Meanwhile, the accelerator is a large-scale electrical device, consumes a large amount of electric energy, converts the electric energy into electronic energy, has the conversion efficiency of about 14%, generates a large amount of heat energy in the process, and is required to be provided with a complete constant temperature and cooling water cooling circulation system for radiating heat for the accelerator main body and the electrical cabinet in order to ensure the normal operation of the accelerator and combine the working characteristics of key components. Moreover, the existing constant temperature and cooling water cooling circulation systems such as constant temperature water cooling machine cabinets, water cooling external machines, water diversion cabinets (placed inside the protective body) and the like all need pipelines to penetrate through the protective body to be communicated with the water diversion machine cabinets or water sources.
However, due to the structural design characteristics of reinforced concrete of the protection body and the design characteristics of multipath pipelines of a circulating system (more than 12 pipelines in general), the direct penetration of the protection body for pipeline distribution is difficult to construct (adjacent pipelines are easy to penetrate and are inaccurate in perforation positioning and blocked by steel bars), the cost is high, a hose is needed for a wall penetrating pipe, copper pipes are respectively connected to two ends of the wall penetrating pipe, and the wall penetrating pipe is difficult to install and overhaul; on the other hand, the problems of radiation leakage and the like of the high-energy electron beam and the X-ray are easily caused by punching and damaging the shielding of the shielding body.

Preferably, the water diversion pipes of the integrated water pipe mechanism are distributed in multiple layers, and the adjacent upper and lower water diversion pipes are aligned in an inserting mode, so that the distance between the adjacent water diversion pipes is increased.
Preferably, the lengths of the pipe orifices of the upper and lower adjacent layers of water diversion pipes of the integrated water pipe mechanism, which extend out of the concrete protection body, are increased stepwise from the upper layer to the lower layer, namely, the lengths of the pipe orifices of the uppermost layer of water diversion pipes, which extend out of the concrete protection body, are shortest, and the lengths of the lower layer of water diversion pipes, which extend out of the concrete protection body, are increased stepwise, so that the interfaces of the upper and lower adjacent layers of water diversion pipes are staggered, and enough installation space is reserved.
Preferably, the ports of the water diversion pipes in the integrated water pipe mechanism are designed by adopting standard external wires, and the water pipes matched with the water diversion pipes can be linked by using standard components, so that the water diversion pipe mechanism is convenient to install, and meanwhile, the cost of component processing is reduced, and the installation time is shortened.
