Description

Multifunctional well cover
Technical field
The present invention relates to a kind of Multifunctional well cover.
Background technology
Nowadays the well lid used mostly is cast iron quality class well lid, and this type of well lid is not reported to the police and anti-theft feature, is thus susceptible to stolen and cannot follow the trail of well lid.In addition the anti-fall performance of tradition well lid is the most poor, generally uses nylon wire and is placed on the hook of well inwall, and owing to nylon wire is perishable, bearing capacity is poor, and due to the most washed away loss of nylon wire quality, thus lose anti-drop function, there is potential safety hazard.
Summary of the invention
The invention provides a kind of Multifunctional well cover, when well lid is illegally opened, possess warning function.
In order to solve the problems referred to above, the technical solution adopted in the present invention is such, a kind of Multifunctional well cover, including the pressure transducer being arranged on well lid and mechanical delivery device, described mechanical delivery device includes the roller that push rod is connected with this putting back-end, and contact with roller and promote the movable cam of push rod, described pressure transducer is located at the dead ahead of push rod and contacts with push rod front end, this pressure transducer is connected with warning concentrator, and warning concentrator is connected with client.
Described cam is disc cam, and this disc cam is rotated by the rotary shaft passing perpendicularly through dish row cam, and the two ends of this rotary shaft and the shell supporting rotary shaft are rotationally connected, and shell fixes with well lid.
In order to prevent well lid stolen, described well lid is fixed by anti-theft screw and spring washer with well seat.
In order to prevent people or object from falling down-hole, described Multifunctional well cover also includes anti-fall device, the anti-fall dividing plate that the profile that includes this anti-fall device matches with well head interior shape and the bracing frame of the anti-fall dividing plate of multiple supports along the setting of well inwall circumference, described anti-fall dividing plate is arranged at the lower section of well lid, bracing frame is arranged at the lower section of anti-fall dividing plate, anti-fall dividing plate is detachably connected with bracing frame, and bracing frame is fixed with well inwall by securing member.
Observing down-hole situation for convenience, described anti-fall dividing plate is netted anti-fall dividing plate, and this anti-fall dividing plate is made up of PV material.
Beneficial effect:
(1) compared to traditional well lid before, by increasing mechanical delivery device, pressure transducer, controller and alarm, well lid is made to possess warning function.When illegal open manhole cover, cam rotates, so that push rod produces displacement, triggers alarm device, possesses warning function;When staff needs open manhole cover, only need well lid application open command, pressure inductor break-off, can will not trigger warning with normal construction.
(2) compared to tradition well lid before, the well lid of the present invention possesses anti-theft feature, uses anti-theft screw to be connected fixing between well lid with well seat, and anti-theft screw can only use special fixture can Unscrew well lid, safety raising, it is to avoid well lid is the most stolen.
(3) compared to using nylon anti-drop net before, the present invention anti-fall performance be greatly improved, safety is high.Using the anti-fall dividing plate made of PV material, allowable stress is big, corrosion-resistant, be difficult to be lost by water punching, is significantly better than nylon anti-drop net.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the structural representation that well lid fixes with well seat;
Fig. 3 is the structural representation of anti-fall device.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment is only used for explaining the present invention, is not intended that limiting the scope of the present invention.
See Fig. 1, a kind of Multifunctional well cover, including the pressure transducer 2 being arranged on well lid 1 and mechanical delivery device, described mechanical delivery device includes the roller that push rod 3 is connected with this push rod 3 rear end, and contact with roller and promote the movable cam 4 of push rod 3, described pressure transducer 2 is located at the dead ahead of push rod 3 and contacts with push rod 3 front end, and this pressure transducer is connected with warning concentrator, and warning concentrator is connected with client.
Described cam 4 is disc cam, and this disc cam is rotated by the rotary shaft 5 passing perpendicularly through dish row cam, and the two ends of this rotary shaft 4 and the shell 6 supporting rotary shaft are rotationally connected, and shell 6 fixes with well lid 1.
This mechanical delivery device is disc cam with pushing bar of roller of linear motion along the axis, radius of roller rr=10mm, when cam rotates 0-30 °, is in rise stage, pushrod advances 30mm;When cam rotates 30 °-90 °, being in remote rest stage, push rod is slack;When cam half-twist-180 °, being in the backhaul stage, push rod declines 30mm;When cam rotates 180 °-360 °, being in remote rest stage, push rod is slack.
When well lid is illegally opened, cam rotates, the push rod caused produces displacement, when pressure transducer detects the effect that push rod is applied, signal is passed to warning concentrator, thus triggering warning concentrator, the wireless alarm signal accepted is passed through and processes to client by warning concentrator, thus plays the effect of burglar alarm;When staff needs open manhole cover, apply for open command, client send open command by being wirelessly transmitted to warning concentrator, well lid inductive terminations is controlled by warning concentrator so that it is break-off, can be with normal construction.
Pressure transducer uses 7.2V lithium battery power supply, the most in a dormant state, can save electric quantity consumption, reduce battery altering frequency.
Described client is preferably PC or hand-held PDA.
Participating in Fig. 2, in order to prevent well lid stolen, described well lid 1 is fixed by anti-theft screw 8 and spring washer 9 with well seat 7.Preferably, described anti-theft screw 8 uses square toes flush end holding screw, with reference to mechanical design handbook GB/T821-1988, material is steel, and surface is processed as zinc-plated oxidation, and this square toes flush end holding screw contact area is big, for pushing up the big part of hardness, the face of holding out against is plane, it is adaptable to well seat.
In order to prevent people or object from falling down-hole, described Multifunctional well cover also includes anti-fall device, as shown in Figure 3, the anti-fall dividing plate 10 that the profile that includes this anti-fall device matches with well head interior shape and the bracing frame 11 of the anti-fall dividing plate of multiple supports 10 along the setting of well inwall circumference, described anti-fall dividing plate 10 is arranged at the lower section of well lid 1, bracing frame 11 is arranged at the lower section of anti-fall dividing plate 10, anti-fall dividing plate 10 is detachably connected with bracing frame 11, the most anti-fall dividing plate 10 is connected with bracing frame 11 by rotating dog 13, bracing frame 11 is fixed with well inwall by securing member, in the present embodiment, securing member is steady pin 12.
Preferably, rotating dog 13 uses the taper bolt of GB GB/T 117-2000, and material is 45 steel, surface oxidation treatment;Holding pin 12 uses the straight pin material of GB GB/T 119.1-2000 to be austenitic stainless steel, and surface is simple process.
Observing down-hole situation for convenience, described anti-fall dividing plate 13 is netted anti-fall dividing plate.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
