Detailed Description

For a better understanding of the nature of the present invention, its further description is provided below with reference to the following detailed description and the accompanying drawings.

The utility model discloses applicable to large-scale shallow lake, the structure of specific embodiment is as shown in figure 1 and figure 2, include: the waterproof shell 6 is a hollow cavity, and the waterproof shell 6 consists of an upper shell 7 and a lower shell 8. The upper shell 7 and the lower shell 8 are hollow hemispheroids with the same radius, and the waterproof shell 6 formed by the hemispheroids can reduce the resistance of water. The junction between the upper and lower casing is provided with first waterproof sealing ring 9, guarantees the waterproof nature of this device. An opening 10 is formed in the upper shell 7, a probe of the hot wire anemometer 3 penetrates through the opening 10 from the inside of the upper shell 7 and is exposed to the outside air, and the rest of the hot wire anemometer is positioned in the cavity of the waterproof shell 6. A second waterproof sealing ring 12 is arranged at the joint of the opening 10 and the probe of the hot-wire anemometer 3, so that water is prevented from entering the cavity. The waterproof casing 6 is made of polystyrene material, and is painted to be orange yellow, which is beneficial to observation and recovery.
