Description

Technical Field

[0001] This invention relates to the field of sandstorm testing technology, specifically to an experimental apparatus and method for simulating a real sandstorm environment. Background Technology

[0002] The dust storm test is conducted using a wind tunnel to realistically simulate dust storms and haze. It is primarily used for testing the IP5X and IP6X protection ratings specified in the enclosure protection standards. The test mainly simulates the damage caused by dust storms to products such as locks, automotive and motorcycle parts, seals, and electrical instruments.

[0003] Currently, wind tunnels in my country that simulate real sandstorm environments have significant shortcomings. Although the exhaust vents of these devices are connected to the external environment, sand or haze is still directly discharged, causing pollution and contaminating the experimental environment. Furthermore, the use of fans for air supply makes it difficult to adjust the air supply vents, meaning that the air volume can only be adjusted by controlling the fans, which increases the experimental cost. To address these issues, this paper proposes an experimental device and method for simulating real sandstorm environments. Summary of the Invention

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-4 An experimental device for simulating a real sandstorm environment includes a test chamber 1, a test chamber 3 on the front of the test chamber 1, a drive chamber 4 on the bottom side of the test chamber 1, and a door 2 hinged to the front of the test chamber 3, which can be closed to seal the test environment and prevent the discharge of pollution sources.

[0032] In addition, in order to facilitate observation of the internal environment of the test chamber 3, an observation glass 23 is fixedly installed on the front of the chamber door 2. The observation glass 23 is made of transparent glass with a protection level of at least IP6X, so that the user's line of sight can be seen inside the test chamber 3. An LED light 21 is fixedly installed on the inner wall of the test chamber 3, which can provide supplementary lighting to facilitate clear observation of the test chamber 3.

[0033] In this embodiment, a sand and dust chamber 6 and a fan 5 are fixedly installed inside the drive chamber 4. An air inlet pipe 7 is connected between the air outlet of the fan 5 and the sand and dust chamber 6. The sand and dust chamber 6 is filled with sand and soil, which can blow air into the sand and dust chamber 6 through the air inlet pipe 7, thereby forming sand and dust haze.

[0034] A dust supply pipe 19 connects the dust chamber 6 and the test chamber 3, allowing the dust and haze generated inside the dust chamber 6 to be introduced into the test chamber 3 to simulate a real sandstorm environment.

[0035] Please see Figure 5-7An adjustment component is provided on the outside of the air inlet pipe 7 to adjust the air supply volume of the air inlet pipe 7. The adjustment component includes a connecting pipe 8 connected to the air inlet pipe 7. A first valve disc 9 and a second valve disc 10 are movably installed inside the connecting pipe 8. A valve hole 11 is opened on both the first valve disc 9 and the second valve disc 10. The first valve disc 9 and the second valve disc 10 are rotatably connected to each other. At the same time, a through rod 12 is rotatably installed through the first valve disc 9 and the second valve disc 10, which allows the first valve disc 9 and the second valve disc 10 to be rotatably connected relative to each other.

[0036] An extension rod 13 is fixedly installed on the inner wall of the connecting pipe 8, and a cylinder 14 is fixedly installed on the extension rod 13. The output end of the cylinder 14 is fixedly connected to the through rod 12, and the cylinder 14 can drive the first valve disc 9 and the second valve disc 10 to slide and adjust their positions inside the connecting pipe 8.

[0037] In order to enable the first valve disc 9 to rotate relative to the second valve disc 10 and to misalign the valve hole 11, a slider 15 is fixedly installed on the outside of the second valve disc 10, and a groove 16 is provided on the inner wall of the connecting pipe 8. The slider 15 is slidably connected to the groove 16, and the groove 16 is opened parallel to the inner wall of the connecting pipe 8, so that the second valve disc 10 can achieve rotation limitation by the relative sliding between the slider 15 and the groove 16 during movement.

[0038] A traction block 17 is fixedly installed on the outside of the first valve disc 9. A guide groove 18 is provided on the inner wall of the connecting pipe 8. The traction block 17 is slidably connected to the guide groove 18. The guide groove 18 is wavy and is provided on the inner wall of the connecting pipe 8, so that the first valve disc 9 can rotate relative to the second valve disc 10 when sliding on the inner wall of the connecting pipe 8, thereby causing the two valve holes 11 to be misaligned to adjust the air supply volume.

[0039] In this embodiment, a tray 20 is fixedly installed inside the test chamber 3. The tray 20 is grid-shaped, which facilitates the placement of test items. The inner bottom wall of the test chamber 3 is funnel-shaped and inclined and recessed towards the inside of the drive chamber 4. A circulation pipe 24 connected to the sand and dust chamber 6 is fixedly installed on the recessed bottom wall of the test chamber 3. The sandstorm haze and air supply inside the test chamber 3 can be discharged through the circulation pipe 24 and circulated into the inside of the sand and dust chamber 6 to complete the circulation.

[0040] It should be noted that an exhaust port 30 is fixedly installed on the outside of the circulation pipe 24. The exhaust port 30 is connected to the drive chamber 4. A filter screen is installed at the exhaust port 30 to prevent sand and dust from overflowing and to enable the fan 5 to draw the circulating air inside the drive chamber 4 for recycling.

[0041] In addition, a seal 25 is fixedly installed on one end of the circulation pipe 24 connected to the sand and dust chamber 6. A connecting port 27 is opened on the seal 25, which connects the sand and dust chamber 6 and the interior of the seal 25. A stop block 28 is slidably installed inside the seal 25, and a spring 29 is fixedly installed between the stop block 28 and the seal 25. The spring 29 can push the stop block 28 to restrict the connecting port 27. Furthermore, the sand and dust flowing into the seal 25 from inside the circulation pipe 24 presses down the stop block 28, causing the connecting port 27 to open, thereby completing the recycling of sand and dust.

[0042] The drive chamber 4 is hinged to the outside with a door 26. A sealing strip is fixedly installed on the inner wall of the door 26, so that the drive chamber 4 can be sealed after the door 26 is closed. A control panel 22 is fixedly installed on the test chamber 1 to control the cylinder 14 and the fan 5.

[0043] A method for using an experimental device that simulates a real sandstorm environment includes: 1) opening the chamber door 2, placing the object to be tested on the tray 20 inside the test chamber 3, closing the chamber door 2 and the sealing box door 26, so that the interior of the drive chamber 4 is completely sealed.

[0044] 2) Drive the fan 5 through the control panel 22, so that the fan 5 draws air from the drive chamber 4 and introduces it into the sand and dust chamber 6 to form sand and dust, and introduces it into the test chamber 3 through the dust supply pipe 19 to form a sandstorm or haze environment.

[0045] 3) The sand generated inside the test chamber 3 flows back to the inside of the seal 25 through the circulation pipe 24. After the sand accumulates, the spring 29 is pressed down, which compresses the spring 29 to open the connecting port 27, so that the sand can return to the inside of the sand and dust chamber 6. The air introduced into the test chamber 3 returns to the inside of the drive chamber 4 through the exhaust port 30, thus forming a test cycle.

[0046] In summary, during use, by driving the cylinder 14, the cylinder 14 pushes the through rod 12 downward, causing the through rod 12 to simultaneously drive the first valve disc 9 and the second valve disc 10 to slide downward synchronously. At this time, the second valve disc 10 cannot rotate due to the sliding traction of the slider 15 and the slide groove 16, while the first valve disc 9 rotates relative to the second valve disc 10 due to the sliding traction of the traction block 17 and the guide groove 18, causing the two valve holes 11 to be misaligned to adjust the air supply volume.

[0047] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
