Abstract

PURPOSE:To make easy installation of a lift device practicable by installing a downstream-side lock to the side of the lower part of a lift tower adjacent to a low water area and an upstream-side lock to the side of the upper part of the lift tower adjacent to a high water area, and by providing passages with which the lift tower communicate respectively with both the high and the low water areas. CONSTITUTION:When moving boats F from a high water area 3 to a low water area 1, the water level in a lift tower 6 is made to be the same as the water level of the surface WL1 of the high water area 3 by opening a valve 11 on the upstream side. Then the boats F are allowed to come into the lift tower 6 with a lock 8 on the upstream side opened. Then, by closing the lock 8 and the valve 11 on the upstream side and by opening the valve 12 installed in the middle of a passage 10 connecting the lift tower 6 and the low water area 1, the water level in the lift tower 6 gradually lowers and becomes the same as the water level WL2 in the low water area 1. Then the boats F are moved to a plane water area 1a on the low water area 1 side by opening a lock 7 on the downstream side.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to equipment for lifting and lowering watercraft, and more particularly to equipment for moving a watercraft between two bodies of water at different water levels by adjusting the water level.

(Background of the Invention) The first necessary condition for constructing resort facilities, including port facilities such as mooring for small boats such as yacht harbors facing the ocean, and land-based port facilities, is first of all to have a good port. It is.

In other words, this type of facility C must be located in flat water surrounded by a suitable bay.However, this divine port facility is already occupied by small fishing boats, and other than some special areas, new There is less room than C for providing mooring and berthing facilities for small leisure boats.

Therefore, conventionally, after entering a port, the ship was placed on a trolley and brought back to land using a winch, but even in this case, the land part must be sloped from the sea level. However, the reality is that the height difference is limited to within a few meters, and the installation site must be flat, making it impossible to install a large number of them on land.

In addition, when installed on bogie-L, the hull is supported at two or several points, so depending on how it is supported, unreasonable distortion may be applied to the hull, so it takes time to adjust the support position. It also has drawbacks such as requiring the labor of many people.

This invention solves the above problems,
Its purpose is, for example, to create a slope-like plateau in the sea at a scenic spot.
Establish a large-scale detention facility for this type of boat using a lake or artificial lake located in The purpose of this project is to provide equipment for raising and lowering boats that allows for safe and quick loading and unloading.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a lifting tower installed between two bodies of water with different water levels and accommodating a boat in a floating manner, and the lifting tower. A lower side lock gate and an L section lock that are arranged at the lower and upper parts of the water body and respectively open and close the faces facing each water area to allow boats to pass, and the lower end of the high water area 1jμj and the elevator tower. 4 channels communicating with the vicinity or the bottom, and the low water positioning and the vicinity or bottom of the lower end 11 of the elevator tower, and valves that open and close each channel in conjunction with the opening and closing operations of each of the locks. It is prepared.

(Function) To transfer a boat located in a high water area to a low water area, open the upper lock gate with the water level inside the elevator tower at the same level as the high water area 1jμj, and the boat can be moved to the lower water area. Can be installed internally.

After that, close the upper side lock, lift tower and low water area
If you open the valve of the flow path connecting the tower, the water level inside the elevator will gradually decrease, eventually reaching the low water level of 11! II water surface and 2nd water surface.

If you open the lower side lock in this state, *ni! can move to the lower water side through this lock.

Next is low water! If 1ull water surface, to move the boat located at L to the high water side, move the boat inside the elevator tower 0') with the lower shouting lock open, contrary to the above,
Next, when the lock gate and the valve are closed and the valve of the flow path connecting the high water area and the lifting tower is opened, the water level inside the climbing tower 15 rises by -L and finally reaches the same water level as the high water area. If the upper lock is opened at this stage, the boats housed inside the elevator tower can be moved to high water.

(Remuneration for Implementation) Hereinafter, one embodiment of the present invention will be described in detail using the drawings.

Figures 1 to 4 [2] show the lifting equipment for a watercraft according to the present invention.

In the figure, t ii a low-lying body of water such as the sea, 2
is μ (a steeply sloping white area formed on the seashore at the water line 1, 3 is a high water area consisting of a natural or artificial lake, etc. formed on the top surface of the steeply sloping white area 2, and the formation position of this tall tree Ji!li 3 is There are moorings, berths, large-scale accommodation facilities with abundant equipment and ancillary facilities, and resort facilities in the surrounding area.

In addition, a breakwater 4 is arranged in the area facing the steep plateau 2 of the low water area I, and the breakwater 4 and the steep plateau 211I!
The water area connecting the points 1 and 1 is defined as the flat water area 1a.

Further, in the waterfront area of the steeply inclined plateau 2, a boat lifting facility 5 according to the present invention is provided.

This # descending facility 5 is located at the lower part ((μm) of the low water area 11i1
Facing 11, the upper side is Takagi i! ! The upper side built vertically in the plane Ii3 [1 hollow lifting tower 6 and the F part of the lifting tower 6 ft! On the 11th side there is a lower opening 141 bolt 7 which is arranged so as to be openable and closable in contact with the water body 1, and on the side of the L section of the elevator tower 6 there is a front 1: fS which is arranged so that it can be opened and closed in contact with the high water body 3; A channel 9 that communicates between the h section switching lock 8, the high water area 3 and the vicinity of the lower end of the elevator tower 6 or the bottom '+rb, and the lower end of the elevator tower 6 (approximately .1" or the bottom and the low water area 1 A control stage (consisting of liii L4, etc.) that controls the opening and closing of the upper and lower fifl + valves 11.12 that open and close the flow passages 9 and 10, and each lock 78 and valve 11.12. ing.

In part 1-, the lifting tower 6C18i is set to have a length and a length sufficient to accommodate several boats F, and also has a height of 1.
A pressure-resistant structure 3-1 is provided that can sufficiently withstand water pressure corresponding to the head difference between the water area 3 and the low water area 1.

Furthermore, not only the E section opening/closing lock 8 but also the lower part (country lock 7) are designed to be sufficiently watertight against water pressure.

Next, a case will be described in which the boat F is moved from the high water area 3 to the low water area 1 and vice versa using the lifting facility 5 having the above configuration.

First, a case will be described in which the boat F is moved from Takagi jiii13 to the low water area 1 side.

In this case, as shown in FIG. 1, the upper valve 11 is opened in advance, and the water level inside the lifting tower 6 is at the same water level as the water level WLI of the high water area 3. If the upper lock gate 8 is opened in this state, the boat F can be accessed inside the elevator tower 6.

Thereafter, as shown in FIG. 2, the upper lock 8 and the valve 11 are closed, and the flow path 10 connecting the elevator tower 6 and the low water area 10 is closed.
When the valve 12 is opened by 1 m, the water level inside the elevator tower 6 gradually decreases until it reaches a low water level i fi'! 1 Water level WL
The water level will be the same as 2.

In this state, as shown in Figure 3, if you open the lower lock 7, the boat will be ready! F passes through this lock 7 and enters low water J! You can move to the flat water area 1a with 11 waves, and from here you can enjoy sailing by going over the breakwater 4.

Next, the boat F located on the low water area L water gauge surface is moved to the high water area 3 I.
In order to move the oil to the lower part III, as shown in Fig. 3, the oil and fat F is moved inside the elevator tower 6 in the opposite manner to the above with the lower side lock 7 being 1 m apart, and then the lower shouting lock 7 and the above-mentioned Close the valve 12 and open the valve 11 of the flow path 9 connecting the high water area 3 and the elevator Ji 6.Ill'! The water level of the next descending tower 6 rises by +qI'1 as shown in Figure 4, and finally becomes the same water level as the water level WL of the high water area 3. If the side lock 8 is opened at this stage lag, , n 118 r', which is accommodated in a floating state inside the elevator tower 6, can be moved to the water surface of the high water area 3, and this water area 3
You can use accommodation facilities such as moorings, berths, and camps around the area.

The series of water level raising and lowering operations described above are automatically or semi-automatically performed by lock opening/closing control and valve opening/closing control from the control unit 111.

Since the high water area 3 is naturally a low water area, it is possible to preserve the riverboat F while ensuring its safety.

In addition, in the embodiment, the elevating tower 6 was provided at only one place so that the boat could be raised and lowered directly between the low water area and the high water area on the land side, or the height difference between the high water area and the low water area was large or the boat was placed far away. In such a case, a plurality of elevator towers may be provided adjacent to each other in a stairway manner, and the boat may be moved sequentially into each elevator tower while controlling the water level of each elevator tower to the same water level.

Also, in real A & Irol+, high water area full! The water of I is injected into the inside of the elevator tower and released towards the low water area side, but the amount is extremely small compared to the total water volume of the high water area fltll, so it does not affect the water level and has no effect.

However, in order to save the amount of water discharged, it is also possible to adopt a configuration in which water is injected and discharged into the elevator tower using a pump or the like as an auxiliary means.

In addition, as shown in FIG. 5, a pair of lifting towers 20 that alternately raise and lower the water level are provided, the bottoms of which are connected through a communicating pipe 21, and a four-way tower is installed in the middle of the communicating pipes 21. A configuration in which water stored in both valve towers 20 is delivered and received depending on the driving direction of the pump 22 is also possible.
