Description

Technical Field

[0001] This invention belongs to the technical field of seedling equipment, specifically a solar greenhouse for orchid cultivation. Background Technology

[0002] Orchids are an important plant resource, possessing significant medicinal, ornamental, and scientific research value. The Tibet Autonomous Region boasts abundant orchid resources; however, its intense solar radiation and high ultraviolet radiation far exceed the tolerance range of orchids (which prefer shade and soft, diffused light). Strong direct sunlight easily leads to leaf burn, stunted growth, and even plant death. Furthermore, existing shading facilities (such as fixed shade nets) are inconvenient to adjust and cannot flexibly cope with the rapidly changing light intensity and angle in Tibet (such as low-angle, strong sunlight in the early morning and late evening), failing to accurately provide the stable, soft light environment required by orchids.

[0003] Most areas of the Tibet Autonomous Region have low average annual temperatures and extreme diurnal temperature variations, especially in spring, autumn, and winter. This low-temperature environment significantly compresses the effective growing season for orchids and causes them to remain in a state of low physiological activity for extended periods.

[0004] Existing greenhouse insulation measures (such as thickening the covering layer and laying temporary insulation blankets) have significant drawbacks: poor flexibility, inconvenience in moving, and additional covering layers reduce light transmittance.

[0005] Therefore, it is necessary to provide a solar greenhouse for orchid cultivation to solve the problems mentioned in the background art. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a solar greenhouse for orchid cultivation, comprising a support frame, a shading device, a heat preservation device, and a lifting device. The support frame is composed of multiple support rods spliced ​​together. Two sets of vertically distributed shading devices are installed on the top of the support frame. Heat preservation devices are respectively provided around the support frame and below the shading devices. A lifting device is provided on one side inside the support frame.

[0007] The support frame is symmetrically equipped with four casters at its bottom.

[0008] Furthermore, as a preferred embodiment, the sunshade device includes two parallel guide rails, each with a base at both ends; a first roller is rotatably mounted between the bases at one end of each of the two guide rails, one end of which is fixed to the output shaft of a sunshade motor located on the other side of the base; pulleys are mounted on the inner surfaces of the bases at the other ends of the two guide rails, close to each other, and each pulley is wound with a movable traction rope; a sunshade net is slidably mounted between the two guide rails, one edge of which is fixed to the first roller, and both ends of the other edge are fixedly connected to the corresponding traction ropes; the other end of each traction rope passes over its corresponding pulley and is fixed to the first roller.

[0009] Furthermore, as a preferred embodiment, the light transmittance of the shading nets in the two sets of shading devices are different.

[0010] Furthermore, as a preferred embodiment, the heat preservation device includes a second rotating shaft, which is rotatably connected to the support frame; one end of the second rotating shaft is fixed to the output shaft of the heat preservation motor located on the other side of the support frame; a heat preservation layer is slidably disposed between the support rods at both ends of the second rotating shaft, and one edge of the heat preservation layer is fixed to the second roller.

[0011] Furthermore, as a preferred embodiment, an air insulation layer is formed between the sunshade device and the insulation device directly below it, and a ventilation window is provided on the insulation layer directly below the sunshade device.

[0012] Furthermore, as a preferred embodiment, the lifting device includes a lifting plate vertically fixed to the inner side of the support frame; two linear guide rails are arranged parallel to each other on the lifting plate, and a lead screw is vertically arranged between the two linear guide rails; the two ends of the lead screw are rotatably connected to a lead screw support seat fixed to the lifting plate; a lead screw nut that can move up and down is sleeved on the lead screw, and the lead screw nut is fixed to a nut seat that is slidably arranged on the linear guide rail; a tripod is fixed to the side of the nut seat away from the lead screw.

[0013] A motor mounting base is horizontally installed on the side of the lifting plate closest to the ground. A lifting motor is vertically installed on the motor mounting base. The output end of the lifting motor faces downward and is driven by the bottom end of the lead screw through a belt drive device located below its output end.

[0014] Furthermore, as a preferred embodiment, a tray base is slidably disposed on the support frame above the tripod, and a tray is disposed on the tray base.

[0015] Furthermore, as a preferred embodiment, a photosensitive sensor and a temperature sensor are disposed in the middle position inside the support frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention employs two independent shading devices, each with a shading net of varying shading rates mounted on an independent first roller. By controlling the unfolding and rewinding actions of the two shading nets and combining them, multiple levels of shading rate adjustment can be achieved. Simultaneously, both shading nets can be completely rolled to one side to achieve full illumination.

[0018] This invention employs a lifting device that allows adjustment of the tray's height within the support frame. During periods of low-angle sunlight, such as in the morning or afternoon, the angle between the shading device and the sunlight can cause some sunlight to penetrate the gaps in the shading net and strike the plants at an angle, causing damage. By adjusting the tray's height within the device, the lifting device ensures that the plants remain within the effective projection coverage of the shading net, thus preventing damage from oblique sunlight.

[0019] This invention employs a combination of a heat preservation device and a sunshade device, both installed at different heights on a support frame and running on their respective tracks, allowing for independent operation. An air insulation layer is formed between the sunshade device and the heat preservation device located directly below it. This structure effectively blocks the direct exchange of heat between indoors and outdoors, inhibits heat conduction and convection, and significantly reduces heat transfer efficiency, thereby achieving excellent heat preservation effects.

Detailed Implementation

[0026] Please see Figures 1-5 In this embodiment of the invention, a solar greenhouse for orchid cultivation includes a support frame 1, a shading device 2, a heat preservation device 3, and a lifting device 4. The support frame 1 is assembled from multiple support rods 11. Two sets of shading devices 2 are installed on the top of the support frame 1. Heat preservation devices 3 are respectively provided around the support frame 1 and below the shading devices 2. A lifting device 4 is provided on one side inside the support frame 1.

[0027] The bottom of the support frame 1 is symmetrically equipped with four casters 7, which have a locking function and can move on the pre-set slide rails on the greenhouse floor.

[0028] In this embodiment, the sunshade device 2 includes two parallel guide rails 21, each with a base 22 at both ends; a first roller 23 is rotatably mounted between the bases 22 at one end of each guide rail 21, one end of the first roller 23 being fixed to the output shaft of a sunshade motor 24 located on the other side of the base 22; pulleys 26 are mounted on the inner surfaces of the bases 22 at the other ends of the two guide rails 21, close to each other, and each pulley 26 is wound with a movable traction rope 27; a sunshade net 25 is slidably mounted between the two guide rails 21, one edge of the sunshade net 25 being fixed to the first roller 23, and the other... The two ends of one edge are fixedly connected to the corresponding traction rope 27; the other end of each traction rope 27 passes around its corresponding pulley 26 and is fixed to the first roller 23; when the shade net 25 is unfolded, the shade motor 24 drives the first roller 23 to rotate in the forward direction. At this time, the shade net 25 unfolds along the guide rail 21 under the traction of the traction rope 27, and the traction rope 27 is wound onto the first roller 23; when the shade net 25 is rolled up, the shade motor 24 drives the first roller 23 to rotate in the reverse direction, and the shade net 25 is wound onto the first roller 23 along the guide rail 21, while the traction rope 27 is released from the first roller 23.

[0029] In a preferred embodiment, the light transmittance of the shade nets 25 in the two sets of shade devices 2 is different; by controlling the unfolding and rewinding actions of the two shade nets 25 in combination, multiple levels of shading rate adjustment can be achieved. At the same time, both shade nets 25 can be completely rolled up to one side to achieve full illumination.

[0030] In this embodiment, the heat preservation device 3 includes a second rotating shaft 31, which is rotatably connected to the support frame 1. One end of the second rotating shaft 31 is fixed to the output shaft of the heat preservation motor 32 located on the other side of the support frame 1. A heat preservation layer 33 is slidably disposed between the support rods 11 at both ends of the second rotating shaft 31, and one edge of the heat preservation layer 33 is fixed to the second roll 31. When the heat preservation layer 33 is unfolded, the heat preservation motor 32 drives the second rotating shaft 31 to rotate in the forward direction, and the second rotating shaft 31 drives the heat preservation layer 33 to unfold along the support rods 11. When the heat preservation layer 33 is rolled up, the heat preservation motor 32 drives the second rotating shaft 31 to rotate in the reverse direction, and the heat preservation layer 33 is rolled up along the support rods 11 onto the second rotating shaft 31.

[0031] In this embodiment, an air insulation layer 6 is formed between the sunshade device 2 and the insulation device 3 directly below it. A ventilation window 5 is provided on the insulation layer 33 directly below the sunshade device 2. The air insulation layer 6 can effectively block the direct exchange of heat between indoors and outdoors, suppress heat conduction and heat convection, and significantly reduce heat transfer efficiency, thereby achieving excellent heat preservation effect.

[0032] In this embodiment, the lifting device 4 includes a lifting plate 41 vertically fixed to the inner side of the support frame 1; two linear guide rails 42 are arranged parallel to each other on the lifting plate 41, and a lead screw 43 is vertically arranged between the two linear guide rails 42. The two ends of the lead screw 43 are rotatably connected to the lead screw 43 support seat 44 fixed on the lifting plate 41; a lead screw nut 48 that can move up and down is sleeved on the lead screw 43, and the lead screw nut 48 is fixed to a nut seat 49 that is slidably arranged on the linear guide rail 42; a tripod 410 is fixed on the side of the nut seat 49 away from the lead screw 43.

[0033] A motor mounting base 45 is horizontally mounted on the side of the lifting plate 41 closest to the ground. A lifting motor 46 is vertically mounted on the motor mounting base 45, with its output end facing downwards. The motor is driven by a belt drive device 47 located below its output end and connected to the bottom end of a lead screw 43. During periods of low-angle sunlight in the morning or afternoon, the angle between the shading device and the sunlight may cause some sunlight to penetrate the gaps in the shading net and shine obliquely onto the plants, causing damage. In this case, the lifting motor 46 drives the lead screw 43 to rotate via the belt drive device 47. The rotating lead screw 43 forms a threaded engagement with a lead screw nut 48, which in turn pushes the lead screw nut 48, fixed on the nut seat 49, to move vertically upwards along the linear guide rail 42. This ensures that the plants are always within the effective projection coverage of the shading net 25, thereby avoiding damage caused by oblique sunlight.

[0034] In a preferred embodiment, a tray base 8 is slidably disposed on the support frame 1 above the tripod 410, and a tray 81 is disposed on the tray base 8. The tripod 410 can drive the tray 81 to move up and down.

[0035] In this embodiment, a photosensitive sensor and a temperature sensor are provided in the middle position inside the support frame 1.

[0036] Specifically, when the photosensor detects that the light intensity exceeds a set threshold (the range suitable for orchid growth), the shade net 25 automatically unfolds: the shade motor 24 drives the first roller 23 to rotate clockwise. At this time, the shade net 25 unfolds along the guide rail 21 under the traction of the traction rope 27, and the traction rope 27 is wound onto the first roller 23. When the light intensity is below the threshold, it automatically retracts: the shade motor 24 drives the first roller 23 to rotate counterclockwise, and the shade net 25 is wound onto the first roller 23 along the guide rail 21, while the traction rope 27 is released from the first roller 23. Two independent shading devices 2 are used, each equipped with shade nets 25 with different shading rates. The unfolding and retracting actions of the two shade nets 25 are combined and superimposed according to the shading requirements to achieve multi-level shading rate adjustment. At the same time, both shade nets 25 can be completely retracted to one side to achieve full illumination.

[0037] During periods of low-angle sunlight in the morning or afternoon, the angle between the shading device and the sunlight may cause some sunlight to penetrate the gaps in the shading net and shine obliquely onto the plants, causing damage. In this situation, activating the lifting device 4 causes the lifting motor 46 to drive the lead screw 43 to rotate via the belt drive device 47. The rotating lead screw 43 engages with the lead screw nut 48, which in turn pushes the lead screw nut 48, fixed on the nut seat 49, to move vertically upwards along the linear guide rail 42. This ensures that the plants remain within the effective projection coverage of the shading net 25, thus preventing damage caused by oblique sunlight.

[0038] When the temperature sensor detects that the internal temperature is lower than the set threshold (the range suitable for orchid growth), the insulation layer 33 is automatically deployed: the insulation motor 32 drives the second rotating shaft 31 to rotate forward, and the second rotating shaft 31 drives the insulation layer 33 to unfold along the support rod 11; if the internal temperature is still lower than the set threshold, the shading net 25 is deployed, and an air insulation layer is formed between the shading device 2 and the insulation device 3 directly below it. This structure can effectively block the direct exchange of heat between indoors and outdoors, inhibit heat conduction and heat convection, and significantly reduce heat transfer efficiency, thereby achieving excellent heat preservation effect. When the temperature is detected to be higher than the set threshold, the insulation layer 33 is rolled up: the insulation motor 32 drives the second rotating shaft 31 to rotate in the opposite direction, and the insulation layer 33 is rolled up along the support rod 11 onto the second rotating shaft 31.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
