Description

Technical Field

[0001] This utility model relates to the field of fire equipment maintenance technology, specifically a fire hose cleaning reel device. Background Technology

[0002] Fire hoses are critical transport equipment in firefighting and rescue operations. After routine training and firefighting operations, their outer surface is often contaminated with a large amount of mud, oil, chemical residues, or other flammable materials. If these contaminants are not cleaned thoroughly and promptly, they will not only corrode the outer layer of the hose and shorten its service life, but will also damage the sealing of the hose joints due to friction or adhering impurities during the next use, and may even become a safety hazard in emergency situations.

[0003] Currently, the cleaning of fire hoses still largely relies on traditional manual methods. Operators typically use a handheld high-pressure water gun for initial rinsing, followed by manual scrubbing with a brush, and finally manually storing the cleaned hose reels. This method has several significant drawbacks:

[0004] (1) Low cleaning efficiency and high labor intensity: It relies entirely on manpower, and the cleaning speed is slow. In particular, for cleaning large quantities of long-distance water hoses, a lot of manpower and time are required, which is difficult to meet the needs of fire brigades to quickly dispatch and return to the station for equipment maintenance.

[0005] (2) Uneven cleaning effect and difficulty in guaranteeing quality: The strength and frequency of manual brushing cannot be consistent, which can easily lead to blind spots in cleaning, resulting in some stubborn stains not being completely removed and affecting the cleaning quality.

[0006] (3) Low level of automation and poor integration: The rinsing, brushing and reeling processes are independent of each other, and the operation is cumbersome and requires the cooperation of many people. Some existing cleaning equipment has only one function, such as rinsing or reeling, and cannot realize the integrated operation of cleaning, dehydration and reeling. The water hose is prone to secondary pollution or wear during the transfer process after cleaning.

[0007] (4) Safety hazards exist: During manual cleaning, operators may come into close contact with dirt that may contain chemical corrosives or harmful organisms, and improper operation of high-pressure water guns may cause injury to personnel.

[0008] Although some experimental mechanical cleaning devices have emerged, they are usually complex in structure, not very targeted, or unable to effectively treat the upper and lower surfaces of the hose at the same time. In particular, the design of the scrubbing unit lacks an easy-to-adjust and maintain structure, and cannot adapt well to hoses with different levels and thicknesses of dirt. Their reliability and practicality need to be improved. Utility Model Content

[0009] To overcome the shortcomings of the prior art, this utility model provides a fire hose cleaning reel device that integrates automatic rinsing, brushing, and reeling, resulting in high cleaning efficiency, excellent effect, and simple operation.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A fire hose cleaning reel device includes a frame, a reel mechanism, a cleaning assembly, and a guide support mechanism; the reel mechanism is mounted on the frame and is used to wind the fire hose; the cleaning assembly includes a rinsing mechanism and a brushing mechanism, the rinsing mechanism having nozzles facing the upper and lower surfaces of the fire hose to rinse the upper and lower surfaces of the fire hose.

[0012] The brushing mechanism includes a brushing motor and an upper brush roller and a lower brush roller arranged opposite each other. The upper brush roller is hinged to the frame and can rotate up and down, while the lower brush roller is fixed to the frame. The brushing motor drives the upper and lower brush rollers to rotate synchronously in opposite directions through a transmission component. The guide support mechanism is set on the frame and located between the reel mechanism and the cleaning assembly, and is used to guide and support the fire hose.

[0013] Furthermore, the reel mechanism includes a turntable, winding rods, and a fixing assembly; a pair of winding rods are fixedly connected to the turntable in parallel, and a gap is formed between the winding rods for securing the fire hose; the fixing assembly includes a fixing tube corresponding to the winding rod, which is inserted into the winding rod to limit the fire hose in the gap.

[0014] Furthermore, the fixing assembly also includes an operating handle, which is D-shaped, and the fixing tube is fixed to the straight rod portion of the D-shaped operating handle.

[0015] Furthermore, it also includes a reel motor, which is connected to the turntable and drives the reel to rotate.

[0016] Furthermore, the flushing mechanism includes a water supply pipeline with an on / off control valve connected in series on the pipeline, and the inlet end of the water supply pipeline is connected to an external pressure water source.

[0017] Furthermore, the transmission assembly includes an upper gear, a lower gear, and a drive gear. The upper gear is installed at the end of the upper brush roller shaft, and the lower gear is installed at the end of the lower brush roller shaft. The upper gear meshes with the lower gear, and the drive gear meshes with the lower gear. The drive gear is connected to the brushing motor, and the brushing motor drives the drive gear, the lower gear, and the upper gear to rotate synchronously.

[0018] Furthermore, the brushing mechanism also includes a hinge assembly and a quick-lock assembly; one end of the upper brush roller is rotatably connected to the frame via the hinge assembly; the other end of the upper brush roller is provided with the quick-lock assembly; the quick-lock assembly includes a cooperating moving part and a fixed part, the moving part is disposed on the upper brush roller, and the fixed part is disposed on the frame; the upper brush roller has a working position, when in the working position, the moving part engages with the fixed part to lock the upper brush roller; when the moving part separates from the fixed part, the upper brush roller can rotate and flip up around the hinge assembly.

[0019] Furthermore, a lifting ring is fixedly provided on the moving part.

[0020] Furthermore, the guide support mechanism includes at least one support roller, which is hinged to the frame via bearings.

[0021] Furthermore, it also includes a limiting mechanism, which is disposed between the guide support mechanism and the cleaning assembly. The limiting mechanism includes a rotating shaft and a limiting disc. A pair of limiting discs are fixedly connected to the rotating shaft in parallel with each other. A guide channel for lateral limiting of the fire hose is formed between the two limiting discs. The rotating shaft is hinged to the frame through a bearing.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. This utility model integrates a reel mechanism, a cleaning assembly, and a guide support mechanism, achieving fully automated operation from hose introduction and double-sided cleaning to automatic reel winding. Compared to traditional manual operation, efficiency is increased several times, significantly reducing labor intensity. It employs a multi-stage collaborative cleaning mechanism combining high-pressure rinsing and mechanical brushing. After initial rinsing by upper and lower opposing nozzles, deep cleaning is performed by synchronously rotating upper and lower brush rollers, effectively removing surface and stubborn stains. The cleaning effect is thorough and uniform, which helps extend the service life of the hose. Furthermore, the upper brush roller adopts a hinged, flip-up design, enabling quick opening and closing. When open, the hose can be easily placed; when closed, a stable cleaning channel is formed. Combined with the precise positioning of the guide support mechanism, it effectively prevents hose deviation and wrinkling, ensuring the stability and safety of equipment operation. This device has a reasonable structure, is easy to operate, and has good adaptability and promotional value.

[0024] 2. The hose reel fixing mechanism is highly efficient, reliable, and easy to operate: By using parallel winding rods to create a locking gap, and in conjunction with an insertable fixing tube, the end of the fire hose is quickly positioned and reliably fixed. The specially added D-shaped operating handle is ergonomic, making it easier and less strenuous for operators to insert and remove the fixing tube, significantly improving the efficiency of hose loading and unloading, and effectively avoiding the risk of detachment due to insecure fixing.

[0025] 3. The drive and transmission system has a compact structure and strong synchronization: The reel motor automates the winding process and ensures stable water belt conveying speed. The brushing mechanism uses meshing upper and lower gears as transmission components, ensuring precise synchronous rotation of the upper and lower brush rollers, thus forming a highly efficient "scrubbing" effect. The cleaning power transmission is reliable, the structure is compact, and the operation is smooth.

[0026] 4. The upper brush roller locking and flipping mechanism features an ingenious design, offering high safety and ease of use: The combination of the hinged and quick-lock components allows the upper brush roller to be quickly flipped open for placing the water hose and performing equipment maintenance, while also being securely locked in the working position, ensuring the safety and stability of the cleaning process. The lifting ring on the moving part provides the operator with a clear point of force application, making opening and closing the brush roller exceptionally easy, greatly improving the equipment's usability and human-machine interface.

[0027] 5. Comprehensive hose guiding and limiting system with excellent operational stability: The support rollers in the guiding support mechanism provide flexible rotational support for the hose, effectively reducing frictional resistance during conveying. The added limiting mechanism, through a guide channel formed by two limiting discs, effectively prevents the hose from lateral deviation or twisting during cleaning, ensuring that the hose always passes smoothly through the cleaning area along the preset path. This is crucial for ensuring uniform cleaning results and continuous, reliable equipment operation. Attached Figure Description

The fixing pipe 23 is welded to the straight rod of the D-shaped operating handle 24 and is inserted into the two winding rods 22 to limit and fix the end of the hose. The reel motor 8 drives the reel mechanism 2. The reel motor 8 is connected to the turntable 21 and fixed to the frame 1. The turntable 21 is fixed to the output shaft of the reel motor 8. The reel motor 8 drives the turntable 21 to rotate to complete the reeling operation.

[0046] The guide support mechanism 4 is installed in the middle of the frame 1, between the reel mechanism 2 and the cleaning assembly 3. The guide support mechanism 4 includes a support roller 41 mounted on the frame 1 via bearings, which supports and guides the fire hose 9. The limiting mechanism 5 is located on the right side of the guide support mechanism 4, adjacent to it. The limiting mechanism 5 includes a rotating shaft 51 mounted on the frame 1 via bearings and a pair of limiting discs 52 fixed parallel to the rotating shaft 51. The two limiting discs 52 form a guide channel for laterally limiting the hose.

[0047] The cleaning assembly 3 includes a rinsing mechanism 31 and a brushing mechanism 32. For example... Figure 5 As shown, the flushing mechanism 31 is located at the limiting mechanism 5. The flushing mechanism 31 consists of a water supply pipe 312, an on / off control valve 313, and sprinklers 311 symmetrically arranged vertically. The sprinklers 311 include an upper sprinkler and a lower sprinkler. The upper sprinkler is angled downwards, and the lower sprinkler is angled upwards, both facing the fire hose 9.
