Description

Technical Field

[0001] This utility model relates to the field of marine navigation technology, specifically to a wind detection and alarm device for marine navigation. Background Technology

[0002] When ships are sailing, they often encounter storms. When a storm comes, the wind is strong. Since people on board are inside the cabin, they cannot perceive the increase in wind force in the external environment in time, so they are notified late. At this time, a wind detection alarm device is needed to notify the people on board in time so that they can make preparations in advance.

[0003] Publication No. CN219590341U discloses a wind detection and alarm device for ship navigation, comprising a device body, a wind passage opening at the bottom of the device body, the cross-sectional shape of the wind passage opening being cross-shaped, an auxiliary support rod being disposed in the middle position inside the wind passage opening, the auxiliary support rod being fixedly connected to the device body, an installation cavity being disposed at the top inside the device body, a central controller being disposed at the bottom inside the installation cavity, and an alarm light being disposed on one side of the device body.

[0004] Although the aforementioned prior art uses air passage openings, allowing wind to pass through the cross-shaped openings when it exerts force on the main body of the device, thus reducing the force of the wind on the main body and making it less likely to be blown over or broken by the wind, the support columns on both sides of the air passage openings are still made of rigid materials, and the auxiliary support rod is located at the center of the cross-shaped air passage openings. When wind blows directly across the arc surface of a certain support column, the wind blows from the air passage openings on both sides of that support column in a mutually perpendicular direction towards the auxiliary support rod. At this time, due to the obstruction of the auxiliary support rod and the perpendicular angle between the two sets of airflows flowing into the air passage openings, turbulent airflow is easily formed inside, making that side a high-pressure state. At the same time, because the auxiliary support rod obstructs the incoming airflow, after the airflow is discharged from the air passage opening on the air outlet side, the side of the auxiliary support rod away from the air inlet forms a vacuum low-pressure state with the air passage opening. As the wind speed increases, the pressure difference increases, and the pressure applied to the support column also increases. If the pressure value exceeds the rigidity requirement of the support column, the support column can be bent.

[0005] Meanwhile, the alarm light is located on one side of the main body of the device, making it difficult for personnel to observe its status when standing on the side of the device furthest from the light. Therefore, a wind-powered detection and alarm device for marine navigation is needed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a wind detection and alarm device for ship navigation, so as to solve the above-mentioned defects caused by the prior art.

[0007] A wind detection and alarm device for ship navigation includes a base platform, a boss mounted on the upper end of the base platform, a support column rotatably connected to the boss, a three-color audible and visual alarm mounted on the boss, a frustum mounted on the support rod of the three-color audible and visual alarm, a support platform mounted on the frustum, a cup-type anemometer mounted on the support platform, a ring block provided on the bottom side of the frustum, the support column rotatably engaging with the ring block, and a wind vane mounted on one side of the support column.

[0008] Preferably, a controller is installed inside the base, and the three-color audible and visual alarm and the wind cup-type wind speed sensor are electrically connected to the controller via a first wire and a second wire, respectively.

[0009] Preferably, the two ends of the support column are respectively provided with a first circular groove and a second circular groove that rotatably cooperate with the boss and the ring block, and the two ends of the support column are respectively provided with support plates.

[0010] Preferably, the wind vane has a conical opening on the windward side to facilitate airflow diversion.

[0011] Preferably, the support platform includes a mounting platform installed on a frustum-shaped mesh structure, and an annular frustum is mounted on the mounting platform, with the wind cup anemometer mounted on the annular frustum.

[0012] The advantages of this utility model are as follows: By having the wind vane drive the support column to rotate around the boss and the ring block respectively, this utility model ensures that the smooth surface of the support plate is parallel to the wind direction, thereby ensuring that strong winds do not blow perpendicularly to the curved surface of the support plate, reducing the impact force of the airflow. At the same time, the airflow velocity inside the two support plates is relatively fast, and the two support plates will form a low-pressure area. One side of the support plate is a smooth surface and the other side is a curved surface, thereby ensuring that when the airflow passes through the support plate, it will generate an inward lift force, thereby offsetting the external pressure on the support plate and preventing the support plate from deforming.

[0013] This invention uses a three-color sound and light alarm to make the flashing of the colored light visible from different angles, thus avoiding blind spots. Attached Figure Description

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1 to 4 As shown, a wind detection and alarm device for ship navigation includes a base 1, a boss 2 mounted on the upper end of the base 1, a support column 3 rotatably connected to the boss 2, a three-color audible and visual alarm 4 mounted on the boss 2, a truncated cone 5 mounted on the support rod of the three-color audible and visual alarm 4, a support platform 6 mounted on the truncated cone 5, a wind cup-type anemometer 7 mounted on the support platform 6, a ring block 8 provided on the bottom side of the truncated cone 5, the support column 3 rotatably engaging with the ring block 8, and a wind vane 9 mounted on one side of the support column 3. The truncated cone 5 is fixedly connected to the support rod of the three-color audible and visual alarm 4 by a connecting block, and the support rod of the three-color audible and visual alarm 4 has a hollow structure. The three-color audible and visual alarm 4 is equipped with red, green, and yellow lights, which are stacked and arranged so that the flashing of the lights can be seen from different angles, and an audible alarm can be emitted.

[0021] In this embodiment, a controller 10 is installed inside the base 1. The tri-color audible and visual alarm 4 and the wind cup-type anemometer 7 are electrically connected to the controller 10 via a first wire 11 and a second wire 12, respectively. The controller 10 is electrically connected to the ship's power supply. The second wire 12 extends into the support rod of the tri-color audible and visual alarm 4 and is connected to the controller 10.

[0022] In this embodiment, the two ends of the support column 3 are respectively provided with a first circular groove 13 and a second circular groove 14 that rotatably engage with the boss 2 and the ring block 8, and the two ends of the support column 3 are respectively provided with support plates 15. The support plates 15 and the wind vane 9 form a triangle and serve to support the bottom surface of the frustum 5.

[0023] In this embodiment, the wind vane 9 has a conical opening on its windward side to facilitate airflow diversion. The conical opening serves to break the wind.

[0024] In this embodiment, the support platform 6 includes a mounting platform 16 mounted on a mesh structure of the frustum 5. An annular frustum 17 is mounted on the mounting platform 16, and the cup-type anemometer 7 is mounted on the annular frustum 17. The mounting platform 16 is fixedly mounted to the frustum 5, and the mounting platform 16 has a mesh structure to facilitate airflow through the interior. The circular groove in the middle of the annular frustum 17 facilitates the passage of the second wire 12.

[0025] The working principle of this utility model is as follows: the airflow drives the support column 3 to rotate around the boss 2 and the ring block 8 respectively through the wind vane 9, thereby ensuring that the smooth surface of the support plate 15 is parallel to the wind direction. The airflow detects the wind speed through the wind cup type wind speed sensor 7 and inputs the wind speed data into the controller 10. When the wind speed is too fast, the controller 10 outputs an alarm signal, causing the red light of the three-color sound and light alarm 4 to light up and emit an audible alarm.

[0026] This invention ensures that the smooth surface of the support plate 15 is parallel to the wind direction by driving the support column 3 to rotate around the boss 2 and the ring block 8 respectively, thereby preventing strong winds from blowing perpendicularly onto the arc surface of the support plate 15 and reducing the impact force of the airflow. At the same time, the airflow velocity inside the two support plates 15 is relatively fast, and the two support plates 15 will form a low-pressure area. One side of the support plate 15 is a smooth surface and the other side is an arc surface, thereby ensuring that when the airflow flows through the support plate 15, it will generate an inward lift force, thereby offsetting the external pressure on the support plate 15 and preventing the support plate 15 from deforming.

[0027] This invention uses a three-color sound and light alarm 4, with three colors of lights stacked together, so that the flashing of the lights can be observed from different angles, avoiding blind spots.

[0028] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
