The positioning plate 57 is slidably connected with the insertion rod 53. The outer sleeve of the insertion rod 53 is provided with a tension spring 58. The two ends of the tension spring 58 are respectively fixedly connected to the insertion rod 53 and the positioning plate 57. The upper surface of the base 54 is fixedly connected with an electric push rod 55 for automatically controlling the movement of the arc plate 51. The output end of the electric push rod 55 is fixedly connected to the arc plate 51. The lower surface of the base 54 is provided with a plurality of anti-slip grooves 56 for increasing the friction of the lower surface of the base 54. The anti-slip grooves 56 are evenly distributed on the lower surface of the base 54. One end of the insertion rod 53 is rotatably connected to a pull ring 59 , which is in a circular ring shape. Pulling the pull ring 59 can drive the insertion rod 53 , thereby achieving the effect of conveniently controlling the insertion rod 53 .

[0053] Effects achieved by the supporting device 5: By setting up the supporting device 5, two effects are achieved: first, the connecting pipe 1 can be supported during use to improve its stability during use; second, when the connecting pipe 1 needs to be connected to the external pipes 8 at both ends, the connecting pipe 1 can be temporarily supported with the help of the device, thereby improving the installation convenience of the high-pressure flow automatic control system.

[0054] The working steps of the high pressure flow automatic control system are as follows:

[0055] Step S1, the flow meter 6 can detect the water flow inside the connecting pipe 1, and the valve stem 10 can be rotated to control the valve 9, thereby controlling the water flow inside the connecting pipe 1. When the high-pressure flow automatic control system is needed to automatically control the water flow inside the connecting pipe 1, the flow meter 6 monitors the water flow inside the connecting pipe 1, and the obtained data is transmitted to the central processor;

[0056] Step S2, the central processing unit controls the motor 302 to start, so that the motor 302 starts to drive the driving gear 303 to rotate, the driving gear 303 drives the driven gear 304, and the driven gear 304 drives the valve stem 10 to rotate, so that the valve stem 10 can automatically rotate to control the valve 9, so that the water flow can be automatically controlled;

[0057] Step S3, when it is necessary to open the protective cover 305 to perform maintenance and repair on the components inside, firstly rotate the turntable 311 to drive the screw rod 310 to rotate, the screw rod 310 drives the connecting plate 312, so that the connecting plate 312 moves away from the protective cover 305 in the positioning of the guide rod 320, the connecting plate 312 drives the top plate 313, and the top plate 313 drives the pulley 314 to move away from the limit plate 319;

[0058] In step S4, when the top plate 313 drives the pulley 314 to separate from the limit plate 319, the spring 318 can pull the limit plate 319 to quickly move away from the limit frame 306 until the limit plate 319 is separated from the limit frame 306, thereby achieving the effect of conveniently controlling the limit plate 319. When the limit plate 319 is separated from the limit frame 306, the personnel can hold the handle 307 to drive the protective cover 305 to open it, and then the motor 302 and other components can be maintained and repaired. When the maintenance is completed, the handle 307 is moved again to drive the protective cover 305, and the limit frame 306 on the protective cover 305 is aligned with the limit plate 319. Then the turntable 311 is rotated to drive the screw rod 310 to rotate in the opposite direction. The screw rod 310 drives the connecting plate 312, the connecting plate 312 drives the top plate 313, and the top plate 313 drives the pulley 314, so that the pulley 314 squeezes the oblique waist side of the limit plate 319. At this time, the limit plate 319 will drive the adjustment plate 317 to move along the side of the fixing rod 316. When the limit plate 319 is inserted into the inner wall of the limit frame 306, the installation limit of the protective cover 305 can be completed.

[0059] Among them, the pulley 314 can convert the sliding friction between the top plate 313 and the limit plate 319 into rolling friction, reducing the friction between the top plate 313 and the limit plate 319, and improving the extrusion driving effect of the top plate 313 on the limit plate 319. In addition, the heat dissipation holes 308 can ventilate and dissipate heat for the internal components of the protective cover 305, thereby improving the practicality of the protective cover 305.

[0060] The high pressure flow automatic control system further includes the following working steps:

[0061] Step S5, when using the high-pressure flow automatic control system, it is necessary to connect the connecting pipe 1 with the external pipe 8 by means of the connecting pipe 7. When it is necessary to make the connecting pipe 7 and the external pipe be connected firmly, first move the clamping ring 416 to fit the outer wall of the external pipe 8, then move the screw 414 to insert the clamping ring 416, the welding plate 413 and the clamping ring 416 in sequence, then put the two adjusting rings 415 on the arc surface of the screw 414, and then rotate the two adjusting rings 415 to abut against the two clamping rings 416 respectively;

[0062] Step S6, when the clamping ring 416 is firmly fixed, the connecting frame 411 is rotated to drive the connecting plate 403, and the connecting plate 403 drives the rotating shaft 402 to rotate along the inner wall of the fixing seat 401, and when the auxiliary rod 412 on the connecting frame 411 is aligned with the screw hole 418 on the auxiliary plate 417, the auxiliary rod 412 is rotated to connect with the screw hole 418, and when the auxiliary rod 412 is connected with the screw hole 418, the rotating block 408 is rotated to drive the threaded rod 407 to rotate, and the threaded rod 407 drives the ear plate 409, so that the ear plate 409 drives the connecting frame 411 to move toward the connecting pipe 7 in the guided positioning of the positioning rod 410, and the connecting frame 411 drives the clamping ring 416, and the clamping ring 416 drives the external pipe 8 until one end of the external pipe 8 abuts against the connecting pipe 7, and the installation and fixation of the connecting pipe 7 are completed.

[0063] Among them, during the rotation of the connecting plate 403, the sliding rod 406 fixed on the connecting plate 403 will slide along the inner wall of the sliding hole 405, thereby improving the stability of the connecting plate 403 during the movement process, and when the auxiliary rod 412 on the connecting frame 411 is aligned with the screw hole 418, the arc surface of the sliding rod 406 will abut against one side of the inner wall of the sliding hole 405, so that the connecting frame 411 can be quickly rotated to the specified position. In addition, the coil spring 404 can drive the connecting plate 403 to drive the connecting frame 411 to rotate quickly in the direction close to the external pipe 8, so as to facilitate the adjustment of the connecting frame 411. Finally, by setting the two ends of the screw 414 to a conical structure, the screw 414 can be easily inserted into the retaining ring 416 and the welding plate 413, and the adjusting ring 415 can be easily put on the arc surface of the screw 414.

[0064] Step S7, when it is necessary to support the connecting tube 1 to improve its stability in use, first start the electric push rod 55 to drive the arc plate 51 to abut against the connecting tube 1, and then pull the pull ring 59 to drive the insertion rod 53, so that the insertion rod 53 is inserted into the partition 52 under the drive of the tension spring 58. At this time, the connecting tube 1 can be reinforced and supported, and pulling the pull ring 59 can drive the insertion rod 53, thereby achieving the effect of facilitating the control of the insertion rod 53.
