[0035] It should be noted that, unless otherwise specified, all components in this utility model are known components in the prior art. For example, the exhaust hood uses a commonly known exhaust hood.

[0036] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of the present invention.

[0037] like Figure 1-3 As shown, a mobile pollution source exhaust capture device is characterized by comprising a support frame 1, a mobile component, and at least one set of pollution source capture components.

[0038] The pollution source capture assembly includes an air pump 2 and an exhaust hood 3; the air inlet of the air pump 2 is connected to one end of a flexible pipe 4, the other end of the flexible pipe 4 is connected to one end of a rigid pipe 5, the other end of the rigid pipe 5 is connected to the upper end of a telescopic pipe 6, and the lower end of the telescopic pipe 6 extends downward into the interior of the support frame 1 and is connected to the exhaust hood 3.

[0039] The movable component includes transverse slide rails 7 on both sides of the top of the support frame 1, and at least one longitudinal slide rail 8 on the support frame 1. The two ends of the longitudinal slide rail 8 are slidably mounted on the two transverse slide rails 7. A first connecting plate is slidably mounted on the longitudinal slide rail 8, and a second connecting plate 9 is slidably mounted at the bottom of the longitudinal slide rail 8. The first connecting plate and the second connecting plate 9 slide synchronously.

[0040] The first connecting plate is fixedly connected to the rigid pipe 5; the bottom end of the second connecting plate 9 is rotatably connected to the top of the first telescopic rod 10 through the first rotating shaft 11, and the bottom of the first telescopic rod 10 is rotatably connected to one side of the fixed plate 13 through the second rotating shaft 12; a fixed hole is opened in the middle of the fixed plate 13, and the lower part of the telescopic pipe 6 is fixedly installed inside 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 axes of the first rotating shaft 11 and the second rotating shaft 12 are perpendicular to each other.

[0042] In actual use, the rigid pipe 5 is moved on the horizontal plane by the horizontal slide rail 7 and the vertical slide rail 8, and the movement of the rigid pipe 5 can drive the telescopic pipe 6 and the exhaust hood 3 to move horizontally.

[0043] Meanwhile, since the fixed plate 13 is fixedly connected to the lower part of the telescopic pipe 6, and the fixed plate 13 can rotate relative to the first telescopic rod 10, the rotation of the fixed plate 13 can also drive the lower part of the telescopic pipe 6 and the exhaust hood 3 to deflect together, thereby realizing the rapid positioning and flexible adjustment of the exhaust hood 3 in the working area.

[0044] When the location of pollution source 7 changes during operation, the operator can adjust it promptly according to the site conditions, ensuring that the exhaust hood 3 is accurately moved above the pollution source. Fine-tuning of the hood's height and deflection angle further enables effective capture of smoke and harmful gases. This device does not rely on sensors or positioning systems, has a simple overall structure, stable operation, and convenient maintenance. It is suitable for industrial sites where frequent changes in work locations or where pollution source locations are not fixed.

[0045] As a preferred option, such as Figure 5 As shown, the four corners of the bottom of the fixed plate 13 are rotatably connected to one end of a second telescopic rod 15 via a third rotating shaft 14, and the other end of the second telescopic rod 15 is connected to the four corners of the exhaust hood 3 respectively.

[0046] Preferably, the four corners of the exhaust hood 3 are connected to the other end of the corresponding second telescopic rod 15 by hooks 16.

[0047] The second telescopic rod 15 is rotated by the third rotating shaft 14, and the extension and retraction of the second telescopic rod 15 together realize the extension and retraction of the exhaust hood 3, allowing for fine adjustment of the opening size. This enables the exhaust hood 3 to be quickly positioned and flexibly adjusted within the working area.

[0048] The exhaust hood 3 is a flexible exhaust hood, as is customarily selected in the field.

[0049] As a preferred option, it includes two sets of pollution source capture components;

[0050] Two longitudinal slide rails 8 are provided on the support frame 1.

[0051] As a preferred embodiment, a first push motor is provided on the same side of both transverse slide rails 7, and the output shaft of the first push motor is connected to the two longitudinal slide rails 8 respectively;

[0052] A second push motor is provided on the longitudinal slide rail 8, and the output shaft of the second push motor is connected to the first connecting member;

[0053] The bottom of the second connecting plate 9 is equipped with a third push motor and a first rotation 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 drive motor is coaxially connected to the first telescopic rod 10;

[0056] A second rotating motor is provided at the lower part of the first telescopic rod 10, 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 that corresponds one-to-one with the third rotating shaft 14, and the output shaft of the third rotating motor is coaxially connected with its corresponding third rotating shaft 14.

[0058] Further preferred options include a controller;

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

[0060] Automatic control is achieved through the coordinated operation of the controller and motor using existing algorithms, without relying on sensors or positioning systems. The overall structure is simple, the operation is stable, and the maintenance is convenient. It is suitable for industrial sites where work points need to be changed frequently or where the location of pollution sources is not fixed.

[0061] The entire process can be repeated multiple times. The operator flexibly adjusts the position of the exhaust hood 3 according to the actual movement of the pollution source. The entire exhaust control process is completed by manual decision-making and controller execution, offering advantages such as convenient structure, direct response, and easy maintenance. Because this system has two robotic arms and an exhaust hood, it can capture at least two non-adjacent pollutants within the work area. This system is suitable for industrial operation scenarios where the location of pollution sources changes frequently but there is no need for complex automatic identification, effectively improving exhaust efficiency and reducing the operational intensity of manually moving the exhaust device.
