[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In this embodiment, a side of a guardrail inspection opening device close to the protected intelligent traffic monitoring facility is its inner side.

[0023] The utility model provides a guardrail maintenance opening device, comprising a three-wave guardrail body 1, a connecting structure 1, a connecting structure 2, and a three-wave opening door panel 2. The three-wave guardrail body 1 is provided with an opening, one end of the three-wave opening door panel 2 is connected to one side of the opening via the connecting structure 1, and the other end of the three-wave opening door panel 2 is connected to the other side of the opening via the connecting structure 2. Through the arrangement of the three-wave opening door panel 2, when the three-wave opening door panel 2 is in an open state, a worker can quickly move from one side of the three-wave guardrail body 1 to the other side through the opening, making it convenient for the worker to inspect and maintain the smart traffic monitoring facility protected by the guardrail. When the three-wave opening door panel 2 is in a closed state, the three-wave guardrail body 1 and the three-wave opening door panel 2 form an integral structure, which is convenient for protecting the smart traffic monitoring facility.

[0024] The above-mentioned connection structure includes a connecting plate 3 fixedly connected to the inner side of one end of the three-wave opening door panel 2 and a limiting plate 4 fixedly connected to the inner side of one end of the opening. The end of the limiting plate 4 close to the connecting plate 3 is located on the inner side of the three-wave opening door panel 2. When the three-wave opening door panel 2 is in a closed state, the gap between one end of the three-wave opening door panel 2 and the three-wave guardrail body 1 is blocked by the limiting plate 4 to ensure the strength of the device.

[0025] A through-hole is provided in the middle of the stopper plate 4 near one end of the connecting plate 3. A through-hole is also provided in the middle of the connecting plate 3 near one end of the stopper plate 4. Both the through-hole and the through-hole are penetrated by screw rod 5, and the through-holes and the through-holes are arranged alternately. The through-holes contact the through-holes, and screw rod 5 is movably connected to both the through-holes and the through-holes, allowing the connecting plate 3 to rotate in the direction of screw rod 5. A nut is fixedly connected to the top of screw rod 5, and a nut 11 is threadedly connected to the outer ring of screw rod 5. Nut 11 is used to secure screw rod 5 to the stopper plate 4.

[0026] From the above description, it can be seen that one end of the three-wave opening door panel 2 is movably connected to the three-wave guardrail body 1 through the connecting structure 1, and the three-wave opening door panel 2 can rotate along the direction of the screw 1 5.

[0027] The second connection structure includes a limiting plate 28 fixedly connected to the other inner side of the three-wave opening door panel 2 and a connecting plate 26 fixedly connected to the inner side of the other end of the opening. The limiting plate 28 extends to the outside of the three-wave opening door panel 2 near one end of the connecting plate 26. When the three-wave opening door panel 2 is in a closed state, the gap between the other end of the three-wave opening door panel 2 and the three-wave guardrail body 1 is blocked by the limiting plate 28 to ensure the strength of the device.

[0028] Another through hole is provided in the middle of the limiting plate 28 near one end of the connecting plate 26, and another through hole is provided in the middle of the connecting plate 26 near one end of the limiting plate 28. When the three-wave opening door panel 2 is in a closed state, the other through hole is in contact with the other through hole, and the other through hole is alternately arranged with the other through hole. The other through hole and the other through hole are penetrated by the screw 27 at the same time, and the other through hole and the other through hole are in a state of active connection with the screw 27, which facilitates the movement of the screw 27. When the screw 27 is taken out, the limiting plate 28 and the connecting plate 26 can be separated, so that the three-wave opening door panel 2 can be opened.

[0029] The screw rod 1 5 and the screw rod 2 7 have the same size. A nut is fixed on the top of both the screw rod 1 5 and the screw rod 2 7. The outer diameter of the nut is larger than the inner diameter of the through hole. The bottom end of both the screw rod 1 5 and the screw rod 2 7 is threadedly connected with a nut 11. The outer diameter of the nut 11 is larger than the inner diameter of the through hole. The nut 11 can be used to fix the screw rod 2 7 and the connecting plate 2 6 together, so that the three-wave opening door panel 2 can be closed.

[0030] The nut 11 includes a nut body 12, and the top of the nut body 12, the outer surface of the through hole and the outer surface of the through hole are all fixed with sealing strips 10. Through the setting of the sealing strip 10, the sealing between the through hole and the through hole can be improved, and the sealing between the nut 11 and the limiting plate 1 4 or the connecting plate 2 6 can be improved, thereby reducing the probability of water vapor contacting with the screw 1 5 or the screw 2 7, extending the service life of the screw 1 5 and the screw 2 7, and facilitating the disassembly and assembly of the screw 1 5 and the screw 2 7. The sealing gasket material can be rubber, and the bottom of the nut body 12 is fixedly connected with a sealing sleeve 9. Through the setting of the sealing sleeve 9, the exposed part of the screw 1 5 or the screw 2 7 can be wrapped to prevent the bottom end of the screw 1 5 or the bottom end of the screw 2 7 from rusting, thereby facilitating the disassembly and assembly of the nut 11.

[0031] Reflective strips 13 are provided on the outside of the three-wave opening door panel 2 and the three-wave guardrail body 1. The heights of the three-wave opening door panel 2 and the three-wave guardrail body 1 are consistent. Square columns are provided on the inside of the three-wave guardrail body 1, and the limiting plate 1 4 and the connecting plate 2 6 are both overlapped and installed with the square columns, which effectively improves its overall consistency and strength.

[0032] In some embodiments of the present application, the three-wave guardrail body 1 is manufactured using S750 zinc-aluminum-magnesium high-strength steel three-wave plates, which offer advantages such as simple structure, light weight, high strength, and quick installation. S750 zinc-aluminum-magnesium high-strength steel boasts significantly higher strength than existing Q235 / Q355 steel and possesses numerous advantages, including excellent plasticity, low-temperature toughness, plating suitability, and performance stability. Its mechanical properties include yield strength ≥700MPa, tensile strength ≥750MPa, and elongation ≥20%. Zinc-aluminum-magnesium high-strength steel improves its strength, cold bending properties, elongation, and low-temperature toughness. Its overall performance is superior to that of traditional Q235 / Q355 steel.

[0033] In summary: When the guardrail maintenance opening device is used, Figure 1 and Figure 2 As shown, when the staff needs to inspect or maintain the intelligent traffic monitoring facilities protected by the device, the staff removes the nut 11 threadedly connected to the screw rod 2 7, contacts the limit of the screw rod 2 7, and pulls the screw rod 2 7 upward until the screw rod 2 7 is separated from the limit plate 2 8. The three-wave opening door panel 2 is released, and the user pushes the three-wave opening door panel 2, and the three-wave opening door panel 2 rotates along the direction of the screw rod 1 5. The three-wave opening door panel 2 is opened, making it convenient for the staff to enter and exit the device. When the staff needs to close the three-wave opening door panel 2, the staff rotates the three-wave opening door panel 2 in the opposite direction. After the three-wave opening door panel 2 is reset, the screw rod 2 7 is used to simultaneously penetrate the connecting plate 2 6 and the limit plate 2 8, and then the nut 11 is used to fix the position of the screw rod 2 7, thereby achieving the closure of the three-wave opening door panel 2.
