Description

A multi-stage energy dissipation drainage energy dissipation well Technical Field

[0001] This invention relates to the technical field of supporting facilities for drainage energy dissipation wells, and particularly to multi-stage energy dissipation drainage energy dissipation wells. Background Technology

[0002] Energy dissipation wells are crucial components of municipal drainage networks. Their primary function is to dissipate the energy of water flowing from upstream drainage pipes at higher elevations before discharging it into downstream pipes at lower elevations, thereby reducing the impact of upstream water flow on the downstream drainage network. Traditional energy dissipation wells suffer from the following main problems:

[0003] (1) The first-level energy dissipation mode is adopted, resulting in poor energy dissipation effect: the transmission drainage energy dissipation well often adopts the first-level energy dissipation mode. This energy dissipation method often results in some water flow energy being discharged into the downstream drainage pipe before it is eliminated, thus the energy dissipation effect is poor. Moreover, the energy reduction gradient of the first-level energy dissipation mode is large, which also has a large impact on the well body of the drainage energy dissipation well. Long-term continuous operation will cause serious damage to the well body of the drainage energy dissipation well.

[0004] (2) Poor adaptability to changes in the inflow of water from upstream drainage pipes: Traditional drainage energy dissipation wells are designed based on a certain design flow rate. When the inflow of water from upstream drainage pipes changes significantly from the design flow rate, the energy dissipation effect is often poor.

[0005] (3) The energy of the water coming from the upstream drainage pipe is not fully utilized: The water coming from the upstream drainage pipe has a high potential energy. The traditional drainage energy dissipation well directly consumes the energy without making full use of it, resulting in energy waste.

[0006] (4) The vertical space is not fully utilized: The structure of the transmission drainage energy dissipation well is relatively simple, and the vertical space is not fully utilized, resulting in a large planar size of the well, thus occupying a large area and requiring a high investment. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a multi-stage energy dissipation drainage energy dissipation well, which addresses the shortcomings of the prior art.

[0008] The technical solution of this invention to solve the above-mentioned technical problems is as follows: A multi-stage energy dissipation drainage energy dissipation well includes a well cavity, a baffle mechanism, a slide rod transmission mechanism, a cover plate driving mechanism, a cover plate, a gear driving mechanism, a vertical stirring mechanism, and a horizontal stirring mechanism. The well cavity is divided into a baffle energy dissipation chamber, a water cushion energy dissipation chamber, a transition chamber, a stirring energy dissipation chamber, a power chamber, and a water outlet chamber by a partition. The baffle energy dissipation chamber is located in the upper part of the well cavity. The power chamber, the water cushion energy dissipation chamber, the transition chamber, and the water outlet chamber are arranged sequentially adjacent to each other in the baffle energy dissipation chamber. Below, the baffle energy dissipation chamber is connected to the water cushion energy dissipation chamber and the water outlet chamber respectively. The transition chamber is horizontally adjacent to and connected to the water cushion energy dissipation chamber and the water outlet chamber respectively. The transition chamber is vertically adjacent to and connected to the stirring energy dissipation chamber. The power chamber is adjacent to the baffle energy dissipation chamber, the water cushion energy dissipation chamber and the stirring energy dissipation chamber respectively. The upper part of the side wall of the baffle energy dissipation chamber away from the water outlet chamber is connected to the water inlet pipe. The bottom of the side wall of the water outlet chamber away from the transition chamber is connected to the water outlet pipe.

[0009] The baffle energy dissipation chamber is equipped with the baffle mechanism, the power chamber is equipped with the gear drive mechanism, the slide rod transmission mechanism is located in the baffle energy dissipation chamber and the power chamber, and the upper end of the slide rod transmission mechanism is connected to the baffle mechanism, the lower end of the slide rod transmission mechanism is connected to the gear drive mechanism, the vertical stirring mechanism is located in the water cushion energy dissipation chamber and the power chamber, the horizontal stirring mechanism is located in the stirring energy dissipation chamber and the power chamber, and the gear drive mechanism is respectively drivenly connected to the vertical stirring mechanism and the horizontal stirring mechanism and can drive the vertical stirring mechanism and the horizontal stirring mechanism to rotate, the top of the cover plate drive mechanism is fixedly located on the inner top wall of the baffle energy dissipation chamber, and the bottom of the cover plate drive mechanism is respectively connected to the corresponding cover plates that are slidably located at the connecting channel between the baffle energy dissipation chamber and the water cushion energy dissipation chamber, the connecting channel between the water cushion energy dissipation chamber and the transition chamber, and the connecting channel between the transition chamber and the stirring energy dissipation chamber, and can drive each cover plate to slide up and down to open or close the corresponding connecting channel.

[0010] The beneficial effects of this invention are as follows: The multi-stage energy dissipation drainage energy dissipation well of this invention, by setting a baffle mechanism in the baffle energy dissipation chamber, can block and dissipate energy when the water flow entering the baffle energy dissipation chamber falls. At the same time, during the energy dissipation process, the baffle mechanism can drive the slide rod transmission mechanism to move downward, thereby driving the gear drive mechanism to rotate, which in turn drives the vertical stirring mechanism and the horizontal stirring mechanism to rotate. In this way, the water flow in the water cushion energy dissipation chamber and the stirring energy dissipation chamber can be stirred and dissipated. At the same time, the cover plate drive mechanism can also automatically switch to the energy dissipation mode of first-stage, second-stage, or third-stage energy dissipation according to the changes in the water level in the baffle energy dissipation chamber caused by the changes in the upstream water volume. This effectively improves the adaptability of the drainage energy dissipation well to changes in the water volume, realizes differentiated energy dissipation according to different water volumes, and simultaneously realizes multi-stage energy dissipation of the water flow, thereby improving the energy dissipation efficiency.

[0011] Based on the above technical solution, the present invention can be further improved as follows:

[0012] Further: A horizontal upper partition plate connected to the bottom of the inlet pipe is provided on the upper part of the baffle energy dissipation chamber near the inlet pipe. The baffle energy dissipation chamber is separated from the power chamber, water cushion energy dissipation chamber, transition chamber, and outlet chamber by the horizontal middle partition plate provided at the bottom of the baffle energy dissipation chamber. The water cushion energy dissipation chamber is separated from the power chamber, and the transition chamber is separated from the stirring energy dissipation chamber by the horizontal lower partition plate provided at the bottom of the well cavity. The upper end of the baffle mechanism is connected to the bottom of the horizontal upper partition plate, and the lower end of the baffle mechanism is connected to the top of the horizontal middle partition plate. The horizontal middle partition plate is provided with a primary orifice connecting the baffle energy dissipation chamber and the water cushion energy dissipation chamber, and a baffle energy dissipation chamber outlet hole connecting the baffle energy dissipation chamber and the outlet chamber. A primary well shaft is connected below the primary orifice. The baffle energy dissipation chamber and the water cushion energy dissipation chamber are connected by the primary orifice. The first connecting channel formed by the first-stage well shaft is connected to the first-stage well shaft. A first-stage cover plate is slidably installed inside the first-stage well shaft. The bottom of the cover plate driving mechanism is connected to the top of the first-stage cover plate. The movement of the cover plate driving mechanism can drive the first-stage cover plate to slide up and down inside the first-stage well shaft, thereby opening or closing the first connecting channel between the baffle energy dissipation chamber and the water cushion energy dissipation chamber. A second-stage orifice is provided on the horizontal lower partition plate, connecting the transition chamber and the stirring energy dissipation chamber. A second-stage well shaft is connected below the second-stage orifice. The transition chamber and the stirring energy dissipation chamber are connected through a second connecting channel formed by the second-stage orifice and the second-stage well shaft. A second-stage cover plate is slidably installed inside the second-stage well shaft. The bottom of the cover plate driving mechanism is connected to the top of the second-stage cover plate. The movement of the cover plate driving mechanism can drive the second-stage cover plate to slide up and down inside the second-stage well shaft, thereby opening or closing the second connecting channel.

[0013] The power chamber has an L-shaped cross-section. It is horizontally separated from the water cushion energy dissipation chamber by a first vertical partition and from the stirring energy dissipation chamber by a fourth vertical partition. The side of the water cushion energy dissipation chamber furthest from the power chamber is horizontally separated from the transition chamber by a second vertical partition. The second vertical partition has an upper opening in its middle section connecting the water cushion energy dissipation chamber and the transition chamber, and a lower opening at its bottom connecting the two chambers. The water cushion energy dissipation chamber and the transition chamber are connected by an upper connecting channel formed by the upper and lower openings, and a bottom connecting channel formed by the lower and upper openings, respectively. The second vertical partition slides on the water cushion energy dissipation chamber. A middle cover plate is provided, and the bottom of the cover plate driving mechanism is connected to the top of the middle cover plate. The movement of the cover plate driving mechanism can drive the middle cover plate to slide up and down on the vertical second partition plate to open or close the bottom connecting channel. The transition chamber is horizontally separated from the water outlet chamber on the side away from the water pad energy dissipation chamber by a vertical third partition plate. The bottom of the vertical third partition plate is provided with a transition chamber water outlet hole connecting the transition chamber and the water outlet chamber. The stirring energy dissipation chamber is horizontally separated from the water outlet chamber on the side away from the power chamber by a vertical fifth partition plate. The bottom of the vertical fifth partition plate is provided with a stirring energy dissipation chamber water outlet hole connecting the stirring energy dissipation chamber and the water outlet chamber.

[0014] The power chamber is divided into a drive chamber and a gear transmission chamber. The drive chamber is located below the baffle energy dissipation chamber and is separated from the baffle energy dissipation chamber by the horizontal middle partition. The gear transmission chamber is located below the water cushion energy dissipation chamber and is separated from the water cushion energy dissipation chamber by the horizontal lower partition. The drive chamber is located on the same side of the water cushion energy dissipation chamber and the gear transmission chamber (the side away from the transition chamber). The upper part of the drive chamber is horizontally separated from the water cushion energy dissipation chamber by the vertical first partition, and the lower part of the drive chamber is completely connected to the gear transmission chamber. The side of the gear transmission chamber away from the drive chamber is horizontally separated from the stirring energy dissipation chamber by the vertical fourth partition.

[0015] The beneficial effects of the above-mentioned further solution are: by dividing the interior of the well cavity into different chambers through the horizontal upper partition, horizontal middle partition, horizontal lower partition, vertical first partition, vertical second partition, vertical third partition, vertical fourth partition and vertical fifth partition, on the one hand, it can facilitate the synchronous and coordinated operation of multiple drive mechanisms, and on the other hand, it can achieve multi-stage energy dissipation by opening or closing different water flow channels, thereby improving energy dissipation efficiency.

[0016] Furthermore, a water distribution plate is provided on the top of the horizontal upper partition away from the water inlet pipe, and water distribution holes are evenly distributed on the water distribution plate.

[0017] The beneficial effect of the above-mentioned further solution is that by setting the water distribution plate and water distribution hole, the upstream water entering the baffle energy dissipation chamber can be evenly distributed to stabilize the outflow of water.

[0018] Further: The cover plate driving mechanism includes a float, a pull rope, two fixed pulleys, a rod assembly, and a spring. The two fixed pulleys are spaced apart on the inner top wall of the baffle energy dissipation chamber. The float is disposed in the baffle energy dissipation chamber and located between the water inlet pipe and the water distribution plate. One end of the pull rope is connected to the top of the float, and the other end of the pull rope passes around the two fixed pulleys and is connected to the top of the rod assembly. The bottom of the rod assembly is connected to the top of the first-stage cover plate, the upper end of the spring, and the top of the second-stage cover plate, respectively. The lower end of the spring... Connected to the top of the middle cover plate, the change in the amount of upstream water discharged through the inlet pipe can cause the water level in the baffle energy dissipation chamber to change, thereby driving the float to move up and down, which in turn drives the pull rope to move, and in turn drives the rod assembly to move up and down. The up and down movement of the rod assembly respectively drives the first-stage cover plate to slide up and down in the first-stage well shaft, the middle cover plate to slide up and down on the vertical second partition plate, and the second-stage cover plate to slide up and down in the second-stage well shaft, so as to open or close the first connecting channel, the bottom connecting channel, and the second connecting channel respectively.

[0019] The beneficial effects of the above-mentioned further solution are as follows: By setting the float, when the upstream water volume changes, the float moves up and down, thereby pulling the pull rope up and down and driving the rod assembly to move up and down, which in turn drives the first-stage cover plate to slide up and down in the first-stage well shaft, the middle cover plate to slide up and down on the vertical second partition plate, and the second-stage cover plate to slide up and down in the second-stage well shaft. The first-stage cover plate slides up and down in the first-stage well shaft to open or close the first connecting channel; the middle cover plate slides up and down to open or close the lower orifice, thereby opening or closing the bottom connecting channel; the second-stage cover plate slides up and down in the second-stage well shaft to open or close the second connecting channel, thereby realizing automatic switching of energy dissipation mode and improving the adaptability of the drainage energy dissipation well to changes in upstream water volume.

[0020] Further: The rod assembly includes one horizontal rod and three vertical rods. The top of the horizontal rod is connected to one end of the pull rope, and the bottom of the horizontal rod is connected to the upper ends of the three vertical rods respectively. The lower ends of the three vertical rods are connected to the top of the first-stage cover plate, the upper end of the spring, and the top of the second-stage cover plate respectively.

[0021] The beneficial effect of the above-mentioned further solution is that, through the horizontal bar and the three vertical bars, the pull rope can drive the three vertical bars to move up and down through the horizontal bar, thereby driving the first-level cover plate, the middle cover plate and the second-level cover plate to slide up and down, thereby realizing the opening or closing of different connecting channels and completing the switching of different energy dissipation modes.

[0022] Further: The baffle mechanism is composed of multiple vertically arranged baffle springs and multiple horizontally arranged baffles connected alternately from top to bottom. The upper end of the first baffle spring from top to bottom is connected to the bottom of the horizontal upper partition, and the lower end of the first baffle spring from top to bottom is connected to the top of the first baffle from top to bottom. The upper ends of each of the middle baffle springs are connected to the bottom of the baffle corresponding to them above, and the lower ends of each of the middle baffle springs are connected to the top of the baffle corresponding to them below. The upper end of the last baffle spring is connected to the bottom of the last baffle from top to bottom above it, and the lower end of the last baffle spring is connected to the top of the horizontal middle partition. The upper end of the slide rod transmission mechanism is connected to the bottom of the first baffle from top to bottom.

[0023] The beneficial effects of the above-mentioned further solution are as follows: by alternately connecting multiple baffle springs and multiple horizontally arranged baffles, the upstream water flowing into the baffle energy dissipation chamber from the water inlet pipe falls downwards and impacts each of the baffles to dissipate energy. At the same time, each of the baffles moves downwards under the impact of the water flow, thereby compressing or stretching the corresponding baffle springs downwards, which in turn pulls the first baffle downwards, causing the slide rod transmission mechanism to move downwards, which in turn drives the gear drive mechanism to rotate, thereby driving the vertical stirring mechanism and the horizontal stirring mechanism to rotate.

[0024] Further: The slide bar transmission mechanism includes a vertical guide rod, a fixed plate, a movable rod, an L-shaped rotating connecting rod, and a rotating ring. The upper end of the vertical guide rod is connected to the bottom of the first baffle plate from top to bottom. At least two rod sleeves are provided on the inner wall of the power chamber near the water inlet pipe. The middle part of the vertical guide rod is sleeved in the rod sleeve. The fixed plate is fixedly provided on the lower part of the vertical guide rod. One end of the movable rod is movably connected to the fixed plate, and the other end of the movable rod is connected to one end of the rotating connecting rod. The other end of the rotating connecting rod is connected to the outer wall of the rotating ring. The rotating ring is driven by the gear drive mechanism. When the upstream water flowing into the energy dissipation chamber from the inlet pipe falls downwards and impacts each of the baffles to dissipate energy, each baffle moves downwards under the impact of the water flow, thereby compressing or stretching the corresponding baffle springs downwards. This, in turn, pulls the first baffle downwards, driving the vertical guide rod to slide downwards. When the vertical guide rod slides downwards, it drives the movable rod to rotate through the fixed plate. The rotation of the movable rod drives the rotating connecting rod to rotate, which in turn drives the rotating ring to rotate. The rotation of the rotating ring drives the gear drive mechanism to rotate, which in turn drives the vertical stirring mechanism and the horizontal stirring mechanism to rotate respectively.

[0025] The beneficial effect of the above-mentioned further solution is that, under the impact of the water flow, the vertical guide rod is driven to slide downward by the first baffle from top to bottom. In this way, the movable rod, rotating connecting rod and connecting ring can be driven to move sequentially through the fixed plate, thereby driving the gear drive mechanism to rotate, and then driving the vertical stirring mechanism and the horizontal stirring mechanism to rotate, thereby stirring and dissipating the water flow in the water cushion energy dissipation chamber and the stirring energy dissipation chamber.

[0026] Further: The gear drive mechanism includes a drive gear, an upper gear, a middle gear, and a gear shaft. The upper gear is located above the drive gear, and the middle gear is located in the middle of the drive gear near the stirring and energy dissipation chamber. The drive gear meshes with the upper gear and the middle gear respectively. One end of the gear shaft is connected to the center of the drive gear, and the other end of the gear shaft is connected to the rotating ring. When the rotating ring rotates, it can drive the gear shaft to rotate, thereby driving the drive gear to rotate, which in turn drives the upper gear and the middle gear to rotate, and in turn drives the vertical stirring mechanism and the horizontal stirring mechanism to rotate.

[0027] The beneficial effect of the above-mentioned further solution is that by setting the drive gear to mesh with the upper gear and the middle gear respectively, when the drive gear rotates, the drive gear can drive the upper gear and the middle gear to rotate respectively, so as to drive the vertical stirring mechanism and the horizontal stirring mechanism to rotate respectively, thereby realizing the stirring and energy dissipation of the water flow in the water cushion energy dissipation chamber and the stirring energy dissipation chamber.

[0028] Further: The vertical stirring mechanism includes a vertical rotating shaft and multiple vertical shaft stirring blades. The vertical rotating shaft is vertically arranged in the water cushion energy dissipation chamber and the gear transmission chamber, and the lower end of the vertical rotating shaft is connected to the top center of the upper gear. Each of the vertical shaft stirring blades is located in the water cushion energy dissipation chamber and is arranged vertically at intervals on the upper part of the vertical rotating shaft.

[0029] The horizontal stirring mechanism includes a horizontal rotating shaft and multiple horizontal shaft stirring blades. The horizontal rotating shaft is horizontally arranged in the stirring energy dissipation chamber and the gear transmission chamber, and the end of the horizontal rotating shaft near the middle gear is connected to the center of the side of the middle gear. Each of the horizontal shaft stirring blades is located in the stirring energy dissipation chamber and is horizontally spaced on the horizontal rotating shaft.

[0030] The drive gear can simultaneously drive the vertical shaft and the horizontal shaft to rotate via the upper gear and the middle gear, respectively, so as to drive the vertical shaft stirring plate and the horizontal shaft stirring plate to rotate, thereby stirring and dissipating the water flow entering the water pad energy dissipation chamber and the stirring energy dissipation chamber, respectively.

[0031] The beneficial effects of the above-mentioned further solutions are as follows: the rotation of the upper gear drives the vertical shaft to rotate, thereby driving the vertical shaft stirring plate to rotate and thus stirring the water flow in the water cushion energy dissipation chamber to enhance the energy dissipation effect; the rotation of the middle gear drives the horizontal shaft to rotate, thereby driving the horizontal shaft stirring plate to rotate and thus stirring and dissipating the water flow entering the stirring energy dissipation chamber from the transition chamber, effectively realizing staged energy dissipation and improving energy dissipation efficiency.

[0032] Furthermore, a well cylinder is connected to the top of the well cavity, and a well cover that can be opened or closed is provided on the top of the well cylinder.

[0033] The beneficial effect of the above-mentioned further solutions is that by setting up well casings and well covers, subsequent inspection and maintenance can be facilitated. 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] As shown in Figures 1 to 3, a multi-stage energy dissipation drainage well includes a well cavity, a baffle mechanism, a slide rod transmission mechanism, a cover plate drive mechanism, a cover plate, a gear drive mechanism, a vertical stirring mechanism, and a horizontal stirring mechanism. The well cavity is divided by a partition into a baffle energy dissipation chamber 2, a water cushion energy dissipation chamber 3, a transition chamber 4, a stirring energy dissipation chamber 5, a power chamber, and an outlet chamber 8. The baffle energy dissipation chamber 2 is located at the upper part of the well cavity. The power chamber, water cushion energy dissipation chamber 3, transition chamber 4, and outlet chamber 8 are sequentially arranged adjacent to each other below the baffle energy dissipation chamber 2. The energy dissipation chamber 2 is connected to the water cushion energy dissipation chamber 3 and the water outlet chamber 8 respectively. The transition chamber 4 is horizontally adjacent to and connected to the water cushion energy dissipation chamber 3 and the water outlet chamber 8 respectively. The transition chamber 4 is vertically adjacent to and connected to the stirring energy dissipation chamber 5. The power chamber is adjacent to the baffle energy dissipation chamber 2, the water cushion energy dissipation chamber 3 and the stirring energy dissipation chamber 5 respectively. The upper part of the side wall of the baffle energy dissipation chamber 2 away from the water outlet chamber 8 is connected to the water inlet pipe 9. The bottom of the side wall of the water outlet chamber 8 away from the transition chamber 4 is connected to the water outlet pipe 10.

[0041] The baffle mechanism is installed inside the baffle energy dissipation chamber 2, and the gear drive mechanism is installed inside the power chamber. The slide rod transmission mechanism is installed in both the baffle energy dissipation chamber 2 and the power chamber, with the upper end of the slide rod transmission mechanism connected to the baffle mechanism and the lower end connected to the gear drive mechanism. The vertical stirring mechanism is installed in both the water cushion energy dissipation chamber 3 and the power chamber, and the horizontal stirring mechanism is installed in both the stirring energy dissipation chamber 5 and the power chamber. The gear drive mechanism is connected to both the vertical and horizontal stirring mechanisms and can drive them to rotate. The top of the cover plate drive mechanism is fixedly installed on the inner top wall of the baffle energy dissipation chamber 2, and the bottom of the cover plate drive mechanism is connected to the corresponding cover plates that are slidably installed in the connecting channels between the baffle energy dissipation chamber 2 and the water cushion energy dissipation chamber 3, between the water cushion energy dissipation chamber 3 and the transition chamber 4, and between the transition chamber 4 and the stirring energy dissipation chamber 5. The cover plate can be driven to slide up and down to open or close the corresponding connecting channels.

[0042] The upstream water flow discharged into the baffle energy dissipation chamber 2 through the water inlet pipe 9 first dissipates energy through the baffle mechanism. During this process, the baffle mechanism is driven to move, thereby pulling the slide rod transmission mechanism to move, which in turn drives the gear drive mechanism to rotate, thereby driving the vertical stirring mechanism and the horizontal stirring mechanism to rotate respectively. The rotation of the vertical stirring mechanism will agitate the water flow in the water cushion energy dissipation chamber 3 to enhance the energy dissipation effect of the water cushion. The rotation of the horizontal stirring mechanism will agitate and dissipate the water flow entering the stirring energy dissipation chamber 5.

[0043] Simultaneously, as the volume of water flowing from the upstream of the inlet pipe 9 into the baffle energy dissipation chamber 2 changes, the water level in the baffle energy dissipation chamber 2 changes, thereby driving the cover plate driving mechanism to move. This can then drive the cover plate at the connecting channel between the baffle energy dissipation chamber 2 and the water cushion energy dissipation chamber 3 to slide up and down, thereby opening or closing the connecting channel between the baffle energy dissipation chamber 2 and the water cushion energy dissipation chamber 3, driving the cover plate at the connecting channel between the water cushion energy dissipation chamber 3 and the transition chamber 4 to slide up and down, thereby opening or closing the connecting channel between the water cushion energy dissipation chamber 3 and the transition chamber 4, and driving the cover plate at the connecting channel between the transition chamber 4 and the stirring energy dissipation chamber 5 to slide up and down, thereby opening or closing the connecting channel between the transition chamber 4 and the stirring energy dissipation chamber 5.

[0044] The multi-stage energy dissipation drainage energy dissipation well of the present invention, by setting a baffle mechanism in the baffle energy dissipation chamber 2, can block and dissipate energy when the water flow entering the baffle energy dissipation chamber 2 falls. At the same time, during the energy dissipation process, the baffle mechanism can drive the slide rod transmission mechanism to move downward, thereby driving the gear drive mechanism to rotate, which in turn drives the vertical stirring mechanism and the horizontal stirring mechanism to rotate. In this way, the water flow in the water cushion energy dissipation chamber 3 and the stirring energy dissipation chamber 5 can be stirred and dissipated. Meanwhile, the cover plate drive mechanism can also automatically switch to the energy dissipation mode of first-stage, second-stage, or third-stage energy dissipation according to the water level changes in the baffle energy dissipation chamber 2 caused by the change in the upstream water volume. This effectively improves the adaptability of the drainage energy dissipation well to changes in the water volume, realizes differentiated energy dissipation according to different water volumes, and simultaneously realizes multi-stage energy dissipation of the water flow, thereby improving the energy dissipation efficiency.

[0045] In one or more embodiments of the present invention, a horizontal upper partition 44 connected to the bottom of the water inlet pipe 9 is provided on the upper part of the baffle energy dissipation chamber 2 near the water inlet pipe 9. The baffle energy dissipation chamber 2 is vertically separated from the power chamber, the water cushion energy dissipation chamber 3, the transition chamber 4, and the water outlet chamber 8 by a horizontal middle partition 45 provided at the bottom of the baffle energy dissipation chamber 2. The water cushion energy dissipation chamber 3 is vertically separated from the power chamber, and the transition chamber 4 is vertically separated from the stirring energy dissipation chamber 5 by a horizontal lower partition 46 provided at the lower part of the well cavity. The upper end of the baffle mechanism is connected to the bottom of the horizontal upper partition 44, and the lower end of the baffle mechanism is connected to the top of the horizontal middle partition 45. The horizontal middle partition 45 is provided with a primary orifice 22 connecting the baffle energy dissipation chamber 2 and the water cushion energy dissipation chamber 3, and a baffle energy dissipation chamber outlet 25 connecting the baffle energy dissipation chamber 2 and the water outlet chamber 8. A primary well 21 is connected below the primary orifice 22. The baffle energy dissipation chamber 2 and the water cushion energy dissipation chamber 3 are connected by the primary orifice 22 and the primary well. The first connecting channel formed by the cylinder 21 is connected. A first-stage cover plate 17 is slidably disposed inside the first-stage well cylinder 21. The bottom of the cover plate driving mechanism is connected to the top of the first-stage cover plate 17. The movement of the cover plate driving mechanism can drive the first-stage cover plate 17 to slide up and down inside the first-stage well cylinder 21, thereby opening or closing the first connecting channel formed between the baffle energy dissipation chamber 2 and the water cushion energy dissipation chamber 3 through the first-stage orifice 22 and the first-stage well cylinder 21. A connection between the transition chamber 4 and the stirring chamber is provided on the horizontal lower partition 46. The energy dissipation chamber 5 has a secondary orifice 24, and a secondary shaft 23 is connected below the secondary orifice 24. The transition chamber 4 and the stirring energy dissipation chamber 5 are connected through a second connecting channel formed by the secondary orifice 24 and the secondary shaft 23. A secondary cover plate 20 is slidably disposed inside the secondary shaft 23. The bottom of the cover plate driving mechanism is connected to the top of the secondary cover plate 20. The movement of the cover plate driving mechanism can drive the secondary cover plate 20 to slide up and down inside the secondary shaft 23 to open or close the second connecting channel.

[0046] The power chamber has an L-shaped cross-section. It is horizontally separated from the water cushion energy dissipation chamber 3 by a vertical first partition 47 and from the stirring energy dissipation chamber 5 by a vertical fourth partition 50. The side of the water cushion energy dissipation chamber 3 furthest from the power chamber is horizontally separated from the transition chamber 4 by a vertical second partition 48. The vertical second partition 48 has an upper opening 26 at its center connecting the water cushion energy dissipation chamber 3 and the transition chamber 4, and a lower opening 27 at its bottom connecting the two chambers. The water cushion energy dissipation chamber 3 and the transition chamber 4 are connected by an upper connecting channel formed by the upper opening 26 and the lower opening 27, respectively. A middle cover plate 19 is slidably mounted on the vertical second partition 48. Within the transition chamber 4 (or alternatively within the water cushion energy dissipation chamber 3), the bottom of the cover plate driving mechanism is connected to the top of the middle cover plate 19. The movement of the cover plate driving mechanism can cause the middle cover plate 19 to slide up and down on the vertical second partition 48, thereby opening or closing the bottom connecting channel. The side of the transition chamber 4 away from the water cushion energy dissipation chamber 3 is horizontally separated from the water outlet chamber 8 by a vertical third partition 49. The bottom of the vertical third partition 49 is provided with a transition chamber water outlet hole 28 connecting the transition chamber 4 and the water outlet chamber 8. The side of the stirring energy dissipation chamber 5 away from the power chamber is horizontally separated from the water outlet chamber 8 by a vertical fifth partition 51. The bottom of the vertical fifth partition 51 is provided with a stirring energy dissipation chamber water outlet hole 29 connecting the stirring energy dissipation chamber 5 and the water outlet chamber 8.

[0047] The power chamber is divided into a drive chamber 6 and a gear transmission chamber 7. The drive chamber 6 is located below the baffle energy dissipation chamber 2 and is separated from the baffle energy dissipation chamber 2 by the horizontal middle partition 45. The gear transmission chamber 7 is located below the water cushion energy dissipation chamber 3 and is separated from the water cushion energy dissipation chamber 3 by the horizontal lower partition 46. The drive chamber 6 is located on the same side of the water cushion energy dissipation chamber 3 and the gear transmission chamber 7 (the side away from the transition chamber 4). The upper part of the drive chamber 6 is horizontally separated from the water cushion energy dissipation chamber 3 by the vertical first partition 47, and the lower part of the drive chamber 6 is completely connected to the gear transmission chamber 7. The side of the gear transmission chamber 7 away from the drive chamber 6 is horizontally separated from the stirring energy dissipation chamber 5 by the vertical fourth partition 50.

[0048] The well cavity is divided into different chambers by the horizontal upper partition 44, horizontal middle partition 45, horizontal lower partition 46, vertical first partition 47, vertical second partition 48, vertical third partition 49, vertical fourth partition 50 and vertical fifth partition 51. On the one hand, it can facilitate the synchronous and coordinated operation of multiple drive mechanisms. On the other hand, it can achieve multi-stage energy dissipation by opening or closing different water flow channels, thereby improving energy dissipation efficiency.

[0049] In one or more embodiments of the present invention, a water distribution plate 53 is provided on the top of the horizontal upper partition 44 on the side away from the water inlet pipe 9, and water distribution holes are evenly distributed on the water distribution plate 53. By providing the water distribution plate 53 and the water distribution holes, the upstream water entering the baffle energy dissipation chamber 2 can be evenly distributed to stabilize the outflow of water.

[0050] In one or more embodiments of the present invention, the cover plate driving mechanism includes a float 13, a pull rope 14, two fixed pulleys 15, a rod assembly 16, and a spring 18. The two fixed pulleys 15 are spaced apart on the inner top wall of the baffle energy dissipation chamber 2. The float 13 is disposed in the baffle energy dissipation chamber 2 and located between the water inlet pipe 9 and the water distribution plate 53. One end of the pull rope 14 is connected to the top of the float 13, and the other end of the pull rope 14 passes around the two fixed pulleys 15 and is connected to the top of the rod assembly 16. The bottom of the rod assembly 16 is connected to the top of the primary cover plate 17, the upper end of the spring 18, and the secondary cover plate 20, respectively. The top connection is made so that the lower end of the spring 18 is connected to the top of the middle cover plate 19. The change in the amount of water from the upstream water discharged by the water inlet pipe 9 can cause the water level in the baffle energy dissipation chamber 2 to change, thereby driving the float 13 to move up and down, which in turn drives the pull rope 14 to move, and then drives the rod assembly 16 to move up and down. The up and down movement of the rod assembly 16 respectively drives the first-stage cover plate 17 to slide up and down in the first-stage well shaft 21, the middle cover plate 19 to slide up and down on the vertical second partition 48, and the second-stage cover plate 20 to slide up and down in the second-stage well shaft 23, so as to open or close the first connecting channel, the bottom connecting channel, and the second connecting channel respectively. By setting the float 13, when the upstream water volume changes, the float 13 moves up and down, thereby pulling the pull rope 14 up and down and driving the rod assembly 16 to move up and down. This in turn drives the first-stage cover plate 17 to slide up and down in the first-stage well shaft 21, the middle cover plate 19 to slide up and down on the vertical second partition 48, and the second-stage cover plate 20 to slide up and down in the second-stage well shaft 23. The first-stage cover plate 17 slides up and down in the first-stage well shaft 21 to open or close the first connecting channel; the middle cover plate 19 slides up and down to open or close the bottom connecting channel; and the second-stage cover plate 20 slides up and down in the second-stage well shaft 23 to open or close the second connecting channel. This achieves automatic switching of energy dissipation mode and improves the adaptability of the drainage energy dissipation well to changes in upstream water volume.

[0051] In one or more embodiments of the present invention, the rod assembly 16 includes a horizontal rod 54 and three vertical rods 55. The top of the horizontal rod 54 is connected to one end of the pull rope 14, and the bottom of the horizontal rod 54 is connected to the upper ends of the three vertical rods 55. The lower ends of the three vertical rods 55 are connected to the top of the primary cover plate 17, the upper end of the spring 18, and the top of the secondary cover plate 20, respectively. Through the horizontal rod 54 and the three vertical rods 55, the pull rope 14 can drive the three vertical rods 55 to move up and down via the horizontal rod 54, thereby causing the primary cover plate 17, the middle cover plate 19, and the secondary cover plate 20 to slide up and down, thus realizing the opening or closing of different connecting channels and completing the switching of different energy dissipation modes.

[0052] In one or more embodiments of the present invention, the baffle mechanism is composed of multiple vertically arranged baffle springs 12 and multiple horizontally arranged baffles 11 connected alternately in a vertical manner. The upper end of the first baffle spring 12 from top to bottom is connected to the bottom of the horizontal upper partition 44, and the lower end of the first baffle spring 12 from top to bottom is connected to the top of the first baffle 11 from top to bottom. The upper ends of each of the middle baffle springs 12 are connected to the bottom of the corresponding baffle 11 above them, and the lower ends of each of the middle baffle springs 12 are connected to the top of the corresponding baffle 11 below them. The upper end of the last baffle spring 12 is connected to the bottom of the last baffle 11 above it from top to bottom, and the lower end of the last baffle spring 12 is connected to the top of the horizontal middle partition 45. The upper end of the slide rod transmission mechanism is connected to the bottom of the first baffle 11 from top to bottom. Multiple baffle springs 12 and multiple horizontally arranged baffles 11 are alternately connected vertically. In this way, the upstream water flowing into the baffle energy dissipation chamber 2 through the water inlet pipe 9 flows downward and impacts each baffle 11 to dissipate energy. At the same time, each baffle 11 moves downward under the impact of the water flow, thereby compressing or stretching the corresponding baffle springs 12 downward, which in turn pulls the first baffle 11 downward, causing the slide rod transmission mechanism to move downward, which in turn drives the gear drive mechanism to rotate, thereby driving the vertical stirring mechanism and the horizontal stirring mechanism to rotate.

[0053] In one or more embodiments of the present invention, the slide bar transmission mechanism includes a vertical guide rod 36, a fixed plate 37, a movable rod 38, an L-shaped rotating connecting rod 39, and a rotating ring 40. The upper end of the vertical guide rod 36 is connected to the bottom of the first baffle 11 from top to bottom. At least two rod sleeves 43 are provided on the inner wall of the drive chamber 6 near the water inlet pipe 9. The middle part of the vertical guide rod 36 is sleeved in the rod sleeve 43. The fixed plate 37 is fixedly provided on the lower part of the vertical guide rod 36. One end of the movable rod 38 is movably connected to the fixed plate 37. The other end of the movable rod 38 is connected to one end of the rotating connecting rod 39. The other end of the rotating connecting rod 39 is connected to the outer wall of the rotating ring 40. 0 is connected to the gear drive mechanism. When the upstream water flowing from the water inlet pipe 9 into the baffle energy dissipation chamber 2 falls downward and impacts each of the baffles 11 to dissipate energy, each of the baffles 11 moves downward under the impact of the water flow, thereby compressing or stretching the corresponding baffle springs 12 downward, and then pulling the first baffle 11 downward to drive the vertical guide rod 36 to slide downward. When the vertical guide rod 36 slides downward, it drives the movable rod 38 to rotate through the fixed plate 37. The rotation of the movable rod 38 drives the rotating connecting rod 39 to rotate, which in turn drives the rotating ring 40 to rotate. The rotation of the rotating ring 40 drives the gear drive mechanism to rotate, which in turn drives the vertical stirring mechanism and the horizontal stirring mechanism to rotate respectively. Under the impact of the water flow, the vertical guide rod 36 is driven to slide downward by the first baffle 11 from top to bottom. In this way, the movable rod 38, the rotating connecting rod 39 and the connecting ring 40 are driven to move sequentially through the fixed plate 37, thereby driving the gear drive mechanism to rotate, and then driving the vertical stirring mechanism and the horizontal stirring mechanism to rotate, thereby stirring and dissipating the water flow in the water cushion energy dissipation chamber 3 and the stirring energy dissipation chamber 5.

[0054] In one or more embodiments of the present invention, the gear drive mechanism includes a drive gear 42, an upper gear 30, a middle gear 33, and a gear shaft 41. The upper gear 30 is located above the drive gear 42, and the middle gear 33 is located in the middle of the drive gear 42 near the stirring and energy dissipation chamber 5. The drive gear 42 meshes with the upper gear 30 and the middle gear 33 respectively. One end of the gear shaft 41 is connected to the center of the drive gear 42, and the other end of the gear shaft 41 is connected to the rotating ring 40. When the rotating ring 40 rotates, it can drive the gear shaft 41 to rotate, thereby driving the drive gear 42 to rotate, thus driving the upper gear 30 and the middle gear 33 to rotate, and thus driving the vertical stirring mechanism and the horizontal stirring mechanism to rotate. By setting the drive gear 42 to mesh with the upper gear 30 and the middle gear 33 respectively, when the drive gear 42 rotates, the drive gear 42 can drive the upper gear 30 and the middle gear 33 to rotate respectively. This can drive the vertical stirring mechanism and the horizontal stirring mechanism to rotate respectively, so as to achieve stirring and energy dissipation of the water flow in the water cushion energy dissipation chamber 3 and the stirring energy dissipation chamber 5.

[0055] In one or more embodiments of the present invention, the vertical stirring mechanism includes a vertical rotating shaft 31 and multiple vertical shaft stirring blades 32. The vertical rotating shaft 31 is vertically arranged in the water cushion energy dissipation chamber 3 and the gear transmission chamber 7, and the lower end of the vertical rotating shaft 31 is connected to the top center of the upper gear 30. Each of the vertical shaft stirring blades 32 is located in the water cushion energy dissipation chamber 3 and is arranged vertically at intervals on the upper part of the vertical rotating shaft 31.

[0056] The horizontal stirring mechanism includes a horizontal rotating shaft 34 and multiple horizontal shaft stirring blades 35. The horizontal rotating shaft 34 is horizontally arranged in the stirring energy dissipation chamber 5 and the gear transmission chamber 7, and the end of the horizontal rotating shaft 34 near the middle gear 33 is connected to the center of the side of the middle gear 33. Each of the horizontal shaft stirring blades 35 is located in the stirring energy dissipation chamber 5 and is arranged on the horizontal rotating shaft 34 at left and right intervals.

[0057] The drive gear 42 can simultaneously drive the vertical shaft 31 and the horizontal shaft 34 to rotate via the upper gear 30 and the middle gear 33, respectively, so as to drive the vertical shaft stirring plate 32 and the horizontal shaft stirring plate 35 to rotate, thereby stirring and dissipating the water flow entering the water pad energy dissipation chamber 3 and the stirring energy dissipation chamber 5, respectively.

[0058] The upstream water flowing into the baffle energy dissipation chamber 2 through the inlet pipe 9 falls downwards, impacting each of the baffles 11 to dissipate energy. During this process, each baffle 11 moves downwards under the impact of the water flow, thereby compressing or stretching the corresponding baffle springs 12 downwards, which in turn pulls the first baffle 11 downwards. This causes the vertical guide rod 36 to slide downwards. The downward sliding of the vertical guide rod 36 drives the movable rod 38 to rotate through the fixed plate 37. The rotation of the movable rod 38 drives the rotating connecting rod 39 to rotate, which in turn drives the rotating ring 40 to rotate, causing the gear shaft 41 to rotate. The drive gear 42 is driven to rotate, thereby driving the upper gear 30 and the middle gear 33 to rotate through meshing. The rotation of the upper gear 30 drives the vertical shaft 31 to rotate, which in turn drives the vertical shaft stirring plate 32 to rotate. The rotation of each vertical shaft stirring plate 32 agitates the water flow in the water cushion energy dissipation chamber 3 to enhance the energy dissipation effect of the water cushion. The rotation of the middle gear 33 drives the horizontal shaft 34 to rotate, which in turn drives the horizontal shaft stirring plate 35 to rotate. The rotation of each horizontal shaft stirring plate 35 agitates and dissipates the water flow entering the stirring energy dissipation chamber 5 from the transition chamber 4, effectively realizing staged energy dissipation and improving energy dissipation efficiency.

[0059] Optionally, in one or more embodiments of the present invention, a well casing 1 is connected to the top of the well cavity, and a manhole cover 52 that can be opened or closed is provided on the top of the well casing 1. By providing the well casing 1 and the manhole cover 52, subsequent inspection and maintenance can be facilitated.

[0060] The operation of the multi-stage energy dissipation drainage energy dissipation well of the present invention is as follows:

[0061] Before water arrives in the upstream drainage pipe, the cover plate drive mechanism, the primary cover plate 17, the middle cover plate 19, the secondary cover plate 20, the baffle mechanism, the slide rod transmission mechanism, the gear drive mechanism, the vertical stirring mechanism, and the horizontal stirring mechanism are all in their initial state, i.e., each of the baffle springs 12 and the springs 18 are in their natural state; the primary cover plate 17 is located inside the primary shaft 21, the secondary cover plate 20 is located inside the secondary shaft 23, and the middle cover plate 19 does not cover the lower orifice 27. That is, the upper part and the bottom of the water cushion energy dissipation chamber 3 are open to the transition chamber 4 through the upper orifice 26 and the lower orifice 27, respectively. The slide rod transmission mechanism does not move up and down, and the gear drive mechanism, the vertical stirring mechanism, and the horizontal stirring mechanism do not rotate.

[0062] When water flows into the upstream drainage pipe and is discharged into the baffle energy dissipation chamber 2 through the inlet pipe 9, the water flow causes the water level in the baffle energy dissipation chamber 2 between the inlet pipe 9 and the water distribution plate 53 to rise. This rise in water level causes the float 13 to float upwards, which in turn causes the pull rope 14 to slide. Under the influence of gravity, the horizontal rod 54 moves downwards, causing the three vertical rods 55 to move downwards. The downward movement of the vertical rods 55 causes the first-stage cover plate 17 to slide downwards within the first-stage well shaft 21, the middle cover plate 19 to slide downwards, and the second-stage cover plate 20 to slide downwards within the second-stage well shaft 23. Since the water flow from the upstream drainage pipe has not reached the set flow rate... Consequently, the water level in the corresponding baffle energy dissipation chamber 2 has not reached the set value, so the float 13 has not risen to the set height. Consequently, the primary cover 17 is still inside the primary shaft 21, the middle cover 19 is still not completely covering the lower orifice 27, and the secondary cover 20 is still inside the secondary shaft 23. Therefore, the first connecting channel formed between the baffle energy dissipation chamber 2 and the water cushion energy dissipation chamber 3 through the primary orifice 22 and the primary shaft 21 remains closed. The upper connecting channel and the bottom connecting channel between the water cushion energy dissipation chamber 3 and the transition chamber 4 remain open. The second connecting channel formed between the transition chamber 4 and the stirring energy dissipation chamber 5 through the secondary orifice 24 and the secondary shaft 23 remains closed. Therefore, the upstream water flow entering the baffle energy dissipation chamber 2 is stabilized through the water distribution holes on the water distribution plate 53 and then flows out. The water flows down and impacts each of the baffles 11 to dissipate energy. The dissipated water flows into the outlet chamber 8 through the outlet holes 25 of the baffle energy dissipation chamber 2, and then flows into the downstream drainage pipe through the outlet pipe 10.

[0063] When the water flow in the upstream drainage pipe continues to increase and reaches a certain set flow rate, it is discharged into the baffle energy dissipation chamber 2 through the inlet pipe 9. This causes the water level in the baffle energy dissipation chamber 2 between the inlet pipe 9 and the water distribution plate 53 to rise to a certain set height. Correspondingly, the float 13 rises to a certain set height. The first-stage cover plate 17 is just below the bottom of the first-stage well 21, but the middle cover plate 19 has not completely covered the lower orifice 27. The second-stage cover plate 20 is still inside the second-stage well 23. Therefore, the first connecting channel formed by the baffle energy dissipation chamber 2 and the water cushion energy dissipation chamber 3 through the first-stage orifice 22 and the first-stage well 21 is open. The upper connecting channel between the water cushion energy dissipation chamber 3 and the transition chamber 4 is still open, and the bottom connecting channel is partially open. The second connecting channel formed by the second-stage orifice 24 and the second-stage well 23 between the transition chamber 4 and the stirring energy dissipation chamber 5 is still closed. Therefore, the upstream water flow entering the baffle energy dissipation chamber 2 is stabilized through the water distribution holes on the water distribution plate 53 and then flows out. The outflowing water falls downwards and impacts each of the baffles 11 to dissipate energy. The dissipated water flows sequentially into the water cushion energy dissipation chamber 3 through the first connecting channel formed by the first-stage orifice 22 and the first-stage well 21, and then enters the transition chamber 4 through the bottom connecting channel formed by the lower orifice 27. After that, it is discharged into the outlet chamber 8 through the outlet hole 28 of the transition chamber, and then discharged into the downstream drainage pipe through the outlet pipe 10.

[0064] When the water flow in the upstream drainage pipe continues to increase to another set flow rate, it is discharged into the baffle energy dissipation chamber 2 through the inlet pipe 9, thereby causing the water level in the baffle energy dissipation chamber 2 between the inlet pipe 9 and the water distribution plate 53 to rise to another set height. Correspondingly, the float 13 rises to another set height, and the corresponding primary cover plate 17 is still below the bottom of the primary well 21. The middle cover plate 19 just completely covers the lower orifice 27, but the secondary cover plate 20 is still inside the secondary well 23. Therefore, the first connecting channel formed between the baffle energy dissipation chamber 2 and the water cushion energy dissipation chamber 3 through the primary orifice 22 and the primary well 21 is still open. The bottom connecting channel formed between the water cushion energy dissipation chamber 3 and the transition chamber 4 through the lower orifice 27 is closed, but the upper connecting channel formed through the upper orifice 26 is still open. The second connecting channel formed between the transition chamber 4 and the stirring energy dissipation chamber 5 through the secondary orifice 24 and the secondary well 23 is still closed. Therefore, the upstream water flowing into the baffle energy dissipation chamber 2 flows out after being stabilized by the water distribution holes on the water distribution plate 53. The water then falls downwards and impacts each of the baffles 11 to dissipate energy. After energy dissipation, the water flows into the water cushion energy dissipation chamber 3 through the first connecting channel formed by the first-stage orifice 22 and the first-stage well 21, causing the water level in the water cushion energy dissipation chamber 3 to rise rapidly until the water level in the water cushion energy dissipation chamber 3 reaches the bottom of the upper orifice 26. After that, the water flows into the transition chamber 4 from the upper orifice 26 and is discharged into the outlet chamber 8 through the transition chamber outlet hole 28. Subsequently, it is discharged into the downstream drainage pipe through the outlet pipe 10. Subsequently, the upstream water flowing into the baffle energy dissipation chamber 2 flows out after being stabilized through the water distribution holes on the water distribution plate 53. The outflowing water falls downwards and impacts each of the baffles 11 to dissipate energy. After energy dissipation, the water flows sequentially into the water cushion energy dissipation chamber 3 through the first connecting channel formed by the first-stage orifice 22 and the first-stage well 21. Water accumulates in the space between the bottom of the upper orifice 26 and the bottom of the lower orifice 27 in the water cushion energy dissipation chamber 3. This accumulated water forms a water cushion layer, which allows the water falling from the baffle energy dissipation chamber 2 into the water cushion energy dissipation chamber 3 and impacting the water cushion layer in the water cushion energy dissipation chamber 3 to dissipate energy.Meanwhile, as the upstream water flowing into the baffle energy dissipation chamber 2 through the inlet pipe 9 falls downwards and impacts each of the baffles 11 to dissipate energy, each of the baffles 11 moves downwards under the impact of the water flow, thereby compressing or stretching the corresponding baffle springs 12 downwards. This pulls the first baffle 11 downwards, causing the vertical guide rod 36 to slide downwards. The vertical guide rod 36 slides downwards and drives the movable rod 38 to rotate through the fixed plate 37. The rotation of the movable rod 38 drives the rotating connecting rod 39 to rotate, which in turn drives the rotating ring 40 to rotate, causing the gear shaft 41 to rotate. The rotation of the gear shaft 41 drives the gear 42 to rotate, thereby driving the upper gear 30 to rotate through meshing. The rotation of the upper gear 30 can sequentially drive the vertical shaft 31 and each of the vertical shaft stirring plates 32 to rotate. The rotation of each vertical shaft stirring plate 32 agitates the water in the water cushion energy dissipation chamber 3 to enhance the energy dissipation effect of the water cushion. During this process, the upstream water flow entering the baffle energy dissipation chamber 2 is stabilized through the water distribution holes on the water distribution plate 53 and then exits. The exiting water flow undergoes two stages of energy dissipation in sequence. The first stage of energy dissipation is achieved by the water falling downwards and impacting each of the baffles 11 in the baffle energy dissipation chamber 2. The second stage of energy dissipation is achieved by the water cushion layer falling from the baffle energy dissipation chamber 2 into the water cushion energy dissipation chamber 3 and impacting the water cushion layer in the water cushion energy dissipation chamber 3. The energy dissipation effect of the second stage of energy dissipation is enhanced by the stirring action of each of the vertical shaft stirring plates 32.

[0065] When the water flow in the upstream drainage pipe continues to increase and reaches another set flow rate, the water is discharged into the baffle energy dissipation chamber 2 through the inlet pipe 9. This causes the water level in the baffle energy dissipation chamber 2 between the inlet pipe 9 and the water distribution plate 53 to rise to another set height. Correspondingly, the float 13 also rises to another set height. The corresponding primary cover plate 17 is still located below the bottom of the primary shaft 21. Because the vertical rod 55 compresses the spring 18, the middle cover plate 19 still completely covers the lower orifice 27. The secondary cover plate 20 is just below the bottom of the secondary shaft 23. Therefore, the first connecting channel formed between the baffle energy dissipation chamber 2 and the water cushion energy dissipation chamber 3 through the primary orifice 22 and the primary shaft 21 is still open. The bottom connecting channel between the water cushion energy dissipation chamber 3 and the transition chamber 4 is still closed, but the upper connecting channel is still open. The second connecting channel formed between the transition chamber 4 and the stirring energy dissipation chamber 5 through the secondary orifice 24 and the secondary shaft 23 is open. Therefore, the upstream water flow entering the baffle energy dissipation chamber 2 is stabilized through the water distribution holes on the water distribution plate 53 and then flows out. The outflowing water falls downwards and impacts each of the baffles 11 for the first stage of energy dissipation. The dissipated water then flows sequentially through the first connecting channel formed by the first-stage orifice 22 and the first-stage well 21 into the water cushion energy dissipation chamber 3 and impacts the water cushion layer in the water cushion energy dissipation chamber 3 for the second stage of energy dissipation. The dissipated water then enters the transition chamber 4 through the upper orifice 26 and falls from the transition chamber 4 through the second connecting channel formed by the second-stage orifice 24 and the second-stage well 23 into the stirring energy dissipation chamber 5. The water then undergoes energy dissipation through the horizontal stirring mechanism. The dissipated water then flows through the outlet hole 29 of the stirring energy dissipation chamber into the outlet chamber 8, and then through the outlet pipe 10 into the downstream drainage pipe.Meanwhile, as the upstream water flowing into the baffle energy dissipation chamber 2 from the inlet pipe 9 falls downwards and impacts each of the baffles 11 to dissipate energy, each baffle 11 moves downwards under the impact of the water flow, thereby compressing or stretching the corresponding baffle springs 12 downwards. This pulls the first baffle 11 downwards, causing the vertical guide rod 36 to slide downwards. The downward sliding of the vertical guide rod 36 drives the movable rod 38 to rotate through the fixed plate 37. The rotation of the movable rod 38 drives the rotating connecting rod 39 to rotate, which in turn drives the rotating ring 40 to rotate and causes the gear shaft 41 to rotate. The rotation of the gear shaft 41 drives the gear 42 to rotate, thereby driving the upper gear 30 and the middle gear 33 to rotate through meshing. The rotation of the upper gear 30 can drive the vertical shaft 31 to rotate, which in turn drives the vertical shaft stirring plate 32 to rotate. The rotation of each vertical shaft stirring plate 32 can agitate the water in the water cushion energy dissipation chamber 3 to enhance the energy dissipation effect of the water cushion. The rotation of the middle gear 33 can drive the horizontal shaft 34 to rotate, which in turn drives the horizontal shaft stirring plate 35 to rotate. The rotation of each horizontal shaft stirring plate 35 can agitate and dissipate the water flow entering the stirring energy dissipation chamber 5 from the transition chamber 4. During this process, the upstream water flow entering the baffle energy dissipation chamber 2 is stabilized through the water distribution holes on the water distribution plate 53 and then exits. The exiting water flow undergoes three stages of energy dissipation in sequence: the first stage of energy dissipation is achieved by the water falling downwards and impacting each of the baffles 11 in the baffle energy dissipation chamber 2; the second stage of energy dissipation is achieved by the water cushion layer falling from the baffle energy dissipation chamber 2 into the water cushion energy dissipation chamber 3 and impacting the water cushion layer in the water cushion energy dissipation chamber 3, and the agitation effect of the water cushion in the second stage of energy dissipation is enhanced by the agitation of each of the vertical shaft stirring plates 32; the third stage of energy dissipation is achieved by the agitation of the water flow falling from the transition chamber 4 into the stirring energy dissipation chamber 5 by the agitation of the horizontal shaft stirring plates 35.

[0066] When the upstream drainage pipe stops receiving water, the water stored in the baffle energy dissipation chamber 2 flows out through the water distribution holes on the water distribution plate 53 after being stabilized. It then passes sequentially through the water cushion energy dissipation chamber 3, the transition chamber 4, and the stirring energy dissipation chamber 5 before being discharged from the outlet chamber 8. During this process, the water level in the baffle energy dissipation chamber 2 gradually decreases, causing the float 13 to descend. This pulls the rope 14, causing it to slide, which in turn moves the horizontal rod 54 upwards, which in turn moves the three vertical rods 55 upwards. The upward movement of the vertical rods 55 causes the first-stage cover plate 17 to slide upwards within the first-stage well shaft 21, the middle cover plate 19 to slide upwards, and the second-stage cover plate 20 to slide upwards within the second-stage well shaft 21. The upward sliding within 3 sequentially closes the first connecting channel formed by the primary orifice 22 and the primary well 21 between the baffle energy dissipation chamber 2 and the water cushion energy dissipation chamber 3, opens the upper connecting channel and the bottom connecting channel between the water cushion energy dissipation chamber 3 and the transition chamber 4, and closes the second connecting channel formed by the secondary orifice 24 and the secondary well 23 between the transition chamber 4 and the stirring energy dissipation chamber 5. This allows the water accumulated in the baffle energy dissipation chamber 2 and the water cushion energy dissipation chamber 3 to be discharged into the outlet chamber 8 through the corresponding baffle energy dissipation chamber outlet 25 and the first connecting channel, and then discharged into the downstream drainage pipe through the outlet pipe 10, thereby returning the system to its initial state.

[0067] Before the upstream drainage pipe receives water again, the cover plate drive mechanism, the primary cover plate 17, the middle cover plate 19, the secondary cover plate 20, the baffle mechanism, the slide rod transmission mechanism, the gear drive mechanism, the vertical stirring mechanism, and the horizontal stirring mechanism all return to their initial state, that is, each of the baffle springs 12 and the springs 18 are in their natural state; the primary cover plate 17 is located inside the primary shaft 21, the secondary cover plate 20 is located inside the secondary shaft 23, the middle cover plate 19 does not cover the lower orifice 27, that is, the upper part and the bottom of the water cushion energy dissipation chamber 3 are open to the upper and lower connecting channels of the transition chamber 4 through the upper orifice 26 and the lower orifice 27, respectively; the slide rod transmission mechanism does not move up and down; and each of the gear drive mechanisms, the vertical stirring mechanism, and the horizontal stirring mechanism does not rotate.

[0068] 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.
