Description

Technical Field

[0001] The present invention relates to the technical field of deep-sea observation platforms, and in particular to a deep-sea lifting platform driven jointly by eccentric power and torque return. Background Art

[0002] In deep-sea exploration and scientific research, it is necessary to obtain near-bottom profile observation data, which requires the use of environmental sensors, cameras, and in-situ analysis systems and other instruments and equipment to perform reciprocating profile measurements on a section of water column. These observation instruments can only collect the data required for scientific research if they are equipped with a mobile platform with lifting functions. The lifting of the platform can take many forms, such as completing the lifting by changing the overall buoyancy, directly driving the lifting by the form of a winch cable, and driving by the friction force of the roller cable. However, in the deep seabed, an environment that is difficult for humans to reach, to obtain time-series scientific observation data, platforms are usually deployed on the seabed for a long time and run unmanned and automatically. Working for a long time under limited electricity and obtaining more observation data are urgent needs for deep-sea scientific research. In addition, the increase in research needs means that more and larger observation equipment needs to be deployed, and the increase in the size of the platform means that the buoyancy or resistance generated underwater increases, which puts a higher test on designs such as power consumption and structural stability.

[0003] In the prior art, the invention patent with publication number CN114212191A discloses a real-time data transmission device for an underwater buoy, in which an underwater winch and a main buoy audio machine are installed and fixed on the main buoy of the underwater buoy, and the underwater winch is controlled by the main control machine of the underwater buoy; the lifting platform audio machine, controller, sensor and satellite communication machine are installed on the lifting platform; the lifting platform is connected to the underwater winch through a mooring cable; this invention mainly completes the lifting and lowering of the communication probe by winch drive, but can only complete data observation at a fixed depth, which has limitations.

[0004] The patent with publication number CN102167136A discloses a marine lifting buoy system, in which the buoy is connected to the underwater winch through a communication mooring cable; multiple profile measurement instruments are evenly spaced near the buoy on the communication mooring cable between the buoy and the underwater winch. This method can achieve dynamic measurement, but it requires the installation of multiple sensors of the same type, which increases the cost.

[0005] The patent with publication number CN109733568A discloses a cable-tethered underwater lifting platform, which belongs to the field of underwater observation technology, and includes a platform component, a moving component that can be lifted and lowered along the cable, and a driving component that can drive the moving component to be lifted and lowered along the cable, and the platform component is rotatably connected to the moving component. It has the advantages of long travel within the battery capacity cycle, stable data collection, and stable lifting speed. However, this cable-tethered underwater problem will have a driving hidden danger, that is, the friction failure between the platform's driving wheel and the cable will cause the platform to be unable to complete the lifting normally.

[0006] The patent with the publication number of patent CN109835438A discloses a lifting submerged buoy device. It includes a communication buoy, a submerged buoy system and an anchor seat. The core driving mode of the submerged buoy system is winch drive, and the underwater winch includes a Caselaf cable, a motor, a winch counterweight, and a capstan. The motor is connected to the capstan, and the rotation of the motor drives the winch to rotate; the capstan is composed of two areas with different radii. The winch counterweight is connected to the end of a Caselaf cable with a small radius on the winch, and it sinks freely due to gravity. The communication buoy is connected to the end of another Caselaf cable with a large radius on the winch, and it naturally floats up due to buoyancy. The communication buoy is controlled to move back and forth between the sea level and the submerged buoy by the way of collecting and releasing the cable by the underwater winch. However, the structure described in this invention has risks when working. The counterweight on the submerged buoy will be entangled with the main cable under the action of the water flow, causing the entire submerged buoy system to fail to work.

[0007] The patent invention with publication number CN107585263A provides a locatable self-sinking and floating deep-sea moored detection platform, which includes a satellite antenna, a payload cabin, a hydraulic control cabin, a variable buoyancy cabin, an anchor chain cabin and a bottom anchor. The buoyancy change of the platform is controlled by a hydraulic system to achieve platform lifting. This technical solution can measure the positioning information of marine resources after accurately obtaining the location information of the measuring point. The variable buoyancy driving method can change the buoyancy to a limited extent, which will limit the load range of the lifting platform. And it is easy to float around under the influence of water flow.

[0008] In summary, the current deep-sea lifting platform has the following disadvantages:

[0009] 1. The lifting is driven by changing the buoyancy, and the power generated is too small. For large buoyancy equipment, the time period for changing the buoyancy is very long, and the actual submerged buoy cannot meet the lifting speed requirements, and the speed controllability is poor.

[0010] 2. The roller cable climbing method relies on friction force to drive. Long-term lifting and lowering work in deep-sea environment will cause too much wear and tear, which may easily lead to the failure of the friction force between the cable and the roller, affecting the normal lifting and lowering of the equipment.

[0011] 3. Lifting a device with large buoyancy by driving the winch cable requires a large torque output, which increases energy consumption. For the lifting of neutral buoyancy equipment, the equipment will float unsteadily during the lifting, and the winch is difficult to control.

[0012] Based on the above technical problems, the present invention provides a deep-sea lifting platform driven by a combination of eccentric power and torque return. Summary of the invention

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Reference Figure 1-5 The present invention provides a deep-sea lifting platform driven by eccentric power and torque return, comprising:

[0039] The floating platform 1 is suspended in the water;

[0040] Anchor block 3, anchor block 3 sinks to the seabed;

[0041] The lifting and carrying vehicle 2 includes a platform frame 6, on which a drum 5 is arranged, and the drum 5 is installed on the platform frame 6 through a motion auxiliary component 11. The drum 5 includes two coaxially connected reels, and the two reels are respectively wound with a first cable 4 and a second cable 13. One end of the first cable 4 is fixedly connected to the floating platform 1, and one end of the second cable 13 is fixedly connected to the anchor block 3. A rotation drive module 9 is installed on one side of the drum 5;

[0042] Among them, two sets of guide components 8 are installed on the platform frame 6, and the first cable 4 and the second cable 13 pass through the two sets of guide components 8 and are fixedly connected to the floating platform 1 and the anchor block 3 respectively. The guide components 8 are used to guide the first cable 4 and the second cable 13 so that the first cable 4 and the second cable 13 are located in the same plane.

[0043] When the present invention is working, the data acquisition instrument is carried by the lifting vehicle 2 to complete the fixed-point profile monitoring at the specified depth in the deep sea. According to the depth requirement, the rotation drive module 9 is started to drive the drum 5 to rotate. When it is necessary to rise, the rotation drive module 9 rotates in the opposite direction, and the first cable 4 connected to the floating platform 1 is used for cable winding, and the second cable 13 connected to the anchor block 3 is used for cable release. When the lifting vehicle 2 needs to descend, the first cable 4 is used for cable release, and the second cable 13 is used for cable winding.

[0044] The present invention is based on the principle of moment balance of a single system structure and performs buoyancy balancing to balance the moment of the cable on the drum 5. In this way, the small torque of the eccentric motor of the driving module can be transmitted to the eccentric counterweight steel ring, and the counterweight drives the drum 5 to rotate through torque return, thereby moving the lifting and carrying platform, thereby reducing the energy consumption of the system operation.

[0045] A further optimized solution is that the winding assembly includes a bidirectional screw rod 10 horizontally fixedly connected to the platform frame 6, the bidirectional screw rod 10 passes through the reel 5 and is coaxially arranged with the reel 5, a screw nut 12 is connected to one end of the reel 5, and the screw nut 12 and the bidirectional screw rod 10 are matched in bidirectional sliding manner through balls.

[0046] The reel 5 is made into a two-in-one cable arrangement and cable winding function, avoiding the use of two sets of cable guide mechanisms, simplifying the structure while improving the efficiency and reliability of cable winding. The function of the motion auxiliary component 11 avoids the risk of excessive load caused by the two-way screw 10 acting alone on the reel 5 in the air, and on the other hand, it also assists the reel 5 to perform axial movement under the action of the two-way screw 10.

[0047] A further optimized solution is that a motion auxiliary component 11 is symmetrically fixedly connected to the platform frame 6, and the motion auxiliary component 11 includes a support rod 111, a slide rail 112, and a first bearing 113. The support rod 111 is connected to the platform frame 6 through the slide rail 112, and the reel 5 is located between the support rods 111. The support rod 111 is vertically arranged with the bidirectional lead screw 10, and a first bearing 113 is installed on the support rod 111 at a coaxial position with the lead screw nut 12, and the lead screw nut 12 is fixed on the inner ring bearing of the first bearing 113.

[0048] A further optimized solution is that the rotating drive module 9 includes a pressure-resistant chamber 901, which is fixed on the end face of the reel 5. The pressure-resistant chamber 901 is a ring-shaped structure. An eccentric cylindrical cabin is provided on one side of the pressure-resistant chamber 901. A motor 907 is fixedly connected to the eccentric cylindrical cabin. The output shaft of the motor 907 is fixedly connected to a driving gear 902. A steel swing ring is rotatably connected to the pressure-resistant chamber 901. A tooth groove is provided on the inner wall of the steel swing ring. The driving gear 902 is meshed with the tooth groove of the steel swing ring. A counterweight 905 is fixedly connected to the steel swing ring. The eccentric cylindrical cabin is embedded in the reel 5.

[0049] A further optimized solution is that three groups of eccentric grooves 7 are opened on the side of the reel 5 close to the pressure-resistant chamber 901, the axes of the eccentric grooves 7 are parallel to the axis of the reel 5, and the axes of the three groups of eccentric grooves 7 are arranged in a circular array with the axis of the reel 5 as the center, the eccentric cylindrical cabin body is fixed in one of the eccentric grooves 7, and batteries are fixedly connected to the other two eccentric grooves 7, and the batteries are electrically connected to the motor 907.

[0050] A further optimization scheme is that a plurality of second bearings 906 are coaxially arranged in the pressure-resistant chamber 901, and the second bearings 906 are ball bearings. A plurality of support columns 903 are fixedly connected axially at equal intervals around the axis in the pressure-resistant chamber 901, and the ball bearings are mounted on the support columns 903, and the ball bearings cooperate with the inner wall support of the steel swing ring.

[0051] The driving mode of the traditional underwater winch is that the central rotating shaft of the drum 5 is connected to the output shaft of the motor 907. This structural mode requires an electric slip ring and a rotary seal. The slip ring can continuously supply power to the rotating parts, so that it is not bound by the power line during the rotation process, and the work is more flexible and high-energy. The rotary seal is also required to ensure the sealing when working underwater. In addition, the output of the central axis motor 907 may encounter the risk of overload. Based on this, this embodiment adopts a new driving concept. The motor 907 drives the driving gear 902 to rotate. In theory, a planetary gear structure is formed between the driving gear 902 and the steel swing ring, which will synchronously drive the steel swing ring to rotate. Therefore, a counterweight block 905 is set on the steel swing ring. Through the torque return resistance provided by the counterweight block 905, the counterweight block 905 remains unchanged at the nearly six o'clock position and remains stationary. In this way, the DC motor 907, the pressure-resistant chamber 901 and the drum 5 will rotate around the relatively stationary steel ring, and the diameter of its running track is the difference between the inner diameter of the steel swing ring and the diameter of the driving gear 902. And it is coaxial with the steel swing ring.

[0052] The integrated design of the motor 907 and the power supply with the drum 5 of the lifting vehicle 2 enables the motor 907, the battery and the entire drum 5 to simultaneously perform self-rotational axial motion. This design avoids the use of electric slip rings and improves work safety and reliability in deep-sea environments.

[0053] The use of the pressure-resistant chamber 901 allows the entire drive module to form a complete sealing structure, thereby improving the safety of the long-term operation of the lifting and carrying vehicle 2 in a deep-sea environment.

[0054] refer to Figure 4 Although the combination of the driving motor 907 and the steel swing ring provides torque by the rotation of the motor 907, the real driving torque of the entire driving module and the reel 5 comes from the counter-torque provided by the counterweight block 905 on the steel swing ring. Since the action of force is mutual, the force generated by the contact between the driving gear 902 and the inner teeth of the steel ring is a set of interactive forces, but the counterweight block 905 has a longer lever arm, so it can generate a larger torque acting on the entire reel 5.

[0055] Taking the counterclockwise direction of the torque generated by the steel swing ring as the positive direction, the output torque of the rotating pinion is m1=F1r1. When the eccentric weight is lifted, the tangential component of gravity on the center of the reel 5 is G1, and the torque generated is M=G1R. Since the reel 5 has the degree of freedom of rotation, the eccentric weight provides a torque for the rotation of the reel 5 while returning to the center. Therefore, when the counterweight 905 generates a large torque M, the small torque of the motor 907 is transmitted to the large torque M generated by the counterweight 905 as the driving torque for the motor 907 itself and the reel 5 to rotate.

[0056] When the load torque is too large, this structural method can play a buffering role; when the cable connecting the floating platform 1 is subjected to tension, if the motor 907 is in a non-working braking state at this time, a large torque will be generated to force the drive gear 902 output by the motor 907 to drive the steel pendulum ring to rotate. When the counterweight block 905 goes around the top 12 o'clock direction from the six o'clock direction of the bottom of the steel pendulum ring, it falls back to the bottom again and the cycle is repeated. This buffering method can prevent the motor 907 from continuously receiving excessive load caused by large resistance torque during non-working braking, thereby playing a protective role.

[0057] In a further optimized solution, the winding directions of the first cable 4 and the second cable 13 are opposite. The first cable 4 and the second cable 13 are wound in opposite directions, so that one of the first cable 4 and the second cable 13 can be wound up and the other released under the action of the drum 5.

[0058] In a further optimized solution, the guide assembly includes guide wheels 8, and two groups of guide wheels 8 are arranged on the platform frame 6. The first cable 4 passes through the two groups of guide wheels 8 and is fixedly connected to the floating platform 1; the second cable 13 is fixedly connected to the corresponding anchor block 3 through another group of guide assemblies. The two groups of guide wheels 8 can be arranged so that the first cable 4 and the second cable 13 are in the same vertical horizontal plane, so that the two cables form an action force and a reaction force, and ensure the stability of the force during the lifting process.

[0059] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0060] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
