Description

Technical Field

[0001] The present invention relates to the technical field of hydrological survey, and specifically to an intelligent survey buoy for measuring sediment content in water resources and a survey method thereof. Background Art

[0002] Hydrological surveys are used to evaluate and predict the possible interactions between various water conservancy facilities and the natural environment. When conducting hydrological surveys, samples are generally collected and analyzed using collection tools, and the condition of the water area is determined based on the analysis results.

[0003] Among them, the sediment content of water resources is an important survey data for hydrological surveys, and buoys are usually set up as sediment collection tools. When conducting water resource sediment content surveys, the buoys must be kept at the same water depth. The main reasons are as follows: the sediment sedimentation effect, because the sediment particles in the water body will naturally settle under the influence of gravity, resulting in the upper water body having a lower sediment content than the lower layer; the flow velocity stratification phenomenon, in natural waters, the flow velocity usually decreases with increasing depth (the surface flow velocity is the fastest, and the bottom layer is affected by friction resistance and is the slowest), and the water flow at different depths has different sediment carrying capacity (the faster the flow velocity, the greater the sediment transport capacity). If the buoy depth is unstable, that is, the sediment collection work is not carried out at the same water depth, the collected sediment samples will not represent the sediment content at the target depth. Therefore, maintaining the same depth is the core prerequisite for sediment content surveys. Its essence is to control vertical variables to ensure that the data only reflects the sediment dynamics of the target water layer. However, under the action of water flow, the buoy, as a tool for collecting sand in water resources, is prone to tilt. At the same time, as the sand is collected, the buoy will sink, resulting in the collection tool being unable to collect sand stably at the same depth in the water area, which in turn leads to the risk of inaccurate detection results.

[0004] The present invention requires the design of an intelligent survey buoy for measuring sediment content in water resources and a dynamic adjustment method thereof. Summary of the Invention

[0005] In view of the above shortcomings of the prior art, the purpose of the present invention is to provide an intelligent survey buoy for the sediment content of water resources and a survey method thereof. By adjusting the inclination angle of the buoy and the suspension height position in the water in real time, the stable collection of the sediment content in the water area at the same depth can be achieved, thereby solving the problem that the collection tool cannot collect sediment stably at the same depth in the water area, resulting in inaccurate detection results.

[0006] To achieve the above-mentioned and other related purposes, the present invention provides an intelligent survey buoy for measuring sediment content in water resources, comprising:

[0017] In one embodiment of the present invention, the floating body comprises:

[0018] A housing connected to the upper end of the body;

[0019] a micro air pump, the micro air pump being installed in the housing;

[0020] An airbag is arranged in the shell and is connected to the micro air pump.

[0021] In one embodiment of the present invention, the filter assembly further comprises a supporting frame, the supporting frame is fixedly mounted in the standard body, and the filter plate is fixedly mounted on the upper end of the supporting frame via the pressure sensor.

[0022] In one embodiment of the present invention, a water delivery port opposite to the water inlet is formed on the side wall of the water inlet chamber, and a valve is provided on the water delivery port.

[0023] In one embodiment of the present invention, two guide assemblies are further included, which are respectively installed on the outer sides of the upper and lower ends of the marker body. The guide assemblies are used to drive the marker body to rotate through the impact force of the water flow, so as to adjust the water inlet to align with the direction of the water flow.

[0024] In one embodiment of the present invention, each of the guide assemblies comprises:

[0025] A mounting ring, the mounting ring being sleeved on the standard body;

[0026] a pair of boxes, the boxes being symmetrically arranged on both sides of the mounting ring;

[0027] A plurality of guide plates are evenly distributed in each box.

[0028] In one embodiment of the present invention, a detection component is further included, and the detection component includes:

[0029] a distance sensor, the distance sensor being provided at the upper end of the float and being used to detect the height of the upper end of the float from the water surface;

[0030] An angle sensor is provided on the marker body and is used to detect the inclination angle of the marker body.

The buoyancy assembly and center of gravity adjustment assembly adjust the buoy's position, ensuring that the buoy remains stably suspended within the measured water area. This ensures accurate detection results for waters at the same depth. Furthermore, the present invention incorporates a comprehensive assessment model, employing multi-parameter coupling analysis and environmental compensation to ensure that the buoy remains in an optimal detection state, not just a "not exceeding the standard" state, even under complex hydrological conditions. The threshold provides a safety baseline, while model optimization enhances performance. The combination of these two prevents system runaway and improves detection accuracy.

DETAILED DESCRIPTION

[0047] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0048] It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0049] See also Figures 1 to 5 As shown, the present invention proposes an intelligent survey buoy for the sediment content of water resources, comprising a body 1, a filter assembly 2, a float 3, and a center of gravity adjustment assembly 5. The body 1 is a hollow tubular structure, and the tubular cavity is axially divided into one or more filter cavities; the float 3 is arranged at the upper end of the body 1 to provide adjustable buoyancy; the filter assembly 2 includes a filter plate 201 and a pressure sensor 202. The filter plate 201 is arranged in the filter cavity parallel to the cross section of the body 1 and divides the filter cavity into an inlet cavity and an outlet cavity. The pressure sensor 202 is arranged at the lower end of the filter plate 201; the center of gravity adjustment assembly 5 is connected to the body 1 to adjust the center of gravity of the body 1. Among them, the opposite side walls of the body 1 are respectively provided with a water inlet 101 connected to the water inlet cavity and a water outlet 102 connected to the water outlet cavity.

[0050] It can be understood that the filter plate 201 is used to filter the water resources entering the water inlet cavity of the standard body 1 through the water inlet 101, and the filtered water resources are discharged from the water outlet 102 of the water outlet cavity, and the pressure sensor 202 can detect the quality of the sand on the filter plate 201.

[0051] In one embodiment of the present invention, the tubular cavity of the standard body 1 further includes a mounting cavity, within which the center of gravity adjustment assembly 5 is disposed. The center of gravity adjustment assembly 5 includes a micromotor 501, a screw 502, and a counterweight 503. The micromotor 501 is mounted within the mounting cavity. The screw 502 is disposed axially along the standard body 1, with one end connected to the output shaft of the micromotor 501. The counterweight 503 is threadedly connected to the other end of the screw 502 and slidably engages the mounting cavity axially.

[0052] It can be understood that when the inclination sensor detects that the inclination angle of the mark body 1 is not within the preset inclination angle threshold, the micro motor 501 is started to drive the screw rod 502 to rotate. At this time, the screw rod 502 pushes the counterweight block 503 to move linearly along the axial direction in the installation cavity of the mark body 1 to change the center of gravity of the entire buoy, so that the inclination angle of the mark body 1 is within the preset inclination angle threshold range.

[0053] In one embodiment of the present invention, the float 3 includes a housing 301, a micro air pump 303, and an air bag 302. The housing 301 is connected to the upper end of the standard 1; the micro air pump 303 is installed in the housing 301; and the air bag 302 is arranged in the housing 301 and communicates with the micro air pump 303.

[0054] It can be understood that as the gas content in the airbag 302 increases or decreases, the buoyancy of the shell 301 can be relatively increased or decreased. When the distance sensor detects that the height of the upper end of the shell 301 from the water surface is not within the preset distance threshold range, the micro air pump 303 is started to pump air into the airbag 302, causing the entire buoy to float until the height of the upper end of the shell 301 from the water surface is within the preset distance threshold range.

[0055] In one embodiment of the present invention, the filter assembly 2 further includes a carrier 204 , which is fixedly mounted in the standard body 1 , and the filter plate 201 is fixedly mounted on the upper end of the carrier 204 through the pressure sensor 202 .

[0056] It is understood that the pressure sensor 202 can be fixedly connected to the upper end of the carrier 204, and the lower end of the filter plate 201 is fixedly connected to the pressure sensor 202. The water inlet 101 is set on the upper side of the filter plate 201, and the water outlet 102 is set on the lower side of the carrier 204.

[0057] In one embodiment of the present invention, a water delivery port is formed on the side wall of the water inlet chamber, opposite to the water inlet 101 , and a valve 203 is provided at the water delivery port.

[0058] It is understandable that the valve 203 can be embedded and installed through the installation groove. After the valve 203 is opened, the sediment on the filter plate 201 is forced to be discharged from the standard body 1 through the valve 203 under the impact of the water flow.

[0059] In one embodiment of the present invention, two guide assemblies 4 are further included, which are respectively installed on the outer sides of the upper and lower ends of the mark body 1. The guide assemblies 4 are used to drive the mark body 1 to rotate through the impact force of the water flow, so as to adjust the water inlet 101 to align with the direction of the water flow.

[0060] It can be understood that the guide plate 403 is used to steer the tube body 1. When the water inlet 101 is not facing the water flow, the water flow hits the side of the guide plate 403. At this time, under the action of the guide plate 403, the water flow drives the standard body 1 to rotate relative to the shell 301 until the water inlet 101 is facing the water flow. At this time, the water flow flows through the gaps between several adjacent guide plates 403, completing the steering of the standard body 1.

[0061] In one embodiment of the present invention, each guide assembly 4 includes a mounting ring 401, a pair of boxes 402, and a plurality of guide plates 403. The mounting ring 401 is mounted on the standard body 1; the pair of boxes 402 are symmetrically arranged on both sides of the mounting ring 401; and the guide plates 403 are evenly distributed in each box 402.

[0062] It should be noted that the guide plate 403 can be tilted 30° to 60° to ensure that the guide plate 403 can effectively decompose the impact force of the water flow into a rotational torque, that is, when there is an angle between the water flow direction and the water inlet 101, the impact on the tilted guide plate 403 generates a force arm.

[0063] It can be understood that the guide plate 403 is equivalent to a ship's rudder, and the setting of its inclination angle can ensure that the guide plate 403 can effectively decompose the impact force of the water flow into a rotational torque.

[0064] In one embodiment of the present invention, a detection component is further included, and the detection component includes a distance sensor and an angle sensor.

[0065] The distance sensor is arranged on the upper end of the float 3 to detect the height of the upper end of the float 3 from the water surface; the angle sensor is arranged on the mark body 1 to detect the inclination angle of the mark body 1.

[0066] Therefore, when the buoy of the present invention is in use, the relevant technicians place the buoy in the water area to be measured. At this time, under the guidance of the guide component 4, the water inlet 101 opened on the mark body 1 is facing the water flow direction, and the buoyancy component 3 causes the mark body 1 to float in the water. At this time, the filter plate 201 filters the water resources entering the pipe body 1 through the water inlet 101, and discharges the filtered water resources from the water outlet 102. The pressure sensor 202 can detect the quality of the sand on the filter plate 201. At the same time, the distance sensor and the distance sensor can detect the suspension depth position and inclination of the pipe body 1 in real time, and adjust the position of the mark body 1 through the buoyancy component 3 and the center of gravity adjustment component 5, so that the mark body 1 is stably suspended within the depth of the measured water area.

[0067] To achieve the above and other related purposes, the present invention proposes a method for intelligent surveying of water resources sediment content, using the above-mentioned intelligent surveying buoy for water resources sediment content, which specifically includes the following steps:

[0068] Step (1), buoy deployment: placing the buoy in the water area, and automatically aligning the water inlet 101 of the buoy body 1 with the water flow direction through the guide assembly 4, while the float 3 maintains the buoy body 1 in a suspended state;

[0069] Step (2), sediment filtration: water flows into the filter chamber of the standard body 1 through the water inlet 101, the filter plate 201 of the filter assembly 2 intercepts the sediment, the pressure sensor 202 detects the quality of the sediment in real time, and the filtered water is discharged from the water outlet 102 of the standard body 1;

[0070] Step (3), state adjustment: the distance sensor detects and obtains distance data in real time, and adjusts the buoyancy of the float 3 when the distance data exceeds a preset distance threshold;

[0071] The angle sensor detects the inclination data in real time, and when the inclination data exceeds a preset inclination threshold, the center of gravity of the standard body 1 is adjusted by the center of gravity adjustment component 5 .

[0072] Specifically, the distance sensor and the distance sensor can be used to detect the suspended depth position of the marker 1 (as the silt remaining on the filter plate 201 increases after filtering by the filter component 2, the weight of the entire buoy increases, causing the entire buoy to sink, and it is impossible to accurately measure the sediment content of water resources at the same depth) and the inclination in real time, obtain distance information and inclination information, and compare the obtained distance information and inclination information with the preset distance threshold and inclination threshold. If the distance information is not within the distance threshold range, the buoyancy of the buoyancy component 3 is adjusted to ensure that the distance information is within the distance threshold range. If the inclination information is not within the inclination threshold, the center of gravity adjustment component 5 is started to adjust the center of gravity of the entire buoy until the inclination information is within the inclination threshold.

[0073] Step (4), precision optimization:

[0074] Under the condition that the distance information and the inclination information are within the corresponding distance threshold and the inclination threshold, the distance data and the inclination data are dimensionlessly processed and input into the comprehensive evaluation model to calculate the evaluation coefficient. When the evaluation coefficient exceeds the preset coefficient threshold range, the state adjustment step is repeated until the evaluation coefficient is within the coefficient threshold.

[0075] The comprehensive evaluation model is expressed as:

[0076]

[0077] Among them, ZP(S, R) is the evaluation coefficient, S is the distance information, R is the inclination information, α is the distance information influencing factor, β is the inclination information influencing factor, W T is the influence factor of temperature on the distance sensor, W F is the influence factor of water pressure on the tilt sensor,

[0078] 0.53≤α≤1.2, 0.6≤β≤1, 0≤W T ≤1, 0≤W F ≤1.

[0079] It's understandable that the aforementioned precision optimization steps can improve sediment concentration detection accuracy at the same water depth. The role of the comprehensive assessment model is to go beyond simple threshold judgments. Through multi-parameter coupling analysis and environmental compensation, the buoy is consistently in the optimal detection state under complex hydrological conditions, not just in a "within-limit" state. This is the fundamental difference between intelligent monitoring equipment and traditional buoys. The threshold is the safety baseline, and model optimization improves performance. The combination of the two prevents system runaway and improves detection accuracy.
