[0036] As Figure 1As shown, in a first aspect, an embodiment of the present application provides a wind measurement radar 100, which relates to the technical field of laser detection devices and is mainly applied to devices with detection functions for measuring wind direction and wind speed.
[0037] As Figures 2 to 4 shown, the wind measurement radar 100 provided in this embodiment includes: a radar body 110 and a hot air device 120.
[0038] Among them, the radar body 110 defines a receiving cavity 1111. The hot air device 120 is located in the receiving cavity 1111, is connected to the radar body 110, and the hot air device 120 has an air inlet side 121 and an air outlet side 122.
[0039] When the current temperature of the air flow in the receiving cavity 1111 is less than the preset temperature, the hot air device 120 can suck the air flow in the receiving cavity 1111 from the air inlet side 121, heat the air flow and blow it out from the air outlet side 122 into the receiving cavity 1111 to realize circulating heating of the air flow in the receiving cavity 1111.
[0040] Exemplarily, the hot air device 120 selects a PTC (Positive Temperature Coefficient) heating fan, which can suck the air flow and blow out the air flow after constant temperature heating. In terms of safety, the PTC heating fan does not turn red or produce open flames when heating, so it has higher use safety.
[0041] Of course, the hot air device 120 can also be a combination of a blower and a heating element. The heating element is, for example, an electric heating tube, an electric heating wire, etc. The blower can suck and blow out the air flow, and the heating element can heat the sucked air flow.
[0042] It should be mentioned that when the wind measurement radar works in a low-temperature environment, the performance and service life of the electronic components inside the wind measurement radar will be affected by the low-temperature environment, thus affecting the detection accuracy of the wind measurement radar.
[0043] It can be understood that when using the wind measurement radar 100 provided in this embodiment, when the current temperature of the air flow in the receiving cavity 1111 is less than the preset temperature, the hot air device 120 can suck the air flow in the receiving cavity 1111 from the air inlet side 121, heat the air flow and blow it out from the air outlet side 122 into the receiving cavity 1111 to realize circulating heating of the air flow in the receiving cavity 1111, so as to maintain the stability of the internal environment temperature and improve the detection accuracy of the wind measurement radar 100 in a low-temperature environment.
[0044] As Figure 3 and Figure 4As shown, in one embodiment, the wind measurement radar 100 further includes a temperature sensor 130. The temperature sensor 130 is located in the accommodation cavity 1111 and is connected to the radar body 110. The temperature sensor 130 is used to detect the current temperature of the air flow in the accommodation cavity 1111.
[0045] In this embodiment, since the temperature sensor 130 is located in the accommodation cavity 1111 and is connected to the radar body 110, it is used to detect the current temperature of the air flow in the accommodation cavity 1111, so that the hot air device 120 can heat the internal environment of the wind measurement radar 100 in a timely manner in a low-temperature environment.
[0046] Exemplarily, the temperature sensor 130 is a thermistor, such as a positive temperature coefficient thermistor (PTC) or a negative temperature coefficient thermistor (NTC).
[0047] It can be understood that the thermistor has high sensitivity and can accurately and timely detect the current temperature of the air flow in the accommodation cavity 1111, thereby reducing the impact on the detection accuracy of the wind measurement radar 100 in a low-temperature environment due to untimely and inaccurate temperature detection.
[0048] As Figure 3 and Figure 4 shown, further, the wind measurement radar 100 further includes a control main board 140. The control main board 140 is located in the accommodation cavity 1111 and is connected to the radar body 110. The temperature sensor 130 and the hot air device 120 are respectively electrically connected to the control main board 140.
[0049] When the current temperature detected by the temperature sensor 130 is less than the preset temperature, the control main board 140 controls the hot air device 120 to heat the air flow in the accommodation cavity 1111; when the current temperature detected by the temperature sensor 130 is greater than or equal to the preset temperature, the control main board 140 controls the hot air device 120 to stop heating the air flow in the accommodation cavity 1111.
[0050] Exemplarily, the control main board 140 can be a printed circuit board (PCB) or a flexible printed circuit board (FPC).
[0051] In this embodiment, through the setting of the control main board 140 and electrically connecting the temperature sensor 130 and the hot air device 120 to the control main board 140 respectively, automatic control of the hot air device 120 can be achieved.
[0052] Specifically, by controlling the main board 140, the current temperature detected by the temperature sensor 130 can be obtained, and the current temperature is compared with a preset temperature, that is, it is determined whether the current temperature is greater than or equal to the preset temperature. If not, the hot air device 120 is controlled to heat the air flow in the accommodation cavity 1111 so that the current temperature of the air flow is maintained above the preset temperature. If so, the hot air device 120 is controlled to stop heating the air flow in the accommodation cavity 1111.
[0053] In one embodiment, a plurality of hot air devices 120 are provided. Adjacent hot air devices 120 are arranged at intervals. The plurality of hot air devices 120 are located on the same side of the accommodation cavity 1111, and the air outlet sides 122 of the plurality of hot air devices 120 face the same direction.
[0054] Exemplarily, the number of the hot air devices 120 can be selected as two, three, four, five, etc. Specifically, it can be set according to the internal space size of the wind measurement radar 100 and according to design requirements. No specific limitation is made on the number of the hot air devices 120 here.
[0055] In this embodiment, by arranging a plurality of hot air devices 120 at intervals in the accommodation cavity 1111, the heating efficiency of the air flow in the accommodation cavity 1111 can be improved, so that the temperature of the air flow can be quickly raised above the preset temperature.
[0056] At the same time, since the air outlet sides 122 of the plurality of hot air devices 120 face the same direction, the plurality of hot air devices 120 can respectively blow out the heated air flow towards the same side, which can reduce the possibility of interference between the air flows blown out by different hot air devices 120, thereby further improving the heating efficiency of the air flow in the accommodation cavity 1111.
[0057] As Figure 3 and Figure 4 shown, in one embodiment, the radar body 110 includes a housing 111, a first mounting member 112 and a second mounting member 113.

[0059] Exemplarily, the first mounting member 112 can be a mounting plate or a mounting bracket. No specific limitation is made on the structure of the first mounting member 112 here.
[0060] It should be noted that the above-mentioned “the hot air device 120 is fixed to the second mounting member 113 ” means that the hot air device 120 is fixedly connected to the second mounting member 113 , that is, the two will not move relative to each other.
[0061] In this embodiment, the provision of the first mounting member 112 and the second mounting member 113 facilitates the installation of the hot air device 120, so that the hot air device 120 can be away from the cavity wall position of the accommodating cavity 1111, so that the hot air device 120 can have a better heating effect and higher heating efficiency on the airflow in the accommodating cavity 1111.
[0062] It should be noted that when the wind measuring radar 100 is configured with the temperature sensor 130 mentioned above, the temperature sensor 130 can be installed on the first mounting member 112 , that is, the provision of the first mounting member 112 also facilitates the installation of the temperature sensor 130 .
[0063] like Figure 5 As shown, further, the second mounting member 113 is an air inlet plate, and the air inlet plate is provided with an air inlet 11311 passing through it. The hot air device 120 has an air inlet side 121 whose one end is fixed to the air inlet plate, and the air inlet 11311 is arranged opposite to the air inlet side 121 .
[0064] It should be noted that the above-mentioned “the hot air device 120 has one end of the air inlet side 121 fixed to the air inlet plate” means that: the end of the hot air device 120 where the air inlet side 121 is located is fixedly connected to the air inlet plate, and the two cannot move relative to each other.
[0065] In this embodiment, by setting the air inlet 11311 on the air inlet plate, the hot air device 120 can absorb the airflow in the accommodating cavity 1111 through its air inlet side 121, and blow the airflow out from the side away from the air inlet plate, that is, the air outlet side 122 after heating, so as to realize circulating heating of the airflow in the accommodating cavity 1111.
[0066] like Figure 5 As shown, further, the air inlet plate includes a plate portion 1131 and a connecting portion 1132, the connecting portion 1132 is connected to the first mounting member 112, one side of the plate portion 1131 is connected to the connecting portion 1132, and the plate portion 1131 is provided with an air inlet 11311 passing through it, and the hot air device 120 has an air inlet side 121 at one end fixed to the plate portion 1131.
[0067] It should be noted that the above-mentioned “the hot air device 120 has one end of the air inlet side 121 fixed to the plate portion 1131” means that: the end of the hot air device 120 where the air inlet side 121 is located is fixedly connected to the plate portion 1131, and the two cannot move relative to each other.
[0068] In this embodiment, through the setting of the connecting portion 1132, it is convenient to install the air inlet plate on the first mounting member 112. In addition, through the setting of the plate portion 1131 provided with the air inlet 11311, it is convenient for the hot air device 120 to suck the air flow in the accommodation cavity 1111 through its air inlet side 121.
