Problems solved by technology

However, its specific measurement methods have been carried out manually, but in the process of manual measurement data, there are inevitably some human instincts that affect the measurement results.
For example: when holding the measuring rod (probe) or Pitot tube measuring rod of the anemometer with human hands,

Abstract

The invention relates to a Pitot tube and wind-velocity indicator probe fixing device. The device comprises a plug (1) and a pitot tube or measuring rod fixing frame (2), wherein the plug (1) is connected with the Pitot tube or measuring rod fixing frame (2). The device can improve the safety of the test personnel and reduce the labor intensity of the test personnel. In the leveling process of thePitot tube, some test positions are at high altitude, and some test positions are in areas where people cannot stand or stay. The device will give full play to the advantages thereof once encountering the circumstance. The whole test process can be completed by only installing the device once, thereby eliminating the fatigue process of holding a measuring rod by the personnel in situ for a long time, greatly reducing the labor intensity of the test personnel, and improving the personal safety of the test personnel at the same time.

Description

technical field [0001] The invention is used in the primary air pipe leveling test project in the cold ventilation test project of the boiler carried out during the boiler debugging of the power plant in the electric power industry. Background technique [0002] The fixation of the sampling device during the boiler cold ventilation test has always been a problem that affects the accuracy of on-site measurement. Whether it is a pitot tube, a portable anemometer, or a multi-channel anemometer, there is a problem of inaccurate positioning of the sampling probe. The advantages of the device are: 1. The positioning is accurate, and the measurement accuracy can be guaranteed in each dimension of the airflow. 2. The sealing performance is good, no matter for the dust-laden airflow in the cold state or the two-phase flow with coal powder in the hot state, it can guarantee tightness. [0003] The principle of wind speed measurement is as follows: [0004] [0005] Q=3600Avm 3 / ...
