AI Technical Summary
In cold weather, the guide rails with sliding contact lines are prone to deform or hardening, affecting the conductivity, and the freezing of the guide rails will hinder the sliding of the brush case frame and may even cause damage.
A touch-slip line sheath insulation mechanism is designed, including sheath, guide rails and heating components. The sheath is equipped with a through groove, and guide rails and heating components (such as long strips of electric heating tubes) are installed in the through groove. The heating components maintain the internal temperature of the through groove by dissipating heat to prevent the rails from deforming and icing.
The internal temperature of the through-channel is maintained through the heating assembly, preventing the guide rail from deforming and icing, ensuring stable conductivity of the guide rail, and the brush case frame can still slide steadily in cold weather, reducing the failure or damage of the receiver caused by intermittent power transmission.

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0018] A contact-sliding wire sheath heat preservation mechanism comprises a sheath 1, a guide rail 2 and a heating component, wherein the sheath 1 is provided with a through groove 11 which penetrates through the sheath 1 in its length direction, and a through opening 12 which is connected to the through groove 11 and allows a brush housing frame to enter is provided on one side of the sheath 1, the cross section of the through groove 11 is rectangular, and the sheath 1 is provided with first installation groove bodies 13 extending along its length direction at positions corresponding to the four corner surfaces of the inner wall of the through groove 11, and the four first installation groove bodies 13 are all open at the ends and closed at the surrounding sides, and the heating component comprises a long strip electric heating tube 3, and an electric heating tube 3 is installed inside each first installation groove body 13, and the electric heating tube 3 is inserted into the first installation groove body 13 through the port of the first installation groove body 13. The sleeve 1 is installed in the installation groove 13, and the three inner wall surfaces of the through groove 11 away from the through opening 12 are all provided with second installation grooves 14. The second installation grooves 14 extend along the length direction of the sleeve 1. There is at least one second installation groove 14 provided on each inner wall surface, and specifically, a second installation groove 14 is provided on the inner wall surface on the side where the through opening 12 is located, and two second installation grooves 14 are provided on the other two opposite inner wall surfaces. The end of each second installation groove 14 and one side of the peripheral wall are both opened, and a guide rail 2 is installed inside each second installation groove 14, and the guide rail 2 passes through the second installation groove 14 from the port The guide rail 2 is installed in the slot body 14, and the electric heating tube 3 is electrically connected to the external power supply. In cold weather, the electric heating tube 3 generates heat to increase the temperature inside the slot 11 in the sheath 1 and keep the inside of the slot 11 in a suitable range, so that the guide rail 2 is not easy to deform or harden due to low temperature, which is conducive to maintaining the conductive performance of the guide rail 2, so that the guide rail 2 can stably supply power to the electric receiver. At the same time, the guide rail 2 is not easy to freeze, so that the brush housing frame can still slide stably in cold weather. The long strip electric heating tube 3 is convenient for heat dissipation to various positions in the extension direction of the slot 11, so that all parts of the guide rail 2 along its length direction can be heated to drive away the cold. The four electric heating tubes 3 generate heat at the same time and dissipate to There is more heat in the slot 11, which is suitable for colder weather. The number of operating electric heating tubes 3 is set according to the outside temperature. When the outside temperature is low, multiple electric heating tubes 3 are turned on at the same time to generate heat. When the outside temperature is low, turning on one or two electric heating tubes 3 can maintain the slot 11 in a more suitable temperature range. There are multiple guide rails 2 and they are distributed on the three inner wall surfaces of the slot 11 away from the side of the through opening 12, which support the sliding of the brush housing frame. The support effect is better, the sliding of the brush housing frame is more stable, and power is transmitted by multiple guide rails 2, so the receiver is more stably powered, reducing the situation where the receiver fails or even is damaged due to intermittent power transmission.
[0019] Furthermore, the second mounting slot 14 is formed with a bending portion 141 bent inwardly and pressed against the rail on both sides of the peripheral wall opening. The bending portion 141 presses the guide rail 2, and the guide rail 2 is relatively stably confined in the second mounting slot 14. When the brush housing frame slides along the length direction of the guide rail 2, the guide rail 2 is not easy to shake or deviate, so that the brush housing frame slides stably and the conductive effect is better.
[0020] Furthermore, each guide rail 2 is recessed with a slide groove 21 extending along its length direction, and the slide groove 21 faces the opening position of the peripheral wall of the second mounting slot body 14. The brushes on the brush housing are in contact with the guide rail 2 in the slide groove 21. Limited by the slide groove 21, they slide stably along the length direction of the guide rail 2 and are not easy to fall off the guide rail 2, further reducing the situation where the power transmission is intermittent due to the brush not contacting the guide rail 2, resulting in failure or even damage of the receiver.
