Description

Technical Field

[0001] This utility model belongs to the field of instrument wiring technology, specifically relating to a wiring device for geophysical instruments. Background Technology

[0002] In geological exploration operations, geophysical methods such as electrical and electromagnetic methods are widely used. These methods require the laying of a large number of cables and electrodes to form a data acquisition network. Therefore, field workers frequently perform cable splicing, branching, and connection to instrument terminals. These wiring operations are often located in field sites with complex terrain and humid and harsh environments, so the connections must be firm and reliable to ensure stable data transmission. Loosening of any connection point may lead to signal attenuation and increased noise, directly affecting the quality of exploration data and the accuracy of interpretation results.

[0003] In practical applications, cables exposed outside the junction box are easily pulled by people stepping on them, equipment scraping them, or by changes in terrain. This external tension is directly transmitted to the fragile electrical connection points inside the box. In addition, in scenarios with multiple cables connected, multiple cables in the narrow space of the box are not only prone to tangling and becoming messy, causing great inconvenience for installation and maintenance, but also different types of cables, when arranged in parallel at close range, will cause serious mutual interference due to electromagnetic induction. For example, the alternating magnetic field generated by high-current power lines will introduce induced electromotive force in adjacent signal lines, and the distributed capacitance between them will form signal crosstalk. These interferences will drown out the weak and effective signals collected by geophysical instruments, causing the data signal-to-noise ratio to drop sharply, ultimately affecting the accuracy of geological exploration results.

[0015] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0016] Example: Figure 1 As shown in Figure 5: A wiring device for a geophysical instrument includes an insulating box 1. An elevating frame 11 is installed inside the insulating box 1. Several mounting seats 12 are slidably connected to the top of the elevating frame 11. A terminal block 13 is installed on the top of the mounting seat 12. Several terminal lugs 14 are installed on the top of the terminal block 13. Two constraint base plates 15 are installed inside the insulating box 1. An insulating cover plate 2 is provided on the top of the insulating box 1. A shielding cover 3 is provided above the elevating frame 11. Several barrier plates 31 are slidably connected to both sides of the shielding cover 3. Two partition plates 4 are installed on the inner wall of the insulating box 1. Two compaction plates 41 are vertically slidably arranged inside the insulating box 1.

[0017] The insulating box 1, as the main load-bearing structure of the entire wiring device, provides a closed protective space for all internal electrical components, isolating them from dust, moisture, and impurities in the outdoor environment. An elevation frame 11 is installed inside the insulating box 1, which raises the subsequently installed wiring components to a certain height at the bottom of the insulating box 1, preventing water accumulation or damp ground from affecting electrical connections. Several mounting seats 12 are slidably connected to the top of the elevation frame 11. The mounting seats 12 can be flexibly adjusted in position on the elevation frame 11 via a sliding structure, adapting to different wiring layouts according to actual wiring needs in the field, such as differences in the number and length of cables, without requiring disassembly and reinstallation of the entire structure, thus improving wiring operations. For flexibility and convenience, the mounting base 12 has a terminal block 13 installed on its top. The terminal block 13, as the core wiring component, provides a centralized connection interface for multiple cables, enabling orderly splicing and branching. Several connector lugs 14 are installed on the top of the terminal block 13. The connector lugs 14 enhance the tightness of the connection between the cable and the terminal block 13, and the crimping method reduces the contact resistance of the cable joints. Two constraint base plates 15 are installed inside the insulating box 1. The constraint base plates 15 can initially position the connected cables, restricting their movement within the box and preventing multiple cables from tangling. An insulating cover plate 2 is installed on the top of the insulating box 1, forming a completely enclosed space with the insulating box 1. To further enhance dust and water resistance, a shielding cover 3 is installed above the raised frame 11. The shielding cover 3 covers the terminal block 13, reducing interference from the external environment to the core wiring area. Several baffle plates 31 are slidably connected to both sides of the shielding cover 3. When the worker completes the wiring and places the shielding cover 3 above the raised frame 11, the baffle plates 31 without cables underneath will contact the top of the raised frame 11 to isolate and protect the cable connections inside the shielding cover 3. Two partition plates 4 are installed on the inner wall of the insulating box 1. The partition plates 4 can further constrain and fix the cables inside the insulating box 1, standardizing cable arrangement and preventing cables from tangling. Furthermore, during actual wiring, workers can... According to the required number of cables to be connected to the terminal block 13, slide the adjacent mounting bases 12 to a suitable distance. After wiring, the operator can place the cables in the appropriate grooves inside the constraint base plate 15 and the partition plate 4 to maintain a suitable distance between adjacent cables and avoid mutual interference between adjacent cables. Two compaction plates 41 are vertically slidably installed inside the insulation box 1. The compaction plates 41 cooperate with the partition plate 4 to clamp and fix the cables. This allows the external tension to be distributed to the partition plate 4 and the compaction plate 41 when the cables are subjected to external tension, preventing the tension from being directly transmitted to the connection point between the terminal block 13 and the terminal lug 14, preventing loosening of the connection and ensuring the stability of the cable connection.

[0018] Two constraint base plates 15 are respectively set on both sides of the lifting frame 11, and two partition plates 4 are respectively set on the side of the two constraint base plates 15 that are far apart from each other. The constraint base plates 15 are symmetrically distributed on both sides of the lifting frame 11, which can constrain and position the connected cables. The left cable corresponds to the left constraint base plate 15, and the right cable corresponds to the right constraint base plate 15, which completely avoids the cross-entanglement of the cables on both sides, making the cable arrangement clearer and making it easier for staff to quickly identify the purpose of the cables. The two partition plates 4 are located outside the constraint base plates 15, which can constrain and fix the cables after they are constrained by the constraint base plates 15. And through the clamping and fixing of the pressing plate 41, the cables can be fixed between the partition plate 4 and the pressing plate 41, avoiding the impact of external tension on the cable connection.

[0019] The insulating box 1 has two openings 16 on its side wall. Rain covers 17 are installed on both sides of the insulating box 1, and the two rain covers 17 are located above the two openings 16 respectively. The openings 16 serve as dedicated channels for cables to enter and exit the insulating box 1, guiding the cables into the interior of the insulating box 1. The rain covers 17 are installed on both sides of the insulating box 1, and the two rain covers 17 are located above the two openings 16 respectively. The rain covers 17 adopt an inclined structure, which can effectively block rainwater during field operations and prevent rainwater from seeping into the interior of the insulating box 1 through the openings 16, thus avoiding electrical components from getting damp and short-circuiting.

[0020] The bottom of the insulating cover plate 2 is provided with a constraint top plate 21, which is perpendicular to the constraint bottom plate 15. When the insulating cover plate 2 is closed on the top of the insulating box 1, the constraint top plate 21 and the constraint bottom plate 15 below can form an upper and lower clamping structure, clamping and fixing the cable from the upper and lower sides, constraining and fixing the cable, preventing the cables from contacting and tangling with each other, and distributing the external pulling force on the cable to the constraint top plate 21 and the constraint bottom plate 15, preventing the pulling force from being directly transmitted to the connection point of the terminal block 13 and the terminal lug 14.

[0021] An alignment block 22 is installed at the bottom of the insulating cover plate 2. The alignment block 22 is slidably set on the top of the insulating box 1. The alignment block 22 can precisely cooperate with the preset sliding groove on the top of the insulating box 1 to provide guidance for the closing of the insulating cover plate 2. This avoids the insulating cover plate 2 from not sealing tightly with the insulating box 1 due to positional deviation when the operator closes the cover plate, or the constraint top plate 21 from not being precisely aligned with the constraint bottom plate 15.

[0022] A positioning block 32 is installed at the bottom of the shield 3. The positioning block 32 is slidably set on the top of the lifting frame 11. The positioning block 32 can be embedded in the sliding groove on the top of the lifting frame 11 to provide stable support and sliding guidance for the shield 3, ensuring that the shield 3 can be continuously positioned above the lifting frame 11, preventing the shield 3 from tilting or shifting, so that the shield 3 can continuously protect the inner cable connection through cooperation with the barrier plate 31.

[0023] Insulating pads 42 are installed on the inner walls of both the partition plate 4 and the compaction plate 41, and bolts 43 are screwed into the interior of both the partition plate 4 and the compaction plate 41. The insulating pads 42 are made of rubber and have good insulation properties. They can effectively isolate the current conduction between the partition plate 4, the compaction plate 41 and the cable, and prevent the partition plate 4 and the compaction plate 41 from becoming electrified due to damage to the cable insulation layer, thereby preventing short circuit accidents. At the same time, the surface of the insulating pad 42 has a certain friction, which can enhance the clamping force between the partition plate 4, the compaction plate 41 and the cable, improve the stability of the cable fixation, and prevent the cable from sliding between the partition plate 4 and the compaction plate 41. The bolts 43 are screwed into the interior of the partition plate 4 and the compaction plate 41. The bolts 43 can be rotated to adjust the distance between the partition plate 4 and the compaction plate 41. The operator can flexibly adjust the clamping force according to the diameter of the cable to ensure that the cable is firmly fixed and to prevent damage to the cable insulation layer due to excessive clamping force, thus protecting the cable.

[0024] The working principle of this utility model is as follows: First, the operator needs to open the insulating cover 2 and thread the cables required for field exploration through the openings 16 on both sides of the insulating box 1. Then, according to the type and quantity of cables, slide and adjust the position of the mounting base 12 on the top of the lifting frame 11 so that the terminal block 13 is in a suitable position for easy wiring. Next, connect the cable ends to the corresponding terminal lugs 14 on the top of the terminal block 13, ensuring a tight connection to reduce signal attenuation. After connection, insert the positioning block 32 at the bottom of the shielding cover 3 into the lifting frame. 11. At the top, cover the shield 3 over the terminal block 13. Then, place the cables in the grooves of the constraint base plate 15 and the partition plate 4 respectively. Then, by sliding the compaction plate 41, the partition plate 4 and the compaction plate 41 clamp the cables. The cables are then clamped and fixed by rotating the bolt 43. Then, cover the top of the insulation box 1 with the insulation cover 2. At this time, the constraint top plate 21 at the bottom of the insulation cover 2 and the constraint base plate 15 clamp the cables vertically and vertically, constraining the position of the cables and preventing the cables from getting tangled.
