Description

Technical Field

[0001] The utility model relates to the technical field of wind speed sensors, in particular to a wind speed sensor. Background Art

[0002] Wind speed sensors are critical equipment widely used in fields such as meteorological observation, environmental monitoring, aerospace, and industrial production. Traditional wind speed sensors consist of a main housing fixed to a bracket and a cup assembly mounted on the main housing. The cup assembly typically consists of several spaced-apart cups. These cups rotate in response to wind, and the wind speed can be inferred by measuring their rotational speed.

[0003] However, in cold weather, especially during winter or at high latitudes, the cup assembly can be susceptible to frost accumulation. Frost formation can significantly affect the cup's proper rotation, leading to measurement deviations and even sensor failure. Therefore, antifreeze protection is particularly important for wind speed sensors.

[0004] While some wind speed sensors currently on the market use heating to prevent ice from forming on the cup assembly, these designs often focus solely on heating the interior of the main housing, neglecting the need to heat the cup itself. This heating approach is limited in effectiveness, especially on exposed components like the cup, which have a large surface area, where frost can easily accumulate. This is especially true for bowl-shaped cups, where snow and ice easily accumulate and cannot be effectively heated and melted.

[0005] In view of the above situation, the present application proposes a wind speed sensor with good heating and antifreeze effect. Utility Model Content

[0006] In view of the deficiencies in the background technology, the utility model provides a wind speed sensor.

[0007] The technical solution adopted by the present invention is: a wind speed sensor, including a bracket and a wind cup assembly arranged on the bracket, the wind cup assembly including a main shell and wind cups arranged at intervals on the main shell, and also including a heating assembly, the heating assembly including an internal heating part arranged in the main shell and adapted to the shape of the main shell, a wind cup heating part arranged in the wind cup, and an external heating part extending to the outside of the wind cup, the internal heating part, the wind cup heating part and the external heating part being an integrally formed structure.

[0008] Furthermore, the main shell includes a lower shell and an upper shell covering the lower shell, the lower shell has a housing cavity for accommodating the internal heating part, the housing cavity is provided with a positioning boss, and the internal heating part is provided with a positioning through hole through which the positioning boss passes.

[0009] Furthermore, the wind cup is a bowl-shaped structure, which consists of an inner bowl sleeve and an outer bowl sleeve. The outer bowl sleeve is integrally formed with the upper shell, and a connecting screw is provided at the bottom of the outer bowl sleeve. The connecting screw passes through the connecting hole of the inner bowl sleeve and is fixed by a nut.

[0010] Furthermore, an installation gap is left between the inner bowl sleeve and the outer bowl sleeve, and the wind cup heating part is sleeved in the above installation gap.

[0011] Furthermore, the wind cup heating part is a circular ring structure, which is sleeved on the inner bowl sleeve.

[0012] Furthermore, the top of the upper shell is provided with a tower-shaped platform, and a temperature sensor is fixed on the top of the platform.

[0013] The beneficial effects of the utility model are:

[0014] 1. Comprehensive and sufficient heating: The heating component of the present application includes not only an internal heating part, but also a specially set wind cup heating part and an external heating part. The three are formed in one piece, which ensures the uniformity and efficiency of the heating process and avoids the accumulation of frost on the inner and outer surfaces of the wind cup.

[0015] 2. Improve measurement accuracy: Since the heating component can effectively prevent the wind cup assembly from icing, it ensures the free rotation of the wind cup under any climatic conditions, thereby improving the accuracy and reliability of wind speed measurement.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] The utility model provides a wind speed sensor.

[0025] In this embodiment, referring to Figure 1-3 The wind speed sensor includes a bracket 1 and a wind cup assembly set on the bracket 1. The wind cup assembly includes a main shell 3 and wind cups 4 spaced apart from each other on the main shell. It also includes a heating assembly 5. The heating assembly 5 includes an internal heating part 6 set in the main shell and adapted to the shape of the main shell, a wind cup heating part 7 set in the wind cup, and an external heating part 8 extending to the outside of the wind cup. The internal heating part, the wind cup heating part and the external heating part are an integrally formed structure.

[0026] In the above technical solution, this application achieves comprehensive heating of the wind speed sensor from the inside out by providing an internal heating portion, a wind cup heating portion, and an external heating portion, effectively preventing the accumulation of frost on various parts of the sensor and ensuring the normal operation of the sensor in low-temperature environments. In particular, the provision of a wind cup heating portion within the wind cup to independently heat the wind cup can prevent the accumulation of wind and snow on the wind cup.

[0027] Specifically, the main shell includes a lower shell 9 and an upper shell 10 covering the lower shell 9, the lower shell has a housing cavity 11 for accommodating the internal heating part, the housing cavity 11 is provided with a positioning boss 13, and the internal heating part is provided with a positioning through hole 14 through which the positioning boss passes.

[0028] In this technical solution, positioning bosses in the lower housing mate with positioning holes in the inner heating element, ensuring precise positioning of the inner heating element during installation and avoiding uneven heating due to positional offset. The combination of positioning bosses and positioning holes improves the installation stability of the heating element, reduces the risk of displacement due to vibration or external impact, and thus enhances the reliability of the heating element.

[0029] Specifically, the wind cup is a bowl-shaped structure, which consists of an inner bowl sleeve 15 and an outer bowl sleeve 16. The outer bowl sleeve is integrally formed with the upper shell, and a connecting screw 17 is provided at the bottom of the outer bowl sleeve. The connecting screw passes through the connecting hole of the inner bowl sleeve and is fixed by a nut 18.

[0030] In this technical solution, the integrated design of the outer bowl and upper shell increases the overall rigidity of the wind cup assembly, improving its resistance to wind pressure and making it suitable for use in strong wind environments. The inner bowl is then attached to the outer bowl and secured with a connecting screw and nut, simplifying the assembly and disassembly of the wind cup and facilitating routine maintenance and inspection.

[0031] Specifically, an installation gap is left between the inner bowl sleeve and the outer bowl sleeve, and the wind cup heating part is sleeved in the above installation gap.

[0032] In the above technical solution, the installation gap between the inner bowl sleeve and the outer bowl sleeve provides a good installation space for the wind cup heating part, which is conducive to the uniform distribution of heat, ensures the synchronous heating of the inner and outer walls of the wind cup, and prevents the occurrence of local overheating or non-heating.

[0033] Specifically, the wind cup heating part is a circular ring structure, which is sleeved on the inner bowl sleeve.

[0034] In the above technical solution, the wind cup heating part adopts a circular ring structure design, which can be well fitted on the wind cup and can transfer heat to the wind cup more evenly.

[0035] Specifically, the top of the upper shell is provided with a tower-shaped platform 19 , and a temperature sensor 20 is fixed on the top of the platform.

[0036] In the above technical solution, by setting a tower-shaped structure platform on the top of the upper shell, it is possible to effectively prevent wind and snow from accumulating on the top of the shell. The temperature sensor is used to detect stability and feed back to the controller of the heating component, so that the heating component can be turned off or on automatically according to the stability of the environment.

[0037] Technical personnel please note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
