Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping, in particular to a windproof surveying and mapping benchmark. Background Art

[0002] In surveying and mapping, environmental factors significantly impact measurement accuracy, with wind being a key factor. Traditional surveying poles have numerous shortcomings in terms of wind resistance. Their bases are simple in structure, with a small contact area with the ground and a lack of effective fixing methods, making them susceptible to imbalance in the wind. The pole bodies are typically not optimized for wind resistance, resulting in high wind resistance and susceptible to wind shock, causing them to shake or topple, impacting measurement accuracy and work continuity, and potentially accumulating errors that render data invalid. Furthermore, traditional poles have limited functionality, lacking features such as clear location markings and convenient calibration weights. Utility Model Content

[0027] Embodiment:

[0028] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0029] A windproof surveying benchmark, including a base 1, support columns 2 extending from four directions of the base 1, a spiked screw 3 provided at the distal end of the support column 2, a three-stage benchmark 4 installed above the base 1, a two-stage benchmark 5 installed above the three-stage benchmark 4, a one-stage benchmark 6 installed above the two-stage benchmark 5, a first position calibration strip 7 installed in front of the top of the base 1, a counterweight 8 that can be placed above the base 1, a spool 9 installed below the base 1, and the one-stage benchmark 6, two-stage benchmark 5, and three-stage benchmark 4 are all designed with hollow structures. A rope extends from the spool 9 and is connected to the top end inside the one-stage benchmark 6. The spiked screw 3 can be inserted into the soft ground by rotation, which further improves the stability of the equipment. The rope extending from the spool 9 is connected to the top end inside the one-stage benchmark 6, which improves the stability of the equipment itself from the inside.

[0030] Specifically, an indicator light 10 is installed above the one-stage benchmark 6. The indicator light 10 can play a reminder role to prevent people from forgetting the equipment.

[0031] Specifically, a second position calibration strip 11 is provided in front of the counterweight 8.

[0032] Specifically, the second position calibration strip 11 has scales and does not affect the measurement.

[0033] Specifically, when the counterweight 8 is installed, the first position calibration strip 7 is aligned with the second position calibration strip 11.

[0034] Specifically, the connection between the counterweight 8 and the base 1 is detachable. The counterweight 8 is directly placed above the base 1 and wraps the three-stage benchmark 4.

[0035] Specifically, an opening 12 is provided on one side of the counterweight 8. Its basic structure is similar to that of an old-fashioned mechanical counterweight.

[0036] Working principle:

[0037] Place the base 1 on the ground. According to the ground conditions, insert the spiked screw 3 at the distal end of the support column 2 into the soft ground by rotation, so that the base 1 is firmly fixed on the ground. Ensure that the support columns 2 in all four directions are firmly inserted into the ground to improve the overall stability.

[0038] Check whether the first position calibration strip 7 on the top of the base 1 is clearly visible and unobstructed.

[0039] Pull out the two-stage benchmark 5 from the three-stage benchmark 4 in sequence, and pull out the one-stage benchmark 6 from the two-stage benchmark 5. Note that the connection between the benchmarks should be tight to ensure the overall verticality and stability.

[0040] The rope drawn from the spool 9 below the base 1 is connected to the first-level benchmark 6. Ensure that the rope connection is firm and there is no looseness.

[0041] Place the counterweight 8 above the base 1 so that it wraps around the third-level benchmark 4. Pay attention to the direction of the opening 12 of the counterweight 8 for subsequent operations.

[0042] When installing the counterweight 8, ensure that the second position calibration bar 11 in front of the counterweight 8 is aligned with the first position calibration bar 7 on the top of the base 1. Through observing the scale on the second position calibration bar 11, perform precise calibration to make the position of the counterweight 8 accurate, so as to achieve the function of balancing and stabilizing the benchmark.

[0043] The number of counterweights 8 depends on the actual usage.

[0044] When conducting surveying work, surveyors can use surveying instruments such as levels and total stations to aim at the benchmark for measurement. The indicator light 10 above the first-level benchmark 6 can play a reminder role in a dim or complex environment, facilitating surveyors to quickly and accurately find the position of the benchmark.

[0045] During the measurement process, if there is a change in wind force, due to the hollow design of the benchmark and the functions of the rope and the counterweight 8, the influence of the wind on the benchmark can be effectively reduced, and the relative stability of the benchmark can be maintained. At the same time, the spiked screw 3 inserted into the ground also provides additional supporting force for the benchmark, further enhancing the stability under the action of wind force.

[0046] After the measurement work is completed, first remove the surveying instrument from the benchmark and place it properly.

[0047] Dismantle the counterweight 8, remove it from the base 1 and store it properly. Pay attention to avoiding collision and damage to the counterweight 8 and its components such as the second position calibration bar 11 and the opening 12 on it.

[0048] Dismantle the first-level benchmark 6, the second-level benchmark 5 and the third-level benchmark 4 in sequence, and store them together with the base 1 in an organized manner. At the same time, check whether the rope is wound neatly and whether the spool 9 is normal.

[0049] The above description is only the preferred embodiment of this application and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solution formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features with similar functions disclosed in this application.

[0050] Except for the technical features described in the specification, the remaining technical features are well-known to those skilled in the art. To highlight the innovative features of the present utility model, the remaining technical features will not be elaborated herein.
