Technical Field

[0001] This invention belongs to the field of pipeline inspection technology, and in particular to an amphibious pipeline inspection robot. Background Technology

[0002] For some tasks performed in special environments, such as internal inspections of pipes with narrow diameters or small pipes, or safety inspections in flammable and explosive environments, intelligent detection equipment such as pipeline inspection robots are usually used. These devices can not only clearly observe the internal conditions of the pipeline, but are also safer because they do not require the personal involvement of personnel.

[0003] Existing pipeline inspection robots still have shortcomings. For example, the spiral roller assembly and pipeline culvert inspection robot published by CN112590969A on December 22, 2020, discloses: "This invention discloses a spiral roller assembly and a pipeline culvert inspection robot, wherein the spiral roller is used in the pipeline culvert inspection robot, the pipeline culvert inspection robot includes a robot body, the spiral roller assembly includes a first support frame, a spiral roller, and a second drive assembly, the first support frame is used to support the robot body, two spiral rollers are provided, the two spiral rollers are respectively connected to the two ends of the first support frame to drive the robot body to move, and the first drive assembly is connected to the first support frame to drive the two spiral rollers to move closer or further apart. The technical solution of this invention can solve the problem that the pipeline culvert inspection robot may not be able to pass smoothly in environments with uncertain spatial dimensions, thus affecting its normal operation."

[0004] As can be seen from the closest published patent mentioned above, although the patent solves the problem of adjusting the overall size of the robot by reducing the distance between the two spiral rollers, it still has the following shortcomings: the structure is not stable enough, there is not enough driving power, no camera that can be adjusted at multiple angles is installed, and it does not have a certain buoyancy and good lighting effect. Summary of the Invention

[0005] The purpose of this invention is to provide an amphibious pipeline inspection robot.

[0006] The objective of this invention is achieved as follows: An amphibious pipeline inspection robot includes a drive wheel connected to a drive motor; and a support plate located above the drive motor. The drive wheel has helical blades surrounding its side. The support plate is connected to a first motor, which is connected to a camera via a connector. The camera can rotate relative to the connector.

[0007] As a further improvement, the first motor drives the camera to rotate radially, and the second motor inside the connector drives the camera to rotate axially, thereby enabling the camera to adjust its position in multiple directions.

[0009] As a further improvement, the drive wheel is provided in two parts and connected to it by a support rod to form a stable triangular structure.

[0010] As a further improvement, hollow floating valves are provided on the left and right sides of the drive wheel.

[0011] As a further improvement, the drive motor is provided with four sets and symmetrically arranged on the support plate. The drive motor is fixedly connected to the first helical gear.

[0013] As a further improvement, a set of LED lights is fixed on each of the left and right sides of the first motor, and the illumination angle of each set of LED lights is different.

[0014] As a further improvement, the support plate is provided with a power socket, and the camera is provided with a ring-shaped LED light strip.

[0015] The following are the outstanding and beneficial technical effects of this invention compared to the prior art.

[0016] (1) The first motor drives the camera to rotate radially, and the second motor inside the connector drives the camera to rotate axially, so that the camera can adjust its position in multiple directions, which is beneficial for users to observe the inside of the pipe from multiple angles through the camera.

[0020] (5) A set of LED lights are fixed on the left and right sides of the first motor respectively. Each set of LED lights has a different illumination angle, thereby realizing the long-distance illumination and close-range illumination of the camera. The camera is equipped with a ring-shaped LED light strip for auxiliary lighting. Attached Figure Description

[0026] The present invention will be further described below with reference to specific embodiments: like Figure 1 and Figure 5 As shown, the amphibious pipeline inspection robot includes two drive wheels 2 connected to four drive motors 1; and a support plate 3 located above the drive motors 1. The drive wheels 2 have spiral blades 4 surrounding their sides. The support plate 3 is connected to a first motor 5, which is connected to a camera 7 via a connector 6. The camera 7 can rotate relative to the connector 6. The first motor 5 drives the camera 7 to rotate radially, and a second motor inside the connector 6 drives the camera 7 to rotate axially, thereby allowing the camera 7 to adjust its position in multiple directions.

[0027] In actual operation, the second motor is connected to the drive pulley 9 inside the connector 6. When the second motor rotates, it drives the drive pulley 9 to rotate. Since the drive pulley 9 is connected to the driven pulley 10 via a belt, the drive pulley 9 drives the driven pulley 10 to rotate. When the driven pulley 10 rotates, it drives the camera 7 to rotate radially along the shaft of the first motor 5 via the connecting rod 11. In addition, when the first motor 5 rotates, it can also drive the camera on the connector 6 connected to it to rotate axially around its shaft. Therefore, the above structure can realize multi-angle adjustment of the camera, which is beneficial for users to observe the inside of the pipe from multiple angles through the camera.

[0028] like Figure 4 As shown, the drive motor 1 has four sets symmetrically arranged on the support plate 3. The drive motor 1 is fixedly connected to the first helical gear 14. When the drive motor 1 drives the first helical gear 14 to rotate, since the first helical gear 14 and the second helical gear 15 are engaged, the first helical gear 14 drives the second helical gear 15 to rotate. Thus, the second helical gear 15 drives the transmission shaft 17, which is fixed below with the third helical gear 16, to rotate. When the transmission shaft 17 and the third helical gear 16 rotate, they drive the fourth helical gear 18, which is engaged with them, to rotate. The fourth helical gear 18 then drives the drive wheel 2 to rotate through the rotating shafts 19 provided at the left and right ends of the drive wheel 2, thereby enabling the drive wheel 2 to drive the entire robot to move forward or backward.

[0029] The rotating shaft 19 rotates around the bearing 20, which is fixed inside the first sleeve 21. One side of the first sleeve 21 is connected to the float valve 13, which provides buoyancy, thus helping the robot to be used in water. The drive shaft 17 is fixed inside the second sleeve 22 via the bearing 20. The drive shaft 17 and the rotating shaft 19 are perpendicular to each other. The first helical gear 14 and the second helical gear 15 are located inside the housing 23. The housing 23 is fixedly connected to the drive motor 1 by several screws 24. The end of the housing 23 is connected to the housing cap 25 by threads.

[0030] like Figures 1 to 3 As shown, there are two drive wheels 2 connected to each other by a support rod 12, forming a stable triangular structure. Therefore, the overall structure has strong stability. Even when encountering obstacles or being impacted, the entire structure can remain stable and is not easy to fall apart, making the robot very durable and reducing its maintenance costs. In addition, the robot has a total of two drive wheels 2, and each drive wheel 2 has two drive motors 2 at both ends. The four drive motors 2 not only provide sufficient power, but also allow the robot to change its forward and backward direction at any time without having to turn around.

[0031] like Figure 1As shown, a set of LED lights 26 are fixed on the left and right sides of the first motor 5, and the illumination angle of each set of LED lights 26 is different, thereby realizing the long-distance illumination and close-range illumination of the camera 7. The camera 7 is provided with a ring-shaped LED light strip 28, which is used for auxiliary lighting. The support plate 3 is provided with a power socket 27, which can be used to charge the internal battery or to plug the robot into the power cord.

[0032] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
