Description

Technical Field

[0001] The invention belongs to the technical field of diesel generator sets, and in particular relates to an intelligent sound-absorbing and heat-insulating diesel generator set. Background Art

[0002] A diesel generator is a small power generation device, which refers to a power machine that uses diesel as fuel and a diesel engine as the prime mover to drive the generator to generate electricity. The whole unit is generally composed of a diesel engine, a generator, a control box, a fuel tank, a storage battery for starting and control, a protection device, an emergency cabinet and other components. A diesel generator is a combination of a diesel engine and a generator to generate electricity. Diesel compression ignition engines are usually designed to run on fuel oil, but some types are suitable for other liquid fuels or natural gas.

[0003] The basic structure of a diesel generator set is composed of a diesel engine and a generator. The diesel engine is used as a power to drive the generator to generate electricity. During the operation of the diesel generator set, mechanical noise and exhaust noise will be generated, and the exhaust noise generated by the diesel engine is particularly serious, mainly generated by the exhaust system. It includes the diesel high-pressure combustion noise in the combustion chamber, the low-frequency pulsating noise caused by periodic exhaust smoke, the air column resonance noise in the exhaust pipe, and the cylinder Helmholtz resonance noise. Exhaust noise is the part with larger energy and higher sound level in the diesel engine noise, which not only causes noise pollution but also affects the normal working environment. The existing noise prevention mechanism design is relatively simple, generally only setting the exhaust pipe as a noise reduction material, the noise prevention effect is not good, and it is not conducive to the safe use of the device. At the same time, the working environment requirements of the diesel engine are high, and the temperature balance needs to be maintained, so it is necessary to set the insulation through the corresponding insulation mechanism to prevent the heat from being lost too quickly. However, the existing insulation mechanisms are generally only locked and fixed by bolts, which is inconvenient to install and disassemble, and is not conducive to improving the work efficiency of personnel.

[0013] Furthermore, it also includes a cover body fixed on the outer wall of the water tank, and a rotating circle is connected to the center of the outer wall of the cover body through a movable shaft. One end of the movable shaft passes through the cover body and extends to the central gear on the inner wall of the cover body. The upper and lower ends of the central gear are respectively engaged with a first gear plate and a second gear plate that move synchronously in the opposite directions, and the extension sections of the first gear plate and the second gear plate are both connected to the T-shaped beam.

[0014] Furthermore, the transmission ratio between the central gear and the first gear plate is kept the same as the transmission ratio between the central gear and the second gear plate, and movable holes connected to the T-shaped crossbeam are provided at both ends of the outer wall of the housing.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] (1) A support mechanism is provided. The support plate on the support mechanism can not only support and connect the generator and the diesel engine, but also play a corresponding buffering and adjusting role. The setting of the telescopic rod can facilitate the position deviation of the support plate during the movement, thereby improving the safety of the device.

[0023] (2) A heat insulation installation mechanism is provided. The heat insulation box can insulate the diesel engine and effectively prevent heat loss, thereby ensuring the balance of the internal working temperature. When the diesel engine needs to be repaired, the handle on the heat insulation board needs to be lifted upwards to pull out the heat insulation board. In this way, the maintenance port on the side panel can be opened and connected to the diesel engine, thereby facilitating the maintenance of the diesel engine. When the interior of the heat insulation box needs to be installed and disassembled as a whole, the U-shaped rod and the positioning hole need to be further separated. This can facilitate the separation of the plug on the side panel from the slot on the heat insulation box. The diesel engine is then moved out on the roller by rolling friction, thereby facilitating the disassembly of the internal components of the heat insulation box as a whole. Moreover, compared with the locking and fixing method of the bolt assembly in the prior art, the installation and maintenance are convenient, which is conducive to personnel operation, greatly improves work efficiency, and effectively improves the heat insulation performance of the device.

[0024] (3) A noise silencing mechanism is provided. By providing a water tank and a silencing pipe with silencing cotton on the first exhaust pipe, the noise can be effectively reduced by absorbing sound waves through the silencing material and the water body. At the same time, a rotating circle is provided on the cover body. The rotation of the rotating circle drives the first gear plate and the second gear plate to move in the opposite direction. With the help of mechanical transmission, the telescopic box on the water tank moves in the opposite direction. In this way, the depth of the water body in the water tank is changed by changing the volume of the water tank. Water bodies of different depths can absorb noises of different vibration amplitudes. In addition, the volume of the silencing cavity in the silencing assembly can be changed during the movement of the gear plate. When the noise passes through the silencing hole and enters the silencing cavity, the vibration amplitude of the sound wave is reduced. The change in the volume of the silencing cavity can reduce the noise of different vibration amplitudes. At the same time, the vibration amplitude of the noise will change when it passes through the large pipe and the small pipe. The noise waves are offset and interfered with each other through the air collecting pipe where the two converge, thereby further achieving the purpose of noise reduction. The exhaust noise generated by the exhaust pipe of the diesel engine is effectively silenced, reducing noise pollution and providing personnel with a quiet and good working environment.

[0039] Support mechanism 2, support mechanism 2 includes support plate 3, both sides of the bottom end of support plate 3 are connected to bottom plate 1 through telescopic rods 4, and compression spring 5 at the bottom of support plate 3 is arranged between telescopic rods 4, one end of compression spring 5 extends to bottom plate 1, and support mechanism 2 is used to support and fix diesel engine 6 and generator 7 on support plate 3;

[0040] The heat-insulating installation mechanism 8 includes a heat-insulating box 9 with a slot and accommodating and connected to the diesel engine 6, and a slot is provided on the open outer wall of the heat-insulating box 9 and a side panel 10 is installed by plugging, and a maintenance port 11 connected to the diesel engine 6 is provided at the center of the side panel 10, and both ends of the side panel 10 are integrally formed with a protrusion 12, and a heat-insulating plate 13 is movably limited and installed between the protrusions 12; wherein, a positioning hole is provided at the connection between the protrusion 12 and the heat-insulating box 9 and is limited and fixed by a U-shaped rod 14, and both ends of the side panel 10 are provided with an insert block 15 connected to the slot, and a roller 16 is provided in the length direction of the bottom end of the inner wall of the heat-insulating box 9, one end of the roller 16 extends to the rotating shaft, and the other end is in contact with the diesel engine 6.

[0041] A support mechanism 2 is provided, and the support plate 3 on the support mechanism 2 can not only support and connect the generator 7 and the diesel engine 6, but also play a corresponding buffering and regulating role. The provision of the telescopic rod 4 can facilitate the position deviation of the support plate 3 during the movement, thereby improving the safety of the device.

[0042] Specifically, the support mechanism 2 can be additionally provided with a rectangular groove, so as to provide corresponding support limit space for the diesel engine 6 and the generator 7, so as to prevent the diesel engine 6 and the generator 7 from being separated from the support plate 3 in the case of mechanical vibration. By extension, in order to increase the buffering effect of the support mechanism 2, a corresponding magnet can be provided in the telescopic rod 4, and the opposite sides of the magnet are arranged with the same poles. By utilizing the principle of "like repels like", a reverse force can be provided during the downward movement of the telescopic rod 4, thereby avoiding the situation where the force is too large and the structure is damaged by collision. The drawings in this specification are not drawn, but the above text has been clearly and specifically disclosed, and therefore does not affect the implementation of the technical solution of this patent.

[0043] refer to Figure 1 , Figure 2 and Figure 4A handle 39 is fixedly installed on the top of the insulation board 13, and the thickness of the insulation board 13 is kept the same as the length of the extended part of the protrusion 12. As the handle 39 drives the insulation board 13 to move up and down, the side panel 10 and the insulation box 9 are closed or opened with each other, and an active cavity connected to the roller 16 is provided on the inner wall of the insulation box 9. The roller 16 is distributed along the length direction of the active cavity. As the roller 16 rotates back and forth, the diesel engine 6 and the insulation box 9 are in contact with each other or separated.

[0044] Specifically, the output shaft of the diesel engine 6 and the input shaft of the generator 7 are fixedly connected by a coupling. The setting of the above coupling can ensure the stability of the rotational speed between the two. In addition, they can also be connected through a pulley. The generator 7 and the diesel engine 6 are connected by a belt, and the pulleys at both ends control the rotational speed and direction through telescopic belts. The above specific transmission components are obvious to technicians in this field and will not be described in detail here.

[0045] The telescopic rod 4 and the compression spring 5 are symmetrically arranged relative to the center of the support plate 3, and a mounting seat connected to the support plate 3 is provided at the bottom of the generator 7. The maintenance port 11 on the side panel 10 is provided to facilitate the withdrawal of the insulation board 13 from the insulation box 9, so that the outside of the diesel engine 6 can be directly repaired through the maintenance port 11. In addition, the plug 15 on the side panel 10 can be conveniently separated from the slot by directly pulling out the U-shaped rod 14 from the positioning holes on the side panel 10 and the insulation box 9. The U-shaped rod 14 is relative to the stop pins of the side panel 10 and the insulation box 9, and the two are locked or separated with each other by direct fastening and pulling out, thereby facilitating operation. Moreover, the roller 16 connected to the rotating shaft on the inner wall of the insulation box 9 can separate the diesel engine 6 from the insulation box 9 by rolling friction, thereby facilitating opening the entire box body. Moreover, the rolling friction method is conducive to reducing the friction damage of the transmission parts and improving the service life of the device.

[0046] A heat insulation installation mechanism 8 is provided, and the setting of the heat insulation box 9 can play a role in heat insulation and heat preservation for the diesel engine 6, effectively preventing heat loss, thereby ensuring the balance of the internal working temperature. When it is necessary to repair the outside of the diesel engine 6, it is only necessary to lift the handle 39 on the heat insulation board 13 upwards to pull out the heat insulation board 13, so that the maintenance port 11 on the side panel 10 can be opened and connected to the diesel engine 6, thereby facilitating the maintenance work of the diesel engine 6. When it is necessary to install and disassemble the interior of the heat insulation box 9 as a whole, it is necessary to further separate the U-shaped rod 14 from the positioning hole, so that it is convenient to separate the plug block 15 on the side panel 10 from the slot on the heat insulation box 9, and then the diesel engine 6 is moved out on the roller 16 by rolling friction, thereby facilitating the disassembly of the internal components of the heat insulation box 9 as a whole. Moreover, compared with the locking and fixing method of the bolt assembly in the prior art, it is convenient to install and maintain, which is conducive to personnel operation, greatly improves work efficiency, and effectively improves the heat insulation performance of the device.

[0047] refer to Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 , the noise silencing mechanism 17, the noise silencing mechanism 17 includes a first exhaust pipe 18 placed on the diesel engine 6, one end of the first exhaust pipe 18 is connected to a water tank 20 through an air pump 19, a water pipe and a second exhaust pipe 21 adapted thereto are respectively installed on the top of the water tank 20, a large pipe 23 and a small pipe 24 are respectively connected to the second exhaust pipe 21 through a U-shaped pipe 22, and one end of the large pipe 23 and the small pipe 24 are both extended to the air collecting pipe 25;

[0048] Among them, the bottom end of the water tank 20 is fixed to the panel through the first bracket 26, and the bottom ends of the large pipe 23 and the small pipe 24 are fixed to the panel through the second bracket 27, and the inner walls of the large pipe 23 and the small pipe 24 are adhesively connected with sound-absorbing cotton, the panel and the column are fixedly connected by reinforcing ribs, and a lifting ring is fixedly installed on the air pump 19, which is limitedly connected to the lifting hook on the third bracket 28, and one end of the third bracket 28 extends to the top plate.

[0049] Specifically, the intelligent sound-absorbing and heat-insulating diesel generator set also includes a cover body fixed on the outer wall of the water tank 20, and a rotating circle 29 is connected to the center of the outer wall of the cover body through a movable shaft. One end of the movable shaft passes through the cover body and extends to the central gear 30 on the inner wall of the cover body. The upper and lower ends of the central gear 30 are respectively engaged with a first gear plate 31 and a second gear plate 32 that move synchronously in the opposite directions. The extended sections of the first gear plate 31 and the second gear plate 32 are connected to the T-shaped beam 33.

[0050] The transmission ratio between the central gear 30 and the first gear plate 31 is the same as the transmission ratio between the central gear 30 and the second gear plate 32 , and movable holes connected to the T-shaped crossbeam 33 are provided at both ends of the outer wall of the housing.

[0051] The noise silencing mechanism 17 achieves the purpose of noise reduction through three methods: sound wave absorption by water, superposition and cancellation of sound waves, and absorption of sound waves of different amplitudes by the silencing chamber. In addition, by rotating the circle 29, with the help of the meshing transmission of gears, the first gear plate 31 and the second gear plate 32 drive the depth of the water body in the water tank 20 to adjust the height. When the gear plate drives the water body depth to be compressed and increased, the noise on the first exhaust pipe 18 passes through the deep water body, thereby absorbing high-decibel noise sound waves through the water body. At this time, the gear plate drives the second box body 37 to move toward the inner wall of the first box body 36, so that the volume of the silencing chamber becomes smaller, so that the high-decibel noise can be effectively absorbed in cooperation with the silencing hole 38, thereby achieving the purpose of noise reduction.

[0052] In addition, the vibration amplitude of the noise sound waves in the large pipe 23 and the small pipe 24 will change with the size of the pipe. At the same time, the phase difference of the sound waves in the large pipe 23 and the small pipe 24 is a half-integer multiple. The peaks and troughs of the sound waves are superimposed, which will lead to cancellation. The sound gradually decreases until it disappears.

[0053] Specifically, one end of the T-shaped beam 33 is connected to the telescopic box 34 on the water tank 20, and the other end passes through the large pipe 23 and the small pipe 24 respectively and extends to the silencer assembly 35. The telescopic box 34 is movably connected to the outer wall of the water tank 20, and the silencer assembly 35 is respectively placed inside the large pipe 23 and the small pipe 24.

[0054] The silencer assembly 35 includes a first box body 36 and a second box body 37. One end of the first box body 36 is fixedly connected to the inner wall of the large pipe 23 by a mounting rod. The second box body 37 is telescopically connected to the outer wall of the first box body 36. Silencing holes 38 are provided on the first box body 36 and the second box body 37. The silencer holes 38 and the inner walls of the first box body 36 and the second box body 37 together form a silencer cavity. As the rotating circle 29 rotates, the telescopic box 34 drives the water depth in the water tank 20 to increase or decrease, and at the same time, the second box body 37 drives the volume of the silencer cavity on the first box body 36 to decrease or increase synchronously.

[0055] A noise silencing mechanism 17 is provided. By providing a water tank 20 and a silencing pipe with silencing cotton on the first exhaust pipe 18, the noise can be effectively reduced by absorbing sound waves through the silencing material and the water body. At the same time, a rotating circle 29 is provided on the cover body. The rotation of the rotating circle 29 drives the first gear plate 31 and the second gear plate 32 to move in the opposite direction. With the help of mechanical transmission, the telescopic box 34 on the water tank 20 moves in the opposite direction. In this way, the depth of the water body in the water tank 20 is changed by changing the volume of the water tank 20, and water bodies of different depths can absorb noises of different vibration amplitudes. In addition, During the movement of the gear plate, the volume of the silencer chamber in the silencer assembly 35 can be changed. When the noise passes through the silencer hole 38 and enters the silencer chamber, the vibration amplitude of the sound wave is reduced. The change in the volume of the silencer chamber can reduce the noise with different vibration amplitudes. At the same time, the vibration amplitude of the noise will change when it passes through the large pipe 23 and the small pipe 24. The air collecting pipe 25 where the two converge will cause the sound waves of the noise to cancel each other out, thereby further achieving the purpose of noise reduction. The exhaust noise generated by the exhaust pipe of the diesel engine 6 is effectively silenced, reducing noise pollution and providing personnel with a quiet and good working environment.

[0056] The technical solution of this patent adjusts the volume of the water tank 20 and changes the volume of the silencer chamber in the pipeline by rotating the circle 29, so that it can automatically adapt to the vibration amplitude of different noises to achieve the purpose of noise reduction and silencing, and has a high degree of intelligence.
