Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a photovoltaic robot shuttle device and a photovoltaic cleaning system. Background Technology

[0002] To ensure the power generation efficiency of photovoltaic (PV) arrays, it is typically necessary to use PV cleaning robots to clean the PV panels. PV power plants usually have multiple rows of PV arrays. To improve the utilization rate of PV cleaning robots and reduce cleaning costs, existing technologies generally use PV robot transfer devices to transport the PV cleaning robots from one row of PV arrays to another.

[0003] Existing photovoltaic robot shuttle devices typically consist of two parallel tracks and a shuttle vehicle that rolls along the tracks. Due to variations in actual working conditions, usage time, and the skill level of the construction workers, deviations can easily occur between the tracks, or strong winds can cause the shuttle vehicle to deviate from its course, leading to tipping over, overturning, or other situations where it deviates from the tracks and damages the photovoltaic cleaning robot. In other words, existing technologies cannot automatically correct the shuttle vehicle when it shows signs of tipping over or overturning to prevent it from tipping over.

[0004] Therefore, a photovoltaic robot shuttle device and a photovoltaic cleaning system that can guide the shuttle vehicle and prevent it from tipping over need to be designed. Utility Model Content

[0005] The purpose of this utility model is to address the defects and deficiencies of the existing technology by providing a photovoltaic robot shuttle device and a photovoltaic cleaning system, which solves at least one of the above-mentioned technical problems and has the advantages of guiding the shuttle vehicle and preventing it from tipping over.

[0006] To achieve the above objectives, this utility model provides a photovoltaic robot ferry device, comprising:

[0007] The track consists of two parallel hollow guide rails with openings on the top.

[0008] A shuttle vehicle, movably configured on the track along the track extension direction, includes a chassis;

[0009] The anti-rollover guide assembly is disposed on both sides of the chassis, including a bullseye wheel guide that can extend into the hollow guide rail on the corresponding side and is limited and matched with the inner walls of both sides of the hollow guide rail.

[0010] Optionally, the hollow guide rail has a C-shaped cross-section, and the anti-tipping guide assembly further includes an assembly plate with one end assembled to the bottom of the chassis and the other end extending into the hollow guide rail; the bullseye wheel guide includes two bullseye wheels symmetrically assembled on the assembly plate.

[0011] Optionally, the mounting plate includes an anti-detachment part located inside the hollow guide rail to prevent the bullseye guide from detaching from the opening of the hollow guide rail.

[0012] Optionally, the mounting plate further includes a first transverse section that is assembled and connected to the bottom of the chassis, a first vertical section that is connected to the first transverse section and extends downward, a second transverse section that is connected to the lower end of the first vertical section and extends outward from the chassis, and a second vertical section that is connected to the end of the second transverse section away from the first vertical section and extends at least partially into the hollow guide rail; the two bullseye wheels are symmetrically assembled on the second vertical section by fasteners.

[0013] Optionally, the anti-detachment part includes a first anti-detachment plate disposed on one side of the second vertical section and extending laterally away from the second vertical section, and a second anti-detachment plate disposed on the other side of the second vertical section and extending laterally away from the second vertical section; the distance between the two outer ends of the first anti-detachment plate and the second anti-detachment plate is greater than the opening width of the hollow guide rail.

[0014] Optionally, each side of the chassis is provided with two bullseye wheel guides, and the two bullseye wheel guides are respectively located at the ends of the chassis along its length.

[0015] Optionally, the base plate of the hollow guide rail is provided with water guide holes at intervals in its extending direction.

[0016] Optionally, it also includes a locking mechanism, which includes a locking plate mounted on the hollow guide rail and having a lock hole, and a telescopic locking member mounted on the chassis; the output end of the telescopic locking member can extend into the lock hole of the locking plate for limiting and locking.

[0017] Optionally, the locking plate includes an assembly section fitted to the bottom of the hollow guide rail, an abutting section connected to the assembly section and extending upwards with one side abutting against the inner side of the hollow guide rail, and a locking section connected to the upper end of the abutting section and extending laterally towards the centerline of the rail; the locking hole is vertically disposed in the locking section; the telescopic locking member is vertically disposed on the chassis so that when the output end of the telescopic locking member extends into the locking hole, at least the front-rear freedom of the telescopic locking member is restricted.

[0018] Another aspect of this utility model provides a photovoltaic cleaning system, including a photovoltaic cleaning robot and a photovoltaic robot transfer device as described above. The track of the photovoltaic robot transfer device is set on one side of several rows of photovoltaic arrays, and the photovoltaic robot transfer device is used to transport the photovoltaic cleaning robot from one row of photovoltaic arrays to another row of photovoltaic arrays.

[0019] Compared with the prior art, the advantages of this application are:

[0020] Because the photovoltaic robot shuttle device uses two parallel hollow guide rails with openings on the top, the chassis of the shuttle vehicle is equipped with an anti-tipping guide assembly that includes bullseye wheel guides that can extend into the hollow guide rails on the corresponding side and are limited and matched with the inner walls of the hollow guide rails on both sides. In this way, when the shuttle vehicle tends to tip over or overturn due to strong winds or other factors, the bullseye wheel guides roll and slide relative to the inner walls of the hollow guide rails to correct the direction of travel of the shuttle vehicle chassis, so that the shuttle vehicle continues to travel on the two hollow guide rails and avoids tipping over or overturning off the track.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] It should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," "back," "side," and "circumferential" used in this utility model to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used to distinguish multiple parts or structures with the same or similar structures, and do not indicate any special limitation on the arrangement order or connection relationship.

[0039] Please refer to Figures 1 to 8This utility model provides a photovoltaic robot shuttle device 100 for transporting photovoltaic cleaning robots (not shown) between multiple rows of photovoltaic arrays (not shown in the figure), enabling the photovoltaic cleaning robots to clean the multiple rows of photovoltaic arrays. The photovoltaic robot shuttle device 100 includes: a track 1, a shuttle vehicle, and an anti-tipping guide assembly 4. The track 1 is located on one side of several rows of photovoltaic arrays and includes two parallel hollow guide rails 11 with openings at the top. Optionally, the hollow guide rails 11 are made of stainless steel or an alloy with strong support and hardness. The shuttle vehicle is movably configured on the track 1 along its extension direction and includes a chassis 2 and a shuttle vehicle body (not shown in the figure) configured on the chassis 2. Specifically, the shuttle vehicle body is prior art and will not be elaborated upon here. Optionally, the chassis 2 is a frame structure formed by splicing several square tubes 21 with fasteners to accommodate and support the shuttle vehicle body. A set of traveling wheels 3 is mounted on the underside of the chassis 2, and the traveling wheels 31 in the set of traveling wheels 3 roll in contact with the upper surface of the hollow guide rail 11. Specifically, in this embodiment, a set of traveling wheels 3 is mounted on both the front and rear ends of the shuttle vehicle on the chassis 2, and one set of traveling wheels 31 is driven by a drive motor (not shown in the figure) to make the shuttle vehicle move in the extension direction of the track 1. The anti-tipping guide assembly 4 is disposed on both sides of the chassis 2, including a bullseye wheel guide 41 that can extend into the hollow guide rail 11 on the corresponding side and is limited in contact with the inner walls on both sides of the hollow guide rail 11.

[0040] Thus, when the shuttle bus is in danger of tipping over or overturning due to strong winds or other factors, the bullseye guide 41 can roll and slide relative to the inner wall of the hollow guide rail 11 to guide the direction of travel of the chassis 2 of the shuttle bus, so that the shuttle bus can continue to travel on the two hollow guide rails 11 and avoid tipping over or overturning off the track 1.

[0041] Alternatively, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7In this embodiment, the hollow guide rail 11 has a C-shaped cross-section, and the anti-tipping guide assembly 4 also includes an assembly plate 42; one end of the assembly plate 42 is assembled to the bottom of the chassis 2, and the other end extends into the hollow guide rail 11. Optionally, the assembly plate 42 is fixed to the bottom of the chassis 2 by a first bolt 43. The bullseye wheel guide 41 includes two bullseye wheels 411 symmetrically assembled on the assembly plate 42. That is, the bullseye wheel guide 41 includes two bullseye wheels 411, one bullseye wheel 411 is fixed to the left side of the end of the assembly plate 42 extending into the hollow guide rail 11, and the other bullseye wheel 411 is fixed to the right side of the end of the assembly plate 42 extending into the hollow guide rail 11, and the two bullseye wheels 411 are symmetrically arranged. In this way, the bullseye wheel guide 41 can achieve the guiding function through rolling engagement with the inner walls of both sides of the hollow guide rail 11. Of course, in other embodiments, the two bullseye wheels 411 may also be asymmetrically arranged, that is, located on both sides of the mounting plate 42, but staggered. There is no specific limitation here, as long as they can achieve the guiding function by rolling cooperation with the inner walls of both sides of the hollow guide rail 11. Specifically, the bullseye wheel 411 may include a base 411a with a rotating groove, and a universal ball 411b rolled in the rotating groove of the base 411a by a retainer (not shown in the figure); the base 411a of the bullseye wheel 411 is fixed to the mounting plate 42 by fasteners.

[0042] To prevent the bullseye guide 41 from detaching from the opening of the hollow guide rail 11 and causing the shuttle car to derail from rail 1, alternatively, please refer to... Figure 2 In this embodiment, the assembly plate 42 includes an anti-detachment part located inside the hollow guide rail 11 to prevent the bullseye wheel guide member 41 from detaching from the opening of the hollow guide rail 11. Specifically, please refer to... Figure 6In this embodiment, the assembly plate 42 further includes: a first horizontal section 421, a first vertical section 422, a second horizontal section 423, and a second vertical section 424. The first horizontal section 421 is assembled and connected to the bottom of the chassis 2. Specifically, the first horizontal section 421 can be assembled and connected to the bottom of the chassis 2 via a first bolt 43. The first vertical section 422 is connected to the first horizontal section 421 and extends downward. The second horizontal section 423 is connected to the lower end of the first vertical section 422 and extends outward from the chassis 2. The second vertical section 424 is connected to the end of the second horizontal section 423 away from the first vertical section 422 and at least partially extends into the hollow guide rail 11. Optionally, the assembly plate 42 is integrally formed by bending a metal sheet. Of course, the various parts of the assembly plate 42 can also be a separate structure, connected and fixed into a whole by a connecting structure. There is no limitation here. Two bullseye wheels 411 are symmetrically assembled on the second vertical section 424 by fasteners. The anti-detachment part includes a first anti-detachment plate 425 and a second anti-detachment plate 426. The first anti-detachment plate 425 is disposed on one side of the second vertical section 424 and extends laterally away from the second vertical section 424; the second anti-detachment plate 426 is disposed on the other side of the second vertical section 424 and extends laterally away from the second vertical section 424; and the distance between the two outer ends of the first anti-detachment plate 425 and the second anti-detachment plate 426 is greater than the opening width of the hollow guide rail 11. Thus, during operation, if an external force causes the bullseye wheel guide member 41 to move upward, the first anti-detachment plate 425 and the second anti-detachment plate 426 will be confined within the hollow guide rail 11 by the opening, preventing the bullseye wheel guide member 41 from detaching from the opening of the hollow guide rail 11. That is, the two side walls of the hollow guide rail 11 can restrict the left and right degrees of freedom of the bullseye wheel guide member 41, and the upper side wall of the hollow guide rail 11 and the anti-detachment part cooperate to restrict the up and down degrees of freedom of the bullseye wheel guide member 41, thereby restricting the up and down and left and right degrees of freedom of the shuttle vehicle to prevent the shuttle vehicle from tipping over.

[0043] To achieve better correction, guidance, and anti-tipping effects, optionally, please refer to... Figure 3 and Figure 4 In this embodiment, two bullseye wheel guide members 41 are provided on each side of the chassis 2, and the two bullseye wheel guide members 41 are respectively located at the ends of the chassis 2 along its length. That is, four bullseye wheel guide members 41 are provided on the chassis 2, which makes the shuttle vehicle more stable during operation. Preferably, two bullseye wheel guide members 41 are located in front of the front running wheels 31 and two bullseye wheel guide members 41 are located behind the rear running wheels 31. In this way, the shuttle vehicle can detect the tendency to deviate through the bullseye wheel guide members 41 first, instead of the running wheels 31 deviating a certain distance first before the tendency to deviate is detected, further reducing the risk of the shuttle vehicle tipping over or overturning.

[0044] To prevent rainwater from accumulating inside the hollow guide rail 11 and affecting the operation of the anti-tipping guide assembly 4, optionally, please refer to... Figure 2In this embodiment, the bottom plate of the hollow guide rail 11 is provided with water guiding holes o1 at intervals along its extending direction. In this way, if there is rainwater inside the hollow guide rail 11, it can be discharged in time through the water guiding holes o1.

[0045] To limit the shuttle car's sliding within track 1 when not in operation. Optionally, please refer to... Figure 3 , Figure 5 and Figure 8 In this embodiment, the photovoltaic robot shuttle device 100 further includes a locking mechanism. The locking mechanism includes a locking plate 5 and a telescopic locking member. Specifically, the locking plate 5 has a locking hole o2 and is mounted on the hollow guide rail 11. Specifically, the locking plate 5 is mounted at the stopping position of the track 1. The telescopic locking member is mounted on the chassis 2, and the output end of the telescopic locking member can extend into the locking hole o2 of the locking plate 5 for limiting and locking. Optionally, the telescopic locking member is a push rod motor 6, and its output end is a push rod 61. Specifically, the locking plate 5 includes an assembly section 51, a clamping section 52, and a locking section 53; wherein, the assembly section 51 is assembled and fixed to the bottom of the hollow guide rail 11. Optionally, the assembly section 51 can be fixed to the bottom of the hollow guide rail 11 by a second bolt 54. The clamping section 52 is connected to the assembly section 51 and extends upward, with one side abutting against the inner side of the hollow guide rail 11. The locking section 53 is connected to the upper end of the clamping section 52 and extends laterally towards the centerline of the track 1. The locking hole o2 is vertically disposed in the locking section 53. The telescopic locking member is vertically disposed on the chassis 2 so that when the output end of the telescopic locking member extends into the locking hole o2, it at least restricts the forward and backward freedom of the telescopic locking member. Since the locking mechanism can restrict the forward and backward freedom of the shuttle car, the track 1 can restrict the up and down and left and right freedom of the shuttle car. Thus, when not in operation, the shuttle can be locked at the stop position on the track 1, preventing it from sliding within the track 1 when not in operation.

[0046] Another aspect of this utility model embodiment provides a photovoltaic cleaning system (not shown in the figure), including a photovoltaic cleaning robot (not shown in the figure) and a photovoltaic robot transfer device 100 as described above. The track 1 of the photovoltaic robot transfer device 100 is arranged on one side of several rows of photovoltaic arrays (not shown in the figure), and the photovoltaic robot transfer device 100 is used to transport the photovoltaic cleaning robot from one row of photovoltaic arrays to another row of photovoltaic arrays. The photovoltaic cleaning robot is prior art, so it will not be elaborated upon here. Since this photovoltaic cleaning system possesses all the structures and connections of the photovoltaic robot transfer device 100, it has all the advantages of the photovoltaic robot transfer device 100, which will not be described in detail here.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the substance of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
