Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to an anti-blocking pump device. Background Art

[0002] Water seepage may occur during the excavation of the foundation pit. To ensure the safety of the foundation pit construction, effective precipitation and drainage measures must be taken. The large amount of silt in the foundation pit can easily clog the filter holes on the sewage pump. To avoid clogging of the filter holes, the existing technology (such as the utility model patent with application number 202320955250.5) will set a separate impeller in the sewage pump. The impeller drives the scraper to rotate, and the water flow drives the impeller to rotate, so that the scraper can scrape off the blockage on the filter screen.

[0003] The sewage pump of the above structure has the problem that after the filter hole is blocked, the water intake and flow rate of the sewage pump are reduced, which directly leads to a reduction in the impeller speed, causing the scraper to lose power to scrape the blockage on the filter screen.

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 As shown, this embodiment discloses an anti-blocking pump device, including a counterweight base 1, a scraper ring 2, a support rod 3 and a shield 4. The scraper ring 2 is arranged above the counterweight base 1, and support rods 3 are arranged on both sides of the scraper ring 2. The support rods 3 are connected to the scraper ring 2, and the lower ends of the support rods 3 are fixed to the counterweight base 1. The shield 4 is arranged on the pump body 5, and a plurality of filter holes 6 are arranged on the outer wall of the shield 4. The shield 4 is nested with each scraper ring 2.

[0019] During use, when the displacement of the pump body 5 is significantly reduced, the traction rope on the pump body 5 is pulled by the traction device, so that the pump body 5 and the protective cover 4 are lifted as a whole. During the lifting process of the protective cover 4, the scraper ring 2 will scrape off the blockage on the filter hole 6 on the outer wall of the protective cover 4.

[0020] In order to prevent the shield 4 from being separated from the scraper ring 2 during the lifting process of the pump body 5, in this embodiment, a limit pull rope 7 is arranged below the shield 4, one end of the limit pull rope 7 is connected to the shield 4, and the other end is connected to the counterweight base 1.

[0021] In this embodiment, the shield 4 includes a shield body 401 and a cover 402. The cover 402 can be welded to the pump body 5. The shield body 401 and the cover 402 are connected by a bolt assembly. One end of the limit pull rope 7 is fixed to the shield body 401.

[0022] In this embodiment, a lifting ring 8 is provided on the counterweight base 1. The lifting ring 8 is connected to a safety rope to prevent the counterweight base 1 from being lost.

[0023] In this embodiment, the edge of the top surface of the counterweight base 1 is inclined outward.

[0024] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
