Abstract
Description
Technical Field
[0001] This invention relates to the field of agricultural facility technology, and in particular to a full-coverage internal insulation device. Background Technology
[0002] The internal insulation of a solar greenhouse is a crucial heating system primarily used during winter production when no additional heating is required. At night, the insulation curtain is deployed. Firstly, the curtain itself has a low thermal conductivity, effectively preventing heat loss from the interior. Secondly, it creates a relatively enclosed space, reducing air convection and preventing rapid exchange of hot air with cold outside air, thus maintaining the indoor temperature. Additionally, some insulation curtain surfaces can reflect some of the heat radiated from the interior, allowing it to return to the greenhouse and further enhancing the insulation effect. Through these methods, the internal insulation system can maintain the greenhouse temperature within a suitable range for crop growth during nighttime and other sunless periods.
[0003] Current greenhouses typically employ a double-layered insulation system, which is costly and restricts maintenance space. Internal columns occupy planting area and block sunlight. Two-section internal insulation requires two motors, resulting in poor economic efficiency, a high failure rate, and poor sealing at the joints, leading to heat loss.
[0004] The existing methods of heat preservation in solar greenhouses have the disadvantage of requiring the addition of auxiliary tracks or columns, which makes the interior space discontinuous and feels fragmented both visually and practically. The columns also reduce the usable unobstructed planting or working space. Furthermore, they have the following disadvantages:
[0005] 1. It will block the light, resulting in insufficient light in some areas, which will affect the photosynthesis of plants, and thus affect their growth, development and yield.
[0006] 2. It will restrict the growth space, hindering the growth of plants in certain directions.
[0007] 3. It will hinder workers' operations. When workers walk and work in the greenhouse, the pillars may cause inconvenience and increase the risk of collision.
[0008] 4. It will affect equipment layout. The layout and use of some large equipment or machinery in the greenhouse may be restricted by the columns.
[0009] Existing trackless and pillarless greenhouses, which achieve full winter greenhouse coverage without affecting crop area, typically employ a two-section system requiring two motors for internal insulation. This leads to a series of adverse effects.
[0010] 1) Increased costs: The purchase cost of the two motors themselves, as well as the subsequent maintenance and repair costs, will be higher, increasing the economic burden of greenhouse operation.
[0011] 2) Energy consumption: Adding an extra motor increases energy consumption, which is detrimental to energy conservation and reducing operating costs. Furthermore, space needs to be allocated for the installation of two motors, potentially making the greenhouse layout somewhat cramped and affecting the operation of other equipment.
[0012] 2) Failure risk: An increased number of motors means a relatively higher probability of failure. Failure of any one motor may affect the normal operation of the entire insulation system.
[0013] 3) System complexity: The control system of two motors is relatively more complex. It may require higher technical requirements and more effort in regulation and management, and it is also prone to problems such as inconsistency in coordination.
[0014] 4) Thermal insulation: The two sections of internal insulation controlled by two motors will leave gaps at the splicing points, which will reduce the thermal insulation effect at night.
[0015] Overall, its economic benefits are poor and its work efficiency is low. Summary of the Invention

[0021] Furthermore, the sheet metal obstacle-crossing component 10 includes two symmetrical inner rings, a straight plate, and a circular ring; the inner ring is located on one side of the straight plate, and the circular ring is located on the other side of the straight plate; the steel wire track line 11 and the plastic-coated transmission line 9 pass through the inner ring respectively; the inner insulation blanket 12 is suspended by the circular ring.
[0022] Furthermore, the greenhouse frame 5 is a connection between straight segments and curved segments.

[0032] pass Figures 1 to 6As shown, a full-coverage internal insulation device is provided.
[0033] like Figure 1 As shown, the full-coverage internal insulation device includes a rear wall 1, a deep V guide wheel 2, a roller 3, a drum 4, a greenhouse frame 5, a motor 6, a tie beam 7, a tie rod 8, a plastic-coated transmission line 9, sheet metal obstacle-crossing parts 10, a steel wire track line 11, and an internal insulation blanket 12.
[0034] like Figure 2 As shown, the rear wall 1 is the load-bearing and heat storage component of the greenhouse and is embedded and connected to the greenhouse frame 5. The greenhouse frame 5 is connected to the tie rod 8 to restrict the left and right tilt of the greenhouse frame 5.
[0035] like Figure 6 As shown, the holes on the tie beam 7 are interlocked with the tie rods 8, and the sheet metal parts at the lower end of the tie beam 7 are connected by welding. The tie beam 7 has holes near its lower end, and two steel wire tracks 11 start from the ground anchor, pass through the holes on both sides of the tie beam 7, and are finally fixed to the rear wall 1;
[0036] The thermal insulation blanket 12 is suspended on the sheet metal obstacle crossing component 10, which is connected to the steel wire track line 11 and the plastic-coated transmission line 9.
[0037] like Figure 3 As shown, motor 6 is connected to reel 3, and drum 4 is fitted onto reel 3 and rotates with it. The plastic-coated transmission line 9 passes sequentially through drum 4, deep V guide wheel 2, the other end of pull beam 7, ground guide wheel, and guide wheel on pull beam 7, before returning to drum 4. The motion principle is that motor 6 drives reel 3, and drum 4, fixed on reel 3, rotates in a circle with reel 3. The plastic-coated transmission line 9 on drum 4 passes through guide wheel on pull beam 7 to front bottom corner guide wheel on the ground, and is then fixed to the first sheet metal obstacle-crossing component. The remaining plastic-coated transmission line 9 passes through the inner ring of sheet metal obstacle-crossing component 10 and connects to deep V guide wheel 2 on rear wall 1, finally returning to drum 4 to form a transmission cycle. When drum 4 is driven by motor 6 and reel 3, sheet metal obstacle-crossing component 10 begins to move, and inner insulation blanket 12 suspended under sheet metal obstacle-crossing component 10 performs retraction and expansion movements.
[0038] Furthermore, an insulation blanket can still be installed on the outside of this full-coverage internal insulation device to achieve the purpose of double insulation inside and outside.
[0039] When preparing to unfold the inner insulation blanket 12, the motor 6 rotates, the winding rod 3 drives the drum 4, the plastic-coated transmission line 9 begins to move, and the end sheet metal obstacle-crossing parts 10 begin to move accordingly. The insulation blanket 12 unfolds with the movement of the sheet metal obstacle-crossing parts 10, and the remaining sheet metal obstacle-crossing parts 10 move accordingly. When preparing to retract the insulation blanket 12, the motor 6 rotates in the opposite direction, the winding rod 3 drives the drum 4, the plastic-coated transmission line 9 begins to move in the opposite direction, and the end sheet metal obstacle-crossing parts 10 begin to move accordingly. Due to the setting of the deep V guide wheel 2, the sheet metal obstacle-crossing parts 10 cannot cross the deep V guide wheel 2. As the plastic-coated transmission line 9 moves, the sheet metal obstacle-crossing parts 10 continuously converge, and finally the inner insulation blanket 12 is retracted.
[0040] The full-coverage internal insulation device of the present invention achieves the following effects:
[0041] 1. Reduced costs: Compared to a double-layer frame, it can reduce material and construction costs.
[0042] 2. Increased maintenance space: This solves the problem of limited maintenance space and facilitates later maintenance work.
[0043] 3. Avoids sun shading: Eliminates the drawbacks of pillars blocking sunlight, making the light inside the greenhouse more even and sufficient.
[0044] 4. Reduced space occupation: No more pillars occupying greenhouse space, improving land utilization.
[0045] 5. Facilitates mechanical operation: It provides a more open space, which is conducive to the operation of machinery inside the greenhouse.
[0046] 6. Improved cost-effectiveness: While ensuring functionality, it may offer better value for money.
[0047] 7. Improved sealing: Compared to the two-stage design, it may have better sealing performance, which helps to maintain a stable environment inside the greenhouse.
