Under the action of the guide sleeve 314 and the guide pin 312, the flange end 120 at the end of the first bellows 700 can be fine-tuned to ensure accurate connection with the front connecting flange plate 341. In some examples, there are multiple guide assemblies, and the multiple guide assemblies are evenly distributed along the circumference of the flange end 120 of the first bellows 700.

[0066] Figure 8 yes Figure 1 A schematic structural diagram of the support assembly 500; Figure 9 yes Figure 8 A cross-sectional view of the support assembly 500 is provided.

The support cylinder 510 is fixedly connected to the support plate 330; the linear bearing 560 is disposed at the end of the support cylinder 510, and the ball rod 550 is cooperatively disposed in the linear bearing 560. One end of the ball rod 550 extends out of the support cylinder 510 and is connected to the ball socket support 540. The ball socket support 540 is connected to the universal ball support plate 520. The universal ball 530 is cooperatively disposed on the side of the universal ball 530 support seat facing away from the ball socket support 540, and the universal ball 530 abuts against the fixing seat 200. Under the action of the driving assembly 400 and the universal ball 530 , the supporting assembly 500 can move along the fixing seat 200 , thereby adjusting the distance between the flange end 120 of the first bellows 700 and the front connecting flange plate 341 .

[0068] The support plate 330 is disposed at the end of the support tube 510 to seal the support tube 510. The ball rod 550 extends through the support cover 580 into the support tube 510. The adjustment washer 570 is connected to the end of the ball rod 550 away from the ball socket support 540. The compression spring 590 is disposed within the support tube 510 and abuts against the adjustment washer 570, allowing the ball rod 550 to move up and down within the support tube 510. Simultaneously, the compression spring 590 constantly applies pressure to the ball rod 550, which in turn applies pressure to the universal ball 530 through the ball socket support 540 and the universal ball support plate 520, ensuring that the universal ball 530 is constantly pressed against the surface of the fixing base 200.

[0070] Reference Figure 10 As shown, in some examples, the locking assembly includes a mounting base 321, a drive motor 322, a mating nut 323, a lead screw 324, and a locking block 325. The mounting base 321 is connected to the support plate 330, the lead screw 324 is connected to the mounting base 321, and the end of the lead screw 324 is connected to the drive motor 322. The mating nut 323 is connected to the locking block 325. The mating nut 323 is mated with the lead screw 324.

In other examples, the bellows docking device for a large-flow water spray system includes multiple locking assemblies, which are evenly distributed along the outer edge of the support flange, thereby ensuring that the flange end 120 of the first bellows 700 and the front connecting flange 340 are firmly locked together.

[0071] Exemplarily, the locking assembly further includes a first guide assembly 326 , and the first guide assembly 326 includes a first guide rail 3261 and a first slider 3262 .

The first slider 3262 is connected to the locking block 325, and the first slider 3262 is engaged with the first guide rail 3261. The first guide assembly 326 is used to limit and guide the locking block 325, allowing it to move in the radial direction, thereby locking the flange end 120 at the end of the first bellows 700 to the front connecting flange plate 341.

[0073] Continue to refer to Figure 10As shown, the locking assembly also includes a connecting block 327 and a second guide assembly 328, wherein the second guide assembly 328 includes a second guide rail 3281 and a second slider 3282.

Exemplarily, the linear drive member can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. Furthermore, exemplary embodiments include multiple linear drive assemblies 400, with multiple linear drive assemblies 400 simultaneously driving the movement of the support plate 330.
