[0028] The utility model provides a fish collecting and catching device.

[0029] Reference Figures 1 to 4 In one embodiment of the utility model, the fish collecting device comprises a net frame structure 1 and a fish suction mechanism 2. The periphery of the net frame structure 1 is used to contact the inner wall of the fish storage box 3; the net frame structure 1 comprises a frame structure 11 and a fishing net 12, and the outer surface of the frame structure 11 is covered with the fishing net 12; the interior of the frame structure 11 is provided with a cavity, and the cavity is used to store gas; the fish suction mechanism 2 comprises a fish suction pump 21 and a fish suction pipe 22, the fish suction pump 21 is provided on one side of the frame structure 11, one end of the fish suction pipe 22 is connected to the fish suction pump 21, and the other end of the fish suction pipe 22 is used to connect to the external space.

[0030] By using the frame structure 11 as the supporting structure of the fishing net 12, a cavity is provided inside the frame structure 11, and the cavity is used to store gas. The gas is used to provide buoyancy for the net frame structure 1 in the water body, so that the fish collecting device overcomes its own gravity and floats on the water surface; the fish suction pump 21 is arranged at the bottom of the frame structure 11, and the fish suction pump 21 needs to be started when the fish collecting device is operating to catch fish. The fish suction pump 21 will generate downward pressure in the process of sucking fish. The downward pressure provided by the fish suction pump 21 plus the gravity of the net frame structure 1 is greater than the buoyancy of the net frame structure 1, and the net frame structure 1 will slowly move downward, and the activity space of the farmed fish in the fish storage box 3 will be gradually compressed, so as to achieve the purpose of gathering fish downward; and the concentrated fish will be sucked up by the fish suction pump 21 and directly discharged from the fish suction pipe 22 to the external space to complete the fishing operation; when the fishing operation is completed, the fish suction pump 21 stops working, and the net frame structure 1 will automatically float to the water surface under the action of buoyancy. The net frame structure 1 cooperates with the fish suction mechanism 2 to achieve the purpose of quickly catching fish. The fish collecting and capturing device has the advantages of high fishing efficiency, high operation safety, low operation labor intensity, and low requirements for sea conditions and environment; and the overall structure of the fish collecting and capturing device is simple and requires less power source, which not only saves energy loss but also reduces production costs.

[0031] By setting a cavity for storing gas in the frame structure 11, the gas is used to provide buoyancy for the fish collecting device, so that the fish collecting device floats on the water surface in a natural state, and can automatically float back to the water surface after sinking, without the need to set up a power device to reset the fish collecting device after operation. At the same time, the fish suction pump 21 has a strong suction force, which can quickly suck fish out of the water, improve the efficiency of catching fish, and provide downward pressure for the fish collecting device. The downward pressure is greater than the buoyancy of the fish collecting device, so the fish collecting device will slowly descend, and there is no need to set up a special power device; only the fish suction pump 21 needs to be used as a power device to provide the fish collecting device with suction force and downward pressure for sucking fish.

[0032] Optionally, the fish collecting and catching device further comprises a fish storage box 3 , the outer peripheral shape of the frame structure 11 is adapted to the inner shape of the fish storage box 3 , and the frame structure 11 can move up and down in the fish storage box 3 .

[0033] The fish storage box 3 includes a breeding box or a box body of a breeding ship or a box of a live fish transport ship. The fish storage box 3 is completely covered by the net frame structure 1, so that the outer periphery of the net frame structure 1 is in better contact with the inner wall of the fish storage box 3; at the same time, the net frame structure 1 can move up and down along the inner wall of the fish storage box 3 to prevent fish from slipping away from the gap between the net frame structure 1 and the inner wall of the fish storage box 3, thereby improving the fish gathering effect of the fish gathering device.

[0034] Optionally, a brush structure is arranged around the outer circumference of the outer frame. The fish storage box 3 is made of a steel net box. Since the fishing net 12 is a flexible net structure, there will be a gap between the inner wall of the fish storage box 3 and the net frame structure 1. The brush structure is arranged around the outer circumference of the outer frame 111 to fill the gap, thereby preventing fish from slipping away from the gap between the net frame structure 1 and the inner wall of the fish storage box 3, and further improving the fish gathering effect of the fish gathering device.

[0035] Optionally, the fish collecting device further comprises a guide mechanism 4 , which is extended along the height direction of the fish storage box 3 ; the net frame structure 1 slides along the guide mechanism 4 .

[0036] The guide mechanism 4 is extended along the height direction of the fish storage box 3. When the net frame structure 1 moves up and down, the frame structure 11 can slide along the guide mechanism 4. The guide mechanism 4 plays a guiding role and will not affect the movement of the frame structure 11. Adding the guide mechanism 4 can increase the stability of the operation of the fish collecting and capturing device, and provide a certain limiting effect for the frame structure 11 to avoid the frame structure 11 from tilting.

[0037] Optionally, the guide mechanism 4 includes a guide rail 41, a guide wheel 42 and a locking device (not shown in the figure), the guide rail 41 extends along the height direction of the fish storage box 3, the guide wheel 42 is fixedly connected to one side of the frame structure 11, the guide wheel 42 can roll up and down along the guide rail 41, and the locking device is used to limit the movement of the frame structure along the guide rail 41.

[0038] The guide wheel 42 is arranged on one side of the outer periphery of the frame structure 11 and connected. When the frame structure 11 moves up and down, the guide wheel 42 rolls along the guide rail 41. The guide wheel 42 supports and guides the frame structure 11 to perform linear reciprocating motion along a given trajectory and stroke. The addition of the guide wheel 42 can reduce the friction between the frame structure 11 and the inner wall of the fish storage box 3. The locking device is connected to the frame structure 11. The locking device includes a driving member and a friction block. When the guide wheel needs to be locked, the driving member is used to push the friction block against the guide rail 41, thereby increasing the friction between the friction block and the guide rail 41, so that the friction block and the guide rail 41 cannot move relative to each other, and the guide wheel 42 cannot roll along the guide rail 41; and the friction block is connected to the frame structure 11, so the locking device can limit the movement of the frame structure 11 along the guide rail 41, and finally achieve the purpose of locking the frame structure 11. The driving member can be a hydraulic telescopic rod or an electromagnetic telescopic rod.

[0039] Optionally, the frame structure 11 includes an outer frame 111, an inner frame 112 and a plurality of connecting rods 113, the outer frame 111 and the inner frame 112 are connected by the connecting rods 113; the fish suction mechanism 2 is connected to the inner frame 112; the outer frame 111, the inner frame 112 and the connecting rods 113 are all connected to one side of the fishing net 12, and the outer frame 111, the inner frame 112 and the connecting rods 113 provide support for the fishing net 12.

[0040] The inner frame 112 is arranged in the middle of the outer frame 111, and the two ends of the connecting rod 113 are respectively connected to the outer frame 111 and the inner frame 112, and the connecting rod 113 is evenly arranged between the inner frame 112 and the outer frame 111, so as to improve the support of the frame structure 11; in addition, the fish suction pump 21 is fixed on the inner frame 112 and connected, and one end of the fish suction tube 22 is fixedly connected to the inner frame 112, and the fish suction pump 21 is connected to this end of the fish suction tube 22 at the same time. During the descent of the frame structure 11, the activity space of the fish is continuously compressed until the fish gather at the bottom of the frame structure 11, and the fish suction pump 21 provides a strong suction force to suck out the fish, thereby improving the fishing efficiency.

[0041] Optionally, the fish suction pumps 21 are all connected to one end of the fish suction pipe 22 , and a plurality of fish suction pumps 21 are arranged around the inner frame 112 ; a plurality of fish suction pumps 21 are arranged at intervals; a plurality of fish suction pumps 21 are all connected to one end of the fish suction pipe 22 .

[0042] In order to arrange at least three fish suction pumps 21 on the inner frame 112, the three fish suction pumps 21 are arranged at intervals, and several fish suction pumps 21 are connected to one end of the fish suction pipe 22. When the three fish suction pumps 21 work at the same time, the working efficiency is three times the original, and the drop pressure is also three times the original, further improving the fishing efficiency and fishing speed of the fish gathering and catching device.

[0043] Optionally, the fish suction pump 21 includes a shaftless rim fish suction pump 21. Currently, the commonly used shaftless rim fish suction pumps 21 can be mainly divided into centrifugal, jet and vacuum types. The centrifugal fish suction pump 21 has high efficiency, but its impeller causes great damage to the fish body. Therefore, a jet type or vacuum type shaftless rim fish suction pump 21 can be used, which causes less damage to the fish body and improves the fishing quality of the fish collection and catching device.

[0044] Optionally, the width of the inner frame 112 is smaller than that of the outer frame 111, the inner frame 112 is located above the outer frame 111, the upper end of the connecting rod 113 is connected to the inner frame 112, the lower end of the connecting rod 113 is connected to the outer frame 111, and the lower end of the connecting rod 113 is inclined outward.

[0045] The inner frame 12 is a circular frame, and the outer frame 111 is a hexagonal frame, which includes at least six connecting rods 113. When the inner frame 112 and the outer frame 111 are connected by the connecting rods 113, one end of the connecting rod 113 is connected to the corner of the outer frame 111, which can improve the stability of the frame structure 11. The lower end of the connecting rod 113 is inclined outward, and the part of the fishing net 12 supported by the connecting rod 113 is in an inclined state; during the descent of the frame structure 11, the inclined fishing net can gather fish to the middle of the net frame structure 11, making it easier for the fish suction pump 21 to suck fish, thereby improving the fish suction efficiency of the fish suction pump 21.

[0046] Optionally, the outer frame 111 , the inner frame 112 and the connecting rod 113 are all made of hollow tubes, and a cavity is formed inside the hollow tubes.

[0047] Hollow pipes are conventional supporting materials and do not require special production, which reduces the difficulty of producing the fish collecting and catching device; the outer frame 111, the inner frame 112 and the connecting rod 113 are all made of hollow pipes, which can reduce the dead weight of the net frame structure 1 and the force required for the net frame structure 1 to float, so that the fish suction pump 21 provides a downward pressure on the net frame structure 1, and the pressure is large enough to make the net frame structure 1 descend in the fish storage box 3, so that the net frame structure 1 cooperates with the fish suction mechanism 2 to achieve the purpose of automatic lifting, automatic fish gathering, and rapid fishing.

[0048] In another embodiment, by making the self-gravity of the fish collecting and capturing device greater than that on the water surface, the self-weight of the frame structure is less than the buoyancy, and the fish suction pump 21 is arranged on the top of the frame structure 11, and the frame structure 11 is arranged below the fish; when the fish collecting and capturing device is operating to catch fish, the fish suction pump 21 needs to be started, and the fish suction pump 21 will generate upward pressure in the process of sucking fish. The upward pressure provided by the fish suction pump 21 plus the buoyancy of the net frame structure 1 is greater than the self-gravity of the net frame structure 1, and the net frame structure 1 will slowly move upward, and the activity space of the fish in the fish storage box 3 will be gradually compressed, thereby achieving the purpose of gathering fish upward.

[0049] The technical solution of the utility model adopts a frame structure 11 as a supporting structure of a fishing net 12. A cavity is provided inside the frame structure 11. The cavity is used to store gas. The gas is used to provide buoyancy for the net frame structure 1 in the water body, so that the fish collecting device overcomes its own gravity and floats on the water surface. When the fish collecting device is engaged in fishing operations, it is necessary to start a fish suction pump 21. The fish suction pump 21 will generate downward pressure during the process of sucking fish. The downward pressure provided by the fish suction pump 21 plus the gravity of the net frame structure 1 is greater than the buoyancy of the net frame structure 1. The net frame structure 1 will slowly move downward, and the activity space of the farmed fish in the fish storage box 3 will be gradually compressed, thereby achieving the purpose of gathering fish. The gathered fish will be sucked up by the fish suction pump 21 and directly discharged from the fish suction pipe 22 to the external space, completing the fishing operation. When the fishing operation is completed, the fish suction pump 21 stops working, and the net frame structure 1 will automatically float to the water surface under the action of buoyancy. The net frame structure 1 cooperates with the fish suction mechanism 2 to achieve the purpose of quickly catching fish. The fish collecting and capturing device has the advantages of high fishing efficiency, high operation safety, low operation labor intensity, and low requirements for sea conditions and environment; and the overall structure of the fish collecting and capturing device is simple and requires less power source, which not only saves energy loss but also reduces production costs.
