Description

Technical Field

[0001] This invention relates to the field of traffic road defogging technology, and more specifically, to a device for enhancing visibility at intersections in severe weather. Background Technology

[0002] Among existing road fogging technologies, foggy weather significantly reduces visibility, making it a major cause of accidents. This is especially true at roundabouts, where traffic converges, driving paths are circular, and drivers need to continuously control the steering wheel, exacerbating the poor visibility conditions and increasing the risk of accidents far higher than on ordinary roads. Furthermore, the practical application of current road fogging technologies is limited. Conventional measures primarily rely on drivers passively reducing speed, increasing observation, and turning on headlights, which fails to fundamentally improve visibility in foggy conditions. The obstructed driver vision results in the inability to effectively eliminate traffic safety hazards.

[0003] Therefore, there is an urgent need for a visibility enhancement device for intersections in severe weather, which solves the problem of the inability to effectively eliminate traffic safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a visibility enhancement device for intersections in severe weather to improve the aforementioned problems. To achieve this objective, the technical solution adopted by this invention is as follows:

[0005] A visibility enhancement device for intersections in severe weather includes: a gas purification device comprising a fog-absorbing structure and a gas processing structure; the air inlet of the fog-absorbing structure extends toward the target area, and the air outlet of the fog-absorbing structure is sealed to the air inlet side of the gas processing structure; the fog-removing structure is provided with an arc-shaped jet mechanism and a gas delivery pipeline; the air inlet of the arc-shaped jet mechanism is connected to the gas delivery pipeline, and the end of the gas delivery pipeline away from the arc-shaped jet mechanism is connected to the air outlet of the gas processing structure; a thermocompression device is connected in series on the gas delivery pipeline; and the gas purified by the gas processing structure is discharged sequentially through the thermocompression device and the arc-shaped jet mechanism.

[0006] Preferably, the arc-shaped jet mechanism includes an arc-shaped pipe with jet nozzles along the target area. The arc-shaped pipe is equipped with a baffle reset support assembly inside. When the hot air from the thermo-pressing device enters the arc-shaped pipe through the air supply pipeline, it compresses the baffle reset support assembly to rotate, causing the hot air to be discharged from the jet nozzles in a V-shape to the target area.

[0007] Preferably, the baffle reset support assembly includes a rotating block and a baffle. The outer side of the rotating block is rotatably connected to the end of the baffle. A spring is fixedly connected to one side of the baffle, and a fixing block is fixedly connected to the other end of the spring. The outer side of the fixing block is fixedly connected to the pressurized air pipe of the gas supply pipeline.

[0008] Preferably, the defogging structure further includes a guardrail, the bottom of which is connected to the gas supply pipeline. The guardrail has evenly distributed side jet holes on its pole wall. The side jet holes are set at an angle to the jet direction of the arc-shaped jet mechanism. Part of the gas purified by the gas treatment structure is delivered to the arc-shaped jet mechanism, and the other part is delivered to the guardrail through the gas supply pipeline and discharged through the side jet holes.

[0009] Preferably, the hot pressing device is provided with an exhaust structure, one end of which is connected to the demisting structure, and the other end of the exhaust structure is provided with a pressurizing device and a heating device in sequence, and the other end of the heating device is connected to the gas supply pipeline.

[0010] Preferably, it also includes a fog-reducing device, which includes a lifting structure and a rotating structure. The lifting structure is vertically installed on the target area, and the top of the lifting structure is connected to the bottom of the rotating structure. An irradiation device is installed on the top of the rotating structure, and the rotating structure is rotatably connected to the irradiation device. The irradiation device unfolds in an umbrella shape as the lifting structure moves up and down.

[0011] Preferably, the rotating structure includes a rotating device and a hollow support rod. The fixed end of the rotating device is connected to the top of the lifting structure, and the free end of the rotating device is fixedly connected to the hollow support rod. The outer side of the hollow support rod is connected to the inner cavity of the irradiation device through multiple flexible hoses.

[0012] Preferably, the irradiation device includes an arc-shaped cover and a heat-guiding aluminum layer. The inner wall of the arc-shaped cover is fixedly connected to the outer wall of the heat-guiding aluminum layer. A halogen heating tube is provided on the inner wall of the heat-guiding aluminum layer. The heat from the halogen heating tube is uniformly conducted to the arc-shaped cover through the heat-guiding aluminum layer and radiated outward.

[0013] Preferably, the halogen heating tube further includes radiating infrared rays, which sequentially penetrate the heat-guiding aluminum layer and the arc-shaped cover and are emitted outward.

[0014] Preferably, it further includes a ground heating device, which includes a heating wire, and an insulation layer and a heat dissipation layer distributed vertically on the outer side of the heating wire, with the top of the insulation layer connected to the bottom of the heat dissipation layer.

[0015] The beneficial effects of this device are:

[0016] This device incorporates a fog-absorbing structure and a gas-processing structure. The air intake of the fog-absorbing structure extends towards the core area of ​​the roundabout, precisely covering the upper layer of the roundabout road surface to ensure efficient capture of saturated humid fog in this area. Then, the gas-processing structure, through multiple layers of filter membranes and a condensation separation component, thoroughly separates water droplets and particulate impurities from the air, obtaining clean air. Further, a thermostatic device heats the air to a set temperature, and an arc-shaped jet mechanism sprays it upwards onto the road, forming a continuous wall of hot air. This disrupts the suspension equilibrium of the fog droplets, causing them to quickly settle to the ground or evaporate and dissipate. This effectively improves visibility at intersections, providing clear visibility for vehicles. This invention effectively solves the problem of persistent traffic safety hazards.

Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Example 1:

[0031] like Figure 1 and Figure 2As shown, a visibility enhancement device for intersections in severe weather includes: a gas purification device 1 comprising a fog-absorbing structure 11 and a gas processing structure 12, wherein the air inlet of the fog-absorbing structure 11 extends toward the target area, and the air outlet of the fog-absorbing structure 11 is sealed to the air inlet of the gas processing structure 12; the defogging structure 2 is provided with an arc-shaped jet mechanism 21 and a gas supply pipeline 22, wherein the air inlet of the arc-shaped jet mechanism 21 is connected to the gas supply pipeline 22, and the end of the gas supply pipeline 22 away from the arc-shaped jet mechanism 21 is connected to the air outlet of the gas processing structure 12; a thermocompression device 3 is connected in series on the gas supply pipeline 22, and the gas purified by the gas processing structure 12 is discharged sequentially through the thermocompression device 3 and the arc-shaped jet mechanism 21. The fog-absorbing structure 11 employs multiple distributed fog-absorbing devices, with its air inlet extending toward the core area of ​​the intersection roundabout to ensure efficient capture of saturated wet fog on the upper layer of the roundabout road surface. The air outlet is fixedly connected to the air inlet side of the gas treatment structure 12 through a sealed pipe to ensure no leakage during fog transmission.

[0032] The specific implementation of this device is as follows: In severe weather conditions such as heavy fog, the fog-absorbing structure 11 is activated to forcibly draw in the suspended fog in the roundabout area of ​​the intersection. It is then transported through a sealed pipe to the gas treatment structure 12. After passing through multiple layers of filter membranes and condensation separation components, the water droplets and micro-particle impurities in the fog are completely separated from the air. The purified dry air enters the hot press device 3, is heated to the set temperature by the heating module, and then pressurized by the pressurization pump. It is then evenly transported through the air supply pipeline 22 to the arc-shaped jet mechanism 21 inside the guardrails on both sides. The arc-shaped jet mechanism 21 sprays a continuous hot airflow wall into an area 3-5m above the road through its inclined jet nozzles. This hot airflow wall can, on the one hand, break the suspension balance of the fog droplets, causing them to quickly settle to the ground or evaporate and dissipate. On the other hand, it can prevent the fog from the periphery from replenishing the core area of ​​the intersection. Combined with the continuous fog-absorbing treatment of the gas purification device 1, it effectively improves the visibility of the intersection, provides a clear view for vehicle driving, and significantly reduces the risk of traffic accidents caused by insufficient visibility.

[0033] like Figures 2 to 4As shown, the arc-shaped jet mechanism 21 includes an arc-shaped pipe 211 with jet nozzles along the target area. A baffle reset support assembly is installed inside the arc-shaped pipe 211. When hot air from the thermocompression device 3 enters the arc-shaped pipe 211 through the air supply pipe 22, it compresses the baffle reset support assembly, causing the hot air to be discharged from the jet nozzles in a V-shape to the target area. In this structure, when the hot air output from the thermocompression device 3 enters the arc-shaped pipe 211 through the air supply pipe 22, the airflow compresses the baffle reset support assembly, causing it to rotate and be ejected from the jet nozzles. The airflow from both sides of the arc-shaped pipes 211 forms a "V"-shaped barrier, effectively blocking fog 3-5 meters above the road, preventing it from affecting the driver's visibility.

[0034] To clarify the specific configuration of the baffle reset support assembly, the baffle reset support assembly includes a rotating block 212 and a baffle 213. The outer side of the rotating block 212 is rotatably connected to the end of the baffle 213. A spring 214 is fixedly connected to one side of the baffle 213, and a fixing block 215 is fixedly connected to the other end of the spring 214. The outer side of the fixing block 215 is fixedly connected to the pressurized air pipe of the gas supply pipeline 22. The rotating block 212 is fixedly installed on the inner side wall of the arc-shaped pipe 211. The baffle 213 is rotatably connected to the outer side of the rotating block 212 via a rotating shaft. One side of the baffle 213 is elastically connected to the fixing block 215 fixed at the pressurized air pipe interface in the gas supply pipeline 22 via a spring. Under normal conditions, the spring 214 is in a natural extension and contraction state, and the baffle 213 tightly fits against the inner wall of the arc-shaped pipe 211 to achieve sealing and protection of the jet nozzle. Furthermore, when the dry hot air (temperature controlled at 40℃-60℃, pressure at 0.3MPa-0.5MPa) heated and pressurized by the hot pressing device 3 is delivered to the arc-shaped pipe 211 through the pressurized air pipe in the air supply pipeline 22, the thrust generated by the airflow squeezes the baffle 213, causing the baffle 213 to rotate around the rotating block 212 and compress the spring 214, thereby opening the jet nozzle, and the hot air is ejected from the jet nozzle at an inclined upward angle.

[0035] To clarify the configuration of the defogging structure 2, the defogging structure 2 also includes a guardrail 23. The bottom of the guardrail 23 is connected to the air supply pipeline 22. The guardrail 23 has evenly distributed side air jet holes 24 on its pole wall. The side air jet holes 24 are set at an angle to the air jet direction of the arc-shaped air jet mechanism 21. Part of the gas purified by the gas treatment structure 12 is delivered to the arc-shaped air jet mechanism 21, and the other part is delivered to the guardrail 23 through the air supply pipeline 22 and discharged through the side air jet holes 24. The guardrail 23 is made of high-strength, corrosion-resistant material. The bottom of the guardrail 23 is sealed and connected to the air supply pipeline 22 via a branch pipe. Uniformly distributed side air jet holes 24, with a diameter of 2-4 mm and a spacing of 10-15 cm, are opened on the vertical wall. The air jet holes are horizontally outward or slightly downward at a 5°-10° angle. The side air jet holes 24 form a 60°-90° angle with the upward-sloping (30°-45°) air jet direction of the arc-shaped air jet mechanism 21. The arc-shaped pipe 211 is fitted into the internal structure of the guardrail 23. The curved surface guides rain and snow to flow naturally downwards and be discharged outside the guardrail 23, preventing rain and snow from seeping into the internal cavity and installation space. The dry air purified by the gas treatment structure 12 is heated and pressurized by the hot press device 3, and then bidirectionally transported through the diversion design of the gas pipeline 22. One part is accurately transported to the arc-shaped jet mechanism 21, and the other part enters the internal cavity of the guardrail 23 through the branch pipe at the bottom, and is then smoothly discharged through the side jet hole 24. Finally, the three-dimensional coverage of the airflow achieves efficient defogging, while ensuring stable operation of the device under complex weather conditions.

[0036] like Figure 5 As shown, the hot pressing device 3 is equipped with an exhaust structure 31. One end of the exhaust structure 31 is connected to the demisting structure 2, and the other end of the exhaust structure 31 is sequentially equipped with a pressurizing device 32 and a heating device 33. The other end of the heating device 33 is connected to the gas supply pipeline 22. The exhaust structure 31 includes a first exhaust pipe and a second exhaust pipe. Clean air treated by the gas treatment structure 12 enters the pressurizing device 32 through the first exhaust pipe and the second exhaust pipe. The pressurizing device 32 pressurizes the air accordingly. Subsequently, the gas is dried and heated by the heating device 33, and then discharged through the slow-release gas pipe and the pressurizing gas pipe in the gas supply pipeline 22.

[0037] like Figure 6 and Figure 7As shown, the system also includes a fog-reducing device 4, which comprises a lifting structure 41 and a rotating structure. The lifting structure 41 is vertically installed on the target area, and its top is connected to the bottom of the rotating structure. An irradiation device 43 is mounted on the top of the rotating structure, and the rotating structure is rotatably connected to the irradiation device 43. The irradiation device 43 unfolds in an umbrella shape as the lifting structure 41 rises and falls. In this structure, the lifting structure 41 is a vertically installed electric lifting rod. The bottom of the rotating device 421 is firmly embedded in the ground of the central island via a pre-embedded fixing seat to ensure operational stability under adverse weather conditions. The top of the lifting structure 41 is sealed and fixedly connected to the bottom of the rotating structure via a flange. The rotating structure is a geared motor with forward and reverse rotation functions. Its output shaft is rotatably connected to the central mounting seat of the irradiation device 43, and the rotation speed of the rotating structure is adjustable, enabling the irradiation device 43 to provide omnidirectional coverage.

[0038] Furthermore, the rotating structure includes a rotating device 421 and a hollow support rod 422. The fixed end of the rotating device 421 is connected to the top of the lifting structure 41, and the free end of the rotating device 421 is fixedly connected to the hollow support rod 422. The outer side of the hollow support rod 422 is connected to the inner cavity of the irradiation device 43 through multiple flexible hoses 423. In this invention, the rotating device 421 is a high-torque geared motor. The fixed end of the rotating device 421 is sealed and fixedly connected to the top of the lifting structure 41 through a flange. The free end of the rotating device 421 is coaxially fixed to the bottom of the hollow support rod 422 through a key connection, driving the hollow support rod 422 to achieve 360° rotation. The hollow support rod 422 is made of high-temperature and corrosion-resistant stainless steel. Multiple interfaces are evenly distributed circumferentially on the outer side of the hollow support rod 422, and each interface is sealed and connected to the inner cavity of the irradiation device 43 through a high-strength and high-temperature resistant flexible hose 423.

[0039] To clarify the structure of the irradiation device 43, the irradiation device 43 includes an arc-shaped cover 431 and a heat-guiding aluminum layer 432. The inner wall of the arc-shaped cover 431 is fixedly connected to the outer wall of the heat-guiding aluminum layer 432. A halogen heating tube 433 is provided on the inner wall of the heat-guiding aluminum layer 432. The heat from the halogen heating tube 433 is uniformly conducted to the arc-shaped cover 431 through the heat-guiding aluminum layer 432 and radiated outward.

[0040] Furthermore, the halogen heating tube 433 also includes infrared radiation rays, which sequentially penetrate the heat-guiding aluminum layer 432 and the arc-shaped cover 431 before being emitted outwards. The halogen heating tube 433 is a high-efficiency heating element with a power of 500-800W. When working, it can generate bright orange-red light and release highly penetrating infrared radiation. Part of the heat generated by the halogen heating tube 433 is quickly conducted to the arc-shaped cover 431 through the heat-guiding aluminum layer 432, and then radiated outwards from the arc-shaped cover 431, directly heating the surrounding air to accelerate the dissipation of fog. Another part acts directly on the fog droplets through thermal radiation, disrupting their suspension balance. At the same time, the bright orange-red light generated by the halogen heating tube 433 has strong penetrating power in foggy environments, providing a clear warning sign for the driver.

[0041] Preferably, the system further includes a ground heating device 5, which comprises a heating wire. The heating wire has an insulation layer and a heat dissipation layer arranged vertically on its outer side, with the top of the insulation layer connected to the bottom of the heat dissipation layer. The heating wire is fitted with a layered insulation sleeve and a heat dissipation sleeve, wherein the insulation sleeve is made of graphite felt material to effectively block heat radiation to deeper underground layers and reduce energy loss. The heat dissipation sleeve is made of thermally conductive silicone sheet with heat dissipation properties. The heat dissipation sleeve tightly wraps around the heating wire and makes full contact with the road surface base, efficiently conducting the heat generated by the heating wire to the road surface, avoiding heat waste, evaporating water, maintaining road surface friction, ensuring driving safety, and improving the temperature and humidity environment of the road surface, reducing the probability of fog formation.
