Description

A breaker for reef clearance under water Technical Field The invention relates to the technical field of reef crushing, in particular to a crushing device for underwater reef cleaning. Background In the reef removal operation of a inland waterway and a shallow area of an amphibious transition zone, a traditional large reef explosion ship cannot enter an operation area due to shallow water depth and gentle gradient, and a land drilling machine and crawler equipment are difficult to establish a stable construction platform due to rugged underwater topography. For this reason prior art generally adopts mechanical type gravity rock breaking device, utilizes floating hoisting equipment to carry on heavy rock breaking stick promptly, and free fall after lifting mechanism with the stick body to certain height is lifted, and pound to the reef under water with huge impact kinetic energy repeatedly hammering to realize the reef breakage. However, in the prior art, the gravity rock breaking device mounted on the reef vessel can only provide single vertical impact energy in the actual operation process, and each hammering can only form an isolated crushing pit on the reef surface, so that the capability of converting impact kinetic energy into horizontal or multi-point coupling crushing force is lacking. In the land-water interaction zone, the reefs are in mushroom-shaped or dog-tooth staggered prismatic flat layer structures with big upper part and small lower part, the compressive strength of granite and limestone is far higher than that of the granite and limestone, and stress waves generated by single-point impact are rapidly attenuated in a hemispherical shape, so that effective tensile cracks or shear cracks cannot be induced in the rock mass. In the prior art, the crushing radius is generally enlarged by increasing the weight of a broken stone rod or lifting the broken stone rod, but the breaking radius not only aggravates the equipment overturning risk and the blocking hammer hidden danger, but also only relies on the compression-resistant damage principle of vertical impact, the single-point vertical hammering cannot form a multi-source stress superposition area in the rock body, cracks cannot be expanded and communicated, the rock body between adjacent hammering points is difficult to penetrate and crack, and finally the problem that only one pit is broken and one piece is not cracked is formed. Disclosure of Invention Aiming at the problems in the prior art, the invention aims to provide a crushing device for cleaning underwater reefs, which aims to solve the technical problems. In order to solve the problems, the invention adopts the following technical scheme. The breaking device for underwater reef cleaning comprises a circular ring positioning frame and traction hanging chains which are fixedly connected to the outer edge of the circular ring positioning frame and are arranged at equal intervals in circumference, wherein the traction hanging chains are hung on traction equipment of a workboat, heavy stone smashing blocks positioned at the top of the circle center of the circular ring positioning frame are hoisted through the traction equipment of the workboat, three groups of stretching units are arranged on the circular ring positioning frame at equal intervals in circumference, and broken stone shoveling units are arranged at the bottom of each group of stretching units so as to support the circular ring positioning frame on the underwater reef; The inner ring edge of the circular ring positioning frame is fixedly connected with a plurality of high-toughness pull ropes which are circumferentially and equidistantly arranged, a first reef crushing mechanism is hung and pulled at the center position of the bottom of the circular ring positioning frame through the plurality of high-toughness pull ropes, and three groups of second reef crushing mechanisms are circumferentially and equidistantly arranged on the outer circumference of the first reef crushing mechanism; The first reef crushing mechanism comprises a collision chassis and first detachable stone blocks positioned at the bottom of the collision chassis, the second reef crushing mechanisms comprise second detachable stone blocks, the side edges of the collision chassis are positioned at the top of each second detachable stone block, a pressing and smashing plate is arranged at the position, which is positioned at the top of each second detachable stone block, of the side edge of the collision chassis, and the first detachable stone blocks are driven to smash stone by means of a traction device of a working ship to collide with the collision chassis, and simultaneously, all second detachable stone blocks are pressed down by the pressing and smashing plate for synchronous multipoint crushing. The invention further provides a scheme that the bottom edge of the circular ring positioning frame is fixedly connected with a plurality of main frame rods in
