BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to emergency drainage at the time of water disaster,
The present invention relates to a drainage pump vehicle used for drainage of civil engineering temporary construction work or water supply and drainage for agriculture.

[0002]

2. Description of the Related Art Conventionally, as a drainage pump vehicle used for emergency drainage in the event of a water disaster, temporary construction work drainage, agricultural water supply / drainage, etc., a crane used for loading and unloading on-board equipment such as pumps. , A plurality of drainage pumps (submersible pumps) and a drainage pump with floats, a private power generator that supplies power to the drive sources (motors) of these drainage pumps, their operation panel, and drainage ports of each drainage pump. The drain hose to be connected, the cavern tire cable that electrically connects the drive source of each drain pump and the operation panel of the private power generator, the main floodlight for night work, the auxiliary floodlight for spot lighting, and power to this auxiliary floodlight. There is something that is equipped with equipment such as a portable power generator. According to this type of drainage pump vehicle, if it reaches the water level of the drainage or water supply / drainage site by self-propelled, after connecting the drainage hose and the connection of the tire cable, the drainage pump is driven by the crane. Water is drained by operating the drain pump by supplying electric power to the drive source of the drain pump by operating the private power generator.

By the way, in the conventional drainage pump vehicle,
If the ground at the drainage or water supply / drainage site and its surroundings is hard, the drainage pump car can be driven to the water's edge, but if the ground is soft, it cannot be driven to the water's edge. Therefore, the stop position of the drainage pump car is restricted to a place relatively remote from the water's edge. For that purpose, various operations such as the work of transporting the drainage pump with a float that has been unloaded from the cargo bed by the crane to the water's edge, the work of laying the drainage pump from the water's edge to the water, and the work of connecting and connecting the cab tire cable are performed manually. There must be. In other words, the work of transporting the drainage pump unloaded from the crane by the crane to the waterside by the hand cart, the construction of the inclined guideboard at the waterside, and the work of laying the drainage pump underwater using the constructed inclined guideboard. Many tasks must be performed by many workers.
Moreover, since these operations are extremely troublesome and difficult, the workability is poor and the quick start of drainage after reaching the drainage or water supply / drainage site is hindered. Further, since a private power generator for operating the drainage pump, a control panel, etc. are required, there is a disadvantage in that the equipment becomes large in size and economically disadvantageous.

Therefore, the applicant of the present invention has filed Japanese Patent Application Laid-Open No. 6-48.
In Japanese Patent No. 238, even when the drainage or water supply / drainage site and the ground around it are soft, the amphibious vehicle is allowed to self-propelled to the water's edge, and the operation of lowering the amphibious vehicle from the carrier bed of the transport vehicle to the water's edge. Operation to move, operation to launch amphibious vehicle from the waterside and move it to the water depth area where the drainage pump can operate in a floating state, operation to stop amphibious vehicle in this water depth and then drain water, after drainage is completed A series of operations such as stopping the operation of the drainage pump, returning the amphibious vehicle to the water's edge, moving it from here to the transportation vehicle and placing it on the cargo bed are all configured by remote control. , Proposed a drainage pump truck that can improve workability.

However, in this type of drainage pump car, the drainage pump car cannot enter the drainage area, for example, when the waterside is formed with a large step or a narrow space.
It has the drawback that it cannot drain water,
There is also a problem that one drainage place is limited to one place, and two drainage places cannot drain simultaneously.

[0006]

The problems to be solved are that water cannot be drained when it is formed on a large step or a narrow space that cannot enter the drainage area.
The number of drainage areas is limited to one, and two drainage areas cannot drain simultaneously.

[0007]
