[0036] like Figure 2-8 , Embodiment 1 shown in 10-11: like Figure 2 As shown: it includes a pneumatic rust removal mechanism, which includes an annular mounting plate 1 and a fan-shaped air knife 2. The fan-shaped air knife 2 is coaxially mounted on one side of the annular mounting plate 1. The fan-shaped air knife 2 includes a first fan-shaped air knife 201 and a second fan-shaped air knife 202. The first fan-shaped air knife 201 and the second fan-shaped air knife 202 have the same structure and are both set to six. The six first fan-shaped air knives 201 and the six second fan-shaped air knives 202 are replaced in sequence and arranged in an annular array. The sides of the multiple first fan-shaped air knives 201 and the second fan-shaped air knives 202 can be sealed and fitted to form an annular structure, and the multiple first fan-shaped air knives 201 and the second fan-shaped air knives 202 are adjustable in position in the central radial direction, which is suitable for high-strength jet rust removal of metal structures with different radial widths; like Figure 10-11As shown, the first fan-shaped air knife 201 and the second fan-shaped air knife 202 both include a main shell 2011 and a sealing cover 2012. The inner cavity of the main shell 2011 is a stepped cavity 3 from wide to narrow from the outer end to the inner end. The narrow end of the stepped cavity 3 is connected to an inclined air outlet cavity 4, and the air outlet cavity 4 passes through the inner end of the main shell 2011. The width of the air outlet cavity 4 is opened along the width direction of the main shell 2011 to the edge of the main shell 2011 but does not pass through.

The outer end of the main housing 211 is provided with an air inlet 5 connected to the stepped cavity 3, and the air inlet 5 is externally connected to a high-pressure air source. After the high-pressure air source enters the stepped cavity 3, it is compressed again and obliquely ejected from the air outlet cavity 4 to form a wind knife state. Under the action of high-pressure wind, rust stains on the surface of the metal structure can be effectively removed; like Figure 4 As shown: six first fan-shaped air knives 201 are grouped into three adjacent groups, which are divided into two groups. Six first linear slide grooves 9 are radially opened on the annular mounting plate 1. The six first linear slide grooves 9 are arranged in an annular array with the axis of the annular mounting plate 1 as the center, and are respectively arranged in the middle of the lower part of the six first fan-shaped air knives 201. The six first fan-shaped air knives 201 are respectively slidably installed on the six first linear slide grooves 9. An extension plate 10 is provided in the middle between two adjacent first fan-shaped air knives 201 in each group. The extension plate 10 is connected to the outer side of the annular mounting plate 1 and is an integrated structure with the annular mounting plate 1. A second linear slide groove 11 is radially opened on the extension plate 10 along the annular mounting plate 1. A slider 12 is slidably installed on the second linear slide groove 11. Each group of three first fan-shaped air knives 201 and two sliders 12 are arranged in sequence between adjacent two. A connecting rod 13 is hingedly connected, and two first automatic telescopic rods 14 are fixedly installed on the outer side of the annular mounting plate 1. The two first automatic telescopic rods 14 correspond to the first fan-shaped air knives 201 in the middle of the two groups of three first fan-shaped air knives 201 respectively. The axis of the first automatic telescopic rod 14 is parallel to the sliding direction of the corresponding first fan-shaped air knife 201, and the output end of the first automatic telescopic rod 14 is fixedly connected to the corresponding first fan-shaped air knife 201. The first automatic telescopic rod 14 includes but is not limited to the use of a cylinder and an electric telescopic rod.

This state is the maximum inner diameter channel of the pneumatic rust removal mechanism, which is used for rust removal of metal structures with large diameter width; like Figure 3 As shown: the first automatic telescopic rod 14 pulls the first fan-shaped air knife 201 to move outward, and the second automatic telescopic rod 15 pushes the second fan-shaped air knife 202 to move inward, until the inner end sides of the two adjacent second fan-shaped air knives 202 are in contact with each other. This state is the minimum inner diameter channel of the pneumatic rust removal mechanism, which is used for rust removal of metal structures with small diameter width. When the position of the fan-shaped air knife 2 is adjusted, the metal structure is positioned close to the output end of the fan-shaped air knife 2 to ensure high-strength contact between the gas and the metal structure, thereby achieving a good rust removal effect. In addition, the inner end sides of the six second fan-shaped air knives 202 are in contact with each other, or the sides of the first fan-shaped air knife 201 and the second fan-shaped air knife 202 are in contact with each other to form an annular channel, which can fully cover the outer surface of the metal structure and remove rust in all directions; like Figure 7 As shown: an air valve 6 is installed on the air inlet 5 of the first fan-shaped air knife 201, and the input ends of the air valves 6 of the three first fan-shaped air knives 201 in each group are connected in series in sequence through the pipeline 16, and an air inlet is opened on the air valve 6 of one first fan-shaped air knife 201 for connecting to an external high-pressure air source, that is, two groups of first fan-shaped air knives 201 have two air inlets as input ports for connecting to an external high-pressure air source, thereby reducing the number of input ports; like Figure 8 As shown: an air valve 6 is also installed on the air inlet 5 of the second fan-shaped air knife 202, and the input ends of the air valves 6 of the six second fan-shaped air knives 202 are connected in series in sequence through the pipeline 16, and an air inlet is opened on the air valve 6 of one second fan-shaped air knife 202 for connecting to an external high-pressure air source, that is, the six second fan-shaped air knives 202 use one air inlet as the input port to connect to the external high-pressure air source, thereby reducing the number of input ports, and the pipeline 16 adopts a high-pressure hose with deformation ability to adapt to the change of the position of the fan-shaped air knife 2, and the air valve 6 is installed on the air inlet 5 of the fan-shaped air knife 2, so as to realize independent control of the gas output of multiple fan-shaped air knives 2, thereby realizing local rust removal of the metal structure.
