Description

TECHNICAL FIELD

[0001] The application relates to the technical field of rainwater collection and purification devices, in particular to a green building rainwater collection and purification device. BACKGROUND

[0002] Rainwater is one of the most important material resources for human survival and development and is an indispensable part of the earth's water cycle. Rainwater has the effect of purifying the environment and can reduce dust in the air. A rainstorm can wash away garbage on the ground, carry away unpleasant odors and dilute toxic gases. Rainwater is also beneficial to reservoir storage and can replenish groundwater. Because of the purifying effect of rainwater, in areas with serious air and environmental pollution, the rainwater falling to the ground is often of poor quality. Acid rain is a typical example. In the early stage of rainfall, rainwater directly washes buildings, the ground and the like, and dust and oil stains enter the rainwater from the buildings, the ground and the like. Therefore, the early stage of rainwater is seriously polluted. Rainwater that does not have serious air pollution and no secondary pollution on the ground can enter the third class of water quality. Because such rainwater can be naturally clarified, the physicochemical indexes thereof can meet the third class of surface water standards. After being purified, rainwater can be used for irrigating crops, landscaping, urban greening, road washing, cooling water replenishment, toilet flushing and some other non-living water uses.

[0003] Compared with the prior art, when rainwater enters the filter device, it may not flow uniformly to the filter device, so that the filter material in some areas may bear too much rainwater flow, while the flow in other areas may be insufficient, which will lead to uneven filtering efficiency. Some areas may be quickly clogged due to overload, while other areas may not be able to fully play a filtering role due to insufficient flow. CONTENT OF THE UTILITY MODEL

[0004] In view of the shortcomings of the prior art, the application provides a green building rainwater collection and purification device, which has the advantages of increasing the filtering effect, and solves the problems that when rainwater enters the filter device, it may not flow uniformly to the filter device, so that the filter material in some areas may bear too much rainwater flow, while the flow in other areas may be insufficient, which will lead to uneven filtering efficiency. Some areas may be quickly clogged due to overload, while other areas may not be able to fully play a filtering role due to insufficient flow.

[0005] To achieve the above object, the present application provides the following technical scheme: a green building rainwater collecting and purifying device, comprising a building body, a roof fixedly connected to the upper end of the building body, a flow guide plate fixedly connected to the upper end of the roof, water guide groove pipes fixedly connected to the two sides of the roof, first filter plates fixedly connected to one side of the interiors of the two water guide groove pipes, draining plates fixedly connected to one side of the bottom ends of the two first filter plates, baffles fixedly connected to one side of the upper ends of the two first filter plates, water outlet pipes fixedly connected to one side of the bottom ends of the two water guide groove pipes, hoses fixedly connected to the bottom ends of the two water outlet pipes, and a water collecting pipe fixedly connected to the ends of the two hoses away from the water outlet pipes.

The first filter plates and the draining plates arranged in the interiors of the water guide groove pipes can preliminarily filter the rainwater, remove large-particle impurities and garbage, and the baffles can prevent leaves and other sundries from entering the water guide groove pipes. Through the arrangement of the water outlet pipes at the bottom of the water guide groove pipes and the hoses connected to the water collecting pipe, the rainwater can uniformly flow to the water collecting pipe, avoiding the problem of uneven flow distribution of the rainwater in the filtering device, and helping to improve the filtering efficiency of the filtering device and prolong the service life thereof. The device collects and utilizes rainwater, reduces the dependence on traditional water resources, and helps to reduce the pressure of urban rainwater discharge.

[0007] Further, a filter box is fixedly connected to one side of the building body, and a plurality of ultraviolet lamp tubes are arranged in annular arrays and fixedly connected to one side of the bottom end of the interior of the filter box.

The ultraviolet lamp tubes can effectively kill bacteria, viruses and other microorganisms in the rainwater by emitting ultraviolet light waves, which helps to ensure the safety and hygiene of the collected rainwater.

[0009] Further, two sliding grooves are formed in the two sides of the interior of the filter box, and filter square pipes are slidingly connected to the interiors of two groups of the four sliding grooves, and three second filter plates are fixedly connected to the interior of each filter square pipe in linear arrays.

[0010] Through the above scheme, three second filter plates are fixedly connected to the interior of each filter square pipe in linear arrays, which can increase the contact area between the rainwater and the filtering material, thereby improving the filtering efficiency. The three second filter plates are made of different filtering materials or have different filter hole diameters, realizing multi-stage filtration and effectively removing small particles, suspended solids and other impurities in the rainwater. The filter square pipes are slidingly connected to the interior of the filter box through the sliding grooves, and this modular arrangement makes the installation, disassembly and replacement of the filter square pipes simple and fast.

[0011] Further, the filter box is internally fixedly connected with a collecting plate, the filter box is internally fixedly connected with a water collecting tank at the bottom end, and the water collecting tank is fixedly connected with a backflow pipe at one side.

[0012] Through the above scheme, the filter box is internally provided with the collecting plate and the water collecting tank, which can effectively collect the rainwater after the filtering treatment and store the rainwater in the water collecting tank.

[0013] Further, the filter box is rotatably connected with a box door at one side through a hinge.

[0014] Through the above scheme, the box door enables the user to conveniently open and close the filter box, thereby facilitating the daily maintenance and repair work on the internal filter square pipe, second filter plate and other components.

[0015] Further, the water collecting pipe is fixedly arranged in the filter box.

[0016] Through the above scheme, the water collecting pipe is fixedly arranged in the filter box, so that the collected rainwater uniformly enters the filter box.

[0017] Further, the collecting plate corresponds to the water collecting tank.

[0018] Through the above scheme, the corresponding arrangement of the collecting plate and the water collecting tank ensures that the rainwater can directly and efficiently flow into the water collecting tank after the filtering, reduces the loss of the rainwater in the flowing process, and improves the collection efficiency.

[0019] Further, one end of the backflow pipe away from the water collecting tank penetrates through the filter box and is fixedly connected with the building body.

[0020] Through the above scheme, the purified rainwater can re-enter the building body through the backflow pipe, realizes the recycling of the rainwater, saves the water resources, reduces the water consumption of the building, and conforms to the concept of green building energy saving and environmental protection.

[0021] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:
