Description

Technical Field

[0001] The present invention relates to the technical field of garden irrigation, and in particular to an environmentally friendly and water-saving garden irrigation device. Background Art

[0002] With the acceleration of urbanization and the increasing demand for greening, garden irrigation technology plays an important role in modern landscape maintenance. Traditional irrigation methods (such as flooding and furrow irrigation) have problems such as water waste and low irrigation efficiency, making it difficult to meet the needs of refined and intelligent garden maintenance.

[0003] In recent years, with the development of the Internet of Things and automation technologies, smart irrigation systems have gradually been applied to gardening. For example, some systems use data from soil moisture sensors or weather stations to adjust irrigation levels.

[0004] However, for areas with small land area and high soil moisture requirements, soil moisture sensors and solenoid valves are used to adjust the irrigation amount. Since each data transmitted by the soil moisture sensor is a humidity value, the solenoid valve adjusts the irrigation amount to a fixed amount within a certain period of time. This can easily lead to excessive or insufficient irrigation in a short period of time, resulting in water waste or insufficient soil moisture. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that in areas with small land area and high soil moisture requirements, soil moisture sensors and solenoid valves are used to adjust the irrigation amount, and the irrigation amount in a short period of time is too large or too small, resulting in water resource waste or insufficient soil moisture.

DETAILED DESCRIPTION

[0048] The present invention will be further explained below with reference to the accompanying drawings.

[0049] like Figure 1-4 As shown, the present invention provides an environmentally friendly and water-saving garden landscape irrigation device, comprising: a filtered water tank 1, a water recovery unit 2 and a spraying unit 3.

[0050] The filtered water tank 1 is connected to the water recovery unit 2 through the first connecting pipe 4, and the water recovery unit 2 is connected to several spraying units 3 through the second connecting pipe 5. The water in the filtered water tank 1 flows into the water inlet channel 23 in the water recovery unit 2 through the first connecting pipe 4, and then enters the spraying unit 3 through the second connecting pipe 5.

[0051] A plurality of permeation holes 21 are provided on both sides of the water recovery unit 2 . A permeation membrane is installed inside each permeation hole 21 . Excess water in the soil passes through the permeation membrane and enters the water recovery unit 2 for storage.

[0052] The push plate 221 in the water volume control assembly 22 is slidably connected to the groove provided on the water recovery unit 2 , and the groove limits the sliding distance of the push plate 221 , thereby limiting the rotation angle of the rotating rod.

[0053] When the amount of water in the water recovery unit 2 increases, the water pushes the push plate 221 to move upward, driving the push rod 222 to move upward, and the push rod 222 drives the rotating rod 223 to rotate. The rotating rod 223 drives the main gear 225 and the sub-gear 226 to rotate through the first connecting shaft 224, thereby driving the second connecting shaft 227 to rotate. The second connecting shaft 227 pushes the blocking block 228 along the slide groove into the water inlet channel 23 through the threaded action, thereby realizing dynamic control of the amount of water flowing through the water inlet channel 23.

[0054] In this embodiment, considering that the natural water pressure is usually small, the push plate 221 and the push rod 222 adopt a hollow structure and are made of lightweight plastic material, so that the entire push plate 221 and the push rod 222 have a small mass, which enables the push plate 221 to float on the water recovery unit 2 and move with the rise or fall of the water level in the water recovery unit 2. The main gear 225 has a larger number of teeth than the sub-gear 226, among which the number of teeth of the main gear 225 is preferably about 5 times the number of teeth of the sub-gear 226, and this multiple can be adjusted according to actual needs and space.

[0055] like Figure 5-6 As shown, a filter screen 11 is provided in the water inlet chamber of the filtered water box 1 , a cleaning component 12 is provided on one side of the filter screen 11 , and the cleaning component 12 is threadedly connected to the top of the filtered water box 1 .

[0056] By rotating the second knob 127 , the rotating shaft 122 is driven to rotate, thereby driving the scraper 124 to clean the mesh surface of the filter 11 . The dirt after cleaning will fall into the storage box, thereby preventing the filter 11 from being blocked.

[0057] When the cleaning assembly 12 needs to be cleaned, the first knob 126 is turned to separate the connecting cover 121 from the top of the filtered water tank 1, thereby taking out the entire cleaning assembly 12, making it easier to clean the cleaning assembly 12 and keep it clean.

[0058] In this embodiment, the filter screen 11 is semicircular, and a limiting groove 128 is provided on the connecting cover 121. The limiting groove 128 limits the limiting block 127 provided on the second knob 127, thereby limiting the rotation angle of the second knob 127, so that the scraper 124 moves within the mesh surface of the filter screen 11, thereby improving efficiency.

[0059] like Figure 7-9 As shown, the spray unit 3 includes a nozzle 31 and a third connecting pipe 32, and a first connecting member 331 and a second connecting member 333 are fixed on the third connecting pipe 32. The first connecting member 331 is identical to the second connecting member 333 through a rotating member 332, wherein the top end of the rotating member 332 is rotatably connected to the first connecting member 331 through a sliding connecting block 334, and the bottom end thereof is rotatably connected to the second connecting member 333 through another sliding connecting block 334.

[0060] The top end of the third connecting pipe 32 is connected to the nozzle 31 , and the bottom end thereof is connected to the second connecting pipe 5 . Water flows from the second connecting pipe 5 into the third connecting pipe 32 , passes through the detection assembly 33 , and finally flows into the nozzle 31 to be sprayed out.

[0061] During testing, the rotating member 332 is rotated to adjust the through hole 335 on it, and the overlapping area with the through holes 335 of the upper and lower first connecting members 331 and the second connecting member 333 is adjusted, thereby adjusting the amount of water entering the nozzle 31, and then observing the changes in the amount of water sprayed out of the nozzle 31 to check whether the nozzle 31 is blocked.

[0062] The present invention works as follows:

[0063] First, the water recovery unit 2 is partially buried in the soil of the irrigation area, and then the filtered water tank 1 and the spraying unit 3 are connected through the first connecting pipe 4 and the second connecting pipe 5.

[0064] Turn on the water pump again, and the water is filtered through the filter screen 11 in the filtered water tank 1 and flows into the water inlet channel 23, and then flows into the spraying unit 3 through the second connecting pipe 5 for spraying. During the irrigation process, excess water will flow into the water recovery unit 2 through the infiltration hole 21. The rising water level will push the push plate 221 to move upward, thereby driving the rotating rod 222 to rotate, so that the blocking plate 228 enters the water inlet channel 23, reducing the amount of water entering the spraying unit 3.

[0065] The present invention adjusts the water volume with the external soil through the infiltration hole 21 on the water recovery unit 2. When the water volume in the soil is high, the excess water will flow into the water recovery unit through the infiltration hole 21. As more water flows into the water recovery unit 2, the push rod 222 is pushed upward, thereby driving the main gear 225 and the sub-gear 226 to rotate, and further driving the second connecting shaft 227 to rotate. The second connecting shaft 227 pushes the blocking block 228 to slide into the water inlet channel 23 through the threaded action, reducing the amount of water entering the spraying unit 3. When the water volume in the soil is low, water will flow into the soil from the infiltration hole 21 to increase the soil moisture. At this time, the push rod 222 moves downward, the blocking block 228 slides out of the water inlet channel 23, and the amount of water entering the spraying unit 3 increases. The above method can realize dynamic regulation of the irrigation amount of the spraying unit, thereby avoiding excessive or insufficient irrigation in a short period of time, resulting in waste of water resources or insufficient soil moisture.

[0066] It is understood from common technical knowledge that the present invention may be implemented by other embodiments that do not depart from its spirit or essential features. Therefore, the embodiments disclosed above are, in all respects, merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are intended to be encompassed by the present invention.
