DETAILED DESCRIPTION

[0021] The following description is only a preferred embodiment of the utility model, the protection scope is not limited to the embodiment only, and any technical scheme under the idea of the utility model should belong to the protection scope of the utility model. It should be pointed out that, for ordinary skilled persons in the technical field, some improvements and decorations without departing from the principle of the utility model should be regarded as the protection scope of the utility model.

[0022] As shown in the figure, a plant net cage for ecological restoration of mud flat, the surface of the net cage main body 1 is provided with mesh 2.

[0023] The bottom of the net cage body 1 is provided with a stabilizing structure, which comprises a positioning rod 3, a counterweight 4, a moving rod 5 and a moving ring 6. The counterweight 4 is located at the bottom of the net cage body 1, the moving rod 5 is located around the counterweight 4, the moving rod 5 extends out of the net cage body 1 through the mesh 2, the positioning rod 3 is connected with the bottom of the counterweight 4, and the moving ring 6 is connected with the positioning rod 3 below the net cage body 1. The surface of the positioning rod 3 is wound with a positioning rope 7. The other end of the positioning rope 7 can be connected with each other and then connected to the shore or a ship, so as to facilitate the positioning of the net cage body 1 as a whole and the breeding and recovery.

[0024] The bottom of the moving rod 5 is provided with a deceleration hook 13 which is bent inward, and the included angle between the deceleration hook 13 and the bottom of the moving rod 5 is 30°-55°. The inner side of the moving ring 6 is horizontally connected with a deceleration rod 14, the two sections of the deceleration rod 14 are fixedly connected with the moving ring 6, the two sections of the deceleration rod 14 are located outside the moving ring 6, and a driving rod 15 is fixedly connected in the vertical direction below the moving ring 6.

[0025] When the net cage body 1 is impacted by seawater, the counterweight 4 increases the overall weight to prevent it from being overturned. During the movement and rotation of the net cage body 1 under the impact of waves and strong winds, the moving rod 5, the deceleration rod 14 and the driving rod 15 increase the contact area with the mudflat during movement, and the resistance increases and decreases to reduce the movement range. The deceleration hook 13 and the moving ring 6 increase the contact area with the mudflat during rotation, thereby increasing the resistance. The net cage body 1 is prevented from being lost and overturned. The moving ring 6 and the moving rod 5 contact the stones on and in the beach during movement, thereby buffering.

[0026] The upper surface of the counterweight 4 is provided with a water storage structure, which comprises a water storage tank 8, a filter layer 9 and a root system groove 10. The water storage tank 8 is opened on the upper surface of the counterweight 4, the filter layer 9 is fixedly connected with the top of the water storage tank 8, the root system groove 10 is opened on the upper surface of the counterweight 4, and the bottom of the root system groove 10 is connected with the bottom of the water storage tank 8. The root system groove 10 is provided with a breeding block 11, and the surface of the breeding block 11 is vertically provided with a planting groove 12. The planting groove 12 is a through groove, and the bottom of the planting groove 12 is located in the root system groove 10. The seawater entering between the counterweight 4 and the breeding block 11 through the mesh 2 is filtered by the filter layer 9 and stored in the root system groove 10, thereby improving the survival rate of plants during the ebb tide.

[0027] Working principle: the net cage is connected to the shore or the ship through the positioning rope 7, which is convenient for breeding and recycling. The connection part of the positioning rope 7 is located on the surface of the beach, and the main body 1 of the net cage is partially buried in the beach, which is convenient for positioning the whole net cage. The main body 1 of the net cage is impacted by seawater, and the counterweight 4 increases the overall weight to prevent it from being overturned. During the movement and rotation of the main body 1 of the net cage under the impact of waves and strong winds, the moving rod 5, the speed reduction rod 14 and the driving rod 15 increase the contact area with the beach during movement, and the resistance is increased to reduce the movement range. The speed reduction hook 13 and the moving ring 6 increase the contact area with the beach during rotation, and the resistance is increased. Prevent the net cage main body 1 from losing and overturning.

[0028] In summary, through the moving rod 5 and the speed reduction hook 13, the moving ring 6 and the speed reduction rod 14, the speed and range of movement and rotation of the main body 1 of the net cage under the impact of waves are reduced; the main body 1 of the net cage is prevented from being overturned by the counterweight 4.
