Description

Technical Field

[0001] The utility model relates to the field of scales, in particular to a scale device suitable for bellows of combined electrical appliances. Background Art

[0002] At present, the power system has penetrated all walks of life in society. For the development of society, it can be said that it is impossible to move forward without electricity. As a particularly important part of the power system, various dimensional errors caused by civil construction, equipment manufacturing, installation, etc. must be considered during the installation and operation of combined electrical appliances. Especially during operation, due to factors such as thermal expansion and contraction caused by temperature changes and uneven settlement of the foundation, it will lead to deformations and stresses exceeding the allowable values, endangering the safe operation of the equipment. Therefore, when combined electrical appliances are applied in actual projects, it is particularly important to properly install bellows to compensate for errors caused by thermal expansion and contraction during equipment manufacturing, installation, and operation. The bellows of combined electrical appliances are divided into installation-type bellows and temperature-compensating bellows. The installation-type bellows are mainly used for installation adjustment and compensation of relative displacement between foundations. The temperature-compensating bellows not only have the functions of the installation-type bellows but also can absorb small displacements of the equipment caused by thermal expansion and contraction or other external forces. In order to observe the change in the expansion and contraction amount of the temperature-compensating bellows in real time, a scale needs to be installed on the temperature-compensating bellows.

[0003] In the prior art, the scale for measuring the bellows needs to be installed and fixed by means of the body bolts, which has potential safety hazards and is not easy to implement. Content of the Utility Model

[0004] The purpose of the utility model is to address the problem in the background art that the scale needs to be installed and fixed by means of the body bolts, which has potential safety hazards and is not easy to implement, and to propose a scale device suitable for bellows of combined electrical appliances.

[0005] The technical solution of the utility model: A scale device suitable for bellows of combined electrical appliances includes two bellows flanges on both sides of the bellows; it also includes:

[0006] Fixing plates, detachably arranged on the bellows flanges, and two fixing plates are correspondingly arranged with the bellows flanges;

[0007] A left bending plate, arranged on one fixing plate along the length direction of the bellows;

[0008] A right bending plate, arranged on the other fixing plate along the length direction of the bellows, and the left bending plate and the right bending plate are located between the two fixing plates;

[0009] A scale, arranged on the right bending plate, and a strip-shaped groove is opened on the scale along the length direction of the bellows;

[0010] And a pointer, which is arranged on the left bending plate, passes through the strip-shaped groove and points to the scale line on the scale.

[0011] Preferably, a strip-shaped groove for inserting the bellows flange is arranged on the fixing plate, and the fixing plate and the bellows flange are locked by fixing plate fasteners.

[0012] Preferably, both the left bending plate and the right bending plate are detachably connected to the fixing plate, and the left side of the left bending plate and the right side of the right bending plate are both connected to the fixing plate by bending plate fasteners.

[0013] Preferably, the right side of the scale is detachably connected to the right bending plate by a scale fastener.

[0014] Preferably, the scale fastener is a cross recessed pan head screw.

[0015] Compared with the prior art, the utility model has the following beneficial technical effects: The two fixing plates are distributed on both sides and are respectively fastened to the bellows flanges on both sides by hexagon socket head cap screws. Then, the left bending plate and the right bending plate are respectively installed on the two fixing plates, and then the scale is installed on the right bending plate, and the pointer passes through the strip-shaped groove and points to the scale line on the scale. When the length of the bellows changes, through the relative movement of the left bending plate and the right bending plate, and then through the change of the pointer pointing to the scale line, the expansion and contraction amount of the bellows can be obtained. It is directly clamped and fastened on the body flange without the need to rely on the body bolts. Compared with the common bellows scale scheme of GIS at present, which needs to be disassembled and fixed by relying on the body bolts, it is safer, more reliable and easier to implement.
