Description

Technical Field

[0001] The utility model relates to the technical field of acoustic imaging devices, in particular to a detection device. Background Art

[0002] Acoustic imaging logging technology plays a vital role in fields such as petroleum and geological exploration. As a key component for collecting downhole geological information, the performance and integrity of the acoustic imaging logging instrument's probe directly impact the accuracy and reliability of the logging data. However, as exploration progresses and geological conditions become increasingly complex, the harsh internal environment, accompanied by large amounts of dust or mud coating the probe surface, often requires removal for maintenance and cleaning, making it cumbersome and inconvenient to use.

[0003] The detection device in the existing technology usually has a support plate on the probe, and then a cylinder parallel to the probe is installed on the support plate. Each probe corresponds to one or two cylinders. The cleaning brush is moved up and down by the extension and contraction of the cylinder rod to clean the dust and mud attached to the probe.

[0004] However, in real-world exploration, multiple probes are typically installed to ensure accurate and reliable information. If each probe requires one or two cylinders for cleaning, the entire detection device becomes more complex and cleaning efficiency decreases. Furthermore, the complexity of the detection device increases the difficulty of inserting the entire device into the well, requiring the expansion of the wellhead and downhole area when necessary, thus increasing the workload. Therefore, developing a detection device with a simple structure and efficient probe cleaning capabilities is particularly important. Utility Model Content

[0051] In the description of the present utility model, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first feature and the second feature being in direct contact, or may include the first feature and the second feature being in contact not directly but through another feature between them.

[0052] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0053] like Figure 1-Figure 5 As shown, the present invention provides a detection device, including a housing assembly 1, a support frame 2, a cleaning assembly 3 and a driving mechanism 4. A plurality of probes 100 are distributed along a first direction on the housing assembly 1, the support frame 2 is movably connected to the housing assembly 1 along the first direction, the cleaning assembly 3 is connected to the support frame 2, and the cleaning assembly 3 includes a cleaning brush 31. The driving mechanism 4 is provided on the housing assembly 1 and can drive the support frame 2 to move relative to the housing assembly 1 along the first direction. When the support frame 2 moves relative to the housing assembly 1, the cleaning brush 31 can scrape and clean the plurality of probes 100 in sequence. In the present invention, a shell assembly 1, a support frame 2, a cleaning assembly 3 and a driving mechanism 4 are set, and multiple probes 100 are distributed in the first direction of the shell assembly 1, the support frame 2 is movably connected to the shell assembly 1, and the driving mechanism 4 can drive the support frame 2 to move relative to the shell assembly 1 along the first direction. Since the cleaning assembly 3 is connected to the support frame 2, and the cleaning assembly 3 includes a cleaning brush 31, when the support frame 2 slides relative to the shell assembly 1, the cleaning brush 31 can scrape and clean multiple probes 100 in turn, thereby achieving the purpose of one cleaning brush 31 being able to clean multiple probes 100, with high cleaning efficiency, and the structure of the entire detection device is simpler, which is more convenient for working deep underground in actual use.

[0054] Specifically, if Figure 1-Figure 2 As shown, multiple probes 100 are sequentially arranged along the circumference of the housing component 1 , an annular slide 5 is provided on the housing component 1 , and the support frame 2 is slidably arranged on the annular slide 5 and can move along the circumference of the housing component 1 .

[0055] like Figure 1-Figure 2As shown, a bottom probe for detecting the bottom environment of the well is installed at the bottom of the housing assembly 1. Due to gravity, the bottom probe is not easily covered with dust. However, the probes 100 arranged along the circumference of the housing assembly 1 for detecting the well wall environment are easily covered with dust. Therefore, only the probes 100 arranged along the circumference of the housing assembly 1 need to be cleaned, which is more targeted. At the same time, the provision of the annular slide 5 ensures that the support frame 2 can move stably and accurately around the circumference of the housing assembly 1.

[0056] In other embodiments, the first direction may be not only the circumferential direction of the housing assembly 1 but also a linear direction on the housing assembly 1. In this case, multiple probes 100 are arranged along a straight line on the housing assembly 1, and the support frame 2 moves along a straight line on the housing assembly 1.

[0057] In other embodiments, a bearing ring may be further provided on the housing assembly 1 , and the support frame 2 is connected to the bearing ring. The rotation of the bearing ring drives the support frame 2 to move circumferentially along the housing assembly 1 .

[0058] Specifically, if Figure 2-Figure 3 As shown, the drive mechanism 4 includes a drive motor 41 and a driving wheel 42. The drive motor 41 is mounted on the housing assembly 1, and the driving wheel 42 is connected to the output terminal of the drive motor 41 and is in transmission connection with the support frame 2. Since the drive motor 41 and the driving wheel 42 are directly mounted on the housing assembly 1, they do not occupy excessive space, making the structure of the entire device more compact. Secondly, the drive motor 41 can achieve precise speed and direction control by controlling current, voltage, or pulse signals, thereby accurately controlling the movement speed and direction of the support frame 2, and the transmission efficiency is also improved.

[0059] More specifically, if Figure 3 As shown, the support frame 2 is provided with an internal gear ring 6, and the driving wheel 42 is a gear that meshes with the internal gear ring 6. When the drive motor 41 is in operation, it drives the driving wheel 42 to rotate, and the gear meshes with the internal gear ring 6 on the support frame 2. The rotation of the gear drives the internal gear ring 6 to move. The meshing transmission between the gear and the internal gear ring 6 enables precise position control. At the same time, the meshing transmission between the gear and the internal gear ring 6 can adapt to the high-temperature and high-pressure working environment underground, and maintains excellent transmission performance.

[0060] In this embodiment, the support frame 2 and the inner ring gear 6 are both annular, and the support frame 2 and the outer shell assembly 1 are arranged to form an inner cavity. The inner ring gear 6 is connected to the inner side of the support frame 2 and is located in the inner cavity. The drive motor 41 is located in the outer shell assembly 1, and its output shaft extends into the outer shell assembly 1 and is connected to the driving wheel 42. A sealing ring is sandwiched between the output shaft of the drive motor 41 and the inner wall of the outlet hole thereof.

[0061] In other embodiments, the driving wheel 42 may also directly abut against the support frame 2 to drive the support frame 2 to move through friction.

[0062] Specifically, if Figure 2 As shown, the cleaning assembly 3 also includes a cleaning bracket 32 ​​and a position detector 33. The cleaning bracket 32 ​​is connected to the support frame 2, and the cleaning brush 31 is mounted on the cleaning bracket 32; the position detector 33 is mounted on the cleaning bracket 32 ​​and is used to detect the position of the cleaning bracket 32 ​​relative to the probe 100. The cleaning bracket 32 ​​provides a mounting platform for the cleaning brush 31, so that the cleaning brush 31 can contact the probe 100 at a suitable angle and position for cleaning. At the same time, during the cleaning process, when the cleaning bracket 32 ​​approaches the probe 100, the position detector 33 can trigger the cleaning brush 31 to start working; when the cleaning bracket 32 ​​leaves the probe 100, the position detector 33 can notify the control system to stop the cleaning brush 31, thereby achieving accurate cleaning of the probe 100 and improving cleaning efficiency.

[0063] In this embodiment, the position detector 33 is a photoelectric position detector. The photoelectric position detector continuously emits and receives light signals. When the cleaning bracket 32 ​​moves with the support frame 2, the photoelectric position detector moves with the cleaning bracket 32. When the photoelectric position detector detects the presence of the probe 100, the frequency of the reflected light will change. The photoelectric position detector converts the detected light signal change into an electrical signal and transmits it to the control system. The control system analyzes and processes the electrical signal to determine whether the probe 100 is detected. During the cleaning process, the photoelectric position detector continuously detects the relative position of the cleaning bracket 32 ​​and the probe 100. If the cleaning bracket 32 ​​moves away from the probe 100, the photoelectric position detector will detect the change in the light signal. When the cleaning bracket 32 ​​approaches the probe 100 again, the photoelectric position detector will re-detect the presence of the probe 100, thereby improving the cleaning efficiency while protecting the safety of the probe 100. After the cleaning operation is completed, it can stop at a safe position to avoid interference and obstruction of the probe 100 during operation.

[0064] Specifically, if Figure 2As shown, the detection device also includes a controller 7 and a temperature detector 8. A housing cavity 200 is provided in the housing component 1, and the controller 7 is provided in the housing cavity 200. Each probe 100 partially extends into the housing cavity 200 and is connected to the controller 7 through communication. The temperature detector 8 is provided in the housing cavity 200 for detecting the temperature in the housing cavity 200. The controller 7 can control the start and stop of the probe 100. When the temperature detector 8 detects that the temperature in the housing cavity 200 reaches a limit value, it sends a circuit breaker signal to the controller 7. When the controller 7 receives the circuit breaker signal from the temperature detector 8, it controls the probe 100 to stop working, so as to prevent excessive temperature from damaging the probe 100, affecting the measurement accuracy of the probe 100, or even causing the probe 100 to completely fail, thereby ensuring that the probe 100 can operate stably and accurately in a complex working environment and obtain high-quality detection data.

[0065] In this embodiment, the drive motor 41 is also connected to the controller 7, and the controller 7 can control the start and stop of the drive motor 41. When the temperature in the accommodating chamber 200 reaches a limit value, the controller 7 shuts down the probe 100 and starts the drive motor 41 to start working. At this time, the support frame 2 can drive the cleaning bracket 32 ​​and the cleaning brush 31 to move relative to the outer shell assembly 1 under the drive of the driving mechanism 4, so as to clean the dust or mud on the surface of the probe 100 in time.

[0066] In this embodiment, the controller 7 and the temperature detector 8 are conventional electrical components in the art, and their circuit connection relationship and working method are conventional settings, which will not be described in detail here.

[0067] Specifically, if Figure 4 As shown, the accommodating cavity 200 includes a first cavity 2001 and a second cavity 2002, the first cavity 2001 and the second cavity 2002 are connected through an intermediate channel 2003, the controller 7 is arranged in the first cavity 2001, the temperature detector 8 is arranged in the second cavity 2002, and the probe 100 partially extends into the second cavity 2002, each of the probes 100 is connected to the controller 7 through a wire, and a guide protective tube 9 is provided on the outside of each wire, and a partition block 10 is provided in the intermediate channel 2003, and the guide protective tube 9 passes through the partition block 10.

[0068] The accommodating chamber 200 is divided into a first cavity 2001 and a second cavity 2002, which are connected by an intermediate passage 2003, so that different components can function in relatively independent spaces, improving the stability and reliability of the system. The controller 7 is arranged in the first cavity 2001 to prevent it from being interfered with by the probe 100 or other components, ensuring that the operation of the probe 100 can be accurately stopped when needed. The temperature detector 8 is arranged in the second cavity 2002, which can more directly detect temperature changes in the area where the probe 100 is located. The probe 100 partially extends into the second cavity 2002, and the temperature detector 8 can more accurately reflect the temperature conditions around the probe 100. Once the temperature reaches the limit value, it can promptly send a circuit breaker signal. The guide protection tube 9 sheathed on the outside of each wire plays a role in protecting the wire and preventing the wire from being damaged in a complex working environment. The partition block 10 in the intermediate passage 2003 not only plays the role of fixing the guide protection tube 9 to ensure the stable position of the wire, but also further separates the different cavities, reducing the mutual influence between different components.

[0069] In other embodiments, each probe 100 and the controller 7 can also be connected wirelessly, such as by Bluetooth. In this case, there is no need to set up the guide protection tube 9, and it is only necessary to separate the first cavity 2001 and the second cavity 2002 by the partition block 10.

[0070] Specifically, if Figure 1-Figure 2 As shown, the housing assembly 1 is provided with an installation port connected to the accommodating chamber 200, and a sealing cover 11 is provided at the installation port. On the one hand, the setting of the installation port provides a convenient passage for installing the probe 100, controller 7, temperature detector 8 and other components into the accommodating chamber 200. During the assembly, maintenance and overhaul of the equipment, the staff can operate the various components in the accommodating chamber 200 by opening the sealing cover 11, which reduces the difficulty of maintenance. On the other hand, the sealing cover 11 plays a sealing role. In the well logging environment, various harsh conditions such as high temperature, high pressure, humidity, corrosive substances, etc. are usually encountered. The sealing cover 11 can effectively prevent external dust, moisture, corrosive gases, etc. from entering the accommodating chamber 200, protecting the internal components such as the probe 100, controller 7 and temperature detector 8 from damage.

[0071] In this embodiment, the shell assembly 1 includes a first shell and a second shell, the first cavity 2001 is arranged in the first shell, the second cavity 2002 and the intermediate channel 2003 are arranged in the second shell, the mounting port is connected to the first cavity 2001, and is arranged on the side of the first shell facing away from the second shell, and annular slides 5 are respectively provided on the opposite sides of the first shell and the second shell, and the support frame 2 is clamped between the two annular slides 5, so that the sliding is more balanced and reliable.

[0072] More specifically, if Figure 4-Figure 5As shown, the sealing cover 11 is provided with an annular sealing mechanism 12, and the inner wall of the accommodating cavity 200 is provided with an annular connecting block 13. An annular receiving groove is provided on the annular connecting block 13. The sealing cover 11 is screwed to the outer shell component 1, and the annular sealing mechanism 12 extends into the annular receiving groove. The screw connection can provide a greater connection force, ensuring that the sealing cover 11 can be firmly fixed to the outer shell component 1. At the same time, the installation can be completed by a rotation operation, which greatly improves the efficiency and convenience of installation and facilitates subsequent disassembly and maintenance. The cooperation between the annular sealing mechanism 12 and the annular receiving groove also further enhances the stability of the connection between the sealing cover 11 and the outer shell component 1, preventing the sealing cover 11 from loosening or falling off when subjected to external impact or vibration.

[0073] More specifically, if Figure 5 As shown, the sealing cover 11 is provided with a first hook member 14, and the annular connecting block 13 is provided with a second hook member 15. The first hook member 14 is hooked on the second hook member 15 to form a mechanical locking structure. Even when the screw connection is loose to a certain extent, the first hook member 14 is hooked on the second hook member 15 to play a certain sealing role, ensuring that the sealing cover 11 always remains in the correct position and the sealing of the accommodating cavity 200 is guaranteed.

[0074] In this embodiment, if Figure 5 As shown, the first hook member 14 is a C-shaped card plate provided on the sealing cover 11, the annular sealing mechanism 12 is provided on the first hook member 14, and two second hook members 15 are provided on the annular connecting block 13. During installation, the first hook member 14 can cross the gap between the two second hook members 15, and then move on the inner side of the two second hook members 15 during the rotation of the sealing cover 11.

[0075] Specifically, if Figure 5 As shown, the annular sealing mechanism 12 includes a support block 121, a sealing plate 122 and an elastic member 123. The support block 121 is connected to the first hook member 14. The support block 121 and the sealing plate 122 are both annular. The sealing plate 122 is coaxially connected to the support block 121 and can slide along the axis of the support block 121 and extend into the annular receiving groove. A plurality of elastic members 123 are provided, which are respectively clamped between the support block 121 and the sealing plate 122.

[0076] In this embodiment, the elastic member 123 is a spring. When sealing, the sealing cover 11 is inserted into the accommodating cavity 200 from the installation port. At this time, the sealing plate 122 is just inserted into the annular receiving groove of the annular connecting block 13. The rotating sealing cover 11 drives the first hook member 14 to rotate together. At the same time, the first hook member 14 is hooked on the second hook member 15 to limit the position. During the rotation, the support block 121 squeezes multiple elastic members 123, so that the sealing plate 122 is tightly against the bottom of the annular receiving groove, thereby improving the sealing performance of the detection device. At this time, the elastic member 123 can absorb and disperse part of the pressure, so that the sealing plate 122 is subjected to more balanced force.

[0077] In other embodiments, the elastic member 123 may also be an elastic rubber pad or the like. In other embodiments, the annular sealing mechanism 12 may also be directly an elastic sealing ring.

[0078] Specifically, if Figure 4-Figure 5 As shown, a heat insulation plate 16 is provided in the first cavity 2001, and a closed cavity is formed between the heat insulation plate 16 and the outer shell assembly 1. Heat insulation silicone oil is provided in the cavity to prevent high temperature from damaging the function of the controller 7, so that the controller 7 in the first cavity 2001 is better protected, thereby effectively controlling the use or disconnection of the probe 100.

[0079] In this embodiment, the annular connecting block 13 is connected to the inner wall of the heat insulation board 16 , and an annular receiving groove is formed between the annular connecting block 13 and the inner wall of the heat insulation board 16 .

[0080] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
