Description

Technical Field

[0001] The invention relates to a method for preparing a moisturizing system for ecological roof greening, in particular to a method for using a moisturizing system for preparing rainwater and tap water for greening on a roof. Background Art

[0002] At present, in order to make the environmental conditions close to the original natural ecological background and hydrological characteristics, many cities in my country have green roofs. Since the soil of the rooftop green pool needs to be continuously moisturized, it is mainly watered directly by hand. However, manual watering is time-consuming and laborious, especially during high temperature periods. Since the high temperature water evaporates quickly, watering is required one to several times a day. During holidays or personnel adjustments, the phenomenon of green plants dying due to untimely watering often occurs; however, direct manual watering uses a large amount of drinking water, which increases construction costs and energy consumption; due to the dry climate in winter or the long sunshine time and high temperature in summer, when the soil of the green pool is dry and needs to be watered, once the water supply system fails, the soil of the green pool cannot be watered in time, causing the plants to die, and the planting risk is extremely high; the water consumption of tap water irrigation during plant growth is large, and the rainwater when the rainfall is large is discharged through the sewer pipe and cannot be retained, so the problem of urban roof greening irrigation is difficult to solve; in view of the above reasons, a method for using a rooftop greening rainwater and tap water mixing and moisturizing system is proposed. Summary of the invention

[0003] The purpose of the present invention is to overcome the problem that when the soil of the greening pool is dry and needs to be watered in the winter or the summer when the sunshine time is long and the temperature is high, once the water supply system fails, the soil of the greening pool cannot be watered in time, causing the plants to wither and die, and the planting risk is extremely high; the water consumption of tap water for watering during plant growth is large, and the rainwater when the rainfall is large is discharged through the sewer pipe and cannot be retained, and the problem of watering urban roof greening is difficult to solve; now, through reasonable design, a method for using a system for mixing and moisturizing rainwater and tap water for greening on a roof is provided; the system for mixing and moisturizing rainwater and tap water for greening on a roof of the present invention can collect and store rainwater in the rainy season When the weather is dry, the collected rainwater is used to irrigate the green flowers and plants in the green flower pool. When the weather is dry for a long time and there is no rain, the greening water is supplemented by tap water. A large amount of tap water can be saved by irrigating the greening with the collected rainwater. When the weather is dry, the present invention controls the micro water pump through the sensor signal module and the drip irrigation center module of the drip irrigation control box, which can automatically irrigate the flowers and plants in the greening pool, thereby reducing manual watering. The purified water or tap water supplied to the water pool through rainwater purification can ensure that the green flowers and plants in the flower pool grow luxuriantly without the phenomenon of plant withering. It ensures that the flowers and plants in the greening pool have stable living conditions, thereby ensuring the normal greening of the ecological roof.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a method for using a system for mixing and moisturizing rainwater and tap water for greening on a roof; the system for mixing and moisturizing rainwater and tap water for greening on a roof is composed of a green flower pool, a rainwater collection and filtering cover, a rainwater collection pool, a rainwater purification water supply pool, a one-way valve filtering water inlet, a roof, an insulation layer, a water supply pool bottom insulation layer, a drain, a tap water pipe, a roof water retaining slope, a rainwater collection trough, a rainwater filtering material, a green flower pool drip pipe, a drip irrigation branch pipe, a micro water pump, a water supply float valve, a drip irrigation control box, a sensor signal module, a drip irrigation center module, and a soil moisture sensor.

[0005] A rainwater collection trough is arranged below the cross-shaped passage, and rainwater collection and filtering covers are arranged above the rainwater collection troughs. The bottom of the cross-shaped rainwater collection trough between the rainwater inlet end and the rainwater collection pool is arranged in a slope shape, and rainwater filtering materials are arranged between the rainwater collection trough and the rainwater collection pools; a pair of rooftop water retaining slopes are arranged on both sides of the greening module in the middle of the roof; the pair of rooftop water retaining slopes are arranged horizontally corresponding to the lower end of the rainwater collection trough; the left ends of the roof are arranged in a slope shape toward the center; the left, middle and right parts of the roof are arranged as upper, middle and lower sections of rainwater collection, and the water flow directions of the three sections of rainwater collection are arranged corresponding to the cross-shaped passage openings;

[0007] A drip irrigation control box is arranged on one side of the green flower pond, and a sensor signal module and a drip irrigation center module are arranged in the drip irrigation control box respectively.

[0009] When it rains in the rainy season, rainwater falling from the roof enters the cross-shaped channel from four directions. After entering, the rainwater is filtered through the rainwater collection filter cover and enters the rainwater collection trough. The rainwater in the rainwater collection trough is the preliminary filtered rainwater. The preliminary filtered rainwater flows to the water inlet of the rainwater collection pool through the slope at the bottom of the rainwater collection trough. The preliminary filtered rainwater is filtered again through the rainwater filter material at the water inlet as greening water and then enters the rainwater collection pool.

[0011] When the weather is dry, the soil moisture sensor on the inside of the green flower pool detects that the soil humidity is lower than the preset humidity. The sensor signal module instructs the drip irrigation center module to start the micro water pump through the signal line. The micro water pump draws rainwater to purify the purified water in the water pool and drips it into the soil of the green flower pool through the green flower pool drip pipe and drip irrigation branch pipe to keep the soil in the green flower pool moist.

[0012] When the weather is dry for a long time, the micro-water pump is used for drip irrigation. When the water level in the rainwater purification water supply pool drops and is lower than the water level of the water supply float valve, the water supply float valve automatically opens and tap water is used to replenish water in the rainwater purification water supply pool through the tap water pipe. When the water is replenished to the water level controlled by the water supply float valve, the float valve is closed and the water supply for drip irrigation is ensured by replenishing tap water. The rainwater purification water supply pool stores rainwater and tap water to moisturize the soil in the green flower pool through drip irrigation.

[0013] When the soil moisture sensor inside the green flower pond detects that the soil humidity is higher than the preset humidity, the sensor signal module instructs the drip irrigation center module to turn off the micro water pump through the signal line.

[0014] Beneficial effects: The rooftop greening rainwater and tap water moisturizing system of the present invention can collect and store rainwater during the rainy season. When the weather is dry, the collected rainwater is used to irrigate the green flowers and plants in the green flower pool. When the weather is dry for a long time and there is no rain, the greening water is supplemented by tap water. A large amount of tap water can be saved to irrigate the greening by collecting rainwater. When the weather is dry, the sensor signal module and the drip irrigation center module of the drip irrigation control box control the micro water pump to automatically irrigate the flowers and plants in the greening pool, which can reduce manual watering. The purified water or tap water supplied to the water pool through rainwater purification can ensure that the green flowers and plants in the flower pool grow luxuriantly without the phenomenon of plant withering.
