Description

Technical Field

[0001] The utility model relates to the technical field of electric power, in particular to a portable device for electric power supervision. Background Art

[0002] Electric power is an energy source that uses electric energy as power. Discovered in the 1870s, the discovery and application of electric power set off the second industrialization climax. It has become one of the three technological revolutions that have taken place in the world since the 18th century, and since then technology has changed people's lives. The large-scale power system that emerged in the 20th century is one of the most important achievements in the history of human engineering science. It is a power production and consumption system composed of links such as power generation, power transmission, power transformation, power distribution, and power consumption. It converts the primary energy in nature into electric power through mechanical energy devices, and then supplies the electric power to each user through power transmission, power transformation, and power distribution.

[0003] After retrieval, it is found that the Chinese patent with the application number 202322060076.0 discloses a portable device for electric power supervision, including a monitor for electric power monitoring; a box cover rotatably installed on the monitor; a support assembly hinged between the monitor and the box cover; and a laying assembly movably installed in the box cover. In the utility model, after the box cover is flipped open from the monitor, the laying assembly is unfolded on the box cover, and then the recording paper is placed on the laying assembly, so that the data monitored by the monitor can be recorded, improving the convenience of data recording outdoors. And when the recording paper is placed on the laying assembly, by pulling the clamping plate to drive the insertion rod to slide out, and then placing the paper between the clamping plate and the flat plate, the paper can be fixed on the flat plate, so that the paper will not be blown up during recording and writing.

[0004] The above-mentioned utility model has the following problems:

There are many sundries and electric power engineering supplies at the work site, which may cause the monitor or the staff to collide, resulting in damage to the monitor. In the above application, the monitor does not have a portable mechanism. Carrying it by hand or in a backpack cannot effectively protect and dissipate heat from the monitor, and it will shake when the staff walks, resulting in errors in the monitor detection.

[0006] Therefore, those skilled in the art provide a portable device for electric power supervision to solve the problems raised in the above background art. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a portable device for electric power supervision to solve the problems raised in the above background art.
