Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinet detection equipment, and particularly relates to an underground distribution cabinet insulation detection device. Background Art

[0002] An underground distribution cabinet is a new type of distribution cabinet. Its installation method is quite different from that of ordinary distribution cabinets. The cabinet body is buried underground, and its surface generally uses a high-strength stainless steel cover plate. After installation, the cover plate is flush with the ground. Compared with ordinary distribution cabinets, it has the advantages of not occupying roads, not occupying space, and not affecting the flow of people and vehicles. At the same time, it integrates personalized customization such as cover plate filling and self-heating of the cover plate in extremely cold weather, and is suitable for places such as squares, roads, exhibition halls, parks, factories, airports, etc.

[0003] During the production process of the cabinet body plate of the distribution cabinet, after painting on the cabinet body plate, it is usually necessary to detect the insulation of the cabinet body plate. At present, most of the methods for detecting the insulation of the cabinet body plate are to randomly select several points on the cabinet body plate for detection. This detection method has great limitations and is extremely prone to missed detection.

[0004] In the prior art, the invention patent with the publication number CN115184754A provides an insulation detection device for a distribution cabinet, including a base, a slide rail is provided on the base, a slide seat is slidably connected to the slide rail, a bottom plate is fixedly connected to the slide seat, a cross bar is provided at the lower end of the bottom plate, a propulsion part is provided below the bottom plate, a support seat is provided on the base, a support shaft is rotatably connected to the support seat, a detection part is provided on the support shaft, and a driving part is provided on the support seat.

[0005] During the detection process, whenever the propulsion part drives the cabinet body plate to move forward once, the driving part drives a detection part to rotate to a position corresponding to the cabinet body plate, and the insulation of the cabinet body plate is detected by multiple contact heads of the detection part. Although this insulation detection device improves the comprehensiveness of detection to a certain extent.

[0006] However, there is a certain gap between two adjacent contact heads. At the same time, after one detection is completed, the propulsion part drives the cabinet body plate to move forward a preset distance before the next detection is carried out, resulting in a detection gap between two detections. Therefore, the detection is still not comprehensive enough. In addition, since its detection circuit is power supply - contact head - cabinet body plate - bottom plate - power supply, as long as one side of the cabinet body plate has poor insulation and the other side has good insulation, it will cause the detection circuit to be in an open state, resulting in detection failure. Summary of the Invention

[0007] Aiming at the defects in the prior art, the purpose of the present invention is to provide an underground distribution cabinet insulation detection device to solve or alleviate the above-mentioned technical problems existing in the prior art.

In its natural state, it applies an elastic force to the inner rod, causing the inner rod to tend to move downward.

[0026] Such as Figures 1 - 11As shown in the figure, the present invention provides a buried power distribution cabinet insulation detection device, which includes a machine body 100, a bearing seat 200, a driving component and a detection component.

[0027] Among them, a cabinet 800 is arranged on the machine body 100. The bearing seat 200 has a first position and a second position. The bearing seat 200 is slidably connected to the machine body 100, so that the bearing seat 200 can only make a reciprocating linear motion between the first position and the second position along the X-axis direction. Specifically, as Figure 1 shown, a first guide rail 110 is arranged on the machine body 100, and the bearing seat 200 is connected to the machine body 100 through the first guide rail 110.

[0028] The driving component is arranged on the machine body 100. The driving component is in transmission connection with the bearing seat 200, and the driving component is used to drive the bearing seat 200 to make a reciprocating linear motion between the first position and the second position.

[0029] The detection component is arranged on the machine body 100 and above the bearing seat 200. The detection component includes a mounting seat 300 and a contact head group.

[0030] Among them, the mounting seat 300 is arranged on the machine body 100 and above the bearing seat 200. The contact head group is arranged on the mounting seat 300. The contact head group includes a plurality of contact head modules. The plurality of contact head modules are sequentially arranged at intervals along the Y-axis direction. The contact head module includes a positive contact head and a negative contact head that are arranged in parallel and insulated from each other. The positive contact head and the negative contact head are respectively electrically connected to the positive pole and the negative pole of the power supply.

[0031] During detection, the contact head module abuts against the top surface of the target cabinet board. The driving component drives the bearing seat 200 to move from the first position to the second position or from the second position to the first position, so that the plurality of contact head modules of the contact head group move on the top surface of the target cabinet board, thereby continuously detecting the top surface of the target cabinet board, so as to achieve the purpose of improving the comprehensiveness of detection.

[0032] Specifically, during detection, the A surface of the cabinet board is facing up, and the contact head module can abut against the A surface of the target cabinet board. The driving component drives the bearing seat 200 to move from the first position to the second position or from the second position to the first position, so that the contact head module slides on the A surface of the target cabinet board. When the insulation of the cabinet board is good, the positive contact head and the negative contact head are disconnected, so that the detection circuit is disconnected; when there is leakage at the corresponding position of the contact head module, the positive contact head and the negative contact head can be connected, and the detection circuit is connected, so as to achieve the purpose of detecting the insulation of the cabinet board.

[0033] The detection method for the B surface of the cabinet board is the same as that for the A surface of the cabinet board, and will not be elaborated here.

[0034] In the underground distribution cabinet insulation detection device provided by the present invention, during detection, when the bearing base 200 moves, the contact module always contacts the top surface of the target cabinet plate, so that the detection of the cabinet plate is more comprehensive.

[0035] like Figure 1 As shown, preferably, the mounting seat 300 is slidably connected to the machine body 100, and the mounting seat 300 can reciprocate between the third position and the fourth position along the Z-axis direction. Specifically, the machine body 100 is provided with a second guide rail 120, and the mounting seat 300 is slidably connected to the machine body 100 through the second guide rail 120.

[0036] The body 100 is provided with a driving device 700, which is in transmission connection with the mounting seat 300 to drive the mounting seat 300 to perform reciprocating linear motion between the third position and the fourth position. In the working state, the mounting seat 300 is driven by the driving device 700 to move, so as to change the position of the mounting seat 300 in the Z-axis direction, thereby achieving the purpose of detecting cabinet panels of different thicknesses. Figure 1 As shown, the driving device 700 is an electric push rod.

[0037] like Figure 1 As shown, the driving assembly includes a lead screw 410 , a motor 420 , and a nut 430 .

[0038] Wherein, the lead screw 410 is arranged on the machine body 100, the axis of the lead screw 410 extends along the X-axis direction, and the lead screw 410 is rotatably connected to the machine body 100. The motor 420 is arranged on the machine body 100, the motor 420 is fixedly connected to the machine body 100, and the power output shaft of the motor 420 is transmission-connected to the power input end of the lead screw 410. The nut 430 is sleeved on the lead screw 410. The nut 430 is transmission-connected to the lead screw 410 so that when the lead screw 410 rotates, the nut 430 can be driven to move along the axis direction of the lead screw 410. The nut 430 is transmission-connected to the bearing seat 200 so that the nut 430 can transmit power to the bearing seat 200 to drive the bearing seat 200 to move. In this embodiment, the nut 430 is fixedly connected to the bearing seat 200.

[0039] When in use, the motor 420 drives the lead screw 410 to rotate, so that the nut 430 moves with the bearing seat 200 along the axis direction of the lead screw 410. Specifically, when the motor 420 drives the lead screw 410 to rotate in the positive direction, the nut 430 moves in the positive direction of the X axis, so that the bearing seat 200 moves from the first position to the second position; when the motor 420 drives the lead screw 410 to rotate in the reverse direction, the nut 430 moves in the negative direction of the X axis, so that the bearing seat 200 moves from the second position to the first position.

[0040] In other embodiments, the driving assembly includes an electric push rod. The electric push rod is fixedly installed on the bearing seat 200, and the power output shaft of the electric push rod is in transmission connection with the bearing seat 200. By the telescopic movement of the electric push rod, the bearing seat 200 is driven to perform a reciprocating linear motion between the first position and the second position.

[0041] In other embodiments, the driving assembly includes a transmission wheel, a synchronous belt and a motor.

[0042] Among them, the transmission wheel is rotatably connected to the machine body 100. There are two transmission wheels, and the two transmission wheels are arranged at intervals along the X-axis direction. The transmission belt is sleeved on the transmission wheels and can rotate with the rotation of the transmission wheels. The motor is fixedly installed on the machine body 100, and the power output shaft of the motor is in transmission connection with one of the transmission wheels to drive the transmission wheel to rotate. The bearing seat 200 is fixedly connected to the horizontal section of the transmission belt.

[0043] During use, the motor drives the transmission wheel to rotate, thereby driving the bearing seat 200 to move through the synchronous belt. Specifically, when the motor drives the transmission wheel to rotate forward, the bearing seat 200 is driven to move from the first position to the second position through the synchronous belt; when the motor drives the transmission wheel to rotate in the reverse direction, the bearing seat 200 is driven to move from the second position to the first position through the synchronous belt.

[0044] Since there is always a gap between multiple contact modules of a contact group, in order to further improve the comprehensiveness of the detection of the cabinet board. In this embodiment, multiple contact groups are provided, and the multiple contact groups are arranged at intervals in sequence along the X-axis direction, and the projections of the contact modules of all the contact groups on the YOZ plane do not overlap, so that any one contact module can detect different positions of the cabinet board, thereby achieving the purpose of further improving the comprehensiveness of its detection of the cabinet board.

[0045] Preferably, any two adjacent projections in the projections of all the contact modules on the YOZ plane have an overlapping area, so that there is no detection gap between any two adjacent contact modules, thereby achieving the purpose of comprehensively detecting the top surface of the cabinet board.

[0046] As Figure 5 、 Figure 8 shown, the positive contact and the negative contact include a mounting rod 510, a rolling element 520, a first electrode block 530 and a first elastic element 540.

[0047] The first end of the mounting rod 510 is connected to the mounting base 300, and the second end extends downward. The rolling element 520 has conductivity. The roller element is arranged at the second end of the mounting rod 510, and the rolling element 520 can roll on the side wall of the target cabinet board. The first electrode block 530 is arranged in the mounting rod 510. The first electrode block 530 is slidably connected to the mounting rod 510 so that the first electrode block 530 can only move along the axis direction of the mounting rod 510. One side of the first electrode block 530 facing the rolling element 520 abuts against the side wall of the rolling element 520.

[0048] The first elastic element 540 is arranged in the mounting rod 510. Two ends of the first elastic element 540 are respectively connected to the first electrode block 530 and the mounting rod 510. In the natural state, the first elastic element 540 applies an elastic force to the first electrode block 530 so that the first electrode block 530 has a tendency to move in the direction close to the rolling element 520, thereby making the first electrode block 530 always in contact with the rolling element 520. The first elastic element 540 can be any element that can apply an elastic force to the first electrode block 530. In this embodiment, the first elastic element 540 is a spring.

[0049] During use, the rolling element 520 abuts against the top surface of the target cabinet board. During the process that the driving component drives the carrier 200 to move from the first position to the second position or from the second position to the first position, the rolling element 520 rolls on the top surface of the cabinet board, so as to achieve the purpose of reducing the friction between the contact module and the cabinet board, and further achieve the purpose of avoiding scratching the cabinet board. When there is leakage at the corresponding position of the contact module, the positive contact and the negative contact are connected by the cabinet board, so that the detection circuit is connected, and further achieve the purpose of detecting the insulation of the cabinet board.

[0050] In this embodiment, for the positive contact and the negative contact provided, by arranging the rolling element 520, the purpose of reducing the friction between the contact module and the cabinet board is achieved, and further the purpose of avoiding scratching the cabinet board is achieved.

[0051] Optionally, the rolling element 520 is a roller or a ball.

[0052] Since the roller is in line contact with the cabinet board and the ball is in point contact with the cabinet board. Therefore, preferably, the rolling element 520 is a roller to achieve the purpose of improving the comprehensiveness of the detection of the cabinet board.

[0053] As Figure 11 shown, in order to avoid being unable to detect due to too small a leakage area. Therefore, preferably, a plurality of elastic electrode wires 521 are arranged on the outer peripheral wall of the roller.

[0054] As Figure 5 、 Figure 8As shown, the mounting rod 510 includes an outer rod 511, an inner rod 512, and a second elastic element 513.

[0055] The first end of the outer rod 511 is connected to the mounting base 300, and the second end extends downward. The inner rod 512 is coaxially inserted into the outer rod 511 and is slidably connected to the outer rod 511 so that the inner rod 512 can only move along the axis of the outer rod 511. The second elastic element 513 is sleeved on the inner rod 512, and both ends of the second elastic element 513 are respectively connected to the outer rod 511 and the inner rod 512. In the natural state, the second elastic element 513 applies an elastic force to the inner rod 512 so that the inner rod 512 has a tendency to move downward.

[0056] As Figure 4 、 Figure 7 shown, the positive electrode contact and the negative electrode contact further include an electrode rod 550.

[0057] The electrode rod 550 is inserted into the mounting rod 510 and is slidably connected to the mounting rod 510 so that the electrode rod 550 can only move along the axis of the mounting rod 510. The first end of the electrode rod 550 is fixedly connected to the first electrode block 530, and the second end extends outside the mounting rod 510. The carrier seat 200 is correspondingly provided with a jack 310 for the electrode rod 550 and the mounting rod 510 to be inserted. An elastic electrode module electrically connected to the power source is arranged in the jack 310. When the electrode rod 550 is inserted into the jack 310, the electrode rod 550 is electrically connected to the elastic electrode module.

[0058] As Figure 3 、 Figure 6 shown, the elastic electrode module includes a second electrode block 610 and a control structure.

[0059] The second electrode block 610 is slidably connected to the mounting base 300. There are two second electrode blocks 610, and the two second electrode blocks 610 are symmetrically arranged on both sides of the jack 310. The control structure is arranged on the mounting base 300 and is used to control the two second electrode blocks 610 to approach or separate from each other. When the electrode rod 550 is inserted into the jack 310, the control structure controls the two second electrode blocks 610 to approach each other so that the second electrode block 610 abuts against the electrode rod 550. When it is necessary to replace the positive electrode contact or the negative electrode contact, the control structure controls the two second electrode blocks 610 to separate from each other so that the second electrode block 610 is separated from the electrode rod 550.

[0060] As Figure 4 、 Figure 5 、 Figure 7 、 Figure 8As shown, preferably, a first limiting groove 551 is provided on the outer side wall of the electrode rod 550, and a first limiting portion 611 is correspondingly provided on the second electrode block 610. In the working state, the first limiting groove 551 cooperates with the first limiting portion 611 to enable the positive electrode contact or the negative electrode contact to be firmly inserted into the jack 310.

[0061] As Figure 10 shown, preferably, a second limiting portion 514 is provided at the first end of the mounting rod 510, and a second limiting groove 320 is correspondingly provided on the side wall of the jack 310. In the working state, through the cooperation of the second limiting groove 320 and the second limiting portion 514, the rotation of the mounting rod 510 is prevented. At the same time, through the positional relationship between the second limiting groove 320 and the second limiting portion 514, the positive electrode contact or the negative electrode contact can also be quickly installed in the correct orientation.

[0062] Specifically, when in use, after the electrode rod 550 is inserted into the jack 310, the two second electrode blocks 610 are controlled to approach each other through the control structure, and the first limiting portion 611 is inserted into the first limiting groove 551. Under the cooperation of the first limiting groove 551 and the first limiting portion 611, the positive electrode contact or the negative electrode contact can be firmly inserted into the corresponding jack 310.

[0063] When it is necessary to replace the positive electrode contact or the negative electrode contact, the two second electrode blocks 610 are controlled to move away from each other through the control structure, and the first limiting portion 611 and the first limiting groove 551 move away from each other, so as to achieve the purpose of being able to pull out the positive electrode contact or the negative electrode contact, and further achieve the purpose of facilitating the installation, disassembly, and replacement of the positive electrode contact or the negative electrode contact.

[0064] As Figure 4 、 Figure 7 shown, the control structure includes a winding drum 620, a knob 630, a pull rope 640, and a third elastic element 650.

[0065] The winding drum 620 is arranged in the mounting seat 300 and is rotatably connected to the mounting seat 300. The knob 630 is arranged on the top of the mounting seat 300, and the knob 630 is sleeved on the power input shaft of the winding drum 620. Two pull ropes 640 are provided and respectively correspond to the two second electrode blocks 610. The first end of the pull rope 640 is connected to the winding drum 620, and the second end is connected to the second electrode block 610. Two third elastic elements 650 are provided and respectively correspond to the two second electrode blocks 610. The two ends of the third elastic element 650 are respectively connected to the mounting seat 300 and the second electrode block 610. In the natural state, the third elastic element 650 applies an elastic force to the second electrode block 610, so that the second electrode block 610 has a tendency to move in the direction close to the axis of the jack 310.

[0066] Specifically, when it is necessary to disassemble the positive electrode contact or the negative electrode contact, the knob 630 is rotated to drive the reel 620 to wind up the pulling rope 640, so that a pulling force is applied to the second electrode block 610 through the pulling rope 640, causing the two second electrode blocks 610 to move away from each other, so that the first limiting portion 611 and the first limiting groove 551 move away from each other, and thus the purpose of being able to pull out the positive electrode contact or the negative electrode contact is achieved.

[0067] After the positive electrode contact or the negative electrode contact is inserted into the jack 310, the knob 630 is released. Under the action of the elastic force of the third elastic element 650, the two second electrode blocks 610 move closer to each other, so that the first limiting portion 611 is inserted into the first limiting groove 551, and the purpose of installing the positive electrode contact or the negative electrode contact can be achieved.

[0068] In the description of the present invention, a large number of specific details are set forth.
