Description

Technical Field

[0001] The utility model relates to the technical field of greening irrigation, in particular to an underground irrigation device. Background Art

[0002] Urban greening and sanitation issues have always been a concern, especially in crowded residential areas and specially built green areas. A variety of feasible solutions have been proposed for environmental greening. At present, automatic sprinklers are mostly used to meet the irrigation needs of green areas. However, automatic sprinklers are more suitable for irrigation operations in relatively flat areas such as grasslands without other obstructions. The purpose of uniform irrigation can be achieved through automatic sprinklers. Some of the existing automatic sprinklers are arranged in the shape of water pipes above the ground. They protrude from the ground and can achieve a larger irrigation range during the irrigation process, but they are easy to cause walking obstacles and are easy to trip when passing by them; at the same time, they are easy to affect maintenance equipment when cleaning and maintaining surface vegetation.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN211657058U, which discloses an underground telescopic integrated irrigation device. During irrigation, when the water flow inside the first telescopic tube, the second telescopic tube and the third telescopic tube falls back to its original position, the sealing ball falls down to block the groove to achieve sealing. When air is pumped out, the pressure inside the first telescopic tube, the second telescopic tube and the third telescopic tube decreases, and the second telescopic tube and the third telescopic tube fall back to their original positions, which can adapt to the irrigation of fields with different water level differences such as plains, mountains and hills.

[0004] When the above-mentioned irrigation equipment is in use, since the nozzle head is not protected, foreign objects may easily enter, causing blockage and affecting water irrigation. Moreover, since the irrigation equipment is set in the soil, large objects such as stones in the ground may press on the connection between the sprinkler pipe and the water pipe, which may easily cause leakage at the connection. In addition, when the water pipe is in use for a long time, the scale accumulated inside the water pipe is difficult to clean. Therefore, those skilled in the art provide an underground irrigation device to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0027] See also Figure 1-Figure 4 , an underground irrigation device, comprising an underground pipe 1, a cleaning mechanism 2 is arranged inside the underground pipe 1, a water spray pipe 3 is fixedly connected to the top of the underground pipe 1, an auxiliary mechanism 4 is arranged outside the water spray pipe 3, and a protective mechanism 5 is arranged on the top of the water spray pipe 3;

[0028] The cleaning mechanism 2 includes: circular plates 201 are arranged on both sides of the interior of the buried pipe 1, and the two circular plates 201 are fixedly arranged inside the buried pipe 1 through pillars 202. A shaft column 203 is rotatably connected between the two circular plates 201 through a bearing, and a U-shaped rod 204 is fixedly connected to the top of the shaft column 203, and T-shaped rods 205 are fixedly connected to both sides of the top of the U-shaped rod 204. The outsides of the two T-shaped rods 205 are both sleeved with a sleeve rod 206, and a first spring 207 is arranged on the outside of the two T-shaped rods 205 and below the sleeve rod 206, and a scraper rod 208 is fixedly connected to the top of the sleeve rod 206; through holes that are mutually compatible with the outer sizes of the two T-shaped rods 205 are opened on both sides of the sleeve rod 206.

[0029] Furthermore, when water flows inside the buried pipe 1, the power of the water flow causes the shaft column 203 and the U-shaped rod 204 to rotate, thereby causing the scraper rod 208 to rotate inside the buried pipe 1. The arrangement of the T-shaped rod 205, the first spring 207 and the sleeve rod 206 enables the scraper rod 208 to better adhere to the inner surface of the buried pipe 1, thereby cleaning the scale on the inner surface.

[0030] The auxiliary mechanism 4 includes: a circular plate 401 is fixedly connected to the middle of the outer surface of the water spray pipe 3, a group of auxiliary columns 402 are fixedly connected to the bottom end of the circular plate 401, and one end of the group of auxiliary columns 402 is fixedly connected to the top of the buried pipe 1; the group of auxiliary columns 402 are tightly arranged.

[0031] Furthermore, the provision of the annular plate 401 and a group of auxiliary columns 402 strengthens the firmness between the water spray pipe 3 and the buried pipe 1. Since the buried pipe 1 is provided in the soil, it is possible to prevent large objects such as stones in the ground from compressing the connection between the water spray pipe 3 and the buried pipe 1.

[0032] The protection mechanism 5 includes: a circular ring seat 501 is fixedly connected to the upper part of the interior of the water spray pipe 3, a group of telescopic rods 502 are fixedly connected to the top of the circular ring seat 501, the telescopic ends of the group of telescopic rods 502 are fixedly connected to the bottom end of the protection cover 503, and a second spring 504 is arranged on the outside of the group of telescopic rods 502, a positioning plate 505 is fixedly connected to the top of the water spray pipe 3, and a positioning groove 506 is fixedly connected to the bottom end of the protection cover 503; the positioning groove 506 and the positioning plate 505 are both arranged in a circular ring shape, and the outer size of the positioning plate 505 matches the inner size of the positioning groove 506.

[0033] Furthermore, the transported water flows out through the water spray pipe 3, causing the protective cover 503 to be forced to move upward, and its set of telescopic rods 502 and a set of second springs 504 are stretched, and the positioning plate 505 is separated from the positioning groove 506, so that the water flow can be sprayed out. When not irrigating, the force of the return of the set of second springs 504 causes the set of telescopic rods 502 to shrink, thereby moving the protective cover 503 downward. At the same time, the positioning plate 505 and the internal size of the positioning groove 506 fit together, so that when not irrigating, the water spraying part of the water spray pipe 3 can be protected to prevent foreign matter from entering and causing blockage.

[0034] Working principle: When in use, the external water pump delivers water to the buried pipe 1. When the water flows inside the buried pipe 1, the power of the water flow causes the shaft column 203 and the U-shaped rod 204 to rotate, thereby causing the scraper rod 208 to rotate inside the buried pipe 1. The arrangement of the T-shaped rod 205, the first spring 207 and the sleeve rod 206 can make the scraper rod 208 better adhere to the inner surface of the buried pipe 1, so that the scale on the inner surface can be cleaned. The delivered water flows out through the water spray pipe 3, causing the protective cover 503 to be forced to move upward, and a group of telescopic rods 502 and a group of second springs 504 are stretched, and the positioning plate 505 and The positioning groove 506 is separated to spray water. When not irrigating, the restoring force of a group of second springs 504 causes a group of telescopic rods 502 to shrink, thereby moving the protective cover 503 downward. At the same time, the positioning plate 505 fits the internal size of the positioning groove 506. When not irrigating, the water spraying part of the water spray pipe 3 can be protected to prevent foreign objects from entering and causing blockage. The setting of the annular plate 401 and a group of auxiliary columns 402 strengthens the firmness between the water spray pipe 3 and the buried pipe 1. Since the buried pipe 1 is set in the soil, large objects such as stones in the ground will not compress the connection between the water spray pipe 3 and the buried pipe 1.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
