The inner wall of the assembly sleeve 34 is fixedly connected to a servo motor 35. The servo motor 35 is fixedly connected to the servo motor 36. The driving end of 5 is fixedly connected to the reel 36, and the surface of the reel 36 is provided with a reeling rope 37. By setting the lifting device 3, when maintenance is needed, the servo motor 35 is started, the reel 36 pays out the line, and the moving rod 33 drives the sprinkler pipe 1 to a predetermined position under the action of gravity, which is convenient for maintenance. After the maintenance is completed, the servo motor 35 rotates the reeling rope 37 in the opposite direction to reset the sprinkler pipe 1, which improves the convenience of maintenance of the sprinkler pipe 1, reduces maintenance cost and time, and also enhances the reliability and safety of the fire protection system.

[0022] Specifically, the side of the winding rope 37 away from the reel 36 is fixedly connected to the base plate 31, and the reel 36 is arranged on the lower surface of the base plate 31. By setting the winding rope 37, when the spray pipe 1 needs to be maintained, the servo motor 35 drives the reel 36 to rotate and loosen the winding rope 37 to pay out the line, so that the moving rod 33 is freed from the restraint and drives the spray pipe 1 to move downward. After reaching the predetermined position, it is convenient for maintenance.

[0023] Specifically, there are two slide bars 32, arranged in mirror-symmetrical configuration. These guide the upward and downward movement of the movable rod 33, ensuring smooth movement of the spray pipe 1 during its raising and lowering, without shaking or deflection. When maintenance is required on the spray pipe 1, the movable rod 33 smoothly moves downward to a predetermined position on the slide bars 32, controlled by gravity and the reel rope 37, for easy inspection.

[0024] Specifically, an adjustment component 4 is provided on the lower surface of the fixing ring 38, and the adjustment component 4 includes a connecting seat 44, which is fixedly connected to the fixing ring 38.

An arc-shaped tooth 41 is fixedly connected to the side of the spray pipe 1 close to the gear 42.

[0025] In this embodiment: by setting up the adjustment component 4, when the spray pipe 1 needs to be maintained, the servo motor 35, the reel 36 and the winding rope 37 cooperate to make the moving rod 33 drive the spray pipe 1 to move downward to a predetermined position for easy maintenance.

[0026] Specifically, the arc-shaped teeth 41 are meshed and connected with the gear 42 , and the arc-shaped teeth 41 are arranged in a semicircular shape.

[0027] In this embodiment, by providing a gear 42, when the fire alarm sprinkler 2 is triggered to spray water, the DC motor 43 drives the gear 42 to rotate, and the gear 42 cooperates with the arc-shaped teeth 41 to push the sprinkler pipe 1 to rotate, thereby adjusting the spraying angle.

[0028] Specifically, the gear 42 is disposed on the lower surface of the arc-shaped teeth 41 , and the spray pipe 1 is rotatably connected to the fixing ring 38 .

[0029] In this embodiment, by providing the arc-shaped teeth 41, when the fire alarm is triggered and the sprinkler head 2 sprays water, the DC motor 43 drives the gear 42 to rotate, and the arc-shaped teeth 41 cooperate with the gear 42 to push the sprinkler pipe 1 to rotate, thereby adjusting the spraying angle.

[0030] Working principle: By setting the lifting device 3 and the adjustment component 4, when the spray pipe 1 needs to be maintained, the servo motor 35 is started, and the servo motor 35 drives the reel 36 to rotate. While the reel 36 rotates, the reel rope 37 is loosened to release the line, and the moving rod 33 loses the restraint of the reel rope 37 and is affected by gravity to drive the spray pipe 1 to move downward. When it reaches the predetermined position, the servo motor 35 stops driving, and the spray pipe 1 can be repaired. When the maintenance is completed, the servo motor 35 is started to drive the reel 36 to rotate in the opposite direction and reel in the reel rope 37. At this time, the moving rod 33 is under force, and cooperates with the servo motor 35 to drive the spray pipe 1 to move upward. When the fire alarm is triggered and the sprinkler head 2 sprays water, the DC motor 43 drives the gear 42 to rotate. While the gear 42 rotates, it cooperates with the arc-shaped teeth 41 to push the sprinkler pipe 1 to rotate to adjust the spraying angle. By setting up the utility model, when maintenance is needed, the servo motor 35 is started, the reel 36 pays off the line, and the moving rod 33 drives the sprinkler pipe 1 to drop to a predetermined position under the action of gravity, which is convenient for maintenance. After the maintenance is completed, the servo motor 35 rotates the reel rope 37 in the opposite direction to reset the sprinkler pipe 1, thereby improving the convenience of maintenance of the sprinkler pipe 1, reducing maintenance costs and time, and also enhancing the reliability and safety of the fire protection system.
