Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire hose technology, specifically a fire hose with self-cleaning function. Background Technology
[0002] Fire hoses are an important piece of equipment used for fire fighting. They are mainly used to transport water or extinguishing agents from a water source to the fire scene and are a key component of the fire protection system.
[0003] For example, China provides a patent for "a fire hose with fireproof function" (patent number: 202322165851.9). This patent includes a hose body, with connecting rings symmetrically fixedly connected to the end faces of the hose body. The hose body has a base layer inside, and the outer wall of the base layer is fixedly connected with an anti-puncture layer. By setting multiple fireproof layers inside the fire hose, it can prevent external high temperatures from damaging the hose during fire fighting. At the same time, a metal anti-puncture layer is set inside the fire hose to prevent foreign objects from puncturing and damaging the fire hose during dragging, thereby improving its strength in use.
[0004] While the aforementioned document addresses the issue that existing fire hoses, typically wrapped in a layer of linen fabric, are susceptible to high-temperature damage from external heat or fire sources during firefighting, they still lack self-cleaning capabilities. When fire hoses enter and leave a fire scene, their surfaces accumulate significant amounts of dirt; rewinding them without cleaning increases the difficulty of rewinding and affects subsequent use. Therefore, this document introduces a fire hose with self-cleaning functionality. Utility Model Content
[0005] The purpose of this utility model is to provide a fire hose with a self-cleaning function, which has the advantage of self-cleaning.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire hose with self-cleaning function, comprising an outer shell, a winding shaft provided in the inner cavity of the outer shell, a fireproof hose sleeved on the surface of the winding shaft, an opening on one side of the outer shell, a hose connector passing through the inner cavity of the opening, a fixing shell fixedly connected to the top and bottom of one side of the outer shell, a spring fixedly connected to one side of the inner cavity of the fixing shell, a movable plate fixedly connected to one end of the spring, a telescopic frame fixedly connected to the side of the movable plate away from the spring, a clamping frame fixedly connected to one end of the telescopic frame, and a cleaning brush fixedly connected to one side of the inner cavity of the clamping frame.
[0007] As a preferred embodiment, a handle is fixedly connected to the top of the outer casing, and the surface of the handle is covered with an anti-slip sleeve.
[0008] As a preferred embodiment, threaded tubes are fixedly connected to the top and bottom of the inner cavity of the outer shell, and a screw is threadedly connected to the inner cavity of the threaded tube, with a clamping plate movably connected to one end of the screw.

[0020] 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.
[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0022] Example 1:
[0023] Please see Figures 1-4 As shown, this utility model provides a fire hose with a self-cleaning function, including an outer shell 1. The inner cavity of the outer shell 1 is provided with a winding shaft 2. A fireproof hose 3 is sleeved on the surface of the winding shaft 2. A through-hole 4 is opened on one side of the outer shell 1. A hose connector 5 is provided through the inner cavity of the through-hole 4. A fixing shell 6 is fixedly connected to the top and bottom of one side of the outer shell 1. A spring 7 is fixedly connected to one side of the inner cavity of the fixing shell 6. A movable plate 8 is fixedly connected to one end of the spring 7. A telescopic frame 9 is fixedly connected to the side of the movable plate 8 away from the spring 7. A clamping frame 10 is fixedly connected to one end of the telescopic frame 9. A cleaning brush 11 is fixedly connected to one side of the inner cavity of the clamping frame 10. When the fireproof hose 3 is wrapped around the winding shaft 2 and the winding shaft 2 is rotated, the fireproof hose 3 moves between the two cleaning brushes 11. As the fireproof hose 3 moves continuously, the cleaning brushes 11 can scrape off the dirt on the surface of the fireproof hose 3.
[0024] This technical solution incorporates a fixed housing 6, a spring 7, a movable plate 8, a telescopic frame 9, a clip frame 10, and a cleaning brush 11. A cleaning mechanism is installed on one side of the housing 1, which allows the fire hose to be cleaned to a certain extent when it is rewound after use, facilitating subsequent use.
[0025] Example 2:
[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-3As shown, a handle 12 is fixedly connected to the top of the outer shell 1, and an anti-slip sleeve is provided on the surface of the handle 12. Threaded tubes 13 are fixedly connected to the top and bottom of the inner cavity of the outer shell 1. A screw 14 is threadedly connected to the inner cavity of the threaded tube 13. A pressure plate 15 is movably connected to one end of the screw 14. Limiting grooves are provided on the top and bottom of one side of the outer shell 1. A limiting frame is movably connected to the inner cavity of the limiting groove. The end of the limiting frame away from the limiting groove is fixedly connected to the surface of the telescopic frame 9.
[0027] The above technical solution is mainly adopted to facilitate lifting of the outer shell 1, improve the winding tightness of the fire hose 3 and improve the moving stability of the telescopic frame 9. Holding the handle 12 by hand makes it easier and more convenient to lift the outer shell 1. Rotating the screw 14 causes the screw 14 to slowly move out as it rotates in the inner cavity of the threaded tube 13, and drives the pressure plate 15 to move to one side to press the surface of the fire hose 3. The limiting frame moves with the telescopic frame 9 in the inner cavity of the limiting groove, making the telescopic frame 9 more stable during movement and preventing it from shaking.
[0028] Example 3:
[0029] Based on Embodiment 2, this utility model is as follows: Figures 1-3 As shown, a drive frame 16 is fixedly connected to the side of the telescopic frame 9 away from the outer shell 1. An anti-slip pad is fixedly connected to the surface of the drive frame 16. A protective door 17 is fixedly connected to the front of the outer shell 1. A handle is fixedly connected to the front of the protective door 17.
[0030] The above technical solution is mainly used to facilitate the movement of the telescopic frame 9 and to protect the inner cavity of the outer shell 1. By stepping on the anti-slip mat and applying force, the lower telescopic frame 9 can be moved downward through the drive frame 16. Similarly, by holding the handle on one side of the upper telescopic frame 9 and applying force, the upper telescopic frame 9 can be moved upward, causing the two clip frames 10 to separate. The hose connector 5 can be inserted into the inner cavity of the outer shell 1. After the fireproof hose 3 is rolled up in the inner cavity of the outer shell 1, closing the protective door 17 can protect the inner cavity of the outer shell 1.
[0031] The working principle of this utility model is as follows: Open the protective door 17, pass the fireproof water hose 3 through the opening 4 and wrap it around the take-up shaft 2. The two telescopic frames 9 move closer to each other under the action of the spring 7, and the cleaning brush 11 in the inner cavity of the frame 10 at one end of the telescopic frame 9 is pressed against the surface of the water hose connector 5. Rotate the take-up shaft 2, and the fireproof water hose 3 will move between the two cleaning brushes 11. As the fireproof water hose 3 moves continuously, the cleaning brushes 11 can scrape off the dirt on the surface of the fireproof water hose 3.
