The silicon rectification is responsible for completing the power conversion from alternating current to direct current, the super capacitor bears the energy storage, and the protection circuit automatically cuts off the charging and discharging circuit when the capacitor voltage exceeds the safe range, so as to protect the safety of the device and the capacitor. However, in the use of the prior silicon rectification super capacitor DC power supply device capable of preventing overcharging and overdischarging, the super capacitor module is mostly integrated and fixedly installed, and many fixed structures need to be disassembled during disassembly.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-7 This invention provides a technical solution: a silicon rectifier supercapacitor DC power supply device with overcharge and over-discharge protection, comprising a cabinet 1. A protective door 2 is rotatably connected to one side surface of the placement cabinet 1. A stabilizing mechanism 3 is provided inside the placement cabinet 1. A heat dissipation mechanism 4 is provided inside the placement cabinet 1. A fire extinguishing mechanism 5 is provided inside the placement cabinet 1. A buffer mechanism 6 is provided inside the placement cabinet 1. The stabilizing mechanism 3 includes a support frame 301, a controller 302 connected above the support frame 301, a transformer 303 connected above the support frame 301, a fixing block 304 welded above the support frame 301, a placement groove 305 formed on one side of the fixing block 304, a locking block 306 provided inside the placement groove 305, a first spring 307 welded to one side of the locking block 306, a pull rod 308 welded to one side of the locking block 306, and a supercapacitor module 309 provided on one side of the fixing block 304. The 9 has slots 310 on both sides. The first spring 307 provides elastic driving force for the card block 306. After the pull rod 308 is released, the card block 306 can be automatically pushed into the slot 310 of the supercapacitor module 309 to complete the quick fixation of the module. The continuous elastic force of the first spring 307 can ensure that the card block 306 and the slot 310 fit tightly, preventing the supercapacitor module 309 from loosening or shifting due to the vibration of the placement cabinet 1, ensuring the stable operation of the electrical equipment, and facilitating the disassembly and replacement of the supercapacitor module 309.

[0023] Furthermore, a support frame 301 is provided on the inner side of the placement cabinet 1, and two sets of clamping blocks 306 are symmetrically welded on both sides of the supercapacitor module 309. Through the setting of the support frame 301, it serves as the installation carrier for core electrical components such as the supercapacitor module 309, controller 302, and transformer 303, providing a stable support platform for these components. This makes the internal layout of the placement cabinet 1 neat and orderly, and its rigid structure can withstand the weight load of the electrical components. At the same time, it provides a connection base for the buffer mechanism 6, transmitting the vibration of the components during operation to the buffer mechanism 6, achieving shock absorption and protection, and extending the service life of the electrical components.

[0024] Furthermore, the pull rod 308 connects to the locking block 306, which compresses the first spring 307 to form a telescopic structure. The pull rod 308 passes through the fixing block 304 and connects to the locking block 306. Through the setting of the pull rod 308, it serves as the control component of the stabilizing mechanism 3. When pulled, it can drive the locking block 306 to compress the first spring 307 and enter the placement slot 305, thereby releasing the lock on the supercapacitor module 309 and facilitating the disassembly and maintenance of the module. The design of the pull rod 308 passing through the fixing block 304 can precisely control the movement direction of the locking block 306, avoiding the locking block 306 from shifting and causing the lock to fail. The operation is simple and requires no additional tools, improving the convenience of disassembly and assembly of the supercapacitor module 309.

[0025] Furthermore, the heat dissipation mechanism 4 includes a support frame 401, a first drive motor 402 connected to the top of the support frame 401, a coupling 403 connected to the output end of the first drive motor 402, a connecting rod 404 connected to the inner side of the coupling 403, a main drive gear 405 sleeved on the outer side of the connecting rod 404, a driven gear 407 meshing with the outer side of the main drive gear 405, a reciprocating screw 408 connected to the inner side of the driven gear 407, a sliding frame 409 threadedly connected to the outer side of the reciprocating screw 408, and a second drive motor 412 connected to the inner side of the sliding frame 409. The output end of 12 is connected to a synchronizing rod 413. A fan blade 415 is sleeved on the outside of the synchronizing rod 413. Through the setting of the main transmission gear 405, it rotates synchronously with the connecting rod 404. Through the meshing with the driven transmission gears 407 on both sides, the single power source of the first drive motor 402 is converted into the rotational power of two sets of reciprocating lead screws 408, realizing the synchronous reciprocating lifting of the two sets of sliding frames 409. The meshing transmission ratio of the main transmission gear 405 and the driven transmission gear 407 is stable, which can ensure that the movement trajectory of the two sets of sliding frames 409 is consistent, so that the fan blade 415 can evenly dissipate heat to the inside of the placement cabinet 1 and avoid local heat dissipation blind spots.

[0026] Furthermore, a support frame 301 is welded to the top of the placement cabinet 1. Limiting blocks 411 are sleeved on both ends of the reciprocating screw 408. The limiting blocks 411 are welded to the inner wall of the placement cabinet 1. Through the setting of the reciprocating screw 408, it rotates under the drive of the transmission gear 407, converting its own rotational motion into the linear reciprocating motion of the sliding frame 409, thereby driving the fan blade 415 to move up and down inside the placement cabinet 1. The structure of the reciprocating screw 408 can automatically control the movement direction of the sliding frame 409 without the need for an additional reversing device. With the help of the limiting blocks 411, the stroke of the sliding frame 409 can be precisely controlled to ensure that the heat dissipation range covers the entire area of ​​the placement cabinet 1.

[0027] Furthermore, an auxiliary light rod 410 is slidably connected to the other side of the sliding frame 409. Limiting blocks 411 are also fitted at both ends of the auxiliary light rod 410. A protective net 414 is welded to one side of the sliding frame 409. The first drive motor 402 and the second drive motor 412 are electrically connected to the second drive motor 412 respectively. Through the setting of the second drive motor 412, the synchronous rod 413 and the fan blade 415 are driven to rotate at high speed, generating a continuous airflow. The heat generated by the operation of the electrical components inside the cabinet 1 is discharged through the heat dissipation hole 506. At the same time, the linkage with the first drive motor 402 realizes the composite heat dissipation of rotational blowing and reciprocating movement, thereby improving the heat dissipation efficiency.

[0028] Furthermore, the fire extinguishing mechanism 5 includes a placement frame 501, with a fire extinguisher 502 installed inside the placement frame 501. A connecting pipe 503 is connected above the fire extinguisher 502, and a solenoid valve 504 is sleeved on the outside of the connecting pipe 503. One end of the connecting pipe 503 is connected to a nozzle 505. Heat dissipation holes 506 are opened on both sides of the placement cabinet 1, and a smoke detector 507 is connected to one side of the heat dissipation hole 506. Through the setting of the smoke detector 507, the air quality inside the placement cabinet 1 is monitored in real time. When smoke or fire precursors are detected, the signal can be quickly transmitted to the controller 302. The linkage design between the smoke detector and the controller 302 can realize the automation of fire extinguishing operation without manual intervention. It can start the fire extinguishing program in time in the early stage of fire, reducing the risk of fire damage to electrical components.

[0029] Furthermore, a placement frame 501 is welded to one side of the placement cabinet 1, and a connecting pipe 503 passes through the placement cabinet 1 and connects to the nozzle 505. The smoke detector 507 is electrically connected to the controller 302. Through the setting of the nozzle 505, the dry powder in the fire extinguisher 502 is evenly sprayed into the interior of the placement cabinet 1, covering the fire area and achieving rapid fire extinguishing. The distribution position of the nozzle 505 is adapted to the internal layout of the placement cabinet 1, which can ensure that the dry powder covers all electrical components. At the same time, its atomized spray design can increase the contact area between the dry powder and the flame, and enhance the fire extinguishing effect.

[0030] Furthermore, the buffer mechanism 6 includes a connecting piece 601, a second spring 602 welded to the lower end of the connecting piece 601, a pressure rod 603 welded to the lower end of the connecting piece 601, a pressure plate 604 welded to one end of the pressure rod 603, a sleeve 605 sleeved on the outer side of the pressure plate 604, and a flow tube 606 connected through one side of the sleeve 605. Through the setting of the pressure rod 603, it serves as a power transmission component of the buffer mechanism 6. As the connecting piece 601 bears the vibration pressure of the support frame 301, it drives the pressure plate 604 to squeeze the damping fluid in the sleeve 605. Through the flow of the damping fluid in the flow tube 606, the vibration energy is converted into the kinetic energy of the liquid, achieving initial damping. At the same time, the movement of the pressure rod 603 can compress the second spring 602, and the elastic deformation of the second spring 602 further absorbs the vibration energy. The double damping protects the electrical components from vibration damage.

[0031] Furthermore, a connecting piece 601 is welded to one side surface of the support frame 301, and the other end of the first spring 307 is connected to the inner wall of the placement cabinet 1. The pressure rod 603 is connected to the connecting piece 601 through the sleeve 605, and the flow tube 606 is connected through the two sets of sleeves 605. The flow tube 606 connects the two sets of sleeves 605 to provide a flow channel for the damping fluid. When the pressure plate 604 squeezes the damping fluid, the damping fluid circulates between the two sets of sleeves 605. The viscous resistance of the liquid is used to consume vibration energy and achieve buffering and damping. The interconnected design of the flow tube 606 allows the damping action of the two sets of sleeves 605 to be synchronized, balancing the force on the support frame 301 and avoiding excessive local vibration that could cause component displacement.

[0032] Working principle: First, the operator opens the protective door 2, then pulls the lever 308. The lever 308 then moves the locking block 306 into the placement slot 305. Upon entering the placement slot 305, it compresses and stores the first spring 307. Next, the corresponding supercapacitor module 309 is placed onto the support frame 301, ensuring the locking slot 310 aligns with the placement slot 305. Then, the operator releases the lever 308, and with the help of the first spring 307, a portion of the locking block 306 is pushed into the locking slot 310. This completes the installation and fixation of the supercapacitor module 309. Then, during the use of the entire device... The second drive motor 412 is started, and then the second drive motor 412 drives the fan blade 415 to rotate through the synchronous rod 413. Then the heat inside the device can be discharged through the heat dissipation hole 506. Next, the first drive motor 402 is started, and then the first drive motor 402 drives the connecting rod 404 to rotate through the coupling 403. When the connecting rod 404 rotates, it drives the main transmission gear 405 to drive the driven transmission gears 407 on both sides to drive the two sets of reciprocating screws 408 to rotate synchronously. Then, the reciprocating screws 408 drive the two sets of sliding frames 409 to drive the internal components to reciprocate and lift, thereby placing the cabinet 1 inside. Uniform air cooling provides heat dissipation. During the lifting and lowering of the sliding frame 409, it is guided by the auxiliary guide rod 410. Vibrations generated during heat dissipation by the heat dissipation mechanism 4 are transmitted to the placement cabinet 1 and the support frame 301. When the vibration causes the support frame 301 to press down via the connecting plate 601, the connecting plate 601 transmits the vibration to the pressure rod 603. The pressure rod 603 then drives the pressure plate 604 to compress the damping fluid within the sleeve 605. The damping fluid is then transmitted through the flow pipe 606 to compress the damping fluid within another sleeve 605, achieving a cushioning and shock absorption effect. Simultaneously, it also compresses the second spring 602. Then, the elasticity of the second spring 602 is used to further enhance the buffering effect. Then, when the air flows through the heat dissipation hole 506, the smoke detector 507 will always monitor the air quality. When the smoke fire is detected in the temporal part of the cabinet 1, the signal is transmitted to the controller 302. Then the controller 302 shuts off the brakes of the first drive motor 402 and the second drive motor 412, and then controls the solenoid valve 504 to open, so that the fire extinguishing dry powder can be sprayed out from the fire extinguisher 502, then flows through the connecting pipe 503, and finally sprays out from the nozzle 505 to perform a timely fire extinguishing operation in the cabinet 1.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
