[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] In the description of the present utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. The terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; for ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0023] like Figure 1-4 As shown, a battery-start trailer includes a body 1. The body 1 is an integrated structure, and the interior is divided into a battery box 3 at the front and an equipment operation box 2 at the rear by an insulating and fire-resistant partition. A battery box cover 6 is movably installed on the top of the battery box 3, and an operation box cover 5 is movably installed obliquely on the top of the equipment operation box 2. An electrical control box 4 is fixedly installed on the top of the inner wall of the equipment operation box 2. The remaining internal space of the equipment operation box 2 is a storage space for placing rolled-up cables. A tail towing hook 8 is also fixedly installed on the bottom of the rear end of the equipment operation box 2 to facilitate the continued towing of other vehicles.

[0024] The operating box cover 5 and the battery box cover 6 both adopt an independent flip-up structure. When the cover needs to be opened, the positioning support rod and the cover connecting rod can be connected to support and position the cover, which is convenient for the maintenance, inspection and overhaul of the battery pack and the electrical control box 4. When the cover needs to be closed, the support rod is removed and placed in place. After the upper cover is closed, the tightening handles on both sides are locked to make the cover of the equipment and the rubber sealing strip at the edge of the box body more tightly pressed, ensuring the sealing of the box body and preventing rain, sand, dust, etc. from entering when used in special environments. This structure fully meets the sealing requirements of the equipment. In addition, the inner layer material of the battery box 3 structure is made of glass fiber reinforced plastic for corrosion resistance, and the installation positioning plate of the battery pack is made of anti-corrosion plastic plate, which can meet the anti-corrosion function requirements of the equipment. The edges and corners of the outside of the equipment are blunted or rounded; for parts that are susceptible to corrosion and need frequent maintenance and replacement, anti-corrosion measures are provided from the structure. Under the premise of meeting the requirements of mechanical strength and electrical performance, the equipment materials have good resistance to moisture, salt spray, weathering, mildew corrosion and weathering. At the same time, the battery box 3 uses a corrosion-resistant glass fiber reinforced plastic tank to effectively prevent the corrosion of the metal shell due to battery acid overflow. The battery pack base uses a plastic plate assembly to facilitate battery positioning, which can be applied to the installation of batteries of different specifications and can also effectively solve the battery acid corrosion.

[0025] like Figure 2 As shown, a vehicle bottom beam 10 is fixedly installed at the bottom of the vehicle body 1, a pair of main wheels 9 are installed below the vehicle bottom beam 10, and a leaf spring suspension 11 is installed between the vehicle bottom beam 10 and the main wheels 9, which effectively reduces the impact of road bumps on electrical components such as the battery pack in the vehicle body 1 and the electrical control box 4 during field operations.

[0026] like Figure 1-5 As shown, the front end of the vehicle bottom beam 10 is movably connected to a triangular front trailer 7 through an adjusting device 12, and a front wheel 13 is also installed at the bottom of the adjusting device 12, and the triangular front trailer 7 and the front wheel 13 are both rotatably connected to the adjusting device 12. The adjusting device 12 mainly includes a semicircular connecting plate 14, which is fixedly welded and installed at the front end of the vehicle bottom beam 10, and the tail of the triangular front trailer 7 is inserted into the middle of the connecting plate 14 and is rotatably connected through a connecting shaft 16. The front wheel 13 is a single-wheel structure and is installed on a wheel frame 15. The top of the wheel frame 15 is also inserted into the connecting plate 14 and is rotatably connected to the connecting plate 14 through the connecting shaft 16, and the top of the wheel frame 15 is fixedly connected to the tail of the triangular front trailer 7. The arc edge of the connecting plate 14 is provided with a 1 / 4 circle adjusting hole 17 with the connecting shaft 16 as a circle, and an adjusting hole 17 is also provided on the triangular front trailer 7 accordingly, and the connecting plate 14 and the adjusting hole 17 on the triangular front trailer 7 are fixed by inserting an adjusting shaft pin 18.

[0027] In actual use, the front wheel 13 can be retracted and extended according to the usage. When moving a short distance, parking the trailer, powering on for inspection or starting guarantee, the front wheel 13 is lowered to the ground and locked to form a supporting effect, thereby ensuring that the equipment is level and does not tilt. When long-distance towing is required, it is necessary to pull out the adjustment axle pin 18, then lift the triangular front trailer 7 to a height suitable for connecting the towing vehicle, and then insert the adjustment axle pin 18 into the corresponding adjustment hole 17 again; and since the triangular front trailer 7 is fixedly connected to the wheel frame 15 on which the front wheel 13 is installed, when the triangular front trailer 7 is lifted, the front wheel 13 is also retracted synchronously, because the main function of the front wheel 13 is support and short-distance movement, it is not suitable as a moving wheel for long-distance movement, so as to avoid the front wheel 13 from contacting the road surface and being damaged during towing movement, and at the same time, it also reduces the bumps caused by the movement of the small-diameter front wheel 13.

[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
