A road surface deicing device is characterized by comprising a deicing blade 1, a damping spring2, a locating rod 3, a connecting rod 4, a crankshaft connecting rod 5, a power device 6 and a support 7. The deicing blade 1 is connected with the connecting rod 4 together through the locating rod 3 and the damping spring 2. The crankshaft connecting rod 5 is connected with the power device 6. Due to the fact that ice has the feature of being easy to break, a crankshaft drives the deicing blade to move up and down, and therefore the deicing purpose is achieved.

The invention relates to the technical field of road cleaning, and discloses a pothole road deicing device which comprises a roller shaft, the roller shaft is hollow, the diameter of the inner wall of the roller shaft is gradually increased from the two ends to the middle, deicing cones are fixedly installed on the outer wall of the roller shaft, the two ends of the roller shaft are rotationally connected with push handles respectively, a circular connecting groove is formed in the upper end of the arc of the roller shaft, and a deicing frame is arranged between the inner walls of the two ends of the connecting groove. Rotation is achieved through the roller shaft, balance weight balls in the roller shaft impact the inner wall of the roller shaft under the action of gravity, an ice layer is thus cracked, soil on the pothole road is prevented from being shoveled and floated, and the original pothole ground is prevented from being more bumpy; the ice layer is not attached to the ground, and the deicing purpose is achieved; and in the collision process of the balance weight balls, the tip ends of the cones are jacked and thus more easily inserted into the ice layer, a better tearing effect is achieved, and the ice layer is better cracked.

In order to overcome the defects existing in a conventional deicing technique for airplanes, the invention provides a peelable thin-film type deicing method for the airplanes. The peelable thin-film type deicing method comprises the following step of pasting and covering a layer or layers of thin films which can be peeled due to reduced viscidity after being electrically heated, at positions wherein icing is easy to occur on a shell of an airplane, wherein the thin films along with icing on the thin films can be peeled together, so that the effect of deicing is achieved. The thin films are designed into being spliced, an impression or a cutting line, which is easy to tear, can also be arranged on a large thin film, and viscose of which the viscidity is easy to reduce after being heated is selected as glue for pasting and covering the thin films. Electric heating layers are arranged between the thin films and an airplane body and between the thin films, and are electrically connected with a heating power supply. When a temperature sensor or an inductor induces that ice is formed on the airplane, the heating power supply is switched on, the heating layers are uniformly heated, and the heated heating layers conduct heat to the glue of the thin films, so that the viscidity of the glue is reduced, and the thin films are torn along grid lines and are peeled off along with icing layers on the thin films; and therefore, the purpose of deicing for the airplanes is achieved.
