Description

DETAILED DESCRIPTION
[0026] like Figure 1-Figure 7 As shown, the utility model provides a technical solution: a multi-stage exhaust cooling device, including a connecting frame 1, a fixed pipe 3 and a connecting pipe 4, the inner side of the fixed pipe 3 is fixedly connected with a bracket 5, the inner side of the bracket 5 is fixedly connected with a motor 6, the inner side of the fixed pipe 3 is fixedly connected with a bracket 2 7, the inner side of the bracket 2 7 is fixedly connected with a rotating shaft 1 8, and the inner side of the connecting pipe 4 is provided with a linkage part 2, and the linkage part 2 includes: a bracket three 21, a rotating shaft two 22, a groove 23, a transmission block 24, a clamping block 25, a clamping groove 26, a torsion spring 27, a connecting groove 28, a clamping rod 29, a sliding rod 210, a protective cover 211, a rotating plate 212, a transmission groove 213, and an exhaust fan two 214.
[0027] The bracket three 21 is fixedly connected to the inner side of the connecting pipe 4, and the inner side of the bracket three 21 passes through and is rotatably connected with the rotating shaft 22. A connecting pipe 4 is added. First, the right side of the rotating shaft 22 is aligned with the left side of the rotating shaft 1 8, and the connecting pipe 4 is aligned and fitted with the side of the fixed pipe 3, so that the bracket three 21 drives the rotating shaft 22 to move together. A groove 23 is provided on the right side of the rotating shaft 22, and a transmission block 24 is hinged on the inner side of the groove 23. A clamping block 25 is fixedly connected to the surface of the transmission block 24. The clamping groove 26 is provided on the surface of the transmission block 24. A torsion spring 27 is fixedly connected to the surface of the transmission block 24. The end of the torsion spring 27 away from the transmission block 24 is fixedly connected to the inner side of the groove 23. The transmission block 24 rotates a certain distance and compresses the torsion spring 27. When the clamping block 25 exceeds the rotating plate 212 and is inserted into the connecting groove 28, the compressed torsion spring 27 will bounce the transmission block 24 so that the clamping block 25 is embedded between the rotating plate 212 and the connecting groove 28. A connecting groove 28 is provided on the left side of the second rotating shaft 22. A clamping rod 29 is passed through the inner side of the connecting groove 28. The clamping rod 29 is slidably connected to the connecting groove 28. The sliding rod 210 drives the clamping rod 29 to slide along the connecting groove 28, so that the clamping rod 29 is inserted into the clamping groove 26 provided on the surface of the transmission block 24. Then, the connecting pipe 4 and the fixed pipe 3 are welded to complete the connection. A sliding rod 210 is passed through the surface of the clamping rod 29. The sliding rod 210 is fixedly connected to the clamping rod 29. The protective cover 211 is rotated. The protective cover 211 drives the rotating plate 212 to rotate together. The transmission groove 213 provided on the surface of the rotating plate 212 rotates together. The transmission groove 213 resists the sliding rod 210, forcing the sliding rod 210 to slide along the transmission groove 213. The left side of the rotating shaft 22 is rotatably connected with a protective cover 211, and the inner side of the protective cover 211 is fixedly connected with a rotating plate 212. The bracket 3 21 drives the rotating shaft 22 to move together, and the transmission block 24 hinged on the inner side of the groove 23 on the right side of the rotating shaft 22 will be inserted into the protective cover 211, and the transmission block 24 will drive the clamping block 25 to contact the edge of the rotating plate 212, causing the transmission block 24 to rotate a certain distance. The surface of the rotating plate 212 is provided with a transmission groove 213, and the shape of the transmission groove 213 is arc-shaped, and the slide bar 210 penetrates the transmission groove 213 and is slidably connected. The left sides of the rotating shaft 1 8 and the rotating shaft 22 are both provided with a connecting groove 28, and the rotating shaft 22 penetrates and is fixedly connected with the exhaust fan 214. The side of the rotating shaft 8 close to the motor 6 is fixedly connected to the output shaft of the motor 6. The rotating shaft 8 passes through and is fixedly connected with an exhaust fan 9. When the device is in use, the fixed pipe 3 and the connecting pipe 4 are connected to the equipment that requires exhaust cooling through the connecting frame 1, the motor 6 is started, and the rotating shaft 8 is driven to rotate through the output shaft of the motor 6.
[0028] Based on the above embodiment, when the device is used, the fixed pipe 3 and the connecting pipe 4 are connected to the equipment that needs exhaust cooling through the connecting frame 1, and the motor 6 is started. The output shaft of the motor 6 drives the rotating shaft 8 to rotate, and the rotating shaft 8 will drive the exhaust fan 9 to rotate when rotating, so that the heat generated by the equipment during operation can be discharged. If the exhaust efficiency of a single set of exhaust fans 9 is insufficient, a connecting pipe 4 can be added, and the right side of the rotating shaft 22 is first aligned with the left side of the rotating shaft 1 8, and the connecting pipe 4 is aligned and fitted with the side of the fixed pipe 3, so that the bracket 3 21 drives the rotating shaft 22 to move together, and the transmission block 24 hinged on the inner side of the groove 23 on the right side of the rotating shaft 22 will be inserted into the protective cover 211, and the transmission block 24 will drive the block 25 to resist the edge of the rotating plate 212, causing the transmission block 24 to rotate a certain distance and compress the torsion spring 27. When the block 25 exceeds the rotating plate 212 and After being inserted into the connecting groove 28, the compressed torsion spring 27 will bounce the transmission block 24 so that the card block 25 is embedded between the rotating plate 212 and the connecting groove 28. At this time, the protective cover 211 is rotated, and the protective cover 211 will drive the rotating plate 212 to rotate together, and the transmission groove 213 opened on the surface of the rotating plate 212 will rotate together, and the transmission groove 213 will resist the sliding rod 210, forcing the sliding rod 210 to slide along the transmission groove 213, and the sliding rod 210 will drive the card rod 29 to slide along the connecting groove 28, so that the card rod 29 is inserted into the card groove 26 opened on the surface of the transmission block 24, and then the connecting pipe 4 and the fixed pipe 3 are welded to complete the connection. When the rotating shaft 1 8 is driven to rotate by the output shaft of the motor 6, the rotating shaft 2 22 will be driven to rotate together at the same time, so that the exhaust fan 1 9 and the exhaust fan 2 214 rotate synchronously, thereby realizing multi-stage exhaust, and the connecting pipe 4 can be modularly connected to increase the multi-stage exhaust efficiency and increase the cooling effect.
[0029] At the same time, through the engagement of the connecting groove 28 with the clamping block 25 and the transmission block 24, the axis of the rotating shaft 22 is kept consistent with that of the rotating shaft 1 8, preventing the connecting pipe 4 from shifting when connected to the fixed pipe 3, so that the rotating shaft 22 and the rotating shaft 1 8 can be stably connected, ensuring that the exhaust fan 214 can stably achieve the exhaust cooling effect.
[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
