The invention discloses a fan blade gas heat deicing system which comprises a heater and an air blower which are installed in a blade, an air inlet of the heater is connected with an air outlet of the air blower, an air outlet of the heater is communicated with an air inlet of an air guide pipe, an air outlet of the air guide pipe points to the blade tip direction, and a hard air pipe is adopted at the front end of the air guide pipe. The rear end of the air guide pipe is provided with a soft air pipe, an air inlet of the hard air pipe is communicated with an air outlet of the heater, an air outlet of the hard air pipe is communicated with an air inlet of the soft air pipe, the soft air pipe is arranged in a blade front edge cavity, a plurality of air guide holes are formed in the position, facing the blade front edge, of the soft air pipe, and when no hot air exists, the air guide holes are communicated with the hard air pipe. And when hot air exists, the flexible air pipe is stretched to be close to the blade tip or the blocked position of the blade tip. The air guide pipe can extend to the blade tip, the deicing effect of the blade tip is enhanced, a new hot air backflow channel can be constructed in the blade blocked by the blade tip, and the air heat deicing effect is achieved.

The invention provides a fan blade partition heating and deicing control method. The fan blade partition heating and deicing control method comprises the following steps that S1, a fan blade is divided into N heating areas from the front end of the blade to the root of the blade; the length from the front end to the root heating area forms an arithmetic progression; s2, arranging an electric heating strip in each heating area; s3, parameters of the environment where the fan blade is located are obtained, and the driving current for heating and deicing is determined according to the environment parameters of the fan blade; s4, controlling the electric heating strip to work according to the driving current; according to the method, the N regions in the arithmetic progression are formed according to the length of the fan blade from the end part to the root part, and then the layout modes of the heating strips in all the regions are different, so that the fan blade is heated in different ways, and the deicing loss can be prevented from being increased while the deicing effect is effectively ensured.

The invention relates to the technical field of train electricity taking, in particular to an urban rail vehicle combined collector shoe sliding plate which comprises an assembly bracket, and a lubricating component and a deicing component are arranged at the upper end of the assembly bracket; the deicing component comprises an assembling unit and a deicing unit, and the assembling unit and the deicing unit are fixedly installed on the two sides of the lubricating component through connecting screws. The combined collector shoe sliding plate of the urban rail vehicle is simple in structural form, easy to implement, capable of being efficiently produced on a large scale, high in deicing efficiency and friendly to the environment and users; the deicing groove is formed in the side wall of the deicing unit, and the lateral separation mechanism controlled by the semi-exposed driving impeller is movably assembled in the deicing groove, so that lateral deicing is facilitated, and the deicing effect is guaranteed; the semi-exposed driving impeller is driven through wind pressure generated in the running process of the train, additional kinetic energy is not needed, and operation is more convenient.

The invention relates to the technical field of overhead ground wire deicing, in particular to a ground wire deicing device. An open wire passing channel is formed in the bottom of the framework, the icebreaking mechanism is installed on the framework, a walking cavity only allowing a ground wire to penetrate through is formed in the upper portion of the wire passing channel, and an initial deicing cavity allowing the ground wire and ice to enter is formed in the lower portion of the wire passing channel; a walking mechanism used for enabling the deicing device to move on the ground wire is installed at the walking cavity, a clamping mechanism and a crawling mechanism are further installed on the framework, the clamping mechanism comprises two second clamping plates, the crawling mechanism comprises two first clamping plates, and the two second clamping plates and the two first clamping plates are symmetrically distributed on the two sides of a channel where the initial deicing cavity is located. And open clamping areas are formed between the two second clamping plates and between the two first clamping plates. According to the invention, the ice on the initial section of the ground wire can be processed without manual work or with the help of other ice breaking equipment, and the use convenience of the deicing device is improved.
