Description
Technical Field
The invention relates to the technical field of traffic warning devices, in particular to a highway fault warning device.
Background
When an accident or a fault occurs to the vehicle on the expressway, if the vehicle can move, the vehicle should move to an emergency lane as soon as possible, and a warning sign is placed according to the requirement; if the vehicle cannot move, the warning board is placed behind the lane occupied by the vehicle according to the requirement, and the vehicle can give an alarm in time to ask for help. The traffic warning sign needs to be placed outside the rear 150 of the lane occupied by the vehicle, otherwise, it will be overtaken once a secondary traffic accident occurs.
However, many drivers often cannot carry warning boards by themselves, traffic management departments cannot routinely check whether vehicles carry warning boards, so that when accidents or faults occur on highways, no warning boards can be placed, secondary traffic accidents are extremely easy to occur, especially when weather with low visibility such as heavy rain, heavy fog and the like or accidents or faults occur at road curves, if the traffic warning boards cannot be placed reasonably, the occurrence probability of the secondary traffic accidents can be greatly improved, and many highway large-scale interlinked accident cases occur every year in China, so that the accidents not only cause the congestion of the highways, but also bring irrecoverable disasters to families and economic losses of accident parties. Therefore, when advocated the vehicle to carry the traffic warning board by oneself according to the regulation, need set up a sharing traffic warning board on the highway for forget to carry the accident principal of traffic warning board and provide the use, avoid taking place the secondary traffic accident.
The prior patent (publication number: CN 108086191A) discloses a traffic warning board, a warning board body is placed in a protection box, the protection box is arranged on a highway guardrail, the distance between adjacent protection boxes is 100-200 m, the warning board body is locked in the protection box through a warning board lock, the warning board lock is unlocked and taken through an identity card brushing mode, an alarm working state switch is closed after the identity card is brushed on an identity card identifier, the alarm can be used, a high-speed traffic management service terminal in wireless connection with the alarm can learn that an accident or fault occurs on a highway through pressing the alarm, and the accident position can be positioned through positioning the position of the warning board body. The reason that the identity card can be taken by brushing is to avoid malicious taking, stealing and other time, so that the identity card can be shared and taken by a real-name system. Therefore, by the method, when the vehicle on the expressway has an accident or a fault, a driver can use the vehicle immediately, so that the occurrence of a secondary traffic accident is avoided, and the occurrence probability of the secondary traffic accident on the expressway is greatly reduced; the traffic warning sign is convenient for the expressway traffic management service department to carry out accident positioning by pressing down the alarm, so that the expressway traffic management service department can quickly lock the accident or fault vehicle position, and the follow-up work can be conveniently and quickly completed.
However, a traffic warning board designed by the above design has some drawbacks in practical application: if the traffic warning board is set up according to 100-200 m, it not only consumes too much cost, but also is difficult to install, and because the traffic warning device is usually one of the configurations that the vehicle enterprise must assemble when producing the vehicle, and can be installed in the fixed position in the vehicle, so there is no problem that the vehicle owner forgets to carry, the existing traffic warning board has a single structure, most of ordinary reflective tripods are placed on the ground, and because the tripods are shorter, and the vehicle speed on the expressway is faster, the rear vehicle can not see the warning board clearly due to improper observation, and further secondary traffic accidents are easily caused, and the existing warning board has fewer functions, and can not give out warning signals to the rear vehicle owners on the expressway.

The working process of the expressway fault warning device provided by the embodiment of the invention is as follows:
when the warning board 2 needs to be lifted and the warning board 2 is stably placed on the ground:
the first step: firstly, a person on the automobile turns on a hazard warning lamp carried by the automobile, takes out the traffic warning device from the automobile, and then walks to 200 meters behind the accident automobile along the side of the expressway;
and a second step of: then the torsion block 26 is rotated to rotate the bidirectional screw rod 20, so that the two nuts 21 horizontally move along the direction of the limit groove 27 to gradually approach, and in the process, the two transmission parts 23 push the warning board 2 to vertically move upwards until the warning board 2 rises to the maximum limit;
and a third step of: then, the stabilizing plate 31 is pulled to separate the permanent magnetic strips on the stabilizing plate 31 from the third permanent magnetic blocks 35, and the stabilizing plate 31 slides outwards in the fixing groove 30 until the first permanent magnetic blocks 32 and the second permanent magnetic blocks 33 are adsorbed together, so that the traffic warning device can be lifted and stably placed on the ground, and the warning board 2 matched with the reflective material can play a warning role on a rear vehicle.
When the traffic warning device needs to be pronounced:
the first step: firstly, a warning device which is lifted and lengthened is quickly placed at a position 200 meters behind an accident car, then a servo motor 14 and an alarm lamp 36 are started, a rotating shaft 12 drives a cam 13 to rotate, the cam 13 is separated from a sliding plate 8, at the moment, a return spring 11 horizontally pulls the sliding plate 8 due to self tension, two rotating pieces 5 rotate around a fixed shaft 4, two sounding metal blocks 6 are impacted together to make a sound, and in the process, a sliding block 9 slides along a guide rod in a mounting groove;
and a second step of: then the sound is transmitted into the sound guide cover 19, then the sound is divided into two parts through the sound collecting tube 17 and the two sound outlets 18, finally the sound is transmitted backwards through the two sound outlets 18, and the two sound producing metal blocks 6 are impacted once every time the cam 13 rotates one circle;
and a third step of: while the traffic warning device sounds, the warning light 36 will light up to flash, and a warning signal can be sent to the rear vehicle.
In summary, according to the device provided by the embodiment of the invention, by rotating the torsion block 26, the two driving parts 23 can push the warning board 2 to move upwards until the warning board 2 rises to the maximum limit, then the stabilizing plate 31 is pulled, the stabilizing plate 31 can slide out of the fixing groove 30, and finally the warning board 2 matched with the reflective material can play a role in warning the rear car. In addition, place warning device in accident car rear 200 meters departments, then start servo motor 14 and warning light, make cam 13 and slide 8 break away from, reset spring 11 can pull slide 8 level this moment, and make two pronunciation metal pieces 6 striking at the sound, the sound is propagated towards the rear through sound guiding cover 19 afterwards, sound collecting pipe 17, sound outlet 18, sound guiding groove 16 and sound amplifying groove 15, the warning light of cooperation scintillation simultaneously, can send warning signal to the rear car, the problem that the current traffic warning device is because of mostly can't send danger signal to the rear car, lead to the reaction time of rear car not enough and take place the secondary traffic accident easily has been realized through the transmission of sound and the cooperation of warning light effectively with accident signal to the effect in rear.
