Description

Technical Field

[0001] The invention relates to the technical field of foreign body prevention management in nuclear power plants, and in particular to a device for fine-tuning the position of an endoscope and a long-distance salvaging tool. Background Art

[0002] During the construction of nuclear power plants, strict foreign body control and inspection are required for process systems, and endoscopic inspection is an important means of cleanliness inspection and foreign body search. When using a pipeline flexible endoscope, the insertion depth of the endoscope is generally controlled by hand, and the angle or direction of the endoscope is rotated by hand. In actual operation, pure manual operation is not precise enough and requires repeated adjustments, which makes it difficult to quickly and accurately reach the desired position, resulting in low operating efficiency. It is also difficult to manually maintain the position for a long time, and the stability is poor. Once the hand shakes, it needs to be readjusted. Similar problems also exist in the position of long-distance salvage tools.

[0003] Therefore, it is necessary to invent a fast and portable device for fine-tuning the position of endoscopes and long-distance salvage tools, which is used for fine-tuning and locking the position and angle of pipeline flexible endoscopes and long-distance salvage tools. With the help of this device, the position of foreign objects can be quickly found, and the shooting angle and distance can be adjusted through fine-tuning of the position, and the foreign objects can be removed.

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] A device for fine-tuning the position of an endoscope and a long-distance fishing tool, comprising a clamping telescopic component and a rotating component;

[0028] The clamping telescopic assembly comprises a frame 1, two clamping wheels 2 rotatably connected to the frame 1, and telescopic holes arranged on two side surfaces of the frame 1 perpendicular to the wheel axles of the clamping wheels.

[0029] Among them, the wheel axle 21 of the clamping wheel 2 is fixedly connected to the clamping wheel body, and at least one end of the wheel axle 21 of the clamping wheel 2 is provided with a knob 22. The structure allows the clamping wheel to be rotated by the knob at the end, thereby improving the convenience of operation. Specifically, there are two axles 21, which are respectively connected to the clamping wheel at both ends of the clamping wheel through a keyway or interference fit to achieve relative fixed connection, and the wheel axle 21 and the knob 22 are also connected through a keyway or interference fit. Preferably, knobs 22 are provided at both ends of each clamping wheel 2 to improve the convenience of operation. An arc groove 23 is provided in the middle of the clamping wheel 2, and the maximum depth of the arc groove 23 is less than the radius of the flexible insertion tube 3 of the endoscope or long-distance salvage tool. The structure ensures the effectiveness of the two clamping wheels in clamping the flexible insertion tube. And the surface of the arc groove 23 is provided with a rubber layer or the clamping wheel is made of rubber material. The rubber layer provides a certain elasticity on the one hand, and improves the friction between the clamping wheel and the flexible insertion tube on the other hand, so as to ensure the stability of clamping and the effectiveness of the flexible insertion tube extending and extending by rotating the clamping wheel.

[0030] In addition, a group of circular holes 11 and a group of slot-shaped holes 12 are provided on two opposite sides of the frame 1, the wheel axle of one clamping wheel is rotatably connected to the group of circular holes 11, the wheel axle of the other clamping wheel is rotatably connected to the group of slot-shaped holes 12, an elastic band is provided between the axles of the two clamping wheels 2, and an elastic band is provided between the axles at both ends of the clamping wheel. The slot-shaped holes provide a certain moving space for the clamping wheel, that is, the distance between the two clamping wheels has a certain elasticity, and under the effect of the elastic band, on the one hand, the clamping force between the two clamping wheels can be guaranteed, and on the other hand, the normal extension and extension of the flexible insertion tube will not be affected. And this structure also improves the applicability of the device to flexible insertion tubes of different diameters. An annular groove is provided on the axle 21 of the clamping wheel 2, and the elastic band connects the annular grooves of the two clamping wheels. The structure ensures the stability of the position of the elastic band, that is, the stability of the tightening force provided by the elastic band, thereby ensuring the stability of the clamping force between the two clamping wheels.

[0031] The rotating assembly includes cylinders 4 arranged at the telescopic holes on both sides of the frame 1, a support frame rotatably connected to the two cylinders 4, and a fastening assembly arranged on the support frame for adjusting and fastening the cylinders.

[0032] Specifically, the support frame includes two U-shaped saddles 5 arranged opposite to each other, a saddle upper side strip 6 detachably connected to the upper end of the saddle 5, and a saddle connecting rod 7 connecting the lower ends of the two saddles 5; the fastening assembly includes a tightening block 8 slidably connected to the two inner side walls of the saddle 5, a threaded hole provided on the saddle upper side strip 6, and a tightening screw 9 passing through the threaded hole and contacting the tightening block 8. The structure is simple, and is rotatably connected to the cylinder through the U-shaped saddle and the tightening block, and the tightening force of the tightening block on the cylinder can be adjusted by rotating the tightening screw. When loosening, the cylinder can rotate freely, and when tightening, the stability of the angle of the flexible insertion tube can be effectively guaranteed. The tightening block 8 is slidably connected to the saddle 5 through a concave and convex keyway. The structure ensures the stability of the sliding direction of the tightening block.

[0033] In addition, the inner side surface of the saddle 5 is smooth, and the tightening block 8 is provided with an arc surface, and the arc surface is provided with a rubber layer. When the tightening block is loosened, the smooth inner side surface of the saddle can ensure the smoothness of the rotation of the cylinder, and when the tightening block is tightened, the rubber layer on its arc surface can increase the friction between it and the cylinder to ensure the stability of its angle. The cylinder 4 includes a smooth portion close to the side of the frame 1 and a knurled portion away from the side of the frame 1. The smooth portion is used to cooperate with the rotation connection support frame, and the knurled portion is used to operate the cylinder to drive the rotation of the entire clamping telescopic assembly.

[0034] Finally, in order to make the entire device able to be placed stably, a finished fixed base can be installed and mechanically fixed to the saddle connecting rod. According to the site of use, the corresponding fixed base can be selected so that the entire device can be rooted through suitable forms such as pipe clamps, magnets, clamps, and floor bases.

[0035] In summary, the operating principle of this device is:

[0036] 1. Open or remove the two sets of figure-eight elastic bands to increase the gap between the two clamping wheels.

[0037] 2. Pass the flexible insertion tube of the pipeline endoscope or remote foreign body salvage device through the cylinder on one side of the frame, the telescopic hole on one side of the frame, the middle of the arc grooves of the two clamping wheels, the telescopic hole on the other side of the frame, and the cylinder on the other side of the frame.

[0038] 3. Restore the two sets of figure-eight elastic bands to their original state or reassemble them. The tightening force will reduce the gap between the two clamping wheels. The clamping wheels will clamp the flexible insertion tube, and the arc groove of the clamping wheels will be in moderate contact with the flexible insertion tube.

[0039] 4. Rotate the knob at the end of the clamping wheel shaft to drive the two clamping wheels to rotate in opposite directions. The friction generated by clamping makes the flexible insertion tube move forward and backward. At this time, the direction, angle, and speed of the knob rotation can be changed to control the forward and backward direction, insertion distance, and insertion speed of the flexible insertion tube.

[0040] 5. Loosen the tightening screw and rotate the cylinder to rotate the clamping telescopic assembly relative to the support frame. The clamped flexible insertion tube will also rotate with the clamping telescopic assembly. At this time, the direction, angle, and speed of rotation of the clamping telescopic assembly can be changed to control the rotation direction, rotation angle, and rotation angular velocity of the flexible insertion tube. The tightening screw can be rotated to adjust the degree of compression of the clamping block on the cylinder to change the damping value of the rotation or lock the rotation at the target angle.

[0041] The above is only a preferred specific embodiment of the present invention, which is an implementation method based on the overall concept of the present invention, and the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
