Description

Technical Field

[0001] The invention relates to the technical field of diesel generator sets, and in particular to a heat dissipation and dust prevention mechanism for a diesel generator set. Background Art

[0002] A diesel generator set is a complex power generation device that uses a diesel engine as its power source and converts the chemical energy of diesel into electrical energy through a series of mechanical and electrical components.

[0003] Since a diesel generator set generates electricity by a series of devices working together, a large amount of heat will be generated during the working process, so the heat dissipation structure of the diesel generator set is generally installed in the diesel generator set for use. For example, a heat dissipation mechanism for a diesel generator set with the publication number CN111946440A includes a heat dissipation main board, a coolant inlet pipe is fixedly arranged on the left end surface of the heat dissipation main board near the upper side, a coolant outlet pipe is fixedly arranged on the right end surface of the heat dissipation main board near the lower side, a shield body is installed on the front end surface of the heat dissipation main board, side shield plates are arranged on both sides of the shield body, a front shield plate is arranged on the front end surface of the side shield plate, and a restraining bottom plate is arranged at the lower end of the heat dissipation main board.

[0004] The heat dissipation structure of this diesel generator set has a filter screen on the surface of the diesel generator set. During the heat dissipation process, the filter screen filters the dust and diesel stains generated by the diesel generator set. This heat dissipation mechanism needs to be removed from the top surface of the diesel generator set. During the removal process, the dust attached to the filter screen surface may fall off due to vibration. After removal, the dust will fall onto the exposed surface of the diesel generator set. Therefore, the screen surface needs to be cleaned before removal, but the cleaning of the fixed filter screen has limitations and limits the position of the external cleaning tools.

Mounting brackets 22 are provided on both sides of the bottom surface of the top plate 21 of the dust cover structure 2. Two snap-fit ​​blocks 211 are fixedly connected to one side of the mounting brackets 22 on both sides close to the heat sink 11. The position of the snap-fit ​​block 211 is adapted to the position of the snap-fit ​​groove 12 and the snap-fit ​​base 13. The snap-fit ​​block 211 is in a T-shape. The snap-fit ​​block 211 can be inserted into the snap-fit ​​groove 12 and the snap-fit ​​base 13 for fixing. Filters 23 are provided on the surfaces of the mounting brackets 22 on both sides. Lifting rods 24 are slidably provided on the upper and lower surfaces of the top plate 21. The bottom end of the lifting rod 24 extends downward along the vertical direction. The lifting rod 24 is located on one side of the mounting bracket 22. A plurality of rotating seats are provided on the surface of the mounting bracket 22. The plurality of rotating seats are provided at equal distances along the vertical straight line direction. A transmission rod 25 is rotatably arranged in each rotating seat, and each transmission rod 25 passes through a lifting rod 24, and the transmission rod 25 is rotatably connected to the lifting rod 24. Elastic abutment heads 26 are fixedly connected to the opposite sides of the transmission rods 25 on both sides. The bottom end of the transmission rod 25 extends to the bottom of the mounting bracket 22. Two transmission handles 27 are slidably arranged on the top surface of the top plate 21, and the transmission handles 27 are located on the outside of the two lifting rods 24. Two mounting grooves 28 are provided inside the top plate 21, and the mounting grooves 28 are located between the lifting rods 24 and the transmission handles 27.

[0035] The dust cover structure 2 is placed on a specific collection structure 3 for installation. Two switch slots 35 are provided on the top surface of the bottom plate 31 of the collection structure 3, and two mechanical switches are provided on the bottom surface of the switch slots 35. The bottom ends of the two lifting rods 24 of the filter 23 structure can be inserted into the switch slots 35 for positioning. An electrostatic generation bar 32 is fixedly connected to the top surface of the bottom plate 31. When the dust cover structure 2 is installed on the top surface of the bottom plate 31, the electrostatic generation bar 32 is arranged around the dust cover structure 2 on three sides, and the mechanical switch inside the switch slot 35 is electrically connected to the electrostatic generation bar 32. An outer collection slot 33 and an inner collection slot 34 are provided on the top surface of the bottom plate 31. The outer collection slot 33 and the inner collection slot 34 are respectively located on both sides of the electrostatic generation bar 32. The bottom surfaces of the outer collection slot and the inner collection slot 34 are arranged to be inclined upward close to the direction of the electrostatic generation bar 32.

[0036] When using this heat dissipation and dust prevention mechanism for a diesel generator set, place the heat dissipation structure 1 on one side of the working diesel generator set so that the front heat dissipation fins 16 on the surface of the heat dissipation box 11 are in contact with the surface of the diesel generator set. Then inject coolant into the water inlet 14, at which time the drain port 15 switch is closed, and the inside of the heat dissipation box 11 is filled with coolant. The coolant fills the cooling chamber 18 to cool the front heat dissipation fins 16 and the rear heat dissipation fins 17. When the diesel generator set is working, the low-temperature front heat dissipation fins 16 are in direct contact with the surface of the diesel generator set, thereby cooling it. The temperature of the front heat dissipation fins 16 increases due to the heat, which increases the temperature of the coolant in the cooling chamber 18. The coolant is indirectly transferred to the rear heat dissipation fins 17, and the rear heat dissipation fins 17 are directly exposed to the air to dissipate the coolant. The middle heat insulation plate 19 prevents the high-temperature coolant from the front heat dissipation fins 16 from being directly transferred to the rear heat dissipation fins 17, thereby extending the cooling time of the coolant.

[0037] A collecting structure 3 is provided under the diesel generator set, and the dust cover structure 2 is covered from the top surface of the diesel generator set when the diesel generator set is working. The mounting brackets 22 and the filter screen 23 on both sides are located on both sides of the diesel generator set, and the four engaging blocks 211 of the mounting bracket 22 are engaged and fixed with the engaging grooves 12 and the engaging base 13 of the heat sink 11. When the dust cover structure 2 is covered, the two internal lifting rods 24 are suspended in the air and are affected by their own gravity, and the lifting rods 24 move to the lowest position. At this time, the bottom end of the lifting rod 24 protrudes from the bottom surface of the mounting bracket 22, so that when the dust cover is installed, the protruding lifting rod 24 can be engaged with the switch slot 35 for auxiliary positioning. When the dust cover structure 2 is placed, the lifting rod 24 slides upward in the top plate 21, and the mounting brackets 22 on both sides of the top plate 21 slide relative to the lifting rod 24, so that the several transmission rods 25 connected in rotation between them rotate upward. At this time, the elastic contact head 26 at one end of the lifting rod 24 contacts and compresses the surface of the diesel generator set, and then contacts and fixes it closely with the surface, thereby completing the fixed installation of the dust cover structure 2 on the surface of the diesel generator set. The filter 23 on the surface of the dust cover structure 2 can prevent external dust from contacting the diesel generator set. After long-term work, a large amount of dust will adhere to the surface of the dust cover. When it is removed, the surface dust will fall off and may contact the surface of the diesel generator. At this time, by pulling the transmission handles 27 on both sides of the top plate 21, the transmission handles 27 on both sides slide upward relatively in the top plate 21. At this time, the transmission handle 27 indirectly drives the transmission gear 29 to rotate through the transmission rack 210, and indirectly drives the transmission rod 25 to extend downward when the dust cover structure 2 is lifted. At this time, the transmission rod 25 slides relatively with the mounting bracket 22, allowing the internal transmission rods 25 to rotate downward. At this time, the transmission rods 25 on both sides are in an inverted eight-shaped shape, which can make the dust cover structure 2 fall off from the surface of the diesel generator. When the dust cover structure 2 falls off from the surface of the diesel generator, the elastic contact head and the surface continuously rub against each other to generate vibration, so that the dust attached to the surface of the dust cover will actively fall down due to the vibration. At this time, when the bottom ends of the two transmission rods 25 are separated from the switch slot 35, the mechanical switch controls the electrostatic generation bar 32 on the top surface of the bottom plate 31 to work. The electrostatic generation bar 32 itself is attached with static electricity, and the fallen dust falls near the electrostatic generation bar 32 below. The electrostatic effect of the electrostatic generation bar 32 itself generates negative ions that can absorb nearby tiny particles. Thus, the dust is attracted to move to the collection outer slot 33 and the collection inner slot 34 on both sides of the electrostatic generation bar 32 for collection.

[0038] Working principle of the present invention: A heat dissipation and dust-proof mechanism for a diesel generator set of the present invention is provided with a dust cover structure 2. When the dust cover structure 2 is covered under the top surface of the diesel generator set, the lifting rod 24 and the top plate 21 slide relative to each other, thereby driving a plurality of transmission rods 25 to rotate, and the elastic contact head at one end of the transmission rod 25 contacts and compresses the surface of the diesel generator set, so that the diesel generator set can be closely contacted to complete the fixation; when dismantling, the dust cover structure 2 is lifted up by pulling the transmission handle 27, and the transmission handle 27 can drive the lifting rod 24 structure to descend and drive the transmission rod 25 to rotate downward, and rotate to the inverted eight direction with the smallest friction; as the dust cover and the diesel generator set move relative to each other, the elastic contact head and the surface of the diesel generator set continuously rub against each other to cause itself to vibrate; when the vibration is transmitted to the filter 23, the dust on the surface of the filter 23 falls off. By setting up a collecting structure 3, a switch slot 35 and an electrostatic generating strip 32 are provided on the top surface of the bottom plate 31 of the collecting structure 3. When the dust cover structure 2 is pre-installed, the switch slot 35 can be engaged with the bottom end of the lifting rod 24 for auxiliary positioning; when the dust cover structure 2 is disassembled, the bottom of the lifting rod 24 is separated from the mechanical switch of the switch slot 35, so that the electrostatic generating strip 32 can work to generate negative ions; as the dust falls from the surface of the upper filter 23, small particles of dust are attracted by the charge of the negative ions and can move to the collection inner slot 34 and the collection outer slot 33 for collection.

[0039] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
