DETAILED DESCRIPTION

[0032] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0033] Reference Figure 1 and Figure 3 The present invention provides an embodiment of a power distribution network planning device based on a power distribution network frame, comprising a support column 1, which is made of high-strength steel and serves to provide support for the entire power distribution network planning device. It is the main structure of the entire device. The outer wall of the support column 1 has multiple mounting holes 6 arranged in an array. The mounting holes 6 are slotted holes machined inside the support column 1 and serve to provide position selection for the installation of support components, making it convenient to adjust the installation position of the support components according to actual operation requirements. The outer wall of the support column 1 is provided with symmetrical support components. Each support component is fixedly connected to a connecting plate 5, which is made of steel plate and serves to connect the support components and the support column 1, playing a transition and fixing role. A fixing component is provided between the connecting plate 5 and the mounting holes 6.

[0034] The fixing assembly includes an outer column 7, which is a hollow tube made of stainless steel and serves for positioning and support. The outer wall of the outer column 7 is slidably connected to the connecting plate 5 and the mounting hole 6. Circularly distributed ball bearings 8, made of hard alloy steel, are slidably connected inside the outer column 7. Their function is to roll into the grooves inside the mounting hole 6 during the fixing process, thereby locking the outer column 7 to the mounting hole 6. A limit plate 9 is fixedly connected to the inner wall of the outer column 7, which limits the displacement range of the limit block 13 and assists in locking the position of the inner column 10. An inner column 10, made of the same material as the outer column 7, is slidably connected inside the outer column 7. Its function is... The position of the ball bearing 8 is controlled by its own displacement. A limiting groove 11 is formed at the bottom of the inner column 10. The limiting groove 11 is a groove formed at the bottom of the inner column 10 by machining. Its function is to accommodate the ball bearing 8 and control the rolling direction of the ball bearing 8 during its own displacement. A linkage column 12 is fixedly connected to the top of the limiting groove 11. A rotating auxiliary handle is provided at the top of the linkage column 12 for easy operation by construction personnel. Its function is to transmit the force applied by the worker, driving the inner column 10 and the limiting groove 11 to move. A circumferentially distributed limiting block 13 is fixedly connected to the outer wall of the linkage column 12. The limiting block 13 is generally made of stainless steel and its function is to connect with the limiting plate 9. In conjunction with the linkage column 12, a return spring 14 is installed at the bottom of the linkage column 12 to lock the position of the inner column 10. The function of the return spring 14 is to store elastic potential energy when the linkage column 12 is pressed and compressed, and to release the elastic potential energy when the linkage column 12 is released, pushing the linkage column 12 to return to its original position and assisting in locking the position of the inner column 10. One end of the return spring 14 is fixedly connected to the inside of the outer column 7, and the other end of the return spring 14 is slidably connected to the bottom of the linkage column 12. A base plate 2 is fixedly connected to the bottom of the support column 1, which increases the contact area between the support column 1 and the ground and improves the stability of the device. The base plate 2 has multiple fixing holes 3 inside. The support components are arranged in an array to facilitate the use of bolts and other fasteners to fix the support column 1 to the ground. The support components include a bracket 4, which is made of channel steel. Its function is to provide support and an installation platform for power distribution network related equipment. The side wall of the bracket 4 is fixedly connected to the center of the side wall of the connecting plate 5 by welding. Multiple base blocks 15 are provided at the top and bottom of the bracket 4. The base blocks 15 are made of aluminum alloy, which has the characteristics of light weight and high strength. Their function is to provide a support base for the connecting rod 17 and, together with the slider 18, to fix the cable. The base blocks 15 are arranged in an array, and the bottom of each base block 15 is fixedly connected to the outer wall of the bracket 4.

[0035] Specifically, when using this power distribution network planning device, the staff first determines the required height and angle of the bracket 4 according to the specific requirements of the power distribution network plan, and then selects a suitable mounting hole 6. When installing the bracket 4, the staff first aligns the hole on the connecting plate 5 on one side of the bracket 4 with the selected mounting hole 6 on the support column 1. Then, the construction worker holds the outer column 7, aligns one end of the outer column 7 with the hole after the connecting plate 5 and the mounting hole 6 are aligned, and inserts it into the hole. When the bottom of the outer column 7 is completely inserted into the interior of the mounting hole 6, the construction worker presses down on the linkage column 12. The displacement of the linkage column 12 causes the limiting block 13 on its outer wall to move downward as well. Driven by the linkage column 12, the limiting block 13 moves from above the limiting plate 9, through the reserved hole on the limiting plate 9, to below the limiting plate 9. During the downward displacement of the linkage column 12, the return spring 14 at its bottom is compressed, and the elastic potential energy continuously increases. At the same time, the inner column 10 and the linkage column 12 are fixedly connected at the top through the limiting groove 11. When the linkage column 12 moves, the inner column 10 moves synchronously, and the limiting groove 11 at its bottom also moves downward. The ball bearing 8, which was originally inside the limiting groove 11, rolls from inside the limiting groove 11 into the groove inside the mounting hole 6 under the action of the inner wall of the limiting groove 11 as the limiting groove 11 moves downward. After the ball bearing 8 rolls to the appropriate position in the groove inside the mounting hole 6, it locks the mounting hole 6, thus locking the outer column 7 to the mounting hole 6. Then, the construction personnel rotate the linkage column 12, and the rotation of the linkage column 12... The movable limit block 13 is located below the limit plate 9. As the linkage column 12 rotates, the construction personnel release the linkage column 12, and the return spring 14 releases its elastic potential energy, pushing the linkage column 12 to move upward. Since the limit block 13 forms a locking structure with the limit plate 9 after rotation, the limit block 13 is stuck below the limit plate 9 and cannot be reset. This completes the limitation of the current position of the inner column 10. The inner column 10 remains in the current position, so that the ball 8 is stably stuck inside the mounting hole 6, thereby achieving the effect of quickly fixing the bracket 4.

[0036] Reference Figure 4Connecting rods 17 are fixedly connected to the top left and right sides of the base block 15. The connecting rods 17 are typically made of stainless steel tubing and serve to guide the sliding of the slider 18. A fixing block 16 is fixedly connected to the top of each connecting rod 17. The fixing block 16 is made of the same material as the base block 15. The fixing block 16 provides support and installation position for the threaded rod 20, and through its internal threads, it engages with the threaded rod 20 to achieve rotation and displacement conversion. The threaded rod 20 is slidably connected to the center of the fixing block 16. The threaded rod 20 has threads machined on its surface, which convert the rotation of the handle 21 into linear displacement, thereby driving the slider 18 to move up and down. The top of the threaded rod 20 is fixedly connected to... There is a handle 21, which is made of plastic and has an anti-slip surface to facilitate the rotation of the threaded rod 20 by construction personnel. The bottom of the threaded rod 20 is rotatably connected to a slider 18, which slides up and down along the connecting rod 17 under the drive of the threaded rod 20 to clamp and release the cable. The slider 18 is slidably connected to the outer wall of the connecting rod 17 on both the left and right sides. Anti-slip textures 19 are formed inside the slider 18 and the base block 15. The anti-slip textures 19 are textures formed on the inner surface of the slider 18 and the base block 15 by mechanical processing. The anti-slip textures 19 are used to increase the friction between the slider 18 and the base block 15 and the cable to prevent the cable from loosening or sliding during the fixing process.

[0037] Specifically, after fixing the position of bracket 4, the worker holds one end of the cable with one hand and guides the cable through the gap between base block 15 and fixing block 16 with the other hand, positioning the cable in a suitable position to prepare for subsequent fixing operations. Then, the worker holds handle 21 and applies rotational force clockwise. The rotation of handle 21 causes the threaded rod 20, which is fixedly connected to it, to rotate synchronously. During rotation, the threads on the outer wall of threaded rod 20 mesh with the threads on the inner wall of fixing block 16. Under the helical transmission of the threads, the circumferential rotation of threaded rod 20 is converted into a axial rotation along its own axis. The threaded rod 20 is connected to the slider 18 via a rotating connection structure. When the threaded rod 20 moves downward, it drives the slider 18 to move downward as well. Guided by the connecting rod 17, the slider 18 slides downward along the connecting rod 17. As the slider 18 moves downward, the bottom of the slider 18 gradually contacts the surface of the cable and applies pressure to the cable. At the same time, the anti-slip texture 19 inside the base block 15 and the slider 18 contacts the surface of the cable, increasing the friction between them. Finally, the cable is fastened between the slider 18 and the base block 15, thereby achieving the effect of quickly fixing the cable and preventing the cable from loosening and sagging.

[0038] Working Principle: When using this power distribution network planning device, the operator first adjusts the position of the bracket 4 according to the actual operation requirements. When installing the bracket 4, first align the hole on the connecting plate 5 on one side of the bracket 4 with the mounting hole 6 on the support column 1. Then, the operator inserts the outer column 7 into the hole. When the bottom of the outer column 7 is fully inserted into the mounting hole 6, the operator presses down on the linkage column 12, causing the limiting block 13 on its outer wall to pass through the limiting plate 9 and compressing the return spring 14. At the same time, the inner column 10 and the limiting groove 11 are displaced downwards. The displacement of the limiting groove 11 causes the ball bearing 8 inside to roll into the groove inside the mounting hole 6. Then, the linkage column 12 is rotated, causing the limiting block 13 to rotate. Then, the linkage column 12 is released, and under the counter-pushing force of the restoring spring 14, the limiting block 13 is released. Block 13 is stuck below the limiting plate 9 and cannot be reset, thus limiting the current position of the inner column 10, so that the ball 8 is stably stuck inside the mounting hole 6, thereby achieving the effect of quickly fixing the bracket 4. After fixing the position of the bracket 4, the construction personnel pass the cable through the gap between the base block 15 and the fixing block 16 in sequence. Then the construction personnel turn the handle 21. The rotation of the handle 21 drives the threaded rod 20 to rotate synchronously. Under the interaction of the thread on the outer wall of the threaded rod 20 and the thread on the inner wall of the fixing block 16, the rotation of the threaded rod 20 is converted into downward displacement, which causes the slider 18 to slide downward under the guidance of the connecting rod 17, so that its bottom gradually approaches the cable, and finally secures the cable between it and the base block 15, thereby achieving the effect of quickly fixing the cable and preventing the cable from loosening and sagging.
