[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 creative efforts are within the scope of protection of the present invention.
[0023] See also Figure 1-4 , the utility model provides a technical solution:
[0024] See Figure 1 Figure 3 As shown, a portable boiler safety inspection mechanism includes a mounting base 1, a camera 9 is installed at the bottom of the mounting base 1, a moving mechanism and a limiting mechanism for locking the folding angle of the moving mechanism are provided above the mounting base 1, the moving mechanism includes a moving frame 5, the outer arc wall of the mounting base 1 and the moving frame 5 are respectively provided with a folding strip 2 and a folding strip 3 from bottom to top, the number of the folding strip 2 and the folding strip 3 is four and is symmetrically distributed at equal intervals, the bottom of the folding strip 2 and the top of the folding strip 3 are respectively rotated with the outer arc wall of the mounting base 1 and the moving frame 5 Dynamic connection, a hinge seat 4 is installed at the connection, a roller seat 15 and a hinge seat 2 16 are connected between the folding strip 1 2 and the folding strip 2 3, the bottom of the folding strip 2 3 and the top of the roller seat 15, as well as the top of the folding strip 1 2 and the bottom of the roller seat 15 are rotatably connected through the hinge seat 2 16, a roller 18 is installed in the roller seat 15, and the roller 18 is equipped with a rotating shaft 19 that passes through the outer wall of the roller seat 15, and a motor box 21 is fixedly installed on the outer wall of the roller seat 15, and a motor 20 is provided in the motor box 21, and the motor 20 is transmission-connected to the rotating shaft 19. During the specific implementation process, when the movable frame 5 moves up and down, it will drive the folding strip 1 2 and the folding strip 2 3 to fold. When moving downward, the angle between the folding strip 1 2 and the folding strip 2 3 will gradually move away from the center position of the movable frame 5 until the roller 18 is in contact with the inner wall of the boiler pipe. The motor 20 is started to drive the roller 18 to rotate, thereby driving the entire mechanism to move inside the boiler pipe. During the movement of the mechanism, the camera 9 will capture the image inside the boiler pipe and transmit it to the inspector. The inspector can judge whether there are safety hazards in the boiler pipe by observing the image.
[0025] See Figure 1 and Figure 4 As shown, the limiting mechanism includes a hydraulic rod 6 mounted at the center of the upper surface of the mounting base 1. The movable end of the hydraulic rod 6 is connected to a connecting block 14, which is fixedly connected to the inner arc wall of the movable frame 5. During implementation, as the hydraulic rod 6 contracts, the connecting block 14 drives the movable frame 5 downward, and the folding bars 1 and 2 gradually fold until the rollers 18 contact the inner wall of the boiler pipe. To prevent deviation when folding to the desired position, the movable end of the hydraulic rod 6 can be controlled to stop moving to maintain the current position.
[0026] See Figure 3 As shown, one end of the rotating shaft 19 located within the roller seat 15 is rotatably connected to the roller seat 15 via a bearing. A limit block 17 is installed on the side of the hinge seat 2 16 away from the hydraulic rod 6. The bottom of the limit block 17 is fixedly connected to the top of the roller seat 15. In the specific implementation process, the rotating shaft 19 is responsible for transmitting the driving force of the motor 20 to the roller 18, enabling it to rotate. The roller seat 15 serves as the mounting base for the roller 18 and is internally provided with a bearing seat for mounting and supporting the rotating shaft 19. The limit block 17 is installed on the side of the hinge seat 2 16 away from the hydraulic rod 6 to prevent the folding angles of the folding strips 1 2 and 3 from being misaligned, causing the roller 18 to deviate from the inner wall of the boiler pipe.
[0027] See Figure 2 As shown, four connecting bars 10 are evenly spaced along the center of the roller base 15 on the upper surface of the roller base 15. A hand grip 11 is connected to the top of each of the four connecting bars 10. A lifting ring 12 is mounted above the hand grip 11, which is connected to a lifting rope 13. The hand grip 11 is also equipped with an anti-slip pad. In practice, the connecting bars 10 not only provide stable support for the hand grip 11 but also ensure that the hand grip 11 remains in a stable position during movement or operation. The lifting ring 12 serves as a connection point, allowing operators to use the lifting rope 13 to lift or move the mechanism, particularly when inserting or removing the mechanism from a boiler pipe.
[0028] See Figure 1 As shown, an LED light bar 8 is fixedly mounted below the mounting base 1 and is sleeved onto the outer wall of the camera 9. A battery 7 is installed within the mounting base 1 and is electrically connected to the hydraulic rod 6, the LED light bar 8, the camera 9, and the motor 20. In practice, the LED light bar 8 provides illumination, ensuring that the camera 9 can clearly capture images of the interior of the boiler pipes even when the interior is poorly lit. The battery 7 provides power to all components, allowing them to operate independently without an external power source, making them ideal for use in environments such as boilers where external power is difficult to access.
[0029] Working principle:
[0030] Step 1: When the mechanism is in the initial state, the mobile frame 5 is connected to the mounting base 1 through the folding bar 1 2 and the folding bar 2 3, and is maintained at a certain height for the operator to hold or lift. The battery 7 provides power for the hydraulic rod 6, LED light bar 8, camera 9 and motor 20 and other components. The operator uses the lifting rope 13 and the lifting ring 12 to lift the mechanism into the boiler pipe, or holds the hand grip 11 to operate, starts the hydraulic rod 6, and its movable end pushes the connecting block 14 and the mobile frame 5 to move downward. As the mobile frame 5 descends, the folding bar 1 2 and the folding bar 2 3 gradually fold, and the roller 18 gradually approaches and fits the inner wall of the boiler pipe. When the roller 18 is completely in contact with the inner wall of the boiler pipe, the motor 20 is started, and the motor 20 drives the roller 18 to rotate through the rotating shaft 19, thereby driving the entire mechanism to move inside the boiler pipe.
[0031] Step 2: During the movement of the mechanism, the camera 9 continuously captures images of the inside of the boiler pipe and transmits them to the inspector. The LED light bar 8 provides lighting to ensure that the camera 9 can clearly capture images in low light conditions. The limit block 17 is installed on the side of the hinge seat 2 16 away from the hydraulic rod 6 to prevent the folding strip 1 2 and the folding strip 2 3 from offsetting during the folding process, ensuring that the roller 18 always fits the inner wall of the boiler pipe. When the mechanism moves to the required position, the movable end of the hydraulic rod 6 is controlled to stop moving to achieve angle locking, keeping the mechanism stable and motionless in the current position.
