Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a water gate with a two-stage door installed in a river, particularly a water level adjustable water gate having a device for engaging and disengaging an upper door and a lower door. Regarding.

[Conventional technology]

Conventionally, two-stage gates have been known as water gates that can adjust the water level when the water is full. Figures 10A to 10 schematically show different states of conventional two-stage gates. FIG.
The lower rR102 is integrally attached to the 01, and the upper 5t1
03 is provided in the frame 101 so as to be slidable relative to the lower lIO2, and the upper door 103 is driven by an elevating shaft 104.

The frame 101 is provided with upper and lower stoppers 105 and 106 that regulate the upper and lower limits of movement of the upper door 103. Note that 107 is a water gate bottom, and 108 is a groove formed in the water gate bottom 107.

In this conventional two-stage nose type water gate, when used in a half-water level state, the lower door 102 and the upper door 103 are overlapped, and the lower end of the lower 8102 is connected to the water gate bottom 107. When the upper door 103 is used at full water level, the upper door 103 is pulled up by the lifting shaft 104 so that the lower end of the lower ft 1102 is in close contact with the groove 108 as shown in FIG. The door 102 and the upper door 103 are in a misaligned state.

In addition, when pulling up both doors, if the elevator shaft 104 is further pulled up, the upper end of the upper door 103 comes into contact with the upper bar 105 of the frame 101, and the upper door Lower door 102 integrated with frame 101 together with 103
rises and becomes fully open as shown in the 10th diagram.

[Problem that the invention seeks to solve]

However, the conventional two-stage nose type water gate shown in Fig. 1O has the following problems.

(1) In the event of an emergency such as a rise in water due to rain, it takes time to fully open the flood gates, making it difficult to take prompt action.

That is, for example, in order to change the water gate from the half-water level state shown in FIG. 10 to the fully open state shown in FIG.
It is necessary to bring the upper end of the water gate 3 into contact with the upper stopper 105, and the conditions shown in FIGS. 10B and 10C must be passed, so it takes time to fully open the water gate.

(ii) The moving distance of the elevating shaft 104 becomes longer, leading to an increase in operation time, and it is necessary to secure a wide space necessary for moving the elevating shaft 104.

For example, if the heights of the upper door 103 and the lower door 179102 are the same, from the half-water level state shown in FIG.
In order to reach the fully open state shown in the figure, a moving distance three times the height of the doors 102 and 103 is required.

(iii) It takes time to close the water gate.

When closing the water gate, the lower end of the lower door 102 is connected to the water gate bottom 1.
It must be in close contact with the groove 108 of 07, but if 4108 is clogged with earth and sand, the lower door 1
02 and the frame body 101 alone cannot bring the lower end of the lower door 102 into close contact with the guide 108. For this reason, it is necessary to apply pressure to the lower 5t102 from above, but for example, in order to change from the fully open state shown in Fig. 10 to the full water level state shown in Fig. 10B, the pressure is shown in Figs. 10C and 10B. Through the states, as shown in FIG. 10A,
The upper door 103 is pressed from above by the lifting shaft 104, and the upper door 103 is pressed from above.
By bringing the lower end of the lower part 103 into contact with the lower stopper 106 of the frame 101, the lower end of the lower part 102 is brought into close contact with the groove 108 via the frame 101, and then the upper m103 is pulled up again, as shown in Figure 1O, B. must be in a state. However, regardless of whether the water level is half-filled or full, the lower 5t102 must be lowered once to the lower limit position, which takes extra time.

An object of the present invention is to provide a water level adjustable water gate that can solve the above problems.

[Means for solving problems]

Bar 5
The positional relationship between the first rack rod 5 and the operating device 10 is fixed.

[Effect]

Hereinafter, the operating procedure of the water level adjustable water gate having the above configuration will be explained.

As shown in FIG. 7, when the upper door 2 and the lower door 3 are overlapped and both doors 2.3 are at the lower limit, when the water gate is to be fully opened in an emergency, the locking pin 30 of the operating device 10 is pressed.
When the is pulled out from the operation frame 27 and the handle 29 is pulled down, the entire operation device 10 is lowered relative to the first rack rod 5, and the operation rod 23 is lowered along the first rack rod 5. Interlockingly, the plate-like bodies 24, 25 and link rods 26 descend as shown by solid lines in FIG. 7, and the crack plate 22
rotates clockwise in the figure around the shaft 20, and the rack engagement pin 19 that has engaged with the crack plate 22 moves to the left in the figure, and the rack pin 8b of the second rack rod 8 and the rack engagement pin 19 can be engaged with the engagement/disengagement device 9.
becomes a cohesive state. That is, the crack plate 22 acts as a driving direction changing means. In addition, in this state, the locking pin 30
is reinserted into the operating frame 27 so that the relative positions of the operating device 10 and the first rack rod 5 do not shift.

In this state, when the first rack rod 5 is raised by the lift drive device 6, the operating device 10 and the entire engagement/disengagement device 9 rise, and the upper door 2 fixed to the engagement/disengagement device 9 rises. At the same time, the rack engaging pin 19 comes into contact with the rack pin 8b of the second rack rod 8, and the lower door 3 connected to the second rack rod 8 also rises. Therefore, from the state in which the upper door 2 and the lower door 3 are stacked together, both doors can be directly raised as one, and the water gate can be quickly brought into a fully open state. In other words, there is no need to wait until the upper end of the upper door 2 comes into contact with the upper stopper 14a of the frame 11 as in conventional water gates.

Also, when the lower door 3 is brought into close contact with the water gate bottom 13, the upper fi
No matter what the positional relationship between i2 and the lower door 3 is, if the locking/separating device 9 is brought into the locking state as described above in that state, the positions of the upper door 2 and the lower door 3 will be Since the relationship is fixed, the first rack rod 5 is moved by the lifting drive device 6 in this state.
By lowering, the upper m2 and lower door 3 are lowered together, and the lower end of the lower door 3 can be quickly brought into close contact with the water gate bottom 13. In other words, like a conventional water gate, the upper R2
It is not necessary to raise the upper door 2 to a desired height again after bringing the lower end of the door into contact with the stopper 14 of the frame 11.

In addition, when changing the positional relationship between the upper door 2 and the lower door 3, pull out the locking pin 30 of the operating device 10 from the operating frame 27,
When the handle 29 is pulled up, the operating rod 23 rises, and in conjunction with this, the plate-like bodies 24, 25 and the link rod 26 rise as shown by broken lines in FIG. The rack engagement pin 19 rotates counterclockwise in the figure and engages with the long groove 22a of the crack plate 22, and moves to the right in the figure, causing the rack pin 8b of the second rack rod 8 and the rack engagement pin 19 to engage with each other. The attachment is released and the attachment/detachment device 9 enters the detached state. Note that the locking pin 30 is attached to the gravel harvesting frame 27.
to prevent the relative positions of the operating frame 27 and the operating rod 23 from shifting.

Therefore, if the first rack rod 5 is raised by the lift drive device 6 in this state, only the upper door 2 will rise, and by stopping the lift drive device 6 at a desired position, the amount of overlap between the upper door 2 and the lower R3 will be increased. can be adjusted. Handle 2 after adjustment
9 is pulled down, the rack engaging pin 19 is passed through between the rack pins 8b at a predetermined position, so that the relative position between the upper FR 2 and the lower door 3 can be fixed. Therefore, the upper door 2 and the lower door 3 can be fixed in any overlapping state, and the water gate can be opened and closed while the height of both doors of the water gate is fixed at the desired height. If the water level is predetermined, there is no need to set the height of both gates each time the gate is opened and closed, improving operability.

〔Effect of the invention〕

As described above, according to the present invention, the following effects can be obtained.

(i) Regardless of the state of overlap between the upper and lower doors,
Both doors can be immediately raised as one, so
Even if there is an urgent need to spray water due to an increase in water due to rain, etc., it can be quickly responded to.

(11) Since the lower door can be brought into close contact with the bottom of the water gate without lowering the upper door to the lower limit position, the door can be quickly closed.

(iii) The water gate can be opened and closed while keeping the height of both doors of the water gate constant, improving operability.

(1v) Since the operating rod that operates the locking and separating device for the upper door and the lower door moves along the first rack rod, no extra space is required to operate the separating device. I never touch the preparation.

(V) It is easy to operate and can be engaged and detached at two points.

(vi) The moving distance of the descending shaft is shortened, and less space is required for moving the raising and lowering shaft.
