Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic panel installation, in particular to a photovoltaic panel fixing device for a building exterior wall. Background Art

[0002] When photovoltaic panels are installed on the exterior wall, bolts are usually embedded in the exterior wall, and then the photovoltaic bracket is installed by putting it on the embedded bolts and tightening the nuts. Since the photovoltaic panels are pre-installed on the photovoltaic bracket, the operating space between the photovoltaic panels and the exterior wall is small, and it is time-consuming and labor-intensive to align the bolts with the holes and tighten the nuts. Therefore, we proposed a photovoltaic panel fixing device for the exterior wall of a building, which combines the embedded parts pre-installed on the exterior wall with the housing installed on the photovoltaic panel to achieve plug-in installation and improve the installation efficiency of the photovoltaic panels. Utility Model Content

[0003] The purpose of this utility model is to provide a photovoltaic panel fixing device for a building exterior wall, which has the advantages of matching the embedded parts pre-installed on the exterior wall with the shell installed on the photovoltaic panel to achieve plug-in installation and improve the installation efficiency of the photovoltaic panel, so as to solve the above-mentioned background technical problems.

[0004] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: A photovoltaic panel fixing device for a building exterior wall, comprising a plurality of mounting plates fixedly installed on the wall by expansion bolts and a mounting frame installed on one side of the photovoltaic panel body, a fixing block fixedly connected to one side of the mounting plate, a rectangular groove being provided on the top of the fixing block, a wedge-shaped block being slidably connected to the inner cavity of the rectangular groove, two symmetrical springs being fixedly connected to the bottom of the wedge-shaped block, the bottom of the spring being fixedly connected to the inner wall of the rectangular groove, a sleeve block being sleeved on the surface of the fixing block, two bolts being penetrated on one side of the sleeve block, the sleeve block being fixedly installed on the fixing block by the two bolts, and a slot being provided on the top of the sleeve block for engaging with the wedge-shaped block.

[0005] Preferably, a groove is provided on one side of the fixing block, and two symmetrical limiting rods are fixedly connected to the bottom of the wedge-shaped clamping block, and the spring is sleeved on the surface of the limiting rods.

[0006] Preferably, the bottom of the limiting rod passes through the inner cavity of the trough body and is threadedly connected with a washer nut on the surface.

[0007] Preferably, a wedge-shaped surface adapted to the wedge-shaped clamping block is provided on the top of the inner cavity of the sleeve block.

[0008] Preferably, two symmetrical guide bars are fixedly connected to the bottom of the inner cavity of the sleeve block, and two guide grooves adapted to the guide bars are provided on the bottom of the fixed block.

[0009] The beneficial effects of the utility model are:

[0010] 1. The utility model installs the mounting plate on the exterior wall through expansion bolts, and then installs the sleeve block on the installation frame through bolts. The photovoltaic panel body is picked up so that the sleeve block is sleeved on the fixed block. During this period, the sleeve block causes the wedge-shaped card block to move downward and squeeze the spring until the sleeve block is completely sleeved on the surface of the fixed block. At this time, the card slot is larger than the wedge-shaped card block and is aligned. The wedge-shaped card block extends into the inner cavity of the card slot due to the elastic force of the spring, limiting the sleeve block so that the sleeve block is installed on the surface of the fixed block, thereby realizing the installation of the photovoltaic panel body. It can achieve the purpose of matching the embedded parts pre-installed on the exterior wall with the sleeve shell installed on the photovoltaic panel to realize plug-in installation and improve the installation efficiency of the photovoltaic panel.

[0011] 2. The utility model provides a wedge-shaped surface. When the sleeve is sleeved on the surface of the fixed block, the wedge-shaped surface will first contact the wedge-shaped surface of the wedge-shaped clamping block, ensuring the smoothness of the sleeve on the surface of the fixed block.

[0012] 3. The utility model uses the guide strips and the guide grooves in conjunction with each other. When the sleeve block is sleeved on the surface of the fixed block, the guide strips on the sleeve block will first enter the inner cavity of the guide groove, limiting the movement direction of the sleeve block and ensuring that the sleeve block can be stably sleeved on the surface of the fixed block.

A fixing block 4 is fixedly connected to one side of the mounting plate 1. A rectangular groove 5 is provided on the top of the fixing block 4. A wedge-shaped block 6 is slidably connected to the inner cavity of the rectangular groove 5. Two symmetrical springs 7 are fixedly connected to the bottom of the wedge-shaped block 6. A groove body 11 is provided on one side of the fixing block 4. Two symmetrical limiting rods 12 are fixedly connected to the bottom of the wedge-shaped block 6. The spring 7 is sleeved on the surface of the limiting rod 12. The bottom of the limiting rod 12 passes through the inner cavity of the groove body 11 and is threadedly connected to a gasket nut 13 on the surface. The bottom of the spring 7 is fixedly connected to the inner wall of the rectangular groove 5. A sleeve block 8 is sleeved on the surface of the fixing block 4. The bottom of the inner cavity of the sleeve block 8 is fixedly connected to two symmetrical The guide bar 15 and the bottom of the fixed block 4 are provided with two guide grooves 16 that are compatible with the guide bar 15. Through the cooperation of the guide bar 15 and the guide groove 16, when the sleeve block 8 is sleeved on the surface of the fixed block 4, the guide bar 15 on the sleeve block 8 will first enter the inner cavity of the guide groove 16, limiting the movement direction of the sleeve block 8 and ensuring that the sleeve block 8 can be stably sleeved on the surface of the fixed block 4. Two bolts 9 are provided on one side of the sleeve block 8. The top of the inner cavity of the sleeve block 8 is provided with a wedge-shaped surface 14 that is compatible with the wedge-shaped block 6. Through the setting of the wedge surface 14, when the sleeve block 8 is sleeved on the surface of the fixed block 4, the wedge surface 14 will first contact the wedge surface of the wedge-shaped block 6, ensuring the smoothness of the sleeve block 8 on the surface of the fixed block 4. The sleeve block 8 is fixedly installed on the fixed block 4 by two bolts 9. The top of the sleeve block 8 is provided with a card groove 10 that engages with the wedge-shaped block 6.

[0022] Working principle: When the present invention is used, the user embeds expansion bolts on the outer wall and installs the mounting plate 1 according to the distance between multiple sleeve blocks 8 installed on the mounting frame 3, picks up the photovoltaic panel body 2, and makes the sleeve block 8 sleeve on the fixed block 4. During this period, the guide bar 15 enters the inner cavity of the guide groove 16, and the wedge-shaped surface 14 above the inner cavity of the sleeve block 8 contacts the wedge-shaped block 6, which will drive the wedge-shaped block 6 to move downward and squeeze the spring 7 until the sleeve block 8 is completely sleeved on the surface of the fixed block 4, and the wedge-shaped block 6 is aligned with the slot 10. The elastic force of the spring 7 makes the wedge-shaped block 6 enter the inner cavity of the slot 10, restricting the sleeve block 8 to the surface of the fixed block 4, thereby realizing the installation of the photovoltaic panel body 2. During this period, the spring 7 drives the wedge-shaped block 6 to move upward, which will drive the limit rod 12 to move upward, and the gasket nut 13 provides a limit for the wedge-shaped block 6, preventing the wedge-shaped block 6 from escaping from the inner cavity of the rectangular groove 5.

[0023] To sum up: the photovoltaic panel fixing device on the exterior wall of the building installs the mounting plate 1 on the exterior wall through expansion bolts, and then installs the sleeve block 8 on the mounting frame 3 through bolts 9, picks up the photovoltaic panel body 2, and makes the sleeve block 8 be sleeved on the fixing block 4. During this period, the sleeve block 8 makes the wedge-shaped block 6 move downward and squeezes the spring 7 until the sleeve block 8 is completely sleeved on the surface of the fixing block 4. At this time, the slot 10 is larger than the wedge-shaped block 6 and is aligned. The wedge-shaped block 6 extends into the inner cavity of the slot 10 due to the elastic force of the spring 7, limiting the sleeve block 8 so that the sleeve block 8 is installed on the surface of the fixing block 4, thereby realizing the installation of the photovoltaic panel body 2, and achieving the purpose of matching the embedded parts pre-installed on the exterior wall with the sleeve installed on the photovoltaic panel to realize plug-in installation and improve the installation efficiency of the photovoltaic panel.
