Abstract
Description
Technical Field
[0001] This invention relates to drilling equipment, specifically to a sliding intelligent inclinometer with a load-bearing, conductive, signal-transmitting, elongation-free, separable, and torsion-free cable. Background Technology
[0002] The sliding intelligent inclinometer features a load-bearing, conductive, and signal-transmitting cable with no elongation (patent number 201010217211.2). It is characterized by its small diameter, light weight, and high tensile strength. This cable can bear the weight of the probe and the frictional resistance of the pipe wall without elongation or deformation, simultaneously marking the probe's depth position, supplying power to the probe, and transmitting measurement signals. Conventionally, the cable and the inclinometer probe are connected as a single unit. During use, it was found that the method of connecting the cable and the inclinometer probe as a whole has functional shortcomings: (1) The sealing components at the connection between the cable and the probe are prone to aging and failure, which can lead to moisture entering the probe and causing measurement errors or damage to core components; (2) Damage to the cable sheath can cause moisture to seep into the probe along the cable core, and changes in ambient temperature and air pressure can cause condensation to form inside the measurement module, making it impossible to maintain a dry and constant working environment for the measurement module, and making it difficult to guarantee the accuracy and stability of the measurement data; (3) When the probe rotates for measurement, the cable is subjected to torsion, and the cumulative effect can cause the cable to twist and deform, affecting the cable length and the accuracy of probe depth positioning; (4) The irregular shape of the cable and probe connection makes the storage space much larger than the total volume of the individual components, which is inconvenient for storage and carrying. Summary of the Invention
[0003] Purpose of the invention: To address the above-mentioned shortcomings, this invention provides a sliding intelligent inclinometer with a load-bearing, conductive, and signal-transmitting cable that avoids torque on the cable when the probe rotates to measure the direction. The cable is non-elongating, separable, and non-twisting.
[0004] Technical Solution: To solve the above problems, the present invention employs a sliding intelligent inclinometer with a load-bearing, conductive, signal-transmitting, elongation-free, separable, and twist-free cable, including a probe connector connected to the inclinometer probe. The probe connector includes a first mating part connected to the inclinometer probe, a second mating part, and a second connecting part cable connected to the second mating part. The first mating part and the second mating part are axially positioned by a connector, and the first mating part and the second mating part can rotate freely relative to each other. The second mating part is used to transmit the power supplied by the second connecting part cable to the inclinometer probe, and is also used to receive the signal measured by the inclinometer probe transmitted by the first mating part. The first mating part is used to receive the power transmitted by the second mating part, and is also used to transmit the signal measured by the inclinometer probe.
[0005] Furthermore, it also includes a repeater connector disposed in the middle of the cable. The repeater connector includes a third mating part, a fourth mating part, and a fourth connecting part cable connected to the second connecting part cable of the probe connector. The third mating part and the fourth mating part are axially positioned by a connector and can rotate freely relative to each other. The fourth mating part is used to transmit the power supplied by the fourth connecting part cable and to receive the signal measured by the inclinometer probe transmitted by the third mating part. The third mating part is used to receive the power transmitted by the fourth mating part and to transmit the received signal measured by the inclinometer probe.
[0006] Furthermore, the first docking part includes a measurement and transmission module connected to the inclinometer probe, a first induction coil connected to the measurement and transmission module, and a first housing housing the first induction coil; the second docking part includes a power supply and data receiving module connected to the second connecting part by a cable, a second induction coil connected to the power supply and data receiving module, and a second housing housing the second induction coil; a connector connects the first housing and the second housing, and the first induction coil and the second induction coil transmit power and signals through electromagnetic conversion.
[0007] Furthermore, the third docking part includes a power receiving and data transmitting module cable-connected to the second connecting part, a third induction coil connected to the power receiving and data transmitting module, and a third housing housing the third induction coil; the fourth docking part includes a power supply and data receiving module cable-connected to the fourth connecting part, a fourth induction coil connected to the power supply and data receiving module, and a fourth housing housing the fourth induction coil; a connector connects the third housing and the fourth housing, and the third induction coil and the fourth induction coil achieve power and signal transmission through electromagnetic conversion.
[0008] Furthermore, the second outer shell includes a fixed part and a limiting part that are fixedly connected. Both the fixed part and the limiting part are cylindrical, and the bottom diameter of the limiting part is larger than the bottom diameter of the fixed part. The cross-section of the second outer shell is T-shaped. The connecting member is provided with a limiting cavity. The limiting part is located in the limiting cavity. The limiting cavity is used to limit the position of the limiting part, and the limiting part can rotate freely relative to the limiting cavity.
[0009] Furthermore, the connector is a cylindrical shell with openings at both ends. The limiting part is disposed inside the cylindrical shell. The fixing part is fixedly connected to the limiting part through one opening of the connector. The opening radius is smaller than the inner diameter of the cylindrical shell and smaller than the outer diameter of the limiting part. The first outer shell is disposed inside the cylindrical shell through the other opening of the connector and is fixedly connected to the connector.
[0010] Furthermore, the side of the limiting part and the end face of the end connected to the fixing part are provided with balls, and the limiting part contacts the inner wall of the connector through the balls.
[0011] Furthermore, the connector is provided with a positioning pin, and the connector is fixedly connected to the first housing through the positioning pin.
[0012] Furthermore, a fixed distance is maintained between the first outer shell and the second outer shell located within the cylindrical housing of the connector.
[0013] Beneficial Effects: Compared to existing technologies, the significant advantage of this invention is that the cable connecting the inclinometer probe can be freely twisted through the relatively freely rotating first and second mating parts, avoiding torque on the cable when the probe rotates to measure the direction, thus preventing it from affecting the cable's working length. By adding connector accessories to the existing load-bearing, conductive, and signal-transmitting cable of the sliding intelligent inclinometer, the cable's functionality is expanded. This allows the cable to twist freely at both ends of the connector while maintaining circuit continuity, ensuring the cable does not twist during probe rotation measurement. The cable itself and the cable and probe can be freely separated or connected through the connector, reducing the frequency of bending damage at the cable-probe connection point and facilitating the storage and portability of the sliding intelligent inclinometer system.

[0020] like Figure 1 As shown in the figure, the sliding intelligent inclinometer in this embodiment uses a load-bearing, conductive, signal-transmitting, elongation-free, detachable, and twist-free cable, including a repeater connector and a probe connector. Figure 2 As shown, the probe connector consists of three parts: probe end connection part 1, cable end connection part 2, and coupling part 3. Figure 3As shown, the probe end connection part 1 includes a first docking part 11 connected to the inclinometer probe. The first docking part 11 includes a measurement and transmission module 113 connected to the inclinometer probe, a first induction coil 112 connected to the measurement and transmission module 113, and a first housing 111 housing the first induction coil. The first housing 111 is made of stainless steel. The first docking part 11 is used to receive power transmitted from the second docking part 21 and to transmit the signal measured by the inclinometer probe. The signal measured by the inclinometer probe is electromagnetically converted through the first induction coil 112 and transmitted to the second induction coil 212, transmitting an oscillating magnetic field corresponding to the measurement signal.
[0021] like Figure 4 As shown, the cable end connection part 2 includes a second docking part 21 and a second connecting cable 22 connected to the second docking part 21. The second docking part 21 includes a power supply and data receiving module 214 connected to the second connecting cable 22, a second induction coil 212 connected to the power supply and data receiving module 214, and a second housing 211 accommodating the second induction coil 212. The second housing 211 is made of stainless steel and includes a fixing part 2112 and a limiting part 2111 that are fixedly connected. Both the fixing part 2112 and the limiting part 2111 are cylindrical, and the bottom diameter of the limiting part is greater than that of the cable end connection part. The bottom diameter of the fixing part is T-shaped, the side of the limiting part and the end face of the end connected to the fixing part are embedded with ball bearings 213. The limiting part makes point contact with the inner wall of the connector 31 through the ball bearings 213 to achieve relative rotation with the connector 31. The second docking part 21 is used to transmit the power supplied by the second connecting part cable 22 to the inclinometer probe, and to receive the signal measured by the inclinometer probe emitted by the first docking part 11. Power is input from the second connecting part cable 22, and electromagnetic conversion is achieved through the second induction coil 212 to supply the oscillating magnetic field corresponding to the power to the first induction coil 112.
[0022] like Figure 5As shown, the coupling part 3 includes a connector 31 and a positioning pin 32. The connector 31 connects the first outer shell 111 and the second outer shell 211. The first docking part 11 and the second docking part 21 are axially positioned by the connector 31, and the first docking part 11 and the second docking part 21 can rotate freely relative to each other. The connector 31 is a stainless steel U-shaped component, that is, the connector 31 is a cylindrical shell with openings at both ends. The cylindrical shell has a limiting cavity inside, and the limiting part is located in the limiting cavity. The limiting cavity is used to limit the position of the limiting part, and the limiting part can rotate freely relative to the limiting cavity. The fixing part is fixedly connected to the limiting part through the opening at one end of the connector 31. The opening radius is smaller than the inner diameter of the cylindrical shell, and the outer diameter of the limiting part is larger than the inner diameter of the opening. Therefore, the limiting part is stuck in the limiting cavity. The connector 31 positions the first docking part 11. The first outer shell 111 is set inside the cylindrical shell through the opening at the other end of the connector 31 and is fixedly connected to the connector 31 by the positioning pin. The connector 31 brings the first induction coil 112 in the first housing and the second induction coil 212 in the second housing closer together, enabling the transmission of power and signals between the first induction coil 112 and the second induction coil 212 through electromagnetic conversion. A fixed distance is maintained between the first outer shell 111 and the second outer shell 211 located inside the cylindrical housing of the connector 31.
[0023] like Figure 6 As shown, the repeater connector includes three parts: an upper connecting part 5, a lower connecting part 4, and a coupling part 3. The lower connecting part 4 includes a third mating part 41 connected to the second connecting part cable 22. The third mating part 41 includes a power receiving and data transmitting module connected to the second connecting part cable 22, a third induction coil 412 connected to the power receiving and data transmitting module, and a third housing 411 housing the third induction coil. The third housing 411 is made of stainless steel. The third mating part 41 is used to receive power transmitted from the fourth mating part 51 and to transmit sensor signals transmitted by the probe connector. The sensor signals are electromagnetically converted through the third induction coil 412, transmitting the corresponding oscillating magnetic field to the fourth induction coil 512.
[0024] The upper connecting part 5 includes a fourth docking part 51 and a fourth connecting part cable 52 connected to the fourth docking part 51. The fourth docking part 51 includes a power supply and data receiving module connected to the fourth connecting part cable 52, a fourth induction coil 512 connected to the power supply and data receiving module, and a fourth housing 511 housing the fourth induction coil 512. The fourth housing 511 is made of stainless steel and is configured the same as the second housing 211. The fourth housing and the third housing are also connected by a coupling 3 to achieve a non-contact rotatable connection. The fourth docking part 51 is used to transmit the power supplied by the fourth connecting part cable 52 to the third docking part 41 and to receive the sensor signal emitted by the third docking part 41. Power is input from the fourth connecting part cable 52, and electromagnetic conversion is achieved through the fourth induction coil 512 to supply the oscillating magnetic field corresponding to the power to the third induction coil 412.
[0025] The first and second induction coils each consist of two identical magnetic containers, a primary coil, and a secondary coil. One magnetic container is fixed to the inner wall of the first housing as a fixed magnetic container, inside which the primary coil is wound. This primary coil is connected to the signal receiving and power transmitting terminals of the measurement and transmission module. The other magnetic container is fixed inside the second housing as a moving magnetic container, inside which a secondary coil is wound. This secondary coil is connected to the signal transmitting and power receiving terminals of the power supply and data receiving module. The first and second induction coils simultaneously transmit the measurement data signal from the probe tilt sensor and the power required for its operation. The third and fourth induction coils adopt the same structure.
