Abstract
Protection alarm manhole well lid is the communal facility of urban road.Comprise the main shaft lid (1) that can be placed on base well well head, below main shaft lid, be provided with the auxiliary shaft lid (2) that can be fixed on the borehole wall; Described auxiliary shaft covers and arranges bar shape trench hole (3); Be provided with rod member (4), the middle part of rod member connects a minor axis (5), and the two ends of described minor axis are connected to auxiliary shaft and cover on the bearing (2a) of bar shape trench hole both sides; Described rod member is positioned at described bar shape trench hole, and epimere is warning rod, and hypomere is gravity rod, and under the effect of described gravity rod, rod member can produce rotation relative to bar shape trench hole, and warning is protected on warning rod and the extended road surface of rod member epimere.There is structure simple, can manufacturing cost be reduced, rod member firm and durable, the features such as functional performance is reliable.
Description
Technical field
The utility model relates to the public utility of urban road, specifically the protection alarm manhole well lid of a kind of urban road Ji Jing.
Background technology
The road surface manhole of urban road Ji Jing (as Ji Jing such as sewers), because damaging fragmentation or being removed, losing, causing damage by initiation passing cars, especially damaging because falling into Ji Jing passing pedestrian.For strengthening protection warning, a kind of sewer base well manhole lid device is disclosed in existing technology, this manhole lid device comprises the main shaft lid that can be placed on base well well head, the auxiliary shaft lid that can be fixed on the borehole wall is provided with below main shaft lid, auxiliary shaft covers and is provided with vertical tubulose cover for seat, tubulose cover for seat is built-in with warning spring, when main shaft lid is placed on base well well head, due to the Action of Gravity Field of main shaft lid, warning spring is compressed in tubulose cover for seat, when main shaft cover is removed or is lost, road surface is stretched out in the top of warning spring namely, passing vehicles or pedestrians are warned, even if pedestrian falls into well head, auxiliary shaft lid can play supporting role, personal safety is caused to avoid falling in sewer.But in use, warning spring is in confined state all the time, easily causes spring member tired, adds the reason that may produce corrosion and affect the functional performance of warning spring member, and its tubulose sleeve member, its manufacturing cost will be increased.
Summary of the invention
The utility model proposes a kind of protection alarm manhole well lid improving functional performance, and simplify structure, can manufacturing cost be reduced, and warning component is durable.
The technical solution of the utility model:
Comprise the main shaft lid that can be placed on base well well head, below main shaft lid, be provided with the auxiliary shaft lid that can be fixed on the borehole wall;
Described auxiliary shaft covers and arranges bar shape trench hole;
Be provided with rod member, the middle part of this rod member connects a minor axis, and the two ends of described minor axis are connected to auxiliary shaft and cover on the bearing of bar shape trench hole both sides, and described rod member is positioned at described bar shape trench hole, and epimere is warning rod, and hypomere is gravity rod;
Under the effect of described gravity rod, described rod member can produce rotation relative to bar shape trench hole, described warning rod and extended road surface.
The state of the utility model use procedure is: when main shaft lid is placed on base well well head, due to the Action of Gravity Field of main shaft lid, described rod member and rotation are positioned at the below of main shaft lid to heeling condition, when main shaft cover is removed or is lost, due to the effect of the gravity rod of rod member hypomere, the automatic rotation of rod member is to vertical state, and namely the warning rod of rod member epimere stretches out road surface.
Technique effect of the present utility model: due to auxiliary shaft cover be provided be positioned at bar shape trench hole and swinging rod member, due to the effect of the gravity rod of hypomere, when main shaft cover is removed or is lost, rod member and automatic rotation are to vertical state, the warning rod of rod member epimere and extended road surface, protected warning to passing vehicles or pedestrians; Be positioned at bar shape trench hole and swinging rod member, structure is simple, and can reduce manufacturing cost, utilize the Action of Gravity Field of the gravity rod of rod member hypomere to make the warning rod of rod member epimere stretch out road surface, rod member firm and durable, functional performance is reliable.Described auxiliary shaft lid can support the pedestrian that falls into well head equally and avoid falling in sewer and cause personal safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model, in analysing and observe state, and is defined as Figure of abstract;
Fig. 2 is the A-A schematic enlarged-scale view of Fig. 1;
Fig. 3 is for after removing main shaft lid, and the warning rod of rod member epimere stretches out the alert status on road surface.
Detailed description of the invention
See accompanying drawing.Comprise the main shaft lid 1 that can be placed on base well 7 well head, below main shaft lid 1, be provided with the auxiliary shaft lid 2 that can be fixed on the borehole wall; Auxiliary shaft lid 2 is arranged bar shape trench hole 3; Be provided with rod member 4, the middle part of rod member 4 connects a minor axis 5, and the two ends of described minor axis are connected to auxiliary shaft and cover on the bearing 2a of bar shape trench hole both sides, and described rod member 4 is positioned at described bar shape trench hole 3, and the epimere of rod member 4 is warning rod 4a, and hypomere is gravity rod 4b; With minor axis 5 and minor axis 5 and bearing 2a correlation in the middle part of rod member 4, when being fixedly connected with minor axis in the middle part of rod member 4, minor axis 5 can produce relative to bearing 2a and rotate; When minor axis 5 is fixed on bearing 2a, rod member 4 can produce rotation around minor axis 5; When main shaft cover is removed, under the effect of described gravity rod, described rod member can produce rotation relative to bar shape trench hole, warning rod and extended road surface.
The warning rod 4a of rod member 4 epimere pays the utmost attention to employing tubular structure, and warning rod outside wall surface arranges the warning color segment meeting relevant regulations, and fluorescent powder coating.When warning rod 4a adopts tubular structure, to be conducive to the gravity rod 4b forming hypomere, namely gravity rod 4b can be solid rod construction, and pass through Mass Calculation, guarantee gravity rod 4b to be enough to make rod member 4 produce rotation and meet warning rod 4a to stretch out road surface, meanwhile, guarantee that warning rod 4a has enough eye level after stretching out road surface.The magnitude setting of rod member 4 is advisable with 2-3 part.
The enforcement structure of described gravity rod 4b except above-mentioned points, also can be other form of structure, as shown in the figure on gravity rod 4b, balancing weight 6 is set; Gravity rod 4b or be tubular structure, during for tubular structure, filling as metallic particles or cement or the large material of sand grains isodensity in this hollow section, and end plate is set in the lower end of hollow section and prevents from managing interior content leaks, to guarantee that rod member 4 can produce rotation, make warning rod 4a be enough to stretch out road surface and there is enough eye level.Auxiliary shaft lid 2 arranges some drainage holes 8.During installation, the main shaft lid component aboveground with auxiliary shaft lid and base is reliably connected.
The non-metallic material that the material of described auxiliary shaft lid 2 and rod member 4 can adopt value cheaper and durable.
Various enforcement structure described in this manual and scope of the present utility model is all belonged to any distressed structure of technical solutions of the utility model.
