Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic components, and in particular to a light-chasing and follow-up photovoltaic panel installation component. Background Art

[0002] Photovoltaic power generation technology is relatively mature. During the specific operation process, it is necessary to consider conditions such as lighting conditions and environmental parameters, and the lighting conditions are one of the key factors affecting power generation efficiency. During the field operation and installation process, reference can be made to the relevant contents in publication numbers CN114859982A and CN117856719A.

[0003] Specifically, the installation angle of the photovoltaic panel is changed according to the light intensity and fixed time period. Its essence is to change the overall mounting angle with the motor structure, but its later maintenance cost is relatively high, especially in harsh environments such as storms and rainstorms. The movable installation components are more susceptible to wear than the fixed installation components. The tracking components based on the motor structure have reduced stability and may even lose the tracking function, and will indirectly affect the installation stability of the photovoltaic panel.

[0004] Moreover, in the whole photovoltaic array, the power generation efficiency of each photovoltaic panel is not the same. If the adjustment method only relies on the light intensity and fixed time period, it is not fully adapted to the operation requirements of each photovoltaic panel in the photovoltaic array. This application proposes a solution. Summary of the invention

[0005] The purpose of the present invention is to provide a light-chasing and follow-up photovoltaic panel installation component. For conventional light-chasing photovoltaic panel installation components, the installation stability of the conventional light-chasing structure is lower than that of the fixed installation method, and even the tracking function is lost due to mechanical wear when encountering harsh environments. In addition, the adjustment method that only relies on light intensity and fixed time period cannot fully meet the operation requirements of the photovoltaic array.

[0006] The object of the present invention can be achieved by the following technical solutions: A light-following photovoltaic panel mounting assembly comprises a mounting base, a mounting frame and a photovoltaic panel, wherein the photovoltaic panel is mounted on the mounting frame, and a connecting shaft and a directional shaft are provided between the mounting frame and the mounting base;

[0007] The orientation shaft is rotatably connected to the connecting shaft, the connecting shaft is rotatably connected to the mounting frame and fixedly connected to the mounting base, and the orientation shaft is rotatably connected to the mounting base;

[0008] A rocker arm portion is provided on the connecting shaft, and the rocker arm portion is linearly and equidistantly arranged along the length direction of the connecting shaft. A wing arc plate is provided at the position of the directional shaft corresponding to the rocker arm portion, an electric push rod is installed at the position of the mounting base corresponding to the rocker arm portion, and a universal joint sleeve corresponding to the rocker arm portion is provided at the end position of the output shaft of the electric push rod.

[0009] It is further configured that: the rocker arm portion is located at a lower side of the orientation axis.

[0010] It is further configured as follows: a spherical connector is provided between the end position of the output shaft of the electric push rod and the universal joint sleeve, and the universal joint sleeve is rotatably connected in the rocker arm portion.

[0011] It is further configured as follows: a plurality of pneumatic telescopic cylinders are installed on the upper curved surface position of the universal joint sleeve corresponding to the wing arc plate, and a roller is rotatably installed on the end position of the output shaft of the pneumatic telescopic cylinder.

[0012] It is further configured as follows: the arrangement direction of the pneumatic telescopic cylinder is inclined along the horizontal direction, and the inclined direction of the pneumatic telescopic cylinder is symmetrically arranged along the linear direction of the installation frame.

[0013] It is further configured as follows: an air cavity is provided in the pneumatic telescopic cylinder, and the air cavities in each pneumatic telescopic cylinder in the universal joint sleeve are communicated with each other.

[0014] It is further configured as follows: the wing arc plate consists of a mounting sleeve and two wing plates, the two wing plates are installed on the curved surfaces on both sides of the mounting sleeve along the setting direction of the pneumatic telescopic cylinder, and the cross-section of the two wing plates after being combined through the mounting sleeve is crescent-shaped.

[0015] It is further configured that: the electric push rods in the rocker arm parts in two adjacent positions are arranged in mirror symmetry.

[0016] It is further configured as follows: the connecting shaft is arranged at the middle position of the corresponding mounting frame, the mounting frame rotates clockwise or counterclockwise on the mounting base through an electric push rod, a universal joint sleeve, and a wing arc plate, and the mounting frame performs the rotation action with the power generation capacity of the photovoltaic panel as a reference signal.

[0017] The present invention has the following beneficial effects:

[0018] 1. For the light-chasing process of photovoltaic panels, the electric push rod is used as the power structure, and the directional shaft and the connecting shaft are used as the transmission structure. Specifically, by limiting the connection mode of the directional shaft and the connecting shaft relative to the mounting frame, the mounting frame is fixed on the mounting base through the connecting shaft, but the mounting frame and the connecting shaft keep rotating, and on this basis, an directional shaft corresponding to the connecting shaft is added, and the inclination angle of the mounting frame is changed by the flying wing arc plate on the directional shaft. More specifically, the middle end position of the mounting frame is deflected clockwise or counterclockwise relative to the connecting shaft to cooperate with the photovoltaic panel to receive the maximum light intensity;

[0019] 2. Based on the above content, the overall process is to cooperate with the linear movement process of the electric push rod to convert it into an arc-shaped force through the universal joint sleeve, and further use the pneumatic telescopic cylinder to support the wing arc plate, thereby changing the inclination angle of the mounting frame. The inclination direction of each pneumatic telescopic cylinder is further limited. Its purpose is to provide two-way support for the wing arc plate to maintain the stability of the overall photovoltaic panel. In the overall light-chasing process, the power generation capacity of a single photovoltaic panel is the main factor, supplemented by adjustments such as fixed time periods, so as to reduce the degree of movement during the light-chasing process.

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: For conventional tracking photovoltaic panel installation components, the installation stability of conventional tracking structures is lower than that of fixed installation methods, and even loses the tracking function due to mechanical wear in harsh environments. In addition, the adjustment method that only relies on light intensity and fixed time periods cannot fully meet the operation requirements of photovoltaic arrays. The following technical solutions are proposed:

[0030] Reference Figures 1 to 6 In this embodiment, a light-following photovoltaic panel mounting assembly comprises a mounting base 1, a mounting frame 2 and a photovoltaic panel 3. The photovoltaic panel 3 is mounted on the mounting frame 2. A connecting shaft 7 and an orientation shaft 6 are provided between the mounting frame 2 and the mounting base 1.

[0031] The orientation shaft 6 is rotationally connected to the connecting shaft 7, the connecting shaft 7 is rotationally connected to the mounting frame 2 and is fixedly connected to the mounting base 1, and the orientation shaft 6 is rotationally connected to the mounting base 1;

[0032] A rocker arm portion 8 is provided on the connecting shaft 7, and the rocker arm portion 8 is linearly and equidistantly arranged along the length direction of the connecting shaft 7. A wing arc plate 5 is provided at the position of the directional shaft 6 corresponding to the rocker arm portion 8, and an electric push rod 4 is installed at the position of the mounting base 1 corresponding to the rocker arm portion 8. A universal joint sleeve 9 corresponding to the rocker arm portion 8 is provided at the end position of the output shaft of the electric push rod 4. The rocker arm portion 8 is located at the lower side of the directional shaft 6, and a spherical connecting piece is provided between the end position of the output shaft of the electric push rod 4 and the universal joint sleeve 9. The universal joint sleeve 9 is rotatably connected in the rocker arm portion 8. A plurality of pneumatic telescopic cylinders 10 are installed at the upper curved surface position of the universal joint sleeve 9 corresponding to the wing arc plate 5, and a roller 11 is rotatably installed at the end position of the output shaft of the pneumatic telescopic cylinder 10.

[0033] Basic principle: A brief description of the installation operation of photovoltaic power generation is given. The installation base 1 is installed at a selected position, and the installation frame 2 and the photovoltaic panel 3 are installed in accordance with the conventional operation method. However, the difference is that: first, the connecting shaft 7 is installed on the installation frame 2 in a rotating connection manner to ensure that the installation frame 2 can rotate freely on the connecting shaft 7, but the connecting shaft 7 is installed on the installation base 1 in a fixed form, and the directional shaft 6 is further installed in a rotating form based on the connecting shaft 7, so as to cooperate with the directional shaft 6 to install the wing arc plate 5, and the wing arc plate 5 is installed on the lower side of the installation frame 2. It should be briefly explained that: Figure 1 For example, the setting position / setting direction of the connecting shaft 7 matches the center position of the overall mounting frame 2 along the linear direction, which essentially ensures that the overall mounting frame 2 can be bidirectionally deflected along the setting position of the connecting shaft 7;

[0034] It should be noted that: depending on the setting position of the photovoltaic panel 3, in the initial state, the entire photovoltaic panel 3 can be set in an inclined direction or a horizontal direction, but the light chasing is carried out according to the lighting conditions. The light chasing process specifically depends on the action process of the electric push rod 4 cooperating with the connecting shaft 7, the directional shaft 6 and the universal joint sleeve 9.

[0035] Embodiment 2: Explanation of the light-chasing process in Embodiment 1:

[0036] The setting direction of the pneumatic telescopic cylinder 10 is inclined along the horizontal direction, and the inclined direction of the pneumatic telescopic cylinder 10 is symmetrically arranged along the linear direction of the mounting frame 2. An air cavity is arranged in the pneumatic telescopic cylinder 10, and the air cavities in each pneumatic telescopic cylinder 10 in the universal joint sleeve 9 are connected. The wing arc plate 5 is composed of a mounting sleeve and two wing plates. The two wing plates are installed on the curved surfaces on both sides of the mounting sleeve along the setting direction of the pneumatic telescopic cylinder 10. The cross-section of the two wing plates after being combined by the mounting sleeve is crescent-shaped. The electric push rod 4 in the rocker arm part 8 in two adjacent positions is mirror-symmetrically arranged, and the wing arc plate 5 is fixedly connected to the mounting frame 2.

[0037] Solution description: The light-chasing structure proposed in the present invention is based on the linear movement process of the electric push cylinder 4. Figure 4 and Figure 5 For illustration, it is assumed that the photovoltaic panel 4 in the initial state remains relatively horizontal, and the corresponding universal joint sleeve 9 is set at the same position as Figure 6 The position shown in the figure is consistent, wherein the wing plate in the wing arc plate 5 is supported by multiple pneumatic telescopic cylinders 10, so as to ensure that the entire photovoltaic panel 3 maintains a horizontal state, specifically including the following contents:

[0038] S1: If the photovoltaic panel 3 is installed in a sudden storm or other severe weather, it will also cause the photovoltaic panel 3 to deflect in both directions within a small range. For this, it is necessary to further limit the setting angle of each pneumatic telescopic cylinder 10. Specifically, Figure 5 In the position shown in the figure, the number of pneumatic telescopic cylinders 10 provided on a single universal joint sleeve 9 is at least two, and the setting angle of the pneumatic telescopic cylinder 10 is further limited to Figure 6 For example, if one of the pneumatic telescopic cylinders 10 is tilted to the left along the vertical direction, then the other pneumatic telescopic cylinder 10 is tilted to the right along the vertical direction. The essence is to form a triangular support structure with multiple pneumatic telescopic cylinders 10 and wing arc plates, and specifically support the possible deflection direction of the overall installation frame 2, which is used to preliminarily improve the installation stability of the photovoltaic panel 3;

[0039] S2: Supplementary explanation is given based on the content in S1. When the overall installation frame 2 needs to be adjusted, the electric push rod 4 is pneumatically driven to provide linear thrust to the overall universal joint sleeve 9. However, because the universal joint sleeve 9 is set on the rocker arm part 8 in a "fixed" manner, it will not drive the universal joint sleeve 9 and the connecting shaft 7 to move in a linear direction. However, because a spherical connector is set between the output shaft of the electric push rod 4 and the universal joint sleeve 9, the universal joint sleeve 9 is driven to rotate slightly on the rocker arm part 8 under the action of the electric push rod 4. The purpose is to further change the setting angle of each pneumatic push cylinder 10, and further cooperate with the wing arc plate 5 to change the setting angle of the overall installation frame 2.

[0040] S3: Further explanation of S2 content, and reference Figure 6 , a roller 11 is rotatably installed at the end position of the output shaft of each pneumatic push cylinder 10, and its essence is to ensure that the roller 11 always contacts the lower curved surface of the wing plate. In order to ensure that the installation frame 2 is driven to deflect by the wing arc plate 5, it is necessary to ensure that the pneumatic push cylinders 10 on both sides of the arc length direction of the wing arc plate 5 are independently supported, and the pneumatic push cylinders 10 on one side are in a compressed state, but it is necessary to further limit the air cavity inside the pneumatic push cylinder 10 to be connected. The pneumatic push cylinder 10 in a compressed state can be used as a "power piece" to limit the pneumatic push cylinder 10 on the other side to be in an extended state. In essence, the pneumatic push cylinder 10 and the wing arc plate 5 still maintain a triangular structure, but in this case, on the one hand, because the air cavity inside each pneumatic push cylinder 10 is connected, the specific stroke of each pneumatic push cylinder 10 is "equally divided" according to the amount of air in the air cavity. On the other hand, because the overall angle of the overall universal joint sleeve 9 is tilted, it will also directly affect the angle of the wing arc plate 5, thereby driving the installation frame 2 to tilt at an angle;

[0041] In order to maintain the structural stability of the overall mounting frame 2, if two rocker arms 8 are provided on the overall connecting shaft 7, it is necessary to limit the setting position of the electric push rod 4 provided on the rocker arm 8, specifically, to limit the linear movement direction of the two electric push rods 4 to ensure that the linear movement directions of the two both point to the direction of the connecting shaft 7, but the linear movement directions of the two are exactly opposite to each other. The essence is: when it is necessary to adjust the setting angle of the mounting frame 2, if each electric push rod 4 generates a thrust on the universal joint sleeve 9, then the overall connecting shaft 7 is subjected to a "fixing force" in both directions, thereby stabilizing the universal joint sleeve 9 by fixing the installed connecting shaft 7.

[0042] Embodiment 3: Supplementary explanation on the overall light-chasing process:

[0043] The connecting shaft 7 is arranged at the middle position of the corresponding mounting frame 2. The mounting frame 2 is rotated clockwise or counterclockwise on the mounting base 1 through the electric push rod 4, the universal joint sleeve 9, and the wing arc plate 5. The mounting frame 2 performs the rotation action with the power generation capacity of the photovoltaic panel 3 as a reference signal.

[0044] Solution description: Combined with the light-chasing components in the current photovoltaic modules, the essence of the light-chasing components is based on weather information and time information. For example, on cloudy days, rainy days and other weather conditions, there is no need to perform light-chasing actions, while on sunny days, light-chasing actions are generally started based on photometers and time information. However, there are multiple photovoltaic power generation units in the overall photovoltaic power generation array. Using a photometer to detect light intensity and a fixed time period to control the light-chasing angle cannot fully adapt to the photovoltaic array.

[0045] In this regard, the present invention specifically focuses on the power generation capacity of a single photovoltaic panel 3 and coordinates it with a fixed time period. For example, under normal conditions, the light intensity is highest between 11:30 noon and 1:30 pm, so that the power generation capacity of the photovoltaic panel 2 is in the best state, and the power generation capacity at other times is slightly lower. Therefore, in the normal process, according to the fixed time period, if the fixed time period is 1 hour, the photovoltaic panel 3 is regularly rotated to a certain angle after 1 hour. However, in actual situations, there are differences in power generation capacity due to uncontrollable factors. For this, the main scheme adopted by the present invention is: in the overall photovoltaic power generation array, based on a single photovoltaic panel 3, when the current is collected into the electric energy storage structure, the power generation capacity of a single photovoltaic panel 3 can be monitored in real time by a current detection structure, and after a single fixed time period, if the power generation capacity of the photovoltaic panel 2 has not been significantly reduced, there is no need to rotate the inclination angle of the photovoltaic panel 3, but before the fixed time period is reached, if the power generation capacity of the photovoltaic panel 2 has already shown a significant downward trend, the photovoltaic panel 3 is rotated in the corresponding direction in the relevant manner in Example 2 so that the photovoltaic panel 3 is fully exposed to light.

[0046] In summary: the electric push rod is used as the power structural component, the directional shaft and the connecting shaft are used as the transmission structural components, and the connection mode of the mounting frame relative to the mounting base is limited by the directional shaft and the connecting shaft, wherein the mounting frame is arranged in a relatively fixed form through the connecting shaft, but the mounting frame and the directional shaft remain connected, so that it can be understood that the mounting frame only rotates on the connecting shaft through the directional shaft, and specifically limits the rotation direction of the mounting frame relative to the connecting shaft, specifically cooperates with the linear movement generated by the rocker arm part in the connecting shaft by multiple pneumatic telescopic cylinders, and cooperates with the two-way support process of the pneumatic telescopic cylinders for the wing arc plate, so as to achieve the purpose of adjusting the setting angle of the mounting frame, and the overall light chasing process is based on the power generation capacity of a single photovoltaic panel, supplemented by adjustments such as fixed time periods, thereby reducing the degree of movement during the light chasing process.
