A raised seat is provided at the lower end of the pump body, and the raised seat is staggered with the water inlet. The pump body is also provided with a filter plate, and the filter plate is evenly distributed with a plurality of through holes. The filter plate is located at the water inlet for filtering the liquid passing through the water inlet. The end face of the impeller close to the water inlet is coaxially provided with a rotating shaft, and the filter plate is provided with a rotating hole. The rotating shaft penetrates the filter plate through the rotating hole and is rotatably connected with the filter plate. The rotating shaft is provided with a cutting blade, and the cutting blade is located on the side of the filter plate away from the pump cavity. The cutting blade contacts the filter plate, and the cutting blade cooperates with the hole wall of the through hole to cut debris. The submersible pump can only handle debris sucked into the raised seat. Large debris may directly block the raised seat, causing the submersible pump to be blocked. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide an underwater filtering submersible pump to solve the problem that the existing submersible pumps are not easy to handle large debris.

[0005] Based on the above purpose, the present invention provides an underwater filtering submersible pump, including a base frame, a water pump body, a flange, a first filter frame, a second filter frame, an annular net, a plurality of columns, an air bag and an air supply part, wherein:

[0034] like Figures 1 to 5 As shown, an underwater filtering submersible pump includes a base frame 1, a water pump body 2, a flange 3, a first filter frame 4, a second filter frame 5, an annular net 6, a plurality of columns 7, an air bag 8 and an air supply part, wherein:

[0035] The first filter frame 4 is arranged on the top of the base frame 1, a top cover is arranged on the top of the first filter frame 4, and a bracket 9 is arranged inside the first filter frame 4;

[0036] The flange 3 is fixedly arranged on the water pump body 2.

[0037] The water pump body 2 is disposed in the first filter frame 4 and is mounted on the bracket 9 through the flange 3;

[0038] The second filter frame 5 is movably sleeved on the first filter frame 4;

[0039] The annular network 6 is arranged at the lower end of the second filter frame 5;

[0040] A plurality of the upright posts 7 are distributed in an annular manner on the annular net 6;

[0041] The airbag 8 is arranged at the bottom of the annular net 6;

[0042] The air supply part is used to inflate or deflate the airbag 8;

[0043] The second filter frame 5 can block small and large debris, and the air supply part supplies air to the airbag 8 so that the second filter frame 5 floats on the water surface, making it easy to clean the debris on the second filter frame 5.

[0044] When the submersible pump is working, the submersible pump is installed in the first filter frame 4, and the second filter frame 5 is sleeved on the outside of the first filter frame 4. When the submersible pump starts to pump water, large or small debris can be blocked by the second filter frame 5. After a period of time, the air bag 8 is inflated through the air supply part to make the air bag 8 generate a larger buoyancy, and then push the second filter frame 5 to float up to the surface of the water. Then, the second filter frame 5 is manually pulled to the shore to clean up the debris on the second filter frame 5. After cleaning, the second filter frame 5 is moved to the top of the first filter frame 4, and the air bag 8 is controlled to deflate. The second filter frame 5 sinks and is sleeved on the first filter frame 4. When the second filter frame 5 is cleaned, a short filtration is performed through the first filter frame 4.

[0045] From the above, it can be seen that in the present invention, large or small debris can be blocked by the second filter frame 5 and then cleaned, thereby realizing the function of filtering and cleaning large debris. At the same time, the entire submersible pump body 2 is covered by the first filter net to prevent debris from being adsorbed on the filter pump body and affecting the heat dissipation of the filter pump body.

[0046] In some embodiments, the submersible pump includes a cutting part, which is used to cut large debris. Large debris easily causes all small debris around the large debris to be adsorbed onto the large debris, thereby causing large-area debris accumulation. In order to solve this problem, the present invention designs a cutting part.

[0047] Optionally, the cutting portion includes a rotating shaft 10 arranged between two adjacent columns 7, and a plurality of cutting knives 11 are distributed in a ring on the rotating shaft 10, the cutting knives 11 on the lower side are close to the water suction port of the water pump body 2, and the cutting knives 11 on the upper side are far away from the water suction port of the water pump body 2.

[0048] Since the cutting knife 11 on the lower side is close to the water suction port of the water pump body 2, and the cutting knife 11 on the upper side is far away from the water suction port of the water pump body 2, when the water pump body 2 absorbs water, the water flow will generate a force on the cutting knife 11. The force applied to the cutting knife 11 close to the water suction port of the water pump body 2 is greater than the force applied to the cutting knife 11 far away, so the cutting knife 11 will be driven to rotate to cut some large debris, turning the large debris into small debris, which is not easy to attract other surrounding debris.

[0049] In some embodiments, the submersible pump includes a reminder unit, which is used to remind people to clean the second filter frame 5 at regular intervals.

[0050] Optionally, the reminder unit includes a timer, a controller, a signal transmitter and a signal receiver, the timer is used to set the reminder time interval, when the time is reached, the controller controls the signal transmitter to send a signal, and the signal receiver receives the signal to remind people. Optionally, the signal receiver is a mobile phone.

[0051] The reminder time interval is set by the timer, for example, the time interval is 40 minutes. When 40 minutes are reached, the controller obtains the signal control signal transmitter to send a signal to the mobile phone. Specifically, the corresponding APP can be installed in the mobile phone to remind through the APP. The method of reminding through the APP is a prior art and will not be described in detail here.

[0052] As can be seen from the above, the reminder unit can be used to regularly remind people to clean the second filter frame 5 to avoid excessive debris on the second filter frame 5 that affects the pumping effect.

[0053] In some embodiments, the base frame 1 includes two first bottom plates 12 and a plurality of second bottom plates 13, and the plurality of second bottom plates 13 are evenly distributed between the two first bottom plates 12. There is a gap between two adjacent second bottom plates 13, so that the base frame 1 can be made lighter and easier to sink to the bottom of the water.

[0054] In some embodiments, the air supply unit includes an air pipe 14 , one end of which is connected to the airbag 8 , and the other end of which is provided with an air pump 15 . The air pipe 14 is provided with a branch pipe 16 , and the branch pipe 16 is serially connected with a valve 17 .

[0055] When it is time to inflate, the valve 17 is closed, and air is inflated into the airbag 8 through the air pump 15. When it is time to deflate, the valve 17 is opened, and the gas in the airbag 8 is released through the trachea 14 and the branch pipe 16.

[0056] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

[0057] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
