Description

Technical Field

[0001] This utility model belongs to the technical field of well inspection equipment, and in particular relates to a downhole endoscope imaging device. Background Technology

[0002] When conducting inspections or measurements inside a well, workers usually need to enter, which is labor-intensive and cannot be done when there is water. Furthermore, it's difficult to monitor the situation down inside the well in a timely manner, increasing the risk of accidents. Endoscopes can also be used for inspections or measurements.

[0003] Existing industrial endoscopes have a relatively simple structure, generally consisting of only a display and an imaging probe connected by a wire. In actual use, the probe is directly inserted into the well, and the image captured by the probe is transmitted to the display above. People can understand the situation down in the well by observing the image on the display. However, this structure cannot control the direction of the probe's image capture and can only passively observe the current position captured by the probe, resulting in low efficiency. Utility Model Content

[0005] This utility model is implemented as follows: a downhole endoscope imaging device includes a cylindrical waterproof frame, a servo motor is vertically fixedly connected inside the waterproof frame, the output shaft of the servo motor rotatably passes through the bottom end of the waterproof frame and extends outward, a rotating disk is fixedly connected to the outer end of the output shaft of the servo motor, extension plates are fixedly connected to both sides of the bottom end of the rotating disk, an imaging probe is rotatably connected between the two extension plates, and a reversing structure is provided on the top of the imaging probe.

[0006] Preferably, the reversing structure includes a driven gear fixedly connected to the top of the imaging probe, and an installation port is laterally opened on the outer surface of one of the extension pieces. An adjustment motor is fixedly connected inside the installation port, and a driving gear that meshes with the driven gear is fixedly connected to the inner end of the output shaft of the adjustment motor.

[0007] Preferably, a waterproof sleeve is fixedly connected to the top of the waterproof frame.

[0008] Preferably, the data cable and power cable of the imaging probe and the adjustment motor both pass through the interior of the waterproof sleeve and extend along its length.

[0009] Preferably, the central axes of the waterproof frame, the servo motor, the rotating disk, and the waterproof sleeve are located on the same straight line.

[0010] Preferably, the outer diameter of the driving gear is smaller than the outer diameter of the driven gear.

[0011] Beneficial effects

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The downhole endoscope imaging device of this utility model, by setting a servo motor and a reversing structure, allows the imaging probe to be directly sent into the well during use. After it is submerged in water, the tilt angle of the imaging probe can be changed by controlling the reversing structure. Then, the shooting direction of the imaging probe can be changed by controlling the operation of the servo motor.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a downhole endoscope imaging device, including a cylindrical waterproof frame 1, a servo motor is vertically fixedly connected inside the waterproof frame 1, the output shaft of the servo motor rotatably passes through the bottom end of the waterproof frame 1 and extends outward, a rotating disk 2 is fixedly connected to the outer end of the output shaft of the servo motor, extension pieces 3 are fixedly connected to both sides of the bottom end of the rotating disk 2, an imaging probe 4 is rotatably connected between the two extension pieces 3, and a reversing structure is provided on the top of the imaging probe 4.

[0019] The reversing structure includes a driven gear 5 fixedly connected to the top of the imaging probe 4, and an installation port that is laterally opened on the outer surface of an extension plate 3. An adjustment motor 6 is fixedly connected inside the installation port, and an active gear 7 that meshes with the driven gear 5 is fixedly connected to the inner end of the output shaft of the adjustment motor 6.

[0020] The central axes of the waterproof frame 1, servo motor, rotating disk 2, and waterproof sleeve 8 are located on the same straight line.

[0021] In this embodiment, when the device is in use, the imaging probe 4 is directly sent into the well. After it is submerged in the water, the tilt angle of the imaging probe 4 can be changed by controlling the direction-changing structure. Then, the shooting direction of the imaging probe 4 can be changed by controlling the operation of the servo motor. The two work together to allow the operator to control the imaging probe to shoot the required position, thereby improving the overall work efficiency.

[0022] When the servo motor is running, the rotation of its output shaft will drive the rotating disk 2, which is fixedly connected to the output shaft, to rotate. Then, it will synchronously drive the two extension plates 3 at the bottom of the rotating disk 2 to rotate, thereby changing the shooting direction of the imaging probe 4.

[0023] When the regulating motor 6 in the reversing structure is running, its output shaft rotates, and the driving gear 7 on the surface of the output shaft will drive the driven gear 5 to rotate, thereby driving the imaging probe 4, which is fixedly connected to the driven gear 5, to rotate, thereby changing the tilt angle of the imaging probe 4.

[0024] Furthermore, a waterproof sleeve 8 is fixedly connected to the top of the waterproof frame 1.

[0025] The data and power cables of the imaging probe 4 and the adjustment motor 6 are all inserted into the interior of the waterproof sleeve 8 and extend along its length.

[0026] In this embodiment, the waterproof sleeve 8 can collect and protect the circuits of various electronic devices in the device.

[0027] Furthermore, the outer diameter of the driving gear 7 is smaller than the outer diameter of the driven gear 5.

[0028] In this embodiment, the outer diameter of the driving gear 7 is smaller than that of the driven gear 5, which can reduce the speed of the imaging probe 4, thus making the adjustment more precise and stable.

[0029] The working principle and usage process of this utility model: After the utility model is installed, when using the device, the imaging probe 4 is directly sent into the well. After it is submerged in the water, the tilt angle of the imaging probe 4 can be changed by controlling the direction-changing structure. Then, the shooting direction of the imaging probe 4 can be changed by controlling the operation of the servo motor. The two work together to allow the staff to control the imaging probe to shoot the required position, thereby improving the overall work efficiency.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
