DETAILED DESCRIPTION

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0059] Combination Figure 1-Figure 9 As shown, a vehicle type scanning and recognition device of the present invention comprises:

[0060] Column 1, with two identification components arranged on the top of column 1;

[0061] A protection seat 3 is fixed on the top of the column 1, and the protection seat 3 is a hollow structure;

[0062] A protective cover 2 is fixed to the bottom of the protective seat 3, and the identification component is arranged in the protective cover 2;

[0063] A transmission ring 15, the transmission ring 15 is rotatably arranged at the bottom of the protective cover 2, and two cleaning components are arranged on the top of the transmission ring 15;

[0064] A pneumatic assembly, which is arranged at the bottom of the protective cover 2 and is used to drive the transmission ring 15 to rotate. The pneumatic assembly is connected to the cleaning assembly;

[0065] An oil storage box 14, which is arranged on the inner wall of the bottom of the protective cover 2, and is filled with heat transfer oil;

[0066] A return pipe 12, which is fixed to the top of the oil storage box 14 and is connected to the bottom of the protective seat 3;

[0067] The oil supply pipe 13 is fixed to the top of the oil storage box 14, and the oil supply pipe 13 is connected to the top of the protective seat 3;

[0068] A heating component is arranged on the inner wall of the bottom of the oil storage box 14, and is used to heat the heat transfer oil;

[0069] The connecting component is connected with the pneumatic component and the oil storage box 14 , and the connecting component is used to input gas into the oil storage box 14 so that the heat transfer oil can enter the protective seat 3 .

[0070] As the working time of the device increases, floating dust will appear on the surface of the protective cover 2. At this time, the transmission ring 15 is driven to rotate by the pneumatic component, which in turn drives the cleaning component to rotate. When the cleaning component moves on the surface of the protective cover 2, the surface of the 2 is cleaned. In addition, when the pneumatic component is working, part of the gas enters the cleaning component, and the cleaning component is output to clean the floating dust in the form of airflow, thereby avoiding scratches on the surface of the protective cover 2, and also reducing the dust adhesion on the surface of the cleaning component, thereby ensuring the subsequent cleaning effect of the cleaning component.

[0071] Furthermore, it also includes:

[0072] A first solenoid valve 19, which is fixed on the top inner wall of the oil storage box 14, and is connected to the return pipe 12;

[0073] The exhaust valve 4 is fixed on the inner wall at the top of the protection seat 3 .

[0074] Further, the pneumatic assembly includes:

[0075] An annular seat 27, the annular seat 27 is fixed to the bottom of the protective cover 2, and an annular groove is formed on the side wall of the annular seat 27;

[0076] An annular plate 25, the annular plate 25 is rotatably disposed on the side wall of the annular seat 27;

[0077] A plurality of transmission plates 26, wherein the plurality of transmission plates 26 are fixed on the side wall of the annular plate 25 at equal distances, and each transmission plate 26 is fixed to the transmission ring 15;

[0078] A plurality of baffles 31 are fixed on the inner wall of the annular plate 25 at equal distances, and each baffle 31 is in the annular groove;

[0079] An air inlet nozzle 32, the air inlet nozzle 32 penetrates and is fixed on the inner wall of the annular seat 27;

[0080] The air pump box 5 is fixed on the side wall of the column 1. An air pump is arranged in the air pump box 5. An air supply pipe 28 is arranged at the output port of the air pump, and the air supply pipe 28 is communicated with the air inlet nozzle 32.

[0081] When the air pump is turned on, the air pump outputs gas through the air supply pipe 28 and the air inlet nozzle 32, pushing the baffle 31 to move, thereby causing the annular plate 25 to rotate around the annular seat 27, and then driving the transmission ring 15 to rotate through the transmission plate 26, so as to drive the brush plate 9 and the connecting seat 10 to move along the surface of the protective cover 2;

[0082] During this process, part of the gas in the annular seat 27 enters the connecting seat 10 through the connecting pipe 33, and then is output through the air nozzle 11 on the connecting seat 10 to blow away the floating dust on the surface of the protective cover 2 to achieve a cleaning effect on the surface of the protective cover 2, thereby ensuring the light transmittance of the protective cover 2, and further ensuring that the laser radar 7 and the camera 8 can work normally;

[0083] Another part of the gas enters the gas storage bottle 24 through the self-operated pressure regulating valve 22 and the first tube body 23. The gas is stored in a high-pressure form. When the gas pressure in the gas storage bottle 24 is too high, it is discharged through the pressure relief valve 34.

[0084] During the cleaning process, the brush plate 9 moves along the surface of the protective cover 2 to further clean the protective cover 2. Since the floating dust is blown away by the airflow, it is avoided that the brush plate 9 adheres to too much unnecessary dust, thereby ensuring the cleaning ability of the brush plate 9.

[0085] Further, the cleaning component includes:

[0086] A brush plate 9, which is fixed on the top of the transmission ring 15;

[0087] A connecting seat 10, the connecting seat 10 is fixed on the side wall of the brush plate 9, and a plurality of air nozzles 11 are fixed through the side wall of the connecting seat 10;

[0089] Furthermore, the pneumatic component also includes:

[0090] A gas cylinder 24, the gas cylinder 24 is fixed to the bottom of the annular seat 27, and a pressure relief valve 34 is provided through the bottom of the gas cylinder 24;

[0091] A self-operated pressure regulating valve 22, which is fixed through the bottom of the annular seat 27;

[0092] A first tube body 23, one end of the first tube body 23 is connected to the self-operated pressure regulating valve 22, and the other end of the first tube body 23 is connected to the gas storage bottle 24;

[0093] A second solenoid valve 29, which is fixed through the top of the gas storage bottle 24;

[0094] An air delivery pipe 21 is connected to the second solenoid valve 29, and the air delivery pipe 21 passes through the bottom inner wall of the oil storage box 14;

[0095] A plurality of circular holes 30 are provided at equal distances on the top of the side wall of the gas delivery pipe 21;

[0096] The cover body 20 is fixed on the top of the gas delivery pipe 21 .

[0097] Further, the heating component comprises:

[0098] A heating plate 18 is fixed to the inner wall of the bottom of the oil storage box 14, and a heating wire is embedded on the top of the heating plate 18;

[0099] The connecting plate 16 is fixed on the top of the heating plate 18 , and a plurality of fins 17 are arranged on the top of the connecting plate 16 .

[0100] In winter, there will be snow on the top of the protective seat 3. When the snow melts, icicles will condense at the edge of the protective seat 3, affecting the line of sight of the laser radar 7 and the camera 8. At this time, the switch of the heating wire needs to be turned on. When the heating wire works, it heats the thermal oil in the oil storage box 14 through the connecting plate 16 and the fin 17, and then the switch of the second solenoid valve 29 is turned on. The high-pressure gas in the gas cylinder 24 enters the oil storage box 14 through the second solenoid valve 29 and the gas pipe 21, and then pushes the thermal oil in the oil storage box 14 into the protective seat 3 through the oil supply pipe 13. At this time, keep the first solenoid valve 19 in a closed state, and the high-temperature thermal oil can melt the snow on the surface of the protective seat 3. Then turn on the switch of the first solenoid valve 19, so that the thermal oil in the lower part of the protective seat 3 can flow back to the oil storage box 14 through the reflux pipe 12, and the thermal oil is heated again by the heating wire.

[0101] Furthermore, the identification components include:

[0102] A fixing plate 6, the fixing plate 6 is fixed on the side wall of the column 1;

[0103] Two laser radars 7, the two laser radars 7 are fixed on two side walls of the fixing plate 6;

[0104] Camera 8 , which is fixed at the bottom of the fixing plate 6 .

[0105] The specific working principle of a vehicle type scanning and identification device of the present invention is as follows:

[0106] During the working process, the distance between the device and the vehicle is measured by two laser radars 7 on the fixed plate 6, and the vehicle picture is collected in cooperation with the camera 8. The appearance data of the vehicle is judged by the vehicle size in the picture and the distance between the device and the vehicle, and the vehicle recognition work is realized in cooperation with the vehicle picture;

[0107] As the working time of the device increases, floating dust will be present on the surface of the protective cover 2. At this time, the switch of the air pump is turned on. When the air pump works, the gas is output through the air supply pipe 28 and the air inlet nozzle 32, pushing the baffle 31 to move, thereby causing the annular plate 25 to rotate around the annular seat 27, and then driving the transmission ring 15 to rotate through the transmission plate 26, so as to drive the brush plate 9 and the connecting seat 10 to move along the surface of the protective cover 2;

[0108] During this process, part of the gas in the annular seat 27 enters the connecting seat 10 through the connecting pipe 33, and then is output through the air nozzle 11 on the connecting seat 10 to blow away the floating dust on the surface of the protective cover 2 to achieve a cleaning effect on the surface of the protective cover 2, thereby ensuring the light transmittance of the protective cover 2, and further ensuring that the laser radar 7 and the camera 8 can work normally;

[0109] Another part of the gas enters the gas storage bottle 24 through the self-operated pressure regulating valve 22 and the first tube body 23. The gas is stored in a high-pressure form. When the gas pressure in the gas storage bottle 24 is too high, it is discharged through the pressure relief valve 34.

[0110] During the cleaning process, the brush plate 9 moves along the surface of the protective cover 2 to further clean the protective cover 2. Since the floating dust is blown away by the airflow, it is avoided that the brush plate 9 adheres to too much unnecessary dust, so as to ensure the cleaning ability of the brush plate 9.

[0111] In winter, there will be snow on the top of the protective seat 3. When the snow melts, icicles will condense at the edge of the protective seat 3, affecting the sight lines of the laser radar 7 and the camera 8. At this time, the switch of the heating wire needs to be turned on. When the heating wire works, it heats the heat transfer oil in the oil storage box 14 through the connecting plate 16 and the fin 17. Then, the switch of the second solenoid valve 29 is turned on, and the high-pressure gas in the gas cylinder 24 enters the oil storage box 14 through the second solenoid valve 29 and the gas pipe 21, thereby pushing the heat transfer oil in the oil storage box 14 into the protective seat 3 through the oil supply pipe 13. At this time, the first solenoid valve 19 is kept in a closed state, and the high-temperature heat transfer oil can melt the snow on the surface of the protective seat 3. Then, the switch of the first solenoid valve 19 is turned on, so that the heat transfer oil in the lower part of the protective seat 3 can flow back to the oil storage box 14 through the reflux pipe 12, and the heat transfer oil is heated again by the heating wire.

[0112] During the reflux of the heat transfer oil, the gas in the oil storage box 14 enters the protection seat 3 through the oil supply pipe 13. When the air pressure in the protection seat 3 is high, the exhaust valve 4 is opened to exhaust the gas in the protection seat 3.
