Description

Technical Field

[0001] The utility model relates to the technical field of outdoor atmosphere research of photochemical smog chamber, specifically to a multi-angle adjustable protective device Background Art

[0002] In photochemical smog chamber research, to simulate real atmospheric photochemical reactions, it is often necessary to illuminate the interior of the chamber with natural sunlight, thereby providing realistic feedback on the production of photochemical reaction substances. To ensure that the experimental conditions truly reflect those in a natural environment, the photochemical smog chamber reactor is completely exposed to the atmosphere, allowing sunlight to directly illuminate the reactor to produce photochemical reactions. At the same time, since natural environmental factors such as rainfall, strong winds, and dust can damage and destroy the photochemical smog chamber reactor, a protective device is usually installed around the outside of the photochemical smog chamber reactor. This protective shield needs to fully expose the reactor to the atmosphere and allow direct sunlight to illuminate it.

[0003] The existing photochemical smog chamber has the following deficiencies:

[0004] 1. The opening and closing method cannot be flexibly adjusted:

[0005] Most of them use mobile guide rail type protective cover, which not only requires a large installation space for the protective cover, but also requires the installation of running tracks, which places high demands on the fixed foundation. In addition, due to the large size and weight of the protective cover, there are certain risks in the power, stability and wind resistance of its running motor. It is also unable to solve problems such as adjusting the light intensity and increased vibration during the movement of the protective cover.

[0006] 2. Uneven light intensity:

[0007] Fixed protective devices may cause uneven distribution of light intensity inside the smoke chamber, affecting the accuracy of experimental results.

[0008] 3. Poor adaptability:

[0009] The sun's altitude angle changes with the seasons and time of day, and fixed protective devices are difficult to adapt to these changes, limiting the flexibility of the experiment.

[0010] 4. Inconvenient operation:

[0011] During experimental preparation or maintenance, fixed protective devices may need to be fully opened or closed, which brings inconvenience to experimental operations.

[0012] 5. Insufficient security:

[0013] The lack of an effective adjustment mechanism may result in the inability to adjust the protection angle in time when strong light is directly exposed, increasing the risk of the experiment. Utility Model Content

[0079] In order to better illustrate the technical effects of the present invention, the present invention provides the following specific embodiments to illustrate the above technical process:

[0080] Example 1, as Figures 1 to 3 As shown, the utility model provides a multi-angle adjustable protective device, comprising: a main frame 1, an adjustment mechanism 2, a locking device 3, a protective plate device 4, a top rain cover 1.1, an arc-shaped bracket 1.2, a protective plate track 1.3, a top motor group 2.1, a bottom motor group 2.2, a lifting transmission part 2.3, a flip transmission part 2.4, an opening and closing limit 3.1, a flip limit 3.2, an emergency stop switch 3.3, a protective plate body 4.1, and a protective plate main shaft 4.2;

[0082] The arc-shaped bracket 1.2 is the main part of the main frame 1, which is used to provide the device with an installation foundation and a windproof performance of not less than level 10 and an earthquake fortification intensity of not less than 7 degrees;

[0085] The top motor group 2.1 realizes the lifting function of the protective plate device 4 through the lifting transmission part 2.3, and has an overload protection mechanism and a power-off self-locking function; a fixed pulley 2.3.1 is installed on the top of the arc-shaped bracket 1.2, and the lifting transmission part 2.3 adopts a combination of slide rails and steel wire ropes 2.3.2. The steel wire ropes 2.3.2 are connected to all protective plate main shafts 4.2 in sequence, and the protective plate main shafts 4.2 are limited by the track groove. The top motor group 2.1 drives the protective plate device 4 to move up and down along the protective plate track 1.3 through the steel wire rope 2.3.2, and realizes the folding and unfolding of the protective plate device 4 through the coupling between the protective plate devices 4 and the bottom motor group 2.2, thereby realizing the translation and tilting of this device in multiple directions.

[0086] The bottom motor group 2.2 realizes the flip angle control of the protective plate through the flip transmission part 2.4; the flip transmission part 2.2 adopts the hinge connection form to realize the multi-angle rotation adjustment of the device.

[0087] The opening and closing limit 3.1, the flip limit 3.2, and the emergency stop switch 3.3 together constitute the locking device 3, which is used to ensure that the protective device is stably locked at a specified angle and provide a timely stopping measure in case of temporary situations;

When fully opened, the protective plate devices 4 are all stacked between the two sets of protective plate tracks 1.3. When the uppermost protective plate device 4 rises to the top preset position, the upper limit position is triggered. After the rise stops, all protective plate devices 4 are deployed. If the rise continues unexpectedly, the upper limit position is triggered. At this time, all motors are powered off and automatically locked in the original position; the same applies when descending (fold first and then descend);

[0089] The flip limit 3.2 is used for multi-angle control. When it is opened, the angle is controlled by time. When it is closed, when the limit switch at the bottom is triggered, it is completely closed and stops running.

[0095] The adjustment mechanism 2 includes but is not limited to hinges, slide rails, telescopic rods, etc., which realize multi-angle adjustment of the device and ensure that the best experimental conditions can be provided under various lighting conditions.

[0098] The lifting transmission part 2.3 uses eight sets of steel wire ropes 2.3.2 and chains to control the protection plate device 4 to operate according to the set program.

[0099] The flip transmission part 2.4 uses a combination of eight sets of chains and sprockets to control the flipping of the protective plate device 4 according to the set program. The flip transmission part 2.4 is connected to the protective plate device 4 through chains and sprockets. When the top protective plate device 4 triggers the upper limit stop, the program controls the flip transmission part 2.4 to rotate to realize the deployment and folding actions of all protective plate devices 4.

[0100] The locking device 3 can quickly adjust the protective device under strong direct light or other adverse conditions to protect the safety of experimenters and equipment.

[0104] There are four groups of protective plate devices 4, each group includes 13 groups of protective plate bodies 4.1 and 26 groups of protective plate main shafts 4.2.

[0105] This utility model aims to provide a novel multi-angle adjustable protective device that can overcome the above-mentioned problems in the prior art and is particularly suitable for outdoor smoke box applications. The specific objectives are as follows:

[0106] 1. Realize multi-angle adjustment: The protective device should be able to be freely adjusted in multiple directions so that the irradiation angle and intensity can be adjusted according to the position and intensity of the sun.

[0107] 2. Improve lighting uniformity: Through multi-angle adjustment, the lighting inside the smoke box is made more uniform, improving the reliability of experimental results.

[0108] 3. Enhance adaptability: The design of the protective device should take into account the changes in different seasons and time to ensure that the best experimental conditions can be provided under various lighting conditions.

[0109] 4. Simplify the operation process: Design a simple and easy-to-use operation mechanism to facilitate experimenters to quickly adjust the position and angle of the protective device.
