Specific embodiments

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1

[0027] Please refer to Figure 1 , a system for evaluating the enrichment effect of herbicides on aquatic organisms. First, a simulation box is set up to simulate the environment of the area where weeding is required; among them, the simulation box is filled with water (consistent with the water area of the weeding area), and aquatic organisms (water plants) are placed in the water; the system includes: an acquisition module, a transmission module (the transmission module refers to transmitting the collected information through the network), a processing module (such as a computer), and a controller;

[0028] Among them, the evaluation method specifically includes the following steps:

[0029] In the first step, the controller controls the acquisition module to work, so that the acquisition module acquires the images of the aquatic organisms in the simulation box, and the transmission module transmits the collected information to the processing module;

[0030] Step 2: The collected aquatic organism images are displayed on the processing module. The processing module includes an image recognition module. The collected aquatic organism images are compared with normal aquatic organism images to analyze the growth status of the aquatic organisms, which is used as an evaluation index and an evaluation result is given. When there are adverse phenomena such as yellowing of the aquatic organism leaves, yellow-green patches, and non-unfolding of the leaves, it is evaluated that the herbicide will inhibit the growth of the aquatic organisms. If the above situation does not occur in the aquatic organisms, it is evaluated that the herbicide has no effect on the aquatic organisms.

[0031] It should be noted that the controller is equivalent to a switch, which closes the switch to turn on the power supply of the acquisition module, enabling it to start working and collect images of aquatic organisms.

[0032] It should also be noted that the aquatic organisms refer to waterweeds; the processing module sorts the images in chronological order according to the time of collecting information for display to the staff; the way for the staff to analyze the images is by analyzing the leaf color and leaf unfolding state of the waterweeds in the images.

[0033] Please refer to Figure 2 and Figure 5 As shown in, the acquisition module includes a connecting rod 1 and two moving wheels 2 respectively installed at both ends of the connecting rod 1. A power mechanism (such as a motor) is provided on the connecting rod 1, and the output end of the power mechanism is connected to the shaft of the moving wheel 2; a collar 3 and a mounting ring 5 are sleeved on the connecting rod 1. A first imaging device 4 (such as a camera) is provided on the collar 3. A support rod is provided on the mounting ring 5, and the bottom end of the support rod is provided with a mounting box 7. The mounting box 7 extends into the water inside the simulation box. A second imaging device (such as a camera) is provided in the mounting box 7. An observation window 13 is provided on the mounting box 7, so that the second imaging device can take pictures of the situation outside the mounting box 7 through the observation window 13.

[0034] In this embodiment, as a further optimized solution, please refer to Figure 2 As shown in, the connecting rod 1 includes a mounting rod 101. Mounting holes are formed at both ends of the mounting rod 101. A movable rod 102 is slidably inserted into the mounting holes, and a bolt for fixing the movable rod 102 is screwed on the outer wall of the mounting rod 101; by moving the movable rod 102, the length of the connecting rod can be adjusted to change the distance between the two moving wheels 2, so that the acquisition module is applicable to different usage requirements (adapting to simulation boxes of different specifications).

[0035] It should be noted that, in order to study the effects of herbicides on aquatic plants, a simulation box will be set up. Inside the simulation box, the growth waters of aquatic organisms will be simulated, and aquatic organisms will be placed. During the evaluation, herbicides will be added to the simulation box, and the collection module will be placed above the simulation box so that the moving wheels 2 of the collection module are in contact with the top edge of the simulation box. When the controller controls the collection module to work, the power mechanism works, causing the moving wheels 2 to rotate and move above the simulation box, driving the connecting rod 1 to move along. During the movement of the connecting rod 1, the first imaging device 4 passes above the simulation box and takes pictures from above the aquatic organisms. During the movement of the connecting rod 1, the support rod will drive the installation box 7 to move in the water of the simulation box, so that the second imaging device inside the installation box 7 takes pictures of the aquatic organisms from below, making the collected aquatic organism information more comprehensive, thereby increasing the accuracy of the evaluation. The captured images are transmitted to the processing module through the transmission module, and the processing module displays the captured images for the staff to view. The staff analyzes the growth status of the aquatic organisms based on the images, and thus gives an evaluation result of the enrichment of herbicides in the aquatic organisms.

[0036] It should also be noted that the collection module will regularly collect the conditions of the aquatic organisms in the simulation box to determine the growth conditions of the aquatic organisms over a period of time, so as to judge the impact of herbicides on the aquatic organisms.

[0037] In this embodiment, as a further optimized solution, please refer to Figure 2 and Figure 3 , the support rod is a telescopic rod 6 (including a telescopic mother rod and a telescopic son rod slidably inserted into the telescopic mother rod, and the telescopic son rod cannot automatically disengage from the telescopic mother rod), and an airbag 10 is provided on the installation box 7; the airbag 10 provides buoyancy for the installation box 7, so that the depth of the installation box 7 entering the water in the simulation box is constant and will not change with the water level change inside the simulation box, ensuring that the second imaging device can accurately collect information.

[0038] In this embodiment, as a further optimized solution, please refer to Figure 3 and Figure 4, an adjustment box 8 is provided on the installation ring 5. The adjustment box 8 is communicated with the airbag 10 through a connecting pipe 9. A moving plate 12 is slidably arranged in the adjustment box 8 (the moving plate 12 divides the inner cavity of the adjustment box 8 into two mutually isolated upper and lower parts). A return spring is installed between the moving plate 12 and the adjustment box 8. An eccentric wheel 11 is rotatably installed in the adjustment box 8. The eccentric wheel 11 is in contact with the top wall of the moving plate 12. A driving member (such as a motor) is installed on the adjustment box 8. The output end of the driving motor is connected to the eccentric wheel 11. When the driving member drives the eccentric wheel 11 to rotate and the shorter diameter part of the eccentric wheel 11 is in contact with the moving plate 12, the moving plate 12 will move upward under the action of the return spring, increasing the space where the adjustment box 8 is communicated with the airbag 10. Part of the air inside the airbag 10 will enter the inside of the adjustment box 8. The airbag 10 will contract due to the reduction of gas, reducing the buoyancy provided by it to the installation box 7, causing the installation box 7 to move downward. As described above, when the eccentric wheel 11 rotates and the moving plate 12 moves downward (the larger diameter area of the eccentric wheel 11 contacts the moving plate 12) and the air inside the adjustment box 8 is squeezed into the airbag 10, the inflation amplitude of the airbag 10 increases, increasing the buoyancy provided by the airbag 10 to the installation box 7, causing the installation box 7, so that the depth of the installation box 7 entering the water in the simulation box can be changed. And during the walking of the moving wheel 2, the driving member rotates (continuously rotates), causing the moving plate 12 to move up and down, causing the buoyancy provided by the airbag 10 to the installation box 7 to increase and decrease back and forth, causing the installation box 7 to move up and down, increasing the shooting range of the second imaging device. The connecting pipe 9 is a flexible pipe.

[0039] In this embodiment, as a further optimized solution, please refer to Figure 2 , the sleeve ring 3 and the installation ring 5 are respectively movably sleeved on the outer wall of the connecting rod 1. Annular grooves are provided at the connecting parts of the connecting rod 1 with the sleeve ring 3 and the installation ring 5. The sleeve ring 3 and the installation ring 5 can rotate on the outer wall of the connecting rod 1, so that when the connecting rod 1 rotates, it will not drive the sleeve ring 3 and the installation ring 5 to rotate together, ensuring the shooting angles of the first imaging device 4 and the second imaging device.

[0040] Embodiment 2

[0041] As a further optimized solution, please refer to Figure 5 , a scraping plate 14 is slidably arranged on the installation box 7 (the scraping plate 14 can move up and down). The scraping plate 14 is in contact with the outer bottom of the observation window 13. A rotating rod 15 is rotatably arranged on the installation box 7. A follower wheel 16 is provided at the end of the rotating rod 15. A pull rope 17 is wound around the outer wall of the rotating rod 15. One end of the pull rope 17 away from the rotating rod 15 is connected to the scraping plate 14. When the moving wheel 2 rotates and walks, the installation box 7 will move in the water of the simulation box, causing the follower wheel 16 to drive the rotating rod 15 to rotate and wind the pull rope 17 around the outer wall of the rotating rod 15. The pull rope 17 drives the scraping plate 14 to move upward to clean the observation window 13, ensuring the cleanliness of the observation window 13 and ensuring the normal shooting of the second imaging device.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
