Abstract
The invention relates to a road manhole cover hydraulic pressure jacking warning device, which is characterized by comprising a manhole cover and a manhole cover seat ring used for placing the manhole cover, wherein a triggering unit is arranged between the manhole cover and the manhole cover seat ring, and is connected with a luminous floating object capable of floating on the water surface. The road manhole cover hydraulic pressure jacking warning device has the advantages that the structure is simple, the luminous floating object is utilized for warning passers-by to be careful on a deep manhole with the opened manhole cover.
Description
Technical field
The present invention relates to a kind of manhole hydraulic pressure and back down alarming device.
Background technology
Well lid in road is mainly used in the deep-well on defiladed route, according to the difference of each subterranean pipe line, some deep-wells are as waterway pipe, cable tubing or gas pipeline etc., deep-well be provided with the maintenance that is beneficial to pipeline, yet at some in particular cases, heavy rain or human factor cause well lid to remove and cause personnel or object to fall into deep-well, or are pressed and impact and jack-up in deep-well, and the appearance of these phenomenons all will bring huge potential safety hazard to people's trip.
Summary of the invention
In view of this, the object of this invention is to provide a kind of manhole hydraulic pressure and back down alarming device.
The present invention adopts following scheme to realize: a kind of manhole hydraulic pressure backs down alarming device, it is characterized in that: comprise that a well lid and is for placing the well lid seat ring of described well lid, between described well lid and well lid seat ring, be provided with a trigger element, described trigger element connection one may float on the luminous floating thing of the water surface.
In an embodiment of the present invention, be provided with one for preventing the grid of human body whereabouts in described well lid seat ring, on the inside wall of described well lid seat ring, along being circumferentially laid with the groove of at least two, described grid perimembranous correspondence is provided with the projection of the location of matching with groove.
In an embodiment of the present invention, described groove is L-type.
In an embodiment of the present invention, described L-type bottom portion of groove has stair-stepping terrace, between described projection and grid, has reinforcing rib.
In an embodiment of the present invention, described grid is round.
In an embodiment of the present invention, described in may float on the water surface luminous floating thing comprise that one may float on the shell body of the water surface, in described shell body, be provided with a luminescence unit and a driver element, described driver element connects described trigger element.
In an embodiment of the present invention, the described luminous floating thing that may float on the water surface comprises that one may float on the shell body of the water surface, in described shell body, be provided with a control module, described control module connects a driver element, a radio-cell and described trigger element, and described driver element connects a luminescence unit.
Compared with prior art, the present invention has following beneficial effect: the present invention is simple in structure, utilize the deep-well of the careful opened well lid of luminous floating thing warning passerby, and utilize L-type groove to coordinate with projection, grid is fixed in the well lid seat ring of well lid below, can prevent that well lid from falling, in addition, the present invention utilizes the mode of different terraces, can prevent that the gas of below from impacting and causing grid by the situation of jack-up simultaneously, has market prospects widely.

The specific embodiment
For making object of the present invention, technical scheme and advantage clearer, below will, by specific embodiment and relevant drawings, the present invention be described in further detail.
As shown in Figure 1, the invention provides a kind of manhole hydraulic pressure and back down alarming device, comprise that a well lid 10 and is for placing the well lid seat ring 20 of described well lid, between described well lid 10 and well lid seat ring 20, be provided with a trigger element, described trigger element connection one may float on the luminous floating thing 30 of the water surface.
As Figure 2-3, in described well lid seat ring 20, be provided with one for preventing the grid 40 of human body whereabouts, on the inside wall of described well lid seat ring 20, along being circumferentially laid with the groove 210 of at least two, described grid 40 perimembranous correspondences are provided with the projection 410 of the location of matching with groove.
As shown in Figure 4, described groove is L-type, and groove has stair-stepping terrace, and described projection 410 cross sections are rectangular.Between projection 410 and grid 40, have reinforcing rib, described grid is round.
During use, the projection 410 of grid 40 is put into after matching with the groove of well lid seat ring 20 210, rotation, makes projection fall to the second terrace in the deadweight of grid 40 afterwards, so both can guarantee that the well lid of top cannot fall also can guarantee when there being deep-well below to have gas ejection can not make grid 40 jack-up.
As shown in Figure 5, described in may float on the water surface luminous floating thing comprise that one may float on the shell body of the water surface, in described shell body, be provided with a luminescence unit and a driver element, described driver element connects described trigger element.After well lid backs down, trigger element trigger drive unit drives luminescence unit luminous, to reach warning function.
As shown in Figure 6, the described luminous floating thing that may float on the water surface comprises that one may float on the shell body of the water surface, in described shell body, be provided with a control module, described control module connects a driver element, a radio-cell and described trigger element, and described driver element connects a luminescence unit.After well lid backs down, trigger element trigger control unit, it is luminous that control module is controlled drive unit drives luminescence unit, to reach warning function, meanwhile, control module is controlled radio-cell this alarm signal is sent to remote supervisory center, is beneficial to better supervise.
Above-listed preferred embodiment; the object, technical solutions and advantages of the present invention are further described; institute is understood that; the foregoing is only preferred embodiment of the present invention; not in order to limit the present invention; within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
