Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic waves, in particular to an external power supply device for ultrasonic instruments. Background Art

[0002] Ultrasound is a type of sound wave with a frequency exceeding 20,000 Hz. It has excellent directionality, strong penetrating power, and can easily generate concentrated sound energy. It can travel long distances in water and is used for distance measurement, speed measurement, cleaning, welding, stone crushing, and sterilization. It has numerous applications in medicine, military affairs, industry, and agriculture. Ultrasound gets its name from the fact that its lower frequency limit is greater than the upper limit of human hearing.

[0003] Existing ultrasonic metering systems typically use disposable batteries, while 485 circuits utilize batteries. Conventional 485 circuits offer long communication distances and strong bus interference immunity. However, this solution can only power the 485 system alone and cannot power the ultrasonic metering system. Furthermore, power supply noise from the 485 circuit can interfere with the ultrasonic metering system, leading to data discrepancies and cost disputes. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the 485 circuit in the prior art, such as long communication distance and strong bus anti-interference ability, and the power supply noise of the 485 circuit will interfere with the ultrasonic measurement system, resulting in data deviation and cost disputes, and to propose an external power supply device for ultrasonic instruments.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An external power supply device for an ultrasonic instrument includes a protective housing, the top of the protective housing being open, a rectangular cavity being formed on both sides of the protective housing, a plurality of ventilation holes being formed on an inner wall of one side of the rectangular cavity, a 485 module and a battery being disposed within the protective housing, an isolated power supply module being disposed at both the input and output ends of the 485 module, and the battery being electrically connected to the isolated power supply module at the input end of the 485 module;

[0007] A first filter plate is clamped inside the rectangular cavity, and a cleaning component for cleaning the surface of the first filter plate is provided on one side of the first filter plate;

[0008] A braking assembly for braking the first filter plate is provided on the top of the protective shell.

[0009] In one possible design, the cleaning assembly includes two symmetrically arranged side blocks fixedly connected to one side of the first filter plate, a slide groove is provided on one side of the side block, a slider is slidably connected inside the slide groove, a same spring is fixedly connected between the bottom of the slider and the bottom inner wall of the slide groove, a same strip plate is fixedly connected between the two sliders, and a plurality of bristles are provided on one side of the strip plate.

[0010] In one possible design, the brake assembly includes a cover plate arranged on the top of the protective shell, the top of the protective shell is provided with two symmetrically arranged vertical holes, both sides of the bottom of the cover plate are fixedly connected with vertical plates, the vertical plates pass through the vertical holes, the bottom of one side of the vertical plate is fixedly connected with a horizontal plate, the bottom of the horizontal plate is fixedly connected with two symmetrically arranged clamping rods, a vertical groove is provided on one side of the first filter plate, the vertical groove is used in conjunction with the vertical plate, a connected horizontal groove is provided on the inner wall of one side of the vertical groove, a clamping groove is provided on the bottom inner wall of the horizontal groove, the clamping groove is engaged with the clamping rod, and the horizontal plate is used in conjunction with the horizontal groove.

[0011] In a possible design, two symmetrically arranged grooves are provided on the top of the cover plate, and a same U-shaped handle is rotatably connected between the inner walls on both sides of the grooves.

[0012] In a possible design, a rectangular hole is opened at the bottom of the protective shell, and two symmetrically arranged second filter plates are arranged on the inner wall of the bottom of the protective shell.

[0013] In a possible design, mounting plates are fixedly connected to both sides of the protective shell, and two symmetrically arranged mounting holes are opened inside the mounting plates.

[0014] In this application, when the ultrasonic instrument is powered by an external power supply, the disposable battery output is automatically turned off to extend the battery life. The internal isolation power module of Jinshengyang B0505 ​​is isolated from the battery and 485 module to ensure the accuracy of the measurement data.

[0015] During normal use, the ventilation holes can achieve ventilation effects. The setting of the first filter plate can prevent dust from entering the interior of the device. At the same time, the rectangular holes reserved below and the second filter plate can ventilate from below, thereby improving the ventilation effect and preventing the device from overheating.

[0016] When you need to clean the first filter plate, you can press the strip plate vertically downward, and the strip plate drives multiple bristles to move vertically downward, at this time you can remove dust on the surface of the bristles, and at the same time the strip plate drives the slider downward, the slider moves inside the slide groove and squeezes the spring, and can rebound quickly after reaching the lowest point, thereby improving cleaning efficiency;

[0017] When the mounting hole needs to be disassembled, the U-shaped handle needs to be turned out from the inside of the groove first, and the cover plate needs to be lifted for a distance. At this time, the cover plate drives the vertical plate to move up, and the vertical plate drives the clamping rod and the horizontal plate to move up. The clamping rod moves out from the inside of the clamping groove, and the horizontal plate conflicts with the top inner wall of the horizontal groove, releasing the braking state of the first filter plate. The cover plate can be moved out only after the first filter plate is moved horizontally to avoid shaking that causes the cover plate and the first filter plate to fall off, thereby ensuring the stability of the device.

[0018] Beneficial effects: Energy management optimization: Through design, ultrasonic instruments can automatically shut down the output of disposable batteries when using external power supply. This function effectively avoids unnecessary discharge of batteries, significantly extends the battery life, reduces users' operation and maintenance costs, and also embodies the design concept of environmental protection and energy saving.

[0019] Data accuracy assurance: The internally used Jinshengyang B0505 ​​isolated power supply module not only achieves electrical isolation from the external power supply and 485 module, but also effectively prevents the impact of external interference on the measurement data, ensuring the accuracy and reliability of the measurement data, which is particularly important for application scenarios requiring high-precision measurement.

[0020] Efficient heat dissipation and protection: The design of the ventilation holes combined with the use of the first and second filter plates not only improves the ventilation effect of the device and effectively avoids performance degradation or damage caused by excessive internal temperature, but the first filter plate can also effectively block dust from entering, protecting internal electronic components from contamination, and improving the stability and service life of the equipment.

[0021] Convenient maintenance and cleaning: The innovative cleaning mechanism moves the bristles downward by pressing the strip plate to remove dust, and combined with the rebound effect of the spring, the cleaning process is more efficient and labor-saving, reducing the complexity and time cost of maintenance work and improving the user experience.

[0022] Safe and stable disassembly and assembly design: The unique disassembly and installation hole design, through the clever coordination of the U-shaped handle, cover plate, vertical plate, clamping rod and horizontal plate, realizes the stable locking and convenient release of the first filter plate, which not only ensures the stability of the device during operation, but also facilitates the user to replace and maintain the filter plate, enhancing the flexibility and maintainability of the equipment.
