Description

Technical Field

[0001] This invention relates to the field of greenhouse technology, specifically to a heat circulation ventilation wall for seedling greenhouses. Background Technology

[0002] As a core facility ensuring high-quality seedling cultivation, the thermal performance and ventilation control capabilities of the seedling greenhouse walls directly affect the stability of the microenvironment, including temperature and light, thus determining the growth quality and survival rate of the seedlings. With the advancement of agricultural modernization, the demand for refined and zoned control of temperature and humidity in seedling cultivation is increasing, but existing greenhouse walls still have many technical defects.

[0003] Traditional greenhouse walls often employ a monolithic structure or a single-material splicing design, resulting in complex assembly and disassembly processes. This makes it difficult to flexibly combine structures according to adjustments in seedling planting zones, and partial damage necessitates complete dismantling and reconstruction, leading to high maintenance costs. Regarding heat storage and temperature control, existing wall structures are mostly single water tanks or insulation layers, resulting in low heat exchange efficiency and uneven heat distribution and excessive temperature fluctuations, failing to meet the temperature-sensitive growth characteristics of seedlings. Furthermore, most walls only focus on insulation or cooling for a single season, requiring additional heating and cooling equipment for year-round adaptability, leading to high energy consumption and lag in control. In terms of ventilation system design, existing technologies mostly use monolithic air supply structures, lacking targeted angle adjustment and zoned circulation mechanisms. Direct cold air blowing or uneven ventilation can easily cause inconsistent seedling growth. Moreover, ventilation and heat storage systems often operate independently, failing to achieve coordinated control, resulting in low heat utilization efficiency and difficulty in meeting the differentiated temperature, humidity, and ventilation requirements of seedlings at different growth stages.

[0004] Therefore, we propose a heat circulation ventilation wall for seedling greenhouses. Summary of the Invention

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0033] Please see Figures 1 to 10 As shown, a heat circulation ventilation wall for a seedling greenhouse includes several ventilation wall modules 1. The several ventilation wall modules 1 are spliced ​​together to form the heat circulation ventilation wall of the seedling greenhouse. The top of the heat circulation ventilation wall is covered with a greenhouse film. Hot water heaters and cold water tanks are set on both sides of the heat circulation ventilation wall. The interiors of the hot water heaters and cold water tanks are connected to the interior of the ventilation wall modules 1 through circulating water pumps.

[0034] It should be noted that when carrying out heat circulation ventilation inside the seedling greenhouse, hot water and cold water are selectively introduced into the ventilation wall module 1 to carry out heat circulation ventilation treatment for the seedlings inside the greenhouse. Depending on the hot water and cold water introduced, the greenhouse can be heated and cooled. The ventilation temperature can be controlled by using hot water and cold water in different areas of the seedlings.

[0035] Specifically, an outer protective plate 2 is fixed to the outside of the ventilation wall module 1 by bolts, and the outer protective plate 2 is made of high light transmittance PC board; a reflective groove 7 is provided inside the ventilation wall module 1 on the side near the outer protective plate 2, and several reflective strips 8 are rotatably arranged inside the reflective groove 7. The several reflective strips 8 are arranged horizontally and vertically inside the reflective groove 7, and the two ends of the reflective strips 8 are rotatably connected to the two sides inside the reflective groove 7 respectively; a transmission gear 9 is fixedly provided at one end of each of the several reflective strips 8, and the surfaces of the several transmission gears 9 are connected by a synchronous belt 10. A synchronous motor 11 is also fixedly provided on one side inside the reflective groove 7, and one end of the output shaft of the synchronous motor 11 is fixedly connected to one end of the uppermost reflective strip 8 through a coupling.

[0036] It should be noted that the reflective strip 8 is made of aluminum foil composite board with an anti-oxidation coating on the surface. The output shaft of the synchronous motor 11 controls the angle deflection of one end of the uppermost reflective strip 8. Through the transmission gears 9 set at one end of several reflective strips 8 and the synchronous belt 10, several reflective strips 8 are deflected synchronously, thereby realizing the light focusing and light blocking control of the wall. In winter, by adjusting the reflective strip 8 to the light focusing angle, sunlight is reflected to the heat storage unit inside the wall. In summer, by adjusting the reflective strip 8 to the light blocking angle, direct sunlight on the wall is blocked, thereby reducing the heat absorption of the wall.

[0037] Furthermore, a heat storage mounting bracket 12 is fixedly installed inside the ventilation wall module 1 and on the inner side of the reflective groove 7. The heat storage mounting bracket 12 has several mounting grooves 15 inside, and heat storage blocks 13 are installed inside each of the mounting grooves 15. The inner and outer sides of the heat storage blocks 13 penetrate the interior of the mounting grooves 15. The heat storage blocks 13 are honeycomb-shaped clay heat storage blocks, and heat exchange holes are provided inside the clay heat storage blocks. A thin water pipe 14 is installed inside the heat storage mounting bracket 12 and penetrates the interior of the heat storage blocks 13. Several heat conduction grooves 17 are provided on the back of the heat storage mounting bracket 12, and the surface of the thin water pipe 14 passes through the interior of the heat conduction grooves 17. Several heat conduction fins 16 are provided on the surface of the thin water pipe 14 and inside the heat conduction grooves 17. The heat conduction fins 16 are arranged horizontally and vertically inside the heat conduction grooves 17.

[0038] Specifically, one end of the thin water pipe 14 extends to one side of the top of the ventilation wall module 1, and a water guide hole is provided on one side of the bottom of the ventilation wall module 1 to cooperate with the thin water pipe 14. The other end of the thin water pipe 14 is connected to the inside of the water guide hole. A water guide pipe 28 is provided inside the water guide hole on one side of the bottom of the lowest ventilation wall module 1. The inside of the water guide pipe 28 is connected to the inside of the hot water heater and the cold water tank through a three-way valve. The connection between the upper and lower adjacent ventilation wall modules 1 is achieved through the connection between the thin water pipe 14 and the inside of the water guide hole, so as to realize the internal connection of the thin water pipe 14 inside the upper and lower ventilation wall modules 1.

[0039] It should be noted that multiple sets of thin water pipes 14 are installed inside the heat storage mounting frame 12. These thin water pipes 14 pass through the honeycomb holes inside the heat storage block 13 for heat exchange. The thin water pipes 14 are made of copper, which has a high thermal conductivity. Several reflective strips 8 concentrate sunlight onto the outside of the heat storage block 13. The heat storage block 13 absorbs and stores the concentrated heat, and the absorbed heat is exchanged through the thin water pipes 14 to achieve heat preservation and heating of the water inside the thin water pipes 14. Finally, several heat-conducting fins 16 conduct the heat out of the thin water pipes 14, and together with the ventilation structure, the heat is blown into the interior of the seedling greenhouse, achieving heat circulation and ventilation of the seedling greenhouse. In winter, hot water is introduced into the thin water pipes 14, and the heat storage block 13, which has absorbed heat, insulates the thin water pipes 14, thereby effectively keeping the interior of the seedling greenhouse warm. Example 2

[0040] Specifically, axial flow fan 18 and axial flow fan 2 19 are fixedly installed on the left and right sides inside the ventilation wall module 1, respectively. Both axial flow fan 18 and axial flow fan 2 19 are reversible axial flow fans. By controlling the impeller blades of the reversible axial flow fans to rotate forward and backward, the air inlet and outlet directions of axial flow fans 18 and 19 are changed, while maintaining a stable air volume and air pressure. An air guide is provided at the air inlet end of axial flow fan 18. The air inlet 20 is equipped with an automatic control valve inside; one side of the air inlet 20 extends to the outside of the ventilation wall module 1, and an air inlet filter is installed inside the air inlet 20; the air outlet of the axial flow fan 18 faces the side of the axial flow fan 29, and the air inlet of the axial flow fan 29 faces the side of the axial flow fan 18; the air outlet of the axial flow fan 29 is equipped with an air guide frame 21, and one end of the air guide frame 21 is equipped with a ventilation mounting bracket 4.

[0041] Furthermore, an air duct 25 is provided on one side of the top of the ventilation wall module 1, and the interior of the air duct 25 is connected to the interior of the air inlet of the axial flow fan 18. An air duct 26 that cooperates with the air duct 25 is provided on one side of the bottom of the ventilation wall module 1.

[0042] Furthermore, an inner mounting plate 3 is fixedly installed on the inner side of the ventilation wall module 1, and a ventilation mounting bracket 4 is fixedly installed inside the inner mounting plate 3. The ventilation mounting bracket 4 has several movable slots 6 inside, and movable air blowing brackets 5 are rotatably installed inside each of the several movable slots 6. One side of each of the several movable air blowing brackets 5 is connected to the interior of the air guide frame 21.

[0043] Furthermore, a transmission gear 22 is fixedly installed at one end of each of the several movable air blowing frames 5, and the surfaces of the several transmission gears 22 are connected by a synchronous belt 23. A synchronous motor 24 is fixedly installed on one side inside the mounting inner plate 3, and one end of the output shaft of the synchronous motor 24 is fixedly connected to one end of the uppermost movable air blowing frame 5 through a coupling.

[0044] It should be noted that during the heat circulation ventilation inside the seedling greenhouse, external air is introduced into the axial flow fan 18 through the air inlet 20. The axial flow fan 18 blows the external air over the surface of several heat-conducting fins 16, preheating the air with the heat conducted by the heat-conducting fins 16. The preheated air is then introduced into several movable air blowing frames 5 by the axial flow fan 2 19. The blowing angle is adjusted according to the height of the seedlings. The output shaft of the synchronous motor 2 24 controls the rotation of the movable air blowing frames 5 to achieve... The blowing angle of several movable air blowers 5 can be adjusted to carry out heat circulation ventilation operation for seedlings in different growth stages; and a temperature sensor is installed on the inner side of each ventilation wall module 1 to monitor the temperature of the seedling greenhouse on one side of each ventilation wall module 1. For areas with excessively high temperatures, the air is drawn from the high-temperature area and sent to the low-temperature area by the air guide interface 25 and air guide pipe 26 connected between adjacent ventilation wall modules 1, thereby realizing heat circulation ventilation treatment inside the seedling greenhouse. Example 3

[0045] Specifically, the ventilation wall module 1 is provided with locking connection holes 37 on all four sides, and the ventilation wall module 1 is provided with assembly connection holes 29 on both the inner and outer sides; the locking connection holes 37 on both sides of the ventilation wall module 1 are provided with horizontal assembly locking blocks 30, and the locking connection holes 37 on the upper and lower sides of the ventilation wall module 1 are provided with vertical assembly locking blocks 31. The two ends of the horizontal assembly locking blocks 30 are provided with locking protrusions 32, and the upper and lower ends of the vertical assembly locking blocks 31 are provided with locking recesses 33 that cooperate with the locking protrusions 32. The locking protrusions 32 and locking recesses 33 are provided with locking threaded holes 34. The internal threads of the assembly connection holes 29 are provided with locking bolts 35, and one end of the locking bolts 35 passes through the interior of the two locking threaded holes 34 and connects with the internal threads of the ventilation wall module 1.

[0046] Furthermore, each of the ventilation wall modules 1 has an assembly sealing groove 36 on its outer periphery, and a sealing gasket is provided between two adjacent ventilation wall modules 1. The two sides of the sealing gasket are located inside the two adjacent assembly sealing grooves 36 respectively. The sealing gasket is used to seal the adjacent ventilation wall modules 1 to ensure the airtightness of the inside of the seedling greenhouse.

[0047] It should be noted that during the assembly of the ventilation wall module 1, the ventilation wall modules 1 are first stacked vertically. Vertical assembly locking blocks 31 are inserted into the locking connection holes 37 between the upper and lower ventilation wall modules 1. Simultaneously, sealing gaskets are placed between adjacent upper and lower assembly sealing grooves 36 to complete the vertical stacking assembly of the ventilation wall modules 1. After assembling multiple sets of vertical ventilation wall modules 1, these multiple sets of vertical ventilation wall modules 1 are finally horizontally assembled, connecting adjacent sets of ventilation wall modules. The horizontal assembly locking block 30 is connected to the vertical assembly locking block 31 by inserting the timing belt 23 at one end of the horizontal assembly locking block 30 into the locking connection hole 37, so that the locking protrusion 32 is inserted into the locking recess 33 at one end of the vertical assembly locking block 31. Finally, the locking bolt 35 is inserted into the assembly connection hole 29 to connect the horizontal assembly locking block 30, the vertical assembly locking block 31 and the ventilation wall module 1 by thread, so as to complete the splicing and assembly of the ventilation wall module 1 and form the wall of the seedling greenhouse. Example 4

[0048] Specifically, this embodiment discloses a method for using a heat circulation ventilation wall for a seedling greenhouse, including the following steps:

[0049] Step 1: Assembly of ventilation wall module 1: including stacking on top of each other, horizontal splicing and locking.

[0050] Vertical stacking assembly: Vertically stack the ventilation wall modules 1, insert the vertical assembly locking blocks 31 into the locking connection holes 37 of the upper and lower modules, and place sealing gaskets in the assembly sealing grooves 36 of adjacent modules; Horizontal splicing: Align multiple sets of vertically stacked modules horizontally, insert the horizontal assembly locking blocks 30 into the locking connection holes 37 of adjacent modules, so that the locking protrusions 32 of the horizontal assembly locking blocks 30 are engaged with the locking recesses 33 of the vertical assembly locking blocks 31; Locking and fixing: Screw the locking bolts 35 into the assembly connection holes 29, passing through the locking threaded holes 34 in the locking protrusions 32 and locking recesses 33, to complete the splicing of module 1 and form a complete wall.

[0051] Step 2, Heat circulation system connection: Connect the hot water heater and cold water tank to the water guide hole at the bottom of the lowest ventilation wall module 1 through the water guide pipe 28. The connection between the water guide pipe 28 and the hot water heater / cold water tank is controlled by a three-way valve. The thin water pipes 14 of the upper and lower adjacent modules 1 are automatically connected through the water guide hole to realize the water circulation of the whole wall.

[0052] Step 3: In winter, start synchronous motor 11. Through transmission gear 9 and synchronous belt 10, adjust all reflective strips 8 to a 45° focusing angle. Sunlight is reflected by the reflective strips 8 to the heat storage block 13 in the heat storage mounting frame 12. Open the three-way valve to connect the hot water boiler. Hot water enters the thin water pipe 14 through the water guide pipe 28. The heat storage block 13 absorbs the sunlight heat and keeps the hot water in the thin water pipe 14 warm. Open the automatic control valve of the air vent 20. External air enters the axial flow fan 18 through the air intake filter and blows through the heat-conducting fins 16 in the heat-conducting channel 17 to complete preheating. Start synchronous motor 24. Through transmission gear 22 and synchronous belt 23, adjust the angle of the movable air blowing frame 5. The preheated air is sent to the movable air blowing frame 5 through axial flow fan 29 and air guide frame 21 and blown towards the seedling area in the greenhouse.

[0053] Step 4: In summer, start synchronous motor 11 and adjust all reflective strips 8 to a 90° angle to block direct sunlight and reduce heat absorption by heat storage block 13; switch the three-way valve to connect the cold water tank, and cold water enters the thin water pipe 14 through the water guide pipe 28; outside air enters the axial flow fan 18 through the air guide port 20 and blows over the heat-conducting fins 16 to complete the cooling; adjust the angle of the movable air blowing frame 5 through synchronous motor 24, and the cooled air is sent into the greenhouse through the movable air blowing frame 5 to achieve low-temperature ventilation.

[0054] Step 5: Use the temperature sensor inside the ventilation wall module 1 to monitor the seedling environment temperature in the corresponding area in real time; if the temperature in a certain area is too high, connect the axial flow fan 18 through the air duct interface 25 and air duct 26 of the adjacent module to draw the air from the high temperature area to the low temperature area to achieve thermal circulation balance in the greenhouse.
