It usually adopts special sound insulation materials and structural design, which can effectively absorb and block the noise generated by the diesel generator during operation, greatly reduce the noise level, and reduce the interference to the surrounding environment. For example, multiple layers of sound insulation felt or foam materials may be laid inside the chassis to reduce the propagation and reflection of sound waves;

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1: This embodiment is used to solve the problem that during the use of a traditional diesel generator chassis, due to the use environment and the need for heat dissipation during operation of the diesel generator, the air flow is easily caused by dust accumulation and blockage in the air inlet area, which in turn causes the high temperature generated by the long-term operation of the diesel generator in the chassis to be unable to be effectively discharged, causing hidden dangers to the operation of the diesel generator body; at the same time, the invasion of dust causes the fit between the mechanical parts of the diesel generator body to decrease, and the service life of some precision parts to be reduced, resulting in a large operating noise problem.

[0035] See also Figure 1 - Fig.12As shown, this embodiment is a noise reduction and dust removal chassis for a diesel generator, comprising a base 1, a guide frame 101 is arranged at the top center of the base 1, and a main box body 3 is arranged at the top edge of the base 1, a front cover 2 is arranged at one end of the main box body 3, a control panel 6 is arranged on the outer wall of the front cover 2, and an inner bracket 202 is arranged on the inner wall of the bottom of the front cover 2, a top cover 4 is arranged on the top of the main box body 3, and an exhaust fan 401 extending to the inside of the main box body 3 is arranged at the bottom of the top cover 4, and the other end of the main box body 3 is provided with a front cover 201, and a control panel 6 is arranged on the outer wall of the front cover 2, and an inner bracket 202 is arranged on the inner wall of the bottom of the front cover 2, and a top cover 4 is arranged on the top of the main box body 3. A dust filter box 5 is arranged on the outer wall of the end; a dust exhaust pipe rack 501 is arranged at the bottom of the dust filter box 5, and a separation box 504 is arranged in the middle of the dust filter box 5, a flexible filter ring 505 is arranged inside the separation box 504, and a driving motor 506 is arranged on the side of the flexible filter ring 505, and a dust cleaning mechanism 7 is arranged at the center of the inner circle of the flexible filter ring 505, and the dust cleaning mechanism 7 includes a lifting cylinder 701 and a vertical filter plate 703, and an inclined spray frame 704 is arranged side by side at one end of the vertical filter plate 703;

[0036] The control panel 6 is internally provided with a processor, a data acquisition module, a data analysis module and a component control module; the data acquisition module is used to collect the ambient temperature noise fluctuation value WZz located inside the main box 3 and the air volume delivery reference value FLz located in the dust filter box 5 during the use period of the chassis, and send the ambient temperature noise fluctuation value WZz and the air volume delivery reference value FLz to the data analysis module via the processor; 10h of the chassis use time is set as the time threshold;

[0037] It should be noted that: the environmental temperature noise fluctuation value WZz is expressed as the comprehensive data average value of the environmental temperature difference and the noise difference caused by the diesel generator inside the main box 3 under normal operating conditions obtained within the time threshold. The value of the environmental temperature noise fluctuation value WZz reflects whether the operating environment of the diesel generator inside the main box 3 meets the standards, and the larger the value of the environmental temperature noise fluctuation value WZz, the greater the impact on the operating state of the diesel generator, and the greater the temperature and noise generated. The air volume delivery reference value FLz is expressed as the air volume extracted by the exhaust fan 401 through the dust filter box 5 and delivered to the inside of the main box 3 obtained within the time threshold. In addition, the environmental temperature noise fluctuation value WZz is obtained by jointly collecting the temperature sensor and the noise detection sensor installed inside the main box 3, and the air volume delivery reference value FLz is obtained by collecting the impeller-type air volume sensor installed inside the air supply port 502;

[0038] After receiving the ambient temperature noise fluctuation value WZz and the air volume delivery reference value FLz, the data analysis module immediately analyzes the operating risk of the chassis. The specific analysis process is as follows:

[0039] The ambient temperature noise fluctuation value WZz and the air volume delivery reference value FLz of the chassis within the time threshold are obtained, and the formula The operation risk coefficient R is obtained, wherein a and b are respectively the proportional coefficients of the ambient temperature noise fluctuation value WZz and the air volume delivery reference value FLz, a>b>0, and R is represented as the operation risk coefficient, and the preset operation risk coefficient Y stored and entered is retrieved from the processor for comparison and analysis with the operation risk coefficient R;

[0040] If the operation risk coefficient R ≥ the preset operation risk coefficient Y, it is determined that there is an abnormal risk in the use of the chassis within the time threshold, and a dust cleaning signal is generated. The generated signal is sent to the component control module via the processor. After receiving the dust cleaning signal, the component control module immediately starts the exhaust fan 401 to work;

[0041] The regulating valve controls and closes the air delivery port 502, and the exhaust fan 401 is connected to the jet pipe 707, the inclined spray rack 704, the jet rack 510 and the outside of the dust filter box 5 through pipe fittings and the regulating valve, so as to temporarily cut off the internal transmission of external air and extract a small amount of external air through additional pipelines;

[0042] The expansion airbag 512 is concave, causing the inner walls of both sides of the separation box 504 to present channels directly connected to the dust exhaust pipe rack 501, and the lifting cylinder 701 drives the partition plate 702 to slide downward until it passes over the top of the expansion airbag 512, keeping the top inner circle of the flexible filter ring 505 connected to the dust exhaust pipe rack 501;

[0043] The vibration motor drives the vertical filter plate 703 and the oblique spray frame 704 to vibrate at high frequency through the vibration arc frame 705 and the vibration support frame 706. During the high-frequency vibration of the vertical filter frame, the impurities attached to it are caused to fall off. The vibration support frame 706 is connected to the oblique spray frame 704 and is movably connected to the inner wall of the top of the flexible filter ring 505. The vibration amplitude of the vibration support frame 706 is intermittently in contact with the inner wall of the flexible filter ring 505, so that the part of one end of the flexible filter ring 505 located between the main roller 508 and the auxiliary roller 507 is continuously in a high-frequency vibration state, which effectively ensures that the impurities and dust attached to the flexible filter ring 505 are separated.

[0044] During the high-frequency vibration of the vertical filter plate 703, the air jet pipe 707 guides the airflow provided by the exhaust fan 401 to blow from top to bottom toward the vertical filter plate 703, and the mechanical vibration causes the dust to fall. At the same time, the inclined spray rack 704 cooperates with the local vibration of the flexible filter ring 505 to clean the impurities attached to the inner and outer surfaces of the flexible filter ring 505. Under the influence of the continuous airflow sprayed by the inclined spray rack 704, the excess airflow is caused to flow downward in the spray direction of the inclined spray rack 704, and is mixed with the dust-containing gas cleaned by the vertical filter plate 703. Under the guidance of the airflow and the diversion of the partition 702, the dust-containing gas is caused to flow along the channel between the expansion airbag 512 and the dust exhaust pipe rack 501, so that the dust impurities retained in the flexible filter ring 505 are quickly cleaned;

[0045] When the expansion airbag 512 is deflated, the auxiliary airbags disposed at the bottom of the expansion airbag 512 near the multiple groups of auxiliary rollers 507 are deflated at the same time, and the dust generated by the continuous brushing of the flexible filter ring 505 by the electric brush 511 falls off, and combined with the influence of the airflow continuously sprayed by the jet frame 510, the air pressure in the area continues to increase, and most of the dust-containing gas overflows along the connection port between the bottom of the separation box 504 and the dust exhaust pipe rack 501, and a small amount of dust-containing gas located at the inner circle of the bottom of the flexible filter ring 505 is discharged along the channel connected to the dust exhaust pipe rack 501 after the auxiliary airbag is deflated;

[0046] If the operation risk factor R is less than the preset operation risk factor Y, no signal is generated.

[0047] Embodiment 2: This embodiment is a noise reduction and dust removal chassis for a diesel generator. The guide frames 101 are symmetrically arranged on both sides of the center of the top of the base 1, and a plurality of groups of heat-conducting columns 105 are arranged through the center of the top of the base 1. A plurality of groups of through holes 102 are arranged on the top of the base 1 close to the dust filter box 5. A gas dispersion frame 103 is arranged at the bottom of both sides of the base 1, and a discrete channel 104 connected to the through hole 102 is arranged on the top of the gas dispersion frame 103; the entire front cover 2 is pulled out of the main box body 3 by pulling the handle on the front cover 2, and the inner bracket 202 slides with the guide frame 101 through the slide groove 204, and when folded The support frame 205 is unfolded after being freed from the restriction of the bottom frame. The bottom of the folding support frame 205 is provided with a universal wheel in contact with the ground. The inner bracket 202 is lifted up in the air by cooperating with the sliding groove 204 and the guide frame 101. The diesel generator is assembled on the inner bracket 202 through the cushion 203. The handle is pushed by external force, so that the diesel generator moves into the main box body 3 along with the inner bracket 202 and the front cover 2, and the front cover 2 closes the main box body 3. A soundproof cavity 301 is opened in the center of the inner wall of the main box body 3, and a plurality of air outlets 302 are arranged on the inner wall of one end of the main box body 3 close to the dust filter box 5.

[0048] The diesel generator is started through the control panel 6. When the noise generated by the diesel generator is diffused into the main box 3, the noise is firstly absorbed by the sound insulation cavity 301 and the sound-absorbing cotton filled in the sound insulation cavity 301 to reduce the noise transmission. Secondly, a cavity is formed between the rear partition 702 and the front cover 2, and sound insulation cotton is arranged in the cavity to absorb the noise inside the main box 3 for a second time. An air dispersion mesh plate 201 is arranged in the middle of the end face of the front cover 2, a rear sealing plate 206 is arranged on the inner wall of the front cover 2, a plurality of groups of soft pads 203 are arranged on the top of the inner bracket 202, slide grooves 204 are symmetrically arranged on both sides of the bottom of the inner bracket 202, and a folding support frame 205 is arranged on the inner wall of the slide groove 204;

[0049] A plurality of groups of air intake grilles 503 close to the separation box 504 are arranged on the outer wall at the top of the dust filter box 5, and an air guide gasket 509 facing the separation box 504 is arranged side by side at one end of the air intake grilles 503, a main roller 508 sleeved with the top of the flexible filter ring 505 is arranged at the output end of the driving motor 506, and a plurality of groups of auxiliary rollers 507 are arranged below the main roller 508, an injection rack 510 is arranged between the plurality of groups of auxiliary rollers 507, and an electric brush 511 is arranged at the bottom of the injection rack 510, an air delivery port 502 connected to the exhaust fan 401 is arranged at the top of one end of the dust filter box 5, and a regulating valve is arranged inside the air delivery port 502, and expansion air bags 512 are arranged on the inner walls on both sides of the separation box 504;

[0050] The exhaust fan 401 is started during the use of the diesel generator. The exhaust fan 401 draws external air along the dust filter box 5 through the air supply port 502. The external air enters the dust filter box 5 after being screened and filtered by the air intake grille 503. The external air entering is first guided by the air guide gasket 509 to change its direction of flowing downward. When the external air flows close to the top of the separation box 504, it is pulled by the exhaust fan 401 to flow upward. In this process, the external air with a reverse flow first contacts the flexible filter ring 505, and then contacts multiple groups of vertical filter plates 703 after passing through the flexible filter ring 505. Then, it enters the main box 3 along the air supply port 502, and the diversion value is adjusted by the regulating valve to the air outlet 302. The air outlet 302 guides the clean air to blow to the front cover 2 along the inside of one end of the main box 3, thereby realizing a through-the-hall wind flow structure.

[0051] The lifting cylinder 701 is hinged with partitions 702 at both ends, a vibrating arc frame 705 is arranged on the top of the vertical filter plate 703, and a vibrating support frame 706 connected to the oblique spray frame 704 is arranged side by side at one end of the vibrating arc frame 705, a plurality of groups of spray pipes 707 are inserted through the inner wall of the vertical filter plate 703, and a vibrating motor is arranged on one side of the top of the vibrating arc frame 705;

[0052] Under normal conditions, the flexible filter ring 505 is driven by the driving motor 506, the main roller 508 and the auxiliary roller 507 to rotate at a constant speed, and the dust and impurities intercepted and filtered near the air guide gasket 509 are carried to the jet rack 510 area. First, the electric brush 511 brushes, rubs and vibrates the inner wall to cause some dust to fall off. Then, the jet rack 510 uses a close-range jet airflow to hit the inner wall of the flexible filter ring 505, causing the dust and impurities adhered to its surface to fall off one after another and move toward the dust exhaust pipe rack 501. During this period, the top and bottom of the flexible filter ring 505 are separated by multiple groups of partitions 702 horizontally expanded, causing the clean air after external suction and filtration to move along the flexible filter ring The top area of ​​505 flows downstream to the air delivery port 502, and the air containing a large amount of dust and impurities in the bottom area of ​​the flexible filter ring 505 is cleaned and transmitted along the dust exhaust pipe rack 501. The bottom of the dust exhaust pipe rack 501 is connected to the perforation 102, and guides the dust-containing impurity airflow to be dispersed into the diffuser 103, and is diverted and discharged through the discrete channels 104. The top of the heat-conducting column 105 extends to the main box 3 to absorb the heat generated by the operation of the diesel generator, and guides it to the bottom of the heat-conducting column 105, and the bottom of the heat-conducting column 105 extends to the discrete channels 104, and the heat diffused on its surface is guided to be discharged through the dust-containing impurity airflow, thereby realizing the reuse of exhaust gas and effectively controlling the temperature in the main box 3.

[0053] It can be seen from the combination of Example 1 and Example 2 that it is possible to judge whether the chassis is qualified for external dust filtration during the use of the diesel generator based on the feedback of data parameters such as temperature and noise generated by the diesel generator running in the chassis, thereby avoiding dust accumulation causing blockage of cooling airflow, and the chain reaction of dust covering the internal diesel generator and related precision control instruments. In addition, the accumulated dust in the filtering structure can be processed in time to achieve smooth air flow in the chassis, reduce environmental interference with the operation of the diesel generator, and then reduce the noise generated by the abnormal operation of the diesel generator itself and the spread of noise caused by the abnormal air environment, thereby improving the use efficiency of the diesel generator in the chassis and the life of components.

The value of the ambient temperature noise fluctuation value WZz reflects whether the operating environment of the diesel generator in the main box (3) meets the standard. The larger the value of the ambient temperature noise fluctuation value WZz, the greater the impact on the operating state of the diesel generator, and the greater the temperature and noise generated. The air volume delivery reference value FLz is represented by the air volume extracted by the exhaust fan (401) through the dust filter box (5) and delivered to the inside of the main box (3) obtained within the time threshold. After receiving the ambient temperature noise fluctuation value WZz and the air volume delivery reference value FLz, the data analysis module immediately analyzes the operation risk of the chassis. The specific analysis process is as follows: the ambient temperature noise fluctuation value WZz and the air volume delivery reference value FLz of the chassis within the time threshold are obtained, the operation risk coefficient R is obtained by the formula, and the preset operation risk coefficient Y stored and entered is retrieved from the processor for comparison and analysis with the operation risk coefficient R; If the operation risk coefficient R ≥ the preset operation risk coefficient Y, it is determined that there is an abnormal risk in the use of the chassis within the time threshold, a dust cleaning signal is generated, and the generated signal is sent to the component control module via the processor. After receiving the dust cleaning signal, the component control module immediately operates the exhaust fan (401); If the operation risk factor R is less than the preset operation risk factor Y, no signal is generated.
