[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 7 As shown, in an embodiment of the present invention, an adjustable transmission tower foundation reinforcement base includes a base 1, a plug rod 2 is fixedly installed at the bottom end of the base 1, and the plug rod 2 is arranged at the four corners of the bottom of the base 1. A slider 3 is arranged inside the base 1, and two sliders 3 are arranged. The tops of the two sliders 3 are both installed with a support assembly, and the two sliders 3 are both installed inside the base 1 through an adjustment assembly; The support assembly includes a first connector 4 installed at the top of the slider 3, the slider 3 and the first connector 4 are rotatably connected through a rotating assembly, the top of the first connector 4 is fixedly connected to a support rod 5, the top of the support rod 5 is provided with a rotating block 7, the top of the rotating block 7 is installed with a second connector 8, the top of the second connector 8 is hinged with a connecting seat 9, and the top of the connecting seat 9 is fixedly installed with an ear plate 10; The adjustment assembly includes a threaded rod 11 installed inside the base 1. The threaded rod 11 is rotatably installed inside the base 1 through a power assembly. Both ends of the threaded rod 11 are respectively embedded in the two sliders 3. The threaded rod 11 and the sliders 3 are threadedly connected.

[0021] When installing the transmission tower, the threaded rod 11 can be driven to rotate by the power component, and the rotation of the threaded rod 11 drives the slider 3 to move, and the movement of the slider 3 drives the first connector 4 and the support rod 5 to move, so that the second connector 8, the connecting seat 9 and the ear plate 10 move synchronously, and the distance between the two groups of support components is adjusted to adapt to the installation of the transmission tower in various terrains, so as to maintain the stability and safety of the tower, extend the service life of the tower, and reduce the economic losses caused by damage or collapse of the tower.

[0022] like Figure 3 and Figure 4 As shown, the power assembly includes a worm wheel 12 fixedly mounted on the outer wall of the threaded rod 11 , one side of the worm wheel 12 is meshingly connected with a worm 13 , and a motor 14 is mounted at the bottom end of the worm 13 .

[0023] When adjusting the distance between the two groups of support components, the motor 14 is started. The starting of the motor 14 drives the rotation of the worm 13. The rotation of the worm 13 drives the rotation of the worm wheel 12, thereby driving the threaded rod 11 to rotate. The transmission is through the worm 13 and the worm wheel 12. It not only has a smooth transmission characteristic but also has a self-locking performance, thereby improving the stability and reliability of the device.

[0024] like Figure 3 As shown, two threads are arranged on the outer wall of the threaded rod 11, and the directions of the two threads are opposite.

[0025] When the threaded rod 11 is rotated, the two slide blocks 3 are moved relative to each other at the same time, thereby improving the adjustment efficiency.

[0026] like Figure 6 and Figure 7 As shown, the rotating assembly includes a first rotating shaft 18 embedded in the slider 3, both ends of the first rotating shaft 18 are fixedly mounted on the inner wall of the first connecting head 4, a pulley group 19 is installed on the outer wall of the first rotating shaft 18, and a second rotating shaft 20 is installed inside the bottom end of the pulley group 19. The second rotating shaft 20 is rotatably mounted inside the slider 3 through a transmission assembly.

[0027] When the slider 3 moves inside the base 1, the second rotating shaft 20 is driven to rotate through the transmission assembly. When the second rotating shaft 20 rotates, the first rotating shaft 18 is driven to rotate through the pulley group 19. The rotation of the first rotating shaft 18 drives the first connecting head 4 to rotate, so that the angle of the first connecting head 4 can be adjusted during the movement and adjustment of the slider 3, thereby optimizing the overall structure of the tower and making it more resistant to the influence of natural forces such as strong winds.

[0028] like Figure 7 As shown, the transmission assembly includes a first gear 21 fixedly mounted on the outer wall of the second rotating shaft 20, the bottom end of the first gear 21 is meshedly connected with the second gear 22, the interior of the second gear 22 is fixedly mounted with a third rotating shaft 23, the bottom end of the second gear 22 is meshedly connected with the third gear 24, the interior of the third gear 24 is fixedly mounted with a fourth rotating shaft 25, the bottom end of the third gear 24 is meshedly connected with a rack plate 26, and the rack plate 26 is fixedly mounted inside the base 1.

[0029] The inner wall diameters between the first gear 21, the second gear 22 and the third gear 24 increase gradually; When the slider 3 moves, it drives the third gear 24 to move on the top of the rack plate 26, and the third gear 24 meshes with the rack plate 26 to rotate. The rotation of the third gear 24 drives the rotation of the second gear 22, and the rotation of the second gear 22 drives the rotation of the first gear 21, thereby driving the second rotating shaft 20 to rotate. The rotation angle of the first connecting head 4 is controlled by the first gear 21, the second gear 22 and the third gear 24, so that the inclination angle of the first connecting head 4 is slowly adjusted, which helps the tower structure to gradually adapt to the new stress state and reduce the structural damage caused by stress mutation.

[0030] like Figure 6 As shown, an adjusting rod 6 is fixedly mounted on the bottom end of the rotating block 7, and the adjusting rod 6 is embedded in the supporting rod 5 and is threadedly connected.

[0031] When it is necessary to adjust the length of the support assembly, rotate the rotating block 7 to drive the adjusting rod 6 to slide out of the support rod 5 to adjust the length of the entire support assembly. This prevents the ground from being uneven or sinking because the transmission tower is often built in a complex terrain environment. By adjusting the length of the support rod 5, it can be ensured that the bottom of the tower maintains stable contact with the ground, thereby reducing the tilt or shaking of the tower caused by terrain changes.

[0032] like Figure 6 As shown, the rotating block 7 and the second connecting head 8 are rotationally connected.

[0033] When adjusting the distance between the first connector 4 and the second connector 8, the second connector 8 does not rotate when the rotating block 7 is rotated for adjustment, so that the ear plate 10 is connected toward one side of the transmission tower.

[0034] like Figures 1 to 7 As shown, both sides of the slider 3 are fixedly connected with protection belts 15 , and the ends of the two protection belts 15 away from the slider 3 are both installed with the outer wall of the winding roller 16 .

[0035] A slide groove for the slider 3 to slide is provided inside the base 1, and the slide groove between the slider 3 and the base 1 is protected by a protective belt 15 to prevent the slide groove from being eroded and damaged by the external environment, thereby maintaining the integrity and stability of its structure.

[0036] like Figure 5 As shown, the winding roller 16 is rotatably installed inside the base 1 , and a coil spring 17 is installed on the outer wall of the winding roller 16 .

[0037] The reel 16 is constantly reeling the protective belt 15 by the elastic potential energy of the coil spring 17 . When the slider 3 moves, the protective belt 15 is always at a certain tension and is located at the slide groove.

[0038] A method for reinforcing an adjustable transmission tower foundation reinforcement base comprises the following steps: S201. When installing a transmission tower, start the motor to drive the worm, worm wheel and threaded rod to rotate in sequence.

[0039] When installing the transmission tower, the motor 14 is started, and the starting of the motor 14 drives the rotation of the worm 13 , and the rotation of the worm 13 drives the rotation of the worm wheel 12 , thereby driving the threaded rod 11 to rotate.

[0040] S202, the rotation of the threaded rod drives the slider, the first connector and the support rod to move, so that the second connector, the connecting seat and the ear plate move synchronously, and the distance between the two groups of support components is adjusted.

[0041] The rotation of the threaded rod 11 drives the slider 3 to move, and the movement of the slider 3 drives the first connector 4 and the support rod 5 to move, so that the second connector 8, the connecting seat 9 and the ear plate 10 move synchronously to adjust the distance between the two groups of support components.

[0042] S203, when the slider moves, it drives the third gear to move on the top of the rack plate, and the rotation of the third gear is transmitted to the second gear and the first gear in sequence, driving the second rotating shaft to rotate.

[0043] When the slider 3 moves, it drives the third gear 24 to move on the top of the rack plate 26. The third gear 24 meshes with the rack plate 26 and rotates. The rotation of the third gear 24 drives the rotation of the second gear 22. The rotation of the second gear 22 drives the rotation of the first gear 21, thereby driving the second rotating shaft 20 to rotate.

[0044] S204: When the second rotating shaft rotates, the first rotating shaft and the first connecting head are driven to rotate in sequence through the pulley set, so that the angle of the first connecting head is adjusted during the movement and adjustment of the slider.

[0045] When the second rotating shaft 20 rotates, the first rotating shaft 18 is driven to rotate through the pulley set 19 . The rotation of the first rotating shaft 18 drives the first connecting head 4 to rotate, so that the angle of the first connecting head 4 is adjusted during the movement and adjustment of the slider 3 .

[0046] S205. At the same time, the rotating block drives the adjusting rod to slide out from the supporting rod to adjust the length of the overall supporting assembly.

[0047] By rotating the rotating block 7, the adjusting rod 6 is driven to slide out from the supporting rod 5 to adjust the length of the entire supporting assembly.

[0048] S206, rotating the connecting seat to make the ear plate fit and connect with the outer wall of the iron tower.

[0049] Finally, the connecting seat 9 is rotated to make the ear plate 10 fit with the outer wall of the iron tower and connect them.
