Fan device capable of identifying blade surface failure

Abstract

The invention relates to the technical field of fan device detection, in particular to a fan device capable of identifying a blade surface failure. The fan device capable of identifying the blade surface failure comprises a fan chamber arranged on the top of a stand column, wherein fan blades are arranged at the front end of the fan chamber, a camera shooting device is arranged at the rear end of the top surface of the fan chamber, and connected with a data acquisition control device, the data acquisition control device is connected with a failure identification device, and a receiving and transmitting device is arranged on the fan chamber, and connected with a center control device. According to the fan device capable of identifying the blade surface failure, the fan blades can be continuously inspected through the fan device, flaws in an existing maintenance mode are effectively avoided, the number of problems appearing during maintenance is reduced, the difficulty of manual detection is reduced, and the defects in the prior art are overcome.

Description

technical field [0001] The invention relates to the technical field of fan equipment detection, in particular to a fan equipment capable of identifying faults on the blade surface. Background technique [0002] In the prior art, the fan blade is one of the most critical components of the entire wind power generator system, and is the key to converting wind energy into rotational kinetic energy for driving the generator. The rotating diameter of the large fan blades has reached 120m. Wind power generation is mostly built in areas with large wind volume, high altitude, and harsh environment. The blades are always eroded by the medium in the air, and the failure rate of fan blades accounts for one-third of the wind turbine units. If the abnormality of the blade is not found in time, the fault will expand, that is, the damage will expand. The main fault types are cracks, bulges, pitting, sand holes, wear and so on. At present, there are mainly two methods for the detection an...

AI Technical Summary

Problems solved by technology

This method causes many blades to be in a sick working state. As the running time increases, the accumulation of problems gradually increases. Due to the failure of the blades, the fan shuts down several times within a year.

Most of the accidents in wind farms occur during the wind power generation period. Serious accidents require the power generation to be stopped, which brings huge economic losses to the wind farm

Second, regular maintenance

[0003] (1) The cost of regular maintenance is high and some maintenance is interventional, which has a certain adverse effect on the state of the equipment itself;

[0004] (2) Although special inspections have been added in actual work, such as special inspections before and after strong winds, special inspections after lightning strikes, etc., to make up for the blank period of periodic inspections, these special inspections are mainly carried out according to climatic conditions, not According to the continuous real-time monitoring of the actual operating status of the fan, the fan equipment may still fail during the equipment maintenance interval

[0005] (3) The manual inspection in the two maintenance methods generally uses a camera and a telescope to collect images. The inspection personnel are under the fan, waiting for the fan to stop, looking up to shoot and observe, and the capture is difficult and incomplete.

This utility model discloses the main control device of wind power equipment, and does not propose how to carry out safety monitoring and timely maintenance on the premise of ensuring the safe operation of wind power generation equipment when the surface of the fan blade of the wind power generation equipment fails or is affected by a dangerous event
