Description

  The present invention relates to a liquid pumping device, and more particularly to a device capable of pumping liquid even when a large amount of power such as a commercial power source cannot be used.

  In order to raise the liquid from a low place to a high place, a liquid pump (for example, a spiral pump or a reciprocating pump) using a commercial power source is usually used (for example, Patent Document 1).

  Patent Document 1 states that “in the conventional pump device, the operation condition of the pump device was determined in consideration of the worst installation conditions, and thus the performance of the pump device was not fully utilized” (patent In order to solve the above problem, it was made in view of the problem of “Document 1, summary problem”. “The pump device is provided with a control unit that can estimate the motor shaft output and can be operated with a predetermined shaft output. In all areas of use, the pump output can be increased by detecting the shaft output of the pump device and operating at the maximum shaft output ”(Patent Document 1, Summary Solution) Pumping Device (Patent Document 1) Among them, a pumping device) is disclosed.

Japanese Patent Laid-Open No. 2008-101556 (for example, summary, FIGS. 1 to 3 etc.)

  Certainly, the pumping device disclosed in Patent Document 1 is capable of supplying a large amount of liquid at a high speed in a scene where a large amount of power is supplied such as a commercial power source for driving an electric motor (motor) of the pump device. Although it can be pumped up effectively, it can only be used in a place where such a large power supply is possible, so there is a problem that the place where the liquid can be pumped is greatly restricted (a place where a large power supply is difficult) Cannot be used).

  Therefore, an object of the present invention is to provide a liquid pumping device that can pump up liquid even when large electric power such as a commercial power source cannot be used.

The liquid pumping apparatus of the present invention (hereinafter referred to as “the present apparatus”) is a spiral that forms a spiral flow path around a reference line segment from one end to the other end of a reference line segment that is a predetermined line segment. A pumping device comprising: a flow path forming means; a power generating means for converting sunlight into electric power; and a rotating means for rotating the flow path around a reference line segment by the electric power generated by the power generating means. is there.
This apparatus includes a spiral flow path forming unit, a power generation unit, and a rotation unit.
The spiral flow path forming means forms a spiral (screw-shaped) flow path around the reference line segment from one end to the other end of the reference line segment that is a predetermined line segment.
The power generation means converts sunlight into electric power, and usually uses a solar cell, and is configured to generate power when the solar cell receives sunlight.
The rotating means rotates the flow path formed by the spiral flow path forming means around the reference line segment by the electric power generated by the power generating means.
According to such an apparatus, the reference line segment is at a predetermined angle (for example, for example) with respect to the vertical direction in a state where the lower end (one end side) of the spiral flow path formed by the spiral flow path forming unit is infiltrated into the liquid. If the power generation means generates electric power by sunlight, the rotation means rotates the spiral flow path of the spiral flow path forming means around the reference line segment (the spiral flow path is Rotate in a direction to advance upward), the liquid is lifted upward along the spiral channel (Archimedes pump), and finally discharged from the upper end (the other end side) of the spiral channel Is done. Thus, this apparatus is a liquid pumping apparatus that can pump up liquid with electric power generated from sunlight and can pump up liquid even when large electric power such as a commercial power source cannot be used.

In this apparatus, the spiral flow path forming means has a flow path cylinder portion that is a hollow cylindrical member having openings at one end and the other end of the reference line segment, and from one end side to the other end side of the reference line segment. A spiral blade whose outer edge is spirally attached around the reference line segment to the inner surface of the flow path cylinder portion, and the flow path is formed by the inner surface of the flow path cylinder portion and the spiral blade. , And the rotating means may rotate the flow path cylinder portion and the spiral blade around the reference line segment (hereinafter referred to as “cylinder use main apparatus”).
The spiral flow path forming means constituting this apparatus is not limited as long as it forms a spiral (screw-shaped) flow path around the reference line segment from one end to the other end of the reference line segment. For example, (a) the spiral flow path forming means is spirally wound around the reference line segment from one end to the other end of the reference line segment, and the internal space forms the flow path. (B) the spiral flow path forming means has an opening at one end and the other end of the reference line segment, and an inner peripheral surface along the side surface of the cylinder having the reference line segment as an axis. A hollow cylindrical member having a flow path cylinder portion, and a spiral whose outer edge slides in contact with the inner peripheral surface of the flow path cylinder portion spirally around the reference line segment from one end side to the other end side of the reference line segment The flow path is formed by the inner peripheral surface of the flow path cylinder portion and the spiral blade, and the rotating means has the outer edge of the spiral blade as the flow path. Rotating the spiral blade around the reference line segment so as to slide on the inner peripheral surface of the part, (c) a hollow cylindrical shape in which the spiral flow path forming means has openings at one end and the other end of the reference line segment A flow path cylinder part which is a member, and a spiral blade whose outer edge is helically attached to the inner surface of the flow path cylinder part around the reference line segment from one end side to the other end side of the reference line segment, and The flow path is formed by the inner surface of the flow path cylinder portion and the spiral blade, and the rotating means rotates the flow path cylinder portion and the spiral blade (together) around the reference line segment. The thing etc. can be illustrated. In particular, in the case of this apparatus using the cylinder of (c) above, there is no friction between the inner surface of the flow path cylinder part and the spiral blade, and there is little energy loss (the amount of power generated by the power generation means by sunlight is often small). It is preferable to reduce the energy loss as much as possible and use the energy effectively for pumping.) Further, compared to the above (a), etc., the spiral channel formed by the spiral channel forming means is defined as a reference line segment. The amount of liquid discharged when it is rotated once around is easily increased.

In the case of this device using a cylinder, it may be provided with a central shaft that is rotatably supported around a reference line segment and on which the inner edge of the spiral blade is liquid-tightly attached to the outer surface.
Since the spiral flow path forming means is provided with such a central axis, the outer surface of the central axis and the inner edge of the spiral blade are attached in a liquid-tight manner, so that the space between the outer surface of the central axis and the inner surface of the flow path cylinder part Can be reliably liquid-tightly partitioned, and the flow path formed by the spiral flow path forming means can be reliably formed in a spiral around the reference line segment. The central shaft is rotatably supported around the reference line segment, so that the spiral flow path formed by the spiral flow path forming means is supported easily and reliably around the reference line segment. be able to.

In the case of this apparatus using a cylinder, a liquid collection space that is an internal space communicating with the other end of the flow path cylinder rotating around the reference line segment, and a discharge port that discharges liquid by communicating the liquid collection space and the external space And a liquid collection chamber (hereinafter, referred to as “collection chamber equipped main apparatus”).
As described above, according to the present apparatus, the reference line segment extends in the vertical direction while the lower end of the spiral flow path (one end of the flow path cylinder portion in the case of the main apparatus using a cylinder) is infiltrated into the liquid. If the power generation means is inclined to form a predetermined angle (for example, 45 degrees) with respect to sunlight and the power generation means generates power by sunlight, the rotation means rotates the spiral flow path around the reference line segment (spiral flow path). Is rotated in the direction of traveling upward), the liquid is lifted upward along the spiral flow path, and finally the upper end of the spiral flow path (in the case of a cylinder-use main device, It is discharged from the other end of the channel cylinder. Since the liquid discharged from the other end of the flow path cylinder in the case of this apparatus using a cylinder is more convenient when the liquid is used, it should be provided with a liquid collection chamber for that purpose. Also good. The liquid collection chamber collects the discharged liquid by a liquid collection space that is an internal space communicating with the other end of the flow path cylinder that discharges the liquid, and collects the liquid collected in the liquid collection space as a discharge port (the liquid collection space and the outside Since the liquid is discharged from the space to communicate with the space, the liquid can be easily guided from the discharge port to a predetermined place, and the liquid can be used conveniently.

In the case of this apparatus with a liquid collection chamber, the flow channel cylinder has a cylinder flange formed on the outer surface of the flow channel cylinder so as to protrude outward, and the liquid falling from the outer edge of the cylinder flange is discharged. It may be one that is led to the outlet (hereinafter referred to as “the cylinder portion flanged main apparatus”).
As described above, in the case of the cylinder-use main apparatus, liquid is discharged from the other end of the flow path cylinder, but a part of the discharged liquid falls down along the outer surface of the flow path cylinder. There is. Such a liquid that falls downward along the outer surface of the flow path cylinder portion causes a loss of electric power (energy) generated by the power generation means, and reduces the pumping capacity of the apparatus. In order to reduce or eliminate the liquid falling down from the other end of the channel cylinder part along the outer surface of the channel cylinder part, the channel cylinder part is outward (in a direction away from the reference line segment). If there is a cylindrical flange formed on the outer surface of the flow channel cylinder (the outer surface in the vicinity of the other end of the flow channel cylinder) so as to protrude, the liquid falling down along the outer surface of the flow channel cylinder will be Since the liquid drops from the outer edge of the flange, the liquid falling from the outer edge of the cylinder flange may be guided to the discharge port (for example, the cylinder flange exists in the liquid collection space of the liquid collection chamber. By doing so, it is possible to easily and reliably guide the liquid falling from the outer edge of the cylindrical flange to the discharge port.

In the case of this apparatus having a cylindrical flange, the liquid collecting chamber is formed on the one end side of the flow channel cylindrical portion with respect to the cylindrical flange so that the inner edge protrudes inward from the outer edge of the cylindrical flange. (Hereinafter referred to as “the apparatus with a collecting flange”).
The liquid collection flange is formed on one end of the flow path cylinder portion (the opposite end to the other end of the flow path cylinder portion that discharges the liquid) with respect to the cylinder flange, and the liquid collection flange is located closer to the liquid collection flange than the outer edge of the cylinder flange. The inner edge is formed so as to protrude inward (a direction approaching the reference line segment). For this reason, the liquid falling from the outer edge of the cylinder flange is reliably collected by the liquid collecting flange, so that the liquid falling from the outer edge of the cylinder flange is easily and reliably guided to the discharge port.

In the case of this apparatus having a liquid collection flange, a gap may be formed between the cylinder flange and the liquid collection flange.
The liquid collection flange formed on one end side of the flow path cylinder portion with respect to the cylinder flange is such that the inner edge of the liquid collection flange protrudes inward (in the direction approaching the reference line segment) rather than the outer edge of the cylinder flange. Since it is formed, even if there is a gap between the cylinder flange and the liquid collection flange, the cylinder is tilted so that the reference line segment forms a predetermined angle (for example, 45 degrees) with respect to the vertical direction. The liquid falling from the outer edge of the flange part falls outside the inner edge of the liquid collection flange and is reliably collected in the liquid collection space (that is, the liquid does not enter the gap between the tube part flange and the liquid collection flange). Or, if you do, it will be minimal.) And by the clearance gap existing between a cylinder part flange and a liquid collection flange (a cylinder part flange and a liquid collection chamber are non-contact, and a liquid collection flange and a flow-path cylinder part are non-contact, and a liquid collection chamber and Compared to the case where the cylinder flange and the liquid collecting flange are in contact with each other and sliding, the pumping efficiency is reduced by eliminating friction caused by the sliding and reducing energy loss. (It is preferable to reduce the energy loss as much as possible and use the energy effectively in the pumping liquid because the amount of power generated by the power generation means by sunlight is often small).

In the case of the cylinder use main device, a cover that covers at least a part of the channel cylinder along the reference line segment may be provided.
The hollow cylindrical member, which is a hollow cylindrical member, forms the outer surface of what constitutes the helical flow path forming means and is rotated around the reference line segment by the rotating means, so that it collides with other objects. It can be damaged. In order to prevent or reduce this, a cover may be provided that covers at least a part (of course, all) of the flow path tube along the reference line segment.

FIG. 10 is an enlarged cross-sectional view of a portion surrounded by a dotted line N in FIG. The apparatus 11 will be described with reference to FIGS.
The present apparatus 11 generally includes a solar cell panel 91, a device main body 21, and a power supply cord 99 that connects the solar cell panel 91 and the device main body 21.

  The solar cell panel 91 generates power by generating sunlight when the light receiving surface 93 of the solar cell is irradiated with sunlight. The electric power generated by the solar cell panel 91 is supplied to the apparatus main body 21 (specifically, a motor 75 described later) via the power supply cord 99. Although not shown here, the solar cell panel 91 is supported by a support stand (not shown) in a state where the light receiving surface 93 forms a predetermined angle with respect to the ground (not shown) and faces a predetermined direction.

The apparatus main body 21 roughly includes a casing 31 having a hollow cylindrical shape, a pump unit 51 disposed inside the casing 31, and a drive unit 71 for driving the pump unit 51. .
The pump 51 includes a rotating shaft 53 having a hollow right circular cylinder (radius r1) having a virtual straight line L as an axis, and a right circular cylinder having a straight L attached to both sides of the rotating shaft 53 as axes. A pair of rotating rods 55a, 55b, a hollow cylinder (radius r3, where r3> r1) having a straight line L as an axis, and a cylinder (radius r2, radius r3) having a straight line L as an axis. A spiral blade 59 formed in a spiral shape around the straight line L between the inner peripheral surface of the cylindrical portion 57 along the side surface of>r2> r1) and the outer peripheral surface (radius r1) of the rotary shaft 53. Thus, the spiral blade 59 is attached to the rotation shaft 53 so as not to rotate around the straight line L, and the spiral blade 59 cannot rotate about the straight line L relative to the inner peripheral surface of the cylindrical portion 57. (Ie, spiral blade 59 and tube) 57 is fixed so as not to be rotatable about the straight line L with respect to the rotating shaft 53.). The spiral blade 59 is liquid-tightly attached to the inner peripheral surface of the cylindrical portion 57 and the outer peripheral surface of the rotating shaft 53, and thereby, between the inner peripheral surface of the cylindrical portion 57 and the outer peripheral surface of the rotating shaft 53. A flow path 61 is formed in a spiral around the straight line L (the spiral blade 59 partitions the space between the inner peripheral surface of the cylindrical portion 57 and the outer peripheral surface of the rotary shaft 53 so that the spiral flow A path 61 is formed.).
The pair of rotating rods 55a and 55b are respectively attached to both sides of the rotating shaft 53, and pass through a cylinder cover upper plate 33 and a cylinder cover bottom plate 35, which will be described later, included in the casing 31, and the cylinder cover upper plate. The bearing 31 (bearings 33b and 35b described later) attached to the cylinder 33 and the bottom cover 35 is pivotally supported around the straight line L with respect to the casing 31.

The casing 31 includes a hollow cylindrical cover 37 having openings on both sides along the straight line L, and a cylindrical cover attached so as to close the opening of the cylindrical cover 37 at one end along the straight line L. A bottom plate 35 and a cylindrical cover upper plate 33 attached so as to close the opening of the cylindrical cover 37 at the other end along the straight line L are provided.
The cylindrical portion cover 37 has a hollow (straight) cylindrical cylindrical portion 38 having openings on both sides along the straight line L, and openings on both sides along the straight line L formed so as to be continuous with the cylindrical portion 38. A water receiving portion 39 having a hollow (straight) cylindrical shape (having a slightly larger radius than the cylinder formed by the cylindrical portion 38), and an inner space 38a of the cylindrical portion 38 and an inner space of the water receiving portion 39. 39a communicates with one of the two openings of the cylindrical portion 38 (the other end side). In the water receiving portion 39, a discharge port 39 c that connects the internal space 39 a of the water receiving portion 39 and the external space 101 is formed in a direction perpendicular to the straight line L.
The internal space 38a of the cylindrical portion 38 has a right circular column shape (radius r4, where r4> r3) with the straight line L as an axis, and the internal space 39a of the water receiving portion 39 has a straight shape with the straight line L as an axis. It has a cylindrical shape (radius r5, where r5>r4> r3). For this reason, the cylindrical portion 57 is fitted in the internal space (internal space 38a, internal space 39a) of the cylindrical portion cover 37 with play. Note that both the dimension Y1 in the straight line L direction of the cylindrical part 57 and the dimension Y2 in the straight line L direction of the rotating shaft 53 (Y2> Y1) are both internal spaces (internal space 38a and internal space 39a) of the cylindrical part cover 37. ) In the direction of the straight line L.
The cylinder cover 37 has open openings at both ends along the straight line L (one of the openings is an opening of the cylindrical portion 38 and the other opening is an opening of the water receiving portion 39). The cylindrical cover bottom plate 35 (thin disk shape having a substantially radius r4) is attached to the cylindrical portion 38 with sufficient strength so as to close the opening on one end side along the straight line L, and the straight line L A cylindrical cover upper plate 33 (a thin disk shape having a substantially radius r4) is attached to the water receiving portion 39 with sufficient strength so as to close the opening on the other end side along the cylindrical portion (the cylindrical cover bottom plate 35 and the cylindrical cover). All of the upper plates 33 are attached to the cylinder cover 37 so that the main surface is substantially perpendicular to the straight line L). The cylindrical cover bottom plate 35 and the cylindrical cover upper plate 33 are formed with rib-shaped reinforcing ribs 35j and 33j so as to cross the main surface in order to improve the strength (the reinforcing ribs 35j and 33j). Both are convex in the direction of the external space 101.)
The cylindrical portion cover bottom plate 35 and the portion of the cylindrical portion 38 in the vicinity of the cylindrical portion cover bottom plate 35 communicate with the internal space (internal space 38a, internal space 39a) of the cylindrical portion cover 37 and the external space 101. A water inlet 32 (small circular hole) is formed.

In particular, as shown in FIG. 10, the end on the tube cover upper plate 33 side (discharge port 39 c side) of both ends along the straight line L of the tube portion 57 is directed outward substantially perpendicular to the straight line L. An annular cylindrical flange 57f is formed so as to protrude. Both surfaces of the cylindrical flange 57f substantially form part of a plane perpendicular to the straight line L.
On the other hand, the inner peripheral surface of the cylindrical portion cover 37 (the portion on the cylindrical portion 38 side of the water receiving portion 39) protrudes in an inward direction substantially perpendicular to the straight line L so as to face the cylindrical portion flange 57f. Thus, an annular cover flange 37f is formed. Both surfaces of the cover flange 37f substantially form part of a plane perpendicular to the straight line L. In addition, a thick portion 57q thicker than other portions is provided in the vicinity of the tube portion flange 57f of the tube portion 57, and the tube portion 57 is reinforced by this thick portion 57q to prevent deformation. ing.
The inner edge of the cover flange 37f is substantially circular with a radius r6 centered on the straight line L, and the outer edge of the cylinder flange 57f is approximately circular with a radius r7 (r7> r6) centered on the straight line L.
The rotating rod 55a attached to the rotating shaft 53 is rotatably supported around the straight line L by a bearing 35b attached to the cylindrical portion cover bottom plate 35, and the rotating rod 55b attached to the rotating shaft 53 has a cylindrical shape. A bearing 33 b attached to the upper cover plate 33 is rotatably supported around the straight line L. The bearing 33b is directly attached to the reinforcing rib 33j so as to be supported with sufficient strength (screwing), and the bearing 35b is directly attached to the reinforcing rib 35j so as to be supported with sufficient strength (screwing). .
The tube portion 57 and the tube portion cover 37 are not in contact with each other, and the tube portion 57 can freely rotate around the straight line L with respect to the tube portion cover 37.
As will be described later, the lower end (the cylinder cover bottom plate 35 side) of the spiral flow path 61 of the pump unit 51 infiltrates into the water, and the straight line L forms a predetermined angle (for example, 45 degrees) with respect to the vertical direction. When the apparatus main body 21 is tilted and the pump unit 51 is rotated around the straight line L (rotated in the direction in which the spiral flow path 61 proceeds upward), the inner peripheral surface of the cylindrical unit 57 and the rotation shaft 53 are rotated. Water (not shown) moves through the spiral flow path 61 formed by the spiral blade 59 partitioning the space between the outer peripheral surface of the two (Archimedes pump), and from the upper end of the spiral flow path 61 Water (not shown) is discharged into the external space 101 through the discharge port 39c. At this time, as shown in FIG. 10, the inner edge of the cover flange 37f is inward (straight line L direction) rather than the outer edge of the cylinder flange 57f. ), The water that has reached the upper end of the channel 61 Not shown), without entering into the gap 107 between the tubular flange 57f and the cover flange 37f, it is discharged from the discharge port 39c (in FIG. 10, an arrow M).

  The driving unit 71 for driving the pump unit 51 is mounted on the driving unit fixing plate 79 so that the rotation axis is parallel to the straight line L and the driving unit fixing plate 79 mounted on the cylinder cover upper plate 33. A motor 75, a drive pulley 77 that is non-rotatably attached to the rotation shaft of the motor 75, a driven pulley 73 that is non-rotatably attached around the straight line L to the rotary rod 55b, and a drive pulley 77 and a follower A belt (not shown) that engages with the pulley 73 and a drive unit cover 78 that covers the motor 75 and the pulleys 73 and 77 are provided. Note that the drive pulley 77 and the driven pulley 73 are each formed by a straight line L in an engagement groove (an annular groove formed around the outer peripheral surface of the pulley) with which a belt (not shown) engaged with the drive pulley 77 is engaged. The drive pulley 77 and the driven pulley 73 are both substantially parallel (both substantially parallel to the straight line L). By engaging a belt (not shown) with each other, if the motor 75 rotates the motor rotation shaft, the driven pulley 73 is rotated via the driving pulley 77 and the belt (not shown), and the rotating rod 55b and the rotating shaft are rotated. The pump part 51 including 53 can be rotated around the straight line L.

In the present apparatus 11, the plurality of water inlets 32 formed in the tube cover bottom plate 35 and the tube cover 37 infiltrate into the water (for example, the water flowing in a river or a groove) (spiral flow). The straight line L forms a predetermined angle (for example, 45 degrees) with respect to the vertical direction so that the lower end of the passage 61 (the cylinder cover bottom plate 35 side infiltrates in water) and the discharge port 39c faces downward. If the solar cell panel 91 is installed at an angle and sunlight is received by the light receiving surface 93 of the solar cell panel 91, the electric power generated by the solar cell panel 91 is supplied to the motor 75 via the feeding cord 99, and the motor 75 Rotate.
The rotation of the motor 75 causes the pump unit 51 to rotate around the straight line L as described above. The spiral flow path 61 formed by the spiral blade 59 partitioning the space between the inner peripheral surface of the cylindrical portion 57 and the outer peripheral surface of the rotary shaft 53 causes water to rotate by rotating around the straight line L of the pump portion 51. However, the spiral channel 61 is raised upward (Archimedes pump), and water is discharged from the upper end of the spiral channel 61 to the external space 101 through the discharge port 39c. As a result, the water flowing through the river or the ditch can be pumped by the present apparatus 11 using solar energy and supplied to the fields or the like.
