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 mortise and tenon drainage groove which is used for solving the problem that the drainage groove is single in arrangement shape and connection form, achieving the effects that the drainage grooves are arranged in various shapes and positions and are connected at various different angles, and further meeting the requirements of completely covering a building roof and quickly constructing the drainage groove.

The utility model adopts the technical scheme that the flexible mortise and tenon drainage groove comprises a plurality of drainage groove units and drainage groove switching units; two ends of each section of drainage groove unit are provided with connecting structures; the drainage tank units are connected with each other through a connecting structure; one end of the drainage channel switching unit is provided with a connecting structure, and the other end of the drainage channel switching unit is provided with an assembling structure used for being connected with other types of drainage channels; and after the plurality of sections of drainage groove units are sequentially connected one by one, the two ends of the drainage groove units are respectively connected with the drainage groove switching units to form the flexible mortise and tenon drainage groove.

The two ends of each drainage channel unit are provided with connecting structures, after every two drainage channel units are connected in sequence, the two ends of each drainage channel unit are respectively connected with the drainage channel switching units to be assembled into the flexible mortise and tenon drainage channel. The two ends of the flexible mortise and tenon drainage groove can be connected with the existing drainage groove through the assembling structure. On one hand, as any two drainage channel units can be connected with each other through the connecting structure by a plurality of rotation angles with different specifications, the whole drainage channel composed of a plurality of sections of drainage channel units has certain flexibility relative to the existing straight-through drainage channel, and can be adjusted to be in a proper shape according to the specific shape or position of a building roof. Specifically, the flexible mortise and tenon drainage groove can be integrally adjusted to be C-shaped, S-shaped and the like. Of course, in order to avoid the building structure on the building roof, the flexible mortise and tenon drainage groove can be adjusted to other irregular shapes. In addition, compare in the limited length specification of current straight-through water drainage tank, the length specification of flexible mortise and tenon water drainage tank is nimble changeable. Along with the gradual increase or reduction of the quantity of the drainage channel units that connect gradually one by one in proper order, the whole length of flexible mortise and tenon drainage channel also gradually increases or reduces. The length of the flexible mortise and tenon drainage groove is freely increased or decreased by taking a drainage groove unit as a unit until the requirement of connection between the drainage grooves is met. Therefore, the flexible mortise and tenon 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 multiple shapes, multiple positions and multiple lengths 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.

In a preferred arrangement, the straight-through drainage channels are connected at the angles of three corners of a triangle. 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 mortise and tenon drainage groove can be used for adjusting the rotation angle between each drainage groove unit, so that two ends of the flexible mortise and tenon drainage groove can obtain a plurality of different connection angles, and the flexible mortise and tenon drainage groove is equivalent to a drainage groove connector which is used for connecting two straight-through drainage grooves which are arranged at non-right angles. Therefore, the flexible mortise and tenon drainage grooves solve the problem of single connection form of the drainage grooves and achieve the effect of connection between the drainage grooves at a plurality of different angles.

According to the scheme, the flexible connection between the drainage grooves and the flexible connection between the drainage grooves are realized through the plurality of sections of drainage groove units, so that the drainage grooves can adopt an irregular and better arrangement scheme according to the specific shape and the construction requirements of the building roof, and are not limited to a rigid and single arrangement form (such as a transverse and longitudinal staggered chessboard layout form), and the requirements of the drainage grooves on completely covering the building roof and quick construction are met.

The existing drainage channels are various in types, the assembly structures of the drainage channels of different brands are different from each other, and even the assembly structures of the drainage channels of different series of the same brand are different from each other. After the drainage channel switching units of different types are respectively added at the two ends of the assembled drainage channel units, the flexible mortise and tenon drainage channels can be connected with the existing any other drainage channels through different assembling structures. The drain tank switching unit has a structure substantially similar to that of the drain tank unit, except that one end of the drain tank switching unit is an assembly structure. This scheme is through setting up water drainage tank switching unit, and the flexible mortise and tenon water drainage tank's of very big abundance connected mode has guaranteed the compatibility of flexible mortise and tenon water drainage tank and other water drainage tanks, further enlarges the application range of flexible mortise and tenon water drainage tank. In addition, when being restricted by the length of the connecting position, the flexible mortise and tenon drainage groove can only comprise two drainage groove switching units and does not comprise a drainage groove unit. Of course, the respective assembly structures of the two drainage channel switching units can also be different, the two can be connected with each other through the connection structure at one end, and the two can be connected with other drainage channels with two different types through the assembly structures at the other ends. The flexible mortise and tenon water drainage groove at the moment is equivalent to a water drainage groove adaptor and is connected with two other water drainage grooves with different assembly structures.

Further, the length of each drainage groove unit directly influences the minimum circular arc radius of the bending of the assembled flexible mortise and tenon drainage groove. In this scheme, the central distance of the connection structure who uses water drainage tank unit both ends is the festival length of water drainage tank unit to the distance between two water inlets that the side of leading-through water drainage tank set up is the length of cutting apart of flexible water drainage tank. The length of the joint can be designed into various length specifications according to the requirement of mass production, and the length of the joint ranges from 1 to 3 division lengths.

Preferably, the connection structure of water drainage tank unit includes fourth of the twelve earthly branches structure and tenon structure, and fourth of the twelve earthly branches structure sets up the upper portion surface at the one end of water drainage tank unit, and the tenon structure sets up the upper portion surface at the other end of water drainage tank unit.

Furthermore, the mortise structure is a groove which is linearly arranged and has depth and angle; the tenon structure is a protrusion with height and angle which are arranged linearly.

This scheme adopts mortise and tenon structure as the connection structure of water drainage tank unit, including mortise and tenon structure. Mortise and tenon structure sets up respectively on the upper portion surface of water drainage tank unit, does not influence the inside space of water drainage tank unit, avoids causing the disturbance to the infiltration water that flows in its inside. The groove in the mortise structure is equivalent to a mortise, and the bulge in the tenon structure is equivalent to a tenon. During installation, the tenon structure at one end of one drainage channel unit is matched with the mortise structure at one end of the other drainage channel unit to complete connection between the adjacent drainage channel units. Taking the length direction of the drainage channel unit as a reference, and taking the included angle between the groove and the length direction as the angle of the mortise structure; the included angle between the protrusion and the length direction is the angle of the tenon structure; the included angle of mortise and tenon structure after cooperation is the offset angle, also is the angle of mortise and tenon structure. When the mortise and tenon structure has an offset angle, after the tenon structure is matched with the mortise structure, the adjacent drainage groove units can be connected with each other by a fixed rotation angle. The mortise and tenon structures on the drainage channel units with different specifications have different offset angles, and the two drainage channel units can be connected with each other by a plurality of different rotation angles. Furthermore, the mortise structure comprises a plurality of grooves which are linearly arranged and have certain depth and offset angle, and the tenon structure comprises a plurality of protrusions which are linearly arranged and have certain height and offset angle. Because the groove or the bulge is provided with a plurality of strips, the mortise structure and the tenon structure of the two drainage groove units can be partially matched. When the mortise and tenon structure part is matched, the rotating angle between the two drainage groove units is unchanged, but the distance between the two drainage groove units can be changed, and the effect of flexibly adjusting the arc radius of the bent flexible mortise and tenon drainage groove after assembly is achieved. The distance between the drainage groove units is far, the radius of the arc of the flexible mortise and tenon drainage groove is large, and vice versa. Therefore, when the flexible mortise and tenon drainage groove is used, the arc radius of the flexible mortise and tenon drainage groove can be adjusted by the rotation angle and the interval between the drainage groove units so as to meet the connection requirements of actual sites for different radians.

Furthermore, the angle of the mortise structure or the tenon structure is 35-55 degrees.

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 mortise and tenon drainage channel, which includes a plurality of drainage channel units 10 and a drainage channel switching 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; 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 sequentially connected one by one, the two ends of the drainage channel units are respectively connected with the drainage channel switching units 50 to form the flexible mortise and tenon drainage channel.

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 units 50 to assemble the flexible mortise and tenon drainage channel 100. Both ends of the flexible mortise and tenon drainage groove can be connected with the existing drainage groove through the assembly structure 51. On one hand, since any two drainage channel units 10 can be connected with each other through the connecting structure 31 at a plurality of rotation angles with different specifications, the whole drainage channel composed of a plurality of sections of drainage channel units 10 has certain flexibility relative to the existing straight-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 mortise and tenon drainage groove can be integrally adjusted to be C-shaped, S-shaped and the like. Of course, in order to avoid the building structure on the building roof, the flexible mortise and tenon drainage groove can be adjusted to other irregular shapes. In addition, compared with the limited length specification of the existing straight-through drainage channel 210, the length specification of the flexible mortise and tenon drainage channel is flexible and changeable. Along with the gradual increase or reduction of the quantity of the drainage channel units 10 that connect gradually one by one in proper order, the whole length of flexible mortise and tenon drainage channel also gradually increases or reduces. The length of the flexible mortise and tenon drainage groove is freely increased or decreased by taking a drainage groove unit 10 as a unit until the requirement of connection between the drainage grooves is met. Therefore, the flexible mortise and tenon 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 multiple shapes, multiple positions and multiple lengths 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 scheme of the straight-through drainage channel 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 are connected at the angles of three corners of a triangle. 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 mortise and tenon drainage groove can be used for enabling two ends of the flexible mortise and tenon drainage groove to obtain a plurality of different connection angles by adjusting the rotation angle between each drainage groove unit 10, and is equivalent to a drainage groove connector for connecting two straight drainage grooves which are arranged at non-right angles. Therefore, the flexible mortise and tenon drainage grooves solve the problem of single connection form of the drainage grooves and achieve the effect of connection between the drainage grooves at a plurality of different angles.

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.

The existing drain grooves are various in types, and the assembling structures 51 of the drain grooves of different brands are different from each other, and even the assembling structures 51 of the drain grooves of different series of the same brand are different from each other. After the drainage groove switching units 50 of different types are respectively added at two ends of the assembled drainage groove units 10, the flexible mortise and tenon drainage groove can be connected with any other existing drainage groove through different assembly 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 flexible mortise and tenon water drainage tank's of very big abundance connected mode has guaranteed the compatibility of flexible mortise and tenon water drainage tank and other water drainage tanks, further enlarges the application range of flexible mortise and tenon water drainage tank. In addition, the flexible mortise and tenon joint drain 100 may include only two drain fitting unit 50 without the drain fitting unit 10, subject to the length of the connection position. Of course, the respective assembly structures 51 of the two drain pan adapter units 50 may also be different, and both may be connected to each other by the connection structure 31 at one end, and both may be connected to two different other drain pans by the respective assembly structures 51 at the other end. The flexible mortise and tenon drainage groove 100 at this time is equivalent to a drainage groove adaptor and is connected with two other drainage grooves with different assembly structures.

Further, the length of each drainage channel unit 10 will directly affect the minimum arc radius of the bending of the assembled flexible mortise and tenon drainage channel. In this embodiment, the center distance of the connecting structures 31 at the two ends of the drainage channel unit 10 is used as the pitch length of the drainage channel unit 10, and the distance between the two water inlets arranged on the side surface of the straight-through drainage channel 210 is used as the division length of the flexible drainage channel. The length of the joint can be designed into various length specifications according to the requirement of mass production, and the length of the joint ranges from 1 to 3 division lengths.

As shown in fig. 3 and 4, preferably, the connection structure 31 of the drainage channel unit 10 includes a mortise structure 32 and a tenon structure 34, the mortise structure 32 is disposed on the upper surface of one end of the drainage channel unit 10, and the tenon structure 34 is disposed on the upper surface of the other end of the drainage channel unit 10.

Further, the mortise structure 32 is a groove 33 which is linearly arranged and has depth and angle; the tenon structure 34 is a linear array of height and angle protrusions 35.

The mortise and tenon structure is adopted as the connecting structure 31 of the drainage groove unit 10 in the embodiment, and comprises a mortise and tenon structure 32 and a tenon structure 34. Mortise structure 32 and tenon structure 34 set up respectively on the upper portion surface of water drainage tank unit 10, do not influence the inside space of water drainage tank unit 10, avoid causing the disturbance to the infiltration water that flows in its inside. The recesses 33 in the mortise structure 32 correspond to mortises and the protrusions 35 in the tenon structure 34 correspond to tenons. During installation, the tenon structure 34 at one end of one drainage groove unit 10 is matched with the mortise structure 32 at one end of the other drainage groove unit 10 to complete connection between the adjacent drainage groove units 10. Taking the length direction of the drainage channel unit 10 as a reference, and taking the included angle between the groove 33 and the length direction as the angle of the mortise structure 32; the included angle between the protrusion 35 and the length direction is the angle of the tenon structure 34; the included angle between the mortise and tenon structure 32 and the tenon structure 34 is an offset angle, i.e. the angle of the mortise and tenon structure. When the mortise and tenon structure has an offset angle, after the tenon structure 34 and the mortise structure 32 are matched, the adjacent drainage channel units 10 can be connected with each other at a fixed rotation angle. The mortise and tenon structures on the drainage channel units 10 with different specifications have different offset angles, and the two drainage channel units 10 can be connected with each other by a plurality of different rotation angles. Further, the mortise structure 32 includes a plurality of linearly arranged grooves 33 having a certain depth and an offset angle, and the tenon structure 34 includes a plurality of linearly arranged protrusions 35 having a certain height and an offset angle. The mortise and tenon structures 32 and 34 of the two drainage groove units 10 can be partially matched due to the plurality of grooves 33 or protrusions 35. When the mortise and tenon structure parts are matched, the rotation angle between the two drainage groove units 10 is unchanged, but the distance between the drainage groove units is changed, so that the effect of flexibly adjusting the curved arc radius of the assembled flexible mortise and tenon drainage groove 100 is achieved. The distance between the drainage groove units 10 is far, the radius of the arc of the flexible mortise and tenon drainage groove 100 is larger, and vice versa. Therefore, when the flexible mortise and tenon drainage groove 100 is used, the arc radius of the flexible mortise and tenon drainage groove 100 can be adjusted by the rotation angle and the interval between the drainage groove units 10, so that the connection requirements of actual sites on different radians are met. In this embodiment, the cross sections of the mortise structure 32 and the tenon structure 34 are trapezoidal.

Furthermore, the angle of the mortise structure 32 or the tenon structure 34 is 35 ° to 55 °.

Further, the upper surface of the connecting portion 30 is flush with the upper surface of the main body 20.

The cross-sectional shape of the body 20 is substantially the same as that of the conventional drain tank, and is designed specifically according to different requirements. The connecting portion 30 has a sheet-like structure in which an upper edge of one end of the main body 20 extends outward. The connecting portion 30 corresponds to an overhanging structure of the main body 20. The connection part 30 has only an upper surface without sidewalls to prevent the sidewalls from interfering when the adjacent two drain tank units 10 are connected at a rotation angle. In addition, after two adjacent water drainage tank units 10 are connected, a certain gap exists between the side walls of the main body 20, and the water drainage tank can be used as a water inlet of a flexible water drainage tank consisting of a plurality of sections of water drainage tank units 10, so that the seepage water can be absorbed from the soil, and the siphon drainage function is completed. In this embodiment, the mortise structure 32 is disposed on the lower surface of the connecting portion 30, and the tenon structure 34 is disposed on the upper surface of the end of the main body 20 away from the connecting portion 30.
