Technical Field

[0001] This utility model relates to the technical field of permafrost road devices, specifically an adjustable road widening structure for permafrost roadbeds in alpine meadow areas. Background Technology

[0002] Permafrost poses a significant challenge to highway construction. In winter, permafrost expands dramatically as temperatures drop, causing road surfaces to bulge. In summer, as the permafrost thaws, it shrinks rapidly, causing the road surface to subside. These subsidence changes directly affect the safety of vehicles.

However, this structure makes it inconvenient to quickly adjust the road width, and it is also inconvenient to heat the interior of the road to prevent the soil from freezing. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0028] Solar panel 23 typically consists of multiple solar cells, each made of a semiconductor material such as silicon. When sunlight shines on solar panel 23, its surface reflects, absorbs, and transmits light. Solar panel 23 usually incorporates a series of design measures to improve the efficiency of solar energy absorption and utilization, such as coating the surface with reflective materials and anti-reflective films, and employing a multi-layer structure.

[0029] Specific steps:

[0030] Light absorption: When sunlight shines on the solar panel 23, the photons are absorbed by the semiconductor material.

[0031] Charge separation: The energy of a photon causes electrons in a semiconductor material to jump to the conduction band, forming free electrons and holes.

[0032] Electric field effect: Under the influence of the electric field of the pn junction, electrons and holes move towards the N-region and P-region, respectively.

[0033] Current formation: By connecting the P region and the N region through an external circuit, electrons can flow from the N region to the P region through the external circuit, thus forming an electric current.

[0034] Energy output: Converting the generated current into useful electrical energy through a suitable load.

[0035] Solar panel 23 mainly consists of the following parts:

[0036] Photovoltaic modules: These are the core component of solar panels, also known as solar panels. They consist of many solar cells connected in series or parallel, responsible for directly converting sunlight into electrical energy. Common materials include silicon, such as monocrystalline and polycrystalline silicon, as well as newer thin-film solar cells.

[0037] Solar cells: These are the basic units of a photovoltaic module, converting sunlight into direct current through the photoelectric effect. Their efficiency, material type, and quantity determine the overall power generation capacity of the solar panel.

[0038] The controller protects the battery from overcharging and over-discharging. It receives voltage and current signals from the photovoltaic modules and adjusts the output according to the set parameters to ensure the battery operates within a safe range.

[0039] Inverter: Converts direct current (DC) to alternating current (AC), the form of electrical energy used by the home power grid. Modern solar systems are often equipped with smart inverters that provide functions such as power optimization and fault diagnosis.

[0040] Cables and connectors: Connectors link photovoltaic modules, controllers, and inverters to form a complete solar power generation system. High-quality cables ensure stable power transmission and reduce losses.

[0041] Supports and frames: Supports and frames that hold and secure the solar panels 23 are typically made of durable metal to ensure the panels are stable and secure in all weather conditions.

[0042] Please see Figure 1-2 The foundation compaction layer 12 is filled with concrete piles 11, and the upper end of the concrete piles 11 is filled with the foundation layer 13.

[0043] With this setup, by installing concrete piles 11 on the lower end face of the base course 13, stable support can be provided to reduce the impact of settlement and deformation, thereby improving the overall stability of the base course 13.

[0044] Please see Figure 1-3 A steel plate 16 is laid on the upper surface of the base course 13, and pins 18 are inserted into the interior of the base course 13. A precast concrete road 19 is laid on the upper surface of the base course 13.

[0045] With this setup, by inserting the positioning pin 17 into the steel sheet pile 15 and the pin 18 into the base layer 13, it is convenient to quickly lay and install the precast concrete road 19. The design of the detachable precast concrete road 19 allows for easy adjustment of the road width and facilitates quick disassembly and replacement, thus improving maintenance and replacement efficiency.

[0046] Please see Figure 1-3 Steel plate 111 is laid on the upper surface of the base layer 13. Steel reinforcement frame 110 is welded to the inner wall of steel plate 16. Steel reinforcement frame 110 is welded to the inner wall of steel plate 111.

[0047] With this setup, the design of the steel reinforcement frame 110 can increase the compressive strength of the precast concrete road 19, enabling it to withstand greater pressure and weight, and providing safe and reliable support for the precast concrete road 19.

[0048] Please see Figure 1 , Figure 2 and Figure 4 A cable 21 is installed inside the base layer 13, a heating tube 22 is installed inside the base layer 13, a controller is installed on the lower end face of the solar panel 23, a storage battery is installed on the lower end face of the solar panel 23, an inverter is installed on the lower end face of the solar panel 23, the inverter is connected to the cable 21, and the cable 21 is connected to the lamp head inside the lamp holder 25.

[0049] With this setup, by symmetrically arranging solar panels 23 on both sides of the base layer 13, clean and pollution-free energy can be used to heat the base layer 13 using heating pipes 22, thereby preventing frost heave and melting that could damage the interior of the base layer 13.

[0050] The working principle of this embodiment is as follows: The adjustable road widening structure of the permafrost roadbed in the alpine meadow area can provide stable support by setting concrete piles 11 on the lower end face of the base layer 13 to reduce the impact of settlement and deformation, thereby improving the overall stability of the base layer 13. By inserting the positioning pin 17 into the steel sheet pile 15 and the pin 18 into the base layer 13, it is convenient to quickly lay and install the precast concrete road 19. The design of the detachable precast concrete road 19 can easily adjust the road width and facilitate quick disassembly and replacement, thereby improving maintenance and replacement efficiency.

[0051] It is worth noting that the design of the steel reinforcement frame 110 can increase the compressive strength of the precast concrete road 19, enabling it to withstand greater pressure and weight, and providing safe and reliable support for the precast concrete road 19.

[0052] By symmetrically installing solar panels 23 on both sides of the base layer 13, clean and pollution-free energy can be used to heat the base layer 13 using heating pipes 22, thereby preventing frost heave and melting that could damage the interior of the base layer 13. The lamp cover 28 can be rotated and removed to facilitate quick and easy replacement and maintenance of the bulb 26, improving maintenance efficiency. The bulb 26 is designed to illuminate the road 14 and precast concrete road 19 at night, improving nighttime traffic safety and reducing potential safety hazards.
