Portable recorder supporting device with signal shielding function

Abstract

The invention discloses a portable recorder supporting device with a signal shielding function, and relates to the technical field of recorders, the portable recorder supporting device comprises an upper casing and a lower base, and further comprises a positioning assembly, a bearing assembly and a lifting assembly, the upper casing is internally provided with a cavity, the upper casing is internally provided with a blocking assembly, the lower base is internally provided with a containing cavity, an ejection mechanism is arranged in the containing cavity, four supporting legs are arranged at the bottom of the lower base, the ejection mechanism comprises a linkage assembly and two reset assemblies, ventilation openings are formed in the top of the lower base and the bottom of the upper machine shell, a blowing and separating unit is arranged at the inner top of the lower base, and a pair of doors is arranged on the front side wall of the upper machine shell. The operation is convenient and rapid, and the operation requirements of operators with different heights can be met; when the bearing assembly works, the wave recorder on the bearing plate is driven to rotate, so that the purpose of adjusting the angle of the wave recorder is achieved, free switching of overall fixed supporting and walking can be controlled, and the overall functionality and practicability are improved.

Description

technical field [0001] The invention relates to the technical field of oscilloscopes, in particular to a portable oscilloscope supporting device with a signal shielding function. Background technique [0002] The oscilloscope records the transient and steady-state analog and event information of generators, transformers, power transmission lines, power stations, and power plants, monitors the operation of the power system, saves test data, records and captures fault information, and provides a basis for studying the operation mode of the power grid. It is an important instrument that provides a basis for evaluating the performance of protection devices. It has the advantages of good portability, simple structure and low cost. It can be widely used in various voltage levels of power transmission and transformation lines, transformers and protection and other power transmission and transformation equipment, generators It is suitable for occasions where fault monitoring, wavefo...

Problems solved by technology

[0003] When the oscilloscope is in use, due to the different types of oscilloscopes, the size and size of the oscilloscope will be different accordingly. The fixed support devices of the existing oscilloscopes are difficult to meet the fixed needs of different types of oscilloscopes, so most of them are placed in The operation is carried out on the ground, but it is very inconvenient for the staff to put it on the ground to squat up many times, and most of the existing fixed support devices of the oscilloscope directly fix the oscilloscope on the fixed frame, which cannot be adjusted according to different operators. Height adjusts the height of the fixed frame in real time, and during the mobile operation, the wave recording instrument cannot be effectively protected, the function is relatively single, and the angle of the wave recording instrument cannot be adjusted at the same time
