Description

Technical Field

[0002] In photovoltaic power stations, cleaning devices are mainly used to clean dust on photovoltaic modules. In order to achieve cross-row cleaning, ferry devices came into being. Ferry devices mostly adopt a load-bearing mode, that is, the cleaning device is placed on the ferry device. When crossing rows, it is necessary to use a transition bridge or the adjustment structure of the ferry device to align and connect with the photovoltaic modules to realize the ferrying function.

[0003] Most ferry devices are track-type structures. The design phase needs to be combined with the on-site survey report. A high-flatness track needs to be built at the project site.

[0029] The method of using the photovoltaic module ferry cleaning device provided in this application is:

[0030] When the lifting and adjusting unit is in a locked state, the walking unit drives the bracket to move, and the cleaning device is connected to the bracket through the lifting and adjusting unit, so that the cleaning device can move with the bracket. Since the bracket can cross the photovoltaic module, the cleaning device can clean the photovoltaic module in the process of moving with the bracket, and the cleaning device does not need to actively move on the photovoltaic module; or, the ferrying device moves the cleaning device to a set position, that is, the cleaning device reaches the upper side of the photovoltaic module to be cleaned, and then the lifting and adjusting unit is in a separated state, so that the cleaning device is separated from the ferrying device, and the cleaning device actively moves on the photovoltaic module to clean the photovoltaic module. After cleaning, the cleaning device returns to the position of the ferrying device, and the lifting and adjusting unit is in a locked state, and then the cleaning device is moved to the desired position by the ferrying device.

[0031] As can be known from the above-mentioned usage method, the photovoltaic module ferry cleaning equipment provided by the present application drives the cleaning device to move through the ferry device, and the ferry device is moved by the walking unit, that is, a trackless design is realized. Compared with the prior art, there is no need to set up tracks, which reduces the cleaning cost of the photovoltaic module; moreover, in the locked state, the lifting and adjusting unit can drive at least one end of the cleaning device to rise and fall, so that the height of the cleaning device and the inclination angle of the cleaning device relative to the horizontal plane can be adjusted, so that it can be suitable for photovoltaic modules of different heights and photovoltaic modules of different inclination angles, that is, it can be suitable for different photovoltaic modules; at the same time, since the height of the cleaning device and the inclination angle of the cleaning device relative to the horizontal plane can be adjusted, the ferry device can be suitable for different terrains. Therefore, the above-mentioned photovoltaic module ferry cleaning equipment reduces the cleaning cost of photovoltaic modules and can also be suitable for different photovoltaic modules and different terrains.

[0032] At the same time, in the photovoltaic module ferry cleaning equipment provided by the present application, the bracket can span the photovoltaic module, and the cleaning device and the upper surface of the photovoltaic module can be selected for positioning, which is more conducive to the arrangement and perception reliability of the sensor compared with the side positioning of the cleaning device and the photovoltaic module in the prior art; because the brush of the cleaning device is flexible, the above-mentioned positioning method has a higher precision tolerance, reduces the requirements for perception accuracy, and facilitates positioning.

[0033] Moreover, as can be known from the above-mentioned usage method, the photovoltaic module ferry cleaning device provided by the present application has two ways of cleaning photovoltaic modules: the first is that the ferry device drives the cleaning device to move so that the cleaning device can clean the photovoltaic modules; the second is that the ferry device moves the cleaning device to a set position, the cleaning device is separated from the ferry device, and the cleaning device actively moves on the photovoltaic module to clean the photovoltaic module. When the photovoltaic modules in the row where the photovoltaic modules to be cleaned are located are laid continuously and the length of the row is long, the second method can be used for cleaning, thus shortening the travel of the ferry device, reducing the energy consumption of the ferry device, and thus reducing the cleaning cost of the photovoltaic modules.

[0051] like Figure 1 and Figure 6 As shown, the photovoltaic module ferrying and cleaning equipment provided in the embodiment of the present application includes a ferrying device 100 and a cleaning device 200.

[0052] The cleaning device 200 is used to clean the photovoltaic assembly 300 , and the cleaning device 200 can actively move on the photovoltaic assembly 300 to clean the photovoltaic assembly 300 .

[0053] The specific structure of the cleaning device 200 is selected according to actual conditions, and this embodiment does not limit this.

[0054] The ferry device 100 includes: a support 110, a walking unit 120 and a lifting and adjusting unit.

[0055] The support 110 can span the photovoltaic assembly 300 . The walking unit 120 is disposed on the support 110 . The walking unit 120 is used to drive the support 110 to walk so that the cleaning device 200 can clean the photovoltaic assembly 300 .

[0056] The bracket 110 mainly includes a front end, a rear end, and a connecting part connecting the front end and the rear end. The walking unit 120 is arranged at the front end and the rear end. The connecting part is located on the upper side of the photovoltaic component 300 and spans the photovoltaic component 300. The front end of the cleaning device 200 is connected to the front end of the bracket 110, and the rear end of the cleaning device 200 is connected to the rear end of the bracket 110.

[0057] The specific structure of the bracket 110 is selected according to actual conditions, and this embodiment does not limit this.

[0058] The walking unit 120 may be a walking wheel structure or a crawler track structure, which may be selected according to actual conditions, and this embodiment does not limit this.

[0059] The lifting and adjusting unit is arranged on the bracket 110, and the lifting and adjusting unit has: a locked state hinged with the cleaning device 200, and a separated state separated from the cleaning device 200; in the locked state, the lifting and adjusting unit can drive at least one end of the cleaning device 200 to lift and lower.

[0060] On the one hand, in the locked state, the lifting and adjusting unit can drive one end (front end) of the cleaning device 200 to lift and lower, and the lifting and adjusting unit can be selected to be arranged at the front end of the bracket 110. In order to facilitate the lifting and lowering of the cleaning device 200, the lifting and adjusting unit can be selected to be hinged with the front end of the cleaning device 200, and the hinge axis is perpendicular to the vertical direction so that the cleaning device 200 can rotate in the vertical plane.

[0061] If the lifting and adjusting unit can drive the other end (rear end) of the cleaning device 200 to lift in the locked state, the lifting and adjusting unit can be set on the rear end of the bracket 110. In order to facilitate the lifting and lowering of the cleaning device 200, the lifting and adjusting unit can be selected to be hinged with the rear end of the cleaning device 200, and the hinge axis is perpendicular to the vertical direction so that the cleaning device 200 can rotate in the vertical plane.

[0062] If in the locked state, the lifting and adjusting unit can drive both ends (front end and rear end) of the cleaning device 200 to rise and fall. Figure 1 and Figure 2 As shown, the lifting and adjusting unit disposed at the front end of the bracket 110 can be referred to as a front lifting and adjusting unit 130, and the lifting and adjusting unit disposed at the rear end of the bracket 110 can be referred to as a rear lifting and adjusting unit 140. Based on this, the front lifting and adjusting unit 130 is used to be hinged with the front end of the cleaning device 200, and the rear lifting and adjusting unit 140 is used to be hinged with the rear end of the cleaning device 200.

[0063] In order to increase the adjustment range, the lifting adjustment unit can be selected to drive the front and rear ends of the cleaning device 200 to rise and fall in the locked state. In this case, at least one of the front lifting adjustment unit 130 and the rear lifting adjustment unit 140 and the hinge axis of the cleaning device 200 can move along the set direction to ensure that the inclination angle of the cleaning device 200 changes.

[0064] The method for using the photovoltaic assembly ferry cleaning device provided in the above embodiment is:

[0065] When the lifting and adjusting unit is in a locked state, the walking unit 120 drives the bracket 110 to move, and the cleaning device 200 is connected to the bracket 110 through the lifting and adjusting unit, so that the cleaning device 200 can move with the bracket 110. Since the bracket 110 can span the photovoltaic module 300, the cleaning device 200 can clean the photovoltaic module 300 in the process of moving with the bracket 110, and the cleaning device 200 does not need to actively move on the photovoltaic module 300; or, the ferry device 100 moves the cleaning device 200 to a set position, that is, the cleaning device 200 reaches the upper side of the photovoltaic module 300 to be cleaned, and then the lifting and adjusting unit is in a separated state, so that the cleaning device 200 is separated from the ferry device 100, and the cleaning device 200 actively moves on the photovoltaic module 300 to clean the photovoltaic module 300, such as Figure 6 As shown, after cleaning is completed, the cleaning device 200 returns to the position of the ferry device 100, so that the lifting and lowering adjustment unit is in a locked state, and then the cleaning device 200 is moved to the desired position through the ferry device 100.

[0066] As can be known from the above-mentioned method of use, the photovoltaic assembly ferry cleaning device provided by the above-mentioned embodiment drives the cleaning device 200 to move through the ferry device 100, and the ferry device 100 is moved through the walking unit 120, that is, a trackless design is realized. Compared with the prior art, there is no need to set up a track, which reduces the cleaning cost of the photovoltaic assembly 300; and, in the locked state, the lifting and adjusting unit can drive at least one end of the cleaning device 200 to rise and fall, so that the height of the cleaning device 200 and the inclination angle of the cleaning device 200 relative to the horizontal plane can be adjusted, so that it can be applied to photovoltaic assemblies 300 of different heights and photovoltaic assemblies 300 of different inclination angles, that is, it can be applied to different photovoltaic assemblies 300; at the same time, since the height of the cleaning device 200 and the inclination angle of the cleaning device 200 relative to the horizontal plane can be adjusted, the ferry device 100 can be applied to different terrains. Therefore, the above-mentioned photovoltaic assembly ferry cleaning device reduces the cleaning cost of the photovoltaic assembly 300, and can also be applied to different photovoltaic assemblies 300 and different terrains.

[0067] At the same time, in the photovoltaic module ferry cleaning equipment provided by the above embodiment, the bracket 110 can span the photovoltaic module 300, and the upper surface of the cleaning device 200 and the photovoltaic module 300 can be selected for positioning, which is more conducive to the arrangement and perception reliability of the sensor compared to the side positioning of the cleaning device 200 and the photovoltaic module 300 in the prior art; because the brush of the cleaning device 200 is flexible, the above positioning method has a higher accuracy tolerance, reduces the requirements for perception accuracy, and facilitates positioning.

[0068] Moreover, as can be known from the above-mentioned usage method, the photovoltaic module ferry cleaning device provided in the above-mentioned embodiment has two ways of cleaning photovoltaic modules: the first way is that the ferry device 100 drives the cleaning device 200 to move so that the cleaning device 200 cleans the photovoltaic modules 300; the second way is that the ferry device 100 moves the cleaning device 200 to a set position, the cleaning device 200 is separated from the ferry device 100, and the cleaning device 200 actively moves on the photovoltaic modules 300 to clean the photovoltaic modules 300. When the photovoltaic modules 300 in the row where the photovoltaic modules 300 to be cleaned are continuously laid and the length of the row is long, the second way can be used for cleaning, thus shortening the travel of the ferry device 100, reducing the energy consumption of the ferry device 100, and thus reducing the cleaning cost of the photovoltaic modules 300.

[0069] In the photovoltaic module ferry cleaning device, in the locked state, the lifting and adjusting unit can drive at least one end of the cleaning device 200 to lift. In order to achieve the lifting and lowering of the cleaning device 200, the lifting and adjusting unit also includes a lifting and fixing component, a lifting and moving component and a lifting and driving component; wherein the lifting and fixing component is fixed to the bracket 110, the lifting and moving component and the lifting and fixing component slide and cooperate along the lifting direction, and the lifting and driving component is used to drive the lifting and moving component to lift. In the locked state, the lifting and moving component is directly hinged to the cleaning device 200, or the lifting and moving component is indirectly hinged to the cleaning device 200 through other components.

[0070] The specific structures of the lifting and fixing assembly, the lifting and moving assembly and the lifting and driving assembly are selected according to actual conditions.

[0071] In the front lifting adjustment unit 130 and the rear lifting adjustment unit 140 , the structures of the lifting fixing component, the lifting moving component and the lifting driving component may be the same or different.

[0072] The following description will be made by taking the lifting fixing component, the lifting moving component and the lifting driving component in the lifting adjustment unit 140 as an example.

[0073] like Figure 4 As shown, the lifting and fixing assembly includes a guide rail fixing frame 141 and a guide rail 143 . The guide rail fixing frame 141 is fixed to the rear end of the bracket 110 , and the guide rail 143 is fixed to the guide rail fixing frame 141 .

[0074] The lifting and moving assembly includes a rear support frame 145 and a guide roller 144. The guide roller 144 is slidably matched with the guide rail 143. The guide roller 144 is arranged on the rear support frame 145. In the lifting direction, that is, in the vertical direction, the guide roller 144 and the rear support frame 145 are relatively fixed. In the locked state, the rear support frame 145 is directly hinged to the cleaning device 200, or the rear support frame 145 is indirectly hinged to the cleaning device 200 through other components.

[0075] The lifting drive assembly includes a rear lifting drive component 1414 and a transmission mechanism, and the rear lifting drive component 1414 drives the rear support frame 145 to lift and lower through the transmission mechanism. Among them, the rear lifting drive component 1414 can be a motor, a cylinder or other equipment, which is not limited in this embodiment.

[0076] The rear lifting drive component 1414 can be set in the lifting fixed component or in the lifting movable component, depending on the actual situation.

[0077] For ease of installation, the rear lifting drive component 1414 can be selected to be set on the rear support frame 145 of the lifting and moving assembly.

[0078] The type of transmission mechanism is selected according to actual conditions. Exemplarily, the transmission mechanism is a rack and pinion mechanism, which includes: a rack 142 and a gear meshing with the rack (not shown in the figure), the length direction of the rack 142 is the lifting direction, the rack 142 is fixed to the guide rail fixing frame 141, the gear and the rear support frame 145 are relatively fixed in the lifting direction, and the rear lifting drive component 1414 drives the gear to rotate, thereby realizing the reciprocating movement of the gear along the rack 142, that is, realizing the lifting and lowering of the gear, thereby realizing the lifting and lowering of the rear support frame 145, and then realizing the lifting and lowering of the cleaning device 200. In this case, the rack 142 is a component of the lifting and fixing assembly, and the gear is a component of the lifting and moving assembly.

[0079] The transmission mechanism may also be of other types, such as a screw mechanism, etc., which is not limited in this embodiment.

[0080] For the lifting and fixing component, the lifting and moving component and the lifting and driving component in the front lifting and adjusting unit 130 , reference may be made to the above text and will not be described in detail herein.

[0081] In order to realize that the lifting and adjusting unit has a locked state and a separated state, the cleaning device 200 is provided with a cleaning hinge support, and the lifting and adjusting unit also includes a lifting hinge support and a hinge shaft assembly, and the hinge shaft of the hinge shaft assembly can move along its axial direction. In the locked state, the hinge shaft of the hinge shaft assembly passes through the cleaning hinge support and the lifting hinge support; in the separated state, the hinge shaft of the hinge shaft assembly is separated from the cleaning hinge support and / or the lifting hinge support. In the case where the lifting and adjusting unit includes a lifting and moving assembly, the lifting and moving hinge support is fixed to the lifting and moving assembly.

[0082] It should be noted that, when the articulated shaft assembly is provided in the cleaning device 200, the articulated shaft of the articulated shaft assembly can be separated from the lifting hinge support in the separated state; when the articulated shaft assembly is provided in the ferry device 100, the articulated shaft of the articulated shaft assembly can be separated from the cleaning hinge support in the separated state. The axis of the articulated shaft can be perpendicular to the vertical direction and the distribution direction of the front end and the rear end of the bracket 110, so as to ensure that the cleaning device 200 can rotate in the vertical plane.

[0083] In order to facilitate the articulated shaft to move along its axial direction, the articulated shaft assembly may include a first drive device, and the moving part of the first drive device includes the articulated shaft. The specific type of the first drive device is selected according to actual conditions, for example, the first drive device is a cylinder, a hydraulic cylinder or a motor, etc., which is not limited in this embodiment.

[0084] As described above, when the lifting and lowering adjustment unit is locked and can drive the front and rear ends of the cleaning device 200 to lift and lower, the hinge axis of the hinge axis assembly of at least one of the front lifting and lowering adjustment unit 130 and the rear lifting and lowering adjustment unit 140 can move to ensure that the inclination angle of the cleaning device 200 changes. Based on this, the lifting and lowering hinge support of one of the front lifting and lowering adjustment unit 130 and the rear lifting and lowering adjustment unit 140 is provided with a slide groove 1321 for the hinge axis to pass through, and the slide groove 1321 is used to slide with the hinge axis to ensure that the inclination angle of the cleaning device 200 is adjustable; the hinge axis assembly used to cooperate with the slide groove 1321 is provided on the cleaning device 200.

[0085] The shape of the slide groove 1321 is selected according to actual conditions. For example, the slide groove 1321 is an arc-shaped groove, which is not limited in this embodiment.

[0086] In order to facilitate the lifting and adjusting unit to be in a locked state, one of the lifting and adjusting unit and the cleaning device 200 is provided with a positioning rod and the other is provided with a positioning hole for positioning and cooperating with the positioning rod; wherein the positioning rod and / or the positioning hole can move along its axial direction to achieve the cooperation and separation of the positioning rod and the positioning hole.

[0087] The number of positioning holes and positioning rods is selected according to actual conditions, and this embodiment does not limit this.

[0088] In the above-mentioned ferrying device, when the lifting and adjusting unit is in a separated state, the cleaning device 200 is moved to the set position, and the positioning rod and / or the positioning hole are moved along their axial direction to position the positioning rod and the positioning hole; then the lifting and adjusting unit is put into a locked state, and then the positioning rod and / or the positioning hole are moved along their axial direction to separate the positioning rod and the positioning hole.

[0089] In order to simplify the structure and control, the positioning rod or the positioning hole can be selected to be movable along its axial direction.

[0090] In order to facilitate the positioning rod to move along its axial direction, the lifting and adjusting unit may include a second driving device, and the moving part of the second driving device may include the positioning rod; or in order to facilitate the positioning hole to move along its axial direction, the lifting and adjusting unit may be provided with a second driving device, and the moving part of the second driving device may include the positioning hole.

[0091] In order to reduce the weight of the cleaning device 200, a positioning hole may be provided on the cleaning device 200, a positioning member may be provided on the lifting and adjusting unit, and correspondingly, the second driving device may be provided on the lifting and adjusting unit.
