[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 6 As shown, this utility model provides a suspended net cage for ecological flowing water fish farming, including a fixed frame 1, and multiple binding rings 18 are installed on the top surface of the fixed frame 1;

[0029] When this cage is deployed, the binding ring 18 is fixed by the traction rope, thereby limiting the deployment position of this suspended cage in the river channel;

[0030] A movable frame 2 is slidably mounted on the fixed frame 1, and four counterweights 17 are installed on the bottom surface of the movable frame 2;

[0031] Two symmetrically arranged spacing adjustment modules are installed between the fixed frame 1 and the movable frame 2;

[0032] Both spacing adjustment modules include a roller 15 rotatably connected to the fixed frame 1. The roller 15 is driven by a winding motor. Two traction belts 16 are wound on the roller 15. Both traction belts 16 are fixedly connected to the movable frame 2.

[0033] Before the net cage is set up, the relative distance between the fixed frame 1 and the movable frame 2 is controlled by setting the extension length of the traction belt 16 and cooperating with the counterweight 17. By adjusting the relative distance between the fixed frame 1 and the movable frame 2, the specifications and internal volume of the net cage are adjusted, thereby adjusting the fish storage capacity of the device.

[0034] A transmission module is installed on the fixed frame 1, and a first mesh belt 3 is connected to the transmission module. A driven module connected to the transmission module is installed on the movable frame 2, and a second mesh belt 4 is installed on the driven module.

[0035] The transmission module includes four active rollers 7 rotatably connected to the fixed frame 1. All four active rollers 7 are connected to the first mesh belt 3. A motor 8 is mounted on the fixed frame 1. The output shaft end of the motor 8 is fixedly connected to one of the active rollers 7.

[0036] The driven module includes four sets of driven rollers 9 rotatably connected to the inner wall of the movable frame 2. All four sets of driven rollers 9 are drivenly connected to the second mesh belt 4. Four square shafts 10 are rotatably mounted on the lower mesh plate 5. The interior of each of the four driving rollers 7 is provided with a square groove with an open bottom end. Each square groove is slidably connected to the square shaft 10. The cross-section of the square shaft 10 and the square groove is a regular polygon. A chain is drivenly connected to one of the driven rollers 9.

[0037] When the relative distance between the fixed frame 1 and the movable frame 2 changes, the square shaft 10 and the square groove enable the driving roller 7 to be continuously connected to the driven roller 9 and maintain transmission.

[0038] When the net cage is in use, the motor 8 periodically outputs a rotational speed. After the motor 8 outputs the rotational speed, the first net belt 3 and the second net belt 4 periodically rotate. After the first net belt 3 and the second net belt 4 periodically rotate, they repeatedly change their layout position in the river channel. This makes the first net belt 3 and the second net belt 4 evenly face the direction of water flow and water pollution, and the impact surface and circulation of the first net belt 3 and the second net belt 4 evenly face the direction of water flow and are cleaned by the outflow direction of water flow. This effectively reduces the scaling rate and clogging rate of the mesh holes of the first net belt 3 and the second net belt 4.

[0039] The bottom surface of the movable frame 2 is equipped with a lower mesh plate 5, and the inner wall of the fixed frame 1 is provided with an adjustable mesh plate 6.

[0040] A transmission screw 11 driven by a DC motor is rotatably mounted on the fixed frame 1. The transmission screw 11 is connected to the mesh plate 6. A guide rod 12 is mounted on the fixed frame 1. The guide rod 12 is slidably connected to the mesh plate 6. The axes of the transmission screw 11 and the guide rod 12 are parallel to the axis of the drive roller 7.

[0041] By setting the transmission screw 11, the placement position of the mesh plate 6 in this net cage and the relative distance between the mesh plate 6 and the lower mesh plate 5 are controlled. By changing the position of the mesh plate 6, the activity range and breeding depth of the farmed fish in this net cage are changed, thus adapting to different breeding needs of farmed fish.

[0042] The mesh board 6 is equipped with an electronic control mechanism, and the fixed frame 1 is equipped with an air purification module for pumping air to the first mesh belt 3 and the second mesh belt 4.

[0043] The electronic control mechanism includes a sealed box 13 installed on the network board 6. Inside the sealed box 13 are a microcontroller 14, a remote data transmission module, a three-axis accelerometer and a GPS locator. The data terminals of the three-axis accelerometer and the GPS locator are connected to the microcontroller 14.

[0044] By setting up a three-axis accelerometer, the swaying amplitude of the cage and the ripple of the river can be monitored in real time. By adjusting the ripple of the river, the position of the net plate 6 can be precisely adjusted and the fish farming depth can be adjusted.

[0045] By setting up a GPS locator, the deployment location of this cage can be accurately determined;

[0046] By setting up the remote data transmission module, this network box can receive and send data from remote central control in real time.

[0047] The air purification module includes an air pump 19 mounted on a fixed frame 1, an air distribution pipe 20 mounted on the fixed frame 1, and an air distribution chamber opened in two active rollers 7. The port of the air pump 19 is connected to the air distribution pipe 20, and the air distribution chamber is rotatably connected to the air distribution pipe 20. Multiple sets of regularly distributed air purification holes 21 are opened on the two active rollers 7 and the two square shafts 10, and each air purification hole 21 is connected to the corresponding air distribution chamber.

[0048] When this device is working, the air pump 19 periodically outputs air. After the air pump 19 outputs air, it can replenish oxygen for the farmed fish on the one hand, and on the other hand, it can achieve back cleaning of the first net belt 3 and the second net belt 4 through airflow, and clean the blockages in the first net belt 3 and the second net belt 4 through air cleaning.

[0049] Working principle and usage process of this utility model:

[0050] During the deployment of this net cage, the binding ring 18 is fixed by the traction rope, thereby limiting the deployment position of this suspended net cage in the river channel. Before deployment, the relative distance between the fixed frame 1 and the movable frame 2 is controlled by setting the extension length of the traction belt 16 and cooperating with the counterweight 17. By adjusting the relative distance between the fixed frame 1 and the movable frame 2, the specifications and internal volume of this net cage are adjusted, thereby adjusting the fish storage capacity of this device. When this net cage is in use, the motor 8 periodically outputs a rotational speed. After the motor 8 outputs a rotational speed, the first net belt 3 and the second net belt 4 periodically rotate. After the first net belt 3 and the second net belt 4 periodically rotate, they then move towards... By altering the placement of the first mesh belt 3 and the second mesh belt 4 within the river channel, the first mesh belt 3 and the second mesh belt 4 are evenly aligned with the direction of water flow and pollution. This ensures that the impact surfaces and circulation of the first mesh belt 3 and the second mesh belt 4 are cleaned by the outflow direction of the water, thereby effectively reducing the scaling and clogging rates of the mesh holes of the first mesh belt 3 and the second mesh belt 4. Simultaneously, during operation, the air pump 19 periodically outputs air. After the air pump 19 outputs air, it can both supplement oxygen for the farmed fish and achieve back-cleaning of the first mesh belt 3 and the second mesh belt 4 through airflow, thereby cleaning the blockages inside the first mesh belt 3 and the second mesh belt 4 through air cleaning.
