In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a pipe altogether of automatically controlled diesel engine of boats and ships, includes the pipe altogether, the pipe altogether comprises inner tube and outer tube, the inner tube is concrete defeated oil pipe, the outer tube is the protecting tube, through division board fixed connection between inner tube and the outer tube, the division board is ring dress structure, just division board quantity is a plurality of, and the equidistance is arranged in proper order along the extending direction of the pipe altogether, the outer tube is still through arranging oil pipe fixed connection storage oil tank, be provided with solenoid valve on the oil pipe, it has a plurality of gas sensor to go back fixed mounting on the outer tube, gas sensor signal connection alarm.
As a further aspect of the present invention: the inner part of the outer pipe is separated into a plurality of small cavities by the partition plates, the small cavities are all in a vacuum state, and each small cavity is connected with an oil discharge pipe and a gas sensor.
As a further aspect of the present invention: the oil storage tank is specifically made of soft leather materials, and a spring is fixedly arranged in the oil storage tank.
As a further aspect of the present invention: the gas sensor is specifically an alkane sensor.
As a further aspect of the present invention: the inside of the storage oil tank is in a negative pressure state.
Compared with the prior art, the beneficial effects of the utility model are that: can effectively protect common rail pipe leakage back high pressure fuel injection to cause the harm to people or engine, common rail pipe guard shield is airtight structure, can collect the fuel of leaking and report to the police, prevents that the fuel from causing the pollution to the engine, simultaneously because the design of protective tube makes boats and ships can continue to use under defeated oil pipe cracked condition.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to the drawings without creative efforts.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1 inner tube, 2 outer tubes, 3 division plates, 4 oil discharge tubes, 5 storage oil tanks, 6 electromagnetic valves, 7 gas sensors and 8 springs.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, in an embodiment of the present invention, a common rail pipe of an electrically controlled diesel engine for a ship includes a common rail pipe, the common rail pipe consists of an inner pipe 1 and an outer pipe 2, the inner pipe 1 is a concrete oil conveying pipe, the outer pipe 2 is a protective pipe, the inner pipe 1 and the outer pipe 2 are fixedly connected through a partition plate 3, the partition plate 3 is in a circular ring structure, and the isolation plates 3 are arranged in equal distance along the extending direction of the common rail pipe, the outer pipe 2 is fixedly connected with a storage oil tank 5 through an oil discharge pipe 4, an electromagnetic valve 6 is arranged on the oil discharge pipe 4, a plurality of gas sensors 7 are fixedly arranged on the outer pipe 2, 7 signal connection alarms of gas sensor, it is worth noting, every gas sensor 7 all corresponds and is provided with the reference numeral, can be used for the damaged area of quick discernment inner tube 1.
It is worth noting that the inner part of the outer pipe 2 is separated into a plurality of small cavities by a plurality of partition plates 3, the small cavities are all in a vacuum state, and each small cavity is connected with an oil discharge pipe 4 and a gas sensor 7.
It should be noted that the storage oil tank 5 is made of soft leather material, and a spring 8 is fixedly installed inside the storage oil tank 5.
Notably, the gas sensor 7 is specifically an alkane sensor.
It is to be noted that the inside of the storage oil tank 5 is in a negative pressure state.
The working principle is as follows:
in a specific practical process, once the inner oil conveying pipe is broken, diesel oil can be immediately leaked, and due to the existence of the partition plate 3, the gas sensor arranged in the small cavity area can immediately detect volatile alkane gas so as to give an alarm to people, and a user can be helped to quickly find a damaged area;
meanwhile, due to the existence of the external protective pipe, diesel oil cannot be leaked to a dangerous area even if the internal oil conveying pipe is broken in time, and the space needing to be filled when the diesel oil is leaked is reduced due to the arrangement of the partition plate 3, so that the area can be quickly filled with the diesel oil, oil supply is continued, and air does not enter an engine of a ship due to the fact that the inside of the protective pipe is in a vacuum state, so that the ship can be allowed to run emergently under the condition that the internal oil conveying pipe is broken, and the maintenance or the replacement can be carried out after waiting for a proper time;
in the subsequent maintenance or replacement process, the leaked oil in the outer pipe 2 can be discharged into the storage oil tank 5 through the electromagnetic valve 6 and the oil discharge pipe 4, and the leaked oil can be easily sucked into the storage oil tank 5 due to the fact that the interior of the storage oil tank 5 is in a negative pressure state.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
