[0039] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0042] Combine the following Figures 1 to 8 The photovoltaic support provided by the utility model is introduced with reference to a specific embodiment. The photovoltaic support comprises a support frame 1, a base 2 and a crossbeam 3.

[0043] Specifically, combined Figures 1 to 3 As shown, the support frame 1 includes a longitudinal beam 11, a horizontal beam 12 and a support rod 13. Figure 1The longitudinal beam 11 is extended in the direction indicated by the middle X-axis, and can overlap the photovoltaic modules so that the two ends of the photovoltaic modules can be supported by at least two longitudinal beams 11, and the longitudinal beam 11 is hingedly connected to the horizontal beam 12, so that the inclination angle of the photovoltaic module can be changed by adjusting the angle between the longitudinal beam 11 and the horizontal beam 12, so that its performance and efficiency meet the needs of users. In this embodiment, the longitudinal beam 11 is hingedly connected to the support rod 13, and the horizontal beam 12 is detachably fixedly connected to the support rod 13.

[0044] refer to Figure 4 As shown, the base 2 comprises a support seat 21, a column 22 and a clamping member 23. The two ends of the column 22 can be fixedly connected to the support seat 21 and the clamping member 23 respectively by welding or the like, and the clamping member 23 has a groove at one end away from the column 22, and the width of the groove is not less than the width of the horizontal beam 12, so that the horizontal beam 12 can be clamped in the groove.

[0045] It should also be noted that the design of the base 2 allows the entire photovoltaic power station to have a certain distance from the ground, avoiding the obstruction of weed growth, and also increases the incident light from the front to the ground, and then provides more diffuse light sources to the back panel of the photovoltaic module based on the ground, thereby improving the overall photovoltaic power generation capacity.

[0046] refer to Figure 1 As shown, the beam 3 is along Figure 1 The longitudinal beam 11 is extended in the direction shown by the Y axis, and the X axis and the Y axis are horizontally and vertically arranged, and the longitudinal beam 11 can also overlap the transverse beam 3 to effectively improve the structural strength and supporting stability of the entire photovoltaic support.

[0047] Preferably, in this embodiment, a photovoltaic module is supported on all sides by two longitudinal beams 11 and two transverse beams 3, so that the back of the photovoltaic module can meet 100% unobstructed conditions, thereby obtaining a large amount of diffuse reflected light on the back and below, having a very high ability to utilize light, achieving the best improvement in the back power generation design, and having a very good power generation advantage, thereby providing added value for the return on investment of the customer's power station.

[0048] During the specific operation and installation of the photovoltaic bracket, the operator first arranges the multiple bases 2 as required and places them in the designated area; then the horizontal beam 12 in each support frame 1 is clamped into the groove of the corresponding clamp 23 to fix the support frame 1; then the support frame 1 in the folded state is opened, so that the longitudinal beam 11 and the horizontal beam 12 are at a preset angle, and the other end of the support rod 13 away from the longitudinal beam 11 can be fixedly connected to the horizontal beam 12 by bolts, pins and other parts, so as to support the longitudinal beam 11; then the operator moves the crossbeam 3 to the longitudinal beam 11 and fixes it to the longitudinal beam 11. Multiple crossbeams 3 in the same row are arranged at intervals along the X-axis direction to ensure that the distance between two adjacent crossbeams 3 along the X-axis direction is not less than the length of a single photovoltaic module, thereby ensuring the installation of the photovoltaic module on the photovoltaic bracket.

[0049] Through the above installation operation method, it can be seen that the photovoltaic bracket has a simple structure, and the installation steps are simple and easy to implement. For household ground power stations with small single-unit capacity, it can be installed independently by the owner, and a professional construction team is no longer required to install the photovoltaic bracket, thereby effectively reducing installation costs and increasing power station profits.

[0050] In addition, it should be noted that the scale of the small power station can also be more flexible. The length of the beam 3 and the number of the longitudinal beams 11 can be expanded arbitrarily based on the Y direction, so as to obtain a photovoltaic bracket that can collect different total amounts of power generation. Moreover, from the overall material to the construction, it can be completed entirely by the customer's own efforts. No professional skills training or professional tools are required. Conventional general tools combined with simple guidance and operating specifications can allow ordinary adults with basic attempts to realize independent assembly and construction, thus providing a more economical solution for household photovoltaic applications.

[0051] It is understandable that in other embodiments, the support rod 13 can also be hingedly connected to the horizontal beam 12. When the support frame 1 is in a folded state, the support rod 13 can fit the horizontal beam 12, thereby reducing the volume of the support frame 1 and facilitating transportation and storage. When the support frame 1 is opened, the other end of the support rod 13 away from the horizontal beam 12 is fixedly connected to the longitudinal beam 11 through bolts, pins and other parts, so that the longitudinal beam 11 can be tilted and fixed as needed. Therefore, those skilled in the art can independently choose whether the support rod 13 is hingedly connected to the horizontal beam 12 or the longitudinal beam 11, and the utility model does not limit this.

[0052] Furthermore, in order to increase the supporting stability of the horizontal beam 12 on the longitudinal beam 11 , in this embodiment, a plurality of supporting rods 13 of different lengths are sandwiched between the longitudinal beam 11 and the horizontal beam 12 , thereby effectively reducing the shaking and trembling of the longitudinal beam 11 .

[0053] Furthermore, in this embodiment, the support rod 13 is a U-shaped component, and a slot is provided on the side facing the longitudinal beam 11. When the support frame 1 is in a folded state, the longitudinal beam 11 can be inserted into the slot so that the support rod 13 is completely attached to the longitudinal beam 11, thereby further reducing the folded volume of the support frame 1 and making the storage and transportation of the support frame 1 more convenient.

[0054] When the base 2 is placed on the horizontal installation surface of the installation area, it is also necessary to ensure the installation stability of the base 2 to prevent the base 2 from tilting and shifting. In order to achieve the above effect, in this embodiment, reference Figure 4 As shown, the support seat 21 includes a seat body 211 and a fastener 212, wherein the seat body 211 is provided with a through hole 2111, and the fastener 212 is a ground nail, which is limitedly passed through the through hole 2111 and inserted into the horizontal installation surface, thereby increasing the grip of the base 2, avoiding the base 2 from sliding on the horizontal installation surface, reducing the risk of the base 2 loosening and vibrating, and facilitating installation, and the assembly can be completed without the use of additional tools or equipment.

[0055] It should be noted that the shape of the seat body 211 can be round, square or special-shaped, so that the base 2 can meet different installation requirements and usage environments, thereby improving the flexibility and adaptability of installation.

[0056] Continue to refer Figure 4 As shown, in order to further increase the installation stability of the base 2, in this embodiment, the base 2 also includes a loading cylinder 24, both ends of which are open. After being sleeved on the column 22, the bottom end of the loading cylinder 24 is in contact with the top surface of the seat body 211. After the base 2 is fixed on the horizontal installation surface by ground nails, fillers such as cement, gravel, sand, soil or concrete can be placed in the loading cylinder 24, so that the weight of the entire base 2 can be further increased, thereby further improving the stability of the photovoltaic bracket, and effectively improving the wind load resistance of the photovoltaic bracket.

[0057] After connecting the cross beam 3 and the longitudinal beam 11, refer to Figure 1 As shown, the photovoltaic bracket provided in this embodiment can also improve the connection stability between the horizontal beam 12 and the cross beam 3 by adding an additional support frame 4, thereby further improving the structural strength and resistance to natural disasters of the photovoltaic bracket. The support frame 4 can be fixedly connected to the horizontal beam 12 and the cross beam 3 by bolts, screws or pins. This connection method is not only convenient to operate, but also firm and reliable.

[0058] The specific connection method of the cross beam 3 and the longitudinal beam 11 is described in detail below:

[0059] In this embodiment, combined with Figure 5 and Figure 6 As shown, the photovoltaic bracket also includes a connecting member 5, a threaded locking member 6 and a nut, wherein the connecting member 5 is overlapped on the top surface of the longitudinal beam 11, and a mounting groove 51 is opened on the top surface of the connecting member 5, and the bottom of the mounting groove 51 has a first mounting hole 501 and a second mounting hole 502; a first through hole is opened on the longitudinal beam 11, and a second through hole is opened on the cross beam 3.

[0060] For example, during the specific installation, the connector 5 is first overlapped on the longitudinal beam 11 of the support frame 1 in the folded state, and the first mounting hole 501 is arranged opposite to the first through hole, and the first mounting hole 501 and the first through hole are sequentially penetrated by the threaded locking member 6, and then the threaded connection is made to the nut; then the support frame 1 is opened to make it in the supporting state, and after the crossbeam 3 is moved over, the two ends of the crossbeam 3 are first inserted into the corresponding mounting through grooves 51, and the second through hole is arranged opposite to the second mounting hole 502, and the second mounting hole 502 and the second through hole are sequentially penetrated by the threaded locking member 6, and then the threaded connection is made to the nut, thereby achieving the fixed connection between the crossbeam 3 and the longitudinal beam 11. Since the connector 5 has a simple structure, by using the connection method of the threaded locking member 6, not only the complexity of the connection between the crossbeam 3 and the longitudinal beam 11 can be effectively reduced, but also the connection stability can be enhanced.

[0061] It should also be noted that in other embodiments, the cross beam 3 can also be installed to a position flush with the longitudinal beam 11, so that the cross beam 3 can not only enhance the stability of the entire photovoltaic support, but also assist the longitudinal beam 11 in supporting the photovoltaic module. Based on this, in order to achieve the above purpose while reducing the operating pressure of the operator in installing the cross beam 3 and the longitudinal beam 11, combined with Figure 7 and Figure 8 As shown, the connecting member 5 has a first mounting groove 52, a second mounting groove 53 and a third mounting groove 54 which are alternately opened in sequence up and down, so that the groove direction of the second mounting groove 53 is opposite to the groove direction of the first mounting groove 52 and the third mounting groove 54, wherein the bottom of the second mounting groove 53 is provided with a first mounting hole 501, and the bottom of the first mounting groove 52 and the third mounting groove 54 are provided with a second mounting hole 502.

[0062] When the above-mentioned connecting member 5 is used to connect the crossbeam 3 and the longitudinal beam 11, the connecting member 5 is first overlapped on the longitudinal beam 11 of the supporting frame 1 in the folded state, so that the first mounting hole 501 on the second mounting groove 53 is arranged opposite to the first through hole on the longitudinal beam 11, and the first mounting hole 501 and the first through hole are sequentially penetrated by the threaded locking member 6, and then the threaded connection is made to the nut to fix the connecting member 5; then the supporting frame 1 is opened to make it in the supporting state, and after the crossbeam 3 is moved over, the two ends of the crossbeam 3 are first inserted into the first mounting groove 52 of one connecting member 5 and the third mounting groove 54 of the other connecting member 5, respectively, and the second through hole is arranged opposite to the second mounting hole 502, and the second mounting hole 502 and the second through hole are sequentially penetrated by the threaded locking member 6, and then the threaded connection is made to the nut, thereby realizing the fixed connection between the crossbeam 3, the longitudinal beam 11 and the connecting member 5. The connecting member 5 can be integrally formed by mold casting, which can also simplify the structure, reduce the difficulty of connecting the cross beam 3 and the longitudinal beam 11, and improve the connection stability.

[0063] Furthermore, a third mounting hole is formed on the side wall of the second mounting groove 53, and correspondingly, a third through hole is formed on the side wall of the longitudinal beam 11. The threaded locking member 6 passes through the third mounting hole and the third through hole in sequence and is then threadedly connected to the nut, thereby further strengthening the connection strength between the longitudinal beam 11 and the connecting member 5 and ensuring the accuracy of the installation position of the connecting member 5 on the longitudinal beam 11.

[0064] It should be noted that the first mounting hole 501 and the second mounting hole 502 provided by the utility model are both waist-shaped holes, so that the relative connection position between the crossbeam 3 and the connecting member 5 can be flexibly adjusted, so that the crossbeam 3 can be more safely and stably arranged on the connecting member 5. In addition, there are a plurality of second mounting holes 502. For example, in the present embodiment, two second mounting holes 502 are respectively arranged on opposite sides of the first mounting hole 501. The arrangement of a plurality of second mounting holes 502 can provide more fixing points, so that the connecting member 5 can flexibly adapt to crossbeams 3 of different lengths, thereby improving its versatility, helping to reduce inventory costs and management costs, and making the installation process more flexible and simple.

[0065] Furthermore, the third mounting hole can also be a waist-shaped hole, so that the relative height between the cross beam 3 and the longitudinal beam 11 can be fine-tuned to a flush state, and the cross beam 3 can also be adjusted to a higher level according to the needs of different users, so that the cross beam 3 can abut the side end surface of the photovoltaic component to prevent the photovoltaic component from sliding.

[0067] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
