[0035] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0036] Please refer to the following: Figures 1 to 8 This application describes a floating pump. The floating pump includes a floating base 1, a filter screen 2, and a cleaning assembly 3. The top of the floating base 1 has a mounting groove 11 for mounting the pump body and engine. The bottom wall of the mounting groove 11 has a mounting hole 12, within which the pump body is located. The filter screen 2 is installed at the bottom of the floating base 1 at the mounting hole 12, with the pump body's inlet facing the filter screen 2. One end of the cleaning assembly 3 is hinged to the bottom of the floating base 1. The cleaning assembly 3 is rotatable about the hinge axis to remove debris from the filter screen 2. The hinged end of the cleaning assembly 3 has a rotating shaft 31 passing through the floating base 1, with the protruding end of the rotating shaft 31 located in the mounting groove 11. The mounting groove 11 contains a drive structure for driving the rotating shaft 31 to rotate. The pump body and engine are prior art and will not be described in detail here.

[0037] The floating pump provided in this application, compared with the prior art, has a filter screen 2 at the bottom of the floating body base 1 that can filter the water entering the pump body, reducing the amount of debris entering the pump body and thus reducing the impact of debris on the pump body during operation; during the pumping process, if debris such as leaves sticks to the surface of the filter screen 2, the cleaning component 3 rotates around the hinge axis to clean the debris such as leaves on the filter screen 2, reducing the amount of debris attached to the filter screen 2; with the above settings, the debris such as leaves on the filter screen 2 can be cleaned without taking the floating body base 1 out of the water.

[0038] It should be noted that the position where the floating base 1 passes through the pivot 31 is not hollow, so there is no situation where water enters the interior of the floating base 1 from the pivot 31 position.

[0039] In some embodiments, such as Figures 1 to 8 As shown, the cleaning assembly 3 includes a swing arm 32 and a brush 33, with the brush 33 fixed to the top of the swing arm 32; a rotating shaft 31 is installed at one end of the swing arm 32.

[0040] It should be noted that the cleaning component 3 does not need to work continuously. It can be started at regular intervals to clean the debris on the filter screen 2. During the rotation of the swing arm 32 around the rotating shaft 31, the brush 33 can cover the filter screen 2 to the maximum extent, and the brush 33 is in close contact with the filter screen 2, which facilitates the cleaning of the debris on the filter screen 2.

[0041] In some embodiments, such as Figures 1 to 8As shown, the bottom of the floating base 1 has two L-shaped plates 13, which are located at both ends of the movement path of the swing rod 32 to limit the swing position of the swing rod 32. The rotation range of the swing rod 32 does not exceed the side of the floating base 1. When the swing rod 32 swings to the L-shaped plate 13, the L-shaped plate 13 provides support for the swing rod 32, and the swing rod 32 is in a position away from the filter screen 2, so as not to affect the normal operation of the filter screen 2.

[0042] The two L-shaped plates 13 are located at the two ends of the movement path of the swing arm 32, respectively, which can provide a limit for the swing arm 32, prevent the swing arm 32 from swinging excessively, and ensure that the swing arm 32 always moves within the predetermined range.

[0043] When the swing arm 32 moves to the position of the L-shaped plate 13, this is the position where the swing arm 32 stops working. The L-shaped plate 13 can support the swing arm 32, thus facilitating the stability of the swing arm 32.

[0044] In some embodiments, such as Figures 1 to 8 As shown, the bottom of the float base 1 is connected to L-shaped slides 14 on both sides of the mounting hole 12, and the two sides of the filter screen 2 are slidably engaged with the two L-shaped slides 14 respectively; wherein, the top of the swing rod 32 can contact the bottom of the L-shaped slide 14.

[0045] The filter screen 2 slides with two L-shaped slides 14, which facilitates the disassembly and assembly of the filter screen 2 and makes it easy to replace the filter screen 2 if it is damaged.

[0046] After the filter screen 2 slides into place, the two L-shaped slides 14 can provide support for the filter screen 2, improving the stability and reliability of the filter screen 2; the filter screen 2 is a corrosion-resistant filter screen, the flow area of ​​the filter screen does not affect the performance of the pump body, and the filter screen holes can only pass through particles ≤8mm.

[0047] In some embodiments, such as Figures 1 to 8 As shown, one end of the L-shaped slide 14 is slidably engaged with the filter screen 2, and the other end of the L-shaped slide 14 has a limiting plate 15 to limit the sliding position of the filter screen 2.

[0048] By setting a limiting plate 15 on the L-shaped slide 14, the installation position of the filter screen 2 can be restricted, so that the filter screen 2 covers the mounting hole 12 at the bottom of the float base 1; on the other hand, during normal use, the situation where the filter screen 2 falls out of the L-shaped slide 14 can be reduced.

[0049] In some embodiments, such as Figures 1 to 8As shown, the bottom of the float base 1 has a placement groove 16 for placing the pump body outlet pipe. One end of the placement groove 16 is connected to one side of the float base 1, and the other end of the placement groove 16 is connected to the mounting hole 12. The filter screen 2 has a sealing plate 21, and the sealing plate 21 has a bent end 22 that contacts the side of the float base 1. The bent end 22 has a through hole for the outlet pipe to pass through. The sealing plate 21 can seal the bottom of the placement groove 16.

[0050] By setting a placement groove 16 in the float base 1, during the pump installation process, the pump body is placed into the mounting hole 12 at the bottom of the float base 1, at which time the water outlet pipe on the pump body is located in the placement groove 16; then the engine is placed in the mounting groove 11 and the engine is connected to the pump body; finally, the engine is fixed in the mounting groove 11.

[0051] By setting a sealing plate 21 on the filter screen 2, the bottom of the placement tank 16 can be sealed, reducing the amount of water entering the placement hole from the bottom of the placement tank 16 during the pumping process, thereby reducing the amount of debris entering the pump body from the placement tank 16.

[0052] By providing a bent end 22 on the sealing plate 21, and having the bent end 22 in contact with the side of the float base 1, and providing a through hole for the water outlet pipe to pass through on the bent end 22, the sealing plate 21 can be limited, reducing the possibility of the sealing plate 21 detaching from the float base 1.

[0053] Since the sealing plate 21 and the filter screen 2 are integrated, the filter screen 2 slides and engages with the L-shaped slide rail 14, and is connected to the water outlet pipe through the bent end 22, which ensures the stability of the filter screen 2 during operation.

[0054] In some embodiments, such as Figures 1 to 8 As shown, the float base 1 is connected to the periphery of the placement groove 16 with a threaded sleeve 17, and the bent end 22 of the sealing plate 21 has a through hole for insertion and engagement with the threaded sleeve 17; after the bent end 22 of the sealing plate 21 is inserted and engaged with the threaded sleeve 17, the sealing plate 21 is fixed to the float base 1 by bolts.

[0055] The threaded sleeve 17 is fixed on the side wall of the float base 1. After the bent end 22 of the sealing plate 21 is inserted and engaged with the threaded sleeve 17, the sealing plate 21 can be fixed on the float base 1 by the engagement of the bolt and the threaded sleeve 17, thereby making the position of the filter screen 2 relatively fixed and improving the stability of the filter screen 2 during operation.

[0056] The bent end 22 of the sealing plate 21 is connected by bolts and threaded sleeve 17, which facilitates the disassembly and assembly of the sealing plate 21 and makes it easy to replace the filter screen 2 after it is damaged.

[0057] In some embodiments, such as Figures 1 to 8As shown, there is a support 4 between the hinge end of the rocker arm 32 and the bottom of the float base 1, and the support 4 has a through hole for the rotating shaft 31 to pass through.

[0058] By setting a support base 4 between the swing rod 32 and the float base 1, and setting a through hole on the support base 4, the top of the swing rod 32 can be matched with the bottom position of the L-shaped slide 14, and the swing rod 32 can swing through the bottom of the L-shaped slide 14, avoiding interference from the L-shaped slide 14 to the swing rod 32.

[0059] In some embodiments, such as Figures 1 to 8 As shown, the outer peripheral wall of the end of the rotating shaft 31 that passes through the floating body base 1 has an annular groove 311, and there are two arc-shaped plates 5 on the annular groove 311. Each arc-shaped plate 5 is connected to the rotating shaft 31 by bolts; wherein, the bottom of the arc-shaped plate 5 is in contact with the bottom wall of the mounting groove 11.

[0060] By setting an annular groove 311 on the rotating shaft 31 and connecting it to the annular groove 311 with two arc-shaped plates 5, the arc-shaped plates 5 can support the rotating shaft 31 and prevent it from falling down; the arc-shaped plates 5 and the support base 4 can cooperate to limit the axial movement of the rotating shaft 31.

[0061] The arc plate 5 is connected to the rotating shaft 31 by bolts. When the swing arm 32 needs to be replaced, the arc plate 5 can be removed from the rotating shaft 31, and the rotating shaft 31 can be pulled out from the bottom of the float base 1, which makes it easier to replace the swing arm 32.

[0062] In some embodiments, such as Figures 1 to 8 As shown, the drive structure includes a bracket 6 and a servo motor 7; the bracket 6 is connected to the bottom wall of the mounting slot 11 at the position of the rotating shaft 31; the servo motor 7 is mounted on the bracket 6; the output shaft of the servo motor 7 is connected to the rotating shaft 31 through a coupling; a power supply for supplying power to the servo motor 7 is provided in the mounting slot.

[0063] After the arc plate 5 is installed on the rotating shaft 31, the rotating shaft 31 is in place and can be axially limited. The output shaft of the servo motor 7 is connected to the rotating shaft 31 through a coupling, so that the power of the servo motor 7 can be transmitted to the rotating shaft 31. The servo motor 7 can precisely control the swing angle of the swing arm 32, so that the brush 33 on the swing arm 32 can clean the debris on the filter screen 2.

[0064] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
