Description

Technical Field

[0001] The present invention relates to the technical field of green buildings, and specifically to a rainwater recycling device for green buildings in arid pastoral areas. Background Art

[0002] In arid pastoral areas, due to the unstable and uneven distribution of natural rainfall, the scarcity of water resources is an objective and long-existing problem. There are many technical problems in traditional rainwater collection and utilization methods, especially in the design and implementation of rainwater recycling devices.

[0003] In the design and application of existing rainwater recycling devices, there is a lack of the function of automatically adjusting the angles of the diversion device and the filtering device according to the amount of rainfall. When the rainfall is too large, the rainwater flow rate is high and the velocity is fast. A large amount of rainwater may cause backflow into the house because it cannot be collected and filtered in time, which not only fails to effectively utilize rainwater resources, but may also damage the device itself, the house and the surrounding environment; while when the rainfall is too small, due to the fixed angle of the device, the covered area of the device is small and the rainwater recovery amount is low, resulting in waste of rainwater resources. Summary of the Invention

[0004] The present invention aims to provide a rainwater recycling device for green buildings in arid pastoral areas, which is provided with a diversion component and a filtering component to divert and filter rainwater respectively. A spring is provided between the diversion plate of the diversion component and the building wall, so that the diversion plate can automatically adjust the included angle between it and the building wall according to the amount of rainwater. The movable filter screen of the filtering component is connected to the diversion plate through a linkage component, so that the movable filter screen can rotate with the rotation of the linkage plate to ensure the rainwater recycling efficiency. The problems in the background art are solved.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A rainwater recycling device for green buildings in arid pastoral areas, comprising a building body, a diversion component, a filtering component and a water collecting tank. The building body includes a building wall. The diversion component includes a diversion plate and a spring. The upper connection surface of the diversion plate is rotatably connected to the building wall. The two ends of the spring are respectively connected to the lower connection surface of the diversion plate and the building wall, so that the diversion plate is inclined downward relative to the building wall for rainwater diversion. The filtering component includes a filtering box body, which is fixedly connected to the building wall, and the upper end surface of the filtering box body is arranged below the lower end surface of the diversion plate for rainwater filtration. The water collecting tank is arranged below the filtering box body for rainwater collection;

[0007] The filter box body is connected with a movable filter screen and two fixed filter screens. The two fixed filter screens are detachably connected to the upper and lower end faces of the filter box body. The movable filter screen is rotatably arranged between the two fixed filter screens, and the movable filter screen is connected to the guide plate through a linkage assembly.

[0008] Further, the linkage assembly includes a first connecting rod, a second connecting rod and a linkage plate. The first connecting rod is connected to the guide plate. Two ends of the second connecting rod are respectively rotatably connected to one end of the linkage plate and one end of the first connecting rod far away from the guide plate. The middle part of the linkage plate is rotatably connected to the filter box body, and the movable filter screen is fixedly connected to the linkage plate.

[0009] Further, there are three movable filter screens. The three movable filter screens are uniformly arranged along the axial direction of the linkage plate. A pair of oppositely arranged arc-shaped grooves are formed in the side wall of the filter box body. Connecting shafts of the two movable filter screens on both sides are respectively slidably connected to the pair of arc-shaped grooves.

[0010] Further, the diameter of the filter holes of the fixed filter screen is larger than that of the movable filter screen. The included angle of the arc-shaped surface of the arc-shaped groove is 90°.

[0011] Further, a connecting block is fixedly connected to the building wall body, a connecting frame is fixedly connected to the guide plate, and the connecting block and the connecting frame are connected through a telescopic rod.

[0012] Further, two ends of the spring are respectively connected to the guide plate and the building wall body through universal ball assemblies.

[0013] Further, a plurality of flow guide grooves are uniformly formed in the upper surface of the guide plate.

[0014] Further, a through hole is formed in the building wall body, and a baffle plate for opening and / or closing the through hole is rotatably connected to the building wall body.

[0015] Further, the through hole is arranged between the upper connecting surface of the guide plate and the upper end surface of the filter box body.

[0016] The beneficial effects of the technical solution are:

[0017] 1. A rainwater recycling device for green buildings in arid pastoral areas provided by the present invention is provided with a diversion component and a filtration component to divert and filter rainwater respectively. The upper connecting surface of the diversion plate of the diversion component is rotatably connected to the building wall, and both ends of the spring are connected to the lower connecting surface of the diversion plate and the building wall respectively, so that the diversion plate is inclined downward relative to the building wall to divert rainwater. When the amount of rainwater is large, the impact pressure of the rainwater on the diversion plate is greater, and the compression amount of the spring is also greater, making the diversion plate more inclined downward to ensure the diversion of rainwater and prevent rainwater backflow. When the rainwater is small, the impact pressure of the rainwater on the diversion plate is smaller, and the compression amount of the spring is also smaller, making the diversion plate more inclined to be horizontal, and the coverage area of the diversion plate is larger to ensure the rainwater recycling amount. The filtration box body of the filtration component is arranged below the diversion plate for filtering rainwater, and the water collection tank is arranged below the filtration box body for collecting rainwater.

[0018] 2.

The first connecting rod of the linkage component is connected to the diversion plate, both ends of the second connecting rod of the linkage component are rotatably connected to one end of the linkage plate and the end of the first connecting rod far away from the diversion plate respectively, the middle part of the linkage plate of the linkage component is rotatably connected to the filtration box body, and the movable filter screen is fixedly connected to the linkage plate. When the angle of the diversion plate changes, the linkage plate rotates relative to the filtration box body under the action of the first connecting rod and the second connecting rod, so that the angle of the movable filter screen relative to the filtration box body also changes accordingly. Specifically, when the amount of rainwater is large, the diversion plate is more inclined downward, and the movable filter screen is also inclined downward relative to the filtration box body, reducing the filtering effect on rainwater but increasing the conduction effect on rainwater. On the contrary, when the amount of rainwater is small, the diversion plate is more inclined to be horizontal, and the movable filter screen is also inclined to be horizontal relative to the filtration box body, reducing the conduction effect on rainwater but increasing the filtering effect on rainwater, so as to adapt to different usage requirements (when the rainwater volume is large, give priority to ensuring the conduction effect and prevent rainwater backflow; when the rainwater volume is small, give priority to ensuring the filtering effect).

[0019] 3. The green building rainwater recycling device for arid pastoral areas provided by the present invention is provided with three movable filters, which can multiply the filtering effect on rainwater; a pair of oppositely arranged arc-shaped grooves are opened on the side wall of the filtering box body, and the connecting shafts of the two movable filters on both sides are respectively slidably connected with the pair of arc-shaped grooves, so that during the process of the guide plate rotating and driving the movable filter to rotate, the connecting shaft of the movable filter slides in the arc-shaped groove, and the movement of the two is guided and limited to ensure the stability and functionality of the rotation process; the pore diameter of the fixed filter is larger than that of the movable filter to achieve hierarchical filtration of rainwater; the included angle of the arc surface of the arc-shaped groove is set to 90°, so that the rotation range of the movable filter is 90°; specifically, when the guide plate does not rotate, the movable filter does not rotate either, and the rotation angle is 0. At this time, the movable filter is horizontally arranged relative to the filtering box body, and the filtering effect on rainwater is the best; when the guide plate rotates at the maximum angle, the rotation angle of the movable filter is also the largest, and the rotation angle is 90°. At this time, the movable filter is vertically arranged relative to the filtering box body, and the rainwater conduction effect is the best.

[0032] The specific implementation process is as follows:

[0033] When the rainwater recovery device is used to recover rainwater, the rainwater flowing down from the eaves of the building body 10 drips onto the guide plate 21 of the guide component 20 and flows along the guide plate 21 into the filtering box body 31 of the filtering component 30. The fixed filter mesh 32 and the movable filter mesh 34 connected to the filtering box body 31 filter the rainwater inside; the filtered rainwater is collected in the water collecting tank 40.

[0034] Among them, the upper connecting surface of the flow guiding plate 21 of the flow guiding assembly 20 is rotatably connected to the building wall 11, and both ends of the spring 25 are respectively connected to the lower connecting surface of the flow guiding plate 21 and the building wall 11. When the amount of rainwater is large, the impact pressure of the rainwater on the flow guiding plate 21 is greater, and the compression amount of the spring 25 is also greater, causing the flow guiding plate 21 to incline more downward to ensure the diversion of rainwater and prevent rainwater from flowing back; when the rainwater is small, the impact pressure of the rainwater on the flow guiding plate 21 is smaller, and the compression amount of the spring 25 is also smaller, causing the flow guiding plate 21 to tend to be more horizontal, and the coverage area of the flow guiding plate 21 is larger to ensure the rainwater recovery amount; a connecting block 24 is connected to the building wall 11, a connecting frame 23 is connected to the flow guiding plate 21, and the connecting block 24 and the connecting frame 23 are connected by a telescopic rod 26, which can not only ensure the self-adjustment (angle) function of the flow guiding plate 21, but also facilitate the installation and debugging of the function of the flow guiding plate 21; both ends of the spring 25 are connected to the flow guiding plate 21 and the building wall 11 through a universal ball assembly, so that the angle between the spring 25 and the flow guiding plate 21 and / or the building wall 11 can be adjusted to ensure the smoothness of the spring 25 during the compression process and improve the sensitivity of the angle self-adjustment of the flow guiding plate 21; a plurality of flow guiding grooves 22 are uniformly formed on the upper surface of the flow guiding plate 21 to improve the flow guiding effect of rainwater.

[0035] The filter box body 31 connects and fixes the fixed filter screen 32 and the movable filter screen 34, and both filter the rainwater flowing into the filter box body 31 by the flow guide plate 21; the movable filter screen 34 is connected to the flow guide plate 21 through a linkage component. When the angle of the flow guide plate 21 changes, the angle of the movable filter screen 34 relative to the filter box body 31 also changes accordingly. Specifically, when the amount of rainwater is large, the flow guide plate 21 tilts more downward, and the movable filter screen 34 also tilts downward relative to the filter box body 31. The filtering effect on the rainwater decreases, but the guiding effect on the rainwater increases; on the contrary, when the amount of rainwater is small, the flow guide plate 21 tends to be horizontal, and the movable filter screen 34 also tends to be horizontal relative to the filter box body 31. The guiding effect on the rainwater decreases, but the filtering effect on the rainwater increases; to adapt to different usage requirements (when the rainwater volume is large, prioritize ensuring the guiding effect to avoid rainwater backflow; when the rainwater volume is small, prioritize ensuring the filtering effect); three movable filter screens 34 are provided to multiply the filtering effect on the rainwater; a pair of oppositely arranged arc-shaped grooves 33 are opened on the side wall of the filter box body 31, and the connecting shafts of the two movable filter screens 34 on both sides are respectively slidably connected to the pair of arc-shaped grooves 33, so that during the process of the flow guide plate 21 rotating and driving the movable filter screen 34 to rotate, the connecting shaft of the movable filter screen 34 slides in the arc-shaped groove 33, and the movement of the two is guided and limited to ensure the stability and functionality of the rotation process; the pore diameter of the fixed filter screen 32 is larger than the pore diameter of the movable filter screen 34 to achieve hierarchical filtration of the rainwater; the included angle of the arc-shaped surface of the arc-shaped groove 33 is set to 90°, so that the rotation range of the movable filter screen 34 is 90°; when the flow guide plate 21 does not rotate, the movable filter screen 34 also does not rotate, and the rotation angle is 0. At this time, the movable filter screen 34 is horizontally arranged relative to the filter box body 31, and the filtering effect on the rainwater is the best; when the flow guide plate 21 rotates at the maximum angle, the rotation angle of the movable filter screen 34 is also the largest, and the rotation angle is 90°. At this time, the movable filter screen 34 is vertically arranged relative to the filter box body 31, and the guiding effect on the rainwater is the best.

[0036] A through hole 12 is opened on the building wall 11, and a shutter 13 for opening and / or closing the through hole 12 is rotatably connected to the building wall 11.
