Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage cabinets and relates to a waterproof device for an external antenna of an energy storage cabinet. Background Art

[0002] Energy storage cabinets are a type of equipment specially designed to store electrical energy. They have a wide range of application scenarios and play an important role in power systems, renewable energy utilization, home backup power supplies, and specific industry applications. Energy storage cabinets are of great significance to improving energy utilization efficiency, promoting the popularization of renewable energy, and enhancing the flexibility and reliability of power systems through their high-efficiency energy storage and release capabilities. As charging and discharging equipment, energy storage cabinets require real-time monitoring of the status of the equipment, and corresponding adjustments to internal strategies in different seasons and different local electricity policies. All of these are inseparable from the reception and transmission of signals. Stable signals directly affect the user experience and the monitoring and maintenance of the equipment by cloud platform personnel. Adding antennas to the cabinets and placing them on the outside of the cabinets can effectively solve this problem. At this time, the problem of waterproofing the antenna holes will arise, as will the function and stability of the waterproofing device.

[0003] However, the existing energy storage cabinet antennas generally have a protruding waterproof structure on the outside of the cabinet side or the antenna is set inside the cabinet. When multiple energy storage cabinets are combined, the protruding waterproof structure requires a wider gap between the cabinets, which occupies a larger area and wastes space; and setting the antenna inside the cabinet will cause delays, interruptions, or even no signal reception in the cabinet. In addition, the energy storage cabinet is installed with antenna equipment before leaving the factory. The antenna equipment is outside the cabinet, so packaging and transportation may damage the antenna equipment. When the antenna equipment is installed at the customer site, it is necessary to disassemble and assemble parts, re-wire, fix, and hide the wires, etc., which is inefficient and the quality of on-site installation cannot be guaranteed.

[0004] Therefore, a waterproof device for an external antenna of an energy storage cabinet is needed to solve the above technical problems, which can ensure effective waterproofing, be flexible and convenient to install, and not be affected by cabinet combination. Utility Model Content

[0028] The fixed connection methods between the antenna installation cavity 2 and the sealing plate 3 include: threaded connection, welding, and riveting; the fixed connection methods between the external antenna 7 and the energy storage cabinet 1 include: threaded connection, magnetic adsorption connection, hanging, and bundling connection.

[0029] Furthermore, the outer side of the sealing plate 3 can be detachably connected to an antenna mounting plate 8, and the antenna mounting plate 8 is arranged in a canopy-like cover above the second wiring hole 6 of the sealing plate 3; the antenna mounting plate 8 can be selected according to actual on-site needs. For example, it can be selected in the case of a single cabinet and heavy rainfall outdoors, but it does not need to be selected in the case of indoors or combined cabinets.

[0030] Furthermore, the antenna mounting plate 8 can be detachably connected to the outer side surface of the sealing plate 3 by means of threaded connection or snap-on connection.

[0031] Furthermore, the snap-on hanging method includes: the antenna mounting plate 8 is provided with a hook 9 extending vertically downward toward the side of the sealing plate 3, and a hanging groove 10 is provided on the outer side surface of the sealing plate 3, and the hook 9 matches the hanging groove 10.

[0032] Furthermore, the bottom of the wiring window 4 is opened to the inner bottom surface of the antenna installation cavity 2, and the inner bottom surface of the antenna installation cavity 2 is provided with a slope that is higher inside and lower outside. A drainage hole 11 is provided at the lower part of the sealing plate 3, and the drainage hole 11 is directly opposite to the wiring window 4. The lowest point of the drainage hole 11 is not higher than the outer edge of the inner bottom surface of the antenna installation cavity 2; the lowest point of the drainage hole 11 is not higher than the bottom of the wiring window 4; the inner bottom surface of the antenna installation cavity 2 is provided with a slope to facilitate the rapid discharge of drifting rain or accumulated water in the antenna installation cavity 2, and the drainage hole 11 is lower than the inner bottom surface of the antenna installation cavity 2 and the bottom of the wiring window 4 to facilitate the drainage of drifting rain or accumulated water in the antenna installation cavity 2, and then combined with the flip-up cable entry cabinet of the external antenna 7, the first wiring hole 5 of the cable flip-up cabinet is waterproofly sealed and blocked, which further improves the protection level of the antenna waterproof device.

[0033] Furthermore, a side wall of the antenna installation cavity 2 on the side where the wiring window 4 is opened is provided with an annular flange 12 extending outwardly and parallel to the inner side of the sealing plate 3. After the antenna installation cavity 2 is inserted into the installation window opened on the side wall of the energy storage cabinet 1 from the outside to the inside, the flange 12 is blocked and abutted against the outer wall of the energy storage cabinet 1, the sealing plate 3 is threadedly connected to the flange 12, and the flange 12 is threadedly connected to the outer wall of the energy storage cabinet 1; the flange 12 is blocked and abutted against the installation window of the antenna installation cavity 2, so that the water flow path when the antenna waterproof device drains water outward no longer flows through the gap that may penetrate into the energy storage cabinet 1, thereby improving the protection level between the antenna waterproof device and the inner and outer walls of the energy storage cabinet 1.

[0034] Furthermore, a rubber gasket 13 is provided between the flange 12 and the outer wall of the energy storage cabinet 1 ; after the rubber gasket 13 is compressed, the waterproofness and sealing between the antenna waterproof device and the outer wall of the energy storage cabinet 1 are further improved.

[0035] Furthermore, the rubber gasket 13 is annular, and the shape of the rubber gasket 13 is the same as that of the flange 12 .

[0036] Furthermore, the flange 12 is formed by bending the inner wall of the antenna installation cavity 2 outwardly through sheet metal; the integrated sheet metal has lower cost and better waterproof performance.

[0037] Furthermore, the first wiring hole 5, the second wiring hole 6, and the wiring window 4 are respectively provided with protective coils; the protective coils can effectively prevent the cables of the external antenna 7 from suffering friction loss or even damage when passing through the edges of the first wiring hole 5, the second wiring hole 6, and the wiring window 4.

[0038] Example

[0039] Before the specific installation of the external antenna waterproof device of the energy storage cabinet, the external antenna 7 is disassembled, and the antenna seat part is temporarily stored in the antenna installation cavity 2. Most of the structures and line parts of the external antenna 7 have been assembled in the factory. When the energy storage cabinet 1 is transported to the site for installation, it is only necessary to pass the cable of the external antenna 7 through the second wiring hole 6, the wiring window 4, and the first wiring hole 5 in sequence and turn it up to connect it to the inside of the energy storage cabinet 1. The cable connection can be completed by connecting the cable end of the external antenna 7 inside the energy storage cabinet 1, and then the external antenna 7 is fixed on the antenna installation plate 8. The protective coils respectively arranged in the second wiring hole 6, the wiring window 4, and the first wiring hole 5 can effectively prevent the cable of the external antenna 7 from friction loss or even damage. The embedded antenna installation cavity 2 and the upturned wiring method make the antenna waterproof device have a higher protection level, which can effectively prevent drifting rain or accumulated water from penetrating into the energy storage cabinet 1.
