Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] The vacuum pump cooling device disclosed in this invention is mainly used in scenarios where the vacuum pump generates a large amount of heat during operation, and the heat is difficult to dissipate quickly, resulting in a continuous rise in the vacuum pump temperature.

[0019] Reference Figures 1-8 A vacuum pump 4 cooling device, comprising: Cooling box 1, with a vacuum pump 4 installed inside; The air outlet 5 is located at the top of the cooling box 1 and is connected to the interior of the cooling box 1. The air inlet 6 is located at the top of the cooling box 1 and is connected to the interior of the cooling box 1. The base frame 2 is fixedly connected to the bottom end of the cooling box 1; Cooling plate 8 is installed inside cooling box 1. A rectangular hole is opened at the bottom end of the base frame 2, and the bottom end of cooling plate 8 is fixedly connected to the top end of the rectangular hole. The annular spray cooling assembly 15 is disposed inside the cooling box 1. The annular spray cooling assembly 15 is used to cool the vacuum pump 4 when the vacuum pump 4 is working. The swing-type extended-area cooling component 10 is located on the side of the vacuum pump 4 away from the annular spray cooling component 15. The swing-type extended-area cooling component 10 is used to divert the air temperature inside the cooling chamber 1 when the vacuum pump 4 is working.

[0020] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 In a preferred embodiment, the annular spray cooling assembly 15 includes: The ring gear plate 1505 is fixedly connected to one side of the interior of the cooling box 1; Two fans 1509 are both located on the side of the ring gear plate 1505 near the vacuum pump 4. The fans 1509 are used to cool the vacuum pump 4 during operation. Two atomizers 1513 are both located between the fans 1509. The atomizers 1513 are used to spray atomized gas for atomization cooling.

[0021] In this invention, the annular spray cooling assembly 15 further includes: The drive motor 1502 is located on the side of the ring gear plate 1505 away from the vacuum pump 4, and the power output shaft of the drive motor 1502 is connected to the rotating rod 1503 through a coupling. The rotating plate frame 1504 is fixedly connected to the outside of the rotating rod 1503, and the rotating plate frame 1504 is located on the side of the ring gear plate 1505 away from the vacuum pump 4. Two rotating gears 1507 are disposed between the ring gear plate 1505, and the rotating gears 1507 and the ring gear mesh with each other through tooth grooves.

[0022] In this invention, a motor frame 1501 is fixedly connected to one side of the interior of the cooling box 1. The inner side of the motor frame 1501 is fixedly connected to the outer side of the drive motor 1502. Connecting rods 1506 are fixedly connected to both ends of the rotating plate frame 1504 near the fan 1509. The outer sides of the connecting rods 1506 are movably connected to the inner side of the rotating gear 1507. Grooves are provided at both ends of the rotating plate frame 1504. Two connecting plates 1510 are fixedly connected inside the grooves. A round rod 1511 is fixedly connected to the opposite side of the connecting plate 1510. A connecting seat 1512 is fixedly connected to the outer side of the round rod 1511. The side of the connecting seat 1512 away from the drive motor 1502 is fixedly connected to one end of the atomizer 1513. A fixing frame 1508 is fixedly connected to the bottom end of the rotating gear 1507. The front end of the fixing frame 1508 is fixedly connected to one side of the fan 1509.

[0023] Specifically, when the vacuum pump 4 operates, the drive motor 1502 starts, driving the rotating rod 1503 to rotate. The rotation of the rotating rod 1503 directly pulls the rotating frame 1504 to begin circular motion around the center of the ring gear plate 1505. When the rotating frame 1504 moves, the connecting rod 1506 moves accordingly. The outer side of the connecting rod 1506 is movably connected to the inner side of the rotating gear 1507. Under the traction of the circular motion of the rotating frame 1504, the rotating gear 1507 revolves around the center of the ring gear plate 1505 along with the rotating frame 1504. On the other hand, because the rotating gear 1507 meshes with the tooth groove of the ring gear plate 1505, it will rotate on its own during the revolution. The bottom fixed frame 1508 of the rotating gear 1507 moves synchronously, thereby driving the fan 1509 to both perform circular motion around the center of the ring gear plate 1505 and rotate on its own due to the rotation of the rotating gear 1507, making the air blowing range of the fan 1509 more comprehensive. The connecting plate 1510, round rod 1511, and connecting seat 1512 in the grooves at both ends, along with the circumferential motion of the rotating plate frame 1504, drive the atomizer 1513 to move synchronously, causing the atomizer 1513 to also move in a circular motion around the center of the ring gear plate 1505. During the motion, the atomizer 1513 starts and sprays atomized water mist. This water mist, as a cooling medium, is blown and diffused by the synchronously moving fan 1509. The fan 1509 blows and diffuses the water mist sprayed by the atomizer 1513 toward the direction closer to the vacuum pump 4, forming a dynamic atomized cooling layer. As the fan 1509 and the atomizer 1513 continuously move in a circular motion around the ring gear plate 1505, different parts of the outer side of the vacuum pump 4 can be covered by atomized water mist. Combined with the wind force of the fan 1509 to accelerate heat exchange, the heat generated by the operation of the vacuum pump 4 is continuously removed, achieving effective cooling of the outer side of the vacuum pump 4 and ensuring that the vacuum pump 4 continues to work stably in a suitable temperature environment.

[0024] In specific application scenarios, the water mist sprayed by the atomizer 1513 is dispersed by the fan 1509, increasing the contact area with the vacuum pump 4. The wind force can also accelerate heat exchange, allowing the water mist and wind force to cover all angles of the outer side of the vacuum pump 4, avoiding local overheating, making the cooling more uniform, and protecting the vacuum pump 4.

[0025] It should be noted that this ring-shaped structure can provide all-round cooling regardless of the position of the vacuum pump 4 inside the cooling box 1. It is adaptable to vacuum pumps 4 of different sizes and installation positions, and has strong versatility. It can also stably cool down when the vacuum pump 4 is working under continuous high load, ensuring reliable operation of the equipment.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 In a preferred embodiment, the oscillating extended-range cooling assembly 10 includes: The upper plate 1001 has a rectangular perforation on the side of the cooling box 1 away from the annular spray cooling component 15, and the top of the upper plate 1001 is fixedly connected to the top of the inner side of the rectangular perforation. The lower plate 1002 is fixedly connected to the bottom inner side of the rectangular perforation; Multiple diffuser plates 1004 are located between the upper plate 1001 and the lower plate 1002. The diffuser plates 1004 are used to exhaust the hot air inside the cooling box 1 and diffuse the cold air.

[0027] In this invention, the swing-type extended-range cooling assembly 10 further includes: An electric telescopic rod 1011 is installed above the upper plate 1001 and is located inside the cooling box 1. Multiple sliding seats 1007 are located above the diffuser plate 1004. The upper plate 1001 is provided with a sliding groove, and the sliding seats 1007 are slidably connected to the inside of the sliding groove. The sliding plate 1009 is positioned above the diffuser plate 1004.

[0028] In this invention, a plurality of retaining rods 1003 are fixedly connected to the bottom end of the upper plate 1001, and the bottom ends of the retaining rods 1003 are all fixedly connected to the top end of the lower plate 1002. The interior of the diffuser plate 1004 is rotatably connected to the outside of the retaining rods 1003. A movable rod 1005 is fixedly connected to the bottom end of each diffuser plate 1004, and a bearing 1006 is fixedly connected to the outside of each movable rod 1005. The bottom end of each bearing 1006 is fixedly connected to the top end of the sliding seat 1007. Multiple lower rods 1008 are fixedly connected to the bottom of 1007. The outer side of each lower rod 1008 is fixedly connected to the outer side of the sliding plate 1009. A fixing plate 1010 is fixedly connected to the side of the sliding plate 1009 near the electric telescopic rod 1011. One side of the fixing plate 1010 is fixedly connected to the telescopic end of the electric telescopic rod 1011. A ring frame 1012 is fixedly connected to the outer side of the electric telescopic rod 1011. One end of the ring frame 1012 is fixedly connected to the inside of the cooling box 1.

[0029] Specifically, when the vacuum pump 4 operates, the electric telescopic rod 1011 starts, and the telescopic end of the electric telescopic rod 1011 performs a reciprocating linear motion. This motion, via the fixed plate 1010, drives the sliding plate 1009 to move synchronously. During this motion, the sliding plate 1009, through the connection between the lower rod 1008 and the sliding seat 1007, pulls the sliding seat 1007 to slide back and forth within the groove of the upper plate 1001. As the sliding seat 1007 slides, the movable rod 1005, connected at its top end via the bearing 1006, moves accordingly. Since the bottom end of the diffuser plate 1004 is fixed to the movable rod 1005, and the diffuser plate 1004 is rotatably connected to the outside of the fixed rod 1003, the movement of the movable rod 1005 causes the diffuser plate 1004 to rotate around the fixed rod 1003. The back-and-forth oscillation of the diffuser plate 1004 continuously changes its relative angle and ventilation gap with the internal space of the cooling box 1. When the diffuser plate 1004 oscillates, on the one hand, it guides the hot air generated near the vacuum pump 4 to the outside of the cooling box 1 through the channel formed by the oscillation of the diffuser plate 1004; on the other hand, it allows the cold air inside the cooling box 1 (which may come from the low-temperature airflow after the action of the cooling medium such as the annular spray cooling component 15) to diffuse more evenly inside the cooling box 1 with the airflow disturbance generated by the oscillation of the diffuser plate 1004, filling the space after the hot air is discharged, realizing the effective diversion and diffusion of the internal temperature of the cooling box 1, helping to maintain a suitable temperature environment inside the box, and ensuring the stable operation of equipment such as the vacuum pump 4.

[0030] In specific application scenarios, the diffuser plate 1004 swings back and forth, actively disturbing the airflow inside the cooling box 1, accelerating the discharge of hot air and the diffusion of cold air, making the airflow circulation inside the box smoother, avoiding the accumulation of hot air, quickly balancing the temperature inside the box, and improving the overall cooling effect.

[0031] It should be noted that by changing the angle of the diffuser plate 1004 and the air gap, the airflow direction and velocity can be flexibly adjusted, which can accurately adapt to the heat dissipation requirements of the vacuum pump 4 under different working loads, stably control the temperature inside the chamber within a suitable range, and ensure the reliable operation of the equipment.

[0032] Reference Figures 1-4 In a preferred embodiment, a pump body mounting bracket 3 is fixedly connected to the top of the cooling plate 8. The pump body mounting bracket 3 is fixedly connected to the outside of the vacuum pump 4. A pusher 7 is fixedly connected to one side of the cooling box 1. Multiple base plates 9 are fixedly connected to the bottom of the base frame 2. Multiple universal frames 11 are fixedly connected to the bottom of the base plates 9. Fixed rods 12 are fixedly connected to the inside of each universal frame 11. Pulleys 13 are rotatably connected to the outside of each fixed rod 12. Vibration damping springs 14 are fixedly connected to both sides of each pulley 13. The opposite sides of each vibration damping spring 14 are fixedly connected to both sides inside the universal frame 11.

[0033] A method of using a vacuum pump 4 cooling device, comprising the following steps: Step 1: The cooling box 1 uses the pulley 13 at the bottom and its vibration damping structure to move the vacuum pump 4 to the working area to prepare for subsequent work. Step 2: Before vacuum pump 4 starts working, connect the pipeline. When working, drive motor 1502 drives rotating plate frame 1504 to rotate via rotating rod 1503. Rotating plate frame 1504 drives fan 1509 and atomizer 1513 to move. Atomizer 1513 sprays water mist, and fan 1509 diffuses the water mist. Together with cooling plate 8, vacuum pump 4 is cooled in multiple directions. Step 3: The electric telescopic rod 1011 is started, and the sliding plate 1009 is driven to move back and forth through the fixed plate 1010. The sliding plate 1009 drives the sliding seat 1007 to slide in the slide groove through the lower rod 1008, thereby causing the diffuser plate 1004 to swing back and forth around the fixed rod 1003, so as to realize the discharge of hot air and the diffusion of cold air in the cooling box 1, and assist in cooling.
