Description

Technical Field

[0001] This invention relates to the field of marine wind measurement technology, and in particular to a marine shipborne wind measurement device and method. Background Technology

[0002] Accurate wind direction and speed data are fundamental to various marine operations and are of great significance for ship navigation, maritime search and rescue, carrier-based aircraft take-off and landing, and typhoon prevention and disaster relief.

[0003] During wind measurement at sea, commonly used wind measuring devices are often affected by the spatial movement of ships in various directions. For example, wind speed and direction instruments cannot maintain a vertical state, resulting in inaccurate measurement results. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing wind measuring devices that cannot maintain a vertical state, resulting in inaccurate measurement results, and to provide a marine shipborne wind measuring device and wind measuring method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A marine shipborne wind measurement device includes a left fixed plate on the left edge of the upper surface of the deck of a ship, a right fixed plate on the right edge of the upper surface of the deck of the ship, two connecting mechanisms respectively on the left and right fixed plates, a left and right vertical rod limiting sleeves respectively connected to the two connecting mechanisms, a left and right square vertical rods respectively slidably connected to the left and right vertical rod limiting sleeves, a left and right counterweight blocks respectively located at the lower ends of the left and right square vertical rods, and a left and right airbags respectively located at the upper ends of the left and right square vertical rods. A left and right hanging crossbar are separately installed on the upper part of the left and right square uprights, respectively. A downwardly arched arc-shaped track is located between the right end of the left hanging crossbar and the left end of the right hanging crossbar. A measuring mechanism is installed on the arc-shaped track. The measuring mechanism includes a front clamping plate, a rear clamping plate, a bearing between the front and rear clamping plates, a rotating wheel on the bearing, a mounting base at the upper part of the front and rear clamping plates, an anemometer on the mounting base, and a gravity block at the lower end of the front and rear clamping plates. The rotating wheel makes rolling contact with the upper surface of the arc-shaped track, and the arc-shaped track is located between the lower parts of the front and rear clamping plates.

[0007] The downward-arching arc-shaped track located between the left and right hanging crossbars provides support for the rotating wheel of the measuring mechanism. The front and rear clamps provide constraints on the rotating wheel, allowing the roller to move along the arc-shaped track under the gravity provided by the gravity block. This keeps the measuring mechanism vertical, thus ensuring that the anemometer remains in a vertical state and guarantees the accuracy of the measured wind speed and direction data.

[0008] Therefore, this invention effectively reduces the impact of ship's spatial motion on the wind measuring device, ensuring that the wind speed and direction instrument always remains vertical, thus guaranteeing the requirement for accurate measurement, high measurement precision, and good measurement stability.

[0009] Preferably, the left end of the left hanging crossbar is rotatably connected to the upper part of the left square upright, and the right end of the right hanging crossbar is rotatably connected to the upper part of the right square upright; the two connecting mechanisms are rotatably connected to the left upright limiting sleeve and the right upright limiting sleeve respectively; and scales are provided on the opposite sides of the left square upright and the right square upright.

[0010] When the ship is sailing in the sea or when it is stopped in the sea with large waves, the waves cause the ship to sway. However, because the two connecting mechanisms are rotatably connected to the left and right upright limit sleeves respectively, the swaying of the ship will not affect the verticality of the left and right square uprights.

[0011] The waves cause the left and right square poles to undulate, resulting in changes in the height of their upper ends. At this time, the wheel rolls on the surface of the arc-shaped track. Under the weight of the gravity block and the constraints of the front and rear clamps, the anemometer remains vertical. The anemometer measures the wind speed and direction, obtaining accurate wind speed and direction data.

[0012] Preferably, a left balance rope is provided between the mounting base and the left square upright, and a right balance rope is provided between the mounting base and the right square upright, with the left and right balance ropes being of equal length; the bearings are connected to the front and rear clamping plates respectively by a set of through screws; the lower parts of the front and rear clamping plates are connected to the gravity block by a suspension rope.

[0013] The placement of the left and right balance ropes constrains the mounting base to the middle position between the left and right balance ropes, further increasing the stability of the measuring mechanism and keeping the anemometer vertical, thereby ensuring the accuracy of the measurement data.

[0014] Preferably, the left end of the arc-shaped track is provided with a left connecting section, and the right end of the arc-shaped track is provided with a right connecting section. The left connecting section is connected to the right part of the left hanging crossbar through a left arc rod reset pivot and a left arc rod positioning pin, and the right connecting section is connected to the left part of the right hanging crossbar through a right arc rod reset pivot and a right arc rod positioning pin.

[0015] Preferably, the connecting mechanism includes a rotating plate, a rotating plate shaft passing through and fixedly connected to the rotating plate, and a limiting crossbar; the limiting crossbar is rotatably connected to the rotating plate shaft via a crossbar reset shaft; the two connecting mechanisms are symmetrically arranged, the left fixed plate is fixedly connected to the rotating plate of the connecting mechanism above it via a left crossbar positioning pin, and the left fixed plate is rotatably connected to the rotating plate shaft of the connecting mechanism above it; the right fixed plate is fixedly connected to the rotating plate of the connecting mechanism above it via a right crossbar positioning pin, and the right fixed plate is rotatably connected to the rotating plate shaft of the connecting mechanism above it; the left end of the limiting crossbar of the connecting mechanism on the left fixed plate is rotatably connected to the left upright limiting sleeve via a left longitudinal rotating shaft, and the right end of the limiting crossbar of the connecting mechanism on the right fixed plate is rotatably connected to the right upright limiting sleeve via a right longitudinal rotating shaft.

[0016] After removing the left arc rod positioning pin, right arc rod positioning pin, left crossbar positioning pin, and right crossbar positioning pin, rotating the left hanging crossbar, right hanging crossbar, and two limiting crossbars allows the left and right square uprights to be retracted to the side of the boat, facilitating the boat's passage through narrow waters and making it widely applicable.

[0017] Preferably, the left square upright is connected to the left counterweight via a left suspension cable, and the right square upright is connected to the right counterweight via a right suspension cable.

[0018] The placement of the left and right suspension cables ensures that the left and right counterweights are far from the sea surface, minimizing their impact from waves and allowing the left and right square poles to remain stably suspended in the seawater.

[0019] A wind measurement method for a marine shipborne wind measuring device includes the following steps:

[0020] Step 1: When the boat is stationary in calm seawater, the staff fill the two airbags with hydrogen or helium. During the inflation process, observe the scale values ​​on the opposite sides of the left and right square poles and adjust the inflation amount in the two airbags until the upper height of the two airbags is the same.

[0021] The left square upright is vertically suspended in the seawater by the left counterweight and the left airbag; the right square upright is vertically suspended in the seawater by the right counterweight and the right airbag.

[0022] Step 2: The boat is moored in calm seawater, the anemometer is kept vertical, and the anemometer measures the wind speed and direction.

[0023] Step 3: When the boat is sailing in the sea or when it is stopped in the sea with large waves, the waves cause the boat to sway. Since the two connecting mechanisms are rotatably connected to the left and right upright limit sleeves respectively, the swaying of the boat will not affect the verticality of the left and right square uprights.

[0024] The waves cause the left and right square poles to undulate, resulting in changes in the height of their upper ends. At this time, the wheel rolls on the surface of the arc-shaped track. Under the weight of the gravity block and the constraints of the front and rear clamps, the anemometer remains vertical. The anemometer measures the wind speed and direction, obtaining accurate wind speed and direction data.

[0025] Preferably, a left balance rope is provided between the mounting base and the left square upright, and a right balance rope is provided between the mounting base and the right square upright, with the left and right balance ropes being of equal length; the wheel rolls on the surface of the arc-shaped track, and under the gravity of the gravity block and the constraint of the front and rear clamping plates, the anemometer maintains a vertical state by the following steps:

[0026] The mounting base is constrained to the middle position between the left and right balance ropes. The wheel rolls on the surface of the arc-shaped track. Under the gravity of the gravity block and the constraint of the front and rear clamps, the anemometer remains vertical.

[0027] Therefore, the present invention has the following beneficial effects: it effectively reduces the impact of ship movement on the wind measuring device, has high measurement accuracy and good measurement stability; the left and right square poles can be retracted to the side of the ship, making it easier for the ship to pass through narrow waters, and has a wide range of applications.
