Detailed implementation manners

[0026] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings.

[0027] As Figure 1 and Figure 2 shown, an embodiment of the present application provides a waterproof fixture for installing a photovoltaic module, including a fixture assembly 100 installed on a purlin 102, and the fixture assembly 100 includes an I-shaped fixture 1 and two waterproof foam pads 2.

[0028] As Figure 1 shown, the I-shaped fixture 1 includes a first clamping plate 11, a second clamping plate 12 and a vertical plate 13 connecting the first clamping plate 11 and the second clamping plate 12. Two positioning grooves 14 for fixing the photovoltaic module 101 are formed between the first clamping plate 11, the second clamping plate 12 and the vertical plate 13.

[0029] As Figure 3 shown, two first grooves 111 for accommodating the waterproof foam pads 2 are provided at the bottom of the first clamping plate 11, and the waterproof foam pads 2 are attached in the first grooves 111.

[0030] Specifically, two symmetrical positioning grooves 14 are formed between the first clamping plate 11, the second clamping plate 12 and the vertical plate 13. The two first grooves 111 at the bottom of the first clamping plate 11 are respectively located on both sides of the vertical plate 13. The waterproof foam pads 2 are snapped into and attached in the first grooves 111, so that the waterproof foam pads 2 not only play a waterproof role, but also can avoid the waterproof foam pads 2 being exposed outside, thereby improving the service life of the waterproof foam pads 2. The first clamping plate 11 and the waterproof foam pads 2 are in contact with the top of the photovoltaic module 101, the first clamping plate 11 is in contact with the bottom of the photovoltaic module 101, and the vertical plate 13 is in contact with the side end of the photovoltaic module 101.

[0031] When installing the photovoltaic module 101, first place the I-shaped fixture 1 on the purlin 102, then respectively snap the edge parts of adjacent photovoltaic modules 101 into the two positioning grooves 14, and then fixedly connect the purlin 102, the I-shaped fixture 1 and the photovoltaic module 101 through a plurality of bolt assemblies 122. A backing plate 3 is padded between the photovoltaic module 101 and the purlin 102, and the backing plate 3 is fixed on the purlin 102 so that the photovoltaic modules 101 are in the same horizontal position, achieving a good waterproof effect as a whole.

[0032] In the above structure, by setting the I-shaped fixture 1 and the waterproof foam gasket 2, adjacent photovoltaic modules 101 are fixed, thereby playing a waterproof role in the gap between adjacent photovoltaic modules 101. This waterproof fixture for photovoltaic module installation has a simple structure, good waterproof effect, and a long service life.

[0033] As Figure 1 shown, in one embodiment, a plurality of mounting holes 121 are symmetrically arranged on the second clamping plate 12 of the waterproof fixture for photovoltaic module installation, and the mounting holes 121 of the second clamping plate 12 are connected to the photovoltaic module 101 and the purlin 102 through bolt assemblies 122.

[0034] Specifically, two mounting holes 121 are symmetrically arranged at the bottom of the second clamping plate 12 respectively, and the bolt assembly 122 passes through the mounting holes 121 of the purlin 102 and the second clamping plate 12 and is threadedly fixedly connected to the photovoltaic module 101. This setting facilitates the fixation of the purlin 102, the I-shaped fixture 1 and the photovoltaic module 101.

[0035] As Figure 4 shown, in one embodiment, a backing plate 3 is arranged between the photovoltaic module 101 and the purlin 102 of the waterproof fixture for photovoltaic module installation, and the thickness of the backing plate 3 is the same as the thickness of the second clamping plate 12.

[0036] Specifically, the thickness of the backing plate 3 is the same as the thickness of the second clamping plate 12 of the I-shaped fixture 1, and the backing plate 3 is fixed between the edge of the purlin 102 and the photovoltaic module 101 through the second bolt assembly 122. The setting of this backing plate 3 facilitates fixing the bottom of the photovoltaic module 101 on the same horizontal plane.

[0037] As Figure 1 shown, in one embodiment, the I-shaped fixture 1 of the waterproof fixture for photovoltaic module installation is made of aluminum alloy. This aluminum alloy fixture not only has a light weight and is convenient to operate, but also perfectly combines with the aluminum frame of the photovoltaic module 101, with a neat and beautiful appearance.

[0038] As Figure 3As shown, in one embodiment, the waterproof foam pad 2 of the waterproof clamp for photovoltaic module installation is made of ethylene propylene diene monomer (EPDM). This EPDM material has good elasticity and is easily snapped into and fitted into the first groove 111 of the I-shaped clamp 1. Moreover, this material has strong weather resistance and a service life of up to 30 years, which is basically the same as that of the photovoltaic module 101.

[0039] As Figure 1 and Figure 3 shown, in one embodiment, the two side ends of the first clamping plate 11 of the waterproof clamp for photovoltaic module installation are respectively provided with inclined ends 112 that incline outward. When it rains, rainwater flows out along the two inclined ends 112 of the first clamping plate 11. The setting of these two inclined ends 112 effectively enhances the waterproof effect of the I-shaped clamp 1.

[0040] As Figure 1 shown, in one embodiment, the length of the second clamping plate 12 of the waterproof clamp for photovoltaic module installation is longer than that of the first clamping plate 11. This setting not only facilitates the fixation of the photovoltaic module 101, but also the first clamping plate 11 does not block the photovoltaic module 101.

[0041] The above embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
