Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a dome-shaped membrane roof for a swimming pool, which was limited to summer use, and inflates the air dome by blowing air from an internal combustion engine. This article relates to an air dome pool that uses the heat generated by the cooling section of an internal combustion engine to heat the pool water, making it possible to use it year-round. (Problems to be solved by conventional technology and invention) Conventional pools, especially swimming pools, were often installed outdoors, and their use period was limited to two to three months in the summer. The year-round pool has a permanent roof, is equipped with heating facilities, and is also equipped with equipment to heat the pool water.

However, the above-mentioned pools that can be used year-round require large-scale equipment due to the installation of a permanent roof, and also require separate heating and heating facilities, making it economically difficult to install.

On the other hand, the technology to adopt air domes for pools as a heat retention measure instead of a permanent roof was introduced in 1986-32465.
It is disclosed in the No. That is, as a heated dome, the hollow part of the sheet material having a hollow part is filled with gas to cover the top surface of the pool f. It is from et al.

Although this prior art invention is easy to construct a facility and keeps the inside of the pool warm and can be used outside of summer, it requires extensive work to extract the gas and fold it when the dome is removed and stored. Not only is it open-faced, but
In order to maintain the water temperature at a predetermined temperature, it was necessary to secure a new heat source and supply hot water into the pool.9 Another conventional example is the invention disclosed in Japanese Patent Application Laid-Open No. 62-21970. This invention is an air dome for a pool, in which the entire predetermined area of an outdoor pool or the like is surrounded by a film body, and the outside air is heated by increasing the pressure of outside air taken in from one or more blowers installed inside the film body. Hello
In an air dome in which a film body to be stretched by IJ is protected by a net provided on the outside of the film, a sheet-like soundproof wall sandwiched between the net and the film body protects the film from It is an air dome that surrounds the lower part of the circumferential side of the air dome.

Although this prior art invention was devised to prevent the noise inside the pool from leaking to the outside, like the above-mentioned swimming pool thermal dome, the folding work when removing and storing the dome was complicated and large-scale. It was necessary to secure a heat source that would supply hot water to keep the water temperature at a predetermined temperature.

The present invention has been made in view of the above circumstances, and its purpose is to use an internal combustion engine to drive a blower for inflating an air dome, and to supply cooling water to the cooling section of the internal combustion engine. Pool water is used as a part of the system, and the pool water is heated at the same time as the engine is cooled so that the pool water can be heated and used all year round.If necessary, an air dome can be contracted into a bellows-like state on one side of the pool. To provide an air dome pool that can be folded, and when in use, only needs to be moved in one direction to stretch the bellows-like state, the dome is easy to store and assemble, and can be constructed at low cost. There is a particular thing. (Means for Solving the Problems) The air dome pool according to the present invention has a membrane roof formed to cover the top surface of the pool with limbs, a blower that supplies air to pressurize and support the M roof, and 5. Drives the blower. The system is equipped with an internal combustion engine that connects to the cooling part of the internal combustion engine to supply hot water to the pool, and a hot water pipe and a drain pipe that discharge the water. Hollow side walls are provided facing both ends of the pool in the longitudinal direction, and agricultural bodies having hollow bones are stretched between the hollow side walls to cover the top surface of the pool, so that the hollow bones and the membrane tree can be folded. It is shaped.

(For f1l:) Fix the lower periphery of the membrane roof to the pool side so that the membrane roof covers the top surface of the pool.

Next, the internal combustion engine is activated, and its driving force turns the blower, sending air from the blower into the roof of the IIIS to form a dome covering the top surface of the pool.

On the other hand, as a means for cooling the internal combustion engine, 1-liter water is used in addition to normal cooling water. The pool water is sent to the cooling section of the internal combustion engine through the drain pipe, and the waste water heated by the cooling section turns into hot water and supplies hot water to the pool through the hot water pipe.

thus. The internal combustion engine can be cooled and the water in the pool can be heated to a predetermined temperature at the same time.When storing the air dome, the membrane roof, which is formed into a bellows shape, is placed on one side of the pool and on the other side. lIm
The dome is moved together with the wall, and the bellows part is contracted and folded.9 Then, when in use, the folded dome only needs to be moved in one direction to unfold the bellows-like state.

In addition, between internal combustion engines (for example, when using a reciprocating piston engine, there is a pool of water in addition to normal cooling water in the cooling section that cools the cylinders, pistons, cylinder cylinders, intake and exhaust valves, etc. that are the parts around the combustion chamber. Cooling is performed using water. In this case, in order to cool the cooling part of the internal combustion engine, a heat exchanger (6) is installed near the internal combustion engine ('2J) as shown in Figure 4 in this example.

However, the shape of the pool is not limited to a rectangle, but may be an ellipse, a gourd shape, or any other h-curved shape.The hollow side wall 0θ is filled with air or an inert gas such as a rim. Then, between the two opposing hollow side walls a9, an Ill body aα having hollow bones (9) is stretched, one of the hollow side walls is fixed, and Ikekata's hollow gAl! Aθ is movable to make it easy to fold and stretch into a bellows shape. Figure 2 CB) shows the air dome (4) about to be folded to one side.

FIG. 5 is a partially cut-away perspective view showing another embodiment of the membrane roof, and is a perspective view showing a suspended lI roof horizontal structure in which the membrane roof Ob is formed without using hollow ribs (9). .

And both pillars αe. A guide wire guide is placed between the tops of the ae. A large number of hanging wires ■■■ are suspended from this guide wire via a pulley α9, and the lower ends of the hanging wires ■ are fastened to the ceiling of the membrane roof αυ at predetermined intervals. In the figure, the lines indicate moving wires. The membrane roof has walls opposite to each other on both ends of the pool in the longitudinal direction, and an entrance/exit C3 is provided in the wall 122l.

Next, we will explain how to use the air dome pool.

First, the hollow bones {91 and the hollow side walls aθ are filled with air or an inert gas such as helium, respectively, to form the bones of the membrane roof, and the hollows facing both ends of the pool (1) in the longitudinal direction are Set up the side wall Oe. To seal the membrane roof, insert the lower periphery of the membrane roof knife into the groove (12a) of the sealing device α■ so as to cover the entire top surface of the pool (1), and fix it to the poolside in a sealed state.

The hot water heated in step 6) cools the internal combustion engine (2), and the hot water returned to the pool through the hot water pipe (8) serves to warm the pool water. Also, when storing the air dome 4), as shown in Figure 2 (B) and Figure 3,
When the hollow + 11 wall αθ on one end side of the bellows-shaped roof 01l is pushed toward one side of the pool, the pulley track attached to the hollow bone (9) rolls along the trajectory α. , and the lower end of the membrane main wall also moves along the groove (12a), and the bellows part is contracted and folded toward the other hollow side wall wall. When in use, all you have to do is move the folded dome in one direction so that it forms a bellows-like shape. <Effects of the Invention> As can be seen from the above description, the present invention uses an internal combustion engine to drive a blower for inflating an air dome, and uses pool water as part of the cooling water for the cooling section of the internal combustion engine. Therefore, the pool water can be heated using the residual heat of the internal combustion engine that is the power source, and in combination with the air dome, the pool water can be maintained at a predetermined temperature extremely economically.

Therefore, 1-le can be used throughout the year. Further, in the present invention, since the air dome can be folded into a bellows-like state on one side of the pool, the storage operation can be easily and easily carried out. Furthermore, even when in use, the air dome folded into a bellows-like shape only needs to be moved in one direction to stretch the bellows-like state, and assembly is extremely simple.
