The specific meaning of the above terms in the embodiments of the present invention can be understood by those skilled in the art according to specific situations.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1-2, the present embodiment provides a submersible pump, which mainly includes: a cable protection mechanism, and a motor barrel 11, a pump body 12 and a base 13 which are connected in sequence.

The upper part of the motor barrel 11 is provided with a containing cavity 111 for placing the cable, and a connecting head 112 for connecting the cable is fixed in the containing cavity 111. The motor barrel 11 has a stator, a rotor, and other parts (not shown), which are not modified in the present embodiment, in the motor barrel 11.

A transmission shaft 121 is arranged in the pump body 12, an impeller 122 is mounted on the transmission shaft 121, and a water outlet 123 is arranged on the pump body 12. The drive shaft 121 drives the impeller 122 to rotate, and the impeller 122 makes water enter the pump body 12 from the water inlet and discharges the water from the water outlet 123.

A water inlet is arranged on the base 13, and a filter screen 131 is arranged at the water inlet.

The cable protection mechanism includes a first sleeve 141 and a second sleeve 142. The first sleeve 141 is fixed to the motor barrel 11 and the second sleeve 142 is fixedly connected to the cable. The first sleeve 141 is fixedly provided with a first connecting portion 143, the second sleeve 142 is provided with a second connecting portion 144, and the first connecting portion 143 and the second connecting portion 144 are rotatably connected through a first rotating shaft 145.

Operating personnel is when dragging the upper end of cable, second sleeve 142 can rotate certain angle according to operator's position, the orientation of cable and first sleeve 141 can keep unanimous, the outer wall of cable is difficult by first sleeve 141 wearing and tearing, through reserve the cable of certain length in holding chamber 111, the cable that holds in the chamber 111 can be in the state of laxing, make at second sleeve 142 pivoted in-process, effort between cable and the second sleeve 142 is less, the outer wall of cable is difficult by wearing and tearing, in order to avoid appearing the cable fracture, the circumstances such as electric leakage.

The cable protection mechanism further includes a second rotating shaft 146 and a winding roller 147. The second rotating shaft 146 is rotatably connected in the motor barrel 11, a torsion spring (not shown) is disposed on the second rotating shaft 146, the winding roller 147 is mounted on the second rotating shaft 146, one end of the cable is connected to the connector 112, and the other end of the cable is wound around the winding roller 147 and then sequentially passes through the first sleeve 141 and the second sleeve 142. The second rotating shaft 146 and the winding roller 147 are disposed to enable the cable extending from the motor cylinder 11 to automatically retract into the accommodating cavity 111 after the cable extending from the accommodating cavity 111 extends from the motor cylinder 11.

It should be noted that, the cable with a certain length is usually wound around the winding roller 147 for one to one and a half turns, that is, the cable starts from one side of the winding roller 147 and exits from the other side of the winding roller 147 in a loose state after being wound for one or a half turn. Since the torsion spring is disposed on the second rotating shaft 146, when the cable is pulled, the portion of the cable in the accommodating chamber 111 is changed from a slack state to a tight state, and the winding roller 147 is rotated by a certain angle. In this way, it is ensured that the cable above the accommodating cavity 111 is tightened, and the cable below the connector 112 in the accommodating cavity 111 is not tightened (unstressed), so that the cable below the connector 112 is sufficiently protected from being pulled.

When the cable is not stressed, the torsion spring drives the winding roller 147 to rotate and return to the original position, so that the cable in the accommodating cavity 111 has partial redundant length, and the cable is continuously kept in a relative loose state. Therefore, the cable protection mechanism can avoid the situations that the cable is pulled to loosen the joint and the cable skin is abraded and broken to a certain extent.

The lower end of the transmission shaft 121 extends into the base 13, and the lower end of the transmission shaft 121 is provided with a brush 151 for cleaning the filter screen 131. The brush 151 can rotate along with the transmission shaft 121 to clean the sand and mud with smaller volume on the filter screen 131, so as to prevent the filter screen 131 from being blocked.

As shown in fig. 1, a fender 132 is attached to the base 13 in an inclined manner, and the fender 132 is disposed close to the screen 131. The mud guard 132 can prevent mud blocks with larger volume from being close to the filter screen 131 to prevent the filter screen 131 from being blocked,

the lower end of the transmission shaft 121 is sleeved with a connecting sleeve 152, and the connecting sleeve 152 is in transmission connection with the transmission shaft 121. The connection sleeve 152 is fixedly provided with a connection plate 153, and the brush 151 is fixed on the connection plate 153 to facilitate the installation of the brush 151.

A transmission sleeve 154 is fixed on the transmission shaft 121, the transmission sleeve 154 is positioned above the connecting sleeve 152, a limit nut 155 is connected to the transmission shaft 121 through a thread, and the limit nut is positioned below the connecting sleeve 152. The driving sleeve 154 is fixedly provided with a driving block 156, and the connecting sleeve 152 is provided with a notch matched with the driving block 156. When the transmission shaft 121 rotates, the transmission sleeve 154 can be driven to rotate, the transmission sleeve 154 drives the connection sleeve 152 to rotate through the transmission block 156, and the connection sleeve 152 drives the brush 151 to rotate. The installation and replacement of the connecting sleeve 152 are facilitated due to the arrangement of the limiting screw position.

As shown in fig. 1, the lower end of the connecting plate 153 is wedge-shaped to facilitate the operator to screw the limit screw.

The base 13 is connected to the pump body 12 by bolts 133 to facilitate the installation or replacement of the connection sleeve 152 after the base 13 is removed.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and those skilled in the art can make various modifications and changes, and the embodiments of the present invention and features of the embodiments can be arbitrarily combined with each other without conflict. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
