Description

Technical Field

[0001] The present invention relates to the field of microgrid systems, and in particular to a new energy microgrid system device. Background Art

[0002] A new energy microgrid system is a small-scale power generation and distribution network that integrates distributed renewable energy (such as photovoltaic and wind power), energy storage devices, intelligent control equipment, and local loads. It can operate independently or be connected to the main power grid. Through an energy management system, it dynamically adjusts power generation, storage, and consumption to achieve efficient clean energy consumption, improve power supply reliability, and optimize grid interaction. It is particularly suitable for scenarios such as remote areas and industrial parks, supporting a low-carbon, flexible energy supply model.

[0003] In the existing technology, a complete new energy microgrid system is composed of a variety of power equipment, including power generation elements, energy storage equipment, power conversion hubs, power distribution infrastructure, etc., among which the energy storage equipment realizes the temporary storage function of electric energy through multiple energy storage basic units. The energy storage equipment needs to be equipped with an independent heat dissipation system, but when the battery cell components inside the small energy storage device are not fully used, they will also occupy the heat dissipation area. This causes conventional energy storage equipment to have insufficient utilization of its own heat dissipation system. In addition, for the bonded heat dissipation structure, it is impossible to ensure that the thermal conductivity effect remains stable each time due to the frequent movement of the battery cells. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a new energy microgrid system equipment to solve the problems raised in the above-mentioned background technology. When the battery cell assembly is pulled out from the inner side of the support mechanism, the present invention automatically seals the heat dissipation through-holes on both sides of the independent power supply interlayer, so that the air intake channel part will not transport the low-temperature airflow into the independent power supply interlayer, and only provides heat dissipation treatment for the area where the battery cell assembly is inserted, thereby improving the utilization rate of the heat dissipation system. Frequent plugging and unplugging of the battery cell assembly will not cause wear of the silicon pad mounted on the surface of the battery cell assembly or the surface of the heat conduction plate, thereby ensuring sufficient heat dissipation stability during subsequent long-term operation.

[0005] In order to achieve the above-mentioned objectives, the present invention is implemented through the following technical solutions: a new energy microgrid system device, comprising a microgrid system device body and a battery cell assembly, the microgrid system device body comprising an energy storage box, a support mechanism, a closing mechanism and a pushing mechanism, a plurality of independent power supply interlayers are provided inside the energy storage box, and adjacent independent power supply interlayers are separated by partitions, an air inlet channel is provided on one side of the shell of the energy storage box, an air outlet channel is provided on the other side of the shell of the energy storage box, a cooling fan is installed on the top of the energy storage box, and a heat dissipation port is connected to the top of the air outlet channel, a supporting mechanism is installed inside each of the independent power supply interlayers, the supporting mechanism is used to plug and store the battery cell assembly, the surface of the battery cell assembly is in contact with the inner wall of the supporting mechanism, a closing mechanism is inserted into the side of the supporting mechanism, the end of the closing mechanism is used to be embedded in the interior of the air inlet channel, and a pushing mechanism is installed at the inner rear end of the supporting mechanism, and the pushing mechanism is used to lean against the battery cell assembly.

[0006] Furthermore, the supporting mechanism includes a heat dissipation frame, a connecting port, a fixed heat conductive plate and a lifting heat conductive plate. The fixed heat conductive plate is installed at the inner bottom of the heat dissipation frame, and the lifting heat conductive plate is arranged at the inner top of the heat dissipation frame. Internal through holes are opened on both side surfaces of the heat dissipation frame, and grooves are opened on the sides of the battery cell assembly.

[0007] Furthermore, a fixed heat sink is inserted into the bottom end of the fixed heat conducting plate, a lifting heat sink is provided at the top end of the lifting heat conducting plate, a lifting groove is provided at the bottom of the partition, and the top of the lifting heat sink is embedded in the lifting groove, and the side edges of each lifting heat sink and fixed heat sink remain perpendicular to the connecting port.

[0008] Furthermore, a bottom groove is provided on the surface of the fixed heat conducting plate, a bayonet is installed at the bottom of the battery cell assembly, a ball is embedded at the bottom of the bayonet, and the battery cell assembly is embedded into the bottom groove through the bottom bayonet and the ball.

[0009] Furthermore, there are gaps between the side of the heat dissipation frame and the air inlet channel and the air outlet channel. The cold air blown in by the heat dissipation fan follows the air inlet channel, the cavity on one side of the heat dissipation frame, the connecting port, the heat sink, the cavity on the other side of the heat dissipation frame, and finally enters the air outlet channel.

[0010] Furthermore, the closing mechanism includes a trapezoidal plate, a movable plate and a sealing plate, the side of the trapezoidal plate is integrally formed with a movable plate, the top and bottom of the movable plate are welded with extension plates, the side of the extension plate is welded with a first spring, the side of the heat dissipation frame is provided with an internal through hole, and the surface of the air inlet channel and the air outlet channel is provided with an external through hole.

[0011] Furthermore, a linkage column is inserted into the surface of the movable plate, a sealing plate is welded to the end of the linkage column, the other end of the first spring is fixed to the surface of the heat dissipation frame, and the trapezoidal plate penetrates into the inner side of the heat dissipation frame from the inside of the inner through hole.

[0012] Furthermore, the grooves, inner through holes, outer through holes, trapezoidal plates and sealing plates on both sides of the battery cell assembly are all on the same horizontal plane, and the size of the sealing plate is the same as that of the outer through holes.

[0013] Furthermore, the pushing mechanism includes a rear push plate, a second spring and a scraping rod. The rear end of the heat dissipation frame is screwed with a telescopic channel. One end of the second spring is welded inside the telescopic channel, and the other end of the second spring is welded to the surface of the rear push plate. The two ends of the rear push plate are integrated with scraping rods, and the top of the scraping rod is integrated with a pushing inclined plate.

[0014] Furthermore, a pressure-bearing inclined plate is integrally formed at the rear end of the lifting heat conducting plate, and the pushing inclined plate is used to lean against the inclined surface of the pressure-bearing inclined plate. Thermal conductive silicon pads are mounted on the inner sides of the lifting heat conducting plate and the fixed heat conducting plate.

[0016] 1. The new energy microgrid system equipment is divided into multiple independent power supply interlayers inside the energy storage box, and a support structure is installed through the independent power supply interlayer to provide support for the battery cell assembly. The closing mechanism cooperates with the pushing mechanism at the rear end to automatically block the heat dissipation through-holes on both sides of the independent power supply interlayer when the battery cell assembly is pulled out from the inside of the support mechanism. This prevents the air intake channel from delivering low-temperature airflow into the independent power supply interlayer, and only provides heat dissipation to the area where the battery cell assembly is inserted, thereby improving the utilization rate of the heat dissipation system.

[0017] 2. In each supporting mechanism of the new energy microgrid system equipment, a movable heat-conducting plate structure is provided on the top. As the battery cell assembly is inserted, there will be no direct sliding friction contact with the surface of the lifting heat-conducting plate and the fixed heat-conducting plate during the insertion process. This ensures that even if the battery cell assembly is frequently plugged in and out, it will not cause wear on the surface of the battery cell assembly or the silicon pad mounted on the surface of the heat-conducting plate, ensuring sufficient heat dissipation stability during subsequent long-term operation.

[0018] 3. After the new energy microgrid system equipment inserts the battery cell assembly into the corresponding support mechanism, it will cooperate with the rear pushing mechanism to move backward. When the pushing mechanism completes the backward movement, the upper lifting heat conduction plate will automatically move down and press directly on the top of the battery cell assembly in a vertical motion state to achieve the effect of fitting and heat dissipation.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] See also Figures 1 to 8The present invention provides the following technical solutions: a new energy microgrid system device, including a microgrid system device body and a battery core assembly 7, the microgrid system device body includes an energy storage box 1, a supporting mechanism 6, a closing mechanism 9 and a pushing mechanism 17, a plurality of independent power supply interlayers 4 are provided inside the energy storage box 1, and adjacent independent power supply interlayers 4 are separated by partitions 5, an air inlet channel 2 is provided on one side of the shell of the energy storage box 1, an air outlet channel 3 is provided on the other side of the shell of the energy storage box 1, and a heat dissipation device is installed on the top of the energy storage box 1. A heat fan 33 is provided. The top of the air outlet channel 3 is connected to a heat dissipation port 34. A support mechanism 6 is installed inside each independent power supply interlayer 4. The support mechanism 6 is used to insert and store the battery cell assembly 7. The surface of the battery cell assembly 7 is in contact with the inner wall of the support mechanism 6. A closing mechanism 9 is installed on the side of the support mechanism 6. The end of the closing mechanism 9 is used to be embedded in the interior of the air inlet channel 2. A pushing mechanism 17 is installed on the inner rear end of the support mechanism 6. The pushing mechanism 17 is used to press against the battery cell assembly 7. The energy storage box 1 is used to store electrical energy in this new energy microgrid system device.

[0030] When the present invention is used, multiple battery cell assemblies 7 are installed in the independent power supply interlayer 4 inside the energy storage box 1, and each battery cell assembly 7 is supported by the support mechanism 6, and the heat dissipation structure on the outside of the support mechanism 6 is also used to achieve the heat dissipation purpose of the inserted battery cell assembly 7. A closing mechanism 9 is connected to one side of the support mechanism 6. When the battery cell assembly 7 is not inserted into the interior of the support mechanism 6, the pushing mechanism 17 at the rear end of the support mechanism 6 will push forward with the help of the second spring 28 at its rear end, and finally trigger the side closing mechanism 9 to be pushed out. With the help of the closing mechanism 9, the outer through hole 36 on the air intake channel 2 is sealed, thereby blocking the cavity inside the independent power supply interlayer 4 and the air intake channel 2, and finally preventing the heat dissipation airflow from passing through the outside of the support mechanism 6. After the battery cell assembly 7 is inserted, the closing mechanism 9 can be opened to achieve the heat dissipation effect of the cavity outside the support mechanism 6. After the battery cell assembly 7 is inserted, the heat conduction plate on the support mechanism 6 can also be automatically fitted to avoid sliding friction.

[0031] In this embodiment, the support mechanism 6 includes a heat dissipation frame 8, a communication port 10, a fixed heat conductive plate 13, and a lifting heat conductive plate 14. The fixed heat conductive plate 13 is mounted on the inner bottom of the heat dissipation frame 8, and the lifting heat conductive plate 14 is disposed on the inner top of the heat dissipation frame 8. Internal through-holes 31 are provided on both side surfaces of the heat dissipation frame 8, and grooves 19 are provided on the sides of the battery cell assembly 7. A fixed heat sink 12 is inserted into the bottom end of the fixed heat conductive plate 13, and a lifting heat sink 11 is provided on the top end of the lifting heat conductive plate 14. A lifting slot 15 is provided at the bottom of the partition 5, and the top of the lifting heat sink 11 is embedded in the lifting slot 15. The sides of each lifting heat sink 11 and fixed heat sink 12 remain perpendicular to the communication port 10. The surface of the fixed heat conducting plate 13 is provided with a bottom groove 32. A latch 18 is installed at the bottom of the battery cell assembly 7. A ball bearing is embedded in the bottom of the latch 18. The battery cell assembly 7 is inserted into the bottom groove 32 via the bottom latch 18 and the ball bearing. There are gaps between the sides of the heat dissipation frame 8 and the air inlet duct 2 and the air outlet duct 3. The cold air blown in by the cooling fan 33 flows sequentially along the air inlet duct 2, the cavity on one side of the heat dissipation frame 8, the connecting port 10, the heat sink, the cavity on the other side of the heat dissipation frame 8, and finally into the air outlet duct 3. After the battery cell assembly 7 is inserted into the corresponding support mechanism 6, it will cooperate with the rear push mechanism 17 to move backward. When the push mechanism 17 completes its backward movement, the upper lifting heat conducting plate 14 is automatically moved downward and directly pressed against the top of the battery cell assembly 7 in a vertical motion, achieving a close-fitting heat dissipation effect.

[0032] Specifically, in the initial state, the pushing mechanism 17 at the rear end partially lifts the lifting heat conducting plate 14 upwards. At this time, the distance between the lifting heat conducting plate 14 and the fixed heat conducting plate 13 is enlarged. In this state, when the battery cell assembly 7 is pushed from the outside to the inside of the heat dissipation frame 8, the bottom of the battery cell assembly 7 moves along the inside of the bottom slide groove 32 through the latch 18 and the ball at the bottom of the latch 18. Therefore, there is no direct contact between the bottom of the battery cell assembly 7 and the silicon pad on the surface of the fixed heat conducting plate 13. As for the top, since the lifting heat conducting plate 14 is in a lifted state, the battery cell assembly 7 will not come into contact with the bottom surface of the lifting heat conducting plate 14 until the battery cell assembly 7 pushes the pushing mechanism 17 toward the rear end and finally pushes The mechanism 17 moves to the rear end, at which time the lifting heat-conducting plate 14 will move downward, and eventually the thermally conductive silicon pad on the surface will be pressed against the top of the battery cell assembly 7, and a concave structure is provided below the end of the bottom slide 32, so that the latch 18 can be embedded in the bottom end of the bottom slide 32, so that the battery cell assembly 7 will sink, and eventually the bottom surface of the battery cell assembly 7 will be pressed and fitted with the thermally conductive silicon pad on the fixed heat-conducting plate 13, at this time the heat dissipation effect of the top and bottom surfaces of the battery cell assembly 7 can be achieved, and during the whole process the battery cell assembly 7 will not directly contact the thermally conductive silicon pad in any area, wherein the lifting process of the lifting heat-conducting plate 14 will perform lifting and limiting movement inside the lifting slot 15 through the lifting heat sink 11 above.

[0033] In this embodiment, the sealing mechanism 9 includes a trapezoidal plate 22, a movable plate 21, and a sealing plate 26. The side of the trapezoidal plate 22 is integrally formed with the movable plate 21. The top and bottom of the movable plate 21 are welded with extension plates 23. The side of the extension plate 23 is welded with a first spring 24. The side of the heat dissipation frame 8 is provided with an inner through hole 31, and the surface of the air inlet channel 2 and the air outlet channel 3 is provided with an outer through hole 36. The surface of the movable plate 21 is inserted with a linkage column 25, and the end of the linkage column 25 is welded with a sealing plate 26. The other end of the first spring 24 is fixed to the surface of the heat dissipation frame 8. The trapezoidal plate 22 penetrates from the inside of the inner through hole 31 to the inside of the heat dissipation frame 8. The grooves 19, the inner through hole 31, the outer through hole 36, the trapezoidal plate 22, and the sealing plate 26 on both sides of the battery cell assembly 7 are all on the same horizontal plane. The size of the sealing plate 26 is the same as that of the outer through hole 36. The interior of the energy storage box 1 is divided into multiple independent power supply interlayers 4, and a support structure is installed through the independent power supply interlayer 4 to provide support for the battery cell assembly 7. The closing mechanism 9 cooperates with the pushing mechanism 17 at the rear end, and can automatically seal the heat dissipation through-holes on both sides of the independent power supply interlayer 4 when the battery cell assembly 7 is pulled out from the inside of the support mechanism 6, so that the air inlet channel 2 will not transport the low-temperature airflow into the independent power supply interlayer 4, and only provide heat dissipation treatment for the area where the battery cell assembly 7 is inserted, thereby improving the utilization rate of the heat dissipation system.

[0034] Specifically, when the battery cell assembly 7 is not inserted, the pushing mechanism 17 will be extended to press on the trapezoidal plate 22, so that the trapezoidal plate 22 is pushed toward the outside until the surface of the trapezoidal plate 22 is aligned with the inner wall of the heat dissipation frame 8. At this time, the first spring 24 is in a stretched state, and the sealing plate 26 at the end is embedded in the outer through hole 36. After closing the outer through hole 36, the low-temperature airflow on the inner wall of the air intake channel 2 can be prevented from passing through the outer through hole 36 and entering the outer heat dissipation chamber of the support mechanism 6. When the battery cell assembly 7 is inserted, the pushing mechanism 17 will be moved backward, and the two sides of the battery cell assembly 7 are mounted on the outside of the trapezoidal plate 22 through the grooves 19, so the force pushing the trapezoidal plate 22 toward the outside will not continue to be applied. Therefore, under the pulling effect of the first spring 24, the entire closing mechanism 9 will be moved toward the inside of the independent power supply interlayer 4, and finally the sealing plate 26 at the edge will be removed from the external through hole 36. Therefore, the air inlet channel 2 and the outer cavity of the support mechanism 6 are connected, and the low-temperature airflow enters the outer cavity of the support mechanism 6, passes through the connecting port 10, and passes through each lifting heat sink 11 and the fixed heat sink 12, taking away the heat generated on the heat sink, thereby achieving the heat dissipation effect.

[0035] In this embodiment, the pushing mechanism 17 includes a rear push plate 27, a second spring 28, and a scraper rod 29. The rear end of the heat dissipation frame 8 is screwed with a telescopic channel 16. One end of the second spring 28 is welded inside the telescopic channel 16, and the other end of the second spring 28 is welded to the surface of the rear push plate 27. The two ends of the rear push plate 27 are integrally formed with a scraper rod 29, and the top of the scraper rod 29 is integrally formed with a push ramp 30. The rear end of the lifting heat conducting plate 14 is integrally formed with a pressure-bearing inclined plate 20. The push ramp 30 is used to lean against the inclined surface of the pressure-bearing inclined plate 20. The inner sides of the lifting heat conducting plate 14 and the fixed heat conducting plate 13 are both mounted with thermal conductive silicone pads. In each supporting mechanism 6, a movable heat conducting plate structure is provided at the top. As the battery cell assembly 7 is inserted, there will be no direct sliding friction contact with the surface of the lifting heat conducting plate 14 and the fixed heat conducting plate 13 during the insertion process. This ensures that even if the battery cell assembly 7 is frequently plugged in and out, it will not cause wear on the surface of the battery cell assembly 7 or the silicon pad mounted on the surface of the heat conducting plate, thereby ensuring sufficient heat dissipation stability during subsequent long-term operation.

[0036] Specifically, the pushing mechanism 17 can push the rear push plate 27 at the front end toward the front end through the stretching effect of the second spring 28 at the rear end, and then cooperate with the scraping rods 29 at both ends to move along the inner wall of the heat dissipation frame 8, and can lean against the edge of the trapezoidal plate 22, thereby achieving the above-mentioned effect of triggering the closing mechanism 9. The top pushing inclined plate 30 cooperates with the pressure-bearing inclined plate 20 at the rear end of the lifting heat conducting plate 14, so that the lifting heat conducting plate 14 can move up and down as a whole, and finally achieves the purpose of the pushing mechanism 17 linking the top lifting heat conducting plate 14 to perform lifting and lowering movements.

[0037] The basic principles, main features and advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0038] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
