Fires are very likely to occur in the summer, and densely populated residential areas have led to an increasingly severe fire situation. Fire protection issues are receiving more and more attention.

[0003] Fire hoses are soft pipes used to transport high-pressure water or flame-retardant liquids such as foam. They are essential water pipes for firefighting and rescue. Generally speaking, the length of a fire hose is between 20 and 25 meters. Its outer layer is a round tube fabric made of chemical fiber materials such as polyester and polyester-cotton. The lining of the hose is a sulfide layer or coating that prevents water leakage. When a fire occurs, you need to quickly connect the fire hose to the fire hydrant, then turn on the water valve switch to let the fire hose discharge water.

[0004] After the firefighting work is completed, the fire hose needs to be rolled up for storage, but currently most of them are rolled up manually, which is inconvenient; in addition, a small amount of water is still contained in the fire hose that has just been used, which makes the hose heavy and more laborious to roll up. The water needs to be drained out before rolling it up, and the manual drainage speed is slow, resulting in a waste of human resources. Utility Model Content

[0033] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 As shown, the embodiment of the utility model provides a fire hose reeling device, comprising a base 1 and a reeling assembly 2 and a drainage assembly 3 installed on the base 1;

[0035] The winding assembly 2 includes a winding shaft 21, a pair of mutually symmetrical retaining rings 22 and a winding frame 23, wherein the retaining rings 22 include a first retaining ring 221 and a second retaining ring 222, and the winding frame 23 is a triangular structure, and its left and right ends are respectively connected to the first retaining ring 221 and the second retaining ring 222 through a fixing seat 4;

[0036] The drainage assembly 3 includes a squeezing roller 31 and a pair of pillars 32, wherein the squeezing roller 31 is installed between the two pillars 32 and is rotatably connected to the two pillars 32;

[0037] The winding shaft 21 is connected to the first retaining ring 221 and the second retaining ring 222 through a rotating shaft;

[0038] The squeezing roller 31 includes an upward squeezing roller 311 and a downward squeezing roller 312. The upward squeezing roller 311 includes two squeezing rollers, and the downward squeezing roller 312 includes one squeezing roller. The squeezing rollers 31 are parallel to each other and form an inverted triangle structure in the vertical direction. An squeezing channel for the fire hose to pass through is formed between the upward squeezing roller 311 and the downward squeezing roller 312, and the width of the squeezing channel is less than the thickness of the hose.

[0039] Specifically, a plurality of connecting rods are provided in the first retaining ring 221 and the second retaining ring 222, so that the rolled-up water hose can be exposed to air to a greater extent, which is conducive to rapid drying of the water hose.

[0040] It should be noted that the height of the extrusion channel formed by the upward extrusion roller 311 and the downward extrusion roller 312 is not higher than the height of the winding shaft 21 to prevent the squeezed water from flowing to the water hose on the wound side; preferably, the extrusion channel is on the same horizontal line as the winding shaft 21.

[0041] When in use, the fire hose is first passed through the extrusion channel and then wound around the reel 21. As the reel 21 rotates, the hose gradually passes through the extrusion channel, causing the residual liquid in the hose to flow to the unreeled side hose, ensuring that there is almost no residual liquid in the reeled hose, and the residual liquid in the hose is discharged while reeling.

[0042] Furthermore, an I-shaped card interface 321 is provided on the pair of pillars 32, and corresponding card connection structures 5 are connected to both ends of the downward squeezing roller 312 for moving the downward squeezing roller 312 to adjust the width of the squeezing channel so that the fire hose port can successfully pass through the squeezing channel.

[0043] Specifically, the clamping structure 5 includes a pair of clamping blocks 51 and a fixed rod 52, and the pair of clamping blocks 51 are slidably connected to the two ends of the fixed rod 52 respectively; the fixed rod 52 is a hollow structure with a built-in telescopic spring, and the telescopic spring passes through the fixed rod 52 to the inside of the clamping block 51. When the telescopic spring is extended or compressed, the length and height of the clamping block 51 and the fixed rod 52 are adapted to the I-shaped clamping interface 321.

[0044] When the telescopic spring is freely extended, the length and height of the clamping block 51 and the fixing rod 52 are adapted to the two ends of the I-shaped clamping interface 321; when the telescopic spring is compressed, the length of the clamping block 51 and the fixing rod 52 are adapted to the middle part of the I-shaped clamping interface 321.

[0045] When in use, the two paired clamping blocks 51 at both ends of the downward squeezing roller 312 are pressed respectively to shrink the spring, and the clamping structure 5 can pass through the middle part of the I-shaped clamping interface 321 and move from the upper end to the lower end of the I shape, thereby driving the downward squeezing roller 312 to move downward, enlarging the squeezing channel, and after the fire hose port successfully passes through the squeezing channel and is wound on the winding shaft 21, the two paired clamping blocks 51 at both ends of the downward squeezing roller 312 are pressed again, and the clamping structure 5 passes through the middle part of the I-shaped clamping interface 321 and returns to the upper end, shrinking the squeezing channel, so that the upward squeezing roller 311 and the downward squeezing roller 312 squeeze the fire hose, thereby promoting the discharge of residual liquid in the hose.

[0046] In order to prevent the downward squeezing roller 312 from moving horizontally, grooves are provided on the sides of the clamping block 51 , and the width of the grooves is matched with the width of the pillars 32 .

[0047] Furthermore, the rotating shaft passes through the first retaining ring 221 and is connected to the rocker 6, so that rotating the rocker 6 can drive the winding shaft 21 to rotate, which is more labor-saving. A first anti-slip sleeve 61 is provided on the rocker 6 to prevent the rocker 6 from slipping after being wet.

[0048] In order to facilitate the movement of the winding device, a universal wheel 7 is provided under the base 1.

[0049] Specifically, a brake 71 is provided on the universal wheel 7 to prevent the device from sliding during the winding operation.

[0050] Furthermore, the base 1 is provided with a slide rail along its length direction, and a horizontally slidable gravity block 8 is provided on the slide rail. The position of the gravity block can be adjusted according to the weight of the wound water hose to prevent the base 2 from tipping over due to uneven force.

[0051] Specifically, the length of the slide rail is the length from the winding component 2 to the drainage component 3.

[0052] Furthermore, an armrest 9 is provided on the side of the base 1 to facilitate the movement of the device. The armrest 9 is rotatably connected to the base 1 to facilitate different users to adjust the angle suitable for their use.

[0053] Specifically, the handrail 9 is provided with a second anti-slip cover 91 to prevent the handrail 9 from slipping after getting wet, which is inconvenient to use; at the same time, the handrail 9 can be placed on the fire hose to be rolled up, which makes it more convenient to roll up and also promotes the residual liquid to flow to the side of the fire hose to be rolled up.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
