Description

The invention relates to the fishing industry, namely, devices for the extraction of algae, and is an improvement of the device according to the authors. St. No. 1191045.

From the main auth. St. No. 1191045, a device for feeding algae is known, consisting of a series of mesh catching chambers in the form of diffusers, on which jet pumps are installed, connected to the fishing vessel by means of pipelines and flexible hoses, one ends of pipelines are hingedly attached to the vessel , and catching chambers are hingedly connected with the latter and equipped with cutting devices, each cutting device is hinged and consists of fixed knives and cutters driven in rotation and equipped with a copier.

The aim of the invention is to improve the reliability of work on stony soils with difficult bottom relief when interacting with underwater obstacles, as well as reducing the build-up of algae on the grid of catching chambers and thereby increasing its productivity.

In Fig.1 schematically shows the proposed device, side view; figure 2 is the same, front view; on fig.Z - cutting device, side view; figure 4 is the same, top view.

The device for the extraction of algae mounted on the fishing vessel 1.

The device (Figures 1 and 2) contains pipelines 2, one ends of which are hingedly attached to the hull of the vessel 1, while others are connected to the crosshead 3, and the mesh catch chambers 4, made in the form of diffusers, are narrowed at x which are installed jet pumps 5. Each pump 5 is connected to the corresponding pipeline 2 by means of a hose 6.

Cutting devices 7 are hinged on the catch chambers 4 on hinges. Each cutting device 7 (FIGS. 3 and 4) includes a body 8 with copiers 9, fixed knives 10 and knives consisting of a disc 11 made of elastic material, and fixed along its circumference hard blades 12, while the knives have autonomous drives, for example, hydraulic (not shown) to impart rotational motion to them. Hard blades 12 are advisable to remove.

In addition, on the outer side of the walls of the catch chambers 4, vibrators 13 can be installed, for example, of an unbalance type. The pipelines 2 together with the cross beam 3 are a rigid structure associated with the winch 14 installed on the vessel 1.

The device works as follows.

At the beginning of work at the low speed of the ship 1, the piping 2 with catching chambers 4 suspended from the hinges to the traverse 3 is brought under water to the working depth by means of a winch 14. At the same time, the immersion depth 4 M and move back a little, turning on the joints. After that, autonomous drives of cutting devices of 7, which move together with catching chambers 4 along the bottom and cut off the algae with knives 10 and rotating elastic disks 11 with hard blades 12, run. When moving, the cutting devices 7 using copiers 9 they copy slight changes in the bottom relief when hitting stones and underwater obstacles, elastic knives 11 with rigid blades 12 are folded back, 5 thereby protecting the rigid blades from deformation and damage. The cut off algae are supplied with flowing water to the constricting parts of the catching chambers 4, where they are sucked in by the pumps 5 and fed through the hoses 6 and the pipelines 2 to the vessel 1.

During operation, the vibrators 13 oscillate the mesh of the catch chambers 4, as a result of which the cut off algae do not settle on them.

When working on stony soils with difficult bottom relief, the device reliability is significantly increased by eliminating the breakage of hard blades 12 when meeting with underwater obstacles, as the discs 11 bend around the latter and retracted from the danger zone. Improving reliability also contributes to the performance of the blades 12 removable, since the outgoing blade 12 can be quickly and easily replaced with new ones.

Installation on the pickup chambers 4 5 of vibrators 13 eliminates sticking of cut algae on their grids, they are completely fed to vessel 1, which leads to an increase in the productivity of the device. Productivity can be increased by 25-30%, and the durability of the cutting device can be increased by 1.5-2 times.
