Background
In order to plant vegetables in winter in cold areas, the use of light-transmitting plastic film greenhouses in cold areas has been common. Greenhouse built in cold area is threatened by winter snowfall. Because the slope of the top of the greenhouse is slower, snow cannot naturally slide down to form accumulation, and under the condition of large snow fall, the snow weight can fracture the greenhouse film to enable crops in the greenhouse to be frozen, and even the greenhouse frame is crushed to cause the collapse of the greenhouse, so that double losses of the greenhouse and the crops in the greenhouse are caused. In the past, snow in the greenhouse is manually cleared, and the snow is also a common cleaning tool, so that the labor intensity is high. Especially, people who fall snow and remove snow at night are more hard. When snow is big and the snow is urgent, the greenhouse cannot be damaged due to insufficient manpower. In addition, because the roof is high, has slope, surface slip, there is the accident emergence of falling injury when artifical snow removing in. In areas with larger snowfall in winter, snowfall increases the production cost and risk of crops in the greenhouse, and the grower of the crops in the greenhouse is free from worry about snow damage.
