Description

Soil erosion measuring device

The present invention relates to a soil erosion gauge, and more particularly to a soil erosion gauge that can be used for immediate observation of a particular area.

Soil erosion is a natural phenomenon, but human activities accelerate the process of soil erosion. The impact is land degradation and water ecological damage. Therefore, soil erosion is an important environmental problem. It is necessary to monitor soil erosion and Prevention and control, and the known soil erosion measurement is the measurement method of the catchment area of the catchment. The collected silt soil of the water collection area is collected, and the water of the soil is removed and weighed to quantify the phenomenon of soil loss.

However, according to the watershed export volume measurement method, the measured data lasted for a long time and covered the overall soil loss in the upstream area of a catchment area, and the immediate soil erosion phenomenon could not be observed, and it was impossible to observe the same. Several specific areas (such as different surface coverage or topography in the catchment area), and classify various forms of erosion and siltation.

Another conventional soil erosion measurement is the erosion pile (needle) method, which is nailed into the steel to be observed, and after the soil erosion occurs, the amount of erosion is estimated by measuring the bare length of the steel nail.

However, the use of erosion piles for soil erosion measurement, although the results of erosion and deposition at specific locations can be observed, but the instantaneous changes in soil erosion phenomena cannot be observed and recorded, and it is necessary to wait for a long time for a certain amount of sedimentation to be observed. And compare the pattern of soil erosion.

In view of this, the conventional soil erosion measurement does have the need to improve.

In order to solve the above problems, the present invention provides a soil erosion measuring device which is small in size and easy to disassemble, and can be disposed at an optional observation point to perform an immediate observation of the soil loss phenomenon in the region.

The soil erosion measuring device of the present invention comprises: a collecting container having a collecting box and a supporting portion, the earth collecting box having an opening and a first receiving space, the opening extending outward The sensing portion is disposed in the first receiving space of the earth-collecting box, the sensing group has a soil sensor and a weight meter or a pressure gauge for collecting soil related Data, a transmitter, the transmitter is disposed on the abutting portion, and is electrically connected to the sensing group, and transmits data measured by the sensing group; and a protective shell has a second The receiving space allows the collecting container and the sensing group to be placed in the second receiving space.

Accordingly, in the present invention, the soil erosion measuring device can be separately disposed in a plurality of soils to be measured to collect the soil lost by erosion, and then measure and immediately transmit the soil erosion amount and other Relevant data information, and the soil erosion measuring device of the invention has small volume, can be easily disassembled, is easy to carry and can be reused, and can improve the problem that the conventional soil erosion measurement is difficult to implement and cannot classify the erosion shape. The ability to perform immediate observations on multiple areas, and a smaller change in erosion amount can be observed compared to the erosion pile method.

Wherein, the earth-collecting box has a plurality of drainage pores formed on the box body and the bottom of the earth-collecting box, and penetrates the inner and outer wall surfaces of the earth-collecting box. In this way, it is possible to appropriately exclude the moisture accompanying the inflow of the soil, and to improve the collection capacity and the measurement accuracy.

The supporting portion is provided with two holding holes, and the two holding holes penetrate the upper and lower surfaces of the supporting portion, and the two holding holes preferably form an axial symmetry. In this way, the observation avoids affecting the trend of soil loss, and it is convenient to take out the collection container and reset after observation, and has the effects of improving measurement accuracy and being easy to install.

Wherein, the transmitter is located and protrudes from the upper surface of the abutting portion. In this way, when severe erosion causes a large amount of earth and stone to cover up the soil erosion measuring device, the transmitter can be less disturbed. The status sends a message, and there is also a marker location to assist in finding the location of the soil erosion gauge.

Wherein, the protective shell is a shell with a through hole, and the cross section of the second receiving space S2 is larger than the section of the earth collecting box. In this way, by burying the protective casing, the installation of the collecting container is simplified, and the earth collecting box is prevented from being directly pressed by the surrounding earth and stone, and has the functions of easy installation, protection and drainage passage.
