One end of the pushing plate is fixedly connected to a reciprocating frame, and a tooth groove is provided on one side of the reciprocating frame, and a gear is arranged on the inner side of the reciprocating frame, and the gear is meshed with the tooth groove, and a scraper is arranged inside the valve body.

[0015] Preferably, the scraper is an arc-shaped crescent structure, the valve body is fixedly mounted on the top of the base plate, and the shell is fixedly mounted on the top of the base plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, when the swing frame is driven by the push block, the turbine, the first rotating shaft and the rotating plate to move, the swing frame and the pushing plate are used to control the movement of the reciprocating frame, and then the tooth grooves on the inner side of the reciprocating frame are meshed with the gears, so that the gears start to rotate under the drive of the tooth grooves. When the reciprocating frame is a reciprocating motion trajectory, the gears are driven to rotate in a clockwise and counterclockwise alternating rotation motion trajectory. Therefore, when the gears drive the second rotating shaft to rotate together, the motion trajectory of the scraper at the top of the second rotating shaft is the same as the motion trajectory of the gears, so that the scraper starts to move in a back-and-forth swinging trajectory inside the valve body, so that the scraper starts to scrape the dirt on the inner wall of the valve body with its own swing, thereby forming a self-cleaning inside the valve body, thereby preventing the dirt from accumulating in the valve body for a long time and forming agglomerates. As the agglomerates become larger and larger, the water output may be affected, and even blockage may occur.

[0017] 2. In the present invention, since there is a valve core inside the valve body, when the valve is opened and closed, the valve core also rotates back and forth to achieve the effect of opening and closing the valve. Therefore, during the opening and closing process, the valve core will also clean and scrape away a part of the impurities on the inner wall of the valve body; due to the existence of the pause time, the inner wall of the valve body will not be fully cleaned during the rotation process. Therefore, during the self-cleaning process, the back and forth swing of the scraper is used to clean most of the inner wall of the valve body, and the opening and closing of the valve core is used to clean another small part, thereby ensuring the self-cleaning effect of the valve body during the cleaning process, and preventing the scraper from colliding with the valve core.

[0018] 3. In the present invention, the movement trajectory of the push plate is limited by the first limit frame, the limit plate and the second limit frame, and the limit slide groove is used to make the reciprocating frame slide on the surface of the limit slide rail. Because of the existence of the two limit slide rails, the reciprocating frame will not only avoid position changes in the vertical direction during the movement, but also avoid position changes in the horizontal direction. Therefore, when the reciprocating frame uses the internal tooth groove to drive the gear to rotate, a stable meshing state can be guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] 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 implementation regulations described 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.

[0022] Embodiment 1 Reference Figure 1-6 As shown: a valve with a self-cleaning function, comprising a bottom plate 1 and a valve body 3, the bottom plate 1 is located inside the valve body 3, a shell 6 is installed on one side of the valve body 3, a pipe 4 is fixedly connected between the shell 6 and the valve body 3, the valve body 3 and the shell 6 are fixedly connected at opposite ends, a flange 2 is fixedly connected, a power mechanism 7 is arranged inside the bottom plate 1, a turbine 72 is arranged inside the shell 6, and a first rotating shaft 71 is arranged inside the shell 6; The power mechanism 7 includes a fixed frame 73 and a swing frame 74. The fixed frame 73 is fixedly connected to a first limit frame 731 on one end surface, and a second limit frame 732 on the other end surface of the fixed frame 73. One end of the swing frame 74 is fixedly connected to a limit plate 741, and the other end of the swing frame 74 is fixedly connected to a push plate 742. The limit plate 741 is slidably arranged inside the first limit frame 731, and the push plate 742 is slidably arranged inside the second limit frame 732. A movable groove 743 is opened in the middle of the swing frame 74, and the inner side of the movable groove 743 slides. A pushing block 76 is rotatably provided, the bottom end of the first rotating shaft 71 passes through the shell 6, the first rotating shaft 71 passes through the shell 6, the first rotating shaft 71 is rotatably provided in the center of the fixed frame 73, one end of the first rotating shaft 71 is fixedly connected to a rotating plate 75, one end surface of the rotating plate 75 is rotatably connected to the pushing block 76, one end of the pushing plate 742 is fixedly connected to a reciprocating frame 77, a tooth groove 773 is provided on one side of the reciprocating frame 77, a gear 78 is provided on the inner side of the reciprocating frame 77, the gear 78 is meshed with the tooth groove 773, and a scraper 79 is provided inside the valve body 3.

[0023] In this embodiment, when the valve is opened to start conveying the fluid, the fluid flows inside the pipe 4 and also flows into the housing 6. At this time, the fluid contacts the surface of the turbine blade 72. During this process, due to the presence of the blades on the surface of the turbine 72 and the structural design and geometric shape of the blades, centripetal force and centrifugal force are generated when the fluid passes through. Under the action of such forces, the kinetic energy of the fluid is converted into the kinetic energy of the blades. Next, when the blades rotate, they can transfer their own kinetic energy to the first rotating shaft 71, so that the first rotating shaft 71 will also start to rotate. As the first rotating shaft 71 rotates, the rotating plate 75 on the surface of one end of the first rotating shaft 71 will also start to rotate. When the rotating plate 75 rotates, one end of the rotating plate 75 is connected to the first rotating shaft 71, and the other end of the rotating plate 75 is away from the first rotating shaft 71. Therefore, when the rotating plate 75 rotates, the pushing block 76 on the surface of one end of the rotating plate 75 away from the first rotating shaft 71 will start to make a circular motion.

[0024] Then, the pushing block 76 will not only move with the rotating plate 75, but also move inside the movable groove 743 on the swing frame 74. However, due to the structural design of the movable groove 743 and the swing frame 74, the pushing block 76 will also drive the swing frame 74 to move during the movement. At the same time, the swing frame 74 will also drive the limit plates 741 and the pushing plate 742 on both sides to move when it moves. When the pushing plate 742 moves, it will also drive the reciprocating frame 77 to move. Therefore, the movement trajectory of the reciprocating frame 77 is the same as the movement trajectory of the pushing plate 742.

[0025] Finally, when the swing frame 74 moves driven by the push block 76, the limit plate 741 is limited by the first limit frame 731, so that the swing frame 74 can only reciprocate left and right, and then the push plate 742 drives the reciprocating frame 77 to reciprocate. In addition, the tooth groove 773 on the inner side of the reciprocating frame 77 meshes with the gear 78, so that the gear 78 starts to rotate under the drive of the tooth groove 773, but because the reciprocating frame 77 is a reciprocating motion trajectory, the gear 78, when driven by the reciprocating frame 77 to rotate, has an alternating rotation motion trajectory of clockwise and counterclockwise. Therefore, when the gear 78 drives the second rotating shaft 791 to rotate together, the motion trajectory of the scraper 79 on the top of the second rotating shaft 791 is the same as the motion trajectory of the gear 78, so that the scraper 79 starts to move in a back and forth swinging trajectory inside the valve body 3, and the scraper 79 starts to scrape the dirt on the inner wall of the valve body 3 with its own swing, thereby forming a self-cleaning inside the valve body 3, thereby preventing dirt from accumulating in the valve body 3 for a long time and forming agglomerates. As the agglomerates become larger and larger, they may affect the water output and even cause blockage.

[0026] Embodiment 2 Figure 1-8 As shown, a valve with a self-cleaning function comprises a bottom plate 1 and a valve body 3, the bottom plate 1 is located inside the valve body 3, a shell 6 is installed on one side of the valve body 3, a pipe 4 is fixedly connected between the shell 6 and the valve body 3, and flanges 2 are fixedly connected at opposite ends of the valve body 3 and the shell 6, a power mechanism 7 is arranged inside the bottom plate 1, a turbine 72 is arranged inside the shell 6, and a first rotating shaft 71 is arranged inside the shell 6; The power mechanism 7 includes a fixed frame 73 and a swing frame 74. The fixed frame 73 is fixedly connected to a first limit frame 731 on one end surface, and a second limit frame 732 on the other end surface of the fixed frame 73. One end of the swing frame 74 is fixedly connected to a limit plate 741, and the other end of the swing frame 74 is fixedly connected to a push plate 742. The limit plate 741 is slidably arranged inside the first limit frame 731, and the push plate 742 is slidably arranged inside the second limit frame 732. A movable groove 743 is opened in the middle of the swing frame 74, and the inner side of the movable groove 743 slides. A pushing block 76 is rotatably provided, the bottom end of the first rotating shaft 71 passes through the shell 6, the first rotating shaft 71 passes through the shell 6, the first rotating shaft 71 is rotatably provided in the center of the fixed frame 73, one end of the first rotating shaft 71 is fixedly connected to a rotating plate 75, one end surface of the rotating plate 75 is rotatably connected to the pushing block 76, one end of the pushing plate 742 is fixedly connected to a reciprocating frame 77, a tooth groove 773 is provided on one side of the reciprocating frame 77, a gear 78 is provided on the inner side of the reciprocating frame 77, the gear 78 is meshed with the tooth groove 773, and a scraper 79 is provided inside the valve body 3.

[0027] The outer surface of the first rotating shaft 71 is fixedly connected to the turbine 72 , and the top of the first rotating shaft 71 is rotatably connected to the top of the inner cavity of the shell 6 .

[0028] A valve core 32 is disposed inside the valve body 3 , and a fixing rod 31 is fixedly connected to the top and bottom of the valve core 32 , and the bottom end of the fixing rod 31 is rotatably connected to the bottom of the inner cavity of the valve body 3 .

[0029] The top and bottom ends of the scraper 79 are fixedly connected with connecting blocks 792 , and the scraper 79 contacts the inner wall of the valve body 3 .

[0030] In this embodiment, when the swing frame 74 is moving, since the shape of the movable groove 743 inside the swing frame 74 is the same as the shape of the push block 76, the push block 76 has a movement trajectory that cannot drive the swing frame 74 to move. Therefore, when the push plate 742 is moving, there is a period of time when the movement of the push block 76 cannot drive the push plate 742 to move together. At this time, the push plate 742 will have a pause time, so that the reciprocating frame 77 will also have a pause time during the movement process, which will cause the scraper 79 to be unable to completely scrape the entire inner wall of the valve body 3 when it moves; Next, since there is a valve core 32 inside the valve body 3, when the valve is in the process of opening and closing, the valve core 32 also rotates back and forth to achieve the effect of opening and closing the valve. Therefore, during the process of opening and closing, the valve core 32 will also clean and scrape away some impurities on the inner wall of the valve body 3; Then, due to the presence of the rest time, the scraper 79 will not clean all aspects of the inner wall of the valve body 3 during the rotation process. Therefore, during the self-cleaning process, the scraper 79 will not collide with the valve core 32, which not only protects the scraper 79, but also avoids the impact and damage to the valve core 32, thereby causing a decrease in sealing performance; Therefore, during the self-cleaning process, the scraper 79 is used to swing back and forth to clean most of the inner wall of the valve body 3, and the valve core 32 is used to open and close to clean another small part, so that the interior of the valve body 3 is fully cleaned to ensure the self-cleaning effect of the valve body 3.

[0031] Embodiment 3 according to Figure 6-8As shown, one of the fixed rods 31 is movably sleeved with one of the connecting blocks 792, and the bottom of the other fixed rod 31 is rotatably connected to the other connecting block 792. The bottom of the scraper 79 is fixedly connected with a second rotating shaft 791, and the second rotating shaft 791 is rotatably connected to the bottom of the inner cavity of the valve body 3. The bottom end of the second rotating shaft 791 penetrates the valve body 3, and the bottom of the second rotating shaft 791 is fixedly connected to the gear 78. A valve stem 5 is arranged on the top of the valve body 3, and the bottom end of the valve stem 5 penetrates the valve body 3, and the bottom of the valve stem 5 is fixedly connected to one of the fixed rods 31. Limiting grooves 772 are provided on both sides of the reciprocating frame 77, and a limiting track 771 is slidably arranged inside the limiting groove 772, and one side of the limiting track 771 is fixedly connected to the inner wall of the bottom plate 1. The scraper 79 is an arc-shaped crescent-shaped structure, the valve body 3 is fixedly mounted on the top of the bottom plate 1, and the shell 6 is fixedly mounted on the top of the bottom plate 1.

[0032] The second stop frame 732 is used to stop the gear 78 and the second stop frame 733 is used to stop the gear 78. Next, when the gear 78 drives the second rotating shaft 791 to rotate, the connecting block 792 at the top of the scraper 79 will rotate on the surface of the fixed rod 31 at the top of the valve core 32, thereby ensuring that when the scraper 79 is in operation, due to the existence of the fixed rod 31 at the top of the valve core 32, the scraper 79 will not be skewed or offset when scraping dirt, and will maintain close contact with the inner wall of the valve body 3, and will also avoid movement interference due to skewness, and even cause the scraper 79 to be squeezed and damaged, thereby causing the scraper 79 to be broken into pieces, further aggravating the blockage of the valve body 3.

[0033] The use method and working principle of the device are as follows: when the valve is opened to start conveying fluid, the fluid flows inside the pipe 4 and also flows into the shell 6. At this time, the fluid contacts the surface of the turbine blade 72. In this process, due to the presence of the blades on the surface of the turbine 72 and the structural design and geometric shape of the blades, centripetal force and centrifugal force are generated when the fluid passes through. Under the action of such force, the kinetic energy of the fluid is converted into the kinetic energy of the blades. When the blades rotate, they can transfer their own kinetic energy to the first rotating shaft 71, so that the first rotating shaft 71 also starts to rotate. With the rotation of the first rotating shaft 71, the rotating plate 75 on one end surface of the first rotating shaft 71 also starts to rotate. When the rotating plate 75 rotates, since one end of the rotating plate 75 is connected to the first rotating shaft 71 and the other end of the rotating plate 75 is away from the first rotating shaft 71, when the rotating plate 75 rotates, the push block 76 on the surface of one end of the rotating plate 75 away from the first rotating shaft 71 starts to make a circular motion.

[0034] Next, the pushing block 76 will not only move with the rotating plate 75, but also move inside the movable groove 743 on the swing frame 74. However, due to the structural design of the movable groove 743 and the swing frame 74, the pushing block 76 will also drive the swing frame 74 to move during the movement. At the same time, the swing frame 74 will also drive the limit plates 741 and the pushing plates 742 on both sides to move when moving. When the limit plate 741 slides inside the first limit frame 731, it can limit the movement trajectory of the swing frame 74. When the push plate 742 moves, it will also be restricted by the second limit frame 732, thereby ensuring that deviation is avoided during the reciprocating motion. In addition, when the reciprocating frame 77 moves driven by the push plate 742, the limit slide groove 772 is utilized to make the reciprocating frame 77 slide on the surface of the limit track 771. Because of the existence of the two limit tracks 771, the reciprocating frame 77 will not only not change its vertical position during the movement, but also avoid changes in its horizontal position. Therefore, when the reciprocating frame 77 uses the internal tooth groove 773 to drive the gear 78 to rotate, a stable meshing state can be guaranteed.

[0035] When the push plate 742 moves, it also drives the reciprocating frame 77 to move. Therefore, the movement trajectory of the reciprocating frame 77 is the same as that of the push plate 742. When the swing frame 74 moves, the shape of the movable groove 743 inside the swing frame 74 is the same as that of the push block 76, so that there is a section of the movement trajectory of the push block 76 that cannot drive the swing frame 74 to move. Therefore, when the push plate 742 moves, there will be a period of time when the continued movement of the push block 76 cannot drive the push plate 742 to move together. At this time, the push plate 742 will have a pause time, so that the reciprocating frame 77 will also have a pause time during the movement process, which will cause the scraper 79 to be unable to completely scrape the entire inner wall of the valve body 3 when it moves; Then, since there is a valve core 32 inside the valve body 3, when the valve is opened and closed, the valve core 32 also rotates back and forth to achieve the effect of opening and closing the valve. Therefore, during the opening and closing process, the valve core 32 will also clean and scrape away some impurities on the inner wall of the valve body 3; due to the existence of the stop time, the scraper 79 will not clean all aspects of the inner wall of the valve body 3 during the rotation process. Therefore, during the self-cleaning process, the scraper 79 is used to clean most of the inner wall of the valve body 3 by swinging back and forth, and the opening and closing of the valve core 32 is used to clean another small part.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
