[0039] In order to solve the above problems, the utility model provides a weather station support, Figures 1 to 2 The specific embodiments of the weather station support provided by the utility model.

[0040] Please refer to Figures 1 to 2The weather station support 100 comprises a fixed rod 1, a rotating rod 2, a mounting frame 3 and a limiting assembly 4; the middle part of the rotating rod 2 is rotationally connected with the axis extending in the horizontal direction of the upper end of the fixed rod 1, and the rotating rod 2 has a limiting end 21 and a mounting end 22; the mounting frame 3 is connected to the mounting end 22 of the rotating rod 2 and is used for mounting weather equipment; and the limiting assembly 4 comprises a flexible traction part 41 and a limiting part 42, and the flexible traction part 41 is connected with the limiting end 21 of the rotating rod 2; wherein the flexible traction part 41 is in a relaxed state, the rotating rod 2 is rotated, so that the mounting end 22 of the rotating rod 2 is tilted downward and is in a replacement position to replace the weather equipment; the flexible traction part 41 is in a tensioned state to tractionally rotate the rotating rod 2 until the limiting end 21 is limitedly matched with the limiting part 42, so that the mounting end 22 of the rotating rod 2 is upright and is in a working position.

[0041] In the technical scheme, the fixed rod 1 is arranged in the up-down direction, the upper end of the fixed rod 1 is rotationally connected with the middle part of the rotating rod 2, the lower end of the fixed rod 1 is used for fixedly connecting with a wind power fan, the middle part of the rotating rod 2 rotates around the rotation shaft, the mounting end 22 of the rotating rod 2 is provided with the mounting frame 3, the mounting frame 3 is provided with weather equipment, the weather equipment can make a circular motion around the rotation shaft, at this time, the mounting frame 3 has an activity stroke from the position above the fixed rod 1 to the lower end of the fixed rod 1, and there is one or more suitable positions suitable for the operator to operate in the rotating stroke, the limiting assembly 4 is mounted on the wind power fan and is fixedly connected with the limiting end 21 of the rotating rod 2, can limit the rotation of the rotating rod 2, and makes the rotating rod 2 keep still at a certain position or multiple positions in the rotating stroke, thereby facilitating the operator to replace and maintain the weather station components.

[0042] Specifically, please refer to Figure 2, the limiting assembly 4 comprises a mounting seat 421, a winding part 422 and a flexible traction rope 411, the mounting seat 421 is fixedly installed on the wind turbine, the winding part 422 is rotatably installed on the mounting seat 421, one end of the flexible traction rope 411 is wound on the winding part 422, and the other end is connected to the limiting end 21 of the rotating rod 2; the winding part 422 is rotated to make the flexible traction rope 411 more wound on the winding part 422, at this time, the flexible traction rope 411 is in a tension state, and in this process, the mounting end 22 is rotated towards the working position; the winding part 422 is rotated to make the flexible traction rope 411 more wound out of the winding part 422, at this time, the flexible traction rope 411 is in a relaxed state, and under the action of gravity of the mounting bracket 3, the mounting end 22 is rotated towards a direction away from the working position, i.e. towards the replacement position. In the prior art, after the rotating rod 2 is rotated to the replacement position and the operator completes the operation, the rotating rod 2 cannot be rotated back to the working position, so that the mounting bracket 3 is rotated to the upper end of the fixed rod 1, and the operator still needs to climb out of the nacelle cover to adjust and manually fix the rotating rod 2 at the mounting position, so that the operation still has safety risks. Therefore, the winding part 422 is arranged to be rotatable, a handle is arranged on the winding part 422, at this time, the operator shakes the handle to rotate the winding part 422, the free length of the flexible traction rope 411 is retracted, the flexible traction rope 411 is wound on the winding part 422, as the free length of the flexible traction rope 411 gradually shortens, the rotating rod 2 is gradually rotated back to the working position, since the winding part 422 is installed on the mounting seat 421, and the mounting seat 421 is installed on the wind turbine, the mounting seat 421 can be installed near the nacelle cover opening, so that the operator can complete the operation without completely climbing out of the nacelle cover opening, thereby reducing the safety risks of the operator. Moreover, the extension speed of the free length of the flexible traction rope 411 can control the rotation speed of the rotating rod 2, the winding part 422 can be slowly rotated, the free length of the flexible traction rope 411 changes slowly, so that the mounting bracket 3 is slowly lowered from the high position to the low position, and the rotating rod 2 is prevented from rotating too fast to impact the limiting part or other parts, so that the meteorological equipment of the mounting bracket 3 is affected.

[0043] Under the action of gravity of the mounting bracket 3, the mounting end 22 is rotated towards a direction away from the working position, for different operators, a suitable operation position can be different, in order to fix near any position in the rotation process of the mounting end 22, please refer to Figure 2The limiting part 42 further comprises a limiting pin 423, the winding part 422 is provided with a plurality of limiting holes 4221 in the circumferential direction, the mounting seat 421 is provided with a positioning hole 4211, the positioning hole 4211 and the limiting hole 4221 are correspondingly arranged, the limiting pin 423 is arranged through the positioning hole 4211 and one of the limiting holes 4221, the rotation of the winding part 422 controls the extension of the free length of the flexible traction rope 411 to control the rotation of the rotating rod 2, after the mounting rack 3 is rotated to the appropriate position, the positioning hole 4211 and one of the limiting holes 4221 are rotated to the corresponding position, and then the limiting pin 423 is arranged through the positioning hole 4211 and the limiting hole 4221, at this time, the mounting rack 3 can be rotated to the high position, but under the influence of gravity, the mounting rack 3 can only be rotated to the low position, but due to the limiting effect of the limiting pin 423 on the winding part 422, the free length of the flexible traction rope 411 cannot be increased, so the mounting rack 3 cannot be rotated to the low position, and the mounting rack 3 remains stationary at this position.

[0044] When the mounting rack 3 is located at the highest position on the rotating stroke (i.e. the working position), the rotating rod 2 can have two rotating directions, in order to rotate the mounting rack 3 to the side close to the operator and on the rotating stroke of the limiting end 21 of the rotating rod 2, so as to abut against the limiting end 21 and facilitate the work of the operator, please refer to Figure 2 Therefore, the weather station support 100 further comprises a stop block 5, the stop block 5 is fixedly arranged on the fixed rod 1 and located on the same side of the mounting seat 421 of the fixed rod 1, the rotating direction of the rotating rod 2 can only be that the mounting rack 3 inclines to the side of the mounting seat 421, that is, the limiting end 21 of the rotating rod 2 rotates away from the mounting seat 421. In this way, the operator can operate the winding part 422 on the side of the fixed rod 1 located on the mounting seat 421, so that the mounting rack 3 can be rotated to the appropriate replacement position on the side of the fixed rod 1 located on the mounting seat 421, and the operator does not need to move on both sides of the fixed rod 1 to operate, which facilitates the operation of the operator and improves the practicability.

[0045] In order to prevent the rotating rod 2 from rotating too fast and colliding with the limiting part or other parts, thereby affecting the weather equipment of the mounting rack 3, a damping hinge 6 can be further arranged at the rotating shaft. Please refer to Figure 1 The damping hinge 6 has two connecting ends relatively rotating, and the two connecting ends are fixedly connected with the upper end of the fixed rod 1 and the middle part of the rotating rod 2 respectively. Because the damping hinge 6 can hinder the relative movement between the movable parts, the rotating speed of the rotating rod 2 is reduced, the rotation is more stable, and the rod is prevented from being impacted too much, thereby affecting the weather equipment.

[0046] After the operator operation is completed, the rotating rod 2 is rotated back to the working position and fixed, at this time, only the flexible traction rope 411 is unreliable for limiting the rotating rod 2, in order to firmly fix the rotating rod 2 in the working position, please refer to Figure 1 The weather station support 100 further comprises a fixing pin 7, the lower end of the fixed rod 1 and the limiting end 21 of the rotating rod 2 are respectively provided with through holes 11, the two through holes 11 are correspondingly arranged, the fixing pin 7 is arranged through the two through holes 11, and the rotation of the rotating rod 2 is limited. When rotation is needed, the fixing pin 7 is pulled out.
