Description

TECHNICAL FIELD

[0001] The application relates to the technical field of electric power inspection, and in particular to an image acquisition device for electric power inspection. BACKGROUND

[0002] Electric power inspection refers to the periodic inspection and maintenance work on various devices in an electric power system, and the process is crucial because it is directly related to the normal operation and safety and stability of the electric power system. When performing the electric power inspection task, the inspection personnel must observe and record various electric power devices in detail, so as to discover potential problems existing in the devices in a timely manner and take measures to process the problems quickly, so as to prevent the problems from being enlarged to affect power supply. However, the traditional electric power inspection mode mainly depends on manual work. Although this mode can complete the inspection task to a certain extent, the efficiency is relatively low, and the mode is easily affected by human factors, such as fatigue, negligence or lack of experience of the inspection personnel, which may lead to inaccurate inspection results. In view of this, with the continuous progress and innovation of science and technology, more and more electric power inspection work begins to use automatic and intelligent image acquisition devices. These advanced technical means can not only significantly improve the efficiency of the inspection, but also enhance the accuracy of the inspection, thereby providing a more powerful guarantee for the stable operation of the electric power system.

[0003] According to the patent document CN206260019U, an image acquisition device for electric power inspection is disclosed, which is internally provided with an infrared camera unit and a control circuit board. The infrared camera unit includes a base fixed in the image acquisition device, a first infrared lens fixed on the base, and an image acquisition device body. A second infrared lens is located between the first infrared lens and the image acquisition device body and is movably arranged on the same axis as the first infrared lens. A driving mechanism and a rotating mechanism are also arranged on the base. The driving mechanism drives the second infrared lens connected to the rotating mechanism to rotate away from the axis to change the far field or near field of the image acquisition device. The control circuit board is electrically connected to the driving mechanism. The helicopter-borne image acquisition device changes the infrared lens to realize the far field or near field of the image acquisition device, which facilitates better shooting of the fault points of the fault line.

[0004] In the process of power distribution network inspection, people often use the advanced technology of robot dog to perform tasks, and the robot dog is equipped with a thermal imager when inspecting the power distribution network, which can observe and measure the thermal abnormality of electrical components. Such operation helps to discover potential fault points in time to arrange maintenance work and eliminate safety hazards. Since there is a certain distance between the robot dog and the detected power grid, the lens of the infrared imager needs to be adjusted for far and near field of view to ensure the accuracy of the detection results. The traditional robot dog usually switches the far and near field of view by the extension and contraction of the lens, but this design has some problems in actual operation. When the robot dog works in the air, the stability of the lens cannot be guaranteed during the extension and contraction process. Due to the influence of wind and other external factors, the lens may vibrate, which will cause the photographed image to be blurred, thereby seriously affecting the effect and quality of the inspection work. SUMMARY

The outer walls of the plurality of telescopic blocks 3218 are slidably connected to the inner walls of the plurality of guide grooves 3216 of the chute plate 3213. The rear sides of the plurality of telescopic blocks 3218 are rotatably connected with a plurality of bidirectional hinge rods 3219. The lens connecting assembly 322 comprises a transmission shaft 3221. The inner wall of the transmission shaft 3221 is threadedly connected to the outer wall of the lead screw 3214. The outer wall of the transmission shaft 3221 is fixedly connected with a plurality of L-shaped connecting rods 3222 in an annular array. The inner walls of the plurality of L-shaped connecting rods 3222 are fixedly connected with a plurality of sleeves 3223. The inner walls of the plurality of sleeves 3223 are slidably connected to the outer wall of the chute plate 3213. The front side of the sleeve 3223 is fixedly connected with a push-pull plate 3224. The front side of the push-pull plate 3224 is provided with a lens connecting groove 3225. The inner wall of the lens connecting groove 3225 is fixedly connected to the outer wall of the front side of the lens 318. The outer wall of the bottom of the push-pull plate 3224 is fixedly connected to the inner sides of the two L-shaped connecting blocks 316. The front side of the transmission shaft 3221 is rotatably connected to the rear sides of the plurality of bidirectional hinge rods 3219.

[0034] When detecting the power facility, in order to ensure the accuracy of the detection result, we often need to adjust the far and near field of view of the lens. At this time, we can start the power element 3211 to achieve this purpose. After the power element 3211 is activated, the output end thereof drives the lead screw 3214 to rotate. With the rotation of the lead screw 3214, the screw transmission principle starts to work, thereby driving the transmission shaft 3221 to move forward. During the forward movement of the transmission shaft 3221, the L-shaped connecting rod 3222 and the sleeve 3223 are sequentially driven to move forward. During the forward movement of the sleeve 3223, the push-pull plate 3224 is pushed to move forward. During the forward movement of the push-pull plate 3224, the lens 318 in the lens connecting groove 3225 is pulled to move forward. This series of mechanical actions finally realizes the adjustment of the position of the lens 318, so that the device can adjust the far and near field of view of the lens 318 according to the actual distance between the detected object and the device, thereby significantly improving the accuracy of the detection result.

[0035] Meanwhile, during the forward movement of the transmission shaft 3221, the plurality of bidirectional hinge rods 3219 are also caused to rotate. During the rotation of the bidirectional hinge rods 3219, the telescopic blocks 3218 are guided to slide on the inner walls of the guide grooves 3216. During the sliding of the telescopic blocks 3218, the telescopic column rods 3217 are pushed to slide on the inner walls of the through holes 3215. When the telescopic column rods 3217 slide and expand outward, they are clamped on the inner walls of the sleeve 3223, thereby achieving the limiting and fixing of the sleeve 3223. This mechanism further improves the accuracy and stability of the adjustment of the lens 318.

[0036] In addition, the visible light camera 317 is a device that captures images in the visible light spectrum, which can clearly capture images of power facilities and their surroundings. During power inspection, the visible light camera 317 plays a crucial role in capturing real-time images of key equipment such as power lines, transformers, and switches, providing intuitive and accurate on-site information for inspectors. Through analysis of the captured images, inspectors can promptly identify defects and potential hazards in equipment, thereby taking appropriate maintenance measures to ensure the safe and stable operation of the power system. In addition, the visible light camera 317 has high resolution and dynamic range, which can maintain image clarity and color restoration under different lighting conditions, further improving the efficiency and accuracy of power inspection.

[0037] When the push-pull plate 3224 moves forward to pull the lens 318 to extend, this action will trigger a series of precise mechanical linkages. At this time, the movement of the push-pull plate 3224 is not limited to itself, but it will further drive two L-shaped connecting blocks 316 connected to the push-pull plate 3224. Their movement will directly affect the position of the stop block 315, which will smoothly slide along the inner wall of the sliding groove rod 313 during movement. This process ensures smooth and accurate movement. At the same time, the oblique cut surface at the top of the stop block 315 is designed cleverly, which will contact the cut surface at the bottom of the second stop block 3199. This contact is not a simple collision, but a carefully designed contact method that can generate effective extrusion force. This extrusion force enables the second stop block 3199 to effectively drive the cylindrical crossbar push-pull rod 3198 to move accordingly. During the movement of the push-pull rod 3198, it will drive another cylindrical crossbar 3197 to slide along the inner wall of the push-pull block sliding groove 3196. This series of sliding actions ensures smooth operation of the entire mechanical structure. Finally, the push-pull block 3195 moves under the push of this series of actions, and the movement of the push-pull block 3195 drives the clamping plate 3194 to rotate. During the rotation of the clamping plate 3194, it gradually approaches the middle section of the lens 318 until the inner wall of the clamping plate 3194 tightly fits the outer wall of the middle section of the lens 318, thereby achieving the effect of firmly clamping the extended lens 318. This clamping not only ensures the stability of the lens 318 during use, avoiding lens shaking, but also further improves the stability and service life of the lens 318. In addition, when the push-pull plate 3224 moves backward to shorten the lens 318, the entire process will be reversed, and the stop block 315 will also move backward. At this time, the extrusion force between the second stop block 3199 and the stop block 315 will gradually decrease until the clamping plate 3194 releases the lens 318, allowing the lens 318 to be shortened smoothly. This design ensures that the extension and retraction of the lens 318 is convenient and reliable, providing great convenience for users.
