[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0030] Embodiment one

[0031] Please refer to Figs. 1-2 The embodiment of the present application provides a 10kV periscopic cable room inspection device, which comprises a periscope assembly 1, a flashlight 2 and an infrared thermometer 3.

[0032] The periscope assembly 1 is ingeniously arranged on the cabinet door of the cable room. The periscope assembly 1 has two key ports, namely a viewing end 101 inside the cable room and an observation end 102 outside the cable room. In actual application, the periscope assembly 1 can be cooperated with the flashlight 2 and the infrared thermometer 3 to achieve the functions of visual observation and infrared measurement of the inside of the cable room. Specifically, the flashlight 2 can provide sufficient illumination to assist the periscope assembly 1 to obtain clear images, and the infrared thermometer 3 can measure the temperature of the equipment inside the cable room through the channel of the periscope assembly 1.

[0033] The core point of the innovative scheme proposed in the embodiment of the present application is to carefully arrange the periscope assembly 1 on the cabinet door of the cable room and make it form an effective cooperation mechanism with the flashlight 2 and the infrared thermometer 3, so as to successfully realize the visual observation and infrared measurement of the inside of the cable room. The research and application of this device can effectively deal with and solve a series of outstanding problems faced by the existing full-insulation cabinet cable room in daily operation and maintenance work.

[0034] From the perspective of visual observation, on the one hand, the viewing end of the periscope assembly 1 can reach the key area inside the cable room. Under the bright lighting condition provided by the flashlight 2, the operator can directly observe the crucial part of the cable terminal head. Even if the cable room is in a fully sealed state, the device can still clearly obtain the image information of the internal equipment. This feature successfully overcomes the difficulty of traditional observation window due to limited field of view or the blocking of transparent adhesive plate, greatly improving the convenience and accuracy of the inspection work.

[0035] On the other hand, in terms of infrared measurement, the infrared thermometer 3 can make full use of the channel built by the periscope assembly 1 to conduct non-contact temperature measurement on the equipment inside the cable chamber. Through this advanced measurement method, temperature rise of the equipment caused by various faults can be found in time. This function effectively makes up for the shortcomings of the prior art in cable terminal head fault detection, because in the previous technical conditions, the cable terminal head faults are often difficult to be found in time, which may lead to more serious consequences.

[0036] In addition, the 10kV periscopic cable chamber inspection device also has many advantages such as simple structure and convenient operation. The simple and reasonable structure design makes the installation and maintenance of the device more relaxed, and the convenient operation mode reduces the work difficulty and operation failure rate of the operation and maintenance personnel. Based on these advantages, the device can be widely used in the daily operation and maintenance work of the distribution network cable chamber. In practical application, it can significantly improve the efficiency of operation and maintenance, reduce operation time and labor cost; at the same time, through real-time monitoring and accurate measurement of the running state of the equipment, the safety of the equipment operation is effectively improved, and the probability of equipment failure is reduced, which provides strong guarantee for the stable operation of the distribution network.

[0037] In a specific embodiment presented in this embodiment, the periscope assembly 1 is cleverly arranged on the cabinet door of the cable chamber in a movable manner. Specifically, it has the flexibility to move up and down in the vertical direction, and can also rotate around the horizontal direction. This flexible and movable arrangement allows the periscope assembly 1 to observe the inside of the cable chamber at different positions and angles, greatly expanding the observation range and flexibility, and providing strong support for comprehensive and detailed inspection of the inside of the cable chamber.

[0038] The flashlight 2 is precisely arranged at the side of the viewfinder end 101 of the periscope assembly 1. Its core function is to emit light and accurately illuminate the areas that need to be observed inside the cable chamber, providing necessary lighting conditions for clear observation of the internal equipment. It is worth mentioning that the flashlight 2 has an advanced automatic light adjustment function. This function relies on its internal precise design and can automatically and intelligently adjust its brightness according to the actual light intensity inside the cable chamber. Whether the light inside the cable chamber is relatively dim or relatively bright, the flashlight 2 can quickly respond and adjust to the most appropriate brightness to ensure clear and stable lighting for observation under various lighting conditions, thereby ensuring the accuracy and reliability of the observation effect.

[0039] The infrared thermometer 3 is reasonably arranged at the observation end 102 of the periscope assembly 1. It uses the optical reflection principle inside the periscope assembly 1 to accurately measure the surface temperature of the equipment in the cable chamber in an advanced non-contact measurement way. This non-contact measurement method not only avoids interference or damage to the equipment caused by contact with the equipment, but also improves the safety and convenience of measurement. The measurement range of the infrared thermometer 3 is carefully designed and calibrated, which can fully cover the temperature range of the equipment in the cable chamber under normal working conditions, ensuring the comprehensiveness and accuracy of the equipment temperature monitoring. In addition, the infrared thermometer 3 also has the important function of high temperature alarm. When it detects that the surface temperature of the equipment exceeds the pre-set safety threshold during monitoring, it will immediately trigger the high temperature alarm mechanism and send a warning signal to the relevant personnel in time, so that the operation and maintenance personnel can quickly take measures to troubleshoot and prevent more serious damage or safety accidents caused by high temperature of the equipment.

[0040] The periscope assembly 1 is movably arranged by an advanced electric drive device. This electric drive device has high intelligence and automation characteristics, which can automatically and accurately adjust the up-down position of the periscope assembly 1 in the vertical direction and the rotation angle in the horizontal direction according to the pre-set program or the received remote control instructions. In this way, the periscope assembly 1 can perform comprehensive and systematic inspection of the inside of the cable chamber according to the pre-set inspection route or actual needs, ensuring that every corner can be carefully observed without missing any potential problems or hidden dangers.

[0041] The automatic light adjustment function of the flashlight 2 is realized by the cooperation of the built-in high-precision photosensitive sensor and the intelligent control unit. The photosensitive sensor is like the "eyes" of the flashlight 2, which can monitor the light intensity changes in the cable chamber in real time and accurately, and quickly and accurately transmit these monitored data to the control unit. The control unit is like the "brain" of the flashlight 2, which analyzes and processes the received light intensity data according to the pre-set light adjustment algorithm, and then automatically and accurately adjusts the brightness of the flashlight 2. This intelligent light adjustment mechanism ensures that the flashlight 2 can provide just the right amount of light under different lighting conditions, providing a stable and clear light environment for observing the equipment in the cable chamber.

[0042] The infrared temperature measuring instrument 3 adopts a modular design concept in structural design, and mainly comprises three core parts of a temperature measuring unit, a data processing unit and a wireless communication module. The temperature measuring unit is responsible for directly measuring the surface temperature of the equipment in the cable chamber and obtaining original temperature data. The data processing unit is like an "analysis center" of the infrared temperature measuring instrument 3, which can perform real-time and in-depth analysis on the temperature data measured by the temperature measuring unit. When the analysis result shows that the surface temperature of the equipment is abnormally high, the data processing unit will immediately transmit the high-temperature alarm information to the mobile terminal of the operation and maintenance personnel or the monitoring center through the wireless communication module. In this way, the operation and maintenance personnel can obtain the information of the abnormal temperature of the equipment in the first time, take corresponding measures in time, effectively avoid the further expansion of equipment failure, and ensure the safe and stable operation of the cable chamber.

[0043] In order to facilitate the installation, disassembly and maintenance and replacement of the flashlight 2 and the infrared temperature measuring instrument 3, the flashlight 2 and the infrared temperature measuring instrument 3 are ingeniously arranged on the periscope assembly 1 through a quick release structure. The quick release structure is reasonable in design and easy to operate. The operation and maintenance personnel can quickly and easily disassemble the flashlight 2 or the infrared temperature measuring instrument 3 from the periscope assembly 1 for inspection, repair or replacement without the help of complex tools, greatly improving the efficiency and convenience of operation and maintenance, reducing the downtime caused by equipment maintenance, and further improving the practicability and reliability of the entire cable chamber inspection device.

[0044] Although the flashlight, the infrared temperature measuring instrument and other terms are used more in the present application, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present application; any additional limitation is contrary to the spirit of the present application.

[0045] Finally, it should be pointed out that although the above-mentioned embodiments have been described in the specification and drawings of the present application, the patent protection scope of the present application should not be limited. Any equivalent structure or equivalent process substitution or modification based on the essential concept of the present application, and the direct or indirect implementation of the technical solutions of the above embodiments in other related technical fields, are all included in the patent protection scope of the present application.
