Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating adhesion testing technology, specifically a coating adhesion testing device for a molten salt absorber. Background Technology
[0002] Molten salt absorbers are one of the core components of solar thermal power generation systems, especially widely used in tower molten salt technology. They reflect sunlight to the absorber at the top of the absorber tower through a large-scale heliostat array, converting light energy into heat energy and storing it in molten salt. Molten salt absorbers typically adopt a tube bundle structure, with the outer wall of the tube receiving solar radiation and molten salt flowing inside the tube to complete the heat exchange process.
[0003] The coating of molten salt absorbers is one of the core technologies for improving photothermal conversion efficiency and extending equipment life. Furthermore, the coating adhesion testing device for molten salt absorbers is a key device for evaluating the adhesion performance of coatings on the surface of molten salt absorbers. Its design and function must meet the requirements for accurate measurement of the bonding strength between the coating and the substrate.
[0004] When testing the adhesion of coatings on molten salt absorbers, the samples need to be clamped and fixed. Existing coating adhesion testing devices often result in excess thickness during clamping due to inconsistent sample thicknesses, leading to inaccurate test data. Therefore, those skilled in the art have provided a coating adhesion testing device for molten salt absorbers to address the problems mentioned in the background art. Utility Model Content
[0005] Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a coating adhesion testing device for molten salt absorbers. This device solves the problem that existing coating adhesion testing devices often have thickness allowances when clamping samples due to inconsistent sample thickness specifications, which can lead to inaccurate test data.
[0007] Technical solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a coating adhesion testing device for a molten salt absorber, comprising a base plate, a bracket mounted on one side of the base plate, a top plate above the base plate, a first hydraulic rod mounted on the bottom side of the top plate, a first motor mounted on the base plate, a bidirectional screw connected to the output end of the first motor, a clamping plate threaded onto the bidirectional screw, a through groove on the clamping plate, a slot on the top plate, a second hydraulic rod mounted on the lower side of the bracket, and a cutter head assembly mounted on the bottom output end of the second hydraulic rod.
[0009] Preferably, the top plate is slidably engaged with the clamping plate via a slot, and the clamping plate is slidably inserted into the top plate via a through slot. When a coating sample is placed on the top plate, the first motor drives the bidirectional screw to move the two clamping plates relative to each other, thereby clamping and limiting the coating sample.
[0010] Preferably, the top plate is connected to the bottom plate via a first hydraulic rod. As the two clamping plates gradually clamp the coating sample, the first hydraulic rod drives the top plate to rise, thereby squeezing the upper edge of the coating sample on the top plate against the top groove of the clamping plate, thus pressing the coating sample of different thicknesses against each other, and fixing the coating sample with the clamping of the clamping plates.
[0011] Preferably, the bracket has a sliding groove, and a limit block is provided in the sliding groove. The bottom of the limit block is fixedly connected to the second hydraulic rod.
[0012] Preferably, a second motor is installed on the bracket, and the output end of the second motor drives a threaded rod. The threaded rod is threadedly connected to a limiting block. The second hydraulic rod on the bracket extends and retracts to cooperate with the cutter head assembly to test the coating sample. A sliding groove is provided on the bracket, and a limiting block is set in the sliding groove. The bottom end of the limiting block is connected to the second hydraulic rod. When the second motor drives the threaded rod to rotate, the threaded limiting block can drive the second hydraulic rod to move laterally, thereby moving the cutter head assembly to perform a sliding test on the coating sample.
[0013] Beneficial effects
[0014] Compared with the prior art, this utility model provides a coating adhesion testing device for molten salt absorbers, which has the following advantages:
[0015] Through design, the coating adhesion testing device of this practical internal molten salt absorber consists of a base plate, a top plate, and a support.
