Technical Field

[0001] The invention relates to the technical field of garden irrigation, in particular to a circulating water supply device for garden greening. Background Art

[0002] Landscaping is the creation of a beautiful natural environment and recreational space in a certain area by using engineering technology and artistic means, through transforming the terrain, planting trees and flowers, constructing buildings and arranging garden paths. It is called a garden. Gardens include courtyards, residential gardens, small gardens, flower gardens, parks, botanical gardens, zoos, etc. With the development of gardening, it also includes forest parks, scenic spots, nature reserves or national park tourist areas, and rest resorts. In landscaping, water supply devices are used to irrigate vegetation. In order to reduce water waste, water supply devices will collect natural precipitation.

[0003] After searching, Chinese patent number CN217136296U discloses a circulating water supply device for gardening. Although it has the advantages of good collection and filtering effects, its collection range of natural precipitation is small, and the device body occupies a large area. At the same time, the water source for garden irrigation comes entirely from natural precipitation. When natural precipitation is insufficient, it is impossible to automatically start external water supply. If artificial auxiliary water supply is used, it is impossible to grasp the collection amount of natural precipitation from time to time manually, and it is necessary to observe the collection amount regularly, which reduces the degree of automation and cannot operate autonomously for a long time. The scope of the garden is generally large, and the use of the circulating water supply device is large. If the degree of automation is low, the manual work intensity is high, and it is not conducive to observing the collection amount of natural precipitation. In addition, the efficiency of the external water supply cannot be coordinated with the use efficiency of garden irrigation, which easily leads to insufficient water supply during irrigation and excessive water supply resulting in waste.

[0040] Specifically, during the installation of the circulating water supply device, the water inlet conduit 6 is connected to the external water supply pipe, and then the water collecting bucket 1, the collecting plate 2 and the filter screen 3 are pre-buried to the designated position, and the output conduit 5 is located above the ground. At this time, landscaping is carried out according to demand. During the above process, the circulating water supply device is completely located below the ground, so that the circulating water supply device occupies a very small area and does not affect the design and beauty of landscaping. When natural precipitation occurs, water falls to the ground and irrigates the landscaping vegetation. The water continues to infiltrate through the soil and finally passes through the filter screen 3 and falls into the collecting plate 2.

At the same time, it is also beneficial to the collection of water after artificial irrigation to avoid waste of water resources.

[0041] The working principle and use process of the present invention are as follows: before using the circulating water supply device, the water inlet conduit 6 is connected to the external water supply pipe, and then the water collecting bucket 1, the collecting plate 2 and the filter screen 3 are pre-buried to the designated position, and the output conduit 5 is located above the ground. At this time, landscaping is carried out according to demand. In the above process, the circulating water supply device is completely located below the ground, so that the circulating water supply device occupies a very small area and does not affect the design and beauty of landscaping. When natural precipitation occurs, water falls to the ground and irrigates the landscaping vegetation. The water continues to infiltrate through the soil and finally passes through the filter screen 3 and falls into the collecting plate 2. The collecting plate 2 is extremely wide, so that the circulating water supply device fully expands the collection range of natural precipitation without affecting the natural environment of the vegetation. At the same time, it is also beneficial to collect water after artificial irrigation to avoid waste of water resources.

[0042] When the landscaping needs artificial irrigation, the water pump 4 in the water collecting bucket 1 is started, so that the water pump 4 transfers the water in the water collecting bucket 1 to the output conduit 5 and completes the irrigation. If the liquid level in the water collecting bucket 1 is below the water inlet conduit 6, the water in the water collecting bucket 1 cannot meet the irrigation demand. At this time, the fixed nozzle 13 and the first air inlet pipe 12 are unblocked, so that the diaphragm 16 in the closed cylinder 14 is flat, so that the air pressure in the fixed rod 18 is constant, so that the first top block 21 is always separated from the through hole 9, so that the water in the external water supply pipe flows through The water flows into the top of the partition 7 through the through hole 9, so that the water flow squeezes the second top block 22, so that the second top block 22 is separated from the fixed block 8, and the support spring 23 is compressed, so that the water flow can further flow into the inner cavity 10 and the water collecting bucket 1, so that the water collecting bucket 1 can be continuously supplied with water. In the above process, when the water flows into the inner cavity 10, according to the Venturi effect, the fixed nozzle 13 absorbs air and flows into the inner cavity 10 through the first air inlet pipe 12 and the branch guide groove 11. When the liquid level in the water collecting bucket 1 is above the water inlet conduit 6, the fixed nozzle 13 blocks the water. Plug, at this time, the end of the branch guide groove 11 connected to the inner cavity 10 is in a negative pressure state, so that the second air inlet pipe 15 connected to the branch guide groove 11 absorbs the air at the top of the closed tube 14, so that the diaphragm 16 in the closed tube 14 is recessed upward, and then the diaphragm 16 absorbs the air in the fixed rod 18 through the connecting pipe 17, so that the air pressure at the upper end of the fixed rod 18 is reduced, so that the piston 19 in the fixed rod 18 rises under the action of atmospheric pressure, so that the piston 19 pulls the first top block 21 to rise through the telescopic rod 20, and then the first top block 21 blocks the through hole 9, so as to achieve the purpose of cutting off the water inlet conduit 6, increase the water source for garden irrigation, when natural precipitation is insufficient, the external water supply can be opened automatically, and no artificial auxiliary water supply is required. When the water collection amount in the water collection bucket 1 is large, the external water supply can be closed automatically, which not only improves the degree of automation of the device, but also can operate autonomously for a long time, can fully adapt to a wide range of garden use, and does not require the participation of electrical components, is suitable for the use environment of the device underground, and can reduce the probability of device damage and avoid maintenance of the underground device.

[0043] In the above process, if the external water supply and the irrigation of the garden are carried out at the same time, the pump shaft 33 in the water pump 4 can drive the active bevel gear 32 to rotate, so that the driven bevel gear 31 on the active bevel gear 32 drives the driven sprocket 29 to rotate through the transmission shaft 30, so that the chain belt 28 on the driven sprocket 29 drives the active sprocket 27 to rotate, so that the rotating shaft 25 on the active sprocket 27 rotates, so that the paddle 26 on the rotating shaft 25 rotates, and then the paddle 26 accelerates the movement of the water flow in the water inlet conduit 6. In the above process, the rotation speed of the pump shaft 33 is the same as the rotation speed of the rotating shaft 25, so that the efficiency of the external water supply and the use efficiency of the garden irrigation can be coordinated, avoiding the phenomenon of insufficient water supply during irrigation and excessive water supply causing waste, and completing the operation.
