Description

Technical Field

[0001] This invention relates to the field of dredging equipment technology, and in particular to a dredging system for water conservancy projects. Background Technology

[0002] Silt is a common sediment in rivers and water bodies, and the silt layers formed by its deposition have multifaceted impacts on hydraulic engineering. First, silt accumulation obstructs water flow, increasing hydraulic resistance and reducing water volume, leading to river siltation, rising water levels, and even flooding. Second, silt is rich in organic matter, which easily decomposes, producing foul odors and harmful gases, affecting the health of the surrounding environment and ecosystem. Furthermore, silt may contain heavy metals, organic pollutants, and other harmful substances, polluting water quality and threatening the safe use of water resources.

[0003] Dredging equipment, as a specialized tool for dredging rivers, lakes, and other bodies of water, has a significant impact on water conservancy projects. It effectively removes or excavates silt from river channels, restoring navigation capacity, reducing water accumulation, lowering water levels, and preventing floods. Furthermore, dredging equipment can remove organic matter and harmful substances from the silt, improving water quality and protecting the ecological environment.

[0004] However, dredging equipment also faces some technical challenges during river dredging. First, due to the uneven distribution of silt in the riverbed, selecting the location and planning the movement path of the dredging equipment presents difficulties, easily leading to low dredging efficiency or incomplete dredging. Second, the dredging equipment is easily affected by the stickiness of the silt during the dredging process, causing blockages or jamming, affecting the continuity and efficiency of the dredging operation. Finally, during river dredging, it is difficult to fix the dredging equipment in the riverbed, making it impossible to determine the dredging location, especially during the dredging process.

The top ends of the plurality of guide brackets 233 are connected to the same guide ring plate 234. A linear drive component that cooperates with the guide ring plate 234 is disposed on the dredging base 100. The structure of the second lifting unit 250 is consistent with the structure of the first lifting unit 230.

[0063] Furthermore, the waste collection assembly 350 includes a filter screen 351 vertically disposed in the preliminary box 340, a push rod 352 disposed in the preliminary box 340, a push frame that slides with the preliminary box 340 at the moving end of the push rod 352, and a waste collection box 353 that cooperates with the push frame disposed on one side of the preliminary box 340.

[0064] The sludge preliminary frame 310 is equipped with several suction pumps 320. The input end of the suction pump 320 is equipped with an input pipe. The sludge preliminary frame 310 is equipped with a fastening bracket that cooperates with the input pipe. The output end of the suction pump 320 is equipped with an output pipe that communicates with the preliminary box 340.

[0065] Specifically, the floating assembly 110 allows the dredging base 100 to float on the water surface, preventing direct contact with the riverbed and maintaining the stability and buoyancy of the dredging base 100. The floating assembly 110 utilizes the floating buoy 112 to provide buoyancy, allowing the dredging base 100 to float on the water surface, while the floating support 111 provides support and stability, ensuring the smooth operation of the dredging base 100 on the water surface. The sludge dispersing assembly 200, through the design of the dispersing cylinder 210 and the sludge compression cylinder 220, disperses and compresses the sludge, making it easier to remove. The sludge dispersing assembly 200 uses mechanical force to disperse the sludge into small pieces and further compresses it through compression, thereby improving the efficiency and speed of sludge removal. The sludge suction assembly 300 uses the suction pump 320 to suck the sludge from the sludge pre-support 310 into the sludge branch pipe 330 and transport it to the sludge collection pipe 410. The sludge suction assembly 300 is responsible for pumping the broken sludge to the sludge collection unit 430 on the shore, achieving effective sludge extraction and collection, and facilitating subsequent treatment and disposal. The floating pipe support 420 undertakes important functions such as supporting, stabilizing, protecting the pipe, and adjusting the pipe position, and is a key component to ensure the smooth operation and efficient operation of the dredging system.

[0066] Furthermore, the floating pipe support 420 includes a floating base 421 set on the water surface, a support bracket 422 set on the floating base 421, a floating cylinder 423 set on the floating base 421, and a shock-absorbing circular groove 424 that cooperates with the sludge collection pipe 410 on the support bracket 422.

A plurality of shock-absorbing rope units 426 are provided between the support bracket 422 and the clamping frame 425.

[0069] Specifically, the floating pipe support 420 is designed to support the sludge collection pipe 410, ensuring its stable position on the water surface. Through a reasonable structural design and robust installation, the floating pipe support 420 can effectively bear the weight of the pipe and maintain its vertical position, preventing the pipe from tilting or swaying. The floating pipe support 420 also protects the sludge collection pipe 410. By raising the pipe above the water surface, it reduces contact between the pipe and obstacles in the water, lowering the risk of pipe damage and extending its service life. During dredging operations, it is sometimes necessary to adjust the position of the sludge collection pipe 410 for better sludge collection. The design of the floating pipe support 420 allows it to move or rotate on the water surface, thereby adjusting the pipe's position and improving the system's flexibility and adaptability. Furthermore, the design of structures such as the shock-absorbing circular groove 424 on the floating pipe support 420 further enhances the system's stability and functionality, improving the efficiency and quality of dredging operations.

The floating assembly 110 provides buoyancy through floating buoys 112, ensuring the entire system floats on the water surface; the silt dispersing assembly 200 includes a dispersing cylinder 210, a silt squeezing cylinder 220, and dispersing blades 260, etc., which disperse the silt through dispersing, squeezing, and agitation. The silt suction assembly 300 installed on the dredging base 100 is responsible for sucking the dispersed silt into the system. The suction pump 320 on the sludge preliminary support 310 pumps sludge into the preliminary tank 340 through the sludge branch pipe 330, and then filters and collects the sludge through the waste collection assembly 350. The sludge collection assembly 400 is responsible for transporting the treated sludge to the sludge collection unit 430 on the shore. The floating pipe support 420 serves to support the pipe and provide shock absorption. The support provides buoyancy through the float 423, keeping the pipe on the water surface; the shock-absorbing circular groove 424 and the shock-absorbing rope unit 426 provide shock absorption and cushioning to prevent the system from being damaged by external impacts.

[0085] Meanwhile, the traveling frame 510 incorporates a traveling assembly 520 and a stabilizing foot assembly 530. Through the horizontally arranged traveling support 521, traveling axle 522, and traveling wheels, as well as the stabilizing frame 531 and top-support hydraulic cylinder 532, the dredging base 100 can move accurately and remain stable, solving the problem of inaccurate positioning and guidance of the original equipment. The traction winch assembly 540 includes a traction frame 541, a traction winch 542, and a traction rope. The tensioning wheel assembly 550 employs a different structural design, including a tensioning frame 551, an arc-shaped frame 553, an angle shaft, and a rotating frame 554. These designs ensure that the rope is fully tensioned during operation, guaranteeing the stability and efficiency of the dredging equipment. Furthermore, a guide frame 544 and a shock-absorbing spring unit 546 are introduced. The structure of the shock-absorbing spring unit 546 is similar to that of the shock-absorbing rope unit 426. Through the design of shock-absorbing columns, shock-absorbing cylinders, and shock-absorbing ring plates, the vibration and impact experienced by the dredging base 100 are effectively reduced. Meanwhile, the guide wheel and guide bracket 233 installed on the guide frame 544, as well as the structure of the guide float plate and guide winch, ensure the accurate guidance and stability of the dredging equipment during operation.
