Abstract

PURPOSE:To enhance, the driving efficiency of a discharge water power generation working vehicle, by coupling a power transmission device to the output shaft of a power take-off device so that two output powers are transmitted to a generator and an underwater pump, respectively. CONSTITUTION:Power is taken off from a drive device 2 on a working vehicle by means of a power transmission device 4 having two output shafts 8, 9. The rotary shaft 10a of a generator 10 is coupled with the free end of one output shaft 8 while a connecting plug 9a for a flexible power transmitting cable 11 which is connected to the impeller shaft of an underwater pump P is coupled with the free end of the other output shaft 9. Therefore, there is no need for individually providing drive devices, thereby it is possible to simplify the structure.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a waste water power generation vehicle used mainly for drainage works such as sewerage and civil engineering works.

(Prior art) As a prior art, a drive device and a generator are mounted on a tabletop, the generator is driven by the drive device, and an electric submersible pump driven by the generated 28 g of electric power is connected via an electric crane. A wastewater power generation work vehicle with a structure that pumps up water from below the ground using the submersible pump
No. 4708) has been proposed.

(Problems to be Solved by the Invention) In the prior art, since the generator and its VJ device are mounted on the chassis, the space on the chassis is limited to their Wi-Fi.
It is mostly occupied by Z, making it inconvenient as it is impossible to transport the equipment necessary for drainage work on a vehicle platform.Also, since the pump is driven using electricity generated by a generator, the drive efficiency is poor. It had the disadvantage of a low pumping capacity of 11.

This invention was developed based on the above-mentioned points, and the generator and submersible pump can be driven using the driving device of the working vehicle.The structure is a front vehicle, the installation space is small, and the pump has a high pumping capacity. The aim is to provide a wastewater power generation work vehicle.

(Means for solving the above problems) The configuration of the present invention is to provide a power extraction device for extracting power from a drive device of a working vehicle, connect a power transmission device to the output shaft of the power extraction device, and connect the power transmission device to the output shaft of the power extraction device. The gist is that the rotating shaft of the generator is connected to one output shaft of the transmission device, and a flexible power transmission cable whose tip is connected to the rotating shaft of the ice pump can be connected to the other output shaft. It is something to do.

(Example) Embodiments of the present invention will be described below based on the drawings.

Figure 1 is a perspective view of the wastewater power generation work vehicle in chassis state, Figure 2
The figure is a plan view of the drive system. In these drawings,
Reference numeral 1 denotes an auxiliary power extraction device for extracting power from the drive device 2 of the work vehicle A, and this power extraction device 1 is attached to the transmission 3 of the work vehicle A. Reference numeral 4 denotes an effect transmission device, which includes a drive shaft 5 connected to the output shaft 1a of the power extraction device 1, a speed increasing gear device 6 connected to the drive shaft 5, and a timing belt speed increasing device 7.

Further, the timing held speed increasing device 7 has a large diameter drive pulley 7a which is rejuvenated by the output shaft 6a of the speed increasing gear device 6, and a shaft is passed between the large diameter drive boob 'J7a and the small diameter driven boob 'J7c. It consists of a timing belt 7b and a small diameter driven pulley 7C. Further, the small diameter driven pulley 7C is provided with two output shafts 8.9, one of which is connected to the rotation shaft 10a of the generator 10, and the other output shaft 9 is connected to the rotation shaft 10a of the generator 10.
A connection plug 9a at the proximal end of the flexible assistance transmission cable 11 whose tip end is connected to the impeller rotating shaft of the submersible pump P is attached to the end. The above-mentioned devices are all arranged under the chassis frame or cough frame of the work desk A, as shown in FIG.

(effect) Next, the operation of the embodiment having the above configuration will be explained.

Drive device 2 to the work vehicle is idling! The engine is driven at a slightly higher rotational speed than before, power is extracted from the transmission 3 via the assist extraction device 1, the rotational speed is increased by the two speed increasers 6.7, and the two output shafts 8. 9 (described publicly. In this state, to perform drainage work, connect the connecting plug 9a at the base end of the power transmission cable 11 whose tip is connected to the impeller rotating shaft of the submersible pump P to the output shaft 9.
At the same time, the submersible pump P is lowered into, for example, a culvert under a manhole, and water is drained using a drainage hose H connected to the submersible pump P.

The submersible pump P is of a type in which the impeller is directly driven via the power transmission cable 11, and since the pump P is placed at the drainage location and pumps up water, the pump has a high pumping capacity and can be used quite deep underground. Drainage can be done from any position.

Furthermore, when power is required for lighting, etc. for night work or other purposes, lighting equipment and the like are connected to the power generation 510.

In this way, drainage work is performed while driving the generator 10 and submersible pump P as appropriate.

(Effects of the Invention) As explained above, according to the present invention, the power generator and the submersible pump are driven using the driving device of the working vehicle, so there is no need to install a separate driving device. It is 5 base, requires a small installation space, and the loading platform can be effectively used as a J-bar for equipment for drainage work.
