Automatic protection device for movable submersible pump

Abstract

The invention relates to the technical field of hydraulic engineering, and discloses a movable submersible pump automatic protection device which comprises a surge shaft and a submersible pump body, a diversion tunnel is arranged at the bottom of the surge shaft, a mounting plate is fixedly connected to the inner wall of one side of the surge shaft, a sliding groove is formed in one side of the mounting plate, and a movable seat is movably connected into the sliding groove; a floating ball liquid level switch is fixedly connected to one side of the moving seat, a threaded rod is movably connected to the interior of the mounting plate, and the threaded rod is in threaded connection with the moving seat. The submersible pump body can be automatically started and stopped through matched use of the submersible pump body and the floating ball liquid level switch, the using effect of the device is improved, the upper limit and the lower limit of the water level in the surge shaft can be adjusted through matched use of the threaded rod and the movable base, the adjusting effect of the device is improved, and the service life of the device is prolonged. And a sliding ring and a supporting column can be used in cooperation, so that the submersible pump body is supported, and the supporting effect of the device is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering, in particular to a mobile submersible pump automatic protection device. Background technique [0002] Submersible pumps are divided into two types: fixed submersible pumps and mobile submersible pumps, which are widely used in water conservancy projects. Fixed submersible pumps are mainly used in water collection wells, rainwater wells, etc., to remove leaking water or rainwater. During engineering construction, the terrain of the site is often lower than the groundwater level, which is easily affected by seepage water and forms stagnant water, resulting in failure of normal construction. Therefore, submersible pumps are needed for drainage. [0003] The mobile submersible pump is small in size, easy to move, and high in frequency of use, but it cannot self-open and close the protection device as the water level changes, and needs to be opened and closed manually. The task even thr...
