Description

Technical Field

[0001] This utility model relates to the field of fire hose technology, specifically a portable fire hose. Background Technology

[0002] Fire hoses are flexible hoses used to transport high-pressure water or flame-retardant liquids such as foam. They are a core component of fire extinguishing systems, and their performance directly affects fire extinguishing efficiency. Portable fire hoses are lightweight and easy to carry. While existing hose winding techniques facilitate pipe winding, their simple structure makes it cumbersome to wind the hose after use and prevents the water inside from being drained, hindering firefighters' reuse. A portable fire hose with announcement number CN220090342U, through the cooperation of a first and second drainage roller, can squeeze out residual liquid from the hose, facilitating hose storage. A hose head storage seat facilitates the placement of the hose head and allows for easy unwinding. A handle and anchor on the top of the first bracket allow the device to be hung on a vehicle for easy transport. A large and small gear achieves a speed reduction and power increase effect, facilitating manual hose winding.

[0003] While the aforementioned technology can squeeze out residual liquid from the hose, making it easier to store, it has the problem of not being able to clean the fire hose itself during storage. The hose lining is in constant contact with moisture, making it prone to hydrolysis and mold growth. The outer woven fibers absorb water and swell, leading to a decrease in fiber strength. Furthermore, the surface of the hose may contain hard objects such as mud, sand, and gravel, which will rub against the inner and outer fibers during storage. In humid environments, the mud, sand, and organic residue become a breeding ground for bacteria and mold, especially in the folds of the hose, where black spots are easily formed. Utility Model Content

[0004] The purpose of this utility model is to provide a portable fire hose to solve the problem mentioned in the background art that fire hoses on the market cannot be cleaned during storage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable fire hose, comprising a first support plate, a base plate at the bottom of the first support plate, and a second support plate movably abutting at the other end of the top of the base plate; a fire hose body is provided between the second support plate and the first support plate; rotating shafts are rotatably connected to all four sides of one side of the first support plate, and the two rotating shafts on both sides are connected by a synchronous belt; hollow columns are rotatably connected to all four sides of one side of the second support plate; a first hexagonal prism is slidably connected to one end of each of the four rotating shafts inside the four hollow columns; cleaning blocks are provided around all four rotating shafts; a winding assembly for winding the fire hose body is provided on the first support plate; a squeezing assembly for squeezing the water inside the fire hose body is provided between the first support plate and the second support plate; and a connecting assembly for connecting the second support plate and the first support plate is provided on the second support plate.

[0006] Preferably, the winding assembly includes a winding roller rotatably connected inside a first support plate, a hollow disc rotatably connected inside the second support plate, a second hexagonal prism slidably connected inside the hollow disc at one end of the winding roller, a rotating column at the other end of the winding roller, and a turntable at one end of the rotating column.

[0007] Preferably, four support blocks are provided on one side of the first support plate, and rotating rods are rotatably connected between the two support blocks on both sides. One end of the two rotating rods and one end of the rotating column are respectively provided with a first bevel gear that meshes with each other, and the other end of the two rotating rods and one end of the two rotating shafts are respectively provided with a second bevel gear that meshes with each other.

[0008] Preferably, the extrusion assembly includes four extrusion strips slidably connected around the periphery of the first support plate, and a first spring is provided between one end of each of the four extrusion strips and the interior of the periphery of the first support plate. Hollow blocks are also slidably connected around the periphery of the second support plate, and a second spring is provided between one end of each of the four hollow blocks and the interior of the periphery of the second support plate. A protrusion is slidably connected inside the hollow block at one end of each of the four extrusion strips, and an eccentric wheel is provided at both ends of each of the four rotating shafts.

[0009] Preferably, the connecting assembly includes four connecting strips respectively disposed around the second support plate, and locking screws are threadedly connected around the first support plate, with the four locking screws respectively threaded inside the four connecting strips.

[0010] Preferably, the upper part of both the first support plate and the second support plate is provided with a slot, and the two ends of the second support plate away from the first support plate are provided with hooks.

[0011] Preferably, each of the four extrusion strips has an extrusion pad on one side, and the cleaning blocks are all made of elastic material.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By rotating the rotating shaft, the cleaning block is driven to rotate on the surface of the fire hose body, achieving the effect of cleaning the fire hose body when it is stored. After removing surface stains and moisture, the friction coefficient of the outer layer of the hose is reduced, and it is not easy to wrinkle or knot due to adhesion when winding. It can form a tight reel structure and reduce the storage volume.

[0014] The built-in winding component allows for the winding and storage of the fire hose when it is not in use, making it easy to carry. By tightly winding the hose, it is compressed into a disc shape, reducing its size so that it can be carried by hand, on the back, or mounted on fire trucks and equipment racks, while also saving space.

[0015] By using the compression components, the water inside the fire hose is squeezed out when it is stored, which removes residual water and significantly reduces the total weight after storage. This makes it easier for a single person to carry, drag, or hand-lift the hose, achieving the need for lightweighting. It also allows the hose diameter to be reduced further, saving storage space.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides the following technical solution: a portable fire hose.

[0026] Example 1: To solve the problem of existing fire hoses being difficult to clean during storage, the following is disclosed: a first support plate 1, with a base plate at its bottom, and a second support plate 2 movably abutting at the other end of the top of the base plate; a fire hose body 4 (e.g., ...) is provided between the second support plate 2 and the first support plate 1. Figures 1-4 and Figure 6 As shown), rotating shafts 5 are rotatably connected to all four sides of one side of the first support plate 1, and the two rotating shafts 5 on both sides are connected by a synchronous belt. Hollow columns 6 (as shown) are rotatably connected to all four sides of one side of the second support plate 2. Figure 7 As shown), one end of each of the four rotating shafts 5 is provided with a first hexagonal prism that is slidably connected to the inside of the four hollow pillars 6, and cleaning blocks 7 are provided around the four rotating shafts 5 (as shown). Figures 1-6 As shown), a winding assembly is used to clean the surface of the fire hose body 4. The first support plate 1 is equipped with a winding assembly for winding the fire hose body 4. The winding assembly includes a winding roller 3 rotatably connected inside the first support plate 1 for winding the fire hose body 4. A hollow disc 13 is rotatably connected inside the second support plate 2. One end of the winding roller 3 is provided with a second hexagonal prism slidably connected inside the hollow disc 13, and the other end of the winding roller 3 is provided with a rotating column 8. One end of the rotating column 8 is provided with a turntable. Four support blocks are provided on one side of the first support plate 1, and rotating rods 9 are rotatably connected between the two support blocks on both sides. One end of each of the two rotating rods 9 and one end of the rotating column 8 are respectively provided with mutually meshing first bevel gears (such as...). Figure 3 As shown), the other ends of the two rotating rods 9 and one end of the two rotating shafts 5 are respectively provided with mutually meshing second bevel gears, and the upper parts of the first support plate 1 and the second support plate 2 are both provided with slots (such as...). Figure 2 As shown), hooks are provided at both ends of the second support plate 2 on the side away from the first support plate 1.

[0027] When it is necessary to wind up the fire hose body 4, the fire hose body 4 can be placed on the winding roller 3, and then the turntable (such as...) can be rotated. Figure 1 , Figure 3 and Figure 4As shown), this causes the rotating column 8 to rotate, which in turn drives the winding roller 3 to rotate, thus winding up the fire hose body 4. Simultaneously, the rotating column 8 rotates, and under the action of the first bevel gear, it drives the two rotating rods 9 to rotate. Then, under the action of the second bevel gear, it drives the two upper rotating shafts 5 to rotate. Subsequently, under the action of the synchronous belt (as shown...), the fire hose body 4 is wound up. Figure 6 As shown), this causes the two rotating shafts 5 below to rotate, thereby causing the cleaning block 7 to rotate on the surface of the fire hose body 4 and clean its surface. The hollow column 6 can provide support for the rotating shafts 5, and the first support plate 1 and the second support plate 2 have slots opened on the upper part (such as...). Figures 1-4 As shown in the figure, the first support plate 1 and the second support plate 2 are easy to carry. The second support plate 2 and the first support plate 1 can be hung in a suitable position by hook, so as to achieve the effect of making the fire hose body 4 easy to carry.

[0028] Example 2: Unlike Example 1, the compression assembly can squeeze out the water remaining inside the fire hose body 4. It discloses that: a compression assembly for squeezing the water inside the fire hose body 4 is provided between the first support plate 1 and the second support plate 2. A connecting assembly connecting the second support plate 2 and the first support plate 1 is provided on the second support plate 2. The compression assembly includes four compression strips 10 slidably connected around the first support plate 1, used to squeeze out the water remaining inside the fire hose body 4. A first spring is provided between one end of each of the four compression strips 10 and the interior of the first support plate 1. Hollow blocks 11 (such as...) are also slidably connected around the second support plate 2. Figure 7 As shown), one end of each of the four hollow blocks 11 is provided with a second spring between the interior of the second support plate 2 and one end of each of the four extrusion strips 10, which are slidably connected to the interior of the hollow blocks 11. Eccentric wheels 12 are provided at both ends of the four rotating shafts 5 to push the extrusion strips 10 to move. The connecting assembly includes four connecting strips 14 (as shown) respectively arranged around the second support plate 2. Figures 1-4 As shown), the first support plate 1 is threaded with locking screws on all four sides, and the four locking screws are respectively threaded into the four connecting strips 14, which facilitates the disassembly of the second support plate 2. Each of the four pressing strips 10 has a pressing pad on one side (such as...). Figure 6 As shown), all cleaning blocks 7 are made of elastic material.

[0029] The two ends of the fire hose body 4 are placed between the compression strips 10. As the fire hose body 4 is wound up, it slides on the surface of the compression strips 10, thereby squeezing out the water remaining inside. When the rotating shaft 5 rotates, it also drives the eccentric wheel 12 to rotate (e.g., Figures 1-6As shown), this intermittently pushes the extrusion bar 10, which then slides inside the first support plate 1, compressing the first spring. Subsequently, under the action of the protrusion, it also drives the hollow block 11 to slide inside the second support plate 2, compressing the second spring (as shown). Figure 7 As shown), the compression strip 10 moves back and forth on the surface of the fire hose body 4, thereby improving the compression effect. When the fire hose body 4 is needed, the locking screw can be turned to move it away from the connecting strip 14, so that the second support plate 2 can move away from the first support plate 1, and the fire hose body 4 can be taken out for use. The compression pad can reduce the wear of the fire hose body 4, and the elastic cleaning block 7 can better fit the fire hose body 4.
