Because the drainage layer 14 is in the same plane as the bottom valve of the fire fighting equipment, when the bottom valve is opened to drain the fire fighting equipment barrel, accumulated water inside the barrel can flow into the gap in the drainage layer 14 from the bottom valve. And because the drainage layer 14 is a stone layer instead of fine earth of stratum, the bottom valve 200 can be freely opened and closed, accumulated water can flow out from gaps among stones and cannot be blocked, so that the accumulated water in the cylinder body is completely drained, and the hidden danger of freezing and blocking is avoided. Meanwhile, because the bottom valve is generally made of cast iron, the drain layer 14 prevents the bottom valve 200 from being in a humid environment for a long time, which may cause a corrosion problem and affect the service life of the bottom valve.

In this way, the provision of the outer shell 11 enhances the resistance of the fire fighting equipment to external influences.

Secondly, lay one deck stone layer on footing 15 for the junction of fire-fighting equipment and fire-fighting water pipeline is the center on this stone layer, and the barrel of fire-fighting equipment wears out from the stone layer. When clearing up ponding in the barrel of fire-fighting equipment, can open bottom valve 200 and discharge ponding, because the setting on stone layer, ponding can discharge smoothly, and can not flow into in the fine soil and block up bottom valve 200 for bottom valve 200 can free activity, and can not lead to the corrosion problem. Especially, when the temperature is lower, because the barrel ponding of fire-fighting equipment is discharged very cleanly, consequently, the hidden danger of freezing stifled can not appear in the barrel of fire-fighting equipment.

Thirdly, in the middle of the shell 11, the through hole of the second supporting body 132 in the second insulating layer 13 passes through the cylinder of the fire fighting equipment, the second supporting body 132 is detachably and fixedly connected with the shell 11, the through hole of the second insulating body 131 in the second insulating layer 13 passes through the cylinder of the fire fighting equipment, and the second insulating body 131 is placed on the second supporting body 132.

Finally, at the top of the housing 11, the through hole of the first supporting body 122 in the first heat insulating layer 12 passes through the cylinder of the fire fighting equipment, the first supporting body 122 is detachably and fixedly connected with the housing 11, the through hole of the first heat insulating body 121 in the first heat insulating layer 12 passes through the cylinder of the fire fighting equipment, and the heat insulating body 121 is placed on the first supporting body 122.

When the field personnel inspect the barrel of the fire-fighting equipment, the support body is arranged to support and fix the fire-fighting equipment, so that the fire-fighting equipment is protected from shaking or settling. And field personnel can directly take out the heat insulator and the supporting body, so that the operation of the field personnel and the inspection of fire fighting equipment are facilitated, and the maintenance cost is saved. Meanwhile, the arrangement of the heat insulation body also effectively improves the heat insulation effect of the fire-fighting equipment and avoids the hidden danger of freezing and blocking.

The fire-fighting equipment's that this embodiment provided drainage system, the entering of the fine soil in stratum has been completely cut off through setting up of shell, and first heat preservation and second heat preservation are connected with the shell respectively, and all include supporter and heat-insulating body in first heat preservation and the second heat preservation, and the barrel of fire-fighting equipment is all passed to the through-hole of supporter and heat-insulating body, can prevent to rock or subside about fire-fighting equipment, still plays the heat preservation effect to fire-fighting equipment. And the drainage blanket can be the stone layer, and the gap between the stone makes the ponding discharge in the barrel of fire-fighting equipment very clean for the bottom valve of fire-fighting equipment can free activity. The drainage system of the fire fighting equipment can play a role in heat preservation of the fire fighting equipment, effectively avoids the problems of blockage caused by the fact that fine earth in the stratum enters the bottom valve, corrosion and freezing and blocking hidden dangers caused by low temperature, and saves the maintenance cost of the fire fighting equipment.
