Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower, and more specifically, to an anti-freezing device for environmental protection type hydropower equipment. Background Technique

[0002] Some problems exist in the use of previous anti-freezing devices for water conservancy and hydropower equipment. For example, they do not have the advantage of light energy utilization, cannot convert light energy into electrical energy, easily cause waste of commercial power, and cannot conform to the trend of energy conservation and environmental protection in the era, thus unable to meet the current market demand. Due to the above problems, the practicability and usability of the anti-freezing device for water conservancy and hydropower equipment are reduced.

[0003] Patent authorization number CN218442787U discloses an anti-freezing device for environmental protection type water conservancy and hydropower equipment, including a water conservancy and hydropower generating unit. The right side of the water conservancy and hydropower generating unit is fixedly connected with a box body. The water conservancy and hydropower generating unit is communicated with the box body. The left side of the box body is penetrated with a heat conduction plate, and the left side of the heat conduction plate is in contact with the left side of the water conservancy and hydropower generating unit. The right side of the inner cavity of the box body is fixedly connected with a heating plate. Through the cooperation of the water conservancy and hydropower generating unit, the box body, the heat conduction plate, the heating plate, the heating pipe, the rotating rod, the turntable, the stirring blade, the servo motor, the first vertical rod, the second vertical rod, the cross plate, the support rod, the power generation plate, the power supply and the transformer, it realizes the advantage of being able to utilize light energy, and solves some problems existing in the use of previous anti-freezing devices for water conservancy and hydropower equipment, such as not having the advantage of light energy utilization, not being able to convert light energy into electrical energy, easily causing waste of commercial power, and not conforming to the trend of energy conservation and environmental protection in the era.

[0004] However, in patent authorization number CN218442787U, solar energy is converted into electrical energy to keep the electromechanical equipment warm and prevent freezing. Due to the limited amount of electrical energy converted from solar energy, the electrical energy cannot be reasonably utilized, resulting in waste of some electrical energy and inability to better achieve energy conservation. There is still room for improvement. Therefore, we propose an anti-freezing device for environmental protection type hydropower equipment to solve the above existing problems.
