Abstract

PROBLEM TO BE SOLVED: To obtain a drainage equipment for rice field that can readily control the sluice level by setting guide rails so as to surround a support and constituting the sluice so that the height position may be adjusted in the height direction with an adjusting mechanism that is integrated to the guide rails. SOLUTION: In the rice field water-drainage equipment that has such a structure that the sluice 4 is supported by the pole installed in the ground, the support pole 5 is surrounded by a tubular guide rail 13 and the sluice 4 is constructed integrally with the guide rail 13 so that the position in the vertical direction may be controlled by an adjusting mechanism 3. In another embodiment, a detachable wedge 32 may be inserted into the gap 17 between the support pole 5 and the guide rail 13.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a paddy field drainage device.

[0002]

2. Description of the Related Art A conventional paddy drainage device has a structure in which a sluice is fixed to a column installed underground.

[0003]

As described above, in the conventional paddy drainage system, the water gate is installed at a fixed height and fixed, so that it is difficult to respond to the water level of the paddy field. Even when relocation was required due to paddy fields, it was difficult to respond.

The present invention provides a paddy drainage system which can be easily adjusted when readjustment of the position of a floodgate is required, and which can easily cope with relocation due to paddy fields. The purpose is to provide.

[0005]

According to the present invention, there is provided a paddy drainage device having a structure in which a floodgate is supported by a column installed in the ground, provided with a small gap surrounding the column. There is provided a paddy field drainage device provided with a pipe-shaped guide rail, wherein the water gate is configured to be integrated with the guide rail and the height position of the support is adjusted by an adjustment mechanism.

[0006] It is possible to provide a fixing device constituted by inserting a removable wedge into a gap between the column and the guide rail.

[0007] A flange may be provided on the support, the adjusting mechanism may be constituted by a bolt and a nut connecting the flange and the guide rail, and the wedge may be provided on the bolt so as to be vertically movable.

[0008] The fixing device may be provided at both upper and lower ends of the guide rail.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an overall configuration of an embodiment of the present invention, and FIG. 3 shows an enlarged view of a main part thereof.
In these figures, the paddy field drainage device includes a solar cell unit 1,
It comprises a control box 2, an adjusting mechanism 3, a floodgate 4 and two columns 5. The solar cell 1 and the control box 2 are for controlling the opening and closing of the water gate 4 by electric opening and closing, and need not be described in detail.

The sluice 4 comprises an outer frame 11, a valve 12, and a pipe-shaped guide rail 13. The valve 12 is controlled to move up and down to open and close a water inlet pipe 15 and a water outlet pipe 16 to the paddy field. Control the area. The valve 12 is provided with a window 14 on the upper surface thereof.

It is sufficient for the guide rail 13 to have a pipe shape, and a plurality of parallel holes in the vertical direction may be provided.

The lower part of the column 5 is installed in the ground, and the pipe-shaped guide rail 13 is provided above the column so as to surround the column. A minute gap 17 is provided between the column 5 and the guide rail 13. This guide rail 13 is the outer frame 1 of the above-mentioned floodgate.
1 and constitute a floodgate 4 together. Also,
The valve 12 is moved up and down by a valve stem 18, and the valve 12 and the valve stem 18 are connected by hinges 19, as shown in FIG.
Consists of two. A flange 23 is fixed to the upper end of the base support 22, and a fixing member 24 having a rectangular cross section is provided at the upper end of the guide rail 13.
5 is provided, and a nut 26 is provided in contact with the flange 23 to constitute the adjusting mechanism 3 for suspending and holding the guide rail 13.

That is, by adjusting the nut 26, the water gate 4 moves up and down, and its position is adjusted. The position of the sluice 4 only needs to be adjusted in this way, and it is possible to use other hanging tools instead of bolts and nuts.

A wedge 32 having a hole is inserted into the bolt 25, and its tip is bent in the direction of the gap 17 and is driven into the gap 17. The insertion of the wedge 32 into the gap 17 is adjusted by another nut 33 provided on the bolt 25, and the guide rail 13 is fixed to the column 5. Thus, one fixing device 31 is configured.

Similarly, a fixing member 24 'having a right-angle cross section, a bolt 25', a wedge 32 'and a nut 33' are provided on the lower end side of the guide rail 13, so that the guide rail 13 is more securely fixed to the support 5. It is assumed. In this manner, another fixing device 31 'is configured.

As described above, the two props 5 are buried in the ground, and the sluice 4 is held by the pipe-shaped guide rail 13. Adjust the level of the position. A wedge 32 is driven into a gap 17 formed between the support 5 and the guide rail 13 to securely fix the sluice 4 to the support 5. The wedge 32 can be omitted according to local circumstances.

[0018]

As described above, since the water gate level adjusting mechanism is provided, it is possible to immediately cope with the need to readjust the water level of the paddy field. In addition, even if it is necessary to relocate a paddy drainage device due to paddy fields, the water gate can be removed from the column very easily, which makes it easy to deal with.
