Abstract
The invention discloses a gas chamber observation mechanism which comprises a transparent part. A concave arc surface is at least arranged on a side of the transparent part, so that a concave lens can be formed by the cylindrical transparent part. A flange is arranged at the outer edge of a first end of the transparent part, and an annular groove is formed in the flange. External threads are arranged at a second end of the transparent part. The gas chamber observation mechanism is fastened on a wallboard of a gas chamber in a threaded manner and is sealed by a sealing strip. The gas chamber observation mechanism has the advantages that the concave lens is used as an observation window, so that the observation range can be expanded, and the gas chamber observation mechanism can be mounted easily and firmly in the threaded manner.
Description
Technical field
The present invention relates to the parts of gas insulation switch cabinet, be specifically related to the observation element for the air chamber of gas insulation switch cabinet.
Background technology
The core component of gas insulation switch cabinet is air chamber, is wherein full of insulating gas (being generally sulphur hexafluoride) and switch block is installed.Air chamber is made by metal material conventionally, and sealing is to prevent Leakage Gas.
The wallboard of air chamber is provided with observation window, in order to observe situation in air chamber.Existing observation window is used plate glass or plastics.In order to observe scope larger in air chamber, current method is the area that increases observation window.Other method is to adopt camera to observe in air chamber, yet the cost of this method is very high.
Prior art adopts welding procedure, has risk of breakage.
Summary of the invention
The object of this invention is to provide the larger observation window structure in a kind of visual field.
According to the present invention, a kind of air chamber observation element, comprises Transparent Parts, and at least one side of this Transparent Parts is cancave cambered surface, thereby this Transparent Parts forms concavees lens.
In another embodiment, in the outer rim of the first end of this Transparent Parts, be provided with flange, this flange is provided with annular groove.
In another embodiment, the second end in this Transparent Parts is provided with external screw thread.
In another embodiment, at this second end, be provided with installed surface, this installed surface is parallel to the axis of this Transparent Parts.In another embodiment, at this second end, be provided with two symmetrical installed surfaces.
In another embodiment, in the described second end outside of this Transparent Parts, nut is installed.
In another embodiment, in this annular groove, annular sealing strip is installed.
The present invention adopts concavees lens can expand range of observation as observation window, and the screw thread mounting means using is simple, firm.

Embodiment
Below in conjunction with the preferred embodiments of the present invention, present invention is described.Many concrete details in description below, have been enumerated.Yet, it will be appreciated by those skilled in the art that the present invention also can not adopt some or all in these details and realize.In some situations, known technology is not described to avoid unnecessary obscuring.
As Figure 1-3, a kind of air chamber observation element (being labeled as 10 in Fig. 4), for the air chamber of gas insulation switch cabinet.This air chamber observation element 10 comprises a Transparent Parts 100, and it is as observation window.At least one end face of this Transparent Parts 100 is cancave cambered surface, thereby this Transparent Parts 100 forms concavees lens.In the embodiment show in figure 1, only at the first end 110 of this Transparent Parts, form concave surfaces.Yet those skilled in the art can understand, can form cancave cambered surface at any one end face, or all form cancave cambered surface at two end faces.Can adopt existing any suitable technology to form described cancave cambered surface.
In the present embodiment, this Transparent Parts is configured to cylindrical.And, at this first end 110 of this Transparent Parts, form flanges 120, and this flange dorsad a side of this first end 110 be formed with annular groove 122, for holding annular sealing strip 200.
On the second end 130 of this Transparent Parts, be formed with external screw thread (not shown).In one example, at the second end 130, be provided with installed surface 132.In an example, be provided with two installed surfaces symmetrical, that be parallel to this Transparent Parts axis.
With reference to figure 4, during installation, now annular sealing strip 200 is arranged in described annular groove 122.Then, this Transparent Parts 10 is passed to reserved hole 310 air chamber wallboard 300 from the inside of air chamber, wherein this first end 110 is inner towards this air chamber, and this second end 130 is outside towards this air chamber.
Those skilled in the art can understand, and the diameter in this hole 310 should adapt with the diameter of this Transparent Parts, that is, should be greater than the major diameter of external thread of this Transparent Parts and be less than the external diameter of this flange.In an example, the shape in hole 310 and described installed surface adapt.
In this Transparent Parts 10, external screw thread should at least a portion expose this air chamber wallboard 300, and the length of the threaded portion exposing should enough install threaded fastener 400, nut for example, thus this Transparent Parts 10 can be fixedly connected with this air chamber wallboard 300.
Although in this manual, this Transparent Parts 10 is described as being substantially cylindrical, yet according to actual needs, this Transparent Parts can be other shapes.Equally, although sealing strip is O type sealing strip in specification,, can be also the sealing strip of other shapes as required.
According to actual needs, on the architecture basics that can describe at this specification, increase other parts, to meet the demand of different applied environments.
In addition, in the present invention, the material of each parts can be determined according to concrete applied environment.For example, Transparent Parts can adopt resin or glass to make.
In conjunction with embodiment, the present invention be have been described in detail above.Yet, it will be appreciated by those skilled in the art that and also have within the scope of the invention some modifications and equivalent way.Therefore, claim of the present invention should be interpreted as comprising all such modifications and equivalent way.
