[0004] Currently, patent documents such as those disclosed in publication number CN219064372U or CN221612053U cannot perform online testing on ceramic insulators. The ceramic insulators need to be placed on a testing table, which is inconvenient to operate. Furthermore, it is not possible to re-spray ceramic PRTV coatings on insulators whose thickness does not meet the requirements after testing to improve the insulation effect of the equipment.

[0005] In view of this, this application is hereby filed. Summary of the Invention

The ceramic insulators need to be placed on the detection table, which makes operation inconvenient. In addition, it is impossible to re-spray the ceramic PRTV coating on insulators whose thickness does not meet the requirements after detection to improve the insulation effect of the equipment. The purpose of the present invention is to provide a system for detecting the quality of ceramic insulator PRTV coating, which can realize automatic online detection of the insulator PRTV coating on the surface of ceramic insulators, making operation more convenient. Once it is found that the insulator PRTV coating is less than the preset value, it means that it does not meet the requirements.

A ceramic insulator PRTV coating spraying system 9 is provided at the bottom of the unmanned aerial vehicle 2, and the ultrasonic thickness gauge 3 is detachably clamped on the surface of the insulator to be tested. A data storage library 7, used for storing a preset ceramic insulator PRTV coating thickness threshold T and a magnetic field magnitude threshold Q; The ceramic insulator PRTV coating analysis module 4 is configured to calculate the current real-time single-side thickness of the ceramic insulator PRTV coating based on the thickness of the entire ceramic insulator measured by the ultrasonic thickness gauge 3 and the ceramic insulator PRTV coating calculation model, and compare the single-side thickness with a preset ceramic insulator PRTV coating thickness threshold T. Once it is found that the ceramic insulator PRTV coating thickness threshold T is greater than the single-side thickness, the ceramic insulator PRTV coating spraying system 9 is activated to spray the surface of the ceramic insulator to be tested; A magnetic field detector 6 is used to detect the ambient magnetic field magnitude of the insulator to be measured and send the ambient magnetic field magnitude to the main control module 1 for magnetic field magnitude comparison; and based on the magnetic field intensity model, it is judged whether the magnetic field is too high. If it meets the requirements, no processing is performed; if it exceeds the preset magnetic field magnitude threshold Q in the data storage library 7, the magnetic field shield 5 is started to work for magnetic field shielding; The main control module 1 is communicatively connected to the drone 2 and the ceramic insulator PRTV coating spraying system 9; the main control module 1 is electrically connected to the ultrasonic thickness gauge 3, the ceramic insulator PRTV coating analysis module 4, the magnetic field shield 5, the magnetic field detector 6, and the data storage library 7; the power supply module 8 is connected to the main control module 1 to supply power to the main control module 1.

[0029] In this embodiment, according to the thickness of the entire ceramic insulator measured by the ultrasonic thickness gauge 3, the unilateral thickness of the current real-time ceramic insulator PRTV coating is calculated based on the ceramic insulator PRTV coating calculation model, and the unilateral thickness is compared with the preset ceramic insulator PRTV coating thickness threshold T, including: According to the thickness of the entire ceramic insulator measured by the ultrasonic thickness gauge 3, the ceramic insulator PRTV coating calculation model is retrieved to calculate the unilateral thickness M of the current real-time ceramic insulator PRTV coating; The unilateral thickness M is compared with the preset ceramic insulator PRTV coating thickness threshold T stored in the data storage library 7. When M≥T, it means that the current ceramic insulator PRTV coating meets the requirements; when M<T, it means that the current ceramic insulator PRTV coating does not meet the requirements, and the ceramic insulator PRTV coating spraying system 9 is started to spray the surface of the current ceramic insulator.

[0030] Specifically, the ceramic insulator PRTV coating calculation model is: M=(Th-Tc) / 2; Where M is the unilateral thickness of the current real-time ceramic insulator PRTV coating, Th is the thickness of the entire ceramic insulator measured by the ultrasonic thickness gauge 3, and Tc is the diameter of the wire inside the insulator.

[0031] In this embodiment, the expression of the magnetic field intensity model is: H0=Hs+Delta; Where H0 is the magnetic field intensity, with the unit of A / m; Hs is the real-time magnetic field intensity, with the unit of m, and Delta is a preset magnetic field intensity error setting value which is a constant.

[0032] In this embodiment, as Figure 2 shown, for the convenience of operating the ceramic insulator PRTV coating spraying system 9 includes a PRTV paint storage bin 901, a sub-control module 902, a high-pressure spraying pump 903, and a high-pressure nozzle 904; The sub-control module 902 is electrically connected to the high-pressure spraying pump 903. The output port of the high-pressure spraying pump 903 is connected to the high-pressure nozzle 904. The input port of the high-pressure spraying pump 903 is connected to the output port of the PRTV paint storage bin 901. And a control valve 905 electrically connected to the sub-control module 902 is also connected to the output port of the PRTV paint storage bin 901. The sub-control module 902 is communicatively connected to the main control module 1.

[0033] When the above structure works, the sub-control module 902 drives the high-pressure spraying pump 903 to work, extracts the PRTV paint in the PRTV paint storage bin 901, and sprays it onto the surface of the ceramic insulator to be repaired through the high-pressure nozzle 904, realizing the automatic spraying and feeding operation.

[0034] The specific working principle of the present invention is as follows: The ultrasonic thickness gauge 3 is used to detect the thickness of the surface of the ceramic insulator to be measured. Then, according to the ceramic insulator PRTV coating calculation formula M = (Th - Tc) / 2, the single-sided thickness of the ceramic insulator PRTV coating is calculated, and the ceramic insulator PRTV coating thickness threshold T stored in the data storage library 7 is retrieved for comparison. When M ≥ T, it means that the current ceramic insulator PRTV coating meets the requirements; when M < T, it means that the current ceramic insulator PRTV coating does not meet the requirements, and the ceramic insulator PRTV coating spraying system 9 is started to work. The sub-control module 902 drives the high-pressure spraying pump 903 to work, extracts the PRTV paint in the PRTV paint storage bin 901, and sprays it onto the surface of the ceramic insulator to be repaired through the high-pressure nozzle 904, realizing the automatic spraying and feeding operation; at the same time, the magnetic field detector 6 is used to detect the magnetic field magnitude of the measured environment and send it to the main control module 1 for magnetic field magnitude comparison, and then according to the magnetic field intensity formula 1, it is judged whether the magnetic field is too high. If it meets the requirements, no treatment is done. If it exceeds the preset magnetic field magnitude threshold Q, the magnetic field shield 5 is started to work for magnetic field shielding to avoid the influence of the magnetic field on the detection of the ultrasonic thickness gauge 3 during the detection process. Therefore, through the present invention, it is possible to realize the online detection of the automatic insulator PRTV coating on the surface of the ceramic insulator, the operation is more convenient, and once it is found that the PRTV coating of the insulator is less than the preset value, it means that it does not meet the requirements, and the ceramic insulator PRTV coating spraying system 9 is moved to the position to be coated by the unmanned aerial vehicle 2 to realize the automatic re-coating operation to improve the insulation effect of the equipment.

If leakage current is detected, a signal is sent to an operational amplifier 11. Operational amplifier 11 amplifies the data and sends it to an analog-to-digital converter 12. The analog-to-digital converter 12 converts the amplified detection voltage signal into digital test data, processes the data, and sends it to the main control module 1.

The drone 2 flies to the corresponding position according to the position sent by the GPS locator 15. Then, as the wake-up generator 14 slowly approaches the wake-up receiver 13 and the distance is less than the preset distance, the wake-up receiver 13 is started to remind, and then the ceramic insulator PRTV coating spraying system 9 is driven to work and automatically refill the insulator PRTV coating at the current position.
