Description

Technical Field

[0001] This application relates to the field of river dredging equipment technology, and in particular to a river dredging equipment for water conservancy construction. Background Technology

[0002] Water conservancy construction refers to engineering projects built to mitigate water hazards and develop and utilize water resources. Based on their service objectives, they can be categorized into flood control projects, farmland irrigation projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, and coastal reclamation projects. Water conservancy projects that simultaneously serve multiple purposes such as flood control, water supply, irrigation, and power generation are called comprehensive utilization water conservancy projects. Water conservancy projects require the construction of various types of hydraulic structures, including dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways, to achieve their objectives.

[0003] Most existing dredging methods utilize sludge pumps or spiral lifting equipment to suck out and clean the sludge from the bottom of the river. However, the existing suction methods can only clean the upper layer of sludge. In the process of cleaning, the sludge at the bottom of the river inevitably contains debris such as stones, branches, and household garbage, requiring repeated adjustments to reduce clogging of the sludge pumps or lifting equipment.

[0004] The existing technical solutions mentioned above have the following drawbacks: the existing suction dredging method is often easily blocked by debris and stones, resulting in reduced dredging efficiency and even damage to the dredging equipment. Utility Model Content

[0005] In order to reduce the risk of dredging blockage or even damage caused by debris and stones, and to improve dredging efficiency, this application provides a dredging device for water conservancy construction rivers.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: A dredging device for water conservancy construction includes a centrifuge tank, a sludge pipe connected to the centrifuge tank, a sludge pump connected to one end of the sludge pipe, a suction port on the centrifuge tank, a vertical plate fixed inside the suction port, at least two vertical plates spaced apart, the plate surfaces of the vertical plates inclined to the tangent of the centrifuge tank, a discharge hole on the centrifuge tank, at least two discharge holes, a housing fixed to the centrifuge tank, a motor installed inside the housing, the output shaft of the motor connected to a rotating shaft, a rotating frame fixed to one end of the rotating shaft, strip plates fixed to the rotating frame, at least two strip plates spaced apart, and crushing teeth fixed to the strip plates.

[0007] By adopting the above technical solution, the strip plate with crushing teeth rotates at the bottom of the river, breaking up large pieces of silt and rocks. The stirred sludge is drawn out from the inlet of the centrifuge tank. The vertical plate can prevent large hard objects from entering the centrifuge tank. At the same time, the vertical plate guides the water and sludge entering the centrifuge tank, so that the water and sludge enter tangentially along the centrifuge tank and generate a rotating vortex inside the centrifuge tank. Based on the principle of centrifugal force, the denser hard objects such as rocks and sand in the centrifuge tank slide along the inner wall of the centrifuge tank and are thrown out from the discharge hole. Light silt and water are sucked out from the top of the centrifuge tank by the sludge pump. This can reduce the entry of rocks and sand into the sludge pump body, reduce the risk of dredging blockage or even damage caused by debris and rocks, and improve dredging efficiency.

[0008] Optionally, the strip plate is hinged to the rotating frame.

[0009] By adopting the above technical solution, the rotating frame is hinged to the strip plate. When the strip plate encounters greater resistance, it can rotate on the rotating frame, which can reduce the risk of damage caused by excessive force on the strip plate and extend the service life of the dredging equipment.

[0010] Optionally, a cutting blade is fixedly attached to the strip plate.

[0011] By adopting the above technical solution, the cutting blade can cut through flexible debris such as dead branches and plastics at the bottom of the river, enhance the shearing ability of the dredging equipment, reduce the risk of dredging blockage or even damage caused by debris, and improve dredging efficiency.

[0012] Optionally, at least two motors are spaced apart, with the two motors rotating in opposite directions, and the surfaces of the strip plates connected to the two rotating frames tilting in opposite directions.

[0013] By adopting the above technical solution, two motors drive two rotating frames to rotate in opposite directions, which can increase the stability of the dredging equipment when working at the bottom of the river and reduce the risk of flexible debris such as dead branches and plastics from the bottom of the river getting tangled in the rotating frames.

[0014] Optionally, a filter barrel is fixedly connected inside the centrifuge tank, and the filter barrel is connected to the sludge pipe.

[0015] By adopting the above technical solution, the filter barrel with filter holes can prevent large-diameter debris and stones from entering the sludge pipe and sludge pump, reducing the risk of sludge blockage or even damage caused by debris and stones.

[0016] Optionally, a blade holder is rotatably installed inside the filter barrel, and a cutter is fixedly connected to the blade holder. One end of the blade holder is located inside the sludge pipe and is fixedly connected to an impeller.

[0017] By adopting the above technical solution, the impeller drives the blade holder to rotate with the flow of liquid in the sludge pipe. The cutter on the blade holder rotates along the inner wall of the filter barrel, which can cut off flexible debris such as dead branches and plastics that enter the filter barrel through the filter holes, reducing the risk of sludge blockage or even damage caused by debris.

[0018] Optionally, a baffle is fixedly connected to the housing.

[0019] By adopting the above technical solutions, the baffle can increase the stability of the connection between the centrifuge tank and the box, reduce the risk of damage to the shaft and rotating frame caused by impact when the dredging equipment moves, reduce the damage caused by the dredging equipment hitting large rocks or debris when moving at the bottom of the river, and extend the service life of the dredging equipment.

[0020] Optionally, both the centrifuge tank and the housing are fixedly connected to lifting rings.

[0021] By adopting the above technical solution, ropes are passed through the lifting rings and connected to the lifting or traction equipment, which facilitates the lifting and movement of the dredging equipment.

[0022] In summary, this application has the following technical effects: By incorporating a centrifuge tank, rotating frame, strip plate, and crushing teeth, the strip plate with crushing teeth rotates at the bottom of the river channel, breaking up large pieces of silt, stones, and other large debris. Water and sludge enter tangentially into the centrifuge tank, generating a rotating vortex inside. Harder materials such as stones and sand slide along the inner wall of the centrifuge tank and are thrown out through the discharge hole. Lighter silt and water are sucked out from the top of the centrifuge tank by a sludge pump. This reduces the amount of stones and sand entering the sludge pump body, lowers the risk of sludge blockage or even damage caused by debris and stones, and improves sludge removal efficiency. By incorporating a cutting blade, the blade can cut through flexible debris such as dead branches and plastic at the bottom of the river, enhancing the shearing ability of the dredging equipment, reducing the risk of dredging blockage or even damage caused by debris, and improving dredging efficiency. By installing baffles, the risk of damage to the shaft and rotating frame caused by impacts during the movement of the dredging equipment is reduced, and damage caused by collisions with large rocks or debris when the dredging equipment moves at the bottom of the river is reduced, thus extending the service life of the dredging equipment.

Detailed Implementation

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a river dredging device for water conservancy construction, referring to... Figure 1 and Figure 2 The sludge removal equipment includes a centrifuge tank 1, a sludge pipe 2 connected to the top of the centrifuge tank 1, a sludge pump 3 connected to the end of the sludge pipe 2 away from the centrifuge tank 1, an input end of the sludge pump 3 connected to the sludge pipe 2, and a discharge pipe 31 connected to the output end of the sludge pump 3. A box body 4 is welded to the side wall of the top of the centrifuge tank 1. A suction port 11 is opened on the bottom of the centrifuge tank 1 near the box body 4. A vertical plate 12 is welded to the inner wall of the suction port 11. Multiple vertical plates 12 are arranged at intervals. The surface of the vertical plate 12 is inclined in the tangential direction of the perimeter wall of the centrifuge tank 1. A discharge hole 13 is opened on the bottom of the centrifuge tank 1 away from the box body 4. Multiple discharge holes 13 are arranged at intervals. A baffle 47 is fixed to the bottom of the box body 4 by bolts. Two baffles 47 are arranged at intervals. The side wall of the baffle 47 near the centrifuge tank 1 is fixed to the centrifuge tank 1 by bolts. Lifting rings are welded to the top of both the centrifuge tank 1 and the box body 4.

[0027] Reference Figure 2 A filter barrel 5 is bolted inside the centrifuge tank 1. The top of the filter barrel 5 is connected to the sludge pipe 2. Filter holes 51 are opened on the peripheral wall of the filter barrel 5. Multiple filter holes 51 are arranged at intervals. A knife holder 6 is rotatably arranged inside the filter barrel 5. A cutter 61 is bolted to the knife holder 6. Two cutters 61 are arranged symmetrically. The cutter 61 slides along the inner wall of the filter barrel 5. The top of the knife holder 6 extends into the sludge pipe 2 and is bolted to an impeller 62.

[0028] Reference Figure 2Two motors 41 are installed inside the housing 4, spaced apart, with opposite rotation directions. The output shaft of the motor 41 is connected to a rotating shaft 42 via a coupling. One end of the rotating shaft 42 extends out of the bottom surface of the housing 4 and is fixed to a rotating frame 43 by bolts. Three strip plates 44 are hinged to the rotating frame 43, with their surfaces inclined towards the housing 4. The inclination directions of the strip plates 44 connected to the two rotating frames 43 are opposite. One end of the strip plate 44 along its length is hinged to the rotating frame 43. Multiple breaking teeth 45 are fixed to the side wall of the strip plate 44 away from the housing 4 by bolts. A cutting blade 46 is welded to the side wall of the strip plate 44 away from the housing 4.

[0029] When using this dredging equipment, place it at the bottom of the riverbed to be cleaned. Thread ropes through the lifting rings and connect them to hoisting or traction equipment for easy lifting and movement. Place the sludge pump 3 and discharge pipe 31 on the bank where the sludge is piled or on the workboat. Start the sludge pump 3 and motor 41. The motor 41 will drive the rotating frame 43 connected to the strip plate 44 to rotate, causing the strip plate 44 with crushing teeth 45 to rotate at the bottom of the riverbed, breaking up large pieces of sludge and large debris such as stones. The two motors 41 drive the two rotating frames 43 to rotate in opposite directions, increasing the stability of the dredging equipment when working at the bottom of the riverbed and reducing the risk of flexible debris such as dead branches and plastic from the riverbed becoming entangled in the rotating frame 43. The stirred sludge enters the centrifuge tank 1 through the suction port 11. The vertical plate 12 can prevent large hard objects from entering the centrifuge tank 1. At the same time, the vertical plate 12 guides the water and sludge entering the centrifuge tank 1, so that the water and sludge enter tangentially along the centrifuge tank 1 and generate a rotating vortex inside the centrifuge tank 1. Based on the principle of centrifugal force, the dense hard objects such as stones and sand in the centrifuge tank 1 slide along the inner wall of the centrifuge tank 1 and are thrown out through the discharge port 13. The light sludge and water are sucked out from the top of the centrifuge tank 1 by the sludge pump 3. This can reduce the entry of stones and sand into the sludge pump 3, reduce the risk of sludge blockage or even damage caused by debris and stones, and improve sludge removal efficiency.

[0030] The rotating frame 43 is hinged to the strip plate 44. When the strip plate 44 encounters significant resistance, it can rotate on the rotating frame 43, reducing the risk of damage caused by excessive force on the strip plate 44 and extending the service life of the dredging equipment. The cutting blade 46 can cut through flexible debris such as dead branches and plastic at the bottom of the river, enhancing the shearing ability of the dredging equipment, reducing the risk of dredging blockage or even damage caused by debris, and improving dredging efficiency. The baffle 47 increases the stability of the connection between the centrifuge tank 1 and the box 4, reducing the risk of damage to the rotating shaft 42 and the rotating frame 43 due to impact when the dredging equipment moves, reducing damage caused by collisions with large rocks or debris when the dredging equipment moves at the bottom of the river, and extending the service life of the dredging equipment.

[0031] By installing a filter bucket 5 with filter holes 51, larger diameter debris and stones can be prevented from entering the sludge pipe 2 and sludge pump 3, reducing the risk of sludge blockage or even damage caused by debris and stones. The impeller 62 drives the blade holder 6 to rotate with the flow of liquid in the sludge pipe 2. The cutter 61 on the blade holder 6 rotates along the inner wall of the filter bucket 5, which can cut off flexible debris such as dead branches and plastics that enter the filter bucket 5 through the filter holes 51, reducing the risk of sludge blockage or even damage caused by debris.
