Abstract

The dust recovery device of the valve tower cleaning tool includes a telescopic rod and a dust processing device. One end of the telescopic rod is equipped with a dust collection device. The dust collection device includes a dust recovery cover. The dust recovery cover is an inverted hemispherical shell. The upper part is hinged with the telescopic rod, and electric push rods and springs are respectively installed on both sides of the dust recovery cover. In the present invention, several distance measuring sensors are installed on the bottom of the dust recovery cover. The distance between the tower and the distance signal is converted into an electrical signal and transmitted to the controller. The controller controls the extension or contraction of the electric push rod according to the electrical signal, so that the distance between multiple distance measuring sensors and the valve tower is finally the same.

Description

technical field [0001] The invention relates to a recovery device, in particular to a dust recovery device of a valve tower dust cleaning tool. Background technique [0002] The valve tower cleaning tool of DC power transmission converter valve is a special tool for cleaning valve tower of DC converter station. Among them, the dust recovery device mainly includes an anti-static vacuum cleaner, a retractable handheld pole, and a dust recovery cover. After the valve tower cleaning tool blows up the dust, the suction generated by the anti-static vacuum cleaner is used to connect with a retractable hand-held rod to generate negative pressure near the mouth of the dust recovery hood, and the surrounding dust is collected in it to prevent secondary Pollution. The dust recovery cover of the existing HVDC converter valve tower cleaning tool cannot swing. When the telescopic rod of the dust recovery cover is not placed properly, the dust recovery cover is likely to have a large gap...
