Upward and downward drainage device floating on water surface

Abstract

The invention discloses a top-to-bottom drainage device floating on the water surface, which comprises a floating raft. A first installation box is fixedly installed on the bottom surface of the floating raft. A submersible sewage pump is installed inside the installation box. There is a water inlet; the top surface of the floating raft is fixed with a second installation box, and the control device is installed inside the second installation box; the four corners of the bottom surface of the floating raft are provided with supporting devices, and the supporting devices include casings and second support rods. One end is fixedly connected with the floating raft, the other end of the casing is socketed with the second support rod, and a touch switch is installed on the top of the inner cavity of the casing, and the control device is connected with the submersible sewage pump through the touch switch. When the second support rod hangs down freely , the top of the second support rod is not in contact with the touch switch. The invention changes the problem that the submersible pump is placed in the water pit for a long time, which leads to the damage of the water pump, and is easy to operate and easy to use without manual operation.

Description

technical field [0001] The invention relates to the technical field of drainage devices, in particular to a top-down drainage device floating on the water surface. Background technique [0002] In the drainage of mining areas and underground tunnel construction, the submersible pump is installed at the bottom of the sump. After a long time, some sludge will be deposited around the pump. The water discharged by the sewage pump is becoming more and more turbid, and in the end it is almost all pumping sludge, which causes the submersible sewage pump to pump sludge for a long time and overload the work, causing the motor to heat up and be burned. For this reason, we propose a kind of device that floats on the water surface and drains water from top to bottom. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a device that floats on the water surface and drains water from top to bottom.
