Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator fire escape device.

[0002]

[Prior Art]

 Due to the rapid development of commerce and industry, the population is concentrated in the city, and the city develops toward the sky. Therefore, the evacuation problem at the time of a fire in a high-rise building has become important every day. There are various inventions regarding evacuation equipment for high-rise buildings, but there is no one that is definitely safe and commonly used. To find out the cause: 1. The equipment occupies a large space and the cost is high.

2. It is necessary to receive sufficient training on how to use it, otherwise it will not be possible to achieve its efficacy temporarily. Alternatively, the operation method is complicated and causes a problem in an emergency, resulting in an unexpected accident.

3. The effect is insufficient and many people cannot be evacuated quickly at the same time. Or, it is not possible to perform normal maintenance sufficiently and is prone to failure in an emergency.

[0005]

[Problems to be solved by the device]

 Elevators are transportation equipment that can be quickly moved up and down in a building. However, as a general rule, use is prohibited in the event of a fire. The main cause is due to the following various factors.

1. There is a possibility of an unexpected power failure, and there is a danger of being stopped on the way.

2. People in the lower ranks (lower than the fire-occupied rank) also board the trains properly, which takes time and often exceeds the capacity.

3. The elevator case cannot be insulated and fireproof, which causes an unexpected disaster.

[0009] 4. Elevator gates are airtight, fireproof, and smoke may enter.

5. Since new air cannot be supplied to the inside of the elevator, smoke invasion and suffocation are likely to occur.

[0011]

[Means for Solving the Problems]

 Although the present invention is the fastest means of transportation in a building, it is regrettable that it cannot exert the effect of evacuation in the event of a fire, so we spare no installation cost and time and carry out painstaking research design. After conducting a number of case studies, we finally completed a fire evacuation system using an elevator. As a result, even in the event of a building fire, the elevators can be safely used to quickly withdraw residents in the higher floors (hierarchical fire level and above).

In other words, the present invention overcomes the unsafe factors one by one with one complete system based on the above-mentioned unsafe factors, which were banned in the event of an elevator fire, Therefore, even if the elevator is in a fire, it will be a safe and reliable facility for quick evacuation.

The apparatus will be described in detail below; After the fire level receives a signal via the alarm, the operation power of the floor is automatically cut off and the elevator stops at the level immediately below the fire level. (The resident will evacuate to the bottom by the elevator that stays on the lower floor because of the safety.) This will save the time for ascending and descending and prevent congestion, so that the high-migrants can be safely evacuated.

2. There is a dedicated motor in the elevator operation room that automatically activates at the same time as the fire alarm is activated, and prevents the elevator from being disabled even if the normal power supply is switched immediately and the normal power supply suddenly shuts off.

3. The narrow layer of the iron plate case of the elevator is made of heat insulation and insulating material, which can avoid the high temperature and electric shock inside the box.

[0016] 4. The elevator entrance and exit gates on each floor of the building will be fireproof and airtight to prevent fire and smoke from entering the pits of the calender.

5. An air filter supply device is attached to the elevator case to supply sufficient air into the case and prevent smoke from entering.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block system diagram of a system device of the device of the present invention.

FIG. 2 is an explanatory perspective view of the device of the present invention.

In the figure, 1 is a fire alarm system, 11 is a fire detector, 12 is a fire alarm general panel, 13 is a fire hierarchy (point) signal, and 14 is a fire building and a point indicator lamp.

Reference numeral 2 is an elevator control system, and 21 is an elevator hierarchical stop / selection control box of the present invention.

3 is an elevator-dedicated motor added by the present invention, 31 is an automatic start switch of a generator, and 32 is an elevator power automatic changeover switch.

Reference numeral 4 is an elevator, 41 is a heat insulating and insulating device attached to the narrow layer of the case copper plate of the present invention, 42 is an elevator gate, and 43 is a gap airtight packing of the gate 42.

Reference numeral 5 is an air filtration supply device of the present invention, and 51 is a switch for switching between the air filtration supply device and the fan.

Reference numeral 6 is a stainless steel fireproof airtight gate at the entrance and exit of each level elevator of the present invention, and 61 is a fireproof airtight packing in the clearance around the gate.

Reference numeral 7 is an elevator control room located at the highest level.

When a fire occurs, the fire detector 11 sends a signal to the fire alarm general panel due to smoke, a fire, or an abnormal rise in temperature, and the panel selects and emits a fire hierarchy (point) signal 13 Also activate the bell and indicator light. At this time, the fire occurrence point (layer) of all buildings is known.

The present invention utilizes this fire hierarchy signal 13 to directly input to the computer system 2 of the elevator. Then, by using the elevator floor stop control switch of the present invention, the elevator does not stop at the floor where the fire occurred, and stops at the floor immediately below it. Therefore, time can be saved and building residents can be evacuated without fail. At the same time, this signal 13 operates the start switch of the elevator dedicated generator 3 immediately after the computer system 2 to operate. After it stabilizes, the power supply switch 32 automatically operates and the elevator is switched to the dedicated generator power supply. Therefore, it is not affected by the sudden power failure of the normal power supply. At the same time, after the input of this signal 13, the changeover switch 51 of the air filtration feeder 5 of the present invention is operated so that the air in the box is taken from the original fan by the air filtration feeder. As a result, smoke can escape and avoid coughing or suffocation. In addition to this, according to the present invention, a packing 41 for heat insulation and insulation is packed in a narrow layer of the copper plate of the elevator case to prevent heating or electric shock inside the box. Also, the elevator entrance / exit gate 42 is packed with insulating packing even in a narrow space, and packing 43 is also installed in the gap between the gates. At the same time, a fireproof airtight gate 6 is attached to the elevator entrance and exit gates of each floor, and a fireproof airtight packing 61 is also attached around the gates to prevent smoke from entering the elevator pit.

The above-described series of devices is the equipment and devices for fire evacuation using the elevator according to the present invention.

[0031]

[Effect of the device]

 1. The fire alarm system and the elevator are necessary facilities for the building, and the present invention directly operates the one-line safety device designed by the present invention after importing the fire system into the computer control system of the elevator. Is.

2. The elevator, which was originally prohibited from use in the event of a fire, is replaced with a fire evacuation facility, which is most suitable for use by residents.

3. In the event of a fire, the elevator can be evacuated to a large number of personnel by simply stopping it at the level immediately below the fire level, ensuring safety, speedy rescue, large loading capacity, and rapid evacuation. When a resident above the fire level does not use the elevator or the computer does not respond, it is automatically switched and operated with normal hands. Being an elevator, this is really an optimal evacuation facility.

4. The safety is especially high after passing through the single-system safety device of the present invention.
