Abstract
Description
Technical Field
[0001] This utility model relates to the field of water spraying technology, specifically a water spray head with adjustable spraying area. Background Technology
[0002] Firefighting equipment generally refers to firefighting tools, which are used for fire extinguishing, fire prevention, and fire accidents. They are specialized firefighting equipment. A fire sprinkler head is a sprinkler head with a heat-sensitive element as a glass bulb. When the sprinkler head is heated, the working fluid inside the glass bulb reacts, causing the bulb to burst and open, thus providing timely and effective fire prevention.
[0003] However, this type of pipeline irrigation equipment mainly consists of pipelines, several water pipes, and nozzles. It has a simple structure and a limited watering area. Once it starts working, all nozzles will spray water, and it is impossible to control the nozzles to spray water on a specific area. This means that the number of nozzles needs to be increased to complete the watering work, which wastes raw materials. Utility Model Content
[0004] The purpose of this invention is to provide a sprinkler head with adjustable sprinkling area to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sprinkler head with adjustable sprinkling area, comprising a turntable, the upper end face of which is fixedly connected to a mounting frame, a first arc-shaped slide rail rotatably connected to the side wall of the mounting frame, one end of the first arc-shaped slide rail passing through the side wall of the mounting frame and fixedly connected to a second servo motor, a fixing plate fixedly connected inside the mounting frame, a second arc-shaped slide rail rotatably connected between the fixing plate and the mounting frame, an upper toothed plate fixedly connected to the bottom end of the second arc-shaped slide rail passing through the upper end face of the fixing plate, a coupling fixedly installed inside the mounting frame, a sliding rod fixedly connected to one side of the coupling, the surface of the sliding rod simultaneously slidingly connected to the inner walls of the first arc-shaped slide rail and the second arc-shaped slide rail, and a sprinkler head fixedly connected to one end of the sliding rod.
[0006] Preferably, a cover plate is slidably connected to the lower end face of the turntable, and a waterproof box is threadedly connected to the lower end face of the cover plate. A first servo motor is fixedly connected inside the waterproof box.
[0007] Preferably, the output end of the first servo motor is fixedly connected to a three-stage telescopic rod, the surface of the three-stage telescopic rod is fixedly connected to an internal gear, and the telescopic end of the three-stage telescopic rod is fixedly connected to a lower toothed plate.
[0008] Preferably, an external gear is provided at the center of the turntable, and the inner surface of the external gear meshes with the outer surface of the internal gear.
[0009] Preferably, the upper end face of the lower toothed plate is meshed with the lower end face of the upper toothed plate, and the three-stage telescopic rod is slidably connected inside the external gear.
[0010] Preferably, a water tank is threadedly connected to the lower end face of the cover plate, and a water pump is fixedly connected inside the water tank.
[0011] Preferably, the lower end face of the nozzle has a threaded hole, and a telescopic hose is threaded into the threaded hole, with one end of the telescopic hose threaded to the surface of the water tank.
[0012] Preferably, the water tank is fixedly connected to a connecting pipe at its water supply end, one end of which is fixedly connected to the surface of the water tank, and the water tank is connected to the telescopic flexible hose.
[0013] Compared with existing technologies, this utility model, by setting up a three-stage telescopic rod, first engages the internal gear and the external gear. Then, according to the required water spraying range, the first servo motor is activated to drive the turntable to rotate. Next, the three-stage telescopic rod is activated again, causing the upper toothed plate to engage with the lower toothed plate and the internal toothed plate to disengage from the external toothed plate. This allows one end of the first arc-shaped slide rail to move under the drive of the first servo motor. At the same time, the second servo motor is activated to drive the movement of the second arc-shaped slide rail. The movement of the first and second arc-shaped slide rails simultaneously drives the nozzle to move at multiple angles, which can control the nozzle to spray water on a specific area, reducing the number of nozzles required to a certain extent, and thus has high practicality.

The upper end of the turntable 1 is fixedly connected to a mounting frame 2. A first arc-shaped slide rail 10 is rotatably connected to the side wall of the mounting frame 2. One end of the first arc-shaped slide rail 10 passes through the side wall of the mounting frame 2 and is fixedly connected to a second servo motor 9. A fixing plate 13 is fixedly connected inside the mounting frame 2. A second arc-shaped slide rail 11 is rotatably connected between the fixing plate 13 and the mounting frame 2. The bottom end of the second arc-shaped slide rail 11 passes through the upper end of the fixing plate 13 and is fixedly connected to an upper toothed plate. A coupling 12 is fixedly installed inside the mounting frame 2. A sliding rod is fixedly connected to one side of the coupling 12. The surface of the sliding rod is simultaneously slidably connected to the inner walls of the first arc-shaped slide rail 10 and the second arc-shaped slide rail 11. One end of the sliding rod is fixedly connected to a nozzle 14.
[0022] The working principle of an adjustable sprinkler head based on Embodiment 1 is as follows: by setting the upper toothed plate and the lower toothed plate 7 to mesh, and the inner toothed plate 6 to disengage from the outer toothed plate 8, one end of the first arc-shaped slide rail 10 moves under the drive of the first servo motor 4. At the same time, the second servo motor 9 is started, driving the second arc-shaped slide rail 11 to move. Simultaneously, the movement of the first arc-shaped slide rail 10 and the second arc-shaped slide rail 11 drives the sprinkler head 14 to move at multiple angles. It can control the sprinkler head 14 to spray water on a certain area, reducing the number of sprinkler heads 14 used to a certain extent, and has high practicality.

The upper end face of the lower toothed plate 7 is meshed with the lower end face of the upper toothed plate. The three-stage telescopic rod 5 is slidably connected in the external gear 8. The lower end face of the cover plate is threadedly connected to a water tank 18. A water pump 17 is fixedly connected inside the water tank 18. A threaded hole is opened on the lower end face of the nozzle 14. A telescopic hose 15 is threadedly connected inside the threaded hole. One end of the telescopic hose 15 is threadedly connected to the surface of the water tank 18. A connecting pipe 16 is fixedly connected to the water supply end of the water tank 18. One end of the connecting pipe 16 is fixedly connected to the surface of the water tank 18. The water tank 18 and the telescopic hose 15 are connected.
[0025] In this embodiment, as Figure 2 As shown, by setting up a three-stage telescopic rod 5, the internal gear 6 and the external gear 8 are first engaged. Then, according to the water spraying range requirements, the first servo motor 4 is started to drive the turntable 1 to rotate. Next, the three-stage telescopic rod 5 is started again, which drives the upper toothed plate and the lower toothed plate 7 to engage, and the internal toothed plate 6 and the external toothed plate 8 to disengage. At the same time, the first servo motor 4 and the second servo motor 9 are started to drive the first arc-shaped slide rail 10 and the second arc-shaped slide rail 11 to move, and at the same time drive the nozzle 14 to move at multiple angles.
