Description

Technical Field

[0001] This utility model relates to the field of insulator testing technology, and in particular to an insulator testing device for outdoor power systems. Background Technology

[0002] Outdoor power system insulator testing devices are key equipment used to diagnose the operating status of insulators and promptly detect defects such as contamination, cracks, and zero insulation (loss of insulation capacity). Existing insulator testing devices can use infrared thermal imagers to detect the temperature of insulators. Normal insulators have a uniform temperature distribution, while inferior insulators will show localized overheating due to increased leakage current, which can be clearly identified in thermal imaging.

[0003] Many insulators in outdoor power systems are located at high positions. When using infrared thermal imagers to inspect high-altitude insulators, it is necessary to use them in conjunction with drones. However, the infrared thermal imagers on existing drones are fixedly installed or fixed with screws. Turning the screws during the disassembly and assembly process is time-consuming, affecting work efficiency and making it inconvenient for later maintenance of the infrared thermal imagers.

[0004] Therefore, those skilled in the art have proposed an insulator testing device for outdoor power systems to solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 and Figure 5 This is the first embodiment of the present utility model. This embodiment provides an outdoor power system insulator detection device, which can achieve the effect of convenient maintenance of infrared detection devices. It includes a drone body 100 and a camera 101 and an infrared detection device 102 installed on the drone body 100.

[0031] It should be noted that the main body of the drone 100 is an existing device, and the specific model and working principle will not be described here. The main body of the drone 100 is controlled by a remote controller, which is also equipped with a display screen for displaying the images captured and detected by the camera 101 and the infrared detection device 102. When the main body of the drone 100 flies to the high insulator of the outdoor power system, the infrared detection device 102 transmits the detected thermal image to the display screen of the remote controller. Normal insulators have a uniform temperature distribution, while inferior insulators will overheat locally due to increased leakage current.

[0032] The quick-release component 200 includes a U-shaped frame 201 mounted on the main body 100 of the UAV. Two sets of movable clamping plates 203 are slidably connected inside the U-shaped frame 201. Side clamping slots 212 connected to the movable clamping plates 203 are provided on both sides of the infrared detection device 102. A rear plate 208 is also mounted on the U-shaped frame 201. A push plate 211 is slidably connected on the rear plate 208 for quick assembly and disassembly of the infrared detection device 102.

[0033] In use, the two sets of movable plates 203 of the quick-release component 200 can be connected to or disconnected from the side slots 212. When the infrared detection device 102 needs to be removed for maintenance, the movable plates 203 are disconnected from the side slots 212, and the push plate 211 moves to push the infrared detection device 102 outward, realizing the quick assembly and disassembly of the U-shaped frame 201 and the infrared detection device 102, replacing the traditional method of using screws for assembly and disassembly, which facilitates the maintenance of the infrared detection device.

[0034] Example 2

[0035] Reference Figures 1 to 5 This is the second embodiment of the present invention. Unlike the previous embodiment, the drone body 100 is provided with a connecting line 103, and a plug 104 is installed on the connecting line 103. The plug 104 is connected to a slot opened on the drone body 100. The infrared detection device 102 can be connected to the drone body 100 through the plug 104 and the connecting line 103. When the remote control operates the drone body 100, it can also control the infrared detection device 102 to work and display the thermal imaging image detected by the infrared detection device 102.

[0036] The quick-release component 200 also includes a movable rod 202 that is inserted through both ends of the U-shaped frame 201, and the movable rod 202 is fixedly connected to the movable card plate 203.

[0037] Furthermore, a spring 204 is fitted on the outer wall of the moving rod 202. The spring 204 is located between the moving plate 203 and the inner wall of the U-shaped frame 201. The elasticity of the spring 204 allows the moving plate 203 to always move toward the infrared detection device 102. After the moving rod 202 is pulled outward, the moving plate 203 disengages from the side slot 212. After the infrared detection device 102 is unrestricted, it can disengage from the U-shaped frame 201.

[0038] The inner wall of the U-shaped frame 201 is provided with two sets of guide grooves 213, and each set of guide grooves 213 is slidably connected with a slider 214, and the slider 214 is fixedly connected to the moving plate 203; the sliding connection between the guide grooves 213 and the sliders 214 plays a guiding role in the lateral movement of the moving plate 203.

[0039] Among them, a telescopic rod 209 is fixedly connected between the rear plate 208 and the push plate 211, and the outer wall of the telescopic rod 209 is fitted with a spring 210; through the elasticity of the telescopic rod 209 and the spring 210, the push plate 211 can always move towards the front end of the U-shaped frame 201, and the unrestricted infrared detection device 102 on the U-shaped frame 201 can be quickly pushed out.

[0040] The end of the moving rod 202 away from the moving plate 203 is fixed with a pull ring, and a stop hole 205 is provided on the moving rod 202.

[0041] Furthermore, both outer walls of the U-shaped frame 201 are provided with damping shafts 206, and stop rods 207 are installed on the damping shafts 206 for limiting the movement of the stop hole 205 and the moving rod 202. After the moving plate 203 is connected to the side slot 212, the stop rod 207 rotates to position it within the stop hole 205, thus limiting the position of the moving rod 202 and preventing the moving plate 203 from disengaging from the side slot 212 during the flight of the UAV body 100. This improves the stability of the infrared detection device 102 mounted on the U-shaped frame 201. The damping shaft 206 has a certain resistance, and the stop rod 207 requires external force to rotate, ensuring the stability of the stop rod 207 connected within the stop hole 205. After the stop rod 207 disengages from the stop hole 205, the moving rod 202 can be pulled outward without restriction, causing the moving plate 203 to disengage from the side slot 212, thus realizing the disassembly of the infrared detection device 102.

[0042] When in use, the remote controller controls the drone body 100 to fly, and the camera 101 transmits the flight image to the display screen of the remote controller. When the infrared detection device 102 is aimed at the high insulator of the outdoor power system, the infrared detection device 102 transmits the temperature of the insulator to the display screen of the remote controller. The temperature of a normal insulator is evenly distributed, while the inferior insulator will overheat locally due to the increase of leakage current, which can be clearly distinguished in the thermal imaging image.

[0043] When the infrared detection device 102 needs maintenance, both sets of moving rods 202 of the quick-release component 200 are pulled outward, causing the moving plate 203 to disengage from the side slot 212. The telescopic rod 209, in conjunction with the elasticity of the second spring 210, pushes the push plate 211 forward, pushing out the unrestricted infrared detection device 102. This achieves quick assembly and disassembly of the U-shaped frame 201 and the infrared detection device 102, facilitating the maintenance of the infrared detection device 102. During installation, the moving plate 203 is installed in the side slot 212, and the stop rod 207 rotates to position it in the stop hole 205, thus limiting the position of the moving rod 202 and preventing the moving plate 203 from disengaging from the side slot 212 during the flight of the UAV body 100. This improves the stability of the infrared detection device 102 installed on the U-shaped frame 201.

[0044] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
