Description

Technical Field

[0001] This invention relates to the field of agricultural greenhouse technology, specifically to a power-generating vacuum glass greenhouse for seed and seedling cultivation. Background Technology

[0002] Greenhouses are important facilities for seed and seedling cultivation. They provide a suitable growing environment for seedlings and avoid the impact of harsh external climate on their growth. In the process of seed and seedling cultivation, root temperature plays a crucial role in the growth quality of seedlings. Suitable soil temperature can promote root development and improve the survival rate and stress resistance of seedlings.

[0003] For example, Chinese patent CN120836335A discloses an intelligent vacuum glass thermoelectric greenhouse, including a vacuum glass panel, a collection system, a circulation system, and a control system. The vacuum glass panel is arranged on the top and around the mounting frame. The collection system is connected to the vacuum glass panel on the top of the mounting frame. The circulation system is connected to the collection system. The control system is electrically connected to the circulation system. By integrating a perovskite solar cell layer, a Low-E film, and a microfluidic channel into the vacuum glass panel, it can accumulate solar energy in winter and efficiently provide unidirectional heating to the greenhouse. In summer, when the temperature inside the greenhouse exceeds a threshold, it can collect rainwater and circulate it in the microfluidic channel for active cooling, while converting direct sunlight in summer into soft scattering to ensure the seedling cultivation environment. This solves the problems of high energy consumption for heating and cooling in vacuum glass greenhouses in summer and winter, and the inability of traditional solar photovoltaic panels to effectively maintain the temperature control system.

[0004] Seed and seedling cultivation requires maintaining a higher temperature at the root and a lower temperature at the top to promote root growth. However, the aforementioned patents and existing technologies cannot precisely control the temperature difference between the root soil and the seedlings, thus affecting the survival rate of the seeds and seedlings. Therefore, we propose a power-generating vacuum glass greenhouse for seed and seedling cultivation. Summary of the Invention

[0005] This invention provides a power-generating vacuum glass greenhouse for seed and seedling cultivation. This power-generating vacuum glass greenhouse for seed and seedling cultivation can solve the problem mentioned in the background art that seed and seedling cultivation requires maintaining a high temperature at the root and a low temperature at the top to promote seedling root growth. The above-mentioned patents and existing technologies cannot accurately control the temperature difference between the root soil and the seedling, thus affecting the survival rate of the seed and seedling.

[0006] To achieve the above objectives, this solution provides a power-generating and heat-generating vacuum glass greenhouse for seed and seedling cultivation, comprising a strip foundation, a greenhouse truss for installing vacuum glass on the strip foundation, a power generation component and a heat-generating component on the greenhouse truss, the power generation component including a photovoltaic panel, the photovoltaic panel being installed on the top of the greenhouse truss, and a battery module being installed inside the greenhouse truss, the battery module being electrically connected to the photovoltaic panel; The heating component includes a heater, which is installed inside the greenhouse truss. A heating pipe is buried under the soil inside the greenhouse truss. The heating pipe is located adjacent to the seedling area, and the water inlet of the heating pipe is connected to the hot water end of the heater, while the water outlet of the heating pipe is connected to the cold water end of the heater. An insulating cotton felt is laid on top of the heating pipe, and the insulating cotton felt is movable.

[0007] Optionally, the interior floor of the greenhouse truss is made of cement, and a pair of seedling troughs are provided on the cement floor. A geothermal trough is provided between the pair of seedling troughs, and the heating pipe is buried in the soil layer of the geothermal trough.

[0008] Optionally, a pair of vertical plates are provided inside the geothermal trough, and several support rods are connected between the pair of vertical plates. The thermal insulation felt is laid on the support rods, and the distance between the support rods and the soil below is not less than 10cm. One end of the thermal insulation felt is detachably connected to the vertical plate by bolts, and the other end of the thermal insulation felt has a through hole. A fixing ring is installed at the through hole, and the fixing ring is slidably installed on the support rod.

[0009] Optionally, a push plate is slidably mounted on the support rod, the push plate is disposed adjacent to the fixing ring, and one end of the thermal insulation felt near the push plate is connected to the push plate by a flexible rope; after the push plate slides on the support rod, the thermal insulation felt is folded or unfolded.

[0010] Optionally, a temperature sensor is installed in the seedling trough, and the temperature sensor is located adjacent to the geothermal trough; a motor for driving the push plate to move is installed in the geothermal trough, a drive gear is provided on the output shaft of the motor, a horizontal rack is installed at the bottom of the push plate, the horizontal rack meshes with the drive gear, the motor is set as a stepper motor, and the heat insulation cotton felt is folded or unfolded when the motor rotates forward and reverse.

[0011] Optionally, the geothermal tank is provided with a sealing box for isolating the soil, one end of the horizontal rack is located inside the sealing box, and the other end of the horizontal rack is provided with a horizontal rod, which is slidably inserted into the sealing box.

[0012] Optionally, a limiting sleeve is fixedly fitted on the support rod near the greenhouse glass door. The outer diameter of the limiting sleeve is larger than the inner diameter of the fixing ring. After the fixing ring abuts against the limiting sleeve, the insulation cotton felt near the greenhouse glass door is in a semi-folded state.

[0013] Optionally, arc-shaped plates are installed at both ends of the push plate, and the ends of the arc-shaped plates are rounded. Furthermore, the distance between adjacent horizontal bars is less than the width of the thermal insulation felt within that distance.

Install heating pipes in the soil layer near the seedling trough to provide targeted insulation for the soil layer, so that the soil root temperature is higher than the upper air temperature, which is conducive to the growth of seedling roots. When the temperature at the edge of the seedling trough reaches the warning value, the motor will start automatically and fold the insulation cotton felt to accelerate the heat loss of the geothermal trough, thereby responding quickly to abnormal temperature conditions at the seedling end and ensuring the normal growth of seedlings. 2. After the insulation cotton felt is folded, the fixing rings at both ends of the insulation cotton felt abut against the limiting sleeve, ensuring that the insulation cotton felt near the greenhouse glass door will not be fully opened, preventing the soil temperature near the glass door from being too low, and making the soil temperature along the length of the seedling trough more uniform.

Detailed Implementation

[0027] To make the aforementioned objectives, features, and advantages of this solution more apparent and understandable, the specific embodiments of this solution are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this solution. However, this solution can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this solution. Therefore, this solution is not limited to the specific embodiments disclosed below.

[0028] In the description of this solution, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this solution and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this solution. The terms "first" and "second" are used to distinguish one element from another and do not have sequential or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings indicate the same or similar elements, which will not be repeated here.

[0029] In this solution, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this solution based on the specific circumstances.

[0030] According to some embodiments of this solution, a power-generating and heat-generating vacuum glass greenhouse for seed and seedling cultivation is provided, for reference. Figures 1 to 8 As shown, the power generation and heating vacuum glass greenhouse for seed and seedling cultivation includes a strip foundation 101, on which a greenhouse truss 102 for installing vacuum glass is provided. The greenhouse truss 102 uses vacuum glass as the enclosure structure, and power generation components and heating components are provided on the greenhouse truss 102.

[0031] Specifically, the strip foundation 101 is a long strip of continuously cast reinforced concrete or brick masonry foundation, which is arranged like a strip along the bottom of the wall and columns. Unlike a single independent foundation, the interior floor of the greenhouse truss 102 is set as a cement floor, and a pair of seedling troughs 103 are opened on the cement floor. A geothermal trough 104 is set between the pair of seedling troughs 103.

[0032] The power generation component includes a photovoltaic panel 201, which is installed on the top of the greenhouse truss 102. A battery module 202 is installed inside the greenhouse truss 102 and is electrically connected to the photovoltaic panel 201.

[0033] The heating component includes a heater 301, which is installed inside the greenhouse truss 102. A steel plate 302 for personnel to walk on is hinged above the geothermal trough 104. The steel plate 302 is a stainless steel plate with several grooves. A heating pipe 303 is buried under the soil inside the greenhouse truss 102. The heating pipe 303 is located near the seedling area, and the water inlet of the heating pipe 303 is connected to the hot water end of the heater 301, and the water outlet of the heating pipe 303 is connected to the cold water end of the heater 301.

[0034] The heater 301 heats the water and circulates it through the heating pipe 303, heating the soil around the heating pipe 303. Since the heating pipe 303 is located near the seedling area, it can target the soil in the root area of ​​the seedlings, making the soil temperature at the root area higher than the upper air temperature, creating a warm root and cool head growth environment, which is conducive to promoting the downward growth of the seedling roots, enhancing root vitality and absorption capacity, and improving the quality of seedling cultivation.

[0035] In this way, by precisely heating the seedling root area through the heating pipe 303, combined with the heat insulation performance of the vacuum glass greenhouse truss 102, the temperature gradient between the roots and the upper part of the greenhouse can be effectively maintained, solving the problem of the inability to precisely control the temperature difference between the roots and the soil of seeds and seedlings in the existing technology.

[0036] Heating pipes 303 are buried in the soil layer of geothermal trough 104. Seedling troughs 103 are used to place seedling cultivation substrate and seedlings. Geothermal trough 104 is located between a pair of seedling troughs 103, so that the heat generated by heating pipes 303 can be conducted to both seedling troughs 103 simultaneously, improving heat utilization. Heating pipes 303 are laid in a serpentine or reciprocating pattern at the bottom of geothermal trough 104, buried at a depth of 10-30cm, with adjacent pipe sections spaced apart to ensure that the soil on both sides of seedling trough 103 is heated evenly, so that the seedlings in both seedling troughs 103 can obtain a suitable geothermal environment.

[0037] A pair of vertical plates 313 are installed inside the geothermal trough 104, and several support rods 305 are connected between the two vertical plates 313. Insulating cotton felt 304 is laid above the heating pipe 303, and the insulating cotton felt 304 is movable. The insulating cotton felt 304 is laid on the support rods 305, with a distance of not less than 10cm between the support rods 305 and the soil below. This covers and insulates the soil in the geothermal trough 104, reducing heat loss and improving heating efficiency. Maintaining a distance of not less than 10cm between the support rods 305 and the soil below allows for heat conduction between the heating pipe 303 and the soil, and also prevents the insulating cotton felt 304 from directly contacting the soil and becoming damp and damaged.

[0038] Angle steel 306 is fixedly installed inside the geothermal trough 104. When the steel plate 302 is in a horizontal state, its edge is supported on the angle steel 306. The steel plate 302 covers the geothermal trough 104, allowing workers to walk on it for convenient daily management of the seedlings in the seedling trough 103. The slots on the steel plate 302 reduce its weight and facilitate flipping, while also allowing heat from the geothermal trough 104 to be conducted upwards without affecting heat transfer to the seedling trough 103. The stainless steel material has good corrosion resistance and can be used for a long time in the humid environment of the greenhouse. When maintenance is required on the heating pipe 303 or the transmission mechanism inside the geothermal trough 104, the steel plate 302 can be flipped upwards for easy maintenance.

[0039] One end of the thermal insulation felt 304 is detachably connected to the vertical plate 313 by bolts, and the other end of the thermal insulation felt 304 has a through hole. A fixing ring 316 is installed at the through hole. The fixing ring 316 is slidably installed on the support rod 305. One end of the thermal insulation felt 304 is fixed, and the other end slides on the support rod 305 through the fixing ring 316, so that the thermal insulation felt 304 can switch between an unfolded covering state and a folded heat dissipation state. When the thermal insulation felt 304 is unfolded, it covers the geothermal tank 104 for heat preservation. When heat dissipation and cooling are required, the thermal insulation felt 304 is folded along the support rod 305, so that the heat in the geothermal tank 104 is dissipated outward more quickly.

[0040] In addition, a sealing box 307 for isolating the soil is provided inside the geothermal tank 104. A push plate 312 is slidably mounted on the support rod 305. The push plate 312 is located near the fixing ring 316. One end of the insulation felt 304 near the push plate 312 is connected to the push plate 312 by a flexible rope. When the push plate 312 slides on the support rod 305, it pulls the end of the insulation felt 304 through the flexible rope, causing the insulation felt 304 to fold or unfold.

[0041] Specifically, the insulation cotton felt 304 has fold lines spaced along its length, and flexible ropes are connected to the fold ends. When the push plate 312 moves, the flexible ropes pull the fold lines in sequence to form continuous folds, which increases the exposed area of ​​the geothermal trough 104 and accelerates heat dissipation. When the push plate 312 slides towards the vertical plate 313, the insulation cotton felt 304 gradually unfolds under its own gravity and elastic recovery force, and covers the geothermal trough 104 again for insulation.

[0042] A temperature sensor is installed inside the seedling trough 103, adjacent to the geothermal tank 104, to monitor the soil temperature on the side of the seedling trough 103 closest to the geothermal tank 104 in real time. A horizontal rack 308 is installed at the bottom of the push plate 312, and a motor 310 is installed inside the geothermal tank 104 to drive the push plate 312. A drive gear 309 is installed on the output shaft of the motor 310, and the horizontal rack 308 meshes with the drive gear 309. Both the horizontal rack 308 and the drive gear 309 are made of stainless steel. The motor 310 is a stepper motor. When the motor 310 rotates forward and backward, the insulation felt 304 is folded or unfolded.

[0043] Thus, when the temperature sensor detects that the soil temperature at the edge of the seedling trough 103 reaches the preset warning value, it indicates that the temperature in the root area of ​​the seedling is too high, which may cause heat damage to the seedling roots. At this time, the motor 310 automatically starts, and the forward rotation of the motor 310 drives the drive gear 309 to rotate. The drive gear 309 drives the push plate 312 to move through the horizontal rack 308. The push plate 312 pulls the heat insulation felt 304 through the flexible rope to fold, so that the heat in the geothermal trough 104 can be dissipated outward at an accelerated rate, reducing the soil temperature at the seedling roots. This allows for a rapid response to abnormal temperature conditions at the seedling end, preventing damage to the seedlings due to excessively high root temperatures and ensuring normal seedling growth. When the temperature returns to a suitable range, the motor 310 reverses, the drive gear 309 drives the push plate 312 to reset, and the heat insulation felt 304 unfolds again to cover the geothermal trough 104 for heat preservation. The use of a stepper motor can precisely control the displacement of the push plate 312, thereby precisely controlling the degree of folding of the heat insulation felt 304 and achieving fine adjustment of heat dissipation.

[0044] One end of the horizontal rack 308 is located inside the sealing box 307, and the other end of the horizontal rack 308 is provided with a horizontal rod 311. The horizontal rod 311 is slidably inserted into the sealing box 307. The sealing box 307 isolates the end of the horizontal rack 308 from the soil, preventing water and impurities in the soil from entering the meshing part, avoiding gear rack failure due to corrosion or jamming, and extending the service life of the transmission mechanism. The horizontal rod 311 is slidably inserted into the sealing box 307 to provide guidance and support for the movement of the horizontal rack 308, ensuring the smooth movement of the push plate 312.

[0045] In some implementations of this solution, reference is made to Figure 5 As shown, a limiting sleeve 314 is fixedly sleeved on the support rod 305 near the greenhouse glass door. The outer diameter of the limiting sleeve 314 is larger than the inner diameter of the fixing ring 316. After the fixing ring 316 abuts against the limiting sleeve 314, the heat insulation cotton felt 304 near the greenhouse glass door is in a semi-folded state.

[0046] Because the insulation performance at the glass door is relatively poor, heat is easily lost from the glass door. If the insulation cotton felt 304 is fully unfolded or fully folded near the glass door, the soil temperature near the glass door will be too different from other areas. By setting the limiting sleeve 314, when the insulation cotton felt 304 is folded, the fixing ring 316 stops moving after contacting the limiting sleeve 314, so that the insulation cotton felt 304 near the greenhouse glass door is only in a half-folded state. This ensures a certain heat dissipation effect and prevents the soil temperature near the glass door from being too low. It also makes the soil temperature along the length of the seedling trough 103 more uniform and avoids uneven growth of seedlings due to excessive local temperature differences.

[0047] Arc-shaped plates 315 are installed at both ends of the push plate 312. The ends of the arc-shaped plates 315 are rounded. The arc-shaped plates 315 come into contact with the insulation cotton felt 304 during the movement of the push plate 312. The rounded corners can prevent the sharp edges of the arc-shaped plates 315 from scratching or tearing the insulation cotton felt 304 when pushing it to fold, thus protecting the integrity of the insulation cotton felt 304 and extending its service life.

[0048] The distance between two adjacent horizontal bars 311 is less than the width of the insulation felt 304 within that distance. With this setting, when the insulation felt 304 is folded, it forms a folded shape between the adjacent horizontal bars 311, ensuring the smoothness and reliability of the folding and unfolding process of the insulation felt 304.

[0049] A ventilation system is also installed on the greenhouse truss 102, which includes several matrix fans 401, fixedly mounted on the greenhouse truss 102. Photovoltaic panels 201 convert solar energy into electrical energy and store it in battery modules 202, providing power to electrical equipment such as heaters 301, motors 310, and matrix fans 401 within the greenhouse. This enables the greenhouse to have its own power supply, reducing dependence on the external power grid and saving energy costs.

[0050] After the insulation cotton felt 304 is folded, the matrix fan 401 starts to accelerate the air circulation inside the greenhouse truss 102. When the insulation cotton felt 304 is folded to dissipate heat, the heat in the geothermal trough 104 is dissipated outward at an accelerated rate. At this time, the matrix fan 401 starts to accelerate the air circulation inside the greenhouse, making the heat dissipation more uniform and faster. At the same time, it promotes the uniform distribution of temperature and humidity inside the greenhouse, providing a more suitable growth environment for the seedlings.

[0051] Through the above technical solution, the photovoltaic panel 201 converts solar energy into electrical energy and stores it in the battery module 202 to power various electrical devices in the greenhouse when the vacuum glass greenhouse for seed and seedling cultivation is in use. The heater 301 circulates hot water through the heating pipe 303 to the soil layer of the geothermal trough 104 to heat the soil near the seedling trough 103, so that the soil temperature at the seedling roots is higher than the upper air temperature, forming a temperature gradient that is conducive to root growth. The heat insulation cotton felt 304 covers the geothermal trough 104 to keep it warm and reduce heat loss. When the temperature sensor detects that the soil temperature at the edge of the seedling trough 103 has reached the preset warning value, the motor 310 starts automatically. It drives the push plate 312 to move through the drive gear 309 and the horizontal rack 308. The push plate 312 pulls the heat insulation felt 304 through the flexible rope to fold it, thereby accelerating the heat loss of the geothermal trough 104. This allows for a rapid response to abnormal temperature conditions at the seedling end, ensuring the normal growth of the seedlings.

[0052] It should be noted that in the prior art, the signal output terminal of the temperature sensor is electrically connected to the signal input terminal of the controller, and the controller is electrically connected to the motor 310, heater 301, and matrix fan 401. Therefore, in specific implementation, the temperature sensor monitors the soil temperature in the seedling trough 103 in real time and transmits the data to the controller. The controller automatically determines whether the motor 310 needs to be started for heat dissipation based on the preset temperature value, thereby realizing the automated and precise control of the greenhouse soil temperature. The specific models and connection methods of the controller and temperature sensor are mature technologies well known to those skilled in the art and will not be elaborated here.

[0053] The preferred embodiments of this solution have been described in detail above with reference to the accompanying drawings. However, this solution is not limited to the specific details in the above embodiments. Within the scope of the technical concept of this solution, various simple modifications can be made to the technical solution, and these simple modifications all fall within the protection scope of this solution.

[0054] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this solution will not describe the various possible combinations separately.

[0055] Furthermore, various implementations of this solution can be combined in any way, as long as they do not violate the spirit of this solution, they should also be regarded as the content disclosed in this solution.
