Safety locking can be opened by the second solution lock section 3 using unlock magnetic card in underground, such staff can flee from underground,
It is unlocked by way of unlocking magnetic card, unlocking process enhanced convenience, and is not easy stolen personnel and opens peace easily
Full latch fitting improves the safety of manhole lid device.
When staff is stranded underground, underground might have many pernicious gases, and staff once sucks excessive
Pernicious gas after, it may appear that situations such as stupor, seriously affect the safety of trapped person, further, the manhole cover body 2
It is upper that there is ventilation opening.When staff is trapped in underground, quilt can be improved by ventilation mouth breathing to extraneous fresh air
The safety of oppressive member.
Further, there is display screen 21, display screen 21 is connected to link block, shows on the upper surface of manhole cover body
Display screen curtain is used for through the control signal outside link block acquisition, to replace the broadcasting content of display screen.In the present embodiment,
Display screen for showing the contents such as image or video, show screen broadcasting content control mode can there are many, optionally,
It shows that screen can connect network by link block, when needing to control the broadcasting content of display screen, network can be passed through
Control signal is issued to control the broadcast information of replacement display screen, such as: mobile phone can be used in staff or computer passes through
Network shows the broadcasting content of screen to control；Optionally, display screen can also be connected to preset end by link block
End equipment, and preset terminal device can be set in control room, such staff can pass through preset terminal device
To control the display content of replacement display screen.By display screen can with promotional contents such as playing pictures, images, such as: it is logical
The display screen crossed in manhole cover body can play the weather condition on the same day, can also play location information, road letter herein
Breath, retail shop's information etc., can also play the cultural and historical etc. about street herein, can also play city promotional videos or
Advertising image video of brand etc., in short, the display screen in manhole cover body can be used for carrying out the publicity of video or picture, and
The city street Zhong Meitiao can all have many well lid equipment, when citizen on the way walk, can encounter well lid everywhere, thus make
The range of publicity of display screen in manhole cover body is wider, can play preferable the effect of publicity, and traditional publicity mode one
As be all utilized in roadside and set up the modes such as billboard or advertisement screen to show the content of publicity, with traditional publicity mode
It compares, the publicity mode that the invention provides can play better the effect of publicity, wherein pass through the display in manhole cover body
Screen is that publicity mode never before seen, people can feel to be more willing to attempt to understand than comparatively fresh before publicize
This new-type publicity measures, can thus play preferable the effect of publicity, in addition, the viewing angle of traditional publicity mode
It is poor, at most the people of 180 degree around can be allow to watch, and when the poor position of angle is watched, it can also serious shadow
Viewing effect is rung, and in the technical solution that the invention provides, 360 degree of people are it can be seen that well lid around manhole cover body
Promotional content on ontology, the range for publicizing viewing is wider, and watches the viewing that can clearly complete from each angle
To the full content in display screen, and then preferable the effect of publicity can be played；In addition, traditional publicity mode is arranged to
This is higher, and there are also many places to be all not permitted this advertising of setting, can seriously affect the sight of people around, such as:
The sight of surrounding resident man may be stopped by billboard, and then will affect the life of surrounding resident, and in present specification
Display screen be then arranged in manhole cover body, and ground flush with each other is thus not in the problem of blocking sight, and
The setting position of manhole cover body will not be restricted, due to can all have well lid on every road, so the well lid of publicity can
It is publicized in arbitrary street locations with setting, and cost is also lower, maintenance is got up also easily；Finally, traditional
Billboard is very troublesome when replacing promotional content, and staff is needed to replace one by one, and replacing construction is longer, and
Replacement cost is larger, and the innovation and creation that present specification provides, and more convenient can carry out in replacement publicity, facilitate unified manage
Reason, when needing replacing promotional content, staff only needs remotely realize to well lid by preset terminal device
The promotional content of upper display screen is replaced, but also it is identical that the display screen on multiple well lids around can be made to be played simultaneously
Promotional content, play better the effect of publicity.
Further, the upper surface of the manhole cover body 2 is equipped with display screen 21, and the downside of the manhole lid device, which is equipped with, to be taken the photograph
As head 4, the camera 4 is connected to the display screen 21, and the display screen 21 is for showing captured by the camera 4
Borehole image.In the present embodiment, when rescue personnel reaches scene, the case where in order to more have a clear understanding of underground, Ke Yitong
Display screen 21 is crossed to watch the image of underground, can specify more accurate rescue method in this way, improves rescue effect, and
It can also avoid in rescue operations, be injured caused by trapped person.
There are multiple electronic components, electric energy when in order to guarantee that electronic component uses is optional in above-mentioned manhole cover body 2
Ground, has solar panel on the upper surface of manhole cover body 2, and solar panel is that well lid fills for converting the solar into electric energy
Set power supply.In the present embodiment, battery can have in solar panel, solar panel can be absorbed too when daytime
Positive energy, and convert solar energy into electric energy and be stored in battery, it at night can be the electricity in manhole lid device by battery
Subcomponent is powered, in addition, the solar panel carries out in use, solar panel is low in order to prevent in winter in the north
Temperature it is lower can not normal use, which can use low-temperature resistance material be made, and make solar panel and well lid sheet
It is detachably connected between body 2, facilitates and dismantled.
The embodiment of the invention provides a kind of manhole lid devices, for avoiding staff from being locked in the well head under manhole lid device
In pipeline, the safety of manhole lid device is improved.And in the prior art, when the well lid at well head is closed by mistake, staff
