It is usually used to grow plants and provides an ideal growth environment for plants by artificially controlling the temperature, humidity, light, ventilation and other conditions inside.

However, there are still the following shortcomings:

[0004] The airflow of this device has a single blowing direction, and only forms a strong airflow in its straight direction.

Specific implementation manners

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] Embodiment 1

[0035] Such as Figure 1 、 Figure 2 And Figure 5As shown, the present embodiment discloses a double-storage double-arch composite heat-insulating solar greenhouse, including a base 1, the base 1 is the ground, for the convenience of explanation, it is expressed as the base 1, the upper left part of the base 1 is provided with a heat-insulating wall 7, the middle part of the left end of the heat-insulating wall 7 is provided with a fan 8, the upper ends of the base 1 and the heat-insulating wall 7 are jointly provided with a stable support frame layer 3 and a heat-insulating frame layer 4, and the heat-insulating frame layer 4 is located on the inner side of the stable support frame layer 3, the stable support frame layer 3 and the heat-insulating frame layer 4 are both composed of a support assembly and a plastic film, the double-arch design of the stable support frame layer 3 and the heat-insulating frame layer 4 is to enhance the stability and carrying capacity of the facility, so as to provide a relatively stable growth environment for crops, the top of the heat-insulating frame layer 4 is provided with a There is a thermal insulation quilt 5 for improving the thermal insulation effect of the thermal insulation frame layer 4. A water reservoir 10 is opened on the right side of the interior of the base 1, and the water reservoir 10 is located between the thermal insulation frame layer 4 and the stable support frame layer 3. A thermal insulation baffle 12 is vertically arranged on the inner side of the water reservoir 10. The thermal insulation baffle 12 separates the water reservoir 10 into a hot water thermal insulation chamber and a cold water chamber. The hot water thermal insulation chamber improves the thermal insulation effect by laying a protective layer and a thermal insulation layer on the inner wall, so as to distinguish it from the cold water chamber. A submersible pump 11 is arranged on the inner side of the hot water thermal insulation chamber. The submersible pump 11 can use a high-temperature resistant stainless steel submersible pump 11, which can maintain excellent corrosion resistance and mechanical properties in a high temperature environment, thereby ensuring the long-term stable operation of the submersible pump 11;

[0036] like Figure 2-Figure 4 As shown, a heat transfer mechanism 9 for geothermal heat is provided at the upper end of the base 1, and a heat collecting pipe group 6 located at the inner top of the stable support frame layer 3 is provided on the left side of the top of the water reservoir 10, and the water outlet and water inlet of the heat collecting pipe group 6 are extended into the hot water insulation cavity, and the water inlet of the heat collecting pipe group 6 is connected to the submersible pump 11, and the upper inclined part of the heat collecting pipe group 6 and the stable support frame layer 3 are close to each other but do not contact each other. Most of the components of the heat collecting pipe group 6 are distributed on the top of the stable support frame layer 3 in order to reduce the obstruction of light. In addition, the heat collecting pipe group 6 is made of a material with a certain degree of transparency, such as borosilicate glass and acrylic organic glass, which can allow most of the light to pass through and reduce the weakening of the light intensity, so that the greenhouse can collect heat energy while ensuring that enough light reaches the crops;

[0037] The upper end of the base 1 is provided with a support frame for limiting the position of the heat collecting tube group 6 and supporting the plastic film in the stable support frame layer 3, and the support frame is connected to the support component inside the stable support frame layer 3. The support frame is also composed of a plurality of transparent U-shaped brackets, which can not only assist the support component in the stable support frame layer 3 to support the plastic film and improve the stability of the stable support frame layer 3, but also protect the plastic film in the stable support frame layer 3 to prevent the plastic film from contacting the heat collecting tube group 6 that is heating up under the pressure of accumulated snow, causing deformation or even damage of the plastic film;

[0038] In addition, in order to maintain the temperature inside the greenhouse, an electric heater for heating the water source in the hot water insulation cavity is provided inside the stable support frame layer 3 to ensure that the hot water is reheated when the temperature of the hot water is insufficient in winter, so that the hot water temperature reaches the geothermal use standard;

[0039] As can be seen from the above, the submersible pump 11 works during the day, causing the water flow in the hot water insulation cavity to flow through the heat collection pipe group 6 to collect heat energy. By night, the hot water in the hot water insulation cavity flows through the heat transfer mechanism 9 to keep the inner side of the insulation frame layer 4 warm;

[0040] In addition, during snowy and rainy days in winter, the submersible pump 11 can also accelerate the melting speed of the snow on the surface of the stable support frame layer 3 by making the hot water flow through the heat collection pipe group 6, reducing the possibility of the greenhouse being collapsed by the accumulated snow. Since heat is transferred by radiation and convection, even without direct contact, the heat emitted by the heat collection pipe group 6 close to the flowing hot water can be transferred to the snow-covered area, raising the temperature of the surrounding environment and thus accelerating the melting of the snow.

[0041] Specifically, as Figure 4 and Figure 5 shown, the heat transfer mechanism 9 includes a water pump 98 inside the stable support frame layer 3, a circulation pipe 91 and a collecting pipe 94 inside the insulation frame layer 4. The water intake end of the water pump 98 is provided with a U-shaped water inlet pipe 97. The two vertical parts of the U-shaped water inlet pipe 97 extend into the hot water insulation cavity and the cold water cavity respectively. The horizontal part of the U-shaped water inlet pipe 97 is provided with two solenoid valves I for controlling the water inflow direction of the U-shaped water inlet pipe 97. The water outlet end of the water pump 98 is provided with a drain pipe I. A part of the drain pipe I away from the water pump 98 passes through the side wall of the insulation frame layer 4 and is connected to the circulation pipe 91. A number of geothermal pipes 92 are evenly arranged at the mutually adjacent ends of the circulation pipe 91 and the collecting pipe 94. During actual laying, a layer of sand can also be laid on the surface of the geothermal pipes 92 to reduce heat and moisture loss. The rear part of the upper end of the collecting pipe 94 is provided with a U-shaped diversion pipe 95. The U-shaped diversion pipe 95 is arranged at the top of the collecting pipe 94 to prevent the hot water from leaving in advance, so that the hot water in the geothermal pipes 92 is always in a full state, and further to avoid uneven hot water content in each geothermal pipe 92, resulting in temperature differences in each area on the inner side of the greenhouse. One end of the U-shaped diversion pipe 95 away from the collecting pipe 94 is provided with a drain pipe II 93. The right end of the drain pipe II 93 passes through the side wall of the stable support frame layer 3 and is provided with a U-shaped drain pipe 96. The two vertical parts of the U-shaped drain pipe 96 extend into the hot water insulation cavity and the cold water cavity respectively. The horizontal part of the U-shaped drain pipe 96 is provided with two solenoid valves II for controlling the drainage direction of the U-shaped drain pipe 96;

[0042] It can be seen from this that the water pump 98 first selects to extract hot water or cold water in the reservoir 10 according to the growth requirements of the crops by using the first electromagnetic valve, and then injects it into the circulation pipe 91 through the first drain pipe. After that, the water flow evenly disperses from the circulation pipe 91 into several geothermal pipes 92 to heat or cool the base 1. Then, the water flows in several geothermal pipes 92 all converge into the collecting pipe 94, and finally the water flow returns to the hot water insulation cavity and the cold water cavity through the U-shaped diversion pipe 95, the second drain pipe 93 and the U-shaped drain pipe 96. During this process, the water flow in each pipe component of the heat transfer mechanism 9 is always in a full state, so that the temperatures of each area inside the insulation frame layer 4 are kept consistent.

[0043] Specifically, as Figure 5 shown, a collecting mechanism 2 for supplementing the water source in the reservoir 10 is provided on the right side of the top of the reservoir 10 and extends to the outside of the stable support frame layer 3. The collecting mechanism 2 is composed of a water collecting tank 23 and three connecting pipes 22. The water collecting tank 23 is fixedly connected to the bottom outside the stable support frame layer 3 for receiving rainwater. The connecting pipes 22 are fixedly connected to the top wall of the reservoir 10 and communicate with the cold water cavity, so as to prevent the collected water flow from directly flushing against the hot water in the reservoir 10 and affecting the use of the hot water. A part of the connecting pipe 22 far from the reservoir 10 extends to the outside of the stable support frame layer 3 and is connected to the water collecting tank 23. A rotary seal cover is also provided at the connection part of the connecting pipe 22 and the water collecting tank 23 to reduce the loss of moisture and heat in the reservoir 10.

[0044] Therefore, the specific implementation manner of this embodiment is as follows:

[0045] When the sun is shining brightly, the submersible pump 11 transports the water flow in the hot water insulation cavity to the heat collecting pipe group 6 to flow and collect heat energy. When it comes to night, the water pump 98 extracts the hot water in the hot water insulation cavity through the U-shaped water inlet pipe 97 and the first electromagnetic valve, injects it into the circulation pipe 91 through the first drain pipe, and then the water flow evenly disperses from the circulation pipe 91 into several geothermal pipes 92 to heat the base 1. After that, the water flows in several geothermal pipes 92 all converge into the collecting pipe 94, and finally the water flow returns to the hot water insulation cavity through the U-shaped diversion pipe 95, the second drain pipe 93 and the U-shaped drain pipe 96, so as to keep the temperatures of each area inside the insulation frame layer 4 consistent and provide a relatively stable growth environment for the crops;

[0046] In addition, in winter rainy and snowy weather, the submersible pump 11 can also accelerate the melting speed of the snow on the surface of the stable support frame layer 3 by making the hot water flow in the heat collecting pipe group 6, reduce the possibility of the greenhouse being collapsed by the snow, and improve the practicability and reliability of the greenhouse.

[0047] Embodiment 2

[0048] This embodiment adds a swing mechanism 13, a temperature control mechanism 15 and a driving mechanism 17 on the basis of the first embodiment, so as to change the temperature of the ventilation airflow according to the growth requirements of the crops. Figure 4 , Figure 6 and Figure 7 As shown, a rectangular frame 14 is provided at the middle of the right end of the thermal insulation wall 7, and two swing mechanisms 13 for changing the blowing direction of the airflow are provided on the inner side of the rectangular frame 14. The swing mechanism 13 includes a fixed pipe 131 and a connecting pipe 133, and the connecting pipe 133 and the fixed pipe 131 do not contact each other. The connecting pipe 133 is located on the right side of the fixed pipe 131, and the fixed pipe 131 is fixedly connected to the thermal insulation wall 7. A rotating shaft 134 is provided between the parts of the fixed pipe 131 and the connecting pipe 133 that are close to each other, and the rotating shaft 134 is vertically rotatably connected to the inner side of the rectangular frame 14. An empty groove 16 is opened in the middle side of the inner part of the thermal insulation wall 7, and the fixed pipe 131 passes through The hollow groove 16 is connected to the heat preservation wall 7. A driving mechanism 17 for controlling the reciprocating rotation of the rotating shaft 134 is provided in the middle of the outer surface of the rotating shaft 134 and the inner side of the hollow groove 16. A rubber sleeve 132 is provided on a part of the outer surface of the fixed pipe 131 and the connecting pipe 133 close to each other. The rubber sleeve 132 is sleeved on the outer side of the rotating shaft 134 and is rotatably connected to the rotating shaft 134. L-shaped stabilizing frames 135 are provided on the top and bottom of the outer surface of the connecting pipe 133. The horizontal parts of the two L-shaped stabilizing frames 135 are fixedly connected to the rotating shaft 134. A temperature control mechanism 15 for changing the air flow temperature is provided at the right end of the connecting pipe 133.

[0049] It can be seen that when ventilation is required in the insulation frame layer 4, the insulation wall 7 works to blow air into the empty groove 16, and then the airflow enters the insulation frame layer 4 through the fixed pipe 131, the rubber sleeve 132 and the connecting pipe 133, thereby accelerating the air flow in the insulation frame layer 4, improving the air quality, and reducing the breeding of diseases. When the airflow flows in the empty groove 16, it will also drive the driving mechanism 17 to work, so that the driving mechanism 17 controls the connecting pipe 133 to swing around the rotating shaft 134 as the axis, changing the blowing direction of the airflow, thereby preventing some crops from being blown by the wind for a long time and causing lodging.

[0050] Specifically, Figure 7 and Figure 8As shown, the driving mechanism 17 includes a rotating rod 174 horizontally connected to the empty slot 16 and a telescopic rod 171 fixedly connected to the rotating shaft 134. The outer surface of the rotating rod 174 is provided with two turbines 175 symmetrically distributed with each other, and the turbine 175 is located between the insulation wall 7 and the fixed pipe 131, so that when the airflow disperses in the empty slot 16 and flows to the two swing mechanisms 13, the turbine 175 is blown to rotate. The two turbines 175 are provided to increase the rotational driving force of the rotating rod 174. The outer surface of the rotating rod 174 The front part of the surface and the rear part of the outer surface are both provided with an inclined annular groove 173, which can also be replaced by a reciprocating spiral groove structure. A part of the telescopic rod 171 away from the rotating shaft 134 passes through the fixed tube 131 and is provided with a rotating collar 172, which is rotatably connected to the telescopic rod 171. A part of the rotating collar 172 away from the telescopic rod 171 is sleeved on the outside of the rotating rod 174 and is slidably connected to the rotating rod 174. The inner surface of the rotating collar 172 is provided with a sliding ball slidably connected to the inclined annular groove 173.

[0051] It can be seen that when the airflow flows toward the swing mechanism 13, it will also blow the turbine 175 to rotate, and then the turbine 175 will drive the rotating rod 174 to rotate together, so that the rotating ring 172 can use the sliding ball to slide in the inclined ring groove 173 to move back and forth, and then the rotating ring 172 uses the extension of the telescopic rod 171 to pull the telescopic rod 171 to swing back and forth, so that the rotating shaft 134 can control the swing of the connecting tube 133 to continuously change the blowing direction of the airflow.

[0052] Specifically, Fig. 9 and Fig.10 As shown, the temperature control mechanism 15 includes a mounting box 152 fixedly connected to the connecting pipe 133, an adapter plate 153 is provided on the inner side of the mounting box 152, and two groups of cooling tube groups are provided on the upper end of the adapter plate 153. The cooling tube group consists of two storage tubes 155. The inner cavity of the storage tube 155 is filled with ethanol. The ethanol has strong volatility and can be re-condensed into liquid under the action of a simple cooling device. The upper ends of the two groups of cooling tube groups pass through the top wall of the mounting box 152 and are jointly provided with a liquefaction mechanism 154. The storage tube 155 is rotatably connected to the liquefaction mechanism 154 and the mounting box 152. The mounting box 152 The lower end of the heating tube group is provided with two groups of heating tube groups, which are composed of two storage tubes 156. The outer surfaces of the storage tubes 156 and 155 are provided with heat-conducting fins 159. The lower ends of the two groups of heating tube groups pass through the bottom wall of the installation box 152 and are jointly provided with a connecting box 151. The storage tube 156 is rotatably connected with the installation box 152 and the connecting box 151. The connecting box 151 can be temporarily fixed on the connecting box 151 by magnetic attraction or snap-on method. A rubber tube 157 is provided in the middle of the lower end of the connecting box 151. A part of the rubber tube 157 away from the connecting box 151 is connected to the collecting pipe 94 through a solenoid valve 3.

[0053] The ethanol exchanges heat with the outside through the heat-conducting fins 159, so that the ethanol itself is vaporized, thereby reducing the temperature of the heat-conducting fins 159, so that the heat-conducting fins 159 can effectively cool the airflow passing through;

[0054] Specifically, Fig.10 As shown, the left side wall of the installation box 152 is provided with two trapezoidal through slots 158 which penetrate the side wall of the installation box 152 horizontally, and the trapezoidal through slots 158 correspond to the gap between the two storage tubes 156 in the same group, so that the airflow can be heated or cooled by the heat-conducting fins 159 when leaving through the trapezoidal through slots 158. In addition, when the airflow blows over the heat-conducting fins 159, the heat-conducting fins 159 can also be used to drive the storage tube 1 155 or the storage tube 2 156 to rotate, so that each heat-conducting fin 159 can be kept at a higher or lower temperature for a long time, thereby effectively changing the temperature of the passing airflow, and then maintaining the stability of the airflow temperature;

[0055] Furthermore, the horizontal height of the adapter plate 153 is always less than the horizontal height of the upper horizontal portion of the U-shaped flow guide pipe 95, ensuring that the hot water in the collecting pipe 94 continuously enters the second storage pipe 156 without affecting the circulation flow, so that the heating pipe group can maintain a high temperature for a long time;

[0056] As can be seen from the above, when the temperature in the heat preservation frame layer 4 is too high, the liquefaction mechanism 154 is pressed to allow the storage tube 155 to enter the inner cavity of the installation box 152, and then when the airflow leaves through the trapezoidal through groove 158, the heat-conducting fins 159 are used to cool down the air, and the heat-conducting fins 159 are blown to drive the storage tube 155 to rotate, so that each heat-conducting fin 159 can maintain a low temperature for a long time, so that the heat-conducting fin 159 can effectively cool down the airflow passing through for a long time. At the same time, the cold water in the cold water cavity can also flow in the heat transfer mechanism 9 to assist the airflow in cooling down, speed up the cooling speed, and avoid high-temperature inactivation of crops;

[0057] When the humidity in the insulation rack layer 4 is heavy, open the solenoid valve three, so that the hot water in the collecting pipe 94 can enter the storage pipe 2 156 through the rubber tube 157 while circulating, and then repeat the above steps to ventilate and remove the moisture in the insulation rack layer 4 while maintaining the temperature in the insulation rack layer 4.

[0058] Specifically, Fig. 9As shown, the liquefaction mechanism 154 includes a thermal insulation box 1541, which is fixedly connected to the storage tube 155 and communicated with the storage tube 155. Four heat-conducting tubes 1542 are arranged side by side in the middle of the inner cavity of the thermal insulation box 1541. The inner cavity of the heat-conducting tube 1542 is filled with coolant. Any heat-conducting tube 1542 is located directly above one of the storage tubes 155, so that the gaseous ethanol can drip back into the storage tube 155 after contacting the heat-conducting tube 1542 and re-condensing into liquid droplets.

[0059] Therefore, the specific implementation of this embodiment is:

[0060] When the temperature in the insulation frame layer 4 is too high, the liquefaction mechanism 154 is pressed first to make the storage tube 155 enter the inner cavity of the installation box 152, and then the insulation wall 7 works to blow air into the empty slot 16, and when the airflow flows to the swing mechanism 13, it will also blow the turbine 175 to rotate, and then the turbine 175 will drive the rotating rod 174 to rotate together, so that the rotating ring 172 can use the sliding ball to slide in the inclined ring groove 173 to move forward and backward, and then the rotating ring 172 uses the telescopic rod 171 to pull the telescopic rod 171 to move forward and backward. 1 is swung back and forth, so that the rotating shaft 134 can control the connecting pipe 133 to swing to continuously change the blowing direction of the airflow, so as to prevent some crops from being blown by the wind for a long time and falling over. After that, when the airflow leaves through the trapezoidal through groove 158, the heat-conducting fins 159 are used to cool down the airflow, and the heat-conducting fins 159 are blown to drive the storage tube 155 to rotate, so that each heat-conducting fin 159 can maintain a low temperature for a long time, so that the heat-conducting fin 159 can effectively cool down the airflow passing through for a long time;

[0061] When the humidity in the insulation rack layer 4 is heavy, the storage tube 2 156 is first pushed upward through the connecting box 151 to enter the inner cavity of the installation box 152, and then the solenoid valve 3 is opened, so that the hot water in the collecting pipe 94 can circulate and enter the storage tube 2 156 through the rubber tube 157. Thereafter, the above steps are repeated to ventilate and remove the moisture in the insulation rack layer 4 while maintaining the temperature in the insulation rack layer 4.

It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
