Technical Field

[0001] The utility model relates to the technical field of generator sets, and particularly relates to a multi - machine parallel generator set. Background Art

[0002] A generator set refers to a power generation device that can convert mechanical energy or other renewable energy into electrical energy. The generator set has a large capacity, can operate in parallel, has a long continuous power supply time, and high reliability. The generator set includes solar generator sets, gasoline generator sets, gas generator sets, diesel generator sets, etc. Among them, the gas - powered generator set is a generator set that meets the environmental protection requirements and the new market environment. In the prior art, as disclosed in patent CN208330539U, there is a box - type gas generator set, which includes a box body and multiple gas generators arranged in the box body. A plurality of air inlets are arranged on the side wall of the box body, and an exhaust port is arranged at one end of the box body. The air inlets are evenly distributed on the box body along the length direction of the box body. A radiator for discharging the air in the box body to the outside of the box body is arranged at the exhaust port. The cold air from the outside enters the box body through the air inlets and then is discharged from the exhaust port. A ventilation and noise reduction section is arranged at the air inlets, and the ventilation and noise reduction section uses a honeycomb ceramic sound absorption board, which can reduce noise. However, the honeycomb ceramic sound absorption board arranged at the air inlets affects the air intake volume and is not conducive to further improving the air intake and cooling effect.

[0030] For the embodiments, see Figures 1-3 :

[0031] A multi-machine parallel type generator set includes a container body 1. The container body 1 includes a central control room 10 and generator rooms 11 on both sides thereof. In the generator rooms 11, power generation units 2 are arranged in parallel along the length direction of the generator rooms 11, and the number of the power generation units 2 arranged in parallel in the generator rooms 11 is two.

[0032] The power generation unit 2 includes a gas power generation device and a water tank heat dissipation device 20 located outside it. An exhaust noise reduction box 3 is arranged on the container body 1 outside the water tank heat dissipation device 20, which is beneficial to improving the space utilization rate. At the same time, the exhaust noise reduction box 3 is used to reduce noise and the impact of noise on the use environment. It can be understood that the inner side of the gas power generation device is the central control room 10, and a ventilation and exhaust channel is arranged on the side wall of the container body 1 between the water tank heat dissipation device 20 and the exhaust noise reduction box 3.

[0033] As an implementation manner, the container body 1 adopts a standard 40HQ container, which meets the standard sea transportation requirements and is convenient for customers to use and turnover.

[0034] The gas power generation device includes a gas engine 21 and a correspondingly connected generator 22. A smoke exhaust pipe 23 is connected to the smoke exhaust port of the gas engine 21, and the smoke exhaust pipe 23 is connected to a smoke exhaust outlet extension pipe 24. A gas valve group is arranged on the air inlet pipeline of the gas engine 21. The smoke exhaust outlet extension pipe 24 is detachably installed on the top of the unit room 11, facilitating the turnover and transportation of the container body 1. The smoke exhaust outlet extension pipe 24 raises the outlet of the smoke exhaust pipe 23, which is beneficial to reducing the impact on the surrounding environment of the container body 1.

[0035] A top air inlet box 4 is detachably installed on the top of the unit room 11. The top air inlet box 4 effectively increases the air volume entering the unit room 11.

Since the gas engine 21 needs air to enter during operation, the top air inlet box 4 serves as the main air inlet channel. Designing this main air inlet channel on the top of the container body 1 can reduce the noise impact on the surroundings. At the same time, the detachable design facilitates the turnover and transportation of the container body 1.

[0038] A parallel control device is arranged in the central control room 10, and each gas power generation device is electrically connected to the parallel control device. The parallel control device includes a parallel control cabinet 5 and a transformer 50. The parallel control cabinet 5 can be used alone or in parallel with multiple units. The output cables and control lines of each gas power generation device are paralleled in the parallel control cabinet 5. After being paralleled, the output cables are connected to the transformer 50 and output to the customer terminal for use after being stepped up by the transformer 50.

[0039] Two unit rooms 11 are paralleled with 4 gas power generation devices in total, effectively meeting the high-power demand. During use, single, double, triple or four gas power generation devices can be selected according to the power demand. When an individual gas power generation device fails internally, the remaining gas power generation devices can still meet the emergency use of customers.

[0040] As an implementation manner, a main combined breaker is arranged in the parallel control cabinet 5, and the main combined breaker adopts a manual and automatic integrated combined breaker.

[0041] As an implementation mode, the water tank heat dissipation device 20 adopts a vertical dual-fan water tank radiator, and the two fans of the vertical dual-fan water tank radiator are respectively located at the upper and lower sides, so as to achieve a better heat dissipation effect.

[0042] As an implementation mode, the central control room 10 is provided with a central control door 12 on both the front and rear sides, and the unit room 11 is provided with a unit door and side air inlet louvers 13 on both the front and rear sides. The side air inlet louvers 13 on both sides serve as auxiliary air inlet, and cooperate with the top air inlet box 4 on the top to achieve a better air inlet effect.

[0045] Preferably, observation windows are provided on the central control door 12 and the unit door to facilitate observation of the operating conditions. The observation windows are made of tempered glass, which ensures that the observation windows have a good service life.

[0046] As an implementation mode, the parallel control cabinet 5 is arranged with a central control door 12 facing the front side, and the transformer 50 is arranged with a central control door 12 facing the rear side, so as to facilitate maintenance and repair.

[0047] As an implementation mode, an operation panel 16, a unit operation indicator light 17 and an emergency stop button 18 are arranged on any central control door 12. The operation panel 16, the unit operation indicator light 17 and the emergency stop button 18 are all electrically connected to the parallel control device, which is convenient for customer operation and also conducive to protecting the safety of use.
