[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) This intelligent locking device for valves is provided with a limit mechanism, etc., so that during normal use, authorized personnel can control the forward and reverse rotation of the motor by inputting a password through the password lock. The rotation of the motor drives the rotation of the rotating rod and the worm, thereby driving the rotation of the worm wheel and the valve stem, and then driving the rotation of the ball, so that the ball can be closed and opened. Moreover, when an unexpected situation such as power failure occurs, the operator can manually turn the rocker counterclockwise. The rotation of the rocker drives the rotation of the rotating rod and the worm, thereby driving the rotation of the worm wheel and the valve stem, and then driving the rotation of the ball, so that the valve body is closed. It is more convenient, faster, safer and more reliable to use. At the same time, under the action of the first spring, the side of the plug and the rotating rod are When the lever is rotated, the plug slides on the side wall of the lever. When the plug is aligned with the slot, the plug can be inserted into the slot under the action of the first spring, thereby limiting the lever. At this time, the rocker wheel cannot be rotated to avoid being opened, that is, the valve body is locked. When it needs to be opened again, the electromagnet is energized first. After the electromagnet is energized, it attracts the iron block, causing the moving block and the plug to move downward. At the same time, the first spring is compressed and the plug is withdrawn from the slot. At this time, the lever is no longer limited. Then, authorized personnel can input the password through the password lock to control the motor to rotate, thereby driving the ball to rotate and open. It is more convenient, quick, safe and reliable to use.

[0017] (2) This intelligent locking device for valves is provided with a cleaning mechanism, etc. When the valve body needs to be closed, the ball is rotated and closed by a motor or a rocker. At the same time, when the ball rotates, the pivot and the ring are driven to rotate. When the hemispherical protrusion abuts against the lower end of the first push rod, the fixed ring is pushed to move upward. At the same time, the airbag is compressed. When the hemispherical protrusion passes over the lower end of the first push rod, the fixed ring can move downward and reset under the action of the airbag. This reciprocating movement can make the fixed ring move up and down, and drive the bristles to move synchronously, so that the surface of the ball can be automatically cleaned when the ball rotates to open or close, thereby ensuring the locking effect.

[0018] (3) This intelligent locking device for valves is provided with a driving mechanism, etc. When the valve body is closed, when the airbag is squeezed, the air pressure in the airbag gradually increases, thereby pushing the piston to move away from the airbag. At the same time, the second spring is compressed, and the movement of the piston drives the movement of the first moving plate and the moving rod, and then drives the rack to move, thereby driving the gear and the rotating shaft to rotate, and then drives the filter plate to rotate ninety degrees. This reciprocating process can filter the water passing through the valve body under the action of the filter plate to ensure the locking effect.

[0019] (4) This intelligent locking device for valves, by setting up a protective mechanism, etc., when the valve body is closed, the pivot rotates, and the rotation of the pivot drives the synchronous rotation of the second push rod. After the ball rotates and closes, the second push rod abuts against the second inclined surface, thereby pushing the push frame to move away from the valve body, and at the same time, drives the movable frame and the push block to move synchronously, and the fourth spring is compressed. At this time, the push block is separated from the top of the second T-shaped guide rod, so that the second movable plate can move upward and reset under the action of the third spring, so that the sewage can enter the fixed box, thereby reducing the impact of the water hammer phenomenon on the valve body, ensuring its use effect and life, and at the same time, ensuring the locking effect. When the valve body is opened, the push block can move and reset under the action of the fourth spring and make the first inclined surface abut against the upper end of the second T-shaped guide rod, thereby pushing the second movable plate to move downward, and at the same time, the third spring is compressed.

[0034] See also Figures 1-12 The present invention provides a technical solution: an intelligent locking device for a valve, comprising a valve body 101, a valve cover 102, a valve stem 103, a pivot 104, a ball 105, an inlet pipe 106 and an outlet pipe 107 arranged on a valve body 1, a worm gear 21 is fixedly provided on the side wall of the valve stem 103, and the top of the valve body 101 is fixedly connected to two symmetrically arranged support plates 11, the side wall of the support plate 11 is rotatably connected to a worm 13 through a rotating rod 12, and one end of the rotating rod 12 is fixedly connected to the worm 13. The end passes through the side wall of the valve cover 102 and is fixedly connected to the rocking wheel 14. The side wall of the support plate 11 is fixedly connected to the motor 15, and the output end of the motor 15 is fixedly connected to the other end of the rotating rod 12. A password lock 16 is provided on the top of the valve cover 102, and the motor 15 is electrically connected to the password lock 16. An annular air bag 17 is fixedly inserted in the water inlet pipe 106, and a fixing ring 18 is fixedly inserted in the air bag 17. A filter disc 20 is rotatably connected to the fixing ring 18 through a rotating shaft 19. The valve cover A limiting mechanism 2 is provided at the top of 102 for limiting the rotating rod 12, and a cleaning mechanism 4 is provided on the side wall of the fixing ring 18 for cleaning the ball 105. The rotation of the rotating shaft 19 is driven by the driving mechanism 5, and a protective mechanism 8 is provided in the water inlet pipe 106 for reducing the influence of the water hammer effect on the valve body 1. The valve body 1 is opened and closed by the password lock 16, making the locking more intelligent. At the same time, when an unexpected situation such as a power outage occurs, the operator can manually turn the rocker 14 counterclockwise to close the valve body 1, which is more convenient, faster, safer and more reliable to use; when the valve body 1 needs to be closed, the water passing through the valve body 101 can be filtered, and at the same time, the surface of the ball 105 can be automatically cleaned to ensure the locking effect, and the sewage can enter the fixed box 801, thereby reducing the influence of the water hammer phenomenon on the valve body 1, ensuring its use effect and life, and thus ensuring the locking effect.

[0035] The limiting mechanism 2 includes a slot 201 provided on the side wall of the rotating rod 12, and the top of the valve cover 102 is connected to a moving block 202 through the first moving mechanism 3, and the bottom of the moving block 202 is fixedly connected to an insert block 203. When an unexpected situation such as a power outage occurs, the operator can manually rotate the rocking wheel 14 counterclockwise. The rotation of the rocking wheel 14 drives the rotation of the rotating rod 12 and the worm 13, thereby driving the rotation of the worm wheel 21 and the valve stem 103, and then driving the rotation of the ball 105, thereby closing the valve body 1, which is more convenient to use. It is convenient, quick, safer and more reliable. At the same time, under the action of the first spring 304, the plug block 203 is abutted against the side wall of the rotating rod 12. When the rotating rod 12 rotates, the plug block 203 slides on the side wall of the rotating rod 12. When the plug block 203 is aligned with the slot 201, the plug block 203 can be inserted into the slot 201 under the action of the first spring 304, thereby limiting the rotating rod 12. At this time, the rocker 14 cannot be rotated to avoid being opened, that is, the valve body 1 has a locking effect.

[0036] The first moving mechanism 3 includes a fixed plate 301 fixedly connected to the top of the valve cover 102, and the bottom of the fixed plate 301 is fixedly connected to two symmetrically arranged sleeves 302, a sleeve rod 303 is inserted into the sleeve 302, and the lower end of the sleeve rod 303 is fixed to the top of the moving block 202, and a first spring 304 is sleeved on the side wall of the sleeve 302, an electromagnet 306 is fixedly connected to the bottom of the fixed plate 301, and an iron block 305 is fixedly connected to the top of the moving block 202. When it is necessary to open it again, the electromagnet 306 is energized first. After the electromagnet 306 is energized, it attracts the iron block 305, causing the moving block 202 and the insert block 203 to move downward. At the same time, the first spring 304 is compressed and the insert block 203 is withdrawn from the slot 201. At this time, the rotating rod 12 is no longer limited. Then, an authorized person can input a password through the password lock 16 to control the motor 15 to rotate, thereby driving the ball 105 to rotate and open, which is more convenient, faster, safer and more reliable to use.

[0037] The cleaning mechanism 4 includes a plurality of bristles 401 fixedly connected to the end of the fixing ring 18 and arranged in an array, and the side wall fixed sleeve of the pivot 104 is provided with a circular ring 402, and the top of the circular ring 402 is fixedly connected with a plurality of hemispherical protrusions 403 arranged in an array, and a first push rod 404 is inserted into the side wall of the water inlet pipe 106. The upper end of the first push rod 404 passes through the air bag 17 and is fixed to the side wall of the fixing ring 18, and the lower end of the first push rod 404 slides on the top of the circular ring 402. When the valve body 1 needs to be closed, the sphere 105 is rotated and closed by the motor 15 or the rocker 14. At the same time, When the sphere 105 rotates, it drives the pivot 104 and the ring 402 to rotate. When the hemispherical protrusion 403 abuts against the lower end of the first push rod 404, the fixing ring 18 is pushed upward. At the same time, the airbag 17 is compressed. When the hemispherical protrusion 403 passes over the lower end of the first push rod 404, the fixing ring 18 can move downward and reset under the action of the airbag 17. This reciprocating motion allows the fixing ring 18 to move up and down, and drives the bristles 401 to move synchronously, so that the surface of the sphere 105 can be automatically cleaned when it is rotated to open or close, thereby ensuring the locking effect.

[0038] The driving mechanism 5 includes an installation cavity 501 provided in the fixing ring 18, and the upper end of the rotating shaft 19 passes through the installation cavity 501 and is fixedly sleeved with a gear 502. The bottom of the installation cavity 501 is connected to a rack 503 through a second moving mechanism 6. When the valve body 1 is closed, when the airbag 17 is squeezed, the rack 503 is driven to move by the second moving mechanism 6, thereby pushing the gear 502 and the rotating shaft 19 to rotate, and then driving the filter disc 20 to rotate ninety degrees. This reciprocating process can filter the water passing through the valve body 1 under the action of the filter disc 20 to ensure the locking effect.

[0039] The second moving mechanism 6 includes a moving rod 601 inserted into the side wall of the installation cavity 501, and one end of the moving rod 601 is fixed to the side wall of the rack 503, and the other end of the moving rod 601 is fixedly connected to the first moving plate 602, and the side wall of the first moving plate 602 is fixedly connected to the piston 603, the other end of the piston 603 passes through the airbag 17, and the first moving plate 602 is connected to the end of the fixed ring 18 through the first reset mechanism 7. When the valve body 1 is closed, when the airbag 17 is squeezed, the air pressure in the airbag 17 gradually increases, thereby pushing the piston 603 to move away from the airbag 17. The movement of the piston 603 drives the movement of the first moving plate 602 and the moving rod 601, and then drives the rack 503 to move, thereby driving the gear 502 and the rotating shaft 19 to rotate.

[0040] The first reset mechanism 7 includes a support block 703 fixedly connected to the end of the fixed ring 18, and the side wall of the support block 703 is fixedly connected to two symmetrically arranged first T-shaped guide rods 701, the first movable plate 602 is sleeved on the side wall of the first T-shaped guide rod 701, and the side wall of the first T-shaped guide rod 701 is sleeved with a second spring 702, which guides and resets the movement of the first movable plate 602.

[0041] The protection mechanism 8 includes a fixed box 801 fixedly inserted into the side wall of the water inlet pipe 106, and a second movable plate 802 is connected to the fixed box 801 through a second reset mechanism 10. When the valve body 1 is closed, the pivot 104 rotates, and the rotation of the pivot 104 drives the synchronous rotation of the second push rod 908. After the ball 105 rotates and closes, the second movable plate 802 is moved upward and reset through the pushing mechanism 9, so that sewage can enter the fixed box 801, thereby reducing the impact of water hammer on the valve body 1, ensuring its use effect and life, and at the same time, ensuring the locking effect.

[0042] The second reset mechanism 10 includes two symmetrically arranged second T-shaped guide rods 1001 fixedly connected to the top of the second movable plate 802, and the upper ends of the second T-shaped guide rods 1001 pass through the top of the fixed box 801. The side walls of the second T-shaped guide rods 1001 are sleeved with third springs 1002, and the side walls of the fixed box 801 are provided with a pushing mechanism 9 for pushing the second T-shaped guide rods 1001, which guides and resets the movement of the second movable plate 802.

[0043] The pushing mechanism 9 includes two symmetrically arranged third T-shaped guide rods 901 fixedly connected to the side wall of the fixed box 801, and the side wall of the third T-shaped guide rod 901 is provided with a movable frame 902, the side wall of the third T-shaped guide rod 901 is provided with a fourth spring 903, and the top of the movable frame 902 is fixedly connected with a pushing block 904, the pushing block 904 includes a first inclined surface 905, and the bottom of the movable frame 902 is fixedly connected with a pushing frame 906, the pushing frame 906 includes a second inclined surface 907, and the side wall of the ring 402 is fixedly connected with a second pushing rod 908. When the valve body 1 is closed, the pivot 104 rotates, and the rotation of the pivot 104 drives the synchronous rotation of the second pushing rod 908, and the ball 105 is rotated. After rotation closing, the second push rod 908 abuts against the second inclined surface 907, thereby pushing the push frame 906 to move away from the valve body 101. At the same time, it drives the movable frame 902 and the push block 904 to move synchronously, and the fourth spring 903 is compressed. At this time, the push block 904 is disengaged from the top of the second T-shaped guide rod 1001, so that the second movable plate 802 can move upward and reset under the action of the third spring 1002. When the valve body 1 is opened, the push block 904 can move and reset under the action of the fourth spring 903 and make the first inclined surface 905 abut against the upper end of the second T-shaped guide rod 1001, thereby pushing the second movable plate 802 to move downward. At the same time, the third spring 1002 is compressed.

[0044] Working principle: During normal use, authorized personnel can input a password through the password lock 16 to control the forward and reverse rotation of the motor 15. The rotation of the motor 15 drives the rotation of the rotating rod 12 and the worm 13, thereby driving the rotation of the worm wheel 21 and the valve stem 103, and then driving the rotation of the ball 105, so that the ball 105 can be closed and opened. In addition, when an unexpected situation such as a power outage occurs, the operator can manually rotate the rocker 14 counterclockwise. The rotation of the rocker 14 drives the rotation of the rotating rod 12 and the worm 13, thereby driving the rotation of the worm wheel 21 and the valve stem 103, and then driving the rotation of the ball 105, thereby closing the valve body 1, making it more convenient, quick, safe and reliable to use.

[0045] At the same time, under the action of the first spring 304, the insert block 203 is pressed against the side wall of the rotating rod 12. When the rotating rod 12 rotates, the insert block 203 slides on the side wall of the rotating rod 12. When the insert block 203 is aligned with the slot 201, the insert block 203 can be inserted into the slot 201 under the action of the first spring 304, thereby limiting the rotating rod 12. At this time, the rocker 14 cannot be rotated, preventing it from being opened, that is, the valve body 1 has a locking effect. When it needs to be opened again, the electromagnet 306 is first energized. When the electromagnet 306 is energized, it attracts the iron block 305, causing the movable block 202 and the insert block 203 to move downward. At the same time, the first spring 304 is compressed and the insert block 203 is withdrawn from the slot 201. At this time, the rotating rod 12 is no longer limited. Then, an authorized person can enter a password through the password lock 16 to control the motor 15 to rotate, thereby driving the ball 105 to rotate and open, making it more convenient, faster, safer and more reliable to use.

[0046] When the valve body 1 needs to be closed, the ball 105 is rotated and closed by the motor 15 or the rocker 14. At the same time, when the ball 105 rotates, the pivot 104 and the ring 402 are driven to rotate. When the hemispherical protrusion 403 abuts against the lower end of the first push rod 404, the fixing ring 18 is pushed upward. At the same time, the airbag 17 is compressed. When the hemispherical protrusion 403 passes the lower end of the first push rod 404, the fixing ring 18 can move downward and reset under the action of the airbag 17. This reciprocating motion can make the fixing ring 18 move up and down, and drive the bristles 401 to move synchronously, so that the surface of the ball 105 can be automatically cleaned when it is rotated to open or close, thereby ensuring the locking effect.

[0047] At the same time, when the valve body 1 is closed, when the airbag 17 is squeezed, the air pressure in the airbag 17 gradually increases, thereby pushing the piston 603 to move away from the airbag 17. At the same time, the second spring 702 is compressed, and the movement of the piston 603 drives the movement of the first movable plate 602 and the movable rod 601, thereby driving the rack 503 to move, thereby driving the gear 502 and the rotating shaft 19 to rotate, and then driving the filter disc 20 to rotate 90 degrees. This reciprocating process can filter the water passing through the valve body 1 under the action of the filter disc 20, thereby ensuring the locking effect;

[0048] Furthermore, when the valve body 1 is closed, the pivot 104 rotates, and the rotation of the pivot 104 drives the synchronous rotation of the second push rod 908. After the ball 105 rotates and closes, the second push rod 908 abuts against the second inclined surface 907, thereby pushing the push frame 906 to move away from the valve body 101. At the same time, it drives the movable frame 902 and the push block 904 to move synchronously, and the fourth spring 903 is compressed. At this time, the push block 904 is separated from the top of the second T-shaped guide rod 1001, so that the second movable plate 802 can move upward and reset under the action of the third spring 1002, so that sewage can enter the fixed box 801, thereby reducing the influence of water hammer on the valve body 1, ensuring its use effect and life, and at the same time, ensuring the locking effect;

[0049] When the valve body 1 is opened, the push block 904 can move and reset under the action of the fourth spring 903 and make the first inclined surface 905 abut against the upper end of the second T-shaped guide rod 1001, thereby pushing the second movable plate 802 to move downward. At the same time, the third spring 1002 is compressed and pushes the filter disc 20 to rotate and reset, ensuring the normal flow of sewage.
