Description

Technical Field

[0001] This utility model relates to the field of non-destructive testing, specifically a water-cooled wall intelligent inspection robot. Background Technology

[0002] As one of the three main units in a thermal power plant, the boiler is mainly composed of water-cooled walls, superheaters, reheaters, economizers, headers, steam-water connection pipes, and other equipment. Non-destructive testing of water-cooled wall pipes generally uses manual ultrasonic thickness measurement, manual electromagnetic ultrasonic testing, or radiographic testing. This requires the construction of scaffolding platforms or suspended baskets inside the boiler. Due to the large number of water-cooled wall pipes, it is impossible to inspect all of them manually. Only high-risk areas can be inspected locally. With the development of wall-climbing robot technology, remotely controllable thickness measurement equipment based on wall-climbing robots has been applied to water-cooled wall inspection.

[0003] Existing intelligent inspection robots for water-cooled walls often have some problems during use. First, the robot's inspection probe does not have an automatic cleaning function. If the probe surface is contaminated during the inspection process, the robot needs to be removed from the water-cooled wall for cleaning before it can continue to be used, which is very cumbersome. Second, the lighting range is small and cannot be adjusted, making it inconvenient for inspectors to observe the environment around the robot, which is not conducive to its use. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses an intelligent inspection robot for water-cooled walls. (Refer to...) Figures 1-4 A water-cooled wall intelligent inspection robot includes a robot body 1, a detection probe 2 fixedly connected to the bottom of the robot body 1, and a cleaning mechanism 3 and a lighting mechanism 4 respectively provided on the surface of the robot body 1. The cleaning mechanism 3 includes a fixed box 301, the top of which is fixedly connected to the bottom of the robot body 1. A cleaning brush 302 is provided on the front side of the fixed box 301. A first motor 303 is fixedly connected to the inner wall of the fixed box 301. A screw 304 is fixedly connected to the output end of the first motor 303. A screw sleeve 305 is fitted on the surface of the screw 304. Movable rods 306 are fixedly connected to both sides of the front of the screw sleeve 305. One end of the movable rod 306 passes through the fixed box 301 and is fixedly connected to the cleaning brush 302. By setting up the cleaning mechanism 3, it is only necessary to control the first motor 303 to turn on to drive the cleaning brush 302 for adjustment. When the cleaning brush 302 moves, it can clean the surface of the detection probe 2 without removing the robot body 1 from the water-cooled wall for cleaning. By setting up the lighting mechanism 4, the lighting lamp 403 can be adjusted according to the user's needs, which makes it convenient for the inspection personnel to observe the environment around the robot.

[0018] Reference Figure 1 , Figure 2 and Figure 4The lighting mechanism 4 includes an adjustment shell 401, a rotating rod 402 fixedly connected to the surface of the adjustment shell 401, the bottom of the rotating rod 402 being rotatably connected to the top of the robot body 1, a lighting lamp 403 fixedly connected to the surface of the adjustment shell 401, a frame 404 fitted onto the surface of the adjustment shell 401, the bottom of the frame 404 being fixedly connected to the robot body 1, a second motor 405 fixedly connected to the top of the frame 404, the output end of the second motor 405 penetrating into the inner cavity of the frame 404 and fixedly connected to a turntable 406, and the bottom of the turntable 406... An adjusting rod 407 is fixedly connected to the unit. The bottom of the adjusting rod 407 extends into the inner cavity of the adjusting shell 401. By setting up a lighting lamp 403, it can serve as a lighting function. By setting up a frame 404, it can facilitate the installation of the second motor 405. By controlling the operation of the second motor 405, the turntable 406 and the adjusting rod 407 can be driven to rotate. The adjusting rod 407 will slide in the inner cavity of the adjusting shell 401 when it rotates. Since the adjusting shell 401 is restricted, the adjusting rod 407 will drive the adjusting shell 401 to flip forward or backward when it rotates. Reference Figure 2 , Figure 3 and Figure 4 The bottom of the rotating rod 402 is rotatably connected to the robot body 1 through the first bearing. The surface of the adjusting rod 407 is slidably connected to the inner wall of the adjusting shell 401. The surface of the screw 304 is rotatably connected to the inner wall of the fixing box 301 through the second bearing. The surface of the screw 304 is threadedly connected to the screw sleeve 305. By setting the first bearing, the installation of the rotating rod 402 can be facilitated, and the rotating rod 402 can be supported to facilitate its rotation. By setting the second bearing, one end of the screw 304 can be supported to facilitate its rotation. By setting the thread, the screw 304 will drive the screw sleeve 305 to move when it rotates. Reference Figure 1 and Figure 3 The cleaning brush 302 is used in conjunction with the detection probe 2. The surface of the screw sleeve 305 is slidably connected to the inner wall of the fixing box 301. Mounting blocks 307 are fixedly connected to both sides of the fixing box 301. The surface of the mounting blocks 307 is fixedly connected to the robot body 1 by bolts. By setting the cleaning brush 302, it can be used to clean the surface of the detection probe 2. By setting the mounting blocks 307, it is easy to connect the fixing box 301 and the robot body 1. By setting the bolts, the mounting blocks 307 and the fixing box 301 can be fixed to the bottom of the robot body 1.

[0019] Working principle: The walking module in the robot body 1 is attracted to the water-cooled wall being tested by ferromagnetic attraction. The robot body 1 can walk on the water-cooled wall. The operator controls the robot body 1 to move to the area of ​​the water-cooled wall tube panel to be tested through the controller. The thickness can be checked by activating the detection probe 2. The thickness is used to determine whether there is any damage to the water-cooled wall. When the surface of the detection probe 2 is contaminated, the first motor 303 can be activated to drive the screw 304 to rotate. The rotation of the screw 304, through the cooperation of the screw sleeve 305 and the moving rod 306, can drive the cleaning brush 302 to move. Moving the robot body 1 allows for cleaning of the surface of the detection probe 2, preventing contamination that could affect the detection results. This also saves time compared to removing the robot body 1. When adjusting the lighting angle, the second motor 405 can be activated to rotate the turntable 406 and the adjusting rod 407. The adjusting rod 407 will slide within the inner cavity of the adjusting shell 401. Since the adjusting shell 401 is restricted, the adjusting rod 407 will rotate and cause the adjusting shell 401 to flip forward or backward. The adjusting shell 401 can then adjust the angle of the lighting lamp 403, facilitating personnel to view the environment around the robot body 1.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
