The fixing block 3 and the locking block 32 cooperate to clamp and fix the sliding rod 12 in the middle of the mounting frame 11. Through the above structure, the setting of tightening the fastening nut 33 to press against the locking block 32 to fix the sliding rod 12 in the middle of the mounting frame 11 forms a sliding rod 12 fixing structure, which realizes the function of fixing the sliding rod 12 in the middle of the mounting frame 11, improves the stability of the sliding rod 12 when installed in the middle of the mounting frame 11, and improves the convenience of adjusting the position of the propeller flow meter 13.

[0028] like Figure 3As shown, the limiting component includes a limiting block 4; the limiting block 4 is fixedly connected to the top of the sliding rod 12; during operation, the limiting block 4 is set at the top of the sliding rod 12. When the sliding rod 12 slides in the middle of the mounting frame 11, the size of the limiting block 4 is larger than the through hole in the middle of the mounting frame 11. When the sliding rod 12 slides downward, the limiting block 4 limits the sliding rod 12; through the above structure, the limiting block 4 limits the end of the sliding rod 12, forming a sliding limiting structure for the sliding rod 12, reducing the possibility of the sliding rod 12 falling off the middle of the mounting frame 11.

[0030] like Figure 4 As shown, the anti-slip component includes a pair of pads 6; the pads 6 are fixedly connected to the inner sidewalls of the fixing block 3 and the locking block 32; during operation, when the fixing block 3 and the locking block 32 clamp the sliding rod 12, the pads 6 contact the outer sidewall of the sliding rod 12, increasing the friction when the fixing block 3 and the locking block 32 contact the sliding rod 12, reducing the slippage that occurs when the fixing block 3 and the locking block 32 clamp the sliding rod 12, and improving the stability of the sliding rod 12 when it is fixed.

[0031] During operation, the flow velocity detection component has a detection unit at one end and a photovoltaic power generation unit at the other. The detection unit is installed in a suitable position inside the net cage body 1 via a fixing component. The photovoltaic power generation unit is installed on the floating component, which is placed on the water surface. The photovoltaic power generation unit supplies power to the detection unit. The flow velocity detection component uses solar power to detect the water flow velocity inside the net cage body 1.

The signal processing module 15 and the photovoltaic power generation module 16 are installed on the floating component. The outer layer of the connecting cable 14 is made of tensile-resistant material, and the inner layer contains power supply and signal lines. Sunlight shines on the top of the photovoltaic power generation module 16, which generates electricity to power the signal processing module 15 and the propeller current meter 13. The propeller current meter 13 detects the water flow velocity inside the cage body 1, and the detection data is transmitted to the signal processing module 15 through the connecting cable 14. The signal processing module 15 processes the data and sends it to an external receiver. The floating board 2 is placed on the water surface, and the airbag 21 provides buoyancy to the floating board 2. The sinker 23 falls below the water surface, and the rope 22 is pulled by the weight of the sinker 23. Pull the float plate 2 straight down so that its top is exposed above the water surface, supporting the signal processing module 15 and the photovoltaic power generation module 16 on the water surface. When it is necessary to adjust the position of the propeller-type current meter 13 inside the net cage body 1, slide the sliding rod 12 to the appropriate position, tighten the fastening nut 33, and the fastening nut 33 moves on the outer wall of the wire rod 31 and presses against the locking block 32. The fixing block 3 and the locking block 32 cooperate to clamp and fix the sliding rod 12 in the middle of the mounting frame 11. The limiting block 4 is set at the top of the sliding rod 12. When the sliding rod 12 slides in the middle of the mounting frame 11, the size of the limiting block 4 is larger than the through hole in the middle of the mounting frame 11. When the sliding rod 12 slides downward, the limiting block 4 limits the sliding rod 12. When adjusting the position of the sliding rod 12, hold the handle 5, with your hand in contact with the sponge sleeve 51, and pull the handle 5. The handle 5 will drive the limiting block 4 and the sliding rod 12 to rise and fall, thereby adjusting the position of the sliding rod 12. When the fixing block 3 and the locking block 32 clamp the sliding rod 12, the pad 6 contacts the outer wall of the sliding rod 12, increasing the friction when the fixing block 3 and the locking block 32 contact the sliding rod 12, reducing the slippage that occurs when the fixing block 3 and the locking block 32 clamp the sliding rod 12, and improving the stability of the sliding rod 12 when it is fixed.
