Technical Field

[0001] The present application relates to the technical field of shuttle buses, and in particular to a shuttle bus and a photovoltaic cleaning device. Background Art

[0002] In recent years, my country's cumulative installed capacity of photovoltaic power generation has grown rapidly. Photovoltaic operation and maintenance is key to ensuring the safe and stable operation of photovoltaic modules, and the market demand for photovoltaic operation and maintenance has increased accordingly. Among them, regular cleaning is one of the key aspects of photovoltaic operation and maintenance. Regular cleaning of photovoltaic panels can prevent the accumulation of dust and stains, thereby improving power generation efficiency. Compared with manual cleaning, photovoltaic cleaning robots can automatically clean photovoltaic modules, effectively saving manpower. Existing photovoltaic cleaning robots are usually installed at the end of a row of photovoltaic modules and walk along the edges of the photovoltaic modules to clean the row of photovoltaic modules. These photovoltaic cleaning robots can clean a continuous row of photovoltaic modules without interruption, but cannot clean multiple rows of photovoltaic modules.

[0003] To improve the efficiency of photovoltaic cleaning robots, existing technologies have deployed a ferry system in photovoltaic sites. Through the coordination of shuttle buses and tracks, photovoltaic cleaning robots can move between different rows of photovoltaic panels via the shuttle buses, thereby achieving multi-row cleaning. The shuttle buses used to carry photovoltaic cleaning robots have the following problems during operation:

[0004] When there is a slope or strong wind, the shuttle bus is prone to slipping of the running wheels, resulting in inaccurate positioning. In addition, the overall length of the shuttle bus is long, the transportation cost is high, and the lifting is difficult. Utility Model Content

[0008] Among them, the shuttle bus rotates through a motor-driven gear. Due to the action of the gear rack, the shuttle bus is not easily affected by external forces and slides, making the positioning of the shuttle bus more accurate. In addition, the shuttle bus adopts a modular design and is divided into a front part and a body part. The front part has a complex structure but a small size and can be assembled in the factory with low transportation cost and low lifting difficulty. The body includes a frame with a simple structure.

[0009] Furthermore, the power device also includes a bearing and a transmission shaft, one end of the transmission shaft is connected to the bearing, the other end of the transmission shaft is connected to the output end of the motor, and the gear is sleeved on the transmission shaft.

[0010] Furthermore, the power device also includes a brake system, which is used to control the braking of the motor.

[0011] Furthermore, the shuttle bus includes a first structural beam and a second structural beam perpendicular to the first structural beam, the first structural beam extends along the running direction of the shuttle bus; the first structural beam and the second structural beam are arranged to form a frame.

[0012] Furthermore, the first structural beam and the second structural beam are detachably connected.

[0013] Furthermore, the first structural beam includes a left structural beam and a right structural beam, one end of the second structural beam is connected to the left structural beam, and the other end of the second structural beam is connected to the right structural beam; the ferry car also includes auxiliary wheels, the auxiliary wheels include a left wheel and a right wheel, the left wheel is fixed to the left structural beam, and the right wheel is fixed to the right structural beam, the left wheel and the right wheel are arranged opposite to each other and are both used to contact the side of the track.

[0016] In a second aspect, the present application provides a photovoltaic cleaning device including the shuttle bus of the first aspect, wherein the photovoltaic cleaning device includes a track, a rack is provided on the track, and the rack is meshed with a gear.

[0017] Because the photovoltaic cleaning device of the present application includes the shuttle bus of the first aspect, even when the shuttle bus stops, the rack on the track and the gear of the shuttle bus are engaged, making the shuttle bus less likely to slip and more accurately positioned. Moreover, the front and body of the shuttle bus are detachably connected. The front structure is relatively complex, but the volume is small and can be assembled in the factory. The frame of the body can be assembled on site. Therefore, the overall transportation cost of the shuttle bus is low and the lifting difficulty is relatively small.

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] The shuttle can be used to switch the photovoltaic cleaning robot between different rows of photovoltaic modules, so as to realize continuous cleaning of multiple rows of photovoltaic modules by the photovoltaic cleaning robot, thereby effectively improving the cleaning efficiency of the photovoltaic cleaning robot. However, the overall length of the existing shuttle is relatively long, the transportation cost is high, and the hoisting difficulty is large; moreover, when there is a slope or strong wind, the running wheel of the shuttle is prone to slip, resulting in inaccurate positioning.

[0034] Therefore, in the embodiments of the present application, a shuttle is provided, Figure 1 FIG. 1 is a structural schematic diagram of a shuttle according to an embodiment of the present application, Figure 2 FIG. 2 is a schematic diagram of the internal structure of a box of a vehicle head according to an embodiment of the present application, Figure 3 FIG. 3 is a schematic diagram of the meshing structure of a gear and a rack according to an embodiment of the present application, please refer to Figures 1 to 3 The shuttle 10 includes a vehicle head 100 and a vehicle body 200, wherein the vehicle head 100 includes a box 110 and a power device 120 arranged in the box 110, the power device 120 includes a motor 121 and a gear 122, the output end of the motor 121 is connected with the gear 122, and the gear 122 is used to cooperate with the rack 21 on the track 20 to avoid coasting, thereby improving the positioning accuracy of the shuttle 10. The vehicle body 200 includes a frame 210 that can be assembled, and the frame 210 is detachably connected with the lower part or the bottom of the vehicle head 100.

[0035] It can be understood that the connection mode of the frame 210 and the vehicle head 100 is not limited in the present application, for example, the two can be connected by bolts or screws.

[0036] Among them, the height of the existing shuttle 10 is relatively high, so that when the photovoltaic cleaning machine moves from the photovoltaic module to the shuttle 10, it needs to cross a slope, which not only increases the design of the slope, but also reduces the stability of the operation of the photovoltaic cleaning machine.

[0037] The shuttle bus 10 in the present application separates the front 100 and the body 200, and the body 200 is mainly a frame 210, and the frame 210 is connected to the lower part or bottom of the front 100, so that the height of the body 200 can be effectively lowered. When the photovoltaic sweeper is transferred from the photovoltaic module to the shuttle bus 10, there is no need to cross the slope, the on-site construction is simple and convenient, and the stability of the operation of the photovoltaic sweeper is increased.

[0038] like Figure 1 As shown, the front end 100 and the body 200 are connected by a connecting rod 900. Optionally, the connecting rod 900 is connected to the bottom of the front end 100, and the connecting rod 900 is connected to the bottom of the frame 210. That is, the connecting rod 900 is provided at the bottom of the front end 100 and the body 200 to prevent interference between the connecting rod 900 and the photovoltaic sweeper. Specifically, the connecting rod 900 connects the front end 100 and the body 200 using through-bolts.

[0039] Continue to refer to Figure 2 The power unit 120 further includes a bearing 123 and a transmission shaft 124. One end of the transmission shaft 124 is connected to the bearing 123, and the other end of the transmission shaft 124 is connected to the output end of the motor 121. The gear 122 is sleeved on the transmission shaft 124. The output shaft of the motor 121 drives the transmission shaft 124 to rotate, and the transmission shaft 124 drives the gear 122 to rotate, thereby driving the shuttle 10 to move.

[0040] The motor 121 may be a brushless motor 121. The brushless motor 121 has many advantages, such as high efficiency and energy saving, long life, low noise, good speed regulation performance, no electromagnetic interference, strong adaptability and low maintenance cost.

[0041] You can continue to refer to Figure 2 A positioning sensor 117 is further provided in the box body 110 of the vehicle head 100. The positioning sensor 117 can monitor the position of the shuttle bus 10 on the track 20, so that the shuttle bus 10 can be docked at a preset position.

When the photovoltaic cleaning machine 30 is lowered from the trolley 10 to clean the photovoltaic modules, the brake system controls the braking of the motor 121, and the trolley 10 needs to wait in place until the photovoltaic cleaning machine 30 finishes the cleaning task and is reloaded onto the trolley 10. Meanwhile, the gear 122 and the rack 21 are engaged to prevent the trolley 10 from sliding down the slope, thereby improving the positioning accuracy and wind resistance of the trolley 10.

The battery is arranged in a battery box 700 in the box body 110, and the photovoltaic panel 800 is fixed to the top of the box body 110. Specifically, the photovoltaic panel 800 can be fixedly installed on the end cover 112, thereby improving the wind resistance of the photovoltaic panel 800 and the overall stability of the trolley 10. The trolley 10 of the present application can realize self-charging of the battery by arranging the photovoltaic panel 800, without the need for external power supply, thereby facilitating the popularization and application of the trolley 10.

[0046] The battery box 700 further comprises a fixing structure for fixing the battery and shock-absorbing cotton, to prevent the battery from being damaged by impact under vibration conditions.

[0047] Continuing to refer to Figure 5 and Figure 6 The trolley 10 further comprises a fixing assembly 115 for fixing the trolley 10 to the track 20 when the trolley 10 is stopped. The fixing assembly 115 is arranged on the side of the trolley head 100 and is used for detachable connection with a fixing plate (not shown in the figure) on the track 20. Specifically, the fixing assembly 115 can comprise an electric cylinder 115a and a fixing member 115b. The fixing member 115b is provided with a through hole 01, the fixing plate (not shown in the figure) on the track 20 is provided with a mounting hole, and the telescopic rod of the electric cylinder 115a can pass through the mounting hole and the through hole 01, thereby fixing the trolley 10 to the track 20 and preventing the trolley 10 from being blown off in a strong wind area.

[0048] Optionally, the fixing member 115b can be a U-shaped plate, the bottom plate of the U-shaped plate is fixed to the front of the vehicle 100 and the opening is away from the front of the vehicle 100, and the two symmetrically arranged side panels of the U-shaped plate are provided with through holes 01, so that the fixing plate on the track 20 can be clamped between the two side panels to prevent the fixing plate from falling out, thereby better fixing the front of the vehicle 100 and the track 20.

[0049] It is understandable that the fixing assembly 115 may also be provided on the vehicle body 200 to fix the vehicle body 200 on the track 20 when the shuttle bus 10 stops.

[0050] Figure 7 This is a structural diagram of the support frame of the vehicle head according to an embodiment of the present application, referring to Figure 6 and Figure 7 The front of the vehicle 100 may include a support column 113, which is perpendicular to the end cover 112. The support column 113 can fix the side panel 111. Specifically, the side panel 111 can be fixed to the support column 113 by bolts. The number of support columns 113 is not limited in this application and can be set according to actual needs. Preferably, the front of the vehicle 100 can be provided with four support columns 113, and the four support columns 113 are respectively located at the corners of the front of the vehicle 100.

[0051] Continue to refer to Figure 2 、 Figure 6 and Figure 7 The front end 100 may include a support beam 114, which is perpendicular to the support column 113 and supports the power unit 120. Specifically, the first positioning plate 126 may be fixed to one support beam 114, and the bearing seat 125 may be provided on the other support beam 114. The two support beams 114 are arranged in parallel, and the distance between them is set according to the position and size of the power unit 120 and the track 20.

[0052] Among them, the support column 113 and the support beam 114 can be assembled from profiles or welded with square tubes. Their main function is to support internal components.

[0053] You can continue to refer to Figure 6 The housing 110 of the vehicle head 100 also houses a control box 116, which houses an integrated control panel and a drive unit. The integrated control panel is signal-connected to the positioning sensor 117 and the drive unit, which in turn is signal-connected to the power unit 120 to control the start and stop of the power unit 120. The positioning sensor 117 transmits position signals to the integrated control panel, which analyzes the signals and transmits them to the drive unit, which then controls the start and stop of the motor 121.

[0054] In some optional embodiments, the shuttle bus 10 includes a first structural beam 300 and a second structural beam 400 perpendicular to the first structural beam 300. The first structural beam 300 extends along the running direction of the shuttle bus 10. The first structural beam 300 and the second structural beam 400 are arranged to form a frame 210. It is understood that the frame 210 can be the frame 210 of the vehicle body 200 or the structural frame of the vehicle head 100.

[0055] like Figure 6 and Figure 7 As shown, the first structural beam 300 and the second structural beam 400 are arranged to form a structural frame of the vehicle head 100 . The structural frame is located at the bottom or lower part of the box body 110 , and the support column 113 and the support beam 114 are fixed to the above structural frame.

One end of the second structural beam 400 is connected to the left structural beam 310, and the other end of the second structural beam 400 is connected to the right structural beam 320. The structure of the frame 210 is simple and can effectively reduce the height of the vehicle body 200.

[0057] Reference Figure 6 and Figure 8 The shuttle bus 10 also includes auxiliary wheels 500, which include a left wheel 510 and a right wheel 520. The left wheel 510 is fixed to the left structural beam 310, and the right wheel 520 is fixed to the right structural beam 320. The left wheel 510 and the right wheel 520 are arranged opposite to each other and are both used to contact the side of the track 20, so that they can be stuck on both sides of the track 20 when the shuttle bus 10 is running, thereby preventing the shuttle bus 10 from falling from the track 20 and improving the stability of the shuttle bus 10.

[0058] In some optional embodiments, the shuttle bus 10 further includes at least two running wheels 600, which are fixed to the second structural beam 400. The running wheels 600 are used to contact the surface of the track 20 on which the rack 21 is provided.

[0059] The first structural beam 300 and the second structural beam 400 are detachably connected, thereby facilitating on-site assembly and reducing transportation costs. Optionally, the first structural beam 300 and the second structural beam 400 can both be formed by splicing profiles or square tubes.
