Description

Technical Field

[0001] This application relates to the field of anemometer technology, and more specifically to an anemometer. Background Technology

[0002] An anemometer is an instrument specifically designed to measure the speed of airflow.

[0003] A current anemometer (CN208283421U) includes a base with a support fixedly mounted on top. A transmission rod is movably mounted above the support, and a bearing is located at the connection between the support and the transmission rod. The transmission rod has three connecting rods; one end of each connecting rod is fixedly connected to the outer circumference of the transmission rod, and the other end is fixedly connected to a wind cup. The openings of the wind cups are arranged in one direction. The transmission rod has an anti-freezing part. It should be noted that by providing the anti-freezing part on the transmission rod, rain and snow falling from above are blocked from reaching the bearing, reducing the risk of the bearing freezing. However: [The following text appears to be a separate, unrelated section:] From the accompanying drawings in its specification... Figure 1 As can be seen, the antifreeze part is a cover, and the distance between the cover and the bearing at the connection between the support and the transmission rod is relatively large. This makes it easy for rain and snow to fall onto the bearing surface when they drift at an angle, which may cause the bearing to freeze or reduce the smoothness of its rotation, thus affecting the test results.

[0004] Therefore, there is a need for an antifreeze anemometer that effectively prevents external rain and snow from falling onto the bearing. Summary of the Invention

[0005] The main objective of this application is to provide an anemometer, comprising a base, a rotating shaft, multiple air-collecting components, and an anti-freeze component. The base has a receiving groove in which a bearing is embedded. One end of the rotating shaft is connected to the inner ring of the bearing. Each air-collecting component includes a connecting rod and a wind cup. Both ends of each connecting rod are fixedly connected to the end of the rotating shaft away from the bearing and the corresponding wind cup, respectively. The anti-freeze component includes a first anti-freeze cover and a second anti-freeze cover. The first anti-freeze cover has a central hole and is connected to the base, covering the bearing. The rotating shaft passes through the central hole. The second anti-freeze cover is connected to the rotating shaft and rotates synchronously with it. The end of the first anti-freeze cover away from the base has a reduced diameter section, which is covered by the second anti-freeze cover. By covering the bearing with the first anti-freeze cover and the annular channel between the central hole wall and the side wall of the rotating shaft with the second anti-freeze cover, this method effectively prevents external rain and snow from falling onto the bearing and provides anti-freezing advantages compared to existing technologies.

[0006] Another objective of this application is to provide an anemometer in which the radial dimension of the second antifreeze cover gradually increases from one end away from the base to the other end. The reduced diameter portion includes a vertical arc surface and a contoured surface. The contoured surface is located at the end of the vertical arc surface away from the base. The end of the second antifreeze cover near the base extends to the vertical arc surface, and a contoured channel is provided between the inner wall of the second antifreeze cover and the contoured surface. The risk of rain and snow entering is further reduced by arranging the contoured channel at an angle.

[0021] Indicative anemometer, for reference Figures 1 to 2 A preferred embodiment of the present invention provides an anemometer comprising a base 10, a rotating shaft 20, multiple air collecting components 30, and an antifreeze component 40.

[0022] Specifically, the base 10 has a receiving groove 101, in which a bearing 1011 is embedded; in addition, one end of the rotating shaft 20 is connected to the inner ring of the bearing 1011; furthermore, each of the air collecting components 30 includes a connecting rod 301 and a fan cup 302, with both ends of each connecting rod 301 fixedly connected to the end of the rotating shaft 20 away from the bearing 1011 and the corresponding fan cup 302, respectively; furthermore, the antifreeze component 40 includes a first antifreeze cover 401 and a second antifreeze cover 402. 02. The first antifreeze cover 401 has a central hole 4011. The first antifreeze cover 401 is connected to the base 10 and covers the bearing 1011. The connection method is preferably screw connection. The rotating shaft 20 passes through the central hole 4011. The second antifreeze cover 402 is connected to the rotating shaft 20 and rotates synchronously with the rotating shaft 20. The end of the first antifreeze cover 401 away from the base 10 has a reduced diameter portion 4012. The second antifreeze cover 402 covers the reduced diameter portion 4012.

[0023] It should be noted that by setting the first antifreeze cover 401 to cover the bearing 1011, external rain and snow can only fall into the bearing 1011 through the annular channel between the hole wall of the central hole 4011 and the side wall of the rotating shaft 20. Since the cross-sectional area of ​​the annular channel is small, the risk of rain and snow falling into the bearing 1011 is effectively reduced. In addition, by setting the second antifreeze cover 402 above the first antifreeze cover 401 and covering the top of the first antifreeze cover 401 in the height direction, the external rain and snow that originally fell into the bearing 1011 through the annular channel between the hole wall of the central hole 4011 and the side wall of the rotating shaft 20 is blocked by the second antifreeze cover 402, making it more difficult for them to fall into the bearing 1011 and freeze. Furthermore, since the second antifreeze cover 402 is fixedly connected to the rotating shaft 20, when the rotating shaft 20 rotates, the rain and snow falling on the second antifreeze cover 402 will also be subject to centrifugal force and drift outward. It is evident that, compared to existing technologies, this application has the advantages of effectively preventing external rain and snow from falling onto the bearing and preventing freezing.

[0024] Furthermore, in this application, the radial dimension of the second antifreeze cover 402 gradually increases from one end away from the base 10 to the other end. The reduced diameter portion 4012 includes a vertical arc surface 40121 and a contoured surface 40122. The contoured surface 40122 is located at the end of the vertical arc surface 40121 away from the base 10. The end of the second antifreeze cover 402 near the base 10 extends to the vertical arc surface 40121, and a contoured channel 403 is provided between the inner wall of the second antifreeze cover 402 and the contoured surface 40122.

[0025] It should be noted that the contoured channel 403 is arranged at an angle, making it difficult for rain and snow to pass through the contoured channel 403 and enter the annular channel between the hole wall of the central hole 4011 and the side wall of the rotating shaft 20; in addition, since the outer side wall of the second antifreeze cover 402 is a conical surface, external rain and snow can easily slide off along the conical surface.

[0026] Furthermore, the first antifreeze cover 401 has a stepped hole 4013 and a temporary storage ring cavity 4014 at one end near the base 10. Two semi-circular baffles 201 are sleeved on the rotating shaft 20. The two semi-circular baffles 201 are fixedly connected to the rotating shaft 20 and spliced ​​together to form a disc. The disc is close to the connection between the hole 4013 and the central hole 4011, and the outer periphery of the disc is located above the temporary storage ring cavity 4014. This ensures that even if a small amount of rain or snow falls into the annular channel between the hole wall of the central hole 4011 and the side wall of the rotating shaft 20, it will fall onto the disc and be thrown outward under centrifugal force, entering the temporary storage ring cavity 4014, and is unlikely to fall onto the bearing 1011, thus further improving the anti-freezing effect of the bearing 1011 of the anemometer.

[0027] Furthermore, in this application, the rotating shaft 20 has a hollow channel 202, which extends from one end face of the rotating shaft 20 near the base 10 to the other end. The anemometer also includes a heating element 50, one end of which is fixedly mounted on the base 10, and the other end of which extends into the hollow channel 202.

[0028] It should be noted that by setting the heating element 50, a certain amount of heat is applied to the wind cup 302, which effectively prevents rain and snow from accumulating in the cavity of the wind cup 302, thereby reducing the cavity volume of the wind cup 302 and affecting the test results. The heating element 50 is preferably a heating rod, and the heating rod can only be heated at the top.

[0029] Furthermore, in order to support the rotating shaft 20 and reduce friction, and to provide a placement space for the heating element 50, the bottom wall of the receiving groove 101 also has a support groove 1012. A ball bearing 1013 is rolled between the end of the rotating shaft 20 near the base 10 and the support groove 1012. The ball bearing 1013 is located on the outside of the heating element 50.

[0030] Furthermore, to restrict the movement of the ball 1013 along the radial direction of the rotating shaft 20, the rotating shaft 20 has an annular groove 203 at one end near the ball 1013, and the ball 1013 extends into the annular groove 203.

[0031] Furthermore, in order to improve the heating effect of the heating element 50 on the wind cup 302, a heat-conducting rod 3011 is provided inside each of the connecting rods 301. The heat-conducting rod 3011 is fixedly connected to the connecting rod 301. The fixed connection method includes, but is not limited to, welding. The two ends of the heat-conducting rod 3011 extend to the hollow channel 202 and the wind cup 302, respectively.

[0032] Furthermore, the anemometer also includes a temperature and humidity sensor 601, a battery 602, and a controller 603. The temperature and humidity sensor 601 is fixedly mounted on the base 10, the controller 603 is electrically connected to the battery 602, and both the temperature and humidity sensor 601 and the heating element 50 are electrically connected to the controller 603.

[0033] It should be noted that by setting the temperature and humidity sensor 601, conditions are provided for the heating element 50 when there is a possibility of icing outside, and by setting the battery 602, conditions are provided for the power supply of the controller 603 and the heating element 50.

[0034] Furthermore, for placing the battery 602, the base 10 has an open receiving cavity 102, in which the battery 602 and the controller 603 are both placed. The anemometer also includes a plug that blocks the opening of the receiving cavity 102.

[0035] In summary, the anemometer described in the embodiments of this application is explained, which provides advantages such as effectively preventing external rain and snow from falling on the bearing and preventing freezing.

[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
