Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and sluice gates, in particular to a device for cleaning debris at water conservancy and sluice gates. Background Art

[0002] A sluice is a low-head hydraulic structure built on a river or canal that uses gates to control flow and regulate water levels. Closing the gates can prevent floods, tides, or raise upstream water levels to meet the needs of irrigation, power generation, shipping, aquaculture, environmental protection, industry, and domestic water. Opening the gates can release floodwater, waterlogging, abandoned water, or wastewater, or supply water to the downstream river or canal.

[0003] There will be some debris floating in the river channel. If the gate is not opened for a long time, the debris will accumulate at the gate. When the gate needs to be opened, the accumulated debris will flow downstream with the water flow, affecting the water quality. Moreover, if the debris accumulates too much, it will affect the normal speed of the water flow when the gate is opened, and the flow of downstream water cannot be controlled normally according to the opening space of the gate.

It also prevents the accumulation of debris from affecting the water flow speed, ensuring normal control of the downstream water flow rate. The cleaning is carried out after the gate is raised, and the water is released and cleaned at the same time, saving time. The sewage collecting plate is pulled up by a cable, and the debris is collected on the bottom plate, between the sewage pushing plate and the movable plate. After the gate is raised, the movable plate is opened and laid on the ground. The sewage pushing plate is pushed by multi-stage hydraulic rods and push plates to push out the debris for cleaning. There is no need for cleaning personnel to enter between the gate and the sewage collecting plate to clean, reducing the workload of cleaning personnel. Through the setting of water filter holes, water is filtered when the gate is raised. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figure 1-3 As shown, a debris cleaning device for a water conservancy sluice disclosed by the utility model includes a dam body 1, a trough body 2 and a gate 3 on both sides of the river channel. The trough body 2 is provided with two and respectively fixed on the side walls of the dam body 1 on both sides. The gate 3 can be lifted and installed in the trough body 2. A bracket 4 in an inverted concave shape is fixedly installed on the top of the dam body 1. The bracket 4 is arranged across the river channel. A bottom plate 5 is fixedly installed on the upstream side of the bottom of the gate 3. A sewage collecting plate 6 is rotatably installed on the side of the bottom plate 5 away from the gate 3. Two lifting ears 7 are installed on the side of the sewage collecting plate 6 away from the bottom plate 5. A cable 8 is fixedly passed through the lifting ear 7. The end of the cable 8 away from the lifting ear 7 is connected to a cable retraction structure, and the cable retraction structure is installed on the top of the bracket 4.

[0020] The cable retraction and extension structure includes a dual-axis motor 9, two rotating rods 10 and multiple supports 11. The rotating rod 10 is fixedly installed on the output ends on both sides of the dual-axis motor 9. The supports 11 are equidistantly arranged on both sides of the dual-axis motor 9. The rotating rod 10 passes through the supports 11 and is rotatably connected to the supports 11. The ends of the two cables 8 away from the lifting ears 7 are respectively fixed to the outer circles of the rotating rods 10 on both sides.

[0021] A dirt pushing plate 12 and a movable plate 13 are respectively installed on both sides of the top of the bottom plate 5. Two slide rails 14 are horizontally opened on the upstream side of the gate 3. The dirt pushing plate 12 is slidably installed in the slide rails 14. The movable plate 13 is hinged to the bottom plate 5, and the outer side of the movable plate 13 abuts against the side wall of the trough body 2.

[0022] A base 15 is fixedly installed on the dam body 1, and a multi-stage hydraulic rod 16 is fixedly installed on the top of the base 15. A push plate 17 is fixedly installed on the protruding side of the multi-stage hydraulic rod 16. A plurality of bolts 18 are threadedly connected through the push plate 17. A plurality of threaded holes are opened on the side of the sewage pushing plate 12 close to the trough body 2, and the bolts 18 can be threadedly connected in the threaded holes.

[0023] The bottom plate 5, the dirt collecting plate 6, the dirt pushing plate 12 and the movable plate 13 are all provided with a plurality of water filtering holes.

[0024] Inverted hydraulic telescopic rods 19 are fixedly installed on both sides of the top of the gate 3. The end of the hydraulic telescopic rod 19 away from the gate 3 is fixed to the bottom of the bracket 4. The hydraulic telescopic rod 19 and the multi-stage hydraulic rod 16 are both connected to a hydraulic cylinder.

[0025] A power supply is installed in the base 15, and the dual-axis motor 9, the multi-stage hydraulic rod 16, the hydraulic telescopic rod 19 and the hydraulic cylinder are all powered by the power supply.

[0026] Specific implementation of this example: When the gate 3 is closed, debris gradually accumulates on the sewage collecting plate 6 and the bottom plate 5. When the gate 3 needs to be raised, the dual-axis motor 9 is started to drive the rotating rod 10 to rotate, thereby retracting the cable 8. The cable 8 drives the sewage collecting plate 6 to rise, picks up the debris and piles it on the bottom plate 5, between the sewage pushing plate 12 and the movable plate 13. The gate 3 is opened to release water and drives the bottom plate 5, the sewage collecting plate 6, the sewage pushing plate 12, the movable plate 13 and the accumulated debris to rise. Since the bottom of the movable plate 13 is hinged to the bottom plate 5, as the gate 3 is raised, the movable plate 13 rotates outward and is aligned with the ground The contact is in the open state. After the gate 3 is fully raised, the bolt 18 on the push plate 17 is threaded into the threaded hole of the sewage pushing plate 12, and the multi-stage hydraulic rod 16 is started to push the sewage pushing plate 12. The sewage pushing plate 12 pushes the debris to the side of the movable plate 13 and pushes the debris out from the side of the movable plate 13. Then the multi-stage hydraulic rod 16 contracts to drive the sewage pushing plate 12 back to its original position and remove the bolt 18. The cleaning staff cleans up the debris; when closing the gate 3, first start the dual-axis motor 9 to flatten the sewage collecting plate 6. During the descent of the gate 3, the movable plate 13 is subjected to force and rotates and returns to its original position as the gate 3 descends.
