[0002] In modern industrial production, transportation, scientific research and many other fields, accurate measurement of object speed is crucial. Traditional speed detection methods, such as mechanical contact measurement, are not only cumbersome to operate, but also susceptible to wear and vibration in high-speed, high-precision measurement scenarios, resulting in large measurement errors and short equipment lifespan. With the development of technology, the demand for non-contact speed detection technology has surged. Infrared photoelectric technology, with its advantages of high precision, high reliability, fast response speed and non-contact measurement, has become a popular choice in the field of speed detection. It can effectively avoid the drawbacks of traditional methods and is especially suitable for complex environments with high temperature, high pressure, high speed and strict accuracy requirements.
[0003] However, current infrared photoelectric speed detection sensors are usually installed using fixing screws and bolts, which makes it extremely inconvenient to adjust the infrared photoelectric speed detection sensor body. In addition, the heat dissipation effect of traditional speed detection sensors is not good, resulting in low working efficiency and detection accuracy. To address this, we propose an infrared photoelectric speed detection sensor device. Utility Model Content
