Description

A landscape greening sprinkler Technical Field

[0001] This utility model relates to the field of sprinkler technology, and more specifically, to a landscape greening sprinkler. Background Technology

[0002] A sprinkler is a device that can water garden plants through a water pipe. For example, the water-saving sprinkler device for garden landscape proposed in application number "CN202121827532.4" includes a base, two connecting blocks and a spray head.

[0003] However, in the above technical solutions, the height adjustment of the sprinkler head relies on manual intervention. When the height of multiple sprinkler heads needs to be adjusted, the user often has to adjust them one by one manually, which not only increases labor costs and management difficulty, but also makes it impossible to adjust the height of the sprinkler heads in a timely and fast manner. Therefore, we propose a landscape greening sprinkler to solve the above problems. Summary of the Invention

[0004] The main purpose of this utility model is to provide a landscape greening sprinkler that solves the problem that the height adjustment of the sprinkler head depends on manual intervention. When the height of multiple sprinkler heads needs to be adjusted, the user often has to adjust them one by one manually, which not only increases labor costs and management difficulty, but also makes it impossible to adjust the height of the sprinkler head in a timely and fast manner.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A landscape greening sprinkler includes a support cylinder, a base plate mounted on the lower surface of the support cylinder, an extension cylinder movably installed through the upper end of the support cylinder, a rotating mechanism mounted inside the extension cylinder, an auxiliary mechanism installed between the support cylinder and the extension cylinder, a flexible hose installed through the lower end of the support cylinder and connected to the lower end of the extension cylinder, a support plate mounted on the lower end of the support cylinder, and a locking plate mounted on the lower end of the extension cylinder. The locking plate is movably installed inside the support cylinder and connected to the support plate. The rotating mechanism includes a locking groove extending through the upper end of the extension cylinder, a rotating tube being locked inside the locking groove, and a connecting pipe being installed through the upper end of the rotating tube. A nozzle is installed at the upper end. A rotating shaft is installed at the lower end of the inner part of the rotating tube. Several fixing plates are installed between the rotating shaft and the rotating tube. A propeller is installed at the lower end of the shaft. The auxiliary mechanism includes a first spring, which is sleeved on the outside of the extension tube. The upper and lower ends of the first spring are respectively in contact with the upper end of the locking plate and the inner part of the support tube. A liquid storage tank is provided at the lower end of the inner part of the extension tube. Through holes are provided at the upper and lower ends of the liquid storage tank. A baffle is movably installed inside the liquid storage tank. The baffle is in contact with the upper end of the inner part of the liquid storage tank. A sealing groove is provided in the middle of the upper surface of the baffle. Several drainage holes are provided at the lower end of the inner part of the sealing groove. A sealing plate is locked inside the sealing groove.

[0007] Preferably, a limiting disc is installed on the outer side of the rotating tube inside the locking groove. The limiting disc is locked inside the locking groove, and a bearing is installed between the limiting disc and the locking groove.

[0008] Preferably, a guide frame is installed in the middle of the interior of the extension tube, and the lower end of the rotating shaft is movably installed with the propeller in the middle of the interior of the guide frame. The upper and lower ends of the guide frame are flared, and the middle of the interior of the guide frame is slender.

[0009] Preferably, guide rods are installed at both ends of the liquid storage tank, and the rods of the guide rods are movably installed inside the baffle.

[0010] Preferably, a second spring is fitted onto the outer side of the guide rod located between the baffle and the liquid storage tank.

[0011] Preferably, an extension frame is installed on the lower surface of the sealing plate, and the extension frame is movably installed through the lower end of the sealing groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) In this utility model, when it is necessary to increase the height of the nozzle, the water flow is accelerated to increase the pressure inside the extension cylinder. When the pressure exceeds the thrust of the second spring, the water flow pushes the baffle to move down. The liquid enters the gap between the support cylinder and the extension cylinder through the through hole and the liquid storage tank, pushing the extension cylinder to move upward with the cooperation of the first spring until the target height is reached. Therefore, it is not necessary to manually adjust the height of each nozzle. The height change of multiple sprayers can be uniformly controlled by the water flow pressure, which solves the problems of time-consuming and labor-intensive traditional manual adjustment and high management difficulty.

[0014] (2) In this utility model, by setting a guide frame inside the extension tube, the upper and lower ends are horn-shaped and the middle is a slender tube-shaped structure, which can produce a pressurizing effect on the water flow. When the water flows through the inside of the guide frame, the high-speed water flow drives the propeller to rotate, and then drives the rotating tube and nozzle to rotate synchronously through the rotating shaft, so as to realize multi-angle spraying work.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

The locking plate 8 is movably installed inside the support cylinder 1 and connected to the support plate 9. The rotating mechanism 4 includes a locking groove 402, which is located through the upper end of the extension cylinder 3. A rotating tube 401 is locked inside the locking groove 402, a connecting pipe 5 is installed through the upper end of the rotating tube 401, and a nozzle 6 is installed at the upper end of the connecting pipe 5. A rotating shaft 405 is installed at the lower end of the rotating tube 401. Several fixing plates 406 are installed between the rotating shaft 405 and the rotating tube 401. A propeller 408 is installed at the lower end of the shaft 405. The auxiliary mechanism 7 includes a first spring 701, which is sleeved on the outside of the extension tube 3. The upper and lower ends of the first spring 701 are respectively attached to the upper end of the locking plate 8 and the inner end of the support tube 1. The lower end of the extension tube 3 is provided with a liquid storage tank 702. The upper and lower ends of the liquid storage tank 702 are respectively provided with through holes 703. The liquid storage tank 702 is movably installed with a baffle 704. The baffle 704 is attached to the upper end of the liquid storage tank 702. The upper surface of the baffle 704 is provided with a sealing groove 707 in the middle. Several drain holes 708 are respectively provided through the lower end of the sealing groove 707. A sealing plate 709 is locked inside the sealing groove 707.

[0025] As shown in Figures 4 to 7, in another embodiment of this utility model, a limiting plate 404 is installed on the outer side of the rotating tube 401 inside the engaging groove 402. The limiting plate 404 is engaged inside the engaging groove 402. A bearing 403 is installed between the limiting plate 404 and the engaging groove 402. A guide frame 407 is installed in the middle of the inside of the extension tube 3. The lower end of the rotating shaft 405 and the propeller 408 are movably installed in the middle of the inside of the guide frame 407. The upper and lower ends of the guide frame 407 are flared, and the middle of the inside of the guide frame 407 is slender. Guide rods 705 are installed at both ends of the inside of the liquid storage tank 702. The rods of the guide rods 705 are movably installed through the inside of the baffle 704. A second spring 706 is sleeved on the outer side of the rod of the guide rod 705 located between the baffle 704 and the liquid storage tank 702. An extension frame 710 is installed on the lower surface of the sealing plate 709. The extension frame 710 is movably installed through the lower end of the inside of the sealing groove 707.

[0026] Water flows into the extension tube 3 through the hose 10, and then flows to the nozzle 6 through the guide frame 407. As the water flows along the guide frame 407, the guide frame 407 is funnel-shaped at the top and bottom and slender in the middle, which pressurizes the water flow. This causes the high-speed water flow to impact the propeller 408, which in turn drives the propeller 408 to rotate. This causes the rotating shaft 405 and the rotating tube 401 to rotate synchronously. The rotating tube 401 then drives the nozzle 6 to rotate through the bearing 403. At the same time, the water flows into the nozzle 6 through the rotating tube 401 and the connecting pipe 5 for spraying.

[0027] Then, when it is necessary to adjust the height of the extension cylinder 3 and the nozzle 6, the water flow is accelerated, which increases the internal pressure of the extension cylinder 3. When the pressure exceeds the thrust of the second spring 706, the water flow pushes the baffle 704 downward. After the baffle 704 moves downward, the liquid in the extension cylinder 3 flows into the gap between the support cylinder 1 and the extension cylinder 3 through the through holes 703 at the upper and lower ends of the liquid storage tank 702. Then, with the liquid pressure, the extension cylinder 3 is pushed upward to overcome the resistance of the first spring 701 until the target height is reached, thus completing the adjustment of the height of the nozzle 6. There is no need for manual adjustment of each nozzle. The height of multiple sprayers can be controlled uniformly by the water flow pressure, saving labor costs.

[0028] Then, when it is necessary to control the extension cylinder 3 and the nozzle 6 to reset, the water flow is reduced, so that the internal pressure of the extension cylinder 3 is reduced, allowing the second spring 706 to push the baffle 704 to move upward and reset, blocking the liquid flow. Then, the first spring 701 pushes the extension cylinder 3 downward, squeezing the liquid between the support cylinder 1 and the extension cylinder 3. Then, the liquid pressure pushes the sealing plate 709 upward to open the drain hole 708, so that the liquid flows into the extension cylinder 3 through the drain hole 708 and is sprayed through the nozzle 6.

[0029] The flexible hose 10 is a magic telescopic water hose that can freely extend and retract with the extension tube 3, avoiding damage to the pipe from being pulled.

[0030] The working principle of this type of landscape greening sprinkler:

[0031] In use, water first enters the extension tube 3 through the hose 10, flows to the nozzle 6 via the guide frame 407, and then pressurizes the water flow as it flows along the guide frame 407. The guide frame 407, with its funnel-shaped upper and lower ends and a slender tube in the middle, impacts the propeller 408, causing it to rotate. This rotation of the propeller 408 drives the shaft 405 and the rotating tube 401 to rotate synchronously. The rotating tube 401 then drives the nozzle 6 to rotate via the bearing 403. Simultaneously, water flows through the rotating tube 401 and the connecting pipe 5 into the nozzle 6 for spraying. When adjusting the height of the extension tube 3 and the nozzle 6, the water flow is increased, increasing the pressure inside the extension tube 3. When the pressure exceeds the thrust of the second spring 706, the water pushes the baffle 704 downwards, and then the baffle... After the plate 704 moves down, the liquid in the extension cylinder 3 flows into the gap between the support cylinder 1 and the extension cylinder 3 through the through holes 703 at the upper and lower ends of the liquid storage tank 702. Then, with the liquid pressure, the extension cylinder 3 is pushed upward to overcome the resistance of the first spring 701 until it reaches the target height, thus completing the adjustment of the nozzle 6 height. Then, when it is necessary to control the extension cylinder 3 and the nozzle 6 to reset, the water flow is reduced, so that the internal pressure of the extension cylinder 3 is reduced, allowing the second spring 706 to push the baffle 704 to move upward to reset, blocking the liquid flow. Then, the first spring 701 pushes the extension cylinder 3 downward to squeeze the liquid between the support cylinder 1 and the extension cylinder 3. Then, the liquid pressure pushes the sealing plate 709 upward to open the drain hole 708, so that the liquid flows into the extension cylinder 3 through the drain hole 708 and is sprayed through the nozzle 6.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
