Description

Technical Field

[0001] The utility model belongs to the technical field related to liquid level sensors, and particularly relates to an integrated liquid level and temperature sensor. Background Technique

[0002] A liquid level sensor is a device used to monitor and control the liquid level, which is widely used in industrial automation and intelligent control systems. Liquid level sensors have a wide range of applications in multiple industries, such as petrochemical, water supply systems, pharmaceutical production, environmental monitoring, etc. They can be used to monitor and control the liquid level of liquids, provide accurate data, and be integrated into larger fluid control systems. In addition, liquid level sensors can also be used for various functions such as leakage detection, liquid level identification, and discrimination of gas / liquid two-phase interfaces or oil / water interfaces. However, there are still the following drawbacks in its actual use:

[0003] When the liquid level sensor is working, it can only measure the liquid level of the liquid in the container. During the operation, the temperature of the liquid in the container is also an important data. The liquid level sensor can only measure the liquid level and is not very suitable for measuring the liquid temperature;

[0004] When the liquid level sensor is working, it is directly placed into the container and then installed accordingly. During the working process of the liquid level sensor, if the liquid temperature in the container is too low, such as after solidification, it will cause the liquid level sensor to fail to work and affect the operation of the sensor. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an integrated liquid level and temperature sensor. By setting a liquid level probe, a connecting rod, a heating sleeve, and a second connecting block, the problems that the liquid level sensor is not very suitable for measuring the liquid temperature during operation and the liquid in the container will solidify at low temperature, affecting the operation of the sensor, are solved.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is an integrated liquid level and temperature sensor, including a liquid level probe, a connecting rod, a heating sleeve, and a second connecting block. A temperature sensor is fixed at the bottom end of the liquid level probe. A connecting rod is arranged on one side of the liquid level probe. A heating sleeve is sleeved on the periphery of the connecting rod. A floating block is fixed at the top end of the heating sleeve. A second connecting block is fixed at the lower part of the periphery of the temperature sensor. A thermal switch is fixed at the top of the second connecting block. During operation, the liquid level in the container is detected by the liquid level probe. The heating sleeve is sleeved on its periphery through the connecting rod. The liquid in the container is heated by the heating sleeve to prevent the liquid temperature in the container from being too low. The thermal switch is fixed on it through the second connecting block. When the liquid temperature in the container drops to an extremely low level, the heating sleeve is turned on.

[0008] Further, a mounting seat is fixed at the top end of the liquid level probe, and a liquid level sensor body is fixed at the top end of the mounting seat. The liquid level probe is connected to the liquid level sensor body through the mounting seat, and signals are transmitted to the display and processing device through the liquid level sensor.

[0009] Further, a fixing block is fixed at the top end of the connecting rod, and the fixing block is fixed on the periphery of the mounting seat. The connecting rod is connected to the mounting seat through the fixing block.

[0010] Further, a first connecting block is fixed at the bottom end of the connecting rod, and the first connecting block is fixed at the lower part of the periphery of the temperature sensor. The first connecting block and the second connecting block are symmetrically arranged on the periphery of the temperature sensor. The connecting rod is connected to the temperature sensor through the first connecting block.

[0011] Further, a plurality of heat conducting sheets are fixed on the periphery of the heating sleeve, and the distance between adjacent heat conducting sheets is equal. An activity hole is vertically and penetratingly formed in the floating block, and the connecting rod is penetratingly and movably connected in the activity hole. When the heating sleeve works, heat is transferred to the liquid in the container through the heat conducting sheets.

[0012] Further, a sealing sleeve is fixed on the surface of the thermal switch, and the bottom end of the sealing sleeve is fixed at the top end of the second connecting block. The thermal switch is enclosed at the top of the second connecting block through the sealing sleeve.

[0013] The utility model has the following beneficial effects:

[0014] By arranging the liquid level probe, the utility model solves the problem that the applicability of the liquid level sensor for measuring the liquid temperature during operation is not good enough. When the liquid level probe works, it is inserted into the container, then the mounting bolt is inserted into the liquid level sensor body, and then screwed into the mounting structure in the container. The liquid level of the liquid in the container is detected by the liquid level probe, and at the same time, the liquid temperature in the container is detected by the temperature sensor, so that the applicability of the liquid level sensor for measuring the liquid temperature during operation is better.

[0015] The utility model solves the problem that the liquid in the container will solidify at low temperature during the operation of the liquid level sensor, affecting the operation of the sensor, by setting a liquid level probe, a connecting rod, a heating sleeve and a second connecting block. After the liquid level probe is installed, the sealing sleeve and the second connecting block are submerged in the liquid in the container. When the temperature of the liquid drops, the thermal switch turns on the heating sleeve. After the heating sleeve is turned on, it generates heat, and the heat is transferred to the liquid in the container through the heat conducting sheet. The movable hole on the floating block is movably connected to the periphery of the connecting rod to limit the position, and the floating block generates buoyancy in the liquid in the container, so that the heating sleeve always floats below the liquid level of the liquid in the container. When working, when the temperature of the liquid in the container is too low and solidifies during the operation of the liquid level sensor, heat can be supplemented to prevent the liquid from solidifying and ensure the normal operation of the sensor.
