Description

Technical Field

[0001] The present invention relates to the field of photovoltaic technology, and in particular to a photovoltaic installation structure for an agricultural greenhouse. Background Art

[0002] Solar energy is a new energy source characterized by environmental friendliness, energy conservation, and freedom from time and space constraints. In today's global resource shortage, solar energy has gained widespread favor, leading to the emergence of solar photovoltaic modules. A photovoltaic module consists of several solar cells connected in series and parallel, tightly sealed together. Its function is to convert solar energy into electricity, which is then stored in batteries or used to power loads. As the field of solar photovoltaic technology matures, it is being applied in a growing number of industries, such as livestock farming and agricultural greenhouses.

[0003] In the existing technology, there are two forms of solar photovoltaic agricultural greenhouses. One is to use solar photovoltaic and greenhouse integrated construction at the time of greenhouse construction, thus forming a modern photovoltaic agricultural integrated ecological greenhouse. The other is to add improvements to the built greenhouse. Since the internal construction bracket of the greenhouse has an arc and the support strength is insufficient, in order to apply solar photovoltaic technology to agricultural greenhouses, people build solar photovoltaic panels in the interval space between greenhouses. This not only causes the rear space of the greenhouse to be blocked, affecting the lighting of the crops at the rear of the greenhouse, but also this method can only provide energy to the agricultural greenhouse, and cannot provide protection for the greenhouse like a modern photovoltaic agricultural integrated ecological greenhouse. If you want to use the installation of a modern photovoltaic agricultural integrated ecological greenhouse, it will take a lot of time to remove the existing greenhouse film and then renovate and install a new roof. This often takes at least 1 week, but for greenhouses that are in use 365 days a year, it affects the growth of crops in the greenhouse. Summary of the Invention

[0004] The purpose of the present invention is to provide an agricultural greenhouse photovoltaic installation structure that will not affect the supporting strength of the internal bracket of the greenhouse and can transform the greenhouse into a modern photovoltaic agricultural integrated ecological greenhouse without dismantling the greenhouse roof, which can provide a protective effect for the greenhouse.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: A photovoltaic mounting structure for an agricultural greenhouse, comprising a greenhouse film support rod, and front and rear legs arranged on the front and rear sides of the greenhouse, wherein the top of the greenhouse film support rod is provided with multiple fixing assemblies, and both sides of the fixing assembly are slidably connected to an adjustment chain with adjustable rotation angles between adjacent chain links through a height adjustment screw and a first fixed plate, the adjustment chain includes a locking mechanism for locking adjacent chain links, the adjustment chain is provided with multiple adjustment gears, each of which is driven by a stepper motor and the extension length of each tooth can be individually adjusted, the stepper motor is slidably connected to the adjustment chain through a second fixed plate, and multiple photovoltaic panels slide on the adjustment chain, each photovoltaic panel is plugged into a sliding block through a plug-in component, the sliding block slidably cooperates with the adjustment chain, and the multiple photovoltaic panels are connected through a flexible component, and the photovoltaic panels and the adjustment gears are plugged into each other through an electromagnetic plug-in, the front leg is connected to the bottom end of the adjustment chain, and the rear leg is connected to the adjustment chain at the top position of the second fixed plate corresponding to the second stepper motor at the top of the top of the greenhouse film support rod.

[0006] The present invention also has the following beneficial effects:

[0007] The present invention adjusts the chain, stepper motor, locking mechanism and the like through mutual coordination. During the installation process, the locking mechanism of the adjustment chain is controlled to form a fixed connection between the chain and support the photovoltaic panel, thereby reducing the influence of the photovoltaic panel on the support strength of the greenhouse film support rod and reducing the pressure load of the photovoltaic panel on the greenhouse film support rod. Secondly, the solar photovoltaic panel can be installed on the top of the greenhouse without removing the greenhouse film, thereby increasing economic benefits.

[0008] The present invention adjusts the coordination between the chain, stepper motor, locking mechanism, etc., and controls the upward movement of the photovoltaic panels between any two greenhouse film support rods, thereby achieving the effect of adjusting the light intensity. Conversely, it can also shield the entire greenhouse, thereby making the greenhouse suitable for the growth of some crops with low light intensity requirements.

[0009] The present invention adjusts the cooperation between the chain, the stepper motor, the locking mechanism, etc., and adjusts the locking mechanism at the top of the adjustment chain to select a suitable turning point, so that the top adjustment chain is bent. On the one hand, it prevents the top motor from sliding freely along the chain. On the other hand, it limits the position of the first stepper motor at the top to avoid the situation in which the straw insulation layer cannot be reeled in due to the first stepper motor at the top sliding along the chain when the insulation layer is subsequently reeled in.

[0010] 4. The present invention can achieve the folding of the top photovoltaic panel by adjusting the mutual coordination among the chain, the stepper motor, the locking mechanism, etc. and by controlling the adjusting components of the adjusting chain, so as to block the edge gap between the greenhouse and the photovoltaic panel in heavy snow weather to prevent rain and snow from entering the gap and causing the greenhouse to collapse; after folding, all the stepper motors except the stepper motor corresponding to the first photovoltaic panel are controlled to rotate forward and reverse repeatedly, so that the stepper motor drives the photovoltaic panel to slide up and down repeatedly and clears the rain and snow on the top, thereby clearing the snow on the top of the photovoltaic panel, thereby avoiding the accident of heavy snow causing the roof to collapse.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] Reference Figures 1-8 A photovoltaic installation structure for an agricultural greenhouse includes a greenhouse film support rod 1, and front legs 2 and rear legs 3 arranged on the front and rear sides of the greenhouse. Multiple fixing components 6 are provided on the top of all greenhouse film support rods 1. Both sides of the fixing components 6 are slidably connected to an adjusting chain 9 with adjustable rotation angles between adjacent chain links through a height adjustment screw 7 and a first fixing plate 8. The adjusting chain 9 includes a locking mechanism 18 for locking adjacent chain links. A plurality of adjusting gears are provided in the adjusting chain 9, each of which is driven by a stepping motor 12 and the protruding length of each tooth can be adjusted individually. The stepping motor 1 2 is slidably connected to the adjustment chain 9 through the second fixed plate 13. A plurality of photovoltaic panels 17 slide on the adjustment chain 9. Each photovoltaic panel 17 is plugged into the sliding block 15 through a plug-in component. The sliding block 15 slides with the adjustment chain 9, and the plurality of photovoltaic panels 17 are connected through a flexible component 16. The photovoltaic panel 17 and the adjustment gear are plugged through an electromagnetic plug. The front support leg 2 is connected to the bottom end of the adjustment chain 9, and the rear support leg 3 is connected to the adjustment chain 9 at the top position of the second fixed plate 13 corresponding to the second stepping motor 12 at the top of the greenhouse film support rod 1.

[0023] During heavy snow, the electromagnetic pin corresponding to the first stepper motor 12 at the top of the greenhouse film support rod 1 is controlled to be disconnected, so that the first photovoltaic panel 17 on the top is disconnected from the stepper motor 12, and the connector between the first photovoltaic panel 17 on the top and the sliding block 15 is controlled to be disconnected, and the first photovoltaic panel 17 on the top and the second photovoltaic panel 17 are rotated. Then, a suitable turning point is selected, and the locking mechanism 18 corresponding to the turning point is controlled to be unlocked, so that the top of the adjustment chain 9 is bent, and the electromagnetic pin corresponding to the first stepper motor 12 on the top is controlled to extend and insert into the docking slot on the side of the photovoltaic panel 17. Then, all the stepper motors 12 except the stepper motor 12 corresponding to the first photovoltaic panel 17 are controlled to rotate forward and reverse repeatedly, and at the same time, the corresponding adjusting gear is controlled to engage only with the lower chain of the adjusting chain 9, so that the stepper motor 12 drives the photovoltaic panel 17 to slide up and down repeatedly, and clears the rain and snow on the top, thereby clearing the snow on the top of the photovoltaic panel 17, thereby avoiding the accident of heavy snow collapsing the roof.

[0024] The fixing assembly 6 includes a support seat 601, and a first curved plate 602 is provided at the bottom of the support seat 601. The first curved plate 602 is detachably connected to the second curved plate 603 through bolts and nuts 4. The present invention provides a fixing assembly 6, which can play a positioning and guiding role when installing the adjustment chain 9, thereby facilitating the installation of the adjustment chain 9 and adjusting the tightness of the adjustment chain 9.

[0025] Height adjustment screws 7 are symmetrically provided on the left and right sides of the fixing component 6, and a first fixing plate 8 is fixed on the top of the height adjustment screw 7. The first fixing plate 8 is "U"-shaped, and the first guide blocks 801 are symmetrically provided on the top and bottom of the first fixing plate 8. The first guide block 801 is located in the gap between the two inner links of the adjustment chain 9 and is slidingly connected to the adjustment chain 9. By setting the fixing component 6, the present invention can play a positioning and guiding role when installing the adjustment chain 9, thereby facilitating the installation of the adjustment chain 9 and adjusting the tightness of the adjustment chain 9.

[0026] The adjustment chain 9 includes inner links and outer links, and the inner links and outer links are connected by a pin 901. The inner links and outer links are hinged by the pin 901, so that two adjacent inner and outer links can rotate.

[0027] The locking mechanism 18 includes a through hole 1801, which is provided on the outer chain link and on the side opposite to the first fixed plate 8; a pin 1802 is provided in the through hole 1801, and the pin 1802 is connected to the outer wall of the outer chain link through a spring 1804, and the inner chain link is opposite to the through hole 1801 and is provided with a recessed groove 1803 that cooperates with the pin 1802 in a circular array around the axis of the pin shaft 901. The present invention provides a locking mechanism 18, and when the pin 1802 is pulled out, the pin 1802 corresponding to the adjusting gear is pulled out from the recessed groove 1803, so that the inner chain link and the outer chain link form a movable connection; when the pin 1802 is released, the pin 1802 is reinserted into the recessed groove 1803 under the action of the elastic force of the spring 1804, continuing to form a locked state, so that the adjustment chain 9 is in a locked and non-adjustable state.

[0028] The adjusting gear includes a disc 10, and a plurality of grooves are provided in a circumferential array on the side wall of the disc 10. The grooves are connected to convex teeth 11 that cooperate with the adjusting chain 9 through electric telescopic rods 5. The present invention provides convex teeth 11 with adjustable extension lengths, so that according to the number of rotation steps of the stepping motor 12, the convex teeth 11 are controlled to extend in sequence and then contract in sequence, thereby realizing that the adjusting gear only engages with the lower chain of the adjusting chain 9.

[0029] The axis of the adjusting gear is connected to the output shaft of the stepping motor 12 through a rotating shaft. A second fixed plate 13 is provided at the end of the stepping motor 12 away from the output shaft. The top and bottom of the second fixed plate 13 are provided with a second guide plate 14 that slides with the adjusting chain 9. The present invention can serve as a fixing seat for fixing the stepping motor 12 by setting the second fixed plate 13 and the second guide plate 14. Since the adjusting chain 9 is in a locked state and the second guide plates 14 are mounted on both sides of the adjusting chain 9 and serve as a guiding sliding, when the stepping motor 12 rotates, it will not drive the second guide plate 14 to rotate. Since the second guide plate 14 cannot rotate, the adjusting gear rotates, and the adjusting gear rotates and drives the photovoltaic panel 17 and the second guide plate 14 to slide along the adjusting chain 9, thereby realizing the movement of the photovoltaic panel 17.

[0030] The side wall of the photovoltaic panel 17 is provided with a plurality of sockets that cooperate with the electromagnetic plug. The present invention can facilitate the adjustment of the position of the electromagnetic plug and the photovoltaic panel 17 by providing a plurality of sockets.

[0031] First, fix the front legs 2 and the rear legs 3 on the front and rear sides of the greenhouse, and then fix multiple fixing components 6 to each greenhouse film support rod 1 on the greenhouse through bolts and nuts 4; then adjust the height of each height adjusting screw 7 so that the first fixing plate 8 at the top of the same greenhouse film support rod 1 is in the same straight line, and then dock the adjusting chain 9 with the front legs 2 and the rear legs 3, and dock with each first fixing plate 8 and the second fixing plate 13. After completing the docking of the adjusting chain 9, the adjusting gear is simultaneously placed into the adjusting chain 9 during the docking process of the adjusting chain 9, and through the adaptive adjustment locking mechanism 18, the adjusting chain 9 is turned at both ends to match the outer edge of the disc 10 of the adjusting gear, and then the sliding block 15 is plugged into the photovoltaic panel 17 through the connector, and the stepping motor 12 is plugged into the photovoltaic panel 17 through the electromagnetic latch, so that the installation of the photovoltaic structure of the agricultural greenhouse can be completed.

[0032] Through the above-mentioned installation structure, the present invention can install the solar photovoltaic panel 17 on the top of the greenhouse without removing the greenhouse film. The installed photovoltaic panel 17 can, on the one hand, shield the top of the greenhouse from rain and snow, and secondly, it can adjust the light intensity without affecting the light in the greenhouse. On the contrary, it can shield some crops with low light intensity requirements, thereby increasing economic benefits. Thirdly, it can also reduce the pressure load of the photovoltaic panel 17 on the greenhouse film support rod 1.

[0033] When it is necessary to adjust the light intensity in the greenhouse, the photovoltaic panel 17 between any two of the greenhouse film support rods 1 is controlled to move upward, so that the light intensity of the greenhouse can be adjusted. Specifically, the bottom stepper motor 12 corresponding to the group of photovoltaic panels 17 is controlled to start, and the adjusting gear corresponding to the bottom stepper motor 12 is controlled so that the adjusting gear is only engaged with the lower part of the chain. Since the second fixed plate 13 is slidingly connected to the adjusting chain 9, and the second fixed plate 13 is connected to the stepper motor 12, the stepper motor 12 drives the second fixed plate 13 to slide upward along the adjusting chain 9. At the same time, according to the upward sliding situation of the photovoltaic panel 17, the electromagnetic latch corresponding to each stepper motor 12 is controlled to retract from top to bottom, so that the photovoltaic panel 17 is disconnected from the stepper motor 12, thereby avoiding the situation where the stepper motor 12 moves to the top position of the adjusting chain 9, resulting in the adjusting chain 9 limiting the motor and failing to drive the photovoltaic panel 17 to move upward.

[0034] When it is necessary to roll up the straw insulation layer on the top of the greenhouse, the electromagnetic pin corresponding to the first stepper motor 12 on the top is controlled to be disconnected, so that the first photovoltaic panel 17 on the top is disconnected from the stepper motor 12, and then a suitable turning point is selected and the pin 1802 corresponding to the turning point is pulled out to bend the top of the adjustment chain 9. On the one hand, it prevents the top motor from sliding freely along the chain, and on the other hand, the chain limits the first stepper motor 12 on the top to avoid the situation that the straw insulation layer cannot be rolled up due to sliding of the first stepper motor 12 along the chain when the insulation layer is subsequently rolled up; then the electromagnetic pin corresponding to the first stepper motor 12 on the top is controlled to extend, so that the electromagnetic pin is connected to the winding rod for winding up the straw insulation layer, and at the same time, the convex teeth of the adjusting gear corresponding to the first stepper motor 12 on the top are controlled to retract completely, and then the first stepper motor 12 on the top is controlled to start, thereby driving the winding rod for winding up the straw insulation layer to rotate, thereby rolling up the straw insulation layer.

[0035] When encountering a blizzard, the electromagnetic pin corresponding to the first stepper motor 12 on the top is controlled to be disconnected, so that the first photovoltaic panel 17 on the top is disconnected from the stepper motor 12, and the connector between the first photovoltaic panel 17 on the top and the sliding block 15 is controlled to be disconnected, so that the first photovoltaic panel 17 on the top and the second photovoltaic panel 17 are rotated, and then a suitable turning point is selected, and the pin 1802 on the locking mechanism 18 corresponding to the turning point is controlled to be pulled out from the groove 1803 to achieve unlocking, and then the adjustment chain 9 can be rotated to bend the top of the adjustment chain 9, and the electromagnetic pin corresponding to the first stepper motor 12 on the top is controlled to extend and insert into the docking slot on the side of the photovoltaic panel 17, which limits the first photovoltaic panel 17 on the one hand, so that the top photovoltaic panel can be folded, and the edge gap between the greenhouse and the photovoltaic panel can be blocked in blizzard weather to prevent rain and snow from entering the gap and causing the greenhouse to collapse. On the other hand, a certain margin is left for the second stepper motor 12 to move upward, and then all the stepper motors 12 except the stepper motor 12 corresponding to the first photovoltaic panel 17 are controlled to rotate forward and reverse repeatedly, and at the same time, the corresponding adjustment gears are controlled to engage only with the lower chain of the adjustment chain 9, so that the stepper motor 12 drives the photovoltaic panel 17 to slide up and down repeatedly, and clears the rain and snow on the top, thereby clearing the snow on the top of the photovoltaic panel 17, thereby avoiding the accident of heavy snow collapsing the roof.
