Description

Inside structure of unblanking of binary channels intelligence lock

Technical Field

The utility model relates to a well lid lock, more specifically say, it relates to an inside structure of unblanking of binary channels intelligence lock.

Background

Along with the development of modern cities, electronic control intelligent well covers are installed on a plurality of inspection wells for electric power, communication, gas, rainwater and the like, and the well covers have the functions of underground environment information monitoring, information uploading, electronic locking and the like. Compared with the traditional well lid, the electronic intelligent well lid has obvious advantages, but potential safety hazards exist in the electronic intelligent well lid cannot be ignored. When the well lid is opened and is overhauled and maintained in the pit, because of personnel's carelessness or management lack of standardization, lead to the pedestrian to miss and go into in the pit, or the maintainer is overhauld in the pit and the ground staff does not discover, the ground staff who does not notice someone in the pit at this moment closes the lock with the well lid and dies, finishes the maintenance operation. Because the inspection shaft design is generally darker, and noise such as surrounding vehicle travel, construction, when the well lid was closed, personnel in the pit shout sound was hardly perceived by personnel on the ground to cause personnel in the pit to be stranded. Because the narrow and small dark in space in pit, the air is thin, and stranded personnel are bearing huge physiology and psychological pressure in the pit, if not flee out in time, and the probability of surviving is extremely low, consequently is indispensable for the well lid escape device in intelligence well lid design.

However, the intelligent well lid in the current market has the following problems:

1. no downhole escape device:

at present, mainstream intelligent well covers in the market are not provided with an underground escape device. When underground personnel are trapped, one escape method is to call for help underground to draw attention of the personnel above the ground, so that police or other personnel are contacted to carry out unlocking operation on the ground in a remote unlocking mode and the like, the success rate of the escape method is extremely low, and the requirement on the physiological and psychological quality of the trapped underground personnel is high; another escape method is to get in touch with others through communication tools such as mobile phones and the like in the underground, but because of the signal shielding effect of the underground closed space and the iron well cover, the probability of getting in touch with the outside through the communication tools such as mobile phones and the like is extremely low, and the escape success probability is too poor; the last escape scheme is to break the lock to escape in the pit, but the electronic lock generally has the design of anti-violence disassembly, and the manual disassembly and the damage to the electronic lock in the pit can almost not be completed, so the escape probability is extremely low.

2. The underground escape device is provided, but the underground escape device is complex in operation and poor in reliability or cannot be used after power failure:

at present there are a small amount of intelligent well lids in the market to carry out the design of fleing, and the form of fleing can divide into two kinds: one is to use an underground electronic button to unlock and escape: when people are trapped underground, the trapped people press the electronic button underground, and the electronic lock can be opened without authorization, so that the underground quick escape is realized. However, the method is influenced by equipment power supply and circuit control, once the conditions of insufficient battery power or equipment circuit damage and the like occur, the escape button fails to be used, and the life safety of underground trapped personnel cannot be reliably guaranteed; the other is to use an emergency key to unlock and escape underground: when underground personnel are trapped, the portable emergency key is inserted into the underground lock hole, and the lock is unlocked through mechanical transmission under the condition that the electronic lock is not authorized. In the method, the personnel in the well needs to carry the emergency key, and the emergency key is inserted into the lockhole in the dark, so that the method has great difficulty, and after the lockset is opened, the lock shaft needs to be manually rotated to open the well cover, so that the operation is complex. In addition, if the electronic lock causes mechanical faults due to water inlet, dust inlet and the like, gear transmission is abnormal, and the emergency key cannot unlock the lock. If the personnel trapped in the pit are passerby, the personnel cannot escape from the pit because the personnel do not carry the emergency key, and the life safety of the personnel trapped in the pit cannot be guaranteed.

Therefore, no matter from personnel's life safety, still from escape device's convenience, reliability and stability, all urgently need a well lid escape device in the well, can be when personnel are stranded, and simple swift, safe and reliable opens the well lid in the pit and flee to guarantee personnel's life safety in the pit.
