Description

Technical Field

[0001] This invention relates to the technical field of supporting facilities for municipal drainage energy dissipation wells, and in particular to a multi-mode energy dissipation drainage energy dissipation well. Background Technology

[0002] Energy dissipation wells are important facilities in municipal drainage pipe networks. Their main function is to dissipate the high-potential-energy water from upstream drainage pipes before discharging it into downstream drainage pipes, thereby reducing the impact of upstream water on downstream drainage pipes. Traditional energy dissipation wells mainly have the following problems:

[0003] (1) Fixed energy dissipation mode is not adaptable to changes in upstream water volume: Traditional drainage energy dissipation wells often adopt fixed energy dissipation modes, such as fixed folded plate energy dissipation, vortex energy dissipation or push flow energy dissipation. However, different energy dissipation modes are applicable to different conditions. For example, folded plate energy dissipation is mainly suitable for small flow water drop, vortex energy dissipation is mainly suitable for medium flow water drop, and push flow energy dissipation is mainly suitable for large flow water drop. In actual operation, the upstream water volume in the drainage network system often changes greatly. The fixed energy dissipation mode adopted by traditional drainage energy dissipation wells cannot adapt to changes in upstream water volume, resulting in poor energy dissipation effect in actual operation.

[0004] (2) The fixed energy dissipation capacity is not adaptable to changes in upstream water volume: Traditional drainage energy dissipation wells are often designed and constructed based on a specific design flow rate, so their energy dissipation capacity is fixed and cannot be automatically adjusted to adapt to changes in upstream water volume. However, the upstream water volume in the actual operation of the drainage network system often varies greatly. Traditional drainage energy dissipation wells cannot adapt to changes in upstream water volume due to their fixed energy dissipation capacity, resulting in poor energy dissipation effect in actual operation. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a multi-mode energy dissipation drainage energy dissipation well to address the shortcomings of the prior art.

[0006] The technical solution of this invention to solve the above-mentioned technical problems is as follows: A multi-mode energy dissipation drainage energy dissipation well includes a well cavity, a well cylinder, a pulling mechanism, a transmission mechanism, an opening and closing mechanism, and an energy dissipation mechanism. The well cylinder is connected to the top of the well cavity. The upper part of the well cavity is sequentially connected with an inlet chamber, a transition chamber, and a flow chamber along the water flow direction. The middle part of the well cavity is sequentially connected with an energy dissipation chamber and a power chamber along the water flow direction. The lower part of the well cavity is sequentially connected with an outlet chamber and a transmission chamber from top to bottom. The transition chamber is located below it. The energy dissipation chamber is connected to the power chamber and the water outlet chamber. The water passage chamber is connected to the transmission chamber via a downpipe. The water inlet chamber is connected to an inlet pipe, and the water outlet chamber is connected to an outlet pipe. The transmission chamber is connected to a main drainage pipe, and the outlet pipe is connected to the main drainage pipe. The pulling mechanism is respectively located in the water inlet chamber, the transition chamber, the water passage chamber, the power chamber, and the energy dissipation chamber. The opening and closing mechanism is located in the power chamber and the energy dissipation chamber. The energy dissipation mechanism is located in... The energy dissipation chamber, the water outlet chamber, and the transmission chamber are comprised of a transmission mechanism housed within the transmission chamber. A pulling mechanism is connected to an opening / closing mechanism, and the pulling mechanism, based on changes in the upstream water flow causing changes in the water level of the inlet chamber, drives the opening / closing mechanism to open or close the corresponding water passages between the energy dissipation chamber and the power chamber. The pulling mechanism, based on changes in the upstream water flow causing changes in the water level of the inlet chamber, drives the opening / closing mechanism to open or close the corresponding connecting channels between the upper, middle, and lower parts of the energy dissipation chamber. The pulling mechanism is connected to the energy dissipation mechanism, and the pulling mechanism, based on changes in the upstream water flow causing changes in the water level of the inlet chamber, drives the energy dissipation mechanism to move, thereby dissipating energy from the water flowing into the energy dissipation chamber. The transmission mechanism is drively connected to the energy dissipation mechanism; water flowing from the water outlet chamber through the downpipe into the transmission chamber can drive the transmission mechanism to rotate, and the rotation of the transmission mechanism can drive the energy dissipation mechanism to rotate, thereby dissipating energy from the water flowing into the energy dissipation chamber.

[0007] The beneficial effects of this invention are as follows: The multi-mode energy dissipation drainage energy dissipation well of this invention, the pulling mechanism drives the opening and closing mechanism to open or close the corresponding water passages between the energy dissipation chamber and the power chamber, as well as the corresponding connecting channels between the upper, middle and lower parts of the energy dissipation chamber, according to the changes in the water level of the inlet chamber caused by the changes in the upstream water volume. Through different corresponding energy dissipation mechanisms, the water flow entering the energy dissipation chamber is dissipated, so that the energy dissipation chamber automatically forms an energy dissipation mode corresponding to the upstream water volume, improving its energy dissipation effect. Simultaneously, the changes in the water level of the inlet chamber caused by the changes in the upstream water volume result in different movement distances of the pulling mechanism and different movement speeds of the transmission mechanism, thus achieving different energy dissipation capabilities. This allows the energy dissipation capacity of the energy dissipation chamber to be automatically adjusted to adapt to changes in the upstream water volume, improving its energy dissipation effect.

[0008] Based on the above technical solution, the present invention can be further improved as follows:

[0009] Further: The inlet chamber and the transition chamber are separated by a first baffle plate, and the transition chamber and the water passage chamber are separated by a second baffle plate. The height of the first baffle plate is lower than that of the second baffle plate. The upper parts of the inlet chamber and the transition chamber are connected, and the upper parts of the transition chamber and the water passage chamber are connected. The inlet chamber and the transition chamber are respectively separated from the energy dissipation chamber by an upper horizontal partition plate. The transition chamber is connected to the energy dissipation chamber through a transition energy dissipation connecting hole provided on the upper horizontal partition plate. The water passage chamber and the power chamber are separated by an upper horizontal partition plate. The water passage chamber is connected to the upper end of the downpipe through a water-power connecting hole provided on the upper horizontal partition plate. The energy dissipation chamber and the power chamber are separated and connected by a vertical partition plate. The energy dissipation chamber and the power chamber are respectively separated from the outlet chamber by a middle horizontal partition plate. The power chamber and the outlet chamber are connected by a power water outlet connecting hole provided on the middle horizontal partition plate. The outlet chamber and the transmission chamber are separated by a lower horizontal partition plate.

[0010] The beneficial effects of the above-mentioned further solution are as follows: by setting the first baffle plate and the second baffle plate with sequentially increasing heights at the upper part of the well cavity, and sequentially forming the water inlet chamber, the transition chamber and the water passage chamber, the transition chamber is connected to the energy dissipation chamber, the water passage chamber is connected to the power chamber, the energy dissipation chamber is connected to the power chamber, and the power chamber is connected to the water outlet chamber, so that the energy dissipation mode and energy dissipation capacity of the energy dissipation chamber can be automatically adjusted to match the different upstream water volume, in conjunction with the pulling mechanism, the energy dissipation mechanism, the transmission mechanism and the opening and closing mechanism.

[0011] Further: The pulling mechanism includes a float, a horizontal tie rod, a vertical main tie rod, a fixed pulley, a pull rope, and a float tie rod. The float and float tie rod are disposed in the water inlet chamber. The horizontal tie rod is disposed in the upper part of the water inlet chamber and the transition chamber. The vertical main tie rod is disposed in the transition chamber and the energy dissipation chamber. The fixed pulley is disposed in the communication area in the upper part of the transition chamber and the water passage chamber and is located directly above the second baffle plate. The lower end of the float tie rod is connected to the float. The upper end of the float tie rod is connected to one end of the horizontal tie rod. The other end of the horizontal tie rod is connected to one end of the pull rope. The other end of the pull rope passes around the fixed pulley and extends into the power chamber and is connected to the opening and closing mechanism. The upper end of the vertical main tie rod is connected to the middle part of the horizontal tie rod. The lower end of the vertical main tie rod extends into the energy dissipation chamber and is connected to the energy dissipation mechanism.

[0012] The beneficial effects of the above-mentioned further solution are as follows: the change in the water level of the inlet chamber caused by the change in the upstream water volume causes the float to move up and down. The up and down movement of the float can drive the float rod to move up and down, which in turn drives the horizontal rod to move up and down, which in turn drives the vertical main rod to move the energy dissipation mechanism, thereby dissipating the energy of the water flow entering the energy dissipation chamber. At the same time, the up and down movement of the horizontal rod drives the opening and closing mechanism to move up and down through the pull rope to open or close the connecting hole between the energy dissipation chamber and the power chamber, as well as the corresponding connecting channels between the upper, middle, and lower parts of the energy dissipation chamber. In this way, the flow diversion method between the energy dissipation chamber and the power chamber and the energy dissipation mode in the energy dissipation chamber can be dynamically adjusted according to the change in the water level of the inlet chamber caused by the change in the upstream water volume. It can also adaptively adjust the distance and speed of the energy dissipation mechanism, thereby realizing the automatic adjustment of the energy dissipation mode and energy dissipation capacity of the energy dissipation chamber according to the change in the upstream water volume, improving the energy dissipation efficiency and the energy dissipation effect.

[0013] Further: The energy dissipation chamber includes an upper energy dissipation chamber, a middle energy dissipation chamber, and a lower energy dissipation chamber arranged from top to bottom. The transition chamber is separated from the upper energy dissipation chamber by the upper horizontal partition, and the transition chamber is connected to the upper energy dissipation chamber through a transition energy dissipation communication hole provided on the upper horizontal partition. The upper energy dissipation chamber and the middle energy dissipation chamber are separated by an upper partition, which has an upper communication hole. An upper communication pipe is provided at the upper communication hole, connecting to the middle energy dissipation chamber. The upper energy dissipation chamber and the middle energy dissipation chamber are connected by an upper communication channel formed by the upper communication hole and the upper communication pipe. The middle energy dissipation chamber and the lower energy dissipation chamber are separated by a middle partition, which has a middle communication hole. A middle communication pipe is provided at the middle communication hole, connecting to the lower energy dissipation chamber. The middle energy dissipation chamber and the lower energy dissipation chamber are connected by a middle communication hole and the middle communication pipe. The upper energy dissipation chamber and the power chamber are connected by a central connecting channel. The vertical partition is provided with an upper water passage, a middle water passage, and a lower water passage. The upper energy dissipation chamber is separated from the power chamber by the vertical partition and connected through the upper water passage. The middle energy dissipation chamber is separated from the power chamber by the vertical partition and connected through the middle water passage. The lower energy dissipation chamber is separated from the power chamber by the vertical partition and connected through the lower water passage. The opening and closing mechanism is located within the upper energy dissipation chamber, the middle energy dissipation chamber, the lower energy dissipation chamber, and the power chamber, and can respectively open or close the upper connecting channel formed by the upper connecting hole and the upper connecting pipe, the middle connecting channel formed by the middle connecting hole and the middle connecting pipe, the upper water passage between the upper energy dissipation chamber and the power chamber, the middle water passage between the middle energy dissipation chamber and the power chamber, and the lower water passage between the lower energy dissipation chamber and the power chamber.

[0014] The beneficial effects of the above-mentioned further solution are as follows: by setting up an upper energy dissipation chamber, a middle energy dissipation chamber, and a lower energy dissipation chamber in the energy dissipation chamber respectively, and forming an upper connecting channel between the upper energy dissipation chamber and the middle energy dissipation chamber through the upper connecting hole and the upper connecting pipe, and forming a middle connecting channel between the middle energy dissipation chamber and the lower energy dissipation chamber 20 through the middle connecting hole and the middle connecting pipe, and setting upper water passage holes, middle water passage holes, and lower water passage holes on the vertical partition respectively, the opening and closing mechanism can open or close the corresponding water passage holes and the connecting channels according to the water level changes in the inlet chamber caused by the different upstream water volume, so that the water flow enters different energy dissipation chambers, thereby realizing the automatic adjustment of the energy dissipation chamber to form a corresponding energy dissipation mode for energy dissipation according to the upstream water volume, and improving the energy dissipation efficiency.

[0015] Further: The energy dissipation mechanism includes an upper energy dissipation mechanism, a middle energy dissipation mechanism, and a lower energy dissipation mechanism. The upper energy dissipation mechanism is located within the upper energy dissipation chamber, the middle energy dissipation mechanism is located within the middle energy dissipation chamber, the lower energy dissipation chamber, the outlet chamber, and the transmission chamber. The pulling mechanism is connected to the upper energy dissipation mechanism, and the transmission mechanism is drively connected to the lower energy dissipation mechanism. The lower energy dissipation mechanism passes through the outlet chamber and extends into the middle energy dissipation chamber, and is drively connected to the middle energy dissipation mechanism. The pulling mechanism can adjust the inlet chamber according to changes in the upstream water flow. The water level change drives the upper energy dissipation mechanism to dissipate energy from the water flow entering the upper energy dissipation chamber, and simultaneously drives the opening and closing mechanism to open or close the upper connecting channel, the upper water inlet, the middle connecting channel, the middle water inlet, and the lower water inlet. The water flow falling from the water inlet chamber into the transmission chamber through the downpipe drives the transmission mechanism to rotate. The rotation of the transmission mechanism drives the lower energy dissipation mechanism and the middle energy dissipation mechanism to rotate. The rotation of the lower energy dissipation mechanism dissipates energy from the water flow entering the lower energy dissipation chamber, and the rotation of the middle energy dissipation mechanism dissipates energy from the water flow entering the middle energy dissipation chamber.

[0016] The beneficial effect of the above-mentioned further solution is that by setting the upper energy dissipation mechanism, the middle energy dissipation mechanism and the lower energy dissipation mechanism in the upper energy dissipation chamber, the middle energy dissipation chamber and the lower energy dissipation chamber respectively, the opening and closing mechanism can be used in conjunction with the opening and closing mechanism to automatically adjust the opening and closing of each energy dissipation chamber according to the different upstream water volume, so that each energy dissipation chamber forms an energy dissipation mode corresponding to the upstream water volume for energy dissipation.

[0017] Further: The upper energy dissipation mechanism includes an upper power rod and multiple sets of upper energy dissipation components arranged vertically and alternately. The upper power rod is vertically installed inside the upper energy dissipation chamber. The pulling mechanism is connected to the upper end of the upper power rod. The lower end of the upper power rod is connected to the upper end of the limiting spring. The lower end of the limiting spring is connected to the upper partition of the energy dissipation chamber. The upper energy dissipation component includes an upper energy dissipation plate and a connecting spring. One end of the upper energy dissipation plate is rotatably installed on the inner wall of the upper energy dissipation chamber. The other end of the upper energy dissipation plate is connected to one end of the connecting spring. The other end of the connecting spring is connected to the upper power rod.

[0018] The lower energy dissipation mechanism includes a lower power rod and multiple sets of lower energy dissipation components arranged parallel from top to bottom. The lower power rod is vertically arranged in the middle energy dissipation chamber, the lower energy dissipation chamber, the outlet chamber, and the transmission chamber. The upper end of the lower power rod extends into the middle energy dissipation chamber and is drivenly connected to the middle energy dissipation mechanism. The lower end of the lower power rod extends into the transmission chamber and is drivenly connected to the transmission mechanism. The lower energy dissipation component includes multiple rotating rods and multiple energy dissipation plate groups. Each rotating rod of the same lower energy dissipation component is arranged around the lower power rod. One end of the rotating rod is rotatably arranged on the inner wall of the lower energy dissipation chamber, and the other end of the rotating rod is drivenly connected to the lower power rod. Each rotating rod is vertically arranged with multiple energy dissipation plate groups from left to right. Each energy dissipation plate group consists of multiple lower energy dissipation plates. Each energy dissipation plate of the same energy dissipation plate group is arranged around the rotating rod. The rotation of the lower power rod can drive the rotating rod and the lower energy dissipation plates to rotate, so as to dissipate energy of the water flow entering the lower energy dissipation chamber.

[0019] The energy dissipation mechanism includes multiple sets of energy dissipation components arranged in parallel from top to bottom. Each energy dissipation component includes multiple horizontally arranged energy dissipation plates. Each energy dissipation plate of the same energy dissipation component is arranged around the lower power rod. The rotation of the lower power rod can drive the energy dissipation plates to rotate, so as to dissipate the energy of the water flow entering the energy dissipation chamber.

[0020] The beneficial effects of the above-mentioned further solution are as follows: the up-and-down movement of the upper power rod drives the connecting spring, thereby pulling the upper energy dissipation plate to rotate and form different tilt angles. This allows for the deflection and energy dissipation of the water flow entering the upper energy dissipation chamber, thus improving the targeting of energy dissipation, increasing the efficiency of energy dissipation, and improving the energy dissipation effect. The varying water levels in the water passage chamber caused by changes in the upstream water volume result in different impact forces from the water outlet pipe on the transmission mechanism. These different impact forces cause the transmission mechanism to rotate at different speeds. The rotation of the rotating shaft drives the lower power rod to rotate at different speeds. These different speeds of the lower power rod, in turn, drive the rotating rod, along with the lower and middle energy dissipation plates, to rotate at different speeds. This allows the lower energy dissipation plate to automatically adjust to different speeds corresponding to different water flow rates, achieving different flow-driven energy dissipation effects. Simultaneously, it also allows the middle energy dissipation plate to automatically adjust to different speeds corresponding to different water flow rates, achieving different vortex energy dissipation effects. This improves the targeting of energy dissipation, increases its efficiency, and enhances its overall effectiveness.

[0021] Furthermore, the lower energy dissipation mechanism also includes an energy dissipation gear pair, which includes a horizontal energy dissipation gear and a vertical energy dissipation gear. One end of the rotating rod is rotatably mounted on the inner wall of the lower energy dissipation chamber, and the other end of the rotating rod is provided with the vertical energy dissipation gear. The horizontal energy dissipation gear is arranged around the lower power rod. The horizontal energy dissipation gear and the vertical energy dissipation gear mesh, and the rotation of the lower power rod can drive the horizontal energy dissipation gear to rotate. The rotation of the horizontal energy dissipation gear can drive the vertical energy dissipation gear to rotate, thereby driving the rotating rod together with the lower energy dissipation plate to rotate.

[0022] The beneficial effect of the above-mentioned further solution is that by setting the horizontal energy dissipation gear and the vertical energy dissipation gear, the horizontal energy dissipation gear and the vertical energy dissipation gear can be driven to rotate under the rotation of the lower power rod. The rotation of the vertical energy dissipation gear will then drive the rotating rod and the lower energy dissipation plate to rotate, thereby realizing the energy dissipation of the water flow entering the lower energy dissipation chamber.

[0023] Further: The opening and closing mechanism includes an upper gate plate, an upper horizontal connecting rod, an L-shaped upper connecting rod, an upper movable plate, a middle gate plate, a middle horizontal connecting rod, an L-shaped middle connecting rod, a middle movable plate, a lower gate plate, a lower horizontal connecting rod, and a main connecting rod. The upper gate plate, middle gate plate, and lower gate plate are respectively disposed in the power chamber. The upper gate plate is correspondingly disposed at the upper water passage and can open or close the upper water passage. The middle gate plate is correspondingly disposed at the middle water passage and can open or close the middle water passage. The lower gate plate is correspondingly disposed at the lower water passage and can open or close the lower water passage. The pulling mechanism is connected to the upper gate plate. One end of the upper horizontal connecting rod is connected to the upper gate plate. One end of the middle horizontal connecting rod is connected to the middle gate plate. One end of the lower horizontal connecting rod is connected to the lower gate plate. The other ends of the upper horizontal connecting rod, the middle horizontal connecting rod, and the lower horizontal connecting rod are respectively connected to the main connecting rod.

[0024] The upper movable plate is movably disposed within the upper connecting pipe. One end of the upper connecting rod is connected to the upper gate plate, and the other end of the upper connecting rod is connected to the upper movable plate. The middle movable plate is movably disposed within the middle connecting pipe. One end of the middle connecting rod is connected to the middle gate plate, and the other end of the middle connecting rod is connected to the middle movable plate.

[0025] The pulling mechanism drives the upper gate plate to move up and down according to the water level change in the inlet chamber caused by the change in the upstream water volume. The up and down movement of the upper gate plate can drive the upper movable plate to move up and down through the upper connecting rod. The up and down movement of the upper gate plate can open or close the upper water passage. The up and down movement of the upper gate plate can also drive the upper movable plate to move up and down through the upper connecting rod to open or close the upper connecting channel. At the same time, the up and down movement of the upper gate plate can drive the main connecting rod to move up and down through the upper horizontal connecting rod. The up and down movement of the main connecting rod can drive the middle gate plate to move up and down through the middle horizontal connecting rod. The up and down movement of the middle gate plate can open or close the middle water passage. The up and down movement of the middle gate plate can also drive the middle movable plate to move up and down through the middle connecting rod to open or close the middle connecting channel. The up and down movement of the upper gate plate can drive the main connecting rod to move up and down through the upper horizontal connecting rod. The up and down movement of the main connecting rod can drive the lower gate plate to move up and down through the lower horizontal connecting rod to open or close the lower water passage.

[0026] The beneficial effects of the above-mentioned further solution are as follows: By setting the upper gate plate and the upper movable plate, the upper gate plate is driven to move up and down under the action of the pulling mechanism, thereby opening or closing the upper water passage. Simultaneously, the up and down movement of the upper gate plate can also drive the upper movable plate to move up and down via the upper connecting rod, thereby opening or closing the upper connecting channel. The up and down movement of the upper gate plate can drive the main connecting rod to move up and down via the upper horizontal connecting rod, and the up and down movement of the main connecting rod drives the middle horizontal connecting rod, along with the middle gate plate, to move up and down. The central water passage can be opened or closed. The vertical movement of the central gate can also drive the vertical movement of the central movable plate through the central connecting rod to open or close the central connecting channel. At the same time, under the action of the main connecting rod, the lower horizontal connecting rod and the lower gate can move up and down together. The vertical movement of the lower gate can open or close the lower water passage, allowing water to enter different energy dissipation chambers. This achieves automatic adjustment of the opening and closing of each energy dissipation chamber according to the different upstream water volume, so that each energy dissipation chamber forms an energy dissipation mode corresponding to the upstream water volume, thereby improving energy dissipation efficiency.

[0027] Further: The transmission mechanism includes a transmission fixed rod, a rotating wheel, multiple rotating plates, and a rotating shaft. One end of the transmission fixed rod is rotatably mounted on the inner wall of the transmission chamber and can rotate around it. The other end of the transmission fixed rod is provided with the rotating wheel. The multiple rotating plates are arranged around the outer periphery of the rotating wheel and located below the lower end of the downpipe. One end of the rotating shaft is connected to the rotating wheel, and the other end of the rotating shaft is provided with the vertical rotating gear. The lower end of the lower power rod is provided with a horizontal rotating gear. The horizontal rotating gear meshes with the vertical rotating gear, and the water flowing from the downpipe into the transmission chamber impacts... The rotating plate rotates, which in turn drives the rotating wheel to rotate. The rotating wheel, in turn, drives the vertical rotating gear via the rotating shaft. The vertical rotating gear, in turn, drives the horizontal rotating gear, which in turn drives the lower power rod to rotate. The lower power rod, in turn, drives the middle energy dissipation plate to rotate, thereby dissipating energy from the water flowing into the middle energy dissipation chamber. The lower power rod, in turn, drives the horizontal energy dissipation gear to rotate, which in turn drives the vertical energy dissipation gear, thereby driving the rotating rod and the lower energy dissipation plate to rotate, thereby dissipating energy from the water flowing into the lower energy dissipation chamber.

[0028] The beneficial effects of the above-mentioned further solution are as follows: by setting the rotating plate, the rotating plate can be driven to rotate the rotating wheel under the action of water flow. The rotation of the rotating wheel drives the rotating shaft and the vertical rotating gear to rotate. The vertical rotating gear drives the horizontal rotating gear and the lower power rod to rotate. The rotation of the lower power rod drives the horizontal energy dissipation gear and the vertical energy dissipation gear to rotate in sequence, thereby driving the rotating rod together with the lower energy dissipation plate to rotate, so as to dissipate the energy of the water flow entering the lower energy dissipation chamber. The rotation of the lower power rod can drive the middle energy dissipation plate to rotate, so as to dissipate the energy of the water flow entering the middle energy dissipation chamber.

[0029] Furthermore, the top of the well shaft is equipped with a well cover that can be opened or closed.

[0030] The beneficial effect of the above-mentioned further solution is that by installing the manhole cover, the drainage energy dissipation well can be easily opened for maintenance. Attached Figure Description

[0039] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0040] like Figures 1 to 6As shown, a multi-mode energy dissipation drainage energy dissipation well includes a well cavity, a well shaft 1, a pulling mechanism, a transmission mechanism, an opening and closing mechanism, and an energy dissipation mechanism. The well shaft 1 is connected to the top of the well cavity. The upper part of the well cavity is sequentially connected with an inlet chamber 5, a transition chamber 6, and a flow chamber 14 along the water flow direction. The middle part of the well cavity is sequentially connected with an energy dissipation chamber 8 and a power chamber 7 along the water flow direction. The lower part of the well cavity is sequentially connected with an outlet chamber 9 and a transmission chamber 10 from top to bottom. The transition chamber 6 is connected to the energy dissipation chamber 8 located below it. The power chamber... The water inlet chamber 7 is connected to the water outlet chamber 9. The water passage chamber 14 is connected to the transmission chamber 10 via the downpipe 17. The water inlet chamber 5 is connected to the water inlet pipe 66. The water outlet chamber 9 is connected to the water outlet pipe 67. The transmission chamber 10 is connected to the main drainage pipe 68. The water outlet pipe 67 is connected to the main drainage pipe 68. The pulling mechanism is respectively installed in the water inlet chamber 5, the transition chamber 6, the water passage chamber 14, the power chamber 7, the energy dissipation chamber 8, the water outlet chamber 9, and the transmission chamber 10. The opening and closing mechanism is installed in the power chamber. Within the energy dissipation chamber 7 and the energy dissipation chamber 8, the energy dissipation mechanism is located within the energy dissipation chamber 8, and the transmission mechanism is located within the transmission chamber 10. The pulling mechanism is connected to the opening and closing mechanism, and the pulling mechanism drives the opening and closing mechanism to open or close the corresponding water passages between the energy dissipation chamber 8 and the power chamber 7 based on the water level changes in the inlet chamber 5 caused by changes in the upstream water flow. The pulling mechanism also drives the opening and closing mechanism to open or close the upper, middle, and lower passages within the energy dissipation chamber 8 based on the water level changes in the inlet chamber 5 caused by changes in the upstream water flow. The corresponding connecting channels between the parts, the pulling mechanism is connected to the energy dissipation mechanism, and the pulling mechanism drives the energy dissipation mechanism to move according to the water level change of the water inlet chamber 5 caused by the change of the upstream water volume, so as to dissipate the energy of the water flow entering the energy dissipation chamber 8. The transmission mechanism is connected to the energy dissipation mechanism. The water flow falling from the water passage chamber 14 through the downpipe 17 into the transmission chamber 10 can drive the transmission mechanism to rotate. The rotation of the transmission mechanism can drive the energy dissipation mechanism to rotate, so as to dissipate the energy of the water flow entering the energy dissipation chamber 8.

[0041] The multi-mode energy dissipation drainage energy dissipation well of the present invention, wherein the pulling mechanism drives the opening and closing mechanism to open or close the corresponding water passages between the energy dissipation chamber 8 and the power chamber 7, as well as the corresponding connecting channels between the upper, middle and lower parts of the energy dissipation chamber 8, according to the changes in the water level of the inlet chamber 5 caused by the change in the upstream water volume. Through different corresponding energy dissipation mechanisms, the water flow entering the energy dissipation chamber 8 is dissipated, so that the energy dissipation chamber 8 automatically forms an energy dissipation mode corresponding to the upstream water volume, improving its energy dissipation effect. Simultaneously, the changes in the water level of the inlet chamber 5 caused by the change in the upstream water volume result in different movement distances of the pulling mechanism and different movement speeds of the transmission mechanism, thus achieving different energy dissipation capabilities. This enables the energy dissipation capacity of the energy dissipation chamber 8 to automatically adjust to the changes in the upstream water volume, improving its energy dissipation effect.

[0042] In one or more embodiments of the present invention, the well cavity is surrounded by a top plate 2, an outer side plate 3, and an outer bottom plate 4, forming an internally hollow cavity structure.

[0043] In one or more embodiments of the present invention, the inlet chamber 5 and the transition chamber 6 are separated by a first baffle plate 69, and the transition chamber 6 and the water passage chamber 14 are separated by a second baffle plate 70. The height of the first baffle plate 69 is lower than that of the second baffle plate 70. The upper parts of the inlet chamber 5 and the transition chamber 6 are connected, and the upper parts of the transition chamber 6 and the water passage chamber 14 are connected. The inlet chamber 5 and the transition chamber 6 are respectively separated from the energy dissipation chamber 8 by an upper horizontal partition plate 11. The transition chamber 6 is connected to the energy dissipation chamber 8 through a transition energy dissipation communication hole 43 provided on the upper horizontal partition plate 11. The water passage chamber 14 and the power chamber 7 are separated by an upper horizontal partition 11, and the water passage chamber 14 is connected to the upper end of the downpipe 17 through a water-power communication hole 44 provided on the upper horizontal partition 11. The energy dissipation chamber 8 and the power chamber 7 are separated and connected by a vertical partition 23. The energy dissipation chamber 8 and the power chamber 7 are respectively separated from the outlet chamber 9 by a middle horizontal partition 12, and the power chamber 7 and the outlet chamber 9 are connected by a power water outlet communication hole 45 provided on the middle horizontal partition 12. The outlet chamber 9 and the transmission chamber 10 are separated by a lower horizontal partition 13.

[0044] Here, the inlet chamber 5 and the transition chamber 6 are separated by the first baffle plate 69 and connected at the top; the transition chamber 6 and the water passage chamber 14 are separated by the second baffle plate 70 and connected at the top; the upper and middle parts of the well cavity are separated by the upper horizontal partition plate 11; the energy dissipation chamber 8 and the power chamber 7 are separated by the vertical partition plate 23 and connected; the middle and lower parts of the well cavity are separated by the middle horizontal partition plate 12; and the outlet chamber 9 and the transmission chamber 10 at the bottom of the well cavity are separated by the lower horizontal partition plate 13, but they are not directly connected. The downpipe 17 passes sequentially through the power chamber 7 and the outlet chamber 9, and finally falls into the transmission chamber 10, directly facing the transmission mechanism. Water from the water passage chamber 14 enters the transmission chamber 10 through the downpipe 17 and impacts the transmission mechanism, causing it to rotate. This rotation of the transmission mechanism then drives the energy dissipation mechanism located in the middle and lower parts of the energy dissipation chamber 8, thereby dissipating energy from the water flowing into the middle and lower parts of the energy dissipation chamber 8. The water flowing into the transmission chamber 10 is directly discharged into the downstream drainage pipe through the main drainage pipe 68. Additionally, the pulling mechanism, based on changes in the water level in the inlet chamber 5 caused by changes in the upstream water volume, drives the energy dissipation mechanism located in the upper part of the energy dissipation chamber 8 to move, thus dissipating energy from the water flowing into the upper part of the energy dissipation chamber 8.

[0045] By setting the first baffle plate 69 and the second baffle plate 70 with sequentially increasing heights at the upper part of the well cavity, the water inlet chamber 5, the transition chamber 6 and the water passage chamber 14 are formed in sequence. The transition chamber 6 is connected to the energy dissipation chamber 8, the water passage chamber 14 is connected to the power chamber 7, the energy dissipation chamber 8 is connected to the power chamber 7, and the power chamber 7 is connected to the water outlet chamber 9. In this way, different energy dissipation modes and energy dissipation processing capabilities can be formed according to the different upstream water volume, in conjunction with the pulling mechanism, the energy dissipation mechanism, the transmission mechanism and the opening and closing mechanism. This enables automatic adjustment of the corresponding energy dissipation mode and energy dissipation processing capability according to the different upstream water volume for energy dissipation.

[0046] In one or more embodiments of the present invention, the pulling mechanism includes a float 37, a horizontal tie rod 38, a vertical main tie rod 39, a fixed pulley 40, a pull rope 41, and a float tie rod 42. The float 37 and the float tie rod 42 are disposed in the water inlet chamber 5. The horizontal tie rod 38 is disposed in the upper part of the water inlet chamber 5 and the transition chamber 6. The vertical main tie rod 39 is disposed in the transition chamber 6 and the energy dissipation chamber 8. The fixed pulley 40 is disposed in the communication area between the transition chamber 6 and the upper part of the water passage chamber 14 and is located in the second stop. Directly above the water plate 70, the lower end of the float rod 42 is connected to the float 37, the upper end of the float rod 42 is connected to one end of the horizontal rod 38, the other end of the horizontal rod 38 is connected to one end of the pull rope 41, the other end of the pull rope 41 passes around the fixed pulley 40 and extends into the power chamber 7 and is connected to the opening and closing mechanism, the upper end of the vertical main rod 39 is connected to the middle of the horizontal rod 38, and the lower end of the vertical main rod 39 extends into the energy dissipation chamber 8 and is connected to the energy dissipation mechanism.

[0047] In practice, the other end of the pull rope 41 is connected to the opening and closing mechanism. Thus, the change in water level in the inlet chamber 5 caused by changes in the upstream water flow can sequentially drive the opening and closing mechanism up and down via the float 37, the float rod 42, the horizontal rod 38, and the pull rope 41. This gradually opens or closes the connecting channels between the upper and middle parts, and between the middle and lower parts of the energy dissipation chamber 8, automatically adjusting the energy dissipation chamber 8 to form an energy dissipation mode corresponding to the upstream water flow. Simultaneously, the change in water level in the inlet chamber 5 caused by changes in the upstream water flow causes the opening and closing mechanism to... The mechanism moves up and down, thereby gradually opening or closing the corresponding water passages between the upper part of the energy dissipation chamber 8 and the power chamber 7, the middle part of the energy dissipation chamber 8 and the power chamber 7, and the lower part of the energy dissipation chamber 8 and the power chamber 7. This allows the water flow to dissipate energy in different parts of the energy dissipation chamber 8, then enter the power chamber 7 through the corresponding water passages between the energy dissipation chamber 8 and the power chamber 7, and then enter the outlet chamber 9 through the connecting channel between the power chamber 7 and the outlet chamber 9. Finally, the water is discharged into the main drainage pipe 68 through the outlet pipe 67 and then into the downstream drainage pipe.

[0048] Thus, the change in the water level of the inlet chamber 5 caused by the change in the upstream water volume causes the float 37 to move up and down. The up and down movement of the float 37 drives the float rod 42 to move up and down, which in turn drives the horizontal rod 38 to move up and down, which in turn drives the vertical main rod 39 to move up and down, thereby driving the energy dissipation mechanism to move, thereby dissipating the energy of the water flowing into the energy dissipation chamber 8. At the same time, the up and down movement of the horizontal rod 38 drives the opening and closing mechanism to move up and down through the pull rope 41 to open or close the energy dissipation chamber 8 and the moving... The connecting holes between the power chambers 7 and the corresponding connecting channels between the upper, middle and lower parts of the energy dissipation chamber 8 allow for dynamic adjustment of the water flow distribution between the energy dissipation chamber 8 and the power chamber 7, as well as the energy dissipation mode within the energy dissipation chamber 8, based on changes in the water level in the inlet chamber 5 caused by changes in the upstream water volume. It also allows for adaptive adjustment of the distance and speed of the energy dissipation mechanism's movement, thereby enabling the energy dissipation mode and energy dissipation capacity of the energy dissipation chamber 8 to be adjusted accordingly based on changes in the upstream water volume, thus improving energy dissipation efficiency and effectiveness.

[0049] In one or more embodiments of the present invention, the energy dissipation chamber 8 includes an upper energy dissipation chamber 18, a middle energy dissipation chamber 19, and a lower energy dissipation chamber 20 arranged from top to bottom. The transition chamber 6 is separated from the upper energy dissipation chamber 18 by the upper horizontal partition 11, and the transition chamber 6 communicates with the upper energy dissipation chamber 18 through the transition energy dissipation communication hole 43 provided on the upper horizontal partition 11. The upper energy dissipation chamber 18 and the middle energy dissipation chamber 19 are separated by an upper partition 21 of the energy dissipation chamber, and an upper communication hole 24 is provided on the upper partition 21 of the energy dissipation chamber. An upper connecting pipe 25 is provided at the location, communicating with the middle energy dissipation chamber 19. The upper energy dissipation chamber 18 and the middle energy dissipation chamber 19 are connected by an upper connecting hole 24 and an upper connecting pipe 25 forming an upper connecting channel. The middle energy dissipation chamber 19 and the lower energy dissipation chamber 20 are separated by a partition plate 22 in the energy dissipation chamber. A middle connecting hole 26 is provided on the partition plate 22 in the energy dissipation chamber. A middle connecting pipe 27 communicating with the lower energy dissipation chamber 20 is provided at the middle connecting hole 26. The middle energy dissipation chamber 19 and the lower energy dissipation chamber 20 are connected by a middle connecting hole 26 in the middle connecting pipe 27. The connecting pipe 27 forms a central connecting channel. The vertical partition 23 is respectively provided with an upper water passage 28, a middle water passage 29, and a lower water passage 30. The upper energy dissipation chamber 18 is separated from the power chamber 7 by the vertical partition 23 and connected through the upper water passage 28. The middle energy dissipation chamber 19 is separated from the power chamber 7 by the vertical partition 23 and connected through the middle water passage 29. The lower energy dissipation chamber 20 is separated from the power chamber 7 by the vertical partition 23 and connected through the lower water passage 30. The opening and closing mechanism is provided... The upper energy dissipation chamber 18, the middle energy dissipation chamber 19, the lower energy dissipation chamber 20, and the power chamber 7 are respectively equipped with an upper connecting channel formed by the upper connecting hole 24 and the upper connecting pipe 25, a middle connecting channel formed by the middle connecting hole 26 and the middle connecting pipe 27, an upper water passage 28 between the upper energy dissipation chamber 18 and the power chamber 7, a middle water passage 29 between the middle energy dissipation chamber 19 and the power chamber 7, and a lower water passage 30 between the lower energy dissipation chamber 20 and the power chamber 7.

[0050] By setting the upper energy dissipation chamber 18, the middle energy dissipation chamber 19, and the lower energy dissipation chamber 20 in the energy dissipation chamber 8 respectively, and forming an upper connecting channel between the upper energy dissipation chamber 18 and the middle energy dissipation chamber 19 through the upper connecting hole 24 and the upper connecting pipe 25, and forming a middle connecting channel between the middle energy dissipation chamber 19 and the lower energy dissipation chamber 20 through the middle connecting hole 26 and the middle connecting pipe 27, and setting the upper water passage hole 28, the middle water passage hole 29, and the lower water passage hole 30 on the vertical partition plate 23 respectively, the opening and closing mechanism can open or close the corresponding water passage hole and the connecting channel according to the water level change of the water inlet chamber 5 caused by the different upstream water volume, so that the water flow enters different energy dissipation chambers, thereby realizing the automatic adjustment of the energy dissipation chamber 8 to form an energy dissipation mode corresponding to the different upstream water volume, thus improving the energy dissipation efficiency.

[0051] In one or more embodiments of the present invention, the energy dissipation mechanism includes an upper energy dissipation mechanism, a middle energy dissipation mechanism, and a lower energy dissipation mechanism. The upper energy dissipation mechanism is disposed within the upper energy dissipation chamber 18, the middle energy dissipation mechanism is disposed within the middle energy dissipation chamber 19, and the lower energy dissipation mechanism is disposed within the middle energy dissipation chamber 19, the lower energy dissipation chamber 20, the outlet chamber 9, and the transmission chamber 10. The pulling mechanism is connected to the upper energy dissipation mechanism, and the transmission mechanism is drivenly connected to the lower energy dissipation mechanism. The lower energy dissipation mechanism passes through the outlet chamber 9 and extends into the middle energy dissipation chamber 19, and is drivenly connected to the middle energy dissipation mechanism. The pulling mechanism can adjust the flow rate according to changes in the upstream water volume. The water level change in water chamber 5 drives the upper energy dissipation mechanism to dissipate energy from the water flow entering the upper energy dissipation chamber 18, and simultaneously drives the opening and closing mechanism to open or close the upper connecting channel, the upper water passage 28, the middle connecting channel, the middle water passage 29, and the lower water passage 30. The water flow falling from the water passage chamber 14 into the transmission chamber 10 via the downpipe 17 drives the transmission mechanism to rotate. The rotation of the transmission mechanism drives the lower energy dissipation mechanism and the middle energy dissipation mechanism to rotate. The rotation of the lower energy dissipation mechanism dissipates energy from the water flow entering the lower energy dissipation chamber 20, and the rotation of the middle energy dissipation mechanism dissipates energy from the water flow entering the middle energy dissipation chamber 19.

[0052] By setting the upper energy dissipation mechanism, the middle energy dissipation mechanism, and the lower energy dissipation mechanism in the upper energy dissipation chamber 18, the middle energy dissipation chamber 19, and the lower energy dissipation chamber 20 respectively, the opening and closing mechanism can be used in conjunction with the opening and closing mechanism to automatically adjust the opening and closing of each energy dissipation chamber according to the different upstream water volume, so that each energy dissipation chamber forms an energy dissipation mode corresponding to the upstream water volume.

[0053] In one or more embodiments of the present invention, the upper energy dissipation mechanism includes an upper power rod 15 and multiple sets of upper energy dissipation components arranged vertically and alternately. The upper power rod 15 is vertically disposed in the upper energy dissipation chamber 18. The pulling mechanism is connected to the upper end of the upper power rod 15. The lower end of the upper power rod 15 is connected to the upper end of the limiting spring 31. The lower end of the limiting spring 31 is connected to the upper partition plate 21 of the energy dissipation chamber. The upper energy dissipation component includes an upper energy dissipation plate 32 and a connecting spring 33. One end of the upper energy dissipation plate 32 is rotatably disposed on the inner wall of the upper energy dissipation chamber 18. The other end of the upper energy dissipation plate 32 is connected to one end of the connecting spring 33. The other end of the connecting spring 33 is connected to the upper power rod 15.

[0054] Here, in order to ensure the stability of the up and down movement of the upper power rod 15, the lower end of the upper power rod 15 is connected to the upper end of the limiting spring 31, and the lower end of the limiting spring 31 is fixed on the upper partition 21 of the energy dissipation chamber.

[0055] The change in the water level of the inlet chamber 5 caused by the change in the upstream water volume causes the pulling mechanism to move up and down. This movement of the pulling mechanism, in turn, drives the upper power rod 15 to move up and down. The upper power rod 15 then pulls the connecting spring 33, which in turn causes one end of the upper energy dissipation plate 32 to rotate around the inner wall of the upper energy dissipation chamber 18. This rotation of the upper energy dissipation plate 32 creates different tilt angles, thereby dissipating energy from the water flowing into the upper energy dissipation chamber 18. The different amounts of water lead to different water levels in the inlet chamber 5. These different water levels cause the pulling mechanism to move, thereby moving the upper power rod 15 and the connecting spring 33 to different positions. This results in different tilt angles of the upper energy dissipation plate 32, and thus different effects on the energy dissipation of the water flow. Therefore, the upper energy dissipation plate 32 can be automatically adjusted to a corresponding tilt angle to dissipate energy according to the different amounts of water coming from upstream, thereby improving the targeting of energy dissipation, increasing the efficiency of energy dissipation, and improving the effect of energy dissipation.

[0056] The lower energy dissipation mechanism includes a lower power rod 16 and multiple sets of lower energy dissipation components arranged parallel from top to bottom. The lower power rod 16 is vertically arranged within the middle energy dissipation chamber 19, the lower energy dissipation chamber 20, the water outlet chamber 9, and the transmission chamber 10. The upper end of the lower power rod 16 extends into the middle energy dissipation chamber 19 and is drivenly connected to the middle energy dissipation mechanism, while the lower end of the lower power rod 16 extends into the transmission chamber 10 and is drivenly connected to the transmission mechanism. The lower energy dissipation components include multiple rotating rods 35 and multiple energy dissipation plate groups. Each rotating rod 35 of the same lower energy dissipation component surrounds... The lower power rod 16 is provided, and one end of the rotating rod 35 is rotatably mounted on the inner wall of the lower energy dissipation chamber 20. The other end of the rotating rod 35 is connected to the lower power rod 16 in a transmission manner. Each rotating rod 35 is vertically arranged with multiple energy dissipation plate groups from left to right. Each energy dissipation plate group is composed of multiple lower energy dissipation plates 36. The lower energy dissipation plates 36 of the same energy dissipation plate group are arranged around the rotating rod 35. The rotation of the lower power rod 16 can drive the rotating rod 35 and the lower energy dissipation plates 36 to rotate, so as to dissipate the energy of the water flow entering the lower energy dissipation chamber 20.

[0057] Here, the different water levels in the water passage chamber 14 result in different impact forces from the water outlet pipe 17 on the transmission mechanism. These different impact forces cause the transmission mechanism to rotate at different speeds. The different speeds of the transmission mechanism drive the lower power rod 16 to rotate at different speeds. The different speeds of the lower power rod 16 drive the rotating rod 35 and the lower energy dissipation plate 36 to rotate at different speeds. This allows the lower energy dissipation plate 36 to automatically adjust to different speeds corresponding to different water flow rates, achieving different flow dissipation effects, thereby improving the targeting of energy dissipation, increasing the efficiency of energy dissipation, and improving the effect of energy dissipation.

[0058] The energy dissipation mechanism includes multiple sets of energy dissipation components arranged in parallel from top to bottom. Each energy dissipation component includes multiple horizontally arranged energy dissipation plates 34. Each energy dissipation plate 34 of the same energy dissipation component is arranged around the lower power rod 16. The rotation of the lower power rod 16 can drive the energy dissipation plate 34 to rotate, so as to dissipate the energy of the water flow entering the energy dissipation chamber 19.

[0059] Here, the different upstream water flow rates result in different water levels in the water passage chamber 14. These different water levels in the water passage chamber 14 cause different impact forces on the transmission mechanism from the downpipe 17. These different impact forces cause the transmission mechanism to rotate at different speeds. The different speeds of the transmission mechanism drive the lower power rod 16 to rotate at different speeds. The different speeds of the lower power rod 16 drive the rotating rod 35 and the middle energy dissipation plate 34 to rotate at different speeds. This allows the middle energy dissipation plate 34 to automatically adjust to different speeds corresponding to different water flow rates, achieving different vortex energy dissipation effects, thereby improving the targeting of energy dissipation, increasing the efficiency of energy dissipation, and improving the energy dissipation effect.

[0060] The up-and-down movement of the upper power rod 15 drives the connecting spring 33 to pull the upper energy dissipation plate 32 to rotate and form different tilt angles. This allows for the deflection and energy dissipation of the water flow entering the upper energy dissipation chamber 18, thereby improving the targeting of energy dissipation, increasing energy dissipation efficiency, and enhancing the energy dissipation effect. The varying water levels in the water passage chamber 14 caused by changes in the upstream water volume result in different impact forces from the water outlet pipe 17 on the transmission mechanism. These different impact forces cause the transmission mechanism to rotate at different speeds, and the different speeds of the transmission mechanism drive the upper energy dissipation plate 32 to rotate at different speeds. The lower power rod 16 rotates at different speeds, which in turn drives the rotating rod 35, along with the lower energy dissipation plate 36 and the middle energy dissipation plate 34, to rotate at different speeds. This allows the lower energy dissipation plate 36 to automatically adjust to different speeds corresponding to different water flow rates, achieving different flow-pushing energy dissipation effects. Simultaneously, it also allows the middle energy dissipation plate 34 to automatically adjust to different speeds corresponding to different water flow rates, achieving different vortex energy dissipation effects. This improves the targeting of energy dissipation, increases its efficiency, and enhances its overall effectiveness.

[0061] In one or more embodiments of the present invention, the lower energy dissipation mechanism further includes an energy dissipation gear pair, which includes a horizontal energy dissipation gear 64 and a vertical energy dissipation gear 65. One end of the rotating rod 35 is rotatably disposed on the inner wall of the lower energy dissipation chamber 20, and the other end of the rotating rod 35 is provided with the vertical energy dissipation gear 65. The horizontal energy dissipation gear 64 is arranged around the lower power rod 16. The horizontal energy dissipation gear 64 and the vertical energy dissipation gear 65 mesh, and the rotation of the lower power rod 16 can drive the horizontal energy dissipation gear 64 to rotate. The rotation of the horizontal energy dissipation gear 64 can drive the vertical energy dissipation gear 65 to rotate, thereby driving the rotating rod 35 together with the lower energy dissipation plate 36 to rotate.

[0062] By setting the horizontal energy dissipation gear 64 and the vertical energy dissipation gear 65, the horizontal energy dissipation gear 64 and the vertical energy dissipation gear 65 can be driven to rotate by the rotation of the lower power rod 16. The rotation of the vertical energy dissipation gear 65 will then drive the rotating rod 35 and the lower energy dissipation plate 36 to rotate, thereby realizing the energy dissipation of the water flow entering the lower energy dissipation chamber 20.

[0063] In one or more embodiments of the present invention, the opening and closing mechanism includes an upper gate plate 46, an upper horizontal connecting rod 53, an L-shaped upper connecting rod 47, an upper movable plate 48, a middle gate plate 49, a middle horizontal connecting rod 54, an L-shaped middle connecting rod 50, a middle movable plate 51, a lower gate plate 52, a lower horizontal connecting rod 55, and a main connecting rod 56. The upper gate plate 46, the middle gate plate 49, and the lower gate plate 52 are respectively disposed in the power chamber 7, and the upper gate plate 46 is correspondingly disposed at the upper water passage 28 and can open or close the upper water passage 28. The middle gate plate 49 is correspondingly disposed at the upper water passage 28. The central water passage 29 can be opened or closed. The lower gate 52 is correspondingly arranged at the lower water passage 30 and can be opened or closed. The pulling mechanism is connected to the upper gate 46. One end of the upper horizontal connecting rod 53 is connected to the upper gate 46. One end of the middle horizontal connecting rod 54 is connected to the middle gate 49. One end of the lower horizontal connecting rod 55 is connected to the lower gate 52. The other ends of the upper horizontal connecting rod 53, the middle horizontal connecting rod 54 and the lower horizontal connecting rod 55 are respectively connected to the main connecting rod 56.

[0064] The upper movable plate 48 is movably disposed within the upper connecting pipe 25. One end of the upper connecting rod 47 is connected to the upper gate plate 46, and the other end of the upper connecting rod 47 is connected to the upper movable plate 48. The middle movable plate 51 is movably disposed within the middle connecting pipe 27. One end of the middle connecting rod 50 is connected to the middle gate plate 49, and the other end of the middle connecting rod 50 is connected to the middle movable plate 51.

[0065] The pulling mechanism drives the upper gate plate 46 to move up and down according to the water level change in the inlet chamber 5 caused by the change in the upstream water volume. The up and down movement of the upper gate plate 46 can open or close the upper water passage 28. The up and down movement of the upper gate plate 46 can also drive the upper movable plate 48 to move up and down through the upper connecting rod 47 to open or close the upper connecting channel. At the same time, the up and down movement of the upper gate plate 46 can drive the main connecting rod 56 to move up and down through the upper horizontal connecting rod 53. The up and down movement of the main connecting rod 56 can be driven by the middle horizontal connecting rod 53. The rod 54 drives the middle gate plate 49 to move up and down. The up and down movement of the middle gate plate 49 can open or close the middle water passage 29. The up and down movement of the middle gate plate 49 can also drive the middle movable plate 51 to move up and down through the middle connecting rod 50 to open or close the middle connecting channel. The up and down movement of the upper gate plate 46 can drive the main connecting rod 56 to move up and down through the upper horizontal connecting rod 53. The up and down movement of the main connecting rod 56 can drive the lower gate plate 52 to move up and down through the lower horizontal connecting rod 55 to open or close the lower water passage 30.

[0066] By configuring the upper gate plate 46 and the upper movable plate 48, the upper gate plate 46 is driven to move up and down under the action of the pulling mechanism, thereby opening or closing the upper water passage 28. Simultaneously, the up-and-down movement of the upper gate plate 46 can also drive the upper movable plate 48 to move up and down via the upper connecting rod 47, opening or closing the upper connecting channel. The up-and-down movement of the upper gate plate 46 can drive the main connecting rod 56 to move up and down via the upper horizontal connecting rod 53, and the up-and-down movement of the main connecting rod 56 drives the middle horizontal connecting rod 54, along with the middle gate plate 49, to move up and down. The up-and-down movement of the middle gate plate 49 can open or close the upper water passage 28. The opening or closing of the central water passage 29 and the vertical movement of the central gate 49 can also drive the vertical movement of the central movable plate 51 via the central connecting rod 50 to open or close the central connecting channel. At the same time, under the action of the main connecting rod 56, the lower horizontal connecting rod 55 and the lower gate 52 move vertically. The vertical movement of the lower gate 52 can open or close the lower water passage 30, allowing water to flow into different energy dissipation chambers. This achieves automatic adjustment of the opening and closing of each energy dissipation chamber according to the different upstream water volume, so that each energy dissipation chamber forms an energy dissipation mode corresponding to the upstream water volume, thereby improving energy dissipation efficiency.

[0067] In practice, the lower gate 52 is preferably a multi-hole flat plate, which facilitates the flow of water entering the lower energy dissipation chamber 20 and being discharged into the power chamber 7 after energy dissipation.

[0068] In one or more embodiments of the present invention, the transmission mechanism includes a transmission fixed rod 57, a rotating wheel 59, multiple rotating plates 60, and a rotating shaft 61. One end of the transmission fixed rod 57 is rotatably mounted on the inner wall of the transmission chamber 10 and can rotate around it. The other end of the transmission fixed rod 57 is provided with the rotating wheel 59. The multiple rotating plates 60 are arranged around the outer periphery of the rotating wheel 59 and located below the lower end of the downpipe 17. One end of the rotating shaft 61 is connected to the rotating wheel 59, and the other end of the rotating shaft 61 is provided with the vertical rotating gear 63. The lower end of the lower power rod 16 is provided with the horizontal rotating gear 62. The horizontal rotating gear 62 meshes with the vertical rotating gear 63, and the water falls from the downpipe 17 into the transmission chamber 10. The water flow within the 0 impacts the rotating plate 60, causing it to rotate. The rotation of the rotating plate 60 drives the rotating wheel 59 to rotate. The rotation of the rotating wheel 59 drives the vertical rotating gear 63 to rotate via the rotating shaft 61. The rotation of the vertical rotating gear 63 drives the horizontal rotating gear 62 to rotate, which in turn drives the lower power rod 16 to rotate. The rotation of the lower power rod 16 drives the middle energy dissipation plate 34 to rotate, thereby dissipating the energy of the water flow entering the middle energy dissipation chamber 19. The rotation of the lower power rod 16 drives the horizontal energy dissipation gear 64 to rotate. The rotation of the horizontal energy dissipation gear 64 drives the vertical energy dissipation gear 65 to rotate, thereby driving the rotating rod 35 together with the lower energy dissipation plate 36 to rotate, thereby dissipating the energy of the water flow entering the lower energy dissipation chamber 20.

[0069] By setting the rotating plate 60, the water flow can drive the rotating plate 60 to rotate, which in turn drives the rotating wheel 59 to rotate. The rotation of the rotating wheel 59 drives the rotating shaft 61 and the vertical rotating gear 63 to rotate. The rotation of the vertical rotating gear 63 drives the horizontal rotating gear 62 and the lower power rod 16 to rotate. The rotation of the lower power rod 16 drives the horizontal energy dissipation gear 64 and the vertical energy dissipation gear 65 to rotate in sequence, which in turn drives the rotating rod 35 together with the lower energy dissipation plate 36 to rotate, so as to dissipate the energy of the water flow entering the lower energy dissipation chamber 20. The rotation of the lower power rod 16 can drive the middle energy dissipation plate 34 to rotate, so as to dissipate the energy of the water flow entering the middle energy dissipation chamber 19.

[0070] In one or more embodiments of the present invention, the top of the well shaft 1 is provided with an openable or closable well cover 58. By providing the well cover 58, the drainage energy dissipation well can be easily opened for maintenance.

[0071] The operation of the multi-mode energy dissipation drainage energy dissipation well of this invention is as follows:

[0072] When no water enters the energy dissipation well from upstream, the energy dissipation well is in its initial state, with the float 37, the horizontal tie rod 38, and the pull rope 41 all in their initial positions. The upper gate plate 46 does not completely cover the upper water passage 28, thus opening the connection between the upper energy dissipation chamber 18 and the power chamber 7. The upper movable plate 48 is inside the upper connecting pipe 25, thereby closing the upper connecting channel formed between the upper energy dissipation chamber 18 and the middle energy dissipation chamber 19 through the upper connecting hole 24 and the upper connecting pipe 25. The middle gate plate 49 does not completely cover the middle water passage 29, and the middle movable plate 51 is inside the middle connecting pipe 27, thereby closing the middle connecting channel formed between the middle energy dissipation chamber 19 and the lower energy dissipation chamber 20 through the middle connecting hole 26 and the middle connecting pipe 27. The lower gate plate 52 does not completely cover the lower water passage 30. The connecting spring 33 is in a horizontal state and is not under force, and the limiting spring 31 is in its initial state and is not under force.

[0073] When upstream water enters the energy dissipation well through the inlet pipe 66, the water first enters the inlet chamber 5. The water level in the inlet chamber 5 rises until it exceeds the first baffle plate 69, after which the water enters the transition chamber 6 and then enters the energy dissipation chamber 8 through the transition energy dissipation connecting hole 43 for energy dissipation. Since the flow rate of the water entering the transition chamber 6 is less than the flow rate of the transition energy dissipation connecting hole 43, all the water entering the transition chamber 6 at this time passes through the transition energy dissipation connecting hole 43 into the energy dissipation chamber 8 for energy dissipation. Simultaneously, the rising water level in the inlet chamber 5 causes the float 37 to move upward, which in turn pushes the horizontal pull rod 38 upward. The upward movement of the horizontal pull rod 38, through the vertical main pull rod 39, pulls the upper power rod 15 upward. The upward movement of the upper power rod 15, in turn, pulls the limiting spring 31 upward. At the same time, the upward movement of the upper power rod 15 pulls one end of the connecting spring 33 to move obliquely upward. The movement of the connecting spring 33, in turn, causes one end of the upper energy dissipation plate 32 to rotate... The vertical partition 23 rotates, causing the upper energy dissipation plate 32 to form an inclined angle with the vertical partition 23. This allows the water flowing into the upper energy dissipation chamber 18 to alternately impact the inclined upper energy dissipation plate 32 as it falls within the upper energy dissipation chamber 18, thus dissipating energy through plate bending. Simultaneously, the upward movement of the horizontal pull rod 38 can also drive the end of the pull rope 41 connected to the upper gate plate 46 to move downward, thereby causing the upper gate plate 46 to move downward. The downward movement of the upper gate plate 46 then connects to the upper horizontal connecting rod 53 and the main connecting rod. 56. The middle horizontal connecting rod 54 and the lower horizontal connecting rod 55 drive the middle gate plate 49 and the lower gate plate 52 to gradually move downward; the upper gate plate 46 moves downward, thereby driving the upper connecting rod 47 to move downward, the upper connecting rod 47 moves downward, thereby driving the upper movable plate 48 to move downward within the upper connecting pipe 25; the middle gate plate 49 moves downward, thereby driving the middle connecting rod 50 to move downward, the middle connecting rod 50 moves downward, thereby driving the middle movable plate 51 to move downward within the middle connecting pipe 27;At this time, due to the small amount of water flowing from upstream, the water level in the inlet chamber 5 rises only slightly. The float 37 moves upward only a small distance, resulting in a small upward movement of the horizontal pull rod 38. Consequently, the end of the pull rope 41 connected to the upper gate 46, the upper gate 46, the middle gate 49, and the lower gate 52 move downward only a small distance. Therefore, the upper gate 46 remains completely uncovered of the upper water passage 28, the middle gate 49 remains completely uncovered of the middle water passage 29, and the lower gate 52 remains completely uncovered of the lower water passage 30. Simultaneously, the upper movable plate 48 does not move outside the upper connecting pipe 25, and the middle movable plate 51 does not move outside the middle connecting pipe 27. The communication channel between the upper energy dissipation chamber 18 and the power chamber 7 is open, the communication channel between the middle energy dissipation chamber 19 and the power chamber 7 is open, the upper communication channel between the upper energy dissipation chamber 18 and the middle energy dissipation chamber 19 is closed, and the middle communication channel between the middle energy dissipation chamber 19 and the lower energy dissipation chamber 20 is closed. At this time, the water flowing into the energy dissipation chamber 8 first enters the upper energy dissipation chamber 18, and during its descent within the upper energy dissipation chamber 18, it alternately impacts the inclined upper energy dissipation plates 32 for energy dissipation. The dissipated water then enters the power chamber 7 through the upper water passage 28, and enters the water outlet chamber 9 through the power outlet water connection hole 45. Subsequently, it is discharged into the downstream drainage pipe through the water outlet pipe 67 and the main drainage pipe 68.

[0074] As the upstream water flow continues to increase, the water first enters the inlet chamber 5, causing the water level in the inlet chamber 5 to continue rising until it exceeds the first baffle plate 69. Then, the water flows into the transition chamber 6 and enters the energy dissipation chamber 8 through the transition energy dissipation connecting hole 43 for energy dissipation. Because the flow rate of the water entering the transition chamber 6 is greater than the flow rate of the transition energy dissipation connecting hole 43, part of the water entering the transition chamber 6 enters the energy dissipation chamber 8 through the transition energy dissipation connecting hole 43 for energy dissipation, while the other part accumulates in the transition chamber 6, causing the water level in the transition chamber 6 to rise until it exceeds the second baffle plate 70. This causes a portion of the water flowing from the transition chamber 6 to enter the water passage chamber 14, and then through the water flow power connection hole 44 and the downpipe 17 into the transmission chamber 10. The water flowing out from the bottom of the downpipe 17 impacts the transmission mechanism, causing it to rotate. At this time, part of the water flowing into the transition chamber 6 enters the energy dissipation chamber 8 for energy dissipation, while the other part passes through the water passage chamber 14 and the downpipe 17 to reach the transmission chamber 10 and drive the transmission mechanism to rotate. Since the water flow rate entering the water passage chamber 14 is less than the drainage capacity of the downpipe 17, all the water flowing into the water passage chamber 14 enters the transmission chamber 10 through the downpipe 17. After flowing out from the bottom of the downpipe 17, the water impacts the rotating plate 60, causing the rotating plate 60 to rotate. The rotation of the rotating plate 60 then sequentially drives the rotating wheel 59, the rotating shaft 61, and the vertical rotating gear 63 to rotate around the transmission fixing rod 57. The rotation of the vertical rotating gear 63 then drives the horizontal rotating gear 62 to rotate, which in turn drives the lower power rod 16 to rotate. The rotation of the lower power rod 16 then drives the middle energy dissipation plate 34 to rotate, thus creating a vortex to dissipate energy in the water flowing into the middle energy dissipation chamber 19. Meanwhile, due to the rising water level in the inlet chamber 5, the float 37 continues to float. The upward movement of the horizontal pull rod 38 pushes the horizontal pull rod 38 upward. The upward movement of the horizontal pull rod 38 pulls the upper power rod 15 upward through the vertical main pull rod 39. The upper power rod 15 continues to move upward, which in turn pulls one end of the connecting spring 33 to continue to move obliquely upward. The movement of the connecting spring 33 causes one end of the upper energy dissipation plate 32 to continue to rotate around the vertical partition 23, thereby making the upper energy dissipation plate 32 and the vertical partition 23 form different larger tilt angles. This allows the water flowing into the upper energy dissipation chamber 18 to alternately hit the tilted upper energy dissipation plate 32 during the process of falling in the upper energy dissipation chamber 18, thus performing corresponding folding plate energy dissipation.Simultaneously, the upward movement of the horizontal pull rod 38 can also drive the end of the pull rope 41 connected to the upper gate plate 46 to move downward, thereby causing the upper gate plate 46 to move downward. The downward movement of the upper gate plate 46, in turn, drives the middle gate plate 49 and the lower gate plate 52 to move downward through the upper horizontal connecting rod 53, the main connecting rod 56, the middle horizontal connecting rod 54, and the lower horizontal connecting rod 55. The downward movement of the upper gate plate 46 then drives the upper connecting rod 47 to move downward, which in turn drives the upper movable plate 48 to move downward within the upper connecting pipe 25. The downward movement of the middle gate plate 49 then drives the middle connecting rod 50 to move downward. The rod 50 moves downward, causing the middle movable plate 51 to move downward within the middle connecting pipe 27. At this time, due to the increased upstream water flow, the water level in the inlet chamber 5 rises and reaches a certain set value, causing the float 37 to move upward a greater distance. This, in turn, causes the horizontal pull rod 38 to move upward a greater distance, increasing the downward movement of the end of the pull rope 41 connected to the upper gate 46, the upper gate 46, the middle gate 49, and the lower gate 52. Consequently, the upper gate 46 gradually and completely covers the upper water passage 28, but the middle gate 49 and the lower gate 52 remain completely uncovered. The lower water inlet 30 is opened, and at the same time, the upper movable plate 48 moves to the outside of the upper connecting pipe 25, while the middle movable plate 51 does not move completely to the outside of the middle connecting pipe 27. Therefore, the communication channel between the upper energy dissipation chamber 18 and the power chamber 7 is closed, the upper communication channel between the upper energy dissipation chamber 18 and the middle energy dissipation chamber 19 is opened, the communication channel between the middle energy dissipation chamber 19 and the power chamber 7 is opened, and the middle communication channel between the middle energy dissipation chamber 19 and the lower energy dissipation chamber 20 is closed. At this time, the water flowing into the energy dissipation chamber 8 first enters the upper energy dissipation chamber 18, and during its descent within the upper energy dissipation chamber 18, it alternately impacts the inclined upper energy dissipation plates 32 to dissipate energy. After energy dissipation... Water flows into the middle energy dissipation chamber 19 through the upper connecting channel formed by the upper connecting hole 24 and the upper connecting pipe 25. As the water falls within the middle energy dissipation chamber 19, it impacts the rotating middle energy dissipation plate 34, thus performing eddy current energy dissipation. The dissipated water then enters the power chamber 7 through the middle water passage 29 and enters the water outlet chamber 9 through the power water outlet connecting hole 45. Subsequently, it is discharged into the downstream drainage pipe through the water outlet pipe 67 and the main drainage pipe 68. Additionally, water flowing into the transmission chamber 10 through the downpipe 17 impacts the rotating plate 60, causing the transmission mechanism to rotate. This portion of the water is then discharged into the downstream drainage pipe through the main drainage pipe 68.

[0075] When the upstream water flow increases, the water first enters the inlet chamber 5, causing the water level in the inlet chamber 5 to continue to rise. After the water level in the inlet chamber 5 exceeds the first baffle plate 69, the water flows into the transition chamber 6. Since the flow rate of the water entering the transition chamber 6 is much greater than the flow capacity through the transition energy dissipation connecting hole 43, part of the water entering the transition chamber 6 enters the energy dissipation chamber 8 through the transition energy dissipation connecting hole 43 for energy dissipation, while the other part passes over the second baffle plate 70 and enters the water passage chamber 14, and then flows through the water flow dynamic connecting hole 44 to the dropper. Pipe 17 enters the transmission chamber 10. The water flowing out from the bottom of the downpipe 17 impacts the transmission mechanism, causing it to rotate. Due to the increase in the upstream water volume, the flow rate of water entering the water passage chamber 14 gradually increases until it exceeds the drainage capacity of the downpipe 17. At this time, part of the water entering the transition chamber 6 enters the energy dissipation chamber 8 for energy dissipation, and another part enters the transmission chamber 10 through the water passage chamber 14 and the downpipe 17, driving the transmission mechanism to rotate; another part accumulates in the water passage chamber 14, increasing its water level; the water in the water passage chamber 14 flows through the... The water flowing into the transmission chamber 10 through the downpipe 17 exits from the bottom of the downpipe 17 and impacts the rotating plate 60. The rotating plate 60 rotates, thereby sequentially driving the rotating wheel 59, the rotating shaft 61, and the vertical rotating gear 63 to rotate around the transmission fixed rod 57. The rotation of the vertical rotating gear 63 drives the horizontal rotating gear 62 to rotate, which in turn drives the lower power rod 16 along with the middle energy dissipation plate 34 to rotate. Due to the increase in the water level in the water passage chamber 14, the water flowing into the transmission chamber 10 after passing through the downpipe 17... The increased impact force of the water flow leads to an increase in the rotational speed of the rotating plate 60, which in turn increases the rotational speed of the middle energy dissipation plate 34 through transmission. This increases the ability of the water flow entering the middle energy dissipation chamber 19 to undergo vortex energy dissipation. In addition, the rotation of the lower power rod 16 can also drive the horizontal energy dissipation gear 64 to rotate. The rotation of the horizontal energy dissipation gear 64 in turn drives the vertical energy dissipation gear 65 to rotate. The rotation of the vertical energy dissipation gear 65 in turn drives the rotating rod 35 and the lower energy dissipation plate 36 to rotate, thereby pushing and dissipating the water flow entering the lower energy dissipation chamber 20.At this time, the rising water level in the inlet chamber 5 causes the float 37 to continue moving upward, which in turn pushes the horizontal pull rod 38 to continue moving upward. The upward movement of the horizontal pull rod 38, through the vertical main pull rod 39, pulls the upper power rod 15 to continue moving upward. The upward movement of the upper power rod 15, in turn, pulls one end of the connecting spring 33 to continue moving obliquely upward. The movement of the connecting spring 33, in turn, causes one end of the upper energy dissipation plate 32 to continue rotating around the vertical partition 23, thereby causing the upper energy dissipation plate 32 and the vertical partition 23 to form a larger tilt angle, thus allowing the water entering the chamber to flow more smoothly. As the water flow in the upper energy dissipation chamber 18 falls within it, it alternately impacts the inclined upper energy dissipation plate 32, resulting in corresponding plate-based energy dissipation. Simultaneously, the upward movement of the horizontal pull rod 38 causes the end of the pull rope 41 connected to the upper gate plate 46 to move downwards, thereby causing the upper gate plate 46 to move downwards. The downward movement of the upper gate plate 46, in turn, via the upper horizontal connecting rod 53, main connecting rod 56, middle horizontal connecting rod 54, and lower horizontal connecting rod 55, drives the middle gate plate 49 and lower gate plate 52 to move downwards. The downward movement of the upper gate plate 46 further drives the upper connecting rod 47 to move downwards. This causes the upper movable plate 48 to move downward within the upper connecting pipe 25, and the middle gate plate 49 to move downward, which in turn causes the middle connecting rod 50 to move downward, thereby causing the middle movable plate 51 to move downward within the middle connecting pipe 27. At this time, due to the increased upstream water volume, the water level in the inlet chamber 5 rises and reaches another larger set value, thereby increasing the upward movement distance of the float 37, which in turn increases the upward movement distance of the horizontal pull rod 38, and increases the downward movement distance of the pull rope 41, the upper gate plate 46, the middle gate plate 49, and the lower gate plate 52, thereby causing... The upper gate plate 46 completely covers the upper water passage 28, the middle gate plate 49 completely covers the middle water passage 29, and the lower gate plate 52 completely covers the lower water passage 30. At the same time, the upper movable plate 48 moves to the outside of the upper connecting pipe 25, and the middle movable plate 51 moves to the outside of the middle connecting pipe 27. Therefore, the connection between the upper energy dissipation chamber 18 and the power chamber 7 is closed, the connection between the middle energy dissipation chamber 19 and the power chamber 7 is closed, the upper connecting channel between the upper energy dissipation chamber 18 and the middle energy dissipation chamber 19 is opened, and the middle connecting channel between the middle energy dissipation chamber 19 and the lower energy dissipation chamber 20 is opened.At this time, the water flowing into the energy dissipation chamber 8 first enters the upper energy dissipation chamber 18, and during its descent within the upper energy dissipation chamber 18, it alternately impacts the inclined upper energy dissipation plates 32 for plate-based energy dissipation. The dissipated water then enters the middle energy dissipation chamber 19 through the upper connecting channel formed by the upper connecting hole 24 and the upper connecting pipe 25, and during its descent within the middle energy dissipation chamber 19, it impacts the rotating middle energy dissipation plate 34, thereby performing vortex energy dissipation. The dissipated water then enters the lower energy dissipation chamber 20 through the middle connecting channel formed by the middle connecting hole 26 and the middle connecting pipe 27. After the lower gate plate 52 completely covers the lower water passage 30, the water entering the lower energy dissipation chamber 20 is completely discharged into the power chamber 7 through the orifice on the lower gate plate 52. However, since the drainage volume of the orifice on the lower gate plate 52 is related to the water level in the lower energy dissipation chamber 20, the initial water volume entering the lower energy dissipation chamber 20 is greater than that on the lower gate plate 52. The water level in the lower energy dissipation chamber 20 gradually increases until it reaches the set level. At this point, the amount of water entering the lower energy dissipation chamber 20 is equal to the amount of water discharged from the orifice on the lower gate 52. The water level in the lower energy dissipation chamber 20 then remains stable and no longer increases. Throughout the process of the water level increasing and remaining stable in the lower energy dissipation chamber 20, the lower energy dissipation plate 36 rotates to push and dissipate the water flow entering the lower energy dissipation chamber 20. The dissipated water flows through the lower water passage 30 into the power chamber 7 and through the power water outlet connection hole 45 into the water outlet chamber 9. Subsequently, it flows through the water outlet pipe 67 and the main drainage pipe 68 into the downstream drainage pipe. Additionally, the water flowing into the transmission chamber 10 through the downpipe 17 impacts the rotating plate 60, causing the transmission mechanism to rotate. This portion of the water then flows through the main drainage pipe 68 into the downstream drainage pipe.

[0076] When there is no more water coming from upstream, the water stored in the inlet chamber 5 will be discharged in reverse through the inlet pipe 66 into the upstream drainage pipe, causing the water level in the inlet chamber 5 to drop. This will cause the float 37 to return to its initial state, as it will no longer be subject to buoyancy. The water accumulated in the upper energy dissipation chamber 18, the middle energy dissipation chamber 19, and the lower energy dissipation chamber 20 will enter the outlet chamber 9 through the corresponding orifices, and then be discharged into the downstream drainage pipe through the outlet pipe 67 and the main drainage pipe 68. Since the float 37 is no longer subject to buoyancy, the horizontal pull rod 38 and the pull rope 41 will return to their initial positions. The corresponding gate, movable plate, and spring will all return to their initial states, meaning that the upper gate 46 will not completely cover the upper water passage 28. This opens the communication channel between the upper energy dissipation chamber 18 and the power chamber 7; the upper movable plate 48 is inside the upper connecting pipe 25, thereby closing the upper communication channel formed between the upper energy dissipation chamber 18 and the middle energy dissipation chamber 19 through the upper connecting hole 24 and the upper connecting pipe 25; the middle gate plate 49 does not completely cover the middle water passage hole 29, and the middle movable plate 51 is inside the middle connecting pipe 27, thereby closing the middle communication channel formed between the middle energy dissipation chamber 19 and the lower energy dissipation chamber 20 through the middle connecting hole 26 and the middle connecting pipe 27; the lower gate plate 52 does not completely cover the lower water passage hole 30; the connecting spring 33 is in a horizontal state and is not under force, and the limiting spring 31 is in an initial state and is not under force.

[0077] During inspection and maintenance, the well cover 58 on the top of the well shaft 1 can be opened, and maintenance personnel or equipment can enter the well through the well shaft 1 to carry out inspection and maintenance work.

[0078] Compared to traditional drainage and energy dissipation wells, the features of this invention are:

[0079] (1) In response to changes in the upstream water volume, the energy dissipation well automatically adjusts to form an energy dissipation mode that is adapted to the upstream water volume for energy dissipation: by setting up a pulling mechanism, a transmission mechanism, an opening and closing mechanism, an upper energy dissipation mechanism, a middle energy dissipation mechanism, and a lower energy dissipation mechanism, the pulling mechanism and the transmission mechanism move according to the different water levels in the inlet chamber caused by the different upstream water volume, thereby driving the opening and closing mechanism, the upper energy dissipation mechanism, the middle energy dissipation mechanism, and the lower energy dissipation mechanism to move respectively, forming different energy dissipation modes such as folded plate energy dissipation, folded plate energy dissipation + vortex energy dissipation, and folded plate energy dissipation + vortex energy dissipation + push flow energy dissipation, which are corresponding to the upstream water volume. This improves the targeting of energy dissipation, enhances the efficiency of energy dissipation, and improves the effect of energy dissipation. Therefore, the energy dissipation mode of the drainage energy dissipation well of this invention is highly adaptable to changes in the upstream water volume.

[0080] (2) In response to changes in the upstream water volume, the energy dissipation well automatically adjusts its energy dissipation capacity to adapt to the upstream water volume: By setting up multiple energy dissipation units, and by setting up an inlet chamber, a transition chamber, a flow chamber, a pulling mechanism, a transmission mechanism, an opening and closing mechanism, an upper energy dissipation chamber, a middle energy dissipation chamber, and a lower energy dissipation chamber, as well as supporting upper, middle, and lower energy dissipation mechanisms, the water levels in the inlet chamber, transition chamber, and flow chamber are different due to the different upstream water volume, which in turn causes different distances for the pulling mechanism and different speeds for the transmission mechanism, thus causing different distances for the upper energy dissipation mechanism and different speeds for the middle and lower energy dissipation mechanisms, thereby achieving different energy dissipation capacities. This realizes the automatic adjustment of the energy dissipation capacity of the upper, middle, and lower energy dissipation chambers to match the water flow rate entering each energy dissipation chamber, thereby ensuring its energy dissipation effect. Therefore, the energy dissipation capacity of the drainage energy dissipation well of this invention is highly adaptable to changes in the upstream water volume.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
