The rainwater collection and purification device is an environmentally friendly and efficient device. Its design and application are aimed at maximizing the utilization value of rainwater, reducing dependence on public water resources, and complying with the environmental protection concept of green buildings.

[0003] For example, the patent with publication number CN210766990U discloses a rainwater collection and purification device, including: a water storage tank; a water collecting tank, which is rotatably supported on the top of the water storage tank and connected to the water storage tank; a water baffle, which is rotatably mounted on the top of the water collecting tank and can block rainwater against the wind, so that rainwater flows into the water collecting tank along the water baffle; a filter screen, which is detachably arranged at the connection between the water collecting tank and the water storage tank and can coarsely filter impurities in rainwater; a sludge purification device, which is arranged in the water storage tank and can filter out silt in rainwater. The utility model is provided with a rotatable water collecting tank on the top of the water storage tank, and by rotating the wind shield plate, the wind shield plate is always located in the windward direction, so that more rainwater can be collected, and a guide device and a multi-stage filter plate are arranged in the water storage tank, so that the purification effect is good.

[0004] In the prior art, the collected rainwater is mostly transported through pipes and stored in a collection tank. Since the collected rainwater often contains sediment, although a filter plate or activated carbon is used to filter the sediment, it is difficult to remove the sediment, resulting in the filter device being easily clogged by sediment after long-term use, resulting in poor filtering effect. A green building rainwater collection and purification device is now proposed to solve the above problems. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides a green building rainwater collection and purification device.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a green building rainwater collection and purification device, comprising a collection tank, a water inlet pipe is fixedly connected to the top of the collection tank, a water diversion funnel is fixedly connected to the top of the guide cover, a connecting membrane is fixedly connected to the middle of the water inlet pipe, a separator is fixedly connected to the inner ring of the connecting membrane, water filter holes are evenly opened on the separator, a limiting rod is fixedly connected to the bottom of the middle of the separator, a spring is sleeved on the outer end of the limiting rod, a bellows is sleeved on the outer end of the spring, a fixing plate is fixedly connected to the bottom end of the bellows, a slag discharge port is opened in a ring array in the middle of the water inlet pipe, a guide cover is fixedly connected to the middle of the outer circumference of the water inlet pipe, and a guide ring is fixedly connected to the outer side of the water inlet pipe.

[0007] Preferably, the water diversion funnel is a funnel-shaped structure that is wide at the top and narrow at the bottom, and the separator is an umbrella-shaped structure that is narrow at the top and wide at the bottom.

[0009] Preferably, the outer peripheral surface of the bottom end of the limiting rod is movably connected to the fixing plate, and the top end of the bellows is fixedly connected to the separator.

[0010] Preferably, the upper and lower ends of the spring are fixedly connected to the separator and the fixing plate respectively.

[0011] Preferably, the guide ring is tilted downward from the inside to the outside, and the slag discharge port is located between the guide ring and the guide cover.

[0012] Preferably, the outer end of the fixing plate is fixedly connected to the water inlet pipe, the outer end of the fixing plate is high and the middle is low, and a circular array of water-permeable grooves is provided on the fixing plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model achieves good filtering effect by coordinating structures such as a water diversion funnel, a connecting membrane, a separator, a water filter hole, and a spring. When rainwater enters the water inlet pipe through a pipeline, the rainwater falls from top to bottom under the guidance of the water diversion funnel, and the water flows downward along the surface of the separator. The water can flow downward through the water filter hole and enter the collection tank through the water-permeable groove of the fixed plate, while a part of the silt can pass through the slag discharge port through the impact of the water and be discharged through the guidance of the guide ring, while a part of the silt is blocked on the water filter hole. Since the water can impact the separator downward, the spring is compressed, so that the gas is allowed to recoil upward through the water filter hole.

[0015] The blocked mud and sand can be blown out upwards, and through the up and down shaking of the separator, the mud and sand can be discharged from the slag discharge port, so that the filtering effect of the device is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 5 As shown, the utility model provides a green building rainwater collection and purification device, including a collection tank 1, a water inlet pipe 2 is fixedly connected to the top of the collection tank 1, a water diversion funnel 4 is fixedly connected to the top of the guide cover 3, a connecting membrane 5 is fixedly connected to the middle of the water inlet pipe 2, a separator 6 is fixedly connected to the inner ring of the connecting membrane 5, and water filtering holes 7 are evenly opened on the separator 6, a limiting rod 8 is fixedly connected to the bottom of the middle of the separator 6, a spring 9 is sleeved on the outer end of the limiting rod 8, a bellows 10 is sleeved on the outer end of the spring 9, a fixing plate 11 is fixedly connected to the bottom end of the bellows 10, a slag discharge port 12 is opened in a ring array in the middle of the water inlet pipe 2, a guide cover 3 is fixedly connected to the middle of the outer circumference of the water inlet pipe 2, and a guide ring 13 is fixedly connected to the outer side of the water inlet pipe 2;

[0024] When rainwater enters the water inlet pipe 2 through the pipe, the rainwater falls from top to bottom under the guidance of the water diversion funnel 4, and the water flows downward along the surface of the separator 6. The water can flow downward through the water filter hole 7 and enter the collection tank 1 through the water permeable groove of the fixed plate 11, and a part of the silt can pass through the slag discharge port 12 through the impact of water and be discharged through the guidance of the guide ring 13, while a part of the silt is blocked on the water filter hole 7. Since the water can impact the separator 6 downward, the spring 9 is compressed, so that the gas can recoil upward through the water filter hole 7, which can blow out the blocked silt upward, and through the up and down shaking of the separator 6, the silt can be discharged from the slag discharge port 12, so that the filtering effect of the device is good;

[0025] It is worth noting that since the amount of rainwater collected by the green building is affected by environmental factors such as precipitation and wind, the amount of water will vary when the rainwater is input into the water inlet pipe 2 through the pipe, so that the force of the rainwater impacting the separator 6 will change continuously, so that the separator 6 can compress the spring 9 downward, so that the separator 6 can vibrate up and down, and shake out the mud and sand downward.

[0026] like Figures 1 to 5 As shown, the water diversion funnel 4 is a funnel-shaped structure that is wide at the top and narrow at the bottom, the separator 6 is an umbrella-shaped structure that is narrow at the top and wide at the bottom, the water filtering hole 7 is an hourglass-shaped hole that is wide at both ends and narrow in the middle, the connecting membrane 5 is made of an elastic waterproof material, the outer peripheral surface of the bottom end of the limit rod 8 is movably connected to the fixed plate 11, the top of the bellows 10 is fixedly connected to the separator 6, the upper and lower ends of the spring 9 are respectively fixedly connected to the separator 6 and the fixed plate 11, the outer end of the fixed plate 11 is fixedly connected to the water inlet pipe 2, the outer end of the fixed plate 11 is high in height and low in the middle, a ring array of water-permeable grooves is provided on the fixed plate 11, the guide ring 13 is arranged to be tilted downward from the inside to the outside, and the slag discharge port 12 is located between the guide ring 13 and the guide cover 3;

[0027] Since the water diversion funnel 4 is a funnel-shaped structure that is wide at the top and narrow at the bottom, rainwater can impact the middle part of the separator 6 more concentratedly, and the separator 6 is an umbrella-shaped structure that is narrow at the top and wide at the bottom, which can facilitate the downward flow of water and sediment. The water filter hole 7 is an hourglass-shaped hole that is wide at both ends and narrow in the middle, which increases the surface area of ​​the separator 6 and can effectively block the sediment. When the separator 6 moves downward, the gas can be quickly ejected through the water filter hole 7, which can effectively prevent the blockage of sediment.

[0028] The working principle and use process of this utility model:

[0029] First, when rainwater enters the water inlet pipe 2 through the pipe, the rainwater falls from top to bottom under the guidance of the water diversion funnel 4, and the water flows downward along the surface of the separator 6. The water can flow downward through the water filter hole 7 and enter the collection tank 1 through the water permeable groove of the fixed plate 11. A part of the silt can pass through the slag discharge port 12 through the impact of water and be discharged through the guidance of the guide ring 13. A part of the silt is blocked on the water filter hole 7. Since the water can impact the separator 6 downward, the spring 9 is compressed, so that the gas can recoil upward through the water filter hole 7, which can blow out the blocked silt upward, and through the up and down shaking of the separator 6, the silt can be discharged from the slag discharge port 12 to complete the operation.
