Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.Reality based on the utility model
Example is applied, every other embodiment obtained by those of ordinary skill in the art without making creative efforts all belongs to
In the range of the utility model protection.
A kind of screw-type monitoring point protective device, as shown in Figs 1-4: including cylindrical protective body 1, protection cap 2, locking machine
Structure, four fixed ears 4, spring 5, measurement lid 9, bolt 10 and pull ring 11.
Cylindrical protective body 1 is hollow cylinder, and protection cap 2 is the lid cooperated with cylindrical protective body 1.Protection cap 2 with
The cooperation of cylindrical protective body 1 constitutes a hollow cylinder, plays good protective action to monitoring point.
Retaining mechanism includes external screw thread 3 and internal screw thread 12.
Wherein, external screw thread 3 is arranged on 1 side wall of cylindrical protective body, and internal screw thread 12 is arranged on 2 inner wall of protection cap.Outside
The height of screw thread 3 and the height of internal screw thread 12 are equal, and external screw thread 3 is threadedly engaged with internal screw thread 12 to be connect to protection cap 2 and circle
Fixation between cylindricality protection body 1.Also, it is connected through a screw thread mode between cylindrical protective body 1 and protection cap 2 and connects and be convenient for
The disassembly of the two, it is easy to disassemble and replace when one of both damage.
Four fixed ears 4 are in array distribution on 1 side wall of cylindrical protective body, with cylindrical protective body 1 side wall one
Molding connection.The bottom surface of four fixed ears 4 is overlapped with the bottom surface of cylindrical protective body 1.Run through in four fixed ears 4 and offers
Fixation hole 6.Manually adjusting protective device makes monitoring site in 1 center of cylindrical protective body, with setscrew through solid
Determine the fixation hole 6 on ear 4, so that protective device is fixed on the basal plane of monitoring point place, is convenient for monitoring point monitoring.
Spring 5 is arranged in cylindrical protective body 1, and one end of spring 5 is fixedly connected on 2 bottom of protection cap, spring 5 it is another
One end is free end, plane where free end is against monitoring point.The height of spring 5 is greater than the height of cylindrical protective body 1, bullet
Spring 5 is in compressive state.
When dismantling protection cap 2, the elastic force of spring 5 helps to back out protection cap 2, plays the role of good power-assisted.And
In normal use, protection cap 2 is covered by soil, so that spring 5 is difficult to play elastic force effect, to protect protection cap 2.
Square hole 1 and square hole 28, the top surface of square hole 1 and the top surface of protection cap 2 are offered at the top of protection cap 2
It is overlapped, the bottom surface of square hole 28 is overlapped with the bottom surface of protection cap 2.The central axes of square hole 1 and square hole 28 are overlapped and it
Diagonal line is parallel, and the length and width of square hole 1 is respectively greater than the length and width of square hole 28.Square hole 1 and rectangular
The sum of the height in hole 28 is equal to the thickness of 2 roof of protection cap.When present apparatus normal use, measurement lid 9 carries one 7 bottom of square hole
On 2 end face of protection cap in portion.
Lid 9 is measured with square hole 1 one is hinged at, and measures length, width and the height and square hole 1 of lid 9
Length, width and height be equal to each other.Individually measurement lid 9 is set in protection cap 2, convenient for being measured to monitoring point,
It avoids and unloads the cumbersome of protection cap 2 in traditional measurement method, directly opening measurement lid 9 can measure, side easy to operate
Just.
10 activity of bolt is connect through measurement lid 9 and with the end-face helical of the protection cap 2 where one 7 bottom surface of square hole.It draws
One end face of ring 11 and measurement lid 9 is rotatablely connected, and is used to measure the lifting of lid 9.
The setting of bolt 10 effectively overcomes tradition so that being well fixed between measurement lid 9 and protection cap 2
Measurement lid is easily pulled by external force so that the defect that monitoring point is destroyed in device.It is only needed when being detected using the present apparatus
Bolt 10 is turned upwards, so that bolt 10 is detached from 2 end face of protection cap, pulls pull ring 11 that can will measure 9 pull-up of lid and examines
It surveys, is arranged by this, effectively overcomes traditional detection plate because weight is larger and be difficult to open defect.
When being monitored burial and construction, the depth of excavation 12cm or so more than normal depth, when mixed mud pedestal pours
After the completion of building, the depth of reserved 12cm or so is used to protection device for installing, after the installation is completed, is covered with the thick native hack of general 3cm
Lid, is better able to monitoring for protection point by artificial destruction in this way.
The utility model is a kind of screw-type monitoring point protective device, solve artificial destruction, environmental corrosion etc. it is various because
Element causes monitoring site that cannot continue as the problem of engineering safety provides monitoring data.The fixation that cylindrical protective body passes through bottom
Ear is fixed on monitoring point with setscrew, and monitoring site is in cylindrical protective body center.Protection cap passes through cylindrical anti-
It couples and separates after the screw thread of watch box upper end and the screw thread rotation certain angle on the inside of protection cap.Bolt is backed out, pull ring, side are pulled
Just it opens detection lid and carries out deformation monitoring.
