Description

  The present invention addresses the dangers associated with the fuel outlet of fuel oil tanks installed outdoors in fuel oil (mainly white kerosene) tanks such as fuel oil stoves and heating / hot water boilers used in cold regions. Regarding protective cover.

  In fuel oil tanks installed outdoors, an oil feed port with a fuel filter and drain plug is provided on the bottom of the tank, and an oil feed pipe connected to the oil feed port is connected to an indoor fuel oil stove and a heating boiler through the ground. doing.

  In such a fuel oil tank installed outdoors, a dangerous incident has occurred in which the oil supply pipe is cut at night to cause the oil to flow out and the spilled oil is ignited.

  In view of this, there has been known one that addresses the danger associated with the oil feeding port by covering the oil feeding port on the lower surface of the tank and the oil feeding pipe connected thereto.

  For example, as shown in Design Registration No. 1207206, an upper and lower cylindrical cover that can expand and contract in the height direction is provided between an oil supply opening on the lower surface of the tank and the ground, and the oil supply is provided in the cylindrical cover. An opening and an oil supply pipe connected to the opening are accommodated, and a lockable opening / closing door is provided at a position corresponding to the oil supply opening at the top of the cover. The reason why it can be expanded and contracted is that the distance from the bottom surface of the tank to the ground may be different, so that openings are not formed above and below.
