Utility model content
The main purpose of the utility model is to provide one kind, when at least solving closing manhole, by illumination and will lead to
Wind devices are packed up, and when lower task, which will rearrange, causes workload to increase, and cannot effectively prevent people using when temporarily blocking
The entrance technical problem of member.
To achieve the goals above, the utility model provides a kind of restricted clearance safety device for operation, comprising: frame
Body, protective net and magnet, the notch section passed through for pipeline is formed on the downside of the framework, and the framework surrounds the protection
The circumferential of net is arranged and connect with the protective net, and the magnet is mounted in the framework.
Preferably, the framework is square or round.
Preferably, a length of 600mm of inner edge of the square framework, the internal diameter of the circular framework are 600mm.
Preferably, yellow paint is coated on the framework and protective net.
Preferably, the protective net is made of steel wire.
Preferably, the restricted clearance safety device for operation further includes the warning text being mounted on the protective net
Portion.
Preferably, the warning character portion is adopted made of plastic.
Preferably, reflective membrane is posted on the surface of the warning character portion.
Preferably, knob is provided in the framework.
A possibility that the utility model can effectively prevent personnel to be strayed into substantially reduces the security risk of personnel, avoids
Lighting apparatus and compressed air line will be dismounted when closing manhole every time, so that more than heavy workload and site layout project safety
Condition is poor when equipment, the big problem of risk.
Other than objects, features and advantages described above, there are also other purposes, feature and excellent for the utility model
Point.Below with reference to figure, the utility model is described in further detail.
Detailed description of the invention
The Figure of description for constituting a part of the utility model is used to provide a further understanding of the present invention, this
The illustrative embodiments and their description of utility model do not constitute the improper limit to the utility model for explaining the utility model
It is fixed.In the accompanying drawings:
Fig. 1 is the schematic diagram of the utility model first embodiment；
Fig. 2 is the schematic diagram of the utility model second embodiment.
Wherein, the above drawings include the following reference numerals:
1, framework；2, protective net；3, magnet；4, notch section；5, character portion is warned；6, it shakes hands.
Specific embodiment
It should be noted that in the absence of conflict, the feature in the embodiments of the present invention and embodiment can
To be combined with each other.The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
In order to make those skilled in the art better understand the scheme of the utility model, below in conjunction with the utility model reality
The attached drawing in example is applied, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only the embodiment of the utility model a part, instead of all the embodiments.Based on the reality in the utility model
Example is applied, every other embodiment obtained by those of ordinary skill in the art without making creative efforts is all answered
When the range for belonging to the utility model protection.
It is especially a kind of to be used for thermal power generation according to the restricted clearance safety device for operation of the utility model embodiment
Factory's restricted clearance operation safety protection net, comprising: the downside of framework 1, protective net 2 and magnet 3, the framework 1 is formed with for pipe
The notch section 4 that line passes through, the framework 1 are arranged and connect with the protective net 2, the magnetic around the circumferential direction of the protective net 2
Iron 3 is mounted in the framework 1.Preferably, yellow paint is coated on the framework 1 and protective net 2.Preferably, the protection
Net 2 is made of steel wire.
In one embodiment, the iron plate that 50mm can be used in the framework 1 in the utility model is welded, and shape is in four directions
Shape or circle, interior side length or interior diameter 600mm (consistent with manhole size as defined in national regulation), surface brush yellow paint, in
Between protective net use steel wire, there is a groove (i.e. notch section 4) in this restricted clearance operation safety protection net outline border lower left corner,
Pass through convenient for scene illumination and the cable routing and compressed air line of ventilation equipment, while can be convenient personnel's break-off phase
Between, do not have to every time pack up illumination with ventilation equipment when withdrawing scene.
Multiple columnar magnet 3 are provided within one week in framework 1, when in use directly by the utility model in corresponding equipment
Manhole door on, since size and people Buddhism size are just coincide, and magnet 3 is closely attracted with people's sky flange, will not fall road, from
