In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Example one
As shown in fig. 1, 2 and 3, the present embodiment provides a fishing net rope connector, including:

In the specific implementation process, the base is a fishing ground net hanging structure which is a steel frame structure and floats on the water surface in the normal use state of the fishing net, and the base can be used for supporting the fishing net rope connector.
The working principle is as follows: the steel rope is connected to the bottom end of the tension rod 1, a downward tension (i.e. the tension of the steel rope) is formed on the tension rod 1, the tension (i.e. the tension of the steel rope) is transitionally applied to the support sleeve 2 through the connecting piece 6, after the support sleeve 2 receives the tension (i.e. the tension of the steel rope), the received tension (i.e. the tension of the steel rope) is transmitted to the pressure sensor 3, the pressure sensor 3 measures the tension (i.e. the tension of the steel rope) in real time or regularly, and when the tension of the steel rope detected by the pressure sensor 3 is smaller than a preset tension, the steel rope is in a loose state and needs to be tensioned.
When the pressure sensor 3 detects that the rope is in a loose state, the loose rope can be tensioned by adjusting the relative position of the tension rod 1 and the support sleeve 2, i.e. the relative position of the pin hole 11 and the insertion hole 21, and fixing the tension rod by the connecting piece 6.

the pressure sensor 3 is fixedly connected with the fixing mechanism 5 through the steel plate spring 4.
In the implementation process, the steel plate spring 4 is used for providing a part of pretension force after the steel rope is tensioned and ensuring a certain elastic deformation of the steel rope. When the tension that pressure sensor 3 will receive was given steel plate spring 4 for, steel plate spring 4 wholly received a decurrent power, and because steel plate spring 4's resilience, steel plate spring 4 has a trend and the resilience force of recovering deformation, and this resilience force provides partly pretension and guarantees that the wire rope has certain elastic deformation after the wire rope is taut.
Specifically, in the fishing net rope connector, the tension rod 1 is a movable part, the support sleeve 2, the pressure sensor 3 and the steel plate spring 4 are sequentially arranged from top to bottom and are immovable parts, the immovable parts are integrally connected with the two side edges of the steel plate spring 4 and the fishing ground net hanging structure.
As an alternative embodiment, the pressure sensor 3 is fixedly connected below the support sleeve 2.
As an optional embodiment, the tension rod 1 includes a connecting section 12 and a circular tube section 13, which are axially connected, the connecting section 12 is disposed at one end of the tension rod 1 close to the steel rope for hanging the steel rope, and the circular tube section 13 is externally sleeved with the supporting sleeve 2 and the pressure sensor 3.
As an alternative embodiment, the connecting section 12 is a sheet-like structure. In practical implementation, the connecting section 12 and the circular tube section 13 are smoothly transited through an arc section, and the sheet structure facilitates threading of a steel rope.
As an alternative embodiment, the plate-shaped section 12 is provided with a connecting hole 121, and the tension rod 1 is connected to the wire rope through the connecting hole 121.
As an alternative embodiment, the number of the insertion holes 21 is one.
