The support plate is detachably connected to the top of the support member, and the traction member is detachably connected to the mounting seat. The driving member can drive the mounting seat to move along the extension direction of the support member by winding and unwinding the traction member;

[0009] And a control member is electrically connected to the driving member for controlling the operation of the driving member.

[0011] Preferably, a limiting groove is formed in the support member. The extending direction of the limiting groove is the same as that of the support member. A part of the mounting seat is located in the limiting groove.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1

[0041] As Figures 1 to 4 shown, the present invention provides a lifting device for photovoltaic modules for traffic facilities, including:

[0042] A support member 1 for connecting to a traffic facility. When the support member 1 works, the support member 1 is installed on the traffic facility and extends in the vertical direction;

[0043] A mounting seat 2 is installed on the support member 1. The mounting seat 2 can move relative to the support member 1 along the extending direction of the support member 1. When the mounting seat 2 works, the mounting seat 2 is connected to the photovoltaic module;

[0044] A driving assembly 3 includes a support plate 301, a driving member 302 connected to the top of the support plate 301, and a traction member 303 connected to the driving member 302. The support plate 301 is detachably connected to the top of the support member 1, and the traction member 303 is detachably connected to the mounting seat 2. The driving member 302 can drive the mounting seat 2 to move along the extending direction of the support member 1 by winding and unwinding the traction member 303;

[0045] And a control member 4 is electrically connected to the driving member 302 for controlling the operation of the driving member 302.

[0046] The photovoltaic module can supply power to the traffic facility. For example, a single photovoltaic module can supply power to a single or multiple street lamps. When the photovoltaic module is in use, it is installed on the mounting seat 2, and then the support member 1 is connected to the traffic facility. At this time, the traffic facility supports the photovoltaic module, and the photovoltaic module supplies power to the traffic facility. It should be noted that the connection methods described in the present invention can be regarded as detachable connections when not described as fixed connections, such as using a threaded connection method to achieve detachable connection.

[0047] Optionally, the control member 4 is set as a controller; the driving member 302 is set as a winch or a motor; the traction member 303 is set as a traction wire. The operator can control the driving member 302 through the control member 4. When the operator needs to control several control members 4, another existing control device can be set to control these control members 4, or the control member 4 can be installed at the lower end of the support member 1 for easy operation by the operator.

[0048] To avoid situations where pedestrians are injured and photovoltaic modules are damaged due to collisions between photovoltaic modules and pedestrians, and considering factors such as light adjustment, generally, photovoltaic modules need to be installed at a high place, such as in an area 3 meters above the ground. When cleaning personnel need to clean the photovoltaic modules or maintenance personnel need to perform maintenance on the photovoltaic modules, it is not convenient to operate. Through the setting of the driving component 3 and the control component 4, operators such as cleaning personnel and maintenance personnel can control the driving component 3 through the control component 4, and then make the driving part 302 unwind the traction part 303, ultimately realizing the approach of the photovoltaic module to the ground along with the mounting base 2, so as to facilitate the operation of the operator, avoid the need for the operator to use objects such as ladders for operation, speed up the operation progress, and reduce safety risks.

[0049] The driving component 3 is arranged on the top of the support member 1. On the one hand, in some cases, such as in hail weather, the driving component 3 can provide a certain degree of protection for the photovoltaic module; on the other hand, by arranging the driving component 3 at a high place, it is possible to avoid touching pedestrians while avoiding hindering the downward movement of the photovoltaic module.

[0050] The driving component 3 realizes the transfer of the photovoltaic module by winding and unwinding the traction part 303. Compared with the method of setting an electric sliding table or a similar device to drive the photovoltaic module, when the range where the photovoltaic module needs to be transferred is large, the cost is lower.

[0051] A specific method is provided here to help understand the process of the control component 4 controlling the operation of the driving part 302. This method is only for reference and is as follows: Taking a motor controller as an example, the motor controller receives signals from the outside, such as button signals from the operation panel, position signals from sensors, or control instructions from the upper computer.

[0052] The microprocessor inside the controller performs logical judgment and algorithm calculation on these signals to determine the control strategy of the motor; according to the processing result, the controller adjusts the output voltage, current or frequency through the power conversion circuit to generate a control signal; the control signal is transmitted to the motor through electrical connection to drive the motor to operate according to the predetermined speed, rotation direction and start-stop mode; some controllers also include a feedback control loop, which receives the operating state information of the motor (such as position, speed, current, etc.) and adjusts the control signal in real time to achieve more precise control.

[0053] Embodiment 2

[0054] In this embodiment, a limiting groove 101 is formed on the support member 1. The extending direction of the limiting groove 101 is the same as the extending direction of the support member 1. A part of the mounting base 2 is located in the limiting groove 101. The limiting groove 101 has two openings, and one of the openings faces the direction where the support member 1 is close to the support plate 301.

[0055] This embodiment provides a specific connection method between the support member 1 and the mounting base 2. The mounting base 2 is attached to the support member 1 and can move relative to the support member 1 along the extension direction of the support member 1. At the same time, the mounting base 2 can be separated from the support member 1.

[0056] The mounting base 2 can be separated from the support member 1 through the opening on the limiting groove 101 facing the direction of the support member 1 close to the support plate 301. The prerequisite for the separation of the two is the separation of the support plate 301 from the support member 1. When the support plate 301 is connected to the support member 1, the support plate 301 blocks this opening.

[0057] Optionally, the limiting groove 101 has a first opening 1011 and a second opening 1012, and the mounting base 2 can be separated from the support member 1 through the second opening 1012.

[0058] Embodiment 3

[0059] In this embodiment, a cleaning component 5 is provided on one side of the upper end of the support member 1. The cleaning component 5 is connected to the support member 1 through a connecting member, and the cleaning component 5 is used to remove debris on the surface of the photovoltaic module.

[0060] When the support member 1 is working, the cleaning component 5 is on the side of the support member 1 facing away from the traffic facility.

[0061] The above-mentioned debris can refer to various substances, such as dust. When the dust covers the surface of the photovoltaic module, it will affect the working efficiency of the photovoltaic module. Considering the working environment of the photovoltaic module, its surface is easily covered with dust.

[0062] When the support member 1 is working, the cleaning component 5 is on the side of the support member 1 facing away from the traffic facility, and the cleaning component 5 is arranged on one side of the upper end of the support member 1 to avoid the cleaning component 5 touching pedestrians; the driving component 3 can drive the photovoltaic module to approach the cleaning component 5 to facilitate the cleaning component 5 to clean.

[0063] Embodiment 4

[0064] In this embodiment, the cleaning component 5 includes a support mechanism 501 and a cleaning member 502. The support mechanism 501 is connected to the support member 1 through a connecting member, the cleaning member 502 is installed on the support mechanism 501 and can be separated from the support mechanism 501, and the cleaning member 502 is used to remove debris on the surface of the photovoltaic module.

[0065] The actual cleaning structure in the cleaning component 5 is the cleaning member 502, and the support mechanism 501 supports the cleaning member 502. The support mechanism 501 and the cleaning member 502 are separably arranged to facilitate the replacement and cleaning of the cleaning member 502.

[0066] Embodiment 5

[0067] In this embodiment, the support mechanism 501 includes a support portion 5011 and an annular member 5012. The support portion 5011 is connected to the support member 1 through a connecting member. The annular member 5012 is installed on one side of the support portion 5011 close to the support member 1. The support portion 5011 and the annular member 5012 enclose a fixing groove 7 with an opening facing the support member 1, and the cleaning member 502 is placed in the fixing groove 7.

[0068] This embodiment provides a specific installation method for installing the cleaning member 502 on the support mechanism 501. In the support mechanism 501, the support portion 5011 and the annular member 5012 enclose a fixing groove 7 with an opening facing the support member 1, and the cleaning member 502 is placed in the fixing groove 7. At this time, the cleaning member 502 is clamped in the fixing groove 7, realizing the fixation of the cleaning member 502 to prevent it from falling while reducing the difficulty for the operator to separate the cleaning member 502 from the support mechanism 501.

[0069] Embodiment 6

[0070] In this embodiment, the cleaning member 502 is elastic, and each part of the cleaning member 502 can deform under the action of an external force and can automatically recover when the external force disappears.

[0071] The photovoltaic module is installed on one side of the traffic facility. In this environment, due to reasons such as the dust spread driven by the running of the vehicle, the surface of the photovoltaic module is easily covered with dust. For this, the cleaning member 502 is used to deal with this dust. After a certain period of time, the operator replaces the cleaning member 502 or cleans the cleaning member 502.

[0072] The cleaning member 502 is elastic, and each part of the cleaning member 502 can deform under the action of an external force and can automatically recover when the external force disappears. With such a setting, when the driving assembly 3 drives the photovoltaic module to approach the cleaning member 502, the cleaning member 502 deforms and removes some dust on the surface of the photovoltaic module.

[0073] For the cleaning member 502, it can be set as several specific structures or objects. For example, the cleaning member 502 can be set as a sponge cleaning pad or a silicone brush; when the cleaning member 502 is set as an object such as a sponge cleaning pad, water can be appropriately sprayed on the surface of the cleaning member 502 to improve the dust removal effect of the cleaning member 502.

[0074] Embodiment 7

[0075] In this embodiment, a control portion 6 is connected to the support plate 301. The control portion 6 is electrically connected to the driving member 302, and the control portion 6 can automatically control the driving member 302 to operate within a predetermined time period so that the photovoltaic module fits against the cleaning member 502.

[0076] Optionally, the control portion 6 is set as a controller.

[0077] The control unit 6 is electrically connected to the driving member 302. The control unit 6 can automatically control the driving member 302 to operate within a predetermined time period so that the photovoltaic module fits against the cleaning member 502. This predetermined time period can be set to after sunset (such as from 8 pm to 4 am the next day). With such a setting, it is possible to avoid the need for an operator to adjust the position of the photovoltaic module every day.

[0078] It should be noted that when the photovoltaic module remains in contact with the cleaning member 502, the distance between the photovoltaic module and the driving assembly 3 is also correspondingly shortened, and the cleaning member 502 can cooperate with the driving assembly 3 to jointly protect the photovoltaic module.

[0079] A specific method is provided here to help understand the process in which the control unit 6 can automatically control the driving member 302 to operate within a predetermined time period. This method is only for reference and is as follows: Set the time control logic in the hardware or software of the control unit 6. Through the clock and timer module, set a specific time period as the automatic operation period for the photovoltaic module to fit against the cleaning member 502. When the system time enters this period, the microprocessor will trigger the corresponding control logic and send a control signal to the driving member 302 through the output interface; the control unit 6 transmits the control signal to the driving member 302 through electrical connection (such as wires, cables, etc.). After receiving the control signal, the driving member 302 performs corresponding actions to pull the photovoltaic module so that it fits against the cleaning member 502; in some advanced applications, the control unit 6 can also include a feedback mechanism, which monitors the fitting state between the photovoltaic module and the cleaning member 502 through sensors (such as position sensors, force sensors, etc.) and adjusts the control strategy according to the feedback information to ensure the accuracy and stability of the fitting.
