Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0029] Please refer to Figure 1 As will be understood by those skilled in the art, the photovoltaic panel 10 is generally installed at an angle relative to the base surface 40, which refers to a horizontal surface such as a rooftop or the ground. In this embodiment, the upper surface 11 of the photovoltaic panel 10 refers to the surface of the photovoltaic panel 10 facing the sun, that is, the surface of the photovoltaic panel 10 that absorbs light energy. In this embodiment, the photovoltaic panel 10 includes a first end and a second end arranged opposite to each other along a first direction, and in the direction of gravity, the first end of the photovoltaic panel 10 is higher than the second end of the photovoltaic panel 10. More specifically, the first end of the photovoltaic panel 10 refers to the end of the photovoltaic panel 10 that is farther from the base surface 40, and the second end of the photovoltaic panel 10 refers to the end of the photovoltaic panel 10 that is closer to the base surface 40. In this embodiment, the side surface 12 of the first end of the photovoltaic panel 10 refers to the surface where the first end of the photovoltaic panel 10 connects to the upper surface 11 of the photovoltaic panel 10.

[0030] Please refer to Figure 1 and Figure 2The water supply device 30 provided in this application embodiment is used to provide cleaning fluid to the photovoltaic panel 10 cleaning device 20. The cleaning device 20 is slidably disposed on the upper surface 11 of the photovoltaic panel 10, and is used to clean the upper surface 11 of the photovoltaic panel 10. Specifically, the cleaning device 20 includes a mounting frame 24, a first rolling assembly 21, a second rolling assembly 22, and a cleaning assembly 23. The mounting frame 24 extends from the first end to the second end. The first rolling assembly 21 is disposed at the first end of the mounting frame 24, and the second rolling assembly 22 is disposed at the second end of the mounting frame 24. The first rolling assembly 21 and the second rolling assembly 22 can drive the mounting frame 24 to move along a second direction. It can be understood that the mounting frame 24 can be driven to reciprocate along the second direction on the upper surface of the photovoltaic panel 10, the second direction being perpendicular to the first direction. The cleaning assembly 23 is disposed on the mounting frame 24 and is used to clean the upper surface 11 of the photovoltaic panel 10. Through the movement of the mounting frame 24, the cleaning assembly 23 is driven to perform a comprehensive cleaning of the surface of the photovoltaic panel 10. It is known that when cleaning the surface of the photovoltaic panel 10, dust on the surface of the photovoltaic panel 10 will be stirred up. After the dust settles, it will adhere to the surface of the photovoltaic panel 10, thus making the cleaning incomplete. Based on this, this application embodiment provides a water supply device 30 to provide cleaning fluid to the cleaning component 23 during the cleaning process, thereby avoiding dust stirring up and working in conjunction with the cleaning device 20 to remove attached foreign matter. Those skilled in the art will understand that the cleaning fluid in this application embodiment can be clean water or a solution containing cleaning agents, etc., and this application embodiment does not make specific limitations.

[0031] Please refer to Figure 1 Specifically, the water supply device 30 includes a water tank 100, a connecting pipe 200, a traveling trolley 300, and a detection component 400. The water tank 100 is fixed to the upper side of the traveling trolley 300. The connecting pipe 200 connects the water tank 100 and the cleaning device 20. Specifically, the connecting pipe 200 is connected to the first end of the mounting bracket 24 of the cleaning device 20, and the other end of the connecting pipe 200 hangs down naturally and is connected to the water tank 100. The cleaning fluid in the water tank 100 can be transported to the cleaning device 20 through the connecting pipe 200. Specifically, the cleaning fluid flows from the connecting pipe 200 to the first end of the photovoltaic panel 10. Since the first end is higher than the second end, the cleaning fluid will flow to the second end. Due to the presence of the cleaning fluid, the cleaning device 20 will not stir up dust during the cleaning process, thereby ensuring the cleaning effect. Those skilled in the art will understand that the water tank 100 is provided with a water inlet for adding cleaning fluid to the water tank 100; at the same time, the water tank 100 is also provided with a water outlet, and the connecting pipe 200 is inserted into the water tank 100 through the water outlet. These are all prior art and will not be described in detail here.

[0032] Please continue to refer to this. Figure 1 In this embodiment, since the cleaning component 23 moves on the upper surface 11 of the photovoltaic panel 10, it will pull on the connecting pipe 200. To ensure the safety of the connecting pipe 200, this embodiment also provides a traveling trolley 300, on which the water tank 100 is mounted. The traveling trolley 300 moves together with the cleaning equipment 20, thereby ensuring the safety of the connecting pipe 200.

[0033] Please refer to Figure 1 and Figure 2 Furthermore, to ensure synchronization between the traveling trolley 300 and the cleaning equipment 20, a detection component 400 is also provided in this embodiment. Specifically, the detection component 400 is fixed to the upper side of the water tank 100, and is used to detect the position of the connecting pipe 200 so that the traveling trolley 300 and the cleaning equipment 20 move synchronously. Those skilled in the art will know that when the traveling trolley 300 and the cleaning equipment 20 are not synchronized, relative movement occurs between them, which pulls on the connecting pipe 200 connecting the water tank 100 and the cleaning component 200, causing the connecting pipe 200 to deviate. In this embodiment, by detecting the direction and amount of deviation of the connecting pipe 200, the traveling path and speed of the traveling trolley 300 are corrected, thereby synchronizing the cleaning equipment 20 and the traveling trolley 300, ensuring the safe use of the connecting pipe 200, and also saving on the amount of connecting water pipe used. Those skilled in the art will understand that, in the embodiments of this application, the synchronization between the walking trolley 300 and the cleaning equipment 20 means that the relative positions of the walking trolley 300 and the cleaning equipment 20 are consistent.

[0034] Please refer to Figure 1 , Figure 2 and Figure 3In some embodiments, the detection assembly 400 includes a bracket 410 and multiple sets of detection sensors 420. One end of the bracket 410 is fixedly connected to the side of the water tank 100 opposite to the traveling trolley 300, and the multiple sets of detection sensors 420 are fixedly connected to the end of the bracket 410 assembly opposite to the water tank 100. The multiple sets of detection sensors 420 form a detection area 430, and the connecting pipe 200 passes through the detection area 430. Specifically, when the connecting pipe 200 is located within the detection area 430, it can be considered that the traveling trolley 300 and the cleaning equipment 20 are operating synchronously. When it is detected that part of the connecting pipe 200 is outside the detection area 430, it can be determined that relative movement has occurred between the traveling trolley 300 and the cleaning equipment 20. Therefore, the speed and / or path of the traveling trolley 300 can be corrected, for example, by increasing the speed of the traveling trolley 300 or adjusting the forward direction of the traveling trolley 300, so that the traveling trolley 300 and the cleaning equipment 20 are synchronized. Those skilled in the art will understand that setting the detection area 430 allows for a certain tolerance between the traveling trolley 300 and the cleaning equipment 20, thus avoiding frequent adjustments while ensuring the safety of the connecting pipe 200 and improving the service life of the traveling trolley 300.

[0035] Please refer to Figure 2 and Figure 3 Specifically, the detection area 430 has a boundary 431, which includes a first boundary 432, a second boundary 433, a third boundary 434, and a fourth boundary 435. The first boundary 432 and the third boundary 434 are disposed opposite to each other, and the second boundary 433 and the fourth boundary 435 are disposed opposite to each other. The first boundary 432 and the second boundary 433 are adjacent to each other, and the first boundary 432 is located in front of the connecting pipe 200 in the direction of movement. Those skilled in the art will understand that in this embodiment, the boundary 431 of the detection area 430 is virtual and does not represent an actual boundary line 431.

[0036] Those skilled in the art will also understand that boundary 431 may include a fifth boundary, a sixth boundary, etc., which can be set as needed. Specifically, when more precise control of the trolley's running path is required, the number of boundaries 431 can be increased, such as six boundaries or ten boundaries. When the trolley 300's running path is relatively simple, fewer boundaries 431 can be set, such as two boundaries or three boundaries. For example, when the trolley 300 is moving on a track, that is, when a track for the trolley 300 is provided on the base surface 40, the positional relationship between the trolley 300 and the cleaning equipment 20 is only synchronous, ahead, or behind. In this case, only one boundary 431 needs to be set in front of and behind the trolley 300 in its running direction. Therefore, those skilled in the art can set the number of boundaries 431 as needed, and this application embodiment does not impose specific limitations.

[0037] Please refer to Figure 1 , Figure 2 and Figure 3 Specifically, in this embodiment, the number of boundaries 431 is preferably four. In this embodiment, two adjacent boundaries 431 can be perpendicular to each other; for example, the first boundary 432 is perpendicular to the second boundary 433 and the fourth boundary 435. In this embodiment, the first boundary 432 is located in front of the moving direction of the connecting pipe 200, and the third boundary 434 is located behind the moving direction of the connecting pipe 200. Therefore, in the moving direction, when the moving speed of the cleaning device 20 is faster than the moving speed of the traveling trolley 300, that is, when the cleaning device 20 is in front of the traveling trolley 300, the connecting pipe 200 will be pulled forward, causing the connecting pipe 200 to shift towards the first boundary 432. When the shift reaches a certain level, the connecting pipe 200 will touch the first boundary 432. That is, when the connecting pipe 200 touches the first boundary 432, it can be determined that the traveling trolley 300 is lagging behind the cleaning device 20. In this situation, the speed of the traveling trolley 300 can be adjusted, for example, by increasing the speed of the traveling trolley 300, to catch up with the cleaning equipment 20. Of course, those skilled in the art will understand that this can also be achieved by reducing the speed of the cleaning equipment 20. This application embodiment does not impose specific limitations, and those skilled in the art can set it according to the actual situation. In this application embodiment, it is preferable to increase the speed of the traveling trolley 300, as this makes it easier to adjust.

[0038] During the process of the trolley 300 chasing the cleaning device 20, the connecting pipe 200 will move relative to the third boundary 434. When the trolley 300 catches up with the cleaning device 20, that is, when the relative position of the cleaning device 20 and the trolley 300 returns to its initial state, the connecting pipe 200 will return to the detection area 430. At this time, it can be determined that the trolley 300 and the cleaning device 20 are moving synchronously. Those skilled in the art will also understand that at this time, the moving speed of the trolley 300 can be set to be the same as the moving speed of the cleaning device 20.

[0039] Please continue to refer to this. Figure 1 , Figure 2 and Figure 3 Similarly, when the connecting pipe 200 contacts the third boundary 434, it can be determined that the traveling trolley 300 is in front of the cleaning device 20. At this time, the speed of the traveling trolley 300 can be appropriately reduced so that the traveling trolley 300 moves synchronously with the cleaning device 20. When the connecting pipe 200 contacts the second boundary 433, it can be determined that the traveling trolley 300 has deviated from the set track. The trajectory of the traveling trolley 300 can be adjusted so that the traveling trolley 300 shifts towards the second boundary 433, thereby returning the traveling trolley 300 to the set track. Similarly, when the connecting pipe 200 contacts the fourth boundary 435, the traveling trolley 300 is adjusted to shift towards the fourth boundary 435, which will not be elaborated here.

[0040] Please refer to Figure 3 In some embodiments, the projections of the first boundary 432, the second boundary 433, the third boundary 434, and the fourth boundary 435 onto the upper surface 11 of the water tank 100 form a closed shape. In this embodiment, since the boundary 431 forms a closed shape, any deviation of the connecting pipe 200 from any direction can be detected. Therefore, the running speed and trajectory of the traveling trolley 300 can be adjusted based on the detection results to ensure the relative position of the traveling trolley 300 and the cleaning equipment 20, thereby ensuring the safe use of the connecting pipe 200.

[0041] Please refer to Figure 2 and Figure 3 In some embodiments, the detection sensor 420 includes a transmitting sensor 421 and a receiving sensor 422, which are arranged opposite to each other and fixedly connected to one end of the bracket 410 assembly away from the water tank 100. The transmitting sensor 421 is used to transmit signals, and the receiving sensor 422 is used to receive signals transmitted by the transmitting sensor 421. The signals between the transmitting sensor 421 and the receiving sensor 422 form the boundary 431.

[0042] Please refer to Figure 2 and Figure 3 Specifically, the bracket 410 includes four uprights 411 and four crossbars 412. The four uprights 411 are fixed to the upper surface 11 of the water tank 100, and the four crossbars 412 are fixed to the side of the four uprights 411 away from the water tank 100, with the four crossbars 412 connected end-to-end to form a rectangle. In this embodiment, the uprights 411 and crossbars 412 can be made of square steel. The detection sensors 420 are fixed to the four crossbars 412. Specifically, the transmitting sensor 421 and receiving sensor 422 in each group of detection sensors 420 are respectively fixed to two oppositely arranged crossbars 412, for example, by bolts. Furthermore, the size of the detection area 430 can be adjusted by adjusting the relative positions between the groups of detection sensors 420; this is prior art and will not be described further in this embodiment. In this embodiment, when the connecting pipe 200 is located between one set of detection sensors 420, the signal emitted by the transmitting sensor 421 is blocked by the connecting pipe 200, thus the receiving sensor cannot receive the signal or the received signal is weakened, thereby determining that the connecting pipe 200 has shifted. Obviously, in this embodiment, the boundary 431 of the detection area 430 is formed by the signal between the transmitting sensor 421 and the receiving sensor 422. Therefore, those skilled in the art will understand that this boundary 431 is virtual and may not actually exist. Therefore, the boundary 431 drawn in the figure to illustrate the detection area 430 should not be considered as having an actual visible boundary 431.

[0043] Please refer to Figure 4 In some other embodiments, the water supply device 30 further includes a protective frame 440, which includes a blocking rod 442 and four vertical rods 441. The four vertical rods 441 are fixed to the upper surface of the traveling trolley 300, wherein two vertical rods 441 are located on the front side of the water tank 100 in the direction of movement, and the other two vertical rods 441 are located on the rear side of the water tank 100 in the direction of movement. The blocking rod 442 is fixed above the two vertical rods 441 located on the front side of the water tank 100. Thus, during the movement of the traveling trolley 300, the blocking rod 442 can block obstacles in front, preventing damage to the detection component 400 from obstacles during the movement of the traveling trolley 300. It is understood that blocking rods 442 can also be set on both sides of the traveling trolley 300 along the direction of movement, which will not be described in detail in this embodiment. When the protective frame 440 is provided, the bracket 410 can utilize the blocking rods 442 and / or vertical rods 441 in the protective frame 440, such as Figure 4 As shown, the embodiments of this application will not be described in detail.

[0044] Please refer to Figure 1 and Figure 2In some embodiments, the boundary 431 is at the same height as the base surface 40. That is, the boundary 431 and the upper surface of the traveling trolley 300 are at the same height. In other words, in this embodiment, the offset of the connecting pipe 200 at the same height is detected. Of course, those skilled in the art can also set the height of the boundary 431 to be different, for example, the height of the first boundary 432 is higher than the height of the second boundary 433. Specifically, those skilled in the art can set it according to the actual situation, such as the wind direction at the construction site, the flatness of the base surface 40, etc., and this embodiment does not impose specific limitations.

[0045] In some embodiments, the distance between the connecting pipe 200 and the boundary 431 is 1-10 times the diameter of the connecting pipe 200. Those skilled in the art will understand that a smaller distance between the connecting pipe 200 and the boundary 431 results in more accurate detection, but also a higher likelihood of false triggering; conversely, a larger distance results in lower detection accuracy, but reduces false triggering. It is understood that during movement, the trolley 300 may encounter bumps caused by unevenness on the base surface 40, or gusts of wind, causing the connecting pipe 200 to sway. If the distance between the connecting pipe 200 and the boundary 431 is too small, the swaying of the connecting pipe 200 may cause it to frequently trigger the detection sensor 420, requiring frequent adjustments to the trolley 300 and thus reducing its service life. If the distance between the connecting pipe 200 and the boundary 431 is too large, the connecting pipe 200 may be stretched to its limit before it even touches the boundary 431. Therefore, in this embodiment, the distance between the connecting pipe 200 and the boundary 431 is set to 1-10 times the diameter of the connecting pipe 200. Specifically, it can be 1, 3, 5, 7, 9, or 10 times the diameter of the connecting pipe 200. Those skilled in the art can set this distance according to actual conditions, such as the allowance length of the connecting pipe 200, the wind speed at the site, and the flatness of the base surface 40. This embodiment does not impose specific limitations.

[0046] Please refer to Figure 3In some embodiments, the distance between the connecting pipe 200 and the first boundary 432, the second boundary 433, the third boundary 434, and the fourth boundary 435 is the same. That is, in this embodiment, the connecting pipe 200 is initially located at the center of the detection area 430. Of course, those skilled in the art can also set different distances to each boundary 431. Specifically, it can be set according to the degree of influence on the operation of the traveling trolley 300. For example, if the impact of the traveling trolley 300 deviating from the set path is large, that is, if the traveling trolley 300 deviates from the second boundary 433 or the third boundary 434, the impact on the water supply is large, then the distance between the second boundary 433 or the third boundary 434 and the connecting pipe 200 can be relatively small.

[0047] Please refer to Figure 1 In some embodiments, the water supply device 30 further includes an adapter pipe 500; the cleaning device 20 includes a mounting plate located at the first end of the photovoltaic panel 10; the adapter pipe 500 is fixedly connected to the mounting plate, with the first end of the adapter pipe 500 facing the upper surface 11 of the photovoltaic panel 10, and the second end of the adapter pipe 500 connected to the connecting pipe 200. Those skilled in the art will understand that the adapter pipe 500 is a rigid pipe, while the connecting pipe 200 is a flexible hose; by providing the rigid adapter pipe 500, the docking of the connecting pipe 200 is facilitated.

[0048] In some embodiments, the second end of the adapter pipe 500 faces the base surface 40, that is, the second end of the adapter pipe 500 is vertically downward. It is understood that since the photovoltaic panel 10 is generally installed at a relatively high height, especially the first end of the photovoltaic panel 10, which can reach two or three meters in height, the connecting pipe 200 will sag due to its own gravity during this process. In this embodiment, the second end of the adapter pipe 500 is set to face the base surface 40, that is, the orientation of the second end of the adapter pipe 500 is consistent with the direction of gravity. Thus, after the connecting pipe 200 and the adapter pipe 500 are connected, the adapter pipe 500 and the connecting pipe 200 are connected in a straight line, and the adapter pipe 500 will not press against the connecting pipe 200, avoiding damage to the connecting pipe 200 by the adapter pipe 500, thereby improving the service life of the connecting pipe 200. Those skilled in the art will also understand that a clamp can be provided at the joint between the adapter pipe 500 and the connecting pipe 200 to ensure a firm connection between the connecting pipe 200 and the adapter pipe 500. Of course, those skilled in the art can also use other methods for connection, such as quick connectors.

[0049] Please refer to Figure 1In some embodiments, the water supply device 30 further includes a switching valve 600, which is disposed on the transfer pipe 500. It is understood that the switching valve 600 can be used to control the flow of cleaning fluid. Those skilled in the art will also understand that the switching valve 600 can be an intelligent control valve such as a solenoid valve. By setting an intelligent control valve such as a solenoid valve, the flow rate of the cleaning fluid can be adjusted at any time, making it suitable for different environments. For example, if the surface of the photovoltaic panel 10 has firmly attached deposits, the flow rate of the cleaning fluid can be increased by the switching valve 600 to achieve a rinsing effect. Specifically, those skilled in the art can adjust it according to the actual situation.

[0050] Please refer to Figure 1 In some embodiments, the water supply device 30 further includes a drive pump 700, which is fixedly connected to the upper surface 11 of the water tank 100 and connected to the connecting pipe 200. The drive pump 700 can pump the cleaning fluid from the water tank 100 and deliver it to the upper surface 11 of the photovoltaic panel 10 through the connecting pipe 200. The drive pump 700 can be an electromagnetic pump, etc. Those skilled in the art can configure it as needed; this is prior art and will not be described further in the embodiments of this application.

[0051] In some embodiments, the end of the connecting pipe 200 facing away from the adapter pipe 500 hangs naturally down to the upper surface of the water tank 100, and extends along the upper surface of the water tank 100 to connect with the drive pump 700. Clearly, the connecting pipe 200 is connected to the water tank 100 via the drive pump 700. Those skilled in the art will understand that the base surface 40 on which the photovoltaic panel 10 is installed, especially the base surface 40 for outdoor photovoltaic panel installation, often exhibits unevenness. When the traveling trolley 300 runs on such a base surface 40, it will inevitably experience unevenness and bumps. As the traveling trolley 300 runs on the uneven base surface 40, the distance between the upper surface of the water tank 100 and the first end of the photovoltaic panel 10 will change; that is, the length of the connecting pipe 200 suspended in the air between the adapter pipe 500 and the water tank 100 will change with the unevenness of the base surface. To avoid the connecting pipe 200 being stretched due to such changes, in this embodiment, the end of the connecting pipe 200 away from the adapter pipe 500 hangs naturally down to the upper surface of the water tank 100. Thus, when encountering undulating surfaces, since the end of the connecting pipe 200 in contact with the water tank 100 is not fixed, the side of the connecting pipe 200 near the water tank 100 can rise and fall with the undulations of the base surface 40. Furthermore, in this embodiment, the connecting pipe 200 bends and extends on the upper surface of the water tank 100 before connecting to the drive pump 700. This provides a margin for variation in the length of the connecting pipe 200 suspended in the air, ensuring that the connecting pipe 200 will not be stretched when its length changes. Those skilled in the art will understand that there is a gap between the projection of the detection component 400 on the upper surface of the water tank 100 and the head of the drive pump 700 on the upper surface of the water tank 100. The connecting pipe 200 bends and spirals within this gap on the upper surface of the water tank. Specifically, the connecting pipe 200 can be bent in an S-shape. Those skilled in the art will also understand that the amount of bending of the connecting pipe 200 on the upper surface of the water tank 100 can be set according to the degree of undulation of the base surface 40. For example, the greater the degree of undulation of the base surface, that is, the greater the change in distance between the base surface 40 and the first end of the photovoltaic panel 10, the greater the change in the length of the connecting pipe 200 suspended in the air. Therefore, the degree of bending of the connecting pipe 200 on the upper surface of the water tank 100 can be set to be greater, thus providing a larger allowance for the connecting pipe 200 on the upper surface of the water tank 100 to accommodate the undulation of the base surface 40. Specifically, those skilled in the art can set this as needed, and the embodiments of this application do not impose specific limitations.

[0052] Please refer to Figure 4In some embodiments, the water supply device 30 further includes a connecting line 800, which connects the traveling trolley 300 and the cleaning device 20. The connecting line 800 is used for communication between the traveling trolley 300 and the cleaning device 20. Those skilled in the art will understand that, to ensure synchronization between the traveling trolley 300 and the cleaning device 20, the connecting line 800 can be used to enable communication between them. This allows them to obtain each other's walking speed and / or positional relationship, further facilitating synchronization adjustment between the traveling trolley 300 and the cleaning device 20. In this embodiment, wired communication is used to ensure signal stability. Of course, those skilled in the art will also understand that the traveling trolley 300 and the cleaning device 20 can also communicate wirelessly. Furthermore, those skilled in the art will also understand that this embodiment includes control devices such as chips, which are prior art and will not be described further in this embodiment.

[0053] Please continue to refer to this. Figure 4 In some embodiments, the water supply device 30 further includes a protective pipe 900, which is sleeved on the outer surface of the connecting pipe 200 and the connecting wire 800. In this embodiment, by sleeved with a protective pipe 900 around the connecting pipe 200 and the connecting wire 800, the connecting wire 800 and the connecting pipe 200 can be protected, preventing damage to the connecting wire 800 or the connecting pipe 200 and extending their service life. The protective pipe 900 can be fixed to the bracket 410, etc., which is prior art and will not be described in detail here.

[0054] Please refer to Figure 1 In some embodiments, the traveling trolley 300 includes tracks or wheels. Whether a tracked or wheeled traveling trolley 300 is used can be determined by those skilled in the art based on actual conditions; this application does not impose specific limitations. However, it should be noted that in this application embodiment, the traveling trolley 300 can also be selected as a trolley that can move in the opposite direction without turning around, that is, the traveling trolley 300 can also reciprocate along the second direction. This allows the cleaning equipment 20 to reciprocate along the second direction on the upper surface of the photovoltaic panel 10, avoiding the traveling trolley 300 turning around and thus improving work efficiency.

[0055] Please refer to Figure 1 , Figure 2 and Figure 3The second aspect of this application provides a photovoltaic panel 10 cleaning system, including a cleaning device 20 and a water supply device 30 as described in any of the above-mentioned embodiments. The cleaning device 20 is movably disposed on the upper surface 11 of the photovoltaic panel 10. The water supply device 30 includes a water tank 100, a connecting pipe 200, a traveling trolley 300, and a detection component 400. The water tank 100 is fixed to the upper side of the traveling trolley 300, and the connecting pipe 200 connects the water tank 100 and the cleaning device 20. The cleaning fluid in the water tank 100 can be transported to the cleaning device 20 through the connecting pipe 200. The detection component 400 is fixed to the upper side of the water tank 100 and is used to detect the position of the connecting pipe 200 so that the traveling trolley 300 and the cleaning device 20 move synchronously. In the embodiments of this application, the above-described water supply device 30 is used, and therefore it also has the technical effects of the above-described water supply device 30, which will not be described again here.
