Description

Technical Field

[0001] The present application relates to the technical field of robot equipment, and in particular to an unmanned substation inspection robot. Background Art

[0002] Substations are places where voltage and current are converted in power systems, and are important equipment in the production, transmission, distribution and use of electricity. In order to ensure the safe and stable operation of substations, regular inspections are essential. With the development of social economy and the advancement of science and technology, artificial intelligence has begun to be widely used in the industrial field, and substation inspection robots have also emerged. However, during the long-term inspection process of the existing substation inspection robots, the guide wheels thereon are very likely to wear due to the frequent braking and running, which in turn causes the positioning accuracy of the inspection robot to deteriorate, and the accuracy of substation inspection becomes low. In addition, the existing inspection robots all perform inspection operations according to preset inspection trajectories, resulting in a long inspection cycle per week. When some electrical equipment with a high failure rate fails during this process, timely feedback cannot be provided, which poses a great safety hazard, and the stability and reliability are poor.

[0003] Therefore, there is an urgent need for an inspection robot for substations to solve the defects of the above-mentioned existing inspection robots during actual use. Summary of the invention

[0004] The present application proposes an unmanned substation inspection robot, which has the function of effectively reducing the wear problem of the guide wheel caused by frequent braking and operation, so that the inspection robot can maintain a high positioning accuracy and has a high accuracy in substation inspection. At the same time, it can promptly inspect and feedback abnormal electrical equipment, and has the advantages of high safety and reliability. It is used to solve the problem that the existing substation inspection robots are prone to wear due to the frequent braking and operation during long-term inspection operations, which in turn causes the positioning accuracy of the inspection robot to deteriorate and the accuracy of substation inspection to decrease. In addition, the existing inspection robots all perform inspection operations according to preset inspection trajectories, resulting in a long inspection cycle. When some electrical equipment with a high failure rate fails during this process, it is impossible to provide timely feedback, which poses a major safety hazard.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: an unmanned substation inspection robot, comprising a hanging rail arranged in sequence according to the substation and fixedly installed on the top of the factory building, the bottom of the outer surface of the hanging rail is movably connected with a support frame with the inspection robot fixedly installed on the bottom end, a group of magnetic plates are respectively provided on both sides of the outer surface of the hanging rail, and electromagnetic devices are provided on both sides of the outer surface of the hanging rail and directly above the electrical equipment of the substation, and a continuous linear structure is formed between the magnetic plates and the electromagnetic devices. A group of magnetic blocks corresponding to the positions of the magnetic plates and the electromagnetic devices are respectively provided on both sides of the top of the inner cavity of the support frame, and the magnetic poles of the magnetic blocks repel each other with the magnetic poles of the magnetic plates and the electromagnetic device at the beginning, and then, under the action of magnetic repulsion at the beginning, the support frame can be in a suspended arrangement state, and when the support frame moves along the trajectory of the hanging rail, the friction resistance between them can be effectively reduced, a reducer is fixedly installed in the middle of the inner cavity of the support frame, and a guide wheel whose outer surface contacts the bottom end of the hanging rail is provided on the output shaft of the reducer.

[0006] Furthermore, a conductive ring is provided on the outer surface of the guide wheel, and a carbon bar corresponding to the position of the conductive ring is fixedly installed in the middle of the bottom end of the hanging rail, an electrical connection is formed between the conductive ring, the carbon bar and the reducer, and the reducer is connected when the conductive ring and the carbon bar are in contact, and the electrical connection to the reducer is cut off when the conductive ring and the carbon bar are separated, so that when the inspection robot on the support frame performs inspection operations on the substation equipment at the corresponding position, the reducer can be automatically shut down to reduce its energy consumption during operation.

[0007] Furthermore, the abnormal signal feedback system on the substation equipment transmits the abnormal signal to the feedback system of the electromagnetic device on the hanging rail when an abnormality is detected in the substation equipment, and reversely connects the electromagnetic device at the corresponding position to generate magnetic poles that attract the magnetic block, while the magnetic poles of other groups of electromagnetic devices on the hanging rail and located on the preset inspection trajectory remain unchanged, so that the inspection robot on the support frame is preferentially moved to the top of the substation equipment where the abnormal signal occurs, so as to carry out patrol inspection on it.

[0008] Furthermore, the inspection robot transmits the data of the substation equipment inspected by the inspection robot in two parts. The inspection data of the substation equipment without problems is transmitted to the data storage device, thereby avoiding the equipment jamming problem caused by excessive data storage volume. The inspection data of the substation equipment with problems is transmitted to the detection equipment in the hands of the maintenance personnel, so that the abnormal situation can be promptly delivered to the maintenance personnel for analysis and discussion to come up with a solution, and the time required for handling abnormal situations of the substation equipment is effectively reduced.

[0009] Furthermore, a first conductive block is provided on one side of the outer surface of the hanging rail and at a position corresponding to the electromagnetic device, and a second conductive block is fixedly installed on one side of the inner wall of the support frame, and an electrical connection is formed between the first conductive block, the second conductive block and the electromagnetic device. Therefore, when the support frame moves along the track of the hanging rail, when the first conductive block comes into contact with the second conductive block, the electromagnetic device is automatically triggered to generate magnetic poles that attract the magnetic block, and the inspection robot on the support frame is activated.

[0010] Furthermore, the lower half of the cross section of the hanging rail is set as an isosceles triangle structure, so that the support frame is suspended and the clamped support frame is automatically calibrated and balanced under the influence of gravity.

[0011] The beneficial effects of the present invention are as follows: 1. The present application provides an unmanned substation inspection robot. With respect to the arrangement of a support frame and a structure thereon, under the action of magnetic repulsion, the support frame can be initially suspended, and when the support frame moves along the trajectory of a hanging rail, the friction resistance therebetween can be effectively reduced. After the support frame moves to a specific position, the electromagnetic device is reversely connected to generate magnetic poles that attract the magnetic block, and force the support frame and the inspection robot thereon to move downward. While braking the support frame, the outer surface of the guide wheel is separated from the bottom end of the hanging rail, thereby effectively reducing the wear of the guide wheel caused by frequent braking and operation, so that the inspection robot can maintain a high positioning accuracy and has a high accuracy for substation inspection.

[0012] 2. The present application provides an unmanned substation inspection robot. With respect to the setting of the system structure of the inspection robot, the inspection data of the substation equipment without problems can be transmitted to the data storage device, thereby avoiding the equipment jamming problem caused by excessive data storage. The inspection data of the substation equipment with problems can be transmitted to the detection equipment in the hands of the maintenance personnel, so that the abnormal situation can be promptly delivered to the maintenance personnel for analysis and discussion to come up with a solution, and the time required for handling abnormal situations of the substation equipment can be effectively reduced.
