Description

Technical Field

[0001] The invention relates to the technical field of agricultural facilities, and in particular to a full-coverage internal heat preservation device. Background Art

[0002] The internal insulation of the solar greenhouse is mainly an important warming facility for winter production without heating: when night falls, the insulation curtain is unfolded. On the one hand, the insulation curtain itself has a low thermal conductivity, which can effectively block the conduction of indoor heat to the outside and reduce heat loss. On the other hand, it forms a relatively closed space, reduces air convection, and prevents hot air from quickly exchanging with the cold air outside, thereby maintaining the indoor temperature. At the same time, the surface of some insulation curtains can also reflect part of the heat radiated from the room, returning it back to the greenhouse, further enhancing the insulation effect. In these ways, the internal insulation facilities can maintain the temperature in the greenhouse within a range suitable for crop growth as much as possible during the night and other periods without sunlight.

[0003] The current solar greenhouse has a double-layer frame for internal insulation, which is costly and has a narrow maintenance space. The greenhouse has columns that occupy the greenhouse planting area and block the sunlight. The two-stage internal insulation requires two motors with poor economic benefits and a high failure rate. The two sections are not well sealed at the joint, which will cause indoor heat loss.

[0004] The disadvantage of existing solar greenhouse insulation is that it requires the addition of auxiliary tracks or columns in the greenhouse, which makes the internal space of the greenhouse discontinuous and fragmented in both visual and practical use. The columns will reduce the barrier-free planting or working space that can be actually used to a certain extent. It also has the following series of disadvantages:

[0005] 1. It will block the light, resulting in insufficient light in some areas, affecting plant photosynthesis, and thus affecting growth, development and yield.

[0006] 2. It will limit the growth space and hinder 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 in movement and increase the risk of collision.

[0008] 4. It will affect the equipment layout. The layout and use of some large equipment or machinery in the greenhouse may be restricted by the pillars.

[0009] The existing internal insulation of solar greenhouses without auxiliary tracks and columns, which realizes full coverage of greenhouses in winter, is generally two-stage without affecting the crop area, and requires two motors to drive. This will bring a series of adverse effects.

[0010] 1) Increased costs: The purchase cost of the two motors themselves and the subsequent maintenance and repair costs will be high, increasing the economic burden of greenhouse operations.

[0011] 2) Energy consumption: One more motor will increase the power consumption, which is not conducive to energy saving and reducing operating costs. Not only that, but it also requires installation space for two motors, which may make the layout of the greenhouse a little crowded and affect other equipment or operating space.

[0012] 2) Failure risk: The increase in the number of motors means that the probability of failure is relatively increased. Failure of any motor may affect the normal operation of the entire insulation system.

[0013] 3) System complexity: The control system of the two motors is relatively more complex, which may require higher technical requirements and more energy investment in regulation and management, and is also prone to problems such as coordination inconsistencies.

[0014] 4) Thermal insulation: The two sections of internal insulation controlled by two motors will leave gaps at the joints, which will lead to a decrease in the thermal insulation effect at night.

[0015] Generally speaking, its economic benefits are poor and work efficiency is low. Summary of the invention

[0032] pass Figures 1 to 6As shown, a full-coverage internal heat preservation 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 reel 3, a drum 4, a greenhouse frame 5, a motor 6, a tension beam 7, a tension rod 8, a plastic-coated transmission line 9, a sheet metal obstacle-crossing part 10, a steel wire track line 11 and an internal insulation blanket 12.

[0034] like Figure 2 As shown, the rear wall 1 is a load-bearing heat storage wall of the greenhouse, and is embedded and connected with the greenhouse frame 5. The greenhouse frame 5 is connected with the tie rod 8 to limit the greenhouse frame 5 from tilting left and right.

[0035] like Figure 6 As shown, the holes on the tie beam 7 are interlaced with the tie bars 8, and the sheet metal parts at the lower end of the tie beam 7 are connected by welding. The tie beam 7 is provided with a hole near its lower end, and two steel wire rails 11 start from the ground anchor and pass through the holes on both sides of the tie beam 7 and are finally fixed to the rear wall 1;

[0036] The heat preservation blanket 12 is hung on the sheet metal obstacle-crossing component 10 , and the sheet metal obstacle-crossing component 10 is connected to the steel wire track line 11 and the plastic-coated transmission line 9 .

[0037] like Figure 3 As shown, the motor 6 is connected to the reel bar 3, and the reel 4 is sleeved on the reel bar 3 and rotates with it; the plastic-coated transmission line 9 passes through the reel 4, the deep-V guide wheel 2, the other end of the tension beam 7, the ground guide wheel, the guide wheel on the tension beam 7 in sequence, and is connected back to the reel 4; the movement principle is that the motor 6 drives the reel bar 3, and the reel 4 fixed on the reel bar 3 rotates in a circle with the reel bar 3, and the plastic-coated transmission line 9 on the reel 4 passes through the guide wheel on the tension beam 7 to the front bottom corner guide wheel on the ground, and then is fixed to the first sheet metal obstacle crossing part, and the remaining plastic-coated transmission line 9 passes through the inner ring of the sheet metal obstacle crossing part 10 and is connected to the deep-V guide wheel 2 on the rear wall 1, and finally returns to the reel 4 to form a transmission cycle. When the reel 4 is driven by the motor 6 and the reel bar 3, the sheet metal obstacle crossing part 10 starts to move, and the inner insulation blanket 12 suspended under the sheet metal obstacle crossing part 10 performs a retracting and releasing movement.

[0038] Furthermore, a thermal insulation blanket can still be provided on the outside of the full-coverage internal thermal insulation device to achieve the purpose of internal and external thermal insulation.

[0039] When the inner insulation blanket 12 is ready to be unfolded, the motor 6 rotates, the winding bar 3 drives the reel 4, the plastic-coated transmission line 9 starts to move, and the end sheet metal obstacle crossing piece 10 starts to move accordingly. The insulation blanket 12 is unfolded with the movement of the sheet metal obstacle crossing piece 10, and the other sheet metal obstacle crossing pieces 10 move accordingly; when the insulation blanket 12 is ready to be retracted, the motor 6 rotates in the opposite direction, the winding bar 3 drives the reel 4, the plastic-coated transmission line 9 starts to move in the opposite direction, and the end sheet metal obstacle crossing pieces 10 start to move accordingly; due to the setting of the deep V guide wheel 2, the sheet metal obstacle crossing piece 10 cannot cross the deep V guide wheel 2. As the plastic-coated transmission line 9 moves, the sheet metal obstacle crossing pieces 10 continue to gather, and finally the inner insulation blanket 12 is retracted.

[0040] The full-coverage internal heat preservation device of the present invention achieves the following effects:

[0041] 1. Reduce costs: Compared with double-layer frames, it can reduce material and construction costs.

[0042] 2. Increase maintenance space: solve the problem of narrow maintenance space and facilitate later maintenance work.

[0043] 3. Avoid sunlight blocking: It eliminates the disadvantage of pillars blocking sunlight, making the light in the greenhouse more uniform and sufficient.

[0044] 4. Reduce area occupation: No more columns occupy the greenhouse area, which improves land utilization.

[0045] 5. Facilitate mechanical operation: It provides a wider space, which is conducive to the operation of machinery in the greenhouse.

[0046] 6. Improve economic efficiency: Under the premise of ensuring functionality, it may have better cost-effectiveness.

[0047] 7. Improved sealing: Compared with the two-stage type, its sealing performance may be better, which helps to maintain a stable environment in the greenhouse.
