The invention relates to the technical field of underwater equipment, in particular to an underwater semi-open type space sealing device which comprises a box body, an upper cover, a steering engine, racks and a gear, the steering engine, the racks and the gear are installed in the box body, the gear is connected with the steering engine, the four racks are perpendicularly arranged and all connected with the gear, and the thickness of the tail ends of the racks gradually becomes thicker from outside to inside. The vertical section of the upper cover is of an inverted-U-shaped structure, grooves corresponding to the four racks are formed in the four side walls of the upper cover respectively, when the steering engine drives the gear to rotate and the racks move forwards, the tail ends of the four racks can stretch into the grooves of the upper cover, and in the process that the four racks enter the grooves of the upper cover, the racks become thicker and thicker. As the rack is always on the same horizontal plane, the upper cover is driven to press downwards, four downward pressures are applied to the upper cover, and the upper cover and the box body are tightly pressed together. According to the invention, a good sealing effect of an underwater semi-open space can be realized.
本发明涉及水下装备技术领域,具体涉及一种水下半开放式空间密封装置,包括箱体、上盖以及安装在箱体内的舵机、齿条和齿轮,所述齿轮与舵机相连,四根齿条相互垂直布置,均与齿轮连接,所述齿条的末端厚度从外往里逐渐变厚,所述上盖的竖截面呈倒类U形结构,其四个侧壁上分别开设有与四根齿条对应的槽,所述舵机带动齿轮旋转,齿条向前移动时,四根齿条的末端均会伸进上盖的槽中,在四根齿条进入上盖的槽的过程中,随着齿条越来越厚,由于齿条始终在一个水平面上,将带动上盖下压,对上盖施加4个向下的压力,将上盖与箱体紧紧压在一起。本发明可实现水下半开放式空间的良好封闭效果。
