However, when the submersible pump is sucking water, there are many impurities in the underwater environment of the placed water area, so that the water sucked through the water inlet contains waterweeds, which will cause the waterweeds to entangle on the suction disc, resulting in the suction disc being unable to rotate for water suction. When the submersible pump is put into water and taken out of water, it is usually slowly put into water by pulling the power cord. Long-term pulling of the power cord will cause the power cord to be damaged, resulting in water ingress and electric leakage. Summary of the Utility Model

Specific implementation manner

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides a submersible pump as shown in Figures 1-5 that can achieve dual-switch control, including a pump head 1 and a pump cover 2 and a pump body 3 below the pump head 1;

[0028] The upper end of the pump cover 2 is fixedly connected to a water outlet 12;

[0029] The lower end of the pump body 3 is sleeved upward with a pump bottom 5;

[0030] The upper end of the pump cover 2 is fixedly connected to a cable b 11, the other end of the cable b 11 is fixedly connected to a controller 10, and the lower end of the controller 10 and near the left and right sides are respectively fixedly connected to a cable a 9. The other ends of the two cables a 9 are respectively provided with a plug 7 and a float switch 8, and a plurality of water inlets 14 are equidistantly arranged on the outer wall of the pump bottom 5;

[0031] The outer thread of the pump bottom 5 is connected with a fixing ring 6. The lower end of the fixing ring 6 is fixedly connected with a filter screen a15. The lower end of the fixing ring 6 and inside the filter screen a15 is fixedly connected with a filter screen b17. A threaded block 18 is threadedly connected between the filter screen a15 and the filter screen b17;

[0032] Among them, rotating the filter screen a15 counterclockwise can screw the filter screen a15 off the filter screen b17, and rotating the fixing ring 6 counterclockwise can screw the fixing ring 6 off the pump bottom 5. The lower end of the filter screen a15 is fixedly connected with a bottom plate 16. The mesh density of the filter screen a15 is greater than that of the filter screen b17. The filter screen a15 and the bottom plate 16 are fixedly connected by welding. Both the filter screen a15 and the filter screen b17 are made of stainless steel. The upper end of the pump head 1 is rotatably connected with a handle 13. An absorbing disc is arranged inside the pump bottom 5. The plug 7 is electrically connected to an external power supply. The float switch 8 floats on the water, which is convenient for detecting the water level through the float switch 8 and performing switch operations through the controller 10. First, connect the water outlet 12 and an external water delivery pipe, and then connect the plug 7 and the external power supply for power supply. When the submersible pump is completely immersed in the water area, the drive motor inside the pump body 3 controls the absorbing disc to suck the water in the water area through the water inlet 14 on the pump bottom 5, and the sucked water will be discharged through the pipe connected to the water outlet 12. If the float switch 8 is forced to open, the submersible pump is forced to be powered on. On the contrary, when the float switch 8 is disconnected, the submersible pump is controlled by an internal pressure switch. Before the water in the water area enters through the water inlet 14, it will be first blocked by the filter screen a15, blocking the waterweeds and other sundries in the water. The sundries that cannot be blocked by the filter screen a15 will enter through the filter screen a15 and be secondarily blocked by the filter screen b17, and the sundries will be restricted in the gap between the filter screen a15 and the filter screen b17. After the submersible pump finishes working, the filter screen a15 and the fixing ring 6 can be removed from the filter screen b17 and the pump bottom 5 respectively by rotating them counterclockwise for cleaning, and they can be reinstalled after cleaning to continue using.

[0033] Such as Figure 5As shown in the figure, limit rings 4 are fixedly connected to the circular outer wall of the pump body 3 near the upper and lower sides respectively. An extension rope 21 wound around the pump body 3 is arranged between the two limit rings 4. A fixing block 20 is fixedly connected to the circular outer wall at the left end of the pump body 3 and above the limit ring 4. A fixing hole 19 penetrating through the front and back is arranged inside the fixing block 20. The extension rope 21 is woven from nylon material, has high toughness and will not break easily. The extension rope 21 can penetrate into the inside of the fixing hole 19. When the submersible pump needs to be put into the water area, the extension rope 21 can be removed, one end of the extension rope 21 is inserted into the inside of the fixing hole 19 and tied to the fixing block 20 for fixation. Then, the submersible pump can be put into the water area by dragging the extension rope 21, and the other end of the extension rope 21 is fixed to prevent the extension rope 21 from sinking into the water area. After the submersible pump finishes working, the submersible pump can be pulled out by dragging the other end of the extension rope 21. After pulling out, the extension rope 21 is wound around the limit rings 4 again.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
