Technical Field
[0001] The invention relates to the technical field of greenhouses, and in particular to an assembled solar greenhouse. Background Art
[0002] Solar greenhouse is the abbreviation of energy-saving solar greenhouse, also known as warm shed, which consists of two side gables, a protective back wall, a supporting frame and covering materials. It is a type of greenhouse unique to northern my country. It is a greenhouse that is not heated indoors. It stores and releases heat by absorbing solar energy through the back wall, maintaining a certain temperature level indoors to meet the needs of vegetable crop growth; some farmers also add heating measures in the greenhouse, such as stoves, boilers, heating pipes, or night insulation measures, such as rolling curtains and quilts.
[0003] In order to ensure the growth environment of plants, most solar greenhouses are equipped with upwind vents for ventilation and to improve the environment inside the solar greenhouse. It is common in the market to set up a film rolling machine on the outside of the upwind vents. However, in extreme weather conditions, such as snowy days and rainy days, farmers must maintain the moisture balance inside the greenhouse to ventilate the greenhouse, and prevent heavy snow and rain from entering the greenhouse through the upwind vents, which leads to drawbacks in the upwind vent control of traditional greenhouses. Summary of the invention
[0004] The invention discloses an assembled solar greenhouse, which aims to solve the technical problem that in extreme weather, traditional greenhouse upwind vents cannot both maintain the moisture balance inside the greenhouse and prevent heavy snow and rainwater from flowing back into the greenhouse through the upwind vents, thus resulting in disadvantages in use.
[0005] In order to achieve the above object, the present invention adopts the following technical solutions:
[0006] An assembled solar greenhouse, comprising a shed main body, a greenhouse film covering the outside of the shed main body, and an upper wind port opened on the top and side of the shed main body, a ventilation mechanism is arranged on the outside of the upper wind port, the ventilation mechanism comprises a type of telescopic rod rotatably mounted on the side of the shed main body, a first film rolling device is sleeved on the top of the type of telescopic rod, a first wind port film is laid on the top of the upper wind port located above the shed main body, and the first wind port film is coiled on the outside of the output end of the first film rolling device;
[0007] A driving mechanism for changing the shape of the ventilation mechanism is arranged on the outer side of one of the upper tuyere, the driving mechanism comprising a plurality of connecting plates fixedly mounted on the top of the scaffold body, and the first tuyere membrane is laid on the top of the connecting plates;
[0008] The ventilation mechanism controls the opening and closing of the upper air vent to ventilate the interior of the scaffolding body. The driving mechanism that operates synchronously in rainy and snowy weather can change the operating state of the ventilation mechanism, thereby adapting to the weather conditions to protect the scaffolding body from rain, snow and ventilation.
[0009] By providing a ventilation mechanism at the upwind vent of a traditional solar greenhouse, the ventilation mechanism operating under normal conditions can cooperate with the upwind vent to control the ventilation work inside the scaffolding body, thereby providing the necessary environment for the growth of vegetation. In extreme weather such as rain and snow, the driving mechanism additionally provided at the top of the upper vent can be started in cooperation with the control of the operator, and push the ventilation mechanism placed on the top to deform in the form of expansion, thereby pushing down the rain and snow accumulated on the top of the ventilation mechanism. At the same time, the scaffolding body is ventilated through the side opening, preventing rain and snow from entering the scaffolding body, while controlling the temperature and humidity inside the scaffolding body, thereby greatly improving the functionality and applicability of the solar greenhouse.
[0010] In a preferred embodiment, the ventilation mechanism also includes a sliding rod fixedly installed on the side of the scaffolding body, a second film rolling device is slidably sleeved on the outer side of the sliding rod, a second air outlet film is placed on the outer side of the upper air outlet located on the side of the scaffolding body, and the second air outlet film is coiled on the outer side of the output end of the second film rolling device.
[0011] Two groups of vent film structures are arranged at the upper opening, and two film rollers are used to respectively roll up the two groups of vent films. A type of telescopic rod, a sliding rod and the connection relationship between the first film roller and the second film roller are coordinated to ensure reasonable and perfect operation. Under normal circumstances, the winding of the vent film is used to control the closing of the upper vent, so as to ventilate the solar greenhouse and provide the necessary environment for the growth of vegetation.
[0012] In a preferred embodiment, the driving mechanism also includes a steel plate member rotatably installed at one end of the interior of each connecting plate, and a straight rod member is installed at the end of the steel plate member, and the straight rod member is hidden inside the connecting plate. The ends of several connecting plates are jointly sleeved on a connecting rod, and the connecting rod passes through the ends of several straight rod members. An electric push rod is fixedly installed on the top of the scaffolding body, and the output end of the electric push rod is connected to the end of the connecting rod.
[0013] By providing a plurality of groups of connecting plate structures fixed on the first tuyere membrane and the top of the scaffolding body, an electric push rod is used to push the connecting rod, causing the connecting rod to squeeze the straight rod member and push the steel plate member, causing the deformed steel plate member to arch, pushing the laid first tuyere membrane to bulge synchronously, thereby pushing down the rain and snow accumulated on the top of the first tuyere membrane, while opening the upper tuyere from the end to ventilate the interior of the scaffolding body, ensuring that the interior of the scaffolding body can be ventilated normally in rainy and snowy weather, thereby maintaining the temperature and humidity balance inside the body, greatly improving the functionality and applicability of the solar greenhouse.
[0014] In a preferred solution, a heat preservation mechanism is provided on the top of the scaffold body;
[0015] The heat preservation mechanism includes two types of telescopic rods rotatably installed on the side of the scaffolding body, the top of the two types of telescopic rods is sleeved with a third film roll, and a quilt is rolled up on the top of the scaffolding body, and the quilt is sleeved on the outer side of the output end of the third film roll.
[0016] By providing a quilt rolled up on the top of the solar greenhouse and using the third film roll to roll up the quilt, the temperature inside the shed body can be maintained in cold weather, thereby ensuring that the shed body can provide a benign environment for the growth of vegetation and ensuring the stable operation of the solar greenhouse.
[0017] In a preferred solution, a thermal insulation layer is provided on one side of the bottom of the scaffolding body, an anti-aging thermal insulation layer is fixed inside the scaffolding body, a reflective heat insulation layer is provided on one side of the anti-aging thermal insulation layer close to the thermal insulation layer, a hollow air layer is formed between the reflective heat insulation layer and the thermal insulation layer, and a nano-metal film heat absorption coating thermal collector plate is installed on the other side of the anti-aging thermal insulation layer.
[0018] By arranging a thermal insulation layer on one side of the bottom of the scaffolding body, the heat loss inside the scaffolding body is reduced, and an anti-aging thermal insulation layer is fixed inside the scaffolding body to increase the service life of the equipment material in an open-air exposure environment. At the same time, a reflective insulation layer is arranged on the side of the anti-aging thermal insulation layer close to the thermal insulation layer. A hollow air layer is formed between the reflective insulation layer and the thermal insulation layer, which has a good heat insulation effect. At the same time, an additional nano-metal film heat-absorbing coating collector plate is arranged to achieve a uniform water flow effect.
[0019] In a preferred embodiment, the heat-insulating and cold-proof layer includes two layers of woven cloth fixed to the outside of the scaffolding body, the inside of the woven cloth is mixed with pearl cotton and thermal insulation felt, and composite space cotton is fixed between the pearl cotton and the thermal insulation felt.
[0020] The thermal insulation and cold-proof layer is composed of woven cloth, pearl cotton, composite space cotton and thermal insulation felt; the woven cloth is made of a new polypropylene material with special processes such as anti-ultraviolet and anti-oxidation, and is woven after drawing. Because it has anti-ultraviolet function, it has a long service life. The service life can reach more than 10 years in an open-air exposure environment. It has the effects of not easy to penetrate water, long anti-aging time and good snow resistance. Pearl cotton (polyethylene foam cotton) is a non-cross-linked closed-cell structure, which is composed of countless independent bubbles produced by physical foaming of low-density polyethylene resin. It has good waterproof and moisture-proof, shockproof, sound insulation, heat preservation, and plasticity. It has many advantages such as strong toughness, recycling, environmental protection, and strong impact resistance. The composite space cotton is made of natural cotton fiber, man-made fiber and synthetic fiber through loosening, combing, web laying, glue spraying, drying and curing. It has the characteristics of fluffy, high compression rebound, moisture resistance, light weight and thermal insulation. It has excellent thermal insulation performance, good corrosion resistance, quick drying and better thermal insulation performance. Among them, thermal insulation felt is a kind of felt specially used for insulation of greenhouse vegetables. It is made by randomly arranging textile staple fibers to form a fiber mesh structure, and then reinforced by mechanical and hot bonding methods. It has strong corrosion resistance, good drainage performance, high tensile strength, long anti-aging time and good thermal insulation performance.
[0021] In a preferred embodiment, the reflective heat-insulating layer comprises two layers of pure aluminum foil, two layers of vacuum polyethylene bubble layers are sandwiched inside the pure aluminum foil, and polyethylene adhesive layers are filled between the vacuum polyethylene bubble layers.
[0022] By setting the reflective insulation layer to consist of pure aluminum foil, vacuum polyethylene bubble layer and polyethylene adhesive layer, the surface pure aluminum foil can directly reflect the conduction of heat, the bottom pure aluminum foil blocks the last part of the heat, and the insulation effect is better, while the middle vacuum polyethylene bubble layer has good thermal insulation effect.
[0023] As can be seen from the above, the assembled solar greenhouse provided by the present invention has the following improvements and advantages compared with the prior art:
[0024] First, two groups of vent membrane structures are arranged at the upper opening, and two film rollers are used to respectively roll up the two groups of vent membranes, and the connection relationship between a type of telescopic rod, a sliding rod and the first film roller and the second film roller is coordinated to ensure reasonable and perfect operation. Under normal circumstances, the winding of the vent membrane is used to control the closing of the upper vent, so as to ventilate the solar greenhouse and provide the necessary environment for the growth of vegetation. At the same time, several groups of connecting plate structures fixed to the first vent membrane and the top of the scaffolding body are additionally provided. The electric push rod is used to push the connecting rod, so that the connecting rod squeezes the straight rod member to push the steel plate member, so that the deformed steel plate member arches, and pushes the laid first vent membrane to synchronously bulge upward, thereby pushing down the rain and snow accumulated on the top of the first vent membrane, and at the same time, opening the upper vent from the end to ventilate the interior of the scaffolding body, ensuring that the interior of the scaffolding body can be ventilated normally in rainy and snowy weather, thereby maintaining the temperature and humidity balance inside the body, and greatly improving the functionality and scope of application of the solar greenhouse.
[0025] Secondly: by setting a thermal insulation layer on one side of the bottom of the scaffolding body, the heat loss inside the scaffolding body is reduced, and an anti-aging thermal insulation layer is fixed inside the scaffolding body to increase the service life of the equipment material in an open-air exposure environment. At the same time, a reflective insulation layer is set on the side of the anti-aging thermal insulation layer close to the thermal insulation layer. A hollow air layer is formed between the reflective insulation layer and the thermal insulation layer, which has a good heat insulation effect. At the same time, an additional nano-metal film heat-absorbing coating collector plate is set to achieve a uniform water flow effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0040] Reference Figures 1 to 12, an assembled solar greenhouse, comprising a shed body 1, a shed film 2 covering the outside of the shed body 1, and an upper air vent 3 opened on the top and side of the shed body 1, a ventilation mechanism 4 is arranged on the outside of the upper air vent 3, the ventilation mechanism 4 comprises a type of telescopic rod 401 rotatably mounted on the side of the shed body 1, a first film roll 402 is sleeved on the top of the type of telescopic rod 401, a first air vent film 403 is laid on the top of the upper air vent 3 above the shed body 1, and the first air vent film 403 is coiled on the outside of the output end of the first film roll 402;
[0041] A driving mechanism 5 for changing the shape of the ventilation mechanism 4 is arranged outside an upper air outlet 3, and the driving mechanism 5 includes a plurality of connecting plates 501 fixedly mounted on the top of the scaffolding body 1, and the first air outlet membrane 403 is laid on the top of the connecting plate 501;
[0042] The ventilation mechanism 4 controls the opening and closing of the upper air vent 3 to ventilate the interior of the scaffolding body 1. The driving mechanism 5 that operates synchronously in rainy and snowy weather can change the operating state of the ventilation mechanism 4, thereby adapting to the weather conditions to protect the scaffolding body 1 from rain, snow and ventilation.
[0043] In this embodiment: the ventilation mechanism 4 is started and rolled up along the outer side of the upwind vent 3, while exposing the upwind vent 3 to ventilate the interior of the scaffolding body 1; in rainy and snowy weather, the top of the ventilation mechanism 4 is covered with accumulated rain and snow, and the ventilation mechanism 4 cannot be directly rolled up. At this time, the operator controls the driving mechanism 5 to operate, and the driving mechanism 5 expands, thereby pushing the ventilation mechanism 4, causing the ventilation mechanism 4 to bulge outward, while bulging, the rain and snow accumulated on the top will slide down along the surface of the shed film 2, and at the same time, an opening will be formed on the end face of the driving mechanism 5, thereby ventilating the interior of the scaffolding body 1.
[0044] In the above scheme, considering the need to ensure the growth environment of plants and provide sufficient oxygen for vegetation growth, the specific operations are as follows.
[0045] Reference Figures 1 to 4 , Figure 6 , Fig. 9 In a preferred embodiment, the ventilation mechanism 4 also includes a sliding rod 404 fixedly installed on the side of the scaffolding body 1, and a second film rolling device 405 is slidably sleeved on the outer side of the sliding rod 404, and a second air outlet membrane 406 is placed on the outer side of the upper air outlet 3 located on the side of the scaffolding body 1, and the second air outlet membrane 406 is coiled on the outer side of the output end of the second film rolling device 405.
[0046] In this embodiment: the first film roller 402 and the second film roller 405 are started and rolled up along the outer side of the upper air outlet 3. While the first film roller 402 rolls up the first air outlet film 403, it moves along the top of the scaffolding body 1, and at the same time, a type of telescopic rod 401 will adaptively retract. While the second film roller 405 rolls up the second air outlet film 406, it moves vertically along the outer side of the sliding rod 404, thereby exposing the two upper air outlets 3 to ventilate the interior of the scaffolding body 1.
[0047] In the above scheme, considering that in rainy and snowy weather, the top of the first vent membrane 403 is covered with accumulated rain and snow, the first vent membrane 403 cannot be rolled up directly, but the temperature and humidity balance inside the scaffolding body 1 needs to be maintained, and the specific operation is as follows.
[0048] Reference Figures 2 to 3 , Figures 6 to 10 In a preferred embodiment, the driving mechanism 5 also includes a steel plate 502 rotatably installed at one end of each connecting plate 501, and a straight rod 503 is installed at the end of the steel plate 502. The straight rod 503 is hidden inside the connecting plate 501, and the ends of several connecting plates 501 are jointly sleeved on a connecting rod 504. The connecting rod 504 passes through the ends of several straight rods 503. An electric push rod 505 is fixedly installed on the top of the scaffolding body 1, and the output end of the electric push rod 505 is connected to the end of the connecting rod 504.
[0049] In this embodiment, in rainy and snowy weather, the top of the first vent film 403 is covered with accumulated rain and snow, and the first vent film 403 cannot be rolled up directly. At this time, the operator controls the electric push rod 505 to operate, and the output end of the electric push rod 505 extends outward and pushes the straight rod 503 through the connecting rod 504, causing the straight rod 503 to move along the inside of the connecting plate 501, and at the same time pushes the steel plate 502, causing the straight rod 503 to rotate around the connecting rod 504, and the steel plate 502 to rotate around the inside of the connecting plate 501. At the same time, the steel plate 502 bulges outward to lift the first vent film 403, and at the same time, push down the rain and snow accumulated on the top of the first vent film 403. The rain and snow will slide down along the surface of the shed film 2, and at the same time, an opening will be formed between the straight rod 503 and the deformed steel plate 502 and the connecting plate 501. The specific state is as follows: Fig.10 As shown; thereby ventilating the interior of the scaffolding body 1; wherein, the length of the connecting plate 501 is greater than the upper air outlet 3, so that the length of the first air outlet membrane 403 laid on the top of the connecting plate 501 under normal conditions is greater than the upper air outlet 3, ensuring that when the first air outlet membrane 403 is raised, it can still block the top of the upper air outlet 3.
[0050] Furthermore, a slot 506 is fixedly installed at the end of the connecting plate 501, and the end of the first air outlet membrane 403 is pressed and engaged with the inside of the slot 506 by a retaining spring 507, and the end of the first air outlet membrane 403 is fixed by the quick installation of the retaining spring 507 and the slot 506.
[0051] In the above scheme, in order to maintain the temperature inside the shelf body 1 in winter, the specific operation is as follows.
[0052] Reference Figure 1 to Figure 2 , Figure 5 In a preferred embodiment, a heat preservation mechanism 6 is provided on the top of the scaffold body 1;
[0053] The heat preservation mechanism 6 includes a second type telescopic rod 601 rotatably mounted on the side of the scaffolding body 1 , a third film rolling device 602 is sleeved on the top of the second type telescopic rod 601 , a quilt 603 is rolled up on the top of the scaffolding body 1 , and the quilt 603 is sleeved on the outer side of the output end of the third film rolling device 602 .
[0054] In this embodiment: in severe cold weather in winter, the operator starts the third film roll 602, causing the third film roll 602 to unwind along the top of the scaffolding body 1, unfolding the rolled quilt 603 and covering the top of the scaffolding body 1. At the same time, the third film roll 602 itself will move along the top of the scaffolding body 1, and the second type of telescopic rod 601 will adaptively extend and retract to match the movement of the third film roll 602.
[0055] Reference Figure 1 and Figure 4 In a preferred embodiment, a thermal insulation layer 7 is provided on one side of the bottom of the scaffolding body 1, an anti-aging thermal insulation layer 8 is fixed inside the scaffolding body 1, a reflective heat insulation layer 9 is provided on one side of the anti-aging thermal insulation layer 8 close to the thermal insulation layer 7, a hollow air layer 10 is formed between the reflective heat insulation layer 9 and the thermal insulation layer 7, and a nano-metal film heat absorption coating heat collecting plate 11 is installed on the other side of the anti-aging thermal insulation layer 8.
[0056] In this embodiment: the side of the scaffolding body 1 adopts a heat preservation and cold-proof layer 7 and a reflective heat-insulating layer 9, so that a hollow air layer 10 is formed between the heat preservation and cold-proof layer 7 and the reflective heat-insulating layer 9. Through this double-layer interception, the heat loss is greatly reduced, and the heat preservation effect of the hollow air layer 10 is greatly improved compared with the traditional single-layer wall. At the same time, the anti-aging heat preservation layer 8 can extend the service life of the reflective heat-insulating layer 9, and the nano-metal film heat-absorbing coating heat-collecting plate 11 is matched with an external nano-metal film, a heat-absorbing coating heat-collecting plate, a circulation pipeline, a heat storage tank, a floor heating pipeline, an automatic temperature control system, etc., to form an active heat storage and release system; wherein the heat-collecting plate is made of aluminum alloy, and the surface is sprayed with a nano-metal film heat-absorbing coating, with a width of 1m and a height of 1.8m. The whole system adopts a closed same-path circulation method to ensure uniform water flow;
[0057] The average heat collection power of the active heat storage and release system is 105-183W / m2, and the heat collection per unit area is 2.6-4.6MJ / m2, which can increase the nighttime temperature in the greenhouse by more than 8°C.
[0058] Among them, it should be supplemented that: the heat preservation and cold-proof layer 7 includes two layers of woven cloth 701 fixed to the outside of the scaffold body 1, the inside of the woven cloth 701 is mixed with pearl cotton 702 and heat preservation felt 704, and composite space cotton 703 is fixed between the pearl cotton 702 (the woven cloth 701 is 120g, the pearl cotton 702 is 3mm, and the heat preservation felt 704 is 500g);
[0059] The reflective insulation layer 9 includes two layers of pure aluminum foil 901, two layers of vacuum polyethylene bubble layers 902 are sandwiched inside the pure aluminum foil 901, and the vacuum polyethylene bubble layers 902 are filled with polyethylene adhesive layers 903; and the anti-aging thermal insulation layer 8 is mainly composed of thermal insulation and anti-aging felt, which has the advantages of strong corrosion resistance, good drainage performance, high tensile strength, long anti-aging time and good thermal insulation performance.
[0060] Furthermore, it is supplemented that: an internal thermal insulation and sunshade layer 12 is suspended inside the scaffolding body 1, and an aluminum foil reflective insulation skirt 13 is installed on the outer side of the bottom of the scaffolding body 1, and the aluminum foil reflective insulation skirt 13 is distributed below the upper air outlet 3. The internal thermal insulation and sunshade layer 12 and the aluminum foil reflective insulation skirt 13 are used to further maintain the thermal insulation efficiency inside the scaffolding body 1.
[0061] Working principle: When in use, the first film rolling device 402 and the second film rolling device 405 are started and rolled up along the outer side of the upper air outlet 3. While the first film rolling device 402 rolls up the first air outlet film 403, it moves along the top of the scaffolding body 1. At the same time, the telescopic rod 401 will be adaptively extended and retracted. While the second film rolling device 405 rolls up the second air outlet film 406, it moves vertically along the outer side of the sliding rod 404, thereby exposing the two upper air outlets 3 to ventilate the interior of the scaffolding body 1.
[0062] In rainy and snowy weather, the top of the first vent film 403 is covered with accumulated rain and snow, and the first vent film 403 cannot be rolled up directly. At this time, the operator controls the electric push rod 505 to operate. The output end of the electric push rod 505 extends outward and pushes the straight rod 503 through the connecting rod 504, causing the straight rod 503 to move along the inside of the connecting plate 501, and at the same time pushes the steel plate 502, causing the straight rod 503 to rotate around the connecting rod 504, and the steel plate 502 to rotate around the inside of the connecting plate 501. At the same time, the steel plate 502 bulges outward to lift the first vent film 403, and at the same time, push down the rain and snow accumulated on the top of the first vent film 403. The rain and snow will slide down along the surface of the shed film 2, and at the same time, an opening will be formed between the straight rod 503 and the deformed steel plate 502 and the connecting plate 501. The specific state is as follows Fig.10 As shown; thereby ensuring that rain and snow cannot enter the interior of the scaffolding body 1 through the upper wind port 3, and facilitating ventilation of the interior of the scaffolding body 1. In windy weather, rain and snow will blow into the interior of the scaffolding body 1 from the side openings. In this case, ventilation cannot be opened.
