Description

Technical Field

[0001] This utility model relates to the field of fire-fighting water distribution, and in particular to a fire-fighting water distribution device. Background Technology

[0002] With the continuous increase in high-rise buildings, fire safety hazards are also increasing. Fire water distributors are frequently used in fire safety. Fire water distributors are fire-fighting devices that connect the main fire water supply line with multiple branch water outlets.

[0003] The fire-fighting water distributor with three outlets disclosed in Chinese patent CN104132211A includes a main connector connected to a fire pump. One end of the main connector is provided with three parallel water distribution connectors. The angle between the first water distribution connector in the middle and the second and third water distribution connectors on both sides is 30 to 90 degrees. Each water distribution connector has a lever mounting position on its peripheral wall for mounting a lever. The lever is used to connect to a ball valve located in the water distribution connector to control the opening and closing of the water distribution connector.

[0004] The existing fire-fighting water distributors described above use three parallel water distribution connectors at one end of the main connector. The first water distribution connector in the middle and the second and third water distribution connectors on both sides have an angle of 30 to 90 degrees, which abandons the straight-line structure of the water outlet connector in the traditional technology and meets the normal fire-fighting needs of multiple water hoses working at the same time. However, in actual use, after the fire hose is connected to the water distribution connector, the end away from the interface is pulled to the fire-fighting position. During the process of pulling the hose, the hose is prone to excessive bending at the water distribution interface, which reduces the water output and reduces the fire-fighting efficiency.

[0005] To address the aforementioned problems, this utility model proposes a fire-fighting water distribution device. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a fire-fighting water distribution device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fire-fighting water distribution device, including a water storage pipe, with a first water distribution pipe, a second water distribution pipe and a third water distribution pipe evenly fixedly installed on the upper end face of the water storage pipe around the axis of the water storage pipe, the heights of the first water distribution pipe, the second water distribution pipe and the third water distribution pipe decreasing sequentially, and a water distribution elbow is rotatably and sealed at the top of the first water distribution pipe, the second water distribution pipe and the third water distribution pipe, and a filter plate is limited and installed in the outlet of the water distribution elbow.

[0008] The present invention is further configured such that a sealing pipe is fixedly sleeved on the outer side of the top of the first water distribution pipe, the second water distribution pipe and the third water distribution pipe, and a sealing ring is fixedly connected to the outer side of the bottom of the water distribution elbow. A sealing groove is opened on the inner wall of the sealing pipe, and the sealing ring is installed inside the sealing groove for sealing and rotation.

[0009] The present invention is further configured such that a connecting ring is fixedly connected to the bottom end of each of the water distribution elbows, and an annular groove is opened on the upper end face of the first water distribution pipe, the second water distribution pipe and the third water distribution pipe, and the connecting ring is sealed and rotatably installed inside the annular groove.

[0010] The present invention is further configured such that the bottom ends of the first water distribution pipe, the second water distribution pipe and the third water distribution pipe are all fixedly connected with water distribution ball valves.

[0011] The present invention is further configured such that limit holes are provided on both the upper and lower sides of the filter plate, and limit rods are slidably installed on the outer side of the water distribution elbow at the position corresponding to the limit holes. The end of the limit rod near the limit hole is set with an inclined surface, and the limit rod is inserted into the limit hole.

[0012] The present invention is further configured such that a pull plate is fixedly connected to the end of the limiting rod away from the limiting hole, and a spring is sleeved on the outer side of the limiting rod. One end of the spring is fixedly connected to the outer wall of the water-dividing elbow, and the other end of the spring is fixedly connected to the pull plate.

[0014] Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This fire-fighting water distribution device includes water distribution elbows, filter plates, sealing pipes, sealing rings, sealing grooves, connecting rings, annular grooves, and water distribution ball valves. By setting multiple water distribution elbows on water distribution pipes at different heights, the connecting rings at the bottom of the water distribution elbows rotate within the annular grooves at the top of the corresponding water distribution pipes. The sealing rings and connecting rings improve the sealing between the water distribution elbows and the water distribution pipes, allowing the water distribution elbows to rotate with the fire hoses and preventing excessive bending of the fire hoses from reducing the water output.

[0017] 2. This fire-fighting water distribution device, by incorporating a filter plate, limit rod, pull plate, and spring, can quickly clean the inside of the water distribution bend, reducing the accumulation of impurities inside the water distributor and extending its service life.

Detailed Implementation

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction. Similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right directions shown in the accompanying drawings. "Inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a fire-fighting water distribution device, including a water storage pipe 1, and a first water distribution pipe 2, a second water distribution pipe 3 and a third water distribution pipe 4 are uniformly fixedly installed on the upper end face of the water storage pipe 1 around the axis of the water storage pipe 1.

[0029] The top ends of the first water distribution pipe 2, the second water distribution pipe 3, and the third water distribution pipe 4 are all equipped with water distribution elbows 5 for sealing and rotatability. Specifically, a sealing pipe 7 is fixedly sleeved on the outer side of the top end of each of the three water distribution pipes. A sealing ring 8 is fixedly connected to the outer side of the bottom end of the water distribution elbow 5. A sealing groove 9 is opened on the inner wall of each sealing pipe 7, and the sealing ring 8 is rotatably installed inside the sealing groove 9. A connecting ring 10 is fixedly connected to the bottom end of each water distribution elbow 5. An annular groove 11 is opened on the upper end face of each of the three water distribution pipes, and the connecting ring 10 is rotatably installed inside the annular groove 11 for sealing and rotatability.

[0030] It should be noted that the heights of the first water distribution pipe 2, the second water distribution pipe 3, and the third water distribution pipe 4 decrease sequentially, so that the three water distribution elbows 5 will not interfere with each other when rotating.

[0031] Each water outlet of the water distribution elbow 5 is fitted with a filter plate 6. Specifically, the filter plate 6 has limit holes 13 on both the upper and lower sides. A limit rod 14 is slidably installed on the outer side of the water distribution elbow 5 at the position corresponding to the limit hole 13. The end of the limit rod 14 near the limit hole 13 is beveled, and the limit rod 14 is inserted into the limit hole 13. A pull plate 15 is fixedly connected to the end of the limit rod 14 away from the limit hole 13. A spring 16 is sleeved on the outer side of each limit rod 14. One end of the spring 16 is fixedly connected to the outer wall of the water distribution elbow 5, and the other end of the spring 16 is fixedly connected to the pull plate 15. After cleaning, the filter plate 6 is reinstalled into the water divider 5. The filter plate 6 cooperates with the inclined surface at the bottom of the limiting rod 14, pushing the limiting rod 14 away from the filter plate 6 and causing the spring 16 to extend. When the limiting hole 13 moves to below the limiting rod 14, the spring 16 contracts and drives the limiting rod 14 into the limiting hole 13, thereby limiting the filter plate 6.

[0032] In this embodiment of the invention, the bottom ends of the first water distribution pipe 2, the second water distribution pipe 3, and the third water distribution pipe 4 are all fixedly connected to water distribution ball valves 12. By controlling the corresponding water distribution ball valves 12, the first water distribution pipe 2, the second water distribution pipe 3, and the third water distribution pipe 4 can be controlled separately, improving the flexibility of the device.

[0033] A water inlet pipe 17 is fixedly connected to the lower end face of the water storage pipe 1, and a water inlet valve 18 is installed on the water inlet pipe 17.

[0034] Working principle:

[0035] When in use, connect the fire hose to the water distribution elbow 5. By opening the inlet valve 18, the water source enters the water storage pipe 1 from the inlet pipe 17. Open the water distribution ball valve 12, and the water source enters the water distribution elbow 5 through the corresponding water distribution pipe and is discharged into the fire hose.

[0036] When the fire hose is pulled, the hose causes the water distribution elbow 5 to rotate. The sealing ring 8 at the bottom of the water distribution elbow 5 rotates inside the sealing groove 9, and the connecting ring 10 at the bottom of the water distribution elbow 5 rotates inside the annular groove 11 at the top of the corresponding water distribution pipe. By setting the sealing ring 8 and the connecting ring 10, the sealing performance between the water distribution elbow 5 and the water distribution pipe is improved. This ensures that the water distribution elbow 5 rotates with the fire hose, preventing excessive bending of the fire hose from reducing the water output.

[0037] When the filter plate 6 blocks a lot of impurities and needs to be cleaned, pull the pull plate 15 to drive the limit rod 14 out of the limit hole 13, thereby releasing the limit on the filter plate 6. Remove the filter plate 6 to clean the impurities inside the water divider 5. After cleaning, reinstall the filter plate 6 into the water divider 5. The filter plate 6 cooperates with the inclined surface at the bottom of the limit rod 14, pushing the limit rod 14 away from the filter plate 6 and causing the spring 16 to extend. When the limit hole 13 moves to below the limit rod 14, the spring 16 retracts and drives the limit rod 14 into the limit hole 13, thereby completing the limit on the filter plate 6.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
