Description

Technical Field

[0001] This application relates to the field of photovoltaic panels, and more specifically, to an M-groove for a photovoltaic roof system. Background Technology

[0002] Photovoltaic roof systems generate a lot of heat during operation. If the heat cannot be dissipated in time, it will affect the power generation efficiency of the photovoltaic modules and even shorten the life of the modules.

[0003] A common solution involves placing water pipes under the photovoltaic panels. The lower temperature of the water pipes causes water vapor to condense and form a thin water film on the pipes. This thin water film evaporates and absorbs heat to dissipate heat around the photovoltaic panels. However, this can lead to poor drainage during rainy weather. Utility Model Content

This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] Furthermore, the M-shaped water tank is located between two photovoltaic panels.

[0007] Furthermore, the M-shaped water tank is connected to the photovoltaic panel via a pressure block and a crossbeam;

[0008] The crossarm is located above the M water tank, and the pressure block is fixed to the crossarm and presses down on the photovoltaic panel.

[0009] Furthermore, the M-shaped water tank portion comes into contact with the photovoltaic panel.

[0010] Furthermore, the pressure block is located between the two photovoltaic panels, and the pressure block simultaneously presses down on the two photovoltaic panels.

[0011] Furthermore, the first connecting part of the M-shaped water tank simultaneously abuts against two photovoltaic panels.

[0012] The beneficial effects of this application are as follows:

[0013] The third connecting part and the two second connecting parts are used to form a water guiding channel, which is set in the open air, so as to facilitate the collection and discharge of rainwater, thus ensuring both heat dissipation and waterproofing. Attached Figure Description

[0027] An M-shaped water tank for a photovoltaic roof system comprises two first connecting parts 1, two second connecting parts 2 located at both ends of the first connecting parts 1 and extending downwards respectively, a third connecting part 3 located between the two first connecting parts 1 and connecting the two second connecting parts 2, and a fourth connecting part 4 connected to the second connecting parts 2 and extending outwards; the third connecting part 3 and the two second connecting parts 2 enclose each other to form a water guiding channel; the fourth connecting part 4 is used to connect with the purlins of the photovoltaic roof system.

[0028] By adopting the above scheme, the third connecting part 3 and the two second connecting parts 2 are used to form a water guiding channel, so that the water guiding channel is set in the open, which facilitates the collection and discharge of rainwater, thus ensuring both heat dissipation and waterproofing.

[0029] Specifically, the M-shaped water tank is located between two photovoltaic panels 7. After rainwater falls on the photovoltaic panels 7, it can drain into the M-shaped water tank along the tilt of the photovoltaic panels 7.

[0030] Specifically, the M-shaped water tank is connected to the photovoltaic panel 7 via a pressure block 5 and a crossbeam 6; the crossbeam 6 is located above the M-shaped water tank, the pressure block 5 is fixed to the crossbeam 6, and the pressure block 5 presses down on the photovoltaic panel 7. The M-shaped water tank is in contact with the photovoltaic panel 7.

[0031] Specifically, the pressure block 5 is located between the two photovoltaic panels 7, and the pressure block 5 presses down on both photovoltaic panels 7 at the same time.

[0032] Specifically, the first connecting part 1 of the M water tank simultaneously abuts against two photovoltaic panels 7.

[0033] In other embodiments, through holes are provided on the second connecting part 2 and the fourth connecting part 4, and connecting water pipes are inserted through the through holes. The connecting water pipes are used to connect the water guiding channels of multiple M water tanks. The connecting water pipes are located below the photovoltaic panel 7, and multiple connecting water pipes and through holes are provided, so that the connecting water pipes are staggered below the photovoltaic panel 7. The connecting water pipes are used to increase the drainage speed of the M water tanks during rainy weather. A control valve is provided on the connecting water pipe. In non-rainy weather, the control valve is closed or reduced, so that water exists in the connecting water pipe, which can reduce the air temperature below the photovoltaic panel 7, thereby improving the heat dissipation effect of the photovoltaic panel 7.

[0034] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
