[0007] Preferably, both sealing baffles extend through one side of the test chamber and are slidably connected to the test chamber. A connecting frame is fixedly connected between the two sealing baffles on one side, and a driving component for pulling the sealing baffles to move is provided on the outside of the connecting frame.
[0008] Preferably, the driving component includes a threaded rod that passes through the connecting frame and is threadedly connected to the connecting frame, and the threaded rod is rotatably connected to the test box.
[0009] Preferably, the traction component includes a dual-axis motor, which is fixedly connected to the bottom of the test device cabinet, and both output shafts of the dual-axis motor are fixedly connected to a first take-up reel.

[0013] This invention provides a device for testing the effects of magnetic fields on insects, which has the following beneficial effects:
[0014] 1. The test is conducted based on the principle that the magnetic field strength decreases exponentially with distance. The optimal magnetic field range is determined according to the migration of insects inside the test box. During the test, if the insects migrate to the lowest magnetic field range, the magnetic field can be further reduced, and if they move to the high magnetic field range, the magnetic field can be further increased.

[0024] This invention provides a device for testing the effects of magnetic fields on insects.
[0025] Please see Figures 1 to 6 An apparatus for testing the effects of magnetic fields on insects, comprising the following embodiments:
[0026] Please see Figures 1 to 5 Example 1: Includes a testing device cabinet 1, with a testing box 2 fixedly connected to the bottom of the testing device cabinet 1. The testing box 2 has two sealing baffles 4 inside. A magnetic field generator 3 for generating a magnetic field is located on one side of the testing device cabinet 1. A repelling baffle 8 is located inside the testing box 2 near the magnetic field generator 3, and the repelling baffle 8 is slidably connected to the inner wall of the testing box 2. A traction component is located on the side of the testing box 2 away from the magnetic field generator 3, used to pull the repelling baffle 8 to repel insects. A collection container 7 is threadedly connected to the side of the testing box 2 away from the magnetic field generator 3. A switching frame 701 is rotatably connected inside the collection container 7, and the switching frame 701 passes through the collection container 7. Three cover plates are hinged to the top of the testing box 2. The collection container 7 can be made of transparent material for easy observation.
[0027] In practical implementation, to test the effect of magnetic fields on insects, this device uses a magnetic field generator 3 installed on one side of the test chamber 2. The working principle of the magnetic field generator is mainly based on the principle of electromagnetic induction. A current of a certain frequency and intensity passes through the coil, thereby generating a corresponding magnetic field strength between the corresponding plates. The magnetic field generator is usually composed of a power supply module, a controller, and a coil. By adjusting and controlling the power supply module and the coil through the programmable controller, the required magnetic field parameters and waveforms can be obtained. By opening the top cover of the test chamber 2, a certain number of insects are placed inside the test chamber 2, and the sealing baffle 4 inside the test chamber 2 is removed. Then, the magnetic field generator 3 is activated to release the magnetic field. The test is conducted based on the principle that the magnetic field strength decreases exponentially with distance. The optimal magnetic field range is determined based on the migration of insects inside the test chamber 2. During the test, if the insects migrate to the lowest magnetic field range, the magnetic field can be further reduced; if they move to the high magnetic field range, the magnetic field can be further increased. The test chamber 2 can be made of transparent material for easy observation.
[0028] Please see Figure 3 In this embodiment, both sealing baffles 4 pass through one side of the test chamber 2 and are slidably connected to the test chamber 2. A connecting frame 5 is fixedly connected between the two sealing baffles 4 on one side, and a driving component for pulling the sealing baffles 4 is provided on the outside of the connecting frame 5.
[0029] The driving component includes a threaded rod 6, which passes through the connecting frame 5 and is threadedly connected to the connecting frame 5. The threaded rod 6 is rotatably connected to the test box 2.
[0030] In practice, by rotating the threaded rod 6, the threaded rod 6 is connected to the connecting frame 5 by threads, and the connecting frame 5 drives the two sealing baffles 4 to move, so that the insects can move inside the test box 2. The adjustment component can also be driven by a motor and a lead screw, which will not be elaborated further here.
[0031] Please see Figures 3 to 6 Example 2: The traction component includes a dual-axis motor 10, which is fixedly connected to the bottom of the test device cabinet 1. Both output shafts of the dual-axis motor 10 are fixedly connected to a first take-up reel 11. The dual-axis motor 10 can be a dual-axis motor with a self-locking function, and the specific model is not limited here.
[0032] The traction device also includes two traction ropes 9, which are respectively wrapped around the outside of the two first winding reels 11 and connected to the outside of the first winding reels 11. The traction ropes 9 pass through the test box 2 and are fixedly connected to the driving baffle 8.
[0033] In practical implementation, after the test is completed, the insects need to be removed. Therefore, this device has a repelling baffle 8 installed on one side inside the test chamber 2. By starting the dual-axis motor 10, the output shaft of the dual-axis motor 10 drives two first take-up reels 11 to rotate. The rotation of the first take-up reels 11 pulls the repelling baffle 8 to slide inside the test chamber 2 through the traction rope 9 fixed on the outside. In order to ensure that the repelling baffle 8 can slide stably inside the test chamber 2, a groove can be set at the bottom or top of the test chamber 2 to ensure that the repelling baffle 8 slides stably. The size of the groove is set so that the insects cannot pass through. When the repelling baffle 8 moves towards the dual-axis motor 10, the repelling baffle 8 continuously drives the insects to move. A collection can 7 is threaded on one side of the test chamber 2. The movement of the repelling baffle 8 drives the insects into the collection can 7. When the collection can 7 is removed later, the switching frame 701 is rotated to prevent the insects from escaping. Then the collection can 7 is disassembled to remove the insects.
[0034] Please see Figure 5 In this embodiment, a rotating rod 12 is provided on the side of the test box 2 near the magnetic field generating device 3. Both ends of the rotating rod 12 are rotatably connected to support plates. Two second winding reels 13 are fixedly connected to the outside of the rotating rod 12. A reset rope 14 is wound and fixedly connected to the outside of the two second winding reels 13. The reset rope 14 passes through the test box 2 and is fixedly connected to the driving baffle 8.
[0035] The test box 2 is rotatably connected to the side near the magnetic field generating device 3, with a directional wheel 17 for guiding the reset rope 14. A fixed cylinder 15 is fixedly connected to the outside of the support plate, and a reset torsion spring 16 is fixedly connected between the fixed cylinder 15 and the rotating rod 12.
[0036] Specifically, after the insects are driven away, the driving barrier 8 needs to be reset. At this time, the first winding reel 11 is released, and the reset torsion spring 16, which is fixedly connected between the rotating rod 12 and the fixed cylinder 15, is reset. The reset torsion spring 16 pulls the rotating rod 12 to rotate, and the reset torsion spring 16 pulls the fixedly connected second winding reel 13 to rotate and wind up. At this time, the second winding reel 13 drives the reset rope 14 fixed on the outside to pull the driving barrier 8 to reset, in preparation for the next test, and at the same time ensures the tension of the reset rope 14.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
