多通道地下水抽取管之連接裝置Connection device for multi-channel groundwater extraction pipe

本發明係有關一種多通道地下水抽取管之連接裝置，尤指一種兼具轉動單一結構即可鎖合兩物件動作簡易快速，可確保各通道對齊之多通道地下水抽取管之連接裝置。The invention relates to a connection device for multi-channel groundwater extraction pipes, especially a connection device for multi-channel groundwater extraction pipes that can lock two objects by rotating a single structure, which is simple and fast in action and can ensure the alignment of each channel.

傳統之地下水抽取技術，通常需要鑽取多個不同深度的深井，以進行不同深度之地下水取樣。舉例而言，若要在深度100公尺、150公尺及300公尺處分別取樣,則必須分別鑽三個孔，然後再分別裝入水管，進而個別抽出深度100公尺、150公尺及300公尺之三處地下水，進行後續之分析及研究。中華民國專利公開編號202117176「多階同心圓式井管裝置」則揭露了一種多階同心圓式之地下水抽取管裝置，假設中央為一個通道，外圍分隔成6個通道，則可以取樣7個不同深度之地下水，但是只需要鑽一孔。然而上述之地下水抽取管之深度可能深達數十公尺或數百公尺，而一般常見之管件之長度少於10公尺，所以管件之間必須要連接。然而，前述多階同心圓式井管裝置的內部設有多個間隔部，如何對準、相連接且各通道分別對應相連通，是一難題。再者，由於各通道係對應不同深度，彼此間不能混合，否則抽取之地下水就不準確。有鑑於此，必須研發出可解決上述習用缺點之技術。 Traditional groundwater extraction techniques usually require drilling multiple deep wells of different depths to sample groundwater 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, and then install them into water pipes, and then extract samples at depths of 100 meters, 150 meters and 300 meters respectively. Three groundwaters within 300 meters will be followed up for analysis and research. The Republic of China Patent Publication No. 202117176 "Multi-stage concentric well pipe device" discloses a multi-stage concentric pipe device for extracting groundwater. Assuming that the center is a channel and the periphery is divided into 6 channels, 7 different channels can be sampled. The depth of the groundwater, but only need to drill a hole. However, the depth of the above-mentioned groundwater extraction pipes may be as deep as tens of meters or hundreds of meters, 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 tubular device is provided with a plurality of spacers inside, how to align, connect and communicate with each other is a difficult problem. Furthermore, since the channels correspond to different depths, they cannot be mixed with each other, otherwise the extracted groundwater will be inaccurate. In view of this, must develop the technology that can solve above-mentioned conventional shortcoming.

Each of the two first tube parts 10 has an outer tube diameter D1. Also, referring to Fig. 5A and Fig. 5B, the connecting device of the multi-channel groundwater extraction pipe may further include: A different-diameter double-thread connecting ring portion 40 has an upper connecting hole seat 41 and a lower connecting hole seat 42 communicating with each other. The upper connecting hole seat 41 is corresponding to the first pipe portion 10 and has an upper connecting hole seat 41. 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 diameter D1 of the outer tube. The lower connection hole seat 42 has a lower connection internal thread portion 421 and a lower connection diameter D3, the thread directions of the lower connection internal thread portion 421 and the upper connection internal thread portion 411 are opposite to each other; the lower connection diameter D3 It is smaller than the upper connection diameter D2, so that the upper connection hole seat 41 and the lower connection hole seat 42 have different diameter structures. At least one second pipe portion 50 is provided corresponding to the lower connection hole seat 42, and has at least one second external thread portion 51 and a second pipe diameter D4, the second pipe diameter D4 is equal to the lower connection diameter D3. A second anti-leak pad part 60 is arranged between the first pipe part 10 and the connecting ring part 40 of the double-thread thread with different diameters. The second anti-leak pad part 60 is corresponding to the lower connection hole seat 42 and has A through hole 61 . Thereby, the upper connecting internal thread portion 411 is in contact with the corresponding first external thread portion 121 of the first pipe portion 10 , and the lower connecting internal thread portion 421 is in contact with the second pipe portion 50 The second external thread portion 51 . Then rotate the different-diameter double-thread connecting ring part 40, and screw through the first external thread part 121 and the second external thread part 51 (although they are not the same element, but the principle of threading can refer to the 3B and the 3rd 3C ) The first pipe part 10 and the second pipe part 50, and the second anti-leak pad part 60 is squeezed between them to achieve a watertight structure.

Then the double-thread connection ring part 40 with different diameters is rotated once, and the first pipe part 10 and the first pipe part 10 and the second pipe part 10 can be locked by screwing respectively through the upper connection internal thread part 411 and the lower connection internal thread part 421. The two pipe parts 50 and the second anti-leak pad part 60 are squeezed therebetween to achieve a watertight structure. The third key point of this case is that the two first pipe parts 10 are all provided with the positioning marks 122, that is, as long as the two positioning marks 122 are aligned (as shown in Fig. After being closed and locked, the plurality of passages M therebetween are connected to each other, which can avoid sampling errors caused by the inadvertent mixing of groundwater drawn from different passages (this is a known technology, so it will not be described in detail, and will be stated first). Advantage and effect of the present invention can be summarized as follows: [1] Turning a single structure can lock two objects quickly and easily. In this case, the thread directions of the two first internal thread parts of the double-thread connecting pipe part are opposite to each other. Using the principle of reverse threads, as long as the double-thread connecting pipe part (single structure) is rotated, the two threads can be quickly connected. The fast locking of the groundwater extraction pipe with multiple channels (that is, the two first pipe parts) can not only make the two adjacent pipes move relative to each other, but also prevent the pipes from rotating when moving (changing the corresponding relationship between the channels), and the overall The locking action is simple and fast. Therefore, the two objects can be locked by rotating a single structure, and the action is simple and fast. [2] Ensures lane alignment. Both of the two first pipe parts are provided with the positioning marks, as long as the two positioning marks are aligned, that is, after the two first pipe parts are screwed and locked, the plurality of passages between the two first pipe parts correspond to each other correctly, and the extraction can be avoided. The groundwater in different channels is inadvertently mixed, which leads to the problem of sampling errors (this is a known technology, so it will not be described in detail, and it will be stated first). Therefore, the alignment of the channels can be ensured. The above is only a detailed description of the present invention through preferred embodiments, and any simple modifications and changes made to the embodiments will not depart from the spirit and scope of the present invention.
