Description

Technical Field

[0001] The present invention relates to the technical field of box-type diesel generator sets, and particularly relates to a pull-out type fully water-cooled low-noise power station system. Background Art

[0002] The existing heat dissipation methods of box-type generator sets usually include air-cooled, water-cooled, and air-cooled + water-cooled.

[0003] The prior art CN109578136A discloses a fully sealed water-cooled silent generator set, and the prior art CN210343454U discloses a split water-cooled exhaust noise reduction system for a diesel power station. However, the existing box-type generator sets still have problems such as inconvenient maintenance, high noise, and high heat generation. Summary of the Invention

[0004] The object of the present invention is to overcome the deficiencies in the prior art, and provide a pull-out type fully water-cooled low-noise power station system. By adopting a fully water-cooled heat dissipation device, the overall volume of the power station can be greatly reduced, the heat generation / heat temperature in the noise reduction compartment can be reduced, and the pull-out function of the power station can be realized by using heavy-duty guide rails, so that the power station system is more suitable for narrow spaces and is convenient for maintenance. Through the design of concave-convex parts and arc-shaped diversion parts, the turbulence and backflow on both sides of the connecting outer ring can be effectively reduced, thereby reducing the noise of the cooling fan and increasing the air volume.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A pull-out type fully water-cooled low-noise power station system, which includes a noise reduction compartment (1), an output unit (2), a common chassis (3), heavy-duty guide rails (4), a water-cooled engine (5), a control door / maintenance door (6), a water-cooled permanent magnet generator (7), a fuel tank (8), a ventilation waveguide window (9), a water-cooled silencer (10), a filter (11), a water-cooled inverter power supply (12), a control unit (13), a split radiator (14), a cooling fan (15), a water pump (16), a coolant circulation pipe (17), and a split battery (18). It is characterized in that: a common chassis is arranged at the bottom of the noise reduction compartment, and a water-cooled engine, a water-cooled permanent magnet generator, a fuel tank, a water-cooled silencer, a filter, and a water-cooled inverter power supply are installed in the noise reduction compartment and on the common chassis. An output unit, heavy-duty guide rails, a ventilation waveguide window, and a pipe joint are arranged on one side of the common chassis. A control door and / or a maintenance door, a heat dissipation window or a ventilation window are arranged on the side wall of the noise reduction compartment. A split radiator is arranged outside the noise reduction compartment. A cooling fan and a water pump are installed on the split radiator. The split radiator is connected to the pipe joint on the common chassis through multiple groups of coolant circulation pipes. The split battery is arranged beside one side of the split radiator.

[0007] Furthermore, the split-type radiator water tank (14) is connected to each component that needs to be cooled through multiple groups of coolant circulation pipes (17). By adopting a fully water-cooled heat dissipation device, the overall volume of the power station can be greatly reduced, and the heat generation / heat temperature inside the noise reduction compartment can be lowered. Heavy-duty rails (4) are provided on both sides of the common chassis (3). By using the heavy-duty rails, the power station can be made retractable, making the power station system more suitable for narrow spaces and facilitating maintenance.

[0008] Furthermore, the cooling fan (15) includes a shroud and an impeller. The shroud is a fixed part, and the impeller is a rotating part. The impeller is installed inside the shroud. The impeller includes a rotating shaft (151), a hub (152), blades (153), and a connecting outer ring (154). A plurality of blades distributed circumferentially are provided on the outer peripheral surface of the hub. The outer peripheral edges of the blades are connected to the connecting outer ring. The center of the hub is connected to the rotating shaft, and the rotating shaft rotates under the drive of the motor. An uneven part (155) is provided on the upstream end surface of the connecting outer ring (154). The concave-convex-concave-convex structure is distributed along the entire circumference of the connecting outer ring. The extending direction of the concave or convex structure is radial. The concave-convex-concave-convex structure is in a wavy structure along the circumferential direction, and the top and bottom of the concave-convex structure are both in a wavy arc transition.

[0009] Furthermore, an arc-shaped guiding part (156) is provided on the downstream end surface of the connecting outer ring (154). The extending range of the arc-shaped guiding part is across substantially all of the downstream end surface of the connecting outer ring and a small part of the outer peripheral surface of the connecting outer ring.

[0010] Furthermore, an inclined part (157) is provided at the bottom of the concave structure. The inclined part inclines towards the arc-shaped guiding part (156), so that the axial depth of the concave structure gradually increases from the radially inner side to the radially outer side.

[0011] The retractable fully water-cooled low-noise power station system of the present invention has the following beneficial technical effects:

[0012] (1) The split-type radiator water tank is connected to each component that needs to be cooled through multiple groups of coolant circulation pipes. By adopting a fully water-cooled heat dissipation device, the overall volume of the power station can be greatly reduced, and the heat generation / heat temperature inside the noise reduction compartment can be lowered. Heavy-duty rails are provided on both sides of the common chassis.

It is characterized in that: a common chassis 3 is provided at the bottom of the noise reduction box body 1, and a water-cooled engine 5, a water-cooled permanent magnet generator 7, a fuel tank 8, a water-cooled muffler 10, a filter 11, and a water-cooled inverter power supply 12 are installed in the noise reduction box body 1 and on the common chassis 3.

The split-type radiator tank 14 is connected to the pipe joints on the common chassis 3 through multiple groups of coolant circulation pipes 17. The split-type battery 18 is arranged beside one side of the split-type radiator tank 14.

[0023] The split-type radiator tank 14 is connected to each component that needs to be cooled through multiple groups of coolant circulation pipes 17. By adopting a fully water-cooled heat dissipation device, the overall volume of the power station can be greatly reduced, and the heat generation quantity / heat generation temperature inside the noise reduction box body 1 can be lowered.

[0024] Heavy-duty guide rails 4 are provided on both sides of the common chassis 3. By using the heavy-duty guide rails 4, the pull-out function of the power station can be realized, making the power station system more suitable for narrow spaces and convenient for maintenance.

[0025] As Figures 4-5 shown, the cooling fan 15 includes a guard and an impeller. The guard is a fixed part, and the impeller is a rotating part. The impeller is installed inside the guard. The impeller includes a rotating shaft 151, a hub 152, blades 153, and a connecting outer ring 154. A plurality of blades 153 distributed circumferentially are provided on the outer peripheral surface of the hub 152.

[0027] Through the design of the concave-convex portion 155 and / or the arc-shaped flow guiding portion 156, the present invention can effectively reduce the turbulence and backflow on both sides of the connecting outer ring 154, thereby reducing the noise of the cooling fan and increasing the air volume.

[0028] Further, an inclined portion 157 is provided at the bottom of the concave structure, and the inclined portion 157 inclines towards the arc-shaped flow guiding portion 156, so that the (axial) depth of the concave structure gradually increases from the radially inner side to the radially outer side.

[0029] Through the design of the inclined portion 157, the present invention can further reduce the turbulence and backflow on both sides of the connecting outer ring 154, thereby reducing the noise of the cooling fan and increasing the air volume.
