[0021] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] A working boat comprises a hull 1 and a river clearing mechanism 2 installed on the hull 1. Figure 1 shown.

[0023] The river channel obstacle clearing mechanism 2 includes a turning frame 21 installed at the bow or stern of the ship, and a clearing roller 22 is arranged on the turning frame 21, and a row of nails 23 is installed on the clearing roller 22. There are multiple groups of the row of nails 23, and each group of the row of nails 23 has multiple rows of nails. The multiple rows of nails 23 in each group are spaced and distributed along the axial direction of the clearing roller 22. The nail tips of the rows of nails 23 in different groups face different directions, and the axis center lines of all the rows of nails 23 intersect with the axis center line of the clearing roller 22. The river channel obstacle clearing mechanism 2 also includes a buoyancy box 24 detachably installed on the turning frame 21. In this example, the turning frame 21 is installed at the stern of the ship, and the row of nails 23 includes at least two groups of rows of nails 23 with the nail tips facing downward, and the angles between the axis center lines of the two groups of rows of nails 23 and the horizontal plane where the turning frame 21 is located are 40° and 70° respectively. Here, the row of nails 23 are arranged at the above angles, which is conducive to the obstacle clearing mechanism to check for obstacles such as waste fishing nets and ground dragons.

[0024] Here, there are at least two buoyancy boxes 24, and the two buoyancy boxes 24 are detachably mounted on the axial ends of the obstacle removal roller 22, see Figure 1 As shown. Specifically, the buoy 24 here can be rotatably arranged around the axis of the obstacle removal roller 22, and the rotating surface of the buoy 24 is a smooth curved surface. Preferably, the buoy 24 adopts a cylindrical structure, and the buoy 24 and the obstacle removal roller 22 are arranged coaxially, or the buoy 24 adopts a spherical structure, and the center of the buoy 24 falls on the axis of the obstacle removal roller 22. By setting the buoy 24, the situation in which the flip frame 21 sinks into the mud is avoided. The rotating surface of the buoy 24 is set to be a smooth curved surface, so that even if the buoy 24 is sunk into the mud, the friction resistance between it and the mud can be reduced, and it can be easily pulled out of the mud.

[0025] In this example, the turning frame 21 includes a main support rod 211 and a secondary support rod 212. Figure 1 As shown, there are at least two main support rods 211, and the secondary support rods 212 are connected between the main support rods 211 and the main support rods 211 and between the main support rods 211 and the obstacle removal roller 22. One end of the main support rod 211 is hinged on the hull 1, and the other end is welded to the obstacle removal roller 22. In this example, a secondary support rod 212 parallel to the obstacle removal roller 22 is installed between the two main support rods 211, and a secondary support rod 212 arranged in a triangle is additionally arranged between the secondary support rod 212 and the obstacle removal roller 22. A plurality of secondary support rods 212 are also added between the main support rod 212 and the obstacle removal roller 22, so that the turning frame 21 is wing-shaped. This arrangement greatly improves the force strength of the turning frame 21, makes the turning frame 21 not easily deformed, and prolongs the service life of the turning frame 21.

[0026] In this example, a positioning pile assembly 3 is installed on the hull 1, see Figure 2 As shown, the positioning pile assembly 3 includes a guide sleeve 31 with a central inner cavity, a positioning pile 32 that is inserted into the guide sleeve 31 and slides along the length extension direction of the guide sleeve 31, and a guide column 33 that is arranged parallel to the guide sleeve 31 is also installed on the outer surface of the guide sleeve 31. The guide column 33 has a hollow inner cavity. The positioning pile assembly 3 also includes a guide rod 34 with one end inserted into the inner cavity of the guide column 33 and one end connected to the positioning pile 32. The guide rod 34 slides along the length direction of the guide column 33 with the sliding of the positioning pile 32. Here, one end of the guide rod 34 is connected to the lower end of the positioning pile 32, which plays a guiding and supporting role in the lifting process of the positioning pile 32. When the positioning pile 32 is inserted underwater, the influence of the water flow on the positioning pile 32 is reduced, and the positioning pile 32 is prevented from running off when inserted into the mud. The positioning pile assembly 3 is set up to prevent the hull 1 from shaking when clearing obstacles, so as to insert the positioning pile 32 into the river channel 8 to keep the hull 1 balanced.

[0027] The positioning pile assembly 3 can be installed on the bow or stern of the ship in a flip manner. An "L-shaped" mounting plate 5 is installed on the hull for installing the positioning pile assembly 3. Figure 2 As shown, the long side of the "L"-shaped mounting plate 5 is mounted on the upper surface of the hull 1, and the short side is against the front end surface of the bow or the rear end surface of the stern. The workboat also includes a traction plate 6 with one end hinged on the long side of the "L"-shaped mounting plate 5 and the other end fixedly connected to the guide sleeve 31, and a connecting shaft 7 with one end hinged on the long side of the "L"-shaped mounting plate 5 and the other end hinged on the guide sleeve 31. The connecting shaft 7 is a telescopic shaft. In this example, there are two groups of the positioning pile assembly 3, which are respectively located on the left and right sides of the turning frame 21. The positioning pile assembly 3 is installed in this way, which is easy to operate. Of course, the positioning pile assembly 3 can also be directly fixed on the bow or stern through the mounting frame.

[0028] Here, the connecting shaft 7 includes a connecting shaft I71 having a hollow inner cavity and a connecting shaft II72 with one end movably inserted in the inner cavity of the connecting shaft I71. One end of the connecting shaft I71 is hinged on the "L-shaped" mounting plate 5, and the other end of the connecting shaft II72 is hinged on the outer wall of the guide sleeve 31.

[0029] Here, the outer surface of the guide sleeve 31 is also fixed with a stopper 35 that can press against the short side of the "L"-shaped plate. When the river channel obstacle clearing mechanism 2 detects an obstacle and clears it, the guide sleeve 31 is turned down, the connecting shaft II 72 extends out of the connecting shaft I 71, and the traction plate 6 rotates away from the hull 1. When the stopper 35 on the guide sleeve 31 presses against the short side of the "L"-shaped plate, it ensures that the positioning pile 32 is in the vertical plane, and then the positioning pile 32 is inserted downward into the river channel 8. When the workboat is running normally, the connecting shaft II 72 is accommodated in the connecting shaft I 71, the traction plate 6 rotates toward the bow position, the positioning pile assembly 3 is turned to a horizontal position and placed at the stern, and the guide rod 34 is retracted into the guide column 33.

[0030] In this example, the hull 1 is also equipped with a traction mechanism 4 for pulling the turning frame 21, see Figure 1 As shown, the traction mechanism 4 includes a winch 41 installed on the hull 1 and a cable 42 with one end wound around the winch 41 and the other end connected to the turning frame 21. Here, the other end of the cable 42 is connected to the main support rod 211. In this example, there are two main support rods 211, and there are also two cables 42 in the traction mechanism 4. The other ends of the two cables 42 are respectively connected to the main support rods corresponding thereto.

[0031] In this example, the main support rod can be a telescopic rod. When the obstacle is pulled, the main support rod is retracted to the bow position to pull the cable 42, which can shorten the traction distance of the cable 42, reduce the traction force, and facilitate the cleaning of the operator.

[0032] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
