Description

Technical Field

[0001] The invention relates to the field of aquaculture equipment, and in particular to an assembled aquaculture cage and a use method thereof. Background Art

[0002] Cage culture is a new technology for the development of intensive production in the aquaculture industry in the world today. Cages are made of synthetic fiber mesh or metal mesh, assembled into boxes of certain shapes and specifications, and aquatic organisms to be cultured are placed in the boxes, and then placed in water bodies suitable for culture. It is a highly intensive culture method that applies the water body intensive culture technology to larger water surfaces with superior environmental conditions to achieve high yields. It has the advantages of short breeding cycle, convenient management, flexibility, and simple operation.

[0003] In the prior art, the cages used usually use metal structures such as welding or bolts to connect and fix the frame to the mesh body. However, when aquaculture is carried out in seawater, the corrosion of the welding points, bolts and metal structures by seawater easily causes the welding points and metal structures to rust. Under the impact of the undercurrent of the water body, the rusted welding points or bolts are prone to breakage, resulting in the disintegration of the cage and the escape of the aquatic creatures. In addition, in order to facilitate the installation and maintenance of the cage, a filter-type sleeve cage for freshwater aquaculture disclosed in publication number CN113439701B uses a connection method between the mesh plate and the frame through a slide groove or a slot. However, this connection method easily causes pollutants such as silt in the water body or excrement of aquatic creatures to accumulate in the slot, making it inconvenient to clean the pollutants from the slot. The pollutants accumulated in the slot for a long time are prone to accelerate the corrosion of the cage structure, reducing the service life of the cage, and the cleaning of the slot requires a lot of time and energy, thereby reducing the utilization efficiency of the cage and increasing the cost of aquatic cage farming. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides an assembled aquaculture cage and a method of use which are convenient for installation, cleaning and maintenance.

[0005] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is:

[0006] Provided is an assembled aquaculture cage, comprising a bottom frame and a top frame, wherein the bottom frame and the top frame are connected by four columns to form a frame structure, and side nets are arranged on the four sides of the frame structure; and a bottom net is arranged on the bottom surface of the frame structure;

[0007] Two first slide grooves that slide with the bottom net are symmetrically arranged on the inner side of the bottom frame, and the frame structure, the bottom net and the side nets are combined and connected to form a net box;

[0008] One side of the bottom frame is provided with a first opening for the bottom net to slide into the first chute; a first airbag limiting component for fixing the bottom net is arranged at the first opening;

[0009] The top frame is provided with four second openings for cooperating with and connecting the four side nets, and second airbag limiting components for fixing the side nets are arranged at the four second openings; a first ventilation pipe is arranged inside the side wall of the top frame, and the second airbag limiting component is connected to the first ventilation pipe; a first air hole communicating with the first ventilation pipe is arranged on the side wall of the top frame, and a valve core is arranged at the first air hole;

[0010] The bottom frame is provided with a card slot for cooperating with and connecting the four side nets; and a first airbag slag removal component is arranged at the bottom of the card slot.

[0011] Furthermore, the bottom net includes a bottom net frame and a net surface, and the first airbag limiting component includes a first opening arranged on the side wall of the first opening and a first limiting hole arranged on the bottom net frame;

[0012] A vertical first airbag column is arranged at the first opening. The first airbag column is located inside the first opening in the non-inflated state; when the bottom net is in sliding fit with the first chute, the first airbag column is inflated so that the first airbag column protrudes from the side wall of the first opening, and the first airbag column is in fit connection with the first limiting hole;

[0013] A second air hole communicating with the first airbag column is further arranged on the side wall of the bottom frame, and the second air hole is located on the side wall of the bottom frame at the first opening; a valve core is arranged at the second air hole.

[0014] Furthermore, third airbag limiting components are arranged at the bottoms of the two first chutes that are in sliding fit with the bottom net;

[0015] The third airbag limiting component includes a first airbag strip arranged on the bottom of the first chute and a third limiting hole arranged on the bottom net frame; a third airbag column is arranged on the first airbag strip, and a third opening for accommodating the third airbag column is further arranged on the bottom of the first chute; the third airbag column is located inside the third opening in the non-inflated state, and the first airbag strip is attached to the wall of the first chute; when the bottom net is in fit connection with the first chute, the first airbag strip is inflated so that the third airbag column protrudes from the first airbag strip and is in fit connection with the third limiting hole, and the first airbag strip abuts against the bottom net frame; when the bottom net is not in fit connection with the first chute, the first airbag strip protrudes from the first chute in the inflated state;

[0016] A second ventilation pipe is arranged inside the side wall of the bottom frame, and the first airbag strip and the second air hole are both communicated with the second ventilation pipe.

[0017] Furthermore, the side net includes a side net frame and a net surface, and the second airbag limiting component includes a second opening arranged on the side wall of the top frame and a second limiting hole arranged on the side net frame;

[0018] A second air bag column communicating with the first ventilation pipe is arranged at the second opening, and the second air bag column is located within the second opening in the non-inflated state; when the side net is connected to the card slot in a matching manner, the second air bag column is inflated so that the second air bag column protrudes from the second opening, and the second limiting hole of the second air bag column is connected in a matching manner.

[0019] Further, the first air bag column, the second air bag column or the third air bag column includes a cylindrical column body, and a number of elastic threads are arranged inside the column body. One ends of the number of elastic threads are fixedly connected to the center of the top end of the column body, and the other ends of the number of elastic threads are fixedly connected to the top frame or the bottom frame, and the other ends of the number of elastic threads are distributed circumferentially along the axis of the column body; when the first air bag column, the second air bag column or the third air bag column is in the non-inflated state, the elastic threads pull the first air bag column, the second air bag column and the third air bag column into the first opening, the second opening and the third opening respectively.

[0020] The arrangement of the elastic threads can accelerate the discharge of air in the first air bag column and the second air bag column when the fish cage is disassembled and repaired, so that the first air bag column and the second air bag column can quickly return to the initial state, avoiding irreversible damage caused by the column body not withdrawing from the first limiting hole, the second limiting hole or the third limiting hole when the side net or the bottom net is pulled out.

[0021] Further, the first air bag slag removal assembly includes a second air bag strip. A first card strip is arranged at the bottom end of the side net. The width of the first card strip is smaller than the width of the side net. The first card strip is connected to the card slot in a matching manner. Four card slots are arranged on the bottom frame, and second air bag strips are arranged in all the four card slots. A third ventilation pipe is arranged inside the side wall of the bottom frame, and the second air bag strips in the four card slots are all communicated with the third ventilation pipe; a third air hole communicated with the third ventilation pipe is further arranged on the side wall of the bottom frame, and a valve core is arranged at the third air hole;

[0022] The second air bag strip adheres to the slot wall of the card slot in the non-inflated state, and protrudes from the top surface of the bottom frame in the inflated state.

[0023] The arrangement of the first air bag slag removal assembly facilitates ejecting and cleaning the accumulated pollutants in the card slot.

[0024] Further, second card strips are arranged on both sides of the side net. The height of the second card strip is smaller than the height of the side net, and the distance from the top end of the second card strip to the top end of the side net is equal to the distance from the bottom end of the second card strip to the bottom end of the side net; second sliding grooves slidingly matched with the second card strips are arranged on the side walls of the upright posts close to two adjacent side nets, and a second air bag slag removal assembly is arranged at the bottom of the second sliding groove; the second air bag slag removal assembly includes a third air bag strip. The third air bag strip adheres to the slot wall of the second sliding groove in the non-inflated state, and protrudes from the side surface of the upright post in the inflated state;

[0025] Inside the vertical column, there is a fourth air pipe connected to the third air bag strip. The lower end of the fourth air pipe is connected to the first air bag slag removal component through an air pipe connection component.

[0026] The setting of the second clamping strip and the second sliding groove strengthens the impact resistance of the side net, preventing other aquatic organisms in the water from bending the side net when preying on the aquatic organisms in the net cage. The second air bag slag removal component can effectively prevent pollutants from accumulating in the second sliding groove, facilitating the cleaning of the second sliding groove.

[0027] Furthermore, the air pipe connection component includes a fourth air hole provided on the bottom frame and connected to the third air pipe. A valve core is provided at the fourth air hole;

[0028] At the bottom end of the vertical column, there is a fifth air hole connected to the fourth air hole. One end of the fifth air hole close to the valve core is connected with a supporting column through a number of L-shaped brackets. The number of L-shaped brackets is distributed circumferentially along the axis of the fifth air hole. One end of the L-shaped bracket is fixedly connected to the vertical column, and the other end of the L-shaped bracket is fixedly connected to the end of the supporting column far from the fourth air pipe; and the supporting column is connected with the valve core in a matching manner. When the vertical column is connected to the bottom frame, the supporting column pushes open the valve of the valve core at the fourth air hole. At this time, the fourth air pipe is connected to the first air bag slag removal component through the fifth air hole;

[0029] Sealing square rings are also provided at both ends of the vertical column. The fifth air hole is located at the center of the sealing square ring; a square groove is provided on the bottom frame or the top frame and is connected with the sealing square ring in a matching manner; the surface of the sealing square ring is covered with a soft rubber layer; the height of the sealing square ring is greater than the depth of the square groove, and the cross-section of the square groove is an isosceles trapezoid. The upper base of the isosceles trapezoid is located at the end close to the vertical column, and the width of the upper base of the isosceles trapezoid is equal to the thickness of the sealing square ring.

[0030] The setting of the air pipe connection component enables the first air bag slag removal component and the second air bag slag removal component to be connected. Only through the third air hole can the inflation and deflation operations of the first air bag slag removal component and the second air bag slag removal component be completed, thus reducing the operation steps when cleaning and maintaining the net cage.

[0031] The setting of the sealing square ring and the clamping groove can strengthen the connection strength between the vertical column and the bottom frame or the top frame, and the sealing square ring can prevent water from entering when the fourth air hole is connected to the fifth air hole. It effectively isolates the erosion of water and prevents water from entering the second air bag strip and the third air bag strip, resulting in damage to the first air bag slag removal component and the second air bag slag removal component.

[0032] Furthermore, the vertical column is locked with the top frame and the bottom frame through a number of vertical bolts. The number of bolts is located inside the sealing square ring, and the number of bolts is distributed circumferentially along the axis of the vertical column; at the bolt hole of the bottom frame, there is a sealing rubber column for separating the bolt from water, and the sealing rubber column protrudes from the bottom surface of the bottom frame; the bolt hole of the top frame is sealed with wax.

[0033] After the net cage is assembled, the connection between the bottom frame and the upright columns can be maintained under normal circumstances without repeated disassembly and assembly. The rubber material of the sealing rubber column has good stability and is not easily damaged. At the same time, the sealing rubber column protrudes from the bottom surface of the bottom frame, which can play a buffering role. When the net cage is placed on the bottom of the water body or on the ground, it can avoid strong impact vibration of the frame structure and affect the structural strength of the entire net cage.

[0034] The method of wax sealing is simple to operate. After the melted wax solidifies, a hydrophobic layer can be formed on the surfaces of the bolts and bolt holes, and water erosion at the connection between the upright column and the top frame can be avoided. Heating and sealing are carried out again after each disassembly and assembly, effectively increasing the service life of the net cage.

[0035] A method for using an assembled aquaculture net cage includes the following steps:

[0036] S1: Insert the four upright columns into the corresponding square grooves on the upper part of the bottom frame respectively, lock them with bolts, and install the sealing rubber columns.

[0037] S2: Slide the bottom net into the first chute from the first opening, and use an inflation device to inflate the first airbag column and the first airbag strip through the second air hole. The elastic cords in the first airbag column and the third airbag column are stretched. The first airbag column is connected with the first limiting hole in a matching manner, the third airbag column is connected with the third limiting hole in a matching manner, and the first airbag strip abuts against and clamps the bottom net frame, so that the bottom net is fixedly connected with the bottom frame.

[0038] S3: Connect the side net with the second chute in a matching manner; the bottom end of the side net falls into the card slot of the bottom frame; connect the top frame with the four upright columns, and lock the upright columns and the top frame with bolts; use an inflation device to inflate the second airbag column through the first air hole. The elastic cord in the second airbag column is stretched, and the second airbag column is connected with the second limiting hole on the side net frame in a matching manner, so that the side net is fixedly connected with the top frame, and the net cage is obtained.

[0039] S4: Put the net cage into the water body for aquaculture. Before putting the net cage into the water body, use wax to seal the bolt holes of the top frame.

[0040] S5: When cleaning and repairing the net cage, break the wax, unscrew the bolts of the top frame, open the valve core at the first air hole, release the air in the second airbag limiting component. Under the action of the contraction of the elastic cord, the second airbag column retracts into the second opening, and the top frame and the side net are removed.

[0041] Open the valve core at the second air hole, release the air in the first airbag limiting component and the third airbag limiting component. Under the action of the contraction of the elastic cord, the first airbag column retracts into the first opening, and the third airbag column retracts into the third opening, and the bottom net is taken out; clean and repair the bottom net and the side net.

[0042] S6: Inflate the second airbag strip and the third airbag strip through the third air hole; make the second airbag strip protrude from the top surface of the bottom frame, push the pollutants in the card slot out of the card slot, and at the same time rinse the surface of the second airbag strip with clean water; make the third airbag strip protrude from the side surface of the column, push the pollutants in the second chute out of the second chute, and at the same time rinse the surface of the third airbag strip with clean water.

[0043] Inflate the first airbag column and the first airbag strip through the second air hole, make the first airbag column protrude from the side wall of the first opening, the first airbag strip protrude from the first chute, and the third airbag column protrude from the first airbag strip. The first airbag strip and the third airbag column push the pollutants in the first chute out of the first chute, and at the same time rinse the surfaces of the first airbag column, the first airbag strip and the third airbag column with clean water.

[0044] S7: After the cleaning is completed, open the valve cores at the second air hole and the third air hole, release the gas in the first airbag column, the first airbag strip, the second airbag strip and the third airbag strip, and then use the repaired bottom net and side net to perform steps S2 - S3, waiting for the next aquaculture use.

[0045] The beneficial effects of the present invention are as follows:

[0046] 1. The present invention forms a frame structure through the bottom frame, the top frame and the column, and then connects the side net and the bottom net to the frame structure to form a box body, making the transportation of the net cage planar and convenient for transportation; and this assembly method facilitates the disassembly of the side net and the bottom net. When the side net and the bottom net are damaged during aquaculture, it is convenient for maintenance or temporary replacement, reducing the maintenance time, thereby improving the aquaculture efficiency.

[0047] 2. Through the setting of the first airbag limiting component, the second airbag limiting component and the third airbag limiting component, the use of metal bolts in the connection between the side net or the bottom net and the frame structure is reduced, thereby reducing the corrosion probability of the connection by seawater or pollutants, reducing the probability of the entire net cage being disassembled or damaged, reducing maintenance, and increasing the service life.

[0048] 3. Through the setting of the second card strip and the second chute, the impact resistance of the side net is enhanced. At the same time, the second airbag slag removal component and the first airbag slag removal component set in the card slot can push out the pollutants accumulated in the card slot or the second chute during the use of the net cage, facilitating the cleaning of the pollutants and reducing the maintenance time of the net cage. Thereby improving the use efficiency of the net cage and reducing the cost of aquaculture. BRIEF DESCRIPTION OF THE DRAWINGS
