Description

Technical Field

[0001] The invention relates to the technical field of marine environment detection and collection, and in particular to a visual multi-tube sampler. Background Art

[0002] The multi-tube sampler is a classic bottom sediment sampling device. It has the characteristics of buffered static pressure penetration sediment sampling after landing and stationing, as well as adsorption-type upper seal and insertion-type lower seal. One sampling can usually obtain 8 tubes of low-disturbance bottom sediments and unexchanged overlying water samples. It is suitable for sediment and overlying water sampling in the entire ocean and estuaries. It can fully meet the research needs of environmental projects such as marine engineering geology, biology, chemistry, geotechnical and ecological changes, and is an essential equipment for bottom sediment investigation and research in the ocean and estuaries.

[0003] The visual multi-tube sampler is equipped with an underwater high-definition visual system on the conventional multi-tube sampler. The visual system is lowered to the seabed with the sampler and communicates with the deck control end. After the visual system is installed, relevant personnel can observe the seabed topography and sampling process in real time on the deck display screen, realizing target sampling under visual conditions.

[0004] The existing visual multi-tube sampler is generally modified by simply adding visual hardware to a conventional multi-tube sampler without a visual system. Its underwater control center is installed on the upper platform of the support frame, and underwater cameras, underwater lighting, altimeters and other components are simply fixed on the legs or crossbars of the support frame. Such a setting has the following disadvantages: 1. Because the equipment hanging point and the support frame have relative movement, when the hanging point and the support frame are close to each other, the connecting cable from the hanging point to the underwater control center will be in a free state without tension or fixation, which is extremely random in the complex seabed environment and is very easy to be scratched and damaged or even broken by the moving parts of the equipment itself; 2. Because the underwater camera, underwater lighting, altimeter and other components are simply fixed on the support frame, there is no condition for particularly effective protection, and the support frame itself is a protective structure. During the deployment, recovery, and bottom sampling process, they are often hit by the ship's side and the seabed structure. Therefore, the underwater camera, underwater lighting, altimeter, etc., and even the connecting cable between them and the underwater control center are easily damaged due to accidental collisions with themselves or the support frame during the above process; 3. Due to the installation position restrictions, no matter how the underwater camera is arranged, either the field of view area is poor or there is a serious obstruction; 4. During the lowering process, due to the combined effects of the impact of the water flow and the ups and downs of the hanging ship, the trigger switch of the acquisition head is often triggered by mistake, resulting in sampling failure. Summary of the invention

[0005] In view of the defects existing in the prior art, the purpose of the present invention is to provide a visual multi-tube sampler that can improve the working conditions of the connecting cables to prevent accidental scratches, provide effective protection for various electrical components and their connecting cables, and obtain better video data of the operation process, and has higher reliability and sampling success rate.

DETAILED DESCRIPTION

[0034] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0035] See also Figure 1 and Figure 2 As shown, the embodiment of the present application provides a visual multi-tube sampler, including a ballast lead block 1, a collection frame 2, an underwater control center 4, a collection head 5 and a support frame 6. The top of the collection frame 2 is provided with a load-bearing head docking plate 21, and the bottom is provided with a comprehensive mounting plate 22. Figure 3 As shown, the integrated mounting plate 22 is provided with an underwater control center mounting position 221 and a ballast lead block mounting position 222, and the ballast lead block mounting position 222 is used to fix the ballast lead block 1; the bottom of the bearing head docking plate 21 is provided with a fairlead 3 extending toward the integrated mounting plate 22, see Figure 4 As shown, the outer wall of the fairlead 3 is provided with a longitudinally penetrating opening 31, and the fairlead 3 is used to accommodate the armored cable core cable between the bearing head assembly and the oil-filled junction box; the underwater control center 4 is arranged on the underwater control center installation position 221, and is used to realize the functions of communication, power transmission and transformation, signal acquisition, encoding and decoding, underwater electrical component control, etc.; see Figure 5As shown, the collection head 5 includes a central axis frame 51, a collection head frame 52, multiple sampling mechanisms 53, an underwater camera 54, an underwater lighting lamp 55 and an altimeter 56. The central axis frame 51 is fixed to the bottom of the integrated mounting plate 22, the collection head frame 52 is slidably sleeved outside the central axis frame 51, multiple sampling mechanisms 53 are arranged on the surrounding side of the collection head frame 52, the underwater camera 54, the underwater lighting lamp 55 and the altimeter 56 are all arranged inside the central axis frame 51 and the underwater camera 54 is located at the center of the bottom of the central axis frame 51, the underwater camera 54, the underwater lighting lamp 55 and the altimeter 56 are connected to the underwater control center 4 through a combined connecting cable; the support frame 6 is sleeved outside the collection head 5, and includes a leg connecting plate 61 and a plurality of legs 62 fixed to the bottom of the leg connecting plate 61; wherein, the integrated mounting plate 22 is located inside the support frame 6, and the leg connecting plate 61 can move in a direction away from or close to the integrated mounting plate 22.

[0036] The existing underwater control center 4, oil-filled junction box, underwater camera 54, underwater lighting 55 and altimeter 56 are arranged on the support frame 6. When the visual multi-tube sampler touches the bottom and performs penetration sampling, the collection frame 2 slides downward along the support frame 6, the bearing head assembly and the oil-filled junction box approach each other, and the armored cable core cable therebetween changes from a tensioned or approximately tensioned state to a loose and bent random state; after the sampling is completed, the collection frame 2 slides downward and upward along the support frame 6, the bearing head assembly moves away from the oil-filled junction box, and the armored cable core cable therebetween will resume a tensioned or approximately tensioned state again. At this time, if the armored cable core cable is affected by external factors such as water flow in a random bending state and hangs on a certain structure of the sampler itself or is stuck between relatively sliding parts, it will be damaged or even broken. In addition, repeated bending and tensioning will seriously affect the service life of the armored cable core cable. The load-bearing head docking plate 21, the integrated mounting plate 22 and the center axis frame 51 are rigidly fixed. By arranging the underwater control center 4 and the oil-filled junction box on the integrated mounting plate 22, and arranging the underwater camera 54, the underwater lighting 55 and the altimeter 56 in the center axis frame 51, there is no relative movement between the load-bearing head assembly and the oil-filled junction box, between the oil-filled junction box and the underwater control center 4, and between the underwater control center 4 and the underwater camera 54, the underwater lighting 55 and the altimeter 56 during the entire sampling process. It only needs to be simply fixed to each connecting cable before lifting the equipment, so that it will not be damaged or broken due to accidental hanging or jamming, and its service life will not be affected by repeated bending and tensioning.

[0037] The underwater camera 54, underwater lighting 55 and altimeter 56 are centrally installed in the central axis frame 51, and have excellent protection performance; the underwater camera 54 is installed at the bottom center of the central axis frame 51 of the equipment and shoots downward, which can obtain ideal unobstructed video images of the sample area and can simultaneously monitor the sealing conditions of the sampling tubes on all sampling mechanisms 53 in real time.

[0038] For further information, see Figure 4As shown, a plurality of limiting structures 7 are provided in the cable guide tube 3, and the limiting structures 7 are used to limit the armored cable core cable to be located in the cable guide tube 3. Preferably, the limiting structures 7 can be embedded limiting blocks, or can be external grooves and cable ties of the cable guide tube 3, or can be other forms, but they cannot exceed the outer contour of the cable guide tube 3. Through the setting of the limiting structures 7, the opening 31 of the cable guide tube 3 can be temporarily closed during sampling without affecting the assembly and disassembly of the armored cable core cable between the load-bearing head assembly and the oil-filled junction box, thereby ensuring that the armored cable core cable arranged in the cable guide tube 3 will not jump out of the cable guide tube 3 due to the existence of the opening 31 on the cable guide tube 3 during the descent of the visual multi-tube sampler.

[0039] See also Figure 4 As shown, the leg connecting plate 61 is provided with a first through hole 611 and a cable opening 612, the first through hole 611 is used for the cable guide 3 to slide through, the cable opening 612, the first through hole 611 and the opening 31 on the cable guide 3 are interconnected, and the armored cable core cable can be inserted into or removed from the cable guide 3 through the opening 31 and the cable opening 612. Preferably, the opening 31 and the cable opening 612 are both opened radially outward from the sampler.

[0040] See also Figure 5 and Figure 6 As shown, the central axis frame 51 includes a central axis 511, a top plate 512, a plurality of support rods 513 and a bottom plate 514. The central axis 511 has a hollow core. The central axis 511 is located above the top plate 512 and is fixedly connected to the top plate 512. The top plate 512 is fixedly connected to the bottom plate 514 through a plurality of support rods 513. The bottom plate 514 is provided with an underwater camera mounting hole, an underwater lighting mounting hole and an altimeter mounting hole. The underwater camera mounting hole is located at the center of the bottom plate 514, and the underwater lighting mounting hole and the altimeter mounting hole are arranged on both sides of the underwater camera mounting hole. By setting the bottom plate 514, the underwater camera 54, the underwater lighting 55 and the altimeter can be mounted. The underwater camera 54, the underwater lighting light 55 and the altimeter 56 are fixed, and the underwater camera 54, the underwater lighting light 55 and the altimeter 56 pass through the bottom plate 514 to work downward; the forked ends of the combined connecting cable between the underwater camera 54, the underwater lighting light 55 and the altimeter 56 and the underwater control center 4 are respectively plugged with the underwater camera 54, the underwater lighting light 55 and the altimeter 56, and the single head end passes through the axis core of the central axis 511 from bottom to top and then is plugged with the underwater control center 4; at the same time, the underwater camera 54, the underwater lighting light 55 and the altimeter 56 are located between the top plate 512 and the bottom plate 514, so as to further complete the protection of the underwater camera 54, the underwater lighting light 55 and the altimeter 56 and improve the overall protection performance.

[0041] By setting up the altimeter 56, underwater lighting 55 and underwater camera 54, the sampling process can be monitored, and the target area can be observed in real time before sampling, thereby improving the operability of the sampler and the effectiveness of the sample.

[0042] See also Figure 5 As shown, the collection head frame 52 includes a multi-tube trigger mechanism, a middle axis sleeve 521 and a middle axis frame cover 522 connected to the middle axis sleeve 521. The middle axis sleeve 521 is sleeved outside the middle axis 511, and the middle axis frame cover 522 is sleeved outside the top plate 512 and the support rod 513. The multi-tube trigger mechanism is arranged on the middle axis sleeve 521, and multiple sampling mechanisms 53 are fixed around the outer wall of the middle axis frame cover 522.

[0043] The visual multi-tube sampler also includes an anti-mis-triggering device 8, which is arranged between the top plate 512 and the bottom plate 514 of the central axis frame 51 and is connected to the underwater control center 4 through a combined connecting cable. Figure 7 As shown, the inner wall of the middle axis frame cover 522 is provided with a first annular groove 5221. When the sampler is lowered, the operator on the deck side controls the push pin of the anti-mis-triggering device 8 to be pushed out, and the push pin extends into the first annular groove 5221, and the collection head frame 52 is locked with the middle axis frame 51, ensuring that the collection head frame 52 will not be affected by environmental factors such as water flow and slide up and down abnormally with the middle axis frame 51 to erroneously trigger the multi-tube trigger mechanism; when sampling, the operator on the deck side controls the push pin of the anti-mis-triggering device 8 to retract, and the collection head frame 52 and the middle axis frame 51 are unlocked, so that the sampling action can be completed normally.

[0044] See also Figure 1 and Figure 2 As shown, the integrated mounting plate 22 is also provided with an oil-filled junction box mounting position 223, and the oil-filled junction box mounting position 223 is provided with a mounting top plate 9, which is fixed to the integrated mounting plate 22 by a plurality of columns 10; the mounting top plate 9 divides the oil-filled junction box mounting position 223 into two layers, the lower layer is used to accommodate the oil box body, and the upper layer is used to install the oil compensator. Preferably, there are 4 columns 10, which are rectangularly distributed outside the four corners of the rectangular oil-filled junction box body. Preferably, the oil compensator mounting interface on the mounting top plate 9 is installed horizontally for the oil compensator.

[0045] In the prior art, the end of the round tube is usually fixed to the flat plate by welding a flange plate or directly welding. However, if the central axis 511 is fixed to the integrated mounting plate 22 by conventional means, it is necessary to insert the collection head frame 52 into the central axis frame 51 before welding, which will cause the central axis frame 51 to be unable to be removed from the collection head 5 without damaging the structure, which is not conducive to the installation, commissioning and maintenance of the collection head 5, especially the electrical components inside the central axis frame 51. Preferably, see Figure 3 and Figure 8As shown, the center of the integrated mounting plate 22 is provided with a second through hole 224, whose diameter is equal to the outer diameter of the central axis 511 of the collection head 5. The central axis 511 passes through the second through hole 224 from bottom to top and is fixed to the integrated mounting plate 22 through the petal block 11. The petal block 11 is fixed to the integrated mounting plate 22 by a number of screws, which is conducive to the installation, debugging and maintenance of the collection head 5, especially the electrical components inside the central axis frame 51. Furthermore, a positioning port and a cable outlet are provided at the upper end of the central axis 511, and a second annular groove 5111 is provided on the outer wall of the central axis 511 near the positioning port and the cable outlet (see Figure 5 As shown), a plurality of petal-dividing blocks 11 form a complete annular shape, which are respectively fixed to the integrated mounting plate 22 by screws; an annular boss is provided on the lower inner wall of the petal-dividing block 11, which can just be inserted into the second annular groove 5111 of the central axis 511; see Figure 8 As shown, the petal block 11 is provided with a radially protruding positioning tongue 111, which can just be inserted into the positioning hole at the top of the central axis 511 and does not exceed the inner wall of the central axis 511; a cable groove 112 is radially opened outward on the upper half plane of the petal block 11, and its orientation and size match the cable hole at the top of the central axis 511.

[0046] See also Figure 3 As shown, a vacant area is provided on the integrated mounting plate 22, and a plurality of third through holes 225 are provided in the vacant area. The setting of the third through holes 225 can reduce the resistance of the integrated mounting plate 22 during the descent of the visual multi-tube sampler, and the setting of the third through holes 225 can also be used to fix the armored cable core cable between the load-bearing head assembly and the oil-filled junction box, the cable and optical cable between the oil-filled junction box and the underwater control center 4, and the combined connecting cable between the underwater control center 4 and the underwater camera 54, underwater lighting 55, altimeter 56, and anti-false triggering device 8.

[0047] See also Figure 1 As shown, a detachable leg ballast lead 12 is provided at the bottom of the leg 62, in order to prevent the support frame 6 from moving upward due to the upward impact of the water flow before the sampler touches the bottom, so that when the sampling tube penetrates the sediment, the support frame 6 cannot achieve the buffering function or the effective buffering distance is shortened. The leg ballast lead 12 is provided at the bottom of the leg 62. Before the sampling operation, it can be flexibly selected whether to install it according to the actual sea conditions and the lowering speed, so as to further improve the stability of the sampler.

[0048] The working principle of the embodiment of the present invention is:

[0049] The visual multi-tube sampler can conduct deck video surveillance and interactive monitoring of underwater system operations. The sampler relies on gravity drive and damping piston cylinder buffer penetration technology to insert the multi-tube sampling tube into the sediment at a certain speed, and automatically completes the closure of the tube mouth during the lifting process to obtain the original state samples of the seabed sediment.

[0050] Before touching the bottom, the upper and lower cover linkage mechanisms of the collection head 5 are in a state of waiting to be triggered, and the upper and lower covers are opened;

[0051] After the support frame 6 touches the bottom, the collection frame 2 and the collection head 5 continue to move slowly downward and penetrate into the sediment under the action of the buffer piston;

[0052] The winch system reels in the cable and lifts it up, the support frame 6 remains stationary, the collection frame 2 and the collection head 5 move upward, the trigger switch is turned on, and the upper and lower cover components are automatically closed;

[0053] Continue to reel in the cable and lift it up. After the collection frame 2 reaches the limit position of the support frame 6, it drives the support frame 6 away from the seabed, and the sampling is completed.

[0054] The present invention is not limited to the above-mentioned embodiments. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
