ship side propeller pipe tunnel convenient to overhaul

Technical Field

The utility model relates to a boats and ships energy saving and emission reduction technical field especially relates to kinds of boats and ships side direction propeller pipe tunnel convenient to overhaul.

Background

In the ship navigation technology, in order to reduce the resistance when a ship is in straight navigation, a technology of additionally arranging side push pipe tunnel sealing covers at two ends of a ship side push tunnel can be adopted, and most ships are still not willing to be provided with the side push pipe tunnel sealing covers because the existing side push pipe tunnel sealing cover technology is low in cost-efficiency ratio, single in performance , high in failure rate and large in occupied space of an actuating mechanism and cannot be arranged.

Among the existing side push pipe tunnel technology, the common kinds of troubles are that the maintainer can not enter the side push pipe tunnel to overhaul the side propeller when the ship is parked on water, so if the side propeller needs to be overhauled, the ship still needs to be parked and enter a dry dock, thereby causing operation loss and paying extra large amount of dry dock cost.

SUMMERY OF THE UTILITY MODEL

In view of there being the above-mentioned not enough at present, the utility model provides a kinds of boats and ships side direction propeller pipe tunnels convenient to overhaul, the maintainer can directly get into the side direction propeller pipe tunnel of the sea water of evacuation in can following the manhole in the cabin, inspects and maintains the side direction propeller, has avoided in the past the side direction propeller must enter the state that the dry dock could overhaul, has saved huge dry dock expense and the time of shutting down for the shipowner.

In order to achieve the above object, the embodiments of the present invention adopt the following technical solutions:

boats and ships side direction propeller pipe tunnel convenient to overhaul, the both ends port department of pipe tunnel is equipped with watertight , watertight connects the setting at pipe tunnel both sides port through articulated formula, be equipped with drainage system in the pipe tunnel, pipe tunnel upper end is equipped with the manhole, manhole and side direction propeller cabin intercommunication, be equipped with the manhole cover on the manhole, the manhole upper end is equipped with the flange, be equipped with positioning mechanism on flange and the manhole cover.

According to the utility model discloses an aspects, positioning mechanism includes two fixed blocks of symmetry fixed connection on the flange, be equipped with the locating piece on the fixed block, the symmetry is equipped with two second fixed blocks that correspond with the fixed block on the manhole cover, the downside of second fixed block be equipped with locating piece complex constant head tank.

According to aspects of the utility model, the symmetric welding has two handles on the manhole cover.

According to aspects of the present invention, the bolt and nut are a hex bolt and a hex nut, respectively.

The utility model discloses the advantage of implementing:

1. can be after closing watertight , through the sea water in the exhaust pipe tunnel of drainage system evacuation pipe to the maintainer can directly get into the side direction propeller pipe tunnel of the sea water of having emptied in the manhole in the cabin, inspect and maintain the side direction propeller, avoided the state that the side direction propeller must enter the dry dock and just can overhaul in the past, saved huge dry dock expense and the time of stopping a journey for the shipowner, increase boats and ships availability factor, create cost saving and extra operating value of tens of millions.

2. Be connected through flange and manhole cover to bolt and nut through a plurality of equidistant settings make the manhole cover closely inseparabler and firm with the manhole connection, through the sealing washer that sets up, increase the seal in manhole, avoid leaking.

3. Through the location structure that structures such as fixed block, second fixed block, locating piece, constant head tank constitute for the manhole cover easily matches with the flange position when dress manhole cover, thereby the bolt and nut of being convenient for connect, and it is more convenient to install.
