Description

Technical Field

[0001] The present invention relates to the technical field of insulation detection equipment, and more specifically, to an insulation detection device and a detection method for the production of electric control cabinets. Background Art

[0002] In order to ensure the most basic safety of electrical products during use, that is, to ensure that they have good insulation performance during use, so that personnel will not be in danger of electric shock when using them. Electrical products such as electric control cabinets need to be subjected to a withstand voltage test after being assembled and leaving the factory. The basic principle of the withstand voltage test: Apply a voltage higher than the normal operating voltage to the insulator of the device under test and maintain it for a specified period of time. If the insulation during this period is good enough, only a very small leakage current will be generated by the applied voltage. If the leakage current of an insulator of a device under test remains within the specified range within the specified time, it can be determined that this device under test can operate safely under normal operating conditions.

[0003] Currently, when using a withstand voltage tester to detect the insulation of electrical components arranged inside an electric control cabinet, personnel need to hold a detection pen by hand and touch the tip of the detection pen against the detection point on the electrical component, usually a terminal. During this process, personnel need to search for each detection point at close range, which is difficult to operate. And because there are many electrical components neatly distributed in the electric control cabinet, and the detection of each phase takes about 10 seconds, this makes personnel need to hold the detection pen in a certain posture and with a certain force to maintain a relatively static state, greatly increasing the burden on the staff. Facing numerous electric control cabinets about to leave the factory, the staff is difficult to bear. In addition, when personnel perform insulation detection on each electrical component at a high voltage state at close range, once personnel accidentally touch an electrical component with poor insulation, it will pose a great safety hazard to the staff.

[0004] In view of this, the present invention proposes an insulation detection device and a detection method for the production of electric control cabinets. Summary of the Invention

A large U-shaped frame is fixedly connected to the outer wall of the transverse movement seat. A connecting spring is connected between the tail block and the transverse movement seat, and the connecting spring is sleeved outside the detection pen; A traction assembly is arranged on one side of the transverse movement seat.

An expansion rod is connected between the winding roller and the turntable.

[0015] An insulation detection method for the production of electrical control cabinets includes the following steps: Step 1: Install the rectangular frame on the front side of the cabinet. Adjust the length and width of the rectangular frame structure according to the size of the cabinet. The length of the entire rectangular frame can be adjusted by adjusting the distance between two adjacent assembly sections, and the width of the entire rectangular frame can be adjusted by adjusting the distance between two adjacent right-angle frames on the left and right. At this time, the distance between two adjacent short sections can be adjusted accordingly, stretching or compressing the return spring. The lead screw can be a lead screw with a length selected according to actual requirements and installed through the insert block and bolts. The entire rectangular frame is installed and fixed on the front side of the cabinet through the fastening bolts and the right-angle frame; Step 2: Before the detection work, as Figure 8 shown, the direction of the light irradiated by the laser lamp and the position pointed by the end of the detection pen are on the same straight line. The position where the laser lamp irradiates on the electrical component represents the position where the detection pen needs to touch. The camera takes pictures of the irradiation point of the laser lamp, and the camera shooting result can be displayed on the display screen of the PLC controller, so that the detection personnel can search for the detection point at a distance; Step 3: During the process of searching for the detection point on the electrical component, start the first motor. The first motor drives the lead screw to rotate, so as to be able to horizontally adjust the position of the transverse movement seat, and then be able to horizontally adjust the position of the detection pen. By starting the second motor, the second motor winds and unwinds the traction rope through the winding roller. When the winding roller relaxes the traction rope, under the action of the coil spring, the winding roller winds the traction rope, so that the traction rope drives the fixed block to move downward. When the winding roller winds the traction rope, the traction rope drives the fixed block to move upward, so as to be able to adjust the height of the auxiliary mechanism through the horizontal adjustment component, and then be able to adjust the working height of the detection pen; Step 4: During the process of adjusting the position of the auxiliary mechanism through the horizontal adjustment component and the lifting component, the telescopic rod can telescopically adapt. At the same time, the telescopic rod can also drive the support plate to move horizontally through the turntable, and the directional wheel assists the support plate to move. In order to further improve the stability of the horizontal movement of the support plate, a track matching the directional wheel can also be set under the support plate, so that the support plate can move horizontally smoothly through the directional wheel; Step 5: During the process of adjusting the position of the auxiliary mechanism through the horizontal adjustment component and the lifting component, as Figure 2 and Figure 8 shown, the connecting spring is in a stretched state. At this time, the pull rope can pull the tail stop block, and the plug is inserted into the jack to limit the turntable to prevent the turntable from rotating self; Step 6: When the laser light points to the detection point on the electrical component to be measured, manually rotate the turntable, so that the telescopic rod drives the winding roller to rotate, release the pulling rope, make the connecting spring contract, and make the detection pen move towards the electrical component until the tip of the detection pen touches the detection point on the electrical component; Step 7: During the movement of the detection pen, the suspension rope can be pulled, so that the suspension rope pulls up the suspension plate, and the suspension plate moves away from the front end of the detection pen, ensuring that the suspension plate does not affect the forward movement of the detection pen.

[0016] The working principle and beneficial effects of the present invention are as follows: In the present invention, a displacement transmission mechanism is installed on the front side of the cabinet body. Through the rectangular frame on the displacement transmission mechanism, the displacement transmission mechanism can be installed on cabinets of different sizes. The auxiliary mechanism is used to install the detection pen and assist the detection pen to find the detection point on the component to be measured. During the process of finding the detection point on the electrical component, the lifting component and the horizontal adjustment component can be used to adjust the position of the auxiliary mechanism in a vertical plane. In addition, the direction of the light irradiated by the laser lamp on the auxiliary mechanism is on the same straight line as the position pointed by the end of the detection pen. The position where the laser lamp irradiates on the electrical component represents the position where the detection pen is to be in contact. The irradiation point of the laser lamp is photographed by the camera, and the photographing result of the camera can be displayed on the display screen of the PLC controller, so that the detection personnel can find the detection point from a distance, without the need for personnel to find the detection point close to the inside of the cabinet body. The operation is simple and convenient, reducing the risk of accidental touch by personnel and significantly improving the safety performance; In the present invention, during the process of adjusting the position of the auxiliary mechanism by the horizontal adjustment component and the lifting component, the telescopic rod can extend and contract adaptively. At the same time, the telescopic rod can also drive the support plate to move horizontally through the turntable, so that the linkage component will not hinder the work of the horizontal adjustment component and the lifting component. In addition, when the laser light points to the detection point on the electrical component to be measured, manually rotate the turntable on the linkage component, so that the telescopic rod drives the winding roller to rotate, release the pulling rope, make the connecting spring contract, and make the detection pen move towards the electrical component until the tip of the detection pen touches the detection point on the electrical component for detection, without the need for personnel to hold the detection pen in a certain posture and with a certain force for a long time, significantly reducing the burden on the staff; In the present invention, during the process of the detection pen moving towards the electrical component, the suspension rope can be pulled, causing the suspension rope to pull up the suspension plate, so that the suspension plate moves away from the front end of the detection pen and does not block the advancement of the detection pen. After the detection is completed, when the detection pen moves away from the electrical component, the suspension plate automatically moves down and resets, and the direction of the light irradiated by the laser lamp on the auxiliary mechanism can be on the same straight line as the position pointed by the end of the detection pen. The position where the laser lamp irradiates on the electrical component represents the position to be contacted by the detection pen. The structure is simple and ingeniously designed, and can cooperate well with the detection work of the detection pen, with high application value. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Specifically, the linkage component 53 includes a support plate 531. At the bottom corners of the support plate 531, there are directional wheels 5311. A turntable 532 is rotatably connected to the upper side of the support plate 531. A plug-in member 538 is slidably sleeved inside the turntable 532.

[0032] In this embodiment, before the detection work is carried out, as Figure 8 shown, the direction of the light irradiated by the laser lamp 558 and the position pointed by the end of the detection pen 11 are on the same straight line. The position where the laser lamp 558 irradiates on the electrical component 4 represents the position that the detection pen 11 is to contact. The camera 556 takes pictures of the irradiation point of the laser lamp 558. The imaging result of the camera 556 can be displayed on the display screen of the PLC controller 2, so that the detection personnel can search for the detection points at a long distance.

[0033] In this embodiment, during the process of adjusting the position of the auxiliary mechanism 55 through the lateral adjustment component 54 and the lifting component 52, the expansion link 533 can expand and contract adaptively. At the same time, the expansion link 533 can also drive the support plate 531 to move horizontally through the turntable 532. The directional wheels 5311 assist the support plate 531 to move. In order to further improve the stability of the horizontal movement of the support plate 531, a track that cooperates with the directional wheels 5311 can also be provided on the lower side of the support plate 531, so that the support plate 531 can move horizontally smoothly through the directional wheels 5311. During the process of adjusting the position of the auxiliary mechanism 55 through the lateral adjustment component 54 and the lifting component 52, as Figure 2 and Figure 8 shown, the connecting spring 553 is in an extended state. At this time, the pull rope 536 can pull the tail stop 13. The plug-in member 538 is inserted into the jack 539 to limit the turntable 532 and prevent the turntable 532 from rotating self.

[0034] In this embodiment, when the light of the laser lamp 558 points to the detection point on the electrical component 4 to be measured, the turntable 532 is manually rotated (of course, according to actual needs, the manual drive of the turntable 532 can also be replaced by an electric drive of a motor, which is a mature existing technology and will not be elaborated here). The telescopic rod 533 drives the winding roller 534 to rotate, releases the pull rope 536, causes the connecting spring 553 to contract, and makes the detection pen 11 move in the direction close to the electrical component 4 until the tip of the detection pen 11 touches the detection point on the electrical component 4. During the movement of the detection pen 11, the suspension rope 5543 can be pulled, causing the suspension rope 5543 to pull up the suspension plate 557, so that the suspension plate 557 moves away from the front end of the detection pen 11 and does not block the forward movement of the detection pen 11.

[0035] Working principle and usage process: Step 1: Install the rectangular frame 51 on the front side of the cabinet 3. According to the size of the cabinet 3, adjust the length and width of the structure of the rectangular frame 51 accordingly. By adjusting the distance between two adjacent assembly sections 514, the length of the entire rectangular frame 51 can be adjusted. By adjusting the distance between two adjacent right-angle frames 511 on the left and right, the width of the entire rectangular frame 51 can be adjusted. At this time, the distance between two adjacent short sections 546 can be adjusted accordingly, stretching or compressing the return spring 549. The lead screw 545 can be a lead screw 545 with a selectable length according to actual requirements and is installed through the insert block 548 and bolts. The entire rectangular frame 51 is installed and fixed on the front side of the cabinet 3 through the fastening bolt 512 and the right-angle frame 511. Step 2: Before the detection work, as Figure 8 shown, the direction of the light irradiated by the laser lamp 558 and the position pointed by the end of the detection pen 11 are on the same straight line. The position where the laser lamp 558 irradiates on the electrical component 4 represents the position where the detection pen 11 is to touch. The irradiation point of the laser lamp 558 is photographed by the camera 556, and the photographing result of the camera 556 can be displayed on the display screen of the PLC controller 2, so that the detection personnel can search for the detection point at a distance. Step 3: During the process of searching for the detection points on the electrical component 4, start the first motor 544. The first motor 544 drives the lead screw 545 to rotate, so as to horizontally adjust the position of the transverse movement seat 551, and then horizontally adjust the position of the detection pen 11. By starting the second motor 523, the second motor 523 winds and unwinds the traction rope 522 through the winding roller 524. When the winding roller 524 relaxes the traction rope 522, under the action of the coil spring 527, the winding roller 526 winds the traction rope 522, so that the traction rope 522 drives the fixed block 542 to move downward. When the winding roller 524 winds the traction rope 522, the traction rope 522 drives the fixed block 542 to move upward, so as to adjust the height of the auxiliary mechanism 55 through the horizontal adjustment component 54, and then adjust the working height of the detection pen 11; Step 4: During the process of adjusting the position of the auxiliary mechanism 55 through the horizontal adjustment component 54 and the lifting component 52, the telescopic rod 533 can telescopically adapt. At the same time, the telescopic rod 533 can also drive the support plate 531 to move horizontally through the turntable 532. The idler wheel 5311 assists the support plate 531 to move. In order to further improve the stability of the horizontal movement of the support plate 531, a track matching with the idler wheel 5311 can also be arranged on the lower side of the support plate 531, so that the support plate 531 can move horizontally smoothly through the idler wheel 5311; Step 5: During the process of adjusting the position of the auxiliary mechanism 55 through the horizontal adjustment component 54 and the lifting component 52, as Figure 2 and Figure 8 shown, the connecting spring 553 is in a stretched state. At this time, the pull rope 536 can pull the tail stop block 13, and the plug 538 is inserted into the jack 539 to limit the turntable 532 to prevent the turntable 532 from rotating self - clockwise; Step 6: When the light of the laser lamp 558 points to the detection point on the electrical component 4 to be measured, manually rotate the turntable 532, so that the telescopic rod 533 drives the winding roller 534 to rotate, release the pull rope 536, so that the connecting spring 553 contracts, and the detection pen 11 moves towards the electrical component 4 until the tip of the detection pen 11 touches the detection point on the electrical component 4; Step 7: During the movement of the detection pen 11, it can pull the suspension rope 5543, so that the suspension rope 5543 pulls up the suspension plate 557, and the suspension plate 557 moves away from the front end of the detection pen 11 to ensure that the suspension plate 557 does not affect the forward movement of the detection pen 11.
