To more quickly inspect the equipment and pinpoint the location of the ultrasonic transducer damage, a fast and simple system for equipment maintenance needs to be developed. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an ultrasonic transducer group working status detection system.

[0004] The objective of this invention is achieved through the following technical solution: an ultrasonic transducer group working status detection system, comprising an ultrasonic generator connecting base, wherein the ultrasonic generator connecting base connects the ultrasonic generator and a telescopic rod device, an ultrasonic transducer detection probe is provided at the end of the telescopic rod device away from the ultrasonic generator base, and the end of the ultrasonic generator away from the ultrasonic generator base extends into a reaction tank containing a reaction solution; when the system is working, the telescopic rod is controlled to drive the ultrasonic transducer detection probe into the reaction solution and detect the working status of the ultrasonic transducers, locating the position of abnormal transducers.

Detailed Implementation

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] See Figures 1-4This invention provides a technical solution: an ultrasonic transducer group working status detection system, including an ultrasonic generator connecting base 1, the ultrasonic generator connecting base 1 connecting an ultrasonic generator 4 and a telescopic rod device 2, an ultrasonic transducer detection probe 3 being provided at the end of the telescopic rod device 2 away from the ultrasonic generator base 1, and the end of the ultrasonic generator 4 away from the ultrasonic generator base 1 extending into a reaction tank 6, the reaction tank 6 containing a reaction solution 5; when the system is working, the telescopic rod device 2 is controlled to drive the ultrasonic transducer detection probe 3 into the reaction solution 5, and detect the working status of the ultrasonic transducers 11, locating the position of abnormal transducers.

[0020] In this embodiment, as Figure 1 As shown, when the ultrasonic transducer detection probe 3 is not working, it will remain above the liquid surface to prevent the solution from corroding the equipment. Every certain period of time, the probe will enter the solution under the control of the lifting rod and move back and forth from top to bottom 3 times. The data monitored by the eddy current detection probe will be used to determine whether the transducer is working normally. If there is a large fluctuation, the location of the abnormal transducer can be quickly located, which will facilitate inspection and maintenance.

[0021] In some embodiments, the ultrasonic transducer detection probe 3 includes an ultrasonic transducer structure and a detection circuit, wherein the detection circuit is disposed on the ultrasonic transducer structure; the ultrasonic transducer structure includes an ultrasonic transducer 11 and a thermistor 12, wherein each ultrasonic transducer 11 is provided with a thermistor 12. When the system is working, the microcontroller collects the heat information of the ultrasonic transducer 11 detected by the thermistor 12. When the temperature is not within the preset temperature range, the temperature of the target ultrasonic transducer 11 is considered to be abnormal.

[0022] In this embodiment, a thermistor is fixed to each oscillator. A microcontroller collects the heat information monitored by the thermistor and displays the heat changes during oscillator operation on a terminal display. When the oscillator is working normally, its internal resistance steadily generates heat, maintaining a constant temperature range, and the heat information monitored by the thermistor is stable. When the oscillator malfunctions, the internal heat changes drastically, the temperature deviates from the normal range, and the data monitored by the thermistor changes significantly. The microcontroller collects data to monitor whether the oscillator is working normally. Figure 2 As shown, by directly attaching the thermistor to the ultrasonic transducer, the transducer's operating status can be directly monitored. The heat information monitored by the thermistor is collected by connecting it to a microcontroller via a serial bus and displayed directly on a monitor.

[0023] In some embodiments, the detection circuit includes a first detection circuit or a second detection circuit, used to detect the circuit operation of the ultrasonic transducer 11 and generate operating status information by combining thermal information.

[0024] In some embodiments, the first detection circuit includes multiple parallel ultrasonic transducer elements us forming multiple branches, and each branch has an ultrasonic transducer element us connected in series with a fuse; each branch is also provided with a branch meter v. When the ultrasonic transducer element us is broken down by current, the fuse blows, causing a short circuit in the branch, and the location of the ultrasonic transducer element us that is short-circuited is determined by the branch meter v.

[0025] In this embodiment, after all the ultrasonic transducer elements us are connected in parallel to the circuit, a fuse is connected in series in each branch. The fuse operates by melting its own heat after the current exceeds a specified value for a certain period of time, thus breaking the circuit. When the ultrasonic transducer element us is broken down by a large current, the fuse melts quickly due to its ampere-second characteristic, causing a short circuit in that branch. The location of the short-circuited transducer can then be quickly determined using a branch meter. Figure 3 The diagram shows the circuits of two branches. In actual installation, the meter should be installed outside the equipment cavity and connected to the central control console to monitor the circuit operation.

[0026] In some embodiments, the second detection circuit includes multiple parallel ultrasonic transducer elements us forming multiple branches. Each branch has an ultrasonic transducer element us connected in series with a fixed resistor R. The working status of the ultrasonic transducer element us is determined by detecting whether there is current in the fixed resistor R.

[0027] In this embodiment, as Figure 4 As shown, an ultrasonic transducer element us is connected in series with a fixed resistor R to form a unit, and multiple units are connected in parallel into the circuit. A motor controls the telescopic rod device 2, allowing the ultrasonic transducer detection probe 3 to rise and fall freely. Utilizing the principles of eddy current detection and electromagnetic induction, the relative movement of the resistor and the eddy current probe causes significant changes in the current within the resistor, which in turn significantly affect the magnetic field. The transducer's operational status is determined by detecting whether current flows through the resistor. Under normal operating conditions, the current through the resistor is constant. When the transducer is open-circuited, no current flows through the resistor, affecting the eddy current in its normal state. When the transducer is short-circuited due to a large current, the resistor protects the circuit, and the increased current through the resistor alters the magnetic field. The probe can detect these changes in current within the resistor, thus determining whether the transducer is operating normally.

[0028] In some embodiments, the microcontroller displays heat information via a display screen.

[0029] In some embodiments, the telescopic rod device 2 is raised and lowered by a motor.

It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
