Description

Technical Field

[0001] This utility model relates to the field of irrigation equipment technology, and in particular to a water-saving irrigation device for landscaping. Background Technology

[0002] Irrigation for greening is a maintenance measure that provides water to garden plants, lawns, green belts, etc. It is the key to maintaining the survival and growth of greening. Based on the water requirements of plants, soil moisture and climate conditions, water is replenished in a reasonable way to avoid drought and water shortage that causes plants to wither, while promoting root development and improving the effect of greening landscape. To ensure irrigation of green spaces without compromising water conservation, sprinkler or drip irrigation systems are commonly used. For example, the Chinese utility model patent CN208924863U discloses a forestry irrigation nozzle. This application includes a main body with a fixed plate at its outer end, a rubber ring on the front, a water inlet at the outer end of the rubber ring, and a connecting terminal at the center of the upper surface of the main body. Water delivery rods are connected to the connecting terminal via steel pipes around it. While this application enables sprinkler irrigation of green spaces, its fixed structure means that if installed outdoors for extended periods, especially for irrigating grasslands, the protruding structure poses a tripping hazard to passersby. Furthermore, its exposed nature makes it susceptible to damage from impacts such as trampling. Summary of the Invention

[0003] The purpose of this utility model is to provide a water-saving irrigation device for landscaping, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A water-saving irrigation device for landscaping includes an outer casing, an inner support fixedly connected inside the casing, an installation groove at the center of the inner support, a double-through connector fixedly connected to the inner support below the installation groove, a threaded groove on the inner support below the double-through connector communicating with the cavity of the double-through connector, a grid tube fixedly connected inside the double-through connector, a central tube fixedly connected to the bottom of the installation groove, the central tube also communicating with the inner cavity of the double-through connector, a sleeve inserted through the outer side of the central tube, several spray pipes fixedly connected to the outer side of the sleeve, a sealing plug inserted through the central tube, a connecting shaft fixedly connected to the upper end of the sealing plug and fixedly connected to the top of the inner sleeve by screws.

[0005] As a further preferred embodiment of this utility model, the bottom and top of the mounting shell are both fixedly connected with skirts, which are used to bury the mounting shell in the soil and fix it with pins.

[0006] As a further preferred embodiment of this utility model, a sealing block is fixedly connected to the bottom of the grid tube. The sealing block is threadedly connected in the screw groove. On the one hand, the grid tube can limit the maximum downward movement of the sealing plug in the central tube, thereby limiting the downward movement of the sleeve through the connecting shaft. On the other hand, it also facilitates the insertion of the sealing plug from the screw groove into the central tube through the double-through connector to assemble and connect with the sleeve without the influence of the limiting frame.

[0007] As a further preferred embodiment of this utility model, a number of ball bearings are rotatably connected to the inner side of the mounting groove and slide against the outer side of the central tube, thereby reducing friction for the radial and axial movement of the central tube.

[0008] As a further preferred embodiment of this utility model, a bevel is provided at the upper position of the inner side of the central tube, so that when the sealing plug moves from the lower position of the central tube to the bevel position, a water flow channel is formed between the inner side of the central tube and the sealing plug, allowing water to enter the nozzle. A limit frame is fixedly connected at the center position of the bevel, which can provide a limiting base for one end of the compression spring mounted on the outside of the connecting shaft.

[0009] As a further preferred embodiment of this utility model, a first sealing ring is fixedly connected to the lower inner side of the central tube, and a second sealing ring is fixedly connected to the outer side of the sealing plug. Both the first and second sealing rings are made of polytetrafluoroethylene (PTFE). While achieving the sealing function between the sleeve and the sealing plug and the outer and inner sides of the central tube respectively, the rotational friction between the sleeve and the sealing plug is reduced. The connecting shaft passes through the limiting frame, and two washers, also made of PTFE, are inserted and connected to the outer side of the connecting shaft. A compression spring is also fitted on the connecting shaft between the two washers. Thus, when the irrigation water in the double-connector pushes the sealing plug upward using its own water pressure, the compression spring is compressed. As a result, the sealing plug drives the nozzle to move upward through the connecting shaft and is positioned above the mounting housing. When the sealing plug moves to the bevel position, the irrigation water in the central tube is diverted to the three nozzles through the channel between the sealing plug and the inner wall of the bevel.

[0010] As a further preferred embodiment of this utility model, several nozzles are fixedly connected to the outside of the spray pipe. The irrigation water inside the spray pipe is sprayed out through the nozzles using its water pressure, thereby generating thrust to drive the sleeve to rotate. This allows the three spray pipes to rotate on their own to irrigate the surrounding greenery without the aid of an external power mechanism.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the device can be buried underground to avoid the risk of people tripping due to protrusion above the ground, and also to reduce external impact damage, thereby improving safety and durability. At the same time, during irrigation, the water pressure pushes the sealing plug upward, which in turn raises the nozzle to the ground. The water flow is diverted through the bevel channel to the nozzle, and is sprayed out through the nozzle to generate thrust, enabling the nozzle to rotate and water evenly. This results in uniform coverage without the need for additional power. The device can automatically switch between working and storage states with the help of water pressure, making it water-saving, efficient, and easy to operate. Attached Figure Description

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figures 1-5 As shown, the present invention provides a water-saving irrigation device for landscaping, including an outer casing 1, an inner support 2 fixedly connected inside the outer casing 1, an installation groove 3 at the center of the inner support 2, a double-through connector 4 fixedly connected below the installation groove 3, a screw groove 5 located below the double-through connector 4, the screw groove 5 communicating with the cavity of the double-through connector 4, and a grid tube 6 fixedly connected inside the double-through connector 4, a central tube 7 fixedly connected to the bottom of the installation groove 3, the central tube 7 also communicating with the inner cavity of the double-through connector 4, a sleeve 8 inserted through the outside of the central tube 7, several spray pipes 9 fixedly connected to the outside of the sleeve 8, a sealing plug 10 inserted through the central tube 7, a connecting shaft 11 fixedly connected to the upper end of the sealing plug 10 and fixedly connected to the top of the inner sleeve 8 by screws.

[0016] like Figures 1-2 As shown, the bottom and top of the mounting shell 1 are both fixedly connected with skirts 21, which are used to bury the mounting shell 1 in the soil and fix it with pins.

[0017] like Figures 3-5 As shown, a sealing block 20 is fixedly connected to the bottom of the grid tube 6. The sealing block 20 is threaded into the threaded groove 5. The grid tube 6 can limit the maximum downward movement of the sealing plug 10 in the central tube 7, thereby limiting the downward movement of the sleeve 8 through the connecting shaft 11. On the other hand, it also facilitates the insertion of the sealing plug 10 from the threaded groove 5 into the central tube 7 through the double-connector 4 for assembly and connection with the sleeve 8 without the influence of the limiting bracket 14. Several ball bearings 12 are rotatably connected to the inner side of the mounting groove 3 and slide against the outer side of the central tube 7 to facilitate the radial movement of the central tube 7. In addition to axial movement to reduce friction, a bevel 13 is provided on the upper inner side of the central tube 7, allowing the sealing plug 10 to move from the lower inner side of the central tube 7 to the bevel 13 position, thus creating a water flow channel between the inner side of the central tube 7 and the sealing plug 10, allowing water to enter the nozzle 9. A limit bracket 14 is fixedly connected to the center of the bevel 13, providing a limiting base for one end of the compression spring 18 mounted on the outside of the connecting shaft 11. A first sealing ring 15 is fixedly connected to the lower inner side of the central tube 7, and a second sealing ring 16 is fixedly connected to the outside of the sealing plug 10. Both the first sealing ring 15 and the second sealing ring 16 are made of polytetrafluoroethylene (PTFE). While achieving the sealing function between the sleeve 8 and the sealing plug 10 and the outer and inner sides of the central tube 7 respectively, they also reduce the rotational friction between the sleeve 8 and the sealing plug 10. The connecting shaft 11 passes through the limiting frame 14. Two washers 17, also made of PTFE, are inserted and connected to the outside of the connecting shaft 11. A compression spring 18 is also fitted onto the connecting shaft 11 between the two washers 17. Thus, when the irrigation water in the double-connector 4 uses its own water pressure to push the sealing plug 10 upwards, it compresses the spring 18. 8. When compressed, the sealing plug 10 drives the nozzle 9 to move upward through the connecting shaft 11 and position it above the mounting housing 1. When the sealing plug 10 moves to the bevel 13 position, the irrigation water in the central pipe 7 is diverted to the three nozzles 9 through the channel between the sealing plug 10 and the inner wall of the bevel 13. Several nozzles 19 are fixedly connected to the outside of the nozzles 9. The irrigation water in the nozzles 9 is sprayed out through the nozzles 19 using its water pressure, thereby generating thrust to drive the sleeve 8 to rotate. This allows the three nozzles 9 to rotate on their own to irrigate the surrounding greenery without the aid of an external power mechanism.

[0018] It should be noted that this utility model is a water-saving irrigation device for landscaping. During installation, the outer casing 1 is buried in the soil through the skirt plate 21 and fixed with pins. At the same time, several double-connector joints 4 of the device can be connected through buried pipes and connected to the municipal greening water source pump. When the irrigation operation is started, when the water source passes through the double-connector joint 4, the water flow in the double-connector joint 4 forms water pressure, pushing the sealing plug 10 in the central pipe 7 upward, causing the compression spring 18 on the outside of the connecting shaft 11 to be compressed and contracted. During the upward movement of the sealing plug 10, the second sealing spring 18 on its outside is compressed and contracted. The sealing ring 16 fits tightly with the first sealing ring 15 inside the central tube 7 to ensure a sealing effect. At the same time, the polytetrafluoroethylene material reduces the friction between the two relative to each other. When the sealing plug 10 moves to the bevel 13 position of the central tube 7, the water flows through the channel between the sealing plug 10 and the inner wall of the bevel 13 and is diverted to the three nozzles 9 outside the sleeve 8. Then, the water in the nozzle 9 is sprayed out from the nozzle 19 with the help of water pressure. The reverse thrust generated when spraying drives the sleeve 8 to rotate around the central tube 7, so as to achieve uniform irrigation of the surrounding greenery without the need for additional power. After irrigation, the compression spring 18 returns to its original position due to the loss of water pressure, which in turn pushes the sealing plug 10 downward. The sealing plug 10 drives the sleeve 8 to move downward synchronously through the connecting shaft 11. The sleeve 8 then drives the three outer nozzles 9 to move downward and be stored in the mounting housing 1, so that the nozzles 9 are not exposed on the ground surface.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
