Description

[Detailed description of the invention] [Industrial field of application] This invention is used for cultivating seaweed, fish, pearls, etc. under the sea, and is used for cultivating seaweed, fish, pearls, etc. In addition, the position after driving into the ground is such that each hanging piece exhibits a radially open state like the arms of an anchor, and the presence of ridges on the hanging piece makes it possible to This increases the sinking resistance.

[Conventional technology] Conventionally, when building this type of aquaculture support, the depth to which it would be driven into the ground was determined entirely by intuition.
If the ground is soft, such as sandy soil, it may be difficult to determine the depth at which it will be driven into the ground, leading to over-driving. Furthermore, the driven state will not be fixed and will be unstable, causing the support to sink or fall. There may be times when you get out of the way and then go up again.

For this reason, some devices have been devised to stabilize the front support by wrapping a rope around the support or attaching protrusions, but these methods require time and effort to wrap the rope or attach protrusions. Moreover, when storing the prop, the rope and protrusions were bulky and difficult to handle.

Therefore, as the first prior art, the applicant first proposed
According to No. 60-7810, the lower part of the flat plate made of a flexible material has a width equal to the length that goes around the lower outer peripheral surface of the support and a vertical width equal to the required length, and can be opened at any angle by cutting the lower part of the flat plate made of a flexible material in the vertical direction. The present application has been filed for a position fixing device in which a large number of hanging pieces are formed, and a hook piece and an engagement hole for locking the hook piece are provided at the upper end of the flat plate. Also, as a second prior art,
According to No. 60-44264, the central part of a flat plate similar to that of the above-mentioned application is cut in the longitudinal direction to form a large number of bendable band-like pieces, and the upper and lower ends of the flat plate are provided with hook pieces and locks for locking the hook pieces, respectively. An application was filed for a position fixing device with a matching hole. These position fixing devices are installed by going around the outer circumferential surface of the tip of the column and locking the hook into the engagement hole, and when the top of the column is tapped and buried in the ground, it will not sag. The pieces are made to open at an angle, and the band-like pieces are bent outward.

On the other hand, as a third prior art, the "prop removal prevention device" of Utility Model Application Publication No. 54-174593 includes a fastening body that can be detachably attached to the outer periphery of an aquaculture support, and a fastening body that is pivotably attached to the fastening body and extends upwardly. It consists of a large number of wing pieces with expanding parts, and is inserted into the earth and sand of the seabed, etc., with a fastening body attached to a predetermined position on the outer periphery of the support. Then, the presence of the large number of wing pieces increases the resistance in the sand and sand, and especially when the support acts in the direction of pulling out, the large number of wing pieces pivotally connected to the fastening body expands, resulting in even greater resistance. As a result, the stability of the support column is increased and the support column is prevented from slipping out. Furthermore, as a fourth prior art, the "Strut for aquaculture of seaweed, etc." disclosed in Utility Model Application Publication No. 54-174592 consists of a strip plate that can be tightened around the outer periphery of the column and a number of protruding pieces protruding from the outside of the strip plate. Disclosed is a device in which a prevention device is detachably attached to a lower part. This is to prevent the support from falling off and from sinking using the protrusion.

[Problems to be solved by the invention] However, in the first and second prior art, since each hanging piece or band-like piece of the position fixing device is flat as a whole, the rigidity is low when it plunges into the ground. There is a risk that it will not spread properly due to
There was a problem with maintaining the wide-angle lens when it was buried underground.

Furthermore, in the third conventional technique, although it is recognized that the pull-out preventive device is difficult to pull out upwardly of the pillar that is stuck in the earth and sand, the many wing pieces that are pivoted to the fastening body due to the piercing of the pillar are stuck in the earth and sand. It is pressed against the outer periphery of the support column and held in a close contact state. For this reason, there was a problem in that there was little resistance to sinking, and it was impossible to prevent the columns from sinking.

Further, in the fourth prior art, there was a problem in that the protrusion projecting outward from the strip became an obstacle when driving into the ground, making it particularly difficult to drive into hard mud-like ground.

[Means for Solving the Problems] Therefore, the purpose of the present invention is to provide a single aquaculture support position fixing device with three advantages: prevention of slippage, prevention of subsidence, and ease of driving into the ground. Therefore, it has a width equal to the length that goes around the lower outer peripheral surface of the aquaculture support and a vertical width equal to the required length, and the lower part of the flat plate made of a flexible material can be cut vertically to freely open. A large number of hanging pieces are formed, and at least one side of each hanging piece is provided with a ridged portion in a transverse manner, and the ridged portion includes an inclined surface tilting backward with respect to the upper part of the hanging piece, and a side end of the inclined surface. and a bent surface that bends from the edge to the hanging piece, and the upper end of the flat plate has a hook piece formed at one end and an engagement hole for locking the hook piece at the other end, and further has a hook piece formed at the other end. A tab piece is extended at the tip of the matching hole, a non-slip part is provided on the upper side of the side of the flat plate on which the ridged part is provided, and each of the hanging pieces is placed downward on the outer periphery of the pillar at a predetermined position,
The lower part of each hanging piece is configured to expand upward by being wound and installed with the ridged part inside.

[Function] Attach the position fixing device to the outer periphery of the pillar with each hanging piece facing down and the ridged part provided on each hanging piece facing inside, and drive it into the ground to tilt the ridged part backward. The sloping surface allows the hanging pieces to be spaced apart from each other so that they do not come into close contact with the support. In particular, since the tips are separated from the outer peripheral surface of the support, each hanging piece smoothly enters the ground while expanding outward radially when it touches the ground. When the prop is driven into a predetermined position, the anchor becomes arm-shaped, and the curved surface of each ridge is supported in a nearly horizontal position underground, increasing sinking resistance. In addition to preventing the column from sinking and making it stable, the arm-shaped hanging pieces also increase the resistance to rising, making it difficult for the column to fall out.

[Example] In the figure, reference numeral 1 denotes a flat plate made of a flexible material having a horizontal width that approximately goes around the lower outer peripheral surface of the aquaculture support support P and a required vertical width, and the lower part of the flat plate 1. Separation lines 2 are provided at equal intervals in the longitudinal direction to form a large number of hanging pieces 3. On one side of each hanging piece 3, a ridged portion 4 is formed transversely and in multiple stages. Each of the ridges 4 is formed by an inclined surface 4a that is inclined rearward with respect to the upper part of the hanging piece 3, and a bent surface 4b that is bent with respect to the hanging piece 3 from the rear end edge of the inclined surface 4a. Further, protrusions 5, 5' are provided on both sides of the upper end of the flat plate 1.
are arranged opposite to each other, one of the protruding pieces 5 is provided with a hook piece 6 on the flat side on which the ridged part 4 is not provided, and the other protruding piece 5' is provided with a hook piece 6 for locking the hook piece 6. A mating hole 7 is formed, and a knob piece 8 is extended from the tip of the mating hole 7. An uneven anti-slip 9 is formed on the side surface of this knob piece 8, and a large number of protrusions are arranged in transverse lines above the ridged portion 4 on the side surface of the upper part of the flat plate 1 where the ridged portion 4 is provided. The anti-slip portion 10 is formed by providing the anti-slip portion 10.

The ridged portion 4 is formed to have a sawtooth cross section, and each hanging piece 3
The tip of the trough 11 is made thin, and the space leading to the trough 11 that forms the boundary with the adjacent ridged part 4 is formed into an arcuate surface so that the rigidity changes almost entirely.
This allows for maximum flexibility.

Next, to explain the use of the position fixing device of the present invention constructed in this way, the position fixing device A is placed in a predetermined position of the part of the support P to be driven into the ground E, with each hanging piece 3 facing down. Then, place each hanging piece 3 with the side provided with the ridged part 4 on the inside, and pull the tab piece 8 to lock the hook piece 6 in the engagement hole 7, thereby attaching the support post P.
Complete the installation for.

The aquaculture support P with the position fixing device attached in this way is placed upright in the sea, and the upper end is hammered into the ground E. When the tip of each hanging piece 3 of the position fixing device A touches the ground, these Each hanging piece 3 has a ridged part 4 with a space between adjacent pieces as shown in FIG.
Since a is at an open angle with respect to the support column, each of them expands outward from the support column P and plunges into the ground as shown by the dashed line in FIG. 5 due to the interaction with the ground upon contact with the ground. As the support P is subsequently driven in, each hanging piece 3 gradually expands radially as shown by the two-dot chain line in the same figure, and enters the ground while being resisted by each ridged part 4. And the pillar P is underground E
When the hanging pieces 3 are driven to a predetermined depth, as shown by solid lines in the figure, each hanging piece 3 opens radially like an arm of an anchor, curves, and is buried in the ground E, and in this buried state. Since the bent surface 4b of each ridged portion 4 is supported in the earth and sand in a substantially horizontal state, the position is restrained, so that the sinking resistance becomes large.

In this way, each of the hanging pieces 3, which are radially spread outward and curved, serves as an arm of an anchor, and at the same time, the bent surface 4b of the ridged part 4
Since it is in a substantially horizontal state, it is possible to increase the sinking resistance of the column P and improve its stability, thereby eliminating sinking and firmly preventing it from tilting or falling out.

In addition, when providing a plurality of ridge-like parts 4, at least one ridge-like part 4 having a rearwardly inclined inclined surface 4a at an angle with respect to the driving direction of the aquaculture support is provided on the side opposite to the aquaculture support. The above effect can also be obtained by providing an appropriate number of other ridges 4 or ridges on the opposite side.

Furthermore, what is shown in FIG. 6 is an embodiment in which a ridged portion 4 is provided only at the tip of each hanging piece 3, and this embodiment is also provided with a large number of ridged portions 4 of the previous embodiment. When used in the same manner as above, the sinking resistance of the support column can be increased, and furthermore, the amount of material used can be reduced compared to the case where a large number of ridged portions 4 are provided.

[Effects of the invention] As described above, the aquaculture support position fixing device of the present invention is designed so that each hanging piece faces down and the ridged part provided on each hanging piece faces the outer peripheral surface of the support. By attaching the support to the ground and using it, when the support is driven into the ground, the distance between each hanging piece is increased, and it is easy to open outward when in contact with the ground, allowing for smooth driving even into relatively hard muddy ground. I can put it in. Furthermore, while buried in the ground, each hanging piece expands radially outward like the arm of an anchor, and the curved surface of the ridge-like part, which is now in a nearly horizontal state, is supported in the earth and sand. . As a result, the sinking resistance of the pillar driven into the ground can be increased, and the rising resistance can also be increased, so that an effect of preventing the pillar from falling out can be obtained, and the position of the pillar can be firmly fixed.
