Abstract

PURPOSE:To avoid interruption with the flow of water in the lower water channel by a trough by a method in which a trough is set in a vertically movable manner at the crossing point between the upper water channel and the lower water channel, and when the amount of water in the lower water channel is increased, it is detected by a water level sensor and the trough is raised under the gravity of a weight. CONSTITUTION:When the amount of water in the lower water channel 2 is increased, a float 31 is floated up, an automatic device 30 is actuated and unlocked, and weights 15 and 16 are lowered under their own weights. Rotary levers 13 and 14 are turned around a pin 24 at receiving plates 25 and 26 as supporting points, weights 15 and 16 are lowered, a trough 3 is raised and held on a given rising position, and water in the upper water channel 1 drops to the lower water channel 2. When the amount of water in the lower water channel is increased, the trough crossed is automatically raised, and therefore, interruption with the lower of water in the lower water channel by the trough can be prevented.

Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to an elevating gutter installed in a waterway that intersects with an overpass. The gutter body is raised so as not to obstruct the flow of water in the waterway below.

(Summary of the Invention) When two waterways intersect three-dimensionally, when the water in the lower waterway increases, the upper waterway may become an obstacle to the flow of water in the lower waterway. The present invention aims to provide a device that prevents the upper waterway from becoming an obstacle to the flow of water in the lower waterway when the water in the lower waterway of the two intersecting waterways increases. purpose. For this reason, the present invention provides a gutter body that is movable up and down at the intersection of the upper waterway and the lower waterway, of two waterways that intersect with each other, so that if the water in the lower waterway rises, This is detected by a water level detector and an automatic device is activated 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 waterway below.

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is an overall view of the elevating gutter according to the present invention, with 1
．． 2 is a three-dimensional waterway. Reference numeral 3 denotes a gutter body which is arranged to be able to rise and fall freely at the intersection of the upper waterway 1 and the lower waterway 2, and its elevating and lowering mechanism will be explained with reference to FIGS. 2 and 3 together.

Reference numeral 4.5 denotes a substantially U-shaped base made of concrete provided on both sides of the waterway 20, and the waterway 1 is connected to this base 4.5, and the gutter body 3 is disposed between the base portions 4.5 so as to be able to rise and fall freely, and a hook is passed over the water channel 2. Reference numerals 6.7 are steel supports provided on both sides of the gutter body 3, and are erected on the base portion 4.5. Reference numeral 8.9 denotes a rotary wheel disposed on these supports 6.7, and each of these rotary wheels 8.9 has a string-shaped chain 11.12 tied thereto. Note that other cord-like bodies such as wires may be used instead of the cheno 11.11.

One end of these chinos 11.12 is attached to the tip of the rotation amount 13.14 attached to both sides of the gutter body 3, and the other end is arranged inside the support column 6.7. It is attached to the installed weights 15 and 16. Reference numeral 17 is a stopper that defines the lowering limit of the weights 15 and 16.

The rotation amounts 13 and 14 are determined by the pins 2 being attached to the receivers 23 on the support plates 21 and 22, which are fixed to the upper surface of both sides of the gutter body 3.
4 (see also Fig. 4). Further, the rear end portion of the rotation amount 13.14 is the base portion 4.
The hook is connected to the ground on receiving plates 25 and 26 which are fixedly installed in the interior of the 5. The length Ll from the pin 24 to the attachment of the chino 11.12 is considerably longer than the length L2 from the pin 24 to the grounding part with the receiving plate 25.26, so that the chino 11.12 is attached to the weight 15.16. When pulled upward by gravity, the rotation amount 13.14 can be rotated with a relatively small force using the receiving plate 25.26 as a fulcrum due to the lever principle. In other words, the amount of rotation 13 and 14 is a force multiplier for raising the gutter body 3 with a small force, and the force multiplier may be one that utilizes the principle of a lever or another principle such as the principle of a pulley. . In addition, Fig. 4 shows the rotation amount 1.
Although the third side is shown in the figure, the rotation amount 14 side has the same structure as the rotation amount 13 side.

A wire 29 is tied to a pulley 27.28 coaxially attached to the rotary wheel 8.9. These wires 29 and pulleys 27, 28 are used to keep the amount of rotation of each rotating wheel 8, 9 the same at all times, and to move the gutter body 3 up and down in a horizontal state without tilting.

30 is a well-known automatic device disposed on the base 4, 31 is a float connected to the automatic device 30 and serves as a water level detector for detecting the water level of the water channel 2 below, and 34 is an operating handle. An endless chain 32 is tuned to a pulley 35 on the automatic device 30 side and a pulley 33 coaxially attached to the pulley 8, and when the lower waterway 2 rises and the float 31 rises, the automatic device 30 is activated, the locked state is released, and the weight mechanism 5.16 is lowered by its own weight. Note that since the automatic device 30 is well known, detailed explanation thereof will be omitted. Next, the operation of the above device will be explained.

Normally, the gutter body 3 is in the lowered position, and the water in the water channel 1 is in the direction of arrow a.
flowing in the direction. When the water in the lower waterway 2 rises, the float 31 floats up, the automatic device 30 is activated, the locked state is released, and the weights 15 and 16 are lowered by their own weight.

At the same time, each rotating amount 13.14 has its tip pulled up by the chino 11.12, and rotates around the pin 24 and each receiving plate 25.26 as a fulcrum.

When the weight 15.16 further descends, the gutter body 3 rises, and when the weight 15.16 lands on the stopper 17.17, the rise of the gutter body 3 is stopped. From then on, the gutter body 3 is maintained at the raised position,
Water in the upper waterway 1 falls into the lower waterway 2. According to this device, when the water in the lower waterway 2 increases,
Since the gutter body 3 on the side of the upper waterway 1 that intersects with this is automatically raised, the gutter body 3 does not become an obstacle to the flow of water in the lower waterway 2.

By the way, when the gutter body 3 starts to rise, since water is present in the gutter body 3, the weight of the gutter body 3 is extremely heavy. Therefore, a large lifting force is required to start the raising of the gutter body 3, but since this device is configured with rotating rods 13 and 14 that utilize the lever principle as described above, the relatively lightweight weight 15 .16 also allows the gutter body 3 to start rising reliably. Also, the gutter body 3 rises and the rotating rod 1
When the rear end of 3.14 separates from the receiving plate 25.26, the lever principle stops working, but at that time the water in the gutter body 3 has already fallen into the water channel 2 below, so the gutter body 3 It is light, so the gutter body 3 can be reliably raised by the weights 15 and 16. When lowering the gutter body 3, the endless chain 32 may be reeled back by operating the operating handle 34.

(Effects of the Invention) As explained above, the elevating gutter according to the present invention has a gutter body at the intersection of the upper waterway 1 and the lower waterway 2 of the two waterways 1.2 that intersect with each other. Rotating wheels 8.9 are respectively arranged above both sides of the gutter body 3, and string-like bodies 11.3 are tied to these rotating wheels 8.9.
12 is attached to the side of the gutter body 3, and the other end is attached to the weight 15, 16, and the rotating wheel 8 is equipped with a water level detector 31 of the lower water channel 2. If the water level in the lower waterway 2 rises, the gutter body 3 that intersects it will automatically rise, so that the gutter body 3 will not become an obstacle to the flow of water in the lower waterway 2. can be prevented.
