Description

Technical Field

[0001] This invention belongs to the technical field of wind speed testing fixtures, and relates to a wind speed testing fixture for use inside a gas quenching furnace. Background Technology

[0002] High-temperature and high-pressure gas quenching furnaces are scientific instruments used in materials science and have wide industrial applications. Their principle involves first introducing nitrogen into the furnace to start the fan. Once the fan is running normally, gas is then introduced into the furnace, cooled through a heat exchanger, and then delivered through ductwork to quench the workpiece. However, because the gas quenching furnace operates in a completely enclosed environment, it is difficult to understand the gas flow within the furnace. Furthermore, due to the high fan speed and overall rapid gas flow, the flow field is complex, making it difficult to measure the overall flow field inside the furnace using simple speed measuring devices. Therefore, it is urgently necessary to design a fixture for testing the internal wind speed of a gas quenching furnace that can simultaneously measure multiple points, allows remote determination of the test points, has a large detection range, a high degree of automation, and has a built-in independent power supply to export wind speed data in a closed environment, effectively reducing measurement time, minimizing the impact of time factors on the measurement results, and improving measurement accuracy.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses an automated tracked wind speed detection device and method for calculating the uniformity coefficient of boiler air distribution [Application No.: 201910639187.2]. The device uses a signal transmitter and a signal receiver to communicate and send control commands to the tracked wind speed detection device controller. The computer controls the movement trajectory of the device on the grate. The signal transceiver communicates with the signal transmitter. The current detection module is used to detect the power generation current of the small wind turbine. The computer receives the test data from the current detector and converts it into wind speed distribution data. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a tooling for testing the internal wind speed of a gas quenching furnace.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions:

The electromagnets are tightly fixed to the main body of the gas quenching furnace, and the electromagnets and electromagnetic telescopic rods are arranged alternately.

[0013] In the aforementioned fixture for testing the internal wind speed of a gas quenching furnace, the fixture mounting base is further provided with a first control module, a first wireless transceiver module, and a first energy storage module.

The measured wind speed is transmitted to the positioning control part 5 and then to an external receiving device. The fixed rotating part 3 controls the angle of the telescopic speed measuring component 4, and the positioning control part 5 controls the length of the telescopic speed measuring component 4. The test point is remotely determined. The detection range is large, the degree of automation is high, and the built-in independent power supply exports the wind speed data in a closed environment, effectively reducing the speed measurement time, reducing the impact of time factors on the speed measurement results, and improving the speed measurement accuracy.
