Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind speed sensor technology, and in particular to an antifreeze wind speed sensor. Background Technology
[0002] The wind speed sensor primarily uses high-quality aluminum alloy profiles with an electroplated and powder-coated surface, providing excellent corrosion resistance. This effectively ensures the instrument remains rust-free during long-term use. Combined with a smooth internal bearing system, it ensures the accuracy of the collected information. It is a user-friendly, high-performance, and highly reliable intelligent instrument. It can be widely used for measuring wind speed in greenhouses, environmental protection facilities, weather stations, construction sites, docks, and aquaculture. In low-temperature winter environments, cup-type wind speed sensors are susceptible to freezing, which can directly lead to the failure of their core function of accurate measurement. Therefore, antifreeze measures must be implemented during winter to prevent freezing.
[0003] A current Chinese patent publication number CN210665789U describes an antifreeze anemometer. According to its specification, the main antifreeze measure of this device is to heat and insulate the internal electrical components by installing a heating element inside the housing of the cup-type anemometer. However, if the heating element is damaged and needs repair, the entire device must be disassembled for repair, which is relatively cumbersome. In addition, after internal heating, the heat will still come into direct contact with the cold air outside through the housing, thereby reducing the insulation effect of the device.
[0004] Therefore, it is necessary to provide a new antifreeze wind speed sensor to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an antifreeze wind speed sensor.
[0006] The antifreeze wind speed sensor provided by this utility model includes: a wind speed sensor body, and an insulation component for heat preservation and antifreeze is installed on the outside of the wind speed sensor body;
[0007] The insulation component includes two insulation half-shells, which are symmetrically distributed outside the housing of the wind speed sensor body. A heating tube is fixedly installed on the inner top of one insulation half-shell, and a fan for conveying air is fixedly installed on the inner wall of both insulation half-shells.
[0008] Connecting ears are fixedly installed on the side wall of the insulated half shell, and the connecting ears on opposite sides are fixed together by bolts.
[0009] Preferably, a plurality of evenly distributed heat-conducting fins are fixedly installed on the outer wall of the wind speed sensor body shell, and the heat-conducting fins are located below the output end of the fan.
[0010] Preferably, heat-conducting half-cylinders are fixedly installed on the inner walls of both insulated half-shells, and the heat-conducting half-cylinders on both sides are symmetrically distributed on the outside of the wind speed sensor body, and the inner walls of the heat-conducting half-cylinders do not contact the side walls of the heat-conducting fins.
[0011] Preferably, the outer wall of the heat-conducting half-cylinder does not contact the inner wall of the heat-insulating half-shell, and a return air pipe is fixedly installed on the top of the heat-conducting half-cylinder, with the bottom end of the return air pipe penetrating through the top of the heat-conducting half-cylinder.
[0012] Preferably, the bottom of the wind speed sensor is fixedly mounted on a mounting base, and the top of the mounting base has a through hole, which is located inside the insulation half-shell.
[0013] Preferably, symmetrically distributed support plates are fixedly installed on both sides of the top of the mounting chassis, and insert rods are fixedly installed on the opposite surfaces of the support plates on both sides.
[0014] Preferably, a mating piece is inserted into the outside of the insertion rod, and the side wall of the mating piece is fixedly connected to the inner wall of the insulation half shell.
[0015] Compared with related technologies, the antifreeze wind speed sensor provided by this utility model has the following advantages:
[0016] 1. This utility model achieves more comprehensive insulation of the wind speed sensor body by covering it with a protective insulation component and providing auxiliary heating inside. At the same time, the interlocking insulation half-shell eliminates the need to disassemble the wind speed sensor as a whole, thus facilitating the disassembly and maintenance of the insulation component later.
[0017] 2. This utility model places the heating tube inside the top of the insulation half shell. When the heating tube is working, the heat generated by the heating tube can assist in heating the top of the insulation half shell. At this time, the heat generated at the top will assist in heating the wind cup in the wind speed sensor body above, thereby reducing the impact of water stains remaining on the wind cup freezing on the wind speed sensor measurement during rainy or snowy weather.
[0018] 3. When the heating element is heating, the working fan blows the hot air generated by the heating element downwards and returns it upwards through the return air pipe. This allows the hot air to circulate within the insulation half-shell, thus fully filling the internal space of the insulation half-shell and improving the heating and insulation effect of the internal space.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0027] Please see Figures 1 to 5 The present invention provides a frost-resistant wind speed sensor, which includes: a wind speed sensor body 1, and a heat-insulating component 3 installed on the outside of the wind speed sensor body 1 for heat preservation and frost protection.
[0028] In the embodiments of this utility model, please refer to Figures 1 to 5 The insulation component 3 includes an insulation half-shell 31. There are two insulation half-shells 31, which are symmetrically distributed outside the housing of the wind speed sensor body 1. A heating tube 32 is fixedly installed on the inner top of one insulation half-shell 31, and a fan 4 for conveying air is fixedly installed on the inner wall of both insulation half-shells 31. A connecting ear 312 is fixedly installed on the side wall of the insulation half-shell 31, and the connecting ears 312 on opposite sides are fixed together by bolts.
[0029] It should be noted that by covering the wind speed sensor body 1 with two symmetrically distributed heat-insulating half-shells 31, the two heat-insulating half-shells 31 can be joined together to form a complete heat-insulating shell, thereby forming a multi-sided heat-insulating structure on the outside of the wind speed sensor. Since the heat-insulating shell and the wind speed sensor body 1 do not contact each other, the space between the two can also form an isolation space, preventing the external temperature from directly acting on the wind speed sensor body 1. Therefore, the initial heat insulation and antifreeze of the wind speed sensor body 1 can be achieved.
[0030] Furthermore, the inner wall of the insulation half-shell 31 is also equipped with a temperature sensor (not shown in the figure) for monitoring the internal ambient temperature and a controller (not shown in the figure) for controlling the heating tube 32, the fan 4 and the temperature sensor. Thus, during use, the controller can monitor the ambient temperature outside the wind speed sensor in real time through the temperature sensor. When the detected temperature is lower than the set minimum temperature, the controller can control the heating tube 32 and the fan 4 to work, thereby providing auxiliary heating to the ambient temperature and helping to improve the antifreeze effect on the wind speed sensor. When the ambient temperature is higher than the set maximum temperature, the controller can stop the operation of the heating tube 32 and the fan 4, thereby avoiding the useless work generated by the continuous operation of the heating tube 32 and the fan 4.
[0031] Meanwhile, since the heating element 32 is located at the inner top of the insulation half-shell 31, when the heating element 32 is working, the heat generated by the heating element 32 can assist in heating the top of the insulation half-shell 31. At this time, the heat generated at the top will assist in heating the wind cup in the wind speed sensor body 1 above, thereby reducing the impact of water stains remaining on the wind cup freezing on the wind speed sensor measurement during rainy or snowy weather.
[0032] In this embodiment: Since the two insulation half shells 31 in the insulation component 3 are inserted and connected, when the insulation component 3 needs to be inspected and repaired later, the bolts that fix the two can be unscrewed to release the limit, and then the insulation half shells 31 on both sides can be pulled to complete the disassembly. There is no need to completely disassemble the wind speed sensor body 1, which can improve the flexibility of personnel to disassemble and repair the heating component later.
[0033] Furthermore, when insulation is not required in summer, the insulation component 3 can be disassembled and removed, thereby improving the flexibility of use of the insulation component 3.
[0034] In the embodiments of this utility model, please refer to Figures 1 to 5Multiple evenly distributed heat-conducting fins 11 are fixedly installed on the outer wall of the wind speed sensor body 1, and the heat-conducting fins 11 are located below the output end of the fan 4. Heat-conducting half-cylinders 5 are fixedly installed on the inner walls of the two insulation half-shells 31. The heat-conducting half-cylinders 5 are symmetrically distributed on the outside of the wind speed sensor body 1, and the inner wall of the heat-conducting half-cylinder 5 does not contact the side wall of the heat-conducting fins 11. The outer wall of the heat-conducting half-cylinder 5 does not contact the inner wall of the insulation half-shell 31. A return air pipe 51 is fixedly installed on the top of the heat-conducting half-cylinder 5, and the bottom end of the return air pipe 51 penetrates the top of the heat-conducting half-cylinder 5.
[0035] It should be noted that when the fan 4 blows the hot air generated by the heating tube 32 downwards, the heat-conducting fins 11 on the outside of the wind speed sensor body 1 can improve the heat conduction effect between the hot air and the wind speed sensor body 1, thus achieving the heating of its internal electrical components and reducing the impact of low temperature environment on the operation of electrical components.
[0036] In this embodiment, the heat-conducting half-cylinder 5 is installed between the heat-insulating half-cylinder and the wind speed sensor body 1. When the hot air flows downward to the bottom of the heat-conducting half-cylinder 5, as the hot air continues to flow downward, the hot air will turn around at the bottom of the heat-conducting half-cylinder 5 and flow upward along the outside of the heat-conducting half-cylinder 5. Then it can flow to the outside of the heating pipe 32 through the return air pipe 51. Therefore, the heating pipe 32 can circulate and heat the return air, so that the heated air can circulate, thereby improving the heating and heat preservation effect on the external space of the wind speed sensor body 1.
[0037] In the embodiments of this utility model, please refer to Figures 1 to 5 The bottom of the wind speed sensor is fixedly mounted with a mounting base 2, and the top of the mounting base 2 is provided with a through hole 21, which is located inside the heat-insulating half shell 31.
[0038] It should be noted that: by opening the through hole 21, during the installation of the device, the connecting wires of the electrical components in the device can be extended to the outside of the mounting base 2 through the through hole 21, so as to facilitate the connection of the electrical components with the external device. After the connecting wires pass through the through hole 21, they can be sealed with sealant inside the through hole 21, which can help improve the sealing effect of the insulation half shell 31.
[0039] In the embodiments of this utility model, please refer to Figures 1 to 5 The mounting base 2 has symmetrically distributed support plates 22 fixedly installed on both sides of the top, and the opposite surfaces of the support plates 22 are fixedly installed with insert rods 221. The insert rods 221 are inserted with connecting plates 311, and the side wall of the connecting plates 311 is fixedly connected to the inner wall of the insulation half shell 31.
[0040] It should be noted that by inserting the mating piece 311 on the outside of the insert rod 221, the insert rod 221 can position the insulation half shell 31 during installation, thus making the mating of the insulation half shell 31 inserted on both sides more precise, so as to facilitate the tightening and fixing of bolts.
[0041] Meanwhile, since the insertion rod 221 is set horizontally, after the insulation half shells 31 on both sides are fixed, the horizontally set insertion rod 221 can limit the insulation half shell 31 in the vertical direction by abutting against the docking piece 311. Therefore, it can prevent the insulation half shell 31 from being vertically loose outside the wind speed sensor, and thus achieve rapid and stable docking of the insulation half shell 31.
[0042] Furthermore, after docking, the top of the insulation half-shell 31 is located below the connecting cap between the wind cup shaft and the housing in the wind speed sensor body 1, which can avoid the influence on the rotation of the wind cup shaft after docking of the insulation half-shell 31.
[0043] Meanwhile, the mating surface of the insulated half-shell 31 is provided with a rubber pad, and the inner wall of the insulated half-shell 31 is provided with an insulation layer, which can improve the insulation effect of the insulated half-shell 31 after mating.
[0044] The working principle of the antifreeze wind speed sensor provided by this utility model is as follows:
[0045] When using the wind speed sensor, the device can be installed in the required position by mounting chassis 2 to measure the wind speed in the area to be monitored. During use, the controller inside the insulation half-shell 31 can monitor the temperature inside the insulation half-shell 31 in real time by monitoring the changes in the temperature sensor value.
[0046] When the temperature value is lower than the set temperature value, the heating tube 32 and the fan 4 will be controlled to work. The working heating tube 32 will keep the inner top of the insulation half shell 31 warm, while the working fan 4 will blow the hot air heated outside the heating tube 32 downward, so that the hot air flows downward in the heat-conducting half cylinder 5. During the flow of hot air, the heat-conducting fins 11 outside the wind speed sensor body 1 will increase the heat exchange between the wind speed sensor body 1 and the hot air, thus helping to improve the heating and insulation of the inside of the wind speed sensor body 1. When the controller detects through the temperature sensor that the ambient temperature outside the wind speed sensor body 1 is higher than the set value, it can stop the operation of the heating tube 32 to avoid the energy waste caused by useless work.
[0047] When the hot air flows to the heat-conducting half cylinder 5, it will flow upward in the opposite direction through the outside of the heat-conducting half cylinder 5 along with the downward blowing airflow, and then flow through the return air pipe 51 to the outside of the heating pipe 32 for later circulation.
[0048] While the heating tube 32 is heating, it can also heat the top of the insulation half shell 31. The heat generated above the top of the insulation half shell 31 will assist in heating the wind cup above the wind speed sensor body 1. Therefore, it can reduce the impact of water stains remaining on the wind cup freezing on the measurement effect of the wind speed sensor body 1 during rainy or snowy weather, and thus improve the antifreeze effect of the wind speed sensor body 1.
[0049] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0050] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
