Description

  The present invention relates to an underwater ice storage device and method for a reservoir, and more specifically, the water in the reservoir for freezing the water in the reservoir by using cold air in winter and storing the ice produced for a long period until summer. The present invention relates to an ice storage device and method. In particular, cold water and cold air generated at the time of ice melting are used for cultivation and storage of crops, and at the same time, for protecting the water quality and securing the amount of water.

  A reservoir is an artificial facility that stores running water and regulates excess or deficiency of water, and is an important surface water source used when sufficient water cannot be secured from rivers. Such reservoirs vary widely, from small puddles to large dams.

  In general, when sunshine is generated in the spring when agricultural water and drinking water are required, it has a fatal effect on the cultivation of crops, and many people are forced to live inconveniently due to a lack of water for daily use. And such a phenomenon is repeated every year with only a difference in degree.

  In order to solve this, it is necessary to secure a sufficient amount of water in the reservoir, but as an example, more reservoirs must be constructed or the size of the reservoir must be further increased.

  However, it takes a lot of time and money to construct a new reservoir, and in particular, there is a problem that astronomical costs are required to construct a large reservoir. In addition, the construction of the reservoir must take into account the impact on the surrounding environment, as well as various problems, both large and small, such as compensation problems due to the construction of the new reservoir, destruction of the landscape, loss of cultural assets, etc. In spite of these problems, it is not only inefficient to build many reservoirs in a limited country, but there are not many places suitable for the construction of reservoirs. Cannot be offered.

  On the other hand, even if the number of reservoirs is increased, the amount of water stored in the reservoir continues to decrease due to the huge amount of evaporation because the amount of precipitation is small and the amount of evaporation is large every year during the dry season of winter and spring. Because of this phenomenon, the bottom of the reservoir is exposed almost every year before the rainy season, but this is a problem that cannot be solved by simply increasing the number of reservoirs or constructing a large dam.

  As a result, there is a problem that the limited reservoir cannot provide sufficient water during the drought period of early spring, and the amount of water storage that can solve the shortage of agricultural water and domestic water due to sunshine cannot be secured. In addition, problems such as contamination of water quality due to an increase in phytoplankton due to a rise in water temperature in summer occur.

Therefore, the present applicant has filed an ice storage method for a reservoir (see Patent Document 1 below) for solving the above-described problems. However, the method of storing ice in a reservoir that has already been filed has the disadvantage that it takes a lot of energy and cost in the process of drawing water and spraying it on the water surface during ice making. In addition, it is characterized only by prevention of ice evaporation and prevention of water resource contamination, and there is room for reconsideration of a method for effectively using the cold air and cold water generated during ice melting. In particular, there are demands for an improvement plan for storing iced ice for a long period of time and an improvement plan for using cold water and cold air generated at the time of ice melting.

FIG. 3 is a schematic view of an underwater ice storage device for a reservoir according to another embodiment of the present invention.

  As shown in FIG. 1, support bases 110 and 120 are installed on the bottom surface and the inclined surface of the reservoir. Of these, the bottom support table 110 is the one installed on the bottom surface, and the inclined surface support table is the one installed on the inclined surface. 120. Such support stands 110 and 120 are means for preventing ice produced in the reservoir in winter from coming into contact with the ground and melting due to geothermal heat.

  The structure of the support bases 110 and 120 will be described in detail with reference to FIG. At this time, the bottom surface support 110 and the inclined surface support 120 have the same structure, and therefore the bottom surface support 110 will be described as an example.

  The floating support 130 which connects them is installed in the inclined surface support stand 120 located so that it may mutually oppose among the support stands 110 and 120 comprised in this way. The floating rod 130 is a means for separating the ice made from the support bases 110 and 120, particularly from the bottom surface support base 110. Such a floating rod 130 forms a space between the ice and the support table 110 so that water generated at the time of defrosting is immediately separated from the ice, so that the ice made in the winter can be kept until the summer. Delay the ice-breaking time so that it can exist.

  At this time, a large number of floating ropes 140 are installed on the floating rod 130 so that heavy ice can be more easily suspended from the floating rod 130. A weight weight 142 is installed at the lower end of the floating rope 140 to prevent the floating rope 140 from rising to the water surface or being exposed to waves before ice making.

  A compressor 160 is installed on one side of the reservoir in which the support tables 110 and 120, the floating rod 130, and the floating rope 140 are installed. Such a compressor 160 maximizes the amount of dissolved oxygen in the water stored in the reservoir, and at the same time compresses the cold air below zero in winter so that ice can be made. Here, the installation position of the compressor 160 is preferably installed on the ground as in this embodiment so that maintenance is easy.

  A transfer pipe 170 through which cold air below zero (hereinafter referred to as compressed cold air) compressed by the compressor 160 is transferred is installed through the support bases 110 and 120 installed on the bottom and inclined surfaces of the reservoir. Such a transfer pipe 170 is branched into branches, and is evenly arranged on the entire bottom surface of the reservoir. A nozzle 172 is installed at the end of the transfer pipe 170 to inject compressed cold air into the water, and is stored in the reservoir. Makes water ice. When a microbubble generator (not shown) is added inside the compressor 160 or on the transfer pipe 170, the compressed cold air injected from the nozzle 172 can be made into microbubbles and injected.

At this time, if the compressed cold air is converted into microbubbles and injected through the microbubble generator, the amount of compressed cold air injected is reduced compared to direct injection, but the amount of dissolved oxygen in the water before ice making can be increased. it can. On the other hand, if it directly injects without passing through a microbubble generator, the injection quantity of compressed cold air will increase and the ice making effect can be promoted. Therefore, it is preferable to select and use it according to the environment at the time of ice making and the needs of the user.
On the other hand, a water collecting place 180 for storing cold water and cold air generated during ice melting is provided at one side of the reservoir, and the water collecting place 180 has discharge means 182 and 184 for discharging the stored cold water and cold air to the outside.

The switch 196 can withstand the water pressure of the reservoir in the early stage of ice making, and the ice is melted when the ice is thawed. The material must be able to withstand the heat transferred through the means 200.

  When such an ice-melting means 200 is used, the cold water which the ice on the pipe line 189 melt | dissolved and collected on the bottom face of a reservoir can be discharged | emitted to the water collection place 180 side. Moreover, when supplying warm air to the bottom face of the reservoir using the blower 184 or the transfer pipe 170, the ice in the reservoir can be defrosted from below. At this time, cold water generated by melting ice is discharged to the water collecting field 180, and it is possible to prevent the ice from being immersed in the cold water to increase the ice melting speed, and ice produced in winter can be sustained until summer. Moreover, although cold air is always contained inside the water collecting field 180 and the reservoir, the ice can be stored for a long time if it is discharged as little as possible.

  On the other hand, delay means 192 and 194 are provided for delaying the ice melting made in winter, one of which is a windbreak fence 192 installed along the circumference of the reservoir, and the other is It is the light shielding film 194 installed in the upper part of a reservoir.

Such support stands 110 and 120 are means for preventing ice produced in the reservoir in winter from coming into contact with the ground and melting due to geothermal heat.

  As shown in FIG. 2, the support bases 110 and 120 have a gabion structure in which a filler 114 is filled in the wire mesh 112. Here, the filler 114 is a mineral so that minerals can be supplied to water stored in the reservoir (water before being made into ice) and water that is generated when the ice is melted and flows to a water collecting field 180 described later. Is preferred.

  The floating support 130 which connects them is installed in the inclined surface support stand 120 located so that it may mutually oppose among the support stands 110 and 120 comprised in this way. The floating rod 130 is a means for separating the made ice from the support bases 110 and 120, particularly from the bottom surface support base 110. Such a floating rod 130 forms a space between the ice and the support table 110 so that the water generated at the time of defrosting does not come into contact with the ice, so that ice produced in winter exists until the summer. Delay the thawing time to get.

  At this time, the floating net 150 is installed on the floating rod 130 and a weight 152 is installed on the lower end of the floating net 150 to prevent the floating net 150 from rising to the water surface or being exposed to waves before ice making. .

  A compressor 160 is installed on one side of the reservoir in which the support tables 110 and 120, the floating rod 130, and the floating net 150 are installed. Such a compressor 160 maximizes the amount of dissolved oxygen in the water stored in the reservoir, and at the same time compresses cold air below zero in winter so that ice can be made. Here, the installation position of the compressor 160 is preferably installed on the ground as in this embodiment so that maintenance is easy.

  A transfer pipe 170 to which cold air below zero (hereinafter referred to as compressed cold air) compressed by the compressor 160 is transferred is installed in parallel with the floating rod 130, and nozzles 172 are formed along the transfer pipe 170 at regular intervals. .

  On the other hand, a water collecting place 180 for storing cold water and cold air generated during ice melting is provided at one side of the reservoir, and the water collecting place 180 has discharge means 182 and 184 for discharging the stored cold water and cold air to the outside. Is provided. As an example, the cold water is discharged to the outside by the pump 182, and the cold air is discharged to the outside by the blower 184.

  At this time, the ice-melting means 200 is installed on the pipe line 189 connecting the water collecting field 180 and the reservoir. The de-icing means 200 includes a heating pad 210 that covers the pipe 189 and a heat generator 220 that generates heat. The heat generated by the heat generator 220 is supplied to the heating pad 210 to melt the ice on the pipe 189. .

The switch 196 can withstand the water pressure of the reservoir in the early stage of ice making, and the ice is melted when the ice is thawed. The material must be able to withstand the heat transferred through the means 200.

  Further, the water collecting field 180 is connected to the outside through the ventilation port 186 and can discharge unnecessary warm air generated in the water collecting field, thereby preventing the stored cold water and the temperature of the cold air from rising.

  In addition, a damper 188 is provided on the inner upper portion of the water collecting field 180, and warm air of zero degrees Celsius or more flows through the ventilation opening 186 in the summer, or the warm air generated in the water collecting field flows back to the reservoir side To prevent.

Here, the light shielding film 194 not only blocks light but also prevents rainwater and the like from directly falling on the ice surface. At the same time, it is preferable to have a structure that can be opened and closed so that the ice can be irradiated with ultraviolet rays as necessary for sterilization of ice.

  In other embodiments of the present invention as described above, the support bases 110 and 120 may be removed or the structure of the support bases 110 and 120 may be simplified as required by the user.

  FIG. 4 is a flowchart of an underwater ice storage method for a reservoir according to an embodiment of the present invention.

  The details of the underwater ice storage method for the reservoir using the underwater ice storage device for the reservoir according to the embodiment of the present invention configured as described above with reference to FIGS. 1 and 4 are as follows.

  A step of installing the support bases 110 and 120 on the bottom surface and the inclined surface of the reservoir (S10), and a step of installing the floating rod 130 connecting the inclined surface support bases 120 positioned so as to face each other among the support bases 110 and 120. (S20), a step of compressing subzero cold air (S30), a step of transferring subzero compressed cold air (S40), a step of injecting the transferred subzero compressed cold air into water (S50), and ice making. A step of delaying the deicing of the ice (S60), a step of defrosting by supplying warm air (S70), and a step of storing and using cold water and cold air generated during the defrosting (S80). .

  Each step will be described in more detail.

  First, production of the support bases 110 and 120 for installing the support bases 110 and 120 on the bottom surface and the inclined surface of the reservoir must be preceded. As described above, the support bases 110 and 120 have a gabion structure (see FIG. 2), and include a wire mesh 112 and a filler 114 filled in the wire mesh 112.

  When the support bases 110 and 120 having such a structure are installed on the bottom surface and the inclined surface of the reservoir, ice produced in the reservoir in the winter does not directly contact the ground, so that it is possible to prevent defrosting due to geothermal heat. Further, when a mineral filler is used as the filler 114 filled in the wire mesh 112, the water stored in the reservoir (water before being made into ice) and the ice is melted and flows to the water collecting field 180. Since minerals can be supplied to water, it is more effective. Of course, in the case of another embodiment of the present invention, the support bases 110 and 120 can be removed or the structure of the support bases 110 and 120 can be simplified.

  When the manufacture of the support bases 110 and 120 is completed, the support bases 110 and 120 are installed on the bottom surface and the inclined surface of the reservoir, and the floating rod 130 that connects the inclined surface support bases 120 positioned to face each other is installed. Install.

  The floating rod 130 is a means for separating the ice made from the bottom support 110 and forming a space between the ice and the bottom support 110. That is, the ice that has been made in the winter can be maintained until the summer by delaying the ice-breaking time so that the ice is not immersed in the water generated during the ice-breaking.

  On the other hand, when a floating rope (140 in FIG. 1) or a floating net (150 in FIG. 3) is installed on the floating rod 130, the heavy ice can be fixed more easily. That is, by preventing the ice from falling by the floating rope 140 and the floating net 150 and increasing the contact area between the ice, the settling force is improved and the ice can be fixed more easily.

  Here, since the floating rope 140 or the floating net 150 is lightweight, it can rise to the water surface or be exposed to waves before the water is made into ice, but if the weights 142 and 152 are installed at the lower ends thereof, Can solve the problem.

  When the installation of the support stands 110 and 120, the floating rod 130, the floating rope 140, or the floating net 150 is completed, the cold air below zero in winter is compressed with a constant pressure using the compressor 160.

  As described above, when the cold air compressed by the compressor 160 is injected, the water stored in the reservoir is made into an ice with the amount of dissolved oxygen increased. Of course, it is not a problem because it is easy to get cold in winter when the temperature is below zero, but this is not the case in regions where there are many days of winter temperatures above zero degrees Celsius. In this case, ice can be made by installing an additional freezer.

  The cold air thus compressed is injected into the water of the reservoir through the transfer pipe 170 and the nozzle 172. At this time, when a microbubble generator (not shown) is added to the inside of the compressor 160 or on the transfer pipe 170, the dissolved oxygen amount of water can be maximized before the microbubbles are jetted to make ice, and the ice making time can be maximized. Can also be shortened.

  In addition, when the water below the ice layer 102 formed on the water surface is pulled up and discharged to the outside, the ice making time can be further shortened. This is the method of storing ice in a reservoir devised by the present applicant (the above Patent Document 1). See).

  Here, as in another embodiment of the present invention shown in FIG. 3, a transfer pipe 170 is installed in parallel to the floating rod 130, and compressed through nozzles 172 formed along the transfer pipe 170 at regular intervals. It is also possible to make ice by spraying the cooled air.

  Various ice storage devices and methods as described above can be selectively implemented according to the ambient conditions.

  On the other hand, the ice layer 102 formed on the water surface of the reservoir is formed with a vent (not shown) for discharging compressed cold air sprayed to make water. While the compressed cold air is discharged through this vent, water is also discharged due to the volume expansion effect of ice, but the water discharged through the vent is frozen by the outside air below zero and stands in volume expansion. Icicles 104 are formed.

  Standing icicle 104 is an icicle that extends upward like a stalagmite in a limestone cave, when the water temperature and temperature are frozen near the freezing point, and when the air is dry and the amount of water evaporation is large It is easy to be formed. Therefore, when a large number of standing icicles 104 are formed by preparing such an environment, it can be used for education and appreciation, and also as a tourism resource.

  After the ice is fully frozen, if the bottom of the ice melts first, or if the water remaining under the ice is removed, a gap is formed between the ice and the support stands 110 and 120, and the gap accumulates. The cooled air acts as a heat insulating agent. At this time, the drained water or the additional water can be sprayed onto the ice plate to make the ice thicker, as specified in the ice storage method for the reservoir (Korean Registered Patent No. 10-829825).

  On the other hand, when the cool air continues to be supplied even after the water in the reservoir is made, a gap is generated between the inclined surface support 120 and the ice, and this gap discharges the cool air injected through the nozzle 172 to the outside. It becomes a passage to do. Accordingly, after the water in the reservoir is made into ice, a gap is formed between the inclined surface support 120 and the ice, and then the cold air below zero can be continuously injected to further harden the ice.

  On the other hand, if the outside air temperature rises above zero degrees Celsius, unnecessary temperature rise of ice can be prevented by blocking the warm air flowing in through the transfer pipe 170 or the like. Further, in order to quickly defrost the ice, hot air may be blown through the transfer pipe 170.

  If the water in the reservoir is completely frozen, the gap is closed and the inflow of compressed air becomes difficult, so the temperature rises and some ice melts to wait for the gap to form naturally. Compressed air is drawn between the support 120 and ice so that a gap is formed between them. Such a gap can also serve as a passage for cold water generated during ice melting.

  Ice made in winter through the process described above is naturally melted in summer. At this time, in order to delay the ice melting time, a windbreak fence 192 can be installed along the periphery of the reservoir, or a light shielding film 194 can be installed on the upper portion of the reservoir. That is, a light shielding film 194 is installed to prevent contact between rainwater and solar heat, and a windbreak fence 192 is installed to prevent contact with wind and prevent accumulated cold air from flowing out.

  Thereafter, ice is made as necessary to obtain cold water and cold air, but when the pipe 189 connecting the water collecting field 180 and the reservoir freezes, the previously installed ice melting means 200 is used. Use it to defrost. That is, the heat generated in the heat generator 220 can be supplied to the heating pad 210 to melt the ice on the pipe line 189. At this time, since the switch 196 and the pipe line 189 may be opened, any material that can withstand heat may be used in preparation for heating.

  When such an ice-resolving means 200 is used, the ice on the pipe 189 melts and the cold water accumulated on the bottom surface of the reservoir can be discharged to the water collecting field 180 (at this time, the blower 184 and / or the transfer pipe 170 is connected). When using it to supply warm air to the bottom of the reservoir, the reservoir ice can be thawed from the bottom). Therefore, it is possible to prevent the ice from being immersed in the cold water and the defrosting speed to be increased, and the ice made in the winter can be sustained until the summer.

  Finally, cold water and cold air generated during ice melting are stored in a water collection place 180 provided on one side of the reservoir, and the cold water and cold air stored in the water collection place 180 are like a pump 182 and a blower 184. It is discharged outside by the discharging means 182 and 184.

  The cold water discharged in this way has a great effect in preserving the amount of water resources because it lowers the downstream water temperature and suppresses evaporation. In addition, since the growth of plankton is greatly suppressed, water pollution due to tidal currents can be prevented. In addition, the discharged cold water and cold air can be used for long-term storage of cereals, vegetables, fruits and the like, and can be used for cultivation of crops that can only be performed at low temperatures. Therefore, the energy conventionally used for cultivation and storage of crops can be dramatically reduced, and the amount of carbon dioxide generated can be reduced.

  As an example, when cold air is used to store rice, the quality of rice can be reliably preserved and the taste of new rice can be maintained for several years. Moreover, when using cold water and cold wind, high quality straw can be cultivated. It is possible to cultivate not only agricultural crops but also cold-flowing fish that can live only in water areas with an annual average water temperature of 15 to 16 ° C. or less.
