[0003] Therefore, there is an urgent need for a highly automated device that can quickly measure the morphological data of fish without damaging their bodies. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a fish morphology data measuring device to solve the problem of low measurement efficiency caused by the existing manual measurement of fish morphology data.

The arrangement adjustment mechanism includes a plurality of partition plates extending toward the conveying mechanism. The plurality of partition plates are arranged side by side at intervals along a direction perpendicular to the conveying direction to form a plurality of arrangement channels on the conveying mechanism. A measuring mechanism is fixedly installed above the conveying mechanism, and the measuring mechanism extends into the arrangement channel to measure fish morphology data; A sorting mechanism connected to the output end of the conveying mechanism is used to sort the fish conveyed from each row of channels according to the fish morphology data measured by the measuring mechanism; and Several recovery bays connected to the sorting mechanism.

[0006] In a possible implementation, the measuring mechanism includes a width measuring component, which includes a detection plate and an angle detection device. The detection plate is hinged to a side partition of the arrangement channel, and the free end of the detection plate extends obliquely toward the side partition of the arrangement channel. The angle detection device detects the rotation angle of the detection plate.

[0007] In one possible implementation, an elastic element is provided between the detection plate and the connected partition plate.

[0008] In a possible implementation, the measuring mechanism further includes a lifting detection head and a detection component disposed on the lifting detection head, the lifting detection head being located within an arrangement channel, and the detection component being used to detect the thickness and / or length of the fish.

[0009] In one possible implementation, the detection component includes a measuring plate and a displacement sensor. The measuring plate is telescopically connected to the bottom of the lifting detection head, and a displacement sensor is disposed between the measuring plate and the lifting detection head so that the movement of the detection plate can drive the detection head of the displacement sensor to move.

[0010] In one possible implementation, the measuring plate is further provided with several infrared sensors arranged in a dot matrix, and the infrared sensors are arranged in an array along the length of the fish.

[0011] In one possible implementation, the lifting detection head is mounted on a lateral moving mechanism, which drives the lifting detection head to move in a direction parallel to the conveying mechanism; And / or, the lifting detection head is equipped with a positioning camera for acquiring images below, the positioning camera is connected to a controller, and the controller is used to compare the images acquired by the positioning camera with a preset reference image to determine whether there are fish below and / or whether they have moved into position.

[0012] In a possible implementation, the anesthesia chamber includes an anesthesia cavity, a fish-pushing mechanism, a filter plate, and a lifting mechanism. The filter plate is installed inside the anesthesia cavity. The filter plate is driven by the lifting mechanism to move up and down, switching between working position one and working position two. Working position two is located above the working position. When the filter plate is in working position one, the filter plate is higher than the liquid level in the anesthesia cavity. The fish-pushing mechanism and the fish outlet are installed on working position two. The fish outlet is located in the fish-pushing direction of the fish-pushing mechanism.

[0013] In one possible implementation, the anesthesia chamber is equipped with an anesthetic delivery mechanism, which includes a drug cartridge, a concentration sensor, and a metering pump. The input end of the metering pump is connected to the drug cartridge, and the output end of the metering pump is connected to the anesthesia chamber. The concentration sensor is used to detect the concentration of anesthetic in the water within the anesthesia chamber.

[0014] In a possible implementation, the arrangement adjustment mechanism further includes a mounting frame and several diverter plates. The mounting frame extends toward the conveying mechanism, and there is an attitude adjustment interval between the mounting frame and the conveying mechanism. The several diverter plates are arranged at intervals along a direction perpendicular to the conveying direction of the conveying mechanism, and the diverter plates and the partition plates are aligned along the conveying direction of the conveying mechanism.

The controller is used to control the robotic arm to grip the target fish and place it on the corresponding graded conveyor belt according to the image information acquired by the vision acquisition device.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention relates to a fish morphology data measuring device. The device anesthetizes the fish using an anesthesia chamber, making measurement easier. As the fish are transported via a conveyor, an arrangement and adjustment mechanism sorts and arranges them into a channel. Within this channel, a measuring mechanism measures the fish's morphology data. After measurement, a sorting mechanism classifies the fish based on their morphological data and assigns them to corresponding recovery chambers. This method achieves higher measurement efficiency and avoids the problem of fish struggling during measurement.

[0017] Furthermore, the width measuring component of the measuring mechanism can calculate the width of the fish by measuring the rotation angle of the detection plate in conjunction with the angle detection device, and the thickness of the fish can be obtained by measuring the plate of the lifting detection head in conjunction with the displacement sensor. The length of the fish can be easily obtained by the array of infrared sensors. Thus, the shape and size of the fish can be obtained, and the weight can be easily determined by these shape data.

[0018] Meanwhile, the anesthesia chamber, through the filter plate, lifting mechanism, and fish pushing mechanism, can anesthetize fish in the water at work station one. After anesthesia, the filter plate can be driven by the lifting mechanism to lift the fish to work station two. At this time, the water can be filtered out through the filter plate. Then, the anesthetized fish can be pushed to the conveying mechanism through the fish outlet by the fish pushing mechanism. In this way, the separation of fish and water containing anesthetic and the pushing of fish can be realized, which improves work efficiency.

[0019] In addition, the sorting mechanism controls the robotic arm through the controller, and can sort the fish according to the morphological data output from each row channel, and then transport them to the recovery chamber for recovery via the corresponding grade conveyor belt.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0023] Please refer to Figure 1-4 As shown, an embodiment of this application provides a fish morphology data measuring device, comprising: an anesthesia chamber 1, the anesthesia chamber 1 having a fish inlet and a fish outlet 12; a conveying mechanism 2 connected to the fish outlet 12 of the anesthesia chamber 1; an arrangement adjustment mechanism fixedly disposed above the conveying mechanism 2 along the conveying direction, the arrangement adjustment mechanism including a plurality of partition plates 7 extending toward the conveying mechanism 2, the plurality of partition plates 7 being arranged side by side at intervals along a direction perpendicular to the conveying direction to form a plurality of arrangement channels 8 on the conveying mechanism 2; a measuring mechanism 3 fixedly disposed above the conveying mechanism 2, the measuring mechanism 3 extending into the arrangement channels 8 to measure fish morphology data; a sorting mechanism 5 connected to the output end of the conveying mechanism 2, the sorting mechanism 5 being used to sort the fish conveyed out of each arrangement channel 8 according to the fish morphology data measured by the measuring mechanism 3; and a plurality of resuscitation chambers 6 connected to the sorting mechanism 5.

[0024] The anesthesia chamber 1 is used to anesthetize fish. Specifically, the fish entering the chamber are anesthetized by a mixture of anesthetic and water. A fish inlet hopper 13 is provided at the fish inlet, and the anesthetized fish are discharged through the fish outlet 12 to the conveying mechanism 2. The conveying mechanism 2 is used for conveying and, in conjunction with a fixed arrangement adjustment mechanism, allows the fish to be arranged and adjusted simultaneously during the conveying process to facilitate better measurement of morphological data. Preferably, the conveying mechanism 2 uses a conveyor belt 21. The arrangement adjustment mechanism mainly includes partition plates 7, which extend downwards towards the conveyor belt 21, but do not contact each other. This allows for arrangement adjustment without affecting the operation of the conveying mechanism 2. Specifically, adjacent partition plates 7 can form arrangement channels 8, each of which allows only one target size range of fish to pass through, for example, a width of 5-8 mm. Since the anesthetized fish are mainly in a supine position, the arrangement channels 8 facilitate the passage and detection of fish in this posture. The measuring mechanism 3 is also fixed and is used to measure at least one dimension of the fish, including its thickness, length, and width. The sorting mechanism 5 is used to sort the fish according to the morphological data output from each row channel 8 after grading, and then sort them into the corresponding recovery boxes for recovery and collection.

[0025] Through the above technical solution, the anesthesia chamber 1 can anesthetize the fish, making it easier to measure them while they are anesthetized. When the fish are transported by the conveying mechanism 2, the arrangement and adjustment mechanism can divert and arrange the fish into the arrangement channel 8. In the arrangement channel 8, the morphological data of the fish can be measured by the measuring mechanism 3. After measurement, the sorting mechanism 5 grades the fish based on the morphological data and sorts them into the corresponding recovery chamber 6. This allows for the measurement of the fish's morphological data, which is more efficient and avoids the problem of the fish struggling during the measurement process.

[0026] In one embodiment, the measuring mechanism 3 includes a width measuring component 31, which includes a detection plate 311 and an angle detection device (not shown in the figure). The detection plate 311 is hinged to a side partition plate 7 of the arrangement channel 8, and the free end of the detection plate 311 extends obliquely toward the side partition plate 7 of the arrangement channel 8. The angle detection device detects the rotation angle of the detection plate 311.

[0027] The measuring plate 321 for width measurement is hinged to the dividing plate. When the fish does not pass by, it is in a blocking state. When the fish passes by, it can drive the detection plate 311 to rotate. The angle detector can detect the rotation angle of the detection plate 311. The width of the fish that passed by can be calculated from the rotation angle, and thus the width data can be obtained.

[0028] To improve the accuracy of width measurement, an elastic element 312 is provided between the detection plate 311 and the connected partition plate 7. The elastic element 312 facilitates the repositioning of the detection plate 311 and improves the fit with the fish during detection, thus enhancing accuracy. The maximum rotation angle is used for calculation during the detection process. Preferably, the elastic element 312 is a spring.

[0029] Furthermore, the measuring mechanism 3 also includes a lifting detection head 32 and a detection component disposed on the lifting detection head 32. The lifting detection head 32 is located within the arrangement channel 8, and the detection component is used to detect the thickness and / or length of the fish.

[0030] The detection component can be switched between the detection position and the avoidance position via the lifting detection head 32. The detection component is used to obtain thickness and / or length data of the fish.

[0031] In a preferred embodiment of the detection component, the detection component includes a measuring plate 321 and a displacement sensor 322. The measuring plate 321 is telescopically connected to the bottom of the lifting detection head 32. The displacement sensor 322 is disposed between the measuring plate 321 and the lifting detection head 32, so that the movement of the measuring plate 321 can drive the detection head of the displacement sensor 322 to move.

[0032] The measuring plate 321 is connected to the bottom of the lifting detection head 32 via a telescopic connection, facilitating free extension and retraction. When the lifting detection head 32 descends to the detection position, the measuring plate 321 retracts due to contact with the fish, causing the detection head of the displacement sensor 322 to retract as well. Thus, the fish thickness data can be obtained by detecting displacement. It is understood that when the measuring plate 321 is in the avoidance position and not in contact with the fish during descent, it remains at its lower limit position under the influence of gravity. When the measuring plate 321 comes into contact with the fish, it retracts under the pressure of the fish's body. When the lifting detection head 32 descends to the preset detection position, the movement data from the measuring plate 321 and the displacement sensor 322 can be used to calculate the fish thickness.

[0033] In order for the lifting detection head 32 to also detect the length of the fish, the measuring plate 321 is also provided with a number of infrared sensors 324 distributed in a dot matrix, and the number of infrared sensors 324 are arranged in an array along the length direction of the fish.

[0034] By arranging the infrared sensors 324 in a dot matrix array along the length of the fish, the length of the fish can be calculated based on whether the infrared sensors 324 are blocked and the number of blocked sensors, combined with the spacing between the sensors. This allows for length measurement. Furthermore, by placing the sensors on the measuring plate 321, length measurement can be performed simultaneously with thickness measurement. In specific implementations, the infrared sensors 324 can also measure length by whether the output infrared rays are reflected or received; there are no limitations on this method.

[0035] Furthermore, to further improve the accuracy of measuring each fish, a positioning camera 323 can be installed on the lifting detection head 32 to acquire images from below. The images captured by the positioning camera 323 are compared with preset reference images to determine whether there is a fish directly below and whether the fish has moved into position. Measurement can be performed when the fish is in position. In other embodiments, the lifting detection head 32 can be mounted on a lateral movement mechanism (not shown in the figure). The position of the lifting detection head 32, which is not directly opposite the fish, can be adjusted by lateral movement to move it directly above the target fish for measurement. This lateral movement mechanism is controlled by a controller. The measuring plate 321 has through holes (not shown in the figure) for the positioning camera 323 to acquire images.

[0036] In the embodiments of this application, the anesthesia chamber 1 includes an anesthesia cavity 11, a fish pushing mechanism 14, a filter plate 15, and a lifting mechanism 16. The filter plate 15 is disposed inside the anesthesia cavity 11. The filter plate 15 is driven by the lifting mechanism 16 to move up and down to switch between working position one and working position two. The working position two is located above the working position. When the filter plate 15 is in working position one, the filter plate 15 is higher than the liquid level in the anesthesia cavity 11. The fish pushing mechanism 14 and the fish outlet 12 are disposed on working position two. The fish outlet 12 is located in the fish pushing direction of the fish pushing mechanism 14.

[0037] Fish can be anesthetized in the anesthesia chamber 11. The anesthesia method can be achieved by mixing MS-222 anesthetic solution with water. After anesthesia, the filter plate 15 at the bottom of the anesthesia chamber 11 can be lifted and moved to the second working position by a lifting mechanism 16, such as a cylinder. The filter plate 15 is on the same straight line as the fish pushing mechanism 14 and the fish outlet 12 at the second working position. The fish pushing mechanism 14, formed by the push plate and the hydraulic cylinder, can push the fish on the aluminum plate from the fish outlet 12 to the conveying mechanism 2. In this way, automatic anesthesia and separation of fish from water can be achieved and the fish can be transported to the conveying mechanism 2, thereby improving work efficiency.

[0038] To facilitate the preparation of anesthetics, the anesthesia chamber 1 is further provided with an anesthetic delivery mechanism 2. The anesthetic delivery mechanism 2 includes a drug box 17, a concentration sensor (not shown in the figure), and a metering pump 18. The input end of the metering pump 18 is connected to the drug box 17, and the output end of the metering pump 18 is connected to the anesthesia chamber 11. The concentration sensor is used to detect the concentration of anesthetics in the water in the anesthesia chamber 11.

[0039] The reagent cartridge 17 contains the anesthetic and is connected to a metering pump 18 via tubing. The metering pump 18 is connected to the anesthesia chamber 11 via tubing, allowing for more accurate preparation of the anesthetic as needed. The anesthetic mixed with water in the anesthesia chamber 11 anesthetizes the fish. A concentration sensor detects the concentration of the anesthetic in the liquid within the anesthesia chamber 11, enabling precise dosage control.

[0040] In other embodiments, the arrangement adjustment mechanism may further include a mounting frame 41 and a plurality of diverter plates 42. The mounting frame 41 extends toward the conveying mechanism 2. An attitude adjustment interval is provided between the mounting frame 41 and the conveying mechanism 2. The plurality of diverter plates 42 are arranged at intervals along a direction perpendicular to the conveying direction of the conveying mechanism 2. The diverter plates 42 and the partition plate 7 are aligned along the conveying direction of the conveying mechanism 2.

[0041] The mounting frame 41 is installed on the front side of the partition plate 7. It can pre-divide the flow through the diverter plate 42, which makes it easier to arrange and adjust the flow through the partition plate 7. Furthermore, by setting a posture adjustment interval between the mounting frame 41 and the conveyor belt 21 of the conveying mechanism 2, the posture adjustment interval can limit the height through which the fish pass. It is preferably limited to the fish in a lying posture, such as 3-6 cm high. When the fish passes through in a back-up posture, it cannot pass through. In this way, the posture of the fish can be pre-diverted and pre-adjusted.

[0042] In one embodiment, the sorting mechanism 5 includes multiple graded conveyor belts 21, a robotic arm 51, a vision acquisition device, and a controller. The graded conveyor belts 21 are arranged side by side along a direction perpendicular to the conveying direction of the conveying mechanism 2. The robotic arm 51 is equipped with a gripper and a vision acquisition device (not shown in the figure) at its execution end. The vision acquisition device and the controller are connected. The controller is used to control the robotic arm 51 to grip the target fish and place it on the corresponding graded conveyor belt 52 according to the image information acquired by the vision acquisition device.

[0043] The robotic arm 51 is equipped with grippers. Since the fish are anesthetized, existing grippers can be used for holding. Considering the potential damage to furniture during gripping, silicone can be used for protection on the inside of the grippers, or an airbag gripper can be used; there are no restrictions. For more accurate gripping, a vision acquisition device is configured, mainly a camera. The controller combines the image information acquired by the camera with the fish morphology data output from each row channel 8 to grade the fish and place them on different grading conveyor belts 52. For example, the morphology data of the fish detected at the current time or within a certain detection time is graded. If the morphology data of the fish in the first row channel 8 is judged to be grade A after grading, the controller controls the robotic arm 51 to move to the exit of that row channel 8 and place the fish gripper on the grading conveyor belt 52 corresponding to the grade A fish. This enables automatic gripping by the robotic arm. It should be noted that this gripping method of the robotic arm 51 is existing technology and does not involve any improvement to the method itself, so it will not be described in detail here.

[0044] In the specific implementation process, a gripping station 22 can also be set at the tail end of the conveyor belt 21 of the conveying mechanism 2 to facilitate the gripping of the robotic arm 51. The partition plate 7 does not extend to this station, so that the robotic arm 51 can easily grip at this station.

[0045] In the specific implementation process, the controller adopts a programmable PLC controller for control, which is connected to the conveying mechanism 2, the graded conveyor belt 52, the metering pump 18, the lateral movement mechanism, the infrared sensor 324, the positioning camera 323, the displacement sensor 322, the robotic arm 51, etc., and performs corresponding control.

[0046] In addition, the conveyor belt 21 of the conveying mechanism 2 is equipped with a mesh structure to facilitate the drainage of accumulated water. A layer of anti-slip silicone can also be applied to the surface of the conveyor belt 21, which can both protect the fish and prevent slipping.

[0047] A method of using a fish morphology data measuring device according to an embodiment of this application: First, water and MS-222 anesthetic are injected into the anesthesia chamber 11 of the anesthesia chamber 1, and the concentration of the anesthetic is controlled at about 150 mg / L. Then, the fish to be measured is put into the fish inlet 13. After the fish is anesthetized, the controller controls the lifting mechanism 16 to lift the filter plate 15 to the second working position. The fish on the filter screen in the second working position are filtered and separated from the water containing the anesthetic. Then, the controller controls the fish pushing mechanism 14 to push the fish from the fish outlet 12 to the conveyor belt 21. The conveyor belt 21 is driven by a stepping movement. During the movement, the messy fish will be initially diverted by the diverting plate 42, and the posture of the fish can also be adjusted by the mounting frame 41. The adjusted fish enter the arrangement channel 8. When the fish passes the detection plate 311, the detection plate 311 will rotate. The angle detection device can collect the rotation angle data of the detection plate 311. The controller calculates the width of the fish based on the rotation angle data. Then, when the fish moves to the lifting mechanism 14, the fish will be measured. When the detection head 32 is below, the positioning camera 323 takes a picture. The controller compares the current image information collected by the positioning camera 323 with the preset reference image to determine whether there is a fish below and whether the fish has moved into position. If no fish is found, the controller will alert the staff. If there is a fish but it has not moved into position, the controller will control the lateral movement mechanism to move and adjust the position of the lifting measuring head according to the comparison. After moving and determining that it has moved into position, the controller will control the lifting detection head 32 to descend to the detection position. During the descent, the measuring plate 321 will retract after contacting the lower part. At this time, the displacement sensor 322 can collect displacement data, and the controller can calculate the thickness of the fish based on this. At the same time, during the contact between the measuring plate 321 and the fish, some infrared sensors 324 will be blocked. The length of the fish can be calculated based on the signal activated by the blocked infrared sensors 324.

[0048] After the fish are measured by the measuring mechanism 3, the controller classifies them according to the obtained fish morphology data. When it is determined that the fish in some of the arrangement channels 8 are larger fish (such as grade A fish), the controller controls the robotic arm 51 to move to the corresponding clamping station 22 in the arrangement channel 8, and transfers the fish to the corresponding grading conveyor belt 21 by clamping, and then transports it to the corresponding recovery box for recovery through the grading conveyor belt 21. Thus, the measurement is completed.

[0049] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
