DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figures 1-6 As shown, this simple vortex pump for sewage discharge includes a motor 6 and a pump body 1. The pump body 1 has an inlet 14 and an outlet 15, and an impeller cavity 16 connecting the inlet 14 and the outlet 15 is provided inside the pump body 1. Several arc-shaped holes 17 are evenly distributed on the inner wall of the impeller cavity 16, and the arc-shaped holes 17 connect to the outside of the pump body 1. A guide groove 4 is provided on the outer wall of the pump body 1, and a movable connecting plate 5 is provided on the guide groove 4. Several elastic plugs 18 are provided on the connecting plate 5, and the elastic plugs 18 are fitted into the arc-shaped holes 17. Several connecting bolts 2 for connecting the motor 6 are provided on the pump body 1. The connecting plate 5 has a through hole 19 for the connecting bolt 2. The connecting plate 5 moves along the connecting bolt 2. When the water pump starts, the water flows into the impeller cavity 16 from the inlet and is pressurized by the impeller inside and discharged from the inlet. The impurities carried by the water flow are thrown onto the inner wall of the impeller cavity 16 by the impeller. The impurities are heavier than water and are thrown into the arc-shaped hole 17. The arc-shaped hole 17 can reduce the impact of the water flow and cause the impurities to flow back into the impeller cavity 16. After the water pump stops working, the impurities are deposited at the bottom of the arc-shaped hole 17. When cleaning, the connecting plate 5 is used to connect the arc-shaped hole 17 to the outside. The water pump is started, and some water flows out from the arc-shaped hole 17 and washes away the impurities to achieve self-cleaning.

[0022] Preferably, the pump body 1 has symmetrical rotating shafts 9 on both sides, and a connecting lever 8 is provided between the rotating shafts 9. The end of the lever 8 is provided with an extension lever 11, and a guide ring 13 is provided on the extension lever 11. A guide rod 7 is provided on the connecting plate 5. The guide rod 7 is placed inside the guide ring 13. The inner wall of the lever 8 abuts against the end of the pump body 1. The lever 8 and the extension lever 11 form a force-saving lever. When the lever 8 is rotated, the guide ring 13 squeezes the guide rod 7 to achieve force-saving movement. At the same time, the lever 8 and the guide ring 13 can lock the connecting plate 5.

[0023] Preferably, the guide groove 4 has several receiving cavities 12, which are connected to the arc-shaped hole 17. When the moving plate moves, the elastic plug 18 will be bent into the receiving cavity 12 to prevent the elastic plug 18 from being worn excessively.

[0024] Preferably, the elastic plug 18 is hollow, and the top wall of the elastic plug 18 is thinner than the root. When the elastic plug 18 is fitted into the arc-shaped hole 17, the water pressure squeezes the elastic plug 18, causing the head of the elastic plug 18 to be compressed and deformed. The thinner head deforms first, increasing the sealing performance. At the same time, the hollow elastic plug 18 can reduce damage by shrinking during compression.

[0025] Preferably, the water pump body 1 end is provided with a guide fillet 10, the guide fillet 10 is the movement of the lever 8 more smooth.

[0026] Preferably, the connecting bolt 2 is provided with a rotatable identification plaque 3, the identification plaque 3 is in contact with the lever 8, the identification plaque 3 is vertically downward under the natural gravity, preventing the abnormal movement of the lever 8 from causing water leakage.

[0027] Preferably, the impeller cavity 16 is provided with a drainage fillet 20.

[0028] The specific embodiments described herein are merely illustrative of the spirit of the present application. The skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace, but will not deviate from the spirit of the present application or beyond the scope defined by the appended claims.

[0029] Although the water pump body 1, connecting bolt 2, identification plaque 3, guide groove 4, connecting plate 5, motor 6, guide short rod 7, lever 8, rotating shaft 9, guide fillet 10, extension lever 11, containing cavity 12, guide ring 13, water inlet 14, water outlet 15, impeller cavity 16, arc hole 17, elastic plug 18, through hole 19, drainage fillet 20 and other terms are used more in this paper, but it does not exclude the possibility of using other terms. Use these terms is only more convenient to describe and explain the essence of the present application; they are interpreted as any kind of additional limitation is contrary to the spirit of the present application.
