[0002] In water conservancy projects, dams are the main measures to prevent floods, protect residents and industrial and agricultural production. Dams can change the direction of water flow and increase the water depth of the same flow. When water flows through the dam, some of the floating garbage in the water will stay in the area with lower water flow rate near the dam. The continuous accumulation of garbage will affect the water quality near the dam and block the river.

[0052] Reference Figure 4 as well as Figure 5 After the motor 24 is started, the motor 24 drives the worm 25 to rotate, the rotation of the worm 25 causes the worm wheel 26 to rotate, the rotation of the worm wheel 26 causes the first rotating column 23 to rotate, the rotation of the first rotating column 23 causes the sprocket 22 to rotate, the rotation of the sprocket 22 causes the chain 21 to run, and the second mounting seat 13 moves in the first slide groove 111.

[0053] The implementation principle of a dam garbage management device for a water conservancy project in an embodiment of the present application is as follows: an operator arranges a suspension box 12 in an area where river garbage gathers, and a storage box 16 is set on the riverside, and the suspension box 12 is submerged in water. Under the action of the fluctuation of the water flow, part of the solid garbage enters the suspension box 12 and the collection box 14. Under the action of gravity, the weight in the collection box 14 increases, and the collection box 14 moves in the fourth slide groove 551. The collection box 14 moves and pulls the traction rope 56. The movement of the traction rope 56 causes the winding wheel 54 to rotate. The rotation of the winding wheel 54 causes the second rotating column 55 to rotate. The rotation of the second rotating column 55 causes the second driving gear 53 to rotate. The rotation of the second driving gear 53 causes the third rack 52 to move. The movement of the third rack 52 causes the closing door 51 to move. After the closed door 51 is closed, the motor 24 is started, and the motor 24 drives the worm 25 to rotate. The rotation of the worm 25 causes the worm wheel 26 to rotate. The rotation of the worm wheel 26 causes the first rotating column 23 to rotate. The rotation of the first rotating column 23 causes the sprocket 22 to rotate. The rotation of the sprocket 22 causes the chain 21 to run. The operation of the chain 21 causes the second mounting seat 13 to slide in the first sliding groove 111.

[0054] When the motor 24 drives the chain 21 to operate and move the second mounting seat 13 and the suspension box 12 toward the storage box 16, the first driving gear 43 and the first rack 44 are meshed with each other, and the first rack 44 causes the first driving gear 43 to rotate. The rotation of the first driving gear 43 causes the screw rod 41 to rise, and the rising of the screw rod 41 causes the suspension box 12 to rise. When the control component 3 causes the discharge door 15 to open to discharge the garbage in the collection box 14 and the suspension box 12 moves away from the storage box 16, the first driving gear 43 is meshed with the second rack 45, and the second rack 45 causes the first driving gear 43 to rotate in the opposite direction. The reverse rotation of the first driving gear 43 causes the screw rod 41 to descend, and the descent of the screw rod 41 causes the suspension box 12 to descend and re-enter the water.

[0055] When the suspension box 12 moves to above the storage box 16, the trigger block 32 abuts against the sliding block 31, the trigger block 32 causes the sliding block 31 to move and compress the first return spring 33, and the sliding block 31 moves away from the discharge door 15 under the pushing action of the trigger block 32. The discharge door 15 loses the blocking effect of the sliding block 31, the discharge door 15 opens, and the garbage in the collection box 14 is discharged into the storage box 16.

[0056] After the garbage in the collection box 14 is discharged into the storage box 16, the motor 24 continues to drive the chain 21 to move, the second mounting seat 13 continues to move along the first slide groove 111, and the suspension box 12 follows the second mounting seat 13 to move above the push plate 34. The discharge door 15 on the collection box 14 contacts the push plate 34, and the suspension box 12 continues to move. Under the action of the inclined surface of the push plate 34, the push plate 34 makes the discharge door 15 re-engage with the sliding block 31, thereby completing a garbage collection and cleaning work; by setting the first drive component 2 and the control component 3, the automatic discharge of the collection box 14 can be controlled. The operator only needs to collect the garbage in the storage box 16 located on the ground, and the operator does not need to go to the water to clean the garbage in the collection box 14, which reduces the cleaning frequency and improves convenience.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
