Description

Technical Field

[0001] The utility model relates to the technical field of soil and water conservation monitoring, in particular to a special measuring rod for soil and water conservation monitoring. Background Art

[0002] A simple soil erosion observation field is a facility that uses a set of measuring rods to measure the thickness of soil erosion on a slope. It is one of the most commonly used methods for monitoring soil loss in soil and water conservation monitoring work in construction projects. The measuring rods used are generally iron or steel rods with a length of 50cm to 100cm and a diameter of 0.5cm to 1cm, which are shaped like nails and are arranged at equal intervals in a grid pattern according to the slope area.

[0003] During the measurement process, the distance between the measuring rods is generally 1m to 3m, and the number is no less than 9. The measuring rods are driven into the slope along the plumb direction, and the original height between the top of the measuring rod and the ground is recorded. In some cases, due to the repeated use of the measuring rods, after a certain monitoring period (the monitoring period is generally 1 month, 3 months, etc.), the clarity of the scale on the rod body is insufficient, and it is necessary to place a ruler close to the side of the measuring rod. The monitoring personnel read the scale on the ruler to obtain the height of the measuring rod and the ground, and obtain the exposed length of the measuring rod by comparing the original height, and then calculate the amount of soil erosion, resulting in a large monitoring workload. In addition, the measuring rods lack identification, which can easily lead to confusion during the cross-cycle recording process. The above defects are problems that need to be urgently solved by those skilled in the art. In addition, it was found during the monitoring process that the measuring rod position is easily eroded by rainwater and pits appear, and large errors are likely to occur when measuring directly with a ruler close to the side of the measuring rod. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology, the utility model discloses a special measuring rod for soil and water conservation monitoring.

[0025] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be noted that the terms "upper" and "lower" etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of the present invention is usually placed when in use. These are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0027] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed connection, detachable connection, or integration; they may refer to direct connection or indirect connection through an intermediate medium; they may refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances. Example 1

[0028] Combined with attachment Figures 1 to 3A special measuring rod for soil and water conservation monitoring includes a drill rod 1, a scale sleeve 2 and a ring handle 3; the drill rod 1 is provided with a scale sleeve 2, and the scale sleeve 2 is provided with a scale ruler along its axis. There is no need to set a scale ruler on the drill rod 1. The scale can be observed through the scale sleeve, which is simple to operate. When the scale ruler on the scale sleeve 2 is worn or unrecognizable, it can be replaced, so that the drill rod 1 can be reused, effectively reducing the cost of use. A ring handle 3 is provided at one end of the drill rod 1. The ring handle 3 is provided with a number identification plate 4. When in use, a cordon can be inserted into the ring handle 3 to enclose a simple soil and water loss observation area with the cordon to increase recognition. The cordon can leave the monitoring personnel's phone number in case of emergency; the number identification plate 4 can be used to distinguish drill rods 1 in different positions, making it convenient for operators to record the corresponding exposed length of each drill rod 1.

[0029] The scale sleeve 2 can be made of stainless steel, and the processing technology is simple. Compared with replacing the entire measuring rod, it is cheaper to replace only the scale sleeve 2.

[0030] Furthermore, the numbering plate 4 is detachably connected to the ring handle 3 via a screw. When the number on the numbering plate 4 is worn, a new numbering plate 4 can be replaced. The numbering plate 4 can be numbered from 1 to 9 to distinguish the nine drill rods 1. If more than nine drill rods 1 are required, the numbering plate 4 can be replaced with 10 or more. The detachable connection can better meet the requirements of distinguishing different numbers of drill rods.

[0031] The end of the drill rod 1 away from the ring handle 3 is in a pointed cone structure, which can facilitate driving the drill rod 1 into the ground in the monitoring area.

[0032] In order to prevent the scale sleeve 2 from accidentally falling off during the detection process, the drill rod 1 is provided with a limiting structure to prevent the scale sleeve 2 from falling off;

[0033] As a preferred structure, Figure 2 As shown, the limiting structure is a screw that penetrates the wall of the scale sleeve 2 and is threadedly connected to the drill rod 1. Correspondingly, a screw hole matching the screw is provided on the rod body of the drill rod 1, that is, the scale sleeve 2 is fastened by the screw. When the scale sleeve 2 needs to be replaced, the screw can be removed to replace the scale sleeve 2.

[0034] As another preferred structure of the limiting structure, the limiting structure includes an elastic protrusion provided on the rod body of the drill rod 1, and a groove or bayonet matching the elastic protrusion is provided on the inner wall of the scale sleeve 2. That is, the elastic protrusion of the rod body of the drill rod 1 is connected with the groove on the inner wall of the scale sleeve 2 by corresponding engagement to achieve the purpose of positioning the scale sleeve 2. The elastic protrusion can be annular, such as Figure 3The structure shown can also be a column, similar to the clamping structure of an umbrella pole when it is extended. As for the elastic structure of the elastic protrusion, it can be similar to the elastic clamping column when the umbrella pole is extended. This is a prior art and will not be described in detail here.

[0035] It should be noted that if the elastic protrusion is annular and the limiting structure cooperates with the groove, the scale sleeve 2 can rotate along the axis of the drill rod 1, thereby making it convenient for the operator to rotate the scale sleeve 2 so that the reading of the scale is facing the operator's visual direction, making it convenient to read the reading of the scale.

[0036] It should be noted that if the monitoring point is difficult to reach, a camera can be used to take a photo and read the data of the scale sleeve 2 on the photo to obtain the exposed length of the drill rod 1.

[0037] In order to improve recognition or enhance the warning function, the scale sleeve 2 is provided with a warning pattern to improve its recognition. The warning pattern can be a red and white or yellow and white color pattern; the lengths of different color intervals are preferably set to the same length, so that even if taking a picture with a camera, the scale can be better identified. Example 2

[0038] In actual use, it was found that due to the lack of a reference object, it was still difficult to read the exposed length of the drill rod 1 when measuring it, and the connection position between the drill rod 1 and the ground was easily washed away by rainwater, resulting in pits along the drill rod 1, which easily led to large errors in measurement. In order to solve the above technical defects, this embodiment is further improved.

[0039] Combined with attachment Figure 1 、 4 5. A special measuring rod for soil and water conservation monitoring, which differs from the first embodiment in that an auxiliary bracket 5 is added on the basis of the first embodiment. The scale sleeve 2 is provided with an auxiliary bracket 5, which includes a small ring 5-1, a large ring 5-2 and a connecting rod 5-3. The small ring 5-1 is movably mounted on the outer periphery of the scale sleeve 2, and a large ring 5-2 is provided below. The small ring 5-1 and the large ring 5-2 are connected to each other by the connecting rod 5-3. The diameter of the large ring 5-2 is larger than the diameter of the small ring 5-1; that is, when measuring, the large ring 5-2 can be dropped to the ground, and the scale number at the position of the small ring 5-1 can be directly read. Since the small ring 5-1 is close to the scale of the scale sleeve 2 and the small ring 5-1 is fixed at a certain distance from the ground, reading is more convenient. In addition, the large ring 5-2 is larger than the diameter of the drill rod 1 and can be dropped directly to the ground outside the pit around the drill rod 1, thereby effectively reducing measurement errors.

[0040] In order to prevent the auxiliary bracket 5 from blocking the soil sliding down from above and forming a pit, the small ring 5-1 is hinged with clamping arms 5-4 on both sides, and the position where the clamping arms 5-4 are hinged to the small ring 5-1 is provided with a torsion spring for making one end of the clamping arm 5-4 contact with the body of the scale sleeve 2. More specifically, Figure 5 As shown, a hinge seat is provided on the bottom surface of the small ring 5-1, and a clamping arm 5-4 is provided on the outside of the small ring 5-1, with the middle portion protruding toward the side of the scale sleeve 2 and being hinged to the hinge seat by a pin. A torsion spring is installed at the pin, and the upper end of the clamping arm 5-4 protrudes toward the side of the scale sleeve 2 and presses against the outer wall of the tube body of the scale sleeve 2. That is, when the position of the auxiliary bracket 5 needs to be adjusted, the lower end of the clamping arm 5-4 is pressed so that the upper end of the clamping arm 5-4 is tilted and no longer presses against the outer wall of the tube body of the scale sleeve 2, thereby moving the position of the small ring 5-1 and the large ring 5-2. After the position adjustment is completed, the lower end of the clamping arm 5-4 is released, and under the action of the torsion spring, the upper end of the clamping arm 5-4 is reset to clamp the scale sleeve 2. Preferably, two clamping arms 5-4 are provided, located on both sides of the small ring 5-1. After each measurement, the auxiliary bracket 5 is raised and fixed to the body of the scale sleeve 2 by two clamping arms 5-4 so that the auxiliary bracket 5 is off the ground; when measurement is required, the auxiliary bracket 5 can be lowered to the ground by pressing the clamping arms 5-4.

[0041] A slot 6 is provided along the axis of the scale sleeve 2 at the position corresponding to the clamping arm 5-4. The two slots 6 are staggered with the scale on the body of the scale sleeve 2. The upper end of the clamping arm 5-4 is always clamped in the slot 6, which can avoid wear on the scale on the body of the scale sleeve 2.

[0042] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
