Description

Technical Field

[0001] This application relates to the technical field of water conservancy facilities, and in particular to an automatic collector for tidal-powered marine debris. Background Technology

[0002] Marine debris pollution is a significant source of pollution in nearshore waters. Current marine debris collection technologies mainly fall into two categories: active and passive collection. Active collection primarily targets large-scale marine debris collection, while passive collection focuses on smaller areas. In the field of passive collection, existing technologies include floating barriers, conveyor belt collection, and powered floating debris bins.

[0003] Floating barrier interception involves setting up barriers to block marine debris, causing it to accumulate in specific areas for subsequent processing. Conveyor belt collection uses conveyor belts to transport marine debris from the water surface to collection equipment. Powered floating trash cans use electricity to drive the trash can up and down or a water pump to generate suction, attracting surrounding water flow and drawing floating debris into the trash can. After the water flows out of the outlet, the floating debris is intercepted inside the trash can.

[0004] Floating barriers would leave large amounts of trash exposed, resulting in a poor aesthetic. Conveyor belt collection and powered floating trash cans require electric drive equipment or water pumps, and the energy consumption and costs associated with using external power sources over the long term would be significant. Solar power, on the other hand, suffers from issues such as insufficient and unstable power supply, and the need for energy storage devices. Summary of the Invention

[0005] To reduce energy consumption, this application provides a tidal-powered automatic collector for marine debris.

[0006] This application provides a tidal-powered automatic marine debris collector, which adopts the following technical solution:

[0007] A tidal-powered automatic marine debris collector includes:

[0008] A collection bucket has an inlet and a drain outlet on its side, with the drain outlet being lower than the inlet.

[0009] A tide gate is installed at the entrance of the collection tank;

[0010] A gate, movably mounted on the collection tank, is used to open and close the drain outlet; and

[0011] A pontoon, connected to the gate, is configured to move the gate as the external water level rises or falls;

[0012] During high tide, the rising external water level opens the tide gate to expose the inlet, while the floating box rises and drives the gate to close the outlet. During low tide, the tide gate closes, while the floating box descends and drives the gate to open to expose the outlet.

[0013] By employing the above technical solution, the tidal level changes drive the pontoon to move up and down, thereby controlling the opening and closing of the gate and the drain outlet. The inlet is controlled by a tidal gate. During high tide, seawater pushes open the tidal gate, the pontoon rises and closes the drain outlet, and the garbage is carried into the collection bin by the water flow. During low tide, the tidal gate closes, the pontoon sinks and opens the drain outlet, the seawater is discharged from the bin while the garbage is retained. The entire process requires no external energy, relying on tidal energy to achieve automatic garbage collection and temporary storage.

[0014] Optionally, a grating is provided at the drain outlet, and the grating is inclined.

[0015] By adopting the above technical solution, by setting an inclined grating at the drainage outlet, garbage can be intercepted during the drainage process, preventing it from being discharged back into the ocean with the water flow.

[0016] Optionally, the collection bucket has a discharge port on one side, and the collection bucket is hinged to the bottom side of the discharge port with an opening and closing component, which switches between a first state and a second state by rotation.

[0017] Specifically, when the opening and closing component is in the first state, it closes the discharge port; when the opening and closing component is in the second state, it opens the discharge port.

[0018] By adopting the above technical solution, in the collection state, the opening and closing component is in the first state, closing the discharge port. In the cleaning state, the opening and closing component is rotated to the second state, opening the discharge port to facilitate the cleaning of waste inside the bin.

[0019] Optionally, the opening and closing component has a first locking component and a second locking component; when the opening and closing component is in a first state, the first locking component locks the opening and closing component to the collection bucket, while the second locking component unlocks; when the opening and closing component is in a second state, the second locking component locks the opening and closing component to the collection bucket, while the first locking component unlocks.

[0020] Optionally, the collection bucket is rotatably connected to two opposite sides with winding assemblies, and the two winding assemblies have the same filter screen. One set of winding assemblies is set on the opening and closing member and winds up the filter screen, while the other set of winding assemblies unwinds the filter screen.

[0021] When the opening and closing component is in the first state, the filter screen divides the inner cavity of the collection bucket into a first collection cavity and a second collection cavity. The first collection cavity is located above the filter screen, and the second collection cavity is connected to the drain outlet. When the opening and closing component is in the second state, the height of the winding assembly on the opening and closing component is lower than that of the other winding assembly.

[0022] By adopting the above technical solution, during collection, the filter screen intercepts garbage in the first collection chamber, while fine particles and silt pass through the filter screen into the second collection chamber and are discharged through the drain outlet. During cleaning, the tilt angle of the filter screen is adjusted by rotating the opening and closing component and cooperating with the winding assembly to facilitate garbage discharge.

[0023] Optionally, the winding assembly on the opening / closing member is located near the end of the opening / closing member away from its own hinge point.

[0024] By adopting the above technical solution, the winding assembly is set at the end of the opening and closing member away from the hinge point, so that when the opening and closing member rotates to the second state, the position of the winding assembly is lowered, naturally forming an inclined guide surface of the filter screen from high to low.

[0025] Optionally, the winding assembly includes

[0026] The rotating rod is rotatably connected to the collection bucket;

[0027] A one-way component, installed on the collection bucket and cooperating with the rotating rod, allows the rotating rod to rotate in one direction only; and

[0028] A roller, for winding the filter screen, is coaxially and detachably sleeved on the rotating rod.

[0029] By adopting the above technical solution, the one-way component enables the drum to rotate in only one direction, preventing the used filter screen from being rewound.

[0030] Optionally, the one-way component has an elastic part, and the drum needs to overcome the elastic force of the elastic part when it rotates.

[0031] By adopting the above technical solution, an elastic part is set in the unidirectional component, so that the drum needs to overcome a certain elastic force when rotating. This elastic damping makes the winding and unwinding process of the filter screen more controllable and less prone to over-winding.

[0032] Optionally, one end of the rotating rod has a rotating handle, and the rotating handle has a positioning element for positioning the reel relative to the collection bucket.

[0033] By adopting the above technical solution, the positioning component can be used to set the drum to a fixed state or a rotatable state relative to the collection bucket, so as to adapt to different scenario requirements.

[0034] Optionally, the automatic marine debris collector also includes a support block connected to the collection bin, which is used to confine the collection bin to the nearshore waters.

[0035] In summary, this application includes at least one of the following beneficial effects:

[0036] 1. Utilizing tidal energy as a power source, it enables the automatic collection, temporary storage, and drainage of marine debris without requiring external electricity or fuel, thus saving energy, protecting the environment, and reducing operating costs.

[0037] 2. By separating the collection chamber and the drainage chamber with a filter screen, the garbage and silt are initially separated, reducing the cleaning burden. The adjustable tilting filter screen also improves the smoothness and convenience of garbage cleaning. Attached Figure Description

Detailed Implementation

[0048] The following is in conjunction with the appendix Figure 1 To be continued Figure 9 This application will be described in further detail.

[0049] Example 1:

[0050] This application discloses an automatic tidal-powered marine debris collector. (Refer to...) Figure 1 The tidal-powered marine debris automatic collector includes a collection bin 1, and a tide gate 4, a sluice gate 5, a buoy 6, and a support 19 installed on the collection bin 1.

[0051] Reference Figure 1 and Figure 2 The collection bin 1 is hollow inside for holding garbage. The top of the collection bin 1 is closed, and the side wall has an inlet 2 and a drain outlet 3 vertically arranged from top to bottom. The inlet 2 is near the top of the collection bin 1, and the drain outlet 3 is near the bottom of the collection bin 1. The tide gate 4 is plate-shaped and installed at the inlet 2 of the collection bin 1. Specifically, the top of the tide gate 4 is hinged to the top of the inlet 2 by a pin. When not pushed by tidal power, the tide gate 4 naturally droops down under its own weight and closes the inlet 2.

[0052] The collection bucket 1 is equipped with a perforated mesh-like grating 7 at the drain outlet 3. The grating 7 is inclined from top to bottom from the top of the drain outlet 3 toward the inside of the collection bucket 1 to block the garbage in the collection bucket 1, while the fine sand carried in the seawater can be moved out of the collection bucket 1 with the seawater through the grating 7.

[0053] The gate 5 is a vertically extending plate that moves vertically on the bottom plate of the collection tank 1. The vertical movement of the gate 5 opens or closes the drain outlet 3. A float 6 is fixed to the top of the gate 5. The float 6 is a floating material with good buoyancy and can be a hollow plastic box. Furthermore, square travel blocks 20 are fixed to the outer walls at opposite ends of the float 6. Vertically extending travel seats 21 are fixed to the side plates on opposite sides of the collection tank 1. Vertically extending travel grooves 22 are formed on the travel seats 21, but these grooves do not penetrate the upper and lower ends of the travel seats 21. Each travel seat 21 corresponds to a travel block 20, and the travel block 20 slides vertically within the corresponding travel groove 22 to guide the movement of the float 6 and the gate 5.

[0054] The support 19 is fixed to the bottom of the collection bucket 1, and the support 19 is fixed in the nearshore sea area by anchoring or gravity to limit the position of the collection bucket 1, prevent the collection bucket 1 from drifting with the tide, and make the inlet 2 of the collection bucket 1 face the direction of the tide.

[0055] During high tide, the external seawater level gradually rises. When the water level reaches a certain height, the water pressure forces open the tide gate 4, exposing the inlet 2, and marine debris enters the collection bin 1 with the water flow. At the same time, the buoy 6 rises with the water level, causing the gate 5 to move upward and close the drain outlet 3, preventing seawater from flowing into the collection bin 1 from the drain outlet 3.

[0056] At low tide, the external water level drops. The tidal gate 4 closes automatically under gravity, preventing garbage from flowing back. At the same time, the pontoon 6 sinks with the drop in water level, causing the gate 5 to move downwards and opening the drain outlet 3, allowing seawater in the collection bucket 1 to be discharged through the grating 7 and the drain outlet 3, while the garbage is temporarily stored in the collection bucket 1.

[0057] Reference Figure 3 Furthermore, the collection bin 1 is provided with a discharge port 8 on the side opposite to the inlet 2 for cleaning the collected garbage. The bottom of the discharge port 8 of the collection bin 1 is hinged with an opening and closing component 9, which includes a door panel 91 and a side baffle 92. The door panel 91 is square and the opening and closing component 9 is hinged to the collection bin 1 through the door panel 91. There are two side baffles 92, which are fixed to opposite sides of the door panel 91 respectively, and the surface of the side baffles 92 is perpendicular to the door panel 91. The side baffles 92 are used to block the sides of the door panel 91.

[0058] The opening and closing component 9 switches between a first state and a second state by rotation. When the opening and closing component 9 is in the first state, the door panel 91 is in a vertically extended state, at which time the door panel 91 closes the discharge port 8 to prevent the leakage of garbage and seawater from the collection bin 1, while the two side baffles 92 are located in the collection bin 1 and respectively abut against the two opposite inner side walls of the collection bin 1. When the opening and closing component 9 is in the second state, the door panel 91 rotates outward by 90° until the panel is in a horizontally extended state, at which time the door panel 91 opens the discharge port 8 to allow the garbage in the collection bin 1 to be cleaned.

[0059] Furthermore, the opening / closing component 9 is equipped with a first locking component 10 and a second locking component 11. When the opening / closing component 9 is in the first state, the first locking component 10 locks it to the collection bucket 1, and the second locking component 11 is in the unlocked state; when switching to the second state, the second locking component 11 locks it, and the first locking component 10 is in the unlocked state.

[0060] Specifically, the first locking member 10 includes a first base 101 and a first pin 102. The first base 101 is installed on the outer wall of the door panel 91. The first pin 102 slides or is threaded through the first base 101. The outer periphery of the collection bucket 1 has a connecting seat 23 for the first pin 102 to connect. When the opening and closing member 9 is in the first state, the first pin 102 is opposite to the connecting seat 23, so that the first pin 102 can simultaneously insert into the first base 101 and the connecting seat 23 to achieve relative locking between the opening and closing member 9 and the collection bucket 1.

[0061] The second locking member 11 includes a second base 111 and a second pin 112. The second base 111 is installed on the outer wall of the door panel 91. The second pin 112 slides or is threaded through the second base 111. The outer periphery of the collection bucket 1 has a slot 37 for the second pin 112 to be inserted. When the opening and closing member 9 is in the second state, the second pin 112 is opposite to the slot 37, so that the second pin 112 can be inserted into the second base 111 and the slot 37 at the same time to achieve relative locking between the opening and closing member 9 and the collection bucket 1.

[0062] The implementation principle of the tidal-powered automatic marine debris collector in this application embodiment is as follows: when the tide rises, the tide gate 4 opens when the tide level meets the pressure difference or the waves reach a certain impact, and the debris flows into the collection bin 1 with the water flow; at the same time, the float box 6 floats with the water level, driving the gate 5 to close the drain outlet 3 upward.

[0063] At low tide, the external water level drops, and the tide gate 4 closes the inlet 2 under gravity. The buoy 6 sinks, causing the gate 5 to move down and open the outlet 3. Seawater in the bucket is discharged after being filtered by the inclined grid, while garbage is intercepted by the grid and temporarily stored in the bucket. Furthermore, the garbage in the collection bucket 1 can be cleaned by opening and closing the opening and closing mechanism 9 at low tide.

[0064] Example 2:

[0065] The difference between this embodiment and Embodiment 1 is that the automatic marine debris collector also includes a winding assembly and a filter screen 12.

[0066] Reference Figure 4 and Figure 5 Specifically, a cover 24 is installed on each of the opposite sides of the collection bucket 1, with one cover 24 located on the side of the door panel 91 of the opening and closing component 9 away from its hinge point. A winding assembly is rotatably connected to each cover 24, and the two winding assemblies jointly wind the same filter screen 12. The holes in the filter screen 12 are not shown in the figure. One set of winding assemblies is used to wind up the filter screen 12, and the other set is used to unwind the filter screen 12. Both the collection bucket 1 and the door panel 91 of the opening and closing component 9 have clearance holes 25 for the filter screen 12 to enter the collection bucket 1.

[0067] Reference Figure 4 and Figure 5 In this embodiment, the hinge point of the opening / closing member 9 is higher than the inner bottom surface of the collection bucket 1. When the opening / closing member 9 is in the first state, the filter screen 12 divides the inner cavity of the collection bucket 1 into an upper first collection chamber 13 and a lower second collection chamber 14. The second collection chamber 14 is connected to the drain outlet 3. Marine debris is intercepted in the first collection chamber 13, while fine particles and silt can pass through the filter screen 12 into the second collection chamber 14 and be discharged with seawater through the drain outlet 3 at low tide.

[0068] Reference Figure 6 When it is necessary to clean up the garbage, rotate the opening and closing part 9 to the second state. At this time, the position of the winding assembly installed on the opening and closing part 9 is lowered to a position lower than that of the other winding assembly. The filter screen 12 between the two sets of winding assemblies is straightened, so that the filter screen 12 is adjusted to a state that gradually tilts downward along the direction close to the opening and closing part 9, so as to facilitate the discharge of garbage. By winding and unwinding the filter screen 12, the garbage on the filter screen 12 can move in the direction of moving out of the collection bucket 1, improving the convenience of removing garbage.

[0069] Reference Figure 7 , Figure 8 and Figure 9Each winding assembly includes a rotating rod 15, a one-way component 16, and a drum 17. The rotating rod 15 includes a rotating cylinder 151 and a rotating handle 152. The rotating cylinder 151 is rotatably connected to the housing 24, and the rotating handle 152 is in the shape of a handwheel and is fixedly sleeved on the end of the rotating cylinder 151, with the rotating handle 152 located in the external environment of the housing 24. The rotating cylinder 151 is cylindrical and rotatably connected to the housing 24. One-way component 16 is installed in housing 24 and located in rotating cylinder 151. One-way component 16 includes a main shaft 161, a pawl 162, and an elastic part 163. The main shaft 161 is fixed to housing 24 and includes a first section 1611 and a second section 1612 coaxially fixed. The outer diameter of the first section 1611 is larger than the outer diameter of the second section 1612. The main shaft 161 is coaxially disposed in the inner cavity of rotating cylinder 151, and rotating cylinder 151 is rotatably sleeved on the outer circumference of the first section 1611. There is a gap between the inner circumference of rotating cylinder 151 and the outer circumference of second section 1612. Pawl 162 is hinged to the second section 1612 of main shaft 161. The elastic part 163 is a spring and also connects pawl 162 and main shaft 161, giving pawl 162 a tendency to rotate outward from main shaft 161.

[0070] More specifically, one end of the second segment 1612 and one end of the rotating cylinder 151 both protrude from one end of the cover 24, and one end of the second segment 1612 extends beyond the end of the rotating cylinder 151 and is fixed with a fixing seat 26. The fixing seat 26 is L-shaped and fixed to the outer peripheral wall of the cover 24, so that the main shaft 161 is fixed to the cover 24. The fixing seat 26 also forms a clearance cavity 27 for the rotating handle 152 to pass through when rotating, so that the operator can drive the rotating rod 15 to rotate from the external environment by rotating the handle 152.

[0071] Reference Figure 8 In this design, the inner circumference of the rotating cylinder 151, which is opposite to the second section 1612, is fixed with ratchet teeth 28 evenly spaced along its circumference. The ratchet teeth 28 have a stop surface 29 and a guide surface 30. When the rotating cylinder 151 rotates in the design direction, the guide surface 30 presses down on the pawl 162 and overcomes the elastic force of the elastic part 163. When the rotating cylinder 151 rotates in the opposite direction in the design direction, the stop surface 29 abuts against the pawl 162, thereby restricting the rotation of the rotating cylinder 151. This allows the rotating cylinder 151 to rotate only in one direction in the design direction. That is, the rotating cylinder 151 located on the opening and closing member 9 rotates only in one direction in the winding direction, and the rotating cylinder 151 located on the side of the collecting bucket 1 away from the opening and closing member 9 rotates only in one direction in the unwinding direction. The elastic part 163 provides a certain damping for the rotation of the rotating cylinder 151.

[0072] Reference Figure 8 and Figure 9The drum 17 is cylindrical, and one end of the filter screen 12 is fixed to the drum 17 and wound around the drum 17. A limiting strip 31 protruding from the inner circumference of the drum 17 is fixedly embedded in the drum 17. A limiting groove 32 is opened on the outer circumference of the rotating drum 151 along the axial direction of the rotating drum 151 for the limiting strip 31 to abut. The drum 17 is coaxially sleeved on the rotating drum 151 through the cooperation of the limiting strip 31 and the limiting groove 32, so that when the rotating drum 151 rotates, it drives the drum 17 to rotate together to wind or unwind the filter screen 12.

[0073] Reference Figure 5 and Figure 6 After cleaning the garbage in collection bucket 1, the filter screen 12 in collection bucket 1 is adjusted to be far away from the bottom of collection bucket 1. When the tide rises and seawater is swept into collection bucket 1 by the waves, the impact force of the water flow gives the filter screen 12 a downward force, and the weight change of the garbage sinking on the filter screen 12 can cause the filter screen 12 to gradually unroll, so that the length of the filter screen 12 in collection bucket 1 changes, which will cause the garbage on the filter screen 12 to be disturbed, which is conducive to further filtration of fine sand.

[0074] Reference Figure 7 Furthermore, a positioning element 18 is also installed on the rotating handle 152. The positioning element 18 can position the rotating handle 152 relative to the cover 24 so that the winding assembly can switch between positioning and rotation with a certain damping as needed. For example, when the opening and closing element 9 is in the second state and the filter screen 12 needs to be straightened into an inclined state, the winding assembly used for unwinding is adjusted to the positioning state, and then the winding assembly used for winding is rotated to wind up, so that the filter screen 12 between the two sets of winding assemblies can be straightened.

[0075] Specifically, the positioning element 18 is a bolt, and the rotating handle 152 is threaded through the positioning element 18 along the axis of the parallel rotating cylinder 151. A plurality of positioning slots 38 for the positioning element 18 to be inserted are evenly spaced on the outer peripheral wall of the cover 24 along the circumference of the rotating cylinder 151. The positioning element 18 can restrict the rotation of the rotating rod 15 by moving into the positioning slot 38.

[0076] Reference Figure 7 and Figure 8 Furthermore, each cover 24 is equipped with two rollers 33 coaxial with the rotating cylinder 151. The rollers 33 can be rotatably connected or fixedly connected to the cover 24. The filter screen 12 passes between the two rollers 33 and enters the collection bucket 1. The rollers 33 flatten the filter screen 12.

[0077] Reference Figure 4 and Figure 9In addition, to facilitate the replacement of the roll 17 and the filter screen 12 together after the entire roll of filter screen 12 has been used, the end of the cover 24 away from the rotating handle 152 is a first side plate 34. The first side plate 34 is pressed against the main body of the cover 24. The ends of the roller shaft 33 and the second section 1612 of the main shaft 161 away from the first section 1611 are slidably inserted through the first side plate 34 and locked with nuts to prevent the first side plate 34 from detaching from the cover 24. When the nuts are removed, the first side plate 34 can be disassembled, exposing the inner cavity of the cover 24, and the roll 17 can be coaxially sleeved on the rotating rod 15 or removed from the rotating rod 15.

[0078] Reference Figure 4 and Figure 6 Furthermore, the side plate on the same side as the first side plate 34 of the collection tank 1 is the second side plate 35. The main body of the collection tank 1 has a stud that passes through the second side plate 35. A nut is threaded on the stud to press the second side plate 35 against the main body of the collection tank 1. Removing the nut allows the second side plate 35 to be removed from the collection tank 1, thus exposing this side of the collection tank 1. A clearance hole 25 passes through the side of the collection tank 1 closest to the second side plate 35. The side baffle 92 of the opening / closing member 9 has a disassembly hole 36 for removing the filter screen 12.

[0079] After removing both the first side plate 34 and the second side plate 35, the rollers 17 and the filter screens 12 on the two sets of winding assemblies can be removed and replaced together, and the inside of the collection bucket 1 can be further cleaned.

[0080] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
