Description

[Detailed explanation of the idea] The present invention relates to a U-shaped lock type ship lifter.

For example, when a dam is installed on a waterway, ships cannot pass through it using normal methods.

Therefore, it is being considered to install a lock-type lifting equipment in the above dam, and lower the ship from the upper waterway to the lower waterway by releasing water, and raise it from the lower waterway to the upper waterway by pumping water, but this type of lifting equipment This results in a large amount of dam water being discharged downstream, which poses a major problem in terms of the dam's original functions (power generation, flood control, etc.).

Therefore, the present invention provides a U-shaped lock type ship lifter that solves these problems.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

1 is a dam installed between an upper waterway 2 and a lower waterway 3, and a partition wall 1c is provided between both side walls 1a and 1b of this dam 1. From the downstream end of the upper waterway 2 to the upstream end of the lower waterway 3, both waterways 2 and 3 are partitioned into two branch waterways 4a and 4b.

Reference numeral 5 denotes a partition wall provided on the side of the lower waterway 3 in each branch waterway 4a, 4b, and between each partition wall 5 and the stepped portion 6 between both waterways 2.3, there is a cubicle 7a for storing a ship, 7b is formed,
The lower portions of the double lock chambers 7a and 7b communicate with each other via a communication passage 7c.

A U-shaped lock chamber 7 is formed by the communication passage 7C and the double lock chambers 7a and 7b.

Reference numeral 8 denotes an operation chamber formed in the lower part of the partition wall IC, and the two-way lock chambers 7a, ? A pump 9 is provided to send the ice in the compartments 7a and 7b into the other small quiet rooms 7a and 7b.

10 is an opening formed in the lower part of each partition 5, 11 is a first gate provided in the opening 10, and 12 is each partition 5.
This is a lifting device for the first gate disposed at the upper end of the gate.

13 is each branch waterway 4a. 14 is a second gate provided at the end of the upper waterway 2 in each branch waterway 4a, 4b, and 15 is a third gate provided at an appropriate distance upstream from each second gate 13 in each branch waterway 4a, 4b. A fourth gate 16.17 is provided at an appropriate distance downstream from each first gate 11 in each branch waterway 4a, 4b, and 16.17 is a second and third gate 1.
3.14 questions and 1st and 4th games) A water level adjustment device that adjusts the water level between 11 and 15, and includes a communication passage 18, a valve 19, and a water pressure pump 20.

In the above embodiment, the gates 13 and 14 in FIGS.
, 15 are of the double-door type, but the present invention is not limited to this, and it goes without saying that, for example, the first gate 11 may be of the same type.

The operation of the above configuration will be explained.

For example, when one branch waterway 4a is used for lowering the ship 21 and the other branch waterway 4b is used for raising the ship 21, first operate the pump 9 to raise the water level in one booth 7a to the maximum water level. Along with this, the water level in the other booth room 7b is set to the minimum water level.

Next, in one branch waterway 4a, after adjusting the water level of the second and third gates 13.14 to match the water position of the upper waterway 2 using the water level adjustment device 16, the third gate 14 is opened and the vessel 21 is opened. It is inserted between the second and third gates 13 and 14.

Next, after closing the third gate 14, the water level adjustment device 16
Accordingly, the water position between the second and third gates 13 and 14 is made to match the maximum water level A.

Next, the second gate 13 is opened, the vessel 21 is put into one of the small quiet rooms 7a, and the second gate 13 is closed.

At the same time, in the other branch waterway 4b, the water level between the first and fourth gates 11.15 is made to match the water level of the lower waterway 3 by the water level adjustment device 17, and then the fourth gate 15 is opened. The ship 21 is placed at the first and fourth gates 11°1
Put it in between 5.

Next, after closing the fourth gate 15, the water level adjustment device 17
Accordingly, the water level H between the 11th and 4th gates 11 and 15 is made to match the bottom water position.

Next, the first gate 11 is opened, the vessel 21 is put into the other small quiet room 7b, and the first gate 11 is closed.

Next, the pump 9 is activated to send the water in one of the small booths 7a into the other booth 7b through the communication path 7c, and the third
As shown in the figure, the vessel 21 in one small quiet room 7a is lowered, and the vessel 21 in the other small quiet room 7b is raised.

If the water level in one of the small booths 7a reaches the lowest water level (in other words, if the water level in the other booth 7b reaches the maximum water level A), then in one of the branch waterways 4a, After adjusting the water level between the first and fourth gates 11 and 15 to match the bottom water position, the first gate 11 is opened and the vessel 21 is moved between the first and fourth gates 11 and 15. Then, after closing the first gate 11, the water level between the first and fourth gates 11. All you have to do is sail towards it.

In the other branch waterway 4b, after the water position between the second and third gates 13 and 14 is made to match the maximum water level A, the second gate 13 is opened and the vessel 21 is moved to the second and third gates. 13 and 14, then close the second gate 13, match the water position between the second and third gates 13 and 14 with the water position in the upper waterway 2, and open the third gate 14. The vessel 21 may be sailed upstream.

As described above, according to the U-shaped lock type ship lifter of the present invention, a partition wall is provided to partition both the upper and lower waterways into two branch waterways, and a partition wall is provided on the lower waterway side of each branch waterway, so that each A cubicle for storing ships is formed between the bulkhead and the step between the upper and lower rain channels, and the lower parts of the double locks are communicated with each other to form a U-shaped lock. Since the water in each lock chamber is equipped with a pump that sends water into each other's small compartments, the water in both locks can be shared with each other, allowing ships to be lowered from the upper canal to the lower canal and raised from the lower canal to the upper canal. Moreover, at this time, the water stored in the dam will not be released unnecessarily.

Therefore, the original functions of the dam (power generation, flood control, etc.) will not be impaired.

Another advantage is that Mikasa's ships can be raised and lowered at the same time.
