[0018] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0019] The technical solution adopted by this utility model to solve its technical problem is: like Figures 1 to 3 As shown, some embodiments of this utility model disclose a portable seabed air curtain device. In some embodiments, the portable seabed air curtain device may include a housing 10, an air compressor 20, a compressed air tank 30, an air curtain pipe 40, multiple nozzles 50, a winding assembly 60, a control system, a connecting pipe assembly 70, a valve assembly 80, a pressure detection assembly 90, and a pressure relief assembly 100. The air compressor 20, compressed air tank 30, and retractor assembly 60 are detachably installed inside the housing 10. The air compressor 20, compressed air tank 30, and air curtain duct 40 are sequentially connected via connecting pipe assembly 70. Multiple nozzles 50 are spaced apart on the air curtain duct 40, which is wound around the retractor assembly 60. When the air curtain duct 40 is lowered to the seabed, the retractor assembly 60 can be detached from the housing 10 and placed on the ship's deck for pipe laying. After the air curtain duct 40 is lowered to the seabed, the air compressor 20 is turned on to provide high-pressure gas to the compressed air tank 30. The high-pressure gas is introduced into the air curtain duct 40 and ejected as bubbles by the nozzles 50 to form an air curtain wall. The bubble buoyancy effect and seawater flow field effect intercept jellyfish, plankton, and other marine organisms. The control system is installed on the housing 10 (it can be located externally or internally, depending on the situation) to control the operation of the air compressor 20. A valve assembly 80 is mounted on the connecting pipe assembly 70 and is used to control the flow of gas between the air compressor 20, the compressed air tank 30, and the air curtain pipe 40. A pressure detection assembly 90 is mounted on the compressed air tank 30 and is used to detect the pressure of the gas inside the compressed air tank 30. A pressure relief assembly 100 is mounted on top to prevent the gas pressure inside the compressed air tank 30 from becoming too high; it promptly releases the gas when the pressure becomes too high.

[0020] Continue to refer to Figure 1In some embodiments, the housing 10 may include a housing body 11, at least one door 12 disposed on the housing body 11, and a lighting lamp 15 disposed inside the housing body 11. Opening the door 12 allows the winding assembly 60 to be carried out of the housing 10. In some embodiments, a cooling fan 13 is installed on the housing wall of the housing 10 to exchange the internal air of the housing 10 with the external air, thereby dissipating heat from the air compressor 20. In use, the housing 10 is fixed to the coast with detachable fasteners such as bolts and expansion bolts, and has the ability to withstand typhoons, rain, lightning, and vibrations during transportation and operation.

[0021] The case door 12 includes double doors symmetrically located on both sides of the case body 11 and an inspection door located on the side of the case body 11. The double doors are used for handling the winding assembly 60; the inspection door is used by personnel for maintenance, and the size of the inspection door is smaller than that of the double doors.

[0022] In some embodiments, the container 10 is a shipping container with a length of 6058mm, a width of 2438mm, and a height of 2591mm.

[0023] In some embodiments, the air compressor 20 supplies air at a pressure of 0-10 bar.g.

[0024] Continue to refer to Figure 2 In some embodiments, the air curtain duct 40 includes a first air curtain pipe 41 connected to the compressed air tank 30 and a second air curtain pipe 42 connected to the first air curtain pipe 41, with a nozzle 50 disposed on the second air curtain pipe 42. The first air curtain pipe 41 is located above sea level, and the second air curtain pipe 42 is located below sea level or on the seabed. The air curtain duct 40 is a flexible, pressure-resistant pipe with a diameter of 50 mm. The self-weight of the air curtain duct 40 is greater than the buoyancy of seawater, and it has a self-restraining function, allowing it to sink freely to the seabed and resist the impact of seawater flow, normal operation, and transient compressed air flow. Of course, in other embodiments, the diameter of the air curtain duct 40 is only 10 mm to 80 mm. Compared to rigid pipes in related technologies, using a flexible, pressure-resistant pipe facilitates winding.

[0025] In some embodiments, nozzle 50 may be a conical nozzle, made of materials such as copper alloy or stainless steel. The nozzle orifice of nozzle 50 is 1mm-5mm. The distance between two adjacent nozzles 50 is 100mm-500mm.

[0026] like Figure 1 and Figure 4As shown, in some embodiments, the take-up assembly 60 includes a bracket 61, a take-up reel 62, a manual reel 63, and a motor 64. The take-up reel 62 is rotatably mounted on the bracket 61, and the manual reel 63 is mounted on the take-up reel 62 for manually rotating the take-up reel 62 to house the air curtain duct 40. The motor 64 is mounted on the bracket 61 and connected to the shaft of the take-up reel 62 via a gearbox to drive the take-up reel 63 to rotate and take up the air curtain duct 40.

[0027] The take-up assembly 60 also includes an anti-reverse component, which in some embodiments may be mounted on the take-up reel 62. Of course, the anti-reverse component may also be mounted in the gearbox of the motor 64.

[0028] For example, the anti-reverse mechanism is a ratchet and pawl structure. The winding reel 62 is mounted on the bracket 61 via the ratchet and pawl structure to prevent reverse rotation during the winding reel 62's rotation. Specifically, the ratchet and pawl restrict and adjust the direction of rotation of the winding reel 62. For instance, when the winding reel 62 rotates clockwise to wind up the air curtain pipe 40, the winding reel 62 can only rotate clockwise and cannot rotate counterclockwise. When the winding reel 62 rotates counterclockwise to place the air curtain pipe 40, the direction of the ratchet and pawl's restriction on the rotation of the winding reel 62 needs to be adjusted first, so that the winding reel 62 can rotate counterclockwise. The counterclockwise rotation of the winding reel 62 prevents the air curtain pipe 40 from being unable to rotate clockwise during the process. The ratchet and pawl are not shown in the figure; they are existing technology and can be referenced to the principle of a ratchet wrench.

[0029] Similarly, the anti-reverse component can also be installed inside the gearbox of motor 64 on the same principle as described above, and will not be described in detail here.

[0030] Refer again Figure 4 In some embodiments, the take-up assembly 60 may further include a pipe-laying assembly 65, which includes a lead screw 651, a pipe-laying component 652, and a synchronous connector 653. The lead screw 651 is rotatably mounted on the bracket 61 and parallel to the axis of the take-up reel 62. The synchronous connector 653 is a chain or synchronous belt, etc., which connects the take-up reel 62 to the lead screw 651. The take-up reel 62 drives the lead screw 651 to rotate through the synchronous connector 653. The pipe-laying component 652 is reciprocally movable on the lead screw 651 to neatly arrange the air curtain pipes 40 during the take-up process of the take-up reel 62. Understandably, the take-up reel 62 drives the lead screw 651 to rotate together during rotation, and the pipe-laying component 652 reciprocates on the lead screw 651. While the take-up reel 62 is winding, the pipe-laying component 652 arranges the air curtain pipes 40 sequentially on the take-up reel 62 to achieve orderly pipe winding and even stacking. In other embodiments, a motor may also be provided to drive the lead screw 651 to rotate.

[0031] like Figure 1 and Figure 3As shown, in some embodiments, the connecting pipe assembly 70 may include a first delivery pipe 71, a second delivery pipe 72, and a pipe interface 73; the compressed air tank 30 is connected to the air compressor 20 through the first delivery pipe 71, one end of the second delivery pipe 72 is connected to the compressed air tank 30, and the other end of the second delivery pipe 72 is connected to the air curtain pipe 40 through the pipe interface 73. The pipe interface 73 may be a flange or a quick-connect connector, etc.

[0032] Continue to refer to Figure 3 In some embodiments, the valve assembly 80 may include a first valve 81 disposed on the first delivery pipe 71 and a second valve 82 disposed on the second delivery pipe 72. The first valve 81 blocks and connects the gas flow between the air compressor 20 and the compressed air tank 30, so as to promptly cut off the connection between the air compressor 20 and the compressed air tank 30 in the event of an unexpected situation with the air compressor 20; the second valve 82 blocks and connects the gas flow between the compressed air tank 30 and the air curtain pipe 40, so as to promptly cut off the connection between the compressed air tank 30 and the air curtain pipe 40 in the event of an unexpected situation with the compressed air tank 30.

[0033] Refer again Figure 3 In some embodiments, the pressure detection component 90 may include a detection line 91 connected to the compressed air tank 30, a third valve 92 connected to the detection line 91, and a pressure gauge 93 connected to the detection line 91. The pressure gauge 93 can monitor the air pressure inside the compressed air tank 30 to prevent excessively high air pressure inside the compressed air tank 30, which could cause the compressed air tank 30 to rupture, explode, or other accidents.

[0034] Continue to refer to Figure 3 In some embodiments, the pressure relief assembly 100 further includes a pressure relief pipeline 101 connected to the compressed air tank 30 and a fourth valve 102 for pressure relief connected to the pressure relief pipeline 101. The fourth valve 102 is a safety valve. When the air pressure in the compressed air tank 30 is too high, the valve body inside the safety valve is automatically opened by the air pressure to release air. After the air pressure returns to a safe range, the valve body inside the safety valve automatically closes.

[0035] For reference Figure 2 In some embodiments, this portable underwater air curtain device also includes a counterweight 110. The counterweight 110 is deformable and can be made of materials such as iron chains or metal cables that are resistant to seawater corrosion. The counterweight 110 is installed on the outer surface of the air curtain pipe 40 and arranged parallel to the axis of the air curtain pipe 40. The use of iron chains or metal cables facilitates the winding of the air curtain pipe 40 together with the winding assembly 60. The counterweight 110 and the air curtain pipe 40 do not need to be disassembled, which facilitates the handling of the air curtain pipe 40.

[0036] Of course, in other embodiments, the counterweight 110 may include an installation component and a counterweight block mounted on the air curtain pipe 40 via the installation component, so as to submerge the air curtain pipe 40 into the seabed and restrain it to prevent it from being washed away by seawater and air. The installation component may be a clamp, steel wire rope, etc. The counterweight block may be a cement block, iron block, etc.

[0037] The following section will further explain the portable underwater air curtain device in conjunction with its usage.

[0038] When using the portable underwater air curtain device: the portable underwater air curtain device is delivered to the designated location by a container truck, then the container 10 is fixed to the ground, the container door 12 is opened and the retractable assembly 60 is hoisted to the deck of the transport ship, the retractable assembly 60 is activated to place the air curtain pipe 40, after the air curtain pipe 40 is sunk to the seabed, the air compressor 20 is activated to provide high-pressure gas to the compressed air tank 30, the high-pressure gas is delivered to the air curtain pipe 40 and bubbles are sprayed out by the nozzle 50 to form an air curtain wall.

[0039] During recycling, the winding assembly 60 winds up the air curtain pipe 40. After winding, the winding assembly 60 is hoisted into the housing 10 to complete the recycling work.

[0040] Compared to traditional air curtain devices, this reduces the workload of equipment hoisting, counterweight installation, and personnel diving operations. Installation and connection are convenient and efficient, pipelines do not require underwater maintenance, and routine maintenance can be performed by storing equipment in a dedicated warehouse to avoid corrosion from seawater and salt spray on the seabed and coastline. This reduces the frequency of equipment maintenance, extends equipment lifespan, and lowers maintenance costs.

[0041] It should be noted that, for those skilled in the art, without departing from the concept of this utility model, the above-mentioned technical features can be freely combined, and several modifications and improvements can be made, all of which fall within the protection scope of this utility model.
