Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic system structure design, and in particular to a remote group control bracket. Background Art

[0002] With the development of society, traditional fuel energy is becoming increasingly scarce and its environmental damage is becoming increasingly prominent. This has greatly promoted the use and development of renewable energy. Humanity hopes that renewable energy can change the energy structure and maintain long-term sustainable development. Among the many renewable energy sources, solar energy has become a focus of attention due to its unique advantages. The abundant solar radiation energy is a vital energy source that is inexhaustible, pollution-free, inexpensive, and freely accessible to humans.

[0003] To improve solar energy conversion efficiency, photovoltaic tracking systems have emerged. These systems aim to improve solar energy conversion by tracking the angle of sunlight. Existing solar photovoltaic systems are typically arranged in multiple rows and columns. To control the overall system, a controller typically drives the rotation of photovoltaic panels in a specific row or column, and then controls the rotation of panels in other rows and columns through structures such as connecting rods. This linkage arrangement results in poor system adaptability, high energy consumption, low system efficiency, and a complex overall structure, resulting in high equipment investment costs.

[0020] 1. The number of transmission ropes in the remote group control bracket of the present invention can be one or two, and their working principles are basically the same. One transmission rope can adjust the angle of the load on the sub-tracking bracket in one degree of freedom by driving the actuator linked to the sub-tracking bracket, while two transmission ropes can adjust the angle of the load on the sub-tracking bracket in two degrees of freedom. The present invention drives multiple sub-tracking brackets by controlling the transmission rope. Since the transmission rope is a flexible structure, the present invention is not only applicable to relatively flat terrain, but also to uneven terrain. It has good adaptability to the terrain. Moreover, the wire rope can directly drive the angle adjustment between each sub-tracking during operation, and the operation is stable and efficient.

[0024] 5. In the present invention, one end of the connecting rod for fixing the pressure wheel is hinged to its fixing frame.

DETAILED DESCRIPTION

[0043] To more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive effort. To simplify the drawings, only the parts related to the present invention are schematically shown in each figure, and they do not represent the actual structure of the product. Specific embodiment 1

[0045] like Figures 1 to 4 This specific embodiment discloses a remote group control bracket, comprising a transmission rope 1, multiple actuators 3, and multiple sub-tracking brackets 4. Specifically, the transmission rope 1 in this embodiment is a steel wire rope, and a sub-drive device 43 is connected to the transmission rope 1. The sub-drive device 43 is used to drive the transmission rope 1 to move. Multiple actuators 3 are connected in series to the transmission rope 1. Each actuator 3 includes an input shaft and an output shaft. The input shaft 31 of each actuator 3 is linked to its output shaft 32. The input shaft 31 of each actuator 3 abuts the transmission rope 1. When the sub-drive device 43 moves the transmission rope 1, the transmission rope 1 drives the input shaft 31 of each actuator 3 to rotate, which in turn drives the linked output shaft 32 to rotate. The sub-tracking brackets 4 correspond one-to-one with each actuator 3, and the input shafts of each sub-tracking bracket 4 are linked to the input shafts of the corresponding actuator 3. The input shafts of each sub-tracking bracket 4 are used to adjust the angle of a load 41 on the sub-tracking bracket 4 within one degree of freedom.

[0046] In this embodiment, the sub-tracking bracket 4 includes a base and multiple columns. The main beam is rotatably set on the multiple bases. The main beam is provided with multiple photovoltaic component panels 41 arranged side by side. The output shaft of the actuator 3 is connected to the main beam through a reduction mechanism. The reduction mechanism here can be a worm gear reducer, a gear screw reducer or a planetary gear reducer, etc. Figure 1 The remote group control bracket shown in is applied to a flat single-axis photovoltaic system.

[0047] like Figure 2 、 3 As shown, in this embodiment, an input wheel 33 is provided at one end of the input shaft in the actuator 3, and the input wheel 33 is coaxially fixedly connected to the input shaft. The actuator 3 also includes a pressure wheel 34, which is parallel to the central axis of the input wheel 33. The pressure wheel 34 is located on one side of the input wheel 33. There is a gap between the pressure wheel 34 and the input shaft for the transmission rope 1 to pass horizontally. The pressure wheel 34 abuts against the transmission rope 1. The pressure wheel 34 is used to apply pressure to the transmission rope 1, so that the transmission rope 1 drives the input wheel 33 to rotate when it moves, and the rotation of the input wheel 33 drives the input shaft linked with it to rotate.

[0048] Specifically, such as Figure 3As shown, the actuator 3 also includes a fixed frame 36, which includes a first vertical plate 361, a second vertical plate 362 and a bottom plate 363. The first vertical plate 361 and the second vertical plate 362 are both vertically arranged on the bottom plate 363, and there is a distance between the first vertical plate 361 and the second vertical plate 362. The input shaft in the actuator 3 passes through the first vertical plate 361 and the second vertical plate 362 in sequence and is linked to the output shaft in the actuator 3. The input wheel 33 on the input shaft in the actuator 3 is located on the side of the first vertical plate 361 away from the second vertical plate 362. The pressure wheel 34 is rotatably arranged at the first end of a connecting rod 35. The second end of the connecting rod 35 passes through the first vertical plate 361 and is arranged on the second vertical plate 362. The connecting rod 35 is parallel to the input shaft of the actuator 3.

[0049] Specifically, the through-hole in the first riser 361 through which the connecting rod 35 passes is a strip-shaped slot, extending perpendicularly to the direction in which the transmission rope 1 passes through the gap between the input pulley 33 and the pressure pulley 34. The connecting rod 35 can slide along the strip-shaped slot, and the second end of the connecting rod 35 is hinged to the first riser 361. The connecting rod 35 is also connected to a spring 365, which is fixed to a fixed rod 364 disposed on the first riser 361. Both the fixed rod 364 and the spring 365 are located on the side of the first riser 361 adjacent to the second riser 362. The spring 365 extends and contracts perpendicularly to the axial direction of the connecting rod 35. When the connecting rod 35 is at the bottom of the strip-shaped slot, the spring 365 is in a neutral position. When the connecting rod 35 is offset from the bottom of the strip-shaped slot, the spring 365 is in a stretched position.

[0050] The remote group control bracket in this specific embodiment drives the movement of the wire rope through a sub-drive device 43, which further drives the adjustment of the angle change of the load (i.e., photovoltaic component panels 41) on multiple sub-tracking brackets 4. The sub-tracking brackets 4 do not need to be equipped with a separate electronic control system, which simplifies the system structure and reduces the production cost. It can be applied to areas with relatively flat ground. In addition, the operation of the transmission rope 1 and the actuator 3 is stable and reliable, further ensuring the smooth and reliable operation of the overall system.

[0051] Of course, in other specific embodiments of the remote group control bracket of the present invention, the transmission rope can also be other structures such as a belt or chain. When the structure of the transmission rope changes, the linkage structure and method of the transmission rope and the input shaft also change accordingly. For example, when the transmission rope is a chain, the input end of the input shaft is not provided with an input wheel but a sprocket, and the input shaft is transmitted by the engagement between the chain and the sprocket; the transmission rope can be set as a structure with two ends as needed, or it can be set as a closed structure; in addition, the specific linkage structure of the input shaft and the output shaft can be selected and set according to actual needs; the actuator can adjust the structure according to actual needs; the remote group control bracket can also be used to install photothermal components or other forms of loads, which will not be repeated here. Specific embodiment 2

[0053] like Figure 5 As shown, this specific embodiment discloses another remote group control bracket, whose structure is substantially the same as that of the first specific embodiment, differing only in the specific structure of the sub-tracking bracket. In this embodiment, the sub-tracking bracket includes multiple bases and main beams. The main beams are rotatably mounted on the bases. Multiple photovoltaic panels 41 are fixed to the main beams. Each photovoltaic panel corresponds to a slewing mechanism driven by a sub-wire rope. The sub-transmission rope 42 is connected to a sub-drive device 43, which is used to drive the sub-transmission rope 42 to move. The sub-drive device 43 drives the sub-transmission rope 42 to move, which in turn drives the slewing mechanism, which in turn drives the corresponding main beam to rotate.

[0054] Specifically, the remote group control bracket in this embodiment is specifically applied to an oblique single-axis photovoltaic system. Of course, in other embodiments, the load may also be a photothermal component or other forms of load. Specific embodiment three

[0056] like Figure 6 As shown, this specific embodiment discloses another remote group control bracket, whose structure is basically the same as that of the specific embodiment 1, except that the arrangement of the pressure wheel 34 in the actuator 3 is different. In this embodiment, the actuator 3 also includes a pressure wheel 34, which is arranged on one side of the input wheel 33 and abuts the transmission rope 1. The transmission rope 1 is wound around the pressure wheel 34 and the input shaft, and forms an S-shaped structure when passing through the pressure wheel 34 and the input shaft. The pressure wheel 34 applies pressure to the transmission rope 1, causing the transmission rope 1 to rotate the input wheel 33 as it moves. The rotation of the input wheel 33 drives the input shaft to rotate in conjunction with it.

[0057] The actuator 3 in this specific embodiment can effectively stretch the transmission rope 1 on the input wheel 33, thereby further ensuring that the transmission rope 1 can drive the input wheel 33 to rotate through the friction between the input wheel 33 and the input wheel 33 when passing through the input wheel 33, and further drive the input shaft and output shaft of the actuator 3 to rotate. Specific embodiment 4

[0059] like Figure 7As shown, this specific embodiment discloses another remote group control bracket, whose structure is basically the same as that of the specific embodiment 1, except that the arrangement of the pressure roller 34 in the actuator 3 is different. In this embodiment, the actuator 3 includes a pair of pressure rollers 34, which are arranged on both sides of the input wheel 33. The pair of pressure rollers 34 press the transmission rope 1 from both sides of the input shaft. Along the movement direction of the transmission rope 1, the transmission rope 1 in the actuator 3 is first wound around one of the pressure rollers 34, then around the input wheel 33, and finally around the other pressure roller 34. When the transmission rope 1 moves, the friction force drives the input wheel 33 to rotate, and the rotation of the input wheel 33 drives the input shaft to rotate. Specific embodiment five

[0061] like Figure 8 As shown, the present invention also discloses another remote group control bracket, comprising a pair of transmission ropes 1, a pair of drive devices 2, multiple pairs of actuators 3, and multiple sub-tracking brackets 4. The transmission ropes 1 are steel wire ropes, and the drive devices 2 correspond one-to-one with each transmission rope 1, driving the corresponding transmission rope 1 to move. Specifically, the sub-tracking brackets 4 in this embodiment include a base, a main beam, and a reduction mechanism. The main beam is rotatably mounted on the bracket and is used to mount a load. The main beam is connected to the output shafts of the actuators via the reduction mechanism. Multiple actuators 3 are connected in series to the transmission ropes 1. The number of actuators 3 on a pair of transmission ropes 1 is the same, and the actuators 3 on one transmission rope 1 correspond one-to-one with the actuators 3 on the other transmission rope 1 (i.e., they are arranged in pairs). The actuators 3 include input shafts and output shafts. The input shafts of the actuators 3 are linked to their output shafts and abut against the transmission rope 1. When the transmission rope 1 moves, the transmission rope 1 drives the input shafts of the actuators 3 to rotate, and the rotation of the input shafts of the actuators 3 drives the output shafts linked to them to rotate. Each sub-tracking bracket 4 includes a dual-degree-of-freedom rotation mechanism 44, which includes two independent input shafts. The two input shafts in the dual-degree-of-freedom rotation mechanism 44 are respectively used to adjust the angle of the load (i.e., photovoltaic component panel 41) on the sub-tracking bracket 4 in two degrees of freedom. One input shaft in the dual-degree-of-freedom rotation mechanism 44 is connected to the output shaft of the actuator 3 on one transmission rope 1, and the other input shaft in the dual-degree-of-freedom rotation mechanism 44 is connected to the output shaft of the actuator 3 on another transmission rope 1. One dual-degree-of-freedom rotation mechanism 44 corresponds to a pair of actuators 3.

[0062] Specifically, the dual-degree-of-freedom rotary mechanism 44 includes a first rotary mechanism 441 and a second rotary mechanism 442. The first rotary mechanism 441 and the second rotary mechanism 442 both include linked input shafts and output shafts. The input shaft 4411 of the first rotary mechanism 441 is connected to the output shaft of an actuator on one transmission rope, and the input shaft 4421 of the second rotary mechanism is connected to the output shaft of an actuator on another transmission rope. The output shaft 4422 of the second rotary mechanism 442 is rotatably disposed on a fixed plate 4423, and the fixed plate 4423 is fixedly connected to the output shaft 4412 of the first rotary mechanism 441. The output shaft 4422 of the second rotary mechanism 442 is connected to the main beam of its corresponding sub-tracking bracket (a structure for mounting photovoltaic module panels). The output shaft 4412 of the first rotary mechanism 441 is used to adjust the angle of the load (i.e., photovoltaic module panel 41) on the sub-tracking bracket 4 in the first degree of freedom, and the output shaft of the second rotary mechanism is used to adjust the angle of the load (i.e., photovoltaic module panel 41) on the sub-tracking bracket 4 in the second degree of freedom.

[0063] Specifically, such as Figure 9 As shown in (b), the upper transmission rope in the figure drives the input shaft 4411 of the first rotating mechanism 441 to rotate through the upper actuator, the output shaft 4412 of the first rotating mechanism 441 rotates and drives the fixed plate 4423 to rotate, and the fixed plate 4423 further drives the second rotating mechanism 442 connected to the photovoltaic module disposed on the fixed plate 4423 to rotate, thereby adjusting the angle of the load (i.e., the photovoltaic module panel 41) on the sub-tracking bracket 4 connected to the second rotating mechanism 442 in the first degree of freedom. When the lower transmission rope drives the input shaft 4421 of the second rotating mechanism 442 to rotate through the lower actuator, the output shaft 4422 of the second rotating mechanism 442 rotates and adjusts the angle of the photovoltaic module panel 41 connected thereto in the second degree of freedom.

[0064] In this specific embodiment, the actuator can adopt any one of the actuators disclosed in Examples 1, 3, and 4. Of course, in other specific embodiments, the actuator can also be adjusted in specific structure according to actual needs; the transmission rope can also be selected as a belt or chain or other structure as needed; the structure of the sub-tracking bracket can also adopt the structure disclosed in Examples 1 and 2. Of course, the sub-tracking bracket can also be adjusted in specific structure according to actual needs.

[0065] Example 6

[0066] like Figure 10 、 11As shown, the present invention also discloses another remote group control bracket, whose structure is basically the same as the structure in the specific embodiment 1, with the only difference being that, in this embodiment, a groove 331 is provided on the periphery of the input wheel 33, and the transmission rope 1 is wrapped around the groove 331 of the input wheel 33. In addition, there is a preset angle between the travel direction of the transmission rope 1 and the rotating surface of the input wheel 33, and the preset angle here is greater than zero degrees. There is a spacing between the transmission ropes located in the groove 331 of the input wheel 33. This arrangement can not only increase the friction between the transmission rope and the input wheel, but also prevent the transmission rope from contacting in the groove and causing wear.

[0067] Of course, the improvements to the input wheel and the connection method between the transmission rope and the input wheel in this embodiment can be applied to embodiments 2 to 5, and will not be described in detail here.

[0068] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
