Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problem of the inability to adjust the water outlet height of existing sprinkler heads, this invention provides a sprinkler device that allows for simultaneous rotation of the water spray assembly and adjustment of its height.

[0021] Please see Figure 1 and Figure 2 , Figure 1 and Figure 2 This is a schematic diagram of the structure of a water spraying device according to an embodiment of the present invention. The water spraying device includes a lifting assembly 1, a rotating assembly 2, and a spraying assembly 3. The lifting assembly 1 includes a frame 11, a sliding member 12, and a first driving member 13. The sliding member 12 is slidably connected to the frame 11, and the first driving member 13 is connected to the frame 11 and the sliding member 12, and is used to drive the sliding member 12 to rise and fall. The rotating assembly 2 includes a fixed pipe 21, a water outlet pipe 22, and a second driving member 23. The fixed pipe 21 is connected to the frame 11, and the water inlet end of the water outlet pipe 22 is rotatably connected to the fixed pipe 21. The second driving member 23 is connected to the fixed pipe 21 and the water outlet pipe 22, and is used to drive the water outlet pipe 22 to rotate. The water inlet end of the spraying assembly 3 is connected to the water outlet end of the water outlet pipe 22. The spraying assembly 3 can be a duckbill nozzle, a water spray nozzle, etc.

[0022] Specifically, when watering is required, water is introduced into the fixed pipe 21, and the water enters the water spraying assembly 3 through the fixed pipe 21 and is sprayed out from the water spraying assembly 3, which can water the road surface and vegetation.

[0023] When it is necessary to control the water spray height, the first drive component 13 is activated, which drives the sliding component 12 to slide. The sliding component 12 drives the fixed pipe 21, the water outlet pipe 22 and the water spray assembly 3 to rise and fall, thereby adjusting the water spray height of the water spray assembly 3. When it is necessary to spray water in different directions, the second drive component 23 is activated, which drives the water outlet pipe 22 to rotate relative to the fixed pipe 21. The water outlet pipe 22 drives the water spray assembly 3 to rotate, so that the water spray assembly 3 can spray water in different positions.

[0024] The sliding member 12 and the frame 11 can be slidably connected via a slide rail slider. Alternatively, the sliding member 12 can be slidably sleeved onto or slidably inserted into the frame 11 to achieve a slidable connection between the sliding member 12 and the frame 11. Specifically, for example... Figure 1 As shown, in one embodiment, the frame 11 includes a column 111; a slider 12 is slidably sleeved on the column 111. A first drive member 13 connects the column 111 and the slider 12. The frame 11 also includes a crossbeam 112, which is connected to the column 111 and is perpendicular to it.

[0025] In this embodiment, by sleeved the sliding member 12 on the column 111, the sliding connection between the sliding member 12 and the frame 11 is realized.

[0026] In order to limit the vertical sliding range of the slider 12, for this purpose, such as Figure 1 As shown, in one embodiment, the column 111 has a groove 11a along its length; the sliding member 12 includes a sliding sleeve 121 and a first limiting part 122. The sliding sleeve 121 is slidably sleeved on the column 111, and the first limiting part 122 is connected to the sliding sleeve 121 and at least partially slidably placed in the groove 11a. The first driving member 13 connects the sliding sleeve 121 and the column 111.

[0027] The sliding sleeve 121 is slidably sleeved on the column 111, realizing the sliding connection between the sliding sleeve 121 and the column 111. By opening a sliding groove 11a on the column 111 and inserting the first limiting part 122 into the sliding groove 11a, the first limiting part 122 can only slide within the sliding groove 11a, which can limit the vertical sliding range of the sliding sleeve 121.

[0028] In order to allow water to flow into the fixed pipe 21, for this purpose, as follows: Figure 1 As shown, in one embodiment, the sliding member 12 further includes a fixing plate 123, which is connected to the sliding sleeve 121; the rotating assembly 2 further includes a water inlet pipe 24, which is connected to the fixing plate 123, and the water outlet is connected to the fixing pipe 21.

[0029] By setting up the water inlet pipe 24, the water inlet pipe 24 connects the fixed pipe 21 with the fixed plate 123 and the sliding sleeve 121. When the sliding sleeve 121 rises and falls, the sliding sleeve 121 drives the fixed pipe 21 to rise and fall through the fixed plate 123 and the water inlet pipe 24. The water inlet pipe 24 is fixed relative to the fixed plate 123, and water is introduced into the water inlet pipe 24 and then enters the fixed pipe 21 through the water inlet pipe 24.

[0030] The sliding sleeve 121 and the fixed plate 123 can be connected by bolts, screws, and clips, specifically, as follows: Figure 1 As shown, in one embodiment, the slider 12 further includes a U-shaped bracket 124 and a nut 125. The U-shaped bracket 124 is sleeved on the slide sleeve 121 and its two ends pass through the fixing plate 123. The nut 125 is threaded to the end of the U-shaped bracket 124 and is disposed on the side of the fixing plate 123 away from the slide sleeve 121.

[0031] In this embodiment, when it is necessary to connect the fixing plate 123 and the sliding sleeve 121, the U-shaped bracket 124 is fitted onto the sliding sleeve 121, and both ends of the U-shaped bracket 124 are passed through the fixing plate 123. Then, the nut 125 is connected to the U-shaped bracket 124, and the fixing plate 123 is fixed to the sliding sleeve 121.

[0032] It should be understood that the second drive component 23 can be a direct drive motor, or a combination of a motor and a transmission mechanism, specifically, such as Figure 3 , Figure 6 and Figure 7 As shown, in one embodiment, the second driving member 23 includes a rotating part 231, a transmission part 232, and a driving part 233. The rotating part 231 is rotatably built into the fixed pipe 21 and connected to the water outlet pipe 22. A flow channel 231a communicating with the water outlet pipe 22 is formed inside the rotating part 231, and multiple water inlet windows 231b are opened on the peripheral wall of the rotating part 231. The transmission part 232 is connected to the rotating part 231, and the driving part 233 is connected to the fixed pipe 21 and the transmission part 232, and is used to drive the water spray assembly 3 to rotate via the transmission part 232 and the water outlet pipe 22. The rotating part 231 is a rotating body, and the transmission part 232 can be two pulleys, which are driven by a belt. One pulley is connected to the rotating part 231, and the other pulley is connected to the driving part 233. The transmission part 232 can also be two sprockets and a chain, or two meshing gears. The driving part 233 can be a motor or a hydraulic motor, etc.

[0033] When it is necessary to control the rotation of the water spray assembly 3, the drive unit 233 is activated. The drive unit 233 drives the rotating part 231 to rotate via the transmission unit 232. The rotating part 231 drives the water outlet pipe 22 and the water spray assembly 3 to rotate, thus realizing the rotation of the water spray assembly 3. Since water needs to enter the water outlet pipe 22 through the fixed pipe 21, in order to avoid the rotating part 231 from obstructing the water from entering the water outlet pipe 22, in this embodiment, a water flow channel 231a is formed inside the rotating part 231. Multiple water inlet windows 231b are opened on the peripheral wall of the rotating part 231. Water enters from the side wall of the fixed pipe 21, then enters the flow channel 231a through the water inlet window 231b, and then enters the water outlet pipe 22 through the flow channel 231a. During the rotation of the rotating part 231 inside the fixed pipe 21, the multiple water inlet windows 231b can always supply water to pass through, thus avoiding obstructing the water from entering the water outlet pipe 22.

[0034] In order to limit the axial movement of the rotating part 231, for this purpose, as follows: Figure 8 As shown, in one embodiment, the fixing tube 21 has a first fixing hole 21a, a second fixing hole 21b, and a third fixing hole 21c with successively decreasing inner diameters. A fixing ring 21d is formed in the third fixing hole 21c. The rotating part 231 is rotatably disposed in the first fixing hole 21a, the second fixing hole 21b, and the third fixing hole 21c. The second driving member 23 also includes a first bearing 234, which is sleeved on the rotating part 231 and its two ends abut against the rotating part 231 and the transmission part 232, respectively. The first bearing 234 can be a thrust ball bearing, a tapered roller bearing, etc.

[0035] In this embodiment, a fixed ring 21d is formed inside the fixed tube 21. The transmission part 232 abuts against the fixed ring 21d via the first bearing 234. The transmission part 232, the first bearing 234 and the rotating part 231 are supported by the fixed ring 21d, which can restrict the downward movement of the rotating part 231.

[0036] In order to limit the upward movement of the rotating part 231 along the axial direction, for this purpose, as follows: Figure 7 As shown, in one embodiment, the rotating part 231 is formed with a limiting protrusion 231c located in the first fixing hole 21a; the second driving member 23 further includes a second bearing 235, which is sleeved on both ends of the rotating part 231 and abuts against the end inner wall of the first fixing hole 21a and the limiting protrusion 231c respectively.

[0037] In this embodiment, by setting a limiting protrusion 231c, which abuts against the inner wall of the end of the first fixing hole 21a via the second bearing 235, the rotating part 231 can be restricted from moving upward along the axial direction.

[0038] The second bearing 235 can be a thrust ball bearing, a tapered roller bearing, or the like.

[0039] In order to seal the gap between the rotating part 231 and the inner wall of the fixed pipe 21, and to prevent water from leaking outward from the gap between the rotating part 231 and the fixed pipe 21, therefore, as follows: Figure 7 As shown, in one embodiment, a first sealing ring 236 is provided between the peripheral wall of the rotating part 231 and the inner wall of the first fixing hole 21a; a second sealing ring 237 is provided between the end of the rotating part 231 and the end inner wall of the second fixing hole 21b.

[0040] In this embodiment, by providing a first sealing ring 236 between the peripheral wall of the rotating part 231 and the inner wall of the first fixing hole 21a, the first sealing ring 236 can seal the bottom of the rotating part 231, preventing leakage from the bottom of the rotating part 231 downwards; by providing a second sealing ring 237 between the end of the rotating part 231 and the inner wall of the end of the second fixing hole 21b, the second sealing ring 237 can seal the top of the rotating part 231, preventing leakage from the top of the rotating part 231 outwards.

[0041] In order to limit the rotation angle of the rotating part 231, the water outlet pipe 22, and the water spray assembly 3, therefore, as follows: Figure 4 and Figure 5 As shown, in one embodiment, the rotating assembly 2 further includes a blocking member 25 and two limit switches 26 for rotational limiting. The blocking member 25 is connected to the rotating part 231, and the two limit switches 26 are both connected to the fixed tube 21 and are disposed on both sides of the fixed tube 21. The contacts of the limit switches 26 are disposed on the rotation path of the blocking member 25. The blocking member 25 can be an L-shaped block, rod, etc., fixed to the rotating part 231. The two limit switches 26 are electrically connected to the motor of the driving part 233 to form a closed-loop control, ensuring the accuracy and reliability of rotational limiting.

[0042] In this embodiment, by setting a blocking member 25, when the rotating part 231 rotates, it drives the blocking member 25 to rotate. When the blocking member 25 rotates to contact the contact of the limit switch 26, it will trigger the limit switch 26. The limit switch 26 controls the driving part 233 to stop rotating or rotate in the opposite direction. The cooperation of the two limit switches 26 can limit the rotation angle of the water spray assembly 3.

[0043] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
