Description

Technical Field

[0001] The utility model relates to the technical field of substation inspection, in particular to an intelligent substation inspection vehicle. Background Technique

[0002] With the rapid development of China's economy and the continuous improvement of residents' living standards, the load of the power system is increasing day by day. How to ensure the reliability of residents' power consumption has become an urgent problem for the power system. Ensuring the normal operation of substation equipment is an important link in ensuring power consumption reliability. In order to adapt to the increasingly developing power system, the voltage level and capacity of substations have increased, and the safe and stable operation of substations has a long way to go.

[0003] In traditional inspection technologies, maintenance personnel need to hold an infrared thermometer and perform infrared temperature measurement on substation equipment twice a day to determine whether there are any abnormalities. This kind of manual inspection has problems such as high labor intensity, low work efficiency, and high management costs.

[0004] With the development of science and technology, currently domestic substations gradually adopt ground mobile inspection vehicles for inspection. The inspection vehicle drives an infrared thermometer to move to perform infrared temperature measurement on substation equipment. In addition, in order to improve the practicability of the mobile inspection vehicle and expand the temperature measurement range of the infrared thermometer at the detection points, a lifting mechanism, an angle adjustment mechanism, and a rotation mechanism are set to lift, tilt, and horizontally adjust the main body of the infrared thermometer. However, the coordinated control of multiple mechanisms will lead to cumbersome operation of the infrared thermometer. Therefore, we propose an intelligent substation inspection vehicle.

The wireless data transmission module is connected to the infrared temperature sensor through the four ports of RS485A, RS485B, 12V, and GND, and the wireless data transmission module is connected to the storage battery through the two ports of 12V and GND.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0021] Please refer to Figures 1-4, the present utility model provides an intelligent substation inspection vehicle, including a base 1. At the four corners of the lower surface of the base 1, traveling wheels 2 are provided. A driving mechanism for driving the rotation of the traveling wheels 2 is arranged inside the base 1, enabling the intelligent inspection vehicle to move. The upper surface of the base 1 is connected to a fixed frame 4 through a support rod 3. A first chamber 41 and a second chamber 43 are arranged inside the fixed frame 4. A partition 42 is arranged between the first chamber 41 and the second chamber 43. The left and right ends of the first chamber 41 are open, and the left and right ends of the second chamber 43 are closed. A motor 5 is arranged inside the first chamber 41. The output end of the motor 5 is fixedly connected to a first gear 6. The first gear 6 is meshed with a second gear 7. A support frame 8 is arranged in the middle of the gear shaft of the second gear 7. Through the meshing connection of the first gear 6 and the second gear 7, the motor 5 can drive the support frame 8 to rotate. Two infrared temperature sensors 9 are symmetrically fixed on the support frame 8, and the two infrared temperature sensors 9 respectively face the left and right open ends of the first chamber 41. A guide rod 10 parallel to the gear shaft of the second gear 7 is also arranged on the support frame 8. An arc groove 11 adapted to the end of the guide rod 10 is opened on the front side wall of the first chamber 41. The number of the guide rods 10 and the arc grooves 11 corresponds to the number of the infrared temperature sensors 9 one by one. Pressure sensors 13 are arranged at both ends of the arc groove 11. Springs 12 are connected to the pressure sensors 13. When the guide rod 10 moves to both ends of the arc groove 11, the springs 12 will be compressed, and the compressed springs 12 will apply pressure to the pressure sensors 13. When the pressure sensors 13 detect that the pressure reaches a preset pressure value, the pressure sensors 13 will send the detected pressure signal to a controller. The controller controls the motor 5 to change the rotation direction of the first gear 6. The controller is not shown in the figure, and the controller can be a controller with the model of STM32.

[0022] It should be noted that the intelligent inspection vehicle of the present utility model adopts a navigation and positioning method based on visual detection and recognition of road guiding lines and positioning marks. The navigation marking lines and positioning marks are preset, and the intelligent inspection vehicle automatically identifies the inspection path and detection points through a visible light camera. Among them, the navigation and positioning method of the present application is a prior art, and the specific implementation process will not be elaborated here. When the intelligent inspection vehicle stops at the detection point, the motor 5 can drive the infrared temperature sensor 9 to swing up and down to measure the temperature of the substation equipment on both sides of the infrared temperature sensor 9. Since the infrared temperature sensor 9 swings within a certain angle range, the temperature measurement range of the infrared thermometer 9 at the detection point can be expanded. Specifically, when the pressure sensor 13 monitors that the pressure reaches the preset pressure value, the motor 5 automatically changes the rotation direction of the first gear 6, so that the guide rod 10 moves to one end of the arc groove 11 and then automatically moves in the opposite direction, without manual intervention, reducing the time and effort of manually adjusting the infrared temperature sensor 9; moreover, compared with the prior art, the lifting mechanism, angle adjustment mechanism and rotation mechanism are set to lift, tilt angle adjustment and horizontal angle adjustment of the infrared thermometer main body, the control strategy of the present utility model is simple and effective.

[0023] A wireless data transmission module 14 and a storage battery 15 are arranged in the second chamber 43, and the wireless data transmission module 14 is a LORA wireless module. An interface is arranged on the wireless data transmission module 14, and the interface includes four ports of RS485A, RS485B, 12V and GND. The wireless data transmission module 14 is connected to the infrared temperature sensor 9 through the four ports of RS485A, RS485B, 12V and GND. At the same time, the wireless data transmission module 14 is connected to the storage battery 15 through the two ports of 12V and GND. The wireless data transmission module 14 is also connected to the pressure sensor 13 through the two ports of 12V and GND; since the positive and negative electrodes of the storage battery 15 are connected to the two ports of 12V and GND of the wireless data transmission module 14, the storage battery 15 can supply power to the wireless data transmission module 14, the infrared temperature sensor 9 and the pressure sensor 13 at the same time. The wireless data transmission module 14 is also connected with an antenna 16, and the antenna 16 is fixed on the top wall of the fixed frame 4 through a sucker. Through the antenna 16, the temperature value monitored by the infrared temperature sensor 9 can be conveniently wirelessly sent to the terminal device.
