DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] like Figures 1 to 7 As shown, the geological and mineral exploration equipment of the present invention comprises:

[0039] An electromagnetic instrument 1, wherein a base 2 is fixedly connected to the lower side of the electromagnetic instrument 1; a group of electrode arms 3 are evenly distributed on the side of the electromagnetic instrument 1, and the electrode arms 3 are usually elastic; an electrode head 4 is fixedly connected to the end of the electrode arm 3;

[0040] A protective cover 5, wherein a group of protective covers 5 are provided and respectively sleeved on the outside of the electrode arm 3, and the protective cover 5 may have a certain elasticity; the protective cover 5 is fixedly connected to the electromagnetic instrument 1; a notch is provided at the bottom of the protective cover 5; an annular groove 6 is provided inside the protective cover 5; a fixing block 7 is provided at the top of the annular groove 6; a pair of arc-shaped plates 8 are slidably connected to the bottom of the annular groove 6; a group of arc-shaped telescopic sleeves 9 and springs 10 are fixedly connected between the arc-shaped plates 8 and the fixing blocks 7; the telescopic sleeves 9 are shortened by vacuuming the air through the vacuum assembly.

[0041] In the prior art, the electrode arm 3 of the seabed electromagnetic instrument 1 is usually exposed and lacks certain protection measures. Therefore, when the electromagnetic instrument 1 is placed on the seabed, the electrode arm 3 is very likely to collide with hard objects such as rocks and coral reefs on the seabed, causing the electrode arm 3 to break or the electrode head 4 to be damaged, making the electromagnetic instrument 1 unusable subsequently.

[0042] During the deployment of the electromagnetic instrument 1 in the present invention, the electrode arm 3 and the electrode head 4 are both located inside the protective cover 5, and the notch at the bottom of the protective cover 5 is in a closed state, so as to protect and buffer the electrode arm 3 and the electrode head 4 and prevent them from being damaged by colliding with hard objects such as rocks and coral reefs during the sinking process. When the electromagnetic instrument 1 reaches the seabed, the air inside the telescopic sleeve 9 is sucked by the vacuum assembly, so that the telescopic sleeve 9 is shortened and the arc plate 8 is driven to slide into the annular groove 6, and then a pair of arc plates 8 are separated from each other and the bottom of the protective cover 5 is opened, and the electrode arm 3 bends downward under the action of its own gravity and makes the electrode head 4 fit the surface of the seabed rock and soil, so that it can work normally afterwards.

[0043] The vacuum assembly includes a negative pressure groove 11 opened inside the base 2; a slide plate 12 is slidably and sealedly connected inside the negative pressure groove 11; an elastic member 13 is fixedly connected between the slide plate 12 and the negative pressure groove 11; a connecting rod 14 is fixedly connected to the lower side of the slide plate 12; a pressing plate 15 is fixedly connected to one end of the connecting rod 14 extending below the base 2, and the connecting rod 14 is slidably and sealedly connected to the base 2; the bottom of the negative pressure groove 11 and the telescopic sleeve 9 are interconnected through a conduit 16. When the electromagnetic instrument 1 sinks to the seabed, the base 2 and the seabed rock and soil squeeze each other, driving the pressing plate 15 to move upward, and driving the slide plate 12 to slide upward inside the negative pressure groove 11 through the connecting rod 14, thereby generating negative pressure at the bottom of the negative pressure groove 11, and sucking the air inside the telescopic sleeve 9 through the conduit 16, so that the electromagnetic instrument 1 automatically opens the bottom of the protective cover 5 after sinking and allows the electrode head 4 to fit with the seabed rock and soil, thereby improving the automation of the device.

[0044] The base 2 has a groove 17 at the corresponding position of the pressing plate 15. The groove 17 allows the pressing plate 15 to be stored inside the groove 17 after moving upward, preventing the pressing plate 15 from protruding from the surface of the base 2 and causing the electromagnetic instrument 1 to be unstable and tilted.

[0045] As a preferred embodiment of the present invention, a pair of guide holes 18 are provided between the top of the annular groove 6 and the inner side of the protective cover 5; a roller 19 is rotatably connected to the top of the guide hole 18; a pull rope 20 is fixedly connected to the upper side of the arc plate 8, and the other end of the pull rope 20 is fixedly connected to the top of the electrode head 4 after passing through the roller 19 and the guide hole 18. When the electromagnetic instrument 1 is subsequently recovered, the base 2 leaves the seabed surface, and the elastic member 13 drives the slide plate 12 to reset downward, then the spring 10 pushes the arc plate 8 to slide out of the annular groove 6, and then the arc plate 8 pulls the electrode head 4 upward through the pull rope 20, and the electrode head 4 and the electrode arm 3 are re-entered into the protective cover 5. At the same time, the pair of arc plates 8 are closed and the bottom of the protective cover 5 is closed, so that the electromagnetic instrument 1 can also prevent the electrode arm 3 and the electrode head 4 from colliding with hard objects during the ascent and recovery process, thereby achieving all-round protection for the electrode arm 3 and the electrode head 4.

[0046] The guide hole 18 is fixedly connected with a partition 21; a through hole 22 is formed on the surface of the partition 21, and the pull rope 20 passes through the through hole 22; a group of elastic balls 23 are evenly distributed on the surface of the pull rope 20, and the size of the elastic balls 23 is larger than the through hole 22. In the process of the pull rope 20 pulling the electrode head 4 upward, multiple elastic balls 23 will intermittently pass through the partition 21, and then the through hole 22 squeezes and deforms the elastic balls 23, and when the elastic balls 23 completely pass through the through hole 22, an acceleration effect will be obtained in a short time, so that the pull rope 20 is used to drive the electrode head 4 and the electrode arm 3 to stop and shake, promote the shedding of debris on the surface of the electrode head 4 and the electrode arm 3, such as rock soil or various attached marine organisms, etc., and improve the cleanliness of the equipment during recycling.

[0047] As a preferred embodiment of the present invention, an annular frame 24 is fixedly connected to the outside of the base 2; a group of connecting ropes 25 are evenly distributed on the upper side of the annular frame 24; and a floating ball 26 is fixedly connected to the upper end of the connecting rope 25. By providing the annular frame 24, the stability of the electromagnetic instrument 1 when it is grounded and working is further improved, and the connecting rope 25 is straightened upward by the floating ball 26 to form an annular isolation zone outside the electromagnetic instrument 1, and the floating ball 26 and the connecting rope 25 can swing under the action of the water flow, which is conducive to preventing large marine animals around from approaching the electromagnetic instrument 1 and causing interference or damage to the electromagnetic instrument 1, thereby ensuring the smooth progress of the survey work of the electromagnetic instrument 1.

[0048] The upper side of the annular frame 24 is fixedly connected with an annular rod 27; a group of mounting blocks 28 are fixedly connected to the surface of the annular rod 27; the surfaces of the annular rod 27 on both sides of the mounting blocks 28 are slidably connected with movable seats 29; the connecting rope 25 is evenly distributed on the surface of the movable seat 29; an arc-shaped telescopic sleeve 2 30 and a spring 2 31 are fixedly connected between the movable seat 29 and the mounting block 28; the telescopic sleeve 2 30 is inflated and extended by the inflatable component. During the normal working process of the electromagnetic instrument 1, the inflatable component is intermittently inflated into the telescopic sleeve 2 30, the telescopic sleeve 2 30 is controlled to extend and cooperate with the spring 2 31, so that the movable seat 29 slides back and forth on the surface of the annular rod 27, thereby further allowing the connecting rope 25 and the floating ball 26 to swing continuously, thereby improving the effect of scaring away nearby marine animals.

[0049] The inflatable assembly includes a floating platform 32; a group of side grooves 33 are evenly distributed on the surface of the floating platform 32; a floating plate 34 is hinged inside the side groove 33 through a rotating pin and a torsion spring; an elastic air storage member 35 is fixedly connected between the floating plate 34 and the bottom of the side groove 33; the air storage member 35 and the telescopic sleeve 2 30 are connected to each other through a conduit 2 36. The floating platform 32 floats on the sea surface, and the floating plate 34 is constantly deflected and squeezes the air storage member 35 under the action of the waves, and the air inside the air storage member 35 is squeezed into the interior of the telescopic sleeve 2 30 through the conduit 2 36, and cooperates with the spring 2 31 to realize the reciprocating motion of the movable seat 29, thereby using wave energy to drive the connecting rope 25 and the floating ball 26, thereby improving the energy-saving effect of the device, and the driving method is long-lasting and durable, which is conducive to long-term and stable prevention of various marine animals from approaching.

[0052] S2: When the electromagnetic instrument 1 sinks to the seabed, the slide plate 12 is driven to slide upward inside the negative pressure groove 11 through the pressure plate 15 and the connecting rod 14, so that negative pressure is generated at the bottom of the negative pressure groove 11, and the air inside the telescopic sleeve 9 is sucked through the conduit 16 to shorten it;

[0053] S3: The telescopic sleeve 9 drives the arc plate 8 to slide into the annular groove 6, and then the pair of arc plates 8 separate from each other and open the bottom of the protective cover 5. The electrode arm 3 bends downward under the action of its own gravity and makes the electrode head 4 fit the seabed rock surface;

[0054] S4: The floating platform 32 floats on the sea surface, and the floating plate 34 is continuously deflected and squeezes the air storage member 35 under the action of the waves, so that the air inside the air storage member 35 is squeezed into the interior of the telescopic sleeve 2 30 through the conduit 2 36 and stretches it;

[0055] S5: The telescopic sleeve 2 30 cooperates with the spring 2 31 to realize the reciprocating motion of the movable seat 29, so as to cause the connecting rope 25 and the floating ball 26 to swing continuously, thus scaring away nearby marine animals and preventing interference to the electromagnetic instrument 1.
