[0021] Example 1: Please refer to Figure 1-Figure 5 As shown, the existing energy-saving buildings with rainwater collection and reuse functions are inconvenient to rotate and collect rainwater in different time periods, resulting in excessive impurities in the collected rainwater and affecting subsequent processing and use. In order to solve this technical problem, the present embodiment discloses the following technical content; an energy-saving building with rainwater collection and reuse functions, including a wall 1 and a roof 2, a collecting seat 3 is fixedly installed at the edge of the roof 2, and a first collecting trough 4 and a second collecting trough 5 are respectively opened on the inner side of the collecting seat 3, and a floating component is arranged on the inner side of the second collecting trough 5, a cover plate 13 is elastically rotatably installed on the upper end of the collecting seat 3, and a locking component for limiting the cover plate 13 is also installed on the collecting seat 3, and the locking component releases the limit on the cover plate 13 when the floating component floats, and drives the cover plate 13 to rotate and open when the floating component floats; a filter plate 17 is lifted and lowered on the inner side of the first collecting trough 4 of the collecting seat 3, and both ends of the filter plate 17 pass through the holes opened in the collecting seat 3.

[0022] The second collecting trough 5 collects rainwater flowing down from the roof 2, and the floating assembly includes a first floating plate 6 which is lifted and lowered inside the second collecting trough 5, and the first floating plate 6 is evenly provided with through-hole structures. At the same time, the first floating plate 6 will float under the action of rainwater, and a drainage hole 15 connected to the second collecting trough 5 is provided on the collecting seat 3. The rainwater collection rate of the second collecting trough 5 is greater than the drainage rate of the drainage hole 15.

[0023] The upper surface of the first floating plate 6 is symmetrically fixed with guide pillars 7 , and a second floating plate 8 is lifted and installed through the guide pillars 7 , and a vertically arranged top rod 9 is fixed and installed on the top of the second floating plate 8 .

[0024] The locking assembly includes a limiting column 10 fixedly mounted on the collecting seat 3, and a locking block 11 is telescopically and slidably mounted on the limiting column 10, and a first spring 12 is connected between the locking block 11 and the collecting seat 3, and the lower surface of the left end of the locking block 11 is attached to the right end of the cover plate 13 to limit the cover plate 13, and the upper and lower surfaces of the locking block 11 are both provided with inclined structures, and the cover plate 13 contacts the inclined surface of the upper surface of the locking block 11 during the rotation and downward movement to push the locking block 11 to slide elastically, and the top rod 9 on the second floating plate 8 contacts the inclined surface of the lower surface of the locking block 11 during the floating process to push the locking block 11 to slide elastically.

[0025] A reel 14 is fixedly mounted on the outer side of the shaft of the cover plate 13 , and a pull rope 16 is wound around the outer side of the reel 14 . The pull rope 16 passes through the drainage hole 15 and is fixedly connected to the outer side of the first floating plate 6 .

[0026] The filter plate 17 is arranged in an inverted V-shaped structure, and a second spring 18 is connected between the filter plate 17 and the collecting seat 3, and a first magnetic block 1301 is fixedly installed on the lower surface of the cover plate 13, and a second magnetic block 1701 is fixedly installed on the upper surface of the filter plate 17, the magnetic poles of the opposite surfaces of the first magnetic block 1301 and the second magnetic block 1701 are opposite, and when the cover plate 13 is closed, the filter plate 17 is elastically moved upward under the magnetic adsorption of the first magnetic block 1301 and the second magnetic block 1701.

[0028] By adopting the above technical solution, when it rains, the second collecting trough 5 can collect rainwater, so that the water level in the second collecting trough 5 rises, and at this time the first floating plate 6 and the second floating plate 8 will float up. When the pull rope 16 tightens the first floating plate 6, the first floating plate 6 stops floating up, while the second floating plate 8 continues to float up. At this time, the top rod 9 on the top of the second floating plate 8 will contact the inclined surface of the lower surface of the locking block 11, thereby pushing the locking block 11 to slide and adjust on the limiting column 10, thereby releasing the limit on the cover plate 13. At this time, the first floating plate 6 will float up under the buoyancy. Under the action of the pull rope 16, the wind-up wheel 14 is pulled to rotate, thereby driving the wind-up wheel 14 to rotate and open. At this time, the first collecting trough 4 can rotationally collect the middle rainwater and the rear rainwater to avoid collecting the front rainwater containing too many impurities. As the cover plate 13 is rotated and opened, the first magnetic block 1301 and the second magnetic block 1701 both lose their magnetic effect, so that the filter plate 17 is shaken under the elastic force of the second spring 18, thereby realizing automatic clearing and discharging impurities through the holes opened on the collecting seat 3.

[0029] Embodiment 2: The technical content disclosed in this embodiment is a further improvement based on the above embodiment 1. The existing energy-saving buildings with rainwater collection and reuse function are inconvenient to use the collected rainwater to adjust the building insulation effect. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 6-Figure 11As shown; a heat exchanger 20 is evenly embedded and installed on the inner side of the wall 1, and a partition 21 is fixedly installed on the inner side of the upper part of the heat exchanger 20, and water inlet holes 2101 are evenly opened on the partition 21, and a water storage cylinder 22 is evenly fixedly installed on the lower surface of the partition 21, and a drainage pipe 23 is fixedly installed on the inner side of the water storage cylinder 22, and the lower end of the drainage pipe 23 passes through the lower end of the water storage cylinder 22, and a heat exchange cylinder 24 is rotatably arranged on the outer side of the water storage cylinder 22, and a collecting bin 26 is connected to the bottom of the lowest heat exchanger 20 through a pipeline, and the collecting bin 26 is fixedly installed on the wall 1, and the collecting bin 26 is connected to an external water storage barrel through a pipeline.

[0030] The collecting seat 3 and the upper part of the uppermost heat exchange element 20 are connected by a pipe, and the water inlet hole 2101 opened on the partition 21 and the position of the water storage cylinder 22 are set correspondingly, and the water storage cylinder 22 and the drainage pipe 23 are coaxially arranged. At the same time, after the water storage cylinder 22 is filled with water, excess rainwater is discharged through the drainage pipe 23, and the upper and lower adjacent heat exchange elements 20 are connected by a pipe.

[0031] The heat exchange tube 24 is fittedly sleeved on the outside of the water storage tube 22, and the heat exchange tube 24 is made of symmetrically arranged heat insulating material and heat conductive material, and the outer diameter of the heat exchange tube 24 is greater than the thickness of the heat exchange element 20. At the same time, the outer wall of the heat exchange tube 24 protrudes from the heat exchange element 20 through the holes opened on the heat exchange element 20, and an adjustment piece 25 made of memory metal is connected between the inner wall of the heat exchange element 20 and the heat exchange tube 24, and the adjustment piece 25 is bent and straightened under the action of temperature.

[0032] By adopting the above technical scheme, the rainwater collected in the first collecting tank 4 will enter the upper part of the heat exchanger 20 through the pipe. At this time, the rainwater will enter the water storage cylinder 22 at the corresponding position through the water inlet hole 2101. When the water storage cylinder 22 is full of rainwater, it will be discharged to the inner side of the heat exchanger 20 through the water storage cylinder 22, and flow into the upper part of the heat exchanger 20 located below through the pipe, so as to fill the water storage cylinder 22 in each heat exchanger 20. When the outside temperature is too high, the heat conductive material of the heat exchange cylinder 24 will face the outside of the building, so as to assist the rainwater in the water storage cylinder 22 to absorb heat. When the outside temperature is low, the adjustment piece 25 made of memory metal material will deform under the influence of temperature, so as to drive the heat exchange cylinder 24 to rotate and adjust. At this time, the heat conductive material part of the heat exchange cylinder 24 is attached to the inner side of the wall 1, so that the heat accumulated by the rainwater can be transferred to the wall 1, so as to achieve indoor insulation of the building, thereby assisting in adjusting the indoor temperature and further improving the energy saving effect.
