[0043] See Figure 2 The power source of the motor 2 of the device comes from the municipal power grid, and the device further comprises a controller for controlling the rotation of the motor 2. The controller is electrically connected with a speed measuring radar and a laser sensor, and the controller is also electrically connected with the aforementioned motor. The model of the speed measuring radar is TBR-220, which is erected beside the stake through a support, and is used to monitor the speed of the vehicle when passing through the stake of the aqueduct within a range of 0.3m radius of the stake. The ultrasonic wave emitted by the speed measuring radar is reflected after hitting the vehicle, and the distance between the speed measuring radar and the vehicle is obtained by calculating the time of emitting and returning of the ultrasonic wave and multiplying the speed of sound. The vehicle speed is obtained by dividing the difference between the two measured distances by the time, which belongs to the prior art. Because the speed measuring radar emits ultrasonic waves in the form of waves, there are reflected ultrasonic waves at any time and any position in the process of the vehicle hitting the stake on the road, and the speed of the vehicle can be measured by the speed measuring radar.

[0044] The laser sensor is bolted on the post, and the laser sensor is a laser sensor of LMS series. The emitted light is reflected back after irradiating the object. The distance between the vehicle and the post is obtained by calculating the time from emission to reflection and multiplying the speed of light. As the laser sensor emits multiple beams of light, each beam has a different direction, so the laser sensor can detect the distance between the vehicle and the post from multiple directions, ensuring that the vehicle will not hit the post from a blind spot.

[0045] The use process of the device is:

[0046] For an anti-collision device, the laser sensor and the speed measuring radar in the anti-collision device monitor the distance and speed of the object (vehicle) approaching the post respectively and simultaneously, and transmit to the controller.

[0047] When the controller monitors that the speed of an object approaching the speed measuring radar is greater than the set speed threshold (25 km / h) through the speed measuring radar, and at the same time, the distance between the object and the post is less than the set threshold (0.2 m) through the laser sensor, it indicates that the object has the possibility of fast impact on the post. Figure 2 When the left speed measuring radar monitors that the vehicle approaches the left post at a speed greater than 25 km / h, and the left laser sensor monitors that the vehicle is located at a distance less than 0.2 m from the left post, the left speed measuring radar and the left laser sensor send a monitoring signal to the corresponding controller on the left, and the controller receives the monitoring signal and sends a start signal to the corresponding motor. After receiving the start signal, the corresponding motor rotates quickly.

[0048] After the motor rotates a circle, the disc cam will move to the left as a whole against the first sliding block, connecting rod, first abutment block, and first needle due to the change in the diameter of the disc cam, so that the first needle pierces the first gas bottle during the left movement. The gas in the first gas bottle passes through the device cavity and the first gas channel to inflate the first air bag. Because the first sliding groove and the second sliding groove are closed by the first rubber ring and the second rubber ring respectively, the gas in the first gas bottle will not enter the second gas channel, and the first gas bottle will not affect the second air bag. The first spring is further compressed. Because the pressure of the first gas bottle is much greater than that of the second air bag, the inflation speed is extremely fast. Moreover, multiple air bags on a post are inflated simultaneously, and the inflation amount of the air bag is guaranteed, so theoretically the vehicle impact force can be buffered.

[0049] After the above-mentioned whole moves to the left, the second resisting block, the second lancet and the guide ring as a whole move downward because of the interference of the first and second inclined surfaces, and the second gas cylinder is punctured, the gas in the second gas cylinder flows into the second air bag through the second air duct and the second air tube, the second air bag is inflated, the inflation openings of the first and second air bags are provided with one-way valves, the gas can only enter but not exit. The second spring is further compressed. The first and second gas cylinders are both filled with high-pressure gas, so the above-mentioned flow is the flow due to the pressure difference.

[0050] When the disc-shaped cam rotates to one circle and is reset, the above-mentioned further compressed stroke of the first and second springs is reset. The above-mentioned two wholes are also reset.

[0051] Based on the above-mentioned ideal embodiment of the present application, through the above-mentioned description, relevant staff can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and must be determined according to the scope of claims.
