Description

Technical Field

[0001] The invention belongs to the technical field of garden irrigation, and in particular relates to a water-saving device for a garden irrigation system. Background Art

[0002] Garden construction refers to the greening, landscape construction and protection and utilization of scenic resources to provide a beautiful living environment and a place for rest and sightseeing for human beings. Its specific contents include the design and construction of parks and gardens, the greening of historical sites and scenic spots, the greening of residential and various public building environments, the greening of roads, squares and riverside, lakeside and coastal areas, the construction of protective green spaces and greening of abandoned land in cities for the purpose of preventing pollution or maintaining water and soil, the establishment and greening of forest parks and rural rest and sanatorium areas, the protection, repair and utilization of natural scenery including ancient trees and tourist resources, and the construction of botanical gardens and zoos.

[0003] When spraying irrigation is carried out on gardens and green spaces, the amount of water consumed is extremely large. In existing spray irrigation, the irrigation system is usually directly shared with domestic water, which wastes a lot of water resources and is not energy-saving and environmentally friendly.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Summary of the invention

[0005] The purpose of the present invention is to provide a water-saving device for a garden irrigation system, which can collect water resources by itself and save a large amount of domestic water.

[0012] Furthermore, the sleeve is buried underground, and the top of the sleeve is on the ground surface. The sleeve is buried underground, which can increase the aesthetics of the garden.

[0013] Furthermore, it also includes a trigger mechanism for triggering the rainwater collection mechanism to work, the trigger mechanism includes a connecting rod, a mounting column for mounting the connecting rod, and a first contact switch and a second contact switch arranged on the connecting rod; a mounting slot for mounting the connecting rod is formed on the mounting column, the middle part of the connecting rod is rotatably connected in the mounting slot, and the bottom of the mounting slot is provided with two electrode sheets respectively contacting the first contact switch and the second contact switch; one end of the connecting rod is provided with a water receiving box, and the other end is provided with a counterweight block; a water leakage hole is formed at the bottom of the water receiving box. Through the trigger mechanism, when the rainfall is large, the driving component can be triggered to push the flexible collection cover upward to open the flexible collection cover to collect rainwater. When the rainfall becomes smaller, the driving component can be triggered to pull the flexible collection cover downward to close the flexible collection cover. The opening or closing of the flexible collection cover can be controlled in real time, which is more intelligent.

[0014] Furthermore, a shielding plate is provided on the top of the water receiving box, and a plurality of water inlet holes are formed on the shielding plate; the diameter of the water inlet hole is larger than the diameter of the water leakage hole; and the number of the water inlet holes is greater than the number of the water leakage holes.

[0017] After adopting the above structure, the present invention relates to a water-saving device for a garden irrigation system. Compared with the prior art, this case provides a rainwater collection mechanism. When it rains, the flexible collection cover can be opened, and the collected rainwater is collected into a reservoir for storage through the flexible collection cover. When irrigation is needed, the sprinkler pipe directly uses the rainwater collected in the reservoir for spraying, which can save a lot of domestic water and is more energy-efficient.
