Description

Technical Field

[0001] The invention relates to the technical field of image communication, in particular to a telescopic self-cleaning underground television. Background Art

[0002] Downhole television is a method of scanning along the wellbore with a television camera and monitoring changes in the well situation on the ground television screen. It uses digital image processing technology to digitize, segment and track the edges of downhole television images, thereby obtaining the geometric dimensions of the real objects in the television images. The downhole television system usually consists of two parts: ground instruments and downhole instruments. The ground instruments include television receivers, displays, control units, etc., which are used to receive, display and control image signals from downhole instruments.

[0003] Chinese patent publication number CN2384382Y discloses a visible light downhole television observation instrument. Although the application solves the problem of how the user can observe in real time from the display screen during the test process, and can go directly from the middle of the oil pipe or drill pipe to directly enable the operator to observe some engineering construction processes, it is useful for checking the operation effect and operation quality, improving the operation success rate, providing geological technicians with the production layer segment liquid production situation, re-understanding the oil layer, and checking the perforation quality. However, when the downhole television is put into use, the underwater probe is difficult to self-clean the surface, so that stains adhere to the surface of the camera, which will directly affect the imaging quality of the camera, causing the captured image to become blurred, making it difficult to clearly observe the actual situation downhole. Improvements need to be made to this problem. Summary of the invention

[0010] According to the above technical solution, the telescopic end of the electric telescopic rod passes through the fixed plate 1 and extends to the other side of the fixed plate 1 and is fixedly connected to the lifting ring. The middle part of the ball nut pair is threadedly connected to the outer side of the threaded column. The gear 1 and the gear 2 are located on the same horizontal line, and the gear 1 is meshed with the gear 2. When the gear 1 rotates, it is used to drive the gear 2 to rotate.

[0011] According to the above technical solution, the number of the threaded columns, ball nut pairs and gear one is two, and the two threaded columns, ball nut pairs and gear one are symmetrically distributed on both sides of the downhole probe, and the thread directions of the two threaded columns are opposite, unifying the rotation directions of the two gears one.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: in the present invention, after the downhole probe enters the well, since the well is divided into two situations, namely, above the liquid surface and below the liquid surface, when the downhole probe is located above the liquid surface, due to the presence of dust or oil mist in the well, it is difficult for the camera 1 to make a clear observation. At this time, the air stored in the airbag is ejected through the jet pipe connected to the pipe rack, which can disperse the air outside the camera 1, thereby avoiding the difficulty in observation caused by too much dust in the air outside the camera 1, so that the camera 1 can also work efficiently in places with much dust in the air. By observing the well wall, potential hidden dangers can be discovered in time, such as well wall rupture, filter pipe blockage, etc. If these hidden dangers are not discovered and handled in time, they may lead to the scrapping of the water well or oil well, or even cause safety accidents.

[0017] When the downhole probe enters the water in the well, when it is necessary to clean the outer side of the second camera, the cleaning cotton block is moved out from the outer wall of the downhole probe, so that the cleaning cotton block contacts the outer wall of the second camera, and as the second camera is controlled to rotate, the cleaning cotton block cleans the outer wall of the second camera. At this time, the downhole probe is in the water, and as the second camera rotates, the device can perform self-cleaning on the outer side of the second camera while working, and the stains that are difficult to clean and adhere to the outer surface of the second camera can be cleaned by washing with water;

[0018] When it is necessary to clean the outside of the camera 1, the electric telescopic rod is controlled to work, so that the ball nut pair rotates on the outside of the threaded column, and the cleaning rotating sleeve rotates in the protective sleeve. When the cleaning rotating sleeve covers the outside of the camera 1, the glass on the outside of the camera 1 is cleaned, which can prevent the mud on the surface from being adhered to by humid air and dust when the downhole probe is in the well, thereby ensuring that the glass on the outside of the camera 1 is clean and avoiding affecting the shooting of the camera 1.

[0019] By setting stabilizing blades, since the stabilizing blades are arranged on the outside of the downhole probe, when the downhole probe enters the water, the stabilizing blades on both sides unfold, which reduces the descending speed of the downhole probe in the water, making it more stable when observing the downhole situation. At the same time, since two stabilizing blades are arranged on the outside of the downhole probe, the center of gravity of the downhole probe in the water can be stably downward, and it is difficult to tilt due to external factors, and the stability is stronger in subsequent observations.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] For example, see Figure 1-7 The present invention provides a technical solution: a telescopic self-cleaning downhole television, comprising a television receiver 1, a driving component 6, a blowing component 7 and an auxiliary component 8. A signal connection line 2 is arranged on the outside of the television receiver 1, and a downhole probe 3 is fixedly connected to the end of the signal connection line 2 away from the television receiver 1. A camera 1 4 is arranged on the outside of the downhole probe 3, and a camera 2 5 is arranged on the end of the downhole probe 3 away from the signal connection line 2.

[0035] Wherein, the driving component 6 comprises:

[0036] A fixed disk 601 is fixedly connected to the outside of the downhole probe 3. An electric telescopic rod 602 is fixedly connected to the side of the fixed disk 601 close to the signal connection line 2. The electric telescopic rod 602 has a telescopic end. A lifting ring 604 is fixedly connected to the telescopic end of the electric telescopic rod 602. A threaded column 603 is fixedly connected to the side of the fixed disk 601 away from the signal connection line 2. A protective sleeve 608 is fixedly connected to the side of the lifting ring 604 away from the fixed disk 601. A cleaning rotating sleeve 609 is rotatably connected to the inside of the protective sleeve 608. A gear 2 607 is fixedly connected to the top of the cleaning rotating sleeve 609. A ball nut pair 605 is rotatably connected to the inside of the lifting ring 604. A gear 1 606 is fixedly connected to the top of the ball nut pair 605.

[0037] The blowing assembly 7 includes an airbag 701, a telescopic connecting tube 702, a connecting tube rack 703 and an injection tube 704. The airbag 701 is fixedly connected to the side of the fixed plate 2 610 away from the signal connection line 2, the telescopic connecting tube 702 is fixedly connected to the outside of the airbag 701, the connecting tube rack 703 is fixedly connected to the bottom of the lifting ring 604, and the injection tube 704 is fixedly connected to the bottom of the connecting tube rack 703.

[0038] When the lifting ring 604 moves, it squeezes the airbag 701, so that the air in the airbag 701 is transported to the connecting pipe frame 703 through the telescopic connecting pipe 702. At the same time, the air in the connecting pipe frame 703 is ejected through the jet pipe 704, which can disperse the air outside the camera 4 to avoid the dust in the air outside the camera 4, which makes it difficult to observe, so that the camera 4 can also work efficiently in places with a lot of dust in the air.

[0039] The telescopic end of the electric telescopic rod 602 passes through the fixed plate 1 601 and extends to the other side of the fixed plate 1 601 and is fixedly connected to the lifting ring 604. The middle part of the ball nut pair 605 is threadedly connected to the outer side of the threaded column 603. Gear 1 606 and gear 2 607 are located on the same horizontal line, and gear 1 606 and gear 2 607 are meshed and connected.

[0040] There are two threaded columns 603, two ball nut pairs 605 and two gears 606. The two threaded columns 603, the ball nut pairs 605 and the gears 606 are symmetrically distributed on both sides of the downhole probe 3, and the thread directions of the two threaded columns 603 are opposite.

[0041] A ventilation groove is provided in the lifting ring 604, and the connecting pipe frame 703 is connected to the ventilation groove. The end of the telescopic connecting pipe 702 away from the airbag 701 is fixedly connected to the outside of the lifting ring 604, and the telescopic connecting pipe 702 is connected to the ventilation groove.

[0042] A lifting groove is provided in the fixing plate 610 to accommodate the lifting of the extrusion arc plate 802. The end of the threaded column 603 away from the fixing plate 601 is fixedly connected to the fixing plate 610. The threaded column 603 and the airbag 701 are staggeredly arranged on one side of the fixing plate 601.

[0043] When the downhole probe 3 is working, as the downhole probe 3 descends, dust is mixed in the air outside the downhole probe 3. At this time, the electric telescopic rod 602 is controlled to work. When the electric telescopic rod 602 drives the lifting ring 604 to move, the ball nut pair 605 in the lifting ring 604 rotates in the threaded column 603 and moves synchronously.

[0044] When it is necessary to clean the outside of the camera 4, the electric telescopic rod 602 is controlled to work, so that the electric telescopic rod 602 drives the lifting ring 604 to move, and the ball nut pair 605 in the lifting ring 604 rotates on the outside of the threaded column 603. At the same time, when the ball nut pair 605 rotates, the gear 1 606 on the top of the ball nut pair 605 rotates accordingly. At this time, the gear 1 606 is meshed with the gear 2 607, so that the gear 1 606 drives the gear 2 607 to rotate. At this time, the cleaning rotating sleeve 609 on the gear 2 607 rotates in the protective sleeve 608. As the lifting ring 604 moves, the cleaning rotating sleeve 609 covers the outside of the camera 4. At the same time, when the cleaning rotating sleeve 609 rotates, the glass on the outside of the camera 4 is cleaned.

[0045] When it is necessary to monitor the underground, the underground probe 3 is placed underground. As the length of the signal connection line 2 placed underground gradually increases, the television receiver 1 controls the camera 1 4 and the camera 2 5 on the underground probe 3 to check the underground situation.

[0046] For example 2, please refer to Figure 1-11The present invention provides a technical solution: the auxiliary component 8 includes a connecting plate 801, an extruding arc plate 802, a guide frame 803, a fixed plate 804, a telescopic spring 805, an adjusting plate 806, a supporting arc plate 807, a storage spring 808, a rotating arc plate 809, a cleaning cotton block 810 and a positioning rotating frame 811, the connecting plate 801 is fixedly connected to the side of the protective sleeve 608 away from the lifting ring 604, the extruding arc plate 802 is fixedly connected to the end of the connecting plate 801 away from the protective sleeve 608, the guide frame 803 is fixedly connected to the side of the fixed plate 2 610 away from the lifting ring 604, and the adjusting plate 806 is slidably connected to the guide frame 803. In the inner middle part, the supporting arc plate 807 is fixedly connected to the side of the adjusting plate 806 away from the fixed disk 2 610, the storing spring 808 is fixedly connected to the side of the supporting arc plate 807 close to the camera 2 5, the rotating arc plate 809 is fixedly connected to the other end of the storing spring 808, the cleaning cotton block 810 is fixedly connected to the side of the rotating arc plate 809 away from the storing spring 808, the positioning rotating frame 811 is fixedly connected to the side of the adjusting plate 806 away from the fixed disk 2 610, the fixed plate 804 is fixedly connected to the side of the guide frame 803 away from the fixed disk 2 610, and the telescopic spring 805 is fixedly connected to the side of the adjusting plate 806 away from the fixed disk 2 610.

[0047] The rotating arc plate 809 is rotatably connected to the middle of the positioning rotating frame 811 at one side close to the adjusting plate 806 , and the telescopic spring 805 is fixedly connected to the adjusting plate 806 at one end away from the fixing plate 804 .

[0048] When the downhole probe 3 enters the water underground and the outside of the camera 2 5 needs to be cleaned, the electric telescopic rod 602 is controlled to drive the lifting ring 604 to descend. As the lifting ring 604 moves, the connecting plate 801 at the bottom of the lifting ring 604 pushes the extrusion arc plate 802 to pass through the lifting groove on the fixed disk 2 610 and move to the other side of the fixed disk 2 610, so that the extrusion arc plate 802 contacts the adjustment plate 806 and squeezes the adjustment plate 806 to apply force to the adjustment plate 806. At this time, the telescopic spring 805 is compressed to make the adjustment plate 806 slide in the guide frame 803. At this time, the cleaning cotton block 810 moves out from the outer wall of the downhole probe 3, so that the cleaning cotton block 810 and the camera 2 5 are cleaned. The outer side of the camera 25 is in contact with the cleaning cotton block 810, and as the outer side of the camera 25 is curved, the storage spring 808 is elastically restored. At this time, the rotating arc plate 809 rotates in the positioning rotating frame 811, and the cleaning cotton block 810 is close to and attached to the outer wall of the camera 25, so that the cleaning cotton block 810 is in contact with the outer wall of the camera 25. As the camera 25 is controlled to rotate, the outer wall of the camera 25 is in contact with the cleaning cotton block 810, so that the cleaning cotton block 810 cleans the outer wall of the camera 25. At this time, the downhole probe 3 is in the water, and as the camera 25 rotates, the device can perform self-cleaning on the outer side of the camera 25 while working, and clean the stains adhered to the outer surface of the camera 25.

[0049] It also includes a stabilizing component 9, which consists of a telescopic cylinder 901, a lifting member 902, a lifting block 903, a lifting frame 904, a lifting connecting plate 905, a stabilizing frame 906, a stabilizing blade 907 and a rotating adjustment frame 908. The telescopic cylinder 901 is fixedly connected to the outer side of the adjustment plate 806, and the telescopic cylinder 901 has a telescopic end. The lifting member 902 is fixedly connected to the telescopic end of the telescopic cylinder 901, the lifting block 903 is fixedly connected to the middle of the lifting member 902, the lifting frame 904 is fixedly connected to the top of the lifting block 903, the lifting connecting plate 905 is rotatably connected to the inner middle of the lifting frame 904, the stabilizing frame 906 is rotatably connected to the other side of the lifting connecting plate 905, the stabilizing blade 907 is fixedly connected to the top of the stabilizing frame 906, the rotating adjustment frame 908 is fixedly connected to the bottom of the fixed plate 2 610, and the stabilizing blade 907 is rotatably connected to the inner middle of the rotating adjustment frame 908.

[0050] When the adjustment plate 806 descends to clean the outside of 5, the telescopic cylinder 901 is synchronously driven to descend, so that the telescopic cylinder 901 is stretched, and at the same time, the lifting member 902 on the telescopic cylinder 901 descends, and the lifting block 903 on the outside of the lifting member 902 is controlled to descend synchronously, so that the lifting block 903 pulls the lifting connecting plate 905 through the lifting frame 904, and the lifting connecting plate 905 pulls the stabilizing frame 906. At this time, the stabilizing blades 907 on the stabilizing frame 906 rotate in the rotating adjustment frame 908 on the fixed disk 610, so that the stabilizing blades 907 fit the outside of the downhole probe 3, so as to avoid the stabilizing blades 907 causing greater resistance in the water during cleaning, thereby ensuring stable cleaning work.
