The aquaculture pond water body cooling device can be distributed in a plurality of ponds, and the temperature required by the water body is determined according to the size and the environment temperature of the ponds. During the installation, insert the pond bottom through the fixed mounting pole, make each heat conduction shell 2 of the lower part of standpipe 3 in this device all be located the below water surface. One end of each pull rope 51 is connected with a lifting lug of the end cover 40 on the side surface of the heat preservation cylinder 39, and is vertically and upwards connected with the rotating disc 32 through a first pulley 53 and a second pulley 54 on the upper side of the heat preservation cylinder 39. The length of each pulling rope is fixed, so that the end cover 40 of the evaporation liquid container 41 positioned below can be just pulled by the pulling rope 51 to be in a closed state, and meanwhile, the solar heat collecting pipe 42 on the evaporation liquid container 41 positioned below can be just in an optimal light receiving state (sunny side). The pull string of the end cap 40 of the evaporation liquid container 41 at the other side, which is at the high position of the shady state, is in a loose state, so that the end cap 40 is opened under the action of the self gravity.
Because the requirements of various users are different, the environments are different, and the parameter setting is different when the device is actually used, for example, the temperature of the pond water is controlled below 25 ℃ by the user, and the temperature of the atmospheric environment is 35 ℃, the refrigerant R22 is filled in the vertical pipe 3 and the pressure is 1.0439MPa, so that when the temperature of the pond water reaches 25 ℃, the liquid R22 absorbs heat and evaporates into gas in the inner cavity at the lower part of the vertical pipe 3 and the inner cavities of the heat conducting shells 2, and the gas rises to the inner cavity of the condensation plate 12. Each of the evaporant containers 41 contains a lithium bromide solution and is evacuated to a vacuum degree according to the principle that the air in the container is evacuated as much as possible. The second valve 28 and the third valve 15 are opened and the first valve 9 and the fourth valve 22 are closed. Wherein, the lithium bromide solution in the evaporating liquid container 41 at the lower part (i.e. the side receiving the sunlight irradiation) is heated and concentrated from 40% concentration, the generated water vapor enters the condenser shell 8 through the second pipeline 30 and the second valve 28, the induced draft fan 27 operates, and the air flowing in the condenser pipe 29 condenses the vapor in the condenser shell 8 to become liquid water. At this time, the evaporator shell 23 is communicated with another evaporating liquid container 41 at a high point (i.e. the side facing away from the sunlight) through the third valve 15 and the third pipeline 10, the evaporating liquid container 41 at this side is at a low temperature, the concentration of the lithium bromide solution in the interior is at a high level, so that the pressure of the water vapor in the interior is very low, a negative pressure lower than the pressure in the condenser shell 8 is also generated in the evaporator shell 23 through the above-mentioned passage, the liquid condensed in the condenser shell 8 can automatically enter the spraying pipe 16 and then is sprayed onto the condensing disc 12, at this time, the liquid water at a high pressure meets a low internal ambient pressure in the evaporator shell 23 to generate a physical process of heat absorption and evaporation, so that the R22 gas in the inner cavity of the condensing disc 12 is cooled and becomes liquid and then descends. In the process, steam generated in the evaporator shell 23 is absorbed by the thicker lithium bromide solution in the evaporation liquid container 41 above through the third valve 15 and the third pipeline 10, that is, the concentration of the lithium bromide solution in the evaporation liquid container 41 below is increased, the overall mass is lightened, the concentration of the lithium bromide solution in the evaporation liquid container 41 above is reduced, the mass is increased, after the change of the upper and lower masses (i.e., the change of the gravity) reaches a set limit, the gravity can rotate the rotating disc 47, the rotating angle is smaller than 180 degrees, the positions before and after the rotation are just blocked by the upper blocking block 6 and the lower blocking block 37 (as shown in fig. 4), the evaporation liquid container 41 below which is positioned on the male side is exchanged with the evaporation liquid container 41 above which is positioned on the female side, then the first valve 9 and the fourth valve 22 are opened under the control of the control device 52, the second valve 28 and the third valve 15 are closed, the vertical rod 36 drives the rotating disc 32 to rotate when the rotating disc 47 rotates, and the process is repeated, and so on. The end caps 40 at both ends of the upper evaporation liquid container 41 are opened by their own weight due to the loose state of the draw cord 51, and at the same time, the fan 49 is operated to lower the temperature, and the end caps 40 at both ends of the lower evaporation liquid container 41 are closed by the draw cord 51 in a tensioned state. During operation, the water pump 26 within the evaporator housing 23 may pump internally generated liquid back into the shower 16.
The upper stop 6 and the lower stop 37 on the fixed support disk 46 also have the function of an electromagnet, and when the concentration of the solution in the two evaporated liquid containers 41 respectively reaches the limit (i.e. the weight of the container 41 at the high position reaches the maximum, and the weight of the container 41 at the low position reaches the minimum), the electromagnet loosens the attraction under the control of the control device 52, so that the positions of the two evaporated liquid containers 41 are exchanged depending on the action of gravity. After the positions are exchanged, the electromagnet is attracted again, so that the positions of the two containers are fixed again until the next cycle begins.
The lifting lug on the end cover 40 is opposite to the hinge 43 and has the function of an electromagnet, when the end cover 40 is lifted to a closed position by the pull rope 51, the electromagnet is attracted, the covering degree of the end cover 40 is enhanced, and the heat preservation effect of the heat preservation cylinder is improved; when a cycle is finished and the two evaporating liquid containers 41 need to be switched, the electromagnets are released and attracted under the control of the control device 52, so that the end covers 40 can be opened downwards by virtue of self gravity when the pull ropes 51 are released, ventilation is formed between the inside of the heat-insulating cylinder 39 and the outside, and the temperature of the lithium bromide solution in the containers 41 is reduced by virtue of the acceleration action of the fans 49 arranged at the two ends.
