DETAILED DESCRIPTION
[0017] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] like Figures 1 to 3 As shown, this embodiment discloses a rainwater drainage facility for an airfield outlet, including an outlet box culvert 1 and a drainage ditch box culvert 2, the outlet box culvert 1 is provided with a connecting port 11 for communicating with the drainage ditch box culvert 2; a fence device 3 is provided inside the outlet box culvert 1, the fence device 3 includes a lifting screw 31 and a grille 32, and the fence device 3 is connected to an electric control device 33; the outlet box culvert 1 has a top plate 12 flush with the ground, the top plate 12 is provided with a reserved hole 13, the lifting screw 31 extends to the outside of the outlet box culvert 1 through the reserved hole 13 to form a screw extension section 311.
[0019] Among them, according to the instructions of the electronic control device 33, the grille 32 can be raised and lowered along the lifting screw 31 and fixed to at least the closing position, the drainage position and the maintenance position; wherein the grille 32 at the closing position completely blocks the connecting port 11, the grille 32 at the drainage position at most partially blocks the connecting port 11, and the grille 32 at the maintenance position is located at the screw extension section 311.
[0020] When the grille 32 is in the closed position, it can prevent animals and people from invading the flight area. At the same time, there are pores on the grille 32, and water can flow out through the pores of the grille 32. The electric control device 33 can be controlled manually or electrically. According to the drainage needs, the grille 32 in the closed position is raised to a drainage position by controlling the electric control device 33. At this time, the grille 32 partially blocks or does not block the connecting port 11 at all. When the grille 32 is in the drainage position with maximum drainage capacity, the bottom of the grille 32 is higher than the top of the connecting port 11 to increase the water flow capacity. At this time, the grille 32 is still located below the ground as a whole. By controlling the electric control device 33, the grille 32 in the drainage position is further raised to the maintenance position through the reserved hole 13. When the grille 32 is in the maintenance position, the grille 32 is completely exposed above the ground to facilitate the maintenance and replacement of the grille.
[0021] Specifically, the top of the drainage ditch culvert 2 is not lower than the upper edge of the connecting port 11, thereby ensuring that the connecting port 11 is located within the opening range of the drainage ditch culvert 2, and ensuring that the entire cross-section of the connecting port 11 can be connected to the drainage ditch culvert 2 to ensure the drainage capacity of the system. The top plate 12 of the drainage ditch culvert 2 can be backfilled with soil until it is flush with the ground.
[0022] Specifically, the inner side and the outer side of the outlet culvert 1 are respectively provided with a communication port 11, and each communication port 11 is respectively provided with a fence device 3. The inner side of the outlet culvert 1 faces the inside of the flight zone, and the outer side of the outlet culvert 1 faces the outside of the flight zone. The technical solution can prevent animals and people from entering the outlet culvert 1 from both sides of the outlet culvert 1.
[0023] More specifically, a U-shaped open ditch 4 is provided between the inner side of the drainage ditch culvert 2 and the outlet culvert 1, and patrol roads, maintenance stairs, corrugated anti-collision guardrails and other facilities can be set in the U-shaped open ditch 4 to facilitate weeding, dredging and maintenance of facilities in the drainage system.
[0024] More specifically, a middle wall 14 is provided in the outlet box culvert 1 along the drainage direction, and the outlet box culvert 1 is divided into a plurality of channels by the middle wall 14. A plurality of communication ports 11 are provided on the inner side and the outer side of the outlet box culvert 1, respectively, and each communication port 11 is correspondingly provided on the inner side or the outer side of the channel. Since an independently controlled fence device 3 can be provided in each channel, the opening and closing of the fence device 3 at the corresponding communication ports 11 of different channels can be adjusted separately according to the rainfall and drainage needs.
[0025] Specifically, the electric control device 33 includes an electric gate hoist, which is arranged on the screw extension section 311. With this technical solution, maintenance personnel only need to operate the electric gate hoist on the ground to control the position of the fence device without going to the bottom of the box culvert for manual control, thereby reducing safety risks.
