Technical Field
The invention relates to a pulse generating device matched with a hydraulic flushing station.
Background
The shipbuilding industry has developed at a high speed in recent decades, the scale of the transportation industry is enriched, and the economic development is promoted. Among the prior art on the ship have a lot of pipelines, these pipelines inner wall can produce a large amount of impurity and remain after long-term the use, if not carry out timely processing to these residues and will cause very big damage to the pipeline, simultaneously, the impurity pollutant still can cause the damage of key components and parts through the pipeline gets into hydraulic components and parts, influences the normal function of boats and ships, causes huge economic loss. At present, an external cleaning pump station is often adopted to clean a hydraulic pipeline of a ship regularly to remove impurity pollutants in the pipeline. During the cleaning operation, the turbulence level of the flushing hydraulic oil in the pipeline is a key index for measuring the cleaning capacity. In the conventional hydraulic cleaning station, an electromagnetic overflow valve is often connected in parallel to a main oil pump group, and a part of flow in a main pipeline is gradually overflowed into an oil tank, so that hydraulic pulse flow with alternative flow and pressure is formed in a cleaning pipeline, and the turbulence degree of hydraulic oil in the pipeline is greatly increased. However, such a method will generate a large overflow loss, and a considerable portion of the flow will flow back to the oil tank through the overflow valve, which also causes waste of electric energy resources.

Detailed Description
The invention is further illustrated by the following figures and examples in conjunction with the description:
the ship pipeline flushing pulse generating device is connected in a flushing pipeline in series and comprises a shell 1, an adjusting block 2 and a driving mechanism 3, wherein the shell is cylindrical, an oil inlet 11 is formed in one side of the peripheral side wall, and an oil outlet 12 is formed in the opposite side of the peripheral side wall; the adjusting block is cylindrical and is rotatably and coaxially arranged in the shell, the diameter of the adjusting block is smaller than the inner diameter of the shell, and an arc-shaped flow channel 4 is formed between the peripheral side surface of the adjusting block and the inner wall of the shell; the adjusting block 2 is provided with a flow hole 21 in a radial direction in a penetrating manner, and the peripheral side surface of the adjusting block is provided with a butt joint pipe 22 opposite to the flow hole; the adjusting block rotates, so that when the butt joint pipe is aligned with the oil inlet and the oil outlet, the flushing pipeline forms a large flow; when the adjusting block rotates to enable the butt joint pipe to be completely staggered with the oil inlet and the oil outlet, the butt joint pipe is blocked by the inner wall of the shell, the oil inlet is communicated with the oil outlet through the arc-shaped flow passage, and the flushing pipeline forms small flow; the middle part of the adjusting block 2 is connected with a rotating shaft 23 which penetrates through the shell and extends to the outer side of the shell, and the driving mechanism 3 is connected with the rotating shaft; the driving mechanism drives the rotating shaft to rotate so that the time for the butt joint pipe to be opposite to the oil inlet and the oil outlet is shorter than the time for the butt joint pipe to be completely staggered with the oil inlet and the oil outlet, namely the time for the oil inlet and the oil outlet to have large flow is shorter than the time for small flow.
For the washing operation, the washing time ratio of the large flow rate and the small flow rate is actually adjusted according to the length, the diameter, the dirt degree and the like of the pipeline to be washed, for example, the small flow rate is used for washing for five minutes, the large flow rate is used for washing for one minute, the large flow rate is not too short, and the situation that when the pipeline to be washed is long, the turbulent flow effect formed by the large flow rate is not transmitted to the rear part of the pipeline to be washed and disappears is prevented.
Specifically, in order to realize the turbulent effect formed by high-flow and low-flow or high-pressure and low-pressure flushing on the basis of the foregoing embodiment, the output power of the motor can be directly changed, but because the flushing time of a single pipeline to be flushed is long, and the embodiment usually needs to continuously flush a plurality of pipelines to be flushed, the motor generates instantaneous high current when the speed is increased for a long time, which is not favorable for long-time operation of the motor.
Based on this, it is considered to make the following settings for the drive mechanism: the driving mechanism 3 comprises a driving shaft 31, a first partial gear 32, a second partial gear 33, a first driving gear 34 and a second driving gear 35; the first partial gear 32 and the second partial gear 33 are coaxially connected to the rotating shaft; the first driving gear and the second driving gear are coaxially connected to the driving shaft; the first part of gears are provided with two first transmission teeth with 90-degree arc angles at intervals of 90-degree arc angles, and similarly, the second part of gears are provided with two second transmission teeth with 90-degree arc angles at intervals of 90-degree arc angles; therefore, the meshing time of the first transmission gear and the first driving gear is staggered with the meshing time of the second transmission gear and the second driving gear; and the transmission ratio of the first transmission gear to the first driving gear is different from the transmission ratio of the second transmission gear to the second driving gear. The transmission ratio of the first transmission gear to the first driving gear is a first transmission ratio, and the transmission ratio of the first transmission gear to the second driving gear is a second transmission ratio, wherein the first transmission ratio is as follows: the value of the second gear ratio is not less than 5. When the first transmission gear is meshed with the first driving gear, the flow hole is completely staggered with the oil inlet and the oil outlet. An inertia wheel 5 that rotates with the drive shaft is fixed to the drive shaft.
When the embodiment is started, large power is needed to enable the inertia wheel to rotate to store energy (can be started by means of external force) and then keep a certain rotating speed, and when the speed is increased, partial kinetic energy of the inertia wheel is used as supplement of the driving motor, so that long-time operation of the driving motor is facilitated. Because the control accuracy requirement of the washing operation on the operation time is not high, the output power curve of the motor can be optimized based on the control accuracy requirement, and the inertia wheel and the driving motor can compensate each other in different time periods.
In order to reduce the frictional resistance between the adjusting block and the side wall of the shell, the middle parts of the two axial end surfaces of the adjusting block are concave, and the edge of the circumferential side surface of the adjusting block 2 is in contact with the inner wall of the shell.
