Description

Technical Field

[0001] The invention relates to the technical field of geological survey, and in particular to an offshore geological survey early warning device. Background Art

[0002] Geological exploration, also known as geological survey, is aimed at understanding underground structures, rock properties, hydrological conditions and possible mineral resources through systematic investigation and analysis. These technologies are not only crucial to the safety and feasibility of construction projects, but also play an indispensable role in finding and evaluating natural resources. The "Haimai" submarine seismic exploration and acquisition equipment is a node-based seismic exploration and acquisition equipment independently developed and manufactured by China. The main application scenario of "Haimai" is to conduct submarine seismic exploration in marine oil and gas exploration. Thousands of "Haimai" nodes are regularly deployed at designated locations on the seabed through professional retractable equipment to form a huge monitoring network. When the operation is completed, technicians will retrieve them, download and analyze the collected data information, and then process them into seismic profiles to achieve accurate "pulse" of the strata. This technology can significantly improve the accuracy of oil and gas exploration and development, and help discover oil and gas reservoir information in deeper strata and complex geological structures.

[0003] After existing surveying equipment sinks to the bottom of the sea and collects geological information, it needs to be salvaged. The existing salvage method is to use a rope to tie the front end of the surveying equipment and put it into the water, and then mark it for easy salvage. However, the rope will be corroded by the erosion of sea water, causing the rope to become fragile. When the surveying equipment is lifted again, there is a risk of the rope breaking easily. Secondly, the position of the surveying equipment may be offset by the undercurrent in the sea, resulting in errors in the survey information. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1: An offshore geological survey early warning device, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, it includes a sea vein geophysical surveyor 1, an iron ring 101, a fixing plate 9, a protective cover 901, a fixing rod 10, an air bag 11, a connecting rope 12, a compressed gas tank 13, a solenoid valve 14 and a connecting pipe 15. The front side of the sea vein geophysical surveyor 1 is symmetrically provided with an iron ring 101 for lifting, and the top middle part of the sea vein geophysical surveyor 1 is fixed with a fixing plate 9 by bolts. The fixing rods 10 are symmetrically arranged on the front and rear sides of the top of the fixing plate 9. The shape of the fixing rod 10 in the front view is an inverted L shape, and the L-shaped fixing plate is a Y shape when viewed from the top view. The symmetrical fixing rods 10 are detachably connected to an airbag 11, and an air inlet port is symmetrically arranged at the bottom of the airbag 11, and the air inlet port is detachably connected to the Y-shaped port at the top of the symmetrical L-shaped fixing rod 10, and the airbag 11 is equidistant and symmetrically arranged with four connecting ropes 12 along its circumference, and the connecting ropes 12 are arranged at the four corners of the airbag 11, one end of the connecting rope 12 is connected to the airbag 11, and the other end thereof is connected to the top of the sea vein geophysical surveyor 1 at a 45 degree angle outward toward the direction of the sea vein geophysical surveyor 1, thereby forming a A flat-top trapezoid is formed to ensure that the tension of each connecting rope 12 is equal when the airbag 11 is inflated. Compressed gas tanks 13 are arranged in a central rotationally symmetrical manner on the left and right sides of the top of the fixing plate 9, wherein the exhaust end of the compressed gas tank 13 on the left faces forward, and the exhaust end of the other compressed gas tank 13 faces backward. The exhaust ports of the central rotationally symmetrical compressed gas tanks 13 are all provided with electromagnetic valves 14 for controlling exhaust, and the exhaust ports of the symmetrical compressed gas tanks 13 are all provided with connecting pipes 15, and the ends of the connecting pipes 15 away from the compressed gas tanks 13 are respectively connected to the airbags The connecting tube 15 disposed on the compressed gas tank 13 on the left side of the fixing plate 9 is connected to and communicated with the air inlet port on the rear side of the bottom of the airbag 11 at one end away from the compressed gas tank 13; the connecting tube 15 disposed on the compressed gas tank 13 on the right side of the fixing plate 9 is connected to and communicated with the air inlet port on the front side of the bottom of the airbag 11 at one end away from the compressed gas tank 13; a protective cover 901 is rotationally symmetrically provided at the center of the top of the fixing plate 9, and the symmetrical protective cover 901 protects the compressed gas tank 13 from sealing.

[0031] like Figure 1 , Figure 5 and Figure 8 As shown, it also includes a protective frame 17, a limiting plate 1701, a rotating plate 18 and a torsion spring 19. A protective frame 17 is arranged on the top of the sea vein exploration device 1. A rotating plate 18 is symmetrically and rotatably arranged on the top of the protective frame 17. A torsion spring 19 is arranged at the rotating connection between the rotating plate 18 and the protective frame 17.

The protective frame 17 encloses all the components arranged on the fixed plate 9 and is closed by the symmetrical rotating plate 18 to form a closure.

[0032] When the geological information survey of the designated sea area is completed and the sea vein geophysical survey device 1 needs to be salvaged, the solenoid valve 14 is opened through the program. At this time, the high-pressure gas in the compressor tank inflates the airbag 11 through the connecting pipe 15. At this time, the airbag 11 continues to expand, and under the action of the gas buoyancy, it squeezes the rotating plate 18 and separates from the fixed rod 10. The rotating plate 18 rotates and opens along both sides of the protective frame 17, and the sea vein geophysical survey device 1 is pulled out from the seabed through the connecting rope 12. At the same time, the buffer plate 4 is reset under the elastic force of the compressed state of the first spring 3, and the side nail 6 is pushed to slide and reset along the second guide rod 7 into the insertion nail 5, and the grip of the side nail 6 on the seabed is released. At this time, the airbag 11 is continuously inflated.

[0033] Embodiment 2: Based on embodiment 1, Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, it also includes a first guide rod 2, a first spring 3, a buffer plate 4 and a weight 16. Two groups of first guide rods 2 are symmetrically arranged on both sides of the top of the sea vein geophysical surveyor 1, wherein two first guide rods 2 form a group, and the left and right sides of the top of the sea vein geophysical surveyor 1 are respectively a group, and each first guide rod 2 is symmetrically arranged front and back and left and right, and the shape of the first guide rod 2 is N-shaped, and the bottom of the N-shaped first guide rod 2 is downwardly connected to the top of the sea vein geophysical surveyor 1, and the bottom of the sea vein geophysical surveyor 1 is slidably provided with a buffer plate 4, and the two sides of the buffer plate 4 extend to the two sides of the sea vein geophysical surveyor 1, and a group of extensions are respectively extended on both sides. The extension plates are grouped into two each, and the buffer plate 4 is grouped on each side. The top of the extension plate is in an inverted L-shape and is slidably connected to the N-shaped first guide rod 2. The positions of the first guide rod 2 and the extension plate correspond to each other. A first spring 3 is arranged between the first guide rod 2 and the L-shaped portion of the extension plate extending from the buffer plate 4, and the first spring 3 is sleeved on the first guide rod 2. Two first springs 3 are sleeved on the N-shaped first guide rod 2. Five counterweights 16 are equidistantly arranged on the bottom of the buffer plate 4 at front and back, and the lengths of the counterweights 16 on the outermost sides of the front and back are greater than the counterweights 16 in the middle.

[0034] like Figure 3 , Figure 4 and Figure 7As shown, it also includes a pin 5, a side pin 6, a second guide rod 7 and a second spring 8. Four pins 5 are symmetrically and equidistantly arranged at the bottom of the sea vein exploration device 1. Second guide rods 7 are symmetrically arranged on the left and right sides of the pin 5. The two second guide rods 7 form a group, and there are two groups on each pin 5. Side pins 6 are symmetrically and slidably arranged on both sides of the pin 5, and the side pins 6 are slidably installed on the second guide rod 7. A second spring 8 is arranged between the side pin 6 and the pin 5, and the second spring 8 is sleeved on the second guide rod 7.

[0035] When it is necessary to survey the internal geological information in a designated sea area, the iron ring 101 at the front end of the sea vein geophysical surveyor 1 is marked, and then the sea vein geophysical surveyor 1 sinks to the seabed. At this time, the sea vein geophysical surveyor 1 will drop horizontally under the gravity of the counterweight block 16. When the sea vein geophysical surveyor 1 reaches the seabed, the pins 5 at its bottom will be inserted into the seabed, and then the seabed plane squeezes the buffer plate 4 to slide upward along the first guide rod 2. At this time, the first spring 3 is compressed, and at the same time, the side pins 6 are pushed out under the action of the elastic force of the second spring 8, and the side pins 6 slide outward along the second guide rod 7. The side pins 6 are inserted into the seabed to increase the fixing effect and prevent the position of the sea vein geophysical surveyor 1 from shifting.

[0036] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention.
