Problems solved by technology
Since the fully enclosed tank cannot provide a pressure relief channel or volume compensation for the sharply increased pressure inside the tank, the seal of the tank is often damaged, resulting in severe aging and dampness of the insulating oil
It not only affects the effect of on-site insulating oil storage and treatment, increases the workload of oil workers, but also seriously affects the progress of on-site oil-filled equipment maintenance

Embodiment 1
[0033] A multifunctional alarm-type oil storage tank vacuum sealing device, including a sealing bottom cover, a miniature vacuum pump, an oil level monitoring and alarm control system, a vacuum degree monitor, and an air dryer, the sealing cover and the oil storage tank manhole cover The sizes and specifications are the same. There are vent holes and oil inlet holes on the sealing cover. There are air connection pipes on the vent holes and oil inlet pipes on the oil inlet holes. Connected with the vacuum pump, the oil inlet pipe extends into the inner cavity of the oil storage tank through the oil inlet hole on the sealed bottom cover. A telescopic oil pipe is arranged in the oil storage tank, and the telescopic oil pipe is connected with the oil inlet pipe. An oil inlet solenoid valve is arranged on the oil inlet pipe. The oil level monitoring and alarm control system includes an oil level monitoring and alarm control host, an oil level indicator and a float switch for automat...

The invention discloses a multifunctional warning type oil storage tank vacuum sealing device which comprises a sealing bottom cover, a micro vacuum pump, an oil level monitoring warning control system, a vacuum degree monitor and an air drier. The multifunctional warning type oil storage tank vacuum sealing device is simple and convenient to install and use, and various use performances of a simple horizontal type oil storage tank can be quickly improved only through simple installation on a manhole of the simple horizontal type oil storage tank. Therefore, the simple horizontal type oil storage tank has functions of micro vacuum negative pressure oil storage, vacuum linkage oil injection, air inlet automatic dehumidification drying, large opposite angle distance oil filtering, automatic real-time oil level monitoring warning and automatic shutdown after oil filling of an oil injection device. All-weather on-site oil treatment of insulating oil can be achieved, the on-site storage, oil filtering and oil level monitoring of the insulating oil are not subject to the influence of operation weather, environmental temperature and environmental humidity, the storage time of the insulating oil is effectively prolonged, and the on-site oil treatment working efficiency is improved.
Description
technical field [0001] The invention relates to a sealing device for an oil storage tank, in particular to a multifunctional alarm-type vacuum sealing device for an oil storage tank. Background technique [0002] In the power oil service work, it is often necessary to filter and store the insulating oil on site, but a large number of simple horizontal oil storage tanks used in the maintenance site generally have no oil deterioration prevention measures, poor sealing, poor oil filtering effect, Problems such as the amount of oil in the tank cannot be accurately monitored. [0003] Due to structural reasons, simple horizontal oil storage tanks usually use simple plugging to directly seal the insulating oil in the tank for storage. During the storage process, the oxygen and moisture in the air in the oil tank are absorbed by the insulating oil to promote the rapid aging of the insulating oil. Since there is no oil level gauge, when observing the internal oil lev...
