Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel installation equipment, and in particular to a steel structure photovoltaic bracket. Background Art

[0002] The equipment and power generation conditions involved in photovoltaic power generation are not harsh and are widely used in people's daily lives. Conventional photovoltaic power generation mainly uses photovoltaic panels installed on the roof. Photovoltaic panels absorb light energy and convert it into direct current that can be directly used to meet people's daily electricity needs. For some large-scale photovoltaic power generation, it is also necessary to use an inverter to increase the current through a step-up transformer to the corresponding grid-connected voltage, and then transmit it to the power grid, and then distribute it to the home for use;

[0003] Photovoltaic panels for power generation are generally fixed with the help of mounting frames and placed together with the mounting frames in a well-lit area. Light intensity, mounting angle and orientation of photovoltaic panels are also key factors affecting photovoltaic power generation. The greater the light intensity, the more photons the photovoltaic panels receive, and the more electricity they generate. A reasonable mounting angle can ensure that the photovoltaic panels receive the most direct sunlight, which can also improve the power generation efficiency of the photovoltaic panels.

[0004] Most of the current photovoltaic brackets adopt a fixed structure, and the installation angle and position of the photovoltaic panels also adopt a fixed structure. Due to the different angles of sunlight exposure during a day, the photovoltaic brackets with fixed structures can only achieve the best power generation performance of the photovoltaic panels during a certain period of time during the day. Therefore, due to the limitations of the location of the photovoltaic panels, the photovoltaic panels cannot fully exert their optimal power generation performance. At the same time, when photovoltaic panels are placed outdoors, in addition to the influence of the light position, they will also be affected by dust in the air, resulting in partial blocking of the photovoltaic panel's illuminated area, which will also affect its power generation effect.

[0043] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0045] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] like Figures 1 to 11As shown, the present invention provides a steel structure photovoltaic bracket, including two groups of columns 1, a mounting frame 2 arranged between the two groups of columns 1 and rotatably connected to the columns 1, and an adjustment component 5 installed in the two groups of columns 1, one of which is used to rotationally drive the mounting frame 2 and the transmission component 3, and transmission components 3 with the same structure and corresponding positions are arranged on both sides of the mounting frame 2, and brush plates 4 with corresponding positions and elastically swinging between the transmission components 3 are arranged on the two groups of transmission components 3.

[0047] Among them, the adjusting component 5 includes an adjusting box 6 and a first reduction box 8 respectively arranged on the top side of the column 1 and the bottom side. A reversing adjusting member is arranged inside the adjusting box 6. The connecting end of the reversing adjusting member passes through the column 1 and is connected with the central part of the side end of the mounting frame 2 through an axle body. The driving end of the reversing adjusting member will be connected to the reduction gear located at the transmission end in the second reduction box 7 arranged outside the adjusting box 6. The driving end of the adjusting box 6 corresponds to the central part of the side end of the mounting frame 2, and a transmission connecting member for driving the transmission component 3 and the reversing adjusting member is arranged between the driving end of the adjusting box 6 and the transmission end of the first reduction box 8.

[0048] Specifically, the reversing adjustment member in the adjustment box 6 mainly realizes the fixed-angle reciprocating rotation of the mounting frame 2 as a whole, so that the photovoltaic panel can be adaptively adjusted according to the position of the sun to achieve the best power generation effect. For example, the round trip time of the mounting frame 2 is 24 hours, and the single time is 12 hours, that is, the starting end of the mounting frame 2 is set to 6 o'clock in the morning, and then 18 o'clock in the afternoon is used as the end of the single rotation. At this point, the starting end of the return end will be 18 o'clock in the afternoon, and then to 6 o'clock in the morning, thus forming a reciprocating motion determined by time.

[0049] Furthermore, in order to achieve synchronization between time and reciprocating motion, the rotation speed of the reversing adjusting member is limited by the second reduction gear box 7. The second reduction gear box 7 uses gears with different gear ratios to change the transmission ratio of the reversing adjusting member. The first reduction gear box 8 and the second reduction gear box 7 have the same principle, and the difference is that the degree of deceleration between the two is different.

[0050] In order to realize the simultaneous movement of the mounting frame 2 and the transmission assembly 3 arranged on the mounting frame 2, as shown in FIG. Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, it is realized by a transmission connecting member, which includes two sets of coaxial gears i1202 and g1103 connected to the reduction teeth at the driving end of the second reduction box 7, a gear f1101 corresponding to the position of the transmission assembly 3 and connected to the transmission assembly 3 through an axle, and a gear h1201 connected to the reduction teeth at the driving end of the first reduction box 8, a chain b11 for synchronous transmission is arranged between the gear g1103 and the gear f1101, and a chain c12 for synchronous transmission is arranged between the gear i1202 and the gear h1201.

[0051] It is further explained that the transmission connection mainly achieves two effects. First, it realizes the transmission effect of the first reduction box 8 on the second reduction box 7. Second, the two reduction boxes transmit the transmission assembly 3 on the mounting frame 2 on the basis of realizing the transmission connection.

[0052] To achieve the above two effects, the set position of the transmission connection must be limited first. Since the transmission assembly 3 is set on the mounting frame 2, when the mounting frame 2 rotates through the reversing adjustment member, the transmission assembly 3 also rotates therewith. Since the rotation of the mounting frame 2 and the transmission assembly 3 is a circular rotation trend, it is only necessary to ensure that the positions of the coaxial gears i1202 and g1103 of the transmission connection correspond to the positions of the rotation points of the mounting frame 2, so that the gears i1202 and g1103 can realize both the transmission of the first reduction box 8 and the transmission assembly 3.

[0053] It should be noted that when the transmission point (gear g1103) is determined, during the rotation of the mounting frame 2, the distance between the gear a301 at the end of the transmission component 3 and the gear g1103 is the same, that is, the radius is the same. Therefore, it is only necessary to connect the gear g1103 and the gear a301 at the end of the transmission component 3 through the gear f1101, the chain b11 and the shaft b1102 respectively to achieve the effect of independent transmission of the transmission component 3 during the rotation of the mounting frame 2.

[0054] At the same time, in order to increase the frequency of the transmission component 3 driving the brush plate 4 to clean the photovoltaic panel, two sets of reduction gearboxes are used to respectively realize the distribution of different speeds of the mounting frame 2 and the transmission component 3, such as Figure 1 , Figure 2 and Figure 6 shown.

[0055] In order to simplify the drive control of the entire regulating component 5, as Figure 7 , Figure 8 and Fig. 9As shown, a clockwork box 9 is arranged outside the first reduction box 8, and a clockwork assembly is arranged inside the clockwork box 9. The transmission end of the clockwork assembly is connected to the reduction teeth at the driving end of the first reduction box 8, and the tightening end of the clockwork assembly is connected to the tightening end head 901 arranged outside the first reduction box 8.

[0056] Specifically, a clockwork structure is adopted for the drive control of the adjustment component 5, and the conversion principle between mechanical energy and kinetic energy is utilized, so that the control is more convenient. It is only necessary to manually tighten the clockwork structure through the driving device within the predetermined stagnation time of the clockwork. For example, the clockwork is tightened once in 30 hours, and it is only necessary to manually tighten the clockwork structure once when the clockwork component runs for 25 hours to 28 hours. This method has a simple structure and is easy to control. It also reduces the hard costs generated by using some intelligent control equipment and avoids the complexity of related line connections.

[0057] In summary, by adjusting the drive of the mounting frame 2 and the transmission assembly 3 arranged on the mounting frame 2 by the adjustment component 5, the photovoltaic panel can be adaptively adjusted according to the position of the light. At the same time, during the rotation of the mounting frame 2, the panel surface of the photovoltaic panel can be intermittently cleaned by the brush plate 4 arranged on the transmission assembly 3, which can effectively improve the power generation performance of the photovoltaic panel. When the photovoltaic bracket is initially started, 6 o'clock in the morning is used as the starting point. Before 6 o'clock, the handheld motor can be used to tighten the steel sheet 907 in the clockwork box 9 by tightening the end 901. The operation starts at 6 o'clock, and the single operation cycle is 12 hours. The initial end of the reset operation is 18 o'clock in the afternoon. For the tightening of the clockwork component, it can be tightened and charged based on 2 to 5 hours before the energy of the clockwork component is fully released. The overall operation process of the photovoltaic bracket includes the following:

[0058] S1, the clockwork box 9 transmits the first reduction box 8 through the clockwork assembly, the first reduction box 8 performs the first reduction on the transmission of the clockwork assembly, and transmits the transmission connection between the adjustment box 6 and the first reduction box 8;

[0059] S2, the gear h1201 of the transmission connector transmits the gear i1202 through the chain c12. Since the gear i1202 and the gear g1103 are coaxial, when the gear i1202 is transmitted, the gear g1103 and the reduction gear in the second reduction box 7 are also transmitted;

[0060] S3, after the second reduction gearbox 7 has reduced speed for the second time, it drives the reversing adjustment member in the adjustment box 6, so that the mounting frame 2 performs a reciprocating rotation with a cycle of 24 hours, and the photovoltaic panel fixed on the mounting frame 2 can perform adaptive rotation following the different positions of the light;

[0061] S4. Based on the above step S2, while the gear g1103 and the gear i1202 rotate synchronously, the gear f1101 is driven to rotate through the chain b11, and the gear f1101 drives the gear a301 at the end of the transmission assembly 3 on the mounting frame 2 to rotate through the shaft b1102. The gear a301 at the end drives multiple linearly arranged gears a301 on both sides of the mounting frame 2 through the shaft a10 and the chain a302 to perform synchronous transmission;

[0062] S5. The transmission of chain a302 will drive the brush plate 4 to move along with the chain a302. During the movement of the brush plate 4, the dust on the surface of the photovoltaic panel will be cleaned. When the brush plate 4 moves to the bottom of the photovoltaic panel, when it encounters line equipment, it will be adaptively rotated and unfolded. After passing the line equipment, it will be reset by the return spring. After resetting, the surface of the photovoltaic panel will be cleaned again.

[0063] In order to ensure that the chain a302 can provide a better support effect for the brush plate 4 during the transmission of the transmission assembly 3, such as Figure 3 and Figure 4 As shown, the two sets of transmission components 3 are composed of multiple sets of gears a301 linearly arranged along the side ends of the mounting frame 2 and chains a302 nested on the multiple sets of gears a301 for synchronous transmission. The gears a301 at the ends of both sides of the mounting frame 2 are connected by an axle rod a10 set inside the mounting frame 2. The gear a301 at the end of the mounting frame 2 corresponds to the position of the gear f1101, and the gear f1101 is provided with axle rod b1102 connected to the gear a301.

[0064] Furthermore, since the brush plate 4 needs to cooperate with the transmission of the chain a302 to clean the photovoltaic panels, it is necessary to improve the support of the chain a302. The corresponding method is to set up multiple groups of linearly arranged gears a301. The multiple groups of gears a301 can provide support for different positions of the chain a302, fill the gaps between the chains a302, and enhance the stability between the chain a302 and the brush plate 4.

[0065] Based on the above, if Figure 4As shown, a connecting seat 303 with an integrated structure is provided on the inner side of the chain a302, a disc-shaped seat 304 for connecting the brush plate 4 is provided on the top of the connecting seat 303, and a return spring for resetting the disc-shaped seat 304 is provided inside the connecting seat 303. Considering the weight issue, the brush plate 4 can adopt a plastic plate with a light weight and bristles. In addition, considering that a line device or a line connection part is also provided at the bottom of the photovoltaic panel, the brush plate 4 adopts an independent two-part design, which are respectively installed on the chain a302 of the transmission assembly 3 on both sides of the mounting frame 2. A rotating structure is adopted between the brush plate 4 and the connecting seat 303, and the rotating structure also has the effect of automatic resetting. The disc-shaped seat 304 is connected to the connecting seat through a shaft member. On the rotating part at the bottom of 303, the interior of the connecting seat 303 can be a hollow structure, and the rotation limit of the disc-shaped seat 304 itself is located on the top circular opening of the connecting seat 303, and a rebound spring is arranged on the shaft body. Therefore, the rotation of the disc-shaped seat 304 will be constrained by the rebound spring. When the brush plate 4 rotates to the bottom of the mounting frame 2, if line equipment or line connection parts appear, the two groups of brush plates 4 will form a split structure through rotation. Under the premise of not affecting the transmission of the transmission component 3, relevant obstacles can be effectively avoided, and then they will automatically reset with the help of the rebound spring. The elastic force generated by the rebound spring is greater than the friction between the bristles of the brush plate 4 and the photovoltaic panel, which is optimal. The brush plate 4 can also be replaced with a sticky adhesive roller or a related component for easy cleaning of dust.

[0066] In order to allow the mounting frame 2 to perform a fixed angle reciprocating motion, such as Fig.10 and Fig.11 As shown, the above-mentioned reversing adjustment member includes two groups of gears c602 and gear d603 of the same size and meshing connection, and a gear b601 connected to the central part of the shaft member at the side end of the mounting frame 2. The gears c602 and d603 are symmetrically provided with half gears a604 and half gears b605 of the same size and corresponding to the meshing position of the gear b601 at one end, and the gear c602 is connected to the reduction teeth at the transmission end of the second reduction box 7.

[0067] Among them, when the above-mentioned reversing adjustment member is in operation, two conditions must also be met. First, it needs to cooperate with the continuous operation of the mainspring without any pauses. Second, during the continuous operation, the direction of operation needs to be intermittently adjusted, such as Fig.10 and Fig.11 As shown, gear c602 and gear d603 are of the same specification and are in a meshing state with each other. Both can be used as the driving end of the reversing adjustment member. In this application, gear c602 is used as the driving end, and gear c602 and gear d603 are provided with half gears a604 and half gears b605 of the same size and symmetrically arranged tooth patterns. At the same time, the reversing adjustment member also includes a gear b601 that is in a meshing position with the half gear a604 and the half gear b605.

[0068] According to the above content and the structure in the figure, it can be known that gear b601 is the core component that drives the mounting frame 2 to rotate, and the meshing movement between gear c602 and gear d603 realizes the reversal of half gear a604 and half gear b605 respectively. When the teeth on half gear a604 and half gear b605 respectively mesh with gear b601, the reversal of gear b601 can be realized, that is, the reversal of mounting frame 2. When the clockwork assembly keeps running continuously, mounting frame 2 will always perform reciprocating motion at a fixed angle. Based on the reversing angle, it is necessary to adapt the reversing adjustment member of corresponding size according to the actual situation of the photovoltaic bracket as a whole, and also to make targeted settings according to the number of teeth on the half gears.

[0069] like Figure 7 , Figure 8 and Fig. 9 As shown, the structure of the clockwork assembly specifically includes a gear e902 connected to the reduction tooth at the driving end of the first reduction box 8 through an axle, a rotating seat 903 meshing with the gear e902 for transmission, a ratchet 904 connected to the tightening end 901, and a limit bar 905 installed on the inner wall of the clockwork box 9 for limiting the rotation of the ratchet 904.

[0070] Among them, a tooth buckle 906 meshing with the gear e902 is arranged on the outer wall of one end of the rotating seat 903, and a rotating end a908 and a rotating end b909 are respectively arranged on the outer walls of the centers of the two ends of the rotating seat 903. A wound steel sheet 907 is arranged inside the rotating seat 903, and a connecting shaft is arranged on the ratchet 904. The connecting shaft passes through the interior of the rotating seat 903 through the rotating end b909 and is connected to the rotating end a908. The shaft body of the penetrating part of the connecting shaft will be connected to the steel sheet 907.

[0071] It should be noted that the operating principle of the mainspring assembly is the same as that of the mainspring structure of a clock, and both realize the overall transmission of the adjustment assembly 5 by tightening the steel sheet 907 and utilizing the energy released by the steel sheet 907 itself to drive the rotating seat 903 to rotate. At the same time, the tightening structure is also realized by the cooperation of the ratchet 904 and the limit bar 905, and the steel sheet 907 is tightened by the tightening end 901 located on the outside of the mainspring box 9.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
