Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy monitoring equipment, and particularly to a hydrological survey instrument based on level information. Background Art

[0002] Water conservancy survey refers to work such as measurement, engineering geological exploration, underground water resource exploration, and irrigation area soil survey carried out for river regulation and water resource development, utilization, and protection. Its task is to investigate and study the nature, function, and internal laws of relevant natural phenomena in the planned river basin or area to be developed, evaluate and predict the possible mutual influences and various problems that may occur between various water conservancy facilities and the natural environment, and provide basic data and scientific basis for optimizing the planning, design, construction, and operation of water conservancy projects.

[0003] During the water conservancy survey process, it is essential to obtain and monitor water level information in real time, and avoid more serious disasters caused by too high water levels through early warning. The existing water level early warning is to observe the water level scale for early warning, which requires administrators to check it irregularly. During the flood season, administrators need to monitor the water level in real time to prevent vicious events caused by rising water levels, which is time-consuming and laborious and has low practicability.

[0004] According to the level information, that is, through the water level difference at different positions, the amount of tidal water is obtained to judge the bearing capacity of relevant facilities in coastal cities, so as to take timely measures to avoid disasters. The existing survey equipment mostly conducts single-point water level measurement, and cannot directly collect the water level change situation. Information processing is prone to deviation, resulting in misoperation and wasting human and material resources.

[0054] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0055] Embodiment 1

[0056] Please refer to Figures 1 to 7 , and now a specific implementation manner of a hydrographic survey instrument based on level information provided by the present invention will be described. This hydrographic survey instrument based on level information includes an upper measurement component 1, a lower measurement component 2, a potential difference acquisition component 3, and an early warning component 4. Among them, the upper measurement component 1 is used to measure the water level information at a position close to the observation area; the lower measurement component 2 is arranged on the side of the upper measurement component 1 away from the shore. One end of the upper measurement component 1 is fixed to the shore, and the other end extends into the water body. One end of the lower measurement component 2 extends out of the sea surface, and the other end extends into the sea and is fixed; the potential difference acquisition component 3 is connected to both the upper measurement component 1 and the lower measurement component 2 at the same time, and is used to acquire the change information of the water level difference between the positions where the upper measurement component 1 and the lower measurement component 2 are located; the early warning component 4 is arranged on the upper measurement component 1 and includes a primary early warning device 41 and an advanced early warning device 42. Both the primary early warning device 41 and the advanced early warning device 42 are electrically connected to the potential difference acquisition component 3.

[0057] For convenience of description, please refer to Figure 7, taking any point in space as the origin, the moving direction of the suspension member 14 as the Z-axis, the water flow direction as the Y-axis, and the direction of the straight line perpendicular to both the Y-axis and the Z-axis as the X-axis, a rectangular coordinate system is established. Among them, the XY plane is the horizontal plane, the direction indicated on the horizontal plane is the horizontal direction, the direction indicated by the Z-axis is the vertical direction, and as shown in the figure, the positive direction of the Z-axis indicates upward.

[0058] During operation, the potential difference acquisition component 3 uses the water level height obtained by the upper measurement component 1 as the level surface, and uses the level surface as the measurement standard for the lower measurement component 2 to obtain the elevation information of the lower measurement component 2, that is, the water level difference information between the positions of the upper measurement component 1 and the lower measurement component 2. At the same time, reasonable maximum water level difference information, primary warning water level value, secondary warning water level value, and secondary warning water level value are set according to the geographical environment information and water flow conditions. Case 1: If the water level difference is within the specified maximum value range and the water level of the upper measurement component 1 is higher than the primary warning line, it means that the overall water potential has risen to a relatively high level, and it is easy to generate danger and requires warning and corresponding protective measures. At this time, the high-level warning device 42 lights up and issues an alarm message. Case 2: If the water level difference exceeds the specified maximum value and the water level of the upper measurement component 1 is higher than the primary warning line, it means that the water flow suddenly increases in the first stage but does not cause the overall water level to rise, and the danger is relatively small. It is necessary to judge whether to take protective measures according to the subsequent water level changes. At this time, the primary warning device 41 lights up. Case 3: If the water level difference exceeds the specified maximum value and the water level of the upper measurement component 1 is higher than the secondary warning line, it means that the observed flow rate and water level increase are too large, and it is easy to generate danger and requires warning and corresponding protective measures. At this time, the high-level warning device 42 lights up and issues an alarm message. Case 4: If the water level difference exceeds the specified maximum value, the water level of the upper measurement component 1 is higher than the primary warning line, and at the same time the water level of the lower measurement component 2 is higher than the secondary water level line, it means that although the water level difference is large, it is in the stage of overall water level rise, and it is easy to generate danger and requires warning and corresponding protective measures. At this time, the high-level warning device 42 lights up and issues an alarm message. Here, as long as the relevant performance functions of the above-mentioned primary warning device 41 and high-level warning device 42 can be realized, they are within the scope of protection of this application document.

[0059] Compared with the prior art, through the cooperation of the potential difference acquisition component 3 and the warning component 4, this kind of hydrological survey instrument based on level information can judge whether the water level will exceed the dangerous range according to the water level difference information within a certain distance. The water levels of the upper measurement component 1 and the lower measurement component 2 form a reference for each other, avoiding obtaining wrong information without reference when the water level suddenly rises at one position, resulting in losses of human and material resources. The water level information monitored by the present invention is more accurate, and there is no need for manual supervision at all times. The water level situation can be remotely observed through the warning component 4, which is convenient to use and greatly saves human resources. The present invention solves the problems existing in the prior art, such as cumbersome supervision, time-consuming and laborious, and poor practicability; it cannot intuitively monitor the change of the water level, and there are easy deviations in information processing, resulting in misoperations and wasting human and material resources. The structure is simple, the effect is remarkable, and it is suitable for wide promotion.
