Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a lifting gutter provided in a waterway crossing overpasses, and when a lower waterway is flooded, it is provided at an intersection with the lower waterway. The gutter is raised so as not to obstruct the flow of water in the lower channel.

(Outline of the Invention) When two waterways intersect three-dimensionally, if the waterway in the lower waterway increases, the waterway in the upper waterway may obstruct the flow of water in the waterway below. The present invention is to provide a device in which the upper waterway does not become an obstacle to the flow of water in the lower waterway when the waterway in the lower waterway of the two waterways crossing over in this way increases. To aim. For this reason, the present invention provides a gutter body that can be raised and lowered at the intersection of the upper water channel with the lower water channel of the two waterways that intersect three-dimensionally, and if the lower water channel increases in water. This is detected by a water level detector, and an automatic device is operated to raise the gutter body by the gravity of the weight so that the gutter body does not obstruct the flow of water in the water channel below.

Embodiments Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a general view of a lifting gutter according to the present invention,
1 and 2 are waterways that cross over. Reference numeral 3 denotes a gutter which is vertically movable at the intersection of the upper water channel 1 and the lower water channel 2. The elevating mechanism will be described with reference to FIGS. 2 and 3 together.

Numerals 4 and 5 are substantially U-shaped base portions made of concrete provided on both sides of the water channel 2, and the water channel 1 is connected to the base portions 4, 5 and the gutter body. The reference numeral 3 is arranged between the base portions 4 and 5 so as to be able to move up and down and hangs over the water channel 2. Reference numerals 6 and 7 denote steel columns provided on both sides of the gutter body 3, and are erected on the base portions 4 and 5. Reference numerals 8 and 9 denote rotating wheels disposed on the columns 6 and 7, and the rotating wheels 8 and 9 are provided with chains 11 and 12 as cord-like bodies, respectively. Instead of the chains 11, 11, other cord-shaped bodies such as wires may be banded. One ends of these chains 11 and 12 are provided with rotary rods 13 and 14 attached to both sides of the gutter body 3, respectively.
Is attached to the tip end of the
It is attached to the weights 15 and 16 arranged inside 7. Reference numeral 17 is a stopper that defines the lowering limit of the weights 15 and 16.

The rotating rods 13 and 14 are rotatably mounted around a pin 24 on a receiving member 23 on support plates 21 and 22 which are fixed by being stretched over both side surfaces of the gutter body 3 (also in FIG. 4). See also). Further, the rear ends of the rotary rods 13 and 14 are provided with the base portions 4 and 5,
It is grounded on the receiving plates 25 and 26 that are fixedly installed by being hung on the inside of the. The length L1 from the pin 24 to the attachment of the chains 11 and 12 is considerably longer than the length L2 from the pin 24 to the ground contact portion with the receiving plates 25 and 26. Therefore, the chains 11 and 12 have the weights 15 and 16 of the weights 15 and 16, respectively. When the levers are pulled upward by gravity, the levers 13 and 14 can be rotated by a relatively small force with the receiving plates 25 and 26 as fulcrums by the principle of leverage. That is, the rotary rods 13 and 14 are boosting portions for raising the gutter body 3 with a small force. As the boosting portions, other than this principle, other principles such as the principle of pulleys may be used. Although FIG. 4 shows the rotary rod 13 side, the rotary rod 14 side has the same structure as the rotary rod 13 side.

Reference numeral 29 is a wire, which is attached to pulleys 27 and 28 coaxially attached to the rotating wheels 8 and 9. The wires 29 and the pulleys 27 and 28 are for keeping the rotation amounts of the rotary wheels 8 and 9 always the same, and for raising and lowering the gutter body 3 in a horizontal state without tilting.

Reference numeral 30 is a known automatic device arranged on the base portion 4, 31 is a float as a water level detector for detecting the water level of the lower water channel 2 connected to the automatic device 30, and 34 is an operation handle. The pulley 35 on the side of the automatic device 30 and the pulley 33 coaxially attached to the pulley 8 are provided with an endless chain 32. Is activated, the locked state is released, and the weights 15 and 16 descend due to their own weight. Since the automatic device 30 is well known, its detailed description is omitted. Next, the operation of the above device will be described.

Normally, the gutter 3 is in the lowered position, and the water in the waterway 1 is indicated by the arrow a.
Flowing in the direction. When the lower water channel 2 increases in water, the float 31 floats and the automatic device 30 operates, the locked state is released, and the weights 15 and 16 descend by their own weight.
At the same time, the tip ends of the rotary rods 13 and 14 are pulled up by the chains 11 and 12, and the rotary rods 13 and 14 rotate about the pins 24 with the receiving plates 25 and 26 as fulcrums. Further weights 15, 1
When the gutter 6 descends, the gutter 3 rises, and when the weights 15 and 16 come in contact with the stoppers 17 and 17, the gutter 3 stops ascending. After that, the gutter 3 is held in the ascended position and the upper water channel 1 is held. The water falls into the water channel 2 below. As described above, according to this device, when the water in the lower water channel 2 increases, the gutter body 3 on the upper water channel 1 side that intersects with the water channel 2 is automatically raised, so that the gutter body 3 moves downward. It does not hinder the flow of water in the waterway 2.

By the way, when the gutter body 3 starts to rise, water is present in the gutter body 3, and therefore the weight of the gutter body 3 is extremely heavy. Therefore, a large pulling force is required to start the ascent of the gutter body 3, but since this device is configured with the rotating rods 13 and 14 utilizing the lever principle as described above, it is a relatively lightweight weight. 15 and 16 can also surely start the rise of the gutter body 3. Further, when the gutter 3 is raised and the rear end portions of the rotary rods 13 and 14 are separated from the receiving plates 25 and 26,
The lever principle does not work, but at that time, since the water in the gutter body 3 has already dropped into the water channel 2 below, the gutter body 3 is light, and therefore the weights 15 and 16 ensure the gutter body 3 to be secured. Can be raised to. When lowering the gutter body 3, the operation handle 34 is operated to operate the endless chain 32.
Just rewind.

(Effects of the Invention) As described above, the lifting gutter according to the present invention is provided with a gutter body at the intersection of the upper water channel 1 and the lower water channel 2 of the two water channels 1 and 2 that cross over each other. 3 are arranged so as to be able to move up and down, and rotating wheels 8 and 9 are disposed above both sides of the gutter body 3, respectively, and a string-like body 11 banded to these rotating wheels 8 and 9,
One end of 12 is attached to the side of the gutter body 3 and the other end is attached to the weights 15 and 16, and the rotary wheel 8 is equipped with the water level detector 31 of the water channel 2 below 30. If the lower waterway 2 is flooded, the gutter 3 that intersects with it will automatically rise, so that the gutter 3 becomes an obstacle to the water flow in the lower waterway 2. Can be prevented.
