Description

Technical Field

[0001] The invention relates to the technical field of microwave detection, and in particular to a microwave detector and a detection method for producing porcelain insulators. Background Art

[0002] Porcelain insulators are electrical insulators made of electrical ceramics, which are widely used in power transmission lines and electrical equipment to isolate live parts and prevent current from short-circuiting through non-conductive parts. Its main features are good electrical insulation performance, weather resistance and mechanical strength, and it can maintain stable insulation performance for a long time in various harsh outdoor environments.

[0003] When firing porcelain insulators and other porcelain parts, there may be iron impurities inside the porcelain parts. The iron impurities may come from the metal iron that has not been completely screened out of the raw materials themselves, or from metal knives or kilns during the processing process. In the fired porcelain parts, if the iron impurities exist in an aggregated state, they will form iron spots or black spots, or even melt holes of metal iron, thereby reducing the mechanical strength and electrical insulation performance of the electric porcelain products. Therefore, it is necessary to detect the iron impurities in the porcelain insulators. The existing iron impurity detection generally uses microwaves to heat the porcelain insulators first, in which the temperature rise of the part with high iron content will be more obvious. At this time, the temperature changes of various parts of the porcelain insulator can be detected by an infrared thermal imaging detector, thereby detecting the iron impurity defects in the porcelain insulator. However, the bottom tray of the existing microwave detector is generally made of tempered glass to withstand the high temperature during microwave heating. If the porcelain insulator is placed directly, the porcelain insulator will contact the tray over a large area, so that part of the heat of the porcelain insulator itself will be transferred to the tray due to heat conduction after being heated by microwaves, resulting in the temperature change of the porcelain insulator itself being affected, thereby causing the detection result of the infrared thermal imaging detector to be biased, and the overall detection result is not accurate enough.

[0004] Based on the above situation, the present invention proposes a microwave detector and a detection method for porcelain insulator production with more accurate detection results. Summary of the invention

Electric slide rails 15 are fixedly connected to the left and right sides of the chassis 1. A movable top frame 14 is slidably connected between the front sides of the two electric slide rails 15. A mounting frame 19 is fixedly connected to the left and right sides of the chassis 1. A first top block 16 is slidably connected to the top of the mounting frame 19. The movable top frame 14 is squeezed and matched with the first top block 16. A movable frame 17 is slidably connected to the middle of the rotating module 11. The first top block 16 is squeezed and matched with the movable frame 17. Four second top blocks 18 equidistantly distributed around the circumference are fixedly connected to the top of the movable frame 17. The second top block 18 is made of glass wool. The second top block 18 is slidably connected to the rotating module 11. The second top block 18 is in contact and matched with the porcelain insulator 12. A fixed component is provided on the second top block 18.

[0044] like Figure 1 As shown, a cover plate is slidably connected to the left front side of the chassis 1, and an observation window is opened in the middle of the cover plate.

[0045] like Figure 5 As shown, both left and right parts of the rear side of the movable top frame 14 are provided with inclined surfaces for squeezing the first top block 16 and making the first top block 16 move upward smoothly.

[0046] like Figure 6 and Figure 8 As shown, the fixed assembly includes a pressure frame 111, a rotating rod 112, a pull rope 113, a connecting block 114 and a rope winding drum 115. The rotating rod 112 is rotatably connected to the upper side of the second top block 18. The middle of the rotating rod 112 is fixedly connected to the pressure frame 111, and the pressure frame 111 is in contact with the porcelain insulator 12. Both ends of the rotating rod 112 are fixedly connected to the rope winding drum 115, and one end of the pull rope 113 is wound around the outside of the rope winding drum 115. The rotating module 11 is fixedly connected to four groups of connecting blocks 114 equidistantly distributed around the circumference, and each group includes two connecting blocks 114. The other end of the pull rope 113 is fixedly connected to the adjacent connecting block 114.

[0047] When the worker needs to inspect the porcelain insulator 12 for iron impurities, he can first slide the cover plate of the chassis 1 to the left to open it, then place the porcelain insulator 12 in the center of the rotating module 11, then slide the cover plate to the right to close it and start the electric slide rail 15, thereby driving the movable top frame 14 to move backward, and the movable top frame 14 moving backward will contact and squeeze the first top block 16, so that the first top block 16 moves upward and squeezes the movable frame 17, so that the movable frame 17, the second top block 18 and the porcelain insulator 12 move upward, and the porcelain insulator 12 will be separated from the rotating module 11 at this time, so as to prevent the porcelain insulator 12 from being damaged after being subsequently heated by microwaves. The heat is transferred to the rotating module 11 due to heat conduction, and affects the collected data of the infrared thermal imaging acquisition module 13, and the upward movement of the second top block 18 will also drive the pressure frame 111, the rotating rod 112 and the rope winding drum 115 to move upward. At this time, the pull rope 113 will gradually be straightened and drive the pressure frame 111, the rotating rod 112 and the rope winding drum 115 to rotate upward, and the upward rotation of the pressure frame 111 will contact the porcelain insulator 12 and limit it to prevent the porcelain insulator 12 from deviating on the second top block 18. After that, the rotating module 11, the microwave generating module 1101 and the infrared thermal imaging acquisition module 13 can be started through the joint control module 1301.

After the detection is completed, the first The rotating module 11, the microwave generating module 1101 and the infrared thermal imaging acquisition module 13 are turned off through the joint control module 1301, and then the movable top frame 14 is driven forward to be reset through the electric slide rail 15. At this time, the first top block 16, the second top block 18 and the porcelain insulator 12 and other components will move downward and reset under the action of their own gravity, and the pull rope 113 will be loosened immediately. Finally, the porcelain insulator 12 can be removed from the rotating module 11. Removing the porcelain insulator 12 from the rotating module 11 will also squeeze the pressing frame 111, so that the pressing frame 111, the rotating rod 112 and the rope winding drum 115 rotate in the opposite direction to reset and rewind the pull rope 113.

[0048] Example 2

[0049] On the basis of Example 1, Fig. 9 and Fig.10As shown, a cleaning mechanism is also included, which is arranged on the chassis 1. The cleaning mechanism includes a hollow brush holder 2, a support frame 21, a guide frame 22, a swing rod 23 and a push frame 24. The two guide frames 22 are respectively fixed to the left and right parts of the rear side of the chassis 1. The guide frame 22 is slidably connected to the support frame 21 on one side close to the porcelain insulator 12. The top of the support frame 21 is fixedly connected to the hollow brush holder 2. The hollow brush holder 2 is in contact with the porcelain insulator 12. The left and right parts of the rear side of the movable top frame 14 are fixedly connected to the push frame 24. The top of the rear side of the push frame 24 is rotatably connected to the swing rod 23, and the swing rod 23 is rotatably connected to the adjacent support frame 21.

[0050] When the porcelain insulator 12 is placed in the center of the rotating module 11, the rotating module 11 can also be started through the joint control module 1301. The rotating module 11 will drive the porcelain insulator 12 and other components to rotate. At this time, the hollow brush holder 2 will contact the porcelain insulator 12 and clean up impurities such as dust and debris on its outer surface to prevent impurities such as metal or graphite from absorbing microwaves and generating heat, thereby affecting the subsequent data acquisition of the infrared thermal imaging acquisition module 13. When the electric slide rail 15 drives the movable top frame 14 to move backward, the push frame 24 will also move backward, and the swing rod 23 will immediately rotate and make the support frame 21 and the hollow brush holder 2 move along the guide frame 22 away from the porcelain insulator 12 to prevent the hollow brush holder 2 from blocking the subsequent upward movement of the porcelain insulator 12. When the electric slide rail 15 drives the movable top frame 14 and the push frame 24 to move forward and reset, the swing rod 23 immediately rotates in the opposite direction and makes the support frame 21 and the hollow brush holder 2 move along the guide frame 22 toward the porcelain insulator 12 and reset.

[0051] like Fig.11 As shown, a cleaning mechanism is also included, which is arranged in the chassis 1. The cleaning mechanism includes a suction pump 3, a guide pipe 31, a connecting pipe 32 and an air suction disc 33. The suction pump 3 is fixedly connected to the top of the chassis 1.

The suction disc 33 is connected and fixedly connected to the hollow brush holder 2 with a connecting pipe 32. The suction disc 33 is in contact with the porcelain insulator 12.

[0052] When the porcelain insulator 12 is placed in the center of the rotating module 11 and the outer surface of the porcelain insulator 12 is cleaned through the hollow brush holder 2, the suction disk 33 can also be placed on the top of the porcelain insulator 12 and the suction pump 3 can be started. At this time, the suction disk 33 will suck impurities such as dust and debris on the inner wall of the porcelain insulator 12 into the storage box of the suction pump 3 through the guide tube 31, so as to clean the impurities on the inner wall of the porcelain insulator 12 and prevent impurities made of materials such as metal or graphite from absorbing microwaves and generating heat, thereby affecting the subsequent data collection of the infrared thermal imaging acquisition module 13. During this period, the suction disk 33 will also suck impurities on the outer surface of the porcelain insulator 12 into the storage box of the suction pump 3 through the connecting tube 32 and the hollow brush holder 2, thereby improving the cleaning effect of the hollow brush holder 2. After cleaning, the suction pump 3 can be turned off.

[0053] like Figure 12-Figure 15 As shown, it also includes a supporting mechanism, which is arranged on the chassis 1, and the supporting mechanism includes an air cylinder 4, a first air guide pipe 41, an elastic block 42, a connector 43, a second air guide pipe 44 and an expansion block 45, wherein the connector 43 is hollow inside and is divided into an upper connecting shell and a lower connecting shell, and the upper connecting shell is rotatably connected to the lower connecting shell, and the two air cylinders 4 are respectively fixed to the left and right parts of the front side of the chassis 1, and the piston rod of the air cylinder 4 is fixed to the movable top frame 14, and the lower connecting shell of the connector 43 is fixed to the bottom of the inner wall of the chassis 1, and the air cylinder 4 is fixed to the bottom of the inner wall of the chassis 1. The lower connecting shell of the connector 43 is connected and fixedly connected with the first air duct 41, the upper connecting shell of the connector 43 is fixedly connected to the bottom of the rotating module 11, four elastic blocks 42 equidistantly distributed around the circumference are fixedly connected to the middle of the rotating module 11, the elastic blocks 42 are in contact and fit with the moving frame 17, four expansion blocks 45 equidistantly distributed around the circumference are fixedly connected to the middle of the rotating module 11, the expansion blocks 45 are squeezed and fit with adjacent elastic blocks 42, and the second air duct 44 is connected and fixedly connected to the upper connecting shell of the connector 43.

[0054] like Fig.13 As shown, a cross bar is fixedly connected to the top of the elastic block 42 for supporting the movable frame 17 .

[0055] When the electric slide rail 15 drives the movable top frame 14 to move backward and makes the movable frame 17, the second top block 18 and the porcelain insulator 12 move upward, the piston rod of the gas cylinder 4 will also move backward with the movable top frame 14, so that the gas of the gas cylinder 4 is gradually injected into the connector 43 through the first air guide pipe 41, and then input into the second air guide pipe 44 from the connector 43 and finally injected into the expansion block 45, and the expansion block 45 will gradually expand and squeeze the elastic block 42, and the upper part of the elastic block 42 will be deformed and move towards the movable frame 17. When the movable frame 17, the second top block 18 and the porcelain insulator 12 move upward to the top under the action of the movable top frame 14, the expansion block 45 will also expand to the maximum, so that the upper part of the elastic block 42 is deformed and moves to the bottom of the movable frame 17 and contacts with it, so that the elastic block 42 can be used to The elastic block 42 supports the moving frame 17, the second top block 18, the porcelain insulator 12 and other components to prevent the porcelain insulator 12 and other components from being offset and tilted when the rotating module 11 drives the porcelain insulator 12 and other components to rotate, thereby causing deviations in the position information of impurity detection. When the electric slide rail 15 drives the piston rod of the moving top frame 14 and the air cylinder 4 to move forward and reset, the gas in the expansion block 45 will be gradually sucked back into the air cylinder 4 through the second air duct 44, the connector 43 and the first air duct 41, and the expansion block 45 will then deform and shrink, and the elastic block 42 will also deform and return to its original state under the action of its own elasticity. At this time, the elastic block 42 does not support the moving frame 17, and the moving frame 17, the second top block 18, the porcelain insulator 12 and other components can move downward and reset under the action of their own gravity.

[0056] like Fig.16 As shown, a protective mechanism is also included, which is arranged on the chassis 1. The protective mechanism includes a protective lead shell 5 and a lead film 51. The two protective lead shells 5 are respectively fixed to the left and right parts of the front side of the chassis 1. The electric slide rail 15 is located in the protective lead shell 5. The protective lead shell 5 is slidably connected to the movable top frame 14. Front and rear two layers of lead film 51 are fixed between the movable top frame 14 and the protective lead shell 5.

[0057] Since microwaves may interfere with the normal operation of electronic components, a protective lead shell 5 and a lead film 51 are provided on the outside of the electric slide rail 15, wherein a layer of metal lead inside the protective lead shell 5 and the lead film 51 can effectively block and isolate microwaves, thereby preventing microwaves from affecting the operation of the electric slide rail 15. When the electric slide rail 15 drives the movable top frame 14 to move forward and backward, the corresponding lead films 51 on the front and rear sides will shrink and expand respectively, and always block the opening of the protective lead shell 5 on the side close to the movable top frame 14, thereby ensuring a good isolation effect against microwaves.
