Description
Technical Field
The invention belongs to the technical field of ships, and particularly relates to a single pendulum type disturbance and power generation device for a crude oil ship by utilizing roll.
Background
Crude oil is an important energy source, and the demand of crude oil is increasing in countries around the world. At present, the main crude oil production countries are brazil, illite, sauter Arabia and other countries, the produced crude oil is transported to various places in the world, and the transportation of the crude oil mainly depends on a crude oil transport ship (crude oil ship for short).
The crude oil is transported by the crude oil carrier generally in a longer route, for example, the route from the Jidagang of Sha Tea to the Qingdan port of China is about 6000 knots, the crude oil generally needs to travel for more than 20 days, and contains a lot of particles or impurities with higher density. In addition, as the temperature of the seawater in the north is lower, particularly in winter, the temperature of the seawater is close to about 0 ℃, so that the heat exchange speed of the oil at the bottom of the liquid cargo tank through the bottom plate of the ship and the seawater is increased, the temperature of the oil at the bottom of the liquid cargo tank is lower, and the viscosity of the oil at the bottom of the liquid cargo tank is greatly increased. In addition, a heating system is not generally arranged on the crude oil ship, when the crude oil ship arrives at a port for unloading, as the oil at the bottom of the liquid cargo tank is thick, the resistance of the unloading pump when unloading the oil at the bottom of the liquid cargo tank is large, so that the sucking difficulty of the unloading pump is high, and even the phenomenon of suck-out of the unloading pump can occur when the sucking difficulty of the unloading pump is severe, so that the sucking difficulty of the unloading pump caused by the thick oil at the bottom of the liquid cargo tank is a relatively outstanding problem existing when the crude oil ship is unloaded.
When the crude oil ship is sailing on the sea, the ship can roll due to the influence of factors such as waves, so that the ship body can shake left and right, and the rolling motion of the ship can be more severe especially under severe weather conditions. Although the rolling motion of the ship is severe, this has little effect on the fluidity of the crude oil in the tank, for the following specific reasons: the crude oil in the liquid cargo tank is usually loaded to occupy the whole hold, the top of the liquid cargo tank has a very small part of free space, the depth of the liquid cargo tank is very deep, generally 20-30 meters, when the ship rolls, only the upper surface oil flows to the port or starboard along with the roll motion of the ship, and most of the oil below the surface oil in the liquid cargo tank (namely, the oil at the middle and lower parts) hardly flows, so that the roll motion of the ship hardly causes disturbance to the oil at the middle and lower parts in the liquid cargo tank. When the ship rolls, impurities and particles in crude oil can be continuously precipitated to the bilge just because the fluidity of oil in the liquid cargo tank is poor, so that the oil at the bottom of the liquid cargo tank is sticky. In addition, the viscosity of the oil at the bottom of the cargo tank is greatly increased due to the relatively low oil temperature at the bottom of the cargo tank.
The rolling motion of the vessel causes a large amount of available mechanical energy to be contained on the vessel. Based on this, if a single pendulum type disturbance and power generation device of crude oil ship utilization roll can be put forward, through this device to the fluid in the liquid cargo tank disturbance, the crude oil ship unloading difficulty's that will solve the thick and cause of liquid cargo tank bottom fluid problem can also retrieve the mechanical energy that produces when the boats and ships roll and be used for the electricity generation, because the roll of boats and ships is caused by the wave, this device is also to the indirect utilization of wave energy to the recovery of mechanical energy in essence, this device will have good practical application value.

In addition, in the crude oil ship navigation process, the hydraulic turbine can make the fluid intensive mixing of liquid cargo tank upper portion, middle part and bottom in to the disturbance effect of fluid, makes the fluid upper and lower temperature keep unanimous, avoids liquid cargo tank bottom fluid temperature too low, further increases the viscosity of liquid cargo tank bottom fluid. In addition, the impeller of the water turbine and the oil in the liquid cargo tank are mutually rubbed in the working process to generate heat energy, so that the oil is heated, and the viscosity of the oil at the bottom of the liquid cargo tank is further reduced. Meanwhile, the device can also recycle mechanical energy generated during ship rolling, and further convert the recycled mechanical energy into electric energy, so that the device can indirectly utilize wave energy.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent.
A single pendulum type disturbance and power generation apparatus for a crude oil carrier utilizing roll, as shown in figures 1 and 2, the apparatus comprising: the device comprises a base 1, a limiting plate 2, a rotating shaft 3, a swinging rod 4, a water turbine 5, a generator 6, a transmission shaft 7 and a rolling bearing 8.
As shown in fig. 3, in general, the crude oil carrier is provided with a plurality of longitudinal bulkheads in order to reduce the influence of the free liquid surface on the stability of the ship. The invention is described by taking a right side compartment (a cargo tank near the starboard of a ship) formed by arranging 1 longitudinal bulkhead as an example:
the base 1 is provided with two circular through holes, the two circular through holes are positioned on the same axis, the base 1 is ensured to be fixed at the middle position of the top of the cargo tank during installation, the axes of the two circular through holes are parallel to the ship length direction, and rigid welding is adopted between the base 1 and the cargo tank; the limiting plate 2 is fixedly arranged below the base 1, the cross section of the limiting plate 2 (the cross section is parallel to the middle cross section of the ship) is isosceles trapezoid, according to practical conditions, the included angle between two sides of the isosceles trapezoid can be designed according to the specific size of the cargo tank, the limiting plate 2 can be made of materials with good impact resistance and elasticity, and spring steel is preferably selected.
The number of the rolling bearings 8 is two, and the outer rings of the two rolling bearings 8 are matched with the circular through holes of the base 1 and are in interference fit; the rotating shaft 3 is matched with the inner rings of the two rolling bearings 8, and interference fit is adopted; the upper end of the swing rod 4 is rigidly welded with the rotating shaft 3; the generator 6 is arranged at the lower end of the swing rod 4, a circular through hole is formed in the axial direction of the generator 6, and the axial direction of the generator 6 is always vertical to the ship length direction during installation; the transmission shaft 7 passes through a circular through hole of the generator 6, and the transmission shaft 7 is in watertight connection with the generator 6; the two water turbines 5 are all fixedly connected with two ends of the transmission shaft 7 respectively, and the two water turbines 5 are symmetrically arranged on two sides of the generator 6.
Furthermore, the impeller of the water turbine 5 and the shell of the generator 6 are made of corrosion-resistant materials (such as cast steel) with higher density, the shell of the generator 6 can be thicker, the shell thickness of the generator 6 is at least more than 20mm, so that the total weight of the water turbine 5 and the generator 6 is increased, the water turbine 5 and the generator 6 play a role of heavy objects, and the roll force generated by the device in the rolling process can be ensured to be larger, so that the disturbance effect of the water turbine 5 on oil is better, and the generated energy of the generator 6 is also larger. The invention selects the material with higher density to make the volume of the generator 6 smaller, and when the swing rod 4 moves in a single pendulum due to the rolling motion of the ship, the resistance of the oil liquid to the motor can be properly reduced when the motor swings left and right.
The following is a detailed description of the deployment of the device according to the specific operating conditions of the ship when rolling movements occur:
the generator 6 and the water turbine 5 in the device are subjected to gravity to keep the pendulum rod 4 in a vertical state perpendicular to the sea level all the time, whether the ship is in rolling motion or in a forward floating state, which is defined as an initial state in the invention.
When the ship is in a forward floating state, the ship does not lean left or lean right, the device is in an initial state, and is kept relatively static for the cargo tank, and the swing rod 4 does not do simple pendulum motion, so that the blades of the water turbine 5 do not rotate. Therefore, the hydraulic turbine 5 does not generate disturbance action on the oil in the liquid cargo tank in the forward floating state of the ship, and the generator 6 is not driven to generate electricity.
When a ship performs rolling motion during sailing, as shown in fig. 4, a ship is first taken as an example of rolling left: when the ship leans left, the liquid cargo tank is used as a reference, the swing rod 4 swings from an initial state to the left limit position, so that the swing rod 4 and the ship can move relatively, the swing rod 4 does single swing motion leftwards relative to the liquid cargo tank, the water turbine 5 is driven to rotate, and the fluidity of oil in the liquid cargo tank can be increased in the process of swinging back and forth by the water turbine 5. Simultaneously, the transmission shaft 7 and the water turbine 5 coaxially rotate, and then the generator 6 is driven to generate electricity.
When the ship swings rightwards, the swing rod 4 swings rightwards relative to the cargo tank from the left limit position to the right limit position, so that the device and the ship generate relative motion, and the swing rod 4 swings rightwards relative to the cargo tank to drive the water turbine 5 to rotate. The oil in the liquid cargo tank can be disturbed by the back and forth swing of the water turbine 5. Simultaneously, the transmission shaft 7 and the water turbine 5 coaxially rotate, and then the generator 6 can be driven to generate electricity.
In practice, the left tilting and the right tilting of the ship are always continuously and alternately carried out, so that the device can continuously disturb the oil in the liquid cargo tank when the ship rolls, the mobility of crude oil in the liquid cargo tank is greatly increased, impurities and particles in the crude oil are prevented from precipitating to the bilge due to poor mobility of the oil in the liquid cargo tank, the viscosity of the oil at the bottom of the liquid cargo tank is increased, the problem of difficult unloading of a crude oil ship due to viscous oil at the bottom of the liquid cargo tank is solved, and the device can continuously generate electricity, so that the generated electricity can be used for part of electric equipment on the ship.
Furthermore, the device adopts the symmetrical arrangement of the two water turbines 5, and when the ship rolls, the two water turbines 5 coaxially rotate, so that the mechanical energy generated by the rolling motion of the ship can be more effectively recovered, and the power generation effect is greatly improved.
When the ship sails, the ship can roll due to the influence of factors such as waves, and a large amount of available mechanical energy is contained in the ship due to the roll motion of the ship. The invention can recover the mechanical energy generated when the ship rolls, further convert the mechanical energy into electric energy, and substantially indirectly utilize the wave energy, thereby solving the problem that the ship sails difficultly to utilize the wave energy.
When the crude oil carrier sails on the sea, the temperature of the sea water is lower, especially in winter, the temperature of the sea water can be even close to 0 ℃, so that the heat exchange speed of the oil at the bottom of the liquid cargo tank through the bottom plate of the ship and the sea water is increased, the temperature of the oil at the bottom of the liquid cargo tank is lower, and the viscosity of the oil at the bottom of the liquid cargo tank is greatly increased. The crude oil ship is not provided with a heating system generally, and the hydraulic turbine 5 is utilized to disturb the oil liquid, so that the oil liquid at the upper part, the middle part and the bottom in the liquid cargo tank is fully mixed, the upper temperature and the lower temperature of the oil liquid in the liquid cargo tank are kept consistent, and the viscosity of the oil liquid at the bottom of the liquid cargo tank is prevented from being increased due to lower temperature of the oil liquid at the bottom of the liquid cargo tank. In addition, the impeller of the water turbine 5 and the oil in the liquid cargo tank are mutually rubbed in the working process to generate heat energy, so that the oil is heated, and the viscosity of the oil at the bottom of the liquid cargo tank is further reduced.
As shown in fig. 5, according to a specific ship length and length of the cargo tank, a plurality of the devices can be installed in a single cargo tank along the ship length direction, so that when the ship rolls, especially in stormy weather, the energy which can be recovered by the device is huge, and the power generation effect and the disturbance effect of the device can be better improved.
In conclusion, the viscosity of the bottom oil in the liquid cargo tank can be effectively reduced, and the method has good practical application value for solving the problem of difficult suction of the unloading pump caused by too viscous oil at the bottom of the liquid cargo tank.
The principle and the installation mode of the invention are described by taking 1 longitudinal bulkhead and the right bulkhead as an example, and the installation mode and the principle of the invention on the left bulkhead are the same as those of the right bulkhead. In addition, there are generally a large number of cargo tanks of a large crude oil tanker, each of which can be equipped with the apparatus according to the invention as described above.
The foregoing is merely a preferred embodiment of the present invention, but is not limited to the examples described above, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the invention.
