A long-life photovoltaic energy storage device

Abstract

This application relates to the field of photovoltaic energy storage technology and discloses a long-life photovoltaic energy storage device. By setting up a recovery chamber, guide rails, and a power generation trolley, the power generation trolley exits the protective chamber during the day and travels along the guide rails to a specific location to receive solar energy and generate electricity. At night or in extreme conditions, it returns to the recovery chamber for protection. This avoids damage to the equipment from extreme conditions such as strong winds and sandstorms, and the higher temperature in the recovery chamber compared to the outside at night reduces discharge losses of the energy storage battery modules under low-temperature conditions. In this application, the two guide rails are semi-circular on the side facing away from the recovery chamber, and the bottom of the power generation trolley is equipped with two pairs of steering wheels, allowing the trolley to turn as it moves along the guide rails and passes through the semi-circular arc. Adjustment is achieved by controlling the final stopping position of the power generation trolley using blocking components, based on the different incident angles of the sun between the Tropic of Cancer and the Tropic of Capricorn. This adjustment is completed automatically during the movement of the power generation trolley and requires no additional operation.

Description

Technical Field

[0001] This application relates to the field of photovoltaic energy storage technology, specifically to a long-life photovoltaic energy storage device. Background Technology

[0002] Photovoltaics is a new type of power generation that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy.

[0003] The existing technology has the following problems:

[0004] 1. Most existing photovoltaic energy storage power generation devices are set up in a fixed manner. As the seasons change, the angle of the sun's incidence will change. In order to ensure the maximum efficiency of receiving solar energy, the angle of the photovoltaic panel needs to be manually adjusted so that the photovoltaic panel is as perpendicular as possible to the angle of the sun's incidence, which is a cumbersome operation.

[0005] 2. In existing technologies, the temperature is low at night, and the discharge of energy storage batteries at night will cause additional power loss, affecting the overall power generation efficiency.

[0006] 3. Outdoor photovoltaic power generation equipment is easily affected and damaged under extreme weather conditions. For example, organic photovoltaic panels, which are currently developing rapidly, have unparalleled power generation efficiency and relatively low manufacturing costs, but they are easily damaged under certain extreme weather conditions, which prevents them from being widely used. Utility Model Content

[0007] In view of the above problems, this application provides a long-life photovoltaic energy storage device that allows for convenient adjustment of the photovoltaic panel angle and avoids damage to the device caused by extreme weather.

[0008] According to one aspect of the embodiments of this application, a long-life photovoltaic energy storage device is provided. The long-life photovoltaic energy storage device includes a recovery chamber, with multiple protective chambers opened on one side of the recovery chamber. Each protective chamber has two guide rails on one side, the two guide rails forming a semi-circular arc on the side opposite to the recovery chamber. A generator trolley is mounted on the guide rails, and a blocking member for blocking the generator trolley is provided at the guide rails. The generator trolley includes a vehicle body, with a pair of drive wheels and two pairs of steering wheels sequentially arranged at the bottom of the vehicle body. The steering wheels are connected to the bottom of the vehicle body via a universal adjustment device. A drive device is provided at each drive wheel, and the drive device is electrically connected to a controller. A cavity is opened on one side of the vehicle body, and an inverter assembly and an energy storage battery assembly are arranged within the cavity. A solar photovoltaic panel is arranged on the top of the vehicle body, and the solar photovoltaic panel, the inverter assembly, and the energy storage battery assembly are sequentially connected.

[0009] In some embodiments, the drive device includes a drive shaft coaxially connected between the two drive wheels, a driven chain link sleeved on the drive shaft, a power compartment provided on one side of the vehicle body, a servo motor fixed in the power compartment, a drive chain link coaxially connected to the servo motor, and the drive chain link and the driven chain link being connected by chain drive.

[0010] In some embodiments, an angle adjustment device is provided at the solar photovoltaic panel. The angle adjustment device includes a rotating shaft fixed to the top of the vehicle body via a rotating seat and a slide rail provided at the top of the vehicle body. The rotating shaft passes through the edge plate on one side of the solar photovoltaic panel. A lifting shaft is hinged to the back side of the solar photovoltaic panel. A sliding block is hinged to the other end of the lifting shaft. The sliding block is slidably connected to the slide rail.

[0011] In some embodiments, the bottom of the sliding block is slidably connected to the slide rail via a sliding groove, a threaded rod is provided through one side of the sliding block, one side of the threaded rod passes through the book search sliding groove and abuts against the slide rail, and a rotating ring is coaxially connected to the other end of the threaded rod.

[0012] In some embodiments, the vehicle body is provided with a plurality of heat dissipation components, which are connected to the cavity.

[0013] In some embodiments, a plug assembly is provided at the rear end of the vehicle body, the plug assembly is electrically connected to the energy storage battery assembly, and a socket assembly matching the plug assembly is provided in the protective cavity.

[0014] In some embodiments, the guide rail is made of iron, and the blocking element is a magnet.

[0015] The beneficial effects of this application are as follows: By setting up a recovery chamber, guide rails, and a power generation trolley in coordination, the power generation trolley exits the protective chamber during the day and moves along the guide rails to a specific position to receive solar energy and generate electricity. At night or in extreme situations, it returns to the recovery chamber for protection. This avoids damage to the equipment from extreme conditions such as strong winds and sandstorms. Furthermore, the recovery chamber has a higher temperature than the outdoor nighttime temperature, which can reduce the discharge loss of the energy storage battery components under low-temperature conditions. In this application, the two guide rails are semi-circular on the side facing away from the recovery chamber, and the bottom of the power generation trolley is equipped with two pairs of steering wheels. This allows the trolley to turn as it moves along the guide rails and passes through the semi-circular arc. Adjustment is achieved by controlling the final stopping position of the power generation trolley using a blocking component, based on the different incident angles of the sun between the Tropic of Cancer and the Tropic of Capricorn. This adjustment is completed automatically during the movement of the power generation trolley and requires no additional operation.

Figure 5 Provided for the embodiments of this application Figure 2Enlarged view at point A. The high-lifespan photovoltaic energy storage device 1000 includes a recovery chamber 200, which is used to retrieve and protect the generator trolley 100 at night and in extreme weather conditions. Its relatively enclosed design effectively maintains the temperature. Multiple protective chambers 210 are provided on one side of the recovery chamber 200, each corresponding to one generator trolley 100. The size of the protective chambers 210 can be adjusted according to the size of the generator trolley 100. Two guide rails 300 are provided on one side of each protective chamber 210. The side of the two guide rails 300 facing away from the recovery chamber 200 is semi-circular. The generator trolley 100 can travel along the guide rails 300 and turn at the semi-circular end of the guide rails 300, thereby changing the angle of its top solar photovoltaic panel 170. A power generation trolley 100 is mounted on a guide rail 300. A blocking element 310 is installed on the guide rail 300 to prevent the power generation trolley 100 from continuing to move. The blocking element 310 can be a magnet. The operator sets the position of the blocking element 310 according to the different incident angles of the sun between the Tropic of Cancer and the Tropic of Capricorn, so that the trolley stops accurately in the relative position, at which point the angle of the solar photovoltaic panel 170 will be at its optimal state. The power generation trolley 100 includes a trolley body 110, which carries other components and can be welded from a steel frame. The bottom of the vehicle body 110 is provided with a pair of drive wheels 120 and two pairs of steering wheels 130. The steering wheels 130 are connected to the bottom of the vehicle body 110 via a universal adjustment device. A drive device 140 is provided at the drive wheels 120 to drive the drive wheels 120 to rotate. The steering wheels 130 are used for positioning and steering to prevent the drive wheels 120 from slipping off the track during the movement of the vehicle body 110. The drive device 140 is electrically connected to a controller, which is used to control the opening and closing of the drive device 140 and the driving direction of the drive device 140. A cavity 111 is opened on one side of the vehicle body 110. An inverter assembly 150 and an energy storage battery assembly 160 are arranged in the cavity 111. A solar photovoltaic panel 170 is arranged on the top of the vehicle body 110. The solar photovoltaic panel 170, the inverter assembly 150, and the energy storage battery assembly 160 are connected in sequence.

[0027] As can be seen from the above, in this embodiment, by setting up a recovery chamber 200, a guide rail 300, and a power generation trolley 100 in cooperation, the power generation trolley 100 exits the protective chamber 210 during the day and moves along the guide rail 300 to a specific position to receive solar energy and generate electricity. At night or in extreme situations, it returns to the recovery chamber 200 for protection. On the one hand, this avoids damage to the equipment from extreme conditions such as strong winds and sandstorms. On the other hand, the temperature in the recovery chamber 200 is relatively higher than the outdoor nighttime temperature, which can reduce the discharge loss of the energy storage battery module 160 under low-temperature conditions. In this embodiment, the two guide rails 300 are semi-circular on the side away from the recovery chamber 200, and the bottom of the power generation trolley 100 is provided with two pairs of steering wheels 130, so that the trolley can turn when moving along the guide rail 300 and passing through the semi-circular arc. According to the different incident angles of the sun between the Tropic of Cancer and the Tropic of Capricorn, the final stopping position of the power generation trolley 100 can be adjusted by controlling the blocking member 310. This adjustment is completed automatically during the movement of the power generation trolley 100 without additional operation.

[0028] In some embodiments, the drive device 140 includes a drive shaft 141 coaxially connected between two drive wheels 120, a driven chain link 142 sleeved on the drive shaft 141, a power compartment 112 provided on one side of the vehicle body 110, a servo motor 143 fixed inside the power compartment 112, a drive chain link 144 coaxially connected to the servo motor 143, and the drive chain link 144 and the driven chain link 142 are connected by a chain 145. In this embodiment, a specific configuration of the drive device 140 is shown. During operation, after the servo motor 143 is turned on, it sequentially drives the drive chain link 144, the chain 145, the driven chain link 142, and the drive shaft 141 to rotate, and then the drive shaft 141 further drives the two drive wheels 120 to rotate. When the servo motor 143 reverses, the travel path of the generator trolley 100 will be reversed.

[0029] In some embodiments, an angle adjustment device 180 is provided at the solar photovoltaic panel 170. The angle adjustment device 180 includes a rotating shaft 182 fixed to the top of the vehicle body 110 via a rotating seat 181 and a slide rail 183 disposed on the top of the vehicle body 110. The rotating shaft 182 passes through the edge of one side of the solar photovoltaic panel 170. A lifting shaft 184 is hinged to the back side of the solar photovoltaic panel 170, and a sliding block 185 is hinged to the other end of the lifting shaft 184. The sliding block 185 is slidably connected to the slide rail 183. Since different geographical latitudes and different terrain elevations affect the optimal setting angle of the solar photovoltaic panel 170, an adjustment can be made using the angle adjustment device 180 during the initial installation of the equipment. Specifically, the movement of the sliding block 185 on the slide rail 183 drives the lifting shaft 184 to move and rotate, thereby lifting the solar photovoltaic panel 170 to flip upwards or causing the solar photovoltaic panel to flip downwards.

[0030] In some embodiments, the bottom of the sliding block 185 is slidably connected to the slide rail 183 via a sliding groove. A threaded rod 186 is provided through one side of the sliding block 185, and one side of the threaded rod 186 passes through the sliding groove and abuts against the slide rail 183. The other end of the threaded rod 186 is coaxially connected to a rotating ring 187. In this embodiment, after the initial position adjustment of the solar photovoltaic panel 170 is completed, the threaded rod 186 can be rotated so that it abuts against the slide rail 183. At this time, the sliding block will be fixed to the slide rail 183, and the solar photovoltaic panel 170 will be stably fixed on the top of the power generation trolley 100.

[0031] In some embodiments, a plurality of heat dissipation components 113 are provided on the vehicle body 110, and the heat dissipation components 113 are connected to the cavity 111. In this embodiment, by providing heat dissipation components 113, high temperatures caused by heat generation during the operation of the inverter component 150 and the energy storage battery component 160 are avoided.

[0032] In some embodiments, a plug assembly 114 is provided at the rear end of the vehicle body 110. The plug assembly 114 is electrically connected to the energy storage battery assembly 160, and a socket assembly matching the plug assembly 114 is provided in the protective chamber 210. In this embodiment, the daytime power generation vehicle 100 leaves the chamber to generate electricity, and at night, the power generation vehicle 100 returns to the protective chamber 210. Under the restriction and guidance of the guide rail 300, the plug assembly 114 of the power generation vehicle 100 will accurately dock with the socket assembly, at which time the energy storage battery assembly 160 can be connected to the grid. The advantage of this embodiment is that the power generation vehicle 100 and the power grid are eliminated, avoiding the traction and influence of the power line on the power generation vehicle 100 during movement.

[0033] In some embodiments, the guide rail 300 is made of iron, and the blocking member 310 is a magnet. In this embodiment, the operator periodically moves the position of the magnet according to different time periods, thereby controlling the final stopping position of the generator trolley 100. The magnet can automatically adhere to the guide rail 300, making the operation convenient and quick.
