Problems solved by technology

In this patent, there is a phenomenon that one end of the centrifugal pump will idle for a long time before pumping water, resulting in the problem that the device is very easy to damage, and because the rotation of the rotor of the motor will inhale the dust, resulting in the problem of poor dustproof effect, and finally the plug leaks in the The outside leads to the problem that accidents are likely to occur due to water on the plug when the power is plugged in

Embodiment 1

[0038] refer to Figure 1-3 , the present invention provides a centrifugal pump, comprising a fixed frame 1, the middle part of the upper end of the fixed frame 1 is fixedly connected with a pump body 4, the pump body 4 is the power device of the device, and the left side of the upper end of the fixed frame 1 is fixedly connected with a limiting groove 11. The inner side of the upper end of the groove 11 is fixedly connected with the water tank 8, the limit groove 11 can fix the bottom of the water tank 8, and the middle part of the bottom end of the water tank 8 is slidingly connected with the blocking plate 10, and when the blocking plate 10 is pushed upward by the water flow, the water can be introduced To the inner side of the water tank 8, the output end of the pump body 4 passes through the right wall of the water tank 8 and is fixedly connected with the impeller disc 5, and the impeller disc 5 is driven by the pump body 4 to rotate so as to swing the water upward. Drain...

Embodiment 2

[0040] refer to figure 1 , 4 Compared with Embodiment 1, the present embodiment is slidably connected to the upper end of the fixed frame 1 with a slide plate 2, and the left side of the upper end of the slide plate 2 is fixedly connected with a housing 20, and the slide plate 2 is slid through the housing 20. The right wall of the housing 20, etc. The distance positions are fixedly connected with support rods 22, and the air can be stirred when the inside of the pump body 4 rotates, thereby driving the sponge reel 23 on the support rods 22 to rotate. The middle part of the right wall of the housing 20 is provided with a cooling plate 18. 18 is used to protect the right end of the pump body 4, and the outside of the support rod 22 is connected with a sponge reel 23 for rotation, and the sponge reel 23 is used to stick dust. The copper ring 19 is used to contact the pump body 4 to dissipate heat. Ventilation holes 21 are arranged at equidistant positions on the side walls of t...

Embodiment 3

[0042] refer to figure 1 , 5 Compared with Embodiment 1 and Embodiment 2, the pump body 4 of the present embodiment is connected to the plug 17 through the transmission line 3, and the left and right ends of the plug 17 are connected with rotating plates 16 in rotation, and the rotating plates 16 on both sides of the plug 17 can be Rotate, the adjacent sides of the rotating plate 16 are respectively connected with the left and right ends of the fixed groove 13, the inner top of the fixed groove 13 is connected with one end of the protective shell 15 through the elastic rubber 14, and one end of the protective shell 15 is provided with a socket, and the elastic rubber 14. One end of the socket of the protective shell 15 can be moved to the electric terminal of the plug 17.

[0043]Working principle: the impeller disc 5 can be rotated through the pump body 4, and the valve 7 can be closed when the water flow on the side of the water inlet pipe 9 is not pumped up, and the water ...

Abstract

The invention relates to the technical field of centrifugal pumps, and discloses a centrifugal pump, which comprises a fixing frame, wherein a pump body is fixedly connected to the middle of the upper end of the fixing frame, a limiting groove is fixedly connected to the left side of the upper end of the fixing frame, a water groove is fixedly connected to the inner side of the upper end of the limiting groove, a blocking plate is slidably connected to the middle of the bottom end of the water groove, the output end of the pump body penetrates through the right wall of the water groove to be fixedly connected with an impeller disc, and the rear side of the upper end of the water groove is fixedly connected with a drainage pipe. According to the invention, water guided into the inner side of a water groove can flow towards a water inlet pipe side, so that the idling time of a pump body can be shortened, and the effect of protecting the pump body is achieved; a sponge winding drum is driven to rotate through air flowing so as to adsorb dust, so that the dustproof effect is achieved; and by rotating arotating plate, a fixing groove is pushed out under the action of an elastic rubber, so that the power connection end of a plug is inserted into the inner side of a protection shell, water cannot enter the plug when the plug is not used, and the problem of short circuit cannot be generated when the plug is used.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a centrifugal pump. Background technique [0002] Centrifugal pumps work by rotating the impeller to cause the water to move centrifugally. Before starting the pump, the pump casing and the suction pipe must be filled with water, and then the motor is started to drive the impeller and the water to rotate at a high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller, and flows through the volute pump casing. The pressure water pipeline flowing into the water pump. Chinese patent document CN202020782849.X relates to the technical field of centrifugal pumps. It provides a centrifugal pump, which includes a support, a pump casing mounted on the support, an impeller installed in the pump casing, and a pump shaft supporting the impeller. The pump shaft passes through the support There is a liquid inlet in the middle of the front end...
