[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-4This utility model embodiment provides a protective device for rice-fish farming, comprising: a first guardrail 1 and a second guardrail 2. The side end of the first guardrail 1 is rotatably connected to the second guardrail 2. A third guardrail 3 is slidably connected to the outside of the second guardrail 2. The first guardrail 1, the second guardrail 2, and the third guardrail 3 form a closed structure. There are two of each of the first guardrail 1, the second guardrail 2, and the third guardrail 3, which are symmetrically arranged on both sides. The side end of the third guardrail 3 is rotatably connected to another first guardrail 1. An installation plate 4 is fixedly connected inside the first guardrail 1. An overlapping plate 5 is fixedly connected to the outside of the installation plate 4. A first motor 6 is fixedly connected inside the overlapping plate 5. A lead screw 7 is fixedly connected to the output end of the first motor 6. The end of the lead screw 7 away from the first motor 6 is rotatably connected to the installation plate 4. The inside of the installation plate 4 is a U-shaped structure. A positioning frame 8 is threadedly connected to the outside of the lead screw 7. The outside of the positioning frame 8 is slidably connected to the installation plate 4. The positioning frame 8 is an L-shaped structure.

[0022] Specifically, the closed mesh structure formed by the first guardrail 1, the second guardrail 2 and the third guardrail 3 can protect the fish fry in the pond and prevent them from escaping. Starting the first motor 6 drives the lead screw 7 to move the positioning frame 8 up and down. At the same time, starting the second motor 9 drives the bent connecting rod 10 to rotate, so that the slider 11 moves linearly along the guide rod 12.

[0023] A receiving plate 13 is fixedly connected to the lower surface of the positioning frame 8. A second motor 9 is fixedly connected inside the positioning frame 8. A bent connecting rod 10 is fixedly connected to the output end of the second motor 9. A slider 11 is fixedly connected to the outside of the bent connecting rod 10. A guide rod 12 is slidably connected inside the slider 11. A swing frame 14 is fixedly connected to both ends of the guide rod 12. Both ends of the swing frame 14 are rotatably connected to the receiving plate 13. A movable plate 15 is fixedly connected to the outside of the swing frame 14. The cross-section of the movable plate 15 is a T-shaped structure.

[0024] Specifically, starting the second motor 9 drives the bent connecting rod 10 to rotate, causing the slider 11 to move linearly along the guide rod 12. This causes the guide rod 12 to swing back and forth between the swing frame 14 and the movable plate 15 under the push of the slider 11, thereby driving away the birds.

[0025] A solar panel 16 is fixedly connected to the outside of the mounting plate 4, and a battery 17 is fixedly connected to the inside of the mounting plate 4. The battery 17 is electrically connected to the solar panel 16. A pull rope 18 is fixedly connected to the top of the first guardrail 1. A locking rod 19 is fixedly connected to the end of the pull rope 18 away from the first guardrail 1. Multiple reinforcing bars 20 are fixedly connected to the outside of the locking rod 19. The multiple reinforcing bars 20 are set along the inclined direction.

[0026] Specifically, solar panels 16 convert light energy into electrical energy and store it inside battery 17, which in turn provides power to motor 6. In addition, the pull rope 18, as a flexible connector, can effectively transfer the impact force borne by the first guardrail 1 to the locking bar 19, and form a triangular support structure with the inclined reinforcing strip 20, thereby significantly improving the ability to resist lateral loads.

[0027] Working principle: First, insert the locking rod 19 into the designated position. After the protective device is placed, bind the first guardrail 1 to the locking rod 19 with the pull rope 18, so that the position of the protective device can be fixed. Start the first motor 6 to drive the lead screw 7 to move the positioning frame 8 up and down. At the same time, start the second motor 9 to drive the bent connecting rod 10 to rotate, so that the slider 11 moves linearly along the guide rod 12. Thus, the guide rod 12 drives the swing frame 14 and the movable plate 15 to swing back and forth under the push of the slider 11, thereby driving away birds. When it is necessary to adjust the size of the protective device, first unbind the pull rope 18, and then push the third guardrail 3 to slide it outside the second guardrail 2, so that the range of the protective device can be flexibly adjusted. Then, fix the pull rope 18 again.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
