Abstract

A device for the extraction of aquatic organisms, containing a craft with a propulsion device and a loading platform, a net fishing gear with floats and cargoes, a device for collecting cysts, characterized in that the craft is made in the form of a trimaran on inflatable pontoons with a propeller as a propulsion device, and a device for collecting the cyst includes a pump, a suction pipe with a submersible intake, and a discharge pipe, the output of which is movable relative to the container placed on the cargo platform of the craft.

Description

DEVICE FOR RECEIVING WATER1 ORGANISMS.

The utility model relates to the field of aquaculture, and more specifically, to devices for collecting fodder mass, in particular cysts} of crustacean crayfish c ri e / wtQSc / “D- development and reproduction of hydrobionts.

Known devices for the extraction of algae, including mesh trays. a porter tape with alternating rows of cutting devices reinforced across it, a device for collecting the extracted products and a transport device (see, for example, ASSSSR 1 725636 according to class AOIK 75/00 for 77g.

The disadvantages of the described device should include low productivity and efficiency due to the small geometrical dimensions of the intake device.

The closest to the proposed technical solution in terms of technical nature and the effect achieved is a device for collecting t iktni c cysts (fha containing a watercraft with a water propeller as a mover and a loading platform, a net fishing gear with floats and loads, a device for collecting cysts in the form of a conveyor tapes with alternating rows of partitions strengthened across it (see, for example, Prospect / L /

The disadvantages of the described device include a significant amount of garbage and impurities in the collection, due to the design of the collection device and the presence of a watercraft propeller for mining cysts in shallow waters.

The objective of the utility model is to eliminate these shortcomings and improve the quality of the collection.

LM A 01 to 61/00 A 01 K 75/00 The problem is solved due to the fact that in the known device for the extraction of aquatic organisms, containing a watercraft with a mover and a loading platform, a net fishing gear with a float and loads, a device for collecting cysts, of the proposed utility model, the craft is made in the form of a trimaran on inflatable pontoons with a propeller as a propulsion device, and the device for collecting cysts includes a pump, a suction pipe with an immersion intake, and a discharge pipe, the output of which is possible the ability to move relative to containers placed on the cargo platform of the craft. Achieving the task is really possible, because the implementation of the watercraft in the form of a trimaran on inflatable pontoons with a propeller as a propulsion device ensures the movement of the watercraft in shallow water without mixing and soaking outboard water with bottom impurities. In addition, the implementation of the device for collecting cysts in the form of a pump with a submersible intake allows collecting cysts not from the surface of the reservoir, where the percentage of shells and non-viable cysts with a lower specific gravity is large, but from a shallow depth, which increases the quality of collection. In the drawings, the proposed device is schematically presented, in which Fig. 1 shows a general view of the device in the process of packing extracted cysts, in Fig. 2 is a top view, and in Fig. 3, an immersion fence during the collection process and the percentage of conditioned cysts in the production layer. The device comprises a trimaran vehicle on inflatable pontoons I made of layered rubberized fabric and connected by a loading platform 2, on which a propeller 3 and steering device 4 are used as a propulsion device. A centrifugal pump 5 for collecting cysts is mounted on the loading platform 2 compressor 6 for pumping pontoons I and. pumping a tubular float 7 of a net fishing gear containing a plankton net 8 made of Jfe 38 gas and a hose 9. The pump 5 is equipped with a suction pipe 10 with a perforated intake II and a discharge pipe 12, the flexible end of which can be moved relative to those installed on the cargo platform 2 elvmocTefl for packing, generally made in the form of jute bags 13 with a width to height ratio of 1/3, mounted vertically in supports 14. In addition, on the loading platform 2 there are packaged jute bags 15, devices vymotyvaniya for fishing gear 16, for example, Babin and windlass (not shown), cysts distribution in the water in the water obmotannom portion shown in FIG. 3 and determines the immersion depth of the intake II. The device operates as follows. After detecting a cyst stain in a pond and a bait boat; trimaran orientations using a motor boat (not shown in the drawing), the stub is washed with a fishing gear while pumping a tubular float 7 with a compressor. 7. After fishing and freezing of the free end of the fishing gear onto the trimaran, the fishing gear is pulled by evacuation of air from float 7 and sampling of fishing gear to baboons 16. When testing the device under natural conditions, a spot of cysts with a diameter of 150 meters was pulled down to a diameter of 5 meters with a layer height of industrial failure up to 70 centimeters. Then, on a loading platform 2, jute bags 13 are unfastened in supports 14, the intake II is immersed to the required depth and the pump 5 is turned on. The jute bags 13 are filled one by one with pulp containing cysts 17. At the same time, water passing through the fabric of the bags flows overboard, and the cysts 17 remain in the bags 13. By sequential filling of the bags 13 with the pulp it is possible to pack them completely with the cysts 17, after which the packaged bags 15 are tied, the freed stands 14 are transferred to an empty seat of the loading platform 2 and new empty bags are unfastened in them 13, the filling of which is carried out in the above sequence. After collecting the entire spot of cysts 17 and packing transport shafts, a fishing gear is selected on the loading platform 2 and the trimaran is sent to the shore to unload the extracted cysts into storage facilities for subsequent processing.
