Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic detection, in particular to an ultrasonic scanning vehicle for wind power generation blades. Background Art

[0002] As an environmentally friendly and renewable new energy form, wind power has developed very rapidly in recent years and has received widespread international attention. my country is rich in wind energy resources, with a developable wind energy reserve of about 1 billion kilowatts. By the end of 2003, the country's wind power installed capacity was about 567 million kilowatts: At the end of 2014, the National Energy Administration planned a total offshore installed capacity of 10.53 million kilowatts. However, as of the end of July 2015, the cumulative installed capacity was 61,000 kilowatts, which is far from the planned total installed capacity. This means that the development of domestic wind power will enter a rapid development mode.

[0003] "Wind turbine blades" are the intermediate link that directly converts wind energy into mechanical energy. They are also the key origin of the entire energy conversion process and play a vital role in the entire wind turbine generator set. Therefore, its health is directly related to the implementation and conversion efficiency of wind power generation. With the increase of installed capacity, the volume of blades tends to increase. Considering the energy conversion efficiency, its own weight is restricted. For this reason, a large number of non-metallic organic materials and composite materials are used in the selection of materials for wind turbine blade manufacturing. On the basis of ensuring sufficient strength and rigidity, the two major problems of "efficiency" and "weight" have found a "balance point" to solve. However, the selection of organic materials and composite materials to use bonding technology to manufacture curved blades also introduces the problem of quality monitoring, that is: how to ensure that the production efficiency of blades is steadily improved without sacrificing the factory quality. Among them, the bonding quality of glass fiber or carbon fiber composite materials located at the keel of the blade and the bubble impurity defects inside the glass fiber material are often the top priority of monitoring.

[0004] The length of a wind turbine blade is about 100 meters. It is very time-consuming and labor-intensive to detect defects in the fiberglass and adhesive bonding inside it. Using an electric forklift (including an electric forklift) for auxiliary inspection can reduce the number of inspectors, reduce labor intensity, and improve inspection efficiency.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0027] In one embodiment, a wind turbine blade ultrasonic scanning vehicle, see Figure 1 to Figure 3 , including an electric forklift 1, and further comprising:

[0028] A scanning frame 4, wherein the scanning frame 4 is arranged at one side of the electric forklift 1, the electric forklift 1 is movably connected to the scanning frame 4, a suction cup 2 is arranged at the side of the scanning frame 4, and one end of the suction cup 2 is movably connected to the scanning frame 4;

[0029] A wastewater recovery tank 3 is provided on one side of the electric forklift 1, a clean water tank 7 is provided on one side of the wastewater recovery tank 3, and the clean water tank 7 is provided on one side of the electric forklift 1, and an integral water collecting bucket 101 and an ultrasonic probe shoe block 10 are provided on one side of the scanning frame 4.

[0030] For further information, see Figure 1 to Figure 3 A push-out mechanism 9 is provided on one side of the electric forklift 1 , and the push-out mechanism 9 is connected to the electric forklift 1 , and the push-out mechanism 9 is connected to the scanning frame 4 .

[0031] For further information, see Figure 1 to Figure 3 A flipping mechanism 8 is provided on one side of the electric forklift 1 , and the flipping mechanism 8 is connected to the ejection mechanism 9 , and the flipping mechanism 8 is connected to the scanning frame 4 through a side steering shaft 5 .

[0032] For further information, see Figure 1 to Figure 3The suction cup 2 is symmetrically arranged with respect to the scanning frame 4.

[0033] For further information, see Figure 1 to Figure 3 An electric control cabinet 6 is provided on one side of the electric forklift 1 , and the electric control cabinet 6 is electrically connected to the electric forklift 1 , the turning mechanism 8 and the pushing mechanism 9 .

[0034] In this embodiment, by symmetrically arranging the suction cups 2 about the scanning frame 4, it is possible to achieve that after the suction cups on both sides 2 contact the surface of the blade, the contact of the suction cups on either side is completed by the force pushed out by the pushing mechanism to achieve the posture of the scanning frame 4 being parallel to the blade, so as to facilitate the contact scanning ultrasonic test of the blade by the scanning frame 4.

[0035] The water collecting bucket 11 is designed together with the Olympus ultrasonic C-scan probe shoe block 10, and the upper and lower mechanical connections are moved together with the probe for measurement, and the wastewater is collected and recycled from the water collecting bucket 11 to the wastewater tank by an air-liquid pump.

[0036] The electric forklift 1 is manually or automatically moved to the starting measurement position, the actuator adjusts the scanning frame 4 to the direction of the upper and lower positions of the blade parallel to the blade surface, the actuator pushes the scanning frame 4 so that one of the two suction cups 2 first contacts the blade surface, for example, the suction cup 1 contacts the blade surface, the actuator continues to push out so that the angle is 0 degrees, and the scanning frame 4 starts to scan the blade in the X and Y directions with the ultrasonic probe;

[0037] The X and Y axis ultrasonic scanning frame is transplanted onto the electric forklift 1, and the scanning frame 4 is used to position the blade by using the lifting, lowering, forward and backward, left and right movement functions of the electric forklift 1. The scanning frame 4 is then used to perform ultrasonic scanning on the blade in the X and Y directions to complete the scanning of an area of ​​the blade, and then continue to move forward and perform another scan in the X and Y directions until the blade completes the scanning of all positions to be measured in all length directions.

[0038] The design method of the probe boot block 10 of the wastewater recovery system with a water collecting bucket 11 and a gas-liquid pump to recover the wastewater from the water pipe to the wastewater recovery tank 3 solves the problem of wastewater recovery in the scanning frame 4. There is no need to control the water level. The gas-liquid pump is turned on at the beginning of the scan and turned off at the end of the scan water spray. At the same time, the design of the small recovery bucket, that is, the size of the recovery bucket is only half the size of the blade probe, can meet the needs of measuring the tiny curved surface of the blade. The water collecting bucket 11 does not interfere with the blade surface, and can measure the large curvature position.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
