[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] Reference Figure 1-5 The utility model embodiment is a submersible sewage pump sand prevention structure, which includes a protective ring 1 and a storage ring 7. A conical sand prevention net 2 is arranged on the peripheral surface of the outer end of the protective ring 1, a first connecting ring 3 is arranged on the inner side of the protective ring 1, and limiting slots 6 are arranged on the inner side of the outer end of the first connecting ring 3. A filter net 8 is arranged on the inner side of the storage ring 7, and positioning blocks 9 are arranged on the peripheral surfaces of the outer side of the storage ring 7. A support ring 4 is arranged on the middle part of the inner side of the protective ring 1, and a second connecting ring 5 is arranged around the inner side of the support ring 4.

[0025] The conical sand-proof net 2 is made of stainless steel wire, and the conical sand-proof net 2 is fixedly welded to the peripheral surface of the outer end of the protective ring 1. The protective ring 1 and the first connecting ring 3 are both made of stainless steel. The first connecting ring 3 is fixedly connected to the inner side of the protective ring 1 through threads, and four limiting slots 6 are provided. The four limiting slots 6 are all recessed and connected with the inner sides of the outer end of the first connecting ring 3. The limiting slots 6 are provided to provide a positioning and locking effect for the installation of the filter net 8 and the inner side of the first connecting ring 3, and prevent the placement ring 7 from rotating or shifting. The filter net 8 is fixedly supported and connected to the inner side of the placement ring 7, and the filter net 8 forms an open support effect through the inner side of the placement ring 7, so as to position the filter net 8. Four clamping blocks 9 are provided, and the four positioning clamping blocks 9 are all fixedly contacted and connected with the outer peripheral surfaces of the storage ring 7. The storage ring 7 forms a positioning support connection with the inside of the first connecting ring 3 through the clamping connection between the positioning clamping blocks 9 and the limiting clamping grooves 6. The support ring 4 is fixedly contacted and connected with the middle part of the inner side of the protective ring 1. The second connecting ring 5 is fixedly contacted and connected with the inner periphery of the support ring 4. The inner wall of the space formed between the first connecting ring 3 and the second connecting ring 5 is threadedly sealed and connected with the outer side around the inlet of the submersible sewage pump. The second connecting ring 5 is provided to provide a sealing effect when the first connecting ring 3 and the protective ring 1 are threadedly sealed and connected with the outer side around the inlet of the submersible sewage pump.

[0026] Working principle: The protective ring 1 and the first connecting ring 3 made of stainless steel are used. The stainless steel material with high hardness and wear resistance can effectively reduce the impact and wear of solid particles on the submersible sewage pump components. The conical sand-proof net 2 and the filter net 8 are installed at the inlet and outlet of the submersible sewage pump, which can effectively prevent larger particles of solid from entering the submersible sewage pump and reduce the wear on the submersible sewage pump. The conical sand-proof net 2 is generally welded with stainless steel wire, which has certain strength and wear resistance. At the later stage, the conical sand-proof net 2 can be separated from the outer side of the first connecting ring 3 through the protective ring 1 by threaded connection, which is convenient for cleaning the conical sand-proof net 2. At the same time, the filter net 8 can be separated from the inner side of the first connecting ring 3 through the placement ring 7 and the positioning block 9, which is convenient for replacing and cleaning the filter net 8, thereby improving the practical efficiency of the sand-proof structure of the submersible sewage pump.
