DETAILED DESCRIPTION

[0029] In order to make the technical problems, technical solutions and beneficial effects of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0030] Please refer to Figures 1 to 5 , a landscape greening maintenance device is described. A landscape greening maintenance device, comprising a water delivery pipe 1, a plurality of water outlet pipes 2, a plurality of telescopic pipe assemblies 3 and a plurality of water spraying pipes 4, the plurality of water outlet pipes 2 are located on one side of the water delivery pipe 1 and are connected to the water delivery pipe 1 at one end, and the plurality of water outlet pipes 2 are arranged at equal intervals along the axial direction of the water delivery pipe 1; the plurality of telescopic pipe assemblies 3 are connected to the plurality of water outlet pipes 2 one by one, have axial telescopic freedom, and are connected to the other end of the water outlet pipe 2 at one end; the plurality of water spraying pipes 4 are provided with a plurality of water spraying holes 41 on the side thereof along the axial direction, and the plurality of water spraying pipes 4 are connected to the other end of the plurality of telescopic pipe assemblies 3 respectively, and the water spraying pipe 4 is used for spraying water towards the landscape greening and can rotate around the telescopic pipe assembly 3 in the axial and circumferential directions when spraying water.

[0031] Compared with the prior art, the landscape greening maintenance device provided by the utility model can adjust the height of water spraying by arranging the telescopic pipe assembly 3 on the plurality of water outlet pipes 2, and the telescopic pipe assembly 3 can be easily disassembled and assembled through the clamping and connecting of the telescopic pipe assembly 3 and the water outlet pipe 2, so that the technical problem of the complicated connection mode of the existing irrigation device, which is not easy to disassemble and time-consuming and labor-consuming when the irrigation device needs to be replaced, is solved, and the improved connection mode is easy and fast to disassemble, time-saving and labor-saving, and does not affect the surrounding greening facilities.

[0032] The water delivery pipe 1 is a water pipe with a diameter larger than that of the water outlet pipe 2, one end of which is connected to a water source, and the other end of which can be closed or connected to other pipes.

[0033] In some examples, please refer to Figures 1-3The telescopic pipe assembly 3 includes an inlet pipe 31 and a telescopic pipe 32. One end of the inlet pipe 31 is engaged with the other end of the outlet pipe 2. One end of the telescopic pipe 32 is inserted into the other end of the inlet pipe 31, and the other end is used to connect multiple sets of spray pipes 4. The telescopic pipe 32 has the freedom to slide and insert within the inlet pipe 31, and the insertion depth of the telescopic pipe 32 within the inlet pipe 31 is adjustable. The inner diameter of the inlet pipe 31 is slightly larger than the outer diameter of the telescopic pipe 32. The two work together to extend and retract, without forming gaps between the inlet pipe 31 and the telescopic pipe 32, preventing water leakage. By adjusting the insertion depth of the telescopic pipe 32 within the inlet pipe 31, the spray height can be adjusted, facilitating watering of the landscape greenery. There is a certain friction between the inlet pipe 31 and the telescopic pipe 32. After adjusting the position of the telescopic pipe 32, it can be locked in a certain position within the inlet pipe 31. For example... Figure 3 As shown, the bottom of the inlet pipe 31 and the outlet pipe 2 are sealed together to ensure maximum water leakage. However, in actual operation, a small amount of water leakage between the inlet pipe 31 and the outlet pipe 2 is permissible. Since the water pipe 1 is located in the garden irrigation area, a small amount of water leakage will not affect the garden greenery; on the contrary, it will help irrigate the greenery. The materials of the telescopic pipe 32 and the inlet pipe 31 can be existing technologies. The spray pipes 4 located above the telescopic pipe 32 are in three groups, evenly distributed along the circumference.

[0034] To prevent the telescopic tube 32 from slipping or coming out of the inlet pipe 31, in some embodiments, please refer to... Figures 2-3The inner wall of the water inlet pipe 31 is provided with a limiting groove 311 along its axial direction, and the outer wall of the telescopic pipe 32 is provided with a limiting block 321 near the end of the water inlet pipe 31. The limiting block 321 is slidably connected in the limiting groove 311, and the limiting groove 311 is suitable for preventing the telescopic pipe 32 from slipping out of the water inlet pipe 31. The length of the limiting groove 311 is less than the length of the inlet pipe 31. It can be set in a stepped shape. One end of the limiting groove 311 can be connected to the end of the inlet pipe 31, which facilitates the insertion of the limiting block 321 into the limiting groove 311. After being inserted into the limiting groove 311, the telescopic tube 32 is rotated so that the limiting block 321 is placed in the vertically set limiting groove 311 (the limiting groove 311 is located in the middle of the inlet pipe 31 and is set parallel to the axial direction of the inlet pipe 31). By telescopically extending and retracting the telescopic tube 32 in the inlet pipe 31, the limiting block 321 always slides up and down in the vertically set limiting groove 311 and will not slip out of the limiting groove 311, thus ensuring that the telescopic tube 32 will not come out of the inlet pipe 31. To disassemble the telescopic tube 32, simply rotate it in the opposite direction to allow the limiting block 321 to enter the limiting groove 311 located at the upper end of the vertical limiting groove 311. This facilitates the sliding of the limiting block 321 out of the limiting groove 311, thus separating the telescopic tube 32 from the water inlet pipe 31. Preferably, the limiting block 321 can be designed as a structural component with a certain degree of elasticity. When installed into the limiting groove 311, it is allowed to have a certain amount of compression, which facilitates the mutual installation of the limiting block 321 and the limiting groove 311. However, under normal conditions, the limiting block 321 will not be allowed to slide out of the limiting groove 311.

[0035] In some embodiments, please refer to Figures 1-3 and Figure 5 A small convex ring 5 is fitted around the outer circumference of the end of the outlet pipe 2 furthest from the supply pipe 1. The outer diameter of the end of the small convex ring 5 furthest from the supply pipe 1 is smaller than the outer diameter of its other end. One end of the telescopic pipe 32 assembly 3 is engaged with the small convex ring 5. A large convex ring 6 is also fitted around the outer circumference of the outlet pipe 2. The maximum diameter of the large convex ring 6 is larger than the maximum diameter of the small convex ring 5. The large convex ring 6 is located between the small convex ring 5 and the supply pipe 1. The outer diameter of the end of the large convex ring 6 furthest from the supply pipe 1 is larger than the outer diameter of its other end. Figure 3 As shown, the small convex ring 5 is located at the upper end of the water outlet pipe 2, and the upper end of the small convex ring 5 is flush with the upper end of the water outlet pipe 2, while the large convex ring 6 is located below the small convex ring 5, and the two are spaced apart.

[0036] like Figure 5As shown in some embodiments, a spring 33 is connected to the inner wall of the telescopic pipe assembly 3 near the water supply pipe 1. The spring 33 has a radial extension and retraction degree along the telescopic pipe assembly 3. One end of the spring 33 is connected to the inner wall of the telescopic pipe assembly 3, and the other end is connected to a latch 34. The latch 34 is adapted to be inserted into the gap 35 formed between the small convex ring 5 and the large convex ring 6 to lock and fix the telescopic pipe assembly 3. Spring 33 can elastically push the latch 34 to move, so as to push the latch 34 into the above-mentioned gap 35. The upper length of the latch 34 is greater than the lower length. When installing the water inlet pipe 31 onto the water outlet pipe 2, the inner diameter of the water inlet pipe 31 is greater than the inner diameter of the water outlet pipe 2. At this time, the water inlet pipe 31 can be directly inserted into the water outlet pipe 2 in the direction from top to bottom. At this time, the latch 34 gradually contacts the small convex ring 5. Then, as the water inlet pipe 31 moves down, the push of spring 33 can lock the latch 34 into the gap 35. Since the outer diameter of the large convex ring 6 is large, the latch 34 is not allowed to continue to move downward. At this time, the latch 34 is fixed in the gap 35, thus realizing the locking and fixing of the water inlet pipe 31. When it is necessary to disassemble the water inlet pipe 31, the worker can use a tool to move the latch 34 towards the spring 33, thus moving the latch 34 and simultaneously pulling the water inlet pipe 31 upwards. The latch 34 can pass through the side of the small convex ring 5, thereby detaching the water inlet pipe 31 from the water outlet pipe 2. In this embodiment, at least two latches 34 and their connected structural components are provided, evenly distributed along the circumference of the inner wall of the water inlet pipe 31.

[0037] In some embodiments, please refer to Figure 5 To enable the latch 34 to move radially along the inlet pipe 31 and ensure the locking effect on the inlet pipe 31, a groove 36 is provided on the inner wall of the telescopic pipe assembly 3 near the water supply pipe 1. A limit rod 37 is provided in the groove 36. One end of the limit rod 37 is connected to the inner wall of the telescopic pipe assembly 3. The limit rod 37 is axially along the radial direction of the telescopic pipe assembly 3. A spring 33 is sleeved on the outer periphery of the limit rod 37 and located in the groove 36. The latch 34 is provided with an insertion hole extending inward at the end near the inner wall of the telescopic pipe assembly 3. The end of the limit rod 37 away from the telescopic pipe assembly 3 is inserted into the insertion hole. The spring 33 is adapted to elastically push the latch 34 along the bearing of the limit rod 37 so that the latch 34 is engaged in the gap 35. The depth of the groove 36 is less than the wall thickness of the inlet pipe 31. The groove 36 is arranged in a ring. Multiple limiting rods 37 are evenly distributed in a ring along the inlet pipe 31. When the inlet pipe 31 is installed on the outlet pipe 2, multiple locking tenons 34 can be moved simultaneously by the push of the small convex ring 5, and can also be simultaneously locked into the gap 35 with the push force of the spring 33, thereby realizing the locking and fixing of the inlet pipe 31 on the outlet pipe 2.

[0038] In some embodiments, please refer to Figure 5A waterproof rubber gasket is connected to the inner wall of the telescopic pipe assembly 3 near the water supply pipe 1. The waterproof rubber gasket has a round hole in its center for a small convex ring 5 to pass through and fits snugly against it. The waterproof rubber gasket seals the gap between the telescopic pipe assembly 3 and the small convex ring 5. The waterproof rubber gasket provides a seal, preventing large-scale water leakage. A small amount of water leakage is permissible and will not affect watering the landscaping. When installing the inlet pipe 31 onto the outlet pipe 2, the waterproof rubber gasket is positioned above the latch 34, without affecting its sealing effect. The round hole facilitates water flow. This waterproof rubber gasket is an existing technology product with good sealing performance.

[0039] In some embodiments, please refer to Figure 4 The telescopic pipe assembly 3 is connected to the water spray pipe 4 at one end, and a turntable 38 is rotatably connected inside. The turntable 38 has a degree of freedom to rotate circumferentially around the telescopic pipe assembly 3. The turntable 38 has a through hole in the middle suitable for water flow. The end of the turntable 38 away from the water supply pipe 1 is connected to a hollow rotating ball 39. The outer wall of the rotating ball 39 is connected to one end of multiple sets of water spray pipes 4. The multiple sets of water spray pipes 4 are arranged in a ring array around the rotating ball 39. Water in the water supply pipe 1 is sprayed out sequentially through the water outlet pipe 2, the telescopic pipe assembly 3, the turntable 38, the rotating ball 39 and the multiple sets of water spray pipes 4. The reaction force of the water flow during spraying drives the turntable 38 to rotate. The turntable 38 can rotate. Through the reaction force of the water flow, the water flowing out provides a certain torque or rotational force to the rotating ball 39, causing the turntable 38 to rotate together. The rotating ball 39 is hemispherical and hollow inside, with its lower end fixedly connected to the upper end of the turntable 38. One end of the water spray pipe 4 connects to the inside of the rotating ball 39, allowing water to enter the water spray pipe 4 from inside the rotating ball 39 and then be sprayed out from the water spray hole 41. The turntable 38 is annular, with internal through-holes facilitating water flow. The outer circumferential wall of the turntable 38 is slidably connected to the inner wall of the telescopic pipe 32, allowing a small amount of water to leak out between the turntable 38 and the telescopic pipe 32. The turntable 38 can slide on the inner wall of the telescopic pipe 32 during rotation, while a large amount of water passes through the through-holes.

[0040] In some embodiments, please refer to Figure 4The inner wall of the telescopic tube assembly 3 is provided with an annular rotating groove 310. The turntable 38 is rotatably connected within the rotating groove 310. Multiple slots are provided on both the upper and lower surfaces of the turntable 38, and ball bearings 311 are installed within each slot. The ball bearings 311 are suitable for rolling contact with the telescopic tube assembly 3. To ensure that the turntable 38 can rotate stably within the telescopic tube 32 and will not detach from it, the rotating groove 310 is annularly provided on the inner wall of the telescopic tube 32. The depth of the rotating groove 310 is less than the thickness of the telescopic tube 32, allowing the turntable 38 to rotate within it. Half of the ball bearing 311 is located within the slot, and the other half protrudes from the slot. The turntable 38 can be installed into the rotating groove 310 by assembling multiple blocks. During installation, the multiple blocks are first installed within the rotating groove 310, and then assembled within the rotating groove 310 to form the turntable 38. This method facilitates the installation of the turntable 38. Alternatively, a cap can be installed at the upper end of the telescopic tube 32. The rotating groove 310 is located at the upper end of the telescopic tube 32. After the turntable 38 is installed in the rotating groove 310, the cap can be placed on the upper end of the telescopic tube 32. The cap is annular, with the rotating ball 39 installed in the middle. The function of the cap is to prevent the turntable 38 from moving upward and to prevent the turntable 38 from falling off the upper end of the telescopic tube 32. The ball bearing 311 reduces the friction between the turntable 38 and the telescopic tube 32, making the rotation of the water spray pipe 4 smoother.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
