DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for collecting ooze (sludge) collected in a port or a lake.

[0002]

2. Description of the Related Art In a conventional ooze collecting apparatus, as shown in FIG. 4, a frontage of an apparatus body 11 is widened in order to increase the amount of sewage per unit time (increase the capacity). .

[0003]

However, the apparatus body 1
When the frontage 1 is widened, if the water bottom A 'has undulations or inclinations, when the gap B between the front end opening 19 of the apparatus main body 11 and the water bottom A' becomes large, the upper part of the suction port is partially exposed to water,
There is a problem that the water is sucked in from here, and the mud content is easily reduced as compared with the small-capacity ooze collecting apparatus 10 ″ having a narrow frontage. It is necessary not only to widen the frontage, but also to take measures to prevent the size of the frontage from affecting the performance of the apparatus.

[0004]

According to a first aspect of the present invention, there is provided an ooze collecting apparatus according to the present invention, which divides the inside of the apparatus into a plurality of units each having a narrow opening, and independently controls the suction amount of the ooze for each unit. Is characterized by the following: In this way, the inside of the device main body is divided into a plurality of units with narrow frontage, and the suction amount of ooze is controlled independently for each unit. Not, but high mud content
(Dredge).

[0005]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1 to FIG. 3, reference numeral 10 denotes an ooze collecting apparatus. In the ooze collection apparatus 10, the inside of an apparatus main body 11 is divided into a plurality of units 13 having a narrow frontage by a partition wall 12.

[0006] Each unit 13 is provided with a fluidized blade 14 that is forcibly driven. Further, behind the fluidizing blade 14, a suction chamber 1 having a suction port 15 at a lower portion is provided.
6 are provided. The suction chamber 16 is provided with a flow control type suction pump 17 and a duct 18 communicates with the suction chamber 16. On the other hand, on the ceiling 20 of the front end opening 19 of each unit 13,
A flap type mud sensor 30 is attached. The mud sensor 30 traces the surface A of the sediment with the flap 31 and measures the fluctuation of the surface A of the sediment with a potentiometer 33 attached to the rotation shaft 32.

A controller 40 increases the flow rate of the suction pump 17 when the gap H between the sedimentary mud surface A and the main body ceiling 20 is small. When a part of 15 is directly exposed to water, the flow rate of the suction pump 17 is reduced. If the suction pump flow rate is reduced, the amount of inflow mud exceeds the amount of suction mud, the mud accumulates in front of the suction port, the level of mud rises, the gap H decreases, and the level of mud rises from the upper end of the suction port 15. Rises upwards, and only the mud can be sucked, and mud with a high mud content can be collected.

When the above-mentioned ooze collecting device 10 advances, the unevenness of the sedimentary mud surface A is measured by the flap type mud sensor 30. In the unit 13 where the gap H between the sedimentary mud surface A and the main body ceiling 20 is small, the suction pump 17 is used. Is increased, the gap H is large, and in the unit 13 in which a part of the suction port 15 is directly exposed to the water, the flow rate of the suction pump 17 is reduced. As a result, initially, the unit 1 having a large gap H between the surface A of the sedimentary mud and the ceiling 20 of the main body.
Also in 3, the mud level in front of the suction port is adjusted, so that a large amount of water is not sucked, and the mud content of the apparatus body is improved. In addition,
The mud sensor 30 may be another ultrasonic type without being limited to the flap type.

[0009]

As described above, the present invention is characterized in that the inside of the apparatus main body is divided into a plurality of units having a narrow frontage, and the suction amount of the soft mud is controlled independently for each unit. Even if the frontage of the main unit is widened, it is not affected by the topography of the water bottom, and mud sampling (dredge) with a high mud content becomes possible.
