Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a photovoltaic component pressing block capable of conducting water and discharging mud. Background Art

[0002] The current photovoltaic module structure on the market is as follows Figure 1 As shown, it is composed of a photovoltaic module 4, a packaging glue 3, and an aluminum alloy frame 6. The aluminum alloy frame 6 wraps the photovoltaic module 4 and is packaged with the packaging glue 3. A circle of aluminum alloy frame will be formed at the edge which is higher than the solar panel. The rigidity of the photovoltaic module thus formed can meet the standard requirements.

[0003] For PV modules with an installation angle of ≤5°, when it rains, the fluidity of rainwater on the surface of the PV modules is low, and dust is easily accumulated on the inner side of the junction between the frame and the PV modules, which is difficult to drain away. After the rainwater dries, a certain area of ​​dust accumulation will remain, which will affect the power generation efficiency of the PV modules and cause uneven heat dissipation of the PV modules, further affecting the service life of the PV modules.

[0004] The existing photovoltaic module blocks have a simple form and function, and the structure is as follows Figure 1 , Figure 2 , Figure 3 As shown, the photovoltaic module is fixed by the anti-skid grooves 1.6 under the pressure plates 1.3 on both sides of the pressing block and the bolt mounting holes 1.5 through the bolts of the pressing block, which can only fix the frame of the photovoltaic module. It cannot play the role of draining mud and guiding water for the accumulated water and dust at the frame of the photovoltaic module installed at a small angle. In addition, when the installation slope of the photovoltaic module is consistent with the installation direction of the pressing block, the pressing block is installed on the side of the accumulated water and dust. Since the pressing block has a certain thickness when clamped at the frame of the photovoltaic module, the accumulated water and dust here are more difficult to discharge, and the traces of dust accumulation are more serious.

[0005] The photovoltaic module pressing block disclosed in Chinese patent CN202320365432.7 includes a mounting portion and a pressing portion for cooperating with the photovoltaic module frame, one end of the pressing portion is fixed to the mounting portion, and the pressing portion is provided with a matching surface for forming a surface-to-surface match with the pressed portion of the photovoltaic module frame. The above patent structure is to provide a matching surface on the pressing portion for forming a surface-to-surface match with the pressed portion of the photovoltaic module frame, which can reduce the pressure on the pressing portion, not only avoiding the wear of the pressing block, but also avoiding the risk of the photovoltaic module frame being torn; but it still does not have the function of guiding water and mud. Utility Model Content

[0006] The purpose of the utility model is to overcome the problems existing in the above-mentioned existing technologies and to provide a photovoltaic module pressing block that can conduct water and drain mud. The utility model utilizes its own structure to be divided into a pressing block stress area and a pressing block water conducting area, thereby achieving the dual functions of fixing the photovoltaic module and conducting water and draining mud, thereby improving the installation efficiency of the accessories of the photovoltaic module; the construction and installation are more convenient and more efficient.

[0007] The technical solution adopted by the utility model is:

[0008] A photovoltaic module pressing block capable of conducting water and draining mud is characterized in that: the overall structure is in the shape of an inverted Chinese character "X", and is composed of a pressing plate and a water diversion plate, both of which are in the shape of an inverted Chinese character "X", a bolt mounting hole is provided at the bottom of the pressing plate, and the water diversion plate is distributed on the side of the pressing plate; the pressing plate is used to fix and press the frame of the photovoltaic module; the water diversion plate is used to divert water from the frame to prevent rainwater and mud from accumulating at the frame position.

[0009] The two ends of the water guide plate extend outwardly to form an eagle's beak shape with pointed ends for piercing the surface of the accumulated water at the frame to destroy the tension of the accumulated water surface, so that when the accumulated water and mortar accumulate at the frame, they can be guided to flow over the frame in time.

[0010] The height of the water diversion plate is lower than that of the pressing plate, and the width of the water diversion plate is smaller than that of the pressing plate.

[0011] The bottom of the "X"-shaped bend of the pressing plate is provided with an anti-skid groove for pressing the component frame to prevent relative sliding.

[0012] A plurality of air holes are arranged on the water guide plate for ventilation during diversion, so as to reduce the negative pressure in the diversion channel and make the water diversion and mud discharge smoother.

[0013] The utility model combines the dirt removal, mud discharge and water diversion functions of the pressing block with the component frame. The installed pressing block has the function of water diversion and mud discharge. After the component pressing block is installed, there is no need to install a water diversion and mud discharge clamp separately. The pressing block function and the water diversion function are concentrated on one accessory, which greatly improves the installation efficiency and installation effect of the component and saves installation steps and installation time.
