Detailed Description
The embodiment of the application provides a not long-stitch-frame wind speed measurement system for measure wind speed, especially be used for measuring marine wind speed.
The wind power development firstly needs to evaluate the wind resources of the area. In order to accurately grasp the change characteristics of wind in a sea area and provide necessary data support for offshore wind power development, the primary step before development is to carry out wind measurement work of a specified sea area. The offshore anemometer tower or the laser radar is a traditional device for offshore anemometer work at the present stage.
Current wind-finding radars are inherently expensive and need to be mounted on some fixed platform, or be of the floating type. The anemometer tower is mainly fixed at a certain point position by utilizing a truss structure, concrete and the like through offshore construction operation, and the construction period is long. No matter which mode, anemometry cost is all comparatively expensive, and offshore anemometry tower's the price of setting up is higher to ten million grades, and the construction cycle is long, and inconvenient transportation. The offshore anemometer tower is high in dismantling cost after being built.
In short, the conventional wind measuring device has a large defect in terms of cost, construction period, and secondary recycling.
Therefore, the application provides a low-cost not have long-running truss's wind speed measurement system, can measure the marine wind speed.
Referring to fig. 1, an embodiment of a wind speed measurement system provided by the present application includes a fixing device 10, a connecting device 20, a measuring device 30, and a power device 40. During wind measurement, the power device 40 floats in the air, the fixing device 10 is arranged on the sea surface or under the sea surface, the fixing device 10 is connected with the measuring devices 30 through the connecting device 20, a plurality of measuring devices are arranged between the power device 40 and the fixing device 10, and the measuring devices 30 are also connected through the connecting device 20.
And a power device 40 is arranged at the top end of the wind speed measuring system. The power plant 40 is filled with helium or other gas so that the power plant 40 has an upward buoyancy. The power unit 40 is connected to a measuring device 30 via a connecting device 20. The power source of the power plant 40 may also be lift provided by a power machine such as a propeller or an ejector, as is technically feasible.
The power unit 40 is connected to a measuring device 30 via a connecting device 20. In order to avoid that the measuring device 30 rotates due to the wind speed, it is preferable to design the measuring device as a sphere or other shape with small wind resistance, so that the force applied by the measuring device 30 on the windward side is substantially uniform. The wind speed measuring system comprises a plurality of measuring devices, wherein each measuring device 30 is connected with other measuring devices 30, wherein the measuring device 30 with the highest height is connected with a power device 40 through a connecting device 20, the measuring device 30 with the lowest height is connected with a fixing device 10 in the sea, and each other measuring device 30 is connected with the other two measuring devices 30 in turn through the connecting device 30. In a windless state, a floating power device 40, a plurality of measuring devices 30 and a fixing device 10 in the sea are sequentially arranged in the wind speed measuring system from top to bottom, the devices are sequentially connected through a connecting device 30, the projections of the devices on the ground are at the same position, and the position of the measuring device 30 can be called as the original point.
In particular, the connection means 30 may be a flexible cable, or the connection means 30 may be a rigid connecting rod, connected to other devices by a buckle. When the cross wind passes, the measuring device 30 is blown away from the original position, and the height and position of the measuring device are changed. Alternatively, the connection device 30 may have a certain lift force, for example, the connection device 30 itself is hollow, and helium or other gas with a smaller density is filled in the connection device 30, so that the connection device 30 and the power device 40 together provide the lift force for the wind speed measuring system.
The fixture 10 is primarily intended to function as a fixture for maintaining the anemometry system in a fixed position or sea area so that it is not carried away by sea winds or ocean currents. For example, the fixture 10 may be a caisson which is submerged when the anemometry system is towed to a designated sea area; alternatively, the fixture 10 is an anchor that sinks the fixture 10 into the sea floor during wind logging. The fixture 10 may also be used as a single fixture to secure the entire anemometry system to a vessel, anchor, or other floating platform. The specific form of the fixing device 10 is not limited herein.
Referring to fig. 2, when cross wind is present only at a low altitude, the measuring device 30 is blown away from the origin. If the cross wind speed is higher at high altitude and the cross wind speed is lower at lower altitude, refer to fig. 3. In addition, in special cases, if there is not only crosswind but also an upward air flow from below to above, it may cause the measuring device 30 to be blown to a higher level than the power device 40, but it does not affect the normal operation of the system. The measuring device 30 is an important part of the present application, and referring to fig. 5, the connecting device 20 is disposed at two ends of the measuring device 30, and the measuring device 30 may include a measuring unit and a balancing unit. The measuring unit is essentially provided with a plurality of sensors for measuring, on the one hand, the wind speed around the measuring device 30 and, on the other hand, the distance by which the measuring device 30 is offset with respect to the origin and the current height. Specifically, a plurality of hot-wire anemometers or laser anemometers may be disposed on the measurement device 30, and the wind speed information may be formed by measuring the flow velocity of the surrounding aerosol to obtain the flow velocity of the surrounding gas, and comparing the flow velocities at different positions to obtain the wind direction. The measuring unit can also measure the wind speed by a conventional cup anemometer, in which case the wind speed information only includes the magnitude data of the wind speed and not the wind direction data. Referring to fig. 3, if the high altitude wind speed is greater and the low altitude wind speed is less, the measuring device 30 in the high altitude will be blown farther away from the far point.
Since the measuring device 30 will be inclined to some extent when blown, the measuring device 30 is further provided with a balancing unit, and when the measuring device 30 is inclined, the balancing unit will maintain the measuring unit in a horizontal state, so that the wind speed measured by the measuring unit is still the wind speed in the horizontal direction. For example, when the measuring device 30 generates an inclination angle of 15 degrees, the motor of the balancing unit controls the measuring unit to rotate in the opposite direction by 15 degrees to compensate for the inclination angle of the measuring device 30. Or a balancing unit with the center of gravity below is arranged in the measuring device 30, and no matter how large the angle of the measuring device 30 inclines, the heavier balancing unit is vertically downward under the management of gravity, so that the measuring unit is driven to maintain the horizontal measuring direction.
Since the measuring unit directly measures the flow velocity of the measuring device 30 relative to the surrounding air, when the measuring device 30 is blown, the measured wind velocity data has errors due to the relative movement between the measuring device and the ground. And the wind speed information we need is the velocity of the ground relative to the air. Alternatively, to eliminate the error, two schemes are provided below to eliminate the error, making the measurement more accurate. In one embodiment, the movement speed of the measuring device 30 is calculated from the offset from the origin recorded in real time by the measuring unit, and the wind speed information directly measured by the measuring unit is compensated. Alternatively, an acceleration measuring unit is additionally provided in the measuring device 30, and the movement speed of the measuring device 30 is calculated using the measured acceleration information, thereby compensating for the wind speed information. After compensation is performed according to the movement speed of the measuring device 30, errors caused by movement of the measuring device 30 can be eliminated, and the wind speed measuring system can be fixed on a traveling ship to measure wind speeds of different places during navigation.
Further, the system further comprises a data recording device, and the wind speed information measured by the measuring device 30 can be transmitted to the data recording device in a wired or wireless mode. The data logging device is integrated with the fixture 10 and may also be integrated with the power unit 40. After the wind speed measuring system is arranged at the designated position and sufficient measuring information is collected, the lifting force of the power device 40 is reduced, the wind speed measuring system is recovered, and the measuring information is read from the data recording device. Specifically, if the measurement information is transmitted by wire, a cable may be provided in the connection device 20 so that the connection device 20 has a data transmission function and transmits the measurement information to a data recording device or other terminal. The measurement information may also be transmitted wirelessly, a wireless transceiver may be installed on the measurement device 30, and the measurement information measured by the measurement device 30 may be transmitted to a data recording device or other terminals via radio waves, and if the distance between the measurement devices 30 is long and the signal strength of the radio waves is insufficient, a relay unit may be installed on the measurement device 30 for receiving and forwarding the measurement information of other measurement devices.
Preferably, the wind speed measurement system can carry out anti-corrosion treatment on each device, avoids rapid aging and accuracy reduction of the system caused by seawater corrosion, and prolongs the service life.
It can be seen that the wind speed measuring system provided by the present application can be arranged at a given height through the power device 40, and measure wind speed information at different heights through the cooperative cooperation of the plurality of measuring devices 30.
When the system is not installed, the occupied space is small, and the transportation is simple and convenient. The connection of the connection device 20 to other devices can be designed to be detachable, so that when installation is required, the number of measuring devices 30 and the length of the connection device 20 can be assembled in a modular manner according to the requirements of specific engineering.
When the wind speed measurement system of this application was not installed, occupation space was less, and weight is also lighter, need not carry out the construction of base and truss like fixed anemometer tower. Taking a helium balloon as an example of the power device 40, the wind speed measurement system is transported to a designated sea area by a ship, and the rapid deployment of the wind speed measurement system can be completed only by arranging the fixing device 10 in the sea and filling gas into the helium balloon at the same time during installation. During recovery, the helium balloon is controlled to gradually release gas, the lift force is reduced, the power device 40, the connecting device 20 and the measuring device 30 fall from the air, and the wind speed measuring system can be quickly recovered from the sea surface for the next use. In addition, the system can be used for measuring the wind speed on land, and the complicated step of building a truss is avoided.
