Description

Technical Field

[0001] The present invention belongs to the technical field of fishery engineering facilities, and relates to a combined cheval-de-frise artificial fish reef, in particular to a combined new artificial fish reef - a cheval-de-frise ecological attachment base. Background Art

[0002] Artificial fish reefs are an effective technical measure for protecting and enhancing offshore fishery resources at present. They have multiple functions such as conserving fishery resources, restoring the marine ecological environment, stabilizing the marine ecosystem, adjusting the structure of the marine fishery industry, and driving the development of related industries. At present, artificial fish reefs are mainly divided into square fish reefs, cross-shaped fish reefs, triangular fish reefs, frustum-shaped fish reefs, semi-circular fish reefs, frame-shaped fish reefs, trapezoidal fish reefs, ship-shaped fish reefs, etc. according to their structures. Most of the artificial fish reefs with a frame structure have a small surface area, which is not particularly conducive to the growth of attached organisms. In addition, the current artificial fish reefs are generally arranged in a form of complete embedding or scattered layout, and their layout forms are relatively single and difficult to be flexibly combined.

[0003] Therefore, it is of great practical significance to develop an artificial fish reef that can be flexibly combined and is conducive to the growth of attached organisms. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects that the existing artificial fish reefs are not conducive to the growth of attached organisms, have a relatively single layout form, and are difficult to be flexibly combined, and to provide an artificial fish reef that can be flexibly combined and is conducive to the growth of attached organisms.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A combined cheval-de-frise artificial fish reef includes a front plate and a rear plate;

[0007] Both the front plate and the rear plate are flat plate-like structures integrally in a U-shaped shape. The two sides of the U-shaped flat plate-like structure are support members, and the middle part is a connecting member for connecting the two support members;

[0008] The connecting members of the front plate and the rear plate are connected to each other on the side away from the support members to form a triangular cheval-de-frise structure;

[0009] One or more conical structures are connected to the outer side of the front plate, and the bottom surface of the conical structure is connected to the outer side surface of the front plate;

[0010] Holes I and II that match the two support members on the front plate are respectively opened on the two support members of the rear plate. Inserting the two support members of the front plate of another combined cheval-de-frise artificial fish reef into the holes I and II on the rear plate can complete the fixation of the two combined cheval-de-frise artificial fish reefs;

[0011] The included angle between the front plate and the rear plate is 30°, 60° or 90°;

[0012] A plurality of combinable chevaux-style artificial fish reefs with angles of 30°, 60° and 90° between the front plates and the rear plates form a set of chevaux-style artificial fish reef kits that can be deployed individually or in combination to meet the needs of changing coasts and different slopes.

[0013] The combined chevaux-style artificial fish reef of the present invention can reasonably expand the surface area for biological growth on the basis of traditional reef piles, can effectively and reasonably cater to the attachment activities of reef area organisms, and at the same time, the hollowed-out area at the bottom can often provide a good shelter for some fish larvae, play a role in gathering fish schools, and has potential economic value; the combined chevaux-style artificial fish reef can not only provide a good environment for attached organisms, but also has a beautiful shape, saves most of the stones, and the conical structure is similar to the form of rope breeding (attached and growing organisms can grow rapidly on rough nylon ropes, waste plastic barrels and broken large pieces of sand and gravel), optimizes their living environment under a reasonable breeding space, is conducive to increasing the attachment opportunities of hook shell larvae, increasing the effective attachment base area, and can also reduce the impact of sea currents; the expansibility is excellent, and can be extended and stacked to create a new type of fish reef system with linkage and space. In addition, its special structure can not only play a certain role in wave resistance, but also the semi-enclosed space between the front and rear plates in the chevaux-style artificial fish reef shields the influence of external water flow on the internal space to a certain extent, and can guide the flow direction in the space to help the growth of attached organisms, and has great application prospects.

[0014] As the preferred technical solution:

[0015] The above-mentioned combinable chevaux-style artificial reef is characterized in that the height of the conical structure is perpendicular to the front plate. The protection scope of the present invention is not limited thereto, and those skilled in the art can set the conical structure according to actual needs.

[0016] In the above-mentioned combinable barricade-type artificial fish reef, multiple (6, the number can be specifically adjusted by a person skilled in the art) conical structures are evenly distributed on the connecting member of the front plate. There is a certain relationship between the spacing, height and bottom radius of the conical structures, and the ratio of the three is 2:5:6, which is adjusted according to the size of the plane. For example, when the connecting plane is 150cm long and 100cm wide, the radius is 10cm, the spacing should be 25cm, and the height is 30cm.

[0017] In the above-mentioned combinable chevaux-de-force type artificial fish reef, the connecting components of the front plate and the rear plate are respectively provided with corresponding groups (6 to 12 groups, the number can be specifically adjusted by a person skilled in the art) of plug holes, each group of plug holes corresponds to each other and a porous nitrifying bacteria house is arranged therein.

[0018] As described above, when the combinable chevaux-barrier type artificial fish reef is placed on a horizontal surface, the porous nitrifying bacteria house is in a horizontal state, which can prevent the porous nitrifying bacteria house from falling.

[0019] A combinable chevaux-style artificial fish reef as described above, the porous nitrifying bacteria house is a hollow cylindrical structure with many small holes distributed on the side, which can enhance the air permeability and water permeability of the bacteria house, and is conducive to the cultivation and production of nitrifying bacteria. The bacteria house is also called a bacterial ring, which is a very efficient material for cultivating nitrifying bacteria, and nitrifying bacteria live in an oxygen-rich water environment or among sand and gravel. The main function in the water is to decompose toxic and harmful ammonia nitrogen compounds and purify the water quality. Good water quality can promote the metabolism of aquatic organisms and excrete harmful substances in the body. And effectively increase the dissolved oxygen content in the water, can adsorb harmful heavy metal elements in the water to a certain extent, and provide a suitable living place for beneficial nitrifying bacteria.

[0020] As described above, a combinable barricade-type artificial fish reef has a width direction along the connecting edge of the front plate and the rear plate, the width of the front plate is the same as that of the rear plate and the two are connected into a smooth whole, and the width is 2m; the height of a single combinable barricade-type artificial fish reef is 3m; the thickness of the front plate and the rear plate is 30~50cm, and the spacing between the vertices of adjacent conical structures is 50cm. Only a feasible specific solution is given here, and those skilled in the art can set the parameters according to actual needs.

[0021] The above-mentioned combinable chevaux-de-force type artificial fish reef is characterized in that the connection between the front plate and the rear plate has a smooth transition;

[0022] The whole formed by connecting the front plate and the rear plate is cast by cement;

[0023] The conical structure is made of secondary processed waste building materials (of course, cement can also be directly used for casting. The secondary processing of waste building materials can greatly reduce production costs and save energy and reduce emissions). The surface of the conical structure is rough, which improves the success rate of the hook shell larvae.

[0024] In the above-mentioned combinable barricade type artificial fish reef, the angle between the front plate and the rear plate is 30°, 60° or 90°. The angle between the front plate and the rear plate is not limited to this, and only a feasible technical solution is given here. Those skilled in the art can appropriately adjust the angle between the front plate and the rear plate in actual application.

[0025] As described above, a combinable chevaux-style artificial fish reef, a plurality of combinable chevaux-style artificial fish reefs with angles of 30°, 60° and 90° between the front plate and the rear plate form a set of combinable chevaux-style artificial fish reef kits. The combinable chevaux-style artificial fish reefs with different angles can be freely combined to meet the needs of variable coasts and slopes.

[0026] The above-mentioned combined chevaux-de-force type artificial reefs can be used in the following operating specifications (they can be arranged on slopes or port areas):

[0027] Since the reproduction period of most of the attached organisms is concentrated in spring and summer (March to August), the release time should be based on the different conditions of the year.

[0028] When the bottom of the water area where the deployment is carried out is an open and relatively flat sandy bottom, stone bottom, muddy bottom, sand and gravel mixed bottom or mud and sand mixed bottom, the deployment can be carried out directly according to the direction of the water flow. The flow-facing surface of the attachment base can be changed flexibly during deployment, and even stacked deployment can be carried out, which is conducive to the gathering of aquatic organisms.

[0029] When the bottom of the sea area for deployment is a sandy bottom, stone bottom, muddy bottom, sand and gravel mixed bottom or mud and sand mixed bottom with a relatively gentle slope, stacked deployment can be carried out. When deploying, the flow-facing surface of the attachment base is adjusted to the side to face the flow, so that the water flow can flow better, thereby better carrying nutrients.

[0030] When the bottom of the sea area where the deployment is carried out is a rugged sand-gravel mixture or mud-sand mixture, different specifications of attachment bases can be used for deployment according to the size of the slope. At the same time, there are two ways to operate in this area:

[0031] 1. Directly release the attachment bases at different angles suitable for different terrains in a disconnected state. When releasing, the attachment bases will face the current sideways to reduce resistance. This method can maintain the original bottom water flow direction of the sea area as much as possible, save the number of reefs to be released, and greatly save costs.

[0032] 2. According to the slope of different terrains, select attachment bases with corresponding applicable angles for combined placement. When placing, the attachment bases should face the flow directly. This method is conducive to centralized management, efficient use of terrain space, and can attract other organisms to gather.

[0033] Beneficial effects:

[0034] (1) The combinable barricade-type artificial fish reef of the present invention has a reasonable expansion of the surface area for the growth of attached organisms on the basis of traditional reef piles, which can effectively and reasonably cater to the attachment activities of reef organisms. At the same time, the hollowed-out areas at the bottom can often provide a good shelter for some fish larvae, play a role in gathering fish schools, and have potential economic value;

[0035] (2) The combinable chevaux-style artificial fish reef of the present invention not only provides a good environment for attached organisms, but also has a beautiful shape and saves most of the stones. The conical structure is similar to the form of rope farming, which optimizes the living environment of the organisms under a reasonable farming space.

[0036] (3) The structure of the combinable barricade-type artificial fish reef of the present invention can be designed into different inner angle styles, and the angle of the lower inner angle can be flexibly changed to adapt to the changing coast and different slopes. The shore-facing surface of the reef body is designed with a connectable groove, so that the reef body can be extended and stacked, and it is no longer completely embedded or dispersed like traditional fish reefs. A new type of fish reef system with linkage and space is created, and it can also play a role in wave resistance to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, it should not be construed as a limitation to the present invention.

[0047] Embodiment 1

[0048] A combinable chevaux - de - frise - type artificial fish reef, as Figures 1 to 3 shown, includes a front plate 1 and a rear plate 2;

[0049] Both the front plate 1 and the rear plate 2 are flat plate - like structures integrally in a U - shape. The two sides of the U - shaped flat plate - like structure are support members 3, and the middle part is a connecting member 4 for connecting the two support members;

[0050] The connecting members of the front plate and the rear plate are connected to each other on the side away from the support members to form a triangular chevaux - de - frise - like structure, and the included angle between the front plate and the rear plate is 30°. Taking the connecting edge of the front plate 1 and the rear plate 2 as the width direction, the width of the front plate 1 is the same as that of the rear plate 2 (2 m), and the two are connected into a smooth whole (the overall height is 3 m), and the connection between the front plate 1 and the rear plate 2 is smoothly transitioned;

[0051] Six conical structures 5 are evenly connected to the outside of the connecting member of the front plate (the distance between the vertices of adjacent conical structures is 90 cm, the height of the conical structure is 60 cm, and the radius of its bottom surface is 20 cm). The bottom surface of the conical structure 5 is connected to the outer side surface of the front plate, and the height of the conical structure 5 is perpendicular to the front plate 1;

[0052] The whole formed by connecting the front plate 1 and the rear plate 2 is made of cement casting, and the thickness of the front plate 1 and the rear plate 2 is 30 - 50 cm;

[0053] The conical structure 5 is made by secondary processing of waste building materials, and the surface of the conical structure 5 is rough;

[0054] Twelve corresponding groups of sockets are respectively provided on the connecting members of the front plate 1 and the rear plate 2. Each group of sockets 6 corresponds to each other and a porous nitrifying bacteria house 6 (a hollow cylindrical structure with many small holes on the side) is arranged therein. When the combinable chevaux-de-lis artificial fish reef is placed on a horizontal plane (at this time, only one point of the front plate 1 and the rear plate 2 is in contact with the ground), the porous nitrifying bacteria house 6 is in a horizontal state.

[0055] The two supporting members 3 on the rear plate 2 are respectively provided with holes I 7 and II 8 matching the two supporting members on the front plate. The two supporting members of the front plate of another combinable chevaux-style artificial fish reef are inserted into the holes I 7 and II 8 on the rear plate to complete the fixation of the two combinable chevaux-style artificial fish reefs.

[0056] Example 2

[0057] A combinable barricade-type artificial fish reef, such as Figures 4 to 6 As shown, its structure is basically the same as that of embodiment 1, except that the angle between the front plate and the rear plate is 60°.

[0058] Example 3

[0059] A combinable barricade-type artificial fish reef, such as Figures 7-9 As shown, its structure is basically the same as that of embodiment 1, except that the angle between the front plate and the rear plate is 90°.

[0060] Example 4

[0061] A combinable barricade-type artificial fish reef, such as Fig.10 As shown, its structure is basically the same as that of Example 1, except that when the combinable barricade-type artificial fish reef is placed on a horizontal plane, the bottom planes of the front plate 1 and the rear plate 2 are in contact with the ground.

[0062] Example 5

[0063] The configurable and combinable chevaux-style artificial fish reef kit includes the configurable chevaux-style artificial fish reefs as described in Example 1, Example 2 and Example 3. The schematic diagram of the combination of the three in pairs is as shown in FIG. Figures 11 to 13 As shown, the hole is a blind hole at this time, and the size and type of the hole can also be designed according to actual needs (such as setting it as a through hole) so that the front plate of the jack is partially or completely penetrated;

[0064] The three angle combinations of the combinable barricade-type artificial fish reef can be freely combined, and the specifications of the combinable barricade-type artificial fish reef can be increased or decreased in proportion according to the actual situation. The front plate is indented from both sides to the middle, so that the front section of the bracket is formed in a trapezoidal design, which just corresponds to the through hole of the rear plate, that is, the trapezoidal bayonet;

[0065] The semi-covered structure of the above-mentioned combinable chevaux-de-lis artificial fish reef can also provide shelter for many juvenile fish, and the concrete material is relatively inexpensive. The triangular stable structure on the side enhances the wave resistance and is conducive to the growth of a large number of epiphytic algae on the base surface. It mainly provides an attachment base for oysters, mussels and corals, while taking into account the functions of purifying the water environment and gathering fish and other benthic organisms.

[0066] The combined chevaux-style artificial fish reef of the present invention has the following advantages: 1) by changing the specifications of the lower inner angle, it can better adapt to various complex terrains and has flexible combination; 2) the addition of the through hole on the rear plate support (i.e. the slot matching the front plate support) is convenient for increasing stability when a single reef is combined into a large reef pile; 3) the innovative design concept of the chevaux-style can not only effectively resist the impact of the ocean current, but also has very high stability, and the cost of the materials used is reduced compared with most traditional fish reefs; 4) in artificial fish reefs (ecological attachment 1) It combines the environmental protection concept of waste recycling, and the conical structure maximizes the attachment area and makes reasonable use of space; 2) The main idea of ​​the proliferation of attached organisms is to further consider the overall water quality environment. There are tent-shaped hiding caves in the lower part of the reef, which can attract more kinds of organisms to live here; 3) In the middle between the front and the back, a crossbeam support or a nitrifying bacteria house made of talcum powder can be flexibly added. The bacteria house is loose and porous, and the bacterial culture effect is very ideal, which can help improve the water quality environment of the sea area where it is deployed.

[0067] It has been verified that the combinable chevaux-style artificial fish reef of the present invention can reasonably expand the surface area for the growth of attached organisms on the basis of traditional reef piles, can effectively and reasonably cater to the attachment activities of reef organisms, and at the same time, the hollowed-out area at the bottom can often provide a good shelter for some fish larvae, play a role in gathering fish schools, and has potential economic value; the combinable chevaux-style artificial fish reef can not only provide a good environment for attached organisms, but also has a beautiful shape and saves most of the stones. The conical structure is similar to the form of rope breeding (attached and growing organisms can grow rapidly on rough nylon ropes, waste plastic barrels and broken large pieces of sand and gravel), and optimizes their living environment under a reasonable breeding space, which is conducive to increasing the attachment opportunities of hook shell larvae and increasing the effective attachment base area, while also reducing the impact of ocean currents; the expansibility is excellent, and it can be extended and stacked to create a new type of fish reef system with linkage and space. In addition, its special structure can not only play a certain role in wave resistance, but also the semi-enclosed space between the front and rear plates in the chevaux-style artificial fish reef shields the influence of external water flow on the internal space to a certain extent, and at the same time can guide the flow direction in the space to help the growth of attached organisms, and has great application prospects.

[0068] Although specific embodiments of the present invention are described above, those skilled in the art should understand that these are merely examples and that various changes or modifications may be made to these embodiments without violating the principles and essence of the present invention.
