Description

Technical Field

[0001] The utility model belongs to the technical field related to greenhouse temperature control, and particularly relates to a water supply container and a greenhouse temperature control system. Background Art

[0002] Greenhouse, also known as hot house, refers to a room with cold-proof, heating and light-transmitting facilities for cultivating thermophilic plants in winter. In the hot summer environment, the greenhouse usually uses evaporative cooling of wet curtains and fans to achieve cooling. Specifically, water absorbs the heat of the air in the greenhouse during the evaporation process to achieve the purpose of cooling; while in the low temperature environment of winter, the greenhouse usually uses heaters to heat water to achieve heating. Specifically, after the heater heats the water, the air that has been heat-exchanged with hot water is passed into the greenhouse to achieve the purpose of heating.

[0003] At present, the existing water supply container used to supply water to the wet curtain fan or heater is usually set as a box structure, and the water supply container is directly placed in the external environment. In this way, the water in the water supply container absorbs sunlight and its temperature rises when the water supply container is used to supply water to the wet curtain fan. In this way, when the water cools the greenhouse through the wet curtain fan, it is impossible to reduce the greenhouse temperature to a temperature suitable for plant growth. For this reason, other active refrigeration and cooling methods with higher energy consumption are required; and when the water supply container is used to supply water to the heater, the water in the water supply container has a lower water temperature due to heat exchange with the external low-temperature environment. In this way, when the water is heated by the heater, more energy is needed to heat the water temperature. In other words, when the existing water supply container is used for greenhouse temperature control, the energy consumption is high, thereby increasing the temperature control cost of the greenhouse.

[0036] like Figure 1 , Figure 2 As shown, a water supply container 100 provided in an embodiment of the present application includes a top wall 10, a bottom wall 20 arranged relative to the top wall 10, and a peripheral wall 30 for connecting the top wall 10 and the bottom wall 20, wherein the top wall 10, the bottom wall 20 and the peripheral wall 30 surround and form a water storage cavity 101; a water inlet pipe 40 and a water outlet pipe 50 are connected and communicated with the peripheral wall 30, and both the water inlet pipe 40 and the water outlet pipe 50 are communicated with the water storage cavity 101; a radiation cooling layer 11 is arranged on the outer surface of the top wall 10, and the radiation cooling layer 11 is used to reflect sunlight and radiate heat to the outside through the atmospheric window band, so as to reduce the temperature of the top wall 10; a sunlight absorption layer 21 is arranged on the outer surface of the bottom wall 20, and the sunlight absorption layer 21 is used to absorb sunlight, so as to increase the temperature of the bottom wall 20.

[0037] It can be understood that the water supply container 100 is used in the external environment. Specifically, the radiation cooling layer 11 or the solar light absorption layer 21 can be selected to receive sunlight according to the external environment, and the sunlight can be reflected and radiated to the outside through the atmospheric window band or the sunlight can be absorbed, so as to control the temperature of the water in the water supply container 100. This can reduce the energy required for the greenhouse temperature control system using the water supply container 100 for greenhouse temperature control, thereby reducing the cost of greenhouse temperature control.

[0038] It should be noted that when the water supply container 100 is used in summer, the top wall 10 of the water supply container 100 can be faced to the sunlight, and the radiation cooling layer 11 on the top wall 10 can be used to reflect the sunlight and radiate heat to the outside through the atmospheric window band, so that the temperature of the top wall 10 can be reduced to below the ambient temperature, and the temperature of the water in the water supply container 100 can be lower than the ambient temperature; and when the water supply container 100 is used in winter, the bottom wall 20 of the water supply container 100 can be faced to the sunlight, and the sunlight absorption layer 21 on the bottom wall 20 can be used to absorb sunlight, so that the temperature of the bottom wall 20 can be raised to above the ambient temperature, and the temperature of the water in the water supply container 100 can be higher than the ambient temperature.

[0039] Among them, the distance between the top wall 10 and the bottom wall 20 is set to 3cm~8cm, so that the distance setting between the top wall 10 and the bottom wall 20 is specifically realized, that is, the water supply container 100 can be specifically set to a flat structure, so that on the basis of ensuring the water capacity of the water supply container 100, the water in the water supply container 100 can also be fully cooled by the radiation cooling layer 11 or fully heated by the solar light absorption layer 21, thereby ensuring the temperature control of the water in the water supply container 100.

[0040] like Figure 1 , Figure 2 As shown, the water inlet pipe 40 and the water outlet pipe 50 are arranged on both sides of the peripheral wall 30, so that the water introduced by the water inlet pipe 40 can pass through the water storage cavity 101 and be discharged from the water outlet pipe 50. In this way, the position setting of the water inlet pipe 40 and the water outlet pipe 50 on the peripheral wall 30 is specifically implemented, so that the water supply container 100 can make full use of the radiation cooling layer 11 or the solar light absorption layer 21, thereby facilitating the water supply container 100 to control the temperature of the water therein.

[0041] The radiation cooling layer 11 includes a radiation cooling film and / or a radiation cooling coating. By utilizing the material properties of the radiation cooling film and / or the radiation cooling coating, the radiation cooling layer 11 can reflect sunlight when receiving sunlight.

[0042] The solar absorption layer 21 includes a solar absorption film and / or a solar absorption coating. By utilizing the material properties of the solar absorption film and / or the solar absorption coating, the radiation cooling layer 11 can absorb the solar light when receiving the solar light. In this way, the structural setting of the solar absorption layer 21 is specifically implemented, so that the solar absorption layer 21 can be made of local materials, which has the effect of reducing costs.

[0043] The water supply container 100 also includes a heat preservation layer 31 for wrapping the peripheral wall 30 to limit the heat exchange between the peripheral wall 30 and the external environment, so that when the water supply container 100 is in use, the heat preservation layer 31 can be used to keep the water supply container 100 warm, thereby further ensuring that the water supply container 100 can control the temperature of the water therein.

[0044] It should be noted that the above-mentioned insulation layer can be specifically prepared by extruded board or polyurethane foam, and the thickness of the insulation layer can be set to 3 cm. Of course, for those skilled in the art, the thickness of the insulation layer can also be set to 2 cm, 4 cm, or even any other data, which will not be elaborated here.

[0045] like Figure 1 , Figure 2 As shown, in one embodiment, the water supply container 100 further includes a rotating shaft 60, which is mounted on the peripheral wall 30 and is used to drive the water supply container 100 to flip 180° to control the radiation cooling layer 11 or the solar light absorption layer 21 to receive sunlight. In other words, when the water supply container 100 is used, the rotating shaft 60 can be used to control the flipping, which can facilitate the control of the flipping of the water supply container 100.

[0046] It should be noted that the rotation drive of the rotating shaft 60 can be driven by a motor and a gear box, and the water supply container 100 as a whole can be rotatably installed on the frame through the rotating shaft 60 to meet the use requirement of using the rotating shaft 60 to drive the water supply container 100 to flip 180°.

[0047] The water supply container 100 further includes a partition 70 , which is disposed in the water storage chamber 101 and connected to the top wall 10 and / or the bottom wall 20 to separate water flowing through the partition 70 , thereby preventing water from forming a dead corner in the water supply container 100 .

[0048] It should be noted that the partition 70 can be configured as a solid structure or a hollow structure, and the partition 70 can be specifically connected to the top wall 10 and / or the bottom wall 20 as a whole.

[0049] like Figure 2 As shown, there are multiple partitions 70, and the multiple partitions 70 form two groups of partition components, one group of partition components is arranged adjacent to the water inlet pipe 40, and the other group of partition components is arranged adjacent to the water outlet pipe 50, thus specifically realizing an embodiment of the partition 70 being arranged in the water supply container 100.

[0050] like Figure 3As shown, a greenhouse temperature control system provided in one embodiment of the present application includes a wet curtain fan 200, a heating device 300 and the water supply container 100 described above. The wet curtain fan 200 and the heating device 300 are connected and communicated with the water supply container 100 in parallel, and the water supply container 100 can selectively supply water to the wet curtain fan 200 or the heating device 300.

[0051] It should be noted that the wet curtain fan 200 and the heating device 300 are installed on the greenhouse 500, and the water supply container 100 can be connected with the wet curtain fan 200 and the heating device 300 by a three-way valve 400, so that when the greenhouse temperature control system is working, when it is necessary to cool down the greenhouse 500, the three-way valve 400 can be used to control the water supply container 100 to be connected with the wet curtain fan 200 through the first circulation pipeline 601, and the water supply container 100 supplies water to the wet curtain fan 200, and then the wet curtain fan 200 is used to cool down the greenhouse 500; and when it is necessary to heat up the greenhouse 500, the three-way valve 400 can be used to control the water supply container 100 to be connected with the heating device 300 through the second circulation pipeline 602, and the water supply container 100 supplies water to the heating device 300, and then the heating device 300 is used to heat up the greenhouse 500.

[0052] Among them, the heating device 300 specifically includes a heater 301 and a heat exchanger 302. The heater 301 can heat the water provided by the water supply container 100, and the heat exchanger 302 can exchange heat between the heated water and the air, and then input the heated air into the greenhouse 500 to achieve the heating operation of the greenhouse 500.

[0053] In summary, the water supply container 100 and the greenhouse temperature control system for which protection is sought in the present application are capable of selectively reflecting sunlight and radiating heat to the outside through the atmospheric window band or absorbing sunlight according to the external environment, thereby controlling the temperature of the water in the water supply container 100. This can reduce the energy consumption required for greenhouse temperature control by the greenhouse temperature control system using the water supply container 100, thereby reducing the cost of greenhouse temperature control.
