The working principle is as follows: after the pumping work of double entry pump is accomplished, 11 insidely can remain a large amount of ponding in the second pump case, consequently, the staff starts electric putter 45 when double entry pump is about to finish the work, electric putter 45 drives spliced pole 22 and lifting board 31 and moves down, slot 32 and fore-set 33 of lifting board 31 bottom cooperate until, the motion that resets through damper can effectually exert ascending thrust to lifting board 31 this moment, can be with effort in sprue 41 when lifting board 31 receives thrust, thereby can realize the automatic drainage of water drainage tank 44.
Further, the top outer wall of the connecting disc 25 is fixedly connected with a top column 33, the bottom outer wall of the lifting plate 31 is fixedly connected with a slot 32, the slot 32 and the lifting plate 31 are integrally formed, and the top column 33 is matched with the slot 32 in an inserting mode.
The working principle is as follows: because the springs in the shock-absorbing assembly can reset after the double-suction pump stops working, the jacking column 33 can be subjected to upward jacking force of the springs when the shock-absorbing assembly resets, and the jacking force applied to the jacking column 33 acts on the block 41, thereby rapidly ejecting the blocking block 41, realizing the drainage work of the second pump shell 11, avoiding the situation that parts such as the helical blade 16 and the like are corroded and damaged when being soaked in accumulated water for a long time, when the double suction pump stops draining water and needs to work, the electric push rod 45 is started, the lifting plate 31 and the slot 32 can be driven to move upwards by starting the electric push rod 45, therefore, the top column 33 is separated from the slot 32, the electric push rod 45 drives the lifting plate 31 to move upwards in the working process of the shock absorption assembly, at the moment, the top column 33 cannot be in contact with the slot 32, namely, the top column 41 cannot be continuously opened, and the working stability of the double suction pump is ensured.
Furthermore, the top outer wall of the mounting plate 2 is provided with a through hole 20, and one end of the connecting column 22 penetrates through the through hole 20.
The working principle is as follows: since the connection column 22 passes through the inside of the through hole 20, the connection column 22 can be guided well through the through hole 20.
