Description

Technical Field

[0001] This utility model relates to the field of line distribution devices, specifically a line distribution device for thermal control equipment in a thermal power plant. Background Technology

[0002] The thermal control equipment distribution device in a thermal power plant is used to separate, organize, and fix multiple sets of lines in the thermal control equipment. It classifies and organizes the complex and numerous lines in the thermal control equipment, so that the lines are distributed in an orderly manner, avoiding confusion and tangling, and facilitating installation, commissioning, and maintenance.

[0003] Chinese Patent No. CN202322309391.2 discloses a branching device for thermal control equipment in a thermal power plant, including a branching assembly. The branching assembly includes a mounting base, two rollers, a guide groove, two limiting rods, a locking sleeve, two sliding seats, a wire groove, a tension spring, four sliders, two guide rods, and two sliding channels. The adjacent surfaces of the two sliding seats are symmetrically fixedly connected to both sides of the mounting base. The guide groove is equidistantly opened on the front surface of the mounting base. The two sliding channels are symmetrically opened on both sides of the inner wall of the guide groove. The two ends of the two rollers are symmetrically rotatably connected to the adjacent surfaces of the four sliders. The four sliders are symmetrically slidably connected to the inner sidewalls of the two sliding channels. The two ends of the two guide rods are symmetrically fixedly connected to the inner top wall and inner bottom wall of the sliding channels. The tension spring is sleeved on the outer sidewall of the guide rod. The locking sleeve is threadedly connected to the outer sidewall of the limiting rod. The wire groove is opened on the outer sidewall of the roller.

[0004] As can be seen from the above, by setting a tension spring, wires of different diameters can be positioned and guided, increasing the applicability. However, this case still has the following shortcomings:

[0005] Firstly, the fixed cable guiding structure makes it impossible to flexibly adjust the path according to the number and specifications of cables, resulting in low cable splitting efficiency.

[0006] Secondly, the lack of effective anti-tangling measures makes cables prone to tangling and knotting when connected to junction boxes, affecting equipment maintenance and repair.

[0007] Third, the splitter has poor adaptability and cannot meet the splitting requirements of cables of different diameters and types. In addition, the rigid fixing method may damage the cable insulation layer.

[0008] Therefore, a branching device for thermal control equipment in thermal power plants is proposed to address the above problems. Utility Model Content

[0009] To address the shortcomings of existing technologies, such as chaotic cable management, easy tangling, and low cable splitting efficiency, this utility model proposes a cable splitting device for thermal control equipment in thermal power plants.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0032] Please see Figures 1-5 As shown, a branching device for thermal control equipment in a thermal power plant includes a main body 1. A guide device 2 and two anti-winding components 3 are provided on one side of the main body 1. The guide device 2 includes a fixed frame 21 installed on the top of the main body 1. A cylinder 22 is fixedly installed on one side of the fixed frame 21. A piston rod 23 is movably installed at the output end of the cylinder 22. One end of the piston rod 23 is hinged to two linkage rods 24. The other end of the linkage rods 24 is hinged to a telescopic component 28. The telescopic component 28 is formed by hinged first movable arm 25 and second movable arm 26 in sequence. A connecting shaft 27 is movably installed through the middle of the first movable arm 25 and the second movable arm 26.

[0033] During operation, after the cylinder 22 is started, the piston rod 23 extends or retracts, causing the linkage rod 24 to swing. The linkage rod 24 pushes the first movable arm 25 and the second movable arm 26 in the telescopic assembly 28 to rotate around the connecting shaft 27, thereby adjusting the extension angle of the telescopic assembly 28 and adjusting the position of the connecting roller 201 to adapt to the guiding requirements of different cables.

[0034] Furthermore, the guide device 2 also includes several connecting rollers 201, which are movably mounted on one end of the first movable arm 25 and the second movable arm 26 respectively. A movable slider 202 is fixedly mounted on one side of the back of the connecting roller 201.

[0035] During operation, the connecting roller 201 can rotate around its own axis to reduce friction during cable guidance; when the angle of the telescopic component 28 changes, the movable slider 202 slides in the movable groove 29 of the fixed frame 21 to ensure that the connecting roller 201 moves smoothly and to prevent the cable from getting tangled due to the shaking of the guiding structure.

[0036] Furthermore, the outer circumferential surface of the connecting roller 201 is provided with an anti-slip rubber layer, and the surface of the rubber layer is provided with a spiral groove.

[0037] During operation, the anti-slip rubber layer increases the friction of the contact surface, preventing the cable from slipping or deviating during the guiding process; the spiral cable trough can arrange the cables in an orderly manner, separating multiple cables along the direction of the trough and preventing the cables from getting tangled together.

[0038] Furthermore, the fixed frame 21 has several movable slots 29, and several movable sliders 202 are slidably installed through the movable slots 29; the cross-sectional shape of the movable slot 29 is T-shaped, and the movable sliders 202 are slidably engaged with the movable slot 29;

[0039] During operation, the T-shaped cross-section movable groove 29 prevents the movable slider 202 from falling off during sliding, while providing a stable guide trajectory for the movable slider 202 to ensure the movement accuracy of the connecting roller 201. When the cylinder 22 drives the telescopic component 28 to swing, the movable slider 202 slides in the movable groove 29 in a preset direction to avoid lateral displacement of the connecting roller 201 and ensure the stability of the cable guide path.

[0040] Furthermore, the anti-winding component 3 includes a mounting plate 31, on one side of which a plurality of connecting seats 32 are fixedly mounted, and on one side of each of the plurality of connecting seats 32 are respectively fixedly mounted a limiting plate 33. The cable is limited by the gap between the connecting seats 32 and the limiting plate 33. The mounting plate 31 is provided with a guide groove 34.

[0041] During operation, the cable passes through the gap between the connector 32 and the limiting plate 33. The limiting plate 33 prevents the cable from shifting laterally, while the guide groove 34 positions the cable longitudinally, ensuring that the cable is connected to the junction box 13 in the fixed compartment 11 along a preset path, thus avoiding cable crossing and tangling.

[0042] Furthermore, the gap between the limiting plate 33 and the connecting seat 32 is 0.5-2mm, and the inner edge of the limiting plate 33 is provided with a rounded corner structure.

[0043] During operation, the 0.5-2mm gap can accommodate cables of different diameters, preventing cables from becoming loose and avoiding compression of the cables due to insufficient gap; the rounded corner structure can prevent the cable insulation layer from being scratched by sharp edges, improving the cable protection effect.

[0044] Furthermore, the cross-section of the guide groove 34 is arc-shaped, and the inner wall of the guide groove 34 is provided with a wear-resistant coating.

[0045] During operation, the arc-shaped cross-section can guide the cable to turn smoothly, reducing cable damage caused by excessive bending angle; the wear-resistant coating can reduce the coefficient of friction between the cable and the groove wall, extend the service life of the guide groove 34, and at the same time prevent the cable from generating heat or wear due to friction. When the cable turns and enters the junction box 13, the arc-shaped guide groove 34 can keep the cable in a natural bend, reducing stress concentration.

[0046] Furthermore, the main body 1 includes a fixed compartment 11, a wire clip 12 is fixedly installed in the inner cavity of the fixed compartment 11, and multiple junction boxes 13 are fixedly installed in the inner cavity of the fixed compartment 11; the wire clip 12 is made of elastic metal material, and the clamping end of the wire clip 12 is provided with anti-slip ridges.

[0047] During operation, the flexible metal cable clip 12 can adapt to cables of different diameters through deformation, providing a stable clamping force; the anti-slip ridges increase the friction between the cable clip 12 and the cable, preventing the cable from loosening or falling off.

[0048] Furthermore, grooves are provided on both sides of the fixed compartment 11, and mounting plates 31 are fixedly installed through the grooves. A fixing frame 21 is fixedly installed on the top of the fixed compartment 11. A detachable protective cover is hinged to the front end of the fixed compartment 11, and a sealing strip is provided on the inner side of the protective cover.

[0049] During operation, the groove design makes the mounting plate 31 flush with the side wall of the fixing chamber 11, saving installation space and enhancing structural stability; the protective cover achieves dustproof and waterproof sealing through sealing strips, protecting the cables and junction boxes 13 inside the fixing chamber 11 from dust and moisture.

[0050] Furthermore, the bottom of the main body 1 is provided with a mounting base, and the mounting base has multiple bolt holes for fixing the branching device to the inner wall of the cabinet of the thermal control equipment in the thermal power plant.

[0051] During operation, the distribution device is fixed to the inner wall of the cabinet by bolts passing through the bolt holes to ensure that the device remains stable during equipment operation and to avoid structural displacement or cable loosening due to vibration.

[0052] Working principle: According to the cable routing requirements, the position and angle of the connecting roller 201 in the guide device 2 are adjusted by the cylinder 22 to form a cable guiding path. Then, the cable passes through the limiting plate 33 and the guide groove 34 of the anti-winding component 3 in sequence. The lateral limiting of the limiting plate 33 and the longitudinal guiding of the guide groove 34 are used for initial positioning. Finally, the cable enters the fixed compartment 11, is fixed by the elastic wire clip 12 and connected to the junction box 13 to complete the cable splitting operation. The adjustable structure of the guide device 2 can adapt to different cable layouts, the anti-winding component 3 prevents the cable from getting tangled, and the fixed compartment 11 realizes the orderly storage of the cable, thereby solving the problems of low efficiency and chaotic cable management of traditional cable splitting devices.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
