Specific embodiments
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-4 , the present utility model provides a metal detector for geological exploration, including an assembling frame 1. A strengthening seat 2 for preventing bending is installed on the outer side of the assembling frame 1. A connecting seat 3 is installed on the outer side wall of the strengthening seat 2. A damping rotating sphere 4 is embedded at one end of the connecting seat 3 away from the strengthening seat 2. A support rod 5 is installed on the outer wall of the damping rotating sphere 4. One end of the support rod 5 away from the damping rotating sphere 4 is installed with a damping hinge 7, and a extending handle frame 6 for holding is installed at the movable end of the damping hinge 7. A splicing device for adjusting the splicing detection range is arranged between adjacent assembling frames 1. A wire is arranged inside the assembling frame 1, and the wire extends to the outer surface of the assembling frame 1 through a conductive contact.
[0022] Furthermore, the splicing device includes a damping gasket ring 8, a conductive ring seat 9, a screw hole 10, a positioning perforation 11, a bearing gasket ring 12, a fastening bolt 13 and a conductive copper ring 14. The damping gasket ring 8 is arranged at the connecting position of the ends between adjacent assembling frames 1 for supporting the assembling frame 1. The conductive ring seat 9 is arranged inside the damping gasket ring 8. Conductive copper rings 14 are installed at the top and bottom of the conductive ring seat 9. A conductive contact is installed at the position where the assembling frame 1 contacts the conductive copper ring 14, and the conductive contact contacts the conductive copper ring 14. The screw hole 10 is opened at the top of the lower assembling frame 1, the positioning perforation 11 is opened at the top of the upper assembling frame 1, the bearing gasket ring 12 is installed inside the positioning perforation 11, and the fastening bolt 13 passes through the positioning perforation 11 and is threadedly connected to the lower assembling frame 1 through the screw hole 10. The detector with different detection range sizes is assembled through the cooperation of the splicing device and the assembling frame 1.
[0023] Further, the conductive contact is made of a bent copper sheet. The conductive contact contacts the conductive copper ring 14. When the assembling frame 1 rotates, it drives the conductive contact to move along the bottom annular track of the conductive copper ring 14, so that the conductive contact can always be in contact with the conductive copper ring 14, thereby ensuring that the conductive circuit inside the assembling frame 1 remains unobstructed when the assembling frame 1 is assembled at different angles, and maintaining the generation of the magnetic field inside the detector.
[0024] Further, there are several assembling frames 1, which are connected end to end through a splicing device to form a sealed ring. The wires inside the assembling frame 1 are electrically connected to form a ring. The current in the ring state will generate a magnetic field, so that detection work can be carried out through the change of the magnetic field.
[0025] Further, rubber gaskets are provided at the positions where the inner wall of the connecting seat 3 contacts the damping rotating sphere 4, and at the positions where the two rotating plates inside the damping hinge 7 contact each other. Annular rubber gaskets are provided at the top and bottom of the damping gasket ring 8. By providing resistance through the rubber gaskets, the connecting seat 3 and the damping rotating sphere 4, as well as the support rod 5 and the extended handle frame 6, can maintain a stable angle for detection work without external force.
[0026] Further, rubber sealing rings for insulation are provided on the surface of the conductive ring seat 9 on both the inner and outer sides of the conductive copper ring 14 and between adjacent conductive copper rings 14, to prevent internal leakage of electricity, and at the same time prevent the current between adjacent wires inside the assembling frame 1 from generating parallel connection and affecting the stability of the magnetic field.
[0027] During use, the number of assembling frames 1 for assembly is selected according to the on-site environment. When assembling, the conductive ring seat 9 and the damping gasket ring 8 are pressed at the crimping position between the two assembling frames 1. The fastening bolts 13 pass through the positioning perforations 11, and the fastening bolts 13 are threadedly connected to the screw holes 10 to connect and install the adjacent assembling frames 1. The conductive contacts at the ends of the assembling frames 1 are pressed against the conductive copper rings 14 on the surface of the conductive ring seat 9. In the same way, the required assembling frames 1 are connected end to end to form a ring. During use, the current passes through the wires inside the assembling frame 1, and then is transmitted to the inside of the adjacent assembling frame 1 through the cooperation of the conductive contacts and the conductive copper rings 14. Finally, the current forms a circular flow path along the wires inside the assembling frame 1, generating a magnetic field inside the assembling frame 1. Metal detection work is carried out through the change of the magnetic field. During the use process, the angles between the support rod 5 and the extended handle frame 6 and between the connecting seat 3 and the support rod 5 can be adjusted for use, so as to be applicable to different use environments.
[0028] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
