Description

Novel marine waterproof type air funnel

Technical Field

The utility model relates to a design and the production field of boats and ships equipment, the more specifically novel marine waterproof type draft tube that says so.

Background

The ventilating funnel is a main part for ventilating the cabin of a modern ship, the ventilating form of the cabin comprises natural ventilation, mechanical ventilation and air conditioning ventilation, wherein the natural ventilation is the most common and is also the most widely used mode, the ventilating funnel is generally arranged on an open deck in the application process of the natural ventilation, and the ventilating funnel usually adopts a shutter or a grille to realize the waterproof function in use, so the waterproof performance is poor, and the opening or closing operation is inconvenient.

Chinese patent: a waterproof half gooseneck type ventilating duct (application publication No. CN110884638A) is disclosed, which can effectively realize waterproof effect and is safe and convenient to operate under the condition of ensuring the ventilating effect.

However, the solution still has the following defects in application, namely the cover plate of the solution is arranged outside the ventilating duct, and is required to be screwed upwards to close the ventilating duct when in use and is screwed downwards to be arranged below the outside of the ventilating duct when not in use. The structure not only occupies a space, but also the waterproof cover plate is exposed outside and is easy to be blown by sea wind, exposed to the sun and washed by rainwater, so that the waterproof part of the cover plate is aged and damaged, and the service life of the waterproof part is shortened.

Therefore, the ventilation barrel which is more reasonable in structure, more convenient to use and more practical in structure is designed, and the ventilation barrel has higher application value.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a novel marine waterproof type draft tube, its main aim at overcome the above-mentioned not enough and shortcoming that prior art exists.

The utility model adopts the technical scheme as follows:

a novel marine waterproof ventilating duct comprises a longitudinal ventilating duct body and a transverse bending duct body, wherein the upper end of the longitudinal ventilating duct body is connected with the left end of the transverse bending duct body in a matched mode, the right end of the transverse bending duct body is bent downwards, and an opening is downward; a rotatable rotary rod penetrates through an opening in the upper portion of the longitudinal ventilation cylinder, a wind shield is installed on the rotary rod in a matched mode, the wind shield can be matched with the blocking cover in a turnover mode in the longitudinal ventilation cylinder, and a rotary disk used for driving the rotary rod to rotate is installed at the outer end portion of the rotary rod in a matched mode.

Furthermore, an inclined opening is formed in the upper end of the longitudinal ventilation cylinder, and the rotating rod is arranged in the middle of the inclined opening in a penetrating mode in a matching mode.

Further, the inclined angle of the inclined opening is 45 degrees.

Furthermore, a positioning rotating piece is arranged on the rotating disc and used for fixing and positioning the rotating angle of the rotating bar.

Furthermore, the outer periphery of the wind shield is wrapped with a sealing ring which is matched and sealed with the inner wall of the longitudinal ventilation cylinder.

Furthermore, a waterproof grid is arranged at the opening of the transverse bending cylinder body.

Through the above-mentioned right the utility model discloses a description compares with prior art, the advantage of the utility model lies in:

the utility model discloses a set up rotary disk below rotary rod, the deep bead, can be in order to realize opening an account, switching on and functions such as waterproof to the draft tube, can prevent its influence that receives external environment to the protection of deep bead subassembly better moreover, improve its life and result of use.

Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1 to 3, a novel marine waterproof vent pipe comprises a longitudinal vent pipe body 1 and a transverse bent pipe body 2, wherein the upper end of the longitudinal vent pipe body 1 is connected with the left end of the transverse bent pipe body 2 in a matched manner, and the right end of the transverse bent pipe body 2 is bent downwards and has a downward opening; a rotatable rotary rod 3 penetrates through an opening at the upper part of the longitudinal ventilation cylinder body 1, a wind shield 4 is arranged on the rotary rod 3 in a matching mode, the wind shield 4 can be matched with a blocking cover in a turnover mode in the longitudinal ventilation cylinder body 1, and a rotary disk 5 used for driving the rotary rod 3 to rotate is further arranged at the outer end part of the rotary rod 3 in a matching mode.

Furthermore, an inclined opening 11 is formed in the upper end of the longitudinal ventilation cylinder 1, and the rotating rod 3 is arranged in the middle of the inclined opening 11 in a penetrating mode in a matching mode.

Further, the inclined angle of the inclined opening 11 is 45 degrees.

Furthermore, a positioning rotating member 6 is disposed on the rotating plate 5 for fixing and positioning the rotating angle of the rotating rod 3.

Furthermore, the outer periphery of the wind shield 4 is wrapped with a sealing ring 41, and the sealing ring 41 is matched and sealed with the inner wall of the longitudinal ventilation cylinder 1.

Furthermore, a waterproof grid 21 is arranged at the opening of the transverse bending cylinder 2.

The utility model discloses a use method:

and (3) conducting air flow of the ventilating duct: through this rotary disk of rotation, make the rotary rod rotate, and install the deep bead on the rotary rod and drive and overturn by the rotary rod, after rotatory certain angle, it is fixed with the location rotating member on the rotary disk again, at this moment, the angle of rotary rod is fixed, and the angle of deep bead is fixed simultaneously, realizes that the air current of draft tube switches on.

Air flow of the ventilating duct is closed: the positioning screwing piece on the rotating disc is opened firstly, then the rotating disc is rotated to enable the rotating rod to rotate, the wind shield arranged on the rotating rod is driven by the rotating rod and overturned, after the rotating rod rotates to a certain angle, the wind shield closing cover is arranged in the ventilating duct, the airflow of the ventilating duct is closed, and at the moment, the positioning screwing piece is fixed, and the operation is completed.
