Description

Apparatus for collecting sea water sample

The present invention relates to a sampling device for suctioning the seawater trapped in the seawater tank by time slots using a syringe-type seawater injector while the bottom portion of the seawater tank is pressed into the sea floor. In addition, it is possible to further improve the quality of the sample, and to determine more clearly whether or not the sampling operation of the seawater sample is performed correctly under the closed condition. It belongs to the technical field that can give greater reliability to the improvement business field.

Studies on the seabed ecology in coastal waters, which generally consist of tidal flats or sandy beaches, have been carried out on the surface of marine life (Epiauna) that adheres to or crawls on the seabed or infauna that inhabits tidal flats or sandy beaches. This is done through analysis of various gas components or chemical components generated by ecological activities, and various kinds of microorganisms growing in sea water adjacent to the sea bottom.

In addition, the contamination status of the seabed by various foreign substances or wastes from the land, and the activity of the animate and endogenous organisms caused by this, will also be judged as the result of analyzing the seawater adjacent to the seabed as a sample. Preferably, the seawater tank having a bottom portion is press-fitted through the sea bottom by a predetermined depth, and the seawater trapped in the seawater tank is collected for each time and used as a sample.

As described above, various types of sampling devices are used to collect seawater existing in the area adjacent to the sea bottom in the coastal sea as a sample. For example, one representative device may be in close contact with the sea bottom in an open state. And a seawater tank, a sampler for collecting seawater as a sample from the seawater tank, and a control mechanism incorporating a battery and a controller for operation of the sampler.

The sampler used in the sampling device is a sampling motor inserted into the motor casing and connected to the control mechanism, and a plurality of sample injectors installed along the sampler body provided outside the motor casing. Each of the sea water injector is to be in the form of a syringe in which the piston is inserted into the cylinder, the piston of the sea water injector is installed to be supported in a state in which the elasticity in the upward direction by the compressed coil spring.

Therefore, when the piston of the seawater injector rises along the cylinder according to the operation of the sampling motor, the seawater stored in the seawater tank is sucked into the cylinder of the seawater injector to store a certain amount of seawater as a sample. By allowing the sampling operation to proceed sequentially for each time zone input to the controller, the seawater samples stored for each seawater injector can provide data of ecological changes over time.

The most important factor in the collection of seawater samples using the sampling device as described above is to ensure the correct operation of each seawater injector so that the seawater is correctly inhaled at each time interval, and the seawater tank except the suction operation of seawater by the seawater injector.

A seawater tank (2), a sampler (3) for sampling seawater stored in a state trapped inside the seawater tank (2) as a sample, and a battery (45) and a controller (46) for the operation of the sampler (3). It will include a control mechanism 4 built in the outer casing (41).

In the drawing, the sampler 3 and the control mechanism 4 are positioned on the left and right sides of the seawater tank 2 and installed on the lower frame 13 together with the pedestals 31a and 41a. The position of the seawater tank 2, the sampler 3, and the control mechanism 4 is arbitrarily changed under the condition that the seawater tank 2 is press-fitted through the sea bottom so that a certain amount of seawater stays therein.

It will be included as a component.

The motor casing 31 is most preferably manufactured by using a transparent plastic material in a sealed cylinder in which seawater cannot penetrate, but the material or shape of the motor casing 31 may be changed and applied, and the sampling motor 34 In addition, it is most preferable to use a small DC motor having a reducer 35 and a cable connector 36, but any type of motor that can be controlled by the control mechanism 4 and has excellent applicability to seawater It may be used.

In addition, although the sampling motor 34 and the reducer 35 may be separately assembled and installed, it is preferable to use a geared motor in which the reducer is integrally mounted on the motor itself as the sampling motor 34. As the connector 36 is connected to the control mechanism 4 by the motor cable 47, the power supplied to the battery 45 is transferred to the sampling motor 34, while the environment set in the controller 46 is provided. In accordance with the operation of the sampling motor 34 is made to be controlled.

A pedestal 31a for assembling the sampler 3 is installed on the lower frame 13 of the apparatus frame 1 at the lower side of the motor casing 31. As a result of applying the pedestal 31a, the syringe The lower inlet 61a of the piston 61 for the seawater injector 6 having a shape may be spaced apart from the lower frame 13 at regular intervals, and thus, the cylinder 61 for each seawater injector 6. By the inlet tube (7) it is possible to ensure the convenience of the operation and the safety of the tube connecting portion and the seawater tank (2).

In addition, a driving lever 32 connected to the reduction gear 35 of the sampling motor 34 is installed at the center of the upper side of the motor casing 31 by the lever shaft 32a. The piston 62 for the seawater injector 6 is raised by pushing the switching lever 65 for the seawater injector 6 while rotating around the lever shaft 32a, which causes the seawater injector 6 to rise. Sampling operation is performed in which seawater is collected into the cylinder 61.

As described above, the seawater injector 6 used to collect the seawater sample has a syringe form consisting of the cylinder 61 and the piston 62, and the seawater injector 6 is the motor casing 31. In the outer periphery of the sample along the sampler body 33 is installed and connected to the motor casing 31 is to be installed in the vertical direction at regular intervals.

As the sampler body 33 is more clearly illustrated in FIGS. 4 and 5, the cylinder support ring 39 is positioned between the upper and lower support rings 37 and 38. Each support ring 37, 38, 39 is formed of a three-stage ring frame connected to the guide post 33b in the vertical direction, and the cylinder 61 of the seawater injector 6 is formed. Is installed between the lower support ring 38 and the cylinder support ring (39).

At the outer circumferential portions of the lower support ring 38 and the cylinder support ring 39, insertion grooves 38a and 39a are formed to allow the lower end and the upper end of the cylinder 61 to be inserted, while the cylinder support ring 39 The two ring frames are installed in close contact with the upper edge portion of the cylinder 61 for the seawater injector 6, and the piston 62 for the seawater injector 6 is inserted into the cylinder 61. Is exposed through the top of the cylinder support ring (39).

A piston clamper 63 moving vertically along the guide post 33b is connected to the piston 62 exposed through the upper portion of the cylinder support ring 39 as described above, and the piston clamper 63 is also a piston. Two clamping metal plates are assembled to be in close contact with the upper edge portion of the 62 by the clamper pin 63a, and a guide post 33b is provided between the cylinder support ring 39 and the piston clamper 63. The coil spring 66 inserted along the insert is installed in a compressed state.

In addition, a clamper rod 64 is fixedly installed in a vertical direction on the upper side of the piston clamper 63 so that the coil spring 66 can be set in a compressed state, and the clamper rod 64 Extends through the upper support ring 37, while the upper surface of the upper support ring 37 has a switching lever 65 supporting the restoring force of the coil spring 66 while pressing the clamper rod 64 downward. Each seawater injector 6 is installed.

The switching lever 65 is located within the rotation radius of the drive lever 32 rotated by the sampling motor 34, as well as connected to the upper support ring 37 by a lever shaft (65a) installed in the center thereof. As the driving lever 32 rotates, each of the switching levers 65 is rotated about the lever shaft 65a by the front end of the driving lever 32.

Due to this, in the initial setting state in which the piston 62 is fully inserted into the cylinder 61, as shown in FIG. 6A, the switching lever 65 moves to the lever according to the rotation of the drive lever 32. FIG. When pushed in the direction of the arrow (left direction) on the drawing about the axis 65a, the pressed state of the clamper rod 64 by the switching lever 65 is released as shown in FIG.

When the state as described above, as shown in (b) of Figure 6, the coil spring 66 that was inserted in the compressed state between the initial cylinder support ring 39 and the piston clamper 63 is restored ( The piston clamper 63 pushes the piston clamper 63 upward along the guide post 33b, thereby causing the piston 62 engaged with the piston clamper 63 to move upward in the cylinder 61. .

When the piston 62 is moved upward in the cylinder 61 as described above, the suction force is generated in the internal space of the piston 61 by the piston head 62a to be rubber-packed, and thus seawater The seawater trapped in the tank 2 is sucked into the cylinder 61 along the inflow tube 7 and stored as seawater samples. The sampling operation is sequentially performed for each time zone input to the controller 46, respectively. The seawater injector 6 of the seawater sample can be stored for each time zone.

As described above, the operation of the piston 62 of the seawater injector 6 for collecting the seawater sample is based on the guide clamp 33b of the sampler body 33, the clamper rod 63, the clamper rod 64, and the coil spring. Since it can be performed more securely and reliably by the (66) and the conversion lever 65, it is possible to accurately collect the seawater samples for each time period using the sampling device 10 without error, thereby Contribute to aspects of improving sample value.

In order to more safely and reliably perform the operation of the piston 62 of the seawater injector 6 as described above, two seawater injectors 6 are provided on both sides of the seawater injector 6 as shown in FIG. After the guide posts 33b are positioned, each guide post 33b is installed to pass through the piston clamper 63 so that the piston clampers 63 can be lifted along the two guide posts 33b. It is preferable.

In addition, a spherical push pin 65b is provided on the lower side of the tip of the switching lever 65, that is, the clamper rod 64 is pushed downward, whereby the switching lever 65 and the clamper rod 64 are provided. ) To minimize the friction with the drive lever 32 so that the rotation of the switching lever 65 by the drive lever 32 can be more easily achieved, as well as directly below the clamper rod 64 as shown in FIGS. 4 and 5. It is preferable that the reinforcing lower post 33a is installed between the lower support ring 38 and the cylinder support ring 39 at a position corresponding to the lower post 33a.

As a component corresponding to the second main part of the sampling apparatus 10 for collecting seawater samples according to the present invention, as shown in FIGS. 4 and 5, a part of the seawater injector 6 (preferably one) To three seawater injectors 6 include a reagent ejector 6a for injecting a liquid reagent, which is a basic material for sample measurement, into the seawater tank 2. It was made possible.

The piston 62 for the reagent ejector 6a is connected to the piston clamper 63 in a state where the liquid reagent is stored in a predetermined amount in the cylinder 61 in advance in the cylinder 61 by a predetermined length. The clamper rod 64 of the piston clamper 63 for the reagent ejector 6a is installed to be caught by the switching lever 65 in a state of protruding upward by a predetermined length through the upper support ring 37.

To this end, as illustrated in FIG. 4, a locking groove 64a is formed in the clamper rod 64, while a locking pin 65c is provided at the front end (right end in the drawing) of the switching lever 65. ) Is formed to protrude, and the coil spring 66 for the reagent ejector 6a is inserted into the compressed state along the guide post 33b between the piston clamper 63 and the upper support ring 37.

Therefore, as shown in FIG. 7A, the initial setting of the piston 62 exiting to the outside of the cylinder 61 while the liquid reagent is stored inside the cylinder 61 for the reagent ejector 6a. In the state, when the switching lever 65 is pushed in the direction of the arrow (left direction) on the drawing about the lever shaft 65a in accordance with the rotation of the drive lever 32, as shown in (b) of FIG. The locking state of the clamper rod 64 by the switching lever 65 is released.

When the state as described above, as shown in (b) of Figure 7, the coil spring 66 that was inserted in the compressed state between the first upper support ring 37 and the piston clamper 63 is restored ( The piston clamper 63 pushes the piston clamper 63 downward, thereby causing the piston 62 engaged with the piston clamper 63 to move downward in the cylinder 61.

When the piston 62 moves downward in the cylinder 61 as described above, the piston head 62a as a rubber packing formed at the lower end of the piston 62 pushes the reagent of the liquid stored in the cylinder 61. Due to this, the liquid reagent stored in the cylinder 61 is injected into the seawater tank 2 along the discharge tube 7a, and the reagent affects the data to be measured based on the seawater sample. Any kind of liquid may be used as long as it is a liquid having excellent spreading property in seawater.

As described above, the liquid reagent injected into the seawater tank 2 is present in the seawater tank 2 in a state of being mixed with the seawater, and therefore, the reagent when the seawater sample is collected by the seawater injector 6. The components are also introduced into the seawater injector 6 together with the seawater. When the amount of reagents flowing into the seawater injector 6 is measured at each time, whether the sampling of the seawater is made under the sealed condition of the seawater tank 2? It can be determined with certainty.

Prior to explaining the judgment principle according to the application of such reagents, the external seawater may be separated by the amount of seawater samples collected when the seawater sample is collected by the seawater injector 6 or when the reagent is injected by the reagent ejector 6a. It is necessary to be introduced into the tank (2), and to discharge the seawater stored in the seawater tank (2) to the outside by the amount of the reagent injected, for this purpose, the control tube 24 as shown in FIG. It is installed in the seawater tank (2).

The control tube 24 serves as a flow path between the seawater stored in the seawater tank 2 and the external seawater, and when the seawater sample by the seawater injector 6 is collected or by the reagent ejector 6a. When the reagents are injected, the internal pressure of the seawater tank 2 is prevented from increasing and lowered, and the seawater remaining in the seawater tank 2 is kept in a constant amount at all times.

The control tube 24 uses a flexible synthetic resin tube having a length of about 1m, so that the seawater except when the seawater sample is collected by the seawater injector 6 or the reagent is injected by the reagent ejector 6a. The seawater inside and outside the tank 2 is prevented from mixing with each other, and thus, the sample value of the seawater sample collected by the sampling device 10 can be further improved.

Based on the application of the control tube 24 as described above, the principle of judging the seawater sample according to the use of the reagent is described, the amount of the reagent injected into the seawater tank 2 from the reagent ejector 6a to the seawater tank ( Dividing by the volume of 2), that is, the total amount of seawater present in the seawater tank 2, the concentration of the reagents present in the seawater tank 2 is calculated, and this concentration is the seawater injector 6 Inhalation of the primary seawater sample by) results in the concentration of the reagent contained in the seawater sample.

The external seawater corresponding to the amount of seawater samples collected each time the seawater samples are sequentially collected through each seawater injector 6 for each time zone input to the controller 46 is connected to the seawater via the control tube 24. Since it flows into the tank 2, the reagent concentration inside the seawater tank 2 is lowered arithmeticly by the amount of seawater introduced from the outside with time, so that the seawater collected by each seawater injector 6 The reagent concentration of the sample will also gradually decrease over time.

If the above conditions are satisfied, it means that the sampling operation of the seawater sample is normally performed under the sealed condition of the seawater tank 2, and the reagent concentration of the seawater sample collected by the seawater injector 6 is sharply lowered at some point. In this case, as the sampling device 10 of the present invention installed on the bottom of the sea is oscillated or conducted by waves or tides or the like, or the seawater tank 2 is opened due to various factors, the external seawater has a large amount. It means that it was introduced.

In the latter case, since the seawater sample was not collected under the sealed condition of the seawater tank 2, it means that the sample could not be used as the basic data of the study, and the application of the reagent ejector 6a. As a result, it is possible to more clearly determine whether the sampling operation of seawater samples has been carried out correctly, and thus, it is possible to give greater credibility to the research results through the samples and the environmental improvement business field using the research results. Will be.

Since the reagent must be injected into the seawater tank 2 before the seawater sample collection operation by the seawater injector 6 is performed, the reagent ejector 6a is positioned at the initial point of operation of the driving lever 32. Although one reagent ejector 6a is shown in the figure, the number of reagent ejectors 6a may be installed two or three consecutively in accordance with the capacity of the seawater tank 2.

In contrast, two or three reagent ejectors 6a along the sampler body 33 are installed at regular intervals between the seawater injectors 6, thereby injecting the reagents through the seawater tank 2. In this case, the concentration of reagents in the seawater sample collected by the seawater injector 6 should be performed based on the time of injection of the reagent by the reagent ejector 6a. do.

As a component corresponding to the third essential part of the present invention, an agitator 5 for uniformly mixing the reagent injected into the seawater tank 2 by the reagent ejector 6a together with the seawater stored in the seawater tank 2 ) Is installed, the stirrer (5) and the stirring motor (53) is inserted into the motor casing (51) assembled in the upper portion of the seawater tank (2) as shown in Figs. The inner side of the seawater tank 2 includes a stirring blade 55 which is rotated by receiving the power of the stirring motor 53.

The technical details of the motor casing 51 and the stirring motor 53 for the stirrer 5 are the same as those mentioned in the description of the sampling motor 34 and the motor casing 31 of the sampler 3. As the stirring motor 53 is also connected to the control mechanism 4 by the cable connector 52 and the motor cable 47, the stirring motor 53 is operated as a power source charged in the battery 45. The operation of the stirring motor 53 is controlled in accordance with the environment set in the controller 46.

The motor casing 51 for the stirrer 5 is fixed to the upper assembly plate 25 which is a cover of the seawater tank 2, while the stirring blade 55 is the reducer 54 of the stirring motor 53. It is connected with the hub (Hub) 57 of the rotating shaft 56 extending through the motor casing 51 and the upper assembly plate 25 to the inside of the seawater tank (2).

In the drawing, the stirring blade 55 has a circular rod shape, and a total of four bars are installed on the hub 57 at an angle of 90 degrees. Thus, a rod without a conventional propeller is installed as a stirring blade. The reason why the stirring blade 55 of the shape is provided is that the reagent injected into the seawater tank 2 is uniformly mixed with the seawater, but the surface layer of the sea bottom is not separated from the rotational force of the stirring wing 55, If it can satisfy these conditions, it is a matter of course that the stirring blades of various shapes other than the rod-shaped stirring blade 55 can be applied.

When the stirrer 5 is installed on the seawater tank 2 as described above, the reagent injected into the seawater tank 2 can be mixed with the seawater more uniformly within a faster time, and thus the reagent ejector While the efficiency of the application of (6a) can be improved, the determination of the seawater sample based on the concentration of the reagent can be performed more accurately.

As the components corresponding to the fourth essential part of the present invention, as shown in FIGS. 8 and 9, DO (Dissolved Oxygen) sensors for measuring dissolved oxygen in seawater stored in the seawater tank 2 ( 23) (23a) is to be installed through the upper assembly plate 25 of the seawater tank (2) to be inserted into the seawater tank (2), the DO sensor (23) (23a) also the sensor cable (48) By the control mechanism 4 is installed.

When the DO sensors 23 and 23a are installed in the seawater tank 2 as described above, the dissolved oxygen data of each time zone can be additionally secured at the same time as the seawater sample is collected, as well as the DO sensor 23. By being able to collect seawater samples by the sampler 3 according to the dissolved oxygen amount measured by (23a), more diverse and detailed data can be obtained by using seawater samples as samples. Ecology and pollution can also greatly improve the accuracy of research.

Most preferably, there are two methods for measuring dissolved oxygen in different measuring methods, such as potentiometry, coulometry or amperometric or volt-ammetry. DO sensor 23 (23a) is divided into the corner portion of the sea water tank (2) and installed, each of the DO sensor 23 (23a) is an elastic material (rubber, etc.) installed by fitting the upper assembly plate 25 It is to be inserted into the seawater tank 2 through the sensor block 22 of the).

The reason for installing the two DO sensors 23 and 23a in the seawater tank 2 for measuring the dissolved oxygen amount by different measurement methods as described above is to secure the data on the dissolved oxygen amount in more diverse and detailed manner. Of course, when one DO sensor causes a failure or malfunction, it is because the dissolved oxygen can be measured normally using the other sensor, and the sensor block 22 is applied to the DO sensors 23 and 23a. Loss of shock absorbs the shock and protects the sensor.

In addition, at the upper end side of the seawater tank 2, an assembly flange 26 is formed to be connected to the lower frame 13 for the device frame 1 together with the upper assembly plate 25 by the assembly bolt 27. At each corner of the upper assembly plate 25, the cylinder 61 of each seawater injector 6 and reagent ejector 6a, together with the above-mentioned DO sensors 23, 23a and control tubes 24, are provided. It is provided with a tube connector 21 to which the inlet tube 7 extending from the inlet 61a and the outlet tube 7a are connected.

The tube connector 21 allows the inlet tube 7 and the outlet tube 7a to be connected to the seawater tank 2, and is injected from the reagent ejector 6a to the seawater tank 2 via the discharge tube 7a. It is responsible for the function of providing a passage for the passage of the reagent and the seawater stored in the seawater tank (2) to the seawater injector (6) through the inlet tube (7).

In addition, as shown in FIGS. 2 and 3, respectively, the upper surface of the outer casing 41 of the control mechanism 4 includes a sampling motor 34 of the sampler 3 and a stirring motor of the stirrer 5. 53) and the motor connector 44 and the sensor connector for connecting the respective DO sensors 23 and 23a to the battery 45 and the controller 46 using the motor cable 47 and the sensor cable 48. 43 is formed to protrude, while the main connector 42 to which the main cable is connected is formed to input control conditions through the controller 46 and to extract data stored in the controller 46.

If the sampling process of the seawater using the sampling device 10 of the present invention having the configuration as described above briefly described as follows.

First, all conditions for the collection of seawater samples through the controller 46 of the sampling device 10 according to the present invention, that is, the start and end time of sampling, the sampling time of seawater samples through each seawater injector 6. After setting and the like, the sampling device 10 of the present invention is loaded on a ship and moved to the coastal area where seawater samples are to be collected, and then the sampling device (using a crane or a lifting machine or a hoist) installed on the ship 10) will sink to the bottom.

As described above, when the sampling apparatus 10 of the present invention is sunk to the sea bottom, air does not stay inside the seawater tank 2, and as shown in FIG. 3, the lower end of the apparatus frame 1. The penetration bottom 15 formed at the side and the open bottom side of the seawater tank 2 are press-fitted to a predetermined depth through the sea bottom, and in this process, the sinking prevention plate 14 of the device frame 1 is connected to the sea bottom. It will be in close contact.

When the work for seating the sampling device 10 on the bottom of the sea is completed in the same manner as described above, the sampling operation of the seawater sample by the sampling device 10 is performed. Can be divided into cases.

First, the vessel stays in the position where the sampling device 10 is seated, and controls the operation of the sampling device 10 in the ship by using the main cable connected to the control mechanism 4 of the sampling device 10. This is limited to the case where the required amount of seawater sample is small and the sampling time is relatively short.

Secondly, the vessel does not continuously stay in the position where the sampling device 10 is seated, and only the seating point of the sampling device 10 is displayed by connecting a buoy and the like on a lifting rope not shown connected to the sampling device 10. In this state, the sampling device 10 automatically performs the sampling operation of the seawater sample by the battery 45 and the controller 46 provided in the sampling device 10. It can be seen that it is commonly applied to the sampling operation of seawater samples using the sampling device 10 of the invention.

As described above, the sampling device 10 of the present invention is mounted on the sea bottom and the seawater sample is collected by injecting the reagent into the seawater tank 2 using the reagent ejector 6a. ) And mixing the seawater with the reagent, and collecting the seawater stored in the seawater tank (2) as a sample using the seawater injector (6).

As described above with reference to FIGS. 6 and 7, each of the above steps is performed when the sampling motor 34 rotates the driving lever 32 in accordance with the time input to the controller 46. The drive lever 32 is achieved by sequentially pushing the switching lever 65 for operating the reagent ejector 6a and the piston 62 of the seawater injector 6, and each DO sensor in the course of this step. The measurement of the dissolved oxygen amount by (23) (23a) is performed in parallel.

After seawater samples are collected for each seawater injector 6 provided in the sampler 3 through the above process, the sampling device 10 installed on the sea bottom is lifted to the ship side and transported to the land, The seawater sample collected in each seawater injector 6 is extracted and used as a sample, while the dissolved oxygen data input to the controller 46 is outputted as data and used together with the seawater sample.

Finally, since the sampling device 10 according to the present invention is used in seawater, all the parts of the sampling device 10 are made of a material having excellent corrosion resistance to seawater, for example, stainless steel or corrosion-resistant zinc on its surface. It is preferable to apply a material such as plating or structural plastic or fiber-reinforced plastics in place.

In addition, casings 31, 41, and 51 in which electrical products such as the battery 45, the controller 46, or the motors 34 and 53 are embedded are placed in a watertight process so that seawater cannot be introduced. Of course, it is desirable to ensure that the portion where the electrical connection is made by each of the cables 47 and 48 is also sealed to prevent inflow of seawater, or to apply an underwater cable that can be used in seawater.
