Abstract
The invention belongs to the technical field of electric control locks, and provides a ventilation pavilion shutter electric control lock capable of preventing misoperation and a working method thereof.The ventilation pavilion shutter electric control lock comprises a lock sleeve, a lock shell, a lock cylinder, a moving disc, an upper cover and a lower cover, and is characterized in that the lock sleeve is fixed to the lock shell, and the lock cylinder capable of freely rotating is arranged in the lock sleeve; the lower cover is matched with the lock sleeve through a hole, and a manual shifting rod is arranged on the lock cylinder. By means of ingenious cooperation of the electromagnet shifting fork, the manual shifting rod, the moving disc, the lock cylinder, the rotating hook, the pin shaft, the compression spring and the tension spring, the blind window can be smoothly closed, the closed state can be kept, and terrorist damage can be prevented; and after the alarm condition is relieved, the worker can conveniently open the blind window again by using a key on site, so that ventilation in the tunnel is ensured. When the blind window is opened, the blind window is kept in an open state under the action of the moving disc, the rotating hook, the pin shaft and the pressure spring, and the open state can be kept.
Description
technical field [0001] The invention relates to the technical field of electric control locks, in particular to an electric control lock for ventilation pavilion shutters for preventing misoperation and a working method thereof. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] At present, more and more urban high-voltage cables are arranged underground. In order to ensure ventilation and safety in power tunnels, a ventilation pavilion is installed at certain distances to ventilate the tunnel to ensure the oxygen content in the tunnel and the discharge of toxic and harmful gases. To ensure that the environment in the tunnel is normal, so as to ensure the stable operation of the entire city's power transmission. [0004] At present, the electronic control lock of the ventilation booth can control the opening and closing of the blinds, and can be manual...
