Description

Technical Field

[0001] This invention relates to the field of wind power new material testing technology, specifically to a corrosion testing device for offshore wind power materials. Background Technology

[0002] Corrosion testing of offshore wind power materials is a core component in ensuring the long-term reliable operation of wind power equipment. Salt spray testing can be used to test the corrosion of wind turbine blade coatings. Salt spray testing assesses the ability of materials and their protective layers to withstand salt spray corrosion.

[0003] Existing salt spray testing equipment inevitably causes a certain position of the sample to be in prolonged contact with the supporting or fixed structure when placing the sample. During the salt spray test, liquid tends to accumulate at the fixed contact point of the sample, leading to localized abnormal corrosion of the sample and affecting the corrosion test results of wind power materials. Summary of the Invention

[0004] The purpose of this invention is to provide a corrosion testing device for offshore wind power materials, in order to solve the problem in the prior art that when placing samples, it is unavoidable that a certain position of the sample will be in fixed contact with the supporting structure or fixed structure for a long time. During the salt spray test, the fixed contact point of the sample is prone to liquid accumulation, which leads to local abnormal corrosion of the sample and affects the corrosion test results of wind power materials.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a corrosion testing device for offshore wind power materials, comprising a housing, a cover installed on the top of the housing, a salt spraying mechanism installed inside the housing, and multiple supporting mechanisms, wherein the supporting mechanisms include: The mounting base is installed inside the housing and has a U-shaped structure. The base support assembly includes multiple electric push rods installed inside the fixed base and a base support plate installed at the extended end of the electric push rods, with a sample placed on top of the base support plate; The movable clamping assembly has two sets, which are respectively set on both sides of the sample. The movable clamping assembly includes multiple one-way clamping parts installed inside it along the height direction of the fixed base, a drive block set below the one-way clamping parts, and a lifting part for driving the drive block to rise and fall. The one-way clamping parts include multiple clamping rods installed inside it along the length direction of the fixed base and a linkage part installed at one end of the multiple clamping rods. The linkage self-cleaning component is connected to the clamping rod and is used to drive the clamping rod to rotate.

[0006] Furthermore, the top of the bottom support plate is provided with multiple positioning grooves, and the sample is placed inside the positioning grooves.

[0007] Further, the linkage part comprises a movable block rotationally connected to one end of the plurality of clamping rods and a movable groove formed in the movable block, and first inclined grooves are formed in the top of one side and the bottom of the other side of the movable block, and the two first inclined grooves are in communication with the movable groove.

[0008] Further, a plurality of springs are fixedly connected to the outer wall of the side of the movable block away from the clamping rod, and the other end of the spring is fixedly connected to the inner wall of the fixed seat.

[0009] Further, an electromagnet is arranged on one side of the movable block, the movable block has magnetism, and the electromagnet is arranged on the inner wall of the fixed seat and cooperates with the movable block.

[0010] Further, second inclined grooves are formed in the top and the bottom of the driving block, and the second inclined grooves are matched with the first inclined grooves.

[0011] Further, the lifting part comprises a lead screw threadedly connected to the inside of the driving block, a motor arranged on the inner wall of the bottom of the fixed seat, and two guide rods slidingly connected to the inside of the driving block. The lead screw is rotationally connected to the inside of the fixed seat, and the lead screw and the output shaft of the motor are in transmission connection through a belt wheel mechanism. The guide rods are fixedly connected to the inside of the fixed seat.

[0012] Further, the linkage self-cleaning assembly comprises a spiral groove formed in the outer surface of the clamping rod and a fixed strip fixedly connected to the inner wall of the fixed seat. The fixed strip is fixedly connected with a fixed rod on the outer wall of the side close to the clamping rod, the other end of the fixed rod is in a semispherical structure, and extends into the inside of the spiral groove.

[0013] Compared with the prior art, the offshore wind power material corrosion test equipment has the following beneficial effects: By driving each layer of clamping rods to be away from the sample in sequence and then returning, the problem of large difference in corrosion between the sample clamping position and other positions is avoided, and under the premise of ensuring normal fixation of the sample, the accuracy of corrosion of each region of the sample is effectively improved. When the clamping rod is driven to move, the clamping rod rotates while moving through the limiting effect of the fixed rod in the spiral groove, and the centrifugal force generated when the clamping rod rotates shakes off the liquid attached to the outside of the clamping rod, thereby avoiding the problem that the end of the clamping rod close to the sample gathers liquid, causing local abnormal corrosion of the sample when the clamping rod contacts the sample.

When the lead screw 17 rotates clockwise, it drives the driving block 8 to move upwards along the outer wall of the two guide rods 19. When the second inclined groove 16 at the top of the driving block 8 abuts against the first inclined groove 13 at the bottom of the movable block 11, the movable block 11 starts to slide to the right, and the spring 14 is compressed.

Thus, when the driving block 8 moves downwards, each layer of clamping rods 9 is also sequentially driven to move away from the sample and then reset. After the salt spray treatment is completed, each layer of electromagnet 15 is energized. After driving each layer of movable block 11 away from the sample, the electromagnet 15 magnetically attracts and fixes each layer of movable block 11 in sequence, thereby driving each layer of clamping rod 9 to move away from the sample 7 in sequence, releasing the clamping and fixation of the sample 7, so as to facilitate the staff to take out the sample 7, and also facilitate the staff to put the next batch of sample 7.
