Description

Technical Field

[0001] This utility model belongs to the field of geophysical technology, and specifically discloses a rainproof device for geophysical exploration systems. Background Technology

[0002] Resistivity measurement is a geophysical exploration method that boasts advantages such as high efficiency, high accuracy, simple data acquisition, and fast data processing. It has been widely applied in various exploration fields, including mineral exploration, engineering, and hydrological surveying. Resistivity measurements require the laying of cables and electrodes in a specific configuration. Figure 1 The data is collected in the form shown, and then the entire system is controlled by the acquisition terminal to complete the data acquisition.

[0003] However, fieldwork is heavily influenced by weather. Rain can wet the connections between the switch and cables, as well as the electrodes and cables, potentially causing short circuits. During data acquisition, high voltages exceeding 500V are supplied to the ground via cables and electrodes. If water enters these locations, the cables could burn out instantly, resulting in significant economic losses; alternatively, system instability could lead to data inconsistencies that fail to accurately reflect the underground conditions. Therefore, resistivity-based geophysical exploration systems cannot conduct fieldwork during rainy weather, especially during periods of continuous rainfall. Summary of the Invention

Detailed Implementation

[0043] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0044] This invention provides a rainproof device for geophysical exploration systems, which can improve the safety and environmental adaptability of geophysical exploration systems. The structure of the geophysical exploration system is as follows: Figure 1 As shown. Figure 2 This is an enlarged view of the acquisition component 1 in the geophysical exploration system, which includes the electrode 11 and the first latch 12. Figure 3 An enlarged view of the cable 2 connected to the acquisition unit 1 is shown, which includes a second buckle 21. The first buckle 12 matches the second buckle 21 to realize the connection between the electrode 11 and the cable 2.

[0045] In this embodiment, to protect the connection between electrode 11 and cable 2 (i.e., the connection between the first clip 12 and the second clip 21), a first rainproof module 5 is provided and fitted onto the connection between electrode 11 and cable 2. Figure 4 and Figure 5 As shown. The first rainproof module 5 includes a first electrode box 51 and a second electrode box 52; the first electrode box 51 and the second electrode box 52 have the same shape and matching size, and the first electrode box 51 and the second electrode box 52 are connected by a first rotating shaft 53. Both the first electrode box 51 and the second electrode box 52 include a main box and an extension box; the main box and the extension box are connected, and both ends of the main box have a first cable outlet. Taking the first electrode box 51 as an example, it includes a first main box 501 and a first extension box 502; the first main box 501 and the first extension box 502 are connected, and both ends of the first main box 501 have a first cable outlet 503.

[0046] In this embodiment, electrode 11 can be a copper electrode. Cable 2, connected to the copper electrode, is housed within the main housing 501, with both ends of cable 2 extending through the first outlet 503 on the corresponding side; the copper electrode extends through the extension housing 502. This structure effectively protects the connection between electrode 11 and cable 2.

[0047] To improve the ease and efficiency of installation of the first rainproof module 5, this embodiment further includes a first fastening member and a second fastening member that matches the first fastening member. The first fastening member is located at the edge of the first main box 501 of the first electrode box 51; the second fastening member is located at the edge of the main box of the second electrode box 52. For example, the first fastening member is a protrusion; the second fastening member is a groove that matches the protrusion. This embodiment uses a first rotating shaft 53 to connect the first electrode box 51 and the second electrode box 52, allowing them to rotate relative to each other. This facilitates installation at the connection point between the electrode 11 and the cable 2. Simultaneously, the first and second fastening members ensure stable fixation of the first and second electrode boxes 51 and 52, preventing them from opening during use and allowing rainwater to enter.

[0048] To prevent water leakage at the connection between the first extension box 502 and the first main box 501, this embodiment sets the first extension box 502 and the first main box 501 to be integrally connected. This integral connection structure also facilitates production and reduces installation steps. Similarly, the main box and extension box of the second electrode box 52 are also integrally connected.

[0049] To prevent rainwater from entering the first rainproof module 5 through the first outlet 503, both the first electrode box 51 and the second electrode box 52 in this embodiment include a first half-hole water-stop ring; the first half-hole water-stop ring is disposed on the first outlet 503, and the first half-hole water-stop ring is used to achieve sealing at the first outlet 503.

[0050] To prevent rainwater from entering the first rainproof module 5 through the port 504 of the first extension box 502, a second half-hole water-stop ring is provided at the port 504 of the first extension box 502 in this embodiment, thereby achieving a seal at the port 504 of the first extension box 502 using the second half-hole water-stop ring.

[0051] To enhance the shock absorption function of the first rainproof module 5, both the main box and the extension box in this embodiment have hollow walls, and a first buffer grid 54 is installed inside the hollow structure. The first buffer grid 54 can significantly reduce the impact of vibration on the connection between the electrode 11 and the cable 2.

[0052] Considering the requirements for field use—waterproof, lightweight, wear-resistant, and heat-resistant—the first electrode box 51, the second electrode box 52, and the first buffer grid 54 in this embodiment are all made of polypropylene (PP) synthetic resin. Polypropylene (PP) synthetic resin has advantages such as low price, wear resistance, heat resistance, lightweight, and waterproofness, and can be widely used in field applications, solving the problem that geophysical exploration systems cannot work in rainy weather.

[0053] The installation method of the first rainproof module 5 mentioned above is as follows:

[0054] 1. Connect the electrode 11 and the cable 2 through the first buckle 12 and the second buckle 21, wherein the copper sheet of the first buckle 12 and the copper sheet of the second buckle 21 should correspond in width respectively.

[0055] 2. Place the connected first buckle 12, second buckle 21 and cable 2 into the first electrode box 51. The cable 2 passes through the first outlet 503 with the first half-hole water-stop ring on the corresponding side, and the electrode 11 connecting wire passes through the port of the first extension box 502 with the second half-hole water-stop ring.

[0056] 3. Rotate the second electrode box 52 along the first rotating shaft 53 so that the first electrode box 51 and the second electrode box 52 are merged and the first fastening member and the second fastening member are fastened together.

[0057] 4. Vertically drive electrode 11 into the surface soil, ensuring its stability. Electrode 11 will then supply high-voltage current to the ground and collect signals such as potential and current. The first rainproof module 5, after installation, will be in the following state: Figure 6 As shown.

[0058] 5. Place the first rainproof module 5 flat on the ground with the second electrode box 52 facing upwards.

[0059] By utilizing the first rainproof module 5, the first buckle 12 and the second buckle 21 at the connection between the electrode 11 and the cable 2 are both in a sealed space. When it rains, the rainwater will flow away along the outer wall of the first rainproof module 5.

[0060] The structure of the changeover switch 3 in the geophysical exploration system of this embodiment is as follows: Figure 7 and Figure 8 As shown. The changeover switch 3 is an important component connecting two adjacent cables 2. By connecting the cables 2 to both ends of the changeover switch 3, the entire geophysical exploration system can be connected. At the same time, the changeover switch 3 is connected to the acquisition terminal 4 to realize the real-time transmission and display of the acquired data.

[0061] In this embodiment, to protect the connection between the changeover switch 3 and the cable 2, a second rainproof module 6 is provided, which is sleeved on the outside of the changeover switch 3; the structure of the second rainproof module 6 is as follows. Figures 9 to 11As shown. The second rainproof module 6 includes a first switch box 61 and a second switch box 62; both ends of the first switch box 61 and the second switch box 62 are provided with second cable outlets 601 for the cable 2 connected to the changeover switch 3 to extend out of the second rainproof module 6; one side of the first switch box 61 and one side of the second switch box 62 are connected by a second pivot 63; the other side of the first switch box 61 and the other side of the second switch box 62 are connected by a snap-fit. Exemplarily, the edge of the first switch box 61 is provided with a protrusion; the edge of the second switch box 62 is provided with a groove that matches the protrusion, and the protrusion and groove are used to achieve the snap-fit ​​connection between the first switch box 61 and the second switch box 62. In this embodiment, the second rainproof module 6 with the second pivot 63 can achieve the rotation of the first switch box 61 and the second switch box 62 while ensuring that their relative positions are fixed, which is convenient for installation; in this embodiment, the snap-fit ​​connection of the first switch box 61 and the second switch box 62 ensures the stability of the connection.

[0062] In this embodiment, the walls of the first switch box 61 and the second switch box 62 of the second rainproof module 6 are both hollow structures, and a second buffer grille 64 is provided inside the hollow structure. The second buffer grille 64 can play a shock-absorbing role, reducing the impact of vibration on the changeover switch 3 and the cable 2 connected to it.

[0063] To prevent rainwater from entering the second rainproof module 6 through the second outlet 601, the second rainproof module 6 in this embodiment also includes a third half-hole water-stop ring; the third half-hole water-stop ring is disposed on the second outlet 601.

[0064] Considering the requirements for field use, such as waterproof, lightweight, wear-resistant, and heat-resistant properties, the first switch box 61, the second switch box 62, and the second buffer grid 64 in this embodiment are all made of polypropylene (PP) synthetic resin.

[0065] The installation method for the second rainproof module 6 mentioned above is as follows:

[0066] 1. Tighten the screws to connect both ends of the changeover switch 3 to the cable 2.

[0067] 2. Place the changeover switch 3 with the connected cable 2 inside the first switch box 61, and let the cable 2 pass out from the second outlet 601 with the third half-hole water-stop ring on the corresponding side.

[0068] 3. Rotate the second switch box 62 along the second pivot 63 so that the first switch box 61 and the second switch box 62 are combined and fastened together using a snap fastener.

[0069] 4. Place the second rainproof module 6 flat on the ground, with the second switch box 62 facing upwards, as shown. Figure 12 As shown.

[0070] By using the second rainproof module 6, both the switch 3 and the cable 2 interface are enclosed in a sealed space. When it rains, the rainwater will flow away along the outer wall of the second rainproof module 6.

[0071] This utility model is a rainproof device for geophysical exploration systems. It can protect the connection between electrode 11 and cable 2, as well as the connection between changeover switch 3 and cable 2. It has a simple structure, is easy to operate, easy to produce, and has a low cost.
