Description

Technical Field

[0001] This utility model belongs to the field of cables, specifically relating to underwater cables with water level monitoring sensors. Background Technology

[0002] Underwater cables with water level monitoring sensors are composite cables specifically designed for underwater environments, combining power transmission, signal transmission, and water level monitoring functions. Their core design goal is to monitor water level changes in real time while transmitting electrical energy or data. They are widely used in fields such as hydrological monitoring, dam safety, seabed observation networks, and marine energy development.

[0003] Water level monitoring is a crucial aspect of ensuring the safety of underwater cable operation. It typically relies on monitoring devices installed on the cable's outer wall. Traditional underwater cables with water level sensors usually have these devices directly fixed to the cable's outer wall. However, when these devices malfunction or require regular maintenance, disassembly and maintenance become extremely inconvenient due to their underwater location. Traditional fixing methods may employ numerous screws or other complex structures, leading to time-consuming and labor-intensive disassembly in an underwater environment. This may even require specialized divers to perform prolonged underwater operations, increasing maintenance costs and posing safety risks. Furthermore, monitoring devices directly fixed to the cable's outer wall are prone to damaging the cable itself during disassembly, affecting its normal operation and potentially leading to more serious safety issues. Utility Model Content

A screw hole three is opened on the inner wall edge of the slot away from the sealing box. A screw is installed in the screw hole four with internal threads. The screw passes through the screw hole four and is threaded in the screw hole three.

[0006] Furthermore, the monitoring device also includes a support rod and a spring. The support rod is fixed to the center of the inner wall at both ends of the sealed box, and a movable cylinder is fitted onto the outer wall of the support rod.

[0007] Furthermore, a monitoring device is fixedly connected to the two ends of the movable cylinders that are close to each other, and a spring is wrapped around the outer wall of the support rod, with one end of the spring fixedly connected to the edge of the two ends of the support rod that are close to each other.

[0008] Furthermore, the other end of the spring is fixed to the edge of the movable cylinder that is far apart from each other, and a guide plate is fixed to the upper edge of the sealing box, with the guide plate pointing towards the pressure sensor.

[0009] Furthermore, the fixing device also includes a second fixing sleeve and a soft pad. The second fixing sleeve is hinged to one end of the first fixing sleeve, and the other ends of the first fixing sleeve and the second fixing sleeve are respectively fixed to a first fixing block and a second fixing block.
