[0002] During the long-term use of large ships, the bottom of the ship will rust and grow seaweeds, shellfish, etc., and it is necessary to use an ultra-high pressure water rust removal work vehicle to clean and remove rust from the ship. In the existing rust removal work vehicle, the cleaning mechanism is arranged on the telescopic arm (adopting the same multi-section structure as the telescopic arm of construction machinery), and the ultra-high pressure water pipe and the sewage recovery pipe are arranged along the length direction of the telescopic arm. The sewage recovery pipe can vacuum-recover the sewage in the cleaning mechanism to avoid the splashing of sewage and the waste of water resources during the rust removal process. In the traditional pipeline layout, the sewage recovery pipe is a flexible hose with a fixed length.

[0029] In the present utility model, unless otherwise clearly defined and limited, terms such as "arranged", "installed", "connected", "joined", "fixed", etc. shall be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a mechanical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] As Figure 1 , Figure 4 and Figure 7 shown, a multi-stage telescopic rust-removing sewage recovery pipeline structure includes a sewage recovery pipe main body 1, which is arranged parallel to one side of the telescopic arm 2. A fixing component 3 is connected between the sewage recovery pipe main body and the telescopic arm. The sewage recovery pipe main body includes a plurality of circular sleeves 101 arranged in increasing or decreasing order of diameter and sleeved together in sequence. There is a clearance fit between every two adjacent circular sleeves and a sealing sliding component is provided. The sealing sliding component realizes the sealing performance between every two adjacent circular sleeves. The number of circular sleeves can be freely adjusted according to actual needs. The number of circular sleeves and the fixing components are the same as the number of sections of the telescopic arm and are connected in one-to-one correspondence. Each section of the circular sleeve is connected to the corresponding section of the telescopic arm through a fixing component. In this embodiment, the number of circular sleeves is three, that is, the sewage recovery pipe main body is a three-section pipe, and the telescopic arm is also a three-section arm, and the number of fixing components is three. The length adjustment of the telescopic arm is prior art, adopting the same rope row telescopic arm or single cylinder pin type telescopic arm technology as that of engineering mechanical equipment (such as a crane), which will not be elaborated here. The circular sleeve is made of stainless steel. The length of the sewage recovery pipe main body can change synchronously with the telescopic arm, which can not only accommodate the circular sleeve, but also solve the problem of the bending and suspension of the flexible hose in the prior art, improve the strength of the sewage recovery pipe main body, extend the service life, and improve the overall aesthetics of the rust-removing device.

[0031] Combined with Figures 1 to 3 shown, the fixing component includes a fixing seat 301 and a locking member 302. One end of the fixing seat is fixedly connected to the telescopic arm, and the other end is provided with a first arc-shaped groove 3011. The locking member is connected to the fixing seat and a second arc-shaped groove 3021 is provided on the side close to the fixing seat. The first arc-shaped groove and the second arc-shaped groove are both semi-circular and cooperate with each other to form a circular hole. The circular sleeve is arranged in the circular hole. The two sides of the locking member and the fixing seat are assembled and connected by a first locking screw 303, which is convenient for the disassembly and assembly of the locking member and the fixing seat and facilitates the maintenance and replacement of the sewage recovery pipe main body. To improve the connection stability between the fixing component and the circular sleeve, a retaining ring 7 is provided at one end of the circular sleeve with a larger diameter. The retaining ring is located on one side of the positioning sleeve, and the fixing component is arranged between the positioning sleeve and the retaining ring.

[0032] Combined with Figure 4 , Figure 5 andFigure 6 As shown in the figure, the sealed sliding assembly includes a positioning sleeve 4, a sealing washer 5 and a limit ring 6. The positioning sleeve is provided at one end of the circular sleeve with a larger diameter. The sealing washer is arranged inside the positioning sleeve and is in close contact with the outer wall of the circular sleeve with a smaller diameter passing through the positioning sleeve, and can slide along the outer wall of the circular sleeve with a smaller diameter, playing a sealing role. A limit ring is provided on the outer wall of one end inside the circular sleeve with a larger diameter, and the outer diameter of the limit ring is larger than the inner diameter of the sealing washer. By using the blocking of the sealing washer on the limit ring, the circular sleeve with a smaller diameter is prevented from slipping out of the circular sleeve with a larger diameter.

[0033] The positioning sleeve includes a positioning seat 401, an annular cover plate 402 and a second locking screw 403. The vertical cross-section of the positioning seat is a U-shaped structure with a first through hole 4011 in the middle. One end of the positioning seat away from the first through hole is connected to the annular cover plate by the second locking screw. A clamping groove 404 is formed between the annular cover plate and the inner wall of the positioning seat. The sealing washer is embedded in the clamping groove. The connection between the annular cover plate and the positioning seat is detachable, which can clamp and fix the sealing washer and is also convenient for replacing the sealing washer. A second through hole 4021 is provided in the middle of the annular cover plate. The inner diameter of the sealing washer, the inner diameter of the second through hole, the outer diameter of the limit ring, and the inner diameter of the first through hole increase in sequence. When the annular cover plate is removed and the sealing washer is taken out, the circular sleeve with a smaller diameter can directly pass through the first through hole on the positioning seat and be taken out from the circular sleeve with a larger diameter.

[0034] A plurality of annular grooves 501 are evenly spaced along the central axis direction on the inner wall of the sealing washer to improve its sealing performance. To further facilitate the replacement, disassembly and assembly of each sealing washer, the annular cover plate is composed of two semi-circular plates spliced together, and the sealing washer is composed of two semi-circular washers spliced together. After unscrewing the second locking screw, the two annular cover plates can be removed, and the sealing washer inside can be replaced, which is convenient for maintenance.

[0035] The working principle of the present utility model is as follows:

[0036] As Figures 1 to 7 shown in the figure, since each circular sleeve 101 of the main body 1 of the sewage recovery pipe is respectively connected to each telescopic arm 2, when the rust removal operation vehicle drives the telescopic arm 2 to perform telescopic movement to change the position of the cleaning mechanism 8, each circular sleeve 101 moves synchronously with the movement of each telescopic arm. The sealing washer 5 can ensure the sealing performance between every two adjacent circular sleeves 101. When it is necessary to replace one of the sealing washers 5, only the corresponding second locking screw 403 needs to be loosened, and after removing the annular cover plate 402, the sealing washer 5 on its inner wall can be replaced, and the operation is simple and convenient.

[0037] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, it is intended to embrace all changes within the meaning and scope of the equivalent elements of the claims in the present utility model.
