The gas collection hood has a gas collection port and an exhaust hole. The exhaust hole is connected to one end of the telescopic pipe, which is extendable, retractable, and bendable. The other end of the telescopic pipe is connected to one end of the exhaust pipe. The gas collection hood is mounted on the track and can move along the track. As the gas collection hood moves along the track, the telescopic pipe extends, retracts, or bends accordingly. This invention has advantages such as simple structure, high gas collection efficiency, and good performance.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 This utility model provides a technical solution: A movable gas collection hood includes a moving mechanism 1, and a gas collection mechanism 2 is provided inside the moving mechanism 1 for adjusting the gas collection angle. The gas collection mechanism 2 includes: The adjustment unit 21 is located inside the moving mechanism 1 and includes a fixed frame 211. A gas collecting hood 212 is rotatably mounted inside the fixed frame 211. A folded hose 213 is fixedly mounted on the top of the gas collecting hood 212. The gas collecting angle can be adjusted by rotating the gas collecting hood 212 inside the fixed frame 211. The rotating unit 22 is located inside the fixed frame 211 and is used to rotate the gas collection hood 212.

[0018] In this embodiment, the front shaft of the gas collection hood 212 extends through the fixing frame 211, and a worm gear 214 is fixedly installed on the surface of the front shaft of the gas collection hood 212. A mounting base 215 is fixedly installed on the left side of the front of the fixing frame 211, and a servo motor 218 is fixedly installed on the left side of the mounting base 215. The output end of the servo motor 218 extends through the mounting base 215 and a worm 217 is fixedly installed thereon. The worm 217 and the worm gear 214 are meshed together, and the rotation of the gas collection hood 212 is achieved through the worm 217 and the worm gear 214.

[0019] The servo motor 218, model EDSMT-2T110-020A, passes through the front shaft of the gas collection hood 212, through the fixing frame 211, and is equipped with a worm gear 214. At the same time, the servo motor 218 drives the worm 217 on the mounting base 215. Through the meshing transmission between the worm 217 and the worm gear 214, the motor drive adjustment of the rotation angle of the gas collection hood 212 is realized, so that the opening of the gas collection hood 212 can be quickly aligned with the pollution source on the side or not directly below, thereby effectively improving the efficiency and adaptability of exhaust gas collection.

[0020] In this embodiment, a bearing seat 216 is fixedly installed on the right side of the mounting base 215, and the end of the worm gear 217 away from the servo motor 218 is rotatably installed inside the bearing seat 216, through which the bearing seat 216 is used to support the worm gear 217.

[0021] It provides critical and stable radial support for the worm 217, effectively eliminating problems such as deformation, vibration or poor meshing that may occur in the worm 217 during transmission due to the cantilever structure.

[0022] In this embodiment, the rotating unit 22 includes a rotating seat 221, a rotating ring 222 is rotatably mounted inside the rotating seat 221, and a fixing bracket 211 is fixedly mounted on the bottom of the rotating ring 222. The rotating seat 221 has a first insertion hole 223 and a second insertion hole 224 inside, and the first insertion hole 223 and the second insertion hole 224 are opened at a right angle. The rotating ring 222 has a through hole 226 inside.

[0023] By setting up a rotating base 221 and a rotating ring 222 rotatably mounted inside it, and fixing the fixing frame 211 to the bottom of the rotating ring 222, and simultaneously opening a first insertion hole 223 and a second insertion hole 224 at right angles on the rotating base 221, and opening a through hole 226 on the rotating ring 222, a mechanical structure capable of intermittent 90-degree rotation is formed. This enables the entire gas collection mechanism 2 to drive the gas collection hood 212 to rotate and position in the horizontal plane, expanding the spatial coverage of the gas collection hood 212 and meeting the gas collection needs of pollution sources in different directions.

[0024] In this embodiment, a positioning post 225 is slidably inserted into the through hole 226, and the bottom end of the positioning post 225 is slidably inserted into the second insertion hole 224 to fix the position between the rotating ring 222 and the rotating seat 221.

[0025] By employing a positioning pin 225 that can slide inside the through hole 226 and be inserted into the second insertion hole 224 or the first insertion hole 223, a reliable mechanical and manually operable locking mechanism is provided. This structure utilizes the principle of a pin, and when the positioning pin 225 is inserted into the corresponding insertion hole, it can effectively prevent the relative rotation between the rotating ring 222 and the rotating seat 221, thereby firmly locking the gas collection hood 212 in the working position of 0 degrees or 90 degrees. Its structure is simple, the operation is intuitive, and the locking is firm, avoiding the problem of reduced gas collection efficiency caused by accidental rotation during operation.

[0026] In this embodiment, the moving mechanism 1 includes a base frame 11. Limiting lifting plates 12 are slidably installed on both sides of the interior of the base frame 11. Lead screws 13 are rotatably installed on both sides of the interior of the base frame 11, and the limiting lifting plates 12 are threadedly rotatably installed on the surface of the lead screws 13. Drive motors 14 are fixedly installed on both sides of the top of the base frame 11, and the top end of the lead screws 13 passes through the base frame 11 and is fixedly connected to the output end of the drive motors 14. A set of sliding rails 15 is fixedly installed on the top of the limiting lifting plates 12, and a sliding seat 16 is slidably installed above the sliding rails 15 via pulleys. A rotating seat 221 is fixedly installed inside the sliding seat 16.

[0027] The drive motor 14 is model KV3SF-8521F-WR, which is electrically connected to an external power supply and can be started and stopped by a human-operated control panel.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, firstly, the two drive motors 14 drive the two lead screws 13 to rotate synchronously. The lead screws 13 drive the two limit lifting plates 12 to move up and down synchronously. The limit lifting plates 12 drive the gas collecting mechanism 2 to move up and down synchronously through the sliding rail 15 and the sliding seat 16, adjusting the height of the gas collecting mechanism 2. The sliding seat 16 slides on the sliding rail 15 to adjust the lateral position of the gas collecting mechanism 2. Then, the servo motor 218 drives the worm gear 217 to rotate, the worm gear 217 drives the worm wheel 214 to rotate, and the worm wheel 214 drives the gas collecting hood 212 to rotate, so that the gas collecting direction of the gas collecting hood 212 changes to the side. The positioning pin 225 is pulled out, and the rotating ring 222 is rotated to drive the rotating seat 221 to rotate. When it rotates from above the through hole 226 to above the first insertion hole 223, the rotation angle of the rotating ring 222 is ninety degrees, so that the positioning pin 225 is inserted into the interior of the first insertion hole 223 through the through hole 226, and the position of the rotating ring 222 is fixed.
