[0002] Transmission towers are important supports for high-voltage power transmission lines, and their stability and safety are directly related to the normal operation of the power grid. However, due to factors such as complex terrain and changeable climatic conditions, towers may encounter challenges such as foundation settlement, wind effects, and earthquake impacts during use.

[0003] For example, a stable support structure for an electric power tower with the publication (announcement) number CN213039005U relates to the technical field of electric power towers. The stable support structure for the electric power tower comprises an iron tower body and a base, wherein a fixed pile is pre-buried at the top of the base, the bottom of the iron tower body is fixedly connected to the top of the fixed pile, the top of the base is fixedly connected to a square cover, the square cover is movably sleeved on the surface of the fixed pile, the side of the square cover is fixedly connected to a cross plate, the upper surface of the cross plate is fixedly connected to a first connecting seat, and the surface of the fixed shaft fixedly connected to the inner wall of the first connecting seat is movably sleeved with a screw. The utility model solves the problem in the prior art that, when the currently common electric power tower is in use, the contact area between the electric power tower and the concrete base is small and the connection method is single, thereby resulting in poor connection firmness between the electric power tower and the concrete base.

[0004] However, based on the working principle proposed in the above patent, the applicant believes that the above device can only reinforce the base of the tower, but cannot support the height of the tower. When the tower is facing strong winds, the connection between the tower modules is prone to stress concentration, which may cause the tower to tilt or even be damaged.

[0005] Therefore, in order to solve the above problems, an adaptive support structure for a transmission tower is proposed. Utility Model Content

[0008] Preferably, a lower circular limiting groove is provided in the middle portion of the top of the base, and a power transmission tower is fixedly mounted on the top of the base.

[0009] Preferably, a connecting plate is fixedly installed at the middle part of the inner side of the transmission tower, and an upper circular limiting groove is provided at the bottom of the connecting plate.

[0010] Preferably, a mounting plate is fixedly mounted on the top of the transmission tower, an extension rod is threadedly connected to the middle portion of the top of the mounting plate, and a wind speed and direction sensor is threadedly connected to the top of the extension rod.

[0011] Preferably, support legs are installed at the four corners of the bottom of the base, and a circular positioning plate is fixedly installed at the bottom of the support legs.

[0012] Preferably, a bidirectional threaded rod is movably installed inside the support rod, an adjustment block is fixedly installed in the middle part of the bidirectional threaded rod, and the threads on the surface of the bidirectional threaded rod are opposite.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model realizes the function of providing additional supporting force for the tower body through the structural design of the base, drive motor, rotating shaft, first eccentric plate, second eccentric plate, support rod and arc-shaped support block, thereby providing support for the tower body in different directions, absorbing and dispersing external forces such as wind loads, reducing the vibration and tilt of the iron tower, avoiding the concentration of force at the connection of the tower body, thereby improving its wind resistance and overall stability, and solving the problem of being unable to support the tower body.

[0023] The following is combined with Figure 1-4 To further explain this application,

[0026] A lower circular limiting groove 3 is formed in the middle part of the top of the base 1, and a power transmission tower frame 4 is fixedly installed on the top of the base 1.

[0027] Referring to Figure 1 , through the structural design of the lower circular limiting groove 3, the function of limiting the lower arc-shaped support block 208 is realized, so that the movement space of the lower arc-shaped support block 208 can be provided and limited, the displacement or instability of the support rod 207 due to external force or other reasons is avoided, and the stable support force provided by the support rod 207 is ensured.

[0028] A connecting plate 5 is fixedly installed in the middle part of the inner side of the power transmission tower frame 4, and an upper circular limiting groove 6 is formed in the bottom of the connecting plate 5.

[0029] Referring to Figure 2 , through the upper circular limiting groove 6, the movement space of the upper arc-shaped support block 208 can be provided and limited, the support rod 207 is ensured to be fixed at a predetermined position and angle after installation, and the stable transmission of the support force to the tower body is ensured, and the vibration and stress of the tower structure caused by the support rod 207 absorbing and transmitting external forces such as wind load are ensured.

[0030] An installation plate 7 is fixedly installed on the top of the power transmission tower frame 4, an extension rod 8 is screw-connected to the middle part of the top of the installation plate 7, and a wind speed and direction sensor 9 is screw-connected to the top of the extension rod 8.

[0031] Reference Figure 1 The extension rod 8 facilitates the carrying of the wind speed and direction sensor 9 and ensures the stability of the wind speed and direction sensor 9. The wind speed and direction sensor 9 realizes the function of real-time detection of wind speed and direction, thereby facilitating the subsequent real-time adjustment of the working state of the support mechanism 2, thereby achieving the purpose of adaptive support.

[0032] Support legs 10 are installed at the four corners of the bottom of the base 1 , and a circular positioning plate 11 is fixedly installed at the bottom of the support legs 10 .

[0033] Reference Figure 1 and Figure 2 The circular positioning plate 11 is used to increase the contact area between the support leg 10 and the installation surface, while reducing the possibility of the base 1 tilting, and also facilitates the quick installation and disassembly of the base 1.

[0034] A bidirectional threaded rod 12 is movably installed inside the support rod 207 , an adjustment block 13 is fixedly installed in the middle of the bidirectional threaded rod 12 , and the threads on the surfaces of the bidirectional threaded rod 12 are opposite.

[0035] Reference Figure 4 The bidirectional threaded rod 12 and the adjusting block 13 are used to adjust the support rod 207 by rotation, and the connection of the support rod 207 is made more convenient and quick.

[0036] Working principle: When using this device, the bidirectional threaded rod 12 is driven to rotate by the adjusting block 13, and the bidirectional threaded rod 12 is used to push the support rod 207 to both sides so that the support rod 207 is adapted to the transmission tower 4. The wind speed and direction sensor 9 is used to detect the wind force in real time, and the detection signal is transmitted to the terminal connected thereto in real time. The terminal issues a command to start the drive motor 201, and the drive motor 201 drives the rotating shaft 202 to rotate, and the rotating shaft 202 drives the first eccentric plate 203 to rotate, and the first eccentric plate 203 drives the connecting rod 204 to drive the second eccentric plate 205 to rotate synchronously, and the inclined hole 206 at the first eccentric plate 203 cooperates with the second eccentric plate 2 The inclined hole 206 at 05 limits the support rod 207 and drives the support rod 207 to rotate. As the support rod 207 rotates, the lower circular limiting groove 3 limits the arc-shaped support block 208 at the bottom. At the same time, the upper circular limiting groove 6 limits the top arc-shaped support block 208. When the top arc-shaped support block 208 is opposite to the wind direction, the drive motor 201 stops working. When strong wind releases the force to the transmission tower 4, the transmission tower 4 transmits it to the top arc-shaped support block 208 through the connecting plate 5. The top arc-shaped support block 208 is transmitted to the bottom arc-shaped support block 208 through the support rod 207, and finally transmitted to the base 1 through the bottom arc-shaped support block 208.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
