[0027] Example 1

[0028] Please see Figures 1-5 An embodiment of this utility model provides: an ethylene cryogenic liquid pump, including a shock-absorbing box 1 and a support plate 4. The support plate 4 is provided above the shock-absorbing box 1 and is slidably connected to the shock-absorbing box 1. A liquid pump body 3 is installed on the top of the support plate 4. An integrated plate 5 is installed on the top of the support plate 4 on both sides of the liquid pump body 3. A servo motor 6 is installed on one side of the integrated plate 5 and plays a power driving role. A rotating disk 17 is installed on the other side of the integrated plate 5 and is connected to the output end of the servo motor 6. Support columns 20 are installed on the side walls of the integrated plate 5 on both sides of the rotating disk 17. A toggle column 18 is installed on the side walls of the rotating disk 17. A swing frame 19 is provided on the outside of the rotating disk 17 and is slidably connected to the toggle column 18. A limit frame 12 is installed on both sides of the swing frame 19 and is slidably connected to the support column 20. A protective cover 2 is provided above the support plate 4.

[0029] The liquid ethylene is cooled and kept in a liquid state by the compressor inside the liquid pump body 3, and then pumped and delivered. When the liquid pump body 3 is working, the internal compressor generates heat. To prevent high temperatures from affecting its efficiency, the cooling fan 14 is turned on to blow air and dissipate heat from the liquid pump body 3. The holes on the outer wall of the protective cover 2 serve as ventilation. Simultaneously, the servo motor 6 is turned on, driving the rotating disk 17 to rotate. The rotating disk 17 then drives the actuating column 18 to rotate. With the sliding engagement of the actuating column 18 and the swing frame 19, and the limit frame 12 and the support column 2... Under the sliding engagement of 0, the actuating column 18 drives the swing frame 19 and the limiting frame 12 to move laterally and reciprocally. The swing frame 19 drives the limiting rack 16 to move. Under the mutual meshing of the limiting gear 15 and the limiting rack 16, the limiting gear 15 provides limiting support for the limiting rack 16. Thus, the limiting frame 12 drives the moving plate 13 and the cooling fan 14 to move back and forth. The cooling fan 14 moves back and forth to blow air evenly on the liquid pump body 3, which improves the heat dissipation effect and ensures the normal operation of the liquid pump body 3. It realizes convenient reciprocating movement and uniform air blowing for heat dissipation, and improves the air blowing heat dissipation effect.

[0030] Each swing frame 19 has a limiting rack 16 installed at its top end, and the limiting rack 16 is fixedly connected to the swing frame 19.

[0031] Limiting gears 15 are movably installed on the side wall of the integrated plate 5 above the limiting rack 16, and the limiting gears 15 and the limiting rack 16 mesh with each other.

[0032] The side walls of the limit frame 12 are all equipped with movable plates 13, and the side walls of the movable plates 13 are all equipped with cooling fans 14. The bottom end of the support plate 4 is symmetrically provided with two sets of linkage arms 10, and the top end of each linkage arm 10 is provided with an upper movable shaft 11. The linkage arm 10 is slidably connected to the support plate 4 through the upper movable shaft 11.

[0033] Each end of the linkage arm 10 away from the bearing plate 4 is provided with a sliding block 8, and the sliding block 8 is slidably connected to the bearing plate 4. Each side wall of the sliding block 8 is equipped with a shock absorber 7, and the other end of the shock absorber 7 is fixedly connected to the bearing plate 4.

[0034] The top of each sliding block 8 is equipped with a lower movable shaft 9, and the linkage arm 10 is movably connected to the sliding block 8 through the lower movable shaft 9;

[0035] When the liquid pump body 3 is working, it will vibrate, and the vibration amplitude is up and down. The liquid pump body 3 drives the bearing plate 4 to move up and down inside the shock absorber 1. The bearing plate 4 drives the linkage arm 10 to rotate through the upper movable shaft 11. Under the sliding cooperation between the sliding block 8 and the shock absorber 1, the linkage arm 10 drives the sliding block 8 to move through the lower movable shaft 9, and makes the two sets of sliding blocks 8 move away from each other. The sliding block 8 squeezes the shock absorber 7, and the shock absorber 7 cancels the squeezing force of the sliding block 8, thereby canceling the vibration of the bearing plate 4, and thus ensuring the stability of the liquid pump body 3 when it is working.

[0036] Work steps

[0037] The liquid ethylene is cooled and kept in a liquid state by the compressor inside the liquid pump body 3, and then pumped and delivered. When the liquid pump body 3 is working, the internal compressor generates heat. To prevent high temperatures from affecting its efficiency, a cooling fan 14 blows air to cool the liquid pump body 3. The servo motor 6 drives the rotating disk 17 to rotate, which in turn drives the actuating column 18 to rotate. With the sliding engagement of the actuating column 18 and the swing frame 19, and the sliding engagement of the limiting frame 12 and the support column 20, the actuating column 18 drives the swing frame 19 and the limiting frame 12 to move laterally back and forth. The swing frame 19 drives the limiting rack 16 to move, and the limiting gear 15 provides limiting support for the limiting rack 16. This, in turn, causes the limiting frame 12 to drive the moving plate 13 and the cooling fan 14 to move back and forth. The fan 14 reciprocates and blows air evenly onto the liquid pump body 3, improving heat dissipation and ensuring the normal operation of the liquid pump body 3. When the liquid pump body 3 is working, it will vibrate, with the vibration amplitude being up and down. The liquid pump body 3 drives the support plate 4 to move up and down inside the shock absorber box 1. The support plate 4 drives the linkage arm 10 to rotate through the upper movable shaft 11. Under the sliding cooperation between the sliding block 8 and the shock absorber box 1, the linkage arm 10 drives the sliding block 8 to move through the lower movable shaft 9, and the two sets of sliding blocks 8 move away from each other. The sliding block 8 squeezes the shock absorber 7, and the shock absorber 7 cancels out the squeezing force of the sliding block 8, thereby canceling out the vibration of the support plate 4, and thus ensuring the stability of the liquid pump body 3 during operation. The above is the complete usage of the ethylene cryogenic liquid pump.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
