Technical Field
[0001] This utility model relates to the field of gate technology, and in particular to a preventive dredging device for lifting gates used in water conservancy projects. Background Technology
[0002] Lift gates in water conservancy projects are important hydraulic structures used to regulate water flow, control water level and volume, and fulfill various functions of the water conservancy project. To ensure the gate's sealing performance, a gate groove is usually opened on the bottom surface of the water flow hole in the gate body, allowing the gate body and the gate to fit together through the groove. However, when the gate is open and water flows through the water flow hole, sediment in the water can easily enter the gate groove. Because the groove structure cannot be carried away by subsequent water flow, sediment accumulates in the gate groove, causing it to fail and thus weakening the gate's sealing performance. Utility Model Content
[0003] The technical problem to be solved by this utility model is: in order to overcome the problem in the prior art that when the gate is opened and the water flows through the water flow hole, the mud and sand in the water easily enter the gate groove, and because the structure of the groove cannot be carried out by the subsequent water flow, the mud and sand accumulate in the gate groove, causing the gate groove to fail, that is, the gate's sealing performance is weakened, a preventive dredging device for lifting gates in water conservancy projects is provided.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a preventive dredging device for a lifting gate in water conservancy projects, comprising...
[0005] The gate body has a flow passage at its lower part and a receiving cavity at its upper part to accommodate the gate body. The receiving cavity is connected to the flow passage, and a door groove is formed on the bottom surface of the flow passage to accommodate the bottom end of the gate body.
[0006] The gate body can move and flow within the accommodating cavity and the flow passage and control the opening and closing of the flow passage. The gate body divides the flow passage into the inlet side and the outlet side.
[0007] The lifting drive unit is used to provide power for the movement of the gate. The lifting drive unit is fixedly connected to the gate body, and the output end of the lifting drive unit is fixedly connected to the gate body.
[0008] The dredging assembly includes two traction buckets, which are rotatably connected to the gate body. The traction bucket includes a main body and a transmission part, which are fixedly connected to the main body. The main body has an inwardly recessed traction chamber for traction of bottom sediment flow. The transmission part is located on the moving path of the gate body. Through the design of the two traction buckets, after the gate is opened, the flow hole and the gate slot will be blocked, so that the sediment in the water passes through the gate along the surface of the traction bucket and will not enter the gate slot, thus ensuring the sealing of the gate after it is closed.
[0009] When the gate is located inside the flow passage and the flow passage is closed, the traction chamber of the traction bucket fits against the gate.
[0010] When the gate is located in the accommodating cavity, the main body of the traction bucket and the gate body are in contact, and the transmission parts of the two traction buckets are in contact, blocking the flow hole and the gate slot.
[0011] To address the issue of silt and sand in water not easily passing through the traction bucket, the main body further includes a concave surface with a traction surface that slopes downwards towards the end of the flow passage on its side.
[0012] To address the problem of silt accumulation on the surface of the traction bucket, a dredging assembly is further included, comprising several cleaning wheels that are rotatably connected to the traction bucket. The cleaning wheels are used to remove silt from the traction surface of the traction bucket.
[0013] To address the issue of water flow disturbing the traction bucket and causing it to float up and down, a stabilizing block is further installed inside the inlet side of the flow passage. The stabilizing block is fixedly connected to the gate body and is located in front of the traction bucket inside the inlet side.
[0014] To address the issue of impurities accumulating on the gate surface, a sludge removal component is further included, comprising a scraper fixedly connected to the gate body, with the scraper positioned at the top of the flow passage.
[0015] The lifting drive component includes a rotating handle, a lead screw, and a connecting seat. The lead screw is rotatably connected to the gate body and extends into the receiving cavity. The connecting seat is located in the receiving cavity and is threadedly connected to the lead screw. The connecting seat is fixedly connected to the gate body, and the rotating handle is fixedly connected to the input end of the lead screw.
[0016] It further includes a connection between the two traction buckets via a traction rope, which is located between the traction bucket and the brake body.
[0017] The beneficial effects of this utility model are: The lifting gate preventive dredging device provided by this utility model, through the design of two traction buckets, will block the flow hole and gate slot after the gate is opened, so that the mud and sand in the water will pass through the gate along the surface of the traction buckets and will not enter the gate slot, thus ensuring the sealing of the gate after it is closed.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0029] like Figure 1 This is a schematic diagram of the structure of this utility model, a preventive dredging device for lifting gates used in water conservancy projects, including...
[0030] like Figure 2 As shown, the gate body 1 has a flow passage 11 at its lower part, and a receiving cavity 12 for accommodating the gate body 2 is provided in the upper part of the gate body 1. The receiving cavity 12 is connected to the flow passage 11, and a door groove 13 for accommodating the bottom end of the gate body 2 is provided on the bottom surface of the flow passage 11.
[0031] like Figure 2 As shown, the door body 2 can move and flow within the accommodating cavity 12 and the flow passage 11 and control the opening and closing of the flow passage 11. The door body 2 divides the flow passage 11 into an inlet side 14 and an outlet side 15.
[0032] like Figure 2As shown, the lifting drive 3 provides power for the movement of the gate 2. The lifting drive 3 is fixedly connected to the gate body 1, and the output end of the lifting drive 3 is fixedly connected to the gate body 2. The lifting drive 3 includes a rotating handle 31, a lead screw 32, and a connecting seat 33. The lead screw 32 is rotatably connected to the gate body 1 and extends into the receiving cavity 12. The connecting seat 33 is located in the receiving cavity 12 and is threadedly connected to the lead screw 32. The connecting seat 33 is fixedly connected to the gate body 2, and the rotating handle 31 is fixedly connected to the input end of the lead screw 32.
[0033] In another embodiment, the rotating handle 31 can be replaced by a motor, and the lifting drive 3 can also be a hydraulic cylinder. This application does not specifically limit the specific implementation of this feature.
[0034] like Figure 2 , 3 As shown in Figure 4, and the dredging component 4, which includes two traction buckets 41, the traction buckets 41 and the gate body 1 are rotatably connected, the traction buckets 41 include a main body 411 and a transmission part 412, the transmission part 412 and the main body 411 are fixedly connected, the main body 411 has an inwardly recessed traction cavity 4111 for traction of the bottom mud and sand flow, and the transmission part 412 is located on the moving path of the gate body 2.
[0035] When the door body 2 is located inside the flow passage 11 and closes the flow passage 11, the traction chamber 4111 of the traction bucket 41 fits against the door body 2.
[0036] When the gate body 2 is located in the accommodating cavity 12, the main body 411 of the traction bucket 41 contacts the gate body 1, and the transmission parts 412 of the two traction buckets 41 contact each other, blocking the passage hole 11 and the gate groove 13.
[0037] like Figure 2 , 3 As shown in Figure 4, the concave surface of the main body 411 has a traction surface 4112 that slopes downward toward the end of the flow hole 11 on its side. The traction surface 4112 can traction the flow of water, thereby causing the water flow to carry the mud and sand through the flow hole 11.
[0038] like Figure 2 , 3 As shown in Figure 4, the dredging component 4 includes several cleaning wheels 42, which are rotatably connected to the traction bucket 41. The cleaning wheels 42 are used to remove mud and sand from the traction surface 4112 of the traction bucket 41. Driven by the water flow, the cleaning wheels 42 rotate to clean the mud and sand on the surface of the traction bucket 41, preventing the mud and sand from remaining on the surface of the traction bucket.
[0039] like Figure 2 , 3As shown in Figure 4, a stabilizing block 16 is installed in the water inlet side 14 through the flow hole 11. The stabilizing block 16 is fixedly connected to the gate body 1, and the stabilizing block 16 is located in front of the traction bucket 41 in the water inlet side 14. The stabilizing block 16 guides the flow of water, so that the traction bucket 41 in the water inlet side 14 is stable. The presence of the stabilizing block 16 ensures that the main body of the water flows over the traction bucket 41 and does not enter the gap between the traction bucket 41 and the gate body 1.
[0040] like Figure 2 , 3 As shown in Figure 4, the sludge removal component 4 includes a scraper 43, which is fixedly connected to the gate body 1. The scraper 43 is located at the top of the flow passage 11. When the gate body 2 is raised and lowered, the scraper 43 scrapes away the impurities retained on its surface to ensure the cleanliness of the gate body 2.
[0041] like Figure 5 As shown, the two traction buckets 41 are connected by a traction rope 44. The traction rope 44 is located between the traction bucket 41 and the gate body 1. The traction rope 44 is used to maintain the basic orientation of the traction bucket 41 and prevent it from deflecting excessively toward the gate body 2, thereby hindering the closing of the gate body 2.
[0042] When the gate body 2 is in the flow passage 11 and the gate is in the closed state, the traction chamber 4111 of the traction bucket 41 faces the gate body 2 and contacts the gate body 2.
[0043] In use, when the gate 2 is raised and enters the receiving cavity 12, the weight of the main body 411 of the traction bucket 41 is greater than the weight of the transmission part 4112. When the gate 2 is initially opened, the water flows through the gap between the gate 2 and the gate body 1. The water flow causes the flow hole 11 on the side of the traction bucket 41 to deflect and be in a downward angle. Then, after the gate 2 is raised and passes the rotating connection of the traction bucket 41, a large amount of water flows from above and presses against the traction cavity 4111, which causes the traction bucket 41 to rotate. The main body 411 and the gate body 1 on the side of it come into contact, and the transmission parts 412 of the two traction buckets 41 come into contact, blocking the flow hole 11 and the gate groove 13.
[0044] The device of this application is used to clean impurities accumulated on the gate body 1 of the gate and to prevent the mud and sand flowing through the gate groove 13 from accumulating in the gate groove 13. The cleaning is performed every time the gate is opened or closed, thereby gradually accumulating.
[0045] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
