A smart grid system for algae harvesting and treatment

Abstract

This utility model discloses an intelligent enclosure system for algae harvesting and treatment, relating to the field of algae treatment technology. The intelligent enclosure system includes a floating platform, with a harvesting mechanism above the platform for concentrating and harvesting algae. The harvesting mechanism includes: a recovery component, located above the floating platform, for recovering algae; and a limiting component, including connecting rods movably installed on both sides of the floating platform, with floats fixedly installed above the connecting rods, and silicone tubes inserted at both ends of the connecting rods. In the recovery component, the bottom of the conveyor belt is below the water surface, allowing direct contact with the algae and conveying them to a receiving frame.

Description

Technical Field

[0001] This utility model relates to the field of algae treatment technology, specifically to an intelligent grid system for algae harvesting and treatment. Background Technology

[0002] Traditional algae harvesting methods often result in target algae drifting and spreading due to water currents and waves, or mixing with other algae and impurities, increasing sorting costs. The intelligent enclosure system achieves "targeted capture" through a modular enclosure structure and environmentally adaptable design.

[0003] The existing utility model patent with publication number CN211735312U discloses a flexible intelligent algae-blocking enclosure, including several baffles connected movably to adjacent baffles; and an algae-blocking plate located on the baffles and curved away from the baffles. When the water surface undulates and generates waves, the waves are obstructed by the algae-blocking plate as they hit the baffles. They flow along the curved surface of the elastic flange, thus flowing away from the baffles. For example, if waves rise to the same height, without the elastic flange, the waves might overshoot the top of the baffle due to inertia; however, with the elastic flange, they will fall back into the enclosed area along the curved direction of the elastic flange, reducing the probability and speed of phytoplankton spread.

[0004] The aforementioned algae-blocking enclosure can only restrict the position of algae above the water surface, but cannot collect algae. Furthermore, the device uses a chain-like connection structure with interlocking rings, which may wear or even be damaged at the connection points under the influence of long-term water flow impact and relative movement between the baffles, affecting the connection strength of the baffles. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an intelligent enclosure system for algae harvesting and treatment, which solves the problems of water flow impact affecting the connection strength of the baffles and the inability to collect algae.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent enclosure system for algae harvesting and treatment includes a floating platform, and a harvesting mechanism for concentrating and harvesting algae is provided above the floating platform. The harvesting mechanism includes: A recovery assembly, located above the floating platform, is used to recover duckweed. The limiting assembly includes connecting rods movably mounted on both sides of the floating platform. A float bar is fixedly mounted above the connecting rod. Silicone tubes are inserted through both ends of the connecting rod. Pins are inserted inside the silicone tubes. A curtain is fixedly mounted below the connecting rod. A plumb bob is suspended below the curtain. A winding drum is provided on one side of the curtain. End caps are fixedly mounted at both ends of the winding drum. A winding shaft is movably mounted between the end caps. Torsion springs are fixedly mounted at both ends of the winding shaft.

[0007] Preferably, the recycling assembly includes a receiving frame disposed above the floating platform, a filter screen fixedly installed at the bottom of the receiving frame, a limiting frame fixedly installed at the rear bottom of the floating platform, a conveyor belt disposed between the limiting frame and the floating platform, a fixing frame fixedly installed above the limiting frame, a winding roller movably installed inside the fixing frame, a winding motor fixedly installed above the fixing frame, and a steel cable connected to the outside of the winding roller.

[0008] Preferably, the receiving frame is connected to the floating platform by bolts, the bottom of the inner cavity of the receiving frame has a conical structure, and the surface of the floating platform is provided with a notch that matches the opening structure at the bottom of the receiving frame.

[0009] Preferably, the inclined structure below the conveyor belt passes through the floating platform, and the bottom end of the conveyor belt is lower than the water surface. The upper and lower ends of the take-up roller are rotatably connected to the fixed frame and the limiting frame, respectively. There are two steel cables, one end of which is connected to the take-up roller and the other end of which is connected to the connecting rod.

[0010] Preferably, the connecting rods are connected by silicone tubes and pins, the adjacent connecting rods are mirror-symmetrical, the outer center of the silicone tube is provided with a disc-shaped protrusion structure, and the outer protrusion structure of the silicone tube is located between the hinge points of the adjacent connecting rods.

[0011] Preferably, the weights are installed at equal intervals below the curtain, one end of the curtain is connected to the floating platform, and the other end is wound around the outside of the winding shaft. The winding shaft is rotatably connected to the end caps on the upper and lower sides. The inner end of the torsion spring is fixedly connected to the winding shaft, and the outer end is fixedly connected to the end cap.

[0012] Beneficial effects This invention provides an intelligent enclosure system for algae harvesting and treatment. Compared with the prior art, it has the following advantages: (1) The intelligent grid system for algae harvesting and treatment abandons the traditional ring-type interlocking chain rigid connection structure for algae blocking and adopts a soft connection method consisting of connecting rods and floating platforms, and connecting rods connected by pins and silicone tubes. The disc-shaped protrusion on the outside of the silicone tube can reduce the direct friction and collision between adjacent parts when the connecting rods move relative to each other due to water flow impact. At the same time, the winding motor, winding roller and steel cable can flexibly adjust the angle of the connecting rods according to the water flow speed, avoiding wear and damage to the rigid connection due to long-term exposure to water flow impact at a fixed angle and relative movement of parts. Through the buffering effect of the soft connection and the dynamic adjustment of the angle, the impact resistance and durability of the connection structure are enhanced.

[0013] (2) The intelligent grid system for algae harvesting and treatment achieves complete harvesting through the coordinated operation of the limiting component and the recovery component. In the limiting component, the float ensures that the connecting rod floats on the water surface, and the lead weight causes the curtain to hang down to form a stable interception area. The two work together to confine the algae to a specific range and guide them to converge towards the front of the floating platform. In the recovery component, the bottom of the conveyor belt is lower than the water surface and can directly contact the algae on the water surface, transporting them to the receiving frame. The conical bottom of the receiving frame facilitates the accumulation of algae, and the filter screen and the gap of the floating platform can quickly separate the water in the algae, realizing the whole process operation from algae interception, convergence to collection and dehydration, solving the defect of traditional devices that can only limit the location of algae but cannot collect them.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: an intelligent grid system for algae harvesting and treatment includes a floating platform 1, and a harvesting mechanism 2 for concentrating and harvesting algae is arranged above the floating platform 1. The harvesting mechanism 2 includes: A recycling component 21, positioned above the floating platform 1, is used to recycle duckweed. The recycling component 21 includes a receiving frame 211 positioned above the floating platform 1. A filter screen 212 is fixedly installed at the bottom of the receiving frame 211. A limiting frame 213 is fixedly installed at the rear bottom of the floating platform 1. A conveyor belt 214 is provided between the limiting frame 213 and the floating platform 1. A fixing frame 215 is fixedly installed above the limiting frame 213. A winding roller 216 is movably installed inside the fixing frame 215. A winding motor 217 is fixedly installed above the fixing frame 215. A steel cable 218 is connected to the outside of 6. The receiving frame 211 is connected to the floating platform 1 by bolts. The bottom of the inner cavity of the receiving frame 211 is a conical structure. The surface of the floating platform 1 is provided with a notch that matches the bottom opening structure of the receiving frame 211. The bottom of the conveyor belt 214 is a sloping structure that runs through the floating platform 1, and the bottom end of the conveyor belt 214 is lower than the water surface. The upper and lower ends of the take-up roller 216 are rotatably connected to the fixed frame 215 and the limiting frame 213, respectively. There are two steel cables 218, one end of which is connected to the take-up roller 216, and the other end is connected to the connecting rod 221.

[0017] Specifically, the floating platform 1 can limit the position of the two side limiting components 22 and support the receiving frame 211. After the conveyor belt 214 is started, it can transport the algae on the water surface to the inside of the receiving frame 211. The water contained in the algae after entering the receiving frame 211 can be discharged through the bottom filter screen 212 and the opening structure of the floating platform 1. The winding motor 217 can adjust the rotation angle of the winding roller 216 to perform the operation of winding and unwinding the steel cable 218.

[0018] The limiting component 22 includes connecting rods 221 movably mounted on both sides of the floating platform 1. A float bar 222 is fixedly mounted above the connecting rods 221. Silicone tubes 223 are inserted through both ends of the connecting rods 221, and pins 224 are inserted inside the silicone tubes 223. A curtain 225 is fixedly mounted below the connecting rods 221, and a plumb bob 226 is suspended below the curtain 225. A winding drum 227 is provided on one side of the curtain 225, and end caps 228 are fixedly mounted at both ends of the winding drum 227. A winding shaft 229 is movably mounted between the end caps 228, and torsion springs 224 are fixedly mounted at both ends of the winding shaft 229. 210. Connecting rods 221 are connected by silicone tubes 223 and pins 224. Adjacent connecting rods 221 are mirror-symmetrical. A disc-shaped protrusion is provided at the center of the outer side of the silicone tube 223. The protrusion on the outer side of the silicone tube 223 is located between the hinges of adjacent connecting rods 221. Plumb bobs 226 are installed at equal intervals below the curtain 225. One end of the curtain 225 is connected to the floating platform 1, and the other end is wound around the outside of the winding shaft 229. The winding shaft 229 is rotatably connected to the end caps 228 on the upper and lower sides. The inner end of the torsion spring 2210 is fixedly connected to the winding shaft 229, and the outer end is fixedly connected to the end cap 228.

[0019] Specifically, the connecting rods 221 are connected to each other and to the floating platform 1 via pins 224 and silicone tubes 223, forming a flexible connection. This allows the silicone tubes 223 to reduce friction and impact force during water flow. The angle between the connecting rods 221 and the floating platform 1 is adjusted by retracting and extending the steel cable 218 to accommodate different water flow velocities. For faster flow, the steel cable 218 can be extended to increase the angle between the connecting rods 221 on both sides of the floating platform 1; for slower flow, the steel cable 218 can be retracted to decrease the angle. To adapt to different water flow velocities, the curtain 225 below the connecting rod 221 guides algae to converge towards the front of the floating platform 1 for collection. The winding drum 227 is fixed to both sides of the river channel through the outer frame structure. During the adjustment of the angle of the connecting rod 221, the internal torsion spring 2210 cooperates with the winding shaft 229 to ensure that the algae between the sides of the connecting rod 221 and the river channel are still blocked by the curtain 225 while the angle of the connecting rod 221 is adjusted. At the same time, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0020] During operation, the winding motor 217 above the fixed frame 215 drives the winding roller 216 inside the fixed frame 215 to rotate (the upper and lower ends of the winding roller 216 are rotatably connected to the fixed frame 215 and the limiting frame 213 at the bottom rear end of the floating platform 1, respectively), thereby realizing the winding and unwinding operation of the two steel cables 218. This adjusts the angle between the connecting rods 221 on both sides of the floating platform 1 and the floating platform 1—releasing the steel cables 218 to increase the angle when the water flow is fast, and winding the steel cables 218 to decrease the angle when the water flow is slow, to adapt to different water flow velocities. The floats 222 fixed above the connecting rods 221 ensure they float on the water surface. The connecting rods 221 are connected to the pins 224 via silicone tubes 223. The curtain 225 fixed below the connecting rods 221 is supported by equally spaced plumb bobs. Under the action of 226, the curtain 225 hangs down, and at the same time, the winding shaft 229, which is movably installed between the end caps 228 at both ends of the winding drum 227, cooperates with the torsion spring 2210 (the inner end is fixed to the winding shaft 229, and the outer end is fixed to the end cap 228) to ensure that the curtain 225 can still block the algae and guide them to converge towards the front of the floating platform 1 when the angle of the connecting rod 221 is adjusted. Subsequently, the conveyor belt 214 (the lower inclined structure penetrates the floating platform 1 and the bottom end is lower than the water surface) between the limiting frame 213 and the floating platform 1 is started, which transports the converged algae to the receiving frame 211 connected by bolts above the floating platform 1. The bottom of the inner cavity of the receiving frame 211 is a conical structure, and the filter screen 212 at its bottom end cooperates with the matching notch on the surface of the floating platform 1, so that the water in the algae is quickly discharged, and finally the concentrated harvesting of algae is completed.
