Description

Technical Field

[0001] This invention relates to the field of aquaculture equipment, and in particular to a nearshore shellfish aquaculture system. Background Technology

[0002] Existing nearshore shellfish aquaculture systems primarily utilize cages, which are typically cylindrical with convection holes on their surfaces. Shellfish are placed inside these cages, which are then secured to nearshore posts with ropes. Because the convection holes in these cages are relatively uniform in size, the cages need to be replaced with larger-diameter cages after the shellfish reach a certain growth stage, increasing the workload for farmers. Furthermore, the inability to adjust the cage height means that during high tide, the cages are completely submerged, resulting in limited sunlight access for the shellfish at this stage. Summary of the Invention

[0003] This invention relates to a nearshore shellfish aquaculture system, which has the following objectives:

[0004] Objective 1: To provide a breeding cage that is easy to store and easy to raise, and the convection hole diameter of the breeding box is adjustable to ensure that the shellfish do not need to be replaced throughout the growth cycle, thus reducing the workload of farmers.

[0005] Objective 2: To make it easier to adjust the height of the breeding box, further reducing the workload of farmers.

[0006] This invention is achieved through the following technical solution: a nearshore shellfish aquaculture system, which includes...

[0007] Several columns are arranged in a rectangular array in the near-shore area;

[0008] Hook mechanism 2 is connected to column 1;

[0009] The suspension rope 3 is connected to the hook mechanism 2;

[0010] The breeding box 4 has a hollow box body with a connecting hook 40 on the top; the connecting hook 40 is hung on the hanging rope 3;

[0011] The breeding box 4 is a horizontal long cylindrical box, which includes a bottom plate 41, a top plate 42, a V-shaped side plate 43, a rear side plate 44, and a door panel 45. The bottom plate 41, the top plate 42, and the V-shaped side plate 43 enclose a cylindrical body with a hexagonal cross section. The rear side plate 44 blocks the rear side of the cylindrical body. The lower edge of the door panel 45 is hinged to the lower edge of the front side of the cylindrical body. The upper edge of the door panel 45 and the front edge of the cylindrical body are provided with fasteners 451 that cooperate with each other.

[0012] The inner side of the cylinder is provided with several reinforcing strips 46; the surface of the cylinder is provided with several convection holes of the same specification 47.

[0013] Compared with the prior art, the present application has the following advantages:

[0014] 1. The cross section of the culture box is hexagonal, which is easy to arrange and store, and the flat bottom is beneficial to the uniform distribution of shellfish and improves the quality of shellfish;

[0015] 2. The aperture of the convection hole of one culture box can be adjusted, which ensures that the shellfish does not need to be replaced in the entire growth cycle, and reduces the workload of the aquaculture farmers;

[0016] 3. The special hook mechanism can ensure that the suspension rope and the hook are tightly connected, and prevent the suspension rope from slipping on the hook mechanism after suspending the culture box.

DETAILED DESCRIPTION

[0032] The invention will be described in detail below in conjunction with the accompanying drawings:

[0033] As shown in Figures 1-3 , Figure 11 : the shellfish offshore aquaculture system, which comprises

[0034] column 1, provided with several, according to the rectangular array inserted in the offshore area;

[0035] hook mechanism 2, connected with the column 1;

[0036] suspension rope 3, connected to the hook mechanism 2;

[0037] breeding box 4, with the connecting hook 40 of the hollow box body on the top; connecting hook 40 is hung on the suspension rope 3;

[0038] Among them, the breeding box 4 is a horizontal long cylinder type box body, the box body includes bottom plate 41, top plate 42, V-shaped side plate 43, rear side plate 44 and door plate 45, the bottom plate 41, the top plate 42 and the V-shaped side plate 43 are enclosed to form a cylinder with a hexagonal cross section, the rear side plate 44 blocks the rear side of the cylinder, the lower edge of the door plate 45 is hinged to the front side lower edge of the cylinder, and the upper edge of the door plate 45 and the front side edge of the cylinder are provided with fasteners 451 matched with each other;

[0039] The inner side of the cylinder is provided with a plurality of reinforcing strips 46; the surface of the cylinder is provided with a plurality of convection holes 47 of the same specification.

[0040] The column 1 is not different from the existing breeding cage fixed column structure; generally, it is a wooden column, which is mainly inserted into the seabed, and the suspension rope is provided between the columns.

[0041] The hook mechanism 2 is fixed on the column for the fixation of the suspension rope.

[0042] The breeding box of this invention differs from traditional breeding cages; its cross-section is hexagonal, making it easy to organize and store. Figure 13 As shown, most aquaculture tanks are placed vertically; the flat bottom facilitates the even distribution of shellfish, improving their quality. The inner side of the tank has several reinforcing strips 46, which enhance the overall strength of the tank. The surface of the tank has several identical convection holes 47, enabling material exchange between the tank and the outside environment, ensuring that organic matter from the seawater enters the tank and provides food for the shellfish.

[0043] The rear side panel 44 and door panel 45 can also be provided with convection holes 47, but since the rear side panel 44 and door panel 45 do not have a hole diameter adjustment structure, the convection holes 47 of the rear side panel 44 and door panel 45 are generally designed according to the minimum size.

[0044] like Figures 4-8 As shown: The front and rear sides of the cylinder are provided with limiting plates 48 extending outward; an outer sliding cylinder 5 with a diameter larger than that of the cylinder is sleeved around the cylinder, the length of the outer sliding cylinder 5 is shorter than that of the cylinder, and the outer sliding cylinder 5 is provided with auxiliary convection holes 51 that correspond one-to-one with the convection holes 47 of the cylinder.

[0045] A number of front-to-back extending limiting holes 491 are provided on the outer surface of the top plate 42, and some of the limiting holes 491 are provided with limiting pins 492.

[0046] By sliding the outer sliding cylinder 5, the convection hole 47 and the secondary convection hole 51 can be made to overlap or intersect, thereby adjusting the actual size of the openings between the breeding box and the outside. When the outer sliding cylinder 5 is slid into place, the outer sliding cylinder 5 is limited by inserting limit pins 492 into the limit holes 491 at both ends of the outer sliding cylinder 5.

[0047] The upper surface of the top plate 42 is provided with several semi-circular protrusions 493. This can reduce the contact area between the outer sliding cylinder and the top plate 42, thereby reducing the friction force of the outer sliding cylinder sliding on the cylinder and making its sliding smoother.

[0048] Both the convection hole 47 and the secondary convection hole 51 are square openings with a side length of 20±0.5mm, and the distance between any two adjacent square openings is 10±0.5mm; the angle between the side of the square opening and the edge of the breeding box 4 is 45°.

[0049] Depending on the degree of overlap of the square openings, the maximum opening size can be controlled to be a square opening with a side length of 20mm, and the minimum opening size to be a square opening with a side length of 5mm. (Reference) Figures 6-8 ;in Figures 6-8 The arrow in the image represents a hole that is the same as the outside.

[0050] The connecting hook 40 is provided with two grooves 401, one of which extends in the front-back direction, and the other extends in the left-right direction. The arrangement of the culture box can be controlled according to the wind direction.

[0051] As shown in Figure 11 The hook mechanism 2 comprises a fixed seat 21 and a hook 22 arranged on the surface of the fixed seat 21. The fixed seat 21 is provided with a screw hole. The lower end of the hook 22 is connected with the fixed seat 21. The lower part of the hook 22 is arc-shaped and the lower end is connected with the fixed seat. The part of the fixed seat 21 corresponding to the lower part of the hook 22 is provided with an arc-shaped notch. The middle part of the hook 22 is provided with a recess 221 extending towards the fixed seat 21. The upper end of the hook 22 is inclined away from the fixed seat 21. A sharp 222 extending downward is arranged below the recess 221.

[0052] The suspension rope is embedded in the hook 22, and the hook is tightened inward to clamp the suspension rope. Since the recess is provided with a sharp, the suspension rope and the hook can be tightly connected to prevent the suspension rope from slipping on the hook. If necessary, a rubber sleeve can be provided on the suspension rope to further increase the friction between the suspension rope and the hook.

[0053] A reinforcing plate 23 is arranged between the lower part of the hook 22 and the fixed seat 21. The reset ability and strength of the hook are increased to prevent the hook from breaking.

[0054] As shown in Figures 9-10 It further comprises a lifting mechanism. The lifting mechanism comprises

[0055] A support base 61 is fixedly arranged at the upper end of the column 1. An upper bearing limiting groove 611 is arranged on the support base 61.

[0056] A thrust ball bearing 62 is embedded in the bearing limiting groove 611 and fixedly connected with the bottom cover of the bearing limiting groove 611.

[0057] A screw rod 63 is connected with the top cover of the thrust ball bearing 62 to realize rotation relative to the support base 61.

[0058] A column outer sleeve 64 is open at the bottom and provided with an inner thread at the center of the top cover for cooperation with the screw rod 63. The hook mechanism 2 is connected with the column outer sleeve 64.

[0059] A vertical guide groove 11 is arranged on the outer side of the column 1. A guide block 641 is embedded in the guide groove 11 on the inner wall of the column outer sleeve 64.

[0060] When in use, the screw 63 is manually rotated, and since the outer sleeve 64 of the stand is connected with the screw 63 in a threaded manner, the outer sleeve 64 of the stand will be raised or lowered when the screw 63 is rotated, and since the hook mechanism 2 is connected with the outer sleeve 64 of the stand, the hook mechanism will be raised or lowered together with the suspension rope and the breeding box.

[0061] It also comprises a stand reinforcing sleeve 7 which is made of metal material and sleeved on the upper end of the stand 1, and a sub-guide groove 71 corresponding to the guide groove 11 is arranged on the surface of the stand reinforcing sleeve 7.

[0062] Since the stand is mostly made of wood, in order to increase the strength of the upper end, the upper part of the stand is coated, that is, the stand reinforcing sleeve 7 is added, so that the metal coating layer is added to the surface of the stand.

[0063] Although the present application is illustrated and described with reference to specific embodiments and alternatives thereof, it is understood that various changes and modifications can be made without departing from the spirit and scope of the present application. Therefore, it is understood that the present application is not limited to the specific embodiments described above except as defined in the appended claims and their equivalents.
