Technical Field

[0001] The utility model relates to the technical field of automatic fire extinguishing, in particular to a dual-detection mechanical automatic fire extinguishing device. Background Technique

[0002] At present, in places such as electrical cabinets, cable trenches, air compressors, etc., the commonly used automatic fire extinguishing devices are mainly divided into two types: electronic and pure mechanical. The electronic automatic fire extinguishing device relies on live equipment for driving and detection and requires an external power supply to work properly. However, in extreme environments such as high temperature, high humidity, and high corrosion, electronic circuits and electrical components may short-circuit due to aging, thus triggering a fire risk. In addition, electronic fire extinguishing devices without safety standard certification cannot be used underground in shaft mines, which limits their application scope.

[0003] Compared with the electronic automatic fire extinguishing device, the mechanical automatic fire extinguishing device uses a fire detection tube for detection. Although this fire detection tube automatic fire extinguishing device is a passive and non-electric fire extinguishing equipment, under conditions such as high temperature, friction, and vibration for a long time, the fire detection tube is prone to aging and cracking, resulting in false triggering or air leakage. In addition, the presence of the fire detection tube may also hinder the disassembly and maintenance of the protected equipment, bringing certain troubles to the maintenance and management of the equipment.

[0004] Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop a dual-detection mechanical automatic fire extinguishing device. Content of the Utility Model

[0005] The utility model provides a mechanical automatic fire extinguishing device, which solves the problems that the fire detection tube is prone to aging in high-temperature areas and the detection sensitivity is not high.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] A technical solution of a dual-detection mechanical automatic fire extinguishing device includes an area with long-term high temperature and an area prone to catching fire. An air-driven pilot starter is installed in the area with long-term high temperature, and a fire detection tube end plug is arranged in the area prone to catching fire. A fire detection tube is connected to the fire detection tube end plug, the fire detection tube is connected to a fire detection ball valve, the fire detection ball valve is connected to a medicine bottle assembly, the air-driven pilot starter is connected to the medicine bottle assembly. The medicine bottle assembly includes a medicine bottle, a medicine outlet is arranged at the top of the medicine bottle, and the medicine outlet is connected to a medicine pipeline. The medicine pipeline is distributed in the area with long-term high temperature and the area prone to catching fire, and a plurality of spray heads are installed on the medicine pipeline.

[0008] As a preferred technical solution, the pneumatic pilot starter includes a housing. A blocking block is provided at the end of the housing. A temperature-sensitive block is arranged outside the blocking block. A tail rod passes through the blocking block. A spring is sleeved outside the tail rod. An exhaust alignment device is arranged inside the housing. The end of the tail rod is connected to a striker. The tail end of the housing is connected to a diaphragm disc, and a diaphragm is arranged inside the diaphragm disc.

[0009] As a preferred technical solution, a mechanical ball valve is installed at the top of the medicine bottle, and the mechanical ball valve is communicated with the fire detection ball valve. A mechanical emergency start button is arranged between the mechanical ball valve and the fire detection ball valve.

[0010] As a preferred technical solution, the tail end of the mechanical ball valve is connected to a manual starter through a connecting pipe, and the manual starter is communicated with the pneumatic pilot starter through a pipeline.

[0011] As a preferred technical solution, a pressure gauge is installed on the medicine bottle.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The present utility model is a double-detection mechanical automatic fire extinguishing device. Through the application of the pneumatic pilot starter and the fire detection tube in different areas, a double-detection mechanism is formed, effectively improving the detection sensitivity and reliability of the automatic fire extinguishing device. In an environment where high temperature is likely to be maintained for a long time, the pneumatic pilot starter can work stably and reliably, avoiding aging problems caused by high temperature. In an area prone to fire, the fire detection tube can quickly detect the fire source and start the fire extinguishing procedure.

[0018] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0019] like Figures 1 - 3 As shown, the utility model provides a technical solution of a dual-detection mechanical automatic fire extinguishing device: it includes a long-term high-temperature area 1 and a fire-prone area 3, a pneumatic pilot starter 2 is installed in the long-term high-temperature area 1, a fire-prone area 3 is provided with a fire detection tube end plug 4, a fire detection tube 7 is connected to the fire detection tube end plug 4, the fire detection tube 7 is connected to a fire detection ball valve 8, the fire detection ball valve 8 is connected to a medicine bottle assembly, the pneumatic pilot starter 2 is connected to the medicine bottle assembly, the medicine bottle assembly includes a medicine bottle 14, a medicine outlet 11 is provided on the top of the medicine bottle 14, and the medicine outlet 11 is connected to a medicine pipeline 6, the medicine pipeline 6 is distributed in the long-term high-temperature area 1 and the fire-prone area 3, and a plurality of nozzles 5 are installed on the medicine pipeline 6.

[0020] Among them, the pneumatic pilot starter 2 includes a shell, a stop block 201 is arranged at the end of the shell, a temperature sensing block 202 is arranged outside the stop block 201, a tail rod 203 is passed through the stop block 201, a spring 204 is arranged outside the tail rod 203, an exhaust corrector 205 is arranged in the shell, a striker 206 is connected to the end of the tail rod 203, a diaphragm disk 208 is connected to the tail end of the shell, and a diaphragm 207 is arranged inside the diaphragm disk 208.

[0021] Among them, a mechanical ball valve 9 is installed on the top of the medicine bottle 14, and the mechanical ball valve 9 is connected to the fire detection ball valve 8, and a mechanical emergency start button 10 is arranged between the mechanical ball valve 9 and the fire detection ball valve 8.

[0022] Among them, the tail end of the mechanical ball valve 9 is connected to a manual starter 15 through a connecting pipe, and the manual starter 15 is communicated with the pneumatic pilot starter 2 through a pipeline.

[0023] Among them, a pressure gauge 12 is installed on the medicine bottle 14.

[0024] In this embodiment, the pneumatic pilot starter 2 and the fire detection tube 7 jointly detect the fire. Among them, when the temperature sensing block 202 of the pneumatic pilot starter 2 detects high temperature, the blocking block 201 inside it expands due to heat, and then pushes the tail rod 203 to move outwards, so that the firing pin 206 pierces the diaphragm 207, causing the air pressure inside the diaphragm disc 208 to drop rapidly. At this time, the medicine inside the medicine bottle 14 quickly sprays out from the nozzle 5 through the medicine pipeline 6 to extinguish the fire. When the fire detection tube 7 detects a flame, it quickly ruptures and sprays the internal medicine from the nozzle 5 to achieve fire extinguishing. The mechanical ball valve 9 opens after receiving the trigger signal from the fire detection ball valve 8, so that the medicine inside the medicine bottle 14 can flow out through the mechanical ball valve 9 and spray out from the nozzle 5 through the medicine pipeline 6. When manual startup of the device is required, the mechanical emergency startup button 10 can be pressed or the manual starter 15 can be operated to open the mechanical ball valve 9, thereby starting the fire extinguishing program. The pressure gauge 12 of the device can display the internal pressure of the medicine bottle 14 in real time, facilitating the user to understand the working state of the device.

[0025] By setting the manual starter 15 and the mechanical emergency startup button 10, the fire extinguishing device can be manually started in an emergency, enhancing the emergency response ability of the device. The installation of the pressure gauge 12 facilitates the user to monitor the pressure inside the medicine bottle 14 at any time to ensure the normal operation of the device. At the same time, the design of the hoop 13 ensures the stable installation of the medicine bottle 14, preventing the medicine bottle 14 from loosening or shifting due to vibration or external force.

[0026] This device improves the accuracy and reliability of detection through the dual detection mechanism of the pneumatic pilot starter 2 and the fire detection tube 7. At the same time, through the settings of the mechanical ball valve 9 and the manual starter 15, an alternative manual startup plan is provided, enhancing the practicability of the device. The device has a simple structure and is easy to install, is suitable for various places requiring automatic fire extinguishing, and has a broad application prospect.

[0027] The working principle and usage process of the present utility model:

[0028] Automatic startup mechanism: When a fire breaks out or there is abnormally high temperature before a fire, the fire detection tube 7 or the pneumatic pilot starter 2 is affected by the high temperature. The fire detection tube 7 is heated and ruptured, or the temperature-sensitive block 202 of the pneumatic pilot starter 2 is melted by heat. Under the push of the spring 204, the striker 206 pierces the diaphragm 207, causing the gas in the detection pipeline to be released. This process causes the air pressure imbalance between the upper and lower layers inside the bottle head valve on the upper part of the medicine bottle 14. The piston inside the bottle head valve is pushed open by the air pressure inside the medicine bottle, and the bottle head valve is opened. Subsequently, the medicine in the medicine bottle 14 is pushed by the driving gas, transported through the medicine outlet 11 and the medicine pipeline 6 to the nozzle 5 and sprayed out to achieve the fire extinguishing function.

[0029] Manual startup operation: Once a fire or abnormally high temperature is found on-site, the operator can immediately manually pull out the safety pin on the manual starter and press the manual startup button. This operation will release the gas inside the startup pipeline, thereby causing the air pressure imbalance inside the bottle head valve on the upper part of the medicine bottle 14, resulting in the piston inside the bottle head valve being pushed open and the bottle head valve being opened. Subsequently, the medicine in the medicine bottle 14 is pushed by the driving gas, transported through the medicine outlet 11 and the medicine pipeline 6 to the nozzle 5 and sprayed out to achieve the fire extinguishing function.

[0030] Mechanical emergency startup measure: In specific situations, if the fire extinguishing device cannot be started to release the medicine by both automatic and manual startup methods, the on-site operator can take mechanical emergency startup measures. The specific operations include pulling out the safety of the mechanical emergency startup button of the bottle valve group and manually pressing the mechanical emergency startup button. This operation will cause the air pressure imbalance inside the bottle head valve on the upper part of the medicine bottle 14, the piston inside the bottle head valve is pushed open, and the bottle head valve is opened. Subsequently, the medicine in the medicine bottle 14 is pushed by the driving gas, transported through the medicine outlet 11 and the medicine pipeline 6 to the nozzle 5 and sprayed out to achieve the fire extinguishing function.
