Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a riverbed height measuring device,
Particularly, the present invention relates to a riverbed height measuring device for measuring the depth of a riverbed in a torrent water area.

[0002]

2. Description of the Related Art In conventional river bathymetry, a ship is used to simultaneously observe ship position, tide level, water depth, etc., and make a cross-section diagram and a depth map. In the case of a machine with a length of less than 3 meters, a red scale was used.

[0003]

However, the flow of water at the front of the integrated cooling water discharge port of a nuclear power plant or a thermal power plant is a torrent, which makes it impossible to measure by a ship due to waves and swells, And the ship's crew was dangerous.

[0004] In addition, surveying is also possible using large-sized cleans fixed on both banks of the river, but large-sized cleans cannot be operated on public roads as it is, so that large-sized cleans must be assembled and disassembled. And personnel are required, and the use of Clen bathymetry requires enormous costs.

Further, in a torrent water area or shallow water, an acoustic sounder cannot accurately measure the water depth due to bubbling or scattering or poor transmission of sound waves due to a dense turbid state. I did not endure.

The present invention has been made to eliminate the above disadvantages.

A depth-measuring wire 6 whose other end is suspended downward through the transverse pulley 5, a lead weight, for example, 10 kg red 7 fixed to the other end of the depth measuring wire 6, Is fixed to the transverse pulley 4, and the other end is constituted by a scaled moving and side-distance wire 8 led to each of the two banks.

As shown in FIGS. 4 to 8, the red 7 has a streamlined body portion 9, a cross-shaped tail portion 10 provided at the rear of the body portion 9, and a rear portion of the tail portion 10. U-shaped mounting section 11 fitted into upper vertical plate 10a from above
a, the horizontal tail 11b, and the vertical tail 11c, the vertical slots 12 respectively provided on both side plates of the mounting portion 11a of the horizontal tail 11, and the slots of the horizontal tail 11 12, a through hole 13 provided in the upper vertical plate 10 a of the tail portion 10 at a position corresponding to 12, a fixing bolt 14 passing through the long hole 12 and the through hole 13, and a bottom portion of the mounting portion 11 a of the horizontal vertical tail 11. 11d and tail 1 above
Wedge-shaped tapered sheet pile 1 for angle adjustment in which the horizontal tail fin 11b interposed between the upper surfaces of the upper vertical plate 10a is inclined by 5 degrees with respect to the horizontal plane so that the front part is higher than the rear part.
5, a through hole 16 vertically penetrating the body portion 9 from above, a through hole 17 crossing the through hole 16 and horizontally penetrating the body portion 9 from the side thereof, and the through hole The other end of the water depth measuring wire 6 is inserted into the through hole 16 and is fixed to the pin 18 inserted into the through hole 17.

Since the riverbed height measuring apparatus of the present invention is configured as described above, a reference point at which the water depth measurement on the bathymetric surveying line of the river 1 is started is set by transit or the like, and as shown in FIG. The transverse pulley 4 is moved and fixed on the cableway wire 4 by the moving / ranging wire 8 so that the red 7 of the water depth measuring wire 6 is located on the reference point, and the red 7 is placed in the water. The water depth measurement wire 6 is extended until it sinks and lands on the water bottom.

At this time, even in a torrent area, the red 7 does not move left and right by the vertical tail unit 11c.
The horizontal tail unit 11b allows the vehicle to land horizontally on the riverbed without being shaken back and forth.

In this state, the water depth measuring wire 6 is provided by the water depth measuring wire level measuring machine 19 provided on the shore.
Is read, and the height of the riverbed is calculated using the leveling calculation method based on the position of the level measuring machine 19 and the scale.

After the above measurement, as shown in FIG. 9, the red 7 of the water depth measuring wire 6 is moved to the next measuring position in the width direction of the river 1 by the moving and side distance wire 8. The transverse pulley 4 is moved to one vehicle side and fixed, and the water depth measuring wire 6 is expanded and contracted, and the red 7
At the bottom of the water, the scale of the depth measuring wire 6 is read by the depth measuring wire level measuring device 19 provided on the shore in the same manner as above, and the level measuring device 1
The height of the riverbed is calculated using the scale 9 and the above scale, and red is sequentially moved from the other vehicle toward the one vehicle to complete the bathymetric survey of one horizontal row of the river.

After the bathymetric surveying of the river is completed, the winch 3 of the vehicle 2 on both banks is operated to loosen the cableway wire 4 stretched between the vehicles 2 and 2 and the water depth is measured. The measurement wire 6 and the red 7 are pulled out of the water, the outrigger of the vehicle is released, and the vehicle 2 is released.
Is moved along the next bathymetric survey route, vehicles are fixed on both banks in the same manner as above, and crossing bathymetric survey of rivers is performed sequentially.

FIGS. 10 and 11 show another embodiment of the red of the present invention. In this embodiment, a red 20 is used, and the red 20 is attached to a spherical body 21 and a tail of the body 21. The surface is fixed to the spherical body 2
A horizontal / vertical tail 22 comprising a horizontal tail 22 a extending in a radial direction from the vertical tail 22 and a vertical tail 22 b perpendicular to the horizontal tail 22, and a ring-shaped fixture 23 for fixing the water depth measuring wire 6 provided on the upper part of the body 21. It consists of.

In this embodiment as well, the red 20 can be landed horizontally on the bottom of the water without being shaken right and left by the vertical tail 22b and also by the horizontal tail 22a even in a turbulent water area. .

The horizontal tail 22a may be inclined if it can be freely tilted.

[0024]

As described above, according to the riverbed height measuring device and its red of the present invention, the safety is high, the construction is quick,
There is a great benefit of low construction costs.

Further, since a red having a curved surface and a weight capable of withstanding the water flow resistance is used and a horizontal and vertical tail is provided, for example, in a river having a flow velocity of 2 to 3 m / sec, the conventional red is 1 m in the left-right direction. The red of the present invention hardly oscillated in the left-right direction, but it oscillated by about 5 cm in the front-back direction. There is a great advantage that it can land correctly on the river bottom without swinging and flowing in the direction of flow, and can accurately measure sounding.
