Description

Technical Field

[0001] The invention relates to the technical field of water environment management, and in particular to an integrated rainwater flower box. Background Art

If you want to reuse it, you need to design and equip a complete set of recycling systems under normal circumstances, such as water storage tanks, water pumps, pipes (above and below ground), valves and other facilities. Water that may come into direct contact with people also needs to be disinfected through disinfection treatment components, which greatly limits the widespread development of rainwater recycling.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The purpose of the present invention is to provide an integrated rainwater flower box to solve the problems existing in the prior art.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] This embodiment provides an integrated rainwater flower box, such as Figure 1 , Figure 2 As shown, it includes a rainwater treatment collection box 20 and a capillary planting bed box 21. The bottom of the rainwater treatment collection box 20 and the capillary planting bed box 21 are both provided with a base 22; a rainwater downpipe 1 is provided on one side of the rainwater treatment collection box 20, and the capillary planting bed box 21 is provided on the other side of the rainwater treatment collection box 20.

[0028] In the rainwater treatment collection box 20, there are a water retention layer 5, a vegetation planting filter medium layer 6, a transition layer 7 and a treatment water retention layer 8 distributed from top to bottom. A water distribution pipe 4 is arranged on the top of the vegetation planting filter medium layer 6. The rainwater downpipe 1 is connected to the water distribution pipe 4 through the diverter 2 and the water inlet pipe 3. When it rains, the rainwater in the rainwater downpipe 1 enters the system through the diverter 2 and the water inlet pipe 3, and enters the water distribution pipe 4. One end of the water distribution pipe 4 is connected to the rainwater downpipe 1 diverted into the water inlet pipe 3, and the other end is sealed, and the surface is evenly pore-opened. After the rainwater enters the system from the water distribution pipe 4, when the water inflow rate is greater than its downward infiltration rate, the rainwater gathers on the surface and is retained in the retention layer. The rainwater that penetrates downward is filtered and treated by the sandy loam in the vegetation planting filter medium layer 6, and continues to flow through the transition layer 7 composed of a mixture of fine, medium and coarse sand particles into the treatment water retention layer 8 covered with gravel, and is collected and stored.

[0029] In this embodiment, a water level regulating overflow pipe 10 is also included. One end of the water level regulating overflow pipe 10 is connected to the treated water retention layer 8, and the other end is connected to the building downpipe through the system outlet pipe 11, and the connection point is equal to or lower than the bottom height of the treated water retention layer 8; a water level regulating overflow pipe 10 is provided at one end of the bottom of the treated water retention layer 8, and the other end of the water level regulating overflow pipe 10 is connected to the building downpipe, and the connection point is horizontal or lower than the bottom height of the treated water retention layer 8. When the vertical pipe of the water level regulating overflow pipe 10 is rotated to 90 degrees with the ground, the pipe mouth height of the top horizontal pipe of the water level regulating overflow pipe 10 is flush with the top height of the treated water retention layer 8. When the vertical pipe of the water level regulating overflow pipe 10 is rotated to 0 degrees with the ground, the pipe mouth height of the water level regulating overflow pipe 10 is flush with the bottom end of the water retention layer. The water level regulating overflow pipe 10 is adjusted and controlled by rotating to control the water storage depth in the water retaining layer.

[0030] In this embodiment, a treatment perforated drain pipe 9 and a backwash pipe 12 are also provided in the rainwater treatment collection box 20. The treatment perforated drain pipe 9 is transversely arranged at the bottom of the treatment water-retaining layer 8. After the rainwater treated by the vegetation planting filter medium layer 6 enters the treatment water-retaining layer 8, it can enter the drain pipe from the holes on the treatment perforated drain pipe 9. When the rainwater continues to flow in and exceeds the overflow water level, it is smoothly discharged from the water level regulating overflow pipe 10 by the drainage pipe. The top of the backwash pipe 12 extends out of the aquifer 5, and the bottom is connected to the treatment perforated drain pipe 9. After the system has been running for a long time, the sand in the transition layer 7 gradually moves downward with the treatment water flow into the gravel between the treatment water-retaining layer, and may block the small holes on the treatment perforated drain pipe 9, reducing the drainage efficiency of the perforated drain pipe 9. At this time, a high-pressure water gun can be used to connect the backwash pipe 12, and the holes of the perforated drain pipe 9 at the bottom of the system can be cleaned by water pressure to ensure the unobstructed holes on the treatment perforated drain pipe 9 and improve the drainage efficiency.

[0031] In this embodiment, the bottom of the capillary planting bed box 21 is a capillary water-retaining layer 15, and the bottom end of the water-retaining layer 8 is connected to the capillary water-retaining layer 15 through a water level connecting pipe 13, and the water level is kept linked; a plurality of capillary perforated drainage pipes 14 are longitudinally arranged in the capillary water-retaining layer 15, and the plurality of capillary perforated drainage pipes 14 cover the bottom of the capillary planting bed box 21; a plurality of through holes are opened on the wall of the capillary perforated drainage pipe 14, and the top of the capillary water-retaining layer 15 is an air layer 16, and the capillary perforated drainage pipe 1 4 is the top of the air layer 16, and the top of the air layer 16 is higher than the top of the treated water-retaining layer 8; according to the principle of water level linkage, the water level of the capillary water-retaining layer 15 is the same as that of the treated water-retaining layer 8, both are lower than the highest point of the air layer 16, ensuring the existence of the air layer 16; the top of the air layer 16 is the capillary irrigation vegetation planting layer 18, and a capillary geotextile layer 17 is also arranged between the inner wall of the capillary planting bed box 21, the capillary perforated drainage pipe 14 and the capillary irrigation vegetation planting layer 18.

[0032] In this specific embodiment, gaps are provided between two adjacent capillary perforated drainage pipes 14 and between the capillary perforated drainage pipes 14 and the inner wall of the capillary planting bed box 21. The capillary geotextile layer 17 extends vertically downward from the top of the capillary planting bed box 21 along the inner wall of the box, and after reaching the bottom of the capillary water-retaining layer 15, it wraps the outer wall of the capillary perforated drainage pipe 14 near the edge upward, and after wrapping to the top of the pipe, it starts to move downward, and is laid along the gap to the lower end of the capillary water-retaining layer 15, and then turns upward to wrap the outer wall of the adjacent capillary perforated drainage pipe 14, and wraps all the outer walls of the capillary perforated drainage pipes 14 except for the contact with the bottom of the capillary water-retaining layer 15 in turn. This wrapping method ensures that the contact area between the capillary geotextile layer 17 and the medium in the capillary irrigation vegetation planting layer 18 is maximized, thereby enhancing the speed and efficiency of capillary irrigation.

[0033] The capillary irrigation vegetation planting layer 18 is located in the space surrounded by the capillary geotextile layer 17. The capillary phenomenon principle is used to transport the water in the capillary water retention layer 15 through the capillary geotextile layer 17 to all the medium soils in contact with it. With the help of the growth of vegetation, its roots continuously absorb moisture in the medium soil, so that a difference in moisture is formed between the drier soil around the roots and the more moist soil around the capillary geotextile layer 17, which prompts the water in the capillary water retention layer 15 to continuously move through the capillary geotextile layer 17 to the roots of the vegetation, and finally be absorbed and consumed by the vegetation, thereby achieving the optimization of the efficiency of rainwater recycling and reuse.

[0034] In this embodiment, a ventilation and water supply pipe 19 is also vertically arranged in the capillary planting bed box 21. The top of the ventilation and water supply pipe 19 extends out of the capillary irrigation vegetation planting layer 18 and is connected to the atmosphere, and the bottom of the water distribution pipe 4 is connected to the air layer 16. The ventilation and water supply pipe 19 is vertically set up in the capillary planting box 21, so that the air layer 16 inside the system is always connected to the external atmosphere, ensuring that the soil is in contact with air to avoid excessive waterlogging. In drought periods, the capillary water retention layer 15 can also be replenished with water through the pipe to prevent the vegetation from being affected by long-term drought.

[0035] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
