TECHNICAL FIELD
[0001] The application belongs to the technical field of ocean observation platform, and particularly relates to an underwater mooring profile observation platform driven by upper sea current. BACKGROUND
[0002] With the urgent need of ocean resource development and the increasing in-depth study of ocean environment, it is particularly important to observe and investigate the ocean. The ocean observation objects mainly include ocean hydrology, meteorology, physics, chemistry, biology and other information elements. These observation elements have important roles and significance for ocean science research, seabed resource distribution exploration, weather forecast, fishery investigation, ocean engineering construction, navigation safety, and territorial defense. There are various methods to obtain ocean observation element data. With the development of science and technology and the gradual development of ocean observation towards deep sea, stereoscopic, unmanned and in-situ detection, etc.
[0003] Ocean information data is usually obtained by using observation tools and instrument equipment. The understanding and knowledge of the ocean are inseparable from long-term observation of the ocean. Therefore, whether the information data can be obtained for a long time is an important performance indicator for evaluating ocean observation equipment. Although the ocean observation tools such as surface research vessels and underwater manned carriers have the ability to carry out long-term and continuous ocean observation, the economy and safety limit their use. Unmanned underwater and surface carriers, buoys and other tools have become the main force of current ocean observation equipment. At present, the instrument equipment that can be used for relatively long-term and unmanned underwater observation at home and abroad mainly includes four types: autonomous underwater vehicle (AUV), profile observation buoy such as Argo buoy, underwater glider and submarine. The first three types can be used for observation in a large range of sea area, while the submarine is mainly used for in-situ observation in a specific sea area. One of the key factors that determines the observation time is the size of the power carried by the profile observation equipment and the energy consumption for movement. Under the same conditions of the power carried and the power consumption of the observation instrument, the less the electric energy consumed by the profile observation platform during movement, the longer the observation time. Compared with the autonomous underwater vehicle which completely relies on electric drive to realize movement, the underwater glider and the self-sinking and floating profile detection buoy mainly realize movement by changing the buoyancy, which has low energy consumption and greatly improves the observation time. However, the underwater glider and the self-sinking and floating profile detection buoy cannot plan the observation path, so the observation area of the underwater glider and the self-sinking and floating profile detection buoy has great randomness.
[0004] With the development of marine scientific investigation, engineering construction, resource exploitation and utilization, aquaculture activities to the deep sea and the need of national defense security, marine observation usually needs to be carried out for specific areas, and long-term in-situ monitoring of the ocean becomes an important direction of marine observation. As an important technical means of in-situ observation, the early mooring is usually laid along the cable to obtain the data of marine observation elements by a number of sensors in series. In order to reduce the number of sensors and realize the observation of any point in the full water depth, Massachusetts Institute of Technology (MIT) proposed a method of profiling observation along the cable in the 1980s. The method realizes the up and down movement along the cable of the mooring by changing the buoyancy, which is the earliest research report about profiling observation along the cable. Since then, according to the different sources of moving power, there are three kinds of profiling observation platforms moving along the cable, namely motor-driven, buoyancy-driven and wave energy-driven. The former two need to consume electric energy, which affects the observation time. The latter cannot realize profiling observation in the polar ice ocean environment by using wave energy. In summary, so far, the research and technology of long-term in-situ continuous profiling observation in global sea areas are still in the blank stage. It has important theoretical significance and application innovation value to explore and research in this field. SUMMARY

[0042] In order to facilitate the understanding of the present application, the present application will be described in more detail below in conjunction with the drawings and specific embodiments. However, the present application can be implemented in many different forms, and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present application more thorough and comprehensive.
[0043] This invention provides an underwater moored profiling platform driven by upper ocean currents, as shown in Figure 1. The platform comprises an upper buoy 101, an upper mooring line 102, a main buoy 103, an impeller mechanism 104, a moving platform 105, a lower buoy 106, a lower mooring line 107, and an anchoring base 109. The upper mooring line 102 and the lower mooring line 107 are two independent mooring lines. The upper mooring line 102 connects the main buoy 103 to the upper buoy 101, and the lower mooring line 107 connects the main buoy 106 to the lower buoy 106. The impeller mechanism 104 is located inside the main buoy at its upper end and below the main buoy at its lower end. The moving platform 105 is mounted on the lower mooring line 107. The anchoring base 109 has a pulley block 108, and the lower mooring line 107 can move along the pulley block 108 after passing through it. The lower float 106 is located on one side of the anchoring base, while the upper float 101, main float 103, impeller mechanism 104, and moving platform 105 are all located on the opposite side of the lower float 106. The sum of the net buoyancy of the main float 103 and the upper float 101 is greater than the net buoyancy of the lower float 106, and the net buoyancy of the lower float 106 is greater than the net buoyancy of the main float 103.
[0044] The main float 103 is equipped with a first reversing mechanism 110, a retrieval and release mechanism 120, and a clutch mechanism 130. The retrieval and release mechanism 120 and the clutch mechanism 130 are respectively installed inside the main float 103 via fixed brackets 140. The lower end of the upper mooring line 102 is connected to the retrieval and release mechanism 120, which is used to retrieve or release the upper mooring line 102 and the upper float 101. The impeller mechanism 104 converts the captured ocean current into mechanical energy, which is transmitted to the retrieval and release mechanism 120 via a worm gear mechanism and the clutch mechanism 130. The first reversing mechanism 110 controls the connection and disconnection of the clutch mechanism 130 and the retrieval and release mechanism 120, thereby controlling the retrieval and release mechanism 120 to switch between retrieval and release states.
[0045] like Figure 3 As shown, the impeller mechanism 104 consists of an impeller 1041 and a hollow shaft 1042. A worm gear 1043 is provided at the top of the hollow shaft 1042. The upper part of the hollow shaft 1042 is located inside the main float and is connected to the bottom of the main float. The upper end of the lower mooring cable 107 passes through the interior of the hollow shaft 1042 and is supported at the top of the hollow shaft 1042 by a pressure sleeve.
[0046] like Figure 4 , Figure 5 As shown, the first reversing mechanism 110 includes an upper contact rod 1101, a lower contact rod 1102, a fixed cone 1103, a linkage cone 1104, a first baffle 1105, a second baffle 1106, a wedge-shaped slider 1107, a spring a 1108, a spring b 1109, and a spring c 1110. Among them, as... Figure 8As shown, the upper touch rod 1101 is in inverted "Y" shape structure, and its lower end has a hole cavity structure, in which a wedge-shaped slider 1107 is connected by a c spring 1110, and the wedge-shaped slider 1107 can move in the hole cavity. The fixed cone 1103 is located on the central axis of the lower part of the inverted "Y" shape structure. The fixed cone 1103 is fixed on the main float by an upper support frame 1111. The upper touch rod is also provided with a first baffle 1105, which is fixedly connected with the upper support frame 1111, and an a spring 1108 is arranged between the inverted "Y" shape structure of the upper touch rod and the first baffle 1105. A roller 1113 is further arranged outside the lower end of the inverted "Y" shape structure of the upper touch rod.
[0047] As shown in Figure 4 and Figure 6 The lower touch rod 1102 is fixed with the linkage cone 1104, and the second baffle 1106 is connected with the lower support frame 1112 and fixed in the main float, and a b spring 1109 is arranged between the second baffle 1106 and the linkage cone 1104. The lower touch rod 1102 can move up and down relative to the second baffle 1106.
[0048] The upper touch rod 1101 is provided with a first trigger mechanism composed of a swivel ring group 150 and a pressing plate 160. The swivel ring group 150 is located on the upper end of the cable 102. One end of the pressing plate 160 is fixed on the top of the upper touch rod, and the other end is provided with a through hole, and the upper end of the cable 102 passes through the through hole. The pressing plate 160 is located above the main float. When the upper end of the cable 102 is retracted, the swivel ring group 150 moves downward with the upper end of the cable 102, and when the swivel ring group 150 contacts and moves downward with the pressing plate 160, the swivel ring group 150 pushes the pressing plate 160 downward, thereby triggering the lower movement of the upper touch rod 1101.
[0049] The lower touch rod 1102 is provided with a second trigger mechanism composed of a stop rod 170 and a conical stop block 180. The stop rod 170 is connected to the upper part of the lower touch rod 1102, and the conical stop block 180 is fixed at the end of the upper end of the cable 102 and located below the stop rod 170, which can be blocked by the stop rod 170. When the upper end of the cable 102 is about to be completely released, the conical stop block 180 will contact the stop rod 170, and with the continuous release of the upper end of the cable, the conical stop block 180 pushes the stop rod 170 upward, thereby triggering the upward movement of the lower touch rod 1102.
[0050] When the upper touch rod of the first reversing mechanism is triggered to move downward, the wedge-shaped slider 1107 will pass over the fixed cone 1103, so that the upper touch rod 1101 is located at the bottom surface position of the cone 1103 and remains stationary, as shown in Figure 7 When the lower touch rod 1102 of the first reversing mechanism is triggered to move upward, the conical surface of the linkage cone 1104 connected with the lower touch rod 1102 contacts the wedge surface of the wedge-shaped slider 1103, as shown in Figure 7As shown in (b), as the lower contact rod 1102 continues to move upward, the two large bottom surfaces of the linkage cone 1104 and the fixed cone 1103 come into contact. At this time, the wedge-shaped slider 1107 disengages from the contact between the linkage cone 1104 and the fixed cone 1103, and the upper contact rod 1101 moves upward under the action of spring a 1108, completing the reset. At this time, the lower contact rod 1102 loses the upward force and moves downward under the action of spring b 1109, completing the reset, as shown in (b). Figure 7 As shown in (c).
[0051] During the process of retrieving the upper mooring line, i.e., retrieving the upper float, the first reversing mechanism is located in... Figure 7 The workstation shown in (c) is in the middle. During the process of releasing the upper mooring line, i.e., the upper float, to float freely upwards, the first reversing mechanism is located at... Figure 7 The workstation shown in (a) is shown in the middle.
[0052] like Figure 9 As shown, the retrieval and release mechanism includes a cable reel 1201 and a spool 1202; both sides of the spool 1202 are fixed to the main buoy body by brackets. A second bevel gear 1203 is installed at one end of the spool 1202. The lower end of the upper tether 102 is fixed to the cable reel 1201. When the cable reel 1201 rotates with the spool 1202, the upper tether 102 can be retrieved or released.
[0053] like Figure 10 and Figure 11 As shown, the clutch mechanism mainly includes a first bevel gear 1301, a second bevel gear 1203, a key shaft 1303, a sliding sleeve 1304, a spring 1305, a wedge block 1306, a retaining ring 1307, and a retaining ring 1308. The retaining ring 1308 is fixed to the main float body by a bracket; the sliding sleeve 1304 passes through the retaining ring 1308 and is keyed to the key shaft 1303, and the rotation of the key shaft is transmitted to the sliding sleeve via the key. One end of the sliding sleeve 1304 has an annular groove, and the retaining ring 1307, after being connected to the wedge block 1306, is installed in the annular groove of the sliding sleeve 1304, allowing the retaining ring to rotate relative to the sliding sleeve; the other end of the sliding sleeve 1304 is fixedly connected to the first bevel gear 1301; the spring 1305 is sleeved on the sliding sleeve between the retaining ring 1308 and the first bevel gear 1301. The wedge block 1306 cooperates with the roller 1113 on the upper contact rod 1101. The worm gear 1302 is mounted on one end of the key shaft 1303. The worm gear 1302 meshes with the worm 1043 to transmit the mechanical energy of the ocean current captured by the impeller mechanism to the clutch mechanism.
[0054] When the roller 1113 is driven by the upper touch rod to move down along the slope surface of the inclined block 1306, the clamping ring 1307 is pushed by the inclined block 1306 to move to the direction of the worm wheel 1302, thereby driving the sliding sleeve 1304 and the first bevel gear 1301 to move along the key shaft 1303, at this time, the spring 1305 is compressed, the first bevel gear 1301 and the second bevel gear 1203 are disconnected. When the roller 1113 is driven by the upper touch rod to move up along the slope surface of the inclined block and is separated from the inclined block, under the elastic force of the spring 1303, the sliding sleeve 1304 and the first bevel gear 1301 are reset, the first bevel gear 1301 is reconnected with the second bevel gear 1203.
[0055] In the present application, the retraction / release principle and process of the upper end float are described in detail as follows: the impeller mechanism rotates under the driving action of the sea current, the energy is transmitted to the key shaft through the worm and the worm wheel, the key shaft drives the sliding sleeve to rotate, thereby driving the second bevel gear to rotate through the first bevel gear, and driving the cable reel to rotate to retract the upper end cable; in the process of retraction, when the swivel group contacts the pressing plate, the upper touch rod is triggered to move down, the roller is driven by the upper touch rod to move down along the inclined block, the inclined block drives the clamping ring and the sliding sleeve to move to the direction of the worm wheel, so that the first bevel gear is disconnected with the second bevel gear; at this time, the reel loses power, under the buoyancy of the upper end float, the reel rotates reversely to release the upper end cable. When the upper end cable is about to be completely released, the conical stop block contacts the stop rod to trigger the lower touch rod to move up, when the two large bottom surfaces of the linkage conical surface and the fixed conical surface are in contact, the upper touch rod moves up under the action of the spring a, after resetting, the roller is separated from the inclined block, the sliding sleeve and the first bevel gear are reset under the action of the spring, the first bevel gear and the second bevel gear are reconnected, and the cable reel starts to rotate to wind the upper end cable again, entering the next retraction-release cycle.
[0056] In the present application, the sea current drives the impeller system to drive the retraction / release mechanism to retract or release the upper end float, in the process of retracting the upper end float, as shown in (a) of Figure 12 , the upper and lower end cables are in tension. When the upper end float is released, as shown in (b) of Figure 12 , the tension of the upper end cable is zero, the lower end float drives the main float to move down until the tension of the upper end cable is restored, at this time, since the sum of the net buoyancy of the main float and the upper end float is greater than the net buoyancy of the lower end float, the main float starts to move up. With the continuous alternation of the retraction and release of the upper end float, the main float also performs a vertical heaving motion due to the change of the tension of the upper and lower end cables. The retraction / release mechanism changes the tension of the lower end cable by pulling the tensioned upper end cable to retract the upper end float and freely rising to release the upper end float, thereby realizing the vertical oscillation of the lower end cable. When the upper end float freely rises, the lower end cable moves downward, and when the upper end float is retracted and lowered, the lower end cable moves upward.
[0057] As shown in Figure 13As shown, the mobile platform 105 is a carrier for installing the profile observation instrument, and the carrier has a total of 2 half-cylindrical shell structures, which are connected by bolts into a Figure 1 As shown, the mobile platform 105 is a carrier for installing the profile observation instrument, and the carrier has a total of 2 half-cylindrical shell structures, which are connected by bolts into a
[0058] As shown, the mobile platform 105 is a carrier for installing the profile observation instrument, and the carrier has a total of 2 half-cylindrical shell structures, which are connected by bolts into a Figure 14 As shown, the single-direction moving mechanism 200 includes two symmetrically arranged upper and lower L-shaped grooves, two rollers and two L-shaped limit rods. The upper L-shaped groove contains a first wedge-shaped groove 2001, and the lower L-shaped groove contains a second wedge-shaped groove 2002. The wide end of the first wedge-shaped groove 2001 is downward, and the wide end of the second wedge-shaped groove 2002 is upward. The positions of the first wedge-shaped groove 2001 and the second wedge-shaped groove 2002 are opposite, and the side surfaces of the wedge-shaped grooves are open. The bottom of the first wedge-shaped groove 2001 is provided with a d spring 2008. The first roller 2003 is arranged in the first wedge-shaped groove 2001, and the second roller 2004 is arranged in the second wedge-shaped groove 2002. The first limit rod 2005 is arranged in the upper L-shaped groove, and the second limit rod 2006 is arranged in the lower L-shaped groove. The first limit rod 2005 and the second limit rod are fixedly connected with the upper trigger rod, and can move up and down in the L-shaped groove under the driving of the upper trigger rod.
[0059] The upper and lower ends of the semi-cylindrical axis position are provided with a guide wheel set 2007. The lower end cable 107 passes through the guide wheel set 2007, and is located at the opening of the wedge-shaped groove side and can be in contact with the roller. As shown in FIG. 15(a), when the lower end cable moves downward, the second roller 2004 under the one-way moving mechanism rolls to the narrow end of the second wedge-shaped groove 2002 under the drive of the lower end cable 107, thereby realizing the downward movement of the moving platform following the lower end cable 107. The first roller 2003 can only be located at the wide end of the first wedge-shaped groove 2001 due to the limiting action of the first limiting rod 2005, and cannot be in contact with the lower end cable, so as to not limit the relative movement of the carrier and the lower end cable. In this way, under the wedging action of the second roller 2004, the moving platform descends with the downward movement of the lower end cable. When the moving platform descends to the lowest point, the swivel group at the lower end of the lower end cable presses the pressing plate connected with the lower contact rod, triggering the action of the second reversing mechanism (the action process of the second reversing mechanism is referred to the first reversing mechanism), and the position of each component of the one-way moving mechanism changes from FIG. 15(a) to FIG. 15(b).
[0060] As shown in FIG. 15(b), when the lower end cable 107 moves upward, the second roller 2004 of the one-way moving mechanism can only be located at the wide end of the second wedge-shaped groove 2002 due to the limiting action of the second limiting rod 2006; and the first roller 2003 is not limited by the first limiting rod 2005, and is pushed to the narrow end of the first wedge-shaped groove 2001 under the action of the spring 2008. In this way, under the wedging action of the first roller 2003, the moving platform rises with the upward movement of the lower end cable. When the moving platform rises to the highest point, the swivel group above the lower end cable presses the pressing plate connected with the upper contact rod, triggering the action of the reversing mechanism, and the position of each component of the one-way moving mechanism changes from FIG. 15(b) to FIG. 15(a).
[0061] In the present application, when the main float oscillates, the moving platform can follow the oscillation of the main float to complete the profile movement along the lower end cable through the one-way moving mechanism. The upper end and the lower end of the lower end cable are provided with two swivel groups, which are used to release the cable torsion on one hand, and to trigger the reversing mechanism to complete the change of the moving direction of the moving platform and the upper end float and to constrain the movement range of the cable on the other hand. The moving platform is between the two swivel groups, and moves upward with the upward movement of the lower end cable, or moves downward with the downward movement of the lower end cable, so as to realize the following of the moving platform to the oscillation of the lower end cable, complete the intermittent descent or ascent, and complete the automatic conversion of the descending-ascending process of the moving platform at the upper and lower end positions of the profile observation.
