[0038] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in combination with specific embodiments:

[0039] Please refer to Figure 1 With Figure 2The lifting mechanism for the submersible sewage pump in one embodiment comprises a guide rod 100, a sewage suction device 200, a lifting bracket 300 and a chain 400. The first end of the guide rod 100 is located in the sewage pool 10 and is fixedly connected to the sewage inlet end 6011 of the sewage pipe 601. The rod wall of the guide rod 100 is used to be slidingly fitted in the limiting groove 7011 of the submersible sewage pump 701 to guide the sewage outlet 7012 of the submersible sewage pump 701 to be connected or separated from the sewage inlet end 6011. The sewage suction device 200 and the lifting bracket 300 are fixedly arranged outside the sewage pool 10. The second end of the guide rod 100 extends towards the sewage suction device 200 and is fixedly connected to the lifting bracket 300. The lifting end of the lifting bracket 300 is located above the sewage pool 10, and the chain 400 is installed on the lifting end. Part of the chain 400 is located in the sewage pool 10 and is used to be connected to the submersible sewage pump 701. The chain 400 is used to pull the submersible sewage pump 701 to slide along the guide rod 100, so that the sewage outlet 7012 of the submersible sewage pump 701 is connected to the air inlet 2201 of the sewage suction device 200.

[0040] It can be understood that, since the second end of the guide rod 100 extends towards the sewage suction device 200 fixedly arranged outside the sewage pool 10 and is fixedly connected to the lifting bracket 300 fixedly arranged outside the sewage pool 10, and the first end of the guide rod 100 is fixedly connected to the sewage inlet end 6011 of the sewage pipe 601 in the sewage pool 10, the rod wall of the guide rod 100 is slidingly fitted in the limiting groove 7011 of the submersible sewage pump 701, so that the submersible sewage pump 701 can be guided to slide through the guide rod 100. Since the lifting end of the lifting bracket 300 located above the sewage pool 10 has the chain 400 installed thereon, when the submersible sewage pump 701 is blocked, part of the chain 400 can be connected to the submersible sewage pump 701 in the sewage pool 10, so that the submersible sewage pump 701 can be lifted by the pulling force provided by the chain 400. At this time, the sewage outlet 7012 of the submersible sewage pump 701 is separated from the sewage inlet end 6011 of the sewage pipe 601. Then, the submersible sewage pump 701 slides along the guide rod 100, so that the sewage outlet 7012 of the submersible sewage pump 701 is connected to the air inlet 2201 of the sewage suction device 200. In this way, the waste materials such as fibers and paper that are easy to cause blockage and are blocked in the submersible sewage pump 701 can be quickly sucked out by the sewage suction device 200 to quickly clean the submersible sewage pump 701. This can not only reduce the labor cost, but also make the operation simpler.

[0041] Please refer to Figure 1 and Figure 3In some embodiments, the suction device 200 includes a negative pressure box 210 and a telescopic air pipe 220. The negative pressure box 210 is fixedly arranged outside the sewage pool 10. The telescopic air pipe 220 is fixedly installed on the negative pressure box 210. A first end of the telescopic air pipe 220 is communicated with a negative pressure suction nozzle of the negative pressure box 210. A second end of the telescopic air pipe 220 forms a suction port 2201. It can be understood that, since the first end of the telescopic air pipe 220 fixedly installed on the negative pressure box 210 is communicated with the negative pressure suction nozzle of the negative pressure box 210, and the suction port 2201 of the suction device 200 is formed at the second end of the telescopic air pipe 220, when the submersible sewage pump 701 is lifted by the chain 400 to abut against the suction device 200, the suction port 2201 can be more flexibly adapted and docked with the sewage outlet 7012 of the submersible sewage pump 701 by stretching the telescopic air pipe 220. Then, suction force is provided by the negative pressure suction nozzle of the negative pressure box 210, so that the suction port 2201 of the suction device 200 can more quickly suck out the waste materials such as fibers and paper in the sewage outlet 7012 of the submersible sewage pump 701 which are easy to cause blockage.

[0042] Please refer to Figure 3 In some embodiments, the telescopic air pipe 220 forms a first locking flange 2211 around the outer periphery of the suction port 2201. The first locking flange 2211 is used to be locked and matched with a second locking flange 7013 around the outer periphery of the sewage outlet 7012 of the submersible sewage pump 701. Since the telescopic air pipe 220 forms the first locking flange 2211 around the outer periphery of the suction port 2201, when the suction port 2201 of the suction device 200 is docked with the sewage outlet 7012 of the submersible sewage pump 701, the first locking flange 2211 can be tightly matched with the second locking flange 7013 around the outer periphery of the sewage outlet 7012 of the submersible sewage pump 701 by locking, so that the suction force of the suction port 2201 of the suction device 200 can act more on the waste materials such as fibers and paper in the sewage outlet 7012 of the submersible sewage pump 701 which are easy to cause blockage.

[0043] Please refer to Figure 1 In some embodiments, the lifting support 300 includes a pressure bearing pile 310 and a hoisting frame 320. The pressure bearing pile 310 is vertically fixed outside the sewage pool 10. The hoisting frame 320 is fixedly installed on the upper end of the pressure bearing pile 310. The top end of the hoisting frame 320 is located above the sewage pool 10. The chain 400 is liftingly installed on the top end of the hoisting frame 320. It can be understood that, since the pressure bearing pile 310 is vertically fixed outside the sewage pool 10, and the top end of the hoisting frame 320 fixedly installed on the upper end of the pressure bearing pile 310 is located above the sewage pool 10, the compactness of the structure of the lifting support 300 can be improved, so that the chain 400 liftingly installed on the top end of the hoisting frame 320 can more stably lift the submersible sewage pump 701.

[0044] Please refer to Figure 1 With Figure 4In some embodiments, the lifting frame 320 comprises a frame structure 3210 fixedly arranged on the upper end of the pressure bearing pile 310, and a sprocket 3220 rotatably arranged on the frame structure 3210 and above the sewage pool 10. At least part of the chain 400 is wound on the sprocket 3220, so that the chain 400 is wound or unwound on the sprocket 3220. It can be understood that, since the sprocket 3220 is rotatably arranged on the frame structure 3210 fixed on the pressure bearing pile 310, and at least part of the chain 400 is wound on the sprocket 3220, the chain 400 can be wound on the sprocket 3220 by driving the sprocket 3220 to rotate relative to the frame structure 3210, so that the chain 400 lifts the submersible sewage pump 701, or the chain 400 is unwound on the sprocket 3220, so that the chain 400 lowers the submersible sewage pump 701, so as to realize the lifting or lowering of the submersible sewage pump 701 by the chain 400.

[0045] Referring to Figure 4 In some embodiments, the lifting frame 320 further comprises a rotary driver (not shown in the figure). The rotary driver is fixedly arranged on the frame structure 3210, and the power output end of the rotary driver is coaxially fixedly connected with the rotating shaft of the sprocket 3220. It can be understood that, since the power output end of the rotary driver fixedly arranged on the frame structure 3210 is coaxially fixedly connected with the rotating shaft of the sprocket 3220, the rotating shaft of the sprocket 3220 can be synchronously rotated by the power output end of the rotary driver, so as to realize the automatic winding and unwinding of the chain 400, and further reduce the labor cost.

[0046] Referring to Figure 1 In some embodiments, a pump body dismounting opening 101 is formed between the second end of the guide rod 100 and the bottom end of the lifting frame 320, and the pump body dismounting opening 101 is used for mounting or dismounting the submersible sewage pump 701 on the guide rod 100. It can be understood that, since the pump body dismounting opening 101 is formed between the second end of the guide rod 100 and the bottom end of the lifting frame 320, when the submersible sewage pump 701 has a major failure, the submersible sewage pump 701 can be lifted to the pump body dismounting opening 101 by the chain 400, so that the limiting groove 7011 of the submersible sewage pump 701 is disengaged from the rod wall of the guide rod 100, so that the submersible sewage pump 701 can be removed from the guide rod 100 through the pump body dismounting opening 101 for maintenance. After the maintenance of the submersible sewage pump 701 is completed, the limiting groove 7011 of the submersible sewage pump 701 can be re-engaged with the rod wall of the guide rod 100 through the pump body dismounting opening 101. In this way, the submersible sewage pump 701 can be quickly mounted or dismounted on the guide rod 100 through the pump body dismounting opening 101.

[0047] Referring to Figure 1 With Figure 3In some embodiments, the guide rod 100 is arranged parallel to the pressure pile 310, and a cleaning position 102 is formed between the second end of the guide rod 100 and the bottom of the pressure pile 310; the suction inlet 2201 of the suction device 200 is arranged towards the cleaning position 102. It can be understood that, since the guide rod 100 is arranged parallel to the pressure pile 310, and the cleaning position 102 is formed between the second end of the guide rod 100 and the bottom of the pressure pile 310, the submersible sewage pump 701 can be gently guided to rise and enter the cleaning position 102 through the guide rod 100, and at this time the suction inlet 2201 of the suction device 200 can better align with the sewage outlet 7012 of the submersible sewage pump 701.

[0048] Referring to Figure 3 In some embodiments, the connection assembly 500 is fixedly arranged on the pressure pile 310; the connection assembly 500 includes a fixedly arranged screw plate part 510 and a triangular welding part 520, the screw plate part 510 is locked to the pressure pile 310 by a plurality of screws, and the triangular welding part 520 is welded to the guide rod 100. It can be understood that, since the screw plate part 510 is locked to the pressure pile 310 by a plurality of screws, and the triangular welding part 520 is fixedly connected to the guide rod 100 by welding, the pressure pile 310 can be more firmly connected to the guide rod 100 through the connection assembly 500.

[0049] Referring to Figures 1 to 4 The present disclosure also provides a pump body maintenance device including the submersible sewage pump lifting and cleaning mechanism of any of the above embodiments. It can be understood that, by applying the submersible sewage pump lifting and cleaning mechanism of the present disclosure to the pump body maintenance device, since the second end of the guide rod 100 extends towards the suction device 200 fixedly arranged outside the sewage pool 10 and is fixedly connected to the lifting bracket 300 fixedly arranged outside the sewage pool 10, and the first end of the guide rod 100 is fixedly connected to the sewage inlet end 6011 of the sewage pipe 601 in the sewage pool 10, and the rod wall of the guide rod 100 is slidingly fitted in the limiting groove 7011 of the submersible sewage pump 701, the submersible sewage pump 701 can be guided to slide through the guide rod 100. Since the lifting end of the lifting bracket 300 located above the sewage pool 10 is installed with the chain 400, when the submersible sewage pump 701 is blocked, the chain 400 can be connected to the submersible sewage pump 701 in the sewage pool 10 to provide a pulling force to lift the submersible sewage pump 701, at this time the sewage outlet 7012 of the submersible sewage pump 701 is separated from the sewage inlet end 6011 of the sewage pipe 601, and then the submersible sewage pump 701 slides along the guide rod 100, so that the sewage outlet 7012 of the submersible sewage pump 701 is connected to the suction inlet 2201 of the suction device 200, and thus the fiber, paper and other easily blocked waste materials blocked in the submersible sewage pump 701 can be quickly sucked out by the suction device 200 to quickly clean the submersible sewage pump 701, which not only reduces the labor cost, but also is easier to operate.

[0050] Compared with the prior art, the present disclosure has at least the following advantages:

[0051] The lifting mechanism for the submersible sewage pump described above, since the second end of the guide rod 100 extends towards the sewage suction device 200 fixed outside the sewage pool 10 and is fixedly connected to the lifting bracket 300 fixed outside the sewage pool 10, and the first end of the guide rod 100 is fixedly connected to the sewage inlet end 6011 of the sewage discharge pipe 601 inside the sewage pool 10, and the rod wall of the guide rod 100 is slidingly fitted in the limiting groove 7011 of the submersible sewage pump 701, so that the submersible sewage pump 701 can be guided to slide through the guide rod 100. Again, the lifting end of the lifting bracket 300 located above the sewage pool 10 is provided with a chain 400, and when the submersible sewage pump 701 is blocked, the chain 400 is connected to the submersible sewage pump 701 inside the sewage pool 10, so that the chain 400 can provide a pulling force to lift the submersible sewage pump 701, at which time the sewage outlet 7012 of the submersible sewage pump 701 is separated from the sewage inlet end 6011 of the sewage discharge pipe 601, and then the submersible sewage pump 701 slides along the guide rod 100, so that the sewage outlet 7012 of the submersible sewage pump 701 is connected in communication with the air inlet 2201 of the sewage suction device 200, so that the fiber, paper and other easily blocked waste materials blocked in the submersible sewage pump 701 can be quickly sucked out by the sewage suction device 200 to quickly clean the submersible sewage pump 701, which not only reduces the labor cost, but also is easier to operate.

[0052] The above-described embodiments only express several embodiments of the present disclosure, and the description is more specific and detailed, but it should not be understood as limiting the scope of the utility model patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present disclosure, a number of modifications and improvements can be made, which are within the scope of the present disclosure. Therefore, the protection scope of the present disclosure patent should be subject to the appended claims.
