Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] see figure 1 , a spirit level with an indicating tube heating mechanism, including a base 5, an indicating tube heating structure 6, a temperature sensor 51 and a control unit (not shown in the figure).

[0015] An indicating tube 53 is arranged inside the base 5 . The indicating tube 53 is a transparent tube such as glass, acrylic and the like. An observation window 54 is provided on the upper surface of the base 5 directly above the indicating tube 53 . The indicating tube 53 is provided with air bubbles 55 and filled with liquid. The temperature sensor 51 is located in the indicating tube 53 .

[0016] The indicating tube heating structure 6 includes a thermally conductive iron shell 61 , a metal scraper 62 and a driving mechanism 63 . The outer surface of the iron shell 61 is a cylindrical surface. The iron shell 61 is sheathed on the o...

Abstract

The invention relates to a level gauge, in particular to a level gauge provided with an indicator tube heating mechanism. The level gauge comprises a base, an indicator tube heating structure, a temperature sensor for detecting the temperature of an indicator tube and a control unit, wherein the base is internally provided with the indicator tube; the indicator tube is filled with bubbles and liquid; the indicator tube heating structure comprises an iron shell with heat conductivity and wrapped outside the indicator tube, a metal scraping fork slidably sleeved outside the iron shell and a driving mechanism for driving the metal scraping fork to reciprocate; the iron shell is provided with an avoiding groove for observing the position of the bubbles; and the control unit controls the driving mechanism to drive the metal scraping fork to move when the temperature of the indicator tube is detected by the temperature sensor to be lower than a set value. The level gauge provided by the invention has the advantages of being capable of heating the indicator tube when the ambient temperature is low, and solves the problem that the existing level gauge cannot heat the indicator tube to resist errors caused by temperature reduction.

Description

technical field [0001] The invention relates to a level, in particular to a level equipped with a heating mechanism for an indicating tube. Background technique [0002] A spirit level is an instrument used to measure whether an object is level. In the patent document whose publication number is CN101970986A promptly discloses a kind of existing spirit level. The spirit level includes a base, and an indicating tube is arranged in the base, and the indicating tube is provided with air bubbles and filled with liquid. When in use, place the base on the object to be measured, and judge whether the object is level by observing the position of the air bubbles. The accuracy of the level meter is affected by the diameter of the indicating tube. The larger the diameter, the higher the accuracy. The higher the accuracy, the smaller the error, that is, the better the accuracy of the measured data. However, the level meter is suitable for the environment where the temperature is lowe...
