[0038] In order to make the above-mentioned purpose, features and advantages of the utility model more apparent, obvious and easy to understand, the specific embodiments of the utility model will be described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0040] As Figures 1-3 The utility model provides a kind of assembled energy dissipation sewage interception device, including box 11, the inside of box 11 is equipped with porous fiber cotton 12, and its top is paved with pebble layer 13. Among them, pebble layer 13 is paved and arranged above porous fiber cotton 12.

[0041] Further, box 11 adopts polygonal column design, preferably adopts cuboid or regular hexagonal column. By adopting polygonal regular polygon column design, it is convenient for subsequent modular assembly combination use.

[0042] Further, box 11 adopts integrated design, and adopts high-strength material, to ensure the structural strength and stability of box. Preferably, high-strength corrosion-resistant plastic material such as ABS is used, which can ensure the structural strength of the assembled energy dissipation sewage interception device, avoid corrosion caused by long-term use, and reduce the use cost on the other hand.

[0043] As Figure 1As shown, the top panel of the box 11 is designed to be open, so as to facilitate the installation of the porous fiber cotton 12 and the paving of the pebble layer 13. Regular drainage openings 1103 are arranged on at least one of the side panels or the bottom panel of the four side panels of the front, back, left and right of the box 11, and a filter grid 14 is arranged at the drainage opening 1103. Among them, the drainage opening 1103 is used for the discharge of the purified rainwater. The sewage formed by the road rainwater flows into the box through the open side stone, and then flows through the pebble layer 13 and the porous fiber cotton 12 in turn. Through the cooperation of the pebble layer 13 and the porous fiber cotton 12, the preliminary filtration and purification of the sewage are realized, so as to efficiently intercept and adsorb the pollutants such as suspended solids, organic matter, nutrient salt and heavy metal in the rainwater.

[0044] Further, the pebble layer 13 is arranged above the porous fiber cotton 12 through the fixed setting of the enclosure. The enclosure is used to fix the shape of the pebble groove, and a plurality of pebbles are paved in the pebble groove to form the pebble layer 13. The arrangement of the enclosure can avoid the scattering of the pebbles by the rainwater.

[0045] Preferably, the drainage openings 1103 are arranged on the side panels and the bottom panel of the four side panels of the front, back, left and right of the box, so as to facilitate the subsequent assembly and use, and ensure the mutual communication between the adjacent boxes after the assembly and combination, which greatly facilitates the outflow of the purified rainwater.

[0046] Further, the filter grid 14 can be a filter screen or be integrally injection molded with the box 11.

[0047] As shown in Figure 1 and Figure 2 In order to avoid that the paved pebble layer 13 is too thick to cause the extrusion deformation of the porous fiber cotton 12 and affect the performance of the porous fiber cotton 12, the box 11 is designed to be layered, including an upper box 1101 and a lower box 1102. Among them, the cavity in the box is divided into two parts through the porous partition plate 15 between the upper and lower boxes, so as to form a space cavity for paving the pebble layer in the upper box 1101 and a space cavity for installing the porous fiber cotton in the lower box 1102.

[0048] Further, a plurality of drainage holes 1501 are regularly arranged on the porous partition plate 15.

[0049] Further, the porous fiber cotton 12 is installed in the lower box 1102, and the drainage openings 1103 are regularly arranged on the side panels and the bottom panel of the lower box 1102.

[0050] Further, a plurality of pebbles are paved in the upper box 1101 to form the pebble layer 13, and the particle size of the pebbles is greater than the size of the drainage holes.

[0051] Preferably, the pebbles adopt 10-30mm particle size pebbles. The small particle size pebbles are not only beautiful, but also the gap between the pebbles is smaller, so that the preliminary filtration of the larger particle size particles in the sewage is facilitated, and the larger particle size particles are prevented from being blocked in the porous baffle or accumulated in the porous fiber cotton, thereby affecting the performance of the porous fiber cotton.

[0052] Further, the overall height / thickness of the pebble layer is lower than the inner cavity height / depth of the upper box body 1101, so that the pebble layer can be arranged in the upper box body 1101. Preferably, in an embodiment, the thickness of the pebble layer is 30-50mm.

[0053] Further, the water permeable geotextile is regularly arranged between the pebble layer 13 and the box body. The water permeable geotextile can not only filter out the larger particle size particles, but also facilitate the cleaning and replacement of the pebbles in the pebble layer. The water permeable geotextile can be used to take out all the pebbles in the box body at one time.

[0054] Further, the porous fiber cotton of the utility model adopts ecological porous fiber cotton. The ecological porous fiber cotton is an environmental protection material, supports the sustainable development of the ecological environment, and the upper pebble layer enhances the natural beauty and harmonizes with the surrounding environment.

[0055] As shown in Figure 3 , the assembled energy dissipation and sewage interception device of the utility model adopts a modular design, and can be assembled and used quickly. Unlike the traditional integrated structure, the device adopts a modular design, and each component can be prefabricated in a factory and connected into an integral device on site through rapid assembly. This design significantly reduces the complexity and time of on-site construction, and improves the installation efficiency and maintainability of the device.

[0056] As shown in Figure 4 and Figure 5 , the assembled energy dissipation and sewage interception device of the utility model is an application schematic diagram.

[0057] As shown in Figure 4 , the open hole side stone 3 is paved between the hard road paving 2 and the green belt 4. After the assembled energy dissipation and sewage interception device 1 of the utility model is assembled, it is arranged and installed close to the rear of the open hole side stone 3, so as to intercept and purify the sewage flowing out of the open hole side stone 3.

[0058] As shown in Figure 5 , the lower part of the hard road paving 2 is the road base 6, and the hard road paving 2 and the open hole side stone 3 are paved on the upper part of the road base 6. When the open hole side stone 3 is paved, the open hole position is flush with the upper surface of the hard road paving 2, or slightly lower than the upper surface of the hard road paving 2, so as to ensure that the rainwater on the hard road paving 2 flows out of the open hole side stone 3.

[0059] Further, as shown in Figure 4and Figure 5 As shown, several assembled energy dissipation and sewage interception devices 1 are assembled and arranged in a green belt 4, and are placed closely behind the perforated curbstones 3. The pebble layer 12 at the upper ends of the assembled energy dissipation and sewage interception devices 1 is lower than the opening position of the perforated curbstones 3. When rainwater flows out of the perforated curbstones 3, it can smoothly flow into the pebble layer at the upper ends of the assembled energy dissipation and sewage interception devices 1.

[0060] Furthermore, a plurality of assembled energy dissipation and sewage interception devices 1 are fixed on a base 8 , and the base 8 provides support and positioning for the plurality of assembled energy dissipation and sewage interception devices.

[0061] Further, such as Figure 4 As shown, several assembled energy dissipation and sewage interception devices 1 are stably installed and arranged in the green belt 4 through several pebbles 5. Through the arrangement of the several pebbles 5, they can cooperate with the pebble layer 12 on the upper end of the several assembled energy dissipation and sewage interception devices 1, integrate with the green belt, and enhance the landscape effect of the device.

[0062] like Figure 5 As shown, below the green belt 4, there is generally a sewer channel, and the drainage outlets 1103 on several assembled energy dissipation and sewage interception devices 1 are connected to the sewer. Therefore, through the cooperation of the pebble layer and the porous fiber cotton, pollutants such as suspended solids, organic matter, nutrients, heavy metals, etc. in the rainwater can be efficiently intercepted and adsorbed, thereby achieving preliminary purification of the rainwater.

[0063] Furthermore, vegetation 7 is planted above the green belt 4 .

[0064] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
