Description

Technical Field

[0001] The utility model relates to the technical field of cable leakage detection, in particular to a new energy equipment leakage detection cable device. Background Art

[0002] New energy is also called unconventional energy. It refers to various forms of energy other than traditional energy. It refers to energy that has just begun to be developed or is being actively studied and is yet to be promoted, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy, and nuclear fusion energy. New energy equipment requires cables, and since the cable surface may be worn or gnawed by mice, leakage may occur, and leakage points need to be detected.

[0003] A Chinese patent with authorization announcement number CN212905363U discloses an efficient cable leakage detection device, including a telescopic rod. During detection, the operator adjusts the length of the telescopic rod and lifts the telescopic rod. Since the connector drives the box through the lifting ring, an acoustic wave detector is placed in the box. When the acoustic wave detector detects a leakage, the data interface converts the signal into data and transmits it to the terminal device through the data line for data analysis. When it is necessary to detect the upward direction, the operator straightens the box with his hand and pushes the protrusion in his hand upward. Since the protrusion is connected to the support rod, the support rod is driven to move upward. With the help of the thrust, the detection port of the box faces upward. When the detection direction needs to be adjusted, due to the action of the lifting ring, the box can be flipped to meet the detection requirements. The pulley on the box can slide along the wall for detection, which effectively reduces the friction, thereby solving the problem that the cable detection device is inconvenient to carry and use.

[0004] However, the device still has some shortcomings: when the cable height fluctuates, the length of the support rod needs to be adjusted in real time, and the device limits the support rod by positioning pins, which is time-consuming and labor-intensive in actual operation, affecting the efficiency of cable detection.
