The invention discloses a car lamp distance and passing light automatic converting device in car meeting at night and a method thereof. The device comprises a light intensity recognition module for collecting the light intensity of car lamps of a coming car in car meeting, a light source judgment module and a car lamp control module, wherein the light source judgment module is connected with the light intensity recognition module and used for comparing the collected light intensity with a first threshold value so as to generate a control signal, the first threshold value is the set and allowable light intensity maximum value of the car lamps of the coming car when the naked eyes can see the road condition clearly, and the car lamp control module is connected with the light source judgment module and used for controlling car lamps of a car of a user to conduct conversion of flickering and distance and passing light according to the generated control signal after the light source judgment module completes judgment. The device can detect the light intensity of the car lamps of the coming car in car meeting and judge whether the intensity exceeds a limiting threshold value or not, if the intensity exceeds the limiting threshold value, the car lamps of the car of the user is arranged to be passing light, meanwhile, the coming car is prompted through the car lamp flickering mode, and therefore the car running environment can be improved.

The present invention relates to the field of intelligent street lamps, in particular to a wind-solar hybrid intelligent street lamp, comprising a lamp post and a first transmission cavity arranged in the lamp post, wherein the top wall of the first transmission cavity is rotatably provided with an extension extending to the first transmission cavity. The first rotating shaft outside the transmission cavity, the outer surface of the first rotating shaft is fixed with a fan wheel, the outer surface of the fan wheel is fixed with fan blades, and the outer surface of the first rotating shaft is fixed with a fan wheel located above the fan wheel. Wind power device, the wind power device is driven by wind to generate electricity, the invention provides a wind-solar hybrid intelligent street lamp, which can improve the efficiency of the wind power device, and can fold the solar panel when the wind is too strong to avoid damage to the photoelectric device, and at the same time In rainy and foggy weather, the state of the lighting device is adjusted to provide a good lighting environment and reduce the probability of car accidents caused by insufficient lighting intensity.

The invention provides a concrete mixer truck. The concrete mixer truck comprises a truck body and a rotary drum, and the rotary drum is sleeved with a loop and is matched with the loop through a circular groove to rotate in the loop around the axis of the rotary drum. The loop is fixed onto a horizontal rotating plate which is arranged on the truck body, and the horizontal rotating plate is capable of rotating around own axis and has a rotation pretension force. The axis of the horizontal rotating plate and the axis of the rotary drum are intersected, and an intersection is positioned between the center of gravity of the rotary drum and the end, close to a truck head, of the rotary drum. When the truck body is in a static state, an included angle between the axis of the rotary drum and a median section of the truck body is 15-30 degrees. The peripheral wall of the rotary drum is provided with a gear ring which is driven by a driving mechanism fixed to the loop. The concrete mixer truck has the advantages that safety in sudden brake can be evidently improved, and consequently probability of car accidents is reduced.

The invention discloses an anti-explosion lining of an automobile tire. The anti-explosion lining consists of two parts, namely, an insulating layer 2 and a puncture-proof layer 3. Under the condition that a conventional tire production process and the conventional road situation are not changed, tire explosion factors can be effectively avoided. The probability of traffic accidents is technically reduced.
