Technical field
The utility model relates to high voltage electric equipment field, particularly relates to a kind of spring mechanism preventing easily rebounding during isolation knife on/off switch for wind energy combined electrical apparatus.
Background technology
Existing wind energy combined electrical apparatus, when isolation knife closes, isolate the holding piece strain on tool rest, isolation knife of now upspringing, and when electrical equipment vibrates, isolation knife also has the possibility of upspringing, and there is potential safety hazard.
Utility model content
The purpose of this utility model overcomes the defect that prior art exists, and provides a kind of and prevent isolation knife from upspringing and improve the centering spring mechanism for wind energy combined electrical apparatus of production safety coefficient.
The utility model solves the technical scheme that its technical problem adopts:
Centering spring mechanism for wind energy combined electrical apparatus of the present utility model, comprise the main shaft be installed in rotation on axle bed and the isolation tool rest be arranged on main shaft, one end fixed installation connecting lever of described main shaft, described connecting lever installs dwang, one end of described dwang is free hinged end, described free hinged end and described connecting lever hinged, described free hinged end is along with main axis, other one end of described dwang is the end that is fixedly hinged, the described end that is fixedly hinged is hinged with hinged seat, described dwang is expansion link, and described expansion link is socketed stage clip.
Dwang described in the utility model comprises the first expansion link and the second expansion link, one end of described first expansion link has cannulated sleeve, in addition one end and described hinged seat hinged, one end of described second expansion link is socketed in described cannulated sleeve and also can be free to slide in cannulated sleeve, and other one end and the described connecting lever of described second expansion link are hinged.
First expansion link described in the utility model is provided with the first fixed block, and described second expansion link is provided with the second fixed block, and described stage clip is stuck between the first fixed block and the second fixed block.
Connecting lever described in the utility model has draw-in groove, and described draw-in groove is fastened on described main shaft, and described draw-in groove is mounted by means of bolts on main shaft.
Isolation tool rest described in the utility model installs isolation knife.
The beneficial effect of the centering spring mechanism for wind energy combined electrical apparatus of the present utility model is: the centering spring mechanism for wind energy combined electrical apparatus of the present utility model comprises the main shaft be installed in rotation on axle bed and the isolation tool rest be arranged on main shaft, one end fixed installation connecting lever of main shaft, connecting lever installs dwang, one end of dwang is free hinged end, free hinged end and connecting lever hinged, free hinged end is along with main axis, other one end of dwang is the end that is fixedly hinged, the end that is fixedly hinged is hinged with hinged seat, dwang is expansion link, expansion link is socketed stage clip, stage clip can be extruded when dwang rotates, make stage clip strain, correspondingly stage clip can apply the pressure in direction to the free hinged end of dwang, and power is passed to main shaft by connecting lever by free hinged end, isolation knife on main shaft will be upspring and must be overcome the pressure of stage clip, and the power be subject to when generally isolation knife is upspring is less than the pressure of stage clip, therefore isolation knife cannot be upspring, thus ensure that the safety in utilization of wind energy combined electrical apparatus.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the centering spring whole mechanism structural representation for wind energy combined electrical apparatus of the present utility model;
Fig. 2 is stage clip scheme of installation of the present utility model.
Wherein: main shaft 1; Isolation tool rest 2; Connecting lever 3; Dwang 4, the first expansion link 41, second expansion link 42, first fixed block 43, second fixed block 44; Hinged seat 5; Stage clip 6.
Embodiment
Embodiment one:
As shown in Figure 1-2, the centering spring mechanism for wind energy combined electrical apparatus of the present embodiment comprises the main shaft 1 be installed in rotation on axle bed and the isolation tool rest 2 be arranged on main shaft 1, isolation tool rest 2 installs isolation knife, one end fixed installation connecting lever 3 of main shaft 1, connecting lever 3 has draw-in groove, draw-in groove is fastened on main shaft 1, and draw-in groove is mounted by means of bolts on main shaft 1.
As shown in Figure 1, connecting lever 3 is provided with dwang 4, particularly, one end of dwang 4 is free hinged end, free hinged end and connecting lever 3 hinged, free hinged end freely can rotate along with main shaft 1, other one end of dwang 4 is the end that is fixedly hinged, the end that is fixedly hinged is hinged with hinged seat 5, and hinged seat 5 is fixed installation, dwang 4 with hinged seat 5 for fulcrum can rotate around hinged seat 5.
As shown in Figure 1-2, in order to make stage clip 6 can free-extension, dwang 4 is designed to expansion link, expansion link is socketed stage clip 6, particularly, dwang 4 comprises the first expansion link 41 and the second expansion link 42, one end of first expansion link 41 has cannulated sleeve, in addition one end and hinged seat 5 hinged, one end of the second expansion link 42 to be socketed in cannulated sleeve and can be free to slide in cannulated sleeve, and other one end and the connecting lever 3 of the second expansion link 42 are hinged.In order to fix stage clip 6 better, the first expansion link 41 is provided with the first fixed block 43, second expansion link 42 and is provided with the second fixed block 44, and stage clip 6 is stuck between the first fixed block 43 and the second fixed block 44, prevents stage clip 6 play.
Connecting lever 3 can be driven to rotate when main shaft 1 rotates, connecting lever 3 is while rotation, dwang 4 can be driven to rotate, the free hinged end of dwang 4 can change with the distance of holding that is fixedly hinged, thus correspondingly expansion link stretches, there is deformation in stage clip 6, and the pressure of generation makes isolation switch all stressed when conjunction point position, prevent isolation knife from upspringing or unusual fluctuation, keep the fail safe of electrical equipment.
When stage clip 6 and connecting lever 3 on the same line time, isolation knife is stressed maximum, and now position is dead-centre position, and isolation knife is locked in relevant position by stage clip 6 firmly, and isolation knife must overcome stage clip 6 pressure and just can upspring.
Should be appreciated that specific embodiment described above only for explaining, and be not used in restriction.By spirit institute's apparent change of extending out or the protection range that is still in of variation among.
