Description

Technical Field

[0001] The present invention relates to the field of aquaculture, and in particular to a parasite treatment device and method for aquaculture. Background Art

[0002] Aquatic products are popular with humans because of their delicious taste and rich nutrition. However, most aquatic products contain more or less parasites that are harmful to the human body, such as nematodes, flukes and tapeworms. Common nematodes include Anisakis, Angiostrongylus cantonensis and Gnathostomus sutsugamushi. Flukes are mainly liver flukes and lung flukes, and tapeworms are mainly Spirochaete mansoni. These parasites live in the internal organs, body surface or muscles of aquatic products. For parasites in the internal organs, they can be prevented by removing the internal organs of aquatic products and not eating them. For parasites on the body surface, they can be prevented by fully washing aquatic products. For parasites living in muscles, there is currently no good way. They can only be killed by high-temperature cooking. Although low-temperature deep freezing can also kill parasites in muscles, the reliability is not high. For some parasites, the killing rate of low-temperature deep freezing cannot be guaranteed to be 100%. Therefore, for consumers who like to eat raw aquatic products (such as sashimi), the risk of infection with parasites is still relatively high.

[0003] Where there is a market, there is business opportunity. In order to fully tap the consumer market for raw aquatic products, increase economic income, and solve the worries of consumers who like to eat raw aquatic products, aquaculture farmers usually add chemicals to the water in the existing technology to solve the problem of parasites in aquatic products. However, the chemicals not only pollute the water environment, but also detect drug residues in aquatic products, which is harmful to human health. Moreover, after a few years of use, parasites develop drug resistance and the insecticidal effect is greatly reduced. Summary of the invention

[0051] The present invention proposes a parasite treatment device for aquaculture, which uses machine vision technology to identify parasites in water and on the surface of aquatic products, and then uses lasers to quickly eliminate the parasites, without polluting the water body, and the parasites do not develop drug resistance. No drug residues will be detected in aquatic products. The device is environmentally friendly and healthy, with a fast insecticide speed and high efficiency, and a good insecticide effect. It effectively purifies the water body and improves the water quality. The parasites in the water are greatly reduced, and the probability of aquatic products being infected with parasites is greatly reduced, which solves the worries of consumers who like to eat raw aquatic products.

[0052] Specifically, in one embodiment of the invention, Figure 1 As shown, the parasite treatment equipment for aquaculture includes a mounting frame 1, a large rotating drum 7 and a second motor 47. The upper end of the large rotating drum 7 is rotatably connected to the mounting frame 1, and the lower end extends into the water. The second motor 47 is fixedly connected to the mounting frame 1 and is transmission-connected to the large rotating drum 7 for driving the large rotating drum 7 to rotate.

[0053] In this embodiment, the lower end of the large rotating drum 7 is sealed and the upper end is open. This design facilitates the installation of electrical equipment in the large rotating drum 7 and prevents water from entering the large rotating drum 7 from the lower end.

[0054] In this embodiment, the mounting frame 1 can float on the water surface, for example Figure 1 and Figure 3 It is shown that an air bag 3 is fixed on the lower surface of the mounting frame 1, and the mounting frame 1 floats on the water surface with the help of the air bag 3. The design of the mounting frame 1 floating on the water surface can prevent water from entering the large rotating drum 7 from the upper end of the large rotating drum 7 and damaging the electrical equipment in the large rotating drum 7. Figure 3 and Figure 4 As shown, the upper end of the large drum 7 is located above the water level 4.

[0055] Specifically, Figure 3 and Figure 4As shown, a hanging plate 6 is rotatably installed on the upper end of the large rotating drum 7, and the hanging plate 6 is detachably fixed to the mounting frame 1 through multiple connecting rods 5. A retaining ring 8 is detachably fixed to the upper end of the large rotating drum 7, and the lower surface of the retaining ring 8 is crimped to the upper surface of the hanging plate 6. The retaining ring 8 is used to prevent the hanging plate 6 from moving up and separating from the large rotating drum 7. With the help of the hanging plate 6, the large rotating drum 7 is suspended below the mounting frame 1 and rotates.

[0056] In this embodiment, if Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the large rotating drum 7 is provided with a visual camera 15, a searchlight 16, a frame 34, and a motor 27. The visual camera 15 and the searchlight 16 are detachably connected to the large rotating drum 7. The searchlight 16 is used to illuminate the dark underwater environment to facilitate the visual camera 15 to take pictures. The visual camera 15 transmits the taken high-definition photos to the controller for analysis and processing. The controller accurately and quickly identifies and locates the parasites in the photos based on the image analysis and processing recognition algorithm preset therein, and finally controls the laser 35 to emit laser pulses to the parasites to eliminate the parasites. The energy of the laser pulse needs to be set to a range that can eliminate the parasites but does not harm the aquatic products.

[0057] In this embodiment, if Figure 5 As shown, preferably, there are two visual cameras 15, and they are located on the upper and lower sides of the searchlight 16. When the searchlight 16 is turned on, an irradiation area 17 is formed in the dark underwater. The area where the photographing areas 18 of the two visual cameras 15 overlap with the irradiation area 17 is the insecticidal area 19. The parasites in the insecticidal area 19 can be identified by the controller, and then the laser 35 is used to emit laser pulses to them to kill them.

[0058] In this embodiment, the frame 34 is rotationally connected to the large rotating drum 7, and the motor 1 27 is transmission-connected to the frame 34 for driving the frame 34 to rotate around the large rotating drum 7. A laser 35 and a motor 36 are provided on the frame 34, and the motor 36 is transmission-connected to the laser 35 for driving the laser 35 to swing up and down. This design enables the laser 35 to emit laser pulses in any direction to eliminate parasites around the large rotating drum 7.

[0059] Specifically, Figure 2 , Figure 6 and Figure 7 As shown, the large rotating drum 7 is equipped with an outer rotating ring 31 for external rotation, the outer rotating ring 31 is fixed with an armature 33 and the frame 34, the laser 35 is hinged on the frame 34, the motor three 36 is fixed on the frame 34, and the output shaft of the motor three 36 is transmission-connected with the laser 35 for driving the laser 35 to swing up and down to change the emission direction of the laser pulse.

[0060] Furthermore, in order to make the outer rotating ring 31 rotate stably and reliably, as Figure 2 , Figure 6 and Figure 7 As shown, both upper and lower ends of the outer rotating ring 31 are provided with retaining rings 32 , and the retaining rings 32 are also rotatably connected to the large rotating drum 7 .

[0061] In this embodiment, if Figure 6 As shown, an annular groove 29 is provided on the inner wall of the large rotating cylinder 7 in an area opposite to the outer rotating ring 31, and a magnet 30 is slidably installed in the annular groove 29, that is, the magnet 30 rotates on the inner wall of the large rotating cylinder 7, and the magnet 30 tightly adsorbs the armature 33, so the sliding of the magnet 30 can attract the armature 33 to move synchronously, that is, the magnet 30 rotates on the inner wall of the large rotating cylinder 7 and drives the outer rotating ring 31 to rotate synchronously with the help of the armature 33, and the rotation of the outer rotating ring 31 drives the laser 35 to rotate around the large rotating cylinder 7, thereby changing the emission direction of the laser pulse.

[0062] In this embodiment, the magnet 30 is a permanent magnet 30 or an electromagnet.

[0063] In this embodiment, if Figure 6 As shown, the magnet 30 is fixedly connected to the inner rotating ring 25, the inner rotating ring 25 is coaxially arranged with the outer rotating ring 31, the inner rotating ring 25 is rotationally connected to the positioning ring 24, the positioning ring 24 is fixedly connected to the mounting frame 1, the positioning ring 24 is fixedly provided with the motor 27, the inner rotating ring 25 is fixedly provided with a gear ring 26, the motor 27 is provided with an angle sensor 44 and a gear 28 transmission-connected with the gear ring 26, after the motor 27 is started, the gear ring 26 can be driven to rotate by the gear 28, the gear ring 26 rotates to drive the inner rotating ring 25 to rotate, the inner rotating ring 25 rotates to drive the magnet 30 to rotate on the inner wall of the large rotating drum 7, the angle sensor 44 on the motor 27 is used to detect the rotation angle of the motor 27, and then judge the position of the laser 35 on the outer wall of the large rotating drum 7 according to its rotation angle.

[0064] In this embodiment, if Figure 6 As shown, a slip ring 20 is coaxially arranged in the large rotating drum 7, and the slip ring 20 is fixedly connected to the mounting frame 1. The slip ring 20 is used to transmit electric energy and control signals to the visual camera 15, the searchlight 16, the laser 35 and the motor 36. Because the visual camera 15, the searchlight 16, the laser 35 and the motor 36 rotate with the large rotating drum 7, the slip ring 20 can be provided to ensure that the visual camera 15, the searchlight 16, the laser 35 and the motor 36 can be normally connected to the controller signal and electrically connected to the battery 14, as shown in FIG. Figure 3 and Figure 4As shown, the battery 14 for powering the parasite treatment equipment for aquaculture can be detachably fixed in the large rotating drum 7, and control devices such as the controller for data analysis and processing, the controller for controlling the operation of the motor, and the controller for controlling the operation of the laser 35 are all arranged in the control box 13, and the control box 13 can be detachably fixed in the large rotating drum 7.

[0065] Specifically, Figure 5 and Figure 6 As shown, a positioning plate 21 is fixedly disposed in the slip ring 20 , and the positioning plate 21 and the suspension plate 6 are detachably fixedly connected via an upper fixed shaft 9 .

[0066] In this embodiment, if Figure 6 As shown, a second positioning plate 23 detachably connected to a positioning ring 24 is provided in the large rotating drum 7 . The second positioning plate 23 is detachably connected to the first positioning plate 21 via a lower fixed shaft 22 . The second positioning plate 23 is slidably connected to the inner wall of the large rotating drum 7 .

[0067] In this embodiment, if Figure 6 As shown, the positioning plate 23 is rotatably mounted with a moving shaft 10 and an intermediate wheel 38, and the moving shaft 10 is provided with a speed sensor 12, and the speed sensor 12 is fixedly connected to the suspension plate 6, as shown in FIG. Figure 4 As shown, the speed sensor 12 is used to detect the speed of the moving shaft 10, and obtain the rotation angle of the large rotating drum 7 according to the speed of the moving shaft 10. The upper end of the moving shaft 10 movably passes through the positioning plate 21 and the hanging plate 6 and then extends out of the large rotating drum 7 and is fixedly connected with the fan 11. When the wind blows the fan 11 to cause the fan 11 to rotate, the fan 11 can drive the moving shaft 10 to rotate. Figure 8 As shown, the lower end of the movable shaft 10 is provided with a spline 40, and a gear 39 is axially mounted on the spline 40 for upward and downward sliding. The gear 39 can mesh with the intermediate wheel 38. The rotation of the movable shaft 10 drives the gear 39 to rotate, and then drives the intermediate wheel 38 to rotate. Figure 6 As shown, a gear ring 3 37 is coaxially fixed on the inner wall of the large rotating drum 7, and the intermediate wheel 38 is meshed with the gear ring 37. Therefore, the rotation of the driving shaft 10 drives the gear ring 3 37 to rotate, that is, drives the large rotating drum 7 to rotate. At this time, the large rotating drum 7 is driven to rotate by the fan 11.

[0068] Further, such as Figure 6 As shown, a slide 41 is provided just below the gear 39. The slide 41 can be moved upward and sleeved outside the spline 40 without contacting the spline 40. A lifting device 42 is provided below the slide 41. The lifting device 42 is fixedly connected to the positioning plate 23. The lifting device 42 is used to push the slide 41 up and down to drive the gear 39 up and down to engage or disengage with the intermediate wheel 38; Figure 8As shown, a small rotating cylinder 43 is installed for external rotation of the slide cylinder 41, and a gear 49 is coaxially fixedly arranged on the upper end of the small rotating cylinder 43, and the gear 49 can mesh with the intermediate wheel 38, and a gear ring 2 45 is coaxially fixedly arranged on the lower end of the small rotating cylinder 43, and a motor 2 47 is fixedly arranged on the slide cylinder 41, and a rotation angle sensor 44 and a gear 2 46 meshing with the gear ring 2 45 are arranged on the motor 2 47, and the rotation of the motor 2 47 drives the gear ring 2 45 to rotate through the gear 2 46, and the rotation of the gear ring 2 45 drives the gear 49 to rotate through the small rotating cylinder 43, and the rotation angle sensor 44 on the motor 2 47 is used to detect the rotation angle of the motor 2 47, so as to judge the rotation angle of the large rotating cylinder 7 according to the detection data; as shown Figure 8 As shown, the lifting device 42 pushes the slide 41 upward to push the gear three 39 open and separate it from the intermediate wheel 38, and at the same time makes the gear four 49 mesh with the intermediate wheel 38, and drives the large rotating drum 7 to rotate with the help of the motor two 47. After the subsequent fan 11 rotates, the lifting device 42 is reset to drive the gear four 49 to descend and separate from the intermediate wheel 38, and at the same time, the gear three 39 slides down along the spline 40 to resume meshing with the intermediate wheel 38.

[0069] The present embodiment adopts the method of using motor 2 47 and fan 11 to cooperate in driving the large rotating drum 7 to rotate, which can effectively utilize wind energy, reduce energy consumption, save energy and protect the environment. Specifically, when there is wind, wind energy is used to drive the large rotating drum 7 to rotate, and when there is no wind, the large rotating drum 7 is driven to rotate with the help of motor 2 47.

[0070] Furthermore, Figure 1 As shown, the mounting frame 1 is provided with a solar panel 2. This design can fully utilize solar energy to generate electricity, further reduce the energy consumption of the parasite treatment equipment for aquaculture, and reduce electricity costs.

[0071] In this embodiment, if Fig. 9 As shown, a plurality of toothless areas 48 are formed by removing a plurality of teeth from the outer circumferential surfaces of the gear three 39 and the gear four 49, and the plurality of toothless areas 48 are centrally symmetrically distributed. With this design, even if the gear three 39 and the gear four 49 rotate continuously, the intermediate wheel 38 rotates only when it is meshed with the gear three 39 and the gear four 49. After the toothless areas 48 of the gear three 39 and the gear four 49 contact the teeth of the intermediate wheel 38, the intermediate wheel 38 does not rotate. With this design, the large drum 7 stops rotating after rotating for β°, rotates again for β° after a period of time, and then continues to stop rotating for a period of time. During the period of time when the large drum 7 stops rotating, the searchlight 16 is turned on, the visual camera 15 takes pictures, the controller analyzes and processes the pictures, and obtains the position of the parasite, and the laser 35 emits laser pulses to the parasite to kill the parasite.

[0072] In this embodiment, the specific value of β is determined according to the size of the insecticidal area 19. By rotating the large drum 7 by multiple β angles, all parasites around the large drum 7 can be eliminated. In order to improve the quality of parasite elimination and reduce the probability of missed elimination, the large drum 7 can rotate multiple times to repeatedly scan and eliminate the waters around it.

[0073] The present invention also proposes a method for treating parasites for aquaculture, which uses the aforementioned parasite treatment equipment for aquaculture to perform the following steps:

[0074] S1, turn on the searchlight 16 to form an irradiation area 17 underwater;

[0075] S2, taking pictures in the irradiation area 17 by the visual camera 15;

[0076] S3. The controller analyzes and processes the photo based on the built-in recognition algorithm, identifies the parasites in the photo and obtains their positions. The recognition algorithm in the controller uses typical statistical classification and self-learning classification methods. In the early stage, specimens of various parasites are obtained in the waters to establish a parasite image feature classification model database, which specifically includes the rectangular area describing the template range, duty cycle, spatial histogram, spatial information distribution entropy and external contour, and then introduces the secondary edge area filtering mechanism to realize the parasite shape recognition of the microscopic image, with high recognition accuracy and reliability.

[0077] S4, control the laser 35 to emit laser pulses to the location of the parasite to eliminate the parasite. After obtaining the location of the parasite in step S3, control the motor 1 27 and the motor 3 36 to rotate, and use the angle sensor 44 to detect the rotation angle of the motor 1 27 and the motor 3 36, so that the controller can accurately determine the position of the laser 35 and ensure that the laser 35 can correctly emit laser pulses to the location of the parasite.

[0078] S5, control the large rotating drum 7 to rotate β° and then repeat steps S1-S4, 0<β<180. After the insecticide is completed in an area on one side of the large rotating drum 7, the motor 2 47 or the fan 11 drives the large rotating drum 7 to rotate β and then kill insects in another area on the side of the large rotating drum 7. Repeating this process multiple times can make the large rotating drum 7 rotate one circle, and complete the work of disinfecting parasites in all waters around the large rotating drum 7.

[0079] In this embodiment, the method for controlling the rotation of the large drum 7 in S5 is:

[0080] Obtaining the rotation speed V1 of the moving shaft 10, this step can be achieved with the help of the rotation speed sensor 12;

[0081] When the gear 39 is meshed with the intermediate wheel 38, if V1=0 and lasts for t1 time, the controller controls the lifting device 42 to push the gear 49 up to replace the gear 39 meshing with the intermediate wheel 38, and then the controller starts the motor 2 47, and the motor 2 47 drives the large rotating drum 7 to rotate. On the contrary, if V1≠0, or lasts for less than t1 time, the fan 11 drives the large rotating drum 7 to rotate. This design makes full use of wind energy without affecting the rotation of the large rotating drum 7 and the insecticidal efficiency of the aquaculture parasite treatment equipment, saves energy and protects the environment, and reduces electricity costs.

[0082] When the gear 49 is meshed with the intermediate wheel 38, if V1>a and lasts for t2 time, the lifting device 42 is controlled to drive the gear 39 to replace the gear 49 to mesh with the intermediate wheel 38, and the fan 11 drives the large rotating drum 7 to rotate. On the contrary, if V1≤a, or lasts for less than t2 time, the motor 2 47 continues to drive the large rotating drum 7 to rotate. a is the minimum speed at which the driving shaft 10 can drive the large rotating drum 7 to rotate after the gear 39 and the intermediate wheel 38 resume meshing. The value thereof varies with the volume of the parasite treatment equipment for aquaculture, the material of each transmission part in the large rotating drum 7, and the rotation speed of the large rotating drum 7. The specific value can be obtained by conducting a limited number of tests during actual use. When the power transmission is disconnected between gear three 39 and the intermediate wheel 38, the rotation speed of the driving shaft 10 is lower than a. Then, after the gear three 39 and the intermediate wheel 38 resume meshing, the driving shaft 10 cannot drive the large rotating drum 7 to rotate. This design ensures that the fan 11 can reliably drive the large rotating drum 7 to rotate, and there will be no problem that the driving shaft 10 cannot drive the large rotating drum 7 to rotate after the gear three 39 and the intermediate wheel 38 resume meshing due to too low wind speed, thereby affecting the insecticidal efficiency of the parasite treatment equipment for aquaculture.

[0083] Preferably, t1=5s, t2=10s.

[0084] Of course, in other embodiments, when the gear four 49 is meshed with the intermediate wheel 38, if V1>b, the lifting device 42 is controlled to drive the gear three 39 to replace the gear four 49 to mesh with the intermediate wheel 38, and the fan 11 drives the large rotating drum 7 to rotate. Otherwise, the motor 2 47 drives the large rotating drum 7 to rotate. In this method, b is the rotation speed of the driving shaft 10 when the external wind force is large (for example, above level 5 wind), which is related to the diameter of the driving shaft 10, the material, quality, and friction resistance of each transmission part in the large rotating drum 7. At this time, the rotation speed of the driving shaft 10 is fast, and it takes at least some time for the rotation speed of the driving shaft 10 to drop from b to below a. This period of time is enough for the large rotating drum 7 to rotate β° and then repeat steps S1-S4. Therefore, it can be used to drive the large rotating drum 7 to rotate. Therefore, the value b can be determined through a limited number of tests after the parasite treatment equipment for aquaculture is assembled.

[0085] In this embodiment, the controller determines whether gear three 39 or gear four 49 is engaged with the intermediate wheel 38 by detecting the stroke of the lifting device 42. When the lifting device 42 is reset, gear three 39 is engaged with the intermediate wheel 38. When the lifting device 42 is at the maximum stroke, gear four 49 is engaged with the intermediate wheel 38.

[0086] In this embodiment, considering that the external wind direction is erratic, when it is detected that the large drum 7 rotates β° and then rotates in the opposite direction to return to the previous insecticide area 19, the controller controls the visual camera 15, the searchlight 16, and the laser 35 to stop working.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
