In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0027] Example 1

[0028] Reference Figures 1 to 3 , provides a schematic diagram of the overall structure of a pneumatic actuator positioner connection device for a power plant unit, such as Figure 1A pneumatic actuator positioner connection device for a power plant unit includes a connection mechanism 100, including a horseshoe plate 101, a mounting groove 102 arranged on the horseshoe plate 101, a movable groove 103 arranged on the horseshoe plate 101, a connection component 104 arranged in the movable groove 103, and a feedback arm 105 arranged on the connection component 104; a protection mechanism 200, including a protection component 201, a cleaning component 202 arranged on the protection component 201, and an adjustment component 203 arranged between the connection component 104 and the cleaning component 202 , wherein the staff can install and fix the horseshoe plate 101 to the valve stem coupling through the external bolt through the installation slot 102, and the feedback arm 105 will be rotatably installed on the positioner through the U-shaped plate. When the pneumatic actuator works to move the coupling up and down, the movable slot 103 will push the connecting component 104 and the feedback arm 105 to move, so that the connecting component 104 connected to the feedback arm 105 will rotate in a circle with the connection axis point between the feedback arm 105 and the positioner as the center, thereby feeding back the displacement information of the valve stem to the positioner for subsequent adjustment and control.

[0029] Specifically, the connecting component 104 includes a connecting bolt 104a arranged in the movable groove 103, a fixing screw 104b arranged on the connecting bolt 104a, a sleeve 104c arranged on the connecting bolt 104a, and a buffer pad 104d arranged between the sleeve 104c and the connecting bolt 104a; the movement trajectory of the connecting bolt 104a is adapted to the movable groove 103, and the connecting bolt 104a can be fixed to the feedback arm 105 by the fixing screw 104b when in use to avoid the situation where movement during the working process affects the feedback accuracy. The sleeve 104c will be in close contact with the movable groove 103 during operation, and the buffer pad 104d can absorb and buffer the vibration impact of the device. When the horseshoe plate 101 moves up and down so that the connecting component 104 rotates with the connection axis point of the feedback arm 105 and the positioner as the center, the connecting bolt 104a will move left and right in the movable groove 103 through the sleeve 104c to avoid the situation where the connecting component 104 is stuck during the arc movement process.

[0030] Furthermore, the protective component 201 includes a protective plate 201a arranged on the cleaning component 202, and a protective glass plate 201b arranged on the protective plate 201a, wherein the staff can fix the protective plate 201a to the frame of the pneumatic valve through the through hole on the protective plate 201a when working, so as to shield and protect the device during the working process, avoid direct exposure to the outside to cause collision damage affecting subsequent feedback control work, and increase the stability of the device. The protective glass plate 201b can facilitate the staff to check the working condition of the device when checking and maintaining the device without greatly affecting the protection performance.

[0031] Operation process: When the valve stem coupling moves, it will drive the horseshoe plate 101 to move up and down synchronously. During the movement, the connecting bolt 104a will be pushed together with the feedback arm 105 through the movable groove 103 to rotate in a circle with the feedback arm 105 and the positioner connection axis point, so that the displacement of the shaft rod is fed back to the positioner through the feedback arm 105. The actuator responds quickly, and the anti-vibration effect of the positioner feedback is improved, which reduces the vibration caused by the valve pipeline, avoids the use of universal joints or excessively long connecting rods to cause shaking that affects the feedback accuracy, and reduces the failure rate of the actuator. The protective component 201 will shield and protect the device position to avoid collision damage caused by exposure to the outside that affects the feedback work, thereby extending the service life of the device.

[0032] Example 2

[0033] Reference Figures 1 to 5 This embodiment is different from the first embodiment in that it also includes a cleaning component 202, including a cleaning piece 202a arranged on the protective plate 201a, and an indicator piece 202b arranged on the cleaning piece 202a. When the valve stem coupling moves to drive the feedback arm 105 to perform rotational feedback, the cleaning piece 202a and the indicator piece 202b will be driven to move synchronously, so that the protective glass plate 201b can be cleaned while the opening of the pneumatic valve can be displayed, which is convenient for personnel to check.

[0034] Specifically, the cleaning member 202a includes a shaft 202a-1 disposed on the adjustment component 203, a limit groove 202a-2 disposed on the protective plate 201a and adapted to the shaft 202a-1 in terms of motion trajectory, a flat gear 202a-3 disposed on the shaft 202a-1, a first cleaning wheel 202a-4 disposed on the adjustment component 203, a fixed plate 202a-5 disposed between the shaft 202a-1, a second cleaning wheel 202a-6 disposed on the fixed plate 202a-5, and tooth grooves 202a-7 disposed on both the first cleaning wheel 202a-4 and the second cleaning wheel 202a-6; the flat gear 202a-3 is provided with two groups, and the two groups of flat gears 202a-3 are respectively meshed with the corresponding tooth grooves 202a-7, and when the horseshoe plate 101 moves to drive the feedback arm 105 to move When working in circular rotation, the first cleaning wheel 202a-4 will be driven to move horizontally up and down on the protective plate 201a through the connecting component 104 according to the direction of arc rotation. The adjusting component 203 will be synchronously telescopically adjusted according to the change in the distance between the first cleaning wheel 202a-4 and the connecting component 104 during the movement of the first cleaning wheel 202a-4 to avoid jamming during operation. When the first cleaning wheel 202a-4 moves up and down, it will drive the fixed plate 202a-5 together with the second cleaning wheel 202a-6 to move through the shaft 202a-1, so that when the valve stem moves up and down to control the opening and closing of the pneumatic valve, the surfaces on both sides of the protective glass plate 201b are automatically cleaned together. There is no need for staff to manually clean the dust on the surface of the protective glass plate 201b for inspection when inspection is required, which is convenient for personnel to use.

[0035] Furthermore, the indicator 202b includes a pointer 202b-1 arranged on the fixed plate 202a-5, and an indicator plate 202b-2 arranged on the protective plate 201a. When the feedback arm 105 rotates and feedbacks to drive the first cleaning wheel 202a-4 and the second cleaning wheel 202a-6 to move to clean the surface of the protective glass plate 201b, the pointer 202b-1 will be driven to move synchronously through the fixed plate 202a-5. The pointer 202b-1 will accurately point to the distance value on the indicator plate 202b-2. The staff can accurately and intuitively observe the opening of the pneumatic valve outside the device, thereby increasing work efficiency and facilitating use by personnel.

[0036] The rest of the structure is the same as that of Example 1.

[0037] Operation process: When the feedback arm 105 rotates to perform feedback according to the displacement of the valve stem coupling, it will drive the cleaning member 202a to move up and down horizontally on the protective plate 201a, so that the first cleaning wheel 202a-4 and the second cleaning wheel 202a-6 can automatically clean the surface of the protective glass plate 201b to prevent dust accumulation from affecting people's vision. At the same time, it will drive the pointer 202b-1 to move synchronously. The staff can easily and accurately know the opening degree of the pneumatic valve at this time by pointing the pointer 202b-1 to the data on the indicator board 202b-2, which is convenient for personnel to use.

[0038] Example 3

[0039] Reference Figures 1 to 5 , this embodiment is different from the above embodiment in that it also includes an adjustment component 203, including a movable seat 203a arranged on the sleeve 104c, a fixed seat 203b arranged on the shaft 202a-1, a first bevel gear 203c arranged between the fixed seat 203b and the first cleaning wheel 202a-4, a first adjustment member 203d arranged between the fixed seat 203b and the movable seat 203a, a second adjustment member 203e arranged between the fixed seat 203b and the movable seat 203a, and a driving element 203f arranged on the sleeve 104c, wherein the first bevel gear 203c is movably mounted on the fixed seat 203b, and when the horseshoe plate 101 pushes the connecting component 104 together with the feedback arm 105 to rotate to perform feedback on the positioner, the first adjustment member 203d and the second adjustment member 203e are used to adjust the position of the first bevel gear 203c. 3e drives the first bevel gear 203c to rotate to drive the first cleaning wheel 202a-4 to rotate. When the first cleaning wheel 202a-4 rotates, it will drive the shaft 202a-1 to rotate through the corresponding tooth groove 202a-7 and the engagement with the flat gear 202a-3. When the shaft 202a-1 rotates, it will drive another set of flat gears 202a-3 to rotate, so as to drive the second cleaning wheel 202a-4 to rotate by engaging with the tooth groove 202a-7 on the second cleaning wheel 202a-4, so that when the first cleaning wheel 202a-4 rotates, it drives the second cleaning wheel 202a-6 to rotate together. When the first cleaning wheel 202a-4 and the second cleaning wheel 202a-6 are driven by the feedback arm 105 to rotate and move on the download protection plate 201a to perform cleaning work, they rotate together to increase the cleaning effect and cleaning efficiency during the working process.

[0040] Specifically, the first adjusting member 203d includes a limit block 203d-1 arranged on the fixed seat 203b, a transmission belt 203d-2 arranged between the limit blocks 203d-1, a bevel gear block 203d-3 arranged on the transmission belt 203d-2 and meshing with the first bevel gear 203c, a fixed block 203d-4 arranged on the transmission belt 203d-2, and a connecting rod 203d-5 arranged between the fixed block 203d-4 and the movable seat 203a. When the feedback arm 105 rotates to push the cleaning member 202a to move horizontally up and down on the protective plate 201a to perform cleaning work, the connecting rod 203d-5 will telescope left and right on the fixed seat 203b, which can ensure that the connecting component 104 is synchronously adjusted according to the change of the spacing when connected to the cleaning member 202a, so that the feedback arm 105 can always drive the cleaning member 202a to move during the rotation process to avoid jamming. At the same time, when the connecting rod 203d-5 moves on the fixed seat 203b, it will drive the transmission belt 203d-2 to move on the limit block 203d-1 through the fixed block 203d-4. During the movement of the transmission belt 203d-2, the bevel gear block 203d-3 will engage with the first bevel gear 203c to drive the first bevel gear 203c to rotate counterclockwise, thereby driving the first cleaning wheel 202a-4 to rotate. The spacing arrangement between the bevel gear blocks 203d-3 on the transmission belt 203d-2 is different from that of the first bevel gear 203c. When the transmission belt 203d-2 uses the bevel gear block 203d-3 to drive the first bevel gear 203c to rotate counterclockwise by one tooth, the subsequent bevel gear block 203d-3 does not continue to contact the first bevel gear 203c to continue to engage and drive it, thereby causing the first bevel gear 203c to stop rotating until the subsequent bevel gear block 203d-3 contacts the first bevel gear 203c again and drives it to rotate again.

[0041] Further, the second adjusting member 203e includes a rotating drum 203e-1 disposed on the driving element 203f, a plurality of movable rods 203e-2 disposed on the movable seat 203a and the fixed seat 203b, a connecting shaft 203e-3 disposed between the movable rods 203e-2, a second bevel gear 203e-4 disposed on the fixed seat 203b, and a belt 203e-5 drivingly connected to the second bevel gear 203e-4, the connecting shaft 203e-3 and the rotating drum 203e-1;The second bevel gear 203e-4 is meshed with the first bevel gear 203c. When the horseshoe plate 101 moves up and down to push the connecting component 104 and the feedback arm 105 to rotate for feedback work, the connecting component 104 will move left and right in the movable groove 103 synchronously during the up and down process of the horseshoe plate 101, so that the connecting component 104 and the feedback arm 105 can rotate synchronously under the push of the up and down movement of the horseshoe plate 101 to avoid jamming. When the connecting component 104 moves left and right in the movable groove 103, it will drive the driving element 203f to rotate, and the driving element 203f will drive the second bevel gear 203e-4 to rotate synchronously through the belt 203e-5, thereby 3e-4 meshes with the first bevel gear 203c and drives the first bevel gear 203c to rotate clockwise. The spacing of the bevel teeth on the second bevel gear 203e-4 is consistent with the spacing of the bevel tooth block 203d-3 on the transmission belt 203d-2. Therefore, after the second bevel gear 203e-4 drives the first bevel gear 203c to rotate one tooth clockwise, the subsequent bevel teeth of the second bevel gear 203e-4 do not continue to contact the first bevel gear 203c and are disengaged until the second bevel gear 203e-4 contacts the first bevel gear 203c again and drives it to rotate again. In addition, the bevel tooth block 203d-3 on the transmission belt 203d-2 and the bevel teeth on the second bevel gear 203e-4 are staggered, so that the transmission belt 203d-2 passes When the bevel gear block 203d-3 drives the first bevel gear 203c to rotate counterclockwise by one grid and then temporarily disengages from the first bevel gear 203c, the second bevel gear 203e-4 then meshes with the first bevel gear 203c and drives the first bevel gear 203c to rotate clockwise by one grid. Subsequently, the second bevel gear 203e-4 and the first bevel gear 203c temporarily disengage from the meshing state, and the transmission belt 203d-2 will mesh with the first bevel gear 203c again through the bevel gear block 203d-3 and drive it to continue rotating, thereby automatically driving the first cleaning wheel 202a-4 to rotate back and forth in a cycle when the feedback arm 105 rotates and feedbacks to drive the first cleaning wheel 202a-4 to move horizontally up and down on the protective plate 201a for cleaning. When the wheel 202a-4 rotates back and forth, the tooth groove 202a-7 and the flat gear 202a-3 are meshed to drive the second cleaning wheel 202a-6 to rotate together, which can further clean the dust remaining on the protective glass plate 201b to avoid the dust remaining and affecting the sight, and improve the cleaning effect. When the feedback arm 105 rotates and feedbacks, the movable rod 202e-2 will cooperate with the connecting shaft 202e-3 to extend and contract according to the change of the horizontal lateral spacing between the protective plate 201a and the connecting component 104, so as to always tension the position of the belt 202e-5, avoid the situation of loosening due to the shrinkage of the distance spacing or breaking due to the extension of the distance spacing, and ensure the normal transmission cleaning work of the device. ;

[0042] Furthermore, the driving element 203f includes a roller 203f-1 arranged on the sleeve 104c, and a guide plate 203f-2 arranged on the horseshoe plate 101; the movement trajectory of the roller 203f-1 is adapted to the guide plate 203f-2, when the horseshoe plate 101 follows the valve stem coupling to move up and down and drives the feedback arm 105 to perform rotation feedback through the connecting component 104, in order to ensure that the feedback arm 105 normally follows the horseshoe plate 101 to move up and down and rotate synchronously, the connecting component 104 is used to connect the feedback arm 105 to the feedback arm 105. Component 104 will move left and right in the movable groove 103 to prevent the device from getting stuck, and the starting roller 203d-1 will be in close contact with the guide plate 203f-2. When the connecting component 104 moves left and right in the movable groove 103, it will drive the roller 203-1 to roll back and forth on the guide plate 203f-2. During the rolling process, it will drive the rotating drum 203e-1 to be transmitted together, thereby driving the second bevel gear 203e-4 to rotate through the belt 203e-5 to drive the cleaning element 202 to further increase the cleaning effect.

[0043] The rest of the structure is the same as that of Example 2.

[0044] Operation process: When the feedback arm 105 rotates to perform feedback work according to the displacement of the valve stem coupling, in order to perform feedback and cleaning work normally without being stuck, the first adjustment member 203d and the second adjustment member 203e will extend and contract according to the change of the horizontal lateral spacing between the cleaning member 202 and the connecting component 104. The first adjustment member 103d will drive the transmission belt 203d-2 to engage with the first bevel gear 203c according to the adjustment of the extension and contraction, thereby driving the first cleaning wheel 202a-4 to rotate counterclockwise, and the connecting component 104 will also move in the movable groove 103. During the movement, the roller 203d-1 will be driven to roll on the guide plate 203f-2, thereby using the belt 203e-5 to drive the second bevel gear 203e-4 to rotate, so as to engage with the first bevel gear 203c and drive the first cleaning wheel 202a-4 to rotate clockwise. The transmission belt 203d-2 and the second bevel gear 203e-4 will alternately engage with the first bevel gear 203c in a cycle, thereby driving the first cleaning wheel 202a-4 to rotate back and forth, increasing the cleaning frequency and accuracy of the surface of the protective glass plate 201b, improving the cleaning effect, and making it easier for personnel to use.
