Description

Technical Field

[0002] With the rapid development of my country's economy, the use of electrical equipment has become more and more extensive. From household electricity to industrial production, from communication facilities to transportation, circuit systems are everywhere. However, electrical accidents caused by circuit failure, overload, short circuit, poor grounding and other problems occur from time to time, posing a serious threat to people's lives and property safety. Therefore, the importance of circuit safety detection devices has become increasingly prominent.

[0003] However, most of the existing circuit safety detection devices lack an automated circulating conveying mechanism, and workers may be required to hold and pull the cables for detection, which is not only inefficient, but also increases the risk of cable leakage posing a safety hazard to workers. At the same time, during the process of cable detection by workers, fatigue may cause cable leakage, thereby reducing the detection quality of the cable. At the same time, most of the existing circuit safety detection devices do not have the function of wiping and dusting the cable surface. Dust, dirt and other impurities on the cable surface will interfere with the detection results and reduce the detection accuracy. At the same time, it is also difficult to observe subtle scratches, cracks and other defects on the cable surface, affecting the comprehensive assessment of the cable condition and the detection accuracy.

[0021] In a second aspect, an embodiment of the present application further provides a circuit safety detection method, which uses the circuit safety detection device to perform circuit detection, including the following steps:

[0022] First, place the cable to be tested on the upper surface of the test table. At this time, the cable to be tested passes through the cleaning cylinder, and the initial head of the cable to be tested is placed in the middle of the second clamping plate.

[0023] At this time, the servo motor is started to rotate the first large transmission wheel and the second large transmission wheel. At this time, the first short rotating rod and the adjusting rod start to rotate under the action of the first belt. At this time, the first gear cylinder starts to mesh with the first gear plate under the action of the first short rotating rod, the first conversion gear and the second conversion gear. At the same time, the rotation directions of the first gear cylinders on both sides are inconsistent, thereby causing the first clamping plates to move away from each other, and at the same time, the first clamping plates are away from the cable to be detected;

[0024] At the same time, during the movement of the one-way slider, the second gear cylinder will mesh with the third adjusting gear teeth. At this time, under the action of the third gear cylinder, the first long rotating rod starts to drive the first gear to rotate. At this time, under the action of the second gear, the second short rotating rod, the first bevel gear and the second bevel gear, the second long rotating rod starts to drive the third gear to rotate.

[0025] When the third gear and the first adjusting tooth mesh with each other, the clamping frame drives the concave frame to move to the right;

[0026] At this time, the second adjusting tooth will mesh with the fourth gear cylinder during the process of moving to the right, and the fourth gear cylinder will drive the second gear plate to move to the left. At this time, both second clamping plates move toward the direction of the cable to be tested and fix the cable to be tested;

[0027] When the one-way slider moves to the rear end, the cable clamped by the second clamping plate will be driven to move backward synchronously. When the adjustment frame moves to the rearmost position, the servo motor will stop automatically.

[0028] At this point, the staff begins to test the cable to be tested by using a multimeter, test wires and measuring probes;

[0029] When a section of cable is detected, the servo motor is controlled in the opposite direction to move the adjustment frame to the original position. At this time, during the movement of the one-way slider and the adjustment frame, the second clamping plate begins to reset and no longer clamps the cable, and the first clamping plate begins to clamp the cable at the undetected position. Then, when the one-way slider returns to the original position, the servo motor is controlled to rotate in the initial rotation direction, so that the first clamping plate releases the cable to be detected, and the second clamping plate clamps the cable to be detected again and moves the cable.

[0030] During the movement of the one-way slider, the adjustment frame will drive the transfer rectangular table, the L-shaped transfer plate, the transmission bracket, the assembly slide frame and the cleaning cylinder to move synchronously toward the rear end;

[0031] During the movement of the transfer rectangular platform, the first gear and the fourth gear mesh with each other to rotate the third bevel gear, and the third long rotating rod drives the third large transmission wheel to rotate. At this time, the fourth short rotating rod starts to rotate under the action of the third small transmission wheel and the second belt;

[0032] At this time, the fifth short rotating rod starts to rotate under the action of the fourth large transmission wheel, the fourth small transmission wheel and the third belt, and at the same time, the fifth short rotating rod drives the fifth gear to mesh with the auxiliary gear, so that the installation sleeve drives the dust suppression sleeve to start rotating on the outer wall of the cable to be detected;

[0033] At the same time, when the cable to be detected moves to the rear end, the cleaning cylinder will rotate synchronously with the cable under the action of the adjusting frame. When the adjusting frame moves forward, the first clamping plate will fix the cable to be detected, so that the dust suppression sleeve will rotate and clean the outer wall of the cable to be detected during the rotation and forward movement.

[0034] The beneficial effects of the present application are as follows: when in use, the staff first places the cable to be detected on the upper end of the detection mechanism. At this time, the cable to be detected needs to be passed through the dust reduction and debris removal mechanism. At this time, the segmented positioning mechanism is started to transport the cable at the upper end of the detection mechanism. At the same time, the first clamping plate of the segmented positioning mechanism is in an open state, and the second clamping plate of the segmented clamping mechanism clamps the cable for transportation. When it is necessary to transport the next section of the cable to be detected, the servo motor is started in the opposite direction to return the segmented clamping mechanism to its original position, the first clamping plate begins to clamp the cable, and the second clamping plate is in an open state. At this time, the dust reduction and debris removal mechanism rotates and wipes the surface of the cable, wherein the servo motor is started to drive the adjustment frame to drive the cable to continuously circulate and transport. First, segmented detection is adopted to effectively improve the accuracy of cable detection. By alternately clamping the cable by the first clamping plate and the second clamping plate, it can be ensured that the cable avoids missed detection and multiple detection during the segmented detection process, thereby improving the efficiency of cable detection. Secondly, after the detection of one section of cable is completed and the one-way slider returns to its original position, the surface of the next section of the cable to be detected will be rotated and wiped by the dust reduction sleeve, thereby improving the cleanliness of the surface of the cable to be detected, effectively reducing the interference of dust, dirt and other impurities on the detection results, and improving the accuracy of detection. Thirdly, it is easier to observe subtle scratches, cracks and other defects on the surface of the cleaned cable, which helps to more comprehensively evaluate and detect the condition of the cable, and further improves the accuracy of cable detection. Fourthly, the cable can be circulated and transported, avoiding the staff from supporting and pulling the cable with their hands, reducing the safety hazards of cable leakage to the staff.

Specifically, when a section of cable is detected, the servo motor 202 is controlled in the opposite direction to move the adjustment frame 302 to the original position. At this time, during the movement of the one-way slider 301 and the adjustment frame 302, the second clamping plate 323 begins to reset and no longer clamps the cable, and the first clamping plate 209 begins to clamp the cable at the undetected position, and then when the one-way slider 301 returns to the original position, the servo motor 202 is controlled to rotate in the initial rotation direction.The first clamping plate 209 can release the cable to be detected, and the second clamping plate 323 can clamp the cable to be detected again to move the cable. During the movement of the one-way slider 301, the adjustment frame 302 can drive the transfer rectangular platform 401, the L-shaped transfer plate 405, the transmission bracket 409, the assembly slide frame 416 and the cleaning cylinder 417 to move synchronously to the rear end. During the movement of the transfer rectangular platform 401, the first gear 307 and the fourth gear 403 are engaged with each other to rotate the third bevel gear 404. At this time, the third long rotating rod 406 will drive the third large transmission wheel 408 to rotate. The fourth short rotating rod 410 starts to rotate under the action of the third small transmission wheel 411 and the second belt 412. At this time, the fifth short rotating rod 422 starts to rotate under the action of the fourth large transmission wheel 413, the fourth small transmission wheel 424 and the third belt 425. At the same time, the fifth short rotating rod 422 drives the fifth gear 423 to mesh with the auxiliary gear 421, so that the installation sleeve 419 drives the dust suppression sleeve 420 to start rotating on the outer wall of the cable to be detected. At the same time, in the process of the cable to be detected moving to the rear end, the cleaning cylinder 417 will rotate synchronously with the cable under the action of the adjusting frame 302. When the adjusting frame 302 moves forward, the cleaning cylinder 417 will rotate synchronously with the cable. During movement, since the first clamping plate 209 will fix the cable to be detected, the dust cover 420 will rotate and clean the outer wall of the cable to be detected during the process of rotation and forward movement. In the process of starting the servo motor 202 to make the adjustment frame 302 drive the cable to be continuously circulated, firstly, the segmented detection is adopted to effectively improve the accuracy of cable detection. By alternately clamping the cable by the first clamping plate 209 and the second clamping plate 323, it can be ensured that the cable can avoid missed detection and multiple detection during the segmented detection process, thereby improving the efficiency of cable detection. Secondly, after the detection of a section of cable is completed, When the one-way slider 301 returns to its original position, the surface of the next section of the cable to be tested will be wiped by the dust removal sleeve 420, which improves the cleanliness of the surface of the cable to be tested, effectively reduces the interference of dust, dirt and other impurities on the test results, and improves the accuracy of the test. Thirdly, it is easier to observe minor scratches, cracks and other defects on the cleaned cable surface, which helps to more comprehensively evaluate and detect the condition of the cable, and further improves the accuracy of cable detection. Fourthly, the cable can be circulated and transported, avoiding the staff from holding and pulling the cable with their hands, and reducing the safety hazards of cable leakage to the staff.

[0068] Specifically, the working principle of the safety detection device for circuits is as follows: first, the cable to be detected is placed on the upper surface of the detection table 101. At this time, the cable to be detected passes through the cleaning cylinder 417, and the initial head of the cable to be detected is placed in the middle of the second clamping plate 323. At this time, the servo motor 202 is started to rotate the first large transmission wheel 213 and the second large transmission wheel 215. At this time, under the action of the first belt 216, the first short rotating rod 205 and the adjusting rod 217 begin to rotate. At this time, under the action of the first short rotating rod 205, the first conversion gear 218 and the second conversion gear 219, the first gear cylinder 206 begins to mesh with the first gear plate 207. At the same time, the rotation directions of the first gear cylinders 206 on both sides are inconsistent, so that the first clamping plate 209 is in phase. The first clamping plate 209 moves away from the cable to be detected. At the same time, during the movement of the one-way slider 301, the second gear cylinder 304 will mesh with the third adjusting tooth 328. At this time, under the action of the third gear cylinder 306, the first long rotating rod 305 starts to drive the first gear 307 to rotate. At this time, under the action of the second gear 309, the second short rotating rod 308, the first bevel gear 310 and the second bevel gear 312, the second long rotating rod 311 starts to drive the third gear 313 to rotate. During the mutual meshing of the third gear 313 and the first adjusting tooth 315, the clamping frame 314 will drive the concave frame 316 to move to the right. At this time, the second adjusting tooth 317 will mesh with the fourth gear cylinder 318 during the rightward movement. , and the fourth gear cylinder 318 drives the second gear plate 319 to move to the left. At this time, the two second clamping plates 323 move toward the direction of the cable to be detected and fix the cable to be detected. In the process of the one-way slider 301 moving to the rear end, the cable clamped by the second clamping plate 323 will be driven to move backward synchronously. When the adjustment frame 302 moves to the rearmost position, the servo motor 202 automatically stops. At this time, the staff starts to detect the cable to be detected by using the multimeter 106, the detection wire 107 and the measuring probe 108. When a section of cable is detected, the servo motor 202 is controlled in the opposite direction to move the adjustment frame 302 to the original position. At this time, in the process of the one-way slider 301 and the adjustment frame 302 moving, the first The second clamping plate 323 begins to reset and no longer clamps the cable, and the first clamping plate 209 begins to clamp the cable at the undetected position. Then, when the one-way slider 301 returns to its original position, the servo motor 202 is controlled to rotate in the initial rotation direction, so that the first clamping plate 209 releases the cable to be detected, and the second clamping plate 323 clamps the cable to be detected again and moves the cable. During the movement of the one-way slider 301, the adjustment frame 302 drives the transfer rectangular platform 401, the L-shaped transfer plate 405, the transmission bracket 409, the assembly slide frame 416 and the cleaning cylinder 417 to move synchronously to the rear end. During the movement of the transfer rectangular platform 401, the first gear 307 and the fourth gear 403 engage with each other to rotate the third bevel gear 404.At this time, the third long rotating rod 406 will drive the third large transmission wheel 408 to rotate. At this time, the fourth short rotating rod 410 starts to rotate under the action of the third small transmission wheel 411 and the second belt 412. At this time, the fifth short rotating rod 422 starts to rotate under the action of the fourth large transmission wheel 413, the fourth small transmission wheel 424 and the third belt 425. At the same time, the fifth short rotating rod 422 drives the fifth gear 423 to mesh with the auxiliary gear 421, so that the installation sleeve 419 drives the dust removal sleeve 420 to start rotating on the outer wall of the cable to be detected. At the same time, in the process of the cable to be detected moving to the rear end, the cleaning cylinder 417 will rotate synchronously with the cable under the action of the adjustment frame 302. When the adjustment frame 302 moves forward, the first clamping plate 209 will fix the detection cable, so that the dust removal sleeve 420 will rotate and clean the outer wall of the cable to be detected during the rotation and forward movement.

8. A circuit safety detection method, characterized in that: Using a circuit safety detection device according to any one of claims 1 to 7 to perform circuit detection, comprising the following steps: First, the cable to be tested is placed on the upper surface of the testing table (101), at which time the cable to be tested passes through the cleaning cylinder (417), and the initial head of the cable to be tested is placed in the middle of the second clamping plate (323); At this time, the servo motor (202) is started to rotate the first large transmission wheel (213) and the second large transmission wheel (215). At this time, under the action of the first belt (216), the first short rotating rod (205) and the adjusting rod (217) begin to rotate. At this time, under the action of the first short rotating rod (205), the first conversion gear (218) and the second conversion gear (219), the first gear cylinder (206) begins to mesh with the first gear plate (207). At the same time, the rotation directions of the first gear cylinders (206) on both sides are inconsistent, thereby causing the first clamping plate (209) to move in a direction away from each other, and at the same time, the first clamping plate (209) is away from the cable to be detected; At the same time, during the movement of the one-way slider (301), the second gear cylinder (304) meshes with the third adjustment teeth (328), and at this time, under the action of the third gear cylinder (306), the first long rotating rod (305) starts to drive the first gear (307) to rotate, and at this time, under the action of the second gear (309), the second short rotating rod (308), the first bevel gear (310) and the second bevel gear (312), the second long rotating rod (311) starts to drive the third gear (313) to rotate; During the process of the third gear (313) and the first adjusting tooth (315) meshing with each other, the clamping frame (314) drives the concave frame (316) to move rightward; At this time, the second adjusting tooth (317) will mesh with the fourth tooth cylinder (318) during the process of moving to the right, and the fourth tooth cylinder (318) will drive the second tooth plate (319) to move to the left. At this time, the two second clamping plates (323) will move towards the direction of the cable to be tested and fix the cable to be tested; When the one-way slider (301) moves toward the rear end, the cable clamped by the second clamping plate (323) is driven to move backward synchronously, and when the adjustment frame (302) moves to the rearmost position, the servo motor (202) stops automatically; At this time, the staff begins to test the cable to be tested by using a multimeter (106), a test lead (107) and a measuring probe (108); When a section of the cable is detected, the servo motor (202) is controlled in the opposite direction to move the adjustment frame (302) to the original position. At this time, during the movement of the one-way slider (301) and the adjustment frame (302), the second clamping plate (323) begins to reset and no longer clamps the cable, and the first clamping plate (209) begins to clamp the cable at the undetected position. When the one-way slider (301) returns to the original position, the servo motor (202) is controlled to rotate in the initial rotation direction, so that the first clamping plate (209) releases the cable to be detected, and the second clamping plate (323) clamps the cable to be detected again and moves the cable. During the movement of the one-way slider (301), the adjustment frame (302) drives the transfer rectangular platform (401), the L-shaped transfer plate (405), the transmission bracket (409), the assembly slide frame (416) and the cleaning cylinder (417) to move synchronously toward the rear end; During the movement of the transfer rectangular platform (401), the first gear (307) and the fourth gear (403) mesh with each other to rotate the third bevel gear (404), and the third long rotating rod (406) drives the third large transmission wheel (408) to rotate. At this time, the fourth short rotating rod (410) starts to rotate under the action of the third small transmission wheel (411) and the second belt (412); At this time, the fifth short rotating rod (422) starts to rotate under the action of the fourth large transmission wheel (413), the fourth small transmission wheel (424) and the third belt (425), and at the same time, the fifth short rotating rod (422) drives the fifth gear (423) and the auxiliary gear (421) to mesh with each other, so that the installation sleeve (419) drives the dust suppression sleeve (420) to start rotating on the outer wall of the cable to be detected; At the same time, when the cable to be detected moves toward the rear end, the cleaning cylinder (417) will rotate synchronously with the cable under the action of the adjustment frame (302). When the adjustment frame (302) moves forward, the first clamping plate (209) will fix the cable to be detected, so that the dust removal sleeve (420) will rotate and clean the outer wall of the cable to be detected during the process of rotation and forward movement.
