Description

Technical Field

[0001] The utility model relates to the technical field of fire protection engineering, in particular to a fire hydrant well insulation manhole cover. Background Art

[0002] In winter, due to the cold weather, when the fire hydrant well is not insulated, cold air enters the fire hydrant well through the fire hydrant well mouth, causing the fire water in the fire hydrant to freeze and block. The fire water freezing and blockage causes the valve to freeze and crack, and the valve cannot be opened, resulting in the fire hose cannot be effectively connected and the fire water cannot be supplied. Once a fire accident occurs, rescue cannot be carried out in time. In addition, the cold weather and the freezing of fire water cause the fire hydrant valve to freeze and crack, making it difficult for maintenance personnel to repair and replace the damaged valve, so it is necessary to use an insulation manhole cover to further protect the fire hydrant well.

[0003] For example, the utility model patent with application number CN201320288918.1 discloses a thermal insulation, waterproof and sealed manhole cover including an upper cover and a support, wherein the upper cover is buckled on the support; the bottom surface of the upper cover has an insulation groove facing the support, the insulation groove is filled with insulation material, the outer edge of the insulation groove has a circle of sealing groove, and the sealing ring is installed at the bottom of the sealing groove; the support is a frame, and the outer edge of the frame wall is also provided with a circle of sealing groove, and the bottom of the sealing groove is also installed with a sealing ring; after the upper cover is buckled on the support, the frame wall of the support is inserted into the sealing groove of the upper cover and abuts against the sealing ring in the groove, and the groove wall of the sealing groove of the upper cover is inserted into the sealing groove of the support and abuts against the sealing ring in the groove. The utility model can block the heat exchange between the well and the outside of the well, so that the heat in the well is preserved in the well and freezing will not occur in the well; in addition, the thermal insulation and waterproof sealed well cover includes an upper cover and a support and also has a waterproof function, so that water outside the well cannot enter the well, thereby protecting the instruments and other facilities in the well.

[0004] Although this thermal insulation and waterproof sealed manhole cover includes an upper cover and a support to prevent water outside the well from entering the well, thereby protecting instruments and other facilities in the well, the humid environment in the well can easily cause corrosion to the internal devices. The thermal insulation material of the device is filled in the thermal insulation layer, and there is a lack of protection for the thermal insulation material. Over time, the thermal insulation material is easily damaged, reducing the thermal insulation effect. At the same time, after the manhole cover is opened, the thermal insulation material may also be damaged due to collision; further improvement is needed. Utility Model Content
