Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and in particular to a novel trapezoidal tile railless BIPV system. Background Art

[0002] The current common roof BIPV practice is to match photovoltaic modules with customized roof tiles, using a rail-free installation method, with roof tiles as the support and drainage system. This practice is relatively common, but there are problems with heat dissipation. The modules are attached to the wave crest of the tiles, so that only one-way ventilation can be achieved underneath the modules, resulting in slow heat dissipation, which in turn affects the power generation efficiency and service life of the modules.

[0003] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0004] In view of the problems in the related technology, the utility model proposes a novel trapezoidal tile railless BIPV system to overcome the above-mentioned technical problems existing in the existing related technology.

[0005] To this end, the specific technical solutions adopted by the utility model are as follows:

[0006] A novel trapezoidal tile railless BIPV system comprises a trapezoidal tile, a photovoltaic module and a rail-free photovoltaic fixing, wherein the rail-free photovoltaic fixing comprises an upper clamping plate, a lower clamping plate and a trapezoidal base, wherein the top of the lower clamping plate is fixedly connected with a connecting column, the bottom of the lower clamping plate is fixedly connected with an upper connecting tube, the top of the trapezoidal base is fixedly connected with a lower connecting tube, the upper connecting tube and the lower connecting tube are fixed together by means of a threaded connection, a waterproof gasket is provided at the bottom of the trapezoidal base, and a self-tapping screw is provided in the lower connecting tube.

[0007] As a further solution of the utility model, the trapezoidal tiles, photovoltaic modules and rail-free photovoltaic fixings are all made of aluminum-magnesium-manganese materials.

[0008] As a further solution of the utility model, the height of the trapezoidal tile is 38 mm.

[0009] As a further solution of the utility model, the rail-free photovoltaic fixing device is provided with a hidden self-tapping screw, the screw head of the self-tapping screw is enclosed in the lower connecting tube, the waterproof gasket under the trapezoidal base is completely in fit with the front of the trapezoidal tile crest, the self-tapping screw is fixed at the front position of the trapezoidal tile crest, and downward-folded water-stop edges are provided on both sides of the trapezoidal base. The rail-free photovoltaic fixing device can be coated with weather-resistant glue under the waterproof gasket and at the upper end of the trapezoidal base.

[0010] As a further solution of the utility model, the photovoltaic module can be installed on the trapezoidal tile in a combination of horizontal and vertical installation methods.

[0011] As a further solution of the utility model, the installation steps are as follows:

[0012] Step 1: Set the purlin spacing in advance so that the reasonable fixing point of the photovoltaic module is in a straight line with the center of the purlin, and install the purlin by using the formwork method so that each purlin maintains the set spacing;

[0013] Step 2: After laying the trapezoidal tiles on the purlins, place the trapezoidal base on the crest of the trapezoidal tiles at the preset position by using a formwork method, and then use self-tapping screws to lock the trapezoidal base, waterproof gasket and trapezoidal tiles on the purlins at the same time. The self-tapping screws pass through the trapezoidal outer and purlins at the same time, and one nail serves two purposes, which can improve the wind resistance of this system;

[0014] Step 3: Screw the lower clamping plate onto the trapezoidal base, and adjust the screws to ensure that each lower clamping plate maintains a uniform height and direction;

[0015] Step 4: Place the photovoltaic module on top of the four lower clamping plates according to the preset position;

[0016] Step 5. Align the bolt holes of the upper clamping plate to the top of the connecting column of the lower clamping plate, and press both sides of the upper clamping plate onto the frame of the photovoltaic module. Then, use bolts to lock the upper clamping plate and the connecting column together to clamp and fix the photovoltaic module.

[0017] The beneficial effects of the utility model are:

[0018] 1. The height of the upper connecting tube and the lower connecting tube is increased between the photovoltaic modules and the trapezoidal tile crests of this system, so that the distance between the photovoltaic modules and the trapezoidal tiles is just right, which not only has the aesthetics of the roof BIPV, but also does not cling to the trapezoidal tile crests. The photovoltaic modules can be ventilated in all directions, and the system has good heat dissipation performance, which does not affect the power generation efficiency and service life of the photovoltaic modules;

[0019] 2. This system saves the cost of photovoltaic rails and installation. At the same time, the roof tiles adopt trapezoidal tiles, which have high material utilization and low installation cost, reducing the photovoltaic investment cost. In addition, this system is faster to install and convenient for later maintenance and disassembly, so it has the advantage of high cost performance. BRIEF DESCRIPTION OF THE DRAWINGS

This arrangement can make full use of each space and increase the utilization rate of the roof.

[0035] In one embodiment, please refer to the attached specification Figure 1-6 As a further solution of the utility model, the installation steps are as follows:

[0036] Step 1: Set the purlin spacing in advance so that the reasonable fixing point of the photovoltaic module 2 is in a straight line with the center of the purlin, and install the purlin by using a mold to ensure that each purlin maintains the set spacing;

[0037] Step 2: After laying the trapezoidal tile 1 on the purlin, place the trapezoidal base 34 on the crest of the trapezoidal tile 1 at the preset position by using a formwork method, and then use self-tapping screws 38 to lock the trapezoidal base 34, waterproof gasket 37 and trapezoidal tile 1 on the purlin at the same time. The self-tapping screws 38 pass through the trapezoidal outer 1 and the purlin at the same time, and one nail serves two purposes, which can improve the wind resistance of the system;

[0038] Step 3: Screw the lower clamping plate 32 onto the trapezoidal base 34, and adjust the screws to ensure that each lower clamping plate 32 maintains a uniform height and direction;
