Description

Technical Field

[0002] The photovoltaic modules in the photovoltaic power generation equipment are installed on a fixed bracket, with the light-receiving surface facing the sun to receive sunlight energy, and then convert solar energy into electrical energy to generate electricity. The prior art generally uses a fixed bracket to install photovoltaic panels, and the photovoltaic modules are fixedly connected to the columns through the fixed bracket. The fixed installation method is suitable for relatively harsh environments such as the wild, mountainous and coastal beaches. However, when building photovoltaic power stations in the wild, mountainous and coastal beaches, photovoltaic power stations are usually faced with strong winds. When strong winds blow towards the photovoltaic panels, the photovoltaic panels will generate resistance, and this resistance will act on the fixed bracket on which the photovoltaic panels are installed. Since the fixed bracket is a rigid support, the fixed bracket is prone to vibration and deformation under the action of strong winds, and may even be blown over by strong winds.

[0003] Therefore, a photovoltaic power generation equipment installation base is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 , the utility model provides a technical solution:

[0020] A photovoltaic power generation equipment mounting base comprises a base 101, on which a rotating mechanism is arranged, the rotating mechanism is connected to at least one group of supporting mechanisms, the supporting mechanism is connected to a mounting plate 201 for mounting a photovoltaic panel, the supporting mechanism comprises a fixed arm 301, a movable arm 302, an elastic telescopic rod 303 and a flexible limiting mechanism, one end of the fixed arm 301 is connected to the rotating mechanism, and the other end is provided with a supporting column 304; one end of the movable arm 302 is hinged to the supporting column 304, and the other end is hinged to the mounting plate 201; both ends of the elastic telescopic rod 303 are respectively hinged to the movable arm 302 and the mounting plate 201, and the length of the elastic telescopic rod 303 is less than the length of the movable arm 302; the flexible limiting mechanism is arranged at one end of the movable arm 302 close to the supporting column 304, and cooperates with the supporting column 304 so that the angle between the movable arm 302 and the fixed arm 301 is an acute angle; when there is a strong wind, the rotating mechanism rotates so that the mounting surface of the mounting plate 201 is on the windward side.

[0021] In some implementations of the present embodiment, the flexible limiting mechanism includes a limiting column 305 fixedly connected to the movable support arm 302, a torsion spring 306 sleeved on the limiting column 305, and a dial plate 307 rotatably connected to the limiting column 305, one of the torsion arms of the torsion spring 306 abuts against the dial plate 307; the torsion spring 306 makes the limiting surface of the dial plate 307 abut against the support column 304; when the angle between the movable support arm 302 and the fixed support arm 301 is an acute angle, the rotatable direction of the dial plate 307 is opposite to the natural rotation direction of the movable support arm 302.

[0022] In some implementations of this embodiment, the rotating mechanism includes a control module, a motor 401, a driving gear 402, a driven gear 403 and a protective cover 404; a rotating shaft 405 is provided on the base 101, the protective cover 404 is rotatably connected to the rotating shaft 405, and the driven gear 403 is connected to the rotating shaft 405; the motor 401 is provided on the protective cover 404, the driving gear 402 is drivingly connected to the output shaft of the motor 401, and the driving gear 402 and the driven gear 403 are meshed with each other; the control module is electrically connected to the motor 401. In this embodiment, three sets of supporting mechanisms are installed on the protective cover 404, corresponding to three independent mounting plates 201.

[0023] In some implementations of this embodiment, the control module includes a controller (not shown in the figure), a wind speed and direction sensor (not shown in the figure) and a solar tracker (not shown in the figure), and the wind speed and direction sensor, the solar tracker, and the motor 401 are all electrically connected to the controller. The model of the wind speed and direction sensor used in this embodiment is FA21-3W50SW7, which is an industrial wind speed and direction sensor with strong environmental adaptability. The product has a built-in sensitive temperature sensor, which can automatically heat up in a low temperature environment to ensure the operation of the sensor. Its wind speed measurement range is 0-50m / s; its wind direction measurement range is 0-360°. The model of the solar tracker used in this embodiment is SOLYS2.

[0024] In some implementations of this embodiment, the protective cover 404 is further connected to a limit plate 501 with a U-shaped structure, which is used to limit the movable angle of the mounting plate 201. The purpose of installing the limit plate 501 is to prevent the mounting plate 201 from moving at too large an angle, thereby causing it to be turned up and unusable.

[0025] Working principle:

[0026] In calm or light wind weather, the rotating mechanism does not work. Figure 4 From the perspective of the movable arm 302, since the angle between the movable arm 302 and the fixed arm 301 is an acute angle, the movable arm 302 tends to rotate clockwise around the central axis of the support column 304. However, due to the presence of the torsion spring 306, the paddle 307 cannot rotate clockwise, but can only rotate counterclockwise until the paddle 307 abuts against the support column 304. When the movable arm 302 wants to rotate clockwise around the central axis of the support column 304, the presence of the torsion spring 306 causes the paddle 307 to prevent the movable arm 302 from rotating clockwise around the central axis of the support column 304. The sum of the deadweight of the photovoltaic panel, the mounting plate 201, the elastic telescopic rod 303 and the movable arm 302 counteracts the torsion of the torsion spring 306, so that this structure can be maintained. Figure 4 This state of equilibrium.

[0027] When encountering strong winds, the rotating mechanism works first, and its wind speed and direction sensor monitors the wind speed and direction, and then transmits this signal to the controller. The controller then controls the motor 401 to work, and the protective cover 404 rotates to change the windward direction of the mounting plate 201 (photovoltaic panel), so that the light-receiving surface of the photovoltaic panel is in the windward position. The wind acts on the photovoltaic panel, and then the elastic telescopic rod 303 is compressed under the pressure of the mounting plate 201 and the photovoltaic panel. The amplitude of the downward pressure is different due to different forces, so as to have a buffering effect. At the same time, the torsion spring 306 is also compressed in this process, and cooperates with the elastic telescopic rod 303 to play a buffering role. The pitch angle of the photovoltaic panel will change in this process. When the strong wind disappears, the support mechanism is in a balanced state again under the action of the torsion spring 306.

[0028] After the strong wind, the solar tracker finds the angle of the sun, and then transmits the signal value to the controller, which controls the motor 401 to work, so that the protective cover 404 rotates, and then the light-receiving surface of the photovoltaic panel is aligned with the sun to generate electricity. In this way, the support mechanism can be protected in windy weather, even if the power generation is lost for a period of time, it is worthwhile overall.

[0029] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
