Below in conjunction with embodiment and accompanying drawing, the utility model is further described.

Example 1

A plant irrigation system based on building roof siphon drainage, including a plurality of siphon rainwater buckets 1 distributed on the building roof, and a plurality of siphon rainwater buckets 1 are connected to the first drainage pipe arranged on the building wall close to the irrigation green belt through the connecting pipe 2 3 connected, the bottom of the first drainage pipe 3 is connected to the top of the light water storage container 6 installed and fixed on the building wall; the water level sensor 9 is installed at the bottom of the light water storage container 6, and the water level sensor 9 is electrically connected with the single-chip electromechanical device, and the single-chip microcomputer is arranged on It is fixed in the equipment box 10 on the outer wall of the lightweight water storage container 6; the button module is electrically connected with the single-chip electromechanical device, and is used to input the set water level to the single-chip microcomputer, and the set water level is the water level required for irrigation; the outer wall of the lightweight water storage container 6 is installed with two Indicator lights 7 of different colors, indicator light A and indicator light B, the indicator lights are connected with the single-chip electromechanical, the lightweight water storage container 6 is connected with the water replenishment pipe 5 with the solenoid valve 4, the water replenishment pipe 5 is connected with the tap water pipe of the building, and the electromagnetic The valve 4 is connected with the single-chip electromechanical; the bottom of the lightweight water storage container 6 is connected with the second drainage pipe 12, and the second drainage pipe 12 is connected with the micro-moisture pipe 13 buried in the soil of the irrigation green belt; the system also includes a power supply for Supply power to single-chip microcomputer, solenoid valve, water level sensor, indicator light and button module.

The connecting pipe 2, the first drain pipe 3 and the second drain pipe 12 are all PVC pipes. The siphon rainwater bucket 1 has its own grille, and the middle part of the lightweight water storage container 6 is provided with a layer of screen 8, and the screen aperture is smaller than the aperture of the siphon rainwater bucket's own grid. The lightweight water storage container 6 is fixed by a stainless steel support frame installed on the building wall. A one-way valve 11 is installed on the second drainage pipe 12 to prevent water from flowing backwards. The color of indicator light A is preferably red, and the color of indicator light B is preferably green.

When the water level is lower than the set water level, the solenoid valve opens and the indicator light A lights up.

When the water level is higher than or equal to the set water level, the solenoid valve is closed and the indicator light B is on.

The irrigation system based on building roof siphon drainage mainly includes rainwater collection module, intelligent control module and irrigation module. When rainfall occurs, the roof rainwater will automatically collect to the siphon rainwater bucket of the rainwater collection module due to the action of gravity. , mechanical equipment and other devices, since the siphon drainage system technology is a very mature technology in the existing technology, I will not repeat it here; As a preference, the size of the water storage container is determined according to the amount of water required by the green belt near the building; a water level sensor and a screen are arranged in the lightweight water storage container, and the screen mesh is relatively small, mainly used to filter out rainwater Fiber, pulp and other fine suspended matter, so that it will not block the micro-moisture tube.

The water level sensor is mainly used to maintain the water level in the lightweight water storage container. When the rainfall is sufficient, the single-chip microcomputer receives the measured water level signal from the water level sensor, and compares the measured water level with the set water level. When the measured water level is higher than or equal to the set water level When the water level is reached, the command indicator light B is on, indicating that there is sufficient water in the container, and there is no need to replenish tap water. The excess water can flow along the original drainage pipe to the normal drainage pipe network. Valve to prevent abnormal backflow; when there is no rainfall for a long time and the water storage capacity of the green belt is large, the single-chip microcomputer receives the measured water level signal from the water level sensor and compares the measured water level with the set water level. When the measured water level is lower than the set water level , the command indicator light A is on, and the solenoid valve connected to the tap water pipeline is instructed to open at the same time, and the tap water is used as a supplementary water source. This method effectively reduces the workload of the gardening staff and fully improves the utilization rate of water resources.

The irrigation module is mainly micro-moist irrigation, which is mainly realized through underground micro-moisture pipes. The underground micro-moisture pipe utilizes the existing technology, which is a hose-shaped water feeder made of a semi-permeable membrane as the core material, and its buried depth is generally 10-20cm, depending on the depth of the main root layer of different crops; It has a double-layer structure, and its characteristic is that there are no holes with a fixed hole distance on the wall of the hose, and each point on the inner wall has a huge number of micropores; the number of holes is more than 100,000 per square centimeter, and the diameter of the micropores is 10-900 nanometers, the pore size distribution is within the scale of the semi-permeable membrane and has the characteristics of a semi-permeable membrane. The size of the pores on the membrane wall of the micro-wet tube allows water molecules to pass through but does not allow larger molecular groups and solid particles to pass through. When the tube is filled with water When the water molecules migrate to the outside of the pipe wall through these micropores, if the pipe is buried in the soil, the water will further migrate to the soil to make the soil moist and play an irrigation role. The water outlets are connected, and the pipelines located above the ground are all ordinary water delivery pipelines, while the pipelines located below the ground and in the root distribution soil are micro-moisture pipes. Since the lightweight water storage container is located at a certain height above the ground, it can provide the water head required for irrigation of the micro-running pipe, and there is no need for additional energy consumption to purchase a water pump, which is economical and practical.

The system has no other energy-consuming modules except the intelligent control module, so it does not need a special energy source. It is only necessary to connect the sensor, single-chip microcomputer and indicator light to the adjacent street lamp circuit.
