Description

Technical Field

[0001] The present invention relates to the technical field of underwater interception technology, and in particular to a retrieval and transfer device for an underwater interception net. Background Art

[0002] In the fields of water conservancy projects, marine resource development, aquaculture and environmental protection, underwater interception nets are widely used to intercept debris, fish or other objects in the water flow to achieve functions such as water purification, fishery resource protection and isolation of specific areas. However, the existing deployment, recovery and transportation methods of underwater interception nets have many shortcomings and need to be improved.

[0003] For example: 1. The deployment and recovery of traditional underwater interception nets mainly rely on manual operation. Operators need to manually deploy or recover the interception net on the water surface or underwater. This method is not only labor-intensive but also inefficient. Especially in large waters or complex underwater environments, the difficulty and risk of manual operation are significantly increased.

[0004] 2. Existing interception nets usually adopt a simple mesh structure and lack effective support and fixing devices. Under the action of water flow, the interception net is easily deformed, damaged, or even washed away by the water flow, resulting in poor interception effect. In addition, a single interception net structure is difficult to adapt to scenarios with different water flow speeds and interception requirements.

[0005] 3. The transportation of the interception net is an important part of the whole operation process. However, the existing technology lacks a special transportation device, and usually requires the use of a crane or other general equipment for transportation. This method is not only complicated to operate, but also easy to damage the interception net, while increasing the operation cost.

[0006] 4. During the deployment and recovery of the interception net, operators need to work on or near the water, especially in bad weather or complex water conditions, which poses a high safety risk. In addition, the existing devices lack necessary protective measures, which can easily lead to accidental injuries to operators.

[0007] 5. The interception net will intercept a lot of debris during use, and these debris need to be cleaned up regularly. However, there is a lack of effective collection devices in the prior art.

[0008] Therefore, it is necessary to design a retrieval and transfer device for an underwater interception net to solve the above problems. Summary of the invention

[0014] The interception net is in the shape of a trapezoid with a large opening and a small interior.
