Description

Technical Field

[0001] The invention belongs to the technical field of sand and dust environment simulation tests, and in particular relates to a mobile sand and dust environment simulation device. Background Art

[0002] Dust environment simulation test equipment is a specialized device used to simulate natural dust environments for performance testing and evaluation of products or materials. In fields such as aerospace, automotive manufacturing, electronics, and building materials, products may be used or exposed to dusty environments. Dust environment simulation test equipment can help companies and research institutions understand in advance the product's tolerance and reliability in dusty environments. The equipment primarily uses a fan to generate a powerful airflow, blowing dust particles of a specific size and concentration into the test chamber, creating an environment similar to a natural sandstorm. The test chamber is typically equipped with a temperature and humidity control system to simulate dusty environments under different climatic conditions, allowing for more comprehensive testing of product performance.

[0003] However, after the test is completed, there will be a large amount of dust on the inner wall of the working chamber. Therefore, when the staff opens the door of the closed working chamber, since the inside of the working chamber is in a closed state, opening the door will cause the air pressure in the working chamber to change, thereby causing the dust in the working chamber to be lifted up, and the dust will float out of the working chamber and affect the staff.

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0032] Example 1, as Figure 1-9 As shown, a mobile dust environment simulation device of the present invention includes a box body 1, universal wheels 101 are provided at the four corners of the lower side of the box body 1, a bracket 11 is provided on one side of the box body 1, and the bracket 11 is equipped with a control box 12, a working chamber 13 is provided on the upper side of the box body 1, and a box door 14 matching the working chamber 13 is provided on the outside of the box body 1, a groove 2 is provided on one side of the working chamber 13, a filter plate 21 is installed in the groove 2, and the groove 2 is connected to an adsorption mechanism, the adsorption mechanism includes a mounting frame 22 provided on the side of the box body 1, a sliding seal is provided in the mounting frame 22, a rebound mechanism is provided on the upper side of the skateboard 23, and a connecting mechanism connected to the box door 14 is provided on the upper surface of the skateboard 23, and the connecting mechanism is used to drive the skateboard 23 to move upward in the mounting frame 22 when the box door 14 is opened, a one-way air outlet mechanism is provided on the lower side of the mounting frame 22, and a one-way air intake mechanism connected to the groove 2 is also provided on the lower side of the mounting frame 22.

[0033] The staff can place the workpiece to be tested in the working chamber 13, and can perform dust test on the workpiece after closing the box door 14. When the test is completed, the staff needs to open the box door 14 to take out the workpiece. The staff opens the box door 14, and the box door 14 drives the slide 23 in the installation frame 22 to move upward through the connecting mechanism, and the rebound mechanism is compressed. Since the slide 23 is slidingly sealed and assembled in the installation frame 22, when the slide 23 moves upward, a negative pressure can be formed on the lower side of the installation frame 22, and the suction force is transmitted into the groove 2. This design is convenient for the box The moment the door 14 is opened, suction is generated at the position of the groove 2, so that the dust raised by the working chamber 13 can be adsorbed to the position of the groove 2, and because the groove 2 is externally equipped with a filter plate 21, the filter plate 21 can filter the dust and let the dust fall on the surface of the filter plate 21. This design allows the inner wall of the working chamber 13 to adsorb the floating dust when the box door 14 is opened, effectively preventing the dust from floating out of the working chamber 13. When the staff closes the box door 14, the rebound mechanism stretches and drives the slide plate 23 to move downward and reset.

[0034] The one-way air intake mechanism includes a cavity 231 provided in the box body 1, and the inner wall of the cavity 231 is provided with a plurality of air holes 24 connected to the groove 2. The lower inner wall of the mounting frame 22 is provided with a connecting pipe 25 connected to the cavity 231, and the connecting pipe 25 is equipped with a one-way air intake valve 26.

[0035] When the slide plate 23 moves upward in the mounting frame 22, negative pressure is formed on the lower side of the mounting frame 22. The negative pressure is transmitted into the cavity 231 through the connecting pipe 25, and then transmitted into the groove 2 through a plurality of air holes 24, thereby adsorbing the dust floating in the working chamber 13.

[0036] The one-way air outlet mechanism includes an air outlet pipe 27 provided on the lower side of the mounting frame 22 , and the air outlet pipe 27 is equipped with a one-way air outlet valve 28 .

[0037] When the slide plate 23 moves downward and resets in the mounting frame 22 , the gas in the lower side of the mounting frame 22 can be squeezed and provided to the gas outlet pipe 27 for discharge outward.

[0038] The rebound mechanism includes a slide bar 3 provided on both sides of the mounting frame 22. The left and right sides of the slide plate 23 are slidably sleeved on the outer surface of the slide bar 3 on the same side. The upper sides of the two slide bars 3 are sleeved with a first spring 31, and the two first springs 31 are both located on the upper side of the slide plate 23.

[0039] The slide plate 23 can slide up and down relative to the slide bars 3 on both sides. When the slide plate 23 moves upward, it can compress the first spring 31. When the pull on the slide plate 23 is released, the slide plate 23 can be driven to move downward and reset under the action of the first spring 31 extension.

[0040] The connecting mechanism includes a pull wire 32 connected to the upper surface of the slide 23 , one end of the pull wire 32 is connected to a fixing block 33 fixedly connected to the box door 14 , and the box body 1 is provided with a plurality of wire members 34 matching the pull wire 32 .

[0041] When the staff opens the box door 14, the fixed block 33 is driven to move. Since the fixed block 33 is connected to the pull wire 32, and the other end of the rain-proof pull wire 32 is connected to the slide plate 23, the slide plate 23 can be driven to move upward. When the box door 14 is closed, the pulling of the pull wire 32 is cancelled, and the design of the wire member 34 can guide the turning of the pull wire 32.

[0042] Example 2, as Figure 2-9 As shown, the inner wall of the working chamber 13 is provided with two chutes 4 respectively located on both sides of the groove 2, and a movable frame 41 is slidably assembled between the two chutes 4. The movable frame 41 extends into the two chutes 4 and one end matches the position of the slide 23. The slide 23 is an iron slide. Both ends of the movable frame 41 that match the position of the iron slide are provided with a first magnet block 43. The movable frame 41 is equipped with a cleaning brush 44 that matches the filter plate 21.

[0043] A first magnet block 43 is provided at both ends of the movable frame 41, and the movable frame 41 matches the position of the slide plate 42 in the slide groove 4. Since the slide plate 42 is an iron slide plate, the first magnet block 43 can adsorb the slide plate 42. When the slide plate 42 slides up and down, it drives the movable frame 41 to move up and down. Since the movable frame 41 is equipped with a cleaning brush 44, when the slide plate 42 slides up and down, it can drive the cleaning brush 44 to move up and down, and the cleaning brush 44 cleans the surface of the filter plate 41. This design prevents dust from completely covering the filter plate 41 and causing clogging of the filter plate 41.

[0044] The movable frame 41 is provided with a through slot 5 in the middle, and a movable plate 51 is slidably assembled in the through slot 5, and a cleaning brush 44 is assembled on the side of the movable plate 51 facing the filter plate 21. Telescopic slots 52 are provided on both sides of the movable frame 41, and connecting pieces 53 connected to the movable plate 51 are slidably assembled in the two telescopic slots 52. A step hole 54 is provided on the upper side of the telescopic slot 52, and a second spring 55 is provided on the upper side of the step hole 54. A T-shaped lock piece 56 that can extend out of the step hole 54 is provided on the lower side of the second spring 55. Lock holes 57 matching the T-shaped lock piece 56 are provided on the left and right sides of the upper side of the connecting piece 53. The lower end of the T-shaped lock piece 56 is arc-shaped. Second magnet blocks 58 are provided on the end faces of the two connecting pieces 53 facing the filter plate 21. Third magnet blocks 581 that are magnetically attracted to the second magnet block 58 are provided on the left and right sides of the upper side of the filter plate 21, and fourth magnet blocks 582 that are magnetically repelled from the second magnet block 58 are provided on the left and right sides of the lower side of the filter plate 21.

[0045] When the movable frame 41 is located at the lower side of the filter plate 21, the positions of the second magnet blocks 581 on both sides match the positions of the fourth magnet blocks 582. Since the second magnet blocks 58 and the fourth magnet blocks 582 magnetically repel each other, the connecting member 53 can be pushed to move away from the filter plate 21. Since the connecting member 53 is connected to the movable plate 51, the movable plate 51 can be pushed to move away from the filter plate 21. Since the cleaning brush 44 is connected to the filter plate 21, it drives the cleaning brush 44 away from the filter plate 21. When the movable frame 41 is located at the upper side of the filter plate 21, since the second magnet blocks 58 and the fourth magnet blocks 582 are magnetically repelled, the connecting member 53 can be pushed to move away from the filter plate 21. The three magnet blocks 581 are magnetically attracted to each other, so that the movable plate 51 can be attracted to move toward the side of the filter plate 21 through the connecting piece 53, so that the cleaning brush 44 matches the filter plate 21. With this design, when the bracket 11 moves upward, the cleaning brush 44 does not contact the surface of the filter plate 21, and when the bracket 11 moves downward, the cleaning brush 44 contacts the surface of the filter plate 21. With this design, the filter plate 21 will not be cleaned when the box door 14 is opened, and the surface of the filter plate 21 will be cleaned only when the box door 14 is closed, thereby reducing the possibility of sand and dust drifting out of the working chamber 13;

[0046] Under the action of the extension of the second spring 55, the T-shaped lock piece 56 is pushed downward and locked into one of the lock holes 57. When the connecting piece 53 moves in the telescopic slot 52, since the lower end of the T-shaped lock piece 56 is an arc-shaped lock-in lock hole 57, when the bracket 11 moves under the action of magnetism, the magnetic attraction or repulsion can overcome the elastic force of the second spring 55, pushing the connecting piece 53 to move, and the T-shaped lock piece 56 can move out of one lock hole 57 until the T-shaped lock piece 56 matches the position of the other lock hole 57. Under the action of the extension of the second spring 55, the lower end of the T-shaped lock piece 56 is locked into the lock hole 57 to limit the connecting piece 53. This design can limit the two positions of the movable plate 51 and will not slide easily.

[0047] A storage cavity is provided at the bottom of the working cavity 13 , and a grid 59 matching the storage cavity is provided at the bottom of the working cavity 13 .

[0048] The dust in the working chamber 13 will fall downward into the storage chamber, and the grid 59 can support the workpiece being tested.

[0049] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
