Description

Technical Field

[0001] The utility model relates to the technical field of sunshade devices, in particular to a frame structure of a sunshade device. Background Art

[0002] Light is a necessary component for crops to carry out photosynthesis, but the demand for light by plants is not unlimited. Excessive light will lead to excessive evaporation of crop water, affecting the growth of crops. Take ginseng as an example. When the light intensity is lower than 400 lux, the photosynthesis rate of ginseng increases significantly with the increase of light intensity. When the light intensity is higher than 400 lux, the photosynthesis rate of ginseng slows down significantly with the increase of light intensity. In addition, when the light is too strong, the ginseng plants will become short, with thick leaves and yellowish color. In order to control the light intensity of crops, farmers will set up sunshade devices for crops during parts of the day when the light intensity is high.

[0003] Existing sunshade devices mostly include a frame and a sunshade net. The sunshade net is placed and lifted manually or electrically. The manual method is too laborious, the electric method is too expensive, and the frequent movement of the sunshade net will reduce the service life of the sunshade net.

[0004] Existing shading devices also use shading nets that are distributed at intervals, and use the changes in the direction of sunlight to achieve the goal of sunlight irradiating different areas at different times. Since crops receive sunlight at different times, there are significant differences in the state of crops, air temperature and humidity, which will lead to significant differences in the growth state of crops in different areas, affecting the crop yield.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] Combination Figures 1 to 5 As shown, a frame structure of a sunshade device provided by the utility model includes a sunshade component 1 and a support component 2.

[0032] Combination Figures 1 to 5 As shown, the sunshade assembly 1 includes an inclined rod 11 and a cross rod 12, and the inclined rod 11 and the cross rod 12 are connected end to end to form a rectangle, and one end of the sunshade assembly 1 is tilted upward at a specific angle toward the direction of the rising sun; the support assembly 2 includes a first support rod 21 and a second support rod 22, and the first support rod 21 and the second support rod 22 are tilted back to back and fixed on the mounting surface, and the support assembly 2 is fixedly connected to the sunshade assembly 1; the first support rod 21 and the second support rod 22 have the same inclination angle on the mounting surface, and the fixed points of the first support rod 21 and the second support rod 22 on the mounting surface are 18 unit lengths apart, and the connection points of the first support rod 21 and the second support rod 22 on the sunshade assembly 1 are 25 unit lengths apart, the length of the first support rod 21 is 30 unit lengths, and the length of the second support rod 22 is 20 unit lengths.

[0033] In the present embodiment, by designing the shape angle and facing direction of the sunshade component and utilizing the change in sunlight radiation direction, the angle between the sunlight radiation direction and the sunshade net changes in the morning and afternoon. The angle between the sunlight radiation direction and the sunshade net in the morning tends to 0 degrees, and the sunshade effect of the sunshade net is low. The angle between the sunlight radiation direction and the sunshade net in the afternoon tends to 90 degrees, and the sunshade effect of the sunshade net is high, so that sunlight directly shines on crops only in the morning. The shape and size of the inclined rod 11, the first support rod 21 and the second support rod 22 are designed, and a specific shape angle of the sunshade component is achieved through a complete dimensional relationship.

[0034] In this embodiment, the inclination angle of the specific sunshade component is a non-integer angle. This special angle is not easy to achieve accurately during the production and installation process. The non-integer specific angle is achieved through the integer size relationship, which not only facilitates production and processing, but also makes the product angle more precise.

[0035] In some embodiments, the angle between the direction facing the head-up end of the sunshade assembly 1 and the direction of the rising sun is less than 45 degrees. Since the working effect of the sunshade assembly 1 is strongly related to the sun's radiation angle, the frame structure of the sunshade device controls the change of the sun's radiation effect by designing the head-up angle. When the angle between the direction facing the head-up end of the sunshade assembly 1 and the direction of the rising sun is too large, the head-up angle of the sunshade assembly 1 will lose its effect.

[0036] In this embodiment, since the direction of sunlight changes in the four seasons, the sun rises from the northeast in summer and from the east in spring and autumn. The smaller the angle between the sunshade assembly 1 and the direction of sunlight, the larger the projection of the sunshade assembly 1 in the direction of sunlight and the better the shading effect. In view of the highest light intensity in summer, the head end of the sunshade assembly 1 should face north to northeast to ensure the working effect of the sunshade assembly 1. The direction of the head end of the sunshade assembly 1 can be appropriately adjusted in combination with the lighting requirements of crops. The lower the lighting requirements of crops, the more the head end of the sunshade assembly 1 is biased towards the northeast to improve the shading effect. The above content is mainly for crops grown in summer, such as ginseng, etc. When greenhouse planting is used or the crops have special habits, the direction of the head end of the sunshade assembly 1 should be adjusted according to the growth time of the plants.

[0037] In some embodiments, in combination Figure 5 As shown, the sunshade assemblies 1 are evenly distributed along the direction of the horizontal bar 12, and the adjacent sides of the adjacent sunshade assemblies 1 share the diagonal bars 11 and the supporting assemblies 2. In order to cover the length of the farmland, it is necessary to add a splicing or extension design to the sunshade assemblies 1. The shared diagonal bars 11 and the supporting assemblies 2 can effectively reduce the consumption of raw materials and reduce costs.

[0038] In some embodiments, in combination Figure 4As shown, the sunshade components 1 are evenly distributed along the direction of the diagonal rod 11, and the translation distance between adjacent sunshade components 1 is equal to the length of the diagonal rod 11. Since the sunshade components 1 have a head-up angle design in this direction, simple splicing cannot be used. If the distance between adjacent sunshade components 1 is too large, the sunshade components 1 will not be able to cover the farmland in the afternoon, and if the distance between adjacent sunshade components 1 is too small, the sunshade components 1 will cover too much in the morning. The translation distance between adjacent sunshade components 1 is equal to the length of the diagonal rod 11, which can ensure that when the sun rises directly above, the shadow of the sunshade component 1 can fully cover the farmland, and sufficient front and rear spacing can increase the ventilation effect.

[0039] In some embodiments, in combination Figure 2 As shown, the sunshade assembly 1 also includes auxiliary diagonal rods 13, which are evenly distributed between the diagonal rods 11, and both ends of the auxiliary diagonal rods 13 are fixedly connected to the cross rods 12. The auxiliary diagonal rods 13 mainly play an auxiliary supporting role, which improves the overall strength of the sunshade assembly 1 and can also effectively support the sunshade net, sun visor, etc. that are covered on the sunshade assembly 1 later.

[0040] In some embodiments, the frame structure of the sunshade device also includes a sprinkler pipe, which is fixedly connected to the inclined rod 11 and the auxiliary inclined rod 13. Pesticides, irrigation water, etc. can be introduced into the sprinkler pipe. At the same time, the connection points of the sprinkler pipe and the inclined rod 11 and the auxiliary inclined rod 13 are designed at the connection points of the inclined rod 11, the auxiliary inclined rod 13 and the support assembly 2. The support strength here is the highest, which is beneficial to reducing the impact of the sprinkler pipe on the frame structure of the sunshade device, and the sufficient height is beneficial to improve the coverage range.

[0041] In some embodiments, in combination Figure 1 As shown, the support assembly 2 also includes a fixed buried rod 23, which is integrally formed and connected to one end of the mounting surface connecting the first support rod 21 and the second support rod 22, and the fixed buried rod 23 is buried in the mounting surface. The fixed buried rod 23 is buried in the mounting surface to provide good support, and the buried rod mouth can be arranged in advance through measurement, which greatly speeds up the installation speed of the frame structure of the sunshade device in the later stage.

[0042] In some embodiments, in combination Figure 1 As shown, the minimum length of the fixed buried rod 23 is 6 unit lengths. Ensuring the length of the fixed buried rod 23 means ensuring the supporting effect of the fixed buried rod 23.

[0043] In some embodiments, in combination Figure 1 , 2As shown, the support assembly 2 also includes a support cross bar 24, the number of the support cross bars 24 is 2, the first support bar 21 and the second support bar 22 are respectively fixedly connected as a whole through the support cross bars 24, and after the support cross bars 24 are added, the sunshade assembly 1 and the support assembly 2 can be assembled to form a reinforced structure, thereby increasing the overall strength of the frame structure of the sunshade device.

[0044] In some embodiments, the sunshade assembly 1 is covered with a sunshade net, and the main effect of the sunshade net is to reduce the intensity of sunlight. The sunshade net is mainly aimed at the growth needs of ginseng. The sunshade net here can also refer to a plate-shaped sunshade.

[0045] Working process: One end of the sunshade assembly 1 is tilted upward at a specific angle toward the direction of the rising sun and is set above the crops. In the morning, the angle between the sunlight direction and the sunshade assembly 1 changes as follows: first it decreases to 0 and then increases upward. The angle is always maintained within a small range. The smaller the angle, the smaller the projection of the sunshade assembly 1 in the sunlight direction, and the worse the shading effect.

[0046] In the afternoon, the angle between the sunlight direction and the sunshade assembly 1 changes as follows: first it increases to 90 and then decreases downward, and the angle always remains within a larger range. The larger the angle, the larger the projection of the sunshade assembly 1 in the sunlight direction, and the better the sunshade effect.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
