Abstract
The utility model discloses a laser quadrat setting-up device which can emit red laser along the directions of the arrises of a rectangular pyramid array and has LED (light-emitting diode) lamps for illumination. The device is internally provided with a set of red laser diodes (1), a set of LED lamps and the like. Red laser beams emitted from four red laser diodes form a rectangular pyramid array, and the height of the rectangular pyramid array is half of the length of a side of the foursquare undersurface. The set of red laser diodes and the set of LED lamps are respectively supplied with power by two double-AA-battery sets and controlled by two independent switches. The laser quadrat setting-up device is mainly used for setting up frutex quadrat, herbal quadrat and renewed quadrat in survey of forest ecology. Compared with the prior method of setting up quadrat by steel tape or tape, setting up quadrats by the laser quadrat setting-up device is convenient for operating. The laser quadrat setting-up device can reduce the error of setting up quadrats and improve the efficiency of field work. And the LED lamps can offer illumination at night.
Description
Technical field
The measuring equipment of sample prescription particularly utilized red laser that the device of sample prescription is set when the utility model related to forest ecology shrub, draft and seedling investigation.
Background technology
Forest ecology need be provided with the shrub sample prescription of 5m * 5m, the draft sample prescription of 1m * 1m and the nursery stock of 2m * 2m and upgrade sample prescription for the floristics of investigating shrub and draft, quantity and height and nursery stock new situation more.It all is with 5m steel tape or 30m tape measure that sample prescription is set at present, and the problem that steel tape and tape measure are provided with sample prescription is that error is big and efficient is low:
(1), need measure 4 limits of sample prescription respectively, owing to the bad control of angle between the sideline causes the 4 limit shapes that 4 limits surround and non-square has than mistake if use steel tape.(2) if sample prescription is set with tape measure, same since between the sideline angle control inaccurate what obtain at last may be the girth sample prescription determined and non-square, need in addition that 2 people are above to fence up sample prescription with tape measure earlier, tape measure is accepted after waiting sample prescription to investigate again, efficient is low like this.(3) be provided with in the sample prescription process and may cause destruction to a certain degree to cause the investigation result deviation with steel tape and tape measure the sample prescription plant.(4) generally with steel tape and tape measure the correction that sample prescription is not all considered the gradient is set, this has also caused error.
Summary of the invention
Increase work efficiency in order to reduce the sum of errors that sample prescription is set when forest ecology is investigated, a kind of laser that the utility model provides can solve sample prescription easily problem is set.
Technical solutions of the utility model are: (1) device is inner to be made of red laser diode group, LED lamp group, 2 AA electric battery and 2 power switches; (2) the red laser diode group is connected with 1 power switch with 1 AA electric battery, and LED lamp group is connected with other 1 power switch with other 1 AA electric battery; (3) 4 of the laser diode group red laser diode are placed along positive rectangular pyramid hypotenuse, and the height of this rectangular pyramid is half of the positive square length of side in bottom surface.
The beneficial effects of the utility model are that 4 red lasers along positive rectangular pyramid emission can mark 4 angle points of ground sample prescription fast, thereby finish the sample prescription setting, have reduced error, have reduced the destruction to the sample prescription plant, have improved field work efficient.
Description of drawings
Fig. 1 is a front view of the present utility model.Fig. 2 is a side view of the present utility model.Fig. 3 is the utility model circuit diagram.Fig. 4 is provided with the sample prescription synoptic diagram for the utility model field.
Among the figure, 1. red laser diode group, 2.LED lamp group, 3. red laser diode electric battery, 4.LED lamp electric battery, 5. red laser diode power switch, 6.LED lamp power switch, 7. bonnet, 8. annulus.
Embodiment
When sample prescription is set, install red laser diode electric battery (3) and LED lamp electric battery (4), the bonnet (7) of screwing on, hand-held annulus (8), allow it hang down naturally, open red laser diode power switch (5), red laser diode electric battery (3) is red laser diode group (1) power supply, send 4 red lasers along positive rectangular pyramid direction, use device is to the length of side a (shown in Figure 4) of the height h control sample prescription on ground, draft square sample prescription such as length of side a=2m will be set installs overhead height h=1m so, shines 4 angle points that red point is exactly a sample prescription on the ground.Sample prescription is turned off red laser diode power switch (5) after setting completed.
When as night illumination, turn on LED lamp power switch (6) LED lamp group (2) is lighted, press LED lamp power switch (6) when not required once more and turn off power supply.
Claims (2)
1. laser sample prescription instrument is a kind ofly can and have the device of LED lamp illumination concurrently along positive rectangular pyramid direction emission red laser, device is inner to be made of red laser diode group, LED lamp group, 2 AA electric battery and 2 power switches, it is characterized in that: the red laser diode group is connected with 1 power switch with 1 AA electric battery, and LED lamp group is connected with other 1 power switch with other 1 AA electric battery.
2. according to the described laser sample prescription of claim 1 instrument, it is characterized in that: 4 red laser diode of laser diode group are placed along positive rectangular pyramid hypotenuse, and the height of this rectangular pyramid is half of the positive square length of side in bottom surface.
