[0002] Drilling is a critical component of coal mining operations for gas extraction, groundwater exploration, and other related geological surveys. Especially when drilling long distances, the complexity and unpredictability of geological conditions often make it difficult to follow the planned trajectory. Accurate drilling trajectory data feedback is essential to ensure timely adjustments to the drilling route and progress, ensuring efficient and accurate construction. To achieve this, the role of the coal trajectory detector is crucial. Through a signal transmitter fixed inside a specialized drill pipe, it transmits real-time signals at the forefront of the drilling process, allowing for precise monitoring and control of the drilling trajectory.

[0003] However, the existing fixed carrier structure inside the steel pipe body is complex, which affects the overall water flow effect of the steel pipe body, causing blockage of the channel and damage to the rod body; the carrier structure is complex, affecting the overall water flow effect of the steel pipe body, and is difficult to disassemble, inefficient, time-consuming and labor-intensive; the carrier fixing effect is insufficient, resulting in poor signal transmission effect, affecting drilling efficiency.

[0007] Furthermore, the diameter of the tracker detector supporting device changes in a step-like manner along its axial direction; the outer wall of the large-diameter end of the tracker detector supporting device is detachably connected to the inner wall of the steel pipe body, and the outer wall of the small-diameter end does not contact the inner wall of the steel pipe body.

[0008] Furthermore, a rubber plug opening is reserved in the middle of the large diameter end of the tracker detector carrying device; and a plurality of water passages are distributed circumferentially along the rubber plug opening.

[0009] Furthermore, the plurality of water passages are distributed in an equidistant array along the circumference of the rubber stopper opening.

[0011] Furthermore, the outer wall of the large diameter end of the tracker detector carrying device has a second external thread, and the inner wall of the steel pipe body has a second internal thread; the second internal thread and the second external thread are fastened together to achieve a detachable connection.

[0012] Furthermore, the length of the water passage is equal to the length of the second external thread.

[0013] Furthermore, the length of the rubber stopper opening is equal to the length of the second external thread.

[0014] Furthermore, the outer wall of one end of the steel pipe body has a first external thread, and the inner wall of the other end has a first internal thread; the steel pipe body is provided with no less than two, which are connected end to end through the first external thread and the first internal thread.

[0030] See also Figure 1 The present invention discloses a drill pipe specifically designed for a coal tracker detector, comprising a steel pipe body 1; a tracker detector carrier 2 disposed within the steel pipe body 1; the tracker detector carrier 2 is a hollow structure, the outer wall of the tracker detector carrier 2 being detachably connected to the inner wall of the steel pipe body 1; and a plurality of water passages 8 are defined along the axial direction of the tracker detector carrier 2. By providing the water passages 8 in the tracker detector carrier 2, this embodiment solves the problem of blockage in the drill pipe channel carrying tracker detectors. Furthermore, the detachable connection between the tracker detector carrier 2 and the steel pipe body 1 simplifies the installation and removal process, improves work efficiency, and reduces maintenance costs.

[0031] In a feasible embodiment of the present invention, see Figure 3 The diameter of the tracker detector carrying device 2 changes in a step-like manner along its axial direction; the outer wall of the large-diameter end of the tracker detector carrying device 2 is detachably connected to the inner wall of the steel tube body 1, and the outer wall of the small-diameter end does not contact the inner wall of the steel tube body 1.

[0032] In a feasible embodiment of the present invention, see Figure 2 A rubber plug opening 7 is reserved in the middle of the large-diameter end of the tracker detector carrier 2; several water passages 8 are distributed circumferentially along the rubber plug opening 7. The diameter of the rubber plug opening 7 is larger than the diameter of the hollow structure within the tracker detector carrier 2. In this embodiment, the tracker detector carrier 2 has a cylindrical hollow structure. The detector is loaded inside and blocked with a rubber plug to prevent water ingress. The external structure does not affect the water flow through the drill pipe, effectively waterproofing the entire structure and preventing water damage to the signal transmitter.

The length of the rubber stopper 7 and the water passage 8 is equal to the length of the second external thread 6. After the second internal thread 5 of the steel pipe body 1 and the second external thread 6 of the tracker detector carrier 2 of this embodiment are tightened, a gap is left between the hollow structure and the inner wall of the steel pipe body 1 for water to pass through. The second internal thread 5 and the second external thread 6 are tightly connected and the structure is simple, which not only facilitates the disassembly operation but also prevents the carrier device from shaking during drilling construction. The reserved water passage 8 has a good water-passing effect, prevents impurities brought by the water from causing blockage of the channel, improves the overall service life of the drill pipe, increases the drilling construction efficiency, and reduces cost expenditure.

[0034] In a feasible embodiment of the present invention, the outer wall of one end of the steel tube body 1 has a first external thread 3, and the inner wall of the other end has a first internal thread 4; the steel tube body 1 is provided with at least two first external threads 3 and first internal threads 4 connected end to end. The first external threads 3 and first internal threads 4 are arranged with equal width along the length direction of the steel tube body 1.

[0035] The working principle of this utility model is as follows:

[0036] The utility model discloses a special drill pipe structure comprising a steel pipe body 1 and a tracker detector carrier 2. The steel pipe body 1 has a first external thread 3 at one end and a first internal thread 4 at the other end. The internal thread of the steel pipe body 1 is connected to the tracker detector carrier 2. The large diameter end of the external thread of the tracker detector carrier 2 has a certain thickness and is provided with a water passage 8 and a rubber plug opening 7. The diameter decreases in a stepwise manner toward the other end, presenting a cylindrical hollow structure. The detector is loaded inside and plugged with a rubber plug to prevent water ingress. The external part does not affect the water flow of the entire drill pipe. The utility model can solve the problems of blockage in the tracker detector drill pipe channel and the problem of unstable tracker detector loading affecting signal transmission, thereby increasing the service life of the coal tracker detector drill pipe and reducing costs.
