Description

Technical Field

[0001] This application relates to the technical field of drilling machines, and more particularly to an integrated sensor structure. Background Technology

[0002] In rotary drilling, sensors collect information such as the drill bit's rotation speed. In current technology, the sensors in the drill bit can only measure the inclination angle; conventional sensors are connected via cables and cannot store data.

[0003] During application, the pile hole is subjected to mineral corrosion, sand and gravel impact, and water pressure from a depth of over 100 meters.

[0004] Measuring the inclination of a pile hole requires the drill bit to rotate and descend. The advantage of rotating the drill bit compared to not rotating it is that it allows for a smoother descent, reducing friction and vibration between the drill bit and the hole wall, thus improving the accuracy of the sensor measurements. However, existing drill bits are affected by rotational acceleration during rotation, which, combined with the angle measurement principle of MEMS chips, causes angular deviations, leading to inaccurate measurements.

[0005] Existing pressure sensors have small contact surfaces, which are made of metal, resulting in significant errors and a short lifespan when detecting pressure inside pile holes.

[0006] Its shortcomings are: 1. It cannot accurately measure tilt angle, speed and pressure; 2. It has a short service life.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. Example 1:

[0034] This specification describes an integrated sensor structure, including: Protective cover section 1; The mounting part 2 is fixedly connected inside the protective cover part 1; The sensor part 3 is fixedly connected to the mounting part 2, and the sensor part 3 is fixedly connected to the protective cover part 1; The sensor unit 3 includes a housing unit 31 and a detection module. The detection module is fixedly connected to the housing unit 31 and is used to measure the X-axis tilt angle, Y-axis tilt angle, Z-axis rotation angle and pressure when the drill is working.

[0035] according to Figures 1 to 9Those skilled in the art can configure the drilling tool to have an integrated sensor structure, which is mainly composed of a protective cover 1, a mounting part 2 and a sensor part 3.

[0036] Specifically, those skilled in the art can configure the mounting part 2 to be fixedly connected to the inner wall of the protective cover part 1, thereby protecting the mounting part 2 through the protective cover part 1. Furthermore, the sensor part 3 can be fixedly connected to the mounting part 2, and the sensor part 3 can also be fixedly connected to the protective cover part 1, thereby effectively fixing the relative position of the sensor part 3 and protecting the body of the sensor part 3.

[0037] It is understood that, in the above-described connection structure, those skilled in the art can fix the sensor unit 3 to the protective cover unit 1 using four M6 bolts, and can also fix the sensor unit 3 to the mounting unit 2 using two M16 bolts. During installation of the mounting unit 2, it can be connected to the drilling tool using bolts or by welding.

[0038] Through the above-described connection structure, the sensor unit 3, the mounting unit 2, and the protective cover unit 1 can form a whole, improving the stability during operation. It is worth noting that, in this embodiment, those skilled in the art have designed the protective cover unit 1 and the mounting unit 2 to be made of high-strength alloy steel or stainless steel, so that the hardness of the protective cover unit 1 and the mounting unit 2 can reach 30HRC or higher, thereby preventing impact wear on the sensor unit 3 from sand, ore, etc.

[0039] In the configuration of sensor unit 3, according to Figures 10 to 12 Those skilled in the art can configure the sensor unit 3 to include a housing unit 31 and a measurement module. Further, the measurement module includes a first measurement unit 33 and a second measurement unit 32.

[0040] Structurally, please refer to Figure 10 The second measuring part 32 and the first measuring part 33 are fixedly connected to the inner wall of the housing part 31. The housing part 31 is fixedly connected to the mounting part 2 and the protective cover part 1, thereby forming a structure in which the inside and outside of the sensor part 3 are stably connected.

[0041] Specifically, the second measuring part 32 can be fixedly connected to the housing part by spacer pins and double-sided adhesive, thereby completing the connection between the second measuring part 32 and the housing part 31.

[0042] With the above structure, those skilled in the art can use the second measuring unit 32 and the first measuring unit 33 to measure, store and transmit the X-axis inclination angle, Y-axis inclination angle and Z-axis rotation angle of the drill bit during operation, as well as to measure, store and transmit the pressure.

[0043] It is understood that those skilled in the art would set up a protective cover 1 to protect the sensor part 3, and the sensor part 3 has a housing part 31 to protect the second measuring part 32 and the first measuring part 33, thereby avoiding the second measuring part 32 and the first measuring part 33 from being subjected to large impacts during operation and avoiding the overall corrosion of the sensor part 3 and water ingress.

[0044] In the above structure, those skilled in the art can set up a first measuring unit to detect, store, and wirelessly transmit external pressure. The following is a detailed description of one embodiment.

[0045] In this embodiment, please refer to Figure 13 Those skilled in the art can configure the first measuring part 33 to include a pressure sensor 331, a mounting base 332, a mounting end cap 333, an outer ring part 334, and a positive electrode part 335. In a specific connection, the mounting end cap 333 and / or the outer ring part 334 can be fixedly connected to the housing part 31.

[0046] Furthermore, the outer ring 334 is fitted onto the outer wall of the mounting end cover 333, the mounting base 332 is fixedly connected inside the mounting end cover 333, the pressure sensor 331 is fixedly installed inside the mounting base 332, and the positive electrode 335 is electrically connected to the side of the pressure sensor 331 away from the mounting end cover 333.

[0047] With the above structure, the mounting base 332 is fixedly connected to the mounting end cover 333, and the pressure sensor 331 is connected inside the mounting base 332, thereby forming a relative structure in which the pressure sensor 331 is stably installed.

[0048] In the above structure, those skilled in the art can install the pressure sensor 331 inside the mounting end cover 333 via the mounting base 332, and fit an outer ring portion 334 on the outer wall of the mounting end cover 333, thereby forming a stable structure with good sealing performance inside and outside the mounting end cover 333.

[0049] Furthermore, according to Figure 14 Those skilled in the art can arrange the positive electrode portion 335 to pass through the middle position of the mounting base 332, so that one side of the mounting base 332 can be covered and closed.

[0050] It can be understood that the pressure sensor 331 or the power supply device of the pressure sensor 331 can be charged through the positive terminal 335.

[0051] In summary, those skilled in the art can configure the first measuring unit 33 to include a pressure sensor 331, a mounting base 332, a mounting end cap 333, an outer ring portion 334, and a positive electrode portion 335, so that the first measuring unit 33 can continuously detect and store the external pressure when the drill bit is working.

[0052] To overcome the shortcomings of existing technology where the pressure sensor 331 cannot perform wireless transmission or requires a wired connection, please refer to... Figure 15 In some embodiments, the mounting end cap 333 has a mounting groove 3331 on the side opposite to the mounting base 332. The mounting groove 3331 is used to mount the antenna, and the antenna is electrically connected to the pressure sensor 331.

[0053] Specifically, in this embodiment, please refer to Figure 16 Technicians in the field can install the pressure sensor 331 on one side of the mounting end cover 333, and open a mounting groove 3331 on the opposite side of the mounting end cover 333 to the pressure sensor 331, through which the antenna is installed.

[0054] It is understandable that in the above structure, the mounting groove 3331 on the mounting end cover 333 is recessed towards the pressure sensor 331, and the antenna installed in the mounting groove 3331 is electrically connected to the MCU. It is worth noting that the antenna in the mounting groove 3331 does not exceed the outer plane of the mounting groove 3331; that is, it does not form a protrusion on the side of the mounting end cover 333 opposite to the pressure sensor 331. This makes the structure of the first measuring unit 33 more stable, and the connection structure between the first measuring unit 33 and the outside world more reasonable and stable.

[0055] Based on the antenna structure described above, pressure data collected by pressure sensor 331 can be stored first, and then wirelessly transmitted via the antenna when statistical data is needed. Wireless transmission here includes Bluetooth transmission, etc.

[0056] In the process of measuring pressure, in some optional implementation methods, according to Figure 15 Those skilled in the art can configure a diaphragm 336 to be sleeved on the outer wall of the positive electrode portion 335, with the outer wall of the diaphragm 336 abutting against the inner wall of the outer ring portion 334.

[0057] Specifically, in this embodiment, a diaphragm 336 can be provided on the inner wall side of the outer ring portion 334 away from the pressure sensor 331. The diaphragm 336 is sleeved on the outer wall of the positive electrode portion 335, thereby forming a covering and blocking structure on the side of the outer ring portion 334 away from the pressure sensor 331, which can then seal the mounting end cap 333 and the cavity inside the outer ring portion 334.

[0058] It is understood that in this embodiment, the diaphragm 336 can be manufactured using an adhesive coating process. The portions of the outer ring 334 and the positive electrode 335 that contact the diaphragm are treated by shot blasting or sandblasting.

[0059] By employing the aforementioned structure and process, after shot blasting or sandblasting the portions of the outer ring 334 and the positive electrode 335 that contact the diaphragm, a microscopic shape can be formed on the contact portions, thereby increasing the surface area and roughness of the contact surfaces. This arrangement significantly improves the connection strength at the junctions of the diaphragm 336 with the positive electrode 335 and the outer ring 334.

[0060] In this embodiment, the diaphragm 336 is manufactured using an overmolding process. Before manufacturing, the contact areas need to be cleaned using solvent cleaning or plasma cleaning. This cleaning process improves the adhesion of the contact areas. After overmolding, heat curing is performed to enhance the bond strength. Furthermore, during use, the rubber-made diaphragm 336 exhibits a more stable structure, meaning it can quickly recover its deformation after being subjected to external forces.

[0061] Preferably, in a further configuration, the side of the diaphragm 336 facing the mounting base 332 forms a sealed cavity with the inner wall of the outer ring portion 334, and the sealed cavity is filled with silicone oil to form a silicone oil layer 337, which contacts the pressure sensor 331.

[0062] In this embodiment, those skilled in the art can arrange one side of the silicone oil layer 337 to contact the diaphragm 336, and the other side of the silicone oil layer 337 to contact the pressure sensor.

[0063] With the above structure, during the operation of the drilling tool, external cement, sand and gravel come into direct contact with the diaphragm 336, so that the pressure can be transmitted to the silicone oil layer 337 through the diaphragm 336, and then to the pressure sensor 331 through the silicone oil layer 337, so that the pressure sensor 331 can measure the external pressure.

[0064] Understandably, in the above process, the contact area between the external cement, sand and gravel and the diaphragm 336 is significantly larger than the area when it directly contacts the pressure sensor 31. This allows the diaphragm 336 to fully contact the external cement, sand and gravel and water mixture and transmit the pressure through the silicone oil layer 337, effectively preventing pressure loss during transmission.

[0065] By means of the structure described above and by referring to the measurement process described above, the pressure sensor 331 can accurately measure the pressure exerted by external substances such as cement, sand, gravel, and water mixtures.

[0066] It is worth noting that, in the above structure, combined with the other embodiments described above, the rubber diaphragm 336 has a softer hardness and higher strength, and can withstand the impact of substances such as cement, sand, gravel, and water mixtures.

[0067] In the above embodiments, those skilled in the art configure the antenna to be installed in the mounting groove 3331 on the mounting end cover 333. In this embodiment, those skilled in the art can configure the mounting end cover 333 to be made of plastic material, and the position of the mounting groove 3331 corresponds to the position of the diaphragm 336, thereby improving the penetration effect of the antenna when propagating Bluetooth signals and making the data transmission process more stable.

[0068] In the above embodiments, those skilled in the art can provide a second measuring unit 32, thereby enabling the measurement, storage, and transmission of the drill bit's X-axis tilt angle, Y-axis tilt angle, and Z-axis rotation angle through the second measuring unit 32.

[0069] For details, please refer to Figure 17 The second measuring unit 32 includes a battery unit 321, a battery management unit 322, and a battery status monitoring unit 323. The positive electrode unit 335 is electrically connected to the input terminal of the battery unit 321, the battery management unit 322 is electrically connected to the battery unit 321, and the battery status monitoring unit 323 is electrically connected to the battery unit 321. It is used to charge, monitor, and manage the battery unit 321.

[0070] In the above structure, those skilled in the art can set the battery unit 321 as a rechargeable lithium battery. The parameters of the rechargeable lithium battery can be 3.7V and 1850mAh. Then, the battery management unit 322 and the battery status monitoring unit 323 are electrically connected to the battery unit 321, so that the status of the battery unit 321 can be monitored and managed, thereby making the battery unit 321 more stable during the power supply process.

[0071] It is understood that in the above structure, the battery section 321 and the positive electrode section 335 can be electrically connected, so that the battery section 321 can be charged through the positive electrode section 335.

[0072] Preferably, the second measuring unit 32 further includes a pressure measuring module, which is electrically connected to the pressure sensor 331 and is used to receive and transmit the analog signal output by the pressure sensor. That is, in this embodiment, the pressure measuring module can be electrically connected to the pressure sensor 331, thereby amplifying and performing AD conversion on the signal output by the pressure sensor 331.

[0073] Understandably, a microcontroller is also provided in the second measuring unit 32, which can receive the pressure signal after it has been amplified and converted by the pressure measuring module.

[0074] More preferably, the second measuring unit 32 further includes an acceleration module for measuring the X-axis tilt angle, Y-axis tilt angle and Z-axis rotation angle of the drill bit.

[0075] In this embodiment, the X-axis tilt angle, Y-axis tilt angle, and Z-axis rotation angle data can be acquired via an accelerometer module. In a specific implementation, the accelerometer module and a velocity sensor can be electrically connected. The velocity sensor measures the X-axis tilt angle, Y-axis tilt angle, and Z-axis rotation angle, which are then collected by the accelerometer module.

[0076] Furthermore, in this embodiment, those skilled in the art can set the microcontroller model to MCU27, and the second measurement unit is also provided with a data storage module and a power line carrier module.

[0077] The data storage module can store pressure data, as well as X-axis tilt angle, Y-axis tilt angle, and Z-axis rotation angle data, and the power line carrier module can transmit digital signals during operation.

[0078] Furthermore, a clock module is also provided in the MCU27 and the power line carrier module, which can be used to synchronize the timing of the MCU27 and the power line carrier module and accurately track the time.

[0079] In the above embodiments, those skilled in the art would configure the sensor unit 3 to include a housing unit 31, and use the housing unit 31 to protect the second measuring unit 32 and the first measuring unit 33. In this embodiment, the housing unit 31 includes a rear cover 311, a retaining ring 312, and an outer shell 313. The rear cover 311 is fixedly connected to the outer shell 313, and the retaining ring 312 is sleeved on the outer wall of the second measuring unit 32.

[0080] The rear cover 311 is fixedly connected to the outer casing 313, thereby sealing and protecting the internal components of the sensor unit 3. In the connection structure, the rear cover 311 can be fixedly connected to the outer casing by bolts.

[0081] Furthermore, within the mounting space formed by the rear cover 311 and the outer shell 313, the retaining ring 312 is fitted onto the outer wall of the second measuring part 32, and the retaining ring 312 abuts against the inner wall of the outer shell 313, thereby fixing the relative position of the second measuring part 32.

[0082] Furthermore, those skilled in the art can configure the retaining ring 312 as a double-layered, earless retaining ring, which makes the positioning of the retaining ring 312 more convenient and accurate, and allows it to withstand a larger load after installation.

[0083] It is understood that those skilled in the art can fix anti-fool screws on the side of the back cover 311 opposite to the outer casing 313, so that the back cover 311 can be accurately positioned during installation, and the sensor unit 3 can be accurately positioned during installation.

[0084] In this embodiment, those skilled in the art use tin bronze to make the outer shell 313, thereby giving the outer shell 313 good corrosion resistance. Furthermore, using leaded brass to make the back cover 311 not only gives the back cover good corrosion resistance, but also gives the back cover 311 a yield strength greater than 400 MPa, so that the back cover will not be compressed and deformed when working underwater at a depth of 100 meters or more.

[0085] In one implementation, the following steps can be performed to obtain a more accurate Z-axis speed when obtaining the Z-axis speed.

[0086] Specifically, under non-actual operating conditions, the offset changes of the X and Y axes at different Z-axis speeds are obtained. It's important to note that this offset change can be a constant or a value that exhibits a functional relationship with the Z-axis speeds. Then, the Z-axis speed and the X-axis and Y-axis tilt angles at that Z-axis speed are obtained under actual operating conditions. Finally, the accurate X-axis and Y-axis tilt angles are obtained by subtracting the X-axis offset change at the non-actual operating Z-axis speed from the X-axis tilt angle, and the Y-axis offset change at the non-actual operating Z-axis speed from the Y-axis tilt angle.

[0087] It is understandable that the aforementioned non-actual working state refers to the drill bit idling along the Z-axis without load, thus allowing for the measurement of offset changes in the X and Y axes. These offset changes are only related to the Z-axis rotation speed. In contrast, the actual working state refers to the drill bit operating within the actual wellbore. In this state, the X-axis and Y-axis inclination angles exhibit offset changes due to the influence of the Z-axis rotation speed.

[0088] In the above process, the Z-axis rotation speed of the drill bit can be divided into 5 to 10 segments within the range of -30 RPM to +30 RPM for measurement to obtain the amount of offset change. Example 2:

[0089] In this embodiment, the remaining structures are the same as those in Embodiment 1. In this embodiment, according to... Figure 15 The pressure sensor 331 is fitted with a first sealing ring 4 on its outer wall, and the first sealing ring 4 abuts against the inner wall of the mounting base 332.

[0090] In this embodiment, by setting the first sealing ring 4, the mounting base 332 and the pressure sensor 331 can be sealed, thereby improving the stability of the installation of the pressure sensor 331 and its sealing performance with the working environment.

[0091] Preferably, a second sealing ring 5 is fitted onto the outer wall of the mounting base 332, and the second sealing ring 5 abuts against the mounting end cover 333. That is, according to Figure 15 A second sealing ring 5 is provided between the mounting base 332 and the mounting end cover 333 to seal and fix the connection of the outer wall of the mounting base 332, thereby significantly improving the sealing performance of the installation environment of the pressure sensor 331.

[0092] More preferably, a third sealing ring 6 is fitted onto the outer wall of the mounting end cap 333, and the third sealing ring 6 abuts against the inner wall of the outer ring portion 334. According to... Figure 15 In the embodiment of Example 1, the diaphragm 336 abuts against the inner wall of the outer ring portion 334. In the embodiment of this example, the third sealing ring 6 abuts against both the inner wall of the outer ring portion 334 and the mounting end cap 333.

[0093] The above structure can significantly improve the sealing performance of the sealed cavity formed by the outer ring 334, the mounting end cap 333, and the diaphragm 336.

[0094] It is understood that in this embodiment, the sealing cavity can be further improved by the second sealing ring 5 and the third sealing ring 6, so that the silicone oil layer in the sealing cavity can avoid oil leakage or uneven pressure transmission.

[0095] In this embodiment, those skilled in the art can further modify the sealing structure of the housing 31 in the sensor section 3. Please refer to [reference needed]. Figure 13 The outer wall of the rear cover 311 is fitted with a fourth sealing ring 7, which abuts against the inner wall of the outer shell 313.
