Description

Technical Field

[0001] The invention belongs to the technical field of wave measurement, and in particular relates to a fixedly installed radar wave direction, wave height and wave period measuring instrument. Background Art

[0002] With the rapid development of the marine economy, human activities at sea are increasing, and natural disasters such as typhoons and storm surges have a significant impact on the pace of marine development and utilization. The emergence of natural disasters such as typhoons and storm surges will inevitably cause changes in marine observation elements, and it is necessary to observe marine observation elements to carry out forecasting, prevention, disaster prevention, and disaster reduction work for natural disasters. Among the many marine observation elements, waves are the most important and complex marine observation element, and are also one of the important contents of physical oceanography research. It is one of the important input parameters in the fields of marine forecasting, marine engineering, disaster prevention and mitigation, marine rights and interests protection, and navigation safety.

[0003] Ocean waves contain enormous energy, which can cause ships to sway and even cause shipwrecks. They pose a serious threat to marine operations and have a great destructive effect on coastal protection, ports and docks. The use of radar wave meters to conduct research and application of ocean wave measurement can effectively monitor wave information at sea and forecast sea conditions, which is beneficial to improving the port's disaster prevention capabilities, helping to reduce the losses of coastal ports under extreme disaster conditions, and providing protection for the production operations of coastal ports and docks and the safety of people's lives and property. It is of great significance.

[0004] The Korean invention patent with application number KR1020230031032A discloses a wave measuring buoy with solar cells, which includes: a float, which floats on the water surface by buoyancy; a controller, which is connected to the float to measure the wave height of the water surface where the float floats and control the generation of electric energy; and a buffer, which is installed on the float to disperse or absorb the impact applied to the float from the outside, so that it can be stably positioned on the water surface to accurately measure the wave height, and accurately locate the sailing ship by increasing the radar reflection area. This type of wave measuring device in the prior art is suitable for sea surface buoys, and the wave measuring radar is a fixed setting, which requires a predetermined array setting before being deployed. When this type of device is applied to the base station shore, it is impossible to adjust the detection range, which has limitations. Summary of the invention

[0005] The object of the present invention is to provide a fixed-mounted radar wave direction, wave height and wave period measuring instrument with a simple structure, high adaptability to sea surface environment and wave measurement accuracy.

[0006] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: A fixed-mounted radar wave direction, wave height, and wave period measuring instrument comprises: a radar probe and a shore-based fixed bracket, the shore-based fixed bracket comprises a moving mechanism, the moving mechanism comprises a moving platform and a traction link, moving guide rails are evenly arranged above the moving platform, and any moving guide rail is movably connected to the radar probe. The moving guide rails and the traction link cooperate to enable the radar probe to switch between a point array and a triangular array. When the radar probe forms a point array, three radar probes are close to each other, one of which has a detection direction vertically downward, and the other at least two radar probes are installed at an angle to form a triangular radar reflection area, which is suitable for the deployment and use of the measuring instrument near the sea surface. However, since the radar probe of the point array is installed at an angle, the incident angle of the radar reflection area is large, which will generate a large number of clutter signals formed by internal reflections; When the radar probes form a triangular array, the three radar probes are arranged in a triangle and the radar probes are irradiated directly downward. This is suitable for deployment when the measuring instrument is far away 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, wave period, etc. in the radar reflection area. The present invention can switch between a point array and a triangle array, and can be adapted to different height differences between the present invention and the sea surface. It can obtain various wave characteristic elements such as the current wave direction, wave height, wave period, etc. in both stable sea conditions when the sea surface is low and severe sea conditions when the sea surface is high, thereby improving the timeliness and accuracy of natural disaster reports under complex sea conditions. At the same time, since the present invention can switch to a point array mode in 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.

[0007] Preferably, the extension lines of each movable guide rail intersect at the center of the upper end face of the mobile platform, and the radar probe can move in the movable guide rail connected thereto, and the detection direction of the radar probe is arranged downward, and the radar probe is located below the mobile platform. The movable guide rail is arranged on the upper end face of the mobile platform to avoid height differences between the radar probes. At the same time, it is convenient for the coordinate calibration mechanism to indirectly calibrate the position coordinates of all radar probes by calibrating the mobile platform to avoid affecting the measurement results of the measuring instrument; the extension lines of the movable guide rail intersect at the center of the upper end face of the mobile platform, that is, the movable guide rails are evenly distributed around the common intersection point, which is convenient for the radar probes to remain at the vertices of the same equilateral triangle during 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, thereby reducing the installation and use threshold and installation and use cost of the measuring instrument.

[0008] Preferably, the shore-based fixed support also includes a fixed main shaft, and each movable guide rail is movably connected with a corresponding traction link, one end of the traction link is connected to the radar probe, and the other end of the traction link is connected to the fixed main shaft. The fixed main shaft and the traction link are used in combination to make the radar probe move, that is, the vertices of the triangle of the radar reflection area are displaced relative to the center of the triangle, so that the measuring instrument can reset the relevant parameters of the radar reflection area after the radar probe moves, and calculate various wave characteristic elements such as wave direction, wave height, and wave period.

[0009] Preferably, a connector is provided on the top of the radar probe, and the connector has an ear hole that is 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, the pitch angle of the radar probe will change during the movement of the traction link. Furthermore, when the traction link pulls the radar probe inward, that is, when the radar probe approaches the fixed main axis, the detection direction of the radar probe turns outward, so that the radar probe of the measuring instrument can be switched between the point array and the triangular array. Since the radar probes approach each other when the array changes, the detection area formed by them is reduced. The above technical solution can make the radar probes approach each other while flipping and tilting in a direction away from each other, thereby expanding the reduced detection area, that is, by reducing the overlap of the detection area of ​​the radar probes, the detection range is expanded, overcoming the problem of reduced detection area caused by array changes in the prior art, ensuring that the radar probe forms a stable detection area, thereby improving the detection stability of different array modes for sea surface wavelengths; The radar probe is tilted outward through the above scheme, so that the radar probe is relatively concentrated at the lower center of the mobile platform. On the one hand, the overall center of gravity of the device is converged, the suspension stability of the radar probe at the layout is improved, the frequency of strong shaking of the entire device affected by strong airflow is reduced, the connection interference of the traction link is reduced, and the detection stability of the radar probe for wave height and wavelength is improved, ensuring that the radar probe detects wave height, wavelength and other data at a preset height, thereby improving measurement accuracy and authenticity; Since the device is fixedly arranged, when encountering severe weather at sea such as heavy rain, heavy snow, etc., the radar probe is gathered in the middle below the mobile platform by towing the connecting rod, and the mobile platform forms an upper shield for the radar probe, reducing the possibility of damage to the radar probe and reducing maintenance costs.

[0010] Preferably, the traction link includes an active rod and a driven rod, and an angle close to the mobile platform can be formed between the active rod and the driven rod, and the angle is always smaller than the straight 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.

[0011] Preferably, a slideway is provided on the surface of the fixed spindle, and the connection end can rotate while sliding in the slideway of the fixed spindle, and the driving end passes through the movable guide rail and is rotatably connected to the radar probe. Since the opening angle of the active rod and the driven rod is less than 180°, in conjunction with the connector on the top of the radar probe, when the radar probe is away from the fixed spindle, the detection direction of the radar probe is vertically downward; when the radar probe is close to the fixed spindle, the detection direction of the radar probe is turned outward.

[0012] Preferably, the fixed spindle is connected to the center of the upper end of the mobile platform, and a coordinate calibration mechanism is provided at the connection between the fixed spindle and the mobile platform. The use of the coordinate calibration mechanism between the fixed spindle and the mobile platform is conducive to the mechanical calibration of the measuring instrument after installation, ensuring that the mobile platform is horizontal and the fixed spindle is perpendicular to the mobile platform, so that the radar probe forms a standard radar reflection area, which is convenient for the installation and use of the measuring instrument and the establishment of calculated coordinates by the measuring instrument; after the measuring instrument is impacted by long-term waves or bad weather or even natural disasters, the measuring instrument or the installation platform of the measuring instrument tilts, and the measuring instrument is mechanically calibrated so that the measuring instrument can be put back into use, reducing the use cost of the measuring instrument.

[0013] Preferably, the coordinate calibration mechanism is used to adjust the relative posture between the fixed spindle and the mobile platform.

[0014] Preferably, an extended support rod is laterally arranged on the side of the fixed main shaft, and the extended support rod is used to provide a lateral arrangement space for the radar probe and the shore-based fixed bracket.

[0015] Preferably, the shore-based fixed support further comprises a shell, which is conical and has a small end facing upwards, and the bottom end of the shell is mounted on the upper end of the mobile platform, and the mobile guide rail and the traction connecting rod are both located inside the shell. The conical shell forms an external protection for the mobile guide rail and the traction connecting rod, reducing the erosion of salt spray that causes the radar probe to be unable to change its array, and the conical outer wall of the shell is conducive to guiding the lateral airflow, reducing the influence of the strong lateral airflow on the microwave transmission of the radar probe, thereby improving the accuracy of wave measurement; Since the radar probe needs to be connected to a power source via a cable to provide continuous power supply, the shell 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 in an accurate period to detect wave information.

[0016] Since the present invention adopts an adjustable shore-based fixed bracket, it has the following beneficial technical effects: the radar probe carried by the present invention can perform long-term and short-term switching between different modes to adapt to different installation conditions and changes in ocean conditions, and has the following beneficial effects: a coordinate calibration mechanism is adopted to ensure that the mobile platform is horizontal and the fixed main axis is perpendicular to the mobile platform, so that the radar probe forms a standard radar reflection area, which is convenient for the installation and use of the measuring instrument and the establishment of calculated coordinates by the measuring instrument; after the measuring instrument is impacted by long-term waves or bad weather or even natural disasters, the measuring instrument or the mounting platform of the measuring instrument tilts, and the measuring instrument is mechanically calibrated so that the measuring instrument can be put back into use, thereby reducing the cost of using the measuring instrument; switching to the point array mode when a natural disaster approaches can reduce the volume of the present invention and increase the structural strength of the present invention, thereby increasing the service life.

The moving guide rails 4 and the traction link 6 cooperate to enable the radar probe 1 to switch between a point array and a triangular array. When the radar probes 1 form a point array, three radar probes 1 are close to each other, one of which has a detection direction vertically downward, and the other at least two radar probes 1 are installed at an angle to form a triangular radar reflection area, which is suitable for the deployment and use of the measuring instrument near the sea surface. However, since the radar probes 1 of the point array are installed at an angle, the incident angle of the radar reflection area is large, which will generate a large number of clutter signals formed by internal reflections; When the radar probes 1 form a triangular array, the three radar probes 1 are arranged in a triangular shape, and the radar probes 1 are irradiated directly downward, which is suitable for deployment when the measuring instrument is far away 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, wave period, etc. in the radar reflection area; The present invention can switch between a point array and a triangle array, and can be adapted to different height differences between the present invention and the sea surface. It can obtain various wave characteristic elements such as the current wave direction, wave height, wave period, etc. in both stable sea conditions when the sea surface is low and severe sea conditions when the sea surface is high, thereby improving the timeliness and accuracy of natural disaster reports under complex sea conditions. At the same time, since the present invention can switch to a point array mode in 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.

[0021] The extension lines of the movable guide rails 4 intersect at the center of the upper end surface of the movable platform 3. The radar probe 1 can move in the movable guide rails 4 connected thereto. The detection direction of the radar probe 1 is arranged downward, and the radar probe 1 is located below the movable platform 3. The movable guide rails 4 are arranged on the upper end surface of the movable 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 radar probes 1 by calibrating the movable platform 3, so as to avoid affecting the measurement results of the measuring instrument; the extension lines of the movable guide rails 4 intersect at the center of the upper end surface of the movable platform 3, that is, the movable guide rails 4 are evenly distributed at angles around the common intersection point, so that the radar probes 1 can be kept at the vertices of the same equilateral triangle to form a standard radar reflection area during the movement process, so as to avoid the need to adjust the information processing algorithm of the measuring instrument according to the actual radar reflection area before use, thereby reducing the installation and use threshold and installation and use cost of the measuring instrument.

[0022] The shore-based fixed support also includes a fixed main shaft 5, and each movable guide rail 4 is movably connected with a corresponding traction link 6, one end of the traction link 6 is connected to the radar probe 1, and the other end of the traction link 6 is connected to the fixed main shaft 5. The fixed main shaft 5 and the traction link 6 are used to cooperate with each other, so that the radar probe 1 moves, that is, the vertices of the triangle of the radar reflection area are displaced relative to the center of the triangle, so that the measuring instrument can reset the relevant parameters of the radar reflection area after the radar probe 1 moves, and calculate various wave characteristic elements such as wave direction, wave height, and wave period.

[0023] A connector is provided on the top of the radar probe 1, and the connector has an ear hole that is 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, the pitch angle of the radar probe 1 will change during the movement of the traction link 6. Furthermore, when the traction link 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 outward, so that the radar probe 1 of the measuring instrument switches between the point array and the triangular array. Since the radar probes 1 approach each other when the array changes, the detection area formed by them is reduced. The above technical solution can make the radar probes 1 approach each other while flipping and tilting in a direction away from each other, thereby expanding the reduced detection area, that is, by reducing the overlap of the detection area of ​​the radar probe 1, the detection range is expanded, which overcomes the problem of reduced detection area caused by array changes in the prior art, and ensures that the radar probe 1 forms a stable detection area, thereby improving the detection stability of different array modes for sea surface wavelengths; The radar probe 1 is tilted outward through the above scheme, 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 suspension stability of the radar probe 1 at the layout is improved, the frequency of strong shaking of the entire device under the influence of strong airflow 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, thereby improving measurement accuracy and authenticity; Since the device is fixedly arranged, when encountering severe weather at sea such as heavy rain, heavy snow, etc., the radar probe 1 is gathered in the middle below the mobile platform 3 by pulling the connecting rod 6, and the mobile platform 3 forms an upper shield for the radar probe 1, thereby reducing the possibility of damage to the radar probe 1 and reducing maintenance costs.

[0024] The traction link 6 includes an active rod 602 and a driven rod 601.

The driven rod 601 is provided with a driving end connected to the radar probe 1, and the active rod 602 is provided with a connecting end movably connected to the fixed main shaft 5.

[0025] A slideway is provided on the surface of the fixed spindle 5, and the connection end can rotate while sliding in the slideway of the fixed spindle 5, and the driving end passes through the movable guide rail 4 and is rotatably connected to the radar probe 1. Since the opening angle of the active rod 602 and the driven rod 601 is less than 180°, in conjunction with the connector on the top of the radar probe 1, when the radar probe 1 is away from the fixed spindle 5, the detection direction of the radar probe 1 is vertically downward; when the radar probe 1 is close to the fixed spindle 5, the detection direction of the radar probe 1 is turned outward.

[0026] The fixed spindle 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 spindle 5 and the mobile platform 3. The coordinate calibration mechanism 7 is provided between the fixed spindle 5 and the mobile platform 3, which is conducive to the mechanical calibration of the measuring instrument after installation, ensuring that the mobile platform 3 is horizontal and the fixed spindle 5 is perpendicular to the mobile platform 3, so that the radar probe 1 forms a standard radar reflection area, which is convenient for the installation and use of the measuring instrument and the establishment of calculated coordinates by the measuring instrument; after the measuring instrument is impacted by long-term waves or bad weather or even natural disasters, the measuring instrument or the installation platform of the measuring instrument tilts, and the measuring instrument is mechanically calibrated so that the measuring instrument can be put into use again, reducing the use cost of the measuring instrument.

[0027] The coordinate calibration mechanism 7 is used to adjust the relative posture between the fixed spindle 5 and the mobile platform 3 .

[0028] An extended support rod is laterally arranged on the side of the fixed main shaft 5, and the extended support rod is used to provide a lateral arrangement space for the radar probe 1 and the shore-based fixed bracket.

[0029] The shore-based fixed support also includes a shell 2, which is conical and has a small end facing upward. The bottom end of the shell 2 is mounted on the upper end 3 of the mobile platform, and the moving guide rail 4 and the traction link 6 are both located inside the shell 2. The conical shell 2 forms an external protection for the moving guide rail 4 and the traction link 6, reducing the erosion of salt mist that causes the radar probe 1 to be unable to change its array. The outer wall of the conical shell 2 is conducive to guiding the lateral airflow, reducing the influence of the strong lateral airflow on the microwaves sent by the radar probe 1, thereby improving the accuracy of wave measurement; Since the radar probe 1 needs to be connected to a power source by a cable to form a continuous power supply, the shell 2 shields the cable connection to reduce the possibility of poor contact of the cable under the influence of salt spray, thereby stabilizing the radar probe 1 to accurately periodically emit microwaves to detect wave information.

The reference plate 701 and the connecting piece 702 are used in combination, and the horizontality of the mobile platform 3 is adjusted by adjusting the connecting piece 702, which simplifies the adjustment method of maintaining the radar probe 1 at the same relative height, simplifies the calibration steps of the measuring instrument, and reduces the calibration difficulty of the measuring instrument. The elastic body 7003 is arranged outside the connecting piece 702 to increase the resistance of the connecting piece 702 during the rotation process, reduce the vertical displacement of the connecting piece 702 under the same torque, and improve the operating accuracy of the measuring instrument during calibration; the elastic body 7003 can absorb the vibration transmitted from the installation platform of the measuring instrument to the measuring instrument, reduce the influence of the shaking of the radar probe 1 on the radar reflection area, and keep the radar reflection area still; the reference plate 701 is used in combination with the mobile platform 3, and the mobile platform 3 is kept horizontal by keeping the reference plate 701 in a horizontal position, thereby reducing the measurement object of the horizontality of the measuring instrument.

[0031] The position of the connecting member 702 is on the extension line of the moving guide rail 4. The connecting member 702 is arranged on the extension line of the moving guide rail 4, so that the corresponding connecting member 702 of the moving guide rail 4 can reflect the error of the corresponding moving guide rail 4, or adjusting a certain connecting member 702 can adjust the corresponding moving guide rail 4 of the connecting member 702, thereby reducing the difficulty of the measuring instrument adjustment process.
