Description

Technical Field

[0001] This invention relates to the field of inspection robot technology, specifically to an intelligent inspection robot. Background Technology

[0002] Intelligent inspection robots rely on machine vision, sensor detection, and autonomous mobility technologies. They are widely used in high-risk, high-frequency, and repetitive inspection scenarios such as power substations, chemical plants, rail transit, and computer room maintenance. By being equipped with intelligent detection modules such as image acquisition, infrared temperature measurement, and gas sensing, they can automatically collect equipment status, identify defects, and provide early warnings of anomalies. They can effectively replace manual labor in completing high-intensity, high-risk, and routine inspection tasks. They are core automated equipment in the industrial intelligent operation and maintenance system and have extremely high engineering application value.

[0003] However, existing traditional robot detection devices and bases generally adopt a multi-bolt fixed assembly structure, which relies on manual disassembly and calibration. There is no intelligent assembly mechanism for rapid alignment and self-locking adaptation. Equipment maintenance, sensor calibration, and functional module switching procedures are cumbersome, time-consuming, and inefficient. At the same time, traditional equipment relies solely on manual dust cover protection, which depends on human judgment and operation. This results in problems such as cumbersome operation, easy omissions, and delayed protection. It is also inconvenient to intelligently switch ventilation and dust protection states according to the module assembly and disassembly conditions, resulting in insufficient autonomous protection capabilities of the equipment.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

A transmission gear is fixedly sleeved on the outer surface of the plug-in tube, and teeth are fixedly connected to the outer surface of the rotating block. A plug-in rod is fixedly connected to the bottom of the detection box at the position corresponding to the plug-in tube.

[0007] Preferably, the protective component includes abutment blocks fixedly connected to the top two surfaces of the robot dog on the base, and abutment rods slidably limited on both sides of the abutment blocks in the bottom cavity of the detection box, with a push block fixedly connected to the end of the abutment rod away from the abutment block; A limiting plate is fixedly connected to the inner wall of the detection chamber behind the cooling fan. A protective blade is rotatably connected to the inner side of the limiting plate. An adjusting rod is rotatably connected to the outer surface of the limiting plate. A movable plate is provided on the side end of the limiting plate. One end of the adjusting rod is fixedly connected to the rotation shaft of the protective blade, and the other end is rotatably connected to the surface of the movable plate. A push rod is fixedly connected to the bottom of the movable plate.

[0008] Preferably, the ratchet gear and the pawl mesh with each other, and the teeth are evenly arranged in several groups on the outer surface of the rotating block, and the several groups of teeth mesh with the tooth surface of the transmission gear.

[0009] Preferably, an electromagnet is fixedly connected to the back end of the pawl on the inner wall of the rotating block, and the electromagnet attracts the back end of the pawl when energized.

[0010] Preferably, four sets of plug-in cylinders are evenly arranged around the periphery of the rotating block, and a through groove is provided on the top of the base robot dog corresponding to the plug-in rod, with the through groove communicating with the top of the plug-in cylinder.

[0011] Preferably, a guide groove is provided on the inner wall of the plug-in cylinder, and a guide rod is fixedly connected to the bottom periphery of the plug-in rod. The guide groove is spirally opened along the inner wall of the plug-in cylinder, and the guide rod is limited and slidable within the guide groove.

[0012] Preferably, the base of the robot dog has grooves at both the front and rear ends of its top, and a pre-tightening plate is vertically limited and slidable in the groove. A first spring is fixedly connected to the bottom of the pre-tightening plate, and the other end of the first spring is fixedly connected to the inner wall of the bottom end of the groove.

[0013] Preferably, the cross-section of the contact block is set as an isosceles trapezoid, the contact surface of the push block is set as an inclined structure, a second spring is sleeved on the surface of the contact rod, and a third spring is sleeved on the surface of the push rod located in the bottom cavity of the detection box.

[0014] Preferably, the protective blades are arranged in several groups at equal vertical intervals on the inner side of the limiting plate, and the adjusting rod is configured as an "L" shaped structure.

[0015] Preferably, the push rod extends into the bottom cavity of the detection box and abuts against the surface of the push block.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention comprises a fixed block, a rotating block, a ratchet, a pawl, a connector, a transmission gear, teeth, and a connector rod. The connector rod, in conjunction with a spiral guide groove, enables the rotational transmission of the connector. A one-way self-locking structure is formed by the ratchet and pawl. During assembly, mechanical guidance ensures automatic alignment and tightening. During disassembly, an electromagnet, when energized, attracts the pawl, overcoming the torsion spring force to disengage from the ratchet, allowing for reverse release. The structure is simple and the operation is reliable. Compared to traditional bolt-fixed structures, it allows for rapid disassembly and replacement of the inspection box without the need for auxiliary tools, effectively simplifying assembly and maintenance processes. The pre-tightening plate elastically tightens and eliminates assembly gaps, preventing installation loosening and module misalignment caused by robot vibration, ensuring stable and reliable inspection.

[0017] 2. This invention comprises an abutment block, an abutment rod, a push block, a limiting plate, protective blades, an adjusting rod, a moving plate, and a pushing rod. Utilizing the mechanical stroke of the testing housing assembly and downward pressure, a purely mechanical linkage transmission structure is formed through the abutment block, push block, pushing rod, and adjusting rod. When the testing housing is assembled and locked, the protective blades automatically flip open, opening the heat dissipation duct and cooperating with the cooling fan to force heat dissipation of the internal testing components, reducing the module's operating temperature. When the testing housing is disassembled and removed, the springs automatically reset, causing the protective blades to close and seal the air duct openings. Through the coordinated operation of the assembly state and the dustproof and heat dissipation structure, the "installation ventilation and heat dissipation, disassembly closure and dust prevention" working conditions are automatically switched, eliminating the need for manual opening and closing. This effectively prevents dust and water mist from entering the air duct and causing blockages during idle periods, continuously ensuring unobstructed heat dissipation and stable heat dissipation.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8 The present invention provides a technical solution: an intelligent inspection robot, including a base robot dog 1, a detection box 2 on the top of the base robot dog 1, a visual detection module 3 installed at one end of the top of the detection box 2, an environmental perception module 4 installed at the other end of the top of the detection box 2, a cooling fan 5 installed on the side wall of the detection box 2, an assembly mechanism installed inside the base robot dog 1, and a protective component installed at the bottom of the detection box 2. When this intelligent inspection robot is working, it relies on the base robot dog 1 to achieve autonomous mobile inspection in all terrains. Through the visual inspection module 3 and environmental perception module 4 mounted on the top inspection box 2, it can simultaneously complete intelligent inspection operations such as on-site image acquisition and environmental parameter detection. At the same time, the assembly mechanism can realize the automatic and rapid locking and fixing of the inspection box 2 and the base robot dog 1. The assembly mechanism includes a fixed block 61 fixedly connected to the inner wall of the top cavity of the base robot dog 1. A rotating block 62 is rotatably connected to the inner wall of the top cavity of the base robot dog 1 corresponding to the fixed block 61. The top of the fixed block 61 extends into the interior of the rotating block 62 and is fixedly connected to a ratchet 63. A pawl 64 is rotatably connected to the inner wall of the rotating block 62 around the ratchet 63 via a torsion spring. The ratchet 63 and the pawl 64 mesh with each other. An electromagnet 10 is fixedly connected to the back end of the pawl 64 on the inner wall of the rotating block 62. Several sets of teeth 67 are evenly arranged circumferentially on the outer surface of the rotating block 62. Several sets of teeth 67 mesh with the tooth surface of the transmission gear 66. The plug rod 68 at the bottom of the detection box 2 is aligned with the through slot at the top of the base robot dog 1 and pressed vertically downwards. The guide rod 9 fixed at the bottom of the plug rod 68 slides along the spiral guide groove 8 on the inner wall of the plug cylinder 65. The vertical downward displacement of the plug rod 68 is converted into the circumferential rotation of the plug cylinder 65 by the guiding effect of the spiral guide groove. During the rotation of the plug cylinder 65, the transmission gear 66 fixedly sleeved on its periphery meshes with the multiple sets of teeth 67 arranged circumferentially on the outer side of the rotating block 62, thereby driving the rotating block 62 to rotate synchronously. Among them, the fixed block 61 is fixed and the ratchet 63 on its top remains stationary. When the rotating block 62 rotates with the assembly action, the pawl 64 inside it, which is hinged by a torsion spring, continuously slides elastically against the tooth surface of the ratchet 63. By utilizing the one-way meshing characteristic of the ratchet 63 and the pawl 64, the rotating block 62 can only rotate in one direction along the assembly locking direction and is locked in the opposite direction, thereby realizing the automatic tightening of the plug rod 68 and the plug cylinder 65.

[0022] A plug-in cylinder 65 is rotatably connected to the outer wall of the rotating block 62 at the top of the base robot dog 1. A transmission gear 66 is fixedly sleeved on the outer surface of the plug-in cylinder 65. Teeth 67 are fixedly connected to the outer surface of the rotating block 62. A plug-in rod 68 is fixedly connected to the bottom of the detection box 2 at the position corresponding to the plug-in cylinder 65. Grooves are opened at the front and rear ends of the top of the base robot dog 1. A pre-tightening plate 11 is vertically limited and slidable in the groove. A first spring is fixedly connected to the bottom of the pre-tightening plate 11. The other end of the first spring is fixedly connected to the inner wall of the bottom end of the groove. A guide groove 8 is opened on the inner wall of the plug-in cylinder 65. A guide rod 9 is fixedly connected to the outer periphery of the bottom end of the plug-in rod 68. The guide groove 8 is opened in a spiral shape along the inner wall of the plug-in cylinder 65. The guide rod 9 is limited and slidable in the guide groove 8. Four sets of plug-in cylinders 65 are evenly arranged around the outer periphery of the rotating block 62. A through groove is opened at the top of the base robot dog 1 corresponding to the plug-in rod 68. The through groove is interconnected with the top of the plug-in cylinder 65.

[0023] As one embodiment of the present invention, the protective component includes abutment blocks 71 fixedly connected to the top two surfaces of the base robot dog 1, and abutment rods 72 slidably limited on both sides of the abutment blocks 71 in the bottom cavity of the detection box 2. The end of the abutment rods 72 away from the abutment blocks 71 is fixedly connected to a push block 73. The cross section of the abutment block 71 is set as an isosceles trapezoidal structure, the abutment surface of the push block 73 is set as an inclined structure, and a second spring is sleeved on the surface of the abutment rods 72. A limiting plate 74 is fixedly connected to the inner wall of the detection chamber 2 behind the cooling fan 5. A protective blade 75 is rotatably connected to the inner side of the limiting plate 74. An adjusting rod 76 is rotatably connected to the outer surface of the limiting plate 74. A movable plate 77 is provided at the side end of the limiting plate 74. One end of the adjusting rod 76 is fixedly connected to the rotation shaft of the protective blade 75, and the other end is rotatably connected to the surface of the movable plate 77. A push rod 78 is fixedly connected to the bottom of the movable plate 77. The push rod 78 extends into the bottom cavity of the detection chamber 2 and abuts against the surface of the push block 73. Several sets of protective blades 75 are vertically and equidistantly arranged inside the limiting plate 74. The adjusting rod 76 is set with an "L" shaped structure. A third spring is sleeved on the surface of the push rod 78 located in the bottom cavity of the detection chamber 2. The isosceles trapezoidal contact blocks 71 fixed on both sides of the top of the base robot dog 1 gradually press against the contact rod 72 inside the bottom of the detection box 2, causing it to slide laterally and compress the second spring. The lateral sliding of the contact rod 72 drives the push block 73 to move, and the push block 73 simultaneously drives the push rod 78 to move vertically. The push rod 78 drives the moving plate 77 to move. During the movement of the moving plate 77, the "L"-shaped adjusting rod 76 is pulled to rotate. The other end of the adjusting rod 76 is fixedly connected to the rotation shaft of the protective blade 75, which in turn drives the multiple sets of vertically equidistant protective blades 75 inside the limiting plate 74 to flip and open synchronously, fully opening the air duct behind the cooling fan 5.

[0024] Working Principle: When this intelligent inspection robot is working, it relies on the base robot dog 1 to achieve autonomous all-terrain mobile inspection. Through the vision detection module 3 and environmental perception module 4 mounted on the top detection box 2, it simultaneously completes intelligent inspection operations such as on-site image acquisition and environmental parameter detection. At the same time, the assembly mechanism realizes the automatic and rapid locking and fixing of the detection box 2 and the base robot dog 1. During the assembly operation, the plug rod 68 at the bottom of the detection box 2 is aligned with the through slot at the top of the base robot dog 1 and pressed vertically downward. The guide rod 9 fixed at the bottom of the plug rod 68 slides along the spiral guide groove 8 on the inner wall of the plug cylinder 65. Using the guiding effect of the spiral guide groove, the vertical downward displacement of the plug rod 68 is converted into the circumferential rotation of the plug cylinder 65. During the rotation of the plug cylinder 65, the transmission gear 66 fixedly sleeved on its periphery meshes with the multiple sets of teeth 67 arranged circumferentially on the outer side of the rotating block 62, thereby driving the rotating block 62 to rotate synchronously. Among them, the fixed block 61 is fixed and the ratchet 63 on its top remains stationary. When the rotating block 62 rotates with the assembly action, the pawl 64 inside it, which is hinged by a torsion spring, continuously slides elastically against the tooth surface of the ratchet 63. Utilizing the one-way meshing characteristic of the ratchet 63 and the pawl 64, the rotating block 62 can only rotate in one direction along the assembly locking direction and is locked in the opposite direction. This enables the automatic tightening of the plug rod 68 and the plug cylinder 65, completing the rapid assembly and fixing of the detection box 2. At the same time, the front and rear ends of the top of the base robot dog 1 are provided with vertically sliding pre-tightening plates 11. Under the elastic force of the first spring at the bottom, the pre-tightening plates 11 always elastically press against the bottom of the detection box 2, automatically compensating for mechanical assembly gaps, effectively eliminating loosening and displacement caused by robot walking and obstacle crossing vibrations, and ensuring that the detection box 2 is installed stably. When disassembly, maintenance, or replacement is required, the control electromagnet 10 is energized. The electromagnet 10 generates an attraction force that overcomes the torsion spring force, attracting the pawl 64 inward and retracting it, so that the pawl 64 and the ratchet gear 63 are completely disengaged, releasing the overall one-way locking limit. With the push action of the pre-tightening plate 11, the rotating block 62 and the plug-in cylinder 65 can rotate freely in the opposite direction. With the guide return structure of the spiral guide groove 8, the test box 2 can be directly taken out upward, realizing tool-free, fast, and non-destructive disassembly. During the pressing and locking process of the detection box 2, the isosceles trapezoidal contact blocks 71 fixed on both sides of the top of the base robot dog 1 gradually press the contact rod 72 inside the bottom of the detection box 2 to slide laterally and compress the second spring; the lateral sliding of the contact rod 72 drives the push block 73 to move, and the push block 73 simultaneously drives the push rod 78 to move vertically, and the push rod 78 drives the moving plate 77 to move. During the movement of the moving plate 77, the "L"-shaped adjusting rod 76 is pulled to rotate. The other end of the adjusting rod 76 is fixedly connected to the rotating shaft of the protective blade 75, which in turn drives the multiple sets of vertically equidistant protective blades 75 inside the limiting plate 74 to flip and open synchronously, fully opening the air duct behind the cooling fan 5, so that the cooling fan 5 can form a stable convection air duct when it is working, continuously performing forced air cooling on the internal circuit components and quickly removing the working heat.

[0025] When the detection box 2 is disassembled and separated from the base robot dog 1, the squeezing force between the abutment block 71 and the push block 73 on the top of the base completely disappears. The abutment rod 72 automatically resets under the rebound of the second spring, and the push rod 78 and the moving plate 77 return to their original positions synchronously under the elastic reset of the third spring. This drives the "L"-shaped adjusting rod 76 to rotate in the opposite direction, causing multiple sets of protective blades 75 to rotate and close synchronously, completely sealing the ventilation vents of the cooling fan 5. It can automatically switch working conditions according to the assembly status, realizing the intelligent linkage effect of automatic window opening for ventilation and heat dissipation during assembly and automatic window closing for dust prevention during disassembly and separation. This effectively prevents external dust, water mist, and impurities from entering the cooling duct.
