[0031] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0032] The following describes a tower foot reinforcement device for a power transmission angle steel tower according to an embodiment of the present invention with reference to the accompanying drawings.

[0033] like Figures 1 to 8 As shown, an embodiment of the present invention provides a tower foot reinforcement device for a power transmission angle steel tower, comprising: a support reinforcement assembly 1, comprising a support frame 2, an extension rod 4, an L-shaped limit plate 5, a limit block 7 and a sliding block 9, the extension rod 4 is arranged inside the support frame 2, the sliding block 9 is arranged on the outside of the extension rod 4, the L-shaped limit plate 5 is arranged at the top of the sliding block 9, the limit block 7 is arranged on the top surface of the support frame 2, and a fixing groove 6 is opened on the top surface of the L-shaped limit plate 5, and the size of the fixing groove 6 is adapted to the limit block 7; sliding grooves 3 are opened on both sides of the support frame 2, and a circular baffle 8 is provided on one side of the sliding block 9, and the circular baffle 8 is arranged on the outside of the sliding groove 3; one end of the extension rod 4 is provided with a rotating shaft 10, and a support rod 11 is provided on the outside of the rotating shaft 10, and one end of the support rod 11 is provided with a gripping plate 12, and the bottom surface of the gripping plate 12 is provided with anti-slip grooves.

[0034] In specific applications of the embodiments of the present invention, according to the working environment and usage site of the transmission angle steel tower, the user stretches or shortens the spacing of the extension rod 4 inside the support frame 2 (stretching the extension rod 4 increases the overall load-bearing capacity of the device, and shortening the extension rod 4 facilitates maintenance of the device as a whole), and stretches the extension rod 4 outward through the sliding block 9. When it is extended to a certain length, the extension rod 4 is locked inside the support frame 2 through the cooperation of the L-shaped limit plate 5 and the limit block 7, thereby fixing the extension rod 4. The rotating shaft 10 on one side of the extension rod 4 has a self-locking function. According to the required tilt angle, the support rod 11 is rotated a certain angle through the rotating shaft 10 to facilitate improving the overall stability of the device.

[0035] When the first electric telescopic device 15 works, it drives the connecting block 29 to move downward, so that the support reinforcement component 1 will be buried deep in the soil, providing greater friction between the support reinforcement component and the soil, thereby more effectively resisting wind and water.

[0036] The first electric telescoping device 15 works, driving the connecting block 29 to move upward, and retracting the extension rod 4 inward through the sliding block 9. When it is retracted to a certain length, the extension rod 4 is locked inside the support frame 2 through the cooperation of the L-shaped limit plate 5 and the limit block 7, thereby fixing the extension rod 4. After that, the support rod 11 is rotated a certain angle through the rotating shaft 10, and the support rod 11 and the gripping plate 12 can be stored at the bottom of the device, which is convenient for disassembly and maintenance of the entire device.

[0037] In a possible embodiment, the transmission angle steel tower foot reinforcement device also includes: a fixing frame 13; a limiting groove 14 is respectively provided on both sides of the fixing frame 13, and a first electric retractor 15 is provided inside the limiting groove 14. The working end of the first electric retractor 15 is provided with a connecting block 29, and the support reinforcement component 1 is provided on one side of the connecting block 29.

[0038] In a specific application of the embodiment of the present invention, the fixing frame 13 is placed on the ground, and the tower foot 28 is placed inside the fixing frame 13. When the first electric telescopic device 15 works, it will drive the connecting block 29 at its working end to move up and down (moving downward will bury the support reinforcement assembly 1 deep in the soil, further reinforcing the tower foot 28; moving upward will facilitate the subsequent maintenance of the device).

[0039] In a possible embodiment, the tower foot reinforcement device of the power transmission angle steel tower also includes: a tower foot 28; a groove 16 is opened inside the fixing frame 13, a circular bearing plate 19 is provided inside the groove 16, and the bottom end of the tower foot 28 is provided on the top surface of the circular bearing plate 19; a damping rod 30 is provided on the bottom surface of the circular bearing plate 19, and a buffer spring 31 is wound around the outer wall of the damping rod 30.

[0040] In a specific application of an embodiment of the present invention, the tower foot 28 is placed in the groove 16 inside the fixing frame 13. As the tower foot 28 enters the depth of the groove 16, the force will gradually be transmitted to the circular supporting plate 19. The circular supporting plate 19 will descend inside the groove 16, and the damping rod 30 and buffer spring 31 at its bottom will relieve the generated force, thereby protecting the tower foot 28.

[0041] In a possible embodiment, a mounting groove 17 is further provided inside the fixing frame 13, and connecting rods 20 are respectively provided on both sides of the circular supporting plate 19. One end of the connecting rod 20 is provided inside the mounting groove 17, and a first magnetic block 21 is provided on the inner wall of the mounting groove 17, and a corresponding second magnetic block 22 is provided on the top surface of the connecting rod 20.

[0042] In a specific application of the embodiment of the present invention, in the initial state, the first magnetic block 21 and the second magnetic block 22 attract each other to fix the connecting rod 20. When the circular supporting plate 19 descends inside the groove 16, it will drive the connecting rods 20 at both ends thereof to move downward inside the mounting groove 17 until the force applied to the circular supporting plate 19 is greater than the magnetic attraction between the first magnetic block 21 and the second magnetic block 22, and the first magnetic block 21 and the second magnetic block 22 are separated. After that, the connecting rod 20 will contact the first electric retractor control module 23 and the second electric retractor control module 24 at the bottom of the inner wall of the mounting groove 17, so that the first electric retractor 15 and the second electric retractor 25 start to work autonomously.

[0043] In one possible embodiment, a through groove 18 is provided on the top surface of the fixing frame 13, and a second electric telescopic device 25 is provided inside the through groove 18. A telescopic connecting rod 26 is provided at the working end of the second electric telescopic device 25, and a fixed ring plate 27 is provided at the other end of the telescopic connecting rod 26. The fixed ring plate 27 is provided on the outer wall of the tower foot 28.

[0044] In specific applications of the embodiment of the present invention, the second electric telescopic device 25 drives the telescopic connecting rod 26 at one end thereof to approach the tower foot 28, and the two sets of fixed ring plates 27 clamp and fix the two sides of the tower foot 28 to prevent the tower foot 28 from being unevenly stressed and shifted. At the same time, the fixed ring plates 27 are selected according to the size of the tower foot 28, thereby effectively adapting to the use of different tower feet 28.

[0045] In a possible embodiment, a first electric retractor control module 23 and a second electric retractor control module 24 are respectively provided on the inner sides of the two groups of mounting grooves 17. The first electric retractor control module 23 is electrically connected to the first electric retractor 15 through a conductive line, and the second electric retractor control module 24 is electrically connected to the second electric retractor 25 through a conductive line.

[0046] In specific applications of the embodiments of the present invention, the first electric telescopic device 15 and the second electric telescopic device 25 used in the device are both mature existing technologies, and the working principles of the first electric telescopic device 15 and the second electric telescopic device 25 are also well known to people in this technical field and will not be described in detail here.

[0047] When the present invention is used, the fixing frame 13 is placed on the ground, and the tower foot 28 is placed in the groove 16 inside the fixing frame 13. As the tower foot 28 enters the depth of the groove 16, the force will gradually be transmitted to the circular supporting plate 19, and the circular supporting plate 19 will descend inside the groove 16.

[0048] Specifically, when the circular supporting plate 19 descends inside the groove 16, it will drive the connecting rods 20 at both ends of it to move downward inside the mounting groove 17 until the force applied to the circular supporting plate 19 is greater than the attraction between the first magnetic block 21 and the second magnetic block 22, and the first magnetic block 21 and the second magnetic block 22 are separated. Then, the connecting rod 20 will contact the first electric telescopic device control module 23 and the second electric telescopic device control module 24 at the bottom of the inner wall of the mounting groove 17, so that the first electric telescopic device 15 and the second electric telescopic device 25 start to work autonomously.

[0049] Specifically, the user stretches the extension rod 4 outward through the sliding block 9. When it is extended to a certain length, the extension rod 4 is locked inside the support frame 2 through the cooperation of the L-shaped limit plate 5 and the limit block 7, thereby fixing the extension rod 4. The rotating shaft 10 on one side of the extension rod 4 has a self-locking function. According to the required tilt angle, the support rod 11 is rotated to a certain angle through the rotating shaft 10.

[0050] When the first electric telescopic device 15 works, it drives the connecting block 29 to move downward, so that the support reinforcement assembly 1 will be buried deep in the soil, providing greater friction between the support reinforcement assembly and the soil, and further reinforcing the tower foot 28.

[0051] Specifically, the second electric telescopic device 25 drives the telescopic connecting rod 26 at one end thereof to approach the tower foot 28. The two sets of fixed ring plates 27 will clamp and fix the two sides of the tower foot 28 to prevent the tower foot 28 from being unevenly stressed and shifted. At the same time, the fixed ring plates 27 will be selected according to the size of the tower foot 28, thereby effectively adapting to the use of different tower feet 28.

[0052] Specifically, the first electric telescoping device 15 works, driving the connecting block 29 to move upward, and retracting the extension rod 4 inward through the sliding block 9. When it is retracted to a certain length, the extension rod 4 is locked inside the support frame 2 through the cooperation of the L-shaped limit plate 5 and the limit block 7, thereby fixing the extension rod 4. After that, the support rod 11 is rotated a certain angle through the rotating shaft 10, and the support rod 11 and the gripping plate 12 can be stored at the bottom of the device.
