Description

Technical Field

[0001] The present invention relates to the technical field of ring main unit detection, and in particular to intelligent detection equipment for a ring main unit. Background Art

[0002] A ring main unit (RMU) is a set of electrical transmission and distribution equipment (high-voltage switchgear) housed in a metal or non-metallic insulated cabinet or assembled as a modular, compartmented ring main unit. It is primarily used to improve power supply reliability and control and protect the distribution system. The stable operation of the RMU is crucial to power supply reliability and safety, so RMU testing is essential.

[0003] The prior art discloses a Chinese patent with publication number CN 208060109 U: a sealing detection device for a gas-filled insulated ring network cabinet box, and discloses an air pump, an air pipe, a ventilation pipe and two pressure plates. By using the pressure plates to press the edge of the ring network cabinet box, the air pump inputs gas into the ventilation pipe through the air pipe, and the gas enters the ring network cabinet box through the ventilation pipe, thereby increasing the air pressure in the ring network cabinet box and detecting the sealing of the ring network cabinet box.

[0004] However, the above-mentioned existing technology still has certain defects, that is, during use, a pressure plate is used to press the edge of the ring network cabinet box, and the air pressure of the ring network cabinet box during the sealing test is reflected in the pressure gauge through a pressure sensor. This detection method cannot realize the sealing detection of the cable entry area at the lower end of the ring network cabinet, and the sealing test results cannot be quickly fed back during the inflation process.

DETAILED DESCRIPTION

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0047] The intelligent detection device of the present invention is a type of device for testing structural components, and is mainly used to detect the sealing of the cable entry area of the ring network cabinet, as well as the leakage point location and the discharge location inside the ring network cabinet entry room.

[0048] Example 1

[0049] Refer to the instruction manual Figures 1-4The present invention provides an intelligent detection device for a ring network cabinet, comprising a test body 1, a storage compartment 2 is provided at the rear side of the test body 1, a cover 3 is hingedly installed at one end of the storage compartment 2, wherein a lock assembly (not shown in the drawings) for locking and limiting the corresponding cover 3 of the test body 1 when the test body 1 is not in use can be further provided between the cover 3 and the test body 1. The lock assembly adopts the lock assembly used in the flip-type cabinet door in the prior art, which will not be described in detail here. Support plates 8 are fixed at both ends of the outer side of the cover 3, and a test part 4 is installed inside the storage compartment 2. The test part 4 consists of an incoming line detection assembly for detecting the sealing of the cable inlet of the ring network cabinet and a sealing assembly 411 for sealing the opening of the ring network cabinet;

[0050] The outside of the test body 1 is equipped with a load-bearing part 5 for placing the ring network cabinet to be tested. A docking component 6 is provided between the load-bearing part 5 and the test body 1. The load-bearing part 5 and the test body 1 can be detachably installed through the docking component 6. The detachable installation design between the load-bearing part 5 and the test body 1 can facilitate and quickly replace the load-bearing part 5.

[0051] It should be noted that the present invention uses the incoming line detection component and the sealing component 411 in combination to test the sealing of the incoming cable of the ring network cabinet and accurately locate the leakage point. When not in use, the test part 4 can be stored and packaged.

[0052] Specifically, if Figure 4-Figure 5 As shown, the test part 4 includes a bracket 41, a vertical plate 42 is fixedly provided at the bottom middle part of the bracket 41, and a cylinder 1 is fixedly provided on both sides of the vertical plate 42, wherein the telescopic end of one of the cylinders 1 is fixedly connected to the inner wall of the storage bin 2, wherein a slide groove can be opened on the inner side of the storage bin 2, and limiting blocks slidably connected to the inner part of the corresponding slide groove are installed on both sides of the bracket 41 to limit the extension amount of the bracket 41, and the incoming line detection component is installed at the telescopic end of the other cylinder 1, and a baffle 43 and a support plate 44 are fixedly provided on the top of the bracket 41, and a yaw assembly is provided between the baffle 43 and the support plate 44, wherein the baffle 43 is used to limit the swing angle of the yaw assembly, and the support plate 44 is used to support the yaw assembly;

[0053] The yaw assembly includes two ears 45 fixed to the top of the bracket 41 near the stop bar 43. A gear 1 46 driven by a servo motor is rotatably mounted between the two ears 45. A swing plate 47 is provided on the outside of the ears 45. A gear 2 48 meshing with gear 1 46 is fixedly mounted on the bottom of the swing plate 47. A seal assembly 411 is mounted on one side of the swing plate 47. A cylinder 2 is fixedly mounted on the side of the swing plate 47 away from the seal assembly 411 to push the seal assembly 411 to extend and retract.

[0054] The deflection assembly also includes an arc rod 49 fixed between the baffle 43 and the bracket 41 and a through hole 410 opened on the swing plate 47 corresponding to the arc rod 49. The arc rod 49 is movably arranged inside the corresponding through hole 410 to limit the deflection trajectory of the swing plate 47 and ensure that gear 1 46 and gear 2 48 are always in a state of meshing.

[0055] It should be noted that, in the process of testing the sealing performance of the cable inlet of the ring network cabinet, the ring network cabinet to be tested is mounted on the bearing portion 5, and the cylinder 1 connected to the storage bin 2 is started, and the extension of the cylinder 1 is used to push the bracket 41 carrying the deflection assembly out of the storage bin 2. When the bracket 41 is pushed out until the deflection assembly is completely exposed from the storage bin 2, the bracket 41 is stopped from being pushed out. At the same time, the servo motor is started to drive the gear 1 46 to rotate, and the meshing setting between the gear 1 46 and the gear 2 48 is used to use the rotating gear 1 46 to drive the pendulum plate 47 to swing upward along the arc rod 49 along with the gear 2 48 until the side of the pendulum plate 47 on which the sealing assembly 411 is installed is in contact with the baffle 43. At this time, the pendulum plate 47 is transformed from the initial state of being overlapped with the upper end of the support plate 44 to the state of being overlapped with the upper end of the support plate 44. Figure 4 The vertical state shown is then activated to push the sealing assembly 411 to seal the inlet of the ring main unit.

[0056] Specifically, if Figure 4-Figure 6 As shown, the sealing assembly 411 includes a sink 4111 opened on the surface of the swing plate 47, and a bottom plate 4112 fixedly connected to the telescopic end of the cylinder 2 is provided inside the sink 4111, and a panel 4114 is provided on one side of the bottom plate 4112. An annular airbag 4113 is fixedly provided between the bottom plate 4112 and the panel 4114, wherein the specifications of the bottom plate 4112 (herein referring to the length and width, the same below) are larger than the specifications of the inner side opening of the incoming room of the ring network cabinet to be tested, and the specifications of the panel 4114 are slightly smaller than the specifications of the inner side opening of the incoming room of the ring network cabinet to be tested. In this way, the inflated annular airbag 4113 and the bottom plate 4112 pressed against the incoming room of the ring network cabinet to be tested can be used to double-block the incoming room opening of the ring network cabinet to be tested, thereby preventing the gas filled into the incoming room from leaking from here;

[0057] The sealing assembly 411 also includes an air pump 4115 fixed on the surface of the swing plate 47. The air delivery end of the air pump 4115 is connected to a main air pipe 4116 that passes through the bottom plate 4112 and the panel 4114 in sequence. A secondary air pipe 4117 is provided between the main air pipe 4116 and the annular air bag 4113. Solenoid valves are installed on the main air pipe 4116 and the secondary air pipe 4117 for controlling the inflation status of the annular air bag 4113 and the incoming line chamber of the ring network cabinet to be tested.

[0058] It should be noted that in the process of sealing the incoming line chamber mouth of the ring network cabinet to be tested, after the sealing component 411 is pushed by cylinder 2 to seal the incoming line chamber mouth of the ring network cabinet, the air pump 4115 is started to fill the incoming line chamber with gas. During this period, the solenoid valves on the main air pipe 4116 and the auxiliary air pipe 4117 are in the open state. When the annular air bag 4113 is filled with gas to seal the incoming line chamber mouth, the solenoid valve on the auxiliary air pipe 4117 is closed to keep the annular air bag 4113 in a constant inflation state, and continue to fill gas into the sealed incoming line chamber, and then use the incoming line detection component to detect the sealing of the cable incoming area from the outside of the ring network cabinet.

[0059] Specifically, if Figure 7-Figure 9 and Figure 15 As shown, the incoming line detection component includes a mounting base 412 fixed to the telescopic end of the corresponding cylinder, a lifting groove and a driving groove are provided on the outer side of the mounting base 412, and a through groove 414 is provided between the lifting groove and the driving groove, a lifting frame 413 is slidably installed inside the lifting groove, a straight rack 415 is fixedly provided on the side of the lifting frame 413 facing the driving groove, a gear three 416 driven by a servo motor is provided inside the driving groove, the gear three 416 is meshed with the straight rack 415, and a linkage part 1 417 is provided inside the lifting frame 413, wherein the lifting groove is set to a cross structure, and a guide bar is provided on the side of the lifting frame 413 away from the straight rack 415, so as to utilize the guide bar, the straight rack 415 and the lifting frame 413 to form a cross lifting seat adapted to the cross-shaped lifting groove, and the meshing area of the gear three 416 and the straight rack 415 is to mesh with the straight rack 415 after passing through the through groove 414, so as to ensure that the lifting frame 413 can be lifted and lowered stably;

[0060] Specifically, the linkage member 417 includes three rotating shafts rotatably installed inside the lifting frame 413 and a sealing plate 1 fixed to the outside of the lifting frame 413. A horizontal worm is rotatably installed between the sealing plate 1 and the inner wall of the lifting frame 413. A fixed sleeve on the outer side of the horizontal worm is provided with a bevel gear 1. A fixed sleeve on the outer side of the rotating shaft arranged in the center is provided with a bevel gear 2 meshing with the bevel gear 1. The rotating shaft arranged in the center is driven to rotate by a driving motor installed on the inner side of the lifting frame 413. The outer sides of the rotating shafts at both ends are fixed with worm gears 1 meshing with the horizontal worm.

[0061] The incoming line detection assembly also includes a straight bar 418 fixedly sleeved on the outside of the rotating shaft at both ends, and an arc block 419 is fixedly provided at the end of the two straight bars 418. It can be achieved by controlling the forward and reverse rotation of the transverse worm to control the worm gear located on the outside of the rotating shaft at both ends to swing towards and away from each other, thereby controlling the arc blocks 419 at the ends of the two straight bars 418 to close and open. The inner sides of the two arc blocks 419 are provided with an arc path of T-shaped structure, and the insides of the two arc paths of T-shaped structure are both slidably connected with an arc bar 420, wherein the arc bar 420 and the arc path are both set to a T-shaped structure, which can effectively prevent the arc bar 420 from automatically separating from the arc path. The outer sides of the two arc bars 420 are provided with a plurality of tooth grooves 422 distributed at equal distances.

[0062] The outer sides of the two arc blocks 419 are provided with slots 421 connected to the arc paths of the corresponding T-shaped structures. The insides of the two slots 421 are both provided with gears 423 that mesh with the corresponding tooth grooves 422 through rotating rods. One of the gears 423 is driven to rotate by a servo motor installed on the outer side of the corresponding arc block 419. A locking member 424 is provided between the other gear 423 and the inner wall of the corresponding slot 421. The locking member 424 includes a straight rod fixed on the inner wall of the corresponding slot 421 and a movable member. The positioning cylinder, which is movable and sleeved at the bottom end of the outer side of the straight rod, also includes a concave spherical groove formed on the surface of the corresponding gear 423. A straight spring is sleeved on the outer side of the straight rod to securely connect the positioning cylinder to the inner wall of the corresponding groove 421. The bottom end of the positioning cylinder is also configured as a spherical structure that matches the concave spherical groove. The spherical surface on the positioning cylinder is larger than the spherical surface of the concave spherical groove (i.e., the positioning cylinder is only partially embedded in the concave spherical groove), so that the retaining member 424 does not affect the rotation of the corresponding gear 423.

[0063] An L-shaped seat 425 is fixedly provided on the inner middle part of one of the arc bars 420. A pendulum seat 426 driven by a servo motor is rotatably installed on the top of the L-shaped seat 425. A nozzle 427 is installed at one end of the pendulum seat 426. The liquid inlet end of the nozzle 427 is connected to the external soap liquid tank through a liquid supply pipe, and the soap liquid inside the soap liquid tank is supplied by a pump.

[0064] Furthermore, an infrared rangefinder is provided at the position of the centrally arranged rotating shaft on the outside of the lifting frame 413, which is used to detect the distance between the lifting frame 413 and the cable at the bottom end of the ring network cabinet to be detected, to ensure that the circle formed by the two arc bars 420 is concentric with the cable after closing. In addition, an image sensor is provided at the end of the swing seat 426, which is used to detect the location of the area where the cable inlet of the ring network cabinet is located, so that the soap solution can be accurately applied to the area.

[0065] It should be noted that in the process of testing the sealing of the cable inlet of the ring network cabinet, after the sealing assembly 411 is pushed by the cylinder 2 to seal the inlet chamber of the ring network cabinet, the corresponding cylinder 1 is used to push the mounting seat 412 toward the direction of the cable, and the advancement of the mounting seat 412 is controlled according to the signal fed back by the infrared rangefinder. After the advancement of the mounting seat 412 is stopped, the servo motor at the corresponding end is controlled to drive the centrally arranged rotating shaft to rotate, and the rotating bevel gear 1 is used to drive the horizontal worm to rotate, thereby driving the arc blocks 419 at the ends of the two straight bars 418 to close. When the two arc blocks 419 are completely closed, the corresponding gear 423 is driven to rotate by the servo motor at the corresponding position, thereby driving the corresponding arc bar 420 to move along the arc path of the T-shaped structure, and the other arc bar 420 will move synchronously under the push of the arc bar 420;

[0066] During the passive movement of the other arc bar 420, as the arc bar 420 moves passively, the spherical end of the positioning cylinder will be pushed out of the concave spherical groove thereon, and after the arc bar 420 that has passively moved returns to its position, the spherical end of the positioning cylinder will be inserted into the concave spherical groove again. In addition, during the movement of the arc bar 420 along the arc of the T-shaped structure, the L-shaped seat 425 installed on the inner side of the arc bar 420 will move synchronously. During this process, the swing seat 426 will swing under the drive of the corresponding servo motor, so that the nozzle 427 is facing the inspection object. In measuring the area of the cable inlet of the ring network cabinet, it is further necessary to explain that, in the process of using the nozzle 427 to spray the soap liquid to the designated area, it is also necessary to use the corresponding servo motor to drive the gear three 416 to rotate, so as to drive the lifting frame 413 to move along the lifting slot of the cross structure, so as to adjust the distance between the nozzle 427 and the soap liquid spraying area. After the soap liquid is sprayed, it is necessary to continue to control the movement of the arc bar 420 to judge whether the seal is good and the location of the sealing leakage point through the signal feedback from the image sensor;

[0067] The above-mentioned detection of the sealing of the cable inlet of the ring network cabinet is performed by using an image sensor to detect whether the soap film in the cable inlet area of the ring network cabinet generates bubbles, and the location of the sealing leak point can also be determined based on the location of the bubbles.
