Plant Cultivation System

The present invention relates to a plant cultivation system capable of cultivating various plants using groundwater and a greenhouse.

In order to grow strawberries, which are typical low-temperature fruits and vegetables, it is most important to always maintain a temperature suitable for growth. However, the need to maintain a cool temperature all year round significantly lowers the economic feasibility due to high heating and cooling costs and maintenance costs.

In the present invention having such a configuration, it is effective to apply the principle of a siphon for smooth circulation of groundwater (GW) required for heating and cooling. To this end, first, the air in the underground water circulation unit 300 pipe must be removed and filled with water.

The first air outlet pipe 324 provided in the first groundwater transfer pipe 320, which is the upper side of the groundwater inlet pipe 310, is opened, and external water is injected through the first water inlet pipe 322 to the groundwater inlet pipe ( 310) can be filled. At this time, the first valve 312 provided in the groundwater inlet pipe 310 may be left in a closed state in advance. When the first valve 312 is provided as a check valve, when water is filled in the groundwater inlet pipe 310, it is possible to prevent water from being discharged to the groundwater GW, and when the first valve 312 is provided as a solenoid valve can remain closed.

When the first valve 312 is closed and water is supplied into the groundwater inlet pipe 310 to fill it, the air contained in the groundwater inlet pipe 310 is pushed to the supplied water and the first air outlet pipe 324 is opened. can be discharged to the outside.

Since the groundwater inlet pipe 310 is connected in communication with the first groundwater transfer pipe 320 , the water filled in the groundwater inlet pipe 310 may also be filled in the first groundwater transfer pipe 320 .

At the same time, the second valve 362 provided in the groundwater discharge pipe 360 is maintained in a closed state in the case of an electromagnetic valve, the second air discharge pipe 364 is opened, and the second valve 362 is separately provided through the second water injection pipe 352. It can be filled by injecting water from the outside. As water is filled into the groundwater discharge pipe 360 , the air in the groundwater discharge pipe 360 may be pushed and discharged to the outside through the open second air discharge pipe 354 .

The water injection pipe may be installed at a predetermined position in the groundwater passage pipe 340 located on the uppermost part of the pipe of the groundwater circulation unit 300 to inject separately provided water, if necessary. In this case, the air discharge pipe may be provided at a position where the water injected through the water injection pipe does not overflow.

The third air discharge pipe 334 provided on the heat exchange pipe 330 may also be opened to discharge the air in the heat exchange pipe 330 to the outside while being filled with water. In this way, the inside of the underground water passage pipe 340 can also be filled with water by removing air. The part from which the air does not escape may be forcibly removed by operating the pump 332 for discharging the air.

Therefore, it is possible to remove air from the inside of the underground water circulation unit 300 pipe and to keep it filled with water. The first air outlet pipe 324 , the second air outlet pipe 354 , the third air outlet pipe 334 , the first water inlet pipe 322 , and the second water inlet pipe 352 are all closed in a state in which all air is removed. can do.

After this, when the water circulation pump 326 is operated and the second valve 362 of the groundwater discharge pipe 360 is opened, the water is introduced into the groundwater inlet pipe 310 by the power of the water circulation pump 326 . Groundwater flows into and circulates into the water storage unit 110 of the cultivation area 100 through the first groundwater transfer pipe 320, the heat exchange pipe 330, and the groundwater passage pipe 340, and then comes out again through the groundwater discharge pipe 360. may be discharged underground.

When the first valve 312 of the groundwater inlet pipe 310 is a check valve, the check valve is opened in the direction from the groundwater inlet pipe 310 to the first groundwater transfer pipe 320, so that the groundwater GW is connected to the groundwater inlet pipe ( 310), passes through the inside of the water storage unit 110 through the first underground water transfer pipe 320, the heat exchange pipe 330, and the groundwater passage pipe 340, and then goes through the groundwater discharge pipe 360 again. (GW) can be returned.

The groundwater inlet pipe 310 and the groundwater discharge pipe 360 may each pass through a passage for digging underground and inserting it into the groundwater, and the atmospheric pressure acting on the groundwater inlet pipe 310 is applied to the groundwater discharge pipe 360 inserted in the passage. It is disposed in the groundwater of the same water level that acts the same as the atmospheric pressure, and there is no need to pull up the groundwater because it is previously filled with separate water. groundwater (GW) circulation can be realized.

In other words, when the atmospheric pressure acting on the groundwater inlet pipe 310 and the atmospheric pressure acting on the groundwater discharge pipe 360 are kept the same, the vapor pressure and resistance that may occur inside each pipe constituting the groundwater circulation unit 300 are higher than If the power of the water circulation pump 3260 for circulating the groundwater is large, the plant cultivation system can be operated with minimal electrical energy because the groundwater can be easily circulated through the pipe.

According to the present invention, since all incoming groundwater is recovered to the same point, there is no outflow of groundwater, which is an important resource, and problems such as stoppage of the plant cultivation system due to depletion of groundwater, subsidence of the ground, or dryness of rivers may not occur.

Therefore, the present invention can obtain significantly improved energy efficiency and reduction of installation and maintenance costs compared to a plant cultivation system using general geothermal or groundwater, and can safely and semi-permanently cultivate plants using geothermal heat without damaging the environment. have.

The power of the water circulation pump that circulates groundwater is greater than the vapor pressure and resistance generated inside the groundwater circulation unit, so that when the water circulation pump is operated, the groundwater moves and circulates from the groundwater inlet pipe to the groundwater discharge pipe Cultivation of plants system.
