Description

Technical Field

[0001] The utility model relates to the technical field of supporting structures, in particular to a turning drive device, a turning system and a photovoltaic panel turning system. Background Art

[0002] Solar energy is a clean energy source that uses photovoltaic panels to absorb solar radiation and convert it into electricity. During installation, photovoltaic panels require a bracket to secure them. To maximize solar energy collection, the bracket adjusts the angle of the panels, ensuring they are at the optimal angle for collecting solar energy at all times.

[0003] In the prior art, while the bracket fixes the flip part, multiple adjustment devices are used to adjust the angle of the flip part. However, the multiple adjustment devices need to be linked to adjust the flip part. The structure of the multiple adjustment devices is complex and the coordination is poor, resulting in a high failure rate. Utility Model Content

[0040] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In addition, when describing pipelines or channels, the "connected" and "connected" used in this application have the meaning of conduction. The specific meaning needs to be understood in conjunction with the context.

[0042] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0043] As used herein, "about," "substantially," or "approximately" includes the stated value and an average value that is within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).

[0044] like Figure 1 As shown, the present application provides a flip driving device 10 , which includes a seat body 1 , a first piston 2 , a second piston 3 , a third piston 4 , a first pressing member 31 and a second pressing member 41 .

[0045] The base body 1 is provided with a piston cavity 11, in which the first piston 2, the second piston 3, and the third piston 4 are all slidably disposed. The second piston 3 and the third piston 4 are located on opposite sides of the first piston 2 and spaced apart from the first piston 2. A first pressing member 31 is connected to the second piston 3, and a second pressing member 41 is connected to the third piston 4. The first pressing member 31 and the second pressing member 41 are used to support the part to be flipped 20. The first piston 2 slides along the extension direction of the piston cavity 11 to drive the second piston 3 and the third piston 4 to respectively drive the first pressing member 31 and the second pressing member 41 to move in opposite directions, thereby pushing the part to be flipped 20 to flip.

[0046] Combine Figure 1 and Figure 2 As shown, Figure 2The figure shows the state when the first piston 2 moves close to the second piston 3. When the first piston 2 moves in the piston chamber 11 toward the second piston 3, the second piston 3 is driven by the first piston 2 to slide along the extension direction of the piston chamber 11 and move relatively away from the initial position of the first piston 2. The second piston 3 drives the first pressing member 31 to move the position where the member to be flipped 20 connects to the first pressing member 31 away from the base 1. At the same time, the third piston 4 is driven by the first piston 2 to slide along the extension direction of the piston chamber 11 and move relatively close to the initial position of the first piston 2. The third piston 4 drives the second pressing member 41 to move the position where the member to be flipped 20 connects to the second pressing member 41 closer to the base 1, thus completing the flipping of the member to be flipped 20.

[0047] Through the above-mentioned arrangement, the flipping of the part to be flipped 20 only requires operating the first piston 2, and the adjustment is achieved through a set of devices, without the need for coordination of multiple sets of equipment. The structure is simple, the coordination is improved, and the situation of overall failure of the device caused by failure of a single adjustment device is reduced, thereby reducing the overall failure rate.

[0048] It should be noted that the movement of the first pressing member 31 and the second pressing member 41 in opposite directions refers to the movement of the first pressing member 31 and the second pressing member 41 in a direction close to or away from the initial position of the first piston 2 .

[0049] The embodiments of the present application are described in detail below with reference to the accompanying drawings. Before describing the embodiments of the present application in detail, the application scenarios of the embodiments of the present application are first introduced.

[0050] The present application provides a flipping system 100 , which includes: a to-be-flipped member 20 and a flipping driving device 10 , wherein the to-be-flipped member 20 is connected to a first pressing member 31 and a second pressing member 41 of the driving device.

[0051] In one possible embodiment, the part to be flipped 20 can be a panel with display function, materials and parts that need to be processed, furniture parts, experimental equipment, etc., which need to be flipped or rotated during any process such as production, processing, assembly, transportation or use.

[0052] The present application provides a photovoltaic panel flipping system, including a photovoltaic panel and a flipping drive device 10 , wherein the photovoltaic panel is connected to a first pressing member 31 and a second pressing member 41 of the drive device.

[0053] During use, photovoltaic panels need to maintain a fixed angle with sunlight. However, the angle of the light generated by the sun continues to change from rising to setting. Therefore, a photovoltaic panel flipping system is needed to rotate the photovoltaic panels that collect solar energy so that the photovoltaic panels are at the optimal collection angle from rising to setting, thereby improving the efficiency of solar energy collection and thus increasing power generation.

[0054] In one possible environment, for example, when the wind is strong, the photovoltaic panels need to collect solar energy, causing the extension direction of the photovoltaic panels to intersect with the wind direction. At this time, the photovoltaic panels are subjected to a strong wind force.

[0055] In this case, the photovoltaic panel, under the influence of wind, acts in the opposite direction on the first and second pressing members 31 and 41, which in turn act on the second and third pistons 3 and 4. Because the first, second, and third pistons 2, 3, and 4 are in a linked state, the photovoltaic panel is minimally affected by the wind under the influence of wind, that is, the extension direction of the photovoltaic panel is aligned with the direction of the wind. This reduces the wind load on the photovoltaic panel flip system, thereby reducing erosion on the photovoltaic panel flip system and improving the reliability of the photovoltaic panel flip system.

[0056] In a possible embodiment, the first pressing member 31 and the second pressing member may be a connecting rod, a connecting rod connected to a support rod, or other supporting components, which may be specifically configured according to actual use.

[0057] Continue to see Figure 1 and Figure 2 In one possible embodiment, the piston chamber 11 includes a first chamber 111, a second chamber 112, and a third chamber 113. The second chamber 112 and the third chamber 113 are located on the same side of the first chamber 111, and both the second chamber 112 and the third chamber 113 are connected to the first chamber 111. The first piston 2 is slidably disposed in the first chamber 111, the second piston 3 is slidably disposed in the second chamber 112, and the third piston 4 is slidably disposed in the third chamber 113.

[0058] When the first piston 2 moves toward the second chamber 112, the second piston 3 slides in the second chamber 112 in a direction away from the first chamber 111, and at this time, the third piston 4 slides in the third chamber 113 in a direction toward the first chamber 111. Conversely, when the first piston 2 moves toward the third chamber 113, the second piston 3 slides in the second chamber 112 in a direction toward the first chamber 111, and at this time, the third piston 4 slides in the third chamber 113 in a direction away from the first chamber 111.

[0059] This drives one of the first pressing member 31 and the second pressing member 41 closer to the first cavity 111 and the other away from the base 1, thereby driving the flip member to flip. The flip driving device 10 has a simple structure, improved coordination, and reduced failure rate.

[0060] In a possible implementation, the flip drive device 10 is installed on a wall, and the extension direction of the first chamber 111 is perpendicular to the ground.

[0061] In a possible embodiment, the flip driving device 10 is placed on the ground, and the extension direction of the first chamber 111 is parallel to the ground. This application will be further explained using this embodiment as an example.

[0062] In this way, the flip driving device 10 can be adapted to various installation positions, thereby improving the flexibility of the installation position of the flip driving device 10.

[0063] In a possible implementation, an extension direction of the second chamber 112 is parallel to an extension direction of the third chamber 113 .

[0064] In a possible implementation, an extension direction of the second chamber 112 intersects with an extension direction of the third chamber 113 .

[0065] In a possible implementation, the extension direction of the second chamber 112 and the extension direction of the third chamber 113 are both perpendicular to the extension direction of the first chamber 111 .

[0066] In a possible implementation, the extension direction of the second chamber 112 and the extension direction of the third chamber 113 both intersect with the extension direction of the first chamber 111 .

[0067] Through the above arrangement, the second chamber 112 and the third chamber 113 can be set to different extension directions according to actual usage and purpose, thereby improving the flexibility of the flip drive device 10.

[0068] In a possible implementation, an opening 114 is provided at one end of the second chamber 112 and the third chamber 113 facing away from the first chamber 111 .

[0069] When the second piston 3 and the third piston 4 move in the second chamber 112 and the third chamber 113, respectively, they drive the first pressing member 31 and the second pressing member 41 to move through the opening 114. The opening 114 provides a clearance space for the first pressing member 31 and the second pressing member 41 to move, facilitating the first constant pressure member and the second pressing member 41 to move through the opening 114.

[0070] In a possible implementation, the piston chamber 11 between the first piston 2 and the second piston 3 is filled with liquid, and the piston chamber 11 between the first piston 2 and the third piston 4 is filled with liquid.

[0071] The liquid in the piston chamber 11 can effectively transmit force, and the liquid has a certain compressibility, but the compressibility is small. While playing the role of shock absorption and buffering between the pistons, it can ensure that the pistons are evenly stressed, thereby improving the stability of the system.

[0072] In a possible implementation, the piston chamber 11 between the first piston 2 and the second piston 3 is filled with gas, and the piston chamber 11 between the first piston 2 and the third piston 4 is filled with gas.

[0073] Filling the device with gas can reduce the weight of the device. At the same time, the physical properties of gas are better in low-temperature environments. The flipping of photovoltaic panels used in the aerospace field can reduce the overall launch weight.

[0074] In one possible embodiment, the first piston 2 includes a first plug body 21 and a second plug body 22. The first plug body 21 is located on the side of the second plug body 22 away from the third piston 4, and the second plug body 22 is located on the side of the first plug body 21 away from the second piston 3. The first plug body 21 and the second plug body 22 are both slidingly connected to the inner wall surface of the piston chamber 11, and the first plug body 21 is connected to the second plug body 22.

[0075] The first piston 2 includes a first plug body 21 and a second plug body 22, which increases the sealing between the first plug body 21 and the second plug body 22 and the piston cavity 11 respectively, reduces the leakage of material filled in the piston cavity 11 between the first piston 2 and the second piston 3 through the first piston 2 to the piston cavity 11 between the first piston 2 and the third piston 4. Similarly, reduces the leakage of material in the piston cavity 11 between the first piston 2 and the third piston 4 to the piston cavity 11 between the first piston 2 and the third piston 4.

[0076] In this way, two sets of seals, the first plug body 21 and the second plug body 22, are provided, which can improve the stability of the system and reduce the risk of system failure.

[0077] In a possible embodiment, the first piston 2 includes a connecting member 23 , which is located between the first plug body 21 and the second plug body 22 , with one end of the connecting member 23 connected to the first plug body 21 and the other end connected to the second plug body 22 .

[0078] The connector 23 is located between the first plug 21 and the second plug 22. When the first plug 21 moves, the connector 23 transmits the motion and force of the first plug 21 to the second plug 22. When the second plug 22 moves, the connector 23 transmits the motion and force of the second plug 22 to the first plug 21. This achieves synchronous movement of the first and second plugs 21 and 22.

[0079] At the same time, the connecting member 23 provides support between the first plug body 21 and the second plug body 22 to keep the relative position between the first plug body 21 and the second plug body 22 stable.

[0080] In one possible embodiment, the flip driving device 10 includes a driving member that is in driving connection with the first piston 2 to drive the first piston 2 to slide along the extending direction of the piston chamber 11. The driving member provides power for the first piston 2 to move.

[0081] In a possible implementation, the driving member may be any combination of a motor, a cylinder, a hydraulic cylinder, and gears, racks, chains, and belts connected thereto.

[0082] Combine Figure 1 and Figure 3 As shown, in a possible embodiment, a plurality of second pistons 3 are provided, and the plurality of second pistons 3 are respectively slidably connected to the piston chamber 11, a plurality of first pressing members 31 are provided, and one first pressing member 31 is connected to one second piston 3, and the first piston 2 slides along the extension direction of the piston chamber 11 to drive the plurality of second pistons 3 to drive the plurality of first pressing members 31 to move.

[0083] Multiple second pistons 3 and multiple first pressing members 31 are provided, and the thrust generated by the first piston 2 is evenly distributed on the multiple second pistons 3, so that the flipping member 20 to be flipped is evenly subjected to the force of the first pressing member 31, so that the flipping member flips smoothly during the flipping process, thereby improving the flipping stability of the flipping member.

[0084] At the same time, the parallel operation of multiple second pistons 3 can shorten the response time of the system, thereby achieving rapid flipping.

[0085] In the case of strong winds, the multiple first pressing members 31 have a higher supporting effect on the flipping member 20 to be flipped, reducing the risk of the flipping member 20 to be flipped over, thereby improving the stability of the flipping drive device 10 and the flipping system 100.

[0086] In one possible embodiment, the arrangement direction of the plurality of second pistons 3 is perpendicular to the arrangement direction of the first pressing member 31 and the first pressing member 31. This allows the object 20 to be flipped to be supported in both the arrangement direction of the plurality of second pistons 3 and the arrangement direction of the first pressing member 31 and the first pressing member 31, thereby improving stability.

[0087] For example, the number of the second piston 3 and the first pressing member 31 can be one group, two groups or more groups.

[0088] In one possible embodiment, a plurality of third pistons 4 are provided, and the plurality of third pistons 4 are respectively slidably connected to the piston chamber 11; a plurality of second pressing members 41 are provided, and one second pressing member 41 is connected to one third piston 4; the first piston 2 slides along the extension direction of the piston chamber 11 to drive the plurality of third pistons 4 to drive the plurality of second pressing members 41 to move.

[0089] Multiple third pistons 4 and multiple second pressing members 41 are provided, and the thrust generated by the first piston 2 is evenly distributed on the multiple third pistons 4, so that the flipping member 20 is evenly subjected to the force of the second pressing member 41, so that the flipping member flips smoothly during the flipping process, thereby improving the flipping stability of the flipping member.

[0090] At the same time, the parallel operation of multiple third pistons 4 can shorten the response time of the system, thereby achieving rapid flipping.

[0091] In the case of strong winds, the multiple second pressing members 41 have a higher supporting effect on the flipping member 20 to be flipped, reducing the risk of the flipping member 20 to be flipped over, thereby improving the stability of the flipping drive device 10 and the flipping system 100.

[0092] In one possible embodiment, the arrangement direction of the plurality of third pistons 4 is perpendicular to the arrangement direction of the first pressing member 31 and the second pressing member 41. This allows the object 20 to be flipped to be supported in both the arrangement direction of the plurality of third pistons 4 and the arrangement direction of the first pressing member 31 and the second pressing member 41, thereby improving stability.

[0093] For example, the number of the third piston 4 and the second pressing member 41 can be one group, two groups or more groups.

[0094] Continue to see Figure 1 and Figure 2 In a possible embodiment, the flip drive device 10 includes a support structure, which is connected to the first pressing member 31 and the second pressing member 41. The support structure includes a first support portion 51 and a second support portion 52. The first support portion 51 is hinged to the first pressing member 31, and the second support portion 52 is hinged to the first support portion 51. The second support portion 52 is slidably connected to the second pressing member 41, and the sliding direction of the second support portion 52 intersects with the sliding direction of the second pressing member 41.

[0095] The supporting structure is used to fix the to-be-turned part 20 , and the fixing methods include but are not limited to bolt connection, snap connection, plug-in connection, lock connection, magnetic connection, welding, one-piece molding or adhesive connection.

[0096] The first support portion 51 is hinged to the first pressing member 31 so that the first support portion 51 can rotate relative to the first pressing member 31. The second support portion 52 is hinged to the first support portion 51 so that the first support portion 51 can rotate relative to the second support portion 52.

[0097] When the first piston 2 moves toward the second cavity, the first pressing member 31 lifts one end of the first support portion 51, causing the first support portion 51 to rotate about the hinge position. The second pressing member 41 lowers one end of the second support portion 52. During the lowering process of the second pressing member 41, the second support portion 52 also slides away from the first pressing member 31, providing space for the other end of the first support portion 51 to lower. During this process, the other end of the first support portion 51 and the other end of the second support portion 52 are hinged and rotated.

[0098] In this way, through the above structure, the support structure is rotated, thereby driving the to-be-turned member 20 to turn over. The structure is simple, the coordination is improved, and the overall failure rate can be reduced.

[0099] Combine Figure 1 、 Figure 2 and Figure 4 As shown in a possible embodiment, a sliding hole 521 is provided on the second support portion 52, the second pressing member 41 is passed through the sliding hole 521, the sliding hole 521 extends along the arrangement direction of the first pressing member 31 and the second pressing member 41, and the second pressing member 41 slides along the extension direction of the sliding hole 521.

[0100] During the lowering process of the second support portion 52, the second pressing member 41 is inserted into the sliding hole 521. The sliding hole 521 allows the second pressing member 41 to limit the second support portion 52, restricting the second support portion 52 to slide only along the extending direction of the sliding hole 521. The sliding hole 521 provides a sliding direction for the second support member while restricting the second support portion 52 from sliding in other directions.

[0101] The sliding hole 521 simplifies the installation and adjustment of the second pressing member 41 , and facilitates installation and maintenance.

[0102] In a possible embodiment, the flipping drive device 10 includes a first limiting member 6, which is sleeved on the second pressing member 41 and connected to the second pressing member 41. The first limiting member 6 is located below the second support portion 52, and the size of the first limiting member 6 is larger than the size of the sliding hole 521.

[0103] The first position-limiting member 6 has the function of receiving the second support portion 52 . Meanwhile, the first position-limiting member 6 limits the second support portion 52 from moving toward the first position-limiting member 6 .

[0104] When the second pressing member 41 slides in the sliding hole 521 , the first limiting member 6 can coordinate the movement of the second supporting portion 52 to ensure that the second supporting portion 52 moves along the extending direction of the sliding hole 521 , thereby achieving more precise control and operation.

[0105] In one possible embodiment, the first limiter is cylindrical, and the diameter of the first limiter 6 is larger than the diameter of the sliding hole 521. The first limiter 6 needs to be larger than the size of the sliding hole 521 in a certain direction so that the first limiter 6 is located below the sliding hole 521.

[0106] In a possible embodiment, the flipping drive device 10 includes a second limiting member 7, which is sleeved on the second pressing member 41 and connected to the second pressing member 41. The second pressing member 41 is located on the side of the second support portion 52 away from the first limiting member 6, and the size of the second limiting member 7 is larger than the size of the sliding hole 521.

[0107] The second position-limiting member 7 has a position-limiting effect on the second support portion 52 , restricting the second support portion 52 from moving toward the second position-limiting member 7 .

[0108] When the second pressing member 41 slides in the sliding hole 521 , the second limiting member 7 can coordinate the movement of the second supporting portion 52 to ensure that the second supporting portion 52 moves along the extension direction of the sliding hole 521 , thereby achieving more precise control and operation.

[0109] In one possible embodiment, the second limiter is cylindrical, and the diameter of the second limiter 7 is larger than the diameter of the sliding hole 521. The second limiter 7 needs to be larger than the size of the sliding hole 521 in a certain direction so that the second limiter 7 is located above the sliding hole 521.

[0110] When both the first and second stoppers 6 and 7 are provided, they clamp the first support member, allowing the second support portion 52 to be stably positioned between the first and second stoppers 6 and 7 and to move in a direction perpendicular to the clamping direction of the first and second stoppers 6 and 7. This improves the stability of the second support portion 52.
