Description

Technical Field

[0001] The utility model relates to the technical field of snow melting devices, in particular to an assembled road surface snow melting device. Background Art

[0002] In my country, the phenomenon of snow and ice on the road is very common in winter. Under the repeated crushing of vehicle loads, the snow on the road surface can easily form a thin layer of ice on the road surface, which causes the road surface's anti-skid properties to drop sharply, reduces vehicle driving safety, and makes traffic accidents very likely to occur.

[0003] At present, most areas in China use chemical snow-melting agents and mechanical methods to deal with snow-covered roads. However, snow-melting agents have a slow snow removal effect and cause a certain degree of pollution to the surrounding environment, while mechanical snow removal not only consumes a lot of manpower and material resources, but also further affects traffic due to the large body and low speed of snow removal vehicles.

[0004] For the above-mentioned problems, the commonly used method at present is to pre-bury heating cables in the road surface, and convert electrical energy into thermal energy by energizing the heating cables, so that the road surface temperature rises, thereby achieving the effect of melting snow and removing ice. However, due to technical limitations, the pre-buried heating cables in the road surface have problems such as slow snow melting and ice removal due to unreasonable wiring methods and pre-buried positions, excessive energy consumption, complex assembly, and insufficient energy supply methods. To solve this problem, this application proposes an assembled road snow melting device to achieve easy assembly and reasonable installation to increase snow melting efficiency. Utility Model Content

[0043] In order to improve the snow melting efficiency, the present application proposes an assembled road snow melting device, which is specifically as follows:

[0044] For reference Figure 1 The present application mainly consists of an assembled road panel 1, a PVC pipe 2 for connection arranged inside the assembled road panel 1, a heating layer 3 for generating heat, an insulating layer 4 for reducing downward heat dissipation, and a power supply system 5 for supplying power to the heating layer 3; by converting electrical energy into thermal energy, the road surface temperature is increased, thereby achieving the effect of melting snow and de-icing. Compared with traditional chemical de-icing agents and mechanical methods, the present application is not only beneficial to protecting the environment, but also reduces a large amount of manpower and material resources without affecting traffic.

[0045] For reference Figure 1 The assembled road panel 1 is a rectangular concrete structure, and the assembled road panel 1 is divided into an upper structure 11 and a lower structure 12;

[0046] In one embodiment, the specification of the prefabricated road panel 1 is set to 3.75*5*0.2m, then the height of the lower structure 12 is 13cm, and its specific preparation material is composed of ordinary concrete, and a PVC pipe 2 is arranged inside at intervals; through the arrangement of the PVC pipe 2, when multiple prefabricated road panels 1 are connected together, steel strands can be selected to pass through the PVC pipe 2 and tensioned to connect the multiple prefabricated road panels 1 into a whole, thereby achieving the effect of convenient paving over a large area.

[0047] According to the height of the lower structure 12, the height of the upper structure 11 is preferably 7 cm, and its specific preparation material is made of steel fiber concrete, wherein the heating layer 3 is arranged at the lower side of the upper structure 11, and specifically, the heating layer 3 is 4-6 cm from the top to the bottom;

[0048] For reference Figure 2, and the heating layer 3 is composed of a steel mesh 31, a carbon fiber heating cable 32 and a connector 33. The steel mesh 31 is arranged at the middle and lower side of the inner cavity of the lower structure 12. The carbon fiber heating cable 32 is U-shaped and equidistantly tied to the steel mesh 31 for powering on and heating. The connector 33 is arranged on the carbon fiber heating cable 32 for connecting to the power supply system 5 for powering on;

[0049] It should be noted that, based on the size of the above-mentioned prefabricated road panel 1, the carbon fiber heating cable 32 is U-shaped and tied to the steel mesh 31 at a certain interval. Preferably, the carbon fiber heating cable 32 is 8 cm away from the edge of the longitudinal prefabricated road panel and 3 cm away from the edge of the transverse prefabricated road panel.

[0050] Among them, when the carbon fiber heating cable 32 is powered on, in order to reduce the heat transfer to the lower side, an insulating layer 4 is set at the bottom of the heating layer 3, wherein the insulating layer 4 is preferably set to 1 cm based on the above size, so that the upper structure 11 first passes through 4 cm of steel fiber concrete as the base top, and then 2 cm downward is the position of the heating layer, and then 1 cm downward is the position of the insulating layer 4, forming a complete upper structure 11.

[0051] For reference Figure 3 The connecting piece 33 includes a connecting wire 331 and a joint 332; both ends of the carbon fiber heating cable 32 extend outward to form a connecting wire 331, and a joint 332 is provided on the two connecting wires 331 away from the carbon fiber heating cable 32; during the specific installation, after connecting multiple assembled road panels 1, two adjacent connecting wires 331 on the same side are connected through the joint 332; after the overall connection, there will be a connecting piece 33 left on each of the first assembled road panel 1 and the last assembled road panel 1 without connection work, and only these two places need to be connected to the power supply system 5;

[0052] For reference Figure 4 After the power supply system 5 contacts the connection piece 33, it provides solar power or municipal power to the heating layer 3 under control; the power supply system 5 mainly includes a transformer 51, a temperature control box 52 and a functional device 53; the output end of the transformer 51 is connected to the two connection pieces 33 that are not connected, and the input end of the transformer 51 is connected to the temperature control box 52 through a wire; the temperature control box 52 is connected to the functional device 53; the functional device 53 includes a solar power generation device 6 and a municipal power grid 7, realizing two energy supply modes. Usually, the solar power generation device converts solar energy into electrical energy and stores it in a battery. When the snow melting device needs to be powered, the battery first provides electrical energy. When the battery voltage is insufficient, it automatically switches to the municipal power grid, and the municipal power grid is used for power supply. A set of functional devices 53 can power two or more assembled road panels 1.

[0053] At the same time, the temperature control box 52 has a built-in temperature sensing chip. When the outside temperature is higher than 0°C, it stops working; when the outside temperature is lower than 0°C, it starts working. By default, the solar power generation device is used for energy supply first. When the voltage of the solar power generation device 6 is insufficient, it automatically switches to the municipal power grid for energy supply. At the same time, the power can be adjusted intelligently, first working at 1200W, and then working at 800W after two hours, so as to reduce energy consumption. The temperature control box 52 is equipped with a wireless transmission module, and the working status of the carbon fiber heating cable 32 is transmitted to an external computer for monitoring through the wireless transmission module.

[0054] For reference Figure 5 The solar power generation device 6 includes a solar panel 61, a support rod 62, a battery 63 and a base 64; the support rod 62 is installed at the bottom of the solar panel 61 to support the operation of the solar panel 61, and the base 64 is fixedly installed at the bottom of the support rod 62 to support the work, and the battery 63 is arranged on the base 64; when working, the solar panel 61 converts solar energy into electrical energy and stores it in the battery 63, and the device is first powered when it needs to work.

[0055] The municipal power grid 7 refers to a power network system that provides power transmission and distribution for a city and its surrounding areas. It is an important part of modern urban infrastructure, and this application does not go into details.

[0056] In the utility model, the working steps of the device are as follows:

[0057] 1. First, the prefabricated assembled road panel 1 is first cast with ordinary concrete for the lower structure 12, and then vibrated and compacted, and then the heat insulation material is laid, and then the steel mesh 31 with the carbon fiber heating cable 32 is placed, and then the upper structure 11 is cast with steel fiber concrete and vibrated and compacted;

[0058] 2. Secondly, the prefabricated assembled road panels 1 are spliced ​​and tensioned with reinforcement, and the connector 332 on the connecting line 331 extending outward from the carbon fiber heating cable 32 is connected;

[0059] 3. Then, connect the two unconnected connection wires 331 at both ends to the output end of the transformer 51, and then connect the input end of the transformer 51 to the temperature control box 52 with wires, and connect the temperature control box 52 to the solar power generation device 6 and the municipal power grid 7;

[0060] Finally, the temperature control box is turned on. When the outside temperature drops to 0°C, the power is turned on and energy is supplied. The carbon fiber heating cable starts to work, and the road surface starts to heat up to melt snow and remove ice. When the outside temperature is higher than 0°C, the temperature control box is powered off and stops working. The wireless transmission module in the temperature control box 52 transmits the working status of the carbon fiber heating cable 32 to an external computer in real time, which is convenient for staff to monitor and repair.

Those skilled in the art should understand that the utility model is not limited to the above embodiments.
