Description

Technical Field

[0001] The present invention relates to the technical field of energy storage devices, and in particular to a photovoltaic panel energy storage device. Background Art

[0002] Photovoltaic panel energy storage devices, also known as photovoltaic energy storage equipment, refer to devices that convert solar energy into electrical energy through solar panels (also known as photovoltaic components or photovoltaic modules) and store the electrical energy using energy storage systems (such as battery modules);

[0003] Photovoltaic energy storage container is a form of photovoltaic energy storage equipment, which uses photovoltaic panels to convert solar energy into electrical energy and stores it through an energy storage system, so that solar energy can continue to provide electricity even in rainy weather or at night. When the photovoltaic energy storage container is in use, first, the photovoltaic panel is installed on one side of the container to absorb solar energy and convert it into direct current. Then, the direct current is converted into alternating current through an inverter and transmitted to the energy storage system for storage. During the storage process, electricity can be converted into chemical energy, electrical energy, or mechanical energy, and different energy storage technologies are used to ensure the storage time and stability of the electricity. In addition, photovoltaic energy storage containers can also be combined with intelligent control systems to achieve flexible scheduling and allocation of energy, thereby effectively improving the utilization rate of solar energy;

[0004] At present, the battery energy storage system inside the existing solar energy storage container is particularly sensitive to temperature. Especially when the solar energy storage container is moved to different locations for use, the battery module will experience complex and changeable operating conditions during operation, sometimes charging and discharging at high rates, and sometimes charging and discharging at low rates. This causes uneven heat generation by the battery, further causing uneven temperature distribution inside the container, resulting in battery inconsistency, thereby affecting the performance and reliability of the entire system. To this end, we propose a photovoltaic panel energy storage device. Summary of the Invention

At the same time, a connecting mechanism can also be installed on the outside of the closing door 34, so that when the two closing doors 34 are closed at the opening of the container body 1, the connecting mechanism can ensure that the closing door 34 is tightly connected to the container body 1, and the connecting mechanism can be a latch;

[0047] At the same time, the second sealing door assembly 31 is an existing sealing door structure, and a sealed space is formed between the second sealing door assembly 31 and the baffle plate 2, which can ensure that multiple battery modules 23 are stably placed in the sealed space. At the same time, when the battery module 23 needs to be inspected or repaired, the sealing door structure can be opened;

[0048] See also Figures 3 to 6 The baffle plate 2 is located on one side of the multiple support plates 21 and is provided with a temperature uniform distribution mechanism 4, which is used to dissipate heat for the battery modules 23 on the multiple support plates 21, and the container body 1 is provided with an air inlet 11 corresponding to the temperature uniform distribution mechanism 4;

[0049] The temperature uniform distribution mechanism 4 includes an air inlet shell 41, an air guide 42, an air guide shell 43 and a temperature sensor 44. The air inlet shell 41 is fixedly located below the support plate 21 and is fixedly installed at the bottom of the container body 1. An air inlet 411 is provided on one side of the air inlet shell 41, and the air inlet shell 41 is connected to the air inlet 11 through the air inlet 411.

[0050] The air guide 42 is located inside the air inlet housing 41 and is used to guide the air flow at the air inlet 411;

[0051] Multiple air guide housings 43 are provided, and the multiple air guide housings 43 are equidistantly distributed on the top of the air inlet housing 41. The air guide housings 43 are connected to the air inlet housing 41. The multiple support plates 21 are respectively perpendicular to the multiple air guide housings 43. An installation space 45 is formed between the support plates 21 and the air guide housings 43. The battery module 23 is located in the installation space 45.

[0052] There are multiple temperature sensors 44, and the multiple temperature sensors 44 are respectively installed in the installation space 45;

The input end of the filter 421 is connected to the air inlet 411, and the output end of the filter 421 is connected to the input end of the cooling fan 422. The cooling fan 422 is used to guide the cooling air flow into the interior of the air inlet shell 41.

[0054] Specific implementation process: The photovoltaic panel energy storage device in this embodiment is moved to the required working position through the container, and then the filtered natural airflow is cooled by the operation of the filter 421 and the cooling fan 422, and the cooled airflow is introduced into the interior of the air intake shell 41. Subsequently, a large amount of cooling air inside the air intake shell 41 passes through the exhaust holes on the multiple air guide shells 43 and is discharged to the battery modules 23 in the installation space 45 respectively, so as to achieve the effect of sufficient cooling and heat dissipation of the battery modules 23. At the same time, the temperature sensor 44 located on the outside of the battery module 23 is used to monitor the temperature change of the battery module 23 in real time;

[0055] See also Figures 7 and 8 Ventilation holes 24 are provided on the baffle plate 2 at positions corresponding to the plurality of battery modules 23. In this embodiment, the battery modules 23 do not affect the flow of air at the vents 24. An airflow outlet mechanism 5 is installed at the vents 24.

[0056] The air flow outlet mechanism 5 includes a connecting pipe 51 and a solenoid valve 52. The connecting pipe 51 passes through the vent hole 24, and the solenoid valve 52 is installed at the end of the connecting pipe 51 away from the battery module 23.

[0057] Specific implementation process: In this embodiment, although connecting pipes 51 are provided at positions corresponding to the plurality of vent holes 24, when the temperature between the plurality of battery modules 23 is relatively stable, the solenoid valve 52 at the connecting pipe 51 near the center of the baffle plate 2 is opened, and air is discharged through the connecting pipe 51;

[0058] When the temperature of the battery module 23 is too high, the corresponding temperature sensor 44 sends a signal to the controller, and the solenoid valve 52 at the center of the baffle plate 2 is closed, while the solenoid valves 52 at the multiple connecting pipes 51 near the location where the temperature is too high are opened. That is, the solenoid valves 52 at the multiple connecting pipes 51 surrounding the high-temperature battery module 23 are all opened, so that a large amount of air flows through the battery module 23 at the high-temperature location, achieving the effect of quickly dissipating heat and cooling the battery module 23, further ensuring the stability of the operation of the battery module 23.

[0059] See also Figures 1 to 3, multiple photovoltaic panel bodies 22 are hinged to each other by hinges, and when the photovoltaic bodies are in use, they can be unfolded relative to each other, and the unfolded multiple photovoltaic panel bodies 22 are supported by the brackets, and when the photovoltaic panel bodies 22 are moved to the inside of the container body 1, they are folded relative to each other and placed inside the container body 1. At the same time, a fixing mechanism can be provided inside the container body 1 for fixing the folded multiple photovoltaic panel bodies 22. In this embodiment, the fixing mechanism is preferably a fixed chassis, and then after the multiple photovoltaic panel bodies 22 are folded relative to each other, gaps are left between the folded photovoltaic panel bodies 22, so that the multiple columns of dust removal holes on the first exhaust member 63 correspond to the gaps, thereby achieving the function of dust removal for the folded photovoltaic panel bodies 22;

[0060] An air outlet 12 is provided at the bottom of the container body 1 and at a side away from the air inlet 11 . The air inlet 11 and the air outlet 12 are respectively arranged on both sides of the baffle plate 2 .

[0061] Filter plates 13 are detachably installed at the air inlet 11 and the air outlet 12;

[0062] See also Figures 6 and 7 as well as Figures 11 to 15 , multiple airflow outlet mechanisms 5 are located on the other side of the baffle plate 2 and are provided with an airflow conversion mechanism 6, which is used to convert the derived airflow, and when the multiple photovoltaic panel bodies 22 move to the outside of the container body 1, the airflow conversion mechanism 6 forms an air curtain at the opening on one side of the container body 1. When the multiple photovoltaic panel bodies 22 are stacked inside the container body 1, the airflow conversion mechanism 6 removes dust on the surface of the photovoltaic panels;

[0063] The airflow conversion mechanism 6 includes a transfer shell 61, a transfer tube 62, a first exhaust member 63, a second exhaust member 64, a conversion tube 65, and a conversion member 7. The transfer shell 61 is fixedly mounted on the side of the baffle plate 2 away from the battery module 23 and is sleeved on the outside of the multiple connecting tubes 51. An airflow channel is formed between the transfer shell 61 and the baffle plate 2.

[0064] One end of the transfer pipe 62 is connected to the transfer shell 61. The first exhaust member 63 is located on one side of the interior of the container body 1 and is connected to the transfer pipe 62.

[0065] A first conversion hole 651 is provided at a position where the conversion tube 65 moves to the first exhaust member 63 , and a second conversion hole 652 is provided at a position where the conversion tube 65 moves to the second exhaust member 64 .

[0066] The first exhaust member 63 includes an exhaust pipe 631 and an exhaust shell 632. One end of the exhaust pipe 631 is connected to the transfer pipe 62, and the other end of the exhaust pipe 631 is connected to the exhaust shell 632. When the transfer pipe 62 moves to the position of the exhaust pipe 631, it is connected to the exhaust pipe 631 through the first conversion hole 651.

[0067] The exhaust shell 632 is fixedly installed on the inner side of the container body 1, and a plurality of rows of dust removal holes are equidistantly provided on one side of the exhaust shell 632 close to the photovoltaic panel body 22.

[0068] The second exhaust component 64 includes a top pipe 641, an air curtain shell 642, and an air curtain cover 643. One end of the top pipe 641 is connected to the transfer pipe 62. When the conversion pipe 65 moves to the position of the top pipe 641, it is connected to the top pipe 641 through the second conversion hole 652. The top end of the top pipe 641 is connected to the air curtain shell 642. The air curtain shell 642 is fixedly installed at the top end of the interior of the container body 1 and is close to the opening of the container body 1.

[0069] A direct current port 6421 is provided at the bottom of the air curtain shell 642 . The air curtain cover 643 is located outside the direct current port 6421 , and the air curtain cover 643 is fixedly installed at the bottom of the air curtain shell 642 .

[0070] The conversion member 7 includes a fixed plate 71, a guide plate 72, a tooth block 73, a rotating gear 74, a guide frame 75 and a connecting spring 76. The fixed plate 71 is fixedly mounted on one end of the conversion tube 65 located on the outside of the transfer tube 62. The guide plate 72 is fixedly mounted on the fixed plate 71. There are multiple tooth blocks 73, and multiple tooth blocks 73 are equidistantly mounted on one side of the guide plate 72. The rotating gear 74 is meshed and connected with the tooth block 73, and the rotating gear 74 is fixedly sleeved on the outside of one of the rotating shafts 32. A moving opening is provided on the guide plate 72. The guide frame 75 is U-shaped. The guide frame 75 slides through the moving opening, and both ends of the guide frame 75 are fixedly connected to the inner side of the container body 1. One end of the connecting spring 76 is fixedly connected to the guide frame 75, and the other end of the connecting spring 76 is fixedly mounted inside the moving opening.

[0071] Specific implementation process: When the closing door 34 opened on one side of the container body 1 is in a closed state, then at this time, the multiple photovoltaic panel bodies 22 are relatively folded and placed inside the container body 1, such as Figures 9 and 10, and the folded multiple photovoltaic panel bodies 22 are located on one side of the blocking plate. At this time, under the connection action of the conversion member 7, the first conversion hole 651 on the conversion tube 65 is connected to the exhaust pipe 631, and the second conversion hole 652 on the conversion tube 65 deviates from the top tube 641. At this time, the airflow after dissipating heat to the multiple battery modules 23 enters the transfer tube 62 through the transfer shell 61, and finally enters the exhaust pipe 631 through the first conversion hole 651 of the conversion tube 65, and enters the exhaust shell 632 through the exhaust pipe 631. The multiple rows of dust removal holes on the exhaust shell 632 correspond to the surface of the folded photovoltaic panel body 22, so that the exhausted airflow flows through the surface of the photovoltaic panel body 22 and then flows out through the air outlet 12. The airflow flowing through the surface of the photovoltaic panel body 22 also plays a role in removing dust on the surface of the photovoltaic panel, further facilitating the subsequent use of the photovoltaic panel body 22.

[0072] When the two closing doors 34 at the opening on one side of the container body 1 are opened, the rotating gear 74 rotates relative to the multiple tooth blocks 73. Due to the limiting effect of the multiple tooth blocks 73 on the guide plate 72, the guide plate 72 further drives the conversion tube 65 to move relative to the transfer tube 62 through the fixed plate 71 until the closing door 34 is fully opened. At this time, the first conversion hole 651 on the conversion tube 65 deviates from the exhaust pipe 631, and the second conversion hole 652 on the conversion tube 65 moves to the top tube 641. At this time, the exhaust pipe 631 is completely opened. The heated airflow passes through the transfer shell 61 and enters the transfer tube 62, and finally enters the top tube 641 through the first conversion hole 651 of the conversion tube 65, and flows out through the DC port 6421 at the bottom of the wind curtain shell 642. The outflowing airflow forms a wind curtain at the opening on one side of the container body 1 to prevent external dust from entering the interior of the container body 1. At this time, multiple photovoltaic panel bodies 22 extend from the opening of the container body 1 to the outside of the container body 1 through the bracket, which can convert light energy into electrical energy and store it in multiple battery modules 23. Example 2

[0073] See also Figures 14 and 15 , Example 2 is a further supplementary explanation of Example 1, specifically: a fixing frame 8 is installed on the top of the top pipe 641, and a rotating shaft 81 passes through the fixing frame 8, the rotating shaft 81 is rotatably connected to the fixing frame 8, a rotating fan 82 is installed at the bottom of the rotating shaft 81, and a first spur gear 83 is installed on the top of the rotating shaft 81, and a second spur gear 84 is meshed and connected to the outer side of the first spur gear 83, the second spur gear 84 is located inside the air curtain housing 642, and a support rod 85 is fixedly connected to one side of the second spur gear 84, a spiral blade 86 is fixedly sleeved on the outer side of the support rod 85, and one end of the support rod 85 is rotatably connected to the air curtain housing 642;

[0074] Therefore, when the air flow enters the air curtain shell 642 from the top pipe 641, the rotating fan 82 is synchronously rotated due to the flow of air flow, and the rotating shaft 81 is further rotated. When the rotating shaft 81 rotates, the second straight bevel gear 84 is driven to rotate through the first straight bevel gear 83, and the support rod 85 further drives the spiral blade 86 to rotate inside the air curtain shell 642. At this time, the air flow can be evenly distributed in the air curtain shell 642, and finally the DC port 6421 at the bottom of the air curtain shell 642 is evenly discharged, forming the effect of a uniform air curtain.
