Description

Technical Field

[0001] The utility model relates to the technical field of liquid level gauges, in particular to an inner wall cleaning device for a magnetic liquid level gauge. Background Technique

[0002] The magnetic liquid level gauge is installed on the extension pipe outside the barrel tank, and the liquid level inside the barrel tank can be clearly known by the flap indicator. A magnetic switch can also be installed outside the bypass pipe as an electrical contact signal output, or a liquid level transmitter can be installed for long-distance liquid level signal transmission and liquid level control. This liquid level gauge is a reliable safety instrument. The liquid level gauge works based on the buoyancy principle and the magnetic coupling principle. When the liquid level in the measured container rises or falls, the float in the main pipe of the liquid level gauge also rises or falls accordingly. The permanent magnet in the float is transmitted to the on-site indicator through magnetic coupling, driving the red and white turning columns to flip 180°. When the liquid level rises, the turning column turns from white to red; when the liquid level drops, the turning column turns white. The actual height of the medium liquid level in the container is at the red and white boundary of the indicator, thus realizing liquid level indication. After the magnetic liquid level gauge has been used for a long time, some substances will adhere to the inner wall of the pipe where the float is located, which will affect the subsequent normal lifting and lowering of the float. It is necessary to clean the pipe fittings where the float is located regularly. The cleaning effect of the existing cleaning tools is poor, the efficiency is low, it is inconvenient to use, time-consuming and laborious, and it is not easy to be popularized and applied. Content of the Utility Model

[0003] To solve the technical problems in the background technique, the utility model proposes an inner wall cleaning device for a magnetic liquid level gauge.

[0004] An inner wall cleaning device for a magnetic liquid level gauge proposed by the utility model includes a straight pipe, a cleaning head is installed at the top end of the straight pipe, multiple groups of rhombic telescopic frames are installed on the side wall of the cleaning head, and a limiting frame is installed at the end of the rhombic telescopic frame; a turntable is rotatably connected to the top of the cleaning head, multiple groups of brushes are installed on the side wall of the turntable, and a motor is installed in the cleaning head, and the motor is used to drive the turntable to rotate.

[0005] Preferably, the rhombic telescopic frame is formed by hinging the heads and tails of four groups of equal-length connecting rods, one of its angles is installed on the side wall of the cleaning head, and a spring is connected between this angle and its opposite angle.

[0006] Preferably, the rhombic telescopic frames are centrally distributed on the cleaning head, and at least three groups of rhombic telescopic frames are provided.

[0007] Preferably, a water cavity is built in the cleaning head, multiple groups of nozzles are opened on the side wall of the cleaning head, each group of nozzles is communicated with the water cavity, the straight pipe is communicated with the water cavity, and a water pipe is connected to the tail end of the straight pipe.

[0008] Preferably, a handle is installed outside the tail end of the straight pipe.

[0009] Preferably, a plurality of groups of pulleys are installed on the limiting frame.

[0010] In the present utility model, a cleaning device for the inner wall of a magnetic liquid level gauge is proposed. After the magnetic liquid level gauge is used for a long time, some residual substances will adhere to the inner wall of the pipe where the float is located, thus affecting the lifting of the float. It is necessary to clean it regularly. The straight pipe is inserted into the inner wall of the pipe where the float is located, and is positioned on the inner wall of the pipe by a plurality of diamond-shaped telescopic frames. The motor drives the turntable to rotate, and the inner wall of the pipe is brushed by the brush. The diamond-shaped telescopic frame can change the distance between the limiting frame and the side wall of the cleaning head by compressing the spring. When the cleaning head extends into the pipe, the spring rebounds, so that the limiting frame is positioned on the inner wall of the pipe, and the cleaning head is located on the axis of the pipe. At this time, by changing the position of the cleaning head through the straight pipe, the inner wall of the pipe can be cleaned by the brush. Water is guided into the straight pipe through a water pipe, enters the water cavity, and is then sprayed on the inner wall of the pipe through a nozzle. This water can be a detergent to enhance the cleaning effect. Combined with the brush, it further plays the role of brushing. The handle is convenient for holding by hand to control the movement of the cleaning head. The pulley can reduce the frictional resistance, make the cleaning head move more smoothly on the inner wall of the pipe, with high cleaning efficiency, time-saving and labor-saving, and is easy to be popularized and applied.
