[0017] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0018] like Figure 1-Figure 5 As shown, a trench drainage structure includes a trench 1, a rain flow rack 2 and a cover plate 3. The rain flow rack 2 is arranged on the top of the trench 1, and the cover plate 3 is arranged on the top of the rain flow rack 2. The trench 1 is used for laying cables, process pipelines, etc.; the cover plate 3 can collect rainwater into the rain flow rack 2, and the rainwater flows out through the rain flow rack 2 to prevent the rainwater from affecting the cables or process pipelines in the trench 1.

[0019] Brackets 4 are respectively provided on the inner side of the upper edge of the pipe trench 1, and the rain flow frame 2 is fixedly installed in the bracket 4. The height of the rain flow frame 2 is lower than the height of the upper edge of the pipe trench 1. The bracket 4 makes the rain flow frame 2 stable and firm;

[0020] A rainwater flow channel 5 is provided in the middle of the rainwater flow frame 2, and rainwater can flow in the rainwater flow channel 5 for easy discharge;

[0021] A plurality of fixing grooves 6 are evenly distributed on the inner side wall of the rain flow frame 2; a plurality of water collection channels 7 are arranged in parallel on the lower side of the cover plate 3, and the outer side walls of the water collection channels 7 can cooperate with the fixing grooves 6. When the cover plate 3 is covered on the rain flow frame 2, the cooperation between the water collection channels 7 and the fixing grooves 6 makes the cover plate 3 stable and firm;

[0022] A number of rainwater holes 8 are provided on the upper top surface of the water collecting channel 7, and water outlets 9 are respectively provided at both ends of the water collecting channel 7. The water outlets 9 are located above the rainwater flow channel 5. Rainwater enters the water collecting channel 7 through the rainwater holes 8, and then enters the rainwater flow channel 5 through the water outlets 9.

[0023] Furthermore, ventilation holes 10 are respectively opened on the lower oblique sides of the water collection channel 7. When the weather is clear, wind can freely enter the interior of the trench 1 through the rainwater holes 8 and the ventilation holes 10, thereby enhancing ventilation, facilitating the discharge of hot and humid air inside the trench 1, and improving the internal environment of the trench 1.

[0024] Furthermore, a limit strip 11 is provided on one side of the cover plate 3, and a splicing channel 12 protruding outward is provided on the other side. The limit strip 11 of one cover plate 3 can cooperate with the splicing channel 12 of another cover plate 3. The limit strip 11 cooperates with the splicing channel 12 to make the splicing channel 12 complete, and no leaking gap will appear between the two adjacent cover plates 3, ensuring that rainwater will not enter the interior of the trench 1; and the limit strip 11 has a water-blocking function to prevent rainwater from entering the trench 1 along the lower surface of the cover plate 3.

[0025] Furthermore, a water outlet hole 13 is opened at the bottom of the rain flow rack 2, and a water outlet pipe 14 is connected to the water outlet hole 13. One end of the water outlet pipe 14 passes through the pipe trench 1. The water outlet pipe 14 can be connected to the external drainage channel. Rainwater inside the rain flow rack 2 can enter the external drainage system through the water outlet pipe 14.

[0026] Working principle: The utility model installs a rain flow rack 2 with a rainwater flow channel 5 on the pipe trench 1, and arranges a water collection channel 7 on the cover plate 3, so that rainwater can enter the rainwater flow channel 5 of the rain flow rack 2 through the water collection channel 7 and then be discharged, thereby preventing rainwater from entering the interior of the pipe trench 1; and the cooperation between the two adjacent cover plates 3 through the limiting strip 11 and the splicing channel 12 makes it possible for no leaking gap to appear between the two adjacent cover plates 3, thereby ensuring that rainwater will not enter the interior of the pipe trench 1; the presence of the ventilation holes 10 allows wind to enter the interior of the pipe trench 1 through the rainwater holes 8 and the ventilation holes 10, thereby enhancing ventilation and improving the internal environment of the pipe trench 1.
