Description

Technical Field

[0001] This utility model relates to the field of civil engineering and water conservancy construction equipment, specifically to a dredging device for civil engineering and water conservancy construction. Background Technology

[0002] Dredging equipment for civil engineering and water conservancy construction is a type of machinery used to remove silt, sediment, and debris from water bodies such as rivers, reservoirs, canals, and pipelines. It is widely used in water conservancy projects, municipal construction, and environmental protection. River dredging vessels are common dredging equipment. They use high-pressure water jets or cutterheads to agitate sediment at the bottom of the river, breaking down hardened silt into a suspended state. Then, a sludge pump generates negative pressure, drawing the sludge-water mixture into the pump body through a suction pipe, thus cleaning the silt. Although protective devices exist to prevent plastic bags, stones, and sticks from entering the sludge pump, these items still adhere to the protective devices in actual use, preventing the pump from effectively removing silt from the bottom. Summary of the Invention

[0004] A dredging device for civil engineering and water conservancy construction includes a dredging device body, which includes a sludge pump.

[0018] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0019] like Figure 1-2As shown, this embodiment provides a dredging device for civil engineering and water conservancy construction, including a dredging device body 100, which includes a sludge pump 100, and a hook 160 at the sludge pump 100. An installation plate 120 for sealing the inlet of the sludge pump 110 is provided at the inlet, with an inlet hole 210 and a partition net 130. The partition net 130 includes a housing 131 connected to the installation plate 120, with filter screens 132 at both ends of the housing 131. A rotating rod 220 is rotatably mounted in the partition net 130, and a scraper 230 for scraping away the deposits at the inlet hole 210 is provided at the rotating rod 220. The end of the rotating rod 220 extends out of the partition net 130, and a mounting base 140 is provided at the end of the rotating rod 220 extending out of the partition net 130. Multiple scraper blades 150 are provided at the mounting base 140.

[0020] In use, the dredging device for civil engineering and water conservancy construction is placed on a dredging vessel and transported to the dredging site. Once the site is reached, the dredging device body 100 is placed in the water by ropes tied to the hook 160. The rotating rod 220 is driven to rotate and the power supply to the sludge pump 110 is turned on. The scraper 150 scrapes the sludge at the bottom of the water. The negative pressure of the sludge pump 110 pumps the scraped sludge to the dredging vessel for processing. The aperture of the partition 130 is larger than that of the inlet hole 210. The partition 130 is used to separate larger stones and sticks from the scraper 230, so as to prevent the scraper 230 from colliding with and being damaged by the larger stones and sticks. The suction of the sludge pump is also insufficient to suck in the larger stones and sticks. When smaller stones, plastic bags, sticks, etc. enter the partition 130 through the partition 130, they will be attracted to the inlet hole 210 by the suction of the sludge pump 110. The rotating scraper 230 can scrape them off to avoid clogging of the inlet hole 210.

[0021] The dredging device for civil engineering and water conservancy construction in this embodiment, through the setting of the partition net 130 and the scraper 230, can not only prevent small stones, plastic bags and wooden sticks from entering the sludge pump 110 and causing damage to the sludge pump 110 during dredging operations, thus better protecting the sludge pump 110; it also avoids the blockage of the water inlet hole 210, thereby better improving the working efficiency of the sludge pump 110.

[0022] In this embodiment, the outer shell 131 is provided with an outer shell through hole 240 that is clearance-fitted with the rotating rod 220, and the outer shell 131 is provided with a mounting cylinder 250 located at the outer shell through hole 240, and the rotating rod 220 is disposed in the mounting cylinder 250.

[0023] The mounting cylinder 250 at the outer casing 131 enables the installation of the rotating rod 220, allowing the rotating rod 220 to rotate within the mesh 130.

[0024] Combination Figure 3 As shown, a driven gear 310 is also provided at the rotating rod 220, a motor mounting cavity 260 is provided in the outer shell 131, a drive motor 320 is provided in the motor mounting cavity 260, and a driving gear 330 that meshes with the driven gear 310 is provided at the rotating shaft of the drive motor 320.

[0025] The rotation rod 220 can be driven by the meshing of the driving gear 330 at the drive motor 260 and the driven gear 310 at the rotating rod 220. It should be noted that, to improve the stability of the drive motor 320 during operation, the drive motor 320 in this embodiment is a waterproof motor.

[0026] Furthermore, a sealing cover 270 is provided in the outer casing 131, and a sealed cavity 280 is formed between the sealing cover 270 and the outer casing 131; the drive motor 320, the driving gear 330 and the driven gear 310 are all disposed in the sealed cavity 280.

[0027] The sealed cavity 280 formed between the sealing cover 270 and the outer shell 131 not only further protects the drive motor 320, but also prevents stones, plastic bags, wooden sticks, etc. that enter the mesh 130 from getting stuck at the drive gear 330 and the driven gear 310, thereby further improving the stability of the dredging device for civil engineering and water conservancy construction during use.

[0028] Furthermore, the outer casing 131 is provided with a motor mounting cavity opening 340 communicating with the motor mounting cavity 260, a cover plate 350 is provided at the motor mounting cavity opening 340, and a cover plate through hole 360 ​​is provided at the cover plate 350 for the cable of the drive motor 320 to pass through.

[0029] The cover plate 350 facilitates the installation of the drive motor 320, and the through hole 360 ​​in the cover plate facilitates the routing of the drive motor 320 cable.

[0030] The specific working process of the dredging device for civil engineering and water conservancy construction in this embodiment is as follows:

[0031] In use, the dredging device for civil engineering and water conservancy construction is placed on a dredging vessel and transported to the dredging site. Once the site is reached, the dredging device body 100 is placed in the water by ropes tied to the hook 160. The power supply of the drive motor 320 is turned on to drive the rotating rod 220 to rotate and the power supply of the sludge pump 110 is turned on. The scraper 150 scrapes the sludge at the bottom of the water. The negative pressure of the sludge pump 110 causes the scraped sludge to be pumped into the dredging vessel for treatment through the partition net 130, the water inlet 210 and the sludge pump 110.

[0032] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
