[0041] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0042] like Figures 1 to 12 A drone blowing device for factory steel beams is shown, which includes: a drone 1, a blowing device 2 arranged at the bottom of the drone 1, a rotating drive device 3, a monitoring system and a control system, wherein the rotating drive device 3 drives the blowing device 2 to rotate; the rotating drive device 3 can be set to rotate the blowing device 2 according to the actual blowing position height and other conditions to adapt to the actual height, so as to avoid the air outlet of the blowing device 2 being unable to reach the top surface of the steel beam when the upper space is relatively small.

[0043] The purging device 2 includes a mounting plate 2-1, two groups of conveying devices 2-2 and two groups of purging mechanisms 2-3. The two groups of conveying devices 2-2 are respectively arranged on both sides of the bottom surface of the mounting plate 2-1. The two groups of purging mechanisms 2-3 are respectively arranged on the two groups of conveying devices 2-2, and the two groups of purging mechanisms 2-3 are symmetrically arranged. The two groups of conveying devices 2-2 respectively drive the two groups of purging mechanisms 2-3 to move toward or relative to each other. The symmetrical arrangement plays a role in offsetting the reverse twist, thereby increasing the air flow rate to generate jet kinetic energy and improving efficiency. The conveying device 2-2 adjusts the distance between the two groups of purging mechanisms 2-3 according to the distance between the two groups of steel beams to be purged, so that the purging device 2 can purge two groups of steel beams at the same time, thereby improving the purging efficiency.

[0044] The purge mechanism 2-3 includes a purge air duct 2-3-1, a duct fan 2-3-2 and an air outlet device 2-3-3. The upper end of the purge air duct 2-3-1 is an air inlet, and the duct fan 2-3-2 is fixedly arranged at the air inlet of the purge air duct 2-3-1. The lower end of the purge air duct 2-3-1 is an air outlet, and the air outlet device 2-3-3 is fixedly arranged at the air outlet of the purge air duct 2-3-1. The control system is electrically connected to the drone 1, the conveying device 2-2, the duct fan 2-3-2, the rotating drive device 3 and the monitoring system respectively.

[0045] Furthermore, the rotation drive device 3 includes two groups of rotation drive motors 3-1 and two groups of rotating shafts 3-2. The two groups of rotating shafts 3-2 are arranged in parallel and rotate on the front and rear sides of the bottom of the fixing plate 1-1 at the bottom of the drone 1. The two groups of rotation drive motors 3-1 are coaxially arranged on one side of the two groups of rotating shafts 3-2, and the output end of the rotation drive motor 3-1 is fixedly connected to one end of a corresponding group of rotating shafts 3-2; the rotation drive motor 3-1 drives the rotating shaft 3-2 to rotate.

[0046] On both sides of the rotating shaft 3-2, connecting rods 3-3 are fixedly arranged. The bottom ends of the connecting rods 3-3 are hinged to the top surface of the mounting plate 2-1. The rotating drive motor 3-1 drives the rotating shaft 3-2 to rotate, thereby realizing the rotation of the purging device 2. A fixed connection is provided between the top ends of the connecting rods 3-3 and the rotating shaft 3-2. The rotation of the rotating shaft 3-2 drives the connecting rods 3-3 to rotate. The setting that the bottom ends of the connecting rods 3-3 are hinged to the top surface of the mounting plate 2-1 enables the mounting plate 2-1 to follow the position change of the connecting rods 3-3 when the connecting rods 3-3 rotate to adapt to the position of the steel beam 2-3-1.

[0047] Further, the conveying device 2-2 includes a linear module 2-2-1 and a sliding plate 2-2-2 fixedly arranged in the middle on the slider of the linear module 2-2-1. The linear module 2-2-1 is fixedly installed along the left-right direction in the middle of one side of the bottom surface of the mounting plate 2-1. On the bottom surface of the mounting plate 2-1 on both the front and rear sides of the linear module 2-2-1, "𠃊"-shaped conveying plates 2-2-3 are symmetrically arranged. At the inner end of the bottom surface of the "𠃊"-shaped conveying plate 2-2-3, a baffle 2-2-4 is provided. Between the "𠃊"-shaped conveying plate 2-2-3 and the baffle 2-2-4 is a conveying groove 2-2-5. The sliding plate 2-2-2 has an inverted "凵" - shaped structure. On the inner walls of the two side walls of the sliding plate 2-2-2, two groups of conveying wheels 2-2-6 are respectively rotatably arranged. The conveying wheels 2-2-6 arranged on both sides are respectively arranged in the conveying grooves 2-2-5 on the same side as them. When the linear module 2-2-1 works, the slider drives the sliding plate 2-2-2 to reciprocate. The conveying wheels 2-2-6 on both the front and rear sides of the sliding plate 2-2-2 slide in the conveying grooves 2-2-5. The setting of the conveying wheels 2-2-6 not only increases the smoothness of the sliding but also ensures the stability of the sliding plate 2-2-2 during sliding.

[0048] On the front and rear sides of the ducted fan 2-3-2, it is fixedly installed on the bottom surface of the sliding plate 2-2-2 through fixing rods 2-3-4. The linear module 2-2-1 drives the purging mechanism 2-3 to move by driving the sliding plate 2-2-2 to move. The top ends of the fixing rods 2-3-4 are fixedly connected to the bottom surface of the sliding plate 2-2-2, and the bottom ends of the fixing rods 2-3-4 are connected to the fixing blocks arranged on both sides of the duct 2-3-5 in the ducted fan 2-3-2.

[0049] Furthermore, the duct fan 2-3-2 includes a duct 2-3-5, a fan 2-3-6 disposed in the duct 2-3-5, and a fan drive motor 2-3-7, wherein the fan drive motor 2-3-7 is coaxially fixedly disposed at the rear side of the duct 2-3-5, the fan 2-3-6 is coaxially fixedly disposed at the output end of the fan drive motor 2-3-7, the fan drive motor 2-3-7 drives the fan 2-3-6 to rotate, a fairing 2-3-8 is fixedly disposed in the duct 2-3-5 in front of the fan 2-3-6, and the rear end of the duct 2-3-5 is coaxially fixedly connected to the air inlet of the purge air duct 2-3-1. The arrangement of the fairing 2-3-8 makes the wind entering the fan 2-3-6 uniform, which can ensure the stability of the purge air duct 2-3-1 during the purge process.

[0050] Furthermore, a filter chamber 2-3-9 is provided at the front end of the duct 2-3-5. The filter chamber 2-3-9 is a hollow cylindrical structure and is horizontally arranged.

Several groups of first filter holes 2-3-13 are provided on the cylindrical side wall 2-3-10 and the inner wall 2-3-11, and several groups of second filter holes 2-3-14 are provided on the outer wall 2-3-12. The diameter of the second filter holes 2-3-14 is smaller than the diameter of the first filter holes 2-3-13. The setting of the filter chamber 2-3-9 can clean and filter the wind before it enters, so as to avoid dust entering the purge air duct 2-3-1 for too long and affecting the purge efficiency. The dust falls into the filter chamber 2-3-9 after passing through the second filter hole 2-3-14. Since the diameter of the first filter hole 2-3-13 is very small, the dust can no longer follow it into the interior, that is, the dust is collected. After the purge is completed, the dust accumulated in the filter chamber 2-3-9 is manually processed.

[0051] Furthermore, the fan drive motor 2-3-7 is a brushless motor. The brushless motor has a long life and a high speed, which can increase the blowing force.

[0052] Further, the air outlet device 2-3-3 includes a conical air outlet pipe 2-3-15 and a flat air outlet end 2-3-16 provided at the small end of the conical air outlet pipe 2-3-15. The conical and flat settings can make the air outlet more concentrated and more convenient for cleaning the steel beam with a horizontal top surface. The air outlet device 2-3-3 includes a conical air outlet pipe 2-3-15 and a flat air outlet end 2-3-16 provided at the small end of the conical air outlet pipe 2-3-15; the conical air outlet pipe 2-3-15 is a conical corrugated pipe structure, and the setting of the corrugated pipe structure facilitates the conical air outlet pipe 2-3-15 to change direction. The air outlet device 2-3-3 is provided with an air outlet direction adjustment device 2-3-20, which is used to adjust the direction of the flat air outlet end 2-3-16 according to the actual blowing position of the factory, and can be horizontally outward, vertically downward, or tilted for blowing.

The gear driving motor 2-3-25 is electrically connected to the control system. When it is necessary to blow air downward, the control system controls the gear driving motor 2-3-25 to work, driving the driving gear 2-3-24 to rotate. Under the meshing transmission action between the gear driving motor 2-3-25 and the arc-shaped rack 2-3-23, the flat air outlet end 2-3-16 moves along the arc-shaped rack 2-3-23 until its opening is downward.
