Utility Model Content

[0005] In order to alleviate the problems of complex structure and low flexibility of use of existing wind detection devices, the present application provides a wind measuring instrument.

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The embodiment of the present application discloses a wind measuring instrument.

[0033] Example 1

[0034] Reference Figure 1 A wind force measuring instrument includes a support seat 100, and the support seat 100 includes a base 110. A vertically arranged support rod 120 is installed on the base 110. A wind deflector 200 is fixedly connected to the support rod 120. The wind deflector 200 is parallel to the support rod 120, and one end of the wind deflector 200 is tapered to serve as the windward end. A movable rod 300 is hinged on the wind deflector 200. The hinge axis of the movable rod 300 and the wind deflector 200 is perpendicular to the plane where the wind deflector 200 is located. The end of the movable rod 300 away from the wind deflector 200 is fixedly connected to a windward plate 310. The windward plate 310 is arranged perpendicular to the wind deflector 200. The movable rod 300 falls freely under the gravity of itself and the windward plate 310. Scale lines are arranged on the wind deflector 200. The scale lines are arranged in an arc shape with the hinge axis of the movable rod 300 as the center. In windy weather, the wind direction plate 200 is turned toward the direction of the strong wind, and the windward plate 310 will drive the movable rod 300 to rotate under the action of wind force. The rotation angle of the movable rod 300 can be read through the scale line, and then the wind force can be obtained according to the rotation angle of the movable rod 300. The wind force measuring instrument has a simple structure, a simple and convenient measurement method, and a wide range of applicability.

[0035] The implementation principle of a wind force measuring instrument in an embodiment of the present application is: the windward plate 310 is supported by a support rod 120 and a wind direction plate 200. In windy weather, the wind blows the windward plate 310, and the windward plate 310 and the movable rod 300 will rotate under the push of the wind force. Then the staff can calculate the size of the wind force according to the rotation angle of the movable rod 300 to realize wind force detection. The wind force measuring instrument has a simple structure and higher flexibility in use.

[0036] Example 2

[0037] Reference Figure 2 and Figure 3 , the difference between this embodiment and embodiment 1 is that: in order to facilitate the adjustment of the angle of the wind deflector 200, the support rod 120 is rotatably connected to the base 110, the support rod 120 rotates along its own axis, and an adjusting member 130 is installed on the base 110, and the adjusting member 130 includes a worm 131 rotatably connected to the inside of the base 110, and a worm wheel 132 is coaxially fixedly connected to the support rod 120, and the worm 131 is meshed with the worm wheel 132. When the wind direction changes, the staff rotates the worm 131 to drive the worm wheel 132 to rotate, which can drive the support rod 120 to rotate, and then drive the wind deflector 200 to adjust the angle of the wind deflector 200. At the same time, the self-locking ability of the worm wheel 132 and the worm 131 is used to prevent the wind deflector 200 from rotating under the action of wind force, thereby ensuring the stability of the wind deflector 200 during use.

[0038] Reference Figure 2 and Figure 5 The movable rod 300 is hinged to the wind deflector 200 through a hinge rod, the movable rod 300 is fixedly connected to the hinge rod, the hinge rod is rotatably connected to the wind deflector 200, and the hinge rod is coaxially fixedly connected to the ratchet 500. The wind deflector 200 is slidably connected to a moving block 520, which slides in a direction perpendicular to the wind deflector 200, and the moving block 520 is rotatably connected to a ratchet 510, which is located above the ratchet 500 and is clamped on the ratchet 500 under the action of its own gravity.

[0039] Reference Figure 4 and Figure 5 In order to facilitate the control of the position of the pawl 510, a pusher 530 is installed on the wind deflector 200. The pusher 530 includes a bracket 531 fixedly connected to the wind deflector 200. The bracket 531 is provided with a screw 532. The screw 532 is threadedly connected to the bracket 531. The screw 532 passes through the bracket 531 and is slidably connected to the moving block 520. When the wind blows, the moving rod 300 rotates and the ratchet 500 is driven to rotate at the same time. Under the obstruction of the pawl 510, the ratchet 500 is difficult to rotate, so that the moving rod 300 can be kept at the maximum rotation range, so that the maximum wind force can be measured, and the accuracy of the maximum wind force value measurement is improved. After the measurement is completed, the screw 532 is rotated to drive the moving block 520 to slide, and then the pawl 510 is driven to move to one side of the ratchet 500, so that the ratchet 500 can automatically rotate and reset, and wait for the next wind force measurement.

[0040] The implementation principle of a wind force measuring instrument in an embodiment of the present application is as follows: by rotatably connecting the support rod 120 to the base 110, when in use, the staff rotates the worm 131 according to the actual wind direction, and adjusts the direction of the wind deflector 200 through the cooperation of the worm 131 and the worm wheel 132; at the same time, the rotation of the moving rod 300 is restricted by the cooperation of the ratchet 500 and the pawl 510, so that the moving rod 300 can remain stable after rotating to the maximum angle, thereby improving the accuracy of the maximum wind force measurement.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
