Description

Technical Field

[0001] This utility model relates to the technical field of equipment for water conservancy and hydropower projects, specifically to a silt removal device for water conservancy and hydropower projects. Background Technology

[0002] Dredging in water conservancy and hydropower projects generally refers to river dredging, which is the treatment of silt deposited at the bottom of river channels. As a carrier of water resources, the river channel causes soil migration and deposition during water flow, which is the main cause of river siltation. The silt accumulated in the river channel over time affects the normal functioning of various functions such as flood control, drainage, irrigation, water supply and navigation. In order to restore the normal function of the river channel, it is necessary to clean up the silt in the river channel.

[0003] Currently, existing silt removal devices for water conservancy and hydropower projects all rely on sludge pumps to remove silt. However, these pumps carry a large amount of water, increasing the silt's weight and making transportation difficult. During transport, wastewater from the silt can seep out, polluting the transport route. Furthermore, existing silt removal devices lack a function for removing water from the silt, which is a significant drawback. Additionally, as silt in riverbeds deepens, it tends to clump together. Directly pumping these clumps can cause blockages and damage to the suction pipes and conduits, affecting silt removal efficiency. Therefore, we propose a new silt removal device for water conservancy and hydropower projects. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 3 This utility model provides a technical solution: a sludge removal device for water conservancy and hydropower projects, including a base 1, two mounting seats 2 fixedly installed on the top of the base 1, and a rotating shaft 3 rotatably installed inside each of the two mounting seats 2. Bearings that cooperate with the rotating shaft 3 are provided inside the mounting seats 2. A sleeve 4 is fixedly installed at one end of the rotating shaft 3, and a first motor 5 is fixedly installed at the bottom of the sleeve 4. A centrifugal dewatering drum 6 is installed inside the sleeve 4, and a drain outlet 7 is provided at the bottom of the sleeve 4. A driven gear 8 is fixedly installed at one end of one of the rotating shafts 3. A second motor 9 is fixedly installed on the top of the base 1 and on one side of the mounting seat 2. A driving gear 10 is fixedly installed at the output end of the second motor 9. A toothed chain 11 is installed on the outer side of the driven gear 8 and the driving gear 10. A movable wheel is provided at the bottom of the base 1. The driven gear 8, the second motor 9, the driving gear 10, and the toothed chain 11 drive the sleeve 4 to rotate at a large angle for discharging the dewatered sludge, making the discharging convenient and quick.

[0020] A mounting bracket 14 is fixedly installed on one side of the top of the base 1. A top plate 15 is fixedly installed on the top of the mounting bracket 14. Two hydraulic telescopic rods 16 are fixedly installed on the top of the top plate 15. A concave seat 17 is fixedly installed at the output end of the hydraulic telescopic rod 16 to the bottom of the top plate 15. A third motor 18 is fixedly installed on one side of the concave seat 17. A rotating rod 19 is fixedly installed at the output end of the third motor 18. Several crushing blades 20 are fixedly installed on the outside of the rotating rod 19. The suction hose cooperates with the rotating rod 19 and the crushing blades 20.

[0021] The outer sides of the first motor 5, the second motor 9, and the third motor 18 are all equipped with waterproof covers to protect against water ingress. A dustproof soft sleeve can be added to the hydraulic telescopic rod 16.

[0022] A sludge pump 12 is installed on the top of the base 1. A conduit 13 is fixedly installed at the output end of the sludge pump 12. A suction hose is installed at the input end of the sludge pump 12, wherein the suction hose has a certain length reserved.

[0023] In summary, the silt removal device used in this water conservancy and hydropower project operates as follows: After moving the device to the silt removal site, first activate the drive system on the hydraulic telescopic rod 16. This drives the hydraulic telescopic rod 16 to extend and retract, causing the concave seat 17 to move downwards, bringing the crushing blade 20 into contact with the silt. Then, activate the third motor 18 to drive the rotating rod 19 to contact the crushing blade 20, breaking up and dispersing the clumps in the silt. This reduces the likelihood of silt clumping that prevents suction. After inserting the suction hose into the silt, activate the silt pump 12 to pump up the silt and guide it through the conduit 13 into the centrifugal dewatering drum 6. When the centrifugal dewatering drum 6 is almost full, manually turn off the silt pump 12. Then, the first motor 5 is turned on to drive the centrifugal dewatering drum 6 to rotate. The centrifugal dewatering drum 6 drives the sludge to rotate, thereby generating centrifugal force that throws the water in the sludge into the sleeve 4. The thrown-out wastewater is discharged through the drain outlet 7, which can perform preliminary dewatering of the sludge and reduce the water content in the sludge. After the sludge in the centrifugal dewatering drum 6 has been dewatered, the first motor 5 is stopped and the second motor 9 is turned on to drive the drive gear 10 to rotate, which in turn drives the driven gear 8 and the rotating shaft 3 to rotate through the gear chain 11. The second motor 9 is a lockable motor, which can make the sleeve 4 rotate and tilt around the rotating shaft 3, thereby discharging the dewatered sludge in the centrifugal dewatering drum 6.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
