Description

Water collection and supply automatic device for roof greening

technical field

The invention relates to a water supply device, in particular to an automatic water collection and supply device for roof greening.

Background technique

With the continuous improvement of urbanization and industrialization, the environment on which people live has undergone tremendous changes. In order to improve the environment, every city has made full use of every green space in the process of development and construction. Increase the green area, but even so, still can not meet people's expected goals. In this case, using the roof of the building to open up gardens and green spaces, building a roof garden has become the most effective and direct measure to increase the urban green area with the most development prospects.

Roof greening can maintain the balance of CO2 and O2 in the air through the photosynthesis of plants, improve air quality, absorb harmful substances, absorb and fix dust, heavy metal elements and absorb harmful substances such as NH3 and SO2 in the atmosphere to reduce air pollution And has the function of reducing urban noise. The value of roof greening is not only that it can add green to the city, it is beneficial to adjust the urban climate environment, reduce rainwater loss, reduce the risk of urban waterlogging, reduce the pressure on urban drainage devices, suppress rainstorms and sandstorms, but also reduce the radiant heat on the roof of building materials. Weaken the heat island effect of the city, and bring people a fresh and pleasant visual effect of green grass, verdant seasons. If it can be well utilized and promoted to form an urban greening device in the sky, it will have an immeasurable effect on realizing the harmonious coexistence between man and nature and improving the urban environment.

However, roof greening is mainly a form of green space that uses plant materials to cover the roof of the platform. Since the roof greening is isolated from the ground, the water required for planting plants on the roof depends entirely on natural precipitation and watering. This has caused most of the roof gardens to be watered directly with tap water. Although the supply of water is guaranteed, the problem of excessive waste of water resources during watering is indeed beyond doubt.

Contents of the invention

The technical problem to be solved by the present invention is to provide an automatic device for collecting and supplying water for roof greening, which can effectively collect overflow water, rainwater, etc., solve the shortcomings of excessive waste of water resources during irrigation in roof greening, and realize automatic water collecting and supplying.

Set The water control tank 13 inside the water control chamber 2 communicates with the water collection tank 4 through the outlet pipe 16, and the end of the connecting rod 17 located in the water control chamber 2 is provided with a plug body 15 composed of a plurality of rubber plugs with different diameters. The diameter of the top gradually decreases from top to bottom, and the diameter of the top rubber plug is the same as the inner diameter of the outlet pipe 16 and extends into the water control tank 13;

In the water supply device, the water tank 1 is arranged on the top of the water control chamber 2 and communicates with the water control tank 13 in the water control chamber 2 through a pipeline;

The quality of the plastic ball at one end of the lever 11 is greater than the total mass of the parts at the other end.

The concave-convex drainage plate 8 is composed of a plurality of convex plates 8-1 arranged in parallel and a plurality of grooves 8-2 between two convex plates 8-1.

The double-layer water collection and diversion pipe group is composed of the upper water collection and diversion pipe group 5 and the lower water collection and diversion pipe group 9. The top of the water outlet of the upper water collection and diversion pipe group 5 is higher than each convex plate of the concave-convex drainage plate 8 8-1 top, the height of the top of the water outlet of the lower floor water collection diversion tube group 9 is consistent with the height of the bottom of each groove 8-2 of the concave-convex drainage plate 8.

The upper water collection and diversion pipe group 5 is composed of a plurality of upper water collection and diversion pipes arranged in parallel. Among the upper water collection and diversion pipes, an upper inner layer diversion pipe 5-2 is placed inside the upper outer casing 5-1 , the diameter of the upper inner layer diversion pipe 5-2 gradually increases from one end close to the rainwater diversion groove 6 to the other end, and the upper inner layer diversion pipe 5-2 is provided with a device that allows water to flow into the rainwater diversion groove 6 On the upper one-way valve 5-3 of the water collecting tank 4, an upper partition net 5-4 is installed on the water outlet near the water collecting tank 4 in the upper inner layer guide pipe 5-2.

The lower water collection and diversion pipe group 9 is composed of a plurality of lower water collection and diversion pipes arranged in parallel.

In dry weather (water shortage): firstly, the water tank 1 needs to be filled with water. Due to the lack of water, the plant root system absorbs the stored water from the water collection tank 4 through the upper water collection guide tube group 5, and the water level in the water collection tank 4 drops. , the plastic ball 10 at one end of the lever 11 descends, driving one end of the lever 11 to tilt downward, pushing the connecting rod 17 at the other end of the lever 11 to move upward, and the plug body 15 also rises thereupon, the water control tank 2 communicates with the outlet pipe 16, and starts to Water is injected into the water collection tank 4, and the water surface of the rainwater diversion tank 6 and the water collection tank 4 all rises. As the buoyancy of the water surface of the water collection tank 4 increases, the plastic ball 10 rises thereupon, and the connecting rod 17 is pulled to move downward, and the plug body 15 also follows After the drop, when the water in the water collection tank 4 reaches a certain amount (the rainwater diversion tank and the liquid level on both sides of the water collection tank are equal again), the plug body 15 also descends to the position where the top rubber plug blocks the water outlet pipe. When the water inflow stops, the automatic water collection and water supply of the roof is completed.

The specific implementation of the present invention is not limited by the above-mentioned examples, as long as various insubstantial improvements of the method concept and technical solution of the present invention are adopted, or the concept of the present invention and the technical solution are directly applied to other occasions without improvement All are within the protection scope of the present invention.
