Description

Technical Field

[0001] The invention belongs to the technical field of natural environment testing, and in particular relates to a natural environment testing box with synergistic effects of multiple factors. Background Art

[0002] As one of the effective methods for equipment failure evaluation, natural environment testing is to expose products, especially materials and components, directly to a natural environment for a long time to determine the impact of the natural environment on them. It is usually conducted in various types of natural exposure sites, such as experiments in which materials or products are exposed to the ocean, desert, high-cold mountainous areas, etc. During the natural environment test, the role and impact of the environment on materials or products is usually a multi-factor synergistic or coupled process. For example, temperature, humidity, solar irradiance, and salinity are all typical environmental equivalents in outdoor environmental tests.

[0003] However, taking the natural environment test in a typical marine environment as an example, the existing method can only transport samples from various regions to test stations in coastal areas to carry out natural environment exposure tests. Obviously, this can only carry out a single group of tests (under the same environment) at a fixed point in the same period of time. The test cost is high and very inconvenient. Taking a certain part on marine equipment as an example, to carry out different types of natural environment tests for each group of specimens (four specimens) for one year, at least four test sites need to be selected, and the cost of the required test facilities must be no less than 100,000 yuan. Summary of the invention

[0004] The present invention aims to provide a natural environment test chamber with synergistic effects of multiple factors, which is used to solve the technical problems of "high test cost and very inconvenient test" existing in the existing natural environment test.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution.

[0006] A natural environment test box with multi-factor synergistic effects, characterized in that: a light-transmitting thin-walled dryer is used as the box body of the test box, the partition inside the dryer is used to place test samples, the space below the partition inside the dryer where the desiccant is placed is used to hold a salt solution, an agitator is arranged in the space for holding the salt solution, the driving mechanism of the agitator is installed on the top of the dryer, the rotating shaft of the agitator passes through the dryer cover and is connected to the driving mechanism; the inner cavity of the dryer constitutes an independent salt spray environment, and the outside of the dryer is a natural environment.

[0007] In order to simulate the natural environment conditions more realistically and conveniently, the partition is composed of a flat plate and an arc plate, a plurality of through holes are arranged on the flat plate, and a plurality of strip holes are arranged on the arc plate.

[0008] In order to facilitate the test, an annular boss is arranged on the inner wall of the dryer, and the edge of the flat plate and the edge of the arc plate are both located on the annular boss.

[0009] In order to facilitate the test and the taking and placing of the sample, the outer wall of the arc plate is a hemispherical surface, and the strip holes on the arc plate are arranged from top to bottom.

[0010] In order to carry out natural environment tests more specifically, a filter film is provided on the inner wall or outer wall of the dryer.

[0011] In order to carry out natural environment tests under constant salt spray conditions, the rotating shaft of the agitator is sealed to the dryer cover so that the inner cavity of the dryer is a closed salt spray environment.

[0012] Beneficial effects: The present invention cleverly realizes the physical separation of the optical channel and the salt spray channel, eliminating the salt spray spray system used in traditional natural environment tests. The energy consumption, space and transportation costs required during the test are greatly reduced, and the test cost is greatly reduced while the function is more optimized. Taking a certain part on marine equipment as an example, each group of test pieces (four test pieces) is subjected to one year of different types of natural environment tests. No special test site is required. It is only necessary to place the dryer with the sample directly in the use occasion or in an occasion that meets the irradiation requirements. The required test facility cost is less than 5,000 yuan. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described in conjunction with the accompanying drawings and specific embodiments, but the description of the following embodiments is only used to help understand the principle and core idea of ​​the present invention, and is not intended to limit the scope of protection of the present invention. It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, improvements made to the present invention also fall within the scope of protection of the claims of the present invention.

[0018] Example 1

[0019] like Figures 1 to 3As shown, a natural environment test box with multi-factor synergistic effect uses a light-transmitting thin-walled dryer as the box body of the test box. The partition in the dryer is used to place the test sample. The space 11 for placing the desiccant under the partition in the dryer is used to hold the salt solution. A stirrer 10 is arranged in the space 11 for holding the salt solution. The drive mechanism 8 of the stirrer 10 is installed on the top of the dryer. The rotating shaft 7 of the stirrer 10 passes through the dryer cover 6 and is connected to the drive mechanism 8. The drive mechanism 8 uses a waterproof motor, which is connected to the PLC controller. The inner cavity of the dryer constitutes an independent salt spray environment, and the outside of the dryer is a natural environment. Among them, the partition is composed of a flat plate 1 and an arc plate 3. A plurality of through holes 12 are arranged on the flat plate 1, and a plurality of strip holes 4 are arranged on the arc plate 3. An annular boss 2 is arranged on the inner wall of the dryer. The edges of the flat plate 1 and the arc plate 3 are both located on the annular boss 2. The outer wall of the arc 3 is a hemispherical surface, and the strip holes 4 on the arc plate 3 are arranged from top to bottom. During use, in order to carry out natural environment tests more specifically, a filter membrane is provided on the inner wall or outer wall of the dryer, and the type of filter membrane is selected according to the required filter band; in order to carry out natural environment tests under constant salt spray conditions, the rotating shaft 7 of the agitator 10 is sealed with the dryer cover 6 to make the inner cavity of the dryer a closed salt spray environment.

[0020] Example 2

[0021] A natural environment test chamber with multi-factor synergy, referring to Example 1 and combined with Figure 4 As shown, the main difference between it and embodiment 1 is that the partition adopts a flat plate 1 and the arc plate 3 is omitted.

[0022] When implementing the natural environment test, first place a salt solution of appropriate concentration in the space 11 below the partition, then place the sample directly on the flat plate 1, or insert the sample from the strip hole 4 on the arc plate 3 and support it on the flat plate 1, or place the sample directly on the arc plate 3, then cover the dryer cover 6, and then place the dryer with the sample directly in the use occasion or in an occasion that meets the irradiation requirements, then turn on the drive mechanism 8 and adjust the motor speed. After the natural environment test is completed, take out the sample for test evaluation. When in use, the salinity can be changed by controlling the speed of the motor to simulate the actual situation of breaking waves, and the humidity evaporates naturally through the saturation of the solution, which is closer to the natural state. When it is necessary to conduct tests on multiple groups of specimens at the same time, only multiple dryers need to be used, and salt solutions of different concentrations can be placed in each dryer, or the motor can be adjusted to different speeds, so as to realize multiple types of tests at fixed points in a natural environment.

[0023] This solution cleverly achieves the physical separation of the optical channel and the salt spray channel, eliminating the salt spray spray system used in traditional natural environment tests. The energy consumption, space and transportation costs required during the test process are greatly reduced, and the test cost is greatly reduced under the condition of more optimized functions. Taking a part on marine equipment as an example, each group of test pieces (four test pieces) is subjected to a one-year natural environment test of different categories. No special test site is required. The dryer with the sample only needs to be placed directly in the place of use or in an occasion that meets the irradiation requirements. The cost of the required test facilities is less than 5,000 yuan. In addition, the adoption of this solution also has the advantage of very good flexibility, and the test parameters can be flexibly and quickly changed at any time.
