The present invention relates to a connecting device for multi-channel underground water extraction pipes. In particular, it refers to a connecting device for multi-channel underground water extraction pipes that has a single rotating structure that can lock two objects easily and quickly, and can ensure the alignment of each channel.

Traditional groundwater extraction technology usually requires drilling multiple deep wells of different depths to conduct groundwater sampling at different depths. For example, if you want to take samples at depths of 100 meters, 150 meters and 300 meters, you must drill three holes respectively, then install water pipes respectively, and then draw out the samples at depths of 100 meters, 150 meters and 300 meters respectively.

However, the depth of the above-mentioned groundwater extraction pipes may be tens or hundreds of meters deep, and the length of common pipe fittings is less than 10 meters, so the pipe fittings must be connected. However, the aforementioned multi-stage concentric well pipe device is provided with multiple partitions inside. It is a difficult problem to align and connect each channel so that each channel can be connected correspondingly. Furthermore, since each channel system corresponds to different depths, they cannot mix with each other, otherwise the extracted groundwater will be inaccurate. In view of this, it is necessary to develop technology that can solve the above conventional shortcomings.

At least one first anti-leakage gasket part 30 corresponds to the two first pipe parts 10 and is coaxially disposed in the double-thread connecting pipe part 20. The first anti-leakage gasket part 30 corresponds to the two inner tubes 11 and the two inner tubes 11. The two outer tubes 12 and the plurality of partition walls 13 respectively have an inner ring 31, an outer ring 32 and a plurality of spacing ribs 33. Thereby, the two positioning marks 122 are aligned (as shown in Figure 3A, the first external thread portion 121 has a first length H1), so that the plurality of channels M of the two first tube portions 10 are aligned with each other. Correspondingly, the two first internal thread parts 21 contact the first external thread part 121 of the two first pipe parts 10 respectively, and then rotate the double thread connecting pipe part 20 to gradually screw together (such as 3B and 3B). As shown in Figure 3C, during the threading process, the two first external thread portions 121 first shorten from the first length H1 to a second length H2, and then shorten to a third length H3). The screw thread portion 121 makes the two first tube portions 10 gradually approach (as shown in Figure 4A) and finally come into contact, and the two inner tubes 11, the two outer tubes 12 and the plurality of partition walls 13 are squeezed accordingly. The inner ring 31 , the outer ring 32 and the plurality of spacing ribs 33 achieve a watertight connection between the two first tube parts 10 . Of course, in the aforementioned embodiments, the numbers of the first pipe part 10 , the double-thread connecting pipe part 20 and the first leak-proof gasket part 30 are respectively 2, 1, and 1 (the minimum number). instruction. In practice, this number can be flexibly increased, for example, modified to 6, 5, 5 or other quantities, and it still falls within the patent scope of this case. In practice, the first leak-proof gasket part 30 is fixed on one of the two first pipe parts 10, so that the inner ring 31, the outer ring 32 and the plurality of spacing ribs 33 are respectively fixed on the corresponding ones. The inner tube 11 , the outer tube 12 and the plurality of partition walls 13 . The aforementioned fixing type of the first anti-leak pad part 30 to one of the two first tube parts 10 may be at least one of an adhesive fixing structure and a fitting fixing structure. When it is an adhesive fixed structure, it can be fixed with waterproof glue (well-known technology, not shown in the drawings, and will be stated first). When it is a fitted fixed structure, the first anti-leakage pad part 30 also has an embedded groove 301, which is directly concavely formed on the inner ring 31, the outer ring 32 and the plurality of spacing ribs 33. (As shown in Figure 2), the inner ring 31, the outer ring 32 and the plurality of spacing ribs 33 are respectively fixed on the corresponding inner tube 11, the outer tube 12 and the plurality of partition walls 13. Each of the two first tube portions 10 has an outer tube diameter D1. Also, referring to Figures 5A and 5B, the connection device of the multi-channel groundwater extraction pipe may further include: A double-thread connecting ring portion 40 with different diameters has an upper connecting hole seat 41 and a lower connecting hole seat 42 that communicate with each other. The upper connecting hole seat 41 corresponds to the first pipe portion 10 and has an upper connecting inner socket. The thread portion 411 and an upper connection diameter D2, and the upper connection hole seat 41 is connected to the inner tube 11, and the upper connection diameter D2 is equal to the outer tube diameter D1. The lower connecting hole base 42 has a lower connecting internal thread portion 421 and a lower connecting diameter D3. The thread directions of the lower connecting internal thread portion 421 and the upper connecting internal thread portion 411 are opposite to each other; the lower connecting diameter D3 is smaller than the upper connection diameter D2, so that the upper connection hole seat 41 and the lower connection hole seat 42 have a different diameter structure. At least one second pipe part 50 is provided corresponding to the lower connection hole seat 42 and has at least a second external thread part 51 and a second pipe diameter D4, the second pipe diameter D4 is equal to the lower connection diameter D3. A second anti-leakage pad part 60 is provided between the first pipe part 10 and the different-diameter double-thread connecting ring part 40. The second anti-leakage pad part 60 corresponds to the lower connection hole seat 42 and has A through hole 61. Thereby, the upper connecting internal thread part 411 contacts the corresponding first external thread part 121 of the first pipe part 10 , and the lower connecting internal screw part 421 contacts the second pipe part 50 The second external thread portion 51 . Then, the double-thread connecting ring part 40 with different diameters is rotated, and the first external screw part 121 and the second external screw part 51 are screwed together (although they are not the same components, but the screwing principle can be referred to 3B and 3B). 3C) The first tube part 10 and the second tube part 50, and the second leak-proof gasket part 60 is squeezed therebetween to achieve a watertight structure. In addition, the connection device of the multi-channel groundwater extraction pipe may further include: The plurality of third anti-leakage pad portions 70 are used to be disposed between two related connection structures and components to improve the anti-leakage effect. A plurality of auxiliary tube parts 80. Each auxiliary tube part 80 of the plurality of auxiliary tube parts 80 has two auxiliary internal thread parts 81. The plurality of auxiliary tube parts 80 can be respectively disposed between two related connection structures and components, so as to Those who perform elastic adjustment of pipeline length. A pipe cover 90 (as shown in Figure 5A) is used to cover the connecting device provided in the multi-channel groundwater extraction pipe and corresponds to the uppermost first pipe part 10. The pipe cover 90 corresponds to the central channel 111 , and has at least one central tube hole 91, and corresponding to the plurality of channels M, has a plurality of channel tube holes 92. Thereby, the plurality of third anti-leak pad portions 70 can have different specifications, and can at least be sandwiched between: [a] As shown in Figure 1, between the first external thread portion 121 and the corresponding first internal thread portion 21. [b] Refer to Figure 5A, between the tube cover 90 and the first external thread portion 121. [c] Correspondingly between the first external thread portion 121 and the upper connecting inner thread portion 411. [d] Correspondingly, the lower connection is between the inner thread portion 421 and the second outer thread portion 51 . [e] Between the corresponding second external thread portion 51 and the auxiliary internal thread portion 81 . In addition, the diameter, material and related specifications of each of the aforementioned anti-leak pads (components or structures) may vary depending on the actual installation location, and do not depart from the scope of protection of this case. One of the key points of this case is to set up the double thread connecting pipe part 20. In this way, as long as the two first internal thread parts 21 are respectively contacted with the first external thread part 121 of the two first pipe parts 10, and then a single rotation of the double thread part 21 is required. The threaded connection tube part 20 can be screwed through the two first internal thread parts 21 to lock the two first tube parts 10 (as shown in Figure 4A), and the two inner tubes 11 and the two outer tubes The tube 12 and the plurality of partition walls 13 respectively squeeze the inner ring 31, the outer ring 32 and the plurality of spacing ribs 33 to achieve a watertight joint between the two first tube parts 10 (as shown in Figure 4B) . The second key point of this case is to set up the double-thread connecting ring portion 40 with different diameters. In the same principle, as long as the upper connecting inner thread portion 411 contacts the corresponding first outer thread portion 121 of the first pipe portion 10 , and the lower connecting inner thread portion 421 contacts the second outer thread portion 51 of the second tube portion 50 . Then, with a single rotation of the double-thread connecting ring portion 40 of different diameters, the upper connecting internal screw portion 411 and the lower connecting internal screw portion 421 can be screwed together to lock the first pipe portion 10 and the third pipe portion 10 respectively. The second tube portion 50 is squeezed between the second anti-leakage gasket portion 60 to achieve a watertight structure. The third key point of this case is that the two first pipe parts 10 are both provided with the positioning marks 122. That is, as long as the two positioning marks 122 are aligned (as shown in Figure 3A), the two first pipe parts 10 can be screwed in. After being closed and locked, the plurality of channels M are connected to each other, which can avoid inadvertent mixing of groundwater extracted from different channels and lead to sampling errors (this is a well-known technology, will not be described in detail, and will be stated first). The advantages and effects of the present invention can be summarized as follows: [1] Rotating a single structure can lock two objects quickly and easily. The thread directions of the two first internal thread parts of the double thread connecting pipe part in this case are opposite to each other. Using the reverse thread principle, the two thread connecting parts (single structure) can be quickly connected by rotating the double thread connecting pipe part (single structure). The groundwater extraction pipe with multiple channels (that is, the two first pipe parts) is quickly locked, which not only allows the two adjacent pipes to move relative to each other, but also does not rotate when the pipes move (changing the corresponding relationship between the channels). The overall The locking action is simple and fast. Therefore, the two objects can be locked together easily and quickly by rotating a single structure. [2] Ensures channel alignment. The two first pipe parts are both provided with the positioning mark. As long as the two positioning marks are aligned, even after the two first pipe parts are screwed and locked, the plurality of channels therebetween will correspond to each other correctly, thereby avoiding the possibility of extraction. Groundwater from different channels is accidentally mixed, resulting in sampling errors (this is a well-known technology, will not be described in detail, and will be stated first). Therefore, alignment of each channel can be ensured. The above is only a detailed description of the present invention through preferred embodiments. Any simple modifications and changes made to the embodiments do not deviate from the spirit and scope of the present invention.
