Description

Technical Field

[0001] The utility model relates to the photovoltaic field, in particular to a floating body component and a waterproof and breathable plug. Background Art

[0002] At present, a buoy is used to make the photovoltaic bracket float on the water surface, so that the photovoltaic components installed on the photovoltaic bracket can effectively utilize the solar energy resources existing in the water surface space.

[0003] Existing floats are generally manufactured through a blow molding process, so at least one blow molding hole is formed on the float, and the blow molding hole is sealed by a plug to prevent water from entering the inner cavity of the float. The current plug completely seals the blow molding hole of the float, so that the inner cavity of the float is completely isolated from the outside world; however, due to changes in ambient temperature, completely isolating the inner cavity of the float from the outside world will cause a difference between the internal air pressure of the float and the external air pressure, causing the float to expand and contract due to heat and cold, which can easily lead to rupture of the float or a water leakage gap between the float and the plug.

[0004] In view of the above problems, it is necessary to study a floating body assembly and a waterproof and breathable plug, which can ensure the waterproofness of the floating body while making the air pressure inside and outside the floating body consistent to avoid the damage of thermal expansion and contraction to the floating body.

[0012] The plug cover is connected by welding or bonding to the top ends of the matching blocks of the matching part.

[0013] A reinforcement part is arranged in the air permeable channel, and the reinforcement part has a plurality of reinforcement ribs which are arranged separately and connected to the inner wall of the air permeable channel.

[0014] A baffle connected to the reinforcing portion is formed on one side of the air permeable channel away from the matching portion, and the baffle is provided with at least one air permeable hole communicating with the inner cavity of the air permeable channel.
