[0001] The invention relates to the technical field of probe pipe connection structures, and in particular to a connection device for a mine probe pipe component whose connection process will not affect internal electric wires. Background Art

[0002] Borehole measuring instruments are often used in the drilling process of underground coal mine gas extraction, water exploration and drainage, geological survey, etc. This type of borehole measuring instrument usually consists of two parts: a borehole host and an in-hole probe. During the borehole measuring process, the in-hole probe detects and collects signals in the hole, and the borehole host displays the signal data and converts it into the required geological data. Subsequent drilling or mining work is then carried out based on the obtained data. Therefore, the borehole measuring instrument plays a key role in the entire drilling process.

[0003] The in-hole probe is usually composed of two or more parts, and the parts need to be frequently disassembled. In the prior art, the two adjacent parts of the in-hole probe are connected by internal and external threads, and wires are passed through them. When disassembling and assembling, at least one of the two adjacent parts needs to be rotated to ensure smooth connection. This makes it easy for the wires to be entangled or even broken during the fastening process, affecting the normal use of the product. Summary of the invention

[0024] Figure 2 It is a cross-sectional view of the AA plane provided by an embodiment of the present invention.

[0025] In the figure: a first probe tube component 1, a connecting head 11, a positioning rod segment 111, a first positioning point 12, a rotating ring 2, a second probe tube component 3, a groove 31, a positioning groove segment 311, a second positioning point 32, a blocking member 4, a metal gasket 5, a sealing ring 6, and a countersunk hole 7. DETAILED DESCRIPTION

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0027] Example

[0028] See also Figure 1 , Figure 2 , is a connection device for a mining probe pipe component provided by an embodiment of the present invention, such as Figure 1 As shown, the device comprises a first probe tube component 1, a connector 11 is formed at one end of the first probe tube component 1, a rotating ring 2 which can rotate relative to the connector 11 is mounted on the connector 11, and a limit assembly for limiting the axial movement of the rotating ring is formed on the connector 11; an external thread section is formed on the outer side of the rotating ring; specifically, the limit assembly comprises two semi-annular blocking members 4, each of which is fixedly connected to the connector 11 by a fixing screw. A fixing groove along its circumference is formed on the connector 11, and a part of each of the two semi-annular blocking members 4 is embedded in the fixing groove, and the parts of the two semi-annular blocking members outside the fixing groove form a block to the rotating ring. A metal washer 5 is arranged between the rotating ring 2 and the two semi-annular blocking members 4. In order to prevent the rotating ring from detaching from the first probe tube component and causing the device to fail to work properly, two semi-rings and metal washers are arranged near the end of the rotating ring of the first probe tube component. The two half rings can wrap the shaft of the first probe part, and each half ring is fastened by a fixing screw (three screws are the best). The two half rings and the metal washer can limit the axial movement of the rotating ring relative to the first probe part; and a groove for embedding the half ring is processed in the first probe part, so that the axial force of the rotating ring acts on the first probe part instead of the screw.

[0029] The second probe tube component 3 has a groove 31 formed at one end thereof, and an internal thread segment matched with the external thread segment is formed inside the groove 31 .

[0030] The connector 11 is used to be inserted into the groove 31, so that the first probe tube component 1 and the second probe tube component 3 are fixed and the rotating ring 2 is rotated to achieve the threaded connection between the first probe tube component 1 and the second probe tube component 3. Of course, it is conceivable that the first probe tube component provided in the present application may also need to be connected to a third probe tube component in addition to the second probe tube component, so a groove can be formed at one end of the first probe tube component away from the connector, so that the connection with the third probe tube component provided with a corresponding connector can be achieved.

[0031] Furthermore, in order to ensure that the first probe member 1 and the second probe member 3 do not rotate relative to each other after being connected, as shown in FIG. Figure 2 As shown, a positioning groove section 311 is formed on the inner side of the groove near its end, and the cross section of the positioning groove section 311 has a non-continuous circular structure in the circumferential direction; a positioning rod section 111 adapted to the positioning groove section is formed near the front end of the connector 11, and after the first probe tube component 1 and the second probe tube component 3 are connected, the positioning rod section 111 is inserted into the interior of the positioning groove section 311 to limit the relative rotation of the first probe tube component 1 and the second probe tube component 3. After the non-continuous circular positioning groove and the non-continuous circular positioning rod are connected, the two cannot rotate relative to each other, thereby ensuring that the first probe tube component and the second probe tube component will not rotate relative to each other after they are connected. Specifically, the non-continuous circular structure includes at least one straight line segment and at least one arc segment. Since the groove itself and the connector itself have a circular circumference, in order to facilitate processing and manufacturing, a part of the circular circumference of the groove can be processed into a straight line segment, which can ensure that there is no relative rotation and is simple to process and manufacture. The present application can preferably produce a "positioning flat square platform" structure including two straight segments at both ends and two arc segments, wherein the two straight segments and the two arc segments are arranged alternately. Since the positioning groove is located on the inner side of the groove, the user cannot directly observe and judge whether it is aligned when plugging with the positioning rod. In order to solve this problem, the present application embodiment can provide that the first probe tube component and the second probe tube component are respectively formed with a first positioning point and a second positioning point, and the first positioning point and the second positioning point are used to indicate and locate the plugging position of the positioning groove segment and the positioning rod segment in the axial direction.

[0032] Furthermore, at least one sealing ring 6 is formed on the connector 11, and the outer side of the sealing ring 6 is used to abut against the inner side of the groove 31 to form a sealing structure. A sealing ring is set at the end of the first probe tube component to seal the inside and outside of the tube. For easy operation, the rotating ring thread should contact the sealing ring first, which can be easily assembled. Two sealing rings can be set in actual use.

[0033] Furthermore, in order to ensure that the rotating ring can rotate under the drive of the wrench to ensure a tight connection, a clamping portion for connecting with a tightening wrench is formed on the outside of the rotating ring. Specifically, the clamping portion includes at least one countersunk hole 7 arranged at a certain interval along the circumference of the rotating ring 2, and at least one of the countersunk holes 7 is used to achieve the positioning and clamping of the hook wrench. The tightening of the rotating ring can be achieved by various existing methods. For this application, due to space limitations, the best tightening method is the hook wrench, and countersunk holes are processed on the outer ring of the rotating ring for positioning the hook wrench.

[0034] In summary, the connection device of the mining probe tube component provided by the present application has a simple and reasonable structure, is easy to install and use, has a wide range of applications, and has a tight connection. A rotating ring is added to the first probe tube component. The rotating ring can rotate relative to the first probe tube component, and an external thread that cooperates with the second probe tube component is provided at its end. During the tightening process of the first probe tube component and the second probe tube component, only the rotating ring rotates, and the first probe tube component and the second probe tube component do not rotate, so the wires in the probe tube are not affected. It is worthy of widespread promotion and use.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
