Description

Technical Field

[0001] This utility model relates to the technical field of wheeled imaging inspection equipment, specifically a wheeled imaging inspection equipment for air ducts and pipelines. Background Technology

[0002] Air ducts are a collective term for a series of pipes specifically designed to transport air and air mixtures. They can be made of various materials, including thin steel plates, aluminum plates, rigid PVC sheets, fiberglass, and other composite materials. Air ducts are primarily used in building air conditioning systems, responsible for functions such as supply air, return air, fresh air intake, and exhaust air. The application of these ducts requires inspection. During duct inspection, duct inspection devices can perform endoscopic inspections. After the inspection device enters the duct, it captures images using its onboard camera and transmits the data to a control computer. This assists the operator in assessing the duct's condition for cracks, corrosion, and weld quality, allowing for timely corrective action.

[0003] As disclosed in the patent announcement CN215897906U, a multifunctional imaging device for pipeline inspection includes a housing. A partition is fixedly connected to the inner wall at the center of the bottom of the housing. A motor is fixedly connected to the center of the right side of the partition. The right drive end of the motor is fixedly connected to the left end of the rotating shaft. A support plate is fixedly connected to the right end of the rotating shaft. A blower is fixedly connected to the top left side of the support plate. An air inlet pipe is fixedly connected to the front air inlet end of the blower. An exhaust pipe is fixedly connected to the rear air outlet end of the blower.

[0004] Although it achieves the goal of cleaning the inner wall of the pipeline with a blower, preventing dust and debris from affecting the camera's shooting effect, improving the accuracy of pipeline inspection, avoiding safety hazards caused by pipeline quality problems, and improving the safety of pipeline use, it also improves the comprehensiveness of pipeline inspection by adjusting the camera angle with a motor, avoiding safety hazards caused by missed inspections. It is worth promoting.

[0005] However, this does not solve the problem that existing wheeled imaging inspection equipment is generally not convenient to adjust and move to adapt to ducts of different diameters, is not convenient to rotate and capture images from multiple angles, and is not convenient to clean dirt from the inner wall of the duct, which greatly affects the range of image capture and the accuracy of duct inspection.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A duct wheel-type imaging inspection device includes a storage tank and a first support frame. The first support frame is installed at the center of the storage tank and extends to the surface of the storage tank. A flip-top cover is installed on the outer wall of the storage tank. Three sets of limiting rods are installed inside the first support frame and extend to the outside of the first support frame. Three sets of large arms are symmetrically arranged at equal intervals on the outer wall of the first support frame. A camera is installed on the outside of the first support frame.

[0010] Optionally, three sets of forearms are movably mounted on the outer wall of the threaded sleeve at equal intervals, and the forearms are movably connected to the upper arm.

[0011] Optionally, each of the upper arms is equipped with a hinge shaft at its bottom end, and the upper arm is connected to the first support frame via the hinge shaft. Each of the upper arms is equipped with a traveling frame on its top outer wall.

[0012] Optionally, all of the outer walls of the walking frame are movably mounted with walking wheels, and a third motor is mounted on the outer wall of a set of booms on the side close to the walking frame, and a first right-angle gear is mounted on the output end of the third motor.

[0013] Optionally, a first rotating shaft is installed inside the walking frame on one side of the first right-angle gear, and the first rotating shaft extends to the outside of the walking frame and is connected to the walking wheel. A second right-angle gear is installed at the end of the first rotating shaft near the first right-angle gear, and the first right-angle gear meshes with the second right-angle gear.

[0014] Optionally, sealing plates are installed on both sides of the threaded sleeve, and the limiting rod is connected to the sealing plates. A curved arm is installed on the outer wall of the sealing plate, and a second motor is installed on the outer wall of the curved arm.

[0015] Optionally, a connecting block is installed at the output end of the second motor, a first gear is installed on the outer wall of the connecting block, a fourth rotating shaft is installed inside the first gear and is connected to the camera, a first motor is installed on the lower part of the outer wall of the connecting block near the first gear, a second gear is installed at the output end of the first motor and the second gear meshes with the first gear.

[0016] Optionally, an electric push rod is installed at the bottom of the camera, a connecting plate is installed on the outer wall of the electric push rod, and clamping arms are symmetrically and movably installed on the outer wall of the connecting plate.

[0017] Optionally, a push block is installed at the output end of the electric push rod, and a linkage arm is symmetrically and movably installed at the end of the push block away from the electric push rod. The linkage arm is movably connected to the clamping arm. A rotating pin is provided at the end of the clamping arm near the connecting plate, and the clamping arm is movably connected to the connecting plate through the rotating pin.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the wheeled image inspection device not only realizes the convenient adjustment of the wheeled image inspection device to adapt to the movement of air ducts of different diameters, but also facilitates multi-angle rotation to collect images, increases the range of image acquisition, and facilitates the cleaning of dirt on the inner wall of the air duct, thus improving the accuracy of air duct inspection.

[0019] A servo motor drives a threaded rod to rotate, a threaded sleeve drives a forearm to move, and the forearm drives the main arm to rotate around a hinge axis. This allows the three main arms to drive the traveling frame and wheels to open at a certain angle, with the wheels contacting the inner wall of the duct. A third motor drives the first right-angle gear to rotate, and the second right-angle gear drives the first rotating shaft to rotate. With the support of the traveling frame, the first rotating shaft drives the wheels to rotate.

[0020] A camera is used to collect data on the inner wall of the duct. The camera transmits the data to an external internet computer via a wireless transmission device inside the storage tank, allowing the external computer to perform data analysis and inspection on the images. A second motor drives a connecting block to rotate, which in turn drives the camera, electric push rod, clamping arm, and linkage arm to rotate in the appropriate direction. After rotating to the appropriate position, the first motor is activated. The first motor drives the second gear to rotate, which in turn drives the fourth rotating shaft to rotate. Supported by the fourth rotating shaft, the camera, electric push rod, clamping arm, and linkage arm rotate, facilitating multi-position rotational image acquisition. This enables the wheeled image inspection equipment to acquire images from multiple angles, increasing the range of image acquisition.

[0021] The electric push rod drives the push block to move, and the push block drives the clamping arm to rotate around the pivot pin via the linkage arm. The connecting plate provides movable support for the clamping arm via the pivot pin, so as to facilitate the clamping arm to pick up dirt. This enables the wheeled image inspection equipment to easily pick up dirt, which facilitates the cleaning of dirt on the inner wall of the air duct and improves the accuracy of air duct inspection.

[0037] like Figures 1 to 6As shown, an embodiment of this utility model provides a duct wheel-type imaging inspection device, including a storage tank 1 and a first support frame 2. The first support frame 2 is installed at the center of the storage tank 1 and extends to the surface of the storage tank 1. A flip cover 3 is installed on the outer wall of the storage tank 1. Three sets of limiting rods 12 are installed inside the first support frame 2 and extend to the outside of the first support frame 2. Three sets of large arms 18 are symmetrically arranged at equal intervals on the outer wall of the first support frame 2. A camera 4 is arranged on the outside of the first support frame 2. Servo motors 28 are symmetrically installed at the center of the inside of the first support frame 2. Each output end of the machine 28 is equipped with a threaded rod 31, and each threaded rod 31 is fitted with a threaded sleeve 13. Three sets of small arms 27 are movably installed on the outer wall of each threaded sleeve 13 at equal intervals. The small arms 27 are movably connected to the large arms 18. Each bottom end of the large arms 18 is equipped with a hinge shaft 25, and the large arms 18 are connected to the first support frame 2 through the hinge shaft 25. Each top outer wall of the large arms 18 is equipped with a traveling frame 10, and each traveling frame 10 is movably equipped with a traveling wheel 11. A third motor 14 is installed on the side of one set of large arms 18 near the traveling frame 10. The output end of the third motor 14 is equipped with a first right angle gear 15.

[0038] The device is placed inside the ductwork. The servo motor 28 is turned on, which drives the threaded rod 31 to rotate. Under the threaded connection between the threaded rod 31 and the threaded sleeve 13, the threaded sleeve 13 is moved. The threaded sleeve 13 drives the forearm 27 to move. The forearm 27 drives the main arm 18 to rotate around the hinge shaft 25, so that the three sets of main arms 18 can drive the walking frame 10 and the walking wheels 11 to open to a certain angle. The walking wheels 11 contact the inner wall of the ductwork. The third motor 14 is turned on, which drives the first right-angle gear 15 to rotate. The first right-angle gear 15 drives the second right-angle gear 16 to rotate. The second right-angle gear 16 drives the first rotating shaft 17 to rotate. With the support of the walking frame 10, the first rotating shaft 17 drives the walking wheels 11 to rotate. The multiple sets of walking wheels 11 work together to facilitate the movement of the device on the inner wall of the ductwork. This enables the wheeled image inspection device to be easily adjusted to adapt to the movement of ductwork of different diameters, improving the convenience of moving ductwork of different diameters.

[0039] A first rotating shaft 17 is installed inside the walking frame 10 on one side of the first right angle gear 15, and the first rotating shaft 17 extends to the outside of the walking frame 10 and is connected to the walking wheel 11. A second right angle gear 16 is installed at the end of the first rotating shaft 17 near the first right angle gear 15, and the first right angle gear 15 and the second right angle gear 16 mesh. Sealing plates 26 are installed on both sides of the threaded sleeve 13, and the limiting rod 12 is connected to the sealing plate 26. A curved arm 19 is installed on the outer wall of the sealing plate 26, and a second motor 9 is installed on the outer wall of the curved arm 19. A connecting block 8 is installed at the output end of the second motor 9. A first gear 5 is installed on the outer wall of the connecting block 8. A fourth rotating shaft 30 is installed inside the first gear 5 and is connected to the camera 4. A first motor 7 is installed on the outer wall of the connecting block 8 near the bottom of the first gear 5. A second gear 6 is installed at the output end of the first motor 7, and the second gear 6 meshes with the first gear 5.

[0040] Camera 4 is activated to collect data on the inner wall of the duct. Camera 4 transmits the data to an external internet computer via a wireless transmission device inside storage tank 1, facilitating data analysis and detection. When the acquisition range of camera 4 is limited, the second motor 9 is activated. Supported by the curved arm 19, the second motor 9 drives the connecting block 8 to rotate. The connecting block 8 then rotates camera 4, electric push rod 20, clamping arm 22, and linkage arm 24. After rotating to the appropriate position, the first motor 7 is activated. The first motor 7 drives the second gear 6 to rotate, which in turn drives the first gear 5. The first gear 5 then drives the fourth rotating shaft 30 to rotate. Supported by the fourth rotating shaft 30, the camera 4, electric push rod 20, clamping arm 22, and linkage arm 24 rotate, facilitating multi-position rotational image acquisition. This enables multi-angle rotational image acquisition by the wheeled image detection device, increasing the image acquisition range.

[0041] An electric push rod 20 is installed at the bottom of the camera 4. A connecting plate 21 is installed on the outer wall of the electric push rod 20. Clamping arms 22 are symmetrically and movably installed on the outer wall of the connecting plate 21. A push block 23 is installed at the output end of the electric push rod 20. A linkage arm 24 is symmetrically and movably installed at the end of the push block 23 away from the electric push rod 20. The linkage arm 24 is movably connected to the clamping arm 22. A rotating pin 29 is provided at the end of the clamping arm 22 near the connecting plate 21. The clamping arm 22 is movably connected to the connecting plate 21 through the rotating pin 29.

[0042] When there is dirt on the inner wall of the duct, the electric push rod 20 is opened, and the electric push rod 20 drives the push block 23 to move. The push block 23 drives the clamping arm 22 to rotate around the rotating pin 29 via the linkage arm 24. The connecting plate 21 provides movable support for the clamping arm 22 via the rotating pin 29, so as to facilitate the clamping arm 22 to pick up the dirt. This realizes the convenient picking up of dirt by the wheeled image inspection equipment, which facilitates the cleaning of dirt on the inner wall of the duct and improves the accuracy of duct inspection.

[0043] The working principle of the technical solution provided by this utility model is as follows: First, by placing the equipment inside the air duct, the servo motor 28 drives the threaded rod 31 to rotate. Under the threaded connection between the threaded rod 31 and the threaded sleeve 13, the threaded sleeve 13 is driven to move. The threaded sleeve 13 drives the forearm 27 to move. The forearm 27 drives the upper arm 18 to rotate around the hinge shaft 25, so that the three sets of upper arms 18 can drive the walking frame 10 and the walking wheels 11 to open to a certain angle. The walking wheels 11 contact the inner wall of the air duct. The third motor 14 drives the first right-angle gear 15 to rotate. The second right-angle gear 16 drives the first rotating shaft 17 to rotate. Under the support of the walking frame 10, the first rotating shaft 17 drives the walking wheels 11 to rotate. The multiple sets of walking wheels 11 cooperate to facilitate the equipment to move on the inner wall of the air duct. The camera 4 collects data of the image of the inner wall of the air duct. The camera 4 collects data through the storage tank 1. The wireless transmission equipment transmits data to an external internet computer, facilitating image data analysis and detection. The second motor 9 drives the connecting block 8 to rotate, which in turn drives the camera 4, electric push rod 20, clamping arm 22, and linkage arm 24 to rotate. After rotating to the appropriate position, the first motor 7 drives the second gear 6 to rotate, and the first gear 5 drives the fourth rotating shaft 30 to rotate. Supported by the fourth rotating shaft 30, the camera 4, electric push rod 20, clamping arm 22, and linkage arm 24 rotate, facilitating multi-position rotation for image acquisition. The electric push rod 20 drives the push block 23 to move, and the push block 23 drives the clamping arm 22 to rotate around the rotating pin 29 via the linkage arm 24. The connecting plate 21 provides movable support for the clamping arm 22 via the rotating pin 29, facilitating the clamping arm 22 to pick up dirt, thus completing the operation of the wheeled image inspection equipment.
