Description

Technical Field

[0001] The present invention relates to the technical field of marine environment observation equipment, and in particular to a waterproof seabed-based observation system for marine environment parameter observation, which can be used repeatedly for a long time and can obtain observation data in a timely manner. Background Art

[0002] As a commonly used marine environmental parameter observation platform, the seabed base is equipped with sensors, detection instruments and equipment, usually deployed on the offshore seabed, to collect long-term and synchronous data on seawater flow velocity, direction, temperature, salinity, pH, dissolved oxygen, turbidity, chlorophyll, waves and other parameters. It is of great significance for the construction of marine engineering, dredging of waterways, improvement of port environment, safe operations at sea, as well as research on marine dynamic sedimentology and marine environment.

[0003] Existing traditional seabed-based observations are mainly self-contained fixed-point observations. The seabed-based platform needs to be recovered regularly to complete data upload and battery replacement. Due to its long-term deployment on the seabed, mud and sand in the seawater will be deposited on the surface of the seabed, resulting in the monitoring equipment being unable to collect data normally and accurately. It is also easy to cause the seabed to be unable to be recovered or even lost, causing huge losses.

[0004] The Chinese invention patent with authorization announcement number CN 109866895 B discloses a seabed base, which uses an air tank to blow air into an air pipe. The gas in the air pipe blows away the silt, thereby achieving dredging. The airbag is inflated by an airbag inflation tank, and the airbag pops out of the airbag tank. The seawater provides buoyancy to the airbag and drives the seabed base to float to the water surface. First, although the seabed base has achieved the functions of dredging and self-floating, it will still be covered with mud and sand. The mud is only blown away by setting up compressed air tanks and air pipes, and it needs to be blown periodically. Otherwise, if it is not blown for a long time, it may lead to a large amount of silt deposition and cannot be blown away. High-frequency blowing consumes a lot of power and cannot achieve long-term effective anti-siltation and data collection. In addition, the seabed base is set up with an air pipe on the base. After blowing, the mud and sand are only stirred and turned. After stopping the blowing, the mud and sand will still fall on the surface of the seabed base. The dredging is not thorough. There is still a risk of being buried in silt after a long time, and the silt on the surface of the shell cannot be completely blown away by the air pipe. Secondly, although the seabed base has achieved buoyancy under the action of the buoyancy of the air bag, the air tank needs to be inflated every time it is put into use, which makes offshore construction complicated and costly.

[0005] In summary, although there are some seabed bases with dredging or self-floating functions in the prior art, there is still the problem of being covered by mud and sand and needing to be dredged, and there is also the situation of incomplete dredging. At the same time, the existing seabed base uses hydroacoustic communication to recover the seabed base and transmit data to the surface anchor buoy, which has high construction costs, and deep-water communication has high requirements on water depth and water environment. There are problems such as data loss, high power consumption, and inability to connect, resulting in the inability to recover the seabed base. At the same time, after the battery reaches its service life, the seabed base system still needs to be recovered as a whole; some near-shore seabed base observations use underwater cables to transmit data online, and the construction is complex and costly, and the laying of cables cannot be achieved in waters far from the shore.

DETAILED DESCRIPTION

[0030] To facilitate understanding of the present invention, the present invention is further explained below with reference to specific embodiments in conjunction with the accompanying drawings, and the specific embodiments do not constitute a limitation on the embodiments of the present invention.

[0031] Those skilled in the art should understand that the drawings are merely schematic diagrams of embodiments, and the components in the drawings are not necessarily necessary for implementing the present invention.

[0032] like Figures 1 to 9As shown, in a specific embodiment, a seabed-based observation system is provided, including a base 1, the base 1 is used to install a control cabin 4, various monitoring equipment such as a temperature sensor, a salinity sensor, a dissolved oxygen sensor, etc., a shell 2 is provided on the base 1, and the shell 2 can play a protective role. There is a housing cavity between the shell 2 and the base 1, and the control cabin 4, a power supply, and various monitoring equipment are in the housing cavity. The control cabin 4 is provided with a controller connected to the monitoring equipment, and a power module connected to the controller and the monitoring equipment. The power module supplies power to the controller and various monitoring equipment, and the monitoring equipment collects marine environmental parameters. The monitoring equipment is also connected to a communication antenna, which is connected to the controller. The communication antenna is used to upload the marine environmental parameters collected by the monitoring equipment. In the specific working process, the necessary power is provided to each component through the battery module, and the monitoring equipment is connected to the communication antenna for communication. When the seabed base floats up, the communication antenna sends out the monitored data. When external staff issues control instructions, such as the need to float or dive the seabed base, the corresponding control instructions are received by the communication antenna, and then the controller implements the air compressor 8 to inflate or exhaust the airbag 6 according to the specific control instructions, thereby further realizing the floating or diving of the seabed base.

[0033] In specific applications, the type and model of the monitoring equipment can be selected by those skilled in the art according to actual conditions. How to install the monitoring equipment is also common knowledge known to those skilled in the art and will not be elaborated here.

[0034] The base 1, as the matrix of the entire seabed base, can be made of materials with high density, can be immersed in seawater for a long time without destroying its own structural stability, and will not corrode, so that its own weight is relatively high, and it plays a role in supporting, increasing weight and lowering the center of gravity, so that the entire seabed base can be stably laid on the seabed. The outer shell 2 can set the surface to be an inclined plane, so that the mud and sand can easily slide down after falling on the surface and are not easy to deposit. In the seabed-based observation system provided in this embodiment, the shape of the base 1 is square, and the shape of the outer shell is set to be a quadrangular pyramid. At the same time, a plurality of diversion holes 3 are arranged on the four faces of the base 1 and the outer shell 2, and the diversion holes 3 can guide the flow of seawater to prevent the mud and sand from being blocked and deposited.

[0035] In order to achieve the buoyancy or diving of the seabed base, a ballast water tank 5 is provided on the base 1, and an air bag 6 is provided in the ballast water tank 5; the air bag 6 is inflated to squeeze out the water in the ballast water tank 5, and the ballast water tank 5 provides buoyancy for the seabed base as a whole. Furthermore, the buoyancy can be controlled by controlling the amount of air in the air bag 6, thereby controlling the depth of the seabed base as a whole to float or dive. For the setting of the ballast water tank 5, a square or circular space can be set at the bottom of the base 1 as a ballast water tank, and the central axis of the space coincides with the central axis of the base 1 to ensure the balance of buoyancy and the stability of the seabed base as a whole during the floating or diving process. After the air bag is filled with air, it can fill the entire ballast water tank to ensure that all the water in the ballast water tank is squeezed out. An air tank 7 is provided on the base 1 as an air source, and an air pump 8 is provided to connect the air tank 7 and the air bag through a connecting pipe 22. The air pump 8 inflates the air bag from the air tank 7 or extracts air from the air bag and returns it to the air tank 7, thereby expanding or shrinking the air bag.

[0036] Specifically, in this embodiment, the number of the ballast water tanks 5 is 4, and the 4 ballast water tanks 5 are symmetrically arranged at the four corners of the base 1 around the central axis of the base 1; the ballast water tanks 5 are cylindrical, the bottom of the ballast water tanks 5 are arranged on the base 1, and the top extends out of the shell 2. The 4 ballast water tanks 5 are symmetrically arranged and evenly distributed on the four corners of the base to ensure the balance of buoyancy, ensure the balance of the seabed base during floating or diving, and prevent it from tilting. The air storage tank 7 provided on the base 1 is connected to one end of the air compressor 8 through the connecting pipe 22, and the other end of the air compressor 8 is connected to the air bag 6 in each ballast water tank 5 through the connecting pipe 22. The controller is connected to the air compressor 8, and the power module is electrically connected to the air compressor 8 to provide power for it. When the controller receives the control command, it controls the air compressor 8 to inflate the air bag or extract air from the air bag.

[0037] Among them, under the action of the air compressor 8, when the air compressor 8 is running, the gas in the air tank 7 is filled into the air bag 6, the air bag 6 expands, presses out the water in the ballast tank 5, and the seabed base floats up; when the air compressor 8 is running in reverse, the gas in the air bag 6 is sucked into the air tank 7 by the air compressor 8, the air bag 6 shrinks, water enters the ballast tank 5, and the seabed base sinks. An air flow meter is set on the connecting pipe 22 to detect the amount of air entering each air bag in real time, and the air flow data is uploaded to the controller. The controller is used to control the start and stop of the air compressor 8, and then adjust the amount of air entering the air bag 6 to achieve the adjustment of the floating or diving depth of the seabed base. A solenoid valve 21 is also provided on the connecting pipe 22. When the air bag 6 is inflated, the controller controls the solenoid valve 21 to be in an open state. When the inflation is completed, the controller controls the solenoid valve 21 to be closed to prevent the air in the air bag 6 from flowing out. If the airbag 6 is fully inflated, it can fill the entire ballast tank 5, and the seabed base as a whole floats to the water surface. If there is no air in the airbag 6, the seawater fills the ballast tank 5, and the seabed base as a whole sinks to the seabed. By controlling the air content in the airbag 6, the seabed base can be suspended on the seabed surface and keep a certain distance from the seabed surface. By controlling the air content in the airbag 6 to continue to increase, the seabed base as a whole can be completely suspended in the seawater, so that the seabed base can be prevented from being submerged by mud, sand and rocks.

[0038] In specific practical applications, the shape of the ballast water tank 5 is not limited to a cylindrical shape, and those skilled in the art can set the shape of the ballast water tank 5 according to specific circumstances, such as setting it to a rectangular parallelepiped shape.

[0039] In order to realize reliable inflation of the airbag 6 by the air storage tank 7, a vent pipe 9 is provided on the bulkhead of the ballast water tank 5, one end of which is connected to the airbag 6 inside the ballast water tank 5. At the same time, a water hole 10 is provided at the bottom of the ballast water tank 5. When the airbag 6 expands, the water in the ballast water tank 5 flows out through the water hole 10. When the airbag 6 shrinks, seawater flows into the ballast water tank 5 through the water hole 10. Figure 3As shown, in this embodiment, two vent pipes 9 are provided on each ballast water tank 5, and the other end of the vent pipe 9 is connected to the vent pipe 9 of another ballast water tank 5 through a connecting pipe 22, and the air compressor 8 is connected to a connecting pipe 22 on the right side, and the two ends of the connecting pipe 22 are connected to the vent pipes 9 of the two ballast water tanks 5, and the other vent pipe 9 of the two ballast water tanks 5 is respectively connected to the vent pipes 9 of the two ballast water tanks 5 on the left side through another two sections of connecting pipes 22, and the other vent pipes 9 of the two ballast water tanks 5 on the left side are connected through another section of connecting pipe 22, so that the air pump 8 is first used to inflate the air bags 6 in the two ballast water tanks 5 on the right side, and then the air in the air bags 6 in the two ballast water tanks 5 on the right side is filled into the air bags 6 in the two ballast water tanks 5 on the left side through the connecting pipe 22, so as to realize the inflation of all the air bags 6. In specific applications, the air compressor 8 can also be synchronously connected to the four air bags 6 through the connecting pipe 22, and the four air bags 6 are inflated or deflated synchronously.

[0040] In a specific embodiment, the power module can be a battery. When the power module needs to be charged, the seabed base floats on the water surface as a whole, and uses solar energy to charge the battery. Specifically, in order to realize the charging of the power module, a solar panel assembly 12 can be set on the top of the shell 2, and the solar panel assembly 12 is connected to the power module. Among them, the solar panel assembly 12 may include a solar panel seat 13 connected to the top of the shell 2, and a plurality of solar panels 14 arranged around the solar panel seat 13. In this embodiment, since the shape of the shell 2 is a quadrangular pyramid, the overall shape of the solar panel assembly 12 is also set to a quadrangular pyramid. Each side of the shell 2 corresponds to a solar panel 14. Therefore, the number of solar panels 14 is four, and the four solar panels 14 are connected to each other around the solar panel seat 13 to form a quadrangular pyramid. When the seabed base floats on the water surface as a whole, the solar panel 14 receives solar energy and converts it into electrical energy, which is stored in the battery. When charging is not needed, the seabed is submerged in the seawater. In order to protect the solar panels from being affected or damaged by the complex environment in the seawater, a solar panel cover 16 may be provided to cover the solar panels 14 .

[0041] In a specific embodiment, in order to cover the solar panel 14 with a solar panel cover 16, a lifting mechanism 11 is provided on the base 1, the bottom end of the lifting mechanism 11 is connected to the upper surface of the base 1, and the top end of the lifting mechanism 11 extends out of the top of the shell 2 to connect the solar panel seat 13 of the solar panel assembly 12; the top of the shell 2 is provided with an opening 15, and the top of the shell 2 is rotatably connected with a plurality of solar panel covers 16, the solar panel covers 16 are located outside the top edge of the opening 15, and each solar cover 16 corresponds to a solar panel 14. In this embodiment, corresponding to the number of solar panels 14, the number of solar panel covers 16 is also four, the opening 15 is square, and each solar panel cover 16 corresponds to a side of the shell 2. The top edge of the opening 15 can be provided with a pivot to connect the solar panel cover 16, so that the solar panel cover 16 can be rotated. When the lifting mechanism 11 drives the solar panel assembly to rise, the solar panel cover 16 is opened, and when the lifting mechanism 11 drives the solar panel assembly to descend, the solar panel cover 16 is closed.

[0042] In order to realize the opening and closing of the solar panel cover 16, a plurality of push-pull components 17 are arranged in the accommodating cavity, and the number of the push-pull components 17 corresponds to the number of the solar panel covers 16. One end of each of the push-pull components 17 can be rotatably connected to one of the solar panel covers 16, and the other ends of all the push-pull components 17 are commonly connected to the lifting mechanism 11. When the lifting mechanism 11 rises, it drives one end of the push-pull component 17 to rise, and the other end of the push-pull component 17 pushes the solar panel cover 16 to flip outward, so that the solar panel cover 16 is in the open state. When the lifting mechanism 11 descends, it drives one end of the push-pull component 17 to descend, and the other end of the push-pull component 17 drives the solar panel cover 16 to flip inward, and the solar panel cover 16 covers the solar panel 14, so that the solar panel cover 16 is in the closed state.

[0043] like Figure 7As shown, the solar panel seat 13 and each solar panel 14 have a slot 25 for the push-pull assembly 17 to extend out, so that the push-pull assembly 17 can be movably connected to the solar panel cover 16. Specifically, the structure of the push-pull assembly 17 is composed of a plurality of rod assemblies that can be rotatably connected. For example, the push-pull assembly 17 includes a support rod 18 connected to the lifting mechanism 11. The connection between the support rod 18 and the lifting mechanism is a fixed connection. The support rod 18 is L-shaped. One end of the support rod 18 can be vertically connected to the lifting mechanism. The support rod 18 is connected to the side of the lifting mechanism 11. The other end of the support rod 18 can be rotatably connected to a transfer rod 19. The transfer rod 19 can be rotatably connected to the push-pull rod 20. The other end of the push-pull rod 20 can be movably connected to one side of the solar panel cover 16. The connection between the support rod 18 and the transfer rod 19 can be connected by a pivot, such as a notch at one end of the support rod 18, radial through holes at both sides of the notch, and a corresponding radial through hole at one end of the transfer rod 19. The rotation shaft passes through the notch and the radial through hole of the transfer rod 19 to realize the rotatable pivot connection between the support rod 18 and the transfer rod 19. Similarly, the transfer rod 19 and the push-pull rod 20 can also be connected by a pivot, such as a notch at the other end of the transfer rod 19, a radial through hole at one end of the push-pull rod 20, radial through holes at both sides of the notch, and a rotation shaft passes through to realize the rotatable pivot connection between the two. The other end of the push-pull rod 20 is also provided with a radial through hole, and the solar panel cover 16 is provided with two opposite ear plates on the side facing the solar panel 14, and through holes corresponding to the radial through holes are provided on the two ear plates, and the rotation shaft passes through to realize the rotatable connection between the push-pull rod 20 and the solar panel cover 16. In a specific application, the lifting mechanism 11 can be an electric telescopic rod, and the extension and retraction of the electric telescopic rod is controlled by a controller. The support rod 18 is connected to the telescopic end of the electric telescopic rod. When the electric telescopic rod is extended, the support rod 18 is driven to rise, and the rise of the support rod 18 drives the transfer rod 19 to rise, and the rise of the transfer rod 19 drives the push-pull rod 20 to rise. Since one end of the push-pull rod 20 is connected to the solar panel cover 16, when the push-pull rod 20 rises, it provides an outward thrust to the solar panel cover 16, and opens the solar panel cover 16. On the contrary, when the electric telescopic rod is retracted, it drives the support rod 18 to drop, and the drop of the support rod 18 drives the transfer rod 19 to drop, and the drop of the transfer rod 19 drives the push-pull rod 20 to drop, and provides an inward pulling force to the solar panel cover 16, so that the solar panel cover 16 is pulled back to cover the solar panel 14.

[0044] When the seabed base observation system described in the embodiment of the present invention is used, the controller receives a control command from an external staff member such as a wireless remote controller to control the air compressor 8 to fill the air in the air tank 7 into the airbag 6. The airbag 6 provides buoyancy for the seabed base, so that the seabed base floats up, suspends above the seabed without touching the seabed, or completely suspends in the seawater, thereby avoiding the accumulation of mud and sand and rocks to submerge the seabed base. When the airbag 6 is fully expanded, all the water in the ballast tank 5 is squeezed out, and the seabed base floats on the surface of the water as a whole. At this time, data can be sent through the communication antenna, such as the communication antenna can be installed on the top of the solar panel assembly 12. If the battery needs to be charged, the air compressor 8 is controlled to inflate the airbag 6 completely, and the seabed base completely floats on the water surface. The controller controls the lifting mechanism 11 to lift the solar module 12 according to the control command. At the same time, under the action of the push-pull assembly 17, the solar panel cover 16 is opened, and the solar panel 14 receives sunlight and converts solar energy into electrical energy and stores it in the battery. When charging is completed, the controller controls the lifting mechanism 11 to retract, and under the action of the push-pull assembly 17, the solar panel cover 16 is closed. The controller controls the air compressor to pump the air in the air bag 6 back into the air storage tank 7. As the air bag 6 shrinks, seawater enters the ballast water tank 5, and the seabed base begins to dive.

[0045] In summary, the seabed base observation system described in the embodiment of the present invention, by setting a ballast tank 5, cooperating with the internal airbag 6, by inflating or exhausting air into the airbag 6, adjusting the size of the buoyancy, the seabed base as a whole can float, hover or dive in the water, there is no need to directly lay the seabed base on the seabed surface, avoiding the accumulation of mud and sediment, and there is no siltation problem caused by the long-term accumulation of mud and sediment on the surface of the seabed base; by inflating or exhausting air into the airbag 6 by the air compressor 8, the seabed base can float and dive by itself, and data transmission and battery charging can be performed after floating, without the need to replace the battery, and data transmission can be performed after the seabed base floats by setting a communication antenna, and no underwater acoustic communication is required for seabed base recovery and data transmission, which greatly reduces the cost and realizes long-term fixed-point continuous observation. At the same time, a gripping anchor 23 and an anchor rope 24 can also be set, the gripping anchor 23 sinks to the seabed, one end of the anchor rope 24 is connected to the gripping anchor 23, and the other end is connected to the bottom of the base 1, to ensure that the fixed-point observation of the seabed base will not drift away and be lost with the water flow.

[0046] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative work on the basis of the technical solution disclosed in the present invention should be included in the scope of protection of the present invention.
