DETAILED DESCRIPTION
[0020] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific embodiments.
[0021] As Figures 1 to 17 shown, the present application includes the following embodiments: Embodiment 1: An adjustable power detection device, comprising a detection table 1 and two vertical plates 2 on the upper surface of the detection table 1; two main wheels 31 are rotatably connected to each other on one side of the two vertical plates 2; two front and rear main wheels 31 are drivingly connected to an insulating belt 3; the outer surface of the insulating belt 3 is uniformly provided with a conductive sheet 32 along the transmission direction; the conductive sheet 32 is electrically conductive with the inner edge of the insulating belt 3 through a main conductive rod 33 inside the insulating belt 3; a conductive assembly 4 is arranged at the middle position of the inner side of the insulating belt 3; the conductive assembly 4 is in contact with the inner edge of the middle position of the insulating belt 3; two detection instruments 5 are fixedly connected to each other on the side of the two vertical plates 2 away from each other; the two detection instruments 5 are electrically connected; the conductive assembly 4 is electrically connected with the detection instrument 5; the lower surface of the detection table 1 is threadedly connected with a supporting leg 11; the two overlapping test pieces on the insulating belt 3 move forward under their own weight and pass through the conductive assembly 4.
[0022] After placing the detection device around the lightning arrester to be detected, the supporting leg 11 is screwed to change the slope of the upper surface of the detection table 1, the greater the slope of the upper surface of the detection table 1, the slower the transmission speed of the lightning arrester along the insulating belt 3, which means the longer the detection time, the detection instrument 5 can be selectively connected in series with a voltage doubler, which can be adjusted according to actual needs, after the supporting leg 11 is adjusted, the lightning arrester is loaded on the upper position of the two insulating belts 3 respectively, the insulating belt 3 is in the shape of an annular belt, the end of the lightning arrester is clamped between the two conductive sheets 32 on the outer wall of the insulating belt 3, the two conductive sheets 32 have a certain elasticity, which realizes clamping of the end of the lightning arrester, then the lightning arrester is loosened, because the supporting leg 11 supports the rear end of the detection table 1, the height of the rear end of the detection table 1 is higher than that of the front end, so that the height of the rear end of the insulating belt 3 is higher than that of the front end, the end of the lightning arrester clamped on the insulating belt 3 has a component force moving forward, under the action of the component force, the lightning arrester drives the insulating belt 3 to transmit, the upper half of the insulating belt 3 transmits forward, when the lightning arrester moves to the conductive assembly 4, the end of the lightning arrester connects the conductive assembly 4 on the inner edge of the insulating belt 3 through the conductive sheet 32 and the main conductive rod 33, the conductive assembly 4 is connected with the corresponding detection instrument 5, thus forming a closed loop.
[0023] During the formation of the loop by the lightning arrester, the detection instrument 5 detects the power of the lightning arrester, and judges whether the quality of the lightning arrester meets the requirements according to the detection value, after the lightning arrester moves away from above the conductive assembly 4, the conductive assembly 4 is disconnected with the corresponding conductive sheet 32, after the next lightning arrester moves to above the conductive assembly 4, the new lightning arrester completes the connection of the power and detects, the lightning arrester that has completed the power detection is unloaded from the main wheel 31 at the front position, and the process is repeated; the embodiment does not need to clamp and loosen the clamps, has higher detection efficiency, can realize continuous detection, and the detection and loading are carried out separately and do not affect each other; The lightning arrester end is overlapped on two insulating bands 3 and contacts with the conductive sheet 32 on the insulating band 3, so that the conductive sheet 32 is connected to the detector 5 and detected during passing through the conductive assembly 4, and the lightning arrester is disconnected after moving away from the conductive assembly 4, and the detection efficiency and convenience are improved by abandoning the traditional detection mode by clamps.
[0024] In the embodiment, the conductive assembly 4 comprises a secondary shaft 41, a secondary wheel 42, a conductive band 43 and a secondary conductive rod 44; the secondary shaft 41 is rotationally connected with the corresponding vertical plate 2 and electrically connected with the corresponding detector 5; the secondary wheel 42 is fixedly connected to the outer wall of the secondary shaft 41; the conductive band 43 is drivingly connected to the front and rear secondary wheels 42; the outer edge of the conductive band 43 is in contact with the inner edge of the middle section of the insulating band 3; the main hole 34 is arranged through the inner and outer walls of the insulating band 3; the main conductive rod 33 is fixedly connected to the outer end of the main hole 34; and the secondary conductive rod 44 is arranged on the outer wall of the conductive band 43 and can be inserted into the inner end of the main hole 34.
[0025] In the embodiment, the conductive band 43 is provided with a secondary hole 45; the secondary conductive rod 44 is movably connected in the secondary hole 45; and the secondary conductive rod 44 is connected with the hole bottom of the secondary hole 45 through a secondary spring 46.
[0026] The inner wall of the insulating band 3 and the outer wall of the main wheel 31 are roughened to avoid slipping; similarly, the inner wall of the conductive band 43 and the outer wall of the secondary wheel 42 are roughened to avoid slipping; during the transmission process of the insulating band 3 on the outer wall of the main wheel 31, the main hole 34 on the insulating band 3 moves with the transmission of the insulating band 3, the outer end of the main hole 34 is close to the outer edge of the insulating band 3, the inner end of the main hole 34 is close to the inner edge of the insulating band 3, and the secondary conductive rod 44 enters the main hole 34 and contacts with the main conductive rod 33 in the main hole 34 when the main hole 34 is aligned with the secondary conductive rod 44 on the conductive band 43, so that the end of the lightning arrester is connected to the corresponding detector 5 through the conductive sheet 32, the main conductive rod 33, the secondary conductive rod 44, the conductive band 43, the secondary wheel 42 and the secondary shaft 41, and in short, the lightning arrester is connected after the main conductive rod 33 contacts with the secondary conductive rod 44, and the conductive band 43 is driven with the transmission of the insulating band 3 because the secondary conductive rod 44 is inserted into the main hole 34, so that the contact between the main conductive rod 33 and the secondary conductive rod 44 is more stable, and the abrasion and poor contact caused by sliding contact are avoided, so that the lightning arrester detection is more stable.
[0027] Further, since the auxiliary conducting rod 44 is elastically movably connected in the auxiliary hole 45, the auxiliary conducting rod 44 is pressed to overcome the auxiliary spring 46 to retract in the auxiliary hole 45 before the auxiliary hole 45 is aligned with the main hole 34, and the auxiliary conducting rod 44 in the auxiliary hole 45 is inserted into the main hole 34 under the elastic force of the auxiliary spring 46 after the auxiliary hole 45 is aligned with the main hole 34, and the auxiliary conducting rod 44 contacts the main conducting rod 33 in the main hole 34, and since the inner end of the main hole 34 can slightly deform, the auxiliary conducting rod 44 can be pulled out of the main hole 34, ensuring stable transmission of the insulating belt 3 and the conducting belt 43. Since the auxiliary conducting rod 44 is elastically movably connected to the outer wall of the conducting belt 43, the auxiliary conducting rod 44 cannot lift the insulating belt 3 outward before the auxiliary hole 45 is not completely aligned with the main hole 34, which ensures that the insulating belt 3 remains flat under the contact and lifting of the conducting belt 43, avoiding the situation that the lightning arrester end falls off the outer wall of the insulating belt 3, making the transmission detection of the lightning arrester on the insulating belt 3 more stable.
[0028] In this embodiment, the detection table 1 is rotatably connected with the screw 6 through the slot hole 14; the screw 6 is provided with the insertion slot 66 on the outer wall near the end; the slot hole 14 is provided with the threaded hole 15 penetrating upward; and the first bolt 16 is threadedly connected in the threaded hole 15.
[0029] In this embodiment, the detection table 1 is rotatably connected with the screw 6 through the slot hole 14; the screw 6 is provided with the insertion slot 66 on the outer wall near the end; the slot hole 14 is provided with the threaded hole 15 penetrating upward; and the first bolt 16 is threadedly connected in the threaded hole 15.
[0030] Before the lightning arrester is detected by the detection device, pull the pull ring 65 to drive the pull rope 64 to move in the rope groove, and the inner end of the pull rope 64 will be unwound from the thread wheel 63, thereby driving the thread wheel 63 to rotate, and the screw rod 6 will rotate during the rotation of the thread wheel 63, and the screw rod 6 is oppositely threaded at both ends, so that the screw rod 6 will drive the two adjusting blocks 61 to slide along the slot of the adjusting groove 12 during the rotation of the screw rod 6, and the two adjusting blocks 61 need to overcome the elastic force of the first spring 62 during the mutual moving away of the two adjusting blocks 61, and the two adjusting blocks 61 will drive the vertical plates 2 connected thereto to move away from each other during the mutual moving away of the two adjusting blocks 61, so that the two vertical plates 2 move away from each other, and the two vertical plates 2 will drive the two insulating bands 3 to move away from each other, and after the distance between the two vertical plates 2 is adapted to the length of the lightning arrester, the lightning arrester is placed between the two vertical plates 2, the end of the lightning arrester is placed on the corresponding insulating band 3, and the lightning arrester is loosened, so that the lightning arrester is self-detected; after the detection is completed, the pull ring 65 is loosened, and the first spring 62 will push the adjusting block 61 to reset, and the two adjusting blocks 61 will slide along the slot of the adjusting groove 12 and move close to each other, and the two adjusting blocks 61 will drive the vertical plates 2 connected thereto to move close to each other, and the vertical plates 2 will drive the insulating bands 3 connected thereto to move, so that the main wheels 31 on the two vertical plates 2 abut against each other, and the distance between the two vertical plates 2 is minimized, so that the insulating bands 3 and the conductive sheets 32 between the two vertical plates 2 are protected during transportation; The flexible adjusting block 61 is suitable for lightning arrester detection of different specifications, has a wide application range, and if the length specifications of the lightning arrester to be detected are the same, the first screw 16 can also be selectively screwed, and after the first screw 16 is screwed, the first screw 16 will move along the threaded hole 15, the end of the first screw 16 will enter the corresponding insertion slot 66, the screw rod 6 is locked, the screw rod 6 cannot rotate with the pushing of the adjusting block 61, and the distance between the two vertical plates 2 is constant, so as to meet the detection requirements. In the embodiment, the pull rope 64 is pulled to drive the screw rod 6 to rotate, and the first spring 62 is matched, so that the distance between the two vertical plates 2 is adjustable, and the detection device is more convenient for lightning arrester power detection of different specifications and has a wide detection range.
[0031] In embodiment 4, a sliding groove 67 is arranged on the outer wall of the middle section of the screw rod 6 along the axial direction; a sliding block 68 is slidably connected in the sliding groove 67; the thread wheel 63 is sleeved on the outer wall of the middle section of the screw rod 6 and is fixedly connected with the sliding block 68; the slot of the middle section of the adjusting groove 12 is shielded; an annular corrugated groove 17 is arranged on the inner wall of the adjusting groove 12; a corrugated block 18 is movably connected in the corrugated groove 17; and the corrugated block 18 is fixedly connected with the outer wall of the thread wheel 63.
[0032] In the process of pulling the pull ring 65 to drive the pull rope 64 to be unwound from the thread wheel 63, the thread wheel 63 will drive the screw rod 6 to rotate, and the thread wheel 63 will rotate in the adjusting groove 12, and the thread wheel 63 will drive the corrugated block 18 to move in the corrugated groove 17 during rotation. The corrugated block 18 is in the shape of a circle, and during the movement of the corrugated block 18 along the corrugated groove 17, the thread wheel 63 will fluctuate back and forth in the axial direction of the screw rod 6, so that the thread wheel 63 will be offset from the rope hole 13 during rotation. In this way, under the condition that the pull ring 65 is loosened, the first spring 62 will push the respective adjusting block 61 to move, and the two adjusting blocks 61 will move close to each other to make the screw rod 6 rotate, and the rotation of the screw rod 6 will drive the thread wheel 63 to rotate, and the thread wheel 63 will wind the pull rope 64 during rotation. Since the thread wheel 63 will fluctuate back and forth in the axial direction of the screw rod 6 during rotation, the pull rope 64 will be wound on the thread wheel 63 in a staggered manner, avoiding the accumulation of the pull rope 64 on the thread wheel 63, which affects the rotation of the thread wheel 63 in the adjusting groove 12, and improving the smoothness of the distance adjustment between the two vertical plates 2.
[0033] In the embodiment, the synchronous groove 19 is arranged in the front position inside the detection table 1 along the left-right direction; the synchronous groove 19 penetrates upward; the synchronous gear 7 is rotationally connected in the synchronous groove 19; the gear groove 21 is arranged in the vertical plate 2 and penetrates downward; the main wheel 31 is rotationally connected with the vertical plate 2 through the main shaft 35; the driving gear 36 is fixedly connected to the outer wall of the main shaft 35; the driven gear 37 is rotationally connected in the gear groove 21 below the driving gear 36; the driven gear 37 is engaged with the driving gear 36 and the synchronous gear 7.
[0034] Due to the protruding umbrella skirt structure on the outer wall of the lightning arrester, the main wheels 31 on the two vertical plates 2 cannot be connected through the connecting shafts that move close to each other. In order to ensure the consistency of the transmission of the two insulating belts 3 on the vertical plates 2, the synchronous groove 19 with the synchronous gear 7 is arranged to penetrate upward in the detection table 1. In this way, when the vertical plate 2 moves in the left-right direction, the vertical plate 2 will drive the driving gear 36 and the driven gear 37 inside to move synchronously in the left-right direction. The driven gear 37 keeps the state of being engaged with the synchronous gear 7 and moves axially with the synchronous gear 7. After the movement of the vertical plate 2 is completed, the power detection of the lightning arrester is started. After the lightning arrester is placed on the insulating belt 3, the insulating belt 3 is driven, and the main wheel 31 rotates with the transmission of the insulating belt 3. The main wheel 31 drives the main shaft 35 and the driving gear 36 to rotate. The driving gear 36 is engaged with the synchronous gear 7 through the driven gear 37. Therefore, the two insulating belts 3 are synchronously driven to avoid the inconsistency of the transmission of the two insulating belts 3, which causes the lightning arrester to tilt and fall off, and improve the stability during the power detection of the lightning arrester. In this embodiment, the two insulating belts 3 on the vertical plates 2 are connected together through the synchronous gear 7, so as to on the one hand, the detection gap between the two vertical plates 2 is emptied, and on the other hand, the lightning arrester detection process is more stable.
[0035] Example 6: An arc-shaped protective plate 8 is provided around the front end of the insulating strip 3; a corresponding protective groove 22 is provided on the vertical plate 2; the protective plate 8 and the protective groove 22 are slidably and sealingly connected; an L-shaped driving groove 23 is provided on the side of the two vertical plates 2 close to each other; a driving block 9 is slidably and sealingly connected to the driving groove 23; a driving plate 91 is fixedly connected to the driving block 9 facing outward; the driving plate 91 is located directly below the front end of the corresponding insulating strip 3; the bottom of the protective groove 22 and the upper end of the driving groove 23 are connected through a liquid hole 24; the upper end of the driving groove 23 and the driving block 9 are connected by a tension spring 25.
[0036] In this embodiment, the two drive plates 91 are provided with shrinkage grooves 92 on one side close to each other; a shrinkage plate 93 is slidably connected in the shrinkage groove 92; the shrinkage plate 93 is connected to the bottom of the shrinkage groove 92 by a second spring 94.
[0037] As the surge arrester moves along the insulating strip 3 to its forward position, it enters the inner side of the protective plate 8. Due to the protection provided by the protective plate 8, the surge arrester will not fall directly from the upper part of the insulating strip 3, thus achieving speed-limiting protection. The awning portion of the surge arrester's outer wall gradually moves downwards and contacts the drive plate 91. The pressure on the drive plate 91 causes the drive block 9 to move downwards along the drive groove 23, overcoming the tension of the tension spring 25. During the downward movement of the drive block 9, the space within the drive groove 23... As the pressure increases, a negative pressure is formed. Under the action of the negative pressure, the liquid medium in the protective groove 22 flows into the driving groove 23 along the liquid hole 24. This causes the protective plate 8 to retract into the protective groove 22 until the driving plate 91 is pressed and contacts the upper surface of the test table 1. Then, the protective plate 8 will move away from the front end of the insulating strip 3, releasing the restriction on the end of the surge arrester. The driving plate 91 moves down to buffer the surge arrester. The restriction of the protective plate 8 reduces the unloading speed of the surge arrester. Then, the surge arrester will roll forward and be unloaded along the driving plate 91 and the upper surface of the test table 1. After the surge arrester disengages from the drive plate 91, the tension spring 25 pulls the drive block 9 upward, which in turn drives the drive plate 91 upward. During the upward movement of the drive block 9, the liquid medium in the squeezed drive groove 23 flows into the protective groove 22 along the liquid hole 24, causing the protective plate 8 to extend out of the protective groove 22 again and block and limit the front end of the insulating strip 3. Furthermore, a shrink plate 93 is set on one side of the two drive plates 91 that is close to each other. The shrink plate 93 retracts into the shrink groove 92 against the second spring 94 during the process of the two vertical plates 2 approaching each other, so as to avoid the movement of the vertical plate 2 and meet the adjustment requirements of the vertical plate 2.
