Description

[Detailed description of the invention] "Industrial application field" This invention is suitable for long-term environmental observation, underwater sightseeing, underwater sightseeing in the sea, lakes, rivers, etc.
This invention relates to an underwater walkway that allows leisure sports to be carried out safely and comfortably.

"Prior Art" Conventionally, underwater observation and leisure sports have been carried out using diving equipment such as the Aqua Lung, or by using a submersible.

Diving equipment such as the Aqualung has the advantage of allowing you to maintain freedom of movement underwater for a certain amount of time; Underwater observation over a wide range of areas is now possible.

``Problem that the invention aims to solve'' However, the Aqualung requires skill to use and is not common, and it also requires multiple workers to communicate underwater with each other in language, Unable to keep track of time or work, there was a sense of isolation and anxiety, and of course it was impossible to take off the equipment and take a break, and there was always the risk of an accident.

Furthermore, if a person suddenly ascends from a deep place, there is a risk of so-called diving disease. In other words, for example, when resurfacing after working at a depth of 30 meters or more, it is necessary to depressurize underwater for twice the working time to prevent diving disease, but the remaining water of the Aqualung must be decompressed underwater. There may be cases where there is not enough air for that amount of time, or there may be cases where an emergency accident forces the person to ascend to the surface.

In this regard, although submersibles can eliminate the above-mentioned dangers and dissatisfaction, the equipment is large-scale, and it is not possible to enjoy underwater sightseeing at a low cost.

Therefore, in the past, there have been examples of experimental underwater staircases and underwater promenades, but they were all made with the purpose of being able to be used with clothes on, so they were completely confidential. The internal pressure is atmospheric pressure (one atmosphere).

With this atmospheric pressure method, in order to maintain the strength of the building to withstand water pressure, it is necessary to strengthen both the materials and structure, and underwater construction is also large-scale, increasing costs and destroying the environment. will be invited.

This invention was devised to solve the above-mentioned problems. It can be assembled with simple construction without destroying the environment, and it can be easily used for underwater sightseeing without using equipment such as an aqualung.
The purpose is to enable people to enjoy underwater sports.

``Means for Solving the Problems'' The present invention is an underwater walkway body installed underwater, which is open at least at the lower end, and from the lower end of a synthetic resin case that stores air blown out from below.
A plurality of pedestals are provided hanging down, the lower ends of the pedestals are fixed to the bottom of the water, and a floor plate is further provided below a predetermined portion of the synthetic resin case to form an air chamber body, and the plurality of air chamber bodies are connected. It is composed of:

In addition, the synthetic resin case is formed into a semi-cylindrical shape with the lower end and both ends open, and both ends of each of the synthetic resin cases of adjacent air chamber bodies are connected in an airtight manner, so that a plurality of the air chamber bodies can be connected in parallel. Connect to.

Furthermore, the synthetic resin cases are made into a semi-cylindrical shape with only the lower end open, and the height positions of the synthetic resin cases in the water in adjacent air chamber bodies are different.
The air chamber body is connected to the synthetic resin case in a stepped manner.

"Function" In the above-mentioned configuration, the air blown out from below is always stored in the synthetic resin case of the air chamber body, so if only the upper part of the neck is let out into the synthetic resin case. , it is possible to breathe without using equipment such as an aqualung, and since there is a floorboard provided below the synthetic resin case, if you stand on this floorboard, you can breathe only from the neck above. The position of the product inside the synthetic resin case can be maintained.

The lower ends of the plurality of pillars hanging from the lower end of the synthetic resin case are fixed to the water bottom, so the posture of the air chamber body in the water is stable, and the plurality of air chamber bodies can be connected together. Because of this structure, it is possible to sequentially move inside each air chamber by walking on the floorboards while breathing the air inside the synthetic resin case.

In this case, the synthetic resin case is made into a semi-cylindrical shape with the lower end and both ends open, and both ends of each synthetic resin case in adjacent air chamber bodies are connected in an airtight manner to connect a plurality of air chamber bodies in parallel. When connected, a long corridor-like walkway can be formed.

In addition, the synthetic resin case is made into a semi-cylindrical shape with only the lower end open, and the height positions of the synthetic resin cases in the water in adjacent air chamber bodies are different.
By connecting the air chamber bodies so that the synthetic resin case has a stair-like posture, it becomes possible to walk up and down underwater. In this case, when moving between adjacent air chambers, the robot must first go underwater and stick its head out into the adjacent synthetic resin case.

"Embodiment" The drawing shows an embodiment of the underwater walkway body of the present invention, in which the air chamber body A has an arch-shaped iron frame at both ends of a transparent synthetic resin case 1 in the shape of a semicircle with an open bottom end. 2, and suspending the pillars 4 from the lower ends of the four corners of the synthetic resin case 1,
The lower end of this pedestal 4 is fixed to the bottom of the water, and a floor plate 3 is provided below the synthetic resin case 1 at a predetermined location. Synthetic resin case 1
The floorboard 3 is installed and fixed at a height position where it comes out inward.

An air inlet pipe 6 is installed at the lower end of the synthetic resin case 1 in such a way that its open end is visible inside, and this air inlet pipe 6 is connected to an external compressor on the water, on the ground, etc. Since the high-pressure air is fed into the synthetic resin case 1, the synthetic resin case 1 is always filled with fresh air.

Further, as a means for fixing the lower end of the pedestal 4 to the water bottom, a gravity member 5 fixed to the water bottom is used.

Further, a handrail 7 is arranged between the pillars 4 at the side end between the synthetic resin case 1 and the floorboard 3, at the position where the hand is lowered when standing on the floorboard 3,
Ensures safety when walking.

Next, upper and lower joints 8 and 9 are protruded from predetermined positions of the pillar 4 at both ends of the air chamber body A.
This serves as a mutually fixed part when connecting adjacent air chamber bodies A in parallel. In this case, by providing a step between the joints 8 and 9 of adjacent air chamber bodies A, the air chamber bodies A can be connected with the synthetic resin case 1 in a stepped position.

In addition, when connecting a plurality of air chamber bodies A in parallel to form a long corridor-like walkway, adjacent air chamber bodies A
A packing is arranged between the opposing iron frames 2 of the synthetic resin cases 1, and each synthetic resin case 1 is placed in succession.
It will be necessary to ensure airtightness.

``Effects of the invention'' Since the invention has the configuration described above, if the air chamber bodies are connected in parallel to form a long corridor-like walkway, the synthetic resin case of each air chamber body can be This creates a continuous space, so you can enjoy a walk underwater by walking on the floorboards. In this case, since the synthetic resin case is transparent, underwater observation can be enjoyed, and furthermore, by connecting the air chambers in a stair-like manner, it is also possible to move to a predetermined facility installed at the bottom of the water.

In addition, at least the upper half of the body is exposed inside the synthetic resin case, which is filled with air and stored, so it is possible to breathe naturally and safely without the use of equipment such as the Aqua Lung, and the lower half of the body can be submerged underwater. Since the robot moves through each pair of air chambers in this state, the resistance of the water generates a considerable amount of momentum, making it effective as an underwater sport.

Furthermore, since the pressure inside and outside the synthetic resin case is balanced, it does not require as much strength in terms of material and structure as the atmospheric pressure method, which is expected to reduce production costs, and it is possible to use gravity materials as the pillars. If you remove it from the tank, it becomes possible to remove and move the whole thing, which makes it extremely simple, and allows you to make effective use of idle dry docks and unused diving pools to provide a place where you can train while getting close to the water. It exhibits excellent effects.
