Detailed Description

The following describes in further detail embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1 to 5, the wind vane generator comprises a base 1, a vertical rod 2 is arranged on the base 1, a rotatable sleeve 3 is sleeved on the vertical rod 2, a wind vane 4 which is transversely arranged is fixedly connected to the upper end of the sleeve 3, four vertical baffles 5 are arranged outside the sleeve 3, a rectangle which takes the sleeve 3 as the center is enclosed by the four vertical plates, the end parts of two adjacent baffles 5 are hinged to each other, a plurality of telescopic rods 6 which are arranged up and down are arranged at the symmetrical axis of the two adjacent baffles 5, one end of each telescopic rod 6 is connected to the hinged point, and the other end of each telescopic rod 6 is fixedly connected to the outer edge surface of.

For the rotation of better realization sleeve 3, montant 2 and sleeve 3 between install rolling bearing, fixedly connected with is located the dog 7 of sleeve 3 below on montant 2.

In order to realize the installation of the wind vane 4, the wind vane 4 is formed by a transversely-placed vertical plate, the middle part of the vertical plate is superposed with the axis of the sleeve 3, the vertical plate is asymmetrically and fixedly installed at the upper end of the sleeve 3, and the arrow of the wind vane 4 points to the hinge point of one of the two adjacent baffles 5.

In order to realize extension and retraction, the telescopic rod 6 consists of a mandrel and a shell sleeved outside the mandrel, and a pressure spring or a tension spring is connected between the mandrel and the shell. In order to realize the hinge between two adjacent baffles 5 and the connection between the telescopic rod 6 and the hinge point, the hinge point consists of a vertical shaft 8 and a fixing plate 9 which is sleeved on the vertical shaft 8 and can rotate, wherein a plurality of fixing plates 9 are mutually connected on two adjacent baffles 5 in a staggered manner, and one section of the telescopic rod 6 connected with the hinge point is sleeved on the vertical shaft 8 and is positioned between the intervals of the fixing plates 9.

In order to better adapt the baffle 5 to the wind direction, the length of the shell of the telescopic rod 6 which is vertically arranged with the wind vane 4 is smaller than that of the shell of the telescopic rod 6 which is arranged in the same direction with the wind vane 4, namely when the baffle 5 is in a rectangular state, the telescopic rod 6 in the same direction with the wind vane 4 is in a telescopic state, and the telescopic rod 6 which is vertically arranged with the wind vane 4 is in an extended state.

When the device is used, the whole device is firstly placed on a construction site, corresponding warning words are pasted on the baffles 5 or the warning words are directly written on the baffles 5, the baffles 5 are composed of four blocks, so that the multi-direction display purpose can be achieved, when the wind speed in the environment is not very high, when the wind blows the whole device, the sleeve 3 is rotatably connected with the vertical rod 2, and the wind vane 4 is arranged at the upper end of the sleeve 3, so that the wind blows the wind vane 4, the sleeve 3 rotates, the baffles 5 are connected with the sleeve 3 through the telescopic rods 6, the baffle 5 also rotates, the attraction attention is attracted, and the better warning effect is achieved.

When the ambient wind speed is high, the wind vane 4 always points to the wind direction due to the asymmetric installation of the wind vane 4, and meanwhile, the arrow of the wind vane 4 corresponds to the hinge joint between any two adjacent baffles 5, so that the hinge joint points to the wind direction along with the wind vane 4.

Then, because the baffle 5 and the sleeve 3 are connected and supported through the telescopic rods 6, when wind blows to the baffle 5, the baffle 5 cannot keep a rectangular state under the action of wind and is changed into a parallelogram shape, and meanwhile, the long symmetrical axis of the parallelogram can keep the same direction with the wind vane 4, namely the baffles 5 can be turned to be flat, so that the wind resistance is reduced, and further, the wind is prevented from directly blowing to the whole device; meanwhile, because the wind power of natural wind is generally in a continuous conversion state, the force applied to the telescopic rod 6 can be continuously converted, and the plurality of baffles 5 are in a repeated conversion state, so that parallelograms in different forms can be formed, and meanwhile, the conversion can be continuously performed, and therefore, the attention of passers-by and vehicles can be better attracted.

When the wind speed is reduced or no wind exists, the baffles 5 are not stressed by the wind any more, so that the baffles 5 are in a rectangular state again under the action of the telescopic rods 6.

According to the invention, the four vertical baffles 5 form a parallelogram structure, the central point of the parallelogram structure is connected with the central sleeve 3 through the telescopic rods 6, and then the sleeve 3 can rotate along with the wind vane 4 through the design of the wind vane 4, so that the long symmetrical axis of the parallelogram structure is opposite to the wind direction when the sleeve rotates, and further under the action of wind, the short axis of the parallelogram structure is shorter, thereby greatly reducing wind resistance and avoiding the warning board from being blown down.

The warning board can be displayed at multiple angles by arranging the four baffles 5, so that pedestrians or drivers in all directions can conveniently watch the warning board, and meanwhile, after the warning board is deformed by wind power, the whole device is in a dynamic process under the action of the wind, so that the warning board attracts attention and avoids monotonous arrangement.
