Description

A waterproof fan housing for excavators Technical Field

[0001] This utility model relates to the technical field of waterproof fan housings, and in particular to a waterproof fan housing for excavators. Background Technology

[0002] In modern engineering construction, excavators, as an important type of construction machinery, often need to operate in various complex and harsh environments, among which rainy weather operations are extremely common. The fan casing of the excavator is crucial for maintaining internal heat dissipation and ventilation, and its performance directly affects the stable operation and service life of the excavator.

[0003] Traditional excavator blower housings have several shortcomings in waterproofing design. On the one hand, ordinary ventilation structures are insufficient to effectively prevent rainwater intrusion. When rainwater enters the blower housing through the vents, it can easily cause short circuits and corrosion of internal electronic components, severely affecting the normal operation of the blower. This can lead to the failure of the excavator's cooling system, causing overheating and other problems. On the other hand, even if existing blower housings have some simple waterproofing measures, such as a single rain shield, they cannot effectively prevent rainwater from accumulating on the surface of waterproof components in the face of continuous rainfall and complex and changing operating environments. Long-term accumulation will still increase the risk of rainwater seepage. Moreover, existing blower housings are not perfect in their coordination of waterproofing and heat dissipation functions. They often sacrifice heat dissipation performance in pursuit of waterproofing, or prioritize heat dissipation while significantly reducing waterproofing performance. Therefore, there is an urgent practical need to develop a waterproof blower housing for excavators that can both effectively waterproof and ensure good heat dissipation. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a waterproof fan housing for excavators.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof fan housing for an excavator, comprising an assembly housing, a cooling fan installed inside the assembly housing, a ventilation pipe fixedly connected to one side of the assembly housing, a cooling housing fixedly connected to one side of the ventilation pipe, a ventilation grille fixedly connected to the surface of the cooling housing, a rotating rail fixedly connected to the surface of the cooling housing, a turntable slidably connected to the inner wall of the rotating rail, and an arc-shaped water guide plate fixedly connected to the side of the turntable near the ventilation grille.

[0006] As a preferred embodiment of the waterproof fan housing for excavators described in this utility model, a partition is fixedly connected to the inner wall of the ventilation pipe, and a ventilation ring plate is fixedly connected to one side of the partition. The surface of the ventilation ring plate is evenly provided with multiple ventilation slots.

[0007] As a preferred embodiment of the waterproof fan housing for excavators described in this utility model, the number of the rotating rails is set to four sets, and the array is distributed on the inner wall side surface of the heat dissipation housing.

[0008] In a preferred embodiment of the waterproof fan housing for excavators described in this utility model, a drive fan head is provided on the inner side of the ventilation ring plate, and one end of the drive fan head is fixedly connected to the surface of the turntable.

[0009] In a preferred embodiment of the waterproof fan housing for excavators described in this utility model, the number of arc-shaped water guide plates is set to multiple sets, and they are evenly and staggeredly arranged on the surface of the turntable.

[0010] As a preferred embodiment of the waterproof fan housing for excavators described in this utility model, a drainage groove is provided on the lower surface of the inner wall of the heat dissipation housing, and a baffle plate is provided on one side of the drainage groove, with the side wall of the baffle plate being fixedly connected to the inner wall of the heat dissipation housing.

[0011] This utility model provides a waterproof fan housing for excavators. It has the following advantages:

[0012] By turning on the cooling fan, the airflow generated by the cooling fan is precisely guided through the baffle and the ventilation ring plate to the drive fan head inside the ventilation ring plate. The drive fan head is driven to rotate by the airflow, which drives the turntable to rotate under the support of the rotating rail, causing the rainwater accumulated on the surface of the water guide plate to slide off. The staggered water guide plates not only prevent rainwater from entering the casing, but also discharge the airflow generated by the cooling fan, thus achieving waterproofing and rainproofing. The falling rainwater flows out of the cooling casing through the drainage slots, and the baffle plate further prevents rainwater from flowing in from the drainage slots, enhancing the waterproof performance of the equipment.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Referring to Figures 1 to 8, this utility model provides a technical solution: a waterproof fan housing for an excavator, including an assembly housing 1, a cooling fan 4 installed inside the assembly housing 1, a ventilation pipe 2 fixedly connected to one side of the assembly housing 1, a cooling housing 3 fixedly connected to one side of the ventilation pipe 2, a ventilation grille 13 fixedly connected to the surface of the cooling housing 3, and a rotating rail 7 fixedly connected to the surface of the cooling housing 3. A turntable 8 is slidably connected to the inner wall of the rotating rail 7, and an arc-shaped water guide plate 10 is fixedly connected to the side of the turntable 8 near the ventilation grille 13. When operating in rainy weather, the water guide plate on one side of the ventilation grille 13 can block rainwater and prevent rainwater from falling into the housing. When the turntable 8 rotates on the inner wall of the rotating rail 7, it can drive the water guide plate to rotate, thereby preventing rainwater from accumulating on the surface of the water guide plate and improving the waterproof effect.

[0025] Referring to Figures 4, 5, and 6, in this embodiment: a partition 5 is fixedly connected to the inner wall of the ventilation pipe 2, and a ventilation ring plate 6 is fixedly connected to one side of the partition 5. Multiple ventilation slots are evenly opened on the surface of the ventilation ring plate 6. The number of rotating rails 7 is set to four sets, and they are arrayed on the inner wall side surface of the heat sink housing 3. Through the partition 5 and the ventilation ring plate 6, the airflow discharged by the heat sink fan 4 can be guided to the drive fan head 9, so that the drive fan head 9 can drive the turntable 8 to rotate, avoiding rainwater accumulation on the surface of the water guide plate. At the same time, the four sets of rotating rails 7 can support the turntable 8 during rotation, improving the stability of the turntable 8 during rotation.

[0026] Referring to Figures 4, 7, and 8, specifically, a drive fan head 9 is provided on the inner side of the ventilation ring plate 6. One end of the drive fan head is fixedly connected to the surface of the turntable 8. The number of arc-shaped water guide plates 10 is set in multiple groups and is evenly staggered on the surface of the turntable 8. A drainage groove hole 12 is opened on the lower surface of the inner wall of the heat dissipation housing 3. A baffle plate 11 is provided on one side of the drainage groove hole 12. The side wall of the baffle plate 11 is fixedly connected to the inner wall of the heat dissipation housing 3. Through the staggered arrangement of the water guide plates, rainwater can be prevented from entering the housing, while the airflow generated by the heat dissipation fan 4 can be discharged, thereby achieving the effect of waterproofing and rainproofing. When rainwater falls from the water guide plate, it can flow out of the heat dissipation housing 3 through the drainage groove hole 12. At the same time, the baffle plate 11 can further block rainwater and prevent it from flowing into the housing from the side of the drainage groove hole 12, thus enhancing the waterproof performance of the equipment.

[0027] Working principle: When the excavator is operating in rainy weather, the cooling fan 4 inside the housing 1 starts, and the airflow generated is precisely guided to the drive fan head 9 inside the ventilation ring plate 6 through the baffle 5 and the ventilation ring plate 6. The drive fan head 9 rotates under the push of the airflow. When the drive fan head 9 rotates, it will drive the turntable 8 to rotate under the support of the turntable 7, causing the rainwater accumulated on the surface of the water guide plate to slide off. At the same time, the staggered arrangement of the water guide plates can prevent rainwater from entering the housing, and at the same time, it can exhaust the airflow generated by the cooling fan 4, thereby achieving the effect of waterproofing and rainproofing. When the rainwater falls from the water guide plate, it can flow out of the cooling housing 3 through the drainage slot 12. At the same time, the setting of the baffle plate 11 can further block the rainwater and prevent it from flowing into the housing from the drainage slot 12 side, thus enhancing the waterproof performance of the equipment.
