The definition of water pump: usually the machine that lifts liquid, transports liquid or increases the pressure of liquid, that is, the machine that converts the mechanical energy of the prime mover into liquid energy to achieve the purpose of pumping liquid is collectively called a pump. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals, etc. It can also transport liquids, gas mixtures and liquids containing suspended solids. The technical parameters for measuring the performance of water pumps include flow rate, suction head, head, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volumetric water pumps, vane pumps and other types.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 4 As shown, a submersible pump described in the utility model includes a pump body 1, a shell 2 is fixedly installed on the outer wall of the pump body 1, a cleaning mechanism 3 is arranged at the lower part of the shell 2, and the cleaning mechanism 3 includes a cleaning plate 32. A plurality of water troughs are arranged in an array on the lower surface of the shell 2. There are several cleaning plates 32, which are used in conjunction with the water troughs. A traction mechanism 4 is arranged on the outer wall of the shell 2.

[0023] Eliminating the filter hole and adopting the water trough design can make the design of the cleaning mechanism 3 simpler, and the filter hole is compared with the water trough, and the water trough can increase the water inlet flow rate, thereby improving the operating efficiency of the pump body 1.

[0024] Specifically, the cleaning mechanism 3 also includes a movable plate 31, there are two movable plates 31, and the two movable plates 31 are symmetrically arranged. The outer wall of the shell 2 is provided with a movable groove, and the movable plate 31 is slidably installed in the movable groove and passes through the side wall of the shell 2. A plurality of cleaning plates 32 are fixedly installed in an array on the lower surface of the movable plate 31.

[0025] Specifically, the cleaning plates 32 are in the shape of a right triangle, and the right-angled sides of two adjacent cleaning plates 32 are opposite to each other.

[0026] Operating the traction mechanism 4 can drive the movable plate 31 to slide along the movable groove, and then drive the cleaning plate 32 to move. The cleaning plate 32 is embedded in the water trough, so the blockage in the water trough can be cleaned during the movement of the cleaning plate 32. The right-angled triangle design of the cleaning plate 32 can facilitate the discharge of the blockage. When the pump body 1 is in operation, there is no need for manual pulling of the rope, which solves the problem of wasting time and manpower during use and improves operating efficiency.

[0027] Specifically, two vertical plates 311 are fixed to the upper surfaces of both ends of each movable plate 31 , and a common elastic rope 312 is fixed between the two diagonally opposite vertical plates 311 .

[0028] The elastic rope 312 will be stretched during the sliding process of the movable plate 31 , and when the cleaning operation is completed, the cleaning mechanism 3 can be reset under the action of the elastic potential energy of the elastic rope 312 .

[0029] Specifically, the traction mechanism 4 includes a first fixed pulley 41, and there are four first fixed pulleys 41 in total. The four first fixed pulleys 41 are all rotatably installed on the side wall of the shell 2, and the four first fixed pulleys 41 are respectively located above the two ends of the movable groove. Two second fixed pulleys 42 are rotatably installed on the side wall of the shell 2 on the same side as the first fixed pulley 41, and the second fixed pulley 42 is located in the middle above the side wall of the shell 2. A pull rope 43 is fixed to the end of the movable plate 31 that passes through the shell 2, and the pull rope 43 is wound around the first fixed pulley 41 and the second fixed pulley 42. One of the pull ropes 43 is wound around the second fixed pulley 42 on the same side and then merges with another pull rope 43 on another second fixed pulley 42.

[0030] Specifically, two third fixed pulleys 44 are rotatably installed on the shell 2, and the two third fixed pulleys 44 are respectively located at the corners of the second fixed pulley 42 where the pull rope 43 merges. The axis of the third fixed pulley 44 is perpendicular to the bottom surface of the shell 2. The pull rope 43 is wound through the third fixed pulley 44, and a rotating wheel 45 is rotatably installed on the side wall of the shell 2 where the second fixed pulley 42 is not provided. The two pull ropes 43 are wound through the ends of the second fixed pulley 42 and are fixed on the rotating wheel 45, and a turning handle 46 is fixedly installed on the side wall of the rotating wheel 45.

[0031] Turning the handle 46 can drive the rotating wheel 45 to rotate, and then drive the pull rope 43 to be wound around the rotating wheel 45. Since the pull rope 43 is successively wound through the third fixed pulley 44, the second fixed pulley 42 and the first fixed pulley 41, and the end of the pull rope is fixed on the movable plate 31, the process of turning the handle 46 will eventually drive the movable plate 31 to move through the transmission, and then drive the cleaning mechanism 3 to operate.

[0032] Working principle: when cleaning operation is required, the handle 46 is turned, and the handle 46 can drive the rotating wheel 45 to rotate, thereby driving the pull rope 43 to be wound around the rotating wheel 45. Since the pull rope 43 is successively wound through the third fixed pulley 44, the second fixed pulley 42 and the first fixed pulley 41, and the end of the pull rope is fixed on the movable plate 31, the process of turning the handle 46 will eventually drive the movable plate 31 to move through the transmission, and the movable plate 31 slides along the movable groove, thereby driving the cleaning plate 32 to move. The cleaning plate 32 is embedded in the water trough, so the blockage in the water trough can be cleaned during the movement of the cleaning plate 32.

[0033] It should be mentioned that the right-angled triangle design of the cleaning plate 32 can facilitate the discharge of blockages. When the pump body 1 is in operation, there is no need for manual pulling of the rope, which solves the problem of wasting time and manpower during use and improves operating efficiency.
