Description

Technical Field

[0001] The present invention relates to an early warning system, and in particular to a safety early warning system for highway construction applied in the technical field of safety early warning. Background Art

[0002] At present, the mileage of highway construction is increasing, and the road surface that needs maintenance every year is also increasing. Highways with damaged road surfaces need to be renovated. In order to reduce the mutual impact between highway maintenance and moving vehicles, the construction area will be isolated by guardrails. At the same time, in order to remind vehicle drivers to pay attention to the construction area, the construction site needs to be clearly marked and warned.

[0003] The specification of Chinese patent CN202410520629.2 discloses "A safety warning system for intensive maintenance operations on highways based on closed traffic", which issues a warning when non-construction vehicles intrude or construction vehicles and workers approach each other, so that construction vehicles and maintenance workers can receive warning messages in time and avoid possible traffic risks. The specification of Chinese patent CN202210020691.6 discloses "A new type of anti-collision buffer bar", which makes it suitable for different application scenarios by adjusting the telescopic column to a suitable height. At the same time, the control device can control the extension and retraction of the telescopic column according to the speed of the object on the outside detected by the speed measuring radar, so as to drive the guardrail to flip and tilt, and prevent the high-speed object from directly colliding with the guardrail when the guardrail is in a vertical state, resulting in personal injury and damage to the guardrail due to the high-speed collision between the object and the guardrail. The specification of Chinese patent CN202420236625.7 discloses "A toll station anti-collision device", which uses a blocking mechanism, through the cooperation of grooves, mounting frames, through grooves, motors, drive wheels, rotating shafts, rotating blocks, driven wheels, speed bumps, and cone rods, and relies on the cone rod to puncture the tires of the vehicle that rushes the card, which can effectively intercept the vehicle that rushes the card and improve public safety.

[0004] Since the construction area will be enclosed by fences, vehicles traveling outside the fences can clearly observe the warning information, and drivers can actively change lanes and detour. Construction workers inside the fences lack perception of the external environment, so they cannot make correct risk avoidance behaviors when they receive the warning information. At the same time, guardrails and walls are usually equipped with impact-resistant buffer facilities to cushion the impact force of vehicles, and forced stopping facilities are also used when necessary. When a vehicle drives abnormally towards the construction area, the existing fence facilities and warning equipment can hardly protect the construction workers, nor can they reduce the losses caused by collision accidents. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that construction workers cannot take correct risk avoidance actions when receiving warning information, and existing fence facilities and warning devices are difficult to play a role in protecting construction workers, nor can they reduce the losses caused by impact accidents.

[0006] To solve the above problems, the present invention provides a safety warning system for highway construction. The system includes a construction fence wall. At both ends of the construction fence wall away from the roadside, warning column modules are fixedly installed. At both ends of the construction fence wall close to the roadside, entrances and exits are provided. At the top of the warning column module, an acoustic-optic warning board and a ranging camera module are fixedly installed. The two sides of the acoustic-optic warning board are respectively arranged as an employee warning panel and a vehicle warning panel corresponding to the inside and outside of the construction fence wall. The employee warning panel is used to send warning information to construction workers, and the vehicle warning panel is used to send warning information to highway vehicles. Vehicle deflection modules are laid on the outer sides of both ends of the construction fence wall. The vehicle deflection modules are laid obliquely towards the roadside corresponding to the warning column modules. The top of the vehicle deflection module is equidistantly provided with movable grooves. Inside the movable grooves, deflection rollers are rotatably connected. At both ends of the deflection rollers, breaking wall cylinders are sleeved. Inside the breaking wall cylinders, winding wheel nets are filled. One end of the winding wheel net is fixedly connected with a winding net belt. The surface of the winding net belt is fixedly inlaid with barbed nails, and the barbed nails penetrate through the breaking wall cylinders and extend out.

[0007] In the above safety warning system for highway construction, the ranging camera module is used to conduct video monitoring on abnormal vehicles driving towards the construction fence wall, and according to the monitoring situation, the acoustic-optic warning board is used to alarm the vehicles and construction workers, facilitating the safe evacuation of workers.

[0008] As a further improvement of the present application, crack grooves are equidistantly provided on the surface of the breaking wall cylinder, and the breaking wall cylinder is made of plastic. The winding wheel net is made of a high-strength fiber net and metal wires. The breaking wall cylinder breaks along the crack grooves, facilitating the removal of the winding wheel net inside the breaking wall cylinder. The high-strength winding wheel net effectively improves the ability to lock the wheels, thereby realizing the emergency braking of abnormal vehicles.

[0009] As a further improvement of the present application, buffer water horses are placed in the included angle space between the vehicle deflection module and the construction fence wall. The buffer water horses are arranged in a triangular shape. The abnormal vehicles after braking hit the buffer water horses, realizing the buffering of the vehicle impact force, effectively protecting the vehicle driver, and reducing the impact of the vehicle collision on the construction fence wall.

[0010] As a further improvement of the present application, a rotating shaft is rotatably connected inside the vehicle deflection module. A bevel gear meshing transmission connection is provided between the middle of the rotating shaft and the deflection roller. The rotating shaft rotates and adjusts the deflection roller through the bevel gear meshing transmission method, adjusting the angle of the protruding barbed nails to avoid the barbed nails piercing the tires, thereby avoiding losses to vehicles driving at low speed.

[0011] As another improvement of the present application, a module control console is fixedly connected to one end of the vehicle deflection module close to the roadside. The output end of the distance measurement and camera module is connected to the input end of the module control console. A rotary motor is fixedly connected to the bottom of the module control console, and a rotary shaft is fixedly connected to the output end of the rotary motor. When the distance measurement and camera module detects an abnormal vehicle approaching at a low speed, the distance measurement and camera module transmits the monitoring signal to the module control console, and the module control console adjusts the rotation of the rotary shaft through the rotary motor.

[0012] As a supplement to another improvement of the present application, a nail groove is provided at one end of the movable groove along the rotation direction of the rotary motor. The barbed nail corresponds to the nail groove, and the barbed nail after rotation adjustment enters the nail groove and is hidden, thus effectively preventing the barbed nail from piercing the tire.

[0013] As a supplement to another improvement of the present application, a protective shell is sleeved outside the wall-breaking cylinder. The cross-section of the protective shell is semicircular. The upper opening of the nail groove corresponds to one end of the protective shell. The protective shell is made of stainless steel material, and the upper surface of the protective shell is polished smoothly. The protective shell provides protection for the wall-breaking cylinder. After the barbed nail is hidden, the semicircular protective shell covers the wall-breaking cylinder, thus preventing the wheel from directly pressing on the wall-breaking cylinder, effectively preventing the wall-breaking cylinder from being damaged due to pressure, and the surface of the stainless steel protective shell is smooth, facilitating the tire to cross the protective shell.

[0014] As another improvement of the present application, a clamping groove piece is fixedly connected to one end of the protective shell. The clamping groove piece is clamped with the deflection roller. The protective shell is clamped and fixed on the deflection roller by the clamping groove piece, realizing the rotation movement of the protective shell following the deflection roller. When the movement of the protective shell is restricted, it can stop following the rotation of the deflection roller.

[0015] In summary, the present invention uses the distance measurement and camera module to perform camera monitoring on abnormal vehicles approaching the construction fence wall, and uses the sound and light warning board to alarm the vehicles and construction personnel according to the monitoring situation, facilitating the correct safety evacuation behavior of the working staff. At the same time, before the abnormal vehicle is about to hit the construction fence wall, the wheels of the vehicle pass through the vehicle deflection module. Using the rolling ability of the deflection roller, the wheels are deflected towards the roadside to change the driving direction of the abnormal vehicle, thus effectively preventing the vehicle from directly hitting the construction fence wall, effectively improving the protection effect on the construction personnel inside the construction fence wall, and by piercing the barbed nail into the wheel, the wall-breaking cylinder is broken, and the pulled-out entanglement net wraps and locks the wheel, realizing the braking effect on the abnormal vehicle, effectively reducing the destructive force of the vehicle impact, and realizing the protection of the vehicle driver.

[0018] The following will make a detailed description of the two embodiments of this application with reference to the accompanying drawings.

[0019] The first embodiment: Figures 1 to 3Shown is a safety warning system for highway construction. The system includes a construction fence wall 1. At both ends of the construction fence wall 1 away from the roadside, warning post modules 2 are fixedly installed. At both ends of the construction fence wall 1 close to the roadside, entrances and exits 101 are provided. On the top of the warning post module 2, an acoustic-optical warning board 201 and a ranging camera module 202 are fixedly installed. On the two sides of the acoustic-optical warning board 201 corresponding to the inside and outside of the construction fence wall 1, an employee warning panel 203 and a vehicle warning panel 204 are respectively arranged. The employee warning panel 203 is used to send warning information to construction workers, and the vehicle warning panel 204 is used to send warning information to highway vehicles. In the angular space between the vehicle deflection module 3 and the construction fence wall 1, buffer water horses 102 are placed. The buffer water horses 102 are arranged in a triangular pattern. When a braked abnormal vehicle hits the buffer water horses 102, the impact force of the vehicle is buffered, effectively protecting the vehicle driver and reducing the impact of the vehicle collision on the construction fence wall 1; During highway maintenance construction, the construction fence wall 1 is installed around the construction area for isolation. Construction workers carry out highway maintenance construction in the isolated area, and vehicles traveling on the highway bypass the isolated area. However, when an abnormally traveling vehicle directly drives into the construction area isolated by the construction fence wall 1, the judgment basis can be to place road cones in a designated area. The road cones are used to demarcate monitoring areas in front of and behind the construction fence wall 1. Vehicles driving into this area are determined to be abnormally traveling vehicles. The ranging camera module 202 conducts video monitoring on the approaching abnormal vehicle and uses the acoustic-optical warning board 201 to give an alarm according to the monitoring situation. The employee warning panel 203 issues an alarm to construction workers and indicates the direction of the approaching vehicle, guiding construction workers to evacuate the construction area from the designated entrances and exits 101. The vehicle warning panel 204 gives an alarm to vehicles traveling outside the construction area, facilitating normal traveling vehicles to make evasive maneuvers.

[0020] Figure 1 and Figures 4 to 6 Shown is that vehicle deflection modules 3 are laid on the outside of both ends of the construction fence wall 1. The vehicle deflection modules 3 are laid obliquely towards the roadside corresponding to the warning post modules 2. At equal intervals on the top of the vehicle deflection module 3, movable grooves 301 are provided. Inside the movable grooves 301, deflection rollers 302 are rotatably connected. At both ends of the deflection rollers 302, breaking wall cylinders 303 are sleeved. Inside the breaking wall cylinders 303, winding wheel nets 304 are filled. One end of the winding wheel net 304 is fixedly connected to a winding net belt 305. On the surface of the winding net belt 305, barbed nails 306 are fixedly inlaid. The barbed nails 306 penetrate through the breaking wall cylinders 303 and extend out. At equal intervals on the surface of the breaking wall cylinders 303, crack grooves 307 are provided. And the breaking wall cylinders 303 are made of plastic, and the winding wheel nets 304 are made of high-strength fiber nets and metal wires. The breaking wall cylinders 303 break along the crack grooves 307, facilitating the removal of the winding wheel nets 304 inside the breaking wall cylinders 303. The high-strength winding wheel nets 304 effectively improve the ability to lock the wheels, thereby realizing the emergency braking of abnormal vehicles; Before the abnormal vehicle is about to hit the construction fence wall 1, the wheel of the vehicle passes through the vehicle deflection module 3, and the wheel rolls with the deflection roller 302, causing the wheel to deflect toward the side of the road to change the driving direction of the abnormal vehicle, thereby effectively avoiding the vehicle from directly hitting the construction fence wall 1, and effectively improving the protection effect on the construction personnel in the construction fence wall 1. During the rolling contact between the wheel and the deflection roller 302, the barb nail 306 penetrates into the wheel, and the wheel uses the barb nail 306 to pull out the wheel net 304, and the wall breaking cylinder 303 is broken simultaneously, so that the pulled out wheel net 304 can wrap the locked wheel, thereby achieving a braking effect on the abnormal vehicle, effectively reducing the destructive force of the vehicle collision, and providing protection for the driver of the vehicle.

[0021] The second implementation method: Compared with the first embodiment, the main new addition is a rotating shaft 4, and the specific new structure is as follows, and the rest of the structure is consistent with the first embodiment.

[0022] Figures 7 to 10 As shown, the internal rotation of the vehicle deflection module 3 is connected with a rotating shaft 4, and the rotating shaft 4 is connected to the middle part of the deflection roller 302 by a bevel gear meshing transmission. The rotating shaft 4 adjusts the rotation of the deflection roller 302 by means of a bevel gear meshing transmission, and adjusts the angle of the extended barb nail 306 to avoid the barb nail 306 puncturing the tire, thereby avoiding damage to vehicles coming at a low speed. The end of the vehicle deflection module 3 close to the road side is fixedly connected to a module console 401, the output end of the ranging camera module 202 is connected to the input end of the module console 401, and the bottom of the module console 401 is fixedly connected to the vehicle deflection module 3. A rotating motor 402 is fixedly connected, and the rotating shaft 4 is fixedly connected to the output end of the rotating motor 402. When the ranging camera module 202 detects an abnormal vehicle approaching at a low speed, the ranging camera module 202 transmits a monitoring signal to the module console 401. The module console 401 realizes the rotation adjustment of the rotating shaft 4 through the rotating motor 402. A nail groove 403 is opened at one end of the movable groove 301 along the rotation direction of the rotating motor 402, and the barb nail 306 corresponds to the nail groove 403. The barb nail 306 after rotation adjustment enters the nail groove 403 and is hidden, thereby effectively preventing the barb nail 306 from piercing the tire; When the speed of the abnormal moving vehicle monitored by the ranging camera module 202 is lower than the warning speed, the ranging camera module 202 transmits the monitoring signal to the module console 401. The module console 401 realizes the rotation adjustment of the rotating shaft 4 through the rotating motor 402. The rotating shaft 4 drives the deflection roller 302 to rotate by means of bevel gear meshing transmission, and retracts the protruding barbed nails 306 into the nail groove 403, that is, the barbed nails 306 enter the nail groove 403 and are hidden. When the subsequent wheels cross the vehicle deflection module 3, it effectively avoids the barbed nails 306 piercing through the wheels, thus effectively avoiding the locking and braking ability of the driving entanglement net 304 on the wheels, effectively avoiding the barbed nails 306 piercing the tire, and effectively reducing the loss of the vehicle.

[0023] Figures 9 to 10 As shown, a protective shell 404 is sleeved outside the wall-breaking cylinder 303. The cross-section of the protective shell 404 is semicircular. The upper opening of the nail groove 403 corresponds to one end of the protective shell 404. The protective shell 404 is made of stainless steel material, and the upper surface of the protective shell 404 is polished smoothly. The protective shell 404 provides protection for the wall-breaking cylinder 303. After the barbed nails 306 are hidden, the semicircular protective shell 404 covers the wall-breaking cylinder 303, thus avoiding the wheels directly pressing on the wall-breaking cylinder 303, effectively avoiding the wall-breaking cylinder 303 being damaged due to pressure, and the surface of the stainless steel protective shell 404 is smooth, facilitating the tire to cross the protective shell 404. One end of the protective shell 404 is fixedly connected with a clamping groove piece 405, and the clamping groove piece 405 is clamped with the deflection roller 302. The protective shell 404 is clamped and fixed on the deflection roller 302 by using the clamping groove piece 405, realizing the protective shell 404 to rotate and move following the deflection roller 302, and can stop following the deflection roller 302 when the movement of the protective shell 404 is restricted; When the deflection roller 302 rotates and adjusts, the protective shell 404 realizes the rotation of the protective shell 404 following the deflection roller 302 by means of the clamping of the clamping groove piece 405 and the deflection roller 302, achieving the effect that the protective shell 404 covers the outer surface of the wall-breaking cylinder 303. When the subsequent wheels cross the vehicle deflection module 3, it effectively avoids the wheels directly pressing on the wall-breaking cylinder 303, thus effectively avoiding the wall-breaking cylinder 303 being damaged due to compression, and reducing the damage degree of the vehicle deflection module 3.

[0024] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the protection scope is not limited to this. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
