Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic systems, and particularly relates to a snow removing device for a photovoltaic power generation panel. BACKGROUND

[0002] As a clean and renewable energy form, photovoltaic power generation has been widely used in recent years due to its environmental protection and economy. A photovoltaic system is formed by a plurality of photovoltaic cells connected in series or in parallel to form a large photovoltaic panel. The photovoltaic system converts solar energy into electrical energy through photovoltaic components and plays an important role in residential, commercial and industrial fields. However, in cold regions, snow will cover the surface of the photovoltaic components in winter, resulting in that the light cannot reach the panel, thereby greatly reducing the power generation or even causing the photovoltaic system to completely stop working. In order to ensure the normal operation of the photovoltaic system, the surface of the photovoltaic components needs to be cleaned regularly, and in areas where snow and ice cover for a long time, daily cleaning is required to ensure normal power supply and heating needs.

[0003] In order to solve the existing problems, the current common methods are manual snow removal and automatic mechanical device snow removal. The traditional manual snow removal method is time-consuming and labor-intensive, and the efficiency is low, which cannot meet the normal use requirements. When a mechanical scraper is used to automatically remove snow from the surface of the photovoltaic system, there are still some deficiencies. Snow will freeze into frost on the surface of the photovoltaic components, and after a period of time, thin ice will be formed, which is difficult to be removed by the mechanical scraper. In addition, since the area of the photovoltaic panel is large, when the entire panel surface is covered with a thin ice layer, the required force of the mechanical scraper will greatly increase, which not only may cause the automatic mechanical scraper to be unable to work or damaged, but also may cause mechanical stress to the surface of the photovoltaic components, thereby increasing the risk of damage to the photovoltaic system. SUMMARY

[0004] The present application provides a snow removing device for a photovoltaic power generation panel to solve the above technical problems.

[0005] To achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0006] A snow removing device for a photovoltaic power generation panel, comprising a photovoltaic component and a fixed support, the photovoltaic component is installed on the fixed support in an inclined manner, drive device housings are installed on both sides of the fixed support, a transmission assembly is arranged in the drive device housing, a sliding groove is arranged on the drive device housing and faces the photovoltaic component, the sliding groove is arranged in parallel with the panel surface of the photovoltaic component, a cleaning assembly is movably arranged on the surface of the photovoltaic component, first driving rods are arranged at both ends of the cleaning assembly, the first driving rods pass through the sliding groove and are connected with the transmission assembly, and a rotating assembly for controlling the rotation of the first driving rods is further arranged in the drive device housing.

[0007] The cleaning assembly comprises a shovel plate and a cleaning brush, the cleaning brush is sleeved on the first driving rod, the cleaning brush is fixed to the rear end of the shovel plate, a plurality of shovel strips are arranged on the front end surface of the shovel plate at equal intervals, a second driving rod is transversely arranged on the shovel strips, a plurality of ice breaking rollers are arranged on the second driving rod, and the ice breaking rollers are distributed at equal intervals between any two shovel strips, and the second driving rod is connected with the first driving rod through a synchronous belt transmission.

[0008] When the snow shoveling work is performed, the cleaning assembly is moved from the top to the bottom of the photovoltaic module to achieve ice breaking and snow removing. When the transmission assembly is started, the first driving rod moves downward along the plate surface of the photovoltaic module, and simultaneously rotates synchronously under the action of the rotating assembly. The first driving rod drives the rotation of the second driving rod through the synchronous belt, and the rotation of the second driving rod drives the rotation of the ice breaking roller, which can break the ice layer covering the surface of the photovoltaic module. Then the broken ice blocks and ice flakes are removed by the shovel plate and the shovel strips, and the ice blocks and ice flakes slide down along the inclined surface of the photovoltaic module, and then the broken ice slag, snow and the like are completely wiped off by the cleaning brush.

[0009] Further, the transmission assembly comprises a driving wheel, a driven wheel, a transmission belt and a first motor, the driving wheel is connected with the output end of the first motor, the driven wheel is installed on the inner wall of the driving device housing through a rotating shaft, the transmission belt is connected with the driving wheel and the driven wheel, a snap ring is arranged on the transmission belt, and the first driving rod is arranged on the snap ring and connected with the transmission belt for synchronous movement. The first motor is controlled to rotate by an external control system, thereby driving the rotation of the driving wheel and the transmission belt. The snap ring is arranged on the outer ring of the transmission belt, and the first driving rod can be driven to move along with the transmission belt during the movement of the transmission belt, so that the first driving rod moves along the sliding groove to realize the movement of the cleaning assembly.

[0010] Further, the rotating assembly comprises a rack and a rotating tooth, the rack is arranged on the inner side wall of the driving device housing, the first driving rod passes through the snap ring to connect the rotating tooth, and the rack and the rotating tooth are in meshing connection. The rack is fixedly installed on the side wall of the driving device housing, and the tooth portion faces downward, the rotating tooth is fixed to the free end of the first driving rod, and the meshing of the rotating tooth and the rack causes the self-rotation of the first driving rod during the movement of the first driving rod along the sliding groove, and then the rotation of the second driving rod, thereby realizing the rotation of the ice breaking roller. The rotation of the circumferential spikes of the ice breaking roller can break the ice surface.

[0011] Further, the lower end of the slope of the photovoltaic module is provided with a winding mechanism, the winding mechanism comprises a containing shell, a winding roller and a second motor, the winding roller is arranged in the containing shell and connected with the output end of the second motor, and the containing shell is fixedly connected with the front end of the fixed support. The winding mechanism adjusts the matrix net rope through the winding roller, cooperates with the cleaning assembly to realize fragmentation of the ice surface, breaks and cleans the fragmented ice, and further improves the cleaning effect and fragmentation effect.

[0012] Further, the winding roller is wound with a matrix net rope, and the free end of the matrix net rope is fixedly connected with the shovel strip. In the weather without light or at night, the matrix net rope is covered on the surface of the photovoltaic module, so that the rime generated in low-temperature weather forms a plurality of matrix shapes. When a plurality of small matrix ice blocks are adhered to the surface of the photovoltaic module, the adhesion is low, and the ice blocks can be pulled off the surface of the photovoltaic module when the matrix net rope moves. Residual ice blocks can be quickly removed through the action of the shovel strip and the shovel plate.

[0013] Further, the matrix gap of the matrix net rope corresponds to the cell plate assembly gap of the photovoltaic module, and a snow collecting groove is reserved between the containing shell and the fixed support. In the photovoltaic power generation process, the sun can only be focused above the photovoltaic cell to realize energy conversion, so when the matrix net rope is attached to the surface of the photovoltaic plate, the coverage of the matrix net rope is vertically aligned with the junction of the photovoltaic cell, which can ensure that the conversion efficiency of the photovoltaic module is not affected when it is lighted. In addition, the gap between the containing shell and the fixed support can ensure that the snow and ice residue brought down by the matrix net rope and the ice and snow cleaned by the cleaning assembly can slide down the surface of the photovoltaic module and fall into the snow collecting groove, avoiding affecting the work of the winding mechanism.

[0014] Further, the upper end of the slope of the fixed support is provided with a residence platform, and the top surface area of the residence platform is the same as the planar area of the cleaning assembly. The residence platform is used to provide a stable parking area during the non-working period of the cleaning assembly, which can not only avoid equipment wear or damage caused by long-term suspension of the cleaning assembly on the surface of the photovoltaic module, but also ensure the normal work of the photovoltaic module during the day without blocking and covering.

[0015] Further, the front end faces of the shovel plate and the shovel strip are both provided with inclined shovel angles. After the ice-breaking roller breaks the ice on the surface, the inclined shovel angle can more efficiently contact the ice and snow on the surface of the photovoltaic module, thereby reducing the contact resistance and facilitating smooth shoveling or scraping of the ice and snow blocks, and improving the cleaning efficiency.

[0016] Further, the bottom of the ice breaking roller is higher than the bottom surface of the shovel plate. During the rotation of the ice breaking roller, the ice breaking roller is always not in contact with the surface of the photovoltaic assembly, but has a small distance from the surface, which can ensure that the thin ice layer covering the surface of the photovoltaic assembly is broken and cleaned, and also can ensure that the ice breaking roller will not damage the photovoltaic assembly.

[0017] Further, the drive device housing is further provided with a containing groove accommodating the first motor, and the two first motors are connected with a wireless transmission unit through the control unit, and the second motor is connected with a wireless transmission unit through the control unit. The containing groove can protect the first motor from damage caused by external dust, rain, snow or ice residue, thereby improving the durability and reliability of the motor. The two first motors and the second motor are connected with a wireless transmission unit through the control unit, and the user issues an instruction signal to the control unit through a control terminal at a remote place, and the wireless transmission unit converts the signal into an appropriate wireless signal and transmits it to the corresponding motor. The two first motors and the second motor operate synchronously, and the motor decodes the signal through its own receiving module and performs corresponding actions. That is, during the downward movement of the cleaning assembly, the winding roller performs winding work, and during the upward movement of the cleaning assembly, the winding roller performs releasing work.

[0018] Compared with the prior art, the present application has the following beneficial effects:

[0019] 1. The cleaning assembly cooperates with the shovel plate, the cleaning brush and the ice breaking roller to efficiently remove the snow on the surface of the photovoltaic panel, and the movement of the transmission assembly drives the rotation of the rotating assembly, and then the ice breaking roller removes the thin ice layer formed by low temperature, thereby enhancing the ice layer cleaning ability and significantly improving the snow removal efficiency compared with the traditional mechanical scraper.

[0020] 2. According to the arrangement of the photovoltaic cells on the photovoltaic assembly, the matrix net rope is arranged on the surface of the photovoltaic panel, which divides the thin ice on the surface of the photovoltaic panel into several independent small ice blocks without affecting the photovoltaic lighting, especially for the thick ice layer formed at night, which not only facilitates the ice breaking effect of the ice breaking roller, but also facilitates the cleaning and scraping of the ice surface, thereby further improving the cleaning ability.

[0021] 3. The electric control cooperation of the transmission assembly, the rotating assembly and the winding mechanism realizes efficient and automatic snow removal on the surface of the photovoltaic panel without human operation and intervention, and ensures the safe use and high photoelectric efficiency of the photovoltaic panel.

The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0029] Example 1, as Figures 1-5 As shown, the present invention discloses a snow removal device for a photovoltaic panel, comprising a photovoltaic module 1 and a fixed bracket 2.

Specifically, when the snow shoveling work is performed, the cleaning assembly is moved from the upper direction to the lower direction of the photovoltaic module 1, so that the ice breaking and snow removing operations are realized. When the transmission assembly is started, the first driving rod 5 moves downward along the plate surface of the photovoltaic module 1, and simultaneously rotates synchronously under the action of the rotating assembly. The first driving rod 5 drives the rotation of the second driving rod 9 through the synchronous belt 11, the rotation of the second driving rod 9 drives the rotation of the ice breaking roller 10, and the ice layer covering the surface of the photovoltaic module 1 can be broken in this process. Then the broken ice blocks and ice flakes are shovelled away by the shovel plate 6 and the shovel strip 8, the ice blocks and ice flakes slide along the inclined surface of the photovoltaic module 1, and then the broken ice residues, snow and the like are completely wiped off by the cleaning brush 7.

[0031] The transmission assembly comprises a driving wheel 12, a driven wheel 13, a transmission belt 14 and a first motor 15, the driving wheel 12 is connected with the output end of the first motor 15, the driven wheel 13 is installed on the inner wall of the driving device housing 3 through a rotating shaft 16, the transmission belt 14 is in matched connection with the driving wheel 12 and the driven wheel 13, the transmission belt 14 is provided with a snap ring 17, and the first driving rod 5 is arranged on the snap ring 17 and is in synchronous movement connection with the transmission belt 14. Specifically, the first motor 15 is controlled to rotate by the control system outside, and then the rotation of the driving wheel 12 and the transmission belt 14 is driven. The snap ring 17 is arranged on the outer ring of the transmission belt 14, and the transmission belt 14 can drive the first driving rod 5 to move synchronously during the movement process, so that the first driving rod 5 moves along the sliding groove 4, and the movement operation of the cleaning assembly is realized.

[0032] The rotating assembly comprises a rack 18 and a rotating gear 19, the rack 18 is arranged on the inner side wall of the driving device housing 3, the first driving rod 5 passes through the snap ring 17 and connects the rotating gear 19, and the rack 18 and the rotating gear 19 are in meshing connection. Specifically, the rack 18 is fixedly installed on the side wall of the driving device housing 3, and the tooth part faces downward, the rotating gear 19 is fixedly connected to the free end of the first driving rod 5, the meshing of the rotating gear 19 and the rack 18 causes the self-rotation of the first driving rod 5 during the movement of the first driving rod 5 along the sliding groove 4, then the rotation of the second driving rod 9 is caused, and then the rotation of the ice breaking roller 10 can be realized. Through the rotation of the circumferential spikes of the ice breaking roller 10, the effect of breaking the ice surface is achieved.

[0033] The slope lower end of the photovoltaic module 1 is provided with a winding mechanism, the winding mechanism includes a containing shell 20, a winding roller 24 and a second motor 25, the winding roller 24 is arranged in the containing shell 20 and is connected with the output end of the second motor 25, and the containing shell 20 is fixedly connected with the front end of the fixed support 2. Specifically, the winding mechanism adjusts the matrix net rope 21 through the winding roller 24, and through cooperation with the cleaning assembly, the ice is fragmented, and the fragmentation is broken and cleaned, so that the cleaning effect and the fragmentation effect are further improved.

[0034] The matrix net rope 21 is wound on the winding roller 24, and the free end of the matrix net rope 21 is fixedly connected with the shovel strip 8. Specifically, in the weather without light or at night, the matrix net rope 21 is covered on the surface of the photovoltaic module 1, so that the rime generated in low-temperature weather forms a plurality of matrix shapes, and when a plurality of small matrix type ice blocks are adhered to the surface of the photovoltaic module 1, the adhesion is low, and when the matrix net rope 21 moves, the ice blocks can be pulled off the surface of the photovoltaic module 1. For the residual ice blocks, the shovel strip 8 and the shovel plate 6 can be used to quickly remove the ice blocks. Preferably, a crushing groove 26 is arranged at the inlet of the containing shell 20, and the opening of the crushing groove 26 is equal to the thickness of the matrix net rope 21. The ice pieces and ice residues adhered to the matrix net rope 21 are not conducive to the winding operation of the winding roller 24, and the ice blocks are crushed in the crushing groove 26 to ensure the normal operation of the winding roller 24.

[0035] The matrix gap of the matrix net rope 21 corresponds to the cell plate assembly gap of the photovoltaic module 1, and the containing shell 20 and the fixed support 2 are provided with a snow collecting groove 22 therebetween. Specifically, since the manufacturing difficulty and cost of a large photovoltaic panel are higher, and quality problems are prone to occur, the existing photovoltaic module is usually formed by assembling a plurality of small cell pieces in a matrix to form a large photovoltaic panel, so as to realize modular production and reduce production cost. In the photovoltaic power generation process, the sun can only be focused above the photovoltaic cell to realize energy conversion, so when the matrix net rope 21 is attached to the surface of the photovoltaic panel, the coverage surface of the matrix net rope 21 is vertically aligned with the junction of the photovoltaic cell, so as to ensure that the conversion efficiency of the photovoltaic module 1 is not affected when light is collected. In addition, the containing shell 20 and the fixed support 2 are provided with a gap therebetween, so that the snow and ice residues carried by the matrix net rope 21 and the ice and snow cleaned by the cleaning assembly can slide down along the panel surface of the photovoltaic module 1 and fall into the snow collecting groove 22, thereby avoiding affecting the work of the winding mechanism.

[0036] The slope upper end of the fixed support 2 is provided with a residence platform 23, the top surface area of the residence platform 23 is the same as the planar area of the cleaning assembly. Specifically, the residence platform 23 is used to provide a stable parking area during the non-working period of the cleaning assembly, which can not only avoid equipment wear or damage caused by long-term suspension of the cleaning assembly on the surface of the photovoltaic module 1, but also ensure the normal working of the photovoltaic module 1 during the day, without blocking and covering.

[0037] The front end surface of the shovel plate 6 and the shovel strip 8 is provided with an inclined shovel angle. Specifically, after the ice crushing roller 10 crushes the ice surface, the inclined shovel angle can more efficiently contact the ice and snow on the surface of the photovoltaic module 1, thereby reducing the contact resistance, facilitating smooth shoveling or scraping of the ice and snow block, and improving the cleaning efficiency.

[0038] The bottom horizontal height of the ice crushing roller 10 is higher than the bottom surface of the shovel plate 6. Specifically, during the rotation of the ice crushing roller 10, the ice crushing roller 10 is always not in contact with the surface of the photovoltaic module 1, but has a small distance from the surface, which can ensure the crushing and cleaning of the thin ice layer covering the surface of the photovoltaic module 1, and also can ensure that the ice crushing roller 10 will not damage the photovoltaic module 1.

[0039] The drive device housing 3 is also provided with a containing groove containing the first motor 15, and the two first motors 15 are connected with a wireless transmission unit through a control unit, and the second motor 25 is connected with a wireless transmission unit through a control unit. Specifically, the containing groove can protect the first motor 15 from damage caused by external dust, rain, snow or ice residue, thereby improving the durability and reliability of the motor. The two first motors 15 and the second motor 25 are connected with a wireless transmission unit through a control unit, and the user remotely issues an instruction signal to the control unit through a control terminal, and the wireless transmission unit converts the signal into an appropriate wireless signal and transmits it to the corresponding motor. The two first motors 15 and the second motor 25 operate synchronously, and the motor decodes the signal through its own receiving module and performs the corresponding action. That is, during the downward movement of the cleaning assembly, the winding drum 24 performs the winding operation, and during the upward movement of the cleaning assembly, the winding drum 24 performs the release operation.

[0040] In example two, on the basis of example one, a specific working principle of the snow removal device of the photovoltaic power generation panel is proposed.

[0041] The specific implementation principle process is as follows:

[0042] Firstly, according to the thickness of the ice and snow, the cleaning mode (light cleaning / deep ice breaking) is selected, the moving speed of the cleaning assembly, the rotating speed of the ice breaking roller 10 and the running parameters of the winding roller 24 are set on the control terminal, and the cleaning assembly is located at the upper end of the photovoltaic module 1. Then the movement of the cleaning assembly is started, the first motor 15 drives the driving wheel 12 to rotate, and the driven wheel 13 is driven to run through the transmission belt 14. The first driving rod 5 is synchronously moved downward along the sliding groove 4 by the clamping ring 17. The rotation of the first driving rod 5 is realized by the meshing of the gear teeth 19 and the rack 18, the rotation of the second driving rod 9 is driven by the first driving rod 5 through the synchronous belt 11, and the ice breaking roller 10 breaks the ice layer on the surface of the photovoltaic module 1 through the contact of the circumferential spikes. At the same time, the movement of the first driving rod 5 makes the shovel plate 6 and the shovel strip 8 shovel the broken ice and snow. Then the cleaning brush 7 wipes the surface of the photovoltaic module 1 to remove the residual ice and snow.

[0043] According to the local ice and snow coverage, the winding mechanism can be selected to be assembled. On the equipment equipped with the winding mechanism, the matrix net rope 21 is connected with the shovel strip 8 in advance. The first motor 15 and the second motor 25 are started synchronously, the winding roller 24 rotates to pull the matrix net rope 21 to move on the surface of the photovoltaic module 1. The matrix net rope 21 pulls the ice blocks formed on the surface of the photovoltaic module 1 to slide off, and assists the shovel plate 6 and the shovel strip 8 to complete the cleaning. The cleaned ice and snow and debris slide into the snow collecting groove 22 at the lower end of the photovoltaic module 1. After the winding and cleaning work is completed, the cleaning assembly returns to the residence platform 23 to complete a single snow removal work.

[0044] The first motor 15 is a bidirectional direct current motor, the current direction of the coil inside the motor changes the rotating direction of the motor, and the first motor 15 reversely rotates in the process of returning the cleaning assembly to the residence platform 23. In this process, the clamping ring 17 moves upward along the transmission belt 14, and then drives the first driving rod 9 to move upward, the gear teeth 19 reversely rotate to drive the ice breaking roller 10 to reversely rotate. Since the thin ice and snow on the surface have been removed in the process of the downward movement of the cleaning assembly, the cleaning assembly returns to the residence platform 23 mainly for the next cleaning work. In the returning process, the cleaning brush 7 can perform the wiping and cleaning work again. It should be noted that the time of the forward rotation of the first motor 15 corresponds to the movement of the cleaning assembly from the residence platform 23 to the inclined surface of the photovoltaic module 1, after the cleaning assembly reaches the bottom, the control unit controls the reverse rotation of the first motor 15, and the first motor 15 stops working until the cleaning assembly just reaches the residence platform 23, and a single control program is completed.

[0045] Of course, the present application can have other various embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present application without departing from the spirit and essence of the present application, but these corresponding changes and modifications should belong to the protection scope of the claims attached to the present application.
