Description

Technical Field

[0001] This utility model relates to the field of high-level windows, specifically to a high-level window switch device for substations. Background Technology

[0002] Some of the windows in a substation are high-level windows, which cannot be opened normally. To open them for ventilation, operators need to use a ladder to support the high-level windows and climb up to open and close them, which is very troublesome and affects the safety of the operators. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a substation high-level window switch device.

[0004] This utility model is achieved through the following technical solution:

[0005] A substation high-level window switch device includes a high-level window and an outward-opening window that can be rotated open. A downwardly extending pivot is installed on the outside of the outward-opening window. The pivot is hinged to a pull rod via a connecting rod. The pull rod is hinged to the front end of the outward-opening window. A driver is provided at the bottom of the pivot.

[0006] Further optionally, the drive includes a housing, within which a turbine connected to the bottom of a rotating shaft is disposed, one side of the turbine being engaged with a worm gear, the worm gear being rotatably supported and connected to the housing, and the outer end of the worm gear being connected and fixed to a handwheel.

[0007] Alternatively, the pivot is rotatably supported on the side of the high-mounted window by multiple rotating support blocks.

[0008] Alternatively, the connecting rod can be fixed perpendicularly to the pivot.

[0009] Alternatively, the actuator can be fixed to the wall below the high-mounted window.

[0010] Compared with existing technologies, the advantages of this utility model are: the utility model has a simple structure and is easy to operate, making it convenient to open and close the outward-opening windows of high-level windows without the need for climbing ladders, thus greatly improving safety. At the same time, the worm gear drive has a self-locking function to prevent the closed outward-opening windows from loosening and opening. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0015] like Figure 1 As shown, a substation high-level window switch device includes a high-level window 1 and an outward-opening window 2 that can be rotated and opened. A downward-extending rotating shaft 3 is installed on the outside of the outward-opening window 2. The rotating shaft 3 is a hollow shaft and is lightweight. The rotating shaft 3 is hinged and fixed to a pull rod 5 through a connecting rod 4. The pull rod 5 is hinged and fixed to the front end of the outward-opening window 2. A driver 6 is provided at the bottom of the rotating shaft 3.

[0016] like Figure 2 As shown, the drive 6 includes a housing 7, inside which is a turbine 8 connected to the bottom of the rotating shaft 3. One side of the turbine 8 is engaged with a worm gear 9. The worm gear 9 is rotatably supported and connected to the housing 7. The outer end of the worm gear 9 is connected and fixed to the handwheel 10. The turbine 8 and worm gear 9 drive have good self-locking properties to prevent loosening when the outward-opening window 2 is closed.

[0017] like Figure 1 As shown, the rotating shaft 3 is rotatably supported on the side of the high-position window 1 by multiple rotating support blocks.

[0018] like Figure 1 As shown, connecting rod 4 is fixed perpendicularly to rotating shaft 3.

[0019] like Figure 1 As shown, the driver 6 is fixed to the wall below the high-level window 1.

[0020] The implementation principle of a substation high-level window switch device according to an embodiment of this application is as follows:

[0021] When opening the outward-opening window 2 of the high-level window 1, the operator operates the drive 6 on the floor platform, rotates the handwheel 10 of the drive 6, and drives the worm gear 9 to rotate through the handwheel 10, thereby rotating the turbine 8. The turbine 8 drives the rotating shaft 3 to rotate outward, and the rotating shaft 3 pulls the outward-opening window 2 to rotate and open through the connecting rod 4 and the pull rod 5. This makes opening and closing more convenient, without the need to use a ladder to climb, and greatly improves safety.

[0022] When closed, the handwheel 10 is rotated in the opposite direction, thereby causing the shaft 3 to rotate in the opposite direction to close the outward opening window 2. Moreover, the turbine 8 and worm 9 of the drive 6 have a self-locking function. When the lead angle of the worm 9 with the self-locking function is less than the equivalent friction angle between the meshing gear teeth, the mechanism has self-locking properties and can achieve reverse self-locking. That is, the worm 9 can only drive the turbine 8, and the turbine 8 cannot drive the worm 9. Therefore, when the outward opening window 2 is closed, it will not rotate and loosen to open.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
