Description

Fishing trawler aft trawl.

The utility model relates to the field of shipbuilding, and more specifically to the designs of medium-sized fishing trawlers-forage trawl seiners, and can be used in the design, reconstruction and construction of vessels of the fishing industry fleet.

Known fishing trawler-fodder trawl factory, containing a hull with a feed slip and a middle superstructure, as well as located on the aft end one above the other decks of the upper and lower workshops for processing fishing objects and an additional deck located above the deck of the upper workshop with a platform for receiving the trawl with the upper end of the feed slip and performed with a recess formed from side to side and located between the deck of the upper workshop and the additional deck transverse th middle superstructure and leaving the top open portion of the upper deck of the shop in which said harvesting mechanism has (see. № RF Patent 2016811, MCL V63V35 / 20 zayavl.29.04.91, opubl.30.07.94 analog). The known invention has good performance due to a decrease in the center of gravity of the vessel. This is explained by the fact that fishing gears, which have a huge mass, are placed not on the topmost additional deck, but on the deck of the upper workshop inside an open recess space. However, it also has disadvantages. In view of this design of the additional deck (continuous from starboard to starboard), the decks of the lower and upper workshops are not used effectively.

Placing fishing gear in one place - in the open space of the recess - also significantly reduces the operational qualities of the vessel. This is due to the fact that trap and trawl rigging in recession, their breaks are possible. When working in the extreme north, an open recess with winches placed in it is an accumulation box for icing, which significantly reduces the stability and, therefore, the operational qualities of the vessel.

the latter an additional deck with a platform for receiving the trawl, conjugated with the upper end of the aft slipway and made with a recess formed by a transverse bulkhead located between the deck of the workshop and the additional deck, and the aft bulkhead of the middle superstructure, movably connected in the recess area with the deck of the middle superstructure tank, and also fishing gears, the fan winches of which are located in the arched space of the aft slipway, and the rest on the additional deck are closer to the recess (see Certificate of Useful Fashion Russian Federation No. 15566, MO В63В35 / 20, declared on 04/14/2000, publ. 27/10/2000 in bulletin No. 30. Author VV Aglodin - prototype).

The disadvantages of the known trawler is the deterioration of the operational seaworthiness (stability) of the trawler and the insufficiently high efficiency of its operation. This is due to the increase in the center of gravity of the vessel due to the fact that a very significant mass of fishing equipment is located on the additional deck of the trawler. Consequently, the operational seaworthiness of the trawler is low, which reduces the economic efficiency of the operation of the vessel. Thus, as shown by the analysis of information about the current level of technology in this field, the known fishing trawlers of fodder trawling do not provide high performance.

Declared as a utility model, the feed trawler trawler allows to achieve a new technical result - increasing the economic efficiency of the vessel by improving performance and improving safety. The following set of essential features characterizes the essence of the proposed utility model and contributes to the achievement of a technical result. A fishery trawler fishing trawler, comprising a hull with a fodder slip, made like a viaduct with the formation of an arched space, and a middle superstructure, located at the aft end of the hull of the deck of the workshop for processing objects and placed above the deck of the workshop an additional deck with a platform for receiving trawl, paired with the upper the end of the stern slip and performed with the recess formed by the transverse bulkhead located between the workshop deck and the additional deck and the stern bulkhead of the middle superstructure oyki, and connected to the deck of the tank of the middle superstructure as well as fishing mechanisms, characterized in that the fishing mechanisms are located on the deck of the workshop in the recess space, the additional deck is fixedly connected to the deck of the tank of the middle superstructure and is made in the recess area with at least one window.

Thus, as shown by the analysis of information about the current level of technology in this field and the essence of the proposed utility model, the latter meets the patentability criterion of “novelty.

The proposed fishing trawler aft trawl is illustrated using the drawings, where:

In FIG. 1 shows a trawler, a longitudinal section; Figure 2 is the same, a top view.

The fishing trawler of the aft trawl contains a hull (see Fig. 1) with a fodder slip2 (see Fig. 1.2), made of a viaduct type with the formation of an arch space 3, and a middle superstructure4, located at the aft end of the hull deck5 workshop for processing fishing objects with a freezer compartment. Above the deck of the workshop there is an additional deck with platform 9 (see Fig. 2) with side rails (not shown in the devil) for receiving the trawl. Deck 3 is associated with the upper end of the feed slip2 and is made with a recess, limited in the bow by the bulkhead 11 (see Fig. 1,2), which separates the living and office space 2 of the superstructure 4, and in the stern by the bulkhead 13, which separates the workshop. The deck in the recess area motionlessly connected to the deck 4 of the superstructure tank 4 and from below supported by pillers 15.

At site 9 of the additional deck З there is a cover 6 of the fish bunker 7 (see figure 1) installed in the workshop.

Fishing gears, for example, a trawl winch 18 with cable-exhaust (not shown) and fan drums 19, are installed on the West Coast in the Recession area. In this case, the war 20 drums 19 pass outside the working area under the jammer 9 of deck 8. To pass the cables 21 of the winch cable and exhaust drums 18 to the trawl deck 9 of the additional deck 8, for the purpose of fishing operations, at least one window is cut out in the latter, for example, four windows, two of them 22 for cable drum cables, two others23 for guine drum cables . For the passage of cables of cable-exhaust drums along platform 9 of deck 8 and slip2, horizontal rollers 24 and 25 are installed on platform 8. The additional deck itself was made with additional recesses26.27 (see figure 2) located between the deck of the workshop and deck 8 on the starboard and port side of the vessel.

In the stern of the vessel there is a trawl bridge 28 with suspended trawl warriors

blocks29 and rollers 30 for guiding the warp20 to the warp drums 9.

For storage of processed and frozen fish on board

refrigerated hold 31.

Fishing trawler operates as follows.

Raising the trawl begins with a selection of warriors 20 with the help of warmer drums 19

winches 18. After sampling warriors 20 with cable exhaust drums

carry out the winding of the cables of the trawl on the cable reels of the winch 18. Then along

slip2 is lifted onto the platform 9 of the deck 8 the trawl bag with the catch, and through the cover 16

the fish flows by gravity into the bunker 7 of the fish workshop 6 for processing. Thus,

all operations to lower and raise the trawl are carried out according to the existing fishing

scheme.

Transportation of raw materials in workshops, freezing department and finished products in

hold 3 and waste production is carried out in a known manner.

The advantages of the proposed utility model in comparison with the prototype

are as follows.

All fishing gears, namely the trawl winch 18, are not located on

upper additional deck 8, and on the lower deck 5 workshop. It is essential

reduces the center of gravity of the vessel, which increases the stability of the vessel, and therefore, its

seaworthy performance is quite high.

Fixed connection of additional deck 8 in the area of Recess to deck 4

the tank can significantly increase the strength of the additional deck8, which

significantly affects the performance of the vessel and significantly improves

safety measures on the ship. In addition, all fishing mechanisms are located in

enclosed space, which also significantly improves performance

of the vessel, namely: trawling of the trawl and trawl equipment during recession is excluded, their

ruptures, significantly reduced flooding and icing fishing

mechanisms.

Performing an additional deck with at least one window makes

possible passage of cables of cable-exhaust drums of a trawl winch 18 along

deck 9 deck8, thereby providing the necessary fishing operations for

lowering and raising the trawl.
