Description

Technical Field

[0001] The present invention relates to the technical field of generators, and in particular to an air-cooled diesel generator set. Background Art

[0002] A diesel generator set is a device that combines a diesel engine with a generator set. The diesel engine generates power by burning diesel, which drives a generator to generate electricity, converting chemical energy into electrical energy. It is often used for emergency backup power, field operations, and other locations where there is no mains power or the mains power is unstable.

[0003] Chinese patent publication number CN221722909U discloses an air-cooled diesel generator set; technical problem: When a traditional air-cooled diesel generator set is in operation, a lot of oil pollution will be generated around it. After long-term use, the oil pollution will stick to the air-cooling structure, thereby affecting the normal heat dissipation of the diesel generator set; technical solution: An air-cooled diesel generator set includes a base, an air-cooling component, a cleaning component, a washing component, a guide component, a control component, a support component and a diesel generator set.

[0004] However, when existing generator sets operate in a humid environment, moisture can intrude into the equipment, causing corrosion and short circuits in electrical components, thus affecting equipment stability and lifespan.

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0039] It should be noted that the above-mentioned diesel generator equipment 4 is a conventional diesel-driven generator set. This structure has been widely used in the prior art. In the present invention, it is only used to realize the function of generating electricity and using the rotating rotor to drive the fan 7 to rotate. Its internal structure, operating principle, wiring, and control method are no longer described in detail.

[0040] Further, in order to achieve dust removal and dehumidification of the inhaled air, to avoid, refer to Figure 3 The dust-proof and dehumidification structure 3 includes a shell 31 fixedly connected to the front inner surface of the shielding box 2 and tightly attached to the rear end of the isolation net 6. A dust-proof component 32 is provided at the front inner surface of the shell 31, and a dehumidification component 33 tightly attached to the rear side of the dust-proof component 32 is provided in the middle inner surface of the shell 31. A uniform wind plate 34 connected to the air duct structure 5 is symmetrically provided on the left and right sides of the rear inner surface of the shell 31. A connecting port 35 connected to the air duct structure 5 is provided on the lower side of the rear inner surface of the shell 31, and an air outlet 36 connected to the air duct structure 5 is provided on the upper inner surface of the shell 31.

[0041] During the operation of this embodiment, the diesel generator equipment 4 is first isolated from the outside air by the sealed shielding box 2 to reduce the intrusion of moisture. At the same time, a dehumidification component 33 is provided to remove moisture from the inhaled air, reduce the corrosion of internal components by moisture, and discharge the separated moisture to the outside of the box; further, the dust and particles in the inhaled air are separated by the dustproof component 32 to reduce the entry of large particles of dust. The dustproof component 32 can also regularly clean the dust on the heat sink through automatic cleaning to ensure the air intake; at the same time, the air flow efficiency is improved by the action of the air duct structure 5, the heat dissipation area is increased, and the heat dissipation efficiency is improved, the heat dissipation effect is enhanced, and the temperature of the equipment is ensured to be stable under high load, avoiding performance degradation and safety hazards caused by overheating.

[0042] Embodiment 2. Based on embodiment 1, this embodiment utilizes the function of the filter 325 to intercept the dust in the inhaled air, and through the cooperation of the cable 323, the winding shaft 322 and the driving motor 321, drives the self-cleaning component 326 to slide up and down on the surface of the filter 325 under the limit of the slide groove 324, and the cleaning brush 3264 provided in the self-cleaning component 326 cleans the dust on the surface of the filter 325 and sends it to the installation box 3261 for temporary storage. Through the cooperation of the support column 3266 and the V-shaped plate 3265, the dust is sent to the outside through the connecting groove 1 327, thereby reducing the accumulation of dust on the surface of the filter 325, avoiding the dust from affecting the operating stability of the diesel generator equipment 4, and also ensuring the air intake volume and the stability of the heat dissipation efficiency, thereby improving the stability of the equipment.

[0043] Specifically, in order to achieve the treatment of dust in the inhaled air and reduce the impact of dust on internal equipment, refer to Figure 4 The dustproof component 32 includes a filter screen 325 fixedly connected to the inner surface of the shell 31. The inner surface of the shell 31 located in front of the filter screen 325 is symmetrically provided with a slide groove 324. The inner surface of the slide groove 324 is slidably connected with a self-cleaning component 326. The upper end of the base 1 located below the self-cleaning component 326 is provided with a connecting groove 327.

[0044] The filter 325 is a conventional filter that can block the dust in the air inhaled by the fan 7 and make it stay in the front of the filter 325. However, under long-term operation, a large amount of dust will inevitably accumulate on the surface of the filter 325. This dust will be blocked on the surface of the filter 325, thereby causing the air intake to decrease, affecting the heat dissipation effect of the diesel generator equipment 4.

[0045] Furthermore, in order to clean the dust intercepted on the filter 325 and avoid the filter 325 from being overly thickly accumulated with dust, which may cause the air flow to decrease and affect the heat dissipation and cooling effect, refer to Figure 5 and Figure 6The self-cleaning component 326 includes a mounting box 3261, and the left and right ends of the mounting box 3261 are symmetrically fixedly connected to pulleys 3263 that are slidably connected to the inner surfaces of adjacent slide grooves 324. The inner surface of the mounting box 3261 is rotatably connected to a cleaning brush 3264 that is closely attached to the front end of the filter screen 325. The left and right sides of the inner surface of the mounting box 3261 are slidably connected to V-shaped plates 3265 through the limit grooves opened. The left and right limit grooves on the front and rear of the V-plate 3265 are both arc-shaped tracks. The front and rear sides of the V-plate 3265 are inclined elastic metal sheets that are in close contact with the side walls of the mounting box 3261 in the initial state. A support plate 3267 is fixedly connected to the inner surface of the connecting groove 1 327. A number of support columns 3266 corresponding to the positions of the V-shaped plates 3265 are linearly distributed and fixedly connected to the upper end of the support plate 3267. A number of limit columns 3269 are rectangularly distributed and fixedly connected to the middle of the inner surface of the mounting box 3261.

[0046] Further, in order to realize the driving of the self-cleaning component 326, see Figure 4 The dustproof component 32 also includes a driving motor 321 installed at one end of the base 1. The output end of the driving motor 321 is fixedly connected to a winding shaft 322 that is rotatably connected to the inner surface of the base 1. The outer surface of the winding shaft 322 is symmetrically wound with a cable 323. The cable 323 is spirally wound on the outer surface of the winding shaft 322 and its two ends away from the winding shaft 322 are fixedly connected to the pulley 3263.

[0047] In summary, during the rotation of the driving motor 321, the cable 323 is driven to move via the winding shaft 322, and further, the pulley 3263 is pulled to slide in the slide groove 324, thereby driving the installation box 3261 to slide on the surface of the filter screen 325;

[0048] When the installation box 3261 slides on the surface of the filter 325, the cleaning brush 3264 will stick to the surface of the filter 325 and slide under the action of friction, thereby sweeping the dust on the surface of the filter 325 into the installation box 3261. Furthermore, the dust will remain in the installation box 3261 after entering the installation box 3261.

[0049] After the installation box 3261 moves downward and resets, the support column 3266 will push the V-shaped plate 3265 upward. At this time, the V-shaped plate 3265 slides upward on the inner surface of the installation box 3261, and under the limitation of the limiting column 3269, the elastic metal sheets on both sides of the V-shaped plate 3265 are bent. At this time, the installation box 3261 is connected to the connecting groove 327 at the bottom, and the dust therein will be discharged through the connecting groove 327.

[0050] Example 3. Based on Example 2, this example utilizes the action of the heat-conducting copper tube 332 and the micro-circulation pump 333 to drive the low-temperature coolant in the coolant storage tank 336 to circulate in the heat-conducting copper tube 332, and the action of the heat exchange plate 331 allows the inhaled air to exchange heat with the coolant, thereby reducing the temperature of the air. Simultaneously, the action of the heat exchange plate 331 and the staggered distribution of through holes 337 promote the precipitation of moisture in the air, so that the moisture condenses on the surface of the heat exchange plate 331 and flows to the sponge block 338 and is discharged through the action of the sponge block 338 and the drainage hole 339, thereby removing moisture in the inhaled air and reducing the corrosion of internal components by moisture.

[0051] Specifically, in order to separate the moisture in the inhaled air and prevent moisture from invading the interior of the equipment, causing corrosion and short circuit of electrical components, and affecting the stability and life of the equipment, refer to Figure 7 and Figure 8 The dehumidification component 33 includes a semiconductor refrigeration plate 334 fixedly connected to the upper end of the air outlet 36 and the top of the inner surface of the shell 31. The cold end of the semiconductor refrigeration plate 334 is fixedly connected to a coolant storage tank 336 filled with coolant. The hot end of the semiconductor refrigeration plate 334 is located inside the air outlet 36 and is fixedly connected to a plurality of heat dissipation fins 335. The lower end of the air outlet 36 is fixedly connected to a plurality of heat exchange plates 331 together with the inner wall of the shell 31. The front ends of the plurality of heat exchange plates 331 are provided with a plurality of through holes 337 communicating with the rear ends. The plurality of heat exchange plates 331 are linearly divided. The through holes 337 on two adjacent heat exchange plates 331 are distributed in a staggered manner, and the inner surfaces of several heat exchange plates 331 are fixedly connected with heat-conducting copper tubes 332. The output ends of several heat-conducting copper tubes 332 are connected with the coolant storage tank 336. The input ends of several heat-conducting copper tubes 332 are commonly provided with a micro-circulation pump 333 connected with the inner cavity of the coolant storage tank 336. The upper end of the base 1 is located at the lower side of the several heat exchange plates 331 and is fixedly connected with a sponge block 338. The lower end of the base 1 is provided with several drainage holes 339 connected with the cavity where the sponge block 338 is located.

[0052] The heat-conducting copper tube 332 inside the heat exchange plate 331 is filled with low-temperature coolant. The coolant exchanges heat with the heat exchange plate 331, causing the surface temperature of the heat exchange plate 331 to be lower than the ambient temperature. When the airflow hits the surface of the heat exchange plate 331, it exchanges heat with the heat exchange plate 331, thereby reducing the temperature of the incoming air.

[0053] Furthermore, after the temperature drops, the moisture in the air will precipitate and condense on the surface of the heat exchange plate 331, and then flow downward under the action of gravity, and finally flow into the sponge block 338 and be adsorbed by the sponge block 338. The air will continue to flow backward through the through hole 337, and then hit the next heat exchange plate 331, and perform the dehumidification operation again. The humidity in the air is reduced step by step through multiple heat exchange plates 331 to avoid affecting the diesel generator equipment 4 and its internal circuits.

[0054] It should be noted that the semiconductor refrigeration element 334 is a conventional semiconductor refrigeration element, which is a mature existing technology. Its cold end contacts the coolant through a diaphragm, continuously cooling the coolant. The heat dissipation fins 335 installed on its hot end are located inside the air outlet 36. When the air is exhausted outward, it will also take away the heat from the surface of the coolant storage tank 336, thereby ensuring the cooling efficiency of the heat dissipation fins 335.

[0055] The micro-circulation pump 333 is also a conventional circulation drive component in the prior art and is a mature technical equipment in the prior art. Its specific structure, operating principle, wiring and installation method will no longer be displayed and detailed in the present invention.

[0056] Example 4. Based on Example 3, this example further optimizes the air duct design and the heat dissipation structure design to improve the air flow efficiency and increase the heat dissipation area. The cold air is sent into the supply air duct 52 and the main air duct 51 by the distribution effect of the air uniforming plate 34 and the connecting port 35, and the cold air is sent into the shielding box 2 by the effect of the V-shaped guide pipe 521 and the L-shaped guide plate 514 to cool the diesel generator equipment 4 and drive the hot air inside the shielding box 2 to rise, and finally send it to the outlet 36 through the upper N-shaped guide pipe 531 and the return air duct 53 for discharge, thereby improving the air flow efficiency, increasing the heat dissipation area, and then improving the heat dissipation efficiency, enhancing the heat dissipation effect, ensuring the temperature stability of the equipment under high load, and avoiding performance degradation and safety hazards caused by overheating.

[0057] Specifically, to optimize the air duct design and heat dissipation structure design, improve air flow efficiency, and increase heat dissipation area, refer to Figure 9 The air duct structure 5 includes a main air duct 51 that is symmetrically distributed on the left and right and connected to the adjacent uniform air plate 34 and fixedly connected to the inner wall of the shielding box 2. The top wall of the inner cavity of the shielding box 2 is fixedly connected to a return air duct 53 that is connected to the air outlet 36. The rear end of the shell 31 is linearly distributed and fixedly connected to a number of supply air ducts 52 that are connected to the connecting port 35.

[0058] Further, to guide the hot air outflow, see Figure 10 The lower end of the return air duct 53 is linearly distributed and fixedly connected with several N-shaped guide tubes 531 that connect the return air duct 53 and the inner cavity of the shielding box 2. The front vertical part of the N-shaped guide tube 531 is connected to the supply air duct 52, and the rear vertical part of the N-shaped guide tube 531 is connected to the shielding box 2.

[0059] Further, to guide the hot air to float, see Figure 11The upper end of the air supply duct 52 is linearly distributed and fixedly connected with a number of V-shaped guide tubes 521 communicating with its inner cavity. The output direction of the V-shaped guide tubes 521 is inclined forward. The lower top wall of the inner cavity of the air supply duct 52 is linearly distributed and fixedly connected with a number of arc-shaped guide plates 522. The positions of the arc-shaped guide plates 522 correspond to those of the V-shaped guide tubes 521.

[0060] Furthermore, in order to increase the heat dissipation area, different positions of the diesel generator 4 can be exposed to low-temperature air, thereby improving the uniformity of heat dissipation, see Figure 12 The main air duct 51 includes an air uniform plate 2 511 fixedly connected to the inner wall of the shielding box 2 and fixedly connected to the rear end of the outer shell 31. The inner cavity of the air uniform plate 2 511 is linearly distributed with a plurality of connecting grooves 2 512 connected to the air uniform plate 1 34. The side of the air uniform plate 2 511 away from the shielding box 2 is fixedly connected with a fixing plate 513. The end of the fixing plate 513 away from the air uniform plate 2 511 is linearly distributed and fixedly connected with a plurality of L-shaped guide plates 514 connected to adjacent connecting grooves 2 512. The opening direction of the L-shaped guide plate 514 is inclined upward.

[0061] In summary, the air supply duct 52 is connected to the connecting port 35. The low-temperature air supplied to the air supply duct 52 by the connecting port 35 will be diverted by the arc-shaped guide plate 522 and enter the V-shaped guide pipe 521. The V-shaped guide pipe 521 will eject upward. The V-shaped guide pipe 521 is located below the diesel generator 4. The cold air ejected from the V-shaped guide pipe 521 will drive the hot air around the diesel generator 4 to float upward and exchange heat with the diesel generator 4, thereby assisting the main air ducts 51 on both sides to cool and dissipate heat from the diesel generator 4.

[0062] The second wind plate 511 is connected to the outer shell 31, and the connecting groove 2 512 inside it is connected to the first wind plate 34. The cold air distributed by the first wind plate 34 will be blown upward at an angle through the L-shaped guide plate 514, and dissipate heat from the surface of the diesel generator equipment 4. Further, through the cooperation of the air supply duct 52 set at the bottom, the air in the shielding box 2 forms an upward flow trend, thereby accelerating the rising of the hot air, and finally discharged through the N-shaped guide pipe 531, the return air duct 53 and the air outlet 36.
