Through the arrangement, the clamping structure can realize the positioning and the detachable connection between the body part 41 and the first circuit board 31, so that the guide structure 40 is conveniently detached from the first circuit board 31, and the technical personnel can conveniently check and maintain the first circuit board 31.

Of course, in an alternative embodiment not shown in the drawings, the latching structure may also include a latch 44 disposed on a side of the first circuit board 31 facing the body portion 41 and a latch slot 35 located on the body portion 41, and the latch 44 is in latching engagement with the latch slot 35.

As shown in fig. 3, in the embodiment of the present invention, the wind meter 100 further includes a fixing member 110 for fixing the second circuit board 21, the fixing member 110 is located in the mounting cavity 101, and the fixing member 110 is connected to the circumferential side wall 11.

Through the above arrangement, the second circuit board 21 can be fixed on the fixing member 110, that is, the second circuit board 21 can be fixed in the mounting cavity 101, so that the second circuit board 21 is fixedly mounted, and under the action of the floating assembly 50, the first circuit board 31 moves in the direction away from the second circuit board 21 along the first direction, so that the temperature measuring members 33 can be in uniform contact with the bottom wall 12, and the accuracy of the detection assembly 30 in detecting the wind speed and the wind direction is improved.

Preferably, in the embodiment of the present invention, the fixing member 110 is a step connected to the circumferential side wall 11, so that the second circuit board 21 can abut against the step surface under the action of an external force, i.e., the second circuit board 21 is fixed on the step surface. Of course, in an alternative embodiment not shown in the drawings, the fixing member 110 may be a plurality of ribs arranged at intervals in the circumferential direction, as long as the second circuit board 21 can be supported.

As shown in FIG. 7, an embodiment of the present invention provides a weather station. The weather station includes a mounting bracket 60, a housing 80 provided to the mounting bracket 60, a rain gauge 70 provided in the housing 80, and the above-described wind meter 100 connected to the housing 80. Through the setting, the weather station not only can detect wind speed and wind direction, but also can detect precipitation, thereby increasing the function of the weather station.

Specifically, in the embodiment of the present invention, the rain gauge 70 is in control connection with the controller 90 to feed back a signal detected by the rain gauge 70 to the controller 90.

Preferably, in the embodiment of the present invention, the housing 80 includes an upper case and a lower case connected to the upper case, the anemometer 100 is disposed on the upper case, and the rain gauge 70 is disposed on the upper case.

As shown in FIGS. 8 and 9, in an embodiment of the invention, the weather station further includes a mounting member 13, the housing 80 has a mounting slot 81, and the mounting member 13 includes a mounting body 131 and a sleeve 132. Wherein, at least part of the installation body 131 is positioned in the installation groove 81, and the installation body 131 is connected with the shell 80; the sleeve 132 is connected to the mounting body 131, at least a part of the sleeve 132 is located in the mounting cavity 101, and an end of the sleeve 132 away from the mounting body 131 abuts against the second circuit board 21.

With the above arrangement, the wind meter 100 can be mounted to the housing 80 via the mounting member 13, and the sleeve 132 can press the second circuit board 21 against the fixing member 110, so that the plurality of temperature measuring members 33 and the heating member 32 on the first circuit board 31 can be brought into better contact with the bottom wall 12.

From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects: through setting up the subassembly that floats that can make temperature measurement piece remove along first direction, a plurality of temperature measurement pieces can contact with the diapire under the effect of subassembly that floats, like this, when a plurality of temperature measurement pieces detected the temperature of the different positions of diapire, the subassembly that floats can make the temperature on the different positions of diapire evenly transmit to a plurality of temperature measurement pieces on to improve the accuracy that a plurality of temperature measurement pieces detected the temperature of a plurality of positions of diapire, and then can improve the accuracy that the anemoscope detected wind direction and wind speed.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
