[0018] The clamping plate includes an upper clamping plate 2 and a lower clamping plate 3 of the same semicircular structure, and the upper clamping plate 2 and the lower clamping plate 3 are used to install the entire device on the pipe cleaning ball transmitter and receiver. Both ends of the upper clamping plate 2 and the lower clamping plate 3 extend outward to form a connecting arm. After the upper clamping plate 2 and the lower clamping plate 3 are buckled, the connecting arms of the two are parallel to each other. Circular holes are provided on the connecting arms of the upper clamping plate 2 and the lower clamping plate 3, and the adjustable clamp 1 is inserted into the circular holes. The adjustable clamp 1 includes a bolt, and after the bolt passes through the circular holes on the same side of the upper clamping plate 2 and the lower clamping plate 3, fixing nuts 15 are respectively sleeved from both ends thereof, and the fixing nuts 15 are tightened to achieve the connection and locking of the upper clamping plate 2 and the lower clamping plate 3. Preferably, the material of the clamping plate of the present application is Q345 steel, and its size can be selected according to the outer diameter of the ball receiver, with a diameter range of 20cm~60cm, a width range of 10~15cm, and a thickness range of 0.5~1cm; the material of the bolt of the adjustable clamp 1 is 45 steel, with a diameter range of 0.9cm~3.5cm; the material of the fixing nut 15 is 45 steel.

[0019] An adjustable fixed shaft is installed on the outer wall of the clamping plate, the adjustable fixed shaft is provided with a thread, and a movable sleeve is sleeved on the adjustable fixed shaft. Specifically, an upper adjustable fixed shaft 6 and a lower adjustable fixed shaft 7 are respectively provided on the top of the upper clamping plate 2 and the bottom of the lower clamping plate 3, and an upper movable sleeve 8 and a lower movable sleeve 9 are respectively sleeved on the upper adjustable fixed shaft 6 and the lower adjustable fixed shaft 7. Two fixing nuts 15 are also sleeved on the upper adjustable fixed shaft 6 and the lower adjustable fixed shaft 7, and the two fixing nuts 15 are respectively located on both sides of the movable sleeve. By adjusting the positions of the two fixing nuts 15 on the adjustable fixed shaft, the positioning and limiting of the movable sleeve are achieved. The material of the adjustable fixed shaft of this application is 45# steel, with a diameter of 2.5cm and a length of 25cm; the material of the movable sleeve is Q345 steel, with a diameter of 2.5cm.

[0020] The movable sleeve of the present application is connected to the threaded tie rod, and the threaded tie rod is connected to the anti-impact plate. Specifically, the upper movable sleeve 8 and the lower movable sleeve 9 are welded to the upper threaded tie rod 10 and the lower threaded tie rod 11 respectively, and the free ends of the upper threaded tie rod 10 and the lower threaded tie rod 11 are connected to the same anti-impact plate 14. Preferably, the upper and lower sides of the anti-impact plate 14 respectively form an upper movable groove 12 and a lower movable groove 13, and the length range of the movable groove is 1~10cm and the width is 2.5cm; the upper threaded tie rod 10 and the lower threaded tie rod 11 respectively penetrate the upper movable groove 12 and the lower movable groove 13, and the fixing nuts 15 are sleeved on both sides of the anti-impact plate 14 on the threaded tie rod, and the positioning and limiting of the anti-impact plate 14 are achieved by locking the fixing nuts 15. The anti-impact plate 14 of the utility model can move along the threaded tie rod, so as to adjust the distance between the quick-opening blind plate and the anti-impact plate 14, so that the device is suitable for different types of cleaning ball launchers and receivers, ensuring the safety protection effect of the device. The threaded pull rod of the present application is made of 45# steel, with a length range of 40~60cm and a diameter of 2.5cm; the anti-impact plate is made of Q345 steel, and its size can be selected according to the outer diameter of the ball receiver, with a length range of 20cm~60cm, a width range of 10~20cm, and a thickness range of 1~2cm.

The limiters are located on the side of the adjustable fixed shaft away from the threaded rod, and compared with the adjustable fixed shaft, the position of the limiters on the clamping plate is closer to the quick-opening blind plate. The setting of the limiters can prevent the threaded rod and the anti-impact plate from excessively rotating and thus deviating from the quick-opening blind plate. The material of the limiter of the utility model is 45# steel, and the length range is 4cm~8cm.
