Description

Technical Field

[0001] The utility model relates to the technical field of controllers, in particular to a high-protection outdoor controller dedicated to cranes. Background Art

[0002] With the widespread use of cranes in construction, ports, industrial manufacturing, and other fields, their operating environments are becoming increasingly complex and diverse. In outdoor scenarios, cranes are constantly exposed to harsh weather conditions such as high and low temperatures, strong winds, heavy rain, and sandstorms. They also face the challenges of high humidity, corrosive gases, and complex geographical environments. Traditional controller designs generally lack adaptability to extreme outdoor environments and have insufficient protection. This allows moisture and dust to easily intrude into internal electronic components, causing equipment failures and seriously threatening the safety and stability of the cranes.

[0003] Existing crane controllers often use conventional sealed structures, making it difficult to balance protection and heat dissipation requirements. Furthermore, seal weaknesses exist in key locations, such as connectors and heat sinks. Over long-term operation, environmental corrosion can cause internal system problems, such as short circuits and component aging. This increases both failure rates and maintenance costs. In dusty and humid environments, such as construction sites and ports, the inadequate protection levels of conventional controllers have become a technical bottleneck restricting efficient crane operation. Therefore, we propose a highly protected outdoor controller specifically for cranes. Utility Model Content

Screws are arranged inside the connecting holes. The lower ends of the screws are threadedly connected to the inside of the connecting blind holes. The upper cover is connected to the box body by setting screws, and the gap between the upper cover and the box body is sealed by setting glue dots.

[0008] Furthermore, the sealing assembly includes a connecting groove, a first rubber sealing frame and a spring. A connecting groove is provided on the upper side of the box body, and the first rubber sealing frame is slidably connected to the inside of the connecting groove. Evenly distributed springs are fixed to the lower side of the first rubber sealing frame, and all springs are fixed inside the connecting groove. A groove is provided on the lower side of the upper cover, and the upper end of the first rubber sealing frame is located inside the groove. The gap between the upper cover and the box body is completely sealed by setting a sealing assembly and dispensing.

The connecting frame is fixed on the lower side of the box body, the interior of the connecting frame is filled with thermally conductive sealant, the thermally conductive plate is connected to the connecting frame through the thermally conductive sealant, and the lower side of the thermally conductive plate is fixed with evenly distributed thermally conductive fins, and heat is dissipated by setting up a heat dissipation component.

[0014] 2. A heat dissipation solution that combines thermal sealant, thermal fins, and an active exhaust fan completely seals the enclosure while quickly dissipating internal heat and forcing convection for heat dissipation. This solves the common heat dissipation problem in high-protection systems and prevents component performance degradation or damage caused by high temperatures.

[0015] 3. Through blind hole screw fixation and detachable mounting frame design, convenient disassembly and assembly are achieved while ensuring the sealing of the connection, which facilitates the maintenance and replacement of key components and significantly reduces the system maintenance cost in complex outdoor environments.

The lower side of the heat conducting plate 63 is fixed with evenly distributed heat conducting fins 64. Heat dissipation is performed by setting the heat dissipation assembly 6.

[0025] Among them: a mounting frame 7 is provided on the lower side of all heat conducting plates 63, the mounting frame 7 is fixed to the lower side of the corresponding heat conducting plate 63, and an exhaust fan 8 is installed inside the mounting frame 7, and the exhaust fan 8 is provided to improve the heat dissipation effect.

Differential deformation; finally, the second sealing rubber frame 9 on the inner side of the upper cover 2 is embedded in the interior of the box 1 to further block the penetration of water vapor and dust, forming triple redundant protection. In terms of heat dissipation, the heat inside the box 1 is transferred to the heat conducting plate 63 through the thermal conductive sealant 62, and the heat dissipation area is expanded by the thermal fins 64. At the same time, the exhaust fan 8 in the mounting frame 7 drives the airflow to accelerate the diffusion of heat, ensuring that the system can still dissipate heat efficiently in a closed environment. In addition, modular design such as the detachable connection between the exhaust fan 8 and the mounting frame 7 reduces the difficulty of maintenance of key components while maintaining sealing, thereby ensuring long-term operational stability.
