Technical Field
[0001] The utility model relates to the technical field of power equipment, in particular to a power supply with an Ethernet interface. Background Technique
[0002] With the continuous development of science and technology and the progress of society, the power industry has also developed rapidly. Distributed power sources mainly refer to power sources for renewable energy power generation such as wind energy, solar energy, water energy, natural gas, geothermal energy, ocean energy, and biomass energy. After a large number of distributed power sources are connected to the power grid, they have a certain impact on the power grid. Therefore, it is necessary to monitor the voltage, current, active power, reactive power, power factor, etc. at the grid connection point and send the relevant electrical quantity data to the local power dispatching department. The power dispatching department remotely controls the operation of the power grid circuit through the telecontrol system. Therefore, a large number of secondary devices are required in the existing grid-connected circuits, and a special interface device is needed for centralized processing, which is widely used in the power industry.
[0003] The existing patent number CN218385985U discloses a distributed power grid connection interface device, including a housing, a protective cover, and a movable plate. Clamping blocks are fixedly connected to the upper and lower ends of the housing, a clamping groove is fixedly connected to the top of the movable plate, a connecting block is fixedly connected below the movable plate, a connecting rod is fixedly connected to the central part of the inner wall of the connecting block, a limiting groove is fixedly connected to the outer wall of the connecting rod, a heat dissipation hole is fixedly connected to the back of the housing, a fan is fixedly connected to one side of the heat dissipation hole, a control board is fixedly connected to the surface of the protective cover. The control board improves the convenience of the device, facilitates the management of operators, and the quick disassembly and assembly mechanism improves the work efficiency of the staff, enables the housing and the protective cover to be stably connected, and can also conveniently disassemble the protective cover. The heat dissipation mechanism improves the functionality of the device, enhances the convenience and practicality of use, can protect the internal components from damage, and increases the service life of the device.
[0004] The above-mentioned existing technical solutions have the following defects: In many cases, distributed power sources need to be installed outdoors. There are holes such as limiting holes and heat dissipation holes on the housing, and the protective cover is snap-connected to the housing, and there is no blocking facility at the joint seam. It is very easy for external water vapor and impurities to invade the interior of the power supply, which greatly affects the safe use of the equipment. Content of the Utility Model
[0005] The purpose of the utility model is to provide a power supply with an Ethernet interface.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] It includes a power supply housing, inside which several electronic components are fixedly installed. A first heat sink plate is penetrated through the bottom wall of the power supply housing, and the electronic components are installed on one side of the first heat sink plate embedded inside the housing. A second heat sink plate is embedded in the side wall of the power supply housing, and a third heat sink plate is fitted and installed on the top wall of the power supply housing. A number of heat dissipation fins are extended on the outer walls of the first heat sink plate, the second heat sink plate and the third heat sink plate. A main wire harness is externally connected to the outer wall of the power supply housing, and the main wire harness is electrically connected to the electronic components. The end of the main wire harness is connected with a waterproof box body, and several sub-wire harnesses are externally connected to the waterproof box body. An inspection opening is provided on the outer wall of the power supply housing, and a sealing cover plate for covering the inspection opening is hinged on the outer wall of the power supply housing. A first rubber sealing ring surrounding the inspection opening is fixedly installed on the outer wall of the power supply housing. A first fitting groove for cooperating with the first rubber sealing ring is provided on the outer wall of the sealing cover plate, and a buckling fastener is provided for the sealing cover plate.
[0008] By adopting the above technical solutions, the sub-wire harnesses include functional wire harnesses such as the wire harness connecting the power generation equipment, the communication wire harness, the wire harness accessing the power grid, etc. When the power access line is working, the heat generated by the electronic components inside the battery housing will first be transferred to the first heat sink plate, and then dissipated to the external environment through the first heat sink plate and the heat dissipation fins. The heat accumulated inside the battery housing will be dissipated to the external environment through the second heat sink plate, the third heat sink plate and the heat dissipation fins. The accumulated heat inside the power supply housing is quickly removed through direct and indirect double heat dissipation, greatly reducing the temperature inside the power supply housing, ensuring that the equipment is in a good working environment. The sealing cover plate cooperates with the fastener to tightly fasten the power supply housing, firmly embedding the first sealing rubber ring into the first fitting groove to effectively fill the joint between the sealing cover plate and the inspection opening. At the same time, a waterproof box body with an externally connected main wire harness is adopted to keep the battery housing in a sealed and low-temperature working environment all the time, which can effectively prevent external water vapor and impurities from invading the power supply internally and ensure the long-term stable operation of the power supply.
[0009] Furthermore, the first heat sink plate, the second heat sink plate, the third heat sink plate and the heat dissipation fins are internally hollow and interconnected, and a certain amount of alcohol solution is filled inside.
[0010] By adopting the above technical solutions, alcohol has good volatility. When absorbing heat locally, it will quickly absorb heat and evaporate, quickly transferring the heat to other places with lower temperatures, and then liquefying and releasing heat to reflow, achieving the effect of rapid heat conduction and effectively improving the heat conduction rate of the first heat sink plate, the second heat sink plate, the third heat sink plate and the heat dissipation fins.
[0011] Further, the waterproof box body includes a first junction box and a second junction box for fixedly connecting the main wire harness. The outer wall of the first junction box is provided with a network port and a pair of power-on slots. The second junction box is arranged at one end where the branch wire harnesses are aggregated. The outer wall of the first junction box is provided with a network connector matching the network port and a power connection contact matching the power-on slot. A second rubber sealing ring surrounding the network port and the power-on slot is fixedly arranged on the side of the first junction box close to the second junction box. The outer wall of the second junction box is provided with a second fitting groove for fitting the waterproof rubber ring. The first junction box is detachably arranged in fit with the second junction box.
[0012] By adopting the above technical solution, the power-on slot and the power connection contact facilitate the connection of the circuit wire harness. The network port and the network connector comply with the Ethernet protocol, facilitating the real-time upload of data such as voltage, current, active power, reactive power, and power factor to the computer center of the power dispatching department. When the first junction box and the second junction box are fixedly installed in fit, the second rubber sealing ring can effectively fill the gap between the two in cooperation with the second fitting groove. At the same time, the rubber material has good insulation, ensuring the dry and sealed docking of each interface and maintaining a good working environment.
[0013] Further, a pair of positioning plates fitting the second junction box are extendedly arranged on the outer wall of the first junction box. A locking bolt is rotatably arranged in the positioning plate in a clamping manner. One end of the locking bolt passes through the positioning plate and is threadedly connected to the second junction box. A sealing ring wrapping the port of the second junction box is fixedly arranged on the outer edge of the second junction box. The sealing ring covers the joint of the first junction box and the second junction box.
[0014] By adopting the above technical solution, when the locking bolt is tightened, the positioning plate is closely attached to the second junction box, and the first junction box and the second junction box are firmly installed in close contact. Loosening the locking bolt can quickly release the docking, facilitating the installation and disassembly of the waterproof box body. The sealing ring covering the joint of the two further isolates the intrusion of external water vapor and impurities into the waterproof box body, improving the overall sealing performance of the device and ensuring the long-term stable operation of the interface.
[0015] In summary, the beneficial technical effects of the present utility model are as follows:
[0016] 1. The first heat sink plate, the second heat sink plate, the third heat sink plate, the heat dissipation fins, the waterproof box body, and the sealing cover plate are adopted, so as to create a working environment in which the battery shell is always kept airtight and at a low temperature, and at the same time effectively prevent external water vapor and impurities from invading the power supply, ensuring the long-term stable operation of the power supply;
[0017] 2. The first junction box, the second junction box, the second rubber sealing ring, and the second fitting groove are adopted, so as to ensure the dry and sealed docking of each interface and maintain a good working environment;
[0018] 3. The positioning plate, locking bolts and sealing rings are adopted, thus further isolating the intrusion of external water vapor and impurities into the waterproof box body and improving the overall sealing performance of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to Figures 1-5 , the present utility model provides the following technical solutions:
[0029] It includes a power supply housing 1, and several electronic components 2 are fixedly installed inside the power supply housing 1. A first heat sink plate 3 penetrates through the bottom wall of the power supply housing 1.

The sealing cover plate 9 is provided with a fastening buckle. The sub-wire harness 71 includes functional wire harnesses such as a wire harness connecting a power generation device, a communication wire harness, and a wire harness accessing the power grid. When the power access line is working, the heat generated by the electronic components 2 inside the battery housing will first be transferred to the first heat sink plate 3, and then dissipated to the external environment through the first heat sink plate 3 and the heat dissipation fins 6. The heat accumulated inside the battery housing will be dissipated to the external environment through the second heat sink plate 4, the third heat sink plate 5, and the heat dissipation fins 6. By directly and indirectly dissipating heat, the accumulated heat inside the power supply housing 1 is quickly removed, significantly reducing the temperature inside the power supply housing 1, ensuring that the device is in a good working environment. The sealing cover plate 9 is fastened to the power supply housing 1 with a buckle, firmly embedding the first sealing rubber ring into the first fitting groove 93 to effectively fill the joint between the sealing cover plate 9 and the inspection opening 91. At the same time, a waterproof box body 8 with an externally connected main wire harness 7 is used to keep the battery housing in a sealed and low-temperature working environment all the time, which can effectively prevent external water vapor and impurities from invading the power supply, ensuring the long-term stable operation of the power supply.
[0030] The first heat sink plate 3, the second heat sink plate 4, the third heat sink plate 5, and the heat dissipation fins 6 are internally hollow and interconnected, and are filled with a certain amount of alcohol solution. Alcohol has good volatility. When absorbing heat locally, it will quickly absorb heat and evaporate, quickly transferring the heat to other places with lower temperature, and then liquefying and releasing heat to flow back again, achieving the effect of rapid heat conduction and effectively improving the heat conduction rate of the first heat sink plate 3, the second heat sink plate 4, the third heat sink plate 5, and the heat dissipation fins 6.
[0031] The waterproof box body 8 includes a first junction box 81 and a second junction box 82 fixedly connected to the main wire harness 7. The outer wall of the first junction box 81 is provided with a network port 83 and a pair of power-on slots 84. The second junction box 82 is arranged at one end where the sub-wire harnesses 71 converge. The outer wall of the first junction box 81 is provided with a network connector 85 that mates with the network port 83 and a power connection contact 86 that mates with the power-on slot 84.

The network port 83 and the network connector 85 comply with the Ethernet protocol, facilitating the real-time upload of data such as voltage, current, active power, reactive power, and power factor to the computer center of the power dispatching department. When the first junction box 81 and the second junction box 82 are fixedly installed in contact, the second rubber sealing ring 87 can effectively fill the gap between the two in cooperation with the second fitting groove 88. At the same time, the rubber material has good insulation properties, ensuring the dry and sealed docking of each interface and maintaining a good working environment.
[0032] On the outer wall of the first junction box 81, a pair of positioning plates 10 that fit the second junction box 82 are extended. The positioning plates 10 are provided with locking bolts 11 in a snap-fit and rotatable manner. One end of the locking bolt 11 passes through the positioning plate 10 and is threadedly connected to the second junction box 82. A sealing ring 12 that wraps the port of the second junction box 82 is fixedly arranged on the outer edge of the second junction box 82. The sealing ring 12 covers the joint of the first junction box 81 and the second junction box 82. When the locking bolt 11 is tightened, the positioning plate 10 is closely attached to the second junction box 82, and the first junction box 81 and the second junction box 82 are firmly installed in close contact. When the locking bolt 11 is loosened, the docking can be quickly released, facilitating the installation and disassembly of the waterproof box body 8. The sealing ring 12 covering the joint between the two further isolates the intrusion of external water vapor and impurities into the interior of the waterproof box body 8, improving the overall sealing performance of the device and ensuring the long-term stable operation of the interfaces.
