DETAILED DESCRIPTION OF THE INVENTION

[0012] The following description provides many different embodiments or examples for implementing different features of the present disclosure. The terms "first," "second," and other hierarchical terms used in the present specification and claims do not themselves imply a priority, precedence, or order of an element relative to other elements, but are merely used as labels to distinguish an element from other elements having the same name. Thus, a first element in the specification may be referred to as a second element in a claim. Furthermore, similar and / or corresponding symbols may be used repeatedly in different embodiments of the present disclosure. These similar and / or corresponding symbols or letters are used to clearly describe several embodiments of the present disclosure and do not dictate a relationship between different embodiments and / or structures.

[0013] Spatially relative terms, such as "above," may be used herein to describe the relationship of one element or feature to another element or feature as illustrated in the figures for ease of description. Spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. The device may be in other orientations (rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein may likewise be interpreted accordingly. If the device in the figures were turned upside down, the elements at "above" would become the elements at "below."

[0014] As used herein, terms such as "comprises," "has," and the like should be interpreted to mean "including, but not limited to." Thus, when terms such as "comprises," "has," and the like are used in describing the present disclosure, they specify the presence of the corresponding features, regions, steps, operations, and / or components, and do not exclude the presence of one or more other features, regions, steps, operations, and / or components. Furthermore, deviations between any two numerical values ​​or directions may exist.

[0015] A waste collection device 100 suitable for floating on water is provided. The collected waste may include any trash, debris, or sludge. The collected waste may also be solid waste, liquid waste, or semi-solid waste such as plastic or oil spills. See FIGS. 1 and 2. The waste collection device 100 includes a floating device 200 and a waste collection device 300 coupled to the floating device 200. The floating device 200 includes a plurality of floating units 210. Each floating unit 210 includes a base 211 and a pillar 212 connected to the base 211. The pillar 212 is connected to the top of the base 211, with the entire base 211 and a portion of the pillar 212 below the water surface. It should be noted that the floating device 200 may be any device capable of floating on water. In some embodiments, the floating device 200 is a boat. In some embodiments, the waste collection device 300 represents the space formed between the floating units 210. The space is used to collect and store waste. In some embodiments, the waste collection device 300 has an element adjacent to the flotation unit 210, and the element is specifically used to collect and store waste.

[0016] The waste collection apparatus 100 may sway up and down. To prevent the waste collection apparatus 100 from capsizing, the water level is designed to be within a certain range of the height of the waste collection apparatus 100. To ensure that the water level is within the certain range of the height of the waste collection apparatus 100, the density of the base 211 is greater than the density of the pillars 212, which makes the center of gravity of the waste collection apparatus 100 relatively low and stabilizes the waste collection apparatus 100. For example, the center of gravity 210C of each flotation unit 210 is located below the water level in most cases.

[0017] 3A and 3B. In some embodiments, the base 211 and the pillars 212 comprise steel, aluminum, concrete, reinforced concrete (RC), steel reinforced concrete, fiber reinforced plastic (FRP), or a combination thereof. In some embodiments, the base 211 and the pillars 212 are manufactured in the same process and integrally formed. In some embodiments, the base 211 and the pillars 212 are manufactured separately and then assembled together.

[0018] In some embodiments, the base 211 is solid and the pillars 212 are hollow, so that the density of the base 211 is greater than the density of the pillars 212 (according to the formula: ρ=m / v), but the structures of the base 211 and the pillars 212 are not limited thereto. In some embodiments, the base 211 may have a plate-like structure, and the pillars 212 may be cylindrical. In some embodiments, the base 211 is replaced by a metal chain fixed to the pillars 212. In some embodiments, the plate-like base 211 includes a sloping peripheral portion extending downward. In some embodiments, the base 211 and / or the pillars 212 have a balance element 215. The balance element 215 helps to balance the floating unit 210 in water. In some embodiments, the balance element 215 extends around the base 211 and / or the pillars 212. In some embodiments, the balance element 215 is a fin. In some embodiments, the balancing element 215 may be referred to as a "bilge keel."

[0019] In some embodiments, the diameter D1 of the base 211 is larger than the diameter D2 of the pillar 212. In some embodiments, the diameter D1 of the base 211 is between about 5.0 m and about 7.0 m, for example, 6.0 m. In some embodiments, the diameter D2 of the pillar 212 is between about 3.0 m and about 5.0 m, for example, 4.0 m. In some embodiments, the height H of each flotation unit 210 is between about 6.0 m and about 9.0 m, for example, 7.0 m or 8.0 m. In some embodiments, the distance between adjacent bases 211 on the long sides of the waste collection apparatus 100 is between 0.5 m and 4.0 m, for example, 1.0 m, 2.0 m, or 3.0 m. In some embodiments, the distance between adjacent bases 211 on the short sides of the waste collection apparatus 100 is between 1.0 m and 5.0 m, for example, 2.0 m or 4.0 m.

[0020] In some embodiments, the floating device 200 includes a waterproof element 213 located at the connection between the pillar 212 and the base 211. The waterproof element 213 includes silicone. Note that although the waterproof element 213 is shown attached to the outer surface of the pillar 212 (e.g., by a coating) in FIG. 3A , the waterproof element 213 may also be attached to the inner surface of the pillar 212. In some embodiments, the amount of waterproof element 213 attached to the outer surface of the pillar 212 is greater than the amount of waterproof element 213 attached to the inner surface of the pillar 212. In some embodiments, the floating device 200 includes a bulk element 214 attached to the inside of the pillar 212. The bulk element 214 includes expanded polystyrene (EPS), expanded polypropylene (EPP), or the like. Because the density of the bulk element 214 is relatively low, the weight of the entire floating unit 210 does not change significantly. The volume of the bulk element 214 is substantially the same as the internal volume of the pillar 212. The waterproof element 213 and the bulk element 214 can prevent water from entering the inside of the floating unit 210. Therefore, the life of the floating unit 210 is extended.

[0021] In some embodiments, there is a weight variation between different flotation units 210. Thus, in some embodiments, a flotation unit 210 that is lighter than the flotation unit 210 has a counterweight (not shown) installed within the pillar 212 or within the base 211. The counterweight may be made of concrete or metal. In concrete embodiments, the counterweight may be poured directly into the pillar 212 or may be integrally molded. In metal embodiments, the counterweight may be formed as a single piece. In some embodiments, the single-piece counterweight is attached to the pillar 212 or the base 211 with an adhesive material. In some embodiments, the single-piece counterweight is installed in a receiving portion (e.g., a groove or recess) formed on the corresponding flotation unit 210, for example, the receiving portion is formed on the top surface of the base 211 or within the pillar 212. The counterweight can increase the stability of the waste collection apparatus 100.

[0022] Because each flotation unit 210 is manufactured using the same process, standardization of the manufacturing of the flotation units 210 ensures the stability of the waste collection device 100. In addition, manufacturing costs are reduced through standardization.

[0023] Different methods are used to connect the flotation units 210 to each other. See Figure 4. In some embodiments, the flotation device 200 has a frame 220 and a plurality of fastening elements 230. The frame 220 and the fastening elements 230 are used to connect the flotation units 210 to each other.

[0024] The frame 220 comprises a metal, such as aluminum or iron. The frame 220 is formed by welding. For example, the frame 220 is a skeleton frame, and a different number of columns are connected to each other by welding. The frame 220 is treated to prevent corrosion. In some embodiments, the frame 220 is a grid structure having a plurality of hollow portions 221. In some embodiments, the hollow portions 221 are filled with a material, such as expanded polystyrene (EPS) or expanded polypropylene (EPP), so that the frame 220 is cubic. In some embodiments, some hollow portions 221 are filled with a material, while others are not.

[0025] In some embodiments, the waste collection apparatus 100 includes a power supply unit 400 that provides power to the waste collection apparatus 100 or the building 500 (described below), and the power supply unit 400 is installed in one of the hollow portions 221 of the grid structure. For example, the power supply unit 400 is a battery that can generate power and is electrically connected to the floating unit 210 to provide power to the waste collection apparatus 100 or the building 500. Other elements may also be installed in the hollow portion 221.

[0026] The fastening elements 230 may be bolts, screws, etc. The frame 220 is connected to the floating unit 210 by the fastening elements 230. In some embodiments, the frame 220 contacts the top surfaces of the pillars 212. For simplicity, only a portion of the fastening elements 230 are shown in FIG. 4 , but other fastening elements 230 may be present on the remainder of the floating unit 210.

[0027] Referring now to FIG. 5, in addition to the frame 220, the flotation device 200 further includes a reinforcing frame 240. The reinforcing frame 240 is made of the same material as the frame 220. The reinforcing frame 240 strengthens the connection between the flotation units 210. In some embodiments, the reinforcing frame 240 contacts the outer surfaces of the pillars 212 and the top surface of the base 211 (shown in FIG. 5). For simplicity, only one fastening element 230 is shown in FIG. 5, but other fastening elements 230 may be present on the remainder of the flotation unit 210.

[0028] It should be noted that the arrangement and number of the flotation units 210 are not limited thereto. Referring to FIG. 6 , other waste collection apparatuses 100A having different numbers of flotation units 210 are shown. Because the numbers of the flotation units 210 are different, the frames 220A used to connect the flotation units 210 to each other also have different structures. The arrangement and number of the flotation units 210 can be adjusted as needed. For example, the flotation units 210 of the waste collection apparatus 100 and the flotation units 210 of the waste collection apparatus 100A are installed symmetrically, but in other embodiments, the flotation units 210 are installed asymmetrically. For example, if a larger space is required for collecting waste, some of the flotation units 210 can be omitted.

[0029] 7A and 7B. In some embodiments, the waste collection device 300 includes a suspension unit 310, a waste bag 320 coupled to the suspension unit 310, and a waste container 330 disposed between a portion of the floating unit 210. The suspension unit 310 is disposed above the frame 220. The suspension unit 310 includes a support stand 311, a motor, and a suspension assembly connected to the motor's rotation shaft and the waste bag 320. The waste bag 320 has an opening 321, and the orientation of the opening 321 can be varied according to actual needs (e.g., as shown in FIG. 19). The waste bag 320 is moved up and down by the suspension unit 310. Specifically, due to the movement (e.g., rotation) of the motor, the suspension assembly is driven to lift the waste bag 320. In some embodiments, the waste bag 320 moves up and down through at least one hollow portion 221 of the frame 220. Specifically, in FIG. 7A, waste bag 320 is positioned in waste container 330, and in FIG. 7B, waste bag 320 is removed from waste container 330.

[0030] Waste bag 320 is formed of a flexible material. When waste bag 320 is placed in waste container 330, waste bag 320 is compressed to hold it in place. In some embodiments, an attachment element made of a material whose density is greater than that of water is attached to waste bag 320 and closes to opening 321 so that waste bag 320 is flat against the bottom of waste container 330. In some embodiments, waste container 330 has multiple side walls 331, 332, and 333, and side wall 332 has multiple perforations. Thus, when waste accumulates in waste container 330, water can flow through the perforations to side wall 332 and allow waste to enter waste container 330.

[0031] In some embodiments, the waste collection device 100 includes a sensing device (not shown) that senses the amount of collected waste and / or a control device (not shown) coupled to the sensing device. In some embodiments, when the sensing device detects that the amount of collected waste in the waste bag 320 is nearly full, a signal is sent to the control device, and an operator decides whether to remove the waste bag 320 from the waste container 330. In some embodiments, when the sensing device detects that the amount of collected waste in the waste bag 320 is nearly full, a signal is sent to the suspension unit 310, and the suspension unit 310 can directly remove the waste bag 320 from the waste container 330. In some embodiments, the signal is a message displayed on the control device. In some embodiments, the sensing device is a camera, and an image of the amount of collected waste in the waste bag 320 is sent to the control device, and an operator decides whether to remove the waste bag 320 from the waste container 330 according to the display on the control device. In embodiments where a waste bag 320 is provided, the waste bag 320 is tied off so that the waste does not spill after it is removed from the waste container 330. Alternatively, the waste bag 320 may be transported to a recycling plant.

[0032] 8A and 8B. In some embodiments, the waste collection apparatus 300 includes a suspension unit 310, a waste container 330A coupled to the suspension unit 310, and an inlet unit 340. Specifically, in FIG. 8A, the waste container 330A corresponds to the inlet unit 340, and in FIG. 8B, the waste container 330A moves up and no longer corresponds to the inlet unit 340. The waste container 330A is moved up and down by the suspension unit 310. The inlet unit 340 has multiple walls, forming a flow path between them. In some embodiments, multiple blades are installed in the inlet unit 340 to form the flow path. The waste container 330A is located at the end of the flow path and collects waste passing through the flow path. Rotation of the blades generates more water flow, allowing more waste to enter the waste collection apparatus 100. In some embodiments, the blades are rotatable around a rotation axis, and the water flow direction is different from the rotation axis. For example, the direction of water flow is perpendicular to the axis of rotation about which the blades rotate. Waste container 330A is similar to waste container 330. In some embodiments, waste containers 330A and 330B do not have holes formed on at least one sidewall. It should be noted that waste container 330 can also be used in the embodiments shown in FIGS. 8A and 8B. Similarly, waste collection device 100 includes a sensing device (not shown) that senses the amount of collected waste. When the sensing device detects that the amount of collected waste in waste container 330A is almost full, a signal is sent to suspension unit 310 to raise waste container 330A.

[0033] 9-11. In some embodiments, the waste collection device 300 includes a container 350 and a fluid discharge element 360. The container 350 is installed adjacent to the floating units 210. For example, the container 350 is installed between the floating units 210. The fluid discharge element 360 is coupled to the base 211, the pillars 212, or the frame 220. The waste bag 320 and the container 350 are referred to as a waste collection element, which has a space for collecting and storing waste.

[0034] The container 350 is used to collect and contain waste, thereby improving collection efficiency. In some embodiments, the interior of the container 350 is partitioned into several sections to separate the waste. For example, plastic, metal, and glass are separated from each other due to differences in their densities. In some embodiments, to facilitate the flow of water into the container 350, the container 350 is inclined relative to the flotation device 200, with the water level slightly above the lower front edge of the container 350. In some embodiments, the degree of inclination of the container 350 is adjusted according to the water level.

[0035] In some embodiments, the fluid ejection element 360 is a pipe. The fluid flowing out of the fluid ejection element 360 flows along a predetermined path to a space (e.g., the space within the container 350) that collects waste. According to Bernoulli's principle, the fluid flowing out of the fluid ejection element 360 can reduce the pressure of the surrounding water, causing the surrounding water near the predetermined path to flow into the waste collection apparatus 100 along the predetermined path. This increases the amount of water flowing into the waste collection apparatus 100, thereby increasing the amount of waste flowing into the waste collection apparatus 100. In some embodiments, the fluid ejection element 360 is a curved pipe having a first section 361 and a second section 362 connected to the first section 361. In some embodiments, the first cross-section of the first section 361 is different from the second cross-section of the second section 362. For example, the first cross-section of the first section 361 is larger than the second cross-section of the second section 362, further increasing the flow rate of water exiting the fluid ejection element 360 and thereby increasing the amount of water flowing into the waste collection apparatus 100. In some embodiments, the angle 360A between the first section 361 and the second section 362 ranges from, but is not limited to, 70 degrees to 110 degrees.

[0036] In some embodiments, the angle of the fluid ejection element 360 and the velocity of the stream exiting the fluid ejection element 360 are adjusted to improve collection efficiency. In embodiments in which a sensing device is provided to sense the amount of collected waste, if the sensing device detects a large amount of waste approaching the waste collection device 100, a signal is sent to the fluid ejection element 360 to increase the flow rate of the stream exiting the fluid ejection element 360. If the sensing device detects only a small amount of waste approaching the waste collection device 100, a signal is sent to the fluid ejection element 360 to decrease the flow rate of the stream exiting the fluid ejection element 360 or close the fluid ejection element 360 to conserve energy.

[0037] The number of containers 350 and the number of fluid discharge elements 360 vary. As shown in FIGS. 9-11 , one or more containers 350 and one or more fluid discharge elements 360 are provided adjacent to the flotation unit 210, such as on the opposite side of the flotation unit 210 and below the flotation unit 210. For example, one or more containers 350 are installed on one side of the pillar 212 or below the base 211. Containers 350 located at different positions are used to collect waste at different depths, and different types of waste are collected at different depths. For example, containers 350 installed on one side of the pillar 212 are used to collect waste near the water level, such as containers. Containers 350 located below the base 211 are used to collect waste below the water level, such as fishing nets. The waste collection device 100 includes a suction pump (not shown). The suction pump is installed on the frame 220, the base 211, or the pillar 212. The suction pump lifts external water through the suction pipe and supplies the external water to the fluid discharge element 360 through the supply pipe.

[0038] See FIG. 12. In some embodiments, the waste collection device 300 includes a conveyor belt 370. The conveyor belt 370 is located in a space where the waste is collected (e.g., between the flotation units 210) and transports the waste. In some embodiments, the conveyor belt 370 is coupled to a frame 220, which temporarily stores the collected waste. In some embodiments, a waste storage unit (not shown) is coupled to the conveyor belt 370 to temporarily store the collected waste.

[0039] 13 and 14. To prevent the waste collection device 100 from moving, in some embodiments, the waste collection device 100 includes an anchor 450. The anchor 450 is attached to the frame 220 or at least one of the flotation units 210.

[0040] See Figure 15. In some embodiments, a building 500 is constructed on a floating unit 210 and a frame 220. The frame 220 distributes the weight of the building 500. The building 500 may be a building, a recreation facility, a gym, etc. In embodiments where solar panels are provided, the generated energy is supplied to different devices or elements of the waste collection apparatus 100, for example to operate the fluid discharge elements 360 or the conveyor belt 370.

[0041] To stabilize the waste collection apparatus 100 by keeping the center of gravity of the waste collection apparatus 100 relatively low, the density of the base 211 is greater than the density of the building 500. For example, the building 500 is made of expanded polystyrene (EPS) or expanded polypropylene (EPP), and the pillars 212 and the base 211 are made of concrete. In some embodiments, the number of flotation units 210 is determined by the size and weight of the building 500. For example, if the building 500 is relatively large, the number of flotation units 210 will be greater.

[0042] In some embodiments, outside water is utilized, for example, to supply the waste collection apparatus 100. For example, the building 500 may have a toilet (not shown), and outside water may be used to flush the toilet. For example, the building 500 may have a cooling system (not shown), and the waste collection apparatus 100 may have a suction pump (not shown). The suction pump uses suction to lift the outside water and also supplies the outside water to a cooling system to lower the temperature of the building 500. In some embodiments, the suction pump that supplies outside water to the fluid ejection element 360 also simultaneously supplies outside water to the building 500 above the waste collection apparatus 100.

[0043] It should be noted that the features of the various embodiments described above can be optionally combined with each other. For example, the combination of the inlet unit 340 and the conveyor belt 370 effectively increases the amount of waste entering the waste collection apparatus 100.

[0044] 16 and 17 , another type of waste collection device 600 is provided. The waste collection device 600 includes a flotation device 700 and a waste collection device 800 coupled to the flotation device 700. The flotation device 700 includes a plurality of flotation units 710. Each flotation unit 710 includes a base 711 and a pillar 712 connected to the base 711. The flotation device 700 further includes a platform 720 connected to the pillar 712. In some embodiments, the waste collection device 800 exhibits a space formed between the flotation units 710. This space is used to collect and store waste. In some embodiments, the waste collection device 800 includes elements adjacent to the flotation units 710, which are specifically used to collect and store waste. In some embodiments, the pillars 712 and the base 711 are hollow, and a stabilizing element 7111 is installed inside the base 711. In some embodiments, the base 711, pillars 712, and platform 720 are formed of fiber reinforced plastic (FRP), and the stabilizing element 7111 is formed of concrete, so that the gravitational force of the waste collection device 600 is relatively low, making the waste collection device 600 stable.

[0045] Referring now to FIG. 18, the base 711 has balancing elements 715A, 715B, and / or 715C. The balancing elements 715A, 715B, and / or 715C allow the floating unit 710 to maintain balance in the water. The balancing element 715A protrudes from the base 711. The balancing element 715B is a fin that protrudes from a portion of the base 711. The balancing element 715C surrounds a portion of the periphery of the base 711. In some embodiments, the balancing elements 715A, 715B, and / or 715C are referred to as "bilge keels." The placement and number of the balancing elements 715A, 715B, and / or 715C can be adjusted as needed, for example, to attenuate the forces of the floating device 700.

[0046] 19, 20A, and 20B. In this embodiment, the waste collection device 800 includes a mounting unit 810 and a waste bag 820. The waste bag 820 is coupled to the mounting unit 810. When the amount of collected waste in the waste bag 820 is almost full, an operator lifts the waste bag 820 relative to the mounting unit 810 (such as by operating a boat with a crane), so that the waste bag 820 can be removed from the mounting unit 810. In addition, the waste collection device 800 further includes two guide elements 880. The distance between the guide elements 880 gradually decreases along the water flow path, thereby guiding the waste into the waste bag 820. In some embodiments, each guide element 880 is wall-shaped.

[0047] To further improve collection efficiency, the waste collection device 800 further includes one or more fluid discharge elements 860. The fluid discharge elements 860 are located on the bottom surface of the platform 720. The waste collection device 600 also includes a suction pump (not shown). The suction pump is located above the platform 720. The suction pump raises external water through a suction pipe and supplies the external water to the fluid discharge elements 860 through a supply pipe. In FIG. 20A , multiple sets of fluid discharge elements 860 are located along the water flow path. In FIG. 20B , there is only one set of fluid discharge elements 860, but the fluid discharge elements 860 are installed on rails 890, allowing the fluid discharge elements 860 to move smoothly. For example, if the sensing device detects a large amount of waste, a signal is sent to the fluid discharge element 860, and the fluid discharge element 860 moves to a location where a large amount of waste has accumulated.

[0048] Referring now to Figure 21, another type of waste collection apparatus 1000 is provided. The waste collection apparatus 1000 includes a floating platform 1100 and a plurality of branching units 1200 connected to the floating platform 1100. The waste collection apparatus 1000 further includes a container 1350 installed below the floating platform 1100. A building 1500 is constructed on the floating platform 1100. Each branching unit 1200 includes a bottom plate 1210 and columns 1220 connected to the bottom plate 1210. The branching units 1200 help further stabilize the waste collection apparatus 1000 and prevent the waste collection apparatus 1000 from capsizing. In the waste collection apparatus 1000, the water level is designed to be within a certain range of the height of the columns 1220. The density of the bottom plate 1210 is greater than that of the pillars 1220 so that the water level is within a certain range of the height of the pillars 1220, and the center of gravity of the waste recovery apparatus 1000 is relatively low, making the waste recovery apparatus 1000 stable.

[0049] Referring now to FIG. 22, another type of waste collection device 1600 is provided. The waste collection device 1600 has two bases 1710 and multiple pillars 1720 connected to the bases 1710. The entire base 1710 and portions of the pillars 1720 are below the water level. The space between the bases 1710 is used to collect and contain waste. In some embodiments, the density of the bases 1710 is greater than the density of the pillars 1720. In some embodiments, the bases 1710 or the pillars 1720 have cavities inside. In some embodiments, the bases 1710 or the pillars have air-filled balls inside. The balls are made of plastic, but the material of the balls is not limited thereto.

[0050] Referring now to Figure 23, another type of waste collection device 2000 is provided. The waste collection device 2000 has a base 2100 and a plurality of pillars 2200. In this embodiment, the base 2100 is platform-like.

[0051] 24A and 24B, another type of waste collection apparatus 2600 is provided.

The floating apparatus 2700 includes a base structure 2710 and two hulls 2720 connected to the base structure 2710. The base structure 2710 is platform-like. In some embodiments, the structure and materials of the base structure 2710 are similar to those of the two hulls 2720. In some embodiments, the base structure 2710 and the two hulls 2720 have cavities or spaces inside. In some embodiments, the base structure 2710 and the two hulls 2720 include or are formed of steel, aluminum, concrete, reinforced concrete (RC), steel reinforced concrete, fiber reinforced plastic (FRP), or a combination thereof. The base structure 2710 and the two hulls 2720 may further comprise expanded polystyrene (EPS), expanded polypropylene (EPP), etc. embedded in steel, aluminum, concrete, reinforced concrete (RC), steel reinforced concrete, fiber reinforced plastic (FRP), etc. In some embodiments, the base structure 2710 and the two hulls 2720 are integrally formed during the same manufacturing process, thereby reducing costs.

[0052] In some embodiments, waste collection apparatus 2600 has a uniform density. In other words, the density of base structure 2710 is substantially the same as the density of two hulls 2720. In some embodiments, the density of base structure 2710 is lower than the density of two hulls 2720, sufficiently lowering the center of gravity of waste collection apparatus 2600. The composition and density of base structure 2710 and two hulls 2720 can be optionally adjusted according to actual needs (e.g., the center of gravity of waste collection apparatus 2600, or the distance between the bottom of base structure 2710 and the waterline).

[0053] In some embodiments, the continuous walls of the two hulls 2720 are tapered. In some embodiments, the waste collection apparatus 2600 can be used in relatively small bodies of water and / or in bodies of water that are not very choppy and have a specific flow direction, such as a river or stream. In some embodiments, the two hulls 2720 are attached to the riverbed or streambed. As water flows through the waste collection apparatus 2600, the two hulls 2720 reduce the resistance of the water. In some embodiments, the waste collection apparatus 2600 floats in the body of water, and an anchor (e.g., anchor 450) is attached to the waste collection apparatus 2600 to secure the waste collection apparatus 2600 in place.

[0054] In some embodiments, the waste collection device 2800 includes a handling unit 2810, a waste bag 2820, and two fluid discharge elements 2860, and the fluid discharge element 2860 outputs a fluid flow toward the waste bag 2820, where waste is collected. Note that the waste bag 2820 is placed in a waste container (e.g., waste container 330), and the waste container and / or the waste bag 2820 are moved by the handling unit 2810. The handling unit 2810 moves the waste container and / or the waste bag 2820 horizontally or vertically as needed. In some embodiments, the handling unit 2810 includes a lift fence, a motor, and a handling assembly connected to the motor's rotation shaft. Due to rotation of the motor (e.g., rotation), the handling assembly is driven by the lift fence to move the waste container and / or the waste bag 2820. In another embodiment, the waste containers and / or waste bags 2820 are moved from the handling unit 2810 by a boat having a lifting device.

[0055] 25A and 25B, another type of waste collection device 3000 is provided. The waste collection device 3000 includes a floating device 3100 and a waste collection device 3200 coupled to the floating device 3100. In this embodiment, the floating device 3100 is a catamaran (i.e., two boats coupled together). Thus, any catamaran that is not in operation can be used, thereby effectively utilizing the catamaran. The waste collection device 3200 represents the space formed between the catamarans. In some embodiments, the waste collection device 3200 further includes two fluid discharge elements 3360.

[0056] Next, referring to FIG. 26 , another type of waste recovery device 3600 is provided.

In this embodiment, there are four flotation units 3710, but the number of flotation units 3710 is not limited thereto. The flotation units 3710 are cylindrical. The waste collection device 3800 represents spaces formed between the flotation units 3710. In some embodiments, the waste collection device 3800 further includes two fluid discharge elements 3860. Compared to the embodiment shown in FIG. 6 , the space for collecting waste is larger in this embodiment.

[0057] 27A and 27B, another type of waste collection apparatus 4000 is provided. The waste collection apparatus 4000 includes a flotation apparatus 4100 and a waste collection apparatus 4200 coupled to the flotation apparatus 4100. The flotation apparatus 4100 includes a platform 4110, two posts 4120, and two bases 4130. The platform 4110 is connected to the base 4130 by the posts 4110. The waste collection apparatus 4200 represents a space formed between the platform 4110, the posts 4120, and the base 4130. In some embodiments, the waste collection apparatus 4200 further includes a handling unit 4310, a waste bag 4320, and two fluid discharge elements 4360. In this embodiment, the platform 4110 and the posts 4120 act as obstacles, increasing the likelihood that collected waste will accumulate in the waste collection apparatus 4000.

[0058] Referring now to FIG. 28, as shown in FIG. 28, according to some embodiments of the present invention, a wave glider 4400 is provided. The wave glider 4400 includes a waste collection device 3000 and an underwater device 4410. In some embodiments, the underwater device 4410 includes a plurality of fins 4411 and a connecting element 4412. The underwater device 4410 is coupled to and located below the waste collection device 3000. The underwater device 4410 is coupled to the floating device 3100 and / or the waste collection device 3200 by the connecting element 4412. The wave glider 4400 provides propulsion and / or converts wave energy to navigate through the water. As a result, as the amount of water flowing into the waste collection device 3000 increases, the amount of waste flowing into the waste collection device 3000 also increases. It should be noted that waste collection device 3000 is merely an example, and other waste collection devices, such as waste collection devices 100, 600, 1000, 1600, 2000, 2600, 3600, and 4000, are also included in Wave Glider 4400.

[0059] Referring now to Figures 29 and 30, waste collection apparatus is used as a floating platform on which wind turbine generator 4500 is mounted.

[0060] According to the present disclosure, a waste collection device for collecting waste from underwater is provided. The waste collection device includes a floating device including multiple floating units. Because each floating unit is manufactured using the same process, the stability of the waste collection device is ensured by the standardization of the manufacturing of the floating units. Furthermore, manufacturing costs are reduced due to standardization. Each floating unit includes a base and a pillar connected to the base. Because the density of the base is greater than the density of the pillar, the center of gravity of the waste collection device is relatively low, making the waste collection device stable. It should be noted that the floating device is any device that can float on water. That is, in some embodiments, the floating device does not have multiple floating units. Different devices or elements, such as waste containers, suspension units, receptacles, conveyor belts, etc., can be used to collect and contain waste. Furthermore, buildings can be constructed on the floating units, making the waste collection device versatile. In addition, the waste collection device can be used as a floating platform on which wind turbines are installed.
