[0032] 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. Example

[0033] Please see Figures 1-5 The present invention provides the following technical solution: an adjustable nozzle device, including a fixed base 1 and a movable base 2 rotatably connected to the bottom of the fixed base 1;

[0034] The fixed base 1 is provided with a clearance hole 18, and the top of the movable base 2 is provided with a connecting rod 3, the top of the connecting rod 3 passing through the clearance hole 18;

[0035] The bottom of the movable base 2 is provided with mounting brackets 5 on both sides, and the two mounting brackets 5 are provided with rotating base 10, and the nozzle body 12 is provided on the rotating base 10.

[0036] A horizontal adjustment component is provided on the fixed base 1 and the connecting rod 3, which is used to drive the movable base 2 to rotate horizontally at the bottom of the fixed base 1;

[0037] Two sets of angle adjustment components are respectively mounted on two mounting brackets 5, used to drive the rotating seat 10 to adjust the angle on the two mounting brackets 5. In use, the horizontal adjustment component can drive the connecting rod 3 to drive the moving seat 2 to rotate horizontally around the central axis of the fixed seat 1, thereby adjusting the horizontal spray direction of the nozzle body 12. At the same time, the two sets of angle adjustment components can synchronously or independently drive the rotating seat 10 to adjust the pitch angle between the two mounting brackets 5, thereby changing the vertical spray angle of the nozzle body 12. When precise spraying of a specific area is required, the horizontal adjustment component can be operated first to roughly align the nozzle body 12 with the horizontal direction of the target area, and then the pitch angle can be finely adjusted by the angle adjustment component, so that the sprayed medium can accurately cover the target area, greatly improving the flexibility and accuracy of the spraying operation.

[0038] Preferably, by Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the horizontal adjustment assembly includes a second worm gear 13 fixed to the outer wall of the connecting rod 3, and the second worm gear 13 is located above the fixed base 1;

[0039] The top of the fixed base 1 is rotatably connected to the second worm gear 14, which meshes with the second worm wheel 13;

[0040] A second small motor 15 for driving the second worm gear 14 to rotate is also installed on the top of the fixed base 1. In use, the second small motor 15 is started, and the output shaft of the second small motor 15 drives the second worm gear 14 to rotate. Since the second worm gear 14 meshes with the second worm wheel 13 fixed on the outer wall of the connecting rod 3, the rotation of the second worm gear 14 will drive the second worm wheel 13 to rotate around its central axis, thereby driving the connecting rod 3 and the movable base 2 connected to the bottom of the connecting rod 3 to rotate horizontally around the central axis of the fixed base 1. By controlling the forward and reverse rotation and the rotation angle of the second small motor 15, the horizontal spray direction of the nozzle body 12 at the bottom of the movable base 2 can be precisely adjusted to meet the spraying needs of different horizontal positions. This worm gear transmission method has the characteristics of smooth transmission, precise transmission ratio and good self-locking. It can ensure that the nozzle body 12 is stably maintained after being adjusted to the required horizontal direction and will not be deviated due to external vibration or other factors, thus ensuring the reliability and accuracy of horizontal adjustment.

[0041] Preferably, by Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the angle adjustment assembly includes a connecting bracket 11 fixed to the top of the rotating seat 10;

[0042] The mounting bracket 5 is rotatably connected to the connecting column 6, and the connecting bracket 11 is fixed to the outer wall of the connecting column 6;

[0043] A first worm gear 7 is fixed to the outer wall of the connecting column 6, and a first worm 8 is rotatably connected inside the mounting bracket 5, with the first worm 8 meshing with the first worm gear 7.

[0044] A first small motor 9 for driving the first worm gear 8 to rotate is installed on one side of the mounting bracket 5. In use, the first small motor 9 is started, and the output shaft of the first small motor 9 drives the first worm gear 8 to rotate. Since the first worm gear 8 meshes with the first worm wheel 7 fixed on the outer wall of the connecting column 6, the rotation of the first worm gear 8 will drive the first worm wheel 7 to rotate around its central axis, thereby driving the connecting column 6 and the connecting bracket 11 and the rotating seat 10 connected to the connecting column 6 to rotate synchronously. When the first small motors 9 in the two sets of angle adjustment components start synchronously and have the same direction and speed, the rotating seat 10 will drive the nozzle body 12 to perform overall pitch angle adjustment, realizing the overall change of the spray height. Similarly, the transmission structure of the first worm gear 8 and the first worm wheel 7 also has the advantages of smooth transmission, accurate transmission ratio and good self-locking, so that the nozzle body 12 can be stably fixed after the vertical angle is adjusted, effectively avoiding angle deviation caused by spray reaction force or external interference, and significantly improving the stability and accuracy of angle adjustment.

[0045] Preferably, by Figure 1 , Figure 3 and Figure 5As shown, in this embodiment, a fixing plate 4 is fixed to the top of the connecting rod 3, and multiple fixing brackets 16 are provided circumferentially at the bottom of the fixing plate 4. Rollers 17 are rotatably connected to each fixing bracket 16. The outer wall of the rollers 17 abuts against the top of the fixing seat 1, and the height of the fixing bracket 16 is less than the height of the connecting rod 3. By setting the fixing plate 4, fixing brackets 16, and rollers 17, the rotation of the connecting rod 3 on the fixing seat 1 can be assisted and supported. When the connecting rod 3 rotates around the central axis of the fixing seat 1 under the drive of the horizontal adjustment component, the multiple rollers 17 at the bottom of the fixing plate 4 will roll along the top surface of the fixing seat 1, effectively dispersing the pressure of the connecting rod 3 and its connecting components on the fixing seat 1, and avoiding problems such as tilting and shaking of the connecting rod 3 due to long-term force or rotation. This ensures the smooth and stable horizontal rotation of the movable seat 2, thereby indirectly improving the accuracy and reliability of the horizontal adjustment of the nozzle body 12. At the same time, the height of the fixed frame 16 is less than the height of the connecting rod 3. When the outer wall of the roller 17 abuts against the top surface of the fixed seat 1, the movable seat 2 will move slightly down to the bottom of the fixed seat 1, avoiding the top of the movable seat 2 directly abutting against the bottom of the fixed seat 1 and generating frictional resistance. This ensures that the movable seat 2 can rotate flexibly horizontally. In addition, multiple rollers 17 are circumferentially distributed at the bottom of the fixed plate 4, which can support the connecting rod 3 from multiple directions, further enhancing the stability of the overall structure and preventing the connecting rod 3 from becoming eccentric or wobbling during rotation. This provides a solid structural foundation for the precise positioning of the nozzle body 12.

[0046] Preferably, by Figure 1 and Figure 5 As shown, in this embodiment, the diameter of the clearance hole 18 is larger than the diameter of the connecting rod 3; this design provides sufficient room for the rotation of the connecting rod 3, effectively preventing the connecting rod 3 from contacting and rubbing against the hole wall of the clearance hole 18 when rotating around the central axis of the fixed base 1.

[0047] Preferably, by Figure 3 As shown, in this embodiment, the roller 17 is made of nylon. Nylon not only has good wear resistance and self-lubrication, which can effectively reduce the coefficient of friction when the roller 17 rolls against the top surface of the fixed seat 1, reduce wear between parts, and extend service life, but also has a relatively light weight, which will not significantly increase the overall weight of the movable seat 2, and helps to maintain the flexibility of the movable seat 2 when rotating.

[0048] Components not described in detail in this article are existing technologies.

[0049] The working principle and usage process of this utility model are as follows: When in use, first, the fixing base 1 is securely installed at the preset installation point of the fire sprinkler system using the matching fasteners, and then the water inlet of the sprinkler body 12 is sealed and connected to the fire water supply hose to ensure that the water supply path is unobstructed and leak-free.

[0050] When spraying is required, first activate the leveling component: the second small motor 15 is powered on and rotates the second worm gear 14. Through the meshing transmission between the worm gear and the worm wheel, the second worm wheel 13, together with the connecting rod 3 and the moving seat 2, is driven to rotate smoothly and horizontally around the central axis of the fixed seat 1. During this process, the nylon roller 17 at the bottom of the fixed plate 4 rolls synchronously along the top surface of the fixed seat 1, distributing the load, eliminating frictional resistance, and preventing the connecting rod 3 from eccentrically wobbling, thus accurately adjusting the nozzle body 12 to the horizontal position of the target area. After the adjustment is in place, the second small motor 15 is turned off, and the worm gear self-locking structure immediately locks the horizontal angle, preventing horizontal deviation due to vibration or water flow impact.

[0051] Then, the angle adjustment component is activated: the first small motors 9 on both sides are activated simultaneously, driving the first worm gear 8 to rotate, which in turn engages the first worm wheel 7 to drive the connecting column 6, connecting frame 11 and rotating seat 10 to rotate synchronously in pitch, precisely adjusting the vertical spray angle of the nozzle body 12; if local fine-tuning of the deflection angle is required, the first small motor 9 on one side can be controlled separately to achieve differentiated adjustment; after the adjustment is completed, the first small motor 9 is turned off, and the pitch angle is locked by the self-locking characteristic of the worm gear, resisting the reaction force of high-pressure water spray and external interference, and preventing angle deviation;

[0052] After the orientation and angle are adjusted, the fire water supply system is turned on. The water flows through the nozzle body 12 and is accurately sprayed to the ignition point or target spraying area, with no spray dead corners and more efficient fire extinguishing coverage. After the operation is completed, the fire water supply is turned off, and the second small motor 15 is controlled to run in reverse with the first small motor 9 to reset the nozzle body 12 to the initial standby state, thus completing the entire operation process.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
