Full-automatic energy-saving anti-freezing device

Abstract

The invention discloses a full-automatic energy-saving anti-freezing device which is composed of a heat preservation box body, a control electric appliance and a conversion mechanism; the heat preservation box body is composed of an inner storage box, an outer heat preservation box body and a heat preservation material; the control electric appliance is composed of a bidirectional motor, a suctionswitch assembly, a power combination switch, a liquid level sensor assembly, a temperature sensor W, a thermometer T, a liquid level meter H, a positive rotating coil M1, a reverse rotating coil M2,a variable resistance coil B, a fuse wire R and a suction-pull coil S; the conversion mechanism is composed of a bidirectional pump wheel, a pulling pile-shaped valve, an air inlet valve assembly andan exhaust valve assembly. The device has the advantages of being light and convenient to operate, not only solving the problem of difficulty in winter construction, but also being safe and reliable,being free of pollution, high in working efficiency, low in labor intensity, light and simple in structure, low in manufacturing cost, and easy to install, and the heat in the liquid can be effectively stored and reused, the conventional starting time is shortened, the preheating fuel is saved, and the service life of the machine is prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical safety devices, in particular to a fully automatic energy-saving antifreeze device. Background technique [0002] Nowadays, construction machinery often needs winter maintenance. The main maintenance items in the past are; 1. Either take insulation measures. Second, either replace the oil or add antifreeze. Three, water treatment. [0003] There are many shortcomings in this conventional way unsatisfactorily; 1, because the large structure shape of body is not uniform and is difficult to accomplish integral heat preservation, even if accomplish, engineering quantity is also big, and heat preservation result is not good. 2. In severe cold areas in winter, people are often sent to watch the night, and the internal combustion engine is used to provide heat to maintain the temperature of the machine. 3. It takes a lot of manpower and material resources to change water and oil, including lubricat...
