Description

Technical Field

[0001] This invention relates to the field of energy storage combiner cabinet technology, and more specifically to an energy storage combiner cabinet locking device. Background Technology

[0002] As the high-voltage junction core hub connecting battery clusters and PCS (energy storage converter) in an energy storage system, the operational safety and stability of the energy storage combiner cabinet directly determine the reliable operation of the entire energy storage system. In practical applications, there are prominent safety risks such as high-voltage electric shock and misoperation. As a core component for achieving the "five protections" of power equipment (preventing accidental opening and closing of circuit breakers, preventing opening and closing of isolating switches under load, preventing the connection and closing of grounding wires while energized, preventing closing of switches with grounding wires, and preventing accidental entry into energized compartments), the interlocking device is crucial to ensuring the personal safety of operation and maintenance personnel and avoiding equipment failure. However, traditional interlocking devices have poor compatibility with the cabinet structure and system communication protocol of the energy storage combiner cabinet, and the installation process is cumbersome, making it difficult to adapt to the mainstream demand of the current energy storage system development towards integration, miniaturization, and intelligence. Therefore, there is an urgent need to develop a new type of energy storage combiner cabinet interlocking device that is highly adaptable, safe and reliable, and has intelligent linkage function to improve the operation and maintenance safety and user experience of the energy storage combiner cabinet. Meanwhile, during daily operation, the internal support structure of the energy storage combiner cabinet can obstruct the airflow inside the cabinet, resulting in poor airflow circulation for the heat dissipation of the motor components at the bottom of the cabinet. This significantly reduces the cooling effect of the motor components. If the motor components are in a state of insufficient cooling for a long time, they are prone to aging of internal circuits and deterioration of insulation performance due to excessive temperature, which can lead to short circuit failures. In severe cases, it may even cause major safety accidents such as fires and explosions, further threatening the overall safety of the energy storage system. In addition, the battery components inside the energy storage combiner cabinet are usually placed and installed using trays. In actual operation and maintenance, the motor components should be placed in the center of the tray as much as possible and kept in a standardized arrangement. This can improve the aesthetics of the internal structure of the energy storage combiner cabinet and make it easier for maintenance personnel to organize the circuits and repair the equipment. If the components are not placed in a standardized manner or are off-center, it will not only damage the regularity of the internal structure of the cabinet and reduce the overall aesthetics, but also lead to a messy wiring layout, increase the difficulty of subsequent circuit organization and equipment repair, and affect the standardization and efficiency of the operation and maintenance of the energy storage combiner cabinet. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an energy storage combiner cabinet interlocking device to solve the problems existing in the background art.

[0004] The present invention provides the following technical solution: an energy storage combiner cabinet interlocking device, comprising a combiner cabinet body, a cooler fixedly installed on the top of the combiner cabinet body, ventilation ducts on both side walls of the combiner cabinet body, a hub device installed inside the combiner cabinet body, a support plate assembly at the bottom of the hub device, a cabinet door on the outside of the hub device and the support plate assembly, a motor assembly supported on the top of the support plate assembly, and an air outlet at the bottom of the ventilation ducts, the position of the air outlet corresponding to the support plate assembly.

[0005] Furthermore, a rotating shaft is installed on the inner wall of the main body of the junction box. One end of the rotating shaft is fixedly connected to a rotating handle, and the other end of the rotating shaft is fixedly connected to a fixing plate.

[0006] Furthermore, a baffle plate is installed inside the air outlet, and gear shafts are installed at both ends of the baffle plate. The gear shafts mesh with a gear belt, and the other end of the gear belt meshes with a gear on the surface of a rotating shaft.

[0007] Furthermore, the tray assembly includes a lower tray and an upper tray. The lower tray is fixedly connected to the inner wall of the main body of the junction box. A spring self-locking device is fixedly connected inside the lower tray. The spring self-locking device is fixedly connected to the upper tray. A roller frame is fixedly connected to the bottom of the upper tray. The lower tray has a roller groove, and a roller frame is fitted inside the roller groove.

[0008] Furthermore, an anti-detachment pad is fixedly connected to the top of one end of the upper support plate, and a slot plate is fixedly connected to the top of the other end of the upper support plate. The groove on the top of the slot plate can be nested with the fixed slot plate.

[0009] Furthermore, a handle groove is provided on the main body of the junction box at the position corresponding to the rotation of the rotating handle, and a switch device is installed at the bottom of the handle groove.

[0010] Furthermore, a first spring is installed inside the lower support plate. One end of the first spring is fixed to the inner wall of the groove of the lower support plate, and the other end of the first spring is fixedly connected to the trapezoidal plate.

[0011] Furthermore, trapezoidal push plates are provided at both ends of the trapezoidal plate. A second spring and a sliding shaft push plate are installed on the side of the trapezoidal push plate near the inner wall of the main body of the junction box. The other end of the second spring is fixed to its inner wall, and the sliding shaft push plate is sleeved in the inner wall of the main body of the junction box.

[0012] Furthermore, the sliding shaft push plate has a sliding shaft hole, and a sliding shaft push rod is sleeved inside the sliding shaft hole. The other end of the sliding shaft push rod is fixedly connected to a push rod spring.

[0013] Furthermore, the sliding shaft push rod has a push rod groove inside, and an angled plate is slidably sleeved inside the push rod groove. A rubber push plate is fixedly connected to the outside of the angled plate, and a fourth spring is fixedly connected to both ends of the rubber push plate.

[0014] The technical effects and advantages of this invention are as follows: 1. This invention uses the ventilation duct wall to deliver the cold air generated by the air cooler from the air outlet of the corresponding level to the motor components placed at different heights, thereby achieving rapid cooling of each layer of the junction box trays, reducing the obstruction of airflow by the tray structure, and improving the cooling effect of the cooling airflow on the bottom motor components.

[0015] 2. The present invention can control the opening and closing of the baffle plate by rotating the rotating shaft. When the air outlet of this layer is not in use, it can be closed to increase the airflow. At the same time, the motor assembly and the card slot plate can be fixed by rotating the handle and fixing the card plate respectively.

[0016] 3. This invention uses a trapezoidal plate to push a trapezoidal push plate outward, which in turn uses the inclined groove of the sliding shaft hole to push the sliding shaft push rod to reciprocate. Then, the push rod slide groove pushes the rubber push plate to extend and retract. This structure uses the inward pushing force of the motor assembly to make the rubber push plates on both sides push the motor assembly inward to center, ensuring that the motor assembly is placed in a standardized manner. When the motor assembly is removed, the rubber push plate loses the pushing force of the sliding shaft push rod, and the fourth spring pulls the rubber push plate to reset, which facilitates the subsequent placement of the motor assembly.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The energy storage combiner cabinet involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figure 1-11This invention provides an energy storage combiner cabinet interlocking device, including a combiner cabinet body 1. A cooler 2 is fixedly installed on the top of the combiner cabinet body 1. Ventilation pipe walls 3 are provided on both side walls of the combiner cabinet body 1. A hub device 8 is installed inside the combiner cabinet body 1. A support plate assembly 6 is provided at the bottom of the hub device 8. A cabinet door 9 is provided outside the hub device 8 and the support plate assembly 6. A motor assembly 7 is supported on the top of the support plate assembly 6. An air outlet 5 is provided at the bottom of the ventilation pipe wall 3, and the position of the air outlet 5 corresponds to that of the support plate assembly 6. This structure generates a cool airflow through the cooler 2 installed on the top of the combiner cabinet body 1. The cool airflow is delivered to the corresponding air outlet 5 through the ventilation pipe wall 3, thereby cooling the motor assembly 7 on the top of the support plate assembly 6. This prevents the motor assembly 7 from short-circuiting due to heat accumulation when transmitting current or data to the hub device 8. At the same time, the cabinet door 9 on the outside of the combiner cabinet body 1 can prevent the cool airflow from dissipating quickly and ensure stable cooling effect.

[0031] In a preferred embodiment, a rotating shaft 101 is installed on the inner wall of the main body 1 of the combiner cabinet. A rotating handle 103 is fixedly connected to one end of the rotating shaft 101, and a fixing plate 106 is fixedly connected to the other end of the rotating shaft 101. A slot plate 302 is provided on the outside of the fixing plate 106. After the operator places the motor assembly 7, the rotating handle 103 is rotated to fit the surface of the motor assembly 7 to prevent the motor assembly 7 from falling off due to the tilt of the cabinet. At the same time, when the rotating handle 103 rotates, it will drive the fixing plate 106 to rotate synchronously through the rotating shaft 101, so that the fixing plate 106 is embedded in the groove of the slot plate 302, thereby fixing the tray assembly 6 and preventing it from sliding or shifting.

[0032] In a preferred embodiment, a baffle plate 105 is installed inside the air outlet 5. Gear shafts 104 are installed at both ends of the baffle plate 105. The gear shafts 104 mesh with a gear belt 102, and the other end of the gear belt 102 meshes with a gear on the surface of the rotating shaft 101. When the rotating shaft 101 rotates, the gear shaft 104 is driven to rotate synchronously through the meshing of the gear on its surface with the gear belt 102. This causes the baffle plate 105 to switch from a vertical state inside the air outlet 5 to a horizontal state, thereby facilitating the smooth entry of the cold airflow flowing inside the ventilation duct wall 3 into the interior of the tray layer. This achieves rapid cooling of each tray layer of the junction box, reduces the obstruction of the airflow by the tray structure, and improves the cooling effect of the cooling airflow on the bottom motor assembly 7.

[0033] In a preferred embodiment, the pallet assembly 6 includes a lower pallet 201 and an upper pallet 203. The lower pallet 201 is fixedly connected to the inner wall of the main body 1 of the junction box. A spring self-locking device 202 is fixedly connected inside the lower pallet 201. The top end of the spring self-locking device 202 is fixedly connected to the upper pallet 203. A roller frame 204 is fixedly connected to the bottom of the upper pallet 203. A roller groove 205 is provided on the lower pallet 201, and the roller frame 204 is fitted inside the roller groove 205. This structure, through the extension and retraction movement of the spring self-locking device 202, pushes the upper pallet 203 to extend outward from the main body 1 of the junction box, making it convenient for the operator to move the motor assembly 7 and avoiding inconvenience caused by the narrow storage opening. At the same time, the roller frame 204 at the bottom of the upper pallet 203 can slide synchronously inside the roller groove 205 as the upper pallet 203 moves, effectively improving the smoothness of the movement of the upper pallet 203 and reducing the difficulty of operation.

[0034] In a preferred embodiment, an anti-detachment pad 301 is fixedly connected to the top of one end of the upper support plate 203, and a slot plate 302 is fixedly connected to the top of the other end of the upper support plate 203. The groove on the top of the slot plate 302 can nest with the fixed slot plate 106. This structure improves the anti-detachment effect of the motor assembly 7 after placement by using the anti-detachment pad 301 on the surface of the upper support plate 203, and avoids the motor assembly 7 from sliding and shifting. At the same time, by using the nesting cooperation between the groove on the top of the slot plate 302 and the fixed slot plate 106, the lower support plate 201 and the upper support plate 203 can be stably fixed when they are closed, ensuring the closing stability of the support plate assembly 6.

[0035] In a preferred embodiment, a handle groove 401 is provided on the main body 1 of the junction box at a position corresponding to the rotation trajectory of the rotating handle 103. A switch device 402 is installed at the bottom of the handle groove 401. When the operator needs to place the motor assembly 7, he / she rotates the rotating handle 103 into the handle groove 401, and the rotating handle 103 presses down on the switch device 402 at the bottom of the handle groove 401. The switch device 402 is electrically connected to the spring self-locking device 202 through a circuit board. After the switch device 402 is triggered, the spring self-locking device 202 automatically extends, pushing the upper support plate 203 to extend outward, so that the operator can place the motor assembly 7 smoothly.

[0036] In a preferred embodiment, a first spring 501 is installed inside the lower support plate 201. One end of the first spring 501 is fixedly connected to the inner wall of the groove of the lower support plate 201, and the other end of the first spring 501 is fixedly connected to a trapezoidal plate 503. Trapezoidal push plates 601 are provided on both sides of the trapezoidal plate 503. After the operator places the motor assembly 7, he pushes the motor assembly 7 into the main body 1 of the junction box. The metal shell at the bottom of the motor assembly 7 will squeeze the trapezoidal plate 503, causing the trapezoidal push plates 601 on both sides of the trapezoidal plate 503 to move to both sides. Since the weight of the motor assembly 7 is greater than the elastic force of the first spring 501, it can prevent the trapezoidal plate 503 from rebounding on its own. When the motor assembly 7 is stretched outward, the squeezing force on the trapezoidal plate 503 disappears, the first spring 501 resets and pushes the trapezoidal plate 503 back to its initial position.

[0037] In a preferred embodiment, a second spring 602 and a sliding shaft push plate 603 are respectively installed on the side of the trapezoidal push plate 601 near the inner wall of the main body 1 of the junction box. The other end of the second spring 602 is fixedly connected to the inner wall of the main body 1 of the junction box, and the sliding shaft push plate 603 is movably sleeved in the inner wall of the main body 1 of the junction box. When the trapezoidal push plate 601 is pushed by the trapezoidal plate 503, it drives the sliding shaft push plate 603 to move away from the center of the junction box, while compressing the second spring 602 to store energy. When the trapezoidal plate 503 is reset and the pushing force on the trapezoidal push plate 601 disappears, the second spring 602 releases its elastic force, pushing the trapezoidal push plate 601 and the sliding shaft push plate 603 to reset synchronously.

[0038] In a preferred embodiment, the sliding shaft push plate 603 has a sliding shaft hole 604, and a sliding shaft push rod 605 is sleeved inside the sliding shaft hole 604. The other end of the sliding shaft push rod 605 is fixedly connected to a push rod spring 606, and the other end of the push rod spring 606 is fixedly connected to the inner wall of the main body 1 of the junction box. When the sliding shaft push plate 603 of this structure performs telescopic movement, the sliding shaft push rod 605 is driven to reciprocate synchronously through the sliding shaft hole 604 on its surface. The push rod spring 606 can assist the sliding shaft push rod 605 to return to its original position, ensuring the smoothness of the transmission process.

[0039] In a preferred embodiment, the sliding shaft push rod 605 has a push rod groove 701 inside, and an angled plate 702 is slidably sleeved inside the push rod groove 701. A rubber push plate 703 is fixedly connected to the outside of the angled plate 702. A fourth spring 704 is fixedly connected to both ends of the rubber push plate 703, and the other end of the fourth spring 704 is fixedly connected to the inner wall of the junction box body 1. When the sliding shaft push rod 605 reciprocates, it pushes the angled plate 702 sleeved inside the push rod groove 701. 2. The internal rubber push plate 703 extends towards the center of the junction box. The force generated by the inward squeezing of the trapezoidal plate 503 is transmitted through the trapezoidal push plate 601 and the sliding shaft push rod 605, and is converted into the pushing force of the rubber push plate 703 moving towards the center, thereby pushing the placed motor assembly 7 to the center position, ensuring that the motor assembly 7 is placed in a standardized manner. When the motor assembly 7 is removed, the rubber push plate 703 loses the pushing force of the sliding shaft push rod 605, and the fourth spring 704 pulls the rubber push plate 703 to reset, which facilitates the subsequent placement of the motor assembly 7.

[0040] The working principle of this invention is as follows: A cooler 2 fixedly installed at the top of the main body 1 of the combiner cabinet generates a cool airflow. The cool airflow is transported through ventilation pipes 3 opened on both sides of the combiner cabinet. Air outlets 5 are opened at the bottom of the ventilation pipes 3 corresponding to the positions of each layer of support plate assemblies 6. The cool airflow is accurately transported through the air outlets 5 to the motor assembly 7 supported at the top of each layer of support plate assemblies 6, thereby achieving rapid cooling of each layer of support plates in the combiner cabinet, effectively reducing the obstruction of airflow by the support plate structure, and significantly improving the cooling effect of the cooling airflow on the bottom motor assembly 7. At the same time, the cabinet door 9 set on the outside of the main body 1 of the combiner cabinet can reduce the loss of cool airflow and ensure the stability of cooling. In addition, the baffle 105 installed inside the air outlet 5 can be opened and closed by rotating the rotating shaft 101. The gear on the surface of the rotating shaft 101 meshes with the gear belt 102, and the other end of the gear belt 102 meshes with the gear shafts 104 at both ends of the baffle 105. When the rotating shaft 101 rotates, it drives the gear belt 102 to drive the gear shaft 104 to rotate, thereby opening and closing the baffle 105 and preventing the unused air outlet 5 from being opened and affecting the airflow.

[0041] The locking and fixing structure of the device: A rotating shaft 101 installed on the inner wall of the main body 1 of the combiner cabinet is fixedly connected to a rotating handle 103 at one end and a fixing plate 106 at the other end. The top of the slot plate 302, which is fixedly connected to the other end of the upper support plate 203, has a groove on its top that matches the fixing plate 106. After the operator places the motor assembly 7, rotating the rotating handle 103 will drive the rotating shaft 101 to rotate, so that the rotating handle 103 fits against the surface of the motor assembly 7 to fix the motor assembly 7 and prevent it from falling off due to the tilt of the combiner cabinet. At the same time, the rotating shaft 101 drives the fixing plate 106 to rotate, so that the fixing plate 106 is nested into the groove of the slot plate 302 to fix the support plate assembly 6 and prevent it from sliding or shifting. In addition, a handle groove 401 is provided on the main body 1 of the combiner cabinet at a position corresponding to the rotation trajectory of the rotating handle 103. A switch device 402 is installed at the bottom of the handle groove 401. When it is necessary to place the motor assembly 7, the rotating handle 103 is rotated into the handle groove 401. Pressing down the switch device 402 can trigger the spring self-locking device 202 in the tray assembly 6 that is electrically connected to the switch device 402. The spring self-locking device 202 extends and pushes the upper tray 203 outward. The roller frame 204 at the bottom of the upper tray 203 slides in the roller groove 205 opened in the lower tray 201, improving the smoothness of the movement of the upper tray 203 and making it easier for the operator to move the motor assembly 7. Conversely, after pushing the upper tray 203 to close, the rotating handle 103 can be rotated to complete the fixation.

[0042] The centering structure of the motor assembly: One end of the first spring 501 installed inside the lower support plate 201 is fixed to the inner wall of the groove of the lower support plate 201, and the other end is fixedly connected to the trapezoidal plate 503. The trapezoidal plate 503 has trapezoidal push plates 601 at both ends. The trapezoidal push plate 601 is equipped with a second spring 602 and a sliding shaft push plate 603 on the side of the trapezoidal push plate 601 near the inner wall of the main body 1. A sliding shaft push rod 605 is sleeved in the sliding shaft hole 604 opened on the sliding shaft push plate 603. The other end of the sliding shaft push rod 605 is fixedly connected to the push rod spring 606. An angled plate 702 is slidably sleeved in the push rod groove 701 opened inside the sliding shaft push rod 605. A rubber push plate 703 is fixedly connected to the outside of the angled plate 702. A fourth spring 704 is fixedly connected to both ends of the rubber push plate 703. When the operator pushes the motor assembly 7 into the junction box, the bottom of the motor assembly 7 presses against the trapezoidal plate 503. The trapezoidal plate 503 pushes the trapezoidal push plates 601 on both sides towards the inner wall of the junction box. The trapezoidal push plates 601 drive the sliding shaft push plate 603 to move synchronously and compress the second spring 602 to store energy. When the sliding shaft push plate 603 moves, it pushes the sliding shaft push rod 605 to reciprocate through the sliding shaft hole 604. The sliding shaft push rod 605 pushes the angled plate 702 through the push rod groove 701, which in turn drives the rubber push plate 703 towards the inner wall of the junction box. Extending from the center, the rubber push plates 703 on both sides work together to push the motor assembly 7 to achieve center positioning, ensuring that the motor assembly 7 is placed in a standardized manner. When the motor assembly 7 is removed, the squeezing pressure on the trapezoidal plate 503 disappears, the first spring 501 resets and pushes the trapezoidal plate 503 back to its initial position, the second spring 602 releases its elastic force and pushes the trapezoidal push plate 601 and the sliding shaft push plate 603 to reset. After the sliding shaft push rod 605 loses its pushing force, the fourth spring 704 pulls the rubber push plate 703 to reset, which facilitates the subsequent placement of the motor assembly 7.
