Description

Technical Field

[0001] This utility model relates to the field of engine protection technology, specifically to an engine protection structure. Background Technology

[0002] Oil extraction infrastructure construction, from preparation to completion, requires the participation of numerous mechanical equipment, such as excavators, loaders, and drilling rigs. Due to the high-intensity operation of these machines, the engine section typically features a high-load diesel engine. To facilitate engine cooling, the equipment includes a pre-installed cooling space and a cooling fan in the engine mounting area. To prevent floating debris from affecting airflow and engine cooling, filter deflectors are added around the cooling space. While these filters effectively intercept debris, they still have shortcomings in practical use. The lack of a flexible cleaning mechanism can lead to filter blockage, obstructing ventilation and affecting engine cooling. Therefore, an engine protection structure is proposed to address these issues. Utility Model Content

The end of the first telescopic rod 13 on the same side is fixedly connected to the side of the side block frame 601.

[0016] Furthermore, to facilitate the sealing and protection of the engine 3 during idle periods, a sealing and shielding mechanism 7 is provided on the top of the cover 2. The sealing and shielding mechanism 7 includes a second servo motor 701, which is fixedly mounted on the top of the cover 2. The output shaft of the second servo motor 701 is connected to a rotating shaft 702 via a coupling, and the other end of the rotating shaft 702 is rotatably connected to the top of the cover 2 via a bracket. A cover plate 703 is attached to the surface of the rotating shaft 702, and an upper filter plate 5 is slidably disposed inside the cover 2. The upper blocking frame 704 is used in conjunction with the upper blocking frame 704. The upper blocking frame 704 consists of a top frame and several inserts.

Both sides of the bottom of the upper blocking frame 704 are connected to L-shaped extrusion plates 707. Both sides of the two side blocking frames 601 are connected to inclined baffles 708 that are used in conjunction with the L-shaped extrusion plates 707 on opposite sides. The top of the inner cavity of the protective cover 2 is connected to the second sleeve 15 on both sides by brackets. The second sleeve 15 is slidably connected to the second telescopic rod 16, and the end of the second telescopic rod 16 is fixedly connected to the side of the upper block 704. A second spring 17 is connected between the second telescopic rod 16 and the second sleeve 15.

[0017] Furthermore, to improve the convenience of dust removal from the upper filter plate 5, the top of the cover 2 is provided with a dust removal mechanism 8 that is used in conjunction with the upper filter plate 5. The dust removal mechanism 8 includes a sliding groove 801. There are two sliding grooves 801, and the two sliding grooves 801 are respectively opened on both sides of the top of the cover 2. A dust pushing plate 802 that is used in conjunction with the upper filter plate 5 is slidably connected between the two sliding grooves 801. A third spring 803 is connected between the dust pushing plate 802 and the sliding groove 801. Several inclined rods 804 that are used in conjunction with the cover plate 703 are connected to the top of the dust pushing plate 802.

[0018] The specific usage steps are as follows: When it is necessary to ventilate and cool the engine 3, start the cooling fan 9. The cooling fan 9 uses the side filter plate 4 as the air inlet and the upper filter plate 5 as the air outlet, thereby exchanging the hot air around the engine 3 with the relatively cool air outside. During wind-powered cooling, two first servo motors 605 are simultaneously activated. The first servo motors 605 drive the reciprocating screw 603 to rotate. The threaded sleeve 606 slides back and forth on the surface of the reciprocating screw 603. The threaded sleeve 606 drives the double-inclined extrusion block 609 and the scraper plate 610 to move through the U-shaped inclined bracket 608. The movement of the double-inclined extrusion block 609 causes its inclined surface to press against the T-shaped plate 602, causing the T-shaped plate 602 to move laterally. The movement of the T-shaped plate 602 drives the side block bracket 601 and the side filter plate 4 to move together. The two scraper plates 610 are moved to clean the side filter plate 4 in the blocked state. The scraped dust is blown away by the dust blowing fan 10 and the air blowing pipe 11, so that the dust on the top of the scraper plate 610 can be blown away. Secondly, since the original positions of the two scraper plates 610 are the upper and lower limit positions of the reciprocating screw 603, the two scraper plates 610 move in opposite directions, so that the two scraper plates 610 clean the side filter plate 4 alternately. When the equipment is idle and the engine 3 needs to be protected, the second servo motor 701 is started. The second servo motor 701 drives the rotating shaft 702 to rotate. The rotating shaft 702 drives the cover plate 703 and the cam 706 to flip. The flipped cover plate 703 will cover the top of the upper filter plate 5. When the cam 706 rotates, it will lift the Z-shaped frame 705, causing the upper blocking frame 704 to drive the L-shaped extrusion plate 707 to rise. The L-shaped extrusion plate 707 rises and extrudes the inclined baffle 708, causing the side blocking frame 601 to cooperate with the side filter plate 4 for sealing. When the upper blocking frame 704 rises, it simultaneously engages with the upper filter plate 5 and pushes out the ash stored in the holes of the upper filter plate 5. As the upper blocking frame 704 engages with the upper filter plate 5, during the subsequent flipping process, the cover plate 703 will squeeze the inclined rod 804, causing the inclined rod 804 to drive the ash pushing plate 802 to perform a one-time ash cleaning treatment on the top of the upper filter plate 5.
