Description

Technical Field

[0001] This invention belongs to the field of air filtration technology, and in particular relates to a device for cleaning mud and sand from the groove inside a gate. Background Technology

[0002] A sluice gate, or simply a sluice gate, is a low-head hydraulic structure built on rivers and canals to control flow and regulate water levels. When closed, the gate can impound floodwaters, block tides, or raise upstream water levels to meet needs for irrigation, power generation, navigation, aquaculture, environmental protection, industry, and domestic water use. When open, the gate can release floodwaters, floodwater, wastewater, or polluted water, and can also supply water to downstream rivers or canals. In water conservancy projects, sluice gates are widely used as structures for impounding, releasing, or drawing water. When closed, they can impound floodwaters, block tides, store water, and raise upstream water levels to meet upstream water intake or navigation needs. When open, they can release floodwaters, drain floodwaters, flush sediment, draw water, or regulate flow according to downstream water needs. Sluice gates are widely used in water conservancy projects and are commonly built in rivers, canals, reservoirs, lakes, and coastal areas.

[0003] After the gate is lowered during the flood season, its inner groove will be filled with silt and sand, which will cause the gate's weight to increase sharply. At this time, if the gate is lifted, there is a risk of breaking the steel wire rope. Since the existing system cannot be automatically cleaned, it needs to be cleaned manually by the staff. This requires the staff to clean the silt and sand inside the gate's inner groove. However, during the flood season, the water level is high, and it is easy for the staff to have accidents when they go into the water to clean the silt and sand, which will threaten their personal safety. To solve the above problems, a silt and sand cleaning device for the inner groove of the gate is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a sluice gate inner groove silt cleaning device to solve the problem that after the sluice gate is lowered during the flood season, its inner groove will be filled with silt, which will cause the gate's weight to increase sharply. At this time, if the gate is lifted, there is a risk of breaking the steel wire rope. Since the existing devices cannot be automatically cleaned, manual cleaning by workers is required. This requires workers to clean the silt inside the sluice gate's inner groove. However, during the flood season, the water level is high, and workers going into the water to clean the silt is prone to accidents, which threatens the safety of the workers.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a device for cleaning silt from an embedded groove in a gate, comprising a gate frame and a gate. A dual-axis motor and two winding frames are mounted on the upper surface of the gate frame. A winding roller rotates within each winding frame. The output end of the dual-axis motor passes through the winding frame and is fixedly connected to the winding roller. A first sprocket is fixedly connected to one end of each winding roller. A mounting box is fixedly connected to the rear side of the gate frame. A partition is fixedly connected inside the mounting box. Lead screws are connected to both sides of the partition. Moving blocks are mounted on the circumferential sides of the lead screws. A limit block is fixedly connected to one surface of each moving block, and a push plate is fixedly connected to one surface of each limit block. A second sprocket is fixedly connected to one end of each lead screw. A chain connects the first and second sprockets. An embedded groove is formed at the bottom of the gate frame. When the gate descends, the lead screws rotate, and the two moving blocks drive the push plate to move to both sides, discharging the sand accumulated in the embedded groove.

[0007] Preferably, both ends of the embedded groove are provided with sand discharge ports, and a mounting frame is fixedly connected above the sand discharge ports. A rotating shaft is connected inside the mounting frame. A torsion spring and a connecting rod are provided on the circumferential side of the rotating shaft. The connecting rod is fixedly connected to the rotating shaft. A baffle is fixedly connected to one end of the connecting rod. A push rod is fixedly connected to one surface of the push plate. The torsion spring fixes the push plate to block the sand discharge ports.

[0008] Preferably, a plurality of guide rails are fixedly connected to the front surface of the door frame, and guide blocks are provided on the peripheral side of the guide rails. A filter frame is fixedly connected between two guide blocks, and a plurality of connecting brackets are fixedly connected between the filter frame and the gate. Mounting seats are fixedly connected to both sides of the inner wall of the door frame, and sliders are installed in the mounting seats. A cleaning brush is fixedly connected between two sliders. A plurality of fasteners are connected to the upper surface of the mounting seats. The filter frame is used to block large pieces of mud and sand, preventing them from entering the embedded groove and causing blockage. The cleaning brush scrapes and cleans the surface of the gate, reducing its weight.

[0009] Preferably, a plurality of limiting grooves are provided on one side of the inner wall of the embedded groove, and the limiting block slides in cooperation with the limiting groove.

[0010] Preferably, the lead screw is rotatably connected to the partition plate, and the moving block is threadedly engaged with the lead screw.

[0011] Preferably, the push plate scrapes against the inner groove, and both the first sprocket and the second sprocket mesh with the chain.

[0012] Preferably, the position of the push rod corresponds to the position of the baffle, and the rotating shaft is rotatably connected to the mounting bracket.

[0013] Preferably, the position of the baffle corresponds to the position of the sand discharge port.

[0014] Preferably, the guide block slides with the guide rail, and the cleaning brush scrapes against the gate.

[0015] Preferably, the slider and the mounting base are in sliding engagement, and the fixing member is in threaded engagement with the mounting base.

[0016] The present invention has the following beneficial effects:

[0017] 1. This invention features automatic sand discharge from the inner groove as the gate descends, ensuring the safety of the wire rope while eliminating the need for workers to go into the water for cleaning, thus improving worker safety. Specifically, it utilizes a chain, two lead screws, and a push plate. When the gate descends, the winding roller drives the first sprocket to rotate, which in turn drives the second sprocket via the chain. The second sprocket further drives the two lead screws to rotate. The two lead screws are connected to the moving blocks via threads, causing the two moving blocks to move in opposite directions. The two moving blocks then drive the push plate via a limit block. The push plate pushes the sand inside the inner groove to both sides and discharges it through the sand discharge port, thus preventing the wire rope from breaking due to a sudden increase in gate weight and eliminating the need for workers to go into the water for cleaning. It is highly practical.

[0018] 2. When the gate is in the lower position, the present invention can block the sand discharge port to prevent sand from entering the inner groove and causing the gate to become blocked. Specifically, this is achieved by setting a torsion spring and a baffle. The baffle blocks the sand discharge port to prevent external sand from entering the inner groove. The torsion of the torsion spring can ensure that the baffle is in close contact with the sand discharge port and will not hinder the opening of the baffle to discharge sand.

[0019] 3. This invention effectively blocks sand and reduces its entry into the inner groove. It also scrapes and cleans sand adhering to the gate surface. Specifically, it uses a filter frame and a cleaning brush. The filter frame moves up and down with the gate. When the gate is lowered to the bottom, the filter frame also moves down, blocking large pieces of mud and sand flowing at the bottom without obstructing water flow. When the gate rises, the filter frame rises with it for easy cleaning. As the gate moves up and down, the cleaning brush scrapes and cleans the gate surface, reducing the gate's weight, lessening the tension of the wire rope, and effectively extending the service life of the wire rope. Furthermore, the cleaning brush is removable for easy periodic replacement.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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] In the description of this invention, it should be understood that the terms "upper," "middle," "outer," "inner," etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0033] Example 1:

[0034] Please see Figures 1-8 As shown, the present invention is a mud and sand cleaning device for an embedded groove in a gate, including a gate frame 1 and a gate 2. A dual-axis motor 3 and two winding frames 4 are provided on the upper surface of the gate frame 1. The dual-axis motor 3 and the winding frames 4 are both fixed to the upper surface of the gate frame 1 by bolts. Bearing seats are provided on both sides of the inner wall of the winding frame 4. The winding roller 5 is fixedly connected to the bearing seats by bolts. The output end of the dual-axis motor 3 passes through the winding frame 4 and is fixedly connected to the winding roller 5 by bolts. The dual-axis motor 3 drives the two winding rollers 5 to rotate simultaneously, winding or lowering the wire rope at the same time. The wire rope further drives the gate 2 to lift or lower, thereby realizing the function of opening and closing the gate 2.

[0035] One end of the take-up roller 5 is fixedly connected to a first sprocket 6, which is fixedly connected to the take-up roller 5 via a shaft. A mounting box 13 is fixedly connected to the rear side of the door frame 1. The mounting box 13 is connected and fixed to the door frame 1 by bolts, and a rectangular sealing ring is provided between the mounting box 13 and the door frame 1. The mounting box 13 is used to hold two lead screws 22, ensuring the sealing of the lead screws 22 within the mounting box 13. A partition 21 is fixedly connected inside the mounting box 13, dividing the mounting box 13 into two spaces, each holding one lead screw 22. Lead screws 22 are connected to both sides of the partition 21. The rod 22 is rotatably connected to the partition plate 21 through the bearing seat. The moving block 23 is threadedly engaged with the lead rod 22. The moving block 23 is installed on the circumferential side of the lead rod 22. A limit block 18 is fixedly connected to one surface of the moving block 23. Several limit grooves 17 are opened on one side of the inner wall of the embedded groove 16. The limit block 18 is slidably engaged with the limit groove 17. The limit block 18 cooperates with the limit groove 17 to limit the moving block 23 and prevent the moving block 23 from rotating with the lead rod 22. A push plate 19 is fixedly connected to one surface of the limit block 18. The push plate 19 is fixedly connected to the limit block 18 by bolts.

[0036] One end of the lead screw 22 is fixedly connected to a second sprocket 7. The lead screw 22 is also fixedly connected to the second sprocket 7 via a shaft. A chain 8 is connected between the first sprocket 6 and the second sprocket 7. Both the first sprocket 6 and the second sprocket 7 are engaged with the chain 8, which can transmit the rotation of the take-up roller 5, and further drive the lead screw 22 to rotate. An embedded groove 16 is provided at the bottom of the gate frame 1. When the gate 2 descends, its bottom will be inserted into the embedded groove 16. The dual-shaft motor 3 drives the two take-up rollers 5 to rotate synchronously. The two take-up rollers 5 drive the two first sprockets 6 to rotate synchronously. The first sprocket 6 engages with the chain 8, causing the chain 8 to rotate. The chain 8 further engages with the second sprocket 7, driving the second sprocket 7 to rotate. The second sprocket 7 further drives the lead screw 22 to rotate. The two moving blocks 23 move in opposite directions at the same time. While moving, the moving blocks 23 further drive the push plate 19 to move to both sides through the limit block 18. The push plate 19 discharges the sand accumulated in the embedded groove 16.

[0037] Working principle:

[0038] The dual-shaft motor 3 drives two take-up rollers 5 to rotate synchronously, lowering the wire rope. The wire rope further drives the gate 2, causing it to lower and insert its bottom into the inner groove 16. During this process, the two take-up rollers 5 synchronously drive two first sprockets 6 to rotate. The first sprockets 6 mesh with the chain 8, causing the chain 8 to rotate. The chain 8 further meshes with the second sprocket 7, causing the second sprocket 7 to rotate. The second sprocket 7 further drives the lead screw 22 to rotate. When the lead screw 22 rotates, the moving block 23 moves in opposite directions through its threaded engagement with it. During the movement, the moving blocks 23 are limited by... Position block 18 drives push plate 19 to move. Since push plate 19 is installed in the inner groove 16, it can push the mud and sand in the inner groove 16 to both sides and discharge them through the sand discharge port. During this movement, when the gate 2 is fully lowered, the two push plates 19 move to the two ends of the inner groove 16 respectively, without affecting the bottom of the gate 2. Similarly, when the gate 2 is raised, the two push plates 19 will move towards each other to facilitate the cleaning of mud and sand when the gate 2 is lowered next. This process is repeated to effectively ensure that mud and sand will not accumulate and increase the weight of the gate 2, effectively protecting the safety of the wire rope and extending the service life of the wire rope to a certain extent.

[0039] Example 2:

[0040] Both ends of the embedded groove 16 are provided with sand discharge ports for discharging the mud and sand accumulated in the embedded groove 16. A mounting bracket 24 is fixedly connected directly above the sand discharge port. The mounting bracket 24 is fixedly installed on both sides of the door frame 1 by bolts. A rotating shaft 25 is connected inside the mounting bracket 24 and is rotatably connected to the mounting bracket 24. A torsion spring 26 and a connecting rod 27 are provided on the peripheral side of the rotating shaft 25. The function of the torsion spring 26 is to provide torque to the baffle 14 so that it is tightly attached to both sides of the door frame 1. It can be optimized that a sealing ring (not shown in the figure) can be glued to the peripheral side of the baffle 14. To ensure the sealing between the baffle 14 and the sand discharge port, and to prevent mud and sand from entering the inner groove 16 through the sand discharge port when the gate 2 is below, the connecting rod 27 is fixedly connected to the rotating shaft 25, and one end of the connecting rod 27 is fixedly connected to the baffle 14. The position of the baffle 14 corresponds to the position of the sand discharge port. The position of the push rod 20 corresponds to the position of the baffle 14, ensuring that the push rod 20 can push the baffle 14 open when it moves to the position of the baffle 14. The push rod 20 is fixedly connected to one surface of the push plate 19, and the torsion spring 26 fixes the push plate 19 to block the sand discharge port.

[0041] Working principle:

[0042] In its initial state, the torsion spring 26 provides torque to the baffle 14, blocking the sand discharge port and ensuring the seal between the baffle 14 and the sand discharge port. This prevents sand from entering the inner groove 16 through the sand discharge port when the gate 2 is below. When the push plate 19 pushes the sand to the position of the sand discharge port, the push rod 20 lifts the baffle 14, thereby discharging the sand from the sand discharge port. The tight fit between the push plate 19 and the inner groove 16 reduces the amount of sand entering the inner groove 16 during the opening of the baffle 14. At this time, the torsion spring 26 is pulled. When the push rod 20 moves into the inner groove 16, the torsion spring 26 resets, driving the rotating shaft 25 to reset. The rotating shaft 25 further drives the baffle 14 to reset through the connecting rod 27, so that the baffle 14 continues to block and seal the sand discharge port.

[0043] Example 3:

[0044] Several guide rails 9 are fixedly connected to the front surface of the gate frame 1. The guide rails 9 are fixedly connected to the gate frame 1 by bolts. Guide blocks 10 are provided on the periphery of the guide rails 9. The cross-section of the guide rails 9 is "I" shaped, which can effectively guide the guide blocks 10 while limiting them to prevent them from falling off. The guide blocks 10 are slidably engaged with the guide rails 9. A filter frame 11 is fixedly connected between two guide blocks 10. Several connecting brackets 12 are fixedly connected between the filter frame 11 and the gate 2. Mounting seats 28 are fixedly connected to both sides of the inner wall of the gate frame 1. A slider 29 is installed in the mounting seat 28. The slider 29 is slidably engaged with the mounting seat 28. A cleaning brush 15 is fixedly connected between two sliders 29. The connection between the slider 29 and the cleaning brush 15 is welded. One surface of the cleaning brush 15 is provided with several bristles. The bristles are positioned corresponding to the front surface of the gate 2. The cleaning brush 15 scrapes against the gate 2. During the up and down movement of the gate 2, it scrapes against the cleaning brush 15, thereby cleaning the mud and debris adhering to the surface of the gate 2. For cleaning, the upper surface of the mounting base 28 is connected to several fasteners 30. Tightening the fasteners 30 clockwise tightens them, causing their bottom ends to abut against the slider 29, thus fixing the slider 29 and, consequently, the cleaning brush 15. After a period of use, the cleaning brush 15 will wear out, requiring disassembly and replacement. This is done by turning the fasteners 30 counterclockwise, causing their bottom ends to move upwards and no longer contact the cleaning brush 15. 5. Withdraw the cleaning brush 15 outwards to remove the slider 29 from the mounting base 28. This completes the disassembly of the cleaning brush 15. Then, replace it with a new cleaning brush 15. The fixing part 30 is threadedly engaged with the mounting base 28. The filter frame 11 is used to block large pieces of mud and sand. The filter frame 11 has multiple filter holes, which can block large pieces of mud and sand without obstructing the flow of water and preventing them from entering the inner groove 16 and causing blockage. The cleaning brush 15 scrapes and cleans the surface of the gate 2 to reduce its weight.

[0045] Working principle:

[0046] During the up-and-down movement of the gate 2, the filter frame 11 is moved up and down via the connecting frame 12. When the gate 2 moves to the bottom, the filter frame 11 moves down with it to block the mud and sand, preventing a large amount of mud and sand from entering the inner groove 16. When the gate 2 is raised, the filter frame 11 is raised with it, making it easier for staff to clean the debris inside the filter frame 11. During the up-and-down movement of the gate 2, it will scrape against the cleaning brush 15, thereby cleaning the mud and sand and debris adhering to the surface of the gate 2. After a period of use, the cleaning brush 15 will wear out, which requires disassembly and replacement. The fixing part 30 needs to be turned counterclockwise so that the bottom end of the fixing part 30 moves upward and no longer abuts against the cleaning brush 15. The cleaning brush 15 is then pulled outward to remove the slider 29 from the mounting base 28, thus completing the disassembly of the cleaning brush 15. Then, a new cleaning brush 15 can be replaced.
