However, the above-described conventional seaweed control apparatus can more efficiently control the seaweed by elongating the chain for removing the seaweed and sliding it over a wide area on the sea bottom. However, when the chain is lengthened, there is a disadvantage that the chains are entangled with each other when the chain is driven to rotate. For this reason, the diameter of the rotating plate has been increased, or a connecting chain has been provided between the interdigital chains to prevent the chains from being entangled. Thus, there is a problem that the load of the rotational driving force is increased by increasing the size of the rotating plate or adding the connecting chain, and the horsepower of the driving source must be increased.

The present invention has been made in view of the above points, and an object of the present invention is to provide an apparatus for controlling marine algae which solves the drawbacks of the prior art and prevents entanglement of chains. .

[0006]

The apparatus for controlling marine algae of the present invention comprises a driving source attached to a support, a shaft connected to a rotating shaft of the driving source, a hoop and a center extending from the hoop to the center of the hoop. A first hoop portion having a plurality of arms provided radially and connected to the shaft at the center of the hoop, and a plurality of upper ends attached to the first hoop portion at positions away from the center. A swivel chain, a second hoop portion locked at a substantially intermediate portion of the plurality of swivel chains, and a removing member provided at a lower end of the swivel chain, and the swiveling of the swivel chain causes the removing member to have a predetermined position. It is characterized by removing miscellaneous seaweed by sliding on the sea bottom.

Further, the drive source and the shaft and the shaft and the first hoop portion are connected via a bendable universal joint. Also, a driving source attached to the support, a shaft connected to a rotation shaft of the driving source via a first universal joint, and a relay member connected to the shaft at a center via a second universal joint A plurality of upper turning chains having upper ends attached to positions distant from the center of the relay member; an intermediate holder attached to lower ends of the plurality of upper turning chains; A plurality of lower slewing chains having an upper end attached at a position, and a removing member provided at a lower end of the slewing chain. An apparatus for controlling aquatic marine algae, which is characterized by removing the algae. Further, the exterminating member is formed as a ring including a member having a protruding portion.

According to the present invention, the relay member such as the first hoop is driven to rotate by the rotation of the hydraulic motor, and the swivel chain attached to the relay member rotates.
This rotation causes a water flow to scatter the algae and sand. Further, the rotation of the swivel chain drives the intermediate holder such as the second hoop portion to rotate, and the tip removing member of the swivel chain is driven to rotate. Rings and protrusions of the exterminating member of the swivel chain hanging on the sea bottom can rub rocks and the like according to the unevenness of the sea bottom to exterminate miscellaneous seaweed from the roots. The intermediate holding member such as the second hoop member makes it difficult to transmit the impact and unreasonable stress due to the waves and undulations to the support member side, and keeps the stability of a ship or the like on which the member is mounted, thereby ensuring the safety of operation.

Further, when the swivel chain is driven to rotate, it is possible to prevent the swivel chain from gathering and entangled on the rotation center side by providing the intermediate holding member such as the second hoop portion. Can be appropriately diffused and rotated by the centrifugal force of the extermination member without entanglement. Also, even if the removing member of the swivel chain slides on the sea bottom and the relay member and the intermediate holder are rotated by the inclination of the sea bottom having large undulations, the drive source and the shaft and the shaft and the relay member can be bent. Since they are connected via the universal joint, the relay member and the intermediate holder can rotate smoothly.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the apparatus for controlling harmful seaweeds according to the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of a seaweed extermination apparatus, FIG. 2 is a perspective view of an extermination member provided at a tip of a turning chain, and FIG. 3 is a perspective view showing a connection state between the turning chain and a second hoop member. In the figure, reference numeral 1 denotes a support of the weed control device.
Is mounted on a hull (not shown), and can be moved up and down depending on the water depth to be set at an arbitrary position on the sea surface.
Reference numeral 2 denotes a driving source mounted on the support 1 in a suspended manner, and the driving source 2 is constituted by a hydraulic motor or the like. 3
Is a shaft pivotally supported on the rotating shaft of the drive source 2 via a universal joint 8, and 4 is a first hoop portion (relay member). The first hoop portion 4 prevents deformation due to impact or the like. For example, a metal member having a substantially U-shaped cross section is formed in a hoop shape, and a substantially cross-shaped arm 4a is fixed to the hoop-shaped hollow portion.
The shaft 3 is connected to a central portion of a through a universal joint 8. As described above, since the first hoop portion 4 has a hollow hoop shape, the first hoop portion 4 can be rotationally driven without increasing the rotational driving force of the hydraulic motor, and can be moved up and down. The water resistance at the time can be reduced.

Reference numeral 5 denotes a plurality of swivel chains having upper ends attached to the arms 4a of the first hoop portion 4. The swivel chains 5 are constructed by combining metal links as shown in the figure. The two turning chains 5 are attached as a set to the arm 4a, and the interval between the two turning chains 5 in the set is prevented by a connecting member 5a for preventing the interval from expanding or contracting. keeping.
Reference numeral 6 denotes a second hoop section (intermediate holding body). The second hoop section 6 is for controlling the rotation of the turning chain 5 smoothly, and has a hollow section like the first hoop section 4. Forms a substantially cross-shaped arm 6a, and this arm 6a
Approximately the middle portion of the turning chain 5 is locked at the center.
Reference numeral 7 denotes an exterminating member attached to the free lower end of the turning chain 5. The exterminating member 7 is provided with a protruding member 7c for exterminating marine algae while sliding on the sea bottom. For example, two swivel chains 5 in the set
The metal chain having a protruding portion 7b from the lower end of the metal chain 7a is assembled into a chain to form a small loop as shown in the figure, and two arms of the metal chain 7a having one common arm are formed. The rings of the metal chain 7a are connected. Furthermore, on each arm of the two metal chains 7a,
For example, a protruding member 7c having a tooth shape of a clog is mounted.

In the thus constructed apparatus for exterminating marine algae, the support 1 attached to the hull is located on a predetermined sea surface, and the extermination member 7 at the forefront of the apparatus for exterminating the marine algae has a seabed full of marine algae and the like. It is arranged so as to contact the surface with a margin.
In general, the depth of a degraded kelp plant where extermination of algae is carried out is measured with a water depth measuring device, etc., the inclination angle of the support 1 of the algae extermination device is adjusted to determine a fixed position, and the extermination member of the swivel chain 5 Adjust 7 to the depth of the seabed. This water depth is almost 1.5
The most efficient extermination operation is possible when the distance is about m to 5 m. By rotating a hydraulic motor of a drive source 2 attached to the support 1, the first hoop unit 4 is rotationally driven. The rotation of the first hoop section 4 rotates the turning chain 5, and the second hoop section 6 is similarly driven to rotate,
The exterminating member 7 attached to the tip of the turning chain 5 is driven to rotate. This rotational drive is generally rotated at a rotational speed of 15 to 25 times / minute. When the first and second hoop portions 4 and 6 that are rotationally driven are tilted or deflected by the weight of the turning chain 5 or the extermination member 7 or by the influence of sea surface waves, the universal joint 8 causes the drive source 2 to rotate. Is accurately transmitted via the shaft 3. The waves can be handled without any problem with a size of about 1 m.

In general, when the removing member 7 is driven to rotate via the turning chain 5, a large load is initially applied to the drive source 2 by the weight of the projecting member 7c of the removing member 7, and the like.
The swivel chain 5 starts to rotate in an inward direction from the circumferential direction of the arm 4 a of the first hoop section 4, but the marine algae control apparatus of the present invention uses the swivel chain 5 by the second hoop section 6.
Of the swivel chain 5 can be prevented. That is, the first and second hoop portions 4 and 6 can be rotated from the beginning while maintaining the mounting position of the swivel chain 5 in the circumferential direction. When the rotation speed of the swivel chain 5 reaches a predetermined speed, the swivel chain 5 is rotated. Numeral 5 is slightly diffused in the outer peripheral direction by the centrifugal force of the extermination member 7 and is driven to rotate. As described above, the projecting portion 7b and the projecting member 7c of the metal chain 7a of the exterminating member 7 are
By sliding on the sea bottom in a state of being diffused from the sea bottom, it is possible to completely cut off and remove exotic seaweed, such as cybe nihiba, sugamo, and honware, from the roots. Also,
It is also possible to remove calcareous material and sand on the rock surface. Further, the protruding portion 7b of the exterminating member 7 formed with a loop of the metal chain 7a even on a complicated undulating terrain on the seabed.
It is possible to accurately catch and eliminate miscellaneous seaweed by the subtle movement of the projection member 7c.

The protruding portion 7b of the metal chain 7a formed on the ring of the extermination member 7 and the protruding member 7c mounted on the metal chain 7a can slide on the seabed in correspondence with irregularities such as depressions on the seabed. It is possible to catch and exterminate weeds growing between relatively small reefs and undersea trenches. Can move. In addition, the structure in which the exterminating member 7 is attached to the above-described swirl-shaped swivel chain 5 allows the submarine rock surface to slide slightly. In particular, the annular shape of the metal chain 7a is effective for entanglement and removal of relatively large extending weeds, and for cutting dense weeds. Further, the shape of the extermination member 7 can be modified according to the conditions of undulation on the seabed and the ecology of the seagrass on the seabed. For example, an artificial reef chain having a relatively short chain length can be used, and on a relatively uneven surface, two parallel chains are connected by a plurality of connecting members to establish a parallel state. The held flat-plate chain (not shown) is connected to the first and second hoop portions 4,
6, and can be used in the same manner as described above.

Further, the seaweed on an arbitrary sea bottom can be controlled by moving the boat for controlling seaweed. When the marine algae control vessel is located at a predetermined location for marine algae control, anchors are fixed at two rear portions and a front portion of the hull, and the rear 2 algebra is required to move the marine algae control ship to the left and right. In order to move the ship by a hydraulic winch (not shown) and to move the marine algae control ship back and forth, one front part and two rear parts are required.
It can be moved by the original hydraulic winch. Further, when used in a place with a deeper water depth, by combining the shaft 3 and the universal joint 8 in two stages to cope with it, it is possible to exterminate various seaweeds on the deep sea bottom accurately.

In addition to the above-described embodiment, the relay member is not formed in a hoop shape, but, for example, is formed with two to five arms radially like a person, and the center is fixed to the shaft. The swivel chain may be mounted in a balanced manner. The intermediate holder may also be formed in a similar shape, or in the case of an even number of swivel chains, may be combined with a bar material for locking opposing swivel chains. In the above-described embodiment, the turning chain uses one chain from the relay member to the removing member. However, the upper turning chain from the relay member to the intermediate holding member and the lower turning chain from the intermediate holding member to the removing member are used. For example, it is also possible to increase the number of removal members by increasing the number of lower swing chains compared to the upper swing chain. As the extermination member, any other suitable shape that can easily exterminate marine algae can be used. However, if members having protruding portions are connected in a chain shape, the extermination efficiency is remarkably improved.

[0017]

As described above, the apparatus for controlling marine algae according to the present invention is constructed by using the first and second hoops having the hollow structure in the swivel chain as described above, so that the load on the drive source is increased. It can be rotated and driven up and down easily. It is possible to prevent the turning rotation of the swivel chain toward the inner center side at the beginning of rotation, thereby preventing the chain from becoming entangled. In addition, since the extermination member employs a heavy extermination member such as a protruding member as described above, there is an effect that it is possible to accurately slide even on the sea bottom having large undulations and remove various seaweed from the root.

Further, since the tip of the protruding portion of the extermination member has a claw shape, it is possible to exterminate weeds that have grown in a narrow groove on the sea bottom, etc. Can be reliably eliminated, and a wide area of the sea bottom can be efficiently slid by uniformly sliding on a wide area of the sea bottom. Moreover, it has a simple structure, is easy to implement because it can be constructed at a low cost, and has excellent features such as being able to easily move on the sea and exterminate a wide range of weeds. ing.
