TECHNICAL FIELD
[0001] The utility model relates to the technical field of highway wind snow disaster prevention, specifically is a wind blowing snow guiding device based on vibration energy dissipation principle. BACKGROUND
[0002] Wind blowing snow is a kind of weather phenomenon of multiphase flow of dispersed snow particles running in near ground by airflow, also called wind snow flow, is a kind of more complex special fluid, has greater harmfulness.Wind blowing snow usually occurs in high latitude, high altitude and large topographic change of snow area, generally occurs after snow stops, generally appears in fine weather, wind blowing snow harm is summarized as two kinds of hazards of sight barrier and leeward snow barrier, two kinds of hazards can make highway traffic transport to suffer serious adverse effects.
[0003] In order to effectively reduce the influence of wind blowing snow on highway traffic transport, avoid traffic transport to suffer wind blowing snow disaster, our country has made progress in wind blowing snow physical research etc., adopts snow guiding facility, changes the highway structure of wind blowing snow area, snow blocking facility and snow removal method to govern wind blowing snow together;Snow guiding facility includes various types and specifications of snow guiding facility, such as wind deflector, lower wind fence etc., changes the highway structure of wind blowing snow area includes improving roadbed, repairing slope, excavating snow storage yard etc., snow blocking facility includes different specifications and structures of snow blocking fence and snow prevention forest etc.;Snow removal method includes mechanical snow removal and physical and chemical snow melting.
[0004] Most of the existing measures for preventing and treating wind blown snow in highway engineering are concentrated in setting snow blocking facilities, such as setting snow blocking wall, snow blocking fence, wind blocking board, wind blocking net and the like, however, the practical effect of these measures is greatly influenced by the terrain, wind speed and wind direction, and the prevention and treatment effect of wind blown snow disaster on the highway is mostly unsatisfactory. Due to the changeable wind speed, it is difficult to effectively block the wind blown snow, which is a complex special fluid, outside the highway through the snow blocking facilities. In actual engineering, it is usually necessary to set multiple snow blocking facilities to effectively reduce the influence of wind blown snow on highway traffic, thereby increasing the highway land range, causing waste of land resources and increasing the cost of highway wind blown snow disaster prevention and treatment. The snow removing method includes mechanical snow removing and snow melting agent snow removing. The mechanical snow removing method cannot fundamentally solve the road surface anti-skid ability, and the mechanical equipment is expensive, the equipment utilization rate is low, and the maintenance cost is high. The snow melting agent has obvious shortcomings: corrosion of road materials and pollution of environment. The method of changing the highway structure in the wind blown snow area generally has large engineering quantity, and requires more manpower and material resources, cannot flexibly and effectively respond to the changes of external conditions, and has poor snow prevention effect and low cost performance. Compared with the above, the snow guiding facility has its superiority, but also has certain limitations. The snow guiding engineering is more applicable under specific conditions, the wind is guided through the plate surface, blocking and compressing the air flow of the wind blocking board to increase the wind speed below the wind blocking board (air inlet) and the road surface, and reduce the deposition between the wind and snow and blow away the snow on the road. However, it also has many limitations, for example, the impact energy of wind blown snow on the plate surface is too strong, the inclination angle of the wind blocking board cannot be changed with the size of the actual wind force, the snow removing performance depends on the wind force, and is affected by the included angle between the wind direction and the route.

[0031] To make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.
[0033] Referring to Figures 1-7 A wind-blown snow guiding device based on the vibration energy dissipation principle, comprising a support 4, a wind deflector group, an elastic device, and a snow melting device.
[0034] A plurality of supports 4 are sequentially and spacedly arranged along the direction of the highway 1, the wind deflector group is installed between two adjacent supports, the wind deflector group comprises a plurality of wind deflectors 2 and is sequentially and spacedly arranged from top to bottom, and the lower end of the wind deflector group is inclined to the side away from the highway. The two ends of the wind deflector 2 are rotationally connected with the support 4, the elastic device is located between the two wind deflectors 4, one end of the elastic device is connected with the free end of the upper wind deflector 2, and the other end of the elastic device is connected with the rotating end of the lower wind deflector.
[0035] The snow melting device is connected with the elastic device and the wind deflector, and adopts a heat radiation mode to melt the snow accumulated on the wind deflector and the elastic device.
[0036] It should be noted that the two sides of the upper end of the wind deflector are rotationally connected with the support, the lower end of the wind deflector is inclined to the side away from the highway, the rotating end of the wind deflector is the end connected with the support, and the free end of the wind deflector is the lower end of the wind deflector.
[0037] The wind-blown snow guiding device adopts the elastic device connected with the lower end of the wind deflector, the elastic device generates high-frequency contraction under the action of wind force, and then the wind deflector generates intense small-amplitude vibration to offset part of the energy of the wind and snow impacting on the wind deflector. This can optimize the wind-blown snow guiding capacity, reduce the energy of the wind and snow impacting on the wind deflector by using the vibration energy dissipation principle, prevent the wind-blown snow guiding device from being damaged under strong and continuous impact force, avoid the accumulation of snow on the wind deflector, and improve the effect of highway wind-blown snow disaster prevention.
[0038] In some embodiments, the lower end of the support 4 is provided with a foundation 12, which is buried under the ground to improve the stability of the support, and the leeward side of the support is provided with a foot prop 3 and is arranged at an angle with the support, so as to form a triangular stable structure of the support 4, the support and the ground, thereby improving the stability of the support.
[0039] In order to further provide the stability of the support, a plurality of horizontal rods are used to connect between two adjacent supports, and the support adopts a hollow structure, which can reduce the cost of the support, and the inside of the support can also form a wire pipe of the snow melting device described below.
[0040] In some embodiments, the upper end of the air deflector is provided with a rotating shaft on both sides, and the air deflector is connected with the support 4 through the rotating shaft to realize the rotating connection of the two. It should be noted that the rotation of the air deflector is a small amplitude rotation, that is, the rotation distance required for the high frequency vibration of the air deflector. For example, the cross section of the rotating shaft is polygonal, and a corresponding polygonal hole is also arranged on the support to control the vibration angle of the air deflector by controlling the gap between the rotating shaft and the polygonal hole.
[0041] In some embodiments, the angle between the air deflector and the support is 30°, and the lower end of the upper air deflector extends downward and exceeds the upper end of the lower air deflector, forming a horizontal direction offset, that is, a louvered structure.
[0042] In some embodiments, the elastic device is a spring 5, and a plurality of springs are arranged at intervals in the horizontal direction of the air deflector. The number of springs needs to be determined according to the length of the air deflector, and the two ends of the spring are respectively fixed to the air deflector. In this embodiment, steel nails are inserted at the ends of the springs, and the two ends of the spring are connected with the air deflector through the steel nails, and the spring is located at the two ends of the air deflector.
[0043] In some embodiments, the snow melting device comprises a power generation device and a heating device.
[0044] The heating device comprises a heating cable, a reflective film and a protective layer. One end of the heating cable is connected with the power generation device, and the other end extends through the inside of the support to the air deflector. The heating cable is laid on the air deflector in an S shape. The reflective film is radiated on the air deflector and located on the top of the heating cable. The protective layer covers the top surface of the reflective film. The leeward side of the air deflector is provided with a heat preservation layer.
[0045] The reflective film is a kind of heat reflecting material, which conducts the heat generated by the heating wire to the protective layer to melt the snow on the surface of the air deflector. The protective layer plays a protective role to avoid the problem that foreign matters hit the air deflector and cause damage to it in strong wind.
[0046] The protective layer considers using extruded board, extruded board (XPS), which is a hard plate material made of polystyrene resin as raw material, formed by special process continuous extrusion foaming, and its inside is an independent closed bubble structure, which is an environmentally friendly insulation material with high compression resistance, no water absorption, moisture resistance, air tightness, light weight, corrosion resistance and long service life. It has good heat insulation performance, strong compression resistance, moisture resistance, corrosion resistance and long service life.
[0047] The material of the air deflector is high molecular polyethylene.
[0048] The heating cable is a carbon fiber heating cable, and is fixed on the air deflector by a clamp.
[0049] In some embodiments, the spring is a nickel-titanium alloy spring, and a carbon fiber heating wire is wound on the spring, and the carbon fiber heating wire is connected with the battery through a cable for melting snow and ice on the spring.
[0050] When encountering windy and snowy weather with high wind speed and long duration, the spring may be irreversibly deformed due to being compressed for too long, reducing its elasticity; and the gap between the upper and lower air deflectors is also prone to snow accumulation due to excessive snow flux, causing the gap to be blocked. This will reduce the working capacity of the overall facility. To solve the problem of reduced working performance caused by this situation, a nickel-titanium alloy spring and an air deflector with a carbon fiber heating cable insulation layer are used, and the spring is tightly wound and connected with the carbon fiber heating wire and intersects with the cable.
[0051] Nickel-titanium alloy is a shape memory alloy, and the phase transition temperature is generally 35-40℃. When it is irreversibly deformed, the temperature of the spring needs to be raised above the phase transition temperature to restore it. The initial length of the spring needs to be determined according to the size of the air deflector and the 30° angle between the air deflector and the vertical support. The carbon fiber heating wire is uniformly wound around the nickel-titanium alloy spring, fixed by a clamp, and protected by an insulating and heat-insulating rubber outer protective layer. It is connected with the cable through the support 4. The tightness of the carbon fiber heating wire winding should be considered while considering the natural length of the spring, so that when the current passes through, the heat energy generated is enough to raise the temperature of the nickel-titanium alloy spring above the phase transition temperature.
[0052] In some embodiments, the power generation device is a wind turbine 9 and a battery 6, the wind turbine 9 is installed at the top of the support, the wind turbine 9 is connected with the battery 6 through an independent cable 10, the battery is set below the ground surface, and the battery is connected with the heating cable through a total cable 11, and the independent cable 10 and the total cable are arranged in the support.
[0053] In some embodiments, the wind speed detector 8 is fixed on the wind deflector by screws and angle irons for collecting real-time wind speed, and the wind speed detector 8 is connected with the processor 7. The wind force parameters and temperature parameters monitored by the wind speed detector are transmitted to the processor in the form of electrical signals. When the wind speed and temperature reach a certain threshold, the processor issues an instruction to control the storage battery 6 to flow through the cable to the spring, the carbon fiber heating cable at the wind deflector to produce heat to make the nickel-titanium alloy spring 5 warm up and restore the original working capacity, and the snow accumulated in the gap of the wind deflector is melted to be removed.
[0054] The melting of snow is a very complex heat transfer process, which includes phase change, heat conduction, and convective heat transfer. Currently, the main snow melting methods used at home and abroad are mechanical snow removal, snow melting agent scattering, and thermodynamic snow melting method. The mechanical snow removal method cannot fundamentally solve the problem of road surface anti-skid ability, and the mechanical equipment is expensive, has low utilization rate, and high maintenance cost. The snow melting agent scattering method also has obvious shortcomings: corrosion of road materials and environmental pollution. Only the thermodynamic snow melting method has simple principle and does not cause pollution, and becomes one of the measures for road snow melting and ice melting. Therefore, the device uses carbon fiber heating cable to melt the accumulated snow on the wind deflector.
[0055] The carbon fiber heating cable 13 is a material that has been tested in the market for a long time, has high electric heating conversion efficiency and long service life, and has undergone a series of researches such as anti-permeation, enhanced tensile and shear resistance, and stable joint, etc. Compared with metal cables and aramid fiber cables, it has obvious advantages. Therefore, the device uses carbon fiber heating cable among many heating cables.
[0056] Since the wind deflector is often used on road sections where snow disasters frequently occur, it can be considered to reasonably utilize the natural wind energy to provide certain assistance for the management work. Considering that the device needs to consume a large amount of electric energy, a small wind turbine is considered to be erected on the upper part of the support to solve part of the electric energy supply problem for the operation of the device. The outer contour of the wind turbine is shown in Figure 6 The principle of the wind turbine is that the wind wheel rotates under the push of the wind force to realize the conversion of wind energy into mechanical energy. The rotating wind wheel drives the generator to rotate through the transmission system, and realizes the grid connection of the generator and the output of electric energy under the action of the control system, to complete the conversion of mechanical energy into electric energy. A general wind turbine set is composed of a wind wheel, a transmission system, a yaw system, a hydraulic system, a brake system, a generator, a control and safety system, a cabin, a tower, and a foundation. Since the device uses a small wind turbine and is fixed on the upper part of the support, the upper part of the support is taken as the foundation, and the function system is not the same as that of the traditional large wind turbine.
[0057] The above merely illustrates the technical thought of the present application and cannot limit the protection scope of the present application, and any modification made on the basis of the technical scheme according to the technical thought of the present application falls within the protection scope of the present application.
