Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline shaft construction, and particularly relates to an azimuth video logging instrument. Background Art

[0002] Downhole video logging instruments are used to directly observe the downhole conditions of wellbores. During coal mining, the surface gas mining wells serving coal mine downhole gas control are affected by mining, and the well pipes often break or are misaligned. In order to study the fracture mechanism of well pipes, it is necessary to conduct in-well peeping imaging of well pipes to obtain the damaged positions and conditions of well pipes, so as to study the stress direction of well pipes and the movement law of surrounding rocks. However, due to the relatively humid downhole environment and a large amount of mud, the mud is easily attached to the lens, which in turn affects the imaging effect. Now, a structure capable of cleaning the lens is proposed. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides an azimuth video logging instrument to solve the above problems.

[0012] Beneficial effects

[0013] The present invention provides an azimuth well logging instrument, which has the following beneficial effects compared with the prior art:

[0014] 1. During the process of the lens descending in the pipe shaft, if the probe is blocked, the user starts the motor at this time, so that the shaft fixedly connected to its output shaft starts to rotate, and drives the gear fixedly connected to the other side to rotate synchronously. Then, the gear ring starts to drive the cylinder fixedly connected to it to rotate under the cooperation of the gear meshed with it. When the probe slides upward, since the probe is in close contact with the lining ring, the soil on the side wall of the probe can be scraped onto the cylinder. Thus, the centrifugal force generated by the high-speed rotation of the cylinder can throw the soil on it away, and then initially remove the large pieces of soil on the side wall of the probe. At the same time, when the cylinder rotates, the gear ring A fixedly connected to it rotates synchronously to drive the multiple meshed gears B to rotate uniformly. Then, the guide rods fixedly connected to the centers of the multiple gears B start to rotate synchronously, and drive the cotton cylinders fixedly connected to them to rotate. Thus, the probe is wiped by the rotation of the cotton cylinders to further remove the mud stains on it. At the same time, after the large mud stains on the probe are removed and wiped by the rotation of multiple gear rings, the cleaning fineness can be effectively improved, and a large amount of soil can be prevented from being smeared on the cotton cylinders, resulting in the subsequent cleaning being affected;

[0015] When the shaft starts to rotate, the lead screw fixedly connected to it rotates synchronously, and drives the sliding disk threaded thereon, so that the sliding disk starts to slide upward along its connection with the frame. Then, the probe fixedly connected to the center of the sliding disk starts to slide synchronously, driving the probe to slide into the cylinder. At this time, since the lining ring is attached to the probe through the sealing strip, the soil attached to the side wall of the probe starts to be scraped to the bottom of the cylinder, and the soil on it is thrown away by the rotation of the cylinder. At the same time, since the connecting disk B and the connecting disk A are both rotatably arranged on the cylinder, they will not affect the rotation of the cylinder;

[0016] 2. At the same time, during the upward movement of the sliding disk, the multiple connecting rods fixedly connected to it start to slide synchronously, and through the joints fixedly connected to their bottoms, the piston rod is pushed into the liquid collecting cylinder. By the relative sliding of the piston rod in the liquid collecting cylinder, the liquid in the liquid collecting cylinder is discharged into the cylinder through the pipeline connected to the connecting disk A through the circulating pipeline, and under the action of the pressure of the piston rod, the liquid is pressurized and sprayed on the cotton cylinder and the probe. At the same time, since a sealing rubber ring is provided at the connection between the probe and the lining ring, it can effectively prevent the liquid from leaking out, so that the liquid can be collected at the bottom of the cylinder, and then humidify the probe to soften the soil on it, so that the cotton cylinder can quickly wipe the soil on it, and can effectively clean the soil attached to the cotton cylinder, thus preventing the soil from being coated on the probe again;

[0017] 3. When the sliding plate rises to the top of the lead screw, the liquid in the liquid collecting cylinder is completely drained into the cylinder body. At the same time, the piston rod contacts the magnet cover plate, and then the magnet cover plate is adsorbed and connected to the piston rod. At this time, the side wall of the lens is cleaned. The user can reverse-start the motor, and then the probe starts to extend out of the cylinder body. At the same time, the piston rod slides reversely in the liquid collecting cylinder synchronously, and then the liquid collected at the bottom of the cylinder body is sucked into the liquid collecting cylinder. At the initial state, the magnet cover plate blocks the filter cylinder, and the mesh holes on the filter cylinder are all above the pipe orifice of the liquid collecting cylinder. At the same time, the user should start the operation to make the filter cylinder slide into the liquid collecting cylinder, so as to block the opening of the liquid collecting cylinder through the top cover plate of the filter cylinder. Therefore, it will not affect the airtightness of the liquid collecting cylinder, so that the liquid collecting cylinder can normally suck the liquid in the cylinder body. After the piston rod slides back to its original position, the user continues to start motor B, and then the collar starts to drive the filter cylinder to slide downwards, so that the filter cylinder enters the liquid collecting cylinder. During this process, the filter cylinder can filter the liquid in the connecting frame, filter the sediment into it, and when the filter cylinder contacts the magnet cover plate, the filter cylinder can be inserted tightly on the magnet cover plate through the collar, so that they are tightly connected, and then the sediment is sealed in the filter cylinder. Subsequently, the user can reverse-start motor B, so that the filter cylinder starts to slide back to its original position, that is, the filtration of the water in the liquid collecting cylinder is completed, so as to facilitate the cleaning of the lens again.

Detailed implementation manners

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention 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 only used to explain the present invention and are not used to limit the present invention.

[0027] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0028] Please refer to Figure 1 and Figure 3 , which is provided for an embodiment of the present invention. An azimuthal well logging instrument includes a probe 101 and further includes:

[0029] A cleaning assembly 2 for cleaning the soil on the lens;

[0030] The cleaning assembly 2 includes a lining ring 201, a cylinder 202, a gear ring 203, a gear 204, a shaft 205 and a frame 206. The two lining rings 201 are symmetrically and slidably connected to the probe 101, and the lining ring 201 is attached to the probe 101 through the rubber strip on its inner wall. The cylinder 202 is rotatably connected to the lining ring 201. The gear ring 203 is fixedly connected to the top of the cylinder 202. The gear 204 is meshed with the gear ring 203. The shaft 205 is fixedly connected to the center of the gear 204. The shaft 205 is rotatably connected to the frame 206. The probe 101 passes through the central through hole of the frame 206. The frame 206 is rotatably connected to the cylinder 202.

[0031] Please refer to Figure 2 , specifically, the top of the shaft 205 is fixedly connected to the output shaft of the motor 207. The motor 207 is fixedly connected to the frame 206. The top of the sliding disk 302 is fixedly connected to a cable 208 for pulling the probe 101 into the pipeline well.

[0032] Please refer to Figure 2 and Figure 7, specifically, a gear ring A209 is fixedly connected to the inner bottom of the cylinder body 202. The gear ring A209 is meshed and connected with a gear B2001. A guide rod 2002 is fixedly connected to the axis of the gear B2001. The guide rod 2002 is fixedly connected to a cotton cylinder 2003. The guide rod 2002 is rotatably connected between two lining rings 201. The cotton cylinder 2003 is used for brushing the lens.

[0033] In the embodiment of the present invention, during the process of the lens descending in the pipe shaft, if the probe 101 is blocked, the user starts the motor 207 at this time, so that the shaft 205 fixedly connected to its output shaft starts to rotate, and drives the gear 204 fixedly connected to the other side thereof to rotate synchronously. Then, at this time, the gear ring 203 starts to drive the cylinder body 202 fixedly connected to it to rotate under the cooperation of the gear 204 meshed with it. Thus, when the probe 101 slides upward, since the probe 101 is in close contact with the lining ring 201, the soil on the side wall of the probe 101 can be scraped onto the cylinder body 202. Then, the centrifugal force generated by the high-speed rotation of the cylinder body 202 can be used to throw off the soil on it, thereby initially removing the large pieces of soil on the side wall of the probe 101. At the same time, when the cylinder body 202 rotates, the gear ring A209 fixedly connected to it rotates synchronously to drive the multiple meshed gear B2001 to rotate at a uniform speed. Then, at this time, the guide rods 2002 fixedly connected to the axes of the multiple gear B2001 start to rotate synchronously, and drive the cotton cylinders 2003 fixedly connected to them to rotate. Thus, the probe 101 is rotationally wiped by the rotation of the cotton cylinder 2003, thereby further removing the stains on it. At the same time, after the large pieces of stains on the probe 101 are removed and then wiped by the rotation of the multiple gear rings 203, the cleaning fineness can be effectively improved, and a large amount of soil can be prevented from being applied to the cotton cylinder 2003, resulting in the subsequent cleaning being affected.

[0034] Please refer to Figure 3 and Figure 4 , specifically, the humidifying component 3 includes a lead screw 301, a sliding disk 302, a connecting rod 303, a joint 304, a piston rod 305 and a liquid collecting cylinder 306. The lead screw 301 is fixedly connected to the shaft 205. The sliding disk 302 is threadedly connected to the lead screw 301. One end of the connecting rod 303 is fixedly connected to the sliding disk 302. The other end of the connecting rod 303 is fixedly connected to the joint 304. The piston rod 305 is fixedly connected to the joint 304. The piston rod 305 is slidably connected in the liquid collecting cylinder 306 and is used to discharge the cleaning liquid in the liquid collecting cylinder 306.

[0035] Please refer to Figure 4 and Figure 6, specifically, the liquid collection cylinder 306 is fixedly connected to the connecting disk B309, the connecting disk B309 is rotatably connected to the cylinder body 202, a circulation pipeline 307 is fixedly connected to the liquid collection cylinder 306, the other end of the circulation pipeline 307 is fixedly connected to the connecting disk A308, the connecting disk A308 is rotatably connected to the cylinder body 202, and a pipeline corresponding to and communicating with the circulation pipeline 307 is provided in the connecting disk A308 for spraying liquid into the cylinder body 202.

[0036] In the embodiment of the present invention, when the shaft 205 starts to rotate, the screw rod 301 fixedly connected thereto rotates synchronously, and drives the sliding disk 302 threadedly connected thereto, so that the sliding disk 302 starts to slide upward along the connection part between it and the frame 206. At this time, the probe 101 fixedly connected to the center of the sliding disk 302 starts to slide synchronously, thereby driving the probe 101 to start sliding into the cylinder body 202. At this time, since the lining ring 201 is attached to the probe 101 through a sealing strip, the soil attached to the side wall of the probe 101 at this time starts to be scraped to the bottom of the cylinder body 202, and the soil on it is thrown off by the rotation of the cylinder body 202. At the same time, since both the connecting disk B309 and the connecting disk A308 are rotatably arranged on the cylinder body 202, it will not affect the rotation of the cylinder body 202;

[0037] At the same time, during the upward movement of the sliding disk 302, the multiple connecting rods 303 fixedly connected thereto start to slide synchronously, and through the joint 304 fixedly connected to the bottom thereof, the piston rod 305 is pushed into the liquid collection cylinder 306. By the relative sliding of the piston rod 305 in the liquid collection cylinder 306, the liquid in the liquid collection cylinder 306 is discharged into the cylinder body 202 through the pipeline communicating with the connecting disk A3080 of the circulation pipeline 307, and under the action of the pressure of the piston rod 305, the liquid is pressurized and sprayed on the cotton cylinder 2003 and the probe 101. At the same time, since a sealing rubber ring is provided at the connection between the probe 101 and the lining ring 201, it can effectively prevent the liquid from leaking out, so that the liquid can be collected at the bottom of the cylinder body 202, and then the probe 101 is humidified to soften the soil on it, so that the cotton cylinder 2003 can quickly wipe the soil on it, and can effectively clean the soil attached to the cotton cylinder 2003, thereby preventing the soil from being coated on the probe 101 again.

[0038] Please refer to Figure 5 and Figure 6 , specifically, the filtering assembly 4 includes a filter cylinder 401, a magnet cover plate 402 and a ring sleeve 403. The filter cylinder 401 is sleeved in the liquid collection cylinder 306 with the opening facing downwards, and a plurality of mesh holes are symmetrically arranged on the upper half part of the tube body of the filter cylinder 401. The magnet cover plate 402 is inserted into the filter cylinder 401, the magnet cover plate 402 is magnetically adsorbed and connected to the piston rod 305, the magnet cover plate 402 is connected to the filter cylinder 401 in the initial state, and a ring sleeve 403 is fixedly connected to the top of the filter cylinder 401.

[0039] Please refer to Figure 4 and Figure 5 Specifically, the collar 403 is threadedly connected to the lead screw 404. The collar 403 is slidably connected to the connection frame 405. One end of the lead screw 404 is rotatably connected to the connection frame 405. The other end of the lead screw 404 is fixedly connected to the output shaft of the motor B406. The motor B406 is fixedly connected to the connection disk A308.

[0040] In the embodiment of the present invention, when the sliding disk 302 rises to the top of the lead screw 301, at this time, the liquid in the liquid collecting cylinder 306 is completely discharged into the cylinder body 202. At the same time, the piston rod 305 contacts the magnet cover plate 402, and then the magnet cover plate 402 and the piston rod 305 are adsorbed and connected together. At this time, the side wall of the lens is completed for cleaning. The user can reversely start the motor 207. Then, the probe 101 starts to extend out of the cylinder body 202. At the same time, the piston rod 305 slides reversely in the liquid collecting cylinder 306 synchronously, and then sucks the liquid collected at the bottom of the cylinder body 202 into the liquid collecting cylinder 306. At the same time, since the magnet cover plate 402 seals the filter cylinder 401 in the initial state, and the mesh holes on the filter cylinder 401 are all above the nozzle of the liquid collecting cylinder 306. At the same time, the user should start 406 to make the filter cylinder 401 slide into the liquid collecting cylinder 306, so as to block the opening of the liquid collecting cylinder 306 through the top cover plate of the filter cylinder 401. Therefore, it will not affect the airtightness of the liquid collecting cylinder 306, so that the liquid collecting cylinder 306 can normally suck the liquid in the cylinder body 202. When the piston rod 305 slides back to its original position, the user continues to start the motor B406. Then, the collar 403 starts to drive the filter cylinder 401 to slide downwards, so that the filter cylinder 401 enters the liquid collecting cylinder 306. During this process, the filter cylinder 401 can filter the liquid in the connection frame 405, filter the sediment into it, and when the filter cylinder 401 contacts the magnet cover plate 402, the filter cylinder 401 can be inserted tightly on the magnet cover plate 402 through the collar 403, so that they are tightly connected, and then the sediment is sealed in the filter cylinder 401. Subsequently, the user can reversely start the motor B406, so that the filter cylinder 401 starts to slide back to its original position, that is, the filtration work of the water in the liquid collecting cylinder 306 is completed, so as to facilitate the cleaning of the lens again.

[0041] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0042] The fixed connection referred to in this application means a connection where parts or components are fixed without any relative movement. It is divided into two types: detachable connection and non-detachable connection.

[0043] (1) Detachable connection: Use screws, splines, wedge pins, etc. to fix components together. This connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedge pins), and they must be tightened properly.

[0044] (2) Non-detachable connection: mainly refers to welding, riveting, and mortise joint fitting, etc. Since it requires forging, sawing, or oxygen cutting to disassemble during maintenance or replacement, the spare parts generally cannot be used a second time. At the same time, during connection, attention should be paid to process quality, technical inspection, and remedial measures (such as correction, polishing, etc.).

[0045] The sliding connection referred to in this application means that a component can slide along a linear track, and the hinged connection referred to in this application means that a component can rotate along an axial constraint.

[0046] In some cases, the sliding connection and the hinged connection referred to in this application can also be damped, so that the component has the ability to maintain at the desired position.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
