[0024] In the following description, embodiments of the rainwater harvesting structure for sloping building roofs of the present invention will be described with reference to the accompanying drawings. Example 1
[0025] Figure 1-6 This invention illustrates a rainwater collection structure for a sloping building roof according to an embodiment of the present invention. The structure includes: a support frame 2 bolted to the front of the sloping building 1; a limiting support groove 3 bolted to the front of the support frame 2; a positioning connecting plate 4 slidably connected to the inner cavity of the limiting support groove 3; L-shaped movable strips 5 slidably connected to the left and right sides of the inner cavity of the limiting support groove 3; spring plates 6 welded between the two L-shaped movable strips 5 and the inner cavity of the limiting support groove 3; a first trapezoidal head 7 fixedly connected to the opposite side of each of the two L-shaped movable strips 5; and second trapezoidal heads 8 fixedly connected to the left and right sides of the positioning connecting plate 4. The surface of the second trapezoidal head 8 slidably connects to the surface of the first trapezoidal head 7. The support frame 2 is positioned close to... At the top of the sloping building 1, a supporting connecting plate 9 is welded to the front side of the top of the positioning connecting plate 4. A rainwater inlet groove 10 is fixedly connected to the front side of the supporting connecting plate 9. A vertical limiting piece 11 is fixedly connected to the inner cavity of the limiting supporting groove 3. A vertical guide groove 12 is opened on the rear side of the positioning connecting plate 4. The surface of the vertical limiting piece 11 is slidably connected to the inner cavity of the vertical guide groove 12. Through the cooperation of the vertical limiting piece 11 and the vertical guide groove 12, the positioning connecting plate 4 can obtain a vertical guiding limiting force during the sliding process in the inner cavity of the limiting supporting groove 3. This enables the positioning connecting plate 4 to maintain vertical sliding during sliding and makes the positioning connecting plate 4 more stable when supporting the rainwater inlet groove 10. Example 2
[0026] Figure 1-6This invention illustrates a rainwater collection structure for a sloping building roof according to an embodiment of the present invention. The structure includes: a support frame 2 bolted to the front of the sloping building 1; a limiting support groove 3 bolted to the front of the support frame 2; a positioning connecting plate 4 slidably connected to the inner cavity of the limiting support groove 3; L-shaped movable strips 5 slidably connected to the left and right sides of the inner cavity of the limiting support groove 3; spring plates 6 welded between the two L-shaped movable strips 5 and the inner cavity of the limiting support groove 3; a first trapezoidal head 7 fixedly connected to the opposite side of each of the two L-shaped movable strips 5; a second trapezoidal head 8 fixedly connected to the left and right sides of the positioning connecting plate 4; the surface of the second trapezoidal head 8 slidably connected to the surface of the first trapezoidal head 7; and two limiting guide strips 13 fixedly connected to the bottom of the inner cavity of the limiting support groove 3. Each of the L-shaped movable strips 5 has a guide groove at its bottom. The surface of the guide strip 13 is slidably connected to the inner cavity of the guide groove. By setting the guide strip 13, when the L-shaped movable strip 5 slides in the inner cavity of the guide support groove 3, the sliding direction of the L-shaped movable strip 5 is guided by a linear translational force, which can keep the L-shaped movable strip 5 sliding in a straight line and prevent the L-shaped movable strip 5 from deviating. A rubber pad strip 14 is fixedly connected to the bottom of the inner cavity of the guide support groove 3. Rainwater collection boxes 15 are fixedly connected to the left and right sides of the sloping building 1 by bolts. A connecting pipe 16 connects the bottom of the rainwater inlet trough 10 and the rainwater collection box 15. A protective cover plate 17 is rotatably connected to the top of the rainwater collection box 15. An expansion cavity receiving groove 18 is fixedly connected to the top of the rainwater inlet trough 10.
[0027] Working Principle: In use, the user fixes the support bracket 2 together with the limiting support groove 3 to the main body of the sloping building 1. Then, the positioning connecting plate 4 is fixedly connected to the rainwater inlet groove 10 via the support connecting plate 9. Subsequently, the positioning connecting plate 4 is inserted into the inner cavity of the limiting support groove 3 from top to bottom. During the sliding process of the positioning connecting plate 4 within the inner cavity of the limiting support groove 3, the second trapezoidal heads 8 fixed on the left and right sides of the positioning connecting plate 4 can cooperate with the first trapezoidal heads 7, allowing the surface of the positioning connecting plate to... In this special shape, the two L-shaped movable bars 5 are pushed, causing them to slide back to back. Once the second trapezoidal head 8 is at the bottom of the first trapezoidal head 7, the rebound force of the spring plate 6 can push the L-shaped movable bars 5 back to their original position. This allows the L-shaped movable bars 5 and the first trapezoidal head 7 to restrict the positions of the positioning connecting plate 4 and the second trapezoidal head 8, thereby fixing the position of the rainwater flowing into the trough 10. This makes the installation of the rainwater collection device more convenient and speeds up the installation process.
[0028] In summary, this rainwater collection structure for sloping roofs, by inserting the positioning connecting plate 4 into the inner cavity of the limiting support groove 3 from top to bottom, and with the cooperation of the L-shaped movable strip 5, spring plate 6, first trapezoidal head 7 and second trapezoidal head 8, fixes the position where rainwater flows into the groove 10, thus making the installation of the rainwater collection device more convenient and speeding up the installation process.
