Another known fixed adjustable PV bracket includes a swing arm device fixedly connected to the main shaft, used to adjust the direction of the main shaft in conjunction with an adjusting plate on the column. The swing arm device includes a mounting part and an adjusting part, which are set at an inclined angle. Both known fixed adjustable PV brackets are complex in structure, labor-intensive to operate, and costly. Utility Model Content

[0003] The purpose of this invention is to provide a fixed adjustable photovoltaic bracket that can adjust the angle of the components according to different needs, has a simple structure, is easy to operate, and reduces production and maintenance costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a fixed adjustable photovoltaic bracket, comprising a column and a main shaft, wherein the main shaft is rotatably mounted on the column for mounting photovoltaic modules; it further comprises a limiting member, a first connecting structure and a second connecting structure, one end of the first connecting structure and the second connecting structure being respectively connected to the main shaft, the first connecting structure and the second connecting structure being set at an angle, the limiting member being fixedly connected to the column, and the ends of the first connecting structure and the second connecting structure away from the main shaft being used for fixed connection with the limiting member;

[0005] When the end of the first connecting structure away from the main shaft is fixedly connected to the limiting member, the photovoltaic module can be positioned at a preset first angle. When the end of the second connecting structure away from the main shaft is fixedly connected to the limiting member, the photovoltaic module can be positioned at a preset second angle.

[0006] As a further improvement of this utility model, the first angle is 0 degrees and the second angle is 60 degrees.

[0007] As a further improvement of this utility model, it also includes a positioning component, which is fixedly connected to the main shaft. The first connecting structure and the second connecting structure are both connected to the positioning component, thereby connecting to the main shaft.

[0008] As a further improvement of the present invention, each of the positioning components includes an upper clamp and a lower clamp. Each of the upper clamp and the lower clamp includes an arc-shaped middle portion and a flat end portion. The flat end portion is located at the left and right ends of the arc-shaped middle portion. The arc-shaped middle portions of the upper clamp and the lower clamp are fitted together on the main shaft, and the flat end portions of the upper clamp and the lower clamp are respectively fastened together by fasteners.

[0009] As a further improvement of the present invention, the lower clamp is provided with a connecting member on the side opposite to the upper clamp. The connecting member extends radially along the lower clamp and is used to fix the first connecting structure and the second connecting structure.

[0010] As a further improvement of the present invention, the connector includes a first plate and a second plate, and both the first connecting structure and the second connecting structure are clamped and fixed between the first plate and the second plate.

[0011] As a further improvement of the present invention, the positioning element includes a first positioning element and a second positioning element, wherein the first positioning element is used to be fixedly connected to the first connecting structure, and the second positioning element is used to be fixedly connected to the second connecting structure.

[0013] As a further improvement of the present invention, the limiting member includes a first limiting member and a second limiting member, which are located on opposite sides of the column respectively. The first limiting member is used to be fixedly connected to the first connecting structure, and the second limiting member is used to be fixedly connected to the second connecting structure.

[0014] As a further improvement of the present invention, each of the first limiting member and the second limiting member includes a base plate, a first mounting plate and a second mounting plate. The base plate connects the first mounting plate and the second mounting plate. The first mounting plate and the second mounting plate are located on opposite sides of the base plate. The first mounting plate is used for positioning connection with the column, and the second mounting plate is used for positioning connection with the first connecting structure or the second connecting structure.

[0015] Compared to existing technologies, this invention features two connecting structures. One end of the first connecting structure and one end of the second connecting structure are respectively connected to the main shaft, and the first and second connecting structures are angled together. This allows the photovoltaic module to be positioned at a preset first angle when the end of the first connecting structure furthest from the main shaft is fixedly connected to the limiting member, and the photovoltaic module to be positioned at a preset second angle when the end of the second connecting structure furthest from the main shaft is fixedly connected to the limiting member. Thus, the two connecting structures on both sides of the column have a clear division of labor, each driving the photovoltaic module to the required preset angle, allowing for adjustment of the module angle according to different needs. This invention has a simple structure, is easy to operate, and reduces production and maintenance costs. Attached Figure Description

In this utility model, the word "several" means two or more.

[0034] Please refer to Figures 1 to 15 As shown, this utility model discloses a fixed adjustable photovoltaic bracket 100, including... Figure 1 The column 1 extending vertically and in Figure 1 The main shaft 2 extends in the front-to-back direction. The main shaft 2 is rotatably mounted on the column 1 for mounting the photovoltaic module 200. The adjustable photovoltaic bracket 100 of this invention also includes a limiting member 4, a first connecting structure 51, and a second connecting structure 52. One end of the first connecting structure 51 and the second connecting structure 52 are respectively connected to the main shaft 2, and the first connecting structure 51 and the second connecting structure 52 are arranged at an angle. The limiting member 4 is fixedly connected to the column 1, and the ends of the first connecting structure 51 and the second connecting structure 52 away from the main shaft 2 are both used for fixed connection with the limiting member 4. Therefore, this invention achieves driving operation of the photovoltaic module 200 in two states through the connecting structures 51 and 52, with a simple structure, labor-saving operation, and reduced production and maintenance costs.

[0035] Please refer to Figures 1 to 6 When the end of the first connecting structure 51 furthest from the main shaft 2 is fixedly connected to the limiting member 4, the photovoltaic module 200 can be positioned at a preset first angle. Please refer to... Figures 7 to 12 When the end of the second connecting structure 52 furthest from the main shaft 2 is fixedly connected to the limiting member 4, the photovoltaic module 200 can be positioned at a preset second angle. For details, please refer to... Figure 6 The first angle is 0 degrees, at which point the photovoltaic module 200 is installed horizontally above the column 1. Please refer to... Figure 12 The second angle is 60 degrees, at which point the photovoltaic module 200 is installed at an angle above the column 1.

[0036] Please refer to Figures 1 to 6 And special reference Figure 6 The first angle is 0 degrees; please refer to Figures 7 to 12 And special reference Figure 12 The second angle is 60 degrees. Therefore, this invention can adjust between 0 degrees (when the photovoltaic module 200 is in a horizontal state) and 60 degrees (when the photovoltaic module 200 is in a tilted state).

[0037] Please refer to Figures 1 to 12 The adjustable photovoltaic bracket 100 of this utility model also includes a positioning element 3. The positioning element 3 is fixedly connected to the main shaft 2. Both the first connecting structure 51 and the second connecting structure 52 are connected to the positioning element 3, thereby connecting to the main shaft 2. The positioning element 3, fixedly connected to the main shaft 2, serves to fix the tops of the first connecting structure 51 and the second connecting structure 52 to the main shaft 2. To a certain extent, it can be understood that the connecting structures 51 and 52 of the adjustable photovoltaic bracket 100 of this utility model include the positioning element 3.

[0038] Please refer to Figure 5 , Figure 11 and Figure 15 The positioning component 3 includes an upper clamp 301 and a lower clamp 302. Each of the upper clamp 301 and the lower clamp 302 includes an arc-shaped middle portion 3001 and two flat end portions 3002, with the two flat end portions 3002 located at the left and right ends of the arc-shaped middle portion 3001. The arc-shaped middle portions 3001 of the upper clamp 301 and the arc-shaped middle portions 3001 of the lower clamp 302 are fitted together on the main shaft 2, and the flat end portions 3002 of the upper clamp 301 and the flat end portions 3002 of the lower clamp 302 are respectively fixedly connected as a whole by fasteners 11. This configuration ensures a fixed connection between the positioning element 3 and the main shaft 2, so that the top of the first connecting structure 51 and the top of the second connecting structure 52 of this utility model can be fixed on the main shaft 2 by the positioning element 3; and the positioning element 3 is composed of two parts, which are fixed on the main shaft 2 in a way that the upper and lower parts embrace each other, making the fixed connection between the positioning element 3 and the main shaft 2 simple and convenient.

[0039] Please refer to Figure 5 and Figure 11 The lower clamp 302 is further provided with a connector 9 on the side opposite to the upper clamp 301. The connector 9 extends radially along the lower clamp 302 and is used to fix the first connecting structure 51 and the second connecting structure 52. For example Figure 5In the embodiment of the first connecting structure 51 and the second connecting structure 52, both are push rod shaped.

[0040] Please continue to refer to this. Figure 5 and Figure 11 The longer first connecting structure 51 corresponds to the connecting member 9, which extends beyond the left end of the lower clamp 302; the shorter second connecting structure 52 corresponds to the connecting member 9, which extends beyond the right end of the lower clamp 302. In other embodiments not shown, the connecting member 9 extends beyond both the left and right ends of the lower clamp 302. This arrangement eliminates the need for a positioning member 3, allowing the longer first connecting structure 51 and the shorter second connecting structure 52 to be fixed to the same positioning member 3. In a specific embodiment, the connecting member 9 is integrally formed below the upper clamp 301; therefore, the connecting member 9 is actually part of the positioning member 3.

[0041] Please refer to Figure 4 and Figure 5 The connector 9 includes a first plate surface 91 and a second plate surface 92. The first connecting structure 51 and the second connecting structure 52 are both clamped and fixed between the first plate surface 91 and the second plate surface 92. The clamping and fixing method can ensure the pre-installation between the two connecting structures 51, 52 and the positioning member 3. In a specific embodiment, after clamping, welding or fasteners 11 are required for fixing, thereby ensuring the installation stability of the two connecting structures 51, 52 on the positioning member 3 and ensuring the pushing effect of the two connecting structures 51, 52 on the positioning member 3 and the main shaft 2.

[0042] Please refer to Figure 5 and Figure 11 The positioning element 3 includes a first positioning element 31 and a second positioning element 32. The first positioning element 31 is used to be fixedly connected to the first connecting structure 51, and the second positioning element 32 is used to be fixedly connected to the second connecting structure 52. That is, the first connecting structure 51 and the second connecting structure 52 each need to be fixed to the main shaft 2 by one of the positioning elements 3 in order to drive or push the main shaft 2 to rotate.

[0043] Please refer to Figure 5 and Figure 11The adjustable photovoltaic bracket 100 of this utility model also includes a bearing seat 6 and a top seat 7. The top seat 7 is fixed to the top of the column 1, and the bearing seat 6 is fixed to the top of the top seat 7, which is equivalent to the bearing seat 6 being fixed to the top of the column 1. The main shaft 2 passes through the bearing seat 6. The first positioning member 31 and the second positioning member 32 are respectively located on opposite sides of the bearing seat 6. With this arrangement, the first connecting structure 51 and the second connecting structure 52 are also located on opposite sides of the bearing seat 6 to ensure ease of operation. The bearing seat 6 is provided with a bearing, which is limited between the bearing seat 6 and the main shaft 2 to ensure smooth rotation of the main shaft 2 above the column 1. Under normal circumstances, the top seat 7 is used to connect and fix the bearing seat 6 and the column 1. In special cases, the top seat 7 may not be used.

[0044] Please refer to Figures 1 to 14 The adjustable photovoltaic bracket 100 of this utility model also includes a base 8. The base 8 serves to fix the column 1 on top of it. Therefore, in a specific embodiment, the column 1 is located between the top seat 7 and the base 8.

[0045] Please refer to Figures 1 to 11 The positioning element 3 consists of two parts, which are located on opposite sides of the bearing seat 6 (e.g., Figure 5 The limiting members 4 are two in number and are located on opposite sides of the column 1 (e.g., the front and rear sides of the column). Figure 5 The first connecting structure 51 and the second connecting structure 52 both include an upper end and a lower end. The upper end of the first connecting structure 51 can be fixed to one of the positioning members 3 (e.g., the front positioning member 3) by a fastener 11. The upper end of the second connecting structure 52 can be fixed to the other positioning member 3 (e.g., the rear positioning member 3) by a fastener 11. The lower end of the first connecting structure 51 can be fixed to one of the limiting members 4 (e.g., the front limiting member 4) by a fastener 11. The lower end of the second connecting structure 52 can be fixed to the other limiting member 4 (e.g., the rear limiting member 4) by a fastener 11. The two connecting structures 5 (the first connecting structure 51 and the second connecting structure 52) on opposite sides of the column 1 have clearly defined functions, each responsible for one state.

[0046] Corresponding to the first positioning member 31 and the second positioning member 32 being located on opposite sides of the bearing seat 6, the limiting member 4 includes a first limiting member 41 and a second limiting member 42. The first limiting member 41 and the second limiting member 42 are located on opposite sides of the column 1. The first limiting member 41 is used for fixed connection with the first connecting structure 51, and the second limiting member 42 is used for fixed connection with the second connecting structure 52. That is, the first limiting member 41, which fixes the lower end of the first connecting structure 51, and the second limiting member 42, which fixes the lower end of the second connecting structure 52, are also located on opposite sides of the bearing seat 6, again to meet the need for ease of operation.

[0047] Please refer to Figure 4 and Figure 5 Each of the limiting members 4 (the first limiting member 41 and the second limiting member 42) includes a base plate 40, a first mounting plate 401, and a second mounting plate 402. The base plate 40 connects the first mounting plate 401 and the second mounting plate 402, which are located on opposite sides of the base plate 40. The first mounting plate 401 is used for positioning connection with the column 1, and the second mounting plate 402 is used for positioning connection with the lower end of the first connecting structure 51 or the second connecting structure 52.

[0048] Please refer to Figure 5 In this invention, the positioning member 3 and the limiting member 4 may further include a reinforcing plate 10. The reinforcing plate 10 is connected between the first plate surface 91 and the second plate surface 92 and / or between the substrate 40 and the first mounting plate 401 and / or between the substrate 40 and the second mounting plate 402. The reinforcing plate 10 serves to strengthen the positioning member 3 and the limiting member 4. The strengthening of the positioning member 3 by the reinforcing plate 10 actually strengthens the connecting member 9 at the bottom of the positioning member 3.

[0049] It should be noted that the first connecting structure 51 and the second connecting structure 52 can be either fixedly connected to two of the positioning members 3 or jointly fixedly connected to the same positioning member 3; and / or, the first connecting structure 51 and the second connecting structure 52 can be either fixedly connected to two of the limiting members 4 or jointly fixedly connected to the same limiting member 4. That is, the number of positioning members 3 and limiting members 4 used to fix the first connecting structure 51 and the second connecting structure 52 is not limited, as long as the first connecting structure 51 and the second connecting structure 52 do not work simultaneously.

[0050] It should also be noted that the lengths of the first connecting structure 51 and the second connecting structure 52 may be the same or different. Please refer to [reference needed] for details. Figure 4 and Figure 10 When the lengths of the first connecting structure 51 and the second connecting structure 52 are different, the installation heights of the two limiting members 4 on the column 1 are different. The limiting member 4 corresponding to the longer first connecting structure 51 is installed at a lower height on the column 1, and the limiting member 4 corresponding to the shorter second connecting structure 52 is installed at a higher height on the column 1 to ensure the photovoltaic module 200 can switch between the first angle and the second angle. Therefore, this invention needs to ensure that the two connecting structures 51 and 52 each correspond to a module angle, and that the other connecting structure 51 / 52 is not working when one of them is working; the longer first connecting structure 51 can act as a handle, which is labor-saving, simple to operate, and low in cost.

[0051] Apart from Figure 2 , Figure 4 , Figure 8 and Figure 10 In the case of a column 1 with a connecting structure 5 tightly arranged on each of its opposite sides, this utility model can also arrange two connecting structures 51 and 52 between two adjacent columns 1. Please refer to the following for details. Figure 13 and Figure 14 Even if the two connection structures 51 and 52 are far apart, it will not affect the operation of the drive.

[0052] The working principle of this invention is as follows: By adjusting the first connecting structure 51 in the connecting structure 5 to an idle state and the second connecting structure 52 to an active state, the second connecting structure 52 can adjust and maintain the component angle at 60 degrees. In some project sites with poor terrain but good solar radiation resources, this invention can be used to fix the adjustable photovoltaic bracket 100 and place the component at 60 degrees to obtain more power generation. Adjusting the component's orientation according to the season—whether it faces east or west—simply involves disassembling the second connecting structure 52 and installing it on the other side, saving on electrical control costs and obtaining more power generation. According to the weather station, a strong wind warning is received in advance. The photovoltaic module 200 needs to be laid flat. Simply adjust the second connection structure 52 to the idle state and the first connection structure 51 to the working state to lay the photovoltaic module 200 flat to 0 degrees, so as to reduce the impact of the strong wind on the fixed adjustable photovoltaic bracket 100 and the photovoltaic module 200 on it. After the strong wind passes, the photovoltaic module 200 can be adjusted again to the preset tilt angle of 60 degrees through the second connection structure 52, so that the photovoltaic module 200 can continue to work in a way that can obtain more power generation.

[0053] Therefore, this utility model realizes the driving operation of the photovoltaic module 200 in two states through two connection structures 51 and 52. The structure is simple, the operation is labor-saving, and the production and maintenance costs are reduced.

[0054] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. The understanding of the present utility model should be based on those skilled in the art. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present utility model. All technical solutions and improvements that do not depart from the spirit and scope of the present utility model should be covered within the scope of the claims of the present utility model.
