Description
Technical Field
[0001] This utility model belongs to the field of emergency fire cabinet technology, and in particular relates to a moisture-proof tunnel rescue cabinet. Background Technology
[0002] Highway tunnels are passageways specifically for automobile transportation. However, when accidents or traffic collisions occur in highway tunnels, they can easily lead to serious hazards such as fires. In such cases, it is necessary to install emergency fire cabinets inside the tunnels, which should contain commonly used fire-fighting equipment such as fire suits, fire helmets, fire boots, escape ropes, fire axes, fire extinguishers, fire hoses, and gas masks.
[0003] For example, CN215136261U discloses an emergency fire cabinet for use in highway tunnels, including a fire cabinet with an internal partition. The top two ends of the partition have mounting grooves, and the fire cabinet has a dust removal mechanism inside. The dust removal mechanism includes an adjustment mechanism, a cleaning shell, a dust collection box, a dust outlet, a suction hose, an installation pipe, an air pump, and a dust removal head. The bottom two ends of the partition have ventilation mechanisms. Since the emergency fire cabinet is in the tunnel for a long time, and the humidity in the tunnel is generally high, if these fire-fighting equipment are in a humid environment for a long time, it will affect the service life of the fire-fighting equipment. Utility Model Content
[0004] The purpose of this utility model is to provide a moisture-proof tunnel rescue cabinet. By setting up a drying chamber filled with desiccant inside the cabinet, the inside of the cabinet is kept dry during use. At the same time, through the opening, indicator light and the lifting design of the drying chamber, the moisture absorption status of the desiccant in the drying chamber can be quickly observed visually during use. This solves the problem that the service life of existing fire-fighting equipment is affected when it is in a humid environment for a long time.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0026] Please see Figure 1-2 As shown, this utility model is a moisture-proof tunnel rescue cabinet, including a cabinet 1 that stores fire-fighting equipment inside. The bottom of the cabinet 1 is fixed on a support frame 12, and a cabinet door 11 is hinged to one side of the cabinet 1. In order to prevent humid air from entering the cabinet 1 and affecting the service life of the fire-fighting equipment, this solution provides a drying chamber 2 filled with desiccant inside the cabinet 1 to absorb the moisture in the gas inside the cabinet 1.
[0027] Specifically, such as Figure 2 In this application, a support plate 22 is fixed on an inner side wall of the cabinet 1, and an elastic telescopic structure 23 is provided on the upper surface of the support plate 22. The drying chamber 2 is installed on the top of the elastic telescopic structure 23. At the same time, four openings 10 are provided vertically on the side wall of the cabinet 1 located on one side of the drying chamber 2. An indicator light 3 is provided on the top of the drying chamber 2, so that the water absorption of the desiccant in the drying chamber 2 can be judged by the number of openings 10 through the indicator light 3 during use.
[0028] It can be seen that as the amount of water absorbed by the desiccant in the drying chamber 2 increases, the overall mass of the drying chamber 2 increases, causing the drying chamber 2 to move downwards. During this downward movement, the number of openings 10 through which the indicator light 3 passes increases. In one embodiment, when the desiccant has not initially absorbed water, the bottom height of the indicator light 3 is at the top of the opening 10; when the water absorption rate of the desiccant reaches 5%, 11%, 19%, and 27%, the light emitted by the indicator light 3 passes through the first, second, third, and fourth openings 10, respectively.
[0029] Of course, in order to maintain the stability of the up-and-down movement of the drying chamber 2, two guide rails are provided vertically on the side wall of the cabinet 1 located on one side of the drying chamber 2, and a slider 24 that cooperates with the guide rails is provided on the drying chamber 2.
[0030] Meanwhile, during use, for ease of observation and to prevent humid air from entering the cabinet 1, such as... Figure 3 A flexible light-blocking plate 31 is provided on the side wall of the drying chamber 2 located below the indicator light 3. The cross-section of the flexible light-blocking plate 31 is an isosceles triangle, and the end of the flexible light-blocking plate 31 is tightly attached to the side wall of the cabinet 1. Each of the four openings 10 is sealed with a light-transmitting plate. The four light-transmitting plates are arranged from top to bottom as blue plastic / glass plate, red plastic / glass plate, green plastic / glass plate, and yellow plastic / glass plate.
[0031] Understandably, based on the above, when the desiccant's water absorption rate is less than 5%, the light emitted by indicator light 3 passes through the topmost indicator light 3, meaning that indicator light 3 is powered on at this time. Based on this, a switch structure 30 needs to be designed to control the activation of indicator light 3.
[0032] Based on this, such as Figure 4A support block 15 is installed on the inner wall of the cabinet 1 located directly above the drying chamber 2. A switch structure 30, connected in series with the power supply line of the indicator light 3 and controlling the indicator light 3 to turn on, is installed on the top of the support block 15. A control frame 32, whose end is connected to the top of the switch structure 30, is installed on the top of the drying chamber 2 and drives the switch structure 30 to retract when the drying chamber 2 descends. The switch structure 30 is connected to an inner sleeve A309. The bottom side of the inner sleeve A309 is connected to an inner sleeve B301 fitted inside it via a spring A310. The bottom side of the inner sleeve B301 is connected to an inner sleeve C302 via a spring B303. Contacts A308 and B307 are respectively provided on the inner sleeve B301 and the inner sleeve C302; when contact A308 and contact B307 are in contact, the power supply in the cabinet 1 supplies power to the indicator light 3; the open end of the inner sleeve C302 faces downward, and the open ends of the inner sleeves A309 and B301 face upward; and the elastic coefficient of spring A310 is greater than that of spring B303; when the amount of water absorbed by the desiccant in the drying chamber 2 increases and the overall mass of the drying chamber 2 increases, the drying chamber 2 moves downward. At this time, the control frame 32 drives the switch structure 30 to retract, so that contact A308 and contact B307 are in contact.
[0033] Specifically, such as Figure 4 A support ring 311 is provided at the open end of the inner sleeve C302. One side of the support ring 311 is connected to the spring B303. An insertion rod 305 is provided on the inner sleeve C302. A contact point A308 is provided at the end of the insertion rod 305. A vertical rod 304 is provided on the bottom surface of the inner sleeve B301. A slot 306 for inserting the insertion rod 305 is provided at the top of the vertical rod 304. A contact point B307 is provided at the bottom of the slot 306.
[0034] Specifically, the drying chamber 2 provided in this application is made of six perforated plates welded into a chamber-shaped structure; a doorway 21 is opened at the bottom of one side of the drying chamber 2, and a chamber door 210 is detachably installed at the doorway 21; a feeding port is opened on the perforated plate at the top of the drying chamber 2.
