Description

Technical Field

[0001] The invention relates to the technical field of optical radiation measuring devices, in particular to an automatic whiteboard flipping device for a ground radiometer measuring system. Background Art

[0002] Atmospheric environmental science and meteorological research, all-day ground truth collection technology systems, require stable and accurate measurement of key parameters of surface radiation characteristics under normal operating conditions; scientific research fields such as crop growth monitoring also require unattended automatic measurement of surface multi-spectral reflectance in the field, monitoring changes in ground spectral radiance and spectral reflectance. Therefore, the ground reflection spectrum measurement equipment used for measuring surface radiation characteristics must adapt to harsh environments such as sand, grass, rain, and hail in the field.

[0003] When measuring the surface radiation reflectivity, a diffuse reflective white board is needed as a standard reference board. The white board will be contaminated after being exposed to the air for a long time, which will affect the accuracy of the measurement data. Therefore, special protection is required for the white board to enter the white board cabin when it is not working.

[0004] When measuring on the ground, a whiteboard is needed as a reference board for calibration. Conventional whiteboard flipping structures have worm gears, gear transmission systems, and dual-axis drive arm power structures. The transmission structure is complex and the transmission noise is high. After long-term use, transmission clearance will occur, affecting the precise control of the transmission. Maintenance is troublesome. Outdoor adaptability is poor, the equipment is soaked in water and damp, the motor performance is reduced, and the transmission control fails. The whiteboard sealing details are not in place, and there will be pollution from air particles and floating sediments. Summary of the invention

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figures 1 to 8The present invention provides a technical solution: an automated whiteboard flipping device for a ground radiometer measurement system, comprising a vertical pole 1, a platform support frame 2 fixedly mounted on the vertical pole 1, a transmission assembly 8 fixedly mounted on the top of the platform support frame 2, the transmission assembly 8 is connected to a whiteboard cross arm assembly 6, a counterweight 5 is fixedly mounted on one end of the whiteboard cross arm assembly 6, and a whiteboard box assembly 7 is fixedly mounted on the other end; the transmission assembly 8 comprises a protective cover 81 fixedly mounted on the top of the platform support frame 2, a motor 82 fixedly mounted inside the protective cover 81, a reducer 84 is fixedly mounted on the end of the motor 82 through a motor flange 83, the output end of the motor 82 is fixedly connected to the input end of the reducer 84, a transmission sleeve seat 85 is fixedly mounted on the inner wall of the protective cover 81, and the reducer 84 is fixedly mounted on the transmission sleeve Inside the cylinder seat 85, the reducer 84 is connected to an output shaft 87, and the end face of the protective cover 81 is fixedly connected to a transmission seat 88. The transmission seat 88 is a centering structure of a boss and is embedded in the transmission sleeve seat 85. Such a structural design ensures the coaxiality of the output of the traditional system and ensures the smooth operation and reliability of the system. A rotating support bearing 86 is fixedly installed on the inner wall of the transmission seat 88, and the output shaft 87 is passed through the rotating support bearing 86 to improve the overload resistance and reliability. A rotating auxiliary support bearing is designed at the position of the rotating output shaft to improve the reliability and durability of the system. A bearing pressure cover 89 for limiting the rotating support bearing 86 is fixedly installed at the end of the transmission seat 88, and a load-bearing connecting plate 812 is fixedly installed at the end of the transmission seat 88.

[0031] A dynamic sealing element 811 is arranged at the rotation connection place between the load-bearing connection plate 812 and the transmission stand 88, and a double labyrinth structure is formed by the outer edge of the circumference of the load-bearing connection plate 812 and the transmission stand, forming a physical seal to prevent external dirt from invading the transmission system, avoid contamination of the sealing grease, and improve the service life of the sealing element and the reliability of the seal; a sealing groove is arranged between the protective cover 81 and the transmission stand 88, and a sealing element 813 is placed in the sealing groove, and a sealing ring 810 is arranged on the side of the load-bearing connection plate 812 close to the output shaft 87. The sealing element 813 can effectively prevent the intrusion of external liquids, ensuring the safety, reliability and normal operation of the internal system structure; this sealing method combining dynamic and static sealing forms a completely closed transmission system, improves the protection level of the system, and ensures the reliability of working in harsh outdoor environments.

[0032] The rotation angle of the whiteboard crossarm assembly 6 can be adjusted by the transmission assembly 8. When measuring, the whiteboard 72 inside the whiteboard box assembly 7 is moved to just below the optical lens 9. When not in working state, the whiteboard crossarm assembly 6 is driven to rotate again, so that the whiteboard 72 inside the whiteboard cover 71 is rotated to the sealed connection of the sealed bottom box 74, thereby realizing a closed and sealed state.

[0033] The whiteboard crossarm assembly 6 includes a crossbar 61, a right welded base plate 62 fixed to the end of the crossbar 61, and a right welded rib frame 63 fixed to the end of the right welded base plate 62. The end of the output shaft 87 is fixedly connected to a fixed angle frame 13, the top of the fixed angle frame 13 is fixedly connected to a left welded base plate 12, the left welded base plate 12 is fixedly connected to the crossbar 61, and a left welded rib frame 14 is fixedly connected between the crossbar 61 and the left welded base plate 12; the right welded base plate 62 serves to connect and maintain the regularity and flatness of the right welded rib frame 63, thereby ensuring the horizontality of the whiteboard 72 during installation.

[0034] The other end of the crossbar 61 is fixedly connected with a counterweight block 5 to achieve the purpose of counterweighting the whiteboard box assembly 7 and ensure its safe use in various environments.

[0035] The whiteboard box assembly 7 includes a whiteboard cover 71 fixed to the bottom of the right welding rib 63, and a whiteboard 72 fixed inside the whiteboard cover 71. A whiteboard box body support plate 75 is fixedly mounted on the vertical pole 1 through a second clamp 76. A sealed bottom box 74 is fixedly mounted on the top of the whiteboard box body support plate 75. A hollow elastic sealing ring 73 is fixedly connected to the top of the sealed bottom box 74. The supporting structure of this clamp type support plate is convenient for adjusting the relative center position of the optical lens 9 and the whiteboard 72 to ensure the basic measurement position parameter requirements of the system.

[0036] When in the non-working closed state, the driving cross bar 61 rotates, so that the whiteboard 72 inside the whiteboard cover 71 enters above the sealed bottom box 74. A hollow elastic sealing ring 73 is set on the top of the sealed bottom box 74. Under the action of the pre-tightening force, the hollow elastic sealing ring 73 fits tightly against the upper whiteboard frame. At this time, the sealed bottom box 74 forms a sealed space for the whiteboard 72, which has the functions of dust, sand and water prevention to avoid pollution.

[0037] A travel switch assembly 11 and an optical coupling switch assembly 10 are fixedly mounted on the transmission sleeve seat 85 .

[0038] The specific control process is that under the control of the control unit, when a whiteboard reference board is needed for reference measurement, the control system sends a command to start the motor 82 to rotate the whiteboard 72 to the working position. After the measurement is completed, the motor 82 is started again, and the whiteboard 72 moves to the closed state to achieve unattended operation.

[0039] The transmission system is automated, and a position sensor device provides an auxiliary feedback device to allow the system to stop accurately at the designed position. The specific composition is an optocoupler switch component 10; the trigger position of the optocoupler switch component 10 is also the working closed state position, at which time the motor 82 stops; at the same time, in order to ensure the reliability of the automation system device and reduce the damage to the structural device caused by the debugging personnel or the control program errors, a layer of protection device is added, namely the travel switch component 11, to prevent the damage to the mechanical device and instrument related components caused by the control error and overtravel; when the travel switch component 11 contacts the inner wall of the sealed bottom box 74, the motor 82 stops; the travel switch component 11 has high precision and compact size, which reduces the overall size of the transmission structure device.

[0040] An optical lens 9 is fixedly installed on the top of the vertical pole 1 through a supporting rod. The optical lens 9 is located above the whiteboard box assembly 7. The optical lens 9 is responsible for focusing the light to the entrance of the optical fiber and transmitting it to the measurement module unit through the optical fiber to complete the data collection and measurement.

[0041] The end of the platform support frame 2 is fixedly mounted with a mounting base 3, and the mounting base 3 is fixedly mounted on the vertical pole 1 through a first clamp 4, forming a stable structure that can withstand a certain load and provide the necessary stability and flexibility for the structure.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
