Magnetic type hydraulic jet descaling device and control method thereof

Abstract

The invention discloses a magnetic type hydraulic jet descaling device and a control method thereof. The magnetic type hydraulic jet descaling device comprises an outer shell and a controller, a waterstorage box body is arranged on the middle portion of the outer shell, a water inlet of the water storage box body is connected with a jet pump, a plurality of jet channels leading to the outer portion of the bottom of the outer shell are distributed at the bottom of the water storage box body, and the jet channels are provided with corresponding solenoid valves. A controller controls the jet pump to provide jet water for the water storage box body when the jet pump is opened. The opening and closing of each solenoid valve is controlled so as to open or close the corresponding jet channel toachieve the movement of the device or dirt removal. The magnetic type hydraulic jet descaling device is further provided with an ultrasonic rangefinder to detect the distance from a metal plate, the thickness of the dirt is determined and information is fed back the to the controller. An iron core wound with a coil is arranged on the upper portion in the outer shell. The controller controls the current intensity flowing through the coil to realize the locking and releasing of positions of the device. The magnetic type hydraulic jet descaling device can avoid the impact on the environment in the traditional chemical descaling process, and the device is simple and light in structure and flexible in movement.

Description

technical field [0001] The invention relates to the technical field of ship surface maintenance, in particular to a magnetic hydraulic jet descaling device and a control method thereof. Background technique [0002] With the rapid development of our country's economy, the number of trades between countries continues to increase, thus giving birth to ships with larger and larger tonnages. In addition, with the continuous improvement of people's economic level, people's environmental awareness continues to increase, which also leads to the continuous deepening of people's environmental concept in life and work, and requires environmental harmlessness for the items they can touch. However, for our rapidly developing ocean shipping industry, the simplified schematic diagram of the position of solid dirt on the surface of the ship is as follows figure 1 However, it is difficult to remove it in an environmentally friendly and simple way. There are major problems in the existing d...

AI Technical Summary

Problems solved by technology

[0003] 1) The existing chemical descaling has a great impact on the environment of the surrounding waters and will cause certain water pollution problems;

[0004] 2) The existing physical descaling equipment is relatively complicated, and the decontamination tools are bloated and costly;

[0005] 3) Many of the existing descaling methods are manual operations with a low degree of automation and excessive labor costs
