[0002] The fire hose is one of the important firefighting equipment used for firefighting. It is usually made of rubber or polymer, and is flexible and wear-resistant. The fire hose is connected to a water source (such as a fire hydrant or a fire pump) and delivers water to the fire scene through water pressure to extinguish or control the fire. In the process of using the fire hose, a winding device is required, which can realize the winding of the fire hose.

DETAILED DESCRIPTION

[0030] Reference Figure 1As shown, the utility model provides a technical solution: a fire hose winding device, including a support frame 1, the support frame 1 is internally rotatably connected to a rotating shaft 3, the side wall of the rotating shaft 3 is fixedly connected to a winding roller 2, the surface of the support frame 1 is provided with a control structure 4, and the surface of the support frame 1 is provided with a compression structure 5.

[0031] The specific settings and functions of the control structure 4 and the compression structure 5 are described in detail below.

[0032] Reference Figure 1-Figure 2 and Figure 4-Figure 5 As shown, in this embodiment: the control structure 4 includes two mounting rods 403 fixedly mounted on the surface of the support frame 1, and the mounting ring 402 is fixedly mounted on one end of the two mounting rods 403 close to each other, and the motor 401 is fixedly mounted on the inner side of the mounting ring 402, and the output end of the motor 401 is fixedly mounted with an output shaft 404, and a slot 410 is provided on the surface of the output shaft 404, and an insert block 405 is slidably connected inside the rotating shaft 3, and the size of the insert block 405 is adapted to the size of the slot 410. The insert block 405 is inserted into the inner side of the slot 410 on the output shaft 404, so that the locking docking work between the rotating shaft 3 and the output shaft 404 can be realized. The side wall of the insert block 405 is fixedly connected with a pull block 406, and the pull block 406 is located on the inner side of the rotating shaft 3. When the pull block 406 is pulled, the pull block 406 will drive the insert block 405 to be pulled out from the inner side of the slot 410. A spring 409 is fixedly connected between the pull block 406 and the inner side of the rotating shaft 3. The pull block 406 is driven by the elastic force of the spring 409 to drive the insert block 405 to be inserted into the inner side of the slot 410 on the output shaft 404. The side wall of the rotating shaft 3 is fixedly connected with a connecting plate 408, and the surface of the connecting plate 408 is rotatably connected with a stopper 407. The stopper 407 on the rotating connecting plate 408 is blocked on the surface of the pull block 406 by rotating the stopper 407, so as to realize temporary support work for the pull block 406 and the insert block 405 after the movement.

[0033] Reference Figure 1 and Figure 3 As shown, specifically, the compression structure 5 includes a positioning plate 52 fixedly connected to the side wall of the support frame 1, and two sliders 54 are slidably connected to the inner side of the positioning plate 52, and a circular rod 53 is rotatably connected inside the slider 54. By setting the compression structure 5, the extrusion of the water inside the fire hose during the winding process of the fire hose is facilitated, and the winding efficiency of the fire hose is further improved. The side wall of the circular rod 53 is rotatably connected to the roller 51. The rotation of the roller 51 on the surface of the circular rod 53 reduces the phenomenon of large friction generated during the movement of the fire hose, and improves the resistance to the pumping of the fire hose. The internal thread of the positioning plate 52 is connected to a drive rod 55, and the drive rod 55 is rotatably connected to the inside of the slider 54. Rotating the drive rod 55 can realize the driving work of the slider 54 inside the positioning plate 52, thereby facilitating the adjustment of the compression force of the fire hose.

[0034] Working principle: when the fire hose needs to be reeled in, the stopper 407 on the surface of the pull block 406 is rotated out, and the pull block 406 is driven by the elastic force of the spring 409 to drive the plug block 405 to be inserted into the inner side of the slot 410 on the output shaft 404, so that the locking docking work between the rotating shaft 3 and the output shaft 404 can be realized. At this time, the motor 401 is started, and the motor 401 drives the output shaft 404 and the rotating shaft 3 to rotate, thereby improving the winding efficiency of the fire hose on the rotating shaft 3. When the fire hose needs to be taken, the pull block 406 is pulled, and the pull block 406 drives the plug block 405 from The inner side of the slot 410 is pulled out, and the stopper 407 on the connecting plate 408 is rotated at this time. The stopper 407 blocks the surface of the pulling block 406, which can realize temporary support work for the pulling block 406 and the inserting block 405 after moving. At this time, the rotating shaft 3 will be free from the constraint of the output shaft 404, which is convenient for taking out the fire hose on the winding roller 2. By setting the control structure 4, the flexible driving and rotating work of the rotating shaft 3 by automatic and manual twisting is facilitated, the flexibility of driving the rotating shaft 3 is improved, and the flexibility of retracting and releasing the fire hose on the winding roller 2 is improved to a certain extent, and the use efficiency of the winding device is improved.

[0035] When the fire hose needs to be reeled in, the fire hose is placed between two adjacent rollers 51, and the driving rod 55 is rotated to drive the slider 54 inside the positioning plate 52, thereby facilitating the adjustment of the clamping force of the fire hose. In the process of pulling the fire hose, the roller 51 rotates on the surface of the circular rod 53 to reduce the large friction generated during the movement of the fire hose, thereby increasing the resistance to the pulling of the fire hose, and the water will be squeezed out by the two rollers 51, thereby improving the effect of reeling in the fire hose. By setting the compression structure 5, the extrusion of the water inside the fire hose during the reeling in of the fire hose is facilitated, thereby further improving the reeling efficiency of the fire hose.
