A rapid treatment device for algal residue accumulation layers near lake shore

Abstract

This invention provides a rapid treatment device for algae debris accumulation layers near lake shores. It includes a near-shore algae debris collection and floating end, a lake-based treatment control end, and connecting rods. Heavier components such as a motor, water pump, battery, controller, and an algae-water separation zone for algae debris collection are all located at the lake-based treatment control end, which is positioned a certain distance from the lake shore in a deeper area, allowing for a greater draft. The near-shore algae debris collection and floating end does not feature heavy structures; instead, it incorporates a float plate, allowing it to float at a fixed water level. This enables floating algae debris to enter the cavity formed between the upper surface of the sand-control plate and the lower surface of the top plate, where it is then absorbed by the suction head. The combined operation of the near-shore algae debris collection and floating end and the lake-based treatment control end perfectly solves the problem of traditional algae harvesting boats being too heavy to approach the lake shore.

Description

Technical Field

[0001] This invention relates to the technical field of water body cleaning, and in particular to a rapid treatment device for algal residue accumulation layers near lake shores. Background Technology

[0002] The growth and reproduction of a suitable amount of green algae in large lakes can be beneficial to the lakes. Green algae have chloroplasts, which can increase the oxygen content in the water through photosynthesis, helping aquatic plants and animals to grow better. However, after the algae die, they lose their self-regulation ability and will accumulate in large quantities on the water surface. Under the action of wind and waves, they will accumulate along the lake shore, emitting an unpleasant odor. The algal toxins they release can also endanger aquatic animals.

[0003] Therefore, even in lakes with relatively good ecological environments, algae residue will accumulate along the shoreline. Because the water is shallow near the shore, it's difficult for ordinary algae-collecting boats to approach. Furthermore, the soil along the shoreline is soft due to water infiltration, and most lakes lack roads along their banks, making it inconvenient to use vehicles carrying water pumps to remove algae residue. Therefore, the usual method is to manually walk along the lakeshore and use filter nets to collect the algae residue. This method is labor-intensive and inefficient.

[0004] Therefore, there is an urgent need to design a device that can automatically clean up algae residue along the riverbank. Summary of the Invention

[0005] In response to the problems mentioned in the background art, this invention proposes a rapid treatment device for algal residue accumulation layers near lake shores.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0007] A rapid treatment device for algal debris accumulation layers near the lake shore includes a floating end for collecting algal debris near the lake shore, a treatment control end in the lake, and a connecting rod.

[0008] The near-shore algae residue collection end includes a sand-prevention board, a floating board, a top plate, a water depth sensor, a shore contact sensor, and a water intake end. The sand-prevention board is bowl-shaped with its opening facing upwards. The top plate covers the upper surface of the sand-prevention board, creating a cavity between the upper surface of the sand-prevention board and the lower surface of the top plate. A water inlet is provided on the sand-prevention board, allowing the cavity to connect with the water outside the near-shore algae residue collection end. The floating board is fixedly connected to the sand-prevention board, and the water depth sensor is fixed to either the sand-prevention board or the floating board to sense the near-shore water depth. The distance between the bottom of the algae residue collection end and the lake bottom is measured. A shore contact sensor is installed on the side of the sand-proof board or floating board facing the lake shore to sense whether the algae residue collection end is close to the lake shore. The water intake end is fixedly installed in the cavity, and the height of the water intake end is lower than the water inlet. By adjusting the size of the floating board, the algae residue collection end can float on the lake surface, while the water inlet is partially below the water surface and partially above the water surface. A water-permeable opening is provided on the bottom side of the sand-proof board away from the lake shore.

[0009] The lake treatment control unit includes a floating platform, left-right drive units, forward-backward drive units, a drive controller, an electric cylinder, a water pump, and an algae-water separation zone. The floating platform floats on the water surface and has an installation space inside. The left-right drive units include left-right drive motors and left-right drive blades. The drive shafts of the left-right drive motors are connected to the left-right drive blades. The left-right drive motors are located in the installation space, while the left-right drive blades are located outside the floating platform. The left-right drive motors can drive the left-right drive blades to rotate, causing the floating platform to move left or right. The forward-backward drive units include forward-backward drive motors and forward-backward drive blades. The drive shafts of the forward-backward drive motors are connected to the forward-backward drive blades. The forward-backward drive motors are located in the installation space, while the forward-backward drive blades are located outside the floating platform. The forward-backward drive motors can drive the forward-backward drive blades. The rotating mechanism moves the floating platform forward or backward. The electric cylinder is fixed in the installation space, with its shaft extending out and hinged to one end of a connecting rod. The connecting rod and the electric cylinder shaft rotate vertically and are fixed horizontally. The water pump is fixed in the installation space, with its inlet connected to the suction end via a flexible suction pipe. The outlet of the water pump is connected to the algae-water separation zone, which is a cavity located outside the floating platform. One side of the algae-water separation zone is composed of a filter screen with a mesh diameter smaller than that of algae residue. The algae-water separation zone is above the water surface. When the water pump pumps water and algae residue into the algae-water separation zone, the water flows out of the algae-water separation zone from the filter screen, while the algae residue remains in the algae-water separation zone. The drive controller receives information from the water depth sensor and the shore contact sensor and controls the operation of the left-right drive device, the forward-backward drive device, the electric cylinder, and the water pump.

[0010] The other end of the connecting rod is hinged to the sandproof plate, floating plate, or top plate. The connecting rod and the sandproof plate, floating plate, or top plate rotate vertically and are fixed horizontally.

[0011] To optimize the above technical solution, the specific measures also include:

[0012] The water depth sensor is mounted on a fixed float. The sensor includes a weight, a sliding rod, a chute, contacts, and a conductive actuator. The weight is an object with a density greater than water. The chute is located within the float and is open at its lower end. The upper half of the sliding rod is positioned within the chute and can slide up and down within it. The lower half of the sliding rod is located below the float, with its bottom end at the lowest point near the lake shore where algae debris is collected. The weight is fixed to the bottom of the sliding rod, and the conductive actuator is fixed to the upper half of the sliding rod. There are four pairs of contacts arranged vertically within the chute. The contacts are connected to the drive controller via wires. Each pair of contacts is initially open; when the conductive actuator contacts a contact, the pair is closed and sends an electrical signal to the drive controller.

[0013] The shore contact sensor is installed on the side of the float facing the lake shore. The shore contact sensor includes a mounting groove, a contact rod, a spring, and a pressure sensing plate. The mounting groove is located inside the side of the float facing the lake shore. The pressure sensing plate is vertically fixed in the mounting groove and is connected to the drive controller via wires. The contact rod is a T-shaped rod composed of a vertical component and a horizontal component. The vertical component is located in the mounting groove, and one end of the horizontal component is fixedly connected to the middle of the vertical component, while the other end extends out of the mounting groove. The other end of the horizontal component is the closest point to the lake shore where algae residue is collected. One end of the spring is fixedly connected to the mounting groove, and the other end is fixedly connected to the horizontal component. The spring provides a clearance fit between the vertical component and the pressure sensing plate. When the other end of the horizontal component is pressed against the lake shore, the contact rod moves towards the pressure sensing plate under external force, the spring deforms, and the vertical component presses against the pressure sensing plate, causing the pressure sensing plate to generate a pressure signal. The pressure sensing plate then transmits this signal to the drive controller.

[0014] The connecting rod is equipped with several latches. The wires between the water suction pipe, the pressure sensing plate and the drive controller, as well as the wires between the contacts and the drive controller, are all positioned on the connecting rod by the latches.

[0015] The sand-proof board and the top board are made of plastic boards, while the floating board is made of foam board.

[0016] The lake treatment control unit is equipped with a battery, which is connected to and powers the left and right drive motors, the front and rear drive motors, the drive controller, the electric cylinder, and the water pump.

[0017] The drive controller is a microcontroller.

[0018] The drive controller is connected to a wireless transceiver. The drive controller connects to a remote signal via the wireless transceiver, and the remote end can send control commands to the drive controller via the wireless transceiver.

[0019] A float sensor is installed at the top of the algae-water separation zone. The float sensor includes a float, a float rod, and a sensor. The float rod is slidably installed at the top of the algae-water separation zone. The sensor is fixed in the algae-water separation zone and located directly above the upper end of the float rod. The sensor is connected to the drive controller. The float is fixed at the lower end of the float rod. When the algae residue collected in the algae-water separation zone accumulates and exerts an upward thrust on the float, the float moves the float rod upward. The upper end of the float rod presses against the sensor, and the sensor transmits the sensed pressure signal to the drive controller.

[0020] Both the pressure sensing plate and the sensor are ceramic piezoelectric sheets.

[0021] The present invention has the following advantages:

[0022] This invention addresses the problem of traditional algae harvesting boats being difficult to approach due to shallow waters near the lake shore. It comprises two main parts: a near-shore algae debris collection floating end and a lake-based treatment and control end. Heavier components such as the motor, water pump, battery, controller, and algae-water separation zone for collection are located at the lake-based treatment and control end, which is positioned at a certain distance from the shore in deeper water, allowing for a greater draft. The near-shore algae debris collection floating end, however, is designed without heavy structures. Instead, it features a float plate that allows it to float at a fixed water level. This allows algae debris floating on the surface to enter the cavity between the upper surface of the sand-proof plate and the lower surface of the top plate, where it is absorbed by the suction head. The lightweight near-shore algae debris collection floating end allows it to float smoothly near the shore without touching the lake bottom, enabling it to operate effectively in shallow waters. The combination of the floating end for collecting algae debris near the lake shore and the control end for processing in the lake perfectly solves the problem that traditional algae harvesting boats are difficult to approach the lake shore due to their weight.

[0023] This invention designs a bowl-shaped sand-proof plate with the water intake end opening facing upwards. The sand-proof plate can prevent most of the lake bottom sediment from entering the cavity. The design of the water inlet part being below the water surface and part being above the water surface ensures that the water entering the cavity is water and algae residue from the water surface, which can effectively improve the collection efficiency.

[0024] This invention, through the design of a water depth sensor and a shore contact sensor, enables the controller to collect the position of the floating end of the algae residue collection device near the lake shore relative to the lake bottom and the lake shore. Then, through a forward and backward drive device, a drive controller, and an electric cylinder, the floating end of the algae residue collection device near the lake shore is controlled to perform position control. The invention has a high degree of automation and can save a lot of manpower.

[0025] The device of this invention can collect algae residues near the lake shore without human intervention. Staff only need to periodically process the algae residues in the algae-water separation zone. Attached Figure Description

[0039] like Figure 1As shown, the present invention provides a rapid treatment device for near-shore algal debris accumulation layers, which mainly consists of two parts: a near-shore algal debris collection floating end 1 and a lake-based treatment control end 2. The near-shore algal debris collection floating end 1 is located close to the lake shore, and the lake-based treatment control end 2 is located in the lake. The two are connected by a connecting rod 3, a water suction pipe 26a, and a wire.

[0040] like Figure 2-3 As shown, the near-shore algae residue collection end 1 includes a sand-proof board 11, a float 12, a top plate 13, a water depth sensor 4, a shore contact sensor 5, and a water intake end 14. The sand-proof board 11 is bowl-shaped with its opening facing upwards. The top plate 13 covers the upper surface of the sand-proof board 11, forming a cavity between the upper surface of the sand-proof board 11 and the lower surface of the top plate 13. A water inlet 15 is provided on the sand-proof board 11, allowing the cavity to communicate with the water outside the near-shore algae residue collection end 1. The float 12 is fixedly connected to the sand-proof board 11, and the water depth sensor 4 is fixed to the sand-proof board 11 or the float 12. 2. The bottom of the near-shore algae residue collection end 1 is used to sense the distance between the bottom of the near-shore algae residue collection end 1 and the lake bottom. The shore contact sensor 5 is installed on the side of the sand-proof board 11 or the floating board 12 facing the lake shore. It is used to sense whether the near-shore algae residue collection end 1 is close to the lake shore. The water intake end 14 is fixedly installed in the cavity. The height of the water intake end 14 is lower than that of the water inlet 15. By adjusting the size of the floating board 12, the near-shore algae residue collection end 1 can float on the lake surface. At the same time, the water inlet 15 is partially located below the water surface and partially located above the water surface. The bottom of the sand-proof board 11 is provided with a vertically penetrating water outlet 16 on the side away from the lake shore.

[0041] like Figure 4-5As shown, the lake treatment control unit 2 includes a floating platform 21, a left-right drive device 22, a forward-backward drive device 23, a drive controller 24, an electric cylinder 25, a water pump 26, and an algae-water separation zone 27. The floating platform 21 floats on the water surface and has an installation space inside. The left-right drive device 22 includes a left-right drive motor 22a and left-right drive blades 22b. The drive shaft of the left-right drive motor 22a is connected to the left-right drive blades 22b. The left-right drive motor 22a is located in the installation space, and the left-right drive blades 22b are located outside the floating platform 21. The left-right drive motor 22a can drive the left-right drive blades 22b to rotate, causing the floating platform 21 to move left or right. The forward-backward drive device 23 includes a forward-backward drive motor 23a and forward-backward drive blades 23b. The drive shaft of the forward-backward drive motor 23a is connected to the forward-backward drive blades 23b. The backward drive blade 23b is connected, the forward and backward drive motor 23a is located in the installation space, and the forward and backward drive blade 23b is located outside the floating platform 21. The forward and backward drive motor 23a can drive the forward and backward drive blade 23b to rotate, so that the floating platform 21 moves forward or backward. The electric cylinder 25 is fixed in the installation space. The electric cylinder shaft of the electric cylinder 25 extends out of the installation space and is hinged to one end of the connecting rod 3. The connecting rod 3 and the electric cylinder shaft are rotated in the up and down direction and fixed in the left and right direction. The water pump 26 is fixed in the installation space. The water inlet of the water pump 26 is connected to the water suction end 14 through the elastic water suction pipe 26a. The water outlet of the water pump 26 is connected to the algae-water separation zone 27. The algae-water separation zone 27 is a cavity located outside the floating platform 21. One side of the algae-water separation zone 27 is composed of a filter screen 28 with a mesh diameter smaller than that of algae residue. The algae-water separation zone 27 is higher than the water surface. The lake-based treatment control terminal 2 is equipped with a battery 29, which is connected to and powers the left-right drive motor 22a, the front-back drive motor 23a, the drive controller 24, the electric cylinder 25, and the water pump 26. A wireless transceiver is connected to the drive controller 24, which connects to a remote signal source, allowing the remote end to send control commands to the drive controller 24 via the wireless transceiver.

[0042] like Figure 6As shown, the water depth sensor 4 is mounted on the float 12. The water depth sensor 4 includes a drop body 41, a sliding rod 42, a groove 43, a contact 44, and a conductive actuator 45. The drop body 41 is an object with a density greater than water, and can be a stainless steel cone. The groove 43 is located in the float 12, with an opening at its lower end. The upper half of the sliding rod 42 is positioned within the groove 43 and can slide up and down within it. The lower half of the sliding rod 42 is located below the float 12. The bottom end of the slide rod 42 is the lowest point of the near-shore algae residue collection end 1. The weight 41 is fixed to the bottom end of the slide rod 42, and the conductive actuator 45 is fixed to the upper half of the slide rod 42. There are four pairs of contacts 44, which are arranged vertically in the slide groove 43. The contacts 44 are connected to the drive controller 24 by wires. Each pair of contacts 44 is in the open state. When the conductive actuator 45 contacts the contact 44, the pair of contacts 44 is connected and sends an electrical signal to the drive controller 24.

[0043] like Figure 7 As shown, the shore contact sensor 5 is installed on the side of the floating plate 12 facing the lake shore. The shore contact sensor 5 includes a mounting groove 51, a contact rod 52, a spring 53, and a pressure sensing plate 54. The mounting groove 51 is located inside the side of the floating plate 12 facing the lake shore. The pressure sensing plate 54 is vertically fixed in the mounting groove 51. The pressure sensing plate 54 is electrically connected to the drive controller 24 through a wire. The contact rod 52 is a T-shaped rod composed of a vertical part and a horizontal part. The vertical part is located in the mounting groove 51. One end of the horizontal part is fixedly connected to the middle of the vertical part, and the other end extends out of the mounting groove 51. The other end of the horizontal part is the closest point to the lake shore at the algae residue collection end 1. One end of the spring 53 is fixedly connected to the mounting groove 51, and the other end is fixedly connected to the horizontal part. The spring 53 makes the vertical part and the pressure sensing plate 54 fit together with a clearance.

[0044] like Figure 8 As shown, a float sensor 6 is installed at the top of the algae-water separation zone 27. The float sensor 6 includes a float 61, a float rod 62, and a sensor 63. The float rod 62 is slidably installed at the top of the algae-water separation zone 27. The sensor 63 is fixed in the algae-water separation zone 27 and located directly above the upper end of the float rod 62. The sensor 63 is signal-connected to the drive controller 24. The float 61 is fixed at the lower end of the float rod 62. When the algae residue collected in the algae-water separation zone 27 accumulates and exerts an upward thrust on the float 61, the float 61 drives the float rod 62 to move upward. The upper end of the float rod 62 squeezes the sensor 63, and the sensor 63 transmits the sensed pressure signal to the drive controller 24.

[0045] The method of using this invention is as follows: When algal remains accumulate along the lake shore, the algal remains float on the water surface. The near-shore algal remains collection floating end 1 and the lake treatment control end 2 are then connected... Figure 1-8After installation, the near-shore algae debris collection floating end 1 and the lake treatment control end 2 are placed in the lake water. The remote end sends information to control the drive controller 24, which activates the left-right drive device 22, moving the near-shore algae debris collection floating end 1 and the lake treatment control end 2 closer to the lake shore until the water depth sensor 4 or the shore contact sensor 5 is triggered. When the water depth sensor 4 is triggered, the water depth near the shore is already relatively shallow, and the sinker 41 is against the lake bottom. Under the action of the slope of the lake bottom, the sinker 41 will move upwards, causing the slide rod 42 to slide in the groove 43, and the contact point 44 connects... When the conductive actuator 45 is touched, an electrical signal is sent to the drive controller 24. The drive controller 24 operates according to the following logic based on the electrical signal from the conductive actuator 45: when the lowest contact 44 is closed, the left-right drive device 22 operates in the forward direction, pushing the near-shore algae debris collection float 1 further towards the shore; when the highest contact 44 is closed, indicating that the water depth below the near-shore algae debris collection float 1 is too shallow and there is a risk of stranding, the left-right drive device 22 operates in the forward direction, pulling the near-shore algae debris collection float 1 into the lake; when either of the two sets of contacts 44 in the middle is closed, the left-right drive device 22 stops operating. When the shore-touching sensor 5 is triggered, the contact rod 52 contacts the shore, pressing the pressure sensing plate 54. The pressure sensing plate 54 sends a pressure signal, and the drive controller 24 stops the left-right drive device 22. This ensures that the near-shore algae debris collection float 1 remains within a certain water depth area near the shore.

[0046] When the drive controller 24 stops the left and right drive device 22, the drive controller 24 starts the forward and backward drive device 23 and the water pump 26. Since the inlet 15 of the near-shore algae residue collection floating end 1 is partially below the water surface and partially above the water surface, water mixed with algae residue will enter the cavity between the upper surface of the sand-proof plate 11 and the lower surface of the top plate 13 to form a cavity. The water pump 26 uses the suction pipe 26a and the suction end 14 to suck both water and algae residue into the algae-water separation zone 27. During this process, if the water in the cavity is insufficient due to the large suction of the water pump 26 or other reasons, the near-shore algae residue collection floating end 1 will float up, thus preventing water from entering the inlet 15. This invention addresses this by setting a... There is a water inlet 16 that runs vertically through the cavity, allowing water to enter from below, thus ensuring a certain amount of water in the cavity and maintaining a continuous water intake at the inlet 15. The forward and backward drive device 23 drives the near-shore algae residue collection floating end 1 and the lake treatment control end 2 to move along the lake shore. During the movement, the shape of the lake shore and the water depth will also change. At this time, the drive controller 24 prioritizes using the electric cylinder 25 to control the left and right distance of the near-shore algae residue collection floating end 1. Specifically, when the lowest contact 44 is turned on, the electric cylinder 25 operates in the forward direction, pushing the near-shore algae residue collection floating end 1 towards the lake shore. When the highest contact 44 is turned on, the electric cylinder 25 operates in the reverse direction, pulling the near-shore algae residue collection floating end 1 towards the lake. When either of the two sets of contacts 44 in the middle is turned on, the operation of the electric cylinder 25 stops. When the shore contact sensor 5 is triggered, the contact rod 52 contacts the lake shore, pressing the pressure sensing plate 54. The pressure sensing plate 54 sends a pressure signal, and the electric cylinder 25 reverses its operation, pulling the near-shore algae residue collection floating end 1 a predetermined distance into the lake before stopping. This ensures that the near-shore algae residue collection floating end 1 remains within a certain water depth near the lake shore.

[0047] Water and algae residue collected in algae-water separation zone 27 are discharged back into the lake through filter screen 28, while algae residue is trapped by the filter screen and gradually accumulates in algae-water separation zone 27. When the algae residue accumulates to a certain height, it will contact the float 61, thus pushing the float 61 upward. The float sensor 6 then senses the height of the algae residue accumulation and sends a signal to the drive controller 24. The drive controller 24 sends the signal to the remote end via a wireless transceiver. The remote end issues a warning, and the staff sends a signal to the drive controller 24. The drive controller 24 activates the left-right drive device 22 and the forward-backward drive device 23 to adjust the position, so that the lake treatment control terminal 2 turns closer to the lake shore. The staff retrieves the lake treatment control terminal 2 and transfers the algae residue.

[0048] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
