an ultrasonic sensor device includes a magnet, a housing, an ultrasonic sensor, and a spring; the shell is a structure with an open front end and a closed rear end, the annular magnet is embedded into the shell, the front end face of the magnet is flush with the front end of the shell, the shape of the inner ring of the magnet is matched with that of the ultrasonic sensor, the ultrasonic sensor is arranged in the magnet and can freely move in the magnet, the spring is arranged between the ultrasonic sensor and the side wall of the rear end of the shell, the ultrasonic sensor extends out of the front end of the shell under the condition that the spring freely extends, a through hole is formed in the side wall of the rear end of the shell, and a lead of the ultrasonic sensor penetrates through the through hole to be connected with external equipment.
Furthermore, two ends of the spring are respectively connected with the rear end of the ultrasonic sensor and the side wall of the rear end of the shell.
Further, three springs are symmetrically disposed along the housing axis.
Further, the outer diameter of the ultrasonic sensor is smaller than the inner diameter of the annular magnet.
Furthermore, the shape of the ultrasonic sensor is circular, the shell is of a cylindrical structure with an open front end and a closed rear end, and the magnet is annular.
Further, the magnet is a strong neodymium magnet or a ferrite magnet.
The utility model discloses has following effect:
when the device is used, the ultrasonic sensor device is attached to the surface of tested equipment through the magnet, the local discharge test work is carried out by one person originally holding the sensor, the mode of operating the local discharge detector by one person is changed into the mode of automatically attaching the sensor to the surface of the tested equipment, and the mode of operating the local discharge detector by one person is changed, so that the number of testers is reduced from 2 to 1. Meanwhile, in the aspect of controlling human errors, the sensor and the spring are combined by combining the elastic force of the spring deformation for a certain time, so that the pressure of the sensor attached to the equipment is consistent every time, interference factors of personnel holding the equipment are reduced, the stability of test data is improved, and the error of the test data is reduced. The utility model discloses make the sensor automatic attached in the equipment surface of being tested to reduce two personnel's coordination time when testing at every turn, because of test data stability improves simultaneously, the error reduces, has reduced the test number of times, and then reduces test time, can maximize improvement work efficiency.

Detailed Description
The technical solution in the embodiments of the present invention is described clearly and completely below.
As shown in fig. 1, the ultrasonic sensor device of the present invention includes a magnet 1, a housing 2, an ultrasonic sensor 3, and a spring 4. The front end of the shell 2 is open, and the rear end is closed. The appearance of the common ultrasonic sensor 3 is matched, the shell 2 is of a cylindrical structure with an open front end and a closed rear end, the annular magnet 1 is embedded into the shell 2, the front end face of the magnet 1 is flush with the front end of the shell 2, and the shape of the inner ring of the magnet 1 is matched with that of the ultrasonic sensor 3. In order to match the circular shape of the ultrasonic sensor 3, the magnet 1 is in a circular ring shape, the ultrasonic sensor 3 is arranged in the circular ring-shaped magnet 1, the outer diameter of the ultrasonic sensor 3 is smaller than the inner diameter of the circular ring-shaped magnet 1, so that the ultrasonic sensor 3 can freely move in the magnet 1, a spring 4 is arranged between the ultrasonic sensor 3 and the side wall of the rear end of the shell 2, and the ultrasonic sensor 3 extends out of the front end of the shell 2 under the condition that the spring is freely stretched. The side wall of the rear end of the shell 2 is provided with a through hole 5, and an ultrasonic sensor lead 6 penetrates through the through hole 5 to be connected with external equipment.
