Description
Technical Field
The invention relates to the field of elevator safety equipment, in particular to a fire-fighting device of an elevator.
Background
The chimney effect refers to the phenomenon that indoor air rises or falls along a space with a vertical slope, so that air convection is enhanced. The chimney effect is generated. In buildings and structures (such as water towers) with shared atrium, vertical ventilation (smoke exhaust) air ducts, staircases and the like with similar chimney characteristics, namely, with unobstructed circulation space from bottom to top, air (including smoke) is diffused or exhausted out of the buildings quickly along a channel under the action of density difference.
The elevator shaft of an elevator is a typical building with a chimney effect. Elevators are widely used in high-rise buildings. Once a fire breaks out in a high-rise building, the ascending air flow of the fire due to the chimney effect is easily diffused into the whole building, and greater danger is generated. Meanwhile, air temperature regulation in high-rise buildings requires a large amount of air conditioners for temperature regulation, and a large amount of energy is consumed.
In conclusion, the invention aims to solve the problem of how to produce the fire-fighting device of the elevator, which can assist the high-rise building in temperature adjustment, reduce energy consumption and simultaneously protect the high-rise building from fire spreading due to chimney effect.
Disclosure of Invention
The invention aims to provide a fire-fighting device of an elevator, which can assist high-rise buildings in temperature adjustment and energy consumption reduction and simultaneously protect the high-rise buildings from fire spreading due to chimney effect.
In order to realize the purpose of the invention, the invention adopts the following technical scheme:
the utility model provides a fire control unit of elevator, includes the well, its characterized in that, the well inner wall has the gradual little inclination from bottom to top, the well inner wall is equipped with the water pipe, the connection of water pipe both ends bury underground in the water tank of well below, the water pipe is sealed by multisection water pipe subsection, water pipe subsection surface interval is provided with the shower nozzle.
The inclination enables the chimney effect in the shaft to be strengthened, namely strong convection is formed in the high-rise building by taking the shaft as the center, air is driven by the chimney effect in the shaft from the bottom of the high-rise building to be sent out from the top of the shaft, and air freshness in the high-rise building is guaranteed. The water pipe arranged on the inner wall of the well is used as a heat dissipation device with a chimney effect on one hand, so that the heat in the water pipe is taken away by the ascending air flow in the well, and the temperature in a high-rise building is reduced; on the other hand, the water pipe cooperation the shower nozzle can be when the conflagration takes place the water spray right the well carries out the fire control cooling, prevents that the spark from being brought to other parts of high-rise building by updraft. The water pipe sections are convenient to replace when the sections are damaged.
Preferably, the water pipe section comprises an inner shell and an outer shell sleeved outside the inner shell, and the ends of the inner shell and the outer shell are sealed to form a closed cavity.
The closed chamber may be used to contain an energy storage material.
Preferably, an energy storage material is encapsulated in the closed cavity.
The energy storage material is a solid-liquid phase change material, the solid-liquid phase change material is liquefied and absorbs heat when the environment is higher than the phase change temperature of the solid-liquid phase change material, and is solidified and releases heat when the environment is lower than the phase change temperature of the solid-liquid phase change material, so that the temperature of air in the hoistway is controlled at the phase change temperature of the solid-liquid phase change material, and if the solid-liquid phase change material with the phase change temperature of 18-25 ℃ is adopted, the air sent to a high-rise building due to a chimney effect can be controlled to be at a comfortable temperature, and the energy consumption of an air conditioning system.
Preferably, the water tank further comprises a radiator, and the radiator is exposed at the bottom of the well.
The water tank is buried underground at the bottom of the well and can absorb heat energy on the shallow ground, and at the moment, the heat energy collected by the water tank is dissipated into the well by the radiator. The chimney effect is enhanced by providing more heat for the bottom of the well, the air flowing speed in the high-rise building is enhanced, and the temperature adjusting effect of the chimney effect is improved.
Preferably, a heat dissipation cavity is arranged in the radiator, and the heat dissipation cavity is communicated with the inside of the water tank to form the same space.
The heat dissipation chamber can be full moisture in the water tank makes moisture in the water tank with heat dissipation chamber fully contacts, increases the heat dissipation chamber absorbs the thermal speed of water tank guarantees to last high-efficiently to the well energy supply.
Preferably, a circulating pump is arranged at the joint of the water tank and one end of the water pipe.
The circulating pump drives water in the water tank to circulate in the water pipe, and on one hand, the water flows to continuously send the heat dissipation cavity into the heated water in the water tank; on the other hand, the water pipe is heated, the energy storage material in the closed cavity absorbs heat and changes phase to be liquefied through hot water, so that the energy storage material continuously absorbs heat in the well, and the possibility of fire hazard can be reduced due to lower temperature while temperature is adjusted.
Preferably, a monitoring device is arranged in the well, and the monitoring device comprises a temperature sensor, a smoke sensor and a wireless signal transmitter.
The monitoring device monitors whether a fire condition exists in the well through the temperature sensor and the smoke sensor, and the wireless signal transmitter sends out a signal to control the sprayer according to a measured result.
Preferably, the spray head comprises a spray nozzle, a solenoid valve and a wireless signal receiver.
The wireless signal receiver receives a control signal of the wireless signal transmitter, and drives the electromagnetic valve to open the nozzle to spray water in the water pipe when a fire occurs, and the sprayed water cools the well to reduce air flow of a chimney effect and prevent the spread of the fire on one hand; on the one hand, the flame entering the well is extinguished.
Preferably, an opening is formed at the top of the hoistway.
The opening provides an effective airflow outlet for the airflow of the chimney effect when the air purifier is used at ordinary times, so that the airflow can flow rapidly.
Preferably, the opening is provided with an electrically controlled door.
The electric control door is controlled to be closed when a fire disaster happens, an upward passage of the well is blocked, namely, air flowing in the well is cut off, a chimney effect is blocked, and the hidden danger that flames are carried and diffused by ascending air flow in the well is eliminated.
The invention has the advantages of high-efficiency temperature regulation, energy conservation, effective prevention of fire and reduction of loss caused by the fire.
