Abstract

The utility model relates to a slope surface rill measuring device, and the device comprises vertical rods arranged on both sides and a transverse rod part transversely arranged between the vertical rods. The utility model is characterized in that a row of vertical through holes with the same spacing distance are densely arranged on the transverse rod part, a row of ranging rods with the identical length is correspondingly penetrated through the vertical through holes, and scale lines are also arranged on the vertical rods on the both sides. The utility model has the advantages that not only the structure is simple, the carrying is convenient, but also the manufacturing cost is low; the operation of two measuring methods provided by the utility model are very simple and convenient, and particularly the second measuring method can greatly improves the on site measuring speed, and facilitate the field measurement work.

Description

Domatic rill measurement mechanism

Technical field:

The utility model relates to and a kind ofly is used to measure because mountain region or the crop land soil erosion form the measurement mechanism of domatic rill.

Background technology:

According to statistics, slope arable land rill erosion accounts for the 60-80% of the erosion caused by sloping surfaces, measure the face of land at present because the rill that the soil erosion forms is to adopt (for example: the little face of land of laser scanner etc.) to measure than relatively large import instrument, though this instrument precision is higher, but it is bulky because of it, inconvenience is moved, need electric power etc., only be suitable for indoor simulated experiment and measure, and be difficult to be applicable to that open-air mountain region or crop land are because the measurement of the domatic rill that the soil erosion forms.So be badly in need of one simple in structure, portably use open-air easily domatic rill measurement mechanism.

Summary of the invention:

The purpose of this utility model is to provide a kind of mountain region in the open air or crop land generally to be used for measuring because the domatic rill measurement mechanism that the soil erosion forms, and this device is not only simple in structure, portably use convenience, and cost is low.

The utility model comprises the montant of being located at both sides and crosses at transverse bar between the montant, it is characterized in that: be densely covered with the equally spaced vertical through holes of a row on the described transverse bar, correspondence is equipped with the isometric mark post of a row in the described vertical through holes, also is provided with scale mark on the montant of described both sides.

The scale value of above-mentioned scale mark is laid on the surface of montant from top to bottom.

The length of above-mentioned mark post equals the distance to its bottom face of zero graduation value line position on the montant.

During measurement, the user places this device on the tested face of land, face of land rill is bigger than the mark post height of drop of depths, the mark post height of drop at the more shallow place of rill, the face of land is less, the depth of tested face of land rill just embodies at the upper extreme point of mark post, promptly, the pairing scale value of mark post upper extreme point is exactly the depth value of this rill, the gauger is a kind of to be to read and write down the pairing scale value of each mark post upper extreme point at the scene one by one, just finish the measurement of a measuring point, as measuring next measuring point, repeat above-mentioned flow process and get final product; Another kind is the gauger utilizes the pairing scale value of each mark post upper extreme point under the camera shooting in the dead ahead that is positioned at this device a image, and the measurement of a measuring point is promptly finished, and as measuring next face of land measuring point, repeats above-mentioned flow process and gets final product; After all on-the-spot face of land measuring points measure at last, will reflect the photograph image input computing machine of face of land rill form uniformly, and carry out data by computing machine and handle automatically.

The advantage of the utility model device is not only simple in structure, easy to carry, and low cost of manufacture.

Fig. 1 is the organigram of the utility model embodiment one;

Fig. 2 is the user mode synoptic diagram of the utility model embodiment one;

Fig. 3 is the organigram of the utility model embodiment two;

Fig. 4 is the user mode synoptic diagram of the utility model embodiment two;

Wherein 1 is montant, and 2 is transverse bar, and 3 is vertical through holes, and 4 is mark post, and 5 is scale value, and 6 is the indicating value plate, and 7 is the mark post line, and 8 is scale mark, and 9 are face of land depression.

Embodiment:

The utility model embodiment one comprises the montant 1 of being located at both sides and crosses at transverse bar 2 between the montant, it is characterized in that: be densely covered with the equally spaced vertical through holes 3 of a row on the described transverse bar 2, correspondence is equipped with the isometric mark post 4 of a row in the described vertical through holes 3, also is provided with scale mark 8 on the montant of described both sides.

The scale value 5 of above-mentioned scale mark 8 is laid on the surface of montant from top to bottom; The length of above-mentioned mark post equals the distance to its bottom face of zero graduation value line position on the montant, the scale value mark of starting from scratch from top to bottom, at this moment, the pairing scale value of mark post upper extreme point is the depth value of rill, the gauger can read and write down this numerical value easily, greatly facilitates measurement.

For mark post of the present utility model more being stablized and can being measured darker rill, the above-mentioned transverse bar 2 that crosses between the montant has two, and the height of transverse bar can upper and lower adjusting between the montant of both sides.

The utility model embodiment two is with the difference of embodiment one: the rear lateral portion that is positioned at the both sides montant is provided with an indicating value plate 6, described indicating value plate 6 is provided with and the scale value line of montant mark post line 7 one to one, be provided with the indicating value plate of mark post line, make the pairing scale value of mark post upper extreme point to come into plain view more, be convenient to more read and record.

A kind of using method of the utility model device, the gauger at first places this device on the face of land of measured point, the mark post that is placed through in the equidistant vertical through holes of a row falls into rill immediately, face of land rill is bigger than the mark post height of drop of depths, the mark post height of drop at the more shallow place of rill is less, the depth of face of land rill just embodies at the upper extreme point of mark post, the gauger can read and record one by one to the pairing scale value of each mark post upper extreme point, the measurement of a face of land measuring point is promptly finished, as measuring next face of land measuring point, repeat above-mentioned flow process and get final product.

The another kind of using method of the utility model device, the gauger at first places this device on the face of land of measured point, the mark post that is placed through in the equidistant vertical through holes of a row falls into rill immediately, face of land rill is bigger than the mark post height of drop of depths, the mark post height of drop at the more shallow place of rill, the face of land is less, the depth of face of land rill just embodies at the upper extreme point of mark post, the gauger utilizes the image of the pairing scale value of each mark post upper extreme point under the camera shooting in the dead ahead that is positioned at this device then, the measurement of a face of land measuring point is promptly finished, as measuring next face of land measuring point, repeat above-mentioned flow process and get final product; After all on-the-spot face of land measuring points measure at last, will reflect the photograph image input computing machine of face of land rill form uniformly, and carry out data by computing machine and handle automatically.

Remarkable advantage of the present utility model is: simple in structure, portably use conveniently, will more help the expansion that mountain region or crop land soil erosion cause Study on environmental pollution work.
