Background

A wind vane is a device that measures the direction of the wind. Is basically an asymmetrically shaped object with the center of gravity point fixed on the vertical axis. Or a cloth structure in the shape of a trumpet. When wind blows, the end which generates larger resistance to the air flow can rotate along the wind, and the wind direction is displayed. The method is widely applied to the industries of meteorology, chemical industry, mining area, agriculture, oil field exploration and the like.

The wind vane is generally installed at a higher position, and the height of surrounding structures is mainly considered during installation so as not to be shielded by the surrounding structures as an installation reference. In the chemical production place, the wind vane is generally installed at the top of structure, and under the higher condition of structure, dismantlement and installation all need climb to the structure top, produce danger promptly and be difficult for the installation again, and cloth matter wind vane damages easily. It is therefore desirable to provide a weathervane device that is easy to remove and install, and that is durable.

And a plurality of groups of leading rope limiting devices are fixedly arranged on the vertical rod, the leading rope limiting devices are circular rings, and the leading ropes can freely rise and fall in the circular rings.

Wherein, the guide rope fixing device is also a circular ring.

Wherein the bottom of the sleeve is closed.

And a limit baffle is further arranged at the upper end of the sleeve.

Further, the sleeve is a thin-walled tube.

Wherein the height of the vertical rod is greater than that of the structure.

Wherein, the wind vane is a cloth wind vane.

Furthermore, a metal wind vane is arranged between the cloth wind vane and the sleeve.

Preferably, the two groups of the guide rope limiting devices are provided.

The utility model discloses a liftable wind vane device has following advantage: due to the liftable structural design, the wind vane can be detached and installed without climbing to the top of a structure; the double wind vanes are arranged, so that the whole device is higher in reliability and more durable.

Drawings

Fig. 1 is the structure schematic diagram of the liftable wind vane device of the utility model.

Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.

As shown in fig. 1, the liftable wind vane device of the present embodiment includes a cloth wind vane 1, a metal wind vane 2, a limit baffle 3, a sleeve 4, a rope guide limit device 5, a guide rope 6, a rope guide fixing device 7, a pulley 8, and a vertical rod 9.

The vertical rods 9 are vertically fixed on the side surfaces of the structures 10, the diameter of each vertical rod 9 can be 4 minutes or 6 minutes, the height of each vertical rod 9 is determined according to the height of the structures 10, and the height of each vertical rod is 1.5-2 meters higher than the height of the structures 10. In order to avoid that the stability of the device is influenced by too much wind, the vertical rods 9 need to be tightly attached to the side wall of the structure 10.

The pulley 8 is fixedly arranged at the top of the vertical rod 9, one end of the guide rope 6 bypasses the pulley 8, the sleeve 4 is fixed on the guide rope 6 along the vertical direction, and the sleeve 4 can move up and down along the vertical rod 9 under the traction of the guide rope 6 and the pulley 8. The bottom of the cloth vane 1 is arranged in a sleeve 4, and the cloth vane can freely rotate along with the wind direction in the sleeve 4. Wherein the bottom of the sleeve 4 is closed.

And a limit baffle 3 is further arranged at the upper end of the sleeve 4 to prevent the wind vane from moving up and down in the sleeve 4. Because cloth matter wind vane 1 is easy to damage, further be provided with metal wind vane 2 below cloth matter wind vane 1 side by side, guarantee the normal use of whole wind vane device when cloth matter wind vane 1 damages.

Further, a plurality of groups of leading rope limiting devices 5 are fixedly arranged on the vertical rod 9, each leading rope limiting device 5 is a circular ring, and the leading ropes 6 can freely lift in the circular rings, so that the stability of the leading ropes 6 when wind power is too large is guaranteed. The bottom of the vertical rod 9 is provided with a leading rope fixing device 7, and two ends of the leading rope 6 can be fixed at the bottom of the vertical rod 9. Preferably, the number of the rope guiding limiting devices 5 is two, and the two groups of the rope guiding limiting devices are respectively arranged on the trisection point of the vertical rod 9.

Further, the leader fixing device 7 is also a circular ring, and both ends of the leader 6 are tied to the leader fixing device 7 to be fixed.

Further, the sleeve 4 is a thin-walled tube to reduce the weight thereof.

The lifting wind vane device of the embodiment can drive the two wind vanes to move up and down along the vertical rod 9 under the traction of the guide rope 6, and the wind vanes can be detached and installed without climbing to the top of a structure; the double wind vanes are arranged, so that the reliability of the whole device is higher.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the principles of the invention, and these changes and modifications should be construed as being included in the scope of the invention.
