A cleaning component 7 is set in the inner cavity of the water inlet pipe 9. A drain pipe 10 is fixedly installed at the other end of the pump body 8. The other end of the drain pipe 10 penetrates the inner cavity sidewall of the cavity.

[0030] The reciprocating assembly 6 includes a drive motor 61 fixedly installed on the other side of the inner cavity of the fixed groove 3 near the middle position, and a reciprocating lead screw 62 fixedly installed on the power output shaft end of the drive motor 61. One end of the reciprocating lead screw 62 is rotatably connected to the inner cavity sidewall of the fixed groove 3. A lead screw nut 63 is movably sleeved on the outer periphery of the reciprocating lead screw 62 near one end, and a bent rod 64 is fixedly installed on the top of the lead screw nut 63. The front side of the bent rod 64 movably penetrates the inner cavity sidewall of the water storage port. A connecting rod 66 is provided on the front side of the movable block 65. A connecting block 67 is fixedly installed on the front end of the connecting rod 66. Several cleaning blocks 68 are provided at the bottom of the connecting block 67.

[0031] Specifically, when the filter screen 5 becomes clogged, the reciprocating assembly 6 can cause the screw nut 63 on the outer periphery of the movable reciprocating screw 62 to move back and forth, thereby causing the cleaning block 68 located on top of the filter screen 5 to move back and forth, which can clean the impurities on the filter screen 5, prevent it from becoming clogged, avoid the formation of water accumulation in the civil defense project, which would affect its normal use, and facilitate the subsequent drainage of rainwater.

[0037] Specifically, when it is necessary to clean the water inlet, the T-shaped lever 654 can be pulled to move the end of the T-shaped lever 654 away from the inner cavity of the adjacent limiting blind hole 655. Then, the connecting block 67 is flipped to 90 degrees and the T-shaped lever 654 is inserted into the inner cavity of the adjacent limiting blind hole 655, which can limit the rotation position of the connecting block 67.

A controller 12 is fixedly installed at the bottom of the inner cavity near the rear side. A storage battery 13 is fixedly installed at the bottom of the inner cavity near the other side. All liquid level sensors 11 are electrically connected to the controller 12.

[0039] Specifically, when the water level in the water storage port reaches the highest liquid level sensor 11, the pump body 8 can be started by the controller 12 to discharge the rainwater in the water storage port.

[0042] Example 2

[0043] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 3 and Figure 7The cleaning component 7 includes a protective net 71 fixedly installed in the inner cavity of the water inlet pipe 9 and a crossbar 72 that moves through the protective net 71. A turbine 73 is fixedly sleeved on the outer periphery of the crossbar 72 near the other end, and a cleaning brush 74 is fixedly installed on one end of the crossbar 72. The cleaning brush 74 is fitted to the protective net 71.

[0044] Specifically, during the drainage process, the turbine 73 can be rotated in conjunction with the cleaning component 7, and the cleaning brush 74 fixed at the end of the crossbar 72 can be rotated in conjunction with the crossbar 72, which can clean the protective net 71, prevent impurities from clogging the protective net 71, and improve the efficiency of subsequent drainage.

[0045] A support block 721 is rotatably connected to the outer periphery of the crossbar 72 near the other end, and the top of the support block 721 is fixedly connected to the top of the inner cavity of the water inlet pipe 9.

[0046] Specifically, the crossbar 72 can be supported by setting the support block 721.

[0047] Working Principle: In use, the drainage tank 1 is installed under the drainage well. Rainwater passes through the well cover 2 and the filter screen 5 into the inner cavity of the water storage port. A liquid level sensor 11 monitors the water level in the inner cavity of the water storage port in real time. When the water level reaches a certain level, the controller 12 starts the pump body 8. The pump body 8 discharges the rainwater from the inner cavity of the water storage port through the inlet pipe 9. During the process of rainwater entering the water storage port, when it is necessary to clean the filter screen 5, the drive motor 61 can be started. The rotation of the drive motor 61's power output shaft drives the reciprocating screw 62 fixed to the end of the drive motor 61's power output shaft to rotate, allowing the screw to move around the outer periphery of the reciprocating screw 62. The screw nut 63 reciprocates under the limiting of the limiting block 631 and the limiting rod 632. Under the connection of the bent rod 64, the movable block 65 and the connecting block 67, the cleaning block 68 can reciprocate to clean the impurities on the top surface of the filter screen 5, which can prevent it from clogging and avoid affecting the subsequent use of the civil defense project. During the process of draining rainwater from the water storage port, the protective net 71 is set in the inner cavity of the water inlet pipe 9 to protect the pump body 8 during use. Under the impact of the water flow, the turbine 73 can rotate. Under the transmission of the cross rod 72, the cleaning brush 74 can rotate to clean the surface of the protective net 71, preventing the protective net 71 from clogging and affecting the subsequent drainage efficiency.

[0048] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
