The bracket is disposed on the upper surface of the base plate. The bracket includes a base rod and an upright frame. Two sets of base rods are provided. The upright frame is fixed to the upper ends of the two sets of base rods. The lower ends of the two sets of base rods are rotatably connected to the base plate. One end of the support member is rotatably connected to one side of the upright frame. A sliding plate is fixedly connected to one end of the upper surface of the base plate at the opposite end of the bracket. The length direction of the sliding plate is the same as the length direction of the base plate. The other end of the support member is slidably connected to the sliding plate. The clamping assembly is disposed at the end of the sliding plate near the bracket.

[0006] Preferably, the slide is provided in two sets, the two sets of slides are symmetrically arranged and spaced apart, and the side of the slide is provided with a through groove.

[0007] Preferably, one end of the support member is fixedly connected to a connecting frame, and the support member is rotatably connected to the upright frame through the connecting frame. The other end of the support member is threadedly connected to a threaded rod, and the free end of the threaded rod is fixedly connected to a horizontal threaded rod.

[0008] Preferably, the threaded rod is located in the gap between the two sets of sliding plates, the length direction of the transverse screw is perpendicular to the length direction of the threaded rod, and the two ends of the transverse screw are slidably connected to the grooves of the two sliding plates respectively.

[0009] Preferably, an external clamping nut is threaded onto the outer circumferential side of the threaded rod, and the two external clamping nuts respectively clamp the outer sides of the two sets of sliding plates.

[0010] Preferably, the stabilizing assembly includes a front clamping plate and a rear clamping plate. The front clamping plate is attached to the end face of the slide plate near the bracket, and the rear clamping plate is disposed on the side of the front clamping plate away from the bracket. The rear clamping plate is inserted through the grooves of the two sets of slide plates. Both ends of the front clamping plate are fixedly connected to a front semi-cylinder, and the two front semi-cylinders are respectively located on the outer sides of the two sets of slide plates. Both ends of the rear clamping plate are fixedly connected to a rear semi-cylinder, and the two rear semi-cylinders are respectively located on the outer sides of the two sets of slide plates.

[0011] Preferably, the clamping assembly further includes a fastening nut, the front half-cylinder and the rear half-cylinder are coaxially arranged, the open end face of the front half-cylinder located on the same side is in contact with the open end face of the rear half-cylinder, the fastening nut is sleeved on the outer periphery of the front half-cylinder and the rear half-cylinder, and the fastening nut is threadedly connected to the front half-cylinder and the rear half-cylinder.

[0012] Preferably, an inner extension plate is fixedly connected to the side of the front clamping plate, and the inner extension plate is located in the gap between the two sets of sliding plates.

First, remove the fastening nuts, take out the front and rear clamping plates of the stabilizing assembly, loosen the outer clamping nuts to release the clamp on the horizontal threaded rod, and pull the threaded rod to make the horizontal threaded rod slide in the groove of the sliding plate. Then, push the support component. Since the horizontal threaded rod can slide in the groove of the sliding plate, and the support component is rotatably connected to the upright frame and the base rod is rotatably connected to the base plate, the movement of the support component causes the upright frame and base rod to slowly tilt around the rotation axis on the base plate, gradually lowering the weather mast from a vertical working state to a maintenance-ready state. After the weather mast is lowered, maintenance personnel can safely repair and maintain equipment such as lightning rods and wind sensors from the ground without having to climb to heights, avoiding the dangers of climbing to heights in inclement weather conditions.

[0016] 2. After maintenance, reverse the operation, move the horizontal screw to abut against the end of the slide groove of the slide plate near the support, so that the weather mast is slowly raised to a vertical position. Adjust the angle, then rotate the outer clamping nut to fix the support to the slide plate through the horizontal screw. Insert the inner extension plate of the front clamp into the gap between the two sets of slide plates, with the side of the front clamp against the end face of the slide plate. Insert the rear clamp through into the slide groove of the two sets of slide plates, so that the front half-cylinder of the front clamp and the rear half-cylinder of the rear clamp on the same side are respectively fitted onto the outer periphery of the horizontal screw on the same side. Fit the fastening nut on the outer periphery of the front half-cylinder and the rear half-cylinder, and tighten the fastening nut to make the front clamp and the rear clamp tightly clamped on the slide plate, ensuring that the weather mast is firmly fixed and restored to normal working condition.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] This utility model provides a wind turbine meteorological mast that is easy to maintain, such as Figure 1 and Figure 2 As shown, the system includes a base plate 1, a bracket 2, a support member 3, and a clamping assembly 6. The bracket 2 is mounted on the upper surface of the base plate 1. The bracket 2 includes base rods 21 and uprights 22. Two sets of base rods 21 are provided. The uprights 22 are fixed to the upper ends of the two sets of base rods 21. The lower ends of the two sets of base rods 21 are rotatably connected to the base plate 1, allowing the base rods 21 to rotate relative to the base plate 1, thereby tilting the uprights 22 at a certain angle. This rotatable connection design makes subsequent lowering and maintenance of the meteorological mast possible. One end of the support member 3 is rotatably connected to one side of the uprights 22, as shown... Figure 7As shown, a sliding plate 5 is fixedly connected to one end of the upper surface of the base plate 1 at the opposite end of the support 2. There are two sets of sliding plates 5, which are symmetrically arranged and spaced apart, providing space for the installation and movement of the threaded rod 4 and the horizontal screw 41. A groove 51 is opened through the side of the sliding plate 5. The length direction of the sliding plate 5 is the same as the length direction of the base plate 1. The other end of the support member 3 is slidably connected to the sliding plate 5. A connecting frame 31 is fixedly connected to one end of the support member 3. The support member 3 is rotatably connected to the upright 22 through the connecting frame 31. A threaded rod 4 is threadedly connected to the other end of the support member 3. Rotating the threaded rod 4 can adjust the length of the threaded rod 4 extending out of the support member 3, thereby changing the total length of the support member 3 and the threaded rod 4. A horizontal screw 41 is fixedly connected to the free end of the threaded rod 4. The threaded rod 4 is located in the gap between the two sets of slide plates 5. The length direction of the horizontal screw 41 is perpendicular to the length direction of the threaded rod 4. The two ends of the horizontal screw 41 are slidably connected to the grooves 51 of the two slide plates 5. The outer periphery of the threaded rod 4 is threaded with an external clamping nut 42, which clamps the outer sides of the two sets of slide plates 5 respectively. When it is necessary to adjust the angle of the meteorological mast or to perform maintenance, the stabilizing assembly 6 is removed, and the threaded rod 4 is pulled by loosening the external clamping nuts 42, thereby causing the horizontal screw 41 to slide in the groove 51 of the slide plate 5. Since one end of the support member 3 is rotatably connected to the upright 22 and the other end is slidably connected to the slide plate 5 through the horizontal screw 41, the sliding of the horizontal screw 41 will push the support member 3 to move, thereby causing the upright 22 and the base rod 21 to rotate around the rotation axis on the base plate 1, realizing the tilting of the meteorological mast. This structural design makes the angle adjustment of the meteorological mast more convenient and flexible, eliminating the need for maintenance personnel to climb to heights and allowing operation from the ground, greatly improving the safety and convenience of maintenance.

[0028] like Figure 3 and Figure 4 As shown, the stabilizing assembly 6 is located at one end of the slide plate 5 near the bracket 2, as... Figure 5 and Figure 6As shown, the clamping assembly 6 includes a front clamping plate 61, a rear clamping plate 62, and a fastening nut 63. The front clamping plate 61 is attached to the end face of the slide plate 5 near the support 2. An inner extension plate 611 is fixedly connected to the side of the front clamping plate 61. The inner extension plate 611 is located in the gap between the two sets of slide plates 5. The rear clamping plate 62 is located on the side of the front clamping plate 61 away from the support 2. The rear clamping plate 62 is inserted through the slide groove 51 of the two sets of slide plates 5. A front semi-cylinder 612 is fixedly connected to both ends of the front clamping plate 61. The two front semi-cylinders 612 are located on the outside of the two sets of slide plates 5, respectively. A rear semi-cylinder 621 is fixedly connected to both ends of the rear clamping plate 62. The two rear semi-cylinders 621 are located on the outside of the two sets of slide plates 5, respectively. The front semi-cylinder 612 and the rear semi-cylinder 621 are coaxially arranged, with the open end face of the front semi-cylinder 612 and the open end face of the rear semi-cylinder 621 fitting together on the same side. A fastening nut 63 is fitted onto the outer circumference of both the front semi-cylinder 612 and the rear semi-cylinder 621, and both the fastening nut 63 and the front semi-cylinder 612 and the rear semi-cylinder 621 are threaded together. An inner extension plate 611 is fixedly connected to the side of the front clamping plate 61, and the inner extension plate 611 is located in the gap between the two sets of sliding plates 5. When the horizontal screw 41 abuts against the end of the slide groove 51 of the slide plate 5 near the support 2, the weather mast is in a vertical position. Tighten the fastening nuts 63 on both sides of the slide plate 5, so that the two sets of fastening nuts 63 are clamped on both sides of the two sets of slide plates 5, and the horizontal screw 41 is initially fixed. Insert the inner extension plate 611 of the front clamping plate 61 into the gap between the two sets of slide plates 5, with the side of the front clamping plate 61 against the end face of the slide plate 5. Insert the rear clamping plate 62 through and into the slide groove 51 of the two sets of slide plates 5, so that... The front semi-cylinder 612 of the front clamping plate 61 and the rear semi-cylinder 621 of the rear clamping plate 62 are respectively fitted onto the outer periphery of the horizontal threaded rod 41 on the same side. The fastening nut 63 is fitted onto the outer periphery of the front semi-cylinder 612 and the rear semi-cylinder 621, and tightened to secure the front clamping plate 61 and the rear clamping plate 62 tightly onto the sliding plate 5, further fixing the position of the support member 3 and ensuring that the meteorological mast remains stable during operation, preventing swaying or displacement due to wind or other factors. This design of the stabilizing assembly 6 effectively improves the stability of the meteorological mast, ensuring its normal operation under various severe weather conditions.

[0029] like Figure 8 As shown, when the horizontal screw 41 abuts against the end of the slide groove 51 of the slide plate 5 away from the support 2, the wind turbine meteorological mast is in a state of waiting for maintenance, and the support 2 is in a tilted and fallen state.

[0030] like Figure 1 and Figure 2As shown, a lightning rod 7 is fixedly connected to the upper end of the support frame 22. A wind sensor 8 is installed on one side of the lightning rod 7 and mounted on the support frame 22. The support frame 22 can stably support the lightning rod 7, wind sensor 8, and other equipment. The fixed connection of the lightning rod 7 to the upper end of the support frame 22 can effectively prevent the meteorological mast from being struck by lightning, protecting the safety of internal equipment and maintenance personnel. The wind sensor 8 installed on one side is used to monitor meteorological data such as wind speed and wind direction in real time, providing critical information for the operation of the wind turbine.

[0031] Using this utility model, such as Figure 1 and Figure 2 As shown, when the wind turbine meteorological mast needs maintenance, the maintenance personnel operate from the ground. First, they remove the fastening nut 63, take out the front clamping plate 61 and rear clamping plate 62 of the clamping assembly 6, loosen the outer clamping nut 42 to release the clamp on the horizontal screw 41, and pull the threaded rod 4, thereby causing the horizontal screw 41 to slide in the groove 51 of the sliding plate 5. Then, they push the support member 3. Since the horizontal screw 41 can slide in the groove 51 of the sliding plate 5, and the support member 3 is rotatably connected to the upright frame 22 and the bottom rod 21 is rotatably connected to the base plate 1, the movement of the support member 3 causes the upright frame 22 and the bottom rod 21 to slowly tilt around the rotation axis on the base plate 1, so that the meteorological mast is gradually lowered from the vertical working state to the maintenance-ready state. After the meteorological mast is lowered, the maintenance personnel can safely perform maintenance and upkeep on the lightning rod 7, wind sensor 8, and other equipment from the ground without having to climb to a height, avoiding the dangers of climbing to a height in severe weather conditions. After maintenance, reverse the operation, move the horizontal screw 41 to abut against the end of the slide groove 51 of the slide plate 5 near the bracket 2, so that the weather mast is slowly raised to a vertical position. Adjust the angle, then rotate the outer clamping nut 42 to fix the support 3 to the slide plate 5 through the horizontal screw 41. Insert the inner extension plate 611 of the front clamp 61 into the gap between the two sets of slide plates 5, with the side of the front clamp 61 against the end face of the slide plate 5. Insert the rear clamp 62 through into the slide groove 51 of the two sets of slide plates 5, so that the front semi-cylinder 612 of the front clamp 61 and the rear semi-cylinder 621 of the rear clamp 62 on the same side are respectively fitted onto the outer periphery of the horizontal screw 41 on the same side. Fit the fastening nut 63 onto the outer periphery of the front semi-cylinder 612 and the rear semi-cylinder 621, and tighten the fastening nut 63 to make the front clamp 61 and the rear clamp 62 tightly clamp onto the slide plate 5, ensuring that the weather mast is firmly fixed and restored to normal working condition.

[0032] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
