Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps, relates to a submersible pump, and particularly relates to a new type of submersible pump. Background Art

[0002] At present, a filter screen is usually sleeved at the end of the submersible pumps on the market. The filter screen is generally integrated and is very difficult to remove after being sleeved on the submersible pump. Therefore, the inner ring position of the filter screen is not easy to disassemble and clean, resulting in excessive impurities remaining in the gap of the inner ring of the filter screen, affecting the use. Summary of the Invention

[0003] The purpose of the utility model is to provide a new type of submersible pump with a filter screen that is convenient to clean for the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A new type of submersible pump, including a pump body, characterized in that a connecting disc with a radially outward expansion is provided on the peripheral wall at the bottom of the pump body, and a filter screen assembly arranged in two halves is fixed at the bottom of the connecting disc. The filter screen assembly is composed of a filter screen one and a filter screen two. Both the filter screen one and the filter screen two are semi-ring structures. Limiting protrusions protruding outward are provided at both ends of the filter screen one. Access grooves for positioning and accessing the limiting protrusions are provided at both ends of the filter screen two. Both the inner and outer circles of the limiting protrusion are arc surface structures, and the limiting protrusion inserted into the access groove is connected to the filter screen two by screws.

[0005] In the above-mentioned new type of submersible pump, two connecting extension plates radially extending outward from the outer circles at the tops of the filter screen one and the filter screen two are provided at the top of the filter screen assembly, and the two connecting extension plates are connected to the connecting disc by fixing screws.

[0006] Compared with the prior art, the new type of submersible pump has the advantage of being convenient for cleaning the filter screen. Brief Description of the Drawings

[0010] The following are specific embodiments of the utility model in combination with the drawings to further describe the technical solutions of the utility model, but the utility model is not limited to these embodiments.

[0011] Such as Figure 1 、 Figure 2As shown in the figure, the present new submersible pump includes a pump body 1. The circumferential wall at the bottom of the pump body 1 has a radially outwardly expanding connecting plate 2. A filter screen assembly arranged in two halves is fixed to the bottom of the connecting plate 2. The filter screen assembly is composed of a first filter screen 3 and a second filter screen 4. Both the first filter screen 3 and the second filter screen 4 are semi-ring structures. The two ends of the first filter screen 3 have outwardly protruding limit protrusions 5. The two ends of the second filter screen 4 are provided with access grooves for positioning and accessing the limit protrusions 5. The inner and outer circles of the limit protrusions 5 are both arc surface structures. The limit protrusions 5 inserted into the access grooves are connected to the second filter screen 4 by screws, resulting in the fixed connection of the first filter screen 3 and the second filter screen 4.

[0012] The top of the filter screen assembly has two connecting extension plates 6 radially extending outward from the outer circles at the tops of the first filter screen 3 and the second filter screen 4. The two connecting extension plates 6 are connected to the connecting plate 2 by fixing screws, achieving the fixation of the filter screen assembly to the submersible pump.

[0013] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0014] Although terms such as pump body 1, connecting plate 2, first filter screen 3, second filter screen 4, limit protrusion 5, connecting extension plate 6, etc. are used more frequently herein, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
