Description

Technical Field

[0001] This invention relates to the field of greenhouse technology, specifically to a lightweight greenhouse. Background Technology

[0002] A greenhouse, also known as a hothouse, is a facility that allows light to pass through while maintaining (or heating) the soil for cultivating plants. During seasons unsuitable for plant growth, it provides a greenhouse environment to promote growth and increase yields. It is primarily used for cultivating or raising seedlings of warm-weather vegetables, flowers, and trees during colder seasons.

[0003] The existing greenhouses have gradually revealed their shortcomings during use, mainly in the following aspects:

[0004] First, the extensive use of steel structural support components increases construction costs. Specifically, to improve the wind resistance of greenhouses, a large number of support components are usually added between adjacent frame structures to strengthen the structural strength of the greenhouse. Therefore, the extensive use of steel structural support components during greenhouse construction significantly increases the construction cost.

[0005] Secondly, the supporting facilities have low versatility, which increases the cost of use. Specifically, the design of a greenhouse includes an irrigation system and a heating system. After the main structure of the greenhouse is completed, the supporting facilities for the irrigation system and the heating system need to be installed separately. The supporting facilities between different systems cannot be shared, so the supporting facilities have low versatility and increase the cost of use.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0007] To address the shortcomings of existing technologies, the technical problem to be solved by this invention is to provide a lightweight greenhouse that is lightweight and can significantly reduce the amount of steel structure support components used without compromising wind resistance, thereby reducing the construction cost of the greenhouse.

[0008] The greenhouse's supporting facilities are highly versatile, reducing the greenhouse's operating costs.

[0009] To address the above problems, the present invention provides the following technical solution:

[0010] A lightweight greenhouse includes a hardened ground surface. Several fixed outer frames are horizontally arranged side-by-side on the top of the hardened ground surface. An inner frame is located directly below the outer frames and is fixedly connected to the hardened ground surface. A covering film is laid on the outer surface of the outer frames. Both the outer and inner frames are U-shaped structures. Several sliding supports are located between the arc-shaped structures of two adjacent outer frames. Several fixed support plates are located between the vertical structures of two adjacent outer frames. The opposite ends of the fixed support plates are fixedly connected to their adjacent two outer frames. Several fixed reinforcing ribs are located between the vertical structures of the outer and inner frames. The two ends of the fixed reinforcing ribs are fixedly connected to the outer and inner frames respectively. A driving assembly is located on the top of the hardened ground surface.

[0011] The sliding support includes a sliding support plate. The end of the outer frame is provided with a horizontal clearance groove. A connecting plate is provided in the clearance groove and in frictional contact with its inner wall. The opposite ends of the connecting plate extend out of the clearance groove and are fixedly connected to the two adjacent sliding support plates.

[0012] As an optimized solution, the opposite end faces of the outer frame and the inner frame are provided with sliding grooves. Several sliding reinforcing ribs are provided between the arc-shaped structures of the outer frame and the inner frame. Both the sliding reinforcing ribs and the fixed reinforcing ribs are X-shaped structures. The two ends of the sliding reinforcing ribs extend into the two sliding grooves respectively and make frictional contact with the outer frame and the inner frame. Several positioning grooves for positioning the sliding reinforcing ribs are provided on the inner wall of the sliding grooves. A fixed plate is horizontally inserted through the end of the sliding reinforcing rib. External connecting pipes are fixedly installed on the top of the fixed plate at the positions on both sides of the outer frame. The top of the external connecting pipes is fixedly connected to the bottom of the sliding support plate.

[0013] As an optimized solution, the sliding support plate has an internal receiving cavity, and an upper partition is fixed to the inner wall of the receiving cavity, dividing the receiving cavity into upper and lower parts. The top of the sliding support plate has several air jet holes communicating with the upper half of the receiving cavity, and the bottom of the sliding support plate has several drainage grooves communicating with the lower half of the receiving cavity. An atomizing plate is installed in the drainage groove. The fixed plate has a rectangular groove inside, and a lower partition is fixed to the inner wall of the rectangular groove, dividing the rectangular groove into upper and lower parts. The upper and lower ports of the external connecting pipe are connected to the lower half of the receiving cavity and the upper half of the rectangular groove, respectively. The top of the lower partition has two internal connecting pipes communicating with the lower half of the rectangular groove, and the upper ports of the internal connecting pipes pass upward through the external connecting pipes and communicate with the upper half of the receiving cavity.

[0014] As an optimized solution, a venting hose and a liquid hose are fixedly connected to the end of the fixed plate located on the side. The liquid hose and the venting hose are connected to the upper half and the lower half of the rectangular groove respectively. The venting hose is connected to the heating fan, and the liquid hose is connected to the booster pump.

[0015] As an optimized solution, the drive assembly includes a fixed U-shaped plate fixedly mounted on the top of the hardened ground. The inner bottom of the fixed U-shaped plate is provided with a horizontally sliding U-shaped plate. The sliding U-shaped plate is provided with a rotating shaft. The two ends of the rotating shaft are rotatably connected to the relative inner walls of the sliding U-shaped plate. The outer wall of the rotating shaft is provided with several fixedly mounted swing plates arranged horizontally side by side. The top of the swing plates is provided with a lifting plate. The bottom end of the lifting plate extends into the swing plate and is vertically slidably connected to the swing plate. The top of the lifting plate is fixedly connected with a drive plate. The top of the drive plate is provided with a slot.

[0016] Insert plates are fixedly connected to the bottom of the sliding support plate and the end of the uppermost fixed support plate.

[0017] As an optimized solution, a horizontally arranged drive telescopic cylinder is fixedly provided on the inner wall of the fixed U-shaped plate, and the telescopic end of the drive telescopic cylinder is fixedly connected to the sliding U-shaped plate.

[0018] As an optimized solution, a drive motor is fixedly provided at the end of the sliding U-shaped plate, and the output end of the drive motor passes through the sliding U-shaped plate and is fixedly connected to the rotating shaft.

[0019] As an optimized solution, a vertically arranged lifting and telescopic cylinder is fixedly provided at the end of the swing plate, and the telescopic end of the lifting and telescopic cylinder is fixedly connected to the drive plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. During windy weather, adjust the distribution of sliding support plates and sliding reinforcing ribs according to the wind direction. The lifting telescopic cylinder drives the drive plate upward until the bottom plate of one row of sliding support plates is fully inserted into the slot. The drive telescopic cylinder then drives the sliding U-shaped plate to slide horizontally, thereby moving the entire row of sliding support plates horizontally until the sliding reinforcing ribs disengage from the positioning slots. The drive motor then drives the rotating shaft to rotate, moving the sliding support plates and sliding reinforcing ribs towards the windward side of the greenhouse. After the sliding support plates and sliding reinforcing ribs reach their corresponding positions, the sliding U-shaped plate resets, and the sliding reinforcing ribs re-enter the positioning slots for limiting. Repeat the above process to move some of the sliding support plates and sliding reinforcing ribs from the leeward side of the greenhouse to the windward side (e.g., ...). Figure 7As shown in the figure, this enhances the wind resistance of the greenhouse. The greenhouse is lightweight, and by adjusting the position of the sliding support plate and the sliding reinforcing rib, the amount of steel structure support components used can be greatly reduced without reducing the wind resistance of the greenhouse, thus reducing the construction cost of the greenhouse.

[0022] 2. After the sliding support plate and sliding reinforcing rib are adjusted, the drive motor drives the rotating shaft to rotate until the slot on the drive plate aligns with the insert plate on the windward fixed support plate. The lifting and telescopic cylinder then moves the drive plate until the insert plate on the windward fixed support plate is fully inserted into the slot. At this point, the drive plate and the fixed support plate are in contact (e.g., ...). Figure 7 As shown in the figure, the drive plate can provide support for the windward side of the greenhouse, further improving the wind resistance of the greenhouse;

[0023] 3. When irrigating the plants in the greenhouse, the liquid is pressurized by the booster pump and enters the upper part of the rectangular trough through the liquid inlet hose. The liquid in the upper part of the rectangular trough enters the lower part of the receiving chamber through the external connecting pipe. The liquid in the lower part of the receiving chamber is atomized by the atomizing plate and sprayed downwards to irrigate the plants in the greenhouse. When heating the greenhouse, the hot air generated by the heating fan enters the lower part of the rectangular trough through the ventilation hose. The hot air in the lower part of the rectangular trough enters the upper part of the receiving chamber through the internal connecting pipe and is sprayed into the greenhouse through the air jet, thereby heating the interior of the greenhouse. In addition, the heating system can not only heat the greenhouse, but also melt the snow on the covering film when there is heavy snow. Therefore, the heating system can also be used for snow removal in the greenhouse. It can be seen that the supporting facilities of this greenhouse are highly versatile and reduce the operating cost of the greenhouse. Attached Figure Description

[0034] like Figures 1 to 7 As shown, a lightweight greenhouse includes a hardened ground 1. Several fixed outer frames 5 are arranged horizontally side by side on the top of the hardened ground 1. An inner frame 4 is located directly below the outer frames 5 and is fixedly connected to the hardened ground 1. A covering film 3 is laid on the outer surface of the outer frames 5. Both the outer frames 5 and the inner frames 4 are U-shaped structures. Several sliding support members 6 are provided between the arc-shaped structures of two adjacent outer frames 5.

The opposite ends of the fixed support plates 7 are fixedly connected to the two adjacent outer frames 5. Several fixed reinforcing ribs 8 are provided between the vertical structures of the outer frames 5 and the inner frames 4. The two ends of the fixed reinforcing ribs 8 are fixedly connected to the outer frames 5 and the inner frames 4. A driving assembly 2 is provided on the top of the hardened ground 1.

[0035] The sliding support 6 includes a sliding support plate 12. The end of the outer frame 5 is provided with a horizontal clearance groove 11. The clearance groove 11 is provided with a connecting plate 13 that rubs against its inner wall. The opposite ends of the connecting plate 13 extend to the outside of the clearance groove 11 and are fixedly connected to the two adjacent sliding support plates 12.

[0036] The outer frame 5 and the inner frame 4 are provided with sliding grooves 10 on their opposite end faces. Several sliding reinforcing ribs 9 are provided between the arc-shaped structures of the outer frame 5 and the inner frame 4. Both the sliding reinforcing ribs 9 and the fixed reinforcing ribs 8 are X-shaped structures.

The top of the fixed plates 14 is fixedly provided with external connecting pipes 15 on both sides of the outer frame 5. The top of the external connecting pipes 15 is fixedly connected to the bottom of the sliding support plate 12.

[0037] The sliding support plate 12 has an internal cavity 22. An upper partition 21 is fixed to the inner wall of the cavity 22, dividing the cavity 22 into upper and lower parts. The top of the sliding support plate 12 has several jet holes 20 that communicate with the upper part of the cavity 22. The bottom of the sliding support plate 12 has several drainage grooves 27 that communicate with the lower part of the cavity 22. An atomizing plate 26 is installed in the drainage groove 27. The fixed plate 14 has a rectangular groove 23 inside. A lower partition 24 is fixed to the inner wall of the rectangular groove 23, dividing the rectangular groove 23 into upper and lower parts. The upper and lower ports of the external connecting pipe 15 are connected to the lower part of the cavity 22 and the upper part of the rectangular groove 23, respectively. The top of the lower partition 24 has two internal connecting pipes 25 that communicate with the lower part of the rectangular groove 23. The upper ports of the internal connecting pipes 25 pass upward through the external connecting pipes 15 and communicate with the upper part of the cavity 22.

[0038] A ventilation hose 17 and a liquid hose 18 are fixedly connected to the end of the fixed plate 14 located on the side. The liquid hose 18 and the ventilation hose 17 are connected to the upper half and lower half of the rectangular groove 23 respectively. The ventilation hose 17 is connected to the heating fan, and the liquid hose 18 is connected to the booster pump.

[0039] The drive assembly 2 includes a fixed U-shaped plate 28 fixedly installed on the top of the hardened ground 1. The bottom of the fixed U-shaped plate 28 is provided with a horizontally sliding U-shaped plate 30. The sliding U-shaped plate 30 is provided with a rotating shaft 35. The two ends of the rotating shaft 35 are rotatably connected to the relative inner walls of the sliding U-shaped plate 30. The outer wall of the rotating shaft 35 is provided with several fixedly installed swing plates 34 horizontally side by side. The top of the swing plate 34 is provided with a lifting plate 33. The bottom end of the lifting plate 33 extends into the swing plate 34 and is vertically slidably connected to the swing plate 34. The top of the lifting plate 33 is fixedly connected with a drive plate 32. The top of the drive plate 32 is provided with a slot 37.

[0040] Insert plates 16 are fixedly connected to the bottom of the sliding support plate 12 and the end of the uppermost fixed support plate 7.

[0041] A horizontally arranged drive telescopic cylinder 29 is fixedly installed on the inner wall of the fixed U-shaped plate 28, and the telescopic end of the drive telescopic cylinder 29 is fixedly connected to the sliding U-shaped plate 30.

[0042] A drive motor 36 is fixedly provided at the end of the sliding U-shaped plate 30. The output end of the drive motor 36 passes through the sliding U-shaped plate 30 and is fixedly connected to the rotating shaft 35.

[0043] The end of the swing plate 34 is fixedly provided with a vertically arranged lifting telescopic cylinder 31, and the telescopic end of the lifting telescopic cylinder 31 is fixedly connected to the drive plate 32.

[0044] The working principle of this device is as follows:

[0045] During windy weather, the distribution of the sliding support plates 12 and sliding reinforcing ribs 9 is adjusted according to the wind direction. The lifting telescopic cylinder 31 drives the drive plate 32 to move upward until the insert plate 16 at the bottom of one row of sliding support plates 12 is fully inserted into the slot 37. The drive telescopic cylinder 29 drives the sliding U-shaped plate 30 to slide horizontally, thereby driving the row of sliding support plates 12 to move horizontally until the sliding reinforcing ribs 9 disengage from the positioning groove 19. The drive motor 36 drives the rotating shaft 35 to rotate, thereby driving the sliding support plates 12 and sliding reinforcing ribs 9 to move towards the windward side of the greenhouse. After the sliding support plates 12 and sliding reinforcing ribs 9 move to the corresponding positions, the sliding U-shaped plate 30 resets, and the sliding reinforcing ribs 9 enter the positioning groove 19 for limiting. The above process is repeated to move some of the sliding support plates 12 and sliding reinforcing ribs 9 from the leeward side of the greenhouse to the windward side (e.g., Figure 7 As shown in the figure, the wind resistance of the greenhouse is enhanced. The greenhouse is lightweight. By adjusting the position of the sliding support plate 12 and the sliding reinforcing rib 9, the amount of steel structure support components used can be greatly reduced without reducing the wind resistance of the greenhouse, thus reducing the construction cost of the greenhouse.

[0046] After the sliding support plate 12 and the sliding reinforcing rib 9 are adjusted, the drive motor 36 drives the rotating shaft 35 to rotate until the slot 37 on the drive plate 32 is aligned with the insert plate 16 on the windward fixed support plate 7. The lifting telescopic cylinder 31 drives the drive plate 32 to move until the insert plate 16 on the windward fixed support plate 7 is fully inserted into the slot 37. At this time, the drive plate 32 abuts against the fixed support plate 7 (e.g., Figure 7 As shown, the drive plate 32 can provide support for the windward side of the greenhouse, further improving the wind resistance of the greenhouse;

[0047] When irrigating the plants in the greenhouse, the liquid, pressurized by a booster pump, enters the upper part of the rectangular trough 23 through the liquid inlet hose 18. The liquid in the upper part of the rectangular trough 23 enters the lower part of the receiving cavity 22 through the external connecting pipe 15. The liquid in the lower part of the receiving cavity 22 is atomized by the atomizing plate 26 and sprayed downwards, thus irrigating the plants in the greenhouse. When heating the greenhouse, hot air generated by the heating fan enters the lower part of the rectangular trough 23 through the ventilation hose 17. The hot air in the lower half of the 3-section enters the upper half of the receiving cavity 22 through the inner connecting pipe 25 and is sprayed into the greenhouse through the jet nozzle 20, thereby heating the inside of the greenhouse. In addition, the heating system can not only heat the greenhouse, but also melt the snow on the covering film 3 when there is heavy snow. Therefore, the heating system can also be used for snow removal in the greenhouse. It can be seen that the supporting facilities of the greenhouse are highly versatile and reduce the operating cost of the greenhouse.
