Description

Technical Field

[0001] The present invention relates to a lock for an energy storage cabinet, specifically an emergency unlocking device for an energy storage cabinet. Background Art

[0002] At present, locks such as electronic locks are generally installed inside existing energy storage cabinets to ensure the safety of the energy storage cabinets. For such energy storage cabinets, as disclosed in the Chinese patent document with the authorized announcement number CN217509220U, the authorized announcement date is September 27, 2022, and the utility model name is "Energy Storage Cabinet"; however, when an accidental situation such as a local small spontaneous combustion and explosion occurs inside the energy storage cabinet, a large amount of heat and high-temperature and high-pressure gas will be generated. These high-temperature and high-pressure gases cannot be released in time, which will cause the internal pressure of the energy storage cabinet to rise rapidly, posing a risk of explosion. At this time, it is necessary to quickly open the energy storage cabinet door to release the internal pressure and prevent the danger from expanding. However, existing locks such as electronic locks are easily damaged in a high-temperature and high-pressure environment and cannot work properly, resulting in the inability to open the energy storage cabinet door, the inability to release the internal pressure in time, and posing a great potential safety hazard. Therefore, a new type of emergency unlocking device is needed, which can, when an accidental situation such as a small spontaneous combustion and explosion occurs inside the energy storage cabinet (a small spontaneous combustion and explosion inside the energy storage cabinet will cause air flow fluctuations, resulting in the failure of the electronic device sensors inside the energy storage cabinet, making it difficult to trigger the opening of the cabinet door through the lock and the electronic device sensors), use the high-pressure gas generated inside to drive a mechanical mechanism to achieve the ejection and unlocking of the lock, thereby opening the energy storage cabinet door, releasing the internal pressure in time, and preventing the danger from expanding. Summary of the Invention

[0003] To overcome the above deficiencies, the purpose of the present invention is to provide to the art an emergency unlocking device for an energy storage cabinet that facilitates the automatic opening and closing of the cabinet door in an emergency state, so as to solve the technical problem that it is difficult to automatically unlock and open the energy storage cabinet door in time to release the internal pressure and prevent the danger from expanding when a small spontaneous combustion and explosion occurs inside existing similar energy storage cabinets. Its purpose is achieved through the following technical solutions.

[0004] An emergency unlocking device for an energy storage cabinet, the key point of its structural design is that the emergency unlocking device includes an air intake mechanism and an actuating mechanism. The emergency unlocking device is installed at the lock of the cabinet door. The actuating member protruding from the actuating mechanism is connected to the unlocking member of the lock. The air intake seat of the air intake mechanism is semicircular. An air intake film is provided on one side of the circular opening at the top of the air intake seat. A through hole is provided on one side of the film of the air intake film. An actuating mechanism is provided at the orifice at the bottom of the air intake seat. The actuating mechanism is connected to the through hole at the air intake seat of the air intake mechanism through an air pipe. The actuating mechanism is a pry bar pushing unlocking device. A pump body is provided on one side of the gear box of the actuating mechanism. One ventilation hole of the pump body is connected to one end of the air pipe through a quick connector. The other quick connector at the other end of the air pipe is connected to the orifice at the air intake seat of the air intake mechanism. The other ventilation hole of the pump body is connected to an exhaust pipe through another quick connector. The air intake film of the air intake mechanism is fixed to the circular opening at the top of the air intake seat through an air intake cover. The two ends of the compression spring in the air intake seat abut against the air intake film and the inner bottom of the air intake seat respectively. One end of the pry bar of the pry bar pushing unlocking device protrudes from the gear box. A torsion spring is provided on the pry bar. The protruding pry bar is the actuating member of the actuating mechanism. Thus, the exhaust pipe protrudes out of the corresponding energy storage cabinet and discharges high-pressure gas. The high-pressure gas collected by the air intake mechanism is linked with the lock of the corresponding energy storage cabinet through the pry bar of the actuating mechanism, realizing the ejection and unlocking of the lock, the automatic opening of the cabinet door and the timely release of high-pressure gas.

[0005] An eccentric wheel and a check valve are provided in the pump body of the pry bar pushing unlocking device. One end of the check valve is fixed in the pump body. The other end of the check valve abuts against the outer diameter of one side of the eccentric wheel for check. The central axis of the eccentric wheel passes through the pump body and is connected to the driving wheel in the gear box. The driving wheel meshes with the first driven wheel and the second driven wheel at the same time. One end of the gear shaft of the second driven wheel is provided with a cam. One side of the cam abuts against the other end of the pry bar in the gear box.

[0006] At least three equally spaced blades are provided on the outer diameter of the eccentric wheel. One side of the blade abuts against and seals the inner wall of the ventilation hole at one of the two adjacent quick connectors on one side in the pump body through the eccentrically arranged central axis on the eccentric wheel. The check valve is arranged at the pump port at this side of the pump body. Check grooves are respectively provided at the positions of the blades on the outer diameter of the eccentric wheel corresponding to the check valve. When the eccentric wheel rotates in reverse, the check grooves are abutted and limited by the check valve.

[0007] The actuator is a cylinder-driven unlocking device. One end of the air pipe is connected to one end of the cylinder plug through a quick connector. The other end of the cylinder plug is connected to the cylinder block. A second sealing ring is provided on the cylinder plug at the connection. A spring is provided on the outer diameter of the rod part at one end of the piston rod in the cylinder block and extends out of the cylinder block. A first sealing ring is provided at the end of the other end of the piston rod. The first sealing ring abuts against the inner wall of the cylinder block for sealing. The two ends of the spring respectively abut against an exhaust hole at one end in the cylinder block and the end of the piston rod. The extended piston rod is the actuator of the actuator mechanism. Thus, one end of the piston rod extending out of the cylinder block is linked with the lock of the corresponding energy storage cabinet, realizing the ejection and unlocking of the lock, the automatic opening of the cabinet door, and the timely release of high-pressure gas.

[0008] The air collection film of the air collection mechanism is convex or concave.

[0009] The structure of the present invention is reasonably designed. The unlocking method through high-pressure gas in the energy storage cabinet is special.

[0022] Now, in combination with the drawings, the structure and use of the present invention will be further described. As shown in Figures 1 - 8 Embodiment 1, the emergency unlocking device includes an air intake mechanism 19 and an actuating mechanism 20.

One side air hole of the pump body is connected to one end of the air pipe through a quick connector 5. The other quick connector at the other end of the air pipe is connected to the orifice at the air intake seat 15 of the air intake mechanism. The other side air hole of the pump body is connected to the exhaust pipe through another quick connector; the air intake film of the air intake mechanism is fixed to the circular opening at the top of the air intake seat through an air intake cover 18. Both ends of the compression spring 16 in the air intake seat are respectively abutted against the air intake film and the inner bottom of the air intake seat; one end of the pry bar 11 of the pry bar push unlocking device extends out of the gearbox. A torsion spring 13 is provided at the pry bar. The extended pry bar is the actuating member of the actuating mechanism.

[0023] The above gearbox includes a gear upper cover 9 and a gear lower cover 1. An eccentric wheel 3 and a check valve piece 12 are provided in the pump body of the pry bar actuated unlocking device. One end of the check valve piece is fixed in the pump body, and the other end of the check valve piece abuts against the outer diameter of one side of the eccentric wheel for check. The central axis of the eccentric wheel passes through the pump body and is connected to the driving wheel 6 in the gearbox. The driving wheel meshes with the first driven wheel 7 and the second driven wheel 8. At the same time, a cam 10 is provided at one end of the gear shaft of the second driven wheel, and one side of the cam abuts against the other end of the pry bar in the gearbox. At least three equally spaced blades 301 are provided on the outer diameter of the eccentric wheel. One side of the blade abuts against and seals the inner wall of the vent hole at one side of two adjacent quick connectors in the pump body through the eccentrically arranged central axis on the eccentric wheel. The check valve piece is arranged at the pump port at this side of the pump body. Check valve grooves 302 are respectively provided at the positions of the blades on the outer diameter of the eccentric wheel corresponding to the check valve piece. When the eccentric wheel rotates reversely, the check valve grooves abut against and are limited by the check valve piece. The air collecting film of the above air collecting mechanism is convex or concave.

[0024] According to the structure of the air collecting mechanism in the above Embodiment 1, as Figures 9 - 10 shown in Embodiment 2, the above actuating mechanism may be a cylinder actuated unlocking device. One end of the quick connector at one end of the air pipe is connected to one end of the cylinder plug 26. The other end of the cylinder plug is connected to the cylinder body 21. A second sealing ring 25 is provided at the connection of the cylinder plug. A spring 22 is provided on the outer diameter of the rod part at one end of the piston rod 23 in the cylinder body and extends out of the cylinder body. A first sealing ring 24 is provided at the end of the other end of the piston rod. The first sealing ring abuts against and seals the inner wall of the cylinder body. The two ends of the spring respectively abut against the exhaust hole at one end in the cylinder body and the end of the piston rod. The extended piston rod is the actuating part of the actuating mechanism.

[0025] According to the structural design of the above Embodiment 1 and Embodiment 2, the air collecting mechanism includes the above Scheme 1 and Scheme 2, and the actuating mechanism includes Scheme 1 and Scheme 2. The specific structures are as follows: Scheme 1 of the air collecting mechanism: a convex air collecting film. Air generates air pressure to impact the air collecting film. The air collecting film is compressed and sinks downward to collect air. Then, the air collecting film rebounds to the initial position through the compression spring. The formed pressure difference is balanced through the through holes of the air collecting film; through the repeated compression and rebound of the air collecting film, air pressure is collected to achieve the effect of collecting air pressure.

[0026] Scheme 2 of the air collecting mechanism: a concave air collecting film. Air generates air pressure to impact the air collecting film. The air collecting film vibrates up and down to collect air. The pressure difference formed during the process of vibrating and collecting gas is balanced through the through holes of the air collecting film; through the repeated vibration of the air collecting film, air pressure is collected to achieve the effect of collecting air pressure.

[0027] Scheme 1 of the actuator: The pry bar pushes the unlocking device, air pressure enters the pump body to drive the eccentric wheel to rotate. The eccentric wheel and the blade are integrally formed. The blade will open as the distance between the blade and the pump body increases, and will close as the distance between the eccentric wheel and the pump body decreases. The gas will be discharged to the outside of the energy storage cabinet through the exhaust pipe (this is the key to generating pressure difference). The check valve prevents the eccentric wheel from reversing. The gear assembly in the gearbox composed of the driving wheel, the first driven wheel and the second driven wheel increases the driving force. Thus, the gear assembly drives the cam, the cam pushes the pry bar, the pry bar unlocks the actuator, and the pry bar resets through the torsion spring.

[0028] Scheme 2 of the actuator: The cylinder pushes the unlocking device, air pressure enters the cylinder body to push the piston rod, and the piston rod unlocks the actuator and resets through the spring.

[0029] To sum up, the emergency unlocking device has the advantages of low cost, smooth unlocking, safety and reliability, etc., ensuring the safety of the energy storage cabinet in case of emergency, especially ensuring the safety in case of small spontaneous combustion and explosion inside the energy storage cabinet.
