DETAILED DESCRIPTION

[0028] 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.

[0029] Example 1

[0030] Reference Figure 1-4 , an automatic fire extinguishing system, comprising:

[0031] It includes: a water inlet pipe 2, a first liquid infusion pipe 3, a second liquid infusion pipe 4, a control box 1 and a detection component.

[0032] One end of the water inlet pipe 2 is provided with a water flow valve 6 for connecting to an external water source pipeline, and the other end is connected to the first infusion pipe 3 and the second infusion pipe 4 through a three-way pipe. The first infusion pipe 3 is equipped with a plurality of first atomizing nozzles 8, and the second infusion pipe 4 is equipped with a plurality of second atomizing nozzles 9. These atomizing nozzles are used to spray fire extinguishing liquid to extinguish the flame.

[0033] Two fire extinguishing agent storage tanks 13 are arranged inside the control box 1, and the storage tanks are filled with fire extinguishing agent, wherein the fire extinguishing agent is specifically heptafluoropropane. A detachable bottle head connecting valve 14 is provided on the top of the fire extinguishing agent storage tank, and these connecting valves are connected with the water inlet pipe 2 through a pipeline, so that the fire extinguishing agent can smoothly enter the water inlet pipe 2.

[0034] The detection component is a key part of the system, which is used to detect fire and start the fire extinguishing system. The detection component includes a detection connecting pipe 5, on which a plurality of temperature sensors 10 are installed. The temperature sensor 10 consists of a mounting shell 11 and a temperature-sensitive fusible link 12. The temperature-sensitive fusible link 12 is fixedly connected to the mounting shell 11 and exposed to the outside world. Adjacent temperature-sensitive fusible links 12 are electrically connected. When the ambient temperature exceeds the threshold, the temperature-sensitive fusible link 12 will melt, causing the circuit to be disconnected, thereby triggering the start of the fire extinguishing system.

[0035] A mechanical control valve 15 is also fixedly installed on the top inner wall of the control box 1. The valve is connected to one end of the detection connecting pipe 5 and is electrically connected to a plurality of temperature-sensitive fusible links 12. When the temperature-sensitive fusible link 12 is blown, the mechanical control valve 15 receives a signal and operates. A high-pressure gas storage bottle 17 is also provided in the control box 1. High-pressure nitrogen is stored in the high-pressure gas storage bottle 17. The high-pressure gas storage bottle 17 is connected to the mechanical control valve 15 through a high-pressure gas storage valve 18. When the mechanical control valve 15 operates, a pin arranged at the bottom thereof pierces the diaphragm of the high-pressure gas storage valve 18 to release the high-pressure nitrogen. After the nitrogen is reduced in pressure by the pressure reducing valve 19, it is connected to the two bottle head connecting valves 14 through a pipeline, driving the fire extinguishing agent to flow out of the storage tank and enter the water inlet pipe 2.

[0036] 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.

[0037] Example 2

[0038] refer to Figure 1 , 34. Improvement on the basis of Example 1: an automatic fire extinguishing system with a pipe network, which is applied to the field of fire extinguishing technology for mining machinery and equipment;

[0039] In order to facilitate manual start-up of the fire extinguishing system, a manual switch 7 is provided outside the control box 1 , and the switch is electrically connected to the mechanical control valve 15 . When the fire extinguishing system needs to be manually started, the manual switch 7 only needs to be pressed.

[0040] In addition, in order to fix and assist in fixing the fire extinguishing agent storage tank 13, two fixing plates 21 are fixedly installed on the bottom inner wall of the control box 1, and cooperate with the inner wall of one side of the control box 1 to form two placement cavities, and an abutment plate 22 is slidably provided inside each placement cavity, and the bottom of the abutment plate 22 is connected to the bottom inner wall of the control box 1 through a spring 20. When the fire extinguishing agent storage tank 13 is placed, the abutment plate 22 will continue to abut the fire extinguishing agent storage tank 13 under the action of the spring 20, thereby completing the auxiliary fixation of the fire extinguishing agent storage tank 13; when the fire extinguishing agent storage tank 13 needs to be replaced, it is only necessary to take the tank body out of the placement cavity, and the abutment plate 22 can squeeze the spring 20 to make way, thereby providing additional space for the installation of the new tank body, making it convenient for the staff to complete the tank body replacement operation.

[0041] In a specific implementation, the first infusion tube 3 and the second infusion tube 4 are installed above the equipment to be extinguished, and the nozzles of the multiple first atomizing nozzles 8 are downward, so as to directly extinguish the flame on the equipment, while the nozzles of the multiple second atomizing nozzles 9 are respectively upward and horizontally, so as to comprehensively extinguish the flame spreading around. Such a design ensures the high efficiency and comprehensiveness of the fire extinguishing system.

[0042] However, as is well known to those skilled in the art, the working principle and wiring method of the mechanical control valve 15 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selection according to their needs or convenience.

[0043] The working principle and use process of the present technical solution are as follows: when in use, when a fire occurs in the engine or battery compartment of a mining machinery and equipment, if the temperature of the burning flame reaches 185°C, the temperature-sensitive fusible link 12 in the temperature sensor 10 can automatically melt to complete the detection of the fire; then the mechanical control valve 15 is started, and the diaphragm in the high-pressure gas storage valve 18 is pierced by the control needle. At this time, the nitrogen in the high-pressure gas storage bottle 17 will be decompressed through the pressure reducing valve 19, and finally enter the two fire extinguishing agent storage tanks 13, pressurizing the inside of the fire extinguishing agent storage tanks 13 to spray out the fire extinguishing agent inside, and the fire extinguishing agent will enter the first infusion pipe 3 and the second infusion pipe 4 through the water inlet pipe 2, and spray out through the corresponding first atomizing nozzle 8 and the second atomizing nozzle 9 to complete the extinguishing of the equipment and the surrounding flames; after the fire extinguishing agent is sprayed, the water flow valve 6 will then open and pass the water through the first atomizing nozzle 8 and the second atomizing nozzle 9. The nozzle 9 sprays on the equipment and its surroundings to complete the final cooling; the above steps can be carried out simultaneously and only take 2-6 seconds; at the same time, the system is provided with two starting modes, automatic and manual. In the early stage of the fire, the device can also be manually started by the manual switch 7, which can eliminate the fire more quickly; the fire extinguishing system needs to replace the fire extinguishing agent storage tank 13 and the high-pressure gas storage cylinder 17 after the fire extinguishing agent and the corresponding nitrogen are used up; when replacing, the user disassembles the fire extinguishing agent storage tank 13 and squeezes the abutment plate 22 down, so that there is enough space to complete the removal and replacement of the fire extinguishing agent storage tank 13. After installation, the abutment plate 22 will continue to abut the bottom of the fire extinguishing agent storage tank 13 under the action of the spring 20, so as to complete the auxiliary fixation of the fire extinguishing agent storage tank 13; after the high-pressure gas storage cylinder 17 is replaced, it is only necessary to ensure that the high-pressure gas storage cylinder 17 is stuck in the fixing clamp 16 to ensure that the installation of the high-pressure gas storage cylinder 17 is relatively stable.

[0044] 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.
