Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic power generation, and in particular to a wind and vibration suppression device during the installation of a photovoltaic power station. Background Art

[0002] Photovoltaic power station, also known as solar power station, is a power generation facility that uses solar panels to directly convert solar radiation into electrical energy. This type of power station is mainly composed of several key components: first, the photovoltaic panel, as the core of the power station, is responsible for converting sunlight into electrical energy; second, the bracket system, which not only fixes the photovoltaic panel, but also ensures that the panel can capture sunlight at the most ideal angle; then the inverter, which converts the direct current (DC) generated by the panel into alternating current (AC) for use in the home or grid; in addition, it also includes distribution equipment such as cables and circuit breakers, which are responsible for connecting and protecting the various components of the power station; and finally, the monitoring system, which is used to monitor the operating status of the power station in real time to ensure its stable operation. Among these components, the photovoltaic bracket is particularly critical because its stability is directly related to the performance of the entire photovoltaic power generation system. Wind and vibration are factors that may affect the stability of the photovoltaic bracket. Therefore, the use of wind and vibration suppression devices is crucial to improving the overall stability of the system.

[0003] In the current technical field, the control of wind and vibration of photovoltaic brackets usually relies on the method of strengthening the overall structure. Although this method can improve the stability of the structure, it also has certain limitations. Traditional methods of strengthening the structure mainly focus on improving the wind resistance of photovoltaic brackets, but ignore the potential utilization value of wind power as a renewable energy source. This approach fails to convert wind power into additional energy output, but may lead to a waste of wind resources. In addition, although strengthening the structure can enhance the stability of photovoltaic brackets in the short term, after long-term operation, the overall stability of the structure may still be reduced due to various factors such as material fatigue and environmental erosion. Summary of the invention

[0004] 1. Technical issues to be resolved

[0008] A power mechanism is fixedly arranged on one side of the wind power shaft body, a driven mechanism is rotatably arranged on the connecting sleeve near one side of the power mechanism, and a suppression mechanism is arranged inside the supporting connection mechanism near the lower end of the connecting sleeve;

[0009] The suppression mechanism includes a power output shaft and multiple driven gears. The lower end of the power output shaft is connected to the input shaft of the standby generator inside the wind turbine. A second bevel gear ring is fixedly provided on the upper end of the power output shaft. A lower connecting gear is fixedly sleeved near the middle position of the power output shaft. Multiple gravity rollers are fixedly provided on the lower ends of the multiple driven gears. The multiple gravity rollers are perpendicular to the ground on which the photovoltaic bracket is installed.

[0010] Preferably, the plurality of driven gears are rotatably disposed at the bottom of the supporting connection mechanism, and the plurality of driven gears are meshingly connected with the lower connecting gear.

[0011] Preferably, the power mechanism comprises a power turntable, a connecting column is fixedly provided at a middle position inside the power turntable, the connecting column is fixedly sleeved on the shaft body of the wind power shaft, and a plurality of supporting sliding rods are fixedly provided outside the connecting column.

[0012] Preferably, a plurality of the supporting slide rods are slidably provided with gravity hammers, and a return spring is fixedly connected between the plurality of gravity hammers and the connecting column.

[0013] Preferably, telescopic cylinders are fixedly provided at opposite ends of the plurality of gravity hammers, transmission pipes are penetrated through one side of the plurality of telescopic cylinders, and buffer racks are fixedly provided inside the power turntable near the positions of the plurality of telescopic cylinders.

[0014] Preferably, a telescopic disc is fixedly provided on one side of the power turntable away from the multiple telescopic cylinders, the other ends of the multiple transmission pipes are fixedly connected to the inside of the telescopic disc, and a power rotating gear is fixedly provided on one side of the telescopic disc.

[0015] Preferably, the driven mechanism includes a driven disk, a driven rotating tooth is fixedly provided on one side of the driven disk close to the power mechanism, a first bevel gear ring is fixedly provided on the other side of the driven disk, the first bevel gear ring is meshingly connected with the second bevel gear ring, and drives a connecting sleeve to rotate inside the driven disk.

[0016] Working principle: This device is arranged inside the photovoltaic bracket. First, a wind turbine is installed on the photovoltaic bracket. Electricity generated by wind power can be cooperated with photovoltaic power generation to achieve higher resource utilization. During the normal operation of the photovoltaic bracket and the wind turbine, the external wind force will blow the blades of the wind turbine to rotate, thereby driving the wind shaft to rotate. When the wind force is too strong, the wind shaft will drive the connecting column to rotate rapidly, thereby causing the supporting slide bar and the gravity hammer on the connecting column to rotate rapidly. When the centrifugal force received by the gravity hammer during rapid rotation is greater than the pulling force of the supporting spring, the gravity hammer will move to one side, thereby causing the telescopic cylinder to be squeezed and contracted. When the telescopic cylinder is compressed, the hydraulic oil inside it will be transmitted to the inside of the telescopic disk through the transmission pipe, thereby causing the telescopic disk to extend. At this time, the power gear on the telescopic disk will approach the driven gear and produce friction with it, thereby bringing The driven gear starts to rotate. When the driven gear rotates, the first bevel gear ring will also be driven to rotate, and then the second bevel gear ring will be driven to rotate. When the second bevel gear ring rotates, it will drive the power output shaft below to rotate. The power output shaft is connected to the backup generator, so that it can absorb the larger wind force and convert it into electrical energy. In the process of driving the backup generator to rotate, the lower connecting gear on the power output shaft will also drive multiple driven gears to rotate, and then drive multiple gravity rollers to rotate. Since the gravity roller has a large gravity and a long length, centrifugal force will be generated when the gravity roller rotates. This centrifugal force can offset or balance the impact of external loads on the photovoltaic bracket to a certain extent. At the same time, the rotating part of the gravity roller will interact with the internal structure of the photovoltaic bracket during the vibration process. This interaction can dissipate vibration energy, avoid the resonance peak of the vibration source, and reduce the vibration amplitude.

[0017] (III) Beneficial effects

[0018] The present invention provides a wind and vibration suppression device for use in the installation process of a photovoltaic power station. It has the following beneficial effects: The present invention relates to a wind and vibration suppression device for use in the installation process of a photovoltaic power station. The device is designed to be connected to the inside of a photovoltaic bracket, and can absorb wind force when the photovoltaic bracket is subjected to strong winds, and convert it into electrical energy. This process not only achieves efficient utilization of natural resources, but also when driving the standby generator to rotate, the lower connecting gear on the power output shaft will drive multiple driven gears to rotate, thereby causing multiple gravity rollers to rotate. Since the gravity rollers have a large mass and a long length, the centrifugal force they generate when rotating can offset or balance the impact of external loads on the photovoltaic bracket to a certain extent. In addition, the interaction between the rotating part of the gravity roller and the internal structure of the photovoltaic bracket during the vibration process can dissipate vibration energy, avoid the appearance of resonance peaks, thereby reducing the vibration amplitude and significantly improving the overall stability.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0026] like Figure 1-2 As shown, an embodiment of the present invention provides a wind and vibration suppression device during the installation of a photovoltaic power station, including a photovoltaic bracket, a wind turbine, a wind shaft 4, a connecting sleeve 3 and a supporting connection mechanism 6, the wind turbine is fixedly connected to the photovoltaic bracket, the wind shaft 4 is fixedly connected between the blades of the wind turbine and the input shaft of the generator, the supporting connection mechanism 6 is fixedly arranged inside the wind turbine near the lower side of the wind shaft 4, the connecting sleeve 3 is fixedly arranged inside the wind turbine near one end of the wind shaft 4, a power mechanism 1 is fixedly arranged on one side of the wind shaft 4, a driven mechanism 2 is rotatably arranged on the connecting sleeve 3 near one side of the power mechanism 1, and a suppression mechanism 5 is arranged inside the supporting connection mechanism 6 near the lower end of the connecting sleeve 3;

[0027] Specifically, in the above-mentioned specific embodiments, the device can be integrated into the internal structure of the photovoltaic bracket to maximize the use of renewable energy. First, a wind turbine is configured at a suitable position of the photovoltaic bracket to realize the conversion of wind energy into electrical energy. Through this strategy, wind power generation and photovoltaic power generation can achieve synergy and significantly improve the comprehensive utilization rate of resources. During the normal operation of the photovoltaic bracket and the wind turbine, the external wind force acts on the blades of the wind turbine to cause them to rotate. The rotation of the blades drives the wind shaft 4 to rotate, thereby completing the power generation process. In order to ensure the stability and safety of the system, when the wind is strong, a special suppression mechanism 5 is used to enhance the stability of the device to avoid damage or failure of the equipment due to excessive wind. This design not only improves the efficiency of energy utilization, but also ensures the stable operation of the equipment under changing climate conditions.

[0028] like Figure 3-5As shown, the power mechanism 1 includes a power turntable 102, a connecting column 110 is fixedly provided at the middle position inside the power turntable 102, the connecting column 110 is fixedly sleeved on the shaft body of the wind shaft 4, a plurality of supporting slide bars 108 are fixedly provided outside the connecting column 110, gravity hammers 107 are slidably provided on the shaft bodies of the plurality of supporting slide bars 108, a return spring 109 is fixedly connected between the plurality of gravity hammers 107 and the connecting column 110, telescopic cylinders 106 are fixedly provided on the opposite ends between the plurality of gravity hammers 107, a transmission pipe 101 is penetrated on one side of the plurality of telescopic cylinders 106, a buffer frame 105 is fixedly provided at the position of the plurality of telescopic cylinders 106 inside the power turntable 102, a telescopic disk 103 is fixedly provided on the side of the power turntable 102 away from the plurality of telescopic cylinders 106, the other ends of the plurality of transmission pipes 101 are fixedly connected to the inside of the telescopic disk 103, and a power rotating gear 104 is fixedly provided on one side of the telescopic disk 103;

[0029] Specifically, in the above-mentioned specific embodiment, during the normal operation of the photovoltaic support and the wind turbine, the external wind force acts on the blades of the wind turbine, causing them to rotate. The rotation of the blades drives the rotation of the wind shaft. When the wind force reaches a certain intensity, the wind shaft drives the connecting column 110 to rotate at high speed. The support slide bar 108 and the counterweight hammer on the connecting column 110 also rotate at high speed. When the centrifugal force on the counterweight hammer in the high-speed rotation state exceeds the tension of the support spring, the counterweight hammer will deviate to one side. This deviation causes the telescopic cylinder 106 to be compressed and then contracted. When the telescopic cylinder 106 is compressed, the hydraulic oil inside it is transferred to the inside of the telescopic disk 103 through the oil pipe. The transfer of hydraulic oil allows the telescopic disk 103 to extend. At this time, the power teeth and the driven teeth on the telescopic disk 103 are close to each other.

[0030] like Figure 2-5 As shown, the driven mechanism 2 includes a driven disc 201, a driven rotating gear 203 is fixedly arranged on one side of the driven disc 201 close to the power mechanism 1, and a first bevel gear ring 202 is fixedly arranged on the other side of the driven disc 201. The first bevel gear ring 202 is meshed and connected with the second bevel gear ring 501, driving the connecting sleeve 3 to rotate inside the driven disc 201;

[0031] Specifically, in the above-mentioned specific embodiment, when the power rotating gear 104 of the telescopic disk 103 gradually approaches and begins to generate frictional contact with the driven rotating gear 203, the friction force will drive the driven rotating gear 203 to start rotating. As the driven rotating gear 203 rotates, the first bevel gear ring 202 fixed thereto will also rotate accordingly. The rotation of the first bevel gear ring 202 further prompts the second bevel gear ring 501 meshing therewith to start rotating. When the second bevel gear ring 501 starts to rotate, it will transmit power to the power output shaft 504 below through a mechanical transmission mechanism. The power output shaft 504 is closely connected to the standby generator, so that the absorbed wind energy can be converted into electrical energy through the operation of the generator. Through this mechanism, the natural resource of wind energy is further utilized and converted into usable electrical energy, thereby achieving efficient utilization and sustainable development of natural resources.

[0032] like Figure 2 As shown, the suppression mechanism 5 includes a power output shaft 504 and a plurality of driven gears 503. The lower end of the power output shaft 504 is connected to the input shaft of the standby generator inside the wind turbine. The upper end of the power output shaft 504 is fixedly provided with a second bevel gear ring 501. The power output shaft 504 is fixedly sleeved with a lower connecting gear 502 near the middle position. The lower ends of the plurality of driven gears 503 are all fixedly provided with a plurality of gravity rollers 505. The plurality of gravity rollers 505 are perpendicular to the ground on which the photovoltaic bracket is installed. The plurality of driven gears 503 are all rotatably provided at the bottom of the support connection mechanism 6. The plurality of driven gears 503 are all meshed and connected with the lower connecting gear 502.

[0033] Specifically, in the above-mentioned specific embodiment, during the process of starting the standby generator, the lower connecting gear 502 on the power output shaft 504 will synchronously drive the multiple driven gears 503 to rotate. The rotation of these driven gears 503 further prompts the multiple gravity rollers 505 to start rotating. In view of the large mass and long length of these gravity rollers 505, significant centrifugal force will be generated during their rotation. This centrifugal force can effectively counteract or balance the impact of external loads on the photovoltaic bracket to a certain extent. At the same time, during the rotation of the gravity roller 505, its rotating parts interact with the internal structure of the photovoltaic bracket. This interaction can effectively dissipate vibration energy, so that the photovoltaic bracket avoids the resonance peak of the vibration source and significantly reduces the vibration amplitude.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
