Detailed Implementation

[0020] This embodiment describes an intelligent electrostatic dust removal device for the mirror surface of a solar collector, such as... Figure 1 , Figure 2 As shown, it includes: a main body 100, a negative ion releasing electrode plate 1 and an electrostatic adsorption plate 2 carrying a positive charge respectively installed in the main body 100. The negative ion releasing electrode plate 1 releases negative ions to the dust. A partition is provided in the main body 100 between the negative ion releasing electrode plate 1 and the electrostatic adsorption plate 2. The negative ion releasing electrode plate 1 and the electrostatic adsorption plate 2 are arranged in parallel, one in front of the other.

[0021] The negative ion releasing electrode plate 1 includes a substrate 11 and discharge tips 12 uniformly arranged on the substrate 11. The arrangement density of the discharge tips 12 on the substrate 11 is 80%-85%, and the discharge tips 12 are positioned facing the mirror surface. The substrate 11 is electrically connected to the power module. The electrostatic adsorption plate 2 includes an aluminum plate 21 with a thickness of 3-10 mm. Considering strength and weight, the thickness of the aluminum plate 21 is 5 mm. Adsorption holes 22 are uniformly opened on the surface of the aluminum plate 21. The pore diameter of the adsorption holes 22 is 3-5 mm, and the opening rate of the adsorption holes 22 on the aluminum plate 21 is 60%-80%. The aluminum plate 21 is electrically connected to the power module. The negative ion releasing electrode plate 1 uses an internal boost circuit to boost the voltage using diodes and capacitors for rectification and filtering. High corona discharge is generated through the tip DC discharge, thereby releasing a large number of electrons, which combine with dust on the mirror surface to form charged dust. Experiments were conducted on the specific structure of the negative ion releasing electrode plate 1 and the electrostatic adsorption plate 2 in this embodiment. Table 1 Table 2 Table 3 As can be seen from the test data in Tables 1-3, the optimal density of the discharge tip 12 on the substrate 11 is 85%, the preferred thickness is 5 mm, the preferred pore diameter of the adsorption hole 22 is 5 mm, and the optimal opening rate of the adsorption hole 22 on the aluminum plate 21 is 80%.

[0022] Walking components 5 are provided on both sides of the main body 100 to provide power for walking along the mirror surface. The walking components 5 adopt a motor-driven track structure, which is existing technology and will not be described in detail. In the forward direction, the negative ion releasing electrode plate 1 is arranged in front of the electrostatic adsorption plate 2. The negative ion wind generated by the negative ion releasing electrode plate 1 first acts on the dust.

[0023] A protective cover 103 is installed on the top of the main body 100. A photovoltaic panel 104 is mounted on the surface of the protective cover 103. A battery 105, a main control board, and a power module are installed inside the protective cover 103. The photovoltaic panel 104 is electrically connected to the battery 105 through a power charge / discharge management module. The battery 105 is electrically connected to the main control board and the power module through the power charge / discharge management module. The power module is electrically connected to the negative ion release electrode plate 1 and the electrostatic adsorption plate 2. An alarm and an imager are installed on the front surface of the main body 100 in the direction of movement. The alarm and imager are electrically connected to the main control board. The main control board is also communicatively connected to an automatic control module and a data acquisition module. The corresponding electrical control structure in this part is existing technology and will not be described in detail here.

[0024] like Figure 2 As shown, the main body 100 is equipped with two sets of electrostatic adsorption plates 2, each driven by a driving component 3. One set of electrostatic adsorption plates 2 is pushed out of the main body 100 by the driving component 3 to adsorb dust carrying negative ions, while the other set of electrostatic adsorption plates 2 is retracted into the main body 100 by the driving component 3 and cleaned by a cleaning component 4. A dust suction opening 101 is provided on the middle of the side of the main body 100 adjacent to the mirror surface. The two sets of electrostatic adsorption plates 2, the driving component 3, and the cleaning component 4 are symmetrically arranged in the main body 100 on both sides of the opening 101. The bottom of the main body 100 has a hollow structure, and a collection box 102 is provided below the main body 100. The dust suction opening 101 is between the two collection boxes 102. The collection box 102 is located directly below the electrostatic adsorption plates 2 when they are retracted into the main body 100. The collection box 102 is lined with an absorbent sponge.

[0025] like Figure 4 As shown, the driving component 3 is installed inside the main body 100 and is driven to connect with the electrostatic adsorption plate 2. The main body 100 is equipped with a cleaning component 4 that is linked to the driving component 3. The cleaning component 4 uses a brush for cleaning, combined with a micro-water flow to reduce dust. Water is stored in an absorbent sponge, effectively preventing water from spilling out of the collection box 102. Simultaneously, dust falling from the electrostatic adsorption plate 2 can be adsorbed onto the absorbent sponge. During linkage, the driving component 3 drives the electrostatic adsorption plate 2 to extend beyond the main body 100 and adsorb accumulated dust carrying negative ions, causing the cleaning component 4 to stop. When the driving component 3 drives the electrostatic adsorption plate 2 back into the main body 100, it activates the cleaning component 4 to clean the electrostatic adsorption plate 2.

[0026] likeFigures 4-6 As shown, the structure of the driving component 3 includes a guide frame 31, a slide 32, a crank 33, and a connecting rod 34. The slide 32 is slidably fitted within the guide frame 31. The electrostatic adsorption plate 2 is located within the guide frame 31 and fixedly connected to the slide 32. The crank 33 is rotatably mounted on the guide frame 31 and is connected to the motor for transmission. One end of the connecting rod 34 is hinged to the distal end of the crank 33, and the other end of the connecting rod 34 is hinged to the slide 32. The guide frame 31 is disposed within the main body 100 and cooperates with the second lifting assembly 8 to drive the electrostatic adsorption plate 2 to adjust its height up and down. When the crank 33 rotates, it pushes the slide 32 to slide within the guide frame 31 through the connecting rod 34, forming a crank-slider mechanism, thereby pushing the electrostatic adsorption plate 2 to the position of the dust suction opening 101, where the electrostatic adsorption plate 2 adsorbs accumulated dust.

[0027] like Figures 6-7 As shown, the specific linkage structure of the drive component 3 consists of a gear sector 35, a transmission gear set 36, a cam 37, and a linkage plate 38. The gear sector 35 is coaxially mounted on one side of the crank 33 and protrudes from the crank 33. The transmission gear set 36 is rotatably mounted on the guide frame 31 and drives the gear sector 35. The last gear of the transmission gear set 36 is connected to the cam 37 via a connecting shaft and rotates synchronously. The linkage plate 38 is slidably mounted on the guide frame 31 and is pushed by a spring and abuts against the wheel surface of the cam 37. The linkage plate 38 cooperates with the control valve 42 of the cleaning component 4. When the drive component 3 drives the electrostatic adsorption plate 2 to retract into the main body 100: the drive component 3 synchronously drives the control valve 42 to start; when the drive component 3 drives the electrostatic adsorption plate 2 to extend beyond the main body 100: the drive component 3 synchronously drives the control valve 42 to stop.

[0028] like Figure 7 As shown, taking the counterclockwise rotation of the crank as an example, when the crank 33 pulls the electrostatic adsorption plate 2 completely into the guide frame 31 through the connecting rod 34, it is in the initial position. The distribution angle of the gear sector 35 is 90°. One side of the gear sector 35 is close to the horizontal line passing through the center of the crank 33 but does not coincide with it. That is, in the initial state, the gear sector 35 is separated from the transmission gear set 36 and does not mesh, so the control valve 42 stops. The transmission gear set 36 is a spur gear transmission. The radius of the gear sector 35 is the largest. The transmission gear set 36 speeds up the transmission. When the gear sector 35 engages with the transmission gear set 36 and starts to drive, the electrostatic adsorption plate 2 has been partially pulled into the guide frame 31. At this time, the gear sector 35 drives the cam 37 to rotate through the transmission gear set 36. The protruding position of the cam 37 repeatedly squeezes the linkage plate 38, intermittently activating the water circuit. The spray pipe 43 sprays out dust-suppressing micro-water flow to form dust-suppressing water mist to prevent secondary diffusion of accumulated dust.

[0029] like Figure 4As shown, the cleaning component 4 includes a cleaning brush 44, a water tank 41, a control valve 42, and a spray pipe 43. The water tank 41 is installed inside the main body 100. The control valve 42 is activated by the linkage plate 38 to control the water flow. The control valve 42 is a valve with an automatic reset and stop function. The spray pipe 43 is arranged inside the main body 100 and close to the collection box 102, or it can be arranged in the collection box 102 and located directly below the electrostatic adsorption plate 2 when it is retracted into the main body 100. The water tank 41, the control valve 42, and the spray pipe 43 are connected by a pipeline. The main body 100 is located inside the electrostatic adsorption plate 2. Cleaning brushes 44 are provided above and below the plate 2. These brushes cooperate with the electrostatic adsorption plate 2. When the electrostatic adsorption plate 2 moves, such as when it retracts into the guide frame 31, or when the second lifting assembly 8 moves the plate up and down, the cleaning brushes 44 contact the plate. The brushes carry a neutral charge and clean the accumulated dust adsorbed on the surface of the plate. The dust falls into the collection box 102, where it is protected from secondary diffusion by the dust-reducing water mist. Figure 9 As shown, this embodiment also provides a more efficient arrangement of the cleaning brush 44. The cleaning brush 44 is specifically a cylindrical tube brush 47. The tube brush 47 is arranged along the length of the electrostatic adsorption plate 2, that is, perpendicular to its direction of movement. The guide frame 31 is provided with a bearing seat for mounting and connecting the end of the tube brush 47. The brush end of the tube brush 47 is in contact with the surface of the electrostatic adsorption plate 2. A rack 45 is slidably arranged on the guide frame 31 and is fixed and moves synchronously with the slide table 32. A roller 46 is coaxially fixed on the shaft end of the tube brush 47. The roller 46 meshes with the rack 45. At the same time, a baffle 48 is provided on the side of the tube brush 47. The tube brush 47 is located on the outwardly extending end of the guide frame 31. The slide table 32 drives the rack 45 to move synchronously, thereby driving the roller 46 and the tube brush 47 to rotate. While the electrostatic adsorption plate 2 moves, the tube brush 47 rotates and cleans the dust accumulated on the surface of the sweeper.

[0030] This embodiment also features a height-adjustable structure to ensure optimal working distance from the mirror surface, such as... Figure 2 , Figure 4As shown, the main body 100 is also provided with a first lifting component 7 for adjusting the distance between the negative ion releasing electrode plate 1 and the mirror surface, and a second lifting component 8 for adjusting the distance between the electrostatic adsorption plate 2 and the mirror surface. The first lifting component 7 and the second lifting component 8 are both set along the height of the main body 100 and fixed on the side wall of the main body 100. The first lifting component 7 and the second lifting component 8 are both lifting structures in the prior art. In this embodiment, the screw lifting mechanism in the prior art is adopted, which has the advantages of smooth lifting and good locking effect. The lifting slider of the second lifting component 8 is fixed with a lifting frame, the guide frame 31 is fixed on the lifting frame, and the driving component 3 drives the lifting through the second lifting component 8 to synchronously drive the electrostatic adsorption plate 2 to lift. Because the electrostatic adsorption plate 2 needs to be raised and lowered, the corresponding structure needs to be raised and lowered synchronously. Specifically, the collection box 102 is separated from the bottom of the main body 100. Except for the side adjacent to the dust suction opening 101, the other three sides of the collection box 102 are connected to the main body 100 through telescopic plates. The spray pipe 43 is installed inside the collection box 102. The water pipe of the cleaning component 4 is a water pipe with tensile and contractile elasticity. The control valve 42 is slidably fitted on the side wall of the main body 100 and cannot be rotated. It is implemented using a linear sliding guide pair in the prior art. The control valve 42 is installed on the slider, such as... Figure 7 As shown, the end of the linkage plate 38 is connected to the valve handle of the control valve 42. When the guide frame 31 is raised and lowered, it synchronously drives the control valve 42 to be raised and lowered. When the cam 37 pushes the linkage plate 38, the end of the linkage plate 38 squeezes the valve handle of the control valve 42 to control the water flow.

[0031] like Figure 2 As shown, a linkage lifting component 6 is also provided on the main body 100. The linkage lifting component 6 includes a main drive shaft 61, a first lifting screw 62, and a second lifting screw 63. The main drive shaft 61 is rotatably mounted on the side wall of the main body 100 along the length direction. The first lifting screw 62 and the second lifting screw 63 are both rotatably mounted on the side wall of the main body 100 along the height direction. The first lifting screw 62 and the second lifting screw 63 are respectively connected to the main drive shaft 61 through a right-angle transmission mechanism. The main drive shaft 61 is connected to a motor. In this embodiment, the right-angle transmission mechanism adopts a worm gear structure. Specifically, a worm gear is installed on the end of each screw, and a worm is coaxially arranged at the corresponding position of the main drive shaft 61 and the screw. The worm meshes with the worm gear to achieve transmission. Figure 4 As shown, a second slider 66 is threaded onto the second lifting screw 63. The second slider 66 slides linearly with the main body 100 and is fixedly connected to the side wall of the collection box 102 to drive the collection box 102 to rise and fall.

[0032] like Figure 3As shown, in the forward direction of the main body 100: a first lifting screw 62 is arranged in front of the second lifting screw 63. A first slider 64 is threaded onto the first lifting screw 62. The first slider 64 slides linearly with the main body 100. A probe 65 is provided on the first slider 64. A limiter is provided on the end of the probe 65 facing the mirror surface. A third lifting assembly 9 is provided on the side wall of the probe 65. An obstacle detection sensor 91 is installed on the third lifting assembly 9. The obstacle detection sensor 91 detects obstacles in front of the moving body. In this embodiment, linkage lifting components 6 are arranged on both sides of the main body 100, that is, probes 65 are designed on both sides of the main body 100. Obstacle detection sensors 91 are designed on the opposite surfaces of the two third lifting assemblies 9. The obstacle detection sensor 91 is an infrared beam sensor. The third lifting assembly 9 drives the obstacle detection sensor 91 to a preset height. When an obstacle blocks the infrared beam sensor, the sensor cannot receive the infrared signal feedback, thus realizing the function of obstacle detection.

[0033] When the main drive shaft 61 rotates, it synchronously drives the first lifting screw 62 and the second lifting screw 63 to rotate, causing the probe 65 and the two collection boxes 102 to descend synchronously until the limit switch detects that the mirror surface has reached the threshold and stops. The high synchronization between the collection box and the probe 65 ensures safety and improves efficiency.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
