Description

Technical Field

[0001] This invention belongs to the technical field of coating inspection equipment for power equipment, specifically referring to a quality inspection device for coatings on power equipment. Background Technology

[0002] As a critical component of the power system, substation equipment is exposed to complex outdoor environments for extended periods. The quality of its surface coating directly impacts the equipment's corrosion resistance and service life. Defects in the coating can accelerate corrosion, leading to decreased insulation performance and even malfunctions, threatening the safe and stable operation of the power grid. Therefore, conducting scientific and accurate quality testing of substation equipment coatings is of paramount importance.

[0003] Currently, salt spray testing is widely used to inspect the coating quality of components such as heat sinks in power equipment. However, existing technologies have significant shortcomings: First, the salt spray coverage is uncontrollable, resulting in high salt consumption, high costs, and environmental pollution. Second, heat sinks are typically laid flat in the test chamber, leading to uneven salt spray coverage in some areas and blind spots in the inspection. Third, the coating at the edges of heat sinks is often the weakest due to process limitations, making it difficult for existing equipment to perform targeted and precise corrosion inspection of the edges and surrounding areas, affecting the comprehensiveness and accuracy of the assessment. Therefore, there is an urgent need for a dedicated device capable of efficient, energy-saving, and precise inspection of heat sink edges. Summary of the Invention

[0004] To address the above issues, and in order to save materials, improve the targeted detection of weak areas in the heat sink coating, and increase detection efficiency, this invention provides a quality inspection device for the coating of power equipment. This device performs targeted detection on the relatively weak edges of the transformer heat sink coating, reducing salt spray damage while improving the salt spray's erosion efficiency on the heat sink. It simulates an outdoor environment while increasing the detection rate. The edge detection avoids the uneven erosion of some edges and surfaces during conventional flat-lying detection.

[0005] The technical solution adopted by this invention is as follows: This invention provides a quality inspection device for the coating of power equipment, including a simulated salt spray corrosion detection box, a transformer heat sink, an automatic gripping structure for the heat sink, a lifting spray device, a spray range adjustment device, and a horizontal moving structure for the spray device. The automatic gripping structure for the heat sink is engaged and fixed with the transformer heat sink, and the transformer heat sink is engaged and inserted into the simulated salt spray corrosion detection box. The horizontal moving structure for the spray device engages and slides within the simulated salt spray corrosion detection box to control the distance between the salt spray and the transformer heat sink, thereby reducing the spread range of the salt spray. The lifting spray device engages and moves up and down within the horizontal moving structure for the spray device, causing the salt spray to rise and fall along the edges of the heat sink. The spray range adjustment device is engaged and connected to the lifting spray device, adjusting the opening and closing size of the spray device according to the range of the edges and the surfaces near the edges to be inspected.

[0006] Furthermore, the automatic heat sink gripping structure includes a gripping shell, a flip gripping plate, a gripping plate positioning plate, a pressing limit plate, a limit post, and a limit spring block. The gripping shell engages with the simulated salt spray corrosion detection box. The gripping plate positioning plate is fixedly mounted on the outer wall of the gripping shell. The flip gripping plate is rotatably mounted on the gripping plate positioning plate, and the engagement point between the flip gripping plate and the gripping plate positioning plate is connected by a torsion spring. The pressing limit plate contacts the top wall of the transformer heat sink, and the limit post is fixedly mounted on the pressing limit plate. On the limiting plate, the limiting column is connected to the inner wall of the gripping shell by a spring. When the limiting plate is pressed against the top wall of the transformer heat sink, the limiting column rises, lifting one end of the flipping gripper. The flipping gripper rotates, and the other end of the flipping gripper clamps the side wall of the transformer heat sink. The limiting spring block engages and slides in the slot on the side wall of the gripping shell. The limiting spring block is connected to the gripping shell by a spring. The limiting spring block is used to limit the range of motion of the limiting column, so that the position of the flipping gripper is fixed.

[0007] Furthermore, the side wall of the limiting column is provided with prism protrusions, which cooperate with the limiting spring block to achieve the design effect of no resistance when the limiting column rises and the limiting spring block restricting the range of motion of the limiting column when it falls. Electromagnets are provided on both the limiting spring block and the inner wall of the gripping shell to change the position of the limiting spring block in the gripping shell so that the limiting column can be reset. The flipping gripping plate is provided with a resistance increasing plate to increase the frictional resistance between the equipment and the transformer heat sink.

[0008] Furthermore, the horizontal moving structure of the spraying equipment includes a cylinder, a transverse moving housing, a housing slide groove, and an anti-collision notch. The cylinder is fixedly installed inside the simulated salt spray corrosion detection chamber, the housing slide groove is fixedly installed on the bottom wall of the simulated salt spray corrosion detection chamber, the transverse moving housing slides along the housing slide groove, and the cylinder provides power to the transverse moving housing. The anti-collision notch is provided on the transverse moving housing.

[0009] Furthermore, the lifting spray device includes a screw box, a ball screw, a nut, a connecting bracket, a blower, a telescopic cylinder one, a cylinder two, a cylinder three, and a solution cup. The screw box is fixedly installed on the transverse moving machine box. The ball screw is engaged and rotated within the screw box. The nut is threadedly connected to the ball screw and slides along the screw box. The connecting bracket is fixedly connected to the nut. The blower is fixedly connected to the connecting bracket. The telescopic cylinder one is fixedly installed on the bottom wall of the blower. The cylinder two slides and engages with the telescopic cylinder one. The cylinder three slides and engages with the cylinder two. The cylinder three is fixedly installed on the transverse moving machine box. The solution cup is fixedly installed on the inner wall of the cylinder three.

[0010] Furthermore, the inner wall of the cylinder is equipped with a spray humidification device, which can be used to draw sodium chloride solution from the solution cup using an existing spray humidifier or fogger. After atomization, the solution is blown onto the heat sink by the fan at the end of the air duct.

[0011] Furthermore, there are locking blocks on the side wall of the air duct, and a lifting slot is provided on the inner wall of the transverse moving machine box. The locking blocks can move along the lifting slot in the transverse moving machine box. Locking blocks are provided on both the second cylinder and the first telescopic cylinder to prevent the first, second, and third telescopic cylinders from disintegrating during the air duct raising process.

[0012] Furthermore, the spray range adjustment device includes a bevel gear ring, a bevel gear, a turbine retaining strip, a gear ring limiting sleeve, a transverse retaining plate, and a retaining plate groove. The bevel gear is driven by a motor, and the bevel gear ring meshes with the bevel gear. The gear ring limiting sleeve is fixedly connected to the motor below the bevel gear ring via a connecting plate. The turbine retaining strip engages and rotates within the gear ring limiting sleeve, and the gear ring limiting sleeve is engaged and rotated with the bevel gear ring. The turbine retaining strip is fixedly mounted on the bevel gear ring, and the retaining plate groove is mounted on the gear ring limiting sleeve. The transverse retaining plate engages and slides within the retaining plate groove, and is engaged and connected with the turbine retaining strip. By rotating the bevel gear ring, the position of the transverse retaining plate on the retaining plate groove can be changed. Both the bevel gear ring and the gear ring limiting sleeve have a ventilation hole at their center.

[0013] Furthermore, the bevel gear ring is engaged and rotatably connected to the air duct to ensure that the rotation of the bevel gear ring will not change the position of the air duct. The outer wall of the gear ring limiting sleeve is provided with a locking block, and the inner wall of the transverse moving housing is provided with a second lifting slot. The gear ring limiting sleeve slides along the direction of the second lifting slot to ensure that the gear ring limiting sleeve can also be regularly adjusted during the lifting and lowering of the air duct.

[0014] Furthermore, the spray range adjustment device also includes a nozzle ring, an adjusting clamp, a front clamp slot, a combined shielding plate, a shielding plate concealment slot, and a shielding plate limiting slot. The nozzle ring is fixedly mounted on the toothed ring limiting sleeve. The front clamp slot is disposed on the nozzle ring. The adjusting clamp is fixedly mounted on the transverse sliding plate and slides along the front clamp slot. The shielding plate concealment slot is disposed on the adjusting clamp. The shielding plate limiting slot is disposed on the inner wall of the nozzle ring. The combined shielding plate engages and slides within the shielding plate concealment slot and also engages and slides within the shielding plate limiting slot. The combined shielding plate and the shielding plate concealment slot are connected by a spring. By sliding the combined shielding plate on the inner wall of the nozzle ring, the depth of the combined shielding plate entering the shielding plate concealment slot is changed.

[0015] Furthermore, the simulated salt spray corrosion testing chamber is equipped with a pressure sensor and a controller. After the transformer heat sink is placed in the simulated salt spray corrosion testing chamber, the pressure sensor receives the signal, converts the signal into an electrical signal, and transmits it to the controller. The controller controls the cylinder to extend, pushing the transverse housing towards the location of the transformer heat sink. The top wall of the simulated salt spray corrosion testing chamber is equipped with a storage slot for placing the transformer heat sink. A scanning electron microscope can be placed on the storage slot. At the same time, a display screen is placed on the top wall of the simulated salt spray corrosion testing chamber. The display screen and the scanning electron microscope are connected by a data cable. When the transformer heat sink is removed from the storage slot, the edges of the transformer heat sink can be scanned to quickly compare the differences in corrosion resistance after different coating processes or accelerated corrosion tests. The top wall of the simulated salt spray corrosion testing chamber is equipped with a ventilation hose for collecting toxic gases inside the simulated salt spray corrosion testing chamber, which are then rendered harmless.

[0016] Furthermore, the front end of the adjusting clamp is set as an inclined surface, which can better fit the edge of the transformer heat sink. Ventilation holes are provided on the side walls of the transverse chassis and the simulated salt spray corrosion detection box to balance the internal air pressure of the simulated salt spray corrosion detection box.

[0017] Furthermore, the nozzle ring is provided with a triangular groove for fitting the edge of the transformer heat sink.

[0018] Preferably, the front end of the adjusting clamp is set as a 45° slope.

[0019] Preferably, the spray humidification equipment is eliminated and replaced with a heater placed on the bottom wall of the solution cup, so as to simulate the salt spray test by causing the salt spray to evaporate.

[0020] This solution provides a quality inspection device for the coating of power equipment, which has the following advantages: (1) The present invention controls the distance between the salt spray and the transformer heat sink by using the horizontal moving structure of the spraying equipment, which significantly reduces the salt spray diffusion range, reduces the salt spray consumption, saves costs and is more environmentally friendly; (2) The lifting spray device can spray salt spray along the edge of the heat sink by lifting and lowering. Combined with the spray range adjustment device, the spray opening and closing size can be precisely adjusted to achieve efficient and directional corrosion detection of the edge and surrounding area. (3) The automatic heat sink gripping structure achieves rapid and stable clamping and release of the heat sink through mechanical linkage and limit design, thereby improving the automation level and operational safety of the testing process; (4) The device integrates a scanning electron microscope interface and a gas recovery system, which can perform surface analysis immediately after detection and treat harmful gases to be harmless, thereby improving the comprehensiveness of detection and environmental friendliness.

[0034] The bevel ring 30 is engaged and rotated with the air duct 23.

The ring limiting sleeve 33 slides along the lifting slot 36.

[0035] The spray range adjustment device 5 also includes a nozzle ring 37, an adjusting clamp 38, a front clamping groove 39, a combined shielding plate 40, a shielding plate concealing groove 41, and a shielding plate limiting groove 42. The nozzle ring 37 is fixedly installed on the toothed ring limiting sleeve 33. The front clamping groove 39 is provided on the nozzle ring 37.

The combined shielding plate 40 engages and slides in the shielding plate concealing groove 41 and in the shielding plate limiting groove 42.

[0036] The simulated salt spray corrosion testing chamber 1 is equipped with a pressure sensor 43 and a controller 44. The top wall of the simulated salt spray corrosion testing chamber 1 is equipped with a storage slot 45 for placing the transformer heat sink 2. The top wall of the simulated salt spray corrosion testing chamber 1 is equipped with a ventilation hose.

[0037] The front end of the adjusting clamp 38 is set as an inclined surface, and ventilation holes are provided on the side walls of the transverse moving housing 16 and the simulated salt spray corrosion detection chamber 1.

[0038] The nozzle ring 37 has a triangular groove.

[0039] In practical use, first fix the transformer heat sink 2, place the gripping shell 7 above the transformer heat sink 2, and the transformer heat sink 2 stands up. Press the pressing limit plate 10 against the top wall of the transformer heat sink 2. The pressing limit plate 10 receives the support force from below and rises. At the same time, the limiting column 11 rises. During the rising process of the limiting column 11, it pushes the limiting spring block 12 to move into the slot on the inner wall of the gripping shell 7. The limiting column 11 rises and squeezes the flipping gripping plate 8, causing one end of the flipping gripping plate 8 to tilt up and the other end to rotate and approach the direction of the transformer heat sink 2. After the gripping plate positioning plate 9 is fixed relative to the transformer heat sink 2, the prism protrusion 13 on the side wall of the limiting column 11 contacts the limiting spring block 12 and is supported by the limiting spring block 12. The limiting column 11 cannot move downward due to the tension of the spring, thereby ensuring the stability of the transformer heat sink 2 in the gripping structure. The transformer heat sink 2 is inserted into the storage slot 45 on the upper wall of the simulated salt spray corrosion detection chamber 1. The transformer heat sink 2 enters the depth of the simulated salt spray corrosion detection chamber 1 and comes into contact with the pressure sensor 43 at the bottom. The pressure sensor 43 receives the pressure from the transformer heat sink 2 and converts the pressure into an electrical signal. The electrical signal is transmitted to the controller 44. The controller 44 controls the cylinder 15 to extend and pushes the transverse machine box 16 toward the direction of the transformer heat sink 2, so that the nozzle ring 37 is tightly attached to the transformer heat sink 2. After the nozzle ring 37 is in close contact with the transformer heat sink 2, the spray range is adjusted, the bevel gear 31 rotates, and the bevel ring 30 rotates under the meshing action. Affected by the turbine clamping strip 32 structure on the surface of the bevel ring 30, the transverse clamping plate 34 is displaced. Since the clamping plate slot 35 restricts the direction of movement of the transverse clamping plate 34, when the bevel ring 30 rotates, the transverse clamping plate 34 will drag the adjusting clamp 38 to move horizontally and clamp the edge of the heat sink. When the adjusting clamp 38 moves, the combined shielding plate 40 slides on the arc-shaped inner wall of the nozzle ring 37 due to the movement of the adjusting clamp 38. Restricted by the arc-shaped inner wall of the nozzle ring 37, the combined shielding plate 40 moves up and down in the shielding plate hiding groove 41 on the adjusting clamp 38. Under the combination of the adjusting clamp 38, the combined shielding plate 40 and the nozzle ring 37, the spraying area of ​​the salt spray is changed. The spray humidifier draws sodium chloride solution from solution cup 27, and after being pressurized and heated to form salt mist, it is blown by the fan in the air duct 23 to flow to the transformer heat sink 2; Alternatively, the solution cup 27 can be heated with a heater, causing the solvent to evaporate into a mist, which can then be sprayed onto the heat sink. To detect salt spray at different heights of the edges of the transformer heat sink 2, the ball screw 20 rotates, the nut 21 slides in the screw box 19, and the connecting bracket 22 pulls the telescopic cylinder 1 24 to move up and down. As the telescopic cylinder 1 24 moves up and down, the air duct 23 drives the spray range adjustment device 5 to move up and down. The cylinder 25 and cylinder 3 26 slide and extend to ensure that the salt spray can be effectively delivered to the air duct 23. After a period of salt spraying, the heat sink needs to be tested. The transformer heat sink 2 is pulled out from the storage slot 45. When the transformer heat sink 2 is pulled out from the storage slot 45, a scanning electron microscope is placed on the storage slot 45 to scan the heat sink. The acquired data is directly transmitted to the display. After the test is completed, the heat sink is removed from the heat sink automatic gripping structure 3. The two sets of electromagnets inside the gripping housing 7 are attracted after being energized. The limiting spring block 12 is hidden inside the gripping housing 7. The limiting column 11 is separated from the flipping gripping plate 8 under the action of the spring. The flipping gripping plate 8 is separated from the transformer heat sink 2, and the transformer heat sink 2 is released. During the salt spray test, the ventilation hose extracts excess salt spray from the simulated salt spray corrosion detection chamber 1 for neutralization.
