Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0016] like Figures 1 to 6 As shown, this anti-clogging submersible pump includes a pump head 1, a water outlet pipe 2 fixedly connected to the side wall of the pump head 1, a housing 3 fixedly connected to the upper end face of the pump head 1, an end cover 4 fixedly connected to the upper end face of the housing 3, an assembly plate 5 fixedly connected inside the housing 3, a motor 6 fixedly connected to the upper end face of the assembly plate 5, a drive end of the motor 6 passing through the assembly plate 5 and fixedly connected to a mounting shaft 7, an impeller 8 fixedly connected to the mounting shaft 7, and a base 9 fixedly connected to the lower end face of the pump head 1. A bidirectional cutting component 10 is provided inside the base 9, and a height adjustment component 11 is provided on the lower side of the base 9. When the motor 6 starts, it drives the mounting shaft 7 to rotate the impeller 8, generating suction and pressure inside the pump head 1, causing water to be drawn in from the lower part of the pump head 1, accelerated by the impeller 8, and discharged from the water outlet pipe 2, thus realizing the water transportation function. The bidirectional cutting component 10 is used to cut debris in the water to prevent clogging, and the height adjustment component 11 can adjust the height of the pump body to adapt to different working environments.

[0017] In this embodiment, like Figures 1 to 5 As shown, the bidirectional cutting assembly 10 includes a mounting plate 1001 fixed to the base 9 by bolts. A mounting cylinder 1002 is fixedly connected to the center of the upper end face of the mounting plate 1001. A first bearing 1003 is fixedly connected to the inner bottom wall of the mounting cylinder 1002. A hollow tube 1004 is fixedly connected to the inner side wall of the inner ring of the first bearing 1003. The bottom of the hollow tube 1004 passes through the mounting plate 1001 and extends to the lower part. A first bevel gear 1005 is fixedly connected to the top of the hollow tube 1004. A second bearing 1006 is fixedly connected to the inner top wall of the mounting cylinder 1002. A rotating shaft 1007 is fixedly connected to the inner side wall of the inner ring of the second bearing 1006. A second bevel gear 1008 is fixedly connected to the rotating shaft 1007. The bottom end of the rotating shaft 1007 passes through the hollow tube 1004 and extends to the lower part. The top end of the rotating shaft 1007 is fixedly connected to... A plug 1009 is connected to the mounting shaft 7. The bottom end of the mounting shaft 7 has a socket that matches the plug 1009. A third bearing 1010 is fixedly connected to the inner wall of the mounting cylinder 1002. A connecting shaft 1011 is fixedly connected to the inner wall of the inner ring of the third bearing 1010. A third bevel gear 1012 is fixedly connected to the connecting shaft 1011 and meshes with the first bevel gear 1005 and the second bevel gear 1008 respectively. When the motor 6 drives the mounting shaft 7 to rotate, the rotating shaft 1007 rotates through the cooperation of the plug 1009 and the socket. The rotation of the rotating shaft 1007 drives the second bevel gear 1008 to rotate. Then, through the transmission of the third bevel gear 1012, it drives the first bevel gear 1005 to rotate, thereby causing the hollow tube 1004 to rotate. This enables the hollow tube 1004 and the rotating shaft 1007 to rotate in both directions, thereby achieving bidirectional cutting and improving the cutting effect.

[0018] To further explain, such as Figure 5 and Figure 6As shown, a first cutting blade 1013 is installed at the bottom of the hollow tube 1004. A first nut 1014 is provided on the lower side of the first cutting blade 1013, and the first nut 1014 is threadedly connected to the hollow tube 1004. A second cutting blade 1015 is installed at the bottom of the rotating shaft 1007. A second nut 1016 is provided on the lower side of the second cutting blade 1015, and the second nut 1016 is threadedly connected to the rotating shaft 1007. A set of first clamps 1017 are evenly fixedly connected inside the inner ring of the first cutting blade 1013. The hollow tube 1004... The hollow tube 1004 has a first opening 1018 that matches the first clamping head 1017. A set of second clamping heads 1019 are evenly fixedly connected to the inner ring of the second cutting blade 1015. The rotating shaft 1007 has a second opening 1020 that matches the second clamping heads 1019. When the hollow tube 1004 and the rotating shaft 1007 rotate respectively, they drive the first cutting blade 1013 and the second cutting blade 1015 to rotate, performing bidirectional cutting of debris in the water entering the lower part of the base 9, improving the cutting effect and preventing debris from clogging the pump body. Figure 5 and Figure 6 As shown, the inner diameter of the hollow tube 1004 is preferably the same as the diameter of the rotating shaft 1007; this allows the rotating shaft 1007 to pass smoothly through the hollow tube 1004, and maintains a relatively stable fit between the two during rotation, ensuring that the rotating shaft 1007 can rotate freely inside the hollow tube 1004 to achieve power transmission.

[0019] like Figure 1 and Figure 3 As shown, the height adjustment component 11 includes a mounting ring 1101 fixed to the outer peripheral side wall of the bottom of the base 9. A bottom ring 1102 is provided on the lower side of the mounting ring 1101. A set of threaded rods 1103 are evenly inserted on the mounting ring 1101. The bottom end of the threaded rods 1103 is fixedly connected to the bottom ring 1102. Two third nuts 1104 are symmetrically threaded on the threaded rods 1103. The two third nuts 1104 are respectively located on the upper and lower sides of the mounting ring 1101. When it is necessary to adjust the height of the pump body, the two third nuts 1104 are loosened, and the mounting ring 1101 is moved up and down to move the base 9 and the entire pump body. After adjusting to a suitable height, the two third nuts 1104 are tightened so that they are respectively close to the upper and lower surfaces of the mounting ring 1101, fixing the position of the mounting ring 1101 on the threaded rods 1103, thereby realizing the adjustment of the pump body height to adapt to different water depths or installation requirements.

[0020] To further explain, such as Figure 1 and Figure 3 As shown, a handle is fixedly connected to the upper end face of the end cover 4, and the impeller 8 is located inside the pump head 1; the handle makes it convenient for operators to carry and move the anti-clogging submersible pump.

[0021] When using this anti-clogging submersible pump: First, loosen the two third nuts 1104. Move the mounting ring 1101 up and down, causing the base 9 and the entire pump body to move. After adjusting to a suitable height, tighten the two third nuts 1104 so that they are tightly against the upper and lower surfaces of the mounting ring 1101, thus adjusting the pump body height. Then, start the motor 6 to drive the mounting shaft 7 to rotate the impeller 8, generating suction and pressure inside the pump head 1. This causes water to be drawn in from the bottom of the pump head 1, accelerated by the impeller 8, and discharged from the outlet pipe 2. At the same time, the motor 6 drives the mounting shaft 7 to rotate. When the plug 1009 engages with the socket, the rotating shaft 1007 rotates. The rotation of the rotating shaft 1007 drives the second bevel gear 1008 to rotate, which in turn drives the first bevel gear 1005 to rotate through the transmission of the third bevel gear 1012. This, in turn, causes the hollow tube 1004 to rotate, enabling the hollow tube 1004 and the rotating shaft 1007 to rotate in both directions. This, in turn, drives the first cutting blade 1013 and the second cutting blade 1015 to rotate, thus cutting debris in the water entering the lower part of the base 9 in both directions, improving the cutting effect and preventing debris from clogging the pump body.

[0022] All technical features in this embodiment can be freely combined according to actual needs.

[0023] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
