Description
Technical Field
[0001] The present application relates to a dust cleaner suitable for the upper surface of a photovoltaic module, belonging to the technical field of photovoltaic power generation. Background Art
[0002] As a renewable and clean energy, solar photovoltaic has become an important force in today's global energy transformation. The surface of solar panels is prone to accumulation of sand, dust and other dirt. If not cleaned in a timely, scientific and professional manner, it can cause the power generation of the components to attenuate by up to 40%-60% and the power generation to drop by 20%-30%. Therefore, the concept of improving the power generation and efficiency of power stations by cleaning solar panels reasonably and scientifically and maintaining the components carefully has been recognized by the industry.
[0003] When building a photovoltaic array, if the gap between components is very small (such as spacing ≤ 10mm), ordinary dust auxiliary removal devices cannot be installed due to their large thickness. Or in some waterproof and heat-insulating photovoltaic systems (such as M-type aluminum-zinc-magnesium waterproof brackets or W-type aluminum alloy waterproof brackets, etc.), due to the bracket structure design and other reasons, the installation conditions of similar dust cleaners are mutually exclusive and cannot be installed.
[0004] Therefore, in order to solve the above technical problems, it is necessary to provide an innovative dust cleaner suitable for the upper surface of photovoltaic modules to overcome the above defects in the prior art. Utility Model Content
[0005] The utility model aims to provide an adjustable thin dust cleaner suitable for ultra-narrow spaces which does not need to be fixed with a photovoltaic component frame by buckles.
[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a dust cleaner suitable for the upper surface of a photovoltaic module, installed in the installation gap between photovoltaic modules, including a dust cleaner body, a plurality of water diversion grooves formed between the dust cleaner body and the photovoltaic module, a fixed spring piece abutting against the photovoltaic module is installed on the back of the dust cleaner body, the dust cleaner body includes a plurality of siphon contacts, the siphon contacts are located between two adjacent water diversion grooves, and the siphon contacts abut against the upper surface of the photovoltaic module.
[0007] By adopting the above technical scheme, when the ash cleaner body is inserted into the narrow gap formed between the photovoltaic modules, the fixed spring pieces can be deformed and abut against the photovoltaic modules, so that the ash cleaner body can be fixed to the photovoltaic modules, thereby eliminating the need to fix the ash cleaner body to the photovoltaic modules by snapping them into the frame of the photovoltaic modules. The ash cleaner body is also suitable for waterproof and heat-insulating photovoltaic systems, in which the siphon contact contacts the upper surface near the bottom edge of the frame of the photovoltaic module. When the rainwater fills the water diversion trough, the rainwater will flow out of the ash cleaner body along the water diversion trough under the action of the siphon, effectively reducing the thickness and accumulation surface of dust accumulation on the photovoltaic modules, extending the cleaning cycle of the photovoltaic modules, and reducing the number of cleanings, thereby reducing the cost of power station operation and maintenance and increasing the daily power generation of the photovoltaic modules.
[0008] The utility model is a ash cleaner suitable for the upper surface of a photovoltaic module, which is further configured as follows: an air hole penetrating the ash cleaner body is provided at the outer convex portion on the top of the ash cleaner body.
[0009] By adopting the above technical solution, rainwater can fall into the ash cleaner body through the air holes during heavy rain, and the inside of the ash cleaner body is backwashed once, thereby preventing the water diversion trough from being blocked due to internal dust drying.
[0010] The utility model is further configured as a dust cleaner suitable for the upper surface of a photovoltaic module: the number of the air holes is at least two.
[0011] By adopting the above technical solution, the amount of rainwater flowing into the ash cleaner body can be increased to improve the flushing efficiency.
[0012] The utility model is further configured as a dust cleaner suitable for the upper surface of a photovoltaic module: the number of the water diversion grooves is at least three groups.
[0013] By adopting the above technical solution, dust and rainwater on the surface of the photovoltaic module can be quickly discharged from the dust cleaner body.
[0014] The utility model provides a dust cleaner suitable for the upper surface of a photovoltaic module, which is further configured as follows: the dust cleaner body is made of elastic material.
[0015] By adopting the above technical solution, the siphon contact and the photovoltaic component can be abutted against each other, which improves the connection reliability and helps to achieve siphoning.
[0016] A dust cleaner suitable for the upper surface of a photovoltaic module of the utility model is further configured as follows: the siphon contact is inclined toward one side of the photovoltaic module, and its position does not exceed the edge of the battery cell inside the photovoltaic module; a water collecting chamber is formed between the dust cleaner body and the upper surface of the photovoltaic module, and the vertical height of the water collecting chamber is 1 mm to 5 mm.
[0017] By adopting the above technical solution, the water collecting chamber can collect rainwater. When the water collecting chamber is filled with rainwater, the rainwater seals the air holes and is discharged to the outside of the photovoltaic module by the rainwater's own gravity and the siphon principle.
[0018] The utility model provides a dust cleaner suitable for the upper surface of a photovoltaic module, which is further configured as follows: the dust cleaner body is in an "L" shape.
[0019] By adopting the above technical solution and adjusting the angle of the fixed spring piece, the dust cleaner body can be fixed between the installation gaps of the photovoltaic modules by using the fixed spring piece, and rainwater can flow out quickly.
[0020] The utility model is a dust cleaner suitable for the upper surface of a photovoltaic module, which is further configured as follows: a through slot is opened on the back of the dust cleaner body for facilitating the angle adjustment of a fixing spring piece, and the fixing spring piece and the through slot are in the same plane before the angle adjustment.
[0021] By adopting the above technical solution, the through groove provides a range for the movement of the fixed spring piece, so that the fixed spring piece can adjust the angle within the ash cleaner body. The width of the overall bottom of the utility model is the thickness of the ash cleaner body, and it can be inserted into the narrow gap between photovoltaic modules.
[0022] The utility model is further configured as a dust cleaner suitable for the upper surface of a photovoltaic module: the number of the fixed spring pieces is at least two.
[0023] The adoption of the above technical solution is conducive to fixing the dust collector body and the photovoltaic module.
[0024] Compared with the prior art, the utility model has the following beneficial effects:
[0025] 1. The fixing spring in the utility model fixes the device in the gap of the photovoltaic module, and there is no need to fix it with the frame of the photovoltaic module by buckles, and it is also suitable for waterproof and heat-insulating photovoltaic systems.
[0026] 2. The cooperation between the siphon contact and the water diversion trough in the utility model can effectively reduce the thickness and area of dust accumulation on the photovoltaic modules. Through the self-cleaning effect of rainwater, the cleaning cycle of the photovoltaic modules is extended and the number of cleaning times is reduced, thereby reducing the cost of power station operation and maintenance, increasing the daily power generation of photovoltaic modules, and saving labor costs and water. Because dust is removed in time, the hot spot effect of photovoltaic modules is avoided, which can extend the life of photovoltaic modules.
[0027] 3. The air holes in the utility model can allow rainwater to fall into the ash cleaner body through the air holes during heavy rain, and backwash the interior of the ash cleaner body to avoid blockages caused by internal dust drying.

[0034] Please refer to the instruction manual Figure 1 To Attachment Figure 3 As shown, the utility model is a dust cleaner suitable for the space above the photovoltaic module 8. The figure includes a dust cleaner body 1, which is installed in the gap between the photovoltaic modules 8 and the photovoltaic modules 8. As a preferred embodiment, the dust cleaner body 1 is in an "L" shape, which is convenient for the dust cleaner body 1 to be inserted into the gap between the photovoltaic modules 8 and the photovoltaic modules 8. The thickness of the material selected for the dust cleaner body 1 is 0.5mm to 2mm, so as to avoid the material being too thick to affect the device cost and does not affect the installation space.
[0035] A fixing spring piece 4 abutting against the photovoltaic module 8 is installed at the bottom of the cleaner body 1, and a through groove 6 is opened on the back of the cleaner body 1 to facilitate the movement of the fixing spring piece 4. Specifically, the fixing spring piece 4 is located on the back side of the cleaner body 1, and the fixing spring piece 4 can slide into the through groove 6. When the fixing spring piece 4 is located in the through groove 6, the width of the overall bottom of the utility model can be reduced, thereby facilitating the insertion of the cleaner body 1 into the gap between the photovoltaic module 8 and the photovoltaic module 8. Since the fixing spring piece 4 is made of elastic material, when the fixing spring piece 4 can be deformed to generate a force abutting against the photovoltaic module 8, the cleaner body 1 is fixed on the photovoltaic module 8. The number of fixing plates is at least two, which improves stability.
[0036] An air hole 5 penetrating the ash cleaner body 1 is provided at the convex portion on the top of the ash cleaner body 1. In heavy rain, rainwater can fall into the ash cleaner body 1 through the air hole 5 to backwash the inside of the ash cleaner body 1, thereby preventing the water diversion trough 2 from being blocked due to internal dust drying. As a preferred embodiment, the number of the air holes 5 is at least two, and different numbers of the air holes 5 can be set according to the diameter size, which can increase the amount of rainwater flowing into the ash cleaner body 1 to improve the flushing efficiency.
[0037] A number of water diversion grooves 2 are formed between the cleaner body 1 and the photovoltaic module 8. As a preferred embodiment, the number of the water diversion grooves 2 is at least three groups, and their width can be extended as needed, so that dust and rainwater on the upper surface of the photovoltaic module 8 can be quickly discharged from the cleaner body 1. The shape of the water diversion groove 2 can be set to different shapes such as semicircular curved surface, rectangle, body shape, etc., and its depth is maintained in the range of 1mm to 5mm.
[0038] The ash cleaner body 1 includes a plurality of siphon contacts 3, which are located between two adjacent water diversion grooves 2. The ash cleaner body 1 is made of elastic material, which enables the siphon contacts 3 to abut against the photovoltaic components 8, thereby improving the sealing performance. The shape of the air hole 5 is circular, and can also be other shapes such as triangle or rectangle.
[0039] Specifically, the siphon contact 3 contacts the upper surface near the lower edge of the frame of the photovoltaic module 8, and the siphon contact 3 is inclined to one side of the photovoltaic module 8, and the position does not exceed the edge of the battery sheet inside the photovoltaic module 8. A water collecting chamber 7 is formed between the dust collector body 1 and the upper surface of the photovoltaic module 8. The vertical height of the water collecting chamber 7 is 1mm to 5mm. The water collecting chamber 7 can receive rainwater. When the water collecting chamber 7 is filled with rainwater, the rainwater blocks the air hole 5, and the rainwater is discharged to the outside of the photovoltaic module 8 by its own gravity and the siphon principle. As a preferred embodiment, the angle formed between the siphon contact 3 and the photovoltaic module 8 is 30° or 45°, so as to extend the cleaning cycle of the photovoltaic module 8, reduce the number of cleaning times, reduce the cost of power station operation and maintenance, increase the daily power generation of the photovoltaic module 8, and save labor costs and water. Because dust is removed in time, the hot spot effect of the photovoltaic module 8 is avoided, which is also conducive to extending the life of the photovoltaic module 8.
[0040] The working principle of a dust cleaner suitable for the upper surface of a photovoltaic module of the utility model is as follows:
[0041] First, according to the width of the lowest edge of the photovoltaic module 8, 3 to 4 cleaner bodies 1 are inserted at intervals of 2m, and the fixed spring piece 4 is abutted against another photovoltaic module 8. The siphon contact 3 is in contact with the upper surface of the photovoltaic module 8, so that the upper surface of the cleaner body 1 is kept within an adjustable range of 1mm to 5mm from the upper surface of the photovoltaic module 8. When the photovoltaic module 8 is filled with rainwater and needs to be drained, the rainwater or other water sources mixed with dust are sucked to the upper surface of the cleaner body 1 through the siphon effect, and the rainwater is discharged to the outside of the cleaner body 1 by its own gravity, so as to achieve the purpose of cleaning the photovoltaic module 8 in an ultra-narrow space.
[0042] When the gap between photovoltaic modules 8 is large enough, the cleaner body 1 can also be made of non-metallic materials such as plastic, rubber, nylon, etc., and formed in one piece. At this time, the fixed spring piece 4 is at a fixed angle and can be fixed by the resilience of the non-metallic material.
[0043] The above specific implementation methods are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
