[0002] The three-dimensional green plants in landscape garden design are a type of urban greening method with great potential, which can effectively improve the urban ecological environment quality and create a comfortable living environment. The basic components of landscape gardens can be divided into two categories. One category is soft things, such as trees, water bodies, gentle winds, gentle rains, sunlight, and the sky. The other category is hard things, such as pavements, walls, railings, and landscape structures. Among the hard landscapes, plant materials are mostly used, such as live plants, succulents, or decorative craft flowers. During the setting up of garden parks, garden communities, garden streets, and garden cities, for the sake of overall aesthetics and convenient management, the reunion or array design is often adopted, giving visitors a more pleasant visual effect. After having a standardized shape design, it is also beneficial to uniformly spray and irrigate the plants.

[0003] After retrieval, Chinese Patent No. CN117716985A discloses an ecological-friendly rainwater collection and recycling garden device and its usage method. Although it can detect whether the soil where the plants are located is in a wet state and accurately make water or nutrient solution reach the roots of the plants, enabling plants in different growth stages to obtain good spraying and irrigation effects, however, with the growth of the green plants, the sprinkler heads cannot be adjusted, resulting in the lack of water irrigation at the top of the green plants, and at the same time, the sprinkler irrigation consumes a large amount of water resources. For this reason, we propose an ecological-friendly rainwater collection and recycling garden device. Content of the Utility Model

[0004] The purpose of the utility model is to provide an ecological-friendly rainwater collection and recycling garden device to solve the problems raised in the above background technique, that is, with the growth of the green plants, the sprinkler heads cannot be adjusted, resulting in the lack of water irrigation at the top of the green plants, and at the same time, the sprinkler irrigation consumes a large amount of water resources.

A sewage discharge pipe is fixedly connected to the sewage outlet at the lower end of the sewage discharge groove through a third electromagnetic valve.

[0006] As a further scheme of the present utility model, the main water pipe is fixedly installed in a through hole in the exact middle of the mounting frame. Signal lines and power lines of the first electromagnetic valve and the second electromagnetic valve are electrically connected to the control box through a first wire conduit. Signal lines and power lines of the submersible pump liquid level sensor are both electrically connected to the control box through a second wire conduit.

[0012] As a further solution of the utility model, the signal wire and the power cord of the third electromagnetic valve are connected to the control box through the sixth wire tube.

[0013] The technical effects and advantages of the utility model are as follows:

[0014] 1. Through the arranged water replenishing mechanism, during rain, the sediment, leaves, etc. carried in the rainwater can be intercepted by the intercepting frame, enabling the rainwater to enter the reservoir. The water level in the reservoir is monitored by the liquid level sensor. When the water level in the reservoir is lower than the preset minimum value, the control box controls the second electromagnetic valve to open, allowing the municipal tap water to enter the reservoir from the water inlet pipe. After the liquid level sensor detects that the water level in the reservoir reaches the preset maximum value, the control box controls the second electromagnetic valve to close. After reaching the set sprinkling time every day, the control box controls the first electromagnetic valve to open, and at the same time, the submersible pump starts to work, and the water in the reservoir enters the main water pipe for sprinkling. It can collect and utilize the rainwater on rainy days, and after natural sedimentation of the sediment, it can be used for sprinkling. At the same time, it can timely replenish the reservoir with water to ensure sufficient water in the reservoir in case of sudden water cut-off and other situations, and avoid the lack of water for the green plants, which may hinder their growth.

[0015] 2. Through the arranged automatically adjustable sprinkling mechanism, according to the growth rules of the green plants in each area, a time for the angle transformation of the first sprinkler head and the second sprinkler head is set. After reaching the set time, the control box controls the corresponding stepper motor to rotate by a corresponding angle, so that the highest sprinkling point of the first sprinkler head can reach the highest point of the green plants, and at the same time, the lowest sprinkling point of the second sprinkler head can always sprinkle to the roots of the green plants, ensuring that there is enough water to moisten the roots of the green plants, enabling the entire sprinkler irrigation equipment to be adjusted according to the growth rules of the green plants, and the sprinkler irrigation effect is better.

[0016] 3. Through the provided dirt cleaning mechanism and sewage discharging mechanism, after reaching the preset maintenance time, a cleaning agent is added into the reservoir. The control box controls the servo motor to rotate electrically, driving the mud scraping frame to perform circular motion on the inner wall of the reservoir, scraping off the dirt on the inner wall of the reservoir. It is convenient and fast, without the need for manual cleaning. While cleaning the dirt, the control box will control the third solenoid valve to open, so that the dirt scraped from the reservoir falls from the anti-blocking grille after being crushed, flows out from the sewage discharge groove, and finally is discharged from the sewage pipe to increase nutrients in the soil, which can avoid excessive bacteria breeding in the reservoir and reduce the harm caused by the sprayed water mist hitting tourists' faces.
