Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention utilizes fluid energy to improve fluid flow channels such as waterways and rivers for cooling and irradiation, or intake and exhaust ducts. This relates to a mobile device that operates six shifts.

[Prior Art] In channels through which fluid flows, such as waterways or rivers for cooling or storage, or intake/exhaust ducts, there are devices for cleaning the inside of the channels or for transporting objects. is necessary.

For example, in power plant 1 petroleum complex, liquefied gas terminal, etc., waterways are installed to introduce seawater for various purposes such as cooling, but along with seawater, large amounts of shellfish, shellfish eggs, etc. are carried in these waterways. Inflow. As a result, a problem arises in that shellfish, shellfish eggs, etc. adhere to and accumulate on the side walls of the waterway.

Conventionally, the following methods have been used to remove shellfish adhering to the side walls of waterways.

(a) A floating structure such as a small boat equipped with an electric wire brush is placed in a waterway, the wire brush is brought into contact with the side wall of the waterway, and the floating structure is placed without rotating. Remove shellfish adhering to the side wall using a wire brush.

(b) Kill shellfish adhering to the side walls using chemicals such as hypochlorous acid.

[Problems to be Solved by the Invention] However, in the method (a) of removing the floating structure using an electric wire brush, a power source is required to move the floating structure along the waterway while rotating the wire brush. However, there are problems in that the device is complicated and requires a large amount of cost and labor.

On the other hand, in the method (b) of killing shellfish using chemicals, the chemicals dissolve in the seawater in the waterway, causing problems in the treatment of the seawater after use.

In addition to cleaning the side walls of waterways, it can also be used, for example, when transporting items from downstream to upstream, from upstream to downstream, or across a river, or when cleaning the inner walls of intake and exhaust ducts, chimneys, etc. It would be convenient if there was a device that could move within the flow path, but conventionally an engine or electric motor was provided as the power source, which made the device complicated and difficult to use, and the operating costs were high. was there.

This invention has been made in view of the above, and aims to provide a simple moving device that can move through a flow path without requiring a power source such as an engine or an electric motor. .

[Means for Solving the Problems] In the present invention, there is provided a fixed cable stretched in a flow path through which a fluid flows, a base body movable along the fixed cable, and a base member that is pivotally supported by the base body and that allows the fluid to flow. A movement comprising an impeller that rotates due to the flow, and a rotating body that rotates by the rotational force of the impeller and moves the base body relatively in the longitudinal direction of the fixed cable by cooperating with the fixed cable without slipping. The device achieves the above objectives.

Specific examples of the fixed rope in the present invention include ropes, chains, racks, and the like. To tension these cables in the flow channel, both ends of the cables may be fixed to the flow channel, or one end may be fixed to the flow channel and the other end may be supported by the moving device itself to generate tension. Good). Alternatively, a parachute or the like may be provided on the downstream side to apply tension by the flow of fluid. In addition, in this specification, the term "stretching" is used as a concept that also includes the case where a rack is laid on the bottom surface of a flow path.

The rotating body that cooperates with the fixed cable without slipping and rotates the base body relative to the fixed cable in the longitudinal direction may be a pulley (adhesive drive) or a sprocket (meshing drive), which is a combination of the fixed cable and the rotating body. The combination may be selected as appropriate, but when moving the base along a curved path, it is preferable that the fixed cable and the rotary body are configured to work together through meshing and driving.

In addition, when moving the base body in a direction that intersects the flow of fluid, for example, when moving across the flow, it is sufficient to use a bevel gear or the like so that the rotation axis of the impeller and the rotation axis of the rotating body are perpendicular to each other. .

[Effect] The principle of the present invention will be explained using the drawings.

First, FIG. 1 is a conceptual diagram of driving a moving device according to a first embodiment, which will be described later.

In the figure, a shaft 5 is rotatably supported by a base (not shown) floating in a waterway, and an impeller 6 and a pulley 7 as a rotating body are fixed to the shaft 5. Further, a rope 9 serving as a fixed rope is stretched between the upstream end and the downstream end of the waterway, and extends from the bottom to the top of the pulley 7 (below the pulley 7 and extending toward the upstream and downstream sides). ) is wrapped around.

In the moving device configured in this way, when the fluid (liquid in this case) is flowing in the direction of the white arrow, the impeller 6
rotates in the direction of arrow A with the shaft 5 as the rotation axis due to the flow. As a result, the impeller 6 and coaxial (shaft 5
) is fixed to the impeller 6 as shown by arrow B.
rotate in the same direction.

Then, a frictional force is generated between the pulley 7 and the rope 9 wound around the pulley 7, and the pulley 7 moves in the direction of the black arrow on the rope 9 due to the adhesive drive.

That is, so that the frictional force generated between the pulley 7 and the rope 9 exceeds the force necessary to move the base body from downstream to upstream.
If you set the rotational force of the boulif and the tension of the rope 9 (
For example, when the rope 9 is slack, the pulley 7 spins idly and does not move on the rope), and the base body can be moved from downstream to upstream in the waterway using only fluid energy as a power source.

Next, FIG. 2 is a conceptual diagram of the drive when a sprocket 27 is used instead of the pulley 7 (rotating body) of the moving device shown in FIG. 1, and a chain 29 is used instead of the rope 9 (fixed rope). .

In the figure, a chain 29 is stretched between the upstream and downstream ends of the waterway, and when the impeller 6 rotates due to the water flow in the direction of the white arrow, the sprocket 27 fixed on the same axis (shaft 5) also rotates. The sprocket 27 moves in the direction of the black arrow on the chain 29 by meshing drive. In this case, it does not depend on frictional force, so
There is no problem such as slippage of the rotating body, and rotational motion can be reliably converted into linear motion.

Note that even when a rack is used instead of the chain 29 as the fixed rope, the sprocket 27 and the rack work together by meshing and driving as in the case of FIG.
The substrate can be moved from downstream to upstream.

[Example] Example: 1 A first example of the present invention will be described using FIGS. 3 to 7. FIG. 3 is a schematic plan view of the moving device according to this embodiment;
Figure 4 is a schematic side view, Figure 5 is an enlarged plan view of the driving part,
FIG. 6 is a longitudinal sectional view of a waterway in which the moving device of this embodiment is arranged.

As shown in the drawing, the device of this embodiment has two floats 3 (substrates) that float in a waterway l provided for introducing seawater into a power plant, etc., and are provided parallel to the side wall 2 of the waterway l. It consists of a floating structure 4 with Two shafts 5 extending between the floats 3 are rotatably supported at the front and rear portions of the two floats 3 about their axes.

Each of the shafts 5 has a shaft 2 whose central axis passes through the shaft 5 and rotates by the flow of seawater flowing in the waterway 1.
Two waterwheels 6 (impellers) are fixed at a predetermined interval from each other.

Further, a pulley 7 is fixed between the two water turbines 6 on the shaft 5. A rope 9, whose both ends are supported by support mechanisms 18 installed on the ground at both longitudinal ends of the waterway 1, is connected to the pulley 7 from bottom to top, as shown in the plan view of the pulley 7 in FIG. The hook is being turned.

18a is provided on each or one of the support mechanisms 18,
This is a counterweight for applying a predetermined tension to the rope 9.

Water channels 1 are provided on both sides of the front and rear parts of the floating structure 4.
Four brushes 11 that contact both side walls 2 of the brush 11 are rotatably provided perpendicularly to a vertical central axis 12. Reference numeral 13 denotes a horizontal member horizontally suspended in the width direction of the water channel 1 between the upper parts of the central shaft 12, and a roller 14 for guiding and supporting the rope 9 is rotatably attached to the center of the horizontal member 13. There is.

As shown in FIG. 5, the shaft 5 consists of a pulley-side shaft 5a and a water-wheel-side shaft 5b, which are connected by clutch mechanisms 15 provided on both sides of the pulley 7. Therefore, by switching the clutch mechanism 15,
The direction of rotation of the pulley-side shaft 5a by the water wheel 6 can be changed.

When the floating structure 4 (moving device) as described above is floated in the waterway 1 with the four brushes 11 in contact with both side walls 2 of the waterway 1, the seawater flowing in the waterway 1 (in the direction of the white arrow) ) causes the water wheel 6 to rotate. As the waterwheel 6 rotates, the pulley 7 fixed to the shaft 5 rotates while rotating the rope 9. (Thus, the floating structure 4 moves in the waterway 1 from the downstream side to the upstream side due to the rotation of the water wheel 6 caused by the water flow), and the four floating structures contacting the side walls 2 move in the direction of the black arrow. The brush 11 removes shellfish, shellfish eggs, etc. adhering to both side walls.

The floating structure 4 moving in the waterway works by hooking and turning the rope 9 provided with a predetermined tension in the length direction of the waterway 1 (the pulley 7 and the rope 9 work together by adhesive drive), and It moves eight times while being guided by brushes 11 that are in contact with both side walls.

Therefore, the floating structure 4 can move smoothly in the waterway 1 without causing sideways vibration and without the pulley 7 slipping on the rope 9.

As described above, when the floating structure 4 reaches a predetermined position near the upstream end in the waterway 1, the clutch mechanism 15 provided on the shaft 5 is switched (for example, manually) to rotate the pulley-side shaft 5a. Convert direction. As a result, the floating structure 4 moves in the waterway l from the upstream side to the downstream side, and is attached to both side walls 2 by the four brushes 11 that contact the both side walls 2, as described above. Shellfish.

Shell eggs etc. are removed.

In the example described above, shaft 5. The water wheel 6 and pulley 7 are
Although two sets are provided in the floating structure 4, one set of these may be provided. Further, the number of brushes 11 is not limited to four, but two may be provided, and the water wheel 6 and brushes 11 can be replaced with more efficient ones at any time.

If the mobile device of this embodiment as explained above is used,
To efficiently and properly remove shellfish adhering to the side wall of a waterway, especially shellfish eggs with weak adhesion, by means of a reciprocating motion using water flow, using a simple device that does not require a power source other than water flow energy. Can be done.

Example: 2 A second example of the present invention will be described using FIGS. 8 to 10. FIG. 8 is a schematic plan view of the moving device according to this embodiment;
FIG. 9 is a schematic side view, and FIG. 10 is a longitudinal sectional view of a waterway in which the moving device of this embodiment is arranged.

Similar to the first embodiment, the moving device of this embodiment is a moving device that is used to clean the side wall of the water channel 1, and is configured to automatically reciprocate.

The moving device (floating structure 4) of this embodiment has two floats 3 arranged parallel to the side wall of a waterway 1, and guide rolls 16 are provided on both sides of the front and rear parts of the floats 3, respectively. At the same time, a brush support 15 is provided in the vertical direction approximately in the center of the float 3, and a brush support 15 is provided in a vertical direction to support the brush 11
is installed.

Further, a shaft 5 is rotatably supported between the two floats, and two water turbines 6 are each fixed to the shaft 5 at a predetermined interval.

A sprocket 10 is fixed between both water turbines 6.

In this embodiment, the pulley 7 (rotating body) is provided apart from the shaft 5 to which the water wheel is fixed.
A power transmission means including a clutch mechanism 8a (described later) is provided between the sprocket 10 and the sprocket 10 fixed to the shaft 5, and a chain 12 is hooked and rotated between the sprocket 10 and the sprocket on the clutch mechanism 8 side. .

On the other hand, the rope 9 serving as a fixed cable has one end fixed to a support mechanism 18 installed on the ground at the upstream end of the waterway 1, and is attached to a pulley 7 provided on the floating structure 4 in the same manner as explained in FIG. It's wrapped around.

In this embodiment, a parachute 13 is provided at the downstream end of the rope 9, and the rope 9 is
Tension is applied to the Also, rope 9
Clutch switching pieces 17 (described later) are fixed at predetermined positions on the upstream and downstream sides of the clutch.

When the moving device (floating structure 4) of this embodiment configured as described above is floated in the waterway l, the water flow (in the direction of the white arrow) causes the water wheel 6 to rotate clockwise in the figure, coaxially (shaft 5
) is also rotated in the same direction as the water wheel 6. The rotation of the sprocket 10 is then transmitted to the clutch mechanism 8 by the chain 12.

Here, the clutch mechanism 8 used in this embodiment is configured as follows, for example.

Rotation where the rotation of the water turbine 6 is transmitted via the chain 12 @
, (driving shaft) and the rotating shaft (driven shaft) of pulley 7,
A gear mechanism that transmits the rotation of the driving shaft without changing the direction of rotation, and a gear mechanism that transmits the rotation direction while reversing the rotation direction are provided, and one of the two sets of gear mechanisms is selectively connected between both rotating shafts. Keep it. A clutch switching lever (not shown) for operating a gear selection means for fixing the idling gear to the rotating shaft is provided at a position facing the clutch switching piece 17 of the rope 9.
The gears connected to each other may be switched by the impact force when the lever collides with the lever.

As shown in FIG. 8, when moving from the downstream to the upstream of the waterway 1, the clutch mechanism 8a is connected to the gear mechanism that transmits the rotation without changing the direction of rotation, and the pulley 7 It rotates in the same direction as the waterwheel 6 and works in cooperation with the rope 9 by adhesive drive. As a result, the floating structure 4
moves in the direction of the black arrow.

Then, when the floating structure 4 approaches the upstream end of the waterway 1 and the clutch switching lever collides with the clutch switching piece 17 fixed to the rope 9, the clutch mechanism 8a is switched as described above.

That is, the rotation direction of the water turbine is reversed by the clutch mechanism 8a and transmitted to the pulley 7, and the floating structure 4 moves from upstream to downstream (from the paper to the left).

When the floating structure 4 approaches the downstream end, the clutch switching lever collides with the clutch switching piece 17 on the downstream side,
As a result, the rotation direction of the pulley 7 becomes the same direction as the water wheel 6 again, and the pulley 7 moves upstream.

As described above, the moving device (floating structure 4) according to this embodiment can reciprocate in a predetermined section between the upstream end and the downstream end without requiring any power source other than water energy. The brush 11 can efficiently remove shellfish and dirt adhering to the side wall of the waterway.

Furthermore, in this embodiment, the guide roll 16 is provided on the outside of the float 3 via an extendable arm, so even if the width of the waterway is not exactly constant, sideways wobbling etc. do not occur, and the waterway is You can move 8 times along the line stably.

In the above example, the clutch switching piece 17 is attached to the rope 9, but it goes without saying that it may be fixed to the bottom of the waterway or the like (the height may be adjusted as appropriate with a fixing member or the like).

Example: 3 A third example of the present invention will be described using FIG. 11. 1st
FIG. 1(a) is a schematic front view of the moving device according to this embodiment, and FIG. 11(b) is a schematic plan view.

The moving device of this embodiment is configured to travel on land using water currents, and is useful, for example, when transporting items along a relatively narrow waterway or scraping up sludge from the bottom of a waterway. used.

In the figure, the shaft 15a and the shaft 15b are each provided with wheels 23 at both ends, and the rack is spanned in the width direction of the waterway 1. Both shafts 15a, 15b
are rotatably connected by a connecting member 23a (corresponding to the base body), and two water turbines 6 are connected to the shafts 15a and 15b, respectively.
Each is fixed. The height of the water wheel 6 (that is, the diameter of the wheel 23) is set such that the lower part of the water wheel 6 is immersed in the water surface by a predetermined amount. In addition, 2 of the shaft 15a on the upstream side
A pulley 7 is fixed between the two water wheels 60, and a winding drum 20 having a slightly larger diameter than the pulley 7 is fixed between the two water wheels 6 on the shaft 15b on the downstream side.

In this embodiment, the rope 9 has one end fixed to the upstream end of the waterway l, is wound around the pulley 7 from bottom to top as shown in the figure, and the other end is attached to the winding drum 20.
is wrapped around.

In the moving device having such a configuration, the water wheel 6 is rotated by the water flow (in the direction of the white arrow), and the pulley 7 is rotated accordingly.
The winding drum 20 rotates in the same direction.

The conditions for the winding drum 20 in this embodiment are: l) The diameter is equal to or larger than the diameter of the pulley 7.

2) The rotation speed can be changed while maintaining a predetermined tension (the rope 9 is attached to the take-up drum 20)
When more than one layer is wound, the peripheral winding speed increases and pulley 7
slips. ), an example of such a winding drum 20 is a friction drum as shown in FIG. 11(c).

In the figure, a sliding portion 20b is provided on the inner peripheral surface of the drum 20, and this sliding portion 61 (20b is supported by springs 20a arranged radially.
Since the rotational speed of the drum 20 is reduced by the friction generated between the inner circumferential surface of the drum 20 and the sliding part 20b, the pulley 7 does not slip and the rope 9 is driven by adhesive.
(The moving device moves in the direction of the black arrow while rotating the rope 9 in cooperation with the moving device.) As a result, the moving device moves from downstream to upstream.

When using the moving device of this example for transportation, for example,
It is advisable to provide a loading platform (not shown) on the connecting member 23a so as not to interfere with the rotation of the water wheel, etc. In addition, for example, a scraper (not shown) may be installed on the connecting member 23a to use it for cleaning waterways.
If it is fixed to the waterway and placed close to and parallel to the bottom of the waterway, relatively soft sludge, etc. on the bottom can be collected.

Furthermore, the moving device of this embodiment can also be used for purposes such as spraying chemical solutions along waterways.

Example=4 A fourth example of the present invention will be described using FIG. 12. 1st
FIG. 2 is a schematic plan view of a waterway in which the moving device of this embodiment is arranged.

The moving device of this embodiment has a pair of floats 3 floating on the water surface as a base, and a shaft 5 pivotally supported between the floats 3.
The configuration in which two water turbines 6 are fixed to is shown in Examples 1 and 2.
is similar, but waterway 1 is not a straight road but an oil road,
A sprocket 27 is fixed to the shaft 5 instead of a pulley as a rotating body. Moreover, as a fixed cable, instead of a rope, a rack 29a (the teeth cut into the rack are omitted in the figure) is laid at a height that meshes with the sprocket 27. Further, a guide roller 16 is provided on the outside of the float 3 via a spring.

In the moving device having such a configuration, the water wheel 6 rotates due to the water flow (in the direction of the white arrow), and the sprocket 27 fixed on the same axis also rotates in the same direction. Then, the sprocket 27 moves on the rack in the direction of the black arrow by meshing drive while rotating, and the moving device moves from downstream to upstream along the oil path. At this time, since the guide roll 16 is in a state of pressing the side surface of the water channel 1, the sprocket 27 does not come off the rack. Also,
Even if there are some irregularities on the side wall of the water channel, the guide roll 16 can be moved without any trouble due to the buffering action of the spring supporting the guide roll 16.

The moving device of this embodiment as described above can be used for transportation and cleaning of waterway walls as well as for example, by attaching a mesh bag to the rear of the moving device and cleaning dead leaves floating on the water surface. You can also collect garbage.

In the above example, a rack was provided as the fixed cable, but it goes without saying that a chain may also be used. In addition, if the curve of the oil passage is gentle, provide appropriate guide means such as the aforementioned guide roll with a spring, and
By adjusting the tension appropriately, a combination of pulley and rope can also be used.

Example=5 A fifth example of the present invention will be described using FIG. 13. 1st

Further, the shaft 25b is arranged parallel to the direction of the water flow (orthogonal to the shaft 25a),
A bevel gear 10b is attached to the end of the shaft 25a.
It is fixed so that it meshes with a. The other end of the shaft 25b is rotatably supported by a bearing 10c, and a pulley 7 is fixed approximately at the center of the shaft 25b.

In this embodiment, a rope 9 is stretched as a fixed cable in the width direction of the river (both ends of the rope 9 are fixed to the shore), and is wound around the pulley 7 from bottom to top.

In the moving device configured in this way, the water flow causes the water wheel 6 to rotate in the direction of arrow A about the shaft 25a, and this rotation is transmitted to the shaft 25b via the bevel gears 10a and 10b. The fixed pulley 7 rotates in the direction of arrow B. As a result, the pulley 7 is moved by adhesive drive in the direction perpendicular to the direction of the water flow (in the direction of the black arrow) while rotating the rope 9. In this way, the mobile device of this embodiment can cross the river using the river flow.

It goes without saying that a sprocket and a chain (or rack) may be used instead of the pulley 7 and rope 9.

Example=6 A sixth example of the present invention will be described using FIG. 14. 1st

A bevel gear 30d that meshes with the bevel gear 30C is fixed to the end on the shaft 35b side, and a pulley 7 is fixed to the substantially central part. It passes through the duct 22 and extends substantially on the center line of the duct 22, and is wound around the pulley 7.

In the moving device configured in this way, the shaft 35a rotates in the direction of arrow A as the propeller 26 rotates due to the airflow (in the direction of the white arrow), and this rotation is transmitted to the shaft via spur gears 30a and 30b. 35b, and the shaft 35b rotates in the opposite direction (arrow B) to the shaft 35a. Further, the rotation of the shaft 35b is transmitted to the shaft 35c via the bevel gears 30C and 30d, and the pulley 7 rotates in the direction of arrow C while rotating the rope 9. As a result, the moving device moves along the duct 22 in the direction of the black arrow. At this time, since the shaft 35a is supported from three directions by the wheels 36, the device will not wobble sideways.

When used in the above-mentioned device, for example, the inner wall of the duct can be easily cleaned by attaching a brush, puff, etc. to the base (not shown).Since the moving device of the present invention is not electric, Safe even when flammable gas is flowing.

In the figure, the duct 22 is piped horizontally, but it goes without saying that if the weight of the moving device is appropriately set, it can be similarly applied to cases where the flow path is provided vertically, such as in a chimney. stomach.

Embodiment 7 A seventh embodiment of the present invention will be described with reference to FIG. 1st
