Description

Technical Field

[0001] This utility model relates to the field of road engineering technology, specifically to a prefabricated road surface snow melting device. Background Technology

[0002] In winter, snow and ice accumulation on roads are very common. Snowfall on the road surface can easily form a thin layer of ice under the repeated compaction of vehicle loads, which leads to a sharp decrease in the road surface's anti-skid properties, reduces vehicle driving safety, and greatly increases the risk of traffic accidents. Currently, a commonly used method is to pre-bury heating cables in the road surface. By energizing the heating cables, electrical energy is converted into heat energy, raising the road surface temperature and thus achieving the effect of melting snow and removing ice.

[0003] For example, Chinese utility model patent CN222434985U proposes a prefabricated road snow melting device, comprising a prefabricated road panel in the shape of a cuboid, wherein the prefabricated road panel is divided into an upper structure and a lower structure, the upper structure being made of steel fiber reinforced concrete and the lower structure being made of ordinary concrete; multiple PVC pipes, all equidistantly arranged inside the lower structure; a heating layer located in the lower middle part of the upper structure for electrically transmitting heat; a heat insulation layer located below the heating layer to prevent heat from being transferred downwards; and a power supply system electrically connected to the heating layer, providing solar power or municipal power to the heating layer under control.

[0004] However, the current road surface pre-embedded heating cables have problems such as uneven temperature due to unreasonable wiring methods and pre-embedding locations, resulting in slow snow melting and de-icing, excessive energy consumption, and the heating layer is cast as an integral part of the concrete substrate, requiring replacement of the entire device when damaged. To address these issues, we propose a prefabricated road surface snow melting device that provides uniform heating and convenient maintenance. Utility Model Content

[0032] This application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figures 1-6 This application provides a prefabricated road snow melting device, including a modular snow melting unit 100. The modular snow melting unit 100 includes a permeable concrete layer 110, a heating layer 120, an elastic sealing layer 130, and a lower insulation substrate 140 arranged from top to bottom. The heating layer 120 has a concentric circular groove 200, and a heating wire 210 is disposed in the concentric circular groove 200. A groove is provided on one side of the modular snow melting unit 100, and a sealing connection component 300 is snapped into the groove. The sealing connection component 300 includes a U-shaped rubber sealing strip 310, and a T-shaped tenon fastener 320 is provided on one side of the U-shaped rubber sealing strip 310. The modular snow melting unit 100 is electrically connected to a humidity sensor and a heating power adjustment device.

[0034] During use, the modular snow melting unit 100 is first slidably installed into place along the I-beam keel on the bottom foundation. Then, the sealing connection component 300 is inserted into the groove between two adjacent modular snow melting units 100 to fix them in place. Then, the humidity sensor and heating power adjustment device electrically connected to the modular snow melting unit 100 are turned on to adjust the temperature of the heating wire 210 in the heating layer 120 inside the modular snow melting unit 100, so that the surface temperature of the modular snow melting unit 100 rises to melt the snow.

[0035] In some embodiments, the U-shaped rubber sealing strip 310 has a shape memory alloy skeleton embedded within it.

[0036] During use, the U-shaped rubber sealing strip 310 has a memory alloy skeleton embedded inside, which enhances the sealing of the device and prevents melted water from flowing into the device and causing damage to the heating layer 120.

[0037] In some embodiments, the concentric grooves 200 have a plurality of concentric radial structures.

[0038] During use, the concentric groove 200 has multiple concentric radial structures, which reduces the temperature difference at different locations of the device and improves the efficiency of snow melting.

[0039] In some embodiments, the elastic sealing layer 130 is a silicone rubber-silicon carbide composite material.

[0040] During use, the elastic sealing layer 130 is a silicone rubber-silicon carbide composite material, which has high temperature resistance, thermal stability, strong pressure resistance and wear resistance, improving the protection effect of the device and extending the service life of the device.

[0041] In some embodiments, the bottom of the lower insulation substrate 140 is provided with a dovetail groove 400, and the lower insulation substrate 140 is slidably connected to the I-beam keel on the bottom foundation by a slider.

[0042] During use, the bottom of the lower insulation substrate 140 is provided with a dovetail groove 400, and a slider is embedded in the dovetail groove 400.

[0043] In some embodiments, a spring 500 is provided in the dovetail groove 400, and the spring 500 is located at the top of the slider.

[0044] During use, when the modular snow melting unit 100 applies gravity downwards, the lower insulation substrate 140 inside the modular snow melting unit 100 presses the I-beam keel on the foundation through the slider embedded in the bottom dovetail groove 400. A spring 500 is provided in the dovetail groove 400 to buffer it and prevent damage to the I-beam keel.

[0045] In some embodiments, a pin hole 600 is provided on one side of the T-shaped tenon fastener 320, and a spring 610 is provided in the pin hole 600. A spherical protrusion is provided in the groove opened on one side of the modular snow melting unit 100.

[0046] During use, the T-shaped tenon fastener 320 is inserted at an angle into the groove on one side of the modular snow melting unit 100, and then the T-shaped tenon fastener 320 is rotated to make it horizontal. During the rotation, the spherical protrusion compression spring 610 in the groove on one side of the modular snow melting unit 100 is engaged with the pin hole 600, so that the adjacent modular snow melting units 100 are more securely fixed to each other.

[0047] In some embodiments, a windbreak mechanism 700 is inserted into one side of the modular snow melting unit 100.

[0048] During use, a windbreak mechanism 700 is inserted into one side of the modular snow melting unit 100. The windbreak mechanism 700 is higher than the modular snow melting unit 100, which can reduce the amount of cold air blowing on the surface of the windbreak mechanism 700 and reduce the heat dissipation of the windbreak mechanism 700 to a certain extent.
