Description

Technical Field

[0001] This application relates to the technical field of building drainage, and particularly to a greening drainage device. Background Art

[0002] With the acceleration of the urbanization process, building greening, as an effective means to increase the urban greening area, has received increasing attention. Building greening can not only improve the urban environment, but also alleviate the urban heat island effect to a certain extent and enhance the living quality of residents. Therefore, building greening technology has been widely applied and developed.

[0003] Traditional building greening usually adopts a drainage design method of opening a drainage outlet on one side of the greening pool, allowing the water accumulated in the greening pool to drain through the drainage outlet. However, this method often has a slow drainage speed during the rainy season, and the accumulated water stays at the root for a long time, which is likely to cause the roots of the green plants to rot. Utility Model Content

[0004] In order to improve the drainage efficiency of building green spaces, this application provides a greening drainage device.

[0005] This application provides a greening drainage device, adopting the following technical solutions:

[0006] A greening drainage device includes a drainage board group and a filter cloth. The drainage board group includes a plurality of spliced drainage boards. A number of drainage channels are distributed in the drainage board, and the drainage channels horizontally penetrate both sides of the drainage board; on the upper surface of the drainage board, a number of drainage holes communicating with the drainage channels are spaced along the direction of the drainage channels; the filter cloth is laid on the surface of the drainage board.

[0007] By adopting the above technical solutions, setting the drainage board below the soil can effectively drain water and reduce the residence time of accumulated water in the soil; at the same time, the filter cloth can isolate the soil from the water, making it easy for the accumulated water to carry soil when draining into the drainage channels and preventing the soil from being easily lost.

[0008] Optionally, the cross-section of the drainage channel is in a water droplet shape with a smaller upper part and a larger lower part.

[0009] By adopting the above technical solutions, the drainage efficiency of the drainage channel is further improved because the water droplet shape helps to accelerate the water flow speed and reduce the residence time of water in the drainage board.

[0010] Optionally, one side of the drainage board is provided with a convex strip, and a groove for the convex strip to be inserted and adapted is opened on the opposite side.

[0011] By adopting the above technical solutions, the splicing of the drainage boards is more firm, effectively preventing the loosening of the splicing joints and ensuring the stability of the entire drainage system.

[0012] Optionally, the drainage board group further includes a splicing component for fixedly connecting adjacent drainage boards.

[0013] By adopting the above technical solution, the overall connection stability of the drainage board group is improved, facilitating installation and maintenance.

[0014] Optionally, the splicing component includes a pull rope, a fastener, and two tensioning slats. A rope passing hole is horizontally formed through the middle of one side in the length direction of the drainage board. The two tensioning slats are installed at both ends in the length direction of the drainage board group. Through holes communicating with the drainage channels are formed in the tensioning slats. After the pull rope passes through the two tensioning slats and the rope passing hole of the drainage board group and is tightened, it is fixed by the fastener.

[0015] By adopting the above technical solution, the tight connection between the drainage boards is ensured, and the stability and durability of the entire device are improved.

[0016] Optionally, a sleeve inserted into the rope passing hole is fixed to one side of the tensioning slat facing the drainage board, and the pull rope passes through the sleeve and extends outside the tensioning slat.

[0017] By adopting the above technical solution, when the sleeve is inserted into the rope passing hole, the connection stability between the tensioning slat and the drainage board can be improved.

[0018] Optionally, the fastener includes a main body pipe head and a pressing nut threadedly connected to the main body pipe head. One end of the main body pipe head is provided with a plurality of clamping claws extending along the axis of the main body pipe head. The plurality of clamping claws are circumferentially and equally spaced around the axis of the main body pipe head. One end of the pressing nut is provided with a pressing portion with a diameter gradually decreasing from inside to outside. The clamping claws are bent inward under the action of the pressing portion of the pressing nut. A limiting ring for abutting against the surface of the tensioning slat is fixed to the outer peripheral side of the main body pipe head.

[0019] By adopting the above technical solution, the firm fixation of the pull rope is achieved, the loosening of the pull rope is prevented, and the overall stability of the splicing component is improved.

[0020] Optionally, the pressing member includes a threaded post and a locking nut. The threaded post is fixed to the side of the tensioning slat facing away from the sleeve. The threaded post is coaxially communicated with the sleeve. A notch for the pull rope to pass through is formed in the outer peripheral side of the threaded post along the axis direction. The locking nut is used to press the pull rope extending out of the notch against the tensioning slat.

[0021] By adopting the above technical solution, the pull rope can extend out of the notch, be wound around the threaded post, and then be locked by the locking nut, improving the stability when the pull rope is fixed.

[0022] In summary, the present application includes at least one of the following beneficial effects:

[0023] 1. The basic structure of the greening drainage device is realized, the drainage efficiency is improved, and at the same time, the soil is protected from erosion by the filter cloth. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present application will be further described in detail below with reference to the accompanying drawings.

[0038] Embodiment 1

[0039] Refer to Figure 1 、 2, an embodiment of the present application discloses a greening drainage device, which includes a drainage board group 1 and a filter cloth 2. The drainage board group 1 includes a plurality of spliced drainage boards 11. The splicing of the drainage boards 11 is in two directions. One is arranged horizontally along the width direction of the greening pool, and the other is arranged longitudinally along the length direction of the greening pool. A number of drainage channels 111 are equally spaced within the drainage board 11. The plurality of drainage channels 111 are parallel to each other and penetrate both sides of the drainage board 11 in the horizontal direction.

[0040] Refer to Figure 3 , on the upper surface of the drainage board 11 along the direction of the drainage channels 111, a number of drainage holes 112 communicating with the drainage channels 111 are equally spaced. The water in the soil can flow into the drainage channels 111 through the drainage holes 112 and be discharged into the drain pipe or drainage ditch by the drainage channels 111. The residence time of accumulated water in the soil is effectively reduced.

[0041] Refer to Figure 2 , the filter cloth 2 is laid on the upper surface of the drainage board group 1 to prevent the soil from flowing into the drainage channels 111 along with the water flow and reduce the occurrence of soil loss. The filter cloth 2 can adopt existing geotextiles, and this embodiment does not limit the filter cloth 2.

[0042] Refer to Figure 3 , the cross-section of the drainage channel 111 is in a water droplet shape with a smaller upper part and a larger lower part. This structure can guide the water to the drainage outlet faster, thus accelerating the drainage process. To solve the drainage problem in practical applications, drainage channels 111 with other shaped structures can be selected, such as trumpet-shaped, strip-shaped with a smaller upper part and a larger lower part, or channels with similar shapes.

[0043] Refer to Figure 3 , a convex strip 114 is provided on one side of the drainage board 11, and a groove 113 for the convex strip 114 to be inserted and adapted is provided on the opposite side. The convex strip 114 and the plate body are made by an integral molding method, ensuring the structural strength of the drainage board 11 during splicing. Both the convex strip 114 and the groove 113 extend along the length direction of the drainage channels 111 of the drainage board 11. When arranged horizontally, adjacent drainage boards 11 form a relatively stable joint through the cooperation of the convex strip 114 and the groove 113.

[0044] Refer to Figure 2 、 4 , the drainage board group 1 further includes a splicing component 12 for fixedly connecting adjacent drainage boards 11. The splicing component 12 includes a pulling rope 121, a fastening member 123, and two tensioning plates 122.

[0045] Specifically. Refer to Figure 4 、 5, a rope passing hole 115 is horizontally penetrated through the middle of one side of the drainage board 11 in the length direction, and two tensioning slats 122 are installed at both ends of the drainage board group 1 in the drainage direction. A through hole 1221 for the tensioning rope 121 to pass through and a water passing hole 1223 communicating with the drainage channel 111 are provided on the tensioning slat 122. After the tensioning rope 121 passes through the through holes 1221 of the two tensioning slats 122 and the rope passing hole 115 of the drainage board group 1 and is tightened, it is fixed by a fastener 123.

[0046] A sleeve 1222 inserted into the rope passing hole 115 is fixed to one side of the tensioning slat 122. Inserting the sleeve 1222 into the rope passing hole 115 can improve the stability of the tensioning slat 122.

[0047] Refer to Figure 5 、 6 , the fastener 123 includes a main body pipe head 1231 and a tightening nut 1232. An axially extending thread is provided on the outer peripheral side of the main body pipe head 1231, and the tightening nut 1232 is threadedly connected to the main body pipe head 1231. One end of the main body pipe head 1231 is provided with a plurality of clamping claws 1233 extending along the axis direction of the main body pipe head 1231, and the plurality of clamping claws 1233 are circumferentially and equally spaced around the axis of the main body pipe head 1231; one end of the tightening nut 1232 is provided with a tightening portion 1234 with a diameter gradually decreasing from inside to outside.

[0048] After the tightening nut 1232 is screwed onto the main body pipe head 1231, the clamping claws 1233 are bent inward under the action of the tightening portion 1234 of the tightening nut 1232, thereby pressing the tensioning rope 121 inserted into the main body pipe head 1231.

[0049] A limiting ring 1235 for abutting against the surface of the tensioning slat 122 is fixed to the outer peripheral side of the main body pipe head 1231. After the main body pipe head 1231 is inserted into the through hole 1221, the limiting ring 1235 can abut against the surface of the tensioning slat 122 for limiting.

[0050] After the drainage board group 1 is spliced, the tensioning rope 121 at one end is locked and fixed by the tightening nut 1232, then the tensioning rope 121 is pulled taut, and then the other end of the tensioning rope 121 is locked by the tightening nut 1232, and the installation of the drainage board group 1 can be completed.

[0051] Embodiment 2

[0052] The difference between this embodiment and the above-mentioned Embodiment 1 lies in the fastener 123. Refer to Figure 7 、 8The fastener 123 includes a threaded column 1236 and a locking nut 1237. The locking nut 1237 can be threadedly connected to the threaded column 1236. The threaded column 1236 is fixed to the side of the tensioning strip 122 away from the sleeve 1222. The threaded column 1236 is coaxially arranged with the sleeve 1222. A notch 1238 is provided on the outer peripheral side of the threaded column 1236 along the axial direction for the pull rope 121 to pass through.

[0053] When the pull rope 121 is tightened, the pull rope 121 extends out from the notch 1238 and wraps around the outer circumference of the threaded column 1236 for several circles. The locking nut 1237 is screwed onto the threaded column 1236. The pull rope 121 is pressed against the tensioning slat 122 by the locking nut 1237, thereby fixing the pull rope 121.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
