Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveling body directly above and below the water surface, and more particularly, to a water body above and below the water surface which can be used both as a playground equipment and a practical simple high-speed boat. It relates to a dual-use traveling body. [0002] The following two prior arts are typical of marine propulsion mechanisms that use compressed gas as part of a drive source. One is disclosed in Japanese Utility Model Laid-Open No. 5-82799, and the other is disclosed in JP-A-2001-130489. The former is briefly described with reference to FIG. The jet water jet generated by the impeller 105 rotated by the drive shaft 107 is ejected from the rear to generate a propulsion force, and the compressed air A generated by the air compressor 111 is used.
Is added in the middle of the jet stream to accelerate the jet stream. [0004] Referring to FIG. 4, the latter is briefly described.
A jet generated by the water jet is injected from an injection port 210 to obtain a propulsion force.
1 is configured such that compressed air is supplied from the air compressor 201 that is separately driven into the same injection port 210 to increase the water flow propulsion. [0005] The above two examples are intended for relatively large vessels of at least several tons or more. Both of them use a propulsion impeller and a power machine (engine) for rotating the impeller. have. Almost all small boats and playground equipment used on the shore and the like that travel at high speed have an internal combustion engine using a fossil fuel such as gasoline or light oil. [0006] As described above, boats having an internal combustion engine disperse harmful exhaust gas into the surrounding water and air, and are generally troublesome with exhaust noise (the smaller and simpler the muffler is, the more the muffler becomes). Is incomplete and troublesome), and the surrounding environment is remarkably polluted by dropping a part of petroleum used as an energy source or lubrication to the surroundings. [0007] In addition, although there is a rare case where a battery is loaded and propelled by electricity, there is still chemical contamination due to the electrolyte used. The internal combustion engine-equipped engine also has disadvantages in terms of convenience in actual use, such as replenishment of fuel, replacement of engine oil, lubrication of rotating parts, and much maintenance. [0008] In addition, considering the fun as a playground equipment from a different viewpoint, the conventional playground equipment merely runs around on the water, and it is hard to change. Further, when viewed as rescue equipment at a beach or the like, conventional boats take a long time to start running with an engine and cannot be used practically. Standing idling with the engine running was also a source of pollution, fuel costs were terrible, and the mooring location did not give rise to the idea of having a regular beach at the beach. SUMMARY OF THE INVENTION The present invention has been made to solve all the above-mentioned problems, and is claimed in claim 1.
The solution according to the invention is provided with a generally thick plate-shaped main body having a hollow portion capable of being sealed therein, and provided at one longitudinal end of the main body so as to extend in the same longitudinal direction, and a base portion communicates with water by a passage. At least one water jetting cylinder, a high-pressure cylinder detachably provided in the hollow portion,
An air pipe from the high-pressure cylinder to an air injection nozzle that opens into the water jetting cylinder through the pressure reducing valve and the opening control valve in this order, and an operation lever that adjusts the opening of the opening control valve; A traveling body on / below the water surface having an openable / closable water intake port communicating with the hollow portion. 1 and 2, an embodiment of the present invention will be described. The main body 1, which has a streamlined boat-like thick flat plate shape as a whole, has a hollow portion 1A at substantially the center,
The hollow portion 1A can be covered with the lid 10 in a watertight manner. At the lower part of one end of the main body 1 in the longitudinal direction, a generally hollow cylindrical water jet tube 9 is provided so as to extend in the longitudinal direction, and the base of the water jet tube 9 is inclined with respect to the longitudinal direction. A passage 7 extending in the direction in which the water flows is communicated with the inside of the water jet tube 9. Although the number of the water jet cylinder 9 may be one as shown in the figure, a plurality of water jet cylinders branched from the base may be provided. A stabilizing fin 1B is provided at an appropriate position below the tail of the main body 1.
Is provided. At the bottom of the hollow portion 1A, a high-pressure cylinder 3 of air compressed to several hundred atmospheres is easily attached and detached by a band 3A. It is not necessary to limit the gas to be used to air, but if it is air, it has a good affinity with the surrounding environment and is very inexpensive in terms of price. Reference numeral 4 denotes a communication connection between the air pipe 41 and the high-pressure cylinder 3 which will be described below. The opening and closing cock 32 unique to each high-pressure cylinder is opened and closed to connect the inside of the high-pressure cylinder 3 and the air pipe. Communication with the road 41 is cut off. The pipe indicated by reference numeral 31 is an outlet pipe for displaying the air pressure in the high-pressure cylinder 3 with an air pressure gauge 11A provided near the head of the main body 1. The air line 41 is provided with a pressure reducing valve 5 and an opening control valve 6 in this order. At the end corresponding to the right end in FIGS. It is arranged coaxially inside the water jet tube 9. It should be noted that the opening position of the air injection nozzle 8 is closer to the end of the water jet nozzle 9 than the opening position of the passage 7 in the water jet nozzle 9. The pressure reducing valve 5 and the opening control valve 6 of the air line 41
And a take-out pipe 51 extending from an appropriate position between the air pressure gauge 11B and another air pressure gauge 11B. The air pressure gauge 11B displays the air pressure after pressure reduction by the pressure reducing valve 5 as a meter. The opening control valve 6 rotates a cylindrical valve rod having a communication opening of the same diameter as the inner diameter of the air pipe 41 around its own axis within an angle of 0 to 90 °. This is a well-known type of valve that performs opening and closing adjustment so that air flowing through the air line 41 is adjusted in the range of 0% to 100% and flows toward the downstream air ejection nozzle 8. 6
One can easily be adjusted via the wire 62 by turning one. A pair of grip handles denoted by reference numeral 2 is a grip handle provided near the head of the main body 1, and usually a passenger grasps the handle and crawls on the upper surface of the main body 1, or sits straight. Will be. The adjustment lever 61 described above may be of a well-known motorcycle type that can be operated by another finger of the same hand holding the handle 2. The hollow portion 1A of the main body 1 is sealed by a cover plate 10. The type of the cover plate 10 may be a hinge-rotating type or a type in which a separate body is fitted from above. The point is to obtain sufficient watertightness when closed. A part of the main body 1 has a water intake 1 that can be sealed.
C is drilled. This is because the hollow part 1
This is an intake port for taking in water from outside into A and sinking the running body below the water surface to enjoy it as an underwater running playground equipment. At this time, the side of the body 1 where the draft line comes is determined by the amount of water to be introduced, the material (specific gravity) and the volume of the body, as shown by Archimedes' principle. In the figure, a notch line indicating a suitable amount of introduced water is provided so that a passenger can select this as desired. Next, the method of using the traveling body of the present invention, that is, the operation method will be described. First, as a preparation, a commercially available high-pressure cylinder 3 is fixed at a predetermined position. It can be used in common with the high-pressure cylinder used for Aqualung, which is a popular diving tool, and can be purchased at low cost and easily. The degree of pressure reduction by the pressure reducing valve 5 is arbitrary,
About several to several tens of atmospheres are suitable for ordinary use. All this completes the preparation. Then, the rider may ride on the vehicle, turn the adjustment lever 61 to open the opening adjustment valve 6 as appropriate, and eject compressed air from the air injection nozzle 8. The compressed air jetted from the air jet nozzle 8 is almost 1 at a shallow position below the water surface where the traveling body runs.
The water expands rapidly in water having a pressure equal to the atmospheric pressure and presses the surrounding water, and is pushed out as a jet toward the rear in the longitudinal direction according to the internal shape of the water jet tube 9. When the water is extruded as a jet, the water is exhausted and the pressure drops, so that the surrounding water flows into the jet through the passage 7, and the jet is jetted as a continuous jet without interruption. It is jetted backward from the cylinder 9. The above is the mechanism of propulsion of the traveling body of the present invention. In this respect, unlike a conventional water jet propulsion device, it can be called a water rocket propulsion device with a boost pressure control device that can control both the pressure and discharge amount of ultra-high pressure compressed air. When the traveling body is sunk below the surface of the water to travel, it is sufficient to introduce an appropriate amount of water into the hollow portion 1A and sink the main body 1 to a desired draft line as described above. The operation of the adjusting lever and the like are exactly the same as the case of traveling on the water surface. Underwater traveling is possible only because there is no internal combustion engine. In the embodiment described herein, the passenger does not intentionally provide a rudder to simplify the configuration, and the passenger changes the direction easily using his own hand or foot. However, it is extremely easy to provide a rudder, for example, if a part of the stable fin 1B is made movable, it is sufficient. The effects of the present invention are enormous and various. First, (1) since the internal combustion engine is not used for both a practical boat and a playground equipment, there is no pollution such as exhaust gas and noise, so that the environment is not impaired. Since there is no water contamination, it can be used safely even in aquaculture and fishing grounds. (2) Since it can be started very quickly, it is most suitable as a rescue aid for a drowned person at a beach or the like.
In other words, there is no need to wait in an idling state like a conventional motorboat, there is no need to wait quietly with no sound and no exhaust. Is overwhelming. (3) There is almost no maintenance cost. No fuel is required because no internal combustion engine is used, and no lubricating oil is required because there are no rotating parts. (4) Since there is no rotating screw, there is no risk of injuring nearby bathers and it is extremely safe. (5) Since it can be run on the water surface or under the water surface, it has a wide range of choices as a playground equipment and is very interesting. (6) Ultra-small and ultra-light, even women can handle the main body with one hand. Easy to carry and move. (7) The structure is simple, the device can be manufactured at relatively low cost, and since there is no consumable part, the performance of a new product can be guaranteed forever. In addition, there are very great advantages and effects, such as easy acquisition of high-pressure air as a propulsion energy source and inexpensiveness.
