Description

Technical Field

[0001] This invention relates to the field of wind measurement technology, and in particular to a wind cup assembly, an anemometer, and a method for preventing the anemometer from freezing. Background Technology

[0002] In the existing technology, anemometers, as wind speed measuring devices, use a wind cup to drive a rotating shaft to rotate, and generate an electrical signal through the rotation of the shaft to complete the measurement of wind speed.

[0003] When the temperature is low, the anemometer's cups are constantly exposed and prone to icing. The increased weight of the iced cups slows down their rotation, significantly reducing the accuracy of wind speed detection and affecting the accuracy of the anemometer sensor. Furthermore, the uneven mass of the cups due to localized icing causes dynamic balance issues, indirectly shortening the product's lifespan.

[0004] Current technology primarily avoids icing by uniformly heating all parts of the anemometer, which wastes a significant amount of heat, especially in extremely cold environments where electricity is extremely valuable. In fact, the wind-receiving rotating part of the anemometer is the component most in need of heating; freezing of this part will have a significant impact.

[0005] Based on the above problems, this invention proposes a wind cup assembly, an anemometer, and an anti-freezing method for the anemometer, which can stably and effectively cope with low temperature weather, especially an anemometer that can operate normally in low temperature, snow, freezing rain and other weather environments.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] Unless otherwise stated, all technical and scientific terms used in the embodiments of this invention have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0038] It should be noted that the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0039] Please see Figures 1 to 7 The first aspect of the present invention provides a wind cup assembly 10, which has a first cup body 101 and a second cup body 102 that are nested and overlapped with each other. The wind cup assembly 10 has a hemispherical outer contour structure and can be constructed on the outer edge of the wind speed bracket by welding. This can achieve effective fixation between the wind cup assembly and the wind speed bracket.

[0040] Please see Figures 1 to 5In one feasible embodiment, the second cup body 102 has an outer cup body 1021 with a hemispherical outer contour structure, an outer cup body flange 1022 with a cup rim circumference of the outer cup body 1021, and an annular groove (not shown in the figure) formed around the inner wall of the cup body; the first cup body 101 has an inner cup body 1011 with a hemispherical outer contour structure that overlaps and is nested inside the outer cup body 1021, an inner cup body flange 1012 with a cup rim circumference of the inner cup body 1011, and an annular rolled edge 1013 disposed opposite to the inner cup body flange 1012. After the first cup body 101 and the second cup body 102 of any wind cup assembly 10 are assembled together by the edge rolling process, a gap space 103 for accommodating the flexible heating band is formed between the first cup body 101 and the second cup body 102. The gap space 103 is formed by the annular groove on the second cup body 102 and a part of the cup body of the first cup body 101 corresponding to the annular groove.

[0041] Please see Figure 1 , Figure 6 and Figure 7 In another feasible embodiment, the second cup body 102 has an outer cup body 1021 with a hemispherical outer contour structure and an outer cup body flange 1022 formed around the outer periphery of the rim of the outer cup body 1021; the first cup body 101 has an inner cup body 1011 with a hemispherical outer contour structure that overlaps and is nested within the outer cup body 1021, an inner cup body flange 1012 formed around the outer periphery of the rim of the inner cup body 1011, and an annular rolled edge 1013 oppositely disposed to the inner cup body flange 1012. Further, the inner cup body 1011 further includes a first inner cup body portion 10111, a second inner cup body portion 10112, and a connecting portion 10113 formed between the first inner cup body portion and the second inner cup body portion. The first inner cup body portion 10111 is formed on the closed end side of the inner cup body, and the second inner cup body portion 10112 is formed on the open end side of the inner cup body.

[0042] Please see Figures 2 to 7 After the first cup body 101 and the second cup body 102 of any wind cup assembly 10 are assembled together by the edge rolling process, a gap space 103 for accommodating the flexible heating band is formed between the first cup body 101 and the second cup body 102. The gap space 103 is formed by the inner cup body first part 10111, the connecting part 10112 and a part of the cup body of the second cup body 102 corresponding to the inner cup body first part 10111.

[0043] Before the first cup body 101 and the second cup body 102 of the wind cup assembly 10 are assembled together by rolling the edges, sealant can be applied to corresponding positions of the outer cup body flange 1022, the inner cup body flange 1012 and / or the rolled edge 1013 (not shown in the figure). Alternatively, a sealing structure can be constructed between the overlapping positions of the outer cup body flange 1022 and the inner cup body flange 1012 (not shown in the figure). The above methods can effectively solve the sealing and waterproofing problem of the wind cup assembly. For example, an annular groove and a sealing ring adapted to the annular groove can be constructed on the outer cup body flange 1022.

[0044] In one feasible embodiment, the wind cup assembly 10 further comprises a first heating element 104 sandwiched between a first cup body 101 and a second cup body 102 that overlap and nest with each other. Only a portion of the first heating element 104 is sandwiched between the first cup body 101 and the second cup body 102. Specifically, a portion of the first heating element 104 sandwiched between the first cup body 101 and the second cup body 102 forms a gap space 103 for accommodating a flexible heating band. Correspondingly, the second cup body 102, serving as the outer cup body, is provided with an opening (not shown) communicating with the gap space 103, which allows a portion of the first heating element 104 employing a flexible heating band to be accommodated within the gap space 103 through this opening (not shown).

[0045] Please see Figures 8 to 10 The second aspect of the present invention provides a wind measuring instrument 100, including a rotating shaft 2; a wind detection element 1, which is fixed to one end of the rotating shaft 2; a coil lower housing 4, in which a bearing 45 is disposed, and the rotating shaft 2 is disposed on the bearing 45. The wind detection element 1 further includes a wind cup holder 11 and a wind cup assembly 10 fixed on the wind cup holder 11, which together form a wind turbine-shaped wind detection structure; the wind detection element 1 is rotatably mounted on the lower housing 4 of the coil via a rotating shaft 2 through a bearing 45.

[0046] The wind cup assembly 10 has a first cup body 101 and a second cup body 102 that are nested and overlapped with each other, and / or a first heating element 104 sandwiched between the first cup body 101 and the second cup body 102. In one feasible embodiment, there are three wind cup assemblies 103, which are located on the same circumference and are evenly distributed to enable wind speed measurement. The first heating element 104 is placed between the first cup body 101 and the second cup body 102 in the form of a flexible heating strip.

[0047] The wind cup support 11 is further constructed from an upper support 111 and a lower support 112. The lower support 112 is fastened to the upper support 111 with screws, and one end of the rotating shaft 2 is fixed to the wind speed support 11 through an end fixing mechanism (not shown in the figure). Specifically, the second cup body of the wind cup assembly is welded to the upper support 111 of the wind cup, and the lower support 112 is locked to the upper support with screws. This detachable design facilitates subsequent maintenance of devices such as the first heating element 104.

[0048] The anemometer 100 further includes a coil upper shell 5, one end of which is fixed to the wind cup support 11, and the other end is fixed to the secondary coil 46 fixed on the coil lower shell 4. The coil upper shell 5 further includes a ring-shaped fixing wall 51, a waterproof eaves 52 arranged in a ring around the outer periphery of the fixing wall 51, and a connecting wall 53 arranged in a ring around the inner periphery of the fixing wall 51 and parallel to the waterproof eaves 52. A gap space is formed between the waterproof eaves 52 and the connecting wall 53.

[0049] The lower coil housing 4 further includes a coil base 41; two bearing chambers (not shown in the figure) constructed on the coil base 41, one bearing chamber constructed at one end of the coil base 41 and the other bearing chamber constructed at the other end of the coil base 41; and an upper part 43 of the inner housing constructed at the other end of the coil base 41 and communicating with the bearing chamber. A second heating element 105 electrically connected to the wireless heating transmitter board is further attached to the inner wall of the upper part 43 of the inner housing near the bearing chamber. The second heating element 105 is attached to the inner wall of the upper part 43 of the inner housing in the form of a flexible heating strip. The above structure can effectively prevent icing between the outer shell 7 and the inner housing of the anemometer, ensuring that the bearing in the bearing chamber does not experience abnormal operation due to freezing, thereby preventing deviation in the anemometer measurement. A primary coil 47 is also further constructed on the coil base 41, placed along the rotation axis 2 and stacked below the secondary coil 46.

[0050] The anemometer further includes a bottom shell 6, which together with the lower coil shell 4 forms an inner shell. The bottom shell 6 further includes a bottom shell base 61 with openings at both ends and a hollow interior, a lower part of the inner shell 62 that is cylindrical at one end of the bottom shell base 61 and fixed to the upper part of the inner shell 43, and an anemometer fixing connector 63 at the other end of the bottom shell base.

[0051] The upper half 43 and the lower half 62 of the inner shell are fixed to each other by threaded fastening. An annular second waterproof groove (not shown in the figure) and an O-ring 64 fitted inside the second waterproof groove (not shown in the figure) are constructed between the parts where the upper half 43 and the lower half 62 of the inner shell are fixed to each other.

[0052] The lower edge of the bottom shell base 61 is further constructed with an annular boss 611. The lower half of the inner shell 62 is fixed to the bottom shell base 61 by welding, and the lower edge of the inner shell 62 abuts against the boss 611.

[0053] The anemometer mounting connector 63 is fixed to the base 61 by the cooperation of screws (not shown in the figure), threaded holes (not shown in the figure) on the base 61, and through holes (not shown in the figure) on the anemometer mounting connector. After the base 6 and the lower coil housing 4 are assembled, they together form a cavity for accommodating the integrated circuit device of the anemometer. In order to ensure that the cavity has excellent airtightness and waterproofness, a third waterproof groove (not shown in the figure) and an O-ring 65 fitted inside the third waterproof groove (not shown in the figure) are constructed at the gap between the base 6 and the anemometer mounting connector.

[0054] The anemometer 100 further includes a cylindrical outer shell 7, which is fitted around the bottom shell 6 and the lower coil shell 4, and forms a gap between the outer shell 7 and the bottom shell 6 and the lower coil shell 4. The upper edge of the outer shell 7 extends into the gap space formed between the waterproof eaves 52 and the connecting wall 53.

[0055] The anemometer 100 of the present invention has made reasonable and effective improvements, particularly in the rotating shaft 2 and its fixing method, the separate structure design of the bottom shell 6 and the bottom shell base 61, and the design of multiple waterproof structures. These improvements not only take into account the product performance, but also allow the main components to be manufactured by machining, thereby reducing the amount of material used and the manufacturing cost of the product.

[0056] In one feasible embodiment, the outer shell 7 of the anemometer is fixed to the inner shell by an outer shell fixing structure constructed between the outer shell 7 and the inner shell. The outer shell fixing structure consists of a plurality of fixing strips 612 constructed on the outer surface of the outer perimeter of the inner shell and evenly distributed, and fixing components that fix the outer shell 7 to the fixing strips.

[0057] In a preferred embodiment, the aforementioned fixing strips 612 are constructed along the axial direction of the inner shell on the outer periphery of the inner shell. The fixing components are threaded holes (not shown in the figure) constructed on the fixing strips, through holes (not shown in the figure) constructed on the outer shell, and screws (not shown in the figure) that are adapted to the threaded holes (not shown in the figure) and through holes (not shown in the figure).

[0058] In one feasible embodiment, the outer shell and the fixing strip 612 can be an integral structure, which is formed by mechanical cutting of a cylindrical tube; in another feasible embodiment, the outer shell and the fixing strip 711 can be assembled and welded together, and the outer shell 7 has a fixing groove (not shown in the figure) adapted to the fixing strip 612. After the fixing strip 612 is installed in the fixing groove, the fixing strip 612 is fixed to the outer shell by welding.

[0059] Please see Figure 9 and Figure 11 The anemometer of the present invention further includes a first power supply circuit 81, a first temperature acquisition unit 82, and a first temperature control unit 83 corresponding to the first heating element 104. The first temperature acquisition unit 82 is constructed between the upper support 111 and the lower support 112 and is electrically connected to the first temperature control unit 83 constructed on the wireless heating receiver board. The first heating element 104 is electrically connected to the first temperature control unit 83 through the first power supply circuit 81 constructed on the wireless heating receiver board. A second power supply circuit 84, a second temperature acquisition unit 85, and a second temperature control unit 86 are provided corresponding to the second heating element 105. The second temperature control unit 86 is electrically connected to the second temperature acquisition unit 85. The second temperature acquisition unit 85 and the second heating element 105 are both constructed in a cavity accommodating the anemometer's integrated circuit device, and the second heating element 105 is also constructed within the cavity accommodating the anemometer's integrated circuit device. Element 105 is constructed on the inner wall of the inner shell near the bearing chamber. The second heating element 105 is electrically connected to the second temperature control unit 85 constructed on the wireless heating transmitter plate via the second power supply circuit 84 constructed on the wireless heating transmitter plate. The second temperature control unit 86 is electrically connected to the primary coil 47 via the third power supply circuit 87 constructed on the wireless heating transmitter plate. The first temperature acquisition unit 82 is used to acquire the real-time temperature of the wind cup holder 11. The second temperature acquisition unit 85 is used to acquire the real-time temperature of the accommodating cavity. The first temperature control unit 83 is used to selectively connect or disconnect the first power supply circuit according to the acquired real-time temperature of the wind cup holder 11. The second temperature control unit 86 is used to selectively connect or disconnect the second power supply circuit 84 and the third power supply circuit 87 according to the acquired real-time temperature of the accommodating cavity.

[0060] In specific embodiments, the first power supply circuit 81, the second power supply circuit 84, and the third power supply circuit 87 can be configured in a targeted manner according to actual needs. For example, the second power supply circuit 84 and the third power supply circuit can be configured as switching circuits that can be controlled to be turned on and off by the second temperature control unit 86, and the first power supply circuit 81 can be configured as a switching circuit that can be controlled to be turned on and off by the first temperature control unit 83.

[0061] It should be noted that the wireless heating transmitter board (not shown in the figure), control board (not shown in the figure), EMC protection board (not shown in the figure), etc. are constructed in the housing cavity that houses the integrated circuit device of the anemometer, and are placed at intervals from top to bottom along the rotation axis 2.

[0062] A third aspect of the present invention provides a method for preventing freezing of an anemometers. This method is applicable to the anemometers provided in the second aspect of the present invention. Specifically, the method includes: under normal operating conditions of the anemometer, Step S1: In response to the real-time temperature of the accommodating cavity obtained by the second temperature acquisition unit 83 being lower than the first preset temperature, the second temperature control unit 84 connects the third power supply circuit 87 between the wireless heating transmitter and the primary coil 47. After the power is coupled through the primary coil 47 and the secondary coil 46 and conditioned by the wireless heating receiver, the wireless heating receiver controls the wireless heating receiver to connect the first power supply circuit 81 of the first heating element 104, and the second temperature control unit 86 connects the second power supply circuit 84 between the wireless heating transmitter and the second heating element 105. Step S2: In response to the real-time temperature of the accommodating cavity obtained by the second temperature acquisition unit 83 being higher than the second preset temperature, the second temperature control unit 84 disconnects the second power supply circuit 84 between the wireless heating transmitter and the second heating element 105, and disconnects the third power supply circuit 87 between the wireless heating transmitter and the primary coil 47. Alternatively, in response to the real-time temperature of the accommodating cavity obtained by the second temperature acquisition unit 83 not being higher than the second preset temperature and the real-time temperature of the wind cup holder obtained by the first temperature acquisition unit 81 being higher than the third preset temperature, at least the first temperature control unit 82 disconnects the first power supply circuit 81 of the first heating element 104. At the same time, the second temperature control unit 84 may optionally disconnect the third power supply circuit 87 between the wireless heating transmitter and the primary coil 47, wherein the preset value of the first preset temperature is less than the preset value of the second preset temperature, and the preset value of the second preset temperature is less than the preset value of the third preset temperature. For example, the preset value of the first preset temperature is 0℃, the preset value of the second preset temperature is 40℃, and the preset value of the third preset temperature is 70℃. The above examples are only examples of a feasible embodiment and do not constitute a limitation on the anti-icing method for anemometers disclosed in this patent. All equivalent or alternative solutions that are the same as or similar to the anti-icing method for anemometers of this invention are included within the scope of the claims of this patent.

[0063] The aforementioned anti-icing method for anemometers effectively solves the problem of poor ice-melting when ice accumulates from the bottom up, ensuring the normal operation of the anemometer's wind detection elements.
