[0022] The present invention will be further described below with reference to the accompanying drawings. It is apparent that the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0024] The extrusion assembly 5 includes a first rolling cylinder 501 and a second rolling cylinder 502. The first rolling cylinder 501 and the second rolling cylinder 502 are both rotatably mounted on the fire fighting frame 1. One end of the first rolling cylinder 501 and the second rolling cylinder 502 extending to one side of the fire fighting frame 1 is connected to a rotating gear 503. The first rolling cylinder 501 and the second rolling cylinder 502 are hollow structures. The first rolling cylinder 501 and the second rolling cylinder 502 are provided with blowing holes 504 arranged in an array. The first rolling drum 501 and the second rolling drum 502 are provided with an air inlet pipe 505, and the other end of the air inlet pipe 505 is connected to the output end of the hot air blower 2. The hot air generated by the hot air blower 2 is transmitted to the air inlet pipe 505, the first rolling drum 501, and the inside of the second rolling drum 502, and the hot air is blown to the upper and lower surfaces of the water pipe through the blowing hole 504, thereby improving the drying efficiency of the water pipe and preventing water from coming into contact with the winding roller 3 along with the water pipe, thereby affecting the service life of the winding roller 3. Component 6 includes a driving gear 601 and a rotating shaft 602. The driving gear 601 is fixedly connected to the winding roller 3. The rotating shaft 602 is rotatably installed on the fire-fighting frame 1, and the rotating shaft 602 is located between the first rolling cylinder 501 and the second rolling cylinder 502. One end of the rotating shaft 602 is connected to a connecting gear 603, which meshes with the rotating gear 503. The other end of the rotating shaft 602 is connected to a driven gear 604. A chain 605 is meshed between the driven gear 604 and the driving gear 601. When the motor 4 rotates, the winding roller 3 rotates, the driving gear 601 rotates, and the driven gear 604 rotates through the chain 605. The connecting gear 603 rotates, so that the rotating gear 503 rotates in the opposite direction, and then the first rolling cylinder 501 and the second rolling cylinder 502 rotate in opposite directions, so that the water pipe can be squeezed to improve the extrusion quality. At the same time, the water pipe can move under the action of friction, thereby improving the water pipe winding efficiency.

[0025] The clamping assembly 7 includes a limiting rod 701, which is inserted into the limiting hole 8, and a circular plate 702 is provided at the upper end of the limiting rod 701, and a mounting seat 703 is connected to the lower end of the limiting rod 701. A clamping cylinder 704 is rotatably installed on the mounting seat 703, and a spring 705 is sleeved on the limiting rod 701. The two ends of the spring 705 are respectively fixedly connected to the circular plate 702 and the fire fighting frame 1. When the water pipe is wound, the clamping cylinder 704 rotates, and the limiting rod 701 moves, and the spring 705 expands and contracts, thereby compressing the water pipe, which can make the water pipe rolled up more tightly, thereby improving the winding quality.

[0026] When the utility model is in use, the motor 4 is started and the winding roller 3 rotates, which can reel the water pipe onto the winding roller 3, the driving gear 601 rotates, and the driven gear 604 rotates through the chain 605, and the connecting gear 603 rotates, so that the rotating gear 503 rotates in the opposite direction, and the first rolling cylinder 501 and the second rolling cylinder 502 rotate in the opposite direction, so that the water pipe can be squeezed, improving the squeezing quality. At the same time, under the action of friction, the water pipe moves, thereby improving the water pipe reeling efficiency, starting the hot air blower 2, and transmitting the generated hot air to the air inlet pipe 505, the first rolling cylinder 501, and the second rolling cylinder 502, and blowing the hot air to the upper and lower surfaces of the water pipe through the blowing hole 504, thereby improving the drying efficiency of the water pipe, thereby preventing water from contacting the winding roller 3 with the water pipe and affecting the service life of the winding roller 3, causing the limit rod 701 to move, the spring 705 to expand and contract, thereby pressing the water pipe, and reeling the water pipe more tightly, thereby improving the reeling quality.
