Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

The utility model relates to an open ultrasonic matrix flowmeter sensor suite which is used for installing an ultrasonic sensor.

As shown in fig. 1, 2, 3 and 4, the sensor kit first comprises an ultrasonic sensor 6. And further comprises a universal ball 5 with a mounting hole. The ultrasonic sensor 6 is mounted in the mounting hole of the universal ball 5. The universal ball 5 has a spherical structure.

The working end of the ultrasonic sensor 6 is exposed through the mounting hole, and can transmit and receive ultrasonic signals. The other end of the ultrasonic sensor 6 is pressed by a jack post 8, and is mounted and fixed in the mounting hole of the universal ball 5 by the pressing of the jack post 8. Then, a pressing plate 9 is fixedly arranged on the surface of the lower end face corresponding to the mounting hole of the universal ball 5, and the jacking column 8 is jacked and fixed by using the pressing plate 9; thereby achieving a fixed mounting for the ultrasonic sensor 6.

The ultrasonic sensor 6 has a wire for transmitting a signal, which is exposed after passing through the top post 8 and the pressing plate 9. The center of the top column 8 is provided with a hole along the length direction, and the surface of the pressing plate 9 is provided with a hole. The pressing plate 9 is fixedly connected with the universal ball 5 by using a second fixing screw 8.

In the present utility model, the ball 5 is rotatably mounted in the housing 1, which means that it can be rotated when required, but is stationary in the operating state. Correspondingly, a cover plate 3 is fixedly arranged on the surface of the shell 1, and the cover plate 3 is detachable. The cover plate 3 is provided with a round hole on the surface, after the installation, the cover plate 3 presses the universal ball 5, and the upper part of the universal ball 5 is positioned in the round hole of the cover plate 3. The cover plate 3 can prevent the universal ball 5 from moving.

In a specific implementation, the jack-prop 8 is preferably a rubber column made of rubber, so that the jack-prop 8 flexibly supports and fixes the ultrasonic sensor 6, and the damage of the rigid structure to the sensor structure is avoided.

The universal ball 5 of the present utility model can be rotatably adjusted in the housing 1 to change the direction of the ultrasonic sensor 6. When rotation adjustment is needed, the cover plate 3 is loosened. To facilitate the rotation of the ball 5, a number of adjustment holes 10 are typically provided in the surface of the ball 5. During adjustment, the universal ball orientation is adjusted using the post inserted into the adjustment aperture 10.

As shown in fig. 1, the ball 5 is mounted in the housing 1, and preferably, a hole is formed in the bottom of the mounting position of the ball 5 on the housing 1, so that the contact position of the ball 5 with the housing 1 is in line contact. At the same time, the contact position of the cover plate 3 and the universal ball 5 is also in line contact. The universal ball 5 and the shell 1 and the cover plate 3 form two line contacts together, so that the resistance of the universal ball 5 in the rotation adjustment process can be reduced.
