7. A polyethylene pipe with fire protection structure according to any one of claims 1 to 6, comprising the following steps of use:
the method comprises the following steps: the protection of the joint of the polyethylene pipe is enhanced; after the two polyethylene pipes are spliced and connected, the connecting parts of the two polyethylene pipes cannot be directly exposed outside under the action of the external abutting frame (15), so that the connecting parts of the two polyethylene pipes are directly protected;
step two: expanding under heat; because the attaching extrusion frame (1503) is positioned at the outermost side, when the polyethylene pipe is burnt, the attaching extrusion frame (1503) is firstly burnt and heated, and when the attaching extrusion frame (1503) is heated and heated, the heated expansion bag (1502) is heated and expanded, and because the attaching extrusion frame (1503) limits the position of the heated expansion bag (1502), the heated expansion bag (1502) expands and extrudes towards the air storage bag (1501), so that the air pressure inside the air storage bag (1501) is increased;
step three: communicating water out; once the internal air pressure of the air storage bag (1501) is increased, the air pressure can extrude the upper and lower movable rods (1302) to enable the upper and lower movable rods (1302) to move downwards, then the blocking block (1304) in the pipe leaves the inside of the water supply communicating pipe (13) to realize the communication of the water supply communicating pipe (13), at the moment, water can enter the inside of the water supply communicating pipe (13), in addition, in the process of pressing the upper and lower movable rods (1302) downwards, the linkage guide rod (1305) moves downwards, and under the action of the inclined guide groove (103), the sliding block (104) is pressed downwards to enable the middle rotating rod (102) and the hinge baffle (101) to rotate, so that the hinge baffle (101) shields the inner cavity frame body (1) and the flow rate of water in the inner cavity frame body (1) is increased;
step four: spraying water for fire prevention; the water source entering the water feeding communicating pipe (13) enters the annular pipe (16) through the communicating groove (14), and then the water source can be sprayed out from the water spraying pipe (17) to achieve the purpose of fire prevention.
