1 and 2 are views for explaining the closed ecosystem experiment apparatus 1 according to the present invention;

3 to 6 are diagrams for describing the light blocking blind 160.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. The following examples are only presented to understand the content of the present invention, and those skilled in the art will be capable of many modifications within the technical spirit of the present invention. Therefore, the scope of the present invention should not be construed as limited to these embodiments.

1 and 2 are views for explaining the closed ecological experiment apparatus 1 according to the present invention.

As shown in Figure 1 and 2, the closed ecological experiment apparatus 1 according to the present invention comprises a storage tank 10, the distribution tank 20, and the ecological tank (30). The ecological tank 30 is formed with an inlet 31 and an outlet 32. It is preferable that the aeration means 5 is connected to the reservoir 10 so as to blow air into the reservoir 10.

In the case of flowing water such as rivers, rivers, seas, etc., the flow rate will vary depending on the depth of the water, so that the inlet 31 of the ecological tank 30 may have a different height to reflect the ecological environment. It is formed of a plurality of layers. The inlet pipe 40 is provided in plural to correspond to each inlet 31, it is preferable that the flow control means 41 is installed in each of the inlet pipe (40).

When the flow rate of the water flowing into the ecological tank 30 varies by depth through the control of the flow regulating means 41, the environment in the ecological tank 30 is formed very close to the actual environment of the flowing water such as a river or a river. .

For smooth flow, the outlet 32 is preferably formed on the other side wall of the ecological tank 30 so as to face the inlet 31. The outlet port 32 is preferably provided with a discharge port 60 into the ecological tank 30, the discharge port 60 is one end 63 is facing down, the other end 62 is upward. Towards the other end 61 is located in the center is connected to the outlet 31 is preferably in the form of a "T" lying sideways as a whole. Here, the upwardly facing end 62 will serve as a vent structure through which air escapes. If there is no vent port there is no need for such a vent because there is no place to escape the air because the water may not be smoothly discharged through the discharge port (60).

The outlet 32 is also preferably formed in a plurality of layers to vary the height, and at this time, the outlet 32 does not have to be located on the same horizontal line as the inlet 31, and may be located at an offset level. It is preferable that the flow rate adjusting means 51 is provided in the outflow pipe 50 corresponding to each outlet 32 for flow control.

In order to collect the depth-specific samples of the ecological tank 30, the intake pipe 70 is preferably installed to penetrate the ecological tank 30 in a plurality of layers on the side wall on which the outlet 32 is located. Opening the intake pipe opening and closing valve (75) with the sample collected through the intake pipe (70) ecological investigation and research is made.

A plurality of outflow pipes 50 are connected to one collection outflow pipe 80 so that the water flowing out of each layer in the ecological tank 30 through the outflow pipe 50 is collected into one and discharged outside. A branch pipe 87 is installed in the collection outlet pipe 80 so that the water collected through the collection outlet pipe 80 branches and is discharged. A branch pipe opening / closing valve 81 is installed in the branch pipe 87, and a collecting discharge opening / closing valve 82 is installed in the collecting outlet pipe 80 so that the branch pipe 87 is located behind the branched part. A water bottle 85 is installed at the end of the branch pipe 87 to receive the water discharged from the branch pipe 87.

Branch pipe 87 is for use in determining the flow rate in the ecological tank (30). Closing the collection discharge opening / closing valve 82 and opening the branch pipe opening / closing valve 81, the water discharged from the ecological tank 30 will be received in the water bottle 85, and at this time, the amount of water received in the water bottle 85 per hour is measured. By checking, the flow rate in the ecological tank 30 can be grasped. The flow rate flowing in the ecological tank 30 is adjusted by adjusting the flow control valve 41 of the inlet pipe 40 or the flow control valve 51 of the outlet pipe 50 based on the flow rate in the ecological tank 30 thus identified. You can adjust it to the desired level.

When the branch pipe closing valve 81 is closed and the collection discharge opening / closing valve 82 is opened, the water in the ecological water tank 30 passes to the next step through the collecting outlet pipe 80. Here, the next step may be embodied in various ways, such as going to another ecological tank that is subsequently installed or returning to a storage tank.

On the other hand, there is a difference in darkness in addition to the flow rate difference depending on the depth. Normally, the deeper it will be, the darker it will be. Therefore, it is preferable that one or more layers of light shielding blinds 160 are installed around the side wall of the ecological water tank 30 to reflect the ecological environment. In order to be able to control the brightness (darkness) in the water by depth, a plurality of layers may be preferable.

3 to 6 are diagrams for describing the light blocking blind 160.

Referring to FIGS. 3 to 6, the light blocking blind 160 is formed by a plurality of light blocking pieces 180 arranged in parallel to each other, and each of the light blocking pieces 180 is formed on the vertical rotation axis 181. It is installed to be rotatable. When one of the light blocking pieces 180 rotates left and right, the connection line 190 of the light blocking piece 180 is opened so that the other light blocking pieces 180 on the same layer are opened or closed together accordingly. It is preferable to be installed to pass through the light shielding piece 180 on the same layer while being connected to one side portion.

The connection line 190 may be connected to the light shielding piece 180 may be various, but considering the ease of disassembly and assembly, the line ring 195 at one side of the light shielding piece 180 so that the connection line 190 is fitted. ), And the hooking means 193 is preferably installed on the connection line 190 so that the connection line 190 does not slide left and right in a state where the connection line 190 is fitted to the line ring 195.

When the light shielding piece 180 is closed, the connection line 190 will be loosened, and when it is opened, the connection line 190 will be pulled tightly. The line ring 195 may be slightly adjusted so as to reasonably correspond to the former and latter states. It is preferably made of a flexible material.

The line ring 195 preferably includes a line inserting portion 191 which is a passage into which the connecting line 190 is fitted and a line fixing portion 192 on which the connecting line 190 is seated. The hooking means 193 is preferably made so that a plurality of droplets are fitted to the connection line 190. Then, the connection line 190 can be easily pulled out and inserted from the line ring 195 through the line insertion unit 191, so that the number of drops between the line rings 195 can be counted according to the situation through this process. 190 may be fixed to the line loop 195 at uniform intervals.

Rotating shaft 181 is preferably installed so that up and down is fitted to the horizontal support 165 is installed horizontally between the layers of the light-shielding blind 180. In the figure, the case in which the ecological tank 30 is cylindrical and the horizontal support 165 is installed in a circular rim shape around the ecological tank 30 is illustrated.

The side wall of the ecological tank 30 is made of a transparent material to allow light to pass through, and the shading piece 180 is preferably made of an opaque material that can block light to provide darkness into the ecological tank 30. Do.

Where the inlet pipe 40 and the outlet pipe 50 is installed, the light shielding piece 180 may not be smoothly rotated by being caught by the inlet pipe 40 and the outlet pipe 50. 180 is fixedly installed or a through hole is provided in the light shielding piece 180 at a portion where the inlet pipe 40 and the outlet pipe 50 pass in order to provide a clearance so that rotation of the light shielding piece 180 is not disturbed. It is desirable to be formed.

Rotating shaft 181 is preferably biased to one side of the light shielding piece 180, but is spaced apart from the side end, the horizontal support 165 so that the opening degree is limited by the side portion entering inward when the light shielding piece 180 is opened. It is preferable that the light blocking piece catching jaw 167 is formed.

When the light shielding piece 180 is closed, it is preferable that the left and right sides of the light shielding piece 180 overlap each other. This overlapping portion effectively prevents light from leaking into the gap between the light blocking pieces 180. Even though the side portions of the light shielding piece 180 are closed to overlap, light is leaking in between the light shielding pieces 180 so that light may leak in between them. By installing the bar 182, it is more preferable to block the leakage of light double.

It is preferable that the light shielding piece 180 has a dark color inside so that a dark atmosphere is formed at the closed portion. It is better to vary the degree of dark color by the number of layers of the light-shielding blind 160 so that the degree of darkness varies by depth. For example, the deeper the water, the darker the water, so when the inner surface of the light-shielding blind 160 on the first floor to a darker color than the light-shielding blind 160 on the third floor, the interior of the water tank 30 is actually a natural ecological environment. Will be closer to.

Ecological water tank 30 is preferably covered with a lid 150 to open and close the upper portion, it is preferable to be separated into a plurality because the lid 150 is made of a single body so difficult to open and close. . In the drawings, a case in which two are separated is illustrated. Lid 150 is preferably in the form of a mesh to allow air and light to pass through. Of course, the light may be made of a transparent polymer material, but the inflow of foreign matter may be blocked. In the upper space of the lid 150 is preferably provided with a light irradiation apparatus 90 for irradiating light.

As described above, according to the present invention, the flow rate and the degree of darkness can be varied according to the depth of water, and the light irradiation amount can be adjusted, so that the environment inside the ecological tank can be made closer to the actual ecological environment in the water, which is very accurate. It is possible to reliably investigate or study the ecological environment in water.

In particular, in a state in which the collecting outlet pipe 80 is intact without being separated from a subsequent device connected thereto, the discharged flow rate can be determined with the water bypassed through the branch pipe 87 and the flow rate can be adjusted based on this. It is convenient.
