Description

Technical Field

[0001] This utility model relates to the field of generators, specifically to a marine gas generator set. Background Technology

[0002] Traditional diesel-powered generators, due to their high emissions and fuel costs, are increasingly failing to meet the needs of modern ships. Gas turbine generators, with their advantages of cleaner fuel, lower emissions, and lower operating costs, are finding wider application in the marine industry.

[0003] Existing marine gas turbine generator sets consist of a gas engine, a generator, and a seawater pump for cooling the gas engine. Traditionally, each generator set is installed independently on the ship, occupying considerable space and resulting in a large overall structure, which is unsuitable for installation and layout on ships with limited space. Furthermore, ships face various complex environments during navigation, such as turbulence and rolling. The stability of the generator set components is relatively poor, and they are prone to loosening during turbulence, affecting the normal operation of the generator set. Improvements are needed in these areas. Utility Model Content

[0004] The purpose of this utility model is to provide a marine gas generator set to address the above problems, thereby solving the issues of large space occupation and easy loosening of components and poor stability of existing generator sets when the ship is rocking.

[0005] To achieve the above objectives, this utility model discloses a marine gas generator set, a gas engine and a generator, and also includes a chassis. The gas engine and the generator are mounted on the chassis and are fixedly connected. The generator is poweredly connected to the power output end of the gas engine. A seawater pump is also provided on the chassis. The seawater pump is connected to the cooling system of the gas engine through a pipe. A shock absorber supporting the gas engine and the generator is provided on the chassis.

[0006] The core components, including the gas engine, generator, and seawater pump, are all integrated onto the chassis to form a complete generator set. The generator set features a rational layout and compact structure, occupying minimal space on the ship and facilitating installation and placement. Shock absorbers effectively reduce the impact of ship turbulence on the gas engine and generator control cabinet, improving the overall stability of the generator set, preventing components from loosening or being damaged due to turbulence, ensuring normal operation of the generator set, and extending the lifespan of its components.

[0007] The chassis includes a front plate, with left and right plates at its left and right ends respectively. The left and right plates extend rearward, and a rear plate connects them at their rear ends. The front, rear, left, and right plates together form a rectangular frame structure. This rectangular frame structure provides high mechanical strength and overall rigidity, enabling it to withstand the weight of the generator set itself and various stresses generated by the ship's rolling and tilting, while also facilitating the installation layout of the generator set's components.

[0008] Two shock absorbers are installed at the bottom of the gas turbine engine, mounted on the front and rear plates respectively. Since the gas turbine engine does not directly contact the chassis, the shock absorbers reduce vibrations from the hull. These shock absorbers effectively reduce the impact of ship turbulence on the gas turbine engine, improving the stability of the entire generator set, preventing components from loosening or being damaged due to turbulence, and ensuring the normal operation of the generator set.

[0009] A fixed bracket is installed between the front and rear plates, located below the generator. Two shock absorbers are mounted on the fixed bracket, and their upper parts are connected to the generator. The generator does not directly contact the chassis. The two shock absorbers at the bottom of the generator, together with the shock absorbers at the bottom of the gas engine, form a four-point support, ensuring balance and effectively reducing the impact of ship turbulence on the gas generator set.

[0010] The spacing between the two shock absorbers at the bottom of the gas engine is greater than the spacing between the two shock absorbers at the bottom of the generator. The gas engine is large and the generator is small, and this layout facilitates the installation of the gas engine and the generator.

[0011] A support frame is provided on the front panel, comprising an upwardly extending vertical plate and a forward-extending horizontal plate above the vertical plate. Ribs are installed at the angle between the vertical and horizontal plates, and the seawater pump is mounted on the upper side of the horizontal plate. The support frame is installed on the front side of the chassis and extends forward, without occupying the installation space of the gas engine, and facilitates the disassembly and maintenance of the seawater pump, as well as the pipeline layout, avoiding interference with other components.

[0012] The seawater pump is connected to the output of the gas engine via a belt. A protective cover is installed on the left plate to protect the belt and pulleys. The cover is located on the left side of the belt and pulleys. The cover prevents foreign objects from entering the transmission system, avoids belt slippage, damage or detachment, and extends the service life of the belt and pulleys.

[0013] The front panel is equipped with a support base, on which the control cabinet is mounted. The control cabinet is located on the front side of the generator. The control cabinet is firmly and stably installed, and it is easy for staff to operate the buttons.

[0014] The control cabinet is equipped with a display screen for showing the operating parameters of the gas engine and generator, allowing operators to conveniently monitor all key operating parameters and control the unit operation from one location.

[0015] The control cabinet is electrically connected to the gas engine and is equipped with operating buttons for controlling the gas engine. These buttons provide a manual control option, allowing operators to maintain normal operation of the generator set and improve its reliability in case of automatic control failure. Additionally, the control cabinet includes a remote control module for remote control functionality.

[0016] In summary, the beneficial effects of this utility model are as follows: the generator set has a reasonable layout and compact structure, shortens the power transmission path between the engine and generator, improves transmission efficiency, occupies little space on the ship, reduces the overall footprint of the unit, and facilitates installation and arrangement on the ship. The shock absorber effectively reduces the impact of ship turbulence on the gas engine, improves the stability of the entire generator set, prevents components from loosening or being damaged due to turbulence, ensures the normal operation of the generator set, and extends the lifespan of the generator set's components. The protective cover effectively isolates mechanical damage, protects transmission components, and ensures stable, efficient, and safe operation of the generator set in the ship's environment.

The spacing between the two shock absorbers 11 at the bottom of the gas engine 1 is larger than the spacing between the two shock absorbers 11 at the bottom of the generator 3. The gas engine 1 is large and the generator 3 is small. This layout facilitates the installation of the gas engine 1 and the generator 3.

[0023] See attached document Figure 2A support frame 14 is provided on the front panel 17. The support frame 14 includes an upwardly extending vertical plate 15, and a forward-extending horizontal plate 16 is provided above the vertical plate 15.

A support base 12 is provided on the front plate 17, and a control cabinet 4 is mounted on the support base 12. The control cabinet 4 is located in front of the generator 3, and is securely and stably installed, facilitating button operation by the operator.
