Remote automatic locking and unlocking device of reservoir strobe

Abstract

The invention discloses a remote automatic locking and unlocking device of a reservoir strobe, comprising a strobe vertical shaft, a strobe body, a locking block and a strobe control system, wherein the strobe control system is used for controlling the strobe; the locking block is also provided with an electric hydraulic mechanism; the locking block and the electric hydraulic mechanism are arranged at both edges of the strobe body; and the strobe control system can control the electric hydraulic mechanism to be put to and retreated from the locking block. The strobe control system controlling the strobe can not only remotely control the lifting of the strobe, but also modify the strobe control system when the remote automatic locking and unlocking device is installed and also remotely control the locking block, thereby removing the limit that a worker is necessary to move for locking in-place without needing the worker to reach a field for the operation of the strobe; and in addition, the remote automatic locking and unlocking device has the advantages of small equipment volume, simple distribution, simple transmission mode, low investment cost and convenient maintenance and is suitable for the condition of insufficient field equipment distribution space.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, in particular to a remote automatic locking and unlocking device for a reservoir gate. Background technique [0002] At present, the reservoir gates of all hydropower stations in China have the ability or potential for remote operation. In order to avoid accidental fall of the gate due to the failure of the steel wire rope or lifting machinery during the operation of the unit and cause power grid accidents, the method of manually inserting the locking block is usually adopted. The gate is locked. However, while increasing the insurance factor, it also caused the reservoir or power station to close the gate in an emergency, but it could not be operated remotely. The personnel had to arrive at the scene to cancel the lock, and it took a certain amount of time to arrive at the scene. At this time, it was easy Accident losses will increase. At present, the gener...

AI Technical Summary

Problems solved by technology

Although the gate itself has the function of remote operation, due to the limitation that the locking block of the gate must be manually moved on site, each operation of the gate still requires personnel to arrive at the site.

When the unit and equipment need to drop the gate immediately to shut off the water source in case of a crisis, the accident loss will be enlarged because the locking block cannot be withdrawn remotely, resulting in additional economic loss
