Description

Technical Field

[0001] The invention relates to the technical field of cultivation devices, in particular to a phototropic mobile cultivation device suitable for a solar greenhouse. Background Art

[0002] Traditional cultivation methods mainly rely on soil cultivation, which has many limitations. First, soil conditions are crucial to crop growth, but soil conditions in different regions and seasons vary greatly, making it difficult to meet the optimal needs of crop growth. Second, water shortage and waste are becoming increasingly serious problems, and traditional irrigation methods are difficult to achieve precise irrigation, resulting in inefficient water resource utilization. In addition, uneven light distribution is also one of the important factors affecting crop growth. Light conditions in fixed locations limit the growth potential and yield of crops.

[0003] In order to solve the limitations of traditional cultivation methods, mobile cultivation devices came into being. This device can move freely within a certain range through mechanical transmission and intelligent control, thereby optimizing the use of environmental factors such as light, temperature, and humidity. The mobile cultivation device not only improves the utilization rate of land and space resources, but also enhances the adaptability and growth potential of crops to the environment.

[0004] Some greenhouses are built on the mountainside, which can make full use of this land resource and improve land use efficiency. At the same time, the mountainside is relatively sheltered from the wind, which can reduce the damage of strong winds to the greenhouses. However, due to the blocking of light by the surrounding mountains, some parts of the greenhouse may not receive light in the morning or afternoon, and the strong sunlight at noon can easily cause damage to the plants. At the same time, due to the high geographical location and low light angle, different cultivation devices may be blocked, and the vertical space utilization rate is low. Summary of the invention

[0011] The second tilting mechanism tilts the cultivation pool perpendicularly to the tilting direction under the action of the first tilting mechanism, so that the cultivation pool is perpendicular to the altitude angle of sunlight, so that the cultivation pool can be evenly irradiated with sunlight.

Two motors 3 17 are installed on the fixed rod 15 to drive the two screw rods 2 16 to rotate.

[0054] As an embodiment of the present invention, a tooth groove 211 is provided at the bottom of the short side of one side of the support frame 21, and one side of the slider 2 12, the slider 3 13, and the slider 4 14 are rotatably connected to two pulleys 18, and the two pulleys 18 are respectively located at the two ends of the slider 2 12, the slider 3 13, and the slider 4 14, and a belt 19 is sleeved on the two pulleys 18.

[0056] As an embodiment of the present invention, a plurality of light-sensitive sensors 7 are provided and evenly installed on the surface of the greenhouse.

[0058] As an embodiment of the present invention, the sun shadow algorithm includes the sun altitude angle a=arcsin(sinφsinδ+cosφcosδcosω);

[0059] Solar azimuth b = arcsin (cosδsinω / cosa);

[0060] The projection of sunlight on the ground is L=h1 / tana.

[0061] Embodiment 1

[0062] like Fig. 9 As shown, a track 6 is installed in the greenhouse, and a plurality of cultivation devices are installed on the longitudinal track 62. The cultivation devices are moved transversely by moving the longitudinal track 62 on the transverse track 61, and the cultivation devices are moved longitudinally by rotating the roller 113 on the longitudinal track 62. Fig.10 As shown, a photosensitive sensor 7 is installed at a certain distance on the surface of the greenhouse. When the photosensitive sensor 7 receives a light signal, the entire greenhouse adjustment system is started. A photoelectric position sensor 114 is installed on the frame 1. Fig.11 As shown, when part of the light is irradiated on the photoelectric position sensor 114, the position of the incident light on the photoelectric position sensor 114 can be determined. When a part of the cultivation device cannot be irradiated by the light, the photosensitive layer of the photoelectric position sensor 114 does not receive the light completely. At this time, the greenhouse adjustment system records the position of the photoelectric position sensor 114, and moves the cultivation device through the roller 113 and the longitudinal rail 62 to move it from the shadow to the illuminated position until the photoelectric position sensor 114 receives the light completely.

[0063] In order to facilitate the calculation of light irradiation and shadow, the cultivation devices in the front and rear rows are A1, A2, and A3 respectively, the cultivation devices in the left and right rows are B1, B2, and B3 respectively, and the upper and lower three-layer cultivation pools 4 are C1, C2, and C3 respectively;

[0064] Due to the high geographical location and low light angle, different cultivation devices may be blocked, such as Figure 8 , Fig.11 , Fig.12 As shown, the irradiation angle of the sun is the solar altitude angle a. In order to prevent A1, A2, A3; B1, B2, B3 from blocking each other, the edge of the shadow irradiated by the sun needs to be located at the bottom of the cultivation device. Assume:

[0065] The distance between A1, A2, and A3 is D1, the distance between B1, B2, and B3 is D2, and the height of the cultivation device is h1;

[0066] Calculation method based on the projection of sunlight on the ground: Fig.13 As shown, a pole is inserted vertically into the ground to ensure that it is stable and immovable. The position of the bottom of the pole is marked on the ground as the starting point of the projection. The shadow of the pole is observed and its length is measured. In this embodiment, the length of the pole is the height of the cultivation device. It can be known that the projection of sunlight rays on the ground is L = h1 / tana;

[0067] Where a is the solar altitude angle. According to the solar altitude angle formula a=arcsin(sinφsinδ+cosφcosδcosω), φ is the local latitude, which the system can query by itself according to the positioning; δ is the solar declination angle; ω is the hour angle, which the system can obtain by inputting the local date and time according to the online version of the daily calendar.

[0068] like Fig.12 As shown, when observed from a bird's-eye view, since the sun's rays will deviate to the east or west, and the angle of deviation is the solar azimuth b, the projection L of the sunlight on the ground in the front-back direction and the left-right direction are D1=Lcosb and D2=Lsinb respectively; where the solar azimuth b=arcsin(cosδsinω / cosa).

[0069] Therefore, it is only necessary to make the distances between the front, back, left and right of the cultivation device equal to the distances D1 and D2 of the projections L of the sunlight on the ground in the front and back directions and the left and right directions to avoid mutual shading among A1, A2, A3, B1, B2, and B3.

[0070] Among them, a is the solar altitude angle; b is the solar azimuth angle; D1 is the distance between A1, A2, and A3; D2 is the distance between B1, B2, and B3; h1 is the height of the cultivation device; φ is the local latitude; δ is the solar declination angle; ω is the hour angle; and L is the projection of sunlight on the ground.

[0071] Embodiment 2

[0072] In order to increase the utilization rate of the vertical space, the cultivation device is provided with multiple cultivation pools 4. As the illumination altitude angle increases, C1, C2, and C3 may block each other. At this time, the illumination area in the greenhouse is large, and the distribution space of the cultivation device is large. Therefore, by moving C2 and C3 horizontally, the illumination range can be increased without affecting the illumination between multiple cultivation devices. Fig.14 As shown, suppose:

[0073] The distance between C1, C2, and C3 is h2, the distance that C2 moves horizontally to the left is d1, and the distance between the illumination point on C2 and C3 and the shielding point on C1 is l-d1. It can be seen from the figure that the distance between the illumination point and the shielding point is the projection of the sunlight on the ground, so:

[0074] l-d1=Lcosb

[0075] L=h2 / tana

[0076] a=arcsin(sinφsinδ+cosφcosδcosω)

[0077] b = arcsin(cosδsinω / cosa)

[0078] Therefore, it is only necessary to move C2 to the left by d1 and to move C3 by 2d1 so that C1 and C2 are within the illumination range to avoid mutual shading among C1, C2 and C3.

[0079] Among them, a is the solar altitude angle; b is the solar azimuth angle; h2 is the distance between C1, C2, and C3; d1 is the distance that C2 moves horizontally to the left; φ is the local latitude; δ is the solar declination angle; ω is the hour angle; L is the projection of sunlight on the ground, and l is the width of the cultivation pool 4.

[0080] Specific movement methods such as Figure 4-7 As shown, first Figure 5 , Figure 6 As shown, the starting motor 111 drives the gear 110 to rotate. Because the gear 110 and the pulley 18 are coaxially fixedly connected, and the two pulleys 18 are connected by the belt 19, when one pulley 18 rotates, the two gears 110 are driven to rotate at the same time, so that the support frame 21 can move to the edge of the slider 2 12, thereby increasing the travel of the support frame 21. At the same time, the gears 110 at both ends can drive the support frame 21 to move to both sides; similarly, Figure 7 As shown, after the gear 110 on the driving slider 4 14 drives the support frame 21 to move the same distance, the motor 4 111 on the slider 3 13 is started, and the motor 4 111 is engaged with the tooth groove 2 112 on the slider 4 14 to drive the slider 4 14 and the support frame 21 to move the same distance again, thereby realizing the horizontal movement of the cultivation pool 4.

[0081] Embodiment 3

[0082] When the greenhouse space utilization rate is low, it is not suitable to increase the lateral area, so the illumination area is increased by increasing the vertical spacing of the cultivation pools 4, such as Fig.15 As shown, assuming that the distance that the cultivation pool 4 rises is d2, the distance between the illumination point and the shielding point is the width of the cultivation pool 4, therefore:

[0083] l=Lcosb

[0084] L=(h2+d2) / tana

[0085] a=arcsin(sinφsinδ+cosφcosδcosω)

[0086] b = arcsin(cosδsinω / cosa)

[0087] Therefore, it is only necessary to move C1 and C2 upward by d2 at the same time, and then move C1 upward by d2, so that C2 and C3 are within the illumination range, thereby preventing C1, C2, and C3 from blocking each other.

[0088] a is the solar altitude angle; b is the solar azimuth angle; h2 is the distance between C1, C2, and C3; d2 is the rising distance of the cultivation pool 4; φ is the local latitude; δ is the solar declination angle; ω is the hour angle; L is the projection of sunlight rays on the ground, and l is the width of the cultivation pool 4.

[0089] Specific movement methods such as Figure 1-2 As shown, two motors 3 17 are started simultaneously to drive two screw rods 2 16 to rotate. Since the slider 1 11 and the slider 2 12 are threadedly connected to the two screw rods 2 16 and are slidably connected to the frame 1, the two cultivation pools 4 on the upper layer first move a distance, and then only the upper motor 3 17 is started to drive one screw rod 2 16 to rotate, so that the uppermost cultivation pool 4 moves the same distance again.

[0090] Embodiment 4

[0091] Because the strong sunlight at noon can easily cause damage to plants, such as Figure 1 , Figure 3 As shown, by starting the driving roller 118, it pulls the rolling curtain 116 through the guide rod 117 to block C1 and avoid sunlight exposure; Fig.16 As shown, by moving C2 and C3 horizontally, C3 is located on the right side of the shielding point of C2, and C2 is located on the right side of the shielding point of C1, thereby preventing C2 and C3 from being exposed to sunlight. Assume:

[0092] The distance C2 moves horizontally to the left is d3. From the figure, we can see that the distance between the illumination point and the occlusion point is d3, so:

[0093] d3=Lcosb

[0094] L=h2 / tana

[0095] a=arcsin(sinφsinδ+cosφcosδcosω)

[0096] b = arcsin(cosδsinω / cosa)

[0097] Therefore, it is only necessary to move C2 and C3 by d3 and 2d3 respectively to avoid sunlight exposure, thereby reducing the complexity of shading the multi-layer cultivation pool 4.

[0098] Among them, a is the solar altitude angle; b is the solar azimuth angle; h2 is the distance between C1, C2, and C3; d3 is the distance that C2 moves horizontally to the left; φ is the local latitude; δ is the solar declination angle; ω is the hour angle; L is the projection of sunlight on the ground, and l is the width of the cultivation pool 4.

[0099] The specific moving method is the same as that of the second embodiment.

[0100] Embodiment 5

[0101] In order to make the plants perpendicular to the sunlight and increase the lighting area of ​​the plants, the following is achieved by making the plants perpendicular to the solar altitude angle and solar azimuth angle:

[0102] The sun altitude angle is:

[0103] a=arcsin(sinφsinδ+cosφcosδcosω)

[0104] The solar azimuth is:

[0105] b = arcsin(cosδsinω / cosa)

[0106] Among them, φ is the local latitude; δ is the solar declination angle; ω is the hour angle.

[0107] like Figure 4 As shown, the motor 1 24 is started to drive the screw rod 1 22 to rotate. Since one end of the moving block 25 is threadedly connected to the screw rod 1 22, and the other end is slidably connected to the slide rod 23, the screw rod 1 22 rotates to drive the moving block 25 to move toward the center of the long side of the fixed frame 31, so that one end of the connecting rod 1 26 moves with the moving block 25. Since the length of the connecting rod 1 26 remains unchanged, and the other end of the connecting rod 1 26 is rotatably connected to one end of the connecting rod 27 through the connecting shaft 1 28, the connecting shaft 1 28 moves upward. At the same time, the other end of the fixed frame 31 is fixed by the tripod 29 and the rotating shaft 2 210, so that the fixed frame 31 and one end of the cultivation pool 4 are lifted to form a certain angle until they are perpendicular to the solar azimuth angle; then the motor 2 33 is started to drive the rotating shaft 3 32 to rotate, and the rotating shaft 3 32 drives the cultivation pool 4 to rotate together until it is perpendicular to the solar altitude angle.
