Description

Novel Fire lift

Technical field

The utility model relates to a kind of elevator, particularly a kind of novel Fire lift.

Background technology

The fire-fighting function of existing elevator lags behind the modern science and technology standard, only at the fireman's switch of artificial shake-up base station or after control cabin sends the fire-fighting instruction, elevator just stops nearby and returns the base station, elevator opens the door and enters the fire fighter and rescue state then, therefore, this kind mode does not possess the function of rapid evacuation building interior personnel when fire.Therefore, the elevator of existing design normally transports personnel at ordinary times, and when the building presence of fire, a large amount of personnel are badly in need of rapid evacuation, and elevator is at this moment because supply disconnecton and out of service, thereby causes serious accident to take place.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of novel Fire lift, with realize accurately, fire protection warning and operation timely, avoid the generation of great personnel casualty accidents.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of novel Fire lift comprises power-supply system, is installed in the control unit in the machine room, and by the car of described control unit control and be arranged on the Room door of every floor, described car is installed in the hoistway by guide rail, and described Room door is fire protection gate;

In the doorframe of the described Room door of every floor alarm module is installed all;

The breather port place of described well headroom is equipped with alarm module;

In the described machine room alarm module is installed;

Described alarm module all is connected to described control unit by the CAN bus;

Also is furnished with the lithium cell group that is connected with described power-supply system.

Preferably, described alarm module comprises smoke sensing device and Water Temperature Sensor, and described smoke sensing device and Water Temperature Sensor all are connected to described control unit by the CAN bus.

By technique scheme, the novel Fire lift that the utility model provides, it can realize timely, the accurately warning of fire by being arranged at the alarm module in Room door, hoistway and the machine room; Room door is set to fire protection gate, can rely on the protection of fire protection gate to make personnel or goods and materials arrive at safety zone by the scene of fire fast; By standby lithium cell group, the elevator that causes because of the building power fail in the time of can effectively avoiding fire is out of service, thereby avoids unnecessary injures and deaths to occur.

Description of drawings

In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below.

Fig. 1 is the connection structure scheme drawing of the disclosed novel Fire lift of the utility model embodiment.

The specific embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.

According to Fig. 1, the novel Fire lift that the utility model provides comprises power-supply system, is installed in the control unit in the machine room, and by the car of control unit control and be arranged on the Room door of every floor, car is installed in the hoistway by guide rail, and Room door is fire protection gate; In the doorframe of the Room door of every floor smoke sensing device and Water Temperature Sensor are installed all, the breather port place of well headroom is equipped with smoke sensing device and Water Temperature Sensor, smoke sensing device and Water Temperature Sensor equally also are installed in the machine room, and smoke sensing device and Water Temperature Sensor all are connected to control unit by the CAN bus.

Principle of the present utility model is:

The all Room doors of elevator all adopt fire protection gate, smoke sensing device and Water Temperature Sensor all are housed in the doorframe of every layer of Room door, smoke sensing device and Water Temperature Sensor are housed in the breather port of well headroom and the machine room equally, the induced signal of smoke sensing device and Water Temperature Sensor all by the CAN bus transfer to control unit;

When normally using elevator, in case smog or the temperature that exceeds standard arranged, the normally closed point of smoke sensing device and Water Temperature Sensor disconnects at once, and elevator changes the fire-fighting operation automatically over to; During fire-fighting, at first squeeze in the cab outdoors in the Room and send audible and visible alarm, the interior choosing of fire layer begins to flash rapidly, outer the calling together no longer of this layer responds, all all eliminate outside the blanking base station in all, outer the calling together all of all irrevocable base stations all eliminated, and elevator stops nearby, as do not have this layer and return the base station, call together outward and do not open the door; Return in the way as no full signal then responds and returns the outer of base station and call together, otherwise directly return the base station, the people is put in arrival base station back pullout (BPO), does not namely stop midway and directly open the floor of calling together outside having farthest; As no full signal, then response is outer calls together, otherwise directly returns during backhaul, wait for again and rescue the people, the smoke sensing device in well headroom or machine room and Water Temperature Sensor action, elevator is eliminated all outer calling together, sound and light alarm stops, and returns at once, and rescue finishes after elevator reaches the base station; If fireman's switch action during this then enters the fire fighter and rescues state, the base station is returned in interior choosing that can corresponding non-fire floor and calling together outward no longer automatically, and after the smoke sensing device in well headroom or the machine room and Water Temperature Sensor moved, the elevator action logic was the same; Except the base station, the user specifies a floor standby at least, as the base station condition of a fire is arranged, and then another floor is as the alternative base station of escape layer; The protocol code of this system CAN bus is in open state, and any control unit all can not have to authorize to be accepted;

Cause the oppressive unsafe condition of Denging because of the building power fail when avoiding fire, the utility model is equipped with the lithium cell group of different size; Just often the elevator feedback electric energy is preserved in the lithium cell group, charge capacity reaches 90% when above, automatically switches to normal lithium cell group operation, and elevator changes the power supply of lithium cell group into; Lithium cell group electric weight drops to 50% and transfers normal operating condition when following to; Behind the grid power blackout, whether no matter be the fire rescue state, transfer the emergency cell operation immediately to, 50% charge capacity can guarantee elevator operation one hour, charge capacity is down to 10% when following, and the elevator state is identical with the smoke sensing device in well headroom or the machine room or Water Temperature Sensor action; Behind the power system restoration, it is that 50% back is out of service as early as possible with battery charge to charge capacity that the special charging module will cooperate electric energy feedback module, and elevator enters normal operating condition.

The Fire lift that this utility model provides is compared elevator of the same type and be can save energy more than 20%, and can save energy consumption for cooling greatly, really becomes the energy-saving safe elevator.

Multiple modification to above-described embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.
