Description

Technical Field

[0001] This utility model relates to the field of high voltage switchgear technology, and more specifically, to a high voltage switchgear with a line management mechanism. Background Technology

[0002] High-voltage intermediate-voltage switchgear with line management mechanisms plays multiple important roles in power systems. Primarily through power distribution and transmission, as an indoor complete power distribution unit, it can receive and distribute 3.6~12kV network power. It is suitable for power plants, small and medium-sized generators, power receiving and transmission in secondary substations of power systems, and power distribution in industrial and mining enterprises and institutions.

[0003] Among the existing publicly available documents, patent publication number CN209374981U discloses a mine explosion-proof high-voltage distribution cabinet. This technology improves the safety of the distribution cabinet by simultaneously installing a protective device inside the cabinet, using insulating and flame-retardant materials such as ceramics for the protective device. A ventilation box for heat dissipation is also installed between the protective device and the cabinet to facilitate the exhaust of air from inside the distribution cabinet, promoting heat dissipation for electrical appliances and preventing dust from entering and causing cleaning difficulties or accidents. It also provides cooling for the inside of the distribution cabinet, further enhancing its safety. However, this patent has the following drawbacks.

[0004] When using a high-voltage intermediate switchgear, the wiring harnesses inside need to be organized and installed in designated locations. However, due to the large number of wiring harnesses, they need to be placed one by one into the organization position for fixing. This results in a low speed for organizing and fixing the high-voltage intermediate switchgear wiring. Therefore, a high-voltage intermediate switchgear with a wiring organization mechanism is needed. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a high-voltage intermediate switchgear with a line organizing mechanism, comprising a high-voltage intermediate switchgear shell, a support frame, and a limiting screw. The support frame is fixed to one side of the inner wall of the high-voltage intermediate switchgear shell, and the limiting screw is rotatably connected to the inner wall of the support frame. The outer wall of the limiting screw is provided with a positioning and organizing mechanism. The positioning and organizing mechanism includes a threaded sleeve block threaded onto the outer wall of the limiting screw. A concave pressure strip is fixedly connected to one side of the threaded sleeve block, and multiple extrusion strips are fixedly connected to one side of the inner wall of the concave pressure strip. A connecting slider is provided below the support frame, and the connecting slider is fixedly connected to the concave pressure strip. A sliding rod is slidably connected to the inner wall of the connecting slider, and an organizing strip is fixedly installed at one end of the sliding rod. The extrusion strip and the concave pressure strip are slidably connected to the organizing strip, and a limiting strip is provided on one side of the organizing strip.

[0006] Preferably, the outer wall of the threaded sleeve and the inner wall of the support frame are both smooth surfaces, and a rotating cap is provided at one end of the limiting screw. The vertical cross-sectional shape of the rotating cap is polygonal. The aligning strip and the limiting strip are both fixedly connected to the high-pressure central housing, and the vertical cross-sectional shape of the concave pressure strip is concave. An upper door is hinged to one side of the high-pressure central housing, and a lower door is provided below the upper door, with the lower door hinged to the high-pressure central housing.

[0007] In use, the tidied wire harness is placed in the gap between the tidier strip and the limiting strip. At the same time, the rotating cap is rotated, which drives the limiting screw to rotate. The threaded sleeve block drives the concave pressure strip to move to the right, and the concave pressure strip drives multiple extrusion strips to move to the right, quickly limiting and fixing the tidied wire harness in the gap between the tidier strip and the limiting strip, thus quickly fixing the tidied wire harness between the tidier strip and the limiting strip.

[0008] Preferably, a linkage frame is provided on one side of the limiting strip, and the linkage frame is fixedly connected to the high-pressure central housing. A vertical positioning component is installed inside the linkage frame. The vertical positioning component includes a linkage screw rotatably installed inside the linkage frame, and a vertical pressure bar is threadedly connected to the outer wall of the linkage screw. A rotating cap is fixedly installed at the top of the linkage screw. Two extrusion support bars are fixedly connected to one side of the vertical pressure bar. Two tidying line holes are opened at the bottom of the inner wall of the high-pressure central housing. The cross-sectional shape of the vertical pressure bar is T-shaped, and both the outer wall of the vertical pressure bar and the inner wall of the linkage frame are smooth surfaces. The cross-sectional shape of the extrusion support bar is rectangular, and the cross-sectional shape of the two tidying line holes is circular.

[0009] In use, the tidied wire harness is inserted into the tidied wire hole. The rotating cap drives the linkage screw to rotate, and the linkage screw causes the vertical pressure bar to move downward under the action of the thread transmission force. The extrusion support bar is pressed against the upper surface of the tidied wire harness, thereby vertically limiting and fixing the tidied wire harness to the bottom of the inner wall of the high-pressure intermediate shell.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model adopts a positioning and sorting mechanism, which places the sorted wire harness in the gap between the sorting strip and the limiting strip. At the same time, the rotating cap is rotated, which drives the limiting screw to rotate. The threaded sleeve block drives the concave pressure strip to move to the right, and the concave pressure strip drives multiple extrusion strips to move to the right, quickly fixing the sorted wire harness in the gap between the sorting strip and the limiting strip. The connecting slider will slide to the right along the outer wall of the slider rod, quickly fixing the sorted wire harness between the sorting strip and the limiting strip, greatly improving the speed of sorting and fixing high voltage switchgear lines.

[0012] 2. This utility model adopts a vertical positioning component. The tidied wire harness is inserted into the tidied wire hole. By rotating the rotating cap, the linkage screw causes the vertical pressure bar to move downward under the action of the thread transmission force, so as to vertically limit and fix the tidied wire harness to the bottom of the inner wall of the high-voltage intermediate shell, which greatly improves the vertical limiting and fixing efficiency.

[0019] 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 protection scope of the present utility model.

[0020] As attached Figure 1-5The diagram shows a high-voltage intermediate switchgear with a line arrangement mechanism. The high-voltage intermediate switchgear with the line arrangement mechanism is equipped with a positioning arrangement mechanism. The positioning arrangement mechanism enables the connecting slider 8 to slide to the right along the outer wall of the sliding rod 9, quickly fixing the arranged wire harness between the arrangement bar 10 and the limit bar 11, greatly improving the speed of arranging and fixing the high-voltage intermediate switchgear line. The specific structural configuration of the positioning arrangement mechanism is as follows.

[0021] In this embodiment, as shown in the appendix Figure 1-3 As shown, the support frame 2 is fixed to one side of the inner wall of the high-pressure intermediate shell 1, the limiting screw 3 is rotatably connected to the inner wall of the support frame 2, and the outer wall of the limiting screw 3 is provided with a positioning and sorting mechanism; the positioning and sorting mechanism includes a threaded sleeve 5 with threads set on the outer wall of the limiting screw 3, a concave pressure strip 6 is fixedly connected to one side of the threaded sleeve 5, and a plurality of extrusion strips 7 are fixedly connected to one side of the inner wall of the concave pressure strip 6.

[0022] A sliding block 8 is provided below the support frame 2, and the sliding block 8 is fixedly connected to the concave pressure strip 6. A sliding rod 9 is slidably connected to the inner wall of the sliding block 8. A sorting strip 10 is fixedly installed at one end of the sliding rod 9. The extrusion strip 7 and the concave pressure strip 6 are slidably connected to the sorting strip 10. A limiting strip 11 is provided on one side of the sorting strip 10.

[0023] In this embodiment, as shown in the appendix Figure 1 As shown, an upper door 12 is hinged to one side of the high-voltage central housing 1, and a lower door 13 is provided below the upper door 12. The lower door 13 is hinged to the high-voltage central housing 1 so that the upper door 12 and the lower door 13 can be separated and opened from the high-voltage central housing 1 by rotating the upper door 12 and rotating the lower door 13.

[0024] In this embodiment, the high-voltage intermediate switchgear with a line arrangement mechanism is used by rotating the upper door 12 and the lower door 13, thus separating the upper door 12 and the lower door 13 from the high-voltage intermediate switchgear housing 1. The arranged wire harness is then placed in the gap between the arrangement strip 10 and the limiting strip 11. Simultaneously, rotating the rotating cap 4 causes the limiting screw 3 to rotate. The limiting screw 3 causes the threaded sleeve block 5 to move to the right under the action of the thread transmission force. This causes the threaded sleeve block 5 to move the concave pressure strip 6 to the right, which in turn causes multiple extrusion strips 7 to move to the right. The extrusion strips 7 and the concave pressure strip 6 can move to the right along the side of the arrangement strip 10, quickly fixing the arranged wire harness in the gap between the arrangement strip 10 and the limiting strip 11. Simultaneously, the rightward movement of the concave pressure strip 6 causes the connecting slider 8 to move to the right, guiding it to slide to the right along the outer wall of the sliding rod 9. This quickly fixes the arranged wire harness between the arrangement strip 10 and the limiting strip 11.

[0025] In this embodiment, as shown in the appendix Figure 4-5As shown, a linkage frame 14 is provided on one side of the limiting strip 11. The linkage frame 14 is fixedly connected to the high-pressure central housing 1. A vertical positioning component is installed inside the linkage frame 14. The vertical positioning component includes a linkage screw 15 rotatably installed inside the linkage frame 14, and a vertical pressure strip 17 is threadedly connected to the outer wall of the linkage screw 15. A rotating cap 16 is fixedly installed at the top of the linkage screw 15. Two extrusion support strips 18 are fixedly connected to one side of the vertical pressure strip 17. Two tidying line holes 19 are opened at the bottom of the inner wall of the high-pressure central housing 1. The cross-sectional shape of the vertical pressure strip 17 is T-shaped. The outer wall of the vertical pressure strip 17 and the inner wall of the linkage frame 14 are both smooth surfaces. The cross-sectional shape of the extrusion support strip 18 is rectangular, and the cross-sectional shape of the two tidying line holes 19 is circular.

[0026] In this embodiment, the tidied wire harness is inserted into the tidied wire hole 19. By rotating the rotating cap 16, the rotating cap 16 drives the linkage screw 15 to rotate. The linkage screw 15 causes the vertical pressure bar 17 to move downward under the action of the thread transmission force. In this way, the vertical pressure bar 17 drives the two extrusion support bars 18 to move downward. The extrusion support bars 18 press against the upper surface of the tidied wire harness, thereby vertically limiting and fixing the tidied wire harness to the bottom of the inner wall of the high-pressure intermediate shell 1.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
