Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a water conservancy engineering gate with automatic flow diversion and pressure relief function. Background Technology

[0002] Gates are control facilities used to close and open water discharge channels. They are an important part of hydraulic structures and can be used to intercept water flow, control water level, regulate flow, and discharge silt and floating debris.

[0003] In the prior art, such as the Chinese patent number "A hydraulic engineering gate with automatic flow diversion and pressure relief function", a gate pier is included. The gate pier is slidably connected to the inner side of the gate pier. An outer frame is fixedly installed on the front end face of the gate pier. A mixing mechanism is embedded in the inner side of the outer frame.

[0004] However, in the existing technology, most gates adopt a vertical structure. This structure lacks an effective guiding structure, and the intercepted water flow is always on one side of the gate. Therefore, during the release of water, the water will flow directly out from the opening. In this process, ordinary gates are not convenient to control the direction of the water flow, and it is easy for the water flow to spread rapidly or for the water flow to always flow in one direction. These situations will put great pressure on the nearby dams and the gate itself. Summary of the Invention

One end of the curved connecting rod is rotatably connected to the inside of the arc-shaped protrusion. An extension block is fixedly installed on the top of the other side of the first and second guide plates. A limit rod is fixedly installed on the upper surface of the extension block. The limit rod is slidably connected to the inside of the blocking assembly. The length of the limit rod is greater than the thickness of the curved connecting rod.

[0009] Preferably, the blocking assembly includes a support frame and a gate body, the gate body being slidably mounted on one side of the support frame, and the gate body being located on one side of the first guide plate and the second guide plate.

[0011] Preferably, an arc-shaped adapter block is fixedly installed at one end of the electric cylinder, and the arc-shaped adapter block is sleeved on the outer wall of the positioning rod.

[0012] Preferably, a limiting groove is formed on the lower surface of the closed support plate, the top of the limiting rod is slidably connected to the groove wall of the limiting groove, and a limiting plate is fixedly installed on the inner wall of the support frame.

[0013] Preferably, a sealing sub-plate is fixedly installed at the junction of the second guide plate and the first guide plate. The sealing sub-plate is located on one side of the second guide plate, and a reinforcing rod is fixedly installed on one side of the sealing sub-plate. The reinforcing rod is fixedly installed at the junction of the second guide plate and the sealing sub-plate.

[0014] Preferably, a fixing plate is fixedly installed on one side of the second guide plate, a connecting support rod is fixedly installed on one end of the fixing plate, and a docking plate is rotatably connected to the other end of the connecting support rod.

[0015] Preferably, a docking cylinder is fixedly installed on one side of the second guide plate, the docking cylinder penetrates the limiting plate, and one end of the docking cylinder overlaps the inner wall of the support frame.

[0016] Preferably, one end of the docking plate overlaps the outer wall of the docking cylinder, and a limiting rod is fixedly installed at one end of the docking plate. One end of the limiting rod passes through the docking cylinder and overlaps the corner of the limiting plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, a separate flow guiding component is set on one side of the blocking component. This flow guiding component is located on one side of the gate body and does not affect the normal operation of the blocking component. After the blocking component opens the gate body, the angle of the first and second flow guiding plates can be changed by an electric cylinder. By using the cooperation of the first and second flow guiding plates, plus the combination of the flow guiding protrusions, the direction of water flow near the gate body can be changed, thereby achieving the purpose of flow guiding and solving the problems of rapid water diffusion and water flow always flowing in one direction. This reduces the pressure on the gate body and the nearby dam. At the same time, an additional sealing sub-plate is installed at the edge of the second flow guiding plate. The sealing sub-plate can not only help improve the stability when the first and second flow guiding plates are spliced ​​together, but also play a role in reinforcing the second flow guiding plate during the subsequent flow guiding process. The presence of the reinforcing rod can not only greatly improve the structural strength of the sealing sub-plate and the second flow guiding plate themselves, but also guide the flow direction of water between the first and second flow guiding plates and the support frame.

[0020] 2. In this invention, under normal circumstances, the limiting rod of the docking plate passes through the docking cylinder. At this time, the limiting plate will prevent the second guide plate from rotating clockwise, and the docking plate will restrict the second guide plate from rotating counterclockwise, so as to ensure the stability of the first guide plate and the second guide plate. When the electric cylinder operates, the angle of the first guide plate and the second guide plate will be changed by the curved rod on the positioning rotating rod, and then the docking plate will be pulled out from the docking cylinder by the fixing plate and the connecting support rod, thereby releasing the second guide plate and the first guide plate.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0032] Example 1

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9As shown: A hydraulic engineering gate with automatic flow diversion and pressure relief function includes a blocking component 1 and a flow diversion component 2. The flow diversion component 2 is movably installed on one side of the blocking component 1. The flow diversion component 2 includes a first flow diversion plate 21, a second flow diversion plate 22, and a positioning rotating rod 210. Flow diversion protrusions 29 are fixedly installed on the outer walls of both the first flow diversion plate 21 and the second flow diversion plate 22. The first flow diversion plate 21 and the second flow diversion plate 22 are spliced ​​together. An electric cylinder 24 is movably installed on the top of the blocking component 1. The wiring terminal of the electric cylinder 24 is connected to the control system of the blocking component 1. The two positioning rotating rods 210 are located on the oblique sides of the first flow diversion plate 21 and the second flow diversion plate 22, respectively. One end of the piston rod of the electric cylinder 24 is connected to an adapter end 26. The top of the positioning rotating rod 210 is fixedly installed... The assembly is equipped with a connecting end 27, and one side of the adapter end 26 is rotatably connected to the bottom of the connecting end 27. A curved connecting rod 214 is fixedly installed on the outer wall of the positioning rotating rod 210. An arc-shaped protrusion 213 is fixedly installed on the top of one side of the first guide plate 21 and the second guide plate 22. The arc-shaped protrusion 213 is located on the axis of the first guide plate 21 and the second guide plate 22. One end of the curved connecting rod 214 is rotatably connected to the inside of the arc-shaped protrusion 213. An extension block 211 is fixedly installed on the top of the other side of the first guide plate 21 and the second guide plate 22. A limit rod 212 is fixedly installed on the upper surface of the extension block 211. The limit rod 212 is slidably connected to the inside of the blocking assembly 1. The length of the limit rod 212 is greater than the thickness of the curved connecting rod 214.

[0034] In this embodiment, the flow guiding component 2 is disposed on one side of the blocking component 1. The state of the flow guiding component 2 is controlled by the electric cylinder 24 disposed on the top of the blocking component 1. The wiring terminal of the electric cylinder 24 is connected to the control system of the blocking component 1. When water is released, the blocking component 1 is opened first to release the water flow, and the flow guiding component 2 is started simultaneously.

[0035] The flow guiding assembly 2 is mainly composed of a first flow guiding plate 21 and a second flow guiding plate 22. The first flow guiding plate 21 and the second flow guiding plate 22 have the same structure and shape. Usually, the first flow guiding plate 21 and the second flow guiding plate 22 are in a spliced ​​state. In this state, the piston rod of the electric cylinder 24 is in a fully extended state. When guiding the flow, the electric cylinder 24 retracts the piston rod and pulls the connecting end 27 through the adapter end 26, thereby driving the positioning rotating rod 210 to rotate. The bottom of the positioning rotating rod 210 is rotatably connected to the ground. During the rotation of the positioning rotating rod 210, it will synchronously drive the curved connecting rod 214. The curved connecting rod 214 is connected to the arc-shaped protrusion 213 on the top of the first flow guiding plate 21 and the second flow guiding plate 22. The arc-shaped protrusion 213 is located on the axis of the flow guiding plate. Therefore, the rotation of the curved connecting rod 214 will pull the first flow guiding plate 21 and the second flow guiding plate 22.

[0036] During the process of the first guide plate 21 and the second guide plate 22 being pulled, since the limiting rod 212 on the extension block 211 is connected to the blocking component 1, the first guide plate 21 and the second guide plate 22 will rotate around the rotating limiting rod 212 while being pulled, thereby changing their own angle. After the angle is changed, the first guide plate 21 and the second guide plate 22 can block the water flow and play the role of guiding the flow.

[0037] The height of the limiting rod 212 is greater than the thickness of the curved connecting rod 214, so it will not affect the normal rotation of the second guide plate 22.

[0038] Example 2

[0039] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the blocking assembly 1 includes a support frame 11 and a gate body 12. The gate body 12 is slidably mounted on one side of the support frame 11 and is located on one side of the first guide plate 21 and the second guide plate 22. A closed support plate 13 is fixedly mounted on the top of the support frame 11. An I-shaped positioning block 14 is fixedly mounted on the upper surface of the closed support plate 13. Positioning rods 15 are fixedly mounted on both sides of the I-shaped positioning block 14. A curved connecting rod 214 is located between the closed support plate 13 and the first guide plate 21 and the second guide plate 22. An arc-shaped transition block 219 is fixedly mounted on one end of the electric cylinder 24. The arc-shaped transition block 219 is sleeved on the outer wall of the positioning rod 15. A curved connecting rod 214 is fixedly mounted on the outer wall of the positioning rotating rod 210. The first guide plate... Arc-shaped protrusions 213 are fixedly installed on the top of one side of the first guide plate 21 and the second guide plate 22. The arc-shaped protrusions 213 are located on the axis of the first guide plate 21 and the second guide plate 22. One end of the curved connecting rod 214 is rotatably connected to the inside of the arc-shaped protrusions 213. Extension blocks 211 are fixedly installed on the top of the other side of the first guide plate 21 and the second guide plate 22. Limiting rods 212 are fixedly installed on the upper surface of the extension blocks 211. The limiting rods 212 are slidably connected to the inside of the blocking assembly 1. The length of the limiting rods 212 is greater than the thickness of the curved connecting rods 214. A limiting groove 16 is opened on the lower surface of the closed support plate 13. The top of the limiting rods 212 is slidably connected to the groove wall of the limiting groove 16. A limiting plate 17 is fixedly installed on the inner wall of the support frame 11.

[0040] In this embodiment, the blocking component 1 consists of a support frame 11 and a gate body 12. The gate body 12 moves up and down along the support frame 11 to achieve the purpose of closing and opening the water channel. After the support frame 11 moves up the gate body 12, the water flow can proceed.

[0041] The electric cylinder 24 is located on the closed support plate 13 at the top of the support frame 11, and is rotatably connected to the positioning rod 15 through the arc-shaped transition block 219. The positioning rod 15 is installed in the I-shaped positioning block 14 to determine the position of one end of the electric cylinder 24. The position of one end of the piston rod of the electric cylinder 24 is determined by the positioning rotating rod 210, thereby determining the position of the electric cylinder 24.

[0042] When the electric cylinder 24 retracts the piston rod, the positioning rotating rod 210 is driven to rotate through the adapter end 26 and the connecting end 27. The presence of the adapter end 26 and the arc-shaped adapter block 219 provides sufficient space for the rotation of the electric cylinder 24. The curved connecting rod 214 is located between the closed support plate 13 and the first guide plate 21 and the second guide plate 22, so it will not affect the normal rotation of the first guide plate 21 and the second guide plate 22.

[0043] The positioning rod 210 drives the first guide plate 21 and the second guide plate 22 to rotate through the curved connecting rod 214. During this process, the limiting rod 212 will always move along the direction of the limiting slide groove 16 to ensure the stability of the first guide plate 21 and the second guide plate 22 when they move.

[0044] Example 3

[0045] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the flow guiding assembly 2 includes a first flow guiding plate 21, a second flow guiding plate 22, and positioning rotating rods 210. Flow guiding protrusions 29 are fixedly installed on the outer walls of both the first and second flow guiding plates 21 and 22. The first flow guiding plate 21 and the second flow guiding plate 22 are spliced ​​together. An electric cylinder 24 is movably installed on the top of the blocking assembly 1. The wiring terminal of the electric cylinder 24 is connected to the control system of the blocking assembly 1. The two positioning rotating rods 210 are located on the oblique sides of the first flow guiding plate 21 and the second flow guiding plate 22, respectively. One end of the piston rod is connected to an adapter end 26. The top of the positioning rotating rod 210 is fixedly installed with a connecting end 27. One side of the adapter end 26 is rotatably connected to the bottom of the connecting end 27. A sealing sub-plate 23 is fixedly installed at the junction of the second guide plate 22 and the first guide plate 21. The sealing sub-plate 23 is located on one side of the second guide plate 22. A reinforcing rod 25 is fixedly installed on one side of the sealing sub-plate 23. The reinforcing rod 25 is fixedly installed at the junction of the second guide plate 22 and the sealing sub-plate 23.

[0046] In this embodiment, the first guide plate 21 and the second guide plate 22 guide the direction of the water flow through the guide protrusion 29. The presence of the guide protrusion 29 divides the first guide plate 21 and the second guide plate 22 into multiple regions. When the water flow comes into contact with the first guide plate 21 and the second guide plate 22, the upward movement space and the downward movement space are restricted by the guide protrusion 29, thereby improving the guiding quality and speed.

[0047] The closed sub-plate 23 set at the edge of the second guide plate 22 is used to absorb the impact force of the water flow. At the same time, when the first guide plate 21 and the second guide plate 22 are joined together, it helps to improve the stability of the first guide plate 21 and the second guide plate 22 when they are joined together. When the water flow passes through the edge of the second guide plate 22, the high-speed impact force will be transmitted to the closed sub-plate 23. These impact forces are then transmitted to the second guide plate 22 through the reinforcing rod 25. At this time, the second guide plate 22 is still bearing the impact of the water flow. Therefore, the forces transmitted to the second guide plate 22 will cancel each other out, thereby improving the stability of the second guide plate 22.

[0048] Example 4

[0049] according to Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, a limiting plate 17 is fixedly installed on the inner wall of the support frame 11. A fixing plate 28 is fixedly installed on one side of the second guide plate 22. A connecting support rod 215 is fixedly installed on one end of the fixing plate 28. A docking plate 216 is rotatably connected to the other end of the connecting support rod 215. A docking cylinder 217 is fixedly installed on one side of the second guide plate 22. The docking cylinder 217 passes through the limiting plate 17. One end of the docking cylinder 217 overlaps the inner wall of the support frame 11. One end of the docking plate 216 overlaps the outer wall of the docking cylinder 217. A limiting insertion rod 218 is fixedly installed on one end of the docking plate 216. One end of the limiting insertion rod 218 passes through the docking cylinder 217 and overlaps at the corner of the limiting plate 17. A through hole 18 is provided at the junction of the limiting plate 17 and the docking cylinder 217. The diameter of the through hole 18 is larger than the diameter of the docking cylinder 217.

[0050] In this embodiment, when the first guide plate 21 and the second guide plate 22 are spliced ​​together, the docking cylinder 217 rests on the support frame 11, and the limiting rod 218 also passes through the docking cylinder 217 and rests on the limiting plate 17, so as to reinforce the first guide plate 21 and the second guide plate 22.

[0051] The electric cylinder 24 drives the first guide plate 21 and the second guide plate 22 to rotate via the positioning rod 210. During the rotation of the first guide plate 21 and the second guide plate 22, the side fixing plate 28 will be driven synchronously. The fixing plate 28 is connected to the docking plate 216 via the connecting support rod 215. However, since the connecting support rod 215 and the fixing plate 28 are in a fixed state, and the docking plate 216 and the connecting support rod 215 are in a rotatable connection state, when the first guide plate 21 and the second guide plate 22 rotate, the limiting rod 218 will be taken away from the docking cylinder 217 to ensure that the second guide plate 22 can rotate. The through hole 18 located in the limiting plate 17 can ensure that the docking cylinder 217 can move normally when the first guide plate 21 and the second guide plate 22 rotate.

[0052] The usage and working principle of this device: The flow guiding component 2 is located on one side of the blocking component 1. The flow guiding component mainly consists of the first flow guiding plate 21 and the second flow guiding plate 22. Its power source is provided by the electric cylinder 24 located on the closed support plate 13. In the normal state, the gate body 12 is at the lowest point, and the first flow guiding plate 21 and the second flow guiding plate 22 are also spliced ​​together. At this time, the closed sub-plate 23 is located at the junction of the first flow guiding plate 21 and the second flow guiding plate 22, which improves the stability of the first flow guiding plate 21 and the second flow guiding plate 22. One end of the docking cylinder 217 is pressed against the inner wall of the support frame 11. The limiting rod 218 passes through the docking cylinder 217 and is pressed against the corner of the limiting plate 17, which also helps to limit the position of the first flow guiding plate 21 and the second flow guiding plate 22. The water channel is in a closed state. When waterproofing is required, the gate body 12 moves upward, and the electric cylinder 24 changes the angle of the first flow guiding plate 21 and the second flow guiding plate 22, thereby opening the water channel and completing the waterproofing.

[0053] The electric cylinder 24 retracts the piston rod to drive the adapter end 26. The adapter end 26 pulls the positioning rotating rod 210 to rotate through the connecting end 27, thereby changing the state of the curved connecting rod 214. The curved connecting rod 214 drives the first guide plate 21 and the second guide plate 22 through the arc-shaped protrusion 213. Since the arc-shaped protrusion 213 is on the axis, and the first guide plate 21 and the second guide plate 22 are also connected to the limiting groove 16 on the lower surface of the closed support plate 13 through the limiting rod 212 on the extension block 211, the first guide plate 21 and the second guide plate 22 will be pulled by the curved connecting rod 214 to reduce the rotation around the limiting rod 212, and finally achieve the purpose of changing their own angle.

[0054] During the rotation of the first guide plate 21 and the second guide plate 22, the limiting rod 218 will be carried away from the docking cylinder 217 by the fixing plate 28 and the connecting support rod 215. The presence of the through hole 18 will not affect the normal movement of the docking cylinder 217, thus avoiding affecting the normal rotation of the first guide plate 21 and the second guide plate 22. After rotation, the first guide plate 21 and the second guide plate 22 can restrict the direction of water flow. When the water flow comes into contact with the first guide plate 21 and the second guide plate 22, the upward and downward movement space will be restricted by the guide protrusion 29, further improving the quality and speed of the guide flow.

[0055] Furthermore, when the water flows, it will generate a certain impact force on the closed sub-plate 23. This impact force will be transmitted to the second guide plate 22 through the reinforcing rod 25. At this time, the second guide plate 22 is still under the impact of the water flow. Therefore, the forces transmitted to the second guide plate 22 will cancel each other out, thereby improving the stability of the second guide plate 22.

[0056] Among them, the electric cylinder 24 and the gate body 12 are both existing technologies, and their components and operating principles are publicly available technologies, so they will not be explained in detail here.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
