The dustproof and waterproof performance of the power conditioner 360 is equivalent to IP58, and it is completely waterproof. The external dimensions of the power conditioner 360 are, for example, a width of 445 cm, a height of 698, and a depth of 198 cm. The weight of the power conditioner 360 can be 30 kg or less.

The power conditioner 360 supplies the supplied electric power to the storage battery 300 and the household distribution board via the power transmission pipe 370. The power conditioner 360 can supply a household power supply that can withstand up to, for example, three-phase 200V always 60A and a maximum load of 80A. Further, at the time of 80A power transmission, it is possible to secure the voltage of 80A + electricity used in the system (including the power motor). Further, the power conditioner 360 is arranged inside the wall surface of the storage room 200 and at a position near the ceiling.

Further, the power conditioner 360 has a fan (DC power supply) that is mounted on a desktop personal computer. The size of the fan is, for example, 15 cm × 15 cm × 3 cm, and the number can be one or two. By having such a fan, the power conditioner 360 can suppress power consumption, can create a quiet environment, and can reduce failures.

Details of the lifting device 100 will be described later.

The storage room 200 forms a frame made of a steel frame, has an iron plate attached to the outside, and has a nonflammable heat insulating material inside. The external dimensions of the storeroom 200 can be, for example, 250 cm in width, 120 cm in depth, and 400 cm in height.

By providing the side member so as to surround the four sides of the mounting table 101, it is possible to prevent the generator 330 or the like mounted on the mounting table 101 from falling.

The side member has, for example, a height of 10 cm and a thickness of 5 cm. Of the side members, each member in the longitudinal direction has two holes, for a total of four holes. Two of these four perforations are perforations 113 and perforations 133. The perforations 113 and 133 are formed in a range of about 10 cm or more and about 60 cm or less from one end of the longitudinal member of the side member so as to oppose each other.

Further, the shapes of the perforations 113 and the perforations 133 facing each other are rounded rectangles formed in a substantially horizontal direction, and the size thereof is, for example, 15 cm to 35 cm in the width direction and about 5 cm in the height direction. The shape of the remaining two of the four locations is circular, and the size thereof is, for example, about 3 cm in diameter. The side surface member may be formed not only so as to be orthogonal to the top surface of the mounting table 101 but also to be orthogonal to the lower surface.

Further, a rectangular locking plate 180 is formed at one of the side members of the mounting table 101 (one of the side members in the longitudinal direction). The locking plate 180 is integrally molded with the side surface member. Further, the locking plate 180 is formed with a perforation having a diameter of about 5 cm.

The shape of the bottom plate 102 is rectangular. The size of the bottom plate 102 is not particularly limited, but is 220 to 245 cm in the longitudinal direction and 100 cm to 115 cm in the lateral direction. The thickness of the bottom plate 102 is not particularly limited. The material of the bottom plate 102 is, for example, iron. The bottom plate 102 is provided parallel to and facing the mounting table 101.

The bottom plate 102 has side members integrally molded on all four sides. Each of the side members in the longitudinal direction has two perforations. The shape of two of them (123, 143) is a rectangle with rounded corners formed in a substantially horizontal direction, and the size thereof is, for example, about 35 cm × 5 cm. The shape of the other two places is circular, and the size thereof is, for example, about 5 cm in diameter.

The pair of legs (two legs) that are combined in an X shape and support the mounting table 101 so as to be able to move up and down are composed of a member 110, a member 120, a member 130, and a member 140. The shapes of the members 110 to 140 are cylindrical.
More specifically, in one leg, the member 110 and the member 120 connect the mounting table 101 and the bottom plate 102 to each other in the vertical direction, and the member 110 and the member 120 intersect in an X shape. Consists of.

The size of the members 110 to 140 is not particularly limited, but the bottom diameter is about 5 cm and the height is about 200 cm. The material of the members 110 to 140 is, for example, iron. Each member of the members 110 to 140 has a total of three perforations at the center of the member and near both ends.

The member 110 and the member 120 are combined in an X shape by screwing a screw 152 into a hole formed in the center of each member. The member 110 is located outside the member 120.

The member 110 is coupled to the horizontal member 153 (described later) through the circular perforation formed in the side surface member of the bottom plate 102 by screwing the screw 111 into the perforation formed near the lower end portion. .. The upper end portion of the member 110 is screwed into the perforation formed near the upper end portion by screwing the screw 112 from the outside with the perforation 113 formed in the side surface member of the mounting table 101 sandwiched therein, thereby forming the side surface member of the mounting table 101. On the other hand, it is connected so that it can slide in a substantially horizontal direction. That is, since the perforation 113 has a rectangular shape with rounded corners formed in a substantially horizontal direction, the upper end portion of the member 110 to which the screw 112 is screwed can slide in the substantially horizontal direction according to the shape of the perforation 113. It becomes.

The member 120 is connected to the horizontal member 154 (described later) through the circular perforation formed in the side member of the mounting table 101 by screwing the screw 121 into the perforation formed near the upper end portion. To. The lower end portion of the member 120 is screwed from the outside with the screw 122 formed in the perforation near the lower end portion sandwiching the perforation 123 formed in the side surface member of the bottom plate 102 with respect to the side surface member of the bottom plate 102. It is connected so that it can slide in a substantially horizontal direction. That is, since the perforation 123 has a rectangular shape with rounded corners formed in a substantially horizontal direction, the lower end portion of the member 120 into which the screw 122 is screwed can slide in the substantially horizontal direction according to the shape of the perforation 123. It becomes.

As shown in FIG. 3, since the perforation 113 has a rectangular shape with rounded corners formed in a substantially horizontal direction, the screw 112 can move in the horizontal direction. Similarly, the screw 122 is movable in the horizontal direction. On the other hand, the screw 111 does not move because the perforation to be screwed is substantially the same as the diameter of the screw 111. Similarly, the screw 121 is immovable. Further, since the member 110 and the member 120 are made of iron, they do not expand and contract. Due to these characteristics, the member 110 and the member 120 combined in an X shape can follow the rotational action of the elevating mechanism and support the mounting table 101 so as to be able to elevate.

The member 130 and the member 140 are combined in an X shape by screwing a screw 151 into a hole formed in the center of each member. The member 130 is located outside the member 140.

The member 130 is formed with a horizontal member 153 (described later) through a circular perforation formed in the side member of the bottom plate 102 by screwing a movable screw 131 into one of the perforations formed near the lower end portion.

The upper end portion of the member 130 is screwed into the perforation formed near the upper end portion by screwing the screw 132 from the outside with the perforation 133 formed in the side surface member of the mounting table 101 sandwiched therein, thereby forming the side surface member of the mounting table 101. On the other hand, it is connected so that it can slide in a substantially horizontal direction. That is, since the perforation 133 has a rectangular shape with rounded corners formed in the substantially horizontal direction, the upper end portion of the member 130 into which the screw 132 is screwed can slide in the substantially horizontal direction according to the shape of the perforation 133. It becomes.

The member 140 is coupled to the horizontal member 154 (described later) through the circular perforation formed in the side member of the mounting table 101 by screwing the screw 141 into the perforation formed near the upper end portion. To. The lower end portion of the member 140 is screwed from the outside with a screw 142 inserted into the perforation formed near the lower end portion with the perforation 143 formed in the side surface member of the bottom plate 102 sandwiched therein, so as to the side surface member of the bottom plate 102. It is connected so that it can slide in a substantially horizontal direction. That is, since the perforation 143 has a rectangular shape with rounded corners formed in the substantially horizontal direction, the lower end portion of the member 140 into which the screw 142 is screwed can slide in the substantially horizontal direction according to the shape of the perforation 143. It becomes.

As shown in FIG. 3, since the perforation 133 has a rectangular shape with rounded corners formed in a substantially horizontal direction, the screw 132 can move in the horizontal direction. Similarly, the screw 142 is movable in the horizontal direction. On the other hand, the movable screw 131 cannot move in the horizontal direction because the perforation to be screwed is substantially the same as the diameter of the movable screw 131 (however, the movable screw 131 can move in the rotation direction by the method described later. ). Similarly, the screw 141 does not move horizontally. Further, since the member 130 and the member 140 are made of iron, they do not expand and contract. Due to these characteristics, the member 130 and the member 140 combined in an X shape can follow the rotational action of the elevating mechanism and support the mounting table 101 so as to be able to elevate.

The horizontal member 150 is a rod-shaped member that connects a portion where the member 110 and the member 120 constituting the leg intersect and a portion where the member 130 and the member 140 intersect, and has screws 151 and screws 152 at both ends. A hole to be screwed is formed. That is, the screw 152 screwed into the hole formed in the center of the member 110 and the member 120 is screwed into the hole formed in one end of the horizontal member 150 and is formed in the center of the member 130 and the member 140. The screw 151 screwed into the perforation is screwed into the hole formed at the other end of the horizontal member 150. As a result, the angle formed by the member 110 and the member 120 and the angle formed by the member 130 and the member 140 are variable with the horizontal member 150 as the pivot axis.

The horizontal member 153 is a rod-shaped member that connects the end of the member 110 constituting the leg and the end of the member 130, and has holes formed at both ends for screwing the screws 111 and the movable screws 131. There is. Further, the holes formed at both ends of the horizontal member 153 are arranged at positions compatible with the circular perforations formed in the side surface members of the bottom plate 102. That is, the screw 111 screwed into the hole formed near the lower end of the member 110 is formed in the hole formed at one end of the horizontal member 153 through the circular hole formed in the side surface member of the bottom plate 102. The movable screw 131 screwed into the perforation formed near the lower end of the member 130 is formed at the other end of the horizontal member 153 via the circular perforation formed in the side member of the bottom plate 102. Screw into the hole. As a result, the member 110 and the member 130 are rotatably connected to the side surface member of the bottom plate 102 with the horizontal member 153 as the pivot shaft.

The horizontal member 154 is a rod-shaped member that connects the end portion of the member 120 constituting the leg portion and the end portion of the member 140, and has holes formed at both ends of the screw 121 and the screw 141. .. Further, the holes formed at both ends of the horizontal member 154 are arranged at positions compatible with the circular perforations formed in the side surface members of the mounting table 101. That is, the screw 121 screwed into the hole formed near the upper end portion of the member 120 is a hole formed at one end of the horizontal member 154 through the circular hole formed in the side surface member of the mounting table 101. The screw 141 screwed into the perforation formed near the upper end portion of the member 140 is inserted into the other end portion of the horizontal member 154 through the circular perforation formed in the side surface member of the mounting table 101. Screw into the formed hole. As a result, the member 120 and the member 140 are rotatably connected to the side surface member of the mounting table 101 with the horizontal member 154 as the pivot shaft.

Due to the presence of the horizontal members 150, 153, and 154, the member 110 and the member 120 are located in a relationship parallel to and facing each other with the member 130 and the member 140. Further, the member 110 and the member 120 are connected to the member 130 and the member 140 by mediating the horizontal members 150, 153, and 154. In this way, the horizontal members 150, 153, and 154 mediate between the member 110 and the member 120 and the member 130 and the member 140, so that the member 110 and the member 120 are integrally interlocked with the member 130 and the member 140. it can.

That is, the lifting device 100 is supported so as to be lifted vertically upward by the four corner pillar members 210.

The material of the corner pillar member 210 can be made of iron, for example. The size of the corner pillar member 210 is, for example, about 10 cm × 10 cm × 130 cm. Since the heights of the four corner pillar members 210 are all the same, the bottom surface of the lifting device 100 supported by the four corner pillar members 210 is horizontal.
<Elevating mechanism>
The elevating mechanism is composed of a rotating member 160 and an adjusting screw 170. The rotating member 160 is a member having a rectangular shape with rounded corners, and has a perforation 161 having a rectangular shape with rounded corners in the longitudinal direction. One end of the rotating member 160 is welded and joined to one side member of the bottom plate 102 by a movable screw 131, and the other end is fastened to the locking plate 180 and the adjusting screw 170 via a perforation 161.

The material of the rotating member 160 is, for example, stainless metal. The size of the perforation 161 is about 5 cm on the short side and about 90 to 140 cm on the long side.

The movable screw 131 has a first communication sensor 135 inside. The first communication sensor 135 can receive the rotation start command 430. When the first communication sensor 135 receives the rotation start command 430, the movable screw 131 rotates counterclockwise. At this time, since the movable screw 131 is integrally welded to the rotating member 160, when the movable screw 131 tries to rotate, a turning force 440 (described later) is generated with respect to the rotating member 160 in the rotation direction. To do.

The adjusting screw 170 constitutes a bolt 171 and a nut 172. The bolt 171 has a second communication sensor 173 inside. The second communication sensor 173 can receive the rotation start command 430. When the second communication sensor 173 receives the rotation start command 430, the bolt 171 rotates in the direction of loosening the screw with the nut 172.

The rotating member 160 raises and lowers the mounting base 101 by rotating the movable screw 131 screwed at one end as a pivot shaft.
<Elevating mechanism>
4 and 5 are schematic views showing a process of raising and lowering the lifting device 100 in the power generation system according to the embodiment of the present invention.

As shown in FIG. 4, first, in S401, the sensor 400 measures the inundation water level h when inundation occurs. Specifically, for example, the sensor 400 transmits the ultrasonic wave 410 toward the water surface 420, which is the measurement target of the water level h, and receives the reflected wave from the water surface 420. Next, the sensor 400 calculates the measured height s by multiplying the product of the time from transmission to reception of the ultrasonic wave 410 and the speed of the ultrasonic wave 410 by 0.5. Next, the sensor 400 calculates the water level h by subtracting the measured height s from the installation height H of the sensor 400. In this way, the sensor 400 measures the water level h.

Next, in S402, the sensor 400 determines whether or not the measured water level 420 is equal to or higher than a predetermined height. The predetermined height can be, for example, 10 cm, but is not particularly limited.

When the measured water level h is equal to or higher than the predetermined height, the sensor 400 transmits a rotation start command 430 to the movable screw 131 and the adjusting screw 170 in S403. If the measured water level h is not equal to or higher than the predetermined height, the sensor 400 ends this step.

Next, as shown in FIG. 4, in S404, the movable screw 131 receives the rotation start command 430 transmitted from the sensor 400 and rotates, so that a turning force 440 is generated in the rotating member 160. .. Specifically, when the first communication sensor 135 included in the movable screw 131 receives the rotation start command 430, the movable screw 131 rotates counterclockwise. At this time, since the movable screw 131 is integrally welded to the rotating member 160, when the movable screw 131 tries to rotate, a turning force 440 is generated with respect to the rotating member 160 in the rotation direction.

Next, in S405, the adjusting screw 170 rotates by receiving the rotation start command 430 transmitted from the sensor 400, so that the tightening is loosened. Specifically, when the second communication sensor 173 of the bolt 171 constituting the adjusting screw 170 receives the rotation start command 430, the bolt 171 rotates in the direction of loosening the screw with the nut 172.

Therefore, in S406, the rotating member 160 rotates when the adjusting screw 170 rotates by the turning force 440 and S405 generated by the movable screw 131 in S404 and the tightening is loosened. That is, the rotating member 160 cannot resist the turning force 440 due to the loosening of the adjusting screw 170 that has been fastened to the locking plate 180 through the perforation 161 and rotates. As the rotating member 160 rotates, the adjusting screw 170 slides in the major axis direction of the drilling 161.

In this way, when the inundation occurs, the inundation water level h is measured, and when the measured water level h is equal to or higher than a predetermined height, the mounting table 101 on which the generator 330 or the like is placed is raised by the elevating device 100 to cause the inundation. When this occurs, it is possible to prevent the generator 330 from collapsing or submerging and the power generation system from stopping the power supply.

FIG. 6 is a schematic view showing how the power generation system according to the embodiment of the present invention stops or starts operating.

As shown in FIG. 6A, the sensor 400 calculates the water level rising speed v, and when the calculated water level rising speed v is larger than the predetermined speed u, sends the first operation stop command 710 to the control device 340. Then, the operation of the power motor 310 is stopped.

As shown in FIG. 6B, the sensor 400 calculates the water level rise speed v, and when the calculated water level rise speed v is 0, sends an operation start command 810 to the control device 340 and power motor. The operation of 310 is started.
<Stop operation>
FIG. 7 is a schematic view showing a step of stopping the operation of the power generation system according to the embodiment of the present invention.

First, in S701, the sensor 400 measures the amount of change Δh in the water level during a predetermined time Δt.

Next, in S702, the sensor 400 calculates the water level rising speed v by dividing the measured amount of change Δh by a predetermined time Δt.

Next, in S703, the sensor 400 determines whether or not the calculated water level rising speed v is larger than the predetermined speed u. When the calculated water level rising speed v is larger than the predetermined speed u, the process proceeds to step S704. When the calculated water level rising speed v is equal to or less than the predetermined speed u, this step is terminated.

Next, in S704, the sensor 400 transmits the first operation stop command 710 to the control device 340.

Next, in S705, the control device 340 receives the first operation stop command 710 and transmits the second operation stop command 720 to the power motor 310.

Next, in S706, the power motor 310 receives the second operation stop command 720 and stops the operation.

In this way, when the inundation situation tends to deteriorate by measuring the water level rise speed v of the inundation water level h at the time of inundation and stopping the power generation when the measured water level rise speed v is equal to or higher than the predetermined speed u. , It is possible to prevent the power generation system from continuously supplying power to the household distribution board and causing a secondary disaster such as an electric leakage or a fire in the house.
<Start of operation>
FIG. 8 is a schematic view showing a process of starting operation of the power generation system according to the embodiment of the present invention.

First, in S801, the sensor 400 measures the amount of change Δh in the water level during a predetermined time Δt.

Next, in S802, the sensor 400 calculates the water level rising speed v by dividing the measured amount of change Δh by a predetermined time Δt.

Next, in S803, the sensor 400 determines whether or not the calculated water level rising speed v is 0. When the calculated water level rising speed v is 0, the process proceeds to step S804. If the calculated water level rise rate v is not 0, this step is terminated.

Next, in S804, the sensor 400 transmits the first operation start command 810 to the control device 340.

Next, in S805, the control device 340 receives the first operation start command 810 and transmits the second operation start command 820 to the power motor 310.

Next, in S806, the power motor 310 receives the second operation start command 820 and starts the operation.

In this way, by measuring the water level rise speed v of the flooded water level h at the time of inundation and starting power generation when the measured water level rise speed v is 0, when the inundation situation is stagnant or converging, The power generation system can resume power supply to the household distribution board.

The control device 340 can also be set so that the power motor 310 does not transmit the second operation start command 820. In this way, by selecting the setting that does not restart the operation of the power motor 310, the power generation system can prevent the occurrence of the secondary disaster in a situation where there is a risk of causing a secondary disaster.
