Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic curtain wall technology, and more specifically, to an energy-saving building photovoltaic curtain wall with high light energy utilization rate. Background Technology
[0002] Photovoltaic curtain walls are an innovative architectural design that combines photovoltaic power generation technology with building facades. By integrating solar photovoltaic panels onto the exterior of a building, it not only enhances the building's aesthetics but also effectively utilizes solar energy for power generation, improving the building's solar energy utilization rate and achieving energy conservation and environmental protection. To achieve mass installation, existing photovoltaic curtain walls typically employ a unitized installation structure, where multiple photovoltaic curtain wall panels are pre-installed onto an aluminum alloy frame, and then the entire structure is installed on the building facade. However, when installing multiple photovoltaic curtain wall panels onto the aluminum alloy frame, bolts are mostly used to fix the photovoltaic curtain wall to the aluminum alloy frame, making the operation relatively complex. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an energy-saving building photovoltaic curtain wall with high light energy utilization rate and the advantages of simple and convenient operation.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving building photovoltaic curtain wall with high light energy utilization rate, comprising an aluminum alloy frame, a support frame fixedly installed in the inner cavity of the aluminum alloy frame, a photovoltaic power generation module placed on the front side of the support frame, a fixing frame fixedly installed on the front side of the aluminum alloy frame, a pressure frame inserted into the inner cavity of the fixing frame, a lock hole opened at the top of both the aluminum alloy frame and the pressure frame, a locking pin inserted into the inner cavity of the lock hole, mounting bolts inserted at the four corners of the pressure frame, columns provided at the left and right ends of the rear side of the aluminum alloy frame, mounting plates welded to the upper and lower ends of the rear side of the columns, and fixing nuts fixedly installed in the inner cavity of the columns.
[0005] As a preferred embodiment of this utility model, the cross-sectional shape of the fixing frame is "L" shaped, and the overall shape of the fixing frame is "U" shaped.
[0006] In a preferred embodiment of this utility model, the pressure frame is inserted into the fixed frame, and a rubber strip is fixedly installed on the rear side of the fixed frame, the rubber strip being in contact with the photovoltaic power generation module.
[0007] As a preferred embodiment of this utility model, the lock hole on the pressure frame penetrates the pressure frame, while the lock hole on the aluminum alloy frame does not penetrate the aluminum alloy frame, and the front side of the locking pin and the front side of the pressure frame are on the same vertical plane.
[0008] As a preferred embodiment of this utility model, the mounting bolt passes through the pressure frame, the aluminum alloy frame and the column from front to back, and the rear end of the mounting bolt is engaged in the fixing nut.
[0009] As a preferred embodiment of this utility model, an adjusting nut is fixedly installed at the rear end of the inner cavity of the column, and a stud is engaged in the inner cavity of the adjusting nut.
[0010] In a preferred embodiment of this invention, the adjusting nut is located inside the fixed nut, and the length of the adjusting nut is equal to half the length of the fixed nut.
[0011] As a preferred embodiment of this utility model, the stud has an adjustment hole at its front end, and the adjustment hole is a regular hexagon.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model installs a fixed frame on an aluminum alloy frame. After the photovoltaic power generation module is placed on the support frame, the pressure frame is slidably inserted into the fixed frame. The left and right sides of the pressure frame press down on the photovoltaic power generation module, thereby realizing the installation of the photovoltaic power generation module and the aluminum alloy frame. The entire installation process does not require the use of bolts to install each photovoltaic power generation module individually, and the overall operation is simple and convenient.
[0014] 2. This utility model, by setting an adjusting nut inside the fixed nut, prevents the mounting bolt from rotating further after it contacts the front end of the stud when the mounting bolt is screwed in. This avoids excessive stress around the fixing position of the mounting bolt due to excessive tightening torque. Furthermore, the adjusting hole can be rotated using a hex wrench to accommodate mounting bolts of different lengths and specifications. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 6 As shown, this utility model provides an energy-saving building photovoltaic curtain wall with high light energy utilization rate, including an aluminum alloy frame 1, a support frame 2 fixedly installed in the inner cavity of the aluminum alloy frame 1, a photovoltaic power generation module 3 placed on the front side of the support frame 2, a fixing frame 4 fixedly installed on the front side of the aluminum alloy frame 1, a pressure frame 14 inserted into the inner cavity of the fixing frame 4, a lock hole 5 opened at the top of both the aluminum alloy frame 1 and the pressure frame 14, a locking pin 6 inserted into the inner cavity of the lock hole 5, mounting bolts 7 inserted at the four corners of the pressure frame 14, columns 8 provided at the left and right ends of the rear side of the aluminum alloy frame 1, mounting plates 9 welded to the upper and lower ends of the rear side of the columns 8, and fixing nuts 10 fixedly installed in the inner cavity of the columns 8.
[0024] By installing a fixing frame 4 on the aluminum alloy frame 1, after placing the photovoltaic power generation module 3 on the support frame 2, the pressure frame 14 is slidably inserted into the fixing frame 4. The left and right sides of the pressure frame 14 press down on the photovoltaic power generation module 3, thereby realizing the installation of the photovoltaic power generation module 3 and the aluminum alloy frame 1. The entire installation process does not require the use of bolts to install each photovoltaic power generation module 3 individually, and the overall operation is simple and convenient.
[0025] Among them, the cross-sectional shape of the fixed frame 4 is "L" shaped, and the overall shape of the fixed frame 4 is "U" shaped;
[0026] The L-shaped fixing frame 4 can limit the pressure frame 14 in the front and rear directions, while the overall U-shaped fixing frame 4 can limit the bottom of the pressure frame 14.
[0027] Among them, the pressure frame 14 is inserted into the fixed frame 4, and a rubber strip is fixedly installed on the rear side of the fixed frame 4. The rubber strip is in contact with the photovoltaic power generation module 3.
[0028] The use of rubber strips reduces friction on the photovoltaic module 3 when the pressure frame 14 is inserted, thus preventing damage to the photovoltaic module 3.
[0029] Among them, the lock hole 5 located on the pressure frame 14 penetrates the pressure frame 14, the lock hole 5 located on the aluminum alloy frame 1 does not penetrate the aluminum alloy frame 1, and the front side of the locking pin 6 and the front side of the pressure frame 14 are on the same vertical plane.
[0030] The design that the keyhole 5 does not penetrate the aluminum alloy frame 1 can prevent the locking pin 6 from being inserted too far and causing it to separate from the pressure frame 14.
[0031] Among them, the mounting bolt 7 passes through the pressure frame 14, the aluminum alloy frame 1 and the column 8 from front to back, and the rear end of the mounting bolt 7 is engaged in the fixing nut 10.
[0032] When installing on the exterior facade, simply fix the mounting bolts 7 at the four corners of the pressure frame 14 to achieve installation.
[0033] Among them, an adjusting nut 11 is fixedly installed at the rear end of the inner cavity of the column 8, and a stud 12 is engaged in the inner cavity of the adjusting nut 11.
[0034] By setting an adjusting nut 11 inside the fixing nut 10, when the mounting bolt 7 is screwed in, after the mounting bolt 7 contacts the front end of the stud 12, the mounting bolt 7 cannot continue to rotate. This avoids the situation where the stress around the fixing position of the mounting bolt 7 is too large due to excessive tightening torque. Furthermore, the adjusting hole 13 can be rotated by using a hex wrench to accommodate mounting bolts 7 of different lengths and specifications.
[0035] The adjusting nut 11 is located inside the fixed nut 10, and the length of the adjusting nut 11 is equal to half the length of the fixed nut 10.
[0036] Ensure that the mounting bolt 7 can make stable contact with the front end of the stud 12 when it is screwed in.
[0037] The stud 12 has an adjustment hole 13 at its front end, and the adjustment hole 13 is a regular hexagon.
[0038] The adjusting nut 11, stud 12 and fixing nut 10 are all threaded. The threads on the adjusting nut 11 and stud 12 rotate in the same direction, while the threads on the fixing nut 10 and adjusting nut 11 rotate in opposite directions. This avoids the situation where the rotation of the mounting bolt 7 causes the stud 12 to rotate when the mounting bolt 7 is screwed in. Furthermore, the number of rotations of the stud 12 can be easily adjusted by setting the adjusting hole 13.
[0039] Working principle and usage process of this utility model:
[0040] During pre-installation, place the aluminum alloy frame 1 on the ground, and then place the three photovoltaic power generation modules 3 into the support frame 2 from top to bottom. The support frame 2 supports the photovoltaic power generation modules 3. Then, connect the wiring of the three photovoltaic power generation modules 3 in series. Then, insert the pressure frame 14 into the fixing frame 4 from top to bottom until it is in place. After that, align the two locking holes 5 on the aluminum alloy frame 1 and the pressure frame 14, and then insert the locking pin 6 into the locking hole 5 to fix the aluminum alloy frame 1 and the pressure frame 14.
[0041] When installing on the building facade, the mounting plate 9 is first installed on the facade with bolts to fix the column 8. Then, the pre-installed aluminum alloy frame 1 is hoisted to the installation position and the aluminum alloy frame 1 is fixed to the column 8 with the mounting bolts 7.
