[0032] The embodiment of the utility model discloses an emergency stop position indication system of a photovoltaic cleaning robot, which is provided with a sensor and a sensing plate respectively installed on the photovoltaic cleaning robot and the photovoltaic component. The sensor can detect the sensing plate during the movement of the photovoltaic cleaning robot, so as to achieve the effect of prompting the photovoltaic cleaning robot that the position is located on the photovoltaic component, so that the photovoltaic cleaning robot can perform an emergency stop operation, ensure that the photovoltaic cleaning robot stops on the photovoltaic component in an emergency, and improve the safety of the photovoltaic cleaning robot.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] In the photovoltaic power generation industry, photovoltaic modules are generally arranged into photovoltaic arrays at the power generation site. The photovoltaic array includes a photovoltaic module row, and the photovoltaic module row includes multiple photovoltaic strings. The photovoltaic string includes multiple photovoltaic modules 301; different photovoltaic strings are supported by different photovoltaic brackets, and adjacent photovoltaic strings are connected by flexible bridges so that the photovoltaic cleaning robot can clean each photovoltaic string of the same photovoltaic module row one by one through the flexible bridges between the photovoltaic strings.

[0035] Those skilled in the art can understand that when a photovoltaic cleaning robot is performing tasks such as cleaning or charging, it needs to be shut down in an emergency if it encounters a sudden strong wind environment; however, if the photovoltaic cleaning robot happens to be shut down in an emergency on a flexible bridge, it still faces the risk of overturning or falling due to the influence of natural environments such as strong winds, so it is necessary to prevent the photovoltaic cleaning robot from being shut down in an emergency on the flexible bridge. Based on this, the embodiment of the utility model provides an emergency stop position indication system for a photovoltaic cleaning robot 100:

[0036] See also Figure 1-7 The emergency stop position indication system of the photovoltaic cleaning robot 100 provided by the embodiment of the utility model includes a sensor 201 and a sensor plate 202; one of the sensor 201 and the sensor plate 202 is fixed to the photovoltaic cleaning robot 100, and the other is fixed to the photovoltaic component 301 of the photovoltaic string, such as: the sensor 201 is fixed to the photovoltaic cleaning robot 100, the sensor plate 202 is fixed to the photovoltaic component 301, or the sensor 201 is fixed to the photovoltaic component 301, and the sensor plate 202 is fixed to the photovoltaic cleaning robot 100; the sensor 201 is used to detect the sensor plate 202 during the movement of the photovoltaic cleaning robot 100, and transmit the detection result to the control unit of the photovoltaic cleaning robot 100, and the control unit performs an emergency stop operation based on the above detection result.

[0037] After applying the above-mentioned emergency stop position indication system, if the photovoltaic cleaning robot 100 encounters a sudden natural environment such as strong wind when performing tasks such as cleaning or charging, the photovoltaic cleaning robot 100 needs to perform an emergency stop operation. At this time, the photovoltaic cleaning robot 100 moves on the photovoltaic component row and drives the sensor 201 or the induction plate 202 installed thereon to move. Only when the sensor 201 and the induction plate 202 installed on the photovoltaic cleaning robot 100 and the photovoltaic component 301 are respectively aligned with each other, the sensor 201 can detect the induction plate 202 and transmit the detection result to the control unit of the photovoltaic cleaning robot 100. The control unit of the photovoltaic cleaning robot 100 can determine that it has reached a safe position, and then perform an emergency stop operation and stop moving.

[0038] Obviously, in the above-mentioned emergency stop position indication system, the sensor 201 and the sensor plate 202 cooperate to achieve the effect of prompting the photovoltaic cleaning robot 100 that the position is located on the photovoltaic component 301, so that the photovoltaic cleaning robot 100 can perform an emergency stop operation, ensuring that the photovoltaic cleaning robot 100 stops urgently on the photovoltaic component 301, thereby improving the safety of the photovoltaic cleaning robot 100.

[0039] In addition, in other emergency situations, such as when the photovoltaic cleaning robot 100 is offline for a long time or when the flexible bridge between adjacent photovoltaic strings in a photovoltaic module row fails, the photovoltaic cleaning robot 100 also needs to perform an emergency shutdown operation. Before performing an emergency shutdown, it can also move to the position where the sensor 201 detects the sensing plate 202 to ensure the safety of the photovoltaic cleaning robot 100.

[0040] In the solution where the sensor 201 is installed on the photovoltaic assembly 301, the sensor 201 and the photovoltaic cleaning robot 100 can be configured to communicate wirelessly to feed back the detection result to the photovoltaic cleaning robot 100. In the solution where the sensor 201 is installed on the photovoltaic cleaning robot 100, the sensor 201 can be configured to communicate wirelessly or by wire with the photovoltaic cleaning robot 100, which is not limited in this embodiment.

[0041] In one embodiment, the sensor 201 is installed on the photovoltaic cleaning robot 100 and is close to the limiting wheel 101 of the photovoltaic cleaning robot 100. In this solution, the sensor 201 is smaller in size, and when it is installed on the photovoltaic cleaning robot 100, there is no need to change the original structure of the photovoltaic cleaning robot, which is convenient for assembly; at the same time, the sensor 201 is close to the limiting wheel 101, and the limiting wheel 101 is distributed at the upper and lower ends of the photovoltaic string, so that the induction plate 202 is correspondingly set at the upper edge and / or lower edge of the photovoltaic string, so as to prevent the induction plate 202 from blocking the photovoltaic module and affecting power generation. The upper end and lower end of the photovoltaic string refer to the upper end and lower end of the photovoltaic string in the normal power generation state.

[0042] Two groups of limiting wheels 101 are provided at any end of the photovoltaic cleaning robot 100; each group includes one limiting wheel 101; or each group includes multiple limiting wheels 101, and all the limiting wheels 101 in each group are coaxially arranged, such as Figure 1 , 2 , 3 ; the axes of the two sets of limiting wheels 101 are parallel to each other; the sensor 201 is located between the two sets of limiting wheels 101 .

[0043] In this solution, the sensor 201 is arranged between the two sets of limiting wheels 101 at the end of the photovoltaic cleaning robot 100, which does not affect the rotation of the two sets of limiting wheels 101, and can also use the two sets of limiting wheels to protect the sensor 201 and prevent the sensor 201 from being damaged by accidental collision.

[0044] In one embodiment, the sensors 201 are provided in plurality and are distributed at both ends of the photovoltaic cleaning robot 100; the induction plates 202 are provided in plurality, including a first induction plate cooperating with the sensor 201 at one end of the photovoltaic cleaning robot 100 and a second induction plate cooperating with the sensor 201 at the other end of the photovoltaic cleaning robot 100. The first induction plate and the second induction plate can be provided in the same number and correspond one to one; the first induction plate and the second induction plate corresponding to each other are respectively installed at the upper end and the lower end of the same horizontal position of the photovoltaic assembly 301, so as to ensure that when the photovoltaic cleaning robot 100 moves to the horizontal position, the sensors 201 at both ends detect the first induction plate and the second induction plate respectively, so as to ensure that when the sensor 201 at one end of the photovoltaic cleaning robot 100 fails, the sensor 201 at the other end can play the function of detecting the induction plate 202, thereby improving reliability. The horizontal position of any point on the photovoltaic assembly 301 refers to the position of any point in the horizontal direction when the photovoltaic assembly 301 is in a normal power generation state.

[0045] The first sensing plate and the second sensing plate can also be arranged to be installed at different horizontal positions of the photovoltaic module 301; accordingly, the number of the first sensing plate and the second sensing plate can be arranged to be the same or different, which is not limited in this embodiment. In this embodiment, the arrangement of the first sensing plate and the second sensing plate is convenient for the user to install the sensing plate 202 at the upper end or the lower end of different horizontal positions on the photovoltaic module 301 according to the construction convenience needs, and can provide more detection positions, so that the photovoltaic cleaning robot 100 can detect the sensing plate 202 more quickly during the movement to perform an emergency stop operation.

[0046] In another embodiment, the sensor 201 may be provided as one and distributed at one end of the photovoltaic cleaning robot 100; accordingly, the induction plate 202 may be provided to include only the induction plate 202 fixed to one end of the photovoltaic string, for cooperating with the sensor 201. In the solution provided in this embodiment, the number of sensors 201 is small and the cost is low.

[0047] For easy installation, the sensing board 202 can be configured to include a board body 223 and a mounting plate 222 fixedly connected to the board body 223; the mounting plate 222 is attached to the back side (i.e., the backlight side) of the frame 311 of the photovoltaic module 301, and the mounting plate 222 is connected to the frame 311; the board body 223 is used to cooperate with the sensor 201, and the board body 223 is located on the backlight side of the photovoltaic module 301.

[0048] The plate body 223 and the mounting plate 222 can be set to be perpendicular to each other. Of course, the angle between the two can also be set to be an acute angle or an obtuse angle. This embodiment does not limit this. It only needs to ensure that after the mounting plate 222 is assembled, the plate body 223 can be detected by the sensor 201 and does not interfere with the movement of the photovoltaic cleaning robot 100.

[0049] According to the structural characteristics of the frame 311 in the existing photovoltaic module 301, the mounting plate 222 and the frame 311 can be arranged to be connected through a single fixing member 203, and the fixing member 203 can be arranged to be a bolt. Of course, the mounting plate 222 and the frame 311 can also be arranged to be welded, connected through multiple fixing members, or connected through a bracket, etc. This embodiment does not limit the connection method of the mounting plate 222 and the frame 311.

[0050] In one embodiment, the induction plate 202 is fixed at a corner of the photovoltaic component 301 , and the corner is close to another photovoltaic component 301 adjacent to the photovoltaic component 301 in the photovoltaic string.

[0051] In this embodiment, the sensing plate 202 is fixed to the photovoltaic module 301 and is close to the middle position of two adjacent photovoltaic modules 301 in the photovoltaic string. It can prompt the photovoltaic cleaning robot 100 to stop at a position close to the middle position of the two adjacent photovoltaic modules 301, preventing the photovoltaic cleaning robot 100 from stopping at the edge of the entire photovoltaic string, further improving the safety of the photovoltaic cleaning robot 100 at the emergency stop position.

[0052] In further embodiments, please refer to Figure 5 A warped edge 221 may be provided on the edge of the mounting plate 222, the warped edge 221 and the plate body 223 are located on both sides of the mounting plate 222, and the warped edge 221 and the plate body 223 are respectively connected to two adjacent edges of the mounting plate 222; the warped edge 221 is attached to the surface of the photovoltaic component 301 facing another adjacent photovoltaic component 301.

[0053] Those skilled in the art will appreciate that when the photovoltaic cleaning robot moves to any photovoltaic string, it may encounter sudden natural conditions such as strong winds. Therefore, in order to improve safety, a plurality of induction plates 202 are provided and distributed in all photovoltaic strings of the photovoltaic component row.

[0054] The following is a way for the photovoltaic cleaning robot to perform emergency shutdown tasks:

[0055] The photovoltaic cleaning robot 100 generally travels on a photovoltaic module row, which includes a plurality of photovoltaic strings connected in sequence through flexible bridges, and the photovoltaic string includes a plurality of photovoltaic modules 301, and adjacent photovoltaic modules 301 are connected through fixed bridges. The induction board 202 in the emergency stop position indication system is fixed on the photovoltaic module 301 connected to the fixed bridge in the photovoltaic string. The photovoltaic cleaning robot 100 can judge whether it passes through the fixed bridge by the current of the motor driving itself, and can also judge whether it passes through the flexible bridge.

[0056] (1) The photovoltaic cleaning robot 100 determines whether a preset condition for emergency shutdown is met.

[0057] The preset conditions include but are not limited to: ① The photovoltaic cleaning robot 100 receives an emergency stop command; ② The photovoltaic cleaning robot 100 is offline for a long time; ③ The flexible bridge frame in the direction of travel of the photovoltaic cleaning robot 100 fails. It can be understood by those skilled in the art that in the event of a sudden strong wind or other natural condition, the remote control platform sends an emergency stop command to the photovoltaic cleaning robot 100 that performs tasks such as cleaning or charging; of course, if the photovoltaic cleaning robot 100 has the function of monitoring the natural environment, its preset conditions may also include ④ The photovoltaic cleaning robot 100 monitors the natural environment conditions that require emergency shutdown. When any of all the preset conditions are met, the subsequent steps are entered.

[0058] (2) The photovoltaic cleaning robot 100 determines whether it is on a fixed bridge of a photovoltaic string, or whether it has just passed a fixed bridge, or whether it has just passed a flexible bridge.

[0059] If the photovoltaic cleaning robot 100 is on the fixed bridge of the photovoltaic string, the sensor 201 installed on the photovoltaic cleaning robot 100 detects the sensor plate 202 installed on the photovoltaic component 301. The photovoltaic cleaning robot 100 records the current direction of travel and continues to move forward until it passes the fixed bridge, and then the photovoltaic cleaning robot 100 performs an emergency stop operation.

[0060] If the photovoltaic cleaning robot 100 has just passed the fixed bridge, the photovoltaic cleaning robot 100 records the current direction of travel and then moves in the opposite direction until the sensor 201 installed on the photovoltaic cleaning robot 100 detects the induction plate 202 installed on the photovoltaic component 301, and after the photovoltaic cleaning robot 100 has completely passed the fixed bridge, the photovoltaic cleaning robot 100 performs an emergency stop operation.

[0061] If the photovoltaic cleaning robot 100 has just passed the flexible bridge, the photovoltaic cleaning robot 100 records the current direction of travel and continues to move until the sensor 201 installed on the photovoltaic cleaning robot 100 detects the sensor plate 202 installed on the photovoltaic component 301, and the photovoltaic cleaning robot 100 performs an emergency stop operation after completely passing the fixed bridge.

[0062] The emergency stop position indication system provided in this embodiment utilizes the photovoltaic cleaning robot 100 and the photovoltaic module 301 to be equipped with a sensor 201 and a sensor plate 202 respectively, which effectively solves the self-protection problem of the photovoltaic cleaning robot 100 when encountering sudden harsh environments when running on the photovoltaic string.

[0063] In addition, the induction board 202 can be randomly installed on any photovoltaic module in the photovoltaic string, has the flexibility of variable position, and a simple fixed structure; at the same time, the induction board 202 is assembled using the frame 311 of the photovoltaic module 301, has a simple structure, is easy to install, and saves costs.

[0064] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0065] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
