Landscape rainwater recovery processing device

Technical Field

The invention belongs to the technical field of rainwater recovery and treatment, and particularly relates to a landscape rainwater recovery and treatment device.

Background

The garden is a beautiful natural environment and a rest area which are created by applying engineering technology and artistic means in a certain region and by means of land form improvement, tree planting, flower and grass planting, building of buildings, garden path arrangement and the like, and is called as a garden. Gardens can use a large amount of water resources in plant irrigation and daily use, China is a country with relatively lack of water resources, and the water resources used for gardens at present mainly come from tap water, and the water pressure is great. In rainy days, a large amount of rainwater can permeate downwards through the permeable road and finally run off in vain. Currently, the method is not specially used for recycling and treating the downward rainwater, so that a large amount of water resources are wasted.

Disclosure of Invention

The invention aims to provide a landscape rainwater recycling device to solve the problem that water resources penetrating to the ground cannot be effectively recycled.

In order to achieve the purpose, the scheme of the invention is as follows: the garden landscape rainwater recycling device comprises a filtering mechanism, a collecting box and a water storage box, wherein the water storage box is positioned underground of a permeable road, and a water pipe positioned in the permeable road is connected to the water storage box; the collecting box is positioned on the ground, and the filtering mechanism is positioned above the collecting box; a touch delay switch is arranged in the upper part of the water storage tank, a floating block is arranged in the water storage tank, and a bulge which can be contacted with a touch sheet on the touch delay switch is arranged on the floating block; a first water pump is installed on the side wall of the water storage tank and is electrically connected with the touch delay switch; the water inlet end of the first water pump is connected with a water inlet pipe, and the water inlet pipe is communicated with the side wall of the water storage tank; the water outlet end of the first water pump is connected with a water outlet pipe, and the water outlet pipe is communicated with the upper part of the filtering mechanism; the lower surface of the filtering mechanism is connected with a drain pipe communicated with the collecting box.

The working principle and the beneficial effects of the scheme are as follows: in rainy days, rainwater falls on the water permeable passage, then gradually permeates downwards, and finally enters the water storage tank through the water pipe. Along with the continuous entering of rainwater, the water in the water storage box is more and more, and the floating block rises under the effect of water and is more and more close to the touch delay switch. When water in the water storage tank is to be stored fully, the protrusions on the floating blocks are in contact with the touch pieces on the touch delay switches, the touch delay switches control the first water pump to work for a period of time, the first water pump pumps water in the water storage tank out through the water inlet pipe and then conveys the water into the filtering mechanism through the water outlet pipe, and the rainwater finally enters the collecting tank through the water discharge pipe after being filtered by the filtering mechanism. In the working period of the first water pump, the water in the water storage tank is reduced, the floating block gradually descends, and the protrusion is separated from the contact with the touch sheet on the touch time delay switch.

In the scheme, water resources penetrating underground can be effectively collected by arranging the water pipe, the water storage tank and other structures; the floating block and the touch delay switch are arranged, when water in the water storage tank is full, the first water pump can be automatically controlled to work for a period of time to realize water pumping, the automation degree is high, and manual operation is not needed.
