DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] Embodiment 1: The present invention provides a microgrid intelligent box transformer, such as Figures 1 to 7 As shown, it comprises: a box body 1, a solar panel 2 is symmetrically mounted on the top of the box body 1, a top cover 3 is slidably mounted on the top of the solar panel 2, and eight storage compartments 4 are opened inside the box body 1;

[0030] A heat dissipation component 5 is installed at the top of the inner wall of the box body 1. The heat dissipation component 5 includes a rectangular plate 51 fixedly installed on the top of the inner wall of the box body 1. Eight guide tubes 52 are installed on the top of the rectangular plate 51, and the air inlets of the guide tubes 52 are respectively located in the middle of the tops of the eight placement bins 4. The eight placement bins 4 are respectively provided with substation equipment, distribution equipment, power consumption equipment, photovoltaic equipment, energy storage equipment, charging equipment, discharge equipment, and battery detection equipment. Among them, the substation equipment is a transformer, which is used to convert the electricity generated by the power generation system into electricity suitable for subsequent power grids or users, and convert high voltage electricity into low voltage electricity. The distribution equipment covers a variety of equipment such as circuit breakers, switches, and distribution boxes, which are used to distribute and control the flow of electricity to ensure that electricity can be safely transmitted and distributed in the power grid. The power consumption equipment and various power load terminals are used to directly consume electricity. The photovoltaic equipment is also called photovoltaic power generation equipment, which mainly includes solar panels 2, inverters, etc. At this time, the inverter is installed and placed inside the bin 4. By Energy can be converted into electrical energy to achieve solar power generation. Energy storage equipment: includes batteries, capacitors and other components, which are used to store energy, smooth power supply, and improve the flexibility and stability of the energy system. Charging equipment refers to the relevant equipment of electric vehicle charging stations, including charging interfaces, charging control and management equipment, etc., which are used to charge electric vehicles. Discharging equipment: In new energy microgrids, energy storage equipment can discharge when the power is sufficient to provide power to the power grid or load. This part of the equipment mainly refers to devices such as inverters that use discharge and discharge control management. Battery detection equipment: used to monitor the status information of energy storage batteries to ensure their safe operation. A guide plate 53 is fixedly installed between the tops of the eight guide tubes 52, a guide cover 54 is fixedly installed on the top of the guide plate 53, and a cooling fan 59 is installed at the bottom of the inner wall of the guide cover 54. An air outlet tunnel is opened inside the guide plate 53 at the air outlet position corresponding to the guide tube 52. The top of the guide plate 53 is located at the top of the air outlet tunnel and is movably connected with a baffle plate 514.

[0031] like Figure 5 and Figure 6As shown, mounting blocks 55 are symmetrically mounted on the top of the inner wall of the air guide cover 54, a same placement box 56 is mounted between the two mounting blocks 55, a fire extinguishing agent is arranged inside the placement box 56, an electromagnetic valve 58 is embedded and mounted on the bottom edge of the placement box 56, a smoke sensor 57 is mounted on the middle of the bottom end of the mounting block 55, a cooling fan 2 510 located at the top position of the cooling fan 1 59 is fixedly mounted inside the air guide cover 54, and the rotation direction of the cooling fan 2 510 and the cooling fan 1 59 are opposite;

[0032] The smoke content in the gas is detected by the smoke sensor 57. When the smoke content exceeds the threshold value, the electromagnetic valve 58 is opened. When the electromagnetic valve 58 is opened, the fire extinguishing agent inside the placement box 56 enters the inside of the guide cover 54. At this time, the cooling fan 2 510 is running. When the cooling fan 2 510 is running, the fire extinguishing material is guided into the placement bin 4. At this time, the fire inside the placement bin 4 is extinguished, and the cooling fan 1 59 drives the hot air inside the placement bin 4 to flow, thereby accelerating the heat dissipation inside the placement bin 4 and improving the heat dissipation effect inside the placement bin 4.

[0033] like Figure 5 and Figure 6 As shown, positioning blocks 512 are symmetrically fixedly installed inside the air outlet tunnel of the guide plate 53, a heat-conducting cover 511 is installed between the two positioning blocks 512, a lifting plate 513 is movably connected up and down inside the heat-conducting cover 511, the top of the lifting plate 513 is fixedly connected to the bottom of the blocking plate 514, and an air bag 515 is fixedly installed between the bottom of the lifting plate 513 and the top of the inner wall of the heat-conducting cover 511;

[0034] As the gas heats up, the volume of the gas inside the airbag 515 increases. After the airbag 515 expands, it drives the lifting plate 513 to rise. When the lifting plate 513 rises, it drives the blocking plate 514 to rise. At this time, the spacing between the tops of the air outlet tunnels is increased. After one of the lifting plates 513 rises, it squeezes the gas at the top of the heat-conducting cover 511, so that the gas at the top of the heat-conducting cover 511 enters the inside of the remaining heat-conducting covers 511 along the connecting pipe 516. At this time, the lifting plate 513 inside the heat-conducting cover 511 is driven to descend, resulting in a decrease in the spacing between the tops of the remaining air outlet tunnels. At the same time, the air output of multiple air outlet tunnels is changed, thereby changing the internal heat dissipation speed, further preventing the electronic components inside the placement bin 4 from being damaged due to the inability to cool down quickly.

[0035] like Figure 5 and Figure 6 As shown, the number of heat-conducting covers 511 is set to eight in total, and the same connecting pipe 516 is connected through the tops of the outer surfaces of the eight heat-conducting covers 511, and a sealing ring is provided at the connection between the connecting pipe 516 and the heat-conducting covers 511, and the connecting pipe 516 is fixedly installed inside the guide plate 53;

[0036] The sealing ring increases the sealing performance of the connection between the connecting pipe 516 and the heat-conducting cover 511, thereby preventing the problem of gas leakage between the connection between the connecting pipe 516 and the heat-conducting cover 511. In addition, the connecting pipe 516 enables the gas inside the multiple heat-conducting covers 511 to flow, thereby reducing the difficulty of gas flow inside the multiple heat-conducting covers 511.

[0037] like Figure 3 and Figure 7 As shown, an opening and closing assembly 6 is fixedly installed at the bottom end of the top cover 3, and the opening and closing assembly 6 includes a mounting plate 61 fixedly installed at the bottom end of the top cover 3, and one end of the mounting plate 61 is symmetrically and movably connected with a flip rod 64, and the same connecting rod 65 is movably connected between the two flip rods 64, and two electric telescopic rods 66 are symmetrically and fixedly installed on the top of the connecting rod 65;

[0038] The electric telescopic rod 66 is connected to a power source and starts to operate. When the electric telescopic rod 66 operates, it drives the connecting rod 65 to move. When the connecting rod 65 moves, it drives the bottom end of the flip rod 64 to rotate and move. When the bottom end of the flip rod 64 rotates and moves, it drives the top end of the flip rod 64 to deflect and move. When the top end of the flip rod 64 moves, it drives the mounting plate 61 to move. When the mounting plate 61 moves, it drives the top cover 3 to move. After the top cover 3 moves, the heat dissipation component 5 is exposed to the outside, thereby facilitating the maintenance of the inside of the heat dissipation component 5.

[0039] like Figure 3 and Figure 7 As shown, four threaded rods 62 are connected through the inside of the mounting plate 61, and the top of the threaded rod 62 is fixedly connected to the bottom end of the top cover 3, and the outer side of the threaded rod 62 is threadedly connected to a nut 63 that fits the bottom end surface of the mounting plate 61, and the top of the electric telescopic rod 66 is fixedly installed with a rectangular block 67, and the rectangular block 67 is fixedly installed on the top of the inner wall of the box body 1;

[0040] By rotating the nut 63, the nut 63 moves along the outside of the threaded rod 62, thereby abutting the bottom end of the mounting plate 61, so that the mounting plate 61 and the bottom end of the top cover 3 are squeezed and fixed, and the electric telescopic rod 66 is fixed under the action of the rectangular block 67, which changes the difficulty of fixing the electric telescopic rod 66 and prevents the electric telescopic rod 66 from shaking.

[0041] Working principle: In actual use of the device, by rotating the nut 63, the nut 63 moves along the outer side of the threaded rod 62, thereby abutting the bottom end of the mounting plate 61, so that the mounting plate 61 and the bottom end of the top cover 3 are squeezed and fixed, and then the electric telescopic rod 66 is connected to the power supply and starts to operate. When the electric telescopic rod 66 is in operation, it drives the connecting rod 65 to move, and when the connecting rod 65 moves, it drives the bottom end of the flip rod 64 to rotate and move, and when the bottom end of the flip rod 64 rotates and moves, it drives the top end of the flip rod 64 to deflect and move, and when the top end of the flip rod 64 moves, it drives the mounting plate 61 to move, and when the mounting plate 61 moves, it drives the top cover 3 to move, so that the two top covers 3 fit each other, and at this time, the top end of the heat dissipation component 5 can be protected to prevent foreign objects from falling to the top end of the heat dissipation component 5, which causes the top end of the heat dissipation component 5 to be disturbed by dirt, further ensuring the cleanliness of the inside of the heat dissipation component 5, and not hindering the flow of gas inside the heat dissipation component 5;

[0042] Then, the substation equipment, the power distribution equipment, the power consumption equipment, the photovoltaic equipment, the energy storage equipment, the charging equipment, the discharging equipment and the battery detection equipment are installed in the storage compartment 4 respectively. At this time, the multifunctional conversion is realized by the substation equipment, the power distribution equipment, the power consumption equipment, the photovoltaic equipment, the energy storage equipment, the charging equipment, the discharging equipment and the battery detection equipment;

[0043] Finally, the cooling fan 59 is running. When the cooling fan 59 is running, the gas is driven to flow along the inside of the guide tube 52 of the rectangular plate 51, and enters the inside of the guide plate 53 along the inside of the guide tube 52, and enters the inside of the guide cover 54 along the guide plate 53, and finally enters the connection between the solar panel 2 and the top cover 3 along the top of the guide cover 54, and is dissipated to the outside along the connection, which can facilitate the diversion of the heat generated by the electronic components in the multiple storage compartments 4 inside the box body 1 when they are running, reduce the interference of heat on the electronic components, thereby protecting the electronic components and increasing the service life of the electronic components.

[0044] Then, when smoke appears in the heat dissipation gas, the smoke content in the gas is detected by the smoke sensor 57. When the smoke content exceeds the threshold, the electromagnetic valve 58 is opened. When the electromagnetic valve 58 is opened, the fire extinguishing agent in the placement box 56 enters the inside of the guide cover 54. At this time, the heat dissipation fan 2 510 is running and the heat dissipation fan 1 59 is turned off. When the heat dissipation fan 2 510 is running, the fire extinguishing material is guided into the inside of the placement bin 4. At this time, the inside of the placement bin 4 is extinguished, which greatly improves the efficiency of fire extinguishing and reduces the risk of fire spreading. At the same time, the fire extinguishing agent can be more accurately guided to the fire point, thereby improving the effect of fire extinguishing.

[0045] Finally, since the electronic components inside one of the placement bins 4 generate high temperature due to the load, the temperature of the gas inside the corresponding flow guide tube 52 rises. After the temperature of the gas rises, the volume of the gas inside the airbag 515 increases. After the airbag 515 expands, it drives the lifting plate 513 to rise. When the lifting plate 513 rises, it drives the blocking plate 514 to rise. At this time, the distance between the top of the wind outlet tunnel becomes larger. After one of the lifting plates 513 rises, it squeezes the gas at the top of the heat conductive cover 511, so that the gas at the top of the heat conductive cover 511 enters the inside of the other heat conductive covers 511 along the connecting pipe 516. At this time, the lifting plate 513 inside the heat conductive cover 511 is driven to descend, resulting in a decrease in the distance between the tops of the other wind outlet tunnels, and at the same time, the air volume of multiple wind outlet tunnels is changed, thereby changing the internal The heat dissipation speed can further prevent the electronic components inside the placement bin 4 from being damaged due to the inability to cool down quickly. By automatically adjusting the height of the lifting plate 513 inside the heat-conducting cover 511, the heat dissipation effect can be intelligently adjusted. When it is found that the electronic components inside a placement bin 4 need more heat dissipation due to the high temperature generated by the load, the design can respond quickly to improve the heat dissipation effect of the area, and can also redistribute the airflow to accelerate the drainage of hot air, so that the temperature of the entire internal environment is more uniform, reducing the risk of damage caused by local overheating, and does not rely on the problem of insufficient cooling caused by the inability of traditional fans to adjust immediately when the external control unit is started. Temperature self-regulation is achieved through natural airflow and intelligent control, thereby saving electricity consumption.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
