Description

Device for dividing and measuring pasture

Technical Field

The utility model belongs to the technical field of land survey measuring tool technique and specifically relates to a device for dividing and measuring pasture.

Background

With the division of new pastures in large area in China, the approval of the originally divided pastures and the continuous increase of the number of related ecological restoration projects, how to efficiently divide and measure the regional plots and the implementation of the implementation scheme become the difficulties of workers, and the division of the pastures is one of the specific implementation works. In the past, government staff need to verify the pasture boundary together with the herdsman, record the boundary division condition in a book, and determine the laying of fences according to the division area and the boundary.

There are many difficulties in the implementation process. Firstly, the staff needs to preliminarily determine a dividing boundary according to the positioning system, and then divide a plurality of coordinates on the formed boundary line to prompt fence laying, but the civil positioning system has an error of 3-5 meters in radius, which causes that the actually laid fence is not in a straight line, so that the measurement of the range of the pasture has larger deviation. If a boundary with a length of about 4 km is to be divided, a certain division deviation can be caused by a large deviation of determined coordinate points on the boundary, so that a herdsman is lost or a certain amount of pasture area is increased.

In the past, when a herdsman divides a boundary, a traditional method for determining a straight line by using two points exists. Firstly, red flags are inserted into the determined adjacent boundary points. An observer then stands under the red flag at one of the boundary points for handheld telescopic observation. The other person is used as an executor to hold the third red flag to approximately move between the two boundary points, and the executor is enabled to move to the middle of the two red flags by communicating with an observer through an interphone or a mobile phone. And finally, observing and directing the executor to finely adjust the position of the red flag by using a telescope until the executor inserts the red flag after the observer finds that three red flags are overlapped, so that a straight line is determined. Repeating the operation and the correction method to determine the positions of the multi-surface red flags on the boundary line, so that the boundary line is determined. The traditional method is relatively accurate in actual operation and is widely accepted by herdsmen, but has the following defects: (1) under the condition that the grassland color difference is basically similar or the pasture color is not obviously distinguished due to dark sky color, the visual identification of the red flag is influenced. In addition, if the observation visual angle of an observer is the same as the direction of the flag surface, the flag surface cannot be identified, so that the observation is blocked; (2) in complex terrains with hills or ditches, the traditional method cannot accurately measure due to the fact that the sight line is blocked.

To ensure accurate measurements, a laser rangefinder may be employed. Through inquiry, two main distance measuring instruments, namely a handheld laser distance measuring instrument and a telescope type laser distance measuring instrument, exist in the market. The handheld laser range finder is effective within a range of 250 meters, and errors are in millimeters, but the range finder cannot meet the requirements of herdsmen due to the fact that the range finder is too short. The effective range of the telescope type laser range finder can reach 5000 meters, but the error of the telescope type laser range finder increases along with the increase of the measured distance. In addition, the laser range finder is also influenced by weather, and a method and a matched device thereof for pasture environment are not needed. With the innovation of technology, the use of drones can also be used to determine distance. However, unmanned aerial vehicle ranging is similar to a positioning system in that it can only roughly determine the division of the boundary, and thus cannot accurately lay a standard fence boundary.

In view of the above problems, it is necessary to design a method that can adapt to the special environmental conditions of the pasture and can accurately divide the boundary of the pasture and be easily executed.

This application explains in detail from the embodiment of general case and two kinds of special cases (contain mound and highland), helps the user deepen to the understanding of the utility model to when facing different situations, can design one set of scheme that adapts to different situations.

Embodiment one

The general situation refers to that the measured overall topography of the pasture is flat, and no terrains such as hills, highland and valley exist, as shown in fig. 6. And observing a sketch drawn by earlier work, and finding that a graph formed by the surrounding of the measured boundary points is a trapezoid.

After the accurate division of the boundary and the fence laying datum line are solved on the sketch, workers only need to measure ∠ DAB, ∠ BCD, ∠ CDA and the shortest boundary line DC to calculate the distance of each boundary line and the area of the pasture.

In the following embodiment, boundary points A, B, C and D are known, and spud 2 is first installed at the B and D boundary points. Fixing of the fixing pile 2 needs to use a ring hammer 4, the ring hammer 4 needs to be sleeved into the fixing pile 2 from top to bottom, then the ring hammer fixing part 40 is vertically hammered until the fourth fixing cone 22 of the fixing pile 2 is completely inserted into the soil. Then, it is observed whether the vertical test unit 24 of the spud pile 2 shows a vertical state, which is not required to be adjusted to a vertical state. After the vertical adjustment is completed, the marker post 3 is taken out, the retractable shaft (i.e., the marker post body 30) of the marker post 3 is extended by the pulling portion 33 of the marker post 3, and the reflector 31 of the marker post 3 is attached to the second light source 34 of the marker post 3. Then, the marking rod 3 is sleeved into the fixing pile 2 from top to bottom, so that the marking rod is completely fixed on the ring-ramming fixing part 40 of the fixing pile body 20. After the operations are completed at the points B and D, at least one person is left at the points B and D as an observer, and devices and communication tools required by the measurement are left.

Thereafter, the solution starts from points a and C. First, the angle bracket 1 is placed at the boundary point of a and C, and the first fixed cone 103 is fixed in the soil before the second fixed cone 113 and the third fixed cone 123, so that the parent pile 10 can rotate freely, thereby facilitating the calibration. And then selects point a or point C to operate (the present solution is discussed beginning with point a). First, the observer at point a instructs the observer at points B and D to rotate the rotating part 35 of the marking rod 3 via the communication device, so that the reflector 31 of the marking rod 3 faces approximately to point a. At the same time, the first sub-pile 11 is rotated to point B, and the second sight 112 of the first sub-pile 11 and the first sight 102 of the parent pile 10 are aimed at the marking rod 3 mounted at point B, wherein the second sight 112 can adjust the height of the second sight 112 through the sight adjusting device 13, so that the first sight 102, the second sight 112 and the marking rod 3 of point B form three points and a line, and the boundary line AB is determined. This procedure is also used to rotate the second sub-pile 12 towards point D, with the slight difference that after aiming at point D, the angular rotation axis 105 of the parent pile 101 is fixed to prevent the second sub-pile 12 from wobbling. From this the borderline AD is determined. Similarly, the boundary lines CB and CD can be determined by the operation on the point C.

If the marker post 3 on the boundary lines of AD, AB, CB and CD is far and cannot be seen clearly by the observer, the first sight 102 can be replaced with a telescopic laser rangefinder, which has the same principle as the first sight 102 and is easy to measure remotely. Further, when the laser of the telescopic laser range finder strikes the reflector 31 of the marker post 3, the approximate distance value between the two target points can be seen in the display unit 16 on the parent pile body 101.

After the angle frame 1 is leveled, the angle of the horizontal included angle of the first sub pile 11, the mother pile 10 and the second sub pile 12 of the angle frame 1 is measured by an angle measuring unit, so that the angle of the horizontal included angle of the first sub pile 11, the mother pile 10 and the second sub pile 12 of the angle frame 1 is measured, the angle of the horizontal included angle of the DAB 26 and the BCD ∠ is measured, the angle of the CD83A is measured, meanwhile, a mark rod 3A and a mark rod C are sleeved on the mother pile 10, an observer can conveniently observe, pull the fixed pile, the angle of the fixed pile 1, the angle of the fixed pile 10, and the angle of the CDA 3A and the angle of the fixed pile 3A, the angle of the fixed pile 1, the angle of the fixed pile 10, and the angle of the first sub pile, the second sub pile 12 and the second sub pile 12.

And finally, accurately measuring the DC distance of the shortest side. The method is characterized in that the measurement of the shortest side determines the accuracy of the pasture area and all boundary lines, the specific operation method of the side for building the fence boundary prompt line is determined according to the actual situation, for example, factors such as terrain, distance and manpower situation are considered, and the operation is mainly realized by determining different intermediate point positions from the middle point of the DC side to two end points.

The specific operation steps are as follows, and the coordinates of the middle point on the DC edge can be roughly known through the previously drawn sketch. One person as the performer brings the required equipment to the approximate location of the DC midpoint E, finds the approximate direction, places it on the corner bracket 1 and rotates the second sub-pile 12 180 degrees and holds it in place so that the first sight 102, the second sight 112 and the third sight 122 form a straight line. Through known data and field observation, a first sight 102 is used for aiming at a point D, a second sight 112 is used for aiming at a point C, and positions are adjusted continuously, so that the first sight 102, the second sight 112, the third sight 122 and the point C of the corner bracket 1 of the point D and the middle point E form a straight line, and the accurate position of the DC middle point is determined according to the straight line.

Subsequently, the DC edge distance is specifically determined. The first sighting device 102, the second sighting device 112 and the third sighting device 122 of the angle frame 1 of the middle point E and the fourth sighting device 21 on the fixed pile 2 form three points and one line to respectively push and place the fixed pile 2 towards the directions of two boundary points, and then the fourth sighting device 21 of the three fixed piles 2 can form three points and one line to respectively shorten the distance to the end point towards the directions of the two boundary points and simultaneously place the fixed pile 2. It should be noted that the piles 2 are vertically fixed in the soil by the aid of the vertical test units 24 thereon, and the distance between the piles 2 may not exceed the accurate range (e.g., 250 m) of the laser ranging unit. The laser ranging unit is used to be simultaneously fixed with the fixing piles 2, after the distances between all the fixing piles 2 on the DC side and the distances between the fixing piles 2 and the angle frame 1 are measured, the extending length of the angle frame 1 and the thickness of the fixing piles 2 are combined, and the accumulated distance, the extending length of the angle frame 1 and the thickness of the fixing piles 2 are added to obtain the horizontal length of the DC side. Due to the flat topography of fig. 6, the laser ranging unit need only be mounted in the standard slot 51 of the angle bracket 1 and the spud 2, and the laser emitted therefrom must fall into the laser receiving tape 25 of the spud 2. However, when the distance measurement is performed in an uphill or downhill range within the measurement range, the laser distance measurement unit is correspondingly placed on the uphill notch 50 or the downhill notch 52 in order to prevent measurement errors caused by the height difference. After the distance data is measured, the laser ranging unit is pulled out, and the next fixing pile 2 is installed and placed in a reciprocating mode until the distance data is close to the terminal point.

According to the steps, the angle of the horizontal included angle of ∠ DAB, ∠ BCD and ∠ CDA and the horizontal length of the shortest boundary line DC are measured, after calculation, the distance of each boundary and the area of the pasture can be accurately obtained, meanwhile, the boundary line DC is also set as a datum line for building a boundary fence, and then, different numbers of marking rods 3 are set according to the condition in the visual range for the rest three sides according to the principle, but the marking rod at the middle point of each side needs to be set, and the three sides are set as fence boundary datum lines after the marking rods 3 are installed.

The determination of all boundary lines is completed in the above steps, but it is worth mentioning that the fourth sighting telescope 21 of the fixing pile 2 is made of a reflective material in consideration of the fact that the fixing pile 2 is not easy to find due to small grassland color difference. When sunshine is insufficient, mark pole 3 and spud pile 2 can not be observed to probably cause, so this scheme has increased first light source 23 at spud pile 2, and mark pole 3 has increased second light source 34, opens when the operation needs can. In addition, the second light source 34 of the marking rod 3 can also enhance the reflection of the reflector 31, so that the observation is easy, when the light source is insufficient, the color difference is increased due to the fact that the marking rod 3 and the fixing pile 2 carry light sources, and the measuring effect is better than that in the daytime.

It is noted that the laser ranging unit is positioned according to the situation of the pasture with uphill terrain and downhill terrain. If there is a valley in the area, it is shown in fig. 5, but since the valley does not obstruct the view, only a mark needs to be established outside the valley.

Embodiment three

The sketch drawn for the terrain shows that the graph defined by the boundary points is a trapezoid, a worker needs to make an auxiliary line BD in the implementation place, then measures ∠ CBA, ∠ CBD, ∠ CDB, the boundary lines CD and AC to calculate the distance of each boundary line and the area of the pasture, and then can determine ∠ BAD and ∠ ADC to determine the rotation angle of the A and D point angle frame 1, so that the fixing piles 2 can be arranged according to the AD direction and the DA direction, so far, the AD side which can not be measured through observation can be determined, and the function of constructing a boundary fence reference line is also played.
