Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a flexible photovoltaic bracket for agricultural-photovoltaic complementary use in which photovoltaic components can be stacked and stored. Background Art

[0002] As the installed capacity of photovoltaic power generation continues to increase, available land resources are becoming increasingly scarce, and the shortage of land resources has become a key factor restricting the development of the photovoltaic industry. In order to solve this problem, the agricultural photovoltaic complementary model came into being. It achieves efficient use of land resources by installing photovoltaic panels on agricultural land, but this model also faces challenges.

[0003] The shading effect of photovoltaic panels affects the crops' demand for sunlight, because in the traditional agricultural-photovoltaic complementary model, photovoltaic power generation often dominates, while agricultural needs are ignored, which makes it difficult to achieve balanced development of photovoltaics and agriculture.

[0004] The demand for sunlight for photosynthesis of plants is uneven at different time periods. During the growing season, plants have a high demand for sunlight, while during the dormant season, it is relatively less. In addition, during the day, the sunlight intensity at noon is often too high, exceeding the light saturation point of the plant, resulting in a decrease in photosynthesis efficiency. Plants may even experience a "lunch break phenomenon", that is, a decrease in photosynthesis rate.

[0005] The method of actively adjusting the position of photovoltaic panels is now adopted. According to the photosynthesis light demand of plants at different growth stages and at different times of the day, the position of photovoltaic panels is actively adjusted to control the light exposure time of plants, forming a power station operation strategy for composite use of light resources allocated by time, so that while the photovoltaic power station is operating to generate electricity, it does not affect or even promotes plant growth.

[0006] In addition, crops are easily affected by extreme weather such as hail, and it is urgent to solve the problem of how to protect crops from damage. Summary of the invention

[0038] Example 1

[0039] Reference Figure 1 to Figure 5 , which is the first embodiment of the present invention, provides a flexible photovoltaic support for agricultural-photovoltaic complementary use in which photovoltaic components can be stacked and stored, comprising:

[0040] The carrying mechanism 100 includes a column 101, an auxiliary component 102 adapted to be installed on the top of the column 101, and a receiving component 103 adapted to be installed on the top of the column 101;

[0041] The main body mechanism 200 includes a mounting component 201 adapted to be mounted on the outside of the auxiliary component 102 , and a sliding component 202 adapted to be mounted on the outside of the mounting component 201 .

[0042] Specifically, the auxiliary component 102 includes a crossbeam 102a fixedly connected to the top of the column 101, a limiting rod 102b fixedly connected to the outside of the crossbeam 102a, and a first support block 102c fixedly connected to the outside of the limiting rod 102b.

[0043] Furthermore, the auxiliary component 102 further includes a threaded rod 102d disposed outside the crossbeam 102a, a motor 102e adapted to be installed outside the crossbeam 102a, and a support assembly 102f adapted to be installed outside the threaded rod 102d;

[0044] The threaded rod 102d is fixedly connected to the output shaft of the motor 102e, and the output shaft of the motor 102e is rotatably connected to the interior of the crossbeam 102a.

[0045] Furthermore, the support assembly 102f includes a circular ring 102f-1 rotatably connected to the outside of the threaded rod 102d, and a second support block 102f-2 fixedly connected to the outside of the circular ring 102f-1.

[0046] Preferably, the containing component 103 includes a containing box 103a fixedly connected to the outside of the column 101, a mounting plate 103b fixedly connected to the outside of the containing box 103a, and a horizontal plate 103c slidably connected to the inside of the containing box 103a;

[0047] The first support block 102c and the second support block 102f-2 are both fixed on the outside of the mounting plate 103b.

[0048] It should be noted that the accommodating component 103 further includes a first spring 103d disposed outside the transverse plate 103c, a cavity 103e opened inside the accommodating box 103a, and a telescopic component 103f adapted to be installed inside the cavity 103e;

[0049] One end of the first spring 103d is fixedly connected to the outside of the transverse plate 103c, and the other end of the first spring 103d is fixedly connected to the inside of the containing box 103a.

[0050] In addition, the telescopic assembly 103f includes a cone block 103f-1 slidably connected inside the cavity 103e, and a second spring 103f-2 disposed outside the cone block 103f-1;

[0051] One end of the second spring 103f-2 is fixedly connected to the outside of the cone block 103f-1, and the other end of the second spring 103f-2 is fixedly connected to the inside of the cavity 103e.

[0052] It should be noted that a circular groove is provided on the outer side of the threaded rod 102d so that the circular ring 102f-1 can be arranged in the circular groove, thereby cooperating with the second support block 102f-2 to provide support force for the threaded rod 102d.

[0053] In order to prevent the circular ring 102f-1 from affecting the threaded sleeve that moves spirally on the outside of the threaded rod 102d, the maximum outer diameter of the circular ring 102f-1 shall not be greater than the depth of the thread groove on the outside of the threaded rod 102d.

[0054] Meteorological sensors and an information processing control center are arranged on the outside of the beam 102a, and soil sensors are arranged on the ground. The soil sensors are buried at the depth of the plant root crown underground to collect soil temperature and humidity. The meteorological sensors can collect plant photosynthesis indicators such as temperature, carbon dioxide concentration in the air, air humidity, and light intensity to provide data for the information processing control center.

[0055] According to the information detected by the meteorological sensor and the soil sensor, after the information processing control center analyzes and processes the amount of light required by the plant, the start and stop of the motor 102e can be controlled.

[0056] When the motor 102e is started, the threaded rod 102d can be driven to rotate by the output shaft of the motor 102e.

[0057] Example 2

[0058] Reference Figure 1 to Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that it provides a working state of the main mechanism 200.

[0059] Furthermore, the mounting component 201 includes a base 201a disposed outside the threaded rod 102d, a first inclined surface 201b opened outside the base 201a, and a second inclined surface 201c opened outside the base 201a.

[0060] Furthermore, the installation component 201 also includes a mounting groove 201d opened inside the base 201a, and a photovoltaic panel 201e adapted to be installed inside the mounting groove 201d.

[0061] In addition, the sliding component 202 includes a slide cylinder 202a fixedly connected to the bottom end of the base 201a, and a straight groove 202b opened inside the slide cylinder 202a;

[0062] The slide cylinder 202a is slidably connected to the outside of the limiting rod 102b;

[0063] There are three slide cylinders 202a, and the slide cylinder 202a located in the middle of the base 201a is provided with threads inside, so that the slide cylinder 202a in the middle can be threadedly connected with the threaded rod 102d.

[0064] When the photovoltaic panels 201e need to be stacked, the motor 102e is started to drive the threaded rod 102d to rotate, thereby cooperating with the slide cylinder 202a with threads inside to drive the base 201a to move.

[0065] The base 201a drives the photovoltaic panel 201e to move synchronously. When the base 201a closest to the containing box 103a completely enters the containing box 103a, it will be supported by the horizontal plate 103c, and the adjacent base 201a will gradually enter the containing box 103a while continuing to move. At this time, the second inclined surface 201c on the outside of the base 201a that is entering will squeeze the first inclined surface 201b on the outside of the base 201a that has already entered. Under the action of the squeezing force, the base 201a that has already entered will move downward, thereby driving the horizontal plate 103c to move downward and squeezing the first spring 103d.

[0066] This process is repeated until all bases 201a are stacked and placed inside the receiving box 103a.

[0067] It is worth noting that both sides of the ring 102f-1 should have threads formed by the threaded rod 102d, as shown in the attached Figure 4 As shown, if there is no threaded rod 102d on the right side of the ring 102f-1, when the left end of the last base 201a moves to the outside of the ring 102f-1, the threaded rod 102d continues to rotate. At this time, since the slide cylinder 202a of the base 201a is no longer engaged with the threaded rod 102d, the base 201a no longer moves, so that the base 201a cannot be detached from the outside of the ring 102f-1, and it cannot completely enter the containing box 103a.

[0068] When a threaded rod 102d is also provided on the right side of the ring 102f-1, when the left end of the base 201a moves to the outside of the ring 102f-1, the slide 202a is still engaged with the threaded rod 102d on the right side of the ring 102f-1, so that the base 201a can continue to move until it completely enters the containing box 103a and is separated from the threaded rod 102d.

[0069] When the photovoltaic panels 201e are stacked together, the light transmittance is the largest, the power generation efficiency is the lowest, and the agricultural light usage is the largest; when the photovoltaic panels 201e are stretched out, the light transmittance is the smallest, the power generation efficiency is the highest, and the agricultural light usage is the smallest.

[0070] For example, the "lunch break" time of tomatoes is from 12 noon to 2 o'clock, and the light intensity at the light saturation point is 70,000 lux. When the monitored light intensity is greater than 70,000 lux, the position of the photovoltaic panel 201e should be adjusted from 12 noon to 2 o'clock to reduce the amount of light transmitted and generate sufficient electricity.

[0071] In addition, when the wind force level exceeds the design wind speed level of the flexible bracket, multiple groups of photovoltaic panels 201e can be stacked to reduce the windward surface of the photovoltaic panels, thereby achieving a wind shelter effect and ensuring structural safety. In addition, the power for the rotation of the motor 102e can be supplied by the photovoltaic panel 201e to achieve self-power supply.

[0072] In addition, this device can also be applied to the high-value fruit honey plum in Guizhou. Photovoltaic panels can be used to block hail, preventing hail from damaging high-value fruits and increasing the yield of honey plums. It can also prevent high-temperature sunlight from directly shining on the fruits and block sudden rainfall on hot days, effectively reducing the cracking of honey plums.

[0073] In summary, through the mutual cooperation of the auxiliary component 102, the accommodating component 103, the mounting component 201 and the sliding component 202, when the photovoltaic panels 201e need to be stored, the motor 102e can be started to move multiple photovoltaic panels 201e to the inside of the accommodating box 103a and stack them, so that the sunlight can be utilized to a greater extent to achieve the effect of agricultural and photovoltaic complementarity, and in extreme weather, the photovoltaic panels 201e can be protected by the operation of storing the photovoltaic panels 201e.

[0074] Example 3

[0075] Reference Figure 1 to Figure 7 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that another working state of the main mechanism 200 is provided.

[0076] It is worth noting that since a telescopic assembly 103f is provided inside the containing box 103a, when the base 201a enters the containing box 103a, the right side of the base 201a will squeeze the cone block 103f-1, causing the cone block 103f-1 to rise and compress the second spring 103f-2.

[0077] Therefore, the base 201a located at the top inside the containing box 103a is always squeezed by the cone block 103f-1, so that the base 201a always has a tendency to move to the left, that is, the slide tube 202a outside the base 201a is always in close contact with the end of the threaded rod 102d.

[0078] When resetting is required, it is only necessary to reverse the motor 102e so that the motor 102e drives the threaded rod 102d to reverse. Since the slide 202a is always in close contact with the end of the threaded rod 102d, when the threaded rod 102d is reversed to engage with the internal thread of the slide 202a, the slide 202a can be re-engaged with the threaded rod 102d with the cooperation of the cone block 103f-1 and the threaded rod 102d, so that the slide 202a is reset as the threaded rod 102d reverses.

[0079] When one base 201a completely leaves the containing box 103a, the other base 201a will move to the top of the containing box 103a under the rebound force of the first spring 103d, and the above operation is repeated to complete the overall reset.

[0080] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary.
