Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, specifically a lifting irrigation nozzle for municipal green belts. Background Technology

[0002] Municipal engineering refers to urban infrastructure construction projects, encompassing various public facilities and projects built in cities to meet the needs of residents' lives and urban operations. These include the design and construction of urban parks, squares, street greening, and residential greening projects, as well as the planting of trees, flowers, and other plants to beautify the urban environment. Municipal green belt irrigation sprinklers are devices used for irrigating plants in municipal green belts, capable of evenly spraying water onto the plants in the green belts to meet their water needs for growth.

[0003] However, existing technologies still have the following problems: most traditional municipal green belt irrigation sprinklers are fixed in installation, with fixed spraying height and range. On the one hand, the irrigation coverage of fixed-height sprinklers is limited, making it difficult to meet the differentiated irrigation needs of different green belt terrains and vegetation density. On the other hand, municipal green belt irrigation water is often taken from natural water sources or reclaimed water, which contains a lot of impurities such as silt, dead leaves, and algae. Traditional sprinklers lack effective filtration devices, and impurities can easily clog the sprinkler outlet, affecting the spraying effect and the service life of the sprinkler. Utility Model Content

[0004] To address the issues of adjustable nozzle height and easy clogging, this invention aims to provide a liftable irrigation nozzle for municipal greenbelts.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a lifting municipal green belt irrigation sprinkler head, including a base, a waterproof box fixedly installed on the upper surface of the base, a lifting mechanism fixedly connected to the upper surface of the waterproof box, a sprinkler head support fixedly installed at the top of the lifting mechanism, a sprinkler head body fixedly installed inside the sprinkler head support, a filter device fixedly connected to one end of the sprinkler head body, a pressure hose connected through the other end of the filter device, the lifting mechanism including a cylindrical shell, a lead screw rotatably connected inside the cylindrical shell, a motor fixedly installed inside the waterproof box, the output end of the motor passing through the cylindrical shell and fixedly connected to one end of the lead screw, a guide sleeve threaded onto the outer surface of the lead screw, multiple guide rods fixedly installed on the upper surface of the guide sleeve, a top plate fixedly connected to the top ends of the multiple guide rods, and the upper surface of the top plate fixedly connected to the sprinkler head support.

[0006] Preferably, the filtration device includes a main body, a flange is fixedly installed at one end of the main body, a filter basket is provided on one side of the interior of the main body, one end of the filter basket abuts against the inner wall of one side of the main body, and a sealing ring is fitted on the outer surface of the filter basket.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] This invention utilizes a lifting mechanism and a filtration device in conjunction. A motor-driven lead screw, along with a guide sleeve and guide rod, enables the raising and lowering of the sprinkler head. During irrigation, the sprinkler head is raised to expand the irrigation coverage and improve efficiency; when not irrigating, it is lowered to effectively prevent damage from pedestrians or vehicle collisions. The filter basket in the filtration device effectively intercepts impurities in the water, and the sealing ring ensures a tight seal at the connection points, preventing unfiltered water from flowing around the filter basket. This prevents the sprinkler head from becoming clogged, ensuring continuous and stable operation and reducing the need for frequent repairs and replacements due to clogging.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Figure 1-3As shown, this utility model provides a lifting-type municipal green belt irrigation sprinkler, including a base 11. Fixing holes are distributed on the outer surface of the base 11. The sprinkler is fixed to the installation position of the municipal green belt by bolts and other connecting parts, providing stable support. A waterproof box 12 is fixedly installed on the upper surface of the base 11. A lifting mechanism 13 is fixedly connected to the upper surface of the waterproof box 12. A sprinkler support 14 is fixedly installed at the top of the lifting mechanism 13. A sprinkler body 15 is fixedly installed inside the sprinkler support 14. A filter device 16 is fixedly connected to one end of the sprinkler body 15. A pressure hose 17 is connected to one end of the filter device 16. Water flows through the pressure hose 17 into the filter device 16. The filtered water enters the sprinkler body 15. The height of the sprinkler body 15 and the filter device 16 is adjusted by the lifting mechanism 13.

[0016] The lifting mechanism 13 includes a cylindrical housing 23, inside which a lead screw 24 is rotatably connected. A motor 22 is fixedly installed inside the waterproof box 12. A waterproof wiring hole is opened on one side of the outer surface of the waterproof box 12, providing a channel for the wires of electrical components such as the motor 22 to be connected. Its waterproof properties can prevent external moisture from entering the interior of the waterproof box 12, avoiding damage to electrical components due to moisture and short circuits, and ensuring the normal operation of the motor 22. The output end of the motor 22 passes through the cylindrical housing 23 and is fixedly connected to one end of the lead screw 24. A guide sleeve 25 is threaded onto the outer surface of the lead screw 24. The outer surface of the guide sleeve 25 slides against the inner surface of the cylindrical housing 23, which further guides and constrains its own movement, reduces swaying and deviation during the lifting process, and ensures that the nozzle is accurately raised and lowered to the predetermined position. Multiple guide rods 26 are fixedly installed on the upper surface of the guide sleeve 25. The multiple guide rods 26 are arranged in a ring array and all penetrate the cylindrical shell 23 and slide against the upper inner wall of the cylindrical shell 23. Their function is to ensure that the top plate 27 is subjected to uniform force during the lifting and lowering process, and to ensure the stability of the nozzle support 14 and the nozzle body 15 during lifting and lowering. By restricting the rotation of the guide sleeve 25, it can only move in a straight line along the screw 24, so as to achieve smooth lifting and lowering of the nozzle. The top ends of the multiple guide rods 26 are fixedly connected to the top plate 27. The upper surface of the top plate 27 is fixedly connected to the nozzle support 14. When the motor 22 is energized, it drives the screw 24 to rotate. The guide sleeve 25 is threadedly connected to the screw 24. Under the restriction of the guide rods 26, it can only move in a straight line along the screw 24, thereby driving the top plate 27, the nozzle support 14 and the nozzle body 15 to lift and lower. This realizes the function of raising to expand the range during irrigation, lowering to avoid damage during non-irrigation, and adjusting the height as needed. The filter device 16 includes a main body 18, with a flange 10 fixedly installed at one end of the main body 18. A filter basket 19 is provided on one side of the interior of the main body 18, with one end of the filter basket 19 abutting against the inner wall of one side of the main body 18. A sealing ring 20 is fitted on the outer surface of the filter basket 19. An external thread 21 is formed on the outer surface of the end of the pressure hose 17, and an internal thread is formed on the inner surface of one side of the main body 18. The two are used together to realize the detachable connection between the pressure hose 17 and the main body 18 in the filter device 16. When connected, one end of the filter basket 19 is abutted and fixed against the inner wall of the main body 18. When the pressure hose 17 is disassembled, the filter basket 19 can be detached from the main body 18 at the same time, which is convenient for cleaning and maintenance of the filter basket. The outer surface of the flange 10 and one end of the nozzle body 15 are provided with multiple corresponding connection holes. One end of the nozzle body 15 and one end of the filter device 16 are fixedly connected by multiple bolts, which provides a solid connection strength for the nozzle body 15, prevents it from loosening and falling off under water pressure, and facilitates quick disassembly and installation during maintenance or replacement of parts. Water flows through the pressure hose 17 into the filter device 16. The filter basket 19 in the main body 18 intercepts impurities in the water. The sealing ring 20 ensures the sealing of the connection and prevents unfiltered water from flowing around the filter basket, so that the water entering the nozzle body 15 is clean, avoids nozzle clogging, and ensures normal water spraying and irrigation function.

[0017] Working principle: After the motor 22 is powered on, it rotates, which drives the lead screw 24 to rotate. The guide sleeve 25 is threadedly connected to the lead screw 24. Because the guide rod 26 restricts its rotation, the guide sleeve 25 can only move in a straight line along the lead screw 24, thereby driving the top plate 27, the nozzle support 14 and the nozzle body 15 to rise and fall. The nozzle rises during irrigation and lowers when not irrigating to prevent damage from external forces and allow for adjustment of irrigation height. Water flows through the pressure hose 17 into the filter device 16. The filter basket 19 inside the main body 18 intercepts impurities in the water. The sealing ring 20 ensures the sealing of the connection and prevents unfiltered water from flowing around the filter basket, making the water entering the nozzle body 15 relatively clean and preventing nozzle clogging. The fixing holes on the base 11 are used to install the entire nozzle in a suitable position in the green belt. The pressure hose 17 is connected to the internal thread of the main body 18 through the external thread 21. At the same time, one end of the filter basket 19 is abutted and fixed between the inner walls of the main body 18. During the disassembly of the pressure hose 17, the filter basket 19 can be simultaneously detached from the main body 18 for easy cleaning and maintenance. The nozzle body 15 and the filter device 16 are connected by the flange 10 and bolts to ensure a stable connection and facilitate maintenance.

[0018] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
