Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module installation technology, and in particular relates to a vertical photovoltaic module installation structure. Background Technology

[0002] Conventional photovoltaic modules are installed with fixed tilt brackets, forming an installation structure with two rows of brackets. The tilt angle is changed by adjusting the height of the brackets. At the same time, in order to maximize the annual power generation data, the modules are normally installed at a 0° azimuth angle (due south). The tilt angle is greatly affected by latitude and altitude. With the promotion of time-of-use pricing in the market, the electricity price is lower during the period with the highest power generation at noon. During other periods with high electricity prices, the power generation is not high due to the incident angle, which ultimately affects the power generation revenue. Therefore, the solution of vertically installing modules has emerged.

[0003] Most existing vertical installation solutions use a slot-type design, where the frame of the photovoltaic module is directly inserted into the slot of the bracket and then fixed. However, if the bracket slot is too wide, it will obstruct the module and have a significant impact on power generation. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical photovoltaic module installation structure to solve the problems in the prior art. The specific technical solution is as follows:

[0005] A vertical photovoltaic module mounting structure includes two parallel horizontal frames and two parallel vertical frames. The two horizontal frames are installed at the top and bottom ends of the photovoltaic laminate, and the two vertical frames are installed at the left and right ends of the photovoltaic laminate. The two vertical frames are fixedly installed to two vertical brackets by two sets of bolts.

[0006] Furthermore, the horizontal frame includes a B-side structure, with an A-side structure and a U-shaped structure at its upper and lower ends, respectively.

[0007] Furthermore, the upper ends of the B-side structure one and the U-shaped structure one form a groove one, and the upper or lower end of the photovoltaic laminate is engaged in the groove one.

[0008] Furthermore, the vertical frame includes a second B-side structure, with a second A-side structure and a second U-shaped structure at its upper and lower ends, respectively.

[0009] Furthermore, the upper ends of the second A-side structure, the second B-side structure, and the second U-shaped structure form a second groove, and the left or right end of the photovoltaic laminate is engaged in the second groove.

[0010] Furthermore, the lower ends of the B-side structure two and the U-shaped structure two, and the C-side structure form a groove three. The vertical bracket is snapped into the groove three, and the bolt end passes through the mounting holes provided on the vertical bracket and the B-side structure two, and is locked with the nut.

[0011] Furthermore, the length of surface A structure one is shorter than the length of the upper end of surface U structure one, the length of surface A structure two is shorter than the length of surface C structure, and the length of surface B structure two is longer than the length of surface B structure one.

[0012] Furthermore, the vertical support has an inverted I-shaped metal profile, including a horizontal frame, with longitudinal frames fixed at both ends of the horizontal frame. The curved portions at both ends of the longitudinal frames are parallel to the horizontal frame, and the curved portions are inserted into the groove three. The C-surface structure is inserted between the curved portions and the horizontal frame.

[0013] Furthermore, the curved portions at both ends of the longitudinal frame are provided with bolt through holes, and the bolt ends pass through the bolt through holes and the mounting holes provided on the second structure of surface B, and are locked with nuts.

[0014] Furthermore, the lower end of the vertical support is fixed inside the concrete pile foundation, which is pre-embedded below the ground.

[0015] The advantages of this utility model are:

[0016] 1. Significantly reduced shading: By shortening the horizontal and vertical borders, and with the vertical borders plugged into the vertical brackets, the shading area on the back of the photovoltaic modules is reduced by more than 4.9% compared to traditional full-coverage slot brackets. This directly improves the overall power generation efficiency of the photovoltaic modules throughout the day, especially in the early morning and evening, which helps to increase the revenue from power generation under time-of-use pricing.

[0017] 2. Stable and reliable structure: The inverted I-shaped vertical support provides strong support, and the bolted connection ensures wind load resistance, resulting in high overall structural stability.

[0018] 3. Reduced costs: The simplified bracket and frame structure, along with the elimination of additional clamping blocks and other accessories, reduces the system's material costs. Attached Figure Description

[0034] Example 1

[0035] like Figures 1-11As shown, a vertical photovoltaic module installation structure includes two parallel horizontal frames 2 and two parallel vertical frames 3. The two horizontal frames 2 are installed at the upper and lower ends of the photovoltaic laminate 1, and the two vertical frames 3 are installed at the left and right ends of the photovoltaic laminate 1. The two vertical frames 3 are respectively fixed to two vertical brackets 4 by two sets of bolts 7.

[0036] The working principle of the above technical solution is as follows: two horizontal frames 2 are installed at the top and bottom ends of the photovoltaic laminate 1, and two vertical frames 3 are installed at the left and right ends of the photovoltaic laminate 1 to complete the assembly of the photovoltaic module. The two vertical frames 3 are fixed to the two vertical brackets 4 respectively by two sets of bolts 7, thereby completing the installation and fixation of the photovoltaic module and the vertical brackets 4. By shortening the horizontal frames 2 and the vertical frames 3, and inserting the vertical frames 3 into the vertical brackets 4, compared with the traditional full-coverage slot bracket, the shading area on the back of the photovoltaic module is reduced by more than 4.9%, thereby directly improving the power generation efficiency of the photovoltaic module throughout the day, especially in the morning and evening, which is conducive to improving the power generation revenue under the time-of-use electricity price.

[0037] Example 2

[0038] like Figures 1-11 As shown, the horizontal frame 2 includes a B-side structure 202, and the upper and lower ends of the B-side structure 202 are respectively provided with an A-side structure 201 and a U-shaped structure 203.

[0039] The upper ends of the B-side structure 202 and the U-shaped structure 203 form a groove, and the upper or lower end of the photovoltaic laminate 1 is engaged in the groove.

[0040] The working principle of the above technical solution is as follows: There is no C-side structure 304 on the horizontal frame 2, and the length of the B-side structure 202 is relatively short, which simplifies the frame structure and eliminates the need for additional pressure blocks and other accessories, thereby reducing the system material cost.

[0041] Example 3

[0042] like Figures 1-11 As shown, the vertical frame 3 includes a B-side structure 302, and the upper and lower ends of the B-side structure 302 are respectively provided with an A-side structure 301 and a U-shaped structure 303.

[0043] The upper ends of the A-side structure 2 301, the B-side structure 2 302 and the U-shaped structure 2 303 form a groove 2, and the left or right end of the photovoltaic laminate 1 is snapped into the groove 2.

[0044] The lower ends of the B-side structure 302, the U-shaped structure 303, and the C-side structure 304 form a groove 3. The vertical bracket 4 is snapped into the groove 3. The end of the bolt 7 passes through the mounting holes 305 provided on the vertical bracket 4 and the B-side structure 302 and is locked with the nut.

[0045] The working principle of the above technical solution is as follows: by setting groove two and groove three, the stability of the connection between photovoltaic laminate 1, longitudinal frame 3 and vertical support 4 is ensured, and then the stability between photovoltaic laminate 1, longitudinal frame 3 and vertical support 4 is further ensured by fixing with bolt 7.

[0046] The vertical bracket 4 is installed in the groove 3 to prevent the vertical bracket 4 from being directly installed and fixed to the photovoltaic laminate 1, thereby reducing the shading of the photovoltaic laminate 1 and directly improving the power generation efficiency of the photovoltaic module.

[0047] Example 4

[0048] like Figures 1-11 As shown, the length of surface A structure 201 is shorter than the length of the upper end of surface U structure 203, the length of surface A structure 301 is shorter than the length of surface C structure 304, and the length of surface B structure 302 is longer than the length of surface B structure 202.

[0049] The working principle of the above technical solution is as follows: The shortened design of A-side structure 1 201 and A-side structure 2 301 reduces the shading area on the back of the photovoltaic module by more than 4.9% compared with the traditional full-coverage slot bracket, thereby directly improving the power generation efficiency of the photovoltaic module, especially in the morning and evening, which makes it easier to increase the power generation revenue under the time-of-use electricity price.

[0050] Example 5

[0051] like Figures 1-11 As shown, the vertical support 4 is a metal profile with an inverted I-shaped cross section, including a horizontal frame 401. Both ends of the horizontal frame 401 are fixed with vertical frames 402. The bent portions at both ends of the vertical frames 402 are parallel to the horizontal frame 401. The bent portions are inserted into the groove three. The C-surface structure 304 is inserted between the bent portions and the horizontal frame 401.

[0052] The curved portions at both ends of the longitudinal frame 402 are provided with bolt through holes 403. The ends of the bolts 7 pass through the bolt through holes 403 and the mounting holes 305 provided on the B-side structure 302, and are locked with nuts.

[0053] The lower end of the vertical support 4 is fixed inside the concrete pile foundation 6, which is pre-embedded below the ground 5.

[0054] The working principle of the above technical solution is as follows: the metal profile with an inverted I-shaped cross section has high rigidity and strength. The vertical bracket 4 can be installed with the four longitudinal frame 3, which has strong adaptability and is suitable for use in different scenarios.

[0055] The vertical bracket 4 has bolt through holes 403 at certain intervals along the I-shaped section, which are used to pass through bolts 7. It can be combined with the B-side structure 302 of the longitudinal frame 3 for reinforcement installation.

[0056] The specific installation steps are as follows:

[0057] S1. Install two horizontal frame 2 at the top and bottom ends of the photovoltaic laminate 1, and install two vertical frame 3 at the left and right ends of the photovoltaic laminate 1 to complete the assembly of the photovoltaic module;

[0058] S2. Combine the vertical support 4 with the concrete pile foundation 6 to form a fixed structure, and arrange multiple fixed structures at intervals according to the actual installation distance.

[0059] S3. The photovoltaic module is installed by snapping it onto the vertical bracket through the longitudinal frame 3, and then fastened with bolts 7.
