Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring equipment technology, and in particular to an environmental monitoring device with adjustable height and angle. Background Technology

[0002] Environmental monitoring equipment is a specialized instrument used to monitor environmental elements such as air, water quality, and soil. Currently, most environmental quality monitoring equipment adopts an integrated design scheme, usually with a control box as the core, integrating multiple detection modules. Environmental monitoring instruments such as wind direction sensors and air volume sensors are installed on the top of the control box. This layout facilitates the unified management and maintenance of the equipment and allows the sensors to have more direct contact with the external environment, reducing detection interference.

[0003] A search revealed that Chinese Patent Publication No. CN218481120U discloses an environmental monitoring device. This device includes a hollow tube, a wind force sensor, a temperature and humidity sensor, and a wind direction sensor. The bottom of the hollow tube is provided with a support and reinforcement mechanism. A transmission box is fixedly installed in the middle of the hollow tube by a clamp. A solar power generation mechanism is provided above and behind the transmission box. The top of the hollow tube is provided with the wind force sensor, the temperature and humidity sensor, and the wind direction sensor.

[0004] However, most current environmental monitoring devices are equipped with sensors for airflow, wind speed, etc., which are mostly bolted to the top of the control box. For example, the wind force sensor, temperature and humidity sensor, and wind direction sensor are mounted on the top of the hollow tube in the aforementioned patent. This fixing method prevents the sensor height from being flexibly adjusted according to actual needs. Since wind speed and airflow vary significantly at different heights, the fixed-height design greatly limits the sensor's detection range, making it difficult to comprehensively and accurately reflect the environmental airflow conditions at different height levels. Therefore, this paper proposes an environmental monitoring device with adjustable height and angle to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 3This utility model provides an embodiment of an adjustable height and angle environmental monitoring device, comprising a housing 1. The housing 1 can integrate control equipment and monitoring equipment for environmental monitoring. A column 2 is fixedly connected to the back of the housing 1. A slide rod 3 is slidably connected to the inner wall of the column 2. A support platform 4 is hinged to the top of the slide rod 3. A wind speed sensor 5 and a wind direction sensor 6 are fixedly connected to the top of the support platform 4. The height of the support platform 4 can be adjusted by sliding the column 2 up and down, thereby adjusting the height of the wind speed sensor 5 and the wind direction sensor 6 at the top of the support platform 4 to measure the wind speed and wind direction at different heights. An adjustment mechanism 7 is provided inside the column 2, and a protective mechanism 8 is provided on the outer wall of the column 2.

[0034] Reference Figure 1 , Figure 3 and Figure 5 The adjusting mechanism 7 includes a threaded rod 71, which is rotatably connected to the inner wall of the column 2. The threaded rod 71 is threadedly connected to the slide rod 3. A worm gear 72 is fixedly connected to the outer wall of the threaded rod 71. When the worm gear 72 rotates, it drives the threaded rod 71 to rotate synchronously on the inner wall of the column 2. The rotation of the threaded rod 71 can drive the slide rod 3, which is threaded to it, to slide up and down on the inner wall of the column 2. A motor 73 is fixedly connected to the inner wall of the housing 1. A worm gear 74 is fixedly connected to the output end of the motor 73. 74 is rotatably connected to the inner wall of the housing 1 and the column 2. The worm 74 meshes with the worm wheel 72. The starting motor 73 drives the worm 74 to rotate. When the worm 74 rotates, it will drive the worm wheel 72 to rotate. An electric push rod 75 is hinged to the inner wall of the support platform 4. The output end of the electric push rod 75 is hinged to the outer wall of the slide rod 3. The electric push rod 75 is started to push or pull the support platform 4, so that the support platform 4 rotates on the top of the column 2, thereby adjusting the tilt angle of the support platform 4.

[0035] Reference Figure 1 - Figure 3 The protective mechanism 8 includes a support rod 81. One end of the support rod 81 is fixedly connected to the outer wall of the column 2, and the other end of the support rod 81 is rotatably connected to a rotating shaft 82. A cover plate 83 is fixedly connected to the shaft end of the rotating shaft 82. The rotation of the rotating shaft 82 can drive two sets of cover plates 83 to open or close together. There are two sets of cover plates 83. The two sets of cover plates 83 are mirror images of the column 2 on the front and rear sides of the column 2 with the column 2 as the central axis. When the two sets of cover plates 83 are closed, they can cover the entire support platform 4, thereby protecting the wind speed sensor 5 and the wind direction sensor 6 from damage caused by hail and blizzard.

[0036] Reference Figure 4A gear 84 is fixedly connected to the outer wall of the rotating shaft 82, and a sliding frame 85 is slidably connected to the outer wall of the support rod 81. A rack 86 is fixedly connected to the side wall of the sliding frame 85. The rack 86 meshes with the gear 84. When the sliding frame 85 moves downward, it will drive the rack 86 to move downward synchronously. At this time, the gear 84 can drive the rotating shaft 82 to rotate on the inner wall of the support rod 81.

[0037] Reference Figure 4 A spring 87 is fixedly connected to the inner wall of the sliding frame 85. The end of the spring 87 away from the sliding frame 85 is fixedly connected to the bottom of the support rod 81. When the pressure plate 88 moves upward and disengages from the sliding frame 85, the elasticity of the spring 87 can drive the sliding frame 85 to slide upward and reset on the outer wall of the support rod 81. A pressure plate 88 is fixedly connected to the outer wall of the sliding rod 3. The pressure plate 88 is located directly above the sliding frame 85. When the sliding rod 3 slides downward, it will drive the pressure plate 88 to move downward synchronously. When the pressure plate 88 contacts the top of the sliding frame 85 during the downward movement, the pressure plate 88 will push the sliding frame 85 downward, causing the sliding frame 85 to slide downward on the outer wall of the support rod 81.

[0038] Working principle: The starting motor 73 drives the worm gear 74 to rotate. As the worm gear 74 rotates, it drives the worm wheel 72 that meshes with it to rotate. At this time, the worm wheel 72 drives the threaded rod 71 to rotate on the inner wall of the column 2. The rotation of the threaded rod 71 can drive the slide rod 3 that is threaded to it to slide up and down on the inner wall of the column 2. The height of the support platform 4 can be adjusted by sliding the column 2 up and down, so as to adjust the height of the wind speed sensor 5 and the wind direction sensor 6 on the top of the support platform 4, so as to measure the wind speed and wind direction at different heights.

[0039] When installing the testing equipment, the electric push rod 75 can be activated to push or pull the support platform 4, causing the support platform 4 to rotate on top of the column 2. This allows adjustment of the tilt angle of the support platform 4, ensuring that the horizontal error of the wind speed sensor 5 and the wind direction sensor 6 is ≤0.5°, which helps improve the detection accuracy of the wind speed sensor 5 and the wind direction sensor 6.

[0040] In the event of severe weather, such as hail or blizzard, the rotation of the threaded rod 71 causes the sliding rod 3 to continuously move downward on the inner wall of the column 2. At this time, the sliding rod 3 will cause the pressure plate 88 to move downward synchronously. When the pressure plate 88 contacts the top of the sliding frame 85 during its downward movement, the pressure plate 88 will push the sliding frame 85 downward, causing the sliding frame 85 to slide downward on the outer wall of the support rod 81. At this time, the sliding frame 85 will stretch the spring 87 and drive the rack 86 to move downward synchronously. As the rack 86 moves downward, it will drive the gear 84 meshing with it to rotate. At this time, the gear 84 will drive the rotating shaft 82 to rotate on the inner wall of the support rod 81. While the rotating shaft 82 is rotating, it will drive the cover plate 83 to rotate upward in a circular motion around the rotating shaft 82 until the two sets of cover plates 83 are closed together, which will shut off the motor 73. At this time, the cooperation of the two sets of cover plates 83 can cover the entire support platform 4, thereby protecting the wind speed sensor 5 and the wind direction sensor 6 and preventing hail or blizzard from damaging the sensors.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
