Description

Technical Field

[0002] As the world pays more and more attention to renewable energy, photovoltaic power generation, as a clean and renewable energy form, is expanding its application scope. As an important part of the photovoltaic power generation system, photovoltaic energy storage cabinets are not only responsible for storing the electricity converted from solar energy, but also undertake the key task of supplying power to the load during grid failure or peak demand. However, with the rapid development and widespread application of photovoltaic energy storage technology, the operation stability and efficiency of photovoltaic energy storage cabinets have become increasingly prominent.

[0003] First, a large number of battery packs and power electronic devices are integrated inside the photovoltaic energy storage cabinet, and these components will generate a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, the temperature inside the cabinet will rise, which will not only affect the performance and service life of the battery pack, but may also cause safety accidents. Traditional heat dissipation designs often use fixed heat dissipation ports, which cannot flexibly adjust the heat dissipation efficiency according to factors such as ambient temperature and load status, and are difficult to meet the needs of complex and changing operating environments.

[0004] Secondly, photovoltaic energy storage cabinets are usually deployed in outdoor environments, and their air inlets and heat dissipation ports are exposed to the air for a long time, which easily absorbs impurities such as dust and sand. These impurities will gradually accumulate in the heat dissipation ports and air ducts during ventilation, forming blockages, seriously affecting ventilation efficiency, and further exacerbating the problem of temperature rise inside the cabinet.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0041] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0042] Please see attached Figure 1-Figure 11 As shown, this embodiment provides a photovoltaic energy storage cabinet, including a main component 10, the main component 10 includes a cabinet component 11, a cold air component 12 is fixedly connected to the left side of the inner cavity of the cabinet component 11, a storage component 13 is fixedly connected to the middle of the inner cavity of the cabinet component 11, and a self-cleaning component 14 is arranged on the top of the cabinet component 11;

[0043] A grille assembly 20, the grille assembly 20 is arranged on the left and right sides of the cabinet assembly 11;

[0044] Among them, after the battery for energy storage is installed in the storage component 13, the cabinet component 11 is operated to ventilate and cool the interior, and the cold air component 12 is used to reduce the temperature in the cabinet;

[0045] When the cabinet assembly 11 is ventilated, the self-cleaning assembly 14 is driven to operate, and the self-cleaning assembly 14 is adjusted to rotate along the top of the cabinet assembly 11 and clean;

[0046] The grille assembly 20 is divided into two states. In the initial state, the grille assembly 20 closes the cabinet assembly 11;

[0047] When the temperature in the cabinet is too high, the grille assembly 20 switches to the second state. In this state, the grille assembly 20 is driven to open, and the left and right sides of the cabinet assembly 11 are opened.

[0048] In this embodiment, after the energy storage battery is installed in the storage component 13, the ventilation component in the cabinet component 11 starts to operate, and the flow direction of the wind in the cabinet is adjusted by the storage component 13, so that the air passing through can fully contact the energy storage battery, thereby improving the heat dissipation effect. At the same time, the negative ion functional component in the cabinet component 11 will emit negative ions, which enter the cabinet through the airflow and contact the energy storage battery, effectively reducing the generation of static electricity, and further protecting the safe and stable operation of the energy storage battery. When the temperature is too high, the cold air component 12 sends low-temperature air into the cabinet component 11, and then the cold air is fully contacted with the energy storage battery through the ventilation component in the cabinet component 11, further reducing the temperature in the cabinet, and ensuring that the energy storage battery works under a suitable temperature environment. When the ventilation component in the cabinet component 11 is in operation, it will drive the self-cleaning component 14 to operate on the top of the cabinet component 11, and wipe the filter part on the top of the cabinet component 11 clean during operation to avoid affecting the ventilation effect. In the initial state, the grille component 20 closes the left and right sides of the cabinet component 11 to prevent external dust and impurities from entering. When the temperature in the cabinet is too high, the driving part of the grille assembly 20 starts to operate, opening the ventilation parts on the left and right sides of the cabinet assembly 11, increasing the ventilation volume of the cabinet assembly 11 and reducing the temperature in the cabinet. At the same time, by controlling the rotation angle of the main part of the grille assembly 20, the size of the opening of the ventilation part can be adjusted.

[0049] Next, please refer to Figure 1-Figure 5 The cabinet assembly 11 includes a cabinet 111, a cabinet door 112 is rotatably connected to the front of the cabinet 111, an air inlet 113 and an air outlet 114 are respectively provided at the top and bottom of the cabinet 111, a filter 115 is fixedly connected to the air inlet 113 and the air outlet 114 located outside the cabinet 111, a first motor 116 is fixedly connected to the air inlet 113 and the air outlet 114, a fan blade 117 is fixedly connected to the output shaft of the first motor 116, a negative ion generator 118 is fixedly connected to the top of the inner cavity of the cabinet 111, and the negative ion generator 118 is electrically connected to a generating head 119, and the generating head 119 is arranged below the fan blade 117 located in the air inlet 113;

[0050] The cold air assembly 12 includes an air cooler 121 fixedly connected to the bottom left side of the cabinet 111. The outlet of the air cooler 121 is connected to an air duct 122, which is pre-buried in the inner wall of the cabinet 111. The top of the air duct 122 is connected to an annular tube 123, and the inner circle of the annular tube 123 is evenly provided with exhaust nozzles 124. The annular tube 123 is arranged below the fan blades 117 located in the air inlet 113.

[0051] It should be noted that brackets are provided inside the air inlet 113 and the air outlet 114, and the first motor 116 is installed through the brackets. At the same time, the generating head 119 is also provided below the bracket inside the air inlet 113, so that the negative ions emitted by the generating head 119 can fully contact with the energy storage battery in the cabinet through the air entering through the air inlet 113;

[0052] A temperature sensor (not shown in the figure) is installed inside the cabinet 111 to detect the temperature inside the cabinet and adjust the heat dissipation solution of the energy storage cabinet according to the change of the temperature inside the cabinet.

[0053] In this embodiment, after the energy storage battery is installed in the cabinet, the first motor 116 is started, the fan blades 117 rotate to generate wind, and fresh air is introduced into the cabinet 111 from the air inlet 113. The fresh air first mixes with the negative ions generated by the generator 119 at the air inlet 113, and then enters the cabinet 111, fully contacts the energy storage battery, takes away the heat generated by the energy storage battery, and is discharged out of the cabinet through the air outlet 114. Such a design not only ensures the ventilation effect in the cabinet, but also effectively reduces the generation of static electricity through negative ions, further protecting the safe and stable operation of the energy storage battery. When the temperature in the cabinet exceeds the preset value, the cold air component 12 starts to work. The air cooler 121 starts, and the low-temperature air is sent into the annular tube 123 through the air duct 122. The exhaust nozzle 124 in the annular tube 123 blows out the cold air evenly, and mixes with the fresh air entering the air inlet 113, further reducing the temperature in the cabinet. Such a design ensures that the energy storage battery works in a suitable temperature environment and extends the service life of the energy storage battery.

[0054] Next, please refer to Figure 2-Figure 4 The storage assembly 13 includes a placement rack 131 fixedly connected to the inner cavity of the cabinet 111, a partition 132 is fixedly connected to the middle of the placement rack 131, an air duct 133 is opened between the upper and lower adjacent placement racks 131, and an air guide plate 134 is fixedly connected to the top and rear side of the inner cavity of the cabinet 111. An air outlet 135 is opened in the middle of the air guide plate 134 at the position of the air duct 133, and the top of the air guide plate 134 is arranged below the air inlet 113;

[0055] Through slots are provided on both upper and lower sides of the placement rack 131 , and a gap is reserved between the front of the placement rack 131 and the cabinet door 112 , and the bottom of the gap is connected to the air outlet 114 .

[0056] It should be noted that a plurality of groups of placement rods are evenly arranged at the bottom of the cabinet 111, so that larger electrical components can be installed at the bottom of the inner cavity of the cabinet 111;

[0057] At the same time, the gap between the front of the placement rack 131 and the cabinet door 112 is connected to the area above the placement rod, so that the circulating air can contact the electrical components on the placement rod, thereby improving air utilization.

[0058] In this embodiment, the air entering the cabinet 111 through the air inlet 113 will be evenly discharged from the air outlet 135 through the guidance of the air guide plate 134, flow along the air duct 133, and pass through the gap between the upper and lower adjacent placement racks 131 to fully contact the energy storage battery. Due to the design of the air guide plate 134, the air can be evenly distributed in the cabinet 111, ensuring that each energy storage battery can obtain a good heat dissipation effect. At the same time, the through grooves on the upper and lower sides of the placement rack 131 and the gap between it and the cabinet door 112 make the air flow in the cabinet smoother, further improving the heat dissipation efficiency.

[0059] Next, please refer to Figure 7-Figure 9 The self-cleaning component 14 includes a canopy 141 fixedly connected to the top of the cabinet 111, a protective shell 142 is fixedly connected to the bottom of the canopy 141, a rotating shaft 143 is fixedly connected to the top of the fan blade 117 located in the air inlet 113, the top of the rotating shaft 143 passes through the protective shell 142 and is rotatably connected to the top of the canopy 141, a rotating ring 144 is rotatably connected to the top of the inner cavity of the canopy 141, and a tooth groove 145 is provided on the top inner ring of the rotating ring 144, and a gear 146 is rotatably connected to the top of the inner cavity of the canopy 141, and the outer ring of the gear 146 is meshed in the tooth groove 145, and the top outer ring of the gear 146 is meshed in the tooth groove 145. The ring is provided with a groove, and a driving crawler 147 is rollingly connected in the groove. The top outer ring of the rotating shaft 143 is also provided with a groove, and the left end of the driving crawler 147 is rollingly connected in the groove at the top of the rotating shaft 143. The bottom of the rotating ring 144 is tubular, and the bottom inner ring of the rotating ring 144 is movably sleeved on the outer ring of the rotating shaft 143. The bottom outer ring of the rotating ring 144 is rotatably connected to the bottom of the protective shell 142. The outer ring of the bottom of the rotating ring 144 extending out of the protective shell 142 is fixedly connected to a scraper 148, and the inner ring of the scraper 148 is fixedly connected to a brush plate 149, and the brush plate 149 is contact-connected to the outer ring of the filter screen 115.

[0060] The width of the awning 141 is greater than the width of the cabinet 111, and the awning 141 is connected to the cabinet 111 through four connecting bolts, so that rainwater can fall on the outside of the cabinet 111 through the awning 141, and the connection method of the connecting bolts can make the awning 141 easy to disassemble.

[0061] It should be noted that the portion where the rotating ring 144 contacts the protective shell 142 is provided with a bearing (not shown in the figure) to improve the smoothness of the rotation of the rotating ring 144 and the protective shell 142 and avoid excessive friction that reduces the service life of the device.

[0062] The scraper 148 and the brush plate 149 are made of wear-resistant and soft materials, which can effectively clean the filter screen 115 without causing damage to the filter screen 115, thereby ensuring the long-term stable operation of the equipment.

[0063] In this embodiment, when the fan blade 117 is running, it will drive the rotating shaft 143 to rotate, and then drive the left end of the transmission crawler 147 to roll in the groove at the top of the rotating shaft 143. Since the right end of the transmission crawler 147 is connected to the outer ring groove of the gear 146, and the gear 146 is meshed with the tooth groove 145 of the inner ring of the rotating ring 144, when the transmission crawler 147 moves, it will drive the gear 146 to rotate, and then drive the rotating ring 144 to rotate. The scraper 148 and the brush plate 149 at the bottom of the rotating ring 144 rotate accordingly, contact and scrape the outer ring of the filter 115, effectively remove the dust and debris accumulated on the filter 115, and keep the filter 115 clean and unobstructed.

[0064] In addition, the design of the canopy 141 can not only provide effective rain protection for the energy storage cabinet, but also block direct sunlight, reduce the temperature inside the cabinet, and further improve the service life and safety of the energy storage battery.

[0065] Please refer again Figure 10-11 The grille assembly 20 includes an air vent 21 opened on the left and right sides of the cabinet 111, and the inner cavity of the air vent 21 is evenly arranged with grid plates 22 above and below. The grid plates 22 are all rotatably connected to the inner cavity of the air vent 21, and connecting ropes 23 are fixedly connected between adjacent grid plates 22. A double-axis motor 24 is fixedly connected to the inner cavity of the cabinet 111 below the air vent 21, and a rotating rod 25 is fixedly connected to the output shafts at both ends of the double-axis motor 24. The top of the rotating rod 25 is fixedly connected to a wire roller 26, and the inner circle of the wire roller 26 is fixedly connected to a pull rope 27. The top of the pull rope 27 extends into the air vent 21 and is fixedly connected to the bottom of the lowest grid plate 22. The cabinet 111 is rotatably connected to a roller 28 at the position below the air vent 21, and the middle outer circle of the pull rope 27 is rollingly connected to the inner circle of the roller 28;

[0066] The bottom of the grid plate 22 is provided with a rubber sealing strip, and the top outer ring of the grid plate 22 is also provided with a rubber sleeve.

[0067] It should be noted that a slope is provided on the outer side of the bottom of the air vent 21 so that rainwater can be discharged along the slope on rainy days to avoid rainwater accumulation.

[0068] In this embodiment, when the dual-axis motor 24 is started, the output shafts at both ends thereof will drive the rotating rod 25 to rotate synchronously, thereby driving the line roller 26 to rotate, and then pulling the pull rope 27 downward. Since the top of the pull rope 27 is fixed below the lowest grid plate 22, when the pull rope 27 moves downward, it will drive the lowest grid plate 22 to rotate clockwise, and through the transmission of the connecting rope 23, all the grid plates 22 above will rotate synchronously. As the grid plate 22 rotates, the originally closed air vent 21 will gradually open, allowing external air to enter the cabinet 111 for ventilation and heat dissipation. When the air vent 21 needs to be closed, it is only necessary to reversely start the dual-axis motor 24 to make the rotating rod 25 and the line roller 26 rotate in the opposite direction, and the pull rope 27 will gradually relax. Under the action of its own gravity and external air pressure, the grid plate 22 will rotate counterclockwise to the initial position, and the air vent 21 will be completely closed.

[0069] In addition, the rubber sealing strip at the bottom of the grille 22 and the rubber cover at the top can not only effectively prevent external impurities such as rainwater and dust from entering the interior of the cabinet 111, but also provide a certain buffering and sealing effect when the grille 22 rotates, thereby ensuring the air quality and safety in the cabinet.

[0070] The working principle of the present invention is as follows: the energy storage battery is placed in the placement rack 131, and then the first motor 116 is started, the fan blades 117 rotate to generate wind, and fresh air is introduced into the cabinet 111 from the air inlet 113. The fresh air is first mixed with the negative ions generated by the generator 119 at the air inlet 113, and then enters the cabinet 111. The air entering the cabinet 111 through the air inlet 113 will be evenly discharged from the air outlet 135 through the guidance of the air guide plate 134, and flow along the air duct 133, and pass through the gap between the upper and lower adjacent placement racks 131, fully contact with the energy storage battery, take away the heat generated by the energy storage battery, and discharge it outside the cabinet through the air outlet 114. When the temperature inside the cabinet exceeds the preset value, the cold air component 12 starts to work. The air cooler 121 starts, and sends low-temperature air into the annular tube 123 through the air duct 122. The exhaust nozzle 124 in the annular tube 123 blows out the cold air evenly, and mixes it with the fresh air entering from the air inlet 113, further reducing the temperature in the cabinet. When the fan blade 117 is running, it will drive the rotating shaft 143 to rotate, and then drive the left end of the transmission crawler 147 to roll in the groove at the top of the rotating shaft 143. Since the right end of the transmission crawler 147 is connected to the outer ring groove of the gear 146, and the gear 146 is meshed with the tooth groove 145 of the inner ring of the rotating ring 144, when the transmission crawler 147 moves, it will drive the gear 146 to rotate, and then drive the rotating ring 144 to rotate. The scraper 148 and the brush plate 149 at the bottom of the rotating ring 144 rotate accordingly, contact and scrape the outer ring of the filter 115, effectively remove the dust and debris accumulated on the filter 115, and keep the filter 115 clean and unobstructed. When the dual-axis motor 24 is started, the output shafts at both ends thereof will drive the rotating rod 25 to rotate synchronously, thereby driving the line roller 26 to rotate, and then pulling the pull rope 27 downward. Since the top of the pull rope 27 is fixed below the lowest grid plate 22, when the pull rope 27 moves downward, it will drive the lowest grid plate 22 to rotate clockwise, and through the transmission of the connecting rope 23, all the grid plates 22 above will rotate synchronously. As the grid plate 22 rotates, the originally closed air vent 21 will gradually open, allowing external air to enter the interior of the cabinet 111 for ventilation and heat dissipation. When the air vent 21 needs to be closed, it is only necessary to reversely start the dual-axis motor 24 to make the rotating rod 25 and the line roller 26 rotate in the opposite direction, and the pull rope 27 will gradually relax. Under the action of its own gravity and external air pressure, the grid plate 22 will rotate counterclockwise to the initial position, and the air vent 21 will be completely closed.

[0071] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
