Description

  The present invention relates to a fluid injection and agitation device, and more particularly to a fluid injection and agitation device that can efficiently inject and agitate a second fluid into a first fluid with a simple configuration.

In general, when mixing two or more types of fluids, for example, when uniformly dispersing various powders and chemicals added to the fluid, a step of injecting chemicals and the like, and a step of stirring other than an automation machine Is often a separate process. In addition, tools and devices for injection are used in the injection step, and tools and devices for stirring are used in the stirring step.
If stirring is not performed, mixing after injection will use convection due to temperature differences and concentrations of each fluid, etc., and expect diffusion of substances. In that case, it will take a lot of time. It has become.
In the case of mixing of reactive substances or heating by steam injection or the like, it is desired to perform stirring quickly.

Conventionally, for example, an in-container liquid stirring device that mixes liquid in a container so as to be uniform is known (see Patent Document 1).
The container liquid stirrer disclosed in Patent Document 1 stirs a liquid such as printing ink or petrochemical contained in a container so that a mixture such as a solvent becomes uniform.

Japanese Patent Laid-Open No. 11-147032

However, the in-container liquid stirring device disclosed in Patent Document 1 has the following problems.
That is, the above-mentioned liquid stirring apparatus in the container is configured to rotate the rotation shaft having the stirring blade attached to the tip by driving the air motor. This stirring blade is normally in a downward state, and when rotated, it is opened in a direction orthogonal to the rotation axis by centrifugal force. The air motor is supported by a clamp, and the clamp is attached to a telescopic mounting base. It has been. For this reason, the number of parts is large and the structure is complicated.
In addition, the stirring blade is formed in a thin blade shape, and since the rotating shaft is long, there is a risk of unexpected injury if it is not handled carefully.
Furthermore, in the container liquid stirring apparatus disclosed in Patent Document 1, the liquid in the container is only stirred, and a fluid for stirring is not injected.

By the way, the necessity of stirring two or more types of fluids is not limited to, for example, mixing the liquid in the container.
That is, for example, in lakes and ponds, it is necessary to agitate stagnant water so as to suppress mass growth of blue-green algae.

Here, in many lakes and ponds, there is almost no convection of water in the interior, so the water remains accumulated and often becomes stagnant.
For this reason, especially in the case of lakes and ponds where there is little water flow, especially in the summer, water flies occur to cover the surface of the water, creating a nasty smell to create an anaerobic environment, and causing aquatic organisms to be deficient in oxygen. Etc.

Countermeasures for blue sea cucumber include pumping and removing by pumping, radiating ultrasonic and ultraviolet light to destroying blue sea bream cells, and convection from the low temperature layer at the bottom to reduce the temperature of the upper water generated by blue sea bream. A wide range of technologies such as water flow generators and methods that use the updraft caused by rising air released from the aeration device, and water quality improvement methods for the inflowing rivers to reduce the nutrients of the sea bream, Research and development is being conducted as a large-scale, wide-ranging approach to cope with the occurrence of aoko.
However, any of these methods requires a large-scale facility, is technically difficult, and increases the cost of the facility, so that a practical method that requires low cost has not yet been obtained.

One example of the difficulty in measures against blue-green sea bream is that the conditions of the location where the water area exists are different, and the combination ratios of the factors that cause the growth of blue-green algae are different.
For example, even with a single nutrient device, the mineral components obtained by dissolving the components of the soil and rocks that form the lake are various, and if there are inflow rivers, the nutrient components contained in the rivers are also different. Or, of course, the type of aquatic life is different.
As a result, one measure is rarely sufficient. It is also necessary to take measures to prevent adverse effects on other aquatic organisms as countermeasures against blue-green sea urchins. Furthermore, even if it is not a problem in large-scale water areas, it is necessary to satisfy issues such as quietness and scenery in water areas near the residence. It has become.

As described above, once the auko is proliferated in large quantities, various harmful effects occur, and it is difficult to remove the aoko. Therefore, if large-scale growth of cyanobacteria such as blue-green algae can be suppressed, naturally large-scale generation of blue-green algae can be suppressed.
In order to prevent the occurrence of sea cucumber, water such as lakes and ponds is always in convection, which eliminates the stagnation of the water and prevents the temperature difference between the surface and lower layers of the water. It is important to eliminate the oxygen deficiency. And in order to always produce convection in water of lakes and ponds, it is an indispensable condition to stir the water efficiently.

Therefore, for example, when the liquid stirring device in the container of Patent Document 1 is used for stirring water in lakes and ponds, the following problems arise.
That is, in the above-described liquid stirring apparatus, the liquid is only stirred by the rotating stirring blade, and the range of influence of the stirring is narrow. Therefore, even if the water in the lake and pond is agitated, the water in the vicinity of the rotation range of the agitation blade is only agitated. In order to mix the surface layer and the lower layer, it is necessary to use a large-scale power that generates a large amount of high-speed water flow, and it is not possible to eliminate an oxygen deficient state such as the bottom of the water.
As a result, it is difficult to suppress the large-scale generation of the water-bloom using the in-container liquid stirring device of Patent Document 1.

  Also, not limited to lakes and ponds, for example, when replacing pool water or injecting disinfectant, conventionally, it is expected to mix naturally, or disinfect disinfectant pre-diluted with a bucket or the like near the outlet of the circulation pump In most cases, it was a cautionary call, etc., and it took time to fully disperse. Therefore, it is necessary to sufficiently agitate these fluids even when the water in the pond or the pool is replaced or the disinfectant is injected.

(Object of invention)
The present invention has been proposed in order to solve the above-described problems, and a fluid injection and agitation device that can efficiently inject and agitate a second fluid into a first fluid with a simple configuration. Its purpose is to provide.

In order to achieve the above object, a fluid injection and agitation apparatus according to the present invention includes a flexible nozzle that is formed of a flexible material and has a tube portion that ejects a second fluid into the first fluid at the tip. A fin portion of the flexible nozzle acting in a forward wave motion by the self-excited vibration of the flexible nozzle that is generated in the ejection of the second fluid in the first fluid acts on the first fluid. A fluid injection and agitation device for agitating the first fluid,
A nozzle holding body for holding the flexible nozzle and a fluid supply means for supplying the second fluid to the nozzle holding body are provided.

According to the fluid injection and agitation device of the present invention, when the second fluid is supplied to the flexible nozzle, the flexible nozzle causes self-excited vibration by the injection of the second fluid, and advances by the self-excited vibration. Since the fin portion of the flexible nozzle that has a sexual wave motion acts on the first fluid and swings irregularly, the second fluid is ejected in a dispersive manner, and the first fluid is moved by the whirling motion of the tube portion. Stir.
As a result, the second fluid can be efficiently injected and stirred into the first fluid with a simple configuration.
And when the fluid injection stirring apparatus of this invention hold | maintains a some flexible nozzle to a nozzle holding body, and arrange | positions the nozzle holding body in the water as 1st fluids, such as a lake, a pond, etc., a plurality Water from lakes and ponds is agitated by the flexible nozzle of the book, creating convection, which eliminates the stagnation of the water and the lack of oxygen deficiency. Can be suppressed. As a result, it is possible to prevent the occurrence of a large amount of blue water.

[First Embodiment]
Below, based on FIGS. 1-7, 1st Embodiment of the fluid injection | pouring stirring apparatus which concerns on this invention is described.

  1 is an overall view showing the fluid injection and stirring device 1, FIG. 2 is a view taken along the line II in FIG. 1, and FIG. , 5 are a front view and a perspective view showing the nozzle.

  The fluid injection and agitation device 1 of the first embodiment injects and injects water or air as a second fluid different from water such as a pond into water such as a lake or a pond as a first fluid, and By dispersing and stirring the water in the lakes and ponds, convection is generated and the oxygen deficiency state is eliminated. It is a device that tries to prevent.

The fluid injection and agitation device 1 includes a flexible nozzle (hereinafter simply referred to as a nozzle) 10 that is formed of a flexible material and has a flexible tube portion 10d that ejects water or air as a second fluid at the tip. And a nozzle holder 13 for holding the nozzle 10 in water such as a lake or a pond, and a fluid supply means 40 for supplying water or air for nozzle operation to the nozzle holder 13. It has a configuration.
The fluid supply means 40 includes a fluid supply device 41 and a fluid hose 42 that conveys water or air supplied from the fluid supply device 41 to the nozzle 10.

  Here, the nozzle 10 is an application of the nozzle disclosed in “Japanese Patent Application No. 2013-238060” filed by the present applicant, and “Patent No. 4711112” filed and registered by the present applicant. A nozzle having substantially the same shape and function of causing self-excited vibration is used.

That is, the nozzle 10 causes a bending motion by self-excited vibration caused by reaction force generated when water or air is ejected from the nozzle 10, and this bending motion is called a forward wave motion and is almost the same as that of a fish tail. Because it is the same motion, it generates a propulsive force or a stirring force. And it is formed in the shape which has flexible tube part 10d at the front-end | tip part so that water, such as a lake and a pond, can be stirred by the bending motion, it is formed with flexible materials, for example, silicon rubber.
As shown in FIGS. 4 and 5, the fluid supply device 41 and the nozzle 10 are connected by the fluid hose 42 via the pipe joint 11, and the fluid is supplied via the fluid hose 42. A predetermined pressure of water or air is sent from the device 41 to the nozzle 10.

The nozzle 10 will be described in more detail.
As shown in FIGS. 4 and 5, the nozzle 10 includes a nozzle main body 10a, a base end of the nozzle main body 10a, that is, a thin tube insertion portion 10b integrally formed on the fluid supply side, and the nozzle main body. The guide fin portion 10c is integrally formed on the distal end side of the guide 10a, and the thin flexible tube portion 10d is integrally formed on the distal end of the guide fin portion 10c.

The flexible tube portion 10d has an inner diameter of, for example, 1 mm and an outer diameter of, for example, 2 mm.
Therefore, the self-excited vibration of the nozzle 10, particularly the flexible tube portion 10 d, can be performed even with water or air fed by a weak water pressure or air pressure. As a result, an energy saving effect can be expected.

Further, the inner diameter of the narrow tube portion 11a and the flexible tube portion 10d is in the range of 1 mm to 2 mm, but is not limited to these dimensions, and has an appropriate diameter that facilitates the generation of convection. Can be adopted.
On the other hand, the pipe joint 11 is provided with a thin tube portion 11a. By inserting the thin tube portion 11a into the thin tube insertion portion 10b of the nozzle 10, the fluid hose is passed through the nozzle mounting hose 18 and the like. 42 and the nozzle 10 are connected.

Here, the self-excited vibration and the forward wave motion will be briefly described.
First, self-excited vibration will be described.
There are at least three actions as the action of the self-excited vibration nozzle on the fluid.

The first is an injection action. This is an action of injecting water or air (second fluid) fed from the nozzle 10d of the nozzle 10 into water (first fluid) such as a pond. It has nothing to do with self-excited vibration.
The second is a spraying action. This is because the nozzle 10 vibrates by itself and the position and orientation of the jet outlet 10d always change, so the injection position of the second fluid that has been pressure-fed to the first fluid in the environment is always the same. Change and inject. In this spraying action, since there are many injection locations in spatial coordinates, injection can be performed randomly. This spraying action is related to self-excited vibration.
The third is a stirring action. This is because the nozzle 10 continues the self-excited vibration, which can be called a progressive wave motion, and therefore, the action of stirring the first fluid in the environment and the transport of the first fluid in the environment by the progressive wave motion. This is the action of causing the flow to stir the first fluid directly. This stirring action is also related to self-excited vibration.
These three actions are performed at the same time, and do not occur alone, and all stop when the injection is stopped.

Next, the forward wave motion will be described.
The forward wave motion is a wave motion in which the bending point is directed from the base end portion of the nozzle 10 toward the nozzle tip portion, and the first fluid in the environment generally surrounded by the bending point is carried by the wave motion, thereby causing the flow to flow. Born.
This flow generates friction at the contact point between the flow of the first fluid in the new environment to the injection point of the nozzle 10 and the fluid itself, and the flow of the first fluid is also stirred at this portion. It is carried out. That is, since the volume to stir is large, mixing with the 1st fluid and the 2nd fluid in the nozzle 10 vicinity is accelerated | stimulated. Therefore, strictly speaking, the nozzle 10 agitates the first fluid (water such as a pond) and the mixed fluid of the first fluid and the second fluid (water or air).
In addition, the flow caused by the forward wave motion is a power source that promotes convection with respect to the first fluid, and has a larger force that promotes a larger flow than the case of only the wake caused by the jet flow of the nozzle 10. And even if the energy which the 2nd fluid ejected from the nozzle 10 has is the same, it can be said that producing a larger flow has a higher stirring efficiency.

As shown in FIGS. 1 and 2, the fluid injection and agitation device 1 includes a plurality of the nozzles 10 and the nozzle holder 13 that holds the nozzles 10 in a state where each nozzle 10 maintains its own operation region. It is configured.
In other words, the state in which the unique operation region is maintained means an interval at which the plurality of nozzles 10 do not interfere with each other, and the nozzles 10 are arranged at intervals of 30 cm, for example.

The plurality of nozzles 10 are respectively disposed in a water surface side underwater region and a water bottom side underwater region such as a lake and a pond. Each nozzle 10 is held by a nozzle holder 13.
The nozzle holder 13 includes a water surface holder 14 disposed in a water surface side underwater area such as a lake or pond, and a water bottom holder 28 disposed in a water bottom side underwater area such as a lake or pond. Has been.

The water surface holding body 14 is formed of, for example, a synthetic resin such as PP (polypropylene) or vinyl chloride, waterproofed wood, etc., and has a substantially bottomed cylindrical main body 15 and a lid 16 that covers the main body 15. It is comprised by the floating body structure.
The lid portion 16 is detachably attached to the main body portion 15 by bolts and nuts 17.

In the water surface holder 14, four nozzles 10 </ b> Aa serving as water surface nozzles are separated from the outer periphery of the main body 15 by a predetermined dimension via a nozzle mounting hose 18 at a portion of the outer periphery of the main body 15 that is immersed in the water surface. And evenly arranged so as to be relatively shallow from the water surface.
Each of these nozzles 10Aa is arranged so that the nozzle body 10a and the guide fin 10c are in the orthogonal direction of FIG. 1 in water such as a pond, that is, substantially parallel to the side surface of the body 15 of the water surface holder 14. It is arranged to be. At this time, the flexible tube portion 10 d at the tip of the nozzle 10 </ b> Aa faces in the direction opposite to the outer periphery of the main body portion 15 of the water surface portion holding body 14.

Further, as shown in FIG. 2, four bottom side nozzles 10 </ b> Ab serving as water surface nozzles are provided on the bottom surface part 15 </ b> A of the main body part 15 from the bottom surface part 15 </ b> A of the main body part 15 through the nozzle mounting hose 18. They are evenly arranged so as to be at a distance from each other and relatively deep from the water surface.
Similarly to the above, these nozzles 10Ab are also arranged such that the nozzle main body portion 10a and the guide fin portion 10c are substantially parallel to the side surface of the main body portion 15 of the water surface portion holding body 14. At this time, each nozzle 10Ab includes the flexible tube portion 10d at the tip thereof, and is arranged in a state of facing slightly downward from the bottom surface portion 15A of the water surface portion holding body 14.
Here, the nozzle 10Aa as the water surface portion nozzle and the bottom side nozzle 10Ab and the nozzle 10 are exactly the same, but the symbols are changed for convenience of explanation.

The nozzle hose 18 for supporting the fluid hose 42 and the nozzles 10Aa and 10Ab is formed of, for example, a thin copper pipe having a small diameter, and is connected to a metal manifold 20 as shown in FIG. ing.
Since the nozzle mounting hose 18 is formed of a thin copper pipe having a small diameter, the nozzle mounting hose 18 can be bent into a desired shape relatively easily and can be maintained. For this reason, the positions and orientations of the nozzles 10Aa and 10Ab can be adjusted, and only the nozzle 10 vibrates in this state.

The manifold 20 distributes the water or air sent from the fluid supply device 41 via the fluid hose 42 to the nozzles 10Aa and 10Ab. One end is connected via a fluid hose pipe joint 21.
The fluid hose 42 is inserted into the through hole for the hose formed in the upper surface of the main body 15 of the water surface holder 14 and the lid 16 with waterproofing.
The fluid supply device 40 and the fluid hose 42 constitute the fluid supply means 40.

Further, one end of the nozzle mounting hose 18 for the four nozzles 10 </ b> Aa as the water surface nozzles is connected to a side surface equal position of the manifold 20 via a joint 21.
The nozzle mounting hose 18 is inserted into the through hole for the nozzle mounting hose 18 formed in the side surface of the main body 15 of the water surface holding body 14 with waterproofing.

Further, the nozzle mounting hoses 18 for the four nozzles 10Ab serving as the bottom surface nozzles are connected to the equal positions on the bottom surface of the manifold 20 through the joints 21, respectively.
The nozzle mounting hose 18 is inserted into the through hole for the nozzle mounting hose 18 formed in the bottom surface of the main body portion 15 of the water surface holding body 14 with waterproofing.

  On the upper surface of the lid portion 16 of the water surface portion holding body 14, a water surface water sprinkling device 23 for watering the water surface such as a pond is provided. This water surface sprinkler 23 sprinkles water on the water surface so that it rains from above the water surface, thereby trying to make the water surface ripple.

The water surface sprinkler 23 includes a support column 24 formed of a pipe member erected on the upper surface of the lid portion 16 via a flange 24 </ b> A, and a horizontal member 25 formed of a pipe member provided at the upper end portion of the support column 24. And a nozzle mounting hose 26 that is inserted into the column 24 and has an upper portion divided into two, and a watering nozzle 10 </ b> C that is attached to the nozzle mounting hose 26 via the pipe joint 21. Has been.
The watering nozzle 10C has the same structure as the nozzle 10 but is given a different reference for convenience of explanation. The nozzle mounting hose 26 is formed of a copper pipe made of the same material as the nozzle mounting hose 18.

  As described above, the water bottom holder 28 is placed on a water bottom such as a pond and is connected to the water surface holder 14 while being suspended by a connection hose 29. The connection hose 29 is made of, for example, a nylon tube or the like, and one end of the connection hose 29 is connected to the manifold 20 via a pipe joint 30.

As shown in FIGS. 1 and 2, the water bottom holder 28 is formed in a ring shape and is connected to the other end of the connection hose 29 via a pipe joint 30.
The nozzle mounting hose 18 connected via the pipe joint 21 is provided on the outer periphery of the water bottom holding body 28, and a plurality of nozzles 10B serving as water bottom nozzles are respectively attached to the nozzle mounting hoses 18. ing.
The ring-shaped water bottom portion holding body 28 is formed of, for example, a SUS pipe or a copper pipe, and water or air flows through the inside.

The water bottom nozzle 10 </ b> B is composed of, for example, eight nozzles that are evenly arranged on the side surface of the ring-shaped water bottom holding body 28 via the nozzle mounting hose 18. The nozzle mounting hose 18 is provided to protrude outward from the outer periphery of the water bottom holding body 28 by a predetermined dimension. At the tip of each nozzle mounting hose 18, a flexible tube portion 10d at the tip of the water bottom nozzle 10B is provided. It is provided in the direction opposite to the water bottom holder 28.
Moreover, each water bottom part nozzle 10B is arrange | positioned so that the substantially flat surface part of each main-body part 10a and the guide fin part 10c may become substantially parallel to the bottom face of a pond.

As shown in FIG. 1, a buoyancy buoy 31 is attached to the connecting hose 29 in the middle in the length direction. The buoyancy buoy 31 can adjust the depth of the water bottom holder 28 by adjusting the amount of air injected into the buoy 31.
Further, by lifting the buoyancy buoy 31 to the maximum extent, for example, when the water bottom holding body 28 is pulled up, the lifting work can be easily performed.

  The water surface nozzles 10Aa and 10Ab and the water bottom nozzle 10B described above are selectively fed with water or air different from the water in order to agitate water such as a pond. The operation is performed by the control device 35 shown in FIG.

That is, the control device 35 supplies air or water to the water surface nozzles 10Aa and 10Ab, the water bottom nozzle 10B, etc. from either the air pump 41B or the tap water pump 41A constituting the fluid supply device 41 depending on the situation. To send to. The tap water pump 41A is used when the tap water pressure is low, but it is sufficient if it is not attached to a general tap water.
The air pump 41B and the buoyancy buoy 33 are connected by pipes P1 and P2, and the air pump 41B and the water bottom nozzle 10B are connected by pipes P1, P3 and P7. Valves 36 and 36 for switching are provided in the middle of these pipes P2 and P3, respectively, and a pressure gauge 37 for checking the air pressure and a pressure for checking the water pressure are provided in the pipes P4 and P7 leading to the water bottom nozzle 10B. A total of 38 is provided.

The tap water pump 41A and the water bottom nozzle 10B are connected by pipes P4 and P7, and the tap water pump 41A and the water surface nozzles 10Aa and 10Ab are connected by pipes P1, P6 and P61, and are used for tap water. The pump 41A and the water surface water spray nozzle 10B are connected by pipes P1 and P5.
In the middle of the pipe P4 connecting the tap water pump 41A and the water bottom nozzle 10B, the switching valves 36 and 36 and the pressure gauge 38 for checking the water pressure are provided. The switching valve 36 is provided in the middle of pipes P1, P6 connecting the pump 41A and the water surface nozzles 10Aa, 10Ab and pipes P5, P6, P61 connecting the pump 41A and the watering nozzle 10Ad. Each is provided.

The switching of the valves 36 for switching of the control device 35 is manually performed as appropriate based on various conditions.
In other words, detailed responses must be different depending on the water quality and aquatic plants such as lakes and ponds, the types of rocks in lakes and lakes, the components of rivers flowing in, sunlight and seasons.
For example, when there are aquatic plants and a certain amount of algae, they are switched between daytime and nighttime due to the difference in sunlight. When algae photosynthesize, the amount of oxygen in the water during the day is high, but it is low at night.
Even so, algae and the like consume oxygen at night, so it becomes an environment where fish suffers from oxygen shortage at night. In such a case, it is only necessary to switch to air at night to control the oxygen concentration to some extent.
As a rough guideline, the water supply is turned on at daytime and turned off at night, while the air is turned off at daytime and turned on at night.
In order to control the feed amount of water or air, that is, the flow rate, the pressure gauges 37 and 38 are checked while the switching valves 36 and 36 are opened.

Next, the movement of the water bottom nozzle 10B that oscillates irregularly when tap water is fed into the nozzle 10, here the water bottom nozzle 10B, will be described.
When tap water of a predetermined pressure is sent to the water bottom nozzle 10B and is ejected from the flexible tube portion 10d at the tip of the water bottom nozzle 10B, reaction force is generated by the ejection and injection, and the water bottom nozzle 10B Bending motion called forward wave motion by self-excited vibration occurs due to reaction force. And since water such as a pond is agitated by this bending motion, and the motion is repeated, a large convection C is generated. Therefore, the oxygen deficiency is eliminated by exchanging the water in the upper and lower layers. Can be prevented from occurring in large numbers.

(Effect of 1st Embodiment)
According to the fluid injection and agitation device 1 of the first embodiment configured as described above, the following effects can be obtained.

(1) When water or air supplied from the fluid supply means 40 is supplied to the nozzle 10 held by the nozzle holder 13, the nozzle 10 is formed of silicon rubber, and thus has flexibility. Due to the injection of water or air, the flexible tube portion 10d of the nozzle 10 swings irregularly in water such as a lake or a pond, and the liquid is diffused, so that the water such as a lake or a pond is agitated. As a result, two or more types of fluids can be efficiently stirred with a simple configuration.

(2) Water such as lakes and ponds can be agitated by water or air ejected from the flexible tube portion 10d at the tip of the nozzle 10. Therefore, it is possible to circulate and circulate the entire water of lakes and ponds, which enables the surface layer and lower layers of water to be replaced, and the water in lakes and ponds is constantly convected and circulated. Therefore, it is difficult to generate large amounts of cyanobacteria such as cyanobacteria, which can be prevented in advance.

(3) In the present embodiment, the nozzle 10 is made of silicon rubber, and the flexible tube portion 10d at the tip thereof has an inner diameter of, for example, 1 mm and an outer diameter of, for example, 2 mm. The tube portion 10d can perform self-excited vibration even with water or air fed by weak water pressure or air pressure. As a result, an energy saving effect can be expected.

(4) Since the nozzle holder 13 is composed of two types, a water surface holder 14 arranged in the water surface side underwater area and a water bottom part holder 28 arranged in the water surface side underwater area, When a pond or the like is large (wide) and the water depth is deep, both the holding bodies 14 and 15 can be arranged on the water surface side and the water bottom side, respectively. As a result, it is possible to sufficiently cope with the size (width) and depth of a lake or pond.

(5) A water surface sprinkler 23 is provided on the upper surface of the lid 16 of the water surface holder 14, and the water spray nozzle 10 provided at the upper end of the support 24 of the water surface sprinkler 23 is directed toward the water surface. Can be sprinkled to make it rain. Thereby, the water near a water surface can be stirred by making a water surface wave.
As a result, the water stirring effect in the vicinity of the water surface by the water surface sprinkler 23, the water stirring effect in the water surface side region by the nozzles 10Aa and 10Ab provided in the water surface holding body 14, and the water bottom holding body 28 are provided. Since each nozzle 10B can obtain the agitation effect in the water at the bottom side region, it can agitate water in lakes and ponds more effectively. It becomes difficult, and it is possible to prevent the occurrence of a large amount of blue sea urchins.

(6) The water surface sprinkler 23 is provided on the upper surface of the water surface holder 14, and the water sprinkling nozzle 10 provided at the upper end of the column 24 of the water surface sprinkler 23 causes rain toward the water surface.

This is the sum of the propulsive force generated by forward wave motion caused by excitation vibration. The direction of this propulsive force acts in the X-axis direction on the proximal end side of the nozzle 10.
However, since the base end portion of the nozzle 10 is fixed to the ring-shaped water bottom holding body 28 </ b> A via the nozzle mounting hose 18, the propulsive force generated in the nozzle 10 is a water dimension as a reaction force acting on the nozzle 10.

Each nozzle 10 is provided via the nozzle mounting hose 18. Further, each nozzle 10 is arranged to be slightly inclined downward (for example, an inclination angle of about 45 °). Therefore, injection, diffusion, and stirring can be performed on the layer from the bottom of the pond to the water surface.

  Here, the nozzle 10 arrange | positioned at the upper stage part is provided in the state protruded from the water surface. Therefore, when water is injected and injected from each nozzle 10, since the topmost nozzle 10 protruding from the water surface sprays droplets close to natural rain, the landscape is not impaired.

Further, a part of the nozzle 10 disposed in the middle stage is submerged in the water surface, and therefore, when the nozzle 10 performs an irregular swirling motion, the water is agitated, and the water surface is rippled. become.
Furthermore, even when the water level is variable and the nozzle 10 disposed in the middle stage protrudes from the water surface, since the nozzle 10 can spray liquid droplets close to natural rainfall, the landscape is not impaired. .

According to the fluid injection and agitation device 1A of the second embodiment configured as described above, the following effects can be obtained in addition to the effects (1) to (3).

[Application 1]
Next, an application example 1 of the fluid injection stirring apparatus according to the present invention will be described with reference to FIG.
The fluid injection and agitation device 1G of the first application example is a cold air blower 80 configured using the nozzle 10.
That is, in the cool air blower 80 of the first application example, random water droplets are discharged into the indoor space by the nozzle 10 so that the water droplets come into contact with the air in the indoor space and the heat of vaporization is generated by the wind sent by the blower. This is an application of the principle that is taken away.

  The cold air blower 80 includes a case main body 81 equipped with the nozzle holder inside. A water tank 82 is provided at the lower end portion of the case body 81, and a partition plate 83 is provided in the case body 81 in the vertical direction, whereby the inside of the case body 81 is connected to the wide first chamber 81A. It is partitioned into a narrower second chamber 81B. The lower end portion of the partition plate 83 is disposed with a gap from the upper surface of the water tank 82.

Inside the first chamber 81A, a water conduit 84 equipped with the three nozzles 10 facing upward at the tip is fixed by a fixture (not shown). The rear end portion of the water conduit 84 is located outside the case body 81 and is connected to another water conduit 85 connected to the supply pump 86 at that position.
The water conduit 84 constitutes the nozzle holder.

The supply pump 86 is disposed outside the case main body 81 and communicated with the water tank 82. Water in the water tank 82 is sucked up by the supply pump 86 and is passed through the water conduits 85 and 84. In the first chamber 81A, the three nozzles 10 are injected and injected upward.
In addition, a blower 87 is provided in a part of the upper portion of the case body 81, and a blower duct 88 is provided in the upper portion of the second chamber 81B at a position opposite to the blower 87.

Here, a general evaporative cooler can immerse a drum with a honeycomb surface area with a large surface area in water and wet the surface and apply wind to it, or immerse a cloth or non-woven fabric with a high water supply rate in water. The temperature of the water is lowered by the heat of vaporization of the water, such as by blowing wind, and the heat of the air is taken away to lower the air to near the wet bulb temperature.
If the scale is small, the ratio of the surface area to the volume is large and the design is easy. However, as the scale is increased, the ratio of the surface area to the volume becomes relatively small, so there is a limit to the increase in size. Moreover, since the substance dissolved in water remains on the evaporation surface, it is necessary to periodically clean or replace the evaporation surface.

On the other hand, in the blower type cool air blower that uses the nozzle to randomly discharge water droplets into the indoor space, obtains contact with the air, evaporates, and takes away the heat of vaporization, the size of the room increases. However, since the water droplet density per space can be kept constant and the surface area is the sum of the surface of the water droplets, the problem of the ratio of the surface area to the volume that restricts general machines does not occur.
Further, the evaporation surface is a surface of a water droplet, and by selecting the particle size of the water droplet, it can be completely evaporated by receiving the wind of the blower 87, or it can get out of the case body 81 by riding on the wind. It can also be avoided.
Further, unlike the conventional method, a complicated mechanism such as a mechanism for driving or replacing the drum type evaporator is not required.
Further, when the upper portion of the case body 81 is formed of a transparent material, it can be enjoyed by watching the nozzle 10 scatter water droplets like rain.

[Application 2]
Next, an application example 2 of the fluid injection stirring apparatus according to the present invention will be described with reference to FIGS.

That is, in this cleaning gun 70, the nozzle 10 is attached to the tip of a pipe-like long arm 71 via a roll base 72, a handle portion 73 is provided at the base end of the long arm 71, and the handle portion 73 is further provided. The high-pressure hose 74, the faucet lever 75, and the roll base handle 76 that communicate with the long arm 71 via the head are provided. The roll table 72 can change the direction of the nozzle 10 by turning a roll table handle 76. In addition, a flow rate control valve (not shown) that controls the flow rate of water from the high-pressure hose 74 is provided in the vicinity of the handle portion 73.
Then, there is an effect that water or a cleaning water mixed with a cleaning liquid is injected and sprinkled from the nozzle 10 to perform, for example, cleaning of a high part.

Further, as shown in FIG. 15, the long arm 71 is constituted by a first arm 71A and a second arm 71B via a joint portion 78, and an arm joint operation handle 77 is provided on the handle portion 73. By operating this arm joint operation handle 77, the arm 71 is bent, so that, for example, in a complicatedly shaped part, for example, a blind spot on the upper side of a high place such as a bridge girder, or a blind spot on the lower side. The part can be cleaned.
In addition, the valve which controls the flow volume of water is provided in the vicinity of the handle part 73 (not shown).

  Here, the conventional cleaning nozzle has a fixed nozzle ejection direction, and is made for the purpose of directing the nozzle toward the portion to be cleaned. Therefore, the tip of a barrel-shaped rod was a spout for a so-called gun-type handle.

On the other hand, in the cleaning gun 70 of this application example 2, since the nozzle 10 ejects water and the like while irregularly vibrating, it is possible to eject fluid over a wide range with the nozzle center as the central axis. The nozzle 10 may be generally oriented in the direction in which water or the like is desired. Then, the jet can reach the blind spot.
Further, by bending the arm 71B ahead of the handle 73, the range in which the nozzle 10 is directed can be expanded. For example, the cleaning liquid can be sprayed from the floor surface to the back side of the overhanging floor and the like to be cleaned. effective.

[Application Example 3]
Next, an application example 3 of the fluid injection stirring apparatus according to the present invention will be described with reference to FIG.

  That is, the fine powder spraying device 90 includes a container 91 for storing powder, an ejector mixer 92 provided at one end of the container 91, the flexible nozzle 10 connected to the ejector mixer 92, and a container. 91, an air pump 93 connected to the air pump 93, a battery built-in handle 94 attached to the air pump 93, and an operating switch 95 provided in the handle 94.

When the switch 95 is turned on, the powder in the container 91 is pulverized into a fine powder state by the ejector mixer 92, and at the same time, the fine powder is sprayed from the flexible nozzle 10A to a predetermined position in the air. It has become.
That is, the shape of the guide fin portion 10c of the flexible nozzle 10 used in each of the above-described embodiments, etc. is changed to the guide fin of the flexible nozzle 10A as shown in FIG. The portion 10 cc is largely formed in a substantially fan shape.
Thereby, in the fluid injection stirring apparatus 1H of this application example 3, since the forward wave motion of the flexible nozzle 10A works in the same manner as a fan, it is possible to generate air by greatly stirring air.
Therefore, when the fine powder is ejected from the flexible nozzle 10, the fine powder is uniformly dispersed at a predetermined position by the self-excited vibration of the flexible nozzle 10.

Here, for example, in sake brewing, there is a process of sprinkling yeast on steamed raw rice, but it is difficult to evenly sprinkle, and it is said that a considerable season is necessary to be able to sprinkle evenly. It has been broken.
Also, for example, even in the operation of spraying uniformly with a spray gun for painting, it is necessary to change the spraying direction uniformly while frequently shaking the spray gun, and it is difficult to finish uniformly by simply spraying the coating liquid.
In the present embodiment, the present invention can also be applied to each operation as described above.

  As described above, the present invention has been described with reference to each embodiment and each application example, but the present invention is not limited to each embodiment and each application example. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention. Further, the present invention includes a combination of some or all of the configurations of the above-described embodiments as appropriate.

For example, in the first embodiment, the nozzle 10 includes the guide fin portion 10c and the flexible tube portion 10d.

Furthermore, although not shown in FIG. 18, the tube 80 has an inner diameter dimension and a length capable of jetting water or air supplied from the fluid supply device 41 and sufficiently stirring water such as lakes and ponds. What is necessary is just to use. For example, the dimensions of the tube 80 may be formed so that the inner diameter dimension is substantially the same as the inner diameter dimension of the flexible tube portion 10d, for example, 1 mm and the outer diameter dimension is, for example, 2 mm. The tube 80 is also preferably formed of silicon rubber.
Further, the inner diameter, outer diameter, length, etc. of the tube should be selected according to the viscosity and density of the fluid 1 and fluid 2 and the properties of the mixture. For example, when used for the fine powder spraying device 90 of the application example 3, Depending on the particle size of the powder, the inner diameter may be slightly increased to make it difficult for the powder to clog the discharge pipe 96.

Furthermore, the fluid injection and agitation device of the present invention can also be used when injecting a disinfectant solution when replacing water in a pool.
That is, although not shown, the fluid injection and agitation device is connected to, for example, the tip of the fluid hose to the nozzle on the nozzle holding body side that holds one nozzle, and the fluid hose is connected to the tap of the water supply on the pool side. The nozzle holder is installed in the vicinity of the outlet of the circulation pump of the pool.
Then, when the tap water is fed into the nozzle through the fluid hose, the flexible tube portion of the nozzle swings irregularly and agitates the water near the outlet of the circulation pump. Thereby, the thrown-in disinfectant can be stirred quickly and efficiently.

In the first to sixth embodiments, water or air as a fluid is injected into water (liquid) as a fluid and diffused and stirred. In the application examples 1 and 2, in the air Water as a fluid is injected and diffused. In Application Example 3, fine powder is ejected into the air by air pressure, but the method of using the flexible nozzle is not limited to this.
For example, it may be used as a method of injecting gas into the air, such as an example in which an aromatic gas is sprayed into a room or an example in which a sterilizing gas is injected into a sterilization chamber.

  The fluid injection and agitation apparatus of the present invention can be used when, for example, it is desired to efficiently agitate two or more kinds of fluids.
