Abstract

PURPOSE:To automatically control the amount of divergent water by a method in which a siphon having openings on both upstream and downstream sides is provided to the sluice door, while the door is vertically moved by a negative pressure generated in the siphon, and the negative pressure is controlled by the water level of the water stream to be controlled. CONSTITUTION:When winch 14 is loosened, a door 3 fully closed is opened until the opening of a water level regulating tube 23 is submerged into water. Water stream is also discharged from an outlet 6 into the downstream side chamber 29 of a siphone 12 provided to the door 3, and the air of the siphone 12 is mixed in the water and discharged to the downstream side. For this reason, the inside of the siphone 12 becomes of a negative pressure, and the water level in the siphon chamber is raised by the negative pressure and further raised by the discharge of water even from the outlet 6 at higher level. Since the top plate 10 is pulled downwards by the negative pressure, the door 3 is slightly closed, the level of divergent water is lowered, and the water level regulating tube 23 is exposed to the air. When a little amount of air is further supplied and the negative pressure is lowered, the movement of the door 3 is stopped, thereby the level of the divergent water 22 is adjusted at the height of the tube 23.

Alternatively, nullus gates or roller gates have been used to stop water diversion, but the water level in the main canal remains
It constantly changes due to the complex effects of numerous factors, such as the water level of the source river, the amount of inflow from other small rivers and waterways, and changes in the water diversion volume of other water diversions. The degree of opening must be adjusted. 'Furthermore, if there was precipitation, the flow rate would increase and it would be necessary to perform operations to shut off the gates, and these operations were extremely difficult, especially in the area. Not only is the adjustment of the gate complicated, the amount of water diverted is inaccurate, and there is also a great risk that the diversion channel will be flooded. This invention deals with the water level of the diversion channel due to changes in the upstream of the water gate J,
In addition, it automatically opens and closes immediately in response to changes in the amount of water diverted, and maintains the amount of water that has not been specified appropriately, and also automatically stops water intake at 71:00, ensuring the safety and security of the diversion channel. It is an attempt to secure and provide a floodgate. First, the mechanism will be explained.

The bar provided with the protrusion 15 is ``secondary +11. ll Ic
There is a water level detection tube 17 that detects l (f human hole 16 and 1), among which the water level detection tube 18 with iC@' and ij folded front opening completely closes its body and shuts off the water diversion. Adjust the water level by adjusting the middle height of the sawtooth to the desired water level and install the Noah 7, and then turn the water through the air pipe 19 and adjust the water level ('V!
1 of the mantle tube 22 located inside i21: n'i I' is the same. The water level regulating pipe 23 provided in the water level regulating tank 21 has a structure that allows its height to be adjusted as desired, and is configured to have a water level of -1. Furthermore, the water level IJ and the one-section pipe 23 communicate with the inside of the siphon 12 through a ventilation pipe 25. j [q trachea 25 is jiit
The movement of the door body near the body is l'1. It is called ft, which does not cause any harm, and there is 1 piece in 1;, 'l l/ko'! l Shimushi C i: (Introduction ability is also equipped with a constriction valve 26 that can be used for ij! 1 -
I'm here. Next, the mud 1 work and each (hat toma function ((・rii°c r
)52. I will clarify. First, the middle of the water level control pipe 23 is set to a predetermined water level. When using the door for the first time, when water is not diverted for a period of time, or when the main waterway water flow is stopped, the door body is fully closed by the winch 14 for safety reasons. In such a case, if the wing 14 is gradually loosened after a sufficient amount of water has passed through the main canal, the door body will open due to the weight C of the counterweight 13, so the water level adjustment pipe 23
Open until the opening is submerged in water, then leave it open! put. At this time, the door body is not fully opened, so there is a water level difference between the upstream and downstream sides of the door body, and from the water outlet 6 to the downstream side room 29F1 of 2.
As water veins are discharged, the air inside the siphon 12 is mixed into the water due to its air-entraining action. Since the water channel is sufficiently small, the outlet of the siphon 12 will not be submerged too deeply, and the mixed air will be easily discharged together with the water. On the other hand, the opening of the water level control pipe is submerged in water and no air is supplied, resulting in negative pressure inside the siphon room. When the pressure becomes negative, the water level in the siphon chamber rises, water is discharged from the water outlet located at a higher position, and the siphon action is reduced by 1 p, causing the negative pressure to increase further. This negative pressure is applied to the top plate at the door body 5.
As the door is pulled in the closing direction, the door body slightly closes, the water volume drops slightly, and a part of the serrated part of the water level control pipe 23 is exposed in the air, supplying a small amount of air into the Seifmen 120 room. When the negative pressure decreases, the door body 3 stops. Therefore, if the winch 14 is further loosened, when the water level in the diversion channel decreases, the negative pressure will decrease and the door will open automatically, while when the water level rises, the negative pressure will increase and the door will open automatically. It closes and maintains a predetermined water level.After that, when the height of the water level adjustment pipe 23 is slowly changed, the gate body opens and closes according to the same principle, and the water level follows. When the flow rate cannot be secured, the water level control pipe 23 opens into the air, and in this case, by loosening the strip winch 14, the door body jumps up into the air, so it does not impede water flow in any way. Except for such special cases, the winch 14 should not be loosened to prevent it from opening into the air even if the upstream and downstream sides of the siphon 12 are accidentally opened. In the event of heavy rain, it is best to preserve water diversion channel 2 and stop water intake in order to prevent floods in the downstream area.
As is common knowledge, if there is heavy rain during automatic operation, the opening of the water level detection tube 18 will be submerged in water, and no air will be supplied at all, so the door will automatically close fully and wait for 7 minutes. The water supply is stopped, and when the flood has passed, the water diversion begins again on its own. During this water diversion suspension period, the lower end of the Zyfon is submerged in water because the waterway bottom protrusion 15 is provided, and negative pressure is maintained, so that water is generated to keep the door in a fully closed state. Furthermore, due to the sudden drop in the water level, the negative pressure in the Zaifuon room suddenly disappeared. Although it is necessary to make the top and bottom width of the hem sufficiently large (-11), it is necessary to make sure that the narrowing valve 26 does not cause an excessive air supply capacity. Adjust before starting to use.
A simple facility can automatically control the predetermined water level, and therefore water diversion, without relying on power and human operations, and can also automatically control water flow during floods. (Since one stop of C power water is provided, it is possible to achieve great economical convenience and to ensure that the entire system is flushed.) Furthermore, the negative pressure of the F phono generated by natural flowing water can be Due to the principle of this machine, which operates automatically by adjusting the water level, the range of applications is extremely wide, such as automatically supplying water to rice fields depending on the water level. , this invention provides great benefits to society.
