[0018] Specifically, the upper connecting frame 1 and the lower bin body 7 are connected through the structure of the clamping assembly. Not only simplifies the installation process, but also is fast and does not need additional tools, and ensures the stability and reliability of the device, which is very suitable for rapid deployment in the field operation environment.

[0019] The clamping assembly comprises a locking sleeve 2, an upper connecting clamp 3, a connecting column 4 and a lower connecting clamp 5, the two sides of the upper connecting frame 1 are provided with the upper connecting clamp 3, the upper connecting clamp 3 is correspondingly provided with the lower connecting clamp 5 arranged on the two sides of the lower bin body 7, the upper connecting clamp 3 and the lower connecting clamp 5 are connected through the connecting column 4, and the upper end of the connecting column 4 is provided with the locking sleeve 2.

[0020] Specifically, the locking sleeve 2 is located at the upper end of the connecting column 4, which ensures the stable connection between the upper connecting frame 1 and the lower bin body 7.

[0021] Further, the locking sleeve 2 has internal threads or similar fixing mechanism, which can be screwed on the connecting column 4, so as to press the upper connecting clamp 3 and the lower connecting clamp 5, preventing them from loosening.

[0022] The upper connecting clamp 3 is provided with a strip-shaped slot 9 in the middle, so as to cooperate with the lower connecting clamp 5 on the lower bin body 7, the upper connecting clamp 3 provides positioning in the vertical direction, and ensures the stability in the horizontal direction through its structural characteristics.

[0023] Specifically, the connecting column 4 plays the role of a bridge, which transmits the pressure from the upper part to the lower part, and maintains the correct distance between the upper and lower parts; in order to adapt to different installation conditions, the connecting column 4 has a certain degree of adjustability.

[0024] The lower connecting clamp 5 is similar to the upper connecting clamp 3, and the two are correspondingly arranged, which facilitates the rapid butt joint in the installation process.

[0025] The upper end of the upper connecting frame 1 is also provided with a strip-shaped slot 9, and an inner clamping column 10 is arranged in the strip-shaped slot 9. The inner clamping column 10 is connected with a bracket side clamping plate 11 arranged at the upper end of the lower bin body 7. A clamping sleeve seat 17 is arranged on the inner clamping column 10 below the bracket side clamping plate 11. A connecting rotating sleeve 8 is arranged on the inner clamping column 10 at the upper end of the strip-shaped slot 9.

[0026] The upper end of the upper connecting frame 1 is provided with a strip-shaped slot 9, and an inner clamping column 10 is arranged in the strip-shaped slot 9. The inner clamping column 10, the bracket side clamping plate 11 arranged on the lower bin body 7, the clamping sleeve seat 17 and the connecting rotating sleeve 8 jointly form an auxiliary locking and adjusting mechanism, further enhancing the stability and installation flexibility of the device.

[0027] Specifically, the strip-shaped slot 9 provides a space for the movement of the inner clamping column 10, thereby adapting to different installation conditions. The strip-shaped slot 9 can meet the fine adjustment needs that may be encountered during installation, allowing the inner clamping column 10 to freely slide within a certain range to ensure optimal alignment.

[0028] Specifically, the inner clamping column 10 is arranged in the strip-shaped slot 9 and connected with the bracket side clamping plate 11 on the lower bin body 7. The inner clamping column 10 provides an additional fixing point, further ensuring the practicality of the device.

[0031] The lower bin body 7 is provided with a detection main body 16, and a fan group 13 for heat dissipation is arranged below the detection main body 16.

[0032] Specifically, the detection main body 16 is responsible for monitoring the traveling wave signals on the power transmission line and determining the specific location of the line fault by analyzing these signals.

[0033] Specifically, the fan group 13 provides necessary cooling for the detection main body 16 to prevent performance degradation or equipment damage due to overheating. The fan group 13 can accelerate air circulation and remove heat generated by the detection main body 16, maintaining an appropriate working temperature range.

[0034] Further, one side of the lower bin body 7 is provided with an access door, and one side of the access door is provided with a handle 6.

[0035] The access door provides technicians with direct access to internal components such as the detection body 16, fan group 13, etc., making routine inspections, troubleshooting, and component replacement much easier.

[0036] Furthermore, the access door has a good sealing mechanism to prevent dust, moisture, or other contaminants from entering the inside of the lower bin body 7, protecting sensitive electronic components.

[0037] With a reasonable locking mechanism, it is ensured that the access door will not accidentally open during operation, avoiding potential safety hazards.

[0038] Specifically, the handle 6 allows technicians to easily grasp and apply appropriate force to open or close the access door. This not only improves work efficiency, but also reduces the risk of injury caused by improper force.

[0039] Further, the lower bin body 7 is provided with a partition 15, and the partition 15 is provided with an intermediate stop block, and the detection body 16 is located on both sides of the intermediate stop block.

[0040] Further, the inner wall of the lower bin body 7 and the inner side of the access door are provided with a flexible elastic seat 12.

[0041] The flexible elastic seat 12 can effectively absorb the vibration energy from the outside world, reducing the impact of these vibrations on sensitive components such as the internal detection body 16, and maintaining the accuracy of measurement data.

[0042] In the event of an accidental impact on the device, the flexible elastic seat 12 can act as a buffer to reduce the impact of the impact force on the internal structure and electronic components.

[0043] Further, the lower bottom plate of the lower bin body 7 is provided with a pad plate 14, and the pad plate 14 is provided with a fan group 13.

[0044] Further, the partition 15 is provided with a ventilation opening, and the ventilation opening is inclined.

[0045] Specifically, the ventilation holes on the partition 15 are arranged at an inclined angle, which takes advantage of gravity to allow incoming cool air to flow more smoothly to the areas that need to be cooled, while also being more efficient when expelling hot air. This optimizes the air circulation path, effectively prevents dust and moisture from entering, enhances the cooling effect, and ensures that internal electronic components can operate at an appropriate working temperature.

[0046] In use: the upper connecting card 3 on both sides of the upper connecting frame 1 is aligned with the lower connecting card 5 on both sides of the lower bin body 7, and is inserted into the connecting column 4, and the locking sleeve 2 is screwed on the top of the connecting column 4, to ensure that the upper and lower parts are tightly combined and cannot be loose. This process should ensure that the connection is stable, while checking whether each part is correctly engaged, inserting the inner card column 10 into the strip-shaped slot 9 of the upper connecting frame 1, and docking it with the bracket side card plate 11 on the lower bin body 7, locking the inner card column 10 with the card sleeve seat 17 to prevent accidental movement in the strip-shaped slot 9, starting the detection main body 16 to start monitoring the traveling wave signals on the power transmission line, and determining the specific location of the line fault by analyzing these signals, when cooling is needed, the fan group 13 is turned on to ensure that the cooling system is working properly, and to provide a good heat dissipation environment for the detection main body 16.
