[0002] In the field of high-voltage power transmission, 500KV double-circuit compact tension towers have become a key infrastructure of power transmission networks due to their advantages such as large transmission capacity and narrow corridor width. As power grid construction extends to areas with complex terrain and harsh environments, the stability and reliability of the tower leg structure, as the core component connecting the tension tower to the ground, are directly related to the safe operation of transmission lines.

[0003] During the installation of the tower legs, the workers first need to lay out the positioning on the foundation according to the drawings. Then, they use lifting equipment to hoist the tower legs to the foundation in sections. After initial fixing with bolts and shims, they use instruments to calibrate the verticality and horizontality. Next, they complete the connection and tightening of each section of the tower body. Finally, they conduct a comprehensive inspection and adjustment to ensure that the installation is firm and stable.

[0004] The existing technology has the following drawbacks: on the one hand, the conventional connection method between the tower legs and the ground is difficult to effectively cope with the impact of external forces such as strong winds and earthquakes, as well as ground subsidence, resulting in insufficient tower stability and increasing the risk of transmission line failure. On the other hand, the reinforcement and storage design of the tower leg structure is not reasonable enough, the reinforcement operation is cumbersome and occupies a lot of space, which brings inconvenience to transportation and storage. Therefore, a 500KV double-circuit compact tension tower leg structure is proposed to solve the above problems. Utility Model Content

[0007] The movable mechanism includes an inclined block that is rotatably connected to the outer wall of the rotating rod. The inner wall of the inclined block has an inclined groove, and an insert block is slidably connected to the inner wall of the inclined groove.

[0009] The support assembly includes a long rod hinged to the inner wall of the tower leg, a reinforcing plate hinged to the outer wall of the long rod, and bolts threaded to the inner wall of the reinforcing plate.

[0013] The insert is slidably connected to the inner wall of the cylinder.

[0014] As a further description of the above technical solution:

[0019] The front and right sides of the tower legs are respectively provided with rectangular slots.

[0022] This utility model has the following beneficial effects:

[0023] 1.

[0033] 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.

[0034] Reference Figures 1-3This utility model provides an embodiment of a 500kV double-circuit compact tension tower leg structure, including a tower leg 1. The tower leg 1 is a key component at the bottom of the tower structure, used to support and fix the entire structure. Its function is similar to a "leg," bearing the responsibility of transferring the tower load to the foundation. A fixing plate 2 is fixedly connected to the bottom end of the tower leg 1. A cylinder 3 is fixedly connected to the inner wall of the fixing plate 2. A rotating rod 4 is threadedly connected to the inner wall of the cylinder 3. The upper side of the rotating rod 4 is circular, and an arc-shaped notch is provided around the edge of the circle to facilitate construction. The operator rotates the rotating rod 4. A protective ring 5 is fixedly connected to the inner side wall of the rotating rod 4. The protective ring 5 protects the rotating rod 4 from rain and dust, preventing the rotating rod 4 from being affected by rain and dust, thus affecting its use. The outer wall of the rotating rod 4 is provided with a movable mechanism, and the inner wall of the tower leg 1 is provided with a support assembly. The movable mechanism includes an inclined block 6, which is rotatably connected to the outer wall of the rotating rod 4. The inner wall of the inclined block 6 is provided with an inclined groove. When the inclined groove presses the insert 7, it causes the four sets of inserts 7 to move closer together or separate. The insert 7 is slidably connected to the inner wall of the inclined groove.

[0035] Reference Figure 1 , Figure 2 and Figure 6 The support assembly includes a long rod 8, which is hinged to the inner wall of the tower leg 1. A reinforcing plate 9 is hinged to the outer wall of the long rod 8. When the reinforcing plate 9 is in contact with the ground, the reinforcing plate 9, the tower leg 1, and the long rod 8 form a triangular structure, which can increase the stability of the device during use. A bolt 10 is threadedly connected to the inner wall of the reinforcing plate 9. The reinforcing plate 9 has threads that match the bolt 10. The bolt 10 is threadedly connected to the inner wall of the tower leg 1. The reinforcing plate 9 has threads that match the bolt 10.

[0036] Reference Figures 3-5 The protective ring 5 is circular and is slidably connected to the inner wall of the cylinder 3. The cylinder 3 has a slot corresponding to the protective ring 5, allowing the protective ring 5 to move vertically. The insert block 7 is slidably connected to the inner wall of the cylinder 3. The cylinder 3 has a slot corresponding to the insert block 7, allowing the insert block 7 to move horizontally. The inclined block 6 has a circular opening inside. The smooth surface of the lower end of the rotating rod 4 is provided with annular grooves, so that when the rotating rod 4 rotates, the inclined block 6 does not rotate with the rotating rod 4. The inclined block 6 is slidably connected to the inner wall of the cylinder 3. The cylinder 3 has four sets of openings corresponding to the inclined block 6. The front surface and right side of the tower leg 1 are respectively provided with rectangular slots. The outer side of the insert block 7 is triangular.

[0037] Working principle: When tower leg 1 needs to be installed, manually rotate the rotating rod 4 counterclockwise. The rotating rod 4 will move the inclined block 6 downwards. The inclined groove on the inclined block 6 will squeeze the insert block 7, causing the four sets of insert blocks 7 to separate from each other. When the insert block 7 is inserted into the soil, it will increase the friction between the device and the ground, increasing the stability of the device. Then, manually rotate the bolt 10 clockwise. When the bolt 10 separates from the reinforcing plate 9, manually flip the reinforcing plate 9 downwards to make the reinforcing plate 9 fit with the ground. Then, use the bolt 10 to fix the reinforcing plate 9 to the ground. The connection between the reinforcing plate 9, tower leg 1 and long rod 8 forms a triangle, which further improves the stability of tower leg 1.

[0038] When tower leg 1 needs to be retracted, manually rotate the rotating rod 4 clockwise. The rotating rod 4 will move the inclined block 6 upward. The inclined groove on the inclined block 6 will bring the four sets of insert blocks 7 closer together. When the insert blocks 7 enter the cylinder 3, manually release the rotating rod 4. Then manually rotate the bolt 10. When the bolt 10 separates from the reinforcing plate 9, manually flip the reinforcing plate 9 upward. When the reinforcing plate 9 is in contact with tower leg 1, manually insert the bolt 10 into the groove of the reinforcing plate 9 and rotate the bolt 10 to complete the limiting of the reinforcing plate 9.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
