Description

Technical Field

[0001] This utility model belongs to the field of anemometer technology, and in particular relates to a novel cup anemometer. Background Technology

[0002] An anemometer is an instrument used to measure wind speed. It can determine the speed at which air passes through a fixed area per unit time. By measuring wind speed, it can be used to monitor the occurrence and development of meteorological disasters such as typhoons, blizzards, and tornadoes.

[0003] When an anemometer is placed outdoors, it is affected by the harsh outdoor low temperature environment. The connection between the shaft and the bearing of the anemometer may freeze, affecting the normal rotation of the anemometer. As a result, the actual measured wind speed value is lower than the normal wind speed value, and the measurement result is inaccurate. Utility Model Content

[0004] To address the above problems, this utility model provides a novel cup anemometer.

[0005] This utility model is implemented as follows: A novel cup-type anemometer includes an end cap. Multiple connecting rods are horizontally and evenly fixed on the outer wall of the end cap. An anemometer cup is fixedly mounted at the end of each connecting rod. A sleeve is vertically fixed at the middle of the lower end of the end cap and connected to a cylindrical column. A cylindrical column is located below the end cap. A shaft is vertically mounted through the central hole of the sleeve. The lower end of the shaft is located within the cylindrical column. A first Teflon bearing is fixedly mounted at the connection point between the lower end wall of the end cap and the shaft. The Teflon bearing has excellent chemical resistance and temperature resistance, ensuring safety and reliability; it also has excellent corrosion resistance and abrasion resistance, providing high protection for mechanical parts while meeting manufacturing and usage requirements; and it has excellent non-adhesive properties, preventing water contact. A groove is formed at the middle of the upper end of the cylindrical column to define the position of a second Teflon bearing. A second Teflon bearing is fixedly installed within the groove. A through hole is formed on the upper wall of the column located at the center of the bottom of the groove. The sleeve passes through the second Teflon bearing and the through hole, and is in close contact with the second Teflon bearing. The sleeve rotates smoothly along the second Teflon bearing. A limit ring is horizontally installed at the upper part of the column and below the sleeve to limit the position of the sleeve, thereby ensuring a reliable connection between the end cap and the column. The outer diameter of the limit ring is larger than the diameter of the through hole to ensure the limiting effect. Multiple first threaded holes are evenly formed on the limit ring, and multiple second threaded holes are evenly formed at the lower end of the sleeve. The first threaded holes and second threaded holes are positioned correspondingly and have the same diameter. Bolts are installed through the first threaded holes and second threaded holes to ensure a reliable connection between the limit ring and the sleeve. The shaft passes through the center hole of the limit ring.

[0006] Multiple layers of pads are horizontally arranged in the middle of the column to support the heating coils. Multiple tie rods are horizontally and evenly fixed between the outer wall of the pads and the inner wall of the column to ensure the stability and reliability of the pad positions. The shaft passes through the central hole of the pads. A heating coil is arranged on the pads near the shaft. One end of the multiple heating coils is connected to an electric wire, which supplies power to the multiple heating coils. The heating coils heat up, which heats the shaft, increasing the temperature of the shaft and the sleeve, thereby preventing freezing at the connection between the shaft and the first Teflon bearing, and between the sleeve and the second Teflon bearing.

[0007] Preferably, multiple baffles are vertically and evenly fixed at the upper end of the pad located on the outer edge of the heating coil, and a baffle is horizontally fixed at the upper end of the baffle and above the heating coil to limit the position of the heating coil and prevent the heating coil from detaching from the pad.

[0008] Preferably, an O-ring is provided in the groove at the upper end of the second Teflon bearing to seal the connection between the sleeve and the cylinder, preventing moisture or dust from entering the second Teflon bearing.

[0009] Preferably, a pressure ring is horizontally fixed at the lower end of the end cap and located on the outer edge of the sleeve. The pressure ring corresponds to the position of the O-ring seal. The outer diameter of the pressure ring is smaller than the inner diameter of the groove to ensure tight contact between the O-ring seal and the outer wall of the sleeve.

[0010] Preferably, a convex ring is fixedly provided at the upper end of the column and at the outer edge of the groove. The upper end face of the convex ring is arc-shaped, and the height of the convex ring is less than the height of the pressure ring. The convex ring supports the end cap and reduces the contact area, thus ensuring a reliable connection between the end cap and the column.

[0011] The beneficial effects of this utility model are as follows: multiple layers of pads are provided inside the column, and heating coils are provided on the pads near the shaft. One end of each heating coil is connected to an electric wire, which supplies power to the heating coils. The heating coils heat up and heat the shaft, thereby increasing the temperature of the shaft and the sleeve. This prevents freezing at the connection between the shaft and the first Teflon bearing, and between the sleeve and the second Teflon bearing, ensuring the normal rotation of the anemometer and the accuracy of the measurement results.
