Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of planting greenhouse, especially a kind of agricultural planting greenhouse with adjustable light intensity. BACKGROUND

[0002] In the field of agricultural planting greenhouse, the adjustment of light intensity is crucial for crop growth. In existing greenhouse technology, light adjustment mainly relies on selecting appropriate light-transmitting materials, adjusting greenhouse structure, using shading nets or reflective films, etc. For example, using drip-free film, anti-aging film, and frequently cleaning the film surface to improve light transmission; adjusting roof angle, reducing skeleton shading, etc. to optimize light conditions; using reflective materials such as aluminum plate, aluminum foil or silver-gray reflective film to increase light intensity. However, these methods have certain limitations, as they cannot accurately control light intensity, and the adjustment of light intensity is not flexible enough in different seasons and weather conditions. Moreover, in actual use, it is difficult to distribute light evenly throughout the greenhouse, resulting in light dead angles and affecting plant growth.

[0003] Therefore, there is an urgent need for an agricultural planting greenhouse with adjustable light intensity. SUMMARY

[0004] To solve the problem of inaccurate and flexible light adjustment in existing technology, and to solve the problem of light dead angles in the greenhouse affecting plant growth, the utility model provides an agricultural planting greenhouse with adjustable light intensity.

[0005] The technical solution of the utility model is as follows:

[0006] An agricultural planting greenhouse with adjustable light intensity, comprising a greenhouse main body and a roof located at the upper part of the frame main body, the roof comprises a rectangular outer frame connected to the top of the greenhouse main body, and a light-transmitting plate is arranged inside the rectangular outer frame;

[0007] It also includes an adjusting mechanism located below the light-transmitting plate, which adjusts the light intensity passing through the light-transmitting plate. The adjusting mechanism includes a light dispersion assembly, which includes a light-transmitting shell, a deformation air bag made of light-transmitting film is embedded in the middle of the light-transmitting shell, a light-transmitting liquid is filled in the deformation air bag, the light-transmitting shell and the deformation air bag form a concave lens structure as a whole, and a liquid injection pipe is connected to the deformation air bag on one side of the light-transmitting shell and extends to the outside of the greenhouse main body. The liquid injection pipe is used to fill the light-transmitting liquid in the deformation air bag to deform the deformation air bag, and then adjust the concave curvature of the concave lens structure formed by the light-transmitting shell and the deformation air bag as a whole.

[0008] Based on the above scheme, the light intensity passing through the light-transmitting plate is accurately adjusted by setting the light-transmitting plate and the adjusting mechanism on the greenhouse roof. Specifically, the light dispersion assembly in the adjusting mechanism includes a light-transmitting shell and a deformation air bag, and the light-transmitting shell and the deformation air bag form a concave lens structure as a whole, and the deformation air bag is filled with a light-transmitting liquid. Therefore, when natural light passes through the concave lens formed by the light-transmitting shell and the deformation air bag, the light can be dispersed to make the light evenly dispersed in the greenhouse and irradiate the plants in the greenhouse, thereby avoiding the occurrence of light dead angles and affecting the normal growth of the plants. It should be further pointed out that in the present scheme, the deformation air bag is made of a light-transmitting film and filled with a light-transmitting liquid. Therefore, by filling or extracting the light-transmitting liquid into or from the deformation air bag through the liquid injection pipe, the shape and curvature of the air bag can be changed, and the curvature of the concave lens is flexibly adjusted to accurately adjust the light intensity and adapt to the light requirements of the plants in different seasons and weather conditions. That is to say, when the light intensity needs to be increased, the light-transmitting liquid is filled into the deformation air bag through the liquid injection pipe to make the air bag expand, the curvature of the concave lens decreases, the light dispersion degree decreases, and the light intensity increases. Conversely, when the light intensity needs to be reduced, part of the light-transmitting liquid is extracted to make the air bag contract, the curvature of the concave lens increases, the light dispersion degree increases, and the light intensity decreases.

[0009] Preferably, the adjusting mechanism further comprises a light-shielding assembly, the light-shielding assembly comprising a light-shielding curtain and a driving mechanism, the light-shielding curtain being laid parallel between the light-transmitting shell and the roof, and the driving mechanism comprising a traction machine and a winding mechanism, the traction machine and the winding mechanism being respectively located at the two ends of the length direction of the light-shielding curtain.

[0010] Based on the above scheme, it should be pointed out that the adjusting mechanism of the present scheme not only includes the light dispersion assembly, but also adds the light-shielding assembly. That is to say, when the light is too strong, it may have adverse effects on the plants in the greenhouse. Therefore, the present scheme controls the unfolding and winding of the light-shielding curtain through the driving mechanism to shield or transmit the light entering the greenhouse, so as to further adjust the light intensity and avoid the light being too strong to irradiate into the greenhouse and affect the growth of the plants.

[0011] Further preferably, parallel sliding rails are further provided on both sides of the width direction of the light-shielding curtain, and a connecting sliding rod is further connected between the two parallel sliding rails, and the connecting sliding rod is provided at the position where the light-shielding curtain is connected with the traction machine. By providing the parallel sliding rails and the connecting sliding rod, the traction machine can move the light-shielding curtain by pulling it.

[0012] Specifically, the winding mechanism comprises a winding roller and a winding motor, the winding roller is installed on the inner side of the greenhouse body through a mounting frame, the length direction of the winding roller is parallel to the width direction of the shading curtain, one side of the winding roller is connected with the tail end of the shading curtain, and the winding motor is located at one end of the winding roller and connected with the winding roller through an output end.

[0013] Based on the above scheme, the winding roller is rotated by the rotation of the winding motor, so that the winding of the shading curtain is realized, that is, when the winding motor starts to work and rotates, the traction machine does not work, so that the winding roller is rotated after the winding motor rotates, so that the shading curtain is wound up, and light can enter the greenhouse through the light-transmitting shell.

[0014] Further, the output end of the traction machine is connected with the connecting slide rod through a traction steel wire rope. By arranging the traction machine, when it is needed to block the light entering the greenhouse, the traction machine is started, and the winding motor is turned off, so that the connecting slide rod moves on the parallel slide rail by the traction steel wire rope after the traction machine works, and then the shading curtain is unfolded, so that the light entering the greenhouse is blocked, and the adverse effect of excessive light on the growth of plants is avoided.

[0015] Further preferably, a plurality of light-transmitting holes are formed in the shading curtain. By arranging the light-transmitting holes, sufficient light for the growth of plants can enter the greenhouse when the shading curtain is blocked, so that the growth of plants is ensured.

[0016] The beneficial effects of the utility model are as follows:

[0017] The present scheme realizes the accurate adjustment of the light intensity passing through the light-transmitting plate by arranging the light-transmitting plate and the adjusting mechanism on the greenhouse roof. Specifically, the light dispersion assembly in the adjusting mechanism comprises a light-transmitting shell and a deformation air bag, the light-transmitting shell and the deformation air bag form a concave lens structure as a whole, and the deformation air bag is filled with a light-transmitting liquid. Therefore, when natural light passes through the concave lens formed by the light-transmitting shell and the deformation air bag, the light can be dispersed, so that the light is uniformly dispersed in the greenhouse, the plants in the greenhouse are irradiated comprehensively, and the light dead angle is avoided, so that the normal growth of plants is affected.

[0018] Meanwhile, it needs to be further explained that, in the scheme, the deformation air bag is made of light-transmitting film, and is filled with light-transmitting liquid, so that the shape and curvature of the air bag can be changed by filling or extracting the light-transmitting liquid into the deformation air bag through the liquid injection pipe, and then the curvature of the concave lens is flexibly adjusted, so that the light intensity is accurately adjusted, and the light illumination requirement of the plants in different seasons and weather conditions is met, that is, when the light intensity needs to be increased, the light-transmitting liquid is filled into the deformation air bag through the liquid injection pipe, so that the air bag is inflated, the curvature of the concave lens is reduced, the light divergence degree is reduced, and the light intensity is increased; on the contrary, when the light intensity needs to be reduced, part of the light-transmitting liquid is extracted, so that the air bag is contracted, the curvature of the concave lens is increased, the light divergence degree is increased, and the light intensity is reduced.

DETAILED DESCRIPTION

[0025] The embodiments of the utility model will be further described below in combination with the drawings.

[0026] Embodiment:

[0027] As shown in Figure 1 and Figure 3 , a light intensity adjustable agricultural planting greenhouse, comprising a greenhouse main body 1 and a ceiling 2 located on the upper part of the frame main body, the ceiling 2 comprises a rectangular outer frame 20 connected with the top of the greenhouse main body 1, and a light-transmitting plate 21 is arranged in the rectangular outer frame 20;

[0028] Specifically, the adjusting mechanism is arranged below the light-transmitting plate 21, and the light intensity passing through the light-transmitting plate 21 is adjusted by the adjusting mechanism. The adjusting mechanism comprises a light dispersing assembly 3. The light dispersing assembly 3 comprises a light-transmitting shell 30. A deformation air bag 31 made of a light-transmitting film is arranged in the middle of the light-transmitting shell 30. The deformation air bag 31 is filled with a light-transmitting liquid. The light-transmitting shell 30 and the deformation air bag 31 form a concave lens structure as a whole. An injection pipe 32 is connected to the deformation air bag 31 and extends to the outside of the greenhouse main body 1. The injection pipe 32 is used to inject the light-transmitting liquid into the deformation air bag 31 to make the deformation air bag 31 deform, so as to adjust the concave curvature of the concave lens structure formed by the light-transmitting shell 30 and the deformation air bag 31 as a whole.

[0029] In Figure 1 , by arranging the light-transmitting plate 21 and the adjusting mechanism on the greenhouse roof 2, the light intensity passing through the light-transmitting plate 21 is accurately adjusted. Specifically, the light dispersing assembly 3 in the adjusting mechanism comprises the light-transmitting shell 30 and the deformation air bag 31. The light-transmitting shell 30 and the deformation air bag 31 form a concave lens structure as a whole. The deformation air bag 31 is filled with a light-transmitting liquid. Therefore, when the natural light passes through the concave lens formed by the light-transmitting shell 30 and the deformation air bag 31 as a whole, the light is dispersed (it is necessary to point out that the dotted arrow represents the natural light in Figure 1 . The light is uniformly dispersed in the greenhouse, so that the plants in the greenhouse are fully irradiated, thereby avoiding the light dead angle and affecting the normal growth of the plants.

[0030] It is further necessary to point out that, since the deformation air bag 31 in the embodiment is made of a light-transmitting film and is filled with a light-transmitting liquid, the shape and curvature of the air bag can be changed by injecting or extracting the light-transmitting liquid into or from the deformation air bag 31, so as to flexibly adjust the concave curvature of the concave lens, thereby accurately adjusting the light intensity and adapting to the light demand of the plants in different seasons and weather conditions. That is to say, when the light intensity needs to be increased, the light-transmitting liquid is injected into the deformation air bag 31 through the injection pipe 32, so that the air bag is inflated, the concave curvature of the concave lens is reduced, the light dispersion degree is reduced, and the light intensity is increased. Conversely, when the light intensity needs to be reduced, part of the light-transmitting liquid is extracted, so that the air bag is contracted, the concave curvature of the concave lens is increased, the light dispersion degree is increased, and the light intensity is reduced.

[0031] Based on the above embodiment, as a preferred, please refer to Figure 2The adjusting mechanism further comprises a light-shielding assembly 4, which comprises a light-shielding curtain 40 and a driving mechanism. The light-shielding curtain 40 is laid parallel between the light-transmitting shell 30 and the ceiling 2. The driving mechanism comprises a traction machine 41 and a winding mechanism 42, which are respectively located at the head and tail ends of the light-shielding curtain 40 in the length direction.

[0032] It should be noted that in the embodiment, the adjusting mechanism not only comprises the light-diffusing assembly 3, but also the light-shielding assembly 4. That is, when the light is too strong, it may have adverse effects on the plants in the greenhouse. Therefore, the present application controls the unwinding and winding of the light-shielding curtain 40 through the driving mechanism, so as to shield or transmit the light entering the greenhouse, so as to further adjust the light intensity, and avoid the light being too strong to irradiate into the greenhouse, which is not conducive to the growth of the plants.

[0033] Based on the above embodiment, specifically, Figure 2 it has been shown that parallel sliding rails 43 are further arranged on both sides of the light-shielding curtain 40 in the width direction, and a connecting sliding rod 44 is further connected between the two parallel sliding rails 43. The connecting sliding rod 44 is arranged at the position where the light-shielding curtain 40 is connected to the traction machine 41. Through the arrangement of the parallel sliding rails 43 and the connecting sliding rod 44, the traction machine 41 can move the light-shielding curtain 40 by pulling it.

[0034] As a further preferred embodiment, the winding mechanism 42 comprises a winding roller 420 and a winding motor 421. The winding roller 420 is mounted on the inner side of the greenhouse main body 1 through a mounting bracket. The length direction of the winding roller 420 is parallel to the width direction of the light-shielding curtain 40. One side surface of the winding roller 420 is connected to the tail end of the light-shielding curtain 40. The winding motor 421 is located at one end of the winding roller 420, and its output end is connected to the winding roller 420.

[0035] In specific implementation, the winding motor 421 drives the winding roller 420 to rotate, so as to realize the winding of the light-shielding curtain 40. That is, when the winding motor 421 starts to work and rotate, the traction machine 41 does not work. Therefore, after the winding motor 421 rotates, it drives the winding roller 420 to rotate, so as to wind up the light-shielding curtain 40, so that the light can enter the greenhouse through the light-transmitting shell 30.

[0036] Further, as a preferred implementation manner, the output end of the traction machine 41 is connected with the connecting slide rod 44 through a traction steel wire rope. Through the setting of the traction machine 41, when it is needed to shield the light entering the greenhouse, the traction machine 41 is started, and the winding motor 421 is closed, so that after the traction machine 41 works, the connecting slide rod 44 is pulled to move on the parallel slide rail 43 through the traction steel wire rope, and then the light shielding curtain 40 is unfolded, so that the light entering the greenhouse is shielded, and the light is prevented from being too strong to cause adverse effects on the growth of the plants.

[0037] As a further preferred implementation manner of the above embodiment, please refer to Figure 4 A plurality of light transmission holes 400 are further formed on the light shielding curtain 40.

[0038] It should be noted that through the formation of the light transmission holes 400, when the light shielding curtain 40 is used for shielding, sufficient light for the growth of the plants can also enter the greenhouse through the light transmission holes 400, and then the growth of the plants is ensured.

[0039] The above embodiment only expresses the specific implementation manner of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the patent range of the utility model. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection range of the utility model.
