Intelligent switching type photovoltaic support

The invention relates to the field of photovoltaic panel supports, in particular to an intelligent switching type photovoltaic support. The technical problems that in the sinking process of an existing device, impurities on the water surface easily flow to the surface of the device to affect heat dissipation of a photovoltaic panel, and dust accumulation on the surface of the photovoltaic panel can also affect power generation and heat dissipation of the photovoltaic panel; under the condition that the temperature is low, an existing device is prone to being hindered whether falling or floating, and normal operation is difficult. According to the technical scheme, the intelligent switching type photovoltaic support comprises an air bag, a protection box and the like; and a protective box is arranged above the airbag. Through cooperation of the first floating plate and the second floating plate, the waterproof cloth is always higher than the water surface, water is prevented from entering the protection box, a
