Description

Technical Field

Detailed Implementation

[0061] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0062] In the description of this application, it should be understood that the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more features.

[0063] With the improvement of people's living standards, aquaculture has become a major trend. The existing marine fish farming industry mainly adopts extensive aquaculture methods based on aquaculture cages. During the farming process, fish may experience reduced feeding ability due to environmental factors and diseases, resulting in fish of varying sizes and affecting the final sale. Traditional fish separation technology is mainly manual, using small fishing nets to extract fish fry one by one. By changing the mesh size of the fishing net, fish of different sizes can be extracted. This method relies on manual screening and cannot be automated by machines, resulting in slow fish screening and increased labor intensity for workers. At the same time, the fishing net comes into direct contact with the fish and scratches their scales, increasing the incidence of disease. This method is quite damaging to the fish and cannot separate diseased fish during the separation process.

[0064] In view of this, embodiments of this application provide a detection device for a plate-and-shell heat exchanger to overcome at least one of the above-mentioned technical problems.

[0065] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment provides a fish sorting device, including a box 10, a diversion component 20, and a screening component 40. The box 10 has a fish channel 30. When the box 10 is placed underwater for use, a fish suction pump can draw fish into the box 10, allowing the fish to swim along the fish channel 30. The diversion component 20 is disposed within the fish channel 30 and connected to the box 10. The diversion component 20 divides the fish channel 30 into multiple fish-separating channels 31, which are arranged circumferentially along the diversion component 20. That is, as the fish swim along the fish channel 30, they enter different fish-separating channels 31, undergoing initial separation. The fish in each fish-separating channel 31 do not interfere with each other, and the number of fish in each channel is reduced, which is beneficial for sorting the fish in each channel. The fish are screened; the screening component 40 is connected to the tank 10 and the diversion component 20. The screening component 40 has multiple screening channels 50, which are respectively connected to multiple fish separation channels 31. That is to say, the fish will enter the corresponding screening channel 50 along the fish separation channel 31. The screening component 40 further screens and separates the fish. This process does not require manual intervention. The device automatically screens the fish. The screening speed is fast. During the screening process, the fish are in each channel filled with water, which will not cause the fish to suffer from hypoxia. At the same time, the screening component 40 can identify and screen fish of different sizes, as well as sick fish.

[0066] Please see Figure 1In some embodiments, the fish channel 30 has an inlet end 32 and an outlet end 33 that are arranged opposite to each other, and the screening component 40 is disposed at the outlet end 33. The accommodating space of the fish channel 30 narrows along the direction from the inlet end 32 to the outlet end 33. Specifically, the fish enter the box 10 through the inlet end 32 of the fish channel 30 and then exit from the outlet end 33. Since the screening component 40 is connected to the outlet end 33, after the fish exits through the outlet end 33, it will enter the corresponding screening component 40 and be screened by the screening component 40.

[0067] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the fish channel 30 includes a first channel 34 and a second channel 35 that are connected to each other; the diversion component 20 includes a main body 21 and a plurality of partition plates 22. The main body 21 is disposed in the first channel 34 and the second channel 35. The main body 21 has an inner cavity 217 and multiple perforations 218 communicating with the inner cavity 217. The multiple perforations 218 are respectively connected to multiple fish-dividing channels 31. Specifically, the interior of the main body 21 is a hollow structure, forming an inner cavity 217. Multiple perforations 218 can be opened at one end of the main body 21, and these perforations 218 are connected to the inner cavity 217. Multiple partition plates 22 are disposed in the second channel 35 and connected to the main body 21 and the box body 10. The multiple partition plates 22 can divide the second channel 35 into multiple fish-dividing channels 31. The multiple perforations 218 correspond one-to-one with the multiple fish-dividing channels 31, that is, each perforation 218 connects the corresponding fish-dividing channel 31 to the inner cavity 217. Preferably, there can be six partition plates 22, which can divide the second channel 35 into six fish-dividing channels 31, thereby dividing the fish into six groups. Of course, the number of partition plates 22 is not necessarily six, and can be set as needed.

[0068] Please see Figure 1 and Figure 2In some embodiments, the main body 21 includes a first diversion section 211, a second diversion section 212, a third diversion section 213, and a guide section 214. Multiple partition plates 22 are arranged circumferentially around the first diversion section 211, meaning multiple partition plates 22 surround the periphery of the first diversion section 211. The first diversion section 211 is connected to the tank 10 via multiple partition plates 22 to form multiple fish-dividing channels 31, thereby dividing the fish entering the tank 10 through the inlet end 32 into multiple groups. The second diversion section 212 is connected to the side of the first diversion section 211 away from the screening component 40. The third diversion section 213 is connected to the side of the second diversion section 212 away from the screening component 40. The guide section 214 is connected to the side of the third diversion section 213 away from the screening component 40. The first diversion section 211, second diversion section 212, third diversion section 213, and guide section 214 are all located on the side of the third diversion section 213 away from the screening component 40. The maximum radial dimensions of the first diversion section 211, the second diversion section 212, the third diversion section 213, and the guide section 214 decrease sequentially. That is, along the direction of the fish swimming, i.e., along the direction from the inlet end 32 to the outlet end 33, the maximum radial dimensions of the guide section 214, the third diversion section 213, the second diversion section 212, and the first diversion section 211 increase sequentially. This makes the gap between the guide section 214, the third diversion section 213, the second diversion section 212, the first diversion section 211 and the box 10 gradually decrease. When the fish pass through, the gap will also gradually decrease until it can accommodate a single fish, which is beneficial for the separation and screening of fish.

[0069] Please see Figure 2 In some embodiments, the first diversion section 211 includes a first tube 2112, a first guide member 2111, and a first plate 2113. Multiple partition plates 22 are arranged circumferentially along the first tube 2112, and the first tube 2112 is connected to the housing 10 via the partition plates 22 to divide the second channel 35 into multiple fish-dividing channels 31. The first guide member 2111 is connected to the side of the first tube 2112 away from the screening component 40. The surface of the first guide member 2111 is arc-shaped. When a school of fish passes through, the swimming space changes and decreases, allowing the first guide member 2111 to guide the fish. Simultaneously, the first guide member 2111 can be made of rubber, and when the fish collide with the first guide member... When the first flow guide 2111 is in the flow path, the relatively soft first flow guide 2111 can provide a certain buffer for the fish and prevent them from being injured by collisions. The first flow guide 2111 has a first notch, which connects the first channel 34 and the inner cavity 217. Some fish can enter the inner cavity 217 through the first notch and swim along the inner cavity 217. Afterwards, they can enter the corresponding fish distribution channel 31 through the perforation 218. The first plate 2113 is located inside the first tube 2112 and the first flow guide 2111 and is connected to the first tube 2112 and the first flow guide 2111.

[0070] Please see Figure 2In some embodiments, the second diversion section 212 includes a second tube 2122, a second guide member 2121, and a second plate 2123. The second tube 2122 is connected to the side of the first guide member 2111 away from the screening component 40. As shown in the figure, the radial dimension of the second tube 2122 is smaller than the radial dimension of the first tube 2112. The first guide member 2111 serves as a transition structure between the two, allowing the fish to swim from the outside of the second tube 2122 to the outside of the first tube 2112. The second guide member 2121 is connected to the side of the second tube 2122 away from the screening component 40. The surface of the second guide member 2121 is arc-shaped. When the fish pass by, the swimming space changes and decreases, allowing the second guide member 2121 to guide the fish. Simultaneously, the second guide member 2121... The flow element 2121 can be made of rubber. When the fish collide with the second flow element 2121, the relatively soft second flow element 2121 can provide a certain buffering effect to prevent the fish from being injured by the collision. The second flow element 2121 has a second notch, which connects the first channel 34 and the inner cavity 217. Some fish can enter the inner cavity 217 through the second notch and swim along the inner cavity 217. Afterwards, they can enter the corresponding fish distribution channel 31 through the perforation 218. The second plate 2123 is located inside the second tube 2122 and the second flow element 2121 and is connected to the second tube 2122 and the second flow element 2121.

[0071] Please see Figure 2 In some embodiments, the third diversion section 213 includes a third tube 2132, a third guide member 2131, and a third plate 2133. The third tube 2132 is connected to the side of the second guide member 2121 away from the screening component 40. As shown in the figure, the radial dimension of the third tube 2132 is smaller than that of the second tube 2122. The second guide member 2121 serves as a transition structure between the two, allowing the fish to swim from the outside of the third tube 2132 to the outside of the second tube 2122. The third guide member 2131 is connected to the side of the third tube 2132 away from the screening component 40. The surface of the third guide member 2131 is arc-shaped. When the fish pass by, the swimming space changes and decreases, causing the third guide member 2131 to... It can guide the fish. At the same time, the third guide member 2131 can be made of rubber. When the fish collide with the third guide member 2131, the relatively soft third guide member 2131 can provide a certain buffering effect and prevent the fish from being injured by the collision. The guide section 214 is connected to the side of the third guide member 2131 away from the screening component 40. The guide section 214 performs the initial separation of the fish entering the box 10. The third plate 2133 is located inside the third tube 2132 and the third guide member 2131, and is connected to the third tube 2132 and the third guide member 2131.

[0072] The flow guiding section 214 includes a flow guiding cover 2141 and a flow guiding tube body 2142. The flow guiding tube body 2142 is connected to the third flow guiding member 2131, and the flow guiding cover 2141 is connected to the side of the flow guiding tube body 2142 away from the third flow guiding member 2131. The flow guiding cover 2141 is arc-shaped to prevent the device from damaging the fish. Figure 2 It can be seen that the radial dimension of the guide tube 2142 is smaller than that of the third tube 2132. The third guide member 2131 serves as a transition structure between the two, allowing the fish to swim from the outside of the guide tube 2142 to the outside of the third tube 2132.

[0073] Please see Figure 2 In some embodiments, the first tube 2112, the first guide 2111, the second tube 2122 and the second guide 2121 are connected sequentially along the direction from the outlet end 33 to the inlet end 32 to form an inner cavity 217, which allows some fish to pass through the inside of the inner cavity 217.

[0074] Please see Figure 2 and Figure 3 In some embodiments, the main body 21 further includes a first buffer section 215 and a second buffer section 216. The first buffer section 215 is located inside the first guide member 2111 and the second tube 2122, and is respectively connected to the first guide member 2111 and the second tube 2122. Specifically, when the fish swim from the outside of the second tube 2122 to the outside of the first tube 2112, the space for accommodating the fish will gradually decrease, and crowding will occur between the second tube 2122 and the first tube 2112, which may even cause the fish to be injured. The first buffer section 215 can open the first gap, allowing some fish to enter the inner cavity 217 through the first gap and enter the corresponding fish distribution channel 31 through the perforation 218. The second buffer section 216 is located inside the second guide member 2111 and the second tube 2122. The first buffer 215 and the second buffer 216 are located inside the flow element 2121 and the third tube 2132, respectively connected to the second flow element 2121 and the third tube 2132. Specifically, when the fish swim from the outside of the third tube 2132 to the outside of the second tube 2122, the space for accommodating the fish gradually decreases, and crowding will occur between the third tube 2132 and the second tube 2122, which may even cause the fish to be injured. The second buffer 216 can open the second gap, allowing some fish to enter the inner cavity 217 through the second gap and enter the corresponding fish distribution channel 31 through the perforation 218. The first buffer 215 and the second buffer 216 help to alleviate the crowding of fish inside the device.

[0075] Please see Figure 2 and Figure 3In some embodiments, the first buffer portion 215 includes a first sensing element 2151, a first cover sheet 2154, and a first magnetic suction element 2153. The first sensing element 2151 is located inside and connected to the second tube 2122; the first cover 2154 covers the first notch, and one side of the first cover 2154 is connected to the second tube 2122; a first magnetic sheet 2152 is provided on the side of the first cover 2154 facing the first plate 2113; a first magnetic attractor 2153 is connected to the first plate 2113 and is arranged opposite to the first magnetic sheet 2152; preferably, the first sensing element 2151 can be a varistor, the first magnetic attractor 2153 can be an electromagnet, and the first cover 2154 can be a rubber component; the surface of the varistor can be flush with the outer surface of the second tube 2122, and the varistor is located at the connection between the second tube 2122 and the first guide element 2111. When the fish pass through the second tube 2122... At the connection point between the second tube 2122 and the first guide member 2111, congestion may occur due to changes in the accommodating space. When the pressure exerted by the fish on the varistor reaches a certain value, the first magnetic element 2153 will generate a magnetic attraction force, which can attract the first magnetic sheet 2152. The first magnetic sheet 2152 is connected to the first cover plate 2154. When the magnetic attraction force is greater than the bending resistance of the first cover plate 2154, the first cover plate 2154 will bend, thereby opening the first gap of the cover. At this time, some fish can enter the inner cavity 217 through the opened first gap and swim along the inner cavity 217. Then, they enter the corresponding fish distribution channel 31 through the perforation 218, thus alleviating the congestion of fish at the connection point between the second tube 2122 and the first guide member 2111.

[0076] Please see Figure 2 and Figure 3In some embodiments, the second buffer portion 216 includes a second sensing element 2161, a second cover sheet 2164, and a second magnetic suction element 2162. The second sensing element 2161 is located inside and connected to the third tube 2132; the second cover 2164 covers the second notch, and one side of the second cover 2164 is connected to the third tube 2132; a second magnetic sheet 2163 is provided on the side of the second cover 2164 facing the second plate 2123; the second magnetic attractor 2162 is connected to the second plate 2123 and is opposite to the second magnetic sheet 2163; preferably, the second sensing element 2161 can also be a varistor, the second magnetic attractor 2162 can also be an electromagnet, and the second cover 2164 can also be a rubber component; the surface of the varistor can be flush with the outer surface of the third tube 2132, and the varistor is located at the connection between the third tube 2132 and the second guide element 2121, so that the fish can pass through the third tube. At the connection between the third tube 2132 and the second guide member 2121, congestion may occur due to changes in the accommodating space. When the pressure exerted by the fish on the varistor reaches a certain value, the second magnetic element 2162 will generate a magnetic attraction force, which can attract the second magnetic sheet 2163. The second magnetic sheet 2163 is connected to the second cover plate 2164. When the magnetic attraction force is greater than the bending resistance of the second cover plate 2164, the second cover plate 2164 will bend, thereby opening the second opening of the cover. At this time, some fish can enter the inner cavity 217 through the opened second opening and swim along the inner cavity 217. Then, they enter the corresponding fish distribution channel 31 through the perforation 218, thus alleviating the congestion of fish at the connection between the third tube 2132 and the second guide member 2121.

[0077] Please see Figure 1 , Figure 5 and Figure 6 In some embodiments, the screening component 40 includes a fish-separating tube 41, a detection unit 42, and a classification unit 43. The fish-separating tube 41 is connected to the housing 10 and the diversion component 20. A screening channel 50 is formed inside the fish-separating tube 41, and the screening channel 50 is correspondingly connected to the fish-separating channel 31 to allow the fish to enter the screening channel 50. The detection unit 42 is connected to the fish-separating tube 41 for detecting the fish. The classification unit 43 is connected to the side of the fish-separating tube 41 away from the housing 10, and is connected to the fish-separating tube 41 for classifying the fish. Specifically, the number of screening components 40 is the same as the number of fish-separating channels 31. The fish-separating channels 31 are connected to the screening channels 50 in the fish-separating tube 41. Fish passing through the fish-separating channels 31 enter the fish-separating tube 41 one by one in sequence, which facilitates the detection unit 42 to detect the size and health status of individual fish. After detection, the fish can be classified by the classification unit 43, allowing fish of different size ranges and diseased fish to enter different areas.

[0078] Please see Figure 1 , Figure 5 and Figure 6 In some embodiments, the detection unit 42 includes an information collector 421, a controller 422, and a counter 423. The information collector 421 is connected to the fish-distributing tube 41 and is used to acquire images of the target object. The information collector 421 has a signal processing terminal for processing the acquired information. The controller 422 is connected to the information collector 421 and has a signal receiving terminal and a signal output terminal. The signal receiving terminal receives the signal processed by the signal processing terminal, and the signal output terminal outputs a signal. The counter 423 is connected to the fish-distributing tube 41 and electrically connected to the controller 422 for counting the fish. Specifically, the information collector 421 can be a monocular camera, and the connection between the monocular camera and the fish-distributing tube 41 is made of transparent glass to facilitate the monocular camera's observation of the fish passing through the fish-distributing tube 41. Taking photos involves a monocular camera connected to a computer on the water surface via a cable, as the fish enters the pipe in a straight line. The computer can quickly identify the individual fish images captured by the monocular camera, determine the fish's length, calculate its weight using a weight calculation formula, and identify the fish's physiological characteristics using image recognition and deep learning algorithms. For example, if the fish is diseased, it will show signs such as redness or localized rotting, thus screening for diseased fish. The computer then outputs corresponding signals to the controller 422, enabling the controller 422 to control subsequent processes, screening and classifying the fish. Meanwhile, the counter 423 counts the number of fish that pass through.

[0079] Please see Figure 1 , Figure 5 and Figure 6 In some embodiments, the sorting unit 43 includes a carrier 431 connected to the fish-separating tube 41, allowing fish passing through the fish-separating tube 41 to enter the carrier 431. The carrier 431 has a cylindrical structure, and a plurality of fish-separating openings 432 are provided at the end of the carrier 431 away from the fish-separating tube 41. Valves are provided at the fish-separating openings 432, and the valves are configured to receive signals output from a signal output terminal and control the opening and closing of the fish-separating openings 432 to filter the fish. Preferably, the carrier 431 is generally provided with Four fish separation ports 432 are provided. Three of the fish separation ports 432 can separate fish of different weight ranges, and the weight range can be adjusted. The fourth fish separation port 432 can separate diseased fish. Specifically, each fish separation port 432 is equipped with a valve for closing and opening the fish separation port 432. When the valve receives the corresponding signal from the controller 422, the corresponding valve opens, allowing the fish to be detected by the detection unit 42 to pass through the corresponding fish separation port 432, thereby completing the classification of the fish group.

[0080] Since the entire sorting process is completed inside the various channels of the device, and each channel is filled with water, the fish are not exposed to the air during the sorting process, thus preventing oxygen deprivation. Therefore, the device can be used in water or on the shore, making it amphibious and preventing oxygen deprivation in the fish. In addition, the radius of the fish-separating inlet 432 and the corresponding valve on the device can be adjusted as needed to adapt to the sorting of fish of different weights and sizes.
