Description

Technical Field

[0001] This utility model relates to the field of ultrasonic instrument technology, and in particular to a corrosion-resistant ultrasonic instrument. Background Technology

[0002] An ultrasonic level gauge is a digital level instrument controlled by a microprocessor. During measurement, ultrasonic pulses are emitted by a sensor, and the sound waves are reflected by the liquid surface and received by the same sensor. The signals are converted into electrical signals by a piezoelectric crystal, and the distance from the sensor to the surface of the measured liquid is calculated from the time between the emission and reception of the sound waves. A utility model patent with patent number CN217585962U and patent title "An Ultrasonic Level Gauge Waterproofing Device" includes a mounting base, an instrument body fixedly mounted on top of the mounting base, an instrument display screen fixedly embedded on top of the instrument body, a waterproofing mechanism, and a drying mechanism. The waterproofing mechanism includes a water tank, a glass plate, and a water outlet pipe. The top of the glass plate is convex, and the bottom of the glass plate is fixedly mounted on top of the instrument body. The water tank is fixedly mounted on top of the mounting base and on one side of the instrument body.

[0003] However, the aforementioned ultrasonic level gauge anti-leakage device still has certain drawbacks in some applications: Firstly, the device uses an electric telescopic rod to move a sponge cloth to wipe the glass plate surface, which is not only complex in structure and power source, but also the wiping effect on the glass plate surface is not ideal. Secondly, the device uses a heating wire to heat the dried material, thereby absorbing moisture on the inner wall of the glass plate; however, this technical solution does not solve the problem of water ingress onto the instrument display surface. Therefore, a targeted ultrasonic instrument device is proposed to address these shortcomings. Summary of the Invention

[0004] This invention overcomes the shortcomings of the prior art and provides a corrosion-resistant ultrasonic instrument device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a corrosion-resistant ultrasonic instrument device, comprising: an ultrasonic sensor mounted on a flange, the ultrasonic sensor being disposed inside a tank, an instrument display screen being mounted on the upper part of the ultrasonic sensor, the instrument display screen being disposed outside the tank, a protective sleeve being mounted on the flange, and the instrument display screen being fixed inside the protective sleeve; a spherical glass plate being mounted on the upper part, a sealing gasket being integrally mounted on the bottom surface of the glass plate, the inner circumferential side of the sealing gasket being attached to the outer circumferential side of the instrument display screen, and a cleaning component being mounted in the middle of the glass plate.

[0006] In a preferred embodiment of the present invention, the cleaning component includes: a rotating shaft rotatably disposed in the middle of the glass plate, an elastic lever disposed on one side of the rotating shaft, and a rubber scraper disposed on the other end of the elastic lever.

[0007] In a preferred embodiment of this utility model, the rotating shaft is connected to the middle part of the top surface of the instrument display screen via a rotating rod, and the rotating shaft is connected to the middle part of the top surface of the instrument display screen via a torsion spring.

[0008] In a preferred embodiment of this utility model, a winding wheel is provided at the upper end of the rotating shaft, and the winding wheel is connected to the pull rod through a pull rope.

[0009] In a preferred embodiment of this utility model, a water baffle is integrally provided on the upper part of the rotating shaft, and the bottom surface of the water baffle is in contact with the top surface of the glass plate.

[0010] In a preferred embodiment of this utility model, the outer periphery of the instrument display screen and the protective sleeve are combined to form a water storage tank, and a plurality of drainage holes are arrayed on the bottom surface of the water storage tank.

[0011] In a preferred embodiment of this utility model, a plurality of elastic positioning plates are arranged in an array on the bottom surface of the glass plate, and the elastic positioning plates are in contact with the outer peripheral side of the sealing gasket.

[0012] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0013] (1) This utility model uses a manual pull rod to drive the rotating shaft to rotate via a pull rope. The rotating shaft drives the elastic lever to rotate around the rotating shaft, thereby cleaning the dust and water stains on the glass plate surface during the rotation of the rubber scraper. Compared with the method of driving the oil cylinder to move the sponge cloth, the cleaning efficiency is higher and the cleaning effect is better. On the other hand, after each release of the pull rod, the rotating shaft will return to the initial state under the action of the torsion spring, thereby driving the scraper to circulate and scrape the glass plate surface, further improving the cleaning effect.

[0014] (2) This utility model uses a sealing gasket to cover the glass plate on the instrument display screen, which improves the sealing performance of the instrument display screen. Furthermore, the sealing gasket is clamped by an elastic positioning plate, which further prevents atomized water from entering the instrument display screen, thus achieving a preventive effect. No special drying treatment is required afterward, and the corrosion resistance is better. Moreover, it can be flexibly installed and disassembled, which is convenient for later maintenance and cleaning. Attached Figure Description

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] like Figure 1 and Figure 2 As shown, an anti-corrosion ultrasonic instrument device includes: an ultrasonic sensor 1 mounted on a flange 3, the ultrasonic sensor 1 being installed inside a tank (not shown in the figure), an instrument display screen 2 mounted above the ultrasonic sensor 1, the instrument display screen 2 being installed outside the tank, a protective sleeve 4 mounted on the flange 3, and the instrument display screen 2 being fixed inside the protective sleeve 4; a spherical glass plate 6 being mounted on the upper part, with a sealing gasket 7 integrally mounted on the bottom surface of the glass plate 6, the inner circumferential side of the sealing gasket 7 fitting against the outer circumferential side of the instrument display screen 2. The sealing gasket 7 covers the instrument display screen 2 with the glass plate 6, improving the sealing performance of the instrument display screen 2.

[0024] like Figure 4 and Figure 5As shown, in a preferred embodiment of this invention, several elastic positioning plates 18 are arrayed on the bottom surface of the glass plate 6. The elastic positioning plates 18 are in contact with the outer peripheral side of the sealing gasket 7. The sealing gasket 7 is clamped by the elastic positioning plates 18, further preventing atomized water from entering the instrument display screen 2, thus achieving a preventive effect. No special drying treatment is required afterward, resulting in better corrosion resistance. Moreover, it can be flexibly installed and disassembled, facilitating later maintenance and cleaning. On the other hand, the bottom of the sealing gasket 7 is treated with a raised edge to facilitate better fitting of the sealing gasket 7 onto the outer peripheral side of the instrument display screen 2.

[0025] like Figure 3 As shown, in a preferred embodiment of this utility model, a cleaning assembly is provided in the middle of the glass plate 6. The cleaning assembly includes: a rotating shaft 8 rotatably disposed in the middle of the glass plate 6; an elastic lever 9 disposed on one side of the rotating shaft 8; a rubber scraper 10 disposed on the other end of the elastic lever 9; and a winding wheel 13 disposed at the upper end of the rotating shaft 8. The winding wheel 13 is connected to a pull rod 14 via a pull rope 5. By manually pulling the pull rod 14, the pull rod 14 drives the rotating shaft 8 to rotate via the pull rope 5. The rotating shaft 8 drives the elastic lever 9 to rotate around the rotating shaft 8, thereby cleaning the dust and water stains on the surface of the glass plate 6 during the rotation of the rubber scraper 10. Compared with the method of driving a hydraulic cylinder to move a sponge cloth, the cleaning efficiency is higher and the cleaning effect is better.

[0026] In a preferred embodiment of this invention, the rotating shaft 8 is connected to the middle part of the top surface of the instrument display screen 2 via a rotating rod 11, and the rotating shaft 8 is also connected to the middle part of the top surface of the instrument display screen 2 via a torsion spring 12. Each time the pull rod 14 is released, the rotating shaft 8 will return to its initial state under the force of the torsion spring 12, thereby driving the scraper to circulate and scrape the surface of the glass plate 6, further improving the cleaning effect.

[0027] In a preferred embodiment of this invention, a baffle plate 15 is integrally provided on the upper part of the rotating shaft 8, and the bottom surface of the baffle plate 15 is in contact with the top surface of the glass plate 6. The baffle plate 15 can prevent water from entering the instrument display screen 2 from the connection between the rotating shaft 8 and the glass plate 6. At the same time, the instrument display screen 2 and the protective sleeve 4 are combined to form a water storage tank 16 on the outer periphery. The bottom surface of the water storage tank 16 is provided with a plurality of drainage holes 17, which can drain the water on the surface of the glass plate 6 in a timely manner.

[0028] The working principle of this utility model is as follows: the flange 3 is locked to the flange 3 on the tank body with bolts, the ultrasonic sensor 1 is sealed inside the tank, the instrument display screen 2 is outside the tank, the glass plate 6 is fixed to the outer side of the instrument display screen 2 by the sealing gasket 7, and elastic positioning is used for auxiliary clamping. When it rains, rainwater enters the water storage tank 16 through the glass plate 6 and is discharged through the drain hole 17. When it is necessary to clean the outer surface of the glass plate 6, the pull rod 14 is manually pulled. The pull rod 14 drives the rotating shaft 8 to rotate through the pull rope 5. The rotating shaft 8 drives the elastic lever 9 to rotate around the rotating shaft 8, thereby cleaning the surface of the glass plate 6 during the rotation of the rubber scraper 10. After releasing the pull rod 14, the rotating shaft 8 will return to the initial state under the force of the torsion spring 12, driving the scraper to circulate and scrape the surface of the glass plate 6.

[0029] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
