[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-4 This utility model provides a technical solution: a protective device suitable for bridge piers of river bridges, including a steel plate 1, a protective baffle 2 and a buffer mechanism 3. The protective baffle 2 is installed in front of the steel plate 1 or in front of the steel plate 1. The buffer mechanism 3 is provided at the front end of the steel plate 1 and the protective mechanism 4 is provided at the front end of the protective baffle 2. The buffer mechanism 3 includes a support plate 301 and a shock absorber 302. The support plate 301 is fixedly installed at the front end of the mounting steel plate 1. The support plates 301 are evenly distributed at the front end of the mounting steel plate 1. The shock absorber 302 is fixedly installed at the front end of the support plate 301. A sealing piston 303 is movably installed at the front end of the shock absorber 302. The front end of the sealing piston 303 is fixedly connected to the rear end of the protective baffle 2. A shock absorber spring 304 is fixedly installed in the middle of the mounting steel plate 1 and the protective baffle 2. The shock absorber spring 304 is located at the outer end of the shock absorber 302 and the sealing piston 303. The mounting steel plate 1 squeezes the sealing piston 303 and compresses the shock absorber spring 304 at the same time. The shock absorber spring 304 drives the sealing piston 303 to extend and retract on the shock absorber 302.
[0018] The protective mechanism 4 includes an anti-collision rubber pad 401 and a reflective strip 402. The anti-collision rubber pad 401 is fixedly installed at the front end of the protective baffle 2, and the reflective strip 402 is fixedly installed at the front end of the anti-collision rubber pad 401. A protective composite plate layer 403 is provided at the front end of the inner end of the protective baffle 2. A reinforcing steel plate layer 404 is provided at the inner end of the protective baffle 2, located at the rear end of the protective composite plate layer 403. A fireproof layer 405 is provided at the inner end of the protective baffle 2, located at the rear end of the reinforcing steel plate layer 404. A stainless steel support layer 406 is provided at the inner end of the protective baffle 2, located at the rear end of the fireproof layer 405. An anti-corrosion layer 407 is provided at the inner end of the protective baffle 2. At the rear end of the stainless steel support layer 406, a mounting plate 408 is fixedly installed at the front end of the mounting steel plate 1. A waterproof audible and visual alarm 409 is fixedly installed at the left end of the front end of the mounting plate 408. A waterproof pressure sensor 410 is fixedly installed at the front end of the mounting steel plate 1. The waterproof pressure sensor 410 is electrically connected to the waterproof audible and visual alarm 409. The reflective strip 402 serves as a warning and protection function, and the anti-collision rubber pad 401 effectively reduces the impact force. The mounting steel plate 1 applies pressure to the waterproof pressure sensor 410. When the pressure value of the waterproof pressure sensor 410 exceeds the preset value, the waterproof pressure sensor 410 transmits data to the waterproof audible and visual alarm 409, which then issues an alarm.
[0019] A connecting hole 5 is provided at the right end of the mounting steel plate 1, a connecting rod 6 is fixedly installed at the left end of the mounting steel plate 1, and a number of mounting screw holes 7 are evenly provided at the front end of the mounting steel plate 1. A mounting bolt 8 is threadedly connected inside the connecting hole 5 on one side of the mounting steel plate 1, and the mounting bolt 8 passes through the connecting hole 5.
[0020] Working principle: When it is necessary to protect the piers of a river bridge, first screw the mounting bolts 8 into the mounting screw holes 7 on the mounting steel plate 1, and then screw it onto the bridge. Install the mounting steel plate 1 on the bridge. If it is not wide enough, the connecting rod 6 on another mounting steel plate 1 can be inserted into the connecting hole 5 on the installed mounting steel plate 1 for multiple pieces to be spliced together. The reflective strip 402 serves as a warning and protection function, and the anti-collision rubber pad 401 effectively reduces the impact force for protection. The reinforcement steel plate layer 404 and the stainless steel support layer 406 effectively provide support and protection. When impacted, the mounting steel plate... Plate 1 presses against the sealing piston 303 and simultaneously compresses the shock-absorbing spring 304. The shock-absorbing spring 304 drives the sealing piston 303 to extend and retract on the shock-absorbing damper 302, thus damping and buffering the impact force and reducing the severity of the collision accident. At the same time, the installation plate 1 applies pressure to the waterproof pressure sensor 410. When the pressure value of the waterproof pressure sensor 410 exceeds the preset value, the waterproof pressure sensor 410 transmits data to the waterproof audible and visual alarm 409, which then sounds an alarm to alert pedestrians, allowing for timely and effective alarm and rescue operations.
[0021] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
