Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental simulation test chamber technology, specifically to an environmental simulation test chamber. Background Technology
[0002] An environmental simulation test chamber, also known as an "environmental chamber" or "climate chamber," is a test device that can accurately reproduce various environmental parameters such as temperature, humidity, air pressure, and rain in a closed space. It condenses "nature" into a chamber, allowing samples to experience environmental stress equivalent to months or years in just a few days or even hours, thereby quickly exposing defects, verifying reliability, or obtaining performance data.
[0003] A search revealed a Chinese patent for an environmental simulation test chamber, publication number CN219051368U, which includes a high-temperature test zone. The test chamber body has a high-temperature test zone inside, a horizontal plate is fixedly installed on the inner wall of the test chamber body, a heating box is fixedly installed on the top of the horizontal plate, and a hot air outlet is fixedly installed on the bottom of the heating box.
[0004] The above-mentioned device is equipped with a heating box, a hot air outlet, a placement plate, a cold air fan, a cold air outlet, and a first slider. It can place the product in the high-temperature test area according to the required test environment, so that the product can be tested at high temperature. The cold air fan and the cold air outlet can be used to test the product at low temperature. This can be done simultaneously to achieve multi-layer testing. However, its rain test section is relatively simple, only simulating natural rainfall, which makes it less flexible in use. Also, when the sample is placed statically in the test chamber, it can only simulate the data when it is not subjected to mechanical stress. If it is used in environments with bumps and vibrations, its originally qualified seals, coatings and welds may fail. Utility Model Content

[0016] 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.
[0017] Example 1 Combination Figures 1-3An environmental simulation test chamber includes a test chamber body 1, a battery 7 is installed at the back of the test chamber body 1, a door is movably connected to the front of the test chamber body 1, and a silicone sealing ring is provided at the connection between the door and the test chamber body 1, a high temperature test chamber is provided on one side of the interior of the test chamber body 1, and a low temperature test chamber is provided on the other side of the interior of the test chamber body 1.
[0018] See Figure 2 and Figure 3 Furthermore, the test chamber 1 has several high-temperature test placement plates 2 inside the high-temperature test chamber and several low-temperature test placement plates 3 inside the low-temperature test chamber. A cold air blower 4 and a hot air blower 5 are installed at the upper part of the test chamber 1. The outlet of the cold air blower 4 is connected to a cold air delivery pipe, and the outlet of the hot air blower 5 is connected to a hot air delivery pipe. A rainwater test chamber is located in the center of the test chamber 1. Through the high-temperature test chamber and the low-temperature test chamber, the sample can be tested at high or low temperatures. Two sets of stainless steel infusion pipes 9 are installed at the upper part of the rainwater test chamber through the mounting bracket 11. A quartz nozzle 10 is installed at the bottom end of the stainless steel infusion pipe 9. The inlets of the two sets of stainless steel infusion pipes 9 are respectively connected to the water infusion pipe 13 and the salt spray delivery pipe 14. The connection between the stainless steel infusion pipes 9, the salt spray delivery pipe 14 and the water infusion pipe 13 is provided with an infusion solenoid valve 12. By opening the infusion solenoid valve 12, the salt spray or water flow is delivered to the rainwater test chamber for spraying. A support plate 15 is provided at the lower part of the interior of the rainwater test chamber, and a drain pump 16 is provided at the bottom of the support plate 15. The end of the hot air delivery pipe away from the hot air blower 5 extends into the high temperature test chamber, and the end of the cold air delivery pipe away from the cold air blower 4 extends into the low temperature test chamber. Ventilation openings 6 are provided at the upper part of both sides of the test chamber body 1. A temperature sensor 18 that is compatible with the cold air blower 4 and the hot air blower 5 is provided at the lower part of the interior of the test chamber body 1, and a drain pipe 17 is provided at the lower part of the outer side of the test chamber body 1.
[0019] Specifically, by using the hot air blower 5 with a hot air outlet, a high-temperature environment can be simulated when the sample is placed on the high-temperature test plate 2. By using the cold air blower 4 with a cold air outlet, the changes that the sample will undergo in a low-temperature environment can be simulated. At the same time, during the test, the salt spray delivery pipe 14 can be pre-connected to the external salt spray transmission pipe. By connecting the water pipe 13, after the sample is placed on the support plate 15, the changes that the sample will undergo under continuous rain or salt spray environment can be simulated by intermittently opening the infusion solenoid valve 12. At the same time, the infusion solenoid valve 12 corresponding to the water pipe 13 or the salt spray delivery pipe 14 can be opened separately to simulate the changes that the sample will undergo under rain or salt spray environment alone. The drainage pump 16 can be used to extract the dripping water for discharge or collection. At the same time, when treating the salt spray wastewater, a suitable solution needs to be used for neutralization treatment to meet the environmental protection emission requirements.
[0020] Example 2 See Figure 2 Furthermore, based on Example 1, a vibration motor 19 is installed at the center of the bottom of the test chamber body 1. Buffer spring seats 20 are installed at the corners of the bottom of the test chamber body 1, and a support frame 21 is installed at the bottom of the buffer spring seats 20. The vibration motor 19 is started to drive the test chamber body 1 to vibrate, which is used to simulate the test data when the sample is continuously subjected to mechanical stress. A control panel 8 is set at the top of the test chamber body 1, and an electrical control box is set at the upper rear end of the test chamber body 1. The electrical control box is electrically connected to the control panel 8, the drain pump 16, the hot air blower 5, the cold air blower 4, and the vibration motor 19. Self-locking casters are set at the front and rear ends of the bottom of the support frame 21. An adjusting rod is threaded through the center of the upper and lower ends of the support frame 21. An anti-slip plate 22 is rotatably installed at the bottom of the adjusting rod, and the bottom surface of the anti-slip plate 22 is provided with anti-slip texture.
[0021] Specifically, during the above experiment, personnel can activate the vibration motor 19 as needed. The vibration motor 19 can generate high-frequency vibration in the test chamber body 1, while the sample is inside the test chamber body 1, thus subjecting the sample to scenarios such as bumping, jumping, and shaking to simulate real mechanical stress and detect whether the sample has micro-cracks, weld fatigue, or other phenomena. At the same time, continuous shaking can verify the sealing performance of the sample under rain conditions. The test chamber body 1 is supported by the buffer spring seat 20 and the support base 21 in conjunction with self-locking casters to buffer the vibration. Furthermore, by supporting the anti-slip plate 22 by contacting the bottom surface with the ground, the support stability can be further improved.
[0022] In actual operation, the hot air blower 5, in conjunction with the hot air outlet, can simulate a high-temperature environment when the sample is placed on the high-temperature test plate 2. The cold air blower 4, in conjunction with the cold air outlet, can simulate the changes that the sample will undergo in a low-temperature environment. At the same time, during the test, the salt spray delivery pipe 14 can be pre-connected to the external salt spray transmission pipe. By connecting the water pipe 13, after the sample is placed on the support plate 15, the changes that the sample will undergo under continuous rain or salt spray environment can be simulated by intermittently opening the infusion solenoid valve 12. At the same time, the infusion solenoid valve 12 corresponding to the water pipe 13 or the salt spray delivery pipe 14 can be opened separately to simulate the changes that the sample will undergo under rain or salt spray environment alone. The drainage pump 16 can be used to extract the dripping water for discharge or collection. At the same time, when treating the salt spray wastewater, a suitable solution needs to be used for neutralization treatment to meet the environmental protection emission requirements. During the experiment, personnel can activate the vibration motor 19 as needed. The vibration motor 19 can generate high-frequency vibration in the test chamber body 1, while the sample is inside the test chamber body 1, thus subjecting the sample to scenarios such as bumping, jumping, and shaking to simulate real mechanical stress and detect whether the sample has micro-cracks, weld fatigue, etc. At the same time, continuous shaking can verify the sealing performance of the sample under rain conditions. The test chamber body 1 is supported by the buffer spring seat 20 and the support base 21 in conjunction with self-locking casters to buffer the vibration. Furthermore, by supporting the sample by having the bottom surface of the anti-slip plate 22 in contact with the ground, the support stability can be further improved. This solution can be appropriately selected according to the sample conditions and is not limited to one or two detection conditions, nor can it achieve all simulation effects at the same time. Personnel can make adjustments as needed, so no further details are provided. The technical solution described in this embodiment shall prevail. Furthermore, the display and control components and modules used in the aforementioned temperature sensor 18, vibration motor 19, and drainage pump 16 are all existing technologies, which can be fully implemented by those skilled in the art. The power supply is also common knowledge in the field and need not be elaborated upon. No specific model is required; it is sufficient to meet the usage requirements. The content protected by this utility model does not involve improvements to the software and methods. Moreover, this utility model is mainly used to protect mechanical mechanisms, so the control method and circuit connection will not be explained in detail in this utility model.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
