Description
Technical Field
[0001] The utility model relates to the technical field of magnetostrictive liquid level gauges, in particular to a magnetostrictive liquid level gauge with a protective structure. Background Art
[0002] The magnetostrictive liquid level sensor is designed based on the magnetostrictive principle. It consists of a sensitive waveguide wire, a waveguide tube, a movable magnet, and electronic components that transmit electrical pulse signals and receive return signals. When the electrical pulse generated by the pulse microwave generator in the electronic probe is transmitted along the waveguide wire in the steel pipe, the electrical pulse is accompanied by a circular magnetic field perpendicular to the waveguide wire and transmitted along the waveguide wire at the speed of light. When the pulsed circular magnetic field meets the magnetic field of the magnetic float, the magnetic field vectors of the two are superimposed to form a spiral magnetic field, which generates instantaneous torque and forms a mechanical torque wave on the waveguide wire. This torque wave returns to the electronic probe at the speed of light, causing pulse induction at both ends of the coil. By measuring the time difference between the generated pulse and the induced pulse generated by the return of the torque wave, the height of the measured liquid level can be accurately calculated. At the same time, the temperature sensor is placed in the measuring rod to continuously measure the medium temperature.
[0003] After the existing magnetostrictive liquid level gauge has completed measurement, the liquid attached to the measuring rod and the float will drip when it is drawn out from the tank, causing the operator and the surface of the tank mouth to be stained with liquid, which is likely to cause safety hazards to the operator and corrosion of the tank mouth. At the same time, the dripping caused by multiple measurements will also cause waste of liquid in the tank. Therefore, a magnetostrictive liquid level gauge with a protective structure is proposed.

[0013] The working principle and beneficial effects of the utility model are:
[0014] 1. In the utility model, by providing a material receiving mechanism, before the mounting flange is butted against the tank mouth flange, the connecting rod can be rotated more than degrees, so that the mounting flange will not be obstructed during the installation process. When the measuring rod is pulled out of the tank to be located directly above the tank mouth, the connecting rod is reset, so that the material receiving plate is rotated to be located below the measuring rod.

When the receiving plate rotates, the rotating shaft column is driven to rotate synchronously through the rotating shaft. When the receiving plate rotates ninety degrees, the latch is aligned with the latch hole, so that the spring is no longer pushed by external force to insert the latch into the latch hole, thereby fixing the receiving plate and the connecting block, thereby realizing the function of folding the receiving plate, thereby improving the overall practicality of the device.
[0016] 3. In the utility model, a buffer mechanism is provided. When the measuring rod is inserted into the liquid in the tank, the liquid can slowly flow into the inner side of the buffer casing through a plurality of buffer holes, thereby dispersing the liquid. This can buffer the liquid in the tank and prevent the liquid in the tank from directly impacting the float. At the same time, the buffer casing can prevent the liquid in the tank from directly impacting the float in the first place, thereby achieving a protective effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In this embodiment: before the mounting flange 2 is docked with the tank mouth flange, the connecting rod 503 can be rotated more than 90 degrees so that the mounting flange 2 will not be obstructed during the installation process. After the measuring rod 1 is pulled out of the tank to be directly above the tank mouth, the connecting rod 503 is reset so that the receiving plate 515 is rotated to be located below the measuring rod 1. In this way, the receiving plate 515 can stably receive the liquid dripping from the measuring rod 1 to prevent the received liquid from splashing when encountering external force, thereby achieving the effect of protecting the operator and the tank mouth surface.
