Description

Technical Field

[0001] This invention relates to the field of bridge crash barrier technology, specifically the design and application of a multifunctional and environmentally friendly bridge crash barrier. Background Art

[0002] Bridge railings are guardrails installed on bridges to prevent out-of-control vehicles from going off the bridge. They serve to prevent vehicles from breaking through, passing under, or overturning the bridge, and also enhance the aesthetics of the bridge structure. The selection of bridge railing types should first be based on the highway grade, comprehensively considering factors such as safety, coordination, the characteristics of the protected object, and site geometry to determine the collision protection level. Then, the structural form should be selected based on factors such as the railing's structure, economy, construction, and maintenance. There are three installation methods: direct embedment of posts, flange connection, and casting the bridge railing and bridge deck into one piece using reinforcing steel bars.

[0003] Existing bridge crash barriers can only provide protection through their steel frame structure, resulting in a relatively simple overall function. They cannot provide additional safety protection, thus affecting their functionality. Furthermore, they do not offer any environmental protection benefits, leading to insufficient environmental performance. Summary of the Invention

The system is as follows: each of the three fixed columns has a connecting pipe inside, the bottom end of which passes through the collection box and is fixedly connected to the water outlet of the multi-port pipe; each of the three fixed columns has an atomizing nozzle fixedly connected to its outer surface, and the water outlet of each atomizing nozzle passes through to the outside of the fixed column; the tops of the three fixed columns are fixedly connected to a hollow tube, and three transparent covers are snapped into the inside of the hollow tube; three arc-shaped solar panels are installed inside the hollow tube, and the outer surface of each arc-shaped solar panel is in contact with the inner wall of the transparent cover; a protective box is fixedly connected to the back of the collection box, and a storage battery is fixedly connected to the inner bottom wall of the protective box; each of the ultraviolet germicidal lamps, the water pump, and each arc-shaped solar panel is electrically connected to the storage battery via wires.

[0006] Preferably, the front of the slide rail is fixedly connected with several fixing brackets, and the inner wall of each fixing bracket is fixedly connected to the outer surface of the crossbar.

[0007] Preferably, two limiting discs are fixedly connected to the outer surface of the winding rod, and the side of the two limiting discs that are close to each other is in contact with the outer surface of the cable.

[0008] Preferably, a hanging ring is fixedly connected to the end of the cable away from the winding rod, and an anti-detachment plate is fixedly connected to the end of the rectangular rod away from the sliding frame.

[0009] Preferably, a connecting plate is fixedly connected to the end of the rectangular rod away from the worm gear, and a handle is fixedly connected to the front side of the connecting plate.

[0012] Preferably, a reinforcing flange is fixedly connected to the outer surface of each of the fixed columns, the bottom surface of each of the reinforcing flanges is in contact with the upper surface of the bridge deck, and four fixing bolts are threaded to the inner wall of each of the reinforcing flanges, with the bottom end of each fixing bolt penetrating the reinforcing flange and extending into the interior of the bridge deck.

[0013] Preferably, each of the arc-shaped solar panels has a plurality of support frames fixedly connected to its inner wall, and the bottom surface of each support frame is fixedly connected to the inner wall of the hollow tube.

[0014] The design and application method of multifunctional and environmentally friendly bridge crash barriers includes the following steps: S1: When someone accidentally falls from the bridge into the water below and needs rescue, the rescuer can manually rotate the rectangular rod by holding the handle and using the connecting plate. When the rectangular rod rotates, the meshing of the worm gear and worm will drive the winding rod to rotate under the limit of the limiting plate. This will drive the cable and the life ring fixed on the hanging ring to move downwards until the rescue equipment reaches the position of the person in the water. Then, the rectangular rod can be rotated in the opposite direction to pull the person in the water up. The mechanical principle that the worm cannot drive the worm gear to rotate in the opposite direction can ensure the safety of rescuing the person in the water. S2: By sliding the sliding frame on the slide rail, the position of the cable on the bridge crash barrier can be adjusted so that it can be moved to the location of the person who has fallen into the water, increasing the convenience of rescuing the person who has fallen into the water. S3: When the sliding frame moves, the rectangular rod can be pushed backward to retract into the sliding frame, preventing the rectangular rod from affecting the left and right movement of the sliding frame. By using the rotation of the bearing in conjunction with the limiting frame and the rotating cylinder, the rectangular rod can move back and forth without affecting the rotation of the winding rod driven by the worm gear and worm. S4: By using the filter screen, rainwater on the bridge surface can be collected by entering the collection box through the drainage ditch and drainage pipe. When the weather is relatively dry and dust flies on the bridge surface, the suction provided by the water pump can be used to draw the rainwater collected in the collection box outward, and spray it outward from the atomizing nozzle with the help of the multi-port pipe and connecting pipe and the fixed column to suppress dust on the bridge surface. S5: Furthermore, by utilizing the special sterilizing light provided by the ultraviolet germicidal lamp, bacteria and germs in the collection box can be effectively killed, ensuring the safety of the sprayed water. At the same time, by using the curved solar panel with the protection of the transparent cover, solar energy can be converted into electrical energy and stored in the battery. Then, the battery and the protective box will supply the electrical energy to the water pump and the ultraviolet germicidal lamp, so that the operation of the water pump and the ultraviolet germicidal lamp does not require additional wiring.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: First, this invention, through the setting of a protective mechanism, allows for the manual rotation of a rectangular rod in conjunction with the rotation of a rotating cylinder and bearing, as well as the limiting frame, to drive the worm gear to rotate. When the worm gear rotates, it drives the winding rod to rotate via the worm, thereby enabling the winding and unwinding of the cable. This cable winding and unwinding facilitates the rescue of people who have accidentally fallen into the water below the bridge. Furthermore, utilizing the mechanical principle that the worm cannot drive the worm gear in the reverse direction, the safety of rescuing people who have fallen into the water is ensured. Then, by sliding the sliding frame on the slide rail, the position of the cable on the bridge crash barrier can be changed, facilitating the rescue of people who have fallen into the water from different positions. This increases the functionality of the bridge crash barrier, improves its safety protection effect, and facilitates the rescue of people who have fallen into the water.

[0016] Secondly, this invention, by setting up a water collection mechanism, can collect rainwater through drainage channels and pipes and store it in a collection box. When the weather is dry and the bridge surface is dusty, the suction provided by the water pump can draw the rainwater collected in the collection box outwards and spray it outwards from the atomizing nozzles through multi-channel pipes and connecting pipes, with the cooperation of fixed columns, to suppress dust on the bridge surface. In addition, the special sterilization light provided by the ultraviolet germicidal lamp can effectively kill bacteria and germs in the collection box, ensuring the safety of the sprayed water. At the same time, the use of curved solar panels with transparent covers can convert solar energy into electrical energy and store it in batteries, so that the operation of the water pump and ultraviolet germicidal lamp does not require additional wiring. This allows the bridge crash barrier to suppress dust on the bridge surface and increases the environmental protection performance of the bridge crash barrier. Attached Figure Description

A limiting frame 308 is fixedly connected to the back of the sliding frame 303. 7 is located inside the limiting frame 308. Two sets of bearings 309 are fixedly embedded in the inner wall of the limiting frame 308. There are two bearings in each set. A rotating cylinder 310 is fixedly connected to the inner wall of the inner ring of each set of bearings 309. A rectangular rod 311 is slidably connected inside the two rotating cylinders 310. A worm gear 312 is slidably connected to the outer surface of the rectangular rod 311. The worm gear 312 is located inside the limiting frame 308. The outer surface of the worm gear 312 meshes with the outer surface of the worm 307.

[0021] The front of the slide rail 301 is fixedly connected with several fixing brackets 14. The inner wall of each fixing bracket 14 is fixedly connected to the outer surface of the crossbar 2. The fixing brackets 14 can fix the position of the slide rail 301 on the crossbar 2 without affecting the normal use of the slide rail 301, thus ensuring the stability of the slide rail 301.

[0022] Two limiting discs 5 are fixedly connected to the outer surface of the winding rod 305. The side of the two limiting discs 5 that are close to each other is in contact with the outer surface of the cable 306. The limiting discs 5 can limit the position of the cable 306 on the winding rod 305, prevent the cable 306 from becoming loose from the winding rod 305, and improve the reliability of the cable 306.

[0023] A hanging ring 6 is fixedly connected to the end of the cable 306 away from the winding rod 305, and an anti-detachment plate 7 is fixedly connected to the end of the rectangular rod 311 away from the sliding frame 303. The hanging ring 6 can conveniently suspend rescue safety equipment, such as a safety rope or life ring, at one end of the cable 306, and the anti-detachment plate 7 can prevent the rectangular rod 311 from detaching from the limiting frame 308.

[0024] A connecting plate 8 is fixedly connected to the end of the rectangular rod 311 away from the worm gear 312. A handle 9 is fixedly connected to the front of the connecting plate 8. By manually holding the handle 9 and cooperating with the connecting plate 8, the user can easily rotate the rectangular rod 311, which increases the ease of rotation of the rectangular rod 311.

[0025] The specific implementation of this embodiment is as follows: When someone accidentally falls from the bridge surface 1 into the water below and needs rescue, the rescuer can manually rotate the rectangular rod 311 by holding the handle 9 and cooperating with the connecting plate 8. When the rectangular rod 311 rotates, the meshing of the worm gear 312 and the worm 307 will drive the winding rod 305 to rotate under the limit of the limiting plate 304. This will drive the cable 306 and the life ring fixed on the hanging ring 6 to move downwards until the rescue equipment reaches the position of the person in the water. Then, rotating the rectangular rod 311 in the opposite direction will pull the person in the water up. Furthermore, by utilizing the mechanical principle that the worm 307 cannot drive the worm gear 312 to rotate in the opposite direction, the safety of rescuing the person in the water can be ensured. In addition, the sliding frame 303... Sliding on the slide rail 301 allows adjustment of the position of the cable 306 on the bridge crash barrier, enabling it to be moved more easily to the location of the person in the water, increasing the convenience of rescue, enhancing the functionality of the bridge crash barrier, improving its safety protection effect, and facilitating the rescue of the person in the water. When the sliding frame 303 moves, it can push the rectangular rod 311 backward, causing the rectangular rod 311 to retract into the sliding frame 303, preventing the rectangular rod 311 from affecting the left and right movement of the sliding frame 303. By utilizing the rotation of the bearing 309 in conjunction with the limiting frame 308 and the rotating cylinder 310, the rectangular rod 311 can move back and forth without affecting the rotation of the winding rod 305 driven by the worm gear 312 and worm 307. Example

[0026] Please see Figure 1-6The water collection mechanism 4 includes a collection box 401. The upper surface of the collection box 401 is fixedly connected to the bottom surface of the bridge deck 1. A drainage channel 402 is formed on the upper surface of the bridge deck 1. Two drainage pipes 404 are fixedly connected to the inner wall of the drainage channel 402. The other ends of the two drainage pipes 404 penetrate the bridge deck 1 and extend to the outside of the bridge deck 1. Collection pipes 405 are fixedly connected to the outer surfaces of the two drainage pipes 404. The bottom ends of the two collection pipes 405 penetrate into the interior of the collection box 401. The inner top wall of the collection box 401 is fixedly connected to the bottom surface of the bridge deck 1. A number of ultraviolet germicidal lamps 411 are fixedly connected, each of which is covered with a waterproof transparent shell. A water pump 406 is fixedly connected to the inner bottom wall of the collection box 401, and the outlet of the water pump 406 is fixedly connected to a multi-port pipe 407. Three fixed posts 408 are fixedly connected to the upper surface of the collection box 401, and the top of each fixed post 408 extends to the top of the bridge deck 1. The outer surface of each fixed post 408 is fixedly connected to the outer surface of the crossbar 2. Each fixed post 408 has an internal structure. A connecting pipe 409 is provided, the bottom end of each connecting pipe 409 passing through the collection box 401 and fixedly connected to the water outlet of the multi-port pipe 407. An atomizing nozzle 410 is fixedly connected to the outer surface of each connecting pipe 409, and the water outlet of each atomizing nozzle 410 extends to the outside of the fixing column 408. A hollow tube 412 is fixedly connected to the top of the three fixing columns 408. Three transparent covers 413 are snapped into the inside of the hollow tube 412, and three arc-shaped solar panels 41 are installed inside the hollow tube 412. 4. The outer surface of each curved solar panel 414 is in contact with the inner wall of the transparent cover 413. A protective box 415 is fixedly connected to the back of the collection box 401. A storage battery 416 is fixedly connected to the inner bottom wall of the protective box 415. A voltage regulator is installed inside the storage battery 416 to stabilize the current generated by the curved solar panel 414 and ensure the normal operation of the charging work. Each ultraviolet germicidal lamp 411, water pump 406 and each curved solar panel 414 are electrically connected to the storage battery 416 through wires.

[0027] A filter screen 15 is fixedly connected to the inner wall of the drainage ditch 402. The filter screen 15 is set above the water inlet of the drainage pipe 404. The filter screen 15 can filter the rainwater entering the drainage ditch 402, prevent too many impurities from entering the drainage ditch 402, and make the drainage pipe 404 less likely to be blocked by impurities.

[0028] Two stabilizing seats 10 are fixedly connected to the outer surface of the multi-port pipe 407. The bottom surfaces of the two stabilizing seats 10 are fixedly connected to the inner bottom wall of the collection box 401. The stabilizing seats 10 can fix the position of the multi-port pipe 407 and increase the stability of the multi-port pipe 407.

[0029] Each fixed post 408 has a reinforcing flange 11 fixedly connected to its outer surface. The bottom surface of each reinforcing flange 11 is in contact with the upper surface of the bridge deck 1. Each reinforcing flange 11 has four fixing bolts 12 threadedly connected to its inner wall. The bottom end of each fixing bolt 12 passes through the reinforcing flange 11 and extends into the interior of the bridge deck 1. By using the reinforcing flange 11 in conjunction with the fixing bolts 12, the connection tightness between the fixed post 408 and the bridge deck 1 can be increased, so that the fixed post 408 has a better safety protection effect.

[0030] Each curved solar panel 414 has several support frames 13 fixedly connected to its inner wall. The bottom surface of each support frame 13 is fixedly connected to the inner wall of the hollow tube 412. The support frame 13 can support the curved solar panel 414, increase the stability of the curved solar panel 414 inside the hollow tube 412, and ensure that the curved solar panel 414 can receive sunlight normally.

[0031] The specific implementation of this embodiment is as follows: Using the filter screen 15, rainwater on the bridge surface 1 can be collected by flowing through the drainage ditch 402 and drainage pipe 404 from the collection pipe 405 into the collection box 401. When the weather is relatively dry, causing dust to fly on the bridge surface 1, the suction provided by the water pump 406 can draw the rainwater collected in the collection box 401 outwards, and through the multi-port pipe 407 and connecting pipe 409, with the cooperation of the fixed column 408, spray it outwards from the atomizing nozzle 410 to suppress dust on the bridge surface 1. Furthermore, the ultraviolet germicidal lamp 411 provides special... The special germicidal light can effectively kill bacteria and germs in the collection box 401, ensuring the safety of the sprayed water. At the same time, the curved solar panel 414, in conjunction with the protection of the transparent cover 413, can convert solar energy into electrical energy and store it in the battery 416. Then, the battery 416, in conjunction with the protective box 415, supplies the electrical energy to the water pump 406 and the ultraviolet germicidal lamp 411. This eliminates the need for additional wiring for the operation of the water pump 406 and the ultraviolet germicidal lamp 411, allowing the bridge crash barrier to suppress dust on the bridge surface 1 and increasing the environmental performance of the bridge crash barrier.

[0032] The working principle of this invention is as follows: When someone accidentally falls from the bridge surface 1 into the water below and needs rescue, the rescuer can manually rotate the rectangular rod 311 by holding the handle 9 and cooperating with the connecting plate 8. When the rectangular rod 311 rotates, the meshing of the worm gear 312 and the worm 307 drives the winding rod 305 to rotate under the limit of the limiting plate 304. This, in turn, drives the cable 306 and the lifebuoy fixed on the hanging ring 6, and other rescue equipment, to move downwards until the rescue equipment reaches the position of the person in the water. Then, rotating the rectangular rod 311 in the opposite direction can pull the person in the water up. Furthermore, by utilizing the mechanical principle that the worm 307 cannot drive the worm gear 312 to rotate in the opposite direction, the safety of rescuing the person in the water can be ensured. Then, the sliding frame 303 moves along the slide rail. The sliding mechanism 301 allows for adjustment of the position of the cable 306 on the bridge crash barrier, enabling it to be moved more easily to the location of the person in the water, thus increasing the convenience of rescue, enhancing the functionality of the bridge crash barrier, and improving its safety protection effect. When the sliding frame 303 moves, it can push the rectangular rod 311 backward, causing it to retract into the sliding frame 303, preventing it from affecting the left and right movement of the sliding frame 303. Furthermore, the rotation of the bearing 309, combined with the limiting mechanism 308 and the rotating cylinder 310, allows the rectangular rod 311 to move back and forth without affecting its ability to drive the winding rod 305 to rotate via the worm gear 312 and worm 307. Using filter 15, rainwater on bridge deck 1 can be collected by flowing through drainage ditch 402 and drainage pipe 404 into collection box 401 via collection pipe 405. When the weather is dry and dust flies on bridge deck 1, the suction provided by water pump 406 can draw the rainwater collected in collection box 401 outwards, and spray it outwards from atomizing nozzle 410 with the cooperation of multi-port pipe 407 and connecting pipe 409, thereby suppressing dust on bridge deck 1. Furthermore, the special sterilization light provided by ultraviolet germicidal lamp 411 is utilized. It can effectively kill bacteria and germs in the collection box 401, ensuring the safety of the sprayed water. At the same time, the curved solar panel 414, in conjunction with the protection of the transparent cover 413, can convert solar energy into electrical energy and store it in the battery 416. Then, the battery 416, in conjunction with the protective box 415, supplies the electrical energy to the water pump 406 and the ultraviolet germicidal lamp 411. This eliminates the need for additional wiring for the operation of the water pump 406 and the ultraviolet germicidal lamp 411, allowing the bridge crash guardrail to suppress dust on the bridge surface 1 and increasing the environmental performance of the bridge crash guardrail.

[0033] The design and application method of multifunctional and environmentally friendly bridge crash barriers includes the following steps: S1: When someone accidentally falls from the bridge deck 1 into the water below the bridge and needs rescue, the rescuer can manually hold the handle 9 and rotate the rectangular rod 311 with the connecting plate 8. When the rectangular rod 311 rotates, the meshing of the worm gear 312 and the worm 307 will drive the winding rod 305 to rotate under the limit of the limiting plate 304. This will drive the cable 306 and the life ring fixed on the hanging ring 6 to move downwards until the rescue equipment reaches the position of the person in the water. Then, the rectangular rod 311 can be rotated in the opposite direction to pull the person in the water up. The mechanical principle that the worm 307 cannot drive the worm gear 312 to rotate in the opposite direction can ensure the safety of the rescuer. S2: By sliding the sliding frame 303 on the slide rail 301, the position of the cable 306 on the bridge crash barrier can be adjusted so that it can be moved to the position of the person who fell into the water, increasing the convenience of rescuing the person who fell into the water. S3: When the sliding frame 303 moves, the rectangular rod 311 can be pushed backward to retract into the sliding frame 303, preventing the rectangular rod 311 from affecting the left and right movement of the sliding frame 303. By using the rotation of the bearing 309 in conjunction with the limiting frame 308 and the rotating cylinder 310, the rectangular rod 311 can move back and forth without affecting the rotation of the winding rod 305 driven by the worm gear 312 and worm 307. S4: By using the filter screen 15, rainwater on the bridge surface 1 can be collected by entering the collection box 401 through the collection pipe 405 via the drainage ditch 402 and the drainage pipe 404. When the weather is relatively dry and dust flies on the bridge surface 1, the suction provided by the water pump 406 can be used to draw the rainwater collected in the collection box 401 outward, and spray it outward from the atomizing nozzle 410 with the cooperation of the fixed column 408 through the multi-port pipe 407 and the connecting pipe 409 to suppress dust on the bridge surface 1. S5: Furthermore, the special sterilizing light provided by the ultraviolet germicidal lamp 411 can effectively kill bacteria and germs in the collection box 401, ensuring the safety of the sprayed water. At the same time, the curved solar panel 414, in conjunction with the protection of the transparent cover 413, can convert solar energy into electrical energy and store it in the battery 416. Then, the battery 416, in conjunction with the protective box 415, supplies the electrical energy to the water pump 406 and the ultraviolet germicidal lamp 411, so that the operation of the water pump 406 and the ultraviolet germicidal lamp 411 does not require additional wiring.

10. The design and application method of the multifunctional environmentally friendly bridge crash barrier according to any one of claims 1-9, characterized in that: Specifically, the following steps are included: S1: When someone accidentally falls from the bridge surface (1) into the water below the bridge and needs rescue, the rescuer can manually hold the handle (9) and rotate the rectangular rod (311) in conjunction with the connecting plate (8). When the rectangular rod (311) rotates, the meshing of the worm gear (312) and the worm (307) will drive the winding rod (305) to rotate under the limit of the limiting plate (304), which will drive the cable (306) and the life ring fixed on the hanging ring (6) to move downward until the rescue equipment is lowered to the position of the person in the water. Then, the rectangular rod (311) can be rotated in the opposite direction to pull the person in the water up. The mechanical principle that the worm (307) cannot drive the worm gear (312) to rotate in the opposite direction can ensure the safety of rescuing the person in the water. S2: By sliding the sliding frame (303) on the slide rail 301, the position of the cable (306) on the bridge crash barrier can be adjusted so that it can be moved to the position of the person who fell into the water, thereby increasing the convenience of rescuing the person who fell into the water. S3: When the sliding frame (303) moves, the rectangular rod (311) can be pushed backward to retract into the sliding frame (303) to prevent the rectangular rod (311) from affecting the left and right movement of the sliding frame (303). By using the rotation of the bearing (309) in conjunction with the limiting frame (308) and the rotating cylinder (310), the rectangular rod (311) can move back and forth without affecting the rectangular rod (311) driving the winding rod (305) to rotate through the worm gear (312) and worm (307). S4: By using the filter screen (15), rainwater on the bridge surface (1) can be collected by entering the collection box (401) through the collection pipe (405) via the drainage ditch (402) and drainage pipe (404). When the weather is relatively dry and dust flies on the bridge surface (1), the suction provided by the water pump (406) can be used to draw the rainwater collected in the collection box (401) outward and spray it outward from the atomizing nozzle (410) with the cooperation of the fixed column (408) through the multi-port pipe (407) and connecting pipe (409) to suppress dust on the bridge surface (1). S5: Furthermore, by utilizing the special sterilizing light provided by the ultraviolet germicidal lamp (411), bacteria and germs in the collection box (401) can be effectively killed, ensuring the safety of the sprayed water. At the same time, by utilizing the arc-shaped solar panel (414) in conjunction with the protection of the transparent cover (413), solar energy can be converted into electrical energy and stored in the battery (416). Then, the battery (416) in conjunction with the protective box (415) supplies the electrical energy to the water pump (406) and the ultraviolet germicidal lamp (411), so that the operation of the water pump (406) and the ultraviolet germicidal lamp (411) does not require additional wiring.
