Description

  The present invention relates to an environmental purification device that purifies water such as lakes.

  In recent years, in lakes and marshes, deterioration of water quality and the generation of odors associated therewith have become a problem.

  The main cause of this problem is the accumulation of water in the lake, resulting in the growth of anaerobic bacteria and abnormal occurrence of hydrangea (blue water etc.), causing bad odors and water quality deterioration to serious aquatic animals and plants. Doing damage.

  In order to prevent such problems, conventionally, forced oxygen is forced to circulate with a pump, water is circulated with a water turbine, or air is blown into water (hereinafter referred to as aeration). Or increased it.

  In the method of forced water circulation with a pump, the power is large and there is a concern about sludge clogging associated with sucking up the water at the bottom of the lake, so complicated maintenance must be borne by the user side. .

  The method of circulating water using a water wheel is as powerful as using a pump. In addition, since it can only be stirred near the coast, it must be installed at multiple locations around the target lake to obtain a sufficient effect. As a result, more power sources are required and the usage cost increases.

  Also in the case of the aeration method, the power for ejecting air is large. In addition, this method only sends oxygen into the water, so the stirring effect of the entire lake is small. Further, since the jet power is changed to propulsive force, the device must be fixed on land, and only a local effect can be obtained.

  Since all of the above-described methods require large power, power consumption becomes a problem. In order to solve the problem of power consumption in these systems, a floating energy-saving water purifier that prevents stagnation of water with small electric power has been proposed (for example, see Patent Document 1).

  FIG. 19 is a cross-sectional view of the floating type energy-saving water purifier proposed in Patent Document 1 as seen from the side when floating.

  This floating energy-saving water purifier floats on the water surface 101 of the pond by the float 103, and slowly rotates the floating blade 104 with the float by the motor 102.

  In FIG. 20, the figure which looked at the current-flow blade 104 with the float from the bottom is shown.

  In FIG. 19 and FIG. 20, the flow of water in water generated by the floating energy-saving water purifier is indicated by white arrows.

  As shown in FIG. 20, the floating blade 104 with the float is provided with four blades 107 extending in the radial direction from the rotating shaft 108 of the motor 102 toward the outer periphery so as to be a surface perpendicular to the water surface 101. It has been.

  As the floated current blade 104 rotates slowly, a flow of water flowing radially from the center of the rotation is created on the water surface. As shown by the white arrow in FIG. 19, the flow is brought into contact with air to take in oxygen, change the direction downward while receiving the sun's light, and flow so as to crawl the bottom 106 and return to the center of the original rotation. Return, rise again and repeat the circulation.

  In order to make the water transparent, a microbial filtration mat 105 is provided in the water flow field.

Japanese Patent No. 3360075

  However, the above-described conventional floating energy-saving water purifier cannot sufficiently obtain the effect of preventing water retention when used in a large area such as a dam or a large lake where the water depth is deep and the target area is large.

  19 and 20, when the water depth is shallow and the target area is small, the water flow does not disappear and the effect of preventing water retention is exhibited by the water circulation. . However, since this floating energy-saving water purifier uses the pumping effect generated by pushing water on the surface sideways, when the force to pump water is small, the water depth is deep and the target area is wide, The flow is weak and the effect of preventing sufficient retention of water cannot be exhibited.

  Moreover, as a method for purifying lakes and marshes, there is a method of sending bacteria that decompose and remove harmful substances and sludge from the bottom of the water, but conventional floating energy-saving water purifiers cannot send such bacteria to the bottom of the water.

  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
FIG. 1A is a side view schematically showing a state in which the environment purification apparatus according to the first embodiment of the present invention is floated on a dam to be purified.

  The environmental purification device 10 according to the first embodiment is used by being suspended in a dam or a lake, and is moored by an anchor or the like installed on the bottom of the water so as not to be washed away from the place where it is installed to the coast. However, in FIG. 1A, illustration of a member for mooring is omitted.

  The main body 11 of the environmental purification apparatus 10 includes a motor 12, a battery 13, a gear box 14, a rotating shaft 16, and a plurality of float balls 18. The motor 12, the battery 13, and the gear box 14 include a lid 15. Sealed and waterproof.

  FIG. 1B shows a top view of the main body 11 with the lid 15 removed.

  The float ball 18 is a spherical member having buoyancy with respect to water, and is arranged in a ring shape at the lower part of the main body 11 as shown in FIGS. By arranging the plurality of float balls 18 in a ring shape in this way, the main body 11 can float on the water surface stably without being turned over by wind or waves.

  As the float ball 18, for example, a foamed polystyrene or a sealed hollow ball can be used.

  The motor 12 is driven by the electric power of the battery 13, and the rotation speed and the rotation direction of the motor 12 are appropriately converted by the gear box 14, and the rotation shaft 16 protruding in the vertical direction from the center of the lower surface of the main body 11 is slowly moved. Rotate. In addition, when the test by the actual machine was performed, even when the rotating shaft 16 was rotated at a slow speed of about 7 to 30 rpm, it was confirmed that the effect of preventing water retention was sufficiently exhibited.

  A screw-shaped blade 17 having a propulsive force used in a ship or the like is attached to a tip portion of the rotating shaft 16 protruding downward from the main body 11 and rotates together with the rotating shaft 16.

  The rotating shaft 16 can rotate in both forward and reverse directions, and sucks up or propels water below the blade 17 depending on the direction of rotation of the blade 17.

  The white arrow in FIG. 1A indicates the flow of water generated by the rotation of the blade 17. As shown in FIG. 1A, an upward or downward flow of water is generated between the blade 17 and the bottom of the water depending on the rotation direction of the blade 17.

  Since the environmental purification apparatus 10 according to the first embodiment is provided with screw-shaped blades 17 in a direction in which propulsive force is generated in the vertical direction, the pumping of water by a tornado rotation from a deep water location by rotating the blades 17. An action occurs, and a flow of water from the bottom to the surface of the water occurs.

  The water pumped up near the bottom of the water is in contact with the air while diffusing radially from the environmental purification device 10 on the surface of the water, increasing the amount of dissolved oxygen. By increasing the amount of dissolved oxygen, the growth of aerobic bacteria living in the lake is promoted, and the growth of anaerobic bacteria can be suppressed. And by suppressing the growth of anaerobic bacteria, it is also possible to suppress the generation of methane, which is the main cause of malodor.

  When the suspended matter which becomes the source of turbidity is uniformly dispersed by pumping up according to the rotation of the blades 17 and the diffusion effect, the suspended matter, sludge and the like become a nucleus and a small lump (floc) is formed. This floc becomes the home of microorganisms and eventually disappears as food for fish. This effect promotes purification of water, and the activity of aerobic bacteria can be further activated by more sunlight reaching the water.

  As described above, the environment purification apparatus 10 according to the first embodiment realizes agitation of a wide range of water by adopting a system in which deeper water is pumped up by tornado rotation. Since the tornado rotation is caused from the center of the environmental purification device 10, the bottom agitation effect is high, and more water quality improvement effect than the conventional floating energy-saving water purifier as shown in FIG. Can bring.

  Therefore, the environmental purification apparatus 10 of the first embodiment can circulate water even in a dam or a large lake with a large target range, and can prevent water from staying.

  Moreover, the environmental purification apparatus 10 of this Embodiment 1 uses the float type which floats on water, and since the blade | wing 17 has only an up-and-down propulsion function, it can stir at a substantially fixed position.

  In addition, since it is a floating type, there is also an effect that the mobile installation can be easily performed.

  Further, since the driving force uses decelerated power (about 7 to 30 rpm), the driving force is high torque and low power.

  In addition, since a flow of water toward the bottom of the water can be generated, bacteria that decompose and remove harmful substances can be sent to the bottom of the water using the flow of water.

  Moreover, the main body part of the environmental purification apparatus according to the first embodiment is not limited to the shape as shown in FIG. 1, and may have any shape as long as it is a shape that stably floats on the water surface.

  FIG. 2 shows an example of another shape of the main body portion of the environmental purification apparatus according to the first embodiment. In FIG. 2, illustration of the blade portion is omitted.

  In the environment purification apparatus shown in FIG. 2, a main body portion is constituted by two parts, that is, a rotary power unit 19 and a float pipe 20 connected to the rotary power unit 19.

  The float pipe 20 has a hollow sealed pipe connected in a ring shape so as to surround the rotary power unit 19. By adopting such a structure, the float pipe 20 can float on the water surface stably.

  FIG. 3 shows a side view of another environment purification apparatus of the first embodiment having a configuration that effectively generates a flow of water diffusing on the water surface.

  The main body 26 of the environmental purification device 25 shown in FIG. 3 has a mortar shape in which the bottom 29 protrudes toward the blade 28 with the rotation shaft 27 as a vertex.

  When the screw-shaped blades 28 are rotated counterclockwise as viewed from below, a flow of water from the bottom of the water toward the blades 28 is generated. The flow of water going upward from the blades 28 progresses along the mortar-shaped bottom 29 by smoothly changing the direction radially from the portion of the rotating shaft 27.

  In the case of the main body part 11 of the environmental purification apparatus 10 shown in FIG. 1, the lower surface is a plane, so that the flow of water proceeds upward from the blades 17 and hits the lower surface of the main body part 11 perpendicularly and diffuses. In the case of the main body 26 shown in FIG. 3, the flow of water smoothly changes from the upward direction to the horizontal radial direction due to the shape of the bottom 29, so that the water surface is diffused more than in the case of FIG. The water flow becomes stronger.

  Since the bottom 29 has such a shape, the flow of water diffusing on the water surface can be strengthened, so that water can be circulated more effectively.

  FIG. 3 illustrates the case where the environmental purification device 25 sucks up water from the bottom of the water. FIG. 4 illustrates the case where the environmental purification device 25 illustrated in FIG. 3 propels water toward the bottom of the water. Yes.

  As shown in FIG. 4, when the screw-shaped blade 28 is rotated clockwise as viewed from below, a water flow from the blade 28 toward the bottom of the water is generated. The blade 28 sucks water above and propels it toward the bottom of the water, but the water on the surface of the water smoothly flows along the mortar-shaped bottom portion 29 toward the top of the blade 28, so that it is more effectively directed toward the bottom of the water. Can promote water.

  The case of the conical shape as shown in FIGS. 3 and 4 has been described as an example of the shape of the bottom portion of the main body for effectively circulating water, but other shapes may be used, for example, around the rotating shaft portion. The shape may be such that the side surface of the cone is curved toward.

  In the environmental purification device used in a suspended state as in the first embodiment, when the blade rotates, a reaction torque is generated by the rotation of the blade, and a rotational force opposite to the rotation direction of the blade acts on the main body. To do. For example, when the environmental purification device is moored with a plurality of ropes, when the main body rotates when the amount of water decreases and the water depth becomes shallow, there is a possibility that a plurality of loose ropes may get entangled.

  Therefore, it is desirable to suppress the rotational force on the main body generated by the rotation of the blades.

  In the environmental purification apparatus shown in FIG. 2, the side surface 21 of the lower portion of the rotary power unit 19 that is in contact with water has a shape in which box-shaped recesses are arranged. The partition plates of these adjacent box-shaped recesses on the side surface 21 of the lower part of the rotational power unit become resistance, and the rotational force generated in the main body by rotation of the blades is suppressed.

  Further, the bottom of the main body may be shaped such that a rotational force opposite to the rotational force generated by the reaction torque of the blade rotation acts on the main body using the flow of water generated by the blade rotation. .

  FIG. 5 shows a perspective view of the shape of the bottom portion of the main body that generates such rotational force using the flow of water.

  The shape of the bottom shown in FIG. 5 is such that when receiving a water flow toward the front of the bottom, depending on the angle of the step provided on the bottom, the main body is rotated counterclockwise around the rotation axis when viewed from the front. It is made into the shape which produces the force which rotates. That is, it is shaped so as to generate a force for rotating the main body in the same direction as the rotation direction of the blades 28 (in this case, counterclockwise when viewed from below).

  For example, in the environmental purification apparatus 25 as shown in FIG. 3, the shape of the bottom part may be a shape as shown in FIG.

  In the environmental purification device 25 shown in FIG. 3, when the blades 28 are rotated counterclockwise when viewed from below, a flow of water from the bottom of the water toward the blades 28 is generated. At this time, due to the reaction torque caused by the rotation of the blades 28, a force that rotates clockwise when viewed from below acts on the main body 26. On the other hand, the water sucked up from the bottom by the blades 28 flows upward from the blades 28 toward the bottom of the main body 26. Since the bottom portion has a shape as shown in FIG. 5, a force that rotates counterclockwise when viewed from below is generated in the main body portion 26 when the water flow directed upward from the blades 28 hits the bottom portion.

  Since the rotational force acting on the main body portion 26 due to the reaction torque caused by the rotation of the blades 28 and the direction of the rotational force generated in the main body portion 26 when the water flow hits the bottom portion, these rotational forces are offset, and the rotation of the blades It is possible to suppress the rotational force generated in the main body by the reaction torque.

  By changing the angle of the step shown in FIG. 5, the magnitude of the rotational force generated in the main body portion 26 by the water flow from the blades 28 toward the bottom can be adjusted.

  The shape of the bottom shown in FIG. 5 has been described by taking an example of a configuration in which a step is provided on a horizontal surface. However, a configuration in which a step as shown in FIG. 5 is provided on the conical side surface of the bottom 29 as shown in FIG. Good.

  In addition, since air has a smaller resistance than water, the volume of the portion of the main body that is in contact with the air is the same even when the rotational force acting on the main body is the same due to the reaction torque caused by the rotation of the blades. The larger the size, the easier it is for the main body to rotate.

  Therefore, by reducing the volume of the portion of the main body that is in contact with the air, the rotation of the main body due to the reaction torque caused by the rotation of the blades can be suppressed.

  FIG. 6 shows a side view of the environmental purification device in which the volume of the portion of the main body that is in contact with the air is reduced.

  The main body 30 of the environmental purification apparatus shown in FIG. 6 is adjusted to have buoyancy so that almost the entire main body 30 is in contact with water and floats. Therefore, the main body 30 is less likely to rotate due to the reaction torque caused by the rotation of the blades.

  However, in this case, since it is difficult to visually recognize the position of the environmental purification device from the surface of the water, as shown in FIG.

  Since it is only necessary to be able to confirm the position of the environmental purification device from a remote position on the water, not only the flag 31 but, for example, a stick is set up on the upper part of the main body 30, and the LED attached to the tip thereof blinks or lights up. Also good.

  Moreover, you may make it provide the structure which suppresses the rotational force which acts on a main-body part with the torque of the reaction by rotation of a blade | wing.

  FIG. 7A shows a side view of the environmental purification device in which a structure for suppressing the rotational force acting on the main body by the reaction torque caused by the rotation of the blades is added to the main body.

  Bars protruding to the periphery such that their tips are located in water are provided on the four sides of the main body 32, and a rotation suppression plate 33 is attached to the tips of these rod arms. The rotation suppression plate 33 is attached in a direction in which the surface thereof is perpendicular to the water surface so that the rotation of the main body 32 can be effectively suppressed.

  Moreover, you may attach the member which has not a plane but a bowl shape instead of the rotation suppression board 33 plate as a front-end | tip part of the stick | rod which suppresses rotation of a main-body part.

  FIG.7 (b) shows the side view of the environmental purification apparatus of the structure which suppressed the rotational force which acts on a main-body part with the torque of the reaction by rotation of a blade | wing with the hook-shaped member (rotation suppression collar part 37). .

  In addition, the structure which combined the stick | rod sticking out to the periphery from the main-body part 32, and the rotation suppression board 33 plate or the rotation suppression collar part 37 attached to the front-end | tip of the stick | rod of the peripheral attachment member of the main-body part of this invention. An example.

  Moreover, it is good also as a structure which suppresses more effectively the rotational force which acts on a main-body part with the torque of the reaction by rotation of a blade | wing.

  FIG. 8A shows a side view of an environmental purification device in which a main body portion is provided with a rotation suppression plate that rotates in a direction opposite to the blade.

  The main body 34 includes a second rotating shaft 35 that rotates in the opposite direction in the same direction as the rotating shaft 27 that rotates the blades 28, and the rotation is suppressed from the second rotating shaft 35 to the tips of a plurality of bars attached horizontally. A plate 36 is attached.

  In order to effectively cancel the rotational force acting on the main body by the reaction torque caused by the rotation of the blades 28, the rotation suppression plate 36 is attached in a direction in which the surface thereof is perpendicular to the water surface.

  FIG. 8B shows a side view of an environmental purification apparatus having a configuration in which a hook-shaped member is provided that rotates in the direction opposite to the blade and faces the recess in the rotating direction.

  The main body portion 34 in FIG. 8B is provided with a rotation suppression flange portion 38 having a hook shape so that the concave portion faces the rotation direction at the tip of the rod protruding from the second rotation shaft 35 to the periphery. Yes.

  Since the rotation of the main body 34 can be suppressed more efficiently than the planar rotation suppression plate 36 used in FIG. 8A, the rotation of the main body 34 can be suppressed with a smaller power than in the case of FIG. .

  In addition, the rotation suppression plate 36 or the rotation suppression collar part 38 attached to the 2nd rotating shaft 35 corresponds to an example of the 2nd blade | wing of this invention.

  The second rotating shaft 35 may be rotated by providing a motor different from the motor that rotates the rotating shaft 27, or the motor that rotates the rotating shaft 27 is commonly used, and the rotation direction depends on the gear structure. The second rotation shaft 35 may be rotated by changing the rotation speed.

  In addition, it is good also as a structure which combined 2 or more types of each structure shown in FIGS. 5-8 as a structure which suppresses the rotational force which acts on a main-body part with the torque of the reaction by rotation of the blade | wing 28. FIG.

  Moreover, since the environmental purification apparatus of this Embodiment 1 can be driven with low electric power, it can also utilize photovoltaic power generation.

  In FIG. 9, the cross-sectional schematic diagram of the environmental purification apparatus of this Embodiment 1 using solar power generation is shown.

  As shown in FIG. 9, a motor 41, a gear box 42, and a rechargeable battery 43 are provided in the main body 40, and a solar panel 44 is disposed on the upper surface. The motor 41 is driven by the electric power from the rechargeable battery 43 or the solar panel 44, the rotation direction and the rotation speed are converted by the gear box 42, and the rotation shaft 27 rotates.

  In the daytime, the motor 41 is driven by the power received by the solar panel 44 and the rechargeable battery 43 is charged. The motor 41 is driven by the power from the rechargeable battery 43 at night when sunlight is not received.

  With such a configuration, the environmental purification device can be operated for a long time without replacing the battery.

In the description of the first embodiment, the illustration and description of the structure for mooring the environmental purification device are omitted. However, the environmental purification device that is used in a suspended state is moored so that it is not carried away by the wind or waves on the coast. There is a need to. In Embodiment 2 of the present invention, a mooring method for an environmental purification apparatus will be described.

  When used in a pond with a narrow target area, it can be moored with a rope from the shore, but when used in a dam or large lake with a wide target area, the distance from the shore is too far. They will be moored by fixtures installed at the bottom of the water.

  FIG. 10 is a diagram for explaining a mooring method for the environmental purification apparatus according to the second embodiment. Here, it demonstrates using the environmental purification apparatus 25 shown in FIG. 3 and FIG. 4 as an example explaining a mooring method.

  Rope fasteners 45 are provided at a plurality of locations apart from each other on the side surface of the environmental purification device 25. And the anchor 46 is fixed to the location which was mutually separated on the water bottom, and each anchor 46 and each rope fastener 45 are connected with the rope 47. Here, although the anchor 46 is arrange | positioned in three places which left | separated, the anchor 46 should just be arrange | positioned in the position of 2 or more places away from the water bottom.

  The anchor 46 is an example of the fixture of the present invention, and the rope 47 connecting the environmental purification device 25 and the anchor 46 is an example of the locking member of the present invention. In this case, a chain or the like may be used in place of the rope 47 as the locking member of the present invention.

  The length of each rope 47 is adjusted to such a length that the environmental purification device 25 is not submerged even when the water surface rises due to rainfall or the like.

  The environmental purification device 25 may rotate its main body due to the influence of wind and waves, or the influence of reaction torque generated by the rotation of the blades. If the main body rotates when the water surface descends and the rope 47 is slack, each rope 47 gets tangled in the water.

  FIG. 11 illustrates a mooring method in which the rope 47 does not get tangled in water even when the main body rotates.

  As shown in FIG. 11, the environmental purification device 25 is connected to an anchor 46 fixedly installed on the bottom of the water by a single rope 47 connected to a rotatable fastening portion 48 at the tip portion of the rotating shaft 27.

  The rotatable fastening portion 48 has a fastening structure that allows the rope 47 to move freely with respect to the main body portion of the environmental purification device 25 and the rotary shaft 27.

  If the rope 47 has a fastening structure that does not move freely with respect to the main body of the environmental purification device 25, the rope 47 is twisted by the rotational force of the main body, and the substantial length of the rope 47 is shortened. This is because the environment purification device 25 cannot move freely on the water surface.

  FIGS. 12A to 12C show the tip portion of the rotating shaft 27 of the environmental purification device 25 of FIG. 11, and are specific examples of the structure of the rotatable fastening portion 48.

  In the structure shown in FIG. 12A, a free rotating shaft 50 coaxial with the rotating shaft 27 is provided inside the rotating shaft 27, and a rotating metal fitting 51 is connected to the tip of the free rotating shaft 50. The tip part of 47 is connected.

  The free rotating shaft 50 can be freely rotated with respect to the main body of the environmental purification device 25 and the rotating shaft 27. The rotating metal fitting 51 is connected to the free rotating shaft 50 by a rotating portion 52, and the rotating portion 52 is connected to the free rotating shaft 50 with a direction perpendicular to the rotation center of the free rotating shaft 50 as a rotation center. It is free to rotate.

  In the structure shown in FIG. 12B, a fixed shaft 53 that is coaxial with the rotary shaft 27 is provided inside the rotary shaft 27, and a rotating metal fitting 54 is connected to the tip of the fixed shaft 53. The tip part of is connected.

  The fixed shaft 53 is fixed to the main body, and does not rotate even if the rotary shaft 27 rotates. The rotating metal fitting 54 is connected to the fixed shaft 53 by the rotating portion 55, and has a spherical tip at the rotating portion 55, and the spherical portion is fitted to the tip portion of the fixed shaft 53. In the range below the fixed shaft 53, it is rotatable with respect to the fixed shaft 53.

  In addition, a rotatable metal fitting 56 is provided in a portion of the rope 47 connected to the rotation metal fitting 54 so that the tip portion of the rope 47 can freely rotate around the longitudinal direction of the rope 47. Yes.

  In the structure shown in FIG. 12C, the rotatable metal fitting 57 is connected to the distal end of the fixed shaft 53, and the distal end portion of the rope 47 is connected to the rotatable metal fitting 57.

  The rotatable metal fitting 57 is connected to the fixed shaft 53 by the rotating portion 58, and has a spherical tip at the rotating portion 58, and the spherical portion is fitted to the tip portion of the fixed shaft 53. In the range below the fixed shaft 53, the fixed shaft 53 is rotatable.

  Further, the rotatable metal fitting 57 has a structure in which the portion connected to the rope 47 can freely rotate with respect to the spherical portion of the rotating portion 58.

  12 (b) and 12 (c), the fixed shaft 53 has been described as a structure fixed to the main body portion. However, like the free rotation shaft 50 in FIG. It is good also as a shaft of the structure which can rotate freely.

  In any of the structures shown in FIGS. 12A to 12C, even if the main body portion of the environmental purification device 25 rotates, the rope 47 is not affected by the rotational force, so the rope 47 is not twisted. Further, even when a force that is obliquely pulled by the rope 47 is applied to the environmental purification device 25, the environmental purification device 25 can float without being affected by the lateral force without breaking the posture.

  FIG. 13 is a view for explaining another mooring method in which the rope 47 does not get tangled in water even when the main body rotates.

  The environment purification apparatus 25 shown in FIG. 13 has a configuration in which a pulley 80 on which a rope 47 is hung is provided at the tip of the rotary shaft 27 instead of the rotatable fastening portion 48 of the environment purification apparatus 25 shown in FIG. .

  The pulley 80 is attached to the front end of a shaft that can freely rotate with respect to the main body portion of the environmental purification device 25 and the rotation shaft 27, like a free rotation shaft 50 shown in FIG. Therefore, even if the main body portion of the environmental purification device 25 rotates with respect to the rope 47, the direction of the pulley 80 does not change, so that the ropes 47 hanging down before and after the pulley do not get entangled.

  Further, a weight 81 is attached to the tip of the rope 47 opposite to the anchor 46 side, and the tip of the rope 47 is pulled down in the vertical direction by the weight of the weight 81.

  Although the position of the water surface rises or falls due to the weather or the like, when the water surface rises, the position of the environmental purification device 25 rises and the tip of the rope 47 to which the weight 81 is attached also rises upward.

  When the water surface descends, the tip of the rope 47 is pulled down by the weight of the weight 81, so the length of the rope 47 between the pulley 80 and the anchor 46 is shortened, and the rope 47 between the pulley 80 and the anchor 46. Is not slackened, so that the rope 47 can be prevented from being entangled.

  FIG. 14 is a diagram illustrating another mooring method in which the rope 47 does not get tangled in water even when the main body rotates.

  In the mooring method shown in FIG. 14, as in the case of FIG. 11, the environmental purification device 25 is fixed by ropes 47 connected to a plurality of anchors 46 fixedly installed at positions away from the water bottom.

  As shown in FIG. 14, a rope isolation ring 59 is connected to each rope 47 at a plurality of predetermined distances from the environment purification device 25. Each rope 47 is fixedly connected to the ring-shaped portion of the rope isolation ring 59 at positions separated from each other.

  The rope isolation rings 59 arranged adjacent to each other in the vertical direction are arranged at intervals that do not intersect with the adjacent ropes 47 even when they are relatively rotated.

  The rope isolation ring 59 is an example of the ring-shaped member of the present invention.

  In FIG. 14, three rope isolation rings 59 are provided as an example, but an appropriate number of rope isolation rings 59 are arranged at appropriate intervals according to the installation position of each anchor 46 and the water depth.

  By adopting such a mooring structure, it is possible to prevent the plurality of ropes 47 from being entangled even when the plurality of anchors 46 are moored by the rope 47.

  FIG. 15 is a view for explaining another mooring method in which the rope 47 does not get entangled in water even when the main body rotates.

  The other end of the rope 47 whose one end is connected to one anchor 46 is connected to one end of the float rod 60 floating in water.

  The float rod 60 is a rod having buoyancy that floats on water such that the longitudinal direction is the vertical direction. For example, a hollow rod having a weight disposed at one end.

  A rotation support portion 61 extending in the horizontal direction is provided on the upper surface of the environmental purification device 25, and can be freely rotated about the longitudinal direction of the float rod 60 by a rotation connection portion 63 at the tip thereof. In addition, it is connected to the float rod 60.

  The float rod 60 is an example of the rod-shaped member of the present invention, and the configuration in which the rotation support portion 61 and the rotation connecting portion 63 are combined corresponds to an example of the connector of the present invention.

  Even when the environmental purification device 25 moves on the surface of the water under the influence of wind or waves, it moves while maintaining a predetermined distance from the float rod 60, so that it does not come into contact with the float rod 60 or the rope 47.

  Further, since the float rod 60 is not affected by the force of the environment purification device 25 rotating, the rope 47 is not twisted.

  In the example shown in FIG. 15, the rotation connecting portion 63 is configured to be rotatable about the longitudinal direction of the float rod 60, but the rotation connecting portion 63 is in the vertical direction, that is, the float rod 60. It is good also as a structure which can move freely also in a longitudinal direction. With such a configuration, even when a wave is generated and the water surface moves up and down, the environmental purification device 25 can float on the water surface stably without being affected by the vertical movement of the float rod 60.

  FIG. 16 is a view for explaining another mooring method in which the rope 47 does not get tangled in water even when the main body rotates.

  The float rod 82 shown in FIG. 16 has a structure that floats on water so that the longitudinal direction is the vertical direction, like the float rod 60 shown in FIG. The float rod 82 has a structure having a buoyancy such that the longitudinal direction is a vertical direction by a float portion 83 attached to the upper portion.

  Similarly to the configuration shown in FIG. 15, the main body of the environmental purification device 25 is floated by the rotation support portion 61 provided on the upper surface of the environmental purification device 25 and the rotational connection portion 63 at the tip thereof. It is connected to the float rod 82 so that it can freely rotate around the longitudinal direction.

  In addition, the structure which put together the rotation support part 61, the rotation connection part 63, and the float stick | rod 82 corresponds to an example of the peripheral accessory member of this invention.

  A pulley 84 on which a rope 47 can be hung is provided at the top end of the float rod 82. The float rod 82 has a cylindrical shape with an open bottom end. As shown in FIG. 16, the rope 47 is folded over a pulley 84 and both ends of the rope 47 are connected to the bottom end portion of the float rod 82. It has a structure that protrudes from the opening.

  One end of the rope 47 is fastened to the anchor 46, and a weight 86 is attached to the other end, and the tip portion of the rope 47 is pulled down in the vertical direction.

  In addition, a partition plate 85 is provided inside the cylindrical shape of the float rod 82 so that the ropes 47 folded back by the pulley 84 are not entangled.

  When the water surface rises, the position of the float rod 82 rises and the tip of the rope 47 to which the weight 86 is attached also rises upward.

  When the water surface descends, the tip of the rope 47 is pulled down by the weight of the weight 86, so that the rope 47 between the pulley 84 and the anchor 46 is shortened, and the gap between the lower opening of the float rod 82 and the anchor 46. Since the rope 47 does not slack, the rope 47 can be prevented from being entangled in the meantime.

  In the example shown in FIG. 16, the rotation connecting portion 63 is configured to be rotatable about the longitudinal direction of the float rod 82. However, as in the case of the configuration shown in FIG. 63 may be configured to freely move in the vertical direction, that is, in the longitudinal direction of the float rod 82.

  In FIG. 16, the rope 47 is passed through the cylindrical float rod 82, but a configuration without the float rod 82 may be used. For example, it is good also as a structure which attaches a pulley directly to the front-end | tip part of the rotation support part 61, without using the float stick | rod 82. FIG. Even if a rope 47 having one end fastened to the anchor 46 and a weight 86 attached to the other end is mounted on the pulley, the same effect as described above can be obtained. However, in this case, it is desirable to attach the pulley so that the direction of the pulley is rotatable with respect to the rotation support shaft 61.

(Embodiment 3)
In FIG. 17, the side view of the environmental purification apparatus of Embodiment 3 of this invention is shown.

  In the environmental purification apparatus according to the third embodiment, a duct 62 that covers at least the lower side of the blades 28 is attached to the main body 26.

  By providing the duct 62, the water from the bottom can be sucked up efficiently, and the water can be efficiently propelled toward the bottom.

  As shown in FIG. 17, when the duct 62 is attached so as to cover the side of the blade 28 as well, the intrusion of water from the side of the blade 28 can be restricted, so that the pumping effect can be maintained even at deeper water depths. Can do. Similarly, water can be raised from deeper water levels.

  Since the environmental purification apparatus of the present invention can propel water toward the bottom of the water, bacteria that decompose and remove harmful substances and sludge from the bottom of the water can also be sent to the bottom of the water.

  FIG. 18 shows a side view of the environmental purification apparatus of the third embodiment configured to efficiently send bacteria to the bottom of the water.

  As shown in FIG. 18, a bacteria inlet 67 for pouring bacteria is provided on the upper surface of the main body 66 of the environmental purification apparatus 65 of the third embodiment.

  Further, a bacteria storage 68 is provided that communicates with the side surface of the duct 62 by the communication portion 70. The bacteria storage 68 is connected to the bottom of the main body 66 of the environmental purification device 65 by a connection pipe 69. Connected to mouth 67.

  The communication part 70 corresponds to an example of the pipe part of the present invention.

  When water containing bacteria is poured from the bacteria inlet 67, the bacteria are poured into the underwater bacteria storage 68 through the connection pipe 69.

  Since the water in the duct 62 flows downward by the rotation of the blades, the bacteria in the bacteria storage 68 are drawn into the duct 62 through the communication portion 70 and move in the duct 62 toward the water bottom.

  In addition, since the temperature near the water surface rises due to heat from sunlight, if the bacteria storage 68 is installed near the water surface, the poured bacteria are easily killed. Therefore, it is desirable that the bacteria storage 68 be installed at a position where the bacteria are not killed due to the temperature rise near the water surface.

  By adopting such a structure, bacteria that decompose and remove harmful substances and sludge from the bottom can be efficiently sent to the bottom.

  In the case of the environmental purification device 65 having the structure as shown in FIG. 18, even when installed in a large dam or large lake in the target range, for example, a bacteria is periodically carried in a bucket by a motor boat or the like, and the bacteria are input. It can be poured from the mouth 67.

  Since the environment purification apparatus of the present invention has the effect of promoting the stirring and convection of water, it can be used in a water storage tank such as a building or a condominium. Water tanks tend to retain water due to their personality, and the water in the water tank is likely to be generated. By installing and operating the environmental purification apparatus of the present invention in a water storage tank, it becomes possible to prevent water from staying, and the effect of suppressing the generation of water scum and the like and suppressing the water quality deterioration of the used water can be expected.

  The environmental purification apparatus according to the present invention can exhibit the effect of preventing water stagnation with low power even in a wide target area, and purifies not only dams and large lakes, but also water tanks of buildings and condominiums with small target areas. It is also useful as a device.
