Description

Technical Field

[0001] The utility model relates to the technical field of cross-flow fans, in particular to a cross-flow fan for locomotives. Background Art

[0002] Crossflow fan is also called crossflow fan. Its impeller is multi-leaf, long cylindrical, with forward multi-wing blades. Its structure is as follows Figure 1 As shown. When the impeller rotates, the airflow enters the blade grid from the impeller opening, passes through the inside of the impeller, and is discharged into the volute from the other side of the blade grid, forming a working airflow. The flow of air in the impeller is very complex, and the airflow velocity field is unstable. There is also a vortex in the impeller, with its center located near the volute tongue. The existence of the vortex causes a circulating flow to be generated at the output end of the impeller. Outside the vortex, the airflow streamlines in the impeller are arc-shaped, so that it can be used to cool and dissipate heat for some equipment. When dissipating heat for heating equipment on some locomotives or passenger cars, when installing the cross-flow fan on the heating equipment, most of the time, holes are drilled on the surface of the heating equipment, and then the cross-flow fan is fixed to the heating equipment with bolts. However, holes cannot be drilled on some heating equipment, which makes it impossible to install the cross-flow fan on the heating equipment, resulting in the heating equipment being unable to dissipate heat externally well, and the heating equipment is prone to damage.

[0003] Based on this, a cross-flow fan for locomotive is now provided, which can eliminate the disadvantages of existing devices. Utility Model Content

One end of the impeller 2 is fixedly connected to the connecting rod 401, and two groups of slots 402 are opened on the surface of the connecting rod 401. One end of the crossflow fan body 1 is provided with a connecting shell 403, and a plurality of groups of screw holes 404 are opened on the surface of the connecting shell 403. The inner wall of the screw hole 404 is threadedly connected with a screw 405, and one end of the screw 405 cooperates with the crossflow fan body 1. The interior of the connecting shell 403 is fixedly connected to the bearing 406, and the interior of the bearing 406 is fixedly connected to the two groups of blocks 407. The inner wall of the slot 402 is slidably connected to the block 40 7. One end of the connecting rod 401 is threadedly connected to the rotating block 408, and the top of the connecting shell 403 is fixedly connected to the second fixing plate 6. Insert the clamping block 407 into the clamping slot 402 to connect the bearing 406 to the connecting rod 401 through the clamping block 407. Twist the screw 405, and the screw 405 passes through the screw hole 404 and is threadedly connected to the cross flow fan body 1 to fix the connecting shell 403 on the cross flow fan body 1. Then twist the rotating block 408 to thread the rotating block 408 to the connecting rod 401. The rotating block 408 is fixed on the connecting rod 401 so that the connecting rod 401 can be clamped on the bearing 406. Start the drive motor 3 to make the impeller 2 rotate stably through the bearing 406 on the connecting rod 401.

[0028] In one embodiment, Figure 3 As shown, a plurality of groups of protrusions are provided on the surface of the rotating block 408 to increase the friction between the rotating block 408 and the hand, making it easier to twist the rotating block 408.

[0029] In one embodiment, Figure 4-Figure 6As shown, the mounting mechanism 7 includes a fixing frame 701, a limiting groove 702, a threaded hole 703, a first connecting plate 704, a second connecting plate 705, a threaded rod 706, a turntable 707, a rotating shaft 708, a clamp 709 and a limiting block 710.

The bottom of the clamp 709 is fixedly connected to a limiting block 710, and the inner wall of the limiting groove 702 cooperates with the limiting block 710. When the clamp 709 moves, the limiting block 710 fixed at the bottom of the clamp 709 plays a limiting role when sliding in the limiting groove 702, so that the clamp 709 will not rotate and will not shake when sliding.

[0034] Example 2

[0035] In one embodiment, Figure 6 As shown, when the mounting mechanism 7 is not needed, the crossflow fan body 7 is directly placed on the heating device of the locomotive through the first fixing plate 5 and the second fixing plate 6, and the bolt 9 is tightened. The bolt 9 passes through the fixing hole 8 and is threadedly connected to the heating device, so that the crossflow fan can be directly mounted on the heating device through the first fixing plate 5 and the second fixing plate 6.

[0036] Working principle: The above embodiment discloses a cross-flow fan for locomotives, wherein, when in use, the clamping block 407 is inserted into the clamping slot 402, so that the bearing 406 is connected to the connecting rod 401 through the clamping block 407, the screw 405 is screwed, the screw 405 passes through the screw hole 404 and is threadedly connected to the cross-flow fan body 1, so that the connecting shell 403 is fixed to the cross-flow fan body 1, and then the rotating block 408 is screwed to be threadedly connected to the connecting rod 401. The rotating block 408 is fixed to the connecting rod 401 so that the connecting rod 401 can be clamped on the bearing 406, and the driving motor 3 is started so that the impeller 2 can rotate stably through the bearing 406 on the connecting rod 401, and the fixing frame 701 is placed on the first fixing plate 5 and the second fixing plate 6, and the bolts 9 and 9 are screwed. The threaded hole 703 and the fixing hole 8 are threadedly connected with the nut 10, so that the mounting mechanism 7 can be fixed on the first fixing plate 5 and the second fixing plate 6. When the cross-flow fan body 1 needs to be installed on the heating equipment of the locomotive, the fixing frame 701 is placed on the connecting frame of the heating equipment, and the turntable 707 is rotated so that the threaded rod 706 can drive the clamp 709 to move forward through the rotating shaft 708. When the clamp 709 moves, the limit block 710 fixed at the bottom of the clamp 709 plays a limiting role when sliding in the limit groove 702, so that the clamp 709 will not rotate and will not shake when sliding. A clamp is formed between the clamp 709 and the first connecting plate 704, so that the cross-flow fan body 1 is fixed to the connecting frame of the locomotive heating equipment through the mounting mechanism 7, thereby completing the installation of the cross-flow fan.
