DETAILED DESCRIPTION

[0035] It should be noted that all components in the present application, such as without special instructions, all adopt the components known in the prior art. For example, the exhaust hood adopts the commonly known exhaust hood.

[0036] The specific embodiments of the present application are given below. It should be noted that the present application is not limited to the following specific embodiments, and any equivalent transformation made on the basis of the technical solutions of the present application falls within the protection scope of the present application.

[0037] As shown in Figures 1-3 , a mobile pollution source exhaust capturing device, characterized in that it comprises a support frame 1, a moving assembly and at least one set of pollution source capturing assembly;

[0038] The pollution source trapping assembly comprises an air pump 2 and an exhaust hood 3; one end of the air pump 2 is connected with a flexible pipe 4, the other end of the flexible pipe 4 is connected with one end of a rigid pipe 5, the other end of the rigid pipe 5 is connected with the upper end of an extendable pipe 6, the lower end of the extendable pipe 6 extends into the inside of the support frame 1 and is connected with the exhaust hood 3;

[0039] The moving assembly comprises two lateral sliding rails 7 arranged on the top of the support frame 1, at least one longitudinal sliding rail 8 arranged on the support frame 1, the two ends of the longitudinal sliding rail 8 being slidingly arranged on the two lateral sliding rails 7, a first connecting plate being slidingly arranged on the longitudinal sliding rail 8, a second connecting plate 9 being slidingly arranged on the bottom of the longitudinal sliding rail 8, and the first connecting plate and the second connecting plate 9 being synchronously sliding.

[0040] The first connecting plate is fixedly connected with the rigid pipe 5, the bottom end of the second connecting plate 9 is rotatably connected with the top of a first extendable rod 10 through a first rotating shaft 11, the bottom of the first extendable rod 10 is rotatably connected with one side of a fixed plate 13 through a second rotating shaft 12, the fixed plate 13 is provided with a fixed hole in the middle, and the lower part of the extendable pipe 6 is fixedly arranged in the fixed hole.

[0041] The central axis of the first rotating shaft 11 and the central axis of the second rotating shaft 12 are both parallel to the horizontal plane, and the central axis of the first rotating shaft 11 and the central axis of the second rotating shaft 12 are perpendicular to each other.

[0042] In actual use, the rigid pipe 5 moves on the horizontal plane through the lateral sliding rails 7 and the longitudinal sliding rail 8, and the movement of the rigid pipe 5 drives the horizontal movement of the extendable pipe 6 and the exhaust hood 3.

[0043] Meanwhile, since the fixed plate 13 is fixedly connected with the lower part of the extendable pipe 6 and the fixed plate 13 can rotate relative to the first extendable rod 10, the rotation of the fixed plate 13 drives the lower part of the extendable pipe 6 and the exhaust hood 3 to deflect together, so as to realize the rapid positioning and flexible adjustment of the exhaust hood 3 in the working area.

[0044] When the pollution source 7 changes position during the operation, the operator can adjust in time according to the on-site situation, so as to accurately move the exhaust hood 3 above the pollution source, and then finely adjust the height and deflection angle of the exhaust hood, so as to effectively trap the smoke and harmful gas. The device does not need to rely on sensors or positioning systems, has a simple overall structure, stable operation, convenient maintenance, and is suitable for industrial sites where the working point needs to be frequently changed or the position of the pollution source is not fixed.

[0045] As a preferred solution, as shown in Figure 5 the bottom of the fixed plate 13 is rotatably connected with one end of a second extendable rod 15 through a third rotating shaft 14 at the four corners, and the other end of the second extendable rod 15 is respectively connected to the four corners of the exhaust hood 3.

[0046] Further preferably, the four corners of the exhaust hood 3 are connected to the other ends of the corresponding second telescopic rods 15 through hooks 16.

[0047] The rotation of the second telescopic rods 15 driven by the third rotating shaft 14 and the telescoping of the second telescopic rods 15 together realize the telescoping and expansion of the exhaust hood 3, and the fine adjustment of the opening size. Thus, the exhaust hood 3 can be quickly positioned and flexibly adjusted in the working area.

[0048] Preferably, the exhaust hood 3 is flexible.

[0049] As a preferred solution, two groups of pollution source capturing assemblies are included.

[0050] The support frame 1 is provided with two longitudinal sliding rails 8.

[0051] As a preferred solution, the same side of the two transverse sliding rails 7 is provided with a first pushing motor, and the output shafts of the first pushing motors are connected to the two longitudinal sliding rails 8, respectively.

[0052] The longitudinal sliding rails 8 are provided with a second pushing motor, and the output shaft of the second pushing motor is connected to the first connecting piece.

[0053] The second connecting plate 9 is provided at the bottom with a third pushing motor and a first rotating motor.

[0054] The output shaft of the first rotating motor is coaxially connected to the first rotating shaft 11.

[0055] The output shaft of the third pushing motor is coaxially connected to the first telescopic rod 10.

[0056] The lower part of the first telescopic rod 10 is provided with a second rotating motor, and the output shaft of the second rotating motor is coaxially connected to the second rotating shaft.

[0057] The bottom of the fixed plate 13 is provided with a third rotating motor corresponding to the third rotating shaft 14, and the output shaft of the third rotating motor is coaxially connected to the corresponding third rotating shaft 14.

[0058] Further preferably, a controller is further included.

[0059] The controller is connected to the air pump 2, the first pushing motor, the second pushing motor, the third pushing motor, the first rotating motor, the second rotating motor, and the third rotating motor, respectively.

[0060] Through the cooperative work of the controller and the motors, the existing algorithm is used to realize automatic control without relying on sensors or positioning systems. The overall structure is simple, stable in operation, easy to maintain, and suitable for industrial sites where the working point needs to be frequently changed or the position of the pollution source is not fixed.

[0061] The whole process can be repeated multiple times, and the operator can flexibly control the position adjustment of the exhaust hood 3 according to the actual movement of the pollution source. The whole exhaust control process is completed by manual decision and controller execution, and has the advantages of convenient structure, direct response, convenient maintenance and the like. Since the system has two mechanical arms and an exhaust hood, at least two non-adjacent pollutants in the work area can be captured. The system is suitable for industrial work scenes where the position of the pollution source changes frequently but there is no complex automatic identification requirement, effectively improves the exhaust efficiency and reduces the operation strength of manually moving the exhaust device.
