Description

Technical Field

[0001] The utility model relates to the technical field of automatic fire extinguishing, in particular to a fire extinguishing device which is applied to industrial and mining vehicles and can be used for zoned protection and multiple releases. Background Art

[0002] As the core equipment of industrial and mining enterprises, industrial and mining vehicles occupy a pivotal position in the production process. However, given the heat and sparks generated by friction during operation and the harsh environment in which they are located, once a fire occurs, the consequences are extremely serious. In order to prevent and control such fire risks, industrial and mining vehicles must be equipped with automatic fire extinguishing devices. However, the current automatic fire extinguishing devices on the market are often only designed to meet the single-use requirements of a single protection zone, and are insufficient for application scenarios in multiple protection zones. In a specific working environment, a single fire extinguishing may not be able to completely eliminate the source of fire, and multiple releases of fire extinguishing agents are required to ensure safety. In addition, existing fire extinguishing devices usually do not have the function of partition protection, which limits the fire extinguishing effect to a certain extent.

[0003] In view of this, in response to the above technical problems, those skilled in the art are in urgent need of developing an innovative fire extinguishing device solution, which should have the ability to provide partition protection and multiple releases of fire extinguishing agents. Such a device should be able to quickly and effectively release fire extinguishing agents (including but not limited to water-based fire extinguishing agents, ultra-fine dry powder fire extinguishing agents, and perfluorohexanone, etc.) when a fire occurs to curb the spread of the fire, thereby ensuring the safety of vehicles and personnel.

[0010] As a preferred technical solution, a pressure gauge is installed on the fire extinguishing agent tank, and the pressure gauge is used to detect the pressure of the tank.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model is a fire extinguishing device that can be used in industrial and mining vehicles for zoned protection and multiple releases. The multiple solenoid valves and nozzle components are set up to extinguish fires in specific protection areas in a targeted manner, reduce the waste of fire extinguishing agents, and improve the efficiency of fire extinguishing.

A zone 1 solenoid valve mechanical switch 111 is installed on the zone 1 solenoid valve 11, a zone 2 solenoid valve mechanical switch 131 is installed on the zone 2 solenoid valve 13, the zone 1 solenoid valve 11, the zone 2 solenoid valve 13 and the main solenoid valve 12 are connected with a control component, the control component includes a control unit 6, a battery life module 5, a manual starter 7, an audible and visual alarm 8 and a point / line temperature detector 9, the control unit 6 is connected with the battery life module 5, the manual starter 7, the audible and visual alarm 8 and the point / line temperature detector 9 in sequence through connecting lines, and a DC24 power line 4 is provided on the battery life module 5.

[0020] The installation steps are as follows:

[0021] 1. Installation and filling of fire extinguisher tanks

[0022] 1. Pour the fire extinguishing agent into the fire extinguishing tank 1, and ensure that the agent outlet is fastened through the main solenoid valve 12 connector, and the connection must ensure sealing.

[0023] 2. Install the connector between the inflation port 2 and the pressure gauge 3 on the fire extinguisher tank, and also ensure that the connection is tight and sealed.

[0024] 3. Fill the tank with nitrogen through the filling port 2, and observe the value of the pressure gauge 3 during the process. When the pressure in the fire extinguishing tank reaches the pressure design parameter of the fire extinguishing device, the filling should be stopped immediately.

[0025] 2. Assembly of the release line

[0026] 1. Use a tee to connect the zone 1 solenoid valve 11, the main solenoid valve 12 and the zone 2 solenoid valve 13. All connections must be tightened and sealed.

[0027] 2. Connect the pipelines of the assembled nozzle assembly 10 to the first zone solenoid valve 11 and the second zone solenoid valve 13 respectively, and ensure the tightness and sealing of the connection points.

[0028] 3. Assembly and connection of control device

[0029] 1. Connect the DC24V power cable 4 of the endurance module to the vehicle battery and ensure that the connection is firm.

[0030] 2. Connect the endurance module 5, control unit 6, manual starter 7, and sound and light alarm 8 in sequence, and ensure that all connections are tightened.

[0031] 3. Connect the point / line temperature detector 9 to the control unit 6, and ensure that the connection is stable and effective.

[0032] In this embodiment, when a fire occurs inside a mining vehicle, the point / line temperature detector 9 will first sense the heat generated by the fire source and transmit the signal to the control unit 6.

In addition, in order to facilitate the driver and the occupants to quickly operate in an emergency, these mechanical switches are designed to be easily accessible and operated.

[0036] The endurance module 5 provides a continuous and stable power supply for the fire extinguishing device, ensuring the reliability and stability of the fire extinguishing device during the operation of the industrial and mining vehicle. At the same time, the use of the DC24 power line 4 also improves the safety and reliability of the fire extinguishing device.
