[0002] The changing rooms in coal mine bathhouses are equipped with manual or electric hanging clothes storage devices, but most of the existing electric changing baskets are made of plastic, and the clothes that the staff take off may be contaminated with flammable substances. Because it is a changing room, fire safety issues are more easily overlooked. Fire safety planning and infrastructure are relatively lagging behind. The construction of fire safety infrastructure is not in sync with the intelligent development of coal mines, and the supporting equipment is not perfect, so there is still a significant fire hazard. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a fire-fighting system for electric changing baskets in coal mines to solve the above problems.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A fire-fighting system for electric changing baskets in coal mines divides the ceiling of the changing room into multiple protective units. Each protective unit is equipped with multiple liftable changing baskets and a fire-fighting device, with the changing baskets arranged adjacent to each other. The fire-fighting device, including a fire detector and an automatic fire extinguisher, is suspended from the ceiling in the middle of each protective unit. A lifting drive device is fixed on the ceiling above each changing basket, and the lifting drive device is connected to the changing basket via a suspension rope. A control host is provided in the changing room, and the lifting drive device, fire detector, and automatic fire extinguisher are all electrically connected to the control host. The ceiling of the changing room is also equipped with flame-retardant top plates arranged horizontally and vertically and flush with the bottom of the changing baskets. The bottoms of the multiple changing baskets cooperate with the flame-retardant top plates to form the changing room ceiling.
[0006] Furthermore, in the above-mentioned utility model, the ceiling of the changing room and the surrounding walls of the ceiling are inlaid with a metal sealed fireproof board.
[0007] Furthermore, in the above-mentioned utility model, each of the protective units may be equipped with 4-9 changing baskets.
[0008] Furthermore, in the above-mentioned utility model content, the changing basket is made of ABS flame-retardant material.
[0009] Furthermore, in the above-mentioned utility model content, the hoisting rope is a stainless steel rope.
[0010] Furthermore, in the above-mentioned utility model content, the automatic fire extinguisher is a suspended dry powder automatic fire extinguisher.
[0011] Furthermore, in the above-mentioned utility model, the flame-retardant top plate is made of aluminum alloy.
[0012] Furthermore, in the above-mentioned utility model, the flame-retardant top plate is provided with a fan ventilation device and multiple LED lights arranged at equal intervals.
[0013] The beneficial effects of this utility model are:
[0014] When the flammable clothing being carried catches fire, the fire detector promptly detects the fire and sends a signal to the control host. The control host then lowers the electric changing basket inside the protection unit, simultaneously triggering the fire extinguisher inside the protection unit to automatically extinguish the fire, effectively preventing the fire from spreading and protecting people's lives and property. In addition, the changing basket and the flame-retardant roof itself are flame-retardant, which can effectively prevent fires from occurring. Attached Figure Description

[0020] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.
[0021] Please see the appendix Figure 1-4As shown, a coal mine electric changing room basket fire protection system can divide the changing room into multiple large areas according to the size of the site. Each area is separated by fireproof partitions so that they do not affect each other. The ceiling of each area of the changing room can be divided into multiple protective units. Each protective unit is equipped with multiple liftable changing room baskets and a fire protection device. The changing room baskets in each protective unit are arranged adjacent to each other. When the changing room baskets are at the top, the bottoms of the multiple changing room baskets can be spliced together to form the changing room ceiling.
[0022] The fire-fighting equipment is suspended from the ceiling in the middle of each protective unit. The equipment includes fire detectors and automatic fire extinguishers. Preferably, the automatic fire extinguishers are suspended dry powder automatic fire extinguishers. Each protective unit's fire detector is linked to an automatic fire extinguisher on a one-to-one basis. A lifting drive device (not shown in the attached drawings) is fixed to the ceiling above each changing basket. The lifting drive device is connected to the changing basket via a rope, and the lifting drive device moves the changing basket up and down via the rope. A control host is installed in the changing room. The lifting drive device, fire detectors, and automatic fire extinguishers are all connected to the control host. The electromechanical connection includes a dual-circuit power supply for the control host, ensuring rapid switching to the other power source in case of failure without affecting normal system operation. In the event of a power outage, the backup power supply can provide up to two hours of full-load operation. Specifically, when a fire breaks out in the changing room or flammable clothing in a protective unit catches fire, the fire detector promptly detects the fire and sends a signal to the control host. The control host then controls the lifting drive device to lower the changing basket in the corresponding protective unit, simultaneously triggering the fire extinguisher in the protective unit to spray dry powder to extinguish the fire.
[0023] The ceiling of the changing room is also equipped with flame-retardant ceiling panels arranged horizontally and vertically and flush with the bottom of the changing baskets. The flame-retardant ceiling panels are made of aluminum alloy and are spliced together with the bottom of multiple changing baskets to form the changing room ceiling.
[0024] In the above embodiments, preferably, the ceiling of the changing room and the walls surrounding the ceiling are inlaid with a sealed metal fireproof board to further improve fire resistance.
[0025] As attached Figure 2 As shown, each of the protection units can be equipped with 4-9 changing baskets. Since the protection range of the suspended dry powder automatic fire extinguisher is about 1.5 meters, and the size of the changing basket is about 550mm×550mm×800mm, it is more appropriate to set 3×3 changing baskets in each protection unit, which is exactly within the protection range of the suspended dry powder automatic fire extinguisher, maximizing the utilization efficiency.
[0026] In the above embodiments, preferably, the changing basket is made of ABS flame-retardant material, which is not only flame-retardant but also more robust. It has two layers, making it more reasonable to place items and making full use of space. The suspension rope is made of stainless steel rope. Because the suspension rope and the changing basket itself are flame-retardant, they can effectively prevent the spread of fire.
[0027] In the above embodiments, preferably, the flame-retardant ceiling is equipped with a fan ventilation device and multiple LED lights arranged at equal intervals to ensure the aesthetics and ventilation of the changing room ceiling.
