[0054] See Figures 1-6 , a water squeezing device for a fire hose reel, including: a driving mechanism, a water squeezing mechanism, and a pressing mechanism.

[0055] A rotating shaft 1 is connected to the output end of the driving mechanism. The driving mechanism is used to drive the rotation of the rotating shaft 1 to wind the fire hose. A first limiting plate 2 and a second limiting plate 3 are connected to the rotating shaft 1. During winding, the fire hose is located between the first limiting plate 2 and the second limiting plate 3. By means of the first limiting plate 2 and the second limiting plate 3, the wound fire hose can be limited during the rotation of the rotating shaft 1 to prevent deviation during the winding process.

[0056] During the winding process, the water in the fire hose can be squeezed out by the water squeezing mechanism while winding, preventing water accumulation inside the wound fire hose, which is convenient for storage, picking up, placing and transportation. In addition, in order to make the wound fire hose more flat during the winding process, a pressing mechanism is also provided. One end of the pressing mechanism is in contact with the fire hose during the rotation and winding of the rotating shaft 1, making the rotating and winding fire hose more flat and tight.

[0057] Further, the driving mechanism includes: two support frames 4. A driving motor 5 is fixedly connected to one of the support frames 4. The driving motor 5 can be a reduction motor. The output end of the driving motor 5 passes through the support frame 4 and is fixedly connected to one end of the rotating shaft 1. The output end of the driving motor 5 is rotatably connected to the support frame 4 through a bearing. The other support frame 4 can be rotatably connected to the rotating shaft 1 through a bearing. The fire hose can be wound by driving the rotating shaft 1 by the driving motor 5.

[0058] Further, the first limiting plate 2 is fixedly connected to the end of the rotating shaft 1 close to the driving mechanism. A section of thread is provided at the end of the rotating shaft 1 far from the driving mechanism. The second limiting plate 3 is threadedly connected to the end of the rotating shaft 1 far from the driving mechanism. The first limiting plate 2 and the second limiting plate 3 can be circular plates, which are used for limiting during the winding process, and the second limiting plate 3 can be removed after the winding is completed, facilitating the extraction of the wound fire hose from the rotating shaft 1.

[0059] Further, the water squeezing mechanism includes: two U-shaped brackets 6. The heights of the two U-shaped brackets 6 are lower than those of the first limiting plate 2 and the second limiting plate 3. Strip-shaped holes 9 are provided on the top support rods of the two U-shaped brackets 6. One inner wall of the strip-shaped hole 9 is fixedly connected to one end of the telescopic rod 10. A spring 12 is sleeved on the telescopic rod 10, and the other end of the telescopic rod 10 is fixedly connected to a connecting block 11. A second rotating roller 8 is rotatably connected between the two connecting blocks 11. A first rotating roller 7 is also rotatably connected between the top support rods of the two U-shaped brackets 6. The first rotating roller 7 and the second rotating roller 8 are at the same height.

[0060] In the initial state, the spring 12 is in a semi-compressed state. The spring 12 pushes the connecting block 11, thereby pushing the second rotating roller 8 in the direction of the first rotating roller 7, so that the second rotating roller 8 is in close contact with the first rotating roller 7. When in use, the spring 12 is compressed, the middle position after folding the fire hose is first passed through between the first rotating roller 7 and the second rotating roller 8, and wound around the rotating shaft 1. Then the spring 12 is released, and the fire hose is clamped between the first rotating roller 7 and the second rotating roller 8. The driving motor 5 is started to begin winding. During the winding process of the fire hose, the fire hose passes between the second rotating roller 8 and the first rotating roller 7 to filter the remaining water.

[0061] Further, connecting plates 13 are connected to the side walls of the connecting block 11 away from the second rotating roller 8. The connecting plates 13 are located outside the U-shaped bracket 6, and a pulling handle 14 is connected to the connecting plates 13. The pulling handle 14 is of a U-shaped structure and is connected to the two connecting plates 13 at both ends respectively. The connecting block 11 can be pulled to compress the spring 12 through the pulling handle 14, which is more convenient when the fire hose passes between the first rotating roller 7 and the second rotating roller 8.

[0062] Further, the pressing mechanism and the water squeezing mechanism are respectively located on opposite sides of the rotating shaft 1. The pressing mechanism includes: a support plate 15 and an electric push rod 16. The support plate 15 is located below the middle position between the two U-shaped brackets 6. The bottom of the electric push rod 16 is hinged to the top of the support plate 15. Connecting rods 19 are fixedly connected to the top struts of the two U-shaped brackets 6. A connecting shaft 17 is fixedly connected between the two connecting rods 19. A pressing plate 18 is rotatably connected to the connecting shaft 17. One end of the pressing plate 18 is hinged to the output end of the electric push rod 16, and the other end of the pressing plate 18 is located directly above the rotating shaft 1, and the end of the pressing plate 18 located directly above the rotating shaft 1 is of an arc-shaped structure.

[0063] During specific use, first, make the output end of the electric push rod 16 contract, pull the pressing plate 18 to rotate on the connecting shaft 17, so that the pressing plate 18 moves away from the rotating shaft 1. First, pass the middle position of the folded fire hose through between the first rotating roller 7 and the second rotating roller 8, and wind it around the rotating shaft 1. Then, extend the output end of the electric push rod 16 to push the pressing plate 18 to rotate towards the rotating shaft 1, so that the pressing plate 18 contacts the fire hose. Then, start the driving motor 5 to start winding. During the winding process of the fire hose, the water squeezing mechanism squeezes water, and the pressing plate 18 presses and smooths the fire hose to prevent wrinkles. As the diameter of the fire hose increases, the electric push rod 16 slowly contracts, driving the pressing plate 18 to gradually lift until both ends of the fire hose are wound to the positions of the first rotating roller 7 and the second rotating roller 8. Pull the connecting block 11 by pulling the handle 14 to compress the spring 12, and take out both ends of the fire hose from between the first rotating roller 7 and the second rotating roller 8. Remove the second limiting plate 3, and pull out the wound fire hose from the rotating shaft 1 to complete the winding of the fire hose.

[0064] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
