[0029] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1: See also Figure 1-8The present invention provides a photovoltaic power generation, fishery and light complementary breeding and fishing system, comprising a peripheral unit 10 and a fishing unit 50, wherein the peripheral unit 10 comprises a frame-shaped partition net 11, and the left and right ends of the frame-shaped partition net 11 are respectively connected to the columns 2 on both sides through a longitudinal sliding structure, and a plurality of the frame-shaped partition nets 11 are surrounded by the columns 2 to form a breeding space 30, and a bottom partition net 40 is arranged at the bottom of the breeding space 30, and the lower side of each frame-shaped partition net 11 is connected to the bottom partition net 40, and the fishing unit 50 is located at the opening side of the breeding space 30, and the fishing unit 50 comprises a net box, and the upper side of the net box is open, and the net box is provided with a channel 53 on the side close to the breeding space 30, and an opening and closing door 55 is installed on the channel 53, and the bottom partition net 40 is connected to one side of the channel 53 of the net box; when fishing, the frame-shaped partition net 11 is raised by the lifting structure to drive the fish into the fishing unit 50.

[0031] The aquaculture space 30 is formed by the peripheral unit 10 and the fishing unit 50. Aquaculture is carried out in the aquaculture space 30. Not only is the structure simple, but fish can directly obtain phytoplankton in the mud, and fishing and harvesting are also convenient.

[0032] In this embodiment, see Figure 3 , 6 7. The lifting structure includes a buoyancy box 12, which is installed at the lower end of the frame-shaped partition net 11. A vent pipe 121 is installed on the buoyancy box 12, and an inlet and outlet hole 122 is set at the bottom of the buoyancy box 12. The vent pipe 121 controls the water in the buoyancy box 12 to enter or discharge, thereby controlling the peripheral unit 10 to sink or float. When the peripheral unit 10 needs to sink, the vent pipe 121 is opened or air is pumped, and water enters the buoyancy box 12 from the inlet and outlet hole 122, so that the peripheral unit 10 sinks and hits the bottom of the water; when the peripheral unit 10 needs to float, pressurized air is injected into the buoyancy box 12 through the vent pipe 121, so that the water in the buoyancy box 12 is discharged from the inlet and outlet hole 122, and then the vent pipe 121 is closed, so that water will not enter the buoyancy box 12, and the peripheral unit 10 will float. When the peripheral unit 10 floats, the bottom partition net 40 is lifted at the same time.

[0033] For further information, see Figure 1 Or 3, a main air pipe 60 is installed on the column 2, and the main air pipe 60 is connected to the ventilation pipe 121 through a hose 61. The main air pipe 60 is connected to an air compressor or an air extraction device to control the sinking or floating of the peripheral unit 10.

[0034] Further, see Figure 7 The bottom of the buoyancy box 12 is provided with an insertion portion 13. The insertion portion 13 is used to insert into the silt to prevent the fish from escaping from the breeding space 30 due to gaps at the bottom of the buoyancy box 12. Preferably, the insertion portion 13 is a structure with a pointed portion at the lower end.

[0035] See also Figure 4The longitudinal sliding structure is a longitudinal slide groove 3 arranged on the side of the column 2, and the frame-shaped partition net 11 extends into the longitudinal slide groove 3.

[0036] In this embodiment, the longitudinal slide groove 3 is formed by two guide blocks 4 welded to the side surfaces of the column 2 .

[0037] Of course, the longitudinal slide groove 3 can also be a groove arranged on the main body of the column 2 .

[0038] See also Figure 8 The net box includes a frame 51 and a closed net 52. The closed nets 52 are respectively installed on the three side surfaces and the bottom surface of the frame 51. The frame 51 is respectively provided with door slots 54 on both sides of the passage 53. The opening and closing doors 55 are inserted and installed from the upper side of the door slots 54.

[0039] In order to facilitate opening or closing the opening and closing door 55, see Figure 1 , 3 8. A pull rope 56 is connected to the opening and closing door 55, and a pulley 5 is installed on the column 2 through a connecting beam 6. The pull rope 56 passes over the pulley 5 and extends to the shore.

[0040] Further, see Figure 8 The four corners of the frame 51 are respectively provided with avoidance grooves 511. Figure 5 A plurality of guide support wheels 57 are installed in the avoidance groove 511 on one side corresponding to the column 2. The fishing unit 50 is guided to rise and fall by the guide support wheels 57, so that the fishing unit 50 always moves in close contact with the column 2 during the rise and fall, preventing the fish from escaping from the gap. In addition, since the bottom partition net 40 is connected to one side of the channel 53 of the net cage, the fish will not escape from the side of the channel 53 when the peripheral unit 10 floats.

[0041] In this embodiment, the bottom partition net 40 is made of a flexible nylon net.

[0042] Further, in order to facilitate lifting the fishing unit 50 out of the water, see Figure 1 , 3 A lifting device 70 is installed on the column 2 through the connecting beam 6, and a lifting ring 512 is installed on the net box. The hook of the lifting device 70 is connected to the lifting ring 512 through a sling. When harvesting, the lifting device 70 is started to lift the fishing unit 50 out of the water or lower the water level to facilitate harvesting.

[0043] In this embodiment, the lifting device 70 is an electric winch.

[0044] Embodiment 2: Based on Example 1, see Figure 2A partition unit 20 is also installed in the breeding space 30. The partition unit 20 is connected to the pillars 2 on both sides through a longitudinal sliding structure. The breeding space 30 is divided into multiple partition spaces by multiple partition units 20. The bottom of each partition space is independently installed with a bottom partition net 40, and the opening side of each partition space is installed with a fishing unit 50. The structure of the partition unit 20 is the same as that of the peripheral unit 10. The height of the partition unit 20 is lower than that of the peripheral unit 10 or the same as that of the peripheral unit 10. When fishing, the partition unit 20 is lifted by the lifting structure. Through the above structure, different fish can be cultured and harvested in different areas.

[0045] Embodiment 3: Based on Example 1 or Example 2, see Figure 3 , a method for using the photovoltaic power generation fishery-light complementary aquaculture and fishing system is adopted, and the method for using includes: When breeding fish, the peripheral unit 10 is sunk to the bottom of the water by the lifting structure, and the fishing unit 50 is also placed on the bottom of the water to form a closed breeding space 30, and then the fry is put into the breeding space 30; during the breeding stage, the fixed pull rope 56 is pulled to open the opening and closing door 55 of the fishing unit 50; When fishing, the peripheral unit 10 is controlled to rise sequentially from the end away from the fishing unit 50 to the end where the fishing unit 50 is located, see Figure 3 The partition unit 20 on the middle left side is in a floating state at this time, and the fish are gradually driven to the right into the fishing unit 50. Then, the pull rope 56 is loosened to close the opening and closing door 55, and the fish are concentrated in the fishing unit 50, making fishing convenient.
