Description

Technical Field

[0001] The invention relates to the technical field of power supply and communication devices, and in particular to an underwater accompanying power supply and communication device for a plane gate. Background Art

[0002] The gate is an important water retaining and flood discharge equipment in water conservancy and hydropower projects. The safe operation of the gate directly affects the safety of a power station and even the safety of the entire reservoir downstream. Since the gate operates underwater, without knowing the real-time status of the underwater gate, the operator can only estimate the expected position and status of the gate through the values ​​displayed by the load, stroke and other detection devices installed on the gate hoist. Many major accidents have occurred in China due to misjudgment.

[0003] Long-term online monitoring of gates underwater is imperative, but underwater sensors require not only power supply but also a good communication circuit. At present, reliable power supply and communication circuit are the primary issues restricting underwater monitoring of gates. Gates have two operating conditions: underwater and above water. In most cases, the two operating conditions are constantly switched with the gate's operating requirements. There are four reasons why the accompanying cable solution commonly used in the elevator industry is not suitable for gates: 1. When the gate is running in the gate slot, the maximum gap between the gate slot and the gate is only 300mm, which cannot meet the space requirements for the U-shaped return of the accompanying cable. 2. When the gate is blocking or discharging water underwater, the accompanying cable will be washed by the water flow or hit by floating objects in the water, causing the accompanying cable to be knotted or damaged. 3. When the gate is running on the water surface, the scorching sun or strong wind on the water surface will also damage the accompanying cable. 4. The accompanying cable generally has a high tensile strength. If a part of it falls into the gate running gap after being broken, knotted or damaged, it will cause the gate to be blocked, and the consequences will be disastrous. Summary of the invention
