Description

Technical Field

[0001] The utility model relates to a manual automatic striker type driver, belonging to the technical field of energy storage fire fighting. Background Art

[0002] With the maturity of battery energy storage technology, battery pack energy storage is becoming increasingly popular in energy storage power stations. Currently, energy storage technology is widely used in fields such as new energy vehicle energy storage power stations. However, with the construction and application of energy storage power station projects, its fire hazards are gradually becoming apparent. The difficulty in firefighting energy storage power stations lies primarily in extinguishing fires in the power batteries inside. Judging from the current development trend of energy storage, the batteries used in energy storage are still mainly lithium-ion batteries. Once thermal runaway occurs, lithium-ion batteries will quickly spread and some may even explode. Therefore, once an emergency situation is confirmed, firefighting procedures must be quickly initiated. Currently, the industry's fire extinguishing devices with firing pin actuators are basically automatically activated by signals, and after activation, it is impossible to observe and confirm whether they have been punctured, thereby screening out defective products. Therefore, the development of a manual automatic firing pin actuator is very necessary. Utility Model Content

[0034] While working:

[0035] During the automatic puncture process, the external detector is connected to the manual automatic firing pin driver via a communication connector 15. When the detector senses a fire, it outputs a dry contact signal to the manual automatic firing pin driver, igniting the gunpowder 16. The gas entering through the inlet 18 expands and pushes the firing pin 6 to puncture the puncture plate 8. The firing pin limit barb 10 hooks onto the puncture plate 8 and prevents it from rebounding. The inlet 18 and outlet 20 of the manual automatic firing pin driver are connected through the guide port 13. The position of the firing pin 6 can be seen through the viewing window 12, thereby determining whether the puncture has occurred.

[0036] During the manual puncture process, when a fire is detected, the operator removes the retaining ring 2 and manually presses the manual button 1, which pushes the firing pin 6 downward to puncture the puncture piece 8. The firing pin retaining barb 10 hooks onto the puncture piece 8 and does not rebound. The inlet 18 and outlet 20 of the manual automatic firing pin driver are connected through the guide port 13. The position of the firing pin 6 can be seen through the viewing window 12, and the puncture is determined by the position of the firing pin 6.

[0037] By designing a manual button 1, it is convenient to manually open it in an emergency, avoiding the situation where the firing pin 6 cannot pierce the puncture piece 8 when the automatic start mode fails, shortening the timeliness of fire fighting and improving fire fighting efficiency; by adding the design of the window 12 hole, the actual position of the firing pin 6 can be directly observed, and then whether the firing pin 6 pierces the puncture piece 8 can be confirmed, which is simple and clear and convenient for the next step of operation; by adding the limiting barb 10, the occurrence of rebound after the firing pin 6 pierces the puncture piece 8 is effectively avoided.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
