Description

The invention relates to agricultural machinery, in particular, can be used to clean ponds from blue-green algae. Known devices for cleaning water from blue-green algae / 1, 2 /. The design of the devices used mechanical means of destruction of algae and their disposal. The devices are complex in design, energy intensive and complex in the structure of the technological process.

To combat blue-green algae, in addition to mechanical and chemical methods, the most modern, simpler biological method for cleaning water bodies is also used, based on the biological decomposition of organic elements in order to deprive blue-green algae of growth nutrients.

Disadvantages of known devices

1. The complexity of the design of mechanical means to combat algae.

2. Designs of known devices do not provide for the possibility of using biological products for the destruction of blue-green algae.

According to the set of common essential features, a device for applying a sorbent in a stream of water is taken as a prototype / 3 /.

The objective of the invention is to increase the efficiency of the use of biological products in the purification of reservoirs from blue-green algae.

The task is carried out by introducing biological products into the water column using a device on the rod of which racks are fixed, having holes in height for attaching spray nozzles, made in the form of a circle sector with holes around its perimeter, and installed with the possibility of changing the position in the vertical plane by rearranging them moreover, the rod of circular cross section, hollow, at the same time serves as a pipeline for supplying a solution of biological product to the sawing nozzles. The bar is assembled from separate sections with the possibility of translating it into a transport position.

In a particular case, in the inventive device, the following of the known biological products can be used as a biological product: to reduce nutrient pollution by using algolization of water bodies with the introduced chlorella Chlorella vulgaris IGF N C-III / 4 / stamp, which is introduced into the water body in the form of a suspension / 5 / ;

through the use of the biological product MikrozimPond Trit to prevent and eliminate favorable conditions for the development of blue-green algae-cyanobacteria / 6 /.

The technical result - the effectiveness of the use of biological products is increased. The technical result is achieved due to the design of the device, which allows you to add biological products of liquid consistency or in solid / powder / condition without direct contact of maintenance personnel with drugs, which corresponds to the conditions of safe operation. In addition, the working solution can be simultaneously applied to the surface of the reservoir and to the depth of algae, while increasing the area of algae treatment with biological products and accelerating the process of cleansing water bodies. The shape of the spray nozzles in the form of a circle sector with holes along its perimeter allows you to increase the processing area of one spray nozzle and reduce the likelihood of clogging with water impurities. The design of the device will make it possible to install it on watercraft and work offline.

In FIG. 1 and FIG. 2 schematically shows a device for cleaning ponds from blue-green algae.

The device comprises a frame 1, on which a container for mortar 2 with a neck 3 is installed, a pump 4 with a drive from a gas motor (not shown in the diagram), a container for a biological product 5 with a dispenser, a rod 6 with racks 7 for attaching spray nozzles 8, pipelines with taps K ₁ , K ₂ , K ₃ , K ₄ , intake pipe 9 with a filter 12 and a discharge pipe 10, a water mixer 11.

The device operates as follows.

To clean the ponds from blue-green algae, the device is mounted on a floating device and fixed in such a way that the upper spray nozzle is located at the level of the surface of the pond. Rod 6 is put into working condition. The intake pipe 9 with the filter 12 is lowered into the water. The gasoline motor of pump 4 is started and water is pumped into the tank for solution 2 to the required level, while the taps K ₁ and K ₂ are opened, the taps K ₃ and K ₄ remain in the closed position. Filling the tank for solution 2 with water, the taps K ₁ and K ₂ block. A biological product of liquid consistency from a container for a biological product 5 is poured into a container 2 in a certain norm, and a biological product in a powder state is introduced into a container 2 through the neck 3 and is closed. The K ₂ and K ₃ valves are opened, the liquid is mixed, ensuring the solubility of the biological product using a water mixer 11. Having a homogeneous state of the solution, the K ₃ valve is closed, and the K ₄ valve is opened and the solution is sprayed with nozzles 8 simultaneously on the surface of the reservoir and to the depth of the algae. After the technological process, the rod 6 is transferred to the transport position.
