Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic level gauges, and specifically to an integrated ultrasonic level gauge. Background Technique

[0002] The core feature of an intelligent sensor is the integrated integration of sensing, processing, communication, and control. The integrated ultrasonic level gauge fully follows this technical framework. The working principle of an ultrasonic level gauge is that an ultrasonic pulse is emitted by a transducer, reflected back when it encounters the surface of the measured medium, and part of the reflected echo is received by the transducer, converted into an electrical signal through a piezoelectric crystal or a magnetostrictive device, and the distance from the sensor to the surface of the measured liquid is calculated based on the time between the emission and reception of the sound wave. Due to the non-contact measurement, the measured medium is hardly restricted and can be widely used for measuring the heights of various liquids and solid materials.

[0003] When an ultrasonic level gauge is in use, for the reasons of ensuring measurement accuracy and avoiding false echoes, it should strictly comply with the installation specification that the emitting surface of the transducer is parallel to the measured liquid surface to ensure the perpendicular emission of the sound wave. However, in some scenarios (such as container structure limitations or the need to avoid interference factors such as the feeding port and obstacles), the existing ultrasonic level gauges do not have an angle adjustment function and cannot adjust the probe orientation to reduce errors, thereby affecting the applicability and measurement accuracy of the sensor. Summary of the Invention

[0006] Further, an angle adjustment component is provided on the outer edge of the bottom of the ball seat. The angle adjustment component includes X-axis ear plates fixed to the left and right sides of the outer edge of the ball seat. A motor one is bolted to the side end of the X-axis ear plate, and the rotating end of the motor one is fixedly connected to an X-axis crank.

[0007] Further, the angle adjustment component further includes Y-axis ear plates fixed to the front and rear ends of the outer edge of the ball seat. A motor two is bolted to the side end of the Y-axis ear plate, and the rotating end of the motor two is fixedly connected to a Y-axis crank.

[0008] Furthermore, the X-axis crank arm and the Y-axis crank arm are arranged alternately up and down, and the middle parts of the X-axis crank arm and the Y-axis crank arm are provided with hollow arc grooves that are engaged with the outlet pipe.

[0009] Furthermore, the end ring is fixedly installed at the bottom of the body, and the body has a built-in controller, and the side end of the controller is connected to a wiring terminal.

[0010] Furthermore, a connecting cable is connected to the top of the controller, and one end of the connecting cable facing away from the controller is electrically connected to the display screen, and the display screen is embedded in the end cover of the body.

A signal line is connected to the top of the transducer, and the signal line axially passes through the outlet pipe and is electrically connected to a corresponding module of the controller.

[0012] Furthermore, a rotating pin is fixedly installed on the side end of the probe opening, and a cover plate is rotatably installed inside the rotating pin, and both ends of the cover plate pin shaft are elastically connected to the inner wall of the rotating pin through a torsion spring.

[0014] Furthermore, the position adjustment assembly also includes a mounting back plate fixedly mounted on the top of the root of the U-shaped seat, the mounting back plate is fixed to the inner wall of the container by bolts, and a telescopic rod is fixedly connected to the inner wall of the recess of the mounting back plate, and the telescopic end of the telescopic rod is hinged to the connecting pin at the side end of the end ring.

[0015] The present invention provides an integrated ultrasonic level meter, which has the following beneficial effects:

[0016] 1. During the use of the present invention, a universal moving component is added as a connecting piece at the joint between the body and the probe of the ultrasonic level gauge of the present application. On the one hand, the Y-axis crank arm connected to the rotating end of the second motor drives the slider coaxial with the middle part of the wire outlet pipe to slide within the gap on the opposite side of the sphere. On the other hand, the X-axis crank arm connected to the rotating end of the first motor drives the sphere itself to rotate at the bottom of the frustum-shaped movable groove inside the ball seat through the wire outlet pipe, enabling the sphere to move freely in the X and Y axes directions, coordinating to adjust the output angle of the probe. In special application scenarios where the container structure is restricted, it can always ensure that the emitting surface of the transducer in the probe is parallel to the measured object to ensure the vertical emission of sound waves.

[0017] 2. During the use of the present invention, by hinging the connecting pin at the side end of the end ring with the telescopic end of the telescopic rod, the end ring is guided to slide within the side grooves on both sides of the notch of the U-shaped seat under the push of the telescopic rod, so that the end ring and the body and the probe connected to its upper and lower ends can penetrate into the container, avoiding the liquid inlet and outlet on both sides of the container or possible obstacles, thus preventing the scattering caused by the bubbles, turbulence or surging generated when the material flows through the liquid inlet and outlet and the interference signal formed after the sound wave is reflected due to the existence of the obstacle. In addition, a reset support plate is installed at the initial position of the U-shaped seat near the inner wall of the container. It can not only play a dust-proof role by squeezing the cover plate with the reset support plate during idle time, but also enable the cover plate covering the bottom of the probe to be automatically opened into the working state under the action of the torsion spring force after the probe breaks away from the reset support plate, realizing the protection of the ultrasonic level gauge of the present application during idle time without adding additional power mechanisms, making the linkage of each structure between the devices stronger and having stronger applicability.

[0026] The following further describes in detail the implementation manners of the present invention with reference to the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention

[0027] Please refer to Figures 5 to 7 , the present invention provides a technical solution: an integrated ultrasonic level gauge, including a universal moving component 1. The universal moving component 1 includes an end ring 101 provided at the top of the universal moving component 1. A connecting pin 102 is integrally fixed to the side end of the end ring 101, and a ball seat 103 is fixedly installed at the bottom of the end ring 101. A frustum-shaped activity groove 104 is opened inside the ball seat 103, and a damping layer 105 is attached to the bottom opening of the activity groove 104. A sphere 2 is rotatably installed inside the damping layer 105. The sphere 2 is composed of two hemispheres and connecting ribs on both sides of the opposite surfaces. A slide block 3 is slidably installed in the gap between the opposite surfaces of the sphere 2, and a wire outlet pipe 4 is embedded in the middle of the slide block 3. And the axis of the wire outlet pipe 4 coincides with the center of the sphere 2. An angle adjustment component 5 is provided at the outer edge of the bottom of the ball seat 103. The angle adjustment component 5 includes X-axis ear plates 501 fixed to the left and right sides of the outer edge of the ball seat 103. A motor 1 502 is bolted to the side end of the X-axis ear plate 501, and the rotating end of the motor 1 502 is fixedly connected to an X-axis crank 503. The angle adjustment component 5 further includes Y-axis ear plates 504 fixed to the front and rear ends of the outer edge of the ball seat 103. A motor 2 505 is bolted to the side end of the Y-axis ear plate 504, and the rotating end of the motor 2 505 is fixedly connected to a Y-axis crank 506. The X-axis crank 503 and the Y-axis crank 506 are arranged up and down in a staggered manner, and hollow arc-shaped grooves for clamping and cooperating with the wire outlet pipe 4 are provided in the middle of both the X-axis crank 503 and the Y-axis crank 506;

[0028] The specific operation is as follows: the connecting pin 102 at the side end of the end ring 101 is hinged with the telescopic end of the telescopic rod 1605, so that the telescopic rod 1605 pushes the lower end ring 101 to slide in the side grooves 1602 on both sides of the notch of the U-shaped seat 1601, so that the end ring 101 and the body 6 and the probe 11 connected to the upper and lower ends of the end ring 101 can penetrate into the container, avoiding the inlet and outlet ports on both sides of the container or possible obstacles, thereby preventing the bubbles generated when the material flows at the inlet and outlet ports, the scattering caused by turbulence or surging, and the existence of obstacles, which will cause interference after the sound wave is reflected. Signal, in addition, the U-shaped seat 1601 is equipped with a reset support plate 1603 at the initial position near the inner wall of the container, which can not only squeeze the cover plate 15 by the reset support plate 1603 when idle, so that the cover plate 15 can shield the bottom of the probe 11 to prevent dust, but also make the probe 11 automatically open and enter the working state under the action of the torsion spring elastic force after it is separated from the reset support plate 1603, without adding an additional power mechanism, so that the protection of the ultrasonic level meter of the present application can be realized when idle, so that the linkage between the structures of the device is stronger and has stronger applicability;

[0029] See also Figures 1 to 4 , the end ring 101 is fixedly installed at the bottom of the body 6, and the body 6 has a built-in controller 7, and the side end of the controller 7 is connected to a wiring terminal 8, the top of the controller 7 is connected to a connecting cable 9, and the end of the connecting cable 9 away from the controller 7 is electrically connected to a display screen 10, and the display screen 10 is embedded in the end cover of the body 6, the bottom of the outlet pipe 4 is fixedly connected to a probe 11, and the probe 11 has a built-in transducer 12, the top of the transducer 12 is connected to a signal line 13, and the signal line 13 axially passes through the outlet pipe 4 and is electrically connected to the corresponding module of the controller 7;

[0030] The specific operation is as follows: the ultrasonic level meter of the present application is provided with a universal movable assembly 1 as a connecting piece at the junction of the body 6 and the probe 11. When in use, the transducer 12 in the probe 11 emits an ultrasonic pulse, which is reflected back when encountering the surface of the measured medium. Part of the reflected echo is received by the transducer 12 and converted into an electrical signal through a piezoelectric crystal or a magnetostrictive device. The signal is further transmitted to the controller 7 through a signal line 13 running through the outlet pipe 4 for further processing. The distance from the probe 11 to the surface of the measured liquid is calculated by the time between the emission and reception of the sound wave and displayed in real time through the display screen 10;

[0031] See also Figures 2 to 3, a rotating pin 14 is fixedly installed at the open side end of the probe 11, a cover plate 15 is rotatably installed inside the rotating pin 14, and both ends of the pin shaft of the cover plate 15 are elastically connected to the inner wall of the rotating pin 14 through torsion springs. The end ring 101 is slidably installed inside the position adjusting assembly 16. The position adjusting assembly 16 includes a U-shaped seat 1601 surrounding the outer side of the end ring 101. Side grooves 1602 are formed at both ends of the notch of the U-shaped seat 1601, and the side grooves 1602 are slidably matched with the outer edge of the end ring 101. A reset support plate 1603 with an "L" shape is fixedly connected to the bottom end of the root of the U-shaped seat 1601, and the extension plate at the bottom of the reset support plate 1603 is in abutting cooperation with the cover plate 15. The position adjusting assembly 16 further includes a mounting back plate 1604 fixedly installed at the top end of the root of the U-shaped seat 1601. The mounting back plate 1604 is fixed to the inner wall of the container by bolts, and a telescopic rod 1605 is fixedly connected to the inner wall of the notch of the mounting back plate 1604. The telescopic end of the telescopic rod 1605 is hinged to the connecting pin 102 at the side end of the end ring 101;

[0032] The specific operation is as follows. Through the cooperation of the universal moving assembly 1 and the angle adjusting assembly 5, on the one hand, the Y-axis crank 506 connected to the rotating end of the motor two 505 drives the slider 3 coaxial with the middle part of the wire outlet pipe 4 to slide in the gap on the opposite side of the sphere 2. On the other hand, the X-axis crank 503 connected to the rotating end of the motor one 502 drives the sphere 2 itself to rotate at the bottom end of the frustum-shaped movable groove 104 inside the ball seat 103 through the wire outlet pipe 4. In this application, the sphere 2 is designed as a spherical structure composed of two hemispheres and connecting ribs on both sides of the opposite surface. With the structural design of the X-axis crank 503 and the Y-axis crank 506 that are staggered up and down and are clamped and matched with the wire outlet pipe 4, the sphere 2 can move freely in the X and Y axis directions, and the output angle of the probe 11 can be adjusted accordingly. In special application scenarios where the container structure is restricted, it can always ensure that the emitting surface of the transducer 12 in the probe 11 is parallel to the measured object, so as to ensure the vertical emission of sound waves, and solve the problem that the interference signal formed under non-vertical angles in the traditional ultrasonic level gauge due to the fixed installation angle affects the normal operation of the level gauge.

[0033] It is worth supplementing and explaining that: during the process of resetting the ultrasonic level gauge of this application from the working state to the idle state, under the control of the angle adjusting assembly 5 on the wire outlet pipe 4 inside the sphere 2, the probe 11 needs to be reset to a state where it coincides with the axis of the body 6, so as to avoid the situation that the bottom cover plate 15 of the probe 11 does not contact the reset support plate 1603 and fails to achieve the automatic reset effect.

[0034] In summary, when using this integrated ultrasonic level gauge:

[0035] First, by hinging the connecting pin 102 at the side end of the end ring 101 with the telescopic end of the telescopic rod 1605, the end ring 101 is guided to slide in the side grooves 1602 on both sides of the notch of the U-shaped seat 1601 under the push of the telescopic rod 1605. As a result, the end ring 101 and the body 6 and the probe 11 connected to its upper and lower ends can penetrate into the container, avoiding the liquid inlet and outlet on both sides of the container or possible obstacles. Furthermore, it can prevent the scattering caused by the bubbles, turbulence or surging generated when the material flows through the liquid inlet and outlet and the interference signal formed after the sound wave is reflected by the obstacle. In addition, a reset support plate 1603 is installed at the initial position of the U-shaped seat 1601 near the inner wall of the container. Not only can the cover plate 15 be shielded from dust by squeezing the cover plate 15 with the reset support plate 1603 during idle time, but also after the probe 11 is separated from the reset support plate 1603, the cover plate 15 covering the bottom of the probe 11 can be automatically opened under the action of the torsion spring force to enter the working state. The protection of the ultrasonic level gauge of the present application during idle time can be achieved without adding an additional power mechanism, making the linkage of each structure between devices stronger and having stronger applicability;

[0036] Secondly, a universal movable component 1 is added as a connecting part at the joint of the body 6 and the probe 11 of the ultrasonic level gauge of the present application. During use, the transducer 12 in the probe 11 emits ultrasonic pulses, which are reflected back when encountering the surface of the measured medium. Part of the reflected echo is received by the transducer 12 and converted into an electrical signal through a piezoelectric crystal or a magnetostrictive device. The signal is further transmitted to the controller 7 through the signal line 13 passing through the wire outlet pipe 4 for further processing. The distance from the probe 11 to the surface of the measured liquid is calculated based on the time between the emission and reception of the sound wave and is displayed in real time through the display screen 10;

[0037] Finally, through the cooperation of the universal moving component 1 and the angle adjustment component 5, on the one hand, the Y-axis crank 506 connected to the rotating end of the second motor 505 drives the slider 3 coaxial with the middle part of the wire outlet pipe 4 to slide within the gap on the opposite side of the sphere 2. On the other hand, the X-axis crank 503 connected to the rotating end of the first motor 502 drives the sphere 2 itself to rotate at the bottom end of the frustum-shaped movable groove 104 inside the ball seat 103 through the wire outlet pipe 4. In this application, the sphere 2 is designed as a spherical structure composed of two hemispheres and connecting ribs on both sides of the opposite surface. With the structural design of the X-axis crank 503 and the Y-axis crank 506 that are staggered up and down and clamped with the wire outlet pipe 4, the sphere 2 can move freely in the X and Y axis directions, and cooperate to adjust the output angle of the probe 11. In special application scenarios where the container structure is restricted, it can always ensure that the emitting surface of the transducer 12 in the probe 11 is parallel to the object to be measured, so as to ensure the vertical emission of sound waves, and solve the deficiency that in the traditional technology, the ultrasonic level gauge is affected by the interference signal formed under non-vertical angles due to the fixed installation angle, which affects the normal operation of the level gauge. In practical applications, by simulating the possible interference paths at different angles through algorithms, analyzing the time series of the echo signals, identifying the abnormal time intervals of multiple reflections, avoiding the areas prone to false echoes, and combining with the three-dimensional model of the container, the installation angle that meets the requirements of vertical emission is automatically generated, and then the emitting angle of the probe 11 is automatically corrected through the cooperation of the universal moving component 1 and the angle adjustment component 5, meeting the intelligent application requirements of the ultrasonic level gauge of this application.
