Description

Technical Field

[0001] The utility model provides an ultrasonic liquid level meter, belongs to the technical field of ultrasonic liquid level meter equipment, and particularly relates to a detachable portable ultrasonic liquid level meter. Background Art

[0002] Ultrasonic level meter is an instrument that uses ultrasonic signals to measure the liquid level. Its working principle is that the ultrasonic transmitter emits ultrasonic pulses to the liquid surface. After the ultrasonic wave is reflected on the liquid surface, it is received by the receiver on the same device. The liquid level is determined by calculating the product of the ultrasonic round trip time and the known speed of sound. This technology is widely used in various liquid storage and processing facilities, such as water treatment plants, chemical plants, food processing plants and petrochemical equipment. The common detection methods of existing ultrasonic level meters can be divided into two methods: acoustic wave refraction on the liquid and acoustic wave refraction in the liquid to detect the liquid level.

[0003] When the sound waves in the liquid are refracted, the sound wave signals are emitted from the bottom of the liquid storage tank. After touching the liquid level position, the sound wave signals are returned to the converter. The advantage of this method is that it can intuitively display the real-time changes of the liquid level position. However, when the liquid level meter needs to be replaced or repaired, the liquid level meter cannot be broken and disassembled. The internal liquid needs to be emptied before replacement. This method has certain limitations and is inconvenient to use. Utility Model Content

[0024] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific implementation methods and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] like Figure 1 and Figure 2 As shown, a detachable portable ultrasonic level meter comprises a liquid storage tank 1, a liquid level meter body 2 is installed at the bottom of the liquid storage tank 1 through an adjusting groove 11, an end of the liquid level meter body 2 close to the liquid storage tank 1 is sleeved with an adjusting frame 21 placed inside the adjusting groove 11, a limiting member 23 is connected between the adjusting frame 21 and the spring 22, a limiting groove 24 penetrating the limiting member 23 is provided inside, the springs 22 are evenly distributed along the outer circle of the limiting groove 24 and are fixedly connected to the limiting member 23, a side of the adjusting frame 21 close to the liquid level meter body 2 is connected to a plurality of evenly distributed springs 22, and the other side of the adjusting frame 21 is provided with a rotating plate 12 corresponding to itself.

[0027] In the present embodiment, a liquid level gauge body 2 is arranged to be installed at the bottom end of the liquid storage tank 1 by means of an adjusting groove 11, and cooperates with a spring 22 and an adjusting frame 21, so that the liquid storage tank 1 can be sealed when the liquid level gauge body 2 is not installed. At the same time, the adjusting frame 21 drives the rotating plate 12 to rotate, and the rotating plate 12 is closed and opened as the liquid level gauge body 2 is disassembled and installed, which is convenient for use. The opening of the rotating plate 12 can avoid affecting the sound wave signal of the liquid level gauge body.

[0028] like Figure 3 , 4As shown in Figure 5, a sealing nut 25 sleeved on the outside of the liquid level meter body 2 is provided inside the limit groove 24, and a sliding groove 26 with a height greater than the length of the spring 22 in the normal state is provided on the outside of the sealing nut 25. The spring 22 is placed inside the sliding groove 26. The rotating plate 12 is a plurality of compactly distributed rubber plates. The overall shape of the rotating plate 12 is a circle with a diameter smaller than the adjusting groove 11. An adjusting column 13 is connected to the side of the rotating plate 12 close to the adjusting frame 21. The adjusting frame 21 is provided with an arc-shaped adjusting slide groove 27 corresponding to the adjusting column 13. The adjusting groove 11 is provided with a slide rail 14 for limiting the movement of the rotating plate 12.

[0029] In this embodiment, after the sealing nut 25 is inserted into the limit groove 24 in the limit member 23, the liquid level gauge body 2 is rotated, thereby driving the limit member 23 to rotate, and then the adjusting frame 21 is rotated. The adjusting frame 21 uses the adjusting groove 27 on itself to drive the rotating plate 12 to rotate through the adjusting column 13 when rotating. The rotating plate 12 is restricted by the slide rail 14, and the rotation direction is along the slide rail 14 and the adjusting groove 27, thereby realizing opening and closing. It should be noted that the sealing nut 25 and the limit member 23 are both made of sealing materials, and a sealing material shell is provided on the outer wall of the liquid level gauge body 2. After being inserted into the bottom end of the liquid storage tank 1, it can assist in sealing and can also be installed with the help of friction.

[0030] When in use, the level meter body 2 is installed at the bottom of the liquid storage tank 1. Through the adjustment groove 11, the level meter body can be firmly installed at the bottom of the liquid storage tank to ensure that it is in the correct position so as to accurately measure the liquid level; the adjustment frame 21 is sleeved on the outside of one end of the level meter body 2 and is connected to the limiter 23 through the spring 22. The limiter groove 24 allows the level meter body to move appropriately during installation or removal, and is supported by the spring 22 to keep it stable; during the installation or removal of the level meter body 2, the level meter body is rotated to drive the limiter 23 and the adjustment frame 21 to rotate. The adjustment column 13 on the adjustment frame 21 cooperates with the adjustment slide 27 to drive the rotating plate 12 to open and close. The rotating plate 12 is composed of a plurality of rubber plates, and the overall shape is circular, and the diameter is smaller than the adjustment groove 11, so as to facilitate sealing and operation; the sealing nut 25 is inserted into the limiter groove 24 in the limiter 23, and together with the level meter body 2, assists in achieving sealing. The outer wall of the level meter body 2 is provided with a sealing material shell, which not only provides a sealing effect, but also facilitates the stable installation in the liquid storage tank through friction; after the installation is completed, the level meter can be used to measure the liquid level. The ultrasonic transmitter transmits ultrasonic waves into the liquid, and the reflected waves are captured by the receiver. The distance between the liquid surface and the sensor is calculated based on the time difference of ultrasonic propagation.

[0031] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
