Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to an intelligent balcony photovoltaic system. Background Technology

[0002] With the development of renewable energy technologies, photovoltaic power generation systems, as a clean and efficient energy solution, have gradually entered the lives of ordinary residents. In particular, balcony photovoltaic systems, due to their advantages such as convenient installation and no need to occupy extra space, have become an important way to utilize solar energy in urban residences.

[0003] First, considering the installation location of balcony photovoltaic systems—which extend outwards onto the balcony—there are potential safety hazards when facing severe weather conditions (such as strong winds and hail). Second, most current balcony photovoltaic systems use fixed bracket designs, which cannot be adjusted in real time according to changes in the sun's position to maximize light energy absorption efficiency, resulting in low energy conversion efficiency. Although there are some balcony photovoltaic power generation systems with adjustable brackets on the market, they often require manual adjustment, and the adjustment range is limited, making operation inconvenient and failing to meet users' needs for automation and efficient power generation.

[0004] Therefore, how to provide an intelligent balcony photovoltaic system that can automatically adjust the angle of photovoltaic modules is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent balcony photovoltaic system that solves the technical problem that the angle of existing balcony photovoltaic systems is inconvenient to adjust.

[0006] To achieve the above objectives, this utility model provides an intelligent balcony photovoltaic system, comprising:

[0007] The balcony railing has multiple reinforcing bars arranged horizontally and parallel to each other.

[0008] A photovoltaic module, wherein a first connecting rod and a second connecting rod are respectively provided on the upper and lower edges of the photovoltaic module;

[0009] Two linear guide rails are vertically and parallelly fixedly installed on the reinforcing rod;

[0010] Two upper sliding modules are provided, each of which is slidably disposed on the upper end of the corresponding linear guide rail. The upper sliding module is rotatably connected to the first connecting rod via a first rotating shaft.

[0011] Two sliding modules are provided, each of which is slidably disposed at the lower end of the corresponding linear guide rail.

[0012] The telescopic bracket has its two ends rotatably connected to the second connecting rod via a second rotating shaft and to the lower sliding module via a third rotating shaft, respectively.

[0013] The control unit, the upper sliding module and the lower sliding module are both signal connected to the control unit.

[0014] Preferably, the linear guide rail has a groove along its length on the side opposite to the balcony railing, and locking holes symmetrically connected to the groove are provided on the linear guide rail.

[0015] Preferably, the upper sliding module includes an upper housing with a through hole to allow the upper housing to be fitted onto the outside of the linear guide rail. A first motor and an upper transmission track are disposed inside the upper housing. One end of the upper transmission track is fixedly connected to the upper outer side of the linear guide rail, and the other end is fixedly connected to the bottom outer side of the upper housing. The shaft of the first motor is provided with an upper gear that meshes with the upper transmission track. The first motor is used to control the up-and-down movement of the upper housing.

[0016] Preferably, the upper sliding module further includes a first electromagnetic latch, which is used to cooperate with the locking hole to lock the upper housing. A first bracket is provided on the outer side of the upper housing, and the first bracket is rotatably connected to the first connecting rod through the first rotating shaft.

[0017] Preferably, the lower sliding module includes a lower housing, which is embedded in the groove of the linear guide rail. A second motor and a lower transmission track are disposed inside the lower housing. One end of the lower transmission track is fixedly connected to the upper inner side of the linear guide rail, and the other end is fixedly connected to the bottom outer side of the lower housing. The shaft of the second motor is provided with a lower gear that meshes with the lower transmission track. The second motor is used to control the up and down movement of the lower housing.

[0018] Preferably, the sliding module further includes a second electromagnetic latch, which is used to cooperate with the locking hole to lock the lower housing. A second bracket is provided on the outer side of the lower housing, and the second bracket is rotatably connected to the telescopic bracket through the third rotating shaft.

[0019] Preferably, the telescopic bracket includes a fixed rod and a sliding rod, wherein the fixed rod is sleeved on the outside of the sliding rod.

[0020] Preferably, both the first motor and the second motor are servo motors.

[0021] Preferably, the linear guide rail is provided with limit blocks at both the upper and lower ends.

[0022] Compared to the aforementioned background technology, the intelligent balcony photovoltaic system provided by this utility model has a control unit that sends commands to the upper and lower sliding modules to drive them to slide up and down along a linear guide rail, thereby controlling the tilt angle of the photovoltaic modules. When the upper and lower sliding modules slide down, the telescopic bracket unfolds; when the upper and lower sliding modules slide up, the telescopic bracket retracts. Furthermore, in the event of strong winds or hail, the control unit controls the upper and lower sliding modules to slide upwards synchronously, causing the telescopic bracket to fully retract, thus preventing damage to the photovoltaic modules. In summary, the intelligent balcony photovoltaic system provided by this application can automatically adjust the tilt angle of the photovoltaic modules, improving energy conversion efficiency. At the same time, in the event of strong winds or hail, the photovoltaic modules retract, reducing the damage rate. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] See Figure 1 , Figure 9 and Figure 10 This application provides an intelligent balcony photovoltaic system, including a balcony railing 1 with multiple horizontally parallel reinforcing rods 4; a photovoltaic module 5 with a first connecting rod 8 and a second connecting rod 10 corresponding to the upper and lower edges of the photovoltaic module 5; two linear guide rails 3, which are vertically and parallelly fixedly installed on the reinforcing rods 4; two upper sliding modules 2, each of which is slidably disposed on the upper end of the corresponding linear guide rail 3, and the upper sliding module 2 is rotatably connected to the first connecting rod via a first rotating shaft; two lower sliding modules 7, each of which is slidably disposed on the lower end of the corresponding linear guide rail 3; a telescopic bracket 9, the two ends of which are rotatably connected to the second connecting rod 10 via a second rotating shaft and to the lower sliding module 7 via a third rotating shaft; and a control unit, with both the upper sliding modules 2 and the lower sliding modules 7 connected to the control unit via signals.

[0039] In other words, the control unit sends commands to the upper sliding module 2 and the lower sliding module 7 to drive the upper sliding module 2 and the lower sliding module 7 to slide up and down along the linear guide rail 3, thereby controlling the tilt angle of the photovoltaic module 5.

[0040] When the upper sliding module 2 slides downward and the lower sliding module 7 slides downward, the telescopic bracket 9 unfolds, the tilt angle of the photovoltaic module 5 increases, and it approaches the vertical plane, as shown. Figure 10 As shown.

[0041] When the upper sliding module 2 slides upward and the lower sliding module 7 slides upward, the telescopic bracket 9 retracts, the tilt angle of the photovoltaic module 5 decreases, and it approaches the horizontal plane. Figure 9 As shown.

[0042] When encountering gale-force winds or hail, the control unit controls the upper sliding module 2 and the lower sliding module 7 to slide upwards synchronously, causing the telescopic bracket 9 to fully retract, thereby preventing damage to the photovoltaic modules. In summary, the intelligent balcony photovoltaic system provided in this application can automatically adjust the tilt angle of the photovoltaic modules to improve energy conversion efficiency. At the same time, when encountering gale-force winds or hail, the photovoltaic modules 5 retract to reduce the damage rate.

[0043] Based on the above embodiments, see Figure 2 , Figure 3 and Figure 7 The linear guide rail 3 has a groove along its length on the side away from the balcony railing 1. The linear guide rail 3 has symmetrical locking holes 6 that connect to the groove. The upper sliding module 2 includes an upper housing 201 with a through hole so that the upper housing 201 can be fitted onto the outside of the linear guide rail 3, specifically with an interference fit. The upper housing 201 is equipped with a first motor 202 and an upper transmission track 203. One end of the upper transmission track 203 is fixedly connected to the upper outer side of the linear guide rail 3, and the other end is fixedly connected to the bottom outer side of the upper housing 201. The shaft of the first motor 202 is equipped with an upper gear that meshes with the upper transmission track 203. The first motor 202 is used to control the up and down movement of the upper housing 201.

[0044] In other words, when the first motor 202 is working, the motor shaft drives the upper gear to rotate. The meshing of the gear with the upper transmission track 203 generates driving force. Since the two ends of the track are fixed, the reaction force pushes the upper housing 201 to move up and down along the guide rail. Furthermore, the upper housing 201 and the linear guide rail 3 adopt an interference fit, which can effectively eliminate radial clearance and improve the resistance to lateral forces. This makes it suitable for windy environments or heavy-duty guardrail applications. A graphite-based self-lubricating coating is added to the mating surfaces to reduce the coefficient of friction to 0.05~0.1.

[0045] Based on the above embodiments, the upper sliding module 2 also includes a first electromagnetic latch 204, which is used to cooperate with the locking hole 6 to lock the upper housing 201. A first bracket 205 is provided on the outer side of the upper housing 201, and the first bracket 205 is rotatably connected to the first connecting rod through a first rotating shaft.

[0046] In other words, the upper housing 201 is mechanically locked by the electromagnetic force driving the locking tongue to cooperate with the locking hole 6, preventing it from moving in an unexpected state. When the upper housing 201 slides to the target position, the first electromagnetic latch 204 is activated to ensure structural stability. The first electromagnetic latch 204 is a direct application of existing mature technology, therefore, this application will not elaborate on the specific structure.

[0047] See Figure 4 , Figure 5 and Figure 8 Based on the above embodiments, the lower sliding module 7 includes a lower housing 701, which is embedded in the groove of the linear guide rail 3 and can be an interference fit. The lower housing 701 is provided with a second motor 702 and a lower transmission track 703. One end of the lower transmission track 703 is fixedly connected to the upper inner side of the linear guide rail 3, and the other end is fixedly connected to the bottom outer side of the lower housing 701. The shaft of the second motor 702 is provided with a lower gear that meshes with the lower transmission track 703. The second motor 702 is used to control the up and down movement of the lower housing 701.

[0048] Specifically, the lower housing 701 is embedded in the groove of the linear guide rail 3 to ensure a stable connection between the module and the guide rail. The second motor 702 is located inside the lower housing 701 to provide a power source for the module. The motor shaft is equipped with a lower gear that meshes with the lower transmission track 703. Power is transmitted through gear transmission to control the lower housing 701 to move up and down along the linear guide rail 3, thereby realizing the vertical displacement adjustment of the module.

[0049] One end of the lower drive track 703 is fixedly connected to the upper inner side of the linear guide rail 3, and the other end is fixedly connected to the bottom outer side of the lower housing 701, forming a closed-loop transmission system. Driven by the second motor 702, the lower housing 701 moves stably along the guide rail through the meshing action of the gear and the track.

[0050] Working principle:

[0051] When the second motor 702 starts, the lower gear on its shaft begins to rotate. Through its meshing with the lower transmission track 703, the rotational motion is converted into linear motion, thereby driving the lower housing 701 to slide up and down along the linear guide rail 3.

[0052] Based on the above embodiments, the sliding module 7 further includes a second electromagnetic latch 704, which is used to cooperate with the locking hole 6 to lock the lower housing 701. A second bracket 705 is provided on the outer side of the lower housing 701, and the second bracket 705 is rotatably connected to the telescopic bracket 9 through a third rotating shaft.

[0053] The second electromagnetic latch 704 is integrated inside the lower sliding module 7. Its specific position can be set according to the actual layout requirements to ensure effective cooperation with the locking hole 6. The second electromagnetic latch 704 is designed to cooperate with the locking hole 6 on the external structure and lock the lower housing 701 at a specific position through electromagnetic force to prevent the module from sliding accidentally when it does not need to move, thereby improving the safety and stability of the system.

[0054] The second bracket 705 is fixedly installed on the outside of the lower housing 701 and is rotatably connected to the telescopic bracket 9 through the third rotating shaft. The design allows the telescopic bracket 9 to rotate at a certain angle relative to the lower sliding module 7 to adapt to the angle adjustment requirements under different working scenarios.

[0055] Based on the above embodiments, both the first motor 202 and the second motor 702 are servo motors.

[0056] Based on the above embodiments, see Figure 6 The telescopic support 9 includes a fixed rod and a sliding rod. The fixed rod is sleeved on the outside of the sliding rod. In other words, the telescopic support 9 is a direct use of existing mature technology. Therefore, the specific structure of the telescopic support 9 will not be described in detail here.

[0057] Based on the above embodiment, limit blocks are provided at both the upper and lower ends of the linear guide rail 3.

[0058] To prevent mechanical derailment, when the upper sliding module 2 and the lower sliding module 7 move along the linear guide rail 3 under the drive of the motor, once they approach the end of the linear guide rail 3, the limiting block will act as a physical barrier. For example, during the angle adjustment of the photovoltaic module 5, if the sliding module moves abnormally due to a control system failure or external interference, the limiting block can effectively prevent it from continuing to move towards the end, thus preventing the sliding module from falling off the linear guide rail 3 and preventing safety accidents.

[0059] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0060] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
