Waterproofing Animatronic Dinosaurs for Outdoor Exhibitions | Key Points for Waterproof Design of Outdoor Animated Dinosaurs

Water arrives from four directions

Rain from above, splash from the ground, humidity in the air and condensation inside the body. Most failures come from the last two, because they are invisible until electronics corrode. A waterproof build addresses all four, not just the top surface.

The enclosure is the first line

Control boxes, power supplies and actuators belong in sealed enclosures with rated cable glands. Cables should enter from below with a drip loop, never from the top. A perfect seal on the box is useless if water runs down the cable into it.

Drainage and venting together

Sealed bodies trap heat, and trapped heat meets cool air as condensation. Vents with filters and slight positive pressure reduce internal moisture. Where drainage paths exist, they need low points that actually drain, not pockets that collect water.

Materials age differently outdoors

Silicone, paint, steel and fasteners all weather at different rates. Stainless fasteners and protective coatings cost more up front and save far more in maintenance. Check the specification for the joints, because that is where corrosion starts.

Seasonal inspection pays for itself

Outdoor exhibits need a routine before and after the wet season: seals, drains, vents, cable glands and internal inspection points. A short checklist executed twice a year prevents most of the failures that take a dinosaur off display.

DinoCG builds outdoor animatronic units with sealed enclosures, drainage planning and inspection access, and supplies the seasonal checklist with the installation.

水从四个方向来

上方下雨、地面溅水、空气中的湿气，以及机体内部凝结。多数故障来自后两种，因为它们直到电子件被腐蚀才被发现。防水设计要同时应对四个方向，而不是只处理顶面。

箱体是第一道防线

控制箱、电源和执行机构应放进密封箱体，并使用带防护等级的电缆接头。线缆应从下方进入并做滴水弯，绝不从上往下穿。箱体密封再好，水顺着线缆流进去也白搭。

排水和透气要一起做

完全密封的机体内部会积热，热空气遇到冷壁就凝结。带滤芯的透气孔和轻微正压能降低内部湿度。需要排水的位置要有真正能排掉的最低点，而不是积水凹槽。

材料在户外老化速度不同

硅胶、涂料、钢材和紧固件的老化速度各不相同。不锈钢紧固件和防护涂层前期更贵，但在维护上省得更多。要特别检查接合部位的规格，因为腐蚀通常从这里开始。

季节性检查最划算

户外展项在雨季前后各做一次例行检查：密封、排水、透气、电缆接头和内部检查口。一年两次的短清单，能避免大部分让恐龙停展的故障。

DinoCG 的户外仿真装置采用密封箱体、排水规划和可检修结构，并随安装交付季节性检查清单。
