Description

Technical Field

[0001] This utility model relates to the field of underwater interception technology, and in particular to a device for deploying, taking down, and transferring an underwater interception net. Background Technology

[0002] Underwater interception nets are widely used in water conservancy projects, marine resource development, aquaculture, and environmental protection to intercept debris, fish, or other objects in water flows, thereby purifying water resources, protecting fishery resources, and isolating specific areas. However, existing methods for deploying, retrieving, and transporting underwater interception nets have many shortcomings and urgently need improvement.

[0003] For example: 1. Traditional underwater interception net deployment and retrieval mainly rely on manual operation. Operators need to manually deploy or retrieve the interception net on or underwater. This method is not only labor-intensive but also inefficient. Especially in large water areas or complex underwater environments, the difficulty and risk of manual operation increase significantly.

[0004] 2. Existing interception nets typically employ a simple mesh structure, lacking effective support and securing devices. Under the influence of water flow, these nets are prone to deformation, damage, or even being washed away, resulting in poor interception effectiveness. Furthermore, a single interception net structure is difficult to adapt to scenarios with varying water flow speeds and interception requirements.

[0005] 3. The transfer of the interception net is a crucial part of the entire operation. However, existing technologies lack specialized transfer devices, typically requiring the use of cranes or other general-purpose equipment. This method is not only complex to operate but also prone to damaging the interception net, while increasing operating costs.

[0006] 4. During the deployment and retrieval of the interception net, operators need to work on or near the water, especially in adverse weather or complex water conditions, posing a high safety risk. Furthermore, existing equipment lacks necessary protective measures, easily leading to accidental injury to operators.

[0007] 5. During use, the interception net will intercept a large amount of debris, which needs to be cleaned regularly. However, there is a lack of effective collection devices in the current technology.

[0008] Therefore, it is necessary to design a device for deploying, retrieval, and transferring underwater interception nets to solve the above problems. Utility Model Content

In addition, the lifting of the rollers at the bottom of the fixed seat is achieved through the screw sleeve connection and thread design, which makes the operation simple.
