Two rotating rods 4 are rotatably penetrated on the mounting frame 1, and a transmission roller 2 is sleeved and fixed on the rotating rod 4. The transmission roller 2 and the interception belt 6 are frictionally transmitted. A driving mechanism is installed on one side of the interception belt 6, and the driving mechanism is used to drive the rotating rod 4 to rotate.

[0046] Under the action of the driving mechanism, the rotating rod 4 drives the driving roller 2 to rotate, and the intercepting belt 6 then drives the garbage in the water flow to move upward. There is no need for staff to manually clean the garbage, which effectively improves the efficiency of handling the garbage.

[0047] A plurality of adjustment rods 3 are mounted on the mounting frame 1, and the adjustment rods 3 are slidably matched with the interception belt 6, and the interception belt 6 is arranged in a Z-shaped structure. The arrangement of the adjustment rods 3 makes the interception belt 6 arranged in a Z-shaped structure, which effectively reduces the difficulty of collecting and processing the garbage.

[0048] A guide block 7 is also installed on one side of the interception belt 6, and a plurality of rotating columns 9 are rotatably embedded on the guide block 7. The arrangement of the guide block 7 and the rotating columns 9 enables the garbage at the bottom of the river to be smoothly moved to the interception belt 6, preventing the garbage at the bottom from being accumulated and blocked.

[0049] Reference Figure 1 , Figure 3 and Figure 4The driving mechanism includes a first driving mechanism, which includes a support frame 15, a load-bearing rod 17 is rotatably connected to the support frame 15, and a driving blade 18 is fixedly connected to the load-bearing rod 17. A connecting frame 24 is fixedly arranged on one side of the support frame 15, and a first bevel gear 25 is rotatably connected to the connecting frame 24. A first driving wheel 22 is fixedly arranged on the first bevel gear 25 and the load-bearing rod 17, and a first belt 23 is installed on one side of the connecting frame 24. The first driving wheel 22 and the first belt 23 are frictionally driven.

A third bevel gear 19 is installed on the other side of the spline rod 21, and a fourth bevel gear 20 is sleeved and fixed on one of the rotating rods 4, and the fourth bevel gear 20 is vertically meshed with the third bevel gear 19.

[0050] The impact of water flow drives the blades 18, so that the load-bearing rod 17 drives the corresponding first driving wheel 22 to rotate. Under the connection action of the first belt 23, the first bevel gear 25 rotates, and the spline rod 21 rotates immediately. Under the connection action of the fourth bevel gear 20 and the third bevel gear 19, the rotating rod 4 immediately drives the transmission roller 2 to rotate, and drives the intercepting belt 6 to rotate to transport the garbage, which can utilize the impact force of the water flow and reduce energy consumption.

[0051] A fixing sleeve 14 is also installed on one side of the mounting frame 1, and a supporting frame 15 is slidably connected to the fixing sleeve 14. A plurality of buoys 16 are fixedly installed on the supporting frame 15. A spline sleeve 27 is rotatably passed through the other side of the fixing sleeve 14. The spline sleeve 27 is fixedly connected to the third bevel gear 19, and the spline rod 21 is slidably connected to the spline sleeve 27.

[0052] The arrangement of the buoy 16, the spline rod 21 and the spline sleeve 27 enables the contact distance between the driving blade 18 and the water to always remain consistent, which is conducive to ensuring full utilization of the impact of the water flow.

[0053] The driving mechanism also includes a second driving mechanism, which also includes a first gear 13 that is sleeved and fixed on another rotating rod 4. An electric push rod 10 is fixedly installed on the mounting frame 1. The output end of the electric push rod 10 is fixedly connected to the motor 11. The output end of the motor 11 is fixedly connected to the second gear 12. The second gear 12 is meshed with the first gear 13.

[0054] When the water flow is weak and cannot drive the transmission roller 2 to rotate, under the action of the electric push rod 10, the motor 11 and the second gear 12 move toward the first gear 13, so that the transmission roller 2 is driven by the motor 11, so that the technical solution can be applied to various situations.

[0055] Reference Figure 1 , Figure 5 and Figure 6 A transport assembly 8 is also installed below the other side of the interception belt 6. The transport assembly 8 includes an interception frame 801, on which a transport belt 806 is installed. The transport belt 806 is densely covered with leakage holes 807. A connecting roller 812 is rotatably connected to the interception frame 801. A rotating mechanism is also installed on one side of the interception frame 801. The rotating mechanism is used to drive the connecting roller 812 to rotate, and the connecting roller 812 and the transport belt 806 are frictionally transmitted.

[0056] The rotating mechanism includes a second driving wheel 802 which is sleeved and fixed on one of the rotating rods 4, a third driving wheel 813 is rotatably connected to the intercepting frame 801, a second belt 803 is installed on one side of the conveying belt 806, the second driving wheel 802 and the third driving wheel 813 are both frictionally driven with the second belt 803, a worm gear 808 is sleeved and fixed on one of the connecting rollers 812, a worm 805 is fixed on the third driving wheel 813, and the worm 805 is meshingly connected with the worm wheel 808.

[0057] A plurality of driving rods 804 are rotatably provided on the intercepting frame 801, a plurality of shaking wheels 809 are fixedly installed on one side of the driving rod 804, a third gear 811 is fixedly sleeved on the driving rod 804 and one of the connecting rollers 812, a connecting gear 810 is meshed and connected between the two third gears 811, and the shaking wheel 809 is in active contact with the conveying belt 806.

[0058] When the rotating rod 4 rotates, under the connection action of the second driving wheel 802, the third driving wheel 813 and the second belt 803, the worm 805 rotates. Since the worm 805 is meshingly connected with the worm wheel 808, the connecting roller 812 rotates, and the conveying belt 806 can then transport the garbage dropped by the intercepting belt 6 to the specified direction, further improving the efficiency of handling garbage such as stones in the water flow.

[0059] During the rotation of the connecting roller 812, under the connection between the connecting gear 810 and the third gear 811, the driving rod 804 will drive the shaking wheel 809 to rotate, causing the garbage above the conveying belt 806 to shake, thereby shaking off the water in the garbage, avoiding the water from increasing the difficulty of subsequent garbage disposal, and improving the practicality of this technical solution.

[0060] The implementation principle of the water purification device for the gate of a water conservancy project in the embodiment of the present application is as follows: when relevant staff need to use the present technical solution to block garbage in the water flow on one side of the gate, first, the garbage at the bottom of the water flow will be moved to the interception belt 6 under the guidance of the guide block 7.

[0061] When the water flow impact drives the blades 18, the bearing rod 17 drives the corresponding first driving wheel 22 to rotate. Under the connection action of the first belt 23, the first bevel gear 25 rotates, and the spline rod 21 rotates immediately. Under the connection action of the fourth bevel gear 20 and the third bevel gear 19, the rotating rod 4 immediately drives the transmission roller 2 to rotate, drives the intercepting belt 6 and then drives the salvage claw 5 to rotate to transport the garbage.

[0062] When the water flow is too weak to drive the transmission roller 2 to rotate, under the action of the electric push rod 10 , the motor 11 and the second gear 12 move toward the first gear 13 , so that the transmission roller 2 is driven by the motor 11 .

[0063] After the garbage on the intercepting belt 6 moves to the top of the conveying belt 806, the garbage falls to the top surface of the conveying belt 806 under the action of gravity. When the rotating rod 4 rotates, under the connection action of the second driving wheel 802, the third driving wheel 813 and the second belt 803, the worm 805 rotates, the connecting roller 812 rotates, and the conveying belt 806 immediately transports the garbage dropped by the intercepting belt 6 to the specified direction.

[0064] During the rotation of the connecting roller 812, under the connection of the connecting gear 810 and the third gear 811, the driving rod 804 drives the shaking wheel 809 to rotate, so that the garbage above the conveying belt 806 is shaken, thereby shaking off the water in the garbage. This process continues, and the operation of processing the garbage at the bottom of the water flow can be completed.
