Description

TECHNICAL FIELD

[0001] The utility model relates to the lock of energy storage cabinet, concretely is a kind of energy storage cabinet emergency unlocking mechanism. BACKGROUND

[0002] At present, the existing energy storage cabinet is generally provided with electronic lock and the like lock to ensure the safety of energy storage cabinet. Such energy storage cabinet, such as the authorized announcement number CN217509220U disclosed in Chinese patent document, authorized announcement date 2022.09.27, utility model name "energy storage cabinet"; but when partial small-scale spontaneous combustion explosion and the like accident occurs in the energy storage cabinet, a large amount of heat and high-temperature high-pressure gas will be generated, which cannot be released in time, and the internal pressure of the energy storage cabinet will rapidly increase, which has the risk of explosion. At this time, the door of the energy storage cabinet needs to be opened quickly to release the internal pressure and avoid the expansion of danger. However, the existing electronic lock and the like lock is easy to be damaged under high temperature and high pressure, and cannot work normally, which causes the door of the energy storage cabinet cannot be opened, and the internal pressure cannot be released in time, which has great safety hazard. Therefore, a new type of emergency unlocking device is needed, which can drive the mechanical mechanism by using the high-pressure gas generated inside when small-scale spontaneous combustion explosion and the like accident occurs in the energy storage cabinet (small-scale spontaneous combustion explosion in the energy storage cabinet will produce airflow fluctuation to cause the sensor of electronic equipment in the energy storage cabinet to fail, so it is difficult to trigger the opening of the cabinet door by the lock and the sensor of electronic equipment), to realize the ejection unlocking of the lock, so as to open the door of the energy storage cabinet, release the internal pressure in time, and avoid the expansion of danger. SUMMARY

[0003] To overcome the above shortcomings, the utility model aims to provide an energy storage cabinet emergency unlocking mechanism for automatically opening and closing the cabinet door in emergency state, which solves the technical problems that it is difficult to automatically unlock and open the door of energy storage cabinet when small-scale spontaneous combustion explosion occurs in the existing similar energy storage cabinet, release the internal pressure in time, and avoid the expansion of danger. The purpose is realized through the following technical scheme.

[0004] An emergency unlocking mechanism for an energy storage cabinet, characterized by comprising a gas collection mechanism and an actuator, is installed at the lock of the cabinet door. The actuator's extended part connects to the unlocking part of the lock. The gas collection base of the gas collection mechanism is semi-circular, with a gas collection membrane on one side of the circular opening at the top. A through hole is provided on one side of the membrane. The actuator is located at the opening at the bottom of the gas collection base, and is connected to the through hole in the gas collection base via an air pipe. The actuator is a pry bar-driven unlocking device. A pump body is located on one side of the gearbox. A vent on one side of the pump body is connected to one end of the air pipe via a quick connector. Another quick connector at the other end of the air pipe is connected to the opening at the air collection seat of the air collection mechanism. A vent on the other side of the pump body is connected to the exhaust pipe via another quick connector. The air collection membrane of the air collection mechanism is fixed to the top circular opening of the air collection seat via an air collection cover. Two ends of a compression spring inside the air collection seat abut against the air collection membrane and the bottom of the air collection seat, respectively. A pry bar pushes one end of the unlocking device's pry bar out of the gearbox. A torsion spring is located on the pry bar, which serves as the actuator of the actuator mechanism. Thus, the exhaust pipe extends out of the corresponding energy storage cabinet and discharges high-pressure gas. The high-pressure gas collected by the air collection mechanism is linked to the lock of the corresponding energy storage cabinet via the pry bar of the actuator mechanism, achieving the unlocking of the lock, automatic opening of the cabinet door, and timely release of high-pressure gas.

[0005] The pump body of the lever-driven unlocking device is equipped with an eccentric wheel and a check plate. One end of the check plate is fixed in the pump body, and the other end of the check plate abuts against the outer diameter of one side of the eccentric wheel to prevent backflow. The central shaft of the eccentric wheel passes through the pump body and is connected to the driving wheel in the gearbox. When the driving wheel meshes with the first driven wheel and the second driven wheel, one end of the gear shaft of the second driven wheel is equipped with a cam, and one side of the cam abuts against the other end of the lever in the gearbox.

[0006] The outer diameter of the eccentric wheel is provided with at least three equidistant blades. One side of the blades is sealed by abutting against the inner wall of the vent hole at two adjacent quick connectors on one side of the pump body through the eccentrically set central shaft on the eccentric wheel. A check valve is provided at the pump port on that side of the pump body. Check grooves are provided at the blades on the outer diameter of the eccentric wheel corresponding to the check valves. When the eccentric wheel reverses, the check grooves abut against and limit the check valves.

[0007] The actuator may be a cylinder-driven unlocking device. A quick connector at one end of the air pipe connects to one end of a cylinder plug, and the other end of the cylinder plug connects to the cylinder body. The cylinder plug at the connection point is equipped with a second sealing ring. A spring is installed on the outer diameter of one end of the piston rod inside the cylinder, extending out of the cylinder body. A first sealing ring is installed at the other end of the piston rod, sealing against the inner wall of the cylinder body. The two ends of the spring respectively abut against an exhaust port at one end of the cylinder body and the end of the piston rod. The extended piston rod serves as the actuator of the actuator mechanism. Thus, the piston rod extending out of the cylinder body is linked with the lock of the corresponding energy storage cabinet, realizing the ejection and unlocking of the lock, automatic opening of the cabinet door, and timely release of high-pressure gas.

[0008] The gas collection membrane of the gas collection mechanism is either convex or concave.

[0009] This utility model has a reasonable structural design and a unique unlocking method that uses high-pressure gas inside the energy storage cabinet. The high-pressure gas inside the cabinet is easily recovered and discharged, which improves the safety and stability of the energy storage cabinet and facilitates automatic unlocking in the event of localized small-scale spontaneous combustion or explosion inside the cabinet. It is suitable for use as an emergency unlocking mechanism for energy storage cabinets and for structural improvements to similar products. Attached Figure Description

[0022] The structure and use of this utility model will now be further described with reference to the accompanying drawings. Figures 1-8 In the first embodiment shown, the emergency unlocking mechanism includes an air collection mechanism 19 and an actuator 20. The emergency unlocking mechanism is installed at the lock of the cabinet door. The actuator extends out and is connected to the unlocking part of the lock. The air collection base 15 of the air collection mechanism is semi-circular. An air collection membrane 17 is provided on one side of the circular opening at the top of the air collection base. A through hole 1701 is provided on one side of the membrane of the air collection membrane. An actuator is provided at the opening at the bottom of the air collection base. The actuator and the through hole at the air collection base of the air collection mechanism are connected by an air pipe 14. The aforementioned actuator is a pry bar-driven unlocking device. A pump body 4 is provided on one side of the gearbox of the actuator. One side air hole of the pump body is connected to one end of the air pipe through a quick connector 5. Another quick connector at the other end of the air pipe is connected to the opening of the air collection seat 15 of the air collection mechanism. The other side air hole of the pump body is connected to the exhaust pipe through another quick connector. The air collection membrane of the air collection mechanism is fixed to the top circular opening of the air collection seat through the air collection cover 18. The two ends of the compression spring 16 inside the air collection seat abut against the air collection membrane and the bottom of the air collection seat, respectively. One end of the pry bar 11 of the pry bar-driven unlocking device extends out of the gearbox. A torsion spring 13 is provided at the pry bar. The extended pry bar is the actuator of the actuator.

[0023] The aforementioned gearbox includes an upper gear cover 9 and a lower gear cover 1. The pump body of the pry bar-driven unlocking device is equipped with an eccentric wheel 3 and a check plate 12. One end of the check plate is fixed to the pump body, and the other end abuts against one side of the outer diameter of the eccentric wheel to prevent backflow. The central shaft of the eccentric wheel passes through the pump body and connects to the driving wheel 6 inside the gearbox. Simultaneously, the driving wheel meshes with the first driven wheel 7 and the second driven wheel 8. One end of the gear shaft of the second driven wheel is equipped with a cam 10, one side of which abuts against the other end of the pry bar inside the gearbox. The outer diameter of the eccentric wheel has at least three equidistant blades 301. One side of these blades abuts against the inner wall of one side of the vent hole at two adjacent quick-connect fittings inside the pump body via the eccentrically positioned central shaft on the eccentric wheel. The check plate is located at the pump inlet on that side of the pump body. Check grooves 302 are respectively provided at the blades on the outer diameter of the eccentric wheel corresponding to the check plate. When the eccentric wheel reverses, the check grooves abut against and limit the check plate. The gas-collecting membrane of the aforementioned gas-collecting mechanism is either convex or concave.

[0024] According to the gas collection mechanism structure of Embodiment 1 above, as follows Figures 9-10 In the second embodiment shown, the actuator may be a cylinder-driven unlocking device. The quick connector at one end of the air pipe is connected to one end of the cylinder plug 26, and the other end of the cylinder plug is connected to the cylinder body 21. The cylinder plug at the connection is provided with a second sealing ring 25. A spring 22 is provided on the outer diameter of the rod of one end of the piston rod 23 inside the cylinder and extends out of the cylinder body. A first sealing ring 24 is provided at the other end of the piston rod. The first sealing ring abuts against the inner wall of the cylinder body for sealing. The two ends of the spring abut against the exhaust hole at one end of the cylinder body and the end of the piston rod, respectively. The extended piston rod is the actuator of the actuator mechanism.

[0025] Based on the structural designs of Embodiments 1 and 2 above, the gas collection mechanism includes Scheme 1 and Scheme 2, and the actuator includes Scheme 1 and Scheme 2. Their specific structures are as follows:

[0026] Option 1 for the air collection mechanism: The air collection membrane is convex. Air pressure impacts the air collection membrane, compressing it and causing it to indent downwards to collect air. Then, a compression spring rebounds the air collection membrane to its initial position, and the resulting pressure difference is balanced through the through-holes in the air collection membrane. By repeatedly compressing and rebounding the air collection membrane, air pressure is collected, thus achieving the effect of collecting air pressure.

[0027] Option 2 for the air collection mechanism: a concave air collection membrane. Air pressure impacts the air collection membrane, causing it to vibrate up and down and collect air. The pressure difference generated during the air collection process is balanced through the through-holes in the air collection membrane. By repeatedly vibrating the air collection membrane, air pressure is collected, thus achieving the effect of collecting air pressure.

[0028] Option 1 for the actuator: A pry bar pushes the unlocking device, and air pressure enters the pump body to drive the eccentric wheel to rotate. The eccentric wheel and blades are integrally formed. The blades open as the distance between them and the pump body increases, and close as the distance between the eccentric wheel and the pump body decreases. The gas is discharged to the outside of the energy storage cabinet through the exhaust pipe (this is the key to generating the pressure difference). A check plate prevents the eccentric wheel from reversing. The gear assembly in the gearbox, consisting of the driving wheel, the first driven wheel, and the second driven wheel, increases the driving force. The gear assembly then drives the cam, which pushes the pry bar. The pry bar unlocks the actuator, and the pry bar is reset by a torsion spring.

[0029] Option 2 for the actuator: The cylinder pushes the unlocking device. Air pressure enters the cylinder and pushes the piston rod, which unlocks the actuator and is then reset by a spring.

[0030] In summary, this emergency unlocking mechanism has advantages such as low cost, smooth unlocking, and safety and reliability, ensuring the safety of the energy storage cabinet in emergency situations, especially ensuring the safety of the energy storage cabinet in the event of a small spontaneous combustion explosion inside the cabinet.
