Description

Technical Field

[0001] The invention relates to the technical field of seabed static detection structures, and more specifically, to a seabed static detection structure with automatic righting adjustment. Background Art

[0002] Seabed static penetration sounding is an important in-situ testing method. Since its invention in 1917, it has been widely used in the field of marine engineering surveys. Its advantage is that it can quickly and continuously obtain the physical and mechanical properties of seabed soil. It is widely used in the field of marine engineering and provides important data for geological surveys in marine engineering.

[0003] With the continuous development of seabed static detection technology, seabed detection equipment is also moving towards intelligence and automation.

[0004] In existing technologies, the righting and adjustment of seabed exploration equipment mostly relies on manual operation or simple mechanical structures, and lacks automated real-time monitoring and adjustment capabilities. For example, after entering the water, some seabed exploration equipment is prone to tilting due to the influence of water flow and seabed topography. Existing technologies are often unable to adjust the equipment posture in a timely manner. Usually, the exploration task needs to be completed through the positioning of the exploration vessel and manual adjustment of the equipment posture. This manual intervention method is not only inefficient, but also difficult to achieve high-precision righting and adjustment in complex seabed environments. Summary of the Invention

[0005] The purpose of the present invention is to provide a seabed static detection structure with automatic righting and adjustment, aiming to solve the problem of insufficient automation of righting and adjustment of seabed static detection structures in the prior art.

[0006] The present invention is achieved by: a self-righting and adjustable seabed static detection structure comprising a frame, wherein the frame is provided with a sounding rod and a driving structure for driving the sounding rod to move longitudinally; a hollowed-out enclosing frame is provided on the frame, the enclosing frame being arranged around the circumference of the frame to enclose a hollowed-out upper region;

[0007] The enclosure frame is provided with a plurality of peripheral airbags, which are evenly spaced along the circumference of the enclosure frame and arranged obliquely in the same direction; the top of the enclosure frame is provided with a horizontally arranged top airbag, which is in the shape of a flat plate;

[0008] The plurality of peripheral airbags and the top airbag are independently connected to the inflation and exhaust devices through air pipes. The frame is provided with a sensor for measuring the tilt angle of the frame. The sensor and the inflation and exhaust devices communicate with the controller respectively.

[0009] During the process of the frame in seawater, the sensor monitors the tilt angle data of the frame and feeds the tilt angle data back to the controller. The controller controls the inflation and deflation equipment to independently inflate or deflate multiple peripheral airbags and the top airbag according to the tilt angle data until the tilt angle of the frame is within the set angle range.

[0010] Furthermore, the frame is arranged in a hollow manner. The bottom of the frame is provided with a circular bottom peripheral ring. A plurality of bottom straight rods are arranged in a criss-cross manner in the peripheral ring, and a plurality of bottom holes are formed by enclosing between the plurality of bottom straight rods.

[0011] Furthermore, the top of the frame is provided with a circular top peripheral ring, and the top peripheral ring is located above the bottom peripheral ring; a plurality of peripheral straight rods are connected between the top peripheral ring and the bottom peripheral ring, and the plurality of peripheral straight rods are arranged in a circumferential manner along the top peripheral ring, connecting the top peripheral ring and the bottom peripheral ring into one body, and there are peripheral holes between adjacent peripheral straight rods.

[0012] Furthermore, a plurality of top straight rods are arranged in a criss-cross manner in the top peripheral ring, and a plurality of top holes are formed by enclosing between the plurality of top straight rods.

[0013] Furthermore, the bottom of the enclosure frame is docked with the top and bottom peripheral rings. The periphery of the enclosure frame has a plurality of inclined rods, and the plurality of inclined rods are arranged at intervals in a circumferential manner along the enclosure frame. The plurality of inclined rods enclose to form the upper region;

[0014] An outer peripheral empty area is formed between adjacent inclined rods, and the outer peripheral airbag is connected in the outer peripheral empty area. Along the upward extension direction of the enclosure frame from bottom to top, the inclined rods are arranged obliquely towards the upper region.

[0015] Furthermore, the top of the enclosure frame encloses to form a middle empty area, and the top airbag is movably arranged in the middle empty area; during the process of the enclosure frame automatically floating and sinking in seawater, the top airbag automatically swings up and down within a set angle range to adjust the swing angle of the enclosure frame.

[0016] Furthermore, a middle ring is formed on the periphery of the middle empty area, and the middle ring is arranged in a circumferential manner along the middle empty area; both ends of the middle part of the top airbag extend outwards respectively to have rotating shafts, and the two rotating shafts are respectively rotationally connected with the middle ring.

[0017] Further, there is an outer peripheral gap between the outer periphery of the top airbag and the middle ring, and the rotating shaft is arranged in the outer peripheral gap; a plurality of elastic bands are arranged in the outer peripheral gap, and the plurality of elastic bands are arranged at intervals along the circumferential direction of the top airbag; the outer ends of the elastic bands are connected to the middle ring, and the inner ends of the elastic bands are connected to the outer periphery of the top airbag;

[0019] Further, the top of the top airbag has a top surface, the bottom of the top airbag has a bottom surface, and the middle of the top airbag forms a central position; the top surface is recessed downward to form a plurality of inverted cone-shaped top grooves, the bottom surface is recessed upward to form a plurality of cone-shaped bottom grooves, and the plurality of top grooves and the plurality of bottom grooves are respectively arranged at intervals along the outer periphery of the central position.

[0020] Further, the central position is arranged to penetrate up and down to form a vertically penetrating through hole, the top of the through hole penetrates the top surface to form a top opening, and the bottom of the through hole penetrates the bottom surface to form a bottom opening; along the direction from the middle of the through hole to the top opening, the diameter of the through hole gradually increases, and along the direction from the middle of the through hole to the bottom opening, the diameter of the through hole gradually increases.

[0021] Compared with the prior art, the automatic self-righting and adjusting subsea static detection structure provided by the present invention sets a plurality of outer peripheral airbags and a top airbag on the frame, and uses sensors to monitor the inclination angle of the frame in real time, and feeds the monitoring data back to the controller. The controller independently inflates or deflates the airbags according to the inclination angle data, so as to realize the automatic self-righting of the frame;

[0022] Since the attitude of the subsea static detection structure can be automatically adjusted without manual intervention, it ensures that the frame always remains within the set inclination angle range, thereby providing a stable platform for the longitudinal movement of the sounding rod and improving the detection accuracy and operation efficiency;

[0023] In addition, the automatic self-righting adjustment of the subsea static detection structure can enhance the adaptability to complex subsea terrains and water flow conditions, reduce the risk of damage due to inclination or instability, and further improve the reliability and safety.

[0034] Refer to Figures 1-4 as shown, which is a preferred embodiment provided by the present invention.

[0035] An automatic self-righting and adjusting subsea static detection structure, including a frame body 100, in which a sounding rod 101 and a driving structure 102 for driving the sounding rod 101 to move longitudinally are provided; a surrounding frame 200 arranged in a hollow manner is provided on the frame body 100, the surrounding frame 200 is arranged in a circumferential direction around the frame body 100, and the surrounding frame 200 encloses an upper region arranged in a hollow manner;

[0036] A plurality of outer peripheral air bags 201 are provided on the surrounding frame 200, the plurality of outer peripheral air bags 201 are evenly spaced along the circumferential direction of the surrounding frame 200, and the plurality of outer peripheral air bags 201 are arranged obliquely in the same direction; a top air bag 300 arranged horizontally is provided at the top of the surrounding frame 200, and the top air bag 300 is in the shape of a flat plate;

[0037] The plurality of outer peripheral air bags 201 and the top air bag 300 are respectively independently connected to an air charging and pumping device through air pipes, a sensor for measuring the inclination angle of the frame body 100 is provided in the frame body 100, and the sensor and the air charging and pumping device are respectively in communication with a controller;

[0038] During the process of the frame body 100 in seawater, the sensor monitors the inclination angle data of the frame body 100 and feeds back the inclination angle data to the controller. The controller controls the air charging and pumping device to independently inflate or deflate the plurality of outer peripheral air bags 201 and the top air bag 300 according to the inclination angle data until the inclination angle of the frame body 100 is within the set angle range.

[0039] The above-provided automatic self-righting and adjusting subsea static detection structure realizes the automatic self-righting of the frame body 100 by arranging a plurality of outer peripheral air bags 201 and a top air bag 300 on the frame body 100, using the sensor to real-time monitor the inclination angle of the frame body 100, feeding back the monitoring data to the controller, and the controller independently inflating or deflating the air bags according to the inclination angle data;

[0040] Since this structure can automatically adjust the equipment posture without manual intervention, it ensures that the frame body 100 always remains within the set inclination angle range, thereby providing a stable platform for the longitudinal movement of the sounding rod 101 and improving the detection accuracy and operation efficiency;

[0041] In addition, this structure also enhances the adaptability of the equipment to complex subsea terrains and water flow conditions, reduces the risk of equipment damage due to inclination or instability, and further improves the reliability and safety of subsea static detection.

[0042] In this embodiment, the frame body 100 is arranged in a hollow manner, a circular bottom outer ring 103 is provided at the bottom of the frame body 100, a plurality of bottom straight rods 104 arranged vertically and horizontally are provided in the outer ring, and a plurality of bottom holes 105 are enclosed between the plurality of bottom straight rods 104.

[0043] With such a structure of the frame 100, the overall weight can be reduced, and its buoyancy performance in seawater can be enhanced. At the same time, the bottom hole 105 structure formed by the bottom outer peripheral ring 103 and the straight rods can effectively reduce the water flow resistance, improve the stability of the equipment in the seabed environment, and provide a basic support for subsequent uprighting adjustment.

[0044] In this embodiment, the top of the frame 100 is provided with a circular top outer peripheral ring 106, and the top outer peripheral ring 106 is located above the bottom outer peripheral ring 103; a plurality of outer peripheral straight rods 107 are connected between the top outer peripheral ring 106 and the bottom outer peripheral ring 103, and the plurality of outer peripheral straight rods 107 are arranged circumferentially around the top outer peripheral ring 106 to connect the top outer peripheral ring 106 and the bottom outer peripheral ring 103 into one body, and there are outer peripheral holes 108 between adjacent outer peripheral straight rods 107.

[0045] In this way, the top outer peripheral ring 106 and the bottom outer peripheral ring 103 are connected by the outer peripheral straight rods 107 to form a stable frame structure. The setting of the outer peripheral holes 108 further optimizes the water flow throughability, reduces the resistance of the equipment during the water entry process, enhances the overall structural strength of the frame 100, and provides a guarantee for the stable operation of the equipment.

[0046] In this embodiment, a plurality of top straight rods 109 arranged vertically and horizontally are provided in the top outer peripheral ring 106, and a plurality of top holes 110 are formed by enclosing between the plurality of top straight rods 109.

[0047] In this way, the structural layout of the frame 100 is further optimized, the top weight is reduced, and at the same time, the compressive performance of the top is enhanced, ensuring that the equipment can maintain structural stability in a complex seabed environment and providing a reliable structural basis for subsequent uprighting adjustment.

[0048] In this embodiment, the bottom of the enclosing frame 200 is docked with the top outer peripheral ring 106, and the outer periphery of the enclosing frame 200 has a plurality of inclined rods 202, and the plurality of inclined rods 202 are arranged at intervals circumferentially around the enclosing frame 200, and the plurality of inclined rods 202 enclose an upper region;

[0049] An outer peripheral empty area 203 is formed between adjacent inclined rods 202, and the outer peripheral airbag 201 is connected in the outer peripheral empty area 203. Along the upward extension direction of the enclosing frame 200, the inclined rods 202 are arranged obliquely towards the upper region.

[0050] Through the setting of the inclined rods 202, the outer peripheral airbag 201 can better adapt to the water flow direction. Through the inflation and deflation adjustment of the airbag, the inclined rods 202 can effectively guide the deformation direction of the airbag, thereby realizing the precise control of the inclination angle of the frame 100, solving the problem of insufficient automation of uprighting adjustment, and significantly improving the automatic uprighting ability of the equipment.

[0051] In this embodiment, the top of the enclosure frame 200 encloses to form a middle empty area, and the top airbag 300 is movably arranged in the middle empty area; during the process of the enclosure frame 200 automatically floating and sinking in seawater, the top airbag 300 automatically swings up and down within a set angle range to adjust the swing angle of the enclosure frame 200.

[0052] Through the movable arrangement and automatic swing function of the top airbag 300, the position of the enclosure frame 200 can be dynamically adjusted according to its floating and sinking state, further optimizing the attitude adjustment ability of the device, improving the adaptability and stability of the device under complex water flow conditions, and enhancing the flexibility of the upright adjustment.

[0053] In this embodiment, a middle ring 204 is formed on the outer periphery of the middle empty area, and the middle ring 204 is arranged along the circumferential direction of the middle empty area; both ends of the middle part of the top airbag 300 extend outwards respectively to form rotating shafts 301, and the two rotating shafts 301 are respectively rotationally connected to the middle ring 204.

[0054] Through the connection setting of the rotating shaft 301 and the middle ring 204, a stable mechanical support is provided for the dynamic adjustment of the top airbag 300, ensuring that the airbag can swing freely within the set range, and improving the attitude adjustment accuracy and reliability of the device.

[0056] When the outer periphery of the top airbag 300 is arranged flush with the middle ring 204, the elastic bands 303 are in a natural state, and when the top airbag 300 swings up and down relative to the middle ring 204, the elastic bands 303 are in a stretched state.

[0057] In this way, the elastic bands 303 can provide elastic buffering for the swing of the top airbag 300, absorb and release energy during the swing of the airbag, prevent the airbag from being damaged due to excessive swing, and at the same time, enhance the stability and reliability of the device in a complex environment.

[0059] In this way, the top groove 306 and the bottom groove 307 optimize the structure of the top airbag 300, enabling it to deform more uniformly during the inflation and deflation processes, improving the adjustment efficiency and response speed of the airbag, and further enhancing the automatic righting ability of the device.

[0060] In this embodiment, the center position penetrates vertically up and down to form a through hole that vertically penetrates up and down. The top of the through hole penetrates the top surface 304 to form a top opening 308, and the bottom of the through hole penetrates the bottom surface 305 to form a bottom opening 309; along the direction from the middle of the through hole to the top opening 308, the diameter of the through hole gradually increases, and along the direction from the middle of the through hole to the bottom opening 309, the diameter of the through hole gradually increases.

At the same time, the variable diameter design can better adapt to different air pressure conditions, enhancing the adaptability and stability of the device.

[0062] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
