Description
Technical Field
The utility model relates to the technical field of offshore wind power generation, in particular to a floating body for installing an offshore wind measuring radar.
Background
The offshore wind contains inexhaustible wind resources, and the offshore wind has the advantages of small turbulence and small shear and is very beneficial to the installation of the wind generating set, but before the wind generating set is installed, wind resource measurement for at least one year needs to be carried out, including the measurement of wind speed, wind direction, turbulence and shear, so as to judge whether a certain sea area is suitable for the installation of the wind generating set and what type of wind generating set is installed. In the prior art, a wind measuring tower is needed for wind resource measurement, but the cost for installing the wind measuring tower at sea is too high, and the wind measuring tower is basically impossible to install at deep sea, therefore, the wind resource measurement at the deep sea area is generally measured by adopting a laser radar.
The method in the prior art is to design a circular floating body, install a laser radar on a bracket on the floating body, transport or tow the floating body to a designated sea area by a ship, then lower a sinking block and an anchor chain, float the laser radar around along with the floating body, and measure the wind resource of the designated sea area. In the process of measuring the wind speed and the wind direction, the laser radar is generally required to be in a static state, and if the laser radar is in a moving state, the internal algorithm of the laser radar needs to be corrected by means of the inclination angle, so that the sensor is required to assist in measuring the moving attitude in the process of moving the laser radar on the floating body with multiple degrees of freedom, and the wind speed value measured by the laser radar is continuously corrected through the moving attitude value.
The prior art scheme has the following defects:
1. the circular floating body is greatly influenced by wind wave flow, namely small wind waves can cause the floating body to move to a larger extent, and the larger the movement amplitude is, the more inaccurate the value of the laser radar corrected through the movement posture is;
2. the circular floating body is greatly influenced by wind, wave and flow, namely the circular floating body is stressed greatly, so that the size and the weight of the anchor chain are required to be large, and the cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provides a safe and reliable floating body for mounting an offshore wind measuring radar.
In order to achieve the purpose, the technical scheme provided by the utility model is as follows: the floating body is in a catamaran-shaped structure and consists of two independent ship-shaped floating body units and a deck, an anchor chain, a radar support and a posture sensor are configured, the two ship-shaped floating body units are connected into a whole through the deck, the upper end of the anchor chain is connected to the bottom of the deck, the lower end of the anchor chain is connected with a sinking block and then sinks to the seabed, the radar support is mounted on the deck, the posture sensor and the wind measuring radar are respectively mounted on the radar support, and the posture sensor feeds measured posture values back to the wind measuring radar to correct actually measured wind speed and wind direction values.
Further, the ship-shaped floating body unit is composed of a plurality of small floating bodies.
Further, the wind measuring radar is a laser radar.
Compared with the prior art, the utility model has the following advantages and beneficial effects:
1. the floating body of the catamaran-shaped structure is like a catamaran, the front end is small, and the middle part is hollow, so that the orientation of the floating body is always consistent with the direction of wind or water flow, more large-amplitude movements in other directions cannot be generated, the floating body is more stable, and the wind speed value corrected by the laser radar through the movement posture is more accurate;
2. the floating body of the catamaran-shaped structure is less affected by wind, wave and flow, so that the size and the weight of the anchor chain can be smaller than those of a round floating body with the same size, and the cost is saved.
3. Each ship-shaped floating body unit consists of a plurality of independent small floating bodies, and when any small floating body is damaged to cause water inflow, other small floating bodies are not influenced, so that the reliability is ensured.

Detailed Description
The present invention will be described in further detail with reference to examples and drawings, but the present invention is not limited thereto.
As shown in fig. 1 to 4, the floating body for installing the marine wind radar provided by the present embodiment is a catamaran-shaped structure, and is composed of two independent boat-shaped floating body units 1 and a deck 3, and is configured with an anchor chain 4, a radar bracket 6 and an attitude sensor 7; the ship-shaped floating body unit 1 consists of a plurality of small floating bodies 101, when any small floating body 101 is damaged to cause water inflow, other small floating bodies 101 are not influenced, and reliability is ensured; the two ship-shaped floating body units 1 are connected into a whole through the deck 3, and the deck 3 plays a role in connection and support; the upper end of an anchor chain 4 is connected to the bottom of the deck 3, and the lower end of the anchor chain 4 is connected with a sinking block 5 and then sinks to the seabed; a radar support 6 is fixed at the middle position of a deck 3, a laser radar 2 is installed on the radar support 6, an attitude sensor 7 is installed on the radar support 6, in the multi-freedom-degree movement process, the attitude numerical value measured by the attitude sensor 7 is fed back to the laser radar 2, and the laser radar 2 corrects the actually-measured wind speed and wind direction value according to the attitude numerical value, so that the measuring result is more accurate.
Under the combined action of wind, wave and current, because the floating body is of a catamaran-shaped structure, the front end is small, and the middle part is hollow, the orientation of the floating body is always consistent with the direction of wind or water flow, so that more large-amplitude motions in other directions cannot be generated, the floating body is more stable, and the wind speed value corrected by the laser radar through the motion attitude is more accurate; in addition, the floating body of the catamaran-shaped structure is less affected by wind, wave and flow, so that the size and the weight of the anchor chain can be smaller than those of a round floating body with the same size, and the cost is saved.
