Description

Technical Field

[0001] The present invention relates to the technical field of ocean buoys, and in particular to a portable buoy for ocean observation. Background Art

[0002] Marine ecological monitoring buoys monitor the marine environment. These buoys are typically anchored at sea, forming a network of automated marine hydrological and meteorological observation stations. These buoys can continuously collect long-term marine hydrological and meteorological data required for marine scientific research, offshore oil and gas development, port construction, and national defense development. These buoys are particularly capable of collecting data on adverse weather and sea conditions that are difficult to collect using survey vessels.

[0003] Patent application number 202020865082.7 proposes a portable buoy for ocean observation, which uses an exhaust fan inside the buoy shell to blow air into the airbag to expand it, and the buoyancy generated by seawater offsets the gravity of the cement sinker. Ocean observers can drive a small boat to pull the buoy shell to a new location. This structure does not require financial resources and a lot of time to prepare for the migration of the buoy. However, in this device, the airbag is always soaked in seawater. After a long period of seawater erosion, the airbag is easily broken and loses its effectiveness, thereby losing the effect of driving the cement sinker to float and facilitate the migration of the device to a new location. For this reason, we propose a portable buoy for ocean observation. Summary of the Invention

[0004] The present invention proposes a removable buoy for ocean observation, which solves the problem in the existing buoy device proposed in the background art that the airbag is always soaked in seawater. After a long period of seawater erosion, the airbag is easily broken and loses its effect, thereby losing the effect of driving the cement sinker to float and facilitate the migration of the device to a new location.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A portable buoy for ocean observation comprises a buoy shell with a float at the bottom end, a signal antenna installed at the top end of the buoy shell, auxiliary cabins hinged at the bottom ends of the three side walls of the buoy shell, and a telescopic connection piece installed between the auxiliary cabin and the buoy shell, a buoyancy lifting mechanism movably installed on the other three side walls of the buoy shell, the buoyancy lifting mechanism and the auxiliary cabin are spaced apart, the bottom end of the buoyancy lifting mechanism is connected to a connecting frame located below the buoy shell, and the buoyancy lifting mechanism is provided with an inflatable airbag that is movably connected to the connecting frame after inflation, and the bottom end of the connecting frame is fixed with a gravity block by an anchor chain.

[0007] Preferably, the buoyancy lifting mechanism includes a protective shell movably mounted on the outer side wall of the buoy shell, a motor 1 is mounted on the outer side of the protective shell, the output shaft of the motor 1 is connected to a driving roller rotatably connected to the inside of the buoy shell, driven rollers are mounted at the three corners of the connecting frame, an annular connecting belt is connected between the driving roller and the driven roller, and an inflatable airbag is mounted on the annular connecting belt through a connecting block;

[0008] A rope-loosening prevention mechanism is also installed between the buoyancy lifting mechanism and the buoy housing.

[0009] Furthermore, the cross-section of the connecting frame is triangular, and the bottom end of the connecting frame at the corner is rotatably connected to a driven roller through an extended mounting bracket, and three corresponding through-limiting holes are opened on the connecting frame. One side of the annular connecting belt is located outside the connecting frame, and the other side of the annular connecting belt and the connecting block and the inflatable airbag thereon slide through the through-limiting holes. The connecting block and the inflatable airbag are initially located inside the protective shell. When the device needs to move, the connecting block and the inflatable airbag move through the through-limiting holes to the bottom of the connecting frame, and then the inflatable airbag is inflated and limited to the bottom of the connecting frame to generate buoyancy.

[0010] Furthermore, a liquid pump and a detection chamber are installed inside the auxiliary cabin, and the two ends of the detection chamber are respectively connected to a water inlet pipe and a drain pipe. The liquid pump is installed on the water inlet pipe, and a detection probe is installed on the side wall of the detection chamber. A hydrological detection sensor group is located inside the detection chamber.

[0011] It is worth noting that one end of the water inlet pipe and the drain pipe both extend to the outside of the auxiliary cabin, and the drain pipe is located below the inspection cabin when the auxiliary cabin is in a vertical state. When the auxiliary cabin is in a vertical state and the inspection is completed, the water inside the inspection cabin automatically flows out through the drain pipe at the bottom under the action of gravity.

[0012] Furthermore, the anti-rope loosening mechanism includes a connecting rope, a pulley and a counterweight block located inside the buoy shell. A plurality of mounting holes are opened at the top of the side wall of the buoy shell. A pulley is rotatably connected in the mounting hole, and a connecting rope is slidably connected to the pulley. One end of the connecting rope is fixedly connected to the counterweight block, and the other end of the connecting rope is fixedly connected to the buoyancy lifting mechanism.

[0013] It is worth noting that corresponding tracks are installed on the inner and outer walls of the buoy shell, and the counterweight block and the buoyancy lifting mechanism are slidably connected to the track through sliding blocks. When the pulling force of the gravity block on the buoyancy lifting mechanism is reduced, the counterweight block drives the buoyancy lifting mechanism to move upward through its own gravity.

[0014] Furthermore, the telescopic connection includes a second motor, and three slide grooves corresponding to the auxiliary cabin are opened on the outer wall of the buoy shell. The output shaft of the second motor is connected to a threaded rod rotating inside the slide groove, and the threaded rod is threadedly connected to a slider slidingly connected in the slide groove, and a transmission rod is hinged between the slider and the corresponding auxiliary cabin.

[0015] Furthermore, a plurality of solar panels are installed on a side wall of the auxiliary cabin close to the buoy shell, and a charger and a battery are installed inside the buoy shell. The output end of the solar panel is connected to the battery through the charger. When charging is required, the auxiliary cabin is unfolded under the action of the telescopic connector, and the solar panel is exposed, which facilitates solar charging. At the same time, when charging is not required, the solar panel is protected between the auxiliary cabin and the buoy shell, reducing the probability of damage to the solar panel.

[0016] It is worth noting that an air pump is installed inside the buoy shell, and the air outlet of the air pump is connected to an inflatable air bag through an air guide tube.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention proposes a removable buoy for ocean observation. By setting a buoyancy lifting mechanism, when the buoy needs to be relocated, the inflatable airbag can be moved into the water body, and then the gravity block can be driven to float after inflation, which facilitates the relocation of the buoy. In addition, when not in use, the inflatable airbag of this device is not immersed in the water body, but is protected in a protective shell on the water surface, which greatly extends the service life of the device and has a good use effect.

[0019] Furthermore, by providing a rope-loosening prevention mechanism, the annular connecting belt inside the buoyancy lifting mechanism can be prevented from being loosened or entangled from the active roller and the driven roller when the gravity block moves upward.

[0020] 2. This invention proposes a removable buoy for ocean observation. By providing an auxiliary cabin, the device can increase the contact area with the water when the sea surface is rough, providing better stability for the device and preventing the buoy from capsizing.

[0021] And through the hydrological detection component set inside it, the water quality can be tested when needed, and the hydrological detection component can be protected when not in use;

[0022] At the same time, the solar panels installed on the auxiliary cabin can provide power for the device. When charging is not needed, the solar panels are protected between the auxiliary cabin and the buoy shell, reducing the probability of damage to the solar panels. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Example 1, with reference to Figure 1-8A portable buoy for ocean observation comprises a buoy shell 5 with a float at the bottom, a signal antenna 7 is installed on the top of the buoy shell 5, the bottom ends of the three side walls of the buoy shell 5 are hinged with auxiliary cabins 6, and a telescopic connection is installed between the auxiliary cabin 6 and the buoy shell 5, and a buoyancy lifting mechanism 4 is movably installed on the other three side walls of the buoy shell 5. The buoyancy lifting mechanism 4 is spaced apart from the auxiliary cabin 6, and the bottom end of the buoyancy lifting mechanism 4 is connected to a connecting frame 3 located below the buoy shell 5, and the buoyancy lifting mechanism 4 is provided with an inflatable airbag 406 which is movably connected to the connecting frame 3 after inflation, and the bottom end of the connecting frame 3 is fixed with a gravity block 1 through an anchor chain 2.

[0034] The buoyancy lifting mechanism 4 includes a protective shell 401 movably mounted on the outer side wall of the buoy shell 5, the bottom end of the protective shell 401 is open, a motor 403 is mounted on the outer side of the protective shell 401, the output shaft of the motor 403 is connected to a driving roller 404 rotatably connected to the inside of the buoy shell 5, and driven rollers 303 are mounted at the three corners of the connecting frame 3, an annular connecting belt 402 is connected between the driving roller 404 and the driven roller 303, an inflatable airbag 406 is mounted on the annular connecting belt 402 through a connecting block 405, and the inflatable airbag 406 is protected inside the protective shell 401 when not in use, an air pump is mounted inside the buoy shell 5, and the air outlet end of the air pump is connected to the inflatable airbag 406 through an air guide tube;

[0035] The cross-section of the connecting frame 3 is triangular, and the bottom end of the corner of the connecting frame 3 is rotatably connected to the driven roller 303 through the extended mounting bracket 302, and three corresponding through-limiting holes 301 are opened on the connecting frame 3. One side of the annular connecting belt 402 is located outside the connecting frame 3, and the other side of the annular connecting belt 402 and the connecting block 405 and the inflatable airbag 406 thereon slide through the through-limiting holes 301. The connecting block 405 and the inflatable airbag 406 are initially located inside the protective shell 401. When the device needs to move, the connecting block 405 and the inflatable airbag 406 pass through the through-limiting holes 301 and move to the bottom of the connecting frame 3. Then, the inflatable airbag 406 is inflated and limited to the bottom of the connecting frame 3 to generate buoyancy. The above-mentioned active roller 404, driven roller 303 and annular connecting belt 402 can also be replaced by existing sprockets, chain structures and other specific transmission structures with similar functions.

[0036] At the same time, a liquid pump 605 and a detection chamber 602 are installed inside the auxiliary chamber 6. The two ends of the detection chamber 602 are respectively connected to the water inlet pipe 604 and the drain pipe 601. The liquid pump 605 is installed on the water inlet pipe 604, and a detection probe is installed on the side wall of the detection chamber 602. The hydrological detection sensor group 603 is located inside the detection chamber 602. The hydrological detection sensor group 603 can be composed of a variety of existing sensors for detecting water quality. One end of the water inlet pipe 604 and the drain pipe 601 both extend to the outside of the auxiliary chamber 6, and the drain pipe 601 is located below the detection chamber 602 when the auxiliary chamber 6 is in a vertical state. When the auxiliary chamber 6 is in a vertical state and the detection is completed, the water inside the detection chamber 602 automatically flows out through the drain pipe 601 at the bottom under the action of gravity.

[0037] The above-mentioned telescopic connection includes an electric motor 2 8. Three slide grooves 501 corresponding to the auxiliary compartments 6 are opened on the outer wall of the buoy shell 5. The output shaft of the electric motor 2 8 is connected to a threaded rod 9 rotating inside the slide groove 501. The threaded rod 9 is threadedly connected to a slider 10 slidingly connected in the slide groove 501. A transmission rod 11 is hinged between the slider 10 and the corresponding auxiliary compartment 6. When encountering strong winds and waves on the sea, the telescopic connection drives the three auxiliary compartments 6 to expand, increasing the contact area between the device and the water body, providing better stability for the device, and preventing the device from tipping over.

[0038] When the device needs to be moved, the motor 403 on the buoyancy lifting mechanism 4 drives the active roller 404 to rotate, and the annular connecting belt 402 between the active roller 404 and the driven roller 303 drives the connecting block 405 and the inflatable airbag 406 thereon to pass through the limiting hole 301 and move to the bottom of the connecting frame 3. Then the air pump drives the inflatable airbag 406 to inflate and engage the limiting position below the connecting frame 3. The buoyancy generated by the inflatable airbag 406 drives the gravity block 1 to float up through the anchor chain 2, which drives the connecting frame 3 and the components connected thereto to move upward, making it convenient to drag the device through the hull to achieve the movement of the buoy.

[0039] In case of strong winds and waves, in order to make the device more stable, the telescopic connection is activated, and the output shaft of the second motor 8 drives the threaded rod 9 to rotate. The threaded rod 9 is threadedly connected to the slider 10, driving the slider 10 to move downward in the slide groove 501. The slider 10 drives the three auxiliary compartments 6 to rotate and expand around the buoy shell 5 through the transmission rod 11, thereby increasing the contact area between the device and the water body, providing better stability for the device and preventing the device from tipping over.

[0040] At the same time, when water body testing is required, after the three auxiliary cabins 6 are unfolded as mentioned above, the liquid pump 605 is started, and the liquid is pumped into the testing cabin 602 through the water inlet pipe 604, and the water quality of the liquid in the testing cabin 602 is tested through the hydrological detection sensor group 603. After the test is completed, when the auxiliary cabin 6 is in a vertical state and the test is completed, the water inside the testing cabin 602 automatically flows out through the drain pipe 601 at the bottom under the action of gravity, which is convenient for the next test.

[0041] Example 2, as Figure 7 As shown, different from embodiment 1, a rope loosening prevention mechanism is also installed between the buoyancy lifting mechanism 4 and the buoy shell 5, and the rope loosening prevention mechanism includes a connecting rope 16, a pulley 14 and a counterweight block 13 located inside the buoy shell 5. A plurality of mounting holes are opened at the top of the side wall of the buoy shell 5, and a pulley 14 is rotatably connected in the mounting hole. A connecting rope 16 is slidably connected to the pulley 14, and one end of the connecting rope 16 is fixedly connected to the counterweight block 13, and the other end of the connecting rope 16 is fixedly connected to the buoyancy lifting mechanism 4.

[0042] At the same time, corresponding tracks 15 are installed on the inner and outer walls of the buoy shell 5. The counterweight block 13 and the buoyancy lifting mechanism 4 are slidably connected to the track 15 through the sliding block. When the inflatable airbag 406 on the buoyancy lifting mechanism 4 moves to the bottom of the connecting frame 3 and is inflated to generate buoyancy, thereby driving the connecting frame 3 and the gravity block 1 at its bottom to move upward, when the pulling force of the gravity block 1 on the buoyancy lifting mechanism 4 is reduced, the counterweight block 13 drives the buoyancy lifting mechanism 4 to move upward through its own gravity and the action of the connecting rope 16, and slides on the track 15, preventing the annular connecting belt 402 on the buoyancy lifting mechanism 4 from being entangled or loosened due to the smaller spacing, ensuring that the annular connecting belt 402 is always in a straight state.

[0043] Example 3, as Figure 2 、 3 As shown in , 4, different from Example 2, a plurality of solar panels 12 are installed on a side wall of the auxiliary cabin 6 close to the buoy shell 5, a charger and a battery are installed inside the buoy shell 5, and the output end of the solar panel 12 is connected to the battery through the charger. When charging is required, the auxiliary cabin 6 is unfolded under the action of the telescopic connector, and the solar panel 12 is exposed, which facilitates solar charging. At the same time, when charging is not required, the solar panel 12 is protected between the auxiliary cabin 6 and the buoy shell 5, reducing the probability of damage to the solar panel 12.

[0044] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
