[0029] In order to solve the technical problems in the background art, as Figures 1-5 shown, the present application provides a technical solution: a de-icing device for railway catenary, characterized as follows

[0030] The fixed seat 1 is the base of the whole deicing device, which is used to fix the device at the corresponding position of the railway overhead contact system. The mounting plate 2 is arranged on the fixed seat 1, which is used to support and install other components. A plurality of mounting holes 3 are arranged on the mounting plate 2, which are used to pass through the first rotating shaft 4, the transmission shaft 8 and the second rotating shaft 11 to realize the fixation and rotation of the components. The first rotating shaft 4 passes through the mounting hole 3, one end of which is connected with the roller 5 and the other end of which is provided with the transmission gear 6. The transmission gear 6 is connected with the motor 7, and the motor 7 is fixed on the fixed seat 1. The motor 7 drives the first rotating shaft 4 to rotate, thereby driving the rotation of the roller 5 and the transmission gear 6. The motor 7 is the power source of the device, which can be electric or pneumatic. The motor 7 drives the first rotating shaft 4 to rotate through the transmission gear 6. The transmission shaft 8 is arranged on the mounting plate 2, and the driven gear 9 and the first belt pulley 10 are sleeved on the shaft. The driven gear 9 is engaged with the transmission gear 6 to realize the transmission of power; and then the power is transmitted from the transmission gear 6 to the first belt pulley 10 through the belt transmission. The first belt pulley 10 rotates with the transmission shaft 8, is connected with the second belt pulley 13 through the belt, and realizes the transmission of power. The second rotating shaft 11 passes through the mounting hole 3, one end of which is connected with the rolling brush 12 and the other end of which is provided with the second belt pulley 13. The second belt pulley 13 is driven to rotate by the first belt pulley 10 through the belt transmission. The rolling brush 12 is the part directly contacting with the overhead contact system pipeline, which is used to remove the ice layer on the pipeline. The rolling brush 12 is made of wear-resistant material to adapt to the harsh deicing environment. The material receiving groove 14 is arranged on the fixed seat 1 and located at the bottom of the rolling brush 12 and the roller 5, which is used to collect the ice blocks and debris falling off during the deicing process. The guide slope 15 is fixed on the side wall of the material receiving groove 14 and forms a clamping with the roller 5 to the overhead contact system pipeline, so as to ensure the close contact between the deicing device and the overhead contact system.

[0031] In use, the pipeline is clamped between the guide slope 15 and the roller 5. After the motor 7 is started, the first rotating shaft 4 and the second rotating shaft 11 are driven to rotate through the engagement of the transmission gear 6 and the driven gear 9 and the belt transmission. The roller 5 and the rolling brush 12 rotate, the roller 5 and the guide slope 15 clamp the pipeline to run forward, and the rolling brush 12 and the guide slope 15 deice the passing pipeline. The removed ice and debris fall into the material receiving groove 14 through the guide slope 15, which is convenient for subsequent cleaning work.

[0032] It should be pointed out that in order to ensure that the first rotating shaft 4 and the second rotating shaft 11 can rotate smoothly and efficiently, the bearing seat is arranged on the mounting plate 2. The bearing seat is used to fix the bearings to ensure the stability of the first rotating shaft 4 and the second rotating shaft 11 and reduce friction. Bearings are installed in the bearing seat, which can be ball bearings, roller bearings or other types of bearings. The bearings allow the rotating shafts to rotate flexibly between the fixed seat 1 and the mounting plate 2 while bearing the force transmitted by the motor 7. The two ends of the first rotating shaft 4 and the second rotating shaft 11 pass through the mounting hole 3 and are connected with the mounting plate 2 through the bearing seat.

[0033] Further, on both sides of the receiving trough 14, there are guide slopes 15. The design of these slopes is to guide the catenary wire pipeline to enter the working area of the deicing device correctly and ensure good contact between the pipeline and the rolling brush 12. The guide slopes 15 can be inclined planes or curved surfaces, one of which ensures that the pipeline can be smoothly guided to the rolling brush 12. The guide slopes 15 direct the catenary wire pipeline to the rolling brush 12, so that it maintains close contact with the rolling brush 12. In this way, when the rolling brush 12 rotates, it can effectively remove the ice layer on the pipeline. The receiving trough 14 is an open container, and its bottom and two side walls are strong enough to support the weight of the guide slopes 15 and withstand the impact force that may occur during deicing.

[0034] It should be noted that the diameter of the rolling brush 12 is designed to be smaller than the diameter of the roller 5, which helps to optimize the working performance of the deicing device. Since the rolling brush 12 directly contacts the catenary wire pipeline, a smaller diameter can prevent it from interfering with the roller 5, allowing it to better adapt to the profile and irregularities of the catenary wire pipeline. The smaller diameter of the rolling brush 12 results in greater linear pressure when it contacts the catenary wire pipeline at the same linear speed, which helps to improve deicing efficiency, as greater pressure can more effectively break up and remove ice layers.

[0035] It should be noted that the guide slopes 15 are provided with a rack 16, which is a long strip-shaped component with a series of teeth on its surface. The main function is to enhance the snow removal effect by allowing the catenary wire pipeline to contact the uneven surface.

[0036] It should be noted that the adjustment groove 17 is provided on the mounting plate 2 and is in the shape of a long strip, which is used to accommodate the shaft of the tensioning wheel 18 and allows the tensioning wheel 18 to slide and adjust within the groove. The design of the adjustment groove 17 allows the tensioning wheel 18 to move within a certain range to adjust the tension of the belt. The main function of the adjustment groove 17 is to provide an adjustable path for the tensioning wheel 18 to slide freely inside, thereby adjusting the tension of the belt. The tensioning wheel 18 is a wheel that can slide within the adjustment groove 17, with its shaft located within the adjustment groove 17. The tensioning wheel 18 is usually equipped with bearings to ensure smooth sliding within the groove and reduce friction. The main function of the tensioning wheel 18 is to adjust the tension of the belt. By moving the tensioning wheel 18 within the adjustment groove 17, the tension of the belt can be changed to ensure that there is appropriate contact pressure between the belt and the first pulley 10 and the second pulley 13, preventing the belt from slipping or excessive wear. During the operation of the deicing device, if the belt becomes loose or too tight, the tension of the belt can be adjusted by moving the tensioning wheel 18.

[0037] Notably, the discharge slot 19 is a through-going, elongated or rectangular slot provided at the bottom of the collection slot 14. This design allows for the continuous or batch removal of collected ice chips and other debris from the collection slot 14. The primary function of the discharge slot 19 is to provide an exit for the ice chips and slush collected in the collection slot 14. The through-going slot design allows for easy removal of waste material generated during the de-icing process.

[0038] While embodiments of the application have been shown and described, it is to be understood that the application is not limited to the details of the embodiments described, since numerous changes, modifications, substitutions and alterations can be made thereto without departing from the spirit and scope of the application as defined by the appended claims and their equivalents.
