[0002] Gardens are not only used for recreation, but also have the function of protecting and improving the environment. Plants can absorb carbon dioxide, release oxygen, purify the air, absorb harmful gases and adsorb dust to a certain extent, and reduce pollution. In the daily maintenance of gardens, it is often necessary to water the flowers, plants and trees in the gardens to maintain their growth.

[0003] The method of watering directly with a water pipe is inefficient, labor-intensive, and wasteful of water resources. Therefore, sprinklers are currently commonly used to water garden plants. Common sprinkler systems typically have pipes buried beneath the ground, with vertical pipes installed at regular intervals. The vertical pipes protrude a certain height above the ground. A sprinkler head is installed at the top of the vertical pipe, and water is sprayed from the sprinkler head to irrigate the surrounding plants. However, this type of sprinkler system has the following disadvantages when used:

[0004] Since the vertical water pipes in the sprinkler device protrude above the ground and have a certain height, in some public places, such as gardens in parks, children may mischievously shake the vertical water pipes, causing damage to the pipes. It is also possible that when planting new plants, some mechanical equipment needs to be used, and during operation, the mechanical equipment may collide with the vertical pipes, causing damage to them.

DETAILED DESCRIPTION

[0026] The following is a non-limiting detailed description of the technical solution of the present invention in conjunction with preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0027] Example 1:

[0028] See also Figure 1 The utility model provides a technical solution: a sprinkler device that is easy to fix, including a tee 1 and a standpipe 2, one end of the tee 1 is fixedly connected to a pre-buried pipe 11, the top of the pre-buried pipe 11 is fixedly connected to a threaded barrel 12, the tee 1 is used to connect to the underground pipeline, the pre-buried pipe 11 is buried vertically upward in the soil, and the part of the threaded barrel 12 is exposed above the ground, and a sprinkler head 21 is fixedly installed on the top of the standpipe 2, and a thread is opened on the inner wall of the bottom end of the standpipe 2, and the thread of the inner wall of the bottom end of the standpipe 2 is threadedly connected to the outer surface of the threaded barrel 12. The standpipe 2 supports the sprinkler head 21 at a certain height, so that it can spray garden plants within a relatively far range.

[0029] Specifically, it also includes a sealing cap 5. The inner wall of the sealing cap 5 is provided with a thread that can be threadedly connected to the threaded barrel 12. After the vertical pipe 2 is disassembled, the sealing cap 5 can be threadedly connected to the surface of the threaded barrel 12, thereby preventing dust from entering the embedded pipe 11, causing the dust to be washed into the nozzle 21 by water during the next use, causing the nozzle 21 to be blocked.

[0030] The working principle of this embodiment is as follows: when in use, the tee 1 is connected to the underground water supply pipe, and the embedded pipe 11 is also located in the soil, and the threaded barrel 12 is exposed above the ground. When spraying, the riser 2 is threadedly connected to the threaded barrel 12, and then the valve of the water supply pipe is opened. Water can enter the embedded pipe 11 and the riser 2, and then spray out from the nozzle 21 to the surrounding areas to achieve a spraying effect. When not in use, close the valve of the water supply pipe, then rotate and remove the riser 2, and thread the sealing cap 5 to the surface of the threaded barrel 12. Finally, the riser 2 is pulled away and stored in the warehouse.

[0031] Example 2: Figure 2-4 As shown, the difference from Example 1 is that the sealing cap 5 is cancelled, the outer surface of the threaded barrel 12 is threadedly connected to the grafting tube 3, the inner wall of the bottom end of the grafting tube 3 is provided with a thread, the standpipe 2 is threadedly connected to the outer surface of the grafting tube 3, and the outer surface of the top end of the grafting tube 3 is provided with a thread connected to the standpipe 2.

[0032] Specifically, the inner wall of the grafting tube 3 is fixedly connected to the first bracket 31, and a guide hole 32 is opened in the middle of the first bracket 31. A guide rod 33 is slidably inserted into the guide hole 32. The top of the guide rod 33 is fixedly connected to a sealing plate 34. The diameter of the sealing plate 34 is smaller than the inner diameter of the grafting tube 3. A spring 35 is sleeved on the outer surface of the guide rod 33. The spring 35 is located between the first bracket 31 and the sealing plate 34 and can be used to support the sealing plate 34. The top of the inner wall of the grafting tube 3 is fixedly connected to a baffle 36. The baffle 36 is fixedly connected to the top of the inner wall of the grafting tube 3. A through hole 37 is opened in the middle, and the diameter of the through hole 37 is smaller than the diameter of the sealing plate 34. The inner wall of the vertical pipe 2 is fixedly connected to the second bracket 22, and the bottom of the second bracket 22 is fixedly connected to the pressure rod 23. The diameter of the pressure rod 23 is smaller than the diameter of the through hole 37. When the vertical pipe 2 is threadedly connected to the surface of the grafting tube 3, the pressure rod 23 passes through the through hole 37 and presses down the sealing plate 34, so that a gap is generated between the sealing plate 34 and the baffle 36, so that water can enter the through hole 37 from above the sealing plate 34, and then enter the vertical pipe 2.

[0033] Preferably, Figure 4 As shown, the top of the sealing plate 34 is fixedly connected to a plug 38 that is compatible with the through hole 37. After the riser 2 is disassembled, the spring 35 pushes the sealing plate 34 upward to fit the baffle 36, and the plug 38 is inserted into the through hole 37. The top surface of the plug 38 is flush with the top surface of the baffle 36, thereby avoiding the problem of dust remaining in the through hole 37 and being difficult to clean.

[0034] Preferably, a torsion block 39 is fixedly connected to the outer surface of the grafting tube 3 . When installing the grafting tube 3 , a wrench can be used to rotate and install the grafting tube 3 on the surface of the torsion block 39 .

[0035] Example 3:

[0036] like Figure 5-7 As shown, on the basis of Example 2, the outer surface of the grafting tube 3 is slidably sleeved with a positioning sleeve 4, the grafting tube 3 and the positioning sleeve 4 are both circular, and the positioning sleeve 4 can slide and rotate on the surface of the grafting tube 3, and the outer surface of the bottom end of the grafting tube 3 is fixedly connected to a limiting ring 41, and the top of the inner wall of the positioning sleeve 4 is fixedly connected to a pull ring 42, and the limiting ring 41 limits the pull ring 42 so that the positioning sleeve 4 cannot fall off from the grafting tube 3, and the top of the outer surface of the embedded pipe 11 is fixedly connected to a threaded ring 43, and the inner wall of the positioning sleeve 4 is provided with a thread, and the positioning sleeve 4 is threadedly connected to the outer surface of the threaded ring 43, and the pull ring 42 in the positioning sleeve 4 provides downward pressure to the limiting ring 41, thereby limiting the grafting tube 3.

[0037] Specifically, the threads on the outer surface of the threaded ring 43 are in opposite directions to the threads on the outer surface of the threaded barrel 12. After the positioning sleeve 4 is threadedly connected to the surface of the threaded ring 43, the pull ring 42 provides downward pressure on the limiting ring 41. Therefore, when the grafting tube 3 is rotated in the direction of loosening the grafting tube 3 without removing the positioning sleeve 4, the friction between the limiting ring 41 and the pull ring 42 causes the positioning sleeve 4 to rotate in the direction of tightening. Therefore, the interaction of forces makes it impossible to remove the grafting tube 3. Only after the positioning sleeve 4 is rotated and removed can the grafting tube 3 be rotated and removed.

[0038] The working principle of this embodiment is as follows: when in use, after the grafting tube 3 is threadedly connected to the surface of the threaded barrel 12, the positioning sleeve 4 is rotated so that the positioning sleeve 4 is threadedly connected to the surface of the threaded ring 43. When spraying garden plants, the standpipe 2 is taken out from the warehouse, the top of the grafting tube 3 is wiped clean, the dust on the surface of the baffle 36 is wiped clean, and then the standpipe 2 is threadedly connected to the surface of the grafting tube 3. During the connection process, the pressure rod 23 in the standpipe 2 presses down the plug 38, so that a gap is generated between the sealing plate 34 and the baffle 36. The water then flows into the embedded pipe 11 through the gap between the sealing plate 34 and the baffle 36 in the grafting tube 3, and then flows into the riser 2 through the gap between the pressure rod 23 and the through hole 37, and finally is sprayed out from the nozzle 21 to achieve a spraying effect. After the spraying is completed, the riser 2 is rotated and removed, and the spring 35 pushes the sealing plate 34 up to contact the baffle 36 to achieve sealing, and the plug 38 blocks the through hole 37, thereby preventing dust from entering the grafting tube 3.
