Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment technology, and in particular to a solar photovoltaic module. Background Technology

[0002] In order to ensure that the photovoltaic panel remains tilted toward the sun, the photovoltaic panel needs to be installed on a photovoltaic bracket. Since there are many specifications of photovoltaic panels and many types of fasteners used, the photovoltaic bracket needs to be screened according to the specifications of the photovoltaic panel, which makes the photovoltaic bracket less versatile and cannot be compatible with a variety of photovoltaic panels. In addition, the environment where the photovoltaic panel is located is relatively wide and the environmental factors are relatively complex, which causes a large amount of debris to adhere to the light-receiving surface of the photovoltaic panel, causing shading problems and affecting the light-receiving efficiency of the photovoltaic panel. In this regard, this application document proposes a solar photovoltaic component to solve the above-mentioned problems. SUMMARY OF THE INVENTION

[0003] This application proposes a solar photovoltaic module, which has the advantages of better adaptability and more convenient installation, and is used to solve the problem that traditional photovoltaic modules need to be designed separately according to the specifications of photovoltaic panels.

[0004] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a solar photovoltaic assembly, comprising an upper main beam and a lower main beam, an upper side beam is fixedly installed on the front side of the upper main beam near the two ends, an upper connecting rod is fixedly installed on the inner side of the upper side beam, an upper motor is arranged at both ends of the upper main beam, an upper spring connecting rod is fixedly installed on one end of the output shaft of the upper motor, a supporting device is arranged at the bottom of the upper side beam near the two ends, a lower side beam is fixedly installed on the back side of the lower main beam near the two ends, a lower connecting rod is fixedly installed on the inner side of the lower side beam, a photovoltaic power generation device is movably sleeved on the outer surfaces of the upper connecting rod and the lower connecting rod, a lower motor is arranged at both ends of the lower main beam, a lower spring connecting rod is fixedly installed on one end of the output shaft of the lower motor, one end of the upper spring connecting rod is connected to the lower side beam, and one end of the lower spring connecting rod is connected to the upper side beam.

[0005] Furthermore, the upper connecting rods and the lower connecting rods are distributed in a linear array, and the bottom surface of the upper beam is in contact with the top surface of the lower beam in the initial state.

[0006] Furthermore, the photovoltaic power generation device includes a photovoltaic power generation panel, a short-legged semicircular buckle is arranged at the bottom of the photovoltaic power generation panel near the front end, and the short-legged semicircular buckle is sleeved with the upper connecting rod, and a long-legged semicircular buckle is arranged at the bottom of the photovoltaic power generation panel near the end, and the long-legged semicircular buckle is sleeved with the lower connecting rod.

[0007] Furthermore, the support device includes a bottom plate, a pressure sensor is arranged at the top of the bottom plate near the four corners, a spring matching rod is arranged at the top of the pressure sensor, a travel plate is movably installed above the pressure sensor through the connection of the spring matching rod, an air slot is arranged at the top of the travel plate, a stopper is arranged at the top of the travel plate above the air slot, an air pump is fixedly installed on the top of the bottom plate, the output end of the air pump is connected to the spring matching rod through multiple sets of pipes, and a rotating base is arranged at the bottom of the bottom plate.

[0008] Furthermore, the pressure sensor calculates the elastic potential energy stored in the spring matching rod and transmits the elastic potential energy data to the air pump through the output end.

[0009] Furthermore, the output torque of the upper motor and the lower motor will respectively drive the upper spring connecting rod and the lower spring connecting rod to rotate, driving the upper side beam and the lower side beam to separate. During this process, the photovoltaic power generation device rotates with the axis of the upper connecting rod as the rotation center until the photovoltaic power generation device contacts the block and stops rotating. At this time, the wind trough and the light-receiving surface of the photovoltaic power generation device remain corresponding, and the photovoltaic power generation device is now in a mutually perpendicular state with the upper side beam.

[0010] This application has the following beneficial effects.

[0011] The upper connecting rod and the lower connecting rod used to connect the photovoltaic power generation device can be freely adjusted according to the spacing between the short-leg semicircular buckle and the long-leg semicircular buckle. After the first photovoltaic power generation device is completed, the upper connecting rod and the lower connecting rod are adjusted to facilitate the installation of subsequent photovoltaic power generation devices, and at the same time, the adaptability of the device to photovoltaic power generation devices of different specifications is improved. In addition, the upper motor and the lower motor can drive the upper spring connecting rod and the lower spring connecting rod respectively, so that the upper side beam and the lower side beam are separated up and down, so that the photovoltaic power generation device is in a vertical state. At this time, the debris and dust attached to the light-receiving surface of the photovoltaic power generation device can slide down under the action of gravity, which plays a cleaning role. At the same time, the airflow generated by the wind trough can also clean the light-receiving surface of the photovoltaic power generation device, and the airflow intensity provided by the wind trough can be automatically adjusted according to the size of the photovoltaic power generation device.

Specific implementation method

[0015] The following will combine the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0016] A solar photovoltaic module, see Figure 1-Figure 3 , comprising an upper main beam 1 and a lower main beam 2, an upper side beam 3 is fixedly installed on the front of the upper main beam 1 near both ends, an upper connecting rod 4 is fixedly installed on the inner side of the upper side beam 3, an upper motor 5 is arranged at both ends of the upper main beam 1, an upper spring connecting rod 6 is fixedly installed on one end of the output shaft of the upper motor 5, a supporting device 7 is arranged at the bottom of the upper side beam 3 near both ends, a lower side beam 8 is fixedly installed on the back of the lower main beam 2 near both ends, a lower connecting rod 9 is fixedly installed on the inner side of the lower side beam 8, a photovoltaic power generation device 10 is movably sleeved on the outer surfaces of the upper connecting rod 4 and the lower connecting rod 9, a lower motor 11 is arranged at both ends of the lower main beam 2, a lower spring connecting rod 12 is fixedly installed on one end of the output shaft of the lower motor 11, one end of the upper spring connecting rod 6 is connected to the lower side beam 8, and one end of the lower spring connecting rod 12 is connected to the upper side beam 3.

[0017] Please refer to Figure 1-Figure 3 , the upper connecting rod 4 and the lower connecting rod 9 are distributed in a linear array, and the bottom surface of the upper beam 3 is in contact with the top surface of the lower beam 8 in the initial state.

[0018] Please refer to Figure 3-Figure 4 ​The photovoltaic power generation device 10 includes a photovoltaic power generation panel 101. A short-legged semicircular buckle 102 is arranged at the bottom of the photovoltaic power generation panel 101 near the front end. The short-legged semicircular buckle 102 is sleeved with the upper connecting rod 4. A long-legged semicircular buckle 103 is arranged at the bottom of the photovoltaic power generation panel 101 near the end. The long-legged semicircular buckle 103 is sleeved with the lower connecting rod 9.

[0019] When installing the photovoltaic power generation device 10, the short-legged semicircular buckle 102 is clamped with the upper connecting rod 4, and the long-legged semicircular buckle 103 is clamped with the lower connecting rod 9, so as to complete the fixation of the photovoltaic power generation device 10. When installing the photovoltaic power generation device 10, the lower side beam 8 and the upper side beam 3 are relatively displaced, thereby driving the upper spring connecting rod 6 to stretch and store elastic potential energy. The elastic force stored in the upper spring connecting rod 6 acts on the short-legged semicircular buckle 102 and the long-legged semicircular buckle 103 through the upper connecting rod 4 and the lower connecting rod 9, thereby locking the photovoltaic power generation device 10, ensuring that the photovoltaic power generation device 10 remains stable after installation, and there will be no problem of loose connection, and the difficulty of installing the photovoltaic power generation device 10 is reduced, thereby improving the practicality of the device.

[0020] When installing the photovoltaic power generation device 10, the upper side beam 3 and the lower side beam 8 are relatively displaced, and the displacement distance is equal to the distance between the short-leg semicircular buckle 102 and the long-leg semicircular buckle 103. This makes the distance between the upper connecting rod 4 and the lower connecting rod 9 equal to the distance between the short-leg semicircular buckle 102 and the long-leg semicircular buckle 103 after the upper side beam 3 and the lower side beam 8 are displaced, so that the upper connecting rod 4 and the lower connecting rod 9 automatically complete the adaptation of the photovoltaic power generation device 10, which improves the convenience of installation of the device. At the same time, the distance between the upper connecting rod 4 and the lower connecting rod 9 in the device can be freely adjusted, so that it can adapt to photovoltaic power generation devices 10 of any size, providing the adaptability of the device.

[0021] Since the structure for fixing the photovoltaic power generation device 10 adopts a split design, specifically the upper main beam 1, the upper side beam 3 and the upper connecting rod 4 and the lower main beam 2, the lower side beam 8 and the lower connecting rod 9, when the upper motor 5 and the lower motor 11 simultaneously drive the upper spring connecting rod 6 and the lower spring connecting rod 12 to rotate, the upper side beam 3 and the lower side beam 8 are in a separated device after rotation, and the light-receiving surface of the photovoltaic power generation panel 101 is in a vertical state with the extension direction of the upper side beam 3 (specifically as Figure 7 shown), this allows the sundries and dust attached to the light-receiving surface of the photovoltaic panel 101 to slide directly under the action of gravity, thereby achieving the effect of preliminary cleaning of the light-receiving surface of the photovoltaic panel 101, avoiding the problem of reduced photovoltaic power generation efficiency due to excessive sundries and dust attached to the surface of the photovoltaic panel 101, and improving the practicality of the device.

[0022] Please refer to Figure 5-Figure 6The supporting device 7 includes a bottom plate 71, a pressure sensor 72 is arranged at the top of the bottom plate 71 near the four corners, a spring matching rod 73 is arranged at the top of the pressure sensor 72, a travel plate 74 is movably installed above the pressure sensor 72 through the connection of the spring matching rod 73, a wind slot 75 is arranged at the top of the travel plate 74, a stopper 76 is arranged at the top of the travel plate 74 above the wind slot 75, an air pump 77 is fixedly installed on the top of the bottom plate 71, and the output end of the air pump 77 is connected to the spring matching rod 73 through multiple sets of pipes, and a rotating base 78 is arranged at the bottom of the bottom plate 71.

[0023] When the upper motor 5 and the lower motor 11 simultaneously drive the upper spring connecting rod 6 and the lower spring connecting rod 12 to rotate, the photovoltaic power generation device 10 can rotate with the center line of the upper connecting rod 4 as the rotation center until the back of the photovoltaic power generation panel 101 contacts the block 76 and stops, and while the photovoltaic power generation device 10 rotates, it pushes the stroke plate 74 to move toward the bottom plate 71. At this time, the pressure sensor 72 senses the elastic force generated by the compression of the spring matching rod 73, and is connected to the air pump 77 through the output end of the spring matching rod 73 by a signal connection, thereby activating the air pump 77 and running it, and conducting the airflow to the wind slot 75 through the pipeline. Since the photovoltaic power generation device 10 contacts the block 76 and stops rotating, the wind slot 75 corresponds to the light-receiving surface of the photovoltaic power generation device 10, so that the airflow can act on the light-receiving surface of the photovoltaic power generation device 10, thereby achieving a cleaning effect on the light-receiving surface of the photovoltaic power generation device 10, and the device uses multiple groups of wind slots 75 to clean the photovoltaic power generation device 10 at the same time, reducing the stroke of the airflow on the surface of the photovoltaic power generation device 10, thereby increasing the flow rate of the airflow on the surface of the photovoltaic power generation device 10 and ensuring the cleaning effect. In traditional equipment, the generated airflow needs to pass through multiple photovoltaic power generation devices 10, resulting in a longer stroke of the airflow, so that the flow rate of the airflow is continuously weakened during the flow process, resulting in a reduction in the cleaning effect of the photovoltaic power generation device 10 at the end. The present application document avoids this problem very well and improves the practicality of the device.

[0024] Please refer to Figure 5-Figure 6 The pressure sensor 72 calculates the elastic potential energy stored in the spring-cooperating rod 73 and transmits the elastic potential energy data to the air pump 77 through the output end.

[0025] Please refer to Figure 3 and Figure 6 ​​The output torque of the upper motor 5 and the lower motor 11 will respectively drive the upper spring connecting rod 6 and the lower spring connecting rod 12 to rotate, driving the upper side beam 3 and the lower side beam 8 to separate. During this process, the photovoltaic power generation device 10 rotates with the axis of the upper connecting rod 4 as the rotation center until the photovoltaic power generation device 10 contacts the block 76 and stops rotating. At this time, the wind groove 75 keeps corresponding to the light-receiving surface of the photovoltaic power generation device 10, and the photovoltaic power generation device 10 is in a mutually perpendicular state with the upper side beam 3.

[0026] When the length of the photovoltaic power generation device 10 is larger, the interval between the upper connecting rod 4 and the lower connecting rod 9 increases after installation. After the photovoltaic power generation device 10 rotates, the displacement distance of the travel plate 74 increases, and the compression rate of the spring matching rod 73 increases, so that the pressure received by the pressure sensor 72 increases. Since the pressure sensor 72 calculates the elastic potential energy stored in the spring matching rod 73 and transmits the elastic potential energy data to the air pump 77 through the output end, the operating power of the air pump 77 is increased, and the wind speed output by the wind slot 75 is increased. Similarly, when the length of the photovoltaic power generation device 10 is smaller, the operating power of the air pump 77 is reduced, and the wind speed output by the wind slot 75 is reduced, so that the wind speed output by the wind slot 75 can be automatically adjusted according to the length of the photovoltaic power generation device 10, ensuring that the air pump 77 is at the best operating power. Under the premise of ensuring the cleaning effect of the device on the photovoltaic power generation device 10, the energy consumption of the device is reduced.

[0027] The method of using the present invention is as follows: During use, the short-legged semicircular buckle 102 and the long-legged semicircular buckle 103 are respectively installed at the bottom of the photovoltaic panel 101 near the front end and the end. When installing the first photovoltaic power generation device 10, the bottom semicircular buckle of the long-legged semicircular buckle 103 is first connected to the lower connecting rod 9, and the bottom semicircular buckle of the short-legged semicircular buckle 102 is connected to the upper connecting rod 4. During the installation of the short-legged semicircular buckle 102, the long-legged semicircular buckle 103 pushes the lower connecting rod 9 thus drives the lower side beam 8 and the upper side beam 3 to move relative to each other, so that the spacing between the lower connecting rod 9 and the upper connecting rod 4 is the same as the spacing between the short-leg semicircular buckle 102 and the long-leg semicircular buckle 103. After the installation of the first photovoltaic power generation device 10 is completed, the upper spring connecting rod 6 stretches and stores elastic potential energy. The elastic force stored in the upper spring connecting rod 6 acts on the short-leg semicircular buckle 102 and the long-leg semicircular buckle 103 through the upper connecting rod 4 and the lower connecting rod 9, thereby locking the photovoltaic power generation device 10 to ensure photovoltaic power generation. The device 10 remains stable after installation, and there will be no problem of loose connection. When the photovoltaic power generation device 10 is installed, the upper side beam 3 and the lower side beam 8 are relatively displaced, which makes the upper connecting rod 4 and the lower connecting rod 9 automatically complete the adaptation of the photovoltaic power generation device 10 during the subsequent installation of the photovoltaic power generation device 10, thereby improving the convenience of installation of the device. At the same time, the spacing between the upper connecting rod 4 and the lower connecting rod 9 in the device can be freely adjusted, so that it can adapt to photovoltaic power generation devices 10 of any size. Since the structure for fixing the photovoltaic power generation device 10 adopts a split design, specifically the upper main beam 1, the upper side beam 3 and the upper connecting rod 4 and the lower main beam 2, the lower side beam 8 and the lower connecting rod 9, when the upper motor 5 and the lower motor 11 simultaneously drive the upper spring connecting rod 6 and the lower spring connecting rod 12 to rotate, the upper side beam 3 and the lower side beam 8 are in a separated device after rotation, and the light-receiving surface of the photovoltaic power generation panel 101 is perpendicular to the extension direction of the upper side beam 3 (specifically as Figure 7As shown), this allows the debris and dust attached to the light-receiving surface of the photovoltaic panel 101 to slide directly under the action of gravity, thereby achieving the effect of preliminary cleaning of the light-receiving surface of the photovoltaic panel 101. When the upper motor 5 and the lower motor 11 simultaneously drive the upper spring connecting rod 6 and the lower spring connecting rod 12 to rotate, the photovoltaic power generation device 10 can rotate with the center line of the upper connecting rod 4 as the rotation center until the back of the photovoltaic panel 101 contacts the block 76 and achieves a stop effect, and while the photovoltaic power generation device 10 rotates, it will push the travel plate 74 to approach the bottom plate The pressure sensor 72 senses the elastic force generated by the compression of the spring matching rod 73, and is connected to the air pump 77 through the output end of the spring matching rod 73 by a signal connection, thereby activating the air pump 77 and running it, and transmitting the airflow to the air slot 75 through the pipeline. Since the photovoltaic power generation device 10 contacts the stopper 76 and stops rotating, the air slot 75 and the light-receiving surface of the photovoltaic power generation device 10 keep corresponding, so that the airflow can act on the light-receiving surface of the photovoltaic power generation device 10, thereby achieving the cleaning of the light-receiving surface of the photovoltaic power generation device 10. The device adopts multiple groups of wind slots 75 to clean the photovoltaic power generation device 10 at the same time, reducing the stroke of the airflow on the surface of the photovoltaic power generation device 10, thereby increasing the flow rate of the airflow on the surface of the photovoltaic power generation device 10 and ensuring the cleaning effect. When the length of the photovoltaic power generation device 10 is larger, the interval between the upper connecting rod 4 and the lower connecting rod 9 increases after installation. After the photovoltaic power generation device 10 rotates, the displacement distance of the travel plate 74 increases, and the compression rate of the spring matching rod 73 increases, so that the pressure received by the pressure sensor 72 increases. 2 calculates the elastic potential energy stored in the spring matching rod 73, and transmits the elastic potential energy data to the air pump 77 through the output end, thereby increasing the operating power of the air pump 77 and increasing the wind speed output by the wind slot 75. Similarly, when the length of the photovoltaic power generation device 10 is smaller, the operating power of the air pump 77 is reduced, and the wind speed output by the wind slot 75 is reduced, so that the wind speed output by the wind slot 75 can be automatically adjusted according to the length of the photovoltaic power generation device 10, ensuring that the air pump 77 is at the best operating power, while ensuring the cleaning effect of the device on the photovoltaic power generation device 10.
