Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of bridge deck heating devices, specifically relating to a pedestrian bridge deck that can be heated and thawed. Background Technology
[0002] A type of pedestrian bridge deck capable of being heated and thawing refers to a special bridge deck structure that integrates active heating functions to eliminate ice and snow cover. Its core lies in transforming the bridge deck from a traditional passive load-bearing component into a composite functional body with active thermal response capabilities. This structure mainly consists of heating elements (such as carbon fiber heating wires, heating cables, or conductive concrete layers incorporating conductive minerals such as iron ore), an intelligent temperature control system (including temperature sensors and automatic controllers), and a structural protective layer. Its working principle is as follows: when the ambient temperature is below a preset threshold (e.g., 2°C) and there is snow on the bridge surface, the system automatically activates, using electrical energy to drive the heating layer to generate heat. This heat is rapidly transferred to the bridge surface through a heat-conducting medium, melting the ice and snow and preventing pedestrians from slipping. This design effectively avoids the corrosion of bridge structures caused by traditional salting for de-icing and the lag of manual snow removal. It features a high degree of automation, high snow-melting efficiency, and all-weather pedestrian safety, making it an important component of modern intelligent transportation infrastructure.
[0003] The existing pedestrian bridge surface heating devices have a relatively simple structural design. Although they can automatically melt the ice and snow on the bridge surface, the melted water still adheres to the surface, making it easy for people to slip and fall. Furthermore, the design is not intelligent enough, requiring staff to observe and manually activate the device to heat and melt the ice and snow, which affects pedestrian traffic. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a pedestrian bridge surface that can be heated and thawed.
[0005] The technical solution adopted to solve the above technical problems is: a pedestrian bridge surface that can be heated and thawed, including a bridge body assembly, an energy storage control mechanism installed on one side of the bridge body assembly, and a heating mechanism installed in the center of the bridge body assembly; A drainage mechanism is installed on the bridge assembly above the heating mechanism, and a sweeping mechanism is installed on the surface of the bridge assembly to remove water from melting snow and ice.
[0006] Furthermore, the bridge assembly includes two piers, with a bridge fixedly connected to the top of the two piers. A bridge deck is laid on the top of the bridge. Bridge ladders are fixedly installed on both sides of the front end of the bridge. A railing is fixedly installed on the top of the bridge deck, and a canopy is fixedly installed on the top of the bridge deck.
[0007] With the above technical solution, pedestrians can enter the bridge deck through the bridge stairs on one side and exit through the bridge stairs on the other side. The canopy can also block rain and snow to a certain extent, preventing a large amount of rain and snow from accumulating on the bridge deck, thus providing convenience for pedestrians.
[0008] Furthermore, the energy storage control mechanism includes two solar panels fixedly installed on the roof, a box fixedly installed on one side of one of the bridge piers, an energy storage battery and a controller installed inside the box, a first wire fixedly connected to both solar panels and the energy storage battery, and a door installed on one side of the box.
[0009] Through the above technical solution, the two solar panels can absorb solar energy during the day and automatically convert it into electrical energy, which is stored in the energy storage battery through the first wire. When the heating mechanism needs to be used, it can be powered by the energy storage battery, thereby reducing the dependence on the municipal power grid and reducing the cost of use. The controller can automatically control the switching operation of the entire equipment, and the staff can remotely control it through the controller to realize the automatic heating and defrosting treatment of the bridge deck.
[0010] Furthermore, the heating mechanism includes a heating cable installed on the top of the bridge, a second conductor fixedly connected between the heating cable and the energy storage battery, a steel wire mesh on the top of the heating cable, the heating cable and the steel wire mesh being located between the bridge and the bridge deck, and the heating cable and the steel wire mesh being connected by wires.
[0011] With the above technical solution, when heating the bridge deck, the energy storage battery transmits power to the heating cable through the second conductor, so that the heating cable is energized and heated. At the same time, the heating cable transmits the current to the steel wire mesh through the wire, so that the steel wire mesh transmits the current to multiple iron ore, so that the multiple iron ore are energized and heated, thereby transferring heat energy to the bridge deck, realizing dual heating of the bridge deck and improving the efficiency of thawing ice and snow.
[0012] Furthermore, the wire mesh contains several iron ore particles.
[0013] Through the above technical solution, iron ore has good electrical conductivity, thus generating heat quickly and rapidly heating the bridge deck to achieve rapid thawing.
[0014] Furthermore, the drainage mechanism includes multiple drainage pipes installed inside the bridge deck, with connecting pipes fixedly connected between the multiple drainage pipes, and a water inlet pipe fixedly connected to one side of the connecting pipe, the water inlet pipe being located on one side of one of the bridge stairs.
[0015] With the above technical solution, when the ice and snow on the bridge surface thaw, the water generated flows into the connecting pipe through multiple drainage pipes, and then is discharged to the outside of the bridge through the water inlet pipe, preventing water from adhering to the bridge surface, thereby preventing people from slipping and providing safety for people.
[0016] Furthermore, the sweeping mechanism includes a guide rail fixedly connected to the rear end of the top of the bridge deck, a rack fixedly connected to the bottom front end of the guide rail, a slide plate slidably connected to the guide rail, a pulley installed at the bottom front end of the slide plate, the pulley slidably connected to the top of the bridge deck, a brush fixedly installed at the bottom center of the slide plate, a servo motor fixedly installed at the bottom rear end of the slide plate, and a gear fixedly connected to the outer wall of the output shaft of the servo motor, the gear meshing with the rack.
[0017] With the above technical solution, after the ice water on the bridge surface thaws, the servo motor is started, and the output shaft rotates to drive the gears to rotate. The gears mesh and roll on the rack, and with the help of the pulleys, the slide plate moves, which in turn moves the brush. The brush sweeps across the bridge surface, removing the water attached to the surface and achieving rapid dehumidification. This prevents the thawed water from accumulating for a long time and affecting pedestrian traffic, thus improving the safety of pedestrian travel.
[0018] Furthermore, two temperature sensors are installed on the fence.
[0019] The above technical solution uses two temperature sensors to monitor the surface temperature of the bridge deck at all times. If the temperature is lower than the designed range, the information is transmitted to the controller, which then automatically starts the heating mechanism to automatically heat the bridge deck. Staff can observe the process remotely without having to go to the site, which greatly reduces labor costs.
[0020] The beneficial effects of the present invention are as follows: (1) The present invention can automatically drain the thawed water out of the bridge by designing a drainage mechanism and a sweeping mechanism, and at the same time automatically clean the water attached to the bridge surface to prevent water from adhering to the bridge surface, thereby preventing people from slipping and providing safety protection for people; (2) The present invention can monitor the surface temperature of the bridge surface at all times by designing a temperature sensor. If the temperature is lower than the designed range, the information is transmitted to the controller, and the controller will automatically start the heating mechanism to realize automatic heating treatment of the bridge surface. The staff can observe through remote equipment without having to go to the site to operate, which greatly reduces labor costs. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0024] like Figures 1-7 As shown, this embodiment of a heatable and thawing pedestrian bridge includes a bridge body assembly 1, which includes two piers 101. A bridge 102 is fixedly connected to the top of the two piers 101. A bridge deck 103 is laid on top of the bridge 102. Bridge stairs 104 are fixedly installed on both sides of the front end of the bridge 102. A railing 105 is fixedly installed on the top of the bridge deck 103, and a canopy 106 is fixedly installed on the top of the bridge deck 103. Pedestrians can enter the bridge deck 103 via one side of the bridge stairs 104 and exit via the other side of the bridge stairs 104. The canopy... 106 can block rain and snow to a certain extent, preventing a large amount of rain and snow from accumulating on the bridge surface 103, thus facilitating pedestrian travel. Two temperature sensors 6 are installed on the fence 105. The two temperature sensors 6 monitor the surface temperature of the bridge surface 103 at all times. If the temperature is lower than the designed range, the information is transmitted to the controller 205. The controller 205 then automatically starts the heating mechanism 3 to automatically heat the bridge surface 103. Staff can observe the process through remote equipment without having to go to the site, which greatly reduces labor costs.
[0025] like Figures 1-5As shown, an energy storage control mechanism 2 is installed on one side of the bridge body component 1. The energy storage control mechanism 2 includes two solar panels 201 fixedly installed on the roof 106. A box 202 is fixedly installed on one side of one of the bridge piers 101. An energy storage battery 203 and a controller 205 are installed inside the box 202. The two solar panels 201 are fixedly connected to the energy storage battery 203 by a first wire 204. A box door 206 is installed on one side of the box 202. The two solar panels 201 can absorb solar energy during the day and automatically convert it into electrical energy, which is stored in the energy storage battery 203 through the first wire 204. When the heating mechanism 3 needs to be used, it can be powered by the energy storage battery 203, thereby reducing the dependence on the municipal power grid and reducing the operating cost. The controller 205 can automatically control the switching operation of the entire equipment. The staff can remotely control the bridge surface 103 through the controller 205 to achieve automatic heating and defrosting treatment.
[0026] like Figures 1-4 As shown, a heating mechanism 3 is installed at the center of the bridge assembly 1. The heating mechanism 3 includes a heating cable 301 located at the top of the bridge 102. A second conductor 303 is fixedly connected between the heating cable 301 and the energy storage battery 203. A steel wire mesh 302 is provided at the top of the heating cable 301. Both the heating cable 301 and the steel wire mesh 302 are located between the bridge 102 and the bridge deck 103. The heating cable 301 and the steel wire mesh 302 are connected by wires. When the bridge deck 103 is heated, the energy storage battery 203 is heated by the second conductor 303. 03 supplies power to the heating cable 301, enabling it to heat up. Simultaneously, the heating cable 301 transmits current through wires to the steel wire mesh 302, which in turn transmits the current to multiple iron ore particles. These particles then heat up, transferring heat energy to the bridge deck 103, thus achieving dual heating of the bridge deck and improving the efficiency of ice and snow thawing. The steel wire mesh 302 contains several iron ore particles, which have good electrical conductivity, allowing them to heat up quickly and rapidly thaw the bridge deck 103.
[0027] like Figures 1-4 As shown, a drainage mechanism 4 is installed on the bridge body component 1 above the heating mechanism 3. The drainage mechanism 4 includes multiple drainage pipes 401 installed inside the bridge deck 103. A connecting pipe 402 is fixedly connected between the multiple drainage pipes 401. A water inlet pipe 403 is fixedly connected to one side of the connecting pipe 402. The water inlet pipe 403 is located on one side of one of the bridge stairs 104. When the ice and snow on the bridge deck 103 thaw, the water generated flows into the connecting pipe 402 through the multiple drainage pipes 401 and is then discharged to the outside of the bridge through the water inlet pipe 403, preventing water from adhering to the bridge deck 103, thereby preventing people from slipping and providing safety for people.
[0028] like Figures 1-6As shown, a sweeping mechanism 5 is installed on the surface of the bridge body assembly 1. The sweeping mechanism 5 removes water from the melting snow and ice. The sweeping mechanism 5 includes a guide rail 501 fixedly connected to the rear end of the top of the bridge surface 103. A rack 502 is fixedly connected to the bottom front end of the guide rail 501. A slide plate 503 is slidably connected to the guide rail 501. A pulley 504 is installed at the front bottom of the slide plate 503. The pulley 504 is slidably connected to the top of the bridge surface 103. A brush 505 is fixedly installed at the center bottom of the slide plate 503. A servo motor 506 is fixedly installed at the rear bottom of the slide plate 503. The outer wall of the output shaft of the servo motor 506 is fixed. A gear 507 is connected, and the gear 507 meshes with the rack 502. When the ice water on the bridge surface 103 thaws, the servo motor 506 is started. The output shaft rotates, driving the gear 507 to rotate, so that the gear 507 meshes and rolls on the rack 502. With the cooperation of the pulley 504, the slide plate 503 is moved, which in turn moves the brush 505, causing the brush 505 to sweep on the bridge surface 103, thereby sweeping away the water attached to the surface of the bridge surface 103. This achieves rapid dehumidification of the surface of the bridge surface 103, prevents the thawed water from accumulating for a long time and affecting the passage of people, and improves the safety of people's travel.
[0029] The working principle of this embodiment is as follows: when the temperature sensor 6 detects that the temperature of the bridge deck 103 is low, the temperature sensor 6 transmits the information to the controller 205, and the controller 205 automatically starts the heating mechanism 3. At this time, the energy storage battery 203 transmits power to the heating cable 301 through the second wire 303, so that the heating cable 301 is energized and heated. At the same time, the heating cable 301 transmits the current to the steel wire mesh 302 through the wire, so that the steel wire mesh 302 transmits the current to multiple iron ore, so that the multiple iron ore are energized and heated, thereby transferring the heat energy to the bridge deck 103 and realizing the dual heating of the bridge deck. When the ice and snow on the bridge surface 103 thaw, the resulting water flows into the connecting pipe 402 through multiple drainage pipes 401, and then is discharged to the outside of the bridge through the water inlet pipe 403 to prevent water from adhering to the bridge surface 103. At the same time, the servo motor 506 is started, and the output shaft rotates to drive the gear 507 to rotate, so that the gear 507 meshes and rolls on the rack 502. With the cooperation of the pulley 504, the sliding plate 503 is moved, which in turn moves the brush 505, causing the brush 505 to sweep on the bridge surface 103, thereby sweeping away the water adhering to the surface of the bridge surface 103. This achieves rapid dehumidification of the surface of the bridge surface 103, prevents the thawed water from accumulating for a long time and affecting the passage of people, and improves the safety of people's travel. Two solar panels 201 can absorb solar energy during the day and automatically convert it into electrical energy, which is stored in the energy storage battery 203 through the first wire 204. When the heating mechanism 3 needs to be used, it can be powered by the energy storage battery 203, thereby reducing dependence on the municipal power grid and reducing the cost of use.
[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
