[0044] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0045] Example:

[0046] like Figure 1 As shown, an embodiment of the present application discloses an automatic fire extinguishing device for a mining vehicle, which is used to automatically extinguish a fire on an engine. Its specific structure includes: a medicine bottle 1, a solenoid valve 2, a delivery pipeline 3, a plurality of nozzles 4, a plurality of temperature sensors 5 and a controller 6.

[0047] The agent bottle 1 is installed directly above the engine; the agent bottle 1 is laterally installed on a crossbar directly above the engine through a support frame, and is used to store fire extinguishing agent; the fire extinguishing agent can be water-based, ultrafine dry powder or perfluorohexanone, etc., without specific limitation, and can be adjusted accordingly according to the type of fire, and it can be specifically used to extinguish Class A, Class B and Class E fires.

[0048] The solenoid valve 2 includes: a main valve body 21, which has an input connector 211 and an output connector 212, and the input connector 211 is connected to the bottle mouth of the medicine bottle 1; the input connector 211 and the output connector 212 are connected through the main passage inside the main valve body 21, and there is a valve core in the main passage; when controlled, the main passage can be cut off or connected by electromagnetically driving the valve core to move.

[0049] One end of the delivery pipeline 3 is connected to the output connector 212 for delivering the fire extinguishing agent to each nozzle 4; the delivery pipeline 3 is sheathed with a wear-resistant flame-retardant sheath to avoid being burned in a fire, thereby ensuring the use effect and extending the service life.

[0050] Several nozzles 4 are arranged around the engine and are all connected to the delivery pipeline 3 for spraying fire extinguishing agent toward the engine when a fire occurs; dustproof protective caps are installed at the ends of the nozzles 4 to adapt to use under harsh working conditions and avoid blockage.

[0051] A number of temperature sensors 5 are installed around the engine to collect temperature information around the engine in real time, and use this as a basis for judging whether a fire has occurred; specifically, K-type thermocouples, digital temperature detectors, temperature sensing cables or temperature sensing optical fibers and other components can be used, without specific limitation, and corresponding adjustments can be made.

[0052] The controller 6 has an input end electrically connected to a plurality of temperature sensors 5, and an output end electrically connected to the main valve body 21; it can obtain the real-time temperature value collected by the temperature sensor 5, and open the main valve body 21 when the real-time temperature value is greater than a preset value; the preset value can be 120°C, 140°C, 160°C or 180°C, without specific limitation, and can be adjusted and designed according to actual vehicle conditions; it can be connected to the vehicle battery to draw power, and can also be equipped with a battery.

[0053] Exemplarily, the temperature sensor 5 and the controller 6 are electrically connected through a trigger line, which ensures the stability of signal transmission, is not easily interfered by the external environment, and improves the reliability of the device.

[0054] It should be noted that the medicine bottle 1, the nozzle 4, and the pipeline connector are all made of metal material, preferably 304 stainless steel, which ensures the use effect at high temperature and improves the operation stability of the device.

[0055] When a fire occurs in the engine of the mining vehicle, the temperature sensor 5 sends the collected real-time temperature value to the controller 6. The controller 6 determines that the real-time temperature value is greater than the preset value, and then opens the main valve body 21, so that the input joint 211 is connected to the output joint 212, thereby enabling the fire extinguishing agent in the medicine bottle 1 to be transported to the nozzle 4 through the delivery pipeline 3 and finally sprayed toward the engine to automatically perform the fire extinguishing operation.

[0056] The utility model continuously collects the real-time temperature value through the temperature sensor 5, and then opens the main valve body 21 after the controller 6 determines that the real-time temperature value is greater than the preset value, so that the fire extinguishing agent in the medicine bottle 1 is fully sprayed around the engine through the delivery pipeline 3 and the nozzle 4. It extinguishes thoroughly, comprehensively without dead corners, without omission and is automatically operated, reacts in time, does not delay the initial rescue time, can extinguish the fire at the first time when the fire occurs, reduces the possibility of danger, and protects the safety of the driver and the mining vehicle.

[0057] In some embodiments, as Figure 1 shown, it further includes: an audible and visual alarm 7, which is electrically connected to the output end of the controller 6; the audible and visual alarm 7 is installed beside the engine, outside the cab or other positions of the vehicle, without specific limitation, and can be adjusted accordingly.

[0058] During operation, when the controller 6 opens the main valve body 21, it will also simultaneously start the audible and visual alarm 7, and the audible and visual alarm 7 will flash and emit an alarm sound to remind the driver and the people around the vehicle that a fire has occurred in this vehicle.

[0059] By setting the audible and visual alarm 7, it plays a role in timely reminding of the fire, so that the driver and the people around the vehicle can escape or carry out rescue in the first time, improving the safety.

[0060] In some embodiments, as Figure 1 shown, it further includes: a remote starter 8, which is arranged in the cab and is electrically connected to the input end of the controller 6.

[0061] Exemplarily, the remote starter 8 and the controller 6 are electrically connected through a start line, which ensures the stability of signal transmission, is not easily interfered by the external environment, and improves the reliability of the device.

[0062] When the controller 6 receives the start signal from the remote starter 8, the main valve body 21 will be opened.

[0063] By setting the remote starter 8, the driver can extinguish the fire in the cab in the first time. Thus, in the case of accidental failure of the automatic fire extinguishing, remote manual start is realized, which plays a role of backup remedy guarantee, improves the reliability of the device, and ensures the fire extinguishing effect.

[0064] Based on the above embodiments, the remote starter 8 includes: a start button 81 and an indicator light 82; wherein, the start button 81 is used to send a start signal to the controller 6 after being manually pressed; the indicator light 82 is used to light up after the start button 81 is pressed.

[0065] Through the above settings, it is convenient for the driver to operate, ensures quick use in emergency situations, prevents delay in rescue, and gives start feedback through the indicator light 82, which plays a reminder role and prevents the situation where the start fails but the driver is still unaware.

[0066] In some embodiments, as Figure 1 shown, the solenoid valve 2 further includes: a manual switch 22, which is arranged on the main valve body 21 and is used to manually open the main valve body 21.

[0067] When a fire occurs in the engine of the mining vehicle, the driver can drive the spool in the main valve body 21 through the manual switch 22, so as to manually open the main valve body 21, and the device starts to carry out the fire extinguishing operation.

[0068] By setting the manual switch 22, the main valve body 21 can be manually and mechanically started, ensuring that the fire extinguishing measures can still be started in case of emergencies such as power failure of the equipment, circuit breakage or damage of control components. It provides additional safety guarantee and enables the device to be reliably put into use when necessary.

[0069] In some embodiments, as Figure 1 shown, the main valve body 21 further has a bypass joint 213, and a pressure gauge 9 is connected in butt joint with the bypass joint 213.

[0070] Specifically, the main valve body 21 is a three-way valve, the main passage inside it is in a T-shaped structure, and is respectively connected to the input joint 211, the output joint 212 and the bypass joint 213, and the spool is in the central area of the main passage. Therefore, the three can be cut off or connected at the same time.

[0071] Through the above settings, after the fire extinguishing device is started, the internal pressure of the medicine bottle 1 can be reflected in real time. Based on this, the remaining amount of the fire extinguishing agent can be conveniently judged, and other fire extinguishing measures can be carried out in time.

[0072] In some embodiments, such as Figure 1 shown, the conveying pipeline 3 includes: a main pipeline 31 and a plurality of branch pipelines 32; wherein, one end of the main pipeline 31 is connected and communicated with the output joint 212, one ends of the plurality of branch pipelines 32 are all connected and communicated with the main pipeline 31, and the other ends are correspondingly connected and communicated with the nozzles 4 one by one.

[0073] In case of a fire, the fire extinguishing agent first enters the main pipeline 31, then is conveyed to the corresponding output joint 212 through each branch pipeline 32, and finally is sprayed onto the engine.

[0074] Through the above settings, it is convenient for the laying of the pipeline, reduces the installation difficulty, and improves the conveying efficiency of the fire extinguishing agent, thereby improving the fire extinguishing effect.

[0075] In the description of the present utility model, a large number of specific details are illustrated. However, it can be understood that the embodiments of the present utility model can be practiced without these specific details. In some instances, well-known methods, structures and technologies are not shown in detail so as not to obscure the understanding of this specification.
