[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0030] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0031] In one embodiment of the present invention, Figure 1 A vibration isolation device for an electric pump 100 is shown, comprising:

[0032] The electric pump 100 and the first shock absorber 200 , one end of the first shock absorber 200 is used for hoisting connection with the raft frame 300 ; the other end of the first shock absorber 200 is connected with the electric pump 100 .

[0033] In this embodiment, the vibration isolation device of the electric pump 100 is provided with an electric pump 100 and a first shock absorber 200, wherein one end of the first shock absorber 200 is hoisted on the raft frame 300 of the hull, and the other end of the first shock absorber 200 is connected to the electric pump 100. In this way, the electric pump 100 is hoisted below the raft frame 300, saving a lot of space above the raft frame 300, making the staff pass smoothly, and not easily scratching the equipment, and reasonably utilizing the internal space of the hull. In addition, under the action of the first shock absorber 200, the vibration of the electric pump 100 during operation can be effectively reduced. At the same time, it can be understood that due to the hoisting of the electric pump 100, the electric pump 100 is only in contact with the first shock absorber 200, which greatly reduces the contact area between the electric pump 100 and other equipment, further reduces the transmission of vibration noise, and improves the working environment of the staff and the service life of the equipment. It can be understood that the first shock absorber 200 uses a 6JX-200 shock absorber, which is a rubber metal shock absorber.

[0034] In one embodiment of the present invention, Figure 1 As shown, the first shock absorber 200 includes: a first lifting connector 210 ; the first lifting connector 210 is used to connect one end of the first shock absorber 200 to the raft frame 300 by lifting.

[0035] In this embodiment, the first shock absorber 200 is provided with a first lifting connector 210, and the first lifting connector 210 is used to lift the first shock absorber 200 below the raft frame 300. In this way, the first shock absorber 200 is lifted below the raft frame 300, thereby reducing the vibration of the electric pump 100 and lifting the electric pump 100 below the raft frame 300, thereby saving a lot of space above the raft frame 300, allowing staff to pass smoothly without easily scratching the equipment, and reasonably utilizing the internal space of the hull.

[0036] It can be understood that one end of the first hoisting connector 210 is connected to the raft frame 300 by welding, so that the connection between the first hoisting connector 210 and the raft frame 300 is tightened, thereby improving stability.

[0037] In one embodiment of the present invention, Figure 1 As shown, the first shock absorber 200 further includes a second hanging connector 220 , one end of the second hanging connector 220 is connected to the other end of the first shock absorber 200 , and the second hanging connector 220 is sleeved on the electric pump 100 .

[0038] In this embodiment, the first shock absorber 200 is also provided with a second lifting connector 220. Specifically, one end of the second lifting connector 220 is connected to the other end of the first shock absorber 200, and the second lifting connector 220 is provided with a through hole. The size of the through hole matches the radial size of the electric pump 100, so that the electric pump 100 is mounted on the second lifting connector 220. In this way, the electric pump 100 is lifted below the first shock absorber 200, so that the first shock absorber 200 can reduce the vibration of the electric pump 100 while saving a lot of space above the raft frame 300, so that the staff can pass smoothly without easily scratching the equipment, and the internal space of the hull is reasonably utilized.

[0039] It is understandable that the second lifting connector 220 is fixed to the first shock absorber 200 by means of bolts, which not only facilitates the removal and installation of the electric pump 100 while tightening the connection, but also improves the efficiency of maintenance and replacement of the electric pump 100 .

[0040] In one embodiment, the second lifting connector 220 is welded to the electric pump 100 and is securely connected to improve the lifting stability. It can be understood that the second lifting connector 220 is equivalent to the mounting edge of the electric pump 100, which facilitates the connection of the electric pump 100 to the first shock absorber 200.

[0041] In one embodiment of the present invention, Figure 2 A vibration isolation system of an electric pump 100 is shown, comprising: a raft frame 300 and any one of the above vibration isolation devices of the electric pump 100 ; the vibration isolation device of the electric pump 100 is connected to the raft frame 300 .

[0042] In this embodiment, the vibration isolation system of the electric pump 100 is provided with a raft frame 300 and any one of the above-mentioned vibration isolation devices of the electric pump 100. Any one of the above-mentioned vibration isolation devices of the electric pump 100 is connected to the raft frame 300. Specifically, the vibration isolation device of the electric pump 100 is hoisted under the raft frame 300, which saves a lot of space above the raft frame 300, allowing the staff to pass smoothly without easily scratching the equipment, thereby reasonably utilizing the internal space of the hull.

[0043] In one embodiment of the present invention, Figure 2 As shown, a mounting hole 310 is provided on one side of the raft frame 300 close to the electric pump 100 ; the size of the mounting hole 310 is larger than the radial size of the electric pump 100 , so that the electric pump 100 can extend into the interior of the raft frame 300 .

[0044] In this embodiment, a mounting hole 310 is provided on one side of the raft frame 300 close to the electric pump 100. Specifically, the aperture size of the mounting hole 310 is larger than the radial size of the electric pump 100. With this arrangement, the electric pump 100 can be inserted into the interior of the raft frame 300 while being hoisted under the raft frame 300, thereby saving space under the raft frame 300, reasonably arranging the internal space of the hull, and moving the center of gravity of the vibration isolation system of the electric pump 100 upward, making it more compact and improving the stability of the system.

[0045] It can be understood that extending the electric pump 100 into the interior of the raft frame 300 can greatly shorten the axial dimension of the first lifting connector 210, thereby saving material costs and improving the structural strength of the first lifting connector 210, thereby improving the stability of the system, and the length of the electric pump 100 extending into the interior of the raft frame 300 can be selected according to the size of the selected first shock absorber 200, thereby improving the application range of the system and making the selection range of the first shock absorber 200 wider.

[0046] In one embodiment of the present invention, Figure 2 As shown, the vibration isolation system of the electric pump 100 further includes: a main unit group 400; the electric pump 100 is connected to an interface of the main unit group 400.

[0047] In this embodiment, the vibration isolation system of the electric pump 100 is also provided with a main unit 400. The main unit 400 is the power source of the ship. A large amount of heat is generated when the main unit 400 is working. The electric pump 100 is connected to the interface of the main unit 400 to pump unused coolant into the main unit 400, and the used coolant of the main unit 400 is extracted from the main unit 400, so as to cool the main unit 400 and improve the working stability of the main unit 400.

[0048] It can be understood that when there are multiple electric pumps 100, every two electric pumps 100 can be used as a group, one of the electric pumps 100 in each group is used to pump coolant into the main unit 400, and the other is used to pump coolant out of the main unit 400, and the multiple electric pumps 100 are respectively located on both sides of the main unit 400. While arranging the space reasonably, the center of gravity of the system is placed in the middle position to ensure the stability of the system.

[0049] In one embodiment of the present invention, Figure 2 As shown, the electric pump 100 includes: an inlet pipeline 110 and an outlet pipeline 120, the inlet pipeline 110 is used to be connected to the hull, and the outlet pipeline 120 is connected to the interface.

[0050] In this embodiment, the electric pump 100 is provided with an inlet pipe 110 and an outlet pipe 120, wherein the inlet pipe 110 of the electric pump 100 is used to connect with the hull so as to extract the coolant stored in the hull, and the outlet pipe 120 of the electric pump 100 is connected with the interface of the main unit 400 so as to pump the coolant in the hull into the main unit 400 to cool the main unit 400, and the electric pump 100 pumps the coolant with excessive temperature in the main unit 400 from the outlet pipe 120 to the inlet pipe 110, and then discharges the coolant in the main unit 400 into the hull for cooling, so that the coolant can be recycled.

[0051] In one embodiment of the present invention, Figure 2 As shown, the electric pump 100 further includes: an inlet vibration-damping pipe 130 and an outlet vibration-damping pipe 140 . The inlet vibration-damping pipe 130 is connected to the inlet pipeline 110 , and the outlet vibration-damping pipe 140 is connected to the outlet pipeline 120 .

[0052] In this embodiment, the electric pump 100 is further provided with an inlet vibration-damping pipe 130 and an outlet vibration-damping pipe 140, wherein the inlet vibration-damping pipe 130 is connected to the inlet pipeline 110, and the outlet vibration-damping pipe 140 is connected to the outlet pipeline 120. Such a configuration reduces the vibration acting on the inlet pipeline 110 and the outlet pipeline 120 when the electric pump 100 is working, thereby preventing the vibration from being transmitted to the main unit 400 and affecting the operation of the main unit 400, thereby improving the service life of the main unit 400 and the stability of the system operation.

[0053] It is understandable that the inlet vibration-damping pipe 130 and the outlet vibration-damping pipe 140 can be vibration-damping pipes made of elastic soft materials such as spring vibration-damping pipes or rubber vibration-damping pipes.

[0054] In one embodiment of the present invention, Figure 2 As shown, the vibration isolation system of the electric pump 100 further includes: a second vibration absorber 500 , one end of the second vibration absorber 500 is used to be connected to the hull base 600 , and the other end of the second vibration absorber 500 is connected to the raft frame 300 .

[0055] In this embodiment, the vibration isolation system of the electric pump 100 is further provided with a second vibration absorber 500, which is used to reduce vibration of the raft frame 300. Specifically, the second vibration absorber 500 is arranged on the bases on both sides of the hull, and the raft frame 300 is erected on the second vibration absorber 500 on both sides. In this arrangement, the second vibration absorber 500 supports the raft frame 300 while reducing the vibration of the raft frame 300 itself and the vibration transmitted to the raft frame 300 when the electric pump 100 is working, thereby improving the vibration reduction effect of the system and improving the stability of the system. It can be understood that the second vibration absorber 500 adopts a BE-120 type vibration absorber, which is a rubber metal vibration absorber.

[0056] In one embodiment of the present invention, Figure 2 As shown, the inlet pipeline 110 and the outlet pipeline 120 are both laid on a side of the raft 300 close to the electric pump 100 .

[0057] In this embodiment, the inlet pipeline 110 and the outlet pipeline 120 are both laid on the side of the raft frame 300 close to the electric pump 100. This arrangement allows all pipelines to be laid under the raft frame 300, making the pipeline arrangement convenient and less prone to interference. A large amount of space above the raft frame 300 is saved, allowing staff to pass smoothly and making rational use of the internal space of the hull.
