Technical Field

[0001] The utility model relates to the field of liquid level transmitters, and specifically relates to a protection structure for a liquid level transmitter. Background Technique

[0002] The liquid level transmitter is an extension and development of the pressure transmitter technology. According to the principle that the pressure generated by liquids with different specific gravities at different heights is linearly related, it realizes the accurate measurement and transmission of the volume, liquid height, and weight of water, oil, and pastes. Currently, the liquid level transmitter often detects the liquid level by putting the sensor probe connected to the cable into the water. However, the cable is prone to swaying left and right with the flow of water, thus affecting the accuracy of the sensor probe in detecting the liquid level. Therefore, a protection structure for a liquid level transmitter is needed.

[0003] For the existing liquid level transmitters, when in use, it is inconvenient to protect the sensor probe and it is also inconvenient to fix the liquid level transmitter at the required position. Therefore, a protection structure for a liquid level transmitter is urgently needed. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a protection structure for a liquid level transmitter to solve the problems that the existing liquid level transmitters are inconvenient to protect the sensor probe and inconvenient to fix.

A cable is fixedly connected to the bottom of the liquid level transmitter housing. One end of the cable is fixedly connected to a sensor probe. A sleeve is fixedly connected to the bottom of the liquid level transmitter housing. A threaded column is movably connected inside the sleeve. A connecting block is fixedly connected to the bottom of the threaded column. A guide rod is fixedly connected to the bottom of the connecting block. A protective sleeve ring is fixedly connected to the outer wall of the guide rod.

A bolt is movably connected inside the support plate. One end of the bolt is movably connected to a clamping plate. A movable plate is fixedly connected to one side of the clamping plate.

[0007] Preferably, the sleeve is of a slotted design, and the threaded column is threadedly connected to the sleeve.
