DETAILED DESCRIPTION

[0028] Common wind direction and anemometers on the market include Figure 1 As shown, it includes a support rod 12, and a wind vane 1, a wind direction wheel 2, a wind cup 3, a wind speed disc 4 and a handle 5 which are arranged on the support rod 12 in sequence.

[0029] The wind vane 1 is connected to the wind vane 2 and can drive the wind vane 2 to rotate. The wind vane 2 is provided with a wind direction scale. The wind angle of the wind vane 1 can be shown on the scale on the wind vane 2, and the wind direction angle can be directly read.

[0030] The wind cup 3 is arranged below the wind direction wheel 2, and the wind cup 3 is connected to the wind speed disk 4. The wind speed disk 4 calculates the wind speed through the rotation of the wind cup 3 and displays it. At present, the wind speed disk 4 on the market is usually an electronic component, which specifically detects the rotation speed of the rotating shaft 11 of the wind cup 3 through a magnetic ring sensor, calculates the wind speed based on the principle that the rotation speed is proportional to the wind speed, and displays it on the wind speed disk.

[0031] Example 1

[0032] like Figures 2 - 7 As shown, the difference between this embodiment and the prior art is the improvement made on the wind speed disc 4.

[0033] The wind speed disc 4 includes a housing 4a, a chassis 4f, a pointer 4g and a transparent cover 4c. The chassis 4f is arranged in the housing 4a, and the chassis 4f is marked with horizontally and vertically equidistant squares. The pointer 4g is arranged at the center of the chassis 4f, and the transparent cover 4c is fixed on the end face of the housing 4a. The transparent cover 4c is rotatably arranged on the end face of the housing 4a.

[0034] Specifically, an annular groove 4b is provided at the edge of the end face of the housing 4a, and a plurality of balls 4d are provided in the annular groove 4b, and the balls 4d are slightly higher than the end face of the housing 4a. A circle of annular grooves 4e are provided on the side of the housing 4a of the wind speed disc 4. The transparent cover 4c is in the shape of a bottle cap, and a protrusion corresponding to the annular groove 4e is provided inwardly at the end of the open end of the transparent cover 4c. The transparent cover 4c is covered on the end face of the wind speed disc 4 and the protrusion is clamped in the annular groove 4e. In this way, the transparent cover 4c can be rotatably clamped on the housing 4a.

[0035] The transparent cover 4c is provided with a 360° scale. In order to reduce the visual difference caused by the height misalignment between the transparent cover 4c and the chassis 4f, the distance between the two should be reduced as much as possible, and the distance between the transparent cover 4c and the pointer 4g is preferably set to 1-2mm. In order to minimize the visual difference, in other embodiments, squares with equal distances horizontally and vertically can be set on the other side of the transparent cover 4c, that is, the squares and the scale are displayed on the two sides of the transparent cover 4c respectively.

[0036] In this embodiment, the pointer 4g is connected to the wind cup 3 through a transmission device. The transmission device includes a first bevel gear 7, a second bevel gear 8, a connecting shaft 9 and a torsion spring 10. The first bevel gear 7 is connected to the rotating shaft 11 of the wind speed disk 4, and the second bevel gear 8 is meshed with the first bevel gear 7. The meshing of the second bevel gear 8 with the first bevel gear 7 can convert the rotation of the wind cup 3 in the horizontal plane direction into the rotation in the vertical plane direction.

[0037] The second bevel gear 8 is connected to one end of the connecting shaft 9, and the other end of the connecting shaft 9 is connected to the pointer. The torsion spring 10 is sleeved on the connecting shaft 9, one end of the torsion spring 10 is connected to the connecting shaft 9, and the other end of the torsion spring 10 is fixed to the housing 4a.

[0038] In this embodiment, the wind force received by the wind cup 3 is converted into the torsion of the torsion spring 10, and the magnitude of the torsion is reflected in the rotation angle of the connecting shaft 9, and the rotation angle of the connecting shaft 9 is reflected in the swing angle of the pointer 4g. Due to the correlation formula between wind force and wind speed, the wind speed can be reflected by the swing angle of the pointer 4g.

[0039] The method of using this embodiment is as follows:

[0040] Assuming that the heading of a ship is 270° and the speed is 8 m / s, after the wind angle is measured to be 220° and the wind speed is 12 m / s through this embodiment, the pointer 4g is returned to its position, and the transparent cover 4c is rotated 270° with the pointer 4g as a reference, and then the number of grids of the chassis 4f is counted from the center position of the transparent cover 4c in the direction of the pointer 4g. When 8 grids are counted, representing 8 m / s, a point is tapped with a pen, namely point A.

[0041] Then rotate the transparent cover 4c 220°, and continue to count the number of grids of the chassis 4f from the center position of the transparent cover 4c in the direction of the pointer 4g. Count to 12 grids, representing 12m / s, and use a pen to mark a point, namely point B.

[0042] Rotate the transparent cover 4c again to make the line connecting points A and B parallel to the pointer 4g, and follow the rule that A is on top and B is on the bottom. Read the scale number on the scale of the transparent cover 4c pointed by the pointer 4g as 176°, that is, the true wind direction is 176°, and read the number of grids between A and B as 9.8 grids, that is, the true wind speed is 9.8 m / s.

[0043] Preferably, the present embodiment further provides a blind hole at the end of the handle 5 along the length direction of the handle 5, and an internal thread is provided at the opening of the blind hole. A paintbrush 6 is also included, and the tip of the paintbrush 6 is inserted into the blind hole, and an external thread corresponding to the internal thread is provided on the paintbrush 6. In this way, there is no need to prepare a paintbrush separately when sailing outside.

[0044] Furthermore, in this embodiment, a sponge is provided at the other end of the paintbrush 6 to erase the handwriting on the transparent cover 4c for the convenience of the next measurement.

[0045] Furthermore, the sponge is in a cubic shape, which is convenient for rotating and unscrewing the paintbrush 6 .

[0046] Furthermore, it also includes a pen eraser cover, which is arranged on the pen eraser and can protect the pen eraser from external pollution.

[0047] In this embodiment, the scale on the transparent cover 4c can be used to read the measured wind speed and can also be used to calculate the real wind direction and wind speed. One object has multiple uses and an ingenious structure.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
