Description

Technical Field

[0001] The present invention relates to the technical field of water resource surveying, and in particular to a portable hydrological and water resource surveying device and method. Background Art

[0002] With the continuous advancement of science and technology, significant progress has been made in sensor technology, data transmission technology, and materials science, providing technical support for the research and development of portable hydrological and water resources survey equipment. The emergence of new materials also helps to create lighter, sturdier and more corrosion-resistant survey equipment, improving the overall performance and adaptability of the equipment. In actual applications, the scenarios of hydrological and water resources surveys are becoming more and more diverse. In addition to traditional large-scale water body surveys of rivers and lakes, it also includes monitoring of small streams, urban rivers, farmland irrigation areas, and groundwater. In addition, in some emergency situations, portable survey equipment that can be quickly deployed is also needed to obtain relevant hydrological information in a timely manner to provide support for emergency decision-making. Therefore, in order to meet different scenarios and emergency needs, portable hydrological and water resources survey devices came into being.

[0003] Through water level surveys, we can understand the changes in the amount of water in rivers, lakes, and groundwater, and provide a basis for the rational development and utilization of water resources. For example, we can determine the water storage capacity of reservoirs and the runoff of rivers, so as to rationally plan irrigation and water supply distribution plans, monitor groundwater levels and water pressure, and promptly discover the problem of excessive groundwater exploitation. Excessive groundwater exploitation will cause the groundwater level to drop, triggering ecological and environmental problems such as ground subsidence, soil desertification, and vegetation degradation. Through water level and water pressure surveys, reasonable groundwater exploitation management measures can be taken to protect the groundwater ecological environment. In the existing technology, a pressure sensor is installed at the location where measurement is required. The sensor senses the water pressure and converts it into an electrical signal, which is transmitted to the measuring instrument through a cable for display and recording. However, the sensor is easily affected by water quality, temperature and corrosion, and requires regular calibration and maintenance. If the cable is not waterproof, water can easily enter during transmission, causing a short circuit. Summary of the Invention

[0016] A survey method based on a portable hydrological and water resources survey device specifically comprises the following steps: Step 1, start the telescopic rod, the telescopic rod will pull the fixed plate, so that the card column is pulled out from the inner wall of the card hole, then the line wheel is no longer restricted, and the weight of the sinking block will pull the measuring rope, causing the line wheel to rotate and loosen the measuring rope wrapped around the inner wall. When the sinking block goes deep into the water, the water will exert pressure on the pressure plate, causing the pressure plate to slide downward along the inner wall of the sinking block and squeeze out the internal air from the breathable plate, while water cannot pass through the breathable plate. By observing the position of the scale covered by the water surface, the depth of the water level can be judged, and by observing the distance the pressure plate has dropped, the size of the water pressure can be judged. Then the card column is inserted and the motor is started. The motor will drive the hollow shell and the line wheel to rotate together, and the measuring rope is retracted to the inside, so that the survey of water level and water pressure can be realized without being affected by external factors and without worrying about short circuit. Step 2, pull the rotating plate so that the rotating plate drives the rotating column 1 to slide outward along the inner wall of the support plate. After sliding to the bottom end, press the rotating plate so that the rotating plate rotates around the outer wall of the rotating column 1, and inserts the plug plate into the ground, and then rotate the top block. The top block will drive the threaded rod and the rotating column 2 to rotate. Since the outer wall of the threaded rod is threadedly connected to the inner wall of the fixed block 2, the threaded rod will push the rotating column 2 and the pointed head downward during the rotation process, so that the pointed head is inserted into the ground, which can achieve braking and fixing of the entire equipment to prevent it from tipping over due to unstable center of gravity when pulling up the sinking block.

[0017] The present invention has the following beneficial effects: 1. In the present invention, the telescopic rod is started, the fixed plate is pulled, the clamping column is pulled out from the clamping hole, the reel is released, and the weight of the sinking block drives the measuring rope to rotate the reel. The rope is loosened, and after the sinking block touches the bottom, the water pressure pushes the pressure plate to slide down, squeezing the air out from the breathable plate, and the water depth is read through the water surface scale. The distance the pressure plate descends reflects the water pressure. Finally, the clamping column is inserted, and the motor is started to retract the measuring rope. The water level and water pressure can be surveyed without being affected by external factors and without worrying about short circuits.

[0018] 2. In the present invention, the rotating plate is operated to make the rotating column 1 slide along the supporting plate to the bottom end, and then the rotating plate rotates around the rotating column 1 to insert the inserting plate into the ground. Then, the top block is rotated to drive the threaded rod and the rotating column 2 to rotate. The threaded rod is threadedly connected to the fixed block 2, pushing the rotating column 2 and the pointed head to move downward, so that the pointed head is inserted into the ground, thereby achieving braking and fixing of the entire device to prevent it from tipping over due to unstable center of gravity when the sinking block is pulled up.

This allows for convenient integration into various voltage comparator circuits and oscillator circuits. Each comparator within the LM339 has an independent non-inverting input ("+"), an inverting input ("-"), and an output.

Specifically, the clamping column 2051 is fixedly connected to the fixing plate 2042, ensuring the stability of the assembly. The clamping hole 2053 not only provides an additional fixing point for the reel 2052, but also increases its functionality. The measuring rope 2061 is fixedly connected to the reel 2052, ensuring the accuracy during measurement. The scale 2062 provides a clear reference for measurement, making the survey work more convenient and accurate. The bottom end of the measuring rope 2061 is fixedly connected to the sinking block 2063, so that the sinking block 2063 can perform pressure surveys more stably during underwater operations. The breathable plate 2065 can not only discharge the air in the sinking block 2063, but also prevent external moisture from entering the interior of the breathable plate 2065, thereby ensuring the efficiency and safety of the survey.

[0034] Working principle: When the telescopic rod 2041 is started, the telescopic rod 2041 will pull the fixed plate 2042, so that the clamping column 2051 is pulled out from the inner wall of the clamping hole 2053, and the line wheel 2052 is no longer restricted. The weight of the sinking block 2063 will pull the measuring rope 2061, causing the line wheel 2052 to rotate and loosen the measuring rope 2061 wrapped around the inner wall. When the sinking block 2063 penetrates into the bottom of the water, the water will exert pressure on the pressure plate 2064, causing the pressure plate 2064 to slide downward along the inner wall of the sinking block 2063 and remove the air inside.

A survey method based on the portable hydrological and water resources survey device according to any one of claims 1 to 9, characterized in that: The specific steps include: Step 1, start the telescopic rod (2041), the telescopic rod (2041) will pull the fixed plate (2042), so that the clamping column (2051) is pulled out from the inner wall of the clamping hole (2053), then the line wheel (2052) is no longer restricted, and the weight of the sinking block (2063) will pull the measuring rope (2061), so that the line wheel (2052) rotates and loosens the measuring rope (2061) wrapped around the inner wall. When the sinking block (2063) penetrates into the bottom of the water, the water will exert pressure on the pressure plate (2064), and the pressure plate (2064) will slide downward along the inner wall of the sinking block (2063), and the inner The air is squeezed out of the breathable plate (2065), while the water cannot pass through the breathable plate (2065). The depth of the water level is determined by observing the position of the scale (2062) covered by the water surface. The magnitude of the water pressure is determined by observing the distance the pressure plate (2064) descends. The clamping column (2051) is then inserted and the motor (2031) is started. The motor (2031) then drives the hollow shell (2032) and the reel (2052) to rotate together, and retracts the measuring rope (2061) into the interior.

Then rotate the top block (3063). The top block (3063) drives the threaded rod (3061) and the rotating column (3062) to rotate. Since the outer wall of the threaded rod (3061) is threadedly connected to the inner wall of the fixed block (304), the threaded rod (3061) pushes the rotating column (3062) and the pointed head (3064) to move downward together during the rotation process, so that the pointed head (3064) is inserted into the ground, thereby achieving braking and fixing of the entire device to prevent it from tipping over due to unstable center of gravity when the sinking block (2063) is pulled up.
