Description

Technical Field

[0001] The utility model relates to the technical field of liquid level gauges, and particularly relates to a novel ultrasonic liquid level gauge. Background Art

[0002] In measurement, an ultrasonic pulse is emitted by a sensor (transducer). The sound wave is reflected by the liquid surface and then received by the same sensor. It is converted into an electrical signal through a piezoelectric crystal, and the distance from the sensor to the measured liquid surface is calculated by the time between the emission and reception of the sound wave. Due to the non-contact measurement, the measured medium is almost not restricted, and it can be widely used for the measurement of the heights of various liquids and solid materials.

[0003] The existing ultrasonic liquid level gauges have the following defects:

[0004] 1. When the existing ultrasonic liquid level gauge is in use, the ultrasonic wave is not fixed stably, resulting in that the ultrasonic liquid level gauge cannot directly irradiate the water surface. Further, there will be errors when the ultrasonic liquid level gauge measures the water level, thus affecting the use by the staff.

[0005] 2. When the existing ultrasonic liquid level gauge is in use, the ultrasonic liquid level gauge has no protection function. Therefore, the instrument of the ultrasonic liquid level gauge will be damaged by external factors, and the surface of the ultrasonic liquid level gauge will also be corroded by the liquid in the container, thus affecting the service life of the device body.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 - 3 , the embodiments of the present utility model provide a technical solution: a new type of ultrasonic liquid level gauge, including a device body 1. The device body 1 includes a liquid level gauge 2, an adjustment device 3 and a protective cover 8. The adjustment device 3 is located at the bottom of the device body 1. The adjustment device 3 includes a first fixator 20 and a second fixator 21. The liquid level gauge 2 is fixed between the first fixator 20 and the second fixator 21. The liquid level gauge 2 includes an ultrasonic device 4, an outer shell 9, a flange 5, a connecting block 6 and a liquid crystal meter 7. The ultrasonic device 4 is fixed at the bottom of the outer shell 9. The liquid crystal meter 7 is installed inside the outer shell 9. The flange 5 is installed on the top of the outer shell 9. The connecting block 6 is installed on the outer side of the top of the flange 5. The protective cover 8 is fixed on the top of the connecting block 6;

[0025] Both the first fixture 20 and the second fixture 21 include a fixing plate 10, a rotating shaft 11, and a fixing frame 12. One end of the rotating shaft 11 is installed inside the fixing plate 10, the top of the fixing frame 12 is fixed to the other end of the rotating shaft 11, the bottom of the fixing frame 12 is bevel-shaped, a first fixing block 13 is installed in the middle of the inner side of the fixing frame 12, and a second fixing block 14 is installed at the bottom end of the inner side of the fixing frame 12. The first fixture 20 and the second fixture 21 are installed symmetrically. The adjusting device 3 can automatically adjust the angle of the liquid level gauge 2, so that the bottom of the liquid level gauge 2 is always flat against the water surface, further improving the accuracy of the liquid level gauge 2 in measuring the water surface.

[0026] A set of screw holes 15 distributed symmetrically are formed at the top of the fixing plate 10, and a rubber pad 16 is pasted on the bottom of the fixing plate 10. The fixing plate 10 can fix the fixing frame 12. When the staff fixes the fixing plate 10, the staff inserts a fixing screw into the screw hole 15 on the fixing plate 10 to fix the fixing plate 10, and the rubber pad 16 at the bottom of the fixing plate 10 can fit the installation point, thereby improving the fitting degree of the fixing plate 10 to the installation point and further improving the stability of the installation of the fixing plate 10.

[0027] The protective cover 8 is semicircular, a water condensation film 17 is pasted on the surface of the protective cover 8, the water condensation film 17 is transparent, and a number of groups of connecting threads 18 are provided on the inner side of the bottom end of the protective cover 8. The protective cover 8 can protect the liquid crystal meter 7 in the liquid level gauge 2 from being damaged by collision, and the protective cover 8 can prevent the influence of rainwater on it, so as to achieve the waterproof effect, and the water condensation film 17 on the surface of the protective cover 8 can prevent rainwater from staying in the protective cover 8 for a long time and affecting the staff's observation of the liquid crystal meter 7.

[0028] A number of groups of connecting threads 18 are provided on the surface of the connecting block 6 at equal intervals up and down. The connecting threads 18 on the surface of the connecting block 6 are for the convenience of connecting the protective cover 8. Thus, the staff only needs to cooperate the connecting threads 18 at the bottom inside of the protective cover 8 with the connecting threads 18 on the surface of the connecting block 6 to complete the installation of the protective cover 8.

[0029] Anticorrosive paint 19 is sprayed on the surfaces of both the liquid level gauge 2 and the adjusting device 3. The anticorrosive paint 19 is acrylic anticorrosive paint. The anticorrosive paint 19 sprayed on the surfaces of the liquid level gauge 2 and the adjusting device 3 can effectively protect the liquid level gauge 2 and the adjusting device 3, preventing the liquid in the container from corroding the surfaces of the liquid level gauge 2 and the adjusting device 3 and thus affecting the service life of the liquid level gauge 2 and the adjusting device 3.

[0030] Working principle: During operation, the staff installs the adjustment device 3. The staff installs the first fixator 20 inside the adjustment device 2 at the left end and the second fixator 21 at the right end. When installing the first fixator 20 and the second fixator 21, the staff inserts fixing screws into the screw holes 15 on the fixing plate 10 to fix the fixing plate 10. The rubber pad 16 at the bottom of the fixing plate 10 can fit the installation point, thereby improving the fitting degree of the fixing plate 10 to the installation point and further enhancing the stability of the installation of the fixing plate 10. The staff places the liquid level gauge 2 between the first fixator 20 and the second fixator 21. The first fixator 20 and the second fixator 21 are provided with a fixing frame 12. The first fixing block 13 in the middle of the fixing frame 12 and the second fixing block 14 at the bottom can clamp the upper and lower ends of the liquid gauge 2, thereby fixing the liquid level gauge 2. When the adjustment device 3 adjusts the direction of the liquid level gauge 2, the rotating shafts 11 in the first fixator 20 and the second fixator 21 rotate by changing the angle, so that the fixing frame 12 will be perpendicular downward. Consequently, the liquid level gauge 2 between the first fixator 20 and the second fixator 21 will also change the angle, ensuring that the bottom of the liquid level gauge 2 always faces downward, which is convenient for the liquid level gauge 2 to monitor the water surface and further improves the accuracy of the liquid level gauge monitoring. The protective cover 8 installed at the top of the liquid level gauge 2 can protect the liquid crystal instrument 7 inside the liquid level gauge 2, preventing the liquid crystal instrument 7 from being damaged by collision. The protective cover 8 can also prevent the influence of rainwater, achieving a waterproof effect. The water condensation film 17 on the surface of the protective cover 8 can prevent rainwater from staying inside the protective cover 8 for a long time, affecting the staff's observation of the liquid crystal instrument 7. The anti-corrosion paint 19 sprayed on the surfaces of the liquid level gauge 2 and the adjustment device 3 can effectively protect the liquid level gauge 2 and the adjustment device 3, preventing the liquid in the container from corroding the surfaces of the liquid level gauge 2 and the adjustment device 3 and thus affecting the service life of the liquid level gauge 2 and the adjustment device 3.
