Description

Technical Field

[0001] This invention relates to fire protection, and more specifically to the field of fire hose accessories, specifically a fire hose reel designed to prevent water accumulation. Background Technology

[0002] Fire hose reels are an important supporting facility for fire protection systems in buildings. They are widely used in the initial fire fighting of shopping malls, office buildings, residences and other places. They play a basic role in the emergency response of fires by providing rapid water supply and convenient operation. They are commonly used equipment to ensure public fire safety.

[0003] Most fire hose reels on the market today use a combination of a fixed reel and a rotating reel shaft. The hose is released and wound up manually. The hose is directly wound around the reel shaft, and the winding and releasing process is completed by the deformation of the hose itself. Drainage and positioning both rely on manual operation. The overall structure is mainly based on basic winding function and does not have a dedicated linkage control and status locking mechanism.

[0004] Existing fire hose reels have obvious defects in actual use. After the hose is wound up, the residual water inside the hose cannot be discharged on its own. Long-term accumulation can easily cause the pipeline to freeze and crack, the inner wall to rust and the channel to be blocked. In use, there is no reliable positioning and locking structure, which can easily lead to unwinding and rebound and the hose body to become disordered. The hose winding and unwinding process lacks stable guiding constraints, which can easily cause uneven wear, twisting and entanglement. It is difficult to meet the requirements for stable and reliable use. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a water-proof fire hose reel that solves the problems of water accumulation inside the hose after winding up, easy loosening and rebound during use, and easy wear and tangling during hose winding and unwinding.

[0007] Preferably, the reel assembly further includes a reel shaft, which is rotatably connected between two outer reels and two inner reels. The axis of the reel shaft is aligned with the axes of the two outer reels and the two inner reels. The reel mounting bracket has a U-shaped structure, and its two lugs are fixedly connected to the two outer reels respectively. The outer reels are fixedly connected to the inner reels on the same side.

[0008] Preferably, one end of the tube reel is connected to a water inlet pipe, one side of the reel mounting bracket is connected to a clamp, the water inlet pipe is clamped onto the clamp, a flexible tube is connected to the tube reel, the flexible tube is wound around the tube reel, the flexible tube is located between two inner reels, and the movable end of the flexible tube passes between two counterweight rollers.

[0009] Preferably, the anti-water accumulation component further includes a slider integrally connected to each support arm, and a groove corresponding to the slider is provided on the side of each of the two inner reels that are far apart from each other. The groove is an arc-shaped structure, and the two support arms on the same side are staggered.

[0010] Preferably, the limiting component includes an external toothed ring, which is rotatably sleeved on one end of the winding tube shaft. A rocker arm is integrally connected to the external toothed ring, and a support plate is fixedly connected to the end of the rocker arm. The support plate has an arc-shaped structure and moves along the circumferential curve of the inner winding reel.

[0011] Preferably, a sliding rod is slidably passed through the support plate, one end of the sliding rod is fixedly connected to a limiting head, a tension spring is elastically connected between the limiting head and the outer arc surface of the support plate, and a pressure plate is fixedly connected to the other end of the sliding rod.

[0012] Preferably, a connecting shaft is fixedly connected to the outer wall of the slide rod, and a retaining shaft is hinged to the connecting shaft. The end face of the retaining shaft is a wedge-shaped structure, and a return spring is elastically connected between the connecting shaft and the retaining shaft.

[0013] Preferably, there are two limiting components, which are symmetrically and staggered with each other. The external toothed rings in the two limiting components are sequentially rotated and sleeved on the same end of the winding tube shaft, and the two external toothed rings respectively mesh with two gears.

[0014] Preferably, the guide assembly includes a support rod with two sleeves. One sleeve is fixedly connected to one end of the support rod, and the other sleeve is rotatably fitted onto the other end of the support rod. A torsion spring is elastically connected between the two sleeves. A swing arm is fixedly connected to the other sleeve, and a guide wheel is fixedly connected to one end of the swing arm.

[0015] Preferably, there are two guide components, which are arranged symmetrically to each other. The support rods in both guide components are fixedly connected to one side of the inner reel. The guide wheels in both guide components abut against the flexible reel. The other ends of the swing arms in both guide components abut against the retaining pins on the same side.

[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides a fire hose reel that prevents water accumulation, and has the following beneficial effects: 1. By coordinating the counterweight roller, support arm, slider, and chute structure, and utilizing the linkage mechanism of water injection expansion separating the counterweight roller during soft hose reeling and the counterweight roller relying on its own weight to close and squeeze the soft hose reel during winding, the residual water inside the hose reel can be automatically discharged during the winding process. This is different from the existing fire hose reel structure that cannot discharge water independently, and solves the technical problem that water accumulation inside the hose can easily cause freezing, cracking, corrosion, and blockage, thereby improving the reliability and service life of the fire hose reel.

[0017] 2. By linking gears, external gear rings, rocker arms, support plates, slide rods and pressure plate structures, the displacement caused by the expansion of the soft hose during water injection is converted into the action of pressure plate clamping and locking, realizing automatic mechanical positioning of the hose reel in the water injection state. This is different from the existing hose reels that do not have a locking mechanism in the use state. It solves the technical problems of easy loosening, rebound and hose body disorder during use, and improves the structural stability and operational safety during fire fighting operations.

[0018] 3. By using a combination of torsion springs, ferrules, swing arms and guide wheels, the winding and unwinding path of the soft hose is continuously limited and oriented. Unlike the existing design of reels which lacks a stable guiding mechanism, this design solves the technical problems of uneven wear, twisting and tangling that easily occur during the winding and unwinding of soft hoses. It ensures that the winding and unwinding actions of the soft hose are smooth and orderly, reduces wear on the hose body and improves the stability of equipment operation.

[0019] 4. By cooperating with the locking shaft, connecting shaft, return spring and swing arm structure, the mechanism automatically resets by using the wedge surface to avoid one direction and hold in the opposite direction. Unlike the existing operation method of reel that requires manual assistance to reset, it solves the technical problems of cumbersome reset steps and unreliable positioning after rewinding. It realizes the automated operation of the entire process of release, locking, drainage and reset without manual intervention, which simplifies the use process and reduces maintenance costs.

[0020] 5. By combining double outer reels, double inner reels, a reel shaft, and a flexible reel, a multi-layer stable support winding structure is formed. This differs from the existing single-layer reel bearing form and solves the technical problems of insufficient radial positioning and easy deviation and scattering during flexible reel winding. It improves the overall structural strength and winding regularity of the reel and is suitable for the high-frequency use requirements in fire protection scenarios. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1 - Figure 7 The present invention provides a fire hose reel with anti-water accumulation, including a hose reel mounting frame 1, a hose reel assembly 2 mounted on the hose reel mounting frame 1, an anti-water accumulation component 3 provided on the hose reel assembly 2, a limit component 4 provided on the anti-water accumulation component 3, and a guide component 5 provided on the limit component 4.

[0025] In use, the reel mounting bracket 1 is a fixed support structure, the reel assembly 2 realizes the winding and unwinding of the flexible reel 25, the anti-water accumulation component 3 squeezes the flexible reel 25 during the winding stage to discharge the water inside the pipe, the limiting component 4 locks the position of the reel assembly 2 during the water injection stage, and the guide component 5 provides guidance and limiting support during the winding and unwinding of the flexible reel 25.

[0026] Furthermore, the reel assembly 2 includes two outer reels 21 and two inner reels 22, which are symmetrically arranged. The two inner reels 22 are located between the two outer reels 21. The reel assembly 2 also includes a winding shaft 23, which is rotatably connected between the two outer reels 21 and the two inner reels 22. The axis of the winding shaft 23 is aligned with the axes of the two outer reels 21 and the two inner reels 22. The reel mounting bracket 1 has a U-shaped structure. The two ears of the frame 1 are fixedly connected to the two outer reels 21 respectively. The outer reels 21 are fixedly connected to the inner reels 22 on the same side. One end of the reel shaft 23 is connected to the water inlet pipe 24. The reel shaft 23 and the water inlet pipe 24 are connected by a rotary joint. One ear of the reel mounting frame 1 is connected to a clip. The water inlet pipe 24 is clipped onto the clip. A flexible reel 25 is connected to the reel shaft 23. The flexible reel 25 is wound around the reel shaft 23 and is located between the two inner reels 22.

[0027] In use, the outer reel 21, the inner reel 22 and the reel mounting bracket 1 are kept fixed, the tube shaft 23 can rotate around the axis, the water inlet pipe 24 is connected to the tube shaft 23 through a rotary joint to supply water, the soft tube 25 completes winding and unwinding with the rotation of the tube shaft 23, and the clamp plays a fixed and limiting role for the water inlet pipe 24.

[0028] In this embodiment, the anti-water accumulation component 3 includes a first rotating shaft 31, which is fixedly connected to one of the inner winding reels 22. Two sleeves 32 are rotatably mounted on the first rotating shaft 31. A second rotating shaft 33 is fixedly connected to the other inner winding reel 22. Two gears 34 (m=0.8) are rotatably mounted on the inner winding reel 22. Support arms 35 are fixedly connected to both sleeves 32 and both gears 34. Counterweight rollers 38 are rotatably connected between the ends of the support arms 35 on the sleeves 32 and between the support arms 35 on the gears 34. The movable end of the flexible tube 25 passes between the two counterweight rollers 38. The anti-water accumulation component 3 also includes a slider 36 integrally connected to each support arm 35. A groove 37 corresponding to the slider 36 is opened on the side of the two inner winding reels 22 that is far apart from each other. The groove 37 is an arc-shaped structure. The two support arms 35 on the same side are staggered.

[0029] When in use, when the flexible tube 25 is filled with water and expands, it pushes the two counterweight rollers 38 to separate from each other. The support arm 35 rotates around the rotating shaft 31 and the rotating shaft 33 with the sleeve 32 and the gear 34. The slider 36 moves in an arc along the sliding groove 37. After the flexible tube 25 drains water and shrinks, the counterweight rollers 38 drive the support arm 35 to return to its original position by their own weight. The two counterweight rollers 38 move closer to each other and squeeze the flexible tube 25.

[0030] It is worth noting that the limiting component 4 includes an external toothed ring 41 (m=0.8), which is rotatably sleeved on one end of the winding tube shaft 23. A rocker arm 42 is integrally connected to the external toothed ring 41, and a support plate 43 is fixedly connected to the end of the rocker arm 42. The support plate 43 has an arc-shaped structure and moves along the circumferential curve of the inner winding tube 22. A slide rod 44 slides through the support plate 43, and a limiting head 45 is fixedly connected to one end of the slide rod 44. A tension spring 46 (YL0.8×8×30, stiffness coefficient K1≈1.8N / mm) is elastically connected between the limiting head 45 and the outer arc surface of the support plate 43. The other end of the slide rod 44 is fixedly connected to a pressure plate 47. The outer wall of the slide rod 44 is fixedly connected to a connecting shaft 48. A retaining shaft 49 is hinged on the connecting shaft 48. The end face of the retaining shaft 49 is a wedge structure. A return spring (YY0.5×6×10, stiffness coefficient K2≈1.2N / mm) is elastically connected between the connecting shaft 48 and the retaining shaft 49. There are two limiting components 4. The two limiting components 4 are symmetrically arranged and staggered. The external toothed rings 41 in the two limiting components 4 are sequentially rotated and sleeved on the same end of the winding tube shaft 23. The two external toothed rings 41 are respectively meshed with two gears 34.

[0031] In use, the gear 34 rotates, driving the external gear ring 41 to rotate synchronously. The external gear ring 41 drives the support plate 43 to move around the inner winding disc 22 via the rocker arm 42. The tension spring 46 provides axial tension to the slide rod 44. The retaining shaft 49 remains coaxial with the connecting shaft 48 under the action of the return spring. The wedge structure can achieve unidirectional avoidance. The pressure plate 47 moves with the slide rod 44 to press and release the soft winding tube 25.

[0032] It is worth noting that the guide assembly 5 includes a support rod 51, on which two retaining sleeves 52 are provided. One retaining sleeve 52 is fixedly connected to one end of the support rod 51, and the other retaining sleeve 52 is rotatably sleeved on the other end of the support rod 51. A torsion spring 53 (TN1.2×10×25, stiffness coefficient K3≈2.8N) is elastically connected between the two retaining sleeves 52. (mm / °), another ferrule 52 is fixedly connected to a swing arm 54, one end of the swing arm 54 is fixedly connected to a guide wheel 55, there are two guide components 5, the two guide components 5 are arranged symmetrically to each other, the support rods 51 in the two guide components 5 are fixedly connected to one side of the inner winding reel 22, the guide wheels 55 in the two guide components 5 are in contact with the flexible winding tube 25, and the other end of the swing arm 54 in the two guide components 5 is respectively in contact with the ferrule 49 on the same side.

[0033] In use, the support rod 51 is fixed on the inner winding reel 22 to provide support, and the torsion spring 53 provides torsional force to the rotating sleeve 52, so that the swing arm 54 drives the guide wheel 55 to continuously abut against the soft winding tube 25. The end of the swing arm 54 abuts against the locking shaft 49, pushing the slide rod 44 to slide along the support plate 43, realizing the linkage between the limiting component 4 and the guiding component 5. The torsion spring 53 is selected with a stiffness coefficient of K3, and the tension spring 46 is selected with a stiffness coefficient of K1. According to the spring force balance characteristics, the elastic torque of the torsion spring 53 is greater than the axial tension of the tension spring 46, which can realize that the torsion spring 53 pushes the swing arm 54 and drives the slide rod 44 to move upward, while the tension of the tension spring 46 cannot drive the torsion spring 53 to rotate, ensuring that the guiding, locking and resetting actions are transmitted unidirectionally according to the preset path.

[0034] Working principle: The reel mounting frame 1 serves as a fixed support base. The outer reel 21 and inner reel 22 are rigidly fixed to the reel mounting frame 1. The tube shaft 23 is connected to the water inlet pipe 24 through a rotary joint and can rotate freely relative to the inner reel 22 and outer reel 21. The soft tube 25 is regularly wound on the tube shaft 23, and its movable end passes through the two sets of counterweight rollers 38 to form a constraint path. When an external force pulls the soft tube 25, the soft tube 25 drives the tube shaft 23 to rotate synchronously to achieve orderly release.

[0035] During this process, the support rod 51 of the guide assembly 5 remains fixed, and the torsion spring 53 continuously applies elastic torque to the ferrule 52 and the swing arm 54, so that the guide wheel 55 always fits against the outer wall of the soft coil tube 25 to achieve directional guidance and radial limitation. The end of the swing arm 54 continuously pushes the retaining shaft 49 of the limiting assembly 4, pushing the slide rod 44 to slide upward along the support plate 43, driving the pressure plate 47 away from the soft coil tube 25 and the coil tube shaft 23, avoiding pressing interference to ensure smooth and stable release action.

[0036] When the inlet pipe 24 supplies water to the inside of the coiled tube shaft 23 and the flexible coiled tube 25, the flexible coiled tube 25 expands radially under water pressure. The expansion thrust acts on the two sets of counterweight rollers 38 and drives them to separate radially. The counterweight rollers 38 drive the support arms 35 to rotate around the first rotating shaft 31 and the second rotating shaft 33 respectively. The slider 36, which is integrally connected to the support arms 35, makes a directional arc movement along the arc-shaped groove 37 on the inner coiled tube 22. At the same time, the gear 34 rotates synchronously with the support arms 35 and drives the meshing gears. The external gear ring 41 rotates circumferentially around the winding tube shaft 23. The external gear ring 41 drives the support plate 43 to make curved displacement along the outer circumference of the inner winding reel 22 through the rocker arm 42. After the locking shaft 49 moves with the support plate 43, it disengages from the supporting action of the swing arm 54. Under the elastic tension of the tension spring 46, the slide rod 44 slides downward along the support plate 43, driving the pressure plate 47 to press the winding tube shaft 23, thereby realizing the rotation constraint of the winding tube shaft 23 and the overall mechanical locking of the winding reel, preventing problems such as loose winding, springback, and slippage during use.

[0037] After the firefighting operation is completed and the water supply is stopped, the water pressure inside the flexible hose 25 decreases and it contracts radially. Under its own weight, the two sets of counterweight rollers 38 drive the support arm 35, slider 36, and gear 34 to reset along the slide groove 37. The counterweight rollers 38 continuously close and squeeze the wall of the flexible hose 25, and the pressure plate 47 continuously presses against the wound tube body, forcibly expelling the residual water inside the tube completely from the movable end. During the reverse winding process of the flexible hose 25, as the number of winding layers increases, the outer diameter of the tube wall gradually increases and pushes the pressure plate 47 upward. The pressure plate 47 drives the slide rod 44 and the limiter. The head 45 moves upward and stretches the tension spring 46 to store energy. The retaining shaft 49 moves upward synchronously with the slide rod 44. The wedge surface of the end face of the retaining shaft 49 forms a one-way avoidance fit with the end of the swing arm 54. After the swing arm 54 slides along the wedge surface and passes over the retaining shaft 49, the retaining shaft 49 quickly returns to the coaxial state with the connecting shaft 48 under the action of the return spring. The end of the swing arm 54 is stuck below the retaining shaft 49 to form a reverse limit, preventing the retaining shaft 49 and the slide rod 44 from resetting downward. At the same time, the guide wheel 55 re-fits the outer wall of the soft coil tube 25 under the action of the torsion spring 53, restoring the initial guiding and limiting state.

[0038] The entire device uses a purely mechanical structure to achieve fully automated operation of the soft coil 25 release guide, automatic water injection locking, forced drainage during winding, and self-locking position reset, without the need for external power or manual intervention.
