Description

Technical Field

[0001] This utility model belongs to the field of drilling communication equipment, specifically a drilling rod assembly with integrated communication transmission. Background Technology

[0002] Air drilling is a new drilling technology that uses compressed air or a gas-liquid mixture containing compressed air as the flushing medium in the borehole, or uses compressed air as both the power source for rock-breaking equipment and the flushing medium. During construction, compressed air is introduced into the drill pipe, and when compressed and ejected from the drill bit, it expels cuttings upwards, improving drilling efficiency. The drill bit is typically equipped with various sensors to measure parameters such as depth, acceleration, and temperature for real-time monitoring of its status. To transmit signals upwards, communication cables are usually laid inside the drill pipe. After the drill pipes are locked together, the contacts at both ends of the communication cable make contact to transmit signals. However, due to the complex working environment of the drill pipe, with high rotational speeds and significant vibrations, and the high precision required for communication cable connections, even slight deviations can lead to signal transmission distortion, hindering real-time monitoring of the drill bit during drilling and requiring improvement. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a drilling pipe assembly with integrated communication transmission.

[0004] The present invention adopts the following technical solution:

The pipe body is hollow and has a receiving cavity. The central gas rod is coaxially disposed within the pipe body to transport gas. The male and female connectors are respectively disposed at both ends of the pipe body, and they cooperate to connect multiple pipe bodies. The electrical connection mechanism includes elastic contacts, a conductive ring, and a wire. The elastic contacts are disposed on the top surface of the pipe body. The conductive ring is coaxially disposed at the bottom of the pipe body, and the elastic contacts are eccentrically disposed, with the distance from the elastic contacts to the axis of the pipe body equal to the radius of the conductive ring. The wire is disposed within the pipe body and connects the elastic contacts and the conductive ring. The wireless data transmission module is disposed within the pipe body, connected to the wire, and powered by it, relaying signals between adjacent pipe bodies.

[0006] Preferably, there are two elastic contacts, two conductive rings, and two wires. The conductive rings are arranged coaxially on the same plane, and the two conductive rings have different diameters. The elastic contacts are symmetrically arranged on both sides of the top surface of the rod, respectively opposite to the two conductive rings. The wireless data transmission module is connected between the two wires.

[0007] Preferably, the bottom surface of the rod is formed with two circular grooves for accommodating the conductive rings, the two circular grooves corresponding one-to-one with the two conductive rings, and the depth of the circular grooves is greater than the width of the conductive rings.

[0008] Preferably, the elastic contact includes a clearance hole, a limiting frame, a metal slider, and a return spring. The clearance hole is formed through the top surface of the rod. The limiting frame is disposed in the receiving cavity and opposite to the clearance hole, and has a sliding groove formed inside with its top communicating with the clearance hole. The metal slider is movably disposed in the clearance hole. When two adjacent rods are in contact, the metal slider contacts the conductive ring and moves downward into the sliding groove. The wire extends upward from the bottom of the limiting frame into the sliding groove and can be connected to the metal slider in contact with the conductive ring. The return spring is disposed in the sliding groove and connected between the bottom of the sliding groove and the bottom surface of the metal slider.

[0009] Preferably, the diameter of the sliding groove is larger than the diameter of the relief hole, and the bottom of the metal slider extends outward to form a limiting block, the diameter of which is larger than the diameter of the relief hole and smaller than the diameter of the sliding groove.

[0010] Preferably, the length of the metal slider is greater than the distance from the top of the wire to the top of the clearance hole.

[0011] Preferably, a fixing rod is also formed inside the receiving cavity of the rod body. Several groups of fixing rods are evenly arranged along the extension direction of the central air rod. Each group of fixing rods is evenly distributed around the axis of the central air rod and connected between the central air rod and the rod body.

[0012] Preferably, a plurality of wireless data transmission modules are provided and located on the fixed rod. The arrangement of the wireless data transmission modules within the rod body is symmetrical about the center of the rod axis and symmetrical about the midpoint of the rod axis in the extension direction of the rod.

[0013] Preferably, the bottom of the central air rod is provided with an enlarged joint, the inner diameter of which is adapted to the outer diameter of the central air rod, and the two ends of two adjacent central air rods are interference-fitted through the enlarged joint.

[0014] Preferably, the outer surface of the male head is formed with an external thread, and the inner surface of the female head is formed with an internal thread that matches the external thread.

[0015] As can be seen from the above description of this utility model, compared with the prior art, the beneficial effects of this utility model are: compressed air is delivered through the central air rod, the central air delivery can better maintain the balance when the drill rod rotates, and signals are transmitted upward sequentially through the wireless data transmission module. The wireless data transmission module is powered through the electrical connection mechanism. The connection between two adjacent rods does not involve signal transmission. Compared with traditional communication cables, the wires only play the role of power supply. Therefore, the connection method adopted can better adapt to the complex use environment of the drill rod. As long as the power supply is unobstructed, the signal can be transmitted upward through the wireless signal transmission module, ensuring the accuracy of signal transmission and having high practicality.

[0016] Two flexible contacts, two conductive rings, and two wires are provided, which can form a circuit with the wireless data transmission module;

[0017] The metal slider is driven by a return spring to always move upward. When the two rods are connected, the conductive ring presses the metal slider downward to make it contact the wire and thus connect the circuit. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below through specific embodiments.

[0028] Reference Figures 1 to 8 As shown, a drilling rod assembly with integrated communication transmission includes a rod body 1, a central air rod 2, a male connector 3, a female connector 4, an electrical connection mechanism 5, and a wireless data transmission module 6.

[0029] The rod body 1 is hollow and has a receiving cavity.

[0030] The central air rod 2 is coaxially mounted within the rod body 1 to transport gas, and the central air supply maintains the balance during drill rod rotation. Specifically, a fixing rod 11 is formed within the receiving cavity of the rod body 1. Several sets of fixing rods 11 are evenly arranged along the extension direction of the central air rod 2. Each set of fixing rods 11 is evenly distributed around the axis of the central air rod 2 and connected between the central air rod 2 and the rod body 1, improving the stability of the central air rod 2 within the rod body 1 and ensuring the delivery of compressed gas. Furthermore, an enlarged connector 21 is provided at the bottom of the central air rod 2. The inner diameter of the enlarged connector 21 is adapted to the outer diameter of the central rod body 1. The ends of two adjacent central air rods 2 are interference-fitted through the enlarged connector 21 to ensure the airtightness of the connection between the two central air rods 2. The end face of the enlarged connector 21 should be chamfered to facilitate the insertion of the central air rod 2.

[0031] Male head 3 and female head 4 are respectively located at both ends of rod 1. Male head 3 has external threads formed on its outer surface, and female head 4 has internal threads formed on its inner surface that are compatible with the external threads. The two work together to connect multiple rods 1.

[0032] The electrical connection mechanism 5 includes an elastic contact 51, a conductive ring 52, and a wire 53. The elastic contact 51 is located on the top surface of the rod 1. The conductive ring 52 is coaxially arranged at the bottom of the rod 1, and the elastic contact 51 is eccentrically positioned with the distance from the elastic contact 51 to the axis of the rod 1 equal to the radius of the conductive ring 52. The wire 53 is located in the rod 1 and connects the elastic contact 51 and the conductive ring 52. Two elastic contacts 51, two conductive rings 52, and two wires 53 are provided, forming a circuit with the wireless data transmission module 6. The conductive rings 52 are coaxially arranged on the same plane, and the two conductive rings 52 have different diameters. The elastic contacts 51 are symmetrically arranged on both sides of the top surface of the rod 1, respectively opposite to the two conductive rings 52. The wireless data transmission module 6 is connected between the two wires 53. Specifically, the bottom surface of the rod 1 has two circular grooves 12 formed to accommodate the conductive rings 52. The two circular grooves 12 correspond one-to-one with the two conductive rings 52, and the depth of the circular grooves 12 is greater than the width of the conductive rings 52.

[0033] The elastic contact 51 includes a clearance hole 511, a limiting frame 512, a metal slider 513, and a return spring 514. The clearance hole 511 is formed through the top surface of the rod 1. The limiting frame 512 is disposed in the receiving cavity and is opposite to the clearance hole 511. The internal part has a sliding groove 515 whose top communicates with the clearance hole 511. The metal slider 513 is movably disposed in the clearance hole 511. When two adjacent rods 1 are in contact, the metal slider 513 contacts the conductive ring 52 and moves downward into the sliding groove 515. The wire 53 extends upward from the bottom of the limiting frame 512 into the sliding groove 515 and can be connected to the metal slider 513 in contact with the conductive ring 52. The return spring 514 is disposed in the sliding groove 515 and is connected between the bottom of the sliding groove 515 and the bottom surface of the metal slider 513. The return spring 514 drives the metal slider 513 to always move upward. When the two rods 1 are connected, the conductive ring 52 presses the metal slider 513 downward, causing it to contact the wire 53 and establish a circuit. The wire 53 is highly flexible, and its interference fit with the metal slider 513 improves the stability of the electrical connection. Specifically, the diameter of the sliding groove 515 is larger than the diameter of the clearance hole 511. The bottom of the metal slider 513 extends outward to form a limiting block 516. The diameter of the limiting block 516 is larger than the diameter of the clearance hole 511 but smaller than the diameter of the sliding groove 515, preventing the metal slider 513 from coming out of the clearance hole 511. The length of the metal slider 513 is greater than the distance from the top of the wire 53 to the top of the clearance hole 511, ensuring that the metal slider 513 is connected between the conductive ring 52 and the wire 53 to form a circuit.

[0034] The wireless data transmission module 6 is installed in the rod body and connected to and powered by the wire 53, relaying signals between adjacent rod bodies 1. Several wireless data transmission modules 6 are installed on the fixed rod 11. The arrangement of the wireless data transmission modules 6 is symmetrical along the axis of the rod body 1, and vertically symmetrical about the midpoint of the axis of the rod body 1 in the extension direction of the rod body 1, ensuring the balance of the rod body 1 and avoiding interference with the normal operation of the drill pipe. The wireless data transmission module 6 is a common device in the prior art that transmits data via wireless signals. Those skilled in the art can directly select it according to the conditions, and it is not the focus of this application; therefore, its structure will not be further described here.

[0035] When an additional drill rod is needed, the new drill rod is locked to the lower drill rod using the male connector 3 and female connector 4. At this time, the metal slider 513 moves downward under the pressure of the conductive ring 52 and its bottom connects to the wire 53. After the new drill rod is connected to the drilling rig, a new electrical circuit is formed. The wireless signal transmission module set in the rod body 1 can transmit various signals from the drill bit from bottom to top. This application realizes the delivery of compressed air through the central air rod 2. The central air supply can better maintain the balance when the drill rod rotates, and the wireless data transmission module 6 transmits signals upward sequentially. The wireless data transmission module 6 is powered by the electrical connection mechanism 5. The connection between two adjacent rod bodies 1 does not involve signal transmission. Compared with traditional communication cables, the wire 53 only serves to supply power. Therefore, the connection method adopted can better adapt to the complex use environment of the drill rod. As long as the power supply is unobstructed, the accuracy of signal transmission can be guaranteed, which has high practicality.

[0036] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model shall still fall within the scope of the patent of the present utility model.
