Description

Technical Field

[0001] The present disclosure relates to the technical field of humidity sensors, and in particular to an external temperature and humidity sensor device for an all-sky imager. Background Art

[0002] An all-sky imager is an instrument used to observe and record cloud cover and cloud height in the sky. It is usually used in fields such as meteorological observation, astronomical research, and environmental monitoring. An all-sky imager is usually used in outdoor environments, and the scenario used is cloud map observation in the meteorological field. An all-sky imager requires external temperature and humidity data as a data source. Therefore, an all-sky imager usually needs to be equipped with a temperature and humidity sensor. The temperature and humidity sensor can monitor the ambient temperature and humidity in real time, providing strong support for equipment maintenance and environmental optimization. The temperature and humidity sensor uses thermal elements such as thermistors and thermocouples. The resistance or electromotive force of these elements will change with changes in temperature, thereby obtaining a temperature value; the temperature and humidity sensor uses humidity-sensitive elements such as lithium chloride and ceramics. The resistance or capacitance of these elements will change with changes in humidity, thereby obtaining a relative humidity value.

[0003] However, the prior art has the following problems:

[0004] 1. Most existing all-sky imagers place temperature and humidity sensors inside the instrument. Since the temperature and humidity sensors are not in contact with the outside air, the temperature and humidity data collected by the temperature and humidity sensors are less representative of the external atmospheric temperature and humidity environment.

[0005] 2. When the temperature and humidity sensor is installed on the outside of the all-sky imager, since the temperature and humidity sensor is usually fixed, after rainfall, due to local water accumulation on the ground, when the temperature and humidity sensor is close to the water accumulation location, due to the large amount of water evaporated at the water accumulation location, the humidity collected by the temperature and humidity sensor above the location is slightly greater than the actual value, thus affecting the accuracy of the data.

[0006] 3. On sunny days, the sun continuously shines on the temperature and humidity sensor, causing the temperature of the temperature and humidity sensor itself to rise, so that the temperature collected by the temperature and humidity sensor is slightly greater than the actual value, affecting the accuracy of the data.

[0040] Further, see Figure 8-Figure 11, a cleaning assembly 9 is used to maintain the cleanliness of the surface of the sensor probe 6. The cleaning assembly 9 includes two No. 2 slide bars 92, both of which are slidably mounted on the inner wall of the mounting cover 4, and the two No. 2 slide bars 92 are respectively located above the two No. 1 slide bars 85. Connecting rods 91 are respectively connected between the two No. 2 slide bars 92 and the two No. 1 slide bars 85. A slide rack 93 is connected between the two No. 2 slide bars 92, and the slide rack 93 is slidably connected to the bottom of the sunshade 5. A rotating seat 94 is rotatably mounted at the bottom of the slide rack 93, and a cleaning ring 95 is mounted on the rotating seat 94. Flexible bristles are arranged on the cleaning ring 95, and the flexible bristles of the cleaning ring 95 contact with the sensor probe 6 during the movement. The two No. 2 slide bars 92 are respectively connected to the two No. 1 slide bars 85. A connecting rod 91 is respectively connected between the two No. 2 slide bars 92. A slide rack 93 is connected to the bottom of the sunshade 5. A rotating seat 94 is rotatably mounted at the bottom of the slide rack 93, and a cleaning ring 95 is mounted on the rotating seat 94. Flexible bristles are arranged on the cleaning ring 95, and the flexible bristles of the cleaning ring 95 contact with the sensor probe 6 during the movement. When the rod 92 moves, it drives the slide 93 to move synchronously, and when the slide 93 moves, it drives the rotating seat 94 to move synchronously. When the rotating seat 94 moves to the left, the flexible bristles of the cleaning ring 95 on the rotating seat 94 can contact the sensor probe 6. The bottom of the sunshade 5 is connected to a ball ring frame 97, and the end of the rotating seat 94 away from the cleaning ring 95 is connected to a screw rod 96, and the ball ring frame 97 is sleeved on the screw rod 96. The inner wall of the ball ring frame 97 is provided with a ball and a threaded groove of the screw rod 96 for sliding connection. The screw 96 moves synchronously with the rotating seat 94. When the screw 96 moves, the ball in the ball ring frame 97 presses against the threaded groove of the screw rod 96, and the threaded groove rotates due to the reverse thrust of the ball when moving, so that The screw 96 can rotate when it moves, and the cleaning ring 95 is driven to rotate through the rotating seat 94 when the screw 96 rotates, so that the cleaning ring 95 can also rotate when it moves back and forth left and right. When the flexible bristles on the cleaning ring 95 come into contact with the sensor probe 6, the surface of the sensor probe 6 is cleaned by rotation, so as to avoid dust adhering to the surface of the sensor probe 6 and affecting the measurement accuracy; a spring piece 98 is installed on the slide 93 through a bracket, and the cleaning ring 95 is elastically arranged. The cleaning ring 95 comes into contact with the spring piece 98 during the movement.

The dust attached to the bristles is removed, thereby maintaining the cleanliness of the cleaning ring 95 itself; through the setting of the cleaning component 9, the cleaning ring 95 can rotate during the left and right reciprocating movement. After the flexible bristles on the cleaning ring 95 come into contact with the sensor probe 6, the flexible bristles clean the sensor probe 6 by rotating, thereby maintaining the cleanliness of the sensor probe 6, thereby maintaining the measurement accuracy of the sensor probe 6 and avoiding the dust attached to the surface of the sensor probe 6 and affecting the measurement accuracy; through the setting of the shrapnel 98, after the shrapnel 98 comes into contact with the cleaning ring 95, the cleaning ring 95 can vibrate, thereby shaking off the dust attached to the flexible bristles, thereby avoiding too much dust attached to the flexible bristles and affecting the cleaning effect.

[0041] With the above structure, the working principle of the present invention is that an annular groove is provided at the top and the bottom of the mounting ring 2, respectively, and the mounting seat 3 is slidably mounted on the two annular grooves, so that the mounting seat 3 can rotate on the mounting ring 2, and the sunshade 5 can block the sensor probe 6 to prevent the direct sunlight from shining on the sensor probe 6. Since the imager body 1 is usually installed at a high place, and there is usually wind at a high place, when the wind blows, the wind blows the three wind wheel blades 73, so that the three wind wheel blades 73 drive the upper shaft 71 to rotate through the three round rods 72, and the reduction gear box 76 is provided with a planetary reduction gear set, which can convert the input The speed of the upper shaft 71 is reduced and then output through the output end, which can achieve the effect of reducing the speed and increasing the torque. When the upper shaft 71 rotates, the lower shaft 77 is driven to rotate through the reduction gear box 76. When the lower shaft 77 rotates, it drives the driving gear 78 to rotate. When the driving gear 78 rotates, due to the meshing action with the gear ring 21, the driving gear 78 rolls on the outer wall of the gear ring 21. The driving gear 78 applies a reverse thrust to the mounting seat 3 through the lower shaft 77, so that the mounting seat 3 slides along the annular groove on the mounting ring 2, thereby achieving the effect that the mounting seat 3 can revolve around the imager body 1; the wind wheel blades 73 When rotating, the reflective lens 74 inside it can reflect light, so that the three wind wheel blades 73 can continuously reflect sunlight when rotating, so that nearby birds are irradiated by the reflected light and stay away from the sunshade 5, thereby achieving the effect of driving away birds. The three bird-driving rods 75 can rotate with the three round rods 72, and the bird-driving rods 75 can shake when rotating, further promoting the bird-driving effect. Through the setting of the sunshade 5, the sunshade 5 can protect the sensor probe 6 and block sunlight for the sensor probe 6, so as to avoid direct sunlight on the sensor probe 6 and affect the temperature measurement accuracy. Through the revolution component 7, the setting enables the mounting seat 3 to utilize wind force to rotate on the mounting ring 2, so that the sensor probe 6 on the mounting seat 3 continuously moves its position, so that the sensor probe 6 is in uniform contact with the air around the imager body 1, thereby improving the accuracy of temperature and humidity measurement, and avoiding the influence of temperature and humidity measurement data on the uneven temperature and humidity in the local position; through the cooperation of the reflective lens 74 and the bird-repelling rod 75, the reflective lens 74 can reflect light to illuminate the eyes of nearby birds, and the bird-repelling rod 75 can disperse nearby birds by rotating and shaking, thereby achieving the effect of bird repelling and avoiding the damage of the sensor probe 6 by birds.

[0042] The ball slider 82 can only slide up and down. When the lower shaft 77 rotates, the cooperation between the reciprocating thread groove 81 and the ball drives the ball slider 82 to slide up and down in the mounting cover 4. When the ball slider 82 slides up and down, it drives the two connecting seats 83 to move up and down. The two No. 1 slide bars 85 can only slide left and right. When the two connecting seats 83 move up and down, the two connecting rods 84 drive the two No. 1 slide bars 85 to move left and right. The two No. 1 slide bars 85 drive the two sets of triangular blocks 86 to move left and right. The two sets of triangular blocks 86 contact with the two paddles 89 when moving. When the triangular blocks 86 contact with the paddles 89, they will move the paddles 89 in the direction of their own movement. By turning the lever, the paddle 89 drives the fan plate 88 to rotate around the mounting shaft 87, and the counterweight rod 810 can drive the fan plate 88 to reset due to the action of gravity, thereby achieving the effect of the fan plate 88 being able to swing back and forth. The fan plate 88 can fan the air under the sunshade 5 by swinging back and forth, thereby promoting the air flow under the sunshade 5, and preventing the temperature under the sunshade 5 from increasing after being exposed to sunlight for a long time, thereby affecting the temperature measurement accuracy; through the setting of the spoiler component 8, the fan plate 88 can fan the air under the sunshade 5 by swinging back and forth, and fan out the heat generated by the sunlight, thereby preventing the accumulation of heat around the sensor probe 6 and affecting the measurement accuracy of the sensor probe 6.

[0043] When the two No. 1 slide bars 85 move, the two No. 2 slide bars 92 are driven to move back and forth left and right through the two connecting rods 91. When the two No. 2 slide bars 92 move, they drive the slide 93 to move synchronously. When the slide 93 moves, it drives the rotating seat 94 to move synchronously. During the movement of the rotating seat 94 to the left, the flexible bristles of the cleaning ring 95 on the rotating seat 94 can contact the sensor probe 6. While the rotating seat 94 moves, the screw 96 moves synchronously with the rotating seat 94. When the screw 96 moves, the balls in the ball ring frame 97 resist the thread groove of the screw 96. The thread groove rotates under the reverse thrust of the balls when moving, so that the screw 96 can rotate when moving. When the screw 96 rotates, the cleaning ring 95 is driven to rotate through the rotating seat 94, so that the cleaning ring 95 can also rotate when it reciprocates left and right. When the flexible bristles on the cleaning ring 95 contact the sensor probe 6, they clean the surface of the sensor probe 6 by rotating, avoiding the surface of the sensor probe 6 The cleaning ring 95 is provided with a certain elasticity, and contacts the spring piece 98 when rotating, so that the spring piece 98 vibrates and drives the cleaning ring 95 to vibrate to a certain extent. The cleaning ring 95 shakes off the dust attached to the flexible bristles by vibration, thereby maintaining the cleanliness of the cleaning ring 95 itself. The cleaning component 9 is provided so that the cleaning ring 95 can rotate in the process of reciprocating movement left and right.
