Description
Technical Field
The invention relates to the technical field of power failure maintenance auxiliary devices, in particular to a guide mechanism for an electroscope head.
Background
The current electricity testing mode after power failure is to use an electroscope to test that the conductor has no voltage, and then the electroscope leaves the conductor and then performs electricity testing operation. During the period from when the electroscope leaves the conductor to when the grounding operation is completed, there is a monitored vacuum time in which a sudden call may be made, and the grounding operator may perform the grounding operation without knowing that the power is available, resulting in a serious malfunction of the live grounding. At present, a hook-type electroscope is developed gradually, and the electroscope is mainly in continuous contact with an overhead conductor by means of gravity of the electroscope, and when a line is suddenly electrified, the continuous contact electroscope works. Although, in order to solve the problem of poor contact caused by that in areas with large wind force, the electroscope swings back and forth, and the metal electroscope end of the electroscope cannot be fixed on the electroscope point, the applicant sets a clamping mechanism on the inner side of the hook to clamp the overhead conductor. However, because no guide mechanism exists, the lead is easy to be clamped on the part and cannot enter the electroscope head, the operation is time-consuming and labor-consuming, and misoperation is easy to be formed.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a guide mechanism for an electroscope head, which has a guide function and prevents an overhead conductor from being unable to enter the electroscope head on a part.
In order to solve the technical problems, the invention adopts the following technical scheme:

According to the guide mechanism for the electroscope head, the overhead conductor slides into the accommodating cavity along the guide mechanism, so that the overhead conductor can be prevented from being clamped on a part; the small lead can be prevented from accidentally entering from the gap and not entering the accommodating cavity while the movement of the part is not influenced, and the operation is simple, convenient and quick; after the overhead conductor is led to the accommodating cavity, the electroscope is fixed on the overhead conductor by utilizing the gravity of the electroscope and the clamping force of the clamping assembly, so that the electroscope and the overhead conductor keep in a continuous contact state, when the line is electrified suddenly, the continuous contact electroscope works, an alarm sound is sent out, a light source is emitted, a worker performing grounding operation can immediately stop the grounding operation, malignant misoperation accidents are avoided under the unknowing condition, and the use safety of the electroscope is improved.
Further, the guide mechanism is of an arc-shaped sheet structure with a smooth surface.

The longest guiding path can be obtained by the arrangement, so that the overhead conductor can stably slide along the outline of the arc-shaped sheet structure, and the best guiding effect is obtained.
Further, one end of the arc-shaped sheet structure, which is far away from the clamping assembly, is wound to form a cylindrical structure, and the cylindrical structure is in contact with the lower end face of the hook-shaped structure. The arrangement of the cylindrical structure can prevent unnecessary injury caused by the puncture of the arc-shaped sheet by workers, and ensure the safety of operation; the clearance between the arc-shaped sheet structure and the hook-shaped structure is very small, so that the movement of parts is not affected, and small wires can be prevented from accidentally entering from the clearance.

This arrangement can avoid damage to the overhead line by the protrusion while obtaining the longest guide path.
Further, the width of the arc-shaped sheet structure is equal to the width of the clamping assembly. The arc piece structure and clamping assembly's junction both sides face all parallel and level sets up, can avoid the damage of sharp limit to operating personnel and air wire in the operation.
Further, the end part of the hook-shaped structure is provided with a connecting end connected with the electroscope, and the top part of the hook-shaped structure is provided with an electroscope part for short-term contact to perform three-phase electroscope operation of the circuit. The electroscope head is connected with the electroscope through the connecting end, three-phase electroscope of the line is carried out through the electroscope part, then the overhead conductor is led into the accommodating space through the guiding mechanism, and the whole electroscope is hung on a phase which needs to be grounded through clamping the overhead conductor by the clamping component.
Further, the clamping assembly comprises two groups of clamping pieces which are arranged in a pairwise manner, one end of each clamping piece surrounds to form a containing space, and the other end of each clamping piece penetrates through the hook-shaped structure and is movably connected with the hook-shaped structure. One end of the clamping component is movably connected with the hook-shaped structure, so that the size of the accommodating space is adjustable, and the clamping component is suitable for fixing overhead conductors of different types.
Compared with the prior art, the invention has the beneficial effects that:
(1) According to the invention, the overhead conductor slides into the accommodating cavity along the guide mechanism, so that the overhead conductor can be prevented from being clamped on a part; the small lead can be prevented from accidentally entering from the gap and not entering the accommodating cavity while the movement of the part is not influenced, and the operation is simple, convenient and quick;
