Description
Technical Field
[0001] This utility model relates to the field of energy storage cabinets, and more specifically, it relates to an energy storage cabinet that is easy to maintain. Background Technology
[0002] An energy storage cabinet is a highly integrated electrical energy storage device that integrates core components such as battery packs, battery management systems (BMS), energy management systems (EMS), temperature control systems, fire protection systems, and power distribution equipment into a sealed cabinet through standardized and modular design. By controlling charge and discharge, it enables flexible storage and release of electrical energy, effectively regulating the imbalance between power supply and demand, improving grid stability, and enhancing the absorption capacity of renewable energy. Its applications are wide-ranging, covering grid-side peak and frequency regulation, user-side peak and valley electricity pricing management, off-grid power supply, and backup power for special scenarios such as 5G base stations and data centers.
[0003] Currently, to facilitate the maintenance of energy storage cabinets, the internal electrical components and battery modules are generally installed using a drawer-type structure. When the cabinet door is opened, the corresponding drawer-type modules can be pulled out for convenient maintenance, improving maintenance efficiency. However, energy storage cabinets contain high-voltage electrical components. If the front door is a drawer type, operators may accidentally pull out modules due to accidentally touching the drawer handle during routine inspections, causing electric shock or equipment failure. If the drawer-type modules are fixed separately, it will increase the workload of the staff during maintenance, thus failing to achieve the purpose of facilitating maintenance as mentioned above.
[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes an energy storage cabinet that is easy to maintain. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an energy storage cabinet that is easy to maintain.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy storage cabinet that is easy to maintain, comprising a cabinet body, the cabinet body being provided with a front door and a rear door; the front door is used for operating and viewing the internal equipment, and the rear door is used for maintenance; the cabinet body is provided with electrical components and battery modules, and both the electrical components and battery modules adopt a drawer-type installation structure, which can only be pulled out when the rear door is opened.
[0007] Preferably, multiple guide rails A for sliding sliders A are arranged in a vertical array on both sides of the cabinet, and drawer plates are fixedly connected between the sliders A. The electrical components and battery modules are installed on the drawer plates, and handles A are installed on the drawer plates to facilitate their pulling out.
[0008] Preferably, the front door is hinged to the front end of the cabinet, and the rear door is divided into two symmetrical panels. The rear of the cabinet is opened by moving the panels laterally, and the panels are equipped with handles B for easy movement.
[0009] Preferably, guide rails B are installed on both sides of the top of the cabinet for sliding the slider B, the partition plate is fixed to the bottom of the slider B, and the partition plates are fixed together by fixing components.
[0010] Preferably, the fixing component includes a magnet A fixed to the surface of one of the sub-plates, and a magnet B fixed to the other sub-plate and capable of contacting the magnet A.
[0011] Preferably, the fixing component includes a connecting plate A fixed on one of the sub-plates and a connecting plate B fixed on the other sub-plate. A screw is fixedly connected to the surface of the connecting plate A, and a through hole is provided on the connecting plate B for the screw to pass through.
[0012] Preferably, multiple temperature sensors are arranged in a vertical array on both sides of the cabinet and alternately with the guide rail A. An alarm is installed at the bottom of the cabinet, and the signal output terminal of the temperature sensor is connected to the signal input terminal of the alarm located at the top of the cabinet.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. Because this utility model does not have an additional complex fixing structure, it greatly reduces the workload of the staff. The maintenance personnel can directly repair the faulty parts, thus achieving the purpose of convenient maintenance. At the same time, the design of separating the functions of the front and rear doors not only ensures the safety of daily operation, but also ensures the efficiency of maintenance work. This solves the problem of the drawer-type front door in the background technology, as well as the problem of increasing the workload of the staff by fixing the drawer-type module separately.
[0015] 2. The vertically arrayed temperature sensors in this utility model can cover different height areas of the cabinet, and can accurately monitor the temperature changes of key heat-generating components such as electrical components and battery modules. Compared with single-point monitoring, it greatly improves the comprehensiveness and accuracy of temperature data acquisition. Once the temperature sensor detects that the temperature in a certain area exceeds the preset threshold, it immediately transmits the signal to the bottom alarm, triggering an audible and visual alarm to remind maintenance personnel to handle the problem in a timely manner and shorten the fault response time.
[0016] 3. The horizontal pulling opening method of this utility model allows the rear door to fit snugly against the side of the cabinet after opening, without occupying the space behind the cabinet. In narrow or space-limited installation environments, there is no need to reserve a large amount of space behind the door for opening. Attached Figure Description

[0024] like Figure 1-5 As shown, this utility model provides an energy storage cabinet that is easy to maintain, including a cabinet body 1, the cabinet body 1 is provided with a front door 2 and a rear door 3; the front door 2 is used to operate and view the internal equipment, and the rear door 3 is used for maintenance; the cabinet body 1 is provided with electrical components and battery modules, and the electrical components and battery modules adopt a drawer-type installation structure, which can only be pulled out when the rear door 3 is opened.
[0025] In daily use, operators can access the energy storage cabinet and check its status by opening the front door 2. Since the drawer-type structure cannot be pulled out from the front door 2, it prevents accidental removal of internal electrical components or battery modules due to accidental contact, reducing the risk of electric shock or equipment malfunction. When maintenance is required, maintenance personnel open the rear door 3, and the drawer-type electrical components and battery modules inside the cabinet 1 can be easily pulled out along the tracks. Therefore, this utility model, by not setting up an additional complex fixing structure, greatly reduces the workload of staff, allowing maintenance personnel to directly inspect faulty components, achieving convenient maintenance. Furthermore, the separate design of the front and rear doors 3 ensures both the safety of daily operation and the efficiency of maintenance work.
[0026] The following is a pull-out installation structure: Multiple guide rails A4 are arranged vertically on both sides of cabinet 1 for sliding sliders A5. Drawer panels 6 are fixedly connected between sliders A5. Electrical components and battery modules are mounted on drawer panels 6. A handle A12 is installed on drawer panels 6 for easy pulling out. Pulling drawer panel 6 backward via handle A12 causes sliders A5 to move along the guide rails A4. With the rear door 3 open, drawer panels 6 can be pulled out from the rear of cabinet 1 for inspection of electrical components and battery modules. After inspection, drawer panels 6 are pushed back into cabinet 1. Once fully pushed in, sliders A5 move to the front of guide rails A4 and cannot move further forward, preventing them from being pulled out from the front of cabinet 1. At this point, the rear panel is closed, and the rear door 3 holds the drawer panels 6 in place, thus securing them stably. Individual fixing of each drawer panel 6 is not required.
[0027] Furthermore, multiple temperature sensors 10 are arranged in a vertical array on both sides of the cabinet 1, alternating with the guide rail A4. An alarm 11 is installed at the bottom of the cabinet. The signal output terminal of the temperature sensor 10 is connected to the signal input terminal of the alarm 11 located at the top of the cabinet 1. The vertically arrayed temperature sensors 10 can cover different height areas of the cabinet 1, and can accurately monitor the temperature changes of key heat-generating components such as electrical components and battery modules. Compared with single-point monitoring, this greatly improves the comprehensiveness and accuracy of temperature data acquisition. Once the temperature sensor 10 detects that the temperature in a certain area exceeds the preset threshold, it immediately transmits the signal to the alarm 11 at the bottom, triggering an audible and visual alarm to remind maintenance personnel to handle the situation in a timely manner and shorten the fault response time.
[0028] The front door 2 of this utility model is hinged to the front end of the cabinet 1 (a common connection method for the front door 2 in the prior art). The rear door 3 is divided into two symmetrical panels 301. The rear of the cabinet 1 is opened by moving the panels 301 laterally. The panels 301 are equipped with handles B13 for easy movement. The lateral pulling opening method allows the panels 301 to fit tightly against the side of the cabinet 1 after opening, without occupying the space behind the cabinet 1. In narrow or space-limited installation environments, it is not necessary to reserve a large amount of space behind for opening the door (only a straight distance for the drawer to be pulled out needs to be left behind the cabinet 1, and the staff can carry out maintenance from the side of the drawer panel 6).
[0029] The following is the specific structure for lateral movement: Guide rails B7 for sliding sliders B8 are installed on both sides of the top of cabinet 1. The partition plate 301 is fixed to the bottom of slider B8. The partition plates 301 are fixed together by fixing components 9. Specifically, by pushing the two partition plates 301 with the handle B13, they can move to either side or towards the center. Each partition plate 301 then drives a single slider B8 to slide along a single guide rail B7, maintaining the linear movement of the partition plate 301 relative to cabinet 1. When the two partition plates 301 move towards the center and their sides press against each other, closing the back door 3 of cabinet 1, the two sliders B8 also reach the outermost parts of the two guide rails B7. At this point, the fixing components 9 fix the two partition plates 301 in place, thus fixing their positions (the two partition plates 301 fixed together, combined with the guide rails B7 restricting the sliders B8, prevents both from moving to either side).
[0030] This utility model provides two structures for the fixing component 9:
[0031] The first type of fixing component 9 includes a magnet A901 fixed to the surface of one of the partition plates 301, and a magnet B902 fixed to the other partition plate 301 and capable of contacting the magnet A901.
[0032] When the two partition plates 301 move towards the middle and their sides stick together to close the back door 3 of the cabinet 1, magnets A901 and B902 come into contact and fix the two partition plates 301 with magnetic force. Pulling the two plates together will release the fixation between them. The operation is simple and does not require any fixing operation, making it convenient.
[0033] The second type of fixing component: the fixing component 9 includes a connecting plate A903 fixed on one of the sub-plates 301 and a connecting plate B904 fixed on the other sub-plate 301. A screw 905 is fixedly connected to the surface of the connecting plate A903, and a through hole 906 is provided on the connecting plate B904 for the screw 905 to pass through.
[0034] When the two partition plates 301 are moved towards the middle and their sides are pressed together to close the rear door 3 of the cabinet 1, the screw 905 on the connecting plate A903 passes through the through hole 906 on the connecting plate B904. Then, the nut is installed on the screw 905 to fix the connecting plate A903 and the connecting plate B904, thereby fixing the two partition plates 301. Removing the nut will release the fixation of the two partition plates 301. Compared with the first fixing component, which is fixed by the thread of the nut, its fixation is more reliable and not easy to loosen, but it requires a fixing operation. Users can choose to apply it according to the actual situation.
[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
