Description

Technical Field

[0001] The invention relates to a fish reef and a preparation method thereof, and in particular to an anti-sinking and anti-movement multifunctional ecological fish reef and a preparation method thereof. Background Art

[0002] Artificial reefs are structures set up artificially in the sea. Their purpose is to improve the ecological environment of the sea, create a good environment for marine life to live, and provide a place for fish to reproduce, grow, forage and shelter from enemies, so as to achieve the purpose of protection, proliferation and increase of fish catch.

[0003] In the prior art, artificial fish reefs such as train sleeper cars, old ship hulls, and old car bodies have been deployed. However, during the implementation process, it was found that large reefs such as train cars were found to be silted, and small reefs such as old ship hulls and old car bodies drifted. They are not suitable for use as artificial fish reefs for breeding, and are also unable to adapt to the growth of marine delicacies such as sea cucumbers. Summary of the invention

[0004] In order to solve the deficiencies of the above-mentioned technologies, the present invention provides a multifunctional ecological fish reef that prevents sinking and migration and a preparation method thereof.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: an anti-sinking and anti-movement multifunctional ecological fish reef, comprising a box body, the box body is in a cubic shape, the top surface of the box body is open, the bottom surface of the box body is fixedly connected to a suction base that can be adsorbed on the seabed, and the bottom surface of the box body is closed by the suction base;

[0006] Four panels are installed on each side of the box body, and the four panels are arranged in a field shape by being spaced apart by beams and columns. One or more circular flow holes are opened in the middle of each panel to facilitate the circulation of seawater; square flow holes are also opened on the two panels located on the lower side, and the square flow holes are located below the circular flow holes; the square flow holes are convenient for the circulation of seawater to the base cage at the bottom of the box body and for sea cucumbers to crawl in and out of the box body; the circular flow holes and the square flow holes can form a swirling upwelling in the fish reef, which is conducive to the aggregation and survival of various marine organisms for feeding;

[0007] The inverted suction base is integrally formed, and includes an inverted box area surrounded by upright panels. The top of the inverted box area is closed and the bottom is open. The inverted box area is square. There are four inverted box areas, which are arranged in a field shape, and two adjacent inverted box areas are separated by upright panels. The inverted suction base is on the mud and sand on the seabed. As the box body sinks, the upright panels are inserted into the mud and sand until the air in the inverted box area is completely discharged, forming a vacuum sealed body, which is fixed by suction on the mud and sand on the seabed without sinking or drifting, and is suitable for sea cucumbers to hibernate in winter and summer.

[0008] Furthermore, the panel is made of magnesite cement, and basalt fiber is mixed in the magnesite cement.

[0009] Furthermore, columns are arranged at the four vertical edges of the box body, and slots are provided on the columns, and the edges of the panel can be stuck in the slots to fix the panel and the columns.

[0010] Furthermore, crossbeams are arranged at the transverse edges of the top and bottom surfaces of the box body, and sockets are opened on the crossbeams at positions corresponding to the columns. The columns are inserted into the sockets, and the crossbeams and the columns are fixed by gluing.

[0011] Furthermore, the upright column is inserted into the inverted suction base through the crossbeam socket on the bottom surface of the box body, and the upright column is flush with the upright panel, and a slot for fixing the inverted box area panel is opened on the upright column.

[0012] Furthermore, a semi-covered cave-type base cage suitable for the growth of sea cucumbers is placed at the bottom of the box, and a multifunctional base cage is hung at the upper middle part of the box.

[0013] A method for preparing a multifunctional ecological fish reef that prevents sinking and migration, comprising the following steps:

[0014] Step 1: Select three crossbeams and eight solid columns that form a rectangle, punch sockets at the corners and midpoints of each crossbeam, arrange the three crossbeams up and down, and insert the columns into the sockets from top to bottom, so that the three crossbeams are located at the top, middle and bottom of the columns respectively, wherein the crossbeam located at the bottom of the column is separated from the bottom of the column by the distance of the inverted suction base; thus, the frame of the box is prepared;

[0015] Step 2: pour magnesite cement in the mold of the inverted suction base, and mix basalt fiber in the magnesite cement to make the inverted suction base, and reserve sockets for inserting columns at the four corners and the center line of the edge of the inverted suction base; the inverted suction base is installed at the bottom of the box frame, and the columns growing out of the box frame are inserted into the sockets reserved on the inverted suction base, and then the inverted suction base and the box frame are firmly connected by gluing; the inverted suction base is surrounded by an inverted box area surrounded by vertical panels, and there are four inverted box areas, which are arranged in a field shape, and the two adjacent inverted box areas are separated by vertical panels; the inverted suction base is on the seabed mud and sand, and the vertical panels are inserted into the mud and sand as the box sinks until the air in the inverted box area is completely discharged, forming a vacuum seal, which is fixed by suction buckles on the seabed mud and sand without silting or drifting;

[0016] Step 3: Pour magnesite cement into the mold and mix basalt fibers in the magnesite cement to prepare 16 panels. One or more circular circulation holes are opened on each of the 16 panels for seawater to flow through. Square circulation holes are also opened on 8 of the 16 panels, with the square circulation holes located below the circular circulation holes. The square circulation holes are for seawater to flow through the semi-sheltered cave-like cages for sea cucumbers to grow;

[0017] Step 4: Fit the 16 panels onto the four sides of the box body through the card slots on the columns. Since the cross of the cross beam and the column makes each side of the box body in a grid pattern, the strength of the side of the box body is enhanced. Therefore, the panels are installed in a grid pattern on the sides of the box body. Among them, the 8 panels with square circulation holes are installed in the lower part of the box body, and the remaining 8 panels without square circulation holes are installed in the upper part of the box body; and further bond the panels and the columns firmly by gluing. Thus, the anti-settlement and anti-shift multi-functional ecological fish reef is prepared.

[0018] The panels use magnesite cement and the method of mixing basalt fibers to improve strength. The advantages are: the tensile strength of basalt fibers is higher than that of steel bars; the weight of basalt fibers is less than that of steel bars; the erosion of basalt fibers by cement is much lower than that of steel bars. In coastal areas directly exposed or vulnerable to the influence of seawater and sea breeze, the use of basalt fibers can greatly extend the service life of magnesite cement products. The tensile strength of basalt fibers: 3000 - 4800 MPa, which is better than that of steel bars by 370 - 410 MPa.

[0019] There are 4 self-sealing inverted box areas in the inverted suction base, and the buckling area is 9 ㎡, with sufficient landing area. It buckles and sucks to fix the muddy ground. After the reef body is put in, there is little subsidence, no tipping and no sliding. The principle of the self-sealing vacuum suction and fixation technology is similar to that of a suction anchor. After the base of the reef body contacts the sea mud, with the action of gravity, the reef body gradually sinks. During the process, the gas in the 4 sealed inverted box areas will be emptied, and the water pressure is used to make the base of the reef body closely fit with the seabed. At the same time, by controlling the weight of the reef body, its bearing limit with the seabed sediment reaches balance, so as to ensure the firmness and stability of the reef body.

[0020] The components of the present invention are connected by snap slots and bonded with special glue at the joints to form an integrated reef, which is firm and stable and convenient for installation and transportation.

[0021] In the inner bottom of the reef body of the present invention, 16 semi-sheltered cave-like cages mainly suitable for the growth of sea cucumbers are placed, and 14 multi-functional cages are hung in the middle and upper parts. Coupled with its non-silting, non-drifting nature, it is more suitable for the cultivation of sea cucumbers and other marine treasures.

[0022] Through the product tracking test in Changdao Ocean Ranch, the present invention has no powdering, back-halogenation, back-alkalization in the past three years, and there is no obvious change in strength. The application effect of the inverted box technology is obvious, and the attachment of marine organisms reaches 70% within three months.

[0023] The present invention adopts new materials and new structures, has a wide shadow area, and has a good swirling upwelling effect, which is conducive to the aggregation and foraging of various marine organisms for survival, and can obviously gather fish, which is beneficial to the protection and restoration of the marine ecological environment and the improvement of the efficiency of seafood resources. In addition, the raw materials have no emissions, achieving zero solid and liquid emissions, which meets national environmental protection requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In the figure: 1. box body; 2. inverted suction base; 3. panel; 4. crossbeam; 5. column; 6. circulation hole 7. inverted box area. DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] like Figure 1 The intermittent vacuum crystallization process of ferrous sulfate shown includes a box 1, which is in a cubic shape, the top surface of the box is open, and the bottom surface of the box is fixedly connected to a suction base 2 that can be adsorbed on the seabed, and the bottom surface of the box is closed by the suction base;

[0028] Four panels 3 are installed on each side of the box body, and the four panels are spaced apart by crossbeams 4 and columns 5 so that the four panels are distributed in a field shape. One or more circular flow holes 6 are opened in the middle of each panel to facilitate the circulation of seawater; square flow holes are also opened on the two panels located on the lower side, and the square flow holes are located below the circular flow holes; the square flow holes are convenient for circulating seawater for the base cage at the bottom of the box body; the circular flow holes and the square flow holes can form a swirling upwelling in the fish reef, which is conducive to the gathering and foraging survival of various marine organisms.

[0029] The inverted suction base is integrally formed, and includes an inverted box area 7 surrounded by upright panels. The top of the inverted box area is closed and the bottom is open. The inverted box area is square. There are four inverted box areas with a total coverage area of ​​9 square meters. The four inverted box areas are arranged in a field shape, and two adjacent inverted box areas are separated by upright panels. The inverted suction base is on the muddy ground on the seabed. As the box body sinks, the upright panels are inserted into the muddy ground until the air in the inverted box area is completely discharged, forming a vacuum sealed body, which is fixed by suction on the muddy ground on the seabed without silting or drifting.

[0030] The mass (weight) of the fish reef body is determined according to the bearing capacity of the seabed mud. The pressure (intensity) of the fish reef can be calculated through the density (buoyancy) of seawater, the water flow rate, the reef resistance and the bottom area of ​​the reef body. By adjusting the mass of the fish reef body, the fit between the fish reef body and the seabed can reach the most stable state.

[0031] Specifically, according to the water pressure formula p=ρgh (p is pressure, ρ is liquid density, the density of water is 1×10^3kg / m^3, g is the acceleration of gravity, which is 9.8N / kg, and h is the height from the pressure point to the liquid surface. The water depth of this reef area is 18m), the pressure of the bottom surface of a single fish reef on the seabed is calculated (the water pressure at a depth of 18m plus the weight of the reef minus the buoyancy, and finally divided by the bottom area of ​​9㎡) to be 1.8×10^5Pa, and the pressure on the seabed is 1.72×10^6N, which is about 170 tons.

[0032] The water resistance is Rx=Cdx0.5xSxV^2. Considering that the Cd coefficient is 1.6, the ρ density is 1025 kg / cubic meter, the S area is 6 square meters, and the V speed is 3 meters / second, the water resistance is Rx=44280N. Considering that the sea water depth is 18 meters and the pressure generated by its own weight is 1.72×10^6N, the static friction is the friction coefficient 0.5*1.72×10^6N=8.6x10^5N. Static friction / water resistance=19.42 is much larger than the required safety factor of 1, so the reef no-slip condition is met.

[0033] The material of panel 3 is magnesite cement, and basalt fiber is mixed in magnesite cement. The present invention adopts magnesite cement, and its product quality is better than ordinary cement, the strength is 2.5 times that of ordinary concrete, and the volume is 70% of ordinary concrete. The specific gravity can be adjusted appropriately according to the bottom conditions to improve the strength. Basalt shreds are used, and the national standard "Chopped Basalt Fiber for Cement Concrete and Mortar" GB / T2365-2009 is implemented.

[0034] The four vertical edges of the box body are all provided with upright posts 5, and the upright posts are provided with slots, and the edges of the panel can be stuck in the slots to fix the panel and the upright posts.

[0035] The transverse edges of the top and bottom surfaces of the box body are all provided with crossbeams 4, and the crossbeams are provided with sockets corresponding to the positions of the columns, the columns are inserted into the sockets, and the crossbeams and the columns are fixed by glue.

[0036] The upright column is inserted into the inverted suction base through the crossbeam socket on the bottom surface of the box body, and the upright column is flush with the vertical panel, and a card slot for fixing the inverted box area panel is opened on the upright column.

[0037] A semi-covered cave-type base cage suitable for the growth of sea cucumbers is placed at the bottom of the box, and a multifunctional base cage is hung in the middle and upper part of the box.

[0038] The method for preparing a multifunctional ecological fish reef that prevents sinking and migration comprises the following steps:

[0039] Step 1: Select three beams 4 forming a 100mm×50mm rectangle and eight solid columns 5 with a diameter of 63mm, punch a socket with a diameter of 63mm at the corner and midpoint of each beam, arrange the three beams up and down, and insert the columns into the sockets from top to bottom, so that the three beams are located at the top, middle and bottom of the column respectively, wherein the beam located at the bottom of the column is separated from the bottom of the column by the distance of the inverted suction base; thus, the frame preparation of the box body is completed;

[0040] Step 2: pour magnesite cement in the mold of the inverted suction base, and mix basalt fiber in the magnesite cement to make the inverted suction base 2, and reserve sockets for inserting columns at the four corners and the center line of the edge of the inverted suction base; the inverted suction base is installed at the bottom end of the box frame, and the columns 5 growing out of the box frame are inserted into the sockets reserved on the inverted suction base, and then the inverted suction base is firmly connected to the box frame by gluing;

[0041] Step 3: pouring magnesite cement in a mold, and mixing basalt fiber in the magnesite cement to prepare 16 panels 3, opening one or more circular flow holes 6 on the 16 panels for seawater circulation, and opening square flow holes on 8 of the panels, so that the square flow holes are located below the circular flow holes, and the square flow holes are used for the semi-silted cave-type base cage for the growth of sea cucumbers to circulate seawater;

[0042] Step 4: Fit the 16 panels to the four sides of the box through the slots on the columns. The intersection of the beams and the columns makes each side of the box in a field shape to enhance the strength of the sides of the box. Therefore, the panels are installed in a field shape on the sides of the box. Among them, 8 panels with square circulation holes are installed in the lower part of the box, and the remaining 8 panels without square circulation holes are installed in the upper part of the box. The panels are further firmly bonded to the columns by gluing. At this point, the preparation of the anti-sinking and anti-movement multifunctional ecological fish reef is completed.
