Water-getting device with anti-blocking and degritting functions

Abstract

The invention discloses a water-getting device with anti-blocking and degritting functions and relates to the technical field of water-getting devices. The water-getting device comprises a transmission pump box, a driving motor connected with the transmission pump box and a water conveying pipe connected to a water inlet of the transmission pump box. The water-getting device further comprises a filtering box arranged on the water conveying pipe. The filtering box is internally provided with a filtering cartridge capable of sliding from the filtering box, a flow velocity detection mechanism anda filtering cartridge limiting and ejecting mechanism. The filtering cartridge limiting and ejecting mechanism is controlled by the flow velocity detection mechanism and used for locating the filtering cartridge to a position of the water conveying pipe or ejecting the filtering cartridge to slide out of the filtering box for replacement. According to the water-getting device with the anti-blocking and degritting functions, whether the water-getting device is blocked or not can be detected automatically in the process of pumping water; and the filtering cartridge is replaced timely and automatically.

Description

technical field [0001] The invention relates to the technical field of water intake devices, in particular to a water intake device with the function of preventing blocking and removing sand. Background technique [0002] Our country has abundant water resources, especially many lakes and rivers. Using these fresh water resources in nature to irrigate our farmland and engineering construction can save us more drinking water resources, but the water resources in rivers and lakes Lots of gravel and weeds. [0003] The prior art discloses a water intake device with the application number of 201320391376.0, which has the function of anti-blocking and sand removal. The sawtooth-shaped arrangement of the sloping plate and the vertical plate has a water inlet hole on the vertical plate, and the direction of water flow is consistent with the inclination direction of the zigzag. They are sucked together and used after passing through the filter device, and the filter device is easi...
