Technical Field
The utility model belongs to the field of laser radars, and particularly relates to a protective device for an offshore laser radar.
Background
Lidar is a new type of environment detection equipment developed in recent years. Compared with the microwave radar, the laser radar has the advantages of high detection precision, small volume, good real-time performance and the like. However, the laser radar has a laser wave band as a light source, and is easily affected by weather environments such as rainwater, condensation, fog, and the like. Therefore, when designing the laser radar, the influence of surface water, rainwater, condensation and the like needs to be considered, and a wiper device is generally adopted to clean the optical window, but crystallized sea salt particles scratch the optical window.
Seawater has strong corrosiveness, and accumulated seawater can accelerate corrosion of equipment, so that maintenance cost and service life of the laser radar are further affected. In particular, a lidar installed on an island or buoy at sea is unattended for a long time, and the possibility that birds stay or nest on the lidar exists, which necessarily affects the normal use of the lidar.
Disclosure of Invention
The utility model aims to provide a protective device for an offshore laser radar, which aims to solve the technical problem that factors such as sea salt particles scratch an optical window, corrosion of piled sea water accelerating equipment, stay of seabirds and the like can influence normal use of the laser radar.
In order to achieve the above purpose, the specific technical scheme of the protection device for the offshore laser radar is as follows:
the utility model provides a protector for marine laser radar, is including preventing bird thorn 1, optical window 2 and integral type cylinder dustcoat 3, prevent bird thorn 1 setting at laser radar's top, the vertical cladding of integral type cylinder dustcoat 3 is in laser radar's outside, optical window 2 slope sets up in the top of integral type cylinder dustcoat 3, the bottom of integral type cylinder dustcoat 3 is provided with laser radar's external connector 4.
Further, the bird thorn 1 is made of 316 stainless steel.
Further, the integrated cylindrical housing 3 is mounted from top to bottom.
The protection device for the offshore laser radar has the following advantages: bird thorn, slope optical window and integrated form cylinder dustcoat design are prevented to satisfy the long-term unmanned on duty's of laser radar operation requirement under the marine environment, this protector possesses and avoids the sea water to pile up, the quick hydrophobic function of driving the seabird of surface ponding condensation, has realized the long-term reliable work's of laser radar in marine stormy environment target.

FIG. 1 is a schematic view of the structure of a protective device for an offshore laser radar according to the present utility model;
FIG. 2 is a schematic view of a bird spike preventing structure;
fig. 3 is a schematic structural view of an integrated cylindrical housing.
Detailed Description
For a better understanding of the objects, structures and functions of the present utility model, a protective device for an offshore lidar according to the present utility model will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-3, the protection device for the offshore laser radar comprises a bird spike preventing part 1, an optical window 2 and an integrated cylindrical outer cover 3, wherein the bird spike preventing part 1 is arranged at the top of the laser radar, the integrated cylindrical outer cover 3 is vertically coated outside the laser radar, the optical window 2 is obliquely arranged above the integrated cylindrical outer cover 3, and an external connector 4 of the laser radar is arranged at the bottom of the integrated cylindrical outer cover 3.
The protection device that this embodiment relates to has used three kinds of structural designs of bird thorn 1, inclined optical window 2 and integrative cylinder type dustcoat 3 to reach the purpose that reduces windward and drenching the rain cross-section, surface area water condensation is hydrophobic fast and drive the seabird, realize laser radar stable and reliable's work under the long-term unmanned on duty of offshore environment.
Bird thorn prevention design: aiming at the bird group in the area, the bird is traditionally driven by adopting a sound and illumination mode, so that birds are prevented from staying and nesting in the area. However, on unattended islands and buoys at sea, there is a potential for failure of sound and light equipment to repel seabirds. The design uses the anti-bird thorn 1 made of 316 stainless steel material, so that seabirds can be effectively prevented from staying. The bird thorn preventing design is simple and compact, and power supply is not needed; meanwhile, the bird thorns are integrated with the laser radar, so that the anti-bird thorns cannot be corroded when used in a marine environment for a long time.
Optical window tilt design of lidar: in the prior art, a wiper device is adopted to clean an optical window, and the mode has the condition that crystalline sea salt particles scratch the optical window to influence the performance of a laser radar; the wiper device is a moving part exposed outside the equipment, and can fail when used in a marine stormy environment. The optical window is simple in inclined structure form, and redundant exposed structures are avoided. Through experimental verification and structural layout, the inclination angle of the optical window 2 is theta, so that the surface water condensation can be quickly drained, the phenomenon of sea water accumulation can be avoided, and the device can be reliably used for a long time in a marine environment.
Design of integral type cylinder dustcoat: the lidar protection device of the present embodiment is provided with an integrated cylindrical housing. The exposed surface area of the integrated cylindrical outer cover 3 is the smallest under the condition of the same equipment core; the integrated cylindrical outer cover adopts a top-down installation mode, so that water flows down, and the accumulation of seawater is avoided; meanwhile, the sealing ring is convenient to install on the matching surface, so that the waterproof performance of the equipment is further improved; the external connector 4 of the laser radar is arranged below and arranged at the bottom of the laser radar, so that seawater accumulation can be effectively avoided.
The laser radar protection device provided by the utility model uses 3 structural designs: bird thorn prevention, inclined optical window and integrated cylindrical outer cover are designed to meet long-term unattended operation requirements of the laser radar in a marine environment. The protection device has the functions of avoiding sea water accumulation, quickly draining surface accumulated water and expelling seabirds, and achieves the aim that the laser radar works reliably in a marine stormy environment for a long time.
The protection device is integrated with the laser radar, so that the structure is compact and simple, and additional installation and matching are not needed; the protection device can ensure that the laser radar can be normally used in an offshore environment for a long time, the outer surface is not rusted, and the performance index of the laser radar is not reduced.
Although embodiments of the present utility model have been described in conjunction with the accompanying drawings, it will be apparent to those skilled in the art that several variations and modifications may be made without departing from the principles of the utility model, which are also considered to be within the scope of the utility model.
