Description

Technical Field

[0001] The present invention relates to the technical field of accessory detection, and in particular to an accessory quality inspection device for assembling communication equipment. Background Art

[0002] Zinc oxide arrester is an arrester with good protection performance. It can effectively protect communication equipment. It uses the good nonlinear volt-ampere characteristics of zinc oxide to make the current flowing through the arrester extremely small (microampere or milliampere level) at normal working voltage. When overvoltage acts, the resistance drops sharply, discharging the overvoltage energy to achieve the protection effect.

[0003] If the zinc oxide arrester is assembled without discharging moisture in time, it is easy to cause a certain amount of humidity to remain inside the zinc oxide arrester. Since the insulating material inside the zinc oxide arrester is hygroscopic, the insulating material inside the zinc oxide arrester will gradually absorb moisture, causing the insulating material to become damp;

[0004] In addition, the outer jacket of the zinc oxide arrester is made of ceramic material (refer to the attached drawing of the specification Figure 2 The component placed on the top of the rotating inner core 2 in the middle), during the storage of the zinc oxide lightning arrester, due to the aging or respiration of the material of the outer porcelain sleeve itself, cracks may appear in the outer porcelain sleeve, and moisture may enter the interior of the zinc oxide lightning arrester through the cracks, causing the zinc oxide lightning arrester to become damp, and after the zinc oxide lightning arrester becomes damp, its insulation resistance will significantly decrease, so it is necessary to detect whether the zinc oxide lightning arrester is damp by measuring the insulation resistance of the zinc oxide lightning arrester. The existing detection method mainly connects the zinc oxide lightning arrester to be tested with a megohmmeter to realize its resistance detection function, but this method is inefficient, and it is necessary to connect and disconnect the zinc oxide lightning arresters to be tested one by one, and after detecting that the lightning arrester to be tested is damp, it is impossible to accurately determine which of the above reasons caused the dampness, which is not conducive to the fault analysis of the zinc oxide lightning arrester, and therefore a communication equipment assembly accessories quality inspection device is proposed to solve the above problems.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example, see Figures 1 to 8 A quality inspection device for accessories for assembling communication equipment comprises a support cylinder 1 installed on the ground through a support member and a rotating inner core 2 rotatably arranged inside the support cylinder 1, a feeding port is provided at the top of the support cylinder 1, a feeding pipe 9 is fixedly connected to the feeding port, three discharge ports are provided at the bottom of the support cylinder 1, a crack recovery box 4, a moisture recovery box 24 and a good product recovery box 25 are arranged at the three discharge ports in a clockwise order, further, a silicone tube 5 is provided inside the crack recovery box 4, the moisture recovery box 24 and the good product recovery box 25 for buffering the falling of the zinc oxide lightning arrester.

[0034] Reference Figures 7 and 8The surface of the supporting cylinder 1 is fixedly connected with a megohmmeter 3, and the side wall of the supporting cylinder 1 is provided with a power connection component, which includes an arc-shaped guide plate 6 fixedly connected with the side wall of the supporting cylinder 1, and an arc-shaped through-hole 601 is opened on the side wall of the arc-shaped guide plate 6. A pair of half-moon support plates 12 are slidably provided on the inner wall of the arc-shaped guide plate 6, and a power connection slider 14 is slidably provided on the inner side of the half-moon support plate 12. An electrode block 17 is slidably provided on the inner wall of the power connection slider 14, and one end of the electrode block 17 is fixedly connected with an electrode rod 16, and one end of the electrode rod 16 passes through the arc-shaped through-hole 601, and one end of the electrode rod 16 is connected to the megohmmeter through a wire. The ohmmeter 3 is connected (the megohmmeter 3 is connected to the external controller); further, an inclined surface is provided at one end of the electrode block 17, a reset spring 15 is sleeved on the electrode rod 16, one end of the reset spring 15 is fixedly connected to the electrode block 17, the other end of the reset spring 15 is fixedly connected to the inner wall of the power-connecting slider 14, the semi-lunar support plate 12 is fixedly connected to the inner wall of the arc-shaped guide rail plate 6 through the bending spring 13, there is a mutually repulsive magnetic force between the power-connecting slider 14 and the side wall of the arc-shaped guide rail plate 6 on which the arc-shaped through-hole 601 is opened, and the side wall of the arc-shaped guide rail plate 6 is fixedly connected with a magnetic attraction block 11 which is magnetically attracted to the electrode block 17.

[0035] It should be noted that: when the zinc oxide lightning arrester to be tested falls on the inner side of the conveying trough 201, the rotating inner core 2 drives the zinc oxide lightning arrester to be tested to make a circular motion. When the two ends of the zinc oxide lightning arrester to be tested contact the inclined surface of the electrode block 17, the electrode block 17 will be squeezed, and the electrode block 17 drives the electrode rod 16 to move and compresses the reset spring 15. Under the action of the reset spring 15, the electrode block 17 is in close contact with the two ends of the zinc oxide lightning arrester to be tested (the "L" terminal lead and the "E" terminal lead of the megohmmeter 3 are electrically connected to the electrode rods 16 on both sides, respectively, the electrode block 17 on one side is in contact with the high-voltage terminal of the zinc oxide lightning arrester to be tested, and the electrode block 17 on the other side is connected to the grounding terminal of the zinc oxide lightning arrester to be tested);

[0036] The zinc oxide lightning arrester to be tested drives the power connection slider 14 to slide inside the arc guide plate 6. During the sliding process, the megohmmeter 3 detects the insulation resistance of the zinc oxide lightning arrester to be tested, and transmits the detected value to the controller. If the detected insulation resistance value is not within the normal insulation resistance value range (for lightning arresters above 35kV, the voltage of the megohmmeter 3 is 5000V, and the insulation resistance is greater than 2500MΩ, which is normal; for lightning arresters below 35kV, the voltage of the megohmmeter 3 is 2500V, and the insulation resistance is greater than 1000MΩ, which is normal), it means that the zinc oxide lightning arrester to be tested is damp, and the controller controls the screening motor 10 at the damp recovery box 24 to work, so that the screening tooth plate 22 at this place moves to the inside of the retraction groove 102;

[0037] It should be noted that the time from the start of sliding of the power connection slider 14 to the end of sliding is 60 seconds, that is, the megohmmeter 3 can measure the resistance of the zinc oxide lightning arrester to be tested for 60 seconds;

[0038] When the power-connecting slider 14 slides to the magnetic block 11 (the bending spring 13 is in a compressed state during this process), the magnetic block 11 will magnetically attract the electrode block 17, thereby driving the power-connecting slider 14 to slide and separate from the two ends of the zinc oxide lightning arrester that has been tested. Under the elastic force of the bending spring 13, the power-connecting slider 14 is reset, and the zinc oxide lightning arrester to be tested continues to move with the rotating inner core 2 (the two ends of the zinc oxide lightning arrester to be tested can pass through the opening at the bottom end of the arc guide plate 6, see Figure 8 ).

[0039] There are multiple conveying grooves 201 distributed circumferentially on the surface of the rotating inner core 2, and multiple arc-shaped inner grooves 202 are linearly arranged at the inner bottom end of the conveying groove 201. A crack detection component for detecting cracks in the outer porcelain sleeve of the zinc oxide lightning arrester is arranged on the inner side of the arc-shaped inner groove 202. The crack detection component includes an arc-shaped slider 19 slidably arranged on the inner side of the arc-shaped inner groove 202, and multiple crack detection needles 21 are slidably arranged inside the arc-shaped slider 19; further, a rubber layer 101 is arranged inside the supporting cylinder 1, and when the zinc oxide lightning arrester to be tested makes a circular motion, the zinc oxide lightning arrester to be tested rotates under the action of the friction between the rubber layer 101 and the zinc oxide lightning arrester to be tested, and one end of the arc-shaped slider 19 is fixedly connected to the inner wall of the arc-shaped inner groove 202 through a positioning spring 20, and an internal pressure sensor 18 is installed on the inner wall of the arc-shaped inner groove 202.

[0040] It should be noted that: a plurality of telescopic slots are provided inside the arc-shaped slider 19, the surface crack detection needle 21 is slidably connected to the telescopic slot, and the surface crack detection needle 21 is fixedly connected to the inner wall of the telescopic slot due to the interference spring;

[0041] It should be noted that: when the zinc oxide lightning arrester to be tested falls on the inner side of the conveying trough 201, the outer porcelain sleeve on its surface contacts the crack detection needle 21, and there is an extrusion force between the outer porcelain sleeve and the crack detection needle 21; the zinc oxide lightning arrester to be tested rotates while making a circular motion with the rotating inner core 2. If there is a crack on the surface of the outer porcelain sleeve, the needle tip of the surface crack detection needle 21 will penetrate into the inside of the crack. At this time, the self-rotation of the zinc oxide lightning arrester will drive the crack detection needle 21 to rotate, thereby driving the arc slider 19 to slide and hit the internal pressure sensor 18. The internal pressure sensor 18 feeds back to the controller, and the controller controls the screening motor 10 at the crack recovery box 4 to work, so that the screening tooth plate 22 there moves to the inside of the retraction groove 102, so that the zinc oxide lightning arrester to be tested can be classified and collected according to the cause of moisture, which is convenient for fault analysis of the zinc oxide lightning arrester to be tested.

[0042] It is worth noting that: when the crack on the surface or arc surface of the outer porcelain sleeve is small, the needle tip of the surface crack detection needle 21 or the arc surface crack detection needle 27 penetrates shallowly. When the surface crack detection needle 21 or the arc surface crack detection needle 27 rotates to a state where it cannot rotate as the zinc oxide lightning arrester to be tested rotates, the needle tip is a cone structure, so that the surface crack detection needle 21 or the arc surface crack detection needle 27 can be separated from the crack.

[0043] When the cracks on the surface and the arc surface of the outer porcelain sleeve are large, the needle tips of the surface crack detection needle 21 and the arc surface crack detection needle 27 penetrate deeply. When the surface crack detection needle 21 or the arc surface crack detection needle 27 rotates to a state where it cannot rotate as the zinc oxide arrester to be tested rotates, the resistance given by the surface crack detection needle 21 or the arc surface crack detection needle 27 to the zinc oxide arrester to be tested is greater than the friction between the zinc oxide arrester to be tested and the rubber layer 101, so that the zinc oxide arrester to be tested cannot continue to rotate. The above two situations can realize the function of detecting cracks in the outer porcelain sleeve of the zinc oxide arrester to be tested.

[0044] The inner wall of the conveying groove 201 is linearly arranged with a plurality of inclined slide grooves, a surface detection block 26 is slidably arranged inside the inclined slide groove, a plurality of sliding cavities are opened inside the surface detection block 26, a pair of arc surface crack detection needles 27 are slidably arranged inside the sliding cavity, and an elastic cotton column is fixedly connected between the arc surface crack detection needles 27;

[0045] A cambered surface pressure sensor 29 is installed on the inner wall of the inclined slide groove, and the surface detection block 26 is connected to the cambered surface pressure sensor 29 via a connecting spring 28 .

[0046] It is worth noting that the arc surface pressure sensor 29 and the internal pressure sensor 18 establish an information transmission connection with the controller.

[0047] It should be noted that: when the zinc oxide lightning arrester to be tested is placed on the inner side of the conveying trough, the surface detection block 26 is located between the arc-shaped surfaces of the outer porcelain sleeve. At this time, the arc-shaped surface of the outer porcelain sleeve will squeeze the arc-shaped crack detection needle 27. When there is a crack on the arc-shaped surface of the outer porcelain sleeve, the needle tip of the arc-shaped crack detection needle 27 will penetrate into the inner side of the crack. The self-rotation force of the zinc oxide lightning arrester to be tested will move the arc-shaped crack detection needle 27, thereby driving the surface detection block 26 to slide on the inner side of the inclined slide groove, thereby squeezing the connecting spring 28. At this time, the arc-shaped pressure sensor 29 senses the pressure and feeds back to the controller. The controller controls the screening motor 10 at the crack recovery box 4 to work, so that the screening tooth plate 22 moves to the inner side of the retraction groove.

[0048] Furthermore, a reduction gear 7 is fixedly connected at the center of one end of the rotating inner core 2 , a servo motor 8 is installed on the side wall of the supporting cylinder 1 through a mounting frame, and a driving gear meshing with the reduction gear 7 is fixedly connected to the output end of the servo motor 8 .

[0049] It should be noted that the servo motor 8 drives the reduction gear 7 to rotate slowly through the driving gear, thereby driving the rotating inner core 2 to rotate slowly.

[0050] Furthermore, a retraction groove 102 is provided on the inner wall of the discharge port, a screening tooth plate 22 is slidably provided on the inner side of the retraction groove 102, a connecting port is provided on the side wall of the retraction groove 102, a screening motor 10 is installed on the side wall of the supporting cylinder 1, and an opening and closing control gear 23 meshing with the screening tooth plate 22 is fixedly connected to the output end of the screening motor 10.

[0051] It should be noted that: when the zinc oxide lightning arrester to be tested is not damp, the controller controls the screening motor 10 at the good product recovery box 25 to work, so that the screening tooth plate 22 moves to the inside of the retraction groove 102, and when the rotating inner core 2 carries the good zinc oxide lightning arrester and rotates to the good product recovery box 25, the good zinc oxide lightning arrester will automatically fall on the inside of the good product recovery box 25.

[0052] The present invention stacks the zinc oxide lightning arresters to be tested one by one from bottom to top on the inner side of the feeding tube 9, turns on the servo motor 8, and drives the reduction gear 7 to rotate slowly through the driving gear, thereby driving the rotating inner core 2 to rotate slowly. When the conveying groove 201 on the surface of the rotating inner core 2 rotates to the bottom of the feeding tube 9, the zinc oxide lightning arrester to be tested automatically falls on the inner side of the conveying groove 201. At this time, the surface crack detection needle 21 contacts the outer porcelain sleeve of the zinc oxide lightning arrester to be tested (there is an extrusion force between the two). When the zinc oxide lightning arrester to be tested makes a circular motion with the rotating inner core 2, the friction between the rubber layer 101 and the zinc oxide lightning arrester to be tested causes the zinc oxide lightning arrester to rotate.

[0053] At the same time, the two ends of the zinc oxide lightning arrester to be tested move to the inner side of the power connection slider 14 and contact the electrode block 17, and then the two ends of the zinc oxide lightning arrester to be tested drive the power connection slider 14 to slide counterclockwise along the arc guide plate 6. During this process, the megohmmeter 3 detects the insulation resistance of the zinc oxide lightning arrester to be tested, and at the same time, the crack detection component cooperates with the surface detection block 26 to detect whether there is a crack on its outer porcelain sleeve;

[0054] When the power-connecting slider 14 moves to the magnetic block 11 (the bending spring 13 is in a compressed state during this process), the magnetic block 11 will magnetically attract the electrode block 17, thereby driving the power-connecting slider 14 to slide and separate from the two ends of the zinc oxide lightning arrester to be tested. Under the elastic force of the bending spring 13, the power-connecting slider 14 is reset, and the zinc oxide lightning arrester to be tested continues to move with the rotating inner core 2 (the two ends of the zinc oxide lightning arrester to be tested can pass through the opening at the bottom end of the arc guide plate 6, see Figure 8), at this time, the megohmmeter 3 completes the insulation resistance detection of the zinc oxide lightning arrester to be tested, and transmits the detection result to the controller. If the detected insulation resistance value is not within the normal insulation resistance value range, the controller controls the screening motor 10 at the damp recovery box 24 to work, so that the screening tooth plate 22 moves to the inside of the retraction groove 102, and when the damp zinc oxide lightning arrester to be tested moves to the damp recovery box 24, it automatically falls inside the damp recovery box 24;

[0055] If there is a crack on the surface of the outer porcelain sleeve, the tip of the detection needle will penetrate into the inner side of the crack. At this time, the rotation of the zinc oxide arrester will drive the crack detection needle 21 to rotate around the zinc oxide arrester, thereby driving the arc slider 19 to slide and hit the internal pressure sensor 18. The internal pressure sensor 18 feeds back to the controller, and the controller controls the screening motor 10 at the crack recovery box 4 to work, so that the screening tooth plate 22 at this location moves to the inside of the retraction groove 102;

[0056] If there is a crack on the curved surface of the outer porcelain sleeve, the needle tip of the curved surface crack detection needle 27 will penetrate into the inner side of the crack, and the self-rotation force of the zinc oxide lightning arrester to be tested will move the curved surface crack detection needle 27, thereby driving the surface detection block 26 to slide on the inner side of the inclined slide groove, thereby squeezing the connecting spring 28. At this time, the curved surface pressure sensor 29 senses the pressure and feeds back to the controller. The controller controls the screening motor 10 at the crack recovery box 4 to work, so that the screening tooth plate 22 moves to the inner side of the retraction groove. When the zinc oxide lightning arrester with cracks on the surface of the outer porcelain sleeve rotates to the crack recovery box 4 with the rotating inner core 2, it will automatically fall on the inner side of the crack recovery box 4, so that the zinc oxide lightning arrester to be tested can be classified and collected according to the cause of moisture, which is convenient for fault analysis of the zinc oxide lightning arrester to be tested;

[0057] If the zinc oxide lightning arrester to be tested is not damp and there is no crack on the surface of the outer porcelain sleeve, the screening motor 10 at the crack recovery box 4 and the damp recovery box 24 will not work, and the good zinc oxide lightning arrester can move with the inner core to the good product recovery box 25 and fall into the good product recovery box 25 for recycling.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
