Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of emergency management and control, in particular to a flexible blocking device. BACKGROUND

[0002] In view of the fact that once a tunnel has an emergency, the following vehicles may still drive into the tunnel, which may aggravate the severity of the accident, and in view of the need for tunnel safety protection, a blocking system for blocking the following vehicles is needed to be arranged on the traffic road.

[0003] Once an emergency occurs in the tunnel, multiple blocking systems are arranged at the tunnel entrance or before and after the tunnel entrance to implement flexible space area traffic flow blocking in the longitudinal and transverse directions to prevent the following vehicles from entering the tunnel, so as to avoid the difficulty in evacuation and rescue of the accident tunnel due to vehicle congestion and even secondary accidents.

[0004] The blocking system in the prior art uses a water curtain combined with light projection to form an image on the water curtain or water screen, thereby playing a role in blocking vehicles in three-dimensional space. However, the water curtain or water screen imaging method has low recognition and needs to be implemented in the tunnel entrance or at the tunnel entrance, which limits the use scenario. In addition, the method has low recognition and is not eye-catching, and can only be seen from a short distance, which may cause rear-end collisions due to delayed braking.

[0005] To solve the above problems, the patent CN115565318A discloses a highway traffic emergency blocking light smoke screen forming control method based on the Dinger effect. In this patent, a smoke screen is used to play a blocking role. Compared with a water curtain or water screen, the smoke screen is more eye-catching and does not cause road wetness.

[0006] The patent uses a light curtain combined with a smoke screen to enhance the blocking effect. However, the smoke ejected by the smoke generator in this patent cannot be effectively uniformly injected in a laminar flow to form a uniform smoke screen belt after leaving the device. It may form a dense and uneven smoke ring with the environmental natural wind flow direction, and the position of the smoke ring is not fixed. It may be blown away from the lane by the environmental natural wind. The stability of the smoke belt in the prior art is insufficient, which is not conducive to long-distance observation by drivers and passengers. In addition, the smoke ejected by the existing smoke generator is white smoke, which is less eye-catching under sunlight.

[0007] In addition, the light curtain in this patent is formed by a laser emitter. This method has the following disadvantages:

[0008] The laser uses a laser superposition polarizer to emit light. The thermal stability of the laser light source is poor, the brightness has thermal decay, and heat dissipation is difficult to handle, which is not suitable for hot outdoor environments. Specifically:

[0009] 1. Generally, the laser generates a laser beam, the laser generates a very concentrated laser beam, the heat dissipation pressure is very large, the light source density is very large, which causes the laser to bear a high pressure, and then when the laser bears a high pressure, a large heat dissipation area is required to disperse the heat and ensure the effectiveness of the emitted light.

[0010] 2. Electronic devices are sensitive to heat, among which the laser is most sensitive to heat, and the temperature only rises a few degrees, and the power loss is very large. This will greatly limit the use environment of the laser, such as in summer, the light attenuation is serious, and the expected effect cannot be achieved, and the strong light cannot be seen, which affects the blocking effect; although it can be cooled by blowing, but the temperature of the blown air is also high due to the high temperature in summer, and the cooling effect is not good, resulting in insufficient power output of the light and low efficiency.

[0011] 3. In addition, the laser emitted by the laser is directly emitted, and the density is too large, which exists light biological damage and potential safety factors when used. SUMMARY

[0012] The present application provides a flexible blocking device, which aims to form a uniform laminar flow smoke screen and combine with a light curtain to form a more eye-catching flexible blocking effect.

[0013] The present application is realized by the following technical scheme: a flexible blocking device, comprising a box body, a fluid inlet is formed on one side of the box body, a fluid outlet is formed on the other side of the box body, a smoke forming unit is installed in the box body, and a light curtain forming unit is also installed on one side of the box body.

[0014] The smoke forming unit comprises an air inlet cover, a fan and a smoke flow guide cover connected in sequence;

[0015] The air inlet cover is installed at the fluid inlet, a smoke storage tank is arranged in the air inlet cover, and the chemical substances in the smoke storage tank can generate smoke after being ignited;

[0016] The smoke flow guide cover is in the shape of an 8, the smoke flow guide cover comprises an upper flow guide cover and a lower flow guide cover, the upper flow guide cover and the lower flow guide cover are in communication with each other, one side of the upper flow guide cover and the lower flow guide cover away from the fan is an outflow opening in communication with each other, a flow guide grid surface is arranged on the outflow opening, the flow guide grid surface comprises a plurality of vertical flow guide grids, the flow guide grid surface is installed on the fluid outlet; flow guide columns are arranged in the upper flow guide cover and the lower flow guide cover, the flow guide columns are connected with the flow guide grid surface, one end of the flow guide column away from the fan is a closed surface, the other end of the flow guide column is a flow guide conical surface, and the closed surfaces of the two flow guide columns form smoke outflow annular bands with the inner sides of the upper flow guide cover and the lower flow guide cover, respectively.

[0017] The light curtain belt forming unit and the flow guide grid surface in the smoke forming unit are located on the same side, the light curtain belt forming unit comprises a mounting frame, a plurality of aspheric lenses and a plurality of LED light sources, the mounting frame is hollow, a plurality of aspheric lenses and a plurality of LED light sources are vertically spaced along the mounting frame, and a plurality of aspheric lenses and a plurality of LED light sources are respectively arranged on both sides of the mounting frame.

[0018] Compared with the prior art, the present application has the following advantages and beneficial effects:

[0019] In the present application, the wind from the outside enters the inlet of the fluid into the inlet of the fluid under the negative pressure of the fan, the smoke generated by the smoke tank is uniformly dispersed by the high-speed rotation of the fan fan face, and then passes through the flow space composed of the flow conical surface and the flow grid surface of the two flow guide columns in the smoke flow guide cover, and because the flow guide grid is vertically arranged, the smoke flow is guided from the turbulent state to the laminar state, forming a uniformly distributed smoke jet, thereby playing a flexible blocking role, reminding the driver and passenger of the danger in front and making emergency plans such as parking.

[0020] In the present application, the upper flow guide cover and the lower flow guide cover are in communication with each other, avoiding the discontinuity of the sprayed smoke wall, and forming a broken belt, and the smoke wall formed in the present application is continuous, and under the action of the flow guide column and the vertically arranged flow guide grid, the turbulent smoke can be changed into laminar state and sprayed, forming a uniformly distributed and regular smoke screen belt, the laminar smoke position of the spraying place is fixed, the formed smoke screen belt is more stable, and it is beneficial for the driver and passenger to observe from a distance.

[0021] In addition, the closed surfaces of the two flow guide columns in the middle form smoke ring belts with the inner sides of the upper flow guide cover and the lower flow guide cover, respectively, which can ensure sufficient wind speed, and if there is no closed surface in the middle, the end surface of the upper flow guide cover and the lower flow guide cover is a completely unobstructed smoke flow area, at this time, the pressure loss is small, but the air outlet area is large, because the pressure and the area are inversely proportional, the smoke blown out by the large air outlet area has a shorter distance, and the blocking effect is poor.

[0022] The setting of the smoke ring belt in the present application can ensure sufficient wind speed when the air is discharged, the smoke discharge distance is larger, and laminar flow can be formed.

[0023] In addition, the scheme adopts multiple high-power-density LED light sources to form multiple light sources to disperse light, and the light emitted by the light sources can be refracted and collimated into parallel light columns by the aspheric lenses. Since the LED light sources and the aspheric lenses are both provided in multiple, the multiple LED light sources and the multiple aspheric lenses can be arranged linearly, so that a continuous linear light curtain is formed by multiple-point light emission. The linear dispersion of light in the scheme is within the range of the light biological safety legal regulations, and will not cause light biological harm during use. The similar products on the market use laser polarizing sheets, and the light power density is much higher than that of the product, which has potential safety factors.

[0024] In addition, the mounting frame is used to mount the aspheric lenses and the LED light sources. Since the mounting frame is hollow, the air can flow and circulate in the entire light curtain forming unit. At the same time, the hollow structure can reduce the convective heat exchange capacity of the front of the light source, improve the stability of the light output, and form a stable and straight light curtain. When used with a smoke forming device later, the light curtain can have more effective blocking and warning effects. The similar products on the market use laser superimposed polarizing sheets to emit light, and the thermal stability of the laser light source is poor, the brightness has thermal decay, and the light output stability is poor. In the scheme, the smoke is combined with the light curtain to form a straight and uniform light smoke curtain, which can improve the prominence and thus improve the blocking effect.

[0025] Further, the middle position of the flow guide grid surface is connected with a horizontally arranged turbulent flow division plate.

[0026] Beneficial effects: In the scheme, the side of the upper flow guide cover and the lower flow guide cover away from the fan is an interconnected smoke outlet structure, so that the smoke outlets of the upper flow guide cover and the lower flow guide cover form an interconnected whole. The turbulent flow division plate is arranged at the middle position of the flow guide grid surface, so that the smoke can be continuously emitted from the middle of the smoke outlet of the smoke flow guide cover, and the upper part and the lower part of the smoke can be prevented from interfering with each other.

[0027] Under the blocking action of the turbulent flow decomposition plate, the smoke can be forced to move forward, and vortexes and turbulent flows can be avoided in the middle part of the smoke outlet, so that the smoke can only be ejected in a laminar flow to form a regular and uniform smoke curtain wall.

[0028] In addition, since the entire smoke flow guide cover in the scheme has a hollow structure, the arrangement of the turbulent flow division plate can also enhance the strength of the entire smoke flow guide cover

[0029] Further, the fan and the air inlet cover are both provided in two, and the two fans and the two air inlet covers are arranged opposite to the upper flow guide cover and the lower flow guide cover, respectively.

[0030] Beneficial effects: two fans and two air inlet covers in the scheme are respectively opposite to the upper and lower guide covers, so that the generated smoke curtain wall laminar flow is more uniform, and the smoke curtain wall effect is better.

[0031] Further, the smoke storage tanks are provided in plurality, and the plurality of smoke storage tanks are uniformly distributed along the circumference of the air inlet cover, and the smoke storage tanks are close to the inscribed surface of the air inlet cover.

[0032] Beneficial effects: the plurality of smoke storage tanks in the scheme can be ignited according to actual needs, and whether the smoke storage tank needs to be ignited again can be judged according to whether the on-site interception is successful.

[0033] In addition, compared with the plurality of smoke storage tanks being arranged at the middle position of the air inlet cover, the plurality of smoke storage tanks in the scheme are arranged close to the inscribed surface of the air inlet cover, so that the wind resistance and pressure loss can be reduced, the wind speed can be prevented from decreasing too fast, the smoke can be made more uniform, the smoke storage tanks are arranged at the inscribed surface of the air inlet cover, so that the smoke is discharged at the outermost side, and during the rotation of the fan surface of the fan, the wind force rotates to the center, so that the smoke can be uniform on the entire flow surface, the smoke discharge is more uniform, and the effect is better.

[0034] Further, one side of the box is provided with a mounting groove, and the light curtain belt forming unit is mounted in the mounting groove; the mounting bracket comprises a mounting plate for mounting the aspheric lens and a heat dissipation base for mounting the LED light source, and an adjusting seat is connected between the heat dissipation base and the mounting plate, and the adjusting seat is provided with an adjusting piece capable of adjusting the distance between the mounting plate and the heat dissipation base.

[0035] Beneficial effects: the mounting bracket formed by the mounting plate, the heat dissipation base and the adjusting seat is hollow, which is simple in structure and can make the air in it form convection and heat dissipation effect, so as to ensure stable light emission and reduce light attenuation degree.

[0036] In addition, in actual use, if the aspheric lens and the LED light source are inclined to each other and not opposite to each other, the emitted light source will be staggered and disordered, and the light curtain wall effect will be poor; in the scheme, the distance between the mounting plate and the heat dissipation base is adjusted by the adjusting piece, so as to adjust the position between the aspheric lens and the LED light source, so that the aspheric lens and the LED light source are in parallel, so that each beam of light emitted is parallel, forming a parallel light curtain wall, which is convenient for cooperation with the parallel smoke wall in the later period, so as to improve the presentation effect of flexible blocking.

[0037] Further, a protective door is slidably connected in the mounting groove, and sliding the protective door can open or close the mounting groove, and the box is provided with a driving piece for driving the protective door to open and close.

[0038] Beneficial effects: in the scheme, when the light curtain belt forming unit is started, the driving part opens the protective door, and then the light curtain belt forming unit is opened; when the light curtain belt forming unit function is closed, the driving part closes the protective door. In the closed state of the protective door, the non-spherical lens surface can be kept clean for a long time in any outdoor environment, and the light band effect during use can be stably ensured.

[0039] Further, a wind speed monitor is mounted on the top of the box.

[0040] Beneficial effects: the wind speed monitor in the scheme can measure the wind grade in the environment on site, provide a decision for the wind pressure intensity blown by the fan, and facilitate directional control in the later period.

[0041] Further, a display screen, a warning light and a directional broadcast are installed on one side of the box facing the direction of the vehicle, and the warning light and the directional broadcast are located on the upper part of the box and above the display screen.

[0042] Beneficial effects: in the scheme, the display screen performs dynamic video warning or high-light text warning, the warning light increases the warning effect, and the directional broadcast reports the accident content, so that the scheme can accurately provide emergency safety induction for the driver and passenger through multi-dimensional stimulating factors.

[0043] Further, a road direction video monitoring unit and a roadside video monitoring unit are further installed on the box, the road direction video monitoring unit is located on the same side as the warning light, and the roadside video monitoring unit is located on the same side as the flow guide grid surface.

[0044] Beneficial effects: in the scheme, video data analysis can be carried out based on the road side and the road direction, real-time update of early warning voice information and video picture text information can be facilitated, and the opening and closing states of the smoke forming unit and the light curtain belt forming unit can be determined in real time; similar devices on the market have no real-time update strategy and no active correction function, cannot update the strategy according to the real-time blocking effect of the road section, and cannot reasonably guide the driver and passenger to have orderly safety guidance to avoid secondary accident damage.

[0045] Further, a closed fence is connected to the bottom of the box, a wire inlet hole is formed in the bottom of the box, and the wire inlet hole is located inside the closed fence.

[0046] Beneficial effects: the closed fence in the scheme can make the whole structure more beautiful and compact, the closed fence has the functions of blocking water and preventing animals from straying in, and the wire inlet hole is convenient for accessing communication cables or cables into the equipment.

[0078] Example 1, such as Figures 1-2 As shown, this embodiment 1 provides a flexible barrier device, including a box 1, a fluid inlet on one side of the box 1, a fluid outlet on the other side of the box 1, a smoke forming unit 2 installed inside the box, and a light curtain strip forming unit 3 installed on one side of the box.

[0079] The two fluid inlets are arranged facing each other vertically. In this embodiment, two rainproof guide hoods 107 are connected to the outside of the housing 1, and the two fluid inlets are located inside the rainproof guide hoods 107 respectively.

[0080] Both rainproof deflectors 107 are integrally formed with the housing 1 or connected by screws or welding. The rainproof deflector 107 is cylindrical in shape, and a structure with a wider top and narrower bottom is formed by oblique cutting on the cylindrical cover.

[0081] The smoke forming unit 2 is installed inside the housing 1, combined with Figure 3 As shown, the smoke forming unit 2 includes an air inlet hood 201, a fan 202, and a smoke guide hood 203 connected in sequence;

[0084] The smoke deflector 203 is in the shape of an 8. The smoke deflector 203 includes an upper deflector 2034 and a lower deflector 2035. The upper deflector 2034 and the lower deflector 2035 are hollow inside and are in communication with each other.

The two fans 202 and the two air inlet covers 201 are arranged opposite to the upper deflector 2034 and the lower deflector 2035 respectively. The outer shell of the fan 202 is connected to the air inlet cover 201 and the smoke deflector 203 by screws at both ends. The end of the air inlet cover 201 away from the fan 202 is connected to the box body 1 by screws.

[0085] In this embodiment, the upper deflector 2034 and the lower deflector 2035 are connected by a circular arc and form an integral whole. A plurality of horizontal gratings are arranged at the middle positions of the upper deflector 2034 and the lower deflector 2035. The horizontal gratings not only connect the upper deflector 2034 and the lower deflector 2035, but also make the spaces of the upper deflector 2034 and the lower deflector 2035 communicate with each other.

[0086] The side of the upper deflector 2034 and the lower deflector 2035 away from the fan 202 is an 8-shaped smoke outlet. The side of the smoke deflector 203 away from the fan 202 is a complete 8-shaped through hole. A deflector grating 2031 is arranged on the smoke outlet. The deflector grating 2031 includes a plurality of vertical deflector gratings 2031 arranged at intervals. The deflector grating 2031 is installed on the fluid outlet. The shape of the fluid outlet is matched with the shape of the deflector grating 2031.

[0087] As shown in Figure 6 and Figure 7As shown, the upper and lower fairing 2034 and 2035 are provided with a guide column 2032, two guide column 2032 and guide grid 2031 face connection, in this embodiment, the guide column 2032 and guide grid 2031 face of the guide grid 2031 is welded and fixed, two guide column 2032 and upper and lower fairing 2034 and 2035 coaxial arrangement, the guide column 2032 away from the end of the fan 202 is closed face 20321, the other end of the guide column 2032 is guide conical surface 20322, the closed face 20321 of the two guide column 2032 and the inner side of the upper and lower fairing 2034 and 2035 form a smoke ring, the vertex of the guide conical surface 20322 and the fan surface 2021 of the fan 202 have a spacing.

[0088] In combination Figure 4 As shown, the middle position of the guide grid 2031 face is connected with a horizontally arranged turbulent flow dividing plate 2033, the upper and lower parts of the guide grid 2031 face are respectively connected with horizontally arranged upper and lower dividing plates 2036 and 2037, the turbulent flow dividing plate 2033, the upper and lower dividing plates 2036 and 2037 are transversely inserted between the plurality of vertically arranged guide grids 2031, and the width of the turbulent flow dividing plate 2033, the upper and lower dividing plates 2036 and 2037 is less than the width of the guide grid 2031, in this embodiment, one end of the turbulent flow dividing plate 2033, the upper and lower dividing plates 2036 and 2037 is flush with the outer side of the guide grid 2031 face, in this embodiment, the width of the turbulent flow dividing plate 2033, the upper and lower dividing plates 2036 and 2037 is about 1 / 4 of the width of the guide grid 2031. In this embodiment, the width of the guide grid 2031 is less than the width of the smoke guide fairing 203. Specifically:

[0089] In combination Figure 6 、 Figure 7 、 Figure 8 And Figure 9 As shown, the center distance L1 of the two guide columns 2032 is 600-700mm, the angle r of the guide conical surface 20322 is 110-130°, the height h1 of the guide conical surface 20322 is 80-90mm, the distance h2 between the vertex of the guide conical surface 20322 and the fan surface 2021 of the fan 202 is 35-45mm, the width of the smoke ring is 180-220mm, the spacing j between the adjacent two guide grids 2031 is 15-20mm, the width W1 of the guide grid 2031 is 115-130mm, and the width W2 of the turbulent flow dividing plate 2033, the upper and lower dividing plates 2036 and 2037 is 40-60mm;

[0090] The center distance L1 of the two guide columns 2032 is 650 mm, the width L2 of the guide grid surface is 1150 mm, the angle r of the guide conical surface 20322 is 120°, the height h1 of the guide conical surface 20322 is 87 mm, the distance h2 between the vertex of the guide conical surface 20322 and the fan surface 2021 of the fan 202 is 38 mm, the width of the smoke discharge ring is 200 mm (i.e. the inner diameter of the smoke discharge ring in this embodiment is 300 mm, the outer diameter is 500 mm, and the diameter of the closed surface of the guide column is 300 mm), the spacing j between the two adjacent guide grids 2031 is 17 mm, the width W1 of the guide grid 2031 is 122 mm, and the width W2 of the turbulence demarcation plate 2033, the upper demarcation plate 2036 and the lower demarcation plate 2037 is 50 mm.

[0091] If the guide grid 2031 in this embodiment is set too wide, the wind speed passing through will decrease rapidly, and the pressure loss will be smaller. However, in this case, the wind speed is small, and the laminar flow cannot be formed or the laminar flow effect is poor. The width of the guide grid 2031 in this application is designed to have small pressure loss and small effect on wind speed, so that the laminar flow can be effectively formed. In addition, the guide angle of the guide conical surface 20322 in this embodiment is large, and the height is short, so that the overall thickness can be compressed, and the entire box can be miniaturized. In this way, the gap between the guide conical surface 20322 and the smoke deflector 203 is large, so that the smoke passing through receives less blocking effect from the inner wall of the smoke deflector 203, thereby reducing the pressure loss of the smoke flowing through, and the laminar flow of the discharged smoke is more uniform.

[0092] In combination with Figure 10 As shown in the figure, the fluid inlet guard net 108 is installed in the two fluid inlets, and the fluid inlet guard net 108 is fixed on the box 1 by screws. The smoke storage tank 204 is connected with the fluid inlet guard net 108 by screws.

[0093] In this embodiment, eight smoke storage tanks 204 are provided, which are uniformly distributed along the circumference of the air inlet cover 201, and the smoke storage tank 204 is close to the inscribed surface of the air inlet cover 201.

[0095] The similar products on the market adopt the scheme of spraying oil high-pressure injection to form smoke, such a scheme has the disadvantages of long pre-injection starting period, generally 5-15s, and the smoke is not easy to be observed by the drivers 100 meters away in the sunlight irradiation environment; the system adopts saturated fatty acid-lipid superimposed organic pigment combustion chemical change to form colored smoke, which can be clearly observed by the drivers 100 meters away, the smoke emission time is short and can be controlled within 3s, and the effectiveness of the emergency starting scheme is effectively ensured.

[0096] In the embodiment, a mounting groove is formed on one side of the box body 1, and the light curtain forming unit 3 is mounted in the mounting groove, and in the embodiment, the mounting groove and the fluid outlet on the box body 1 are located on the same side, so that the light curtain forming unit 3 and the flow guide grid in the smoke forming unit 2 are located on the same side, so that the formed light curtain and the smoke emitted by the smoke forming unit are located on the same side, thereby forming a flexible blocking effect of light smoke curtain combination.

[0097] Specifically, as shown in Figure 12 、 Figure 13 、 Figure 14 and Figure 15 , the light curtain forming unit 3 in the embodiment includes a mounting frame, a plurality of aspheric lenses 301 and a plurality of LED light sources, the mounting frame is hollow, the plurality of aspheric lenses 301 and the plurality of LED light sources are vertically spaced along the mounting frame, and the plurality of aspheric lenses 301 and the plurality of LED light sources are respectively arranged opposite to the two sides of the mounting frame.

[0098] The number of LED light sources and aspherical lenses 301 is the same, and the LED light sources and aspherical lenses 301 are arranged sequentially and directly opposite each other. The LED light sources and aspherical lenses 301 are arranged linearly, that is, in a vertical straight line. The light emitted by each LED light source is refracted by the aspherical lenses 301 and then emitted in a straight line.

[0099] Combination Figure 14 and Figure 15 As shown, the mounting bracket includes a mounting plate 30 for mounting the aspherical lens 301 and a heat sink 302 for mounting the LED light source. An adjustment seat 304 connects the heat sink 302 and the mounting plate 30, thus making the entire mounting bracket hollow. In this embodiment, the LED light source includes an LED lamp 303 and a high thermal conductivity aluminum substrate 3033. The leads of the LED lamp 303 are soldered onto the high thermal conductivity aluminum substrate 3033, and the high thermal conductivity aluminum substrate 3033 is connected to the heat sink 302.

[0100] Mounting plate 30 includes lens fixing plate 306 and lens pressing plate 305. Both lens fixing plate 306 and lens pressing plate 305 have through holes for mounting aspherical lens 301. The mirror surface of aspherical lens 301 passes through the through hole, and one end of aspherical lens 301 is located between lens fixing plate 306 and lens pressing plate 305. Lens fixing plate 306 and lens pressing plate 305 are connected to each other to fix aspherical lens 301. In this embodiment, lens fixing plate 306 and lens pressing plate 305 are connected and fixed by rivets or screws, thereby installing and fixing aspherical lens 301.

[0101] In this embodiment, four mounting brackets are provided, arranged vertically along the mounting groove. In each bracket, the mounting plate 30 and the heat dissipation base 302 are connected by adjusting seats 304. Each mounting bracket has two sets of adjusting seats 304, located at the upper and lower parts of the bracket respectively, with two adjusting seats in each set, resulting in four adjusting seats 304 in each bracket, arranged in a rectangular array. Each mounting bracket in this embodiment also has four aspherical lenses 301 and four LED light sources.

[0102] like Figure 15 As shown, the mounting plates 30 in the four mounting brackets overlap and are spliced ​​together, thus creating a seamless connection between the mounting plates 30. However, the heat dissipation bases 302 in the four mounting brackets have gaps between them, which expands the space and path for heat dissipation. Combined with... Figure 2As shown, the mounting groove is provided with a rib plate 318, and a receiving cavity is formed between the mounting groove and the rib plate 318. The mounting plate 30 is fixedly connected with the rib plate 318 in the mounting groove through screws. The aspheric lens 301 on the mounting plate 30 protrudes outward of the rib plate 318, so as to avoid the rib plate 318 from shielding the aspheric lens 301 and affecting the light emitting effect. The heat dissipation base 302 and the adjusting seat 304 are located in the receiving cavity formed between the rib plate 318 and the mounting groove.

[0103] In combination Figure 12 and Figure 14 As shown, the width d formed by the plurality of aspheric lenses 301 in the embodiment is 1440mm. The light emitting diameter D of the aspheric lens 301 is 55-65mm. The distance d2 between the tangent lines of the closest sides of the adjacent two aspheric lenses 301 is 28-38mm. The center distance d1 between the adjacent two aspheric lenses 301 is 88-98mm. The distance d3 between the aspheric lens 301 and the LED lamp 303 is 28-40mm.

[0104] As preferred, the optimal size data in the embodiment are as follows: the light emitting diameter D of the aspheric lens 301 is 60mm. The distance d2 between the tangent lines of the closest sides of the adjacent two aspheric lenses 301 is 32mm. The center distance d1 between the adjacent two aspheric lenses 301 is 92mm. The distance d3 between the aspheric lens 301 and the LED lamp 303 is 34mm.

[0105] In the embodiment, a sealing strip is attached between the light curtain strip forming unit 3 and the mounting groove for sealing treatment, thereby achieving waterproof effect.

[0106] The specific implementation process is as follows: in the embodiment, the smoke flow formed by the smoke flow guide cover 203 is uniformly distributed, with a width greater than 1150mm and a length controllable at more than 5m according to the natural wind direction and wind speed of the environment. When in use, the device is symmetrically installed on both sides of the road. The smoke flow guide covers 203 of the devices on both sides of the road are arranged opposite to each other, so that the formed smoke curtain wall can stably cover highways of various widths. In addition, the light emitting width of the light curtain strip forming unit 3 in the device is 1440mm, which can form a uniformly 1440mm wide optimal visible concentration red light smoke strip in cooperation with the smoke curtain wall, thereby improving the observation distance of the driver and passenger.

[0107] In combination Figure 7As shown, the external fluid is introduced into the air inlet hood 201 from the rainproof flow guide cover 107 under the action of the fan 202, the smoke bomb 2043 is ignited after the electronic ignition, the smoke is uniformly dispersed by the high-speed rotation of the fan blade 2021, and the smoke fluid is guided from the turbulent flow state to the laminar flow state by the flow space composed of the flow guide conical surface 20322, the turbulent flow division plate 2033 and the flow guide grid 2031 surface, and is sprayed out to form a uniformly distributed smoke spray flow, and the flow path is shown by the arrow.

[0108] In combination Figure 21 As shown, it is a fluid analysis diagram of laminar smoke outflow using the 8-shaped smoke flow guide cover 203 in the embodiment; the middle of the flow guide grid 2031 surface is connected, and the structure at the middle position is not closed, so that the smoke out of the smoke flow guide cover 203 is continuous, and the smoke screen formed by the smoke out of the smoke flow guide cover 203 is not discontinuous. In actual use, the lamp strip can also be matched to improve the blocking warning effect. The light needs smoke as a medium to be seen, so the middle position of the flow guide grid 2031 surface is connected, so that the smoke out is continuous, and when the light is matched, a continuous and complete smoke band is formed, avoiding the incoherent situation. In combination Figure 22 As shown, it is a fluid analysis diagram of laminar smoke outflow when the middle of the smoke flow guide cover 203 is not connected. It can be seen that when the middle of the smoke flow guide cover 203 is not connected, the laminar outflow of smoke is not uniform, and the smoke screen formed by the smoke is discontinuous and broken in the middle.

[0109] In addition, in the embodiment, the smoke flow guide cover is in the shape of 8, so that the upper flow guide cover and the lower flow guide cover are arranged in an upper-lower overlapping manner, and the upper flow guide cover and the lower flow guide cover are connected to each other, avoiding the discontinuity of the smoke screen in the middle and the formation of a broken band. The smoke screen formed in the present scheme is continuous, and under the action of the flow guide column and the vertically arranged flow guide grid, the smoke in the turbulent flow state can be changed into the laminar flow state and sprayed out, forming a uniformly distributed and regular smoke screen band. The laminar smoke position of the spray is fixed, the formed smoke screen band is more stable, and it is beneficial for the driver and passenger to observe from a long distance.

[0110] In the present scheme, the smoke flow guide cover is in the shape of 8, and cannot be rectangular. The closed surfaces of the two flow guide columns in the middle form smoke outflow annular bands with the inner sides of the upper flow guide cover and the lower flow guide cover, which can ensure sufficient wind speed. If there is no closed surface in the middle, and the end surfaces of the upper flow guide cover and the lower flow guide cover are completely open smoke flow areas, the pressure loss is small at this time, but the air outlet area is large. Since the pressure and the area are inversely proportional, the smoke blown out by the large air outlet area is closer, and the blocking effect is poorer

[0111] In the smoke deflector 203 of the 8-shaped structure, the closed surface 20321 on the deflector column 2032 prevents the smoke from directly emitting from the circumferential end surface of the entire smoke deflector 203, and the smoke ring band cannot be too narrow, otherwise, the wind vortex of the emitted smoke will be caused, and it is difficult to form the laminar smoke curtain, and the size of the smoke ring band in the embodiment can ensure that the wind speed is sufficient when the wind is formed, and the uniform laminar smoke curtain is formed.

[0112] The light curtain belt forming unit in the embodiment includes a heat dissipation base 302, a high-power density LED lamp 303, a high-thermal-conductivity aluminum substrate 3033, an adjusting seat 304, a lens pressing plate 305, a lens fixing plate 306, and an aspheric lens 301. The light emitted by the LED light source is collimated into parallel light columns after passing through the aspheric lens 301, and a plurality of light sources and a plurality of aspheric lenses 301 are linearly arranged to form a light curtain belt with a width of 1440 mm.

[0113] In the embodiment, the high-power density LED lamp 303 is closely connected with the high-thermal-conductivity aluminum substrate 3033 and the heat dissipation base 302 to form an efficient heat conduction path and perform convection and radiation heat dissipation through the heat dissipation base 302. Meanwhile, the lens fixing plate 306, the lens pressing plate 305, and the adjusting seat 304 form a hollow structure with the heat dissipation base 302, which can reduce the convective heat exchange capacity of the front of the light source and improve the stability of the light output. In the scheme, the mounting frame is hollow, the temperature rises by 5℃ or less during normal operation, and the product has good operation stability.

[0114] Embodiment 2, the difference between this embodiment and embodiment 1 is that Figure 16 and Figure 17 As shown in the figure, the adjusting seat 304 in the embodiment is provided with an adjusting piece capable of adjusting the distance between the mounting plate 30 and the heat dissipation base 302. Specifically, the adjusting piece in the embodiment includes an adjusting screw and a locking screw, and the adjusting screw and the locking screw are sequentially provided with an adjusting threaded hole 307, a positioning hole 308, and a locking threaded hole 309 on the heat dissipation base 302 corresponding to each adjusting seat 304 and on the adjusting seat 304, and the mounting plate 30 is also provided with a positioning hole 308 opposite to the positioning hole 308 on the heat dissipation base 302.

[0115] The position of the adjusting seat 304 is positioned by inserting a positioning screw into the positioning hole 308 of the mounting plate 30 and the positioning hole 308 of the heat dissipation base 302. One end of the adjusting screw passes through the adjusting threaded hole 307 on the heat dissipation base 302 and the adjusting seat 304 in sequence and abuts against the mounting plate 30.

[0116] In each group of mounting racks, the height is adjusted by rotating the adjusting screw to press against the mounting plate 30 to a threaded depth, four heat dissipation bases 302 form four-point adjustment (four points determine a plane), so as to ensure that the plane formed by the lens pressing plate 305 and the lens fixing plate 306 is parallel to the heat dissipation base 302 on which the LED light source is mounted, thereby ensuring the parallelism between the LED light source and the aspheric lens 301; after adjustment, the locking screw hole 309 and the matching locking screw are used for fixing to avoid loosening and affecting the dimensional stability.

[0117] In this embodiment, the hole diameters of the adjusting screw hole 307 and the locking screw hole 309 are different, so that during use, the threaded holes used for adjusting the distance between the mounting plate 30 and the heat dissipation base 302 can be accurately distinguished, so that the adjustment direction and position of the four adjusting seats 304 in each group of mounting racks remain consistent, which can ensure the parallelism between the aspheric lens 301 and the LED light source.

[0118] In combination with Figure 12 , Figure 13 The difference between this embodiment and embodiment 1 is that the mounting slot is slidably connected with a protective door 310, the sliding protective door 310 can open or close the mounting slot, and the box body 1 is provided with a driving member 313 for driving the protective door 310 to open and close.

[0119] In this embodiment, the driving member 313 is a hydraulic cylinder or an electric cylinder, the driving member 313 is installed on the rib plate 318, and the output end of the driving member 313 penetrates one side of the protective door 310, the output end of the driving member 313 is provided with a pin hole, and the output end of the driving member 313 is fixedly connected with the protective door 310 by penetrating a pin into the pin hole. The mounting mode of the output end of the driving member 313 and the protective door 310 is not limited to the above mode, and the fixed mode and structure can be selected according to actual needs.

[0120] As shown in Figure 13 , the top wall of the mounting slot is connected with a sliding rail 311, the top of the protective door 310 is connected with a sliding block 312 through a screw, the sliding block 312 and the sliding rail 311 are in sliding cooperation, the bottom wall of the mounting slot is connected with a guide block 314, and the bottom of the protective door 310 is in sliding cooperation with the guide block 314, and in combination with Figure 12 and Figure 18As shown, a guide groove 316 is provided on one side of the guide block 314 along the sliding direction of the protective door 310. A limit rod 315 is connected to the lower part of the protective door 310. One end of the limit rod 315 is inserted into the guide groove 316 and can slide along the guide groove 316. In this embodiment, the limit rod 315 is a screw. One end of the screw passes through the protective door 310 and is inserted into the guide groove 316. The limit rod 315 can play a positioning role for the opening and closing state of the protective door 310. When the limit rod 315 abuts against the left side of the guide groove 316, the protective door 310 is closed in place. When the limit rod 315 abuts against the right side of the guide groove 316, the protective door 310 is opened in place.

[0121] like Figure 18 As shown, in this embodiment, a plurality of spaced guide steel balls 317 are installed on the top of the guide block 314 along the sliding direction of the protective door 310. In this embodiment, a plurality of recessed holes for installing guide steel balls 317 are opened on the top of the guide block 314, and the guide steel balls 317 are embedded in the recessed holes. A groove is opened on the bottom of the protective door 310, and the groove at the bottom of the protective door 310 covers the outside of the guide block 314 and slides with the guide block 314. The limiting rod 315 is fixed on one side of the groove of the protective door 310.

[0122] In this embodiment, the protective door 310 structure and the light curtain strip forming unit 3 are controlled by the control circuit inside the equipment. When the function is activated, the control drive unit 313 first pushes the protective door 310 to open, and then the light curtain strip forming unit 3 opens. When the function is deactivated, the light curtain strip forming unit 3 closes, and then the drive unit 313 pulls the protective door 310 to close.

[0123] The protective door 310 is made of a non-transparent material. In this embodiment, the protective door 310 can be made of stainless steel or other metal materials. This allows the protective door 310 to protect the internal structure from dust while preventing external sunlight from affecting the aspherical lens 301 when it is not in use. If the protective door 310 were made transparent, external sunlight would pass through the protective door 310 and form small light spots inside the mounting groove, which could easily burn out the internal components. Furthermore, transparent protective doors are usually made of glass or plastic. Glass protective doors are difficult to mold, and both plastic and glass protective doors have poor weather resistance.

[0124] In this embodiment, the protective door 310 provides a high level of protection when closed, ensuring that the surface of the aspherical lens 301 remains clean and stable in any outdoor environment, thus guaranteeing the projection light strip effect during use.

[0125] Example 4, the difference between this example and Example 1 is as follows: Figure 1As shown, a wind speed monitor 101 is installed on the top of the cabinet 1 in this embodiment, and the environmental wind speed and direction are monitored by the wind speed monitor 101. In this embodiment, the system algorithm model can be used to determine the shaped fluid state, and the uniform distribution type smoke curtain wall in the laminar flow state can be effectively formed in the environment with different wind speed and direction, so as to implement consistency and safety in different weather environments.

[0126] The smoke in the environment with different flow wind speed can be obtained by superimposing two standard models, one is an atmospheric diffusion model, and the other is a Gaussian plume model.

[0127] As shown, for the smoke flow state satisfying the following four points, the Gaussian plume model can be simplified to obtain: Figure 23

[0128] 1. The average flow field of the wind is stable, the wind speed is uniform, and the wind direction is straight.

[0129] 2. The y and z axis directions conform to the normal distribution.

[0130] 3. The mass conservation of the smoke in the transportation and diffusion.

[0131] 4. The smoke output source is uniform and continuous.

[0132] The general form of the Gaussian plume model is as follows,

[0133] .

[0134] Wherein, the X axis direction of the coordinate system is the wind direction, c is the concentration of the point at any coordinate (x, y, z) calculated by the model, Q is the gas emission rate, U is the wind speed, y is the y coordinate of the point, that is, the crosswind distance, and z is the z coordinate of the point.

[0135] σy and σz are atmospheric diffusion parameters in the y and z directions respectively. The emission rate Q and the wind speed U are directly related to the concentration C, and the rest of the formula defines the shape of the plume; for a three-dimensional plume, the z-direction cumulative distribution is observed from the front, and this distribution is the integral of the three-dimensional plume in the y direction, which can be described by the following formula to describe the shape of the plume.

[0136] .

[0137] The y-direction cumulative distribution is observed from the top, and this distribution is the integral of the three-dimensional plume in the z direction, which can be described by the following formula to describe the shape of the plume.

[0138] .

[0139] Multiplying the two plane formulas obtains the three-dimensional formula.

[0140] ​σy and σz are atmospheric dispersion parameters in y direction and z direction respectively, both of which are functions of atmospheric stability and horizontal distance x from wind direction, and can be calculated by the following formulas:

[0141] σy = axb;

[0142] σz = cx+d + f;

[0143] b is a regression index of horizontal diffusion parameter;

[0144] d is a regression index of vertical diffusion parameter;

[0145] a is a regression coefficient of horizontal diffusion parameter;

[0146] c is a regression coefficient of vertical diffusion parameter;

[0147] x is horizontal distance from air outlet;

[0148] The parameters in the above formulas are obtained by fitting the values of multiple actual measurement experiments.

[0149] The wind speed U in the above parameters can be tested by a wind speed monitor, and the discharge rate Q is designed according to the rotating speed of the axial flow fan, the static pressure of the air outlet, and the functional structures (turbulent flow dividing plate, flow guiding conical surface, flow guiding grid 2031 surface, etc.) of the 8-shaped air outlet, the discharge rate Q contains a hidden parameter, and the smoke outlet requires a laminar flow state; different discharge rates Q are determined according to different wind speeds U, and the best fitting data under the condition of ensuring the laminar flow state are obtained.

[0150] In this embodiment, the fan speed is dynamically controlled under different wind speeds to effectively control the concentration of the jet flow smoke; by establishing a correlation data model between different smoke concentrations and different vehicle speeds, the driving safety in each environment is effectively ensured, and the function of flexible smoke blocking is achieved.

[0151] In this embodiment, the difference from the embodiment 1 is that, as shown in Figure 1 and Figure 2 The display screen 105, warning light and directional broadcast 104 are installed on the side of the box body 1 facing the driving direction, and the warning light and directional broadcast 104 are located at the upper part of the box body 1 and above the display screen 105.

[0152] In this embodiment, the display screen 105 is an LED display screen 105 with a point spacing of 5 mm, the warning light is a red and blue flashing light 102 in the prior art, and the directional broadcast 104 is a long-distance directional broadcast 104 controlled by multi-channel DSP wave speed.

[0153] The box body 1 in the embodiment is also provided with a road direction video monitoring unit 103 and a roadside video monitoring unit 109. The road direction video monitoring unit 103 is located at the same side as the warning light and is centrally arranged. The roadside video monitoring unit 109 is located at the same side as the deflector grille surface and is arranged above the deflector grille surface.

[0154] In the embodiment, two lifting rings 113 are connected to the top of the box body 1, facilitating hoisting.

[0155] As shown in the combination Figure 19 The box body 1 is internally provided with a control system box 114. In the embodiment, a sealing plate 116 is internally provided in the box body 1 by means of screws. The control system box 114 is fixedly arranged on the sealing plate 116. A switch assembly 115 is arranged on the control system box 114. A wire passing groove 117 is also arranged on the sealing plate 116. The cables used in the entire system can be located in the wire passing groove 117.

[0156] The control system in the control system box 114 can control the start or stop of the smoke forming unit and the light curtain strip forming unit, and control the start or stop of the directional broadcast 104, the fan, the smoke storage tank, the red and blue flashing light 102, and the display screen 105.

[0157] The control system in the embodiment is located in the control system box 114. The control system includes a battery, a control board, a switch, and a serial port server. As shown in the combination Figure 24 and Figure 25 As shown in the combination, the device has a one-key start function. The whole device is controlled by a three-layer logic architecture control circuit (application layer, network layer, and hardware layer). The device adopts a chemical smoke forming method, which has a fast smoke forming speed and can complete the start and stable operation of all functions within 3S. Similar products on the market use a heating smoke forming method, which has a slow smoke forming speed and a start time greater than 5S. According to the calculation at a speed of 120Km / h, 2S can travel 66m. The device can greatly improve the emergency response capability and enhance the safety induction capability.

[0158] In addition, the device can analyze the video data in the roadside and road direction directions, update the early warning voice information and video picture text information in real time, and determine the opening and closing state of the light smoke component in real time. Similar devices on the market do not have a real-time updating strategy and do not have an active correction function. They cannot update the strategy according to the real-time blocking effect of the road section, reasonably guide the drivers and passengers to orderly and safely guide, and avoid secondary accident injuries.

[0159] The specific implementation process is as follows:

[0160] The device mixes light and smoke to form a light smoke screen wall; the device broadcasts 104 accident content through long-distance directional broadcasting controlled by multi-channel DSP wave speed; the device adjusts the smoke flow speed level and concentration through the wind speed monitor 101; the device performs dynamic video warning or high-light text warning through the display screen 105; the device performs high-intensity warning through the red and blue flashing light 102; the device can observe the real-time road condition information of the blocked road section through the video monitoring of the two directions of the roadside and the road direction, and forms combined strategy update warning voice information and video picture text information after video data collection and analysis, and determines the opening and closing state of the light smoke component in real time; the device accurately provides emergency safety induction for drivers and passengers through multi-dimensional stimulation factors.

[0161] The device can be controlled locally or remotely, and integrated with a comprehensive management and control platform, which can be manually controlled independently, one-key started, automatically controlled according to the installation site environment conditions, and the like.

[0163] In this embodiment, the box body 1 on the side where the display screen 105 is installed is also provided with an openable and closable module door plate 106, and the display screen 105 is installed on the module door plate 106. Figure 19 As shown in the figure, the control system box 114 is installed inside the box body 1 on the side of the module door plate 106, and the control system box 114 can be repaired and installed by opening the module door plate 106, and when in normal use, the module door plate 106 is closed to block the inside of the box body 1 and the control system box 114, and a sealing strip is arranged in the box body 1 to ensure the waterproof sealing of the box body 1.

[0164] Embodiment 7, the difference between this embodiment and embodiment 1 is that, as shown in Figure 20 The bottom of the box body 1 is connected with a closed fence 110, the bottom of the closed fence 110 is provided with mounting holes 111 around, and the bottom of the box body 1 is provided with a wire inlet hole 112, which is located inside the closed fence 110. Specifically, the closed fence 110 is integrally formed with the box body 1, and the closed fence 110 forms a closed space around, and mounting plates 1110 are integrally connected on both sides of the closed fence 110, and mounting holes 111 are arranged on the mounting plates 1110, so that when the box body 1 is installed and fixed, bolts can be screwed into the mounting holes 111 on the mounting plates 1110 to fix the box body 1 on the ground.

[0165] The wire inlet hole 112 is located at the bottom of the box body 1 and inside the closed fence 110, so that the cable can be inserted through the wire inlet hole 112, and the cable can be hidden.

[0166] The closed fence 110 in the embodiment lifts the bottom of the box body 1, which can prevent water and animals from entering the box body 1 and damaging the components inside the box body 1.

[0167] It is to be understood that the above description is illustrative of the application and not in any sense limiting of the present application.
