Description

[0001] The present invention relates to the technical field of power distribution networks, and in particular to a mobile distribution box. Background Art

[0002] At present, vehicle-mounted mobile energy storage systems have developed rapidly in China in recent years, and many domestic research institutions and enterprises are conducting research. In the existing technology, in the face of emergency power supply for important meetings or large-scale events, regular power maintenance, seasonal short-term peak loads of medium and low voltage distribution networks, and short-term summer peak loads, some research institutions and enterprises have developed vehicle-mounted mobile energy storage power supply cabins and achieved certain results.

[0003] At the same time, technologies related to the flexible parallel operation of multiple cabins can improve the reliability of on-board mobile energy storage power cabins, reducing the size and weight of the device while meeting the requirements of modular redundant design. However, on the one hand, when the line connecting the cabin to the grid side or the load side is short, the original line needs to be disassembled and replaced with a long wire. In emergency rescue or emergency power supply situations, this increases working time and causes greater losses. On the other hand, traditional parallel wiring solutions have certain defects. When the cabin adopts a three-phase four-wire system, additional neutral and ground wires need to be installed. When wiring in parallel, a large number of wires are used, which increases working time and workload.

[0004] Therefore, there is an urgent need to propose a new type of mobile distribution box to solve the above problems. Summary of the Invention

[0005] In view of this, the present invention proposes a mobile distribution box, which aims to solve the problem of using a mobile distribution box to realize parallel connection of multiple devices such as converters and mobile energy storage power supply cabins.

[0007] The line storage box is arranged directly below the adapter box, and spare wires and tools are arranged in the line storage box. The spare wires are used to connect the converter or mobile energy storage power supply cabin with the wiring terminals, and the spare wires are also used to connect the grid side and the load side with the wiring terminals.

[0008] Furthermore, the adapter box and the wire storage box each include a top cover, which is hinged to the adapter box and the wire storage box. The upper edges of the open ends of the adapter box and the wire storage box are provided with sealing rubber rings, which are used to prevent the adapter box and the wire storage box from dust and water.

[0009] Furthermore, a socket is provided on the side wall of the adapter box.

[0010] Furthermore, a groove is provided on the top cover of the wire storage box, and the lower side surface of the adapter box is clamped in the groove.

[0013] Furthermore, a processing unit is provided in the adapter box, the processing unit is connected to the cooling fan, and the processing unit is used to control the speed of the cooling fan according to formula (1):

[0014]

[0015] Among them, V is the rotation speed of the cooling fan, q v is the volume flow rate of the cooling fan, D is the outer diameter of the cooling fan, d is the hub diameter of the cooling fan, η is the volume efficiency of the cooling fan, A is the cross-sectional area of ​​the cooling fan, α is the maximum thickness of the cooling fan blade, b is the chord length of the cooling fan blade, t △ is the air temperature outside the transfer box, and t is the temperature between the two arc-shaped partitions.

[0016] Furthermore, the arc-shaped partition maintains a preset curvature, and the arc tops of the two arc-shaped partitions are arranged opposite to each other, and the curvature of the arc-shaped partition is determined according to formula (2):

[0017]

[0018] Among them, n is the arc of the arc partition, L is the length of the arc partition, r is the radius of the arc partition, s △ is the air flow rate between the two arc-shaped partitions when the cooling fan is turned off, s is the air flow rate between the two arc-shaped partitions when the cooling fan is turned on, t1 is the temperature between the two arc-shaped partitions when the cooling fan is turned on, and t0 is the preset working temperature between the two arc-shaped partitions.

[0019] Furthermore, a temperature sensor is provided between the two arc-shaped partitions for collecting temperature data between the two arc-shaped partitions in real time.

[0020] Furthermore, a filter is provided between the ventilation hole and the heat dissipation fan, and the filter is used for dust prevention.

[0021] Compared with the prior art, the beneficial effect of the present invention lies in that, by arranging wiring terminals on the adapter box, and the wiring terminals are respectively connected to the grid side and the load side, and are also connected to the converter or the mobile energy storage power supply cabin, it is possible to flexibly connect multiple machines in parallel for equipment such as the converter and the mobile energy storage power supply cabin, thereby reducing the number of wires used, saving resources, and reducing work intensity and improving work efficiency.

[0022] Furthermore, by setting up a wire storage box to place spare wires, the spare wires can be taken out at any time to connect the terminal blocks and equipment such as converters and mobile energy storage power supply cabins. By using the spare wires as extension wires, when the line connecting the converter or mobile energy storage power supply cabin to the grid side or the load side is short, there is no need to disassemble the original line to replace the long wire. You only need to take out the spare wires and use them. This can reduce working time and reduce losses in emergency rescue or emergency power supply situations. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] See Figure 2 As shown, the converter or mobile energy storage power supply cabin 1 in this embodiment can also be provided with multiple, and the number of converter or mobile energy storage power supply cabins 1 can be set according to actual conditions. Specifically, one side of the mobile distribution box 2 is electrically connected to several converters or mobile energy storage power supply cabins 1, which are preferably connected by wires, and a grounding cable is provided between the converter or mobile energy storage power supply cabin 1 and the mobile distribution box 2. The other side of the mobile distribution box 2 is electrically connected to the grid side 3 and the load side 4, respectively, and is also preferably connected by wires, and several converters or mobile energy storage power supply cabins 1 are electrically connected to the mobile distribution box 2 in parallel, and the two can be flexibly connected. By providing a mobile distribution box 2, it is possible to quickly and effectively connect several converters or mobile energy storage power supply cabins 1 to the grid side 3 and the load side 4. Not only is the wiring method flexible, but it is also possible to achieve parallel connection of multiple devices such as converters and mobile energy storage power supply cabins, thereby reducing the number of wires used, saving resources, and reducing work intensity and improving work efficiency.

[0035] Combine Figure 3-6As shown, the mobile distribution box 2 in the above embodiment includes an adapter box 5 and a wire storage box 6. The adapter box 5 and the wire storage box 6 are preferably square box structures, both of which have cavities inside to accommodate components. Specifically, the adapter box 5 and the wire storage box 6 each include a top cover 8, which is hinged to the adapter box 5 and the wire storage box 6. The adapter box 5 and the wire storage box 6 are preferably openable and closable boxes. Both are provided with a top cover 8 that can be flipped over on the upper side. By rotating the top cover 8, the adapter box 5 and the wire storage box 6 are closed into a sealed box. The top cover 8 is connected to the box body via a hinge 16.

[0036] Specifically, a sealing rubber ring 17 is provided between the top cover 8 and the box body of the adapter box 5 and the wire storage box 6. By providing the sealing rubber ring 17, when the top cover 8 is closed, it is sealed with the box body to prevent the adapter box 5 and the wire storage box 6 from dust and water.

[0037] Specifically, the side walls of the transfer box 5 are provided with wiring terminals 7, which are connected to the grid side 3 and the load side 4, respectively. Specifically, the wiring terminals 7 are used to connect to the grid side 3 and the load side 4, respectively, preferably connected together by wires. The wiring terminals 7 are also connected to the converter or mobile energy storage power supply cabin 1, specifically, the wiring terminals 7 are also connected to the converter or mobile energy storage power supply cabin 1 by wires.

[0038] Specifically, the wiring terminals 7 can be provided on the side wall of the adapter box 5 so that the converter or the mobile energy storage power supply cabin 1 is connected to the wiring terminals 7 through wires.

[0039] Specifically, the wiring terminals 7 include outgoing and incoming terminals, each of which is located on the side wall of the transfer box 5. Specifically, when a converter or mobile energy storage power supply cabin 1 is connected to the wiring terminals 7, several converters or mobile energy storage power supply cabins 1 are connected to the wiring terminals 7 in parallel. The wiring terminals 7 include incoming and outgoing terminals, each of which is evenly arranged and located on the side wall of the transfer box 5 or within the transfer box 5.

[0040] Specifically, the interface box 5 is provided with a terminal block 15 and a ground cable 14. The terminal block 15 is laid on the inner bottom surface of the interface box 5, and the ground cable 14 is connected to the terminal block 15. The terminal blocks 7 are respectively connected to the terminal block 15. The terminal block 15 is preferably a three-phase four-wire terminal block.

[0041] Specifically, a socket 18 is provided on the side wall of the adapter box 5. A socket 18 is provided on the side wall of the adapter box 5 adjacent to the side wall where the connection terminal 7 is located. The socket 18 is preferably a five-hole USB outdoor waterproof socket.

[0042] Specifically, the wire storage box 6 is positioned below or to the side of the adapter box 5. Spare wires are located within the wire storage box 6. These spare wires are used to connect the converter or mobile energy storage power supply cabin 1 to the terminal blocks 7. These spare wires serve as extension wires. That is, when connecting the converter or mobile energy storage power supply cabin 1 to the terminal blocks 7, if the distance between them is long, the spare wires can be removed from the wire storage box 6 for connection. This allows for quick connection between the converter or mobile energy storage power supply cabin 1 and the terminal blocks 7, even at long distances, improving work efficiency.

[0043] Specifically, the wire storage box 6 can be arranged directly below the adapter box 5, and the two can be stacked together; alternatively, the wire storage box 6 can be arranged on the side of the adapter box 5, that is, the two can be arranged side by side.

[0044] Specifically, a groove is provided on the upper side of the wire storage box 6 , that is, a groove is provided on the top cover 8 of the wire storage box 6 , and the size of the groove is equal to that of the adapter box 5 , so that the adapter box 5 is easily clamped on the wire storage box 6 .

[0045] Specifically, the top covers 8 of the interface box 5 and the line storage box 6 are provided with handles 13, and the top covers 8 are moved by the handles 13. At the same time, the line storage box 6 is provided with handles 13 on the opposite side walls, and the handles 13 on the opposite side walls of the line storage box 6 are used to carry the line storage box 6.

[0046] It can be seen that by providing a terminal block 7 on the transfer box 5, and the terminal block 7 is connected to the grid side 3 and the load side 4 respectively, and is also connected to the converter or mobile energy storage power supply cabin 1, it is possible to flexibly connect multiple machines in parallel with the converter, mobile energy storage power supply cabin and other equipment, thereby reducing the number of wires used, saving resources, and reducing work intensity and improving work efficiency. By providing a wire storage box 6 to place spare wires, the spare wires can be taken out at any time to connect the terminal block 7 and the converter, mobile energy storage power supply cabin and other equipment. By using the spare wires as extension wires, when the line connecting the converter or mobile energy storage power supply cabin 1 to the grid side 3 or the load side 4 is short, there is no need to disassemble the original line to replace the long wire. It is only necessary to take out the spare wire and use it. In situations such as emergency rescue or emergency power supply, working time can be reduced and losses can be reduced.

[0047] Specifically, tools are provided in the storage box 6 for use in wiring or maintenance. Specifically, a partition is provided in the storage box 6 to divide the internal space of the storage box 6 into two parts, one part for placing spare wires and the other part for placing tools.

[0048] Continue reading Figure 1 and 2As shown, in the specific implementation of the above embodiment, the adapter box 5 can be installed between the grid side 3 and the converter or mobile energy storage power supply cabin 1. The adapter box 5 can also be installed between the load side 4 and the converter or mobile energy storage power supply cabin 1. When the length of the cable 21 between the grid side 3 and the converter or mobile energy storage power supply cabin 1 is insufficient, the cable 21 is disassembled and connected to the incoming wiring terminal 7 of the mobile distribution box 2 to become the cable 22. The cable 23 is taken out of the storage box 6 and connected between the outgoing wiring terminal 7 of the mobile distribution box 2 and the converter or mobile energy storage power supply cabin 1 to extend the wiring.

[0049] If the cable 24 between the load side 4 and the converter or mobile energy storage power supply cabin 1 is not long enough, the cable 24 is disassembled and connected to the incoming wiring terminal 7 of the mobile distribution box 2 to become the cable 25. Cable 23 is taken out of the storage box 6 and connected between the outgoing wiring terminal 7 of the mobile distribution box 2 and the converter or mobile energy storage power supply cabin 1 to extend the cable.

[0050] Using a mobile distribution box 2, two or more converters or mobile energy storage power supply cabins 1 can be connected in parallel. Cables 22 are drawn from the grid side 3 and connected to the incoming wiring terminals 7 of the mobile distribution box 2. Cables 23 are drawn from the incoming and outgoing wiring terminals 7 of the mobile distribution box 2 and connected to the converter or mobile energy storage power supply cabin 1. Cables 25 are drawn from the outgoing wiring terminals 7 of the mobile distribution box 2 and connected to the load side 4. This allows for the parallel operation of multiple converters or cabins.

[0051] It can be seen that in this embodiment, a spare wire can be provided in the mobile distribution box 2 to serve as an extension wire. The mobile distribution box 2 can also realize flexible parallel connection of multiple devices such as converters and mobile energy storage power supply cabins.

[0052] In another preferred implementation manner based on the above embodiment, when the above embodiment is implemented, since the adapter box 5 is provided with circuits and terminal blocks 7, a certain amount of heat will be generated when the circuits are working. Moreover, since the adapter box 5 is a sealed box, when the heat inside it accumulates, the temperature will continue to rise, thereby causing safety accidents such as damage to the internal circuits and fire, thereby affecting the normal operation of the circuits. Based on this, this implementation manner can also be implemented in the following manner.

[0053] See Figure 7 and Figure 8 As shown, ventilation holes 9 are provided on the two opposite side walls of the adapter box 5, and two arc-shaped partitions 10 are provided between the two ventilation holes 9. The two arc-shaped partitions 10 are arranged side by side and opposite to each other, and the ventilation holes 9 are located between the two arc-shaped partitions 10. Through the arrangement of the two arc-shaped partitions 10, a ventilation duct is formed, thereby facilitating air to enter and exit the ventilation holes 9 and circulate between the two arc-shaped partitions 10, so as to facilitate heat dissipation inside the adapter box 5.

[0054] Specifically, the terminal blocks 7 and wiring circuits are disposed between the two arc-shaped partitions 10, and a cooling fan 12 is provided on the ventilation holes 9 to ventilate and dissipate heat from the terminal blocks 7 and wiring circuits. The cooling fan 12 is provided to drive airflow, thereby facilitating air circulation between the two arc-shaped partitions 10 and improving heat dissipation efficiency.

[0055] Specifically, when implementing the above embodiment, a processing unit 19 is provided within the adapter box 5 to control the cooling fan 12. The cooling fan 12 includes a drive motor, and the processing unit 19 is connected to the drive motor to control it. The processing unit 19 is preferably an MCU, a single-chip microcomputer, or a PLC system.

[0056] Specifically, the processing unit 19 is connected to the cooling fan 12, and the processing unit 19 is used to control the speed of the cooling fan 12 according to formula (1):

[0057]

[0058] Wherein, V is the rotation speed of the cooling fan 12, q v is the volume flow of the cooling fan 12, D is the outer diameter of the cooling fan 12, d is the hub diameter of the cooling fan 12, η ​​is the volume efficiency of the cooling fan 12, A is the cross-sectional area of ​​the cooling fan 12, α is the maximum thickness of the fan blade of the cooling fan 12, b is the chord length of the fan blade of the cooling fan 12, t △ is the temperature outside the transfer box 5, and t is the temperature between the two arc-shaped partitions 10.

[0059] It can be seen that by determining the rotation speed of the cooling fan 12 based on the air temperature outside the adapter box 5 and the temperature data between the two arc-shaped partitions 10, the rotation speed of the cooling fan 12 can be effectively controlled so that it can effectively dissipate the heat in the space between the two arc-shaped partitions 10, thereby reducing the consumption of electricity, saving energy, and greatly improving the heat dissipation efficiency.

[0060] Specifically, the arc-shaped partition 10 maintains a preset curvature, and the arc tops of the two arc-shaped partitions 10 are arranged opposite to each other. The curvature of the arc-shaped partition 10 is determined according to formula (2):

[0061]

[0062] Wherein, n is the radian of the arc partition 10, L is the length of the arc partition 10, r is the radius of the arc partition 10, s △is the air flow rate between the two arc-shaped partitions 10 when the cooling fan 12 is turned off, s is the air flow rate between the two arc-shaped partitions 10 when the cooling fan 12 is turned on, t1 is the temperature between the two arc-shaped partitions 10 when the cooling fan 12 is turned on, and t0 is the preset working temperature between the two arc-shaped partitions 10.

[0063] It can be seen that by determining the curvature of the arc partition 10 based on the air flow rate ratio when the cooling fan 12 is turned off and on, and the ratio of the temperature between the two arc partitions 10 when the cooling fan 12 is turned on to the preset working temperature, the curvature of the arc partition 10 can be effectively set, so that the air between the two arc partitions 10 can flow effectively, thereby improving the heat dissipation efficiency in the adapter box 5.

[0064] Specifically, a temperature sensor 20 is provided between the two arc-shaped partitions 10 for real-time acquisition of temperature data between the two arc-shaped partitions 10. The temperature sensor 20 is electrically connected to the processing unit 19 for real-time data transmission.

[0065] Specifically, a filter screen 11 is provided on the ventilation hole 9 . The mesh size of the filter screen 11 is smaller than the size of the dust particles, and dust prevention is performed through the filter screen 11 .

[0066] Specifically, the filter 11 is arranged between the ventilation hole 9 and the heat dissipation fan 12. The heat dissipation fan 12 can be provided with one, which is arranged at one of the ventilation holes 9, or two, which are respectively arranged on the two ventilation holes 9.

[0067] It is understandable that, in the specific implementation of the above embodiment, when the connection terminals 7 are arranged on the side wall of the adapter box 5 , the ventilation holes 9 and the connection terminals 7 are arranged in a position that avoids each other.

[0068] It can be seen that in the above embodiment, by providing the ventilation holes 9 and the cooling fan 12, the heat inside the adapter box 5 can be effectively dissipated, thereby improving safety.

[0069] Specifically, handles 13 are provided on the box bodies and bottom covers of the adapter box 5 and the wire storage box 6 to facilitate carrying the adapter box 5 and the wire storage box 6 and opening and closing the top cover 8 .
