Description

Liquid storage irrigation system

The present invention relates to an irrigation facility, and more particularly to a liquid storage irrigation system capable of storing water under the soil and utilizing the capillary action of the soil to supply water.

As the Earth warms, the frequency of extreme weather is becoming more frequent, and people in many areas are not attacked by heavy rains and droughts. In the event of heavy rain, urban jungles made up of cement buildings often cannot absorb large amounts of rainfall for a short period of time. Rainwater can only enter the sewers after surface runoff, resulting in flooding caused by the drainage system, and when the drought period is too long. The reservoir will face the problem of shortage of irrigation water. Therefore, how to transform the cement city into a sponge city, so that the city can absorb heavy rain like a jungle, and store water to face possible drought and reduce the impact of extreme weather is a problem that human life cannot escape in the future.

It is an object of the present invention to provide a liquid storage irrigation system that overcomes at least one of the disadvantages of the prior art.

The liquid storage irrigation system is suitable for accommodating a substrate and storing a liquid, and can be irrigated with the liquid. The liquid storage irrigation system includes a base unit and a network management unit.

The base unit is impervious to water and includes a base wall and a surrounding wall extending upwardly from the base wall to define a containment space in cooperation with the base wall. The network management unit is located at the bottom of the containment space, and partitions the containment space from a liquid storage area located inside the liquid to store the liquid, and a planting area above the liquid storage area for the planting substrate . The network management unit defines a plurality of cells that can supply water into and out of the liquid storage area and the planting area.

The effect of the liquid storage irrigation system is that the mesh of the network management unit can supply liquid freely in and out, so the liquid storage area defined by the network management unit can be used to store the rainwater to reduce the load of the drainage system during rainfall. When no rain falls, the rainwater stored in the network management unit can adjust the ambient temperature and irrigate the plants planted on the planting substrate to achieve various environmental protection effects such as flood detention, cooling, and water saving.

Referring to Figures 1, 2 and 3, an embodiment of the liquid storage irrigation system of the present invention is suitable for accommodating a seed substrate 11 and storing a liquid 12, and irrigating the plant planted on the plant substrate 11 with the liquid 12 .

Each of the network management groups 41 has a plurality of rectangular network tubes 42 arranged side by side and extending side by side and extending forward and backward on the gravel layer unit 3 and having a rectangular cross section. Each of the rectangular mesh tubes 42 includes a rectangular net body 421 having a rectangular cross section, and a rectangular rib 422 extending spirally and connected to the rectangular net body 421. Each rectangular mesh body 421 cooperates with the corresponding rectangular rib 422 to partition the receiving space 213 from a liquid storage channel 423, and each rectangular mesh body 421 further defines a plurality of meshes communicating with the liquid storage channel 423. 424. The reservoir channels 423 cooperate to form a reservoir 425 that can be used to store the liquid 12. The network management unit 4 also partitions the containment space 213 into a planting area 214 located above the liquid storage area 425 and communicating with the liquid storage area 425 through the meshes 424. The planting area 214 is provided for the planting substrate 11.

Referring to Figures 2, 3 and Figures 5 and 6, the liquid inlet unit 5 includes an infiltration mesh tube 51 disposed on the gravel layer unit 3 and extending forward and backward, and a space in the receiving space 213 and inserted into the planting substrate 11 And a liquid inlet pipe 52 communicating with the permeate network pipe 51. The permeating mesh pipe 51 has a bottom pipe wall 511 which abuts the gravel layer unit 3 and allows the liquid 12 to enter and exit, and a half pipe wall 512 which is curvedly connected downwardly to the left and right sides of the bottom pipe wall 511. The half pipe wall 512 is impervious to water and cooperates with the bottom pipe wall 511 to define a liquid inlet passage 513 having a semicircular cross section. The liquid inlet passage 513 can communicate with the gravel unit 3 through the bottom pipe wall 511 to allow the liquid 12 to enter or exit therefrom. The bottom end portion of the liquid inlet tube 52 communicates with the top end portion of the permeate mesh tube 51, and the tip end portion thereof protrudes upwardly from the planting substrate 11 to be filled into the liquid 12, and the liquid 12 flows from the outside. In the liquid inlet channel 513.

The non-woven unit 6 is located between the network management unit 4 and the planting substrate 11 to prevent the soil in the planting substrate 11 from falling into the liquid storage area 425 and occupying the space of the liquid storage area 425, thereby causing the liquid storage. The amount of liquid stored in zone 425 is reduced.

The overflow tube 7 includes a cannula 71 extending laterally extending on the surrounding wall 212 of the housing seat 21, an L-shaped transfer tube 72, and an up-and-down extension inserted in the transfer The liquid tube 73 on the tube 72. The cannula 71 has a liquid inlet 711 that communicates with the housing space 213 of the housing seat 21. The liquid inlet 711 is lower than the top of the network management unit 4. The transfer tube 72 is connected between the cannula 71 and the liquid tube 73, and is sleeved outside the cannula 71 and the liquid tube 73, and is pivotable relative to the cannula 71. The liquid pipe 73 has a liquid outlet 731 that communicates with the outside. The liquid outlet 731 is lower than the top of the network tube unit 4. The overflow pipe 7 is discharged from the liquid outlet 731 after the liquid 12 located in the liquid storage zone 425 overflows, and the height of the liquid outlet 731 is variably adjustable.

Referring to Figures 2, 3 and 7, at the time of rainfall, the liquid 12 composed of rainwater will penetrate into the planting substrate 11 and move downward through the nonwoven unit 6 and through the network tube unit as shown in Figure 4. The cells 424 of 4 enter the reservoir 425 and are stored in the reservoir 425. The liquid storage area 425 can store the design of the liquid 12, and can effectively absorb rain water when it is raining, and avoid the rainwater path from flowing into the drainage system such as the sewer, and can have the effect of flood detention and flood detention.

The height of the liquid inlet 711 and the liquid outlet 731 of the overflow pipe 7 is lower than the design of the top end of the network tube unit 4, so that the excess liquid 12 overflows out of the embodiment to avoid the liquid 12 being completely occupied. All of the reservoir area 425 is formed with an air layer 426 at the top end of the reservoir area 425. The air layer 426 provides the space required for plant roots to rot and avoids plant root decay.

When there is no rainfall, the liquid 12 located in the liquid storage zone 425 will gradually volatilize or move to the side to be in contact with the planting substrate 11 located at the center, and under capillary action, in the planting substrate 11 It moves autonomously to the roots of plants and is absorbed by the roots of plants, producing the effect of autonomous irrigation. Since rainwater stored during rainfall can be used instead of tap water for irrigation, the present embodiment can reduce the amount of tap water used.

If the time of no rain is too long, the liquid 12 in the liquid storage area 425 is too small, and the user can pour the liquid 12 of tap water or the like from the top opening of the liquid inlet tube 52 as shown in FIG. After the liquid 12 enters the permeate network tube 51, it flows into the gravel unit 3 from the bottom tube wall 511 of the permeate network tube 51. The liquid 12 can move left and right in the gravel unit 3 and penetrate into the liquid storage passage 423 of each rectangular mesh tube 42 through the mesh openings 424 of each rectangular mesh tube 42. That is, the user can automatically fill the liquid storage area 425 by simply filling the liquid 12 into the liquid inlet tube 52. Since the liquid 12 can also be a fertilizer water as described above, it is also possible to provide liquid fertilizer water in this manner.

In contrast to the irrigation mode in which the liquid 12 is directly sprinkled on the planting substrate 11, the aforementioned liquid 12 is poured into the inlet pipe 52 for storage in the autonomous irrigation mode of the liquid storage zone 425, since the liquid 12 is from bottom to top. The ground is directly in contact with the plant roots, and can effectively absorb the roots of the plants, and avoids many liquids 12 being exposed to the sun and volatilizing from the surface of the planting substrate 11, so that irrigation can be more efficiently. In addition to the advantage of being able to reduce the amount of tap water used by rainwater, this embodiment has the advantage of improving irrigation efficiency.

Referring to Figures 8 and 9, the present embodiment, when in use, may be placed beside a building as shown in Figure 8, or on the roof of a building as shown in Figure 9. The advantage of being placed next to the building is that the user can easily take care of the planted plants, and the present embodiment can be easily operated, and the plants planted can be used for pedestrians to watch, green and beautify the city, change the residents' perception of the city, and enhance the residents and the city. feeling. When the present embodiment is placed next to a building, it can be further operated in conjunction with a drainage system 8 of the building. The drainage system 8 includes a sump 81 extending horizontally for receiving roof rainwater, a drain pipe 82 extending downward from the sump 81, a control valve 83 disposed intermediate the drain pipe 82, and a control valve 83 The control valve 83 extends obliquely down to the water injection pipe 84 at the top end of the liquid inlet pipe 52 of the liquid inlet unit 5. Rainwater may be concentrated into the drain pipe 82 during rainfall, and the control valve 83 may be electrically or manually driven to determine whether rainwater is discharged from the drain pipe 82 or injected through the water injection pipe 84. The liquid inlet pipe 52 is replenished into the present embodiment to increase the amount of rainwater collected in the present embodiment.

When the present embodiment is installed on a roof, in addition to being able to free up a plane space for parking, the concept of a green roof and a blue roof can be exerted. The green roof refers to the problem that the cement roof is easily heated by the sun through the shielding provided by the planted plants, thereby effectively reducing the indoor temperature rise and reducing the air conditioner usage to reduce the power consumption. The blue roof refers to the liquid 12 located in the liquid storage area 425, and can adjust the ambient temperature as a heat storage like the ocean, and can also prevent the roof from rapidly heating up due to the sun, and reduce the usage and consumption of the air conditioner. Electricity.

Referring to Figures 3 and 10, in this embodiment, the transfer tube 72 can be pivoted during use to change the height of the liquid outlet 731 of the liquid tube 73. For example, the transfer tube 72 in FIG. 4 can be pivoted from top to bottom by 180 degrees, so that the liquid outlet 731 of the liquid tube 73 faces downward, so that the position of the liquid outlet 731 can be lowered to make it located. The liquid level in the reservoir zone 425 drops. The benefit of this design is that it allows the user to adjust the level of the liquid 12 depending on the environment of use or different plantings. For example, when the present embodiment is disposed on a roof, considering the material and the weight resistance of the roof, the liquid outlet 731 can be adjusted to adjust the liquid storage amount of the liquid storage area 425 to control the overall weight of the embodiment. the goal of. In other embodiments of the present invention, the overflow tube 7 may also be integrally L-shaped and pivotally inserted at one end thereof on the housing seat 21.

In summary, the effect of the liquid storage irrigation system of the present invention is that the liquid storage area 425 defined by the network management unit 4 can store rainwater, and has the advantages of reducing the use of tap water in addition to the advantages of reducing the surface runoff. Moreover, the irrigation efficiency of the autonomous irrigation method of the present invention is also higher than that of the conventional irrigation method. In addition, according to the location of the installation, the present invention can also produce an effect of improving the quality of life such as environmental greening or adjusting the ambient temperature.
