Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Referring to Fig. 1, a kind of dedicated magnetic switch of well lid, including mounting base 2, tongue tube 3, magnet 4, rotatable lamella 5, connection
Axis 6.This magnetic switch is installed on the bottom surface of well lid 1 and the junction in 7 support face of cover seat of manhole, chimeric with cover seat of manhole 7 by well lid 1
The automatic switchover of magnetic switch open/close states is realized in the variation of position, avoids directly contacting with rainwater, sludge etc., it can be achieved that well
Dust and moisture anti-corrosion effect.Well lid 1 is usually regular circle or square structure, therefore this magnetic switch is mountable to well lid 1
Adjustment is set without being embedded in the laggard line position of cover seat of manhole 7 to well lid 1 in any one orientation of bottom surface, adaptable.
Mounting base 2 is fixed on the bottom surface of well lid 1, and the bottom end of mounting base 2 is rotatably connected to rotatable lamella 5.Such as Fig. 2 institute
Show, in the present embodiment, mounting base 2 is sheet metal part, and the bottom surface both side of mounting base 2 is respectively arranged with flank 21, two flanks
Connecting shaft 6 is connected between 21, connecting shaft 6 runs through rotatable lamella 5.Bottom surface one end of mounting base 2 is provided with vertical flange 22, turns over
Side 22 leans on the side of near magnet 4 to fix, and there are two tongue tubes 3.Using two 3 concurrent workings of tongue tube, when a tongue tube 3 loses
The normal work of switch is not influenced when effect, guarantees the reliability of switch work.
Rotatable lamella 5 is fixed with magnet 4 close to one end of tongue tube 3.Preferably, the cross sectional shape of rotatable lamella 5 is in " Z " type knot
Structure.When well lid 1 is embedded in cover seat of manhole 7, the support face of cover seat of manhole 7 acts on the outer end of rotatable lamella 5, makes the outer end of rotatable lamella 5
It is fixed on the delivery position of well lid 1 and cover seat of manhole 7；After rotatable lamella 5 rotates, magnet 4 on the other end is then to moving down
The side for moving and being positioned at tongue tube 3 is placed in tongue tube 3 in the high-intensity magnetic field of magnet 4.
When to guarantee that well lid 1 is separated with cover seat of manhole 7, rotatable lamella 5 is able to drive the smooth return of magnet 4, so that tongue tube 3 is not
In high-intensity magnetic field in magnet 4, using the combination of any one following mode or any several ways:
(a) mounting base 2 is using sheet metal component made of ferrimagnet.Using such mode, when well lid 1 and cover seat of manhole 7
When separation, rotatable lamella 5 is in state free to rotate, then the magnetic field of magnet 4 can be adsorbed in the bottom surface of mounting base 2 naturally, real
The return of existing rotatable lamella 5.Meanwhile the spacing between 2 bottom surface of magnet 4 and mounting base need to meet condition: first is that well lid 1 and cover seat of manhole
7 when not separating, and the bottom surface of mounting base 2 is in the magnetic field range of magnet 4, and the attraction foot that the magnetic field generates mounting base 2
So that rotatable lamella 5 can be in the smooth return of free state.
(b) mounting base 2 is using sheet metal component made of nonferromugnetic material, and the bottom surface of mounting base 2 is fixed with positioned at magnet 4
The magnetic sheet of top.Using such mode, when well lid 1 is separated with cover seat of manhole 7, rotatable lamella 5 is in state free to rotate, then magnetic
Iron 4 can be adsorbed on the bottom surface of mounting base 2 under the attraction effect of magnetic sheet, realize the return of rotatable lamella 5.Such mode makes
Simple process, production cost is low, and functional reliability is high, the scheme preferentially used for the present embodiment.
(c) junction of rotatable lamella 5 and mounting base 2 is provided with torsional spring.Using such mode, when well lid 1 is embedded in cover seat of manhole 7
When interior, rotatable lamella 5 is rotated, while torsional spring accumulation of energy generates torsion；When well lid 1 is separated with cover seat of manhole 7, rotatable lamella 5 is in can be certainly
By rotary state, then rotatable lamella 5 realizes return under the restoring force effect of torsional spring.
(d) top surface of rotatable lamella 5 is connected with tension spring by one end of near magnet 4, and the other end of tension spring is fixed on mounting base 2
Bottom surface.Using such mode, when well lid 1 is embedded in cover seat of manhole 7, rotatable lamella 5 is rotated, while tension spring is stretched and generates pulling force；
When well lid 1 is separated with cover seat of manhole 7, rotatable lamella 5 is in state free to rotate, then rotatable lamella 5 is acted in the restoring force of tension spring
Lower realization return.
It is connected when the utility model is used, being equipped in advance in the bottom surface of cover seat of manhole 7 with the control equipment of monitoring center
The signal wire connect, the signal wire are connect with the conducting wire 8 at 3 both ends of tongue tube, and well lid 1 is monitored by the working condition of tongue tube 3
Working condition.After well lid 1 is embedded in cover seat of manhole 7, as shown in figure 3, rotatable lamella 5 is clamped and is determined by well lid 1 and cover seat of manhole 7
, the magnet on rotatable lamella 5 is moved at tongue tube 3, is placed in tongue tube 3 in the high-intensity magnetic field of magnet 4, tongue tube 3 is by magnetic
The magnetic conduction of iron 4 is acted on and is connected, and realizes the conducting effect of magnetic switch.
After well lid 1 is pried open, well lid 1 is separated with cover seat of manhole 7, as shown in figure 4, at this time rotatable lamella 5 be in be freely rotated
State, magnet 4 and mounting base 2 it is attracting (above-mentioned a scheme), 5 return of rotatable lamella, tongue tube 3 then not by the magnetic fields of magnet 4 and
It disconnects, realizes the cut-out function of magnetic switch.The control equipment being connected at this time with tongue tube 3 will receive feedback signal, thus real
It now alerts, and quick lock in is stolen the location information of well lid 1.
The utility model structure is simple, and cost is relatively low, easy to install and use, without becoming to existing manhole cover structure
The reliably monitoring, it can be achieved that well lid working condition is moved, there is good practical value.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
