[0002] An axial flow pump is a pump that transports liquid along the axial direction by the force exerted by the blades of a rotating impeller on the liquid. There are several types: vertical, horizontal, oblique and cross-flow. The impeller of an axial flow pump is generally equipped with 2 to 7 blades and rotates in a tubular pump casing. Fixed guide vanes are installed on the pump casing above the impeller to eliminate the rotational motion of the liquid, converting it into axial motion and converting the kinetic energy of the rotational motion into pressure energy. The utility model is a horizontal axial flow pump.

Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0024] See also Figure 1 and Figure 2 , an embodiment provided by the utility model: a water inlet anti-blocking submersible axial flow pump;
[0025] It includes a pump body 1 and a connecting pipe 2. A connector 101 is installed at the other end of the pump body 1. A support frame 102 is symmetrically installed at the bottom of the pump body 1. A fixing plate 103 is installed at the bottom of the support frame 102. A connecting pipe 2 is installed at one end of the pump body 1. A blocking net 201 is installed at one end of the connecting pipe 2. A connecting ring 202 is opened at one end of the blocking net 201. A connecting groove 203 is opened on the front of the connecting ring 202.
[0026] The pump body 1 provides an installation position for the internal drive motor 5 so that it can be installed. The submersible axial flow pump is installed in the water flow through the fixing plate 103. The connecting pipe 2 provides a position for the installation of the blocking net 201. The blocking net 201 plays a blocking role. Foreign objects in the water flow can be blocked by the blocking net 201, and a position is also provided for the installation of the connecting rod 3.
[0027] See also Figure 1-Figure 5 , an embodiment provided by the utility model: a water inlet anti-blocking submersible axial flow pump;
[0028] It includes a connecting rod 3, a mounting net 4 and a driving motor 5. The connecting rod 3 is symmetrically installed on the inner wall of the blocking net 201, and a shaft sleeve 301 is installed at one end of the connecting rod 3. The front of the connecting rod 3 is installed with a mounting rod 302, and one end of the mounting rod 302 is installed with a mounting disk 303. The front of the mounting disk 303 is installed with a cleaning brush 304. The front of the connecting ring 202 is movably installed with the mounting net 4 through the connecting groove 203. The front of the mounting net 4 is penetrated by a connecting disk 401, and a fixed head 402 is installed on the back of the connecting disk 401. A cleaning plate 403 is symmetrically installed on the outside of the connecting disk 401, and a plurality of anti-slip hooks 404 are provided on the inside of the cleaning plate 403. The driving motor 5 is installed inside the pump body 1, and an impeller 501 is installed at the output end of the driving motor 5. A connecting shaft 502 is installed on the front of the impeller 501, and one end of the connecting shaft 502 passes through the shaft sleeve 301 and is connected to the fixed head 402;
[0029] The shaft sleeve 301 can be installed through the connecting rod 3. The shaft sleeve 301 is the outer side of the connecting shaft 502, which fixes the connecting shaft 502 and makes the connecting shaft 502 more stable when in use. The mounting rod 302 and the mounting plate 303 provide a position for the installation of the cleaning brush 304. The cleaning brush 304 contacts the mounting net 4, so that the cleaning brush 304 can clean the mounting net 4 to prevent the contaminants accumulated on the mounting net 4 during long-term use from causing blockage of the submersible axial flow pump. The mounting net 4 is movably installed on the outer side of the connecting ring 202. When the submersible axial flow pump is in use, the driving motor 5 drives the impeller 501 to rotate so that water is extracted. The connecting shaft 502 drives the mounting net 4 at one end to rotate, so that the cleaning plate 403 installed on the outer side of the mounting net 4 rotates on the outer side of the blocking net 201 to prevent the blocking net 201 from being blocked by obstacles, so that water cannot enter the submersible axial flow pump.
[0030] Working principle: Before using the water inlet anti-blocking submersible axial flow pump, you should first check whether there are any problems that affect the use of the water inlet anti-blocking submersible axial flow pump. First, fix the submersible axial flow pump to the position where it needs to be used through the fixing plate 103, and use the internal drive motor 5 to drive the impeller 501 at the output end to rotate, so as to pump out the water through the connecting head 101 and discharge it into the connected conduit. The water flow will enter the submersible axial flow pump through the blocking net 201 and the mounting net 4. The blocking net 201 and the mounting net 4 can block foreign objects in the water flow to prevent them from entering the interior of the submersible axial flow pump and causing damage to the internal structure.
[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description.
