Description

Technical Field

[0001] This invention relates to the field of capacitor technology, specifically to an electrochemical capacitor. Background Technology

[0002] An electrochemical capacitor has a pair of electrodes and an electrolyte. At least one of the electrodes contains an active material that can adsorb and desorb ions. As an example of an electrochemical capacitor, the electric double-layer capacitor has a longer lifespan than a secondary battery, can be charged quickly, has excellent output characteristics, and is widely used in backup power supplies.

[0003] In existing technologies, such as the "Large Capacity High Energy Density Electrochemical Capacitor" with Chinese Patent No. CN215868994U, a plastic shell is included. Adhesive layers are bonded to the inner two surfaces of the plastic shell. A discharge unit is adhered to one side of the adhesive layer. Each discharge unit includes an anode, a composite separator, and a cathode. The composite separator is located between the anode and cathode. The anodes in each discharge unit are connected by internal wiring, which is connected to an anode lead. One end of the anode lead is connected to the internal wiring, and the other end extends out of the plastic shell. The plastic shell is filled with electrolyte. The cathodes in the discharge units are connected by the electrolyte and ultimately led out by cathode leads. Each discharge unit is connected in parallel through internal wiring, forming a combination of supercapacitor elements, thus more effectively utilizing the large capacity and high energy density of the formed supercapacitor.

[0004] However, while existing technologies have achieved the combination of supercapacitor elements, which can more effectively utilize the large capacity and high energy density of the supercapacitor, the capacitor elements will age and short-circuit after prolonged use, causing explosions. This makes explosion-proof protection inconvenient and affects the safety of use. Therefore, there is an urgent need for an electrochemical capacitor. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This electrochemical capacitor features an alloy shell and a sealing alloy steel plate made of alloy materials, possessing excellent toughness and strength, which enhances its impact resistance. The protective alloy steel shell uses a limiting semi-circular ring to restrict the capacitor body, while the movable locking hole facilitates the restriction of the cathode and anode leads of the capacitor body. The sealing alloy steel plate is connected to the connecting slot via a connecting plate, forming a complete shell. A high-strength alloy steel sleeve is fitted over the protective alloy steel shell and the sealing alloy steel plate. The high-strength alloy material further improves the impact resistance. The movable locking hole, combined with the heat dissipation holes, facilitates ventilation inside the shell, and the cooling fan helps to accelerate the airflow, facilitating air cooling of the capacitor body.

[0021] 2. This electrochemical capacitor has a smoke sensor inside its protective alloy steel shell. When the capacitor body catches fire, it cannot continue to dissipate heat. An electric cylinder pushes a smoke-proof baffle to block the heat dissipation holes, preventing smoke from spreading and debris from flying. The connecting ribs facilitate the connection between the first and second explosion-proof reinforcing ribs, further improving the overall explosion-proof performance. The layered protection helps reduce the impact of the explosion. The titanium alloy shell is lightweight, high-strength, and corrosion-resistant, providing external protection. The honeycomb airbags are placed between the titanium alloy shells to buffer and absorb the shock wave of the explosion.

[0022] 3. The electrochemical capacitor has a first vent and a second vent to facilitate heat dissipation and ventilation. The servo motor drives the transmission gear to rotate, and the transmission gear drives the transmission rack to move linearly, which facilitates the sealing of the first and second vents by the protective cover, further preventing debris from flying. The protective cover is initially limited by the connection between the moving block and the moving slide, and the anti-detachment slot and the anti-detachment block provide secondary limitation to prevent the protective cover from falling off due to the impact of the explosion. It can also seal the outlet to further prevent smoke from spreading. Attached Figure Description

[0040] Specifically, the capacitor body 1 can improve the overall explosion-proof effect through the first explosion-proof mechanism 2 and the second explosion-proof mechanism 3.

The protective shield 307 is conveniently used to seal the first ventilation opening 220 and the second ventilation opening 305, which further prevents debris from flying. The protective shield 307 is initially limited by the connection between the movable locking block 313 and the movable sliding groove 312.

[0043] Working Principle: First, the capacitor body 1 improves the overall explosion-proof effect through the first explosion-proof mechanism 2 and the second explosion-proof mechanism 3. The protective alloy steel shell 201 and the sealing alloy steel plate 204 are made of alloy material, which has good toughness and strength, and can improve the impact resistance. The protective alloy steel shell 201 limits the capacitor body 1 through the limiting semi-circular ring 202. The movable card hole 203 facilitates the limiting of the cathode and anode leads of the capacitor body 1. The sealing alloy steel plate 204 is connected to the connecting slot 206 through the connecting plate 205. The first support plate 207 provides support for the bottom of the sealing alloy steel plate 204, which facilitates the fixing of the sealing alloy steel plate 204 and the protective alloy steel shell 201, forming a complete shell. The high-strength alloy steel sleeve 213 is sleeved on the outside of the protective alloy steel shell 201 and the sealing alloy steel plate 204. The limiting slot 214 is engaged with the second support plate 215, which facilitates the engagement of the protective alloy steel shell. 201 is further fixed to the sealing alloy steel plate 204. The high-strength alloy material further improves the impact resistance. The movable card hole 203 cooperates with the heat dissipation hole 208 to facilitate ventilation inside the shell. The heat dissipation fan 209 helps to accelerate the air flow rate and facilitates air cooling of the capacitor body 1. The protective alloy steel shell 201 is equipped with a smoke sensor. When the capacitor body 1 catches fire, it cannot continue to dissipate heat. The smoke baffle 210 is pushed by the electric cylinder 212 to block the heat dissipation hole, preventing smoke from spreading and explosion debris from flying. The first explosion-proof reinforcing rib 216 is evenly sleeved longitudinally on the outside of the high-strength alloy steel shell 213. The second explosion-proof reinforcing rib 217 is evenly sleeved laterally on the outside of the first explosion-proof reinforcing rib 216. The connecting rib 218 facilitates the connection between the first explosion-proof reinforcing rib 216 and the second explosion-proof reinforcing rib 217, which further improves the overall explosion-proof performance. The layered protection helps to reduce the impact of the explosion.

[0044] The titanium alloy shell 301 is lightweight, high-strength, and corrosion-resistant, facilitating external protection. Honeycomb airbags 303 are positioned between the titanium alloy shells 301 to buffer and absorb the shockwave of an explosion. The top alloy steel plate 304 provides explosion protection for the top. The first ventilation opening 220 and the second ventilation opening 305 facilitate heat dissipation and ventilation. The fixing bracket 311 secures the servo motor 310, which drives the transmission gear 309 to rotate. The transmission gear 309 then drives the transmission rack 308 to move linearly. This causes the protective shield 307 to close the first ventilation opening 220 and the second ventilation opening 305, further preventing debris from flying. The protective shield 307 is initially limited by the connection between the movable locking block 313 and the movable sliding groove 312. The anti-detachment locking groove 314 and the anti-detachment locking block 315 provide secondary limitation to prevent the protective shield 307 from being detached due to the explosion impact. It can also close the outlet to further prevent smoke from spreading. The limiting round hole 219 and the fixing round hole 306 make it easy to expose the electrode connector of the capacitor body 1 for easy installation and connection.
