Description

Technical Field

[0001] This application relates to the technical field of water conservancy engineering, and in particular to a river sluice gate structure used in water conservancy construction. Background Technology

[0002] Water pollution mainly originates from pollutants generated during human societal development, including industry, agriculture, and daily life. To address water pollution, it is necessary to control pollution at its source and develop advanced cleanup technologies. River pollution primarily results from the long-term accumulation of pollutants in the sediment. Pollutants adsorbed on sediment particles exchange with pore water, releasing pollutants and causing secondary pollution of the water. Furthermore, the large amount of sediment provides a breeding ground for microorganisms, exacerbating river pollution. Therefore, regular cleaning of river sludge is crucial for controlling water pollution.

[0003] Existing river sluice gate structures used in water conservancy construction typically have sludge pumps installed at the gate opening to clean the sludge that has settled at the bottom of the river. However, the sludge pumps can only pump sludge from one fixed location, resulting in insufficient sludge removal. Installing multiple sludge pumps would inevitably increase the investment in equipment, so further improvements are needed. Summary of the Invention

[0004] To improve the sludge removal effect, this application provides a river sluice gate structure for water conservancy construction.

[0005] The technical solution for a river sluice gate structure used in water conservancy construction provided in this application is as follows: A river sluice gate structure for hydraulic construction includes a river body and a gate plate slidably installed on the river body. The gate plate is equipped with a lifting component for driving the gate plate to rise and fall to open and close the river body. The gate plate is provided with a collection box located at the front end of the gate plate in the direction of water flow to collect sludge. A push plate is slidably installed in the river body, located on the side of the collection box away from the gate plate. The surface of the push plate is normally in a horizontal state to allow water flow. The push plate is provided with a sliding component for driving the push plate closer to or away from the collection box. When the push plate moves towards the side closer to the collection box, the surface of the push plate rotates to a vertical state to push the sludge on the bottom wall of the river body.

[0006] By adopting the above technical solution, and through the setting of the push plate and collection box, the push plate is normally set horizontally, so that when the gate is open, the water flow can flow downstream through the push plate, and when the gate is closed, some of the sludge in the water flow can settle into the collection box. When cleaning the sludge on the bottom wall of the river body, the push plate is driven to move towards the side closer to the collection box by the sliding component. At this time, the push plate rotates to a vertical position to push the sludge settled on the bottom wall of the river body and push the sludge into the collection box. After a certain amount of sludge is collected in the collection box, the gate is driven to lift, so that the sludge collected in the collection box can be lifted away from the river body, so that the sludge in the collection box can be cleaned by the staff, improving the cleaning effect of sludge in the river body. At the same time, the gate is used to drive the collection box to rise and fall, eliminating the need for an additional drive source for the collection box and reducing the overall structural cost.

[0007] Optionally, the inner wall of the river channel body is provided with a first sliding groove, the two ends of the first sliding groove extend along the water flow direction and the two ends of the first sliding groove respectively form a first abutment surface and a second abutment surface, the first abutment surface is located on the side of the second abutment surface away from the gate plate; a sliding block is slidably installed in the first sliding groove, one side of the push plate is hinged to the sliding block, the push plate is slidably and rotatably installed in the river channel body through the sliding block; a reset member is provided between the sliding block and the push plate, the reset member normally rotates the plate surface of the push plate to a vertical state, and when the sliding block abuts against the first abutment surface, the plate surface of the push plate rotates to a horizontal state.

[0008] By adopting the above technical solution, through the setting of the sliding block and the first sliding groove, the sliding block causes the push plate to slide and rotate and be installed in the river body. When the push plate is not in use, it drives the sliding block to slide along the length direction of the first sliding groove and forces the sliding block to abut against the first contact surface. At this time, the surface of the push plate rotates to a horizontal state so that the water flow can pass over the push plate and flow to the gate, or the sludge in the water flow can pass over the push plate and collect in the collection box.

[0009] Optionally, the inner wall of the river channel body is fixed with a pushing block for abutting the push plate. When the sliding block abuts against the first abutting surface, the pushing block abuts against the push plate and rotates the surface of the push plate to a horizontal state. The surface of the push plate is kept in a horizontal state by the pushing block.

[0010] By adopting the above technical solution, and by setting the push block, the push plate rotates to a vertical state under the action of the reset member in normal condition to push the sludge of the river body. When the push plate is not in use, when the sliding block is forced to move towards the side closer to the first contact surface, the push plate can abut against the push block, so that the surface of the push plate can rotate to a horizontal state and be stored in the bottom wall of the river body.

[0011] Optionally, the inner wall of the river channel body is provided with a second sliding groove, the two ends of the second sliding groove are extended along the height direction of the gate, the lower end of the second sliding groove is connected to the first sliding groove and the inner wall of the second sliding groove is flush with the second abutment surface; the bottom wall of the river channel body is provided with an embedding groove for embedding the collection box, the top of the collection box is open, when the sliding block moves to abut against the second abutment surface, the push plate moves to the top of the collection box and the surface of the push plate near the gate is flush with the inner side wall of the collection box away from the gate.

[0012] By adopting the above technical solution, through the setting of the second sliding groove, the sludge on the bottom wall of the river body is pushed to the collection box by the pusher plate. When the sliding block slides along the length direction of the first sliding groove to abut against the second contact surface, the pusher plate moves above the collection box and lifts the gate, which can lift the collection box out of the water surface in the river body. During the lifting of the collection box, the sliding block enters the second sliding groove under the drive of the pusher plate and slides upward along the length direction of the second sliding groove, so that the pusher plate follows the lifting of the collection box. The pusher plate can increase the collection space of the collection box, reduce the possibility of excessive sludge overflowing the collection box, and thus improve the sludge cleaning effect.

[0013] Optionally, the top wall of the collection box is provided with an extension plate. Two extension plates are provided and symmetrically arranged on both sides of the top wall of the collection box. A plug-in rod is fixed on the side wall of the extension plate near the push plate. A plug-in groove is opened on the side wall of the push plate near the gate. When the sliding block moves to abut against the second contact surface, the plug-in rod is matched and plugged into the plug-in groove.

[0014] By adopting the above technical solution, and with the extension plate, when the push plate moves to abut against the extension plate, the extension plate and the push plate can jointly increase the collection space of the collection box to collect more sludge; when the push plate abuts against the extension plate, the plug rod is inserted into the plug groove, so that the extension plate and the push plate form a whole, and the surface of the push plate remains vertical, so that the collection box can drive the push plate to rise together.

[0015] Optionally, the sliding assembly includes a sliding bar and a sliding member. The sliding bar is slidably mounted in a first sliding groove and detachably connected to a sliding block. The sliding member is disposed on the sliding bar to drive the sliding bar closer to or further away from the collection box.

[0016] By adopting the above technical solution, through the setting of sliding bar and sliding member, the sliding member drives the sliding bar to slide along the length direction of the first sliding groove, and the sliding bar can drive the sliding block to slide along the length direction of the first sliding groove, so that the push plate can push the sludge attached to the bottom wall of the river body and push the sludge to the collection box.

[0017] Optionally, the sliding bar is located on the side of the sliding block away from the gate. A docking slider is fixed to the side wall of the sliding block near the sliding bar. A docking groove adapted to the shape of the docking slider is formed on the side wall of the sliding bar near the sliding block. The two ends of the docking groove extend along the height direction of the gate and pass through the two opposite side walls of the sliding bar. The docking slider is slidably installed in the docking groove. The sliding bar and the sliding block are detachably connected by the docking slider. When the sliding block slides along the second sliding groove, the docking slider disengages from the docking groove.

[0018] By adopting the above technical solution, through the setting of the docking slider and docking groove, when the sliding block moves to abut against the second contact surface, it drives the collection box to rise. The collection box drives the push plate to rise, causing the sliding block to enter the second sliding groove. At this time, the docking slider can disengage from the sliding bar along one end of the docking groove, thereby separating the sliding bar and the sliding block from each other, so that the sliding block can enter the second sliding groove. After the sludge in the collection box is cleaned, the gate is driven to descend, and the push plate follows the collection box to descend, so that the docking slider of the sliding block can re-enter the docking groove of the sliding bar, so that the sliding block and the sliding bar are reconnected. Then, the sliding bar is driven to move away from the gate, which can drive the push plate to move away from the gate to reset the push plate. This is repeated to periodically clean the sludge in the river body.

[0019] Optionally, the sliding bar abuts against the bottom wall of the riverbed body. When the push plate rotates to a vertical position, the sliding bar abuts against the side wall of the sliding block near the push plate. The sliding bar keeps the push plate vertical for pushing sludge.

[0020] By adopting the above technical solution, the surface of the pusher plate can always remain vertical as it moves towards the side closer to the gate, so as to push the sludge on the bottom wall of the river body to the collection box, reducing the possibility of the pusher plate rotating freely during the process of pushing the sludge due to excessive resistance of the sludge.

[0021] Optionally, the sliding block has a pushing surface on its sidewall away from the sliding bar, the pushing surface being used to push the sludge outward from the first sliding groove.

[0022] By adopting the above technical solution, and by setting the pushing surface, the sludge in the first sliding groove can be pushed outward by the pushing surface during the sliding block's movement along the first sliding groove, thereby reducing the possibility that the sliding block's movement will be obstructed due to excessive sludge in the first sliding groove.

[0023] Optionally, the push plate is connected to a spare pull rope for driving the plate surface to rotate to a vertical position. One end of the spare pull rope is connected to the side wall of the push plate, and the other end is used to connect to the top of the river body. When the sliding block slides along the first sliding groove or the second sliding groove, the spare pull rope is in an unstretched state.

[0024] By adopting the above technical solution and setting up a spare pull rope, which is not used under normal circumstances, if a heavy object such as a stone presses on the surface of the push plate and prevents the push plate from rotating to a vertical position, pulling the spare pull rope can force the push plate to flip over and rotate the push plate to a vertical position, so that the push plate can be used to push the sludge on the bottom wall of the river body, thereby improving the adaptability of the overall structure.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the design of the push plate and collection box, the push plate is normally horizontal, allowing water to flow downstream when the gate is open and some sludge in the water to settle into the collection box when the gate is closed. When cleaning the sludge on the bottom wall of the river, the push plate is moved towards the collection box via a sliding component. At this time, the push plate rotates to a vertical position to push the sludge settled on the bottom wall of the river into the collection box. After a certain amount of sludge is collected in the collection box, the gate is raised, which lifts the sludge collected in the collection box away from the river body, making it easier for workers to clean the sludge in the collection box and improving the cleaning effect of sludge in the river body. At the same time, the gate is used to drive the collection box to rise and fall, eliminating the need for an additional drive source for the collection box and reducing the overall structural cost. 2. By setting the push block, under normal conditions, the push plate rotates to a vertical state under the action of the reset member to push the sludge of the river body. When the push plate is not in use, when the sliding block is forced to move towards the side closer to the first contact surface, the push plate can abut against the push block, so that the plate surface of the push plate can rotate to a horizontal state to be stored in the bottom wall of the river body. 3. By setting up the docking slider and docking groove, when the sliding block moves to abut against the second contact surface, it drives the collection box to rise. The collection box drives the push plate to rise, allowing the sliding block to enter the second sliding groove. At this time, the docking slider can disengage from the sliding bar along one end of the docking groove, thereby separating the sliding bar and the sliding block from each other, so that the sliding block can enter the second sliding groove. After the sludge in the collection box is cleaned, the gate is driven to descend, and the push plate follows the collection box to descend, allowing the docking slider of the sliding block to re-enter the docking groove of the sliding bar, so that the sliding block and the sliding bar are reconnected. Then, the sliding bar is driven to move away from the gate, which can drive the push plate to move away from the gate to reset the push plate. This process is repeated to periodically clean the sludge in the river body. Attached Figure Description

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0029] This application discloses a river sluice gate structure for water conservancy construction.

[0030] Reference Figure 1 , Figure 2 A river sluice gate structure for water conservancy construction includes a river body 1 and a gate 2. The inner walls of the river body 1 on both sides are provided with lifting grooves 16. The two ends of the lifting grooves 16 extend along the height direction of the river body 1. The gate 2 is installed between the two lifting grooves 16 for opening and closing the river body 1. In this embodiment, the bottom wall of the river body 1 is provided with a sinkhole 17. The two ends of the sinkhole 17 extend along the width direction of the river body 1 and are respectively connected to the two lifting grooves 16. When the gate 2 is closed in the river body 1, the lower end of the gate 2 is embedded in the sinkhole 17.

[0031] Reference Figure 1 A mounting frame 18 is erected on the top of the river body 1. The mounting frame 18 is equipped with a lifting component. The lifting component is used to drive the gate plate 2 to rise and fall to open and close the river body 1. In this embodiment, the lifting component is set as a screw-type gate opener 19 (the screw-type gate opener 19 is a conventional technology in the field, and its structure will not be described in detail here). The screw-type gate opener 19 is connected to the gate plate 2 to drive the gate plate 2 to rise and fall.

[0032] Reference Figure 2 , Figure 3 , Figure 4 The bottom wall of the river body 1 is provided with an embedding groove 15, which is located at the front end of the gate 2 in the direction of water flow. A collection box 3 is installed on the side wall of the gate 2 near the embedding groove 15. The collection box 3 is used to collect sludge in the river body 1. In this embodiment, the collection box 3 is detachably installed on the gate 2 by bolt fixing. The top of the collection box 3 is open. When the gate 2 is closed to the river body 1, the collection box 3 is embedded in the embedding groove 15, and the top wall of the collection box 3 is flush with the bottom wall of the river body 1. The inner bottom wall of the collection box 3 is provided with multiple water permeable holes 31. All water permeable holes 31 are evenly distributed along the inner bottom wall of the collection box 3. Each water permeable hole 31 is a through hole that penetrates the bottom wall of the collection box 3. With this design, the sludge in the water flow will settle under the interception of the gate 2 and be collected in the collection box 3. This will drive the gate 2 to rise and bring out the collection box 3, so as to clean the sludge in the collection box 3.

[0033] Reference Figure 5 , Figure 6 The inner walls of the river body 1 on both sides are provided with first sliding grooves 11. The first sliding grooves 11 are located on the side of the collection box 3 away from the gate 2. The two ends of the first sliding grooves 11 extend along the length of the river body 1 (i.e., extend along the direction of water flow). A sliding block 12 is slidably installed in each first sliding groove 11. A push plate 4 is installed between two sliding blocks 12. One side of the push plate 4 is hinged to the sliding block 12. The push plate 4 is slidably and rotatably installed in the river body 1 through the sliding block 12. The sliding block 12 has a pushing surface 122 on the side wall near the collection box 3. When the sliding block 12 moves toward the side near the collection box 3, the sliding block 12 pushes the sludge in the first sliding groove 11 outward through the pushing surface 122.

[0034] A reset component is installed between the sliding block 12 and the push plate 4. The reset component normally rotates the surface of the push plate 4 to a vertical position to push the sludge on the bottom wall of the river body 1 and push the sludge into the collection box 3. In this embodiment, the reset component is set as a torsion spring (not shown in the figure). One end of the torsion spring is fixedly connected to the sliding block 12, and the other end is fixedly connected to the push plate 4. The torsion spring normally rotates the surface of the push plate 4 to a vertical position.

[0035] Reference Figure 1 , Figure 2 , Figure 6 The push plate 4 is equipped with a sliding component 5 for driving the push plate 4 closer to or away from the collection box 3. In this embodiment, the sliding component 5 includes a sliding strip 51 and a sliding member 52. The sliding strip 51 is long and the two ends of the sliding strip 51 are respectively slidably installed in two first sliding grooves 11. The sliding strip 51 is located on the side of the sliding block 12 away from the collection box 3. A docking slider 121 is fixedly installed on the side wall of the sliding block 12 near the sliding strip 51. The docking slider 121 is a T-shaped block. A docking groove 511 is opened on the side wall of the sliding strip 51 near the sliding block 12. The shape of the docking groove 511 is adapted to the shape of the docking slider 121. The two ends of the docking groove 511 extend along the height direction of the gate plate 2 and penetrate through the two opposite side walls of the sliding strip 51. The docking slider 121 is slidably installed in the docking groove 511. The sliding strip 51 and the sliding block 12 are detachably connected through the docking slider 121.

[0036] Reference Figure 5 , Figure 7 A sliding member 52 is disposed on a sliding strip 51 to drive the sliding strip 51 closer to or away from the collection box 3. In this embodiment, the sliding member 52 includes a lead screw 521, a transmission rod 522, and a drive motor 523. The lead screw 521 is rotatably installed in the first sliding groove 11, and both ends of the lead screw 521 extend along the length direction of the first sliding groove 11. The lead screw 521 passes through the sliding strip 51 and is threadedly connected to the sliding strip 51. The drive motor 523 is a servo motor, which is fixedly installed on the top of the river body 1. The transmission rod 522 is vertically arranged. The transmission rod 522 is coaxially fixed at one end to the output shaft of the drive motor 523, and the other end extends downward. A first bevel gear 524 is coaxially fixed to the outer peripheral wall of the end of the transmission rod 522 away from the drive motor 523, and a second bevel gear 525 is coaxially fixed to the outer peripheral wall of the lead screw 521. The first bevel gear 524 and the second bevel gear 525 mesh and transmit power. By driving the transmission rod 522 to rotate through the drive motor 523, the sliding bar 51 can be forced to slide along the length direction of the first sliding groove 11, thereby allowing the push plate 4 to move closer to or away from the collection box 3.

[0037] Reference Figure 2 , Figure 3 In this embodiment, the sliding bar 51 abuts against the bottom wall of the river body 1. When the push plate 4 rotates to a vertical state, the sliding bar 51 abuts against the side wall of the sliding block 12 of the push plate 4 away from the collection box 3. The sliding bar 51 keeps the push plate 4 in a vertical state to push the sludge.

[0038] Reference Figure 2 , Figure 3 , Figure 5For ease of description, the inner wall of the first sliding groove 11 away from the collection box 3 is defined as the first abutment surface 111, and the inner wall of the first sliding groove 11 near the collection box 3 is defined as the second abutment surface 112. Pushing blocks 13 are fixedly installed on both opposite inner walls of the river body 1. The pushing blocks 13 are located above the first sliding groove 11 and close to the first abutment surface 111 of the first sliding groove 11. The pushing blocks 13 are used for the push plate 4 to abut against, so as to rotate the surface of the push plate 4 to a horizontal state. When the sliding bar 51 moves towards the first abutment surface... When one side of the push plate 111 moves and abuts against the first abutting surface 111 (i.e., the sliding block 12 abuts against the first abutting surface 111 through the sliding strip 51), the surface of the push plate 4 rotates to a horizontal state under the action of the pushing block 13. The surface of the push plate 4 is kept in a horizontal state by the pushing block 13 for water flow. When the push plate 4 moves towards the side closer to the second abutting surface 112 and the pushing block 13 moves out of the top of the push plate 4, the surface of the push plate 4 rotates to a vertical state under the action of the torsion spring for pushing the sludge on the bottom wall of the river body 1.

[0039] Reference Figure 2 , Figure 3 , Figure 4 The inner walls of the river body 1 on both sides are provided with second sliding grooves 14. The two ends of the second sliding grooves 14 extend along the height direction of the gate plate 2. The upper end of the second sliding groove 14 penetrates the top wall of the river body 1. The lower end of the second sliding groove 14 is connected to the first sliding groove 11 and the inner wall of the second sliding groove 14 is flush with the second abutment surface 112. When the sliding block 12 moves to abut against the second abutment surface 112, the push plate 4 moves to the top of the collection box 3 and the plate surface of the push plate 4 near the gate plate 2 is flush with the inner wall of the collection box 3 away from the gate plate 2. The sliding block 12 can enter the second sliding groove 14 so that the push plate 4 rises with the gate plate 2. When the sliding block 12 slides upward along the length direction of the second sliding groove 14, the docking slider 121 of the sliding block 12 disengages from the docking groove 511 of the sliding strip 51.

[0040] Reference Figure 3 , Figure 4 , Figure 5 An extension plate 6 is fixedly installed on the top wall of the collection box 3. In this embodiment, there are two extension plates 6, which are symmetrically arranged on both sides of the top wall of the collection box 3. Multiple plug-in rods 61 are fixedly installed on the side wall of the extension plate 6 near the push plate 4. All plug-in rods 61 are arranged at intervals along the height direction of the extension plate 6. The side wall of the push plate 4 near the gate plate 2 is provided with a plug-in groove 41. There are multiple plug-in grooves 41, which are arranged one-to-one with all plug-in rods 61. When the sliding block 12 moves to abut against the second abutment surface 112, the plug-in rod 61 is matched and plugged into the plug-in groove 41.

[0041] Reference Figure 1 , Figure 2In this embodiment, the push plate 4 is connected to a spare pull rope 7. The spare pull rope 7 is used to pull the push plate 4 to force the plate surface of the push plate 4 to rotate to a vertical state. One end of the spare pull rope 7 is fixedly connected to the side wall of the push plate 4, and the other end is fixedly connected to the top of the river body 1. It should be noted that when the sliding block 12 slides along the first sliding groove 11 or the second sliding groove 14, the spare pull rope 7 is in an unstretched state.

[0042] The implementation principle of a river sluice gate structure for water conservancy construction according to an embodiment of this application is as follows: Under normal conditions, the sliding bar 51 moves to abut against the first contact surface 111. At this time, the push plate 4 is in a horizontal state under the action of the push block 13, so that water can flow through or the sludge in the water can pass through the push plate 4 and be collected in the collection box 3. When it is necessary to clean the sludge on the bottom wall of the river, the sliding bar 51 is driven to move towards the side closer to the second contact surface 112. During the movement of the sliding bar 51, the push plate 4 is released from the limiting effect of the push block 13, and the plate surface of the push plate 4 rotates to a vertical state under the action of the torsion spring. As the sliding bar 51 continues to move towards the side closer to the second contact surface 112, the push plate 4 and the sliding bar 51 can push the sludge settled on the bottom wall of the river body 1 to the collection box 3. By raising the gate plate 2, the collection box 3 can be lifted to facilitate the cleaning of the sludge in the collection box 3, which greatly improves the cleaning effect of the sludge in the river body 1.

[0043] When the sliding block 12 moves to abut against the second contact surface 112 under the push of the sliding bar 51, the insertion rod 61 of the extension plate 6 is inserted into the insertion slot 41 of the push plate 4, raising the collection box 3 and forcing the sliding block 12 to move into the second sliding groove 14, so that the push plate 4 can follow the collection box 3 to rise. The setting of the extension plate 6 and the push plate 4 expands the collection space of the collection box 3, reduces the possibility of the collection box 3 overflowing due to excessive sludge, and thus improves the sludge cleaning effect.

[0044] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
