Description

Technical Field

[0001] The present invention relates to a silent box structure and an operating method thereof, in particular to a silent box structure of a hybrid diesel generator set and an operating method thereof, belonging to the technical field of mechanical equipment. Background Art

[0002] The diesel engine uses compression ignition, that is, the air is compressed to a high temperature and high pressure state in the cylinder, causing the injected diesel to self-ignite. This combustion method is different from the spark plug ignition method of the gasoline engine. The diesel will produce a large pressure shock at the moment of self-ignition, causing the pressure in the cylinder to rise sharply, thereby causing strong vibration and noise. In addition, the combustion speed of diesel is relatively slow, the combustion process lasts for a long time in the cylinder, and there are relatively more incomplete combustion cases. Incomplete combustion will produce some unburned hydrocarbons and particulate matter, which will continue to burn or explode in the subsequent combustion process, further increasing the noise.

[0003] When the noise is too loud, on the one hand it affects the driver's driving comfort. On the other hand, due to the loud noise, it is difficult for the driver to hear the horns of other vehicles in time, and the reaction time is prolonged, which in turn affects driving safety. If the diesel engine is simply soundproofed by a soundproof cover, the heat generated by the engine cannot be dissipated in time, causing the temperature in the cylinder to be too high, and the air expands due to the heat, resulting in a decrease in the actual amount of air entering the cylinder, a decrease in power output, and a significant weakening of the car's power. The fuel cannot be fully burned, increasing fuel consumption. Therefore, it is necessary to achieve the purpose of heat dissipation while soundproofing.

[0004] Therefore, there is an urgent need to improve the silent box of the hybrid diesel generator set to solve the above-mentioned problems. Summary of the Invention

[0013] Preferably, an electrically connected processor and temperature sensor are fixedly provided on the side surface inside the soundproof box, the exhaust motor, the sealing ring drive motor and the air flow plate rotating motor are all communicated with the processor, and an air flow sensor is fixedly provided inside the inclined flow channel, and the air flow sensor is communicated with the processor.

[0014] Preferably, symmetrically distributed partition mounting blocks are provided on the inner side of the soundproof box, battery partitions are fixedly provided on the partition mounting blocks, and the battery partitions are provided with partition mounting grooves that are snap-connected to the partition mounting blocks, and both sides of the battery partitions are sprayed with flame retardant paint; An assembly plate is fixedly provided on the outer side of the soundproof box below the sealing plate.

[0015] A method for operating a silent box structure of a hybrid diesel generator set, comprising the following steps: Step 1: Installation: Install the partition mounting groove on the battery partition to the partition mounting block, form the engine compartment and battery compartment inside the silent box, and directly cover the diesel engine and battery with the silent box. After adjusting the position, fix the silent box with the assembly plate; Step 2: Debugging and repairing: Remove the movable sealing plates on both sides of the silent box to inspect and debug the diesel engine or battery. The disassembly and installation of the movable sealing plates are as follows: To install, first insert the upper end of the movable sealing plate into the interior of the upper clamping head, and make it fit into the interior of the clamping slot through the clamping head. Then lift the movable sealing plate upwards through the installation handle on the movable sealing plate, so that the bottom of the movable sealing plate fits into the interior of the lower clamping head. The installation of the movable sealing plate is completed under the action of the spring. To disassemble, lift the movable sealing plate upwards by the mounting handle, first separate the bottom of the movable sealing plate from the lower clamp, and then remove the upper end of the movable sealing plate from the inside of the upper clamp; Step 3: Heat dissipation operation. During operation, the arc-shaped airflow plate is rotated by starting the airflow plate rotation motor on the arc-shaped airflow plate, and at the same time, the sealing ring drive motor is started to make the air inlet of the sealing ring correspond to the air suction hole. After the silent box is running, the air flows through the arc-shaped airflow plate and the flow rate is greater than the flow rate at the bottom of the silent box. Therefore, the air enters the interior of the silent box through the air suction hole on the front air flow mechanism and flows out through the oblique flow channel, thereby achieving the purpose of heat dissipation inside the silent box. When idling, the temperature sensor detects that the temperature inside the silent box is too high and pushes the information to the processor. The processor pushes the information to the exhaust motor, which exchanges the heat inside the silent box through the exhaust motor to achieve the purpose of heat dissipation; Step 4: Sealing operation, turn off the air flow plate rotation motor to make the arc air flow plate rotate downward and cover the port of the oblique flow channel, and at the same time start the sealing ring drive motor to make the sealing ring air inlet away from the air suction hole and seal the air suction hole to reduce air flow inflow.

[0016] The present invention has at least the following beneficial effects: 1. When the diesel engine is in the idling state, the exhaust motor inside the front air flow mechanism is started to direct the airflow through the suction hole inside the U-shaped guide block into the interior of the silent box, so as to achieve the purpose of cooling the interior of the silent box through the airflow. After the airflow and noise enter the interior of the silent box, an inclined flow channel is opened inside the upper side of the silent box. The inclined flow channel is connected with the interior of the silent box through several box exhaust strip holes, carrying the heat and noise inside the silent box into the interior of the box exhaust strip holes through the inclined flow channel, and then flowing out from the inclined flow channel, thereby achieving the purpose of heat dissipation while reducing noise.

[0017] 2. When the diesel engine is idle, some mechanical components will rust when in contact with the air. Therefore, the diesel engine needs to be protected. First, the arc-shaped airflow plate is rotated by the airflow plate rotating motor and covered on the top of the inclined flow channel to prevent debris or rainwater from entering the interior of the silent box. Then, the sealing ring driving motor inside the driving motor slot is started, and the sealing ring is rotated by the sealing ring driving head so that the air inlet of the sealing ring is away from the side of the air suction hole to achieve the purpose of sealing the air suction hole. Therefore, the outside air cannot flow inside the silent box, thereby reducing the degree of rust of the diesel engine and improving the service life of the diesel engine.

[0018] 3. Insert the upper end of the movable sealing plate into the interior of the upper clamping head, and make it fit into the interior of the clamping slot through the clamping head. Then lift the movable sealing plate upwards through the installation handle on the movable sealing plate, so that the bottom of the movable sealing plate is clamped into the interior of the lower clamping head. The installation of the movable sealing plate is completed under the action of the spring. The disassembly is opposite to the above method, so it is convenient for disassembly and later maintenance of the diesel engine.

[0019] 4. A temperature sensor is fixedly installed inside the silent box, and an airflow sensor is installed inside the inclined flow channel. When the temperature sensor detects that the temperature is too high and the airflow sensor detects that the flow rate is too low, the information will be pushed to the processor, and the processor will immediately start the exhaust motor and the airflow plate rotation motor to increase the air flow rate and achieve rapid cooling. When the diesel engine is idle, the sealing ring drives the motor to seal the air intake hole, which has a high degree of automation and improves the heat dissipation efficiency.

[0022] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figures 1-12 As shown, the silent box structure of the hybrid diesel generator set provided by this embodiment includes a silent box 1. The diesel engine adopts compression ignition. This combustion method is different from the spark plug ignition method of the gasoline engine. The diesel will produce a large pressure shock at the moment of self-ignition, causing the pressure in the cylinder to rise sharply, thereby causing strong vibration and noise. The air is compressed to an extremely high pressure, usually up to 15-25 atmospheres. After the diesel is injected, it burns rapidly, and the pressure may instantly rise to 60-100 atmospheres or even higher. This drastic change in pressure will produce obvious knocking sounds. When the diesel is not completely burned, hydrocarbons and particulate matter will be produced. In the subsequent combustion process, the diesel will continue to burn or explode, further increasing the noise. When the noise is too loud, on the one hand, it affects the driver's driving comfort. On the other hand, due to the relatively loud noise, it is difficult for the driver to hear the horn of other vehicles in time, and the reaction time is prolonged, which in turn affects driving safety. Therefore, the silent box 1 is directly covered on the diesel engine to reduce the noise during the transmission process, thereby improving the driver's comfort and safety. While sealing and sound insulation, since the engine generates a large amount of heat during operation, if the heat is not dissipated in time, the temperature in the cylinder will be too high, and the air will expand due to the heat, resulting in a reduction in the actual amount of air entering the cylinder, a reduction in power output, and a significant weakening of the car's power. The fuel cannot be fully burned, which increases fuel consumption. The outer side of the silent box 1 is provided with a symmetrically distributed front air intake mechanism 2, which is connected to the interior of the silent box 1 through a grille mounting hole 101. The front air intake mechanism 2 is connected to the interior of the silent box 1 through the grille mounting hole 101, so the front air intake mechanism 2 can pass air into the interior of the silent box 1 through the grille mounting hole 101 to achieve the purpose of cooling. The interior of the front air intake mechanism 2 is fixedly connected to the exhaust motor 3 through a fan fixing rod 204, and the front air intake mechanism 2 is connected to symmetrically distributed U-shaped guide blocks 206. Suction holes 203 are opened on the front air intake mechanism 2 between the U-shaped guide blocks 206; When the diesel engine is in an idling state, the exhaust motor 3 inside the front air flow mechanism 2 is started to direct the air flow into the interior of the silent box 1 through the air suction hole 203 inside the U-shaped guide block 206, so as to achieve the purpose of cooling the interior of the silent box 1 through the air flow. After the air flow and noise enter the interior of the silent box 1, an oblique flow channel 106 is opened inside the upper side surface of the silent box 1. The oblique flow channel 106 is connected to the interior of the silent box 1 through a number of box exhaust strip holes 107, carrying the heat and noise inside the silent box 1 into the interior of the box exhaust strip holes 107 through the oblique flow channel 106, and then flowing out from the oblique flow channel 106. Therefore, the path of the air flow is: Air suction hole - inside of the front air flow mechanism - grille installation hole - inside of the silent box - box exhaust strip hole - oblique flow channel discharge; When the diesel engine is running, a sealing ring groove 201 is provided at the outer port of the front air flow mechanism 2, a driving motor groove 202 is provided on one side of the sealing ring groove 201, a sealing ring 4 is rotatably provided inside the sealing ring groove 201, a sealing ring driving motor 5 is fixedly provided inside the driving motor groove 202, a sealing ring driving head 501 for driving the sealing ring 4 to rotate is provided at the output end of the sealing ring driving motor 5, a rubber ring is fixedly provided on the outer side surfaces of the sealing ring 4 and the sealing ring driving motor 5, a sealing ring air inlet 401 is provided on the sealing ring 4, wherein after the sealing ring 4 rotates, the sealing ring air inlet 401 corresponds to the air suction hole 203, and the front air blower An air inlet sealing plate 205 is fixedly provided at the outer port of the mechanism 2. By starting the sealing ring driving motor 5 inside the driving motor slot 202, the sealing ring air inlet 401 on the sealing ring 4 is aligned with the air suction hole 203, so that the external air flows into the interior of the front air intake mechanism 2 through the air suction hole 203. During the movement of the diesel engine, the air flow plate rotating motor 701 rotates the arc-shaped air flow plate 7 to a certain angle, and the flow velocity on the upper side of the arc-shaped air flow plate 7 will increase, and a negative pressure state will be formed inside the silent box 1. Therefore, the air will enter the interior of the silent box 1 through the air suction hole 203 and be sucked out through the oblique flow channel 106. At the same time, the U-shaped guide block 206 is consistent with the direction of movement of the diesel engine, and the air flow will directly enter the interior of the silent box 1 through the air suction hole 203, so as to achieve the purpose of heat dissipation inside the silent box 1. An air flow plate protection block 108 is fixedly provided at the upper end of the oblique flow channel 106, and an arc-shaped air flow plate 7 is rotatably provided inside the air flow plate protection block 108. One end of the arc-shaped air flow plate 7 is fixedly provided on the air flow plate protection block 108 through the air flow plate rotating motor 701. The rotation angle of the arc-shaped air flow plate 7 can be adjusted by the air flow plate rotating motor 701. One end of the arc-shaped air flow plate 7 is extended to the outside of the air flow plate protection block 108 and is arranged directly above the oblique flow channel 106. The angle range of the arc-shaped air flow plate 7 rotated by the air flow plate rotating motor 701 is 0-75 degrees, so the flow velocity above the arc-shaped air flow plate 7 can be increased, thereby improving the efficiency of heat exchange. In addition, the ventilation holes 107 and the oblique flow channel 106 are arranged inside the silent box 1. While reducing the temperature inside the silent box 1, the noise generated is reflected inside the ventilation holes 107 and the oblique flow channel 106, thereby also achieving the purpose of reducing noise. When the diesel engine is idle, some mechanical components will rust when in contact with the air. Therefore, the diesel engine needs to be protected, specifically: First, the arc-shaped airflow plate 7 is rotated by the airflow plate rotating motor 701, and covers the top of the inclined flow channel 106 to prevent debris or rainwater from entering the interior of the silent box 1, and then the sealing ring driving motor 5 inside the driving motor slot 202 is started, and the sealing ring 4 is rotated by the sealing ring driving head 501 to make the sealing ring air inlet 401 away from one side of the air suction hole 203, so as to achieve the purpose of sealing the air suction hole 203. Therefore, the external air cannot flow inside the silent box 1, thereby reducing the degree of rust of the diesel engine and improving the service life of the diesel engine.

[0024] Further, such as Figure 1 、 Figure 5 、 Figure 6 as well as Figure 7 As shown, a sound-absorbing panel bin 102 connected to the grille mounting hole 101 is provided inside the grille mounting hole 101, a sound-absorbing panel 10 is fixedly provided inside the sound-absorbing panel bin 102, a metal grille 8 is fixedly provided inside the grille mounting hole 101, and the metal grille 8 is provided on the inner side of the sound-absorbing box 1, and a sound-absorbing panel 10 is fixedly provided inside the sound-absorbing panel bin 102 to isolate noise. At the same time, the sound-absorbing panel bin 102 is connected to the interior of the sound-absorbing box 1 through a number of evenly distributed sound-absorbing holes 104, and the interior of the sound-absorbing holes 104 is filled with sound-absorbing sponge blocks. The noise generated can also be absorbed by the sound-absorbing sponge blocks on the sound-absorbing holes 104, thereby further reducing the noise.

[0025] Furthermore, in order to facilitate the debugging and maintenance of the diesel engine, Figure 2 、 Figure 5 、 Figure 10 as well as Figure 11As shown, the silent box body 1 is provided with symmetrically distributed sealing plate grooves 103, the sealing plate grooves 103 are adjacent to the front air flow mechanism 2, and a sealing plate 6 is installed inside the sealing plate grooves 103. The upper end of the sealing plate grooves 103 is provided with an upper clamping head 1031, and the lower end is provided with a lower clamping head 1032. The length of the upper clamping head 1031 is greater than the length of the lower clamping head 1032. Sealing plate grooves 103 are provided on both sides of the silent box body 1, and a movable sealing plate 602 is movably connected inside the sealing plate grooves 103. By disassembling and assembling the movable sealing plate 602, the diesel engine can be easily debugged and maintained. The sealing plate 6 includes a support positioning bar 601 and a movable sealing plate 602. The support positioning bar 601 is fixedly arranged at the upper end of the sealing plate groove 103 and inside the upper clamping head 1031 by a number of springs 603. The movable sealing plate 602 is abutted against the support positioning bar 601 and is arranged inside the upper clamping head 1031 and the lower clamping head 1032. The inner side of the movable sealing plate 602 is attached with a sponge sound-absorbing layer 606. The outer side of the movable sealing plate 602 is provided with an installation handle 607. The upper side of the movable sealing plate 602 is fixedly provided with a clamping head 605. The lower side of the support positioning bar 601 is provided with a clamping groove 604 corresponding to the clamping head 605. The clamping head 605 is engaged with the clamping groove 604 to improve the stability of the movable sealing plate 602. The disassembly and assembly operations are as follows: Insert the upper end of the movable sealing plate 602 into the interior of the upper clamping head 1031, and make the clamping head 605 clamped into the interior of the clamping groove 604, then lift the movable sealing plate 602 upwards through the installation handle 607 on the movable sealing plate 602, so that the bottom of the movable sealing plate 602 is clamped into the interior of the lower clamping head 1032, and the installation of the movable sealing plate 602 is completed under the action of the spring 603. The disassembly method is opposite to the above method, so it is convenient to disassemble the movable sealing plate 602, which is convenient for the later maintenance and care of the diesel engine; At the same time, if Figure 7 As shown, symmetrically distributed partition mounting blocks 105 are provided on the inner side surface of the silent box 1, and a battery partition 9 is fixedly provided on the partition mounting block 105. The battery partition 9 is provided with a partition mounting groove 901 that is engaged with the partition mounting block 105. Both sides of the battery partition 9 are sprayed with flame retardant paint. The internal space of the silent box 1 is divided by the battery partition 9 so that the diesel engine and the battery can be placed independently without interfering with each other, thereby improving the service life of the battery. At the same time, the battery partition 9 is easy to install and has a simple structure. An assembly plate 109 is fixedly provided on the outer side surface of the silent box 1 below the sealing plate 6. The silent box 1 is fixed to the chassis of the vehicle body through the assembly plate 109 to improve the stability of the silent box 1.

[0026] Further, if Figure 1 and Figure 2As shown, an electrically connected processor 11 and a temperature sensor 13 are fixedly provided on the side surface inside the silent box 1, the exhaust motor 3, the sealing ring drive motor 5 and the air flow plate rotating motor 701 all establish communication connections with the processor 11, and an air flow sensor 12 is fixedly provided inside the inclined flow channel 106, and the air flow sensor 12 establishes a communication connection with the processor 11. A temperature sensor 13 is fixedly provided inside the silent box 1, and an air flow sensor 12 is provided inside the inclined flow channel 106. When the temperature sensor 13 detects that the temperature is too high and the air flow sensor 12 detects that the flow rate is too low, the information will be pushed to the processor 11, and the processor 11 will immediately start the exhaust motor 3 and the air flow plate rotating motor 701 to increase the air flow rate to achieve rapid cooling. Moreover, when the diesel engine is idle, the air suction hole 203 is sealed by the sealing ring drive motor 5, with a high degree of automation, thereby improving the heat dissipation efficiency.

[0027] like Figures 1-12 As shown, the operating method of the silent box structure of the hybrid diesel generator set provided in this embodiment includes the following steps: Step 1: Installation: By installing the partition mounting groove 901 on the battery partition 9 onto the partition mounting block 105, the interior of the silent box 1 is formed into an engine compartment and a battery compartment, and the silent box 1 is directly covered on the diesel engine and the battery. After adjusting the position, the silent box 1 is fixed by the assembly plate 109; Step 2: Debugging and repairing, by removing the movable sealing plates 602 on both sides of the silent box 1, the diesel engine or battery is inspected and debugged, wherein the disassembly and assembly of the movable sealing plates 602 are as follows: To install, first insert the upper end of the movable sealing plate 602 into the interior of the upper clamping head 1031, and make the clamping head 605 snap into the interior of the clamping slot 604. Then, lift the movable sealing plate 602 upwards through the installation handle 607 on the movable sealing plate 602, so that the bottom of the movable sealing plate 602 snaps into the interior of the lower clamping head 1032. Under the action of the spring 603, the installation of the movable sealing plate 602 is completed. To disassemble, lift the movable sealing plate 602 upwards by installing the handle 607, first separate the bottom of the movable sealing plate 602 from the lower clamping head 1032, and then remove the upper end of the movable sealing plate 602 from the interior of the upper clamping head 1031; Step 3: Heat dissipation operation. During operation, the arc-shaped airflow plate 7 is rotated by starting the airflow plate rotating motor 701 on the arc-shaped airflow plate 7, and at the same time, the sealing ring driving motor 5 is started to make the sealing ring air inlet 401 correspond to the air suction hole 203. After the silent box 1 is in operation, the air flows through the arc-shaped airflow plate 7 at a flow rate greater than the flow rate at the bottom of the silent box 1. Therefore, the air enters the interior of the silent box 1 through the air suction hole 203 on the front air flow mechanism 2 and flows out through the oblique flow channel 106, thereby achieving the purpose of heat dissipation inside the silent box 1. When idling, the temperature sensor 13 detects that the temperature inside the silent box 1 is too high, and pushes the information to the processor 11. The processor 11 pushes the information to the exhaust motor 3, and the heat inside the silent box 1 is exchanged through the exhaust motor 3 to achieve the purpose of heat dissipation; Step 4: Sealing operation, turn off the air flow plate rotating motor 701 to make the arc air flow plate 7 rotate downward and cover the end of the inclined flow channel 106, and at the same time start the sealing ring driving motor 5 to make the sealing ring air inlet 401 away from the air suction hole 203 and seal the air suction hole 203 to reduce the inflow of air.
