[0002] In existing technologies, power supply vehicles generate significant noise during power supply protection operations, which can disrupt residents' lives to varying degrees. Therefore, designing a low-noise power supply protection vehicle has been a long-standing goal for power industry workers, one that not only ensures power supply but also minimizes noise pollution during the operation. Utility Model Content

[0003] The purpose of this utility model is to provide a low-noise power supply vehicle to solve the technical problems existing in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A low-noise power supply vehicle includes a chassis and a carriage mounted on the chassis. The inner wall of the carriage is equipped with a double-layer noise reduction structure. The interior of the carriage is divided into three functional areas by a front partition and a rear partition. The three functional areas, from the front to the rear of the vehicle, are an exhaust chamber, a generator room, and a medium-voltage cabinet room. The exhaust chamber houses the generator set's fuel tank, and the generator set is housed in the generator room. The generator set's exhaust port is located near the exhaust chamber, and its air inlet is located near the medium-voltage cabinet room. The medium-voltage cabinet room houses the medium-voltage cabinet and a cable reel. The top of the exhaust chamber is equipped with exhaust louvers for discharging the exhaust gas generated by the generator set. Two air inlet louvers are located on the left and right sides of the generator room for supplying fresh air from outside the carriage into the carriage.

[0005] Furthermore, a noise reduction device is provided on the inner side of the air intake louver. The noise reduction device includes a rectangular frame and several noise reduction sheets disposed within the rectangular frame. The noise reduction sheets are made of a noise reduction perforated plate and have sound-absorbing cotton attached to their inner side.

[0006] Furthermore, the double-layer noise reduction structure consists of a foam material layer and a rock wool board layer. One side of the foam material layer is adhered to the inner wall of the carriage, and the other side is adhered to the rock wool board layer. The foam material layer is made of polyurethane foam.

[0007] Furthermore, both the front and rear partitions are made of double-layer rock wool boards.

[0008] Furthermore, the front partition is provided with an air outlet, which is directly opposite the exhaust port of the generator set. The exhaust port of the generator set is located at the front end of the generator set, and the air inlet of the generator set is located at the rear end of the generator set, close to the two air inlet louvers.

[0009] Furthermore, a canopy is also provided in the exhaust chamber, and the canopy is placed outside the generator set fuel tank to cover the generator set fuel tank.

[0010] Furthermore, a silencer is installed on the top of the unit room.

[0011] Furthermore, two first inspection doors are provided on the left and right sides of the exhaust chamber.

[0012] Furthermore, the unit room is equipped with two first doors and two second maintenance doors on the left and right sides respectively.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: It employs multiple noise reduction measures, significantly reducing the noise generated during the operation of the power supply vehicle. Specifically, the first level of noise reduction involves installing a noise reduction device inside the air intake louvers to reduce noise generated by the opening of the air intake louvers 14. The second level of noise reduction utilizes a double-layer noise reduction structure along the entire inner wall of the vehicle to reduce most of the noise generated by the generator set during operation. The third level of noise reduction further reduces the noise of the generator set's exhaust gas by designing the exhaust outlet of the power supply vehicle at the top of the vehicle, away from the noise source. Compared to ordinary noise reduction methods, the noise reduction effect is significant; noise tests show that its noise reduction effect is 5 decibels greater than that of ordinary noise reduction methods.

[0021] The present invention will be further described below with reference to the accompanying drawings: See Figures 1 to 5 This utility model provides a low-noise power supply vehicle, including a chassis 1 and a carriage 2 mounted on the chassis 1. The inner wall of the carriage 2 is provided with a double-layer noise reduction structure, which can reduce most of the noise of the generator set 2. The inner cavity of the carriage 2 is divided into three functional areas by a front partition 3 and a rear partition 4. The three functional areas are, from the front to the rear of the vehicle, an exhaust chamber 5, a generator room 6, and a medium-voltage cabinet room 7. The exhaust chamber 5 is equipped with a generator set oil tank 8. The generator set 10 is equipped with a generator set 6. The exhaust port of the generator set 10 is close to the exhaust chamber 5, and the air inlet is close to the medium-voltage cabinet room 7. The medium-voltage cabinet room 7 is equipped with a medium-voltage cabinet 11 and a cable reel 12. The top of the exhaust chamber 5 is equipped with an exhaust louver 13 for discharging the exhaust gas generated by the generator set 10. The generator room 6 is equipped with two air inlet louvers 14 on the left and right sides for delivering fresh air from outside the carriage 2 into the carriage 2 (i.e., the generator room 6). When the generator set 10 is working, the exhaust louver 13 and the air intake louver 14 open automatically. The air intake louver 14 first draws fresh air from outside the carriage 2 into the generator room 6, where it mixes and burns with the fuel inside the generator set 10. When the generator set 10 is working, the high-temperature exhaust gas generated by the combustion of fuel inside is then discharged through the exhaust louver 13.

[0022] Specifically, as a preferred embodiment of this utility model, see [reference needed]. Figures 5 to 7 A noise reduction device 15 is installed inside the air intake louver 14, which ensures that fresh air from outside enters the unit room 6 while reducing the noise caused by the opening of the air intake louver 14. More specifically, the noise reduction device 15 includes a rectangular frame 1501 and a plurality of noise reduction plates 1502 disposed within the rectangular frame 1501. The noise reduction plates 1502 are made of noise reduction perforated plates and have sound-absorbing cotton 1503 attached to their inner sides.

[0023] Specifically, as a preferred embodiment of this utility model, the double-layer noise reduction structure consists of a foam material layer and a rock wool board layer, wherein one side of the foam material layer is adhered to the inner wall of the carriage 2, and the other side is adhered to the rock wool board layer. More specifically, the foam material layer is preferably made of polyurethane foam.

[0024] Specifically, as a preferred embodiment of this utility model, both the front partition 3 and the rear partition 4 are made of double-layer rock wool boards, that is, they are composed of two layers of rock wool boards, which can reduce the noise of the generator set 10.

[0025] Specifically, the front partition 3 is provided with an air outlet, which is directly opposite the exhaust port of the generator set 10. The exhaust port of the generator set 10 is located at the front end of the generator set 10, and the air inlet of the generator set 10 is located at the rear end of the generator set 10 and close to the two air inlet louvers 14.

[0026] Specifically, as a preferred embodiment of the present invention, a canopy 9 is also provided inside the exhaust chamber 5, and the canopy 9 is installed outside the generator set fuel tank 8 to cover the generator set fuel tank 8 and prevent external rainwater from entering the generator set fuel tank 8. The generator set fuel tank 8 is used to provide the generator set 10 with the fuel (such as diesel) required for operation.

[0027] Specifically, in a preferred embodiment of this utility model, a silencer 16 is provided on the top of the generator room 6, and the silencer 16 is provided with multi-stage silencing plates to reduce the noise generated when the generator set 10 discharges exhaust gas. Since the exhaust gas discharged from the generator set 10 is noisy, the exhaust gas is discharged after being silenced by the multi-stage silencer 16, which can greatly reduce the impact of noise on the surrounding environment.

[0028] Specifically, as a preferred embodiment of this utility model, two first inspection doors 17 are provided on the left and right sides of the exhaust chamber 5 to facilitate staff to refuel the generator set fuel tank 8.

[0029] Specifically, as a preferred embodiment of this utility model, the unit room 6 is provided with two first doors 18 and two second maintenance doors 19 on the left and right sides respectively. The first doors 18 facilitate the entry and exit of staff in the unit room 6, while the second maintenance doors 19 facilitate the operation of the control panel 21 (i.e., human-machine interface) located in the unit room 6. The control panel 21 integrates multiple functions such as monitoring, control, and protection to ensure the safe, stable, and efficient operation of the entire power vehicle. The generator set fuel tank 8 supplies fuel to the generator set 10, which generates electrical energy. The medium-voltage cabinet 11 receives and distributes the electrical energy generated by the generator set 10. The medium-voltage cabinet 11 includes a generator incoming line cabinet, a PT cabinet, a load output cabinet, and a mains incoming line cabinet. The generator incoming line cabinet receives the high-voltage electrical energy from the generator set 10 and protects the lines and equipment from overload, short circuit, and other faults. The PT cabinet converts the high-voltage voltage to low-voltage voltage for use by protection devices, measuring instruments, and other low-voltage equipment. The load output cabinet connects and disconnects the load to meet the power supply needs of different types of equipment and ensures that the output voltage meets the standard requirements. The mains incoming line cabinet draws power from the external power grid and distributes the electrical energy.

[0030] Specifically, as a preferred embodiment of this utility model, the medium-voltage cabinet 7 is provided with two second doors 20 on the left and right sides, which facilitates the staff to enter the medium-voltage cabinet 7, operate or repair the medium-voltage cabinet 11, and retrieve and place cables.

[0031] Finally, it should be noted that the above description is only an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
