Abstract

The present invention relates to the field of water conservancy engineering, and in particular to a water conservancy gate with a cleaning function. The technical problem to be solved is that the current movement of the gate will carry the silt accumulated at the bottom into the guide rail, which will affect the normal operation of the gate and accelerate the wear of the gate. The current cleaning and flushing of the gate are not comprehensive enough, and the gate will be corroded by dirt for a long time. A water conservancy gate with a cleaning function includes a frame, a guide rail and an upper cover plate, etc.; a guide rail is respectively installed on two opposite sides of the frame, and the two guide rails are symmetrically arranged, and an upper cover plate is installed on the top of the frame. When the outer walls of the two telescopic frames are flush with the two outer walls of the gate plate, the deposited silt can be separated from the outer walls of the two telescopic frames. When the gate plate and the two telescopic frames move in the direction close to the upper cover plate, the silt carried on the gate plate and the two telescopic frames can be reduced, thereby effectively reducing the silt from entering the guide rail and reducing the wear and corrosion of the gate.

Description

Technical Field

[0001] The invention relates to the field of water conservancy projects, and in particular to a water conservancy gate with a cleaning function. Background Art

[0002] During the operation of the gate, due to the continuous accumulation of impurities in the water, a large amount of silt will accumulate at the bottom of the gate, and a thick layer of dirt will form on the gate, which will not only affect the normal operation of the gate, but also accelerate the wear and corrosion of the gate.

[0003] In order to prevent the silt at the bottom of the gate from entering the guide rail as the gate moves, tools are generally used to first move the thick silt at the bottom of the gate to initially separate the silt from the bottom of the gate and reduce the amount of silt carried by the gate when it moves. However, this operation is more cumbersome and the silt is not removed thoroughly enough, with some silt still sticking to the bottom of the gate. In order to reduce the wear between the guide rail and the gate, clean water is now used to flush the gap between the guide rail and the gate, but this flushing efficiency is low and it is not convenient for a more comprehensive cleaning of both sides of the gate. Summary of the invention

Two motors 71 are installed on the upper cover plate 4 by bolts, and two fixing frames 72 are installed in the frame 1. Two threaded rods 73 are rotatably provided between the upper cover plate 4 and the two fixing frames 72 through bearings. A driving nut 74 is threadedly connected to the two threaded rods 73 respectively, and a horizontal plate 75 is installed between the two driving nuts 74. The horizontal plate 75 is slidably connected to the two slide grooves 3. The horizontal plate 75 will slide up and down along the two slide grooves 3. A vertical plate 76 is installed at the bottom of the horizontal plate 75. The vertical plate 76 slides through the gate cover 6. A limit plate 77 is installed at the middle of the vertical plate 76 by bolts. The limit plate 77 is located in the gate plate 5 and below the gate cover 6.

[0035] The telescopic mechanism includes a roller 81, a telescopic frame 82 and an inclined slot frame 83. Four rollers 81 are installed at the lower part of the vertical plate 76. A telescopic frame 82 is slidably provided on two opposite side surfaces at the lower part of the gate plate 5. The telescopic frame 82 will slide horizontally along the gate plate 5. The sides of the two telescopic frames 82 that are close to each other are both open. An inclined slot frame 83 is respectively installed on two opposite inner side surfaces of the two telescopic frames 82. The four rollers 81 are slidably located in the four inclined slot frames 83.

[0036] It also includes a baffle 9, with a baffle 9 installed on both sides of the cross plate 75 respectively. The baffle 9 is located in the frame 1, and the two baffles 9 are used to block the two slide grooves 3 respectively. The width of the baffle 9 is greater than the width of the slide groove 3, and the two side surfaces of the baffle 9 that are close to each other are in contact with the two inner side surfaces of the frame 1 respectively.

[0037] First, the device is set at the gate. Initially, the gate plate 5 is in the lowered state, and the two telescopic frames 82 are in the extended state. The water body can be intercepted by the gate plate 5. As the water storage capacity continues to increase, more silt will be deposited on the sides of the two telescopic frames 82. When it is necessary to open the gate to release water, the operator starts the output shafts of the two motors 71 to rotate. The rotation of the output shafts of the two motors 71 drives the two threaded rods 73 to rotate. The rotation of the two threaded rods 73 drives the two drive nuts 74 to move toward the direction close to the upper cover plate 4. The two drive nuts 74 drive the horizontal plate 75, the vertical plate 76, the limit plate 77 and the four rollers 81 toward the direction close to the upper cover plate 4. The two sliding grooves 3 guide the cross plates 75, and the four rollers 81 slide from the bottom of the inclined slot frame 83 to the top of the inclined slot frame 83. Under the action of the inclined slot frame 83, the two telescopic frames 82 move towards each other. When the outer walls of the two telescopic frames 82 are flush with the two outer walls of the gate plate 5, the limit plate 77 just touches the bottom of the gate cover 6. The limit plate 77 continues to drive the gate plate 5, the gate cover 6, the rollers 81, the telescopic frame 82 and the two retracted inclined slot frames 83 to move towards the direction close to the upper cover plate 4. The guide rail 2 guides the gate plate 5. After the gate plate 5 is separated from the bottom of the frame 1, the storage The water can be discharged; when it is necessary to store water again, the operator starts the output shafts of the two motors 71 to rotate in the opposite direction. The output shafts of the two motors 71 rotate in the opposite direction to drive the two threaded rods 73 to rotate in the opposite direction. The two threaded rods 73 rotate in the opposite direction to drive the two drive nuts 74 to move away from the upper cover plate 4. The two drive nuts 74 drive the horizontal plate 75, the vertical plate 76, the limit plate 77, the gate plate 5, the gate cover 6, the roller 81, the telescopic frame 82 and the inclined slot frame 83 to move in the direction away from the upper cover plate 4. When the gate plate 5 contacts the bottom of the frame 1, the gate plate 5 and the gate cover 6 stop moving, and the horizontal plate 75, the vertical plate 76, the limit plate 77 and the roller 81 The shaft 81 continues to move away from the upper cover plate 4, the limit plate 77 will separate from the gate cover 6, and the four rollers 81 slide from the top of the chute frame 83 to the bottom of the chute frame 83. Under the action of the chute frame 83, the two telescopic frames 82 will move away from each other, and the two telescopic frames 82 will reset to the extended state, and the operator will turn off the motor 71; the four rollers 81 slide from the top of the chute frame 83 to the bottom of the chute frame 83. Under the action of the chute frame 83, the two telescopic frames 82 will move away from each other, and the two telescopic frames 82 will extend from the bottom of the frame 1, and the silt will be deposited on the sides of the two telescopic frames 82;When the four rollers 81 slide from the bottom of the chute frame 83 to the top of the chute frame 83, the two telescopic frames 82 will move towards each other under the action of the chute frame 83. When the outer walls of the two telescopic frames 82 are flush with the two outer walls of the gate plate 5, the deposited sludge can be separated from the outer walls of the two telescopic frames 82. When the gate plate 5 and the two telescopic frames 82 move towards the direction close to the upper cover plate 4, the sludge carried on the gate plate 5 and the two telescopic frames 82 can be reduced, thereby effectively reducing the sludge from entering the guide rail 2, thereby improving the smoothness and stability of the movement of the gate plate 5 and reducing the wear and corrosion of the gate. ;

[0038] When the horizontal plate 75 moves, it will drive the two blocking pieces 9 to move. The two blocking pieces 9 can cover the two chute grooves 3, thereby preventing impurities from passing through the chute grooves 3 and then entering the frame 1 when the gate plate 5 moves.

[0039] Embodiment 2: Based on embodiment 1, Figure 8-Figure 13 As shown, it also includes a cleaning mechanism, which is arranged on the frame 1 and the threaded rod 73.

Two cylinders 103 are installed in the lower part of the frame 1, and a piston rack 104 is slidably provided in the two cylinders 103. The upper parts of the two piston racks 104 are respectively connected to the two bidirectional nuts 102 is fixedly connected, a liquid inlet check valve 105 is installed at the bottom of the two cylinders 103, and the liquid inlet check valve 105 is communicated with the cylinder 103. A liquid inlet pipe 106 is installed on each of the two liquid inlet check valves 105, and the liquid inlet pipe 106 is communicated with the liquid inlet check valve 105. The other ends of the two liquid inlet pipes 106 pass through the frame 1 respectively, and two liquid outlet check valves 107 are installed at the bottom of the two cylinders 103 respectively, and the liquid outlet check valve 107 is communicated with the cylinder 103. A liquid outlet pipe 108 is installed on each of the liquid outlet check valves 107, and the liquid outlet check valve 107 is communicated with the liquid outlet pipe 108. A multi-hole spray plate 109 is respectively embedded in the middle of the two side surfaces of the frame 1, and the two multi-hole spray plates 109 are symmetrically arranged. The multi-hole spray plate 109 on the same side is connected to the two liquid outlet pipes 108 on the same side, and the multi-hole spray plate 109 is communicated with the liquid outlet pipe 108.

[0040] A mesh plate 11 is also included. The ends of the two liquid inlet pipes 106 are both embedded with a mesh plate 11 .

[0041] The cleaning mechanism is also included, which is arranged on the frame 1 and the piston frame 104. The cleaning mechanism is used to clean impurities on the screen plate 11. The cleaning mechanism includes a rotating shaft 121, a cleaning round frame 122, a column gear 123 and a rack 124. Two rotating shafts 121 are rotatably provided on the frame 1 through bearings. One end of the two rotating shafts 121 is respectively installed with a cleaning round frame 122. A plurality of cleaning bristles are provided on the two cleaning round frames 122 on one side close to the liquid inlet pipe 106. A column gear 123 is respectively installed on the other end of the two rotating shafts 121. The two column gears 123 are both located in the frame 1. A rack 124 is respectively installed on the side away from each other on the two piston frames 104. The middle parts of the two racks 124 are both missing teeth, and the two column gears 123 are respectively located at the missing teeth in the middle parts of the two racks 124.

[0042] It also includes a baffle plate 13 and a counterweight block 14. A baffle plate 13 is respectively installed on the inner side of the two cleaning circular frames 122. The two baffle plates 13 are respectively used to block the water inlets of the two liquid inlet pipes 106. A counterweight block 14 is fixedly installed on one side of the outside of the two cleaning circular frames 122 close to the baffle plate 13.

[0043] The shielding plate 13 and the liquid inlet pipe 106 do not contact each other.

[0044] When the two threaded rods 73 rotate, the two bidirectional screw rods 101 will be driven to rotate. The rotation of the two bidirectional screw rods 101 drives the two bidirectional nuts 102 to move up and down continuously. The two bidirectional nuts 102 drive the two piston racks 104 to move up and down continuously. When the piston rack 104 moves upward, water enters the cylinder 103 through the liquid inlet pipe 106 and the liquid inlet one-way valve 105. When the piston rack 104 moves downward, water is sprayed from the two porous spray plates 109 to both sides of the gate plate 5 through the liquid outlet one-way valve 107 and the liquid outlet pipe 108. This is repeated, and the two sides of the gate plate 5 can be continuously sprayed with water for cleaning, which further reduces the residual silt and impurities on both sides of the gate plate 5, further reduces the silt entering the guide rail 2, further improves the smoothness and stability of the movement of the gate plate 5, and further reduces the wear and corrosion of the gate.

[0045] Under the action of the mesh plate 11 , impurities can be intercepted, thereby preventing larger impurities from entering the cylinder 103 through the liquid inlet pipe 106 .

[0046] The two piston racks 104 move up and down, driving the two racks 124 to move up and down. The two racks 124 move up and down, driving the two column gears 123 to rotate forward and reversely. The two column gears 123 drive the two rotating shafts 121 to rotate forward and reversely. The two rotating shafts 121 drive the two cleaning circular racks 122 to continuously rotate forward and reversely. The cleaning bristles on the two cleaning circular racks 122 can scrape off the impurities intercepted on the mesh plate 11, so as to avoid the mesh plate 11 being blocked and reducing the water inlet amount of the liquid inlet pipe 106, thereby avoiding the situation where the porous spray plate 109 sprays insufficient water and reduces the cleaning effect of the silt and impurities on both sides of the gate plate 5, further improving the smoothness and stability of the movement of the gate plate 5, and further reducing the wear and corrosion of the gate.

[0047] When the bottom of the gate plate 5 contacts the bottom of the frame 1, the two column gears 123 are respectively located at the missing teeth in the middle of the two racks 124. Under the action of the gravity of the counterweight 14, the cleaning frame 122, the baffle plate 13, the counterweight 14 and the rotating shaft 121 will swing. The baffle plate 13 and the counterweight 14 will swing to a position close to the liquid inlet pipe 106. The baffle plate 13 can block the liquid inlet pipe 106, thereby preventing excessive impurities from accumulating on the liquid inlet pipe 106 and the mesh plate 11 when water is stored. A certain gap is left between the baffle plate 13 and the liquid inlet pipe 106. Therefore, the baffle plate 13 is not easy to affect the water inlet of the liquid inlet pipe 106.

[0048] Embodiment 3: Based on embodiment 2, Figure 9-12 As shown, it also includes a brush plate 15 and a reset spring 16. Two brush plates 15 are slidingly provided between the two fixing frames 72. A plurality of decontamination bristles are provided on the sides of the two brush plates 15 close to each other. The gate plate 5 is located below the two brush plates 15. Reset springs 16 are connected between the two sides of the two brush plates 15 and the two fixing frames 72.

[0049] When the gate plate 5 and the telescopic frame 82 move, they will come into contact with the cleaning bristles on the two brush plates 15. Under the action of the return spring 16, the cleaning bristles on the two brush plates 15 will fit with the two side surfaces of the gate plate 5 and the telescopic frame 82, so that the two side surfaces of the gate plate 5 and the telescopic frame 82 can be fully cleaned and decontaminated, thereby avoiding corrosion of the gate by dirt and extending the service life of the gate.
