Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

As an aspect of the present invention, there is provided a solar cell carrier assembly including a carrier 100, wherein the solar cell mounting assembly further includes an angle adjustment mechanism 200 and a control module 300, as shown in fig. 5. As shown in fig. 1, the carrier includes a first carrier 110, and the first carrier 110 includes a first carrier surface for carrying the solar cell, and an angle of the first carrier surface with respect to a horizontal plane is adjustable. The control module 300 is configured to receive the position information sent by the positioning device 400, where the position information includes the longitude and latitude where the solar cell carrier assembly is located. The control module 300 can calculate the sun position using the received position information and the current time and convert the sun position information into the first movement control signal of the angle adjustment mechanism 200. The control module 300 can send the first movement control signal to the angle adjusting mechanism 200, and the angle adjusting mechanism 200 can drive the bearing frame 100 to move after receiving the first movement control signal, so that the first bearing surface faces the sun.

In the present invention, the solar cell carrier assembly is used in conjunction with a positioning device (e.g., GPS). The control module 300 can easily calculate the current sun position according to the latitude and longitude provided by the solar cell provided by the positioning device 400 and the current time. Since the positioning device 400 does not need to be fixed on the carriage, the weight of the carriage can be reduced, and the angular adjustment mechanism 200 can drive the carriage to move with a smaller driving force. Therefore, the solar cell bearing assembly provided by the invention can quickly and accurately determine the position of the sun and control the first bearing surface to face the sun, so that the maximum power generation can be obtained.

Along with the change of time, the position of the sun also changes, the control module 300 can continuously calculate the position of the sun, and control the angle adjusting mechanism 200 to continuously adjust the orientation of the first bearing surface, so as to ensure that the first bearing surface is over against the sun in the whole day, and thus, larger power generation can be realized.

Because the solar cell bearing assembly provided by the invention can enable the solar cell to face the sun, the solar cell provided by the invention generates more electricity than the electricity generated by flatly laying the solar cell on the horizontal ground.

Preferably, the position information may further include information such as an altitude, a declination, and the like of a position where the solar cell carrier assembly is located.

No additional sun tracking mechanism is provided on the carrier 100, and therefore the carrier 100 has a light weight. The solar cell bearing assembly provided by the invention is particularly suitable for being matched with a vehicle. In this case, the carriage 100 and the angle adjustment mechanism 200 may be installed outside the vehicle, the control module 300 may be installed inside the vehicle, and a navigation system of the vehicle may be used as the positioning device 400 for providing the latitude and longitude where the solar cell module is located. The solar cells are disposed on the carrier 100.

In order to make the first bearing surface of the first bearing frame 110 face the sun precisely, preferably, the solar cell bearing assembly further comprises an electrical signal measuring module 500, and the electrical signal measuring module 500 is used for detecting an electrical signal generated by the solar cell carried by the first bearing surface and sending the value of the electrical signal to the control module 300. The control module 300 can control the angular adjustment mechanism 200 to stop driving when the value of the received electrical signal reaches a maximum.

In the invention, the orientation of the first bearing surface can be coarsely adjusted rapidly according to the positioning device 400 and the current time, and the orientation of the first bearing surface can be finely adjusted by using the electrical signal measurement module 500, so that the maximum solar power generation on the first bearing surface can be realized.

The solar cell bearing assembly provided by the invention has the advantages of small volume, light weight and convenience in carrying, so that the solar cell bearing assembly provided with the solar cell can be placed on the roof, the lake side, the side of a building and the like. In order to ensure the maximization of the power generation capacity, preferably, the electrical signal measuring module 500 is further configured to send a blocking signal to the control module 300 when the value of the electrical signal is smaller than a preset value after the first bearing surface faces the sun, and the control module 300 is configured to send a second movement control signal to the angle adjusting mechanism 200 after receiving the blocking signal, and the angle adjusting mechanism 200 is configured to drive the bearing frame to move after receiving the second movement control signal so as to change the orientation of the first bearing surface.

If the maximum electrical signal value detected by the electrical signal measuring module 500 is still smaller than the preset value, it indicates that the solar cell carrier assembly is blocked. In this case, the angular adjustment mechanism 200 can be used to drive the carriage 100 to move continuously to find the position capable of reflecting sunlight, and at this time, the electric signal measurement module 500 can continue to operate. When the electrical signal measuring module 500 detects that the value of the electrical signal reaches the maximum, the control module 300 controls the angle adjusting mechanism 200 to stop driving.

For example, as described above, a solar cell carrier module provided with solar cells may be placed beside a lake, a curtain wall of a building, or the like. The lake surface can reflect sunlight, and the curtain wall can also reflect sunlight. When the solar cell bearing assembly provided with the solar cell is placed beside a lake or a curtain wall of a building, and the sun is shielded, the power generation amount is reduced, and when the electric signal value detected by the electric signal measuring device 500 is smaller than a preset value, the control module 300 controls the angle adjusting handpiece 200 again to drive the first bearing frame to rotate so as to find sunlight reflected by light reflecting surfaces such as a lake surface and the curtain wall and further to find the maximization of the power generation amount.

In order to improve the power generation output, it is preferable that the carrier 100 further includes a plurality of second carriers 120, and the solar cell carrier assembly further includes second carrier driving mechanisms, each of which includes a second carrier surface for carrying a solar cell, as shown in fig. 3.

The second carrier driving mechanism may be configured to keep the second carrier overlapping the first carrier when the angle adjustment mechanism drives the first carrier to move, and the second carrier driving mechanism may drive the plurality of second carriers to be spread such that the second carrier surfaces are parallel or coplanar with the first carrier surfaces when the carrier surfaces of the first carriers are driven toward the sun.

The area of the second bearing surface can be the same as that of the first bearing surface or different from that of the first bearing surface.

As an embodiment, the area of the second carrying surface may be set to be the same as the area of the first carrying surface. Therefore, the solar cells with the same specification and size can be arranged on the first bearing surface and the second bearing surface, and when the solar cells are purchased, the solar cells of the same model can be purchased in batches. When one solar cell fails, the solar cell can be replaced by the same type, so that the maintenance cost can be reduced.

When the angle adjustment mechanism 200 drives the first bearing frame 110 to move, the second bearing frame overlaps the first bearing frame 110, so that the bearing frames have a small volume, and therefore, in the process of adjusting the angle of the first bearing frame 110, surrounding obstacles are not easily touched, and the first bearing surface can be adjusted to a position facing the sun. After the first support surface is adjusted to a position facing the sun, the second carrier 120 may be unfolded using the second carrier driving mechanism, as shown in fig. 3. Each second bearing frame 120 is provided with a solar cell, so that when the second bearing frames 120 are unfolded, the solar cell on each second bearing frame 120 faces the sun, and the power generation amount of the solar power generation system can be increased.

In the present invention, the manner in which the second carrier 120 is unfolded is not particularly limited. In the embodiment shown in fig. 3, the second carrier 120 is deployed in an extended manner. However, the present invention is not limited thereto.

For example, in the embodiment shown in fig. 6, the first and second carriers are each fan-shaped structures, with the first and second carriers being hinged at a central corner. When deployed, the plurality of second carriers are deployed in a rotating manner.

In the present invention, the specific number of the second carriers 120 is not particularly limited. For example, in the embodiment shown in fig. 3, the carriers 100 comprise four second carriers, and in the embodiment shown in fig. 6, the carriers 100 comprise six second carriers.

Of course, other unfolding methods may be used to unfold the plurality of second carriers 120, and will not be described in detail herein.

As a preferred embodiment of the present invention, as shown in fig. 4, the first carrier 110 includes a loading plate 111 and a mounting frame 112 provided on the first carrier. The first bearing surface is located on the bearing plate 111, and the mounting frame 112 extends in a direction away from the first bearing surface. The mounting frame 112 and the carrier plate 111 enclose a space for accommodating the plurality of second carriers 120. The mounting frame 112 is provided with a plurality of outlets 112a, one for each second carrier 120, and the second carriers can pass through the corresponding outlets.

When the loading ledges are transported and the angle of the first loading ledge is adjusted, the plurality of second loading ledges 120 are retracted into the space enclosed by the loading ledge 111 and the mounting frame 112. When the angle adjustment of the first carriers 110 is completed, the respective second carriers 120 are driven to protrude from the corresponding outlets.

In the present invention, there is no particular limitation on the specific structures of the first and second carriers, and for convenience of processing and manufacturing, it is preferable that in the specific embodiment shown in fig. 1 to 3, the carrier plate 111 is a rectangular plate, the mounting frame 112 is a rectangular frame, and each of the second carriers 120 is a rectangular plate.

In order to increase the surface area of the carrying surface without increasing the total weight, the length of the sides of the rectangular plate may preferably be between 1.2m and 1.5 m.

For ease of transportation, it is preferred that the carrier includes a locking mechanism in a normally locked state in which the locking mechanism is capable of locking the second carrier within the space of the first carrier and the locking mechanism is capable of unlocking the second carrier upon receipt of a deployment control signal from a control module.

In order to reduce the overall weight of the solar cell carrier assembly, it is preferable that the carrier plate has a plurality of first lightening holes formed thereon, and the second carrier plate has a plurality of second lightening holes formed thereon.

In the present invention, there is no particular requirement for the second carriage drive mechanism. For example, the second carrier driving mechanism may include a plurality of collapsible piston cylinders, one end of each piston cylinder being fixed to the first carrier and the other end of each piston cylinder being fixed to the corresponding second carrier, the second carrier being driven to extend or retract by controlling the collapsible state of the piston cylinders.

In the particular embodiment shown in fig. 4, the second carriage drive mechanism includes a plurality of lead screw sets 150, one lead screw set 150 for each second carriage 120. Each lead screw set 150 includes a lead screw 151, a nut 152 engaged with the lead screw 151, and a motor (not shown) driving the lead screw 151 to rotate. The axial direction of the screw 151 coincides with the moving direction of the corresponding second carriage 120, the screw 151 of the screw group 150 is fixed to the first carriage 110, and the nut of the screw group 151 is fixed to the second carriage 120 corresponding to the screw group 150.

The motor is electrically connected with the control module, and when the motor receives a telescopic control signal sent by the control module, the motor drives the screw to rotate. The control module may send two signals to the electrode, one to control the extension of the second carrier and the other to control the retraction of the second carrier. Preferably, the motor may be a stepper motor.

In the present invention, a plurality of solar cells may be respectively disposed on the first and

second carriers

110 and 120, and electric energy generated by the solar cells may be input to the storage battery by using wires for storage.

To facilitate the telescoping of the second carrier and reduce the number of wires, it is preferable that the first carrier 110 has a first input port and the second carrier 120 has a second input port. The first input port is used for connecting to the output terminals of the solar cells arranged on the first carrier 110, and the second input port is used for connecting to the output terminals of the solar cells on the second carrier 120. The mounting frame 112 is provided with a plurality of conductive rails 160, and the plurality of conductive rails 160 correspond to the plurality of second carriers 120 one to one. The sides of the second carrier 120 are provided with electrically conductive heads 121, which electrically conductive heads 121 are in contact with respective electrically conductive tracks 160, and which electrically conductive tracks are electrically connected with the first input port and/or the second input port.

Due to the arrangement of the conductive guide rail and the conductive head, a flexible electric wire does not need to be arranged in the solar cell bearing assembly, so that the phenomena of winding, wire breakage and the like do not occur, the service life of the solar cell bearing assembly is prolonged, and the safety of the solar cell bearing assembly is also improved.

Preferably, an output port electrically connected to the conductive rail may be provided so that the electric power generated from the solar cell may be output to the storage battery through the conductive rail.

In order to improve safety when the second carrier 120 is unfolded, prevent obstacles from damaging the solar cell carrier assembly, and prevent the solar cell carrier assembly from causing danger to surrounding pedestrians, vehicles, and the like, it is preferable that the solar cell carrier assembly further includes a first ranging radar 170, as shown in fig. 3, and at least one second carrier 120 has the ranging radar 120 disposed thereon. When the first ranging radar 170 monitors that an obstacle exists in a preset range of the ranging radar, a first obstacle alarm signal is sent to the control module, and the control module can control the second bearing frame provided with the ranging radar to retract after receiving the first obstacle alarm signal.

For example, when the solar cell carrier assembly carrying the solar cell is disposed on the open ground, if an obstacle enters the detection range of the first distance radar 170, the corresponding second carrier is controlled to retract, so as to prevent the obstacle from hitting the second carrier.

Preferably, the solar cell bearing assembly further comprises a second ranging radar arranged on the first bearing frame, an output end of the second ranging radar is connected with the control module, when the second ranging radar monitors that an obstacle exists in a preset range of the second ranging radar, a second obstacle alarm signal is sent to the control module, and the control module can control the angle adjusting mechanism to stop driving after receiving the second obstacle alarm signal.

The working principle of the second range radar is the same as that of the first range radar. When the obstacle enters the detection range of the second ranging radar, the angle adjusting mechanism stops driving, so that the obstacle can be prevented from being fitted to the first bearing frame.

In the invention, only the first ranging radar can be arranged, only the second ranging radar can be arranged, and the second ranging radar can be arranged at the same time when the first ranging radar is arranged.

In the present invention, the number and arrangement positions of the ranging radars are not particularly specified. In the embodiment shown in fig. 3, two distance measuring radars are arranged on the end face of each second carriage 120.

In order to prevent a relatively small obstacle which is difficult to be monitored by a ranging radar from obstructing the solar cell carrier assembly, preferably, the solar cell carrier assembly further includes a pressure sensor, an output end of the pressure sensor is connected with an input end of the control module, the pressure sensor is used for detecting pressure applied to the second carrier driving mechanism and generating and sending a signal representing the pressure applied to the second carrier driving mechanism, the control module receives the signal representing the pressure applied to the second carrier driving mechanism and then judges whether the pressure applied to the second carrier driving mechanism is greater than a preset pressure, and when the pressure applied to the second carrier driving mechanism is greater than the preset pressure, the control module generates a third obstacle alarm signal.

In the present invention, the solar cell carrier module may be mounted on a vehicle. If the pressure experienced by the second carrier drive mechanism during vehicle travel exceeds the predetermined pressure, indicating that the second carrier may become entangled with the string or encounter another obstacle, the control module generates the third obstacle alert signal. The control module may send the third obstacle warning signal to a monitoring device (e.g., a driver's mobile phone, a cab computer, etc.), and the driver or other operator may stop traveling after finding the third obstacle warning signal and then remove the third obstacle warning signal.

If the pressure experienced by the second carrier drive mechanism during the unwinding of the second carrier exceeds the predetermined pressure, indicating that the second carrier may be snagged by a string or encounter another obstacle, the control module generates the third obstacle alert signal. At the same time, the control module may control the second carriage drive mechanism to stop driving the second carriage. The control module may send the third obstacle warning signal to a monitoring device (e.g., a driver's mobile phone, a cab computer, etc.), and the driver or other operator may find the third obstacle warning signal to clear the third obstacle.

The solar cell bearing assembly can be only provided with a ranging radar (comprising at least one of the first ranging radar and the second ranging radar) or only provided with a pressure sensor.

Preferably, the solar cell may be provided with the ranging radar and the pressure sensor at the same time. The ranging radar is used for detecting an obstacle with a large volume and controlling the second bearing frame to avoid before the obstacle is touched; the pressure sensor is used for detecting an obstacle with a small volume and braking after the obstacle is hit. Therefore, the solar cell bearing assembly can be better protected.

Preferably, the solar cell bearing assembly further comprises a resistance sensor, an output end of the resistance sensor is connected with an input end of the control module, the resistance sensor is used for detecting resistance received by the angle adjusting mechanism and generating and sending a signal representing the resistance received by the angle adjusting mechanism, the control module receives the signal representing the resistance received by the angle adjusting mechanism and then judges whether the resistance received by the angle adjusting mechanism is greater than a preset resistance, and when the resistance received by the angle adjusting mechanism is greater than the preset resistance, the control module generates a fourth obstacle alarm signal.

When the angle adjusting mechanism drives the first bearing frame to rotate and adjust the orientation of the first bearing frame, if the resistance sensor detects that the resistance applied to the angle adjusting mechanism exceeds the preset resistance, the first bearing frame is indicated to be possibly wound by thin wires or meets other obstacles, and the control module generates the fourth obstacle alarm signal. The control module may send the third obstacle warning signal to a monitoring device (e.g., a driver's mobile phone, a cab computer, etc.), and the driver or other operator may stop traveling after finding the third obstacle warning signal and then remove the third obstacle warning signal.

In the present invention, only the pressure sensor may be provided, only the resistance sensor may be provided, or both the pressure sensor and the resistance sensor may be provided.

Preferably, the solar cell carrier assembly may further include an alarm. The control module can send the first obstacle alarm signal, the second obstacle alarm signal, the third obstacle alarm signal and the fourth obstacle alarm signal to the alarm, and the alarm sends out an alarm signal when receiving any one or any several of the first obstacle alarm signal, the second obstacle alarm signal, the third obstacle alarm signal and the fourth obstacle alarm signal so as to better remind an operator and further avoid the damage of the solar cell bearing assembly by obstacles.

In the present invention, there is no particular requirement for the specific structure of the angle adjustment mechanism, and as a preferred embodiment, the angle adjustment mechanism includes a horizontal rotation device for driving the carriage to rotate about a vertical line, and an angle adjustment device for adjusting the angle between the carriage and a horizontal plane.

As shown in fig. 1 and 2, when adjusting the angle of the first bearing frame, the first bearing frame is first driven by a horizontal rotating device to rotate an angle α around a vertical line, and then the angle between the first bearing frame and a horizontal plane is adjusted by an angle adjusting device so that an angle β exists between the first bearing surface and the horizontal plane, and at this time, the first bearing surface is opposite to the sun. In the present invention, the maximum value of the angle β is determined by the position of the solar cell carrier assembly, and usually, the angle β is 60 ° to meet the requirement.

In the present invention, there is no particular requirement on the specific structure of the telescopic rod 140. For example, the telescopic rod may be a hydraulic telescopic rod or a pneumatic telescopic rod.

When the telescopic rod 140 is a hydraulic telescopic rod or a pneumatic telescopic rod, the telescopic rod 140 comprises a piston cylinder and an electromagnetic valve, a rod cavity and a rodless cavity of a cylinder barrel of the piston cylinder are respectively communicated with a fluid source through a pipeline, and the electromagnetic valve is arranged on the pipeline. And the control end of the electromagnetic valve is electrically connected with the control module. When the telescopic rod is required to be extended, the control module sends a first control signal to the control end of the electromagnetic valve, so that the rodless cavity is communicated with the fluid source, and the fluid flows into the rodless cavity to push out the piston rod; when the telescopic rod needs to be retracted, a human control signal is sent to the control end of the electromagnetic valve by the control module, so that the rod cavity is communicated with the fluid source, and the fluid flows into the rod cavity to push the piston rod back.

When the telescopic rod is a hydraulic telescopic rod, the fluid is hydraulic oil; when the telescopic rod is a pneumatic telescopic rod, the fluid is dry air.

Preferably, the telescopic rod is a pneumatic telescopic rod. Because gas has certain compressibility, when wind blows against the first bearing surface, the pneumatic telescopic rod can shrink to a certain degree, and therefore the solar cell bearing assembly can be prevented from being destroyed by wind.

Preferably, the solar cell bearing assembly further comprises a wind sensor, the wind sensor is used for detecting the wind power and sending a signal of the wind power to the control module, and the control module is used for generating an angle adjusting signal according to the wind power and sending the angle adjusting signal to the angle adjusting mechanism. The angle adjusting mechanism drives the first bearing frame to move after receiving the angle adjusting signal so as to reduce the windward area of the first bearing frame and further reduce the whole windward area of the bearing frame.

In the present invention, the position where the wind sensor is disposed is not particularly required. For example, the wind sensor may be disposed on the bearing surface of the carrier, or may be disposed on the back surface of the carrier.

Correspondingly, the wind sensor comprises a front wind sensor and/or a back wind sensor, and the angle adjusting signal comprises a first angle adjusting signal and a second angle adjusting signal;

When wind blows from the back of the bearing device, the windward area of the first bearing frame is firstly reduced until the bearing frame is laid flat, so that the solar cell bearing assembly can be prevented from being blown over.

In order to reduce the overall weight of the solar cell carrier assembly, the carrier is preferably made of any one of titanium alloy, aluminum alloy, carbon fiber, polyvinyl chloride (PVC).

As a second aspect of the present invention, there is provided a solar power generation system, wherein, as shown in fig. 7, the solar power generation system comprises a solar cell (including the solar cell 110a and the solar cell 120a in fig. 7) and the above-mentioned solar cell carrier assembly provided by the present invention, and the solar cell carrier assembly is disposed on the carrier surface.

In order to reduce the overall weight of the solar cell power generation system, preferably, the solar cell comprises a semi-flexible solar cell or a flexible solar cell film.

Preferably, the storage battery can realize the output of 220V and 380V, so that the solar power generation system provided by the invention can quickly meet the special power supply requirements of various power supply positions without power grids. For example, the solar power generation system is applied to the field of geological exploration.

The electric quantity stored in the storage battery can be used for supplying power to vehicles and can also be used as an emergency power supply for nearby areas to supply power to the nearby areas in an emergency mode.

Preferably, the angle adjustment mechanism may be powered by electricity generated by the solar power generation system.

The state of the loading frame comprises the orientation of the loading surface, the unfolding state of the second loading frame and the like. The remote monitoring device can be a mobile phone, a computer and other terminal equipment.

In the present invention, the specific type of the vehicle is not limited, and for example, the vehicle may be any vehicle such as an automobile, an electric vehicle, a ship, and the like.

The solar cell system is small in size and light in weight, and can be installed on a vehicle under the condition that a hoisting machine is not used. Because the solar cell system is extremely light in weight, the energy consumed in the process of moving along with the vehicle is basically negligible, and the original maneuvering performance of the vehicle cannot be influenced by loading the solar cell system.

When the vehicle is a vehicle, the carrier may be arranged on the roof of the vehicle.

It will be understood that the above embodiments are merely exemplary embodiments taken to illustrate the principles of the present invention, which is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
