Description
Technical Field
[0001] This utility model relates to the field of fire hose reel technology, specifically a fire hose reel with good sealing performance. Background Technology
[0002] Fire hose reels are convenient fire extinguishing devices fixed inside buildings. They are mainly used to extinguish initial fires involving solid combustibles. They are relatively simple to operate, can be quickly pulled out and used, and spray medium-pressure water to control the fire before it spreads. They are especially suitable for emergency self-rescue by non-professionals.

It includes a mounting bracket and a winding reel assembly set at one end of the mounting bracket. A cleaning component is fixedly installed on the outer wall of the protruding round block. When the operator winds up the water pipe, the semi-circular opening clamp is wrapped around the outer surface of the protruding round block. According to the winding position of the water pipe, the threaded short post at one end of the arc-shaped long rod is screwed into the corresponding mounting screw groove of the semi-circular opening clamp. The arc-shaped long rod drives the plastic round block to be set on one side of the reel assembly. One end of the water pipe passes through the through groove cavity on one side of the plastic round block. When the water pipe is wound up, the cotton layer wipes the dirt on the outer surface of the water pipe, improving the hygiene of the water pipe during winding. At the same time, the operator can disassemble the arc-shaped long rod and the plastic round block by disassembling the threaded short post and the mounting screw groove, and replace the dirty plastic round block.

Detailed Implementation
[0018] 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.
[0019] Please see Figure 1 This embodiment of a fire hose reel with good sealing performance includes a mounting plate 1. Multiple support rods 2 are fixed on the right side of the mounting plate 1. The multiple support rods 2 can support a stabilizing plate 3 and ensure that the stabilizing plate 3 does not rotate, thereby indirectly supporting a rotating shaft 4. The stabilizing plate 3 is fixed on the side of the multiple support rods 2 away from the mounting plate 1. The rotating shaft 4 is rotatably connected to the right side of the mounting plate 1 and located inside the multiple support rods 2 via a bearing. The bearing can provide stable support force for the rotating shaft 4. A fire hose 5 is fixedly connected to the outer surface of the rotating shaft 4. The fire hose 5 is wound around the outer surface of the rotating shaft 4. The rotating shaft 4 passes through the stabilizing plate 3. A water injection component 7 is provided on the right side of the rotating shaft 4 to supply water to the fire hose 5. A winding mechanism 6 is provided on the right side of the stabilizing plate 3 to realize the automatic winding and unwinding of the fire hose 5.
[0020] It is known that a large bearing is fixed on the outer surface of the rotating shaft 4. The large bearing can prevent the rotation of the rotating shaft 4 from affecting the stabilizing plate 3. The rotating shaft 4 is rotatably connected to the stabilizing plate 3 through the large bearing. A water passage hole is opened on the right side of the rotating shaft 4. The water passage hole can transmit water into the fire pipe 5. The fire pipe 5 is connected to the water passage hole. An ear plate is fixed on the outer surface of the mounting plate 1. Multiple mounting bolts are provided on the ear plate. Through the cooperation of the ear plate and the mounting bolts, the fire hose reel can be smoothly fixed to a stable structure such as a wall, providing good and stable operating conditions for the fire hose reel.
[0021] In addition, a mounting slot is provided on the right side of the stabilizing plate 3. The winding mechanism 6 includes a drive motor 601 fixed to the inner wall of the mounting slot. The mounting slot serves to provide space. Since the distance between the water injection component 7 and the stabilizing plate 3 is limited, the mounting slot needs to provide additional space for the drive motor 601 in order to ensure the smooth operation of the winding mechanism 6. One end of the output shaft of the drive motor 601 is fixed with a drive rod 602. A drive gear 603 is fixed on the outer surface of the drive rod 602. A driven gear 604 is fixed on the outer surface of the rotating shaft 4. The drive gear 603 meshes with the driven gear 604. The pitch circle diameter of the drive gear 603 is smaller than that of the driven gear 604. This reduces the rotational speed and increases the output torque when the drive gear 603 and the driven gear 604 mesh.
[0022] In this embodiment, the winding mechanism 6 helps the rotating shaft 4 to rotate, thereby realizing the release and winding of the fire pipe 5. After the fire is extinguished, the fire pipe 5 can be easily retracted, reducing the burden of using the device.
[0023] Please see Figures 2 to 3 To improve sealing, the water injection assembly 7 in this embodiment includes a water injection pipe 701 extending into and communicating with the rotating shaft 4. A water pump is fixedly connected to one end of the water injection pipe 701 away from the rotating shaft 4, and a fire-fighting device, such as a fire hydrant, is fixedly connected to the other end of the water pump away from the water injection pipe 701. A threaded pipe 702 is fixedly attached to the outer surface of the water injection pipe 701 and located outside the rotating shaft 4. A support portion 703 is provided on the outer side of the threaded pipe 702, and a sealing portion 704 is provided on the support portion 703. Through the cooperation of the support portion 703 and the sealing portion 704, both the stability of the connection between the fire-fighting pipe 5 and the rotating shaft 4 and the sealing performance at the connection point can be improved.
[0024] Furthermore, the support part 703 includes a threaded cylinder 7031, and multiple side plates 7032 are fixed on the outer surface of the threaded cylinder 7031. The side plates 7032 and the support rods 7033 cooperate to provide the necessary support force for the threaded cylinder 7031. The support rods 7033 are fixed on the left side of each of the multiple side plates 7032. The inner side of the threaded cylinder 7031 is threadedly connected to the threaded pipe 702. The threaded connection between the threaded cylinder 7031 and the threaded pipe 702 can improve the stability of the water injection pipe 701.
[0025] In addition, the sealing part 704 includes a sealing strip 7041 fixed to the right side of the rotating shaft 4. The sealing strip 7041, the conical ring 7042, and the conical groove all serve to obstruct water flow. The conical ring 7042 is fixed to the right side of the rotating shaft 4. A conical groove is opened on the left side of the water injection pipe 701. The conical ring 7042 extends into the conical groove. A waterproof pipe 7043 is fixed to the left side of the threaded cylinder 7031. The water injection pipe 701 is located inside the waterproof pipe 7043.
[0026] It is known that the active rod 602 is rotatably connected to the side plate 7032 through a bearing, and a sealed bearing is fixed on the inner side of the rotating shaft 4. The outer surface of the water injection pipe 701 abuts against the inner ring of the sealed bearing, and the sealed bearing plays a sealing role. In addition, a soft rubber strip is fixed on the left side of the waterproof pipe 7043. The soft rubber strip and the waterproof pipe 7043 play a second sealing role.
[0027] In this embodiment, the sealing bearing, soft rubber strip, and waterproof pipe 7043 work together to achieve a double sealing effect. Furthermore, the sealing strip 7041, conical ring 7042, and conical groove work together to impede the water flow, thereby effectively blocking the water and achieving a good sealing effect.
[0028] Understandably, the winding mechanism 6 can control the rotation of the rotating shaft 4, thereby enabling the release and winding of the fire hose 5. The water injection component 7 can improve the sealing between the water injection pipe 701 and the rotating shaft 4, reducing the waste of water resources.
[0029] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0030] The working principle of the above embodiments is as follows: When needed, first align the water injection pipe 701 with the rotating shaft 4, then rotate the water injection pipe 701 to cause the threaded pipe 702 to connect with the threaded cylinder 7031 until the waterproof pipe 7043 abuts against the side wall of the driven gear 604. At this time, the water injection pipe 701 also smoothly passes through the sealed bearing. Then start the drive motor 601, which drives the drive gear 603 to rotate, thereby causing the rotating shaft 4 inside the driven gear 604 to rotate, releasing the fire pipe 5 wrapped around the outer surface of the rotating shaft 4. When the fire pipe 5 moves to the fire position, water is injected into the rotating shaft 4 through the water injection pipe 701 to ensure that water flows into the fire pipe 5 to extinguish the fire.
