Description

Technical Field

[0001] This utility model relates to the technical field of greening irrigation equipment, specifically to a greening irrigation device based on urban management. Background Technology

[0002] Urban greening irrigation systems are specialized irrigation systems designed for public green spaces such as municipal green areas, roadside green belts, urban parks, pocket parks, elevated greenbelts, and riverbanks. Their core purpose is to serve public green assets and align with urban management goals. With water conservation, high efficiency, low disturbance, safety, landscape harmony, and ease of operation and maintenance as their core principles, they replace traditional manual watering, becoming a core infrastructure for urban greening maintenance and directly supporting the preservation of the city's appearance and the improvement of the ecological environment. Greening irrigation systems include buried sprinklers, seepage irrigation equipment, and misting equipment.

[0003] Currently, some urban parks use underground sprinklers, which typically consist of a water pump, a water supply pipe, and sprinklers. The water supply pipe is buried underground in the park, and the sprinklers are installed on the water supply pipe. When it is necessary to water the plants in the park, the water pump in the water supply pipe is turned on, and the sprinklers spray water to water the plants. However, during heavy rain or torrential rain, rainwater splashes mud from the ground. Traditional sprinklers do not have a protective structure, and the splashed mud will splash onto the nozzles. If the mud splashed onto the nozzles is not cleaned in time, it will gradually solidify as the water evaporates. The mud combines with the minerals (scale) and biological slime remaining in the nozzles to form a hard composite blockage. Over time, the nozzle orifice diameter becomes smaller or even completely blocked, resulting in a significant reduction in the uniform spraying area, causing the green space to dry out, and thus making it inconvenient to use. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a greening irrigation device based on urban management, which can effectively solve the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a greening irrigation device based on urban management, comprising: a water supply pipe, one end of which is detachably fitted with a protective pipe, a fixing ring fixedly connected to one side of the inner wall of the protective pipe, a limiting cylinder fixedly connected to the inner wall of the fixing ring, a connecting pipe slidably connected to the inner wall of the limiting cylinder, one end of the connecting pipe extending out of the limiting cylinder, and one end of the connecting pipe fixedly connected to a nozzle, push rods fixedly connected to both sides of the lower end of the nozzle, push plates fixedly connected to one end of each of the two push rods, and sliding grooves penetrating both sides of the upper end of the fixing ring, with the outer surfaces of the two push rods slidably connected within the two sliding grooves respectively.

[0006] As a further preferred embodiment of this technical solution, a spring is sleeved on one side of the outer surface of the push rod, and the two ends of the spring are respectively fixedly connected to the fixing ring and one side of the push rod.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] This utility model provides a technical solution: such as Figure 1 - Figure 6As shown in this embodiment, a greening irrigation device based on urban management includes: a water supply pipe 1, a protective pipe 2 detachably installed at one end of the water supply pipe 1, a fixing ring 27 fixedly connected to one side of the inner wall of the protective pipe 2, a limiting cylinder 22 fixedly connected to the inner wall of the fixing ring 27, a connecting pipe 23 slidably connected to the inner wall of the limiting cylinder 22, one end of the connecting pipe 23 extending out of the limiting cylinder 22, and a nozzle 21 fixedly connected to one end of the connecting pipe 23, push rods 24 fixedly connected to both sides of the lower end of the nozzle 21, push plates 25 fixedly connected to one end of each of the two push rods 24, and sliding grooves penetrating both sides of the upper end of the fixing ring 27, with the outer surfaces of the two push rods 24 slidably connected in the two sliding grooves respectively.

[0019] By turning off the water pump 12, water is no longer supplied to the protective pipe 2. The water stops pushing the push plate 25 upward. The nozzle 21, under its own weight and the tension of the spring 26, slides into the protective pipe 2. The protective cover 3 moves to one end of the protective pipe 2, thereby protecting the nozzle of the nozzle 21 and blocking dust in the air and mud splashed by rainwater. This prevents the nozzle of the nozzle 21 from becoming clogged and prevents the spray range of the nozzle 21 from shrinking, thus preventing the green area from becoming dry.

[0020] like Figure 3 - Figure 5 As shown, a spring 26 is sleeved on one side of the outer surface of the push rod 24. The two ends of the spring 26 are fixedly connected to the fixing ring 27 and one side of the push rod 24, respectively. The spring 26 is used to pull the nozzle 21 into the protective tube 2 to prevent jamming when the nozzle 21 enters the protective tube 2 by gravity, which would prevent the nozzle 21 from fully entering the protective tube 2. The force of water on the push plate 25 is greater than the elastic coefficient of the spring 26.

[0021] like Figure 3 - Figure 5 As shown, a second limiting ring 41 is fixedly connected to the outer surface of the connecting pipe 23. The second limiting ring 41 is slidably connected to the inner wall of the limiting cylinder 22. A first limiting ring 4 is fixedly connected to the other side of the outer surface of the push rod 24. The outer surfaces of the second limiting ring 41 and the first limiting ring 4 are wrapped with a layer of rubber. The second limiting ring 41 is used to seal the gap between the limiting cylinder 22 and the connecting pipe 23. The first limiting ring 4 is used to seal the gap between the sliding groove of the fixed ring 27 and the push rod 24.

[0022] like Figure 3 , Figure 4 and Figure 6As shown, a protective cover 3 is fixedly connected to the top of the nozzle 21. A sealing groove 33 is provided on one side of the lower end of the protective cover 3. A sealing ring 31 is fixedly connected to the outer surface of the protective tube 2. A rubber ring 35 is fixedly connected to the upper end of the sealing ring 31. The rubber ring 35 is snapped into the sealing groove 33. A slot 34 is provided on the other side of the lower end of the protective cover 3. A rubber sheet 32 ​​is fixedly connected to one end of the protective tube 2. The rubber sheet 32 ​​is snapped into the slot 34.

[0023] Through the structural design of the sealing groove 33, rubber ring 35, rubber sheet 32 ​​and slot 34, when the protective cover 3 moves to one end of the protective tube 2, the rubber ring 35 enters the sealing groove 33, and the protective cover 3 seals the gap between the protective tubes 2. The rubber sheet 32 ​​enters the slot 34, further sealing the gap between the protective cover 3 and the protective tubes 2. This structural design makes the protective cover 3 form a labyrinth seal between the protective tubes 2, preventing dust and rainwater mixed with impurities from entering and protecting the nozzle of the spray head 21.

[0024] like Figure 1 and Figure 2 As shown, a protective box 11 is provided on one side of the water supply pipe 1, and the water supply pipe 1 passes through the interior of the protective box 11. A water pump 12 is installed inside the protective box 11, and the output end of the water pump 12 is fixedly connected to the other end of the water supply pipe 1. The protective box 11 is used to protect the water pump 12 and prevent the water pump 12 buried in the soil from being damaged. The water pump 12 is used to deliver water to the protective pipe 2 and the nozzle 21. There are multiple protective pipes 2 on the water pump 12, and the multiple protective pipes 2 are evenly distributed underground in the park.

[0025] This utility model provides a greening irrigation device based on urban management, the specific working principle of which is as follows: When irrigating the park's lawn, the water pump 12 is turned on to deliver water into the protective pipe 2. The water pushes the push plate 25 upward, causing the nozzle 21 to slide out of the protective pipe 2. At the same time, some water enters the nozzle 21 and sprays out from the nozzle to irrigate the park's lawn. After irrigation is complete, the water pump 12 is turned off, stopping the delivery of water into the protective pipe 2. The water stops pushing the push plate 25 upward, and the nozzle 21's own weight and the tension of the spring 26 work together to slide the nozzle 21 back into the protective pipe 2, causing the protective cover 3 to move. At one end of the protective tube 2, the rubber ring 35 enters the sealing groove 33, and the protective cover 3 seals the gap between the protective tubes 2. The rubber sheet 32 ​​enters the slot 34 to further seal the gap between the protective cover 3 and the protective tubes 2. This structural design makes the protective cover 3 form a labyrinth seal between the protective tubes 2, preventing dust and rainwater mixed with impurities from entering, thereby protecting the nozzle of the nozzle 21 and blocking the dust and mud splashed by rainwater from the air, thus preventing the nozzle of the nozzle 21 from becoming clogged.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
