Description

Technical Field

[0001] This utility model relates to the field of wide-area electromagnetic exploration technology, specifically a power supply protection device for wide-area electromagnetic exploration equipment. Background Technology

[0002] Electromagnetic exploration primarily utilizes differences in electromagnetic properties for exploration. This includes wide-area electromagnetic exploration equipment. When using such equipment, a power supply protection device is required to properly isolate the wiring connection area. Existing technology includes a patent (CN 104771817 A) that discloses a power supply protection device for wide-area electromagnetic exploration equipment. This device includes a cylinder and a first receiving hole. The first receiving hole is located inside the top of the cylinder, and a second receiving hole is located at the bottom. A fixed shaft is fixedly installed inside the second receiving hole. The fixed shaft has a through hole at its center, and a straight plate is fitted onto its outer surface. An adjustment plate is fixedly installed at the bottom of the straight plate, and the surface of the adjustment plate has a groove. This power supply protection device allows operators to use it quickly and easily by manipulating the studs. Furthermore, the pressure exerted by the push block on the adjustment plate facilitates fine-tuning and prevents overall misalignment. The device's large expansion range facilitates the separation and blocking of the line connection area, thus improving overall usability. The subsequent pressing of the straight plate by the return spring helps the adjustment plate to reset properly. However, when separating the electrical connection area of ​​the wide-area electromagnetic exploration equipment, the operator needs to manually rotate the stud. The threaded connection causes the push block to gradually move upwards, separating it from the adjustment plate. This process requires multiple rotations of the stud, which is time-consuming and inconvenient. Therefore, we propose a power supply protection device for wide-area electromagnetic exploration equipment. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2This embodiment provides a technical solution: a power supply protection device for a wide-area electromagnetic exploration equipment, including a casing 1, a connecting post 3 4 on the bottom wall of the casing 1, a connecting post 2 3 installed inside the casing 1, a connecting post 1 2 on the top wall of the casing 1, a grounding seat 5 on the lower side of the casing 1, an input terminal of the connecting post 1 2 electrically connected to an external circuit, an output terminal of the connecting post 1 2 electrically connected to the input terminals of the connecting post 2 3 and the electromagnet 63 respectively, an output terminal of the connecting post 3 4 electrically connected to the input terminal of the grounding seat 5, a polyethylene insulating shell 9 on the lower outer side of the connecting post 3 4, and a polyethylene grip sleeve 10 on the outer side of the casing 1, the polyethylene grip sleeve 10 being made of polyethylene material for insulation. The polyethylene grip sleeve 10 has evenly distributed anti-slip textures on its outer side. When using the power supply protection device of the wide-area electromagnetic exploration equipment, the worker holds the polyethylene grip sleeve 10 and inserts the ground base 5 into the soil at the measurement point. The anti-slip textures on the polyethylene grip sleeve 10 increase the contact friction between the worker's hand and the device, preventing the worker's hand from slipping when the ground base 5 is inserted into the soil. The input end of the connecting column 12 is electrically connected to the output end of the wide-area electromagnetic exploration equipment. The polyethylene insulating shell 9, with its high resistance, insulates and protects the part of the lower end of the connecting column 34 exposed into the casing shell 1. It also includes a power supply protection mechanism 6.

[0020] Power supply protection mechanism 6 includes a lower circular seat 61, an upper circular seat 62, an electromagnet 63, an iron ring 64, a first magnet 65, and a second magnet 66. The lower circular seat 61 is located on the upper outer side of the connecting post 3. The upper circular seat 62 is located on the outer side of the connecting post 3. The iron ring 64 and the second magnet 66 are located on the lower side of the upper circular seat 62. The electromagnet 63 and the first magnet 65 are located on the upper side of the lower circular seat 61. The power supply protection mechanism 6 also includes a rocker switch 67, which is connected in series to the circuit connecting the output terminal of the connecting post 2 and the input terminal of the electromagnet 63. The rocker switch 67 is fixedly connected to the outer side of the sleeve shell 1. The power supply protection mechanism 6 also includes a resistor 68, which is connected in series to the output terminal of the connecting post 2 and the input terminal of the electromagnet 63. In the electrical connection circuit, resistor 68 is fixedly connected to the inner wall of casing 1. The magnetic poles of the inner ends of magnet 65 and magnet 66 are the same. Two symmetrically distributed guide grooves 8 are opened on the inner wall of casing 1. Slide seats 7 are slidably connected inside each guide groove 8. Slide seats 7 are fixedly connected to upper circular seat 62. During normal use of the wide-area electromagnetic exploration equipment, when connecting post 2 is energized, the current supplies power to electromagnet 63. Electromagnet 63 starts to generate electromagnetic attraction. The electromagnetic attraction of electromagnet 63 to iron ring 64 is greater than the repulsive magnetic force between magnet 65 and magnet 66, thereby causing upper circular seat 62 to drive connecting post 3 to move vertically downward and contact connecting post 4, thereby supplying power to connecting post 4. During this process, upper circular seat 62 moves through... The slide block 7 slides vertically down along the guide groove 8, thereby improving the stability of the vertical sliding of the upper circular seat 62 and the connecting post 2 3. The resistor 68 is connected in series to the circuit that connects the output end of the connecting post 1 2 and the input end of the electromagnet 3, thereby reducing the input current of the electromagnet 3 and preventing the output current of the connecting post 1 2 from being too large and damaging the electromagnet 3. During the use of the power supply protection device for the wide-area electromagnetic exploration equipment, when a power supply failure occurs, the power supply to the input end of the electromagnet 3 disappears, and the electromagnetic attraction of the electromagnet 3 to the iron ring 64 disappears. At this time, through the repulsive magnetic force between magnet 1 65 and magnet 2 66, the upper circular seat 62 drives the connecting post 2 3 to move upward quickly and away from the connecting post 3 4. This device disconnects the internal circuitry, enabling automatic power disconnection protection for the wide-area electromagnetic exploration equipment. Simultaneously, when manual disconnection of the electrical connection area is required during operation, simply press the boat-shaped switch 67 to disconnect the power supply to the electromagnet 3. Then, the repulsive magnetic force between magnet 65 and magnet 66 quickly separates the connection between connecting post 3 and connecting post 4. This device employs both automatic and manual electrical disconnection methods to protect the electrical connections of the wide-area electromagnetic exploration equipment. Furthermore, by utilizing magnetic properties through a transmission element, it performs rapid electrical disconnection of the electrical connections, eliminating the need for operators to repeatedly rotate components, making operation convenient and quick.

[0021] The working principle of the power supply protection device for a wide-area electromagnetic exploration equipment provided by this utility model is as follows: When using the power supply protection device for a wide-area electromagnetic exploration equipment, hold the polyethylene handle sleeve 10 and insert the ground insertion base 5 into the soil at the measurement point. The anti-slip texture of the polyethylene handle sleeve 10 increases the contact friction between the worker's hand and the device, preventing slippage when the ground insertion base 5 is inserted into the soil. The input end of the connecting column 2 is electrically connected to the output end of the wide-area electromagnetic exploration equipment. During normal use of the wide-area electromagnetic exploration equipment... In the middle, when connecting post 2 is energized, the current supplies power to electromagnet 63, which generates an electromagnetic attraction. The electromagnetic attraction of electromagnet 63 to iron ring 64 is greater than the repulsive magnetic force between magnet 65 and magnet 66, causing the upper circular seat 62 to move connecting post 3 vertically downwards and into contact with connecting post 4, thus supplying power to connecting post 4. During this process, the upper circular seat 62 slides vertically down along guide groove 8 via slide block 7. The sliding guide improves the stability of the vertical sliding of connecting post 3 driven by the upper circular seat 62. Resistor 68 is connected in series to connecting post 2. The output terminal of the electromagnet 3 is electrically connected to the input terminal of the electromagnet 3 in the circuit, thereby reducing the input current of the electromagnet 3 to prevent the output current of the connecting post 2 from being too large and damaging the electromagnet 3. The polyethylene insulating shell 9, with its high resistance, insulates and protects the part of the lower end of the connecting post 3 4 exposed inside the sleeve shell 1. During the use of the power supply protection device for the wide-area electromagnetic exploration equipment, when a power supply failure occurs in the wide-area electromagnetic exploration equipment, the input current of the electromagnet 3 disappears, and the electromagnetic attraction of the electromagnet 3 to the iron ring 64 disappears. At this time, the magnet... The repulsive magnetic force between magnet 65 and magnet 66 causes the upper circular seat 62 to move the connecting post 3 upwards quickly, thus moving it away from the connecting post 4. This disconnects the internal circuit of the device, enabling automatic power disconnection protection for the wide-area electromagnetic exploration equipment. Furthermore, when the power supply protection device requires manual disconnection of the electrical connection area, simply press the boat-shaped switch 67 to disconnect the power supply to electromagnet 3. Subsequently, the repulsive magnetic force between magnet 65 and magnet 66 causes the connecting post 3 to quickly disconnect from the connecting post 4, making the operation convenient and quick.
