Description

A dredging pump for waterways Technical Field

[0001] This utility model specifically relates to a dredging pump for waterway dredging, belonging to the field of dredging pump technology. Background Technology

[0002] As a key piece of equipment for maintaining smooth waterways and ensuring safe navigation, the dredging suction pump plays an extremely important role in the field of waterway engineering. Its working principle is to use the suction force of the pump to suck up sediments such as mud and silt from the bottom of the water and transport them through pipelines to designated locations, thereby achieving operations such as deepening, widening and dredging of waterways. It is of great significance for maintaining good navigation conditions and promoting the efficient operation of water transport.

[0003] However, when the sludge pump operates in an area with abundant aquatic plants, a large amount of aquatic plants can easily become tightly entangled on the outside of the pump while it is moving underwater. These flexible yet tough aquatic plants intertwine and hinder the pump. Initially, the speed of the equipment will slow down due to this additional resistance. As the operation continues, more and more aquatic plants will become entangled on the pump. When the amount of entanglement reaches a certain level, the drag force generated is enough to bring the pump to a near standstill, making it unable to move. Worse still, if these entangled aquatic plants cannot be cleared in time, the pump may become firmly "tied" to the bottom of the water and difficult to remove.

[0004] To address the above problems, this application proposes a sludge suction pump for waterway dredging. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a dredging pump for waterways. Through the design of a weed-crushing mechanism, a driving gear rotates, causing a double-toothed ring to rotate. As the double-toothed ring rotates, multiple sets of driven gears distributed around it are synchronously driven, causing the synchronous roller to also drive the crushing teeth to rotate. When the dredging pump body moves underwater and encounters weeds, these rotating crushing teeth can cut and crush the weeds blocking the path, avoiding obstruction caused by weed entanglement and solving the problems mentioned in the background art.

[0006] A dredging pump for waterways includes a pump body; an aquatic plant shredding mechanism is provided on the outer side of the pump body; the aquatic plant shredding mechanism includes multiple sets of synchronously rotating synchronous rollers equidistantly surrounding the outer side of the pump body, and multiple sets of shredding teeth for shredding aquatic plants are installed on the outer wall of the synchronous rollers; a circular plate is provided above the synchronous rollers, and a double-toothed ring is provided on the circular plate; multiple sets of driven teeth are provided on the inner side of the double-toothed ring, and multiple sets of driving teeth are provided on the outer side; multiple sets of driven gears are meshed with the outer side of the double-toothed ring through the driving teeth; a rock-blocking mechanism includes a rhomboid frame located below the pump body to block underwater rocks, and multiple sets of water passage holes are opened on the surface of the rhomboid frame to reduce water resistance; rock-pushing corners are provided on both sides of the rhomboid frame to push away rocks in the path of the pump body during its movement.

[0007] In a preferred embodiment, an outer frame is installed on the outside of the main body of the sludge pump, and a circular plate is fixed above the outer frame. A bottom plate is installed below the outer frame, and a top plate is connected to the circular plate by multiple sets of connecting rods.

[0008] In a preferred embodiment, the number and position of the driven gears correspond to the number and position of the synchronous rollers. A rotating shaft is installed inside the synchronous roller. The upper end of the rotating shaft is connected to the driven gear, and the lower end of the rotating shaft is rotatably connected to the base plate. The base plate is fixedly connected to the rhomboid frame.

[0009] In a preferred embodiment, an L-shaped fixing plate is installed on one side of the upper part of the circular plate, and a waterproof motor is installed on one side of the fixing plate. A drive gear is provided below the waterproof motor, and the output shaft of the waterproof motor is fixedly connected to the drive gear. The drive gear is meshed with the driven gear.

[0010] In a preferred embodiment, a limiting annular groove is formed on the upper surface of the circular plate, and multiple sets of linkage wheels are provided in the limiting annular groove. The linkage wheels are fixedly connected to the lower surface of the double gear ring through axles.

[0011] In a preferred embodiment, three sets of connecting plates are installed above the top plate, and connecting rings are installed above the three sets of connecting plates.

[0012] In a preferred embodiment, a sludge discharge pipe is provided above the top plate, with a flange connected to the upper end of the sludge discharge pipe and the lower end connected to the sludge discharge port of the sludge pump body.

[0013] Beneficial effects:

[0014] 1. By designing a waterweed shredding mechanism, a waterproof motor is used as the power source. After starting, it drives the drive gear to rotate, causing the double gear ring to rotate. The double gear ring has a hollow structure, which ensures that the waterweed shredding function operates normally without obstructing the normal mud discharge operation of the sludge pump, thus ensuring the smooth progress of the sludge suction and discharge process. As the double gear ring rotates, multiple sets of driven gears distributed around it are driven synchronously. The rotation of the driven gears is transmitted through the rotating shaft, causing the synchronous roller to drive the shredding teeth to rotate as well. When the sludge pump body moves on the bottom of the water, if it encounters waterweed obstruction, these rotating shredding teeth can cut and shred the waterweed blocking the path, effectively avoiding the problem of movement obstruction caused by waterweed entanglement.

[0015] 2. By designing a rock-blocking mechanism, when the sludge pump body moves forward underwater, if a large rock appears in the path, the rock-pushing corner will push the rock away, changing its position and causing it to deviate from the direction of the sludge pump body. The diamond-shaped structure of the frame can use its shape advantage to guide large rocks to the sides during movement, preventing large rocks from being sucked up by the sludge pump body, causing impact and wear, leading to equipment damage or interruption of sludge suction operation. At the same time, the diamond frame has water passage holes. During movement, water carrying mud and sand can smoothly flow into the diamond frame through these water passage holes. Subsequently, the powerful suction of the sludge pump body will suck up the water and mud and sand in the frame and discharge them together, thus blocking large rocks without delaying normal sludge suction operation.

Multiple sets of shredding teeth 27 for shredding weeds are installed on the outer wall of the synchronous rollers 26. A circular plate 21 is provided above the synchronous rollers 26. A double-toothed ring 24 is provided on the circular plate 21. Multiple sets of driven teeth are provided on the inner side of the double-toothed ring 24, and multiple sets of driving teeth are provided on the outer side of the double-toothed ring 24. Multiple sets of driven teeth are meshed with the outer side of the double-toothed ring 24 through the driving teeth. Wheel 25; Rock-blocking mechanism 3, including a rhomboid frame 31 located below the main body of the sludge pump 1 to block underwater rocks, and multiple sets of water passage holes 33 are opened on the surface of the rhomboid frame 31 to reduce water resistance. On both sides of the rhomboid frame 31, there are push corners 32 that can push away rocks in the path of the sludge pump 1 during its movement. During the movement of the main body of the sludge pump 1, the water flow carrying mud and sand can smoothly flow into the interior of the rhomboid frame 31 through the water passage holes 33. Then, the powerful suction of the main body of the sludge pump 1 will suck out the water flow and mud and sand in the frame together, which not only blocks large rocks, but also does not delay the normal sludge suction operation.

[0024] Please refer to Figures 1-3. An outer frame is installed on the outside of the main body 1 of the sludge pump, and a circular plate 21 is fixed on the top of the outer frame. A bottom plate 28 is installed below the outer frame, and a top plate 23 is connected to the top of the circular plate 21 by multiple sets of connecting rods 22.

[0025] Please refer to Figures 1-3. The number and position of the driven gears 25 correspond to the number and position of the synchronous rollers 26. A rotating shaft is installed inside the synchronous rollers 26. The upper end of the rotating shaft is connected to the driven gears 25, and the lower end of the rotating shaft is rotatably connected to the base plate 28. The base plate 28 is fixedly connected to the rhomboid frame 31. When the driven gears 25 rotate, they can drive the synchronous rollers 26 to rotate synchronously through the rotating shaft.

[0026] Please refer to Figure 3. An L-shaped fixing plate 211 is installed on one side of the upper part of the circular plate 21, and a waterproof motor 29 is installed on one side of the fixing plate 211. A drive gear 210 is provided below the waterproof motor 29, and the output shaft of the waterproof motor 29 is fixedly connected to the drive gear 210. The drive gear 210 is meshed with the driven gear.

[0027] Please refer to Figure 4. A limiting annular groove 212 is provided on the upper surface of the circular plate 21. Multiple sets of linkage wheels 213 are provided in the limiting annular groove 212. The linkage wheels 213 are fixedly connected to the lower surface of the double gear ring 24 through the wheel axle. The linkage wheels 213 can rotate in the limiting annular groove 212 and will not detach from its interior under the limiting action of the limiting annular groove 212.

[0028] Please refer to Figure 1. Three sets of connecting plates 6 are installed above the top plate 23, and connecting rings 4 are installed above the three sets of connecting plates 6.

[0029] Please refer to Figures 1-4. A sludge discharge pipe 5 is provided above the top plate 23. The upper end of the sludge discharge pipe 5 is connected to a flange, and its lower end is connected to the sludge discharge port of the sludge pump body 1.

[0030] In practical use, the working principle of this utility model is as follows:

[0031] Before being put into use, the connecting ring 4 is connected to the equipment responsible for lowering the sludge pump body 1. At the same time, the pipe for sludge discharge is connected to the sludge discharge pipe 5 through the flange. Then, the sludge pump body 1 is lowered to the predetermined working area at the bottom of the water. When the sludge pump body 1 reaches the bottom of the water and starts to work, the rhombus frame 31 contacts the bottom of the water, and the sludge pump body 1 starts its powerful suction function. At this time, the mud and sand at the bottom of the water will flow into the sludge pump body 1 through the water passage holes 33 on the surface of the rhombus frame 31 under the action of this suction force. Then, it will be discharged smoothly through the sludge discharge pipe 5, completing the basic sludge suction process.

[0032] When the sludge suction operation begins, the waterproof motor 29 drives the connected drive gear 210 to rotate. The drive gear 210 drives the double gear ring 24 to rotate on the circular plate 21 through the driven teeth. During this process, the double gear ring 24 drives the linkage wheel 213 to rotate along the predetermined path of the limiting ring groove 212 through the wheel axle, which improves the stability of the double gear ring 24 during rotation. The drive teeth on the outer side of the double gear ring 24 simultaneously drive multiple sets of driven gears 25 to rotate together. The rotation of the driven gears 25 is transmitted through the rotating shaft, causing the synchronous roller 26 to rotate, which in turn drives the crushing teeth 27 on the outer wall of the synchronous roller 26 to rotate, and then the sludge suction pump body 1... During operation, the rotating crushing teeth 27 can crush the aquatic plants on the outside of the sludge pump body 1, avoiding the problem of the sludge pump body 1 being blocked due to the entanglement of aquatic plants. At the same time, the rhomboid frame 31 located below the sludge pump body 1 always moves synchronously with the sludge pump body 1. The rock-pushing corners 32 designed on both sides of the rhomboid frame 31 push away the rocks on the path of the sludge pump body 1 during the movement. In addition, the rhomboid structure of the rhomboid frame 31 can guide large rocks to shift to both sides due to its shape advantage, avoiding the large rocks being sucked by the sludge pump body 1 and causing impact and wear to the sludge pump body 1.
