Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a thread-screwing ultrasonic time-difference method sensor. Background Art

[0002] Ultrasound is a mechanical wave with an extremely short wavelength. Its wavelength in air is generally shorter than 2 cm (centimeter). It must rely on a medium to propagate and cannot exist in a vacuum (such as space). It propagates farther in water than in air, but because of its short wavelength, it is extremely easy to lose and scatter in air, and is not as far-reaching as audible sound and infrasound. However, its short wavelength makes it easier to obtain anisotropic sound energy, which can be used for cleaning, stone crushing, sterilization, etc. It has many applications in medicine and industry. A sensor (English name: transducer / sensor) is a detection device that can sense the information being measured and can convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. The existing patent is a channel ultrasonic time difference method sensor structure.

[0003] Patent publication number CN212254212U, which includes a pair of ultrasonic sensor groups and a mounting slide rail with a well guard at the upper end and a positioning block at the lower end. The ultrasonic sensor group includes an ultrasonic sensor and a connecting rail one. There is at least one ultrasonic sensor. All ultrasonic sensors are installed on a connecting rail one to form an ultrasonic sensor group. The connecting rail one of the ultrasonic sensor group is inserted into the mounting slide rail. The mounting slide rail and the connecting rail one match each other. The connecting rail one is located on the mounting slide rail between the well guard and the positioning block. The utility model is very convenient for the installation, maintenance and repair of the ultrasonic sensor group through the mounting slide rail with the well guard, making it very easy to align the sensors on both sides of the channel.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: in actual application, it is inconvenient to perform positioning operations on them, which makes it difficult to increase their sealing properties subsequently, and is inconvenient for subsequent normal use, which reduces the efficiency of the sensor and also reduces the convenience of using the sensor. Therefore, we propose a threaded ultrasonic time difference method sensor to solve the above-mentioned problems. Utility Model Content
