Description

Technical Field

[0001] The present invention belongs to the field of photovoltaic technology, and specifically discloses a detachable photovoltaic sound barrier device and an installation method thereof. Background Art

[0002] At present, the installation of photovoltaic modules on existing sound barrier equipment mainly adopts the method of first arranging and installing purlins, and then directly sticking lightweight flexible photovoltaic modules on site with structural adhesive, which has the following disadvantages: 1. When the existing sound barrier equipment (the base sound insulation material is generally a polymer light-collecting material with a 10-year warranty) is damaged or exceeds the service life and needs to be replaced, and the photovoltaic modules on it can still be used, since the photovoltaic modules cannot be disassembled, they can only be scrapped together with the sound barrier equipment, resulting in property losses; 2. When installing lightweight flexible photovoltaic modules on the top of the existing sound barrier equipment, it is generally necessary to first install the guide rails on the steel structure of the sound barrier equipment, and then install the purlins on the guide rails. After the purlins are installed, use structural adhesive to fix them. Lightweight flexible photovoltaic modules are pasted on the installation purlins. Since it is impossible to drill holes or weld directly on the steel structure of the existing sound barrier, the original installation bolts must be removed before the guide rails are installed on the original holes. This operation requires traffic control on the construction section, and the setting of hanging baskets, lifting vehicles or articulated arm vehicles to cooperate with the construction inside and outside the sound barrier ceiling. The construction is difficult, the entire installation process is complicated and the construction period is long. The photovoltaic modules are still not removable and cannot be used a second time. 3. It is necessary to apply structural adhesive on site to paste the photovoltaic modules. When the gluing environment (temperature, humidity, etc.) is limited, the bonding strength of the structural adhesive will be greatly reduced, and the safety of the photovoltaic modules cannot be guaranteed at this time. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a detachable photovoltaic sound barrier device, which is not only easy to install, but also can be disassembled without loss and reused when the existing sound barrier equipment is damaged or exceeds its service life and needs to be replaced.

[0004] In order to solve the above technical problems, the present invention provides a detachable photovoltaic sound barrier device, comprising:

[0005] A sound barrier device, the sound barrier device comprising a mounting frame, the top outer steel structure surface of the mounting frame being welded with studs;

[0006] A photovoltaic module, wherein the photovoltaic module comprises a photovoltaic body and a connecting frame, and the photovoltaic body is pasted on the connecting frame;

[0007] A guide rail, wherein the guide rail is mounted on the mounting frame via studs;

[0008] The connecting assembly comprises a locking nut, a pressing block and a fastening bolt. The photovoltaic assembly is installed on the guide rail through the locking nut, the pressing block and the fastening bolt.

[0009] As a further description of the above technical solution, both end heads of the connecting frame are provided with extension parts, and the pressing blocks are pressed on the extension parts of two adjacent connecting frames.

[0010] As a further description of the above technical solution, the guide rail has a first half and a second half that are symmetrical and integrally formed, with a distance between the first half and the second half, and the upper ends of the first half and the second half are both inverted U-shaped and have free arms.

[0011] As a further description of the above technical solution, the fastening bolt passes through the pressure block and extends into the spacing of the guide rail, and is locked and fixed by a locking nut.

[0012] As a further description of the above technical solution, the locking nut abuts against two free arms of the guide rail.

[0013] As a further description of the above technical solution, the locking nut is a plastic wing nut.

[0014] In order to solve the above technical problems, the present invention also provides a method for installing a detachable photovoltaic sound barrier device, which is to install a detachable photovoltaic module on an existing sound barrier, comprising the following steps:

[0015] (1) Welding studs: Weld studs on the top steel structure surface of the existing sound barrier equipment installation frame;

[0016] (2) Install the guide rail: Use studs to fix the guide rail to the mounting frame;

[0017] (3) Installing PV panels: Install the pre-assembled PV panels on the guide rails using locking nuts, pressure blocks and fastening bolts.

[0018] As a further description of the above technical solution, the studs are welded using a cold welding process.

[0019] As a further description of the above technical solution, the photovoltaic module includes a photovoltaic body and a connecting frame. The connecting frame is processed in the factory and the photovoltaic body is pasted on the connecting frame. All operations of the photovoltaic module are completed in the factory, which not only ensures the bonding strength of the structural adhesive and reduces the problems of hidden cracks and scratches on the photovoltaic body that are prone to occur during the transportation project, but also does not require on-site construction, reducing the intensity of on-site construction.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] (1) The detachable photovoltaic sound barrier device of the present invention only needs to weld studs on the mounting frame of the sound barrier device, and then the guide rail can be installed on the sound barrier device by nut connection, and then the photovoltaic module can be installed by tightening bolts, which is convenient for installation;

[0022] (2) Easy to disassemble. The photovoltaic modules can be disassembled from the sound barrier equipment without damage by simply removing the fastening bolts and taking away the pressure blocks. When the existing sound barrier equipment is damaged or exceeds its service life and needs to be replaced, the photovoltaic modules on it can be reused;

[0023] (3) During installation, there is no need to remove the original installation bolts of the sound barrier equipment, no need to use equipment such as hanging baskets and lifting vehicles, and no need to close road sections for construction. The construction difficulty is small, the installation process is simple and the construction period is short;

[0024] (4) The assembly of photovoltaic modules is carried out in the factory with a stable operating environment, which can ensure that the strength of the structural adhesive meets the requirements. BRIEF DESCRIPTION OF THE DRAWINGS
