Description

Technical Field

[0001] This utility model relates to the field of dustproof test chambers, specifically a dustproof test chamber based on severe weather conditions. Background Technology

[0002] A dustproof test chamber for severe weather is a specially designed experimental device for simulating and testing the performance of products under extreme sandstorm or dusty weather. Dustproof test chambers, also known as sand and dust test chambers or dustproof testing instruments, have the core function of simulating sand and dust environments to evaluate the performance, sealing and durability of products under such environments. By using a fan to push a certain concentration of sand and dust at a certain flow rate across the surface of the test sample, the ability of these test samples (equipment) to defend against the penetration effect, abrasion or blockage effect of dust particles, as well as their ability to be stored and operated in sand and dust environments is evaluated.

[0003] In existing technology, staff usually place some items inside a dustproof test chamber for sand and dust testing before use, so that staff can determine whether the items can be used smoothly in harsh weather. When testing the items, they are usually placed inside the dustproof test chamber and sand and gravel are blown out by an air pump. However, after testing the items, a lot of dust easily adheres to the inside of the dustproof test chamber and the item placement rack. This requires staff to add sand and gravel to the inside of the dustproof test chamber or clean the sand and gravel regularly, which increases the workload of staff and makes the maintenance of the dustproof test chamber more cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, dust tends to accumulate inside the dustproof test chamber and on the object placement rack after the objects are tested. This necessitates regular addition of sand or cleaning of the sand inside the dustproof test chamber, increasing the workload and cumbersome maintenance process. This invention proposes a dustproof test chamber designed for harsh weather conditions.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dustproof test chamber based on severe weather, including a dustproof test chamber body, a closing plate rotatably connected to the inner cavity of the dustproof test chamber body, a protective plate fixedly connected to the inner cavity of the dustproof test chamber body, an air inlet pipe fixedly connected to the inner cavity of the dustproof test chamber body, an air pump fixedly connected to the surface of the air inlet pipe, a placement rack provided in the inner cavity of the dustproof test chamber body, and a scraping mechanism and a dust removal mechanism provided in the inner cavity of the dustproof test chamber body;

[0006] The scraping mechanism includes a servo motor. One side of the servo motor is fixedly connected to the top of the dustproof test chamber body. The output end of the servo motor passes through the dustproof test chamber body and is fixedly connected to a first rotating rod. The surface of the first rotating rod is rotatably connected to the inner cavity of the protective plate. A worm gear is fixedly connected to the surface of the first rotating rod. A connecting rod is rotatably connected to the inner cavity of the dustproof test chamber body. There are two connecting rods. One of the connecting rods has a worm wheel fixedly connected to its surface. The teeth of the worm wheel mesh with the teeth of the worm gear. A driven gear and a driving gear are fixedly connected to the surfaces of the two connecting rods, respectively. The teeth of the driven gear mesh with the teeth of the driving gear. A first incomplete gear is fixedly connected to one side of the driven gear. A second incomplete gear is fixedly connected to one side of the driving gear. A sliding plate is slidably connected to one side of the dustproof test chamber body. A rack is fixedly connected to one side of the sliding plate. The teeth of the rack mesh with the teeth of the first and second incomplete gears. A first connecting block is fixedly connected to one side of the sliding plate. A scraper is fixedly connected to one side of the first connecting block.

[0007] Preferably, the dust removal mechanism includes a second rotating rod, the surface of which is rotatably connected to the inner cavity of the protective plate, a cam is fixedly connected to the surface of the second rotating rod, a limiting sleeve is provided in the inner cavity of the dustproof test chamber body, a spring is fixedly connected to the inner cavity of the limiting sleeve, a slide rod is fixedly connected to one end of the spring, one end of the slide rod is fixedly connected to the bottom of the placement frame, and a drive assembly is fixedly connected to the surface of the second rotating rod.

[0008] Preferably, the drive assembly includes a first bevel gear, the inner cavity of which is fixedly connected to the surface of a first rotating rod, and a second bevel gear is fixedly connected to the surface of the second rotating rod, wherein the teeth of the first bevel gear mesh with the teeth of the second bevel gear.

[0009] Preferably, a second connecting block is fixedly connected to the surface of the limiting sleeve, and the top of the second connecting block is provided with a threaded groove.

[0010] Preferably, a limiting plate is fixedly connected to the inner cavity of the protective plate, and the surface of the limiting plate is slidably connected to the inner cavity of the first connecting block.

[0011] Preferably, a limiting plate is fixedly connected to one side of the dustproof test chamber body, and a limiting groove is formed on one side of the sliding plate. The surface of the limiting plate is slidably connected to the inner cavity of the limiting groove.

[0012] Preferably, a limiting ring block is fixedly connected to the inner cavity of the dustproof test chamber body, and the inner cavity of the limiting ring block is rotatably connected to the surface of the second rotating rod.

[0013] The advantages of this utility model are:

[0014] This invention utilizes a servo motor to smoothly drive the first rotating rod to rotate, which in turn drives the second rotating rod and the worm gear to rotate. The worm gear's rotation smoothly drives the first connecting block to reciprocate up and down, while the second rotating rod, via a cam, causes the placement rack to vibrate up and down, thus removing sand and gravel from the protective plate and placement rack surfaces. This makes maintenance of the dustproof test chamber's interior convenient and simple, improving efficiency in removing sand and gravel. It also solves the problem of dust easily accumulating inside the dustproof test chamber and on the object placement rack after testing, which previously required regular sand and gravel replenishment or cleaning, increasing workload and tedious maintenance.

Detailed Implementation

[0025] 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 scope of protection of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0027] This application discloses a dustproof test chamber based on severe weather conditions. (Refer to...) Figure 1 and Figure 6 A dustproof test chamber based on severe weather conditions includes a dustproof test chamber body 1, a closing plate 2 rotatably connected to the inner cavity of the dustproof test chamber body 1, a protective plate 4 fixedly connected to the inner cavity of the dustproof test chamber body 1, an air inlet pipe 12 fixedly connected to the inner cavity of the dustproof test chamber body 1, an air pump 7 fixedly connected to the surface of the air inlet pipe 12, a placement rack 3 provided in the inner cavity of the dustproof test chamber body 1, and a scraping mechanism 5 and a dust removal mechanism 6 provided in the inner cavity of the dustproof test chamber body 1.

[0028] The scraping mechanism 5 includes a servo motor 501. One side of the servo motor 501 is fixedly connected to the top of the dustproof test chamber body 1. The output end of the servo motor 501 passes through the dustproof test chamber body 1 and is fixedly connected to a first rotating rod 502. The surface of the first rotating rod 502 is rotatably connected to the inner cavity of the protective plate 4. A worm gear 503 is fixedly connected to the surface of the first rotating rod 502. A connecting rod 504 is rotatably connected to the inner cavity of the dustproof test chamber body 1. There are two connecting rods 504. A worm wheel 505 is fixedly connected to the surface of one of the connecting rods 504. The teeth of the worm wheel 505 mesh with the teeth of the worm gear 503. The surfaces of the two connecting rods 504 are respectively fixed... A driven gear 506 and a driving gear 507 are connected. The teeth of the driven gear 506 mesh with the teeth of the driving gear 507. A first incomplete gear 508 is fixedly connected to one side of the driven gear 506, and a second incomplete gear 509 is fixedly connected to one side of the driving gear 507. A slide plate 513 is slidably connected to one side of the dustproof test chamber body 1. A rack 510 is fixedly connected to one side of the slide plate 513. The teeth of the rack 510 mesh with the teeth of the first incomplete gear 508 and the second incomplete gear 509. A first connecting block 511 is fixedly connected to one side of the slide plate 513, and a scraper 512 is fixedly connected to one side of the first connecting block 511.

[0029] The air pump 7, through its own operation, blows external air into the dustproof test chamber body 1 through the air inlet pipe 12, agitating the sand and gravel inside the dustproof test chamber body 1. This allows the sand and gravel to impact the objects, thereby achieving dustproof testing. The placement rack 3 can smoothly place the objects. When the servo motor 501 is operating, it can smoothly drive the worm gear 503 to rotate through the first rotating rod 502. The worm gear 503, in turn, can smoothly drive the worm wheel 505 to rotate. The worm wheel 505, in turn, can smoothly drive the drive gear 507 to rotate through one of the connecting rods 504. The driven gear 506 is driven to rotate. The rotation of the driving gear 507 and the driven gear 506 can drive the first incomplete gear 508 and the second incomplete gear 509 to rotate respectively. Through the meshing of the first incomplete gear 508 and the second incomplete gear 509 with the rack 510, the rack 510 is smoothly driven to move up and down. When the rack 510 moves up and down, it can drive the scraper 512 to move together through the first connecting block 511, thereby cleaning the sand and gravel adhering to one side of the protective plate 4, so that it can fall back smoothly into the interior of the dustproof test chamber body 1, reducing the workload of the staff when maintaining the interior of the dustproof test chamber body 1.

[0030] Reference Figure 4 and Figure 5The dust removal mechanism 6 includes a second rotating rod 601, the surface of which is rotatably connected to the inner cavity of the protective plate 4. A cam 602 is fixedly connected to the surface of the second rotating rod 601. A limiting sleeve 603 is provided in the inner cavity of the dustproof test chamber body 1. A spring 604 is fixedly connected to the inner cavity of the limiting sleeve 603. A slide rod 605 is fixedly connected to one end of the spring 604. One end of the slide rod 605 is fixedly connected to the bottom of the placement frame 3. A driving assembly 606 is fixedly connected to the surface of the second rotating rod 601. When the second rotating rod 601 rotates, it can smoothly drive the cam 602 to rotate. When the cam 602 rotates, it can smoothly lift the placement frame 3. When the placement frame 3 is lifted, it can smoothly drive the slide rod 605 to move upward. After the slide rod 605 moves upward, it can drive the placement frame 3 to return to its original position through the elasticity of the spring 604. This can shake off the sand and gravel adhering to the surface of the placement frame 3, thereby further reducing the workload of the staff.

[0031] Reference Figure 5 and Figure 6 The drive assembly 606 includes a first bevel gear 6061, the inner cavity of which is fixedly connected to the surface of the first rotating rod 502. A second bevel gear 6062 is fixedly connected to the surface of the second rotating rod 601. The teeth of the first bevel gear 6061 and the teeth of the second bevel gear 6062 mesh with each other. The drive assembly 606 is configured such that when the first rotating rod 502 rotates, it can smoothly drive the second rotating rod 601 to rotate together. When the first rotating rod 502 rotates, it can drive the first bevel gear 6061 to rotate. Through the meshing of the first bevel gear 6061 and the second bevel gear 6062, the drive is achieved, thereby enabling the first rotating rod 502 and the second rotating rod 601 to rotate synchronously.

[0032] Reference Figure 7 The surface of the limiting sleeve 603 is fixedly connected to a second connecting block 14. The top of the second connecting block 14 is provided with a threaded groove 8. The threaded groove 8 on the top of the second connecting block 14 makes it convenient for the staff to install and disassemble the placement rack 3 when it is necessary to connect the placement rack 3 to the inside of the dustproof test chamber body 1.

[0033] Reference Figure 4 and Figure 5 A limiting plate 13 is fixedly connected to the inner cavity of the protective plate 4. The surface of the limiting plate 13 is slidably connected to the inner cavity of the first connecting block 511. The limiting plate 13 can limit the movement of the first connecting block 511 while blocking some gaps in the protective plate 4, reducing the sand and dust entering the interior of the protective plate 4.

[0034] Reference Figure 4 and Figure 5A limiting plate 10 is fixedly connected to one side of the dustproof test chamber body 1, and a limiting groove 11 is opened on one side of the slide plate 513. The surface of the limiting plate 10 is slidably connected to the inner cavity of the limiting groove 11. The limiting plate 10 can limit the movement of the rack 510 and the slide plate 513 through the limiting groove 11, so that the slide plate 513 can be stable enough when moving up and down and is not easy to deviate.

[0035] Reference Figure 4 The inner cavity of the dustproof test chamber body 1 is fixedly connected to a limiting ring block 9. The inner cavity of the limiting ring block 9 is rotatably connected to the surface of the second rotating rod 601. The limiting ring block 9 can support and limit the rotation of the second rotating rod 601, so that it can be stable enough when rotating and is not prone to slipping, tilting, shaking, etc.

[0036] Working Principle: When using this device, the operator can place the object to be tested on top of the placement rack 3, then close the closing plate 2. By starting the air pump 7, external air is blown into the dustproof test chamber body 1, stirring up sand and dust to simulate severe weather conditions. After the test, the operator only needs to stop the air pump 7 to observe the condition of the object. After the test is completed, the operator can start the servo motor 501. When the servo motor 501 is operating, it can smoothly drive the first rotating rod 502 to rotate, and the first rotating rod 502 drives the worm gear 503 to rotate. Utilizing the meshing between the worm gear 503 and the connecting rod 504, one of the connecting rods 504 is driven to rotate. Simultaneously, the driven gear 5... The meshing of gear 506 with the drive gear 507 drives the second incomplete gear 509 and the first incomplete gear 508 to rotate, thereby realizing the reciprocating motion of rack 510. When rack 510 reciprocates, it can smoothly scrape off the sand and gravel adhering to one side of the protective plate 4, causing it to fall back into the interior of the dustproof test chamber body 1. At the same time, the rotation of the first rotating rod 502 can also smoothly drive the first bevel gear 6061 to rotate. By using the meshing of the first bevel gear 6061 and the second bevel gear 6062, the cam 602 is driven to rotate. Through the elasticity of the spring 604, the placement rack 3 is driven to vibrate up and down, thereby removing the sand and gravel from the surface of the placement rack 3, thus reducing the workload of the staff when maintaining the interior of the dustproof test chamber body 1.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
