[Industrial applications]

 The present invention relates to a drainage method using a drainage pump vehicle used for emergency drainage in the event of a water disaster, drainage for civil engineering temporary construction work, or water supply / drainage for agriculture.

[0002]

[Prior art]

 Conventionally, as a drainage pump car used for emergency drainage in the event of a water disaster, drainage for temporary construction work, or water supply / drainage for agriculture, cranes used to load and unload equipment such as pumps on trucks, multiple drainage pumps (Submersible pumps) and drainage pumps with floats, private generators that supply power to the drive sources (motors) for these drainage pumps and their operation panels, drainage hoses connected to the drainage outlets of each drainage pump, and each drainage pump. For example, a car tire cable that electrically connects the drive source to the operation panel of the private power generator, a main floodlight for night work, an auxiliary floodlight for spot lighting, and a portable power generator that supplies power to this auxiliary floodlight. Some are equipped with equipment. According to this type of drainage pump car, if it reaches the water level of the drainage or water supply / drainage site by self-propelled, after connecting the drain hose and the cable of the tire cable, the drain pump is put into the water by the crane. Water will be drained by installing it, supplying power to the drive source of the drainage pump by operating the private power generator, and operating the drainage pump.

By the way, in the conventional drainage pump car, when the drainage or water supply / drainage site and the ground around it are hard, the drainage pump car can be self-propelled to the edge of the water, but the ground is soft. It cannot be self-propelled 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 this purpose, it is necessary to manually carry out the work of transporting the drainage pump with a float that has been unloaded from the platform by a 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 cable cable. In other words, the work of transporting the drainage pump that was unloaded from the platform by the crane to the waterside by the hand cart, the construction of the inclined guideway at the waterside, the work of laying the drainage pump in the water using the constructed inclined guideway, etc. Many tasks must be performed by many workers. Moreover, since these operations are extremely troublesome and difficult, the workability is poor and the rapid start of drainage after reaching the drainage or water supply / drainage site is hindered. In addition, since it requires a private power generator for operating the drainage pump and a control panel, it has a disadvantage in that the equipment is large and economically disadvantageous.

Therefore, in the Japanese Patent Application No. 4-33269, the applicant of the present invention allows an amphibious vehicle to self-propell and transport to the water's edge even if the drainage or water supply / drainage site and the ground around it are soft. The operation of lowering the amphibious vehicle from the platform of the vehicle, the operation of moving it from the lowered position to the waterside, the operation of launching the amphibious vehicle from the waterside and moving it to the water depth area where the drainage pump can operate. Stopping the amphibious vehicle in the water depth and then draining it, stopping the operation of the drainage pump after the drainage is completed, returning the amphibious vehicle to the water's edge, and moving it from here to the transport vehicle We proposed a drainage pump vehicle that can be configured to perform a series of operations, such as the operation to mount it on a remote, by remote control and improve workability.

However, in this type of drainage pump vehicle, as shown in FIGS. 3 and 4, the vertical axis EC of the engine 4 is set on the vertical axis BC of the boat-shaped hermetically sealed body 2 so as to have a vertically arranged engine structure. In addition, the intake duct 4A is installed in the front part of the engine 4. Therefore, the dimension of the boat-shaped hermetically sealed body 2 in the front-rear direction, that is, the dimension L1 of the amphibious vehicle 1 in the longitudinal axis E C direction becomes large, and the structure becomes large and heavy. Therefore, in the case of a drainage pump vehicle with a large drainage capacity, the load capacity of a general transport truck will be exceeded, and there is the drawback that the transport to the drainage site must be entrusted to a large special vehicle such as a trailer. Further, the volume and buoyancy of the boat-shaped hermetically sealed body 2 are increased because the dimension of the boat-shaped hermetically sealed body 2 in the vertical axis EC direction is larger than the weight of the load such as the engine 4 and the drainage pumps 5A and 5B. There is also a drawback that the draft level becomes shallow and the floating stability of the amphibious vehicle 1 is slightly reduced.

[0006]

[Problems to be solved by the device]

 The problems to be solved are that the large and heavy structure limits transportation means and that the amphibious vehicle has low levitation stability.

[0007]

[Means for Solving the Problems]

 The present invention provides a self-propelled engine and a drainage pump for draining the water outside the boat-shaped sealed body in an amphibious vehicle capable of running on soft ground with a boat-shaped sealed body. In a drainage pump vehicle configured to drive an amphibious vehicle and a drainage pump by driving the vehicle, the vertical axis of the engine is installed so as to intersect the vertical axis of the amphibious vehicle, and the intake duct of the engine is installed. Is installed at the corner of an amphibious vehicle, and the objective of improving the floating stability of the amphibious vehicle is achieved by reducing the size and weight of the amphibious vehicle to alleviate restrictions on transportation means.

[0008]

[Action]

 According to the present invention, the longitudinal dimension of the amphibious vehicle is reduced by installing the engine so that the longitudinal axis of the engine intersects with the longitudinal axis of the amphibious vehicle, that is, the longitudinal dimension of the amphibious vehicle. Therefore, it is possible to realize the reduction in size and weight corresponding to the size reduction. In addition, compared with the weight of the mounted components such as the engine and drainage pump, the volume and buoyancy of the boat-shaped hermetically sealed body are reduced by the amount of reduction in the longitudinal dimension of the boat-shaped hermetically sealed body, and the draft level is deepened. The floating stability of amphibious vehicles is improved.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic side view showing an example of a drainage pump vehicle to which the present invention is applied, and FIG. 2 is a plan view of FIG. 1. In these figures, 1 is an amphibious vehicle, which is a boat-shaped sealed body 2 and It is composed of a crawler vehicle equipped with a pair of left and right crawlers 3A, 3B capable of traveling on soft ground. The boat-type closed body 2 has an engine 4, two drainage pumps 5A, 5B, and an engine 4. Two hydraulic pumps 6A and 6B to be operated and a hydraulic circuit (not shown) using these hydraulic pumps 6A and 6B as a drive source are mounted in a watertight manner. The suction ports of the drainage pumps 5A and 5B pass through the bottom of the boat-shaped hermetically sealed body 2 and open at the lower side of the bottom. The hydraulic pumps 6A and 6B are directly connected to the engine 4, and these are variable displacement bidirectional flows, and the oil flow direction and the discharged oil amount are adjusted by a regulator. The hydraulic circuit consists of two circuits, one set of hydraulic circuits for vehicle operation, which constitutes the power transmission system for vehicle operation of the amphibious vehicle 1, and one set of two circuits, which constitutes the power transmission system for drainage pump operation. It is equipped with a hydraulic circuit, and switching between the hydraulic circuit for vehicle operation and the hydraulic circuit for drainage pump operation is performed by switching operation of an electromagnetic or electric switching valve. As with the above-mentioned Japanese Patent Application No. 4-33269, a transmitter and a radio signal transmitted from this transmitter are used to control the start / stop and rotation speed, and control the oil flow direction and discharge amount of the hydraulic pumps 6A and 6B. It is designed to be remotely controlled by a control device which is composed of a reception controller which receives and outputs a control signal.

On the other hand, the engine 4 is mounted so that its vertical axis EC crosses the vertical axis BC of the amphibious vehicle 1 and the boat-type closed body 2 at an angle, and the intake duct 4 A is mounted on the amphibious vehicle 1 at the front angle. It is installed in the department. In the figure, 7 is a control panel, 8 is a fuel tank, and 9 is a hydraulic oil tank.

As described above, the longitudinal axis EC of the engine 4 is diagonally crossed with the vertical axis BC of the amphibious vehicle 1 and the boat-type hermetically-sealed body 2 so that the longitudinal dimension of the boat-shaped hermetically-sealed body 2 is That is, the dimension L of the amphibious vehicle 1 in the vertical axis BC direction can be made smaller than the dimension L1 of the amphibious vehicle 1 in the vertical axis BC direction described with reference to FIGS. 3 and 4, and the dimension L is reduced. At the front corner of the amphibious vehicle 1, the intake duct 4A can have a large volume. Therefore, the size and weight of the amphibious vehicle 1 can be reduced corresponding to the reduced size L1-L. As a result, the weight of the vehicle body can be kept within the loading weight of the truck for general transportation, and it is not necessary to use a large special vehicle such as a trailer for transportation to the drainage site.

On the other hand, although the weight of the components such as the engine 4, the drainage pumps 5A and 5B, the hydraulic pumps 6A and 6B, the control panel 7, the fuel tank 8, the hydraulic oil tank 9 and the hydraulic circuit (not shown) does not change, Since the volume and buoyancy of the boat-shaped hermetically sealed body 2 are reduced by the reduction in the longitudinal dimension of the boat-shaped hermetically sealed body 2, and the draft level is deepened, the floating stability of the amphibious vehicle 1 can be improved. .

[0013]

[Effect of device]

 As described above, according to the present invention, the vertical dimension of the amphibious vehicle can be reduced by mounting the engine so that the vertical axis of the engine intersects with the vertical axis of the amphibious vehicle. Can be made smaller and lighter. As a result, the weight of the vehicle body can be kept within the loading weight of the truck for general transportation, and it is not necessary to use a large special vehicle such as a trailer for transportation to the drainage site. In addition, compared to the weight of the stationary components such as the engine and drainage pump, the volume and buoyancy of the boat-shaped hermetically sealed body are reduced by the reduction in the front-back dimension of the boat-shaped hermetically sealed body. Since it becomes deeper, the floating stability of the amphibious vehicle can be improved.
