Two reversely rotatable support rods are rotatably connected to the back of the pull rod. The two support rods can respectively abut against the two cross rods;

[0009] A large arm structure is arranged on one side of the cross rod for installation and support. The large arm structure includes a cross arm, a connecting seat and a fixing block. The fixing block is fixedly connected to the cross rod. The cross arm is rotatably connected to the fixing block. The connecting seat is fixedly arranged on the top of the cross arm;

[0010] A limiting component is arranged between the cross arm and the fixing block for adjusting and locking the angle of the cross arm.

The limiting shaft is fixedly connected to the cross arm and rotatably connected to the fixing block. The sliding sleeve is slidably connected to the limiting shaft. The nut is threadedly connected to the limiting shaft.

[0012] As a preferred embodiment of the present utility model, a limiting groove is radially formed on the circumferential surface of the limiting shaft. The sliding sleeve is annular, and an integrally formed rib is provided on the inner ring of the sliding sleeve. The rib is slidably connected to the limiting groove.

[0013] As a preferred embodiment of the present utility model, a plurality of thrust grooves are formed on the top of the fixed block. The thrust grooves are rectangular, and the ribs on the wall surface of the sliding sleeve can be inserted into the thrust grooves.

[0014] As a preferred embodiment of the present utility model, a bushing is fixedly installed at the bottom of the fixed block. The limiting shaft is rotatably connected to the bushing. The limiting shaft penetrates through the fixed block, and the lower end surface of the limiting shaft is fixedly connected to the top of the cross arm.

[0015] As a preferred embodiment of the present utility model, the cross arm forms a rectangular rod structure. The cross arm can be turned over and stored in front of the cross bar. The connecting seat forms a rectangular block structure, and a mounting hole is provided on the top of the connecting seat.

The support rod can be turned over and stored on the back of the pull rod. The cross bar is fixedly provided with an ear plate. The support rod can be rotated to one side of the ear plate, and the support rod is locked with the ear plate through a bolt.

[0017] The present utility model provides a wind power generation anemometer tower bracket, which has the following beneficial effects:

[0018] 1. For this wind power generation anemometer tower bracket, the two cross bars can approach each other, and the cross bar and the pull rod can be folded and stored, reducing the occupied space and facilitating storage, carrying, transportation and storage. By setting two reversely rotating support rods, one support rod rotates upward to abut against the top of the upper cross bar, and the other support rod turns downward to abut against the top of the lower cross bar. The support rod is connected to the pull rod through a rivet. When in use, the two support rods are locked with the ear plate through bolts. The pull rod and the two support rods form a cross-shaped support for the two cross bars, thus ensuring the rigidity and stability of the overall structure. The structure is reasonable. By setting a rotatable cross arm, the cross arm is rotatably connected to the fixed block. During the storage stage, the cross arm fits against the front wall of the cross bar. When in use, the cross arm is turned over to the front of the cross bar, and the component for measuring the wind speed can be installed on the connecting seat, which is convenient to use and store.

[0019] 2. For this wind power generation anemometer tower bracket, by rotating the nut, the nut pushes the sliding sleeve downward. The convex rib of the sliding sleeve slides in the limiting groove. When the convex rib enters the thrust groove of the fixed block, the limiting shaft cannot rotate at this time, and thus the angular displacement of the cross arm is locked. When the cross arm needs to be rotated, loosen the nut and lift the sliding sleeve upward, which is simple and flexible to operate. The angle of the cross arm can be adjusted and locked within a certain range. BRIEF DESCRIPTION OF THE DRAWINGS
