Abstract

PURPOSE:To facilitate rolling, restoring, sliding of a gate to regulate artificially to make discharge of sludge and dust possible by providing the gate capable of rolling and up/down motion at a non-powered automatic water level regulating device of a balance-weight type. CONSTITUTION:A gate 1 is held vertically through sheaves 7, 11 and a wire rope 6 by a supporting arm 14 and a balance weight 20 connected with the gate 1 for a normal water level F, while for an increased water level G, it is rolled horizontally automatically about an axis of a hinge pin 2 by its load to discharge flowing water. For a water level H, it returns to the original vertical position. By operating an auxiliary switching machine 26 provided on one side of the arm 14, the gate 1 can be rolled or moved up to a middle position B, so sludge, dust, or large waste under the gate 1 can be discharged down.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention provides a non-powered, balance weight type rollover gate with a bearing slide guide with a built-in gate rotation shaft, and an auxiliary opening/closing device on one side of the support arm. and an automatic water level adjustment device for a waterway equipped with a balance weight.

(Prior art) Various types of automatic water level adjustment devices have been devised in the past, but few have been put into practical use. Radial gates, which release water from the bottom of the gate, require large-scale equipment and are proprietary. The area is large, the cost is high, and the debris floating on the water surface upstream of the gate accumulates, making it undesirable from an environmental health standpoint, and improvement measures have been an issue. In addition, the structure required water supply pipes and drainage pipes, which caused clogging due to sludge, making maintenance difficult.

Prior application filed in view of these points (Japanese Patent Application No. 62-2518)
The automatic water level adjustment device for canals (No. 17) has already been put into practical use, and when there is an abnormal rise in water levels due to thunderstorms, torrential rains, etc., the system maintains the planned water level, rolls over (fully opens) in the downstream direction, releases running water, lowers the water level, and protects crops, etc. The current situation is to prevent flooding damage.

However, depending on where the gate is installed, if the gate is located at the most downstream position in the water system, there will be a lot of debris being washed away.1 Occasionally, bulky debris flowing down the bottom of the waterway will clog the bottom of the overturned gate, causing the gate to become clogged. The problem is how to solve the problem of removing the dust in a simple manner.

(Problem to be solved by the invention) Although there are differences depending on the location where the gate is installed and the surrounding environment, a person who intends to provide an automatic water level adjustment device that can immediately respond to abnormal water rises due to thunderstorms or torrential rains that occur day or night. However, 2 floating objects that flow normally overflow the gate and are discharged. Also, when you want to artificially lower the normal water level, you can keep the gate tilted downstream by adjusting the height of the hanger stopper on the auxiliary opening/closing machine, which reduces the function of the automatic opening/closing gate. Therefore, dust removal measures are required. An attempt was made to solve this problem by installing a roll-up screen upstream of the gate, but the amount of debris flowing day and night was extremely large, and it accumulated on the screen, raising the water level upstream. Problems such as who cleans up the garbage and where to dispose of the garbage have arisen.

In general, in small and medium-sized rivers where dust removers are not installed, the current situation is that the dust floating and accumulating upstream of the gate is released downstream by raising the gate. Improved.

This is an attempt to solve the above-mentioned problem by adding a function that can deal with it.

(Means for solving the problem) A support arm having a fulcrum, one of the arms is equipped with an auxiliary opening/closing machine and a balance weight, and the other gate side is equipped with a slidable bearing operated via a wire rope mechanism. A gate is provided within the slide guide (the rotation axis of the gate is usually set at one-half or less of the gate height).

) In response to abnormal water rises, the gate can easily overturn, allowing the normal water level to be lowered. In addition, when the gate is clogged with bulky garbage or during the winter when the gate is not in use, the gate is not only turned sideways, but also moved up and down vertically so that the gate can be slid to any desired height using an auxiliary opening/closing device. That is.

To further explain the structure of this device, slide guides 5.5 installed on both walls of the waterway have slidable bearings 3, 3 inside them, and a hinge pin 2.2, which becomes the shaft of the gate, is attached from the inside of the gate 1 to the mounting platen. ) 37. Bearing 3 through 37

An auxiliary switch 26 and a slidable balance weight 20 are arranged at one end of a support arm 14.14 installed on a pedestal 15.

On the opposite gate side are shankle simple wire clips (not shown) and sheave 7.7 and sheave 11.
, 11, the gate 1 and the support arm 14.14 are connected by a wire rope 6.6.

A balance weight 20 is attached to the end of the support arm 14.14 via a slidable holding metal fitting 19 so as to generate a moment corresponding to the force for vertically returning the gate 1 from an overturned state when no load is applied. Normally, when the water level is F, the water overflows and is flowed downstream. When the water increases and the water level reaches position G, the gate load increases and gate 1 rolls downstream, and stops at stop 3 at position C.
6.36.

When the period of high water is over and the water level decreases to the H position, the load on the gate 1 is also reduced, and the gate 1 returns to the vertical position due to the action of the balance weight 20 and is held by the stoppers 35 and 35.

(Operation of the invention) In a rollover gate, the gate l is held vertically and then rolls over (opens) in the downstream direction, but the maximum load is required when it starts rolling over, and the load gradually decreases as it becomes horizontal. .

Therefore, the hydraulic load gradually decreases as the gate 1 begins to roll over from a vertical position and its angle increases. Also, it is natural that the more the fulcrum of the gate 1, that is, the setting position of the hinge pin 2.2 of the rotation axis, is at a position less than half of the gate height, the less the load required for the gate to roll over, which will promote the rollover. I will do it.

■ is a waterway and the arrow indicates the direction of the flowing water. The water level F indicates the planned water level during normal times, and the water level F is connected to the support arm 14.14 via the sheave 7.7 and 11.11 with a wire rope 6°6, and the stopper 35.3
5 and is in the vertical state of A-A', and the flowing water overflows the gate 1 and flows downstream. The water level is G
When it reaches c - c', gate 1 rolls over as described above.
When the state (-dotted chain line) is reached, that is, the water level is G, the load is greater on the gate side than on the balance weight side, and the gate 1 rolls over and is held by the stoppers 36 and 36. When the high water period is over and the water level decreases to the H position, the load on the gate side decreases, so the gate 1 returns to the vertical position and is held by the stoppers 35 and 35.

Even when the auxiliary opening/closing machine 26 shown in Fig. 5 is installed, the hanger 2
The structure allows the support arm 14 to move up and down within the gate 9, and the operation of the gate 1 is as described above.

Another feature of this machine is that the amount of water supplied to the fields varies depending on the season, and when you want to artificially lower the water level or treat sediment such as sludge that has settled on the riverbed, you can use the auxiliary switch 2.
6, operate the rotation handle 28 to release the hanger stopper 31.
By raising the position of the gate, the gate is held in the state of 1・B', and running water is also discharged from the bottom of the gate, lowering the water level and helping to wash away deposits such as sludge. Also, when you want to dispose of floating dust. Then gate 1 is further c − c
By approaching the condition ', floating objects upstream of the gate can be discharged.

Furthermore, when the lower part of the gate is clogged with bulky garbage or during the winter when the gate is not in use, the auxiliary opening/closing device 26 is operated to lower the hanger 29 to raise the gate 1 (
The gate 1 can be slid in the vertical direction to discharge bulky waste, and can also hold the gate 1 at the D-D' position.

(Effects of the invention) Bearing guides for the gate hinge pin are arranged on both walls of the waterway, the gate 1 and the support arms 14 and 14 are connected by a wire rope mechanism, and the position of the gate hinge pin is set at less than one-half of the gate height. By installing a slideable bearing, the gate can easily roll over, return, slide, etc., and the slider balance weight and auxiliary opening/closing device can be adjusted to tilt the gate up to about 40 degrees downstream from the vertical position. Since the water level can be maintained in this state, the water level can be adjusted manually, and precipitated sludge and dust can be constantly discharged from the bottom of the gate.

Furthermore, when floating objects accumulate on the flowing water surface, the floating objects can be released all at once by operating the auxiliary opening/closing machine to tilt the gate in the downstream direction and lowering the upper part of the gate below the water surface.

Furthermore, when the gate is held slightly tilted downstream at normal water levels, water is discharged from both the lower side of the gate and the overflow, which has the effect of simultaneously flushing away sludge and floating matter.

Furthermore, if the bulky waste gets stuck at the bottom of the gate, you can operate the auxiliary opening/closing machine to slide the gate upwards.
Bulky waste will be discharged immediately.

The gate can be held in any position during the winter when it is not in use, making it suitable for its original purpose.

Not only is it structurally and functionally compatible with all water level conditions, but it also eliminates the labor required to remove dust and has the immediate effect of preventing the accumulation of floating matter on the river water surface.
