Description

Technical Field

[0001] This invention relates to the field of dams, and more specifically to a movable landscape dam. Background Technology

[0002] Hydraulically driven movable dams with landscape hinges are low-head water-retaining structures. They often use hydraulic cylinders to directly drive the dam face, meaning one end of the hydraulic cylinder is connected to the dam body and the other end is connected to the foundation. Traditional movable dams include: sluice gates, rubber dams, flap gate dams, steel dam gates, and pneumatic gates.

[0003] Existing technologies also include movable dams that can withstand the impact of water flow, which can also form a landscape for people to enjoy.

[0004] However, existing movable dams generally use elastic components and suspended weights to resist impact forces. After a long period of use, the impact resistance of elastic components decreases, and the method of suspending weights is also less effective in resisting impacts because the weights are buoyant in the water. In addition, the weights also occupy a certain amount of space, affecting the mobility of the movable dam.

[0005] In addition, although the existing landscape dams can spray water, the effect of the water spray landscape is poor. The water sprays of multiple dams are independent of each other and do not form a large landscape effect. Summary of the Invention

[0023] (III) Beneficial Effects

[0024] This invention provides a movable landscape dam. Compared with the prior art, it has the following advantages:

[0025] 1. By setting up the impact plate and pressurization components, the impact of water flow can be reduced through air pressure buffering. Moreover, the air pressure buffering effect is ideal and still has a good buffering effect after a long period of use.

[0026] 2. By using air pressure to push the push block and sealing rod to move, the water in the drainage chamber is squeezed and the water is sprayed out from the nozzle through the conduit, thus forming a fountain. The spray direction can be changed according to the angle of the dam, thus creating a better landscape effect.

[0027] 3. By installing solenoid valves, the fountain can be more easily controlled by humans when it sprays, resulting in a better landscape effect. Furthermore, the force of the fountain's spray comes from the impact of the water flow, which also has an energy-saving effect. Attached Figure Description

[0034] Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] This application provides a movable landscape dam that solves the problems of decreased buffering effect and unsatisfactory landscape attributes after prolonged use. It achieves buffering through air pressure, and the impact plate 9 also plays a guiding role when tilted, thereby reducing water flow impact. Even after prolonged use and when the internal air pressure becomes depleted, it still provides good buffering. The force of the water flow impact pressurizes the diversion chamber 3, propelling the water in the diversion chamber 3 to form a fountain from the nozzle 5, resulting in a better landscape effect.

[0037] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0038] When mechanical components that use springs, weights, etc. as the core for cushioning are used, the springs repeatedly expand and contract during use, gradually damaging their toughness and reducing their elasticity, thus weakening the cushioning effect.

[0039] As the impact proceeds, the internal pressure can be gradually increased by the impact force through the action of the first one-way valve 15, thereby providing power for the water jet.

[0040] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0041] Reference Figures 1-4A movable landscape dam includes a dam body 1 and a hydraulic rod 2. The movable end of the hydraulic rod 2 is rotatably connected to the side wall of the dam body 1. A diversion cavity 3 is provided inside the dam body 1. An inlet is provided on one side of the diversion cavity 3 along the water flow direction. A conduit 4 is connected to the other side of the diversion cavity 3. The bottom end of the conduit 4 is located above the inlet. The upper end of the conduit 4 extends to the upper end of the dam body 1 and is connected to a nozzle 5. A push block 6 is provided in the diversion cavity 3. The push block 6 is movably sealed to the inner wall of the diversion cavity 3. The upper side wall of the push block 6 is set to be movable below the upper side wall of the inlet. An opening is provided at the bottom of the diversion cavity 3. One end of the opening is connected to the diversion cavity 3. The other end of the opening extends to the side of the dam body 1 near the water flow direction. A vertical sealing rod 7 is connected to the lower side wall of the push block 6. The sealing rod 7 is movably sealed to the opening. A solenoid valve 8 is provided at the lower end of the opening.

[0042] A pressurizing component is installed on the side of the dam body 1 closest to the direction of water flow. An impact plate 9 is rotatably connected to the side wall of the dam body 1, and the impact plate 9 is connected to the pressurizing component.

[0043] When using the landscape dam, the dam body 1 is rotated by the hydraulic rod 2, a technique known to those skilled in the art. The inlet is located in the water, and water can enter the diversion chamber 3 through the inlet. When the impact plate 9 is impacted by the water flow, it can drive the connecting rod 11 to move. The connecting rod 11 drives the push rod 12 to move, and the push rod 12 pushes the sealing piston 13 to move. When the sealing piston 13 moves, it can compress the pressurized space enclosed by the sealing piston 13, the sealing plate 14, and the pressurizing groove 10, and squeeze the gas in the pressurized space into the sealing space. The sealing space is enclosed by the pressurizing groove 10, the sealing plate 14, and the dam body 1. The gas enters the sealing space through the first one-way valve 15. As the gas increases, the gas pressure increases. The solenoid valve 8 controls the opening, and the gas can enter the opening, pushing the sealing rod 7 and the push block 6 to move upward. The push block 6 can push the water flow in the diversion chamber 3, and the water flow can be sprayed out from the nozzle 5 through the conduit 4 to form a fountain.

[0044] Reference Figure 2 In a further embodiment: the pressurization assembly includes a pressurization groove 10, which communicates with an opening and is fixedly sealed to the side wall of the dam body 1. A connecting rod 11 is rotatably connected to the side wall of the impact plate 9, and a push rod 12 is rotatably connected to the connecting rod 11. The push rod 12 passes through the side wall of the pressurization groove 10 and is movably sealed to the pressurization groove 10. A sealing piston 13 is provided in the pressurization groove 10, and the push rod 12 is connected to the sealing piston 13. A sealing plate 14 is fixedly connected in the pressurization groove 10 and is sealed to the pressurization groove 10. A first one-way valve 15 is provided on the side wall of the sealing plate 14. The direction of the first one-way valve 15 is from the sealing piston 13 to the solenoid valve 8. An air inlet pipe 16 is provided on the side wall of the sealing plate 14. The other end of the air inlet pipe 16 extends to the upper end of the dam body 1 and is connected to a second one-way valve 17.

[0045] When the sealed space is pressurized, the gas in the pressurized space is pushed into the sealed space, and the outside gas can enter the air inlet pipe 16 through the second one-way valve 17 and enter the pressurized space under the action of the air inlet pipe 16. When the gas pressure in the pressurized space is the same as that in the outside, the second one-way valve 17 automatically closes to prevent the gas in the pressurized space from flowing back out. This allows the pressurized space to continuously supply gas to the sealed space.

[0046] The second one-way valve 17 is installed at the top of the dam body 1 and can always be in contact with the outside world. When the dam body 1 is completely submerged in water, the impact plate 9 will be in a nearly horizontal state and will not be impacted by the water flow, thus preventing water from entering the pressurized space.

[0047] In a further embodiment, an electrical control unit 18 is also included. The electrical control unit 18 is used to be electrically connected to a plurality of dam bodies 1. The electrical control unit 18 includes a switch unit 19, which is electrically connected to a solenoid valve 8 in a plurality of dam bodies 1 and is used to control the opening or closing of the solenoid valve 8.

[0048] The solenoid valve 8 in the dam body 1 is controlled by the connection between the electrical control unit 18 and the switch unit 19. The switch unit 19 can also be remotely controlled, so that the fountain can be manually controlled in real time.

[0049] The switch unit 19 is used to send a switch signal. After the new signal is sent, the solenoid valve 8 can open, thereby causing the gas in the sealed space to push the push block 6 to move. An exhaust port 28 can be set in the dam body 1. The exhaust port 28 is zig-shaped, and the bottom end of the exhaust port 28 is connected to the opening. When the sealing rod 7 moves upward, it can move to the top of the exhaust port 28. In this way, the gas in the sealed space can be discharged through the exhaust port 28 after pushing the sealing rod 7 to move. A third one-way valve can be set at the other end of the exhaust port 28 to prevent water from entering the exhaust port 28. The position of the bottom end of the exhaust port 28 can be set to be below the height of the drainage cavity 3 when the sealing rod 7 moves to the lowest point. In this way, when the sealing rod 7 moves to the top, the opening is exactly connected to the exhaust port 28.

[0050] Reference Figure 4 In a further embodiment: the electronic control unit 18 further includes a landscape control unit 20, the landscape control unit 20 including:

[0051] Receive pressure preparation completion signals from multiple pressure measuring components in dam body 1;

[0052] The water spray signal is sent to the switch unit 19 according to the preset water spray effect.

[0053] By inputting different landscape effects into the landscape control unit 20, multiple dams 1 can exhibit better landscape effects when spraying water. For example, multiple dams 1 can be preset to spray water together, spray water in sequence, spray water in sequence with one or more intervals, spray water from the middle to both ends, and spray water from both ends to the middle.

[0054] In a further embodiment: the pressure measuring component is used to measure the pressure in the sealed space enclosed by the sealing plate 14, the dam body 1 and the pressurization groove 10, and sends a pressure preparation completion signal to the landscape control unit 20 when the pressure set value is reached in the sealed space.

[0055] The pressure is measured by a pressure measuring component and converted into a pressure signal. When the preset pressure signal is reached, such as 50N or 100N, a signal can be sent to the landscape control unit 20 to start spraying water. The pressure signal can also be set to any value between 1 and 200N.

[0056] In a further embodiment: receiving the pressure preparation completion signal from the pressure measuring components in the plurality of dam bodies 1 includes:

[0057] Based on the preset water spraying effect, calculate the required pressure in the sealed space of each dam body 1;

[0058] After each pressure measuring component measures the required pressure, it sends a pressure preparation completion signal to the landscape control unit 20.

[0059] The pressure in the sealed space of dam body 1 can be calculated based on a preset value, such as 50N. Since the volume of the sealed space is constant and the area of ​​force application is also constant, pressure = pressure intensity × area of ​​force application (F = pS). This allows for the rapid calculation of the pressure in each section of dam body 1.

[0060] Reference Figure 3 In another embodiment: the pressure measuring component includes an installation groove, which is opened on the side wall of the dam body 1. The installation groove is connected to the pressurization groove 10. A movable plate 21 is movably sealed in the installation groove. A pressure plate 23 is connected to the side wall of the movable plate 21 through a pressure spring 22. The pressure plate 23 is slidably connected to the inner wall of the installation groove. A pressure sensor 24 is provided on the bottom wall of the installation groove. The pressure sensor 24 is in contact with the pressure plate 23. An electronic air valve 25 is also provided on the sealing plate 14. The direction of the electronic air valve 25 is opposite to the direction of the first one-way valve 15.

[0061] When measuring pressure, the pressure in the sealed space will exert pressure on the pressure plate 23. The pressure will cause the pressure plate 23 to move and the pressure spring 22 to deform. The rebound force of the pressure spring 22 can exert a certain pressure on the pressure sensor 24. This will allow the pressure sensor 24 to generate a certain pressure. When the pressure in the sealed space is large and exceeds the upper limit of the preset value, the electronic air valve 25 can be opened to allow the gas in the sealed space to enter the pressurized space. Then the electronic air valve 25 can be closed to bring the pressure in the sealed space to a stable state.

[0062] In a further embodiment: a slidable extrusion block 26 is also connected above the pressure groove 10. The sidewall of the extrusion block 26 is connected to the sidewall of the dam body 1 through an elastic member 27. One end of the extrusion block 26 extends outside the plane of the sidewall of the pressure groove 10, and the extrusion block 26 is located on the moving trajectory of the impact plate 9.

[0063] The rebound force provided by the compression block 26 and the elastic element 27 ensures that after the impact plate 9 is impacted, it will not remain on the pressure groove 10 when it approaches the pressure groove 10. Instead, under the rebound force of the elastic element 27, the impact plate 9 will be pushed back to its original position.

[0064] In summary, compared with existing technologies, it has the following beneficial effects:

[0065] 1. By setting the impact plate 9 and the pressurization component, the impact of water flow can be reduced through air pressure buffering. Moreover, the air pressure buffering effect is ideal and still has a good buffering effect after a long period of use.

[0066] 2. By using air pressure to push the push block 6 and the sealing rod 7 to move, the water in the diversion chamber 3 is squeezed and the water is sprayed out from the nozzle 5 through the conduit 4, thus forming a fountain. The spray direction can be changed according to the angle of the dam 1, thereby creating a better landscape effect.

[0067] 3. By installing solenoid valve 8, the fountain can be more easily controlled by humans when it sprays, resulting in a better landscape effect. Moreover, the force of the fountain spray comes from the impact of water flow, which also has an energy-saving effect.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
