[0015] A control method for an intelligent adaptive pneumatic actuator control device, the control method comprising the following steps: When the breathable net needs to be cleaned, the electric hydraulic rod is controlled to extend at a variable telescopic speed, and the electric hydraulic rod controls the connecting frame to move downward. The process of the connecting frame moving promotes the rotation rod restricted by the pin shaft to rotate. Since the shielding cover, the extension plate, and the vertical rod are guided and restricted by the first linear bearing, the rotation process of the rotating rod controls the shielding cover on the front side to move downward and the shielding cover on the rear side to move upward. When the shielding cover on the rear side moves, the vertical rod is controlled to move upward through the extension plate. During the movement of the vertical rod, the gas in the upper air storage chamber in the connecting cylinder is squeezed and transferred to the piston frame through the connecting pipe. The increased air pressure in the lower air storage chamber in the piston frame controls the first piston plate to move upward. At this time, the first piston plate controls the piston cylinder to move upward through the first piston rod. The piston cylinder moves upward in the shielding cover as the shielding cover on the rear side moves to the shielding breathable net. During the movement of the shielding cover, the sliding block and the push plate are used to push the stabilized circular plate and the contact plate upward. When the contact plate and the circular plate move upward, the second piston rod and the second piston plate are used to squeeze the gas on the upper side of the piston cylinder. When the gas pressure in the upper gas storage chamber in the piston cylinder reaches a preset value, the gas is discharged through the one-way pressure relief valve, the air outlet pipe and the air outlet plate. The discharged high-pressure gas is blown from the inside to the outside on the surface of the breathable net, thereby realizing the recoil cleaning of the debris adhered to the outside of the breathable net. Due to the non-fixed extension and retraction speed of the electric hydraulic rod, the moving speed of the rotating rod, the shielding cover and the vertical rod is uncertain, which leads to different gas speeds entering the lower air storage chamber in the piston frame. Moreover, due to the limited size of the air outlet hole, the upward movement speed of the first piston plate and the first piston rod will change according to the extension and retraction speed of the electric hydraulic rod, so that the air outlet plate will be in different positions in the shielding cover when discharging gas multiple times, so that the air outlet plate can blow and clean the breathable net over a larger range and at multiple angles.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, the rotating rod mechanism of the electric hydraulic rod can accurately control the two shielding covers to be located at the upper and lower sides respectively, ensuring that there is always an air permeable net in a ventilation and heat dissipation state, which not only ensures the heat dissipation efficiency, but also provides the possibility for realizing automatic cleaning of the air permeable net; while the shielding cover moves upward, the sliding block and the push plate work together to push the circular plate and the second piston plate upward, and the function of the second piston plate is to compress the gas in the upper air storage chamber in the piston cylinder to a preset air pressure threshold, and then the gas is discharged through the one-way pressure relief valve and blown to the side of the air permeable net located in the control cabinet through the air outlet plate, so that the shielding cover is effectively The shielding effect ensures that the gas can only flow toward the outside of the control cabinet, thereby preventing dust and debris from being blown into the interior of the control cabinet while cleaning the air mesh, significantly improving the safety of the cleaning process and ensuring the overall ventilation and heat dissipation effect of the equipment; in this way, the dust and debris on the air mesh are effectively blown off, detached from the air mesh and fall, and will not enter the control cabinet, thus achieving automatic cleaning of the air mesh and avoiding the internal contamination and operational risks of the equipment caused by traditional manual wiping, which not only improves the maintenance efficiency of the equipment, but also ensures the reliability and safety of the equipment in long-term operation.

[0017] 2. In the present invention, through the combination of the electric hydraulic rod and the rotating rod, the device can accurately control the sliding of the shielding cover in the vertical direction. The non-fixedness of the extension and retraction speed of the electric hydraulic rod brings about the uncertainty of the moving speed of the shielding cover and the vertical rod. This dynamic change makes the gas flow rate entering the lower air storage chamber in the piston frame diversified; due to the size limitation of the air outlet, the upward movement speed of the first piston plate and the first piston rod will be adaptively adjusted with the extension and retraction speed of the electric hydraulic rod. This design enables the air outlet plate to reach different positions inside the shielding cover when discharging gas. The multi-position change of the air outlet plate makes the cleaning coverage area of ​​the air permeable net wider, ensuring the comprehensive cleaning of the air permeable net. The different positions of the air outlet plate provide multi-angle blowing cleaning, enhance the cleaning effect, and effectively remove dust and debris on the air permeable net; through the flexible control of the electric hydraulic rod and the dynamic position change of the air outlet plate, a large range and multi-angle blowing cleaning of the air permeable net is achieved, which not only improves the cleaning efficiency of the air permeable net, but also ensures the uniformity and thoroughness of the cleaning process, thereby improving the overall performance and reliability of the equipment.

DETAILED DESCRIPTION

[0020] 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 described embodiments 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.

[0021] Please see attached Figure 1 -Attached Fig.11The present invention provides a technical solution: an intelligent adaptive pneumatic actuator control device, comprising a control cabinet 1, a control door 2 is hinged on the front of the control cabinet 1, two air-permeable nets 3 are penetrated on the right side of the control cabinet 1, two shielding covers 4 are slidably connected to the right side of the inner wall of the control cabinet 1 at the position corresponding to the air-permeable net 3, and the left sides of the two shielding covers 4 are fixedly connected to a rotating adjustment device 5 arranged in the control cabinet 1, and the two shielding covers 4 are connected to an extension plate 6 on the side away from each other, and a sliding guide device 7 is fixedly connected under the extension plate 6. The side of the sliding guide device 7 is connected to a connecting pipe 9, the other end of the connecting pipe 9 is connected to a movable supporting device 10 fixedly connected to the control cabinet 1, an air outlet adjusting device 11 is fixedly connected to the movable supporting device 10, a second linear bearing 12 penetrating under the shielding cover 4 is slidably connected to the outside of the air outlet adjusting device 11, a sliding groove 15 is provided on the inner wall of the shielding cover 4, a sliding connecting device 14 slidably connected to the sliding groove 15 is fixedly connected to the top of the air outlet adjusting device 11, and an air outlet connecting device 13 is provided outside the air outlet adjusting device 11.

[0022] When the shielding cover 4 shields the air permeable net 3, it prevents the airflow from flowing into the control cabinet 1 through the air permeable net 3, and prevents dust and debris from flowing into the control cabinet 1 when being cleaned; Specifically, Figure 3-4 and Figure 7 As shown, the bottom end of the sliding guide device 7 is fixedly connected to a second fixed plate 8 arranged in the control cabinet 1, and the side of the air outlet adjustment device 11 is connected to an air intake pipe 16 that passes through the side of the shielding cover 4, and a one-way air intake valve 17 is provided outside the air intake pipe 16.

[0023] The one-way air intake valve 17 is used to flow gas into the piston cylinder 111 in one direction, so as to replenish the gas in the upper air storage chamber of the piston cylinder 111, and the gas in the piston cylinder 111 will not be discharged through the one-way air intake valve 17 when being squeezed; Specifically, Figure 3-5 As shown, the rotation adjustment device 5 includes a rotating rod 51, a pin 52 arranged in the control cabinet 1 is hinged at the middle position of the rotating rod 51, a first sliding hole 53 is opened on the side of the rotating rod 51, a connecting frame 54 is slidably connected in the first sliding hole 53, an electric hydraulic rod 55 is fixedly connected to the connecting frame 54, and the other end of the electric hydraulic rod 55 is fixedly connected to a first fixed plate 56 arranged in the control cabinet 1.

[0024] Second sliding holes 57 are provided at both ends of the side of the rotating rod 51 , and a connecting column 58 is slidably connected in the second sliding hole 57 . The connecting column 58 is located in the middle of the second sliding hole 57 , and the connecting column 58 is fixedly connected to the shielding cover 4 .

[0025] The rotating rod 51 is restricted by the pin 52 and can only rotate. When the electric hydraulic rod 55 controls the rotating rod 51 to rotate through the connecting frame 54, the rotating rod 51 will squeeze the connecting column 58 to move, thereby realizing the adjustment and control of the positions of the two shielding covers 4, and the connecting column 58 slides in the second sliding hole 57 with a slightly larger size, so that the rotating second sliding hole 57 can keep in contact with the connecting column 58 moving in the vertical direction; Specifically, Figure 6-7 As shown, the sliding guide device 7 includes a connecting tube 71 fixedly connected to the second fixed plate 8, a sliding plate 72 is slidably connected inside the connecting tube 71, a vertical rod 73 is fixedly connected to the sliding plate 72, the top of the vertical rod 73 is fixedly connected to the extension plate 6, and a first linear bearing 74 that penetrates the connecting tube 71 is slidably connected outside the vertical rod 73. The connecting tube 9 is connected to the air storage chamber located on the upper side of the sliding plate 72 in the connecting tube 71.

[0026] The first linear bearing 74 guides the vertical rod 73 to ensure that the extension plate 6 and the shielding cover 4 do not rotate when moving in the vertical direction, and can accurately and stably ensure the contact between the shielding cover 4 and the breathable net 3. The shielding cover 4 uses its vertical movement to control the sliding plate 72 to slide in the connecting tube 71, which squeezes the gas in the connecting tube 71, so that the gas is transferred into the movable support device 10, and the air pressure in the movable support device 10 is adjusted to a certain extent. Specifically, Figure 6-7 and Fig. 9 As shown, the movable support device 10 includes a piston frame 101 fixedly connected to the control cabinet 1, a first piston plate 102 is slidably connected inside the piston frame 101, a first piston rod 104 fixedly connected to the first piston plate 102 and fixedly connected to the air outlet adjustment device 11, a connecting sleeve 105 penetrating the piston frame 101 is slidably connected outside the first piston rod 104, a first elastic component 103 arranged in the piston frame 101 is fixedly connected below the first piston plate 102, an air outlet hole 106 is opened on the piston frame 101, and the piston frame 101 is connected to the connecting pipe 9.

[0027] The increased air pressure in the piston frame 101 will control the first piston plate 102 to move upward. The upward movement of the first piston plate 102 will squeeze the gas in the upper air storage chamber in the piston frame 101. The gas in the upper air storage chamber is discharged through the air hole 106. When the speed of the gas entering the lower air storage chamber in the piston frame 101 changes, the speed of the gas discharged from the upper air hole 106 is uncertain. Therefore, within a period of time, the upward movement amplitude of the first piston plate 102 and the first piston rod 104 will change with the gas flow rate. The first elastic component 103 is used to ultimately control the downward movement and reset of the first piston plate 102. Specifically, Figure 6-7As shown, the air outlet adjustment device 11 includes a piston cylinder 111 fixedly connected to the first piston rod 104, the piston cylinder 111 is slidably connected in the second linear bearing 12, a second piston plate 112 is slidably connected in the piston cylinder 111, a second piston rod 113 is fixedly connected to the second piston plate 112, the second piston rod 113 is outerly provided with a second elastic component 114 fixedly connected to the second piston plate 112 and the inner wall of the piston cylinder 111, the top end of the second piston rod 113 is connected to the sliding connection device 14, the piston cylinder 111 is connected to the air outlet connection device 13, and the piston cylinder 111 is connected to the air inlet pipe 16.

[0028] The second linear bearing 12 ensures that the piston cylinder 111 can stably slide vertically in the shielding cover 4. After the gas in the upper gas storage chamber of the piston cylinder 111 is squeezed to a certain pressure value, it will pass through the one-way pressure relief valve 132 and be discharged, so that the high-pressure gas enters the gas outlet pipe 131. Specifically, Figure 4 , Figure 6-7 and Fig.10 As shown, the air outlet connection device 13 includes an air outlet pipe 131 connected to the piston cylinder 111, the other end of the air outlet pipe 131 is connected to an air outlet plate 133, a one-way pressure relief valve 132 is provided outside the air outlet pipe 131, an extension rod 134 is fixedly connected under the air outlet plate 133, the bottom end of the extension rod 134 is fixedly connected to an elastic telescopic rod 135, and the bottom end of the elastic telescopic rod 135 is fixedly connected to a third fixed plate 136 provided outside the piston cylinder 111.

[0029] The elastic telescopic rod 135 allows the extension rod 134 and the air outlet plate 133 to move vertically relative to the piston cylinder 111 to a certain extent, so that the air outlet plate 133 can be squeezed and moved downward smoothly. The air outlet plate 133 can blow gas to the air permeable net 3 to clean the dust and debris adhered to the outer side of the air permeable net 3; Specifically, Figure 4 , Figure 8 and Fig.10 As shown, the sliding connection device 14 includes a circular plate 141 fixedly connected to the top end of the second piston rod 113, a contact plate 142 is fixedly connected to the outer arc surface of the circular plate 141 near the sliding groove 15, a push plate 143 is provided under the contact plate 142, a sliding block 144 slidably connected to the sliding groove 15 is fixedly connected to the side of the push plate 143, and a third elastic component 145 arranged in the sliding groove 15 is fixedly connected to the sliding block 144.

[0030] The sliding block 144 can move within the sliding groove 15 to a certain extent. The shielding cover 4 can push the contact plate 142 and the circular plate 141 to move through the sliding block 144. When the initial relative positions of the circular plate 141 and the shielding cover 4 are different, the sliding block 144 can still push the circular plate 141 by moving different distances. The third elastic component 145 applies elastic force to the sliding block 144, and uses the elastic force to ensure that the sliding block 144 will not shake at will, and can smoothly push the circular plate 141 to move, thereby realizing the control of the movement of the second piston rod 113.

[0031] A control method for an intelligent adaptive pneumatic actuator control device, the control method comprising the following steps: When the breathable net 3 needs to be cleaned, the electric hydraulic rod 55 is controlled to extend at a variable telescopic speed, and the electric hydraulic rod 55 controls the connecting frame 54 to move downward. The process of the connecting frame 54 moving promotes the rotation rod 51 restricted by the pin shaft 52 to rotate. Since the shielding cover 4, the extension plate 6, and the vertical rod 73 are guided and restricted by the first linear bearing 74, the rotation process of the rotating rod 51 controls the shielding cover 4 on the front side to move downward and the shielding cover 4 on the rear side to move upward. When the shielding cover 4 on the rear side moves, the vertical rod 73 is controlled to move upward through the extension plate 6. During the movement of the vertical rod 73, the gas in the upper air storage chamber in the connecting cylinder 71 is squeezed and transferred to the piston frame 101 through the connecting pipe 9. The increased air pressure in the lower air storage chamber in the piston frame 101 controls the first piston plate 102 to move upward. At this time, the first piston plate 102 controls the piston cylinder 111 to move upward through the first piston rod 104. As the shielding cover 4 at the rear side moves to the shielding breathable net 3, the piston cylinder 111 moves upward in the shielding cover 4. During the movement of the shielding cover 4, the sliding block 144 and the push plate 143 are used to push the stabilized circular plate 141 and the contact plate 142 upward. When the contact plate 142 and the circular plate 141 move upward, the second piston rod 113 and the second piston plate 112 are used to squeeze the gas on the upper side of the piston cylinder 111. When the gas pressure in the upper gas storage chamber in the piston cylinder 111 reaches a preset value, the gas is discharged through the one-way pressure relief valve 132, the air outlet pipe 131 and the air outlet plate 133. The discharged high-pressure gas is blown from the inside to the outside on the surface of the breathable net 3, so as to realize the recoil cleaning of the debris adhered to the outside of the breathable net 3. Since the extension and retraction speed of the electric hydraulic rod 55 is not fixed, the movement speeds of the rotating rod 51, the shielding cover 4 and the vertical rod 73 are uncertain, which leads to different gas speeds entering the lower air storage chamber in the piston frame 101. Since the size of the air outlet 106 is limited, the upward movement speed of the first piston plate 102 and the first piston rod 104 will change according to the extension and retraction speed of the electric hydraulic rod 55, so that the air outlet plate 133 will be in different positions in the shielding cover 4 when discharging gas multiple times, so that the air outlet plate 133 can blow and clean the breathable net 3 in a relatively large range and at multiple angles.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

10. A control method for an intelligent adaptive pneumatic actuator control device, characterized in that: According to an intelligent adaptive pneumatic actuator control device according to any one of claims 1 to 9, the control method comprises the following steps: When the air permeable net (3) needs to be cleaned, the electric hydraulic rod (55) is controlled to extend at a variable extension speed, and the electric hydraulic rod (55) controls the connecting frame (54) to move downward. The connecting frame (54) moves to push the rotating rod (51) restricted by the pin shaft (52) to rotate. Since the shielding cover (4), the extension plate (6), and the vertical rod (73) are guided and restricted by the first linear bearing (74), the rotating rod (51) controls the shielding cover (4) on the front side to move downward, and the shielding cover (4) on the rear side to move upward. 4) Move upward, when the rear shielding cover (4) moves, the extension plate (6) controls the vertical rod (73) to move upward, and during the movement of the vertical rod (73), the gas in the upper gas storage chamber in the connecting cylinder (71) is squeezed and transferred to the piston frame (101) through the connecting pipe (9), and the increased gas pressure in the lower gas storage chamber in the piston frame (101) controls the first piston plate (102) to move upward, and at this time, the first piston plate (102) controls the piston cylinder (111) to move upward through the first piston rod (104); The piston cylinder (111) moves upwards in the shielding cover (4) as the shielding cover (4) at the rear side moves to the shielding breathable net (3). During the movement of the shielding cover (4), the sliding block (144) and the push plate (143) are used to push the stabilized circular plate (141) and the contact plate (142) upwards. When the contact plate (142) and the circular plate (141) move upwards, the second piston rod (113) and the second piston plate (112) are used to squeeze the gas on the upper side of the piston cylinder (111). When the gas pressure in the upper gas storage chamber of the piston cylinder (111) reaches a preset value, the gas is discharged through the one-way pressure relief valve (132), the gas outlet pipe (131) and the gas outlet plate (133). The discharged high-pressure gas is blown from the inside to the outside onto the surface of the breathable net (3), thereby realizing recoil cleaning of debris adhered to the outer side of the breathable net (3). Since the extension and retraction speed of the electric hydraulic rod (55) is not fixed, the movement speeds of the rotating rod (51), the shielding cover (4) and the vertical rod (73) are uncertain, which in turn causes different speeds of gas entering the lower gas storage chamber in the piston frame (101). In addition, since the size of the air outlet hole (106) is limited, the upward movement speed of the first piston plate (102) and the first piston rod (104) will change according to the extension and retraction speed of the electric hydraulic rod (55), so that the air outlet plate (133) will be in different positions in the shielding cover (4) when exhausting gas multiple times, so that the air outlet plate (133) can blow and clean the air permeable net (3) over a relatively large range and at multiple angles.
