Description

Technical Field

[0001] This utility model relates to the field of algae collection technology, specifically to an automatic underwater algae collection device. Background Technology

[0002] Traditional algae collection mainly relies on manual harvesting, which is labor-intensive. Some equipment uses physical means such as water pumps to collect algae. Although this method does not rely on manpower, it still relies solely on external force to collect algae. Since algae are usually dispersed in water, especially during algal blooms, they often exhibit a diffuse vertical distribution. Relying solely on pumping or mechanical methods covers a small area of ​​water, resulting in low collection efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an automatic underwater algae collection device with high collection efficiency.

[0004] An automatic underwater algae collection device includes an algae collection box suspended in water. The side wall of the collection box has an inlet for water to flow into the collection box, and the bottom wall of the collection box has a drain outlet. A pumping mechanism is provided at the drain outlet to pump water out of the collection box. An intercepting net is provided inside the drain outlet to intercept and retain algae in the collection box. The collection box is equipped with an induction light source to emit light that induces phototaxis in algae, thereby inducing algae from the outside to gather on the outer periphery of the collection box.

[0005] Furthermore, it includes a floating body that floats on the water surface, with an algae collection box installed below the floating body.

[0006] Furthermore, the collection box is equipped with a first compression block and a second compression block. The first compression block is close to the second compression block to squeeze the water and algae in the collection box.

[0007] Furthermore, the first compression block and the second compression block are magnetic blocks that attract each other.

[0008] Furthermore, a fixed wall is provided in the middle of the collection box to divide the interior of the collection box into two areas: an upper chamber and a lower chamber. The water inlet is specifically opened on the side wall of the lower chamber of the collection box. The first compression block is connected to the lower surface of the fixed wall, and the second compression block is fixed on the bottom wall of the lower chamber.

[0009] Furthermore, the inside of the collection box is divided into two areas: an upper cavity and a lower cavity. The induction light source is specifically located in the upper cavity, and the outer peripheral sidewall of the upper cavity is a polarizing light sheet layer. The water inlet is specifically located on the sidewall of the lower cavity of the collection box, and the water outlet is specifically located on the bottom wall of the lower cavity of the collection box.

[0010] Furthermore, an algae collection port is opened on the bottom wall of the lower cavity, and an algae collection bag covers the outside of the collection port.

[0011] Furthermore, a one-way valve is installed at the collection port.

[0012] This utility model relates to an automatic underwater algae collection device. At night, an induction light source emits light to induce algae to gather around the outer perimeter of the collection tank. A pumping mechanism then creates a water flow: external water flows into the collection tank through the inlet, flows downwards, and is pumped out through the outlet. The algae gathered around the outer perimeter of the collection tank are carried along with this water flow and collected inside the tank. The induction light source utilizes the phototaxis of algae, covering a large area of ​​water, and combined with the physical force provided by the pumping mechanism, algae collection is highly efficient. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of an automatic underwater algae collection device. Detailed Implementation

[0014] The present invention will be further described in detail below with reference to specific embodiments.

[0015] like Figure 1 The underwater algae collection device shown has a floating body 8 floating on the water surface 9, and an algae collection box 6 installed below the floating body 8 and suspended in the water.

[0016] A light-shielding fixed wall 23 in the middle of the collection box 6 divides the interior of the collection box 6 into two areas: an upper cavity and a lower cavity. An induction light source 1 is located in the upper cavity. The outer periphery of the upper cavity is a polarizing light sheet layer 10. At night, the induction light source 1 emits light that induces phototaxis in algae: blue light at 470 nm and red light at 620-650 nm. This light passes through the polarizing light sheet layer 10, inducing algae from the outside to gather on the outer periphery of the collection box 6. The polarizing light sheet layer 10 filters the polarized light emitted by the induction light source 1 at a specific angle, reducing the scattering intensity of the induction light source 1 and minimizing its impact on animal behavior.

[0017] The lower cavity of the collection tank 6 has two opposing water inlets 3 located below the polarizing filter layer 10. An algae collection port 4 is located on the bottom wall of the lower cavity, covered by an algae collection bag 41. Next to the collection port 4, a suction port 5 is located on the bottom wall of the lower cavity. An intercepting net 51 is installed inside the suction port 5, and a pumping mechanism 50 is installed at the suction port 5 to create the following water flow: external water flows into the lower cavity of the collection tank 6 through the water inlets 3, flows downwards, and is either pumped out of the collection tank 6 through the suction port 5 or flows out through the collection port 4. Algae accumulated on the outer periphery of the collection tank 6 flows into the lower cavity of the collection tank 6 along with the aforementioned water flow through the water inlets 3, flows downwards, and is partially blocked by the intercepting net 51 inside the suction port 5, while the remaining portion flows out through the collection port 4 into the algae collection bag 41. A one-way valve 40 is installed at the collection port 4 to prevent backflow of water or algae. The induction light source 1 utilizes the phototaxis of algae to induce algae growth, covering a large area of ​​water. Combined with the physical force provided by the pumping mechanism 50, it collects algae with high efficiency.

[0018] The fixed wall 23 serves as the top wall of the lower cavity, and a cable controller 20 is fixedly installed on its lower surface. A cable (not shown in the figure) is fixed to the cable controller 20. The beginning of the cable is wound and connected to the cable controller 20, and the end is connected to a first compression magnet 21. The first compression magnet 21 is fixed above the collection port 4 by the cable. A second compression magnet 22 is fixed on the bottom wall of the lower cavity. The cable controller 20 periodically releases the cable wound around it. The first compression magnet 21, no longer fixed above the collection port 4, is attracted and descends by the second compression magnet 22. Under magnetic force, the first compression magnet 21 approaches the second compression magnet 22, squeezing the water and algae in the collection tank 6. The one-way valve 40 opens under pressure. Some water, after being squeezed, flows out of the collection tank 6 through the suction port 5, while the other part flows out through the one-way valve 40. The first compression magnet 21 presses some algae onto the second compression magnet 22 and the intercepting net 51, forming algal sludge. The algal sludge and the remaining algae flow with the water through the one-way valve 40 into the algae collection bag 41. The algae collection bag 41 and the intercepting net 51 are made of a material with a 30μm mesh. Water flows out through the algae collection bag 41 and the intercepting net 51, while the algal sludge and algae are intercepted and retained in the algae collection bag 41 and the lower chamber. After compression is complete, the cable controller 20 pulls the cable to pull the first compression magnet 21 back to the highest position and fix it.

[0019] The upper cavity of the collection box 6 is equipped with an induction light source 1 controller (not shown in the figure) to control the induction light source 1. The induction light source 1 controller is connected to a sensor assembly 11. The sensor assembly 11 is specifically located on the top of the collection box 6 and includes a chlorophyll concentration sensor, a temperature sensor, and a light intensity sensor. If the measured data reaches a specific threshold, the induction light source 1 controller will shut down the induction light source 1 to reduce the impact on animal behavior.
