Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, and in particular to a multi-component triaxial gradient difference natural electromagnetic pulse signal receiving device. Background Technology

[0002] Electromagnetic wave detection technology is a powerful tool in the exploration of natural resources and geological information. Among the many electromagnetic detection technologies, passive electromagnetic wave detection technology based on natural field sources is a simple and effective detection method. It receives and analyzes natural electromagnetic pulse signals through electromagnetic pulse detection instruments, enabling the exploration of natural resources and geological information at great depths and breadths. Compared with traditional exploration methods, it is low in cost and high in efficiency.

[0003] However, existing passive electromagnetic wave detection technology based on natural field sources requires not only carrying electromagnetic pulse detection instruments to detect natural electromagnetic pulse signals during exploration, but also carrying high-performance computers and preparing mobile power supply facilities to analyze the detected natural electromagnetic pulse signals on-site and convert them into intuitive visual information. The on-site wiring is complicated, and the requirements for computer performance and power supply are high, making it inconvenient to use in complex terrain.

[0004] Existing patent CN115755196A discloses a horizontal twelve-component natural electromagnetic pulse signal receiving device and storage medium. In the technical solution disclosed in existing patent CN115755196A, cloud computing technology is used to reduce the number and types of equipment, reduce equipment costs, simplify the data transfer process, and increase security. In the technical solution of existing patent CN115755196A, the twelve-component natural electromagnetic pulse receiving device is used by hoisting, which has sufficient breadth for data acquisition but insufficient accuracy, and can only quickly determine the signal direction.

[0005] Existing patent CN218332000U discloses a single-axis natural electromagnetic pulse signal receiving device with azimuth measurement. In the technical solution disclosed in CN218332000U, a real-time azimuth measurement device is used to achieve accurate detection and positioning of natural electromagnetic pulse signals in a single direction. However, it can only detect and locate natural electromagnetic pulse signals in a single direction at any given time, and this technical solution cannot change the detection direction at any time while detecting natural electromagnetic pulse signals.

[0006] Therefore, the existing patent CN115755196A is complicated to adjust and has low exploration accuracy when exploring from multiple directions at the same time. The existing patent CN218332000U can only detect and locate natural electromagnetic pulse signals in a single direction. The detection angle is limited and the detection direction cannot be changed at any time when detecting natural electromagnetic pulse signals. Summary of the Invention

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Figure 1 This is a data transmission schematic diagram of a multi-component triaxial gradient difference natural electromagnetic pulse signal receiving device provided in an embodiment of the present invention. The embodiment of the present invention provides a multi-component triaxial gradient difference natural electromagnetic pulse signal receiving device, comprising:

[0044] A signal acquisition module is used to acquire natural electromagnetic pulse signals. The signal acquisition module includes a multi-component triaxial gradient difference natural electromagnetic pulse signal receiving device and an acquisition carrier unit. The acquisition carrier unit carries the multi-component triaxial gradient difference natural electromagnetic pulse signal receiving device for movement.

[0045] The cloud processing module is used to process the natural electromagnetic pulse signal collected by the multi-component triaxial gradient difference natural electromagnetic pulse signal receiving device using cloud technology, and obtain visualization information.

[0046] A local display module is used to display the visualized information;

[0047] The local control module is used to control the acquisition carrier unit.

[0048] For example, such as Figure 1 , Figure 2 As shown, the signal acquisition module includes a multi-component triaxial gradient difference natural electromagnetic pulse signal receiving device and an acquisition carrier unit. The multi-component triaxial gradient difference natural electromagnetic pulse signal receiving device receives natural electromagnetic pulse signals. The acquisition carrier unit carries the multi-component triaxial gradient difference natural electromagnetic pulse signal receiving device and is equipped with a signal local transmission unit from the signal transmission module. This unit can position the multi-component triaxial gradient difference natural electromagnetic pulse signal receiving device at the optimal signal receiving location. The natural electromagnetic pulse signal is then transmitted to a signal cloud transmission unit via the signal local transmission unit, and finally to a cloud server via the signal cloud transmission unit. The cloud server analyzes the data and then visualizes the results into charts, numbers, and other intuitive visual information. This visualization is transmitted back to the signal cloud transmission unit in real time. Upon receiving the visualization, the signal cloud transmission unit displays it to the local display module. The local display module then presents the visualization to the exploration personnel through a screen or other device, helping them to explore for natural resources and geological information. The visualization can also help the exploration personnel correct the location of the natural electromagnetic pulse signal collection in real time. Finally, the local control module issues operation commands, which are transmitted to the acquisition carrier unit via the signal transmission module, controlling the acquisition carrier unit to reach the optimal detection position.

[0049] In one possible embodiment, the data collection carrier unit is a drone.

[0050] For example, the data collection carrier unit can be various unmanned aerial vehicles, such as fixed-wing drones, rotary-wing drones, unmanned all-terrain vehicles, unmanned boats, automatic rotating supports, and other unmanned transport equipment, and the local control module is the remote control device of the drone.

[0051] In one possible embodiment, the cloud processing module is a cloud server on the Internet, and the local display module is a computer.

[0052] For example, the cloud processing module is a network server set up using cloud computing technology. It can perform data analysis on the received natural electromagnetic pulse signals online and transmit the analyzed visualization information, such as charts and specific values, to the exploration site via the Internet. Then, it is visualized and displayed on a local display device. The whole process is carried out in real time. The local display module is a computer with display function and network connection. Because the data processing needs have been transferred to the cloud, it is only necessary to display the visualization information and issue operation commands to make the entire multi-component triaxial gradient difference natural electromagnetic pulse signal receiving device run smoothly.

[0053] In one possible embodiment, a fixed shaft disk 1 is provided, around which three natural electromagnetic pulse signal receiving boxes 2 are slidably arranged. The three natural electromagnetic pulse signal receiving boxes 2 are fixed to the fixed shaft disk 1 by fastening knobs 3 and upper shaft disk 13. Multiple directional receiving antennas 21 are provided inside the natural electromagnetic pulse signal receiving boxes 2. The ground inside the natural electromagnetic pulse signal receiving boxes 2 is provided with a sliding groove that penetrates the bottom surface. The multiple directional receiving antennas 21 are equidistantly arranged and can slide freely along the sliding groove inside the natural electromagnetic pulse signal receiving boxes 2. The multiple directional receiving antennas 21 are connected to a connector 4 through wires 22. The connector 4 is connected to the signal local transmission unit in the above-mentioned signal transmission module.

[0054] The fixed shaft disk 1 includes a lower shaft disk 11, a fixed shaft 12, an upper shaft disk 13, and a fastening knob 3. The bottom of the fixed shaft 12 is screwed to the center of the lower shaft disk 11, and the top of the fixed shaft 12 is provided with an internal thread. The center of the upper shaft disk 13 is provided with a through hole corresponding to the internal thread at the top of the fixed shaft 12. The fastening knob 3 passes through the through hole at the center of the upper shaft disk 13 and is screwed to the top of the fixed shaft 12.

[0055] The directional receiving antenna 21 is provided with a fixing bolt 212, which passes through the sliding groove inside the natural electromagnetic pulse signal receiving box 2 and is screwed to the fixing nut 211. The fixing nut 211 is provided with symmetrical finger handles. The directional receiving antenna 21 is connected to a wire 22, which passes through the opening on the natural electromagnetic pulse signal receiving box 2 and connects to the connector 4 through the arc-shaped through groove on the lower shaft plate 11.

[0056] The natural electromagnetic pulse signal receiving box 2 is provided with a box cover 23. Slider blocks are provided on both sides of the long axis of the box cover 23. The natural electromagnetic pulse signal receiving box 2 is provided with a sliding groove corresponding to the slider of the box cover 23. The box cover 23 slides freely on the natural electromagnetic pulse signal receiving box 2. A shaft seat 27 is fixedly provided on one side of the natural electromagnetic pulse signal receiving box 2 relative to the fixed shaft disk 1. A spring buckle 24 is rotatably connected to the shaft seat 27 through 25. A spring 26 is provided between the shaft seat 27 and the spring buckle 24.

[0057] The lower shaft disk 11 has a circular groove along its outer edge, and the upper shaft disk 13 has a groove of the same size corresponding to the groove of the lower shaft disk 11. The natural electromagnetic pulse signal receiving box 2 has symmetrical arc-shaped protrusions at one end of the wire 22, and the arc-shaped protrusions correspond to the grooves on the upper shaft disk 13 and the lower shaft disk 11. The outer surface of the lower shaft disk 11 is provided with a hook 14, which is movably connected to the above-mentioned acquisition carrier unit.

[0058] For example, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the multi-component triaxial gradient difference natural electromagnetic pulse signal receiving device is part of the signal acquisition module in the multi-component triaxial gradient difference natural electromagnetic pulse signal receiving device. The multi-component triaxial gradient difference natural electromagnetic pulse signal receiving device is hooked or inserted onto the UAV or support frame of the acquisition carrier unit via hooks 14 provided on the outer surface of the lower shaft disk 11. Its position is changed by detecting the movement of the acquisition carrier unit. Figure 10 , Figure 11 , Figure 12 , Figure 13 As shown, the multi-component triaxial gradient difference natural electromagnetic pulse signal receiving device mainly consists of a natural electromagnetic pulse signal receiving box 2 and a fixed shaft disk 1. The natural electromagnetic pulse signal receiving box 2 has three sections, which can slide freely along the outer wall of the fixed shaft disk 1 in its groove, and are locked in their orientation by the upper shaft disk 13 and the fastening knob 3. Multiple directional receiving antennas 21 are installed inside the natural electromagnetic pulse signal receiving box 2. These antennas all face the same direction and are equidistantly spaced at different distances according to actual exploration needs. By receiving the same natural electromagnetic pulse signal through these equidistantly spaced antennas, the difference between them is the gradient difference of the natural electromagnetic pulse signal. This gradient difference allows for easy analysis and determination of the distance from which the natural electromagnetic pulse signal is emitted, significantly improving the accuracy of receiving the signal. Figure 7 , Figure 8 , Figure 9 As shown, the natural electromagnetic pulse signal receiving box 2 is also equipped with a spring clip 24. With the help of the spring clip 24, the box cover 23 on the natural electromagnetic pulse signal receiving box 2 can be locked onto the natural electromagnetic pulse signal receiving box 2.

[0059] The directional receiving antennas 21 are all of the same model, each measuring 64mm in length, 36mm in height, and 34mm in width. Each of the wires 22 connecting to the directional receiving antenna 21 contains four cables: two power cables (positive and negative) and two signal transmission cables. All wires 22 are connected to the acquisition carrier unit and the local signal transmission unit via connectors. The acquisition carrier unit provides power, and the local signal transmission unit transmits the signal. The natural electromagnetic pulse signal receiving box 2 is made of insulating material.
