At present, a siphon rainwater drainage system is widely applied to a planting roof and a planting roof, a layer of waterproof plate is firstly paved on a building, a garage or a road surface, then water collecting plates are paved on the waterproof plate, and a drainage channel is connected between the water collecting plates. Then a layer of geotextile is laid above the water collecting plate and the water drainage tank, and greening soil is backfilled at the top of the geotextile. Penetrating water in the soil penetrates through the geotextile to enter the water collecting plate, then flows into the drainage grooves through the water inlets on two sides of the drainage grooves, and finally enters the reservoir from the drainage grooves. This system mainly utilizes hydrocone type water drainage tank to produce the siphon effect, collects the infiltration water to the cistern in, irrigates to roofing afforestation or ground vegetation and sprays, when realizing the plumbing, satisfies energy-concerving and environment-protective requirement. The existing drainage channels are mainly divided into a straight-through drainage channel, a three-way drainage channel, a four-way drainage channel and the like according to types, wherein the three-way drainage channel or the four-way drainage channel is used for splicing and connecting the straight-through drainage channel.

In the prior art, the straight-through drainage channel is a rigid drainage blind channel, and the connection angle of the three-way drainage channel or the four-way drainage channel is fixed (generally 90 °), so that the straight-through drainage channel can only be arranged on the building roof in a fixed form (generally in a cross-wise and longitudinal staggered chessboard layout pattern). Because the plane shape of the building roof is often irregular, irregular and variable, on one hand, the rigid straight-through drainage channel is difficult to completely cover the irregular position (such as the curve edge) of the building roof; on the other hand, various connection angles exist among the through drainage grooves optimally arranged according to the shape of the building roof, the limited specifications of the three-way drainage grooves or the four-way drainage grooves are difficult to meet, and the problem that the through drainage grooves are difficult to connect exists. Therefore, the existing drainage channel has the problem of single arrangement shape and connection form, and is difficult to meet the requirements of completely covering the building roof and quickly constructing.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provides a flexible hinge drainage channel which is used for solving the problem that the drainage channel is single in arrangement shape and connection form, achieving the effects that the drainage channels are arranged in any shape and at any position and are connected at any angle, and further meeting the requirements of completely covering a building roof and quickly constructing the drainage channel.

Detailed Description

The drawings are only for purposes of illustration and are not to be construed as limiting the utility model. For a better understanding of the following embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

Example 1

As shown in fig. 1 and 2, the present embodiment is a flexible hinge drainage channel 100, which includes a plurality of sections of drainage channel units 10 and a drainage channel adapter unit 50; two ends of each section of the drainage groove unit 10 are provided with connecting structures 31; the drainage channel units 10 are connected with each other through a connecting structure 31 and can rotate with each other; one end of the drain tank switching unit 50 is provided with a connecting structure 31, and the other end is provided with an assembling structure 51 for connecting with other types of drain tanks; after the plurality of sections of the drainage channel units 10 are connected one by one in sequence, the two ends of the drainage channel units are respectively connected with the drainage channel switching units 50 to form the flexible hinge drainage channel 100.

The embodiment divides the straight-through drainage channel 210 into a plurality of sections of drainage channel units 10 on the basis of the existing straight-through drainage channel through a bionic design. The two ends of each drainage channel unit 10 are provided with connecting structures 31, and after the drainage channel units 10 are connected in pairs in sequence, the two ends are respectively connected with the drainage channel switching unit 50 to assemble the flexible hinge drainage channel 100. The flexible hinge drain channel is connectable at both ends to an existing drain channel by means of an assembly 51. On one hand, since any two drainage channel units 10 can rotate mutually within a certain angle range through the connecting structure 31, the whole drainage channel composed of a plurality of drainage channel units 10 has certain flexibility relative to the existing through drainage channel 210, and can be adjusted to a proper shape according to the specific shape or position of the building roof. Specifically, the flexible hinge drain 100 may be adjusted to a C-shape, an S-shape, or the like as a whole. Of course, the flexible hinge gutter can also be adjusted to any irregular shape at will in order to avoid building structures on the building roof. In addition, the length specifications of the flexible hinge drain are flexible compared to the limited length specifications of the existing straight through drain 210. As the number of the drain tank units 10 connected one by one in sequence is gradually increased or decreased, the overall length of the flexible hinge drain tank is gradually increased or decreased. The length of the flexible hinge drainage channel is freely increased or decreased by taking a section of the drainage channel unit 10 as a unit until the requirement of connection between the drainage channels is met. Therefore, the flexible hinge drainage groove solves the problem that the drainage groove is single in arrangement shape, and therefore the effect that the drainage groove is arranged in any shape, any position and any length is achieved. On the other hand, based on the flexibility of the drainage channel, the description will be continued by taking a building roof partially in a triangular shape as an example. According to the triangular shape of the building roof, one preferred arrangement of the straight-through drainage channel 210 is as follows: the three sides of the triangle are respectively taken as the reference, and multiple annular arrangement is carried out by a plurality of similar triangles from the outer side to the center according to a certain interval. In a preferred arrangement, the straight-through drainage channels 210 are connected at three triangular corners. Because the corner is not necessarily 90 degrees, current general tee bend water drainage tank or four-way water drainage tank will not directly use. The flexible hinge gutter 100 can adjust the rotation angle between its respective gutter units 10 so as to obtain an arbitrary connection angle at both ends, which corresponds to a gutter connector for connecting two through gutters 210 arranged at an arbitrary angle. Therefore, the flexible hinge water draining groove solves the problem that the water draining groove is single in connection form, and the effect of connection between the water draining grooves at any angle is achieved.

In the embodiment, the flexible drainage channels and the flexible connection between the drainage channels are realized through the plurality of sections of drainage channel units 10, so that the drainage channels can adopt an irregular and better arrangement scheme according to the specific shape and the construction requirement of the building roof, and are not limited to a rigid and single arrangement form (such as a transverse and longitudinal staggered chessboard arrangement form), thereby meeting the requirements of completely covering the building roof by the drainage channels and quickly constructing.

After the drainage channel switching units 50 of different types are respectively added at the two ends of the assembled sections of the drainage channel units 10, the flexible hinge drainage channel can be connected with any other existing drainage channel through different assembling structures 51. The drain pan adapter unit 50 has a structure substantially similar to that of the drain pan unit 10, except that one end of the drain pan adapter unit 50 is an assembly structure 51. This embodiment is through setting up water drainage tank switching unit 50, and the compatibility of flexible hinge water drainage tank and other water drainage tanks has been guaranteed to the connected mode of greatly richening flexible hinge water drainage tank, further enlarges the application range of flexible hinge water drainage tank. Further, the flexible hinge drain 100 may include only two drain pan adapter units 50, not the drain pan unit 10, subject to the length of the connection location. Of course, the respective assembly structures 51 of the two drain pan adapter units 50 may be different, and both are connected to each other by the connection structure 31 at one end, and both are connected to two different other drain pans by the respective assembly structures 51 at the other end. The flexible hinge gutter 100 at this time is equivalent to a gutter adaptor, and is connected with two other gutters with different assembly structures.

Further, the length of each section of gutter unit 10 will directly affect the minimum arc radius at which the assembled flexible hinge gutter will bend.

When the adjacent drainage channel units 10 are connected, the positions of the drainage channel units 10 are adjusted to align the insertion holes 32 on the two drainage channel units 10, and then the rotating shaft 33 is inserted into the insertion holes 32 to complete the final fixation; after the connection, the two drain tank units 10 can be rotated with respect to each other about the rotation shaft 33. Further, the rotation shaft 33 and the insertion hole 32 as the connection structure 31 may be provided at a single-sided side wall or both-sided side walls of the drain tank unit 10.

The distance between the central axes between the first insertion holes at both ends of the drain tank unit 10 is greater than the distance between the central axes between the second insertion holes at both ends of the drain tank unit 10. When the adjacent drain tank units 10 are connected, the rotating shaft 33 can be selectively inserted into the first insertion hole or the second insertion hole, thereby changing the length of the drain tank unit 10.
