Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in the figure, the present embodiment includes an oil tank 20, a magnetic float working cylinder 1, a magnetic turning plate 2 and a magnetic float 3, the magnetic turning plate 2 is located outside the magnetic float working cylinder 1, the magnetic float 3 is located in the magnetic float working cylinder 1, and the magnetic sheet on the magnetic float 3 and the magnetic turning plate 2 is driven to turn over for 180 degrees through magnetic coupling to realize liquid level indication. The above is the structure existing in the prior art, and is not described in detail herein.

The innovation points of the embodiment are as follows: the difference of board level gauge is turned over with current magnetism, the utility model provides a magnetic float working barrel 1 need not constitute the linker with oil tank 20, so the liquid is not banked up in the magnetic float working barrel 1 to accomplish to avoid freezing stifled condition and taken place. Although the present embodiment does not use the communicating vessel principle of the magnetic flap level gauge, the present embodiment still uses the magnetic coupling principle of the magnetic flap level gauge, and the magnetic sheet is driven by the up-and-down floating of the magnetic float 3 to turn over 180 degrees, so as to realize the level indication. The magnetic float descending balance weight 5 is connected above the magnetic float 3, the magnetic float pull wire 7 is connected above the magnetic float descending balance weight 5, and the magnetic float descending balance weight 5 has the function that the magnetic float descending balance weight 5 drives the magnetic float 3 to descend after the magnetic float pull wire is loosened 7. A guide wheel A8, a driven guide roller 11, a driving guide roller 12, a guide wheel B14 and a support plate 10 are arranged above the outer part of the oil tank 20, wherein a guide wheel A adjusting frame 9 is installed on the support plate 10, and a guide wheel 8 is installed on the guide wheel A adjusting frame 9; the driving guide roller 12 drives the driven guide roller 11 to synchronously rotate reversely through a gear; the magnetic float pull wire 7 is fixed on the driven guide roller 11 after bypassing the guide wheel A8, the magnetic float 3 is pulled to rise when the driven guide roller 11 rotates clockwise, and on the contrary, the magnetic float 3 falls when the driven guide roller 11 rotates counterclockwise. The oil tank 20 is internally provided with a liquid level floater 16 floating above the liquid level, a liquid level floater pull wire 15 is connected above the liquid level floater 16, the liquid level floater pull wire 15 is fixed on the active guide roller 12 after bypassing the guide wheel B14, the active guide roller 12 is also wound with a balance pull wire 18, and the lower end of the balance pull wire 18 is connected with a balance weight 19, so that the balance weight 19 descends when the liquid level floater 16 ascends, and vice versa.
