[0039] like Figure 1 As shown, an embodiment of the present application provides a wind measuring radar 100, which relates to the technical field of laser detection equipment and is mainly used to measure wind direction and wind speed, and monitor the surrounding environment.
[0040] like Figures 1 to 3 As shown, the wind measurement radar 100 provided in this embodiment includes: a radar body 130 , a camera device 120 and a heating element 110 .
[0041] The radar body 130 defines a housing cavity 1311 and is provided with an opening 1321 communicating with the housing cavity 1311, and a lens 140 is provided at the opening 1321. The camera device 120 is provided in the housing cavity 1311 and is located at the opening 1321. The camera device 120 has a lens 121 disposed toward the lens 140. The heating element 110 is provided in the housing cavity 1311 and is provided along the outer peripheral side of the lens 140 and the outer peripheral side of the lens 121. The heating element 110 is used to heat the lens 140 and the lens 121.
[0042] Exemplarily, the heating element 110 may be a heating net, a ceramic heating sheet, a heating wire, an electric heating film, or other component that can convert electrical energy into thermal energy.
[0043] It should be mentioned that when the current wind measuring radar works in a humid environment or a low temperature environment, water molecules in the air easily condense on the surface of the lens and the lens surface of the camera device to form water mist, thereby affecting the wind measuring radar's monitoring of the surrounding environment.
[0044] In the wind measuring radar 100 provided in this embodiment, since the heating element 110 is added and the heating element 110 is arranged along the peripheral side of the lens 140 and the peripheral side of the lens 121, the heating element 110 can release heat at the peripheral side of the lens 140 and the peripheral side of the lens 121, thereby heating the lens 140 and the lens 121, which can effectively reduce the possibility of water molecules condensing on the lens 140 and the lens 121 to form water mist, thereby facilitating the wind measuring radar 100 to monitor the surrounding environment.
[0045] like Figure 8 As shown, in one embodiment, the heating element 110 is arranged in an arc shape along the outer peripheral side of the lens 140 and the outer peripheral side of the lens 121 .
[0046] In this embodiment, the arc-shaped heating element 110 can cover at least a portion of the outer peripheral side of the lens 140 and at least a portion of the outer peripheral side of the lens 121, so that the generated heat can be gathered on the lens 140 and the lens 121, reducing the dissipation of heat, thereby enhancing the heating effect on the lens 140 and the lens 121, and effectively improving the condensation of water mist on the lens 140 and the lens 121.
[0047] like Figure 7 As shown, further, the direction in which the camera device 120 points to the opening 1321 is defined as a preset direction x, and the side of the heating element 110 away from the camera device 120 is disposed beyond the lens 140 in the preset direction x.
[0048] In this embodiment, since the heating element 110 is arc-shaped and the side of the heating element 110 away from the camera device 120 exceeds the lens 140 in the preset direction x, the heating range of the heating element 110 can cover the space between the lens 140 and the external environment, thereby achieving a better heating effect on the lens 140 and the lens 121, and more effectively improving the condensation of water mist on the lens 140 and the lens 121.
[0049] In one embodiment, the projection area of the heating element 110 on the peripheral side of the lens 140 is S1, and the peripheral side area of the lens 140 is S2, satisfying: 1 / 4≤S1 / S2≤1; and / or the projection area of the heating element 110 on the peripheral side of the lens 121 is S3, and the peripheral side area of the lens 121 is S4, satisfying: 1 / 4≤S3 / S4≤1.
[0050] It should be noted that the projection area of the heating element 110 on the outer periphery of the lens 140 refers to the heating area of the heating element 110 on the outer periphery of the lens 140. The projection area of the heating element 110 on the outer periphery of the lens 121 refers to the heating area of the heating element 110 on the outer periphery of the lens 121.
[0051] Exemplarily, the following conditions are satisfied at the same time: 1 / 4≤S1 / S2≤1 and 1 / 4≤S3 / S4≤1. Of course, only one of 1 / 4≤S1 / S2≤1 and 1 / 4≤S3 / S4≤1 may be satisfied.
[0052] It can be understood that when S1 / S2=1 / 4, the heating area of the heating element 110 covers 25% of the outer peripheral area of the lens 140. When S1 / S2=1, the heating area of the heating element 110 covers 100% of the outer peripheral area of the lens 140, that is, the arc-shaped heating element 110 is arranged around the outer peripheral side of the lens 140. S3 / S4 is the same as the above description, and will not be repeated here.
[0053] In this embodiment, since the heating element 110 is in an arc shape and satisfies 1 / 4≤S1 / S2≤1 and / or 1 / 4≤S3 / S4≤1, that is, the heating area of the heating element 110 accounts for 25% to 100% of the peripheral side area of the lens 140 and / or the peripheral side area of the lens 121. In this way, the heat generated by the heating element 110 can be better concentrated on the lens 140 and the lens 121, reducing the dissipation of heat, thereby achieving a better heating effect on the lens 140 and the lens 121, thereby improving the condensation of water mist on the lens 140 and the lens 121.
[0054] In another embodiment, the heating element 110 is arranged in a plane along the outer peripheral side of the lens 140 and the outer peripheral side of the lens 121. The planar heating element 110 can also heat the lens 140 and the lens 121 to achieve the effect of reducing the generation of water mist. No specific limitation is made to the shape of the heating element 110 herein.
[0055] like Figure 3 and Figure 6 As shown, in one embodiment, the wind measurement radar 100 also includes a main board 150 arranged in the accommodating cavity 1311, the heating element 110 includes a heating part 111 and a conductive part 112, the heating part 111 is arranged along the outer peripheral side of the lens 140 and the outer peripheral side of the lens 121, one end of the conductive part 112 is electrically connected to the side of the heating part 111 away from the lens 140, and the end of the conductive part 112 away from the heating part 111 is electrically connected to the main board 150.
[0056] Exemplarily, the mainboard 150 may be a printed circuit board (PCB) or a flexible printed circuit board (FPC). It should be noted that the mainboard 150 is used to control the entire wind radar 100 and is used to be electrically connected to the internal battery of the wind radar 100 or to an external power supply device.
[0057] In this embodiment, since one end of the conductive portion 112 is electrically connected to the side of the heating portion 111 away from the lens 140, and the end of the conductive portion 112 away from the heating portion 111 is electrically connected to the main board 150, the main board 150 can supply power to the heating portion 111 through the conductive portion 112 and control the working mode of the entire heating element 110, such as adjusting the operating power of the heating element 110, controlling the heating element 110 to start heating, controlling the heating element 110 to stop heating, etc., so that the wind measurement radar 100 can monitor the surrounding environment in harsh environments such as humidity and low temperature.
[0058] like Figures 1 to 3 As shown, in one embodiment, the radar body 130 includes an outer shell portion 131 and a connecting portion 132 connected to each other, the camera device 120 is connected to the connecting portion 132, the outer shell portion 131 has a accommodating cavity 1311, the connecting portion 132 is provided with an opening 1321 passing through it, and is mounted on the outer peripheral side of the lens 140 and the outer peripheral side of the lens 121 through the opening 1321, and the heating element 110 is located on the outer peripheral side of the connecting portion 132.
[0059] In the present embodiment, since the connecting portion 132 is sleeved on the outer peripheral side of the lens 140 and the outer peripheral side of the lens 121 through the opening 1321 passing through the connecting portion 132, and the heating element 110 is located on the outer peripheral side of the connecting portion 132, that is, the heating element 110 is indirectly arranged on the outer peripheral side of the lens 140 and the outer peripheral side of the lens 121, the heating element 110 can heat the lens 140 and the lens 121 through the connecting portion 132, that is, the heat of the heating element 110 is first transferred to the connecting portion 132, and the connecting portion 132 then transfers the heat to the lens 140 and the lens 121, thereby heating the lens 140 and the lens 121 to improve the situation of condensation of water mist on the lens 140 and the lens 121.
[0060] like Figure 4 As shown, further, the heating element 110 is arranged in contact with the outer peripheral side of the connecting portion 132, that is, the heating element 110 is in contact with the outer peripheral side of the connecting portion 132, which can effectively reduce the dissipation of heat, so that the heat generated by the heating element 110 can be gathered on the connecting portion 132, thereby achieving a better heating effect on the lens 140 and the lens 121.
[0061] like Figures 2 to 4 As shown, further, the radar body 130 also includes an annular mounting portion 133, the annular mounting portion 133 is located in the opening 1321, and the outer peripheral side of the annular mounting portion 133 is connected to the connecting portion 132, the lens 140 is located on the side of the annular mounting portion 133 facing the camera device 120, and the edge of the lens 140 is attached to the annular mounting portion 133.
[0062] In this embodiment, since the annular mounting portion 133 is provided in the opening 1321, the lens 140 is located on the side of the annular mounting portion 133 facing the camera device 120, and the edge of the lens 140 is attached to the annular mounting portion 133, a sealing effect can be achieved, which increases the difficulty for water molecules in the external environment to enter the accommodating cavity 1311, thereby reducing the possibility of water molecules entering the accommodating cavity 1311 and condensing on the surface of the lens 121.
[0063] like Figures 3 to 5 As shown, further, the radar body 130 also includes an annular sealing portion 134, the camera device 120 includes a body 122, a mounting member 123 and a lens 121, the body 122 is connected to a side of the lens 121 away from the opening 1321, the mounting member 123 is connected to the body 122 and is arranged around the lens 121, and the annular sealing portion 134 is sleeved on the outer peripheral side of the lens 121 and abuts between the mounting member 123 and the connecting portion 132.
[0064] Exemplarily, the annular sealing portion 134 may be a silicone sealing ring, a rubber sealing ring, annular sealing foam or other element having an elastic sealing function.
[0065] In this embodiment, since an annular sealing portion 134 is added, the annular sealing portion 134 is sleeved on the outer peripheral side of the lens 121 and abuts between the mounting member 123 and the connecting portion 132. In this way, the gap between the mounting member 123 and the inner wall of the opening 1321 can be sealed, thereby increasing the difficulty for water molecules in the external environment to enter the accommodating cavity 1311, and can reduce the influence of water molecules on the electronic components inside the wind measuring radar 100, thereby reducing the failure rate of the wind measuring radar 100.
[0066] like Figure 4 As shown, further, an annular sealing groove 1322 is opened at one end of the connecting portion 132 close to the fuselage 122, a part of the annular sealing portion 134 is embedded in the annular sealing groove 1322, and a part of the annular sealing portion 134 away from the annular sealing groove 1322 abuts against the mounting member 123.
[0067] In the present embodiment, an annular sealing groove 1322 is provided at one end of the connection portion 132 close to the fuselage 122, a portion of the annular sealing portion 134 is embedded in the annular sealing groove 1322, and a portion of the annular sealing portion 134 away from the annular sealing groove 1322 abuts against the mounting member 123, thereby extending the sealing path (water molecules in the external environment need to pass through the groove wall of the annular sealing groove 1322 and the annular sealing portion 134 before entering the accommodating cavity 1311), thereby improving the sealing effect and being able to more effectively reduce the influence of water molecules on the electronic components inside the wind measurement radar 100.
[0068] Of course, for the above embodiment, an annular sealing groove 1322 may also be provided on the side of the mounting member 123 facing the lens 140 , which can also increase the sealing effect of the annular sealing portion 134 . No specific limitation is imposed on the location of the annular sealing groove 1322 .
[0069] In another embodiment, the heating element 110 may also be directly disposed on the peripheral side of the lens 140 and the peripheral side of the lens 121, that is, there are no obstructions between the heating element 110 and the peripheral side of the lens 140 and between the heating element 110 and the peripheral side of the lens 121, which can also achieve the heating effect on the lens 140 and the lens 121.
