Embodiment
The utility model discloses a kind of Clearance survey device, so that carry and measure, increase work efficiency.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1, the structural representation of the Clearance survey device that Fig. 1 provides for the utility model embodiment.
The utility model embodiment provides a kind of Clearance survey device, comprises lift-off device 1 and insulating cord 2; Lift-off device 1 can rise in atmosphere; And insulating cord 2 is connected with lift-off device 1.And insulating cord 2 is provided with scale mark 4.
The Clearance survey device that the utility model embodiment provides, in measuring process, connected lift-off device 1 is made vertically to increase by the release of insulating cord 2, insulating cord 2 is driven to rise in lift-off device 1, when the scale mark 4 of on insulating cord 2 arrives formulation position, headroom size can be drawn by other scale marks 4 of insulating cord 2.For the Clearance survey of wire to trees, lift-off device 1 rises, the rising of lift-off device 1 is stopped after the scale mark 4 at the zero point of insulating cord 2 arrives wire, by artificially observing the scale mark 4 tool observes insulating cords 2 such as telescope being positioned at trees tip portion, and then show that wire arrives the headroom size of trees.The Clearance survey device that the utility model embodiment provides, can overcome the woods and block the problem that the visual field or extreme terrain be difficult to measure, also do not need to have a power failure and measure, device is easy to carry, can complete Clearance survey simply and easily, effectively improve work efficiency.
In the present embodiment, the distance of adjacent two scale marks 4 is 500mm ± 1mm.That is, the spacing between adjacent two scale marks 4 is half meter, so that operating personnel observe.Certainly, also can be set to other spacing, introduce no longer in detail at this.
Further, scale mark 4 comprises conventional scale mark and outstanding scale mark, and two kinds of scale marks are arranged in a crossed manner.That is, the scale mark 4 of conventional scale mark both sides is outstanding scale mark, and the scale mark 4 of outstanding scale mark both sides is also conventional scale mark.The spacing of adjacent two outstanding scale marks is 1 meter, and adjacent two conventional scale marks are also 1 meter.Outstanding scale mark can make it be different from conventional scale mark from the aspect such as color or size, so that make it be more conducive to observe.In operating personnel's observation process, whole rice number can be drawn by means of only the outstanding scale mark of observation, then by observing the further accurately headroom size of conventional scale mark.Preferably, the scale mark 4 at zero point is outstanding scale mark.
Carry to further facilitate, the lift-off device 1 in the Clearance survey device that the utility model embodiment provides is balloon, is filled with the gas that gas density is less than atmospheric density in it.Wherein, measuring position can be carried to by after balloon inflation, inflate again after also balloon and aerating device can being carried to measuring position.
Further, the peristome of balloon is closed in one end binding of insulating cord 2.By above-mentioned setting, avoid other setting parts, further simplify Clearance survey device.Also separately the peristome of balloon can be closed, then insulating cord 2 is connected on balloon.Insulating cord 2 directly can be bundled in the peristome of balloon, also can be affixed on top or the sidewall of balloon by the mode such as bonding.
In the present embodiment, gas is helium.The gas density 0.1347kg/m of helium
3, be less than the gas density of air, then after a certain amount of helium is filled with balloon, the density of its ensemble average is still less than the gas density of air, and then makes lift-off device 1 to increase in atmosphere.Also can be filled with other gas in balloon, as hydrogen etc., only need to guarantee that its gas density is less than the gas density of air.
Further, balloon is rubber balloon.Also the material such as plastics or resin can be adopted to make balloon, introduce no longer in detail at this.Preferably, balloon is the rubber balloon of 36 cun, makes to inflate rear diameter and is about 80cm.
Certainly, miscellaneous part also can be adopted as lift-off device 1, as parts such as hot balloons, introduce no longer in detail at this, only need to guarantee that it can be risen in atmosphere by self strength.
In order to reduce the weight of insulating cord 2, so that reduce its impact of rising for lift-off device 1, insulating cord 2 is silk rope; The diameter of insulating cord 2 is less than or equal to 2mm.Due to the lighter in weight of silk, insulating cord 2 weight that the silk that diameter is less than or equal to 2mm is made is also lighter.Also setline etc. can be adopted as insulating cord 2, above-mentioned effect can be reached equally.
The Clearance survey device that the utility model embodiment provides also comprises and is arranged at the Winder 3 of insulating cord 2 away from one end of lift-off device 1.Realized the folding and unfolding of insulating cord 2 by Winder 3, further facilitated and measured operation.
In the present embodiment, Winder 3 has the winding wheel be wound around for insulating cord 2 and the handle driving winding wheel to rotate, and winding wheel is at the uniform velocity discharged by lever operated or reclaimed insulating cord 2.
Preferably, winding wheel is circle wheel, so that make lift-off device 1 stable elevation.Also winding wheel can be set to ellipse, the size of the circle making lever operated release or reclaim insulating cord 2 is fixing, as the circle insulating cord 2 on winding wheel is of a size of half meter, further increases the comfort level of measurement.
In this instructions, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
