Underwater monitoring method and device of hydraulic gripping beam

Abstract

The invention discloses an underwater monitoring method and device of a hydraulic gripping beam. According to the method, a high-definition camera is mounted on the hydraulic gripping beam, the pin penetrating and pin disengaging process of the hydraulic gripping beam can be observed through the high-definition camera, hence, the operation safety of the hydraulic gripping beam is improved, it is guaranteed that the problems of a product of a hydraulic metal structure in the operating process can be timely discovered and timely handled, and loss is reduced. The device comprises the high-definition camera mounted on the hydraulic gripping beam. The high-definition camera is connected to a liquid crystal display and a hard disk video which are arranged inside a monitoring chamber through signal cables. By means of the underwater monitoring method and device of the hydraulic gripping beam, the pin penetrating and pin disengaging process of the hydraulic gripping beam can be observed, hence, the operation safety of the hydraulic gripping beam is improved, it is guaranteed that the problems of the product of the hydraulic metal structure in the operating process can be timely discovered and timely handled, and loss is reduced.

Description

technical field [0001] The invention relates to a hydraulic grabbing beam, in particular to an underwater monitoring method and device for a hydraulic grabbing beam. Background technique [0002] With the continuous development of my country's water conservancy and hydropower projects, the application of hydraulic grab beams in water conservancy and hydropower projects is also increasing, especially for the opening and closing of large and medium-sized gates. When the mobile gate hoist is used to operate the multi-hole gate or the gate is lifted under deep water, it is more suitable to use the hydraulic grab beam. When the gate opening size is large and the gate is difficult to lift as a whole, the gate can be made into the form of a stacked beam gate. Use the hydraulic grab beam to lift in sections. [0003] The monitoring of the hydraulic grab beam refers to the monitoring of the process of the grab beam falling in place and the pins being put on and off. At present, the ...

Problems solved by technology

[0003] The monitoring of the hydraulic grab beam refers to the monitoring of the process of the grab beam falling in place and the pins being put on and off. At present, the most widely used hydraulic grab beam monitoring system adopts an external type, which can only provide a signal for the operator of the door machine, and cannot be real-time and dynamic. The entire movement process of the earth observation hydraulic grabbing beam shifting axis cannot give the operator an intuitive signal display state. Once an accident occurs, it is completely judged by human experience; due to the use of an external type, the reliability and anti-interference of the signal cannot be reliably obtained. The guarantee, and because the grabbing beam is operated in deep water, the underwater conditions are complex, it is inevitable that obstacles will be encountered, resulting in damage to the signal device
