Description

Technical Field

[0001] The invention relates to the technical field of rainfall experiment observation auxiliary equipment, in particular to an auxiliary device for self-horizontal installation of a simple direct-reading rain gauge. Background Art

[0002] Using soil slopes with different slopes to conduct rainfall process experiments is an important means of studying hydrological processes. In the process of implementing rainfall experiments, it is necessary to install direct-reading rain gauges on slopes with different slopes of experimental soil to observe the rainfall process of the experiment, including observations and records of rainfall intensity, rainfall, and rainfall uniformity. Since the direct-reading rain gauge has a fixed shape, it is mainly suitable for conducting rainfall observations on horizontal sites. When the experimental conditions are carried out on soil slopes with different slopes, according to the measurement principle of the rain gauge, it is also necessary to ensure that the rain gauge is placed horizontally, but it is difficult to place the direct-reading rain gauge horizontally on the slope, and the soil often needs to be excavated to achieve the purpose; however, this method will cause disturbance to the experimental soil, causing the experimental data to deviate from the actual situation, thereby affecting the accuracy of measuring the rainfall process. Summary of the invention

[0003] In view of the above, it is necessary to provide a simple direct-reading rain gauge self-horizontally installed auxiliary device to solve the problem that the existing direct-reading rain gauge is difficult to be installed horizontally on slopes of different slopes.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] An auxiliary device for the self-leveling installation of a simple direct-reading rain gauge comprises a storage tube for storing the direct-reading rain gauge and a positioning steel chisel; the storage tube is cylindrical, comprising a base and a cylinder; the base comprises a seat body and a bubble level, the bubble level is installed in the seat body and arranged parallel to the bottom of the seat body; an annular groove is also arranged in the seat body, and the annular groove is arranged around the bubble level; an annular protrusion is arranged on the bottom surface of the cylinder body, and the annular protrusion is connected to the annular groove through cooperation; the cylinder body and the outer peripheral surface of the seat body are detachably connected through a tower buckle; the positioning steel chisel is vertically arranged on the bottom surface of the seat body.

[0006] Preferably, the auxiliary device further includes a plurality of reinforcement devices; the reinforcement device includes a reinforcement steel bar and a traction rope, one end of the traction rope is detachably connected to the top of the reinforcement steel bar, and the other end of the traction rope is detachably connected to the upper end of the positioning steel bar. In this way, the reinforcement steel bars of the plurality of reinforcement devices can be vertically inserted into the soil on the slope, and the positioning steel bar can be pulled from multiple directions by the traction rope, so that the positioning steel bar can be installed on the slope more stably, further improving the installation stability of the auxiliary device.

[0007] Preferably, the diameter of the reinforcement steel bar is 6-8 mm and the length is 200-300 mm. This arrangement makes the reinforcement steel bar of moderate length and relatively thin, so that it is easy to insert into the slope soil and less disturbs the slope soil.

[0008] Preferably, the storage cylinder further comprises a cylinder cover, which is movably covered on the top of the cylinder body and is provided with a matching hole for the direct-reading rain gauge to pass through, the diameter of the matching hole is the same as the outer diameter of the direct-reading rain gauge, and the material of the cylinder cover is soft rubber. In this way, the cylinder cover can effectively limit the movement of the direct-reading rain gauge in the cylinder body, making the installation of the direct-reading rain gauge more stable and protecting the direct-reading rain gauge; at the same time, the cylinder cover can also prevent rainwater from entering the cylinder body.

[0009] Preferably, the height of the cylinder is 100-200 mm, and the inner diameter of the cylinder is 2-10 mm larger than the outer diameter of the direct-reading rain gauge. This arrangement facilitates the cylinder to better accommodate the direct-reading rain gauge, and there is an appropriate space between the cylinder and the direct-reading rain gauge, so that the direct-reading rain gauge can be quickly installed in the cylinder or removed from the cylinder.

[0010] Preferably, the side wall thickness of the cylinder is 0.5-1.5 mm. This arrangement makes the cylinder lighter.

[0011] Preferably, the diameter of the positioning steel bar is 8-15 mm and the length is 300-500 mm. In this way, the diameter of the positioning steel bar is small and the length is long, so that the positioning steel bar can stably support the storage tube and the direct-reading rain gauge in the storage tube after being inserted into the slope soil, further ensuring the installation stability of the direct-reading rain gauge.

[0012] Preferably, the barrel, the seat, the positioning steel bar and the reinforcing steel bar are all made of stainless steel. This arrangement enables the auxiliary device to have a strong mechanical strength, which is conducive to extending the service life of the auxiliary device.

[0013] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0014] 1. The present invention is provided with a storage tube for storing a direct-reading rain gauge, and the storage tube can be flexibly installed on slopes with different slopes through a single positioning steel bar; after the positioning steel bar is inserted into the soil on the slope, the storage tube is adjusted to a horizontal position, and the direct-reading rain gauge is placed in the storage tube, so that the self-leveling installation of the direct-reading rain gauge can be completed; the positioning steel bar has a small diameter, and when inserted into the soil on the slope, the disturbance to the soil is small, and the slope of the experimental slope and the compactness of the soil will not be damaged, thereby ensuring the accuracy of the experimental results of the rainfall process, and it is also convenient for the experimenter to change different measurement positions according to the needs of the experiment during the experiment, which brings great convenience to the experimenter.

[0015] 2. The storage tube of the present invention comprises a base and a tube body, and the base and the tube body are in a detachable and separable form, so that the experimenter can more easily insert the positioning steel bar arranged at the bottom of the base into the slope soil; in addition, a bubble level is installed in the base to ensure that when the positioning steel bar is inserted into the slope soil, the experimenter can adjust the base to a standard horizontal position according to the bubble level, thereby effectively improving the accuracy of the horizontal installation of the direct-reading rain gauge.

[0016] 3. The present invention is also provided with a plurality of reinforcement devices, which can effectively improve the installation stability of the present invention on the slope; the reinforcement steel bar of the reinforcement device can be vertically inserted into the slope soil, and the positioning steel bar can be pulled from multiple directions by the traction rope, so that the positioning steel bar can be installed on the slope more stably.

[0017] 4. The present invention has the advantages of simple structure, easy use and low production cost, and solves two major problems encountered when the existing direct-reading rain gauge is installed on slopes of different slopes: (1) It is necessary to manually dig out a small plane for placing the direct-reading rain gauge, which is time-consuming and labor-intensive; (2) The manually dug small plane is easy to destroy the slope of the experimental slope and the compactness of the soil, resulting in low accuracy of the experimental data; the present invention has good practicality and is worthy of promotion.

[0026] Example

[0027] like Figure 1-3 As shown, a simple direct-reading rain gauge self-horizontal installation auxiliary device includes a storage tube 1 for storing a direct-reading rain gauge 15, a positioning steel bar 11 and a plurality of reinforcement devices 12. In this embodiment, the number of the reinforcement devices 12 is three.

[0028] The storage tube 1 is cylindrical and includes a base 2, a cylinder body 6 and a cylinder cover 9. The base 2 includes a base body 3 and a bubble level 4, which is installed in the base body 3 and arranged parallel to the bottom of the base body 3. An annular groove 5 is also arranged in the base body 3, and the annular groove 5 is arranged around the bubble level 4.

[0029] The bottom surface of the cylinder 6 is provided with an annular projection 7, and the annular groove 5 is connected with the annular projection 7. The cylinder 6 and the outer peripheral surface of the base 3 are detachably connected by a buckle 8. Among them, the cylinder 6 is a cylinder with an open upper end and a closed lower end. The height of the cylinder 6 is 100-200mm, and the inner diameter of the cylinder 6 is 2-10mm larger than the outer diameter of the direct-reading rain gauge 15, which is convenient for the cylinder 6 to better store the direct-reading rain gauge 15, and there is an appropriate space between the cylinder 6 and the direct-reading rain gauge 15, so that the direct-reading rain gauge 15 can be quickly installed in the cylinder 6 or removed from the cylinder 6. The side wall thickness of the cylinder 6 is 0.5-1.5mm, so that the weight of the cylinder 6 is relatively light. In this embodiment, the height of the cylinder 6 is 150 mm, the inner diameter of the cylinder 6 is 110 mm, the outer diameter of the direct-reading rain gauge 15 is 104 mm, and the inner diameter of the cylinder 6 is 6 mm larger than the outer diameter of the direct-reading rain gauge 15.

[0030] The cylinder cover 9 is movably covered on the top of the cylinder body 6, and is provided with a matching hole 10 for the direct-reading rain gauge 15 to pass through. The diameter of the matching hole 10 is the same as the outer diameter of the direct-reading rain gauge 15, and the cylinder cover 9 is made of soft rubber. The cylinder cover 9 can effectively limit the movement of the direct-reading rain gauge 15 in the cylinder body 6, making the installation of the direct-reading rain gauge 15 more stable and protecting the direct-reading rain gauge 15; at the same time, the cylinder cover 9 can also prevent rainwater from entering the cylinder body 6.

[0031] The positioning steel chisel 11 is vertically arranged on the bottom surface of the seat body 3 and is arranged perpendicular to the bottom surface of the seat body 3. The diameter of the positioning steel chisel 11 is 8-15 mm and the length is 300-500 mm. The positioning steel chisel 11 has a small diameter and a long length, so that the positioning steel chisel 11 can stably support the storage tube 1 and the direct-reading rain gauge 15 in the storage tube 1 after being inserted into the soil of the slope 16, further ensuring the installation stability of the direct-reading rain gauge 15. In this embodiment, the diameter of the positioning steel chisel 11 is 12 mm and the length is 400 mm.

[0032] The reinforcement device 12 includes a reinforcement steel bar 13 and a traction rope 14, one end of the traction rope 14 is detachably connected to the top of the reinforcement steel bar 13, and the other end of the traction rope 14 is detachably connected to the upper end of the positioning steel bar 11. The reinforcement steel bars 13 of the three reinforcement devices 12 can be vertically inserted into the soil of the slope 16, and the positioning steel bar 11 can be pulled from three directions by three traction ropes 14, so that the positioning steel bar 11 can be more stably installed on the slope 16, further improving the installation stability of the auxiliary device. Among them, the diameter of the reinforcement steel bar 13 is 6-8mm and the length is 200-300mm, so that the length of the reinforcement steel bar 13 is moderate and the reinforcement steel bar 13 is relatively thin, which is convenient for insertion into the soil of the slope 16 and causes less disturbance to the soil of the slope 16. In this embodiment, the diameter of the reinforcement steel bar 13 is 7mm and the length is 250mm.

[0033] In addition, the materials of the cylinder 6, the seat 3, the positioning steel chisel 11 and the reinforcing steel chisel 13 are all stainless steel, so that the entire auxiliary device has strong mechanical strength, which is conducive to extending the service life of the auxiliary device.

[0034] The steps of installing the direct-reading rain gauge 15 horizontally on the experimental slope 16 by the present invention are as follows: first, untie one end of the three traction ropes 14 to separate the traction ropes 14 from the reinforcement steel bar 13; then, open the tower buckle 8 on the storage tube 1 to separate the base 2 of the storage tube 1 from the cylinder body 6; then, insert the positioning steel bar 11 into the soil of the slope 16, and observe whether the base 2 is installed horizontally according to the bubble level 4. If the base 2 is not in a horizontal position, it needs to be adjusted to a horizontal position; then, select the appropriate position of the three reinforcement steel bar 13 and vertically insert it into the slope. The positioning steel bar 11 is pulled into the soil of the slope 16, and three traction ropes 14 are respectively tightened and tied to the top ends of the three reinforcement steel bar 13, so as to realize traction of the positioning steel bar 11 from three directions, so that the positioning steel bar 11 can be more stably installed on the slope 16; wherein, the angle between two adjacent directions is approximately 120°; then, the cylinder 6 is fitted onto the base 2 and fixed by the tower buckle 8; then, the cylinder cover 9 is removed from the cylinder 6, and the direct-reading rain gauge 15 is placed into the cylinder 6; finally, the cylinder cover 9 is passed through the direct-reading rain gauge 15, and covered on the top of the cylinder 6, and the installation is completed.

[0035] The present invention can be flexibly installed on slopes 16 of different slopes through a single positioning steel bar 11. The positioning steel bar 11 has a small diameter and is inserted into the soil of the slope 16, causing less disturbance to the soil and not damaging the slope of the experimental slope 16 and the compactness of the soil, thereby ensuring the accuracy of the experimental results of the rainfall process. It is also convenient for the experimenter to change different measurement positions according to the needs of the experiment during the experiment. The present invention also has the advantages of simple structure, convenient use and low manufacturing cost, and solves the two major problems encountered when the existing direct-reading rain gauge 15 is installed on slopes 16 of different slopes: (1) It is necessary to manually dig out a small plane for placing the direct-reading rain gauge 15, which is time-consuming and laborious; (2) The manually dug small plane is easy to damage the slope of the experimental slope 16 and the compactness of the soil, resulting in low accuracy of the experimental data; the present invention has good practicality and is worth promoting.
