A plurality of pins are arranged on the locking member 372, and a plurality of slots capable of cooperating with the pins are arranged on the inner side wall of the first fixing rod 32.

[0036] See Figures 1 to 7 , one end of the positive rotation shaft 36 is rotatably connected to a positive rotation gear 363. A positive ratchet wheel is arranged on the positive rotation gear 363 (the positive rotation shaft 36, the positive rotation gear 363 and the positive ratchet wheel are concentric). A positively rotatable positive pawl is rotatably connected to the positive rotation shaft 36. One end of the reverse rotation shaft 37 is rotatably connected to a reverse rotation gear 374. A reverse ratchet wheel is arranged on the reverse rotation gear 374 (the reverse rotation shaft 37, the reverse rotation gear 374 and the reverse ratchet wheel are concentric).

[0037] See Figures 1 to 7 , preferably, the driving member 372 is a rotary motor, which can provide sufficient power.

[0038] See Figures 1 to 7 , preferably, the detachable connection methods in the present utility model can all adopt bolt connection, snap connection, etc., and users should select appropriate connection methods according to actual situations.

[0039] See Figures 1 to 7 , preferably, the driving member 372 is electrically connected to the photovoltaic panel 3 (or other energy storage components), and the self-power supply of the device can be realized.

[0040] During the implementation of the present utility model: on the road surfaces of overpass bridges, expressways, etc. in the early morning, due to the high air humidity and the rapid change of ground temperature, black ice road surfaces are likely to form. At this time, if a vehicle passes by, when the vehicle brakes, the black ice road surface will reduce the tire friction, resulting in the vehicle skidding and causing accidents, resulting in property losses and even personal safety losses. Through the detection head 5, the present device can measure the surface resistance value and temperature of the ground, and comprehensively judge by combining the data collected by the first atmospheric data sensor 23, the second atmospheric data sensor 33, the wind data sensor 35, etc., and can effectively and real-time monitor and determine whether the road surface constitutes icing conditions, and display the warning information on the upper server management platform, forecast the road surface icing conditions of the corresponding node sections, and at the same time, can accurately give the air temperature and humidity, wind force, rainfall, etc. of the corresponding node range mileage, improving the real-time, accuracy and reliability of the node road surface ice condition environment monitoring.

[0041] When it is necessary to adjust the angle of the photovoltaic panel 3, the driving member 381 rotates in reverse. At this time, the reverse ratchet and the reverse ratchet pawl cooperate, and the positive ratchet does not cooperate with the positive ratchet pawl. The reverse rotation gear 374 drives the reverse shaft 37 to rotate, and the forward rotation gear 363 cannot drive the forward shaft 36 to rotate. The reverse shaft 37 drives the sleeve shaft 371 to rotate, and the two mating blocks move away from each other, so that the insertion pin is disengaged from the insertion slot, unlocking the movable seat 361. Then the driving member 381 rotates forward, the positive ratchet and the positive ratchet pawl cooperate, and the reverse ratchet does not cooperate with the reverse ratchet pawl. The movable seat 361 reciprocates along the forward shaft 36 to realize the adjustment of the angle of the photovoltaic panel 3.

[0042] The present utility model provides a road black ice detection and warning device, and its beneficial effects are as follows:

[0043] 1. Through the detection head arranged on the side of the highway curbstone, the asphalt surface resistance value and temperature can be measured, the temperature and humidity changes on the highway surface can be monitored in real time, and the temperature and humidity changes in the atmospheric environment can also be measured, and the road surface icing conditions, air humidity and rainfall conditions can be monitored in real time.

[0044] 2. Combine with the monitoring data analysis to make a preliminary judgment on the harm degree of road ice conditions.

[0045] 3. Improve the traffic safety of driving vehicles: warning of road ice conditions ahead, environmental conditions, road closure warning, etc.

[0046] 4. It can adjust and lock the angle of the photovoltaic panel to improve the power generation efficiency of the photovoltaic panel and achieve self-power supply.

[0047] In summary, the beneficial effects of the present utility model are as follows: This device has the characteristics of simple structure, strong field adaptability, reliable monitoring results, and information security, making up for the deficiencies of the conventional judgment technology of traditional hidden ice monitoring technology. The monitoring equipment is more automated and intelligent, and can more comprehensively and accurately monitor the hidden ice conditions of the road.
