Abstract
Description
Technical Field
[0001] This application relates to the field of transmission line diagnostic devices, and more particularly to a distributed fault diagnosis device for transmission lines. Background Technology
[0002] In daily use, power distribution lines need to be inspected regularly by staff to ensure their normal operation, identify and resolve potential safety hazards in advance, and prevent power distribution line failures from causing significant economic losses.
[0003] However, while manual patrols can detect potential equipment hazards, their limitations mean that monitoring power distribution lines is periodic rather than continuous, resulting in poor timeliness in detecting potential hazards. Therefore, a more efficient and scientific online monitoring system for power transmission lines is needed.
[0004] Existing power distribution line detection systems typically consist of fault diagnosis devices installed at intervals along the power distribution line. These devices include temperature detection mechanisms to detect the temperature of the power distribution line, tilt detection mechanisms to detect the tilt of the power distribution line, and cameras to monitor the overall condition of the current section of the power distribution line and the external weather conditions.
[0005] Common fault diagnosis devices typically include a cylindrical mounting housing with a wire hole coaxially extending through both ends. A power cable passes through the wire hole, and the sidewall of the wire hole abuts against the power cable, thus fixing the mounting housing to the power cable. The camera, temperature detection mechanism, and tilt detection mechanism are all housed inside the mounting housing.
[0006] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Since the camera, temperature detection mechanism, tilt detection mechanism, and power distribution cable are all located in the same space, and the power distribution cable seals the wire hole, the inside of the mounting housing is a sealed space. This makes it difficult for the heat generated by the camera during operation to dissipate from the mounting housing, resulting in excessively high temperatures inside the mounting housing that affect the operation of the camera. It can also easily mislead the temperature detection mechanism. In addition, the heat generated when the power distribution cable transmits power can also interfere with the camera. Utility Model Content
[0007] To address the problem that poor heat dissipation of cameras interferes with their operation in traditional power distribution line fault diagnosis devices, which are installed in the same space as the camera, power distribution line, temperature detection mechanism, and tilt detection mechanism, this application provides a distributed fault diagnosis device for power transmission lines.
[0008] The distributed fault diagnosis device for power transmission lines provided in this application adopts the following technical solution:
[0009] A distributed fault diagnosis device for power transmission lines includes a first mounting shell, a temperature detection mechanism, a tilt detection mechanism, a second mounting shell mounted on the first mounting shell, and a camera installed inside the second mounting shell. The first mounting shell is mounted on the power distribution line, and the temperature detection mechanism and the tilt detection mechanism are both located inside the first mounting shell. The second mounting shell has a monitoring hole for monitoring the outside world in conjunction with the camera.
[0010] By using the above technical solution, the camera is isolated and installed in the second mounting housing, making the operating temperature of the camera less susceptible to the influence of the temperature of the power distribution wires, temperature detection mechanism, and tilt detection mechanism in the first mounting housing, thus making the camera's operation more stable.
[0011] Optionally, a heat-conducting hole is provided on the side wall of the second mounting shell, and the heat-conducting hole is opposite to the monitoring hole.
[0012] Optionally, the second mounting housing is provided with a bracket, which includes a support rod and a mounting plate. The mounting plate is mounted on the end face of the second mounting housing with the monitoring hole through the support rod, and the camera is mounted on the mounting plate.
[0013] Optionally, the second mounting shell and the first mounting shell are integrally connected and communicate with each other. A partition plate is detachably installed on the bottom of the second mounting shell. The partition plate is used to separate the first mounting shell and the second mounting shell. A wiring hole is provided through the partition plate.
[0014] With the above technical solution, after the first mounting shell and the second mounting shell are connected as a whole, only one power supply needs to be installed in the first mounting shell to supply power to all mechanisms. Compared with the separate installation, which requires two power supplies, the structure is simpler and the cost is lower.
[0015] Optionally, the wiring hole is located on one side of the heat-conducting hole.
[0016] Optionally, a third mounting shell is provided inside the first mounting shell, and the third mounting shell and the camera are respectively located at both ends of the first mounting shell. The temperature detection mechanism and the tilt detection mechanism are both located inside the third mounting shell.
[0017] Optionally, a retaining edge is provided on the side wall of the second mounting housing, and the partition plate is fitted and pressed against the retaining edge.
[0018] Optionally, an installation groove is provided around the edge, and a sealing ring is embedded in the installation groove. A pressing groove corresponding to the installation groove is provided on the partition plate. When the partition plate is pressed against the edge, the inner wall of the pressing groove presses against the sealing ring.
[0019] Optionally, both the first mounting shell and the second mounting shell are provided with heat insulation cavities.
[0020] Optionally, the third mounting housing is provided with an arc-shaped groove that mates with the power distribution wire passing through the first mounting housing. The temperature detection mechanism is arranged along the arc-shaped groove surface of the third mounting housing. The first housing includes an upper housing and a lower housing. The mating surfaces of the upper housing and the lower housing are defined as the first surface and the second surface, respectively. The first surface is provided with a positioning protrusion, and the second surface is provided with a positioning groove. When the upper housing and the lower housing are mated, the positioning protrusion is fitted into the positioning groove.
[0021] In summary, this application features a second mounting housing mounted on a first mounting housing, with the camera installed in the second mounting housing. A partition plate separates the first and second mounting housings, preventing thermal interaction between them. This makes the camera less susceptible to heat generated by the power cables, temperature detection mechanism, and tilt detection mechanism within the first mounting housing during operation. Simultaneously, heat is dissipated through heat-conducting holes, maintaining a stable ambient temperature within the second mounting housing. Furthermore, limited thermal interaction between the first and second mounting housings is achieved through wiring holes, maintaining a stable internal temperature within the first mounting housing. This prevents the temperature within the first mounting housing from becoming excessively high, which could lead to misjudgments by the temperature detection mechanism. Additionally, since the wiring holes are located at the heat-conducting holes, heat dissipated at the wiring holes is promptly dissipated, minimizing its impact on the overall temperature within the second mounting housing.
