Description

Technical Field

[0001] The utility model relates to the technical field of electric grease guns, in particular to an electric grease gun for preventing residual wind power generation. Background Art

[0002] Wind turbines all use the circulation of wind to drive the blades to rotate, and then generate electricity through the rotation of the blades. When the blades rotate, they will rub against the wind turbine. In order to reduce friction, you need to use an electric grease gun to squeeze grease into the connection between the blades and the device to achieve the lubrication effect;

[0003] When applying grease with an existing electric grease gun, the grease may overflow from the gap between the push plate and the outer shell due to the grease being squeezed by the push plate, and then the grease may be adsorbed on the inner wall of the outer shell, resulting in insufficient use of the grease.

[0004] To address the above-mentioned drawbacks, a grease gun with publication number CN108468937A is disclosed. A sealing ring protrusion and a cylindrical plug body are integrated into a structure. The sealing ring protrusion is in close contact with the inner wall of the cylindrical barrel, and the sealing ring protrusion can effectively remove the grease on the inner wall of the cylindrical barrel. A ceramic heating layer is used as the heating layer, and the heating layer is bonded to the outer wall of the cylindrical barrel, which can effectively prevent the grease from solidifying and affecting the pushing out of the grease. A universal elbow is used as the connecting piece, which facilitates adjustment of the position of the magnifying glass, thereby facilitating magnification of the position to be filled with grease, thereby improving the accuracy of grease filling. The air guide port and the air vent are connected, and there are two air guide ports, which facilitates deflation and thus facilitates the pushing out of the grease.

[0005] In actual use of the above device, although the sealing ring is used to prevent butter residue, the sealing ring will age after long-term use, and the effect of the sealing ring in cleaning butter will decrease, so butter will remain on the inner wall of the cylindrical barrel.

[0006] Therefore, we have proposed an electric grease gun for wind power generation to prevent residual grease and can solve the above problems well. Utility Model Content

[0033] refer to Figures 1 to 4 , inject the butter into the storage bin 3, and the battery compartment 2 can power the controller 1, so that the controller 1 can control the butter inside the storage bin 3 to be injected into the wind turbine through the oil nozzle 4, and the reduction of butter in the storage bin 3 will drive the push rod 5 to move. In order to prevent the butter from overflowing, by pushing the push rod 9, the push rod 9 can be moved to extend into the interior of the air bin 8, and then the air inside the air bin 8 is squeezed and transported to the interior of the scraper 6 through the air pipe 7, so that the scraper 6 can be expanded, and then the gap between the push rod 5 and the storage bin 3 can be eliminated through the expansion, so that the scraper 6 can not only play a sealing role during movement, but also can scrape off the butter adsorbed on the inner wall of the storage bin 3, thereby preventing the butter from being adsorbed on the inner wall of the storage bin 3 and causing residue, thereby improving the use effect;

[0034] Embodiment 2: The present invention solves the problem that the push rod 9 in embodiment 1 is not stable enough. The engagement of the clamping block 12 with the clamping slot 13 can improve the stability of the push rod 9.

[0035] A slider 10 is fixed to the right end of the push rod 9, and the right end of the slider 10 is connected to a first spring 11, and the right end of the first spring 11 is connected to the inside of the push rod 5. The right end of the push rod 9 is slidably connected to a clamping block 12, and the left side of the outer end of the clamping block 12 is arranged in an arc shape. The outer end of the clamping block 12 extends into the interior of the clamping slot 13 to form a clamping mechanism, and the clamping slots 13 are evenly spaced inside the push rod 5. The inner end of the clamping block 12 is connected to a second spring 14, and the second spring 14 is installed inside the push rod 9;

[0036] refer to Figures 1 to 6 , the push rod 5 will drive the card block 12 to move during the movement, and then the card block 12 will be squeezed with the card slot 13, so that the card block 12 is squeezed to move toward the inside of the push rod 9, and then the card block 12 moves out of the engagement with the card slot 13, and the movement of the card block 12 will squeeze the second spring 14, and then the second spring 14 is compressed, and the movement of the push rod 9 will drive the first spring 11 to stretch through the slider 10, and then the first spring 11 can be stressed, and then after the push rod 9 moves to the position, the force of the second spring 14 pushes the card block 12 into the interior of the card slot 13 to form an engagement, and then the position of the push rod 9 can be fixed, thereby improving the stability of the scraper 6;

[0037] Embodiment 3: The present invention solves the problem that the push rod 9 in the second embodiment is not easy to reset. The push rod 9 can be easily reset by moving the pull rope 15.

[0038] The inner end of the block 12 is connected to a pull rope 15, and the right end of the pull rope 15 passes through the second spring 14 and extends into the interior of the push rod 9 to form a sliding mechanism. The bend of the left end of the pull rope 15 is fitted with a roller 16, and the roller 16 is connected to the interior of the push rod 9 through a bearing.

[0039] refer to Figures 1 to 6 When butter needs to be refilled, the storage bin 3 is removed from the controller 1, and the negative pressure in the storage bin 3 is eliminated. Then, the pull rope 15 is pulled, so that the pull rope 15 moves through the roller 16 to drive the block 12 to move, and then the block 12 will be disengaged from the engagement with the slot 13, and then the slider 10 is pulled to reset by the force of the first spring 11, so that the slider 10 moves and drives the push rod 9 to reset, and then the push rod 9 can form a negative pressure in the gas bin 8, so that the negative pressure can transport the gas in the scraper 6 to the inside of the gas bin 8 for storage through the air pipe 7, thereby reducing the fit between the scraper 6 and the storage bin 3, and then the push rod 5 is pulled in the opposite direction, so that the push rod 5 can be reset.

[0040] Working principle: When using this electric grease gun for wind power generation to prevent residual, first, refer to Figures 1 to 4, butter is injected into the storage bin 3, and the battery compartment 2 can power the controller 1. The reduction of butter in the storage bin 3 will drive the push rod 5 to move. In order to prevent butter from overflowing, the push rod 9 is pushed so that the push rod 9 can move and extend into the interior of the air bin 8. Then, the gap between the push rod 5 and the storage bin 3 can be eliminated through expansion, so that the scraper 6 can not only play a sealing role during movement, but also scrape off the butter adsorbed on the inner wall of the storage bin 3, thereby preventing the butter from being adsorbed on the inner wall of the storage bin 3 and causing residue, thereby improving the use effect;

[0041] refer to Figures 1 to 6 , the push rod 5 will drive the card block 12 to move during the movement, and then the card block 12 will be squeezed with the card slot 13, and then the card block 12 will be out of engagement with the card slot 13, and the movement of the card block 12 will squeeze the second spring 14, and then the second spring 14 will be compressed. Then, after the push rod 9 moves to the position, the card block 12 is pushed into the interior of the card slot 13 by the force of the second spring 14 to form an engagement, and then the position of the push rod 9 can be fixed, thereby improving the stability of the scraper 6.

[0042] refer to Figures 1 to 6 When butter needs to be refilled, the storage bin 3 is removed from the controller 1, and the negative pressure in the storage bin 3 is eliminated. Then, the pull rope 15 is pulled, and the block 12 is disengaged from the card slot 13. Then, the slider 10 is pulled back by the force of the first spring 11, and the push rod 9 is able to form a negative pressure in the air bin 8, thereby reducing the fit between the scraper 6 and the storage bin 3. Then, the push rod 5 is pulled in the opposite direction, so that the push rod 5 can be reset.
