Abstract

The invention discloses a T-shaped ventilator, and relates to the technical field of ship processing and manufacturing. The ventilator comprises a cylinder body, a bearing beam, a hood cover plate anda force application mechanism. The hood cover plate comprises two sub-cover plates, the two sub-cover plates are arranged on two sides of the bearing beam respectively, and each sub-cover plate is connected with a rotating device arranged on the bearing beam; and the force application mechanism comprises a follow-up rod and an operating handle, the follow-up rod comprises a fixed end and a free end, the fixed end and each sub-cover plate are relatively fixed, and the operating handle is arranged at the free end. The force application mechanism is adopted to drive the two sub-cover plates to rotate around the rotating device; the operating handle, the follow-up rod and the sub-cover plate in the force application mechanism form a lever structure; and an arm of force of the operating handleis larger than that of the sub-cover plate, the operating handle can be driven to move only by applying a force smaller than the gravity of the sub-cover plate to the operating handle, the hood coverplate can be opened and closed quickly, labor can be saved, and opening and closing time of the hood cover plate can be saved.

Description

Technical field [0001] This application relates to the technical field related to ship processing and manufacturing, and in particular to a T-shaped ventilator. Background technique [0002] T-shaped ventilators are the main air outlets for cargo hold ventilation. The cargo holds mainly use T-shaped ventilators to convey fresh air to ensure the normal circulation of air in the cargo hold and the normal operation of refrigerated containers in the cargo hold. Existing more common T-shaped ventilating tube, its structure diagram is as follows figure 1 As shown, the opening and closing device mainly adopts the form of a hand wheel 1, and the rotation of the hand wheel 1 drives the screw 2 to control the lifting of the hood cover 3 to realize the opening and closing of the T-shaped ventilator. However, this type of T-shaped ventilating cylinder that relies on the hand wheel 1 to open and close requires manual rotation of the hand wheel 1 for multiple turns, which causes the opening an...
