Description

Technical Field

[0001] This utility model relates to the field of water management technology, specifically to an automatic device for dredging cyanobacteria, aquatic plants, and floating debris in river and lake management. Background Technology

[0002] River and lake management is a complex and systematic project involving multiple aspects such as water resource protection, water pollution prevention and control, water ecological restoration, and water area and shoreline management. It is of great significance for improving the ecological environment, ensuring water security, and promoting sustainable development. Aquatic weed removal is an important part of river water environment management. In order to avoid the symbiosis of algae and weeds and the potential hazards to the river environment, it is necessary to remove them using removal devices.

[0003] Currently, automatic dredging devices lack pre-treatment mechanisms. Typically, these devices rely on conveyor belts for automatic dredging. However, when the device is in an area with firmly rooted vegetation, this method is ineffective and prone to entanglement, affecting the device's operational stability and shortening its lifespan. Therefore, this paper proposes an automatic dredging device for cyanobacteria and aquatic plant debris in river and lake management. This device incorporates a pre-treatment mechanism, utilizing flipping, agitation, and crushing to pre-treat areas with firmly rooted vegetation. This improves the dredging quality in specific areas, extends the device's lifespan, and enhances its overall effectiveness. Utility Model Content

A return spring is sleeved on the outer side of the guide rods located on the outer side of the sliding frame. A drive motor is bolted to the outer side of the rotating frame, and the drive motor is connected to the rotating roller through a drive shaft.

[0010] Specifically, a lead screw is installed in the fixed frame via bearings, and a corresponding ball slider is sleeved around the lead screw. The ball slider is connected to a push plate via bolts. One end of the fixed frame is connected to a servo motor via bolts, and the servo motor is connected to the lead screw via a drive shaft.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] To facilitate the use of turning, stirring, and crushing methods, areas with firmly rooted roots are pre-crushed to improve performance. Figure 1-3 As shown, the present invention provides an automatic dredging device for cyanobacteria, aquatic plants and floating debris in river and lake management, which includes a frame 1, a pretreatment component 3 and a crushing component 4. A conveyor belt 2 is installed inside the frame 1, the pretreatment component 3 is rotatably connected to the bottom of the frame 1, the crushing component 4 is installed on one side of the frame 1 at the bottom of the conveyor belt 2, and a recycling component 5 is installed at the bottom of the crushing component 4.

[0026] The pretreatment component 3 includes a rotating frame 301, and the rotating frame 301 is mounted on the bottom of the frame 1 via a bearing. A rotating roller 302 is rotatably connected inside the rotating frame 301 via a rotating shaft. Movable grooves 303 are equidistantly provided on the inner side of the rotating roller 302. A sliding frame 304 is slidably connected inside the movable grooves 303. A blade 305 is bolted inside the sliding frame 304.

[0027] In use, the frame 1, rotating frame 301, rotating roller 302, movable groove 303, sliding frame 304 and blade 305 can assist the pre-treatment mechanism. By turning, stirring and crushing, aquatic plants and blue-green algae can be pre-crushed in areas with relatively firm root systems to ensure the salvage quality of conveyor belt 2.

[0028] The blade is made of stainless steel (305).

[0029] To improve continuity of use, for example, such as Figure 1 , Figure 4 As shown, the present invention also includes the following: the recycling component 5 includes a fixed frame 501 and a float 503. A push plate 502 corresponding to the float 503 is slidably connected to one side of the fixed frame 501. A pull rope 504 is provided between the floats 503. A sealing plate 505 is connected to the top of the float 503 by a hinge.

[0030] In use, the auxiliary recovery mechanism can be added through the fixing frame 501, push plate 502, float box 503, pull rope 504 and sealing plate 505. The salvaged items can be assisted in being boxed and thrown back into the water for transportation, which can replace the traditional storage method and reduce the number and frequency of round trip transportation of salvaged items. The outer surface of the float box 503 is bonded with an elastic pad.

[0031] For example, such as Figure 2 , 3As shown, the present invention also includes guide rods 306 bolted to both sides of the movable groove 303, and the guide rods 306 penetrate the sliding frame 304 through the reserved holes. The periphery of the guide rods 306 is located on the outside of the sliding frame 304 and a return spring 307 is sleeved thereon. The outer side of the rotating frame 301 is bolted to a drive motor 308, and the drive motor 308 is connected to the rotating roller 302 through a drive shaft.

[0032] During use, the guide rod 306 and the return spring 307 facilitate the retraction and reset of the sliding frame 304 by the elastic force after the pretreatment component 3 is used, thereby improving the safety of use and reducing the residue of the salvaged material on the surface, making it convenient for operators to clean regularly. The drive motor 308 facilitates the rotation of the rotating roller 302 for pretreatment operations. The drive motor 308 includes a protective cover.

[0033] For example, such as Figure 4 As shown, this utility model also includes a lead screw 506 installed in the fixed frame 501 via bearings, a corresponding ball slider 507 sleeved around the lead screw 506, and the ball slider 507 connected to the push plate 502 via bolts. One end of the fixed frame 501 is connected to the servo motor 508 via bolts, and the servo motor 508 is connected to the lead screw 506 via a drive shaft. The surface of the float box 503 is provided with a drainage hole 509.

[0034] During use, the position of the push plate 502 can be adjusted by controlling the ball screw 506, ball slider 507, and servo motor 508. The drain hole 509 facilitates the drainage of moisture from the material. A corresponding sealing plug is provided in the drain hole 509. A filter screen is provided in the float box 503 at the top of the drain hole 509. The operator can perform regular maintenance by applying grease to the surface of the ball screw 506. The servo motor 508 includes a protective cover.

[0035] For example, such as Figure 5 As shown, the present invention also includes the following: the crushing assembly 4 includes a receiving box 401, and the receiving box 401 is connected to the frame 1 by bolts. A guide groove 402 is provided inside the receiving box 401. A rotating rod 404 is installed in the guide groove 402 by bearings. A spiral blade 405 is bolted to the periphery of the rotating rod 404. A crushing roller 403 is connected to the top of the guide groove 402 inside the receiving box 401 by a rotating shaft. A crushing motor 408 is bolted to one side inside the receiving box 401, and the crushing motor 408 is connected to the crushing roller 403 by a drive shaft.

[0036] In use, the material receiving box 401, the guide chute 402, the rotating rod 404, the crushing roller 403 and the crushing motor 408 can crush and guide the salvaged material for recycling, improving the convenience of salvage and recycling.

[0037] For example, such as Figure 5 , 6 As shown, this utility model also includes a drive gear 406 fixedly sleeved at one end of the crushing roller 403, a driven gear 407 fixedly sleeved on the periphery of one end of the rotating rod 404, and the drive gear 406 meshing with the driven gear 407; a discharge port 409 is opened at the bottom of the receiving box 401, and the discharge port 409 communicates with the guide groove 402; a guide hopper 410 is bolted to the top of the receiving box 401, and the discharge end of the guide hopper 410 is located at the top of the crushing roller 403; a support frame 101 is bolted to the bottom of the frame 1, and the rotating frame 301 is rotatably connected to the support frame 101 through a rotating shaft.

[0038] In use, the driving gear 406 and driven gear 407 can be meshed to drive the crushing roller 403 and rotating rod 404 to work synchronously. The crushed material is easily fed into the floating box 503 for recycling through the discharge port 409. The rotating frame 301 is easily installed and rotated through the support frame 101. The rotary motor is connected to the support frame 101 by bolts. The rotary motor is connected to the rotating frame 301 through the drive shaft. The bottom of the frame 1 is equipped with a controller. The drive motor 308, crushing motor 408, rotary motor and servo motor 508 are all electrically connected to the controller through wires.

[0039] In use, the operator first fixes the frame 1 to one end of the salvage boat with bolts, so that the conveyor belt 2 can be immersed in the water. By manually turning on the conveyor belt 2, seaweed, aquatic plants and scum in the water can be transported upward for automatic salvage. When the salvage boat reaches an area with relatively firm roots, the rotary motor can be manually turned on in advance to drive the rotating frame 301 to rotate to the outside of the conveyor belt 2. The drive motor 308 drives the rotating roller 302 to rotate, and the generated centrifugal force pushes the sliding frame 304 in the movable groove 303 outward. The exposed blades 305 can pre-crush the material. Then, the pre-crushed material can be transported upward by the conveyor belt 2 for salvage and recycling. The pre-treatment component 3 is set to ensure the quality of automatic salvage of the conveyor belt 2 in areas with firm roots, and at the same time, it can greatly reduce the occurrence of entanglement, thereby improving the stability of the device and greatly reducing the frequency and number of manual maintenance.

[0040] Furthermore, under the conveyor belt 2, the salvaged material can automatically fall into the receiving box 401 through the guide hopper 410. Driven by the crushing motor 408, the crushing roller 403 can crush the material. The crushed material falls into the guide trough 402. Simultaneously, the drive gear 406 meshes with the driven gear 407, driving the rotating rod 404 and the spiral blade 405 to rotate, forming a spiral feeding structure. The crushed material is then fed from the discharge port 409 into the bottom float box 503. Water in the material can be drained through the drain hole 509. The servo motor 508 drives the lead screw 506 to rotate, and the ball block slider 507 can drive the push plate 502 to slide slowly, so that the float 503 can be pushed by the push plate 502 to carry out material receiving and recovery operations in sequence. After the sealing plate 505 is closed, the operator can throw the float 503 filled with salvaged materials into the water, and then tie one end of the pull rope 504 to the side of the boat for transportation. This can greatly increase the storage capacity of the device, reduce the frequency of transporting salvaged materials back and forth, avoid interrupting the salvage operation, improve the continuity of the device's use, and make the use more reasonable and reliable.
