Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation of generator sets, and particularly to a heat dissipation device for generator sets. Background Art

[0002] During the operation of a generator set, a large amount of heat will be generated. If the heat cannot be dissipated in time, the long-term high-temperature state will damage the equipment and even cause safety accidents such as fires. In the existing heat dissipation system, an air inlet is usually provided on the box body and an exhaust fan is installed to ventilate and dissipate heat inside the generator set. However, the air-cooled system is prone to dust accumulation at the grille, and the long-term dust accumulation will lead to poor heat dissipation.

[0003] In view of the above problems, those skilled in the art have improved the existing technology. For example, an integrated gas generator set ventilation and heat dissipation air intake device with the publication number of CN221462413U includes a main body. A generator set is fixedly installed inside the main body. A heat dissipation port is opened on the front surface of the main body. Ventilation ports are opened on the outer walls at both ends of the main body. A heat dissipation device capable of dissipating heat from the generator set is provided inside the main body. A cleaning device capable of cleaning the ventilation ports is provided on the outer wall of the main body. A motor one is fixedly installed inside the main body, and a motor two is fixedly installed on the outer wall of the main body. Starting the motor one drives the rotating rod to rotate, thereby driving the driven wheel to rotate, causing the fan blades to rotate and driving the air inside the main body to circulate to dissipate heat from the generator set. Starting the motor two makes the moving frame move up and down, thereby cleaning the ventilation ports. However, the above device cleans the grille through a brush, and the dust will be raised when the brush moves, resulting in poor cleaning effect and not meeting the use requirements, and it is still inconvenient to use.

Detailed implementation manner

[0020] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] See Figures 1 to 5 , the present invention provides a heat dissipation device for a generator set, including a housing 1 and a cleaning assembly 2. The bottom end of the housing 1 is detachably connected with a chassis 11. A plurality of exhaust holes 13 are provided on the top surface of the housing 1. Rotatable fan blades (not shown in the figure) are provided in each of the exhaust holes 13. The exhaust holes 13 are connected to the generator set through a pipeline, and can perform air cooling on the generator set. Grilles 14 are detachably connected to the side walls at both ends of the housing 1. Dense holes (not shown in the figure) are provided on the grilles 14, which can not only allow air to pass through, but also play a certain role in blocking dust in the air.

[0022] See Figures 1 to 5, the cleaning assembly 2 includes a driving shaft 21 and a liquid chamber 23. The driving shaft 21 is rotatably arranged at the inner top of the housing 1. The driving shaft 21 is located in the middle of the housing 1. One end of the driving shaft 21 is rotatably connected to the side wall of the housing 1, and the other end of the driving shaft 21 is connected to the output shaft of a driving member (not shown in the figure). The driving member is arranged on the side wall of the housing 1 and can drive the driving shaft 21 to rotate reciprocally. A positive rotating shaft sleeve 22 is rotatably sleeved in the middle of the driving shaft 21. A first ratchet wheel is arranged on the side wall of one end of the positive rotating shaft sleeve 22. The first ratchet wheel, the positive rotating shaft sleeve 22 and the driving shaft 21 are concentric. A first pawl that can rotate unidirectionally is rotatably arranged on the driving shaft 21. When the driving shaft 21 rotates forward, the first ratchet wheel cooperates with the first pawl to make the positive rotating shaft sleeve 22 rotate forward synchronously with the driving shaft 21. Inside the housing 1 below the positive rotating shaft sleeve 22, there is a liquid chamber 23. The bottom of the liquid chamber 23 is connected with a liquid inlet pipe and a liquid outlet pipe. Both the liquid inlet pipe and the liquid outlet pipe are communicated with the liquid cooling circuit. One-way valves are arranged in both the liquid inlet pipe and the liquid outlet pipe, and the directions of the two one-way valves are opposite. A piston plate 231 is slidably arranged in the liquid chamber 23. When the piston plate 231 rises, the coolant in the liquid cooling circuit enters the liquid chamber 23 through the liquid inlet pipe. When the piston plate 231 descends, the coolant in the liquid chamber 23 enters the liquid cooling circuit through the liquid outlet pipe. Two central sliders 222 are arranged on the positive rotating shaft sleeve 22. Two first circulating grooves with opposite directions are arranged on the surface of the positive rotating shaft sleeve 22 (the first circulating groove is an arc groove that surrounds the positive rotating shaft sleeve 22 for one week and is connected end to end, and it can make the central slider 222 move reciprocally without changing the rotating direction of the positive rotating shaft sleeve 22). The central sliders 222 are in one-to-one correspondence and cooperation with the first circulating grooves (that is, through holes for the positive rotating shaft sleeve 22 to pass through are arranged on the central sliders 222, and guide posts that cooperate with the first circulating grooves are arranged on the inner side walls of the through holes). Cross bar groups 232 are rotatably arranged between the central sliders 222 and the piston plate 231 (that is, the two ends of the top of the cross bar group 232 are respectively rotatably connected to the two central sliders 222, and the two ends of the bottom of the cross bar group 232 are rotatably connected with plate members, and the plate members are all slidably connected to the piston plate 231).

[0023] See Figures 1 to 5, anti-rotation shaft sleeves 24 are rotatably sleeved on the driving shaft 21 at both sides of the positive rotation shaft sleeve 22. Second ratchets (the directions of the second ratchets are opposite to those of the first ratchets) are arranged on the side walls at one ends of the anti-rotation shaft sleeves 24. The second ratchets, the anti-rotation shaft sleeves 24 and the driving shaft 21 are concentric. A second ratchet pawl capable of one-way rotation is rotatably arranged on the driving shaft 21. When the driving shaft 21 rotates reversely, the second ratchet is engaged with the second ratchet pawl, so that the anti-rotation shaft sleeve 24 follows the driving shaft 21 to rotate reversely synchronously. Side sliders 241 are arranged on the anti-rotation shaft sleeves 24. Second circulation grooves (the structures thereof refer to the first circulation grooves) are arranged on the anti-rotation shaft sleeves 24. The side sliders 241 are in one-to-one correspondence and cooperation with the second circulation grooves (the cooperation mode thereof refers to that of the central slider 222 and the first circulation groove). Pushing seats 25 are slidably arranged on the tops of the shells 1 at both sides of the driving shaft 21. Both ends of the pushing seats 25 are slidably connected to the side walls of the shells 1. Link rods 242 are rotatably arranged between the pushing seats 25 and the side sliders 241 (that is, one end of the link rod 242 is rotatably connected to the pushing seat 25, and the other end of the link rod 242 is rotatably connected to the side slider 241). Transmission gears 252 are rotatably arranged on one sides of the pushing seats 25 far away from the driving shaft 21. The transmission gears 252 are arranged on connecting shafts 253. Both ends of the connecting shafts 253 are rotatably connected to the first support plates. The first support plates are fixedly connected to the pushing seats 25. Second support plates are connected to the side walls on one sides of the pushing seats 25 close to the driving shaft 21. Driven gears 251 are rotatably connected to the ends of the second support plates through positioning shafts. The distance between the driven gear 251 and the pushing seat 25 cooperating with it is greater than the distance between the driving shaft 21 and the pushing seat 25. The two second support plates are arranged in a staggered manner. Driving gears 221 capable of meshing with the driven gears 251 are arranged at both ends of the positive rotation shaft sleeve 22. When the pushing seat 25 is located at one end of its movement range far away from the driving shaft 21, the driven gear 251 is meshed with the driving gear 221. A first belt is arranged between the positioning shaft and the connecting shaft 253 which cooperate with each other, so that the driven gear 251 can drive the transmission gear 252 to rotate.

[0024] See Figures 1 to 5, rotating shafts 28 are provided at the tops of both ends of the housing 1. Both ends of the rotating shaft 28 are rotatably connected to the side wall of the housing 1. A central gear 282 is provided on the rotating shaft 28. When the pushing seat 25 is located at one end of its movement range away from the driving shaft 21, the transmission gear 252 meshes with the central gear 282. Sliding seats 29 are slidably provided on the housing 1 at the ends of the rotating shaft 28. The sliding seats 29 are all located on the side of the rotating shaft 28 close to the driving shaft 21. Connecting ropes 292 are connected to the bottom ends of the sliding seats 29. The connecting ropes 292 extend downward to the bottom of the housing 1. Fixed shafts cooperating with the connecting ropes 292 are provided on the side walls at the bottom of the housing 1. After the connecting ropes 292 cooperate with the fixed shafts, they extend upward and wind around the rotating shaft 28. When the transmission gear 252 drives the central gear 282 and the rotating shaft 28 to rotate, the sliding seat 29 can be driven to move downward. Fixed blocks 293 are provided on the side walls of the housing 1 above the sliding seat 29. Springs are provided between adjacent fixed blocks 293 and the sliding seat 29. When the spring is in the natural state, the sliding seat 29 is located at the top of the housing 1.

[0025] See Figures 1 to 5 , a bearing rod 26 is provided in the housing 1 on the side of the sliding seat 29 close to the driving shaft 21. The bottom end of the bearing rod 26 is rotatably connected to the side wall of the housing 1 through a smooth shaft. First torsion springs are provided at the connections between the smooth shaft and the side wall of the housing 1. When the first torsion springs are in the natural state, the bearing rods 26 are all in the vertical state. Extension rods are provided through the top ends of the bearing rods 26. The top ends of the extension rods are rotatably connected to the top seats 261. The top seats 261 are all slidably connected to the side wall at the top of the housing 1. The pushing seat 25 can push the top seat 261 to move horizontally, thereby driving the bearing rod 26 to rotate. A lifting seat 27 is slidably provided on the bearing rod 26. An arc-shaped strip 291 (the arc-shaped strip 291 does not interfere with the bearing rod 26) passing through the lifting seat 27 is provided on the sliding seat 29, so that the lifting seat 27 can not only rotate synchronously with the bearing rod 26, but also lift synchronously with the sliding seat 29. A main roller shaft 271 is rotatably provided between the two lifting seats 27 at the same end of the housing 1. The main roller shaft 271 is used to carry the cleaning sticky sheet roller shaft (that is, the untreated cleaning sticky sheet is wound around the cleaning sticky sheet roller shaft, and the main roller shaft 271 can drive the cleaning sticky sheet roller shaft to rotate synchronously). Lifting gears 272 are provided at both ends of the main roller shaft 271. Rack teeth capable of meshing with the lifting gears 272 are provided on the side walls at the ends of the housing 1. When the transmission gear 252 meshes with the central gear 282, the sliding seat 29 can drive the lifting seat 27 to descend. At this time, the lifting gear 272 meshes with the rack teeth, and the main roller shaft 271 rotates while descending, so that the cleaning sticky sheet (the cleaning sticky sheet is a sheet-like object with a certain stickiness, and its function refers to the sticky hair cylinder) adheres to the grille 14.

[0026] See Figures 1 to 5, a sub-roller shaft 263 is rotatably provided on each top seat 261. The two ends of the sub-roller shaft 263 are respectively rotatably connected to the side walls of the top seat 261. The sub-roller shaft 263 is used to carry a waste roller shaft (the waste roller shaft is used to carry a used cleaning sticky sheet, and the cleaning sticky sheet is connected to the waste roller shaft). The sub-roller shaft 263 can drive the waste roller shaft to rotate. Rotating shaft sleeves 264 are rotatably sleeved on both ends of the sub-roller shaft 263. Third ratchets are provided on the side walls of one end of each rotating shaft sleeve 264. The third ratchet, the rotating shaft sleeve 264 and the sub-roller shaft 263 are concentric. Third pawls that can rotate in one direction are rotatably provided on the sub-roller shaft 263. When the third ratchet cooperates with the third pawl, the rotating shaft sleeve 264 can drive the sub-roller shaft 263 to rotate. End shafts are rotatably provided on the side walls at both ends of the top seat 261. Moving gears 262 are provided on the end shafts. Second torsion springs are provided at the connections between the end shafts and the top seat 261. Second belts are provided between adjacent end shafts and rotating shaft sleeves 264. End gears 281 that can mesh with the moving gears 262 are provided at both ends of the rotating shaft 28. When the transmission gear 252 meshes with the central gear 282, the moving gear 262 meshes with the end gear 281.

[0027] See Figures 1 to 5 , preferably, the grilles 14 are all inclined, and the distance between the bottom end of the grille 14 and the center of the housing 1 is greater than the distance between the top end of the grille 14 and the center of the housing 1, which can facilitate the separation of the cleaning sticky sheet from the grille 14.

[0028] See Figures 1 to 5 , preferably, dense sticky hairs can be provided on the cleaning sticky sheet, which can remove the dust inside the holes on the grille 14.

[0029] See Figures 1 to 5 , preferably, a limiting shaft passing through the central slider 222 and the side slider 241 is provided below the driving shaft 21. Both ends of the limiting shaft are connected to the side wall of the housing 1, and the limiting shaft can prevent the central slider 222 and the side slider 241 from rotating on their own.

[0030] See Figures 1 to 5 , preferably, a plurality of side brackets 12 are detachably connected to the top surface of the chassis 11, and the side brackets 12 can provide stable support for the housing 1.

[0031] See Figures 1 to 5 , preferably, a detachable top cover is provided at the top of the housing 1, which is convenient for the user to replace the cleaning sticky sheet.

[0032] See Figures 1 to 5 , preferably, the user can set an auxiliary plate elastically connected to the top seat 261 on the top seat 261. The pushing seat 25 cooperates with the auxiliary plate, and relative movement can occur between the auxiliary plate and the top seat 261, providing a certain movement margin for the pushing seat 25, so as to ensure that when the overall diameter of the cleaning sticky sheet roller changes, the cleaning sticky sheet can still adhere to the grille 14.

[0033] See Figures 1 to 5 , preferably, the driving member is a rotary motor, which can provide sufficient power.

[0034] During the implementation of the present invention: when the device is in the initial state, the pushing seat 25 is located at one end close to the driving shaft 21 within its movement range, and the driving member rotates forward. At this time, the first ratchet wheel cooperates with the first ratchet pawl, and the second ratchet wheel does not cooperate with the second ratchet pawl. The forward rotating shaft sleeve 22 rotates, and the reverse rotating shaft sleeve 24 does not rotate. The two central sliders 222 reciprocate synchronously (the movement directions of the two central sliders 222 are opposite), driving the piston plate 231 to reciprocate up and down, realizing the circulation of the coolant. When it is necessary to clean the inner wall of the grille 14, the driving member rotates reversely. At this time, the first ratchet wheel does not cooperate with the first ratchet pawl, and the second ratchet wheel cooperates with the second ratchet pawl. The forward rotating shaft sleeve 22 does not rotate, and the reverse rotating shaft sleeve 24 rotates. The two side sliders 241 approach each other, causing the pushing seat 25 to move away from the driving shaft 21 in the direction, and the pushing seat 25 drives the top seat 261 to move, so that the bearing rod 26 rotates to be parallel to the grille 14. When the pushing seat 25 is located at the end far from the driving shaft 21 within its movement range, the driven gear 251 meshes with the driving gear 221, the transmission gear 252 meshes with the central gear 282, the moving gear 262 meshes with the end gear 281, the lifting gear 272 meshes with the rack, and the cleaning sticky sheet roller shaft abuts against the grille 14. Then the driving member rotates forward, and the forward rotating shaft sleeve 22 drives the driving gear 221 to rotate, so that the rotating shaft 28 rotates. Under the action of the connecting rope 292, the lifting seat 27 is driven to descend. Under the meshing action of the rack and the lifting gear 272, the main roller shaft 271 rotates while descending, so that the cleaning sticky sheet adheres to the grille 14. During this process, the end gear 281 drives the moving gear 262 to rotate, the second torsion spring deforms, the third ratchet wheel does not cooperate with the third ratchet pawl, and the rotating shaft sleeve 264 cannot drive the auxiliary roller shaft 263 to rotate. When the main roller shaft 271 reaches below the grille 14, the driving member rotates reversely, driving the pushing seat 25 to reset. Under the action of the first torsion spring, the bearing rod 26 returns to the vertical state, so that the cleaning sticky sheet is disengaged from the grille 14 (adjusting the viscosity of the cleaning sticky sheet so that it can be smoothly disengaged from the grille 14. At this time, the dust adheres to the cleaning sticky sheet). Under the action of the spring, the sliding seat 29 drives the lifting seat 27 to rise and reset. During this process, the lifting gear 272 does not mesh with the rack, and the main roller shaft 271 only rises and does not rotate. And because the second torsion spring restores deformation, driving the end shaft to rotate, the third ratchet wheel cooperates with the third ratchet pawl, causing the auxiliary roller shaft 263 to rotate, and the used cleaning sticky sheet is wound around the waste roller shaft.

[0035] The present invention provides a heat dissipation device for a generator set, and its beneficial effects are as follows: 1. It can dissipate heat from the generator set through a combination of air cooling and liquid cooling to ensure good heat dissipation effect. It can also automatically clean the grille more thoroughly, extend the continuous operation time of the device, ensure good heat dissipation efficiency, and reduce the labor intensity of users.

[0036] 2. In the present invention, the coolant circulation and the cleaning of the grille can be completed with only one driving part, which reduces the manufacturing cost and saves the usage cost during long-term operation, meeting the enterprise's need to reduce costs and increase efficiency.

[0037] In summary, the beneficial effects of the present invention are as follows: It can dissipate heat through a combination of air cooling and liquid cooling to ensure good heat dissipation effect, can automatically clean the grille, extend the continuous operation time of the device, reduce the labor intensity of users, and can also avoid dust emission to ensure good cleaning effect.

[0038] Certainly, the present invention can also have various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make corresponding changes and deformations according to the present invention, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present invention.
