Description

Technical Field

[0001] This invention relates to the field of sluice gate technology, specifically to an adaptive sealing structure for sluice gates. Background Technology

[0002] Sluice gates are key components in sluice gate engineering used to control water flow, regulate water level, and impound or release water. Their design and operation directly affect the function, safety, and durability of the sluice gate.

[0003] Because the existing screw-type gate hoist controls the gate by lifting and lowering the screw to move the gate up and down along the gate frame to open or close the gate, the overall structure and function are relatively simple and there is no effective sealing structure. In irrigation, water supply or water storage projects, poor sealing will lead to unnecessary water loss and affect the efficiency of water resource utilization.

[0004] Furthermore, different river channels have different conditions. After long-term use under complex working conditions, a large amount of silt will accumulate at the bottom of the gate frame, along with debris such as stones and branches. If the debris cannot be cleaned up in a timely and effective manner, the gate will not be able to descend to the bottom effectively, resulting in poor sealing at the bottom.

[0005] Leaking water may carry silt or impurities, which can erode the gate foundation or gate slot over time, leading to structural loosening or damage. Furthermore, the gate's descent and impact with rocks can also reduce the equipment's lifespan, making later maintenance difficult and affecting its performance. Therefore, an adaptive sealing structure for the sluice gate is needed to solve these problems. Summary of the Invention

[0013] Preferably, a connector pipe is provided at the center of the bottom plate of the screen frame, the lower end of the connector pipe extends into the sludge collection frame, the U-shaped pipe is provided at the lower end of the vertical pipe, the horizontal pipe of the U-shaped pipe passes through the gate body, the two vertical side pipes of the U-shaped pipe are respectively located on both sides of the gate body and the lower end of each is provided with a snap connector, the snap connector is snapped with the upper end of the connector pipe, and the snap connector and the connector pipe can be separated.

[0014] Preferably, the screen frame is provided with sliders at both ends of the back side, and the gate frame is provided with sliding grooves on both sides of the front and back sides that cooperate with the sliders, and the screen frame and the gate frame are slidably connected.

[0015] Preferably, the drive lifting assembly includes a bidirectional motor, a drive shaft, a drive gear, a rack and pinion, and a vertical connecting bar. The bidirectional motor is disposed on the upper surface of the mounting plate away from the pump body. There are two drive shafts, and one end of each drive shaft is close to the other and connected to the two output ends of the bidirectional motor.

[0016] Preferably, the mounting top plate has protrusions at both ends near the bidirectional motor, the drive shaft is rotatably connected to the protrusions at the end away from the bidirectional motor, and drive gears are fixedly sleeved on the outer surface of the two drive shafts near the protrusions. There are two racks, and the lower ends of the two racks are connected to the screen frame near the bidirectional motor. The drive gears and racks mesh with each other.

[0017] Preferably, there are two vertical connecting strips, the lower ends of the two vertical connecting strips are connected to the screen frame on the side away from the bidirectional motor, and the rack and the upper ends of the vertical connecting strips are provided with top connecting strips. The rack and the vertical connecting strips are slidably connected to the mounting top plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The sluice gate has an adaptive sealing structure. With the addition of a sludge collection frame and a screen frame, water flows through the sluice gate and passes through the guardrail on the screen frame, which can effectively block large debris such as stones or branches. Meanwhile, mud, smaller stones and other debris can pass through the guardrail. Because the outer surface of the rubber pad is arc-shaped and both sides of the base are inclined downwards, small stones and other debris falling on the rubber pad will automatically slide into the screen frame, while mud will fall into the sludge collection frame through the screen holes.

[0020] When the gate body moves down to close, the lower end of the gate body contacts and squeezes the rubber pad through the slot. The rubber pad contracts, which can effectively buffer the force. The boss and the rubber pad are locked into the slot, which can effectively ensure the sealing of the lower end of the sluice gate.

[0021] 2. The sluice gate features an adaptive sealing structure equipped with a drive lifting assembly. As water flows through, once a certain amount of waste is screened on the screen frame, a bidirectional motor activates, effectively driving two drive shafts to rotate synchronously. These drive shafts, in turn, drive a drive gear to rotate synchronously. Since the drive gear meshes with a rack, the gear's rotation causes the rack to move upwards. This upward movement of the rack, along with the top connecting strip, causes the vertical connecting strip to move upwards synchronously. This, in turn, causes both screen frames to move upwards synchronously. This allows workers to remove and centrally process the waste from the screen frames, preventing waste accumulation near the gate frame and ensuring the gate's seal when closed.

[0022] 3. The sluice gate has an adaptive sealing structure. With the sludge cleaning component, when the gate body is closed for a period of time, a large amount of sludge will be collected in the sludge collection frame. The pump body works, and the connector pipe can extract the sludge from the sludge collection frame and transport it to the U-shaped pipe. Then the sludge is discharged to the outside through the vertical pipe and the connecting hose. By regularly cleaning the sludge inside the sludge collection frame, the accumulation of sludge near the gate frame can be effectively avoided, which would affect the sealing performance of the gate body after it is closed.

[0032] 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.

[0033] Please see Figure 1-8 The sluice gate adaptive sealing structure includes a gate frame 1 and a gate body 5. The inner wall of the gate frame 1 is provided with a track groove, and the gate body 5 is slidably set in the track groove. A base 2 is provided at the lower end of the gate frame 1. A boss 201 is provided at the center of the upper surface of the base 2. A rubber pad 4 is provided on the upper surface of the boss 201. A slot 501 is provided at the lower end of the gate body 5. A sludge collection frame 202 is provided on both sides of the base 2. A screen frame 8 is provided on the upper surface of both sludge collection frames 202.

[0034] A mounting plate 3 is provided on the upper end of the gate frame 1. A sludge cleaning component 9 is provided on the mounting plate 3 and the gate body 5. A drive lifting component 11 is provided on the upper end of the screen frame 8.

[0035] The mounting plate 3 has a strip-shaped opening at its center. A screw 6 is located at the center of the upper surface of the gate body 5. A hoist 7 is located at the center of the upper surface of the mounting plate 3. The upper end of the screw 6 passes through the hoist 7 and extends to the outside. When the hoist 7 operates, it can effectively drive the screw 6 to move vertically up and down. During the vertical movement of the screw 6, it can effectively drive the gate body 5 to move up and down synchronously, realizing the opening or closing of the gate body 5. When the gate body 5 moves down to close, the lower end of the gate body 5 contacts and squeezes the rubber pad 4 through the slot 501. The rubber pad 4 contracts, which can effectively buffer the force. The boss 201 and the rubber pad 4 are inserted into the slot 501, which effectively ensures the sealing of the lower end of the sluice gate.

[0036] The bottom plate of the screen frame 8 has several screen holes 801, and several strip-shaped support rods 802 are evenly spaced on the front of the screen frame 8. A guardrail 803 is provided on the side of the screen frame 8 near the strip-shaped support rods 802. When the gate body 5 is in the raised open state, the water flows through the gate and the guardrail 803 can effectively block large-volume debris such as stones or branches. However, mud, smaller stones and other debris can pass through the guardrail 803. Since the outer surface of the rubber pad 4 is arc-shaped and both sides of the base 2 are inclined downwards, small stones and other debris falling on the rubber pad 4 will automatically slide into the screen frame 8. The mud will fall into the sludge collection frame 202 through the screen holes 801. Thus, when the gate body 5 is closed, the protrusion 201 and the rubber pad 4 can be effectively locked into the slot 501 to ensure the sealing of the lower end.

[0037] The sludge cleaning component 9 includes a pump body 901, a connecting hose 902, a vertical pipe 903, and a U-shaped pipe 904. The pump body 901 is located on one side of the upper surface of the mounting plate 3. The upper end of the connecting hose 902 is connected to the inlet of the pump body 901, and the lower end of the connecting hose 902 is connected to the upper end of the vertical pipe 903. The vertical pipe 903 is located on one side of the gate body 5. A positioning block 10 is fixedly fitted on the outer surface of the vertical pipe 903. The vertical pipe 903 is connected to the gate body 5 through the positioning block 10. The connecting hose 902 enables an effective connection between the vertical pipe 903 and the pump body 901. The positioning block 10 effectively ensures the stability of the position of the vertical pipe 903.

[0038] The bottom plate of the screen frame 8 is equipped with a connector pipe 804, the lower end of which extends into the sludge collection frame 202. A U-shaped pipe 904 is located at the lower end of the vertical pipe 903. The horizontal pipe of the U-shaped pipe 904 passes through the gate body 5. The two vertical side pipes of the U-shaped pipe 904 are located on both sides of the gate body 5, and each has a snap-fit ​​connector 905 at its lower end. The snap-fit ​​connector 905 is snapped into the upper end of the connector pipe 804. The snap-fit ​​connector 905 and the connector pipe 804 can be separated. When the gate body 5 is closed, a large amount of sludge will be collected in the sludge collection frame 202 after a period of time. With the operation of the pump body 901, the connector pipe 804 can extract the sludge inside the sludge collection frame 202 and transport it to the U-shaped pipe 904. Then, the sludge passes through the vertical pipe 903 and the connecting hose 902 and is finally discharged to the outside. By regularly cleaning the sludge inside the sludge collection frame 202, the accumulation of sludge near the gate frame 1 can be effectively avoided.

[0039] The screen frame 8 has sliders at both ends on the back side, and the gate frame 1 has grooves 101 on both sides of the front and back sides that cooperate with the sliders. The screen frame 8 is slidably connected to the gate frame 1. The sliders can effectively cooperate with the grooves 101 to limit the movement of the screen frame 8 and ensure that the screen frame 8 moves in the vertical direction.

[0040] The drive lifting assembly 11 includes a bidirectional motor 1101, a drive shaft 1102, a drive gear 1103, a rack 1104, and a vertical connecting strip 1105. The bidirectional motor 1101 is located on the upper surface of the mounting plate 3 away from the pump body 901. Two drive shafts 1102 are provided, with one end of each drive shaft 1102 close to the other and connected to the two output ends of the bidirectional motor 1101. Both ends of the mounting plate 3 near the bidirectional motor 1101 are provided with protrusions 301. The ends of the drive shafts 1102 away from the bidirectional motor 1101 are rotatably connected to the protrusions 301. A drive gear 1103 is fixedly sleeved on the surface, and two racks 1104 are provided. The lower ends of the two racks 1104 are connected to the screen frame 8 near the bidirectional motor 1101. The drive gear 1103 and the racks 1104 mesh with each other. The protrusions 301 provided can effectively limit and support the end of the drive shaft 1102. When the bidirectional motor 1101 works, it can effectively drive the two drive shafts 1102 to rotate synchronously. In turn, the drive shafts 1102 will drive the drive gear 1103 to rotate synchronously. Since the drive gear 1103 and the racks 1104 mesh with each other, the rotation of the drive gear 1103 will drive the racks 1104 to move up and down.

[0041] There are two vertical connecting bars 1105. The lower ends of the two vertical connecting bars 1105 are connected to the screen frame 8 on the side away from the bidirectional motor 1101. The rack 1104 and the upper end of the vertical connecting bars 1105 are provided with a top connecting bar 1106. Both the rack 1104 and the vertical connecting bars 1105 are slidably connected to the mounting top plate 3. When the rack 1104 moves up and down, it will drive the vertical connecting bars 1105 to move up and down synchronously through the top connecting bar 1106. In turn, the synchronous up and down movement of the rack 1104 and the vertical connecting bars 1105 will drive the two screen frames 8 to move up and down synchronously, which is convenient for garbage retrieval.

[0042] Working principle: The hoist 7 can effectively drive the screw 6 to move vertically up and down. During the vertical movement of the screw 6, the gate body 5 can be moved up and down synchronously, so as to open or close the gate body 5.

[0043] A positioning block 10 is fixedly sleeved on the outer surface of the vertical pipe 903. The vertical pipe 903 is connected to the gate body 5 through the positioning block 10. The connection hose 902 can effectively connect the vertical pipe 903 and the pump body 901. The positioning block 10 can effectively ensure the stability of the position of the vertical pipe 903. When the gate body 5 moves upward and opens, the vertical pipe 903 and the U-shaped pipe 904 move upward synchronously, and the clamping connector 905 separates from the connector pipe 804.

[0044] Water flows through the sluice gate and passes through the guardrail 803, which can effectively block large-volume garbage such as stones or branches. However, mud, smaller stones and other garbage can pass through the guardrail 803. Since the outer surface of the rubber pad 4 is arc-shaped and both sides of the base 2 are inclined downwards, small stones and other garbage falling on the rubber pad 4 will automatically slide into the screen frame 8, while mud will fall into the sludge collection frame 202 through the screen hole 801.

[0045] As water flows continuously, when the amount of waste screened on the screen frame 8 reaches a certain level, the bidirectional motor 1101 works, which can effectively drive the two drive shafts 1102 to rotate synchronously. In turn, the drive shafts 1102 drive the drive gear 1103 to rotate synchronously. Since the drive gear 1103 meshes with the rack 1104, the rotation of the drive gear 1103 can drive the rack 1104 to move upward. When the rack 1104 moves upward, it will drive the vertical connecting bar 1105 to move upward synchronously through the top connecting bar 1106. In turn, the synchronous upward movement of the rack 1104 and the vertical connecting bar 1105 will drive the two screen frames 8 to move upward synchronously. Then, the staff can take out the waste on the screen frame 8 and process it centrally.

[0046] When the gate body 5 moves down to close, the lower end of the gate body 5 contacts and squeezes the rubber pad 4 through the groove 501. The rubber pad 4 contracts, which can effectively buffer the force. The boss 201 and the rubber pad 4 are inserted into the groove 501, which effectively ensures the sealing of the lower end of the sluice gate.

[0047] Furthermore, after the gate body 5 is closed for a period of time, a large amount of sludge will be collected in the sludge collection frame 202. With the operation of the pump body 901, the connector pipe 804 can extract the sludge inside the sludge collection frame 202 and transport it to the U-shaped pipe 904. Then, the sludge is discharged to the outside through the vertical pipe 903 and the connecting hose 902. By regularly cleaning the sludge inside the sludge collection frame 202, the accumulation of sludge near the gate frame 1 can be effectively avoided, which would affect the sealing performance of the gate body 5 after it is closed.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
