Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a storage device used when boats, cruisers, etc. are moored at a port.

[Prior Art] Relatively small vessels with shallow water, such as boats and cruisers, are increasingly being used for recreational purposes in the ocean, and the number of people using them is also increasing.

However, the reality is that these ships are not used all the time throughout the year, and are left unused at ports except for the period from early spring to autumn when they are mainly used. They are not constantly running on the ocean, especially at night or when weather conditions are bad, and are left unused.

Conventionally, the method of storing the above-mentioned ships when not in use is to line up ships A in the harbor along quay b, as shown schematically in Figure 6, and to store each ship a against quay b, etc. A method in which vessels are moored and stored via cables, etc. A method in which vessels a are lifted from the sea to land using a crane c movably installed on quay wall b as shown in Figure 7, and then lined up on land and stored. etc. are adopted.

[Problems that the invention aims to solve] However, although the conventional method described above provides the convenience of being able to use the ship immediately when needed, it means that about half of the ship is submerged in seawater during long periods of berth. Algae and shellfish adhere to the bottom of the ship, etc.
Removal work must be carried out at the time of use, and removing this deposit is a difficult task. In addition, although this method avoids the adhesion of algae and shellfish as in the above method, each time the ship is stored, it must be unloaded and transported to the storage location, and the reverse operation must be performed when using the ship. It is difficult to operate, takes a lot of time, and requires large-scale equipment.Furthermore, if the crane C is used to transport Vessel A, a license is required if the handling weight is 5 tons or more. In addition, as the use of boats and cruisers for leisure purposes on the ocean is becoming more popular, it is desirable to have a short time from storage to use. Due to limitations, there are problems that cannot be dealt with quickly.

Therefore, the present invention is a storage device that eliminates the adhesion of algae and shellfish to the bottom shell of a ship during storage, and also allows ships to be taken in and out easily and quickly without the use of large-scale equipment such as cranes. This is what we are trying to provide.

[Means for Solving the Problems] In order to achieve the above object, the present invention injects air into the inside of a support structure that has a concave cross section and has buoyancy so as to be held in a semi-submerged state. At least two air bags are arranged symmetrically so as to inflate to lift the ship, and the air bags are connected to an air supply source via a valve. Furthermore, a plurality of the support structures can be arranged side by side and connected to each other, and the lower part of the air bag inside the support structure has a rigidity that allows it to stand up when inflated. Either make it stand upright or use reinforcement material.

[Operation] When the vessel to be stored is towed into a support structure, and then compressed air is supplied into at least two left and right air bags to inflate each air bag,
The rigid upright portions of the left and right air bladders are brought into an upright position and the vessel is lifted and held above the sea surface. This prevents algae and shellfish from forming on the bottom shell of the ship over a long period of time. When changing from the stored state to the operating state for use on a vessel, the vessel descends and lands on the water by operating the valve to release the air in the air bag, so it can be used immediately and there is no staff present. Easy to operate.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

As shown in FIGS. 1 to 4, a support structure 1 having a required height and length and having a concave shape when viewed from the front and rear directions.
At least two air bags 2 are installed symmetrically inside the support structure 1, and when the air bags 2 are deflated, a boat, cruiser, etc. that enters the support structure 1. A small boat 3 is lifted and supported by air force by inflating an air bag 2.

The support structure 1 is made of synthetic rubber and is hollow and filled with air to provide buoyancy. The structure is similar to a floating dock by having enough buoyancy to maintain its submerged state, and the overall rigidity, especially the rigidity of the left and right side walls, is increased to support the small vessel 3 in the stored state. To maintain a concave shape without the side wall escaping outward even when

Further, the air bag 2 is formed by fixing the periphery of a rubber plate 2a placed between a position close to the center of the bottom surface of the support structure 1 and the upper part of the inner surface of the side wall to the inner surface of the support structure 1. Two air bags 2 are provided facing each other on the left and right sides, and each air bag 2 has an air pipe 5 connected to a compressor 4 connected to a valve 6 as shown in FIG.
By injecting compressed air into the air bag 2, the air bag 2 inflates and protrudes from the left and right sides so that the inside of the support structure 1 is occupied by the air bag 2, and air is injected through the valve 6. When the air inside the bag 2 is let out, the air bag 2 contracts so that the inside of the support structure 1 becomes concave.

Note that the inside of the air bag 2, that is, the rising portion 2b of the portion fixed to the bottom surface of the support structure 1, is provided with rigidity or reinforcement so that the air bag 2 is in an approximately upright state when inflated. The support structure 1, which is equipped with a material and an air bag 2 inside, is placed in parallel on the quay wall 7 of the port, as shown in an example in FIG. Keep it moored.

When storing a small vessel 3 such as a boat or a cruiser, the vessel 3 is entered inside the support structure 1 as shown in FIG. 1 with the air bag 2 in a deflated state. Since the bottom of the support structure 1 is submerged in water, the vessel 3 can easily enter the support structure 1, and once the vessel 3 is located inside the support structure 1, the valve 6 to inject compressed air from the compressor 4 into each air bag 2. As a result, each air bag 2 inflates and protrudes inside the support structure 1, so that the support structure 1
At the same time as the seawater inside the vessel is discharged, the vessel 3 is lifted up by the air bag 2, and is lifted higher than the sea level as shown in FIG. At this time, air bag 2
The lower rising portion 2b stands upright on the support structure 1 to prevent it from bulging inward and escaping from the support structure 1. Furthermore, the side wall of the support structure 1 is provided with rigidity. Therefore, when the air bag 2 is inflated and the ship 3 is lifted up, the air bag 2 inflates and stretches upward, and the ship 3 is squeezed by the air bags 2 protruding from the left and right sides. This way you can easily lift it.

When lifted by the expansion of the air bag 2,
Seawater does not adhere to the bottom outer plate of the ship 3, and it is possible to prevent algae and shellfish from adhering to it.

In the above, when a plurality of ships 3 are supported in sequence on a plurality of support structures 1, if adjacent support structures 1 are connected to each other, they can be supported when inflating the air bladder 2 and lifting the ship. By pressing the side walls of the structure 1 together, it is possible to prevent each other from escaping to the outside, and the strength can be increased.

When landing on water for use from the stored state as described above, the valve 6 is operated to release the air inside the air bag 2 to the outside. As a result, the air bag 2 is contracted by the weight of the ship 3 and the ship 3 descends, and as the air bag 2 contracts, seawater begins to enter the support structure 1, so the ship 3 lands on the water, and from then on, the inflow begins. Air bag 2 due to seawater
The air inside is squeezed out, resulting in the state shown in Figure 1. The above operation is performed simply by squeezing and releasing the air in the air bag 2 using the valve 6, so it can be easily operated by the user of the vessel 3 without the presence of a staff member, even in the early morning or at night. However, the ship 3 can be used easily and quickly.

It should be noted that the present invention is not limited to the above-mentioned embodiment. For example, the case where one ship 3 is supported by one support structure 1 has been illustrated, but as shown in FIG. 1 may be arranged and connected in the front-rear direction, and the center portion of the ship 3 may be supported separately by the two support structures 1. This has the advantage that if the ship 3 is long, it is not necessary to prepare a long support structure 1, and since the ship 3 is supported by the front and rear support structures 1, it can be supported stably.

In addition, although the support structure 1 is made of synthetic rubber and is molded into a hollow concave shape to provide rigidity and has air sealed inside, each support structure 1 can be made to have buoyancy without being made of rubber. It may be used as a floating bridge that can follow the ebb and flow of the tide.Also, the air bladder 2 arranged on the inner surface of the support structure may be constructed by fixing the periphery of the rubber plate 2a to the inner surface of the support structure 1. As shown, by making a sealed bag in advance,
This bag may be held on the inner surface of the support structure 1.

[Effects of the invention] As described above, according to the storage device for a small boat of the present invention, it is made concave when viewed from the front and back so that a small boat can enter from the front and rear directions, and even if it supports a small boat, it will not sink. At least two rubber air bags are arranged symmetrically on the left and right inside the support structure, which has a buoyancy that allows it to follow the ebb and flow of the tide. is connected to an air supply source through a valve, and the air bladder is inflated and inflated to lift the small vessel onto the support structure. By inflating the air bladder after the vessel enters the inside of the support structure, the air bladder supports and pushes up the vessel, and the vessel is easily lifted above the support structure floating on the sea. Since the ship can be held in the same position and supported by two air bags on each side, the ship can be stably and safely supported, lifted and stored.
Therefore, algae and shellfish do not adhere to the bottom shell when not in use, and in addition, there is no need for a crane or a worker to operate the crane, which is required when storing the ship on land, and large-scale equipment can be omitted. It can be stored easily and in a short time, and when changing from the stored state to the use state, all that is required is to remove the air from the air bag, making it easy to use and in a short time. However, it can have the excellent effect of being able to be used and stored freely.
