[0003] Rainwater collection devices for green buildings include roof water collection systems, ground water collection systems, etc., aiming to effectively collect, store and utilize rainwater, reduce the dependence on municipal water supply, reduce water resource waste, and provide a sustainable water source.

[0004] Existing rainwater collection devices for green buildings have some deficiencies. On the one hand, most of the existing rainwater collection devices have only one filter screen. However, after long-term use, the filtering device may become blocked, aged, or even damaged. Moreover, most of the filtering equipment of the existing rainwater collection devices adopts an integrated design, which is rather troublesome and inconvenient for cleaning and replacement. On the other hand, most of the existing rainwater collection devices are communicated with the outside air. When the rainwater in the collection bucket is full and stored, since the device is not airtight and is exposed to the outdoor high-temperature irradiation for a long time, the rainwater will evaporate, reducing the utilization of rainwater and causing waste. Therefore, a rainwater collection device for green buildings is proposed to solve the above problems. Summary of the Utility Model

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figure 1 - Figure 2, an embodiment provided by the present utility model: a rainwater collection device for a green building, including a collection bucket 1, which is installed at the end of the roof drain pipe of the green building, so that the rainwater collected from the top inclined surface of the green building flows into it along the drain pipe, facilitating its recycling. A diversion pipe 2 penetrates and is fixedly connected to the center position of the top of the collection bucket 1. By setting the diversion pipe 2, the rainwater entering the collection port 6 flows along its inner wall into the interior of the collection bucket 1. A moving frame 3 penetrates and is slidably connected to the center position of the diversion pipe 2. Two groups of through holes are respectively formed on the surface of the moving frame 3 for pushing the moving frame 3 to the corresponding interface of the diversion pipe 2. The limiting rod 53 is inserted and fixed with its through hole. Two groups of filter nets 4 are detachably installed at the bottom end of the inner wall of the moving frame 3. Two groups of cavities are formed on the surface of the moving frame 3, facilitating the disassembly and replacement of the filter nets 4 inside the moving frame 3. A limiting component 5 is arranged on the outer wall of the diversion pipe 2. A collection port 6 is fixedly connected to the outer wall of the top end of the diversion pipe 2. A drain pipe A7 is fixedly connected to the outer wall of the left top end of the collection bucket 1. When the rainwater in the collection bucket 1 is collected to a certain height, the rainwater will be discharged out of the bucket through the drain pipe A7, and will not submerge the position above the support platform 94, thus not damaging the device. A drain pipe B8 is fixedly connected to the outer wall of the right bottom end of the collection bucket 1. A valve is arranged on the surface of the drain pipe B8. Residents can control the valve to use the rainwater in the collection bucket 1, so that it can be used. A shielding component 9 is arranged at the top end of the inner wall of the collection bucket 1. The limiting component 5 includes a connecting block 51; a limiting rod 52 is elastically connected to the inner wall of the connecting block 51 through a limiting spring 53.

[0034] Refer to Figure 2 - Figure 3 , two groups of through holes are respectively formed on the surface of the moving frame 3. The bottom end of the outer wall of the limiting rod 53 is inserted into the inner wall of the through hole. The insertion between the two enables the moving frame 3 to drive the two groups of filter nets 4 to slide to the through hole position of the diversion pipe 2 for insertion and fixation. One end of the limiting spring 52 is fixedly connected to the inner wall of the connecting block 51, and the other end of the limiting spring 52 is fixedly connected to the surface of the limiting rod 53. The function of the limiting spring 52 is to automatically reset the position of the limiting rod 53 after being pulled. The limiting rod 53 penetrates and is slidably connected to the inner wall of the connecting block 51. The connecting block 51 is fixedly connected to the outer wall of the center position of the diversion pipe 2. The top end of the outer wall of the limiting rod 53 penetrates and is slidably connected to the inner wall of the diversion pipe 2.

[0035] Refer to Figure 3 - Figure 5, the shielding component 9 includes a sealing cover rod 91. The function of the sealing cover rod 91 is to seal the bottom end of the diversion pipe 2, so that the collection bucket 1 is sealed, preventing it from being exposed to outdoor high-temperature irradiation and causing the rainwater collected in the collection bucket 1 to evaporate. The bottom end of the sealing cover rod 91 penetrates and slides on the inner wall of the reset sleeve 92. The bottom end of the outer wall of the sealing cover rod 91 is elastically connected to a support platform 94 through a reset spring 93. Multiple groups of through holes are provided on the surface of the support platform 94 for rainwater to fall, preventing rainwater from accumulating on the surface of the support platform 94 during the falling process. Three support rods 95 are fixedly connected to the top surface of the support platform 94. The function of the support rods 95 is to support the support platform 94 and the objects on the surface of the support platform 94. One end of the reset spring 93 is fixedly connected to the bottom outer wall of the sealing cover rod 91, and the other end of the reset spring 93 is fixedly connected to the top surface of the support platform 94. The function of the reset spring 93 is that when the sealing cover rod 91 moves downward on the inner wall of the reset sleeve 92 under the impact of rainwater, the reset spring 93 is compressed. When the rain stops, the sealing cover rod 91 is subjected to the restoring force of the reset spring 93 and moves upward. The outer wall of the top end of the sealing cover rod 91 is in contact with the inner side wall of the diversion pipe 2. The top ends of the outer walls of the three support rods 95 are fixedly connected to the top end of the inner wall of the collection bucket 1, and the bottom end of the reset sleeve 92 is fixedly connected to the top surface of the support platform 94.

[0036] Working principle: When collecting rainwater on a rainy day, the rainwater enters the diversion pipe 2 through the collection port 6, and then passes through the filter screen 4 at the bottom end of the moving frame 3 arranged at the central position of the diversion pipe 2, thereby filtering out the impurities in the rainwater. After a period of rainwater collection, when replacing the filter screen 4, by pulling out the limit rod 53, the limit spring 52 is compressed, pushing the moving frame 3 so that the new filter screen 4 in the moving frame 3 is aligned with the through holes of the diversion pipe 2. Release the limit rod 53, and the limit spring 52 is subjected to the restoring force, so that the limit rod 53 is inserted and fixed with the through holes on the surface of the moving frame 3. At the same time, the used filter screen 4 is disassembled, replaced or cleaned, and so on, so that the rainwater can be filtered well.

[0037] When the rainwater enters the collection bucket 1 through the diversion pipe 2, the impact force of the rainwater causes the sealing cover rod 91 to move downward, and the reset spring 93 moves downward on the inner wall of the reset sleeve 92. When the rain stops, the reset spring 93 is driven by its own restoring force to drive the sealing cover rod 91 to contact the inner wall hole at the top end of the collection bucket 1, thereby sealing the inlet of the diversion pipe 2. At the same time, when the rainwater in the collection bucket 1 is collected to a certain height in the bucket, the water will be discharged out of the bucket through the drain pipe A7, and the rainwater will not soak the support platform 94 and the support rods 95 at the top end in the collection bucket 1, resulting in damage over a long time. When the collected rainwater does not reach a certain height and residents need to use the collected rainwater, the amount of the collected rainwater used is controlled through the valve provided on the drain pipe B8.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
