Technical Field

[0001] The invention relates to photovoltaic water supply equipment, in particular to high-efficiency and energy-saving photovoltaic-driven variable-frequency water supply equipment. Background Art

[0002] Variable frequency water supply equipment is also called variable frequency speed regulation constant pressure water supply equipment. It uses AC inverter to drive the water pump motor and can adjust the running speed of the water pump in real time according to the changes in the pipe network pressure to achieve the purpose of constant pressure. Its core technology is variable speed operation, so variable frequency water supply equipment can also be called variable speed water supply equipment. Currently, commonly used variable frequency water supply equipment generally needs to be connected to the power supply system for use. The requirements for the layout of the power supply line are high, and the layout and installation steps are relatively cumbersome. In order to solve the above problems, people have developed photovoltaic variable frequency water supply equipment with photovoltaic power as the power source. It converts and stores the daytime light energy for the equipment to use. It has the advantages of clean energy use and circuit dependence requirements.

[0003] In actual use, the photovoltaic panels used to collect light energy in the photovoltaic modules of the photovoltaic-driven variable frequency water supply equipment need to be stored in the open air.

Therefore, it is necessary to clean the surface of the photovoltaic panels in the photovoltaic modules regularly.

[0004] During cleaning and maintenance of existing equipment, a cleaning brush is often used to clean the surface of the photovoltaic panel. During the cleaning process, multiple reciprocating cleaning operations are often required to meet the final cleaning effect. However, during actual cleaning, the cleaning brush does not clean itself after each cleaning cycle, resulting in a gradual decrease in cleaning ability during long-term operation, which greatly reduces the cleaning efficiency of the photovoltaic panel in the equipment.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0023] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, in an embodiment of the present invention, a high-efficiency and energy-saving photovoltaic-driven variable frequency water supply device includes a water supply structure and a photovoltaic structure, wherein the photovoltaic structure is electrically connected to the water supply structure and is used to provide stable power supply to the water supply structure; Wherein, the water supply structure comprises a variable frequency water supply pump 1, and the variable frequency water supply pump 1 is connected to the delivery pipeline; The photovoltaic structure includes a photovoltaic support 2, a distribution box 3 and a cleaning component 5. A photovoltaic panel 4 is fixedly placed in the installation frame on the upper part of the photovoltaic support 2. The distribution box 3 is fixedly installed at the bottom of the photovoltaic support 2, and a storage battery and a photovoltaic inverter are placed therein. The cleaning component 5 includes a mounting box 501, a main cleaning brush 513 and a movable semi-cylinder 502. The mounting box 501 is slidably mounted on the photovoltaic support 2 along the extension direction of the bottom edge of the photovoltaic panel 4, and is driven by the driving component 6 on the photovoltaic support 2 to move linearly. A small cleaning brush and a plurality of spray pipes 512 are installed in the mounting box 501, wherein the small cleaning brush can be in rotational contact with the large cleaning brush. The two ends of the rotating shaft of the main cleaning brush 513 are rotatably connected to the sliding blocks 506 installed at the two ends of the installation box 501, respectively. The movable semi-cylinder 502 is rotatably installed in the installation box 501 and driven to rotate by the rotating assembly 504 on the installation box 501. Two groups of the sliding blocks 506 are elastically installed on the corresponding driving plates 505, and one group of the driving plates 505 is transmission-connected to the rotating assembly 504 through the transmission assembly 510. The opening on the cylinder body of the movable semi-cylinder 502 can be used for the main cleaning brush 513 to extend. The scraper assembly 503 is rotatably installed at the opening of the movable semi-cylinder 502, and the scraper assembly 503 can scrape and clean the surface of the photovoltaic panel 4; The rotating half cylinder can be driven to rotate by the rotating component 504, and the bottom opening of the installation box 501 can be sealed by the rotating half cylinder. At the same time, the main cleaning brush 513 is moved and stored in the installation box 501 by the transmission belt 5102 of the transmission component 510, and the main cleaning brush 513 is cleaned by the auxiliary cleaning brush 511 and multiple groups of spray pipes 512.

[0024] Specifically, the present invention can clean the main cleaning brush 513 separately during the cleaning process without removing the main cleaning brush 513. For example, when the cleaning component needs to be reset for cleaning after completing a cleaning process in one direction, the rotating component 504 can cooperate with the transmission component 510, and the rotating component 504 drives the movable semi-cylinder 502 to rotate and seal the bottom of the installation box 501, and drives the movable cleaning brush 513 to move to the inside of the installation box 501 for storage, and the bottom of the main cleaning brush 513 is lifted away from the panel surface of the photovoltaic panel 4, and finally completely stored in the installation box 501. At the same time, during the rotation of the movable semi-cylinder 502, the movable semi-cylinder 502 seals the bottom opening of the installation box 501, and a cylindrical closed cavity is formed between the rotating semi-cylinder and the installation box 501. In the closed cavity, the main cleaning brush 513 can be cleaned by the spray cleaning operation of the auxiliary cleaning brush 511 and the spray pipe 512; At the same time, during the cleaning process, since the photovoltaic panel 4 is often set to an inclined state in order to cater to the angle of light, the cleaning component is also parallel to the inclination angle of the photovoltaic panel 4 when working, so that when the main cleaning brush 513 is cleaning in the closed cavity composed of the installation box 501 and the movable half barrel, the cleaning wastewater can be discharged through the bottom opening of the closed cavity, avoiding the cleaning wastewater from contaminating the main cleaning brush 513, thereby achieving the cleaning of the cleaning brush.

[0025] like Figure 2 and Figure 7 As shown, in the embodiment of the present invention, a group of positioning sliders 7 are respectively installed at both ends of the installation box 501, and the two groups of positioning sliders 7 are respectively slidably installed in the guide rails set on the upper and lower sides of the back of the photovoltaic bracket 2, and the driving component 6 is used to drive the correspondingly connected positioning sliders 7 to slide, and the two groups of positioning sliders 7 slide along the corresponding guide rails to improve the stability of the installation box 501 when moving and sliding on the photovoltaic bracket 2; The driving assembly 6 includes a driving screw 601 and a first control motor 601. The driving screw 601 is rotatably installed in the corresponding guide track, and one end of the driving screw 601 is transmission-connected to the first control motor 601. The driving screw 601 forms a spiral transmission with the positioning slider 7 installed in the corresponding guide track. A fixed inner nut for transmission connection with the driving screw 601 is installed on the corresponding positioning slider 7. When the driving assembly 6 is driven, the first control motor 601 is turned on to drive the corresponding driving screw 601 to rotate, and the positioning slider 7 and the installation box 501 connected to the transmission belt 5102 move linearly. Of course, the driving component 6 in the present invention may also be replaced by other components with linear driving capabilities, such as a gear rack mechanism or a pulley structure, etc. The present invention does not impose a rigid requirement on the selection of the driving component 6.

[0026] like Figure 3 , Figure 5 as well as Figure 6As shown, in the embodiment of the present invention, the rotating assembly 504 includes a driving gear 5041, a second control motor 5042 and an arc-shaped rack 5043. The second control motor 5042 is fixedly mounted on the upper side of the mounting box 501. The driving gear 5041 is coaxially mounted on the rotating shaft of the second control motor 5042. The arc-shaped rack 5043 is fixedly mounted in a mounting groove provided on the outer arc wall of the movable semi-cylinder 502, and is meshed and rotated with the driving gear 5041 through a connecting hole provided on the mounting box 501. When the movable semi-cylinder 502 needs to be driven to rotate, the second control motor is used to rotate the second control motor 5042. When the machine is turned on, 5042 drives the driving gear 5041 to rotate and drive, and through the meshing of the driving gear 5041 and the arc-shaped rack 5043, the movable half cylinder 502 is driven to slide in the sliding cavity in the installation box 501, wherein a plurality of sets of limiting arc plates 5021 are fixedly installed on the outer side of the movable half cylinder 502, and the plurality of sets of the limiting arc plates 5021 are rotatably installed in the guide grooves provided on the inner wall of the sliding cavity. Of course, in actual design, the driving gear 5041 and the arc-shaped rack 5043 selected in the present invention can also be replaced by other components with rotational driving capability, such as a worm gear structure, etc.

[0027] Furthermore, the transmission assembly 510 includes a transmission gear 5101 and a transmission spur rack 5103. The transmission gear 5101 is rotatably mounted on the upper end of the installation box 501 and is transmission-connected to the driving gear 5041 through a transmission belt 5102. The transmission spur rack 5103 is vertically fixedly mounted on the driving plate 505 and is meshed with the transmission gear 5101. In the invention, the linear movement of the sliding blocks 506 at both ends of the main cleaning brush 513 is transmission-connected with the rotary movement of the movable semi-cylinder 502. When the rotary assembly 504 drives the movable semi-cylinder 502 to rotate, the transmission of the transmission belt 5102 drives the driving gear 5041 to rotate synchronously. The transmission gear 5101 is meshed with the transmission spur rack 5103 on the driving plate 505, driving the transmission spur rack 5103 and the driving plate 505 and the sliding block 506 connected thereto to perform linear movement. When the cleaning brush 513 is in contact with the photovoltaic panel 4, the movable semi-cylinder 502 is driven to rotate by the rotary assembly 504. At this time, the movable semi-cylinder 502 docks the opening on the upper side with the bottom opening of the installation box 501 to form a channel for the main cleaning brush 513 to extend out. At the same time, the sliding blocks 506 at both ends of the main cleaning brush 513 are elastically driven by the transmission spur rack 5103 to move outward from the inside of the installation box 501 and come into contact with the photovoltaic panel 4. Conversely, when the main cleaning brush 513 needs to be cleaned, the movable semi-cylinder 502 is reset to rotate by the rotary assembly 504. At this time, the movable semi-cylinder 502 seals the opening at the bottom of the installation box 501. During the sealing process, the main cleaning brush 513 is elastically driven by the sliding block 506 to reset and move to the inner wall of the installation box 501, so that the main cleaning brush 513 is stored in the placement cavity formed by the installation box 501 and the movable semi-cylinder 502. Furthermore, a plurality of groups of fixed columns 508 are fixedly installed at the bottom of the driving plate 505, and the plurality of groups of fixed columns 508 are slidably connected to the corresponding sliding blocks 506, and a connecting spring 509 for elastically connecting the driving plate 505 and the sliding block 506 is wound around the fixed outer side. When the main cleaning brush 513 in the present invention is driven by the transmission spur rack 5103 to be pressed against the surface of the photovoltaic panel 4, the plurality of groups of connecting springs 509 are in a compressed state at this time. The main cleaning brush 513 is kept pressed against the surface of the photovoltaic panel 4 through the elastic force support of the compression of the various connecting springs 509, thereby ensuring the cleaning efficiency and quality of the main cleaning brush 513 when rotating.

[0028] like Figure 7 As shown, in the embodiment of the present invention, a first driven gear 515 and a second driven gear 514 are coaxially fixedly installed on the rotating shafts of the main cleaning brush 513 and the auxiliary cleaning brush 511, respectively. When the main cleaning brush 513 is driven to be stored at the top of the movable semi-cylinder 502, the first driven gear 515 is meshed and connected with the second driven gear 514. The main cleaning brush 513 in the present invention is driven to rotate by an independent third control motor 507. When the main cleaning brush 513 is stored in the closed chamber composed of the installation box 501 and the movable semi-cylinder 502, when the cleaning operation is performed, the main cleaning brush 513 can be driven to rotate accordingly by the third control motor 507, and the auxiliary cleaning brush 511 can be driven to rotate by the meshing of the first driven gear 515 and the second driven gear 514. The cleaning brush is cleaned by the relative rotation of the main cleaning brush 513 and the auxiliary cleaning brush 511 and the spraying operation of the multiple groups of spray pipes 512. Of course, in actual design, the auxiliary cleaning brush 511 can also be fixedly installed in the installation box 501. In this case, the main cleaning brush 513 can rotate independently to contact the bottom of the auxiliary cleaning brush 511 to clean the surface.

[0029] like Figure 6 and Figure 7 As shown, in an embodiment of the present invention, the scraper assembly 503 includes a transmission arc plate 5031 and a cleaning scraper 5032. One end of the transmission arc plate 5031 is rotatably connected to one end of the opening of the movable semi-cylinder 502. The cleaning scraper 5032 is slidably installed on the other end of the movable arc plate and is elastically connected to the movable guard plate. A guide column 5033 is fixedly installed on one side of the transmission arc plate 5031. The guide column 5033 is slidably connected to a guide arc groove 5034 fixed at the corresponding end of the installation box 501. The guide arc groove 5034 is used to synchronously drive the transmission arc plate to rotate when the movable semi-cylinder 502 rotates. The cleaning scraper 5032 can slide relatively to the transmission arc plate 5031 during the process of force extrusion.

[0030] Specifically, the scraper assembly 503 of the present invention can be in contact with the surface of the photovoltaic panel 4 by the cleaning scraper 5032 installed at the end thereof when the main cleaning brush 513 extends out of the installation box 501 for cleaning. When the main cleaning brush 513 is cleaning, the installation box 501 drives the cleaning scraper 5032 to move, and the surface of the photovoltaic panel 4 is scraped to further improve the cleaning ability of the main cleaning brush 513. At the same time, the transmission arc plate 5031 and the cleaning scraper 5032 can rotate in the movable semi-cylinder 502. When the main cleaning brush 513 is stored, the guide column 5033 slides along the guide arc groove 5034, driving the transmission arc plate 5031 and the cleaning brush scraper to rotate, so that they are on the same axis as the movable half cylinder 502, and are stored in the installation box 501 along with the movable half cylinder 502. At the same time, after the movable half cylinder 502 is stored in the installation box 501, the auxiliary cleaning brush 511 can clean the cleaning scraper 5032, thereby ensuring the cleanliness of the cleaning scraper 5032 and the subsequent hanging and removal ability of the cleaning scraper 5032.

[0031] In summary, the present invention is a highly efficient and energy-saving photovoltaic-driven variable frequency water supply device. By improving the cleaning component 5 in the photovoltaic structure driven by photovoltaic, the installation box 501, the main cleaning brush 513 and the movable semi-cylinder 502 are designed, and a small cleaning brush and a plurality of spray pipes 512 are installed in the installation box 501, so that the present invention is used; 1. When it is necessary to use the cleaning component 5 to clean the surface of the photovoltaic panel 4: The movable half cylinder 502 is driven to rotate by the rotary assembly 504, so that the opening on the movable half cylinder 502 is connected with the bottom opening of the installation box 501 to form a channel, and the main cleaning brush 513 is driven by the two sets of driving plates 505 and the sliding block 506 when the movable half cylinder 502 rotates, so that it moves outward from the installation box 501 and comes into close contact with the photovoltaic panel 4; When the movable half cylinder 502 is rotating and docking, the transmission arc plate 5031 installed at the end of the movable half cylinder 502 is deflected in the process of extending out of the installation box 501 under the transmission action of the guide column 5033 and the guide slide groove, driving the cleaning scraper 5032 elastically installed at its end to press and contact with the surface of the photovoltaic panel 4, and scraping the surface of the photovoltaic panel 4; 2. When it is necessary to clean the main cleaning brush 513 in the cleaning assembly 5: The movable half cylinder 502 is driven to rotate by resetting the rotary assembly 504, and at this time, the movable half cylinder 502 seals the opening at the bottom of the installation box 501, and in the sealing process, the main cleaning brush 513 is elastically driven by the sliding block 506 to reset and move to the inner wall of the installation box 501, so that the main cleaning brush 513 is stored in the placement cavity formed by the installation box 501 and the movable half cylinder 502, and the cleaning brush is cleaned by the main cleaning brush 513 and the auxiliary cleaning brush 511 rotating towards each other, and the spraying operation of the multiple groups of spray pipes 512, and the cleaning wastewater can be discharged through the bottom opening of the closed cavity to avoid the cleaning wastewater from contaminating the main cleaning brush 513, thereby cleaning the cleaning brush; At the same time, after the movable half cylinder 502 is stored in the installation box 501, the auxiliary cleaning brush 511 can be used to clean the cleaning scraper 5032, thereby ensuring the cleanliness of the cleaning scraper 5032 and the subsequent hanging and removing ability of the cleaning scraper 5032.
