Abstract

PURPOSE:To reduce projecting parts and facilitate the loading/unloading of fish by enabling a cover body to travel between a part directly under the opening part of a deck and a lower housing position on a side, providing a means of rotatably receiving a hinge on the end of said cover body, and pulling said cover body obliquely upward in a closing direction. CONSTITUTION:As a jigger cylinder 13 is contracted, a cover body 3 is pulled obliquely upward and moved forward. When the cover body 3 arrives at right under an opening part 1A, the hinge 7 on its end is received by a hinge receiver 9 on a hull side, restricting the forward movement of the cover body 3. As the rear end of the cover body 3 is continuously hung up by the jigger cylinder 13, the cover body 3 is rotated centering around the binge 7 and arrives at a closing position. And, when cylinder 13 is contarily extended, the cover body 3 is housed on the upper part of a fish pond 2. Accordingly, the loading/ unloading of fish can be easily carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) - The present invention relates to an improvement of a fish hatch cover provided at the opening of a fishpond such as a trawler.

(Prior Art) A fish hatch cover as shown in FIG. 4, for example, is installed in a fish pond into which fish caught by a trawler or the like is loaded. That is, a fish pond 2 formed in the hull is opened to the upper deck 1, and a fish hatch cover 2 is attached to the upper deck 1 so as to be freely rotatable inward.
0 to open and close this opening IA. The caught fish are thrown into the fish pond 2 from a fishing net 21 lifted above the opening IA by a winch.

(Problem to be Solved by the Invention) However, in this case, it is necessary to secure an opening space for the fish hatch cover 20 in the fish pond 2, and the back side of the open fish hatch cover 20 becomes a dead space. Therefore, there was a problem that loading efficiency into the fish pond 2 was poor and it was difficult to confirm the amount of fish to be planted.

Additionally, a foldable fish hatch cover 22 as shown in tIS 5 is known as a solution to these difficulties, but in this case, the fishing net 21 cannot be operated because it is stored in an upright position on the upper deck 1. There was a problem that it was easy to interfere with the

SUMMARY OF THE INVENTION An object of the present invention is to provide a fishhatch cover that has few protrusions into the inside of the fishpond or onto the deck, in order to solve the above-mentioned problems in the fishhatch cover that opens and closes the fishpond.

(Means for Solving the Problems) The present invention provides a fishhatch cover that is installed in a fishpond opening formed in a deck, in which the cover body is placed at a storage position directly below the opening and at a lower storage position on the side of the opening. A hinge is protruded from the tip of the cover body, and the axis of rotation is in the transverse direction.As soon as the cover body reaches just below the opening, it receives this hinge and guides the vehicle forward. A hinge receiver that rotatably supports the regulating hinge is fixed to the hull near the opening, and a means for pulling the cover body diagonally upward in the closing direction is provided.

(Operation) When the towing means pulls the cover body in the storage position diagonally upward in the closing direction, the cover body runs along the slope toward the opening, and when it reaches just below the opening, the hinge at the tip connects with the hinge on the hull side. When received by the receiver, the cover body stops moving forward and rotates upward from the rear end around the hinge to close the opening.

Furthermore, when the traction means is released, the cover main body in the closed position rotates its rear end downward around the hinge due to its own weight, and then travels along the slope to reach the storage position.

(Example) Embodiments of the present invention are shown in FIGS. 1 to 3.

In Figure 1, 1 is the upper deck, 2 is the fishpond,
3 is the cover body of the fish hatch cover. The cover body 3 is mounted on a ramp 5 via 2M wheels 4 provided on both sides.
It is placed so that it can run on top of it. As shown in Fig. 2, the ramps 5 are provided facing each other along the wall surface 6 that defines the sides of the fishpond 2, and are set from just below the opening IA of the upper deck 1 to lower than this on the sides. The cover body 3 reaches its storage position. A hinge 7 whose rotation center is in the transverse direction is fixed to the tip of the cover body 3 via a bracket 8. Further, when the cover main body 3 moves directly below the opening IA, a hinge receiver 9 that restricts the forward movement of the hinge 7 and receives it while freely rotating is fixed opposite to the hinge 7 directly under the upper deck 1 in front of the cover body 3. will be established.

One end of a wire 11 driven by a jib-silling 13 as a traction means is locked on the rear side surface of the cover body 3.
Locked via 0. This wire 11 is latched to the cover body 3 from diagonally above via a sheave 12 that is freely rotatably attached directly below the opening IA of the upper deck 1 above the ramp 5, and the other end is attached to the cover main body 3 As shown in the figure, after passing through the sheep 14 connected to the jib-silling 13 provided on the lower side of the front upper deck 1, the cover main body 3 is sandwiched and passed through the sheep 12 on the opposite side. Both locks are locked at 10. Further, one end of a wire 15 extending in the opposite direction to the wire 11 is also locked to the lock 10. The wire 15 is passed through a sheave 116 attached to the rear wall of the fish bong 1/2, passes through a sheave 17 connected to the cigar cylinder 13, and then passes through a sheave 16 on the opposite side across the cover body 3. Then, the same locking point 10 is reached on the opposite side. In addition, these rope beams cost 1 shilling 1
3, the wire 11 is pulled while the wire 15 is sent out, and the wire 11 is sent out while the wire 15 is pulled due to the expansion. Reference numeral 18 denotes a sheave attached to key points on the ship's hull to guide the wires 11 and 15.

Next, the effect will be explained.

When loading fish, the cover body 3 is stored under the upper deck 1 on the side of the opening IA, as shown by the chain line in FIG. As a result, there is almost no dead space within the fish pond 2, and a sufficient amount of fish can be loaded. Furthermore, since the inside of the fish pond 2 can be seen from the upper deck 1, the loaded fish can be easily weighed. Furthermore, there is no fear that the cover main body 3 stored under the upper deck 1 will interfere with the fishing net being worked.

To close the cover body 3 from the storage position, the knob-cylinder 3 is retracted and the cover body 3 is pulled diagonally upward via the wire 11, and the wheels 4 are transferred on the slope 5 to close the cover body 3. runs forward. Note that since the wire 15 is sent out when the hemlock cylinder 3 contracts, there is no fear that the wire 15 will prevent the cover body 3 from moving.

When the cover body 3 reaches just below the opening IA, the hinge 7 at the tip is received by the hinge receiver 9 on the hull side, and the cover body 3
is restricted from moving forward. Then, the hemlock cylinder 3, which continues to contract, lifts up the rear end of the cover body 3 via the wire 11, so that the cover body 3 rotates around the hinge 7 and reaches the closed position shown by the solid line in FIG. .

On the other hand, in order to open the cover body 3 which is in the closed position, when the cigar cylinder ≠ is extended, the wire 11 is first loosened, the cover body 3 rotates downward around the hinge 7 under its own weight, and the wheels 4 move onto the ramp 5. Contact.

When the hemlock cylinder 3 is further extended, the cover main body 3 travels downward along the slope 5 due to its own weight and reaches the storage position. Note that the running speed at this time is determined by the speed of the wire 11 that is sent out as the cigar cylinder 13 expands.

(Effects of the Invention) As described above, the fishhatch cover of the present invention is configured so that the cover body can run between directly below the opening of the deck and a storage position lower than this on the side, and is provided at the tip of the cover body. In addition to providing a hinge receiver on the hull side near the opening to freely receive the hinge that has been opened, a means for towing the cover body diagonally upward in the closing direction is provided. Once it reaches the bottom of the deck, the hinge is received by the hinge receiver, and the cover body rotates upward from the rear end around the hinge, closing the opening in the deck.

Therefore, during the work of loading and unloading fish, the cover main body is stored in the storage position above the fishpond behind the opening, and not only does it not interfere with the work at all, but also does not create any dead space within the fishpond. Additionally, since the view is not obstructed when looking into the fish pond from the deck, it is easy to weigh loaded fish. Furthermore, since the opening/closing operation of the cover body by traveling and rotating around the hinge is all driven by the traction means, there is no need for a large-scale drive device for opening/closing, and the space and cost required for the drive device are reduced. It's done.

Therefore, according to the present invention, a substantial increase in the capacity of the fishpond and an increase in the efficiency of the fish loading and unloading operation can be realized at a relatively low cost.
