Description

Technical Field

[0001] This invention belongs to the field of dust removal technology for photovoltaic equipment, and specifically relates to a dust removal device for photovoltaic equipment. Background Technology

[0002] Photovoltaic equipment dust removal devices are systems specifically designed for cleaning the surfaces of solar panels. Their main function is to automatically and efficiently remove accumulated dust, sand, bird droppings, and other contaminants. In photovoltaic power generation systems, dirt on the surface of the panels significantly hinders light transmission, leading to a decrease in power generation efficiency; studies have shown that power losses can exceed 15% in severe cases. These devices ensure the photovoltaic system maintains optimal power generation performance by regularly maintaining the cleanliness of the panels. Currently, mainstream dust removal technologies include mechanical brushing, air blowing, and spraying. Mechanical methods use soft roller brushes to gently sweep away dust; air-cooled methods use airflow to disperse contaminants; and spraying methods use water flow for rinsing. More advanced solutions integrate intelligent monitoring technology, which can automatically start and stop cleaning operations based on environmental conditions and pollution levels, achieving precise and efficient operation and maintenance management. These devices not only improve power generation efficiency but also reduce manual cleaning costs, making them particularly suitable for large-scale photovoltaic power plants, water-scarce areas, and locations where installation is difficult to access. They are essential supporting equipment for maintaining the efficient operation of photovoltaic systems.

[0003] Existing photovoltaic equipment is usually installed in rows in desert areas, in large numbers and over a wide area. However, each time the solar panels are dusted, dust removal robots are usually used. Workers place the dust removal robots on the solar panels, and the robots move automatically to remove dust from the surface of the solar panels. Although this is more efficient than manual cleaning, because there are many solar panels in desert areas, after cleaning one row, it is still necessary to manually move the robots to clean the next row. The whole process requires manual monitoring, which increases labor costs. The transfer process also takes time, so the dust removal efficiency does not reach the optimal state. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dust removal device for photovoltaic equipment.

[0005] The technical solution adopted to solve the above technical problems is: a dust removal device for photovoltaic equipment, including a guide rail assembly, a moving mechanism installed on the guide rail assembly, and an air blowing mechanism installed at the central rear end of the moving mechanism; A roller brush mechanism is installed on the front end of the moving mechanism near the air blowing mechanism, and a dust sweeping mechanism is installed on the front end of the moving mechanism near the roller brush mechanism. A dust-collecting mechanism is installed at the top center of the moving mechanism, which can move on the fixed frame and remove dust from the solar panel assembly through a roller brush mechanism and a dust-sweeping mechanism.

[0006] Furthermore, the guide rail assembly includes a guide rail frame, on which a support frame is provided. Drive wheels are installed on one of the front and rear ends of the support frame, and driven wheels are installed on the other of the front and rear ends of the support frame. A first motor is installed on one of the front and rear ends of the support frame. One end of the output shaft of each of the two first motors is fixedly connected to the corresponding drive wheel. A mounting bracket is fixedly connected to the top of the support frame, and a brush is fixedly installed on the mounting bracket.

[0007] With the above technical solution, after dust removal from the first row of solar panel modules, when automatic dust removal is needed for the next row of solar panel modules, two first motors are started. Each motor drives the connected drive wheel to rotate through its output shaft. In conjunction with two driven wheels, the device moves along the guide rail frame, thus moving the entire device. When it reaches the fixed frame position on the next row of solar panel modules, the support frame stops moving. The moving mechanism automatically moves along the frame of the fixed frame on the next row, facilitating dust removal from the solar panel modules on the fixed frame. The entire process requires no manual operation by staff; the equipment moves automatically, greatly improving automation efficiency and saving labor costs. In addition, before cleaning the next row of solar panel modules each time, when the entire support frame is moved out, a brush can automatically remove dust from the surface of the solar panels on the moving mechanism, greatly improving the light absorption rate of the solar panels and ensuring that the guide rail assembly operates automatically at all times.

[0008] Furthermore, the moving mechanism includes a movable frame mounted on a support frame. The movable frame has slots and limiting holes on both sides. A solar panel is fixedly installed on one side of the top of the movable frame, and a storage box is fixedly installed on the other side of the top of the movable frame. An installation box is fixedly installed at the center of the top of the movable frame. First pulleys are installed at the four corners of the bottom of the movable frame. Two second pulleys are installed on the inner surfaces of both sides of the movable frame. First bevel gears are fixedly connected to the outer walls of the rollers of the two second pulleys. Second motors are installed at the front ends of both sides of the movable frame. Second bevel gears are fixedly connected to the outer walls of the output shafts of the two second motors. A stop is fixedly connected to the center of the movable frame.

[0009] With the above technical solution, when automatic dust removal of solar panel components is required, two second motors are started. Each motor drives the second bevel gear to rotate through its output shaft, which in turn drives the meshing first bevel gear to rotate, thereby driving the two second pulleys to rotate. In conjunction with multiple first pulleys, the movable frame can move at the edge of the fixed frame, thus facilitating dust removal of the solar panel components on the fixed frame. The solar panels can provide power for the entire device, and the dust cleaned from the solar panel components can be stored in a storage box for periodic cleaning.

[0010] Furthermore, each of the two first bevel gears meshes with a corresponding second bevel gear.

[0011] Through the above technical solution, the rotation of the first bevel gear drives the rotation of two second pulleys, which in turn causes the movable frame to move. This mechanism can move automatically, greatly improving the dust removal efficiency.

[0012] Furthermore, the air blowing mechanism includes multiple nozzles fixedly installed at the bottom of the rear end of the baffle, with a first connecting pipe fixedly connected between the multiple nozzles, a first air pump installed inside the mounting box, and a second connecting pipe fixedly connected between the first connecting pipe and the first air pump.

[0013] With the above technical solution, when cleaning the solar panel module, the first air pump is started, which draws in outside air through the upper air inlet valve, and then delivers the gas to multiple nozzles through the second connecting pipe and the first connecting pipe. The multiple nozzles blow air onto the surface of the solar panel module, thereby blowing away the attached dust and achieving preliminary cleaning. After blowing away a layer of attached dust, it is convenient for the subsequent dust removal by the roller brush mechanism.

[0014] Furthermore, the roller brush mechanism includes two first cylinders fixedly installed at the rear ends of both sides of the movable frame. The front ends of the pistons of the two first cylinders are fixedly connected to a first connecting frame. A roller brush cylinder is rotatably connected between the two first connecting frames. A third bevel gear is fixedly connected to one end of the outer wall of the rotating shaft of the roller brush cylinder. A third motor is fixedly installed on the top of one of the first connecting frames. A fourth bevel gear is fixedly connected to the outer wall of the output shaft of the third motor.

[0015] The above technical solution involves starting a third motor to remove dust from solar panel components. The output shaft rotates, driving a fourth bevel gear to rotate, which in turn drives the meshing third bevel gear to rotate, thereby rotating the roller brush. This roller brush effectively removes stubborn dust from the surface of the solar panel components. The blowing mechanism then disperses the dust, making it easier for the suction mechanism to absorb the cleaned dust and preventing it from re-adhering to the surface of the solar panel components, thus improving the cleaning quality.

[0016] Furthermore, the rotating shaft of the roller brush cylinder is slidably connected to the corresponding limiting hole, and the third bevel gear meshes with the fourth bevel gear.

[0017] Through the above technical solution, after the roller brush has been cleaning the solar panel components for a long time, dust will accumulate on its cleaning bristles. If it is not cleaned regularly, the accumulated dust will reduce the cleaning efficiency when cleaning the solar panel components, requiring multiple cleanings to clean them thoroughly, which greatly reduces the dust removal efficiency. At this time, the two first cylinders are activated, and the first connecting frame is contracted through the piston, thereby contracting the roller brush and bringing the roller brush closer to the dust removal mechanism. When the roller brush rolls, the cleaning bristles on the roller brush will touch the dust removal plate. Each time they touch, the dust on the roller brush will fall off, thus achieving dust removal from the roller brush.

[0018] Furthermore, the dust removal mechanism includes two second cylinders fixedly installed on both sides of the movable frame. A lifting frame is fixedly connected between the bottom ends of the pistons of the two second cylinders. A second connecting frame is rotatably connected to the center of the lifting frame. A fourth motor is fixedly installed on one side of the lifting frame. An installation plate is provided below the second connecting frame. A cleaning pad is fixedly connected to the bottom of the installation plate. A dust removal plate is fixedly connected to the top rear end of the installation plate. Limit rods are fixedly connected to the four top corners of the second connecting frame. Springs are sleeved on the outer sides of the multiple limit rods.

[0019] With the above technical solution, when cleaning the solar panel module, after the roller brush removes the dust, the cleaning pad can adhere to the surface of the solar panel module under the action of multiple springs. When the moving mechanism moves continuously, the cleaning pad can clean the residual dust on the surface of the solar panel module, making the dust removal more thorough and greatly improving the dust removal quality.

[0020] Furthermore, one end of the output shaft of the fourth motor is fixedly connected to the second connecting frame, the top ends of the plurality of springs are all fixedly connected to the second connecting frame, and the top ends of the plurality of limiting rods all penetrate the second connecting frame.

[0021] With the above technical solution, when the roller brush needs cleaning, two second cylinders are activated, and the pistons contract to move the mounting plate to the center of the roller brush. When the roller brush moves close to the dust removal plate, it rolls to achieve automatic cleaning. At the same time, when the cleaning pad needs cleaning, the fourth motor is activated, and the output shaft rotates to drive the second connecting frame to rotate 90 degrees. Then, the two second cylinders are activated again, and the pistons contract to move the mounting plate to the center of the roller brush. The roller brush then moves close to the cleaning pad, and it rolls to clean the dust attached to the cleaning pad, greatly improving the cleaning efficiency of the cleaning pad. No manual cleaning is required; the equipment operates automatically, improving overall operating efficiency.

[0022] Furthermore, the dust collection mechanism includes multiple dust collection heads fixedly installed on the top of the baffle, a third connecting pipe fixedly connected between the multiple dust collection heads, a second air pump fixedly installed inside the mounting box, a fourth connecting pipe fixedly connected between the second air pump and the third connecting pipe, and a fifth connecting pipe fixedly connected between the second air pump and the storage box.

[0023] The above technical solution involves activating a second air pump to draw air from multiple suction heads during the cleaning process, using the fourth and third connecting pipes. This allows the suction heads to draw in the cleaned dust, and the air is then transported to a storage box via a fifth connecting pipe. This mechanism can absorb dust during the cleaning of solar panel components, as well as dust from the roller brush and cleaning pad. Only periodic cleaning of the storage box is required to prevent dust from spreading back to the surface of the solar panel components.

[0024] The beneficial effects of the present invention are as follows: (1) By designing a guide rail assembly and a moving mechanism, the device can automatically move to the frame of the next row of fixed frames, thereby facilitating the dust removal of solar panel components on the fixed frames. The entire process does not require manual operation by staff, and the equipment is automatically transferred, which greatly improves the automation efficiency and saves labor costs; (2) The present invention can simultaneously blow, roll, sweep and vacuum the solar panel components through a jetting mechanism, a roller brush mechanism, a dust sweeping mechanism and a dust suction mechanism. Blowing can blow up the dust attached to the surface of the solar panel components, which is convenient for subsequent roller brushing. Rolling brush can clean up stubborn dust and improve the cleaning effect. Dust sweeping can clean the remaining dust on the solar panel components, which greatly improves the cleaning quality. Dust suction can suck away the dust and air after cleaning, preventing dust from re-attaching to the solar panel components, so that the overall dust removal effect is good and the efficiency is high.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figures 1-4As shown, a dust removal device for photovoltaic equipment in this embodiment includes a guide rail assembly 1. The guide rail assembly 1 includes a guide rail frame 101, and a support frame 102 is provided on the guide rail frame 101. Drive wheels 103 are installed on one side of the front and rear ends of the support frame 102, and driven wheels 104 are installed on the other side of the front and rear ends of the support frame 102. A first motor 105 is installed on one side of the front and rear ends of the support frame 102. One end of the output shaft of the two first motors 105 is fixedly connected to the corresponding drive wheel 103. A mounting frame 106 is fixedly connected to the top of the support frame 102, and a brush 107 is fixedly installed on the mounting frame 106. After dust removal of the first row of solar panel modules 7, when automatic dust removal of the next row of solar panel modules 7 is required, the two first motors 105 are started, and each drives the connected drive wheel through the rotation of its output shaft. Rotating 103, in conjunction with two driven wheels 104, moves the guide rail frame 101, thus moving the entire device. When it moves to the position of the fixed frame 8 on the next row of solar panel components 7, the support frame 102 stops moving and automatically moves on the frame of the fixed frame 8 of the next row through the moving mechanism 2, which facilitates the dust removal of the solar panel components 7 on the fixed frame 8. The whole process does not require manual operation by the staff, and the equipment moves automatically, which greatly improves the automation efficiency and saves labor costs. At the same time, before cleaning the next row of solar panel components 7, when the entire support frame 102 is moved out, the brush 107 can also automatically brush away the dust on the surface of the solar panel 204 on the moving mechanism 2, which greatly improves the light absorption rate of the solar panel 204, thus ensuring that the guide rail assembly 1 is always running automatically.

[0029] like Figures 1-9As shown, a moving mechanism 2 is installed on the guide rail assembly 1. The moving mechanism 2 includes a movable frame 201 mounted on the support frame 102. The movable frame 201 has slots 202 and limiting holes 203 on both sides. A solar panel 204 is fixedly installed on one side of the top of the movable frame 201, and a storage box 205 is fixedly installed on the other side of the top of the movable frame 201. An installation box 206 is fixedly installed at the center of the top of the movable frame 201. First pulleys 207 are installed at the four corners of the bottom of the movable frame 201. Two second pulleys 208 are installed on the inner surfaces of both sides of the movable frame 201. First bevel gears 209 are fixedly connected to the outer walls of the rollers of the two second pulleys 208. Second motors 210 are installed at the front ends of both sides of the movable frame 201. Second bevel gears 211 are fixedly connected to the outer walls of the output shafts of the two second motors 210. The center of the movable frame 201 is fixedly... When the solar panel assembly 7 needs automatic dust removal, the two second motors 210 are activated via the baffle 212. Each motor rotates its output shaft, driving the second bevel gear 211 to rotate, which in turn drives the meshing first bevel gear 209 to rotate. This, in turn, drives the two second pulleys 208 to rotate. Combined with the multiple first pulleys 207, the movable frame 201 can move at the edge of the fixed frame 8, facilitating dust removal of the solar panel assembly 7 on the fixed frame 8. The solar panel 204 provides power to the entire device. The dust cleaned from the solar panel assembly 7 can be stored in the storage box 205 for periodic cleaning. The two first bevel gears 209 mesh with their corresponding second bevel gears 211. The rotation of the first bevel gears 209 drives the two second pulleys 208 to rotate, causing the movable frame 201 to move. This mechanism allows for automatic movement, significantly improving dust removal efficiency.

[0030] like Figures 1-10 As shown, a blowing mechanism 3 is installed at the rear center of the moving mechanism 2. The blowing mechanism 3 includes multiple nozzles 301 fixedly installed at the bottom rear end of the baffle 212. A first connecting pipe 302 is fixedly connected between the multiple nozzles 301. A first air pump 303 is installed in the mounting box 206. A second connecting pipe 304 is fixedly connected between the first connecting pipe 302 and the first air pump 303. When cleaning the solar panel assembly 7, the first air pump 303 is started, so that the first air pump 303 draws in outside air through the upper air inlet valve, and then delivers the gas to the multiple nozzles 301 through the second connecting pipe 304 and the first connecting pipe 302. The multiple nozzles 301 blow air onto the surface of the solar panel assembly 7, thereby blowing away the attached dust and achieving preliminary cleaning. After blowing away a layer of attached dust, it is convenient for the subsequent dust removal by the roller brush mechanism 4.

[0031] like Figures 1-12As shown, a roller brush mechanism 4 is installed on the front end of the moving mechanism 2 near the air blowing mechanism 3. The roller brush mechanism 4 includes two first cylinders 401 fixedly installed on the rear ends of both sides of the movable frame 201. The front ends of the pistons of the two first cylinders 401 are fixedly connected to first connecting frames 402. A roller brush cylinder 403 is rotatably connected between the two first connecting frames 402. A third bevel gear 404 is fixedly connected to one end of the outer wall of the rotating shaft of the roller brush cylinder 403. A third motor 405 is fixedly installed on the top of one of the first connecting frames 402. A fourth bevel gear 406 is fixedly connected to the outer wall of the output shaft of the third motor 405. When cleaning the solar panel assembly 7, the third motor 405 is started, and the output shaft rotates to drive the fourth bevel gear 406 to rotate, thereby driving the meshing third bevel gear 404 to rotate, thereby driving the roller brush cylinder 403 to rotate, thus brushing the stubborn dust adhering to the surface of the solar panel assembly 7 to remove dust. This is then combined with the air blowing mechanism 3 to brush the roller brush. The dust is blown away, making it easier for the dust collection mechanism 6 to absorb the cleaned dust, preventing the dust from re-adhering to the surface of the solar panel assembly 7 and improving the cleaning quality. The rotating shaft of the roller brush cylinder 403 is slidably connected to the corresponding limiting hole 203, and the third bevel gear 404 and the fourth bevel gear 406 mesh. After the roller brush cylinder 403 cleans the solar panel assembly 7 for a long time, dust will adhere to its cleaning bristles. If it is not cleaned regularly, the adhered dust will reduce the cleaning efficiency when cleaning the solar panel assembly 7, and multiple cleanings will be required to clean it, which will greatly reduce the dust removal efficiency. At this time, the two first cylinders 401 are activated, and the first connecting frame 402 is contracted by the piston, thereby contracting the roller brush cylinder 403, so that the roller brush cylinder 403 is close to the dust sweeping mechanism 5. When the roller brush cylinder 403 rolls, the cleaning bristles on the roller brush cylinder 403 will touch the dust removal plate 507. Each time it touches, the dust on the roller brush cylinder 403 will fall off, realizing the dust removal of the roller brush cylinder 403.

[0032] like Figures 1-14As shown, a dust-sweeping mechanism 5 is installed on the front end of the moving mechanism 2 near the roller brush mechanism 4. The dust-sweeping mechanism 5 includes two second cylinders 501 fixedly installed on both sides of the movable frame 201. A lifting frame 502 is fixedly connected between the bottom ends of the pistons of the two second cylinders 501. A second connecting frame 503 is rotatably connected to the center of the lifting frame 502. A fourth motor 504 is fixedly installed on one side of the lifting frame 502. A mounting plate 505 is provided below the second connecting frame 503. A cleaning pad 506 is fixedly connected to the bottom of the mounting plate 505. A dust removal plate 507 is fixedly connected to the top rear end of the 05. Limiting rods 508 are fixedly connected to the four corners of the top of the second connecting frame 503. Springs 509 are sleeved on the outer sides of each limiting rod 508. When cleaning the solar panel assembly 7, after dust removal by the roller brush 403, the cleaning pad 506 adheres to the surface of the solar panel assembly 7 under the action of the multiple springs 509. As the moving mechanism 2 continues to move, the cleaning pad 506 cleans the residual dust from the surface of the solar panel assembly 7, making the dust removal more thorough. This significantly improves dust removal quality. One end of the output shaft of the fourth motor 504 is fixedly connected to the second connecting frame 503. The tops of multiple springs 509 are also fixedly connected to the second connecting frame 503. The tops of multiple limit rods 508 pass through the second connecting frame 503. When the roller brush cylinder 403 needs cleaning, two second cylinders 501 are activated, and their pistons contract, causing the mounting plate 505 to move to the center position of the roller brush cylinder 403. When the roller brush cylinder 403 moves close to the dust removal plate 507, it rolls, achieving automatic cleaning. When the cleaning pad 506 needs to be cleaned, the fourth motor 504 is started, which drives the second connecting frame 503 to rotate 90 degrees through the output shaft. Then, the two second cylinders 501 are started, and the pistons contract, causing the mounting plate 505 to move to the center position of the roller brush cylinder 403. Then, the roller brush cylinder 403 moves close to the cleaning pad 506, and the roller brush cylinder 403 rolls to clean the dust attached to the cleaning pad 506, which greatly improves the cleaning efficiency of the cleaning pad 506. No manual cleaning is required. The equipment operates automatically, improving the overall operating efficiency.

[0033] like Figures 1-7As shown, a dust collection mechanism 6 is installed at the top center of the moving mechanism 2. The moving mechanism 2 can move on the fixed frame 8 and remove dust from the solar panel assembly 7 through the roller brush mechanism 4 and the dust sweeping mechanism 5. The dust collection mechanism 6 includes multiple dust collection heads 601 fixedly installed on the top of the baffle 212. A third connecting pipe 602 is fixedly connected between the multiple dust collection heads 601. A second air pump 603 is fixedly installed in the mounting box 206. A fourth connecting pipe 604 is fixedly connected between the second air pump 603 and the third connecting pipe 602. A fifth connecting pipe 604 is fixedly connected between the second air pump 603 and the storage box 205. When the connecting pipe 605 absorbs the cleaned dust, the second air pump 603 is activated, and air is drawn from multiple suction heads 601 through the fourth connecting pipe 604 and the third connecting pipe 602, so that multiple suction heads 601 suck up the cleaned dust. The extracted dust and gas are transported to the storage box 205 through the fifth connecting pipe 605. This mechanism can absorb dust when cleaning the solar panel module 7, as well as dust when cleaning the roller brush 403 and cleaning pad 506. Only periodic cleaning of the storage box 205 is required afterward to prevent dust from spreading back to the surface of the solar panel module 7.

[0034] The working principle of this embodiment is as follows: When cleaning the solar panel assembly 7, the first air pump 303 is started, which draws in outside air through the upper air inlet valve and then delivers the air to multiple nozzles 301 through the second connecting pipe 304 and the first connecting pipe 302. The multiple nozzles 301 blow air onto the surface of the solar panel assembly 7, thereby blowing away the attached dust and achieving initial cleaning. Then, the third motor 405 is started, and the output shaft rotates to drive the fourth bevel gear 406 to rotate, which in turn drives the meshing third bevel gear 404 to rotate, thereby driving the roller brush cylinder 403 to rotate, thus brushing away the dust on the surface of the solar panel assembly 7. Dust removal is achieved by simultaneously activating two second motors 210, each of which drives the second bevel gear 211 to rotate via its output shaft. This, in turn, drives the meshing first bevel gear 209 to rotate, which in turn drives the two second pulleys 208 to rotate. In conjunction with multiple first pulleys 207, the movable frame 201 can move at the edge of the fixed frame 8, thereby thoroughly removing dust from the solar panel assembly 7. At the same time, under the action of multiple springs 509, the cleaning pad 506 can adhere to the surface of the solar panel assembly 7. As the moving mechanism 2 continues to move, the cleaning pad 506 can clean the residual dust on the surface of the solar panel assembly 7, making the dust removal more thorough. When it is necessary to remove dust from the next row of solar panel modules 7, the two first motors 105 are started, and the output shafts of both motors drive the connected drive wheels 103 to rotate. In conjunction with the two driven wheels 104, the drive wheels move on the guide rail frame 101, thereby moving the entire device. When the device moves to the position of the fixed frame 8 on the next row of solar panel modules 7, the support frame 102 stops moving and moves automatically on the frame of the fixed frame 8 on the next row through the moving mechanism 2, thereby removing dust from the solar panel modules 7 on the next row of fixed frames 8. When the roller brush cylinder 403 needs to be cleaned, the two second cylinders 501 are activated, and both retract through pistons, causing the mounting plate 505 to move to the center position of the roller brush cylinder 403. At this time, the two first cylinders 401 are activated, and both retract through pistons the first connecting bracket 402, thereby retracting the roller brush cylinder 403, so that the roller brush cylinder 403 is close to the dust removal plate 507. When the roller brush cylinder 403 rolls, the cleaning bristles on the roller brush cylinder 403 will touch the dust removal plate 507. Each time it touches, the dust on the roller brush cylinder 403 will fall off, thus achieving dust removal of the roller brush cylinder 403. When the cleaning pad 506 needs to be cleaned, the fourth motor 504 is started, which drives the second connecting frame 503 to rotate 90 degrees through the rotation of the output shaft. Then, the two second cylinders 501 are started, and the pistons contract, causing the mounting plate 505 to move to the center position of the roller brush cylinder 403. Then, the roller brush cylinder 403 moves close to the cleaning pad 506, and the roller brush cylinder 403 rolls to clean the dust attached to the cleaning pad 506. No manual cleaning is required, and the equipment operates automatically.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
