Background
The submersible pump is widely applied to the fields of capital construction, agricultural irrigation, discharge of industrial sewage and the like. Before the submersible pump starts to work, the suction pipe and the pump body need to be filled with liquid; after the pump is started, the impeller rotates at a high speed, liquid entering the pump rotates along with the blades and is ejected outwards under the action of centrifugal force, the speed of the ejected liquid in the pump shell diffusion chamber gradually becomes slow, the pressure of the ejected liquid gradually increases, and then the ejected liquid flows out from the outlet and the discharge pipe in the pump. At this time, the liquid is thrown around the center of the vane to form a vacuum low-pressure region without air and liquid, and the liquid outside the pump body flows into the pump through the suction pipe under the action of atmospheric pressure, and is continuously sucked and discharged. When the submersible pump is applied to the field of sewage treatment, a long fiber, a cloth bag and the like in sewage can be cut off and torn by a self-provided crushing channel structure generally and then smoothly discharged, but the crushing structure is generally directly connected with a motor shaft, if more sucked dirt is accumulated, large impact is easily caused on a rotor, the service life of the motor is influenced, and the motor can be stopped if serious, in addition, in the scheme disclosed by the invention with the application number of CN201611242051.0, the purpose of blocking removal is achieved by utilizing back washing on an inlet, but an additional control system is required for controlling the motor to stop and rotate reversely, impurities after back washing are still remained around a water suction port, and the more the impurities are accumulated, so that the number of back washing is frequent, and the working efficiency is influenced.

The inner cover 22 rotates on the inner side of the outer cover 21 by the driving force of the driving shaft 13, the driving shaft 13 is connected with the output shaft of the motor by a reduction box for reducing speed, a reduction gear set is also used between the driving shaft 13 and the inner cover 22 for further reducing the rotating speed of the inner cover 22, because the outer cover 21 is provided with the longitudinal dense filtering area 201 and the longitudinal sparse filtering area 202, namely the flow velocity of water flow in the longitudinal dense filtering area 201 is small, the flow velocity in the longitudinal sparse filtering area 202 is large, the water baffle area 221 of the inner cover 22 can be impacted upwards by water flow in the area with large flow velocity, the whole inner cover 22 can move upwards, the water baffle area 221 of the inner cover 22 can descend again in the area with small flow velocity due to gravity, so that the relative longitudinal displacement between the inner cover 22 and the outer cover 21 is realized, and the effect is more obvious after the longitudinal dense filtering area 201 is blocked by sewage in the water environment, so that the longitudinal dense filtering area 201 and the longitudinal sparse filtering area 202 between the inner cover 22 and the outer cover 21 can be overlapped and staggered Under the condition of (1), the sewage enters the inner cover 22 intermittently and then enters the impeller shell 11, so that a large amount of sewage in the water environment cannot enter the impeller shell 11 at one time, and the intermittent filtering and cutting action between the inner cover 22 and the outer cover 21 is utilized to ensure that the sewage enters intermittently under the condition of not influencing water inlet.
Specifically, as shown in fig. 2-3, solid plates 211 and dense-hole filter plates 212 which are distributed in a staggered manner are arranged on the longitudinal dense-filtration zone 201, dense-hole filter plates 212 and dense-hole filter plates 213 which are distributed in a staggered manner are arranged on the longitudinal sparse-filtration zone 202, solid plates 211 and dense-hole filter plates 212 which are distributed in a staggered manner are arranged on the transverse dense-filtration zone 203, and dense-hole filter plates 212 and dense-hole filter plates 213 which are distributed in a staggered manner are arranged on the transverse sparse-filtration zone 204.
The longitudinal dense filter area 201 is composed of solid plates 211 and dense-hole filter plates 212 which are distributed in a staggered mode, when water flow enters the outer cover 21 in the longitudinal dense filter area 201, the flow speed is relatively low, if the dense-hole filter plates 212 are blocked by dirt in the water environment, the flow speed is further reduced, the longitudinal sparse filter area 202 is composed of dense-hole filter plates 212 and sparse-hole filter plates 213 which are distributed in a staggered mode, when the water flow enters the outer cover 21 through the longitudinal sparse filter area 202, the flow speed is relatively high, so that a flow speed difference is formed between the longitudinal dense filter area 201 and the longitudinal sparse filter area 202, when the inner cover 22 rotates in the outer cover 21, due to the flow speed difference, pressure at the position of the water baffle area 221 is changed discontinuously, the width of the water baffle area 221 is the same as the widths of the longitudinal dense filter area 201 and the longitudinal sparse filter area 202, or is slightly smaller than the widths of the longitudinal dense filter area 201 and the longitudinal sparse filter area 202, therefore, the state switching of the water-resisting plate area 221 between the longitudinal dense filtering area 201 and the longitudinal sparse filtering area 202 is obvious, the widths of the longitudinal dense filtering area 201 and the longitudinal sparse filtering area 202 are the same or the width of the longitudinal sparse filtering area 202 is slightly larger, and the passing capacity of the outer cover 21 can be increased; the transverse dense filtration area 203 consists of a solid plate 211 and a dense-hole filter plate 212, and the transverse sparse filtration area 204 consists of a dense-hole filter plate 212 and a sparse-hole filter plate 213, so that the trafficability of the transverse sparse filtration area 204 is greater than that of the transverse dense filtration area 203, and the transverse trafficability can interact with the liftable inner cover 22 to change the trafficability state of the whole water inlet cover 2 to the dirt in the water environment.
