Description

Technical Field

[0001] The invention relates to the field of marine fisheries, and in particular to a fish storage device based on a marine fishing vessel. Background Art

[0002] As is known, marine fishery is one of the important contents of marine industry, including marine aquaculture, marine fishing and other activities, and the fish storage device is a common device set in a marine fishing vessel for storing fish;

[0003] In the existing fish storage devices of marine fishing vessels, a separate storage bin is basically set in the hull, and then the captured fish is directly poured into the storage bin for storage. Due to the special climate environment in the ocean (often strong winds and waves), the hull is often severely bumpy during driving, and the storage bin is generally not full of fish. Therefore, there will be a certain amount of residual space in the storage bin. As a result, when the hull is bumpy during driving, the fish in the storage bin also shakes with the hull. On the one hand, the fish will collide with each other or the bin wall, causing damage to the fish and affecting the quality of the fish. On the other hand, it will also have a certain impact on the center of gravity of the hull. In the long run, the hull will also be damaged to a certain extent. Summary of the invention

[0004] 1) Purpose of the invention

[0005] In view of this, the purpose of the present invention is to propose a fish storage device based on a marine fishing vessel, so that an appropriate amount of space can always be maintained in the storage area for storing the fish. Therefore, when the hull is bumpy during driving, the shaking amplitude of the fish is greatly reduced due to the limited space margin in the storage area. This not only ensures the quality of the fish, but also reduces damage to the hull.

[0020] As a further description of the above technical solution: it also includes a control unit, the control unit is electrically connected to the first drive motor, and controls the moving speed of the warehouse-adjusting movable wall panel by controlling the first drive motor;

[0021] The control unit includes: a data acquisition module, a data analysis module and a control module. The data acquisition module collects information on the stock of fish in the storage area.

The control module controls the moving speed of the warehouse adjustment movable wall panel based on the calculated fish space margin in the storage area.

[0022] As a further description of the above technical solution: the fish catch inventory information in the storage area is collected by a monitoring device;

[0023] The method for calculating the fish space margin in the storage area based on the collected fish inventory information in the storage area is as follows: Y=L×D, where Y is the fish space margin in the storage area, L is the distance between the top of the fish and the top of the storage area, and the distance between the side wall of the storage area and the movable wall panel for adjusting the warehouse;

[0024] The method for the control module to control the moving speed of the warehouse adjustment movable wall panel according to the calculated fish catching space margin of the storage area includes:

[0025] The threshold value of the fish catch space margin in the preset storage area is (Y1, Y2, Y3), where Y1<Y2<Y3;

[0026] If Y≤Y1, a first moving speed command is generated, and the control module controls the moving speed of the warehouse adjustment movable wall panel according to the first moving speed command;

[0027] If Y1<Y<Y2, a second speed command is generated, and the control module controls the speed of the movable wall panel according to the second speed command;

[0028] If Y2≤Y<Y3, a third moving speed command is generated, and the control module controls the moving speed of the warehouse adjustment movable wall panel according to the third moving speed command;

Therefore, when the hull is bumpy during driving, the shaking amplitude of the fish is greatly reduced due to the limited space margin in the storage area, which not only ensures the quality of the fish, but also reduces the damage to the hull.

[0031] The device is equipped with an auxiliary transfer component below a movable warehouse wall panel capable of changing the effective space size of the storage area. The auxiliary transfer component can assist the conveyor belt to efficiently transfer the fish from the pre-storage area to the storage area. In addition, through the structural design of the auxiliary transfer component, during the process of transferring the fish from the pre-storage area to the storage area, the fish in the storage area will not be abnormally squeezed back to the pre-storage area due to the pressure of the fish in the storage area.

DETAILED DESCRIPTION

[0045] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0046] Example 1

[0047] Reference Figure 1-5: The present embodiment provides a technical solution: a fish storage device based on an ocean fishing vessel, comprising a storage bin 1 and a bin-adjusting movable wall panel 3, wherein the storage bin 1 is arranged in the cabin of the fishing vessel for storing fish, a bin entrance 15 is arranged on the top of the storage bin 1, and a circle of enclosure 14 is installed at the edge of the bin entrance 15 on the top of the storage bin 1, so that the fish can enter smoothly when being poured into the bin entrance 15, an exit door 10 is installed on the side of the storage bin 1, and the bin-adjusting movable wall panel 3 is installed in the storage bin 1, and the bin-adjusting movable wall panel 3 divides the interior of the storage bin 1 into two independent areas, wherein the area close to the bin entrance 15 is a pre-storage area, and the other area is a storage area, and the bin-adjusting movable wall panel 3 can be moved in the storage bin 1 to change the effective volume of the storage area, and a conveyor belt 2 is installed in the storage bin 1 below the bin-adjusting movable wall panel 3, and a first drive motor 20 for driving the conveyor belt 2 is installed on one side of the storage bin 1.

[0048] It should be noted that a monitoring device 19 is installed on the side wall of the storage area. The monitoring device 19 adopts an infrared rangefinder, which is used to monitor the distance between the top of the fish in the storage area and the top of the storage area, and the distance between the side wall of the storage area and the warehouse adjustment movable wall panel, so as to control the movement of the warehouse adjustment movable wall panel 3 according to the space margin in the storage area, so that the volume of the storage area can adapt to the amount of fish. In this way, it can be ensured that an appropriate space margin can always be maintained in the storage area. Therefore, when the hull is bumpy during driving, due to the limited space margin in the storage area, the shaking amplitude of the fish is greatly reduced, which not only ensures the quality of the fish, but also reduces the damage to the hull.

[0049] Furthermore, a control box 12 and a refrigerator 16 are installed outside the storage bin 1. The control box 12 is electrically connected to the electrical equipment in the storage bin 1 for controlling the electrical equipment. The refrigerator 16 is used to cool the storage bin 1 and keep the fish fresh.

[0050] Furthermore, a water collecting bin 11 is provided at the lower part of one side of the storage area, and a water leakage port is provided on the bottom plate inside the storage area at the position of the water collecting bin 11, so that the fish caught in the pre-storage area can be transported and accumulated in the storage area through the conveyor belt 2.

[0051] Example 2

[0052] Reference Figure 1-5: This embodiment provides a technical solution: on the basis of Embodiment 1, a fixed plate 18 is installed on one side of the storage bin 1 at the bin entrance 15, at least four suspension rods 31 are installed between the fixed plate 18 and the inner wall of the storage bin 1, and a plurality of sliding sleeves 34 corresponding to the number and position of the suspension rods 31 are embedded and installed on the bin adjusting movable wall panel 3, and the suspension rods 31 are slidably sleeved in the sliding sleeves 34. Such a structural arrangement enables the bin adjusting movable wall panel 3 to be supported and suspended by the suspension rods 31, and the bin adjusting movable wall panel 3 can move along the length direction of the suspension rod 31 under the action of the sliding sleeves 34 and the suspension rods 31, thereby realizing the change of the space size of the storage area.

[0053] Furthermore, a driving screw rod 32 is installed between the fixed plate 18 and the inner wall of the storage bin 1, and a screw nut 33 adapted to and sleeved with the driving screw rod 32 is embedded and installed on the bin adjusting movable wall panel 3. A second driving motor 30 is installed on the outer wall of the storage bin 1, and the output shaft of the second driving motor 30 is connected to one end of the driving screw rod 32. Such a structural arrangement enables the second driving motor 30 to drive the driving screw rod 32 to rotate when it is running. With the cooperation of the screw nut 33, the bin adjusting movable wall panel 3 can move along the length direction of the suspension rod 31, thereby realizing the change of the space size of the coordinated storage area.

[0054] Furthermore, a guide plate 180 is rotatably installed on one side of the fixed plate 18 close to the warehouse entrance 15, and a guide buffer spring 181 is installed at the bottom of the guide plate 180. Such a structural arrangement allows the fish to fall into the storage bin 1 from the warehouse entrance 15, and then fall onto the conveyor belt 2 after being buffered by the guide buffer spring 181. This can reduce the impact of the fish on the conveyor belt 2, reduce the loss of the conveyor belt 2, and at the same time reduce the impact of the fish, thereby ensuring the quality of the fish.

[0055] Furthermore, a baffle 17 is installed at the bottom of the storage bin 1 at the entrance opening 15, and the baffle 17 is fixedly connected to the inner wall of the entrance opening 15 by a baffle spring 170. Such a structural arrangement prevents the entrance door 13 from opening completely vertically when it is pressed open, thereby preventing the fish from falling directly onto the conveyor belt 2 at the bottom and causing an impact, and at the same time preventing the entrance door 13 from hitting the inner wall of the storage bin 1, thereby protecting the entrance door 13.

[0056] Example 3

[0057] Reference Figure 6-11: This embodiment provides a technical solution: on the basis of embodiment 1, a guide port 36 is provided at the bottom of the warehouse adjusting movable wall panel 3, and an auxiliary transfer component 4 is installed in the guide port 36, which is used to assist the conveyor belt 2 to transfer the fish in the pre-storage area to the storage area for stacking. The auxiliary transfer component 4 includes a rotating frame 43 and a flap 40, wherein the rotating frame 43 is rotatably installed in the guide port 36 along the length direction through a rotating shaft, and a plurality of flaps 40 are provided, which are distributed on the surface of the rotating frame 43 in a circular array and welded along the length direction of the rotating frame 43. Such a structural arrangement enables the flap 40 to rotate along with the rotating frame 43, and the fish is assisted to be transferred to the storage area for stacking through the rotation of the flap 40. In this way, it can avoid excessive accumulation of fish in the storage area, causing it to slide back from the conveyor belt 2 to the pre-storage area, thereby ensuring the fish transfer effect.

[0058] Furthermore, an installation cavity 37 is opened at one end of the warehouse adjusting movable wall panel 3, and a driving pulley 53 and a motor for driving the driving pulley 53 to rotate are rotatably installed in the installation cavity 37. A driven pulley 51 is installed at one end of the rotating shaft of the rotating frame 43, and the driving pulley 53 and the driven pulley 51 are connected by a transmission belt 52. Such a structural arrangement enables the rotating frame 43 to rotate synchronously under the drive of the transmission belt 52 when the motor is running, so that the flap 40 follows the rotation, and the fish is assisted to be transferred to the storage area for stacking through the rotation of the flap 40.

[0059] Furthermore, a rubber strip 400 is installed along the length direction of the edge of the flap 40, which can reduce the damage to the fish when transferring the fish.

[0060] Furthermore, arc-shaped cover plates 35 are symmetrically installed on both sides of the warehouse-adjusting movable wall panel 3. The arc-shaped cover plates 35 are installed along the length direction of the warehouse-adjusting movable wall panel 3. When the rotating frame 43 rotates, the flap 40 can be completely accommodated in the arc-shaped cover plates 35. Such a structural setting can reduce the squeezing effect of fish accumulation in the storage area on the flap 40, thereby ensuring the service life of the flap 40 and the rotating frame 43.

[0061] Furthermore, a pushing assembly 41 is provided between two adjacent flaps 40. The pushing assembly 41 is used to push the fish out of the flip radius area of ​​the flap 40 when the flap 40 transfers the fish from the pre-storage area to the storage area, thereby preventing the fish from being flipped back to the pre-storage area by the flap 40 from above the guide port 36, thereby ensuring the efficiency of fish transfer. The pushing assembly 41 includes a main board 410 and an electric push rod 42, wherein the main board 410 is provided between two adjacent flaps 40, the electric push rod 42 is fixedly mounted on the rotating frame 43, and the piston rod of the electric push rod 42 is connected to one side of the main board 410. Such a structural arrangement enables the electric push rod 42 to push the main board 410 outward when the two adjacent flaps 40 transfer the fish to the storage area, and push the fish between the two adjacent flaps 40 out between the two flaps 40. When the two adjacent flaps 40 rotate to the pre-storage area, the electric push rod 42 contracts to drive the main board 410 to move inward, so that the flap 40 can continuously transfer the fish.

[0062] It should be noted that the function of the arc-shaped cover plate 35 also includes providing a recovery space for the main board 410 when the flap 40 rotates continuously, that is, when the fish between two adjacent flaps 40 is pushed out of the radius area of ​​the flap 40 by the main board 410, when the area between the flaps 40 where the fish is pushed out is completely rotated into the area of ​​the arc-shaped cover plate 35, the main board 410 is recovered. This can prevent the fish in the storage area from being squeezed between the flaps 40 and then being brought back to the pre-storage area during the recovery process of the main board 410, thereby ensuring the fish transfer effect.

[0063] Furthermore, the interior of the main board 410 is hollowed out, and two symmetrical first movable plates 411 are slidably installed inside the main board 410. A second movable plate 412 is movably installed inside the first movable plate 411, and a clamping strip 4120 is provided on the edge of the second movable plate 412, so that the edge of the second movable plate 412 forms a T-shaped clamping structure, and both side surfaces of the flap 40 are provided with a clamping groove 401, and the T-shaped structure on the edge of the second movable plate 412 is slidably engaged in the clamping groove 401. Such a structural arrangement enables the first movable plate 411 and the second movable plate 412 to cooperate with the main board 410 to completely push out the fish between the two adjacent flaps 40 when the electric push rod 42 is pushing the fish, so as to prevent the fish from entering the inner side of the main board 410 and affecting the recovery of the main board 410 and the transfer of the fish.

[0064] Example 4

[0065] This embodiment provides a technical solution: it also includes a control unit, the control unit is electrically connected to the first drive motor 20, and controls the moving speed of the warehouse-adjusting movable wall panel 3 by controlling the first drive motor 20;

[0066] The control unit includes: a data acquisition module, a data analysis module and a control module. The data acquisition module collects information on the stock of fish in the storage area. The data analysis module calculates the fish space margin in the storage area based on the collected information on the stock of fish in the storage area. The control module controls the moving speed of the warehouse adjustment movable wall panel 3 based on the calculated fish space margin in the storage area.

[0067] As a further description of the above technical solution: the fish catch inventory information in the storage area is collected by the monitoring device 19;

[0068] The method for calculating the fish space margin in the storage area according to the collected fish inventory information in the storage area is as follows: Y=L×D, wherein Y is the fish space margin in the storage area, L is the distance between the top of the fish and the top of the storage area, and the distance between the side wall of the storage area and the movable wall panel 3 for adjusting the warehouse;

[0069] The method for the control module to control the moving speed of the warehouse adjustment movable wall panel 3 according to the calculated fish catching space margin in the storage area includes:

[0070] The threshold value of the fish catch space margin in the preset storage area is (Y1, Y2, Y3), where Y1<Y2<Y3;

[0071] If Y≤Y1, a first moving speed command is generated, and the control module controls the moving speed of the warehouse adjustment movable wall panel 3 according to the first moving speed command;

[0072] If Y1<Y<Y2, a second speed command is generated, and the control module controls the speed of the warehouse adjustment movable wall panel 3 according to the second speed command;

[0073] If Y2≤Y<Y3, a third moving speed command is generated, and the control module controls the moving speed of the warehouse adjustment movable wall panel 3 according to the third moving speed command;

[0074] If Y≥Y3, a stop command is generated, and the control module controls the warehouse-adjusting movable wall panel 3 to stop moving, wherein the third moving speed command, the second moving speed command, and the first moving speed command control the moving speed of the warehouse-adjusting movable wall panel 3 to increase in sequence;

[0075] It should be noted that the fish space margin is the basis for judging the proportion of fish space in the storage area. The larger the fish space margin is, the slower the moving speed of the warehouse adjusting movable wall panel 3 is. Conversely, the smaller the fish space margin is, the faster the moving speed of the warehouse adjusting movable wall panel 3 is. This can ensure that when the fish is transferred, the storage area can avoid being completely squeezed and filled. In addition, the moving speed control of the warehouse adjusting movable wall panel 3 is carried out when the storage bin 1 is loading goods. When the loading is completed and the fish space margin in the pre-storage area is zero (it can be monitored by installing a camera in the pre-storage area), the control unit controls the moving direction of the warehouse adjusting movable wall panel 3 according to the current fish space margin in the storage area until the fish space margin in the storage area reaches a predetermined value. In this way, when the hull is bumpy during driving, the shaking amplitude of the fish is greatly reduced due to the limited space margin in the storage area.

[0076] The exemplary implementation scheme of the present disclosure is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
