Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic modules, and specifically relates to an installation structure of a photovoltaic module. Background Art

[0002] Most of the solar photovoltaic module fixing frames used in the market can only provide one installation method, that is, installed on a flat roof or an inclined ridge. When the illumination angle changes due to seasonal alternation, it is inconvenient to adjust the angle of the solar photovoltaic module fixing frame, which is not conducive to the installation of solar photovoltaic modules and limits the practicality of the solar photovoltaic module fixing frame.

[0003] Chinese invention patent CN116961535A discloses a fixing structure and a photovoltaic module based on the installation of a photovoltaic module. The clamping mechanism cooperates with the support frame to clamp and fix the photovoltaic panel to ensure the stability of the photovoltaic panel. The driving cylinder drives the connecting frame to lift, and one end of the support frame displaces relative to the connecting frame through a sliding mechanism, thereby realizing the lifting of one end of the support frame. The arranged rotating shaft cooperates with the rotating seat and the connecting rod to realize the hinged positioning of the other end of the support frame, so that the entire support frame is adjusted in elevation angle, and then the angle of the photovoltaic panel is adjusted to improve the photoelectric conversion efficiency of the photovoltaic panel.

[0004] In the prior art, for the adjustment of photovoltaic panels, elevation angle adjustment is mostly adopted. However, throughout the year, except for the spring equinox and the autumn equinox, the daily path of the sun forms an inclined arc in the view of observers in the northern hemisphere. The degree of inclination depends on the latitude and season of the observer. The higher the latitude, the lower the path of the sun in the sky and the greater the degree of inclination of the daily path. Therefore, simple elevation angle adjustment cannot enable the photovoltaic panel to receive light to the greatest extent. Summary of the Invention

[0005] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and the title of the utility model of this application, to avoid obscuring the purpose of this part, the abstract of the specification, and the title of the utility model. However, such simplifications or omissions shall not be used to limit the scope of the utility model.

[0006] To solve the problems existing in the above background art, the utility model adopts the following technical solutions.

[0007] An installation structure of a photovoltaic module, comprising a bracket, on which a photovoltaic frame is movably installed, and a photovoltaic installation frame is rotatably connected to the photovoltaic frame. A photovoltaic panel is laid in the photovoltaic installation frame. A first screw rod is rotatably connected to the front surface of the bracket, and a rod sleeve is movably sleeved on the first screw rod. A first T-shaped connecting piece is fixedly connected to the side surface of the rod sleeve. A second T-shaped connecting piece is fixedly arranged on the front end side surface of the photovoltaic frame, and the second T-shaped connecting piece and the first T-shaped connecting piece are connected by a pin. An adjusting assembly is assembled on the photovoltaic frame, and one end of the adjusting assembly is connected to the photovoltaic installation frame. By pushing and pulling the photovoltaic installation frame through the adjusting assembly, the photovoltaic installation frame rotates on the photovoltaic frame at an angle.

[0008] The adjusting assembly includes a pair of third shaft seats fixedly installed on the inner side surface of the photovoltaic frame. A second screw rod is sleeved in the third shaft seats. A screw sleeve clamp is sleeved on the second screw rod. A connecting rod is hinged to the screw sleeve clamp. The end of the connecting rod is rotatably connected to a connecting piece, and the connecting piece is connected to the side edge of the photovoltaic installation frame at a position deviated from the center.

[0009] A pair of third shaft seats are arranged vertically and obliquely installed on the photovoltaic frame. One side of the screw sleeve clamp is thickened and provided with a groove, and one end of the connecting rod is connected to the groove opened on the side surface of the screw sleeve clamp by a pin.

[0010] One end of the second screw rod close to the photovoltaic frame can be connected to a driver, and the driver directly obtains power from the photovoltaic module.

[0011] Both ends of the upper surface of the photovoltaic frame are provided with cross bars, and a second shaft seat is arranged in the middle of the upper surface of the cross bars. The front and rear ends of the photovoltaic installation frame are both provided with pin pieces in the middle, and a short shaft is arranged on the outer surface of the pin pieces and inserted into the second shaft seat. A cross beam is connected between the lower ends of the pin pieces.

[0012] First shaft seats are symmetrically arranged on the front surface of the bracket. An installation cylinder is inserted between the first shaft seats. A motor is installed at one end of the first screw rod, and the motor is placed in the installation cylinder.

[0013] Hinges are symmetrically arranged on the upper surface of the bracket, and the bracket is movably connected to a square pipe by the hinges. The lower surface of the photovoltaic frame is welded to the square pipe.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] The bracket in the present utility model belongs to one of the photovoltaic modules. Based on the existing technology that can adjust the elevation angle, the bracket can also adjust the azimuth angle. Through the combination of these two angle adjustments, the photovoltaic panel can be dynamically aligned with the sun by adjusting the elevation angle and azimuth angle, ensuring that the panel faces the sun throughout different times of the day and different seasons, thereby maximizing the reception of solar radiation. This dynamic adjustment ability can significantly improve the energy conversion efficiency of the photovoltaic system. Moreover, through the comprehensive adjustment of the elevation angle and azimuth angle, the photovoltaic system can avoid or reduce the shadow occlusion of surrounding buildings, trees and other obstacles, ensuring that the panel receives sufficient sunlight for most of the day.

[0016] (2) As the seasons change, the position of the sun in the sky changes. The elevation angle adjustment can adjust the tilt angle of the panel to adapt to the elevation angle change of the sun in different seasons, while the azimuth angle adjustment can adjust the direction of the panel to adapt to the movement trajectory of the sun from east to west. This seasonal adjustment ability ensures that the photovoltaic system maintains a high energy collection efficiency throughout the year. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the accompanying drawings of the specification.

[0024] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Persons skilled in the art may make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0025] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present utility model. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive with other embodiments. The present utility model provides the following embodiments.

[0026] Refer to Figure 1 and Figure 2 For the installation structure of the photovoltaic module in this embodiment, the installation structure of the photovoltaic module in this embodiment includes a bracket 100, a photovoltaic frame 200 is movably installed on the bracket 100, and a photovoltaic installation frame 204 is rotatably connected to the photovoltaic frame 200. The bracket 100, the photovoltaic frame 200 and the photovoltaic installation frame 204 in this embodiment together form a support system in the photovoltaic module, and a photovoltaic panel 204a is laid in the photovoltaic installation frame 204.

[0027] Refer to Figure 3, Further, in order to realize the elevation angle adjustment of the photovoltaic frame 200, in this embodiment, hinges 101 are symmetrically provided on the upper surface of the bracket 100, and the bracket 100 is movably connected with square tubes by means of the hinges 101. The lower surface of the photovoltaic frame is welded to the square tubes. At the same time, in this embodiment, a first screw rod 104 is rotatably connected to the front surface of the bracket 100, and a rod sleeve 104a is movably sleeved on the first screw rod 104. A first T-shaped connecting piece 104b is fixedly connected to the side surface of the rod sleeve 104a. A second T-shaped connecting piece 201b is fixedly provided on the front side surface of the photovoltaic frame 200, and the second T-shaped connecting piece 201b and the first T-shaped connecting piece 104b are connected by a pin. First shaft seats 102 are symmetrically provided on the front surface of the bracket 100, and a placement cylinder 103 is inserted between the first shaft seats 102. One end of the first screw rod 104 is provided with a motor, and the motor is placed in the placement cylinder 103. In this embodiment, the first screw rod 104 is driven to rotate by the motor, and the rod sleeve 104a sleeved on the first screw rod 104 rises and falls as the first screw rod 104 rotates clockwise or counterclockwise. During the rising and falling process of the rod sleeve 104a, the first T-shaped connecting piece 104b connected to the rod sleeve 104a rises and falls synchronously, and the second T-shaped connecting piece 201b movably connected to the first T-shaped connecting piece 104b pulls one end of the photovoltaic frame 200 to move synchronously. Since the photovoltaic frame 200 is installed on the square tube, and the square tube is connected to the bracket 100 through the hinge 101, the elevation angle adjustment of the photovoltaic frame 200 on the bracket 100 is realized. The first T-shaped connecting piece 104b and the second T-shaped connecting piece 201b are mainly for adapting to the angle self-adaptation after the photovoltaic frame 200 rotates and preventing collision. When the photovoltaic frame 200 rotates due to the rising and falling of the rod sleeve 104a, it collides with the first screw rod 104. Therefore, the setting of the first shaft seat 102 and the placement cylinder 103 can enable the first screw rod 104 to also perform a certain angle self-adaptation.

[0028] Refer to Figure 3 and Figure 4, in this embodiment, in order to better enable the photovoltaic panel 204a to receive sunlight, the azimuth angle adjustment of the photovoltaic panel 204a is also provided. The specific adjustment process is as follows: In this embodiment, an adjustment assembly 202 is assembled on the photovoltaic frame 200, and one end of the adjustment assembly 202 is connected to the photovoltaic installation frame 204. By pushing and pulling the photovoltaic installation frame 204 through the adjustment assembly 202, the photovoltaic installation frame 204 rotates in azimuth on the photovoltaic frame 200; further, the adjustment assembly 202 includes a pair of third shaft seats 202c fixedly installed on the inner side surface of the photovoltaic frame 200. A second screw rod 202a is sleeved in the third shaft seat 202c. A screw sleeve clamp 202b is sleeved on the second screw rod 202a. A connecting rod 202d is hinged on the screw sleeve clamp 202b. The end of the connecting rod 202d is rotatably connected to a connecting piece 202d-1, and the connecting piece 202d-1 is connected to the side of the photovoltaic installation frame 204 at a position deviated from the center. In this embodiment, a driver can be connected to one end of the second screw rod 202a close to the photovoltaic frame 200. The driver directly obtains power from the photovoltaic module. The second screw rod 202a is driven to rotate by the driver. When the second screw rod 202a rotates, the screw sleeve clamp 202b sleeved on the second screw rod 202a rises and falls as the second screw rod 202a rotates clockwise or counterclockwise. When the screw sleeve clamp 202b rises and falls, the connecting rod 202d rotatably connected to it will push and pull the photovoltaic installation frame 204. Both ends of the upper surface of the photovoltaic frame 200 are provided with crossbars 201, and a second shaft seat 201a is provided in the middle of the upper surface of the crossbar 201. The front and rear ends of the photovoltaic installation frame 204 are both provided with pin pieces 203a in the middle, and a short shaft is provided on the outer surface of the pin piece 203a and inserted into the second shaft seat 201a. Therefore, when the photovoltaic installation frame 204 is pushed and pulled by the connecting rod 202d, it will tilt left and right on the photovoltaic frame 200, thereby realizing the azimuth angle adjustment. In order to ensure the structural stability, in this embodiment, a cross beam 203 is connected between the lower ends of the pin pieces 203a.

[0029] It should be noted that in order to prevent the photovoltaic installation frame 204 from colliding due to angle problems when the adjustment assembly 202 pushes the photovoltaic installation frame 204, in this embodiment, a pair of third shaft seats 202c are arranged vertically and obliquely installed on the photovoltaic frame 200. At the same time, in order to ensure that the connection between the connecting rod 202d and the screw sleeve clamp 202b does not affect the sleeving of the screw sleeve clamp 202b and the second screw rod 202a, in this embodiment, one side of the screw sleeve clamp 202b is thickened and provided with a groove, and one end of the connecting rod 202d is connected to the groove opened on the side surface of the screw sleeve clamp 202b by a pin.

[0030] The above content is a further detailed description of the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model pertains, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope determined by the claims submitted for the present utility model.
