Indeed, the terms "first," "second," and the like are fully interchangeable.
In the description of the present invention, it should be noted that, unless explicitly stated or limited otherwise, the term "connected" is to be understood broadly, and may be a direct fixed connection between two members, or an indirect fixed connection between two members through a third member; the two parts can be fixedly connected with each other in a fixed position or movably connected with each other in a movable position. The term "fixedly connected" is to be understood in a broad sense and may refer to an undetachable connection in which the relative positions of two parts are constant, or a detachable connection in which the relative positions of two parts are constant. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
When the surface treatment is carried out on a ship, a chemical tank or other equipment, the surface treatment device is moved to a surface to be treated area, high-pressure water is sprayed to the surface to be treated, and impurities such as paint, rust and dirt on the surface to be treated are removed by utilizing the impact force formed by the water jet. This process requires control of three factors: first, the pressure of the water jet needs to be high enough to enable the water jet to rapidly remove surface impurities; secondly, the trajectory formed by the water jet on the surface to be treated is annular, so that the trajectories of the water jet of the plurality of nozzles can basically form a circular area to cover the area to be treated on the surface; thirdly, the spray rod rotates to drive the water jet to form an annular track on the surface to be processed, the impurity removal degree of a certain point position of the surface to be processed, the time for the water jet to stay at the point position and the impact force of the water jet at the point position are related, therefore, the time for the water jet to pass through each point position on the annular track is enough and consistent, the strength of the water jet is enough and consistent, the impurity removal degree of each point position on the annular track is high, the removal degree is uniform and consistent, and the surface efficiency is improved.
However, the surface treatment apparatus of the prior art performs the impurity removing process on the surface to be treated by the impact force of the water jet, and simultaneously drives the spray bar and the rotating shaft to rotate by using the horizontal component of the impact force formed by the water jet and the surface to be treated, so that the water jet sprayed from the nozzle on the spray bar forms an annular track on the surface to be treated, but the following problems still exist: firstly, as the horizontal component shares a part of impact force of the water jet, the impact force of the water jet directly acting on impurity removal is weakened and is not enough to completely remove surface impurities; secondly, because the horizontal component force cannot be stably controlled in the rotation process of the spray rod, and the pressure of the water jet ejected from the nozzle is basically constant, the impact force of the water jet directly acting on the surface to be processed cannot be stably controlled, so that the impurity removal degrees of all point positions on the annular track are inconsistent, the processing time of the surface processing device in the area is prolonged probably because the surface processing effect of local point positions is not good, and the surface processing efficiency is reduced; thirdly, the rotating speed of the spray rod is unstable due to unstable horizontal component force, so that the consistency of water jet impact time of each point on the circular track is poor, the uniformity of impurity removal degree of each point on the circular track is influenced, and meanwhile, the rotating speed of the spray rod cannot be controlled due to the rotary driving mode of the spray rod, so that the surface treatment device has poor adaptability to different application scenes and surface treatment purposes, the included angle between the nozzle and the horizontal direction needs to be adjusted again according to different application scenes and surface treatment purposes, even the water jet pressure at the position sprayed by the nozzle needs to be adjusted, and the working efficiency and the use convenience are greatly reduced; fourthly, the rotating speed of the spray rod is unstable due to the unstable horizontal component force, so that unstable abrasion impact is generated on the sealing element of the rotating body, and the service life of the sealing element of the rotating body is shortened.

As can be seen from the linear velocity and rotation speed relation formula V2 tr rn, the rotation speeds of the nozzles 51 on the spray bar 5 are the rotation speeds n of the spray bar, and the linear velocity V of the nozzles 51 is determined by the distance r from the nozzles 51 to the center of the spray bar, and the linear velocity is larger as r is larger, that is, the time involved in the surface treatment is shorter in unit time, that is, the surface treatment effect of the nozzles 51 is worse as r is larger. Therefore, in the embodiment of the invention, the plurality of nozzles 51 are distributed on the spray bar in a sparse-to-dense manner along the direction outward from the center of rotation 5 of the spray bar, so that the density of the annular tracks formed by the water jets on the surface to be treated far away from the center of rotation is improved, the problem of low surface treatment effect caused by short operation time of the nozzles 51 far away from the center of rotation is solved, and the uniformity of surface treatment in the area of the coverage circle is improved.
