Description

[Detailed description of the invention] The present invention relates to a floating type selective water intake device that is capable of taking in middle-layer water and surface water at appropriate depths such as ponds and marshes. be.

When taking surface water or mid-layer water from a pond or pond for use as water for irrigation or fish farming, a float is installed at the upper end of a retractable water intake pipe erected from the bottom of the pond, and this float is used to take in the surface water. If the water is floated above the pond and taken in from the intake port at the top of the water intake pipe, relatively warm surface water can be constantly taken in. In addition, for intake of mid-layer water, normally a horizontal intake pipe is laid that opens into a mid-to-high area such as a pond, and the water is taken from the opening at the tip of this intake pipe. Since it is fixed horizontally, surface water may be taken in due to changes in water level, so something that can take in mid-layer water at a certain depth is desired.

The present invention has been developed in view of the above points, and will be explained in detail below with reference to drawings which are examples.

On a foundation provided at the bottom of a pond, an expandable water intake pipe 3 with a water intake board 2 installed horizontally at the upper end is erected through the foundation, and a connecting plate 4 is placed on the water intake board 2 at the upper end of the water intake pipe 3. A horizontal straightening board 5 is connected between the water intake board 2 and the straightening board 5.
The lower end of the cable or shaft 10 hanging from the hoist 9 on the float 8 floated above the pond water 7 is rectified. A guide arm 1 connected to the central part of the board 5 and having rollers 11 and 11' at the tip from the peripheral side of the water intake board 2 and the float 8.
rollers 11, 11' at the tips of the guide arms 12, 14 are brought into contact with the inner surface of a guide column 15 erected on the foundation so as to be able to roll up and down; The lower surface 13 of the rectifying plate 5 has a tapered portion 19 corresponding to the tapered upper plate 21 protruding from the periphery of the rectifier plate 5 .
In the present invention, the above-mentioned "gap 20" is defined by the taper upper plate 21 of the rectifier plate 5, the upper wall 23 connected thereto and tapered at the same angle, and the lower wall of the water intake 6, as shown in FIG. The bottom walls 22 are each tapered at a predetermined angle to form a predetermined gap, thereby facilitating water intake.
The height of 0 is about 1 to 2 meters, and its upper plate 2
The taper angle θ between the lower wall 22 and the horizontal plane is θ≒20° to 25°, and the taper angle φ between the bottom wall 22 and the horizontal plane is φ≒15° to 20°<θ.

The present invention consists of the above-mentioned structure, and the water intake 6 is connected between the horizontal water intake plate 2 at the upper end of the water intake pipe 3 and the rectifier plate 5 installed on the water intake plate 2 via the connecting plate 4. It is used to take in water from the pond water 7, but in the case of taking mid-layer water, the hoisting machine 9 on the float 8 floated above the pond water 7 is operated, and the rope from the hoisting machine 9 is Alternatively, the straightening board 5 connecting the lower end of the shaft 10 is raised and lowered together with the water intake board 2 at the upper end of the water intake pipe 3, and is positioned at a desired depth in the pond.

After doing this, when water intake from the water intake port 6 between the water intake board 2 and the rectifier board 5 is started, the pond water 7
Even if the water level of Move, intake pipe 3
expands and contracts, so that middle-layer water at a desired constant depth can always be taken from the water intake port 6.

In the present invention, the lower surface 13 of the float 8 has a tapered portion 19 having a taper angle approximately the same as the taper angle θ of the tapered upper plate 21 protruding from the periphery of the rectifier plate 5. In order to take in water, the rectifier plate 5 is moved to the position shown by the two-dot chain line in FIG.
When the float 8 is raised to a position where it contacts the lower surface 13, the taper portion 19 of the lower surface 13 of the float 8 and the rectifier plate 5
The tapered upper side plate 21 of the taper is brought into substantially close contact with the taper upper plate 21, which has the effect of preventing the generation of turbulent flow at this point when taking in surface water and smoothing the inflow of surface water into the water intake port 6. It is something. Furthermore, since the hoist 9 is provided on the float 8, the position of the water intake board 2 can be controlled by remote control, which is an advantage in terms of handling and operation.
