[0026] The upper end of the arm truss 2 is equipped with a lifting and traction mechanism connected to the interception net frame 4, and the lifting and traction mechanism includes a lifting box 3 installed on the upper end of the arm truss 2. The lower half of the box body of the lifting box 3 is rotatably connected to a winding wheel 18, and the reel end of the winding wheel 18 is wound with a traction rope 6, and the top of the fiber rope of the traction rope 6 is provided with a traction seat 7 connected to the first arm support 8 and the second arm support 11. The upper half of the box body of the lifting box 3 is equipped with a winding motor 19, and the winding motor 19 is connected to the winding wheel 18 through a transmission belt 21.

While the traction rope 6 is rolled up, the interception net frame 4 is pulled to slide along the guide rail direction of the track frame 1, and it is moved out of the water surface and raised to a certain height, so that the staff can stand on the engineering platform and directly collect and process the floating objects.

[0027] The guide rail end of the track frame 1 is slidably connected to the intercepting net frame 4, and the frame back plate of the intercepting net frame 4 is symmetrically installed with a first arm force support 8, and the frame back plate of the intercepting net frame 4 is symmetrically installed with a second arm force support 11 on one side of the first arm force support 8, and both ends of the first arm force support 8 are installed with a first guide wheel 9 guided by the track frame 1, and both ends of the second arm force support 11 are installed with a second guide wheel 10 guided by the track frame 1, and the first guide wheel 9 and the second guide wheel 10 are symmetrically staggered relative to the guide rail direction of the track frame 1.

When a large number of floating objects are intercepted in the interception net frame 4, the winding motor 19 can be controlled to work, and the transmission combination of the pulley A20, the transmission belt 21, and the pulley B22 can be used to drive the winding wheel 18 to rotate, and the traction rope 6 is wound and rolled. While the traction rope 6 is rolled, the interception net frame 4 is pulled to slide along the guide rail direction of the track frame 1. , move it out of the water surface and rise it to a certain height so that the staff can stand on the engineering platform and directly collect and process the floating objects. Later, after the interception net frame 4 is moved up to the same horizontal height as the engineering platform, the wrench tool can be inserted into the output shaft 17 to control the output shaft 17 to rotate. During the rotation process, the transmission worm 16 is driven to rotate, and the meshing transmission of the transmission worm 16 and the transmission worm wheel 15 is used to drive the rotating shaft 14 to rotate, and then the collection box 5 is pushed to flip, and the floating objects that fall into the collection box 5 by the interception net frame 4 are flipped and unloaded. The unloading is simple, convenient, safe and efficient. After the unloading is completed, the interception net frame 4 only needs to be moved into the water again to continuously intercept and collect the floating objects in the river.
