Description

Apparatus of picking sample water for examination and washing pipe using inhalation pump}

The present invention relates to a sample water collecting device for collecting sample water in order to measure the water pollution of rivers, rivers, dams, shores, freshwater lakes, etc., in particular, the suction pump and the When the pass pipe is installed and the suction pump is driven to collect the sample water, the valve of the supply pipe is opened to allow the sample water to be transferred to the measuring station through the supply pipe, so that the water can be collected. Automatic sampling and backwashing apparatus using a suction pump that closes the valve and discharges the sample water discharged by the suction pump of one branch pipe to the water collection pipe through the other branch pipe and the bypass pipe to enable reverse washing will be.

As environmental pollution is getting worse due to industrial development, it is required to protect and manage the water quality of rivers, rivers, dams, coasts and freshwater lakes cleanly.

In response to these demands, many types of sample water collection devices are installed and operated in rivers, rivers, dams, coasts, and freshwater lakes to collect water from the measuring station and inspect the water quality.

Conventional sample water collecting devices include a water collecting device using a barge, a water collecting device using a cantilever, a water collecting device using a water intake, a water collecting device using a manhole, and a variable underwater water collecting device.

As shown in FIG. 1A, the water collecting device using the barge 1 has a disadvantage in that the barge 1 is lost when the flow rate rapidly increases in the summer when the rainfall is concentrated because the barge 1 must be floated on the river or the dam.

As shown in FIG. 1B, the water collecting device using the cantilever 2 is structurally stable because the method of collecting the sample water by installing a fixed structure on the riverside, but frequently occurs in case of rainfall and flooding due to the increase in flow rate, and the water level sensor Since the motor is driven by the detection of the need to adjust the position of the submersible pump, power supply was an essential problem.

As shown in FIG. 1C, the water intake structure by the intake port 3 is provided with a fixed intake in the river side to collect the sample water, so that suspended matter and foreign substances are introduced into the intake port, and thus the water can not be collected when the flow rate decreases. Or there was a disadvantage that can not be applied to the dam.

As shown in FIG. 1D, the water collecting device using the manhole 4 has a structure in which a manhole 4 is installed at the bottom and an underwater motor connected to the water collection pipe is installed therein to collect sample water, or a manhole 4 is installed at the bottom. There is a risk of safety accidents during construction, and above all, there was a problem that the construction is difficult to apply in a deep place, such as a river.

As shown in FIG. 2, the variable water harvesting device 5 is a structure that is installed in a river with a deep water and collects sample water, and lifts the underwater motor 5b supported by the lever 5a during rainfall. There is a safety advantage in that it can prevent the loss of the lever (5a) and the submersible motor (5b) by rotating to the land, but the structure is complicated and the length of the lever (5a) is limited, the representative sample water in the center of the river And there was a disadvantage that can not take the sample water of the depth.

In addition, the cantilever (2) water collecting device and the variable water collecting device (5) have to be installed in a river or riverside, so that there is a risk of damage due to the natural beauty and the loss of the flood during rainfall. Since the work must be carried out underwater, there was a high risk of safety accidents.

The Applicant has applied for a patent application for a water collecting device having a backwashing means capable of washing foreign substances while easily supplying a sample from a river or a river to a measuring station located at a safe height of 30M or more while solving all the problems of the conventional water collecting devices as described above. Patent Registration No. 10-0903015).

Since the effective height at which the suction pump used in the prior art pumps the sample water to the vertical height is limited to approximately 8M, the four or more suction pumps should be installed in a line at intervals of 8M in order to pump the sample water to the measuring station of 30M. As a result, the installation cost and maintenance were difficult, and when one of the suction pumps failed, it failed to collect the sample water.

In addition, the registered water collecting device has a means to remove the foreign matter accumulated in the water collection pipe due to the frequent water collection of the conventional water collection device is a cumbersome to replace the water collection pipe frequently if the water collection is impossible due to the accumulated foreign matter The problem was solved simply.

On the other hand, the most realistic conditions for safely and conveniently collecting the sample water for a long time are using a general purpose suction pump that is easy to purchase and inexpensive. Considering the fact that it is difficult to flood more than 8M vertical height from the surface, the measuring station where the suction pump is installed is installed at about 8M from the water surface even if it takes some risk.

However, in spite of being well aware of these circumstances, it is a reality that the sample water is collected by the conventional manual or mechanical method mentioned above while paying a lot of inconvenience and cost.

The reason for this is that when the sample water is taken for a long time, if the inside of the flow pipe where the sample water flows, that is, the inside of the water collection pipe, is blocked by impurities, there is no means for strongly transferring the sample water in the reverse direction and backwashing. It is not possible to collect water, so it is necessary to replace the water collection pipes, which is too frequent.

The reason for this is that a check valve is provided in the suction pump for pumping the sample water to prevent the reverse flow of the sample water. If the suction pump is not equipped with a check valve, the sample water being taken back to the river or river each time the driving of the suction pump is stopped, so to run the suction pump again, the sample is delivered until the sample water is supplied to the suction pump. Since this operation is too inconvenient to supply to the suction pump, almost all commercially available suction pumps are provided with a check valve or a corresponding means to prevent backflow of water.

Therefore, a simple backflow system is constructed in the water collecting device that collects the sample water by using the suction pump, and when the water collecting pipe is clogged with impurities, the water collecting device capable of supplying the sample water strongly in the reverse direction and backwashing the water collecting pipe It is required.

Accordingly, the present invention is to solve the problems of the conventional water collecting device as described above, the object is to install a suction pump and a bypass pipe in each branch pipe of the water supply pipe and the joint of the underwater collection pipe, to drive the suction pump When collecting the sample water, open the valve of the supply pipe so that the sample water can be transferred to the measuring station through the supply pipe so that the water can be collected.When cleaning the supply pipe and the underwater collection pipe, close the valve of the supply pipe to the suction pump of one branch pipe. It is to provide an automatic intake and backwashing device using a suction pump to enable the backwashing of the sample water discharged by the reverse direction to the water collection pipe through the other branch pipe and the bypass pipe.

The configuration of the automatic intake and backwashing device using the suction pump according to the present invention for achieving the above object,

An underwater collection pipe for collecting at least two separately configured pipes extending to a collection site and having an inlet exposed to the water to collect sample water;

A plurality of branch pipes are formed in a single flow channel connected to the measurement station so that the sample water collected from each of the underwater collection pipes is connected to the measurement station, and the branch pipes are connected to each of the underwater collection pipes, and the single channel and each minute The engine includes a supply pipe equipped with a valve for controlling the flow of sample water;

It is characterized in that it comprises a; controller to perform the backwashing through the underwater collection pipe through the cleaning of the supply pipe and the underwater collection pipe.

In another embodiment of the automatic intake and backwashing apparatus using the suction pump according to the present invention,

An underwater collection pipe for collecting at least two separately configured pipes extending to a collection site and having an inlet exposed to the water to collect sample water;

A plurality of branch pipes are formed in a single flow channel connected to the measurement station so that the sample water collected from each of the underwater collection pipes is connected to the measurement station, and the branch pipes are connected to each of the underwater collection pipes, and the single channel and each minute The engine includes a supply pipe equipped with a valve for controlling the flow of sample water;

A suction pump mounted on each branch pipe flow path of the supply pipe and pumping the sample water collected through the underwater water collection pipe to a measurement station;

A bypass pipe connected to a branch pipe at both ends of the pipe having separate flow paths so that the sample water of the supply pipe can flow back into the water collection pipe;

A vacuum pump installed on a flow path of the supply pipe to suction and remove air filled in the supply pipe at an initial stage of sample water collection and transfer the sample water to the supply pipe; And

Selectively opening and closing the valves of the supply pipe and the bypass pipe to supply the sample water to the measurement station, and closing the valve of the single flow path pipe during backwashing, and the sample water discharged from the suction pump of one branch pipe by the other branch pipe and the bypass pipe. It is characterized in that it comprises a; controller to perform the backwashing through the underwater collection pipe through the cleaning of the supply pipe and the underwater collection pipe.

Automatic water collection and backwashing apparatus using the suction pump according to the present invention configured as described above uses at least two or more underwater collection pipe, forming a branch pipe to correspond to the underwater collection pipe in the supply pipe to each branch pipe The suction pipe and the bypass pipe are installed in each branch pipe.

Therefore, in the present invention, when the sample water is normally collected, the controller automatically controls the valves mounted on the single channel pipe and the branch pipes of the supply pipe, so that the selected branch pipe can be opened to automatically collect the sample water. Of course, other branch pipes can be opened and water can be collected by the user's operation, so the branch pipe opening can be selectively determined according to the situation.

On the other hand, although the present invention uses a suction pump, the bypass pipe is provided, there is an advantage that can be strongly discharged in the reverse direction to wash the inside of the flow path. That is, when the controller closes the valve mounted on the single channel of the supply pipe and opens the valve of the branch pipe, the sample water discharged by the driving suction pump is quickly transferred to the underwater collection pipe through another open branch pipe. Therefore, foreign matter inside this branch pipe and underwater collection pipe is discharged to the outside.

Therefore, if the supply pipe is selectively driven by the suction pump mounted on each branch pipe in a state in which the single flow channel is closed, it is possible to cleanly backwash the plurality of branch pipes and the water intake pipe connected thereto.

A first and second branch pipes 12b (12b) disposed at (12c) and bordering the first and second suction pumps (13a) and (13b) for feeding the sample water and the first and second suction pumps (13a) and (13b); The first and second bypass pipes 14a and 14b connected to 12c and the valves V1, V2, V3, V4, V5 and V6 provided on the flow paths of the sample water are selectively opened and closed. It includes a controller (C) for controlling the flow of the sample water in the forward and reverse directions to enable the sample water supply and cleaning inside the flow path.

In the automatic intake and backwashing device 10 using the suction pump of the present invention, a vacuum pump 16 is further installed in the euro pipe 15 connected to the supply pipe 12 so that the vacuum pump 16 is filled in the flow path. Shorten the water collection time by removing air suction.

In order to construct the present invention, the first and second branch pipes 12b and 12c of the supply pipe 12 and the first and second underwater collection pipes 11a and 11b connected thereto must be prepared. Optionally, the water harvesting pipe and the branch pipe are not limited to two, but may be used more than three depending on the situation. This is because, for example, the sample water discharged through the first branch pipe 12b must be discharged through the second branch pipe 12c to the first and second water collection pipes 11a and 11b to clean the inside of the flow path. . In the figure, two underwater collection pipes, namely, first and second underwater collection pipes 11a and 11b, are shown.

The first and second water collection pipes 11a and 11b are located in the water while being connected to the first and second branch pipes 12b and 12c of the supply pipe 12, and the inlet thereof extends to the sample water collection point. It is exposed to water.

The first and second underwater collecting pipes 11a and 11b are embedded in the covering 11c and the waterproofing 11d so that the representative sample water can be simultaneously or partially collected at a plurality of places, and the respective outlets thereof. Is connected in communication with the first and second branch pipes 12b and 12c of the supply pipe 12. In the drawings of the present invention, the first and second underwater collecting pipes 11a and 11b are embedded in the covering 11c and the waterproofing 11d as shown in FIG. 7. According to the purpose of the present invention, the first and second underwater water pipes 11a and 11b are embedded in the cover material 11c and the waterproofing material 11d so that the first and second underwater water pipes 11a and 11b are formed in the form of a multi water pipe. The quantity can be selectively adjusted accordingly.

The first and second underwater water collecting pipes 11a and 11b may have three outlets connected to the inlets of the first and second branch pipes 12b and 12c of the supply pipe 12. It is connected to the connecting pipe (17a) of the connecting member 17 as shown.

The connecting member 17 corresponds to the first and second underwater water pipes 11a and 11b so as to be connected to the first and second underwater water pipes 11a and 11b on one side of the hollow body. ) Is protruded, and a screw thread 17b is formed at the inner circumference of the body to be fastened to the fastening member 12d of the supply pipe 12 to be described later.

In addition, the first and second water collecting pipes 11a and 11b are connected to and supported by the wire W to the buoyancy body B, and are positioned at a constant depth from the water surface regardless of the water level, and the ends thereof are in the direction of water flow. It is preferable to be formed to be flexible to maintain a horizontal state along the.

At the inlet end of the first and second water harvesting pipes 11a and 11b, a filter 11e is installed to prevent the inflow of suspended solids in the water, and the filter 11e has an elliptical shape with a central convex shape. It has a narrow streamline shape toward the side, and the plurality of filter holes (11e-1) are passed through the side to communicate with the inside.

When the filter 11e binds to the first and second water intake pipes 11a and 11b as shown in FIG. 5 and connects them together, the inner space is closed by the partition wall 11e-2 so as to connect them. The inner space is formed with an outlet 11e-3.

The filter 11e configured as described above is configured in a streamline shape that is narrower from the convex center to the rear, so that the floating water flows while sliding on the streamlined body, thereby suppressing the inflow of foreign substances to the maximum.

On the other hand, the wire (W) for supporting the end portion of the underwater collection pipe (11a) (11b) to the buoyancy body (B) is preferably configured to be rotatable so as not to catch the flowing float. To this end, as shown in FIG. 17, the wire W is rotated by the flow rate when the floating material is caught, and the advancing 11f is connected to both sides so that the floating material can escape.

The wire (W) located between the advent 11f is further equipped with a rotating body (11g) to increase the frictional resistance when the float is in contact so that the arrival is easily rotated so that the float is not caught on the wire. Therefore, even if the floating body is caught by the rotating body 11g, the wire W is lightly rotated by the rotating 11f, so that the floating body leaves the rotating body 11g or the wire W.

The rotating body 11g may be manufactured in various forms, and in the present specification, it is shown that the wire W is formed in an elliptical shape formed long in the longitudinal direction.

The first and second underwater collecting pipes 11a and 11b are provided with a plurality of floating bodies 11h on the end paths so that the filter 11e installed at the end may float in the water. The buoyancy body B connected to the first and second water collection pipes 11a and 11b by the wire W is positioned downstream from the filter 11e according to the flow direction of the water.

Underwater water collection pipes (11a) (11b) configured as described above can be taken to represent the representative sample water when the plural pieces are placed to the center of the water collection place.

On the other hand, it is preferable that the underwater collection pipe (11a) (11b) is firmly fixed to the bottom of the installation place so as not to be lost.

To this end, the underwater collection pipe (11a) (11b) is to be fixed by the block 18 placed on the bottom of the installation site. The block 18 should have a specific gravity greater than water so that the body can sink into water, preferably a concrete material. In view of the convenience of handling, the block 18 may have a rectangular shape with a weight of about 100 kg.

The block 18 has grooves 18a formed in the longitudinal direction of the bottom surface of the body as shown in FIGS. 10 and 12 so as to accommodate the water harvesting pipes 11a and 11b therein. A hole 18b penetrates the center of the body as shown.

The supply pipe 12 supplies a sample water collected in the underwater collection pipes 11a and 11b to the measurement station, and provides a flow path for backwashing the underwater collection pipes 11a and 11b.

The supply pipe 12 is the first and second branch pipes 12b and 12c in a single channel pipe 12a connected to the measurement station so that the sample water collected in each of the underwater collection pipes 11a and 11b can be supplied to the measurement station. Is formed, and the outlets of the first and second branch pipes 12b and 12c are connected to the outlets of the respective water collection pipes 11a and 11b corresponding thereto, and the single channel pipe 12a and each first The two branch pipes 12b and 12c are equipped with valves V1, V2 and V3 for controlling the flow of the sample water.

In the drawing, the branch pipes show two first and second branch pipes 12b and 12c. However, two or more branch pipes are provided as necessary, and these are selectively installed by operation of each valve V1, V2 and V3. Can open and close.

The valves V1, V2, V3, V4, V5, and V6 mounted on the supply pipe 12, the bypass pipes 14a and 14b and the europipe 15 to be described later are manual valves or controllers. Automatic valves controlled by (C), or both.

The supply pipe 12 is a vortex generating means on the counter flow path so that the sample water flowing back from the bypass pipes 14a and 14b to the water intake pipes 11a and 11b to cause vortices to remove foreign matters accumulated on the inner wall. Is formed.

The vortex generating means includes at least one vortex protrusion 19 protruding in a screw shape in the longitudinal direction of the boundary portion where the supply pipe 12 and the bypass pipes 14a and 14b meet. The vortex protrusion 19 is protruded in a screw shape on the inner wall of the flow passage, which is the same as the principle of passing through the bullets fired from the rifle along the grooves formed inside the barrel. Since the flow is reversed while rotating in a direction (tornacle form), it is discharged to the outside of the underwater water collecting pipes 11a and 11b while flowing in the vortex form even after leaving the vortex protrusion 19. In this process, the foreign matter accumulated on the inner wall of the flow path is dispersed by the vortex flow and discharged to the outside of the water collecting pipes 11a and 11b together with the sample water.

Here, the vortex protrusion 19 is preferably formed in a streamline so as to generate a strong vortex so that the sample water is not as much resistance as possible.

The supply pipe 12 configured in this way is connected to the underwater collection pipe (11a) (11b) is mainly located on the land or buried underground, since the three underwater collection pipe (11a) (11b) consists of a bundle of three The inner diameter is larger than that of the water collection pipes 11a and 11b so as to accommodate the case where the sample water flows from three at the same time.

A fastening member 12d is installed at an end of the supply pipe 12 so as to be connected to a connection member 17 connecting the first and second underwater water collection pipes 11a and 11b, and the fastening member 12d is At the outer periphery, a thread 12d-1 is formed which is engaged with the thread 17b of the connecting member 17.

The suction pump is a well-known that is mounted on the flow path of the first and second branch pipes 12b and 12c of the supply pipe 12 to pump the sample water to the measurement station, and to the first and second suction pumps 13a and 13b. It is composed. In general, the first and second suction pumps 13a and 13b have a much higher earth output than the suction force for sucking water. In view of this point, further expansion of the first and second bypass pipes 14a and 14b enables development of the backwashing device 10 of the present invention.

Another feature of the first and second suction pumps 13a and 13b is provided with a backflow preventing means, such as a check valve (not shown), which prevents the water, once introduced into the backflow, from flowing back. Therefore, in the conventional water collecting apparatus employing the suction pump, the sample water does not flow back because of the check valve, and thus the backwashing method cannot be applied.

Since the capacity of the first and second suction pumps 13a and 13b varies depending on the inner diameter of the flow path through which the sample water flows, the first and second suction pumps 13a and 13b may be selectively determined according to the size of the capacity.

The first and second bypass pipes (14a, 14b) is the first and second water intake of the supply pipe 12 without passing through the first and second suction pumps (13a, 13b) equipped with a check valve It is a separate pipe which diverts to water pipes 11a and 11b and flows back.

The first and second bypass pipes 14a and 14b include first and second suction pumps 13a and 13b and valves V1 having both ends of the pipes mounted on the first and second branch pipes 12b and 12c. It is connected to the first and second branch pipes 12b and 12c at the boundary of V2, and on the flow path, valves V4 and V5 are provided to block and open the flow path to control the sample water flow. The valves V4 and V5 include automatic valves controlled by manual valves or controllers C, or both.

Since the first and second bypass pipes 14a and 14b are shut off by the valves V4 and V5 when the sample water is collected at the measuring station, the flow path is closed, so that the sample water passes through the supply pipe 12 to the measuring station. Supplied. Further, when the sample water is flowed back to backwash the flow path, the first and second bypass pipes 14a and 14b are opened by the valves V4 and V5, and the first and second bypass pipes 14a opened. The first and second branch pipes 12b and 12c positioned between the single channel pipe 12a and the first and second bypass pipes 14a and 14b of the supply pipe 12 so that the sample water can be flowed back into the 14b. Is blocked by the valves V1, V2, and V3.

Therefore, the number of samples transferred to the measuring station through the first branch pipe 12b and the single channel pipe 12a is transferred to the second branch pipe 12c since the single channel pipe 12a is closed, and then the bypass pipe 14a. (14b) through the water intake pipe (11a) (11b) is backflowed at a high flow rate to clean the foreign matter accumulated on the inner wall of the flow path.

The first and second bypass pipes 14a and 14b preferably have an inner diameter smaller than that of the first and second branch pipes 12b and 12c so as to function as a venturi tube.

The controller (C) is an automatic valve (V1) (V2) (attached to the first and second suction pumps (13a) and (13b), the supply pipe 12 and the first and second bypass pipes (14a, 14b) ( V3) (V4) (V5), the automatic valve (V6) mounted on the euro pipe 15, a pressure gauge, a timer (not shown), and the vacuum pump 16 to be described later to selectively control them to collect and backwash This is equivalent to a known controller function. A detailed description thereof will be described later in the water harvesting process and the backwashing process.

On the other hand, the present invention is installed in the flow pipe 15 connected to the single flow channel (12a) of the supply pipe 12, the supply pipe 12 before the initial sample water collection, that is, driving the first and second suction pump (13a) 13b ) Is further equipped with a vacuum pump 16 for sucking the air filled in the) and for conveying the sample water collected in the first and second underwater collection pipes 11a and 11b to the supply pipe 12.

The vacuum pump 16 is driven only before driving the first and second suction pumps 13a and 13b. When the first and second suction pumps 13a and 13b are driven, the vacuum pump 16 stops driving immediately because the mission is completed. This is possible by the control of the controller C. For example, if the vacuum pump 16 is driven for about 2 minutes and the sample water flows into the first and second suction pumps 13a and 13b, the controller C drives the vacuum pump 16 for only 2 minutes. At the same time, the first and second suction pumps 13a and 13b are driven. As a result, the stop time after driving the vacuum pump 16 and the start time of the first and second suction pumps 13a and 13b are introduced into the first and second suction pumps 13a and 13b of the water collecting device. It is optionally determined by the time it takes.

In general, the suction pump has a gap between the packing of the piston and the cylinder, so that the water taken in the first and second water intake pipes 11a and 11b cannot be supplied to the inner cylinder. Therefore, in the initial stage of driving the suction pump, a certain amount of grease is supplied into the cylinder to block the gap between the packing of the piston and the cylinder in operation, and the driving force of the cylinder is intact. The collected sample water should be forced into the suction pump through the first and second branch pipes 12b and 12c.

Therefore, when the vacuum pump 16 is not mounted, the user picks up the first and second suction pumps 13a and 13b until the sample water flows into the first and second suction pumps 13a and 13b. It is cumbersome to use because it must be supplied continuously. In particular, when the distance from the water collection pipe (11a) (11b) outlet of the sample water is collected to a distance from the suction pump (13a) (13b), a large amount of grease is required, so the vacuum pump (16) is not used for such a water collection device. If not, there is a problem that virtually impossible to collect.

In the present invention, the sampled water is initially collected, and the air filled in the supply pipe 12 is suctioned and discharged using the vacuum pump 16, so that the water is collected in the first and second underwater collection pipes 11a and 11b as much as the discharged air. The sample water is transferred to the first and second suction pumps 13a and 13b and eventually flows into the first and second suction pumps 13a and 13b. Therefore, it is possible to simply solve the problem of using the pick-up each time the conventional suction pump is driven.

Therefore, the vacuum pump 16 and the first and second suction pumps 13a and 13b are automatically driven and stopped by the control of the controller C to automatically collect the sample water.

Next will be described in detail the process of collecting the sample water using the automatic collection and backwashing device 10 using the first and second suction pumps 13a and 13b of the present invention configured as described above.

In the present invention, one suction pump on the market can supply water up to about 8M vertical height, so that the measuring station is installed at about 8M from the water surface.

First, through the controller C, valves V1, V2, V3, V4, and V5 mounted on the flow path are operated to prepare a water flow path for collecting sample water. For example, the supply pipe 12 opens the valves V1 and V3 mounted on the first branch pipe 12b and the single channel pipe 12a, and the second branch pipe 12c and the first and second bypass pipes. 14A and 14B, the valves V2, V4 and V5 and the valves V6 mounted on the flow pipe 15 are closed, and the flow path through which the sample water is supplied is provided with the first water intake pipe 11a, The first branch pipe 12b and the single channel 12a are provided.

When the water flow channel is prepared as described above, as shown in the drawing, the connecting portions of the first and second underwater water pipes 11a and 11b and the branch pipes of the supply pipe 12 are located near the water surface. The water outlets of the first and second water collection pipes 11a and 11b in the same position are always filled with natural water pressure.

In this state, when the vacuum pump 16 is not used, the pick-up material is supplied to the first suction pump 13a or the second suction pump 13b to drive the first and second suction pumps 13a and 13b. .

When the vacuum pump 16 is used to drive the suction pumps 13a and 13b, it is not necessary to supply the pick-up material to the suction pumps 13a and 13b. That is, when the vacuum pump 16 sucks air filled in the first branch pipe 12b and discharges it to the outside, the number of samples collected in the first submersible pipe 11a is equal to the amount of discharged air. 12b) and finally flows into the first suction pump 13a, and the first suction pump 13a into which the sample water flows is immediately driven by the command of the controller C.

Therefore, when the first suction pump 13a is driven, the sample water is transferred to the measurement station through the first submersible pipe 11a, the first branch pipe 12b, and the single channel pipe 12a to be collected.

Since the sampled water is introduced through three first underwater water pipes 11a in which the inlet is dispersed in the water collecting place, the sample water can be referred to as representative sample water in comparison with the sample water collected at one conventional place.

On the other hand, when the first branch pipe 12b cannot be used due to a failure of the first suction pump 13a or the like, the sample water may be collected using the second branch pipe 12c. That is, by the controller C, the supply pipe 12 opens the valves V2 and V3 mounted on the second branch pipe 12c and the single channel pipe 12a, and opens the first branch pipe 12b and the first pipe. The flow path through which the sample water is supplied by closing the valves V1, V4, and V5 mounted on the two bypass pipes 14a and 14b and the valves V6 mounted on the flow pipe 15 is supplied to the second underwater. The sampling pipe 11b, the second branch pipe 12c, and the single channel pipe 12a can be used to collect the sample water.

In the present invention, the first and second underwater collection pipes (11a) and (11b) and the supply pipe 12 in the process of collecting the sample water in this way occurs when the impurities are accumulated in the sample water can not be collected, the internal flow path Can be washed.

More specifically, when washing the inside of the first underwater collection pipe 11a and the first branch pipe 12b, the second underwater collection pipe 11b and the second branch pipe 12c are used.

That is, when the user sets the washing mode by operating the controller C, the valve V1 of the first branch pipe 12b and the valve of the second bypass pipe 14b are controlled by the controller C. V5), the valve V3 of the single channel pipe 12a, and the valves V6 installed on the euro pipe 15 to which the vacuum pump 16 is connected are all locked and closed, and the second branch pipe 12c is closed. Of the valve V2 and the valve V4 of the first bypass pipe 14a are opened.

Accordingly, the flow path through which the sample water flows is the second branch pipe 11b connected to the second underwater collector pipe 11b, the second branch pipe 12c connected to the second underwater collector pipe 11b, and the first branch connected to the second branch pipe 12c. An engine 12b, a first bypass pipe 14a connected to the first branch pipe 12b, a first branch pipe 12b connected to the first bypass pipe 14a, and the first branch pipe It becomes the 1st underwater collection pipe 11a connected with 12b.

Therefore, the number of samples supplied through the second submersible pipe 11b and the second branch pipe 12c by the operation of the second suction pump 13b attached to the second branch pipe 12c is the first branch pipe. After passing through 12b, the gas is discharged to the outside via the first branch pipe 12b and the first underwater tube 11a again via the first bypass pipe 14a. At this time, since the second suction pump 13b discharges the sample water at a high speed, the discharged sample water is transferred at a high flow rate while the first bypass pipe 14a, the first branch pipe 12b, and the first submersible water pipe ( Backflow 11a) removes foreign matters accumulated on the flow path wall.

In the same manner, it is possible to clean the second underwater collection pipe 11b and the second branch pipe 12c.

Namely, the valve V2 of the second branch pipe 12c, the valve V4 of the first bypass pipe 14a, the valve V3 of the single channel pipe 12a, and the control of the controller C are controlled. The valves V6 installed in the euro pipe 15 to which the vacuum pump 16 is connected are all locked and closed, the valve V1 of the first branch pipe 12b and the valve V5 of the second bypass pipe 14b. ) Is opened.

Therefore, the flow path through which the sample water flows is the first submersible pipe 11a, the first branch pipe 12b connected to the first underwater pipe 11a, and the second branch connected to the first branch pipe 12b. An engine 12c, a second bypass pipe 14b connected to the second branch pipe 12c, a first branch pipe 12b connected to the second bypass pipe 14b, and the first branch pipe It becomes the 2nd underwater collection pipe 11b connected with 12b.

Therefore, the sample water supplied through the first submersible pipe 11a and the first branch pipe 12b by driving the first suction pump 13a mounted on the first branch pipe 12b is the first branch pipe 12b. After passing through 12b, the gas is discharged to the outside via the second branch pipe 12c and the second water collection pipe 11b again via the second bypass pipe 14b. At this time, since the first suction pump 13a discharges the sample water at a high speed, the discharged sample water is transferred at a high flow rate, while the second bypass pipe 14b, the second branch pipe 12c, and the second water collection pipe ( Backflow 11b) removes foreign matter accumulated on the flow path wall.

As described above, the present invention selectively opens the valves provided in the first and second bypass pipes 14a and 14b despite the use of the first and second suction pumps 13a and 13b provided with check valves. It is possible to wash the first and second water collection pipes (11a) (11b) and the first and second branch pipes (12b, 12c) by countercurrent.

However, the conventional sample water collecting device does not include bypass tubes 14a and 14b separately when using a suction pump equipped with a check valve, so that the sample water cannot be flowed back. Had to take the hassle to replace.
