Description

Green belt irrigation system under viaduct based on siphon drainage

technical field

The utility model belongs to the technical field of water resource reuse, in particular to an irrigation system for green belts under viaducts based on siphon drainage.

Background technique

With the continuous development of modern society and the acceleration of urbanization, the number of urban residents is increasing, and the urban traffic situation is becoming more and more congested. In order to meet the travel requirements of residents, urban traffic has gradually developed from the ground to the air, and the number of viaducts is increasing. more and more. At the same time, the status of urban greening is becoming more and more important, and the area of green belts in various cities is increasing. However, the irrigation method generally adopted in various places is manual watering, which not only has outdated equipment and low efficiency, but also wastes a lot of water resources.

According to the survey, 2/3 of the cities in my country are short of water, and more than 100 of them are seriously short of water, which has greatly affected the sustainable development of the economy and society. In addition, the unreasonable discharge of urban industrial and domestic sewage leads to pollution of water supply sources, making urban water resources more scarce. In this case, it is necessary to allocate a large amount of water resources to irrigate the green belts, which is a waste of resources. It is worth noting that the annual average rainfall of northern cities is 590mm, and that of southern cities is as much as 1340mm. If they can be used rationally, they can bring good ecological and environmental benefits and economic benefits to cities. Therefore, recycling urban rainwater is of great significance to the good development of cities and society.

Detailed ways

The utility model will be further described below in conjunction with the embodiments and the accompanying drawings.

See Fig. 1, the utility model system comprises rainwater collection unit, intelligent control unit and irrigation unit. The rainwater collection unit includes a siphon rainwater bucket 1 and a water storage container 4. The siphon rainwater bucket 1 is equidistantly distributed on both sides of the bridge deck of the viaduct. The siphon rainwater bucket 1 has its own grille, which can intercept floating objects in the rainwater to prevent blockage. The water storage container 4 is arranged on the pier under the bridge deck of the viaduct, and a screen 6 is arranged in the water storage container 4 to filter out suspended matter such as fiber and paper pulp in the rainwater, so as to avoid blocking the wetting pipe 5b. The siphon rainwater bucket 1 introduces rainwater into the water storage container 4 through the connecting pipe 2 . In this specific embodiment, the connecting pipe 2 is a PVC pipe.

The intelligent control unit comprises a water level sensor 3, an A/D converter, a single-chip microcomputer and an indicator light, and the water level sensor 3, the A/D converter, the single-chip microcomputer, and the indicator light are connected in sequence. The water level sensor 3 is arranged in the water storage container 4, and is used to collect the water storage level information in the water storage container 4, and sends the collected water storage water level information to the A/D converter for digital-to-analog conversion. The water level information is sent to the single-chip microcomputer, and the single-chip microcomputer controls the indicator light according to the water storage level information. The A/D converter and the single-chip microcomputer are arranged under the deck of the viaduct, and the indicator lights are arranged on the guardrail of the viaduct. In this specific embodiment, the A/D converter adopts the ADC0809 type A/D converter, and the single-chip microcomputer adopts the 80C51 general-purpose single-chip microcomputer.

The irrigation unit includes a micro-moisture pipe 5b, and a pipe 5a is used to communicate the water storage container 4 with the micro-moisture pipe 5b. One end of the pipe 5a is connected to the water outlet at the bottom of the water storage container 4, and the other end is connected to the water inlet of the micro-moisture pipe 5b. The micro-moisture tube 5b is buried underground, and the burial depth is determined according to the depth of the main root layer of the crop. In this specific implementation, the burial depth of the micro-moisture tube 5b is 10cm-20cm. The micro-run tube is a hose-shaped water feeder made of a semi-permeable membrane as the core material. It has a double-layer structure. The tube wall is provided with holes with a fixed hole distance. The number is more than 100,000 per square centimeter, and the pore diameter of the micropore is 10nm to 900nm. The micropore allows water molecules to pass through but does not allow larger molecular groups and solid particles to pass through. When the micro-moisture tube is filled with water, the water molecules migrate outward through the micropores. Since the micro-moisture tube is buried deeper than the soil, the water further migrates to the soil, making the soil moist and playing the role of irrigation.

Preferably, the water storage container 4 is also connected to a drainpipe, and when the rainfall is sufficient, excess water stored in the water storage container 4 flows to the existing drainage pipe network through the drainpipe. The drain pipe is also provided with a one-way valve to prevent backflow of water in the drain pipe network.

The working process and working principle of the present utility model will be described in detail below.

When rainfall occurs, the rainwater on the bridge deck automatically collects into the siphon rainwater bucket 1 due to gravity, and enters the connecting pipe 2 through the siphon rainwater bucket 1, and then converges to the water storage container 4. The water stored in the water storage container 4 flows into the wetting pipe 5b through the pipeline 5a due to its own gravity. The water level sensor 3 is used to collect water level information in the water storage container 4. The water level information collected by the water level sensor 3 is a digital signal, which is converted into an analog signal by an A/D converter and then sent to the microcontroller. When the rainfall is sufficient, the water storage container 4 can be filled with water, the single-chip microcomputer receives the signal of the water level sensor 3, and the indicator light is turned green, indicating that the water in the container is sufficient, and there is no need to manually add water, and the excess water can flow along the original drainage pipe Normal drainage network. When there is no rainfall for a long time, the water storage capacity of the green belt is large, and the water level in the water tank is lower than the water level required for irrigation, the single-chip microcomputer receives the signal of the water level sensor, and the indicator light turns red to remind the relevant green belt staff to pass the siphon rainwater in time. The water is replenished in the water storage container, which effectively reduces the workload of the gardeners and fully improves the utilization rate of water resources.

The utility model has no other energy-consuming modules except the intelligent control unit, and therefore does not need a special energy source. The water level sensor, A/D converter, single-chip microcomputer and indicator light in the intelligent control unit can be connected to the adjacent street lamp circuit.
