Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power station operation and maintenance, and in particular to a multifunctional operation and maintenance device for a new energy photovoltaic power station. Background Art

[0002] A photovoltaic power station is a photovoltaic power generation system that converts solar energy into electrical energy, connects to the power grid and transmits electricity to the grid. Photovoltaic panels are one of the most important components in a photovoltaic power station. They are a power generation device that generates direct current when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon).

[0003] Photovoltaic panels are generally set at an angle. In snowy winter weather, the photovoltaic panels will be covered with snow, which will block sunlight from shining on the photovoltaic panels, making it impossible for the photovoltaic panels to generate electricity. When too much snow accumulates, the weight of the snow may cause the photovoltaic panels to be crushed.

[0004] In the prior art, when there is a lot of snow on the photovoltaic panels, operation and maintenance personnel need to use tools such as rakes or shovels to push the snow off the photovoltaic panels. Large chunks of snow fall off, and the large friction between the snow and the photovoltaic panels may cause damage to the photovoltaic panels. After the snow is pushed down and cleared, some snow residue will remain on the photovoltaic panels, which needs to be wiped off manually with a rag. Due to the low temperature in winter, hot water may be sprayed to melt the snow residue before scrubbing. All of these will result in a lot of physical strength and time required to remove the snow.

[0067] A central shaft 22 is rotatably connected to the center of the central cylinder 21, and a spiral-shaped conveying blade 221 is fixedly connected to the central shaft 22;

[0068] The flip plate 23 and the outer sleeve of the central tube 21 are rotatably connected to a pair of rotating sleeves 231, and the front and rear rotating sleeves 231 are respectively in contact with the front and rear side walls of the cavity 11, and the rotating sleeves 231 are fixedly connected to the disks 232. The flip plate 23 is fixedly connected between the disks 232, and the flip plate 23 is evenly arranged around the axis of the central tube 21. The rotating sleeve 231 on the rear side is fixedly connected to a gear ring 233, and the rear side plate of the box body 1 is rotatably connected to a first rotating shaft 234, and the front end of the first rotating shaft 234 is fixedly connected to a spur gear 235 meshing with the gear ring 233;

[0069] as well as

[0070] The snow removal motor 24 is fixed to the outer wall of the first cover 13. The output shaft of the snow removal motor 24 is connected to the first rotating shaft 234 through a coupling. The first rotating shaft 234 and the central shaft 22 are fixedly connected with a first transmission wheel 241. The two first transmission wheels 241 are linked by a first belt 242.

[0071] The adjusting vehicle body is connected to the front side of the box body 1 and is used to adjust the height and tilt angle of the box body 1 and drive the box body 1 to move.

[0072] Preferably, a shovel seat 16 is fixedly connected to the bottom of the right side of the box body 1, the right side of the shovel seat 16 has the same inclination as the bottom of the first snow inlet 12, a guide seat 17 is fixedly connected to the shovel seat 16 front and back symmetrically, and a frame 18 is also fixedly connected to the left side of the shovel seat 16, and a roller 19 is connected to the frame 18 so as to rotate symmetrically left and right.

[0073] In this embodiment, Fig.16As shown, the height and angle of the box 1 are adjusted by adjusting the vehicle body so that the box 1 adapts to the installation height and angle of the photovoltaic panel 100. The roller 19 at the bottom of the box 1 is placed on the photovoltaic panel 100. The vehicle body is adjusted to drive the box 1 to move, thereby completely clearing the snow on the photovoltaic panel 100.

[0074] like Figure 3-Figure 4 As shown, when the snow removal motor 24 is working, it drives the first rotating shaft 234 and the spur gear 235 to rotate, so that the gear ring 233 rotates, and then the rotating sleeve 231, the disk 232 and the flip plate 23 rotate synchronously. The first rotating shaft 234 also drives the central shaft 22 and the conveying blade 221 to rotate through the first transmission wheel 241 and the first belt.

[0075] like Figure 5-Figure 7 As shown, the vehicle body is adjusted to drive the box body 1 to move from left to right on the photovoltaic panel 100, and the snow removal motor 24 drives the flip plate 23 to rotate clockwise (i.e. Figure 5 The shovel seat 16 shovels the snow on the photovoltaic panel 100, and the guide seat 17 allows the snow to enter the cavity 11 through the first snow inlet 12. The flip plate 23 drives the snow to move. When the space between the two adjacent flip plates 23 enters the upper part, the snow falls into the central tube 21 through the second snow inlet 211. The spiral direction of the conveying blade 221 is set so that the snow in the central tube 21 is conveyed from front to back when it rotates. The snow enters the first cover body 13 through the rear end of the central tube 21 and falls from the bottom of the first cover body 13, thereby realizing the gradual removal of the snow.

[0076] Example 2

[0077] Two groups of mounting tubes 110 are fixedly connected to the bottom of the box body 1 . The two groups of mounting tubes 110 are arranged alternately. A brush disc 111 is rotatably connected inside the mounting tube 110 . The lower surface of the brush disc 111 is densely covered with bristles 112 .

[0078] Preferably, the front side of the box body 1 is fixedly connected to a second cover body 113, a support plate 114 is fixedly connected to the second cover body 113, a hot air chamber 115 is formed below the support plate 114, a wind tube 116 is fixedly connected to the front side plate of the second cover body 113, the central shaft 22 is rotatably connected to the wind tube 116, the front end of the central shaft 22 extends into the wind tube 116 and is fixedly connected to the first fan blade group 117, and the left and right sides of the wind tube 116 are connected to the support plate 114 through a heating pipe 118. Then, a spiral heating wire 119 is sleeved on the heating tube 118, and a main air duct 120 is opened inside the box body 1 at the position corresponding to each group of mounting tubes 110. The front side of the main air duct 120 is connected to the hot air cavity 115, and the main air duct 120 is connected to the mounting tube 110 through an auxiliary air duct 121. A second fan blade group 122 is fixedly connected to the top of the brush plate 111, and the brush plate 111 is densely covered with through holes 123, and the through holes 123 and the bristles 112 are staggered with each other.

[0079] In this embodiment, after the accumulated snow is removed, some snow residues may still exist on the photovoltaic panel 100 . In this embodiment, the snow residues may be removed.

[0080] like Figure 3 and Figure 8 As shown, when the central shaft 22 rotates, it drives the first fan blade group 117 to rotate. The inclination direction of the first fan blade group 117 is set so that when the fan blade group rotates, air is sucked into the wind tube 116. The air in the wind tube 116 flows in the heating tube 118 and is heated by the heating wire 119. The heated air enters the hot air chamber 115.

[0081] like Figure 5 as well as Figure 12-13 As shown, hot air enters each mounting tube 110 through the main air duct 120 and the auxiliary air duct 121 , the hot air blows the second blade set 122 to drive the brush plate 111 and the bristles 112 to rotate, and the hot air is blown out through the through hole 123 .

[0082] When the box 1 moves, the accumulated snow on the photovoltaic panel 100 is cleared, but snow residues remain on the photovoltaic panel 100. The hot air blown out from the through hole 123 acts on the photovoltaic panel 100 to melt the snow residues, and the rotating bristles 112 brush the photovoltaic panel 100. On the one hand, the snow residues are moved, and part of the melted snow residues can slide down the inclined photovoltaic panel 100 after moving; on the other hand, the photovoltaic panel 100 can also be cleaned by brushing the bristles 112.

[0083] like Figure 2 As shown, the two groups of installation cylinders 110 are arranged alternately, and the bristles 112 on two adjacent brush plates 111 have overlapping areas in the longitudinal direction, so that the photovoltaic panel 100 can be fully brushed.

[0084] Example 3

[0085] A second rotating shaft 251 is evenly rotated longitudinally on the top of the box body 1, an elastic rod 252 is fixedly connected to the second rotating shaft 251, a third rotating shaft 253 is rotatably connected in the first cover body 13 above, a second transmission wheel 254 is fixedly connected to the third rotating shaft 253 and the first rotating shaft 234, the two second transmission wheels 254 are linked by a second belt 255, the third rotating shaft 253 and the second rotating shaft 251 are linked by a bevel gear pair 256, and an avoidance opening 257 is opened at the position corresponding to the second rotating shaft 251 on the flip plate 23, and the width of the avoidance opening 257 is greater than the diameter of the second rotating shaft 251.

[0086] Preferably, when viewed from the front to the rear, the snow removal motor 24 drives the flip plate 23 to rotate clockwise, and a baffle 258 is provided on the side of the flip plate 23 away from its rotation direction, and the baffle 258 corresponds to the avoidance opening 257 one by one. A mounting shaft 259 is fixedly connected to the baffle 258, and one side of the baffle 258 is plugged with the mounting shaft 259 through a plug hole. A torsion spring 2510 is sleeved on the mounting shaft 259, and the two ends of the torsion spring 2510 are respectively fixedly connected to the mounting shaft 259 and the inner wall of the plug hole, and the torsion spring 2510 provides a torque for the baffle 258 to be close to the flip plate 23;

[0087] A first rigid rod 2511 is fixed to the top of the cavity 11 . The first rigid rod 2511 is located on the left and right sides of the second rotating shaft 251 . A second rigid rod 2512 is fixed between the first rigid rods 2511 . The second rigid rod 2512 and the elastic rod 252 are staggered.

[0088] In this embodiment, when the space between the two flip plates 23 is rotated upward, the accumulated snow will generally fall into the central tube 21 through the second snow inlet 211, but the soft snow may be slightly agglomerated due to squeezing and thus cannot fall smoothly. This embodiment can solve the problem of the accumulated snow being unable to fall into the central tube 21 due to agglomeration.

[0089] like Figure 3 As shown, the first rotating shaft 234 drives the third rotating shaft 253 to rotate through the second transmission wheel 254 and the second belt 255, and the third rotating shaft 253 drives the second rotating shaft 251 and the elastic rod 252 to rotate through the bevel gear pair 256. When the elastic rod 252 rotates, the snow between the flip plates 23 can be disturbed to avoid the problem of snow being unable to fall due to agglomeration.

[0090] like Figure 3 as well as Figure 9-10 As shown, the baffle 258 is rotatably connected to the mounting shaft 259, and a torque is provided by the torsion spring 2510 to hold the flip plate 23 close. When the flip plate 23 moves to the top, the first rigid rod 2511 and the second rigid rod 2512 push the baffle 258 away, so that the second rotating shaft 251 and the elastic rod 252 pass through the avoidance opening 257. The setting of the first rigid rod 2511 and the second rigid rod 2512 can avoid bending caused by the contact force between the second rotating shaft 251 and the baffle 258, and protect the second rotating shaft 251. After the flip plate 23 passes the top, under the action of the torsion spring 2510, the baffle 258 is reset and the avoidance opening 257 is closed, so as to avoid leakage of the transported snow due to the existence of the avoidance opening 257.

[0098] as well as

[0099] The adjustment seat 36 is slidably connected to the guide rod 351 and meshes with the second screw rod 35. The rear side of the adjustment seat 36 and the box body 1 are fixedly connected with a second shaft rod 361, and a connecting rod 362 is evenly hinged between the two second shaft rods 362.

[0100] Preferably, a battery 371, a control switch 372 and a forward / reverse switch 373 are fixedly connected to the left side of the box body 1. The snow removal motor 24, the adjustment motor 324 and the heating wire 119 are powered by the battery 371. The control switch 372 is used to control the on / off circuit of the snow removal motor 24 and the heating wire 119. The adjustment motor 324 is a servo motor. The forward / reverse switch 373 is used to control the direction and start / stop of the adjustment motor 324.

[0101] In this embodiment, the technical features of adjusting the vehicle body are disclosed.

[0102] like Figure 16-Figure 19 As shown, when the shift seat 334 moves along the track rod 333, it can drive the drive sleeve 33 to move. After the shift seat 334 moves, the positioning screw 336 is screwed so that the bottom of the positioning screw 336 abuts against the bottom of the positioning groove 337, thereby fixing the positions of the shift seat 334 and the drive sleeve 33.

[0103] After the drive sleeve 33 moves, due to the presence of the ridge 323 and the groove 331 , and the drive sleeve 33 being rotatably connected to the shift seat 334 , the drive sleeve 33 can always rotate with the adjustment shaft 322 .

[0104] like Figure 14-15 As shown, when the driving sleeve 33 moves, it can drive the first active bevel gear 343 and the second active bevel gear 354 to move. When the adjustment motor 324 works, it drives the adjustment shaft 322 to rotate, and the driving sleeve 33 rotates with the adjustment shaft 322, and drives the first active bevel gear 343 and the second active bevel gear 354 to rotate.

[0105] When the first driving bevel gear 343 is meshed with the first driven bevel gear 342, the second driving bevel gear 354 is separated from the second driven bevel gear 353 (i.e. Fig.14 and Fig.15 The adjustment motor 324 can drive the first screw rod 34 to rotate.

[0106] When the shift seat 334 drives the driving sleeve 33 to move to the left, the first active bevel gear 343 can be separated from the first driven bevel gear 342. When the second active bevel gear 354 is engaged with the second driven bevel gear 353, the shift seat 334 and the driving sleeve 33 are fixed by the positioning screw 336. At this time, the adjustment motor 324 can drive the second screw 35 to rotate.

[0107] When the first screw rod 34 rotates, it is engaged in the threaded sleeve 341, and the adjustment box 32 is guided by the cooperation of the slide seat 321 and the slide rod 313 and cannot rotate. When the first screw rod 34 rotates, the height of the adjustment box 32 can be adjusted, and the adjustment box 32 drives the box body 1 to adjust the height. During this process, since the distance between the adjustment seat 36 and the adjustment box 32 remains unchanged, the inclination angle of the box body 1 will not change.

[0108] When the second screw 35 rotates, the adjustment seat 36 is guided by the guide rod 351, so that the distance between the adjustment seat 36 and the adjustment box 32 can be adjusted when the second screw 35 rotates. The adjustment seat 36 pulls the box body 1 through the connecting rod 362 to adjust the inclination angle of the box body 1.

[0109] That is, the height and the tilt angle of the box body 1 can be adjusted independently by moving the shift seat 334.

[0110] By adjusting the direction of the motor 324, the height and tilt angle of the box body 1 can be controlled.

[0111] like Fig. 20 As shown, the forward / reverse switch 373 , the adjustment motor 324 and the battery 371 form a current loop, the heating wire 119 and the snow removal motor 24 form a parallel loop, and the parallel loop, the control switch 372 and the battery 371 form a current loop.

[0112] The forward / reverse switch 373 can be used to control the direction of the motor 324 and the start / stop of the motor 324; the control switch 372 can be used to control the on / off of the circuits of the heating wire 119 and the snow removal motor 24.

[0113] The working principle of the present invention is:

[0114] First, the position of the shift seat 334 is moved so that the first active bevel gear 343 is meshed with the first driven bevel gear 342, and the direction of the adjustment motor 324 is controlled by the forward-reverse switch 373 to adjust the height of the box body 1; then, the position of the shift seat 334 is moved so that the second active bevel gear 354 is meshed with the second driven bevel gear 353, and the direction of the adjustment motor 324 is controlled by the forward-reverse switch 373 to adjust the inclination angle of the box body 1; after the adjustment is completed, the adjustment motor 324 is turned off, and the adjustment body is pushed so that the bottom of the roller 19 coincides with the upper surface of the photovoltaic panel 100, and the entire device is located on the left side of the photovoltaic panel 100.

[0115] The snow removal motor 24 and the heating wire 119 are started by controlling the switch 372, and the device is pushed to move from left to right.

[0116] The snow accumulated on the photovoltaic panel 100 enters the cavity 11 through the shovel seat 16 and the first snow inlet 12, and the flip plate 23 rotates to transport the snow. When it continues to be transported to the upper part, the snow is disturbed by the rotation of the elastic rod 252, so that the snow enters the central tube 21 through the second snow inlet 211, and the conveying blades 221 convey the snow in the central tube 21 from front to back. The snow falls from the rear end of the central tube 21 into the first cover body 13 and falls through the bottom of the first cover body 13.

[0117] During this process, the first fan blade group 117 rotates to draw air, the heating wire 119 heats the air, and the hot air enters the mounting tube 110 to blow the second fan blade group 122, thereby causing the brush plate 111 and the bristles 112 to rotate. The hot air is blown out from the through hole 123 and acts on the photovoltaic panel 100, melting the snow residue and brushing the photovoltaic panel 100 through the bristles 112.

[0118] The above steps can completely clear the snow on the photovoltaic panel 100 .
