[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1 - Figure 2 , a floating boat pump for preventing blockage disclosed in the embodiment of the present invention, including a body 1, the body 1 includes a floating bucket 11 and a water pump 12. An inlet is opened at the center of the bottom of the floating bucket 11. The input end of the water pump 12 is arranged at the inlet. The output shaft of the water pump 12 is coaxial with the inlet. A plugging prevention cylinder 2 is detachably installed at the inlet. A filter screen 21 is arranged at one end of the plugging prevention cylinder 2 away from the inlet. A rotating column 31 is rotatably installed in the plugging prevention cylinder 2. A spline hole is opened on the output shaft of the water pump 12. One end of the rotating column 31 away from the filter screen 21 is set as a spline end. After the plugging prevention cylinder 2 is installed, the rotating column 31 is inserted into the output shaft of the water pump 12. A plurality of slitting blades 32 are fixedly installed on the rotating column 31. The plurality of slitting blades 32 are arranged in an axial array along the rotating column 31. A blocking rod 33 is installed on the side wall of the plugging prevention cylinder 2. The blocking rods 33 are installed in a circumferential array along the side wall of the plugging prevention cylinder 2. A group of blocking rod 33 arrays are arranged on both sides of the slitting blade 32.

[0032] Specifically, a plugging prevention cylinder 2 is arranged at the inlet at the center of the bottom of the floating bucket 11. A filter screen 21 for blocking sundries is arranged at one end of the plugging prevention cylinder 2 away from the inlet. A slitting blade 32 and a blocking rod 33 are arranged inside the plugging prevention cylinder 2. The blocking rods 33 form a multi-layer circumferential array of blocking rods 33 in the plugging prevention cylinder 2 to block long strip-shaped objects entering the plugging prevention cylinder 2. The slitting blade 32 is arranged between adjacent circumferential arrays of blocking rods 33 to cut the sundries so that the sundries are mixed into the water flow and ejected.

[0033] In this way, through the blocking effect of the blocking rod 33 array and the cutting effect of the slitting blade 32, some strip-shaped sundries that are easily wound around the impeller shaft are chopped up and then carried away by the water flow and ejected, reducing the possibility that the impeller shaft is wound by them and is not easy to clean, affecting the normal operation of the impeller.

[0034] In some feasible ways, the main body 1 is a commonly used floating pump, the anti-clogging cylinder 2 is cylindrical, and is installed at the water inlet position by means of clamping, threaded connection or bolt connection. The rotating column 31 is a cylinder coaxial with the anti-clogging cylinder 2, and the rotating column 31 is key-connected to the impeller shaft. When the impeller shaft rotates, it drives the rotating column 31 to rotate, and then drives the cutting edge 32 to rotate. The blocking rod 33 is a columnar rod arranged radially along the anti-clogging cylinder 2. After the strip-shaped object enters and is blocked by the blocking rod 33, the cutting edge 32 cooperates to cut, so that its length cannot form a winding around the impeller shaft.

[0035] In some feasible ways, to improve the blocking effect of the blocking rod 33, the blocking rods 33 arranged in an annular array are staggered, and barbs are provided on the side of the blocking rod 33 close to the filter screen 21.

[0036] As a specific implementation of an anti-clogging floating pump provided by the application, the filter screen 21 is hemispherical, and the filter screen 21 protrudes from the bottom surface of the floating barrel 11.

[0037] Overall, in a location with a complex environment, there are various sundries in the water. By setting the filter screen 21 as a hemispherical shape protruding from the bottom surface of the floating barrel 11, the possibility of some plate-shaped sundries being adsorbed at the water inlet position and blocking the water inlet is reduced. Through the spherical setting, the contact area between the sundries and the filter screen 21 is reduced, thereby reducing blockage.

[0038] In some feasible ways, the filter screen 21 is threadedly connected to the anti-clogging cylinder 2 for easy disassembly and cleaning of the filter screen 21.

[0039] As another specific implementation of an anti-clogging floating pump provided by the application, a discharge cylinder groove 41 is provided at the bottom of the floating barrel 11 near the water inlet position. A discharge cylinder rod 42 is slidably installed in the discharge cylinder groove 41. An installation hole is provided on the side wall of the anti-clogging cylinder 2. During installation, the discharge cylinder rod 42 slides and inserts into the installation hole, and a return spring 43 is provided between the discharge cylinder rod 42 and the discharge cylinder groove 41.

[0040] Combined with the specific usage scenario, please refer to Figure 3 , by setting the part of the discharge cylinder rod 42, it is convenient to disassemble the anti-clogging cylinder 2 for cleaning and maintenance of the anti-clogging cylinder 2.

[0041] In some feasible ways, the discharge cylinder groove 41 is in the shape of a rectangular groove, the discharge cylinder groove 41 penetrates to the water inlet, and a rectangular plate is fixedly installed on the side of the discharge cylinder groove 41 facing the water inlet. The discharge cylinder rod 42 is slidably installed on the rectangular plate.

[0042] As a specific implementation of an anti-clogging floating pump provided by the application, please refer to Figure 1 , two water outlet pipes 5 are installed on the side of the floating barrel 11. The water outlet pipes 5 are connected to the output end of the water pump 12, and the water outlet pipes 5 are connected with electromagnetic valves.

[0043] It should be understood that by providing the water outlet pipe 5, with the water outlet pipe 5 provided on both sides of one side of the floating bucket 11, when the solenoid valve is opened, liquid sprays out from the water outlet pipe 5, and the reaction force of the liquid causes the floating bucket 11 to move, facilitating the floating bucket 11 to move away from the area where debris accumulates and move to a position convenient for water absorption.

[0044] In some feasible ways, the water outlet pipe 5 is provided on the side where the output end of the water pump 12 is located, and two water outlet pipes 5 are provided on both sides of the output end of the water pump 12. Usually, a water pipe is installed at the output end of the water pump 12. By installing the water outlet pipe 5 on this side, the water pipe and the water outlet pipe 5 are in the same direction as the direction of the reaction force, reducing the influence of the water pipe on the driving of the floating boat pump by the water outlet pipe 5. The solenoid valve is electrically connected to the power supply and the controller of the floating boat pump, and the floating boat pump is a remotely controllable floating boat pump.

[0045] 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 within the protection scope of the present invention.
