Description

Technical Field

[0001] The present invention relates to the field of road anti-coagulation and snow melting, and in particular to a road anti-coagulation and snow melting system and method based on same-frequency resonance. Background Art

[0002] With the continuous expansion of the national expressway network, the rapid increase in mountainous expressway mileage has brought greater convenience to travel. However, along with expressway operation, climate also poses safety risks. Expressways in subtropical humid monsoon climates experience high humidity, especially in mountainous areas, where humidity can reach over 60% even without rainfall. In winter and spring, with low temperatures and high humidity, road icing becomes a major obstacle to normal traffic. Icing is more frequent in high-altitude areas of northern China (such as Gansu and Northeast China).

[0003] Driving on icy highways will not only increase the braking distance (up to 2-3 times that of dry roads), but also increase the risk of vehicle loss of control, which can easily lead to accidents such as rear-end collisions and skidding.

[0004] Currently, de-icing technologies for roads mainly include manual de-icing, mechanical snow removal, spreading de-icing agents, adding chlorides to pavement materials, and thermal de-icing. De-icing agents are widely used due to their low cost, ease of use, and high de-icing efficiency.

[0005] However, existing technologies require manual spreading or operating machines to move on the road to remove snow, which not only consumes a lot of manpower and material resources, but also has low snow removal efficiency. Moreover, the above-mentioned snow removal operations all require road closures, which is time-consuming and labor-intensive. Summary of the Invention

[0006] One purpose of the present invention is to provide a road anti-freezing and snow-melting system and method based on same-frequency resonance, which uses ultrasonic waves to act on snow-melting net components on the road, causing the resonant balls to resonate to prevent road icing and quickly allow rainwater to penetrate.

[0007] This purpose is achieved by adopting the following technical solutions:

[0008] A road anti-freezing and snow-melting system and method based on same-frequency resonance includes ultrasonic directional horn assemblies arranged on both sides of the road, a snow-melting net assembly arranged above the road, and an asphalt layer arranged on the snow-melting net assembly; the snow-melting net assembly includes a resonance net and several resonance assemblies, the resonance assemblies are connected to the resonance net, and the resonance assembly includes a spherical shell with a resonance ball arranged inside the spherical shell.

[0009] The core component of an ultrasonic directional horn assembly is a piezoelectric transducer (made of piezoelectric ceramics or piezoelectric crystals). When a high-frequency electrical signal (typically above 20kHz) is applied, the piezoelectric material generates mechanical vibrations due to the inverse piezoelectric effect, emitting ultrasonic waves. The frequency of the ultrasonic waves emitted by the ultrasonic directional horn assembly matches the natural frequency of the resonant sphere. The ultrasonic waves emitted by the ultrasonic directional horn assembly penetrate the asphalt layer and act on the resonant sphere. When the external excitation frequency approaches the natural frequency of the resonant sphere, the resonant sphere within the asphalt layer resonates.

[0010] In addition, the viscoelasticity of asphalt will cause sound waves to attenuate, but high-frequency ultrasound (such as 20-40kHz) has relatively low attenuation in asphalt (better than low-frequency sound waves), and the energy loss can be compensated by adjusting the transmission power to ensure effective penetration depth.

[0011] Asphalt is a flexible material with inherent freeze-thaw resistance. Its high viscosity and elasticity reduce water penetration. The resonant vibrations of the resonant balls are transmitted through the resonant mesh to the asphalt surface and the water layer above it, causing micro-turbulence in the water. This turbulence disrupts the water's stillness, reducing the accumulation of water droplets on the asphalt surface and, in turn, the probability of ice nucleation. Simultaneously, the vibration energy is partially converted into heat at the asphalt-water interface, causing localized warming and accelerating heat transfer, thereby delaying ice formation.

[0012] The spherical shells are placed at the intersection of the resonance network, and several spherical shells are evenly connected to the resonance network. This arrangement forms a uniformly distributed microporous structure in the asphalt, which can not only reflect ultrasonic energy but also serve as stress dispersion points to prevent asphalt cracking caused by temperature changes.

[0013] Existing snow-melting systems typically use existing technologies to melt and remove ice after the ground freezes. However, these technologies cannot effectively prevent ice from forming before it forms. Furthermore, these technologies require road closures, preventing timely and rapid de-icing.

[0014] Compared with existing snow-melting systems, this system can reduce the accumulation of water droplets on the asphalt surface before the road freezes by transmitting the vibration of the resonant ball to the flexible asphalt surface and the water layer above it, thereby preventing the accumulated water from freezing and accelerating the outflow of water on the asphalt surface.

[0015] Therefore, compared with the existing snow melting system, this system can not only prevent water from accumulating on the asphalt surface before ice forms, thereby preventing ice from forming and achieving the anti-freezing effect, but also does not require road closures during the process, and can be operated quickly to prevent road ice from forming and achieve the anti-freezing and snow melting effect.

[0016] In addition, the system does not require operators to walk along the road to remove ice on the road. The system can achieve the de-icing effect by emitting ultrasonic waves toward the resonant balls through ultrasonic directional speaker assemblies arranged on both sides of the road to make the resonant balls resonate.

[0017] When the system is in use, the temperature monitoring component monitors the ground temperature. When the ground temperature is less than or equal to the threshold, the ultrasonic directional speaker component is adjusted to emit ultrasonic waves with the same natural frequency as the resonant ball.

[0018] Adjust the resonance of the resonant ball corresponding to the ultrasonic directional speaker assembly;

[0019] The resonant ball corresponding to the ultrasonic directional speaker assembly is adjusted to drive the other resonant balls on the resonant net to vibrate.

[0020] Among them, when an asphalt layer is provided on the road surface on both sides of the road, a snow-melting net assembly is provided in the asphalt layer on the road surface on both sides of the road, and the ultrasonic directional horn assembly emits ultrasonic waves from top to bottom toward the snow-melting net assembly in the asphalt layer on the road surface on both sides of the road, and the resonant balls on the road surface on both sides of the road resonate. Under the action of the resonance net, the resonant balls on the road surface on both sides of the road drive other resonant balls on the road to vibrate together.

[0021] When there is no asphalt on the road surface on both sides of the road, the ultrasonic directional horn assembly sends ultrasonic waves from both sides of the road toward the middle of the road. At this time, the resonant balls near the edge of the road vibrate first under the action of the ultrasonic waves. The resonant balls near the edge of the road drive the other resonant balls in the middle of the road to vibrate together under the action of the resonance network.

[0022] Furthermore, the diameter of the spherical shell is half the thickness of the asphalt layer, and the ratio of the shell's inner diameter to the resonant ball's diameter is 1:0.9-0.95. When the resonant ball vibrates within the shell, the shell acts as a "neck" and the resonant ball as a "cavity." By adjusting the dimensions of the shell and the resonant ball, resonance enhancement at specific frequencies is achieved. When the shell's inner diameter is within this ratio, the shell concentrates ultrasonic energy into the resonant ball, ensuring efficient energy transfer. The volume difference amplifies the amplitude, achieving a better vibration effect.

[0023] Furthermore, the ratio of the thickness of the spherical shell to the diameter of the resonant ball is 1:3-1:5. Preferably, the distance between two adjacent spherical shells on the resonant net is 1.8-4 cm.

[0024] If the spherical shell is too thick, the energy transfer efficiency will decrease; if it is too thin, it will be easily affected by external interference (such as deformation of the asphalt layer). Therefore, a better vibration effect can be achieved under the above settings.

[0025] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0026] The present invention discloses a road anti-freezing and snow-melting system and method based on frequency resonance. Ultrasonic waves propagate through the asphalt layer and act on corresponding resonant balls. Driven by the ultrasonic waves, the resonant balls vibrate at high frequencies, which are then transmitted to other spherical shells through a resonant network, driving all the spherical shells on the network and the resonant balls within them to vibrate. During the vibration process, as the asphalt is a flexible material, the vibrations are transmitted to the asphalt, breaking the adhesion between the ice layer and the asphalt, causing the ice to break and fall off. Simultaneously, the vibrations promote the movement of water molecules, preventing water aggregation and the formation of new ice.

[0027] This system concentrates vibration energy on the surface, avoiding damage to the base layer caused by traditional mechanical deicing and reducing the risk of reflective cracking. Furthermore, compared to traditional electric deicing methods, this system's ultrasonic technology significantly reduces energy consumption and eliminates the risk of chemical deicing agents. Furthermore, this system effectively de-ices before ice forms and can be quickly operated without road closures, making it suitable for long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0036] In the description of the present invention, it should be understood that the terms "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "high", "low", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0037] Example 1

[0038] like Figure 1 As shown, it includes ultrasonic directional horn assemblies 1 arranged on both sides of the road, a snow-melting net assembly arranged above the road, and an asphalt layer 5 arranged on the snow-melting net assembly; the snow-melting net assembly includes a resonance net 4 and a plurality of resonance assemblies, the resonance assemblies are connected to the resonance net 4, the resonance assembly includes a spherical shell 3, and a resonance ball 7 is arranged in the spherical shell 3; the ultrasonic frequency emitted by the ultrasonic directional horn assembly 1 is the same as the natural frequency of the resonance ball 7, and the ultrasonic directional horn assembly 1 causes the resonance ball 7 to resonate.

[0039] When in use, the ultrasonic directional horn assembly 1 on both sides of the road emits ultrasonic waves that penetrate the asphalt layer and act on the resonant ball 7 in the corresponding spherical shell 3. The frequency of the ultrasonic waves emitted by the ultrasonic directional horn assembly 1 is the same as the natural frequency of the resonant ball 7, thereby driving the corresponding resonant ball to resonate.

[0040] When the corresponding resonance ball resonates, under the action of the resonance net, the vibration of the resonance ball is transmitted to other resonance balls, thereby driving all the resonance balls on the resonance net to vibrate together.

[0041] like Figure 2 As shown, an asphalt layer 5 is provided on the road, and the resonance component is located in the asphalt layer 5. When in use, the resonance net, the spherical shell on the resonance net, and the resonance ball on the spherical shell in the resonance component are first laid on the road. After laying, asphalt is laid on the resonance component, and the resonance component is completely located in the asphalt layer.

[0042] When anti-freezing and snow melting is required, the ultrasonic directional horn assembly emits ultrasonic waves, which act on the resonant balls on the resonance net. The resonant balls on this part resonate and drive the resonant balls at other positions to resonate together through the resonance net.

[0043] When the resonance ball 7 in the resonance assembly vibrates, since the asphalt layer is flexible, the vibration is transmitted in the asphalt, thereby preventing water from gathering above the asphalt layer and allowing the water above the asphalt layer to flow down quickly in the asphalt layer.

[0044] The ultrasonic directional horn assembly is an existing structure. In some embodiments, the ultrasonic directional horn assembly includes an ultrasonic generator, a transducer array, a modulation module, a power amplifier, and a control unit. The ultrasonic generator produces high-frequency ultrasonic waves (typically ≥20kHz), which are beyond the human hearing range. Its short wavelength makes the sound waves highly directional, facilitating focusing and directional propagation. The transducer array consists of multiple ultrasonic emitting units, which work together to form a directional beam. The array design directly affects the accuracy of sound wave focusing and coverage. For example, an array of piezoelectric ceramic units can enhance sound power output and directivity.

[0045] The modulation module modulates audible audio signals (such as speech or music) onto an ultrasonic carrier wave. Common technologies include: Parametric array effect: This utilizes the nonlinear properties of air to demodulate ultrasonic waves into audible sound waves, achieving directional propagation. Phased array technology: This adjusts the phase difference between each transmitting unit to control the direction of sound wave interference and superposition, forming an adjustable sound beam.

[0046] The power amplifier increases the modulated signal strength, ensuring minimal attenuation of ultrasound waves over long distances. For example, the LM675T power amplifier module is used to match the power requirements of the piezoelectric ceramic array.

[0047] The control unit usually integrates a digital signal processor (DSP) or a microcontroller (such as the STM32F series) to implement audio signal processing, phase adjustment and algorithm control, and optimize sound beam focusing and direction adjustment.

[0048] In some embodiments, there are dividing barriers 2 on both sides of the road, and the ultrasonic directional speaker assembly 1 is set on the dividing barriers 2.

[0049] Example 2

[0050] Based on the above embodiment, the spherical shells 3 are arranged at the cross-intersection of the resonance net 4. The diameter of the spherical shells 3 is half the thickness of the asphalt layer 5. Several spherical shells 3 are evenly connected to the resonance net 4.

[0051] In some embodiments, the system further includes a temperature monitoring component for monitoring ground temperature.

[0052] A road anti-freezing and snow-melting method based on same-frequency resonance comprises the following steps:

[0053] The temperature monitoring component monitors the ground temperature. When the ground temperature is less than or equal to a threshold value, the ultrasonic directional speaker component 1 is adjusted to emit ultrasonic waves with the same natural frequency as the resonant ball 7.

[0054] Adjusting the resonance of the resonant ball 7 corresponding to the ultrasonic directional speaker assembly 1;

[0055] The resonant ball 7 corresponding to the ultrasonic directional speaker assembly 1 is adjusted to drive the other resonant balls 7 on the resonant net 4 to vibrate.

[0056] Specifically, the ultrasonic directional horn assemblies 1 are located on both sides of the road, and the resonance network 4 on the road is divided into four areas in the direction between the two ultrasonic directional horn assemblies 1, namely, the first area, the second area, the third area and the fourth area from left to right, wherein one ultrasonic directional horn assembly 1 on both sides of the road is located outside the first area, and the other ultrasonic directional horn assembly 1 on both sides of the road is located outside the fourth area.

[0057] The ultrasonic wave emitted by the ultrasonic directional speaker assembly 1 acts on the resonant balls on the resonant net 4 in the first area and the fourth area, and the ultrasonic wave emitted by the ultrasonic directional speaker assembly 1 is adjusted to have the same natural frequency as the resonant balls 7;

[0058] The ultrasonic waves cause the resonant balls on the first area and the fourth area to resonate, and the resonant balls on the first area and the fourth area drive the resonant balls on the second area and the third area to vibrate together through the resonant net.

[0059] In some embodiments, the temperature monitoring component uses a CG-68 permafrost sensor to support shallow to deep ground temperature monitoring, has a built-in temperature compensation module, is corrosion-resistant and can measure temperatures at different depths. The surface temperature monitoring device of the temperature monitoring component adopts an integrated sealed structure, includes a lithium battery power supply and a wireless communication module, is waterproof and anti-theft, and is suitable for long-term use in municipal transportation and the field.

[0060] In some embodiments, the threshold is 3°C. When the temperature monitoring component detects that the ground temperature is less than or equal to 3°C, the system issues a yellow warning, and the ultrasonic directional speaker component 1 emits ultrasonic waves that act on the resonance network 4 in the first and fourth areas.

[0061] In some embodiments, the threshold is 0°C. When the temperature monitoring component detects that the ground temperature is less than or equal to 0°C, the system issues an orange warning, and the ultrasonic directional speaker component 1 emits ultrasonic waves that act on the resonance network 4 in the first and fourth areas.

[0062] In some embodiments, the threshold is 0°C. When the temperature monitoring component detects that the ground temperature is less than or equal to 0°C and there is rainfall in the area within the next 5 hours, the system issues a red warning, and the ultrasonic directional speaker component 1 emits ultrasonic waves that act on the resonance network 4 in the first area and the fourth area.

[0063] When the system issues a yellow warning, the ultrasonic directional speaker assembly 1 emits ultrasonic waves at a preset time interval. In some embodiments, the preset time interval is 30 minutes, and the time for each ultrasonic wave to be emitted is 10 minutes, that is, after 10 minutes of emitting ultrasonic waves, 30 minutes later, ultrasonic waves are emitted again for 30 minutes.

[0064] When the system issues an orange warning, the ultrasonic directional speaker assembly 1 emits ultrasonic waves at a preset time interval. In some embodiments, the preset time interval is 10 minutes, and the time for each ultrasonic wave to be emitted is 30 minutes, that is, after 30 minutes of emitting ultrasonic waves, 10 minutes later, ultrasonic waves are emitted again for 30 minutes.

[0065] When the system issues a red warning, the ultrasonic directional speaker assembly 1 continues to emit ultrasonic waves.

[0066] Example 3

[0067] In some embodiments, the ratio of the thickness of the spherical shell 3 to the diameter of the resonant ball 7 is 1:3-1:5.

[0068] In some embodiments, the distance between two adjacent spherical shells 3 on the resonance network 4 is 1.8-4 cm.

[0069] Preferably, the resonant ball is a glass ball, and the natural frequency of the glass ball is between 30 Hz and 64 Hz. The ultrasonic wave emitted by the ultrasonic directional speaker assembly 1 has the same natural frequency as the glass ball.

[0070] The wavelength of ultrasound in asphalt is: λ=v / f

[0071] Where v is the speed of sound of asphalt (about 1450 m / s) and f is the ultrasonic frequency.

[0072] The spherical shell needs to be flexible to amplify the vibration of the resonant ball while avoiding excessive rigidity that causes energy loss. Therefore, in some embodiments, the ratio of the inner diameter of the spherical shell 3 to the diameter of the resonant ball 7 is 1:0.9-0.95.

[0073] The material of the spherical shell is preferably an epoxy resin-glass fiber composite material, which is an existing material and takes into account both lightweight and acoustic impedance matching.

[0074] The material of the spherical shell can also be hemp rope material, such as Figure 3 As shown, the hemp rope material is low in cost and light in weight, which is conducive to long-term use.

[0075] In some embodiments, the spherical shell is Figure 4 As shown, it includes an upper shell and a lower shell, which are detachably connected. When in use, the upper shell is connected to the resonance net.

[0076] Example 4

[0077] Based on the above embodiment, the resonant sphere is made of soda-lime glass (density 2.5 g / cm³, sound velocity 5940 m / s), with dimensions of: hollow sphere, outer diameter 5 mm, wall thickness 0.5 mm, and cavity diameter 4 mm.

[0078] The natural frequency of the resonant sphere is about 30kHz, and 1,000 spheres are evenly distributed in every cubic meter of asphalt mixture with a spacing of 4cm.

[0079] The ultrasonic directional horn assembly 1 emits ultrasonic waves with a frequency of 30kHz, a power of 500W / m², a waveform of continuous sine wave, a duty cycle of 80%, and an action time of 10 minutes per shot and a cycle interval of 30 minutes.

[0080] The resonance net is a flexible nylon net, the spherical shell is set on the resonance net, and the resonance ball is located in the spherical shell. Before the asphalt surface layer is constructed, the resonance net is laid on the base surface 6, and the ultrasonic directional horn assembly is installed on the side of the road and contacts the asphalt surface through a coupling agent (silicone oil).

[0081] Example 5

[0082] On the basis of the above embodiment, a plurality of snow-melting net assemblies are sequentially arranged in the asphalt layer from top to bottom, and the planes of the resonance nets 4 in the plurality of snow-melting net assemblies in the asphalt layer are parallel to each other. When in use, the first resonance net 4 is first laid on the base surface 6, and then the first asphalt layer is poured on the first resonance net 4. After the pouring is completed, the second resonance net 4 is laid on the first asphalt layer, and then the second asphalt layer is poured on the second resonance net 4. This cycle is repeated to obtain multiple resonance nets in the asphalt layer.

[0083] The thickness of the first asphalt layer is the same as the outer diameter of the spherical shell in the first resonance net, and the thickness of the second asphalt layer is the same as the outer diameter of the spherical shell in the second resonance net.

[0084] When the ultrasonic wave acts on the resonant balls on the corresponding resonant net, the resonant balls in the area vibrate under the action of the ultrasonic wave, which is more conducive to the anti-freezing and snow melting of the road.

[0085] In some embodiments, ultrasonic waves act on the corresponding resonant balls on the resonant net, allowing water on the road surface to quickly penetrate and reduce the aggregation of water molecules on the road surface, thereby achieving the purpose of anti-coagulation.

[0086] In some embodiments, a mobile infrared radiation device (such as a vehicle-mounted heating plate) is used to heat the ice on the road surface to further de-ice the road.
