Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, specifically a water volume regulating device for fire protection. Background Technology

[0002] In firefighting operations, precise control of water volume is crucial for firefighting efficiency and rational resource utilization. Fire hoses, water cannons, and water collectors are key firefighting tools, and their water volume regulation function directly affects the effectiveness of firefighting.

[0003] Traditional fire hoses typically operate with a fixed water output, making it impossible to adjust flexibly according to the actual fire situation. When dealing with small fires, an excessive water output not only wastes a lot of water resources but may also cause unnecessary damage to the surrounding environment and materials. Conversely, when dealing with large fires, an insufficient water output makes it difficult to quickly and effectively suppress the fire, delaying the golden opportunity for firefighting and causing further fire damage.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing fire hoses. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Example 1: Please refer to Figure 1 - Figure 3This embodiment of a fire-fighting water volume regulating device includes a regulating pipe 1 and a water pipe 2. The two ends of the regulating pipe 1 are fixedly connected to the two water pipes 2. A handle 3 is provided at the top of the regulating pipe 1. A movable block 4 is fixedly connected to the bottom of the handle 3. A connecting block 5 is fixedly connected to the bottom of the movable block 4. Two racks 6 are fixedly connected to both ends of the connecting block 5. A gear 7 is meshed on one side of the rack 6. A valve 8 is fixedly connected to the bottom of the gear 7 through a rotating shaft. The valve 8 is rotatably connected inside the regulating pipe 1.

[0022] When it is necessary to adjust the water volume, move the handle 3. The handle 3 will drive the movable block 4 to move, the movable block 4 will drive the connecting block 5 to move, the connecting block 5 will drive the two racks 6 to move, the two racks 6 will drive the two gears 7 to rotate, and the two gears 7 will drive the two valves 8 to rotate through the rotating shaft, so that one end of the two valves 8 moves towards each other, thereby facilitating the adjustment of the water volume used for fire fighting. The operation is simple and convenient.

[0023] Furthermore, a rotating shaft 9 is fixedly connected to the bottom of the valve 8, and a groove 10 is machined on the inner wall of the bottom of the regulating pipe 1. The rotating shaft 9 is rotatably connected inside the groove 10. When the valve 8 is rotated, the rotating shaft 9 at the bottom of the valve 8 will rotate along the inside of the groove 10.

[0024] Furthermore, two rotating columns 13 are fixedly connected to the bottom ends of the valve 8, and two annular grooves 14 are machined on the bottom inner wall of the regulating pipe 1. The rotating columns 13 are movably connected inside the annular grooves 14. When the valve 8 rotates along the inside of the regulating pipe 1, the valve 8 will drive the two rotating columns 13 to rotate along the inside of the annular grooves 14, and the annular grooves 14 will limit the movement of the rotating columns 13.

[0025] Furthermore, a limit strip 11 is fixedly connected to one end of the valve 8, and a limit groove 12 is machined on the inner wall of one side of the regulating pipe 1. The limit strip 11 is snapped into the inside of the limit groove 12. When the two valves 8 are parallel, the limit strip 11 at one end of the valve 8 will snap into the inside of the limit groove 12, thereby limiting the valve 8 through the limit groove 12.

[0026] Furthermore, the top of the regulating tube 1 is machined with a movable groove 15, the rack 6 is movably connected inside the movable groove 15, a connecting groove 16 is machined on one side of the movable groove 15, and the movable block 4 is movably connected inside the connecting groove 16. When the movable block 4 moves, the movable block 4 will move along the inside of the connecting groove 16. By providing the movable groove 15, the movable groove 15 will limit the movement of the rack 6.

[0027] Furthermore, a ring 17 is provided at the top of the handle 3, and a limit pin 18 is fixedly connected to the bottom of the ring 17. Multiple limit holes 19 are machined at the top of the adjusting tube 1, and the limit pin 18 is plugged into the inside of the limit hole 19. When it is necessary to move the handle 3, first lift the ring 17 upward, and the ring 17 will drive the limit pin 18 to move upward. The limit pin 18 will disengage from the inside of the limit hole 19, thereby releasing the limit of the handle 3.

[0028] Furthermore, a return spring 20 is provided on the outside of the limiting pin 18. The top of the return spring 20 is fixedly connected to the bottom of the ring 17, and the bottom of the return spring 20 is fixedly connected to the top of the handle 3. With the return spring 20 provided, when the ring 17 is pulled, the ring 17 will drive the return spring 20 to stretch. When the ring 17 is released, the return spring 20 will return to its original position and retract. The return spring 20 will drive the limiting pin 18 to move, so that the limiting pin 18 can be inserted into the interior of the limiting hole 19.

[0029] Working principle: By moving the handle 3, the handle 3 will drive the movable block 4 to move, the movable block 4 will drive the connecting block 5 to move, the connecting block 5 will drive the two racks 6 to move, the two racks 6 will drive the two gears 7 to rotate, and the two gears 7 will drive the two valves 8 to rotate through the rotating shaft, so that one end of the two valves 8 moves towards each other, thereby facilitating the adjustment of the water volume used for fire fighting. The operation is simple and convenient.
