Description

Technical Field

[0001] This utility model relates to the field of highway bridge technology, and in particular to a winter snow removal and anti-skid device for highway bridges. Background Technology

[0002] Snow accumulation and icing on highway bridges in winter is a common and serious problem. When winter arrives, snowfall and low temperatures cover bridge surfaces with snow. If the snow is not cleared in time, it easily forms ice layers after being run over by vehicles. This not only reduces the friction of vehicles and increases braking distance, making traffic accidents more likely and threatening people's travel safety, but also causes freeze-thaw damage to the bridge structure, shortening the bridge's service life. Currently, common methods for snow removal and anti-skid measures on highway bridges in winter have many drawbacks. For example, while spraying de-icing agents is highly efficient, the chemicals in the agents can corrode the steel bars in the bridge structure and pollute the soil and water sources. Mechanical snow removal requires a large investment of manpower and resources, and its efficiency is limited and not energy-saving. It is difficult to achieve ideal snow removal results for some complex bridge structures and parts, and it may also damage the bridge surface. Therefore, to address the above problems, a snow removal and anti-skid device for highway bridges in winter is proposed. Utility Model Content

[0003] The technical problem to be solved by this utility model overcomes the existing defects and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A winter snow removal and anti-skid device for highway bridges includes a bracket. A multi-stage electric push rod is fixedly connected to the top inner side of the bracket. A slider, slidably connected to the bracket, is located at the bottom outer side of the multi-stage electric push rod. A box body, in contact with the bracket, is fixedly connected to one end of the slider. A box cover with a through hole on the outside is hinged to the top of the box body. A return pipe is connected to one side of the top of the box cover, and a fixed pipe is connected to the other end of the return pipe. A connecting pipe is connected to the top of the fixed pipe. A solar collector is fixedly connected to the bottom outer side of the box body via a connecting block, and the other end of the connecting pipe is connected to the outlet pipe of the solar collector. A delivery pipe is connected to the inlet pipe of the solar collector, and the other end of the delivery pipe is connected to the box body. A heat-conducting pipe made of copper is connected to one end of the fixed pipe. A battery is fixedly connected to one side of the bottom of the box body, and a controller is fixedly connected to the other side of the bottom of the box body. A solar panel is fixedly connected to the front end of the box body via a connecting block.

[0006] As a further improvement of this utility model, bolts are provided at both the upper and lower ends of the bracket, and the bolts penetrate the bracket and are spirally connected to the bracket.

[0007] As a further improvement of this utility model, a control switch is fixedly connected to one side of the top of the slider, and the control switch on one side is in contact with the corresponding bracket.

[0008] As a further improvement of this utility model, a temperature sensor is fixedly connected to one end of the inner side of the fixed tube, and an electric heating rod is fixedly connected to the center of the inner side of the fixed tube through a connecting block.

[0009] As a further improvement of this utility model, the bottom end of the multi-stage electric push rod is fixedly connected to a fixing block that contacts the slider, and the top end of the fixing block is fixedly connected to a pressure sensor that contacts the slider.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. A winter snow removal and anti-skid device for highway bridges, consisting of a housing, multi-stage electric actuators, sliders, solar collectors, electric heating rods, fixed pipes, and heat-conducting pipes, works by retracting one multi-stage electric actuator on one side, triggering a control switch to activate the corresponding temperature sensor and electric heating rod. Simultaneously, the other multi-stage electric actuator extends, causing antifreeze in the higher housing to flow through a delivery pipe to the corresponding solar collector for heating. The heated antifreeze then flows through a connecting pipe into the fixed pipe. The temperature sensor monitors the temperature of the heated antifreeze, and finally, the electric heating rods provide additional heat. The system employs a heating-assisted process: after the antifreeze is heated, it flows through a copper heat pipe to heat the bridge surface, then flows into a fixed pipe on the other side, and finally returns to the lower box on the other side through a return pipe. This achieves snow removal and anti-skid treatment of the highway bridge after heating. Solar collectors utilize solar energy to heat the antifreeze, and then, under the sensing of a temperature sensor, electric heating rods provide auxiliary heating. The heated antifreeze then flows through the copper heat pipe to heat the bridge surface for snow removal and anti-skid treatment, resulting in better snow removal and anti-skid effects. This method is not only more energy-efficient, reducing manpower and material resources, and ensuring snow removal efficiency, but also prevents damage to the bridge, leading to better snow removal results.

[0012] 2. The winter snow removal and anti-skid device for highway bridges utilizes a multi-stage electric push rod, slider, fixing block, and pressure sensor. Antifreeze in the higher side tank is heated and flows through a heat pipe to heat the bridge for snow removal and anti-skid purposes. As it flows back to the lower side tank, the antifreeze level decreases in the higher tank and increases in the lower tank. This causes the pressure on the corresponding pressure sensor in the slider on one side to decrease, while the pressure on the corresponding pressure sensor in the slider on the other side increases. When both pressure sensors reach their set ranges, the multi-stage electric push rod on one side extends to lower the higher tank to its lowest position, while the multi-stage electric push rod on the other side retracts to raise the lower tank to its highest position. This facilitates the continuous circulation of heated antifreeze through the heat pipe to heat the bridge for snow removal and anti-skid purposes, ensuring a sustained snow removal and anti-skid effect.

[0020] Example 1

[0021] like Figure 1-4 As shown, a winter snow removal and anti-skid device for highway bridges includes a bracket 1. A multi-stage electric push rod 3 is fixedly connected to the top inner side of the bracket 1. A slider 4, slidably connected to the bracket 1, is located at the bottom outer side of the multi-stage electric push rod 3. A box 5, in contact with the bracket 1, is fixedly connected to one end of the slider 4. A box cover 6 with a through hole on its outer side is hinged to the top of the box 5. A return pipe 7 is connected to one side of the top of the box cover 6, and a fixed pipe 8 is connected to the other end of the return pipe 7. A connecting pipe 9 is connected to the top of the fixed pipe 8. The outer side of the box 5... A solar collector 10 is fixedly connected to the bottom of one side via a connecting block, and the other end of the connecting pipe 9 is connected to the water outlet pipe of the solar collector 10. The water inlet pipe of the solar collector 10 is connected to a conveying pipe 11, and the other end of the conveying pipe 11 is connected to the housing 5. A heat-conducting pipe 15 made of copper tube is connected to one end of the fixed pipe 8. A storage battery 16 is fixedly connected to one side of the bottom of the housing 5, and a controller 17 is fixedly connected to the other side of the bottom of the housing 5. A solar panel 18 is fixedly connected to the front end of the housing 5 via a connecting block.

[0022] Example 2

[0023] like Figure 1-2 As shown, in order to solve the problem of the inconvenience of installing the bracket 1 on the bridge, the bracket 1 is provided with bolts 2 at both the upper and lower ends, and the bolts 2 penetrate the bracket 1. The bolts 2 are spirally connected to the bracket 1. By setting the bolts 2 to spirally connect the bracket 1 and the bridge, it is convenient to install the bracket 1 on the bridge.

[0024] Example 3

[0025] like Figure 2 and Figure 4As shown, in order to solve the problem that it is inconvenient to activate the temperature sensor 12 and electric heating rod 13 on the corresponding side after the box 5 on the control side is raised, a control switch 14 is fixedly connected to one side of the top of the slider 4, and the control switch 14 on one side is in contact with the corresponding bracket 1. After the box 5 on the control side is raised, the control switch 14 on the corresponding side is triggered by the slider 4 on the corresponding side being raised at the same time, which facilitates the activation of the temperature sensor 12 and electric heating rod 13 on the corresponding side.

[0026] Example 4

[0027] like Figure 2-3 As shown, in order to solve the problem of inconvenience in detecting and assisting the heating of the antifreeze after the solar collector 10 is heated, a temperature sensor 12 is fixedly connected to one end of the inner side of the fixed tube 8, and an electric heating rod 13 is fixedly connected to the center of the inner side of the fixed tube 8 through a connecting block. By setting the temperature sensor 12 to detect the temperature of the antifreeze after the solar collector 10 is heated, the electric heating rod 13 is activated to assist heating when the temperature is not up to standard, which facilitates the detection and assisting heating of the antifreeze after the solar collector 10 is heated.

[0028] Example 5

[0029] like Figure 4 As shown, to address the issue of the difficulty in circulating and controlling the flow of heated antifreeze through the heat pipe 15 for heating, snow removal, and anti-skid purposes on highway bridges, the bottom of the multi-stage electric push rod 3 is fixedly connected to a fixed block 19 that contacts the slider 4. The top of the fixed block 19 is fixedly connected to a pressure sensor 20 that contacts the slider 4. During the process of controlling the flow of heated antifreeze through the heat pipe 15 for heating, snow removal, and anti-skid purposes on the highway bridge, as the antifreeze in the higher side tank 5 decreases and the antifreeze in the lower side tank 5 increases, the pressure on the corresponding pressure sensor 20 from the fixed block 19 within the slider 4 continuously decreases. The pressure of the corresponding fixed block 19 on the other side slider 4 continuously increases. When the pressure values ​​sensed by the pressure sensor 20 on one side and the pressure values ​​sensed by the pressure sensor 20 on the other side both reach the set range, the multi-stage electric push rod 3 on one side extends to control the lower side box 5 to descend to the lower position, and the multi-stage electric push rod 3 on the other side retracts to control the lower side box 5 to rise to the higher position. When the antifreeze in the other side box 5 is heated and flows through the heat pipe 15, and then flows back to the box 5 on one side, it facilitates the circulation control of the antifreeze flowing through the heat pipe 15 after heating to heat the highway bridge for snow removal and anti-skid.

[0030] In this embodiment, when using the device in winter, during the bridge construction process, a copper heat-conducting pipe 15 is laid on the inner side of the bridge deck. After the bridge construction is completed, the bracket 1 is fixed to the bridge using bolts 2. Then, the fixing pipe 8 and the heat-conducting pipe 15 are connected together by welding or other existing connection methods. When using the device to remove snow and prevent slippage on the highway bridge, the sensing range of the pressure sensor 20 and the temperature sensor 12 is preset by the controller 17. After setting, the device can be used. At this time, the multi-stage electric push rod 3 on one side retracts, driving the corresponding slider 4 to trigger the corresponding control switch 14. At this time, the temperature sensor 12 on the corresponding side... The corresponding electric heating rod 13 on one side will be activated, raising the corresponding housing 5 to a higher position. Simultaneously, the multi-stage electric push rod 3 on the other side will extend, lowering the housing 5 to a lower position. At this time, the antifreeze in the higher housing 5 will flow through the corresponding delivery pipe 11 to the corresponding solar collector 10 for heating, and then flow through the corresponding connecting pipe 9 into the corresponding fixed pipe 8. Next, the temperature sensor 12 will sense the temperature of the heated antifreeze. Finally, if the temperature does not meet the requirements, the corresponding electric heating rod 13 will assist in heating. The heated antifreeze will then flow through the copper heat-conducting pipe 15 to heat the bridge, and then flow into the fixed pipe 8 on the other side. When the antifreeze in the higher box 5 is heated and flows through the heat pipe 15 to the lower box 5, it is used to heat the highway bridge for snow removal and anti-skid treatment. As the antifreeze in the higher box 5 decreases and the antifreeze in the lower box 5 increases, the pressure on the corresponding pressure sensor 20 decreases through the fixed block 19 in one slider 4, while the pressure on the corresponding pressure sensor 20 increases through the fixed block 19 in the other slider 4. The pressure values ​​sensed by the pressure sensor 20 on one side and the other side are then compared. When the pressure values ​​sensed by the pressure sensor 20 on one side reach the set range, the multi-stage electric push rod 3 on one side extends to control the lower side of the housing 5 to descend to the lowest position, while the multi-stage electric push rod 3 on the other side retracts to control the lower side of the housing 5 to rise to the highest position. The antifreeze flows into the solar collector 10 on the other side through the delivery pipe 11 on the other side for heating, and then, under the sensing of the temperature sensor 12 on the other side, it is assisted by the electric heating rod 13 on the other side. Then, the above operation is repeated to flow through the heat pipe 15 again to heat the highway bridge for snow removal and anti-skid. This facilitates the circulation control of the antifreeze after heating and flowing through the heat pipe 15 to heat the highway bridge for snow removal and anti-skid, thereby ensuring the continuous snow removal and anti-skid effect of the highway bridge.
