Description

Technical Field

[0001] This invention relates to the field of marine microplastic collection technology, specifically to a marine microplastic collector that is easy to adjust in depth. Background Technology

[0002] With the development of society, people are generating more and more garbage. When people play at the beach, they carelessly discard some personal packaging, which is then swept into the sea by the waves. When these microplastics float in the ocean, they are accidentally ingested by marine life, causing serious damage to marine life. In order to reduce the damage to marine life, marine microplastic collectors are needed to collect microplastics floating in the ocean, thereby protecting marine life.

[0003] Referring to a marine microplastic water sampling device disclosed in CN113218715A, the device slowly releases a tow rope from a ship, causing it to sink under its own weight. Once the vertical cylinder reaches a designated depth, external water pressure overcomes the force of the upper compression spring, pushing the upper piston downwards. This moves the upper piston below the vertical upper valve sleeve, allowing water samples at the designated depth to enter the vertical cylinder through the valve sleeve, thus collecting the sample. Simultaneously, as the upper piston moves below the valve sleeve, external water pressure enters the vertical cylinder and acts on a floating piston, overcoming the force of the lower compression spring and causing the floating piston to move downwards. During the downward movement, when the floating sleeve moves below the radial limiting rod, the radial limiting rod moves into the vertical cylinder under the action of the side compression spring. After the outer end of the radial limiting rod moves into the radial guide hole, the counterweight sleeve will fall along the vertical cylinder under its own weight. At this time, the vertical cylinder will float upward under the buoyancy of the float. When the vertical cylinder floats above the designated depth, the valve stem will move upward again under the action of the upper compression spring, causing the upper piston to move into the sealing vertical upper valve sleeve and seal the vertical upper valve sleeve to prevent water samples above the designated depth from entering the vertical cylinder. After that, the marine microplastic water sampling device floats to the sea surface under the action of buoyancy to complete the water sample collection at the designated depth. However, the following problems still exist:

[0004] In actual use of the above-mentioned device, although the depth of the sampling device is adjusted by controlling the traction rope, the traction rope needs to be controlled by a boat during adjustment. The raising and lowering of the sampling device is controlled by raising and lowering the traction rope, which leads to errors in the sampling device during sampling, thereby reducing the sampling effect.

[0005] Referring to the submerged microplastic collector disclosed in CN115290392A, it consists of a housing and connecting blocks. The housing has connecting blocks symmetrically connected to both sides of its top. It also includes a transmission door, a protective barrel, a limiting barrel, a collection barrel, a drain pipe, a torsion spring, a rope winding machine, a pull rope, a pumping mechanism, and a bottling mechanism. The transmission door is rotatably connected to the front left side of the housing. The bottom of the housing is connected to a protective barrel, inside which is connected a limiting barrel. A collection barrel for collecting microplastics from seawater is slidably connected inside the limiting barrel. The collection barrel has inlets on both the front and rear sides of its upper part. Drain pipes are rotatably connected to both sides of the lower part of the collection barrel. The opposite sides of the left-side drain pipe are connected to the collection barrel by torsion springs, and the opposite sides of the right-side drain pipe are connected to... A torsion spring connects the collection buckets. A rope winding machine is installed in the middle of the top of the container. Each of the two winding reels of the machine has a rope for pulling the collection buckets up. One end of each rope is connected to one of the two winding reels, and the other end is connected to the collection bucket. Pumping mechanisms are located on the left and right sides of the lower part of the container to extract microplastics from the seawater. Inside the container is a bottling mechanism to collect the microplastics from the collected seawater. This allows for rapid pumping of seawater into the collection buckets, ensuring efficiency. Simultaneously, the pumping mechanism filters out objects larger than microplastics during the pumping process, preventing fish or other objects from being drawn into the collection buckets and affecting subsequent microplastic testing. However, the following problems still exist:

[0006] In actual use of the above-mentioned device, although microplastics are collected by the collection tube, the collection tube needs to be emptied after collecting the microplastics in order to discharge the microplastics inside the collection tube. The connection between the collection tube and the device is relatively complicated, which makes it inconvenient to discharge the microplastics later.

[0007] Therefore, we propose a marine microplastic collector that is easy to adjust in depth in order to solve the problems mentioned above. Summary of the Invention

[0008] The purpose of this invention is to provide a marine microplastic sampler that is easy to adjust in depth, in order to solve the problems mentioned in the background art. Currently, the sampling device in the market requires a boat to control the tow rope, and the raising and lowering of the sampling device is controlled by raising and lowering the tow rope. This results in errors during sampling, and the connection between the sampling tube and the device is relatively complicated, which makes it inconvenient for the subsequent discharge of microplastics.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a marine microplastic collector that is easy to adjust in depth, comprising a float and buoys, wherein buoys are fixed at both ends of the float;

[0010] Also includes:

[0011] A warning light is fixed to the top of the float with screws, and the warning light is connected to the battery via a wiring harness. A fixing rod is fixed to the bottom of the float with screws, a sliding plate slides on the fixing rod, and the collector body is installed at the bottom of the sliding plate.

[0012] Preferably, the float has a rotating rod inside, and the left end of the rotating rod is connected to the output end of the motor. A winding roller is keyed to the middle of the rotating rod. A pull rope is wound on the winding roller, and the other end of the pull rope extends out of the float and is connected to the top of the sliding plate.

[0013] With the above structural design, the rotating rod can rotate and drive the sliding plate to move via the take-up roller.

[0014] Preferably, the bottom opening of the collector body is rotatably provided with a baffle, and the collector body is provided with a mesh, and the bottom of the collector body is provided with an impeller, the left end of which is connected to the bottom of the driven rod through a bevel gear set.

[0015] The above-described structure allows the flow of seawater to drive the impeller to rotate.

[0016] Preferably, the driven rod is rotatably disposed inside the collector body, and an auger is fixed to the top of the driven rod, while the bottom of the auger is rotatably disposed inside the collector body.

[0017] The above structural design allows for the unified collection of microplastics inside the collector body.

[0018] Preferably, a telescopic rod is fixed to the right end of the rotating rod, and the telescopic rod is rotatably disposed inside the float plate. The right end of the telescopic rod extends into and engages with the left end of the worm gear, and the right end of the worm gear is rotatably disposed inside the float plate.

[0019] The above structural design allows the telescopic rod to be disconnected from or connected to the worm gear.

[0020] Preferably, the front end of the worm gear is engaged with a worm wheel, and the middle part of the worm wheel is keyed to a solar panel. The top of the solar panel extends out of the interior of the floating plate, and the solar panel is connected to a battery via a wiring harness.

[0021] The above structural design allows the solar panel to rotate stably.

[0022] Preferably, the top of the collector body is slidably engaged with a locking block, and the top of the outer end of the locking block is arc-shaped.

[0023] The above structural design allows the card block to move after being squeezed by force.

[0024] Preferably, the inner end of the card block is connected to a spring, and the other end of the spring is connected to the inside of the collector body.

[0025] The above structural design allows the spring to limit the movement of the locking block.

[0026] Preferably, the outer end of the locking block is attached between the limiting rod and the slider, and the top of the limiting rod is fixed inside the sliding plate. The slider slides through the limiting rod, the outer end of the slider is slidably engaged inside the sliding plate, and the inner end of the slider is triangularly shaped.

[0027] The above structural design allows the slider to move when compressed.

[0028] Compared with existing technologies, the beneficial effects of this invention are: this easily adjustable-depth marine microplastic collector can accurately adjust the depth, quickly discharge microplastics, and is energy-saving and environmentally friendly. Through the rotation of the winding roller, the sliding plate slides on the fixed rod, allowing the collector body to be accurately moved to the correct position. The movement of the locking block allows the sliding plate to quickly detach from the collector body, enabling the collector body to quickly dump the microplastics. Furthermore, the rotation of the solar panel allows it to rotate according to the sun's position, providing electricity to the device and achieving energy conservation and environmental protection. The specific details are as follows:

[0029] (1) A take-up roller is provided. The output end of the motor rotates to drive the rotating rod to rotate, which in turn drives the take-up roller to rotate, which in turn enables the take-up roller to take up the pull rope, thereby enabling the pull rope to drive the collector body to move, and thus enabling the collector body to make accurate movement adjustment according to the required depth, thereby improving the accuracy of microplastic collection.

[0030] (2) A locking block is provided. By pressing the collector body, the collector body pushes the locking block to move inside the sliding plate, thereby causing the locking block to disengage from the limit rod and the slider, so that the collector body can disengage from the sliding plate, and the micro-plastics inside the collector body can be quickly poured out, thereby improving efficiency.

[0031] (3) A solar panel is installed. By moving the telescopic rod, the rotating rod rotates, which in turn drives the worm gear to rotate. The worm gear then drives the worm wheel to rotate, which in turn drives the solar panel to rotate. This allows the solar panel to adjust according to the direction of the sun, thus enabling the solar panel to supply power to the equipment inside the device, thereby achieving the purpose of energy saving and environmental protection.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1-8This invention provides a technical solution: a marine microplastic collector with adjustable depth, comprising a float 1 and floats 2, with floats 2 fixed at both ends of the float 1; further comprising: a warning light 3 fixed to the top of the float 1 by screws, the warning light 3 being connected to a battery via a wiring harness; a fixing rod 8 fixed to the bottom of the float 1 by screws, a sliding plate 7 sliding on the fixing rod 8, and a collector body 9 disposed at the bottom of the sliding plate 7; a rotating rod 4 rotating inside the float 1, the left end of the rotating rod 4 being connected to the output end of a motor, and a key connecting the middle of the rotating rod 4 to... A take-up roller 5 is wound with a pull rope 6, and the other end of the pull rope 6 extends out of the interior of the float plate 1 and is connected to the top of the sliding plate 7. A baffle 10 is rotatably provided at the bottom opening of the collector body 9, and a mesh is provided on the collector body 9. An impeller 11 is rotatably provided at the bottom of the collector body 9. The left end of the impeller 11 is connected to the bottom of the driven rod 13 through a bevel gear set 12. The driven rod 13 is rotatably provided inside the collector body 9, and an auger 14 is fixed at the top of the driven rod 13. The bottom of the auger 14 is rotatably provided inside the collector body 9.

[0043] refer to Figure 1 , Figure 2 , Figure 6 and Figure 8 When the depth of the collector body 9 needs to be adjusted, the motor is powered by the battery, enabling the motor to operate. Pressing the motor output terminal rotates the rotating rod 4, which in turn rotates the take-up roller 5, which in turn moves the pull rope 6. By rotating the take-up roller 5 in both directions, the pull rope 6 can move the sliding plate 7, which can then move on the fixed rod 8. This movement of the sliding plate 7 moves the collector body 9, allowing it to be adjusted according to different depths. The flow of seawater then moves the microplastics, which in turn pushes against the baffle 10, allowing the microplastics to enter the collector body 9. The baffle 10 prevents the microplastics from flowing out of the collector body 9, while the seawater flows through the mesh on the collector body 9, thus achieving the purpose of collecting microplastics.

[0044] A telescopic rod 15 is fixed to the right end of the rotating rod 4, and the telescopic rod 15 is rotatably set inside the floating plate 1. The right end of the telescopic rod 15 extends into and engages with the left end of the worm gear 16. The right end of the worm gear 16 is rotatably set inside the floating plate 1. The front end of the worm gear 16 is engaged with a worm wheel 17, and the middle part of the worm wheel 17 is keyed to a solar panel 18. The top of the solar panel 18 extends out of the floating plate 1. The solar panel 18 is connected to a battery through a wiring harness. A locking block 19 is slidably engaged at the top of the collector body 9. The top of the outer end of the locking block 19 is arc-shaped. A spring 20 is connected to the inner end of the locking block 19. The other end of the spring 20 is connected to the inside of the collector body 9. The outer end of the locking block 19 is attached between the limiting rod 21 and the slider 22. The top of the limiting rod 21 is fixed inside the sliding plate 7. A slider 22 slides through the limiting rod 21. The outer end of the slider 22 is slidably engaged inside the sliding plate 7. The inner end of the slider 22 is triangular.

[0045] refer to Figures 1 to 5 and Figure 7The flow of seawater drives the impeller 11 to rotate, which in turn drives the bevel gear set 12 to rotate. This, in turn, drives the driven rod 13 to rotate, which in turn drives the auger 14 to rotate. This causes the microplastics at the bottom of the collector body 9 to be transported to the top of the collector body 9 via the rotation of the auger 14. The microplastics are then stored at the top of the collector body 9. When it is necessary to remove the microplastics from inside the collector body 9, pressing the collector body 9 causes the top of the collector body 9 to move inside the sliding plate 7. This causes the locking block 19 to contract under pressure, moving it further inside the collector body 9. This movement compresses the spring 20, disengaging the locking block 19 from the engagement between the limiting rod 21 and the slider 22, allowing the locking block 19 to move to the top of the slider 22. Then, by using the inclined surface of slider 22, the bottom of slider 22 is made to fit against the top of limit rod 21, thereby allowing the locking block 19 to disengage from limit rod 21 and slider 22. This allows the collector body 9 to detach from the inside of sliding plate 7, enabling the rapid removal of microplastics. The collector body 9 can then float on the sea surface via float plate 1 and float ball 2, allowing it to be stably placed into the sea. The movement of telescopic rod 15 causes it to engage with worm gear 16, causing rotating rod 4 to rotate and drive worm gear 16 to rotate. This, in turn, drives worm wheel 17 to rotate, which in turn drives solar panel 18 to rotate. Solar panel 18 then rotates according to the sun's position, converting solar energy into electrical energy which is transmitted to the battery. The battery provides power, and the warning light 3 alerts passing ships, achieving energy conservation and environmental protection, thus completing a series of tasks.

[0046] The working principle of this embodiment is as follows: When using this marine microplastic collector that is easy to adjust in depth, firstly, refer to... Figure 1 , Figure 2 , Figure 6 and Figure 8When the depth of the collector body 9 needs to be adjusted, the motor is powered by the battery, enabling the motor to operate. Pressing the motor output terminal rotates the rotating rod 4, and the forward and reverse rotation of the winding roller 5 causes the pull rope 6 to move the sliding plate 7, which in turn moves on the fixed rod 8. Then, the flow of seawater moves the microplastics, which pushes the baffle 10, allowing the microplastics to enter the interior of the collector body 9. The baffle 10 prevents the microplastics from flowing out of the collector body 9, while the seawater flows through the mesh on the collector body 9, thus achieving the purpose of collecting microplastics.

[0047] refer to Figures 1 to 5 and Figure 7 The flow of seawater drives the impeller 11 to rotate, which in turn drives the bevel gear set 12 to rotate, which in turn drives the driven rod 13 to rotate, which in turn drives the auger 14 to rotate. The microplastics are then stored at the top of the collector body 9. When it is necessary to remove the microplastics from inside the collector body 9, pressing the collector body 9 causes the locking block 19 to move into the collector body 9, which compresses the spring 20. This causes the locking block 19 to move to the top of the slider 22, allowing it to disengage from the limit rod 21 and the slider 22. The block then floats on the sea surface via the float plate 1 and the buoy 2, causing the rotating rod 4 to rotate, which in turn drives the worm gear 16 to rotate, which in turn drives the worm wheel 17 to rotate, which in turn drives the solar panel 18 to rotate. This allows the solar panel 18 to convert solar energy into electrical energy and transmit it to the battery. The warning light 3 can then be used to warn passing ships, thus achieving the goal of energy conservation and environmental protection, and completing a series of tasks.
