Abstract
The utility model relates to a portable wind shield for the underground survey, which comprises an arc-shaped wind shield body. The profile of the cross section of the arc-shaped wind shield body is not greater than three fourth of a circle. The wind shield body is connected with telescopic supporting legs used for regulating the overall height of the wind shield, so that the wind shield can be applied in different underground conditions to keep out the wind during the survey. The wind shield body is of an annular structure with an opening and is capable of keeping out the wind blowing from three directions. Meanwhile, the supporting legs are adjustable in height, so that the supporting legs are adaptive to uneven geographical conditions in tunnels. Moreover, the portable wind shield is convenient to carry about and move, and facilitates the underground survey work.
Description
Technical field
It is the device that plumb bob keeps out the wind that the utility model relates to a kind of in the time carrying out underground survey or setting-out, and the portable deep bead of especially a kind of underground survey belongs to field of mining.
Background technology
In underground survey when centering, down-hole wind-force can make plumb bob amplitude of fluctuation excessive, thereby cause centering difficulty, so need to adopt deep bead to keep out the wind, but existing deep bead is generally iron structure, too heavy, should not carry, bring very heavy burden to survey crew, existing deep bead height is fixed in addition, is difficult to adapt to the rugged actual state in down-hole; Existing deep bead is plane, down-hole variable direction, and the effect of keeping out the wind neither be very desirable.
Utility model content
In order to address the above problem, the utility model proposes the portable deep bead of a kind of underground survey, deep bead body design is the loop configuration with opening, can block the wind comes from of three directions, and design height-adjustable supporting leg, the geographical conditions that rise and fall to adapt to tunnel height, and be convenient for carrying and move, for the surveying work of down-hole is provided convenience.
The utility model solves the technical scheme that its technical matters adopts: the portable deep bead of a kind of underground survey, comprise that an xsect is the arc wind board main body that is not more than 3/4 circle, described deep bead main body connects telescopic supporting leg, can be in order to regulate the overall height of deep bead, the measurement adapting under the different situations of down-hole is kept out the wind.
Described arc wind board main body is circumferentially divided at least three sections along it, middle one section of canned paragraph deep bead, both sides be active segment deep bead, described active segment and canned paragraph deep bead adopt the connected mode being slidably matched, can regulate the size of the body openings of keeping out the wind, regulate according to subsurface environment and wind direction, realize comprehensive keeping out the wind, do not affect again normal measurement.
Described supporting leg is at least made as three, comprise supporting leg body and the roller that is installed on supporting leg body bottom, the canned paragraph of described supporting leg body is fixedly connected with active segment deep bead with canned paragraph deep bead respectively, and the telescopic section of described supporting leg body can be carried out length adjusting according to the height in tunnel.
The utility model can adopt the plastic production that hardness is good and light, also can be made by light-weight metals such as aluminium alloys, alleviates its weight, is convenient for carrying.
The beneficial effects of the utility model are: the portable deep bead of a kind of underground survey, deep bead body design is the loop configuration with opening, can block the wind comes from of three directions, and design height-adjustable supporting leg, the geographical conditions that rise and fall to adapt to tunnel height, and be convenient for carrying and move, for the surveying work of down-hole is provided convenience.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing 1 is the structural representation of the portable deep bead of a kind of underground survey.
Accompanying drawing 2 is vertical views of the portable deep bead of underground survey.
In figure, 1. deep bead main body, 1-1. canned paragraph deep bead, 1-2. active segment deep bead, 2. supporting leg, 2-1. supporting leg body, 2-2. roller.
Embodiment
In the accompanying drawings, the portable deep bead of a kind of underground survey, comprises that an xsect is the arc wind board main body 1 that is not more than 3/4 circle, and described deep bead main body 1 connects telescopic supporting leg 2, can be in order to regulate the overall height of deep bead, the measurement adapting under the different situations of down-hole is kept out the wind.
Described arc wind board main body 1 is circumferentially divided at least three sections along it, middle one section of canned paragraph deep bead 1-1, both sides be active segment deep bead 1-2, described active segment 1-2 and canned paragraph deep bead 1-1 adopt the connected mode being slidably matched, can regulate the size of main body 1 opening that keeps out the wind, regulate according to subsurface environment and wind direction, realize comprehensive keeping out the wind, do not affect again normal measurement.
Described supporting leg 2 is at least made as three, comprise supporting leg body 2-1 and the roller 2-2 that is installed on supporting leg body 2-1 bottom, the canned paragraph of described supporting leg body 2-1 is fixedly connected with active segment deep bead 1-2 with canned paragraph deep bead 1-1 respectively, and the telescopic section of described supporting leg body 2-1 can be carried out length adjusting according to the height in tunnel.
The utility model can adopt the plastic production that hardness is good and light, also can be made by light-weight metals such as aluminium alloys, alleviates its weight, is convenient for carrying.
When use, according to the tunnel situation of wind direction and measured place, regulate the height of supporting leg 2 and the openings of sizes of deep bead main body 1, plumb bob is placed in deep bead main body 1, prevent that it is rocked by windage, affect measurement result, if need continuous coverage, can utilize roller that deep bead is moved to next place.The not used time, supporting leg 2 can be shunk and fold and deep bead main body 1 is closed up, be convenient for carrying.
