In complex environments, the first crawler walking assembly 5 or the second wheeled walking assembly 6 can be switched according to the terrain environment, so as to meet the requirement of quickly reaching the working area; The split design of the first vehicle body 3 and the second vehicle body 4 also facilitates the use of a trailer for transfer. The first-level crawler traveling assembly 5 adopts a crawler type, which has the characteristics of large traction and strong passability. In mountainous and hilly areas, the first-level crawler traveling assembly 5 performs well in terms of passability and climbing ability, and can effectively resist tipping and sliding; On a flat road, the secondary wheeled traveling assembly 6 is used. By inputting power into the transfer case 602, the screw rod 603 is driven to rotate. Under the action of the thread, the slider 604 matched therewith is limited by the track 601 and cannot rotate. The slider 604 moves relative to the screw rod 603, driving the connecting rod 1 605 to swing.

The first-level water intake pump 1 can be lifted into the water body by the boom 306. The use of the float 101 can make the first-level water intake pump 1 float on the upper layer of the water body, reducing the blockage and collision damage caused by the first-level water intake pump 1 touching the bottom. The float 101 is designed with a water pipe installation groove that is matched with the first-level water intake pump 1. The float 101, the first-level water intake pump 1 and the water intake pipe are more tightly connected and have strong stability.

[0028] The boom 306 can rotate around the central axis of its vertical part, and the storage basket 307 and the primary water pump 1 are both installed on the horizontal part of the swing path of the boom 306; The lifting arm 306 can be used to lift the water intake pipe in the collection basket 307, and assist in the installation of the water intake pipe and the first-level water intake pump 1, and cooperate with the cylinder 308. When the cylinder 308 is extended, the collection basket 307 can be flipped so that its opening changes from a vertical upward state to a state parallel to the ground, thereby facilitating the loading and unloading of the water intake pipe.

[0029] The reel 305 includes: a bracket 3051 and a hydraulic motor 3052, and the bracket 3051 is connected between the reel 305 and the first vehicle body 3; The fourth pressure output oil circuit of the hydraulic pump 303 establishes a circuit with the hydraulic motor 3052; The reel 305 is used to store the pipes of the hydraulic system and is driven by the hydraulic motor 3052, which saves more effort when retracting and releasing the pipes.

The storage basket 307 can be turned over so that the opening is facing the horizontal direction, which is convenient for loading and unloading the water intake pipe. After the loading and unloading work is completed, the storage basket 307 is placed upright to save floor space.

[0031] The installation height of the upper surface of the rail 601 is consistent with the installation height of the upper surface of the first vehicle body 3; When the storage basket 307 is turned over to a horizontal state, it is limited by the track 601 to prevent the storage basket 307 from over-turning.

[0032] The control assembly 302 is matched with the travel power assembly 301 and the hydraulic pump 303 to facilitate control.

[0033] The secondary booster water pump power assembly 402 is used to provide power for the secondary booster water pump 2, and the control system assembly 403 is used to realize the control of the secondary booster water pump power assembly 402 and the secondary booster water pump 2.
