3results about How to "Prevent snow" patented technology

A winter defense facility which is suitable for actively preventing snow weather from harming roads in advance in winter in the north comprises stand columns, a cross beam, an arch crown, a wind shield, reinforcing ribs, a metal net, an auxiliary arch top and the like. A long shed for shielding a road and a round shed for leisure and entertainment of people are formed by vertical columns, a cross beam, a vault, reinforcing ribs, a metal net, a wind shield and an auxiliary vault (support). Due to the establishment of the long shed and the round shed, the trouble of removing accumulated snow on the road and accumulated snow on the site can be avoided, and the interference of wind and snow on production and life can be solved. During installation, the main columns, the cross beams and the vault are connected and fixed into a frame, and the metal net with the reinforcing ribs and the auxiliary vault (support) are fixed on the frame. When snow falls, the snow falls on the metal net, blocks the holes of the metal net and is stacked to form a snow layer, the reinforcing ribs and the metal net form a firm skeleton of the snow, and a firm protection body capable of shielding both wind and snow is formed.

This utility model discloses a corrosion-resistant and cold-proof device for photovoltaic supports in high-altitude and cold-weather regions. It includes a stable base, a support frame assembly connected to the top of the stable base, an end frame assembly at the top of the support frame assembly, a side frame assembly inside the end frame assembly, and a reinforcing frame assembly at the bottom of the side frame assembly. The reinforcing frame assembly is composed of a main support body, an anti-corrosion layer, a hydrophobic layer, and an anti-UV layer. The anti-UV layer is made of fluorocarbon topcoat, the anti-corrosion layer is made of epoxy micaceous iron oxide intermediate paint, and a hydrophobic layer and an anti-UV layer are respectively provided on the outer wall of the anti-corrosion layer. The main support body is made of hot-dip galvanized steel. The end frame assembly includes the main support body, which has an internal chamber containing an electric heating tape. The outer wall of the main support body is provided with the anti-corrosion layer, the hydrophobic layer, and the anti-UV layer. This device prevents snow accumulation and corrosion, thereby extending its service life and reducing maintenance costs.

The application discloses a photovoltaic module temperature control system, which is configured to be connected to a photovoltaic panel, the photovoltaic panel has a light-receiving surface and a back surface, and the photovoltaic module temperature control system comprises a frame body and a temperature control assembly. The frame body is provided with a through groove for nesting the back surface of the photovoltaic panel. The temperature control assembly comprises a plurality of temperature control pieces which are arranged at intervals and are distributed in an array along the surface of the back surface of the photovoltaic panel. The temperature control piece comprises a phase change energy storage part which is configured to be connected to the photovoltaic panel and abuts against the back surface of the photovoltaic panel, so that the temperature of the photovoltaic panel can be maintained within a preset temperature range. The application can effectively solve the problem that a person needs to clean the snow and ice on the photovoltaic panel after the photovoltaic panel is covered with snow or ice under cold conditions.
