Technical Field

[0001] The invention relates to the technical field of sediment cleaning, and in particular to a reservoir sediment rapid cleaning system. Background Art

[0002] As the water flows, different silt will be deposited on the surface of different riverbeds. Due to the large water flow on the flood discharge outlet side of the reservoir, silt often accumulates at the bottom of the reservoir. Excessive silt accumulation slows down the water flow, thus affecting the flood discharge efficiency. The traditional way of cleaning silt is to rely on a stirring rod to stir the silt, causing it to float and flow with the water, and the cleaning effect is poor.

[0003] In a reservoir bottom sediment cleaning device with patent number ZL 201811353322.9, by starting the vertical motor, the rotating rod drives the stirring rod and the sand stirring plate to rotate, and the platform lifting motor is started. The second-level workbench slowly moves downward by 1m. Driven by the rotating rod, the stirring rod and the sand stirring plate stir the sediment at the bottom of the reservoir at a workbench position to a depth of 1m. The sediment is suspended in the water in the middle and upper parts and discharged from the dam with the water flow.

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not constitute a limitation on the present invention.

[0024] like Figure 1As shown, in this embodiment, the model of the controller 2 is COP-800, the signal output end of the controller 2 is electrically connected to the signal input end of the drive motor 13, the high-pressure water pump 15, the winch 26, the distance sensor 30, the camera 31, and the high-pressure suction pump 32, and the power output end of the controller 2 is electrically connected to the power input end of the drive motor 13, the high-pressure water pump 15, the winch 26, the distance sensor 30, the camera 31, and the high-pressure suction pump 32.

[0025] The present invention includes a water-circulating sediment transport device, a filtering device and a rotary sediment collection device located at the bottom of a river. The rotary sediment collection device includes a sand storage box 3 for storing sediment and a sediment excavation device for delivering sand into the sand storage box 3. The water-circulating sediment transport device includes a high-pressure water pump 15 for pumping water into the sand storage box 3, a high-pressure suction pump 32 for pumping mud-water mixture in the sand storage box 3 to above the water surface, a water inlet pipe 17 and a water outlet pipe 20. The water outlet end of the high-pressure water pump 15 is connected to a water inlet 18 on one side of the sand storage box 3 through the water inlet pipe 17, the water inlet end of the high-pressure suction pump 32 is connected to a water outlet 19 on the other side of the sand storage box 3 through the water outlet pipe 20, and the water outlet end of the high-pressure suction pump 32 is connected to the filtering device.

[0026] The water circulation sediment transport device uses the high-pressure water pump 15 to make water flow through the water pipe 16 and the water inlet pipe 17 to flow into the sand storage box 3, and wash away the sediment in the sand storage box 3. The high-pressure suction pump 32 can actively lift the sediment in the sand storage box 3 to above the water surface through the water outlet pipe 20 to achieve the purpose of transporting sediment. At the same time, different filter screens are used to separate the sediment from the water for later processing. The fixed frame 1 is set on the water surface, and the high-pressure water pump 15 is fixed on the fixed frame 1.

[0027] like Figure 2As shown, the sediment excavation device includes a fan-shaped sand hopper 11 for excavating sediment, a rotating cylinder 7 for delivering the excavated sediment to the sand storage box 3, a driving motor 13 for driving the fan-shaped sand hopper 11 to rotate, an annular connection portion 5 and a sealing bearing 6 for connecting the rotating cylinder 7 and the sand storage box 3. A circular opening 4 is provided on the side surface of the sand storage box 3, and an opening portion 8 is provided at the end of the rotating cylinder 7. The circular opening 4 and the opening portion 8 are fixedly connected through the annular connection portion 5. The sealing bearing 6 is sleeved on the outer wall of the annular connection portion 5, and the end of the rotating cylinder 7 is fixedly connected to the outer ring of the sealing bearing 6. A guide spiral belt 9 for actively transporting sediment to the sand storage box 3 is provided in the rotating cylinder 7. A plurality of sediment collection ports 10 are evenly opened along the circumference of the outer wall of the rotating cylinder 7. The fan-shaped sand hopper 11 is fixed at the sediment collection port 10 of the rotating cylinder 7, and the fan-shaped outer wall of the fan-shaped sand hopper 11 is a fan-shaped sand filter net 12. The driving motor 13 is fixed on the sand storage box body 3. The side wall of the fan-shaped sand hopper 11 facing the driving motor 13 is provided with a rack 35. The driving end of the driving motor 13 is provided with a gear meshing with the rack 35. A plurality of guide pieces 34 are fixed around the inner wall of the rotating cylinder 7. The plurality of guide pieces 34 are spirally distributed along the axial direction of the rotating cylinder 7 to form a guide spiral belt 9. The guide pieces 34 are radially inclined, and the radial inclination angle of each guide piece 34 is the same. The rotation of the driving motor 13 of the rotary sand collection device drives the fan-shaped sand hopper 11 to rotate. When the fan-shaped sand hopper 11 is lowered to the bottom of the reservoir, the silt can be excavated and temporarily stored in the sand storage box body 3 through the opening 8. Through the rotation of the guide spiral belt 9, the silt can actively flow to the sand storage box body 3, thereby preventing blockage.

[0028] like Figure 3 As shown, it also includes a rectangular frame 28, a fixed frame 1 and a winch 26 arranged on the water surface. The top of the sand storage box 3 is fixedly connected to the rectangular frame 28, and the winch 26 is fixed on the fixed frame 1. The winch 26 is fixedly connected to the rectangular frame 28 through a steel wire rope 27. A counterweight 33 is provided on the top of the rectangular frame 28, a camera 31 is provided on the side wall of the rectangular frame 28, and a distance sensor 30 is provided at the bottom of the rectangular frame 28. The steel wire rope 27 is driven to scale by the rotation of the winch 26, so that the rotary sediment collection device can be adjusted in the vertical direction. With the change of different positions, the cleaning height also changes, which solves the problem that the cleaning device cannot change with the change of the bottom of the reservoir.

[0029] like Figure 4As shown, the filtering device includes a first filter box 14 and a second filter box 23 closely arranged on one side of the first filter box 14. The first filter box 14 is fixedly connected to the fixing frame 1, and the upper end of the water outlet pipe 20 is plug-connected to the first filter box 14. The water outlet of the high-pressure suction pump 32 is connected to the first filter box 14, and the first filter box 14 and the second filter box 23 are provided with a water outlet 22 for connecting the two filter boxes on the adjacent side walls, and the second filter box 23 is provided with a drain outlet 25 on the side wall opposite to the water outlet 22. A coarse filter screen 21 is horizontally arranged in the first filter box 14, and a fine filter screen 24 is horizontally arranged in the second filter box 23. The assembly height of the coarse filter screen 21 is higher than the water outlet 22 and lower than the water outlet of the high-pressure suction pump 32, and the assembly height of the fine filter screen 24 is lower than the water outlet 22 and higher than the drain outlet 25.

[0030] When it is necessary to clean the silt at the bottom of the reservoir, first fix the fixing frame 1 to the ship so that one end of the fixing frame 1 is suspended above the water surface. At this time, the winch 26 is in a retracted state. When it reaches the approximate water area, the winch 26 releases the wire rope 27. Through the observation of the camera 31 and the sensing of the distance sensor 30, it can accurately reach the position that needs to be cleaned. When it moves to a suitable position, the controller 2 controls the driving motor 13 to rotate. The rotation of the driving motor 13 directly drives the rotating drum 7 to rotate. Due to the effect of the sealed bearing 6, the rotating drum 7 can be rotated. The rotation of the moving cylinder 7 is smoother, and the rotation of the rotating cylinder 7 drives the fan-shaped sand bucket 11 to rotate. While the fan-shaped sand bucket 11 is rotating, one end of the fan-shaped sand bucket 11 will contact the bottom surface of the reservoir. With the rotation and horizontal movement of the fan-shaped sand bucket 11, a large amount of sediment will enter the rotating cylinder 7 through the sediment collection port 10. With the action of the guide spiral belt 9, the sediment will actively move to one side of the sand storage box body 3, and will eventually be temporarily stored in the sand storage box body 3. Due to the action of the sand filter net 12, part of the water will be discharged, so that the sediment will be closer to the fan-shaped sand bucket 11, thereby facilitating the collection of sediment.

[0031] When the silt in the sand storage box 3 is stored to a certain extent, firstly, one end of the water pipe 16 is placed under the water surface, and the controller 2 controls the high-pressure water pump 15 to work. The work of the high-pressure water pump 15 can make a large amount of water enter the sand storage box 3 through the water pipe 16, the high-pressure water pump 15, the water inlet pipe 17, and the water inlet. At the same time, the high-pressure suction pump 32 works, and the work of the high-pressure suction pump 32 makes the silt actively move upward through the water outlet 19 and the water outlet pipe 20. Through the cooperation of the high-pressure water pump 15 and the high-pressure suction pump 32, the silt can be quickly lifted into the first filter box 14, and then the silt-water mixture is filtered through the coarse filter 21, part of the water flows to the bottom through the water permeable hole 29, and a large amount of silt is filtered above the coarse filter 21 and cleaned at the same time. The water after the initial filtration passes through the water outlet 22 and flows into the second filter box 23. After that, the muddy water is filtered again through the fine filter 24 and finally discharged through the drain 25.

[0032] Through the sensing of the distance sensor 30, the position change between the ship and the bottom of the reservoir can be sensed in real time. The distance sensor 30 transmits the data of the distance change to each controller 2, and then controls the winch 26 to rotate. The rotation of the winch 26 directly drives the rectangular frame 28 to move up and down, thereby adjusting the relative height of the rotary sediment collection device; the counterweight block 33 can keep the rectangular frame 28 in a horizontal state.
