Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a depth sounding ventilating device on a ship. Background Art

[0002] Ship is a general term for various vessels. A ship is a means of transportation that can sail or anchor in waters for transportation or operations. It has different technical performance, equipment and structural types according to different usage requirements.

[0003] Sounding pipes and vent pipes are installed in ship oil tanks. The function of the vent pipe is to maintain pressure balance between the inside of the oil tank and the outside atmosphere, to avoid excessive pressure difference during loading, unloading or temperature changes, which may damage the oil tank structure or affect operational safety. It helps to discharge the evaporated oil and gas in the oil tank into the atmosphere, reduce the oil and gas concentration in the tank, and reduce potential dangers. The function of the sounding pipe is to allow the crew to accurately understand the depth or amount of oil in the oil tank through special measuring tools, so as to make effective fuel management and operational decisions, and promptly discover abnormal changes in the liquid level in the oil tank to ensure the safe operation of the ship.

[0004] Prior art such as CN203419242U, the utility model discloses a vent pipe overflow prevention device for a ship fuel tank, including a buffer cylinder, the two ends of the buffer cylinder are respectively an inlet end and an outlet end, the inlet end and the outlet end are respectively connected to the vent pipe and the vent cap, and the inner walls on both sides of the buffer cylinder are provided with cross-arranged overflow baffles. The utility model installs a buffer between the vent pipe and the vent cap and installs a sway control bulkhead in the cabin to prevent oil from directly overflowing through the vent pipe, which solves the problem that when the ship is sailing, due to the presence of wind and waves on the sea, the ship must have pitch and roll, and at the same time, the top of the fuel storage tank is the main deck. According to this type of ship, the vent pipe can only be installed on the main deck. If the ship pitches and rolls, it will definitely cause the oil in the cabin to vibrate and overflow to the main deck through the vent pipe.

[0005] In daily work, it is found that when the existing depth sounding and ventilation devices are in use, oil vapor will be generated due to the excessively high temperature in the oil tank. The oil vapor will be discharged into the outside through the ventilation pipe. When discharged, the oil in the oil vapor cannot be collected, resulting in the oil being discharged into the outside along with the steam, causing a waste of resources and easily polluting the environment. This in turn leads to the problem that the existing depth sounding and ventilation devices are not convenient for collecting and reusing the oil in the discharged oil vapor. Utility Model Content

The extension pipe is inclined, and the oil will flow into the collecting hood for collection.

[0008] Preferably, a return pipe is fixedly connected to the lower surface of the collecting hood, and the other end of the return pipe is fixedly connected to the surface of the air permeable tube body. Through the above components, the oil collected by the collecting hood can flow into the air permeable tube body and the sounding tube body through the return pipe and flow back to the oil tank after being filtered by the filter assembly.

[0009] Preferably, the auxiliary pipe is formed by combining a hollow pipe and bell mouths on both sides of the hollow pipe. Through the above components, the bell mouths in the auxiliary pipe can better guide steam into the hollow pipe for cooling operation.

Through the above components, the clamp can be rotated so that the groove on the surface of the clamp is inserted into the handle, thereby limiting the position of the handle and the filter.

[0013] Preferably, one end of the extension tube is fixedly connected with a shielding net, and through the above-mentioned components, the shielding net can prevent impurities from entering the extension tube.

[0014] Preferably, a well is arranged around the connection between the sounding pipe body and the oil tank deck. The well is surrounded by metal plates, the bottom of which is fixed to the deck, the surrounding areas are sealed, and the top is hollow.

[0015] Compared with the prior art, the advantages and positive effects of the utility model are:

[0016] 1. In the utility model, by setting a collecting device, the auxiliary pipe and the auxiliary parts can be cooled by using a condenser.
