Description

Technical Field

[0001] This utility model relates to the field of water ecological environment management technology, and more specifically, it is an automatic water surface debris retrieval device. Background Technology

[0002] Surface debris removal is a core component of aquatic ecological environment management, its significance encompassing ecological protection, public safety, resource sustainability, and socio-economic benefits. Floating debris (such as plastic waste, algae, and animal carcasses) releases organic matter and toxic substances, leading to eutrophication, reduced dissolved oxygen, and disruption of the ecological balance. Timely removal can break the pollution chain and restore the water body's self-purification capacity.

[0003] In current aquatic ecological environment management, debris removal mainly relies on manual operation, such as using nets and other tools. This method is inefficient, labor-intensive, and difficult to achieve rapid cleaning of large areas of water. Although some mechanized debris removal devices are available on the market, these devices generally suffer from problems such as complex structure, high cost, and inconvenient operation. Furthermore, they cannot effectively filter out water from the debris, resulting in low removal efficiency.

[0004] Therefore, existing methods for removing waste have drawbacks such as low efficiency, complex structure, high cost, and inconvenient operation of mechanized removal devices. Utility Model Content

[0040] The forward retrieval assembly includes a servo motor. A sprocket is fixedly mounted on the power output shaft of the servo motor.

[0043] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] Referring to the attached drawings, an automatic surface debris removal device includes a hull 1, with lateral debris removal components 2 on both outer walls of the hull 1, a drive source 3 installed on the top of the hull 1, a propeller 4 fixedly mounted on the power output shaft of the drive source 3, a base 5 and a support rod 7 fixedly mounted on the bottom of the inner wall of the hull 1, a forward debris removal component 6 on the inner wall of the hull 1, a rotary motor 8 fixedly mounted on the top of the support rod 7, a connecting shaft 9 fixedly mounted on the power output shaft of the rotary motor 8, a guide plate 10 fixedly mounted on the outer wall of the connecting shaft 9, a connecting plate 11 installed on the bottom of the connecting shaft 9, and a filter plate 12 rotatably connected to the inner wall of the hull 1.

[0045] The specific structure and function of the lateral retrieval component 2: The lateral retrieval component 2 includes a fixing plate 201. A micro motor 202 is fixedly installed on the outer wall of the fixing plate 201. A rotating shaft 203 is fixedly mounted on the power output shaft of the micro motor 202. A rotating arc-shaped block 204 and a filter screen 205 are respectively sleeved on the outer wall of the rotating shaft 203. A rack 206 is fixedly installed on the bottom of the inner wall of the filter screen 205. The dirt retrieved by the lateral retrieval component 2 is temporarily stored in the filter screen 205.

[0046] The lateral salvage assembly 2 consists of two sets, symmetrically distributed on both sides of the hull 1. The outer wall of the rotating arc block 204 is fixedly installed on the outer wall of the hull 1. The top of the rack 206 is sharp. The micro motor 202 is electrically connected to the controller.

[0047] Using the above structure, after the micro motor 202 is started, it can drive the rotating shaft 203 to rotate on the inner wall of the rotating arc block 204, so that the filter screen 205 can move in an arc around the rotating shaft 203, realizing automatic retrieval of dirt in the water. Excess water will automatically leak out, effectively retrieval, and due to the setting of the rack 206, it can prevent dirt retrieved from the inner wall of the filter screen 205 from easily falling off.

[0048] The specific structure and function of the forward retrieval component 6: The forward retrieval component 6 includes a servo motor 601. A sprocket 602 is fixedly mounted on the power output shaft of the servo motor 601. One end of a chain 603 is meshed with the outer wall of the sprocket 602, and the other end of the chain 603 is meshed with a sprocket 604. A rotating roller 605 is fixedly mounted on the outer wall of the rotating roller 605. Retrieval blades 606 are connected to the outer wall of the rotating roller 605. A water filter hole 607 is provided at the bottom of the retrieval blades 606, and a baffle 608 is fixedly mounted on the top of the retrieval blades 606. Two rotating rollers 605 are connected by a limiting block 609. There are several retrieval blades 606, evenly distributed on the outer wall of the limiting block 609, and the retrieval blades 606 are interlocked. The bottom of the servo motor 601 is fixedly mounted on the top of the base 5, and the servo motor 601 is electrically connected to the controller. The debris retrieved by the forward retrieval component 6 will eventually fall onto the top of the filter plate 12.

[0049] Using the above structure, after the servo motor 601 is started, it can drive the first sprocket 602 to rotate, so that the chain 603 drives the rotating roller 605 to rotate synchronously through the second sprocket 604, so that the retrieval blade 606 can transport and clean up the dirt in the water, achieving the purpose of automatic retrieval.

[0050] Electrical connection and function of drive source 3 and rotating motor 8: Both drive source 3 and rotating motor 8 are electrically connected to the controller. There are two rotating motors 8, connecting shaft 9, guide plate 10, and connecting plate 11, symmetrically distributed on both sides of the hull 1. The outer wall of the connecting plate 11 away from the guide plate 10 is fixedly installed to the outer wall of the hull 1. The guide plate 10 is fixedly mounted on the outer wall of the connecting shaft 9, and its main function is to guide the direction of water flow and debris movement. The design of the guide plate 10 optimizes the water flow path, making it easier for debris to be collected and transported to the forward retrieval assembly 6. The design of the guide plate 10 helps improve retrieval efficiency, ensuring that debris can smoothly enter the retrieval blades 606 of the forward retrieval assembly 6. The guide plate 10 and the forward retrieval assembly 6 work together to complete the collection and transport of debris. The guide plate 10 optimizes the water flow direction, guiding the debris to the retrieval blades 606 of the forward retrieval assembly 6. Driven by the servo motor 601, the retrieval blades 606 transport the debris from the water to the top of the filter plate 12 via a chain drive system. Therefore, the guide plate 10 plays a guiding and assisting role at the front end of the forward retrieval assembly 6, ensuring that the debris can efficiently enter the forward retrieval assembly 6 for processing.

[0051] Using the above structure, the filter plate 12 can perform simple sorting of the dredged waste, making subsequent waste recycling more convenient and improving work efficiency.

[0052] Working principle:

[0053] When using this device, place it in the water, start the drive source 3, and the propeller 4 rotates, propelling the retrieval device forward. At this time, the servo motor 601 starts, driving the first sprocket 602 to rotate, causing the chain 603 to drive the rotating roller 605 synchronously via the second sprocket 604. The retrieval blades 606 transport and clean the debris in the water, achieving automatic retrieval. Simultaneously, the micro motor 202 starts, driving the rotating shaft 203 to rotate on the inner wall of the rotating arc block 204. The filter screen 205 moves in an arc around the rotating shaft 203, automatically retrievaling debris from the water. Excess water automatically leaks out, effectively retrieval, and the rack and pinion 206 prevents debris from easily falling off the inner wall of the filter screen 205. The retrieved debris falls to the top of the filter plate 12, where it performs simple sorting, facilitating subsequent recycling and improving work efficiency. Through this structure, the device can automatically complete the retrieval of debris from the water.

[0054] All other unspecified parts belong to the prior art.
