Description

The utility model relates to the protection of the aquatic environment, namely: increasing the potential for self-purification of the sea and ensuring the reproduction of marine organisms.

Artificial reef modules are known to reduce the negative impact of environmental pollution on marine ecosystems and increase the breeding sites of marine organisms, made in the form of breakwaters (see www.reefboll.org) However, these models of artificial reefs are mainly intended to protect coastlines and perform more technical functions.

Famous domestic reef structures made in the form of collectors with ruffs, gravity anchors, floats, (see, for example, Sokolsky A.F., Popova N.V., Kolmykov E.V., Kurapov A.A. Bioecological fundamentals and practical the results of the development of a system for protecting the biological diversity of the Caspian Sea from pollution. Astrakhan. 2005. p. 26-36.) The main significant drawback of this technical solution chosen by the applicant as a prototype is:

- poor storm resistance of the reef system;

- low vitality of the model;

The tasks are solved in the presented utility model by performing it in the form of a closed loop, consisting of biostations-anchors interconnected by trunk cables, on which filter reef elements in the form of nitrofiber bundles are placed, and the biostation-anchor itself is made of a cylindrical metal frame consisting of several tiers mounted on a concrete base with rectangular through holes

for the penetration of marine organisms into the inner volume of the ring. In the upper part of the metal frame there are ears for attaching the main cable. In the internal volume of the frame are located accounting areas. These sites are designed to control the formation of a biocenosis and its introduction to other similar biostations. Pads are easy to install and remove

The above set of essential features that implement the task posed by the utility model is not known either from the patent technical literature or from the practice of exploiting artificial reefs, which meets the “novelty” criterion for the utility model. The same new set of essential features can be implemented repeatedly and completely solve the problem posed by the utility model, which meets the criterion of “industrial applicability”.

The essence of the utility model is illustrated by the drawing, where:

- figure 1 - shows a reef module.

- figure 2 - shows a General view of the design of the biostation anchor

The reef module forms a closed loop, through biostations-anchors connected along the perimeter by trunk cables 1 (Fig. 1), on which the pelagic part of the module is hung, represented by reef elements made of nitrofiber bundles 2 (Fig. 1) and propylene fabric.

Reef biostation-anchor (figure 2) consists of a concrete base 1 (figure 2), representing a ring, in the wall of which there are two through windows of a rectangular shape 2 (figure 2.). A metal frame 3 (Fig.2.), Consisting of several tiers, is rigidly fixed to the concrete base. On each tier can be placed accounting area 4 (Fig.2.). In the upper part of the metal frame there are ears 5 (Fig.2.) For attaching the main cable.

The work of the reef module is as follows.

The module is installed on the bottom surface in the depth range of 10-30 m. The succession (formation process) of the communities of organisms on the module is distributed in the following order. At biostations-anchors are formed

benthic (bottom) communities and periphyton (fouling organisms). Communities of microorganisms are formed on reef elements in the form of bundles of propylene fabric that actively break down pollutants, including petroleum hydrocarbons. In the internal "yard" of the module, conditions are created for the accumulation of detritus (organic matter that settles to the bottom (the remains of algae, animals, fish)) and the formation of benthic infauna communities (organisms living in the soil), most of which are valuable food for fish. A zone of increased productivity is also formed around the reef module from its peripheral side.

The advantages of the proposed utility model over the well-known models of artificial reefs are as follows:

- reliable shtromoustoychivost;

- simplicity and structural strength;

- the reef module of the contour type creates an area of increased productivity of benthos, which is formed in its inner "yard".

- affects both the pelagic (water column) and the bottom water area.
