[0003] Therefore, how to improve the operational reliability of the photovoltaic cleaning robot is a technical problem that technical personnel in this field currently need to solve. Utility Model Content

[0004] In view of this, an object of the present utility model is to provide a photovoltaic cleaning robot and a photovoltaic power station to improve the operational reliability of the photovoltaic cleaning robot.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A photovoltaic cleaning robot, comprising:

[0007] A cleaning robot body, which is provided with a walking mechanism;

[0008] The anti-skid assembly comprises a lifting mechanism and an anti-skid member, wherein the lifting mechanism comprises a fixed portion fixedly connected to the cleaning robot body and a telescopic portion arranged on the fixed portion in a manner of actively telescoping along a preset axis, and the anti-skid member is connected to a front end of the telescopic portion in a manner of rotating around the preset axis, so that the telescopic portion can drive the anti-skid member to switch between a first state and a second state;

[0009] Among them, the preset axis is configured as an axis perpendicular to the photovoltaic component where the walking mechanism is located and located at the geometric center of the walking mechanism, the first state is configured as the anti-slip part is in surface contact with the photovoltaic component and applies a preset pressure to the photovoltaic component, and the second state is configured as the anti-slip part is out of contact with the photovoltaic component.

[0010] Optionally, the walking mechanism includes a first track assembly and a second track assembly arranged on both sides of the cleaning robot body, and a track drive for driving the first track assembly and the second track assembly to move.

[0011] Optionally, when the anti-slip member is in the first state, the track drive realizes on-site turning of the cleaning robot body by driving the first track assembly and the second track assembly to rotate in opposite directions.

[0012] Optionally, the anti-slip member includes a supporting foot rotatably connected to the front end of the telescopic portion and an anti-slip structure arranged at the bottom of the supporting foot and used for contacting and cooperating with the surface of the photovoltaic component in the first state.

[0013] Optionally, the anti-skid structure includes one of the five structures of an anti-skid coating, an anti-skid pattern, a vacuum suction cup, an electromagnet and a friction pad, or a combination of at least two of the structures.

[0014] Optionally, the supporting foot is rotatably connected to the front end of the telescopic part via a rotatable connecting piece.

[0015] Optionally, the rotating connection member includes a rotating bearing, an inner ring of the rotating bearing is fixedly connected to the front end of the telescopic part, and an outer ring of the rotating bearing is fixedly connected to the supporting foot via a bearing connecting member.

[0016] Optionally, the fixing portion is detachably mounted on the bottom plate of the cleaning robot body via a driving connecting plate.

[0017] Optionally, the lifting mechanism further comprises a lifting driver for driving the telescopic part to perform telescopic movement relative to the fixed part, and the anti-skid assembly further comprises a pressure monitoring element and a central controller, wherein the pressure monitoring element is arranged on the anti-skid member to monitor the pressure applied by the anti-skid member to the photovoltaic assembly;

[0018] Wherein, the pressure monitoring element and the lifting driver are both connected to the central controller signal.

[0019] Compared with the background technology introduction, in the actual application process of the above-mentioned photovoltaic cleaning robot, since the fixed part of the lifting mechanism of the anti-skid component is fixedly connected to the cleaning robot body, the front end of the telescopic part of the lifting mechanism is rotatably connected to the anti-skid part around a preset axis, and the telescopic part is arranged on the fixed part in a manner of actively telescoping along the preset axis. When the cleaning robot needs to turn, the anti-skid part can be driven by the telescopic part of the lifting mechanism to move to the first state, that is, the anti-skid part is in contact with the surface of the photovoltaic component and applies a preset pressure to the photovoltaic component. At this time, a static friction force is generated between the anti-skid part and the photovoltaic component to prevent the cleaning robot body from skidding, thereby improving the cleaning effect. The robot body has anti-skid capability; at the same time, since the front end of the telescopic part is rotatably connected to the anti-skid part around a preset axis, and since the preset axis is configured as an axis that is perpendicular to the photovoltaic component where the walking mechanism is located and is located at the geometric center of the walking mechanism, the walking parts on both sides of the walking mechanism can be controlled to move in opposite directions, so that the cleaning robot body can be rotated around the preset axis, thereby realizing the on-the-spot turning of the cleaning robot; after the turn is completed, the lifting mechanism drives the anti-skid part to move to the second state through the retraction of the telescopic part, that is, the anti-skid part is out of contact with the photovoltaic component, and the cleaning robot body can now move along the set trajectory and clean.

[0020] It can be seen that the photovoltaic cleaning robot provided by the utility model improves its anti-skid ability through the static friction between the anti-skid parts and the photovoltaic components during the turning process, thereby improving the operating reliability of the photovoltaic cleaning robot; and since the preset axis is set as an axis that is perpendicular to the photovoltaic components where the walking mechanism is located and is located at the geometric center of the walking mechanism, it is only necessary to change the driving strategy of the walking mechanism of the photovoltaic cleaning robot to achieve turning in situ, and there is no need to additionally configure a rotating driving mechanism for the telescopic part to rotate relative to the anti-skid part; at the same time, since the photovoltaic cleaning robot can achieve turning in situ, compared with the traditional turning method that requires a certain turning radius, it can reduce the generation of cleaning dead angles, and at the same time avoid the problem of cleaning dead angles caused by the photovoltaic cleaning robot slipping during turning, which is beneficial to improving the cleaning effect of the photovoltaic cleaning robot; and, through the surface contact between the anti-skid parts and the photovoltaic components, the rollover freedom of the anti-skid parts can be limited, thereby achieving an anti-rollover effect on the cleaning robot body and improving the safety of the photovoltaic cleaning robot.

[0021] In addition, the utility model also provides a photovoltaic power station, including the photovoltaic cleaning robot described in any of the above schemes. Since the above photovoltaic cleaning robot has the above technical effects, the photovoltaic power station with the photovoltaic cleaning robot should also have corresponding technical effects, which will not be repeated here.

[0047] In view of this, the core of the present utility model is to provide a photovoltaic cleaning robot and a photovoltaic power station to improve the operating reliability of the photovoltaic cleaning robot.

[0048] 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.

[0049] like Figures 1 to 5 As shown, an embodiment of the utility model discloses a photovoltaic cleaning robot, including a cleaning robot body 100 and an anti-skid component 200, and the anti-skid capability of the cleaning robot body 100 is improved by the anti-skid component 200, so that the operating reliability of the photovoltaic cleaning robot is improved.

[0050] The cleaning robot body 100 is provided with a cleaning mechanism and a walking mechanism 300. The cleaning mechanism can be arranged at the front end of the cleaning robot body 100, and as long as the cleaning function can be realized, the structure is not specifically limited. The walking mechanism 300 is mainly used for the cleaning robot body 100 to realize the function of walking on the surface of the photovoltaic module, and specifically includes walking parts arranged on both sides of the cleaning robot body 100, and the walking parts on both sides are preferably driven by independent drivers; in addition, the specific structural form of the walking part can be a crawler walking mechanism or a wheeled walking mechanism. In actual application, the configuration can be selected according to actual needs.

[0051] In addition, the anti-skid assembly 200 may specifically include a lifting mechanism 201 and an anti-skid member 202, wherein the lifting mechanism 201 includes a fixed portion 201a fixedly connected to the cleaning robot body 100 and a telescopic portion 201b arranged on the fixed portion 201a in a manner of actively telescoping along a preset axis 203, and the anti-skid member 202 is connected to the front end of the telescopic portion 201b in a manner of rotating around the preset axis 203, so that the telescopic portion 201b can drive the anti-skid member 202 to switch between the first state and the second state. Among them, the preset axis 203 can be specifically configured as an axis perpendicular to the photovoltaic assembly where the walking mechanism 300 is located and located at the geometric center of the walking mechanism 300, the first state is specifically configured as the anti-skid member 202 being in surface contact with the photovoltaic assembly and applying a preset pressure to the photovoltaic assembly, and the second state is specifically configured as the anti-skid member 202 being out of contact with the photovoltaic assembly.

[0052] In actual application of the above-mentioned photovoltaic cleaning robot, since the fixed part 201a of the lifting mechanism 201 of the anti-skid component 200 is fixedly connected to the cleaning robot body 100, the front end of the telescopic part 201b of the lifting mechanism 201 is rotatably connected to the anti-skid part 202 around the preset axis 203, and the telescopic part 201b is arranged on the fixed part 201a in a manner of actively telescoping along the preset axis 203. When the cleaning robot needs to turn, the telescopic part 201b of the lifting mechanism 201 can drive the anti-skid part 202 to move to the first state, that is, the anti-skid part 202 is in contact with the surface of the photovoltaic component and applies a preset pressure to the photovoltaic component. At this time, a static friction force is generated between the anti-skid part 202 and the photovoltaic component to prevent the cleaning robot body 100 from skidding, thereby improving the cleaning efficiency. The robot body has anti-skid capability; at the same time, since the front end of the telescopic portion 201b is rotatably connected to the anti-skid component 202 around the preset axis 203, and since the preset axis 203 is configured as an axis perpendicular to the photovoltaic component where the walking mechanism 300 is located and located at the geometric center of the walking mechanism 300, the walking parts on both sides of the walking mechanism 300 can be controlled to move in opposite directions, so that the cleaning robot body 100 can be rotated around the preset axis 203, thereby realizing the in-situ turning of the cleaning robot; after the turning is completed, the lifting mechanism 201 retracts the telescopic portion 201b to drive the anti-skid component 202 to move to the second state, that is, the anti-skid component 202 is out of contact with the photovoltaic component, and at this time the cleaning robot body 100 can move along the set trajectory and clean.

[0053] It can be seen that during the turning process, the photovoltaic cleaning robot provided by the utility model improves the anti-skid ability through the static friction between the anti-skid part 202 and the photovoltaic component, so that the operation reliability of the photovoltaic cleaning robot is improved; and because the preset axis 203 is set to be perpendicular to the photovoltaic component where the walking mechanism 300 is located and located at the geometric center of the walking mechanism 300, it is only necessary to change the driving strategy of the walking mechanism 300 of the photovoltaic cleaning robot to achieve turning in situ (for example, the walking parts on both sides of the walking mechanism 300, the driving strategy of one side is forward rotation, and the driving strategy of the other side is reverse rotation; for example, the driving strategy of one side is active rotation, and the driving strategy of the other side is reverse rotation). One side driving strategy is driven rotation), and there is no need to additionally configure a rotation driving mechanism for the telescopic part 201b to rotate relative to the anti-slip part 202; at the same time, since the photovoltaic cleaning robot can turn on the spot, compared with the traditional turning method that requires a certain turning radius, it can reduce the generation of cleaning dead angles, and at the same time avoid the problem of cleaning dead angles caused by the photovoltaic cleaning robot slipping due to turning, which is beneficial to improving the cleaning effect of the photovoltaic cleaning robot; and, through the surface contact between the anti-slip part 202 and the photovoltaic component, the rollover freedom of the anti-slip part 202 can also be limited, thereby achieving an anti-rollover effect on the cleaning robot body 100 and improving the safety of the photovoltaic cleaning robot.

[0054] It should be noted that the contact surface shape between the anti-slip part 202 and the photovoltaic module can be any shape such as round, square or elliptical, and as long as the shape can meet the use requirements, it belongs to the protection scope of the present utility model; optionally, the contact surface between the anti-slip part 202 and the photovoltaic module provided in the embodiment of the present utility model is round.

[0055] In some specific embodiments, the walking mechanism 300 may include a first track assembly 301 and a second track assembly 302 disposed on both sides of the cleaning robot body 100, and a track driver 303 for driving the first track assembly 301 and the second track assembly 302 to move. Specifically, when the anti-skid member 202 is in the first state, the track driver 303 drives the first track assembly 301 and the second track assembly 302 to rotate in opposite directions to achieve the on-site turning of the cleaning robot body 100. At this time, the anti-skid member 202 presses against the surface of the photovoltaic module with a preset pressure, thereby ensuring the static friction between the anti-skid member 202 and the photovoltaic module. When the cleaning robot body 100 rotates around the preset axis 203, the front end of the telescopic portion 201b rotates relative to the anti-skid member 202 around the preset axis 203. The first crawler assembly 301 and the second crawler assembly 302 may select two crawler drivers 303 independently, or may share one crawler driver 303, and then switch different transmission modes to connect the first crawler assembly 301 and the second crawler assembly 302. By designing the walking mechanism 300 as the above crawler assembly, the climbing and anti-skid capabilities of the walking mechanism 300 are enhanced.

[0056] Of course, it can be understood that the walking mechanism 300 is designed as the structural form of the above-mentioned crawler assembly, which is only a preferred example of the embodiment of the utility model. In actual application, it can also be designed as a wheeled structure. In actual application, the configuration can be selected according to specific needs, and no more specific limitations are made here.

[0057] In some specific implementations, the anti-skid member 202 may include a support foot 202a rotatably connected to the front end of the telescopic portion 201b and an anti-skid structure 202b disposed at the bottom of the support foot 202a and used to contact and cooperate with the surface of the photovoltaic module in the first state. By designing this structural form, the support foot 202a is used as a rotation support to process the corresponding rotation structure, and the anti-skid structure 202b can be processed on the corresponding structural member to have an anti-skid effect, making the processing of the anti-skid member 202 more convenient and the manufacturing process more clear.

[0058] The specific structural form of the anti-skid structure 202b may include one or a combination of at least two structures such as an anti-skid coating, an anti-skid pattern, a vacuum suction cup, an electromagnet, and a friction pad. In actual application, the corresponding structural form can be selected according to actual needs, as long as the corresponding anti-skid function can be achieved.

[0059] It should be noted that the connection method between the above-mentioned supporting foot 202a and the anti-slip structure 202b can be specifically designed as an integrated structure, or a split fixed connection structure. The specific structural form can be selected according to the specific form of the anti-slip structure, and no further specific limitation is made here.

[0060] It should also be noted that the anti-skid structure 202b can be designed as a component provided at the bottom of the support foot 202a, or can be directly processed and manufactured at the bottom of the support foot 202a, as long as it can meet the use requirements. For example, the anti-skid structure 202b can be an anti-skid coating applied to the bottom of the support foot 202a to increase the friction coefficient of the anti-skid member 202, so that the anti-skid member 202 and the photovoltaic module have a larger anti-skid friction force; or it can be a vacuum suction cup, an electromagnet or a friction pad additionally provided at the bottom of the support foot 202a, through vacuum adsorption, electromagnetic adsorption or friction force; it can also be a convex point, a raised rib or a pattern directly processed at the bottom of the support foot 202a, so as to have a larger friction coefficient, so that the anti-skid member 202 and the photovoltaic module have a larger anti-skid friction force.

[0061] In a further embodiment, the support foot 202a can be rotatably connected to the front end of the telescopic part 201b through a rotating connector 204, so that when the photovoltaic cleaning robot turns, the rotation of the cleaning robot body 100 is supported by the rotating connector 204. The design of the rotating connector 204 makes the rotation connection between the support foot 202a and the telescopic part 201b more stable and reliable, and makes it easier to maintain and replace the rotating structure.

[0062] It should be noted that the above-mentioned rotating connection member 204 can be a bearing or a rotary joint type connection member. As long as it is a connection member type that can achieve a rotating connection between the supporting foot 202a and the front end of the telescopic part 201b, it belongs to the protection scope of the present utility model.

[0063] In an optional specific embodiment, the rotating connecting member 204 may specifically include a rotating bearing, the inner ring of which is fixedly connected to the front end of the telescopic part 201b, and the fixed connection method may be but is not limited to key connection, welding, etc.; the outer ring of the rotating bearing is fixedly connected to the supporting foot 202a through a bearing connecting member 205, and the fixed connection method may be but is not limited to fastener connection, so that the front end of the telescopic part 201b rotates around the preset axis 203 relative to the supporting foot 202a, which is converted into a relative rotation of the inner ring and the outer ring of the bearing, and the rotation is smoother, which makes it easier to achieve the effect of turning on the spot.

[0064] In some other specific embodiments, the above-mentioned fixed part 201a can be specifically but not limited to be detachably mounted on the bottom plate 101 of the cleaning robot body 100 through the driving connecting plate 206. Specifically, a corresponding avoidance opening should be designed on the bottom plate 101 of the cleaning robot body 100, and the avoidance opening is mainly used to provide an avoidance space for the telescopic movement of the telescopic part 201b, and the driving connecting plate fixed to the fixed part 201 can be fixedly connected to the bottom plate 101 through fasteners. By designing the above-mentioned driving connecting plate 206, the fixed connection operation between the fixed part 201a of the lifting mechanism 201 and the cleaning robot body 100 is more convenient.

[0065] Those skilled in the art should be able to understand that the pressure of the anti-slip part 202 on the photovoltaic module needs to be within a preset range to prevent the pressure of the anti-slip part 202 on the photovoltaic module from being too small and failing to prevent skidding, or the pressure of the anti-slip part 202 on the photovoltaic module from being too large and causing damage to the photovoltaic module.

[0066] To this end, the anti-skid component 200 provided by the utility model also includes a pressure monitoring element and a central controller; wherein, the pressure monitoring element is arranged on the anti-skid part 202 to monitor the pressure applied by the anti-skid part 202 to the photovoltaic component, and the lifting mechanism 201 also includes a lifting driver 201c for driving the telescopic part 201b to perform a telescopic movement relative to the fixed part 201a. The pressure monitoring element and the lifting driver 201c are both connected to the central controller signal to monitor the pressure applied by the anti-skid part 202 to the photovoltaic component through the pressure detection element, and convert the monitored pressure value into an electrical signal and transmit it to the central controller. The central controller controls the lifting driver 201c according to a preset pressure range, and drives the extension length of the telescopic part 201b to be controlled by the lifting driver 201c, so that the pressure of the anti-skid part 202 on the photovoltaic component is adjusted.

[0067] In addition, the utility model also provides a photovoltaic power station, including the photovoltaic cleaning robot described in any of the above schemes. Since the above photovoltaic cleaning robot has the above technical effects, the photovoltaic power station with the photovoltaic cleaning robot should also have corresponding technical effects, which will not be repeated here.

In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may include steps or units that are not listed.

[0069] 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.
