Description

Technical Field

[0001] The present invention relates to the technical field of endoscopes, and particularly to a high-temperature endoscope inspection device. Background Art

[0002] Endoscopes have obvious advantages in the internal inspection of pipelines. By inserting the endoscope into the pipeline and using the image information of the inner wall of the pipeline captured by it to determine the specific situation inside the pipeline, and it can be used for pipeline flaw detection. However, the existing pipeline endoscopes cannot maintain good stability during actual use. When moving along the inside of the pipeline, the lens is prone to torsion or friction with the inner wall of the pipeline. Therefore, it is necessary to invent an endoscope inspection device that can avoid this situation.

[0003] Chinese Patent with Publication No. CN109752770B discloses an endoscope for inspecting the inner cavity of a pipeline, which includes a central threaded rod, an inclined rod, a first support rod, a second support rod, a crawler, a collector, an led lamp, a camera, a support disc, a moving column, a fixed block, a rotating column, a brush, a motor, a connecting claw, a brush support, etc. The rollers on the crawler are in contact with the inner wall surface of the pipeline, which facilitates the entry of the endoscope device into the pipeline and also increases the stability of the endoscope device when moving downward; the rotation of the motor drives the rotating column to rotate around the fixed block through the connecting claw, and the camera and the led lamp installed on the rotating column rotate accordingly. The rotation of the rotating column drives the camera to rotate so that the camera can observe the inner wall of the pipeline in all directions; when the deformation strip reaches the high-temperature phase temperature, it changes from a straight shape to an arc shape, and all the deformation strips enclose an umbrella shape. During the process of lifting the endoscope device, the bristles on the deformation strip clean the inner wall of the pipeline, and the deformation strip returns to a straight shape after cooling.

[0004] However, this device still has deficiencies: when the pipeline is a pipeline with a non-fixed inner diameter, the movement of this device inside the pipeline cannot be adaptively adjusted according to the inner diameter of the pipeline, resulting in the situation that the whole device still twists when passing through a relatively spacious area inside the pipeline. And in the working state of the cleaning structure of this device, if there are a large number of impurities accumulated in its return direction, it is easy to cause the device to jam, or the impurities penetrate through the gaps of the deformation strip, thus unable to thoroughly clean the inside of the pipeline.

The expansion and contraction drive assembly includes a connecting rod A2, a carriage 6, a spring A8, and a movable handle 9. A fixed handle 106 is arranged on the housing 1. The connecting rod A2 includes the same number of groups as the support plates 3, and the number of each group of connecting rods A2 is not less than two. A limiting groove 101 is arranged on the housing 1. One end of the connecting rod A2 is rotatably connected to the inner wall of the limiting groove 101. The end of each connecting rod A2 away from the housing 1 is rotatably connected to the corresponding support plate 3. The carriage 6 is sleeved on the exhaust pipe 5 and is slidably connected to its outer wall and the inner wall of the limiting groove 101. A plurality of connecting rods B7 are arranged on the carriage 6 in a circular array around the axis of the housing 1. The end of each connecting rod B7 away from the housing 1 is respectively rotatably connected to the corresponding support plate 3. The connecting rod B7 is opposite to the connecting rod A2. The spring A8 is sleeved on the exhaust pipe 5. The two ends of the spring A8 are respectively abutted against the lower wall of the limiting groove 101 and the lower surface of the carriage 6. One end of the movable handle 9 is inserted into the limiting groove 101 and is connected to the carriage 6. The movable handle 9 is slidably connected to the fixed handle 106. The expansion and contraction drive assembly is arranged on the housing 1 and drives each group of support plates 3 to move away from or close to each other synchronously.

The rotation drive assembly includes a motor 16. A rotating shaft 121 is coaxially arranged on the turbine 12. The rotating shaft 121 is rotatably connected to the housing 1. The body of the motor 16 is arranged in the protective cover 14. The output end of the motor 16 is connected to the rotating shaft 121. The rotation drive assembly drives the turbine 12 to rotate at a high speed. The internal gear ring 17 is arranged on the housing 1 and rotates coaxially with it.

The transmission assembly is drivingly connected to turbine 12 and internal gear ring 17.

[0028] In this embodiment, first, hold fixed handle 106 and movable handle 9, and squeeze movable handle 9 towards fixed handle 106. Movable handle 9 pushes carriage 6 to slide, and the sliding carriage 6 drives link B7 to move, thereby causing link B7 to pull support plate 3 and retract it until it fits against the surface of housing 1. First insert wide-angle probe 15 of this device into the pipeline, and then completely place housing 1 into the pipeline. Then release movable handle 9. Spring A8 releases its potential energy and pushes carriage 6 to slide back, thereby causing link B7 to cooperate with link A2 to expand support plate 3 until all support wheels 4 are in tight contact with the inner wall of the pipeline. At this time, wide-angle probe 15 is in the central position inside the pipeline, and information inside the pipeline can be obtained through wide-angle probe 15; before pushing this device to move inside the pipeline, first power on the device, and connect exhaust pipe 5 to an external pipeline made of a relatively thin material with high temperature resistance characteristics. By pushing the external pipeline, the device can be pushed to move inside the pipeline. During the movement process, no matter how the inner diameter of the pipeline changes, wide-angle probe 15 is always coaxial with the pipeline. If impurities deposited inside the pipeline need to be cleaned, at this time, start motor 16. Motor 16 drives turbine 12 to rotate at a high speed. During the rotation of turbine 12, the air at its air inlet end enters conical cavity 102 along intake pipe 13 and intake hole A103 from behind the advancing direction of support plate 3. Turbine 12 pushes and compresses the air flow and discharges it along exhaust pipe 5 and the external pipeline. During the exhaust process of exhaust pipe 5, a relatively large negative pressure value appears on the nozzle side of dust collection pipe 10, so that air enters exhaust pipe 5 obliquely along dust collection cover 11 and dust collection pipe 10 and is discharged together. During this process, motor 16 drives internal gear ring 7, elastic telescopic rod, and brush plate 21 to rotate at a high speed through gear A23 and gear B24, thereby causing the impurities to be scraped off. The scraped-off impurities enter dust collection cover 11 under the drive of the flowing air at the opening side of dust collection cover 11 and are discharged through dust collection pipe 10 and exhaust pipe 5.

[0029] Embodiment Two

[0030] As Figure 1 、 Figure 2 and Figure 4As shown in the figure, a high-temperature endoscope inspection device proposed by the present invention discloses a specific structure of an elastic telescopic rod in this embodiment compared with Embodiment 1. The elastic telescopic rod includes a fixed frame 18, a sliding rod 20, and a spring B22. One end of the fixed frame 18 is connected to the internal gear ring 17. A slider 19 is arranged inside the fixed frame 18 and is slidably connected thereto. One end of the sliding rod 20 is inserted into the fixed frame 18 and connected to the slider 19. The end of the sliding rod 20 away from the slider 19 is connected to the brush plate 21. The spring B22 is sleeved on the sliding rod 20, and both ends of the spring B22 are respectively abutted against the inner wall of the fixed frame 18 and the slider 19.

[0031] In this embodiment, when the motor 16 drives the rotation of the rotating shaft 121 to drive the rotation of the internal gear ring 17, the centrifugal force generated by the high-speed rotating internal gear ring 17 causes the brush plate 21 to drive the sliding rod 20 and the slider 19 to slide until the brush plate 21 abuts against the inner wall of the pipeline. At this time, the spring B22 is compressed and stores potential energy. When the internal gear ring stops rotating, the spring B22 releases the potential energy and pushes the slider 19 backward, so that the brush plate 21 automatically retracts and resets, without hindering the taking and placing of the device in the pipeline.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art.
