Assembled artificial fish reef and method for placing fish reef

Abstract

The present invention discloses an assembled artificial fish reef and a method for placing the fish reef, which includes a first fish reef component. The first fish reef component has a semi-floating member, and the first fish reef component also has a side frame body. The side frame body has a frame structure, and several auxiliary members are arranged inside the side frame body. The auxiliary members have a polygonal columnar structure, and the side surfaces of the auxiliary members are recessed inward. The hollow structure of the semi-floating member can provide buoyancy for itself. The larger upper hollow chamber generates greater buoyancy, which can prevent it from being easily overturned by sea waves and other large marine organisms. The circulation holes provided in the middle of the semi-floating member can, on the one hand, be used for water flow circulation to avoid the direct impact of water flow and reduce the influence of water flow on each semi-floating member. On the other hand, they can provide a habitat and shelter space for young fish, etc. Since there is a fish reef as a hidden shelter, the young fish can greatly reduce the misfortune of being preyed on by fierce fish, thereby improving the survival rate of young fish.

Description

Technical Field

[0001] The present invention relates to the technical field of artificial reef construction, and specifically to an assembled artificial reef and a method for placing the reef. Background Art

[0002] An artificial reef is an artificial object that is built underwater or on the seabed by human effort. This project can be used to improve the habitat environment of marine fish and other aquatic organisms, provide places for various aquatic organisms to forage, reproduce, grow and develop, etc., so as to protect wild fish and other aquatic organisms or improve fishery production capacity. With the continuous development of artificial reef construction, research on the environmental functions and fish aggregation effects of reefs has gradually been put forward. Through the construction of artificial reef areas, the ecological environment of traditional fishery habitats has been improved and restored, fishery resources have been restored, and the quality of economic aquatic products has been improved. Modern artificial reefs are also widely used.

[0003] An artificial reef device with an ecological synergistic effect disclosed in the prior art (CN109699549B) provides an artificial reef device with an ecological synergistic effect that can be combined with aquaculture equipment such as deep-water large cages. While generating an upwelling current, it accelerates the circulation of bottom water, provides fresh and sufficient nutrients inside the artificial reef device to attract fish, provides excellent habitats for sea treasures such as sea cucumbers and abalones, and at the same time takes away biological metabolic residues, improving the utilization rate of biological substances and energy of aquaculture equipment such as cages. However, its frame structure cannot achieve its own stability in the face of the scouring of sea waves, is extremely prone to damage to the device itself, and cannot well provide a suitable habitat for marine organisms. Summary of the Invention

[0004] The present invention provides a method for placing an assembled artificial reef, aiming to solve the problems that existing reefs are relatively heavy and large in volume, and consume a large amount of manpower and material resources during the placement process, and the placed reef has a larger surface area for attached organisms or semi-attached organisms in the ocean to inhabit.

[0005] The present invention also provides an assembled artificial reef, including:

[0006] A first reef component, the first reef component has a semi-floating member, the semi-floating member is internally provided with an upper hollow cavity and a lower hollow cavity, the internal space of the upper hollow cavity is larger than that of the lower hollow cavity, a circulation hole is provided in the middle of the semi-floating member, a plurality of semi-floating members are linearly arranged and connected by a rope body, the first reef component also has four side frames, one side surface of each side frame is fixedly connected to the semi-floating member arranged on the periphery by a rope body, and the ends of the four side frames are fixedly connected end to end by a chain to enclose a rectangular area;

[0007] The side frame body has a frame structure, and a plurality of auxiliary parts are arranged inside the side frame body. The auxiliary parts have a polygonal column structure, and the side surfaces of the auxiliary parts are concave inwards;

[0008] The design of the side frame, on the one hand, can form upwelling, accelerating flow, sluggish flow and other flow states around and inside the fish reef when it is placed in the ocean, so as to avoid these flow states causing uneven local force on the semi-floating parts in the side frame, and after the fish reef is placed, it is located below the sea level all year round, affected by the disturbance of nearby waves and the corrosion of seawater, which can easily cause damage to the internal parts of the fish reef, such as multiple semi-floating parts connected by ropes; on the other hand, the side frame can also control the distribution range of the semi-floating parts, and protect the sides of the semi-floating parts arranged in the array to avoid being damaged by ships and the ocean The auxiliary parts in the side frame can further provide habitat for marine life, and the layout of the side frame and its internal auxiliary parts can slow down the flow rate of nearby water flow, further reducing the possibility of large-scale movement of the entire first fish reef assembly in the water, and effectively preventing a large number of algae, shellfish, echinoderms and other fixed and semi-fixed organisms attached to its surface from falling off; on the other hand, the first fish reef assembly forms a local shading area under the water surface through the semi-floating bodies arranged in an array, which is conducive to providing habitat for light-avoiding organisms;

[0009] The hollow structure of the semi-floating component can provide buoyancy for itself. The larger upper hollow chamber generates greater buoyancy, which can prevent it from being easily overturned by waves and other large marine life, thereby causing the marine life attached to it to fall off, making the fish reef's protection of fish ineffective; the flow hole provided in the middle of the semi-floating component can be used for water circulation, avoiding the frontal impact of the water flow, reducing the influence of the water flow on each semi-floating component, and thereby preventing the semi-floating component from causing the entire first fish reef assembly to form an excessively large floating amount; on the other hand, it can provide a habitat and hiding space for young fish, etc. Since there is a fish reef as a hidden shelter, the young fish can greatly reduce the misfortune of being preyed upon by ferocious fish, thereby improving the survival rate of young fish.

[0010] The assembled artificial fish reef also includes a second fish reef component, the exterior of the second fish reef component is composed of three bottom-sinking plug-ins that are at an angle of 120 degrees to each other, the bottom-sinking plug-ins are provided with fluid-assisted holes, a bottom-sinking adjustment member is provided in a triangular area surrounded by the three bottom-sinking plug-ins, the bottom-sinking adjustment member has an adjustment main rod, three adjustment support rods are provided on the adjustment main rod, the adjustment support rods pass through the fluid-assisted holes, and the ends of the adjustment support rods are provided with limit blocks, and the adjustment main rod is connected to the bottom of the semi-floating member through a rope body; the assembled artificial fish reef also includes a counterweight block, which is connected to the bottom of the chain through an anchor rope;

[0011] The bottom-sinking plug plate has a symmetrical bent plate structure, a plug hole is provided at the central axis of the bottom-sinking plug plate, and plug connectors are provided on both sides of the bottom-sinking plug plate;

[0012] The adjusting support rod in the bottom-settling adjusting member can generate a certain displacement relative to the fluid auxiliary hole. However, due to the setting of the limiting block, the adjusting support rod will not disengage from the fluid auxiliary hole, thereby buffering the vertical floating effect of the semi-floating member above the bottom-settling member caused by various external factors, reducing the movement frequency of the bottom-settling member driven by the up-and-down floating of the upper semi-floating member, and keeping the bottom-settling member relatively stable at the bottom of the water area. The bottom-settling adjusting member is provided with a plurality of fluid auxiliary holes. Since most of the fluid auxiliary holes do not have the bottom-settling adjusting member inserted, fish can swim around the bottom-settling member, and it can also prevent the undercurrents on the seabed from directly impacting the bottom-settling insertion plate, affecting the fixing effect of the bottom-settling member and generating vibrations that affect the shellfish and other semi-attached organisms inhabiting on the fish reef. The design of the bottom-settling member can also cooperate with the counterweight to further fix the upper first fish reef component.

[0013] The counterweight has an upper counterweight base body and a lower counterweight base body that are symmetrically arranged up and down. The upper counterweight base body and the lower counterweight base body have a regular octagonal prism structure. Through holes are provided in the middle of the upper counterweight base body and the lower counterweight base body. A number of stepped platforms are provided on the upper counterweight base body and the lower counterweight base body, and through holes are provided on the stepped platforms. The upper counterweight base body and the lower counterweight base body are fixedly connected by a connecting plate. The connecting plate has an isosceles trapezoidal platform structure, and a number of grooves are symmetrically provided on both sides.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. For this assembled artificial fish reef, by designing the first fish reef component, on the one hand, it can avoid uneven local stress on the semi-floating member, which is extremely likely to cause damage to the internal components of the fish reef, such as multiple semi-floating members connected by ropes; on the other hand, the side frame can protect the sides of the semi-floating members arranged in an array from being impacted by ships and marine floating objects; on the other hand, the auxiliary members in the side frame can further provide a living space for marine organisms, can slow down the flow velocity when the nearby water flow passes through, and effectively prevent a large number of algae, shellfish, echinoderms and other sessile and semi-sessile organisms attached to its surface from falling off.

[0016] 2. For this assembled artificial fish reef, through the bottom-settling adjusting member in the second fish reef component, the movement frequency of the bottom-settling member driven by the up-and-down floating of the upper semi-floating member is reduced, and the bottom-settling member is kept relatively stable at the bottom of the water area; the multiple fluid auxiliary holes provided in the bottom-settling adjusting member can also prevent the undercurrents on the seabed from directly impacting the bottom-settling insertion plate, affecting the fixing effect of the bottom-settling member and generating vibrations that affect the shellfish and other semi-attached organisms inhabiting on the fish reef; the design of the bottom-settling member in the second fish reef component can cooperate with the counterweight to further fix the upper first fish reef component.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] See also Figure 1-5 The assembled artificial fish reef comprises: a first fish reef assembly 1, the first fish reef assembly 1 has a semi-floating part 11, a plurality of semi-floating parts 11 are linearly arranged and connected by a rope body 13, the first fish reef assembly 1 also has a side frame body 12, the ends of the side frame body 12 are fixedly connected end to end by a chain 14, a counterweight block 3, the counterweight block 3 is connected to the bottom of the chain 14 by an anchor rope 16, an upper hollow cavity 17 and a lower hollow cavity 18 are arranged inside the semi-floating part 11, the internal space of the upper hollow cavity 17 is larger than that of the lower hollow cavity 18, a flow hole 19 is arranged in the middle of the semi-floating part 11, the side frame body 12 has a frame structure, a plurality of auxiliary parts 15 are arranged inside the side frame body 12, the auxiliary part 15 has a polygonal column structure, and the side surface of the auxiliary part 15 is concave inwardly;

[0031] The design of the side frame 12 can, on the one hand, form upwelling, accelerating flow, stagnant flow and other flow states around and inside the fish reef when it is placed in the ocean, so as to avoid these flow states causing uneven stress on the semi-floating parts 11 in the side frame 12, and after the fish reef is placed, it is located below the sea level all year round, affected by the disturbance of nearby waves and the corrosion of seawater, which can easily cause damage to the internal parts of the fish reef, such as the multiple semi-floating parts 11 connected by the rope body 13; on the other hand, the side frame 12 can also control the distribution range of the semi-floating parts 11, and protect the sides of the semi-floating parts 11 arranged in an array to avoid being damaged by ships. and collision with floating objects in the ocean; on the other hand, the auxiliary parts 15 in the side frame 12 can further provide a habitat for marine organisms, and the layout of the side frame 12 and the auxiliary parts 15 inside it can slow down the flow rate of the nearby water flow, further reducing the possibility that the entire first fish reef component 1 may move over a large range in the water, and effectively preventing a large number of algae, shellfish, echinoderms and other fixed and semi-fixed organisms attached to its surface from falling off; on the other hand, the first fish reef component 1 forms a local shading area below the water surface through the semi-floating parts arranged in an array, which is conducive to providing a habitat for light-avoiding organisms;

[0032] The hollow structure of the semi-floating member 11 can provide buoyancy for itself. The larger upper hollow cavity 17 generates greater buoyancy, which can prevent it from being easily overturned by sea waves and other large marine organisms, thus causing the marine organisms attached to it to fall off and rendering the protection of the fish reef ineffective for fish. The circulation holes 19 provided in the middle of the semi-floating member 11 can, on the one hand, be used for water flow circulation to avoid the frontal impact of water flow, reduce the influence of water flow on each semi-floating member 11, and further prevent the semi-floating member 11 from causing excessive floating of the entire first fish reef assembly 1. On the other hand, it can provide a habitat and hiding space for young fish, etc. Since there is a fish reef as a hiding and sheltering place, the young fish can greatly reduce the misfortune of being preyed on by fierce fish, thereby increasing the survival rate of young fish.

[0033] Please refer to Figure 1 and Figure 6-9 As shown in FIGS. and, the second fish reef assembly 2. The outside of the second fish reef assembly 2 is composed of three sinking bottom plates 23 that are mutually at an angle of 120°. Fluid auxiliary holes 24 are provided on the sinking bottom plates 23. A sinking bottom adjusting member 22 is provided in the triangular area surrounded by the three sinking bottom plates 23. The sinking bottom adjusting member 22 has an adjusting main rod 29. Three adjusting support rods 25 are provided on the adjusting main rod 29. The adjusting support rods 25 pass through the fluid auxiliary holes 24. A limiting block 26 is provided at the end of the adjusting support rod 25. The adjusting main rod 29 is connected to the bottom of the semi-floating member 11 through a rope 13. The sinking bottom plate 23 has a symmetric bent plate structure. A plugging hole 27 is provided at the central axis of the sinking bottom plate 23. Plug connectors 28 are provided on both sides of the sinking bottom plate 23;

[0034] The adjusting support rods 25 in the sinking bottom adjusting member 22 can generate a certain displacement relative to the fluid auxiliary holes 24. However, due to the setting of the limiting blocks 26, the adjusting support rods 25 will not disengage from the fluid auxiliary holes 24. As a result, the vertical floating effect of the semi-floating member 11 above the sinking bottom member 21 caused by various external factors is buffered, reducing the movement frequency of the lower sinking bottom member 21 driven by the up and down floating of the upper semi-floating member 11, and keeping the sinking bottom member 21 sinking stably at the bottom of the water area. The multiple fluid auxiliary holes 24 provided in the sinking bottom adjusting member 22, since most of the fluid auxiliary holes 24 do not have the sinking bottom adjusting member 22 inserted, enable fish to swim around the sinking bottom member 21 and can also prevent the undercurrents on the seabed from directly impacting the sinking bottom plates 23, affecting the fixing effect of the sinking bottom member 21 and generating vibrations that affect the shellfish and other semi-attached organisms inhabiting on the fish reef. The design of the sinking bottom member 21 can also cooperate with the counterweight 3 to further fix the upper first fish reef assembly 1.

[0035] Please refer to Figure 1 and Figure 10, the counterweight 3 has an upper counterweight base body 32 and a lower counterweight base body 33 which are symmetrically arranged up and down. The upper counterweight base body 32 and the lower counterweight base body 33 have a regular octagonal prism structure. Through holes are provided in the middle of the upper counterweight base body 32 and the lower counterweight base body 33. A number of stepped platforms 310 are provided on the upper counterweight base body 32 and the lower counterweight base body 33. Through holes are provided in the stepped platforms 310. The upper counterweight base body 32 and the lower counterweight base body 33 are fixedly connected by a connecting plate 34.
