Description

Technical Field

[0001] The present invention relates to the technical field of engineering machinery radiators, in particular to a dust and blockage prevention device for an engineering machinery radiator. Background Art

[0002] Construction machinery radiators are critical cooling devices that ensure the proper operation of core components. They promptly dissipate excess heat generated during equipment operation, preventing problems such as power loss and component damage caused by overheating. They are widely used in various types of construction machinery, including excavators, loaders, and cranes. For example, in the most common forced-air-cooled radiator, high-temperature coolant or hydraulic oil flows from the engine or hydraulic system into the metal tubes of the heat sink core. Heat is transferred through the tube walls to the external heat sink. At this point, the fan generates forced airflow, which rapidly flows over the surface of the heat sink, removing heat and lowering the temperature of the medium within the tube. The cooled medium then flows back to the engine or hydraulic system through the return port, repeating this cycle for continuous heat dissipation.

[0003] When construction machinery equipment is operating normally, heat is generated inside. It is difficult to dissipate the heat inside the equipment only with the help of natural ventilation and vents outside the equipment. At the same time, if the equipment is used for a long time, dust in the air will adhere to the filter net of the vent, resulting in poor ventilation effect. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A dust and blockage prevention device for a radiator of engineering machinery, comprising: A shell, a heat sink fixedly connected to a side of the shell, and a spray component fixedly connected to an inner side of the shell; a heat dissipation component, which is used to dissipate heat from the interior of the housing, wherein a side of the heat dissipation component is fixedly connected to a side of the housing away from the heat sink; The heat dissipation component includes a heat dissipation shell, a side surface of the heat dissipation shell is fixedly connected to the inner side of the shell, a fixing bracket is fixedly connected to the middle part of the inner side of the heat dissipation shell, a side of the fixing bracket close to the heat dissipation shell is fixedly connected to the motor, a side of the fixing bracket away from the motor is rotatably connected to a cleaning mechanism, an output end of the motor is fixedly connected to the cleaning mechanism, a side of the heat dissipation shell close to the fixing bracket is fixedly connected to a bracket, a side of the bracket close to the fixing bracket is rotatably connected to a fan blade, a side of the fan blade away from the bracket is fixedly connected to the cleaning mechanism, and fixing blocks are evenly arranged on the inner side of the heat dissipation shell, and the side surfaces of the fixing blocks are fixedly connected to the inner side of the heat dissipation shell; When the motor is turned on and rotated counterclockwise, the motor output drives the fan blades to rotate on the bracket through the connecting shaft, thereby dissipating heat and cooling the interior of the housing. At the same time, the rotation of the motor output also drives the cleaning mechanism to rotate synchronously inside the heat dissipation housing, achieving the goal of simultaneously dissipating heat and cooling the interior of the housing while completing the dust cleaning work inside the heat dissipation housing. The cleaning mechanism includes a connecting shaft, one end of the connecting shaft is fixedly connected to the output end of the motor, the side surface of the connecting shaft is rotatably connected to the inner side of the fixing frame, the other end of the connecting shaft is fixedly connected to the fan blade, both sides of the connecting shaft are fixedly connected to a connecting rod, the other end of the connecting rod is fixedly connected to a cleaning plate, a side of the cleaning plate close to the inner side of the heat dissipation housing is fixedly connected to a cleaning brush, a side of the cleaning brush away from the cleaning plate contacts the inner side of the heat dissipation housing, and a knocking assembly is slidably connected to the inner side of the cleaning plate; After the motor is turned on, the motor output drives the connecting shaft to rotate, and the connecting shaft then drives the cleaning plate to rotate inside the heat dissipation housing through the connecting rod. At this time, the cleaning brush on the cleaning plate will clean and sweep away the dust accumulated inside the heat dissipation housing. With the help of direct contact of the cleaning brush, the dust and particles attached to the surface are removed to prevent dust accumulation from affecting the heat dissipation efficiency. At the same time, as the cleaning plate rotates with the motor output end, the knocking assembly inside it slides under the action of centrifugal force. When the knocking assembly rotates with the connecting rod until it contacts the fixed blocks evenly distributed inside the heat dissipation shell, it will collide and generate vibration. The vibration impact can shake off the dust in the gaps that are difficult for the cleaning brush to reach, further enhancing the cleaning effect.

When the cleaning plate continues to rotate, the impact block will contact and collide with the fixed block, and the resulting vibration can shake off the dust attached to the surface of the heat dissipation housing, especially the dust accumulated in the gaps that are difficult to clean with the cleaning brush or the firmly adhered particles. The vibration impact makes up for the limitations of simple mechanical cleaning and improves the comprehensiveness of dust cleaning.

After the cylinder is squeezed, it drives the connecting rod to move inside the water pipe, and the connecting rod drives the baffle to separate from the inside of the water pipe and enter the water tank. At this time, the water stored in the water tank can smoothly enter the water pipe and flow out through the water hole on the water pipe.

[0005] The present invention provides a dust and blockage prevention device for a radiator of engineering machinery. It has the following beneficial effects: 1. The dust and anti-blocking device of the engineering machinery radiator is equipped with a cleaning mechanism. After the motor is turned on, the motor output end drives the connecting shaft to rotate, and the connecting shaft then drives the cleaning plate to rotate inside the heat dissipation shell through the connecting rod. At this time, the cleaning brush on the cleaning plate will clean and sweep away the dust accumulated on the inside of the heat dissipation shell. With the help of direct contact of the cleaning brush, the floating dust and particles attached to the surface are removed to prevent dust accumulation from affecting the heat dissipation efficiency.

[0006] 2. The dust and anti-blocking device of the engineering machinery radiator is provided with a knocking component. When the connecting rod drives the cleaning plate to rotate inside the heat dissipation shell along with the motor output end, the slide plate will slide smoothly along the sliding groove through the slider under the action of centrifugal force, thereby driving the impact block to move toward the fixed block inside the heat dissipation shell. When the cleaning plate continues to rotate, the impact block will contact and collide with the fixed block. The resulting vibration can shake off the dust attached to the surface of the heat dissipation shell, especially the dust accumulated in the gaps that are difficult to clean with the cleaning brush or the firmly adhered particles. The vibration impact makes up for the limitations of simple mechanical cleaning and improves the comprehensiveness of dust cleaning.

[0007] 3. The dust and anti-blocking device of the engineering machinery radiator is equipped with a spraying mechanism. When the connecting rod moves, it will drive the circular plate to slide synchronously on the inside of the water pipe. The circular plate pulls the second spring to deform. The setting of the second spring can not only drive the baffle to reset through elastic force when the water flow is closed to ensure the sealing of the water pipe, but also buffer the impact force of the connecting rod movement. The airflow generated by the rotation of the fan blades will blow the water flowing out of the water hole of the water pipe to the side of the heat sink in a directional manner. With the help of the airflow, the water flow is accelerated to diffuse, so that the cooling water evenly covers the surface of the heat sink, thereby improving the cooling efficiency and avoiding local overheating.

[0008] 4. The dust and anti-blocking device of the engineering machinery radiator is provided with a limit assembly. When the limit block is subjected to the extrusion force, it will drive the limit plate to move, and then the limit plate will move toward the inside of the limit shell through the limit shaft, and at the same time squeeze the third spring sleeved on the limit shaft. The elastic potential energy of the third spring is used to store the reset force to ensure that when the motor rotates counterclockwise and the fan blades dissipate heat for the inside of the heat dissipation shell, the water flow channel can be reliably blocked, avoiding the accidental spraying of water during the heat dissipation process, which not only ensures the independence of the heat dissipation work, but also prevents unnecessary moisture from entering and affecting the operation of the equipment, thereby improving the stability and reliability of the overall system.

[0011] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0012] See also Figure 1-Figure 3 The present invention provides a technical solution: a dust and blockage prevention device for a radiator of engineering machinery, comprising: The shell 1 has a heat sink 3 fixedly connected to the side of the shell 1 and a spray component 4 fixedly connected to the inner side of the shell 1; a heat dissipation component 2, which is used to dissipate heat from the interior of the housing 1, with a side of the heat dissipation component 2 fixedly connected to a side of the housing 1 away from the heat sink 3; See also Figure 1-Figure 5 The heat dissipation component 2 includes a heat dissipation shell 21, the side of the heat dissipation shell 21 is fixedly connected to the inner side of the shell 1, and a fixing frame 22 is fixedly connected to the middle part of the inner side of the heat dissipation shell 21. The fixing frame 22 is fixedly connected to the motor 23 on the side close to the heat dissipation shell 21, and the cleaning mechanism 26 is rotatably connected to the side of the fixing frame 22 away from the motor 23. The output end of the motor 23 is fixedly connected to the cleaning mechanism 26. The inner side of the heat dissipation shell 21 is fixedly connected to the bracket 24 on the side close to the fixing frame 22. The fan blade 25 is rotatably connected to the side of the bracket 24 close to the fixing frame 22. The cleaning mechanism 26 is fixedly connected to the side of the fan blade 25 away from the bracket 24. The inner side of the heat dissipation shell 21 is evenly provided with fixing blocks 27, and the side of the fixing block 27 is fixedly connected to the inner side of the heat dissipation shell 21; When the motor 23 is turned on and rotated counterclockwise, the output end of the motor 23 drives the fan blades 25 to rotate on the bracket 24 through the connecting shaft 261, thereby dissipating heat and cooling the interior of the housing 1; at the same time, the rotation of the output end of the motor 23 also drives the cleaning mechanism 26 to rotate synchronously inside the heat dissipation housing 21, thereby achieving the goal of dissipating heat and cooling the interior of the housing 1 while simultaneously completing the dust cleaning work inside the heat dissipation housing 21; See also Figures 1-6 The cleaning mechanism 26 includes a connecting shaft 261, one end of which is fixedly connected to the output end of the motor 23, the side of the connecting shaft 261 is rotatably connected to the inner side of the fixing frame 22, and the other end of the connecting shaft 261 is fixedly connected to the fan blade 25. Both sides of the connecting shaft 261 are fixedly connected to connecting rods 262, and the other end of the connecting rod 262 is fixedly connected to a cleaning plate 263. A cleaning brush 264 is fixedly connected to the side of the cleaning plate 263 close to the inner side of the heat dissipation housing 21, and a side of the cleaning brush 264 away from the cleaning plate 263 contacts the inner side of the heat dissipation housing 21. A knocking component 265 is slidably connected to the inner side of the cleaning plate 263. After the motor 23 is turned on, the output end of the motor 23 drives the connecting shaft 261 to rotate, and the connecting shaft 261 then drives the cleaning plate 263 to rotate inside the heat dissipation housing 21 through the connecting rod 262. At this time, the cleaning brush 264 on the cleaning plate 263 will clean and sweep away the dust accumulated inside the heat dissipation housing 21. With the help of the direct contact of the cleaning brush 264, the dust and particles attached to the surface are removed, thereby preventing the accumulation of dust from affecting the heat dissipation efficiency. The dust that is cleaned and dropped will be blown away and discharged in time by the airflow generated by the rotation of the fan blades 25, which reduces the probability of secondary deposition of dust and improves the thoroughness of cleaning; At the same time, when the cleaning plate 263 rotates with the output end of the motor 23, the knocking assembly 265 inside it slides under the action of centrifugal force. When the knocking assembly 265 rotates with the connecting rod 262 until it contacts the fixed blocks 27 evenly distributed inside the heat dissipation housing 21, it will collide and generate vibration. The vibration impact can shake off the dust in the gaps that are difficult for the cleaning brush 264 to reach, further enhancing the cleaning effect. See also Figure 1-Figure 7 The knocking assembly 265 includes a sliding groove 2651, which is opened on the side of the cleaning plate 263 away from the connecting rod 262. The slide plate 2652 is slidably connected to the inner side of the sliding groove 2651. The middle part of the slide plate 2652 is fixedly connected to the slider 2653. The side of the slider 2653 is slidably connected to the inner side of the sliding groove 2651. The side of the slider 2653 is fixedly connected to the brush 2654 on the side of the slide plate 2652 close to the slider 2653. The side of the slide plate 2652 away from the connecting rod 262 is fixedly connected to the impact block 2655. Both sides of the slide plate 2652 are fixedly connected to the sliding rod 2656. The other end of the sliding rod 2656 is slidably connected to the inner side of the cleaning plate 263. A first spring 2657 is sleeved on the sliding rod 2656. One end of the first spring 2657 is fixedly connected to the inner side of the cleaning plate 263, and the other end of the first spring 2657 is fixedly connected to the side of the slide plate 2652. When the connecting rod 262 drives the cleaning plate 263 to rotate inside the heat dissipation housing 21 along with the output end of the motor 23, under the action of centrifugal force, the slide plate 2652 will slide smoothly along the sliding groove 2651 through the slider 2653, thereby driving the impact block 2655 to move toward the fixed block 27 inside the heat dissipation housing 21. When the cleaning plate 263 continues to rotate, the impact block 2655 will contact and impact the fixed block 27. The resulting vibration can shake off dust attached to the surface of the heat dissipation housing 21, especially dust accumulated in gaps that are difficult to clean with the cleaning brush 264 or firmly adhered particles. The vibration impact compensates for the limitations of simple mechanical cleaning and improves the comprehensiveness of dust cleaning. At the same time, as the slide plate 2652 slides along the sliding groove 2651, the sliding rods 2656 on both sides thereof will synchronously pull the first spring 2657 to deform. When the contact and extrusion force between the impact block 2655 and the fixed block 27 is too large, the first spring 2657 will contract to cushion the impact force, thereby preventing wear or deformation of the impact block 2655 and the fixed block 27 due to rigid collision, thereby extending the service life of the components and ensuring long-term stable operation. See also Figures 1-9The present invention provides a technical solution: the spray component 4 includes a water tank 41, the side of the water tank 41 is fixedly connected to the inner side of the shell 1, the middle of the water tank 41 is fixedly connected to the spray mechanism 42, the middle of the side of the spray mechanism 42 is fixedly connected to the mounting shell 44, the side of the mounting shell 44 away from the spray mechanism 42 is rotatably connected to a rotating plate 47, the middle of the rotating plate 47 is fixedly connected to a rotating shaft 43, the end of the rotating plate 47 away from the rotating shaft 43 is fixedly connected to a rotating block 45, both sides of the rotating block 45 are fixedly connected to a clamping block 46, the other end of the rotating shaft 43 is fixedly connected to the middle of the fan blade 25, and the side of the rotating block 45 away from the rotating plate 47 is rotatably connected to the inner side of the mounting shell 44; When the heat sink 3 needs to be sprayed and cooled, the motor 23 is turned on and rotated clockwise. The output end of the motor 23 drives the fan blades 25 to rotate on the bracket 24 through the connecting shaft 261. At this time, the fan blades 25 drive the rotating plate 47 to rotate in the middle of the mounting housing 44 through the rotating shaft 43, thereby causing the water in the water tank 41 to flow out through the spraying mechanism 42. At the same time, the airflow generated by the rotation of the fan blades 25 guides the water flow and sprays it onto the heat sink 3, thereby achieving spray cooling of the heat sink 3. See also Figures 1-11 The spraying mechanism 42 includes a water pipe 421, the middle part of the water pipe 421 is fixedly connected to the side of the mounting shell 44, the side of the water pipe 421 is fixedly connected to the inner side of the water tank 41, and circular plates 424 are slidably connected on both sides of the inner cavity of the water pipe 421. The side of the circular plate 424 is slidably connected to the inner side of the water pipe 421, and the middle part of the circular plate 424 is fixedly connected to a connecting rod 422. A second spring 426 is sleeved on the connecting rod 422, one end of the second spring 426 is fixedly connected to the side of the circular plate 424, and the other end of the second spring 426 is fixedly connected to the side of the mounting shell 44. One end of the connecting rod 422 is fixedly connected to a baffle 423, and the other end of the connecting rod 422 is fixedly connected to a cylinder 427. The middle part of the inner side of the mounting shell 44 is rotatably connected to the limiting component 425, and the side of the connecting rod 422 is slidably connected to the inner side of the mounting shell 44; When the output end of the motor 23 drives the connecting shaft 261 to rotate clockwise, the connecting shaft 261 will synchronously drive the fan blades 25 to rotate on the bracket 24. As the fan blades 25 rotate, the rotating plate 47 is driven to rotate on the mounting housing 44 via the rotating shaft 43. The rotating shaft 43 also drives the rotating block 45 to rotate synchronously with the clamping blocks 46 on both sides of the rotating block 45 inside the mounting housing 44. When the block 46 rotates, it drives the limiting assembly 425 to move synchronously inside the mounting housing 44, thereby squeezing the cylinder 427. After the cylinder 427 is squeezed, it drives the connecting rod 422 to move inside the water pipe 421. The connecting rod 422 then drives the baffle 423 to separate from the inside of the water pipe 421 and enter the water tank 41. At this time, the water stored in the water tank 41 can smoothly enter the water pipe 421 and flow out through the water hole on the water pipe 421. At the same time, when the connecting rod 422 moves, it drives the circular plate 424 to slide synchronously on the inside of the water pipe 421. The circular plate 424 pulls the second spring 426 to deform. The setting of the second spring 426 can not only drive the baffle 423 to reset by elastic force when the water flow is closed, ensuring the sealing of the water pipe 421, but also buffer the impact force of the movement of the connecting rod 422. The airflow generated by the rotation of the fan blades 25 will blow the water flowing out of the water hole of the water pipe 421 toward the side of the heat sink 3. With the help of the airflow, the water flow is accelerated to spread, so that the cooling water evenly covers the surface of the heat sink 3, thereby improving the cooling efficiency and avoiding local overheating. See also Figures 1-12 The limiting assembly 425 includes a limiting shell 4251, a side of the card block 46 away from the rotating block 45 contacts the inner side of the limiting shell 4251, and the side of the limiting shell 4251 is rotatably connected to the inner side of the mounting shell 44, and both sides of the limiting shell 4251 are fixedly connected to the extrusion block 4252, and both sides of the inner cavity of the limiting shell 4251 are rotatably connected to the limiting plate 4253, one side of the limiting plate 4253 is fixedly connected to the limiting block 4254, and the side of the limiting plate 4253 close to the inner wall of the limiting shell 4251 is fixedly connected to the limiting shaft 4255, and the other end of the limiting shaft 4255 is slidably connected to the inner side of the limiting shell 4251, and a third spring 4256 is sleeved on the limiting shaft 4255, one end of the third spring 4256 is fixedly connected to the inner side of the limiting shell 4251, and the other end of the third spring 4256 is fixedly connected to the side of the limiting plate 4253; When the output end of the motor 23 drives the connecting shaft 261 to rotate clockwise, the connecting shaft 261 drives the fan blades 25 to rotate synchronously on the bracket 24. While the fan blades 25 rotate, the rotating plate 47 is driven to rotate on the mounting housing 44 through the rotating shaft 43. At the same time, the rotating shaft 43 also drives the rotating block 45 and the clamping blocks 46 on both sides to rotate inside the mounting housing 44. When the clamping block 46 contacts the direct surface of the limit block 4254 and is squeezed, the clamping block 46 pushes the limit block 4254 to move inside the fixed housing 1, thereby causing the squeezing blocks 4252 on both sides of the limit housing 4251 to contact and squeeze the cylinder 427, ultimately allowing the water in the water tank 41 to flow smoothly into the water pipe 421. When the output end of the motor 23 drives the connecting shaft 261 to rotate counterclockwise, the connecting shaft 261 drives the fan blades 25 to rotate on the bracket 24. At the same time, the fan blades 25 drive the rotating plate 47 to rotate on the mounting housing 44 through the rotating shaft 43. At the same time, the rotating shaft 43 also drives the rotating block 45 and the clamping blocks 46 on both sides to rotate synchronously inside the mounting housing 44, so that the clamping blocks 46 on both sides contact and squeeze the inclined surfaces of the limit blocks 4254. When the limiting block 4254 is subjected to the extrusion force, it drives the limiting plate 4253 to move, thereby causing the limiting plate 4253 to move toward the inside of the limiting housing 4251 through the limiting shaft 4255, and at the same time, compressing the third spring 4256 mounted on the limiting shaft 4255. The elastic potential energy of the third spring 4256 is used to store a restoring force, ensuring that the water flow channel can be reliably blocked when the motor 23 rotates counterclockwise and the fan blades 25 dissipate heat from the inside of the heat dissipation housing 21. It avoids the accidental spraying of water during the heat dissipation process, which not only ensures the independence of the heat dissipation work, but also prevents unnecessary moisture from entering and affecting the operation of the equipment, thereby improving the stability and reliability of the overall system.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
