Description

Technical Field

[0001] This utility model belongs to the field of smart microgrid energy storage technology, and specifically relates to an integrated photovoltaic and energy storage smart microgrid system. Background Technology

[0002] A photovoltaic energy storage smart microgrid is a small-scale power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc. It is a local power supply network that can operate independently or in coordination with the main power grid. The integrated photovoltaic energy storage smart microgrid system integrates solar photovoltaic power generation, energy storage system and microgrid technology to provide users with green energy supply and help the zero-carbon transition.

[0003] In traditional photovoltaic-storage smart microgrid energy storage devices, the heat dissipation device design mostly adopts air cooling. Although air cooling can achieve heat dissipation to a certain extent, it has certain shortcomings. For example, the fan and energy storage components are relatively fixed in position, making it difficult to disassemble and install. At the same time, the fan can easily carry the heat of the energy storage components to the energy storage cabinet, causing the temperature in the energy storage cabinet to rise and affecting other electronic components. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated system of photovoltaic and energy storage smart microgrids.

[0005] To achieve the above objectives, this utility model provides an integrated photovoltaic-storage smart microgrid system, including a microgrid system. The microgrid system comprises a small power generation and distribution system consisting of distributed power sources, energy storage devices, energy conversion devices, and monitoring and protection devices, which is a local power supply network capable of operating independently or in coordination with the main power grid.

[0006] The energy storage device includes an energy storage cabinet, with a cabinet door hinged to the outer wall of the cabinet. An air outlet is provided on the outer wall of the cabinet door. A base is fixedly connected to the bottom of the inner wall of the energy storage cabinet. A support platform with a slide rail system is fixedly connected to the top of the base. A closing installation assembly is provided on the top of the support platform. An energy storage component is provided inside the closing installation assembly.

[0007] The closing installation assembly is used to close and install the energy storage device, and a cooling component is provided inside the closing installation assembly.

[0008] In the above technical solution, the closing installation assembly further includes a first card and a second card and a box that are slidably connected to each other on the top of the support platform. The first card and the second card and the box are connected by a locking mechanism. The energy storage component is fixedly installed inside the first card and the box. The top of the first card and the box and the second card and the box are both hinged with a sealing plate. The top of the first card and the box and the second card and the box are both fixedly connected with an elastic band.

[0009] In the above technical solution, the cooling component further includes an exhaust component fixedly installed on one side of the outer wall of the first card and box, and an air inlet component fixedly installed on one side of the outer wall of the second card and box.

[0010] In the above technical solution, a pair of first upright plates are fixedly connected to one side of the outer wall of the sealing plate on the top of the first card and the box, and a pair of second upright plates are fixedly connected to one side of the outer wall of the sealing plate on the top of the second card and the box. Two buffer plates and spring pieces are cross-fixed to the opposite sides of the first upright plate and the second upright plate.

[0011] In the above technical solution, a locking plate is slidably connected to the outer wall of the first upright plate, and a friction-enhancing plate is fixedly connected to the other side of the outer wall of the second upright plate, with the locking plate and the friction-enhancing plate abutting against each other.

[0012] In the above technical solution, an electromagnet is fixedly installed on one side of the outer wall of the first card and box and the second card and box. A magnetic mating plate is fixedly connected to one side of the outer wall of the sealing plate. A power supply block is fixedly installed on the top of the sealing plate. An electrode ball is installed on one side of the power supply block located on the top of the second card and box. A slot is provided on one side of the other power supply block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] During use, the first and second cards are locked together, which protects the internal energy storage components from shock. After the first and second cards are pulled apart, there is enough space to disassemble or install the energy storage components. The exhaust and intake components generate airflow, which is concentrated in the enclosed space created by the first and second cards, resulting in good heat dissipation. At the same time, the exhaust air is guided by the exhaust component and discharged from the inside of the energy storage cabinet through the air outlet. During this process, the heat will not radiate to other electronic components inside the energy storage cabinet. After the first and second cards are locked together, the electrode ball is inserted into the slot. At this time, the two power supply blocks are energized, which in turn supplies power to the electromagnet. After the electromagnet is energized, it generates magnetic force and attracts the magnetic mating plate, thus preventing the sealing plate from being flipped. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-4 The photovoltaic-storage smart microgrid integrated system shown includes a microgrid system 23, which is a small power generation and distribution system composed of distributed power sources 24, energy storage devices 25, energy conversion devices 26, monitoring devices 27 and protection devices 28. It is a local power supply network that can operate independently or in coordination with the main power grid.

[0022] Energy storage device 25 includes an energy storage cabinet 1. A cabinet door 2 is hinged to the outer wall of the energy storage cabinet 1. An air outlet 3 is provided on the outer wall of the cabinet door 2. A base 4 is fixedly connected to the bottom of the inner wall of the energy storage cabinet 1. A support platform 5 equipped with a slide rail system is fixedly connected to the top of the base 4. A closing installation assembly is provided on the top of the support platform 5. An energy storage component 13 is disposed inside the closing installation assembly. The energy storage component 13 is closed and installed using the closing installation assembly. The closing installation assembly includes a first clip and a box 6 and a second clip and a box 7 that are slidably connected to each other on the top of the support platform 5. Box 6 and the second card and box 7 are connected by a locking mechanism, and the energy storage component 13 is fixedly installed inside the first card and box 6 and the second card and box 7 respectively. The top of the first card and box 6 and the second card and box 7 are both hinged with sealing plates 12, and the top of the first card and box 6 and the second card and box 7 are both fixedly connected with elastic bands 14. The locking mechanism of the first card and box 6 and the second card and box 7 can protect the internal energy storage component 13 from shock. After the first card and box 6 and the second card and box 7 are pulled apart, there is enough space to disassemble or install the energy storage component 13, which is highly practical.

[0023] The assembly includes a cooling component, which consists of an exhaust component 22 fixedly installed on one side of the outer wall of the first card and box 6, and an air inlet component 17 fixedly installed on one side of the outer wall of the second card and box 7. When the first card and box 6 and the second card and box 7 are assembled, the exhaust component 22 and the air inlet component 17 generate airflow. The airflow is concentrated and flows within the enclosed space formed by the first card and box 6 and the second card and box 7, resulting in good heat dissipation. At the same time, the exhaust air is guided by the exhaust component 22 and discharged from the interior of the energy storage cabinet 1 through the air outlet 3. During the process, the heat will not radiate to other electronic components inside the energy storage cabinet 1.

[0024] A pair of first upright plates 8 are fixedly connected to one side of the outer wall of the sealing plate 12 on the top of the first card and box 6. A pair of second upright plates 9 are fixedly connected to one side of the outer wall of the sealing plate 12 on the top of the second card and box 7. Two buffer plates 19 and spring pieces 18 are cross-fixed to the opposite sides of the first upright plates 8 and the second upright plates 9. When the first card and box 6 and the second card and box 7 are engaged, the second upright plates 9 and spring pieces 18 touch and buffer the impact force. This design can prevent the impact feedback when the first card and box 6 and the second card and box 7 are engaged from damaging the energy storage component 13.

[0025] A locking plate 11 is slidably connected to the outer wall of the first upright plate 8, and a friction-enhancing plate 10 is fixedly connected to the other side of the outer wall of the second upright plate 9. The locking plate 11 and the friction-enhancing plate 10 abut against each other. The locking plate 11 is moved so that it slides down along one side of the first upright plate 8. After contacting the friction-enhancing plate 10, the friction between the two can lock the first card and box 6 and the second card and box 7, preventing them from shifting.

[0026] Electromagnets 20 are fixedly installed on one side of the outer wall of the first card and box 6 and the second card and box 7. A magnetic mating plate 21 is fixedly connected to one side of the outer wall of the sealing plate 12. A power supply block 15 is fixedly installed on the top of the sealing plate 12. An electrode ball 16 is installed on one side of the power supply block 15 on the top of the second card and box 7. A slot is provided on one side of the other power supply block 15. After the first card and box 6 and the second card and box 7 are engaged, the electrode ball 16 is inserted into the slot. At this time, the two power supply blocks 15 are energized, which in turn supplies power to the electromagnets 20. After the electromagnets 20 are energized, they generate magnetic force and attract the magnetic mating plate 21, thereby preventing the sealing plate 12 from being flipped.

[0027] Working principle:

[0028] In use, the first card and box 6 and the second card and box 7 are locked together, which can protect the internal energy storage component 13 from shock. After the first card and box 6 and the second card and box 7 are pulled apart, there is enough space to disassemble or install the energy storage component 13. The exhaust component 22 and the air intake component 17 generate wind energy. The wind force is concentrated in the closed space formed by the first card and box 6 and the second card and box 7, resulting in good heat dissipation. At the same time, the exhaust air is guided by the exhaust component 22 and discharged from the interior of the energy storage cabinet 1 through the air outlet 3. During the process, the heat will not radiate to other electronic components inside the energy storage cabinet 1. After the first card and box 6 and the second card and box 7 are locked together, the electrode ball 16 is inserted into the slot. At this time, the two power supply blocks 15 are energized, which in turn supplies power to the electromagnet 20. After the electromagnet 20 is energized, it generates magnetic force and attracts the magnetic mating plate 21, thereby preventing the sealing plate 12 from being flipped.
