Description

Technical Field

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

[0002] In the horticulture industry, traditional rain shelters are closed structures, which can negatively impact ventilation and photosynthesis in plants on sunny days, offering limited protection. This has led to the development of self-closing protective shelters. However, these shelters require the protective film to be pulled from one side of the shelter to the other, making it impossible to adjust light transmittance according to crop growth. Furthermore, the entire protective film needs to be replaced when damaged. This is particularly problematic for potted roses, pothos, spider plants, peace lilies, and lucky bamboo. These plants require the outer covering to be removed in the morning to allow sunlight into the shelter, raising the temperature. Around noon, the bottom and top protective films are opened to ventilate and reduce humidity, promoting healthy plant growth. While existing shelters can be automated, most only remove the covering and protective film at once, failing to open the film at specific locations as needed, requiring manual adjustments by staff, significantly increasing workload. Therefore, we propose a new type of horticultural protective shelter. Summary of the Invention

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.

[0039] Example 1

[0040] Please see Figure 1-12 The present invention provides a technical solution:

[0041] A garden flower protection shed includes a main body 1 and fixed frames 10 respectively set at the front and rear ends of the main body 1. The main body 1 and fixed frames 10 are common existing structures, which will not be described in detail here. It also includes mounting frames 11. Multiple mounting frames 11 are provided. Multiple mounting frames 11 are movably set on the main body 1, and each mounting frame 11 is provided with a cotton quilt layer. Multiple mounting frames 11 are respectively set on the east side, top and west side of the main body 1. In the morning, the mounting frames 11 on the east side and top are opened first, while the mounting frames 11 on the west side are not opened. This can further ensure that the temperature inside the main body 1 is increased. It should be noted that the east side in this solution refers to the side where the sun rises first. This side will be exposed to sunlight first, which will increase the temperature inside the main body 1.

[0042] The progressive start-up unit 2 is mounted on the fixed frame 10 and is used to control the mounting frame 11 located on the east side and top to open first, and the mounting frame 11 located on the west side to open later, so as to ensure the temperature inside the body 1.

[0043] The progressive start-up unit 2 includes multiple spindles 21 that are rotatably disposed between two fixed frames 10. Mounting frames 11 are respectively disposed on adjacent spindles 21. The fixed frames 10 are provided with a transmission assembly 3 for driving the multiple spindles 21 to rotate. The fixed frames 10 are provided with a delay member 4 for controlling the opening of the mounting frame 11 located on the west side. The fixed frames 10 are provided with a positioning seat 22. The positioning seat 22 is provided with a locking member 5 connected to any spindle 21 for driving the spindle 21 to be locked and positioned in real time.

[0044] The transmission assembly 3 includes a transmission shaft 31 and a transmission shaft 32 rotatably mounted on the fixed frame 10. The transmission shaft 31 and the transmission shaft 32 are located at the east side and top corner of the main body 1. The transmission shaft 31 and the transmission shaft 32 are equipped with a transmission gear 33 for mutual use. The main shaft 21, the transmission shaft 31 and the transmission shaft 32 are all equipped with a pulley 34. A synchronous belt 35 is provided between the pulley 34 on the east side and the pulley 34 on the transmission shaft 31. A synchronous belt 36 is provided between the pulley 34 on the top and the pulley 34 on the transmission shaft 32. A synchronous belt 37 is provided between the pulley 34 on the west side.

[0045] The delay component 4 includes a connecting shaft 41 and a connecting shaft 42 rotatably mounted on a fixed frame 10. The connecting shaft 41 and the connecting shaft 42 are located at the west side and top corner of the main body 1. The connecting shaft 41 and the adjacent main shaft 21 at the top are each equipped with a pulley 43. A synchronous belt 44 is provided between the two pulleys 43. A half gear 45 is provided on the connecting shaft 41. An input gear 46 that meshes with the half gear 45 is provided on the connecting shaft 42. An output gear 47 is provided on the main shaft 21 located on the west side. A connecting shaft 48 is rotatably mounted on the fixed frame 10. A reversing gear 49 that meshes with the input gear 46 and the output gear 47 is provided on the connecting shaft 48. The number of teeth of the reversing gear 49 is the same as the number of teeth of the output gear 47. The number of teeth of the input gear 46 is greater than the number of teeth of the output gear 47. This tooth arrangement makes the rotation angle of the mounting frame 11 located on the west side greater than the rotation angle of the mounting frame 11 located on the east side and the top during subsequent rotation.

[0046] The locking component 5 includes multiple springs 51 movably mounted on the positioning seat 22. Each spring 51 has a positioning ball 52 at its end. The positioning seat 22 has multiple mounting slots 53 for the movement of the springs 51 and the positioning balls 52. The main shaft 21 is provided with a circular plate 54. The circular plate 54 has slots 55 that cooperate with the multiple positioning balls 52.

[0047] Top-level active frame 12, the top-level active frame 12 is set at the top center of the main body 1;

[0048] There are two side movable frames 13, which are respectively movable on both sides of the main body 1;

[0049] The ventilation unit 6 is mounted on the fixed frame 10 and is used to control the side movable frames 13 located on both sides of the main body 1 to open first, and the top movable frame 12 located on the top of the main body 1 to open later, so as to ensure ventilation while preventing the temperature inside the main body 1 from dropping too quickly.

[0050] The ventilation unit 6 includes multiple rotating shafts 61 that are rotatably mounted on the fixed frame 10. The multiple rotating shafts 61 are respectively connected to the top movable frame 12 and the side movable frame 13. The fixed frame 10 is provided with an adjustment component 7 for driving the multiple rotating shafts 61 to rotate. The fixed frame 10 is provided with a connecting frame 62. The connecting frame 62 is provided with a control component 8 for controlling the top movable frame 12 to open.

[0051] The adjustment assembly 7 includes a mounting shaft 71 rotatably mounted on the fixed frame 10, the mounting shaft 71 being located at the east corner of the main body 1. Two mounting shafts 72 are rotatably mounted on the fixed frame 10 at the west corner of the main body 1. Both mounting shafts 72 are equipped with a transmission gear 73 that works in conjunction with each other. The rotating shaft 61, the mounting shaft 71, and the mounting shafts 72 are all equipped with pulleys 74. A transmission belt 75 is provided between the pulleys 74 located on the east side and the top, and a transmission belt 76 is provided between the pulleys 74 located on the west side.

[0052] The control component 8 includes a fixed shaft 81 rotatably mounted on the connecting frame 62, a pulley 74 located on the fixed shaft 81, a rotating rod 82 mounted on the fixed shaft 81, a fixed disk 83 mounted on the rotating shaft 61 connected to the top movable frame 12, and an arc-shaped groove 84 on the fixed disk 83 that cooperates with the rotating rod 82.

[0053] Fixed frame 14, multiple fixed frames 14 are provided, and multiple fixed frames 14 are respectively set on the body 1. The fixed frames 14, together with the top movable frame 12 and the side movable frame 13, protect the body 1. The top movable frame 12, the side movable frame 13 and the fixed frame 14 are all provided with protective film.

[0054] The switching unit 9 is mounted on the fixed frame 10 and connected to the progressive start-up unit 2 and the ventilation unit 6, and is used to control the operation of the progressive start-up unit 2 and the ventilation unit 6 respectively.

[0055] The switching unit 9 includes an electric push rod 91 mounted on a fixed frame 10. The end of the electric push rod 91 is provided with a mounting base 92. A drive motor 93 is mounted on the mounting base 92. An output shaft 94 is rotatably mounted on the mounting base 92. A drive gear 95 connected to the drive motor 93 is mounted on the output shaft 94. A driven gear 1 96 and a driven gear 2 97 are respectively mounted on the main shaft 21 and the rotating shaft 61 adjacent to the drive gear 95. The driven gear 1 96 and the driven gear 2 97 are used in conjunction with the drive gear 95.

[0056] In use, at dawn, the electric actuator 91 is in the initial position, which means that the drive gear 95 and the driven gear 96 mesh. The drive motor 93 starts and drives the output shaft 94 to rotate. The output shaft 94 drives the driven gear 96 to rotate through the drive gear 95. The driven gear 96 then drives the adjacent main shaft 21 to rotate. Under the action of the pulley 34, the timing belt 35, the timing belt 36, and the timing belt 37, multiple main shafts 21 rotate. However, due to the meshing of the two transmission gears 33, the main shaft 21 at the top is in the opposite direction to the main shaft 21 on the east side, which is more conducive to the entry of sunlight. Therefore, the half gear 45 is not meshed with the input gear 46 at this time, so the main shaft 21 on the west side does not rotate.

[0057] As the rotation continues, the main shaft 21 at the top and the main shaft 21 on the east side continue to rotate, and the main shaft 21 on the west side also rotates, and the rotation speed is faster. This ensures that more sunlight enters and the flowers grow better. At this point, the installation frame 11 is fully opened, the cotton quilt layer is also opened, and the most sunlight enters the main body 1.

[0058] Then at noon, the electric actuator 91 drives the mounting base 92 to move. After the mounting base 92 moves, the drive gear 95 meshes with the driven gear 97. The drive motor 93 starts and drives the output shaft 94 to rotate. The output shaft 94 drives the driven gear 97 to rotate through the drive gear 95. The driven gear 97 then drives the adjacent rotating shaft 61 to rotate. Under the drive of the pulley 74 on the rotating shaft 61, the mounting shaft 71, and the mounting shaft 72, multiple rotating shafts 61 rotate synchronously. However, due to the setting of the two transmission gears 73, the rotation direction of the rotating shaft 61 on the west side is opposite to the rotation direction of the rotating shaft 61 on the east side and the top.

[0059] When the rotating shaft 61 on the west side initially rotates, because the fixed plate 83 has an arc-shaped groove 84, the rotating rod 82 rotates within the arc-shaped groove 84. The fixed shaft 81 will not drive the rotating shaft 61 connected to the top movable frame 12 to rotate synchronously. Only when the rotating rod 82 rotates to the end of the arc-shaped groove 84 will it drive the fixed plate 83 and the rotating shaft 61 to rotate together, thereby opening the top movable frame 12. Thus, after a single use, the reverse operation can be used to reset each structure for the next use.

[0060] Example 2

[0061] Please see Figure 1 and 13 The present invention provides a technical solution:

[0062] Unlike Embodiment 1, the mounting frame 11 is equipped with a reflector 15 on the side near the main body 1. Through the reflection of light, the temperature inside the main body 1 can be further increased from early morning to noon. At the same time, it also has the advantage of increasing the light area, which is more conducive to the growth of flowers.

[0063] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
