Description
Technical Field
[0001] This utility model belongs to the field of shore markers for ship navigation, and specifically relates to a waterway shore marker with a large-scale water flow velocity monitoring function. Background Technology
[0002] The main technologies for collecting inland waterway flow velocity data are shipborne ADCP (Advanced Hydrological Computing Rate) surveys and real-time multi-element hydrological data acquisition using buoys. Shipborne ADCP surveys provide high accuracy and stability. However, this method is time-consuming, inefficient, and difficult to implement for high-frequency monitoring. Furthermore, this method poses safety hazards to workers when applied to steep, fast-flowing river sections. Real-time multi-element hydrological data acquisition using buoys can only collect flow velocity information at single points; a multi-point data network is necessary for the data to be usable. However, the construction, operation, and maintenance costs of such monitoring networks are high. Utility Model Content
[0003] In view of the above problems, this application provides a waterway shore marker with a large-scale water flow velocity monitoring function, which can realize real-time monitoring of water flow velocity over a large area, reduce the risk of personnel operation, and save maintenance costs.
[0004] This application provides a waterway shore marker with a wide-area water flow velocity monitoring function, including a tower, a radar wave monitoring device, a marker body, and a navigation light. The tower is located on one side of the water area; the radar wave monitoring device is located at the top of the tower, and is used to emit electromagnetic wave pulses into the water area and to receive electromagnetic wave pulses reflected by the water area; the marker body is located at the top of the tower and is situated to one side of the radar wave monitoring device; the navigation light is located at the top of the tower and is used to provide light into the water area.
[0005] Specifically, by installing radar wave monitoring devices on the towers of shore markers, firstly, the height of the towers allows the radar wave monitoring devices to emit electromagnetic pulses over a wider area of the waterway and receive electromagnetic pulses reflected from the water over a wider area. This enables monitoring of the current velocity in the waterway over a broader range. Secondly, the height of the towers reduces interference from the shoreline environment, such as rocks and buildings, on the electromagnetic pulses, resulting in stable and comprehensive monitoring data. Thirdly, it avoids safety risks during water operations, especially in steep and fast-flowing waters, improving the safety of equipment and personnel. Furthermore, the installation on the towers facilitates maintenance of the radar wave monitoring devices during shore marker inspections, enabling real-time monitoring of water flow velocity over a wide area, reducing operational risks, and saving maintenance costs.
[0006] In some embodiments, the radar wave monitoring device includes a first mounting frame, a transmitting antenna, a receiving antenna, and a controller. The first mounting frame is disposed at the top of the tower; the transmitting antenna is disposed in the middle of the first mounting frame and is used to transmit electromagnetic wave pulses to the water area; the receiving antenna is disposed at the top of the first mounting frame and is used to receive electromagnetic wave pulses reflected by the water area; the controller is electrically connected to the transmitting antenna and the receiving antenna respectively.
[0007] In the above technical solution, the transmitting antenna is located in the middle of the first mounting bracket, and the receiving antenna is located at the top of the first mounting bracket. On the one hand, this makes the transmitting antenna closer to the surface of the top of the tower, which can reduce the interference of the surface reflection of the top of the tower on the receiving antenna to receive electromagnetic pulse waves and improve the signal-to-noise ratio of electromagnetic pulse waves. On the other hand, the fact that the transmitting antenna is closer to the water surface than the receiving antenna can optimize the propagation path of electromagnetic pulse waves in the water and improve measurement accuracy.
[0008] In some embodiments, the first mounting bracket includes a fixed base and a support. The fixed base is detachably disposed at the top of the tower body; the support extends along the direction of gravity, one end of the support is detachably disposed at the fixed base, the receiving antenna is detachably disposed at the other end of the support, and the transmitting antenna is detachably disposed at the middle of the support.
[0009] In the above technical solution, the first mounting bracket is a split design including a fixed base and a bracket, and the fixed base and the bracket are detachably connected. The bracket is detachably connected to the transmitting antenna and the receiving antenna, respectively, so as to facilitate the disassembly and transportation of the radar wave monitoring device, reduce its transportation difficulty, and increase the applicable environment of the radar wave monitoring device.
[0010] In some embodiments, the receiving antenna is located above the navigation light and on a plane parallel to the direction of gravity, and the orthographic projection of the receiving antenna does not overlap with the orthographic projection of the navigation light.
[0011] In the above technical solution, the receiving antenna is located above the navigation light and on a plane parallel to the direction of gravity. The orthographic projection of the receiving antenna does not overlap with the orthographic projection of the navigation light, thereby reducing the risk of the receiving antenna blocking the light emitted by the navigation light, and thus reducing the risk of the radar wave monitoring device interfering with the normal use of the navigation light.
[0012] In some embodiments, the transmitting antenna is located on one side of the navigation light and faces the water area.
[0013] In the above technical solution, the transmitting antenna is located on one side of the navigation light and faces the water, thereby reducing the risk of the transmitting antenna blocking the light emitted by the navigation light, and thus reducing the risk of the radar wave monitoring device interfering with the normal use of the navigation light.
[0014] In some embodiments, the marker is located at the geometric center of the top of the tower.
[0015] In the above technical solution, the marker is set at the geometric center of the top of the tower, which makes it easier for ships to observe the marker.
[0016] In some embodiments, the target body includes a second mounting bracket and a main body. The second mounting bracket is disposed at the top of the tower body; the main body is disposed at the other end of the second mounting bracket away from the tower body and above the radar wave monitoring device, such that the orthographic projection of the main body overlaps the orthographic projection of the second mounting bracket in a plane perpendicular to the direction of gravity.
[0017] In the above technical solution, on a plane perpendicular to the direction of gravity, the orthographic projection of the main body covers the orthographic projection of the second mounting frame, that is, the main body has a certain volume, which facilitates the observation of the target body by the sailing ship.
[0018] In some embodiments, the body is cylindrical, and the axis of the body is parallel to the direction of gravity.
[0019] In the above technical solution, the shape of the target body is the same when it is observed in any horizontal direction, which makes it easier for ships to observe the target body.
[0020] In some embodiments, the waterway shore marker with a wide-area water flow velocity monitoring function also includes a solar panel. The solar panel is disposed at the top of the tower and electrically connected to the radar wave monitoring device, and the solar panel is used to provide power to the radar wave monitoring device.
[0021] In the above technical solution, the solar panel is set at the top of the tower and is used to provide power to the radar wave monitoring device. On the one hand, this eliminates the need for additional circuitry for the radar wave monitoring device. On the other hand, by taking advantage of the height of the tower, the interference of the shore environment such as rocks and buildings on sunlight is reduced, allowing the solar panel to fully absorb sunlight and provide power to the radar wave monitoring device.
[0022] In some embodiments, the solar panel and the navigation light are located on opposite sides of the tower.
[0023] In the above technical solution, the solar panel and the navigation light are located on opposite sides of the tower, thereby reducing the risk of the solar panel blocking the light emitted by the navigation light, and thus reducing the risk of the solar panel interfering with the normal use of the navigation light.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0033] Example 1:
[0034] The main technologies for collecting inland waterway flow velocity data are shipborne ADCP (Advanced Hydrological Computing Rate) surveys and real-time multi-element hydrological data acquisition using buoys. Shipborne ADCP surveys provide high accuracy and stability. However, this method is time-consuming, inefficient, and difficult to implement for high-frequency monitoring. Furthermore, this method poses safety hazards to workers when applied to steep, fast-flowing river sections. Real-time multi-element hydrological data acquisition using buoys can only collect flow velocity information at single points; a multi-point data network is necessary for the data to be usable. However, the construction, operation, and maintenance costs of such monitoring networks are high.
[0035] To solve the above technical problems, refer to Figure 1 This embodiment provides a waterway shore marker with a large-area water flow velocity monitoring function, including a tower 1, a radar wave monitoring device 2, a marker body 3, and a navigation light 4. The tower 1 is located on one side of the water area; the radar wave monitoring device 2 is located at the top of the tower 1, and is used to emit electromagnetic wave pulses into the water area and receive electromagnetic wave pulses reflected by the water area; the marker body 3 is located at the top of the tower 1 and to one side of the radar wave monitoring device 2; the navigation light 4 is located at the top of the tower 1 and is used to provide light into the water area. The tower 1 serves as a fixed reference point among the shore markers.
[0036] The marker 3 can take the form of a column, buoy, etc., and its main function is to provide navigation reference for ships.
[0037] A navigation light 4 is a landmark lighting device used for navigation, typically installed on the tower 1 of a shore marker, providing navigational reference for ships at night or in low visibility conditions. Through specific colors, flashing frequencies, and light intensities, the navigation light 4 helps ships identify channels, hazardous areas, or port entrances, ensuring safe navigation.
[0038] Specifically, by installing a radar wave monitoring device 2 on the tower 1 of the shore marker, firstly, the height of the tower 1 allows the radar wave monitoring device 2 to emit electromagnetic wave pulses into the water over a wider area and receive electromagnetic wave pulses reflected from the water over a wider area. This enables monitoring of the current velocity in the waterway over a wider range. Secondly, the height of the tower 1 reduces interference from the shore environment, such as rocks and buildings, on the electromagnetic wave pulses, resulting in stable and comprehensive monitoring data. Thirdly, it avoids safety risks during water operations, especially in steep and fast-flowing waters, improving the safety of the equipment and ensuring the safety of monitoring personnel. Furthermore, its placement on the tower 1 facilitates maintenance of the radar wave monitoring device 2 during shore marker inspections and repairs, thus reducing maintenance costs.
[0039] Please refer to Figure 2 The radar wave monitoring device 2 includes a first mounting frame 21, a transmitting antenna 22, a receiving antenna 23, and a controller 24. The first mounting frame 21 is located at the top of the tower body 1; the transmitting antenna 22 is located in the middle of the first mounting frame 21 and is used to transmit electromagnetic wave pulses into the water area; the receiving antenna 23 is located at the top of the first mounting frame 21 and is used to receive electromagnetic wave pulses reflected from the water area; the controller 24 is electrically connected to the transmitting antenna 22 and the receiving antenna 23 respectively.
[0040] For example, transmitting antenna 22 can be used to transmit P-band pulses, and receiving antenna 23 can be used to receive reflected P-band pulses. P-band pulses generally refer to electromagnetic wave pulses used in radar systems, with a frequency range between 230MHz and 1000MHz. They have a longer wavelength, stronger anti-interference ability, and lower resolution, making them suitable for detecting large areas of terrain.
[0041] The controller 24 is used to send instructions to the transmitting antenna 22 to cause the transmitting antenna 22 to emit P-band pulses, and to receive the reflected P-band pulses received by the antenna 23 to calculate the water flow velocity in the water area.
[0042] Specifically, transmitting antenna 22 emits P-band pulses, and receiving antenna 23 receives the P-band pulses reflected from the river surface. Controller 24 uses the Bragg scattering principle to determine the river's flow velocity and direction by analyzing the frequency changes of the reflected P-band pulses, generating flow velocity and direction data. This monitoring data is then transmitted to a data center or control center via a communication module.
[0043] Furthermore, the receiving antenna 23 can be multiple antennas spaced around the first mounting bracket 21, which facilitates receiving reflected electromagnetic pulse waves over a wider range.
[0044] In this technical solution, the transmitting antenna 22 is located in the middle of the first mounting bracket 21, and the receiving antenna 23 is located at the top of the first mounting bracket 21. On the one hand, this makes the transmitting antenna 22 closer to the surface of the top of the tower body 1, which can reduce the interference of the surface reflection of the top of the tower body 1 on the receiving antenna 23 receiving electromagnetic pulse waves and improve the signal-to-noise ratio of electromagnetic pulse waves. On the other hand, the fact that the transmitting antenna 22 is closer to the water surface than the receiving antenna 23 can optimize the propagation path of electromagnetic pulse waves in the water and improve the measurement accuracy.
[0045] Please refer to Figure 2 The first mounting bracket 21 includes a fixed base 211 and a support 212. The fixed base 211 is detachably mounted on the top of the tower body 1; the support 212 extends along the direction of gravity, with one end of the support 212 detachably mounted on the fixed base 211, the receiving antenna 23 detachably mounted on the other end of the support 212, and the transmitting antenna 22 detachably mounted in the middle of the support 212. All of the above detachable mountings are achieved by screw connections; for example, the controller 24 is detachably mounted on the support 212.
[0046] The first mounting bracket 21 is a split design including a fixed base 211 and a bracket 212. The fixed base 211 and the bracket 212 are detachably connected. The bracket 212 is detachably connected to the transmitting antenna 22 and the receiving antenna 23, respectively, so as to facilitate the disassembly and transportation of the radar wave monitoring device 2, reduce its transportation difficulty, and increase the applicable environment of the radar wave monitoring device 2.
[0047] Please refer to Figure 3 The receiving antenna 23 is located above the navigation light 4, and on a plane parallel to the direction of gravity, the orthographic projection of the receiving antenna 23 does not overlap with the orthographic projection of the navigation light 4.
[0048] In this technical solution, the receiving antenna 23 is located above the navigation light 4 and on a plane parallel to the direction of gravity. The orthographic projection of the receiving antenna 23 does not overlap with the orthographic projection of the navigation light 4, thereby reducing the risk of the receiving antenna 23 blocking the light emitted by the navigation light 4, and thus reducing the risk of the radar wave monitoring device 2 interfering with the normal operation of the navigation light 4. Also, please refer to... Figure 2 4. The transmitting antenna 22 is located on one side of the navigation light 4 and faces the water, thereby reducing the risk of the transmitting antenna 22 blocking the light emitted by the navigation light 4, and thus reducing the risk of the radar wave monitoring device 2 interfering with the normal use of the navigation light 4.
[0049] For further details, please refer to Figure 4 The marker 3 is located at the geometric center of the top of the tower 1, so as to facilitate the observation of the marker 3 by navigating ships.
[0050] Please refer to Figure 3 and Figure 4The target body 3 includes a second mounting frame 31 and a main body 32. The second mounting frame 31 is disposed at the top of the tower body 1; the main body 32 is disposed at the other end of the second mounting frame 31 away from the tower body 1 and is located above the radar wave monitoring device 2. On a plane perpendicular to the direction of gravity, the orthographic projection of the main body 32 covers the orthographic projection of the second mounting frame 31.
[0051] To show the extent of the second mounting bracket 31, please refer to... Figure 4 The area of the second mounting bracket 31 is marked with a dashed line in the figure. It should be noted that the dashed line is only for the purpose of showing the area of the second mounting bracket 31 and does not represent any other meaning.
[0052] In this technical solution, the main body 32 is cylindrical, the axis of the main body 32 is parallel to the direction of gravity, and on the plane perpendicular to the direction of gravity, the orthographic projection of the main body 32 covers the orthographic projection of the second mounting frame 31. That is, the main body 32 has a certain volume, so that when the main body 32 is observed in any horizontal direction, the shape of the main body 32 is the same, which facilitates the observation of the target body 3 by the ship.
[0053] Example 2:
[0054] The only difference between this embodiment and Embodiment 1 is that, referring to... Figure 4 The waterway shore marker with a wide-area water flow velocity monitoring function also includes a solar panel 5. The solar panel 5 is installed at the top of the tower 1 and is electrically connected to the radar wave monitoring device 2. The solar panel 5 is used to provide power to the radar wave monitoring device 2.
[0055] Solar panel 5 (also known as solar panel or photovoltaic panel) is a device that converts solar energy into electrical energy. It is widely used in power generation, energy storage and power supply. In this technical solution, solar panel 5 is set at the top of tower 1 and is used to provide power to radar wave monitoring device 2. On the one hand, this eliminates the need for additional circuitry in radar wave monitoring device 2. On the other hand, by taking advantage of the height of tower 1, the interference of the shore environment such as rocks and buildings on sunlight is reduced, thereby enabling solar panel 5 to fully absorb sunlight and provide power to radar wave monitoring device 2.
[0056] Specifically, the solar panel 5 and the navigation light 4 are located on opposite sides of the tower body 1, thereby reducing the risk of the solar panel 5 blocking the light emitted by the navigation light 4, and thus reducing the risk of the solar panel 5 interfering with the normal use of the navigation light 4.
[0057] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.
[0058] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
