Description

Technical Field

[0001] The present invention belongs to the technical field of wave measurement, and particularly relates to a radar wave direction, wave height and wave period measuring instrument with a fixed installation. Background Art

[0002] With the rapid development of the marine economy, human maritime activities are increasing day by day. Natural disasters such as typhoons and storm surges have a significant impact on the pace of ocean development and utilization. The occurrence of natural disasters such as typhoons and storm surges is bound to cause changes in marine observation elements. It is necessary to carry out forecasting, prevention, disaster prevention and mitigation of natural disasters by observing marine observation elements. Among many marine observation elements, waves are the most important and complex one, and are also one of the important contents of physical oceanography research. They are important input parameters in the fields of ocean forecasting, ocean engineering, disaster prevention and mitigation, maintenance of maritime rights and interests, and navigation safety.

[0003] Ocean waves contain huge energy. They can make ships sway or even cause shipwreck accidents. They are extremely harmful to offshore operations and have great destructive effects on coastal protection, port terminals, etc. The research and application of using radar wave measuring instruments to conduct ocean wave measurement can effectively monitor wave information at sea and conduct sea condition forecasting, which is conducive to improving the disaster prevention ability of ports, helping to reduce the losses of coastal ports under extreme disaster conditions, and providing guarantee for the safety of coastal port and terminal production operations and people's lives and property, and has very important significance.

[0004] The Korean invention patent with the application number KR1020230031032A discloses a wave measuring buoy with a solar cell. The wave measuring buoy includes: a floating body that floats on the water surface by buoyancy; a controller that is connected to the floating body to measure the wave height of the water surface where the floating body floats and control the generation of electric energy; and a buffer part that is installed on the floating body to disperse or absorb the impact applied to the floating body from the outside, so that it can be stably positioned on the water surface to accurately measure the wave height, and accurately locate the ships in navigation by increasing the radar reflection area. This type of wave measuring device in the prior art is applicable to sea surface buoys, and the wave measuring radar is fixedly arranged, and a predetermined array setting needs to be carried out before launching. When this type of device is applied to a base station on the shore, the detection range cannot be adjusted, which has limitations. Summary of the Invention

[0005] The purpose of the present invention is to provide a radar wave direction, wave height and wave period measuring instrument with a fixed installation, which has a simple structure, high adaptability to the sea surface environment and accurate wave measurement.

[0006] The technical solution adopted by the present invention to achieve the above purpose is as follows:

[0007] A fixed-mounted radar wave direction, wave height, and wave period measuring instrument, comprising: a radar probe and a shore-based fixed bracket. The shore-based fixed bracket includes a moving mechanism, and the moving mechanism includes a moving platform and a traction connecting rod. Moving guide rails are evenly arranged above the moving platform, and any one of the moving guide rails is movably connected to the radar probe. The moving guide rails and the traction connecting rod cooperate to enable the radar probe to switch between a point array and a triangular array. When the radar probe forms a point array, the three radar probes are close to each other. One of the radar probes has a vertically downward detection direction, and at least two of the other radar probes are inclinedly installed to form a triangular radar reflection area, which is suitable for the measuring instrument to be arranged near the sea surface. However, since the radar probes of the point array are inclinedly installed, a large number of clutter signals formed by internal reflections will be generated due to the large incident angle of the radar reflection area;

[0008] When the radar probe forms a triangular array, the three radar probes are arranged in a triangle, and the radar probe directly irradiates vertically downward, which is suitable for the measuring instrument to be arranged when it is far from the sea surface. The triangular array can obtain a standard radar reflection area close to an equilateral triangle, which is convenient for calculating various wave characteristic elements such as wave direction, wave height, and wave period in the radar reflection area;

[0009] The present invention can switch between a point array and a triangular array, and can be applicable to different height differences between the present invention and the sea surface. Under both stable sea conditions when the sea surface is low and severe sea conditions when the sea surface is high, the current wave direction, wave height, wave period and other wave characteristic elements can be obtained, improving the timeliness and accuracy of natural disaster reporting under complex sea conditions. At the same time, since the present invention can switch to a point array mode under severe sea conditions, it can reduce the volume of the present invention and increase the structural strength of the present invention, thereby improving the service life.

[0010] Preferably, the extension lines of each moving guide rail intersect at the center of the upper end surface of the moving platform. The radar probe can move within the moving guide rail connected to it, and the detection direction of the radar probe is arranged downward, and the radar probe is located below the moving platform. The moving guide rails are arranged on the upper end surface of the moving platform, avoiding height differences between the radar probes. At the same time, it is convenient for the coordinate calibration mechanism to indirectly uniformly calibrate the position coordinates of all radar probes by calibrating the moving platform, avoiding affecting the measurement results of the measuring instrument; the extension lines of the moving guide rails intersect at the center of the upper end surface of the moving platform, that is, the moving guide rails are evenly angularly spaced around the intersecting common intersection point, which is convenient for the radar probe to always be located at the vertices of the same equilateral triangle during the movement to form a standard radar reflection area, avoiding the need to adjust the information processing algorithm of the measuring instrument according to the actual radar reflection area before use, and reducing the installation and use threshold and installation and use cost of the measuring instrument.

[0011] Preferably, the shore-based fixed bracket further includes a fixed main shaft. Each moving guide rail is movably connected to a corresponding traction connecting rod. One end of the traction connecting rod is connected to the radar probe, and the other end of the traction connecting rod is connected to the fixed main shaft. By using the cooperation of the fixed main shaft and the traction connecting rod, during the movement of the radar probe, the vertices of the triangle of the radar reflection area are displaced relative to the center of the triangle, which is convenient for the measuring instrument to reset the relevant parameters of the radar reflection area after the radar probe moves, and is convenient for calculating various wave characteristic elements such as wave direction, wave height, and wave period.

[0012] Preferably, a connecting head is provided at the top of the radar probe. The connecting head has an ear hole that is rotatably connected to the moving mechanism, and the curvature of the inner contour of the ear hole is not a fixed value. By using an ear hole with a changing inner contour curvature, during the movement of the traction connecting rod, the pitching angle of the radar probe will change. Further, when the traction connecting rod pulls the radar probe inward, that is, when the radar probe approaches the fixed main shaft, the detection direction of the radar probe turns outwards, realizing the switching of the radar probe of the measuring instrument between the point array and the triangular array. Since the radar probes approach each other when the array changes, the area of the detection area formed by them shrinks. The above technical solution can make the radar probes approach each other while tilting and turning away from each other, thereby expanding the reduced detection area, that is, by reducing the overlap degree of the detection areas of the radar probes, expanding the detection range, overcoming the problem of the reduction of the detection area caused by the array change in the prior art, ensuring a stable detection area formed by the radar probes, and thus improving the detection stability of the sea surface wavelength in different array modes;

[0013] The radar probe tilts outwards through the above solution, so that the radar probes are relatively concentrated at the center below the moving platform. On the one hand, it converges the overall center of gravity of the device, improves the hanging stability of the radar probe at the installation location, reduces the frequency of strong jitter of the overall device affected by strong airflows, reduces the connection interference of the traction connecting rod, and improves the detection stability of the radar probe for wave height and wavelength, ensuring that the radar probe detects data such as wave height and wavelength at the preset height, and improving the measurement accuracy and authenticity;

[0014] Since the device is fixedly installed, when it encounters bad weather such as heavy rain and heavy snow at sea, the radar probe is retracted to the middle below the moving platform through the traction connecting rod, and the moving platform forms an upper shield for the radar probe, reducing the possibility of damage to the radar probe and reducing the maintenance cost.

[0015] Preferably, the traction connecting rod includes an active rod and a driven rod. An angle can be formed between the active rod and the driven rod that is close to the moving platform, and the angle is always less than a flat angle. The driven rod is provided with a driving end connected to the radar probe, and the active rod is provided with a connecting end movably connected to the fixed main shaft.

[0016] Preferably, a slideway is provided on the surface of the fixed main shaft. While the connecting end can slide within the slideway of the fixed main shaft, it can also rotate. The driving end passes through the moving guide rail and is rotatably connected to the radar probe. Since the included angle between the active rod and the driven rod is less than 180°, in combination with the connector at the top of the radar probe, when the radar probe is far from the fixed main shaft, the detection direction of the radar probe is vertically downward; when the radar probe is close to the fixed main shaft, the detection direction of the radar probe turns outward.

[0017] Preferably, the fixed main shaft is connected to the center of the upper end of the moving platform, and a coordinate calibration mechanism is provided at the connection between the fixed main shaft and the moving platform. By setting a coordinate calibration mechanism between the fixed main shaft and the moving platform, it is beneficial for the measuring instrument to perform mechanical calibration after installation, ensuring that the moving platform is horizontal and the fixed main shaft is perpendicular to the moving platform, enabling the radar probe to form a standard radar reflection area, facilitating the installation and use of the measuring instrument and the establishment of calculation coordinates by the measuring instrument; after the measuring instrument is affected by long-term sea wave impacts, bad weather, or even natural disasters, the measuring instrument or the installation platform of the measuring instrument tilts. By performing mechanical calibration on the measuring instrument, the measuring instrument can be put back into use, reducing the use cost of the measuring instrument.

[0018] Preferably, the coordinate calibration mechanism is used to adjust the relative attitude between the fixed main shaft and the moving platform.

[0019] Preferably, the fixed main shaft is laterally provided with an extended support rod on the side, and the extended support rod is used to provide a lateral layout space for the radar probe and the shore-based fixed bracket.

[0020] Preferably, the shore-based fixed bracket further includes a housing. The housing is conical with the small end facing upward. The bottom end of the housing is installed on the upper end of the moving platform, and both the moving guide rail and the traction connecting rod are located inside the housing. The conical housing forms an external protection for the moving guide rail and the traction connecting rod, reducing the erosion of salt spray that may cause the radar probe to be unable to change its array. The outer wall of the conical housing is conducive to guiding the lateral air flow, reducing the influence of strong lateral air flow on the microwave transmission of the radar probe, and thus improving the accuracy of wave measurement;

[0021] Since the radar probe needs to be connected to a power source through a cable to form continuous power supply, the housing shields the cable connection, reducing the possibility of poor contact of the cable under the influence of salt spray, thereby stabilizing the radar probe to emit microwaves at an accurate cycle to detect wave information.

[0022] Due to the adoption of an adjustable shore-based fixed bracket, the present invention has the following beneficial technical effects: The radar probe carried by the present invention can be switched between different modes in the long term and short term, adapting to different installation conditions and changes in ocean conditions, and has the following beneficial effects. By using a coordinate calibration mechanism, the mobile platform is ensured to be horizontal and the fixed main shaft is perpendicular to the mobile platform, enabling the radar probe to form a standard radar reflection area, facilitating the installation and use of the measuring instrument and the establishment of calculation coordinates by the measuring instrument; after the measuring instrument is affected by long-period sea waves, bad weather or even natural disasters, the measuring instrument or the installation platform of the measuring instrument tilts, and mechanical calibration is performed on the measuring instrument, enabling the measuring instrument to be put back into use and reducing the use cost of the measuring instrument; when a natural disaster is approaching, switching to a point array mode can reduce the volume of the present invention and increase the structural strength of the present invention, thereby extending the service life.

DETAILED DESCRIPTION OF THE INVENTION

[0032] The technical solutions of the present invention will be further described in detail below in conjunction with the specific embodiments and the drawings:

[0033] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] A fixed-mounted radar wave direction, wave height and wave period measuring instrument includes: a radar probe 1 and a shore-based fixed bracket. The shore-based fixed bracket includes a moving mechanism. The moving mechanism includes a moving platform 3 and a traction connecting rod 6. Moving guide rails 4 are evenly arranged above the moving platform 3. Any one of the moving guide rails 4 is movably connected to the radar probe 1. The moving guide rails 4 cooperate with the traction connecting rod 6 to enable the radar probe 1 to switch between a point array and a triangular array. When the radar probe 1 forms a point array, the three radar probes 1 are close to each other. One of the radar probes 1 has a detection direction vertically downward, and at least two of the other radar probes 1 are inclinedly installed to form a triangular radar reflection area, which is suitable for the measuring instrument to be arranged near the sea surface. However, since the radar probes 1 in the point array are inclinedly installed, a large number of clutter signals formed by internal reflections will be generated due to the large incident angle in the radar reflection area.

[0035] When the radar probe 1 forms a triangular array, the three radar probes 1 are arranged in a triangle, and the radar probe 1 directly irradiates vertically downward, which is suitable for the measuring instrument to be arranged when it is far from the sea surface. The triangular array can obtain a standard radar reflection area close to an equilateral triangle, which is convenient for calculating various wave characteristic elements such as wave direction, wave height, and wave period in the radar reflection area.

[0036] The present invention can switch between a point array and a triangular array, and can be applicable to different height differences between the present invention and the sea surface. Under stable sea conditions when the sea surface is low and under severe sea conditions when the sea surface is high, the present invention can obtain various wave characteristic elements such as current wave direction, wave height, and wave period, improving the timeliness and accuracy of natural disaster reports under complex sea conditions. At the same time, since the present invention can switch to the point array mode under severe sea conditions, it can reduce the volume of the present invention and increase the structural strength of the present invention, thereby improving the service life.

[0037] The extension lines of each moving guide rail 4 intersect at the center of the upper end face of the moving platform 3. The radar probe 1 can move within the moving guide rail 4 connected thereto. The detection direction of the radar probe 1 is arranged downward, and the radar probe 1 is located below the moving platform 3. The moving guide rails 4 are arranged on the upper end face of the moving platform 3 to avoid height differences between the radar probes 1. At the same time, it is convenient for the coordinate calibration mechanism 7 to indirectly calibrate the position coordinates of all the radar probes 1 uniformly by calibrating the moving platform 3, so as not to affect the measurement results of the measuring instrument; the extension lines of the moving guide rails 4 intersect at the center of the upper end face of the moving platform 3, that is, the moving guide rails 4 are evenly distributed at angular intervals around the intersecting common intersection point, which is convenient for the radar probes 1 to always be located at the vertices of the same equilateral triangle during the movement process to form a standard radar reflection area, avoiding the need to adjust the information processing algorithm of the measuring instrument according to the actual radar reflection area before use, and reducing the installation and use threshold and installation and use cost of the measuring instrument.

[0038] The shore-based fixed bracket further includes a fixed main shaft 5. Each moving guide rail 4 is movably connected with a corresponding traction connecting rod 6. One end of the traction connecting rod 6 is connected to the radar probe 1, and the other end of the traction connecting rod 6 is connected to the fixed main shaft 5. By using the cooperation of the fixed main shaft 5 and the traction connecting rod 6, during the movement process of the radar probe 1, the vertices of the triangle of the radar reflection area are displaced relative to the center of the triangle, which is convenient for the measuring instrument to reset the relevant parameters of the radar reflection area after the movement of the radar probe 1, and is convenient for calculating various wave characteristic elements such as wave direction, wave height, and wave period.

[0039] A connecting head is provided at the top of the radar probe 1. The connecting head has an ear hole rotatably connected to the moving mechanism, and the inner contour curvature of the ear hole is not a fixed value. By using an ear hole with a changing inner contour curvature, during the movement of the traction connecting rod 6, the pitching angle of the radar probe 1 will change. Further, when the traction connecting rod 6 pulls the radar probe 1 inward, that is, when the radar probe 1 approaches the fixed main shaft 5, the detection direction of the radar probe 1 turns outwards, realizing the switching of the radar probe 1 of the measuring instrument between the point array and the triangle array. Since the radar probes 1 approach each other during the array change, the area of the detection area formed by them shrinks. The above technical solution can enable the radar probes 1 to approach each other while tilting and turning away from each other, so as to expand the reduced detection area, that is, by reducing the overlap degree of the detection areas of the radar probes 1, the detection range is expanded, overcoming the problem of the reduction of the detection area caused by the array change in the prior art, ensuring a stable detection area formed by the radar probes 1, and thus improving the detection stability of the sea surface wavelength in different array modes;

[0040] The radar probe 1 is tilted outwards through the above solution, so that the radar probe 1 is relatively concentrated at the center below the mobile platform 3. On the one hand, the overall center of gravity of the device is converged, the hanging stability of the radar probe 1 at the installation location is improved, the frequency of strong jitter of the overall device affected by strong air flow is reduced, the connection interference of the traction link 6 is reduced, and the detection stability of the radar probe 1 for wave height and wavelength is improved, ensuring that the radar probe 1 detects data such as wave height and wavelength at a preset height, and improving the measurement accuracy and authenticity;

[0041] Since the device is fixedly installed, when it encounters bad weather such as heavy rain and heavy snow at sea, the radar probe 1 is converged in the middle below the mobile platform 3 through the traction link 6, and the mobile platform 3 forms an upper shield for the radar probe 1, reducing the possibility of damage to the radar probe 1 and reducing the maintenance cost.

[0042] The traction link 6 includes a driving rod 602 and a driven rod 601. An angle close to the mobile platform 3 can be formed between the driving rod 602 and the driven rod 601, and the angle is always less than a flat angle. The driven rod 601 is provided with a driving end connected to the radar probe 1, and the driving rod 602 is provided with a connecting end movably connected to the fixed main shaft 5.

[0043] The surface of the fixed main shaft 5 is provided with a slideway. The connecting end can rotate while sliding in the slideway of the fixed main shaft 5, and the driving end passes through the moving guide rail 4 and is rotatably connected to the radar probe 1. Due to the included angle between the driving rod 602 and the driven rod 601 being less than 180° and cooperating with the connecting head at the top of the radar probe 1, when the radar probe 1 is far from the fixed main shaft 5, the detection direction of the radar probe 1 is vertically downward; when the radar probe 1 is close to the fixed main shaft 5, the detection direction of the radar probe 1 turns outwards.

[0044] The fixed main shaft 5 is connected to the center of the upper end of the mobile platform 3, and a coordinate calibration mechanism 7 is provided at the connection between the fixed main shaft 5 and the mobile platform 3. By providing the coordinate calibration mechanism 7 between the fixed main shaft 5 and the mobile platform 3, it is beneficial to perform mechanical calibration after the measuring instrument is installed, ensure that the mobile platform 3 is horizontal and the fixed main shaft 5 is perpendicular to the mobile platform 3, so that the radar probe 1 forms a standard radar reflection area, facilitating the installation and use of the measuring instrument and the establishment of calculation coordinates by the measuring instrument; after the measuring instrument is affected by long-period sea wave impacts, bad weather or even natural disasters, the measuring instrument or the installation platform of the measuring instrument is tilted, and mechanical calibration is performed on the measuring instrument so that the measuring instrument can be put back into use, reducing the use cost of the measuring instrument.

[0045] The coordinate calibration mechanism 7 is used to adjust the relative attitude between the fixed main shaft 5 and the mobile platform 3.

[0046] The fixed main shaft 5 is horizontally provided with an extension support rod on the side, and the extension support rod is used to provide a lateral layout space between the radar probe 1 and the shore-based fixed bracket.

[0047] The shore-based fixed bracket further includes a housing 2. The housing 2 is conical with its small end facing upward. The bottom end of the housing 2 is installed on the upper end 3 of the mobile platform. The mobile guide rail 4 and the traction connecting rod 6 are both located inside the housing 2. The conical housing 2 forms an external protection for the mobile guide rail 4 and the traction connecting rod 6, reducing the impact of salt spray erosion that may prevent the radar probe 1 from changing its array. The outer wall of the conical housing 2 is conducive to guiding the lateral air flow, reducing the influence of strong lateral air flow on the microwave emitted by the radar probe 1, and thus improving the accuracy of wave measurement.

[0048] Since the radar probe 1 needs to be connected to a power source by a cable to form continuous power supply, the housing 2 shields the cable connection, reducing the possibility of poor contact of the cable under the influence of salt spray, thereby stabilizing the radar probe 1 to emit microwaves at an accurate cycle to detect wave information.

[0049] The coordinate calibration mechanism 7 includes a reference plate 701 and surrounding connecting members 702. The number of the connecting members 702 corresponds to that of the mobile guide rails 4. The reference plate 701 is sleeved on the fixed main shaft 5. Both ends of the connecting member 702 are respectively connected to the reference plate 701 and the mobile platform 3. An elastic body 703 is sleeved outside the connecting member 702. One end of the elastic body 703 contacts the reference plate 701, and the other end of the elastic body 703 contacts the mobile platform 3. By using the cooperation of the reference plate 701 and the connecting member 702, the levelness of the mobile platform 3 is adjusted by adjusting the connecting member 702, simplifying the adjustment method for keeping the radar probe 1 at a relatively constant height, simplifying the calibration steps of the measuring instrument, reducing the calibration difficulty of the measuring instrument, and an elastic body 703 is arranged outside the connecting member 702 to increase the resistance of the connecting member 702 during rotation, reducing the vertical displacement of the connecting member 702 under the same torque and improving the operation accuracy during calibration of the measuring instrument; the elastic body 703 can absorb the vibration transmitted from the installation platform of the measuring instrument to the measuring instrument, reducing the influence of the shaking of the radar probe 1 on the radar reflection area and keeping the radar reflection area stationary; by using the reference plate 701 in cooperation with the mobile platform 3, the mobile platform 3 is kept horizontal by keeping the reference plate 701 in a horizontal position, reducing the measurement object of the levelness of the measuring instrument.

[0050] The position of the connecting member 702 is on the extension line of the mobile guide rail 4. By arranging the connecting member 702 on the extension line of the mobile guide rail 4, the corresponding connecting member 702 of the mobile guide rail 4 can reflect the error of the corresponding mobile guide rail 4, or adjusting a certain connecting member 702 can adjust the corresponding mobile guide rail 4 of the connecting member 702, reducing the difficulty in the adjustment process of the measuring instrument.

[0051] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Thus, all changes that fall within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention. Any reference signs in the claims should not be construed as limiting the claims involved.
