As shown in Fig. 1, generally, the ship 1 is generally provided with a ballast tank 2 filled with BW (3) for maintaining the stability of the ship during ball flight.

The detailed structure of the ballast tank 2 according to this conventional technique is described in detail, for example, in Korean Patent Laid-Open No. 10-2010-84032 entitled " Method for automatically controlling the net suction of ballast pumps in ballast water automatic exchange & (Hereinafter referred to as " ballast tank ") (published on Dec. 7, 2010), Korean Patent Laid-Open No. 10-2012-118166 Tank structure) (issued October 26, 2012).

When the time for loading cargo arrives, the BW 3, which is filled in the ballast tank 2, is subjected to a process of being discharged to the outside. At this time, the BW 3 is provided with a ballast tank (3) is released without proper control of this chemical, because of the addition of a series of chemicals (for example, oxidizing agents) to neutralize the pollution, The seawater is contaminated by chemical agents.

In view of such a problem, as shown in Fig. 1, the side of the ship operator is branched / installed on a part of the BW distribution pipe 4, and then the BW distribution A measure is taken to collect the sample BW in the BW flowing through the pipe 4 and to measure the concentration of the sample BW thus sampled through the chemical concentration measuring instrument 6 so that the concentration of the BW discharged to the outside of the vessel 1 (In this situation, if it is judged that the content concentration of the chemical contained in the sample BW exceeds the appropriate level, for example, at the ship operator side, Additional measures, such as a neutralizer injection procedure, will take steps to reduce the concentration of chemical in the BW).

Under such a conventional system, the BW flowing through the BW circulation pipe 4 maintains a very high flow rate. However, in spite of this situation, since the side piping 5 is simply branched / installed in a part of the BW circulation pipe 4 without taking any measures in the past, most of the BW flowing through the BW circulation pipe 4 It is not branched to the side piping 5 or the chemical concentration measuring instrument 6 but causes a serious problem of continuously maintaining only the straight forward flow on the BW circulation pipe 4.

Of course, under such a problem, the vessel operator had to suffer a lot of difficulty in sampling the sample BW, and as a result, it was difficult to control the concentration of the chemical contained in the BW.

Korean Patent Laid-Open No. 10-2010-84032 (Title: Automatic adjustment method of the net suction of ballast pump during automatic exchange of ballast water) (2010.7.23 released) Korean Patent Laid-Open No. 10-2010128054 (Name: Ballast Tank of Ship) (Dec. 7, 2010) Korean Patent Laid-Open No. 10-2012-118166 (Name: Ballast Tank Structure of Ship) (2012. 26, 2012)

Therefore, an object of the present invention is to provide a sample BW sampling apparatus having a curved guide end for guiding the effective introduction of the sample BW and an open hole for sampling BW on a BW flow path defined by a BW (Ballast Water) A sufficient amount of sample BW can be branched or introduced into the chemical concentration measuring apparatus side flexibly even under a situation where the flow rate of BW flowing through the BW circulation pipe is fast, It is easy to guide the sampling process of sample BW as well as BW chemical concentration control procedure without any difficulties on the side of ship operator.

Other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

In order to achieve the above object, in the present invention, in a state in which a part of a BW circulation pipe connected to a ballast tank storing ballast water (BW) is installed, a sample BW is sampled among BW flowing through the BW circulation pipe A sample BW sampling device comprising: a distribution pipe branch frame branched from a part of the BW distribution pipe; A curved guide end portion for guiding the inflow of the sample BW and an open hole for sample BW withdrawal installed on the BW flow path defined by the BW flow pipe in a state of passing through the distribution pipe branch frame And a sample BW sampling pipe which, in one state, provides a sampling path of the sample BW.

In the present invention, on a BW flow path defined by a BW (Ballast Water) flow pipe, a sample-BW-specific flow pipe systematically provided with a curved guide end for guiding the effective introduction of the sample BW and an open hole for sample BW- A sufficient amount of sample BW can be flexibly applied to the chemical concentration measuring apparatus side even under a situation where the flow rate of BW flowing through the BW circulation pipe is high at a ship operating subject side under the implementation environment of the present invention So that the process of collecting the sample BW as well as the process of adjusting the concentration of the chemical contained in the BW can be effectively carried out without any difficulty.

Brief Description of the Drawings Fig. 1 is an exemplary view conceptually showing a sample BW sampling procedure according to a conventional technique. Fig.
Fig. 2 is an exemplary view conceptually showing a sample BW sampling procedure according to the present invention; Fig.

Hereinafter, a sample BW sampling device according to the present invention will be described in more detail with reference to the accompanying drawings.

2, when the loading time of the cargo arrives, the BW 13, which has been filled in the ballast tank 12, undergoes a process of being discharged to the outside. At this time, the BW 3), because of the addition of a series of chemicals (for example, oxidizing agents) to neutralize the contamination of the ballast tank, if the BW 13 is released without proper control of the chemical, The sea water in the vicinity of the ship 11 is inevitably confronted with serious problems such as contamination by chemicals.

Of course, in consideration of such a problem, the ship operator mainly collects the sample BW in the BW flowing through the BW circulation pipe 14, measures the concentration of the sampled BW through the chemical concentration measuring instrument 16 The concentration of the chemical contained in the BW discharged to the outside of the vessel 11 is controlled so as to be controlled at an appropriate level or lower (for example, under this condition, the concentration of the chemical contained in the sample BW is appropriately controlled , The ship operator will take measures to reduce the chemical concentration of the BW, for example, through additional measures such as neutralizing agent input procedures).

Under such a system of the present invention, since the BW flowing through the BW circulation pipe 14 maintains a very high flow rate, if no further action is taken, most of the BW flowing through the BW circulation pipe 14 is measured by the chemical concentration It is not branched to the side of the device 16 but causes a serious problem of continuously maintaining only the straight-type high-speed flow on the BW flow pipe 14.

Under such a sensitive situation, in the present invention, a sample BW sampling device 20 unique to the present invention for guiding the effective introduction of the sample BW into the part of the BW circulation pipe 14 connected to the ballast tank 12 is additionally provided I will take measures.
