Description

Technical Field

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

[0002] With the continuous improvement of the level of industrial automation, the accurate measurement of environmental parameters has become increasingly important. Among them, wind speed, as one of the important parameters in the fields of meteorology, industrial production, aerospace, etc., its accurate measurement is of great significance for ensuring the normal operation of related industries. Although traditional wind speed sensors can meet the basic measurement requirements, they often seem powerless when facing harsh environments, such as problems like rain intrusion and dust accumulation.

[0003] At present, the main structure of common wind speed sensors on the market includes a wind cup assembly, a coil bracket, a coil, a main body bracket, and a housing sleeved outside the main body bracket. There is often a gap between the wind cup lower cover of the wind cup assembly and the outer wall of the housing. For example, the wind speed sensor disclosed in the application number 2022228278003. When the wind speed sensor with such a structure is used in a harsh environment, dust and rain are easy to enter the interior from the gap, affecting the service life and performance of the coil.

[0004] Therefore, this application proposes an electrothermal wind speed sensor, aiming to improve the waterproof and dustproof performance of the sensor, thereby enhancing its reliability and service life in various complex environments. Content of the Utility Model

The wind cup assembly includes a wind cup upper cover, a wind cup lower cover, and a wind cup. The wind cup lower cover extends downward with a connecting sleeve. An upper retaining ring is provided on the inner wall of the connecting sleeve. There is a first gap between the upper retaining ring and the outer wall of the housing. A lower retaining ring is provided on the housing below the upper retaining ring. There is a second gap between the lower retaining ring and the inner wall of the connecting sleeve. The outer wall of the housing bulges outward to form an annular step. The annular step forms a surrounding step upward. The surrounding step surrounds the outer wall of the connecting sleeve. An outer retaining ring is provided on the outer wall of the connecting sleeve above the surrounding step. There is a third gap between the outer retaining ring and the surrounding step.

[0007] Further, the surrounding step and the connecting sleeve are in clearance fit.

[0008] Further, the bottom of the housing is provided with ventilation holes.

[0009] Furthermore, the wind cup includes an inner wind cup and an outer wind cup, and the inner wind cup and the outer wind cup are detachably connected by bolts.

[0010] Furthermore, an electric heating film is provided between the upper cover of the wind cup and the lower cover of the wind cup.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0024] The present utility model provides an electric heating wind speed sensor.

[0025] In this embodiment, referring to Figures 1-4 , the electric heating wind speed sensor includes a wind cup assembly 1, a coil bracket 2, a coil, a main body bracket 3, and an outer shell 4 sleeved outside the main body bracket. The wind cup assembly includes an upper cover 5 of the wind cup, a lower cover 6 of the wind cup, and a wind cup 7. The lower cover 7 of the wind cup extends downward with a connecting sleeve 8. An upper retaining ring 9 is provided on the inner wall of the connecting sleeve 8. A first gap 10 is left between the upper retaining ring 9 and the outer wall of the outer shell. A lower retaining ring 11 is provided on the outer shell below the upper retaining ring. A second gap 12 is left between the lower retaining ring 11 and the inner wall of the connecting sleeve. The outer wall of the outer shell bulges outward to form an annular step 13. The annular step 13 forms an enclosing step 14 upward. The enclosing step 14 encloses the outer wall of the connecting sleeve. An outer retaining ring 15 is provided on the outer wall of the connecting sleeve above the enclosing step. A third gap 16 is left between the outer retaining ring 15 and the enclosing step.

[0026] In the above technical solution, by providing an upper retaining ring in the connecting sleeve extending downward below the lower cover of the wind cup and providing a lower retaining ring at the corresponding position of the outer shell, it can effectively prevent external dust and rain from infiltrating into the sensor interior through the gap between the connecting sleeve and the outer shell, improving the protection level of the sensor.

[0027] The design of the annular step and the surrounding step extends the length of the gap between the housing and the connecting sleeve, which can further improve the waterproof and dustproof effects. At the same time, although the upper and lower retaining rings, the outer retaining ring and the surrounding step are designed, there are still ventilation gaps left to ensure the ventilation and heat dissipation performance of the coil.

[0028] Specifically, there is a clearance fit between the surrounding step and the connecting sleeve; and the bottom of the housing is provided with a ventilation hole 17.

[0029] In this embodiment, the ventilation hole is arranged at the bottom of the housing, forming a ventilation channel with the gap above the housing, which helps to dissipate the heat inside the sensor, can reduce the accumulation of internal condensed water, and further improve the durability and reliability of the sensor.

[0030] Specifically, the wind cup includes an inner wind cup 18 and an outer wind cup 19, and the inner wind cup and the outer wind cup are detachably connected by bolts.

[0031] In this embodiment, by detachably connecting the inner wind cup and the outer wind cup with bolts, the wind cup assembly can be quickly disassembled and replaced when damaged or in need of cleaning, simplifying the maintenance process and improving the work efficiency. The detachable design enables the sensor to adjust the wind cup configuration according to different environmental conditions, increasing the flexibility and adaptability of the sensor.

[0032] Specifically, an electric heating film 20 is arranged between the upper cover and the lower cover of the wind cup. The electric heating film includes an inner electric heating film 21 arranged between the upper cover and the lower cover of the wind cup to heat the upper cover and the lower cover of the wind cup, and an outer electric heating film 22 arranged between the inner wind cup and the outer wind cup to heat the wind cup.

[0033] In this embodiment, the design of the inner and outer electric heating films can not only better control the temperature of the wind cup assembly, but also achieve a better anti-freezing effect.

[0034] Specifically, a drain port 23 is arranged on the inner side of the surrounding step.

[0035] In this embodiment, the drain port design can drain the rainwater and dust on the inner side of the surrounding step, preventing the rainwater from accumulating on the inner side of the surrounding step.

[0036] All technicians should note that although the present utility model has been described according to the above specific embodiments, the idea of the present utility model is not limited to this utility model only. Any modification using the idea of the present utility model will be included in the scope of protection of this patent right.
