Inspection device for transformer substation

Abstract

The invention discloses an inspection device for a transformer substation, which improves the protection performance of the whole inspection device, is more flexible in adjustment of a camera, is morereliable in protection of the camera and a mobile vehicle body and improves the durability and the adaptability. The inspection device comprises a mobile vehicle body, wherein a protective frame is arranged outside the mobile vehicle body, driving rear wheels are arranged behind the bottom of the mobile vehicle body, and universal front wheels are arranged in front; a sensor fixing assembly usedfor fixing a sensor is supported in front of the top of the mobile vehicle body through a supporting frame, a three-joint mechanical arm is installed behind the top of the mobile vehicle body, a camera assembly is installed at the tail end of the three-joint mechanical arm, and the bottom of the three-joint mechanical arm is fixed to the top surface of the mobile vehicle body through a fixing table; the three-joint mechanical arm comprises a first joint arm, a second joint arm and a third joint arm; the first joint arm is rotationally connected with the fixing table through a first connectingshaft.

Description

technical field [0001] The invention relates to a substation patrol inspection device, which is specifically used for the patrol inspection of substation equipment. Background technique [0002] Due to its particularity, substations need frequent manual inspections to ensure their safety. Manual patrol inspection is greatly affected by the personnel's physiological and psychological quality, sense of responsibility, external working environment, work experience, and technical level, and there is a possibility of missed inspection and missed discovery. And for the internal defects of the equipment, the operating personnel do not have professional instruments or the accuracy of the instruments is too low, so they cannot be found through simple inspections, such as oil and gas test items exceeding the standard, special parts of the equipment heating, and insulation failures; therefore, more and more Many substations use robot inspection methods. Usually the inspection robot i...

Problems solved by technology

[0004] The applicant found through long-term research on the use of existing inspection robots and the daily operation and maintenance of substations that the cameras of existing inspection robots adopt a fixed structure, especially the height is fixed, and the adjustment structure is limited to the adjustment similar to the pan-tilt In this way, there will be some difficulties for complex on-site working conditions; it needs to be used in occasions where the camera is as close as possible to the equipment, which is not very flexible, and because the camera is as close as possible to the equipment, it will cause damage when the camera is close to the equipment; these equipment generally For equipment with a transparent observation window, the camera needs to stick to the window to view the internal environment of the cabinet and display information;

[0005] On the one hand, the protection of the inspection robot is very important, on the other hand it is also very practical, which can greatly reduce the maintenance cost and improve the service life; not only the close observation protection of the camera is currently flawed, but also the protection of the mobile body itself that the robot moves is currently It is also relatively deficient. The impact will frequently occur around the moving car body. Long-term impacts will cause inevitable damage to the moving car body and shutdown repairs.
