The Design And Installation of The Automatic Irrigation System for Villa Family Gardening

The Design and Installation of the Automatic Irrigation System for Villa Family Gardening requires comprehensive consideration of plant needs, environmental conditions, intelligent management, and landscape coordination. The following is a comprehensive design scheme and application suggestions based on the search results:

I. Design Key Points and Basis

Precise Irrigation Matching Plant Needs

- According to the differences in water requirements of different plant types (such as lawns, shrubs, and flowers), a zoned and timed irrigation strategy is adopted. For example, in a villa case in Chongqing, the water requirement of the lawn is 6.5mm per day, and that of the shrubs is 8.3mm per day, which is calculated based on the plant coefficient (Kc) and the evaporation rate (ETo).

- The soil type affects the irrigation frequency: sandy loam has poor water retention, so the irrigation interval needs to be shortened (for example, the lawn is irrigated once every 1-2 days, and the shrubs are irrigated once every 2-3 days).

Environmental Adaptability Design

- Adjust the system parameters according to the climatic characteristics. For example, in the hot summer in Chongqing, the design needs to consider the evaporation rate (9.5mm per day) and the cooling demand under extreme climatic conditions. Combined with spray nozzles, a microclimate is created to reduce the local temperature.

- Anti-freezing design: In northern regions, a drain valve needs to be installed, and the pipeline should be emptied in winter to prevent it from cracking due to freezing.

Concealment and Landscape Integration

- The equipment needs to be installed in a concealed way, such as buried sprinklers and pre-buried pipelines (buried at a depth of 15-20cm) to maintain the integrity of the landscape during the non-irrigation period.

- Use water feature nozzles or atomization effects to form a dynamic landscape decoration during irrigation.

II. Selection and Layout of Core Equipment

Irrigation Equipment

- Sprinkler Type: For small lawns (<100㎡), scattering sprinklers are selected; for large areas (>100㎡), rotary gear sprinklers are used, and the coverage radius can reach up to 20 meters.

- Drip Irrigation and Micro-spraying: Drip irrigation (water-saving and quiet) is adopted in flower pots or densely vegetated areas, and micro-spraying (even coverage) is used in shrub areas.

- Pipeline Material Selection: PVC or PPR pipes are recommended for the main pipeline, and PE pipes are used for the branch pipes, which are corrosion-resistant and easy to construct.

Intelligent Control System

- Controller: It supports preset programs and remote control (such as the Rain Bird system), and is compatible with rainfall sensors and soil moisture sensors to achieve fully automatic management.

- Internet of Things Integration: Remote monitoring of irrigation, fertilization, lighting, etc. can be realized through a mobile phone APP, such as the integrated water and fertilizer equipment of Jinye Technology or the intelligent courtyard system of Sumelun.

Water Source and Filtration System

- When directly connected to the tap water, a pressure regulating valve needs to be configured; when using lake water or well water, a water pump (such as a submersible pump) and a filtration system (mesh or disc filtration) need to be installed to prevent impurities from blocking the pipeline.

- The integrated pump house of "Nongtaitou Cloud Head" is recommended, which does not require approval, is movable, and integrates functions such as filtration, fertilization, and control.

III. Installation Steps and Precautions

Planning and Measurement

- Measure the size of the courtyard (assisted by a CAD drawing), divide the irrigation areas, and determine the location of the water source.

- Design the pipeline route and reserve inspection ports and water intake valves.

Pipeline and Equipment Installation

- The main pipeline is led out from the water source, and solenoid valves (a 1-inch valve is recommended, with a flow rate of 4m³/h) are installed in the branches to control each area.

- The sprinklers are arranged at intervals according to the coverage radius (for example, the distance between sprinklers = the spraying radius) to ensure there are no blind spots.

Debugging and Maintenance

- Test the water pressure and the coverage range of the sprinklers, and adjust the spraying angle and time (sprinkler irrigation for 10 minutes each time, drip irrigation for 30-60 minutes each time).

- Regularly clean the filter, empty the pipeline in winter, and check the operation status of the solenoid valves and the controller.

IV. Extended Functions of Intelligent Management

Multi-system Integration

- The intelligent courtyard solution can integrate irrigation, lighting, fish pond monitoring, and fogging systems, and manage them remotely through a single platform.

- Linkage with the weather station: Adjust the irrigation plan according to the real-ti
