[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a water pump for municipal water supply and drainage, including a pipe body 1, a cleaning mechanism 2 is arranged inside the pipe body 1, the cleaning mechanism 2 includes a bracket 21, the bracket 21 is in the shape of a rectangular parallelepiped, the left and right ends of the bracket 21 are fixedly connected to the inner wall of the pipe body 1, the bottom end of the bracket 21 is rotatably connected to a rotating rod 22, the rotating rod 22 is in the shape of a cylindrical column above and a long rod with a circular top and a triangular bottom gradient below, and the triangle is an inscribed regular triangle of a circle, the bottom end of the rotating rod 22 is fixedly connected to a magnetic block 211, the outer wall of the rotating rod 22 is fixedly connected to an impeller blade 23, and the impeller blade 23 is arranged in the cylindrical area of ​​the rotating rod 22.

[0032] Reference Figure 1 - Figure 3 The cleaning mechanism 2 also includes a fixing ring 24, the outer wall of which is fixedly connected to the inner wall of the tube body 1, and a fixing ring 25 is fixedly connected to the inner wall of the tube body 1 below the fixing ring 24. The fixing ring 24 and the fixing ring 25 are both arranged in a circular ring shape, and a filter plate 26 is slidably connected to the inner wall of the tube body 1 between the fixing ring 24 and the fixing ring 25. A through hole is provided on the surface of the filter plate 26 for water to pass through, and a control rod 27 runs through the middle of the filter plate 26.

[0033] Reference Figure 1 - Figure 3 The control rod 27 is fixedly connected to the outer wall above the filter plate 26 with a limiting ring 210. The diameter of the limiting ring 210 is larger than the through hole opened in the middle of the filter plate 26 for the control rod 27 to pass through. The setting of the limiting ring 210 ensures that the control rod 27 will not fall. The top of the control rod 27 is provided with a notch whose shape matches the shape of the lower end of the rotating rod 22. The shape of the notch and the shape of the rotating rod 22 ensure that when the bottom of the rotating rod 22 enters the control rod 27, it can drive the control rod 27 to rotate.

[0034] Reference Figure 1 - Figure 3, a second magnetic block 212 is arranged inside the control rod 27, and the bottom end of the first magnetic block 211 is different from the top magnetic pole of the second magnetic block 212. Through the setting of the first magnetic block 211 and the second magnetic block 212 and the magnetic poles, it is ensured that when the first magnetic block 211 and the second magnetic block 212 are close to a certain distance, a force approaching each other can be generated, and the outer wall of the bottom end of the control rod 27 is fixedly connected with a scraper 28, and the top end of the filter plate 26 is elastically connected to the bottom end of the fixing ring 24 through an elastic telescopic rod 29. The elastic telescopic rod 29 is a shape formed by connecting a plurality of hollow cylinders with a spring. Through the setting of the hollow cylinder, it is ensured that the spring is not easily damaged by water ingress, and the elastic force of the elastic telescopic rod 29 is greater than the elastic force between the first magnetic block 211 and the second magnetic block 212, and is less than the water suction force of the water pumping pipe. Through the comparison between the elastic telescopic rod 29 and the magnetic force, it is ensured that when there are fewer impurities adhering to the bottom of the filter plate 26, the filter plate 26 can move downward and reset under the action of the elastic force of the elastic telescopic rod 29.

[0035] Reference Figure 1 , Figure 2 and Figure 4 The collecting assembly 3 is arranged inside the tube body 1. The collecting assembly 3 includes a mounting plate 31. The mounting plate 31 is installed obliquely. The outer wall of the mounting plate 31 is fixedly connected to the inner wall of the tube body 1. The inner wall of the mounting plate 31 is provided with a water inlet hole 32. The inner wall of the water inlet hole 32 is rotatably connected with a push plate 33. The lower end of the push plate 33 is elastically connected to the inner wall of the water inlet hole 32 through a spring sheet 34. One end of the spring sheet 34 is fixedly connected to the lower end of the push plate 33, and the other end of the spring sheet 34 is fixedly connected to the inner wall of the water inlet hole 32. The tube body 1 The right end is fixedly connected with a cleaning tube 35, the interior of the cleaning tube 35 is connected with the interior of the tube body 1, and the shape of the cleaning tube 35 is a rectangular pipe at the upper end, a square pipe at the upper end and a circular pipe at the lower end, which are gradually connected to a hollow cylindrical pipe at the lower end. The outer wall of the cleaning tube 35 is threadedly connected with a cleaning cylinder 36. Through the shape setting of the cleaning tube 35, it is ensured that the upper part of the cleaning tube 35 can be in the same plane with the mounting plate 31, and the lower part can be threadedly connected with the cleaning cylinder 36.

[0036] Working principle: When the staff uses the water pump, the water flows through the bottom end of the pipe body 1 toward the top end of the pipe body 1 under the action of suction. When it flows to the water inlet hole 32, the water pushes the push plate 33 to move upward, so that larger impurities are filtered out.

[0037] When the filter 26 is used for a long time, smaller particles of impurities adhere to the bottom of the filter plate 26. At this time, since the filter plate 26 is blocked, only a small amount of water can pass through the filter plate 26. Therefore, the filter plate 26 moves upward under the action of suction. After the filter plate 26 moves upward, the lower end of the rotating rod 22 just enters the groove at the upper end of the control rod 27.

[0038] Since the bottom end of the rotating rod 22 is a triangle and is an inscribed equilateral triangle of the circle above, after the rotating rod 22 enters the groove above the control rod 27, it can be controlled by the inner wall of the groove to ensure that the rotating rod 22 just enters the control rod 27, and through the inner wall of the triangle below, the impeller blade 23 drives the rotating rod 22 to rotate, thereby driving the control rod 27 to rotate.

[0039] At the same time, after the rotating rod 22 enters the inside of the control rod 27, the magnetic block 1 211 is close to the magnetic block 212. Therefore, the control rod 27 can move a part upward under the action of the magnetic force, so that the magnetic block 1 211 contacts the magnetic block 212, so that the control rod 27 drives the scraper 28 to move upward, so that the top end of the scraper 28 contacts the bottom end of the filter plate 26 and rotates under the drive of the control rod 27, thereby achieving the cleaning effect of the filter plate 26.

[0040] When the cleaning is completed, since the water can flow out through the filter plate 26, the suction force on the filter plate 26 is reduced at this time, so the filter plate 26 is reset under the action of the elastic telescopic rod 29. When the filter plate 26 is reset, the distance between the magnetic block 1 211 and the magnetic block 212 is relatively far, so the control rod 27 moves downward under the action of gravity at this time, and the control rod 27 is limited by the limit ring 210 to prevent the control rod 27 from falling.

[0041] When the impurities are cleaned and dropped by the scraper 28, they move downward under the action of gravity and fall on the top of the mounting plate 31. Since the mounting plate 31 is installed at an angle, the impurities slide to the right under the action of gravity and enter the cleaning pipe 35. When the staff needs to clean the impurities, they only need to open the cleaning cylinder 36 to clean the impurities.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
