Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a water splitting device capable of dividing a water body of a hydrosphere such as a reservoir or a lake.

[Prior Art] Conventionally, a reservoir as a hydrosphere provided in an amusement park,
It is often used for applications such as floating pleasure boats and boats, but in the past, they were generally extremely static and lacked in dynamic elements, and were beyond the scope of mere appreciation.

[Problems to be solved by the invention] In order to make up for the lack of dynamic elements in this way, various measures such as installing a fountain have been made, but they are not powerful and leave the area for viewing. is not. Therefore, the conventional hydrosphere has a problem that it is not used as an amusement park or other feature, lacks show-like elements, lacks topicality, and has low attention.

In consideration of the above circumstances, the present invention was made based on an extremely novel idea of dividing the water area of the hydrosphere, which enhances the utilization of the hydrosphere to make it separate from a mere object of appreciation and a very dynamic show. It is an object of the present invention to provide a hydrosphere breaker capable of establishing a system and dramatically improving topicality and attention.

[Means for Solving the Problem] A hydrosphere breaking device according to the present invention is provided with a partition wall so as to be submerged below the water surface of the hydrosphere, and the partition wall forms a specific area in the hydrosphere. The water is configured to be discharged to the drainage system through the opening / closing means, and the partition wall
It comprises a fixed wall and a movable weir that moves up and down with respect to the top of the fixed wall.

[Operation] According to this configuration, by controlling the opening and closing of the opening and closing means, not only the control of the water level lowering and rising in the specific area and the fluctuation speed of the water level, but also the division of the water area in the specific area is performed on a large scale. Can be made.

That is, if the opening / closing means is closed, water is not discharged from the specific area to the drainage system, so the water overflows the partition wall to fill the specific area, and the water level in the specific area and the water level outside the hydrosphere are A static hydrosphere is formed by becoming a peer.

When the opening / closing means is opened, the water in the specific area is discharged into the drainage system, and the water level in the specific area is lowered. Then, even when the water level in the specific area is falling or when the water level reaches the lowest level, the water in the hydrosphere outside the specific area continues to overflow the partition wall, so the overflow water creates a waterfall that falls along the partition wall. At the same time, while the water level is descending, it looks as if the hydrosphere is being torn apart in a specific area and the hydrosphere is being torn apart, and after the water level reaches the lowest level, the hydrosphere is maintained in a torn state.

When the water level in the hydrosphere is constant, lowering the movable weir lowers the upper level of the partition wall (hereinafter referred to as weir height), and raising the movable weir increases the weir height. Therefore, when the water level is the same in the specific area and the hydrosphere outside it, and one static hydrosphere is formed (when the opening / closing means is closed), the movable weir is moved downward. It becomes deeply immersed and becomes hard to see or disappear from the surface of the water. In addition, if the movable weir is moved downward while the waterfall is being produced by the overflow water while the water level in the specific area is being lowered or when the water level has reached the lowest level (when the opening / closing means is open), a large amount of water will fall. A waterfall with a thick film and a dynamic posture is produced, and when the movable weir is moved upward, a waterfall with a small amount of water and a thick fall water film is produced.

Further, when the water level in the hydrosphere fluctuates, it is possible to appropriately control the weir height by moving the movable weir up and down in response to the water level fluctuation.

[Example] In this example, a vast natural reservoir is used as the hydrosphere 1 as shown in FIG. 1, and a specific region S is formed in the hydrosphere 1. The specific region S is a partition wall with a predetermined space W therebetween.
It is made to cross the hydrosphere 1 by partitioning the hydrosphere 1 with 2, 2 and the shield walls 3, 3 between the ends of the bulkheads 2, 2, and the upper end 2A of the bulkhead is more than the upper end 3A of the shield wall. Haze is set low. Then, the water surface WL of the hydrosphere 1 is set at a position higher than the partition wall upper end 2A and lower than the shielding wall upper end 3A, and the partition wall upper end 2A sinks (immersion amount = t) under the water surface WL. . The bottom ends of the partition walls 2, 2 are continuous by the bottom portion 4. This specific region S has a water storage volume corresponding to width W × length L × depth D.

A water passage 5 is provided in the bottom portion 4 of the specific area S. Depending on the size of the water storage volume of the specific region S, the water passage port 5 may be provided singly or in plural at predetermined intervals.

Reference numeral 7 denotes a water storage area, and the water storage volume of the water storage area 7 is larger than the water storage volume of the specific area S, and is set to, for example, twice or more the water storage volume of the specific area S. The water passage 6 in which the opening / closing means V ₁ is interposed connects the water passage 5 and the internal space of the water storage area 7, and the opening / closing means V ₁ , the water passage 6 and the water storage area 7 form a drainage system. . Each water passage 6 has a large passage cross-sectional area corresponding to the opening area of the water passage 5, and is arranged below the height of the water passage 5.

A pump P is installed in the water storage area 7, and a circulating water channel 8 extending from a discharge port of the pump P opens into a hydrosphere (hereinafter referred to as an external area) 1A outside the specific area S.

The opening / closing means V ₁ is composed of a known passage opening / closing means such as an opening / closing valve.

Next, the partition wall 2 is constituted by a fixed wall 21 and a movable weir 22 which is vertically moved (moving direction is indicated by an arrow X) with respect to a top portion 21a of the fixed wall 21. In this partition wall 2, the movable weir 22 may be configured to move up and down above the top portion 21a of the fixed wall 21 or may be configured to move up and down above and below the top portion 21a of the fixed wall 21. Good. Movable weir
As means for moving the 22 up and down, various types such as a manual type, an electric type, or a means utilizing fluid pressure can be adopted. FIG. 4 shows an example in which fluid pressure is used as a power source for the movable weir 22, and a fluid cylinder such as a pneumatic cylinder or hydraulic cylinder is adopted as the drive source 9, and the movable weir 22 is connected to the piston rod 91 thereof. There is. Further, FIG. 5 shows an example in which electric power is used as a power source of the movable weir 22, and a pinion rack mechanism is adopted as a drive source 9 and is linked with an electric motor M. The movable weir 22 is structured so that its vertical movement is guided by a guide mechanism (not shown). As the guide mechanism, a known mechanism such as a mechanism having a groove-shaped member that holds both end portions of the movable weir 22 so as to be vertically movable is adopted.

The operation of the movable weir 22 configured to move up and down above the top portion 21a of the fixed wall 21 will be described. In this case, since the top of the movable weir 22 always corresponds to the partition wall upper end 2A regardless of the position of the movable weir 22 in the vertical direction, the height of the weir and the height of the top of the movable weir 22 always match. .

Since the position of the water surface WL of the hydrosphere 1 is higher than the partition upper end 2A of the specific region S, when the water level of the specific region S is lower than the water level of the outer region 1A, the water overflowing the partition upper end 2A constantly flows in. Therefore, if the opening / closing means V ₁ is closed, the specific area S
Water in the specific area S
Becomes full and its water level becomes the same as that of the outer area 1A, and the whole hydrosphere 1 becomes one static water area. Therefore, it is a static viewing object.

In this way, in the case where the whole hydrosphere 1 is one static water area, if the upper end 2A of the partition wall is set at a position close to the water surface WL, it can be seen from above the water surface WL and the existence of the partition wall 2 There are cases where the viewer understands the mechanism for creating a waterfall, which will be described later, and the effect of the production is hindered. In such a case, the movable weir 22 may be moved downward to deepen the submerged depth of the partition upper end 2A so that the partition 2 cannot be seen from above the water surface WL. For example, it becomes possible to prevent the above situation from occurring.

When water is stored in the water storage area 7, it is possible to return the water to the external area 1A through the circulating water passage 8 by the action of the pump P.

When the opening / closing means V ₁ is opened in the case where the water storage area 7 has a sufficient water storage capacity for receiving the water in the specific area S and the specific area S is full, the specific area S and the water storage area are opened. The water in the specific region S flows into the water storage region 7 through the water passage 6 due to the water drop from the water in the specific region S, and the water level in the specific region S decreases accordingly. In this case, it is possible to speed up or slow down the water level by controlling the opening degree of the opening / closing means V ₁ . While the water level in the specific area S is decreasing or after the water level reaches the lowest level,
The water overflowing from the upper end 2A of the partition wall continuously flows down to the specific area S to create a waterfall, and the partition wall 2 is covered by the falling water film at that time. Therefore, to the viewer, the drop in the water level looks as if the water area of Hydrosphere 1 is being torn by the ebb tide, giving a very dynamic impression. Further, since the overflow water is similarly drained from the water passage 5, if the bottom surface of the specific area S is exposed when the water level reaches the lowest level, a person can walk around the broken portion. It is also possible to use the water-split portion for other events.

When the movable weir 22 is moved upward to bring the upper end 2A of the partition wall closer to the water surface WL during the production of such a waterfall, the height of the weir increases and the amount of water overflowing the partition wall 2 decreases, resulting in a small amount of water and a falling water film. While a thin waterfall is produced, when the movable weir 22 is moved downward to move the partition upper end 2a away from the water surface WL, the weir height becomes low and the partition 2
The amount of water that flows over the river increases, creating a dynamic waterfall with a large amount of water and a thick falling water film. Therefore, for example, when the waterfall is rendered, the movable weir 22 is changed from moment to moment, and accordingly, the form of the waterfall changes sequentially.

After the water level in the specific area S reaches the lowest level, in order to fill the specific area S again, the opening / closing means V ₁ is closed and the water in the external area 1A is caused to flow over the partition wall 2 into the specific area S. Just do it.

In addition, the movable weir 22 is moved up and down when the water level of the hydrosphere 1 changes while forming a still water surface, creating a waterfall, or while the specific area S is being filled with water. If the weir height is adjusted to the water level fluctuation by adjusting the height, it is possible to make the partition invisible and to appropriately control the thickness of the falling water film regardless of the water level fluctuation in the hydrosphere 1.

The above is the description of the case where the movable weir 22 is moved up and down above the top portion 21a of the fixed wall 21, but the movable weir 22 is moved up and down at the upper and lower portions sandwiching the top portion 21a of the fixed wall 21. It can also be configured. In this case, the movable weir 22 is fixed wall
When moving vertically above the top portion 21a of 21 the same action as described above is exerted, and the movable weir 22 is fixed wall 21.
When moving downward from the top 21a of the
It comes to match the height of the top 21a of 1.

In the embodiment described above, a natural reservoir is used as the hydrosphere 1, but it is also possible to use artificial ponds, lakes, rivers, etc. as the hydrosphere in the present invention. It is also possible to form the specific region in various shapes such as a circle.

[Effect of the Invention] As described above, the present invention has been made based on an extremely novel idea that has never existed in the past, and divides a vast hydrosphere into specific areas to create an effect as if the hydrosphere was torn. Since it can be performed on a large scale, it becomes possible to remove the hydrosphere from a mere appreciation object and enhance its utilization, and establish a highly dynamic show system, dramatically increasing the topicality and attention You will be able to improve.

Also, since the partition wall is composed of a fixed wall and a rotating weir that moves up and down with respect to the top of the fixed wall, the movable weir can be moved up and down to raise and lower the weir height relative to the water level of the static water surface of the hydrosphere. Will be able to. And that makes the mechanism for producing a waterfall invisible from the surface of the water,
By changing the appearance of the waterfall when creating the waterfall, it will be possible to give the viewer an unexpected and unexpected feeling, so that the topicality and attention can be further improved dramatically. Become. Further, by moving the movable weir up and down, it is possible to set an appropriate weir height in response to the water level fluctuation in the hydrosphere.
