Description

Technical Field

[0001] This utility model relates to the technical field of rainwater harvesting and utilization, and in particular to an integrated device for rainwater harvesting and intelligent irrigation. Background Technology

[0002] Traditional irrigation methods rely on municipal water supply or groundwater, resulting in significant water waste and high costs. Simultaneously, rainwater resources are not effectively utilized, leading to both urban flooding and drought problems. Existing technologies often employ independent designs for rainwater harvesting and irrigation, which have the following shortcomings.

[0003] The rainwater filtration system has a single filtration level, which cannot effectively remove impurities such as mud, leaves, and pollutants from rainwater; the irrigation system relies on manual control and cannot achieve intelligent start-up and shutdown based on soil moisture, weather, and other conditions, resulting in water waste; each functional module operates independently, with low integration, large footprint, and complex installation and maintenance; and it lacks energy-saving design, resulting in high energy consumption. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated rainwater harvesting and intelligent irrigation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integrated rainwater harvesting and intelligent irrigation device includes a rainwater harvesting channel, a primary filter tank, a water purification tank, a disinfection channel, a purified water storage tank, an irrigation system, and a controller. The rainwater harvesting channel is connected to the primary filter tank, which is connected to the top of the water purification tank via a purification pumping pipe. The bottom of the side wall of the water purification tank is connected to the disinfection channel via a pipe, and the disinfection channel is connected to the purified water storage tank. The purified water storage tank is connected to the irrigation system via an irrigation pumping pipe. A pumping pump is installed on the purification pumping pipe, and an irrigation pump is installed on the irrigation pumping pipe. Both the pumping pump and the irrigation pump are connected to the controller.

[0007] The rainwater collection channel is equipped with sloping diversion slopes on both sides to guide rainwater to flow quickly into the collection channel; the sloping diversion slopes are equipped with a primary filter plate and a secondary filter plate from top to bottom to intercept large particulate impurities in the rainwater, such as leaves, branches, and sand and gravel, thus initially purifying the rainwater; the rainwater collection channel is connected to the primary filter tank.

[0008] A water level sensor is installed on the inner wall of the primary filter tank to monitor the water level in real time. The water level sensor is connected to a controller. The primary filter tank is connected to the water purification tank through a purification pump pipe. The end of the purification pump pipe is inside the primary filter tank and is equipped with a filter head to prevent particulate impurities from entering subsequent pipelines and pumps and affecting their lifespan. A water pump is installed on the purification pump pipe and is connected to the controller. The water level data collected by the water level sensor is fed back to the controller, which controls the start and stop of the water pump. When the water level reaches a set threshold, the controller starts the water pump to transport the pre-filtered rainwater to the water purification tank; when the water level is below the minimum threshold, the water pump stops running.

[0009] The water purification tank is equipped with, from top to bottom, a conical flow guide plate, a sand and gravel filter layer, an activated carbon filter layer, a zeolite filter layer, and a PP cotton filter layer. The conical flow guide plate has evenly distributed through holes, and its conical surface design ensures uniform water flow and avoids short-circuiting. The sand and gravel filter layer removes fine suspended solids and colloids; the activated carbon filter layer adsorbs organic matter, pigments, and odors from the water; the zeolite filter layer removes heavy metal ions and pollutants such as ammonia nitrogen; and the PP cotton filter layer traps micron-sized impurities, ensuring clear effluent. The purification pump pipe is connected to the top of the water purification tank, and water flows from top to bottom through each filter layer. The bottom of the side wall of the water purification tank is connected to a disinfection channel via a pipe.

[0010] The disinfection channel is equipped with a channel cover plate at the top and an ultraviolet disinfection lamp at the bottom of the channel cover plate, which effectively kills bacteria, viruses and other microorganisms; a solar panel is installed on the top of the channel cover plate, which provides power to the ultraviolet disinfection lamp; the disinfection channel is connected to a purification water storage tank.

[0011] The irrigation system includes a main pipeline, branch pipelines, and soil moisture sensors. The irrigation pipelines are connected to the main pipeline, and multiple branch pipelines are connected to the main pipeline. Each branch pipeline has a corresponding irrigation zone. Solenoid valves are installed on the branch pipelines to control the water flow in each irrigation zone. Soil moisture sensors are installed in the irrigation zones corresponding to the branch pipelines to monitor the soil moisture content in real time. The soil moisture sensors and solenoid valves are both connected to a controller. The controller presets upper and lower limits for soil moisture. When the soil moisture in an irrigation zone is lower than the lower limit, the controller opens the solenoid valve and irrigation pump of the corresponding branch pipeline to carry out irrigation. When the moisture reaches the upper limit, the solenoid valve and pump are automatically shut off to achieve precise water-saving irrigation.

[0012] The beneficial effects of this utility model are as follows:

[0013] Multi-stage filtration ensures water quality: Through a primary filter plate, a secondary filter plate, a five-stage purification layer, and ultraviolet disinfection, it can effectively remove suspended solids, organic matter, heavy metals, and microorganisms from rainwater, and the effluent water quality meets irrigation needs.

[0014] Intelligent control and precise water saving: The soil moisture sensor and controller work together to automate and precisely control irrigation, saving water compared to traditional manual irrigation;

[0015] Energy-saving design reduces energy consumption: solar panels power the ultraviolet disinfection lamps, reducing reliance on external power sources; water pumps and irrigation pumps start and stop based on real-time data, avoiding ineffective operation and reducing energy consumption.

The primary filter plate 12 is a stainless steel mesh with an 8mm aperture, installed 10cm from the top of the channel. The secondary filter plate 13 is a nylon filter with a 2mm aperture, installed 15cm below the primary filter plate 12.

[0025] A water level sensor 23 is installed on the inner wall of the primary filter tank 2, and the water level sensor 23 is connected to the controller 9. The liquid level data collected by the water level sensor 23 is fed back to the controller 9, and the controller 9 controls the start and stop of the water pump 7.

The controller 9 presets upper and lower limits for soil moisture, with an upper limit of 80%RH and a lower limit of 50%RH.

[0029] Working principle:

[0030] Rainwater collection and primary filtration: During rainfall, rainwater flows into the rainwater collection channel through the sloping diversion slope, and then passes through the primary filter plate and the secondary filter plate in sequence to remove large particulate impurities before entering the primary filter tank to complete the initial sedimentation and filtration.

[0031] Water purification and disinfection: When the water level in the initial filter reaches the high water level threshold (60cm), the controller starts the water pump, which transports rainwater through the purification pump pipe to the top of the water purification tank. The water flow is evenly dispersed through the conical guide plate, passing sequentially through sand, activated carbon, zeolite, and PP cotton filter layers to remove various pollutants before flowing into the disinfection channel. Ultraviolet disinfection lamps, powered by solar panels, continuously sterilize and disinfect the water flow before it finally flows into the purified water storage tank for storage.

[0032] Intelligent irrigation: The controller collects soil moisture sensor data from each irrigation area at regular intervals. When the humidity in a certain area is lower than 50%RH, the controller executes the following sequence: open the solenoid valve of the corresponding branch pipe; start the irrigation pump to transport water from the purified water storage tank to the irrigation area through the main pipe and branch pipes; continue irrigation until the soil humidity reaches 80%RH, then the controller closes the solenoid valve and irrigation pump to complete one irrigation cycle.
