Description

Technical Field

[0001] The present invention relates to the technical field of airtightness detection, and particularly to a multi-station airtightness detection device for a globe valve. Background Art

[0002] A globe valve, also known as a stop valve, belongs to a forced-sealing valve. With the continuous development of related technologies, the application range of globe valves is becoming wider and wider, and at the same time, the performance requirements for globe valves are becoming more and more stringent. Airtightness detection is an essential detection item in the performance detection process of globe valves, which directly affects the use effect and service life of globe valves.

[0003] The patent with the patent announcement number CN212931827U discloses a globe valve airtightness detection device, which solves the problems of the accuracy of globe valve airtightness detection, detection efficiency, and automatic sorting of globe valves. The utility model includes an induction device and an inflation module; the inflation module is hollow inside and has a connection port adapted to the valve on the outside. The connection port communicates with the internal cavity of the inflation module. The inflation module is connected to the valve through the connection port. A sealed space can be formed between the inner cavity of the inflation module and the valve. The inflation module is also provided with an air inlet and an induction port, and both the air inlet and the induction port communicate with the inner cavity of the inflation module. Gas enters the inflation module through the air inlet; the induction device includes an inductor and a pressure probe, and the pressure probe is electrically connected to the inductor. The pressure probe is located inside the induction port. This patent has the advantages of simple structure, simple detection process, improved accuracy and detection efficiency of airtightness detection, and realization of automatic sorting.

[0004] However, this device still has deficiencies: although this device can improve the accuracy of airtightness detection, during the detection process, the picking and placing of the globe valve need to be manually positioned by the staff and then placed, resulting in an extended placement process time between the globe valve and the detection instrument. At the same time, a relatively large force is required to press and stabilize between the valve and the detection instrument to ensure the accuracy of the detection result, increasing the labor intensity of the staff. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a multi-station airtightness detection device for a globe valve, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A multi-station airtightness detection device for a globe valve includes a device main body. A driver is provided at the top of the device main body. A plurality of positioning grooves are equidistantly opened at the top of the driver. A sealing component is arranged inside the positioning grooves of the driver. An inflator is arranged at the center of the top of the driver. A hydraulic telescopic column is arranged on the outer wall of the inflator.

[0007] At the top edge of the driver, anti-offset devices are provided, the number of which is the same as and corresponds one-to-one to the number of positioning grooves. Inside the anti-offset device, an anti-pollution device is provided, and inside the anti-pollution device, an anti-adhesion device is provided;

[0008] The anti-offset device includes a detection component, the bottom of which is fixedly installed at the top edge of the driver. A connection component is fixedly installed on one side of the detection component close to the center of the driver. A positioning rod is fixedly installed at the edge of one side of the detection component close to the center of the driver. A gas transmission component is penetrated and slidably installed at one end of the positioning rod close to the center of the driver. An L-shaped plate is fixedly installed at the top edge of the device body. A limiting rail is fixedly installed at the top inner wall of the L-shaped plate. An electric telescopic rod is slidably installed inside the limiting rail. The bottom of the telescopic end of the electric telescopic rod is fixedly installed with a hydraulic clamp. A U-shaped pressing plate is fixedly installed on one side of the hydraulic clamp close to the L-shaped plate. An arc-shaped panel is fixedly installed on the outer wall of the positioning rod.

[0009] According to the above technical solution, the gas transmission component is communicated with an inflator through a hose. The gas transmission component is fixedly installed at the telescopic end of a hydraulic telescopic column on one side close to the inflator. The top arc surface of the arc-shaped panel is located on the movement track of the bottom of the U-shaped pressing plate. Place the stop valve inside the positioning groove at the top of the driver, and the bottom of the stop valve is in close contact with the sealing component. At the same time, start the hydraulic telescopic column. The telescopic end of the hydraulic telescopic column pushes the gas transmission component to slide along the top of the driver. At the same time, the gas transmission component will slide along the outer wall of the positioning rod for linear positioning during the sliding process. When one end of the gas transmission component is docked with the stop valve, it will push the stop valve to move towards the L-shaped plate. The stop valve drives the sealing component to slide synchronously along the inside of the positioning groove until the other end of the stop valve fits and connects with the interface of the connection component. At this time, start the electric telescopic rod. The telescopic end of the electric telescopic rod drives the hydraulic clamp to move downward. When the hydraulic clamp contacts the top of the stop valve, it automatically adjusts the clamping distance to tightly clamp the stop valve. The inflator inputs detection gas into the gas transmission component through the hose. The gas transmission component conveys gas into the stop valve. The detection component monitors whether the pressure changes to judge the airtightness of the stop valve. After the detection is completed, the hydraulic clamp first releases the clamping. The gas transmission component pulls the stop valve and the sealing component to reset. At this time, the electric telescopic rod clamps the stop valve through the hydraulic clamp and moves upward to disengage from the sealing component. The electric telescopic rod slides along the inside of the limiting rail towards the front part of the device body to facilitate the staff to take the stop valve. Then the electric telescopic rod slides back to its original position and repeats this process; when the hydraulic clamp moves downward, it drives the U-shaped pressing plate to move synchronously. During the vertical downward movement of the U-shaped pressing plate, its arc surface will contact the arc surface of the arc-shaped panel to generate a resistance force. At this time, the U-shaped pressing plate slides vertically downward along the vertical surface of the arc-shaped panel.

[0010] According to the above technical solution, the anti-pollution device includes an L-shaped fixed plate, an air extraction assembly, a delivery pipe, and a through plate. The bottom of the L-shaped fixed plate is fixedly installed on the fixed end of the electric telescopic rod near one side of the L-shaped plate. The bottom of the air extraction assembly is fixedly installed on the bottom inner wall of the L-shaped fixed plate. The top of the delivery pipe penetrates and is fixedly installed at the bottom of the air extraction assembly. The through plate is slidably installed inside the L-shaped plate through a spring. The bottom of the through plate is fixedly installed on the top of the L-shaped fixed plate. When the electric telescopic rod slides horizontally inside the limit rail, it drives the L-shaped fixed plate to move synchronously. The L-shaped fixed plate drives the air extraction assembly to move synchronously. The air extraction assembly drives the delivery pipe to move synchronously. After the air extraction assembly is started, it absorbs dirt particles or air ash within its moving range through the delivery pipe. At the same time, the L-shaped fixed plate pulls the through plate to slide synchronously along the inside of the L-shaped plate. When the electric telescopic rod resets, the above structure resets synchronously and repeats in this way.

[0011] According to the above technical solution, the anti-pollution device further includes a U-shaped transmission plate, a hinge plate, a rifled rod, a sliding ring, and a plurality of dust-removing net plates. The bottom of one end of the U-shaped transmission plate is fixedly installed on the top of the through plate. The other end of the U-shaped transmission plate is provided with a U-shaped groove. The top of the hinge plate is hinged inside the U-shaped groove of the U-shaped transmission plate. The bottom of the rifled rod is rotatably installed on the top of the driver. The sliding ring penetrates and is threadedly connected to the outer wall of the rifled rod. A plurality of the dust-removing net plates are fixedly installed on the outer wall of the rifled rod.

[0012] According to the above technical solution, a torsion spring is provided between the top of the hinge plate and the U-shaped transmission plate. The outer wall of the sliding ring is hinged to the bottom of the hinge plate. A plurality of the dust-removing net plates are equidistantly distributed on the outer wall of the rifled rod. When the through plate moves horizontally, it pulls the U-shaped transmission plate to move synchronously. The U-shaped groove of the U-shaped transmission plate drives the hinge plate to move synchronously. The bottom of the hinge plate is restricted by the sliding ring, causing its hinge shaft to start rotating. At this time, the hinge plate pushes the sliding ring to slide downward along the outer wall of the rifled rod with the hinge shaft as the axis. When the sliding ring slides, it drives the threadedly connected rifled rod to rotate around the top of the driver, and the rifled rod drives the dust-removing net plates to rotate.

[0013] According to the above technical solution, the anti-adhesion device includes a U-shaped frame, a plurality of friction wheels, a reciprocating screw rod, a plurality of collecting plates, a through rod, and a limiting plate. The outer walls of the two U-shaped frames are slidably installed on the outer surface of the dust-removing net plate through longitudinal springs. A plurality of the friction wheels are symmetrically and rotatably installed inside the U-shaped frame. Both ends of the reciprocating screw rod are fixedly installed on the side of the friction wheel close to the axis of the U-shaped frame. A plurality of the collecting plates penetrate and are movably installed on the outer wall of the reciprocating screw rod. The outer wall of the through rod penetrates and is fixedly installed inside a plurality of the collecting plates. Both sides of the limiting plate are fixedly installed inside the U-shaped frame.

[0014] According to the above technical solution, the top of the U-shaped frame is located on the movement track of the bottom of the sliding ring. The outer walls of several of the friction wheels are all in contact with the outer wall of the dust reduction net plate. The bottom of the limiting plate is slidably connected to the top of the collecting plate. During the downward movement of the sliding ring, the U-shaped frame will be pressed to slide downward synchronously along the outer wall of the dust reduction net plate. After the sliding ring resets, the U-shaped frame is reset by the elastic force of the spring. When the U-shaped frame drives the friction wheels to slide along the outer wall of the dust reduction net plate, it causes the friction wheels to generate frictional force and start to rotate. The friction wheels drive the reciprocating lead screw to rotate synchronously. When the reciprocating lead screw rotates, due to the limitation of the reciprocating spiral groove on its outer wall and the built-in blocks of several collecting plates, at this time, when the reciprocating lead screw rotates, it drives several collecting plates to reciprocate horizontally on its outer wall and reset by means of the limitation of the through rod. When the collecting plate slides horizontally along the bottom of the limiting plate, it will reciprocate horizontally scrape the outer wall of the dust reduction net plate.

[0015] According to the above technical solution, the anti-adhesion device further includes several elastic sheets and several impact columns. Several of the elastic sheets are symmetrically and fixedly installed between the top of the dust reduction net plate and the top inner wall of the U-shaped frame. One end of each of the several impact columns is symmetrically and fixedly installed at the concave surface of the elastic sheet. When the U-shaped frame moves downward, it drives the elastic sheets to move synchronously. After the bottom of the elastic sheet is restricted by the dust reduction net plate, it deforms and bends and stores energy. When the symmetrically distributed elastic sheets bend synchronously, they drive the impact columns to move away from each other synchronously. When the U-shaped frame resets, it causes the elastic sheets to drive the impact columns to suddenly reset and collide with each other to generate vibration.

[0016] The present invention provides a multi-station airtightness detection device for a globe valve. It has the following beneficial effects:

[0017] (1) Through the setting of the anti-offset device in the present invention, through the cooperation of the detection component, the connection component, the positioning rod, the air delivery component, the L-shaped plate, the limiting rail, the electric telescopic rod, the hydraulic gripper, the U-shaped pressing plate and the arc-shaped plate, the airtightness detection of multiple globe valves at multiple stations can be carried out synchronously, improving the use effect while enhancing the detection efficiency. At the same time, it improves the clamping stability of the hydraulic gripper for the globe valve and the downward pressure of the electric telescopic rod on the globe valve, ensuring good stability during the detection process of the globe valve to avoid misalignment, which may lead to errors in the detection results, and avoiding the need for staff to use a large amount of force to press the globe valve during the detection process, thereby increasing the labor intensity of the staff; at the same time, with the help of the U-shaped pressing plate, it is ensured that the globe valve clamped by the hydraulic gripper is always directly above the sealing component, avoiding the need for manual positioning between the globe valve and the sealing component during the detection process, resulting in an extended placement time of the globe valve and reducing the detection efficiency.

[0018] (2) Through the setting of the anti-pollution device, the present invention cooperates with the electric telescopic rod, L-shaped fixing plate, air extraction component, conveying pipe, penetrating plate, U-shaped transmission plate, hinge plate, rifled rod, sliding ring and dust reduction net plate. Relying on the penetrating plate to block the upper part of the air extraction component, it prevents the dirt pumped by the air extraction component from overflowing and flying everywhere when it has not entered the internal of the sand bag connected to the output end of the air extraction component. At the same time, it effectively expands the movement range of the air extraction component, ensures the cleanliness of the top surface of the driver, and avoids dirt overflowing into components such as positioning grooves or sealing components to contaminate the stop valve, thereby interfering with the detection accuracy. At the same time, it prompts the dust reduction net plate to rotate and adsorb the dust floating around the driver, avoiding the dust from flying and scattering onto the surfaces such as the stop valve or detection instrument, preventing the overall maintenance difficulty of the equipment from increasing and shortening the service life of the equipment.

[0019] (3) Through the setting of the anti-adhesion device, the present invention cooperates with the sliding ring, U-shaped frame, friction wheel, reciprocating screw rod, collection plate, penetrating rod, limiting plate, elastic piece and impact column. Relying on the collection plate to scrape and centrally collect the dirt adsorbed on the surface of the dust reduction net plate, and the U-shaped frame effectively expands the scraping range of the collection plate during the movement process, effectively avoiding the surface of the dust reduction net plate from becoming saturated due to excessive adsorption of dirt, preventing the adsorption force of the dust reduction net plate from decreasing after saturation and causing the dirt to detach again and attach to the surface of the stop valve. At the same time, relying on the vibration force to reduce the adhesion strength of the dirt on the surface of the dust reduction net plate, facilitating the collection plate to scrape and collect, preventing the dirt from solidifying after long-term attachment and being difficult to scrape off, and improving the scraping and collection effect of the collection plate to a certain extent.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0030] Please refer to Figure 1 - Figure 8 In one embodiment of the present invention: A multi-station airtightness detection device for a stop valve includes a device main body 1. A driver 2 is provided at the top of the device main body 1. A number of positioning grooves are equidistantly opened at the top of the driver 2. A sealing assembly 21 is provided inside the positioning grooves of the driver 2. An inflator 3 is provided at the center of the top of the driver 2. A hydraulic telescopic column 31 is provided on the outer wall of the inflator 3;

[0031] Anti-offset devices 4 corresponding to the number of positioning grooves and in one-to-one correspondence are provided at the edge of the top of the driver 2. An anti-pollution device 5 is provided inside the anti-offset device 4. An anti-adhesion device 6 is provided inside the anti-pollution device 5;

[0032] The anti-offset device 4 includes a detection assembly 41. The bottom of the detection assembly 41 is fixedly installed at the edge of the top of the driver 2. A connection assembly 42 is fixedly installed on the side of the detection assembly 41 close to the center of the driver 2. A positioning rod 43 is fixedly installed on the edge of the side of the detection assembly 41 close to the center of the driver 2. The end of the positioning rod 43 close to the center of the driver 2 penetrates and is slidably installed with a gas transmission assembly 44. An L-shaped plate 45 is fixedly installed at the edge of the top of the device main body 1. A limiting rail 46 is fixedly installed at the top of the inner wall of the L-shaped plate 45. An electric telescopic rod 47 is slidably installed inside the limiting rail 46. The bottom of the telescopic end of the electric telescopic rod 47 is fixedly installed with a hydraulic gripper 48. A U-shaped pressing plate 49 is fixedly installed on the side of the hydraulic gripper 48 close to the L-shaped plate 45. An arc-shaped panel 410 is fixedly installed on the outer wall of the positioning rod 43.

[0033] The gas transmission component 44 is connected to the inflator 3 through a hose. The side of the gas transmission component 44 close to the inflator 3 is fixedly installed at the telescopic end of the hydraulic telescopic column 31. The top arc surface of the arc panel 410 is located on the movement track of the bottom of the U-shaped pressing plate 49. Through the above cooperation, the airtightness detection of multiple stop valves at multiple workstations is carried out synchronously, improving the use effect and the detection efficiency. At the same time, the clamping stability of the hydraulic gripper 48 on the stop valve and the downward pressure of the electric telescopic rod 47 on the stop valve are improved, ensuring good stability during the detection of the stop valve and avoiding misalignment, which may lead to errors in the detection results, and avoiding the need for workers to use greater force to press the stop valve during the detection process, thus increasing the labor intensity of the workers. Through the above cooperation, with the help of the U-shaped pressing plate 49, it is ensured that the stop valve clamped by the hydraulic gripper 48 is always directly above the sealing component 21, avoiding the need for manual positioning between the stop valve and the sealing component 21 during the detection process, resulting in an extended placement time of the stop valve and a reduced detection efficiency.

[0034] When in use, put the stop valve into the top positioning groove of the driver 2, and the bottom of the stop valve is tightly connected with the sealing component 21, and the hydraulic telescopic column 31 is started at the same time. The telescopic end of the hydraulic telescopic column 31 pushes the gas delivery component 44 to slide along the top of the driver 2. At the same time, the gas delivery component 44 will slide along the outer wall of the positioning rod 43 for linear positioning during the sliding process. When one end of the gas delivery component 44 is connected with the stop valve, it will push the stop valve to move in the direction close to the L-shaped plate 45. Since the sealing component 21 is movably arranged inside the positioning groove, the stop valve drives the sealing component 21 to slide synchronously along the inside of the positioning groove until the other end of the stop valve is connected with the connecting component. The interface of 42 is connected, and the electric telescopic rod 47 is started. The telescopic end of the electric telescopic rod 47 drives the hydraulic clamp 48 to move downward. When the hydraulic clamp 48 contacts the top of the stop valve, the clamping distance is automatically adjusted to tightly clamp the stop valve. The inflator 3 inputs the detection gas into the gas delivery component 44 through the hose, and the gas delivery component 44 delivers gas to the inside of the stop valve. The pressure is monitored by the detection component 41 to determine whether the air tightness of the stop valve occurs. After the detection is completed, the hydraulic clamp 48 releases the clamp first, and the gas delivery component 44 pulls the stop valve and the sealing component 21 to reset. At this time, the electric telescopic rod 47 clamps the stop valve through the hydraulic clamp 48. The stop valve is held to move upward and detach from the sealing component 21, and the electric telescopic rod 47 slides along the inner side of the limit rail 46 toward the positive direction of the device body 1 to facilitate the staff to take the stop valve, and then the electric telescopic rod 47 slides to reset, and repeats this process. Through the above cooperation, the air tightness detection of multiple stop valves in multiple stations can be carried out simultaneously, which improves the use effect and the detection efficiency, and at the same time improves the clamping stability of the hydraulic clamp 48 on the stop valve and the downward pressure of the electric telescopic rod 47 on the stop valve, so as to ensure the good stability of the stop valve during the detection process, avoid the occurrence of misalignment and thus cause errors in the detection results, and avoid the need for staff to Using a greater force to press the stop valve increases the labor intensity of the staff; when the hydraulic clamp 48 moves downward, it drives the U-shaped pressure plate 49 to move synchronously. During the vertical downward movement of the U-shaped pressure plate 49, its own arc surface will contact the arc surface of the arc panel 410 to generate a resistance force. At this time, the U-shaped pressure plate 49 slides vertically downward along the vertical surface of the arc panel 410. Through the above cooperation, with the help of the U-shaped pressure plate 49, the stop valve clamped by the hydraulic clamp 48 is always directly above the sealing component 21, avoiding the need for manual positioning between the stop valve and the sealing component 21 during the detection process, resulting in prolonged placement of the stop valve and reduced detection efficiency.

[0035] See also Figure 1 - Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-pollution device 5;

[0036] The anti-pollution device 5 includes an L-shaped fixing plate 51, an air extraction assembly 52, a delivery pipe 53, and a through plate 54. The bottom of the L-shaped fixing plate 51 is fixedly installed on the fixed end of the electric telescopic rod 47 near one side of the L-shaped plate 45. The bottom of the air extraction assembly 52 is fixedly installed on the bottom inner wall of the L-shaped fixing plate 51. The top of the delivery pipe 53 penetrates and is fixedly installed at the bottom of the air extraction assembly 52. The through plate 54 is slidably installed inside the L-shaped plate 45 through a spring. The bottom of the through plate 54 is fixedly installed on the top of the L-shaped fixing plate 51. When the electric telescopic rod 47 slides horizontally inside the limit rail 46, it drives the L-shaped fixing plate 51 to move synchronously. Through the above cooperation, the through plate 54 is relied on to shield the upper part of the air extraction assembly 52, preventing the dirt pumped by the air extraction assembly 52 from overflowing and flying everywhere when it has not entered the internal of the sandbag connected to the output end of the air extraction assembly 52. At the same time, the moving range of the air extraction assembly 52 is effectively expanded, ensuring the cleanliness of the top surface of the driver 2, and avoiding the dirt overflowing into components such as the positioning groove or the sealing assembly 21 and polluting the stop valve, thereby interfering with the detection accuracy.

[0037] The anti-pollution device 5 further includes a U-shaped transmission plate 55, a hinge plate 56, a rifled rod 57, a sliding ring 58, and a number of dust reduction mesh plates 59. One end of the bottom of the U-shaped transmission plate 55 is fixedly installed on the top of the through plate 54. The other end of the U-shaped transmission plate 55 is provided with a U-shaped groove. The top of the hinge plate 56 is hinged inside the U-shaped groove of the U-shaped transmission plate 55. The bottom of the rifled rod 57 is rotatably installed on the top of the driver 2. The inside of the sliding ring 58 penetrates and is threadedly connected to the outer wall of the rifled rod 57. A number of dust reduction mesh plates 59 are all fixedly installed on the outer wall of the rifled rod 57.

[0038] A torsion spring is provided between the top of the hinge plate 56 and the U-shaped transmission plate 55. The outer wall of the sliding ring 58 is hinged to the bottom of the hinge plate 56. A number of dust reduction mesh plates 59 are equidistantly distributed on the outer wall of the rifled rod 57. Through the above cooperation, the dust reduction mesh plates 59 are prompted to rotate and adsorb the dust floating around the driver 2, avoiding the dust flying and scattering onto the surfaces of the stop valve or the detection instrument, etc., and preventing the overall maintenance difficulty of the equipment from increasing and shortening the service life of the equipment.

[0039] During use, when the electric telescopic rod 47 slides horizontally inside the limit rail 46, it drives the L-shaped fixing plate 51 to move synchronously. The L-shaped fixing plate 51 drives the air extraction assembly 52 to move synchronously, and the air extraction assembly 52 drives the conveying pipe 53 to move synchronously. After the air extraction assembly 52 is started, it absorbs dirt particles or air ash within its moving range through the conveying pipe 53. At the same time, the L-shaped fixing plate 51 pulls the penetrating plate 54 to slide synchronously along the inside of the L-shaped plate 45. When the electric telescopic rod 47 resets, the above structures reset synchronously and repeat this process. Through the above cooperation, relying on the penetrating plate 54 to block the upper part of the air extraction assembly 52, it prevents the dirt pumped by the air extraction assembly 52 from overflowing and flying everywhere before entering the yarn bag connected to the output end of the air extraction assembly 52. At the same time, it effectively expands the moving range of the air extraction assembly 52, ensures the cleanliness of the top surface of the driver 2, and avoids dirt overflowing into components such as the positioning groove or the sealing assembly 21 and polluting the stop valve, thereby interfering with the detection accuracy; when the penetrating plate 54 moves horizontally, it pulls the U-shaped transmission plate 55 to move synchronously. The U-shaped groove of the U-shaped transmission plate 55 drives the hinge plate 56 to move synchronously. The bottom of the hinge plate 56 is restricted by the sliding ring 58, causing its hinge shaft to start rotating. At this time, the hinge plate 56 pushes the sliding ring 58 to slide downward along the outer wall of the rifled rod 57 with the hinge shaft as the axis. When the sliding ring 58 slides, it drives the threaded rifled rod 57 to rotate on its own axis on the top of the driver 2. The rifled rod 57 drives the dust reduction net plate 59 to rotate. Through the above cooperation, the dust reduction net plate 59 rotates and adsorbs the dust floating around the driver 2, avoiding the dust flying onto the surfaces of the stop valve or the detection instrument, etc., and preventing the overall maintenance difficulty of the equipment from increasing and shortening the service life of the equipment.

[0040] Please refer to Figure 1 - Figure 8 Based on the above embodiments, in another embodiment of the present invention, an anti-adhesion device 6 is further included;

[0041] The anti-adhesion device 6 includes a U-shaped frame 61, a plurality of friction wheels 62, a reciprocating screw rod 63, a plurality of collecting plates 64, a penetrating rod 65 and a limiting plate 66. The outer walls of the two U-shaped frames 61 are slidably installed on the outer wall surface of the dust reduction net plate 59 through longitudinal springs. A plurality of friction wheels 62 are symmetrically and rotatably installed inside the U-shaped frame 61. Both ends of the reciprocating screw rod 63 are fixedly installed on the side of the friction wheel 62 close to the axis of the U-shaped frame 61. A plurality of collecting plates 64 are internally penetrated and movably installed on the outer wall of the reciprocating screw rod 63. The outer wall of the penetrating rod 65 is penetrated and fixedly installed inside a plurality of collecting plates 64. Both sides of the limiting plate 66 are fixedly installed inside the U-shaped frame 61.

[0042] The top of the U-shaped frame 61 is located on the movement track of the bottom of the sliding ring 58. The outer walls of a number of friction wheels 62 are all in contact with the outer wall of the dust-removing net plate 59. The bottom of the limiting plate 66 is slidably connected to the top of the collecting plate 64. Through the above cooperation, the collecting plate 64 is relied on to scrape and centrally collect the dirt adsorbed on the surface of the dust-removing net plate 59. And during the movement of the U-shaped frame 61, the scraping range of the collecting plate 64 is effectively enlarged, effectively avoiding the surface of the dust-removing net plate 59 from becoming saturated due to excessive adsorption of dirt, preventing the adsorption force of the dust-removing net plate 59 from decreasing after saturation, and preventing the dirt from detaching again and attaching to the surface of the stop valve.

[0043] The anti-attachment device 6 further includes a number of elastic sheets 67 and a number of impact columns 68. A number of elastic sheets 67 are symmetrically and fixedly installed between the top of the dust-removing net plate 59 and the top inner wall of the U-shaped frame 61. One ends of a number of impact columns 68 are symmetrically and fixedly installed at the concave surfaces of the elastic sheets 67. Through the above cooperation, the attachment force of the dirt on the surface of the dust-removing net plate 59 is reduced by relying on the vibration force, facilitating the scraping and collection by the collecting plate 64, preventing the phenomenon that the dirt is solidified after long-term attachment and thus difficult to scrape, and improving the scraping and collection effect of the collecting plate 64 to a certain extent.

[0044] During use, when the sliding ring 58 moves downward, it will press the U-shaped frame 61 to slide downward synchronously along the outer wall of the dust-removing mesh plate 59. After the sliding ring 58 resets, the U-shaped frame 61 resets by the elastic force of the spring. When the U-shaped frame 61 drives the friction wheel 62 to slide along the outer wall of the dust-removing mesh plate 59, it causes the friction wheel 62 to generate frictional force and start to rotate. The friction wheel 62 drives the reciprocating lead screw 63 to rotate synchronously. When the reciprocating lead screw 63 rotates, due to the limitation of the reciprocating spiral groove on its outer wall and the built-in blocks of several collecting plates 64, at this time, when the reciprocating lead screw 63 rotates, it drives several collecting plates 64 to reciprocate horizontally on its outer wall and reset by means of the limit of the through rod 65. When the collecting plate 64 slides horizontally along the bottom of the limiting plate 66, it will reciprocate horizontally scrape the outer wall of the dust-removing mesh plate 59. Through the above cooperation, the dirt adsorbed on the surface of the dust-removing mesh plate 59 is scraped and centrally collected by the collecting plate 64, and the scraping range of the collecting plate 64 is effectively enlarged during the movement of the U-shaped frame 61, effectively preventing the surface of the dust-removing mesh plate 59 from becoming saturated due to excessive adsorption of dirt, preventing the adsorption force of the dust-removing mesh plate 59 from decreasing after saturation, and preventing the dirt from detaching again and adhering to the surface of the stop valve; when the U-shaped frame 61 moves downward, it drives the elastic piece 67 to move synchronously. After the bottom of the elastic piece 67 is restricted by the dust-removing mesh plate 59, it deforms and bends and stores energy. When the symmetrically distributed elastic pieces 67 bend synchronously, they drive the impact columns 68 to move away from each other synchronously. When the U-shaped frame 61 resets, it causes the elastic piece 67 to drive the impact columns 68 to suddenly reset and collide with each other to generate vibration. Through the above cooperation, the adhesion force of the dirt on the surface of the dust-removing mesh plate 59 is reduced by the vibration force, which is convenient for the collecting plate 64 to scrape and collect, preventing the dirt from solidifying after long-term adhesion and being difficult to scrape, and improving the scraping and collecting effect of the collecting plate 64 to a certain extent.
