[0002] Transmission towers are important supporting components for laying high-altitude electric wires, and are also one of the commonly used supporting and fixing methods in current power transmission projects. The stability of the base of the transmission tower is ensured by placing the four corners of the bottom end of the transmission tower on a reinforced concrete foundation, and then using screws and nuts to connect and fix them.

[0003] The base of current transmission towers is mainly fixed by screws and nuts. However, the screws and nuts are exposed to wind and rain for a long time, and will inevitably rust or become loose due to external influences. Once loose, it will directly affect the stability of the transmission tower. Therefore, a UHV transmission tower base reinforcement structure is proposed. Utility Model Content

DETAILED DESCRIPTION

[0015] The utility model will be further described below in conjunction with the accompanying drawings.

[0016] Please refer to Figure 1-4 The utility model discloses a reinforcement structure for the base of an ultra-high voltage transmission tower, comprising a tower body 1, wherein the bottom end of the tower body 1 is fixedly connected to a base 2, and screw rods 3 are inserted and connected to the four corners of the base 2, and one end of the screw rod 3 located below the base 2 is pre-buried in a cement foundation, and one end of the screw rod 3 located above the base 2 is threadedly connected to a nut 4, and a cap 5 is sleeved on the nut 4, and plug rods 6 are inserted and connected to the cap 5 near both side edges, a slot 7 is provided at a position opposite to the plug rod 6, and a through slot is provided at a position opposite to the slot 7, and side grooves 13 are provided at both side edges of the top of the cap 5, and a bottom follower rod 8 is detachably and rotatably connected in one of the side grooves 13;

[0017] A sleeve hole is provided through the middle of the top side wall of the cap 5, and a bottom column 14 is provided at the bottom end of the insertion rod 6 passing through the cap 5. The insertion rod 6 and the bottom column 14 pass through the through groove on the nut 4 and are inserted into the slot 7. A buckle 15 is fixedly connected in the middle of the side wall opposite to the bottom column 14 and the insertion rod 6. A slot 17 is provided on the side wall opposite to the insertion rod 6 and the buckle 15, and the buckle 15 is inserted into the slot 17. Both side edges of the bottom column 14 and the buckle 15 are rotatably connected with a linkage plate 16, and the two linkage plates 16 are rotatably connected at one end away from the bottom column 14. Side grooves 18 are provided on both side walls of the slot 7, and the linkage plates 16 are inserted into the side grooves 18.

[0018] The technical effect of this scheme is as follows: the screw rod 3 is pre-buried in the cement foundation, and then the screw rod 3 is sleeved on the screw rod 3 through the holes at the four corners, and then the nut 4 is threadedly connected to the screw rod 3, the cap 5 is sleeved on the screw 3 and finally on the nut 4, and then the insertion rod 6 is pressed and inserted into the slot 7. As the insertion rod 6 is pressed, the linkage plate 16 will be pressed, and the linkage plate 16 will expand outward under pressure until it becomes horizontal. At the same time, the linkage plate 16 will also be inserted into the corresponding side groove 18, and the buckle 15 will also be snapped in the insertion rod 6, so as to limit the cap 5. The covering of the cap 5 can protect and suppress the nut 4 and the screw rod 3 to avoid the problem of rust caused by external factors on the nut 4 and the screw 3. At the same time, the nut 4 is pressed and limited to avoid the problem of loosening of the nut 4 and causing instability of the tower body 1.

[0019] A bottom telescopic screw 9 is fixedly connected to the middle of the side wall of the end of the bottom follower rod 8 away from the cap 5, an adjusting column 10 is set up at the end of the bottom telescopic screw 9 away from the bottom follower rod 8, a top telescopic screw 11 is set up on the side of the adjusting column 10 away from the bottom telescopic screw 9, and a top follower rod 12 is fixedly connected to the end of the top telescopic screw 11 away from the adjusting column 10. The top follower rod 12 is detachably connected to the side wall of the tower body 1 through the end away from the top telescopic screw 11, and screw sleeves 19 are fixedly connected in the middle of the side walls of the adjusting column 10 on both sides opposite to the top telescopic screw 11 and the bottom telescopic screw 9. The adjusting column 10 is a hollow structure and is communicated with the middle of the screw sleeve 19. One end of the top telescopic screw 11 and the bottom telescopic screw 9 are threadedly inserted and connected to the screw sleeve 19 and extend into the adjusting column 10. A driving hole 20 is opened on one side wall of the adjusting column 10, and a wrench column 21 is inserted in the driving hole 20.

[0020] The technical effect of this scheme is as follows: after the cap 5 is stably covered on the nut 4, the top follower rod 12 is connected to the tower body 1, and the bottom follower rod 8 is connected to the corresponding side groove 13, and then the adjusting column 10 is rotated as needed. As the adjusting column 10 rotates, the threaded connection relationship between the top telescopic screw 11 and the bottom telescopic screw 9 and the screw sleeve 19 will drive them to contract or expand, thereby providing support or stretching force for the bottom end of the tower body 1, increasing the stability of the connection with the base 2, and at the same time, the cap 5 itself can be limited by the above method, thereby improving the stability of the cap 5 and enabling it to better protect the nut 4.

[0021] When the bolt 14 is in the state of being loosened, the bolt 14 is in the state of being pressed down, and the bolt 14 is pressed down, so that the bolt 14 can be put on the screw rod 3 and the screw rod 3 is loosened.
