Description

Technical Field

[0001] The present invention relates to the technical field of combiner cabinets, and in particular to a drawer mechanism of a combiner cabinet and the combiner cabinet. Background Art

[0002] A combiner cabinet is a device used to concentrate and distribute electrical energy in a power system. Its function is to collect the electrical energy of multiple battery packs or other power sources and distribute it to loads or other equipment. Combiner cabinets are widely used. They are not only used to control and distribute current in substations and distribution rooms to ensure the normal operation of the power system, but are also widely used in power systems in industrial production, commercial buildings and large public facilities to control the current distribution between different devices.

[0003] The combiner cabinet in the energy storage system is an important component that connects the battery pack and the inverter. It can aggregate the DC power of multiple battery modules and then transmit it to the inverter to achieve DC to AC conversion. In the entire energy storage system, the combiner cabinet only accounts for a part of the whole. Its essence is an integrated power electronic component module in the energy storage system.

[0004] When the combiner cabinet is installed in the energy storage system, it is usually installed on the energy storage system cabinet in an embedded form. This means that the combiner cabinet can only be opened from the front door of the cabinet when it needs to be opened later. This is extremely inconvenient, especially when inspecting and maintaining the combiner cabinet. First, the cabinet door is narrow and difficult to observe, and there are many electronic components integrated inside the cabinet, which makes it impossible for staff to enter the combiner cabinet for operation. The side of the cabinet cannot be opened because it is embedded in the energy storage system cabinet. As a result, the inspection and maintenance of the combiner cabinet usually requires the combiner cabinet to be disassembled as a whole, which is very time-consuming and labor-intensive. Therefore, when manufacturing the combiner cabinet and the electronic components inside it, it is necessary to consider the subsequent inspection and maintenance issues. Summary of the invention

[0038] A pressing assembly is provided in the limiting hole 206, and a driving assembly is provided at one end of the pressing assembly. An unlocking assembly and a power-off assembly are provided on the driving assembly. The unlocking assembly and the power-off assembly are both arranged inside the busbar 200. The unlocking assembly is slidably matched with the upper track 204. When the pressing assembly is pressed, the driving assembly is pushed to move, so as to drive the unlocking assembly to release the lock between the busbar 200 and the upper track 204, and at the same time drive the power-off assembly to disconnect the power to the busbar 200.

[0039] The present invention locks the busbar 200 by providing an unlocking component to prevent it from sliding back and forth during transportation or maintenance. When the staff inspects and maintains the busbar cabinet, they press the pressing component and then push the driving component to move, so as to drive the unlocking component to release the lock between the busbar 200 and the upper track 204, and at the same time drive the power-off component to disconnect the power to the busbar 200, so that the busbar 200 can be easily pulled out after the power is cut off, and the electronic components on the busbar 200 can be inspected and maintained.

[0041] Specifically, when the pressing block 400 is no longer pressed by the staff, the reset spring 402 helps the pressing assembly to quickly reset and re-lock the busbar 200, so that the busbar 200 can be stopped from being pulled out and locked at any time, so that the staff does not need to pull out the busbar 200 completely for inspection and maintenance, and the busbar 200 can remain stable during inspection and maintenance without sliding back and forth to affect the inspection and maintenance.

[0042] In an embodiment further provided by the present invention, the driving assembly includes a driving plate 405 fixedly connected to one end of a driving rod 404, and a plurality of sliding blocks 407 are fixedly connected to both side surfaces of the driving plate 405, and the plurality of sliding blocks 407 are respectively slidably matched with the inner side surfaces of the busbar 200, and a driving groove 408 is provided at one end of the driving plate 405, and a driving tube 406 is fixedly connected in the driving groove 408.

[0043] In an embodiment further provided by the present invention, a first slot 202 is provided on the upper surface of the busbar 200, and the unlocking assembly includes a locking plate 505 slidably connected in the first slot 202, and a locking rod 504 is fixedly connected to the lower surface of the locking plate 505, and the lower end of the locking rod 504 is connected to the unlocking rod 502, and the lower end of the unlocking rod 502 passes through the inner lower surface of the first slot 202, and a return spring 503 is connected between the locking rod 504 and the inner lower surface of the first slot 202, and the return spring 503 is arranged outside the locking rod 504.

[0044] Specifically, the locking rod 504 is wider than the unlocking rod 502. When locked, one end of the recovery spring 503 contacts the upper lower surface of the first slot 202. When unlocked, the locking rod 504 descends and compresses the recovery spring 503. When locked again, the recovery spring 503 helps the unlocking assembly to quickly reset and lock again.

[0045] In an embodiment further provided by the present invention, the unlocking assembly also includes an unlocking plate 500 arranged inside the driving groove 408, and the upper surface of the unlocking plate 500 is fixedly connected to the lower end of the unlocking rod 502, and an unlocking groove 501 is provided on one side surface of the unlocking plate 500, and the driving tube 406 slides in cooperation with the unlocking groove 501.

[0046] Specifically, the unlocking slot 501 is an inclined slot structure. When the driving plate 405 moves forward, it drives the driving tube 406 to slide on the unlocking slot 501 , so that the unlocking plate 500 moves downward along the direction of the unlocking slot 501 .

[0047] In an embodiment further provided by the present invention, the lower surface of the upper rail 204 is a rack-shaped groove structure, and the upper surface of the locking plate 505 is another rack-shaped groove structure corresponding to the upper rail 204, and when the locking plate 505 is engaged with the upper rail 204, the busbar 200 is locked, and when the locking rod 504 pulls the locking plate 505 down, the upper rail 204 and the locking plate 505 are disengaged to release the lock on the busbar 200.

[0048] In an embodiment further provided by the present invention, the power-off assembly includes a connecting rod 600 fixedly connected to one end of the driving plate 405, and one end of the connecting rod 600 is abutted against a transmission rod 601, and an outer tube 602 is sleeved on the outside of the transmission rod 601, and a fixed block 604 is fixedly connected to the surface of the outer tube 602, and the fixed block 604 is fixedly connected to the surface of one side of the inner side of the busbar 200, and a transmission tube 605 is fixedly connected to the surface of the transmission rod 601, and a transmission groove 603 is provided on the surface of the outer tube 602, and the transmission tube 605 slides in cooperation with the transmission groove 603.

[0049] Specifically, the transmission groove 603 is a spiral groove structure, so that when the transmission rod 601 moves, it drives the transmission tube 605 to slide in the transmission groove 603, thereby causing the transmission rod 601 to rotate.

[0050] In an embodiment further provided by the present invention, the power-off assembly also includes a first bevel gear 606 connected to one end of the transmission rod 601, and the first bevel gear 606 is meshed with a second bevel gear 607, and the lower end of the second bevel gear 607 is fixedly connected to a gear shaft 608, and the lower end of the gear shaft 608 is rotatably matched with the inside of the busbar 200, and a transmission gear 609 is provided in the middle of the gear shaft 608, and the transmission gear 609 is meshed with a gear plate 610.

[0051] In an embodiment further provided by the present invention, one side surface of the tooth plate 610 is slidably connected to one side surface inside the busbar 200, one end of the tooth plate 610 is fixedly connected to a connecting strip 700, one end of the connecting strip 700 is connected to a conductive plate 701, and the other side surface of the busbar 200 is provided with a second slot 203, and the conductive plate 701 slidably cooperates with the second slot 203.

[0052] Specifically, due to the locking effect of the first bevel gear 606 and the second bevel gear 607, when power is turned on, the conductive plate 701 can remain locked and will not shake randomly to cause poor circuit contact, thereby stabilizing the circuit.

[0053] A junction box includes the above-mentioned pull-out mechanism and a cabinet body 100. A cabinet door 101 is hingedly connected to one side surface of the cabinet body 100 through a hinge. A plurality of pulleys 102 are respectively provided on the upper and lower surfaces of the cabinet body 100. The upper surface of the upper track 204 is fixedly connected to the upper surface inside the cabinet body 100. The lower surface of the lower track 205 is fixedly connected to the lower surface inside the cabinet body 100. A handle 201 is provided on one side surface of the junction plate 200. A power supply board 703 is provided on one side surface of the cabinet body 100. A plurality of power supply ports 704 are provided on the surface of the power supply board 703. A plurality of wiring terminals 702 are provided on one side surface of the conductive plate 701. The plurality of wiring terminals 702 are respectively plugged into the plurality of power supply ports 704.

[0054] Furthermore, the surface of the busbar 200 is provided with a first busbar 303, a detection module 305, a fuse 306 and a second busbar 309 in sequence from top to bottom. The surface of the busbar 200 is also provided with a controller 300, a lightning arrester 301 and a circuit breaker 302. A first wire 304 is connected between the first busbar 303 and the detection module 305, a second wire 307 is connected between the detection module 305 and the fuse 306, and a third wire 308 is connected between the fuse 306 and the second busbar 309.

[0055] Furthermore, all the above-mentioned electronic components are integrated on the conductive plate 701 through electrical connections via wires, and are connected to the energy storage system through the conductive plate 701.

[0056] In the present invention, the cabinet body 100 is first embedded into the energy storage system cabinet through the pulley 102 for installation. During inspection and maintenance, the staff first opens the cabinet door 101, and then uses the handle 201 to pull out the busbar 200. When pulling, the thumb is used to press the pressing block 400 and keep pressing. After the pressing block 400 is pressed, it drives the driving rod 404 to move inward, thereby pushing the driving plate 405 to slide inward. When the driving plate 405 slides, it drives the driving tube 406 to slide on the unlocking groove 501, so that the unlocking plate 500 moves downward along the direction of the unlocking groove 501, so that the unlocking rod 502 descends, thereby driving the locking rod 504 to pull the locking plate 505 down, so that the locking plate 505 is disengaged from the upper track 204 and no longer engages in an arc shape. Thereby, the lock of the upper track 204 on the busbar 200 is released, allowing the busbar 200 to slide freely; when the driving plate 405 slides, it will also synchronously drive the connecting rod 600 to move inward, thereby driving the transmission tube 605 to slide in the transmission groove 603, so that the transmission rod 601 rotates to drive the first bevel gear 606 to rotate, and the first bevel gear 606 rotates to drive the second bevel gear 607 to rotate, so that the transmission gear 609 rotates to drive the tooth plate 610 to slide inward, thereby driving the terminal 702 on the conductive plate 701 to leave the power supply port 704, so that the busbar cabinet is automatically powered off, so that the staff will not be at risk of electric shock during inspection and maintenance. During inspection and maintenance, the staff can stop pressing the pressing block 400 at any time, so that under the action of the reset spring 402 and the recovery spring 503, the unlocking plate 500 slides upward again and engages in the upper track 204, and the busbar 200 is locked again, so that the busbar 200 can stay in any position for inspection and remain stable without sliding back and forth.

[0057] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
