Problems solved by technology

Although its advantages are obvious, it is restricted by power supply conditions, and it cannot be widely used when working in some environments such as the field and desert because it is difficult to find a suitable power supply.
At present, there are mobile engineering power supply vehicles powered by fuel generators, but they are large in size and have exhaust pollution.
There are also battery-powered vehicles used as emergency power sources during disasters. Although they have no exhaust emissions, they are bulky, poor in mobility, high in cost, and narrow in use.

Embodiment 1

[0030] Embodiment one: if figure 1 As shown, the engineering power supply vehicle moves through external equipment traction drive, including: a movable vehicle body 1, on which a power generating device, a power conversion device 3 and a cable retracting device 4 are installed. In this embodiment, The power generating device is a storage battery 2, and a charger 7 is installed at the same time. When necessary, an external power source 8 can be used to charge the storage battery 2. The power conversion device 3 adjusts the power generated by the storage battery 2 and transmits it to the external power supply through the cable retracting device 4. Equipment, the cable retracting device 4 automatically retracts the cable 4.1 through the reel 4.2, the cable retracting device 4 is placed flat on the top of the engineering power supply vehicle, and the rotation axis of the reel 4.2 in the cable retracting device 4 is perpendicular to the horizontal plane of the engineering power supp...

Embodiment 2

[0046] Embodiment two: if figure 2 As shown, the difference with Embodiment 1 is that the movement of the engineering power supply vehicle is independently driven by the electric power generated by the power generating device, that is, the storage battery 2. Specifically, the vehicle body 1 of the engineering power supply vehicle is an electric vehicle 9, and the electric power of its motor 9.1 From the power conversion device 3 on the power supply vehicle, when the electric vehicle 9 is operated to move, the control device 9.3 can send instructions through the signal transceiver device 9.2 on the electric vehicle 9, and after the signal receiving transmitter 5 of the power supply vehicle receives it, the power supply vehicle's The power conversion device 3 provides electric power of the frequency required by the electric vehicle 9 to drive the electric vehicle 9 to move. However, in the system, the power supply of the electric vehicle 9 and the power supply to the external e...

Embodiment 3

[0047] Embodiment 3: In Embodiment 1 and Embodiment 2, the signal connection mode between the power supply vehicle and the electric vehicle is not emphasized, and it can be connected by wired or wireless communication. But in fact, because the cable retractable device 4 is needed to retract the cable 4.1 between the two vehicles, if an additional signal transmission line is added, the retraction of the cable 4.1 will be very difficult. There are two feasible methods. One is to add a set of signal lines in the middle of the 4.1 line of the power transmission cable, and convert the signals to be transmitted on both sides into digital signal strings, which are transmitted interactively. Instructions for controlling different devices. For example, after the speed regulation signal of the operator on the excavator is transmitted to the power supply vehicle, it is sent to the inverter to change the set value of the output frequency of the inverter. The cable 4.1 length deficiency a...

Abstract

An engineering power supply vehicle is used for supplying power to external electric equipment, particularly engineering machines, agricultural machines and the like for field work. The engineering power supply vehicle comprises a movable vehicle body, a signal receiver and transmitter and a controller. The vehicle body is provided with a power generation device, a power conversion device and a cable winding and unwinding device. The power conversion device adjusts power generated by the power generation device, the power is transmitted to the external electric equipment through the cable winding and unwinding device, and the cable winding and unwinding device winds and unwinds cables through a coiling block. The signal receiver and transmitter receives instructions of the external electric equipment, and the controller controls the power conversion device according to the instruction to outputs power required by the external electric equipment. The engineering power supply vehicle can automatically adjust the length of cables so that the external electric equipment can work in a certain stroke range, work rotation capacity is good, environment adaptability is high, and the advantages are more obvious in work zones where oil gas lacks or limitation on noise pollution and waste gas exhaust pollution is strict.

Description

technical field [0001] The invention belongs to the technical field of construction machinery equipment, and relates to construction machinery technology, communication technology and control technology. Specifically, it is an engineering power supply vehicle that can provide electricity for construction machinery and equipment working within a certain range. Background technique [0002] At this stage, most construction machinery and agricultural machinery are driven by fuel engines, which have the advantages of strong mobility and high off-road performance. But at the same time, it has the defects of high engine noise, serious exhaust pollution, high use cost and high maintenance cost. With the country advocating the use of clean energy and the development of machinery-related technologies, construction machinery equipment using electricity as a power source has gradually become a development trend. [0003] Electric construction machinery such as electric excavators hav...
