The triangular plate pulls down the upper end of the connecting rod through the last angle rotation, and the other end of the connecting rod is passively pushed outward. In this way, the first rigid pipe rotates around its upper end rotation connection point until the two corners of the connecting rod and the triangular plate are in the same straight line. At this time, the expansion angle is maximized to meet the need for air duct avoidance. Through the push-pull method of the triangular plate, the stroke of the electric push rod can be shortened, and an extra-long electric push rod should not be used, which saves installation space and reduces costs.

[0016] Refer to the attached Figure 1-5 A roving blowing and suction air duct extension device for a roving cleaning machine, wherein roving blowing and suction air ducts 2 are installed on both sides of a main body 1 of the roving cleaning machine, and the roving blowing and suction air ducts 2 include a first flexible pipe 21, a first rigid pipe 22, a second flexible pipe 23, a second rigid pipe 24 and an inward-retracting bracket 25. A horizontal support frame 11 is installed on both sides of the main body 1 of the roving cleaning machine, and the upper end of the first rigid pipe 22 is rotatably installed on the outer side of the horizontal support frame 11. The upper end of the first rigid pipe 22 is connected to the blowing and suction air outlets on both sides of the main body 1 of the roving cleaning machine through the first flexible pipe 21; the lower end of the first rigid pipe 22 is connected to the second rigid pipe 24 through the second flexible pipe 23. The inward-retracting bracket 25 includes an upper bracket 251, a lower bracket 252, and a tilting rod 253. The upper bracket 251 is installed at the lower end of the first rigid pipe 22, and the lower bracket 252 is installed at the second rigid pipe 24. The upper end of the tilting rod 253 is fixed on the upper bracket 251, the tilting rod 253 is tilted inwardly at a certain angle relative to the first rigid pipe 22, and the lower end of the tilting rod 253 is rotatably connected to the lower bracket 252. The outer sides of the horizontal support frames 11 on both sides are respectively installed with outreach devices 20, and the outreach devices 20 include an electric telescopic rod 201, a connecting rod 202, and a triangular plate 203. The rear end of the electric telescopic rod 201 is rotatably installed on the horizontal support frame 11 on the corresponding side of the main body 1 of the patrol cleaning machine, and one corner of the triangular plate 203 is located above the electric telescopic rod 201 and is rotatably installed on the horizontal support frame 11. The front telescopic end of the electric telescopic rod 201 is rotatably connected to a corner of the lower end of the triangular plate 203, and the last corner of the triangle is rotatably connected to the upper end of the connecting rod 202. The other end of the connecting rod 202 is rotatably connected to the middle upper position of the inner side of the first rigid pipe 22.

[0017] The first flexible pipe 21 and the second flexible pipe 23 are bellows-type hoses, which are designed to ensure that the pipes can bend and stretch without damage or leakage.

[0018] The first flexible duct 21, the first rigid duct 22, the second flexible duct 23, and the second rigid duct 24 are connected to form an air duct, and three such air ducts are designed on both sides of the main body 1 of the patrol cleaning machine, and the three air ducts are installed side by side. The outer side of the horizontal support frame 11 is rotatably connected to the inner upper end of the first rigid duct 22 of the three air ducts, the upper bracket 251 is connected to the lower end of the first rigid duct 22 of the three air ducts, and the lower bracket 252 is connected to the upper end of the second rigid duct 24 of the three air ducts. The upper bracket 251 and the lower bracket 252 are connected between the three air ducts by two inclined rods 253; the air ducts 2 on both sides of the three air ducts are connected to the external extension device 20 on the corresponding side. Normally, there are three air ducts on one side of the patrol cleaning machine. The air duct combination on both sides is a suction duct, and the air duct in the middle is a blowing duct. They are all existing technologies, and the present invention is briefly described.

[0019] The triangular plate 203 is provided with a V-shaped avoidance groove 2030 on one side close to the electric telescopic rod 201. The avoidance groove is designed to prevent the triangular plate and the electric telescopic rod from interfering with each other during operation, thereby ensuring safe and stable operation.

[0020] The front side or inner side of the second rigid pipe 24 at the middle front side of the three air ducts is equipped with an obstacle sensing photoelectric switch 204 facing the front side, and the rear side or inner side of the second rigid pipe at the middle rear side of the three air ducts is equipped with an obstacle sensing photoelectric switch 204 facing the front side; the inner side of the middle second rigid pipe of the three air ducts is equipped with an outward extension reset photoelectric switch 205 facing the inside. The obstacle sensing photoelectric switches on both sides are to ensure that the patrol cleaning machine senses the presence of the wiring robot in advance when it moves, so that the electric telescopic rod performs corresponding actions; the outward extension reset photoelectric switch is to ensure that the wiring robot passes through the inside of the air duct, and at the same time gives the electric telescopic rod signal, and then delays for a few seconds to control the outward extension device to retract the air duct, reset and continue working.

[0021] The main body of the patrol cleaning machine is installed above the spinning frame 3 so as to move forward and backward, and the air ducts 2 on both sides are respectively located on both sides of the spinning frame 3. This is a conventional design, and the present invention is briefly described.

[0022] When the present invention is used, the patrol cleaning machine carries the air ducts on both sides to patrol and clean above the spinning frame. During the operation and movement, the obstacle sensing photoelectric switch 204 on the side of the head senses the wiring robot 4 at a distance of about 0.5 meters. At this time, the electric telescopic rod shrinks and pulls back a rotation fulcrum of the triangular plate, so that the connecting rod and the other two rotation fulcrums of the triangular plate are in a straight line. The three air ducts are pushed outward together, and the first rigid pipe rotates around the rotation fulcrum of the horizontal support frame. The lower end swings outward with the second rigid pipe. During the swinging outward, the second rigid pipe is always in a drooping state, so that the three air ducts pass from the outside of the wiring robot 4. When the middle outward resetting photoelectric switch 205 detects the wiring robot 4, the electric telescopic rod starts to extend after 2-3 seconds. The setting of 2-3 seconds is to ensure that this time is enough for the patrol cleaning machine to pass the outside of the wiring robot 4 with the air duct. Of course, this time can be adjusted according to the actual moving speed of the patrol cleaning machine to meet different speed requirements; after the three air ducts are reset, the patrol cleaning machine continues to work.
