[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] Example 1

[0034] Reference Figure 1-6 , an automatic fire extinguishing system, comprising:

[0035] A fire cabinet 1 is provided with two movable doors 2 on one side of the fire cabinet 1 through a hinged structure, which is convenient for a user to open or close the fire cabinet 1 for maintenance or replacement of a fire extinguishing agent storage tank 8; two fire extinguishing agent storage tanks 8 are placed inside the fire cabinet 1 for storing a fire extinguishing agent, wherein the fire extinguishing agent is heptafluoropropane; container valves 9 are detachably provided at the bottle mouths of the two fire extinguishing agent storage tanks 8, and the design of the container valves 9 makes it easy to disassemble and replace the new fire extinguishing agent storage tanks 8 when the fire extinguishing agent needs to be replaced, and an electromagnetic drive device is integrated in the container valve 9 for controlling the start or close of the container valve 9.

[0036] One end of each container valve 9 is fixedly connected to a pressure-resistant hose 11, and the other end of the pressure-resistant hose 11 is fixedly connected to a nozzle 10; these two nozzles 10 are fixedly passed through one side of the fire cabinet 1 so that fire extinguishing agent can be sprayed through the nozzles 10 when needed.

[0037] In order to ensure the stability of the fire extinguishing agent storage tank 8 in the fire cabinet 1, the system is also designed with two sets of fixing components; each set of fixing components includes two fixing brackets 14 fixedly installed on the inner wall of one side of the fire cabinet 1; the fire extinguishing agent storage tank 8 is located between the two fixing brackets 14; between the two fixing brackets 14, there is an arc-shaped fixing plate 12, which is in close contact with the outer wall of the fire extinguishing agent storage tank 8 to provide stable support; two fixing holes 13 are provided inside the arc-shaped fixing plate 12, and the two fixing holes 13 are respectively located near the two ends of the arc-shaped fixing plate 12; at the same time, a through hole 15 is provided inside the two fixing brackets 14, and a clamping column 16 is slidably penetrated in each through hole 15, and one end of the two clamping columns 16 cooperates with the fixing hole 13 to complete the fixing of the arc-shaped fixing plate 12;

[0038] In order to ensure that the clamping column 16 can be automatically reset, a tension spring 17 is sleeved on the outer wall of the two clamping columns 16, one end of the tension spring 17 is fixedly connected to the outer wall of the clamping column 16, and the other end is fixedly connected to one side of the fixing bracket 14; in addition, an inclined surface is provided on the end of the two clamping columns 16 close to the arc-shaped fixing plate 12, so that when the arc-shaped fixing plate 12 approaches the clamping column 16, the inclined surface will squeeze the clamping column 16 backward, thereby facilitating the clamping column 16 to be stuck into the fixing hole 13, thereby completing the rapid fixation of the arc-shaped fixing plate 12.

[0041] The present application can be used in the field of fire extinguishing technology for mining machinery and equipment, and can also be used in other fields applicable to the present application.

[0042] Example 2

[0043] refer to Figure 2 , 6 , based on the improvement of Example 1: a pipeless automatic fire extinguishing system, which is applied to the field of fire extinguishing technology of mining machinery and equipment;

[0044] In order to facilitate the user to operate the card column 16, an extension plate 18 is fixedly installed on one side of the two card columns 16, and the extension plate 18 is used to extend the card column 16 so that the user can more conveniently move the card column 16; at the same time, a limit column 19 is fixedly installed on one side of the two extension plates 18, and a limit hole 20 is opened inside the two fixed brackets 14. The limit column 19 slides with the corresponding limit hole 20, which can improve the stability of the movement of the extension plate 18.

[0045] In order to facilitate the installation of the T-shaped plate 3 , two installation holes 7 are provided on both sides of the fire cabinet 1 , and these installation holes 7 can provide additional installation positions for the T-shaped plate 3 .

[0046] In addition, in order to ensure that the arc-shaped fixing plate 12 is not prone to shaking after installation, the cross-sections of the fixing hole 13, the through hole 15 and the clamping column 16 are all designed to be rectangular; such a design can effectively prevent the arc-shaped fixing plate 12 from shaking or loosening after being fixed.

[0047] However, as is well known to those skilled in the art, the working principles and wiring methods of the control box 6 and the container valve 9 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0048] The working principle and use process of the present technical solution are as follows: when in use, the user can install the fire cabinet 1 on mining machinery and equipment, and ensure that the nozzle 10 is facing the mechanical parts that are prone to fire, such as the engine, battery compartment, etc., and ensure that the temperature detector 4 and the smoke detector 5 can perform good sensing detection on the parts and their surroundings; when a fire occurs, the temperature detector 4 and the smoke detector 5 can detect the temperature and smoke generated by the flame, and control the start of the fire extinguishing system through the control box 6. At this time, the container valve 9 opens, and the fire extinguishing agent inside the fire extinguishing agent storage tank 8 will be sprayed out from the nozzle 10, which can extinguish the flame in front; at the same time, the control box 6 is connected to an emergency start switch, and the user can also manually start the fire extinguishing system through the switch to ensure that the fire can be extinguished quickly in the early stage of the fire and reduce losses; the control box 6 is also connected to the external fire control room and alarm equipment, which can provide emergency assistance to staff in the event of a fire. Provide timely and effective alarms to facilitate timely control of fire conditions; when the internal fire extinguishing agent of the fire extinguishing system is used up or is about to exceed the shelf life, the fire extinguishing agent storage tank 8 needs to be replaced. When replacing, the user needs to move the extension plates 18 on both sides to disengage the clamping column 16 from the fixing hole 13. At this time, the arc-shaped fixing plate 12 can be removed to release the restriction on the fire extinguishing agent storage tank 8. After the fire extinguishing agent storage tank 8 is replaced, the user can again clamp the arc-shaped fixing plate 12 on one side of the fire extinguishing agent storage tank 8, push the arc-shaped fixing plate 12 and make the inside of the arc-shaped fixing plate 12 close to the fire extinguishing agent storage tank 8. At the same time, the outside of the arc-shaped fixing plate 12 needs to be close to the two fixing brackets 14 until the arc-shaped fixing plate 12 abuts against the two clamping columns 16. The two clamping columns 16 are squeezed and retreat until the fixing hole 13 is aligned with the through hole 15. The two clamping columns 16 will be clamped into the fixing hole 13 under the action of the corresponding tension spring 17 to complete the fixation of the arc-shaped fixing plate 12.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
