[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] The utility model is a multi-directional wind energy collection device capable of automatically adjusting with wind direction, comprising a base 1, a middle connecting structure assembly 2, a fluid vortex 3, a connecting rod 4, a tail wing plate 5 and a piezoelectric ceramic sheet 6, wherein the upper end of the base 1 is raised to form a protrusion 10.

[0025] The middle connecting structure assembly 2 includes a cylindrical sleeve 2-1 located at the rear and a conical sleeve 2-2 located at the front. The interiors of the cylindrical sleeve 2-1 and the conical sleeve 2-2 are interconnected. Both ends of the cylindrical sleeve 2-1 and the conical sleeve 2-2 in the front-to-back direction are open. The rear end of the cylindrical sleeve 2-1 is connected with a rib plate 2-4, which divides the rear end of the cylindrical sleeve 2-1 into two areas. A columnar connector 2-3 is connected to the lower wall of the cylindrical sleeve 2-1, and the lower end of the columnar connector 2-3 is recessed to form a receiving portion 2-5.

[0026] The flow body 3 includes a connected flow cylinder 3-1 and a flow plate 3-2, the flow body 3 is installed in the inner space of the cylindrical sleeve 2-1 and the conical sleeve 2-2, and the end of the flow plate 3-2 away from the flow cylinder 3-1 is connected to the rib 2-4. The flow cylinder 3-1 is a hollow cylinder.

[0027] The upper end of the base 1 is convexly formed with a protrusion 10, on which a bearing (not shown) is installed. The position above the receiving portion 2-5 on the cylindrical connector 2-3 is concavely formed with a groove 2-6. When the base 1 is connected to the cylindrical connector 2-3, the base 1 is installed in the receiving portion 2-5, and the protrusion 10 with the bearing is just located in the groove 2-6. At this time, the cylindrical connector 2-3 is coaxial with the base 1 and can rotate freely. The lower end of the base 1 is connected to a ground fixing device (not shown).

[0028] The connecting rod 4 is connected to the rib plate 2-4, and the connecting rod 4 and the flow-circling plate 3-2 are respectively connected to the two opposite sides of the rib plate 2-4. The end of the connecting rod 4 away from the rib plate 2-4 is connected with a tail plate 5.

[0029] The piezoelectric ceramic sheets 6 are adhered to the two side surfaces of the bypass plate 3-2 adjacent to the ends of the ribs 2-4.

[0030] In the present invention, the materials of the middle connecting structure assembly 2, the vortex body 3, the tail wing plate 5 and the connecting rod 4 are all polyvinyl chloride (PVC). The base 1 is a cylinder, and the material of the base 1 is polyvinyl chloride (PVC).

[0031] As a specific embodiment of the multi-directional wind energy collection device of the weather vane of the utility model, the design dimensions of each structure are as follows: the large circle diameter D1 of the conical sleeve 2-2 is 80mm, the small circle diameter D2 is 36mm, the length L1 is 57mm, and the thickness is 2mm. The front and rear diameters of the cylindrical sleeve 2-1 are D3=36mm and the length L2=35mm. The diameter D4 of the columnar connector 2-3 is 15mm and the thickness is 2mm. The distance between the center of the columnar connector 2-3 and the rib 2-4 is 17.5mm. The width B1 of the connecting rod 4 is 4mm, the length L3 is 170mm, and the height H1 is 10mm. The length L4 of the tail wing plate 5 is 80mm, the width W1 is 65mm, and the thickness is 3mm. The diameter D5 of the base 1 is 13mm. The height H2 of the flow cylinder 3-1 is 36 mm, the diameter D4 is 10 mm, the length L5 of the flow plate 3-2 is 80 mm, the thickness W1 is 1 mm, and the height H3 is 36 mm. The material of the piezoelectric ceramic sheet 6 is a flexible PZT piezoelectric ceramic sheet, with a length L6 of 80 mm, a width W2 of 36 mm, a thickness T3 of 50 μm, and a piezoelectric coefficient D 33 =180×10-12C / N.

[0032] The working principle of the multi-directional wind energy collection device based on the weather vane of the utility model is as follows: the device is placed in a windy environment. When the wind passes through the vortex body 3, according to the vortex shedding effect, the vortex body 3 will undergo vortex shedding. One end of the vortex plate 3-2 is fixed on the rib 2-4, and the piezoelectric ceramic sheet 6 is glued to the two side surfaces of the end of the vortex plate 3-2 adjacent to the rib 2-4 with conductive glue. When the wind in the natural environment passes through the conical sleeve 2-2, the airflow enters the cylindrical sleeve 2-1, and the vibrating spoiler 3-2 causes the piezoelectric ceramic sheet 6 to stretch or compress. The piezoelectric ceramic sheet 6 produces a positive piezoelectric effect (*Q charge = d33*F stress) and then generates a voltage (d33 is a piezoelectric parameter), ultimately achieving the purpose of converting wind energy into electrical energy. It should be noted here that the principle of obtaining electrical energy through piezoelectric ceramic sheets is a common principle in this field and will not be repeated here. At the same time, under the action of wind, the middle connecting structure assembly 2, the connecting rod 4 and the tail wing 5 can rotate around the base 1, so that the device can receive wind energy from multiple directions.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
