Description

Technical Field

[0001] The present invention relates to the technical field of greenhouses, and in particular to a greenhouse with a temperature regulating function. Background Art

[0002] With the development of modern agriculture, solar greenhouses are important facilities for off-season planting, and their thermal insulation performance directly affects the growth and yield of crops. Although traditional earth-walled greenhouses have good thermal insulation and heat storage effects, they are costly, complex to construct, and have low land utilization rates. In recent years, all-steel frame solar greenhouses that use floor-standing steel frames as load-bearing structures and use rubber and plastic, thermal insulation boards, thermal insulation blankets and other thermal insulation materials as wall materials have been rapidly promoted.

[0003] The advantages of the all-steel solar greenhouse are fast construction, less civil engineering, and low overall cost; the thinner wall structure greatly improves land utilization. However, the performance characteristics of the all-steel solar greenhouse, which is "focused on heat preservation and light on heat storage", make it difficult to meet the winter production of thermophilic crops.

[0004] In addition, in order to maintain the temperature in the greenhouse at night, a thermal insulation curtain is usually laid on the top of the greenhouse. The traditional method of retracting and releasing the thermal insulation curtain mainly uses a winch to release or retract the thermal insulation curtain. One end of the thermal insulation curtain slides down along the slope of the greenhouse by its own weight and finally covers the top of the greenhouse.

[0005] However, this traditional method has some obvious problems. Due to the friction between the insulation curtain and the greenhouse film when it slides down, and the influence of other factors such as wind, the insulation curtain is often difficult to lay neatly in the designated position during the sliding process, and it is easy to be skewed. This not only affects the insulation effect, but also affects the overall appearance of the greenhouse.

[0006] In order to solve the problem of irregular laying of thermal insulation curtains, manual adjustment is generally required. This not only increases labor costs, but also has low work efficiency and cannot meet the needs of efficient production in modern agriculture.

[0007] Therefore, the development of a greenhouse with temperature regulation function and the ability to automatically and regularly lay thermal insulation curtains has become an urgent need in the current agricultural field. Summary of the invention

[0008] The present invention provides a greenhouse with a temperature regulating function, which solves the problem in the related art that the thermal insulation curtain is easily skewed during laying and needs manual adjustment.

[0009] The technical solution of the present invention is as follows: A greenhouse with a temperature regulation function, comprising a wall, a frame, a light-transmitting film, a thermal insulation curtain and a winding shaft, wherein the frame is arranged on the wall, the light-transmitting film is laid on the frame, the winding shaft is arranged to rotate and move relative to the frame, one end of the thermal insulation curtain is fixed to the top of the wall, and the other end is arranged on the winding shaft, and after the winding shaft rotates and moves, it is used to spread or roll up the thermal insulation curtain.

[0010] Optionally, it further includes a movable frame, which is slidably arranged on the frame, and the winding shaft is rotatably arranged on the movable frame.

[0011] Optionally, it also includes a gear and a rack, wherein the gear is coaxially arranged on the winding shaft, the rack is arranged on the frame, and the gear is meshed with the rack.

[0012] Optionally, it also includes a fixing plate and fixing bolts, wherein the fixing plate is arranged on the top of the wall with the aid of the fixing bolts, and the fixing plate is used to press the top of the thermal insulation curtain.

[0013] Optionally, the skeleton has a ventilation channel inside, and the skeleton surface has air outlet holes, the air outlet holes are connected to the ventilation channel, there are multiple air outlet holes, the air outlet holes are facing the light-transmitting film, and also includes a fan, which is provided on the skeleton and is used to supply air to the ventilation channel.

[0014] Optionally, the wall includes a thermal insulation layer, a main body layer and a heat collecting layer from the outside to the inside.

[0015] Optionally, it also includes a water distributor, a heat collecting and circulating water pipe and a temperature sensor, wherein the water distributor and the temperature sensor are both arranged on the heat collecting and circulating heat layer, the heat collecting and circulating heat layer has a pipe groove, the heat collecting and circulating heat pipe is embedded in the pipe groove, and both ends of the heat collecting and circulating heat pipe are connected to the water distributor.

[0016] Optionally, the heat collecting and dissipating circulating water pipe is in a coiled shape.

[0017] Optionally, it also includes a water storage unit, a circulation pump and a valve. The water storage unit is arranged on one side of the greenhouse. The water storage unit and the water distributor are connected by a pipeline. The circulation pump and the valve are both arranged on the pipeline.

[0018] Optionally, it also includes an electric heating rod, which is arranged in the water storage unit.

[0019] The working principle and beneficial effects of the present invention are: The walls and frames form the main structure of the greenhouse. A light-transmitting film is laid on the frame to ensure sufficient light in the greenhouse. One end of the thermal insulation curtain is fixed to the top of the wall, and the other end is connected to a rotatable and movable winding shaft.

[0020] When the thermal curtain needs to be laid for nighttime heat preservation, the winding shaft starts to roll downward from the top of the greenhouse. As the winding shaft moves along a specific trajectory, the thermal curtain is gradually spread out as the winding shaft rolls. In this process, the thermal curtain can be evenly covered on the top of the greenhouse without any skew. The moving trajectory of the winding shaft ensures the regularity of the laying of the thermal curtain without manual adjustment. When the thermal curtain needs to be rolled up during the day, the winding shaft rolls upward. During the rolling process, the thermal curtain is gradually rolled up until the winding shaft returns to the top of the greenhouse and the thermal curtain is rolled up again.

[0021] First, the movable and rotatable winding shaft effectively solves the problem of the traditional thermal insulation curtain being easily skewed. The specific moving track of the winding shaft ensures that the thermal insulation curtain can be laid neatly on the top of the greenhouse, greatly improving the insulation effect and the overall aesthetics of the greenhouse. Secondly, there is no need for manual post-adjustment, which saves a lot of labor costs. This makes greenhouse management more efficient and meets the needs of efficient production in modern agriculture. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0027] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0029] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, proposes a greenhouse with temperature regulation function, including a wall 1, a frame 2, a light-transmitting film 3, a thermal insulation curtain 4 and a winding shaft 5, wherein the frame 2 is arranged on the wall 1, the light-transmitting film 3 is laid on the frame 2, the winding shaft 5 is arranged to rotate and move relative to the frame 2, one end of the thermal insulation curtain 4 is fixed to the top of the wall 1, and the other end is arranged on the winding shaft 5. After the winding shaft 5 rotates and moves, it is used to spread or roll up the thermal insulation curtain 4.

[0030] In this embodiment, the wall 1 and the frame 2 constitute the main structure of the greenhouse. A light-transmitting film 3 is laid on the frame 2 to ensure sufficient light in the greenhouse. One end of the thermal insulation curtain 4 is fixed to the top of the wall 1, and the other end is connected to a rotatable and movable winding shaft 5.

[0031] When it is necessary to lay the thermal insulation curtain 4 for nighttime insulation, the winding shaft 5 starts to roll downward from the top of the greenhouse. Since the winding shaft 5 moves along a specific trajectory, the thermal insulation curtain 4 is gradually spread out as the winding shaft 5 rolls. In this process, the thermal insulation curtain 4 can evenly cover the top of the greenhouse without being skewed. The moving trajectory of the winding shaft 5 ensures the regularity of the laying of the thermal insulation curtain 4, and no manual adjustment is required later. When the thermal insulation curtain 4 needs to be rolled up during the day, the winding shaft 5 rolls upward. During the rolling process, the thermal insulation curtain 4 is gradually rolled up until the winding shaft 5 is reset to the top of the greenhouse, and the thermal insulation curtain 4 is rolled up again.

[0032] First, the movable and rotatable winding shaft 5 effectively solves the problem that the traditional thermal insulation curtain 4 is easily skewed during laying. The specific moving trajectory of the winding shaft 5 ensures that the thermal insulation curtain 4 can be laid neatly on the top of the greenhouse, greatly improving the insulation effect and the overall aesthetics of the greenhouse. Secondly, there is no need for manual post-adjustment, which saves a lot of labor costs. This makes the management of the greenhouse more efficient and meets the needs of efficient production in modern agriculture.

[0033] Furthermore, it also includes a movable frame 6, which is slidably disposed on the frame 2, and the winding shaft 5 is rotatably disposed on the movable frame 6.

[0034] Furthermore, it also includes a gear 7 and a rack 8, wherein the gear 7 is coaxially arranged on the winding shaft 5, and the rack 8 is arranged on the skeleton 2, and the gear 7 is meshed with the rack 8.

[0035] In this embodiment, a moving frame 6, a gear 7 and a rack 8 are additionally provided. A sliding groove is provided on the frame 2, and the moving frame 6 is located in the sliding groove. When the thermal insulation curtain 4 needs to be laid or rolled up, the moving frame 6 slides in the sliding groove according to a predetermined track to provide a stable moving support for the winding shaft 5. The winding shaft 5 is rotatably arranged on the moving frame 6 and moves with the movement of the moving frame 6.

[0036] Since the closer the winding shaft 5 is to the top of the greenhouse, the thicker the thermal insulation curtain 4 will be wound and the higher its height is, the sliding groove is designed accordingly according to the increasingly higher trajectory of the winding shaft 5. At the same time, the gear 7 is coaxially arranged on the winding shaft 5, and the rack 8 is arranged on the frame 2, and the gear 7 is meshed with the rack 8. The gear 7 is driven to rotate by the motor installed on the mobile frame 6, and in the meshing relationship with the rack 8, the gear 7 rolls on the rack 8. Since the winding shaft 5 and the gear 7 are coaxially arranged, the winding shaft 5 is driven to roll.

[0037] When the thermal insulation curtain 4 needs to be laid, the motor starts, the driving gear 7 rolls on the rack 8, and drives the winding shaft 5 to roll downward from the top of the greenhouse along the sliding groove along the moving frame 6. As the winding shaft 5 rolls, the thermal insulation curtain 4 is gradually spread out and evenly covers the top of the greenhouse. When the thermal insulation curtain 4 needs to be rolled up, the motor reverses, the driving gear 7 rolls in the opposite direction, drives the winding shaft 5 and the moving frame 6 to move upward, and the thermal insulation curtain 4 is gradually rolled up until the winding shaft 5 is reset to the top of the greenhouse.

[0038] First, the moving frame 6 moves in the sliding groove of the frame 2, providing a stable moving track for the winding shaft 5, ensuring that the winding shaft 5 runs stably during the process of laying and rolling up the thermal insulation curtain 4, and further improving the regularity of laying the thermal insulation curtain 4. Secondly, the sliding groove is designed according to the height change track of the winding shaft 5, adapting to the height change of the winding shaft 5 caused by the thickness change of the thermal insulation curtain 4, making the entire system more reasonable and efficient.

[0039] Furthermore, it also includes a fixing plate 9 and a fixing bolt 10 , wherein the fixing plate 9 is arranged on the top of the wall 1 by means of the fixing bolt 10 , and the fixing plate 9 is used to press the top end of the thermal insulation curtain 4 .

[0040] In this embodiment, under the action of the fixing bolts 10, the fixing plate 9 presses the top of the thermal insulation curtain 4 to position it on the top of the wall 1, ensuring that the thermal insulation curtain 4 will not fall off from the top of the wall 1 during the rolling of the winding shaft 5.

[0041] First, by using the fixing plate 9 and the fixing bolts 10 in combination, the top of the heat-insulating curtain 4 can be firmly fixed to prevent the heat-insulating curtain 4 from falling off during the laying and rolling process, thereby ensuring the stability and reliability of the system. Secondly, the fixing plate 9 and the fixing bolts 10 have a simple structure, are easy to install, and have a low cost, and can effectively improve the temperature regulation effect of the greenhouse, providing a more stable environment for the growth of crops.

[0042] Furthermore, the skeleton 2 has a ventilation channel 11 inside, and the surface of the skeleton 2 has air outlet holes 12, which are connected to the ventilation channel 11. There are multiple air outlet holes 12, and the air outlet holes 12 face the light-transmitting film 3. It also includes a fan 13, which is arranged on the skeleton 2 and is used to supply air to the ventilation channel 11.

[0043] In this embodiment, when the environmental conditions inside the greenhouse may cause fogging or condensation on the inner surface of the light-transmitting film 3, the fan 13 is started to supply air into the ventilation channel 11. Driven by the fan 13, the airflow flows along the ventilation channel 11 and is ejected from a plurality of air outlets 12, directly spraying on the inner surface of the light-transmitting film 3. These airflows can promptly take away the fog or water droplets that may be formed on the inner surface of the light-transmitting film 3, and maintain a good light transmission effect of the light-transmitting film 3. When the humidity inside the greenhouse is high or the temperature changes greatly, the fan 13 can continue to run for a period of time to ensure that the inner surface of the light-transmitting film 3 always remains dry and clear. The direction of the air outlet 12 is designed to be inclined toward the inner surface of the light-transmitting film 3, which can effectively remove fog and condensation without causing damage to the light-transmitting film 3.

[0044] First, the fan 13 supplies air to the ventilation channel 11, and the airflow ejected from the air outlet 12 prevents fogging or condensation on the inner surface of the light-transmitting film 3, thereby ensuring that the greenhouse always has a good light-transmitting effect, providing sufficient light for the crops, and facilitating the growth and development of the crops. Second, this design can automatically adjust the surface state of the light-transmitting film 3 without manual intervention, thereby improving the management efficiency of the greenhouse.

[0045] Furthermore, the wall 1 includes a heat-insulating layer 14 , a main body layer 15 and a heat-collecting layer 16 in sequence from the outside to the inside.

[0046] Furthermore, it also includes a water separator 17, a heat collecting and circulating water pipe 18 and a temperature sensor 19, the water separator 17 and the temperature sensor 19 are both arranged on the heat collecting and circulating heat layer 16, the heat collecting and circulating heat layer 16 has a pipe groove 20, the heat collecting and circulating heat pipe 18 is embedded in the pipe groove 20, and both ends of the heat collecting and circulating heat pipe 18 are connected to the water separator 17.

[0047] Furthermore, the heat collecting and cooling circulating water pipe 18 is in a coiled shape.

[0048] In this embodiment, the wall 1 includes a heat-insulating layer 14, a main body layer 15 and a heat-collecting layer 16 from the outside to the inside. The main body layer 15 provides the wall 1 with necessary strength support to ensure the stability of the greenhouse structure. The heat-insulating layer 14 can effectively reduce the heat loss in the greenhouse and maintain the temperature in the greenhouse at night or in a low temperature environment. The heat-collecting layer 16 plays an important role in temperature regulation.

[0049] The heat collecting layer 16 is provided with a water divider 17 and a temperature sensor 19. The heat collecting layer 16 has a pipe groove 20. The coiled heat collecting and cooling circulating water pipe 18 is embedded in the pipe groove 20, and both ends of the heat collecting and cooling circulating water pipe 18 are connected to the water divider 17. The temperature sensor 19 can be installed on the heat collecting layer 16. In daily use, the temperature sensor 19 pre-sets the heat collecting temperature and the heat dissipation temperature. When the temperature sensor 19 detects that the temperature in the greenhouse exceeds the heat collecting temperature, it means that the sunlight is strong at this time. The system will automatically open the circulation, so that the water in the heat collecting and cooling circulating water pipe 18 starts to flow for heat collection. In the process of flowing in the heat collecting and cooling circulating water pipe 18, the water absorbs the heat in the greenhouse to achieve the effect of heat storage. When the temperature sensor 19 detects that the temperature in the greenhouse is lower than the heat dissipation temperature, the system opens the circulation again. At this time, the hot water in the heat collecting and cooling circulating water pipe 18 will dissipate the heat into the greenhouse, increase the temperature in the greenhouse, and thus ensure the temperature stability in the greenhouse.

[0050] Since the heat collecting and cooling circulating water pipe 18 is in a coiled shape, the occupied space is reduced within a limited space, while the total area of ​​the heat collecting and cooling circulating water pipe 18 installed on the heat collecting and cooling layer 16 is increased, thereby improving the efficiency of heat collecting and cooling.

[0051] First, the layered structure of the wall 1 is reasonably designed. The main layer 15 ensures the strength of the wall 1, the insulation layer 14 reduces heat loss, and the heat collecting and dissipating layer 16 realizes temperature regulation. The functions of each layer are clear and work together to provide a stable environment for the greenhouse. Secondly, through the cooperation of the temperature sensor 19 and the heat collecting and dissipating circulating water pipe 18, heat can be automatically collected and dissipated according to the temperature in the greenhouse, realizing intelligent temperature regulation, reducing manual intervention, and improving the efficiency of greenhouse management. Finally, the coiled design of the heat collecting and dissipating circulating water pipe 18 saves space, increases the area of ​​heat collection and dissipation, and improves energy efficiency.

[0052] Furthermore, it also includes a water storage unit 21, a circulation pump 22 and a valve 23. The water storage unit 21 is arranged on one side of the greenhouse. The water storage unit 21 has an outlet pipe and a return pipe. The outlet pipe and the return pipe are both connected to the water distributor 17. The circulation pump 22 and the valve 23 are both arranged on the outlet pipe.

[0053] Furthermore, it also includes an electric heating rod 24 , which is arranged in the water storage unit 21 .

[0054] In this embodiment, the water storage unit 21 is arranged in the underground soil on one side of the greenhouse, and has a water outlet pipe and a water return pipe. The water outlet pipe and the water return pipe can also be arranged in the underground soil. The water outlet pipe and the water return pipe are both connected to the water distributor 17, so as to realize the circulation connection between the water storage unit 21 and the heat collection and heat dissipation circulation water pipe 18. Under normal circumstances, when heat collection or heat dissipation circulation is required, the valve 23 is opened and the circulation pump 22 is started. The circulation pump 22 provides power for the water circulation, so that the water circulates among the water storage unit 21, the water outlet pipe, the water distributor 17, the heat collection and heat dissipation circulation water pipe 18, and the water return pipe.

[0055] When the sunlight is strong, the water in the heat collecting and circulating water pipe 18 absorbs heat and the temperature gradually rises. At the same time, the water storage unit 21 buried in the underground soil of the greenhouse is also connected to the heat collecting and circulating water pipe 18 through the outlet pipe, return pipe and water distributor 17. At this time, the hot water in the heat collecting and circulating water pipe 18 flows into the water storage unit 21, and the heat is stored in the underground soil.

[0056] At night or when the temperature is low, the temperature in the greenhouse begins to drop. When the temperature sensor 19 detects that the temperature is lower than the heat dissipation temperature, the control system starts the circulation pump 22 to circulate the water in the water storage unit 21. Hot water flows out of the water storage unit 21 in the underground soil, flows into the heat collection and heat circulation water pipe 18 through the water distributor 17, and releases the heat brought by the water storage unit 21 into the greenhouse, raising the greenhouse temperature and providing a suitable growth environment for thermophilic crops.

[0057] When there is continuous cloudy weather without sunlight, the temperature in the greenhouse may drop. At this time, the electric heating rod 24 in the water storage unit 21 is started. The electric heating rod 24 starts to work and heats the water in the water storage unit 21. Under the action of the circulation pump 22, the heated water flows into the water distributor 17 through the outlet pipe, and then enters the heat collecting and circulating water pipe 18 to dissipate the heat into the greenhouse, thereby serving as an auxiliary warming measure to ensure that the temperature in the greenhouse is stable within a range suitable for the growth of crops.

[0058] First, the arrangement of the water storage unit 21, the circulation pump 22 and the valve 23 ensures that the water circulation in the heat collection and heat circulation water pipe 18 is stable, and can collect and dissipate heat in time as needed, thereby improving the efficiency and reliability of temperature regulation. Secondly, the arrangement of the electric heating rod 24 provides an auxiliary warming measure for the greenhouse under special circumstances such as continuous cloudy days, ensuring that the temperature in the greenhouse will not be too low, providing a stable environment for the growth of crops, and reducing the adverse effects of weather factors on agricultural production.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
