[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of the present invention.

[0022] In this document, relational terms such as "first" and "second" are used solely to distinguish one entity or operation from another, and do not necessarily require or imply any actual relationship or order between these entities or operations. Terms such as "upper," "lower," "left," "right," and "top" indicate positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0023] like Figures 1 to 3 As shown, a pressure-stored automatic fire extinguishing system includes a detection unit, which is connected to a storage unit through a first pipeline 1, and the storage unit is connected to a fire extinguishing unit through a second pipeline 2. After the detection unit is triggered, the storage unit is connected to the second pipeline 2 and releases fire extinguishing agent through the fire extinguishing unit to cool down and extinguish the fire.

[0024] A first pipeline 1 and a second pipeline 2 are provided to connect the detection unit and the fire extinguishing unit to the storage unit respectively. According to the usage scenario and installation environment of the fire extinguishing system, the detection unit and the fire extinguishing unit are arranged correspondingly to important components by changing the distribution of the first pipeline 1 and the second pipeline 2, thereby reducing space restrictions on the installation of the fire extinguishing system, adapting to the needs of temperature detection and cooling fire extinguishing, improving the sensitivity of detection response and the efficiency of cooling fire extinguishing, and improving practicality.

[0025] In the pressure-stored automatic fire extinguishing system of this embodiment, the first pipeline 1 includes several first branches, the detection unit is arranged at the end of the first branch, the second pipeline 2 includes several second branches, and the fire extinguishing unit is arranged at the end of the second branch.

[0026] Specifically, multiple detection units and fire extinguishing units are set according to the locations of components that need to be detected, thereby expanding the application range of the fire extinguishing system, improving the comprehensiveness of the fire extinguishing system, and improving the cooling and fire extinguishing efficiency.

[0027] Preferably, the first pipeline 1 and the second pipeline 2 are respectively located between the lithium battery packs in the motor host, and the detection unit and the fire extinguishing unit are respectively arranged on the peripheral sides of the lithium battery packs.

[0028] The first pipe 1 and the second pipe 2 are arranged between the lithium battery pack to protect the lithium battery. When the temperature of the components in the lithium battery pack is too high, the detection unit generates a signal and transmits it to the storage unit through the first pipe 1. The storage unit then transports the fire extinguishing agent to the fire extinguishing unit through the second pipe 2 to cool down the high-temperature location and extinguish the fire, preventing the high temperature of the lithium battery from causing damage to internal components or spontaneous combustion.

[0029] On the other hand, it is conceivable that the automatic fire extinguishing system in the present application can also be used in traditional diesel engine equipment or other mechanical equipment, and the pipelines, detection units and fire extinguishing units can be set according to the specific application scenarios.

[0030] In the pressure-stored automatic fire extinguishing system of this embodiment, the storage unit includes a nitrogen tank 3 , a container valve 4 is provided on the nitrogen tank 3 , and the first pipeline 1 and the second pipeline 2 are respectively connected to the container valve 4 .

[0031] Specifically, a container valve 4 is provided to control the sealing or release of nitrogen in the nitrogen tank 3. Under normal circumstances, the nitrogen tank 3 is isolated from the first pipeline 1 and the second pipeline 2, respectively. When the detection unit transmits a signal to the container valve 4, the nitrogen tank 3 is connected to the second pipeline 2, and the nitrogen is released into the second pipeline 2 to cool down and extinguish the high-temperature or fire location through the fire extinguishing unit.

[0032] In the pressure-stored automatic fire extinguishing system of this embodiment, the detection unit includes an automatic detector 5 and a manual detector 6 located at the end of the first pipeline 1 , and a trigger 7 is provided between the first pipeline 1 and the container valve 4 .

[0033] Specifically, an automatic detector 5 is provided to automatically detect the temperature of the lithium battery and trigger a trigger 7 to change the state of the container valve 4 when the temperature is high or a fire occurs, so that nitrogen is released to cool down and extinguish the fire; a manual detector 6 is provided as a double detection guarantee to avoid the automatic detector 5 failing to trigger the nitrogen release.

[0034] Preferably, a sealing sheet 9 is provided between the trigger 7 and the container valve 4 , a trigger needle 10 is provided on one side of the sealing sheet 9 , the trigger needle 10 is located in the trigger cavity, and the trigger cavity is connected to the outside atmosphere through an airway 11 .

[0035] A sealing plate 9 is provided to maintain the air pressure inside the container valve 4. The automatic detector 5 or the manual detector 6 pushes the trigger needle 10 through the first pipeline 1 to break the sealing plate 9 and change the pressure inside the container valve 4, so that the high-pressure nitrogen in the nitrogen tank 3 pushes the piston of the container valve 4 and enters the second pipeline 2, and is cooled and extinguished by the fire extinguishing unit.

[0036] In addition, a manual trigger structure is provided on the trigger 7, and the trigger 7 can be manually pressed to push the trigger needle 10 to break the sealing sheet 9 to release nitrogen.

[0037] The air channel 11 is provided to facilitate rapid communication between the container valve 4 and the outside world after the sealing sheet 9 is destroyed, thereby rapidly reducing the pressure, achieving smooth release of nitrogen, and improving the response speed.

[0038] Specifically, the automatic detector 5 and the manual detector 6 are respectively provided with argon tubes, and the argon tubes spray argon gas through the first pipeline 1 into the trigger 7 and push the trigger needle 10 to break the sealing sheet 9.

[0039] An argon tube is provided. When a fire occurs, the argon tube ruptures to release argon and drives the trigger needle 10 to break the sealing piece 9 to destroy the pressure in the container valve 4, thereby releasing the nitrogen in the nitrogen tank 3.

[0040] In the pressure-stored automatic fire extinguishing system of this embodiment, a temperature sensing component and a transmission component are provided in the automatic detector 5 , and the transmission component is located between the temperature sensing component and the argon gas pipe.

[0041] Specifically, the temperature sensing component includes a temperature sensing bulb, and the transmission component includes a spring. When the ambient temperature is higher than the upper limit temperature of the temperature sensing bulb, the temperature sensing bulb automatically bursts and drives the spring to pierce the argon tube, thereby releasing the argon to drive the trigger needle 10 to move.

[0042] Preferably, the automatic detector 5 and the manual detector 6 in the present application can be selected to use relevant components in the existing technology, and their specific structures are not described in detail.

[0043] In the pressure-stored automatic fire extinguishing system of this embodiment, the fire extinguishing unit includes a nozzle 8, which is located on the second pipeline 2. The high-pressure nitrogen in the nitrogen tank 3 is ejected from the nozzle 8 through the outlet of the container valve 4 and the second pipeline 2 to achieve cooling and fire extinguishing.

[0044] Specifically, after the nitrogen tank 3 is connected to the second pipeline 2, the nozzle 8 works to release the fire extinguishing agent, and the fire extinguishing agent is transported through the second pipeline 2 and sprayed by the plurality of fire extinguishing nozzles 8 in the area where the fire needs to be extinguished.

[0045] Preferably, a fire extinguishing nozzle 8 is provided corresponding to the placement area of ​​each automatic detector 5 or manual detector 6, so as to further improve the fire extinguishing efficiency and carry out targeted fire extinguishing in key areas.

[0046] In the present invention, unless otherwise clearly stipulated and limited, the terms "installation", "setting", "connection", "fixation", "rotation" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0047] Although the embodiments of the present invention have been shown and described in detail, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
