In order to ensure that rainwater flowing in from the first through holes 1-6 can smoothly flow into the bottom cavity, the bottom of the sealing plate 1-11 is provided with second through holes 1-9, and when the sealing plate 1-11 is closed, the second through holes are positioned below the first through holes to prevent water from flowing out from the baffle device 1-7. The limiting device further comprises two L-shaped baffle strips 1-10 which are symmetrically distributed on two sides of the first water through holes 1-6.
Referring to fig. 1, each pipeline structure of the green belt maintenance system is also shown, wherein the second rainwater pipe comprises a straight pipe 6, a straight pipe valve 13, a three-way pipe, a bottom cavity valve 9 and a drainage valve 12. The straight pipe 6 is communicated with the bottom of the water collecting barrel 2, and the straight pipe valve 13 is used for controlling the water passing state of the straight pipe valve 13; the top of the three-way pipe is communicated with the bottom of the straight pipe 6, the left end of the three-way pipe is communicated with the bottom cavity structure 1-1 through a bottom cavity pipe 10, and the right end of the three-way pipe is communicated with a first drainage pipe 11; the bottom cavity valve 9 is used for controlling the communication state between the bottom cavity structure 1-1 and the second rainwater pipe; and a drain valve 12 for controlling a drain state of the second rainwater pipe. The top of the water collecting barrel 2 is provided with an air pressure port 7 for adjusting the air pressure in the water collecting barrel 2, and the air pressure port 7 is mainly used for exhausting air in the water collecting barrel 2, so that rainwater collected by the rainwater hopper 3 can smoothly flow into the water collecting barrel 2; the opening of the air pressure port 7 is in threaded connection with an air pressure cover. The water collecting barrel 2 further comprises a second water discharging pipe 5 and a tap water pipe 8, a water inlet of the second water discharging pipe 5 is located at a warning water level of the water collecting barrel 2, the warning water level is arranged between the upper portion and the top surface of the water collecting barrel 2, and a water discharging port of the second water discharging pipe 5 is communicated with a municipal sewer; the water outlet of the tap water pipe 8 is communicated with the water collecting barrel 2.
This greenbelt maintenance system can deal with three kinds of different climatic conditions:
when the rainfall is small, rainwater penetrates through soil 1-8 of the lawn on one hand and then enters the lower half part of the nursery stock box 1-5 through the hollow of the filter screen structure 1-4 to be stored, and when the water surface of the lower half part of the nursery stock box 1-5 rises to the height of the first water through hole 1-6, rainwater flows into the bottom cavity structure 1-1 through the water through device 1-2 to be stored again; on the other hand, the rainwater can flow into the water collecting bucket 2 through the rainwater hopper 3 through the first rainwater pipe 4 to be stored.
When the weather is clear, if the lawn planted in the nursery stock box 1-5 needs to be replenished with water, only the straight pipe valve 13 and the bottom cavity valve 9 need to be opened, because the height of the water collecting barrel 2 is higher than that of the maintenance box 1, and the volume of the water collecting barrel 2 is far larger than that of the maintenance box 1, water flow can enter the bottom cavity structure 1-1 through the straight pipe 6 and the bottom cavity pipe 10 of the three-way pipe, at the moment, the water level of the bottom cavity structure 1-1 rises continuously, the water flow can enter the water passing device 1-2, the sealing plate 1-11 is lifted under the action of the water pressure in the water passing device 1-2, and the first water passing hole 1-6 is sealed; then, water flow reaches the interior of the drip irrigation pipe 1-3 through the water passing device 1-2 and finally flows out of a drip pipe opening in the drip irrigation pipe 1-3, so that water is supplemented to the lawn; with the water supplement, the water can sequentially pass through the soil 1-8 and the filter screen structure 1-4 to reach the lower part of the nursery stock box 1-5 for storage. After the water replenishing of the lawn is finished, the straight pipe valve 13 is closed, the drainage valve 12 is opened, the water remained in the straight pipe 6, the bottom cavity structure 1-1 and the water passing device 1-2 is drained into a municipal sewer through the first drainage pipe 11, meanwhile, as the interior of the water passing device 1-2 is emptied, the sealing plate 1-11 falls under the action of self gravity and is blocked by the L-shaped stop strip 1-10, the first water passing hole 1-6 is opened, and the excessive water accumulated in the nursery stock box 1-5 is drained into the bottom cavity structure 1-1 through the first water passing hole 1-6, so that the water level in the nursery stock box 1-5 is kept at a safe height, and the situation that the soil 1-8 has excessive water to cause root rot is avoided. The L-shaped blocking strips 1-10 are used for preventing the sealing plates 1-11 from completely falling and are parallel to the inner side walls of the water passing devices 1-2, the L-shaped blocking strips 1-10 can enable the inner side walls of the water passing devices 1-2 of the sealing plates 1-11 to be at a certain angle, when water flows gush into the water passing structures from the bottom cavity structures 1-1, the sealing plates 1-11 can have certain contact surfaces with the water flows, and the sealing plates 1-11 can be rapidly lifted to seal the first water passing holes 1-6. If the water storage capacity in the water collecting barrel 2 is insufficient, only the tap water pipe 8 needs to be opened, and water can be supplemented into the water collecting barrel 2. Meanwhile, when the pesticide is required to be sprayed to the lawn, the pesticide is thrown into the water collecting barrel 2 only through the air pressure port 7, after the pesticide is fully mixed with water in the water collecting barrel 2, the straight pipe valve 13 and the bottom cavity valve 9 are only required to be opened, and the step of replenishing water to the lawn planted in the nursery stock boxes 1-5 is repeated, so that the function of spraying the pesticide to the lawn can be achieved, and the spraying efficiency is very high.
When the rainfall is large and exceeds the warning water level of the water collecting barrel 2, the second drain pipe 5 positioned at the warning water level starts to drain water, the water in the water collecting barrel 2 is mainly drained in the process, and the second drain pipe 5 is not controlled by a valve and automatically drains water under the influence of the water storage amount; meanwhile, in order to prevent water from being stored on the roof, the normal drainage function of the rainwater hopper 3 is ensured, so that the pipe diameter of the second drainage pipe 5 is larger than or equal to that of the first rainwater pipe 4, and the normal rainwater drainage quantity is realized. On the other hand, due to the excessive rainfall, in order to prevent the soil 1-8 and the lawn from being damaged by the overflowing water due to the overflowing water in the maintenance box 1, the straight pipe valve 13 needs to be closed, and the bottom cavity valve 9 and the drainage valve 12 need to be opened at the same time, at this time, the first drainage pipe 11 continuously drains the water in the maintenance box 1, and the soil 1-8 and the lawn are protected from being damaged by the rainwater.
The above description is only exemplary of the present invention, and not intended to limit the present invention, and any modifications, equivalents, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
Other technical features than those described in the specification are known to those skilled in the art, and are not described in detail herein in order to highlight the novel features of the present invention.
