Description

Technical Field

[0001] This invention belongs to the field of generator set technology, specifically a noise reduction device for a container generator set and the generator set thereof. Background Technology

[0002] Container generator sets have been widely used in various fields such as industrial production, emergency rescue, construction sites, commercial activities, and power supply in remote areas. In factories, mines, oil fields and other places, they serve as primary or backup power sources to ensure the continuous operation of production equipment and avoid economic losses caused by power outages. After natural disasters or emergencies, they can quickly reach disaster areas to provide emergency power for rescue equipment, communication base stations and temporary medical facilities, thus buying time for disaster relief.

[0003] In the prior art, patent application document "CN108104944A" discloses "a containerized generator set"; it includes a container shell, and an oil tank, a controller, and at least two generator sets are installed inside the container shell. The control terminals of all generator sets are connected to the controller signal, and the power unit of all generator sets is an engine. The oil tank is connected to the oil inlet of each engine through oil pipes. This invention switches the working state of the generator sets through the controller, so that it can provide uninterrupted power supply and meet the working conditions that require maintenance and downtime of a generator set. The use of a container shell solves the technical problems of inconvenient transportation and large installation space requirements. The built-in oil tank, especially to meet the needs of long-term operation, has a large capacity to ensure the oil demand of the unit for long-term operation.

[0004] The aforementioned "container generator set" still has some drawbacks. For example, the noise reduction methods of existing container generator sets mostly adopt simple container sealing or single-layer sound insulation material wrapping. Although this method can reduce noise transmission to a certain extent, it will also lead to poor air circulation inside the container, and the heat generated by the generator set cannot be dissipated in time, which will cause problems such as equipment overheating, reduced operating efficiency, accelerated component aging, and further increase noise. To address this issue, a noise reduction device for container generator sets and the generator set thereof are proposed. Summary of the Invention

The specific calculation and control logic is as follows: A1. Real-time parameter acquisition: The real-time operating temperature T of the generator set is acquired through a temperature sensor; the real-time pressure difference ΔP between the two sides of the top filter is acquired through a differential pressure sensor; and the real-time noise value N inside the side protective cover is acquired through a noise sensor. A2. Calculation of the degree of clogging of the top filter screen: Define the filter screen clogging coefficient K, K=ΔP / ΔP0, where ΔP0 is the standard pressure difference of the top filter screen under clean conditions. When K<0.3, it is judged as clean; when 0.3≤K<0.7, it is judged as slightly clogged; when K≥0.7, it is judged as heavily clogged. A3. Calculation of drive motor speed control: The real-time speed V of the drive motor (unit: r / min) is calculated based on the following formula: V=V0×[1+0.2×(T-T0) / T0+0.3×K], where V0 is the reference speed of the drive motor, T0 is the normal operating temperature threshold of the generator set, and the adjustment range of V is limited to 0.8V0≤V≤1.5V0; A4.

Control Execution: When the calculated V and Q exceed the corresponding adjustment range, the algorithm automatically triggers limit control to limit V and Q to the maximum and minimum thresholds respectively; when K≥0.7 and the duration≥5min, the algorithm triggers the drive motor speed to increase to 1.5V0 and runs continuously for 10min to enhance the cleaning effect of the flexible cleaning brush. After cleaning is completed, the speed returns to the real-time speed calculated by the formula.

[0015] A containerized generator set, comprising: Generator set; Used to reduce noise in generator sets.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1) By connecting the support bracket, the drive motor can be firmly supported on the top of the air outlet connection frame. During the rotation of the transmission rod, the ventilation fan blades will be rotated synchronously. The rotating ventilation fan blades will generate a stable airflow along the inner side of the air outlet connection frame, blowing the air outside the side protective cover into the side protective cover along the air inlet connection frame, thereby realizing the circulation of air inside and outside the noise reduction protective frame, reducing the accumulation of heat generated by the generator set in the box, and at the same time, the airflow can help weaken the transmission of noise, taking into account both ventilation and basic noise reduction effects, and reducing the impact of high temperature environment on the operating stability of the generator set. 2) By utilizing the dust filter mechanism, while maintaining airflow within the side protective cover and noise reduction protective frame and ensuring the heat dissipation requirements of the generator set, it can effectively intercept external dust particles from entering the noise reduction protective frame, prevent dust from adhering to the surface of the generator set's components, reduce component wear and failure rate, improve the protection of the container generator set, and indirectly extend the service life of the generator set. 3) The rotating cleaning transmission plate will drive the flexible cleaning brush to rotate. The rotating flexible cleaning brush will rotate and clean along the surface of the top filter screen, and sweep away the dust particles accumulated on the surface of the top filter screen. After cleaning, the top filter screen can maintain good filtration effect and ventilation efficiency, avoid dust clogging the filter screen, which will lead to poor ventilation and reduced noise reduction effect. At the same time, it reduces the frequency of manual cleaning of the filter screen and reduces maintenance costs. 4) After the ventilation fan blades rotate and draw outside air into the side protective cover, the air passes through multiple heat exchange fins. The air entering the side protective cover comes into contact with the cold surface of the heat exchange fins and undergoes heat exchange. The air loses heat during the contact process and is cooled. The cooled air is then blown into the noise reduction and protection frame to precisely cool the generator set in operation, effectively control the generator set's operating temperature, and avoid problems such as increased noise and component aging caused by high temperatures. At the same time, the cooling mechanism and the ventilation mechanism work together to further optimize noise reduction performance while ensuring the cooling effect, improve the stability of the generator set in high-temperature and dusty environments, and extend the overall service life of the generator set and noise reduction device.

[0020] It should be noted that by utilizing the dust filter mechanism 5, while maintaining airflow within the side protective cover 401 and the noise reduction protective frame 3 and meeting the heat dissipation requirements of the generator set 2, it can effectively intercept external dust particles from entering the noise reduction protective frame 3, prevent dust from adhering to the surface of the generator set 2 components, reduce component wear and failure rate, improve the protection of the container generator set 2, and indirectly extend the service life of the generator set 2.

[0021] In this embodiment, a support bracket 404 is fixedly connected to the top of the air outlet connection frame 403, a drive motor 405 is fixedly connected to one side of the support bracket 404, a transmission rod 406 is fixedly connected to the output shaft of the drive motor 405, and a ventilation fan blade 407 is fixedly connected to the bottom end of the transmission rod 406.

[0022] It should be noted that the rotating ventilation fan blades 407 will generate a stable airflow along the inner side of the air outlet connection frame 403, blowing the air outside the side protective cover 401 into the side protective cover 401 along the air inlet connection frame 402, thereby realizing the circulation of air inside and outside the noise reduction protective frame 3, reducing the accumulation of heat generated by the generator set 2 in the box, and at the same time, the airflow can help weaken the transmission of noise, taking into account both ventilation and basic noise reduction effects.

[0023] In this embodiment, the dust filter mechanism 5 includes a filter protection cylinder 501, a filter connecting plate 502, and a top filter screen 503. The filter protection cylinder 501 is fixedly connected to the top of the air outlet connecting frame 403, the filter connecting plate 502 is fixedly connected to the top of the filter protection cylinder 501, and the top filter screen 503 is fixedly connected to the inner side of the filter connecting plate 502.

[0024] It should be noted that, through the function of the top filter 503 inside the filter connection plate 502, dust particles and other objects in the incoming airflow can be filtered and blocked, and the dust particles and other objects are intercepted on the surface of the top filter 503. After the filtered air is blown into the side protective cover 401, it will be discharged along the inside of the return air connecting frame 504, maintaining the air circulation in the noise reduction protective frame 3 and ensuring the continuous heat dissipation of the generator set 2.

[0025] In this embodiment, a return air connecting frame 504 is provided at the bottom of the side protective cover 401, a bottom protective frame 505 is fixedly connected to the inner side of the return air connecting frame 504, a dust collection tray 507 is fixedly connected to the top of the bottom protective frame 505, a bottom filter screen 506 is fixedly connected to the inner side of the bottom protective frame 505, and a side filter screen 508 is fixedly connected to one side of the noise reduction protective frame 3.

[0026] It should be noted that after the gas is blown into the side protective cover 401 and completes heat exchange and noise reduction, it will be discharged along the inner side of the return air connecting frame 504, maintaining the air circulation within the noise reduction protective frame 3. The bottom filter 506 installed on the inner side of the return air connecting frame 504 can provide secondary blocking for residual dust particles or insects in the airflow. The bottom filter 506 is fixed to the inner side of the return air connecting frame 504 through the bottom protective frame 505, and achieves a third dust filtration through the side filter 508, further reducing the impact of particulate matter entering the noise reduction protective frame 3 on the generator set 2. At the same time, the dust collection tray 507 fixed on the top of the bottom protective frame 505 can collect the dust that falls during cleaning, facilitating subsequent maintenance and cleaning.

[0027] In this embodiment, the filter cleaning mechanism 6 includes a fixed bracket 601, a rotating bearing ring 602, and a cleaning transmission plate 603. The fixed bracket 601 is fixedly connected to the top of the filter protection cylinder 501, and the rotating bearing ring 602 is movably connected to the bottom of the fixed bracket 601. The inner side of the rotating bearing ring 602 is movably connected to the surface of the transmission rod 406.

[0028] It should be noted that the rotating transmission rod 406 is movably sleeved on the bottom of the fixed bracket 601 through the rotating bearing ring 602, and the fixed bracket 601 provides limiting support for the rotating bearing ring 602 to ensure the stability of the transmission rod 406 during rotation, avoid additional noise caused by vibration, and ensure the normal operation of the cleaning mechanism.

[0029] In this embodiment, a cleaning transmission plate 603 is fixedly connected to the surface of the transmission rod 406, and a flexible cleaning brush 604 is fixedly connected to the bottom of the cleaning transmission plate 603.

[0030] It should be noted that the rotating cleaning transmission plate 603 will drive the flexible cleaning brush 604 to rotate. The rotating flexible cleaning brush 604 will rotate and clean along the surface of the top filter screen 503, and sweep away the dust particles accumulated on the surface of the top filter screen 503. After cleaning, the top filter screen 503 can maintain good filtration effect and ventilation efficiency, avoid poor ventilation and reduced noise reduction effect caused by dust clogging the filter screen, and at the same time reduce the frequency of manual cleaning of the filter screen and reduce maintenance costs.

[0031] In this embodiment, a cooling and noise reduction mechanism 7 is provided on the inner side of the side protective cover 401. The cooling and noise reduction mechanism 7 includes a coolant storage tank 701, an inlet connecting pipe 702, and an inlet delivery pump 703. The coolant storage tank 701 is fixedly connected to the outer side of the side protective cover 401. The inlet connecting pipe 702 is fixedly connected to the top of the coolant storage tank 701. An inlet delivery pump 703 is provided on one side of the inlet connecting pipe 702. A cooling heat exchange plate 704 is movably connected to one side of the inlet delivery pump 703. A return connecting pipe 705 is fixedly connected to the bottom of the cooling heat exchange plate 704. A return delivery pump 706 is provided on one side of the return connecting pipe 705. One side of the return delivery pump 706 is movably connected to the bottom of the coolant storage tank 701.

[0032] It should be noted that by starting the return liquid transfer pump 706, the coolant in the cooling heat exchange plate 704 can flow back to the coolant storage tank 701 along the return liquid connecting pipe 705. Through the coordinated drive of the inlet liquid transfer pump 703 and the return liquid transfer pump 706, the coolant can be driven to circulate in the coolant storage tank 701 and the cooling heat exchange plate 704 through the connection between the inlet liquid connecting pipe 702 and the return liquid connecting pipe 705. This allows for continuous cooling of the cooling heat exchange plate 704 in the opposite protective cover 401, providing a guarantee for subsequent airflow heat exchange and auxiliary noise reduction.

[0033] In this embodiment, there are two coolant storage tanks 701, and heat dissipation fins 707 are fixedly connected to both sides of the two coolant storage tanks 701, and there are multiple heat dissipation fins 707.

[0034] It should be noted that the coolant in the coolant storage tank 701 will continuously dissipate heat through multiple heat dissipation fins 707. Multiple heat dissipation fins 707 can effectively increase the heat dissipation area of ​​the coolant storage tank 701, ensuring that the coolant maintains a low temperature during circulation, ensuring the continuous and stable operation of the cooling and noise reduction mechanism 7, and avoiding a decrease in cooling effect due to the increase in coolant temperature.

[0035] In this embodiment, a heat-conducting heat exchange plate 708 is fixedly connected to one side of the cooling heat exchange plate 704. There are multiple heat-conducting heat exchange plates 708, and all multiple heat-conducting heat exchange plates 708 are arranged in parallel along the inner side of the cooling heat exchange plate 704. The side protective cover 401 has four pipe connection holes 709 on both sides, and the inner sides of the four pipe connection holes 709 are respectively set on the surface of the liquid inlet connection pipe 702 and the liquid return connection pipe 705.

[0036] It should be noted that after the ventilation fan blades 407 rotate to draw outside air into the side protective cover 401, the air passes through multiple heat exchange fins 708. The air entering the side protective cover 401 comes into contact with the cold surfaces of the heat exchange fins 708 and undergoes heat exchange. During this contact process, the air loses heat and is cooled. The cooled air is then blown into the noise reduction and protection frame 3 to precisely cool the generator set 2 during operation, effectively controlling the operating temperature of the generator set 2 and avoiding problems such as increased noise and component aging caused by high temperatures. At the same time, the cooling mechanism and the ventilation mechanism work together to further optimize noise reduction performance while ensuring the cooling effect and improving the efficiency of the generator set. The stability of the motor unit 2 during continuous use in high-temperature and dusty environments is ensured by the opening of the pipe connection hole 709. This allows the inlet pipe 702 to stably transfer the coolant in the coolant storage tank 701 to the cooling heat exchange plate 704, and the return pipe 705 to transfer the heated coolant in the cooling heat exchange plate 704 back to the coolant storage tank 701, thus achieving coolant circulation. At the same time, the pipe connection hole 709 ensures that the inlet pipe 702 and the return pipe 705 pass smoothly through the inner and outer sides of the side protective cover 401, preventing pipe bending or damage from affecting coolant circulation and ensuring the normal operation of the cooling and noise reduction mechanism 7.

[0037] Example 2 This embodiment 2 provides a noise reduction method for container generator sets, which is used to further explain the working process or principle of the container generator set noise reduction device and its generator set provided in embodiment 1 above. The specific method is as follows: A noise reduction device for a container generator set and the generator set thereof, comprising the following steps: S1. Start the drive motor 405 and drive the transmission rod 406 to rotate. Through the connection of the support bracket 404, the drive motor 405 can be stably supported on the top of the air outlet connection frame 403. During the rotation of the transmission rod 406, the ventilation fan blades 407 will rotate synchronously. The rotating ventilation fan blades 407 will generate a stable airflow along the inner side of the air outlet connection frame 403, blowing the air outside the side protective cover 401 into the side protective cover 401 along the air inlet connection frame 402, thereby realizing the circulation of air inside and outside the noise reduction protective frame 3, reducing the accumulation of heat generated by the generator set 2 in the box. At the same time, the airflow can help weaken the transmission of noise, taking into account both ventilation and basic noise reduction effects, and reducing the impact of high temperature environment on the operating stability of the generator set 2. S2. When gas enters the side protective cover 401 along the air inlet connecting frame 402, the rotating fan blades 407 blow the air along the filter connecting plate 502 into the inner side of the filter protective cylinder 501. The top filter 503 inside the filter connecting plate 502 filters and blocks dust particles in the incoming airflow, trapping them on the surface of the top filter 503. The filtered gas, after entering the side protective cover 401, is discharged along the inner side of the return air connecting frame 504, maintaining air circulation within the noise reduction protective frame 3. The bottom filter 50 is located inside the return air connecting frame 504. 6 can provide secondary blocking for residual dust particles or insects in the airflow. The bottom filter screen 506 is fixed to the inside of the return air connecting frame 504 through the bottom protective frame 505, and the dust collected by the dust collection tray 507 fixed at the top of the bottom protective frame 505 is used to collect the dust that falls during cleaning, which is convenient for subsequent maintenance and cleaning. At the same time, the side filter screen 508 achieves a third dust filtration, further reducing the impact of particulate matter entering the noise reduction protective frame 3 on the generator set 2. By using the dust filtration mechanism 5, the generator set 2 is effectively protected and its protection is improved while maintaining the airflow in the side protective cover 401 and the noise reduction protective frame 3. S3. During the rotation of the transmission rod 406 driven by the drive motor 405, the rotating transmission rod 406 is movably connected to the bottom of the fixed bracket 601 through the rotating bearing ring 602. The fixed bracket 601 provides limiting support for the rotating bearing ring 602, ensuring the stability of the transmission rod 406 during rotation and avoiding additional noise caused by vibration. During the rotation of the transmission rod 406, the cleaning transmission plate 603 will be rotated synchronously. The rotating cleaning transmission plate 603 will drive the flexible cleaning brush 604 to rotate. The rotating flexible cleaning brush 604 will rotate and clean along the surface of the top filter screen 503, sweeping away the dust particles accumulated on the surface of the top filter screen 503. After cleaning, the top filter screen 503 can maintain good filtration effect and ventilation efficiency, avoiding poor ventilation and reduced noise reduction effect caused by dust clogging the filter screen. At the same time, it reduces the frequency of manual cleaning of the filter screen and reduces maintenance costs. S4. During the process of ventilation and auxiliary noise reduction within the side protective cover 401 and noise reduction protective frame 3 while the ventilation fan blades 407 rotate, the inlet pump 703 is started. The inlet pump 703 draws the coolant from the coolant storage tank 701 along the inlet connecting pipe 702 to the cooling heat exchange plate 704. After the coolant continues to flow downwards within the cooling heat exchange plate 704, the return pump 706 is started. The return pump 706 draws the heated coolant from the cooling heat exchange plate 704 along the return connecting pipe 706. 5. The coolant flows back into the coolant storage tank 701. Driven by the combined action of the inlet pump 703 and the return pump 706, the coolant circulates through the connection between the inlet pipe 702 and the return pipe 705, circulating within the coolant storage tank 701 and the cooling heat exchange plate 704. This allows for continuous cooling via the cooling heat exchange plate 704 within the opposite protective cover 401. The two cooling heat exchange plates 704 are connected by heat-conducting heat exchange fins 708, allowing for continuous cooling of multiple heat-conducting heat exchange fins 708. The system cools the generator set 2, and the coolant in the coolant storage tank 701 continuously dissipates heat through multiple heat dissipation fins 707. The multiple heat dissipation fins 707 can effectively increase the heat dissipation area of ​​the coolant storage tank 701, ensuring that the coolant maintains a low temperature during circulation. At this time, after the ventilation fan blades 407 rotate to draw the outside air into the side protective cover 401, the air will pass through multiple heat-conducting heat exchange fins 708. The air entering the side protective cover 401 will come into contact with the cold surface of the heat-conducting heat exchange fins 708 and undergo heat exchange. The air loses heat during the contact process and achieves cooling. The cooled air will be blown into the noise reduction and protection frame 3 to precisely cool the generator set 2 during operation, effectively control the operating temperature of the generator set 2, and avoid problems such as increased noise and component aging caused by high temperature. At the same time, the cooling mechanism works in conjunction with the ventilation mechanism, filtration mechanism, and cleaning mechanism to achieve integrated protection of noise reduction, dust prevention, and cooling, improve the stability of the generator set 2 in high temperature and dusty environment, and extend the overall service life of the generator set 2 and the noise reduction device. Example 3 A noise reduction method for container generator sets utilizes a container generator set noise reduction device and further includes an intelligent control algorithm. This algorithm dynamically adjusts the operating parameters of the drive motor 405, the inlet pump 703, and the return pump 706 based on the real-time operating temperature of the generator set 2, the real-time clogging degree of the top filter 503, and the noise level inside the side protective cover 401. The specific calculation and control logic is as follows: A1. Real-time parameter acquisition: The real-time operating temperature T of generator set 2 is acquired by temperature sensor, the real-time pressure difference ΔP on both sides of top filter screen 503 is acquired by differential pressure sensor, and the real-time noise value N inside side protective cover 401 is acquired by noise sensor. A2. Calculation of the degree of clogging of the top filter screen 503: Define the filter screen clogging coefficient K, K=ΔP / ΔP0, where ΔP0 is the standard pressure difference of the top filter screen 503 under clean conditions. When K<0.3, it is judged as clean; when 0.3≤K<0.7, it is judged as slightly clogged; when K≥0.7, it is judged as heavily clogged. A3. Calculation of speed control for drive motor 405: The real-time speed V (unit: r / min) of drive motor 405 is calculated based on the following formula: V=V0×[1+0.2×(T-T0) / T0+0.3×K], where V0 is the reference speed of drive motor 405, T0 is the normal operating temperature threshold of generator set 2, and the adjustment range of V is limited to 0.8V0≤V≤1.5V0; A4. Coolant circulation rate control calculation: The real-time coolant circulation rate Q is calculated based on the following formula: Q=Q0×[1+0.4×(T-T0) / T0-0.1×(N-N0) / N0], where Q0 is the coolant reference circulation rate, N0 is the normal noise threshold inside the side shield (401), and the adjustment range of Q is limited to 0.6Q0≤Q≤1.4Q0; A5. Control Execution: When the calculated V and Q exceed the corresponding adjustment range, the algorithm automatically triggers limit control to limit V and Q to the maximum and minimum thresholds respectively; when K≥0.7 and the duration≥5min, the algorithm triggers the drive motor 405 to increase the speed to 1.5V0 and run continuously for 10min to enhance the cleaning effect of the flexible cleaning brush 604. After cleaning is completed, the speed is restored to the real-time speed calculated by the formula.

[0038] By collecting real-time data on the generator set's operating temperature, pressure difference across the top filter, and noise level inside the side protective cover using temperature, differential pressure, and noise sensors, the filter clogging coefficient is calculated. Based on a preset formula, the drive motor speed and coolant circulation rate are dynamically adjusted, while threshold limit control is implemented. Furthermore, enhanced cleaning is triggered when the filter is severely clogged. This enables the coordinated and intelligent operation of noise reduction, dust prevention, and cooling mechanisms, ensuring the generator set's operational stability in high-temperature and dusty environments, reducing maintenance costs, and extending equipment lifespan. A containerized generator set, comprising: Generator set 2; A noise reduction device for container generator sets is used to reduce the noise of generator set 2.
