Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof lubrication pumps, and more specifically, to an explosion-proof lubrication pump. Background Art

[0002] During the operation of wind turbines, the wind power lubrication system needs to inject grease regularly and quantitatively to add grease to various bearings and other operating parts to ensure the safe, stable and efficient operation of the unit equipment. The lubrication pump, as part of the wind power lubrication system, also needs to be regularly filled with grease.

[0003] During the actual operation of existing lubrication pumps, the operator's attention may be distracted by other things or objects. Since the grease is injected quickly, once the operator's attention is diverted for a short while, the grease may overflow. At this time, the pressure in the lubrication pump tank cannot be quickly released, which can easily cause the tank to burst, thereby damaging the equipment or causing a safety accident.

[0004] After searching, a Chinese patent with announcement number CN220453384U discloses an explosion-proof lubrication pump. When the grease is filled in excess, the grease will push the piston beyond the first explosion-proof pressure relief hole. At this time, the excess grease can pass through the first explosion-proof pressure relief hole into the guide hole, and finally be discharged out of the oil tank through the waterproof breathable valve, so that the pressure in the oil tank will never exceed the bearing limit of the oil tank material, thereby avoiding the problem of excessive pressure causing the oil tank to burst or causing harm to on-site workers.

[0005] However, when the above-mentioned lubrication pump is actually used, when the pressure inside the lubrication pump is high, the pressure inside the lubrication pump may cause excessive leakage of the internal lubricating fluid from the pressure relief hole, resulting in insufficient filling of the lubricating fluid inside the lubrication pump.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0040] The embodiment of the present application discloses an explosion-proof lubrication pump, specifically comprising a lubrication pump body 1, a pump cover 2 is fixedly connected to the left side of the lubrication pump body 1, a fixing frame 3 is fixedly connected to the right side of the pump cover 2, a limiting rod 4 is fixedly connected to the right side of the fixing frame 3, a plunger pump body assembly 27 is fixedly connected to the left side of the surface of the limiting rod 4, and a pressure relief mechanism is movably connected inside the lubrication pump body 1;

[0041] The pressure relief mechanism includes a slide plate 5, a sealing strip 6 is fixedly connected to the outside of the slide plate 5, oil outlet pipes 7 are fixedly connected to the front and rear sides of the lubrication pump body 1, the front ends of the two oil outlet pipes 7 are fixedly connected to rotating rods 8, the two oil outlet pipes 7 are fixedly connected to the inside of the gear lever 9, the two rotating rods 8 are movably connected to the outside of the two rotating rods 8, the two sealing blocks 10 are movably connected to the inside of the first springs 11, the tops of the two first springs 11 are fixedly connected to pop-up blocks 12, and the left sides of the two sealing blocks 10 are fixedly connected. When the two sealing blocks 10 are opened, the two oil outlet pipes 7 discharge excess grease from the inside of the lubrication pump body 1 and collect it through the oil collecting box 18. The two sealing blocks 10 can be quickly opened and closed according to the movement of the slide plate 5.

[0042] Reference Figure 2 As shown, specifically, a sealing ring 14 is fixedly connected inside the slide plate 5, a first baffle ring 15 is fixedly connected to the right side of the slide plate 5, a second spring 16 is fixedly connected to the right side of the first baffle ring 15, a second baffle ring 17 is fixedly connected to the right end of the second spring 16, an oil receiving box 18 is fixedly connected to the bottom of the lubrication pump body 1, and a movable plate 19 is movably connected to the right side of the oil receiving box 18, which can be moved according to the amount of grease inside the lubrication pump body 1 to facilitate the discharge and collection of excess grease.

[0043] Reference Figure 3 As shown, specifically, an oil inlet pipe 20 is fixedly connected to the left side of the lubrication pump body 1, and pop-up balls 21 are movably connected to both sides of the inside of the oil inlet pipe 20, so as to quickly fix the connected pipe.

[0044] Reference Figure 3 As shown, specifically, a movable ring 22 is movably connected to the outer side of the oil inlet pipe 20, two pull rods 23 are fixedly connected to the bottom of the movable ring 22, a pull plate 24 is fixedly connected to the outer sides of the two pull rods 23, two third springs 25 are fixedly connected to the bottom of the pull plate 24, and a bottom ring 26 is fixedly connected to the bottom of the two third springs 25, which assists the movement of the movable ring 22 so that the movable ring 22 can quickly block the pop-up ball 21.

[0045] The working principle of the utility model is as follows: when filling the lubrication pump with grease, first press the tube pull plate 24 downward along the direction of the third spring 25, so that the pull plate 24 drives the two pull rods 23 and the movable ring 22 on the top to move downward. During the downward movement of the pull rod 23, the two pop-up balls 21 on the outer side of the oil inlet pipe 20 are squeezed inward, so that the two pull plates 24 are collected into the interior of the oil inlet pipe 20, and then the pipeline is connected to the outer side of the pull plate 24, and then the pull plate 24 is released so that the pull plate 24 is pushed by the third spring 25, and the movable ring 22 releases the two pop-up balls 21 from the interior of the oil inlet pipe 20 again, and the two pop-up balls 21 quickly clamp the inserted pipeline, so that the pipeline remains stable when conveying grease through the oil inlet pipe 20, and then the grease enters the interior of the lubrication pump body 1 through the pump cover 2 and the fixing frame 3. When the grease is about to be filled inside the lubrication pump body 1, the grease pushes the slide plate 5 to slide along the limit rod 4 to the right side of the lubrication pump body 1. When the slide plate 5 and the sealing strip 6 are pushed to the position of the two oil outlet pipes 7 by the grease, the block 13 on the outside of the two sealing blocks 10 is pushed by the sealing strip 6 on the outside of the slide plate 5, so that the two sealing blocks 10 can rotate around the rotating rod 8, so that an opening is formed between the two sealing blocks 10 and the oil outlet pipe 7, so that excess grease falls from the two oil outlet pipes 7 into the inside of the oil receiving box 18. The grease inside the oil receiving box 18 can be quickly cleaned through the movable plate 19. When the grease pressure inside the lubrication pump body 1 becomes smaller, the slide plate 5, pushed by the second spring 16, passes through the two sealing blocks 10 again and seals the two sealing blocks 10 and the oil outlet pipe 7 again.
