[0015] In summary, the present invention has the following main beneficial effects:

[0016] 1. This invention designs an air blowing assembly. By starting a motor, the experimental platform is rotated to a state parallel to the operating table. During this process, the experimental platform moves the first arc-shaped piston rod and the first piston to the bottom of the inner cavity of the first arc-shaped piston cylinder. At this time, the gas inside the first arc-shaped piston cylinder is squeezed into the first air outlet pipe by the first piston, and then sprayed out through several sets of air jet pipes to blow away the dust on the surface of the operating table, preventing the dust from adhering to the surface of the operating table and being collected together, thereby affecting and damaging the internal components of the experimental platform.

[0017] 2. This invention designs a collection component. By starting a motor, the experimental platform is rotated to a position perpendicular to the operating table. During this process, the experimental platform moves the second arc-shaped piston rod and the second piston towards the top of the inner cavity of the second arc-shaped piston cylinder, creating a negative pressure inside the cylinder. Air and dust between the experimental platform and the operating table enter several sets of branch pipes and the second air inlet pipe through the suction box. The gas smoothly enters the second arc-shaped piston cylinder, while the dust, blocked by the inclined filter screen, slides down through the connecting channel into the collection box for collection. This ensures that the dust between the experimental platform and the operating table is cleaned before the device is used, further improving the dustproof effect of the device and extending its service life.

[0018] 3. This invention, through the design of a scraping component, causes each rotation of the experimental platform to drive the fixing block and the arc-shaped rack, which are fixed to one end of the first and second arc-shaped piston rods, to move in an arc shape. During this process, the two sets of gears meshing with them rotate synchronously, thereby driving the threaded screw to rotate. This causes the slider threadedly connected to the threaded screw to slide, thereby driving the scraper to scrape the surface of the operating platform, removing and cleaning the dust adhering to the surface. The dust scraped off by the scraper falls from the square opening into the collection drawer in the collection box, further improving the cleanliness of the operating platform and preventing dust accumulation on the surface. This prevents dust from being stirred up by the operator during operation, which could then have a certain impact on the device. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of the present invention will now be described.

[0034] An electrical automation experimental platform, such as Figure 1-3As shown, the device includes an operation box body 100. A rotating shaft 130 is laterally arranged at the rear end of the top of the operation box body 100. An experimental platform 140 is fixedly connected to the outer wall of the rotating shaft 130. One end of the rotating shaft 130 extends through to the outside of the operation box body 100 and is equipped with a motor 120. The motor 120 is fixedly connected to one side of the operation box body 100 via a base. An air blowing assembly 200 is installed on one side of the inner cavity of the operation box body 100, and a collecting assembly 300 is installed on the other side of the inner cavity of the operation box body 100. An operation platform 110 is fixedly installed near the top of the operation box body 100. A scraping assembly 400 is provided on the upper surface of the operation platform 110. The air blowing assembly 200 includes a first arc-shaped piston rod 210 fixedly installed on one side of the top of the experimental platform 140. The other end of the first arc-shaped piston rod 210 extends through to the bottom of the operation platform 110 and is fixedly equipped with a first piston 220. A first arc-shaped piston cylinder 230 is sleeved on the outside of the first piston 220. The bottom of the first arc-shaped piston cylinder 230 is fixedly connected to the rear end of the inner cavity of the main body 100 of the control box. A first air inlet pipe 240 is fixedly connected to one side of the bottom of the first arc-shaped piston cylinder 230. The other end of the first air inlet pipe 240 extends through to the outside of the main body 100 of the control box. A first air outlet pipe 250 is fixedly connected to the upper bottom of the first arc-shaped piston cylinder 230. The other end of the first air outlet pipe 250 extends to the inside of the top side wall of the main body 100 of the control box. A cavity matching the first air outlet pipe 250 is opened inside the top side wall of the main body 100 of the control box. Several sets of equidistantly distributed jet pipes 260 are fixedly connected to one side of the first air outlet pipe 250 located inside the top side wall of the main body 100 of the control box. The other end of each set of jet pipes 260 is connected to the outside, and the jet pipes 260 are arranged parallel to the control table 110.

[0035] After the experimental platform 140 is finished using, the operator starts the motor 120 via the controller. The output of the motor 120 drives the rotating shaft 130 to rotate, thereby rotating the experimental platform 140 to a parallel position with the operating platform 110 and storing it inside the top of the operating box body 100. This storage method can greatly save space and better protect against dust, preventing the experimental platform 140 from being exposed to the air for a long time after use, which could cause dust to enter and damage the internal components, affecting its service life. During the rotation and storage process of the experimental platform 140, the first arc-shaped piston rod 210 and the first piston 220 are moved towards the bottom of the inner cavity of the first arc-shaped piston cylinder 230. At this time, the gas inside the first arc-shaped piston cylinder 230 is squeezed into the first outlet pipe 250 by the first piston 220, and then... The air jets are sprayed through several sets of jet pipes 260 to blow away the dust on the surfaces of the experimental table 140 and the operating table 110, preventing dust from adhering to the surface of the operating table 110 and being collected together, thus affecting and damaging the internal components of the experimental table 140. When the experimental table 140 needs to be used, the operator starts the motor 120 through the controller to rotate the experimental table 140 to a position perpendicular to the operating table 110. During this process, the first arc-shaped piston rod 210 and the first piston 220 are moved to the top of the inner cavity of the first arc-shaped piston cylinder 230, so that a negative pressure is generated inside the first arc-shaped piston cylinder 230. External gas is drawn into the first arc-shaped piston cylinder 230 through the first air inlet pipe 240 to replenish the gas source for the next blowing.

[0036] Please refer to this carefully. Figure 1 , Figure 2 , Figure 4 as well as Figure 5As shown, the collection assembly 300 includes a second arc-shaped piston rod 310 fixedly installed on the other side of the top of the experimental table 140. The other end of the second arc-shaped piston rod 310 extends through to the bottom of the operating table 110 and is fixedly installed with a second piston 320. A second arc-shaped piston cylinder 330 is sleeved on the outside of the second piston 320. The bottom of the second arc-shaped piston cylinder 330 is fixedly connected to the other side of the rear end of the inner cavity of the operating box body 100. A second air inlet pipe 340 is fixedly connected to the upper bottom of the second arc-shaped piston cylinder 330. The other end of the second air inlet pipe 340 extends into the interior of the other side wall of the top of the operating box body 100. The interior of the other side wall of the top of the operating box body 100 has a cavity that matches the second air inlet pipe 340. Several sets of equidistantly distributed branch pipes 350 are fixedly connected to one side of the second air inlet pipe 340 located inside the other side wall of the top of the operating box body 100. The other end of each set of branch pipes 350 is fixedly connected to... A single suction box 360 is fixedly installed, with its opening parallel to the operating table 110. A second air outlet pipe 370 is fixedly connected to one side of the bottom of the second arc-shaped piston cylinder 330, and the other end of the second air outlet pipe 370 extends through to the outside of the main body 100 of the operating box. A connecting box 380 is fixedly sleeved on the outer wall of the inner cavity of the main body 100 of the operating box. The second air inlet pipe 340 is connected to the inside of the connecting box 380. An inclined filter screen 390 is fixedly installed inside the connecting box 380. A connecting channel 3910 with a certain angle to the horizontal direction is fixedly connected to one side of the connecting box 380. A collection box 3920 is fixedly installed at the other end of the connecting channel 3910. A pull door is fixedly installed on one side of the collection box 3920. One-way valves are installed at one end of the inner cavities of the first air inlet pipe 240, the first air outlet pipe 250, the second air inlet pipe 340, and the second air outlet pipe 370.

[0037] When the experimental platform 140 is needed, the operator starts the motor 120 via the controller. The output of the motor 120 drives the rotating shaft 130 to rotate, thereby rotating the experimental platform 140 to a position perpendicular to the operating table 110. During this process, the experimental platform 140 drives the second arc-shaped piston rod 310 and the second piston 320 to move towards the top of the inner cavity of the second arc-shaped piston cylinder 330, creating a negative pressure inside the second arc-shaped piston cylinder 330. Air and dust between the experimental platform 140 and the operating table 110 enter several sets of branch pipes 350 and the second air inlet pipe 340 through the air intake box 360. The gas smoothly enters the second arc-shaped piston cylinder 330, while the dust is filtered by the inclined filter screen 39. The dust is collected in the collection box 3920 through the connecting channel 3910 under the obstruction of 0, so that the dust between the experimental table 140 and the operating table 110 is cleaned before the device is used, which further improves the dustproof effect of the device and extends its service life. After the experimental table 140 is used, the operator starts the motor 120 through the controller to drive the experimental table 140 to rotate to a parallel state with the operating table 110. During this process, the experimental table 140 drives the second arc-shaped piston rod 310 and the second piston 320 to move to the bottom of the inner cavity of the second arc-shaped piston cylinder 330. At this time, the gas inside the second arc-shaped piston cylinder 330 is squeezed into the second outlet pipe 370 by the second piston 320 and discharged.

[0038] Please refer to this carefully. Figure 1 , Figure 2 , Figure 6 as well as Figure 7 As shown, the scraping assembly 400 includes fixing blocks 410 fixedly connected to one end of the first arc-shaped piston rod 210 and the second arc-shaped piston rod 310. Arc-shaped racks 420 are fixedly connected to one side of each of the fixing blocks 410. The other ends of the arc-shaped racks 420 extend through to the bottom of the operating table 110 and mesh with gears 440. Both sets of gears 440 are located on both sides of the top front end of the operating box body 100, and a threaded screw 450 is fixedly connected between the two sets of gears 440. A slider 460 is threadedly connected to the outer wall of the threaded screw 450. One side of the slider 460 is fixedly connected to... A scraper 461 is attached to the upper surface of the operating table 110. Square openings 470 are provided through both sides of the upper surface of the operating table 110. A collection box 480 is fixedly installed below the square openings 470 in the inner cavity of the operating box body 100. One end of the collection box 480 extends through to the outside of the operating box body 100, and a collection drawer 490 is slidably provided inside the collection box 480. Arc-shaped slide rails 430 that match two sets of arc-shaped racks 420 are fixedly installed on both sides of the inner cavity of the operating box body 100. The rear end of the arc-shaped racks 420 is slidably connected to the arc-shaped slide rails 430.

[0039] As the experimental platform 140 rotates, it causes the fixing block 410, which is fixed to one end of the first arc-shaped piston rod 210 and the second arc-shaped piston rod 310, and the arc-shaped rack 420 to move in an arc shape. Under the guidance of the arc-shaped slide rail 430, the arc-shaped rack 420 moves more stably. During this process, it will drive the two sets of gears 440 meshing with it to rotate synchronously, thereby driving the threaded screw 450 to rotate, and causing the slider 460 threadedly connected to the threaded screw 450 to start sliding, thereby driving the scraper 461 to move on the operating platform 140. 10. The surface is scraped to remove dust adhering to the surface of the operating table 110. The dust is scraped off by the scraper 461 and falls from the square opening 470 into the collection drawer 490 in the collection box 480. After a long period of use, the operator can pull the collection drawer 490 to clean the dust collected inside, which further improves the cleanliness of the operating table 110 and prevents dust from accumulating on the surface of the operating table 110. This prevents the dust from being stirred up during operation and thus affecting the device.

[0040] Please refer to this carefully. Figure 1 , Figure 2 as well as Figure 8 As shown, an L-shaped connecting block 4910 is fixedly connected to the top of one end of the scraper 461 near the slider 460. A guide wheel 4920 is installed at the other end of the L-shaped connecting block 4910. A guide groove matching the guide wheel 4920 is opened at the front end of the top of the operation box body 100. The guide wheel 4920 is slidably connected to the guide groove. A storage groove 141 matching the scraper 461 is opened at one end of the front side of the experimental table 140. A box door 150 is hinged to the outer wall of the front side of the operation box body 100.

[0041] By setting guide wheels 4920 and guide grooves, scraper 461 can move stably along the direction of guide grooves. At the same time, by setting storage slots 141, when the experimental table 140 is stored in the top of the main body 100 of the operation box, its scraper 461 will be stored in storage slots 141. It is worth noting that part of the top of the arc-shaped rack 420 is hollow, so the scraper 461 has stopped moving before the experimental table 140 is completely rotated to a state parallel to the operation table 110.

[0042] In use, the operator starts the motor 120 via the controller. The output of the motor 120 drives the rotating shaft 130 to rotate, thereby rotating the experimental platform 140 to a parallel state with the operating platform 110 and storing it inside the top of the operating box body 100. This storage method can greatly save space and better protect against dust, preventing the experimental platform 140 from being exposed to the air for a long time after use, which could damage or interfere with internal components and affect its service life. During the rotation and storage process of the experimental platform 140, the first arc-shaped piston rod 210 and the first piston 220 are moved towards the bottom of the inner cavity of the first arc-shaped piston cylinder 230. At this time, the gas inside the first arc-shaped piston cylinder 230 is squeezed into the first exhaust pipe 250 by the first piston 220, and then ejected through several sets of jet pipes 260, thereby spraying the experimental platform 140. The dust on the surface of the operating table 110 is blown away. Further, during use, dust in the air falls and adheres to the surfaces of the experimental table 140 and the operating table 110, and is collected together inside the top of the main body 100 of the operating box, thus affecting the dustproof effect. When the experimental table 140 needs to be used, the operator starts the motor 120 through the controller to rotate the experimental table 140 to a perpendicular position to the operating table 110. During this process, the first arc-shaped piston rod 210 and the first piston 220 move towards the top of the inner cavity of the first arc-shaped piston cylinder 230, creating a negative pressure inside the first arc-shaped piston cylinder 230. External gas is drawn into the first arc-shaped piston cylinder 230 through the first air inlet pipe 240, replenishing the gas source for the next blowing. Parts not mentioned in this device are the same as or can be implemented using existing technology.
