[0048] In photovoltaic power generation, the angle of the photovoltaic panel is generally adjusted by a controller. The premise for the controller to accurately control the photovoltaic panel is that the signal receiving strength of the signal receiving antenna connected to the controller must be guaranteed. The inventor of the present application found that when the signal receiving antenna is installed and fixed, its position will remain unchanged. As the photovoltaic panel and the photovoltaic tracking bracket rotate, they will cause a certain amount of obstruction to the signal receiving antenna, thereby affecting the signal reception effect.

[0049] Based on this, an embodiment of the present application provides a photovoltaic installation mechanism that can solve the above problems. The photovoltaic installation mechanism provided by an embodiment of the present application will be described in detail below in conjunction with the accompanying drawings.

[0050] See also Figures 1 to 3 As shown, a photovoltaic installation mechanism provided by an embodiment of the present application includes a crossbeam 110 and a lifting unit 210 connected to the crossbeam 110 in a transmission manner. A rotating bracket 120 for mounting a photovoltaic panel 130 is provided at at least one end of the crossbeam 110 along its own axial direction, and the rotating bracket 120 moves synchronously with the crossbeam 110; a lifting platform 220 for mounting a signal receiving antenna 230 is provided at the output end of the lifting unit 210; wherein, when the crossbeam 110 rotates with the horizontal direction as the axis, the lifting unit 210 converts the rotation of the crossbeam 110 into the movement of the lifting platform 220 in the vertical direction, so that the receiving end of the signal receiving antenna 230 is located above the photovoltaic panel 130. It can be understood that a controller 600 is also connected to the crossbeam 110, and the controller 600 is connected to the signal receiving antenna 230 in a communication manner.

[0051] In the photovoltaic installation mechanism, when the angle of the photovoltaic panel 130 installed on the rotating bracket 120 is adjusted, the lifting unit 210 converts the rotation of the beam 110 into the movement of the lifting platform 220 in the vertical direction. For example, when the rotating bracket 120 rotates from east to west, the lifting unit 210 will drive the lifting platform 220 to move up, that is, the signal receiving antenna 230 located on the lifting platform 220 moves up, so that the signal receiving antenna 230 is always in the highest position and is located above the photovoltaic panel 130, reducing the possibility of the signal receiving antenna 230 being blocked by the photovoltaic panel 130 due to the rotation of the photovoltaic bracket, and ensuring the strength of signal reception. After the geographic information signal is received by the signal receiving antenna 230, the information is transmitted to the controller 600, so that the controller 600 can accurately control the rotation angle of the photovoltaic panel 130. Among them, the controller 600 can be clamped on the outer peripheral surface of the beam 110 through a clamp-type mounting frame. The signal receiving antenna 230 can be fixedly connected to the upper surface of the lifting platform 220 by bolts and other components.

[0052] See also Figure 3 As shown, in one embodiment, the lifting unit 210 includes a first transmission wheel 211 sleeved on the crossbeam 110 and a first meshing portion 212 meshed with the first transmission wheel 211 for transmission, and the transmission direction of the first meshing portion 212 is perpendicular to the transmission direction of the first transmission wheel 211; the lifting platform 220 is connected to the output end of the first meshing portion 212. Through the cooperation of the first transmission wheel 211 and the first meshing portion 212, the rotational power of the crossbeam 110 is transmitted to the lifting platform 220, so that the lifting platform 220 is lifted and lowered.

[0053] See also Figure 3 As shown, in one embodiment, the first transmission wheel 211 is configured as a first bevel gear, and the first meshing portion 212 is configured as a second bevel gear; the lifting unit 210 also includes a screw 213 connected to the second bevel gear and a lifting block 214 spirally connected to the screw 213, and the screw 213 is used to drive the lifting block 214 to move in the vertical direction; the lifting platform 220 is connected to the lifting block 214. In this way, the rotation of the crossbeam 110 will drive the first bevel gear to rotate synchronously, thereby driving the second bevel gear and the screw 213 connected to the second bevel gear to rotate, thereby driving the lifting block 214 and the lifting platform 220 to move upward. Among them, the first bevel gear can be fixedly connected to the lower end of the screw 213, and the second bevel gear is sleeved on the crossbeam 110. Further, the lifting block 214 is connected to a lifting rod 215 on one side along the axial direction of the crossbeam 110, and the end of the lifting rod 215 away from the lifting block 214, that is, the upper end, is connected to the lifting platform 220.

[0054] like Figure 1As shown, in one embodiment, the lifting unit 210 includes a second mounting shell 216, and the first bevel gear, the second bevel gear, the screw 213 and other components are all accommodated in the second mounting shell 216, the crossbeam 110 is arranged in the second mounting shell 216, and the lifting block 214 is slidably connected to the inner wall of the second mounting shell 216. The second mounting shell 216 has a certain protective effect on the transmission components such as the first bevel gear, the second bevel gear and the screw 213, thereby improving the waterproof and dustproof capabilities of each component, thereby improving their service life. In one embodiment, the crossbeam 110 is rotatably connected to the right side wall of the second mounting shell 216, wherein a bearing may be provided on the right side wall, and the crossbeam 110 is connected to the inner ring of the bearing. In this way, the crossbeam 110 is rotatably connected to the second mounting shell 216. In one embodiment, a bearing is provided on the upper side wall of the crossbeam 110, and the screw 213 is connected to the inner ring of the bearing.

[0055] In addition to the bevel gear matching form, in other embodiments, the first transmission wheel 211 and the first meshing portion 212 may also be a spur gear, and the first meshing portion 212 may be a rack extending in the vertical direction. Through the meshing transmission of the gear and the rack, the rotation of the gear is converted into the movement of the rack, thereby driving the lifting platform 220 connected to the rack to move upward.

[0056] See also Figure 4 As shown, in one embodiment, the photovoltaic installation mechanism further includes a first rotating drive member 240, and the first rotating drive member 240 is used to drive the crossbeam 110 to rotate. It can be understood that the first rotating drive member 240 is in communication connection with the controller 600, for example, the two are electrically connected, so that the first rotating drive member 240 can receive instructions from the controller 600 to control the rotation of the crossbeam 110. The first rotating drive member 240 can use a forward and reverse motor. During the day, the first rotating drive member 240 rotates forward, thereby driving the rotating bracket 120 and the photovoltaic panel 130 to rotate slowly from east to west; and at night, the first rotating drive member 240 reverses, so that the rotating bracket 120 and the photovoltaic panel 130 return to the initial position angle in the morning.

[0057] See also Figure 4 As shown, in one embodiment, the first rotary drive member 240 is disposed on one side of the cross beam 110 along its radial direction; a transmission wheel set is disposed between the first rotary drive member 240 and the cross beam 110, and the transmission wheel set transmits the rotary power of the first rotary drive member 240 to the cross beam 110. By arranging the first rotary drive member 240 on one side of the cross beam 110 in the radial direction, the space occupied by the two in the axial direction can be reduced.

[0058] See also Figure 4As shown, in one embodiment, the transmission wheel set includes a third bevel gear 241 respectively connected to the first rotating driving member 240 and a fourth bevel gear 242 respectively sleeved on the cross beam 110, and the third bevel gear 241 is meshed with the fourth bevel gear 242 for transmission. It can be seen that the output direction of the first rotating driving member 240 is perpendicular to the rotation direction of the cross beam 110, and the power of the first rotating driving member 240 is transmitted to the cross beam 110 on one side through the cooperation of the third bevel gear 241 and the fourth bevel gear 242.

[0059] In other embodiments, the transmission wheel set may also be two meshing spur gears, the axial direction of the two spur gears is parallel to the axial direction of the beam 110, and the power of the first rotating drive member 240 is transmitted to the beam 110 on one side through the two spur gears.

Since the signal receiving antenna 230 is exposed to the air for a long time, in order to avoid interference of signal reception caused by dust accumulated on the surface, the dust accumulated on the surface of the signal receiving antenna 230 is cleaned by the dust removal unit 310 to improve the signal receiving strength of the signal receiving antenna 230.

[0061] See also Figure 5 As shown, in one embodiment, the dust removal unit 310 includes a dust removal fan 311, and the air outlet of the dust removal fan 311 faces the signal receiving antenna 230. The dust on the surface of the signal receiving antenna 230 is blown away by the dust removal fan 311 to achieve a cleaning operation of the signal receiving antenna 230. In other embodiments, the dust removal unit 310 can also be a dust removal brush.

[0062] See also Figure 5 As shown, in one embodiment, taking the dust removal unit 310 including a dust removal fan 311 as an example, the dust removal fan 311 includes a plurality of dust removal fans, and the dust removal unit 310 also includes a dust removal plate 312, and the plurality of dust removal fans 311 are arranged on the dust removal plate 312 at intervals in the vertical direction. By providing a plurality of dust removal fans 311, the cleaning area of ​​the signal receiving antenna 230 can be increased, and the dust removal capacity and dust removal effect can be improved.

[0063] See also Figure 5 As shown, in one embodiment, the dust removal fans 311 include two groups, each group of dust removal fans 311 includes at least one dust removal fan 311, and the two groups of dust removal fans 311 are respectively located on opposite sides of the signal receiving antenna 230. For example, in the embodiment shown in the drawings, the dust removal fans 311 are located on opposite sides of the signal receiving antenna 230 along the axial direction of the beam 110.

[0064] See also Figure 5 As shown, in one embodiment, a second rotating driving member 320 is provided on the lifting platform 220, and the second rotating driving member 320 is used to drive the dust removal unit 310 to rotate around the signal receiving antenna 230. The dust removal unit 310 may specifically include a dust removal fan 311, and by providing the second rotating driving member 320, the dust removal fan 311 is driven to rotate, thereby generating air flow to blow away dust and other debris on the surface of the signal receiving antenna 230. In other embodiments, the dust removal fan 311 may also have a built-in battery, and the built-in battery drives the dust removal fan 311 to rotate.

[0065] See also Figure 5 As shown, in one embodiment, the output end of the second rotary driving member 320 is connected to a rotating plate 330, and the dust removal unit 310 is disposed on the rotating plate 330. The dust removal unit 310 may specifically include a dust removal plate 312 and a dust removal fan 311 disposed on the dust removal plate 312, the dust removal plate 312 is fixedly connected to the rotating plate 330, and the second rotary driving member 320 drives the dust removal plate 312 to rotate through the rotating plate 330, and then the dust and other debris on the surface of the signal receiving antenna 230 are blown away by the dust removal fan 311.

[0066] See also Figure 5 and Figure 6 As shown, in one embodiment, a limit portion 340 is connected between the dust removal unit 310 and the rotating plate 330, and the lifting platform 220 is provided with a matching portion 350, and the limit portion 340 is slidably connected to the matching portion 350. The matching portion 350 can be specifically an arc groove. When the dust removal fan 311 is provided on both sides of the signal receiving antenna 230, correspondingly, a symmetrical arc groove is opened on the lifting platform 220.

[0067] like Figure 2B As shown, in one embodiment, a cavity 221 is provided inside the lifting platform 220 for accommodating the rotating plate 330. The output end of the second rotating driving member 320 is a transmission rod, the upper surface of which is connected to the rotating plate 330, and the upper surface of the rotating plate 330 is symmetrically provided with a limiting portion 340 such as a limiting rod, and the limiting rod is slidably connected with a matching portion 350 such as an arc groove provided on the lifting platform 220. The upper end of the limiting rod is fixedly connected to the dust removal plate 312, and a plurality of dust removal fans 311 are evenly distributed and fixed to the side wall of the dust removal plate 312.

[0068] Since the signal receiving antenna 230 is exposed to the air for a long time, in order to prevent dust accumulated on the surface from interfering with signal reception, the second rotating driving member 320 will work regularly, and the rotational power of the second rotating driving member 320 is transmitted to the dust removal plate 312 through the rotating plate 330 and the limit rod, thereby driving the dust removal plate 312 and the dust removal fan 311 disposed inside the dust removal plate 312 to rotate, generating air flow, thereby blowing away the dust accumulated on the surface of the signal receiving antenna 230. The second rotating driving member 320 uses a forward and reverse motor, so that the dust removal unit 310 can rotate clockwise or counterclockwise, and the dust removal area can be increased while changing the dust removal area.

[0069] like Figure 2B As shown, in one embodiment, a fourth mounting shell 360 is disposed on the lower surface of the rotating plate 330, and the second rotating driving member 320 is accommodated in the fourth mounting shell 360. By disposing the second rotating driving member 320 in the fourth mounting shell 360, the fourth mounting shell 360 can play a waterproof and dustproof effect, thereby improving the protection performance of the second rotating driving member 320.

[0070] See also Figure 2B and Figure 7 As shown, in one embodiment, a protection unit 410 is provided on the lifting platform 220, and the protection unit 410 can shield or expose the signal receiving antenna 230. The protection unit 410 can be covered on the outside of the signal receiving antenna 230, thereby avoiding the risk of damage to the signal receiving antenna 230 caused by storms or other severe weather, greatly extending the service life of the signal receiving antenna 230, and ensuring the reliability of the signal receiving antenna 230.

[0071] See also Figure 7As shown, in one embodiment, the protection unit 410 includes two protective shells 411 respectively arranged on both sides of the signal receiving antenna 230, at least one protective shell 411 can be close to the other protective shell 411 to form a closed space that isolates the signal receiving antenna 230 from the outside; and at least one protective shell 411 can be away from the other protective shell 411 to expose the signal receiving antenna 230. For example, in the embodiment shown in the accompanying drawings, the two protective shells 411 can be close to each other or away from each other. When the two are close to each other and docked together, a closed space is formed and covered outside the signal receiving antenna 230, thereby protecting the signal receiving antenna 230. When the two protective shells 411 are away from each other, the space between the two protective shells 411 gradually increases, so that the signal receiving antenna 230 can be exposed, and the protective shells 411 no longer block the signal receiving antenna 230, thereby ensuring the signal receiving strength of the signal receiving antenna 230. It can be understood that the two protective shells 411 have the same structure, and the upper and lower surfaces are flush, that is, they are on the same horizontal plane, ensuring the reliability of the closed space formed by the two. When encountering severe weather such as strong winds and rainstorms, it can provide better protection for the signal receiving antenna 230 and avoid damage to the signal receiving antenna 230.

[0072] See also Figure 2B and Figure 7 As shown, in one embodiment, at least one protective shell 411 is connected to a protective drive member 412, and the protective drive member 412 is used to drive the corresponding protective shell 411 to move in the horizontal direction. For example, in the embodiment shown in the accompanying drawings, two protective shells 411 are connected to protective drive members 412, so that the two can be synchronously moved closer or farther away. When encountering strong winds and rainstorms, the protective shells 411 can be driven to move by the protective drive member 412, so that the two protective shells 411 are docked and covered on the outside of the signal receiving antenna 230, so as to protect the signal receiving antenna 230 and prevent it from being damaged.

[0073] In other embodiments, the protective driving member 412 may be provided on only one of the protective shells 411 , and the other protective shell 411 may be relatively fixed, and the signal receiving antenna 230 may be shielded or exposed by moving one of the protective shells 411 closer to or farther from the other protective shell 411 .

[0074] See also Figure 7 As shown, in one embodiment, the protection drive member 412 and the protection shell 411 are respectively located on both sides of the lifting platform 220 in the vertical direction. For example, in the embodiment shown in the figure, the protection drive member 412 is arranged on the lower surface of the lifting platform 220, and the protection shell 411 is arranged on the upper surface of the lifting platform 220. By arranging the two on both sides of the lifting platform 220 in the vertical direction, the space occupied by the two in the horizontal direction can be reduced.

[0075] See also Figure 7 As shown, the lifting platform 220 is provided with a first mounting shell 413, the protective driving member 412 is provided in the first mounting shell 413, and the output end of the protective driving member 412 extends out of the first mounting shell 413. The first mounting shell 413 is fixedly provided on the lower surface of the lifting platform 220, for example, the left end and the right end of the lower surface of the lifting platform 220 are both provided with the first mounting shell 413, the protective driving member 412 is fixed in the first mounting shell 413, and the output end of the protective driving member 412 passes through the side wall of the first mounting shell 413 and extends out of the first mounting shell 413. A mounting block is fixed to the output end of the protective driving member 412, and the above-mentioned protective shell 411 is fixed to the upper side wall of the mounting block. Figure 2B As shown, in one embodiment, the protective shell 411 is slidably connected to the lifting platform 220 in the horizontal direction, for example, the lower side wall of the protective shell 411 is slidably connected to the upper side wall of the lifting platform 220. In one embodiment, the protective drive member 412 can be an electric push rod. In other embodiments, the protective drive member 412 can also be a linear motor, a telescopic cylinder, etc.

[0076] like Figure 1 As shown, in one embodiment, the rotating bracket 120 is provided with a receiving groove, and the photovoltaic panel 130 is fixedly arranged in the receiving groove. By setting the photovoltaic panel 130 in the rotating bracket 120, the fixing effect of the photovoltaic panel 130 can be improved, and the side wall of the receiving groove can also isolate the side wall of the photovoltaic panel 130 from the outside world, thereby achieving a certain protective effect.

[0077] like Figure 1 As shown, in some embodiments, the photovoltaic installation mechanism further includes a plurality of spaced support frames for supporting the crossbeam 110, and the support frames include support rods 523 and support plates 524 connected to the upper ends of the support rods 523. The lower end of the support frame, for example, the lower end of the support rod 523, is provided with a first mounting plate 525, and the first mounting plates 525 can be provided on both radial sides of each support rod 523. The first mounting plates 525 can be L-shaped, and threaded holes are provided on the first mounting plates 525, so that the first mounting plates 525 can be fixed to the ground by first fasteners 526, such as bolts, etc., thereby fixing the support frame to the ground, that is, fixing the photovoltaic installation mechanism to the ground.

[0078] For example, Figure 1 In the illustrated embodiment, the photovoltaic installation mechanism includes a first support frame 510 and two second support frames 520, and the two second support frames 520 can be symmetrically arranged at both ends of the first support frame 510 along the axial direction of the beam 110. The first support frame 510 and the second support frame 520 respectively support different positions of the beam 110, thereby improving the reliability of the photovoltaic panel 130.

[0079] like Figure 1 As shown, in one embodiment, the first rotating driving member 240 for driving the cross beam 110 to rotate is accommodated in the third mounting shell 243, and the third mounting shell 243 is fixed above the first support frame 510. A cross plate is fixedly connected to the upper surface of the second support frame 520, and a limit block 521 is fixedly connected to the upper surface of the cross plate. The axial ends of the cross beam 110 can be rotatably mounted in the limit blocks 521. The axial ends of the cross beam 110 are supported by providing the limit blocks 521, thereby improving the running stability of the cross beam 110. For example, a bearing is disposed in the limit block 521, and the axial ends of the cross beam 110 are rotatably connected to the inner ring of the bearing. In this way, the rotation of the cross beam 110 relative to the limit block 521 is realized.

[0080] like Figure 1 As shown, in one embodiment, the two axial ends of the beam 110 are also connected to fixed blocks 522, and one end of the fixed block 522 facing the rotating bracket 120 is connected to a reinforcement unit. The connection strength between the rotating bracket 120 and the beam 110 is enhanced by the reinforcement unit, and the support stability of the rotating bracket 120 and the photovoltaic panel 130 is improved. Specifically, the reinforcement unit includes a second cross plate 531 and a plurality of reinforcement frames 532, the second cross plate 531 is connected to a side surface of the fixed block 522 away from the cross beam 110, the reinforcement frame 532 is arranged on a side surface of the second cross plate 531 away from the cross beam 110, and the plurality of reinforcement frames 532 are evenly distributed along the axial direction of the beam 110, and the upper surface of the reinforcement frame 532 is fixedly connected to the lower surface of the rotating bracket 120.

[0081] like Figure 1 As shown, in some embodiments, a fixing tube 512 is sleeved on the upper end of the first support frame 510, and a first horizontal plate 511 is fixedly connected to one side surface of the fixing tube 512 along the axial direction of the cross beam 110, and the lifting unit 210 is arranged on the first horizontal plate 511. Figure 1 In the illustrated embodiment, the right side of the fixed tube 512 is connected to the first transverse plate 511 .

[0082] In the above-mentioned photovoltaic installation mechanism, the axial direction of the beam 110 can be north-south. When the sun just comes out in the morning, the rotating bracket 120 and the photovoltaic panel 130 are tilted toward the east; after the signal receiving antenna 230 receives the geographic information and other signals, it transmits the information to the controller 600. The controller 600 controls the first rotating drive member 240 to work, and through the power transmission of the aforementioned third bevel gear 241 and the fourth bevel gear 242, the beam 110 is driven to rotate, and then the rotating bracket 120 connected to the beam 110 and the photovoltaic panel 130 installed on the rotating bracket 120 are driven to rotate synchronously from east to west, so that the photovoltaic panel 130 is always facing the sun, and the photovoltaic panel 130 receives the maximum area of ​​light, thereby increasing the photovoltaic power generation. During the rotation of the crossbeam 110, through the cooperation of the aforementioned first bevel gear, second bevel gear, screw 213 and lifting block 214, the lifting platform 220 is in an ascending motion during the rotation of the rotating bracket 120 from east to west, so that the signal receiving antenna 230 arranged on the lifting platform 220 is always moving upward, so that the signal receiving antenna 230 is always kept at the highest position and is located above the photovoltaic panel 130 (the above here refers to the difference in height between the signal receiving antenna 230 and the photovoltaic panel 130, and the signal receiving antenna 230 can be located obliquely above the photovoltaic panel 130), so the signal receiving antenna 230 will not be blocked by the rotating bracket 120 and the photovoltaic panel 130 to affect the signal reception, thereby improving the strength of its signal reception, thereby accurately controlling the rotation angle of the rotating bracket 120 through the controller 600.

[0083] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
