Description

Technical Field

[0001] The invention relates to the technical field of power equipment detection, and in particular to a FTU detection tool. Background Art

[0002] FTU is called "feeder terminal unit" or "distribution switch monitoring terminal" in Chinese. It is usually installed next to the outdoor pole switch. It adopts advanced digital signal processing technology, multi-CPU integration technology and high-speed industrial network communication technology. It has the characteristics of strong stability, high reliability and good real-time performance. It is suitable for automation projects of urban, rural and enterprise distribution networks, and cooperates with distribution substations and master stations to realize normal monitoring and fault identification of distribution lines.

[0003] FTU is a key device in the distribution network automation system, mainly used to monitor and control the operating status of the distribution line. It can realize real-time monitoring of electrical parameters such as current and voltage, as well as remote control and fault detection of switchgear. The performance and reliability of FTU directly affect the stability and power supply quality of the distribution network. Therefore, after the FTU is assembled and produced, it needs to be tested to ensure the normal operation of FTU.

[0004] In the existing FTU detection process, there are some problems that need to be solved. First, most traditional FTU detection tools require manual wiring and disassembly, which not only increases the labor intensity of workers, but also may lead to low detection efficiency.

[0014] Beneficial effect: The present invention drives the support block to move through the gap via a conveyor belt, thereby intermittently driving the FTU to move to the inspection station for inspection, so that the inspection work can be carried out in an orderly manner. When the electric push rod drives the mounting seat to move forward, it can first drive the clamping block to move to clamp the FTU through the cooperation of the contact wheel and the wedge block, and at the same time, the rotating frame drives the electromagnet to move downward to contact and adsorb the cabinet door of the FTU, and then the rotating frame drives the electromagnet to move upward to open the cabinet door of the FTU.

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0028] Embodiment: A FTU detection tool, such as Figure 1-6 As shown, it includes a mounting platform 1, a housing 101, a safety door 102, a transmission mechanism, an electric push rod 31, a mounting seat 32, a detection plug 33, an infrared sensor 34 and a detection block 35. The housing 101 is arranged in the middle of the top of the mounting platform 1, and the safety door 102 is installed in the middle of the front side of the housing 101. The mounting platform 1 is provided with a transmission mechanism, which can intermittently transport the FTU0. The electric push rod 31 is installed on the rear side of the top of the mounting platform 1, and the end of the telescopic rod of the electric push rod 31 is connected to the mounting seat 32. The detection plug 33 is detachably installed on the mounting seat 32, and the detection plug 33 can be replaced and adjusted according to the situation of the FTU0. An infrared sensor 34 is installed on the top front side of the mounting table 1. The infrared sensor 34 and the electric push rod 31 are arranged opposite to each other front and back. A detection block 35 is arranged on the transmission mechanism. A controller is arranged in the mounting table 1. The electric push rod 31 and the infrared sensor 34 are electrically connected to the controller. The infrared sensor 34 can detect the position of the detection block 35. When one of the detection blocks 35 moves to the position directly below the infrared sensor 34, the infrared sensor 34 can send a signal. After receiving the signal, the controller controls the transmission mechanism to suspend the transportation of FTU0, and at the same time controls the electric push rod 31 to extend so that the detection plug 33 is inserted into FTU0 for detection.

[0029] like Figure 1-5As shown, the transmission mechanism includes a transmission shaft 21, a conveyor belt 22, a first motor 23, a gear 24 and a support block 25. The front and rear sides of the mounting platform 1 are both symmetrically connected to the transmission shaft 21 for rotation. The left and right transmission shafts 21 on the same side are both wound with a conveyor belt 22 through a transmission wheel. The mounting platform 1 is equipped with a first motor 23, which is electrically connected to the controller. The output shaft of the first motor 23 is connected to one of the transmission shafts 21. The two transmission shafts 21 on the left are both connected to gears 24. The left part of the mounting platform 1 is also rotatably connected to two meshing gears 24, and the two meshing gears 24 are respectively meshed with the gears 24 on the two transmission shafts 21. Six groups of support blocks 25 are evenly spaced and connected to the conveyor belt 22. Every two support blocks 25 form a group. The support blocks 25 are L-shaped. The two groups of support blocks 25 on the two conveyor belts 22 5 is used to support and place the FTU0. The number of the detection blocks 35 is consistent with the number of the support blocks 25. The detection blocks 35 are connected to the top of the conveyor belt 22 on the front side and are located in the middle of each group of support blocks 25. When the first motor 23 rotates, it drives the connected transmission shaft 21 to rotate, so that the conveyor belts 22 on both sides rotate in the opposite direction through the cooperation of the gear 24. When the first motor 23 is suspended, the FTU0 can be placed at the left part of the installation platform 1 and located between the two groups of support blocks 25 corresponding to the two conveyor belts 22. The FTU0 is supported and placed by the support blocks 25. When the conveyor belt 22 continues to rotate, the FTU0 can be transported to the left. When the FTU0 moves to the front of the detection plug 33, the detection plug 33 can be inserted into the FTU0 for detection, and the detected FTU0 is moved out from the left part of the installation platform 1.

[0030] like Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, it also includes a guide plate 41, a rotating block 42, a torsion spring 43, a connecting rod 44, a sliding frame 45, a clamping block 46, a wedge block 47, a return spring 48, a first clamping block 49, a second clamping block 410 and a contact wheel 411. The middle part of the mounting platform 1 is connected to the guide plate 41, the guide plate 41 is located below the conveyor belt 22, the middle part of the guide plate 41 is rotatably connected to the rotating block 42, a torsion spring 43 is connected between the rotating block 42 and the guide plate 41, both ends of the rotating block 42 are rotatably connected to the connecting rod 44, the front and rear sides of the guide plate 41 are slidably connected to the sliding frame 45, and the two connecting rods 44 are respectively rotatable with the two sliding frames 45 The sliding frame 45 is connected to the sliding frame 45 symmetrically with two clamping blocks 46, which pass through the top of the mounting platform 1. The sliding frame 45 on the rear side is slidably connected with a wedge block 47, and a return spring 48 is connected between the wedge block 47 and the sliding frame 45. A contact wheel 411 is installed at the bottom of the mounting seat 32, and the contact wheel 411 contacts and cooperates with the wedge block 47. The stiffness of the return spring 48 is greater than that of the torsion spring 43. A first clamping block 49 is connected to the bottom of the wedge block 47, and a second clamping block 410 is connected to the top rear side of the guide plate 41. The first clamping block 49 moves downward to engage with the second clamping block 410; the mounting seat 32 drives the contact wheel When the mounting bracket 32 ​​moves forward, the contact wheel 411 contacts the wedge block 47 and can drive the rear sliding frame 45 to move forward, so that the front sliding frame 45 moves backward synchronously through the cooperation of the connecting rod 44 and the rotating block 42, the torsion spring 43 is deformed, and the clamping blocks 46 on the front and rear sides move toward each other to clamp the FTU0. At this time, the wedge block 47 cannot move forward any further. As the mounting bracket 32 ​​continues to move forward, the contact wheel 411 squeezes the wedge block 47 to move downward, the reset spring 48 is compressed, and the wedge block 47 drives the first clamping block 49 to move downward and engage with the second clamping block 410, thereby limiting the movement of the sliding frame 45. At this time, the contact wheel 411 contacts the top surface of the wedge block 47 to limit the upward movement of the wedge block 47, and then the mounting seat 32 drives the detection plug 33 to be inserted into the interface of the FTU0 for detection. After the detection is completed, the mounting seat 32 drives the detection plug 33 to move backward and be pulled out from the interface of the FTU0. After the contact wheel 411 moves from the top plane of the wedge block 47 to the inclined surface, the reset spring 48 drives the wedge block 47 to move upward, and the first clamping block 49 is separated from the second clamping block 410. As the mounting seat 32 and the contact wheel 411 continue to move backward, the torsion spring 43 drives the rotating block 42 to rotate and reset, so that the sliding frames 45 on both sides drive the clamping blocks 46 to move away from each other and reset.

[0031] like Figure 2 , Fig. 9 and Fig.10As shown, it also includes a mounting frame 51, a CCD visual detector 53, a screw 54, a second motor 55 and a belt transmission assembly 56. The mounting frame 51 is installed on the upper part of the casing 101. Two slide grooves 52 are provided on the mounting frame 51. The CCD visual detector 53 is slidably installed between the two slide grooves 52. Two screw rods 54 are rotatably connected to the mounting frame 51. The screw rods 54 are located in the slide grooves 52 and are threadedly connected to the CCD visual detector 53. A second motor 55 is installed on the mounting frame 51. The output shaft of the second motor 55 is connected to one of the screw rods 54. A belt transmission assembly 56 is arranged between the two screw rods 54. The CCD visual detector 53 and the second motor 55 are both electrically connected to the controller; under the action of the belt transmission assembly 56, the second motor 55 rotates alternately forward and reverse, which can drive the two screw rods 54 to rotate alternately forward and reverse, so that the CCD visual detector 53 moves forward and backward, so that the appearance and operation status panel of FTU0 are detected by the CCD visual detector 53.

[0032] like Figure 2 , Fig. 9 and Fig.11 As shown, it also includes an arc guide rail 61, a support frame 62, a grooved roller 63, a convex shaft 64, a rotating frame 65 and an electromagnet 66. The bottom of the mounting frame 51 is symmetrically connected to two arc guide rails 61. The mounting platform 1 is connected to a support frame 62, and the support frame 62 is located on the right side of the mounting seat 32. The grooved roller 63 is rotatably connected to the support frame 62. The groove on the side wall of the grooved roller 63 is a herringbone groove. The top of the mounting seat 32 is connected to a convex shaft 64, and the convex shaft 64 is slidably matched with the groove on the grooved roller 63. When the convex shaft 64 moves forward, the convex shaft 64 slides in the herringbone groove and drives the grooved roller 63 to rotate counterclockwise for a short distance through the herringbone groove, and then rotates clockwise for a long distance. The front side of the grooved roller 63 is connected to a rotating frame 65, and the rotating frame 65 is slidably connected to the arc guide rail 61. Two electromagnets 66 are connected to the rotating frame 65, and the electromagnet 66 can For the adsorption of the cabinet door of FTU0, the electromagnet 66 is electrically connected to the controller; when the mounting seat 32 drives the detection plug 33 to move forward, it can drive the convex shaft 64 to move forward, so that through the cooperation of the herringbone groove of the grooved roller 63, the rotating frame 65 drives the electromagnet 66 to rotate counterclockwise first, so that the electromagnet 66 moves downward and contacts the cabinet door of FTU0. At this time, the electromagnet 66 is energized to adsorb the cabinet door of FTU0, and then the rotating frame 65 drives the electromagnet 66 to rotate clockwise, thereby driving the cabinet door of FTU0 to rotate and open through the electromagnet 66, and when the mounting seat 32 moves backward, the rotating frame 65 drives the cabinet door of FTU0 to rotate counterclockwise and close through the electromagnet 66. At this time, the electromagnet 66 is powered off to release the cabinet door of FTU0, and then the rotating frame 65 drives the electromagnet 66 to move backward a proper distance to prevent the electromagnet 66 from hindering the movement of FTU0.

[0033] The mounting platform 1 is equipped with a detection system, and the CCD visual detector 53 is connected to the detection system. According to the connection socket structure of the FTU0 to be detected, a suitable detection plug 33 is selected, and the detection plug 33 is installed on the mounting seat 32, and the detection plug 33 is connected to the detection system;

[0034] The FTU0 to be inspected is placed on the two groups of support blocks 25 on the right side of the conveyor belt 22, and the tooling is started. The first motor 23 drives the conveyor belt 22 to operate, thereby driving the FTU0 to move to the left. At the same time, the conveyor belt 22 on the front side drives the detection block 35 to move. When one of the detection blocks 35 moves to the bottom of the infrared sensor 34, the infrared sensor 34 detects the detection block 35 and sends a signal. After receiving the signal, the controller controls the first motor 23 to stop running, and at the same time controls the electric push rod 31 to extend, so that the mounting seat 32 moves forward. The mounting seat 32 drives the contact wheel 411, the convex shaft 64, and the detection plug 33 to move forward. First, the contact wheel 411 cooperates with the wedge block 47 to make the clamping block 46 move toward each other to clamp and fix the FTU0. At the same time, the electromagnet 66 moves downward to contact the FTU0 cabinet door. At this time, the controller controls the electromagnet 66 to energize and adsorb the FTU0 cabinet door. As the mounting seat 32 continues to move forward, the clamping block 46 cannot continue to move. The contact wheel 411 squeezes the wedge block 47 to move downward. The first clamping block 49 cooperates with the second clamping block 410 to limit the position of the sliding frame 45, that is, to limit the position of the clamping block 46. At the same time, the rotating frame 65 drives the electromagnet 66 to rotate clockwise to open the FTU0 cabinet door, and the detection plug 33 will also be inserted into the socket of FTU0. In this way, through the movement of the mounting seat 32, the FTU0 is first clamped and fixed, and then the cabinet door is opened, and the detection plug 33 is inserted into FTU0 to prevent FTU0 from being displaced by force when the cabinet door is opened and the detection plug 33 is inserted, thereby affecting the continuation of the detection work; after the detection plug 33 is inserted into FTU0, the controller controls the second motor 55 and the CCD visual detector 53 to operate, and the second motor 55 rotates alternately forward and reversely to enable the CCD visual detector 53 to move forward and backward. The CCD visual detector 53 moves forward and backward to detect the appearance and operation status panel of FTU0, and the data connected to the detection plug 33 and the data of the CCD visual detector 53 can be transmitted to the detection system for processing, so that the detection of FTU0 can be realized;

[0035] After the detection is completed, the controller controls the CCD visual detector 53 to close, controls the second motor 55 to drive the CCD visual detector 53 to move and reset, and controls the electric push rod 31 to shorten, thereby driving the mounting seat 32 to move backward. The mounting seat 32 moves backward to first pull out the detection plug 33 from FTU0, and at the same time, the grooved roller 63 cooperates with the convex shaft 64 to make the rotating frame 65 rotate counterclockwise, thereby closing the cabinet door, and then the electromagnet 66 is powered off to release the FTU0 cabinet door, and at the same time, the contact wheel 411 also moves to the inclined position of the wedge block 47. As the mounting seat 32 continues to move backward, the clamping blocks 46 on the front and rear sides move in the opposite direction to release FTU0, and the rotating frame 65 also drives the electromagnet 66 to move upward and reset. After the electric push rod 31 is completely shortened and reset, the controller controls the first motor 23 to continue to operate, thereby driving FTU0 to continue to move to the left. In this way, the detection work of FTU0 can be completed quickly without manually plugging the detection plug 33, thereby improving work efficiency.

[0036] It should be noted that, during the inspection of an FTU0, a new FTU0 to be inspected can be placed on the support block 25 on the right side of the conveyor belt 22. In this way, when the conveyor belt 22 is running after the inspection of an FTU0 is completed, the FTU0 on the right side can be conveyed to the left to the inspection station, and the FTU0 that has completed the inspection can be moved to the left side of the conveyor belt 22. At this time, a FTU0 to be inspected can continue to be placed on the right side of the conveyor belt 22, and the FTU0 that has been inspected on the left side of the conveyor belt 22 can be taken out. In this way, the inspection work can be carried out continuously to improve the inspection efficiency.
