It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0028] like Figure 1 and Figure 2 As shown, this embodiment provides a sensor cable bracket, which includes a straight section 10 and two arc-shaped transition sections 20. The two arc-shaped transition sections 20 are respectively connected to the two ends of the straight section 10. The inner arc surface of each arc-shaped transition section 20 is at least partially provided with a wear-resistant layer. The straight section 10 and the arc-shaped transition section 20 are internally connected for threading cables, and the two ends of the cable can respectively extend to the outside of the two arc-shaped transition sections 20.

[0029] By providing a sensor cable bracket with a straight section 10 and an arc-shaped transition section 20, the cable can be passed through the straight section 10 and the arc-shaped transition section 20, thereby protecting the cable from damage; by providing the arc-shaped transition section 20 and a wear-resistant layer, the cable can be smoothly placed on the wear-resistant layer of the arc-shaped transition section 20 and bend along the arc-shaped transition section 20, thereby reducing the friction between the cable and the edge of the sensor cable bracket, effectively alleviating the wear of the cable, and ensuring the reliability and service life of the cable.

[0030] Specifically, the two arcuate transition sections 20 curve and extend toward either side of the straight section 10. The arcuate transition sections 20 curve into an arc shape, and the central angle θ corresponding to the arcuate transition sections 20 ranges from 10° to 45°. After the two arcuate transition sections 20 are bent into an arc shape, the central angle θ corresponding to the two arcuate transition sections 20 can be the same or different.

[0031] During actual use, the sensor cable bracket is installed as an independent unit above the volute of the gas turbine. The cable is passed through the sensor cable bracket. The two ends of the cable are respectively close to the two arc-shaped transition sections 20 and extend from the arc-shaped transition sections 20. One end of the cable is used to connect to the speed sensor located below the sensor cable bracket, and the other end of the cable is used to connect to the junction box located above the sensor cable bracket.

[0032] By setting two arc-shaped transition sections 20 to bend and extend toward both sides of the straight section 10, when the straight section 10 is placed horizontally, one arc-shaped transition section 20 bends upward and the other arc-shaped transition section 20 bends downward, and both ends of the cable can bend and transition along with the arc-shaped transition section 20. After the two ends of the cable are respectively connected to the speed sensor and the junction box, the cable will cling to the wear-resistant layer of the arc-shaped transition section 20, reducing the friction between the cable and the edge of the sensor cable bracket, effectively alleviating the wear of the cable, thereby meeting actual application needs.

[0033] The arc-shaped transition section 20 is curved into an arc shape, which can better adapt to the bending of the cable. It is understood that the length of the arc-shaped transition section 20 is appropriate and should not be too long or too short. Preferably, the arc-shaped transition section 20 is curved into an arc shape with a corresponding central angle θ of 15°; both arc-shaped transition sections 20 are curved into an arc shape; and the central angle θ corresponding to the two arc-shaped transition sections 20 is the same.

[0034] Furthermore, a wear-resistant layer is embedded within the arc-shaped transition section 20, with its surface exposed outside the arc-shaped transition section 20. The wear-resistant layer is made of tin foil. By embedding the wear-resistant layer within the arc-shaped transition section 20, a smooth transition is achieved between the wear-resistant layer surface and the inner curved surface of the arc-shaped transition section 20. The wear-resistant layer is exposed from the surface of the arc-shaped transition section 20 for contact with the outer surface of the cable, thereby reducing the wear intensity of the cable. A groove can be provided in the arc-shaped transition section 20, and the wear-resistant layer can be embedded within the groove. In other embodiments, when the wear-resistant layer is thin, the wear-resistant layer can be placed flat against the inner curved surface of the arc-shaped transition section 20.

[0035] In this embodiment, a wear-resistant layer is provided on the inner arc surface of each arc-shaped transition section 20. In other embodiments, a wear-resistant layer may also be provided on both the straight section 10 and the arc-shaped transition section 20.

[0036] By using tin foil material to make the wear-resistant layer, the tin foil material has wear resistance and can maintain stability and durability during use. The tin foil material also has good heat insulation properties. The heat insulation effect of the tin foil material is due to its own special structure. The tin foil material can significantly reduce the transfer of heat and can prevent high temperature heat from being transferred to the cable even in a high temperature environment. It can not only ensure the normal use safety of the cable, but also extend the service life of the cable.

[0037] Optionally, each arcuate transition section 20 has at least two juxtaposed receiving locations, each of which is provided with a wear-resistant layer of varying thickness; the wear-resistant layer has a curved surface. By providing juxtaposed receiving locations, when two cables are routed through the sensor cable bracket, each cable can independently contact the wear-resistant layer of each receiving location. Depending on the material of the cables, the wear-resistant layer of each receiving location can be configured to a different thickness, thereby providing wear resistance for cables of varying materials.

[0038] In this embodiment, three accommodating positions are provided; three cables are threaded through the sensor cable holder: a power cable, a signal cable, and an output cable. The power cable is used for power supply, the output cable is used for outputting signals, and the signal cable is used for receiving signals. In other embodiments, two or more cables may be threaded through the sensor cable holder. The corresponding accommodating positions can be provided based on the number and size of cables in actual application, and the size of the sensor cable holder can be adaptively adjusted.

[0039] Optionally, an isolation protrusion is provided within the arcuate transition section 20 to separate two adjacent cables. To prevent contact or entanglement between the two cables, the isolation protrusion is provided within the arcuate transition section 20. The isolation protrusion can separate the two adjacent cables and reduce friction between the cables. It is understood that the isolation protrusion and the arcuate transition section 20 can be an integrated structure. For example, the arcuate transition section 20 can include two isolation protrusions spaced apart, thereby dividing the interior of the arcuate transition section 20 into three accommodating spaces for three cables. The isolation protrusion can be cylindrical to minimize the contact area between the isolation protrusion and the cables.

[0040] In this embodiment, the straight section 10 and the arc-shaped transition section 20 are an integrated structure and are made of metal; the straight section 10 is a hollow square tube or rectangular tube; the two ends of the arc-shaped transition section 20 are adapted to the ends of the straight section 10.

[0041] Optionally, the straight section 10 and the curved transition section 20 are detachably connected. By providing a detachable connection between the straight section 10 and the curved transition section 20, suitable straight sections 10 and curved transition sections 20 can be combined according to the actual cable length, thereby improving applicability. It is understood that the straight section 10 and the curved transition section 20 can be detachably connected by a threaded connection.

[0042] Optionally, the arcuate transition section 20 is rotatably connected to the straight section 10. By arranging the arcuate transition section 20 to be rotatably connected to the straight section 10, the arcuate transition section 20 can rotate relative to the straight section 10, thereby adjusting the bending direction of the arcuate transition section 20 to meet the cable connection requirements in different scenarios. It is understood that the ends of the straight section 10 and the arcuate transition section 20 can be configured as circular tubes, with the arcuate transition section 20 rotatably connected to the straight section 10. Alternatively, an auxiliary connecting tube can be provided, through which the arcuate transition section 20 and the straight section 10 are rotatably connected.

[0043] The sensor cable bracket provided in this embodiment adopts a structure that is straight in the middle and curved at both ends, and a wear-resistant layer is added in the arc-shaped transition section 20, which can not only protect the supporting cable but also adapt to the bending curvature of the cable. The cable can be laid along the curvature of the arc-shaped transition section 20 to facilitate the connection of the cable end with other components, preventing the edge of the sensor cable bracket from seriously wearing the cable or even causing the cable to break, thereby effectively improving the reliability and service life of the cable.

[0044] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
