DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figure 1-10 As shown, an automatic cleaning device for photovoltaic panel operation and maintenance, such as Figure 1-5 As shown, it includes a mounting frame 1 arranged on the photovoltaic panel 2; a cleaning mechanism 3 is arranged on the mounting frame 1, and a first driving mechanism 4 for driving the mounting frame 1 to slide along the surface of the photovoltaic panel 2 is arranged on the photovoltaic panel 2; the cleaning mechanism 3 includes: a circulation cleaning mechanism 31, the circulation cleaning mechanism 31 is installed on the mounting frame 1, when the first driving mechanism 4 drives the mounting frame 1 to slide along the surface of the photovoltaic panel 2, the circulation cleaning mechanism 31 is used to clean the photovoltaic panel 2; and a first auxiliary cleaning mechanism 32, the first auxiliary cleaning mechanism 32 includes an air pump 321 and an air gathering shell 322; the air pump 321 and the air gathering shell 322 are both installed on the mounting frame 1, the output end of the air pump 321 is connected to the inside of the air gathering shell 322, and the air outlet 324 of the air gathering shell 322 is arranged close to the gap between the circulation cleaning mechanism 31 and the photovoltaic panel 2, and the gap is the closest distance between the circulation cleaning mechanism 31 and the photovoltaic panel 2.

[0039] It should be noted that when cleaning the snow on the photovoltaic panel 2, the mounting frame 1 is driven by the first driving mechanism 4 to move along the surface of the photovoltaic panel 2, and the surface of the photovoltaic panel 2 is cleaned by the circulating cleaning mechanism 31. At this time, the air pump 321 is used to blow air into the wind gathering shell 322, so that the airflow accumulates in the wind gathering shell 322 and is then discharged from the air outlet 324, so that the airflow passes through the gap between the circulating cleaning mechanism 31 and the photovoltaic panel 2 and is discharged; the condensed ice layer and snow balls on the photovoltaic panel 2 are cleaned by the wind force of the airflow, so that they are quickly separated from the photovoltaic panel 2, thereby achieving the purpose of fast and efficient cleaning; at the same time, the sticky snow particles and other debris on the circulating cleaning mechanism 31 are cleaned by the wind force, thereby ensuring the continuous cleaning effect of the circulating cleaning mechanism 31.

[0040] like Figure 5 As shown, the interior of the wind gathering shell 322 is provided with an air guide portion 323 with an arc-shaped curved structure; the air guide portion 323 is used to allow the wind force in the wind gathering shell 322 to accumulate to a certain degree and then be discharged through the air outlet 324; it should be noted that, through the provision of the arc-shaped curved air guide portion 323 in the wind gathering shell 322, the wind introduced into the wind gathering shell 322 is accumulated in the wind gathering shell 322 and then discharged through the air outlet 324, which can enhance the discharged wind force, speed up the flow rate of the discharged wind, and improve the cleaning effect.

[0041] like Figure 1-5 As shown, the circulating cleaning mechanism 31 includes a belt 312, a first motor 313 and at least two rotating wheels 311; the at least two rotating wheels 311 are rotatably connected to the mounting frame 1, and the axes of the at least two rotating wheels 311 are parallel to the surface of the photovoltaic panel 2, the belt 312 is tensioned on the at least two rotating wheels 311, the first motor 313 is installed on the mounting frame 1, and the output end of the first motor 313 is coaxially connected to one of the rotating wheels 311; a fluff brush for cleaning debris on the surface of the photovoltaic panel 2 is provided on the belt 312; the fluff brush is a prior art, which is not shown in the figure and will not be described in detail.

[0042] It should be noted that when the first driving mechanism 4 drives the mounting frame 1 to move along the photovoltaic panel 2, one of the rotating wheels 311 is driven to rotate by the first motor 313, and then the belt 312 is driven to transmit with the cooperation of the remaining rotating wheels 311, and then the fluff brush on the belt 312 is driven to transmit, and the snow on the photovoltaic panel 2 is cleaned by the fluff brush; by driving the fluff brush to transmit in a circular manner, the purpose of continuously cleaning the snow on the photovoltaic panel 2 can be achieved; at the same time, the wind force formed by the first auxiliary cleaning mechanism 32 blows on the fluff brush, so as to achieve the cleaning work of the fluff brush and ensure its cleaning effect.

[0043] like Figure 1-5As shown, there are three rotating wheels 311; the bottom position of the belt 312 is tightened into a structure parallel to the surface of the photovoltaic panel 2 by the three rotating wheels 311, so as to increase the number of fluff brushes that are in contact with the photovoltaic panel 2 at the same time; it should be noted that, by the coordinated use of the three rotating wheels 311, the number of fluff brushes that are in contact with the surface of the photovoltaic panel 2 at the same time is increased, thereby improving the cleaning effect of the photovoltaic panel 2.

[0044] like Figure 1-6 As shown, the cleaning mechanism 3 also includes a second auxiliary cleaning mechanism 33, which includes a scraper 331 and a linkage mechanism 332; the scraper 331 is rotatably connected to the mounting frame 1; the linkage mechanism 332 is arranged between the mounting frame 1 and the scraper 331; when the wind pressure in the linkage mechanism 332 changes, the linkage mechanism 332 is used to drive the scraper 331 to rotate.

[0045] It should be noted that when the snow on the photovoltaic panel 2 is small and no ice layer is formed, it is convenient to remove the snow. At this time, the scraper 331 is kept (such as Figure 6 The cleaning portion of the scraper 331 is close to the belt 312, so that the fluff brush on the belt 312 can be cleaned; at the same time, the upwardly inclined belt 312 forms a baffle structure, which can prevent the snow from accumulating over the cleaning mechanism 3 as the mounting frame 1 moves when cleaning the snow, causing the snow to fall off the photovoltaic panel 2 after being cleaned by the cleaning mechanism 3, thereby improving the cleaning effect;

[0046] When the photovoltaic panel 2 has a lot of snow or ice that is difficult to remove, the first auxiliary cleaning mechanism 32 is activated to form a faster airflow at the gap between the bottom of the belt 312 and the photovoltaic panel 2, and the airflow assists in cleaning the snow and blows off the ice (such as Figure 5 As shown in the figure, when the airflow passes through the bottom of the belt 312, the belt 312 is guided by the rotating wheel 311 to be transmitted upward, and part of the airflow moves obliquely upward, that is, an oblique upward thrust is applied to the snow and ice layer, thereby lifting the ice layer upward, so as to achieve the purpose of quickly clearing the ice layer;

[0047] At the same time, as the wind pressure in the wind gathering shell 322 increases, the linkage mechanism 332 is driven to move, and then the scraper 331 is driven to rotate downward through the linkage mechanism 332, so that the wind force change can be controlled, and then the scraper 331 is driven to swing up and down, so that the snow intercepted by the scraper 331 can be thrown farther away, so as to reduce the pressure of clearing the snow, reduce the pressure of the snow on the ice layer on the ice layer, and improve the efficiency of clearing the snow and ice layer;

[0048] When the wind force increases to a certain extent, the scraper 331 can be driven to maintain a stable state of rotating downward (i.e. Figure 4When the airflow separates from the belt 312, it is blocked by the downwardly inclined scraper 331, so that most of the airflow can only be directed obliquely upward from the gap between the cleaning portion of the scraper 331 and the belt 312, that is, the wind force directed obliquely upward is increased, which makes it easier to lift the ice layer and improve the cleaning effect of the ice layer.

[0049] like Figure 7-10 As shown, the linkage mechanism 332 includes a pair of rotating shafts 3321, a mounting block 3323, a slider 3324, a piston 3325 and an elastic telescopic airbag 3326; the pair of rotating shafts 3321 are arranged on the scraper 331, the scraper 331 is rotatably connected to the mounting frame 1 through the rotating shafts 3321, the mounting block 3323 is sleeved on the rotating shaft 3321, the slider 3324 is arranged on the mounting block 3323, the rotating shaft 3321 is provided with an arc groove 3322, and the slider 3324 is slidably connected to the arc groove 3322; the mounting frame 1 is provided with a through hole, an elastic telescopic airbag 3326 is arranged on the mounting frame 1, the elastic telescopic airbag 3326 is communicated with the interior of the linkage mechanism 332 through the through hole, the elastic telescopic airbag 3326 is connected to the mounting block 3323, the piston 3325 is slidably connected to the through hole, and one end of the piston 3325 is connected to the elastic telescopic airbag 3326; a torsion spring 3327 is arranged between the rotating shaft 3321 and the mounting frame 1; when the scraper 331 loses its restriction, the torsion spring 3327 is used to drive the scraper 331 to rotate and reset.

[0050] It should be noted that as the wind pressure in the wind gathering shell 322 increases, the piston 3325 is pushed to move forward and away from the wind gathering shell 322, and the elastic telescopic airbag 3326 is extended by the piston 3325, while driving the mounting block 3323 to move, and then driving the slider 3324 to move, and under the restriction of the arc groove 3322, the scraper 331 is driven to rotate downward around the axis of the rotating shaft 3321; and when the wind force becomes smaller, the extended elastic telescopic airbag 3326 pushes the piston 3325 to move in the opposite direction and reset, and then drives the scraper 331 to swing upward and reset. In this way, by controlling the change of wind pressure in the wind gathering shell 322, the scraper 331 can be driven to swing up and down, and then the snow intercepted by the scraper 331 can be thrown out, so as to prevent excessive accumulation of snow and improve the efficiency of snow clearing.

[0051] like Figure 7-10 As shown, a rubber strip 3328 is provided on the scraper 331; the rubber strip 3328 is used to swing with the change of wind force to beat the photovoltaic panel 2 (such as Figure 1 shown).

[0052] It should be noted that when the wind pressure in the wind gathering shell 322 accumulates to a certain intensity, the scraper 331 can be pushed to rotate completely to a tilted downward state. At this time, the slider 3324 moves to the end of the arc groove 3322. When the wind pressure is maintained unchanged, the scraper 331 will remain in a tilted downward state. At this time, the flow rate of the derived air flow is faster. When the air flow passes through the rubber strip 3328, the rubber strip 3328 can be driven to swing by controlling the change of the air flow, so that the rubber strip 3328 continuously and lightly taps the ice layer on the photovoltaic panel 2, which can cause the ice layer to vibrate and fall off, thereby improving the cleaning effect.

[0053] like Figure 1-10 As shown, a heating tube for heating the air in the air gathering shell 322 is provided in the air gathering shell 322; the heating tube and the air pump 321 are connected to the controller through wires; it can be understood that the heating tube, wires and controller are all existing technologies, which are not drawn in the figure and will not be described in detail; thus, as the mounting frame 1 moves, the normal operation of the air pump 321 and the heating tube is not affected.

[0054] It should be noted that, through the setting of the heating tube, the derived air flow has a certain temperature. Since the heating tube is not in direct contact with the photovoltaic panel 2, the temperature rises within a certain gradient range, and no drastic temperature difference will occur to cause damage to the photovoltaic panel 2. The derived hot air flow can soften the rubber strip 3328 to a certain extent to prevent it from hardening in severe cold conditions and affecting its use.

[0055] like Figure 1-2 As shown, it can be understood that the present application does not limit the specific structure and installation method of the first drive mechanism 4, and only a feasible technical solution is provided below; the first drive mechanism 4 includes a second motor 41 and a screw 42; the second motor 41 is installed on the photovoltaic panel 2, the screw 42 is rotatably connected to the photovoltaic panel 2, and the output end of the second motor 41 is coaxially connected to the screw 42; the screw 42 is threadedly connected to the mounting frame 1.

[0056] It should be noted that the second motor 41 controls the rotation of the screw rod 42 , thereby driving the mounting frame 1 to move on the photovoltaic panel 2 , thereby driving the cleaning mechanism 3 to clean the photovoltaic panel 2 along the moving trajectory of the mounting frame 1 .

[0057] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction and a specific direction structure and operation, and therefore, cannot be understood as a limitation on the present invention. In addition, "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0058] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
