Device and method for inspecting closed space of thermal power unit

Abstract

The invention discloses a device and a method for inspecting the closed space of a thermal power unit. The device includes two inspection trolleys connected by a flexible connector. Each inspection trolley is internally equipped with an inspection execution unit which includes an image acquisition module, a lighting module, an action control motor, a motion controller, a wireless communication module and a battery module. The method includes the following steps: placing the two inspection trolleys on the ground of the closed space of a thermal power unit and connecting the two inspection trolleys to a control end through a wireless communication network; carrying out light fill-in through the lighting modules and collecting inspection images through the image acquisition modules accordingto the command of the control end, and uploading the inspection images to the control end; and making the device run in different running modes according to the command of the control end to adapt tothe small-diameter closed pipe space of the thermal power unit. The device has strong obstacle crossing ability and strong field adaptability. The inside of the small-diameter closed pipe space of a thermal power unit can be quickly and efficiently inspected.

Description

technical field [0001] The invention relates to an inspection technology for a confined space of a thermal power unit, in particular to a device and method for inspection of a confined space of a thermal power unit, which can realize internal detection in a confined space with a small pipe diameter of the thermal power unit. Background technique [0002] In order to ensure the safe and stable operation of electric power production, it is necessary to carry out planned inspection and maintenance of electric power equipment on a regular basis. Due to the limitation of the detection environment and detection conditions, it often consumes a lot of manpower and maintenance in the maintenance of some electric power operation equipment. After the material resources, there are still detection blind spots, which bring security risks to the equipment. For example, in the regular maintenance of thermal power units, the interior of many headers and pipes are also key inspection objects....

AI Technical Summary

Problems solved by technology

Since the endoscope hose is operated manually, the length and angle of the probe cannot be controlled, so it is difficult to determine the specific position of the detection probe in the inner room; secondly, the header of the thermal power unit is generally long, and it is often Only the hand hole at one end of the header is cut for detection, so it is impossible to detect the entire inside of the header, and there are large observation blind spots; in addition, because some headers do not have a single entrance and exit, the connection parts such as tees in the header When inspecting the inner wall, the endoscopic inspection method currently used has been unable to complete the inspection work as required
