Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of observation devices, in particular to a rapid tide level observation device. Background Art
[0002] The current situation is: on the one hand, there is a lack of measurement equipment dedicated to tide warnings; on the other hand, the existing tide observation equipment is difficult to install when used on muddy coasts; thirdly, there is a lack of measurement equipment that is easy to use and has low or no maintenance.
[0003] Especially on muddy coasts where equipment installation conditions are harsh, tide level warnings can only be made through manual observations that are restricted by various conditions. Not only are the monitoring areas and frequencies limited, but in severe weather conditions where storm surges may occur, manual observations also have many unsafe factors.
[0004] Conventional tide observation equipment is usually divided into three categories:
[0005] (1) Float-type observation equipment. The use of this type of equipment first requires a large investment in infrastructure. In silted coastal areas, it is not easy to build the vertical shaft required for observation equipment, and dealing with the siltation of the vertical shaft will become a difficult task. This defect greatly limits the scope of use of traditional float-type tide level observation equipment;
[0006] (2) Pressure observation equipment. This is a relatively easy-to-install and easy-to-use device, but marine organisms and silt will clog the pressure sensor guide hole, which requires frequent cleaning, which is a major problem. Therefore, it is impossible to achieve continuous observation without maintenance for a long time, so its application scope is also greatly limited;
[0007] (3) Ultrasonic tide observation equipment. This is an underwater observation device. It has similar problems to float-type equipment in silted coastal areas. Each time the silt is dealt with, its elevation needs to be re-determined. However, determining the elevation of underwater equipment is not only cumbersome but also difficult.
[0008] The measurement accuracy of the above equipment is usually: 0.1% of the full scale, estimated at 10.0m, the accuracy is 1.0cm.
[0009] In summary, the above equipment has three obvious characteristics: first, the infrastructure is complex, the requirements are high, the investment is large, and the construction is difficult; second, it is difficult to determine the elevation; third, the environmental conditions for use are high, and frequent maintenance and supervision are required. In addition, the overall price is relatively high. Utility Model Content
[0010] 1. Technical problems to be solved by the utility model
[0011] The technical problem to be solved by the utility model is to provide a rapid tide level observation device, which solves the problems of high investment, difficulty in determining elevation and high requirements on environmental conditions.
[0012] 2. Technical solution
[0013] In order to solve the above problems, the technical solution provided by the utility model is:
[0014] A rapid tide level observation device comprises a shell, a counterweight rod is fixedly arranged at the bottom of the shell, pull rings are symmetrically arranged on both sides of the shell, and a GNSS module is fixedly arranged inside the shell.
[0015] Furthermore, a water level control line is provided on the housing at the upper side of the pull ring.
[0016] Furthermore, the bottom surface of the GNSS module is at the same height as the control water level line.
[0017] Furthermore, the counterweight rod is provided with a plurality of holes corresponding to the weight-increasing bolts.
[0018] Furthermore, the weight-increasing bolts can be selectively inserted into the holes corresponding to the weight-increasing bolts.
[0019] 3. Beneficial effects
[0020] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:
[0021] The technical solution provided by the utility model has no requirements for the location of the laying, does not require a large infrastructure investment, and is not afraid of marine organisms attaching and silt clogging the guide hole of the pressure sensor. It can be laid in huge winds and waves. Most of the existing tide observation equipment will be damaged in large winds and waves. In extreme cases such as typhoons, tide observation is very important for protecting people’s property safety. The device can also compare and verify the values of existing tide stations, and can perform tide testing for topographic measurements. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example
[0027] Combined with Figure 1-2 A rapid tide observation device includes a shell 10, a counterweight rod 12 is fixedly provided at the bottom of the shell 10, pull rings 13 are symmetrically provided on both sides of the shell 10, a GNSS module 11 is fixedly provided inside the shell 10, a control water level line 14 is provided on the shell 10 on the upper side of the pull ring 13, the bottom surface of the GNSS module 11 and the control water level line 14 are at the same height, and a plurality of weight-increasing bolt corresponding holes 15 are provided on the counterweight rod 12, and the weight-increasing bolt corresponding holes 15 can be selectively inserted with weight-increasing bolts 16.
[0028] The device is manufactured based on GNSS dynamic positioning. Since the salinity of each sea area is different, resulting in different buoyancy, the present application can change the overall draft of the device by inserting different numbers of weight-increasing bolts 16 into the corresponding holes 15 of the weight-increasing bolts, so that the part of the device above the control water level line floats to the surface.
[0029] The device as a whole has a heavy bottom and a light top structure. The outer shell 10 is a hollow structure, which is mainly used to provide buoyancy so that the device can partially float on the water surface. The counterweight rod 12 is a solid structure, which mainly plays a role in adjusting the balance between the device's own weight and the buoyancy of the device, so that the device can stably maintain the state of the part above the water level line floating on the water surface. After being affected by wind and waves, the left and right shaking will quickly restore the balance due to the gravity of the counterweight rod 12, and the average left and right shaking can be well averaged out when taking the average tide level.
[0030] In extreme weather conditions, such as tipping the device over, the bottom-heavy and top-light structure will automatically flip back quickly.
[0031] The GNSS module 11 dynamically locates and collects data within 5 minutes, takes the average value as the tide level at that moment, and continues to collect data within 5 minutes at intervals of 1 hour. This cycle is continued to recover the short-term tide level of the entire period of the device.
[0032] When in use, it is necessary to turn on the GNSS module in advance, then take the seawater in the measurement area, measure the salinity of the seawater, select the appropriate weight-increasing bolt 16 according to the salinity of the seawater and insert it into the corresponding hole 15 of the weight-increasing bolt. After the preparation is completed, the device can be thrown or deployed. There are two modes in the general implementation method. The first mode is to set up an emergency tide observation on the shore, connect the pull ring on one side of the device to the fixed position on the shore through a connecting rope, and then directly throw the device downward with a counterweight. The second mode is to deploy it through a ship, connect it to the device through a buoy, fix one end of the rope on the buoy, and fix the other end on the pull ring on the device, and then directly throw the device downward with a counterweight.
[0033] The principle of tide level collection is as follows:
[0034] The normal height of the phase center of the reference station (base station) and mobile station GPS antenna is:
[0035] H r m =h r +h ro H k m =h k +T (1)
[0036] When the distance between the reference station and the mobile station is not very far (the default is usually within 30 km), formula (2) and formula (3) are valid:
[0037] ξ=H r g -H k g -H k m (2)
[0038] H k m =H k g -ξ=H k g -H r g +h r +h ro (3)
[0039] So the tide value is:
[0040] T=H k m -H k (4)
[0041] Where: The antenna height of the reference station is h r , the antenna height of the mobile station GPS is h k (vertical distance from the GNSS antenna phase center to the control water level line);
[0042] The normal height of the known point is h ro ; The normal height and geodetic height at the reference station GNSS antenna are H r m , H r g ; The elevation anomaly is ξ; The normal height and geodetic height of the phase center of the mobile station GNSS antenna are H k m , H k g ; The instantaneous tide level obtained by GNSS observation is T.
[0043] GNSS tide gauge can directly obtain the instantaneous change of sea surface height. Although it overcomes the defects of traditional tide gauge methods, such as small scope or inability to conduct tide gauge in remote areas and the influence of tidal model errors, the instantaneous sea surface changes include long-period tidal level changes, medium- and long-period tidal waves and sea wave changes; the tidal level item is a long-period item, and the minimum period is greater than 1h; the surge effect is a short-wave item, with a period of 10 to 60s. In order to eliminate this influence, filtering and other methods are needed. There are many methods for tidal level extraction, such as the sliding average method, the Fourier transform method, and the threshold filtering method. The linear wave theory believes that the wave process is a weak stationary process with a zero mean. In the processing of ocean observation data, the "moving average" method is often used to decompose the data into wave signals and tidal and tidal signals. Although the sliding average method is the simplest filtering method, its processing effect is obvious, and it can also retain the physical process of tidal level changes to the maximum extent.
[0044] After completing the required data collection time, the device is directly recovered and the data is exported. Combined with the data collected by the reference station on the shore, the instantaneous tide level T observed by the device can be calculated.
[0045] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
