Claims

[Scope of Claim for Utility Model Registration] (1) A closing structure in which a lid 4 is attached to the upper end of the opening of a lid receiving ring 3 fixed so as to communicate with the suction pipe inlet 2 of a waterproof water tank, The lid receiving ring 3 is attached to the peripheral edge 5 of the suction tube input port 2.
A ring-shaped fixing part 6 is fixed to a ring-shaped lid receiving part 7 and a rising wall 9 provided around its outer periphery.
A lid fitting part 10 is formed, and the lid 4 has a peripheral edge part 14 that forms the lid fitting part 10.
Grease or the like is applied between the upper surface 11 of the lid receiver and the lower surface 15 of the lid periphery and between the inner peripheral surface 12 of the rising wall and the outer peripheral surface 17 of the lid periphery. A lid structure for a fire prevention water tank that eliminates the difficulty of opening the lid due to freezing, characterized by the inclusion of an oil that does not easily freeze. (2) A lid structure in which a lid is attached to the upper end of the opening of a lid receiving ring 3 fixed so as to communicate with the suction pipe inlet 2 of the fire prevention water tank, and the lid receiving ring 3 is connected to the suction pipe inlet 2. 2 peripheral part 5
A ring-shaped fixing part 6 is fixed to a ring-shaped lid receiving part 7 and a rising wall 9 provided around its outer periphery.
The lid fitting part 10 has an annular ring having an L-shaped cross section that can come into contact with the top surface 11 of the lid receiving part and the inner circumferential surface 12 of the rising wall 9. A gasket 13 is attached, and the annular gasket 13 is impregnated with a hard-to-freeze oil such as grease, or the entire inner surface 19 of the gasket 13 is coated with oil. The gasket is placed on the upper surface 16 of the gasket 13 at the lower circumferential surface 15, and the outer circumferential surface 17 of the circumferential edge is in approximately contact with the inner circumferential surface 19 of the gasket, as if it were covered. A fire prevention water tank lid structure that eliminates the difficulty of opening the lid.
