Description

Technical Field

[0001] This application relates to the technical field of high-voltage equipment, and in particular to a rack-mounted energy storage high-voltage box. Background Technology

[0002] Rack-mounted energy storage units with high-voltage boxes, as a type of power equipment integrating advanced energy storage devices and high-voltage control units, play a crucial role in efficient and reliable energy storage and management. These devices are commonly found in various application scenarios with stringent requirements for energy storage and management, such as data centers, communication base stations, and renewable energy generation systems.

[0003] From a technical perspective, traditional high-voltage enclosure designs typically include a robust enclosure and a removable door. One side of the door is hinged to the enclosure, while the other side is secured with a conventional locking mechanism. To facilitate direct monitoring of the internal operating status by maintenance personnel, the door often features an observation window, which is fixed using specialized adhesive bonding technology to ensure excellent sealing and stability. Inside the enclosure, a series of key components are carefully arranged, including circuit breakers, pre-charge relays, fuses, shunts, pre-charge resistors, battery cluster management units (BCUs), and switching power supplies. These components work together to ensure the stable operation and efficient management of the high-voltage enclosure.

[0004] However, in actual deployment and operation, especially in complex and ever-changing environments such as construction sites, the design of traditional observation windows reveals certain limitations. Faced with the continuous effects of external factors such as wind pressure and vibrations from various equipment operating at construction sites, the fixed structure of the observation window may encounter challenges, with the adhesive joints potentially loosening or even becoming damaged. This not only affects maintenance personnel's real-time assessment of the internal status but may also pose a potential threat to the overall stability and safety of the high-voltage box, indicating room for improvement. Utility Model Content

[0005] The purpose of this application is to provide a rack-mounted energy storage high-voltage box to solve the problem that the observation window may become loose or even fall off when the above-mentioned high-voltage box is used on the construction site.

[0006] The rack-mounted energy storage unit with high-voltage belt provided in this application adopts the following technical solution:

[0007] A rack-mounted energy storage box with high voltage includes a box body and a box door. One side of the box door is hinged to the box body, and the other side of the box door is provided with a locking element. The box door is detachably connected to the box body through the locking element. An observation port is provided on the box door. A limiting frame is fixed around the outer edge of the observation port on the side of the box door facing the box body. An observation window is provided on the side of the box door facing the box body, located within the limiting frame. A baffle plate is fixed on the side of the limiting frame away from the box door to limit the movement of the observation window. The sides of the box door and the baffle plate that are close to each other abut against the two sides opposite to the observation window.

[0008] By adopting the above technical solution, during the installation of the observation window, due to the installation of the baffle plate and the limiting frame, the observation window is pre-inserted into the inside of the limiting frame, and then the baffle plate is fixed on the limiting frame to limit the side of the observation window away from the box door, thereby improving the installation stability of the observation window and reducing the possibility of the observation window loosening or falling off when used in the high-voltage box.

[0009] Optionally, an elastic sealing strip is fixedly provided on the outer edge of the observation window away from the box door, and the side of the elastic sealing strip away from the box door abuts against the side of the barrier plate facing the box door.

[0010] By adopting the above technical solution, due to the installation of the elastic sealing strip, after the observation window is installed, one side of the elastic sealing strip presses against the observation window, while the side of the elastic sealing strip away from the door abuts against the barrier plate, thereby improving the installation stability of the observation window.

[0011] Optionally, a traction rod is hinged to the bottom side of the box body in a horizontal direction, and a fixing pin is fixed to the end of the traction rod away from the box body; a traction plate is fixed to the side of the box door facing the box body in a horizontal direction, and an adjustment slot is opened on the traction plate along its own length for the fixing pin to be inserted and slid.

[0012] By adopting the above technical solution, the combination of the traction rod, fixing pin and traction plate limits the opening angle range of the box door, reduces the possibility of damage to the box door due to excessive rotation, and improves the service life of the high-voltage box.

[0013] Optionally, the box body is provided with a support assembly, which includes four vertically arranged vertical rods and several horizontally arranged horizontal rods. The two ends of the horizontal rods are fixedly connected to the outer peripheral surfaces of the adjacent vertical rods, and the two ends of the vertical rods are fixedly connected to the upper and lower sides of the box body.

[0014] By adopting the above technical solution, due to the application and setting of the support components, a combination structure of vertical and horizontal bars is fixedly installed inside the box, thereby improving the structural strength of the box and reducing the possibility of deformation of the high-voltage box due to pressure, thus improving the overall structural stability of the high-voltage box.

[0015] Optionally, the box body is provided with several symmetrical limiting rods along the horizontal direction. Two vertical rods on the same side form a group. The two ends of the limiting rods are respectively fixedly connected to the outer circumferential surfaces of the two vertical rods in the same group. Limiting notches are provided on the sides of the two limiting plates that are close to each other.

[0016] By adopting the above technical solution, due to the symmetrical arrangement of the limiting rod, the battery pack and other electrical equipment can be inserted into the limiting notch on the limiting rod during the installation of the battery pack and other electrical equipment inside the enclosure, which facilitates the placement and installation of the relevant electrical equipment.

[0017] Optionally, a number of casters with locking function are fixed on the bottom side of the exterior of the housing.

[0018] By adopting the above technical solution, when the high-voltage box needs to be moved a short distance, due to the installation of casters on the bottom of the box, a single person can push the high-voltage box with the help of the casters, thereby reducing the time required for short-distance movement of the high-voltage box and improving the corresponding movement efficiency.

[0019] Optionally, a number of heat dissipation holes are provided on the side wall of the enclosure.

[0020] By adopting the above technical solutions, the possibility of overheating of the battery pack and other electrical equipment installed inside the enclosure is reduced, and the heat dissipation performance of the high-voltage box is improved during application.

[0021] Optionally, a sealing strip that can abut against the door is fixed on the outer edge of the opening of the box body facing the door.

[0022] By adopting the above technical solution, when the cabinet door is closed, due to the application of the sealing strip on the cabinet body, the side of the sealing strip away from the cabinet body is pressed against the inner side of the cabinet door.

[0023] Optionally, a number of wiring ports are provided on the bottom side of the housing, and a flexible wire protection sleeve is embedded in the inner wall of the wiring port.

[0024] By adopting the above technical solution, the combination of the connection port and the flexible protective sleeve on the inner wall of the connection port not only facilitates the connection of the cable, but also effectively reduces the possibility of wear on the outer insulation of the cable.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. During the installation of the observation window, the observation window is pre-inserted into the inside of the limiting frame, and then the baffle plate is fixed on the limiting frame to limit the side of the observation window away from the box door. This improves the installation stability of the observation window and reduces the possibility of the observation window loosening or falling off when used in the high-voltage box.

[0027] 2. Due to the application of support components, a combination structure of vertical and horizontal bars is fixedly installed inside the box to improve the structural strength of the box and reduce the possibility of deformation of the high-voltage box under pressure, thereby improving the overall structural stability of the high-voltage box.

[0036] The present application will be further described in detail below with reference to all the accompanying drawings.

[0037] Example:

[0038] Reference Figure 1 and Figure 2A rack-mounted energy storage box with high voltage includes a box body 1 and a box door 2. One side of the box door 2 is hinged to the box body 1, and the other side of the box door 2 is provided with a locking element 3. The box door 2 is detachably connected to the box body 1 through the locking element 3. The locking element 3 is a conventional lock structure, which will not be described in detail here.

[0039] The locking element 3 is connected to a connecting rod 31, which is slidably mounted on the inner side of the door 2 in the vertical direction. A pulley 32 is fixed at the end of the connecting rod 31 away from the locking element 3. When the door 2 is closed to the box body 1, the locking tongue (not shown in the figure) in the locking element 3 and the pulley 32 at the end of the connecting rod 31 slide into the inner edge of the opening of the box body 1, providing a locking force in the vertical direction.

[0040] Reference Figure 2 , Figure 3 and Figure 4 An observation port 21 is provided on the door 2. A limiting frame 22 is fixed to the side of the door 2 facing the box body 1 by screws around the outer edge of the observation port. An observation window 4 is provided on the side of the door 2 facing the box body 1, located inside the limiting frame 22. A baffle plate 23 is fixed to the side of the limiting frame 22 away from the door 2 by screws to limit the observation window 4. An elastic sealing strip 24 made of rubber is fixed to the outer edge of the side of the observation window 4 away from the door 2.

[0041] After the observation window 4 is installed, the box door 2 and the elastic sealing strip 24 approach each other and abut against the two opposite sides of the observation window 4, while the side of the elastic sealing strip 24 away from the box door 2 abuts against the barrier plate 23, thereby improving the installation stability of the observation window 4.

[0042] Reference Figure 3 A traction rod 5 is hinged horizontally on the bottom side inside the box 1, and a fixing pin 51 is fixed at the end of the traction rod 5 away from the box 1; a traction plate 25 is fixed horizontally on the side of the box door 2 facing the box 1, and an adjustment groove 251 is opened on the traction plate 25 along its own length for the fixing pin 51 to be inserted and slid; this limits the opening range of the box door 2 and reduces the possibility of damage to the box door 2 due to excessive rotation.

[0043] A sealing strip 11, which can abut against the door 2, is fixed on the outer edge of the opening of the box body 1 facing the door 2. The sealing strip 11 is made of rubber. When the door 2 is closed, the side of the sealing strip 11 away from the box body 1 abuts against the inner side of the door 2.

[0044] Reference Figure 5 Four universal wheels 12 with locking function are fixed to the bottom side of the outer side of the box 1 by screws, which facilitates short-distance movement of the high-voltage box; a number of heat dissipation holes 13 are evenly opened on the side wall of the box 1 to improve the heat dissipation performance of the high-voltage box during application.

[0045] Two wiring ports 14 are provided on the bottom side of the housing 1, and a flexible rubber cable sleeve 15 is embedded on the inner wall of the wiring port 14 to reduce the possibility of wear on the outer insulation of the cable.

[0046] Reference Figure 5 and Figure 6 The enclosure 1 is equipped with a support assembly 6, which includes four vertically arranged vertical rods 61 and several horizontally arranged horizontal rods 62. The two ends of the horizontal rods 62 are fixedly connected to the outer circumference of the adjacent vertical rods 61 by screws, and the two ends of the vertical rods 61 are fixedly connected to the upper and lower sides of the enclosure 1. This is to increase the overall structural strength of the high-voltage box and enhance its structural stability.

[0047] The housing 1 is provided with several symmetrically arranged limiting rods 63. Two vertical rods 61 on the same side form a group. The two ends of the limiting rods 63 are respectively fixedly connected to the outer circumference of the two vertical rods 61 in the same group by screws. The limiting rods 63 are installed in the horizontal direction. Limiting notches 631 are opened on the sides of the two opposing limiting plates that are close to each other. The battery pack and other electrical equipment can be inserted into the limiting notches 631 to facilitate the placement and installation of related electrical equipment.

[0048] The implementation principle of this application embodiment is as follows:

[0049] During the application of this high-voltage box, it can move quickly over short distances by installing casters 12, increase the overall structural strength of the high-voltage box by supporting components 6, and limit the opening range of the box door 2 by the combination of traction rod 5 and traction plate 25.

[0050] In addition, after the observation window 4 is installed, the box door 2 and the elastic sealing strip 24 approach each other and abut against the two opposite sides of the observation window 4, while the side of the elastic sealing strip 24 away from the box door 2 abuts against the barrier plate 23, which enhances the installation stability of the observation window 4.
