Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering, in particular to a quick access device for a mobile power generation vehicle. Background Art

[0002] The generator truck is a special vehicle equipped with a power supply device. It can be equipped with a battery pack, a diesel generator set, or a steam generator set. It is widely used to transfer power to electrical equipment such as ring network cabinets, branch boxes, and switch cabinets. When in use, it generally needs to be connected through an access device.

[0003] For example, the mobile power generation vehicle quick access device with announcement number CN205791769U includes a vehicle body, casters, a quick cable connector and a low-voltage circuit breaker. The vehicle body is a rectangular cavity structure with four casters installed at the bottom. The quick cable connector and the low-voltage circuit breaker are arranged side by side in the vehicle body. This device has a simple structure and a reasonable design. When this device is not used, the power generation vehicle needs to lay at least 50 meters of standard vehicle cables. After adopting this device, in the process of providing emergency power supply to users, the power generation vehicle can be conveniently parked and positioned next to the device, and a low-voltage cable of about 10 meters can be used to quickly access the user's low-voltage distribution system, effectively shortening the working time of laying the output cable of the power generation vehicle. It is estimated that each cable can save about 10 minutes of laying time.

[0004] There are still some shortcomings in the above patents, such as: it connects the lines by setting up cable connectors, its interface is relatively simple, and a matching connector is required. When used for emergency power supply, the connecting wires of some equipment are bare wires at one end, which is inconvenient to access and reduces the access efficiency; common terminal blocks are usually made by wrapping the copper wire at the exposed end of the wire around the terminal post, and then tightening it with a nut. After wrapping, the operator needs to manually position it. However, the manual positioning method is not convenient for tightening the nut, and it is easy to loosen and fall off, resulting in repeated operations.

[0005] Therefore, we propose a mobile power generation vehicle quick access device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figure 1-Figure 4A mobile power generation vehicle quick access device comprises a mobile base 1, a bracket 2 fixedly connected to the top surface of the mobile base 1 and a protective box 3 fixedly connected to the top of the bracket 2, a quick-connect plate 4 is slidably arranged on the inner wall of the protective box 3, a plurality of wire insertion holes 5 are symmetrically arranged on one side of the top surface of the quick-connect plate 4, a plurality of terminal assemblies 6 are symmetrically fixedly installed on the other side of the top surface of the quick-connect plate 4, a circuit breaker 7 is fixedly connected to the middle of the top surface of the quick-connect plate 4, a lifting assembly 8 is built into the protective box 3, the lifting assembly 8 is arranged at the bottom of the quick-connect plate 4, and the top of the lifting assembly 8 is rotatably connected to the bottom surface of the quick-connect plate 4.

[0025] A plurality of universal wheels 11 are fixedly mounted on the bottom surface of the mobile base 1 , and a winding frame 21 is fixedly connected to the side wall of the bracket 2 .

[0026] A handle 31 is fixedly provided on the side wall of the protection box 3 , and a cover plate 32 is rotatably connected to the top surface of the protection box 3 .

[0027] In this embodiment: after the access device is moved to the connection position, the line of the power generation vehicle is inserted into the wire insertion hole 5, and a long wire is wound on the winding frame 21, which is convenient for use when the access distance is far; when connecting to a device that is not equipped with a corresponding connector, wiring is performed through the terminal assembly 6. When connecting, the exposed copper wire at one end of the device connection line is cross-wound onto the winding protrusion 63 to preliminarily fix the connection line. The winding protrusion 63 prevents the connection line from loosening toward the outer circle after winding, resulting in the need for repeated operations and reducing the access efficiency. After winding is completed, tighten the nut 65 so that the wire pressing plate 66 set at its bottom end presses the connection line and the copper sheet 62 to fix it.

[0028] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 5 The lifting assembly 8 includes a bidirectional screw rod 81 that is rotatably connected to the inner wall of the protection box 3 and a sliding rod 82 that is fixedly connected to the inner wall of the protection box 3.
