Abstract
The invention discloses a sealing mechanism and an operation tool for a grounding switch mechanical lock relieving device. Te sealing mechanism comprises a sealing frame, wherein a sealing cover pressed and fixed by a spring is arranged on the sealing frame; a through hole is formed in the sealing frame; a fixing hole is formed in the sealing frame; and the sealing frame is fixed on a switch mechanism box through a bolt passing through the fixing hole. The operation tool is a cylinder body of which one end is provided with a flange; an elliptical hole is formed in the end face of one end, which is provided with the flange, of the operation tool; and a fork is arranged at the other end of the operation tool. The operation tool is made of stainless steel. By the sealing mechanism, a mechanical lock in the mechanism box can be relieved by the operation tool outside the mechanism box; therefore, a control device of the grounding switch is operated, the mechanism box is not required to be opened again; and the safety of an operator is guaranteed, and safety production is facilitated.
Description
Technical field
The present invention relates to the annex of a kind of transformer station switch mechanism case, relate in particular to a kind of sealing mechanism and operation tool of grounding switch mechanical lock decontrol.
Background technology
The control device and the mechanical lock that comprise in the market grounding switch, grounding switch in transformer station's switch mechanism case commonly used, normally, operation is after switch operation is finished, to lock mechanism case safely.But, owing to also be provided with at present the control device of grounding switch in transformer station's switch mechanism case commonly used, after switch operation is finished, when again carrying out the control device of operational grounding disconnecting link, also need again to open this transformer station's switch mechanism case, again open the switch mechanism case and can bring very large potential safety hazard, threaten operating personnel's life security, be unfavorable for safety in production.
Summary of the invention
The present invention is directed to prior art and a kind of sealing mechanism and operation tool of simple to operation, safe grounding switch mechanical lock decontrol are provided.
The present invention realizes by following technical measures: the sealing mechanism of grounding switch mechanical lock decontrol, comprise sealing frame, be provided with on the sealing frame by spring compression, fixing seal cover, at the sealing frame through hole is set, the diameter of close seal cover one end of this through hole is greater than the diameter of this through hole away from seal cover one end; Also be provided with fixing hole on the described sealing frame, totally four of described fixing holes, be distributed in through hole around, the sealing frame is by passing being bolted on the switch mechanism case of fixing hole.
The operation tool of described grounding switch mechanical lock decontrol is that an end is with the cylinder of flange, have slotted eye on the end face of this operation tool with flange one end, the external diameter of the flange of this operation tool and through hole are near the equal diameters of seal cover one end, the external diameter of these operation tool flange both sides and through hole are away from the equal diameters of seal cover one end, and the degree of depth of described slotted eye is greater than the degree of depth of through hole on the sealing frame.The further improvement of this operation tool is that described operation tool is made by stainless steel, and this operation tool is provided with jag away from an end of flange.
Beneficial effect of the present invention is: this invention comprises sealing mechanism and operation tool, use operation tool to stretch into the through hole of sealing mechanism during work, outside at mechanism case just can be removed the mechanical lock mechanism in the mechanism case, after switch operation is finished, when again carrying out the control device of operational grounding disconnecting link, do not need again to open the switch mechanism case, guaranteed operating personnel's safety, be conducive to safety in production.

Fig. 2 is the cutaway view of sealing mechanism of the present invention;
Fig. 3 is the cutaway view figure of operation tool of the present invention;
Fig. 4 is the right view of Fig. 3.
Among the figure: 1 is sealing frame; 2 is spring; 3 is fixing hole; 4 is seal cover; 5 is operation tool; 6 is flange; 7 is slotted eye; 8 is through hole; 9 is jag.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
The sealing mechanism of a kind of grounding switch mechanical lock decontrol as shown in Figure 1 and Figure 2, sealing mechanism comprises sealing frame 1, be provided with the seal cover 4 that compresses, fixes by spring 2 on the sealing frame 1, should on sealing frame 1, also be provided with through hole 8, the diameter of these through hole 8 close seal cover 4 one ends is greater than the diameter of this through hole away from seal cover 4 one ends, namely these through hole 8 diameters do not wait, and are large near an end diameter of seal cover 4, are called larger diameter end; End diameter away from seal cover 4 is little, is called smaller diameter end; In the unlocking operation process, need operation tool and through hole 8 to be used; Also be provided with fixing hole 3 on the described sealing frame 1, totally four of described fixing holes 3, be distributed in through hole 8 around, sealing frame 1 is by passing being bolted on the switch mechanism case of fixing hole 3.
As shown in Figure 3, Figure 4, the operation tool 5 of described grounding switch mechanical lock decontrol is that an end is with the cylinder of flange 6, have slotted eye 7 on the end face of this operation tool with flange 6 one ends, the external diameter of the flange 6 of this operation tool and through hole 8 be near the equal diameters of seal cover one ends (being the equal diameters of the larger diameter end of the external diameter of flange 6 and through hole 8), and the external diameter of these operation tool flange both sides and through hole 8 are away from the equal diameters of seal cover one end the equal diameters of through hole 8 smaller diameter end (namely with).The degree of depth of described slotted eye is greater than the degree of depth of through hole on the sealing frame.In use, seal cover 4 is raised, exposed the through hole 8 on the sealing frame 1, operation tool 5 is extended through in the through hole 8 of sealing mechanism, at this moment, the flange 6 of operation tool 5 just in time closely cooperates with through hole 8 larger diameter end, and positions by the larger diameter end of through hole 8; Use operation tool to open operated to the mechanical lock in the switch mechanism case.Guarantee operating personnel's safety, be conducive to safety in production.
The further improvement of this operation tool is, described operation tool 5 is made by stainless steel, and this operation tool 5 is provided with jag 9 away from an end of flange 6.Jag 9 is set, so that convenient when operation tool 5 operated.
This invention comprise sealing mechanism and with the suitable operation tool of sealing mechanism, operation tool is by the through hole of sealing mechanism during work, outside at mechanism case just can be removed the mechanical lock mechanism in the mechanism case, thereby opening mechanism case again when the control device of grounding switch is operated, guarantee operating personnel's safety, be conducive to safety in production.
The present invention can pass through existing techniques in realizing without the technical characterictic of describing, and does not repeat them here.Certainly; above-mentioned explanation is not to be limitation of the present invention; the present invention also is not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
