[0030] The specific technical solutions of the present invention are further described below with reference to the accompanying drawings to help those skilled in the art further understand the present invention without limiting the rights thereof.

[0031] Example 1, reference Figure 1-2 A multifunctional obstacle breaker for landing includes a hull body with a rudder, which is composed of two pontoons 1 arranged side by side. The two pontoons 1 are fixedly connected at the sides and are internally interconnected. The pontoons 1 are sequentially arranged at the front end of the pontoon 1 and the rear end of the pontoon 1 according to the forward and backward directions of the hull body. A propeller 2 and a thruster used in conjunction with the propeller 2 are provided at the rear end of the pontoon 1. The rudder, propeller 2 and thruster are all existing technologies, so the principle and method of their coordinated work are not repeated here. The model and specifications can be customized according to the use requirements.

[0032] The left and right obstacle-breaking parts are arranged on the left and right sides of the front end of the buoy 1, and include an obstacle-breaking cutting tool I3, a transmission shaft I4 connected to the obstacle-breaking cutting tool I3, and a rotating power mechanism I5 connected to the transmission shaft I4 to drive the obstacle-breaking cutting tool I3 to rotate and perform demolition and cutting on the targets on the left and right sides of the front end of the buoy 1. The rotating power mechanism I5 and the rotating power mechanism II8 can use servo motors;

[0033] The front obstacle-breaking part is arranged in front of the front end of the pontoon 1 and is located between the left and right obstacle-breaking parts. It includes an obstacle-breaking cutting tool Ⅱ6, a transmission shaft Ⅱ7 connected to the obstacle-breaking cutting tool Ⅱ6, and a rotating power mechanism Ⅱ8 connected to the transmission shaft Ⅱ7 to drive the obstacle-breaking cutting tool Ⅱ6 to rotate and perform demolition and cutting on the target in front of the front end of the pontoon 1.

[0034] Example 2, a multifunctional obstacle breaker for landing as described in Example 1, wherein the front end of the buoy 1 is arranged in a cone shape, and the two buoys 1 are combined into a cone-shaped structure.

[0035] On the left and right inclined surfaces of the front end of the buoy 1, there are two side mounting grooves 9 for mounting the left and right barrier-breaking parts. The two side mounting grooves 9 are square grooves, and the transmission shaft I4 is rotatably mounted in the two side mounting grooves 9;

[0036] A front mounting groove 10 for mounting the front obstacle-breaking portion is provided at the front end of the buoy 1 . The front mounting groove 10 is a square groove, and the transmission shaft II 7 is rotatably mounted in the front mounting groove 10 .

[0037] Example 3, a multifunctional obstacle breaker for landing as described in Example 1, the obstacle-breaking cutting tool I3 is a tungsten steel tooth piece, the shape of the tungsten steel tooth piece is customized according to the use requirements, for example, it is set in a regular polygonal shape, and the obstacle-breaking cutting tool I3 is arranged equidistantly along the axial direction of the transmission shaft I4.

[0038] Example 4, a multifunctional obstacle breaker for landing as described in Example 1, wherein the obstacle-breaking cutting tool II6 is a tungsten steel tooth piece, and multiple groups of obstacle-breaking cutting tools II6 are arranged equidistantly along the axial direction of the transmission shaft II7, and the sizes of the multiple groups of obstacle-breaking cutting tools II6 are arranged in an increasing manner from front to back.

[0039] Example 5, a multifunctional obstacle breaker for landing as described in Example 1, is provided with a controller in the buoy 1 for driving the rotary power mechanism I5 and the rotary power mechanism II8 to work.

[0040] Example 6, a multifunctional obstacle breaker for landing described in Example 1, wherein a plurality of electromagnets 11 are equidistantly arranged on both sides of the buoy 1, and a rechargeable battery for powering the electromagnets 11 is installed in the buoy 1.

[0041] In Example 6, the electromagnets 11 located on both sides of the pontoon 1 can attract the rail barrages on both sides of the pontoon 1 to a certain extent. The attracted rail barrages can be slightly displaced, so that the rail barrages cut by the obstacle cutting tool I3 and the obstacle cutting tool II6 are attracted to the bottom of the pontoon 1 and pressed by the tungsten steel walking wheel described below. It should be noted that even if the weight of some rail barrages is too large, resulting in the suction force of the electromagnet 11 being insufficient to attract the rail barrages, it will not affect the cutting of the rail barrages by the obstacle cutting tool I3 and the obstacle cutting tool II6. The rail barrages after cutting can still press the tungsten steel walking wheel at the bottom of the pontoon 1. Specifically, the electromagnet 11 can be installed on the bottom inner wall of the pontoon 11.

[0042] Example 7, the multifunctional obstacle breaker for landing described in Example 5, further includes a walking mechanism, which includes:

[0043] A plurality of transmission shafts III 12, which are rotatably mounted on the bottom of the buoy 1;

[0044] Several tungsten steel wheels for travel are fixedly mounted on the outer circumference of the transmission shaft III12. The number of tungsten steel wheels can be selected according to the use requirements.

[0045] The reduction gear box 13 cooperates with the transmission shaft III 12 to provide rotational force to the transmission shaft III 12 , and the power supply of the reduction gear box 13 is electrically connected to the controller through a power line.

[0046] Example 8, a multifunctional obstacle breaker for landing as described in Example 5, is provided with a launching slot 14 at the upper front end of the pontoon 1, and the launching slot 14 is a square slot. The launching slot 14 is sequentially arranged as the front end of the launching slot 14 and the rear end of the launching slot 14 according to the forward and backward directions of the hull body, and a hydraulic telescopic rod 15 is fixedly installed on the inner wall of the rear end of the launching slot 14. The hydraulic telescopic rod 15 is a prior art and can be selected according to the use requirements. A columnar hammer 16 is installed at the telescopic end of the hydraulic telescopic rod 15, and the columnar hammer 16 is a cylindrical body with a spherical front end. A small pump station for driving the hydraulic telescopic rod 15 is installed in the pontoon 1, and the signal input end of the small pump station is connected to the controller through a communication line.

[0047] Example 9, a multifunctional obstacle breaker for landing described in Example 1, wherein the angle between the front end of the buoy 1 and the middle of the buoy 1 is 45°-75°, specifically 70°.

[0048] 10. A method for removing obstacles using any one of the multifunctional obstacle removers for landing in Examples 1-9.

[0049] (1) Before landing: A camera (not shown) and a high-definition image transmission system compatible with the camera are installed on the hull, which are connected to the controller (not shown) in the buoy via satellite communication equipment. The propeller is started by the controller, and the direction of travel of the hull is guided by the rudder. During travel, the high-definition image transmission system transmits the images captured by the camera to an external image receiving device;

[0050] (2) Landing: When the buoy 1 is stranded, the tungsten steel running wheel at the bottom of the buoy 1 contacts the ground. At this time, the reduction box 13 drives the transmission shaft III 12 to rotate, and the transmission shaft III 12 drives the tungsten steel running wheel to rotate, and the landing operation can be carried out;

[0051] (3) Dismantling operation of rail barrage: After pontoon 1 lands, the controller drives the rotating power mechanism I5 and the rotating power mechanism II8 to work. The power output ends of the rotating power mechanism I5 and the rotating power mechanism II8 drive the transmission shaft I4 and the transmission shaft II7 to rotate. The transmission shaft I4 and the transmission shaft II7 drive the obstacle cutting tool I3 and the obstacle cutting tool II6 to rotate. When the obstacle cutting tool I3 or the obstacle cutting tool II6 contacts the rail barrage on the shore, the rail barrage can be dismantled and cut. After the dismantling and cutting, the rail barrage naturally falls to the ground and is flattened by the tungsten steel walking wheel, which is convenient for subsequent landing equipment to perform landing operations.

[0052] When the multifunctional obstacle breaker is in use, it can cooperate with the controller through external communication equipment, and the obstacle breaker can be driven to the predetermined position through the cooperation of the rudder, propeller 2 and thruster. After the pontoon 1 comes ashore, the obstacle cutting tool I and the obstacle cutting tool II break and cut the rail barracks on the embankment. The rail barracks after breaking and cutting naturally fall to the ground and are pressed and flattened by the tungsten steel walking wheels at the bottom of the pontoon 1, which to a certain extent enables the rail barracks to meet the needs of subsequent armored vehicles and other military landing equipment. Its structural design is reasonable. Specifically, part of the reduction box 13 can also be replaced by a differential with power provided by a rotating power mechanism, and a steering system that cooperates with the differential can be installed to give the multifunctional obstacle breaker a certain steering function. Since remote control of the controller through external equipment is an existing technology, the specific control method and principle of the controller will not be repeated here.
