Description

[0002] A photovoltaic (PV) system is a power generation system that uses the photovoltaic effect of solar cells to directly convert solar radiation energy into electrical energy. In large-scale applications, specialized energy storage devices are often used to centrally store the power generated by multiple PV structures.

Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1

[0031] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a photovoltaic energy storage device with wind resistance function. The photovoltaic energy storage device with wind resistance function includes a photovoltaic energy storage module 100 and a wind resistance module 200. By setting the wind resistance module 200, when encountering external wind force, the wind volume is automatically reduced and buffer protection is provided to improve the overall wind resistance performance of the device. In windy weather, it can automatically lock and position itself to ensure the overall stability of the device, effectively cope with external wind, and improve the applicability of the device.

[0032] Specifically, the photovoltaic energy storage module 100 includes a base 101, an energy storage battery 102 is provided on the top of the base 101, a support frame 103 is fixed on the top of the base 101, a fixed frame 103a is fixed on the top of the support frame 103, a first photovoltaic panel 103a-1 is fixed inside the fixed frame 103a, a movable frame 104 is movably connected to one end of the fixed frame 103a, and a second photovoltaic panel 104a is fixed inside the movable frame 104.

[0033] Long anchor rods are installed at all four corners of the base 101. The long anchor rods are driven into the installation position of the device to ensure the overall stability of the device.

[0034] The first photovoltaic panel 103a-1 and the second photovoltaic panel 104a convert electrical energy. First, the power is optimized and the charge and discharge are controlled by the photovoltaic controller. Then, the voltage level is adjusted by the DC-DC converter. Finally, combined with the real-time monitoring of the BMS, the electrical energy is stored in the energy storage battery 102. The working principle of this part is the prior art, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0035] Specifically, the wind-resistant component 200 is set on the top of the base 101 and includes a vertical rod 201 and a reinforcing sleeve 204. The vertical rod 201 is fixed to the top of the base 101, and the reinforcing sleeve 204 is set on the side of the base 101. An auxiliary seat 207 is fixed to the top of the vertical rod 201. A locking rod 207a is slidably connected to one side of the auxiliary seat 207. A positioning rod 202 is slidably connected to the top of the auxiliary seat 207. A displacement seat 203 is slidably connected to the vertical rod 201. A support plate 203a is rotatably connected to the top of the displacement seat 203. A first spring 203b is fixed to the bottom of the displacement seat 203. A support plate 203c is rotatably connected to the bottom of the displacement seat 203. A locking block 203c-1 is rotatably connected to the other end of the support plate 203c.

[0036] By setting up the vertical rod 201 and the displacement seat 203, the vertical rod 201 can position and guide the displacement of the displacement seat 203, ensuring the stability of the displacement seat 203's movement. When the displacement seat 203 is pressed down, it will move down synchronously at the upper end of multiple support plates 203c, thereby driving multiple locking blocks 203c-1 to move outward and be placed into the reinforcing sleeve 204, where they will be affected by wind force, improving the overall stability of the device.

[0037] Example 2

[0038] Reference Figures 2-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the auxiliary seat 207 has a sliding groove 207b, which cooperates with the positioning rod 202. The top of the positioning rod 202 is rotatably connected to the bottom of the movable frame 104.

[0040] By setting the slide 207b, displacement space can be provided for the positioning rod 202, while limiting the movement stroke of the positioning rod 202 to prevent excessive displacement of the positioning rod 202. The positioning rod 202 will change its top position as the movable frame 104 moves.

[0041] A second spring 207a-1 is sleeved on one end of the clamp rod 207a. One end of the second spring 207a-1 is fixedly connected to the auxiliary seat 207, and the other end of the second spring 207a-1 is fixedly connected to the clamp rod 207a. A pressing head 207a-2 is fixed to the other end of the clamp rod 207a.

[0042] The lever 207a is T-shaped, which provides installation space for the second spring 207a-1. The presence of the second spring 207a-1 provides elastic connection force for the lever 207a, preventing the lever 207a from sliding and displacing arbitrarily.

[0043] The pressure head 207a-2 is hemispherical in shape. Due to its geometric design, it reduces the sliding contact friction and can decompose the contact force into normal and tangential components. In contrast, the rectangular head design has a right-angled structure on its contact surface that easily generates lateral force, increasing frictional resistance and leading to increased wear.

[0044] A vertical groove 202a is provided on one side of the positioning rod 202, and a locking hole 202c is provided on the positioning rod 202. Both the vertical groove 202a and the locking hole 202c are engaged with the pressing head 207a-2.

[0045] The vertical groove 202a provides vertical displacement space for the pressure head 207a-2, while limiting the vertical displacement stroke of the positioning rod 202 to prevent the positioning rod 202 from disengaging from the pressure head 207a-2.

[0046] The design of the locking hole 202c provides insertion space for the locking rod 207a, preventing the positioning rod 202 from sliding or shifting arbitrarily when the two are installed together.

[0047] The vertical groove 202a is connected to the locking hole 202c. The pressing head 207a-2 is located in the vertical groove 202a. When the positioning rod 202 moves down, the pressing head 207a-2 slides in the vertical groove 202a. When the positioning rod 202 continues to move down, so that the locking rod 207a is aligned with the locking hole 202c, under the elastic support of the second spring 207a-1, the locking rod 207a will reset and pass through the locking hole 202c, limiting the positioning rod 202 and preventing it from moving further.

[0048] The top of the support plate 203a is rotatably connected to the bottom of the movable frame 104, and the bottom of the first spring 203b is fixed to the top of the base 101.

[0049] By setting the first spring 203b, elastic support force can be provided for the displacement seat 203, maintaining the displacement seat 203 in a high position without external force, and preventing the displacement seat 203 from moving down at will.

[0050] The number of support plates 203c and reinforcing sleeves 204 are the same, and the locking block 203c-1 is slidably connected inside the reinforcing sleeve 204.

[0051] The reinforcing sleeve 204 is pre-embedded at the device installation location, and the installation location is reserved to allow for the displacement of the locking block 203c-1. The reinforcing sleeve 204 is fixed in the appropriate position by short anchor rods.

[0052] A long guide rod is fixed inside the reinforcing sleeve 204. The length of the long guide rod is greater than the inner diameter of the reinforcing sleeve 204. The long guide rod passes through the locking block 203c-1 and is slidably connected with the locking block 203c-1 to guide the displacement of the locking block 203c-1 and ensure the stability of the locking block 203c-1's movement.

[0053] A protruding rod 202b is fixed on the positioning rod 202, and a connecting plate 206 is rotatably connected to the protruding rod 202b. A protective shell 205 is provided at one end of the connecting plate 206, and it cooperates with the energy storage battery 102.

[0054] By setting the protruding rod 202b, one end of the linkage connecting plate 206 can be displaced when the positioning rod 202 moves up and down.

[0055] By setting the protective shell 205, the energy storage battery 102 can be covered and shielded when the downward movement is completed, so as to avoid damage to the energy storage battery 102 caused by collision between debris and the energy storage battery 102 in windy weather (strong winds are more likely to pick up heavy or hard objects, such as branches or small stones, and the impact force carried by debris is greater).

[0056] A fixing head 205a is fixed to the top of the protective shell 205. The fixing head 205a is rotatably connected to one end of the connecting plate 206. A diverting arc plate 205c is fixed on the protective shell 205.

[0057] By setting up the diversion arc plate 205c, the arc shape can be used to guide the wind to the side, thereby reducing the wind force on the device and helping to maintain the stability of the device.

[0058] A guide plate 101a is fixed on the top of the base 101. The guide plate 101a is located outside the energy storage battery 102. A guide groove 205b is opened on the outside of the protective shell 205 and cooperates with the guide plate 101a.

[0059] There are four guide plates 101a. The guide plates 101a can play an auxiliary positioning role. When installing the energy storage battery 102, it is helpful for the staff to install the energy storage battery 102 quickly and accurately. The guide plates 101a can also work with the guide groove 205b to guide the vertical displacement of the protective shell 205 and ensure the stability of the protective shell 205.

[0060] The guide plate 101a has a rubber pad fixed on its inner side. During the installation of the energy storage battery 102, even if it accidentally comes into contact with the energy storage battery 102, it can provide elastic buffer protection. Moreover, it is made of insulating material, which makes it safer.

[0061] A baffle 103a-2 is fixed on one side of the fixed frame 103a. The baffle 103a-2 is inclined and the inclination angle is the same as that of the fixed frame 103a.

[0062] By setting the baffle 103a-2, the upward rotation stroke of the movable frame 104 can be limited, ensuring that the tilt angle of the movable frame 104 is in a suitable position, which meets the requirements of high-efficiency photoelectric conversion.

[0063] When in use, the fixed frame 103a and the movable frame 104 are at the same tilt angle. In this state, the first photovoltaic panel 103a-1 and the second photovoltaic panel 104a can perform good photoelectric conversion, and the electrical energy is stored in the energy storage battery 102.

[0064] When exposed to external wind, the movable frame 104 will rotate downward around the fixed frame 103a, gradually approaching a horizontal state, effectively reducing the wind force. In the event of strong winds, the movable frame 104 will rotate to a horizontal state and lock, completing the reinforcement operation and ensuring the overall stability of the device. Since strong winds generally last for a long time, the locking operation in this device is more in line with actual usage needs. After the strong winds subside, the user can manually unlock the device. The unlocking operation involves pulling the lever 207a to displace it from the locking hole 202c, causing the pressure head 207a-2 to re-enter the vertical groove 202a.

[0065] During the rotation of the movable frame 104, the linkage positioning rod 202 and the support plate 203a move. The positioning rod 202 slides downward in the slide groove 207b, the pressing head 207a-2 slides in the vertical groove 202a, and the movement of the support plate 203a causes the displacement seat 203 to gradually move downward on the vertical rod 201. The first spring 203b is compressed to play a buffering and protective role.

[0066] When the wind is strong, as the positioning rod 202 gradually moves down, the locking rod 207a will align with the locking hole 202c. Under the elastic connection of the second spring 207a-1, the locking rod 207a passes through the positioning rod 202 and locks the position of the positioning rod 202, preventing the movable frame 104 from continuing to rise or fall and keeping the movable frame 104 in a horizontal state, which helps to reduce the overall wind volume.

[0067] At the same time, the support plate 203a moves further to make the displacement seat 203 move further down. With the cooperation of the support plate 203c, the locking block 203c-1 is placed into the reinforcing sleeve 204, which will distribute the wind force to multiple installation positions and improve the overall wind resistance of the device.

[0068] As the positioning rod 202 moves downward, the connecting plate 206, in conjunction with the protruding rod 202b, drives the protective shell 205 to gradually move downward, completing the coverage and protection of the energy storage battery 102, resulting in better overall protection performance.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
