Description

Technical Field

[0001] This utility model relates to the field of vacuum pump technology, and more specifically, to a portable vacuum pump experimental platform. Background Technology

[0002] A portable vacuum pump experimental platform is an equipment platform specifically designed for experiments and research, featuring flexible mobility and multifunctional integration. Its mobility is reflected in the platform's design with casters, foldable supports, and other mechanisms for easy movement, allowing for easy transfer between different experimental sites to meet diverse needs. The platform integrates a vacuum pump system as the core equipment, capable of generating, controlling, and maintaining the vacuum environment required for experiments, with customizable performance parameters. Furthermore, the platform integrates auxiliary equipment such as pressure sensors and flow meters to achieve precise control and monitoring of experimental conditions. Its modular design facilitates functional expansion or upgrades, while abundant interfaces and fixing devices allow users to easily install and disassemble experimental equipment, adapting to various experimental types and improving experimental efficiency and flexibility. Traditional portable vacuum pump experimental platforms use bolts and nuts to mount the screw air compressor on top, which, while providing a certain degree of stability, also presents several problems. In terms of installation and maintenance, the precise alignment and tightening of bolts and nuts is crucial, a complex process requiring specialized tools and skills. Improper installation can easily lead to loose bolts or slipped nuts, affecting the stability and safety of the air compressor. Furthermore, disassembly for maintenance is cumbersome, especially in space-constrained environments like the top, where corrosion or wear after long-term use further complicates and increases costs. In addition, vibration and noise issues cannot be ignored. Vibration generated by the screw air compressor during operation is transmitted to the experimental platform through the bolts and nuts, affecting the platform's stability and the normal operation of other equipment. Prolonged vibration can also cause bolts and nuts to loosen or fracture due to fatigue, exacerbating the problem. Simultaneously, vibration and compressor noise are transmitted to the surrounding environment through rigid connections, causing noise pollution that not only disrupts the experimental environment but may also adversely affect the health of personnel.

[0015] The beneficial effects of the embodiments disclosed herein are as follows:

[0016] 1. Compared with traditional experimental platforms, this invention, through the cooperation of positioning blocks, springs, and pull rods, facilitates the installation of the screw air compressor on the top of the mounting base. This greatly enhances the versatility and flexibility of the experimental platform, enabling it to easily adapt to various experimental air source requirements. Both high-pressure and low-pressure air sources can be quickly configured, and experimental configurations can be rapidly switched when experimental needs change, improving response speed. Furthermore, the stable mounting foundation and reasonable fixing device ensure the stability of the screw air compressor during operation, reducing vibration and noise, and lowering safety risks. Simultaneously, optimized airflow control improves air source utilization efficiency, reduces energy consumption, and extends equipment life. In addition, the simplified installation process and standardized interface design reduce installation time and workload, while the reasonable installation design facilitates daily maintenance and fault diagnosis, reducing maintenance costs and downtime, comprehensively improving experimental efficiency and convenience.

[0017] 2. Compared with traditional experimental platforms, this utility model, through the cooperation between the sleeve block and the bidirectional screw, facilitates the limiting plate's control of the vacuum pump. The bidirectional screw's ingenious design features opposite threads at both ends; when the bidirectional screw is rotated, the sleeve blocks at both ends move synchronously towards the center or ends. This design allows for precise and flexible adjustment of the limiting plate's position, quickly adapting to vacuum pumps of different sizes and shapes. The limiting plate acts directly on the vacuum pump, tightly cooperating with the sleeve block and bidirectional screw to achieve precise positioning and quickly change its fixed position according to experimental needs. When the screw rotates to the appropriate position, the sleeve block drives the limiting plate to firmly clamp the vacuum pump, forming a stable mechanical lock, which is more reliable than traditional clamping devices, effectively preventing pump movement or shaking, enhancing experimental safety, and protecting the bidirectional screw from external impacts. Furthermore, this design greatly improves experimental efficiency and convenience, allowing for quick installation and disassembly of the vacuum pump, simplifying operation, and reducing the difficulty and labor intensity for experimental personnel.

It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-5 As shown, a portable vacuum pump experimental platform according to an embodiment of the present disclosure is illustrated, including an experimental platform 1. A mounting base 4 is fixedly installed on the top of the experimental platform 1. A mounting block 5 is movably installed inside the mounting base 4. A screw air compressor 2 is fixedly installed on the top of the mounting block 5. A housing 18 is fixedly installed on the outer side of the mounting base 4. A positioning block 16 is movably installed inside the mounting block 5. A pull rod 17 is fixedly installed at one end of the positioning block 16, and both ends of the pull rod 17 pass through the housing 18. A spring 19 is fixedly installed between the housing 18 and the positioning block 16. A push rod 6 is fixedly installed on the front of the mounting block 5.

[0032] First, the operator installs the screw air compressor 2 on top of the mounting block 5. Then, holding the pull rod 17, the operator pulls the positioning block 16 inside the mounting base 4, causing it to press against the spring 19 and pass through the mounting base 4 into the housing 18. Next, holding the push rod 6, the operator aligns the mounting block 5 with the inside of the mounting base 4 and slowly pushes it into the mounting base 4. The mounting block 5 then moves the screw air compressor 2 synchronously. When the mounting block 5 is fully inside the mounting base 4, the operator releases the pull rod 17, and the spring 19 presses against the positioning block 16, causing it to quickly enter the mounting block 5, thus completing the installation of the screw air compressor 2.

[0033] During assembly, the screw air compressor 2 must first be securely installed on top of the mounting block 5. Then, the screw air compressor 2 is reconfirmed and fixed in its position on top of the mounting block 5. Next, the operator holds the pull rod 17 and pulls it to move the positioning block 16 inside the mounting base 4. During this process, the positioning block 16 compresses the spring 19, thus smoothly passing through the mounting base 4 and entering the housing 18. Immediately afterward, the operator holds the component push rod 6 and uses it to align the mounting block 5 with the inside of the mounting base 4, slowly pushing it into the mounting base 4. This action causes the screw air compressor 2 to move synchronously. When the mounting block 5 is fully inside the mounting base 4, the operator releases the pull rod 17. At this time, the spring 19 compresses the positioning block 16 in the opposite direction, causing the positioning block 16 to quickly snap into the mounting block 5. Thus, the installation of the component screw air compressor 2 is successfully completed. Compared with traditional experimental platforms, this… Compared to other experimental platforms, the screw air compressor 2 is easily installed on top of the mounting base 4 through the cooperation between the positioning block 16, spring 19, and pull rod 17. This greatly improves the versatility and flexibility of the experimental platform, allowing it to easily adapt to various experimental air source requirements. Both high-pressure and low-pressure air sources can be quickly configured, and experimental configurations can be quickly switched when experimental needs change, improving response speed. On the other hand, the stable installation foundation and reasonable fixing device ensure the stability of the screw air compressor 2 during operation, reducing vibration and noise, and lowering safety risks. At the same time, optimized airflow control improves air source utilization efficiency, reduces energy consumption, and extends equipment life. In addition, the simplified installation process and standardized interface design reduce installation time and workload, while the reasonable installation design also facilitates daily maintenance and fault diagnosis, reducing maintenance costs and downtime, and comprehensively improving experimental efficiency and convenience.

[0034] In some examples, the experimental platform 1 has a slide groove 20 inside, a sleeve block 10 is movably installed inside the slide groove 20, a double-ended screw 11 is threaded inside the sleeve block 10, and both ends of the double-ended screw 11 pass through the interior of the experimental platform 1. A first gear 12 is fixedly installed at one end of the double-ended screw 11, a motor 14 is fixedly installed on the front of the experimental platform 1, and a second gear 13 is fixedly installed at the output end of the motor 14, and the second gear 13 meshes with the first gear 12.

[0035] A movable plate 7 is fixedly installed on the top of the sleeve block 10, a connecting column 8 is fixedly installed on the inner side of the movable plate 7, a limit plate 9 is fixedly installed on one end of the connecting column 8, and a vacuum pump 21 is movably installed on the top of the experimental platform 1.

[0036] Before using the vacuum pump 21, the operator needs to limit and fix it. First, place the vacuum pump 21 between the two limiting plates 9, then turn on the motor 14. The motor 14 drives the second gear 13 to rotate. The second gear 13 meshes with the first gear 12, and the second gear 13 drives the first gear 12 to rotate. The first gear 12 drives the bidirectional screw 11 to rotate inside the sleeve 10, so that the sleeve 10 moves from inside the slide groove 20 to the outside of the sleeve 10. The sleeve 10 drives the moving plate 7 and the connecting column 8 to move. The moving plate 7 and the connecting column 8 drive the two limiting plates 9 to limit and install the sleeve 10, thus completing the limitation of the vacuum pump 21 at the top of the experimental platform 1.

[0037] Before using the equipment component sleeve 10, it needs to be fixed in place. First, place the component sleeve 10 securely between the two limiting plates 9, then turn on the motor 14. The motor 14 drives the second gear 13 to rotate. Since the teeth of the second gear 13 and the first gear 12 are tightly meshed, the first gear 12 is driven to rotate. The rotating first gear 12 then drives the internal moving component, the bidirectional screw 11, to rotate inside the sleeve 10, causing the sleeve 10 to move outward within the fixed slide groove 20. The movement of the sleeve 10 drives the moving plate 7 and the connecting column 8, ultimately allowing the two limiting plates 9 to complete the limiting installation of the sleeve 10, ensuring that the vacuum pump 21 is securely positioned. Compared with traditional experimental platforms, this platform, through the cooperation between the sleeve 10 and the bidirectional screw 11, facilitates the limiting of the vacuum pump 21 by the limiting plates 9. The design is ingenious, with the threads at both ends rotating in opposite directions. When the bidirectional screw 11 is rotated, the sleeves 10 at both ends move synchronously towards the middle or both ends. This design allows for precise and flexible adjustment of the position of the limiting plate, which can quickly adapt to vacuum pumps 21 of different sizes and shapes. The limiting plate 9 acts directly on the vacuum pump and closely cooperates with the sleeves 10 and the bidirectional screw 11 to achieve precise positioning and can quickly change the fixed position according to experimental needs. When the screw is rotated to the appropriate position, the sleeves drive the limiting plate 9 to tightly clamp the vacuum pump 21, forming a stable mechanical lock, which is more reliable than traditional clamping devices, effectively preventing the pump body from moving or shaking, enhancing experimental safety, and protecting the bidirectional screw 11 from external impacts. In addition, this design greatly improves experimental efficiency and convenience, allowing for quick installation and disassembly of the vacuum pump, simplifying operation, and reducing the difficulty and labor intensity of experimental personnel.

[0038] In some examples, a support frame 22 is fixedly mounted on the top of the experimental platform 1, and the support frame 22 presents four identical shapes.

[0039] Since the support frame 22 has four identical shapes inside the experimental platform 1, it provides stable support for the connecting pipe between the sleeve block 10 and the screw air compressor 2, reducing pipe shaking during use.

[0040] In some examples, a support base 15 is fixedly mounted on the front of the experimental platform 1, and the interior of the support base 15 has a U-shaped form.

[0041] Since the support base 15 is U-shaped on the front of the experimental platform 1, it provides stable support for the motor 14, reduces the shaking of the motor 14 during use, and improves the service life of the motor 14.

[0042] In some examples, the positioning block 16 and the pull rod 17 are paired up, with two sets of movable installations inside the mounting base 4 and the mounting block 5.

[0043] Since the positioning block 16 and the pull rod 17 are paired up, there are two sets of movable installations inside the mounting base 4 and the mounting block 5. Through the cooperation between the positioning block 16 and the pull rod 17, it is easy to install the mounting block 5 inside the mounting base 4, thus ensuring the stability of the screw air compressor 2 during use.

[0044] In some examples, the outer diameter of the mounting block 5 is equal to the inner diameter of the mounting base 4, and the interior of the mounting base 4 has a smooth surface design.

[0045] Because the mounting base 4 has a smooth interior design and the outer diameter of the mounting block 5 is equal to the inner diameter of the mounting base 4, the mounting block 5 can slide and be installed inside, ensuring the installation efficiency of the screw air compressor 2.

[0046] In some examples, a triangular support 25 is fixedly installed on the top of the experimental platform 1, and a reaction vessel 24 is fixedly installed between the two triangular supports 25.

[0047] Since the reactor 24 is fixedly installed between the two triangular supports 25, the triangular supports 25 can provide stable support for the reactor 24, ensuring the stability of the reactor 24 during the experiment and improving the efficiency of the reactor 24.

[0048] In some examples, four stair frames 23 are fixedly installed around the bottom of the experimental platform 1.

[0049] Since four stair frames 23 are set around the bottom of the experimental platform 1, it is convenient for staff to step onto the stair frames 23, and it is convenient for the experimental equipment on the experimental platform 1 to be installed and adjusted in position.

[0050] In some examples, a fixing block 26 is fixedly installed around the outer perimeter of the experimental platform 1, and a positioning hole 27 is provided inside the fixing block 26.

[0051] Workers pass a steel wire rope through the positioning hole 27 and use a crane to slowly raise the steel wire rope. The steel wire rope then drives the fixing block 26 and the experimental platform 1 to rise, making it easier to move the experimental platform 1 in a timely manner.

[0052] In some examples, the screw air compressor 2 has heat dissipation holes 3 inside, and the heat dissipation holes 3 are arranged in a linear array.

[0053] Since the heat dissipation holes 3 are arranged in a linear array inside the screw air compressor 2, it is convenient to dissipate heat from the inside of the screw air compressor 2 in a timely manner, ensuring the temperature stability of the screw air compressor 2 during use and improving the stability of the screw air compressor 2 during the process.

[0054] Working principle and usage process of this utility model:

[0055] First, the operator installs the screw air compressor 2 on top of the mounting block 5. Then, holding the pull rod 17, the operator pulls the positioning block 16 inside the mounting base 4, causing it to press against the spring 19 and pass through the mounting base 4 into the housing 18. Next, holding the push rod 6, the operator aligns the mounting block 5 with the inside of the mounting base 4 and slowly pushes it into the mounting base 4. The mounting block 5 then moves the screw air compressor 2 synchronously. When the mounting block 5 is fully inside the mounting base 4, the operator releases the pull rod 17, and the spring 19 presses against the positioning block 16, causing it to quickly enter the mounting block 5, thus completing the installation of the screw air compressor 2.

[0056] Before using the vacuum pump 21, the operator needs to limit and fix it. First, place the vacuum pump 21 between the two limiting plates 9, then turn on the motor 14. The motor 14 drives the second gear 13 to rotate. The second gear 13 meshes with the first gear 12, and the second gear 13 drives the first gear 12 to rotate. The first gear 12 drives the bidirectional screw 11 to rotate inside the sleeve 10, so that the sleeve 10 moves from inside the slide groove 20 to the outside of the sleeve 10. The sleeve 10 drives the moving plate 7 and the connecting column 8 to move. The moving plate 7 and the connecting column 8 drive the two limiting plates 9 to limit and install the sleeve 10, thus completing the limitation of the vacuum pump 21 at the top of the experimental platform 1.
