Description

TECHNICAL FIELD

[0001] The utility model relates to environment perception technical field especially relates to an environment perception device. BACKGROUND

[0002] Due to the complex and changeable sea conditions and wide field of vision, the perception device often needs to detect, observe and perceive the annular or larger fan-shaped field of vision through various cameras, and protect various cameras from corrosion by seawater through a firm and reliable shell. A single camera is subject to the principle of optical imaging, resulting in inevitable image distortion at the edge of the imaging field of view, and the larger the field of view, the more serious the image distortion. Therefore, two or more cameras are usually arranged at a certain angle to realize the detection, observation and perception of the annular or larger fan-shaped field of vision.

[0003] At present, in order to meet the needs of different marine environments and detection distances, for ships with limited space and unable to install multiple detection modules at the same time, the camera often needs to be adaptively replaced with lenses of different sizes. Due to the arrangement of the camera at a certain angle, the original bracket will not adapt to the new lens size under the limitation of the protective shell. The existing technology usually replaces the entire camera mounting bracket or even the entire camera detection module to adapt to the new lens size. This way not only reduces the universality and maintainability of the parts, but also increases the cost of the equipment and occupies valuable cabin storage space. On the other hand, the replacement steps are complex and time-consuming, and the adaptability to the changing sea conditions is poor. UTILITY MODEL CONTENT

By replacing replaceable isolation columns 202 of different specifications and lengths, the effect of adapting to lenses of different sizes, lengths, etc. can be quickly and simply achieved.

[0069] Specifically, the camera mounting support 201 is detachably and fixedly connected with the protective shell 1. The camera mounting support can be replaced when maintenance or other needs occur. Specifically, the replaceable isolation column 202 is a single-head isolation column; the number of replaceable isolation columns 202 used is 2-16; the replaceable single-head isolation column is a general standard part, which has various specifications and lengths, and generally functions to support and fasten a circuit board, insulate the circuit board, and ensure the height consistency of the circuit board.

[0070] When the lens is replaced, the overall structure of the newly replaced lens may be of different lengths, too long to be installed into the protective shell 1, or too short to be blocked by the protective shell 1, so that the effect of adapting to different lens sizes can be quickly and simply realized by replacing the single-head isolation column.

[0071] Embodiment 2

[0072] Embodiment 2 further installs a heat dissipation device on the basis of the technical solution of embodiment 1.

[0073] In the field of marine environment perception, the detection and perception equipment has high integration. For some equipment, various computing modules and laser radars inside are high heat generating devices. The equipment needs to be installed on the deck of a ship and needs to face the harsh marine environment such as high temperature and humidity and sunlight exposure. Therefore, it is necessary to design a suitable heat dissipation structure. The existing equipment or installs a heat dissipation structure for each part, which makes the structure complex and bulky and reduces reliability. Or the laser radar module is exposed, which loses the protection ability.

[0074] Specifically, as shown in Figure 1 and Figure 6 , as preferred, an environment perception device further comprises:

[0075] an upper inner cavity 103, the upper inner cavity 103 being arranged in the protective shell 1;

[0076] a laser radar 4, the laser radar 4 being connected with the protective shell 1;

[0077] a window 104, the window 104 being arranged in the protective shell 1 and being in communication with the upper inner cavity 103 and the outside;

[0078] an air flow channel 105, the air flow channel 105 being arranged between the laser radar 4 and the upper inner cavity 103 and being configured to allow gas to pass through;

[0079] an air outlet hole 106, the air outlet hole 106 being arranged in the protective shell 1 and being in communication with the upper inner cavity 103;

[0080] a heat dissipation fan 5, the heat dissipation fan 5 being connected with the protective shell 1, and the heat dissipation fan 5 being configured to suck air entering the upper inner cavity 103 into the air flow channel 105 and discharge the air from the air outlet hole 106.

[0081] as preferred, an environment perception device further comprises:

[0082] a heat dissipation fin 107, the heat dissipation fin 107 being arranged in the protective shell 1;

[0083] a heat dissipation cover plate 108, the heat dissipation cover plate 108 being connected with the heat dissipation fin 107, and the heat dissipation cover plate 108 being connected with the heat dissipation fan 5.

[0084] as preferred, an environment perception device further comprises:

[0085] a lower inner cavity, the lower inner cavity being arranged in the protective shell 1 and not being in communication with the upper inner cavity;

[0086] an operation module, the operation module being arranged in the lower inner cavity;

[0087] The heat-conducting block is arranged in the operation module and connected with the heat-dissipating fin 107. The operation module with large heat production is provided with the heat-conducting block, which is connected with the heat-dissipating fin 107, so that the heat dissipation of the operation module in the lower inner cavity is better achieved.

[0088] By inversely arranging the heat-dissipating fan on the heat-dissipating cover plate, the "air suction" and "air blowing" parts have heat-dissipating effect on the equipment in a compact structure.

[0089] For the embodiment, the upper inner cavity 103 is arranged on the protective shell 1, the window 104 connecting the upper inner cavity 103 with the outside is arranged on the protective shell 1, the laser radar 4 is arranged in the upper inner cavity 103, the laser radar 4 can detect the outside environment through the window 104, the airflow channel 105 is arranged between the upper inner cavity 103 and the laser radar 4, the protective shell 1 comprises the upper cover plate which can make the upper inner cavity 103 relatively closed, the heat-dissipating fin 107 is arranged on the protective shell 1, the airflow hole connecting the upper inner cavity 103 with the outside is arranged on the heat-dissipating fin 107, the heat-dissipating cover plate 108 is arranged on the heat-dissipating fin 107, and the heat-dissipating fan 5 is arranged on the heat-dissipating cover plate 108.

[0090] The surface of the heat-dissipating fan 5 close to the heat-dissipating fin 107 is the air inlet surface, and the surface close to the heat-dissipating cover plate 108 is the air outlet surface.

[0091] When the heat-dissipating fan 5 is powered on, the outside air is sucked into the upper inner cavity 103 through the window 104, and then the heat on the surface of the laser radar 4 is taken away through the airflow channel 105 (at this time, the upper inner cavity 103 forms a one-way channel under the action of the upper cover plate, that is, the window 104 is the inlet, and the air outlet hole 106 is the outlet), and finally the air is blown to the heat-dissipating fin 107 and the heat-dissipating cover plate 108 by the heat-dissipating fan 5 through the air outlet hole 106, and the heat of each component is taken to the outside environment.

[0092] In this process, as the heat generated by the start of the heat dissipation fan and the operation of the laser radar spreads to the surface of its shell, the cooler air outside first passes through the surface of the laser radar to take away the heat generated by it, and then through the upper inner cavity, the air outlet hole to take away the heat conducted to the heat dissipation fins and the heat dissipation cover plate by the heat conduction block of the operation module inside the device. In this way, the heat dissipation of the two larger heat sources inside and outside the device can be completed in a relatively compact structure with only one heat dissipation fan. The stability and reliability of the device are greatly improved, the overall size of the device is reduced, and the production and maintenance costs of the device are reduced. And because the laser radar, the heat dissipation fan and the related wire harness are arranged inside the device, they are protected by a solid shell, enhancing the overall protection capability. The use of the heat dissipation cover plate provides structural support for the installation of the heat dissipation fan, and also provides reliable protection for the heat dissipation fan and the heat dissipation fins, reducing the probability of foreign matter blocking the heat dissipation fins and the heat dissipation fan, while avoiding the temperature influence of the heat dissipation fins being exposed to the sun at sea, ensuring the stability and reliability of the overall structure heat dissipation capability.

[0093] Because the ship needs to face the high-temperature marine environment of solar exposure when it goes to sea, and some marine environment sensing devices cannot be provided with all-around and large-area sun-shielding and protection because they need to use cameras, laser radars and other devices to detect the external environment. Therefore, the device itself has good heat dissipation capability, which is very beneficial to improve the stability and reliability of the device, and the relatively small overall size also reduces the influence of solar exposure on the temperature of the device. In addition, the design can also improve the air flow efficiency of the laser radar and the chamber, remove excess moisture, reduce the risk of marine corrosion, and ensure the stability of the working environment of the laser radar. Further, the heat dissipation fins in the form of waves can be opened on the heat dissipation cover plate. In some war confrontation environment, the heat dissipation area is increased, the overall heat dissipation effect of the device is strengthened, the radar cross section is reduced, and the possibility of being detected and found by the opposing party radar is reduced. Further, the fan can be replaced with a cross-flow type to enhance the heat dissipation effect.

[0094] Obviously, the above embodiments are only examples for the sake of clarity, and are not limiting of the embodiments. Based on the above description, those skilled in the art can make other different forms of changes or variations. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
