Description

Technical Field

[0001] This utility model relates to the technical field of marine aquaculture facilities, specifically to a bottom-mounted shellfish aquaculture cage. Background Technology

[0002] Facility-based aquaculture, as a widely used technology and a direction for modern fisheries development, allows for cultivation in large bodies of water, utilizing the natural environment and offering advantages such as reduced human intervention (water changes, feeding) and lower input costs. Compared to bottom seeding, facility-based aquaculture is more convenient for harvesting and does not damage the seabed environment. Facility-based aquaculture will be the main production method for the future healthy development of marine aquaculture and is also a crucial measure in my country's recent efforts to adjust the fisheries structure and accelerate the development of the fisheries industry. Currently, most shellfish aquaculture facilities are floating, which have many shortcomings, such as susceptibility to water temperature, light, and wave disturbances; lack of natural food affecting growth; high consumption of plastic / foam floating materials causing environmental pollution; large amounts of fouling organisms reducing the permeability of the facilities; and increased labor intensity and workload for cleaning. How to improve existing shellfish marine aquaculture models and achieve large-scale, intensive, mechanized, green, and sustainable development urgently needs breakthroughs. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a bottom-mounted shellfish aquaculture cage, enabling intensive seabed shellfish farming. This solves the problem of seabed damage caused by bottom-seeded shellfish trawling harvesting, as well as the problems of scarce natural food, high susceptibility to water temperature, and difficulty in cleaning attached fouling organisms in surface floating aquaculture, thus meeting the requirements of modern green fisheries development.

[0004] The bottom-mounted shellfish aquaculture cage includes a steel cubic frame and several cage units, with several cage units that can be detachably installed at intervals within the cubic frame space.

[0005] The cube frame is assembled from several horizontal hanging beams and crossbeams, and vertical longitudinal beams. The hanging beams and crossbeams are connected in an alternating manner to form the upper and lower planes of the cube frame. The longitudinal beams are connected between the upper and lower planes of the cube frame and extend downward beyond the lower plane. The bottom of the longitudinal beams is connected to an anti-siltation chassis.

[0006] The aforementioned net cage unit is a multi-layer net cage or multi-layer aquaculture net cage, which can be detachably installed between the upper and lower planes of a cubic frame.

[0007] Preferably, the bottom-mounted shellfish aquaculture cage is divided into an aquaculture area and a passageway area, with a passageway area between the aquaculture areas. No cage units are installed in the passageway area, which increases the water permeability of the bottom-mounted shellfish aquaculture cage during seabed aquaculture and facilitates the installation and dismantling of cage units.

[0008] More preferably, the channel area is cross-shaped.

[0009] Preferably, a steel structure lifting beam is installed on the top of the cubic frame to distribute the tension evenly when the bottom-mounted shellfish aquaculture cage is hoisted. The lifting beam is symmetrically equipped with lifting rings to facilitate the connection of the lifting rope, effectively shorten the distance between the lifting points, and avoid the compression and deformation of the bottom-mounted shellfish aquaculture cage due to its large size during hoisting.

[0010] Preferably, the bottom of the longitudinal beam is rotatably connected to an anti-siltation chassis. After the bottom-mounted shellfish aquaculture cage is placed on the seabed, the anti-siltation chassis lies flat against the seabed surface, reducing the local pressure of the bottom-mounted shellfish aquaculture cage on the ground and reducing siltation. When the bottom-mounted shellfish aquaculture cage is lifted by the harvesting crane, the anti-siltation chassis rotates vertically along the longitudinal beam, reducing lifting resistance.

[0011] More preferably, the anti-siltation chassis is provided with a groove structure, the groove width being greater than the width of the crossbeam and the longitudinal beam. When the anti-siltation chassis is flipped in the vertical direction of the longitudinal beam, the groove structure allows the longitudinal beam and the crossbeam to pass through, and the increased flipping angle further reduces the lifting resistance.

[0012] Preferably, the cube frame is provided with several intermediate crossbeams to increase the strength of the cube frame.

[0013] Preferably, the hanging beams and crossbeams are provided with mounting holes or hanging rings at intervals to facilitate the positioning and installation of the cage units.

[0014] Preferably, the cube frame is made of angle steel and / or steel plate and assembled by bolt connection.

[0015] The advantages of this utility model compared with the prior art are:

[0016] 1. The steel cubic frame is a prefabricated structure, and the breeding units can be disassembled and installed. It not only meets the stability requirements of the breeding equipment, but also meets the actual production needs of easy processing, transportation and operation. It is lightweight, easy to handle and put into operation, and can be assembled on the production site, effectively reducing labor and transportation costs.

[0017] 2. Bottom-mounted shellfish farming cages can be flexibly divided into farming and channel zones according to their size. Larger cages can be divided into channel zones to increase water permeability during seabed aquaculture, while also facilitating the installation and dismantling of cage units.

[0018] 3. Bottom-mounted shellfish farming cages form independent farming spaces that can be used individually or in large-scale deployments. They provide ample food for seabed farming and have low management costs from deployment to harvesting. They can be directly harvested by mechanical hoisting, reducing environmental damage and meeting the requirements of green and ecological farming. This creates a new model of intensive and facility-based farming at the bottom of the sea. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the utility model or its application or use.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0029] This invention can be used for seabed aquaculture of shellfish such as oysters, scallops, bay scallops, cockles, and blood clams. In this embodiment, the aquaculture of scallops in the Dalian sea area is used as an example for illustration.

[0030] like Figure 1 and Figure 2 As shown, the bottom-mounted shellfish aquaculture cage includes a steel cubic frame and several cage units 6. Several cage units 6 can be detachably installed at intervals within the cubic frame space. The cage unit 6 is a multi-layer cage or multi-layer aquaculture net cage, which can be detachably installed between the upper and lower planes of the cubic frame.

[0031] like Figure 3 As shown, the bottom-mounted shellfish aquaculture cage is divided into an aquaculture area and a passageway area. The passageway area is set between the aquaculture areas and is shaped like a cross. The cage unit 6 is not installed in the passageway area, which increases the water permeability of the bottom-mounted shellfish aquaculture cage during seabed aquaculture and at the same time provides convenience for the installation and dismantling of the cage unit 6.

[0032] like Figure 4 As shown, the cube frame is assembled from several horizontal hanging beams 1 and crossbeams, and vertical longitudinal beams 5. The hanging beams 1 and upper crossbeams 4 are staggered to form the upper plane of the cube frame. The hanging beams 1 and upper crossbeams 4 are spaced apart with installation holes or hanging rings for the net cage units, facilitating their positioning and installation. The hanging beams 1 and lower crossbeams 8 are staggered to form the lower plane of the cube frame. Several longitudinal beams 5 connect the upper and lower planes of the cube frame and extend downwards beyond the lower plane. The bottom of the longitudinal beams 5 is connected by hinges or latches to achieve a rotating connection to the anti-siltation base 9. Several intermediate crossbeams 7 are provided to increase the cube frame's strength. A steel structure lifting beam 2 is installed at the top of the cube frame to distribute the tension evenly during the hoisting of the bottom-mounted shellfish aquaculture net cage. Symmetrical lifting rings 3 are provided on the lifting beam 2 to facilitate the connection of lifting ropes, effectively shortening the distance between lifting points and preventing the bottom-mounted shellfish aquaculture net cage from being squeezed and deformed during hoisting due to its large size. The cube frame is made of angle steel and / or steel plates and assembled by bolts. The prefabricated structure not only meets the stability requirements of the breeding equipment, but also meets the actual production needs of easy processing, transportation and operation. It is lightweight, easy to handle and put into use, and can be assembled on the production site, effectively reducing labor and transportation costs.

[0033] like Figure 5 As shown, the anti-siltation base 9 lies flat against the seabed after the bottom-mounted shellfish aquaculture cage is placed on the seabed, reducing the local pressure exerted by the cage on the ground and thus reducing siltation. Figure 6 As shown, when the bottom-mounted shellfish aquaculture cage is harvested and lifted, the anti-siltation base 9 rotates vertically along the longitudinal beam 5 to reduce lifting resistance. The anti-siltation base 9 is equipped with a groove structure, the width of which is greater than the width of the lower crossbeam 8 and the longitudinal beam 5. When the anti-siltation base 9 rotates vertically along the longitudinal beam, the groove structure allows the longitudinal beam 5 and the lower crossbeam 8 to pass through, and the increased rotation angle further reduces lifting resistance.

[0034] This utility model of bottom-mounted shellfish aquaculture cages forms an independent aquaculture space, which can be used individually or in large-scale deployment. It provides ample feed for seabed aquaculture, and the management costs from deployment to harvesting are low. It can be directly harvested by mechanical hoisting, reducing environmental damage, meeting the requirements of green and ecological aquaculture, and forming a new model of intensive and facility-based aquaculture at the bottom of the sea.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
