[0002] As an important part of the city, environmental greening is of great significance to improving the urban living environment, residents' sense of well-being and environmental protection. Maintaining environmental greening is an important part of municipal work, especially regular sprinkler irrigation of greening to ensure its normal growth. There are two main types of devices for sprinkler irrigation of greening, one is a mobile sprinkler truck, and the other is an automatic sprinkler device buried underground. The latter is widely used in lawn sprinkler irrigation and has the advantage of low cost.

[0003] The embedded sprinkler system currently used for lawn irrigation mainly consists of an underground piping system and sprinkler heads exposed on the ground. The sprinkler heads lack a protective structure, which makes them easily damaged by human trampling. In addition, the water holes of the sprinkler heads are easily clogged by soil, which in turn causes the sprinkler irrigation to be unable to proceed normally, affecting the regular irrigation of the lawn and increasing the equipment maintenance cost.

[0004] For this reason, a municipal greening sprinkler irrigation device is proposed. Utility Model Content

[0005] The purpose of the present invention is to solve the problems mentioned in the above background technology, and the present invention provides a municipal greening sprinkler irrigation device.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] A municipal greening sprinkler irrigation device comprises a mounting box, wherein a water supply branch pipe is fixedly installed through the bottom wall of the mounting box, a side nozzle is fixedly installed on the top surface of the water supply branch pipe, a boost nozzle is fixedly installed on the side of the side nozzle pipe, an irrigation nozzle is fixedly installed on the top surface of the side nozzle pipe, and the side nozzle and the external cover of the irrigation nozzle are provided with a protective cover, the number of the protective covers is two, and the protective covers are symmetrically fitted to each other in a closed cylindrical shape, an elastic movable component for guiding the protective cover is provided on the inner wall surface of the mounting box, a drainage hole is provided on the bottom surface of the mounting box, a filter cartridge is threadedly installed on the inner wall surface of the drainage hole, a return water component connected to the drainage hole is fixedly connected between the bottom surface of the mounting box and the water supply branch pipe, a suction pump is provided on the surface of the water supply branch pipe, and the suction pump is arranged above the lower end of the return water component.

Therefore, they cannot be understood as a limitation on the present invention.

[0026] like Figures 1 to 4 As shown, a municipal greening sprinkler irrigation device includes a mounting box 1, a water supply branch pipe 2 is fixedly installed through the bottom wall of the mounting box 1, a side nozzle 3 is fixedly installed on the top surface of the water supply branch pipe 2, a booster nozzle 4 is fixedly installed on the side of the side nozzle 3, an irrigation nozzle 5 is fixedly installed on the top surface of the side nozzle 3, and the external covers of the side nozzle 3 and the irrigation nozzle 5 are provided with a protective cover 6. There are two protective covers 6, which are symmetrically fitted to each other in a closed cylindrical shape. An elastic movable component 7 for guiding the protective cover 6 is provided on the inner wall surface of the mounting box 1, a drainage hole 9 is opened on the bottom surface of the mounting box 1, and a filter cartridge 10 is threadedly installed on the inner wall surface of the drainage hole 9. A return water component 11 connected to the drainage hole 9 is fixedly connected between the bottom surface of the mounting box 1 and the water supply branch pipe 2, and a suction pump 12 is provided on the surface of the water supply branch pipe 2, and the suction pump 12 is arranged above the lower end of the return water component 11.

[0027] More specifically, irrigation water is pumped into the side nozzle 3 and the irrigation nozzle 5 through the water supply branch pipe 2 and the suction pump 12, and the water sprayed at high speed by the booster nozzle 4 is used to apply force to the left and right protective covers 6 respectively, so that the two protective covers 6 are separated from each other, thereby exposing the irrigation nozzle 5, and the grassland is irrigated by the irrigation nozzle 5. When the irrigation is completed, water is no longer supplied and the booster nozzle 4 no longer sprays high-speed water. Therefore, under the elastic force of the elastic moving component 7, the two protective covers 6 can be reset to seal and protect the irrigation nozzle 5, effectively preventing trampling and soil from entering, thereby extending the service life of the irrigation nozzle 5. During the water spraying process of the booster nozzle 4, the sprayed water accumulates inside the installation box 1, is discharged to the return water component 11 through the drainage hole 9, and is fully filtered by the filter cartridge 10 and then flows back to the water supply branch pipe 2, realizing the reciprocating recycling of the water body, which has the advantage of environmental protection, and the filter cartridge 10 threadedly installed in the drainage hole 9 has the advantage of being easy to disassemble for cleaning and replacement.

[0028] The elastic moving component 7 includes a slide 701, a moving plate 702 and a spring 703. The slide 701 is opened on the front and rear sides of the inner wall of the installation box 1, the moving plate 702 is fixedly installed on the outer surface of the protective cover 6, and the moving plate 702 is slidably installed on the inner wall surface of the slide 701. The spring 703 is fixedly installed on the end surface of the slide 701 away from the irrigation nozzle 5 and is fixedly connected to the surface of the moving plate 702.

[0029] Specifically, during the non-irrigation period, the spring 703 applies a force to the movable plate 702 toward the irrigation nozzle 5, so that the left and right protective covers 6 fit together, sealing and protecting the irrigation nozzle 5, the booster nozzle 4 and the side nozzle 3. When irrigation is in progress, the high-speed water flow ejected by the booster nozzle 4 applies a force to the protective cover 6, so that the protective cover 6 moves away from the irrigation nozzle 5. At this time, the movable plate 702 slides along the inner wall surface of the slide 701 in the direction away from the irrigation nozzle 5, and the spring 703 is compressed. After the irrigation is completed, the spring 703 drives the movable plate 702 and the protective cover 6 to reset.

[0030] A force block 8 is fixedly installed on the inner surface of the protective cover 6. There are several booster nozzles 4 and they are evenly distributed in a circular array on the side of the side nozzle 3. The side surface of the force block 8 close to the side nozzle 3 is a vertical plane. The force block 8 is flush with the side nozzle 3. A bucket-shaped surface 13 is provided on the bottom surface of the inner wall of the installation box 1, and the lowest point of the bucket-shaped surface 13 is concentrated on the top of the drainage hole 9.

[0031] Specifically, the high-speed water flow sprayed from the boost nozzle 4 is borne by the force-bearing block 8. Compared with the water flow directly sprayed on the inner wall side of the arc-shaped protective cover 6, the vertical plane structural characteristics of the force-bearing block 8 can maximize the use of the force of the water flow, thereby improving the efficiency of the high-speed water flow in moving the protective cover 6. By utilizing the structural characteristics of the bucket-shaped surface 13, the water sprayed by the boost nozzle 4 and accumulated in the installation box 1 can be quickly and efficiently discharged through the drainage hole 9.

[0032] The filter cartridge 10 includes a threaded tube 1001, which is threadedly installed on the inner wall surface of the drain hole 9. A filter cover 1002 is fixedly installed on the top surface of the threaded tube 1001. A first handle 1003 is fixedly installed on the top surface of the filter cover 1002. The first handle 1003 is recessed inside the drain hole 9. A secondary adsorption cartridge 1004 is threadedly installed on the inner wall surface of the threaded tube 1001.

[0033] Specifically, by grasping the first handle 1003 and rotating it, the filter cover 1002 and the threaded tube 1001 can be driven to rotate, and the filter cartridge 10 threadedly installed on the inner wall surface of the drain hole 9 can be taken out as a whole, and the secondary adsorption cartridge 1004 threadedly installed in the threaded tube 1001 can also be quickly removed by rotating, which has the advantages of being easy to disassemble, clean and replace. The water body is filtered once through the filter cover 1002, and the tiny particles and dissolved substances in the water body are filtered for the second time through the secondary adsorption cartridge 1004, ensuring the cleanliness of the water body returned to the water supply branch pipe 2 through the return water component 11. While being environmentally friendly and water-saving, it avoids clogging of the irrigation nozzle 5. The first handle 1003 is recessed in the drain hole 9 to avoid it hindering the movement of the protective cover 6.

[0034] The secondary adsorption cylinder 1004 includes a threaded box 10041, which is threadedly installed on the inner wall surface of the threaded tube 1001. An activated carbon bag 10042 is placed inside the threaded box 10041. A water leakage hole 10043 is opened on the bottom wall of the threaded box 10041. A second handle 10044 is fixedly installed on the bottom surface of the threaded box 10041.

[0035] Specifically, by grasping the second handle 10044 and rotating it, the threaded box 10041 can be driven to rotate, so that the secondary adsorption cylinder 1004 can be quickly disassembled and assembled from the lower side of the threaded tube 1001. After removing the threaded box 10041, the activated carbon bag 10042 placed therein can be cleaned or replaced. The activated carbon bag 10042 further adsorbs and removes impurities in the water, and the water flows downward through the leakage hole 10043 to the return water component 11, completing the filtration and reflux work.

[0036] The return water assembly 11 includes a fixed block 111, which is fixedly installed on the bottom surface of the installation box 1. A return water pipe 112 is fixedly installed inside the fixed block 111. The upper end of the return water pipe 112 is located directly below the drain hole 9, and the lower end of the return water pipe 112 is fixedly connected to the surface of the water supply branch pipe 2.

[0037] Specifically, the suction pump 12 works to suck water, and the water flowing back under the action of gravity enters the water supply branch pipe 2 through the return pipe 112. The check valve 113 is used to ensure that the water can only enter the water supply branch pipe 2 through the return pipe 112, and cannot flow back into the return pipe 112 through the water supply branch pipe 2.

[0038] In summary: irrigation water is pumped into the side nozzle 3 and the irrigation nozzle 5 through the water supply branch pipe 2 and the suction pump 12, and the water sprayed at high speed by the booster nozzle 4 is used to apply force to the left and right protective covers 6 respectively, so that the two protective covers 6 are separated from each other, thereby exposing the irrigation nozzle 5, and the grassland is irrigated by the irrigation nozzle 5. When the irrigation is completed, water is no longer supplied, and the booster nozzle 4 no longer sprays high-speed water. Therefore, under the elastic force of the elastic moving component 7, the two protective covers 6 can be reset to seal and protect the irrigation nozzle 5, effectively preventing trampling and soil from entering, thereby extending the service life of the irrigation nozzle 5; during the water spraying process of the booster nozzle 4, the sprayed water accumulates inside the installation box 1, is discharged to the return water component 11 through the drainage hole 9, and is fully filtered by the filter cartridge 10 and then flows back to the water supply branch pipe 2, realizing the reciprocating recycling of the water body, which has the advantage of environmental protection, and the filter cartridge 10 threadedly installed in the drainage hole 9 has the advantage of being easy to disassemble for cleaning and replacement.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention.
