[0002] The oil tank manhole is a container that provides protection for the joints, valves, oil pumps and underground pipeline joints of the underground oil tanks of gas stations. The Chinese utility model patent, authorization announcement number "CN219669028U", discloses a manhole for oil tanks with an early warning function. Its technical solution includes: an oil tank body, a manhole body and an inlet and outlet oil pipe are arranged on the top of the oil tank body, and the inlet and outlet oil pipes are located on the inner side of the manhole body, and a liquid level detection sensor is arranged on one side of the inlet and outlet oil pipes. The top of the manhole body is equipped with an end cover, and a box is installed at the center of the upper surface of the end cover. The bottom of the box is equipped with a PLC controller, an inverter and a battery from left to right. The utility model can not only detect whether the inlet and outlet oil pipes leak flammable gas in real time, but also detect the liquid inside the manhole body.
