Description

Technical Field

[0001] This utility model relates to the field of bridge deck runoff treatment technology, and in particular to an integrated flip-top cover for the protection of hazardous chemicals. Background Technology

[0002] Bridges serve to connect traffic on both sides of the river, cross obstacles, and improve traffic efficiency. They are major transportation facilities. The surface of a bridge has a good drainage function. The drainage function is mainly carried out by the drainage holes set on both sides of the bridge deck, which can quickly drain the water on the bridge into the water body below, so as to ensure the safety of the main body of the bridge and the safety of vehicles traveling on the bridge.

[0003] During busy traffic, if a liquid hazardous chemical leaks onto the bridge surface, the liquid hazardous chemical will also flow towards the drain hole during its flow. If the liquid hazardous chemical is discharged into the water body below through the drain hole, it will cause serious pollution to the water body and the surrounding environment. Being able to close the drain hole as soon as possible is of paramount importance to control the development of pollution. Therefore, we propose an integrated flip cover for hazardous chemical protection. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model discloses an integrated flip-top cover for the protection of hazardous chemicals. This utility model sets a water grate above the drain hole, sets a flip-top cover above the water grate, and sets a cylinder inside the drain hole to quickly seal the drain hole and reduce the probability of hazardous chemicals flowing into the water body.

[0005] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0006] An integrated flip-top cover for hazardous chemical protection includes a sealing device installed in the drainage holes on both sides of the bridge deck.

[0020] Combined with appendix Figures 1-5An integrated flip-top cover for hazardous chemical protection includes a sealing device installed in the drainage holes 3 on both sides of the bridge deck 1. The sealing device consists of a water grate 4, a cover plate 5, and a cylinder 6. The water grate 4 is located above the drainage holes 3, and a flip-top cover plate 5 is installed above the water grate 4. A cylinder 6 is installed inside the drainage holes 3. The cylinder 6 is hinged to the lower end face of the water grate 4. The upper end of the guide rod of the cylinder 6 is rotatably connected to the cover plate 5. The cylinder 6 is connected to a first air pipe 7 and a second air pipe 8 on the anti-collision walls 2 on both sides of the bridge deck 1. Both the first air pipe 7 and the second air pipe 8 are connected to external solenoid valves. The first air pipe 7 is connected to one end of the air pipe interface of the cylinder 6 through a hose, and the second air pipe 8 is connected to the other end of the air pipe interface of the cylinder 6 through a hose. The cylinder 6 drives the cover plate 5 to flip above the water grate 4 by extending and retracting the guide rod.

[0021] The water grate 4 has hinges 13 distributed on the side near the crash barrier 2. The cover plate 5 is hinged to the water grate 4 through the hinges 13. The lower end of the cover plate 5 is provided with a first lifting lug 11. The guide rod of the cylinder 6 is hinged to the first lifting lug 11. When the guide rod of the cylinder 6 extends, the cover plate 5 opens upward to maintain normal drainage of the bridge deck 1. When the guide rod of the cylinder 6 retracts, the cover plate 5 closes downward to prevent liquid from the bridge deck 1 from being discharged downward through the drain hole 3.

[0022] The cover plate 5 has a chamfered side and a sealing ring 9 is provided on the lower end face of the cover plate 5.

[0023] The sealing ring 9 is made of soft rubber material. The upper end face of the sealing ring 9 is connected to the lower end face of the cover plate 5, and the lower end face of the sealing ring 9 abuts against the upper end face of the grate 4. After the cover plate 5 is lowered, pressure is applied to the sealing ring 9. After the outer edge of the sealing ring 9 is subjected to force, it extends upward and outward along the chamfered slope of the cover plate 5, pushing the sand and other particles left on the grate 4 outward, reducing the gap between the cover plate 5 and the grate 4, and improving the sealing performance.

[0024] The water grate 4 is provided with a sliding groove 10. The first lifting lug 11 passes through the sliding groove 10 at its lower end. Two second lifting lugs 12 are symmetrically provided on both sides of the sliding groove 10. A middle swing connecting assembly is provided between the two second lifting lugs 12. The cylinder 6 is set on the middle swing connecting assembly. The cylinder 6 swings between the two second lifting lugs 12 through the middle swing connecting assembly.

[0025] The mid-swing connection assembly includes a connecting ring 14 and a rotating shaft 15. Two rotating shafts 15 are symmetrically arranged on both sides of the connecting ring 14. The rotating shafts 15 are rotatably connected to the adjacent second lifting lug 12. A cylinder 6 is installed on the connecting ring 14. The connecting ring 14 is sleeved on the cylinder 6, and the guide rod of the cylinder 6 passes through the connecting ring 14.

[0026] The embodiment describes an integrated flip-top cover for hazardous chemical protection. In use, the first air pipe 7 is connected to one end of the air pipe interface of the cylinder 6 via a flexible hose, and the second air pipe 8 is connected to the other end of the air pipe interface of the cylinder 6 via a flexible hose. The cylinder 6 is then installed on the connecting ring 14, and the water grate is installed above the drain hole 3. The guide rod of the cylinder 6 is connected to the first lifting lug 11. During normal drainage, the guide rods of each cylinder 6 are extended to open the cover 5 upwards, maintaining normal drainage of the bridge deck 1. If hazardous chemicals leak from the bridge deck 1, the guide rods of each cylinder 6 are retracted to close the cover 5 downwards, preventing liquid from the bridge deck 1 from flowing downwards through the drain hole 3. When the cover 5 is closed, pressure is applied to the sealing ring 9. Under pressure, the outer edge of the sealing ring 9 extends upwards and outwards along the chamfered slope of the cover 5, pushing outwards any sand or other particles left on the water grate 4, reducing the gap between the cover 5 and the water grate 4, and improving sealing.
