Description

Technical Field

[0001] This utility model relates to the field of power distribution room inspection, specifically to a power distribution room inspection and detection device. Background Technology

[0002] A power distribution room is an indoor electrical distribution facility with low-voltage loads, primarily supplying power to low-voltage users. In areas with high electricity demand, multiple power distribution rooms are typically set up to meet the power supply and equipment operation requirements. These rooms autonomously distribute power from their distribution systems to different areas or equipment within the region, ensuring a stable power supply to each area and device. When a factory has a large number of power distribution rooms, manual inspection would significantly reduce efficiency. Therefore, power distribution room inspection robots have emerged. These robots automatically complete regular inspections of power distribution rooms according to pre-set inspection paths, greatly improving inspection efficiency compared to manual inspections.

[0003] However, current power distribution room inspection robots typically only monitor equipment and environmental data within the power distribution room. For example, patent CN221614696U discloses a comprehensive power distribution room monitoring system based on a data visualization platform, including an automatic inspection robot, a power distribution cabinet, and a remote monitoring system. The power distribution cabinet is equipped with a volume detector, temperature and humidity sensor, and smoke sensor, and features a digital display for easy data reading by the robot. The remote monitoring system uses a client installed on a computer, allowing real-time monitoring via the robot's camera, storing daily inspection records, generating reports, and remotely executing inspection tasks. This invention upgrades and modifies the power distribution cabinet, installing multiple sensors inside. These sensors convert analog signals into digital signals, which are then read by the robot's camera and uploaded to the monitoring platform. The robot also has an infrared thermal imaging camera; when the temperature inside the cabinet is abnormal, it promptly notifies staff via SMS and issues an alarm on the monitoring platform, significantly reducing the accident rate. However, the thermal imaging camera and conventional camera of the inspection robot disclosed in this patent cannot be adjusted as needed; they can only be used to collect images of power distribution equipment or read the values ​​of instruments on the power distribution cabinet, and their functions are relatively limited.

[0004] Therefore, given the current problem that the cameras of power distribution room inspection robots cannot be adjusted as needed, resulting in relatively limited functionality, developing a power distribution room inspection device with an adjustable pitch angle for a visible light camera is a technical problem that urgently needs to be solved. Utility Model Content

[0005] The purpose of this invention is to provide a power distribution room inspection and testing device to solve the problem that the existing power distribution room inspection robots cannot adjust their cameras as needed, resulting in relatively limited functionality.

[0006] To solve the above-mentioned technical problems, this utility model provides a power distribution room inspection and detection device, including a device body, a walking mechanism installed at the bottom of the device body, and an image acquisition unit installed at the top of the device body through a height adjustment mechanism;

[0007] The height adjustment mechanism is equipped with a mounting base at the top. The image acquisition unit includes a visible light camera and a thermal imaging camera. The visible light camera is mounted on one side of the mounting base via a first pitch angle adjustment mechanism, and the thermal imaging camera is mounted on the other side of the mounting base via a second pitch angle adjustment mechanism. The front end of the visible light camera is equipped with a supplementary light and an ultraviolet light.

[0008] The walking mechanism, height adjustment mechanism, first pitch angle adjustment mechanism, second pitch angle adjustment mechanism, supplementary light, and ultraviolet light are respectively connected to the output terminal of the controller installed in the main body of the device.

[0009] Furthermore, the device body is equipped with a UWB navigation module that is connected to the input signal of the controller; the bottom of the device body is equipped with an electronic tag reader that is connected to the input signal of the controller and is used to read electronic tags set on the inspection path.

[0010] Furthermore, a lidar for detecting obstacles is installed on the front or top of the device body, which is connected to the input signal of the controller.

[0011] Furthermore, the mounting base is equipped with a microphone that is connected to the input signal of the controller and is used to collect the sound signal of the scene to be tested.

[0012] Furthermore, the device body is equipped with an environmental information monitoring module, which includes a temperature and humidity detection unit, a smoke detection unit, and a gas composition detection unit that are connected to the input signal of the controller.

[0013] Furthermore, the gas composition detection unit includes an SF6 gas sensor and a CO gas sensor.

[0014] Furthermore, the first pitch angle adjustment mechanism includes a first motor fixedly installed at one end of the mounting base. The output shaft of the first motor extends out of the mounting base and is connected to a visible light camera. The visible light camera rotates with the first motor to change the pitch angle for image acquisition.

[0015] Furthermore, the second pitch angle adjustment mechanism includes a second motor fixedly mounted on the other end of the mounting base. The output shaft of the second motor extends out of the mounting base and is connected to the thermal imaging camera. The thermal imaging camera rotates with the second motor to change the pitch angle for image acquisition.

[0016] Furthermore, the height adjustment mechanism is an electric lifting rod, one end of which is fixedly connected to the top of the device body, and the mounting base is fixedly installed on the other end of the electric lifting rod.

[0017] Furthermore, a collision protection strip is provided on the front side of the device body.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. By setting up a first pitch angle adjustment mechanism and a second pitch angle adjustment mechanism, the image acquisition pitch angle of the visible light camera and the thermal imaging camera can be adjusted respectively. The pitch angle adjustment mechanism, together with the height adjustment mechanism, enables the visible light camera and the thermal imaging camera to acquire images of power distribution equipment at different heights and positions, thereby improving the adaptability of the cameras.

[0020] 2. By setting up supplementary lighting, the visible light camera can be illuminated in low-light environments to ensure that it can capture clear images.

[0021] 3. By setting up ultraviolet lamps, the visible light camera is adjusted to face the ground while the device moves, and the ultraviolet lamps are turned on. This allows the visible light camera to capture images of the ground in the detection area illuminated by the ultraviolet lamps, which helps to determine whether there is rat activity based on the presence of any dots in the ground images.

[0025] like Figure 1The power distribution room inspection and testing device shown includes a device body 1, a walking mechanism 102 installed at the bottom of the device body 1, and an image acquisition unit installed at the top of the device body 1 via a height adjustment mechanism.

[0026] The height adjustment mechanism has a mounting base 3 on top. The image acquisition unit includes a visible light camera 4 and a thermal imaging camera 5. The visible light camera 4 is mounted on one side of the mounting base 3 via a first pitch angle adjustment mechanism, and the thermal imaging camera 5 is mounted on the other side of the mounting base 3 via a second pitch angle adjustment mechanism. The visible light camera 4 is used to acquire images and / or instrument values ​​on the power distribution cabinet, while the thermal imaging camera is used to convert the invisible infrared energy emitted by the power distribution equipment into visible thermal images, and then use different colors to represent different temperatures of the measured power distribution equipment. The height adjustment mechanism can automatically adjust the camera to adapt to the corresponding height according to the image acquisition point height. The first and second pitch angle adjustment mechanisms can adjust the image acquisition pitch angle of the visible light camera 4 and the thermal imaging camera 5 respectively. The pitch angle adjustment mechanism works in conjunction with the height adjustment mechanism to enable the visible light camera 4 and the thermal imaging camera 5 to acquire images of power distribution equipment at different heights and positions, improving the adaptability of the cameras.

[0027] The visible light camera 4 is equipped with a supplementary light 401 and an ultraviolet light 402 at its front end. The supplementary light 401 provides illumination for the images captured by the visible light camera 4 in low-light environments, ensuring that the visible light camera 4 can capture clear images. Furthermore, during the device's movement, the first pitch angle adjustment mechanism can be used to adjust the visible light camera 4 to face the ground, while simultaneously turning on the ultraviolet light 402. This allows the visible light camera 4 to capture images of the ground in the detection area illuminated by the ultraviolet light 402, which helps in subsequent analysis of the ground image to determine the presence of mouse activity.

[0028] The walking mechanism 102, the height adjustment mechanism, the first pitch angle adjustment mechanism, the second pitch angle adjustment mechanism, the supplementary light 401, and the ultraviolet light 402 are respectively connected to the controller installed in the main body 1 of the device.
