The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

The end of the inlet and outlet pipe 32 located on the outside of the embedded cavity shell 29 is provided with a filter 31, and the other end of the inlet and outlet pipe 32 is provided with a water pump 30.

[0028] The propulsion assembly 2 is composed of a plurality of propellers 6 arranged outside the cavity shell 1 .

When diving, the multiple groups of water inlet and outlet pipes 32 suck water into the inner cavity of the embedded cavity shell 29, the flexible air bag 33 is compressed and the volume is reduced, the drainage volume of the entire device is reduced, the buoyancy is reduced, and the device reaches the desired position and is suspended while draining. At the same time, the propeller 6 starts to work, and the device can be propelled and turned.

[0035] When the second motor 16 is started, it can drive the main shaft 12 to rotate through the transmission assembly 13, thereby driving the breaking head 11 to rotate for rock breaking action, and the input power of the second motor 16 can be controlled through the power control assembly 14 to control the rock breaking power.

[0036] In use, the device can be directly put into water, when diving, control multiple groups of water inlet and outlet pipes 32 to suck water into the inner cavity of the embedded cavity shell 29, the flexible air bag 33 is compressed to reduce the volume, the drainage volume of the whole device is reduced, the buoyancy is reduced, and after reaching the required position, the drainage is in suspension, at the same time, the propeller 6 is started, and the propeller 6 can be propelled, when turning, up and down turning can be realized by the front and rear air floating assemblies 3 to make the front and rear ends receive different buoyancy by different water suction and drainage, left and right turning can be realized by the left and right inlet and outlet pipes 32 to make the left and right ends receive different reaction forces by different water suction and drainage speeds, after reaching the rock breaking position, the second motor 16 is started, which can drive the main shaft 12 to rotate through the transmission assembly 13, thereby driving the breaking head 11 to rotate for rock breaking action, and the input power of the second motor 16 can be controlled through the power control assembly 14 to control the rock breaking power, at the same time, when the first motor 9 is started, it can drive the bevel gear 10 to rotate, thereby driving multiple bevel gears 8 to rotate synchronously, the bevel gears 8 drive the propeller 6 to rotate through the rotating shaft 7, change the propelling direction of the multiple propellers 6, and use the torque generated by the propelling direction of the propeller 6 to overcome the rock reaction force received by the device.

[0038] When the second motor 16 starts, it can drive the transmission shaft 17 to rotate, thereby driving the transmission disc 18 to rotate, and the transmission disc 18 drives another transmission disc 18 to rotate through a plurality of transmission belts 19, and then drives the main shaft 12 to rotate.

[0039] The device, by setting the transmission disc 18 and the transmission belt 19 as the transmission chain of the power output of the second motor 16 to the main shaft 12, can realize torque transmission and shockproof by the connection of the plurality of transmission belts 19, prevent the vibration of the rock breaking head 11 breaking the rock from being transmitted to the second motor 16 and its fixed parts, and increase the service life of the device.

[0040] In order to solve the power control problem, such as Figures 4-8 As shown, the power control assembly 14 includes a magnetic guide core 24, and a secondary coil 23 and a primary coil 25 wound on the outer wall of the magnetic guide core 24 respectively, the primary coil 25 is connected to an alternating current power supply, the outer wall of the secondary coil 23 is slidably and electrically conductively matched with a sliding contact 22, and one end of the sliding contact 22 and the secondary coil 23 is electrically connected to the input terminal of the second motor 16.

[0042] The outer wall of the transmission disc 18 connected to the outer wall of the transmission shaft 17 is rotatably connected with a shaft moving frame 28, the side wall of the fixed plate 15 is fixed with a guide rod 26, the outer wall of the shaft moving frame 28 is slidably connected to the guide rod 26, and one side of the shaft moving frame 28 and the inner side of the end portion of the guide rod 26 are buckled with a spring 27, and the primary coil 25 is fixed to the outer wall of the shaft moving frame 28.

[0043] When the rock breaking resistance is large, the rotation resistance of the main shaft 12 increases, the torque transmission between the two transmission discs 18 increases, and the torsion angle of the transmission belt 19 increases, and the transmission disc 18 connected to the transmission shaft 17 moves axially against the elastic force of the spring 27, thereby driving the shaft moving frame 28 to move axially, so that the contact position of the primary coil 25 and the secondary coil 23 changes, the number of turns of the secondary coil 23 increases, the input voltage of the second motor 16 increases, and the input power increases, and vice versa.

[0044] The device, by setting the power control assembly 14, based on the principle of electromagnetic induction, the input power of the second motor 16 is changed, combined with the position characteristics of the flexible transmission of the transmission disc 18 and the transmission belt 19, so that the input power of the second motor 16 and the rock breaking resistance are adaptively matched.

[0045] In use, when the second motor 16 is started, it drives the transmission shaft 17 to rotate, thereby driving the transmission disc 18 to rotate, and the transmission disc 18 drives another transmission disc 18 to rotate through the plurality of transmission belts 19, and then drives the main shaft 12 to rotate. When the rock breaking resistance is large, the rotation resistance of the main shaft 12 increases, the torque transmission between the two transmission discs 18 increases, and the torsion angle of the transmission belt 19 increases. At this time, the transmission disc 18 connected to the transmission shaft 17 will overcome the elastic force of the spring 27 and move axially, thereby driving the shaft moving frame 28 to move axially, so that the contact position of the primary coil 25 and the secondary coil 23 changes, the number of turns of the secondary coil 23 increases, the input voltage of the second motor 16 increases, and the input power increases. Conversely, it is reduced.
