Description

Technical Field

[0001] The utility model relates to the technical field of submersible pumps, and in particular to a stable submersible pump. Background Art

[0002] Submersible pumps are important equipment for underground water extraction. When in use, the entire unit dives into the water to extract groundwater to the surface. Usually, traditional submersible pumps are placed directly on the bottom of the water, which not only easily causes the submersible pump to tip over and make it unable to work stably, but also easily absorbs impurities such as mud and sand on the bottom of the water, which brings certain troubles to the use of the submersible pump.

[0003] In this regard, China Patent Publication No. CN212838317U discloses "a stable submersible pump, which is provided with a fixing ring on the submersible pump body, inserts the threaded rod on the mounting ring into the through hole on the fixing ring, and fixes the mounting ring with a locking bolt, which can facilitate the disassembly and installation of the mounting ring, and is convenient for people to carry. After being fixed, the supporting legs can support the submersible pump body. By providing an annular filter screen on the first connecting ring and the second connecting ring, the water drawn into the submersible pump during operation can be filtered to prevent large particles of impurities from entering and clogging the submersible pump."

[0004] The above patent filters the water drawn into the submersible pump when it is working through a filter screen. After filtering, a large amount of impurities will be adsorbed on the filter screen. As the impurities accumulate, the filter holes of the filter screen are easily blocked, which will affect the water intake of the submersible pump. In addition, the upper part of the submersible pump lacks a supporting structure, and only relies on the supporting legs at the bottom to be inserted into the bottom of the water to cooperate with the overall deadweight to place the submersible pump. The stability of the submersible pump is bound to be poor. In view of this, the utility model proposes a stable submersible pump. Utility Model Content
