Description

Technical Field

[0001] The present invention relates to the technical field of aquatic fishing, and in particular to an underwater interception net. Background Art

[0002] Interception nets are used to intercept aquatic organisms and capture them.

[0003] Coastal nuclear power plants usually require seawater as cooling water for operation. In recent years, due to the seasonal growth of organisms such as shrimp, jellyfish, and enteromorpha, sudden blockages in the cold source outlets have occurred frequently, causing power generation units to shut down, posing a major safety hazard to the normal operation of industrial facilities such as coastal nuclear power plants. In order to prevent aquatic organisms such as shrimp from entering the cold source outlets, multiple interception nets are usually set up on the outer edge of the cold source outlets to catch them. The interception nets are fixed with piles and set perpendicular to the direction of the water flow. The water depth of the cold source outlet is more than 10 meters. The underwater installation process of the interception net is relatively complicated, requiring divers to dive for a long time to install it. When the sea current is strong and the wind and waves are strong, the safety hazard is greater.

[0004] Currently, there is an urgent need for an installation structure and an installation method that can realize the installation of an interception net on water. Summary of the Invention

[0005] In response to the problems existing in the prior art, the present invention provides an interception net installation structure that solves at least one of the above technical problems.

[0006] An underwater installation method for an interception net installation structure has solved at least one of the above technical problems.

[0007] The technical solution of the present invention is: an interception net installation structure, characterized by comprising a fixed gripper fixedly arranged on a fixed base, wherein the fixed gripper is provided with through holes for a traction rope and a fixed rope to pass through in parallel;

[0008] The traction mechanism further comprises a traction mechanism, the traction mechanism comprising a floating ball, a mounting guide wire and a ring connected in sequence from top to bottom, the ring passing through the traction rope and the fixing wire;

[0009] A pulling mechanism is installed between adjacent fixed grippers;

[0010] It also includes a hook, which is arranged on the mesh of the interception net and is used to hook the fixed mesh;

[0011] It also includes two left and right rope twisting machines, which are installed on the top of the fixed base and are used to pull, tighten and fix the ends of the fixed rope.

[0012] The present invention facilitates the installation and disassembly of the interception net by optimizing the installation structure of the interception net. One end of the fixed wire is released from the wire winch, and the other end of the fixed wire is pulled out from the fixed gripper, thereby achieving the release of the interception net. During installation, this can be achieved on the water. The traction rope carries the fixed wire through each fixed gripper, and at this time, the fixed wire also passes through the rings between the fixed grippers. The entire pulling mechanism is pulled through the float to pull the fixed wire out from underwater. After the fixed wires in different areas are relatively fixed to the hooks in different areas of the interception net, the interception net is put into the water and the fixed wire is pulled and tightened.

[0013] Further preferably, the fixed gripper is installed on the flow-facing side of the fixed base.

[0014] Further preferably, the spacing between adjacent fixed grips is the same, and the number of hooks between adjacent fixed grips is the same.

[0015] More preferably, it further comprises a guide wheel group, wherein the guide wheel group is mounted on the fixed base, and the guide path of the guide wheel group is a U-shaped structure;

[0016] The traction rope and the fixed rope are both located in the gap surrounded by the guide wheel group and the fixed base.

[0017] Further preferably, the fixed base includes a bottom base located at the bottom and two fixed piles arranged on the left and right, and the fixed grippers are fixed on both the fixed piles and the bottom base;

[0018] The connection line of the arrangement of the fixed grippers forms a U-shaped structure.

[0019] Further preferably, the fixing rope and the traction rope have different thicknesses.

[0020] Easy to distinguish.

[0021] A method for installing an interception net installation structure on water, characterized by comprising the following steps:

[0022] Step 1: The traction rope passes the fixed wire through the holes of the fixed grips one by one. At this time, the fixed wire also passes through the rings between adjacent fixed grips at the same time.

[0023] Step 2: Pull the pulling mechanism to pull the fixed line out of the water;

[0024] Step 3: Connect the hooks on the interception net to the fixed line and place the interception net underwater;

[0025] Step 4: The rope winder tightens the two ends of the fixed rope to complete the fixation of the intercepting net.

[0026] When the interception net needs to be replaced, one end of the fixed wire is loosened and released from the wire winder, and another wire winder winds and pulls the fixed wire, and pulls the fixed wire out of the fixed gripper to complete the release of the interception net.

[0027] When installing a new interception net, repeat steps 1 to 4.

[0028] Before step 1, a traction rope is passed through the fixed gripper, and both ends of the traction rope are exposed to the liquid surface.

[0029] Beneficial effects: The present invention realizes the completion of the interception net replacement operation above the water surface, simplifies the operation process, reduces the difficulty of underwater installation of the interception net, and improves the net replacement efficiency by more than 30%; the interception net is fixed at multiple points through fixed grippers, which reduces the gap between the fixed piles and the net, improves the fishing efficiency; and improves the safety performance of the net installation.
