DETAILED DESCRIPTION

[0018] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. However, this embodiment is not intended to limit the present invention. Any similar structure and similar variations of the present invention should be included in the scope of protection of the present invention.

[0019] like Figure 1 As shown, an automatic fire hose cleaning device includes a frame 1, on which a reeling mechanism 2 is provided that moves up and down along the frame. The fire hose is clamped and fixed on the reeling mechanism 2, and the reeling mechanism 2 drives the fire hose to move up and down. The reeling mechanism 2 and the frame 1 are the same as the structure of a fire hose automatic drying and reeling machine disclosed in Chinese utility model patent CN 210612755 U. The reeling mechanism 2 can be used to fix and clamp the fire hose and drive the fire hose to move up and down along the frame 1. Figure 1 、 Figure 2 and Figure 3 As shown, the lower section of the frame 1 is provided with a flushing mechanism and a brush roller mechanism, sequentially from top to bottom. The fire hose passes through the flushing mechanism and the brush roller mechanism for cleaning. During use, the reeling mechanism 2 moves downward along the frame 1, and the middle of the fire hose is hung on the reeling mechanism 2 and secured. The reeling mechanism then moves upward, causing the fire hose to suspend. The flushing mechanism flushes the fire hose, while the brush roller mechanism scrubs the fire hose. The brush roller mechanism not only scrubs the fire hose, but also clamps and secures the lower end of the fire hose, facilitating flushing by the flushing mechanism.

[0020] Specifically, such as Figure 1-Figure 3 As shown, the flushing mechanism includes an upper water pipe 5 and a water spray pipe 6. The lower end of the upper water pipe 5 is connected to a water supply device, and the upper end of the upper water pipe 5 is connected to a horizontally arranged water spray pipe 6. The water supply device includes a water tank 3 and a water pump. The water tank 3 is arranged outside the lower end of the frame 1. The lower end of the upper water pipe 5 is connected to the water tank 3 through the water pump. Alternatively, the water supply device is an external water source, and the external water source is connected to the lower end of the upper water pipe 5. The water spray pipe 6 is symmetrically arranged on the front and rear sides of the frame 1. The water spray pipe 6 is provided with a nozzle 7 arranged upwardly (the inclined nozzle is not shown in the drawings of the specification, and the nozzle is a high-pressure nozzle). The inclined upward nozzle not only overcomes the problem of water sinking due to gravity when it is sprayed, but also facilitates the flushing and removal of dust and debris due to the front and rear angles.

[0021] Regarding the brush roller mechanism, the frame 1 is provided with a bracket 8 that supports the brush roller mechanism. The brush roller mechanism includes a fixed brush roller 9 secured to the front bracket 8 and a movable brush roller 10 mounted on the rear bracket 8. The fixed brush roller 9 and movable brush roller 10 are coplanar and can rotate inward toward each other. One end of the fixed brush roller 9 is connected to the output of motor 11, which drives the fixed brush roller 9. As shown in the figure, motor 11 can be provided in a single set or symmetrically on both sides. The movable brush roller 10 is mounted at both ends on a cross-shaped slide bar 12. The rear upper end of the slide bar 12 is secured to a push plate 13, and the lower end of the slide bar 12 is slidably mounted on a support plate 14 of the frame 8. The support plate 14 has a slot 15 corresponding to the slide bar 12. The push plate 13 is provided with a second motor 16. The output end of the second motor 16 is connected to the shaft end of the movable brush roller 10 via a belt 17, which drives the movable brush roller 10.

[0022] The mobile brush roller 10 can move forward and backward while rotating, so that the winding mechanism 2 passes through the front and rear brush rollers when it descends. Figure 1 and Figure 2 As shown, a fixed plate 18 is provided at the end of the rear bracket 8, and a telescopic cylinder 19 is provided on the fixed plate 18. The output end of the telescopic cylinder 19 is connected to the rear end of the push plate 13. The telescopic cylinder 19 drives the push plate 13 and thus drives the movable brush roller 10 to move forward and backward. When the movable brush roller 10 moves to the front end, its bristles cross-contact with the bristles of the fixed brush roller 9. The bristles on the movable brush roller 1 and the fixed brush roller 9 can be arranged along the axis diameter as shown in the figure, or they can be arranged in the opposite direction of the rotation direction to facilitate brushing away dust and debris on the fire hose.

[0023] Before use, the automatic fire hose cleaning device has the mobile brush roller 10 in the rear position. The reeling mechanism 2 moves down along the frame 1, hanging the fire hose on the reeling mechanism 2. The reeling mechanism 2 then moves upward, driving the fire hose upward. The fire hose is in the suspended state. The telescopic cylinder pushes the push plate, driving the mobile brush roller forward, causing the brushes of the mobile brush roller to intersect with the brushes of the fixed brush roller, while clamping the lower end of the fire hose. Driven by motors 1 and 2, the brush rollers start to clean the fire hose. Simultaneously, the nozzles of the cleaning mechanism at the upper end of the brush rollers spray water on the fire hose, flushing away dust and debris. As the cleaning mechanism and brush roller mechanism operate, the reeling mechanism drives the fire hose downward, further cleaning the entire fire hose. After cleaning is complete, the mobile brush roller moves back, and the reeling mechanism drives the fire hose upward. During the upward movement, the cleaning mechanism can continue to spray water or stop. After the reeling mechanism reaches the top, the fire hose is hung to dry and then reeled up for next use.

[0024] The motor, telescopic cylinder, water pump and other devices involved in the embodiments of the present invention are all conventional equipment in the field, and any driving mechanism that can drive the brush roller in the embodiments of the present invention to rotate and the push plate to move back and forth can be used.

[0025] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
