Description

Technical Field

[0001] This invention relates to the field of diesel engine set technology, specifically to a diesel engine set that reduces noise and has a heat dissipation function. Background Technology

[0002] A diesel engine is an engine that burns diesel fuel to generate energy. When used in conjunction with a generator, it can form a generator set to generate electricity. In the current technology, the heat dissipation effect of diesel engine sets is not ideal, and the noise generated during operation is relatively large.

[0003] For example, patent publication number CN209654103U describes a diesel engine set for smoke removal and purification. The filter screen filters particulate matter in the flue gas, and the flue gas dissolves diesel fuel into vegetable oil after passing through oil-absorbing cotton. Nitrogen oxides and sulfur dioxide react with sodium hydroxide to produce sodium salt and water, and activated carbon plates adsorb and remove formaldehyde and odor, thus achieving the effect of smoke removal and purification. However, this diesel engine set has the problem of insufficient heat dissipation and relatively high noise during operation.

[0004] For example, patent publication number CN216280350U describes a diesel engine set with a shock-absorbing base. In this utility model, the bottom of the engine set is connected to the shock-absorbing box and the shock-absorbing mechanism through a connecting base. The shock-absorbing box and the shock-absorbing mechanism achieve dual linkage damping, thereby giving the engine set a better shock absorption effect. This can effectively prevent the phenomenon of internal parts falling off due to the long service life of the engine set, thus extending the service life of the engine set. However, this type of diesel engine set has the problem of insufficient heat dissipation and relatively high noise during operation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a diesel engine set that reduces noise and has a heat dissipation function, solving the problems of insufficient heat dissipation and excessive noise generated during operation of diesel engine sets.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a diesel engine set that reduces noise and has a heat dissipation function, comprising a unit body, a soundproof cover on the outside of the unit body, a cooling fan on one side of the unit body, a rapid heat dissipation mechanism connected to the cooling fan, the rapid heat dissipation mechanism being installed on the unit body, a buffer protection mechanism at the bottom of the soundproof cover, maintenance mechanisms on both the front and rear sides of the soundproof cover, and heat dissipation windows at both ends of the soundproof cover; The rapid heat dissipation mechanism includes two sets of heat dissipation fins and a fixed base. A bidirectional screw is rotatably connected inside the fixed base. One end of the bidirectional screw is connected to a first motor via a first gear pair. Two movable seats are threaded onto the bidirectional screw. A connecting seat is located at the bottom of each movable seat. A scissor bracket is installed between the connecting seat and the two movable seats. Support frames are fixedly connected to both ends of the connecting seat. Two reciprocating screws are rotatably connected to each support frame. The two reciprocating screws are connected via a sprocket and chain drive. A second motor is connected to one of the reciprocating screws via a second gear pair. A guide rack is fixedly connected to the bottom end of the support frame. A lifting seat is threaded onto the reciprocating screw. Multiple U-shaped cleaning racks are slidably connected inside the lifting seat. Brush bristles are fixedly connected to the inner wall surface of the U-shaped cleaning rack. A driven rack is fixedly connected to the end of the U-shaped cleaning rack. A return spring is fixedly connected to the end of the driven rack. A sector gear is provided at the bottom of the driven rack. A connecting shaft is fixedly connected between the multiple sector gears. A drive gear is fixedly connected to the end of the connecting shaft. A connecting rod is fixedly connected to the outer side of each of the two lifting seats. A blower seat is fixedly connected to the end of the connecting rod. Multiple air outlets are opened on the surface of the blower seat near the heat dissipation fins. A connecting air duct is connected to the end of the blower seat.

[0007] Preferably, the two sets of heat dissipation fins are fixedly disposed on the front and rear surfaces of the unit body, and the fixing base is fixedly installed on the top of the inner side of the sound insulation cover, so that the heat dissipation fins can increase the heat dissipation area of ​​the unit body, thereby effectively improving the heat dissipation effect.

[0008] Preferably, the bidirectional screw has two sections of threads in opposite directions, and the two movable seats are symmetrically arranged on the bidirectional screw. The movable seats are slidably connected to the inner wall of the fixed seat, so that when the bidirectional screw rotates, it can drive the two movable seats to move towards or away from each other.

[0009] Preferably, the drive gear meshes with the guide rack, and the sector gear matches the driven rack, so that the drive gear can roll along the guide rack, and the sector gear can periodically drive the driven rack to move.

[0010] Preferably, one end of the connecting duct is connected to the blower base, and the other end of the connecting duct is connected to the cooling fan, so that the cooling fan can blow air into the blower base, which can effectively dissipate heat from the heat dissipation fins.

[0011] Preferably, the buffer protection mechanism includes multiple fixed plates, each with a base frame at its bottom. The multiple fixed plates are fixedly installed at the four corners of the bottom of the soundproof cover. Multiple dampers are provided between the base frame and the fixed plates. A positioning block is fixedly connected to the bottom end of each fixed plate. The bottom end of the positioning block passes through the base frame and is fixedly connected to a buffer spring between it and the inner bottom surface of the base frame, which can play a good role in buffering and shock absorption protection.

[0012] Preferably, the maintenance mechanism includes a maintenance door, with rotating shafts fixedly connected to both ends of the top of the maintenance door. The top of the maintenance door is rotatably connected to the soundproof cover via the rotating shafts. An opening and closing screw is provided on one side of the maintenance door, and the opening and closing screw is rotatably connected to the inner wall of the soundproof cover. A guide slider is threaded onto the opening and closing screw. An opening and closing handle is connected to the bottom of the opening and closing screw via a third gear pair. A connecting arm is provided between the guide slider and the maintenance door. One end of the connecting arm is rotatably connected to the maintenance door, and the other end of the connecting arm is rotatably connected to the guide slider. The guide slider is slidably connected to the inner wall of the soundproof cover, which facilitates the opening of the soundproof cover to inspect the internal unit body.

[0013] This invention provides a diesel engine set that reduces noise and has a heat dissipation function. Compared with the prior art, it has the following advantages: (1) The diesel engine set that reduces noise and has heat dissipation function uses a soundproof cover to reduce noise, uses a cooling fan to dissipate heat on the entire engine body, and can increase the heat dissipation area of ​​the engine body by using a rapid heat dissipation mechanism, while cleaning the dust on the surface to improve the heat dissipation effect.

[0014] (2) The diesel engine set that reduces noise and has heat dissipation function compresses the buffer spring by moving along with the fixed plate through the positioning block. The damper plays a damping role during the continuous extension and contraction of the buffer spring, so that the damper and the buffer spring can work together to buffer and protect the engine body.

[0015] (3) The diesel engine set with noise reduction and heat dissipation function can be opened by rotating the opening and closing handle, which drives the opening and closing screw to rotate, which drives the guide slider to move, which drives the connecting arm to move, and the connecting arm to rotate the maintenance door. This makes it convenient to open the soundproof cover to inspect the internal engine body, effectively improving the convenience of maintenance. Attached Figure Description

[0018] The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-4 This invention provides a technical solution: a diesel engine set with noise reduction and heat dissipation function, including a unit body 3, a soundproof cover 1 on the outside of the unit body 3, a cooling fan 4 on one side of the unit body 3, a rapid heat dissipation mechanism 2 connected to the cooling fan 4, the rapid heat dissipation mechanism 2 being installed on the unit body 3, a buffer protection mechanism 5 at the bottom of the soundproof cover 1, maintenance mechanisms 6 on both the front and rear sides of the soundproof cover 1, and heat dissipation windows 7 at both ends of the soundproof cover 1. The soundproof cover 1 can play a role in sound insulation and noise reduction, the cooling fan 4 can dissipate heat from the unit body 3 as a whole, and the rapid heat dissipation mechanism 2 can increase the heat dissipation area of ​​the unit body 3, while cleaning the surface dust and improving the heat dissipation effect.

[0020] The rapid heat dissipation mechanism 2 includes two sets of heat dissipation fins 201 and a fixed base 202. The two sets of heat dissipation fins 201 are fixedly installed on the front and rear sides of the unit body 3. The fixed base 202 is fixedly installed on the top of the inner side of the soundproof cover 1, so that the heat dissipation fins 201 can increase the heat dissipation area of ​​the unit body 3, thereby effectively improving the heat dissipation effect. A bidirectional screw 203 is rotatably connected inside the fixed base 202. One end of the bidirectional screw 203 is connected to a first motor 204 through a first gear pair. Two movable seats 205 are threadedly connected to the bidirectional screw 203. The bidirectional screw 203 has two sections of threads in opposite directions. The two movable seats 205 are symmetrically arranged on the bidirectional screw 203, and the movable seats 205 are slidably connected to the inner wall of the fixed base 202, so that the bidirectional screw... When rod 203 rotates, it can drive two movable seats 205 to move towards or away from each other. A connecting seat 207 is provided at the bottom of the two movable seats 205. A scissor lift 206 is installed between the connecting seat 207 and the two movable seats 205. The first motor 204 can drive the movable seats 205 to move towards or away from each other via the bidirectional screw 203, thereby enabling the scissor lift 206 to extend and retract, which in turn drives the connecting seat 207 to rise and fall. This facilitates the separation and approach of the unit body 3, making it convenient for maintenance and disassembly of the unit body 3. Support frames 208 are fixedly connected to both ends of the connecting seat 207. Two reciprocating screws 209 are rotatably connected to each support frame 208, and the two reciprocating screws 209 are connected by a sprocket and chain. The transmission connection enables the two reciprocating lead screws 209 to rotate synchronously. A second motor 210 is connected to one of the reciprocating lead screws 209 via a second gear pair. A guide rack 211 is fixedly connected to the bottom end of the support frame 208. A lifting seat 212 is threadedly connected to the two reciprocating lead screws 209, allowing the second motor 210 to drive the reciprocating lead screws 209 to rotate, thereby driving the lifting seat 212 to move up and down reciprocally. Multiple U-shaped cleaning frames 213 are slidably connected inside the lifting seat 212. Brush bristles 214 are fixedly connected to the inner surface of the U-shaped cleaning frames 213. A driven rack 215 is fixedly connected to the end of the U-shaped cleaning frame 213, and a return spring 216 is fixedly connected to the end of the driven rack 215 to return the driven rack 215 to its original position. In this configuration, a sector gear 217 is provided at the bottom of the driven rack 215. The drive gear 219 meshes with the guide rack 211. The sector gear 217 matches the driven rack 215, allowing the drive gear 219 to roll along the guide rack 211. The sector gear 217 can periodically drive the driven rack 215 to move. A connecting shaft 218 is fixedly connected between multiple sector gears 217. The end of the connecting shaft 218 is fixedly connected to the drive gear 219. Connecting rods 220 are fixedly connected to the outer sides of both lifting seats 212. A blower seat 221 is fixedly connected to the end of the connecting rod 220. Multiple air outlets 222 are provided on the surface of the blower seat 221 near the heat dissipation fins 201. A connecting duct 223 is connected to the end of the blower seat 221.One end of the connecting duct 223 is connected to the air blower base 221, and the other end of the connecting duct 223 is connected to the cooling fan 4, allowing the cooling fan 4 to blow air into the air blower base 221, thus effectively dissipating heat from the heat dissipation fins 201.

[0021] Please see Figure 1 and Figure 5 The buffer protection mechanism 5 includes multiple fixed plates 501. The bottom of the fixed plates 501 is provided with a base frame 502. The multiple fixed plates 501 are fixedly installed at the four corners of the bottom of the soundproof cover 1. Multiple dampers 503 are provided between the base frame 502 and the fixed plates 501. A positioning block 504 is fixedly connected to the bottom end of the fixed plate 501. The bottom end of the positioning block 504 passes through the base frame 502 and is fixedly connected to the inner bottom surface of the base frame 502 with a buffer spring 505. The buffer spring 505 can be compressed by the positioning block 504 moving with the fixed plate 501. The damper 503 plays a damping role in the continuous expansion and contraction of the buffer spring 505, so that the damper 503 and the buffer spring 505 can work together to provide buffer and shock absorption protection for the unit body 3.

[0022] Please see Figure 1 and Figure 6 The maintenance mechanism 6 includes an inspection door 601. Rotating shafts 602 are fixedly connected to both ends of the top of the inspection door 601. The top of the inspection door 601 is rotatably connected to the soundproof cover 1 via the rotating shafts 602. An opening / closing screw 603 is provided on one side of the inspection door 601, rotatably connected to the inner wall of the soundproof cover 1. A guide slider 605 is threaded onto the opening / closing screw 603. An opening / closing handle 604 is connected to the bottom of the opening / closing screw 603 via a third gear pair. A connecting arm 606 is provided between the guide slider 605 and the inspection door 601. One end of the connecting arm 606... The connecting arm 606 is rotatably connected to the inspection door 601, and the other end of the connecting arm 606 is rotatably connected to the guide slider 605. The guide slider 605 is slidably connected to the inner wall of the soundproof cover 1. By rotating the opening and closing handle 604, the opening and closing handle 604 rotates the opening and closing screw 603, which in turn moves the guide slider 605. The movement of the guide slider 605 moves the connecting arm 606, which in turn rotates the inspection door 601. This allows for convenient opening of the soundproof cover 1 to inspect the internal unit body 3, effectively improving the convenience of maintenance.

[0023] In use, the soundproof cover 1 serves to reduce noise. The cooling fan 4 provides overall cooling for the unit body 3. The first motor 204 drives the bidirectional screw 203 to rotate. The rotation of the bidirectional screw 203 causes the movable seat 205 to move towards each other. The movement of the movable seat 205, via the scissor lift 206, causes the connecting seat 207 to move downwards, placing the lifting seat 212 onto the cooling fins 201. Then, the second motor 210 simultaneously drives two reciprocating screws 209 to rotate. The rotation of the reciprocating screws 209 causes the lifting seat 212 to move up and down reciprocally. The lifting seat 212 drives the U-shaped cleaning frame 213 and the blower seat 221 to move. During this process, the unit... The driving gear 219 moves with the lifting seat 212 and rolls along the guide rack 211. The rotation of the driving gear 219 drives the connecting shaft 218 to rotate. The rotation of the connecting shaft 218 drives the sector gear 217 to rotate. The sector gear 217, in conjunction with the return spring 216, drives the driven rack 215 to move back and forth. The movement of the driven rack 215 drives the U-shaped cleaning frame 213 to move. The movement of the U-shaped cleaning frame 213 uses the brush bristles 214 to clean the surface of the heat dissipation fins 201. At the same time, the cooling fan 4 blows air into the blower seat 221 through the connecting air duct 223, which dissipates heat from the heat dissipation fins 201 and improves the heat dissipation effect.
