[0001] The present invention relates to the technical field of maintenance and repair of wind turbine units, and particularly to a liquid injection and air supplementing pump. Background Art

[0002] During the operation of a wind power generation unit, large components such as generators and gearboxes will generate a large amount of heat. Some units are designed with a water cooling system composed of equipment such as water pumps, valve blocks, expansion tanks, and radiators for heat dissipation. The water cooling system mainly consists of a driving pump, a temperature sensor, a pressure sensor, a storage tank, an air cooler, various valve bodies, and a circulating pipeline, etc. Due to the existence of the water cooling system, it is required to regularly maintain the water cooling system. When the coolant in the water cooling system of the wind power generation unit is insufficient, the cooling capacity of the system decreases, resulting in the unit operating at a limited power, and even causing a fire accident due to excessive temperature and component explosion.

[0003] In actual work, the applicability of existing tools is not strong, so a special device for replenishing the coolant and a special device for the expansion tank are needed.

[0004] Therefore, a liquid injection and air supplementing pump is provided to simultaneously have the functions of supplementing the coolant and replenishing air to the expansion tank, so as to improve the maintenance efficiency of the wind power generation unit. Summary of the Invention

Since the push plate 10 is threadedly sleeved on the surface of the screw, under the drive of the screw, the push plate 10 will push the push plate 10 to move to the right through the connecting plate 12. By changing the area of the cavity on the right side of the block 11, the pressure during air flow is changed. And due to the setting of the rotating plate 9, when the push plate 10 slides to the right, it will press the rotating plate 9. Under the action of the spring 8, good sealing performance will be maintained. The liquid injection pump and the air supplement pump can be used simultaneously, improving the efficiency of liquid injection and air supplement.

[0028] Furthermore, an air supplement pump body 7 is provided inside the main body 6. The air supplement pump body 7 is fixedly connected to a connecting rod 34. The connecting rod 34 penetrates through the push plate 10. Both sides of the push plate 10 are slidably connected to the inner wall of the main body 6.

[0038] It should be noted that by providing the two straight rods 26, the diameter of the straight rod 26 at the position of the upper through hole 35 of the small diameter part of the stepped cylinder is smaller than the aperture of the upper through hole 35 of the small diameter part of the stepped cylinder, leaving enough clearance to prevent the coolant from flowing from the liquid injection space 24 into the capacity chamber 28.

[0039] Further, a through hole 35 is fixedly provided at the bottom of the connecting rod 34. The diameter of the through hole 35 is the same as the diameter of the straight rod 26. At the place where the through hole 35 contacts the bottom of the base 21, an annular sealing ring 29 is fixedly provided. There are two pairs of annular sealing rings 29.

[0040] It should be noted that each nozzle has an annular sealing ring. After the nozzle presses down on the liquid injection hole of the battery cell, the nozzle hole, the inner space of the battery cell and the outside air are kept sealed and isolated, and leakage is prevented during operation.

[0041] Further, two positioning shafts 30 are inserted on the intermediate plate 18. The two positioning shafts 30 penetrate through the capacity adjustment plate 23.
