Description

Technical Field

[0001] The present invention relates to the technical field of an auxiliary device for replacing an electric meter, and more specifically, to a rapid insulation device and an outer layer protection mechanism thereof. Background Art

[0002] In order to ensure the reliability of power supply and ensure high-quality service to customers, electric meters need to be replaced regularly. At present, the method of live wiring is often used to replace electric meters. The old meter is first removed and then the new meter is installed. When working with live wires, it is necessary to untie the old interface, cut the wires, remove the wire insulation, and pull out the wires inserted in the meter. At this time, the conductors will be exposed and there will be a risk of electric shock. During live working, whether it is a live line or a line that may reverse power supply, the cut line needs to be insulated. The common practice is to wrap the exposed conductor with insulating tape. However, due to the large amount of work required to replace the meter, wrapping it with insulating tape not only has low work efficiency, but also causes waste of consumables such as insulating tape. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a rapid insulation device and an outer layer protection mechanism thereof to protect the safety of an operator when performing live operations.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] Provided is an outer layer protection mechanism of a rapid insulation device, comprising a first protection mechanism and a second protection mechanism hingedly arranged via a connecting shaft, wherein the first protection mechanism and the second protection mechanism are at least partially cross-overlapped to form a cavity for accommodating an inner layer clamping mechanism; the first protection mechanism and the second protection mechanism are both insulating structures.

[0006] The outer protective mechanism of the rapid insulation device of the present invention, the first protective mechanism and the second protective mechanism are hingedly arranged so that the first protective mechanism and the second protective mechanism can be opened and closed, which is convenient for live operation in the protective mechanism, comprehensively covers the exposed conductor, and ensures the personal safety of the operator.

[0007] Furthermore, the first protection mechanism comprises a first hand-held part, a first connecting part and a first fan part connected in sequence, and an acute angle is formed between the first fan part and the first connecting part. The first hand-held part is operated to drive the first fan part to rotate, so that the conductor can enter the inner layer clamping mechanism.

[0008] Furthermore, the first hand-held portion is provided with a first force-applying portion tilted toward a side away from the connecting shaft. The arrangement of the first force-applying portion tilting toward one side conforms to the lever principle and saves effort in operation.

[0009] Furthermore, the second protection mechanism includes a second handheld portion, a second connecting portion, and a second fan portion connected in sequence, the second handheld portion, the second connecting portion, and the second fan portion are symmetrically arranged with the first handheld portion, the first connecting portion, and the first fan portion about the first symmetry plane, respectively, and the first fan portion and the second fan portion are arranged concentrically. The second handheld portion is operated to drive the second fan portion to rotate, so that the conductor can enter the inner layer clamping mechanism; the first fan portion and the second fan portion are arranged concentrically, and the rotation of the two does not interfere with each other.

[0010] Furthermore, the diameter of the first fan is greater than the diameter of the second fan, and the inner arc length of the cross section of the first fan is not less than the outer arc length of the cross section of the second fan. The first fan cover is arranged on the outer side of the second fan, and double-layer insulation protection is provided to reduce the possibility of accidental electric shock.

[0011] Furthermore, the second hand-held part is provided with a second force-applying part tilted away from the connecting shaft, and the second force-applying part is symmetrically arranged with the first force-applying part about the second symmetric plane. The arrangement of the second force-applying part tilted to one side conforms to the lever principle, and the operation is labor-saving; the first and second protection mechanisms can be opened by squeezing the first and second force-applying parts inward; a spring can be sleeved on the connecting shaft so that the first and second force-applying parts move outward and close under the action of elastic force.

[0012] Furthermore, the first symmetry plane and the second symmetry plane overlap and both pass through the center line of the connecting shaft. The structure is compact, and the first protection structure and the second protection structure rotate stably, effectively avoiding mutual interference between the two.

[0013] Furthermore, a limit mechanism for limiting the relative position of the first protection mechanism and the second protection mechanism is provided at the hinge of the first protection mechanism and the second protection mechanism, so as to control the relative position of the rotation between the first protection mechanism and the second protection mechanism, and avoid the problem of loose structure caused by too large an opening and the problem of wires being unable to enter caused by too small an opening.

[0014] Furthermore, the limiting mechanism includes an arc groove provided on the first protection mechanism and a limiting column provided on the second protection mechanism, the center of the arc groove is provided on the center line of the connecting shaft, and the limiting column slides in the arc groove. The limiting column slides in the arc groove to play a role of positioning and limiting, thereby enhancing the stability of the relative movement between the first protection mechanism and the second protection mechanism and preventing the opening from being too large or too small.

[0015] The present invention also provides a rapid insulation device, comprising the outer layer protection mechanism as described above, and also comprising an inner layer clamping mechanism arranged inside the outer layer protection mechanism.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The outer layer protection mechanism of the rapid insulation device of the present invention sets the inner layer clamping mechanism on the inner side of the outer layer protection mechanism to fully cover the exposed conductor, thereby reducing the possibility of accidental electric shock and ensuring the personal safety of the operator;

[0018] (2) The quick insulation device of the present invention can achieve insulation by clamping the exposed conductor into the inner clamping mechanism, and the insulation can be completed by loosening the exposed conductor, thereby improving work efficiency, being reusable, and avoiding the waste of consumables such as insulating tape.
