Abstract
Description
Technical Field
[0001] This application relates to the field of photovoltaic technology, and more specifically, to a control method for a photovoltaic snow removal robot and the photovoltaic snow removal robot itself. Background Technology
[0002] In photovoltaic power plants in cold regions, winter snowfall accumulates on the surface of photovoltaic modules, directly obstructing sunlight and causing a significant drop in power generation efficiency, or even a complete halt to power generation in severe cases. Furthermore, the heavy snow accumulation creates a massive snow load, potentially causing irreversible physical damage to the glass covers, frames, and support structures of the photovoltaic modules, and even triggering the collapse of the entire photovoltaic array, resulting in substantial economic losses and safety hazards. Relying solely on roller brushes is insufficient for effectively clearing heavy snow.
[0003] In related technologies, by fixing a scraper to one side of the photovoltaic robot, the snow is pushed forward during the cleaning process, thereby reducing the pressure of the roller brush. However, this will cause the snow to accumulate during the forward pushing process, hindering the photovoltaic robot's progress and thus affecting the overall cleaning action. Summary of the Invention

Detailed Implementation
[0064] The core of this application is to provide a control method for a photovoltaic snow removal robot, which can improve the snow removal efficiency and reliability of the photovoltaic snow removal robot when facing heavy snow or thick snow accumulation.
[0065] Another core aspect of this application is to provide a photovoltaic snow-sweeping robot.
[0066] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0067] In the operation of photovoltaic power plants in cold regions, winter snowfall is an unavoidable natural phenomenon. The snow load generated by the accumulation of snow on photovoltaic modules can have multi-dimensional negative impacts on the photovoltaic system. Therefore, timely snow removal is a key aspect of ensuring the stable operation of the power plant. When clearing heavy snow, relying solely on roller brushes is insufficient for effective cleaning.
[0068] In related technologies, by fixing a scraper to one side of the photovoltaic robot, the snow is pushed forward during the cleaning process, thereby reducing the pressure of the roller brush. However, this will cause the snow to accumulate during the forward pushing process, hindering the photovoltaic robot's progress and thus affecting the overall cleaning action.
[0069] Therefore, this application discloses a control method for a photovoltaic snow-sweeping robot 100, including steps of acquiring operating status parameters and clearing snow. By acquiring the operating status parameters of the photovoltaic snow-sweeping robot 100, different snow removal modes can be switched, avoiding blindly increasing thrust and reducing the load of a single push. Simultaneously, different snow removal methods can be switched for snow of varying thicknesses, effectively solving the problem of traditional robots easily getting stuck and interrupting operations in heavy snow or thick snow conditions, significantly improving the snow removal efficiency and reliability of the photovoltaic snow-sweeping robot 100.
[0070] The control method of the photovoltaic snow sweeping robot 100 disclosed in the embodiments of this application will be explained and described in detail below.
[0071] When snow accumulates on the surface of the photovoltaic module 200, the photovoltaic snow removal robot 100 can choose to activate either a snow removal mode or a dust removal mode depending on whether the snow thickness exceeds a preset snow thickness value. That is, if the snow thickness exceeds the preset value, the snow removal mode can be activated to perform snow removal operations. The snow removal component 30 of the photovoltaic snow removal robot 100 will then push the snow off the surface of the photovoltaic module 200. Figure 6 As shown; if the snow thickness is not greater than the preset snow thickness value, the dust removal mode can be activated, and the roller brush component 50 of the photovoltaic snow removal robot 100 can remove the loose snow on the surface of the photovoltaic module 200, such as... Figure 7 As shown. It should be noted that the above actions can be triggered by remote commands from the operator, or automatically triggered by the controller installed on the photovoltaic snow removal robot 100 after receiving a snowfall signal through the weather station interface. That is, when the controller receives the snowfall thickness value from the weather station, it can compare and analyze it with the preset snow accumulation thickness value, thereby automatically switching between snow removal mode and dust removal mode to carry out snow removal operations on the photovoltaic modules 200.
[0072] like Figure 6As shown, if the snow thickness exceeds a preset snow thickness value, the photovoltaic snow removal robot 100 activates its snow removal mode. The photovoltaic snow removal robot 100 can advance along a predetermined path of the photovoltaic array to push the snow away from the surface of the photovoltaic module 200 via the snow removal component 30, i.e., normal snow removal mode. Simultaneously, the controller acquires the operating status parameters of the photovoltaic snow removal robot 100 in real time. These operating status parameters may include at least one of the pressure value exerted on the snow removal component 30 during operation and the position change information of the photovoltaic snow removal robot 100, i.e., the displacement value of the photovoltaic snow removal robot 100 within a preset time. That is, the operating status parameters can be either one of the pressure value exerted on the snow removal component 30 during operation and the position change information of the photovoltaic snow removal robot 100 within a preset time, or a combination of both. Then, based on the operating status parameters, the snow removal component 30 can execute a preset snow-shaking action, or the photovoltaic snow removal robot 100 can execute an impact-pushing snow action to remove the accumulated snow. During the snow-shaking action, the snow removal component 30 performs multiple reciprocating lifting or flipping actions to loosen the snow, making it easier to remove. During the impact-pushing snow action, the photovoltaic snow removal robot 100 can apply an impact force to the snow, thereby pushing the snow away through the snow removal component 30. It should be noted that the pressure value experienced by the snow removal component 30 during operation can be monitored in real time by a pressure sensor. Simultaneously, the real-time location information of the photovoltaic snow removal robot 100 can be obtained through a global positioning system module.
[0073] Of course, the photovoltaic snow removal robot 100 can also compare the output torque of the drive motor that drives the photovoltaic snow removal robot 100 to the actual walking torque of the photovoltaic snow removal robot 100 to adopt different snow removal actions. When the output torque of the drive motor that drives the photovoltaic snow removal robot 100 is greater than the actual walking torque of the photovoltaic snow removal robot 100 and lasts for a certain period of time, such as 5 seconds, the snow on the surface of the photovoltaic module 200 can be removed by the snow removal component 30; when the output torque of the drive motor that drives the photovoltaic snow removal robot 100 is greater than the actual walking torque of the photovoltaic snow removal robot 100, but lasts for a short period of time, such as 1 second, or the output torque of the drive motor that drives the photovoltaic snow removal robot 100 is equal to the actual walking torque of the photovoltaic snow removal robot 100, the loose snow on the surface of the photovoltaic module 200 can be removed by the roller brush component 50 of the photovoltaic snow removal robot 100.
[0074] In some embodiments, when the operating state parameters meet a first preset condition, the snow removal component 30 performs the snow-shaking action; when the operating state parameters meet a second preset condition, the photovoltaic snow removal robot 100 can perform an impact snow-pushing action. Specifically, when the operating state parameters meet the first preset condition, that is, when the actual displacement value of the photovoltaic snow removal robot 100 within a preset time (e.g., 5 seconds) is less than a first displacement threshold (e.g., 0.1 meters), and the pressure value experienced by the snow removal component 30 during operation is greater than the first threshold (e.g., 50 Newtons) for a period of time (e.g., 2 seconds), this indicates that although the photovoltaic snow removal robot 100 is attempting to move forward, it is almost in a state of slipping or getting stuck. At this time, the controller of the photovoltaic snow removal robot 100 recognizes that it is obstructed by snow accumulation, and thus performs the preset snow-shaking action. During the snow-shaking action, the snow removal component 30 can perform multiple... The reciprocating lifting or flipping motions loosen the snow, allowing it to be pushed away from the surface of the photovoltaic module 200 by the snow removal component 30. When the operating parameters meet the second preset condition, i.e., the pressure value of the snow removal component 30 during operation is greater than the second threshold (e.g., 80 Newtons) for a period of time (e.g., 2 seconds), and the second threshold is greater than the first threshold, the controller of the photovoltaic snow removal robot 100 recognizes that it is obstructed by severe snow accumulation, such as very thick, compacted wet snow or a mixture of ice and snow, and executes the preset impact snow pushing action to scatter the snow or push it away from the surface of the photovoltaic module 200.
[0075] In some embodiments, the impact snow-pushing action can be achieved by the photovoltaic snow-sweeping robot 100 performing multiple back-and-forth movements to repeatedly impact the snow through the snow-clearing component 30, thereby achieving the effect of scattering the snow. Of course, the impact snow-pushing action can also be achieved by the photovoltaic snow-sweeping robot 100 first moving backward a preset distance (e.g., 1 meter) or for a preset time (e.g., 3 seconds), and then the photovoltaic snow-sweeping robot 100 accelerating forward to push the snow away from the surface of the photovoltaic component 200 through the inertia brought about by the acceleration.
[0076] In some embodiments, when the operating state parameters meet the second preset condition, during the process of the photovoltaic snow sweeping robot 100 performing the preset impact snow pushing action, the snow removal component 30 can perform the preset snow shaking action. That is, when the snow removal component 30 is embedded in the snow, the snow shaking action can be triggered. At this time, the snow removal component 30 can perform multiple reciprocating lifting or flipping actions to make the snow looser, so that the snow removal component 30 can push the snow away from the surface of the photovoltaic module 200.
[0077] The control method for the photovoltaic snow-sweeping robot 100 disclosed in this application involves acquiring at least one of the following operating state parameters: the pressure value of the snow-clearing component 30 of the photovoltaic snow-sweeping robot 100 during operation, the position change information of the photovoltaic snow-sweeping robot 100, and the current value of the drive motor that drives the photovoltaic snow-sweeping robot 100. If the operating state parameter meets a first preset condition, the snow-clearing component 30 performs a preset snow-shaking action. During the snow-shaking action, the snow-clearing component 30 performs multiple reciprocating lifting or flipping actions to loosen the snow and facilitate its removal. If the operating state parameter meets a second preset condition, the photovoltaic snow-sweeping robot 100 performs a preset impact snow-pushing action to push the snow through the snow-clearing component 30.
[0078] The control method for the photovoltaic snow-sweeping robot 100 disclosed in this application obtains the operating status parameters of the photovoltaic snow-sweeping robot 100, thereby switching between different snow removal modes, avoiding blindly increasing thrust, and reducing the load of a single push. Simultaneously, different snow removal methods can be switched for snow of varying thicknesses, effectively solving the problem of traditional robots easily getting stuck and interrupting operations in heavy snow or thick snow conditions, significantly improving the snow removal efficiency and reliability of the photovoltaic snow-sweeping robot 100.
[0079] In some embodiments, when the operating state parameters meet a third preset condition, i.e., when the operating state parameters meet at least one of the following conditions: the pressure value experienced by the snow removal component 30 during operation is greater than a third threshold (e.g., 100 Newtons) for a period of time (e.g., 2 seconds) and the displacement of the photovoltaic snow removal robot 100 within a preset time (e.g., 5 seconds) is less than a second displacement threshold (e.g., 0.05 meters), the controller can obtain the snow thickness, obtain the height stratification adjustment threshold of the snow removal component 30 based on the maximum snow removal thickness of the snow removal component 30 in historical snow removal data, and establish the snow thickness and height stratification adjustment threshold. The snow is layered based on a mapping relationship. During the snow removal component 30's layering process, the component can adjust the height layering threshold to clean the snow layer by layer from top to bottom. For example, if the maximum snow removal thickness of the snow removal component 30 is 8cm, then the height layering threshold is 8cm. If the thickness of the snow to be removed is 12cm, the snow can be divided into two equal layers of 6cm each, and the thickness of each layer after layering is no greater than 8cm. This reduces the number of layers required for snow removal, thereby reducing the number of times the snow is cleaned layer by layer and lowering the energy consumption of the photovoltaic snow removal robot 100. It should be noted that the third threshold can be greater than the second threshold, and the second displacement threshold can be less than the first displacement threshold.
[0080] In some embodiments, during the process of performing graded snow removal, the snow removal component 30 can first raise a first preset value and push the first layer of snow, i.e., the top layer of snow, and then the photovoltaic snow removal robot 100 returns and lowers the snow removal component 30 by the first preset value and pushes the second layer of snow, i.e., the bottom layer of snow, thereby pushing all the snow away from the photovoltaic component 200.
[0081] In some embodiments, when the pressure value of the snow removal component 30 during operation is greater than a third threshold and / or the displacement value of the photovoltaic snow removal robot 100 within a preset time is less than a second displacement threshold, the snow removal component 30 can raise the second preset value and push the first layer of snow, i.e., the top layer of snow. Then, the snow removal component 30 sequentially lowers the third preset value and the fourth preset value and respectively pushes the second layer of snow, i.e., the middle layer of snow, and the third layer of snow, i.e., the bottom layer of snow. That is, when the snow thickness is relatively thick, the snow layer can also be divided into three layers for graded pushing. After the snow removal component 30 raises the second preset value and pushes the first layer of snow forward, the photovoltaic snow removal robot 100 returns and lowers the snow removal component 30 by the third preset value to push the second layer of snow. Then, the photovoltaic snow removal robot 100 returns and lowers the snow removal component 30 by the fourth preset value to push the third layer of snow, thereby pushing all the snow away from the photovoltaic module 200. It should be noted that the second preset value can be greater than the first preset value.
[0082] In some embodiments, the photovoltaic snow removal robot 100 can directly raise the snow removal component 30 to a second preset value and push the first layer of snow according to the thickness of the snow. Then, the snow removal component 30 is lowered to a third preset value and a fourth preset value, respectively, and the second and third layers of snow are pushed. Of course, the photovoltaic snow removal robot 100 can also raise the snow removal component 30 to a fifth preset value and push the upper layer of snow. If the pressure value of the snow removal component 30 during operation is still greater than the third threshold and / or the displacement value of the photovoltaic snow removal robot 100 within a preset time is still less than the second displacement threshold, then the lifting distance is changed, and the snow removal component 30 is raised to a sixth preset value, thereby dividing the snow layer into three layers for graded pushing. After raising the sixth preset value, the top layer of snow is pushed forward, then the robot returns to push the middle layer of snow, and then the robot returns to push the bottom layer of snow.
[0083] It should be noted that, in the above embodiments, the lifting and lowering distances of the snow removal component 30 can be determined according to the actual working load of the photovoltaic snow removal robot 100, and the maximum lifting height of the snow removal component 30 must be less than the total thickness of each layer of snow.
[0084] In the above embodiments, when the operating status parameters meet the third preset condition, the snow removal component 30 can preferentially execute the preset graded snow removal action, that is, the photovoltaic snow removal robot 100 can only remove the snow by using a layered processing method.
[0085] In some embodiments, when the operating state parameters meet the third preset condition, the photovoltaic snow-sweeping robot 100 can first execute a preset impact snow-pushing action. When the snow-clearing component 30 penetrates the snow, it can trigger a snow-shaking action. At this time, the snow-clearing component 30 can perform multiple reciprocating lifting or flipping actions to loosen the snow further. Then, the snow-clearing component 30 can execute a preset graded snow-clearing action to push all the snow away from the photovoltaic module 200. Alternatively, the photovoltaic snow-sweeping robot 100 can first execute a preset snow-shaking action to loosen the snow further, and then the snow-clearing component 30 can execute a preset graded snow-clearing action to push all the snow away from the photovoltaic module 200.
[0086] In some embodiments, since a bridge is typically provided in the photovoltaic array to connect photovoltaic modules 200 at different locations, and the bridge may have combined working conditions such as height differences, misalignment, and deviation angles, there is a risk of abnormal jamming when the photovoltaic snow removal robot 100 passes through this scenario. Therefore, the control method may further include the steps of acquiring position information and passing through the bridge. In the step of acquiring position information, the photovoltaic snow removal robot 100 can obtain the relative positional relationship between itself and the bridge between the photovoltaic array in real time through a positioning component to prevent the snow removal component 30 from colliding with the bridge or jamming. When the distance between the photovoltaic snow removal robot 100 and the bridge between the photovoltaic array meets a preset distance threshold, the snow removal component 30 of the photovoltaic snow removal robot 100 can be raised to a non-working state, thereby safely passing through the bridge. It should be noted that the preset distance threshold can be a threshold greater than 0, that is, ensuring that the photovoltaic snow removal robot 100 raises the snow removal component 30 to a non-working state before reaching the bridge. In the non-working state, there is a preset height between the snow removal component 30 and the photovoltaic module 200, so that the snow removal component 30 is far away from the glass plate 201 of the photovoltaic module 200. The preset height can be determined according to the actual working conditions of the cable tray.
[0087] In some embodiments, the positioning component may employ a Global Positioning System (GPS) module to acquire the location information of the photovoltaic snow-sweeping robot 100, thereby raising the snow-clearing component 30 to a non-operating state before reaching the bridge. Alternatively, the positioning component may employ an RFID (Radio Frequency Identification) reader (a device that automatically identifies target objects and acquires data via radio waves) mounted on the photovoltaic snow-sweeping robot 100 in conjunction with a tag located on the bridge, thereby acquiring the arrival information of the photovoltaic snow-sweeping robot 100, enabling the photovoltaic snow-sweeping robot 100 to raise the snow-clearing component 30 to a non-operating state before reaching the bridge. Of course, the positioning component may also employ sensors such as proximity switches, ultrasonic sensors, and photoelectric switches, in conjunction with induction baffles or other similar triggers located near the bridge, to achieve location information identification of the bridge.
[0088] like Figure 1 As shown in the illustration, this application also discloses a photovoltaic snow removal robot 100, which may include a robot body 10, a walking component 20, a snow removal component 30, a power component 40, and a pressure detection element 311. The power component 40 drives the snow removal component 30 to perform lifting and / or flipping actions, enabling it to loosen the snow in the face of heavy snow or thick snow accumulation. This allows the snow removal component 30 to push the snow away from the surface of the photovoltaic component 200, thereby improving the snow removal efficiency and reliability of the photovoltaic snow removal robot 100. Simultaneously, the pressure detection element 311 on the snow removal component 30 can detect the pressure value applied by the snow, allowing the snow removal component 30 to perform corresponding snow removal actions based on the pressure value. This allows for switching between different snow removal methods for different snow thicknesses, effectively solving the problem of traditional robots easily getting stuck and interrupting operations in heavy or thick snow conditions, significantly improving the snow removal efficiency and reliability of the photovoltaic snow removal robot 100.
[0089] The following will combine Figures 1 to 21 The photovoltaic snow-sweeping robot 100 disclosed in the embodiments of this application will be explained and described in detail.
[0090] Among them, such as Figure 1 , Figure 2 and Figure 4 As shown, the robot body 10 serves as the load-bearing platform for the photovoltaic snow-sweeping robot 100 and may include a main beam 11, which may be made of a hollow steel tube with a rectangular cross-section. Furthermore, to improve the load-bearing capacity of the main beam 11, multiple stiffening ribs may be welded at intervals into the inner cavity of the main beam 11 to enhance its rigidity.
[0091] like Figure 1 and Figure 2 As shown, a roller brush assembly 50 can be provided below the robot body 10 to clean dust or snow from the surface of the photovoltaic module 200. The roller brush assembly 50 may include a roller brush drive, a roller brush shaft, and a roller brush mounted on the roller brush shaft. The roller brush can contact the surface of the photovoltaic module 200. The roller brush drive can be a drive motor, and the roller brush drive is connected to the roller brush shaft for transmission. Thus, the roller brush drive can drive the roller brush shaft to rotate, thereby driving the roller brush to rotate and cleaning the dust or snow from the surface of the photovoltaic module 200.
[0092] In some embodiments, the two ends of the roller brush shaft of the roller brush assembly 50 can be mounted below the main beam 11 by brackets. The brackets can be fixed brackets or adjustable brackets that can adjust the length, so that the tilt angle of the roller brush shaft can be adjusted by adjusting the brackets. This adjusts the pressure of the roller brush contacting the photovoltaic module 200, preventing damage to the glass plate 201 on the surface of the photovoltaic module 200 due to excessive pressure applied by the roller brush. At the same time, it can avoid cleaning blind spots caused by installation errors of the photovoltaic module 200, ensuring the stability and reliability of the cleaning by the photovoltaic snow sweeping robot 100.
[0093] like Figure 2 As shown, a self-charging photovoltaic module 60 and an electronic control module 70 can be respectively installed above the robot body 10, i.e. above the main beam 11. The self-charging photovoltaic module 60 provides a power source for the photovoltaic snow sweeping robot 100 to perform walking, snow sweeping, and dust sweeping actions. At the same time, the electronic control module 70 can be equipped with a controller that can control the photovoltaic snow sweeping robot 100 to perform walking, snow sweeping, and dust sweeping actions, so that the photovoltaic snow sweeping robot 100 can sweep away dust and snow on the surface of the photovoltaic module 200.
[0094] like Figures 1 to 4 As shown, the walking components 20 can be respectively set at both ends of the robot body 10, so that the robot body 10 can be driven by the walking components 20 to move on the photovoltaic components 200, so that the photovoltaic snow sweeping robot 100 can sweep each photovoltaic component 200 on the photovoltaic array.
[0095] In some embodiments, such as Figure 1 and Figure 4 As shown, to enhance the grip and stability of the photovoltaic snow-sweeping robot 100 on wet ski slopes or icy photovoltaic module 200 surfaces, the walking assembly 20 may include a walking track assembly 21, walking wheels 22, limit wheels 23, and a walking drive component 24. Among them, as... Figure 6 As shown, the walking track assembly 21 provides the main driving force and adhesion to effectively prevent the photovoltaic snow-sweeping robot 100 from slipping, while the walking wheels 22 provide auxiliary support, steering, or efficient movement on flat surfaces. The walking drive component 24 drives the walking track assembly 21 and the walking wheels 22 to rotate, allowing them to move on the surface of the photovoltaic module 200. Simultaneously, the limiting wheel 23 keeps the robot in close contact with the frame 202 of the photovoltaic module 200 to prevent the photovoltaic snow-sweeping robot 100 from detaching from the photovoltaic module 200 and falling. It should be noted that the walking drive component 24 can be a drive motor or other similar drive components.
[0096] In some embodiments, such as Figures 11 to 15As shown, the track assembly 21 may include a track drive wheel 211, a track driven wheel 212, a track 213, and a tensioning mechanism 214. The track 213 may be wound around the track drive wheel 211 and the track driven wheel 212 respectively. Figure 1 and Figure 11 As shown, two limit wheels 23 can be used, and the two limit wheels 23 can be respectively connected to the traveling wheel 22 and the track drive wheel 211 through right-angle transmission members 25. Simultaneously, the output shaft of the traveling drive member 24 can be respectively connected to the input shaft of the two right-angle transmission members 25 through transmission belts. Furthermore, as... Figure 11 As shown, the tensioning mechanism 214 can drive the track driven wheel 212 to move away from or towards the track drive wheel 211 to adjust the tension of the track 213, ensuring that the track 213 has a suitable tension, thereby improving the stability of the photovoltaic snow sweeping robot 100.
[0097] In some embodiments, such as Figure 11 As shown, the track assembly 21 may further include a mounting base 215 and a connector 216. Wherein, as Figure 17 As shown, the mounting base 215 may have a first mounting portion 2151 and a second mounting portion 2152, and the first mounting portion 2151 and the second mounting portion 2152 may be arranged perpendicular to each other, and as... Figure 11 As shown, the track drive wheel 211 can be mounted on the first mounting portion 2151 via the right-angle transmission member 25, and the track driven wheel 212 can be connected to the connecting member 216 for transmission, and the connecting member 216 is mounted on the first mounting portion 2151. Furthermore, as... Figure 16 and Figure 17 As shown, one of the connector 216 and the first mounting part 2151 may be provided with a horizontal adjustment hole 217, and the other may be provided with a fixing hole 218 that mates with the horizontal adjustment hole 217, i.e. Figure 16 As shown, multiple horizontal adjustment holes 217 can be provided on the connector 216, and as... Figure 17As shown, the first mounting part 2151 may be provided with a fixing hole 218 that cooperates with the horizontal adjustment hole 217, or the first mounting part 2151 may be provided with multiple horizontal adjustment holes 217, and the connector 216 may be provided with a fixing hole 218 that cooperates with the horizontal adjustment hole 217, so that the installation position of the connector 216 can be horizontally adjusted and locked and fixed by fasteners such as bolts. The tensioning mechanism 214 may include an adjusting screw 2141 that can pass through the second mounting part 2152. One end of the adjusting screw 2141 is connected to the connecting member 216. Locking nuts are respectively provided on both sides of the second mounting part 2152. The locking nuts are threadedly engaged with the adjusting screw 2141. By rotating the locking nuts, one end of the adjusting screw 2141 drives the connecting member 216 to move, thereby driving the track driven wheel 212 to move away from or towards the track drive wheel 211, so as to adjust the tension of the track 213 and ensure that the track 213 has a suitable tension, thereby improving the stability of the photovoltaic snow sweeping robot 100.
[0098] In some embodiments, such as Figure 18 As shown, the end of the adjusting screw 2141 near the connector 216 may be provided with a hook portion 2141a, and as... Figure 12 and Figure 16 As shown, the connector 216 may be provided with a locking hole 2161 that engages with the locking hook 2141a. The locking hook 2141a of the adjusting screw 2141 can be engaged in the locking hole 2161, and by rotating the locking nut, a tensile or thrust force can be applied to the connector 216 in the axial direction of the adjusting screw 2141 to ensure the stability of the tension of the track 213.
[0099] In some embodiments, such as Figure 18 As shown, a notch 2141b is symmetrically provided at the end of the adjusting screw 2141 near the connector 216, and the bottom wall of the notch 2141b is flat to better connect and fix the adjusting screw 2141 to the connector 216. Simultaneously, a hook portion 2141a is formed on the side of the notch 2141b near the connector 216. When connecting the adjusting screw 2141 and the connector 216, the hook portion 2141a can be engaged with the locking hole 2161 on the connector 216, and fasteners such as bolts can be passed through the notch 2141b and fixed to the connector 216. Furthermore, to tighten the bolts and other fasteners, a washer can be placed inside the notch 2141b, and the washer is fitted onto the bolts and other fasteners. The gasket has two opposing sides, and the two sides of the gasket are respectively fitted with the two opposing sides of the recess 2141b, thereby preventing the gasket from rotating synchronously with the bolts and other fasteners, so as to ensure the tightness of the bolts and other fasteners.
[0100] In some embodiments, such as Figures 11 to 13As shown, the track assembly 21 may further include a rotation limiting member 219, which has a U-shaped structure. Specifically, the rotation limiting member 219 consists of two cantilever plates and a cantilever connecting plate connecting the two cantilever plates. Each of the two cantilever plates has symmetrical rectangular openings, allowing them to engage with locking nuts on both sides of the second mounting portion 2152, thus preventing the locking nuts from rotating freely and ensuring the stability of the track tension adjustment. Simultaneously, the cantilever connecting plate can be fixed to the second mounting portion 2152 using bolts or other fasteners. The rotation limiting member 219 can be a one-piece structure or a separate structure formed by welding two cantilever plates and a cantilever connecting plate; this is not limited here.
[0101] In some embodiments, such as Figure 16 As shown, the connector 216 may include a fixed base 2162 and a driven shaft 2163 disposed on the fixed base 2162. Meanwhile, the first mounting portion 2151 of the mounting base 215 may be provided with a rectangular hole that matches the fixed base 2162, so that the driven shaft 2163 of the connector 216 can pass through the rectangular hole and be rotatably connected to the track driven wheel 212. In addition, a limiting plate 2164 can be provided on the fixed base 2162. The limiting plate 2164 can fit with the first mounting part 2151 to prevent the connector 216 from coming out of the rectangular hole. The connector 216 can move along the rectangular hole to adjust the installation position of the connector 216. At the same time, the horizontal adjustment hole 217 and the locking hole 2161 can be opened on the limiting plate 2164 so that the connector 216 and the first mounting part 2151 can be connected and fixed by fasteners such as bolts. The adjusting screw 2141 can be connected to the limiting plate 2164 to realize the connection and fixation between the adjusting screw 2141 and the connector 216.
[0102] In some embodiments, such as Figures 19 to 21 As shown, the right-angle transmission component 25 may include a housing 251, a drive shaft 252, a driven shaft 253, and a bevel gear 254. The drive shaft 252 and the driven shaft 253 may be arranged perpendicularly to each other, and each may be equipped with a bevel gear 254, allowing the drive shaft 252 and the driven shaft 253 to be connected via the bevel gear 254. The bevel gear 254 may be located inside the housing 251, while the drive shaft 252 may extend out of the housing 251. One end of the drive shaft 252 may be connected to a traveling wheel 22 or a track drive wheel 211, and the other end of the drive shaft 252 may be connected to the output shaft of the traveling drive component 24 via a transmission belt. Meanwhile, the driven shaft 253 can pass through the housing 251 and connect to the limiting wheel 23, so that the walking wheel 22, the track drive wheel 211 and the limiting wheel 23 can be driven to rotate simultaneously by a walking drive component 24, thereby simplifying the structure of the walking component 20 and meeting the lightweight requirements of the photovoltaic snow sweeping robot 100.
[0103] In some embodiments, such as Figure 19 As shown, the housing 251 can adopt an L-shaped structure, and multiple threaded holes are respectively provided on the two end faces of the housing 251. The threaded holes on the end face of the housing 251 that protrude from the drive shaft 252 can mate with the connecting holes on the first mounting part 2151 of the mounting base 215, so that the right-angle transmission component 25 can be fixed to the first mounting part 2151 of the mounting base 215 by fasteners such as bolts. Figure 12 As shown, a reinforcing member 220 may be provided between the right-angle transmission member 25 and the first mounting part 2151. The reinforcing member 220 may be a plate-shaped structure that has been bent multiple times, so that one end of the reinforcing member 220 can be fixed to the first mounting part 2151 of the mounting base 215 by fasteners such as bolts, and the other end of the reinforcing member 220 can be connected to the threaded hole on the end face of the driven shaft 253 of the housing 251 by fasteners such as bolts, thereby improving the connection strength between the right-angle transmission member 25 and the first mounting part 2151.
[0104] In some embodiments, such as Figure 1 As shown, back plates 12 can be fixed to both ends of the main beam 11. The walking track assembly 21 and the walking wheels 22 can be located on opposite sides of the two back plates 12. The walking drive component 24 can be located on the same side as the walking wheels 22. The output shaft of the walking drive component 24 and the drive shafts 252 of the two right-angle transmission components 25 can pass through the back plates 12 and be connected via a transmission belt on opposite sides of the two back plates 12. Simultaneously, the housings 251 of the two right-angle transmission components 25 can be fixed to the back plates 12 with bolts or other fasteners to achieve the connection and fixation between the walking assembly 20 and the robot body 10. Furthermore, a protective cover 13 can be installed on the opposite sides of the two back plates 12 to prevent dust and / or snow from interfering with the transmission between the output shaft of the walking drive component 24 and the drive shafts 252 of the two right-angle transmission components 25, thereby ensuring the stability of the photovoltaic snow-sweeping robot 100's movement.
[0105] like Figures 1 to 4 As shown, the snow removal component 30 and the power component 40 can both be mounted on the robot body 10, and the snow removal component 30 can be located in front of the roller brush component 50, so that during the movement of the photovoltaic snow removal robot 100, the snow removal component 30 can push the snow off the photovoltaic module 200, thereby achieving the effect of removing the snow from the photovoltaic module 200. Meanwhile, as... Figure 6 and Figure 7 As shown, the power component 40 can drive the snow removal component 30 to perform lifting and / or flipping actions, thereby loosening the snow through the snow removal component 30, making it easier to remove the snow from the photovoltaic module 200. In addition, it can realize the switching between the working state and the non-working state of the snow removal component 30 to ensure that the photovoltaic snow removal robot 100 can safely pass through the bridge.
[0106] In some embodiments, such as Figure 1 As shown, the snow removal assembly 30 may include a mounting beam 31 and at least one scraper assembly 32 mounted on the mounting beam 31. That is, one scraper assembly 32 may be used, or two or more may be arranged at intervals along the mounting beam 31. The mounting beam 31 is connected to the power assembly 40, so that the power assembly 40 can drive the snow removal assembly 30 to perform lifting and / or tilting actions.
[0107] In some embodiments, such as Figure 1 and Figure 5 As shown, the scraper assembly 32 may include a scraper 321 and a pressure plate 322. The scraper 321 is mounted on the mounting beam 31 via the pressure plate 322. That is, the scraper 321 can be fixed to the pressure plate 322 by fasteners such as bolts. At the same time, the pressure plate 322 can be mounted on the mounting beam 31, thereby realizing the connection between the scraper assembly 32 and the mounting beam 31.
[0108] In some embodiments, such as Figure 5 As shown, at least two scraper assemblies 32 can be arranged along the axial direction of the mounting beam 31, that is, two or more scraper assemblies 32 can be used, and each scraper assembly 32 can be arranged along the axial direction of the mounting beam 31. At the same time, two adjacent scraper assemblies 32 can rotate about their opposite ends, thereby adjusting the angle of the scraper assemblies 32 to adapt to the bending deformation of the photovoltaic module 200 in the flat single-axis scenario and prevent excessive compression of the photovoltaic module 200.
[0109] In some embodiments, such as Figure 5 As shown, two scraper assemblies 32 can be used, and the ends of the pressure plates 322 of the two scraper assemblies 32 that are far apart from each other are connected to the mounting beam 31 by a pin, so that the two scraper assemblies 32 can rotate around the ends that are far apart from each other. At the same time, one of the ends of the pressure plates 322 of the two scraper assemblies 32 that are close to each other and the mounting beam 31 can be provided with one or more vertical adjustment holes 3221, and the other can be provided with a threaded hole that matches the vertical adjustment hole 3221. That is, the vertical adjustment hole 3221 can be provided on the mounting beam 31 and the threaded hole can be provided on the pressure plate 322, or the vertical adjustment hole 3221 can be provided on the pressure plate 322 and the threaded hole can be provided on the mounting beam 31.
[0110] In some embodiments, such as Figure 5As shown, to facilitate the adjustment and fixing of the scraper assembly 32, the vertical adjustment hole 3221 can be provided on the pressure plate 322, and the threaded hole can be provided on the mounting beam 31. This provides a larger operating space for adjustment and fixing, thus facilitating the adjustment and fixing of the scraper assembly 32. After the angle of the scraper assembly 32 is adjusted, it can be connected by bolts or other fasteners through the vertical adjustment hole 3221 and threaded into the threaded hole from the side of the pressure plate 322 away from the mounting beam 31.
[0111] In some embodiments, to improve the connection reliability between the scraper assembly 32 and the mounting beam 31, such as Figure 5 As shown, one end of the pressure plate 322 of the two scraper assemblies 32, which is far apart from each other, and one end of the mounting beam 31 can be provided with an arc-shaped reinforcing hole 3222, while the other end is provided with a threaded hole that mates with the arc-shaped reinforcing hole 3222. That is, the arc-shaped reinforcing hole 3222 can be provided on the mounting beam 31, and the threaded hole is provided on the pressure plate 322; or the arc-shaped reinforcing hole 3222 can be provided on the pressure plate 322, and the threaded hole is provided on the mounting beam 31. This allows fasteners such as bolts to pass through the arc-shaped reinforcing hole 3222 and threadedly connect to the threaded hole, thereby improving the connection strength between the scraper assemblies 32 and the mounting beam 31, and thus improving the connection reliability between the scraper assemblies 32 and the mounting beam 31. It should be noted that, in order to ensure that the two scraper assemblies 32 can rotate around the pin shaft at their opposite ends, the arc-shaped reinforcing hole 3222 can be arranged around the pin shaft, so that the scraper assemblies 32 can rotate along the trajectory of the arc-shaped reinforcing hole 3222.
[0112] In the above embodiments, the angle adjustment of the scraper assembly 32 can be done manually, or a telescopic mechanism adapted to the scraper assembly 32 can be provided on the mounting beam 31. The movable ends of the two telescopic mechanisms are respectively connected to the close ends of the pressure plates 322 of the two scraper assemblies 32. Thus, the scraper assembly 32 can be rotated around the pin shaft by the telescopic movement of the telescopic mechanism to achieve the angle adjustment of the scraper assembly 32. Of course, a floating mechanism adapted to the scraper assembly 32 can also be provided on the mounting beam 31. The floating ends of the two floating mechanisms are respectively connected to the close ends of the pressure plates 322 of the two scraper assemblies 32. This allows the close ends of the two scraper assemblies 32 to float up and down according to the bending deformation of the photovoltaic module 200, thereby adapting to the bending deformation of the photovoltaic module 200 in the flat single-axis scenario and preventing excessive compression of the photovoltaic module 200. It should be noted that the floating mechanism may include a fixed part and a movable part with a cavity, and part of the movable part may be movably embedded in the inner cavity of the fixed part to form a deformable cavity. At the same time, a reset elastic element such as a spring may be provided in the deformable cavity. One end of the reset elastic element may be connected to the fixed part, and the other end of the reset elastic element may be connected to the movable part. The movable part is connected to the pressure plate 322 of the scraper assembly 32. Thus, through the elastic action of the reset elastic element, the scraper assembly 32 can achieve the effect of floating up and down according to the bending deformation of the photovoltaic module 200.
[0113] In some embodiments, such as Figure 8 As shown, the scraper 321 can be a toothed scraper, meaning the scraper 321 can include a snow-shoveling part 3211 and a connecting part 3212 arranged at an angle. The included angle between the snow-shoveling part 3211 and the connecting part 3212 can be 90°, 135°, 145°, etc. The connecting part 3212 can be installed on the mounting beam 31 via a pressure plate 322, meaning the connecting part 3212 can be fixed to the pressure plate 322 via bolts or other fasteners, and the pressure plate 322 is installed on the mounting beam 31. Simultaneously, the snow-shoveling part 3211 can have a toothed structure 3211a to better insert into the snow accumulation, loosen the snow, and thus push the snow away from the photovoltaic module 200.
[0114] In some embodiments, such as Figure 9As shown, the scraper strip 321 can also be a strip structure, and the scraper strip 321 may include a snow-scraping area 3213 and limiting areas 3214 located at both ends of the snow-scraping area 3213. The snow-scraping area 3213 can adhere to the surface of the glass plate 201 of the photovoltaic module 200, while the limiting areas 3214 can adhere to the outer side of the frame 202 of the photovoltaic module 200. A preset gap exists between the snow-scraping area 3213 and the limiting areas 3214 to accommodate the spacing between the glass plate 201 and the frame 202 of the photovoltaic module 200, ensuring that the snow-scraping area 3213 can better adhere to the glass plate 201 of the photovoltaic module 200, thus improving the snow-scraping effect. It should be noted that, in order to accommodate the spacing between the glass plate 201 and the frame 202 of the photovoltaic module 200, as... Figure 9 As shown, the scraper strip 321 can be cut along the cutting line 3215 at both ends so that the area between the snow scraping area 3213 and the limiting area 3214 can move, thereby ensuring that the snow scraping area 3213 can better fit the glass plate 201 of the photovoltaic module 200 and improve the snow removal effect.
[0115] In some embodiments, such as Figure 1 As shown, the power assembly 40 may include a connecting assembly 41 and a snow removal drive component 42. The snow removal assembly 30 can be movably connected to the main beam 11 of the robot body 10 via the connecting assembly 41, and the output end of the snow removal drive component 42 can be connected to the mounting beam 31 of the snow removal assembly 30, enabling the snow removal drive component 42 to drive the snow removal assembly 30 to perform lifting and / or tilting actions. It should be noted that the snow removal drive component 42 may employ an electric telescopic rod, a lead screw mechanism, a worm gear, etc.
[0116] In some embodiments, such as Figure 1 As shown, the connecting component 41 may include a connecting seat 411 and a flipping component 412. The connecting seat 411 can be installed on the main beam 11 of the robot body 10. One end of the flipping component 412 can be fixed to the mounting beam 31 of the snow removal component 30 by welding or bolting, and the other end of the flipping component 412 is hinged to the connecting seat 411 through a hinge axis, so that the snow removal drive component 42 can drive the snow removal component 30 to flip and lift around the hinge axis, thereby realizing the snow removal component 30's snow shaking action and switching between non-working states.
[0117] In some embodiments, such as Figure 10As shown, the connecting seat 411 includes an arc-shaped segment and connecting portions located at both ends of the arc-shaped segment. The two connecting portions are respectively connected to the main beam 11 of the robot body 10 and the flipping component 412. Simultaneously, a clearance space 4111 is formed below the arc-shaped segment to avoid interference with the roller brush assembly 50 when the snow removal component 30 performs a large-angle flipping motion. For ease of understanding, the connecting portion connected to the main beam 11 of the robot body 10 is defined as the first connecting portion, and the connecting portion connected to the flipping component 412 is defined as the second connecting portion. The first connecting portion may have multiple rows of holes 4115 arranged vertically, and the side of the main beam 11 has threaded holes adapted to the multiple rows of holes 4115. This allows the first connecting portion of the connecting seat 411 to be connected and fixed to the main beam 11 by bolts or other fasteners, and the installation position of the connecting seat 411 can be adjusted. Furthermore, symmetrical reinforcing parts 4114 are fixed on both sides of the first connecting part. The reinforcing parts 4114 can adopt an L-shaped plate structure or a rectangular plate structure, and multiple rows of holes 4115 can be provided on the reinforcing parts 4114 to be connected and fixed with the threaded holes on the side of the main beam 11 by bolts or other fasteners, thereby improving the connection strength between the connecting seat 411 and the main beam 11. The second connecting part is provided with a pivot hole 4112 for installing a hinge shaft, so that the flipping part 412 and the connecting seat 411 can be hinged by the hinge shaft. At the same time, the second connecting part can also be provided with a fan-shaped reinforcing hole 4113, and the fan-shaped reinforcing hole 4113 can be arranged around the pivot hole 4112. The flipping part 412 can be connected to the fan-shaped reinforcing hole 4113 by a pin, and the pin can move along the trajectory of the fan-shaped reinforcing hole 4113 to ensure the stability of the snow removal drive 42 driving the snow removal assembly 30 to flip and lift around the hinge shaft.
[0118] In the above embodiments, such as Figure 10 As shown, the connecting seat 411 can be composed of two symmetrically arranged sub-connecting plates, and the two sub-connecting plates are connected and fixed together by multiple connecting plates 4116. Of course, the connecting seat 411 can also adopt an integral structure and be provided with one or more connecting plates 4116 to improve the strength of the connecting seat 411, which is not limited here.
[0119] In some embodiments, such as Figure 1As shown, multiple pressure detection elements 311 can be used, and each pressure detection element 311 can be spaced apart on the mounting beam 31. Each pressure detection element 311 can include a pressure sensor and a trigger plate, allowing real-time monitoring of the pressure value experienced by the snow removal component 30 during operation. This enables the snow removal component 30 to perform corresponding snow removal actions based on the pressure value, allowing for switching between different snow removal methods for snow of varying thicknesses. This effectively solves the problem of traditional robots easily getting stuck and experiencing operational interruptions in heavy snow conditions, significantly improving the snow removal efficiency and reliability of the photovoltaic snow removal robot 100. It should be noted that the pressure detection element 311 can also be a strain gauge sensor, piezoelectric sensor, etc.
