Description

Technical Field

[0001] The utility model relates to the technical field of cable splitting technology for wide - area electromagnetic method in geophysical exploration, and particularly relates to a cable splitter box for geophysical exploration which is convenient for wiring. Background Technique

[0002] Geophysical exploration refers to detecting underground formation lithology, geological structure, etc. by studying and observing the changes of various geophysical fields, providing necessary data and information support for deep water and ore prospecting. During the process of geophysical wide - area electromagnetic method exploration, it is divided into a power supply end and a receiving end. Usually, the power supply end needs to increase the supply current to increase the magnitude of the transmitting power, so that the receiving end can receive stronger electrical signals to meet the requirements of exploration purposes. Since the current capacity of a single cable at the transmitting end is fixed, it is necessary to increase the number of cables to increase the total amount of transmitted current. Therefore, the main cable needs to be divided into multiple branch cables for simultaneously connecting multiple cable lines or sensors to meet different exploration needs.

[0003] In the prior art, usually, after peeling off the insulation layers of the main cable and the branch cables, the assembly of the joints is carried out, and the joints are wrapped with insulating tape or other insulating materials. However, there will be problems such as poor contact or excessive resistance at the joints wrapped with tape, which affects the stable transmission of current and even causes faults such as overheating and burning. Moreover, geophysical wide - area electromagnetic method exploration needs to be carried out outdoors, and there is a risk of water ingress at the joints in rainy days, thus causing potential safety hazards.

Preferably, the number of the first branch cable connectors 7 on the first sealing cover 3 and the first branch cable connectors 7 on the second sealing cover 4 is six each, and the number of the second branch cable connectors 8 is thirty-two. Therefore, the second box body 2 is one-in and six-out, and the first box body 1 is six-in and thirty-two-out for cooperating with the second box body 2.

[0038] When performing cable branching, insert one end of the main cable into the main cable connector 6, then enter the second box body 2 through the fixed pipe 5.

Then connect and fix the main cable to the second terminal block 10, and then connect the second terminal block 10 and the first branch cable connector 7 on the second sealing cover 4 through a wire. Thus, the pre-installation of the second box body 2 is completed;

[0039] After connecting the first branch cable connector 7 on the first sealing cover 3 and the first terminal block 9 through a wire, then connect all the second branch cable connectors 8 and the interfaces on the first terminal block 9 one by one through wires. Thus, the pre-installation of the first box body 1 is completed; finally, insert the external device wire with a plug into the second branch cable connector 8 to complete the main cable branching work.

[0040] This device can divide the main cable into multiple branch cables by utilizing the mutual cooperation of the first box body 1, the second box body 2, and the second branch cable connectors 8, avoiding the potential safety hazards of poor contact at the connection points and water ingress caused by the traditional wire splitting method, and improving the safety of the device.

[0041] Embodiment 2:

[0043] The branch cable joint two 8 includes a fixing cylinder one 13 and a waterproof nut 14. The fixing cylinder one 13 is fixedly connected to the inner wall of the box body one 1, and the waterproof nut 14 is threadedly connected to the outer wall of the fixing cylinder one 13.

[0047] Embodiment 3:

[0048] An easy-to-wire cable splice box for geophysical exploration. In this embodiment, the following improvements are made on the basis of Embodiment 1, as Figures 5-7 shown:

[0049] The plug includes a waterproof plug 15 and an electrode post two 16. Electrode posts one 11 are fixedly arranged on the inner walls of the fixing cylinder one 13 and the fixing cylinder two 22. One end of the electrode post one 11 is threadedly connected with a fastening bolt 12. A plurality of radially arranged metal plates 18 are rotationally connected to the inner walls of the fixing cylinder one 13 and the fixing cylinder two 22 through a rotating shaft one 17.

[0050] Torsion springs two are fixedly connected to the inner walls of the fixing cylinder one 13 and the fixing cylinder two 22, and the other ends of the torsion springs two are fixedly connected to the rotating shaft one 17. The waterproof plug 15 is inserted and matched with the inner walls of the fixing cylinder one 13 and the protection cylinder 21.

[0051] Insert the second electrode post 16 into the first fixing cylinder 13 and the protective cylinder 21, and pass through from the top of multiple metal plates 18. The bottom of the metal plates 18 shrinks, so that the top and bottom of the metal plates 18 are in contact with the second electrode post 16 and the first electrode post 11 respectively. At this time, both the first branch cable connector 7 and the second branch cable connector 8 are in the energized state; when the second electrode post 16 is detached from the first fixing cylinder 13 and the second fixing cylinder 22, the metal plates 18 are reset under the drive of the second torsion spring, so that the metal plates 18 are no longer in contact with the first electrode post 11. At this time, both the first branch cable connector 7 and the second branch cable connector 8 are in the de-energized state.

[0052] By setting the first rotating shaft 17 and the metal plates 18, when no plug is inserted into the first fixing cylinder 13 and the first branch cable connector 7, the metal plates 18 are not in contact with the first electrode post 11, so that the first branch cable connector 7 and the second branch cable connector 8 are in the de-energized state, avoiding the risk of electric shock caused by accidental contact of personnel and further improving the safety of the device.

[0053] Working principle: Before using this device, one end of the main cable needs to be inserted into the main cable connector 6 and the fixing pipe 5 in sequence and connected and fixed to the second terminal block 10. Then, the main cable connector 6 and the fixing pipe 5 are screwed together, and sealant is applied at the connection of the main cable connector 6 and the main cable. Then, the connections of the first group of the first branch cable connector 7 and the first terminal block 9, the second group of the first branch cable connector 7 and the second terminal block 10, and the second branch cable connector 8 and the first terminal block 9 are carried out. The three connection methods are the same. Wire noses are installed at one ends of the three groups of wires. Then, the fastening bolts 12 are rotated and removed from the first electrode post 11. Then, the wire noses are sleeved on the outer wall of the first electrode post 11, and then the fastening bolts 12 are screwed together with the first electrode post 11. The wire noses are fixed to the first electrode post 11 by using the fastening bolts 12. The other ends of the three groups of wires are fixedly connected to the first terminal block 9 and the second terminal block 10.

[0054] After all the wires are connected, cover the first sealing cover 3 and the second sealing cover 4. Then, according to the use needs, selectively connect the first branch cable connector 7 on the first sealing cover 3 and the first branch cable connector 7 on the second sealing cover 4 by using the cooperation of the plug and the connecting wire. Finally, install a plug on the wire of the external device and insert the plug into the first fixing cylinder 13 to complete the branching work of the main cable. The use of the plug can realize the quick connection between the device and the first box body 1 and improve the efficiency.

[0055] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto.
