[0002] In order to ensure that the heat and radiant heat of the generator set installed in the cabin can be effectively discharged outside the cabin, and sufficient fresh air can enter the cabin, the existing square cabin power stations and automobile power stations need to open air inlets and exhaust vents near the generator set, as well as strong exhaust vents for radiant heat.

[0026] The technical solution of the present invention is further described below in conjunction with specific implementation methods.

[0027] The present invention provides a closed square cabin power station.

[0028] like Figure 1-2As shown, the closed square cabin power station adopts a rectangular cabin 1, and the cabin 1 is laterally separated into a smoke exhaust and silencer room 102, a generator set room 101 and an electrical control room 103 in sequence by partition walls 11.

[0029] The cabin 1 is made of a cabin frame made of welded steel sections by riveting an outer skin, and sound-absorbing rock wool is laid inside the outer skin to reduce noise.

[0030] The partition wall 11 separating the cabins is a skeleton-skinned partition wall, which is made by fixing a double-layer skin on a rectangular frame of the partition wall and filling the space between the two layers with sound-absorbing rock wool.

[0031] The side walls of the smoke exhaust and silencing room 102 and the electrical control room 103 are provided with normally open shutters 14 for heat dissipation. As required, normally open shutters 14 can also be provided on multiple side walls, but space for the inspection door still needs to be reserved.

[0032] The generator room 101 is located in the middle of the closed square cabin power station, and a maintenance door 15 is provided on the side wall for the maintenance and repair of the generator set. The door is closed during operation to seal the noise generated by the generator set in the generator room.

[0033] The generator set includes a generator 3 and an engine 2 , both of which are installed in the generator set room 101 .

[0034] For the purpose of reducing noise, the generator 3 and the engine 2 are both water-cooled. The cooling circulation pipeline of the generator 3 is connected to the generator radiator 4, and the cooling circulation pipeline of the engine 2 is connected to the engine radiator 5. The generator radiator 4 is installed in the smoke exhaust and silencer room 102, and the engine radiator 5 is installed in the electrical control room 103. The cooling circulation pipeline of the generator 3 and the cooling circulation pipeline of the engine 2 are both provided with pumps for circulating the coolant.

[0035] In order to further enhance the heat dissipation effect of the generator radiator 4 and the engine radiator 5 , fans are also installed on the generator radiator 4 and the engine radiator 5 .

[0036] In order to further reduce noise, the present invention further improves the structure of the air intake of the engine 2.

[0037] Please refer to Figure 4 The top of the generator room 101 is constructed with an independent soundproof cavity 12, the bottom of the soundproof cavity 12 is constructed with a through hole, the through hole is connected to the air filter inlet of the engine 2, and the side wall of the soundproof cavity 12 is also constructed with an air inlet 13 connected to the outside. Through this structure, while ensuring the intake volume required for the operation of the engine 2, the sound insulation effect of the generator room is further enhanced by adding the soundproof cavity 12.

[0038] Please refer to Figure 3 In actual application, simply using water cooling will still cause the engine 2 and generator 3 in the closed generator set room 101 to overheat. Therefore, further, a heat exchange radiator 6 is installed in the generator set room 101. As a more preferred solution, the heat exchange radiator 6 is installed in the space between the upper part of the generator and the top of the generator set room, and the coolant circulation pipeline of the heat exchange radiator 6 is connected to the generator radiator 4. By connecting the circulation pipeline to the generator radiator 4, low-temperature coolant can be continuously provided to the heat exchange radiator 6, and then the cold air cooled by the heat exchange radiator is blown to the generator through the fan on the heat exchange radiator 6 to neutralize the radiant heat generated by the generator and the engine, thereby controlling the temperature in the cabin.

[0039] The above-mentioned enclosed shelter power station and the conventional shelter power station of the same specifications were selected for the test related to the operation noise. The results are as follows:

[0040] Shelter form Average weighted noise on both sides of the generator room Conventional Shelter Power Station 85dB(A) Closed Cabin Power Station 76.5dB(A)

[0041] It can be seen from the above results that the noise of the closed square cabin power station on both sides of the generator set room in the present invention is much lower than that of the existing conventional square cabin power station, achieving a better silent effect.

[0042] The closed square cabin power station of the present invention adopts a closed cabin structure, which can more effectively control the noise of the power station. At the same time, the cabin is simple to manufacture, which is more convenient for later repair and maintenance, and further reduces the production and use costs.

[0043] The invention concept is described in detail using specific examples herein, and the description of the above embodiments is only used to help understand the core idea of ​​the invention. It should be pointed out that any obvious modification, equivalent substitution or other improvement made by a person of ordinary skill in the art without departing from the invention concept should be included in the protection scope of the present invention.
