Examples

As shown in fig. 1-3, the utility model provides a wind-resistant power transmission tower, the structure of which includes a fixing base 1, a tower pole 2, a wiring board 3, a lamp 4 and a wind-resistant block 5, wherein the fixing base 1 is fixedly connected with the tower pole 2, the wiring board 3 is connected with the tower pole 2 by bolts, the lamp 4 is fixedly embedded on the tower pole 2, and the wind-resistant block 5 is installed on the tower pole 2; the wind-resistant block 5 comprises a protective shell A, a limiting groove B, a ball C, a connecting shaft D, a ball sleeve E, a gravity ball F, a connecting block G, a bearing H, a damper I and a rolling connecting plate J, wherein the limiting groove B and the protective shell A are integrally formed, the ball C is installed in the limiting groove B, the connecting shaft D is welded with the ball C, the ball sleeve E is movably clamped with the connecting shaft D, the gravity ball F is installed in the ball sleeve E, the connecting block G is fixedly connected with the protective shell B, the damper I is movably clamped with the connecting block G through the bearing H, the damper I is in surface contact with the gravity ball F through the rolling connecting plate J, the number of the dampers I and the rolling connecting plate J is four, the dampers I are in surface contact with the gravity ball F through the rolling connecting plate J, the gravity ball F is of a solid structure, the limiting groove B is of an incomplete circular groove structure, the connecting surface of the rolling connecting plate J is provided with a plurality of pressed ball structures, the mass of the gravity ball F is 1% of the weight of the whole power transmission tower, and the opening angle of the limiting groove B is 60 degrees.

The working principle of the present invention is explained as follows: when strong wind blows, the strong wind applies wind force on the tower pole 2, the fixed seat 1 at the bottom of the tower pole 2 is fixed on the ground, the tower pole 2 has certain elasticity, is bent and vibrates repeatedly back and forth, the wind-proof block 5 arranged on the tower pole 3 starts to operate at the moment, when the bending vibration of the tower pole 2 starts, the protective shell A is driven to deflect simultaneously, the limiting groove B moves at the moment, but the ball C does not move, the connecting shaft D and the ball sleeve E which are connected with the ball C and the gravity ball F arranged on the ball sleeve E cannot move immediately due to inertia effect, so that the gravity ball F and the tower pole 2 generate a movement time difference, when the tower pole 2 drives the protective shell A to move, the gravity ball F does not move, and the damper I is connected with the gravity ball F, therefore, if the tower pole 2 inclines towards the left side, the damper I on the left side is compressed, the damper I on the right side is stretched, and a force opposite to the wind force direction is generated, the action of most of wind force is counteracted, when the tower pole 2 rebounds, the gravity ball F moves in the opposite direction due to the time difference, a force opposite to the rebounding direction of the tower pole 2 is generated, the elastic force generated by the bending of the tower pole 2 is counteracted, and therefore the tower pole 2 can be quickly restored to be calm.
