Description

Hyperbaric chamber escape

Technical field

The utility model relates to escape device, particularly relates to a kind of hyperbaric chamber escape of transformer station.

Background technology

The hyperbaric chamber of transformer station, the door of high voltage distribution installation room require firm, tight, can prevent fires, open outwardly.Existing transformer substation high voltage chamber generally all fills unidirectional dead bolt mechanical lock and gate control system, and both have come in cooperation, and opening gate system is generally performed by operated from a distance or on-the-spot input password, mechanical lock then by patrol officer carry at any time key operated.The key in hyperbaric chamber at least should have 3, is responsible for keeping, according to value transfers by operations staff.One uses when specializing in urgent, specialize in operations staff for one to use, other can be lent the tour high-tension apparatus personnel through ratifying and use through the maintenance of approval, the work person in charge of construction team, but should signature be registered, make an inspection tour or returned after end-of-job the same day, must lock door conveniently when making an inspection tour high voltage distribution installation, one is prevent from toy from entering to cause ground short circuit accident; Two is prevent external staff from swarming into, and malfunction touches equipment by mistake, has an accident.Open inside the door of high voltage distribution installation room without key, only has outside enabling just palpus key, but in practical work, door in hyperbaric chamber in off position time, after there is the emergency such as fire or blast in hyperbaric chamber, can not open the door voluntarily after indoor staff is injured, and need to wait for that other staff of outside fetch standby key enabling and rescue, so just greatly delay valuable rescue time, great personal injury and economic loss is caused to power supply department, the impacting with high pressure of indoor generation is to behind the door, because door lock is unidirectional dead bolt, door can not from inside to outside be opened, the shape of door likely produces distortion, sometimes there will be the situation that key can not open door, this also brings great impact to rescue.

Utility model content

For the hyperbaric chamber door Problems existing of transformer station in above-mentioned prior art, the utility model provide a kind of rational in infrastructure, can bidirectional opening, be convenient to rescue, do not need the hyperbaric chamber escape of external force.

The technical scheme that problem to be solved in the utility model is taked is: hyperbaric chamber escape, comprise escape body and doorframe, the top edge of doorframe is provided with door-hinge spring, lock body is provided with in described escape body, electromagnetic lock and pressure sensor, lock body is provided with two-way lock tongue, it is round and smooth crossing that described two-way lock tongue has two one end, the other end is respectively to the arc surface above opened, described two-way lock tongue is connected with electric conductor by guide spring, electromagnetic lock is arranged near described electric conductor, pressure sensor connection door access control system, gate control system connects described electromagnetic lock.

The utility model has the advantages that: 1, the utility model changes the unidirectional dead bolt of the mechanical lock of original door into two-way lock tongue, more convenient escape are opened; 2, increase pressure sensor in electromagnetic lock loop, escape can be locked and gate control system by automatic opener tool after being subject to certain pressure; 3 set up door-hinge spring, after mechanical lock and gate control system are under pressure and are unlocked, automatically push escape open, prevent escape by by mistake locked.

Detailed description of the invention

In order to make those skilled in the art understand the technical solution of the utility model better, in conjunction with detailed description of the invention, the utility model is described in further detail with reference to the accompanying drawings below.

As Fig. 1, 2, shown in 3, described hyperbaric chamber escape, be arranged in hyperbaric chamber body of wall 8, it comprises escape body 1 and doorframe 4, the top edge of doorframe is provided with door-hinge spring 3(door-hinge spring and produces certain outside elastic force when escaping door lock is dead to escape), in described escape body, lock body 18 is set, electromagnetic lock 6, pressure sensor 7, lock body is provided with two-way lock tongue 5, it is round and smooth crossing that described two-way lock tongue has two one end, the arc surface (shown in Fig. 3 up time 90-degree rotation) that the other end upwards opens, described two arc surfaces contact with lock box both sides, existing outer handle 13 is also comprised in certain escape body, Internal handle 12, lock core 10 is (through outer handle after installing, lock body, lockhole 14 on Internal handle), in theft-proof bolt 16(has people to make an inspection tour in hyperbaric chamber, theft-proof bolt is generally opened), the antitheft knob 9 be connected with lock core, holding screw 11, tube connector 15 etc., theft-proof bolt 16 contacts with lock box when using, the position of the corresponding two-way tongue of described doorframe is provided with jam plate 17 and lock box 2, lock box is square groove body and is formed by doorframe, two-way lock tongue is under the state of door locking, be stuck in the correspondence position of lock box and jam plate, described two-way lock tongue is connected with electric conductor 19 by guide spring 20, described electric conductor is ferrous material, electromagnetic lock is arranged on the neighbouring relative position of described electric conductor, pressure sensor connection door access control system (electromagnetic lock controller), gate control system connects described electromagnetic lock.

When after the situations such as hyperbaric chamber breaking out of fire or blast, pressure sensor in the escape of hyperbaric chamber is after being subject to exceeding preset pressure value, send signal to gate control system, gate control system is opened, and connect electromagnetic lock loop, described electric conductor pulls two-way lock tongue to move to electromagnetic lock direction together under the effect of electromagnetic lock, thus unlatching mechanical lock, open the door even if such structure can avoid needing to find standby key after generation emergency or have standby key can not open the situation of escape.

Described door-hinge spring is to ensure at pressure sensor when being subject to exceeding preset pressure while opening gate system and mechanical lock; high pressure escape are flicked certain distance; avoid gate control system static a period of time after escape are opened, according to the defence program locked high pressure escape again of gate control system.

Above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted; although be described in detail the utility model with reference to specific embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement; and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the scope of claim of the present utility model protection.
