[0001] The utility model relates to the technical field of electrical cabinets, and particularly relates to a fireproof electrical cabinet. Background Art
[0002] An electrical cabinet is a cabinet made of steel materials to protect components to work properly. The production materials of electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are relatively softer in material and more suitable for the production of electrical cabinets. Electrical cabinets are widely used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc.
[0003] At present, the fireproof and high-temperature resistant capabilities of electrical cabinets on the market are not good. When a fire occurs, the internal electrical appliances are easily damaged and not easy to preserve. At the same time, the electrical cabinets are relatively large in volume, occupy a large storage space, and are not easy to store. In the prior art, a fire extinguisher is used to extinguish the fire in time, but the impact force of the dry powder cannot be controlled, resulting in poor fire extinguishing efficiency, and even the situation where the fire cannot be extinguished in time.
[0004] Therefore, how to design a fireproof electrical cabinet has become a problem that needs to be solved currently. Content of the Utility Model
[0005] (1) Technical Problems to be Solved

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the utility model.
[0020] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.
[0021] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meaning of "a plurality" is two or more, unless otherwise specifically defined.
[0022] As Figures 1-4 shown, the present utility model provides a technical solution: a fireproof electrical cabinet, including a cabinet body 1 and a fire extinguisher disposed inside the cabinet body 1. A linear lead screw module 2 is fixedly connected to an inner wall on one side of the cabinet body 1. A jacket 3 is slidably connected to the linear lead screw module 2. A plurality of connecting columns 301 are fixedly connected to the side wall of the jacket 3. A spray pot 302 is fixedly connected to the end of the connecting column 301. A plurality of inclined spray nozzles 303 are provided on the outer peripheral wall of the spray pot 302. A plurality of middle spray nozzles 304 are also formed in the middle of the spray pot 302. A sealing column 305 penetrates through the middle of the spray pot 302. One end of the sealing column 305 is embedded and connected inside the jacket 3. The other end of the sealing column 305 is fixedly connected to a sealing disc 306. A feed pipe 307 is fixedly connected to the spray pot 302. A hose is connected between the feed pipe 307 and the fire extinguisher;
[0023] A left - right transverse movement assembly is provided on the inner wall of the cabinet body 1. A guide block 4 is fixedly connected to the outer wall of the sealing column 305. The left - right transverse movement assembly is used to control the transverse reciprocating movement of the guide block 4.
[0024] Specifically: An open fire and smoke alarm are provided inside the electrical cabinet. When detecting open fire or smoke, at this time, the fire extinguisher is controlled to open through an electric control unit such as a relay. The dry powder moves along the path of the hose and the spray pot 302. Thus, the dry powder is ejected from the inclined spray nozzles 303 and the middle spray nozzles 304. At the same time, the linear lead screw module 2 moves up and down, driving the spray pot 302 to move synchronously, thereby increasing the range of dry powder spraying and improving the fire extinguishing effect.
[0025] The left - right horizontal movement component includes an oblong - shaped guide groove 401. At both ends of the inner wall of the guide groove 401, grooves 402 are provided. Springs are arranged in the grooves 402, and the ends of the springs are fixedly connected with arc - shaped blocks 403.
[0026] Specifically: when the spray bottle 302 moves downward, the guide block 4 moves along the right - hand path of the guide groove 401. At this time, the sealing column 305 is in the right - most state, so that the sealing disc 306 can block the middle spray port 304, and then improve the impact force of the inclined spray port 303, enhancing the fire - extinguishing effect.
[0027] When the guide block 4 moves upward, the guide block 4 moves along the left - hand path of the guide groove 401. At this time, the middle spray port 304 and the inclined spray port 303 spray dry powder synchronously to carry out large - range fire - extinguishing work.
[0028] Among them, during the process of the guide block 4 moving from the left side to the right side of the guide groove 401, the arc - shaped block 403 is elastically displaced downward under force, providing space for the right - hand movement of the guide block 4 and limiting the guide block 4 through the plane of the arc - shaped block 403 to ensure that the guide block 4 can stably move downward in the right - hand path. The process of the guide block 4 moving from the right side to the left side of the guide groove 401 is the same as the above working principle and will not be elaborated here.
[0029] It should be noted that: when a fire occurs in the electrical cabinet, the fire point is usually on the circuit components on the horizontal plane. Therefore, by enhancing the impact force of the inclined spray port 303, the fire - extinguishing efficiency for the circuit components can be improved.
[0030] The working process of the present utility model: when detecting open fire or smoke, at this time, the fire extinguisher is controlled to open through an electronic control unit such as a relay. The dry powder moves along the path of the hose and the spray bottle 302, so that the dry powder is sprayed out from the inclined spray port 303 and the middle spray port 304. At the same time, the linear lead screw module 2 moves up and down, driving the spray bottle 302 to move synchronously, thereby increasing the range of dry - powder spraying and enhancing the fire - extinguishing effect.
[0031] And when the spray bottle 302 moves downward, the guide block 4 moves along the right - hand path of the guide groove 401. At this time, the sealing column 305 is in the right - most state, so that the sealing disc 306 can block the middle spray port 304, and then improve the impact force of the inclined spray port 303, enhancing the fire - extinguishing effect.
[0032] When the guide block 4 moves upward, the guide block 4 moves along the left - hand path of the guide groove 401. At this time, the middle spray port 304 and the inclined spray port 303 spray dry powder synchronously to carry out large - range fire - extinguishing work.
[0033] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variation thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
[0034] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
