Description

[Technical Field]

[0001] This invention relates to the technical field of intelligent inspection devices, and in particular to the technical field of an intelligent inspection device for a multifunctional detection-type enclosed switchgear. [Background Technology]

[0002] Enclosed switchgear is a complete power distribution device that integrates circuit breakers, disconnectors, enclosed busbar trunking, current transformers, and voltage transformers within a closed metal space. It is a common piece of equipment used in power systems for switching, controlling, and protecting electrical power during generation, transmission, distribution, and energy conversion. Existing enclosed switchgear is prone to loosening and overheating at copper busbars and cable joints due to seasonal changes, potentially leading to short circuits or even fires. Partial discharge may also occur in some components. Therefore, to ensure the normal operation of the power system, maintenance personnel need to conduct regular inspections of the switchgear to guarantee normal power supply.

[0003] However, existing enclosed switchgear, due to its high integration and enclosure, is inconvenient to switch on and off, and for safety reasons, its doors cannot be opened while powered on. This prevents maintenance personnel from performing inspections and maintenance without interrupting power or opening the doors. However, opening the doors during a power outage disrupts the normal power supply to residents and businesses, and also prevents maintenance personnel from checking the heat levels of various connections while the switchgear is in operation, making troubleshooting difficult, inaccurate, and prone to missed faults.

[0004] Therefore, inspection robots that are directly installed inside switchgear have gradually appeared on the market, such as the intelligent switchgear inspection robot with application number CN201910309583.9. This device includes straight rails, curved rails, vertical rails, a railcar, a base, a climbing mechanism, a spherical working head, a motion controller, and a detector. The straight rails are horizontally fixed above the switchgear according to the switchgear layout inside the switchgear room. The curved rails connect two sections of straight rails. T-slots are machined on the lower surfaces of both the straight and curved rails. The railcar is engaged in the T-slots. The vertical rail is fixed to the lower part of the railcar. The climbing mechanism is installed in the base and engaged with the vertical rail. The motion controller is connected to the railcar and the climbing mechanism. The spherical working head is hinged to the bottom of the base. The detector is installed inside the spherical working head and can complete vertical lifting and lowering via the vertical rail. It can drive the detector to inspect different height parts of the switchgear, improving the accuracy and completeness of the inspection and ensuring the stable operation of the switchgear. However, the aforementioned intelligent inspection robot must perform inspections along a fixed route using a fixed rigid track. Since the size and internal wiring of switch cabinets are usually different, the same rigid track is difficult to adapt to different switch cabinets, which in turn causes trouble for the installation of the intelligent inspection robot. [Summary of the Invention]

[0005] The purpose of this invention is to solve the problems in the prior art and to propose a multifunctional intelligent inspection device for enclosed switchgear, which can inspect enclosed switchgear without interrupting power or opening the cabinet, and can adapt to a variety of different enclosed switchgear.

[0006] To achieve the above objectives, this invention proposes a multifunctional detection-type intelligent inspection device for enclosed switchgear, comprising a sliding table, an electric telescopic device, a steering motor, an infrared detector, a smoke detector, a current detector, a voltage detector, and a controller. The sliding table is installed on the inner wall of the enclosed switchgear. The electric telescopic device, driven by the sliding table, slides along a designated route on the inner wall of the enclosed switchgear. The steering motor, driven by the electric telescopic device, moves closer to or away from the inner wall of the enclosed switchgear. The infrared detector, driven by the steering motor, rotates and performs thermal imaging detection of the inner cavity of the enclosed switchgear. Several smoke detectors are installed in the inner cavity of the enclosed switchgear to detect smoke concentration. Several current detectors and voltage detectors are connected to... The circuit of the enclosed switchgear is used for current and voltage detection. The controller is electrically connected to the slide table, electric telescopic device, steering motor, infrared probe, smoke detector, current detector and voltage detector and is also connected to the base station for communication. The slide table includes a flexible slide rail, a slider and a sliding driver. The flexible slide rail can be bent and twisted freely and is provided with a slide track. A set of sliding drivers is provided at each end of the slide track. The sliding driver includes a sliding motor, a spool and a traction line. The output shaft of the sliding motor is coaxially connected to the spool. One end of the traction line is fixed to the wall of the spool and the other end extends into the slide track after winding around the wall of the spool several times and is connected to the slider. The slider can be driven by the two sets of sliding drivers to move along the slide track.

[0007] Preferably, the flexible slide rail is a silicone or rubber slide rail.

[0008] Preferably, the traction line is located in the groove of the slide, and the opening of the groove is provided with several baffles to prevent the traction line from leaving the groove.

[0009] Preferably, the slider includes a block body and movable plugs. The width of the block body is smaller than the width of the slide. Several movable plugs are respectively arranged on both sides of the long side of the block body. Each movable plug includes a guide post, a ball, and a spring. One end of the guide post extends into a recess in the block body, while the other end is rotatably connected to the ball. The spring is located in the recess, and both ends are fixed to the block body and the guide post, respectively.

[0010] Preferably, the slider further includes a limiting mechanism, and several limiting mechanisms are respectively arranged on both sides of the long side of the block body. The limiting mechanism includes a screw and a nut. The side plate of the flexible slide rail is provided with a through groove along the length direction. One end of the screw is screwed into the screw hole of the slider and the other end passes through the through groove. Two nuts are respectively arranged on the inner and outer sides of the side plate and are threaded to the outside of the screw.

[0011] Preferably, the electric telescopic device includes a support plate, a telescopic motor, support blocks, a lead screw, a lead nut, a support rail, support rods, and a seat plate. Two support blocks are respectively installed on the same side of the support plate. The lead screw is rotatably connected between the two support blocks and driven to rotate by the telescopic motor. The lead nut is threaded to the outside of the lead screw and is slidably connected to the support rail fixed on the support plate. The middle parts of the two support rods are hinged together to form an X-hinged unit. The ends of several sets of X-hinged units are sequentially hinged to form a scissor-type telescopic component. The free ends of the two support rods at one end of the scissor-type telescopic component are respectively hinged to the lead nut and one of the support blocks. The free ends of the two support rods at the other end of the scissor-type telescopic component are respectively hinged to the seat plate. The support plate and the seat plate are respectively fixed to the slide table and the steering motor.

[0012] The beneficial effects of this invention are:

[0013] This invention utilizes a sliding table, an electric telescopic device, a steering motor, an infrared probe, and a controller. The sliding table is constructed from a flexible slide rail, a slider, and a sliding actuator. The flexible slide rail can be freely bent and twisted as needed, allowing the infrared probe to travel along a specific route within the enclosed switchgear. The electric telescopic device and steering motor adjust the distance and detection angle between the infrared probe and each detection point, ensuring the accuracy of thermal imaging detection. Simultaneously, smoke detectors, current detectors, and voltage detectors can be used to detect smoke, current, and voltage respectively, assisting in determining whether the enclosed switchgear is operating normally. This eliminates the need for power outages and opening the cabinet for inspection, avoiding the inconvenience and hassle of power outages and cabinet opening. Furthermore, by incorporating a wire trough within the sliding track and at the opening of the wire trough… Several baffles are installed to effectively prevent the traction line from tangling or obstructing during operation, ensuring smooth pulling of the slider. Several movable plugs are installed on both sides of the long side of the block body, and the movable plugs are composed of guide posts, balls, and springs. The springs provide cushioning, effectively preventing the block body from colliding with the inner wall of the slideway when it moves and turns along the slideway. At the same time, the rotating ball also reduces the friction between the block body and the slideway, further ensuring the smoothness of the block body's sliding. Several limiting mechanisms are installed on both sides of the long side of the block body, and the limiting mechanisms are composed of screws and nuts. The distance between the two nuts set on the inner and outer sides of the side plate can be used to control the range of lateral movement of the slider in the slideway.

Detailed Implementation Methods

[0020] See Figures 1 to 4This invention discloses a multifunctional detection-type intelligent inspection device for enclosed switchgear, comprising a sliding table 1, an electric telescopic device 2, a steering motor 3, an infrared detector 4, a smoke detector, a current detector, a voltage detector, and a controller. The sliding table 1 is installed on the inner wall of the enclosed switchgear. The electric telescopic device 2, driven by the sliding table 1, slides along a designated route on the inner wall of the enclosed switchgear. The steering motor 3, driven by the electric telescopic device 2, moves closer to or further away from the inner wall of the enclosed switchgear. The infrared detector 4, driven by the steering motor 3, rotates and performs thermal imaging detection of the inner cavity of the enclosed switchgear. Several smoke detectors are installed in the inner cavity of the enclosed switchgear to detect smoke concentration. Several current and voltage detectors are connected to the wiring of the enclosed switchgear to detect current and voltage, respectively. The controller is electrically connected to the slide table 1, the electric telescopic device 2, the steering motor 3, the infrared detector 4, the smoke detector, the current detector, and the voltage detector, and is also communicatively connected to the base station. The slide table 1 includes a flexible slide rail 11, a slider 12, and a sliding driver 13. The flexible slide rail 11 can be freely bent and twisted and is provided with a slide track. A set of sliding drivers 13 is provided at each end of the slide track. The sliding driver 13 includes a sliding motor 131, a bobbin 132, and a traction line 133. The output shaft end of the sliding motor 131 is coaxially connected to the bobbin 132. One end of the traction line 133 is fixed to the wall of the bobbin 132, and the other end extends into the slide track after winding around the wall of the bobbin 132 several times and is connected to the slider 12. The slider 12 can be driven by the two sets of sliding drivers 13 to move along the slide track.

[0021] The flexible slide rail 11 is a silicone or rubber slide rail.

[0022] The chute 111 is located in the traction line 133. The opening of the chute 111 is provided with several baffles 112 to prevent the traction line 133 from leaving the chute 111.

[0023] The slider 12 includes a block body 121 and movable plugs 122. The width of the block body 121 is smaller than the width of the slide. Several movable plugs 122 are respectively arranged on both sides of the long side of the block body 121. Each movable plug 122 includes a guide post 1221, a ball 1222, and a spring 1223. One end of the guide post 1221 extends into a recess in the block body 121, and the other end is rotatably connected to the ball 1222. The spring 1223 is located in the recess, and both ends are fixed to the block body 121 and the guide post 1221, respectively.

[0024] The slider 12 also includes a limiting mechanism 123. Several limiting mechanisms 123 are respectively arranged on both sides of the long side of the block body 121. The limiting mechanism 123 includes a screw 1231 and a nut 1232. The side plate of the flexible slide rail 11 is provided with a through groove 113 along the length direction. One end of the screw 1231 is screwed into the screw hole of the slider 12 and the other end is set through the through groove 113. Two nuts 1232 are respectively arranged on the inner and outer sides of the side plate and are threaded to the outside of the screw 1231.

[0025] The electric telescopic device 2 includes a support plate 21, a telescopic motor 22, support blocks 23, a lead screw 24, a lead screw nut 25, a support rail 26, support rods 27, and a seat plate 28. Two support blocks 23 are respectively installed on the same side of the support plate 21. The lead screw 24 is rotatably connected between the two support blocks 23 and is driven to rotate by the telescopic motor 22. The lead screw nut 25 is threaded to the lead screw 24 and is slidably connected to the support rail 26 fixed on the support plate 21. The middle parts of the two support rods 27 are hinged to form an X-hinged unit. The ends of several sets of X-hinged units are hinged sequentially to form a scissor-type telescopic component. The free ends of the two support rods 27 at one end of the scissor-type telescopic component are respectively hinged to the lead screw nut 25 and one of the support blocks 23. The free ends of the two support rods 27 at the other end of the scissor-type telescopic component are respectively hinged to the seat plate 28. The support plate 21 and the seat plate 28 are respectively fixed to the slide table 1 and the steering motor 3.

[0026] The working process of this invention:

[0027] First, the flexible slide rail 11 is bent or twisted into an S-shape, C-shape, or U-shape as needed, and then fastened to the inner wall of the enclosed switch cabinet. Next, the distance between the two nuts 1232 located on the screw 1231 is adjusted according to the degree of bending or twisting of the flexible slide rail 11.

[0028] During operation, the sliding motors 131 of the two sets of sliding actuators 13 drive the reel 132 to rotate, enabling wire feeding or retraction. This, in turn, uses the traction line 133 to move the slider 12 and its connected components along the track. Simultaneously, the telescopic motor 22 drives the lead screw 24 to rotate, causing the lead nut 25 to move along the lead screw 14. This telescopic movement of the scissor-type telescopic component moves the steering motor 3 and the infrared sensor 4 closer to or further away from the inner wall of the enclosed switchgear. Furthermore, the steering motor 3 can also synchronously drive the infrared sensor 4 to rotate, allowing it to perform thermal imaging detection on each joint along a specific route, preventing accidents such as fires caused by localized overheating or discharge. In addition, the smoke detector, current detector, and voltage detector can also detect smoke, current, and voltage in real time, respectively, to assist in determining whether the enclosed switchgear is operating normally.

[0029] This invention utilizes a sliding table, an electric telescopic device, a steering motor, an infrared probe, and a controller. The sliding table is constructed from a flexible slide rail, a slider, and a sliding actuator. The flexible slide rail can be freely bent and twisted as needed, allowing the infrared probe to travel along a specific route within the enclosed switchgear. The electric telescopic device and steering motor adjust the distance and detection angle between the infrared probe and each detection point, ensuring the accuracy of thermal imaging detection. Simultaneously, smoke detectors, current detectors, and voltage detectors can be used to detect smoke, current, and voltage respectively, assisting in determining whether the enclosed switchgear is operating normally. This eliminates the need for power outages and opening the cabinet for inspection, avoiding the inconvenience and hassle of power outages and cabinet opening. Furthermore, by incorporating a wire trough within the sliding track and at the opening of the wire trough… Several baffles are installed to effectively prevent the traction line from tangling or obstructing during operation, ensuring smooth pulling of the slider. Several movable plugs are installed on both sides of the long side of the block body, and the movable plugs are composed of guide posts, balls, and springs. The springs provide cushioning, effectively preventing the block body from colliding with the inner wall of the slideway when it moves and turns along the slideway. At the same time, the rotating ball also reduces the friction between the block body and the slideway, further ensuring the smoothness of the block body's sliding. Several limiting mechanisms are installed on both sides of the long side of the block body, and the limiting mechanisms are composed of screws and nuts. The distance between the two nuts set on the inner and outer sides of the side plate can be used to control the range of lateral movement of the slider in the slideway.

[0030] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
