Description

Technical Field

[0001] The utility model relates to the technical field of coupling agent filling, in particular to a liquid level sensing device for coupling agent filling. Background Art

[0002] The liquid level sensing device for coupling agent filling is a device specially used to monitor and control the liquid level changes during the coupling agent filling process. The liquid level sensing device for coupling agent filling is usually composed of a liquid level sensor, a signal processing unit, a display and control unit, and an alarm and interlocking device. When the sensor is immersed in a certain depth in the liquid to be measured, the pressure on the liquid surface of the sensor is proportional to the density of the liquid, the acceleration of gravity, and the depth of the sensor immersed in the liquid. The pressure of the liquid is introduced into the positive pressure chamber of the sensor through the gas-conducting stainless steel, and the atmospheric pressure on the liquid surface is connected to the negative pressure chamber of the sensor to offset the atmospheric pressure on the back of the sensor. The pressure measured by the sensor is the static pressure generated by the liquid. By measuring this pressure and undergoing a series of signal processing, the liquid level depth can be obtained.

[0003] For example, the Chinese patent "A liquid level sensing device for acid addition" with announcement number CN210135970U includes a funnel, which includes a conical bucket and a tube body connected to the lower port of the bucket; a row of wire tubes is fixed on the inner side wall of the conical bucket, a fixing block is provided at the open end of the conical bucket, and a mounting seat is installed on the fixing block in cooperation, a plurality of mounting blocks are provided on one side of the mounting seat, a mounting hole is opened on the mounting block, and a light-emitting diode is installed in cooperation with the mounting hole; a fixing plate is provided on the inner wall of the tube body, a first through hole for inserting a wire is provided on the fixing plate, and a winding post is fixed on the fixing plate; a power supply is provided on the mounting seat, any one terminal of the light-emitting diode is electrically connected to the positive / negative pole of the power supply, the positive / negative pole of the power supply is electrically connected to a wire a, the wire a extends into the tube body and is wound around the winding post, the end of the wire a is electrically connected to a conductive tube a, and the conductive tube a is located at the bottom end of the winding post.

[0004] Although the above-mentioned prior art can realize the filling detection of liquid, in actual use, on the one hand, the liquid level detection is not sensitive enough when the coupling liquid is filled. Usually, the liquid level detection uses electrode detection. When the liquid contacts the electrode sheet, the electrode sheet is energized and sends a signal to stop filling, resulting in a certain time interval between the liquid level reaching and the signal being sent, thereby reducing the sensitivity of the liquid level detection. On the other hand, the filling makes the bottle body easy to shake. When the coupling liquid is filled, the coupling liquid impacts the bottom of the bottle body, causing the bottle body to shake, thereby affecting the filling of the coupling liquid. Therefore, it does not meet the existing needs. In this regard, we propose a liquid level sensing device for coupling agent filling. Utility Model Content

[0013] Preferably, a bottle body is arranged inside the positioning hole, and the bottle body is slidably matched with the positioning hole.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model can detect the liquid level of coupling liquid inside bottles of different sizes through ultrasonic liquid level sensors and hydraulic telescopic devices. Before the coupling liquid is filled, the bottle is placed in the positioning hole. At this time, the hydraulic telescopic device is turned on to extend the telescopic end of the hydraulic telescopic device. The telescopic end of the hydraulic telescopic device drives the moving plate and the filling tube to move downward together until the filling tube and the ultrasonic liquid level sensor enter the interior of the bottle. The position of the filling tube is adjusted according to the bottles of different heights. At this time, when filling, the height of the liquid surface is detected by the ultrasonic liquid level sensor to avoid the coupling liquid from overflowing during filling, and the sensing device is adapted to bottles of different sizes.

[0016] 2. The utility model can fix the bottle body during filling by means of the spring and the rubber disc. When filling, the bottle body has been placed in the positioning hole. At this time, the lower end of the filling tube moves downward until the lower end of the filling tube moves into the interior of the bottle body. At this time, the filling tube continues to move downward until the lower end of the rubber disc contacts and squeezes the opening of the bottle body. At the same time, the spring is in a stretched state. At this time, the squeezing force of the rubber disc on the bottle body gradually increases until the filling tube moves to a suitable position. At this time, the bottle body is fixed by squeezing the rubber disc. At the same time, the rubber disc can reduce the dust in the working environment from falling into the interior of the bottle body, thereby ensuring the purity of the coupling liquid.

[0017] 3. The utility model is provided with a positioning hole, so that the bottle body can be placed directly below the filling tube. When the coupling liquid is filled, the lower end of the bottle body is placed in the positioning hole, and the positioning hole is located directly below the filling tube. The bottle body can be quickly positioned and placed through the positioning hole, which simplifies the positioning of the bottle body. At the same time, the bottom of the bottle body is fixed through the positioning hole to avoid the position displacement of the bottle body when the coupling liquid is filled.
