In the present invention, by setting a shielding structure, on sunny days, the water collection component is located at a high place, and the solar panel collects solar energy upwards. At this time, the green plants in the green plant trough can be exposed to sunlight. On rainy days, the hydraulic cylinder will drive the lower support structure and the upper support structure to move downward synchronously, and drive the shaft to rotate under the transmission of the tooth plate and the third gear, and then drive the driving gear to rotate, and then drive the rain shield to rotate under the transmission of the driven gear, so that rainwater enters the water collection chamber from the rain inlet pipe under the action of gravity for storage, thereby avoiding water accumulation in the green plant trough and causing the roots of the green plants to rot.

[0017] 2. In the present invention, by setting a rain inlet structure, on rainy days, the rain shield rotates, so that the first gear at the front end drives the rotating drum to rotate through the second gear and drives the fixed rod to rotate synchronously, and then drives the transmission rod to move backward through the spiral groove, and pulls the rain shield block under the action of the hinged rod. Under the restriction of the limit groove and the limit block, the rain shield block will rotate to open the rain inlet, so that rainwater can enter the water collecting chamber for storage through the rain inlet, avoiding long-term opening on sunny days, which will cause too much dust or insects to enter the water collecting chamber.

This is a prior art and will not be described in detail here; A plurality of shielding structures 24 are regularly arranged between the lower support structure 22 and the upper support structure 23. The shielding structure 24 includes a rain shield 241 and a solar panel 242 embedded on the top surface of the rain shield 241. When it is sunny, the water collection component 2 is located at a higher position. At this time, the solar panel 242 can absorb solar energy to power the building. At the same time, the water collection component 2 at a higher position will not block the green plants in the green plant trough 11 from receiving sunlight; Auxiliary frames 12 are symmetrically arranged on the left and right side walls of the roof 1 near the rear side, and the upper support structure 23 is arranged between the two auxiliary frames 12. A slide groove 121 is arranged in the middle of the inner wall of the auxiliary frame 12, and a tooth plate 122 is fixed to the top of the rear side groove wall of the slide groove 121. When it rains, the hydraulic cylinder 21 will drive the lower support structure 22 and the upper support structure 23 to move downward synchronously, and since the tooth plate 122 is meshed with the corresponding third gear 28, the third gear 28 will rotate counterclockwise; The upper bracket structure 23 includes an upper bracket 231 and a mounting cavity 232 inside the upper bracket 231. The mounting cavity 232 is provided with a left and right horizontal shaft rod 26. The two ends of the shaft rod 26 pass through the corresponding side walls of the mounting cavity 232 and the end of the shaft rod 26 is coaxially fixedly connected with a third gear 28. The third gear 28 extends into the corresponding side slide groove 121. A driven tooth 244 is fixed to the middle of the rear side wall of the rain shield 241. A driving tooth 27 is coaxially fixed at the position corresponding to the side wall of the shaft rod 26 and the driven tooth 244. The driven tooth 244 passes through the front side wall of the mounting cavity 232 and meshes with the corresponding driving tooth 27. When the third gear 28 rotates, it will drive the shaft rod 26 to rotate. Then, under the transmission of the driving tooth 27 and the driven tooth 244, the rain shield 241 will be driven to rotate 180° counterclockwise, so that the bottom surface of the rain shield 241 faces upward. The lower support structure 22 includes a lower support 221 and a water collecting chamber 222 arranged in the lower support 221. The front side wall of the water collecting chamber 222 is provided with a plurality of rain inlet structures 25 for controlling the flow of rainwater. Under the action of gravity, rainwater will be enriched in the rain inlet structure 25, and then enter the water collecting chamber 222 through the rain inlet structure 25 to store rainwater.

[0022] Specifically, Figure 1-Figure 5 As shown, the bottom surface of the hydraulic cylinder 21 is fixed on the top surface of the roof 1 near the four corners, and the telescopic end is fixed at the bottom corners of the corresponding lower bracket 221 and the upper bracket 231. There is no gap between the two adjacent rain shields 241 to prevent rainwater from falling directly into the green plant groove 11 between the rain shields 241, resulting in serious water accumulation in the green plant groove 11, which may easily cause the roof 1 to leak and the roots of the green plants to rot. The rear end thickness of the bottom surface of the rain shield 241 is large and the front end thickness is small. After rainwater falls into the rain shield 241, the inclined bottom surface will cause the rainwater to flow to the side of the lower support structure 22. The bottom surface of the rain shield 241 is symmetrically provided with water collecting plates 245 near the front end. The depression between the two water collecting plates 245 corresponds to the position of the rain inlet structure 25. By setting the water collecting plates 245, the rainwater is concentrated at the rain inlet structure 25 to avoid rainwater residue.

[0023] Furthermore, if Figure 2As shown in FIG7 , a plurality of regularly arranged overflow pipes 223 are provided in the water collecting chamber 222, the bottom end of the overflow pipe 223 passes through the bottom surface of the water collecting chamber 222 and the bottom end of the overflow pipe 223 is connected to a water discharge assembly 3, the water discharge assembly 3 comprises a bellows 32 whose top end is connected to the bottom end of the overflow pipe 223 and a curved pipe 31 connected to the bottom end of the bellows 32, the curved pipe 31 is fixed to the front side wall of the roof 1, and by arranging the overflow pipe 223, when the liquid level in the water collecting chamber 222 is higher than the height of the overflow pipe 223 due to excessive rainwater, the excessive rainwater will flow from the overflow pipe 223 into the bellows 32 and flow out from the curved pipe 31, so as to avoid the water collecting chamber 222 being full of rainwater and being unable to drain continuously thereafter; In addition, the height of the overflow pipe 223 is greater than three quarters of the height of the water collecting chamber 222. The bottom surface of the water collecting chamber 222 is connected to a plurality of regularly arranged nozzles 4, which are arranged toward the green plant groove 11. The distance between the nozzle 4 and the bottom surface of the lower bracket 221 is greater than the left and right width of the rain shield 241. By arranging the nozzle 4, the controller can be used to control the nozzle 4 to spray water regularly on sunny days to prevent the green plant groove 11 from being too dry and causing the death of green plants. In addition, as shown in FIGS. 7 to 12 , the rain inlet structure 25 includes a rain inlet pipe 251, a plurality of rain inlets 252 regularly distributed in an annular shape on the outer end wall of the rain inlet pipe 251, and a movable mechanism 253 for controlling the opening and closing of the rain inlets 252. The inner end of the rain inlet pipe 251 passes through the front side wall of the water collecting cavity 222 and is connected to the inside of the water collecting cavity 222. Rainwater can enter the rain inlet pipe 251 through the rain inlet 252 and then flow into the water collecting cavity 222. Furthermore, a hollow rotating drum 255 is provided at the rear end of the rain inlet pipe 251, and a second gear 256 is coaxially fixed to the outer wall of the rotating drum 255 near the rear end, and a first gear 243 is fixed to the middle of the front side wall of the rain shield 241, and the first gear 243 is arranged inside the water collecting chamber 222 and meshes with the corresponding second gear 256. A clamping groove 2511 is provided on the rear end face of the rain inlet pipe 251, and a clamping ring 257 is fixed to the front end face of the rotating drum 255. The clamping ring 257 and the clamping groove 2511 can support the rotating drum 255, and the clamping ring 257 is arranged in the corresponding clamping groove 2511 and the clamping ring 257 can freely rotate the fixing rod 258. When shielding rain, the rain shield 241 rotates counterclockwise, and the first gear 243 at the front end drives the second gear 256 to rotate clockwise, thereby driving the rotating drum 255 to rotate so that the fixing rod 258 rotates synchronously; Specifically, the movable mechanism 253 includes a plurality of rain shielding blocks 2531 arranged one by one inside the rain inlet 252 and limit blocks 2532 fixed on the left and right sides of the rain shielding blocks 2531 near the outer ends. The rain shielding blocks 2531 are adapted to the size and shape of the rain inlet 252. The side walls of the rain inlet 252 are provided with limit grooves 2521. The limit blocks 2532 are arranged in the corresponding limit grooves 2521 and can slide up and down. The rain shielding blocks 2531 can block the rain inlet 252 on sunny days to prevent excessive dust from entering the water collection chamber 222 due to long-term opening on sunny days. In addition, a transmission rod 254 is provided inside the rain inlet pipe 251, and a plurality of hinged rods 2533 corresponding to the rain shield blocks 2531 are provided on the side wall of the transmission rod 254 near the front end. The two ends of the hinged rod 2533 are respectively hinged to the corresponding rain shield blocks 2531 and the side wall of the transmission rod 254 near the front end. A fixing rod 258 is symmetrically provided inside the rotating drum 255, and two sets of spiral grooves 2541 are provided on the side wall of the transmission rod 254. The outer end of the fixing rod 258 is embedded in the corresponding spiral groove 2541 in a hemispherical shape. Since the front end of the transmission rod 254 is hinged, The connecting rod 2533 is connected to the rain shield block 2531, and the rain shield block 2531 is restricted by the clamping ring 257 and the clamping groove 2511, so that the transmission rod 254 does not rotate. When the fixing rod 258 rotates clockwise with the rotating drum 255, the transmission rod 254 moves backward under the action of the spiral groove 2541, thereby driving the top of the rain shield block 2531 to move radially along the clamping groove 2511 toward the rain inlet pipe 251 to open the rain inlet 252, so that rainwater flows through the rain inlet pipe 251 through the rotating drum 255 and enters the water collecting chamber 222; The environmentally friendly building roof leak prevention and drainage method of the present invention comprises the following steps: S1, on sunny days, the water collection assembly 2 is located at a high place, and the solar panel 242 faces upward to collect solar energy, while the green plants in the green plant groove 11 can be exposed to sunlight; S2. When it rains, the hydraulic cylinder 21 is started to drive the lower support structure 22 and the upper support structure 23 to move downward synchronously, and the shaft 26 is driven to rotate under the transmission of the tooth plate 122 and the third gear 28, thereby driving the driving gear 27 to rotate, and then driving the rain shield 241 to rotate 180° under the transmission of the driven gear 244; S3. When the rain shield 241 rotates, the first gear 243 at the front end drives the rotating drum 255 to rotate through the second gear 256, so that the fixing rod 258 rotates synchronously, and then drives the transmission rod 254 to move backward through the spiral groove 2541, and pulls the rain shield block 2531 under the action of the hinge rod 2533. Under the restriction of the limit groove 2521 and the limit block 2532, the rain shield block 2531 rotates to open the rain inlet 252; S4, after the rain shield 241 rotates 180 degrees, the rain falls on the bottom surface of the rain shield 241, flows to the side of the lower bracket 221 under the action of gravity, and gathers at the rain inlet structure 25 under the action of the water collecting plate 245, so that the rain can enter the water collecting chamber 222 through the rain inlet 252 for storage; S5. When the stored rainwater is higher than the overflow pipe 223, the rainwater will enter the corrugated pipe 32 through the overflow pipe 223 and flow out from the curved pipe 31 to the bottom of the building.
