Description

Technical Field

[0001] The utility model relates to the technical field of inspection robots, and particularly relates to an intelligent inspection robot for a thermal power plant. Background Art

[0002] A thermal power plant, abbreviated as a thermal power station, is a factory that uses combustibles (such as coal) as fuel to produce electric energy. Its basic production process is as follows: the fuel heats water to generate steam during combustion, converting the chemical energy of the fuel into heat energy. The steam pressure drives the steam turbine to rotate, converting heat energy into mechanical energy. Then the steam turbine drives the generator to rotate, converting mechanical energy into electric energy. When monitoring the electrical operation of a thermal power plant, an inspection robot is required for monitoring.

[0003] An inspection robot uses a mobile robot as a carrier, visible light cameras, infrared thermal imagers, and other detection instruments as a load system, and a multi-field information fusion of machine vision - electromagnetic field - GPS - GIS as a navigation system for the robot's autonomous movement and autonomous inspection, and an embedded computer as a software and hardware development platform for the control system. It has functions such as obstacle detection, recognition and positioning, autonomous operation planning, autonomous obstacle crossing, autonomous inspection of transmission lines and their line corridors, automatic storage and remote wireless transmission of inspection images and data by the robot body, ground remote wireless monitoring and remote control, on-line real-time power supply, background inspection operation management and analysis and diagnosis.

[0004] Chinese patent document CN216682196U discloses a coal trestle intelligent inspection robot, including a track and a robot body arranged on the track. The top of the robot body is provided with 4 walking wheels, and a driving motor and a controller are installed inside the robot body to drive the walking wheels. The walking wheels are hung on the track. The upper end of a lifting arm is fixedly installed at the bottom of the robot body, and a dual-view pan-tilt is installed at the lower end of the lifting arm. An obstacle avoidance ultrasonic wave and a gas sensor are arranged on the front wall of the robot body. A high-definition camera and an infrared thermal imager are fixedly installed at the bottom of the dual-view pan-tilt, and a pick-up microphone is arranged below the infrared thermal imager. Through the technical solution of the above patent document, the inspection without dead angles and blind spots is maximally realized, achieving unmanned or less-manned operation of the coal conveying trestle, liberating the labor intensity of production personnel and management personnel, and enabling personnel to be freed from repetitive and inefficient labor and engage in more advanced analysis and management work.

At the four corners of the lower end of the outer surface of the box body 1, support legs 2 are fixedly connected. At the lower ends of the outer surfaces of the four support legs 2, universal wheels 3 are fixedly connected. At the front and rear ends of the outer surface of the box body 1, ventilation mechanisms 4 are symmetrically and fixedly connected, which can make the inner cavity of the box body 1 have good air permeability. At the left and right ends of the outer surface of the box body 1, heat dissipation mechanisms 5 are symmetrically and fixedly connected, which can extract the heat in the inner cavity of the box body 1 to the outside. On the right part of the bottom wall of the inner cavity of the box body 1, a driving motor 1 is fixedly connected. The upper piston rod output end of the driving motor 1 is fixedly connected with a gear 1. In the middle of the bottom wall of the inner cavity of the box body 1, a transmission mechanism 7 is fixedly connected, which can drive the detection component 10 to rotate horizontally. In the middle of the upper end of the outer surface of the box body 1, a support mechanism 8 is fixedly connected, which can support and fix the bearing mechanism 9. The upper part of the support mechanism 8 is fixedly connected with a bearing mechanism 9, which can bear the detection component 10. The upper part of the bearing mechanism 9 is rotatably connected with a detection component 10, which can detect the thermal power plant. An electric motor 11 is fixedly installed on the upper side of the front part of the detection component 10.

[0025] To achieve the purpose of making the inner cavity of the box body 1 have good air permeability, refer to Figure 2 , the ventilation mechanism 4 includes a rectangular frame 41. In the middle of the rectangular frame 41, a number of ventilation holes 42 communicating with the outside are arranged at intervals, which can make the inner cavity of the box body 1 communicate with the outside gas.

[0026] To achieve the purpose of extracting the heat in the inner cavity of the box body 1 to the outside, refer to Figure 2 , the heat dissipation mechanism 5 includes a circular frame 51. In the middle of the inner cavity of the circular frame 51, a fan 52 is rotatably connected, which can timely discharge the heat generated in the inner cavity of the box body 1 to the outside.

[0027] To achieve the purpose of driving the detection component 10 to rotate horizontally, refer to Figure 3 , the transmission mechanism 7 includes a chassis 71. In the middle of the chassis 71, a rotating column 72 is rotatably connected. On the lower part of the outer surface of the rotating column 72, a gear 2 is fixedly connected, and the outer surfaces of the gear 2 and the gear 1 are meshed.

[0028] When the driving motor 1 starts to drive, the piston rod of the driving motor 1 will drive the gear 1 to rotate. At this time, the gear 2 will mesh with the gear 1 and drive the rotating column 72 to start rotating at a constant speed.

[0029] To achieve the purpose of supporting and fixing the bearing mechanism 9, refer to Figure 3 , the support mechanism 8 includes a fixed disk 81. On the upper end of the outer surface of the fixed disk 81, a number of support plates 82 are fixedly connected in an annular array, which can stably support the bearing disk 91.

[0030] For the purpose of carrying the detection component 10, refer to Figure 4 , the carrying mechanism 9 includes a carrying disk 91. In the middle of the inner cavity of the carrying disk 91, a rotating member 92 is rotatably connected. In the middle of the inner surface of the carrying disk 91, an annular groove 93 communicating with the outside is formed. In the inner cavity of the annular groove 93, a plurality of rollers 94 are rotatably connected in an annular array. And the lower end of the outer surface of the carrying disk 91 is fixedly connected with a plurality of support plates 82, and the lower end of the outer surface of the rotating member 92 is fixedly connected with the upper end of the outer surface of the rotating column 72.

[0031] When the rotating column 72 rotates, it will drive the rotating member 92 to rotate in the inner cavity of the carrying disk 91. At this time, the outer surface of the rotating rotating member 92 will move relative to the outer surfaces of the plurality of rollers 94. Through the relative movement with the plurality of rollers 94, the rotation of the rotating member 92 can be made more stable, and the outer surface of the rotating member 92 will not be severely worn due to the friction generated during long-term rotation in the inner cavity of the carrying disk 91.

[0032] For the purpose of detecting a thermal power plant, refer to Figure 4 , the detection component 10 includes a fixed column 101. In the upper part of the inner cavity of the fixed column 101, a rotating arm 102 is rotatably connected. On the left end of the outer surface of the rotating arm 102, a detection head 103 is fixedly connected. And the lower end of the outer surface of the fixed column 101 is fixedly connected with the upper end of the outer surface of the rotating member 92. The output end of the piston rod of the electric motor 11 is fixedly connected with the front end of the outer surface of the rotating arm 102.

[0033] When the electric motor 11 starts to drive, it can drive the rotating arm 102 to rotate in the vertical direction, thereby driving the detection head 103 to adjust the angle in the vertical direction.

[0034] It should be noted that the specific installation methods, circuit connection methods, and control methods of the first driving motor 6, the electric motor 11, and the fan 52 in the present invention are all conventional designs, and the present invention will not elaborate in detail.

[0035] Working principle of the utility model: The device can be controlled by a computer control system to move in a thermal power plant through a number of universal wheels 3. During this period, when it is necessary to rotate and adjust the horizontal angle of the detection head 103, the driving motor 1 is driven. The piston rod of the driving motor 1 will drive the gear 1 61 to rotate. At this time, the gear 2 73 will engage with the gear 1 61 to drive the rotating column 72 to start rotating. At the same time, the rotating column 72 will drive the rotating part 92 to start rotating in the inner cavity of the bearing plate 91, and then drive the detection head 103 to start rotating at a constant speed through the fixed column 101. When it is necessary to adjust the vertical angle of the detection head 103, the driving electric motor 11 can be driven to rotate forward and backward to drive the rotating arm 102 to start rotating in the upper part of the inner cavity of the fixed column 101, so as to realize the inspection angle of the detection head 103 to achieve non dead angle and non blind spot detection.
