Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a movable power supply vehicle that can be used for broadcasting, emergency use such as disasters, construction work, and all other uses, and is particularly capable of passing through narrow roads. This is about a small power-powered vehicle that does not take up much parking space.

[Problem that the invention attempts to solve]

For small power supply vehicles, compared to large power supply vehicles, it is difficult to take sufficient sound and vibration prevention measures due to loading space, etc., and if you place emphasis on soundproofing and seal the generator, , the cooling efficiency of the generator's prime mover decreases, affecting the power generation capacity and causing problems in long-term operation.

Furthermore, since a heavy generator is loaded onto a small vehicle, the driving performance of the vehicle is greatly affected, resulting in problems such as the steering wheel becomes difficult to operate and the vehicle lacks stability.

This invention solves these problems, and although it is small as a vehicle, it can operate the generator efficiently, so it has a large power generation capacity, makes less noise, has good driving performance as a car, and improves driver safety. It provides a power supply vehicle with many advantages such as high cost.

[Means for solving problems]

A means for solving the above problem is to install a generator at the rear of a box-type vehicle, and to install a partition between the driver's cabin at the front of the vehicle and the generator, as stated in the claims of the utility model registration. A partitioned heat dissipation chamber is provided, and the heat dissipation chamber is provided with a radiator and a heat dissipation fan for the generator, an intake port is provided at the side of the vehicle in the heat dissipation chamber, and an exhaust port is provided at the top of the vehicle in the heat dissipation chamber. This is a soundproof power supply vehicle that is characterized by:

〔Example〕

Figure 1 is a top view of the power supply vehicle according to the embodiment of the present invention;
The figure is a side view, and Figure 3 is a rear view, in which 1 is a box-type vehicle, 2 is a generator, 3 is a generator room, 4 is a rear bulkhead, 5 is a front bulkhead, 6 is a heat radiation chamber, 7 is the radiator, 8 is the fan, 9 is the intake port, 10 is the exhaust port, 1
1 is a duct, 12 is a silencer, 13 is a blower, 14
15 is a small hole in the partition wall, 15 is a louver, 16 is an exhaust port of a silencer, 17 is a lid, and 18 is a switchboard.

As shown in the figure, the generator 2 is placed at the rear of the box-type vehicle 1 almost on the rear axle, and the generator room 3 that houses the generator 2 is separated from the heat radiation room 6 by a partition wall 4. It is almost sealed.

The floor of the generator room 3 has a vibration-proof and sound-proof structure made of a combination of light metal and rubber, and the partition wall 4 is a sound-proof wall of a sandwich structure made of steel plates with a sound-absorbing material provided inside. The heat radiation chamber 6 is an independent room separated from the driver's cab by a front partition wall 5, and is equipped with a radiator 7 for the generator 2 inside. The radiator 7 is cooled by a fan 8, and the cooling air is taken in from the outside through an intake port 9, passes through the radiator 7 and a duct 11, and is exhausted to the outside from an exhaust port 10 at the top of the vehicle. The exhaust port is provided at the top of the vehicle from the viewpoint of soundproofing effect and heat exhaust efficiency, and when the generator is operated, the lid 17 is opened by a drive device (not shown) and the exhaust port 10 is opened.

In this embodiment, in order to further release the heat generated in the generator room 3, the blower 13 is installed in the hole 14 of the partition wall 4.
The air inside the generator room 3 is sent into the duct 11 through the duct 11. The louver 15 is an opening for intake of cooling air into the generator room 3. 12 is a high-efficiency muffler that effectively muffles the exhaust noise of the prime mover.

Of course, it is also optional to provide the muffler in the heat radiation chamber 6 or outside the vehicle.

[Operations and effects of the invention] According to the above detailed explanation, according to the invention,
The completely separate structure of the generator room and heat radiation room provides extremely high cooling efficiency, allowing the generator to operate at high efficiency without sacrificing soundproofing performance, and the generator is placed at the rear of the vehicle, making it easy to use as a vehicle. It has excellent safety and does not affect steering operation. Furthermore, in the event of a traffic accident, the heat dissipation chamber acts as a buffer zone, reducing the risk of the driver being crushed by the generator.
