Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge drainage, in particular to a snow melting and drainage device for bridges. Background Art
[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.
[0003] The guardrail of the upper structure of the bridge structure forms a U-shaped structure with the bridge deck. The precipitation in the bridge road surface mainly relies on the roadside horizontal drainage pipes and vertical drainage pipes to discharge the road surface limit.
[0004] In the north, there is concentrated snowfall in winter, and the accumulated snow cannot be cleared in time, causing ice and snow to block the drainage holes of the bridge beams; if snow removal equipment is used to sweep the accumulated snow onto the hard shoulder and pile it up, it will more easily aggravate the blockage; due to insufficient light and temperature in the north, especially for east-west bridges, the south side guardrails do not provide sufficient sunlight, which makes it easy for ice to accumulate after snow, resulting in the failure of the edge drainage function.
[0005] In some places, the hard shoulders of roads are mainly used by non-motor vehicles, and the accumulated snow poses a serious traffic safety hazard; when the drainage holes freeze, icicles are formed, and their own weight affects the safety of the drainage pipes, and it is easy to cause secondary damage to vehicles and personnel under the bridge. Utility Model Content
[0006] In view of the shortcomings of the prior art, the purpose of the embodiments of the present utility model is to provide a snow melting and drainage device for bridges to solve the problem of snow and ice accumulation on the hard shoulders of bridges.
[0007] In order to achieve the above objectives, the present invention provides the following technical solutions:
[0008] A snow melting and drainage device for a bridge, comprising:
[0009] Drain pipes are installed on the shoulder or curb of the bridge near the guardrail or at the bottom of the guardrail;
[0010] The first heat conducting pipe groove is arranged at the junction of the road surface and the guardrail of the shoulder or curb;
[0011] A heat pipe is installed in the first heat pipe groove, and includes a heating resistor wire inside the heat pipe to generate heat and melt nearby ice and snow;
[0012] The transverse cable channel is a through hole that crosses the guardrail. Wires are arranged in the cable channel, and the heating device is connected to the power supply through the wires.
[0013] In some embodiments, the drainage pipe includes a transverse drainage pipe and a vertical drainage pipe. The vertical drainage pipe is arranged on the shoulder or curb of the bridge and is a through hole passing through the bridge deck. The transverse drainage pipe is arranged at the bottom of the guardrail and is a through hole passing across the guardrail.
[0014] In some embodiments, a second heat-conducting pipe groove is further provided, and the second heat-conducting pipe groove connects the first heat-conducting pipe groove and the drain pipe. A heat-conducting pipe is also provided in the second heat-conducting pipe groove to heat the drain pipe.
[0015] In some embodiments, a heat conducting pipe is provided in the horizontal drain pipe and the vertical drain pipe, and the heat conducting pipe runs through the horizontal drain pipe and the vertical drain pipe.
[0016] In some embodiments, the heat pipe is a long tubular structure and is made of a heat-conducting metal material.
[0017] In some embodiments, the heat pipe is embedded in the first heat pipe groove and the second heat pipe groove.
[0018] In some embodiments, end caps are provided at both ends of the heat pipe to prevent moisture from entering the heat pipe.
[0019] In some embodiments, the power source is a solar panel or grid power.
[0020] In some embodiments, solar panels are arranged outside the bridge guardrail in a sunlight-exposed area to absorb solar energy and generate electricity.
[0021] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:
[0022] 1. The snow melting and drainage device of the present invention heats the nearby ice and snow by heating the resistance wire in the heat conducting pipe, causing the ice and snow to melt and flow out through the nearby drainage pipe, thereby reducing or even eliminating the accumulation of snow and ice on the hard shoulder of the bridge. In particular, the ice and snow accumulated in the shade are difficult to melt due to the lack of sunlight. At this time, the heat is released through the heat conducting pipe, causing the nearby ice and snow to melt and flow out.
[0023] 2. The snow melting and drainage device of the present invention heats the drain pipe through the heating device, so that the ice and snow in and around the drain pipe melt, preventing the drain pipe from being blocked and allowing the melted accumulated water to be discharged quickly.
[0024] 3. In an emergency situation on a cloudy day or at night when the light is poor, the snow melting and drainage device of the present invention uses an external power grid to keep the resistance wire heated and melt the ice and snow. After the emergency situation, it switches to solar panels to generate electricity, so that the resistance wire remains heated and the nearby ice and snow melt, allowing the device to adapt to different situations.

[0030] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.
[0031] As introduced in the background technology, the height of the hard shoulder on the bridge in the prior art is relatively low, which easily causes the problem of snow and ice accumulation on the road. In order to solve the above technical problems, the utility model proposes a snow melting and drainage device for bridges.
[0032] like Figure 1 、 Figure 2 As shown, one embodiment of the present invention describes a snow melting and drainage device for a bridge, comprising: a drainage pipe, a heat pipe groove, a heat pipe 8, a transverse cable channel 5 and a power supply 9.
[0033] In an optional embodiment, the drainage pipe includes a transverse drainage pipe 4 and a vertical drainage pipe 3. The vertical drainage pipe 3 is arranged at the shoulder or curb 1 of the bridge, and vertically or obliquely passes through the bridge deck. The transverse drainage pipe 4 is arranged at the connection between the bridge deck and the guardrail 2, and transversely or obliquely passes through the bottom of the guardrail 2. The accumulated water on the bridge pavement is discharged in time through the vertical drainage pipe 3 and the transverse drainage pipe 4.
[0034] In an optional embodiment, a first heat pipe groove 6 is provided at the junction of the shoulder or curb 1 of the bridge and the guardrail 2, that is, the junction of the road surface of the bridge shoulder 1 and the inner facade of the guardrail 2. A heat pipe 8 is provided in the first heat pipe groove 6, and a heating resistance wire is provided in the heat pipe 8. The heating resistance wire generates heat to melt the nearby ice and snow.
[0035] In an optional embodiment, a second heat conducting pipe groove 7 is arranged between the first heat conducting pipe groove 6 and the drainage pipe, the second heat conducting pipe connects the first heat conducting pipe groove 6 and the drainage pipe, and a heat conducting pipe 8 is also arranged in the second heat conducting pipe groove 7. The ice and snow on the bridge surface are melted through the heat conducting pipe 8 in the second heat conducting pipe groove 7, forming snow water that flows to the horizontal drainage pipe 4 and the vertical drainage pipe 3.
[0036] At the same time, a heat pipe 8 is also set in the horizontal drainage pipe 4 and the vertical drainage pipe 3. The heat pipe 8 runs through the horizontal drainage pipe and the vertical drainage pipe. The length of this part of the heat pipe 8 is the same as the drainage pipe. The heating resistance wire in the heat pipe 8 is heated to melt the ice in the drainage pipe, making it convenient to discharge the melted snow water on the bridge deck.
[0037] In an optional embodiment, the heat pipe 8 is buried in the first heat pipe groove 6 and the second heat pipe groove 7 .
[0038] In an optional embodiment, the heat pipe 8 is a long tubular structure, the outer shell of which is made of a heat-conducting metal material, and a heating resistance wire is provided inside the outer shell. Heat is conducted through the heat pipe to heat the nearby ice and snow.
[0039] In an optional embodiment, end covers are provided at both ends of the heat pipe, and the end covers are sealed to the heat pipe to prevent moisture from entering the heat pipe. Existing technology can be used to achieve this.
[0040] In an optional embodiment, both the horizontal drain pipe 4 and the vertical drain pipe 3 are heat-conducting metal pipes, which facilitate heat conduction to melt the ice and snow accumulated in the drain pipes.
[0041] In an optional embodiment, a transverse cable channel 5 is provided on the guardrail 2. The transverse cable channel 5 is a through hole that crosses the guardrail 2. A wire is provided in the transverse cable channel 5, and the heating device 8 is connected to the power supply 9 through the wire.
[0042] In an optional embodiment, the power source 9 is powered by a solar panel or the grid. The power source 9 can also be configured to be powered by both the solar panel and the grid. The solar panel is placed outside the bridge guardrail 2 in a sunny location. When the ambient light is sufficient, the power source 9 is configured as a solar panel to absorb solar energy to generate electricity and generate heat for the device to operate. When the ambient light is insufficient, such as on cloudy days or at night, the solar panel is disconnected and the grid is used to generate power to generate heat for the device to operate and melt ice and snow. The solar panel and grid power supplies can be switched manually or automatically using existing technology.
[0043] The power supply 9 energizes the heating resistance wire through the wire, so that the heating resistance wire works and generates heat. The connection between the heating resistance wire, the wire and the power supply 9 is the existing technology.
[0044] On sunny days, the solar panels of this device absorb solar energy and convert light energy into electrical energy to provide electricity for the heating device 8. On rainy days or when the light is poor, the power supply is switched to the grid to make the heating device 8 work. The power is transmitted to the heating resistance wire of the heating device 8 through the wires in the horizontal cable channel 5, so that the heating resistance wire of the heating device 8 is heated. The heat pipe conducts heat outward to heat and melt the nearby ice and snow and the ice and snow in the drainage pipe, ensuring that water can be discharged smoothly through the drainage pipe to the bridge limit, thereby ensuring driving safety within the bridge range.
[0045] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
