Description

Technical Field

[0001] The present application relates to the technical field of nonferrous and metallurgical equipment, and in particular to a float level gauge device. Background Art

[0002] In the rolling process of materials, the production of precision strips requires rolling oil for cooling and lubrication. The rolling oil will also carry away a large amount of waste slag, resulting in the need for repeated filtration of the rolling oil. Therefore, in the oil tank, the rolling oil level needs to be monitored in real time. Since traditional level gauges are not oil-resistant, they are prone to corrosion and damage, resulting in the failure of the level gauge and the inability to accurately monitor the liquid level, affecting production efficiency. Therefore, there is an urgent need for a level gauge device that can monitor the liquid level in the oil tank in real time and has a simple structure and is corrosion-resistant to improve production efficiency. Utility Model Content

[0003] In order to accurately monitor the oil tank liquid level in real time, the structure is simple and the efficiency is improved.

[0004] The present application provides a float level gauge device that adopts the following technical solution:

[0005] A float level gauge device includes a draw-wire sensor assembly, including an outer cover protection component and a draw-wire sensor, wherein the draw-wire sensor is detachably arranged in the outer cover protection component to isolate the draw-wire sensor from direct contact with external rolling oil;

[0006] It also includes a float, which is arranged outside the outer cover protection component and is floatingly connected to the pull rope sensor through a connecting piece, and the connecting piece is extended and contracted as the float floats.

[0007] Preferably, the outer cover protective component includes a flange plate, a cover shell and a bracket, the cover shell is hollow and has an opening at the bottom, the flange plate is detachably arranged at the bottom opening of the cover shell, the bracket is detachably arranged on a side of the flange plate facing the inner cavity of the cover shell, and the stretching sensor is arranged on the bracket.

[0008] Furthermore, the flange plate is connected to the cover shell via a plurality of hexagon socket head bolts.

[0009] Preferably, the connecting member comprises a stainless steel draw cord.

[0010] Preferably, the bracket is connected to the flange plate via a plurality of hexagon socket head bolts, and the bracket is connected to the rope sensor via at least one hexagon socket head bolt.

[0011] Preferably, a certain floating gap is reserved between the outer wall of the floating ball and the inner wall of the oil tank to be tested, and the floating gap is between 3-5 cm.

[0012] Compared with the prior art, the float liquid level gauge device of the utility model has the following beneficial technical effects:

[0013] 1. When the utility model is used, a stainless steel pull rope is used as a connector to connect the float and the pull rope sensor. When movement occurs, the connector stretches and contracts, and the internal spring of the pull rope sensor ensures that the tension of the connector remains unchanged. As the pull rope stretches or contracts, the precision rotation sensor in the pull rope sensor is driven to rotate, and an electrical signal proportional to the distance the pull rope moves is output. The displacement, direction or speed of the moving object can be obtained by measuring the output signal, and the tank liquid level height can be accurately monitored in real time. The structure is simple and the efficiency is improved.

[0014] 2. When the utility model is used, the outer cover protection component can avoid the possibility of corrosion and damage caused by direct contact between the pull rope sensor and the rolling oil as much as possible. BRIEF DESCRIPTION OF THE DRAWINGS
