Description

Technical Field

[0001] The utility model relates to the technical field of electric drivers, in particular to an electric push rod for photovoltaic steering. Background Art

[0002] Solar panels in the photovoltaic industry are the core structure and the key to receiving sunlight and converting it into electrical energy. In addition, in order to improve power generation efficiency, solar panels are usually placed facing the sun to ensure sufficient light reception.

[0003] Since the sun is constantly moving relative to a fixed point on the ground, solar panels installed at a certain location need to constantly change their angles to ensure they are better aligned with the sun, i.e., to achieve steering of the solar panels and improve power generation efficiency. Currently, the structures on the market for changing the angles of solar panels are divided into two types: manual and electric. The manual method involves manually pushing the angle of the solar panel through a push rod and locking the push rod after adjustment. However, this requires frequent adjustments by the operator, which increases labor intensity and poses a safety hazard. In addition, the adjustment process is a staged adjustment, which can lead to untimely adjustments. The other electric method involves setting an electric push rod between the solar panel and the mounting frame, and pushing the solar panel to extend and retract by the electric push rod, thereby achieving remote adjustment of the corresponding angle of the solar panel. Furthermore, the electric method can be adapted to a remote intelligent control system to achieve intelligent and real-time adjustment, with more timely adjustments and higher power generation efficiency. Although the above-mentioned electric method can already meet the steering adjustment requirements well, the commonly used electric push rods on the market, such as the push rod drive device disclosed in patent CN117097069A, include a driver and a push rod. The push rod is located beside the driver, and a driving source is superimposed on the bottom of the driver. The push rod includes a screw rod, a telescopic rod, a gear set, a rotating shaft and a housing assembly. The telescopic rod and the gear set are both located in the housing assembly. The telescopic rod is sleeved outside the screw rod and is threadedly connected to the screw rod. The screw rod is connected to the rotating shaft through the gear set. The driving source drives the rotating shaft to rotate. The side of the driving source is poorly connected to the fixed end of the housing assembly through the bracket. When in use, the driver controls the operation of the driving source, and the driving source drives the rotating shaft to rotate. The rotating shaft drives the screw rod to rotate to control the extension and retraction of the telescopic rod, thereby realizing the extension and retraction of the entire push rod. However, in actual usage scenarios, each push rod is configured with a corresponding drive structure, that is, each push rod is independently driven, which is costly. In addition, due to differences in product quality and subsequent control delays, the drive structures of different push rods installed on the same solar panel are prone to inconsistent actions, which can easily damage the solar panel after long-term use and affect its service life.

[0027] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To the attached Figure 4 The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.

[0028] Figure 1 This is a structural diagram of an embodiment of an electric push rod for photovoltaic steering according to the present utility model; Figure 2 This is a structural diagram of a preferred embodiment of the utility model after removing the outer shell; Figure 3 This is a cross-sectional view of a preferred embodiment of the present invention. Figure 1 、 Figure 2 as well as Figure 3As shown, the electric push rod for photovoltaic steering provided in this embodiment includes: a push rod 1 and a transmission box 2. A push rod 1 is equipped with a transmission box 2. The power of the driver is transmitted to the push rod 1 through the transmission box 2, and is converted into a linear push and pull force through the push rod 1 to form an electric push rod. At this time, the two ends of the electric push rod are respectively hinged to the solar panel and the mounting frame. The steering of the solar panel is achieved by the extension and retraction of the electric push rod to meet the photovoltaic angle adjustment requirements.

[0029] Specifically, the push rod 1 of the electric push rod includes a tube seat 11, a telescopic tube 12 and a screw assembly 13. During installation, one end of the telescopic tube 12 is installed on the tube seat 11 to realize the connection between the telescopic tube 12 and the tube seat 11. At the same time, the screw assembly 13 is installed in the telescopic tube 12 and one end passes through the tube seat 11 and extends out. The telescopic tube 12 is driven to be extended and retracted by the screw assembly 13, and then the solar panel is turned by the extension and retraction of the telescopic tube 12.

[0030] Specifically, the transmission box 2 is arranged at one end of the tube seat 11 of the push rod 1. In this case, the transmission box 2 is a double-headed transmission box 2, which has the ability to connect and drive at both ends and can realize the series connection of multiple transmission boxes 2. In addition, the transmission box 2 includes a force frame 21, a transmission shaft 22 and a gear assembly 23. During installation, the force frame 21 is installed on the end of the tube seat 11 away from the telescopic tube 12, thereby realizing the connection between the tube seat 11 and the force frame 21. At the same time, the middle part of the transmission shaft 22 is rotatably installed on the force frame 21. Preferably, a deep groove ball bearing is provided between the transmission shaft 22 and the force frame 21 to meet the use requirement of stable rotation of the transmission shaft 22 on the force frame 21. In addition, both ends of the transmission shaft 22 are extended outside the force frame 21, which provides conditions for the subsequent use as a power input structure and a power transmission structure. Furthermore, the screw assembly 13 extends through one end of the tube base 11 into the force frame 21, and a gear assembly 23 is provided between the transmission shaft 22 and the end of the screw assembly 13 extending into the force frame 21, so that the transmission shaft 22 can drive the screw assembly 13 to move through the gear assembly 23, thereby realizing the extension and retraction of the telescopic tube 12. In addition, the two ends of the transmission shaft 22 extending outside the force frame 21 are used as the power input shaft and the power output shaft, respectively, and in the two adjacent transmission boxes 2, the power output shaft of the front transmission box 2 is connected to the power input shaft of the rear transmission box 2. When multiple electric push rods are installed on the same solar panel, the transmission shafts 22 of the transmission boxes 2 of the multiple electric push rods can be connected in series, realizing the synchronous movement of multiple electric push rods located on the same solar panel, preventing the problem of damage to the solar panel due to asynchrony, and extending the service life. Preferably, a transmission connecting rod is provided between a power output shaft and a corresponding power input shaft of two adjacent transmission boxes 2, and the transmission connecting rod can realize the connection of the transmission shafts 22 of the two transmission boxes 2. Further preferably, universal joints are installed at both ends of the transmission connecting rod, so as to adapt to the installation error problem of the two interconnected transmission boxes 2, ensure that there will be no jamming or excessive wear problems during the transmission process, and the structural design is more reasonable.

[0031] More specifically, the transmission shafts 22 of the transmission boxes 2 corresponding to the multiple push rods 1 installed on the same solar panel are connected in series and then connected to the main shaft power of a driver, so that multiple electric push rods installed on the same solar panel can be driven by the same driver, thereby reducing the use of drivers and reducing costs while ensuring synchronous movement.

[0032] It is worth pointing out that since both ends of the transmission shaft 22 of the transmission box 2 of each electric push rod extend outside the force frame 21, in addition to one end of the transmission shaft 22 being used for power input and the other end being used for power output, both ends of the transmission shaft 22 can be used as power input shafts, that is, when the installation position space is limited, the appropriate end of the transmission shaft 22 can be selected according to the actual space to connect the driver, which improves the installation adaptability, makes the structure more flexible, and has fewer usage restrictions.

[0033] More specifically, adapter sleeves 24 are sleeved on both ends of the transmission shaft 22, and are used to connect to an external power structure through the adapter sleeves 24 to achieve power transmission. At this time, flat shaft holes 241 are opened at both ends of the adapter sleeve 24. At the same time, both ends of the transmission shaft 22 are flat shafts corresponding to the flat shaft holes 241. That is, the flat shafts at the ends of the transmission shaft 22 are inserted into the corresponding flat shaft holes 241 of the adapter sleeve 24, achieving circumferential limitation between the transmission shaft 22 and the adapter sleeve 24. Not only is the structure simple and easy to install, but it can also meet the needs of rotational power transmission.

[0034] More specifically, the telescopic tube 12 of the push rod 1 includes an inner tube 121 and an outer tube 122. In this case, the screw assembly 13 of the push rod 1 includes a screw 131 and a screw block 132. During installation, the outer tube 122 is sleeved outside the inner tube 121, and one end of the inner tube 121 extends outside the outer tube 122. A connecting seat is provided on the end of the inner tube 121 extending outside the outer tube 122, which facilitates hinged connection to a solar panel or mounting frame. In addition, a screw block 132 is installed at the other end of the inner tube 121, and the inner tube 121 and the screw block 132 can be fixed and locked by a threaded connection, so that the screw block 132 and the inner tube 121 can form a whole. In addition, the end of the outer tube 122 extending away from the inner tube 121 is installed on the tube base 11, achieving a fixed connection between the outer tube 122 and the tube base 11, so that the outer tube 122 serves as a relatively fixed structure and guides the installation and telescopic movement of the inner tube 121. Furthermore, the screw 131 is disposed within the inner tube 121 and threadedly connected to the screw block 132. One end of the screw 131 extends through the tube base 11 and into the force-bearing frame 21. It is worth noting that a circumferential limit is formed between the screw block 132 or one of the inner tube 121 and the outer tube 122. This prevents the screw block 132 from rotating when the screw 131 rotates, ensuring that the screw block 132 can move axially along the screw 131, thereby achieving telescopic movement of the inner tube 121 relative to the outer tube 122.

[0035] More specifically, a guide sleeve 14 is sleeved on one end of the screw rod 131 that passes through the tube seat 11, and a thrust ball bearing 15 is also mounted on the guide sleeve 14. The guide sleeve 14 maintains the stability of the screw rod 131 during rotation. At this time, the outer side of the thrust ball bearing 15 is mounted on the tube seat 11, meeting the rotational installation requirements of the screw rod 131 on the tube seat 11. At the same time, a compression nut 16 is threadedly connected to the end of the screw rod 131 where the guide sleeve 14 is mounted, and the compression nut 16 is mounted on one side of the guide sleeve 14 and compresses the guide sleeve 14, thereby achieving stable installation of the guide sleeve 14 and the thrust ball bearing 15 on the screw rod 131, thereby achieving stable installation of the screw rod 131 on the tube seat 11. In addition, the rotational connection between the screw rod 131 and the tube seat 11 via the thrust ball bearing 15 can effectively withstand axial loads, ensure smooth rotation of the screw rod 131, and guarantee operational stability and reliability.

[0036] More specifically, the gear assembly 23 is a bevel gear set, and the two bevel gears of the bevel gear set are respectively installed on the screw 131 and the transmission shaft 22. At this time, the screw 131 extends to one end inside the force frame 21 and is located on the side of the clamping nut 16 away from the guide sleeve 14, and one of the bevel gears of the bevel gear set is sleeved. The transmission shaft 22 is located in the force frame 21 and is sleeved with another bevel gear of the bevel gear set, so that when the transmission shaft 22 rotates, the power can be transmitted to the screw 131 through the bevel gear set, thereby meeting the telescopic requirements of the electric push rod, and at the same time, the arrangement directions of the screw 131 and the transmission shaft 22 can be perpendicular to each other, meeting the use requirements of the transmission shaft 22 to realize power input and output from the side of the force frame 21. It is worth noting that a threaded locking hole is provided on the end face of the screw 131 on which the bevel gear is installed. When the corresponding bevel gear is sleeved on the screw 131, a screw can be passed through the bevel gear to connect the threaded locking hole, thereby realizing the rapid installation of the bevel gear on the screw 131. The structure is simple and the disassembly and assembly are convenient.

[0037] More specifically, the rectangular frame 21 supporting the tube base 11 not only enhances overall structural strength but also provides ample internal space for mounting gear assembly 23 and other components. Furthermore, the frame 21 is constructed of 45-gauge steel, further ensuring structural strength, increased load-bearing capacity, and a longer service life. Furthermore, the readily available material and sophisticated, convenient processing techniques reduce manufacturing and operating costs.

[0038] More specifically, a tail end sheet metal part 3 is also provided on the force frame 21. At this time, one end of the tail end sheet metal part 3 is connected to the end of the force frame 21 away from the mounting pipe seat 11, and a hinge hole 31 is opened on the other end of the tail end sheet metal part 3, that is, one end of the formed electric push rod is connected to the external structure through the connecting seat on the inner tube 121, and the other end is connected to the external structure through the hinge hole 31 on the tail end sheet metal part 3, which meets the requirements of installation and use of the electric push rod between the solar panel and the mounting frame.

[0039] More specifically, the tail end sheet metal part 3 is a stamped and bent plate part. In this case, one side of the tail end sheet metal part 3 is arranged in a "J" shape. That is, after the plate is stamped and formed, it is bent multiple times to form a structure similar to the "J" shape. This not only facilitates processing, but also increases the structural strength of the tail end sheet metal part 3, maintaining the stability and reliability of the electric push rod after installation. In addition, the open end of the tail end sheet metal part 3 is connected to the force frame 21, so that both sides of the tail end sheet metal part 3 have structures connected to the force frame 21, which improves the installation stability of the tail end sheet metal part 3 and makes the structural design more reasonable.

[0040] More specifically, connecting holes are provided on the two oppositely arranged end surfaces of the force frame 21 for mounting the tube seat 11 and the tail end sheet metal 3. At this point, a threaded fastener is installed in the connecting hole, and the two ends of the threaded fastener are connected to the tube seat 11 and the tail end sheet metal 3, respectively. This allows the threaded fastener to simultaneously connect the tube seat 11 and the tail end sheet metal 3 to the force frame 21, making assembly and disassembly more convenient. It is worth noting that the frame-in-frame connection holes are provided in multiple groups, preferably four groups, which can be distributed at the four corners of the force frame 21, thereby increasing the connection strength between the tube seat 11 and the tail end sheet metal 3 and making the force more even.

[0041] More specifically, a housing 4 is provided outside the tube base 11, the stress frame 21, and the tail end sheet metal 3. In this case, the housing 4 is a split structure, which facilitates assembly and disassembly of the housing 4. Furthermore, the housing 4 is further divided into a front housing 41 and a rear housing 42. The front housing 41 is arranged in a cylindrical shape. During installation, the front housing 41 is positioned outside the tube base 11 and the stress frame 21, and the rear housing 42 is positioned outside the tail end sheet metal 3. This completely encloses the tube base 11, the stress frame 21, and the tail end sheet metal 3, providing enhanced external protection. Furthermore, one end of the rear housing 42 is embedded in the opening of the front housing 41. Simultaneously, the end of the rear housing 42 embedded in the front housing 41 is connected to the stress frame 21 by a snap-fit ​​connection. Preferably, a snap block is provided on the rear housing 42, and a snap hole is provided on the stress frame 21. The snap-fit ​​connection is achieved through the cooperation of the snap block and the snap hole. In addition, a locking hole is opened on the side wall of the front shell 41, and a screw is passed through the locking hole and threadedly locked with the force frame 21, thereby achieving stable installation of the front shell 41 on the force frame 21, thereby ensuring that the shell 4 can be stably installed outside the tube seat 11, the force frame 21 and the tail end sheet metal 3.

[0042] Figure 4 This is a structural diagram of a tube seat of a preferred embodiment of the utility model. Figure 2 、 Figure 3 as well as Figure 4 As shown, a groove 111 is formed at the end of the tube base 11 mounted on the force-bearing frame 21. A deep groove ball bearing is embedded in the groove 111, achieving concealed installation of the deep groove ball bearing. Furthermore, a plurality of hollow holes 112 are formed in the side wall of the tube base 11 at the end where the groove 111 is formed, thereby reducing the overall weight of the tube base 11, saving materials, and lowering costs.

[0043] The photovoltaic steering electric push rod provided in this embodiment includes a push rod 1 and a transmission box 2; a transmission shaft 22 with both ends extending outside the force frame 21 is set in the transmission box 2 connected to the screw assembly 13 of the push rod 1, so that the two ends of the transmission shaft 22 can be used as a power input shaft and a power output shaft respectively, and a gear assembly 23 is provided between the transmission shaft 22 and the screw assembly 13 to meet the use requirements of the transmission box 2 to drive the push rod 1 to extend and retract, and it can also enable the transmission shaft 22 of the transmission box 2 of the push rod 1 installed on the same solar panel to be connected in series and to the same driver, thereby realizing the synchronous movement of multiple electric push rods installed on the same solar panel, which can prevent the damage of the solar panel caused by asynchrony during use and extend the service life, and can also realize the synchronous driving of multiple electric push rods on the same solar panel by one driver, reducing the use of drivers, reducing costs, and facilitating popularization and use.
