Description

TECHNICAL FIELD

[0001] The utility model relates to liquid level detection technical field, concretely is a kind of non-contact type tank ultrasonic liquid level meter. BACKGROUND

[0002] The technical core of non-contact type tank ultrasonic liquid level meter is to realize liquid level measurement by ultrasonic signal, and its principle is based on the reflection characteristics of sound waves at the interface between air and liquid. The liquid level meter transmits high-frequency ultrasonic pulses. When the sound waves reach the liquid surface, reflection occurs due to the difference in medium acoustic impedance. The receiver captures the echo and calculates the propagation time. Combined with the sound velocity correction formula, the liquid level height is obtained.

[0003] If there is a stirring motor or other equipment installed on the tank, the motor will generate vibrations during operation, which will be transmitted to the ultrasonic liquid level meter through the tank structure. The continuous vibration will cause the internal electronic components and mechanical parts of the ultrasonic liquid level meter to be repeatedly impacted and stressed, which may cause the components to loosen, the soldering points to fall off, or the mechanical structure to be damaged. In addition, the fluctuation of the liquid surface in the tank produces irregular reflection surfaces. When ultrasonic waves reflect on these irregular surfaces, false echoes may be generated, causing the liquid level meter to misjudge the liquid level height. Therefore, we propose a non-contact type tank ultrasonic liquid level meter. SUMMARY

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0036] As shown in Figure 1 and Figure 2 , the present application provides a technical solution: a non-contact type tank ultrasonic liquid level meter, comprising:

[0037] The sealed tank 1, the ultrasonic liquid level meter body 2 arranged at the top of the sealed tank 1;

[0038] The damping assembly 3 is arranged at the top of the ultrasonic liquid level meter body 2, and the damping assembly 3 comprises a connecting ring 31 arranged at the top of the ultrasonic liquid level meter body 2, a first sliding rail 32 connected to the connecting ring 31, a fixing ring 33 connected to the side of the first sliding rail 32 away from the connecting ring 31, a first sliding block 36 slidably connected in the first sliding rail 32, a spring 34 fixedly connected between the first sliding block 36 and the inner wall of the first sliding rail 32, a damper 35 arranged in the spring 34, a connecting rod 37 connected to the top of the first sliding block 36, a sleeve ring 38 sleeved on the ultrasonic liquid level meter body 2, the connecting rod 37 being connected to the sleeve ring 38, and the four damping assemblies 3 being arranged around the ultrasonic liquid level meter body 2 respectively;

[0039] The support assembly 4 is arranged on the ultrasonic liquid level meter body 2, and the support assembly 4 comprises a limiting ring 41 arranged on the ultrasonic liquid level meter body 2 and a support rod 42 fixedly connected between the limiting ring 41 and the connecting ring 31;

[0040] Specifically, when the internal stirring assembly of the tank works, the vibration generated is transmitted to the liquid level meter, the connecting rod 37 at the bottom of the liquid level meter drives the first sliding block 36 to move in the first sliding rail 32 to the side away from the liquid level meter, so as to extrude the spring 34 and the damper 35 inside, and then the spring 34 and the damper 35 can offset the impact force generated by part of the vibration to protect the elements inside the liquid level meter.

[0041] Further, as shown in Figure 1 : the side of the ultrasonic liquid level meter body 2 close to the limiting ring 41 is provided with a connecting assembly 8, the connecting assembly 8 comprises a support plate 81, and a bolt 82 is threadedly connected between the support plate 81 and the limiting ring 41, and the connecting assembly 8 is arranged to connect and fix the support assembly 4 and the sealed tank 1;

[0042] The above solutions also have the problem that when external corrosive liquids such as rainwater come into contact with the level gauge, it can damage its internal components, such as... Figure 3 and Figure 4 As shown: The ultrasonic level gauge body 2 is provided with a protective component 5. The protective component 5 includes a protective shell 51, a rotating shaft 52 rotatably connected to the protective shell 51, a cover plate 53 rotatably connected to the rotating shaft 52, an exhaust port 56 on the cover plate 53, a buckle 54 on the cover plate 53, and a retaining seat 55 on the protective shell 51 near the buckle 54. The buckle 54 is engaged in the retaining seat 55, and the cover plate 53 is closed by the rotating shaft 52. Then the buckle 54 is engaged in the retaining seat 55 for limiting and sealing the level gauge dial.

[0043] The above solutions also have the problem that, during the ventilation and moisture-proofing process, a large amount of dust will accumulate on the dustproof net 61 over a long period of time, thus affecting the ventilation effect. Figure 3 and Figure 4 As shown: A dustproof component 6 is provided on the side of the protective shell 51 near the exhaust port 56. The dustproof component 6 includes a dustproof net 61. A second slide rail 62 is provided on the side of the protective shell 51 near the dustproof net 61. A brush plate 63 is slidably connected to the second slide rail 62. The brush plate 63 is slidably moved in the second slide rail 62 by a second slider, thereby cleaning the dust on the dustproof net 61.

[0044] Furthermore, such as Figure 1 As shown: A rubber plate 7 is fixedly connected to the bottom of the sealed tank 1. By setting the rubber plate 7, the vibration generated by the surrounding equipment can be absorbed and transmitted to the tank body.

[0045] The working principle of this utility model is as follows: First, the support component 4 is connected to the support plate 81 by bolts 82. Then, the cover plate 53 is closed by the rotating shaft 52. Then, the buckle 54 is locked in the seat 55 for limiting and sealing the level gauge dial. The vent 56 on the cover plate 53 provides ventilation and moisture protection for the interior. During the moisture protection process, the dustproof net 61 will block external dust from entering the interior. The brush plate 63 slides in the second slide rail 62 through the second slider to clean the dust on the dustproof net 61. When the stirring component inside the tank is working, the vibration generated is transmitted to the level gauge. The connecting rod 37 at the bottom of the level gauge will drive the first slider 36 to move away from the level gauge in the first slide rail 32, thereby squeezing the spring 34 and the internal damper 35. Then, the spring 34 and the damper 35 will offset part of the impact force generated by the vibration and protect the internal components of the level gauge. The rubber plate 7 can absorb the vibration generated by the surrounding equipment and transmit it to the tank.

[0046] The above merely describes preferred embodiments of the present application and is not intended to limit the present application in any form, although the present application has been disclosed as above with preferred embodiments, however, it is not intended to limit the present application, any person skilled in the art without departing from the technical scheme of the present application can make some changes or modifications to the above-mentioned technical content for equivalent embodiments, the implementation schemes in the above-mentioned embodiments can be further combined or replaced, as long as it does not deviate from the technical scheme of the present application, any simple modification, equivalent change and modification made to the above-mentioned embodiments according to the technical essence of the present application still belongs to the scope of the present application.
