Description

Technical Field

[0001] This utility model relates to the technical field of marine engineering, and in particular to an auxiliary system for ocean upwelling. Background Technology

[0002] Phytoplankton are crucial for driving marine productivity, but the nutrients required by phytoplankton are often locked in deep, cold waters separated by thermoclines (barriers of temperature inversion between warm and cold water layers), resulting in extremely limited ocean surface productivity due to nutrient scarcity. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary ocean upwelling system that can bring nutrient-rich seabed water up to a target area, thereby improving marine productivity.

[0004] To achieve the above objectives, the solution of this utility model is: An auxiliary ocean upwelling system includes a float, tubing, and an underwater thruster; The float is set up on the sea surface; The fitting includes a horizontal output pipe and at least one vertical drain pipe; The horizontal output pipe is located at the bottom of the float and has an output port; the upper end of the vertical drain pipe is connected to the horizontal output pipe, the lower end of the vertical drain pipe extends downward to the seabed, and the lower part of the vertical drain pipe has an input port. The underwater thruster is installed at the upper end of the vertical diversion pipe and is used to draw seawater from the vertical diversion pipe into the horizontal output pipe. The vertical drainage tube includes a protective outer tube and several inner guide tubes; the upper end of the protective outer tube is connected to and communicates with the horizontal output tube, and the lower end of the protective outer tube is the input port; the upper and lower ends of each inner guide tube are open and tightly inserted into the interior of the protective outer tube; the gap between each inner guide tube and the protective outer tube is sealed by a filler; a filter end cap that covers the input port is installed at the lower end of the protective outer tube.

[0005] Furthermore, both the horizontal output pipe and the protective outer pipe are made of PVC pipe; the inner guide pipe is made of HDPE double-wall corrugated pipe.

[0006] Furthermore, the outer protective tube has a diameter of 12 inches; the inner guide tubes are three in number, each with a diameter of 6 inches.

[0007] Furthermore, the filler is a foam filler; the filter end cap is a conical filter end cap or a cylindrical filter end cap, and the filter end cap is densely covered with several input holes that connect to the input port.

[0008] Furthermore, the underwater thruster is a shaftless rim thruster.

[0009] Furthermore, the upper end of the vertical drainage pipe is connected to the horizontal output pipe through a downstream tee fitting; the two ends of the main pipe of the downstream tee fitting are connected to the horizontal output pipe, and the branch pipe of the downstream tee fitting is connected to the upper end of the vertical drainage pipe.

[0010] Furthermore, another underwater thruster is installed on the arc side of the horizontal output pipe near the downstream tee.

[0011] Furthermore, the fitting includes two or more vertical drain pipes; each vertical drain pipe is spaced apart along the length of the horizontal output pipe; at least one output port is provided on the horizontal output pipe between adjacent vertical drain pipes.

[0012] Furthermore, the floating body includes a platform deck and several longitudinal tube floats; each longitudinal tube float is distributed laterally at intervals below the platform deck, and the longitudinal tube floats and the platform deck are supported and connected by several longitudinally spaced support members; the tubes are multiple longitudinally spaced, and the horizontal output pipes of the tubes extend laterally and are respectively installed and connected below each longitudinal tube float, and the output port is located below the sea surface; the vertical drainage pipe is located between the laterally adjacent longitudinal tube floats and extends towards the seabed.

[0013] Furthermore, it also includes a power generation device; the power generation device is installed on the float and electrically connected to the underwater propulsion device; the power generation device is one or more combinations of a solar generator, a wind generator, a tidal generator, and a diesel generator.

[0014] By adopting the above technical solution, an underwater propulsion device can generate an upwelling current within the vertical diversion pipe. This allows a large amount of nutrient-rich water from the seabed to be diverted through the vertical diversion pipe and then output to the sea surface via a horizontal output pipe located below the float. This provides nutrients to phytoplankton, promoting their growth, which in turn provides food for fish and shrimp, thereby increasing marine productivity. Furthermore, the protective outer pipe protects the inner diversion pipe, preventing system failure due to damage. Simultaneously, multiple inner diversion pipes tightly fitted together within the protective outer pipe increase its structural strength. Filling the gaps with material and installing filter end caps at the lower ends not only filters the seawater at the inlet, preventing fish from being sucked in, but also provides limiting protection for each inner diversion pipe, ensuring a robust and reliable overall structure that is not easily detached, thus improving system reliability.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] like Figures 1 to 4 As shown, an auxiliary ocean upwelling system according to this embodiment includes a float 1, a pipe 2, and an underwater thruster 3.

[0019] See Figure 4 The float 1 is set floating on the sea surface; the float 1 can be a floating boat, a floating platform or other structure.

[0020] like Figure 1 The fitting 2 includes a horizontal output pipe 21 and at least one vertical drain pipe 22; the horizontal output pipe 21 is located at the bottom of the float 1 and has an output port 23; the upper end of the vertical drain pipe 22 is connected to the horizontal output pipe 21, the lower end of the vertical drain pipe 22 extends downward to the seabed, and the lower part of the vertical drain pipe 22 has an input port 24; the lower input port 24 of the fitting 2 is connected to the nutrient-rich waters of the seabed, while the upper output port 23 of the fitting 2 is connected to the nutrient-deficient sea surface.

[0021] The underwater thruster 3 is installed at the upper end of the vertical diversion pipe 22 and is used to draw seawater from the vertical diversion pipe 22 into the horizontal output pipe 21. That is, the underwater thruster 3 can generate an upwelling current in the vertical diversion pipe 22, which can draw a large amount of nutrient-rich water from the seabed into the horizontal output pipe 21 located below the float 1 and then output it to the sea surface, providing nutrients for phytoplankton and promoting their growth. The growth of phytoplankton can provide food for fish and shrimp, thereby improving marine productivity.

[0022] See Figure 2 and Figure 3 The vertical drainage pipe 22 includes a protective outer pipe 221 and several inner guide pipes 222; the upper end of the protective outer pipe 221 is connected to and communicates with the horizontal output pipe 21, and the lower end of the protective outer pipe 221 is the input port 24; the upper and lower ends of each inner guide pipe 222 are open and tightly inserted into the interior of the protective outer pipe 221; the gap between each inner guide pipe 222 and the protective outer pipe 221 is sealed by a filler 223; a filter end cap 224 covering the input port 24 is installed at the lower end of the protective outer pipe 221.

[0023] Therefore, by setting up a protective outer tube 221, the inner guide tube 222 can be protected, preventing damage to the inner guide tube 222 from causing system failure. At the same time, setting multiple inner guide tubes 222 tightly installed inside the protective outer tube 221 can also increase the structural strength of the protective outer tube 221. Moreover, by setting filler 223 in the gaps and installing filter end cap 224 at the lower end, not only can the seawater in the inlet 24 be filtered to prevent fish from being sucked into the inlet, but it can also limit and protect each inner guide tube 222. This makes the overall structure of the protective outer tube 221 and the inner guide tube 222 firm, reliable and not easy to fall off or separate.

[0024] The upper and lower ends of each inner guide tube 222 are open, and the underwater thruster 3 can be installed in the protective outer tube 221 above each inner guide tube 222 to facilitate the upward flow of seawater. The filter end cap 224 can be covered on the lower end of the protective outer tube 221, and the filter end cap 224 is densely covered with several input holes 225 that connect to the input port 24; the number of output ports 23 can be multiple.

[0025] In this embodiment, both the horizontal output pipe 21 and the protective outer pipe 221 can be made of 12-inch diameter PVC (Polyvinyl chloride) pipe; there can be three inner guide pipes 222, and each of them can be made of 6-inch diameter HDPE (High Density Polyethylene) double-wall corrugated pipe; using existing common PVC pipes and HDPE double-wall corrugated pipes can reduce production and development costs and facilitate the promotion and application of this system; in addition, the double-wall corrugated pipes used in the inner guide pipes 222 have the advantages of not being crushed, twisted or torsioned, and are convenient for transportation and transfer.

[0026] Meanwhile, because the double-wall corrugated pipe has a flexible and deformable function, three 6-inch HDPE double-wall corrugated pipes can be tightly fitted into a 12-inch PVC pipe. The slight deformation of the double-wall corrugated pipe during the assembly and extrusion process will not affect the drainage effect of its smooth inner wall and will not obstruct the flow of seawater.

[0027] In this embodiment, the dimensions of the outer protective tube 221 and the inner guide tube 222 are selected based on the dimensions of existing common pipe fittings, which can save production costs. Of course, this does not mean that it is a limitation. In practice, large-diameter pipes can also be custom-made according to size requirements.

[0028] like Figure 4 As shown, in this embodiment, the filter end cap 224 can be a conical filter end cap 224 or a cylindrical filter end cap 224. Both the conical filter end cap 224 and the cylindrical filter end cap 224 are densely covered with a number of input holes 225.

[0029] In this embodiment, the filler 223 can be a foam filler 223. It can fill the gaps and improve the structural strength of the vertical drainage tube 22.

[0030] In this embodiment, the underwater thruster 3 is a shaftless rim thruster.

[0031] like Figure 1 In this embodiment, the upper end of the vertical drainage pipe 22 can be connected to the horizontal output pipe 21 via a downstream tee fitting 25. The two ends of the main pipe 251 of the downstream tee fitting 25 are connected to the horizontal output pipe 21, and the branch pipe 252 of the downstream tee fitting 25 is connected to the upper end of the vertical drainage pipe 22. The downstream tee fitting 25 can also be made of PVC for easy integration with the horizontal output pipe 21. The branch pipe 252 of the downstream tee fitting 25 can be connected to the upper end of the protective outer pipe 221 of the vertical drainage pipe 22, allowing the ocean upwelling current within the vertical drainage pipe 22 to flow more smoothly into the horizontal output pipe 21.

[0032] Furthermore, another underwater thruster 3 may be installed on the arc side of the horizontal output pipe 21 near the downstream tee 25. This other underwater thruster 3 may have the same structure as the underwater thruster 3 in the vertical diversion pipe 22. This can enhance the efficiency of the horizontal flow output of seawater in the horizontal output pipe 21.

[0033] In this embodiment, the pipe fitting 2 may include two or more vertical drainage pipes 22; each vertical drainage pipe 22 may be spaced apart along the length direction of the horizontal output pipe 21; at least one output port 23 is provided on the horizontal output pipe 21 between adjacent vertical drainage pipes 22. In this way, the amount of ocean upwelling can be increased, and the system's transport efficiency can be improved.

[0034] like Figure 4 In this embodiment, the floating body 1 may include a platform deck 11 and several longitudinal tube floats 12. Each longitudinal tube float 12 may be made of hollow round tubes or other tubular components, which can float on the sea surface and provide buoyancy to the platform deck 11, on which people can walk and work or carry out other marine activities.

[0035] Each longitudinal tube float 12 is distributed laterally at intervals below the platform deck 11, and the longitudinal tube float 12 and the platform deck 11 are supported and connected by several longitudinally spaced support members 13.

[0036] The pipe fitting 2 can also be multiple longitudinally spaced (the figure shows a schematic drawing of several examples). Specifically, the horizontal output pipe 21 of the pipe fitting 2 extends laterally and is installed below each longitudinal pipe float 12, and the output port 23 is located below the sea surface; the vertical drainage pipe 22 is located between the laterally adjacent longitudinal pipe floats 12 and extends towards the seabed.

[0037] Each horizontal output pipe 21 can be installed and fixed below each vertical pipe float 12 to improve the stability of the horizontal output pipe 21 and the vertical drainage pipe 22 and prevent them from drifting with the current.

[0038] In this embodiment, the system may further include a power generation device 4, which may be installed on the platform deck 11 and is electrically connected to the underwater thruster 3 to provide power to the underwater thruster 3.

[0039] The power generation device 4 can be one or more combinations of a solar generator 41, a wind turbine generator 42, a tidal generator, and a diesel generator. For example, a diesel generator can be combined with the aforementioned generators, and the diesel generator can be used as a backup generator to ensure the system's all-weather operating efficiency even on cloudy days or when there is no wind.
