Description

  The present invention relates to a water sampler for collecting good sample water by preventing impurities from being mixed in a relatively shallow water area such as the sea (inner bay, coast, etc.), lakes, dams, rivers and the like.

  As a prior art related to a water sampler, for example, Patent Document 1 (title of invention: simultaneous multilayer water sampler) is disclosed. In the simultaneous multilayer water sampler of Patent Document 1, a weight is attached to the lower end of a water sampling cell connected in series at a predetermined water sampling interval, and the weight is settled with another rope, and then the rope on the upper end of the water sampling cell.

The intermediate water sampling valve 110 opens and closes the intermediate flow path 105.
The outlet sampling valve 111 opens and closes the outlet channel 107.

The operation unit 300 is a specific example of the control drive unit, and controls the opening and closing of the introduction water sampling valve 109, the intermediate water sampling valve 110, and the outlet water sampling valve 111, respectively. For example, the operation unit 300 may be automatically operated by a computer device, or may be manually operated by a human by a switch operation. Details of the control will be described later.
The water sampler 1 has such a configuration.

Then, the usage method of the water sampling device 1 is demonstrated. 2 is an explanatory view for explaining an example of use of the water sampler of the present embodiment, FIG. 3 is an explanatory view of a winch, FIG. 4 is an explanatory view of a water sampling operation, FIG. 4 (a) is a first operation diagram, FIG. 4B is a second operation diagram, and FIG. 4C is a third operation diagram.
This use example is based on the premise of collecting sample water from the sea area. The operation unit 300 is manually operated by a switch.

  In such a usage example, in addition to the water sampling device 1 including the water sampling unit 100, the signal line 200, and the operation unit 300, the rope 400, the weight 500, the winch 600, and the boat 700 are used. First, the boat 700 moves to a predetermined sea area and starts sampling at that point. In the water sampling unit 100 of the water sampler 1, the introduction water sampling valve 109, the intermediate water sampling valve 110, and the outlet water sampling valve 111 are closed, and the winch 600 is operated in this state to collect water. Unit 100 is thrown into the water.

  As shown in FIG. 3, the winch 600 includes a feeding drum 601, a traverser 602, a drive control unit 603, a lifting arm 604, a pulley 605, and the like. The rope 601 is rotated at a constant rotation speed, and the rope 400 is fed out and supplied. A weight 500 is connected to the tip of the rope 400, and the rope 400 sinks while maintaining the state where the rope 400 is always stretched. Further, the rope 400 is considered to be able to move smoothly in the lateral direction by the traverser 602 and in the vertical direction by the pulley 605 provided at the tip of the lifting arm 604.

  In this way, the weight 500 sinks to a predetermined depth in the sea area with the rope 400 stretched out. The water sampling unit 100 is connected in the vicinity of the weight 500, and the water sampling unit 100 also sinks into the deep sea. At this time, the signal line 200 is also fed out by a drum (not shown). Then, when the target depth is reached by a depth meter or the like, the winch 600 is stopped and water sampling is started.

Subsequently, the operator operates the operation unit 300.
First, when the operator operates the operation unit 300 to open the introduction water sampling valve 109, the operation unit 300 performs drive control to open the introduction water sampling valve 109. Then, seawater is introduced from the introduction port 102 by water pressure, and seawater flows into the entire interior of the introduction flow path 103 and the main sample container 104 until the internal pressure of the main sample container 104 reaches an equilibrium state. Thereby, the inside of the introduction flow path 103 and the main sample container 104 is wash | cleaned with seawater, and there can exist the same effect as performing co-washing. After a while, as shown in FIG. 4A, an air reservoir is formed by the compressed air 800 on the upper side of the main sample container 104, and the sample water 900 is contained in the lower main sample container 104 and the introduction channel 103. Stable when filled.

  Subsequently, when the operator operates the operation unit 300 so as to open the intermediate water sampling valve 110, the operation unit 300 performs drive control so as to open the intermediate water sampling valve 110. Then, seawater is further introduced from the inlet 102 by water pressure, and the introduction channel 103, the main sample container 104, the intermediate channel 105, and the sample for washing are washed until the internal pressure of the sample vessel for washing 106 reaches an equilibrium state. Seawater flows into the entire interior of the container 106. Thereby, the inside of the introduction flow path 103, the main sample container 104, the intermediate flow path 105, and the sample container for washing 106 is washed with seawater, and the same effect as that obtained by washing together can be obtained. In particular, the introduction channel 103 and the main sample container 104 have the same effect as when the entire surface is completely washed again with seawater and washed again. Further, the contaminated seawater remaining after the first washing is washed away to the washing container 106 by this washing. Here, the volume of the sample container 106 for washing is larger than the volume of the main sample container 104 so that all the sample water accumulated in the main sample container 104 is sent to the sample container 106 for washing. Therefore, consideration is given so that the contaminated sample water does not remain in the main sample container 104. After a while, as shown in FIG. 4B, an air reservoir is formed by compressed air 800 on the upper side of the sample container 106 for washing, and the lower washing sample container 106, the intermediate channel 105, the main channel 105, The sample container 104 and the introduction flow path 103 are stable when the sample water 900 is filled.

  Subsequently, when the operator operates the operation unit 300 so as to open the derivation sampling valve 111, the operation unit 300 performs drive control so as to open the derivation sampling valve 111. Then, seawater is further introduced from the introduction port 102 by water pressure, and the seawater flows into the entire interior of the introduction channel 103, the main sample container 104, the intermediate channel 105, the co-washing sample container 106, and the outlet channel 107. Compressed air is discharged from 108. As a result, the introduction flow path 103 and the main sample container 104 have the same effect that the water remaining on the entire surface of the introduction channel 103 and the water contaminated by the washing together are completely discharged to enhance the washing effect. After a while, as shown in FIG. 4C, the outlet channel 107, the sample container for washing 106, the intermediate channel 105, the main sample container 104, and the introduction channel 103 are filled with the sample water 900. It stabilizes at.

Then, the operator operates the operation unit 300 so as to close at least the introduction water sampling valve 109 and the intermediate water collection valve 110, and drive control is performed so that the operation unit 300 closes the introduction water collection valve 109 and the intermediate water collection valve 110. To do. In this case, drive control is performed to simultaneously close the introduction water collection valve 109 and the intermediate water collection valve 110, or after closing either one of the introduction water collection valve 109 or the intermediate water collection valve 110 for a while. It is good also as control which closes the other. As a result, the sample water is trapped in the main sample container 104 and collected.
Thereafter, the winch 600 is operated to pull up the water sampling unit 100 and the water sampling is completed.

The water sampler 1 of this embodiment has been described above. In the case where the previous operation unit 300 is not a manual switch but a portable computer device or the like, a series of operations may be automatically performed continuously with an appropriate period in between.
In such a water sampling device 1, since the sample container 106 in the water sampling unit 100, which was impossible in the past, was realized, high-quality sample water can be obtained, and high-precision inspection is possible. Become.

The lead-out water sampling valve control line 214 connects the lead-out water sampling valve 164 and the operation unit 300 ′.

The operation unit 300 ′ is a specific example of the control drive unit, and controls opening and closing of the introduction water sampling valve 161, the first intermediate water sampling valve 162, the second intermediate water sampling valve 163, and the outlet water sampling valve 164, respectively. . For example, the operation unit 300 ′ may be automatically operated by a computer device, or may be manually operated by a human by a switch operation. Details of the control will be described later.
The water sampler 1 ′ has such a configuration.

  Subsequently, the use of such a water sampler 1 'will be described. In the water sampling unit 100 ′ of the water sampling device 1 ′, the introduction water sampling valve 161, the first intermediate water sampling valve 162, the second intermediate water sampling valve 163, and the outlet water sampling valve 164 are closed. It is thrown into the water in the state. And the winch 600 will be stopped and water sampling will start in seawater.

  First, the operator operates the operation unit 300 ′ so as to open the introduction water sampling valve 161. The operation unit 300 ′ controls driving so as to open the introduction water sampling valve 161. Then, seawater is introduced from the inlet 152 by the water pressure, and the seawater flows into the entire interior of the introduction channel 153 and the main sample container 154 until the internal pressure of the main sample container 154 reaches an equilibrium state. The same effect as that performed can be achieved. After a while, an air reservoir is formed by compressed air on the upper side of the main sample container 154, and the main sample container 154 and the introduction flow path 153 on the lower side are stabilized in a state where the sample water is filled.

  Subsequently, when the operator operates the operation unit 300 ′ so as to open the first intermediate water sampling valve 162, the operation unit 300 ′ controls driving so as to open the first intermediate water sampling valve 162. Then, seawater is further introduced from the introduction port 152 by water pressure, and the introduction flow path 153, the main sample container 154, the first intermediate flow path 155, and the common flow path until the internal pressure of the sample container for washing 156 reaches an equilibrium state. Seawater flows into the entire interior of the sample container 156 for washing. Thereby, the inside of the introduction flow path 153, the main sample container 154, the first intermediate flow path 155, and the sample container for washing 156 is washed with seawater, and the same effect as that obtained by washing together can be obtained. In particular, the introduction channel 153 and the main sample container 154 have the same effect as when the seawater is completely touched on the entire surface and washed again. Further, the contaminated seawater remaining by the previous washing is all washed away into the washing container 156 by this washing. Here, the volume of the sample container for washing 156 is larger than the volume of the main sample container 154 so that all the sample water accumulated in the main sample container 154 is sent to the sample container for washing 156. Therefore, consideration is given so that the contaminated sample water does not remain in the main sample container 154. After a while, an air pool is formed by compressed air on the upper side of the sample container 156 for washing, and the sample container 156, the intermediate channel 155, the main sample container 154, and the introduction channel 153 on the lower side of the sample container 156 Stable when filled with water.

  Subsequently, when the operator operates the operation unit 300 ′ so as to open the second intermediate water sampling valve 163, the operation unit 300 ′ controls driving so as to open the second intermediate water sampling valve 163. Then, seawater is further introduced from the introduction port 152 by water pressure, and the introduction flow path 153, the main sample container 154, the first intermediate flow path 155, and the co-washing are performed until the internal pressure of the precision co-washing sample container 158 reaches an equilibrium state. Seawater flows into the entire interior of the sample container 156, the second intermediate flow path 157, and the sample container 158 for precision co-washing. As a result, the inside of the introduction channel 153, the main sample container 154, the first intermediate channel 155, the sample container for washing 156, the second intermediate channel 157, and the sample container 158 for precision washing is washed with seawater. The same effect can be obtained as in the case of co-washing. In particular, the inside of the introduction channel 153 and the main sample container 154 has the same effect as seawater is completely touched on the entire surface and rewashed again. In addition, the seawater in the main sample container 154 is washed away to the sample container 156 for co-washing. Here, the volume of the precision washing sample container 158 is also larger than that of the main sample container 154 so that all the sample water accumulated in the main sample container 154 is sent to the washing sample container 156. Therefore, it is considered that the sample water in the main sample container 154 is reliably pumped to the subsequent stage to introduce the sample water. After a while, an air pocket is formed by compressed air on the upper side of the precision washing sample container 158, and the lower precision washing sample container 158, the second intermediate channel 157, the washing sample container 156, The one intermediate flow path 155, the main sample container 154, and the introduction flow path 153 are stable in a state where the sample water is filled.

  Subsequently, when the operator operates the operation unit 300 ′ so as to open the derivation sampling valve 164, the operation unit 300 ′ controls to open the derivation sampling valve 164. Then, seawater is further introduced from the introduction port 152 by water pressure, and the introduction channel 153, the main sample container 154, the first intermediate channel 155, the sample container for washing 156, the second intermediate channel 157, the sample for precision washing. Seawater flows into the container 158 and the entire inside of the outlet channel 159, and compressed air is discharged from the outlet 160. As a result, the introduction channel 153 and the main sample container 154 have seawater on the entire surface, water remaining after flowing, and water contaminated by the washing together are completely discharged from the main sample container 154 to further enhance the washing effect. To get the same effect. After a while, in the outlet channel 159, the precision washing sample container 158, the second intermediate channel 157, the washing sample container 156, the first intermediate channel 155, the main sample container 154, and the introduction channel 153, Stable in a state filled with sample water.

Then, when the operator operates the operation unit 300 ′ so as to close at least the introduction water collection valve 161 and the first intermediate water collection valve 162, the operation unit 300 ′ includes at least the introduction water collection valve 161 and the first intermediate water collection valve. The valve 162 is controlled to be closed. In this case, at least the introduction water collection valve 161 and the first intermediate water collection valve 162 are closed simultaneously, or at least one of the introduction water collection valve 161 or the first intermediate water collection valve 162 is closed. The control may be such that the other is closed after a while. As a result, the sample water is confined in the main sample container 154 and collected.
Thereafter, the winch 600 is operated to pull up the water sampling unit 100 ′ and the water sampling is completed.

The water sampler 1 ′ of the present embodiment has been described above. When the previous operation unit is a computer or the like, a series of operations may be automatically performed continuously with an appropriate period in between.
In such a water sampler 1 ′, the washing effect is increased by increasing the number of times of co-washing as compared with the water sampler 1 of the previous form, so that a higher quality sample water can be reliably obtained. Thus, a highly accurate inspection is possible.

  In such a water sampler 1 ′, the effect of the co-washing can be increased by increasing the number of intermediate water collection valves and the precision co-washing sample containers after the sample container 158 for the precision co-washing. The number of these intermediate water sampling valves and precision co-washed sample containers can be appropriately set according to the actual situation.

  Furthermore, there are items that can be detected only by the sensor even without the sample water. In this case, if the water quality detection sensor is settled together with the water sampling unit, data can be obtained for more water quality items. In this way, the sensor may be used in combination.

  In the previous embodiment, since the rope 400 and the signal line 200 (or the signal line 200 ') are configured to run side by side, it is particularly necessary to consider that the two lines are not entangled. Therefore, a configuration is conceivable that prevents the situation where the rope 400 and the signal line 200 (200 ') are entangled together. Such a configuration will be described with reference to the drawings. FIG. 6 is an explanatory view for explaining another example of use of the water sampler, and FIG. 7 is a cross-sectional view of an exterior cable.

  In this embodiment, when the water sampler 1 (or the water sampler 1 ') is used, the exterior cable 400' that houses the signal line 200 (or the signal line 200 ') inside is used. The exterior cable 400 ′ includes an exterior wire 401, an interior wire 402, and a cylinder portion 403. The signal line 200 (or the signal line 200 ′) is accommodated in the cylinder portion 403 and shielded from the outside, and further, the outside of the cylinder portion 403. In this case, the inner wire 402 and the outer wire 401 are twisted and reinforced to have both the strength of the wire and the function as a signal line.

  Then, the signal line 200 (or the signal line 200 ′) is drawn from the exterior cable 400 ′ near the weight 500 and connected to the water collection unit 100 (or the water collection unit 100 ′), and the exterior cable on the winch 600 side. It is pulled out from 400 ′ and connected to the operation unit 300 (or operation unit 300 ′).

If constituted in this way, the drum for signal lines 200 and 200 'becomes unnecessary, and furthermore, there is no possibility of entanglement with two lines, the feeding and winding of the outer cable 400' become easy, and water sampling There is an advantage that the work becomes easy.
