Description

Technical Field

[0001] This invention belongs to the field of environmental monitoring equipment technology, specifically a marine environmental monitoring device. Background Art

[0002] Ocean buoys are a common type of marine environmental monitoring equipment. They are mainly observation buoys anchored at sea and can automatically observe marine hydrology, water quality, and meteorology. They can collect marine hydrology, water quality, and meteorological data required for marine scientific research, offshore oil development, and national defense construction on a long-term and continuous basis according to fixed requirements.

[0003] When ocean buoys are in operation, their internal sensors typically monitor ocean hydrology and water quality in real time to achieve long-term monitoring. Because ocean buoys move slowly with the waves and have smooth bottoms, they easily become attachment sites for organisms such as barnacles and oysters. The attachment of a large number of barnacles and oysters not only causes the ocean buoy to be corroded, resulting in a loss of luster and affecting its visibility range, but also affects the detection function of the sensors when barnacles and oysters attach to them. In severe cases, it can even cause the sensors to become completely inoperable. Therefore, how to effectively prevent biological attachment has become one of the directions for the optimization of ocean buoys.

[0004] For example, a Chinese patent discloses a marine environmental monitoring buoy platform, publication number CN119284046B. This patent can achieve a full-coverage scouring effect on the outer wall of the ecological monitor, thereby effectively preventing marine organisms such as barnacles and oysters from parasitizing the ecological monitor. However, in actual application, it was found that simple seawater scouring can only remove algae and other plants with low attachment strength. For organisms with high attachment strength such as barnacles and oysters, the effect of low-intensity seawater scouring is poor.

[0005] In view of this, the present invention proposes a marine environmental monitoring device to solve the above-mentioned technical problems. Summary of the Invention

The detection component consists of two sets of sensors with the same configuration, and the two sets of sensors are respectively installed at both ends of the rotating wheel. The drive unit is mounted on the buoy, and its output end is connected to the rotating wheel. The drive unit is used to drive the rotating wheel to rotate periodically in the rotating chamber. The drive unit is electrically connected to the photovoltaic power generation system. A focusing cover is fixedly installed on the top of the buoy, which is used to concentrate sunlight to illuminate the detection component.

[0008] Preferably, a heating tank is fixedly installed inside the rotating cavity. The heating tank is a container with an open top. A photothermal conversion element is installed inside the heating tank. The heating tank is made of heat-insulating material. A water replenishment box is fixedly installed on the rotating wheel. The water replenishment box is set with an opening facing the heating tank. The water replenishment box is used to replenish seawater into the heating tank.

[0009] Preferably, an elastic connecting rod is rotatably mounted on the rotating wheel, and the detection component is connected to the rotating wheel through the elastic connecting rod. In the initial state, the detection component located at the top extends into the heating groove.

[0010] Preferably, the top opening of the heating groove is higher than the sea level, a spring telescopic rod is fixedly installed inside the heating groove, a fine filter belt is fixedly installed at the top opening of the heating groove, the photothermal conversion element is embedded in the middle of the fine filter belt, the spring telescopic rod is located below the photothermal conversion element, and the spring telescopic rod is made of a heat-conducting material.

[0011] Preferably, after the detection component is detached from the heating tank, the fine filter belt, supported by the spring telescopic rod, takes the form of a cone-shaped structure with the opening facing downwards; When the detection component is located inside the heating tank, the fine filter belt forms an upward-opening conical structure under the pressure of the detection component.

[0012] Preferably, a driven wheel is rotatably mounted on the rotating wheel. The rotating wheel is a hollow annular frame structure. The driven wheel extends into the inner cavity of the rotating wheel, and an eccentric wheel is fixedly mounted on the driven wheel within the inner cavity of the rotating wheel. A movable frame is slidably mounted within the inner cavity of the rotating wheel. The movable frame is sleeved outside the eccentric wheel. A steel wire rope is installed in the inner cavity of the rotating wheel. The elastic connecting rod is a hollow corrugated rod. The steel wire rope connects the movable frame and the detection component in series.

[0013] Preferably, the focusing cover consists of a focusing mirror and a glass cover. The focusing mirror is a conical structure, and the glass cover is installed inside the focusing mirror. The buoy has a drainage hole for draining seawater between the focusing mirror and the glass cover. The glass cover is an arc-shaped structure.

[0014] Preferably, a collection ring is fixedly installed at the bottom of the inner wall of the glass cover. The collection ring is used to collect the distilled water condensed on the glass cover.

Therefore, under the periodic switching action, the flow of high-temperature seawater can enhance the inactivation effect on attached organisms. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 10 As shown, the marine environmental monitoring device of the present invention includes a buoy 1 and a photovoltaic power generation system 11 and a detection component 12 installed on the buoy 1. In the present invention, the photovoltaic power generation system 11 is a collection of photovoltaic panels, batteries and supporting facilities such as transmission lines and control circuits. The photovoltaic power generation system 11 is used for photovoltaic power generation and provides power to the marine environmental monitoring device. The detection component 12 is a collection of sensors for detecting marine hydrology and water quality, including but not limited to water quality sensors, water temperature sensors and other sensors that extend underwater for detection. In addition, in the present invention, meteorological monitoring equipment such as wind cups are also installed above the buoy 1. It also includes a rotating cleaning mechanism, which is installed on the buoy 1 and is used to clean marine organisms on the detection component 12; The rotary cleaning mechanism includes a rotary wheel 21, a drive component 22, and a focusing cover; The buoy 1 has a rotating cavity 2 that runs vertically through the middle. The rotating wheel 21 is rotatably installed in the rotating cavity 2. The detection component 12 consists of two sets of sensors with the same configuration, and the two sets of detection components 12 are respectively installed at both ends of the rotating wheel 21. The driving component 22 is mounted on the buoy 1. The output end of the driving component 22 is connected to the rotating wheel 21 for transmission. The driving component 22 is used to drive the rotating wheel 21 to rotate periodically in the wheel rotation cavity 2. The driving component 22 is electrically connected to the photovoltaic power generation system 11. The driving component 22 is the active component and is used to drive the rotating wheel 21 to rotate. In this embodiment, the driving component 22 is a drive motor. The driving component 22 is connected to one end of the rotating wheel 21 through a gear set for transmission. When the drive motor is started under the control of a preset program, it can drive the rotating wheel 21 to rotate through the meshing transmission. It should also be noted that in this embodiment, the preset program for controlling the drive motor is pre-written and starts the drive motor periodically with time as a reference, and controls the rotating wheel 21 to rotate at a fixed angle through the drive motor. A concentrator is fixedly installed on the top of the buoy 1, which is used to concentrate sunlight to irradiate the detection component 12.

[0023] When the ocean buoy 1 is in operation, it uses the detection component 12 installed on it to detect marine environmental parameters in real time, thereby forming long-term monitoring. Since the ocean buoy 1 mostly drifts in the near-shore area and its position is in a state of flux, it is not convenient to perform too frequent manual maintenance on the ocean buoy 1. During long-term monitoring, larvae of organisms such as barnacles and oysters will adhere to the underwater part of the ocean buoy 1 through the gel secreted by themselves. In order to avoid the impact of attached organisms on the detection component 12, the present invention is equipped with a rotating wheel 21 cleaning mechanism. By periodically cleaning the detection component 12, the attached larvae are deactivated and removed, ultimately maintaining the long-term normal operation of the detection component 12.

[0024] Specifically, in this invention, at least two sets of detection components 12 are provided, with each set installed at one end of the rotating wheel 21. When the ocean float is operating normally in the ocean, the photovoltaic power generation system 11 converts light energy into electrical energy for storage and supplies power to the detection components 12. Simultaneously, under the control of a pre-set program, the drive component 22 is periodically activated. After activation, the drive component 22 drives the rotating wheel 21 to rotate via a transmission. In this embodiment, the rotating wheel 21 rotates 180 degrees at a time. When the drive component 22 drives the rotating wheel 21 to rotate, the positions of the upper and lower sets of detection components 12 are switched. The lower detection component 12 extends into the seawater to detect the marine environment, while the upper detection component 12 is close to the concentrator, which focuses the surrounding light and illuminates it. Inside the rotating chamber 2, when sunlight gathers, it generates heat, which in turn heats the detection component 12 located above. Under high temperature and strong light, the marine larvae adhering to the detection component 12 will die quickly. The high temperature will also weaken the adhesiveness of the gel secreted by barnacles. During the periodic rotation of the rotating wheel 21, the seawater washes away the dead marine organisms, accelerating their removal. It should be noted that in order to reduce the chance of attached marine organisms growing and to avoid excessive waste of electrical energy, the rotation cycle of the drive component 22 is preferably 24 hours in this invention. That is, the upper and lower monitoring devices are switched every day. It should also be noted that in order to avoid damage to the detection component 12 under sunlight, the detection component 12 should be made of a material that is resistant to light, aging, and high temperature.

[0025] This invention utilizes the principle of concentrating sunlight to generate heat. During the long-term use of the ocean buoy 1, the two sets of detection components 12 are periodically switched. Strong light and high temperature are used to inactivate, reduce adhesion, and clean marine organisms adhering to the detection components 12. Therefore, during long-term use, the impact of marine organisms on the detection components 12 can be effectively reduced, thereby ensuring that the ocean buoy 1 can monitor the marine environment for a long time.

[0026] In a preferred embodiment of the present invention, a heating groove 23 is fixedly installed inside the rotating cavity 2. The heating groove 23 is a container with an open top. A photothermal conversion element 24 is installed inside the heating groove 23. The heating groove 23 is made of heat-insulating material. A water replenishment box 25 is fixedly installed on the rotating wheel 21. The water replenishment box 25 is opened at one end facing the heating groove 23. The water replenishment box 25 is used to replenish seawater into the heating groove 23.

[0027] An elastic connecting rod 26 is rotatably mounted on the rotating wheel 21. The detection component 12 is connected to the rotating wheel 21 through the elastic connecting rod 26. In the initial state, the detection component 12 located at the top extends into the heating groove 23.

[0028] To further enhance the inactivation and cleaning effect on marine organisms on the detection component 12, in this invention, a heating groove 23 is fixedly installed inside the rotating cavity 2. The heating groove 23 is a container with an open top. Under the action of the light-concentrating hood, strong light shines into the rotating cavity 2, and part of the light shines onto the photothermal conversion element 24 inside the heating groove 23. Under the action of the photothermal conversion element 24, the efficiency of light energy conversion into heat energy is accelerated. The heat energy heats the seawater in the heating groove 23. At the same time, the detection component 12 is rotatably connected to the rotating wheel 21 through the elastic connecting rod 26. Therefore, after the rotating wheel 21 rotates in one cycle, the detection component 12 located above will be pulled by gravity to extend the elastic connecting rod 26 into the heating groove 23, thereby utilizing... The detection component 12 is immersed in heated seawater. The fluidity of the seawater accelerates the penetration of heat into the marine organisms. According to relevant research data, barnacles will be rapidly inactivated at a water temperature of 60 degrees Celsius, and their gelatinous viscosity will also decrease. Therefore, under the periodic switching action, the flow of high-temperature seawater can enhance the inactivation effect on the attached organisms. As the heating continues, the seawater in the heating tank 23 will gradually evaporate, causing the water level in the heating tank 23 to gradually decrease. In order to allow the detection component 12 to be immersed in hot water for a long time, a water replenishment box 25 is also provided on the rotating wheel 21 in this invention. As the water replenishment box 25 rotates with the rotating wheel 21, the seawater in the heating tank 23 will be replenished.

[0029] In a preferred embodiment of the present invention, the top opening of the heating groove 23 is higher than the sea level, a spring telescopic rod 3 is fixedly installed inside the heating groove 23, a fine filter belt 31 is fixedly installed at the top opening of the heating groove 23, the photothermal conversion element 24 is embedded in the middle of the fine filter belt 31, the spring telescopic rod 3 is located below the photothermal conversion element 24, the spring telescopic rod 3 is made of a heat-conducting material, and the surface of the fine filter belt 31 and the inner wall of the heating groove 23 are coated with a photothermal conversion coating to enhance the photothermal efficiency.

[0030] After the detection component 12 is detached from the heating tank 23, the fine filter belt 31, supported by the spring telescopic rod 3, forms a cone-shaped structure with the opening facing downwards. When the detection component 12 is located inside the heating tank 23, the fine filter belt 31 forms an upward-opening conical structure under the pressure of the detection component 12.

[0031] As the hot water heats the marine organisms, they gradually die, and their viscosity decreases accordingly. To prevent the marine organisms from accumulating in the heating tank 23, a spring-loaded telescopic rod 3 and a fine filter belt 31 are installed inside the heating tank 23. Initially, under the pressure of the detection component 12 above, the fine filter belt 31 compresses the spring-loaded telescopic rod 3 and extends into the heating tank 23, forming an upward-opening conical structure. When the marine organisms on the detection component 12 fall off, the fine filter belt 31 supports them. During the rotation of the rotating wheel 21, as the rotating wheel 21 and the detection component 12 detach... Under the elastic reset action of the spring telescopic rod 3, the fine filter belt 31 is gradually pushed upward in the heating tank 23, eventually forming a cone-shaped structure with the opening facing downward. During this process, marine organisms on the fine filter belt 31 fall into the ocean through the gap between the heating tank 23 and the wheel rotation chamber 2 under the action of gravity. After the wheel 21 completes its rotation, the fine filter belt 31 is compressed again. During the periodic operation, it can effectively prevent marine organisms from accumulating in the heating tank 23. It should be noted that the fine filter belt 31 is a filter material with a small pore size and is mainly used for solid-liquid separation.

[0032] In a preferred embodiment of the present invention, a driven wheel 4 is rotatably mounted on the rotating wheel 21. The rotating wheel 21 is a hollow annular frame structure. The driven wheel 4 extends into the inner cavity of the rotating wheel 21, and an eccentric wheel 41 is fixedly mounted on the driven wheel 4 within the inner cavity of the rotating wheel 21. A movable frame 42 is slidably mounted within the inner cavity of the rotating wheel 21. The movable frame 42 is sleeved outside the eccentric wheel 41. A steel wire rope 43 is installed in the inner cavity of the rotating wheel 21. The elastic connecting rod 26 is a hollow corrugated rod. The steel wire rope 43 connects the movable frame 42 and the detection component 12 in series.

[0033] The bottom end of the spring telescopic rod 3 is fixedly installed with a spray pipe 54, which extends above the fine filter belt 31. The bottom end of the spring telescopic rod 3 is provided with a suction hole 55, and a one-way valve is installed in both the spray pipe 54 and the suction hole 55.

[0034] Electromagnets 56 are fixedly installed at both ends of the spring telescopic rod 3. The electromagnets 56 are electrically connected to the photovoltaic power generation system 11. The electromagnets 56 are used to forcibly control the spring telescopic rod 3 to perform telescopic movement.

[0035] During long-term operation, the lower end of the rotor 21 extends into the seawater. Under the impact of the ocean current, the driven wheel 4 at the lower end of the rotor 21 will be driven to rotate by the current. When the driven wheel 4 rotates, it will cause the eccentric wheel 41 to rotate inside the rotor 21. Since a movable frame 42 is slidably installed inside the rotor 21 and is fitted onto the eccentric wheel 41, the rotation of the eccentric wheel 41 will drive the movable frame 42 to perform periodic reciprocating motion. Since the movable frame 42 and the detection component 12 are connected in a ring by a steel wire rope 43, during the periodic motion of the movable frame 42, in conjunction with the gravity of the two detection components 12, both detection components 12 will perform small-amplitude up-and-down reciprocating motions. The up-and-down reciprocating motion of the detection components 12 will improve the efficiency of the removal of marine organisms attached to the detection components 12. At the same time, the up-and-down motion of the detection component 12 located above will also improve the efficiency of the removal of marine organisms attached to the detection components 12. The movement also causes the spring telescopic rod 3 and the fine filter belt 31 to sway up and down, thereby using seawater to flush the mesh of the fine filter screen and reduce the probability of the fine filter belt 31 being completely blocked. The up and down movement of the spring telescopic rod 3, in conjunction with the one-way valve in the suction hole 55 and the jet pipe 54, forms a piston-type pumping structure, which draws and pumps the seawater from the bottom of the heating tank 23 to the top of the fine filter belt 31, thereby repeatedly filtering the seawater. Combined with the deformation of the fine filter belt 31, this further enhances the cleaning effect on the heating tank 23. The electromagnet 56 is used to periodically conduct when the seawater has poor flow under the control of a pre-set program. When it is conducting, the switching of the current direction causes one of the electromagnets 56 to change its magnetism, thereby forcibly driving the spring telescopic rod 3 to move up and down, thereby accelerating the cleaning effect on the residue and salt crystals below the fine filter belt 31.

[0036] The focusing cover consists of a focusing mirror 5 and a glass cover 51. The focusing mirror 5 is a conical structure, and the glass cover 51 is installed inside the focusing mirror 5. The buoy 1 has a drainage hole for draining seawater between the focusing mirror 5 and the glass cover 51. The glass cover 51 is an arc-shaped structure.

[0037] A collection ring 52 is fixedly installed on the bottom of the inner wall of the glass cover 51. The collection ring 52 is used to collect the distilled water condensed on the glass cover 51. An extension tube 53 is fixedly installed on the inner side of the collection ring 52. The extension tube 53 extends to the top of the heating tank 23. The extension tube 53 is made of steel wire reinforced hose.

[0038] The condenser lens 5 focuses sunlight, while the glass cover 51, together with the seawater at the bottom of the float, seals the rotating chamber 2. Therefore, under the action of sunlight, the steam formed by the evaporation of seawater is not easily discharged to the outside. As the steam flows, it will heat the inner cavity of the rotating chamber 2. When the steam condenses on the glass cover 51, it will flow along the glass cover 51. Finally, under the action of the collecting ring 52 and the extension tube 53, the distilled water is transported back to the heating tank 23 to replenish the water in the heating tank 23.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
